Abstract: BACKGROUND: The in-depth understanding of human anatomy is the foundation for safety in nursing practice. Augmented reality is an emerging technology that can be used for integrative learning in nursing education. OBJECTIVE: The study aimed to develop a human anatomy-based skill training system and pilot test its usability and feasibility. METHODS: Twenty-seven nursing students participated in 3D anatomy-based skill training for intramuscular injection and Levin tube feeding using HoloLens 2. Various user interfaces including pictures, videos, animation graphics, and annotation boxes assisted users with a comprehensive understanding of the step-by-step procedures for these …techniques. A one-group pre-post test was conducted to observe changes in skill performance competency, usability, and learning satisfaction. RESULTS: After study participation, a statistically significant improvement in skill performance competency (p < 0.05) was observed. The usability results showed that students were satisfied with the usefulness of the program (9.55 ± 0.49) and scored highly for the intention to participate in other educational programs (9.62 ± 0.59). A high level of learning satisfaction was achieved (9.55 ± 0.49), with positive responses in fostering students’ engagement and excitement in the application of cutting-edge technology. CONCLUSION: The 3D anatomy-based nursing skill training demonstrated good potential to improve learning outcomes and facilitate engagement in self-directed practice. This can be integrated into undergraduate nursing education as an assistant teaching tool, contributing to the combination of knowledge and practice. Show more

Abstract: BACKGROUND: Elastomeric pumps have a curved infusion rate profile over infusion time. Chemically driven pumps can overcome such limitations of elastomeric pumps and infuse constantly. However, studies on the pharmacokinetic benefit of chemically-driven pumps are insufficient. OBJECTIVE: This study aimed to determine effects of constant infusion with a chemically-driven pump on plasma drug concentrations compared to elastomeric pumps. METHODS: Infusion rate profiles of a chemically driven pump and two elastomeric pumps were measured in vitro tests under three height conditions of drug reservoir. Plasma drug concentrations were estimated using a pharmacokinetic model …of 5-fluorouracil (5FU). RESULTS: The chemically-driven pump was more accurate than elastomeric pumps during the total infusion time (Root-mean-square-error (RMSE): 3% vs. 13%) which thus reduced its deviation of plasma 5FU concentration over time to one-fifth of that with an elastomeric pump. The chemically-driven pump had less than 5% of RMSE despite the influence of height difference. CONCLUSION: Although chemically-driven pumps maintained plasma 5FU concentration successfully and elastomeric pumps did not, both pumps were proper for 5FU infusion because the time-dependent changes in infusion rate did not affect the area under the curve. Chemically driven pumps would be more advantageous for drugs that are sensitive to their plasma concentrations. Show more

Abstract: BACKGROUND: Lung cancer is one of the most common malignant tumours that threaten human health globally. Radical resection under thoracoscopic guidance has been accepted as the major therapeutic option for treating lung cancer clinically. However, the procedure still has some adverse impacts on the comfort of patients following thoracoscopic surgery. OBJECTIVE: To analyse the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery and to evaluate patient comfort. METHODS: With 210 patients with lung cancer undergoing endoscopic surgery as the participants, this study was performed to …assess the reliability and validity of the postoperative comfort scale for patients with lung cancer undergoing endoscopic surgery, with the assessment performed by eight experts. RESULTS: The postoperative comfort scale included 28 items and consisted of four dimensions (physiological, psychological, socio-cultural and environmental). The total Cronbach’s alpha coefficient of the scale was 0.851, and the split-half reliability coefficient was 0.875. Meanwhile, the content validity index (CVI) was 0.875∼ 1, and the scale-level average CVI was 0.99. The Chi-square/degree-of-freedom ratio of construct validity was 2.844, suggesting a good model-fitting. Furthermore, the overall average score of patient comfort was 3.72 ± 0.57, with scores ranging between 3.59 ± 0.71 and 3.83 ± 1.06 across all four dimensions, with the lowest score in the physiological dimension. CONCLUSION: The postoperative comfort scale has good reliability and validity and can be applied for the postoperative comfort assessment of patients undergoing endoscopic surgery for lung cancer. Overall, the degree of patient comfort in this assessment was moderate, meaning targeted measures may be required to further improve patient comfort, especially in the physiological dimension.

Abstract: BACKGROUND: Ectopic pregnancy is a major contributor to maternal morbidity and mortality across the globe. OBJECTIVE: This study aims to investigate the clinical benefits of laparoscopic surgery in treating ectopic pregnancy, and its impact on tubal patency and reproductive outcomes. METHODS: A clinical study was conducted to compare laparoscopic and medical conservative treatment for ectopic pregnancy. A total of 206 patients were treated for ectopic pregnancy at our hospital from January 2018 to June 2020. Among them, 46 underwent laparoscopic ipsilateral salpingectomy, 54 underwent laparoscopic ipsilateral salpingostomy with lesion removal, and 106 were …treated conservatively with medication. RESULTS: The age range and average age of each group are provided, with no significant differences in these general demographic characteristics (p > 0.05). Both the salpingostomy and medication groups had higher rates of ectopic pregnancy compared to the salpingectomy group, with statistically significant differences (p < 0.05). The comparison of ectopic pregnancy rates between the salpingostomy and medication groups showed no significant difference. Within three years, the salpingostomy group had 10 cases of recurrent ectopic pregnancy, with 2 cases on the same side, while the medication group had 18 cases, with 8 cases on the same side. At 3 months after the normalization of blood β -HCG, the salpingostomy group showed 43 cases of tubal patency (patency rate: 79.63%), while the medication group showed 57 cases (patency rate: 53.77%), with a statistically significant difference between the two groups (p = 0.01). CONCLUSION: Laparoscopic surgery for ectopic pregnancy offers significant clinical benefits over conservative medical treatment, including higher rates of tubal patency and improved reproductive outcomes. These findings support laparoscopic surgery as an effective approach for the management of ectopic pregnancy. Show more

Abstract: BACKGROUND: Lung cancer is the most common type of cancer, accounting for 12.8% of cancer cases worldwide. As initially non-specific symptoms occur, it is difficult to diagnose in the early stages. OBJECTIVE: Image processing techniques developed using machine learning methods have played a crucial role in the development of decision support systems. This study aimed to classify benign and malignant lung lesions with a deep learning approach and convolutional neural networks (CNNs). METHODS: The image dataset includes 4459 Computed tomography (CT) scans (benign, 2242; malignant, 2217). The research type was retrospective; the case-control …analysis. A method based on GoogLeNet architecture, which is one of the deep learning approaches, was used to make maximum inference on images and minimize manual control. RESULTS: The dataset used to develop the CNNs model is included in the training (3567) and testing (892) datasets. The model’s highest accuracy rate in the training phase was estimated as 0.98. According to accuracy, sensitivity, specificity, positive predictive value, and negative predictive values of testing data, the highest classification performance ratio was positive predictive value with 0.984. CONCLUSION: The deep learning methods are beneficial in the diagnosis and classification of lung cancer through computed tomography images. Show more

Abstract: BACKGROUND: Understanding complex systems is made easier with the tools provided by the theory of nonlinear dynamic systems. It provides novel ideas, algorithms, and techniques for signal processing, analysis, and classification. Presently, these ideas are being applied to the investigation of how physiological signals evolve. OBJECTIVE: The study applies nonlinear dynamics theory to electroencephalogram (EEG) signals to better comprehend the range of alcoholic mental states. One of the main contributions of this paper is an algorithm for automatically distinguishing between sober and drunken EEG signals based on their salient features. METHODS: The study …utilized various entropy-based features, including ApEn, SampEn, Shannon and Renyi entropies, PE, TS, FE, WE, and KSE, to extract information from EEG signals. To identify the most relevant features, the study employed ranking methods like T -test, Wilcoxon, and Bhattacharyya, and trained SVM classifiers with the selected features. The Bhattacharyya ranking method was found to be the most effective in achieving high classification accuracy, sensitivity, and specificity. RESULTS: Classification accuracy of 95.89%, the sensitivity of 94.43%, and specificity of 96.67% are achieved by the SVM classifier with radial basis function (RBF) for polynomial Kernel using the Bhattacharyya ranking method. CONCLUSION: From the result, it is clear that the model serves as a cost-effective and accurate decision-support tool for doctors in diagnosing alcoholism and for rehabilitation centres to monitor the effectiveness of interventions aimed at mitigating or reversing brain damage caused by alcoholism.

Abstract: BACKGROUND: The nursing model of establishing a chemotherapy safety management supervisory group has guaranteed the safety and effectiveness of intravenous chemotherapy while reducing the adverse effects of chemotherapy and improving patient satisfaction and quality of life. OBJECTIVE: To explore the impact of establishing a nursing supervision group on improving the safety management of patients receiving chemotherapy in the oncology department. METHODS: We selected a total of 60 patients who underwent chemotherapy at the oncology department between January and June 2021 and assigned them to the control group. They received conventional chemotherapy safety management …nursing care. We selected another 60 patients undergoing chemotherapy in the oncology department between July and December 2021 and assigned them to the observation group. They received a nursing intervention model facilitated by the chemotherapy safety supervision team. We compared the intervention effects in the two groups. RESULTS: Patient satisfaction was significantly higher in the observation group than in the control group (P < 0.05); the incidence of post-chemotherapy nausea and vomiting was significantly lower in the observation group than in the control group (P < 0.05); and the self-rating depression scale (SDS) and self-rating anxiety scale (SAS) scores of patients in the observation group were reduced (P < 0.05) and significantly lower than in the control group (P < 0.05). We used the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-core 30 (EORTC-QLQ-C30) and found a statistically significant difference in the quality of life of patients before the nursing intervention and on the day of discharge (P < 0.05). CONCLUSION: The establishment of a chemotherapy safety management supervisory group was effective in reducing the incidence of post-chemotherapy nausea and vomiting as well as the patient’s psychological burden; it could also improve the quality of life of patients and their satisfaction with nursing care.

Abstract: BACKGROUND: The first-line treatment for cervical dystonia (CD) consists of repeated intramuscular injections of botulinum toxin (BoNT). However, the efficacy in some patients may be unsatisfactory and they may discontinue treatment. OBJECTIVE: To examine the factors associated with the maximum rate of remission in patients with CD after initial botulinum neurotoxin type A (or botulinum toxin type A abbreviated as BTX-A or BoNT-A) treatment. METHODS: Patients with CD who received BoNT-A injections were evaluated using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) and the Tsui scale, with follow-up endpoints lasting until the …start of the second injection. Patients who did not receive a second injection of BoNT-A were followed up for at least 5 months. The maximum remission rates were determined using the lowest Tsui and TWSTRS total scores during the follow-up period. We obtained basic information about these patients such as age, gender, duration of disease, presence of additional disease, types of torticollis, presence of anxiety, depression, tremors, single-photon emission computed tomography (SPECT) findings, injected dose, and so on from their medical records. RESULTS: A total of 70 patients with CD participated in this study, with males comprising 35.7% (25 individuals) with an average age of 45 ± 14 years old. The duration of disease was an independent risk factor for determining whether a complete remission has been attained using the Tsui scale (odds ratio [OR] = 0.978, 95% confidence interval [CI]: 0.959–0.997, P = 0.026). The optimal cut-off point for predicting patients who were unable to achieve complete remission based on duration of disease was 7.5 months (AUG = 0.711). Patients with CD with additional disease had greater difficulty achieving complete remission than those with CD alone based on TWSTRS assessments (P = 0.049). During the study, approximately 17% of all participants reported experiencing adverse reactions that lasted between 1 to 3 weeks before disappearing. CONCLUSION: BoNT is an effective and safe method for treating CD. The maximum remission rates of patients after their first injections are influenced by the duration of their disease. Thus, treatment using BoNT injections must be administered as soon as possible. Show more

Abstract: BACKGROUND: Comprehensive geriatric assessment (CGA) has been used in inpatient, outpatient, and emergency patients in Western countries and is an important evaluation tool in medicine. In China, the application of CGA to multiple single diseases has achieved satisfactory intervention effects. OBJECTIVE: To explore the effect of CGA on postoperative quality of life (QoL), psychological state, neurological recovery, and self-efficacy in patients with cerebral hemorrhage. METHODS: In this randomized controlled trial, a total of 133 postoperative patients with cerebral hemorrhage who were treated and nursed in our hospital between March 2019 and March 2021 …were randomly assigned to a control group (68 patients) and an observation group (65 patients). The control group was given a general comprehensive care intervention. The observation group was evaluated using an electronic medical record-based CGA system that assessed patient prognosis and was given individualized interventions based on the CGA findings. The postoperative QoL, psychological state, neurological recovery, and self-efficacy of the two groups were compared. RESULTS: After the intervention, self-decompression, self-decision-making, and positive attitudes of the observation group were higher than those of the control group. However, the National Institute of Health Stroke Scale score of the observation group was lower than that of the control group, the Self-rating anxiety scale and self-rating depression scale scores of the observation group were lower than those of the control group, and the social support score was significantly higher in the observation group than in the control group. After the intervention, the mental vitality, social interaction, emotional restriction, and mental status scores of the observation group were significantly higher than those of the control group. CONCLUSION: Comprehensive evaluation of patients with cerebral hemorrhage based on a CGA, targeting the individual factors that affect the prognosis of patients, and formulating and implementing individualized nursing intervention programs based on the CGA results can effectively relieve the symptoms of cerebral hemorrhage, reduce anxiety and depression, and improve the QoL of patients with cerebral hemorrhage.

Abstract: BACKGROUND: There have been studies on the use of cognitive behavioral nursing intervention (CBNI) but the main subjects were patients with secondary glaucoma and there are fewer studies on the care of congenital glaucoma. OBJECTIVE: To explore the clinical value of cognitive behavioral nursing model in patients with congenital glaucoma. METHODS: One hundred and fifty-three postoperative patients with congenital glaucoma treated in our hospital between January 2021 and December 2022 were prospectively selected for the study and randomly divided into a control group (n = 77) and an …observation group (n = 76). The control group was given routine nursing, and the observation group was given cognitive behavioral nursing mode on the basis of the control group. Anxiety self-assessment scale (SAS), depression self-assessment scale (SDS), Connor-Davidson toughness scale, and treatment adherence evaluation scale were used to evaluate the psychological state, mental toughness, treatment adherence, treatment effect and nursing care satisfaction in the two groups before and after 2 weeks of intervention. The efficacy of the treatment was also assessed by determining the visual acuity (VA), intraocular pressure (IOP), and mean defective (MD) value of the visual field of the two groups of patients. RESULTS: After nursing, the SDS score (46.33 ± 6.16 versus 53.21 ± 5.94) and SAS score (44.41 ± 5.6 versus 52.82 ± 6.31) in the observation group were lower than those in the control group (P < 0.05). The scores of optimism (11.55 ± 1.90 versus 8.20 ± 1.95), self-improvement (22.05 ± 3.60 versus 17.60 ± 4.30), tenacity (37.45 ± 3.10 versus 28.90 ± 4.55) and total score (71.35 ± 8.00 versus 56.85 ± 8.50) in the observation group were higher than those in the control group (P < 0.05). After care, the VA of the observation group (0.95 ± 0.22) was greater than that of the control group (0.84 ± 0.16), and the IOP (14.25 ± 0.58 versus 15.89 ± 0.67) and the MD (5.42 ± 0.46 versus 6.68 ± 0.49) of the observation group were less than that of the control group. The difference between the two groups was statistically significant (P < 0.05). The compliance (96.05% versus 85.71%) and nursing satisfaction (96.10% versus 85.71%) of the observation group were higher than those of the control group (P < 0.05). CONCLUSION: Cognitive-behavioural nursing care for glaucoma patients can improve patients’ mental toughness, improve visual acuity, reduce intraocular pressure and mean visual field defect values, and have a positive effect on enhancing patients’ treatment adherence and nursing satisfaction.

Abstract: BACKGROUND: Passive smartphone-based apps are becoming more common for measuring patient progress after total hip arthroplasty (THA). Optimum activity levels during early THA recovery have not been well documented. OBJECTIVES: Correlations between step-count and patient reported outcome measures (PROMs) during early recovery were explored. This study also investigated how demographics impact step-count during early post-operative recovery. METHODS: Smartphone captured step-count data from 666 THA patients was retrospectively reviewed. Mean age was 64 ± 11 years. 55% were female. Mean BMI was 29 ± 8kg/m 2 …. Mean daily step-count was calculated for each patient over four time-windows: 60 days prior to surgery (preop), 42–49 days postop (6 weeks), 91–98 days postop (3 months), and 183–197 days postop (6 months). Spearman correlation coefficients and linear regression were used to assess the association between PROMs (HOOS-12, HOOS-Jr, and UCLA) were performed. Patients were separated into three step-count levels: low (< 2500 steps/day), medium (2500–5500 steps/day), and high (> 5500 steps/day). Age > 65 years, BMI > 35 kg/m 2 , and sex were used for demographic comparisons. Post hoc analyses were performed using Welch’s unequal variances t -tests, or Wilcoxon rank-sum tests, both with Bonferroni corrections, where appropriate when comparing between groups. Chi-squared analyses were also used when comparing categorical variables. RESULTS: UCLA correlated with step-count at all time-windows (p < 0.001). HOOS12-Function correlated with step-count preoperatively, at 6 weeks, and at 3 months (p < 0.001). High step-count individuals had improved UCLA scores compared to low step-count individuals preoperatively (Δ 1.5, p < 0.001), at 6 weeks (Δ 0.9, p < 0.001), at 3 months (Δ 1.4, p < 0.001), and at 6 months (Δ 1.4, p < 0.001). High step-count individuals had improved HOOS12-Function scores compared to low step-count individuals preoperatively (Δ 9.6, p < 0.001), at 6 weeks (Δ 5.3, p < 0.001), and at 3 months (Δ 6.1, p < 0.001). Males had greater step-count at all time points (p < 0.001). Younger patients and low BMI patients had greater step-count across all time points (p < 0.001). CONCLUSION: High step-count improved PROMs scores compared to low step-count. Early post-operative step-count was significantly impacted by age, sex, and BMI. Generic recovery profiles may not be appropriate across diverse populations. Show more

Abstract: BACKGROUND: Early complications in total knee arthroplasty (TKA) associated with modern robotics platforms integrated with digital balancing technology have not been investigated. OBJECTIVE: The objective was to compare 90-day complication rates between a manual technique and a modern robotic-assisted ligament balancing TKA platform. METHODS: 895 primary TKA procedures from a single surgeon were retrospectively reviewed (614 manual TKA, 281 using a modern robotics platform with an integrated digitally controlled ligament balancing device). Post-operative complications within the 90-day episode of care were recorded by the Michigan Arthroplasty Registry Collaborative Quality Initiative. Differences in complication …rates between techniques were further divided into inpatient hospital, outpatient hospital, and ambulatory surgery center (ASC) cohorts. RESULTS: In the pooled hospital cohort and inpatient hospital cohort, ‘Return to OR’ was significantly lower for the robotic assisted group (1.3% vs 5.2% and 0% vs 4.9%, respectively, p < 0.0370). Specifically, the need for manipulation under anesthesia (MUA) was reduced for the robotics group (0.0% vs 2.5%, p = 0.0352). No differences in overall complication rate or cause of complication was found between manual and robotics cases for the hospital outpatient and ASC cohorts (p ⩾ 0.68). CONCLUSION: Within the hospital setting, robotic assisted ligament balancing technology was associated with reduced 90-day postoperative complications for ‘Return to OR’ and MUA. Show more

Abstract: BACKGROUND: Endothelial dysfunction, the earliest stage of atherosclerosis, can be caused by smoking, but its molecular mechanism requires further investigation. OBJECTIVE: This study aimed to use bioinformatics analysis to identify potential mechanisms involved in smoking-related atherosclerotic endothelial dysfunction. METHODS: The transcriptome data used for this bioinformatics analysis were obtained from the Gene Expression Omnibus (GEO) database. The GSE137578 and GSE141136 datasets were used to identify common differentially expressed genes (co-DEGs) in endothelial cells treated with oxidized low-density lipoprotein (ox-LDL) and tobacco. The co-DEGs were annotated using Gene Ontology (GO) and Kyoto Encyclopedia of …Genes and Genomics (KEGG) databases. Additionally, a protein-protein interaction (PPI) network was constructed to visualize their interactions and screen for hub genes. GSE120521 dataset was used to verify the expression of hub genes in unstable plaques. The miRNA expression profile GSE137580 and online databases (starBase 2.0, TargetScan 8.0 and DGIdb v4.2.0) were used to predict the related non-coding RNAs and drugs. RESULTS: A total of 232 co-DEGs were identified, including 113 up-regulated genes and 119 down-regulated genes. These DEGs were primarily enriched in detrimental autophagy, cell death, transcription factors, and cytokines, and were implicated in ferroptosis, abnormal lipid metabolism, inflammation, and oxidative stress pathways. Ten hub genes were screened from the constructed PPI network, including up-regulated genes such as FOS, HMOX1, SQSTM1, PTGS2, ATF3, DDIT3, and down-regulated genes MCM4, KIF15, UHRF1, and CCL2. Importantly, HMOX1 was further up-regulated in unstable plaques (p = 0.034). Finally, a regulatory network involving lncRNA/circRNA-miRNA-hub genes and drug-hub genes was established. CONCLUSION: Atherosclerotic endothelial dysfunction is associated with smoking-induced injury. Through bioinformatics analysis, we identified potential mechanisms and provided potential therapeutic targets. Show more

Abstract: BACKGROUND: Unicompartmental knee arthroplasty (UKA) is a viable alternative to total knee arthroplasty (TKA) for osteoarthritis patients with single-compartment involvement, with advantages including accelerated recovery, reduced pain, and improved function. Robotic-assisted UKA (rUKA) is a promising development that ensures precise implant positioning and limb alignment. However, concerns about complications remain. OBJECTIVE: This study looks at patient satisfaction as a key metric for determining the efficacy of rUKA versus manual UKA (mUKA). METHODS: The search strategy for this study followed PRISMA. Using precise keywords, PubMed, Scopus, Web of Science, and the Cochrane library were …searched. English articles were searched until August 2, 2023. Selection criteria included mUKA and rUKA patient satisfaction studies. The NOS scale evaluated study quality. Meta-analysis was done with R and heterogeneity analysis. RESULTS: This systematic review examined 5 studies with 1060 UKAs (532 robotic-assisted and 528 manual). Variable satisfaction assessment methods were used. Three studies found no difference in patient satisfaction after robotic-assisted UKA, but two found a higher satisfaction. Meta-analysis showed robotic-assisted UKA improved patient satisfaction (OR = 1.72 [1.25–2.37]). Overall, most studies showed low risk of bias, except one with higher bias. CONCLUSION: This review suggests that robotic assistance may enhance patient satisfaction in UKA procedures. Show more

Abstract: BACKGROUND: Oral squamous cell carcinoma (OSCC) is an infiltrative malignancy characterized by a significantly elevated recurrence rate. Dickkopf-related protein 1 (DKK1), which plays an oncogene role in many cancers, acts as an inhibitor of the Wingless protein (Wnt) signaling pathway. Currently, there is a lack of consensus regarding the role of DKK1 in OSCC or its clinical significance. OBJECTIVE: To examine the role and effect of DKK1 in OSCC. METHODS: The identification of differentially expressed genes (DEGs) in OSCC was conducted by utilizing databases such as The Cancer Genome Atlas (TCGA) and Gene …Expression Omnibus (GEO). A comprehensive analysis of gene expression profile interactions (GEPIA) and Kaplan-Meier curve were conducted to investigate the associations among DEGs, patient survival and prognosis in individuals with OSCC. The biological function of DKK1 in OSCC was investigated by using molecular biology approaches. RESULTS: The expression of DKK1 was found to be upregulated in OSCC tissues at various stages. High levels of DKK1 expression exhibited a positive correlation with the overall survival (OS) and progression-free survival (PFS) rates among OSCC patients. DKK1 knockdown suppressed the proliferation and induced apoptotic response in OSCC cells. Moreover, DKK1 exerted a positive regulatory effect on HMGA2 expression, thereby modulating cell growth and apoptosis in OSCC. The expression of DKK1 was found to be positively correlated with the infiltration of immune cells in patients with OSCC. Additionally, higher levels of CD4 + T cells were associated with improved 5-year survival rates. CONCLUSION: DKK1 is a prognostic biomarker for patients with OSCC. Show more

Abstract: BACKROUND: Periprosthetic joint infection (PJI) is a very important complication that occurs after total joint replacement. Diagnosing PJI is at least as difficult as this disease. There is no biomarker that alone can diagnose PJI. OBJECTIVE: This study aimed to evaluate the effectiveness of large unstained cell percentage (%LUC) in diagnosing PJI and deciding on re-implantation in two stage septic exchange arthroplasty. METHODS: Patients who underwent revision arthroplasty between 2019 and 2023 were screened retrospectively. These patients were grouped as those who underwent two-stage septic exchange and those who underwent aseptic exchange. Prosthesis …removal from the patients who underwent two-stage septic exchange, before spacer application, and on the 3rd post-operative day after spacer application, Blood parameters were collected at the 1st month and before the second stage after the spacer application, and before the revision surgery from the patients who underwent aseptic exchange. White blood cell, neutrophil percentage, %LUC, albumin, sedim and CRP values were checked and recorded one by one from all patients. RESULTS: The data of a total of 233 patients, including 133 patients in the two stage septic exchange group and 100 patients in the aseptic exchange group, were included in the study. When the predictive value of %LUC in PJI was accepted as cut-off 1.75, the sensitivity was 69.2% and the specificity was 73%. The change in %LUC over time in patients who underwent two-stage septic exchange was statistically significant (p = 0.0001). A positive correlation was found between the value of .%LUC after spacer application and the value of CRP before prosthesis protrusion/spacer application surgery, and the Spearman correlation coefficient was found to be 0.005. CONCLUSION: %LUC value can be a promising biomarker for the diagnosis of PJI by considering both sensitivity and specificity rates. Apart from this, it is an easily accessible and effective biomarker for re-implantation decision making and evaluation of response to treatment, especially in two-stage septic exchange surgeries.

Abstract: BACKGROUND: Despite the advancement of new screening strategies and the advances in pharmacological therapies, the cancerization rates of familial adenomatous polyposis (FAP) are stable and even increased in the last years. Therefore, it necessitates additional research to characterize and understand the underlying mechanisms of FAP. OBJECTIVE: To determine the genes that drive the pathogenesis of familial adenomatous polyposis (FAP). METHODS: We performed on a cohort (GSE111156) gene profile, which consist of four group of gene expressions (the gene expressions of cancer, adenoma and normal tissue of duodenal cancer from patients with FAP were …defined as Case N, Case A and Case C respectively, while that of adenoma tissue from patients with FAP who did not have duodenal cancer was Ctrl A). Tracking Tumor Immunophenotype (TIP) website was applied to reveal immune infiltration profile and signature genes of FAP. We merged the genes of key module (pink and midnight module) with signature genes to obtained the biomarkers related with FAP pathogenesis. The expression of these five biomarkers in FAP intratumoral region (IT) and tumor rim (TR) was detected with Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR). RESULTS: In total, 220, 23 and 63 DEGs were determined in Cases C, A and N, in comparison to Ctrl A. In total, 196 and 10 DEGs were determined in Cases C and A, separately, as compared to Case N. A total of four biomarkers including CCL5, CD3G, CD2 and TLR3 were finally identified associated with pink module, while only one biomarker (KLF2) associated with midnight module was identified. All biomarkers were evidently raised in FAP IT tissues utilizing qRT-PCR. CONCLUSION: We identified five potential biomarkers for pathogenesis of FAP to understand the fundamental mechanisms of FAP progression and revealed some probable targets for the diagnosis or treatment of FAP.

Abstract: BACKGROUND: Forensic odontology is a subfield of forensics that can assist in determining age, gender, and other demographic factors. OBJECTIVE: The focus of this research is to ascertain age by tooth volume ratio of permanent maxillary canines using a CBCT scan. METHODS: In this retrospective investigation, 1000 CBCT images were gathered and focused on only fully developed maxillary canines. For each of the maxillary canines, the researchers measured and calculated the volume of the pulp chamber, root canal, and entire tooth using the ITK Snap programme. The pulp volume to tooth volume ratio …was computed. The equation AGE = 59.208 - (583.652 x pulp volume/tooth volume) was then used to compute age. The samples were divided into 5 age groups; 13–20, 21–30, 31–40, 41–50, and 51–60. The age was calculated for samples in each group and it was compared to the actual age. RESULTS: Between individuals’ actual age and computed age, the study discovered a statistically significant positive association. While groups 3, 4, and 5 demonstrated positive but weaker correlations (r = 0.854, r = 0.658, and r = 0.612, respectively), groups 1 and 2 displayed statistically significant strong positive correlations (r = 0.987 and r = 0.923, respectively). The average total discrepancy between the age that was computed and the actual age was 2.45 1.344. CONCLUSION: The study found a statistically significant positive correlation between computed age and actual age, with the younger age groups 1 (13–20) and 2 (21–30) showing the strongest relationships. This underlines its potential success in court, particularly when dealing with young criminals. Show more

Abstract: BACKGROUND: The sublingual vein (SV) is a specialized diagnostic method used in Traditional Chinese Medicine (TCM). Despite its ability to objectively reflect blood flow, SV is often overlooked in clinical practice. OBJECTIVE: This study aims to analyze the core characteristics of SV and investigate the in-depth relationship between its digital characteristics and hypertension. The goal is to find a link between SV and hypertension and break out of the current situation. METHODS: Modern digital analysis techniques were applied to the traditional SV diagnostic theory. In a controlled study with 204 participants, the digital …characteristics of SV were documented using TFDA-1, and its color value was analyzed using TDAS. Morphological characteristics of SV, such as trunklength, width, and tortuosity, were examined by combining computer vision with expert interpretation. This involved the application of automatic ranging methods and a rectangular approximation algorithm, which are novel approaches in the field of TCM. The t -test and Mann-Whitney U test were used to analyze the digital characteristics of SV in hypertension. Binary logistic regression and neural network models were established using machine learning to explore the deep relationship between SV characteristics and hypertension. RESULTS: There was a significant difference of the tortuosity of SV between the two groups (Z = - 2.629, p = 0.009). The results revealed thick width of SV (OR = 2.64, 95% CI: 1.02–6.79) was the risk factor for hypertension. Addition of SV characteristics improved overall percent correct for hypertension prediction to 80%. CONCLUSION: TCM method of diagnosis of SV has been greatly expanded in terms of technical means, and the close relationship between SV and hypertension has been found in clinical data. Show more

Abstract: BACKGROUND: Both highly specialized heart centres and less specialized hospitals care for patients with implantable ICDs/CRT-Ds with remote monitoring. OBJECTIVE: To investigate potential differences in patient treatment according to centre’s ICD implantation volume. METHODS: Based on their 2012 ICD/CRT-D implantation volume, centres enrolled in the NORDIC ICD trial in Germany were assigned to one of three groups: high- (HV, n = 345), medium- (MV, n = 340) or low-volume (LV, n = 189). RESULTS: The …HV-centres had a significant higher CRT-D proportion (41.7%; LV: 36.5%; MV: 23.2%; P 𝑔𝑙𝑜𝑏𝑎𝑙 < 0.001), significant shorter median procedure duration (49 min; MV: 58 min; LV: 60 min; P 𝑔𝑙𝑜𝑏𝑎𝑙 < 0.001) but significant longer median hospital stay (4 days; MV and LV: 3 days; P 𝑔𝑙𝑜𝑏𝑎𝑙 < 0.001) compared to MV- and LV-centres. The X-ray exposure was shorter in MV/HV-centres (MV: 3.4 min; HV: 3.6 min; LV: 5.5 min; P 𝑔𝑙𝑜𝑏𝑎𝑙 < 0.001). Only 3.5% (LV: 2.6%; HV: 3.5%; MV: 4.1%) patients received at least one delivered inappropriate shock and 2.5% (HV: 2.0%; LV: 2.6%; MV: 2.9%) patients had withheld inappropriate ICD shocks without subsequent inappropriate shock delivery within 24.5 months of median follow-up. CONCLUSION: Implantation volume-dependent differences were observed in the device selection, procedure duration and x-ray exposure duration. Remote monitoring in combination with adequate response pattern prevented imminent inappropriate shocks in all three groups. Show more

Abstract: BACKGROUND: Tongue diagnosis is a crucial traditional Chinese medicine (TCM) inspection method for TCM syndrome differentiation and treatment. OBJECTIVE: The primary research focus was on tongue image characteristic parameters of patients with non-small cell lung cancer (NSCLC). Analysis of the tongue image parameters of various pathological stages of NSCLC provides technical support for establishing an integrated Chinese and Western auxiliary diagnosis and efficacy evaluation medicine system for lung cancer that integrates tongue image features. METHODS: Tongue image characteristics of 309 patients with NSCLC and 206 controls were collected and analyzed clinically. The T …-test or rank sum test and logistic regression analysis were applied to analyze the characteristics of tongue image indicators of different pathological stages of NSCLC. RESULTS: There were differences in tongue image characteristics in the NSCLC group compared to the control group. The tongue quality and brightness of the tongue coating in the NSCLC group increased, the red component was reduced, the tongue coating thickened, and the yellow component increased compared to the healthy control group. A comparison of tongue image indexes of NSCLC in different pathological stages showed that stage IV had lower TB-b and higher TB-a than stage I. In addition, stage IV had lower TB-b than stage II + III, showing an increase in the blue and red components of the tongue in stage IV and the appearance of cyanotic tongue features. CONCLUSION: The tongue image characteristics of NSCLC patients differed from those of the control group. Tongue imaging indicators can reflect the characteristics of tongue images of patients with NSCLC. The tongue image characteristics of patients with stage IV lung cancer are bluish and purple compared with those with stage I, II, and III. It is suggested that the tongue’s image characteristics can be used as a reference for the pathological classification of NSCLC and judgment of the disease process. Show more

Abstract: BACKGROUND: The main treatment method for end-stage renal disease (ESRD) is maintenance hemodialysis (MHD). With the continuous improvement of dialysis technology, the survival period of MHD patients has been effectively prolonged, but dialysis technology still cannot completely replace renal function. OBJECTIVE: To study the dietary compliance and its correlation with thirst in MHD patients and to provide guidance for clinical development of corresponding intervention countermeasures. METHODS: A total of 90 patients who received MHD treatment from March 2021 to March 2022 were selected as objects. The Renal Adherence Attitudes Questionnaire (RAAQ) and the …Renal Adherence Behaviour Questionnaire (RABQ) were used to analyze the dietary compliance and thirst status of patients. Pearson correlation analysis was used to analyze the correlation between diet compliance and thirst. RESULTS: Positive correlations were found between VAS and DTI, SXI and TDS (P < 0.05). Social restrictive attitude was positively correlated with VAS, DTI, SXI, TDS, acceptance attitude and compliance in facing difficulties (P < 0.05), and negatively correlated with self-care compliance (r = - 0.35, P < 0.05). Health attitude was positively correlated with VAS, DTI and SXI (P < 0.05). Acceptance attitude was positively correlated with DTI, SXI and TDS (P < 0.05). High RAAQ was associated with high VAS (b = 0.11, 95% CI: 0.05, 0.18), DTI (b = 0.28, 95% CI: 0.17, 0.38), SXI (b = 0.24, 95% CI: 0.14, 0.34) and TDS (b = 0.26, 95% CI: 0.13, 0.4). CONCLUSION: The overall performance of dietary compliance in patients with MHD is at a moderate level, and dietary compliance is negatively correlated with disease perception. Show more

Abstract: BACKGROUND: Malnutrition is a widespread problem in critically ill patients with neurological disorders. OBJECTIVE: The purpose of this study is to investigate the effect of a multidisciplinary collaborative nutritional treatment mode based on a standardized unit for nutritional support on the outcome metrics in patients with neurological disorders who are critically ill. METHODS: We enrolled 84 participants who were hospitalized in the intensive care unit (ICU) of Yancheng No. 1 People’s Hospital for neurological disorders between June 2018 and December 2021. The participants were randomly assigned to the control group and the test …group. The control group received traditional nutritional support, while the test group was treated with a multidisciplinary collaborative nutritional treatment mode based on a standardized unit for nutritional support. We collected the general information, feeding tolerance (FT), nutritional risk score, and laboratory indicators before intervention, after intervention for one week, and after intervention for 2 weeks, and other data of the participants. RESULTS: After the intervention, the test group scored significantly lower than the control group in the incidence of gastroparesis and diarrhea, as well as the NUTRIC score, with statistically significant differences (P < 0.001). The prealbumin levels in the test group increased progressively prior to intervention, after intervention for one week, and after intervention for two weeks. Compared to the control group, the test group had higher prealbumin levels prior to intervention, after intervention for one week, and after intervention for two weeks, with statistically significant differences (P < 0.001). CONCLUSION: We developed a multidisciplinary collaborative nutritional treatment model based on a standard unit for nutritional support. This model can improve neural function, FT, and pertinent outcome indicators and is generally applicable. Show more

Abstract: BACKGROUND: Endoluminal interventions have become one of the main options for the treatment of arteriosclerosis obliterans (ASO). OBJECTIVE: To explore the effect of hydration therapy and nursing intervention on the prevention of contrast-induced nephropathy (CIN) after interventional treatment of lower extremity ASO. METHODS: A convenience sampling method was used to select 94 patients who received ASO treatment in our hospital from March 2019 to May 2021 as the study subjects. All patients underwent endovascular interventional therapy and were randomly divided into two groups by the random number table method, with odd numbers entering …the observation group (n = 47) and even numbers entering the control group (n = 47). The control group received routine nursing intervention, while the observation group underwent hydration therapy and had a corresponding nursing intervention scheme. The clinical efficacy of the two groups and the incidence of contrast-induced nephropathy after interventional therapy were compared, and an evaluation of satisfaction within the two groups was performed via a questionnaire. RESULTS: The total effective rate of patients in the observation group was higher after hydration treatment (97.87% vs 87.23%, p < 0.05). The blood urea nitrogen, creatinine, and β 2 microglobulin levels in the observation group were significantly lower than those in the control group after the intervention (p < 0.05). Patients in the observation group had higher nursing satisfaction after using preventive measures of hydration therapy combined with nursing interventions (100% vs 89.36%, p < 0.05). CONCLUSION: Hydration therapy and nursing intervention can effectively prevent CIN after interventional treatment of lower extremity ASO. After interventional therapy, patients had better clinical outcomes, lower biochemical indexes and improved satisfaction evaluations. The therapy is worthy of clinical promotion and application.

Abstract: BACKGROUND: Following the latest trends in the development of artificial intelligence (AI), the possibility of processing an immense amount of data has created a breakthrough in the medical field. Practitioners can now utilize AI tools to advance diagnostic protocols and improve patient care. OBJECTIVE: The aim of this article is to present the importance and modalities of AI in maternal-fetal medicine and obstetrics and its usefulness in daily clinical work and decision-making process. METHODS: A comprehensive literature review was performed by searching PubMed for articles published from inception up until August 2023, including …the search terms “artificial intelligence in obstetrics”, “maternal-fetal medicine”, and “machine learning” combined through Boolean operators. In addition, references lists of identified articles were further reviewed for inclusion. RESULTS: According to recent research, AI has demonstrated remarkable potential in improving the accuracy and timeliness of diagnoses in maternal-fetal medicine and obstetrics, e.g., advancing perinatal ultrasound technique, monitoring fetal heart rate during labor, or predicting mode of delivery. The combination of AI and obstetric ultrasound can help optimize fetal ultrasound assessment by reducing examination time and improving diagnostic accuracy while reducing physician workload. CONCLUSION: The integration of AI in maternal-fetal medicine and obstetrics has the potential to significantly improve patient outcomes, enhance healthcare efficiency, and individualized care plans. As technology evolves, AI algorithms are likely to become even more sophisticated. However, the successful implementation of AI in maternal-fetal medicine and obstetrics needs to address challenges related to interpretability and reliability. Show more

Abstract: BACKGROUND: Newborn hypothermia at birth remains as global challenge across all settings. The prevention of delivery room hypothermia at birth could potentially reduce neonatal morbidity and mortality. OBJECTIVE: To compare the heat conservation efficacy of Neohelp and Neowrap and evaluate the heat production efficacy of trans-warmer infant mattress (TWM) in a laboratory setting. METHODS: A beaker of water was heated at 60 ∘ C was covered by Neohelp or two layers of Neowrap and left to cool in an open room for 90 minutes and calculated the decay constant. Using …infra-red camera, we measured the maximum temperature and time taken to reach the temperature in the TWM. RESULTS: Neowrap took 863 seconds for the temperature to drop from 37 ∘ C to 35 ∘ C, compared with 941 seconds with Neohelp. When activated TWM reached a maximum temperature of 39.3 ± 0.1 ∘ C. It took 30 seconds when the activator was placed in the centre, compared with 88 seconds when it was at the corner. CONCLUSION: Compared to Neowrap, Neohelp had better heat conservation properties. Activating the metal disk from the TWM center would deliver quicker heat. Show more

Abstract: BACKGROUND: Diabetic kidney disease (DKD) is an important microvascular complication of diabetes mellitus (DM). OBJECTIVE: This study aimed to develop predictive nomograms to estimate the risk of DKD in patients with type 2 diabetes mellitus (T2DM). METHODS: The medical records of patients with T2DM in our hospital from March 2022 to March 2023 were retrospectively reviewed. The enrolled patients were randomly selected for training and validation sets in a 7:3 ratio. The models for predicting risk of DKD were virtualized by the nomograms using logistic regression analysis. RESULTS: Among the …enrolled 597 patients, 418 were assigned to the training set, while 179 were assigned to the validation set. Using the predictors included glycated hemoglobin A1c (HbA1c), high density lipoprotein cholesterol (HDL-C), presence of diabetic retinopathy (DR) and duration of diabetes (DD), we constructed a full model (model 1) for predicting DKD. And using the laboratory indexes of HbA1c, HDL-C, and cystatin C (Cys-C), we developed a laboratory-based model (model 2). The C-indexes were 0.897 for model 1 and 0.867 for model 2, respectively. The calibration curves demonstrated a good agreement between prediction and observation in the two models. The decision curve analysis (DCA) curves showed that the two models achieved a net benefit across all threshold probabilities. CONCLUSION: We successfully constructed two prediction models to evaluate the risk of DKD in patients with T2DM. The two models exhibited good predictive performance and could be recommended for DKD screening and early detection. Show more

Abstract: BACKGROUND: Bonding between metal and ceramic is one of the most important aspects of a successful prosthesis. Various methods have been recommended for preparing the metal surface to enhance the bond between metal and ceramic including the use of a metal bonding agent. OBJECTIVE: This study aims to evaluate and compare the shear bond strength of the metal-ceramic (M-C) interface after combinations of various surface treatments including the application of a metal bonding agent. METHOD: 40 Ni-Cr alloy specimens were made and divided into 4 groups of 10 each based on the combination …of surface treatments. Sandblasting, surface grinding, and Oxidation heat treatment (OHT) were performed on specimens from Group 1 (Control). In addition, Group 2 specimens received ultrasonic cleaning, Group 3 steam cleaning, and Group 4 metal bonding agent application. Following surface treatments on all specimens, porcelain build-up was performed, and shear bond strength was tested in a Digital Universal testing machine. The statistical tests used were independent t -test and ANOVA. RESULTS: Results revealed that Group 4 specimens had the highest mean value of shear bond strength of 39.087 MPa while Group 3 specimens showed the least mean shear bond strength of 18.154 MPa with highly statistically significant results (p < 0.001). CONCLUSION: The surface treatments and application of bonding agent to metal prior to porcelain application resulted in increased shear bond strength of the metal-ceramic interface. Show more

Abstract: BACKGROUND: Patient obesity is a risk factor for poor acetabular cup positioning in total hip arthroplasty (THA). OBJECTIVE: To assess the impact of using a novel, fluoroscopy-based robotic THA system on acetabular cup placement in obese versus non-obese patients. METHODS: A review of 105 consecutive manual unassisted (mTHA) (47 Obese/58 Non-obese) and 102 robotic-assisted (RA-THA) (50 Obese/52 Non-obese) primary, direct anterior approach THA procedures was conducted. All cases were performed by a single surgeon, for a pre-operative diagnosis of osteoarthritis, avascular necrosis, or rheumatoid arthritis. Obesity was defined as a Body Mass Index …(BMI) ⩾ 30 kg/m 2 . Outcomes included acetabular cup inclination and anteversion, and the proportion of cups within the Lewinnek safe-zone. RESULTS: Obese patients in the mTHA cohort had larger cup inclination angles on average compared to non-obese patients (44.82 ∘ ± 6.51 vs. 41.39 ∘ ± 6.75; p = 0.009). Obese mTHA patients were less likely to have cup placement within the Lewinnek zone compared to non-obese mTHA patients (0.48 vs. 0.67; p = 0.027). Obesity had no effect on the accuracy of RA-THA. CONCLUSION: Obesity affects the placement of the acetabular component in manual THA. The novel, fluoroscopy-based robotic THA system in this study demonstrated accurate cup placement regardless of obesity status. Show more

Abstract: BACKGROUND: The use of indwelling closed thoracic drainage tubes in the wedge resection of the lungs is of great significance to postoperative recovery. However, there are potential risks. OBJECTIVE: To explore the design feasibility and application effect of triple-buffer-system-fixed small-diameter (18 F) thoracic closed drainage tubes following lung wedge resection. METHODS: A total of 136 patients with indwelling thoracic drainage tubes following pulmonary wedge resection were recruited, with 70 patients allocated to the control group and 66 to the experimental group. The drainage tube in the experimental group was fixed with the triple-buffer …system, while that in the control group was fixed using the conventional lifting platform method. The incidence of unplanned extubation, the indwelling time of the drainage tube and the time and material costs, as well as information regarding any subcutaneous emphysema and skin tension blisters, were recorded following the operation. The pain and degree of comfort were assessed using a chi-square test and a rank sum t -test to compare the differences between the two groups. RESULTS: There were no statistically significant differences in terms of age, gender and sweating between the two groups. Compared with the control group, the unplanned extubation rate of the experimental group was lower (χ 2 = 8.513; P = 0.004), the indwelling time of the drainage tube was shorter (t = 2.108; P = 0.037), the cumulative material cost was lower (t = 3.778; P < 0.001), the time cost was also lower (Z = 2.717; P = 0.008), the degree of comfort was higher (Z = 2.752; P = 0.006), and the degree of pain was lower (Z = 4.019; P < 0.001). The incidence of subcutaneous emphysema was significantly lower in the experimental group than in the control group (χ 2 = 8.513; P = 0.004). CONCLUSION: The use of the triple-buffer system to fix small-diameter (18 F) thoracic closed drainage tubes can reduce the unplanned extubation rate, indwelling time of the drainage tube and the incidence of adverse reactions.

Abstract: BACKGROUND: Using a COOK ® Cervical Ripening Balloon (CCRB) for cervical maturity has become a common clinical practice for the induction of labour (IOL). OBJECTIVE: To develop and validate a predictive instrument that could estimate the risk of a caesarean after IOL in term pregnancies with CCRB treatment. METHODS: The medical records of 415 pregnant women requiring IOL from January 2018 to October 2022 were retrospectively reviewed and randomly selected for training (290) and validation (125) sets in a 7:3 ratio. A model for predicting the risk of a …caesarean was virtualised by a nomogram using logistic regression analysis. RESULTS: After completing the multivariate analysis, parity (odds ratio [OR] = 0.226; p = 0.017), modified Bishop score at induction (OR = 0.688; p = 0.005) and the artificial rupture of membranes (OR = 0.436; p = 0.010) were identified as the predictors for implementing a caesarean delivery after IOL. The decision curve analysis showed that the model achieved a net benefit across all threshold probabilities. CONCLUSION: We successfully constructed a nomogram for caesarean delivery after IOL in pregnancies with CCRB treatment using factors including parity, modified Bishop score at induction and the artificial rupture of membrane.

Abstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory complication among the elderly, and its severity can escalate to respiratory failure as the disease progresses. OBJECTIVE: To evaluate the application value of non-invasive ventilation in the clinical treatment of patients with COPD and lung cancer. This study assesses its therapeutic effects and its impact on patients’ quality of life (QoL) as measured by the Functional Assessment of Cancer Therapy-Lung (FACT-L) scale. METHODS: A retrospective analysis was conducted on clinical data from 102 patients with COPD and lung cancer. Patients were divided into …two groups: the control group (n = 48), who received conventional treatment, and the observation group (n = 54), who received non-invasive positive pressure ventilation (NIPPV) in addition to conventional treatment. Relevant indicators of curative effect, including blood gas indices, incidence of dyspnoea, improvements in mental health and appetite, and FACT-L QoL scores, were analysed at 2 weeks, 1 month, and 6 months post-treatment. RESULTS: At 2 weeks post-treatment, the observation group who had used NIPPV showed significant improvements in blood gas indices, dyspnoea, mental state and self-care ability compared with the control group (p < 0.05). At 1 month, these benefits persisted and included improved maintenance of body weight (p < 0.05). By 6 months, the observation group had a lower incidence of pulmonary encephalopathy (p < 0.05), and QoL, as measured by the FACT-L scale, improved significantly in the observation group but declined in the control group (p < 0.05). CONCLUSION: NIPPV demonstrates significant efficacy in treating COPD patients with lung cancer, particularly in enhancing curative effects and improving patients’ QoL. Show more

Abstract: BACKGROUND: Humeral fracture is a common long bone fracture in orthopedic clinical diagnosis and treatment. OBJECTIVE: To investigate the local temperature increase owing to changes in the specific absorption ratio (SAR) of the human body caused by humeral bone nails during magnetic resonance imaging (MRI). METHODS: A refined geometric model of the upper body was constructed via data segmentation and post-processing using the digital human image dataset. Finally, the geometric model was imported into COMSOL, a 3-T magnetic resonance coil was built, and the operating frequency (128 MHz) was set to analyze the …SAR of the bone-nail pair and temperature changes. RESULTS: The analysis of the changes after bone-nail implantation under different tissue conditions revealed that the SAR and temperature after implantation and fixation were three times higher than those before, and the areas with abrupt changes in SAR and temperature were primarily concentrated in the bone-nail area. CONCLUSION: In MRI, metal implants can cause local elevation of the SAR near the implant in the human body, resulting in a temperature increase around the implant. Consequently, long-term scanning can damage the human body. Show more

Abstract: BACKGROUND: Graphic type differentiation of cell count data of synovial aspirates is a new method for the diagnosis of early and late periprosthetic joint infection. OBJECTIVE: The aim of the study was to analyse if the same 6 LMNE-types can be differentiated in the new Yumizen H500 cell counter as it was the case for the old cell counter ABX Pentra XL 80 of previous publications, to verify if the erythrocyte and thrombocyte curves of the new device give additional information and to calculate the difference of cell count in LMNE-type I and III (with abrasion) …in the cell counter and in the manual counting chamber (Neubauer improved). METHODS: 450 aspirates of 152 total hip arthroplasties and 298 knee arthroplasties obtained for the diagnosis of periprosthetic joint infection were analysed with the Yumizen H500. RESULTS: All LMNE-matrices of the 450 aspirates could assigned to one of the six LMNE-types. There were 76 LMNE-type I, 72 LMNE-type II, 14 LMNE-type III, 241 LMNE-type IV, 36 LMNE-type V and 12 LMNE-type VI. The erythrocyte and thrombocyte distribution curves were very helpful for differentiation of hematoma and infection. The cell count in the manual counting procedure was lower than in the cell counter: for the LMNE-type I (abrasion type) the median of the difference was 925/μ L (median) and for the LMNE-type III (combined type of infection and abrasion) 3570/μ L (median). CONCLUSION: The described graphic type differentiation is a new and helpful method for differentiation of hematoma and early PJI as well as abrasion and late PJI. Show more

Abstract: BACKGROUND: Robotic assistance in total hip arthroplasty (RA-THA) has been shown to minimize laterality-based differences in acetabular cup positioning. OBJECTIVE: To determine if the use of a novel, fluoroscopy-based RA-THA system mitigates differences in acetabular cup placement between left (L) and right (R) side hip procedures, when compared to manual, fluoroscopic-assisted technique. METHODS: We conducted a retrospective review of 106 consecutive mTHA (40 L/66 R) and 102 RA-THA (48 L/54 R) primary direct anterior approach procedures. All cases were performed by a single right-hand-dominant surgeon, for a pre-operative diagnosis of osteoarthritis, avascular necrosis, …or rheumatoid arthritis. Outcomes included acetabular cup inclination and anteversion, and the proportion of cups within the Lewinnek safe-zone. RESULTS: The average inclination of mTHA L cases was smaller than that of mTHA R cases (41.10 ∘ ± 7.38 vs. 43.97 ∘ ± 6.27; p = 0.04). For RA-THA, L and R cup angles were similar. There were fewer overall mTHA hips within the Lewinnek safe-zone compared to RA-THA (0.59 vs. 0.78; p = 0.003), as well as fewer mTHA R cases than RA-THA R cases (0.59 vs. 0.80; p = 0.03) within safe zone. CONCLUSION: Use of a novel, fluoroscopy-based robotic system mitigates laterality-based differences in acetabular cup placement that were observed in a manual, fluoroscopic-assisted cohort. Show more

Abstract: BACKGROUND: Total knee arthroplasty (TKA) alleviates pain and improves daily living activities in individuals with end-stage osteoarthritis of the knee. However, up to 20% of patients have sub-optimal outcomes after TKA. OBJECTIVE: No studies have clarified the intraoperative factors that affect postoperative range of motion (ROM) after cruciate-retaining (CR) TKA. Thus, this study aims to clarify these factors. METHODS: Patients with knee osteoarthritis with varus knee deformity who underwent CR-TKA between May 2019 and December 2020 were included in this study. One year after surgery, patients were stratified into two groups based on …knee flexion: Group F (over 120 ∘ ) and Group NF (below 120 ∘ ). Patient backgrounds including age, body mass index, hip knee angle, preoperative range of motion for both extension and flexion, intraoperative center joint-gap measurements of 0 ∘ , 30 ∘ , 45 ∘ , 60 ∘ , 90 ∘ , and 120 ∘ of knee flexion using a tensor, intraoperative anterior-posterior (AP) laxity measurements of 30 ∘ and 90 ∘ of knee flexion using an instrumental laximeter were compared between the groups. Univariate analyses between the groups were used to construct the initial model. The receiver operating characteristic curve was also analyzed. The predictive variables included in the final model were selected by stepwise backward elimination. RESULTS: Intraoperative AP laxity with 30 ∘ of knee flexion smaller than 10.8 mm was a significant positive prognostic factor (OR: 1.39, 95% CI: 1.08–1.79, P = 0.011) of postoperative ROM over 120 ∘ of knee flexion one year after surgery. The sensitivity, specificity, PPV, and NPV were 70.9%, 82.4%, 92.9%, and 46.7%, respectively. CONCLUSION: Intraoperative AP laxity smaller than 10.8 mm was a significant positive predictive factor for obtaining knee flexion greater than 120 ∘ one year after surgery when using CR-TKA and its PPV was high up to 92.9%.

Abstract: BACKGROUND: Currently, there are a variety of methods for ultrasound to localize the conus medullaris. A concern is that measured values can be influenced by variations in spinal flexion and extension. OBJECTIVE: To overcome this limitation, the present study measures the horizontal distance (HD) between the end of the conus medullaris and the caudal edge of last vertebral body ossification in normal fetus at different gestational weeks, and analyzes the relationship between the measured value and fetal growth, as well as the utility of these measurements in assessing the position of the conus medullaris. …METHODS: A total of 655 fetuses at gestational weeks 18–40, who underwent routine prenatal ultrasound, were selected in the study. We measured the distance between the end of the cone of the fetal spinal cord and the caudal end of the final vertebral ossification center (Distance1, D1), the distance between the end of the spinal cord cone and the intersection of the extension of D1 with the caudal skin (Distance2, D2), and HD. We analyzed the correlation between the measurements and gestational weeks, established normal reference values, the ratio of D1, D2 and HD to the commonly used growth parameters was calculated. The ratios of D1, D2, HD and the application value of each ratio phase were analyzed, and the reliability analysis of repeated measurement results among physicians was performed. RESULTS: D1, D2 and HD exhibited strong linear correlations with gestational weeks. Among the ratios of D1, D2 and HD to common growth parameters, D2/FL stabilized after 20 weeks of gestation and consistently exceeded 1. Repeatability tests between D1, D2 and HD showed good reliability (P > 0.05). CONCLUSION: D1, D2 and HD are significantly correlated with gestational age. Horizontal distance measurement can effectively determine the position of fetal conus medullaris, enabling rapid prenatal evaluation of low position of conus medullaris and excluding the possibility of tethered cord.

Abstract: BACKGROUND: Implantable medical devices are being valued as one of the developments of wireless biomedical technology. OBJECTIVE: This paper presents a mid-field wireless power transmission (WPT) system, which is designed for implantable applications and operates at the 2.40–2.48 GHz band of Industrial, Scientific, and Medical (ISM). METHODS: A new compact transmitter structure is proposed, and a small 4-C planar ring antenna is designed as the receiving element. A measurement setup is fulfilled on porcine tissues to verify the power transmission system. RESULTS: The experimental results show that the operating bandwidth …is 2.2–2.62 GHz and the transmission coefficient can reach - 26.32 dB at a distance of 50 mm. The effects of tissue differences, placement depth, and different transmission distances were also measured. The displacement and deflection tolerances between the transmitter and the implant receiver also have good performance. In the safety standard of specific absorption rate, for the 1 W output power from the mid-field transmitter, the receiving power of the implantable antenna at the mid-field distance can reach 79.6 mW. CONCLUSION: With measurements of different implantation and transmission distance on pork, the mid-field power transmission efficiency is proven and shows the high performance of the system.

Abstract: BACKGROUND: Acute pancreatitis (AP) is a severe condition with complications that can impact multiple organ systems throughout the body. Specifically, the diffusion of peripancreatic effusion to the pleural cavity is a significant phenomenon in AP. However, its pathways and implications for disease severity are not fully understood. OBJECTIVE: This study aims to investigate the anatomical routes of peripancreatic effusion diffusion into the pleural cavity in patients with AP and to analyze the correlation between the severity of pleural effusion (PE) and the computed tomography severity index (CTSI) and acute physiology and chronic health evaluation II (APACHE …II) scoring system. METHODS: 119 patients with AP admitted to our institution were enrolled in this study (mean age 50 years, 74 male and 45 female). Abdominal CT was performed, and the CTSI and APACHE II index were used to evaluate the severity of the AP, Meanwhile, the prevalence and semiquantitative of PE were also mentioned. The anatomical pathways of peripancreatic effusion draining to pleural were analyzed. Finally, the correlation relationship between the severity of AP and the PE was analyzed. RESULTS: In 119 patients with AP, 74.8% of patients had PE on CT. The anatomic pathways of peripancreatic effusion draining to pleural included esophageal hiatus in 33.7% of patients, aortic hiatus in 6.7% of patients and inferior vena cava hiatus in 3.37% of patients. The rating of PE on CT was correlated with CTSI scores (r = 0.449, P = 0.000) and was slightly correlated with the APACHE II scores (r = 0.197, P = 0.016). CONCLUSION: PE is a common complication of AP, which can be caused by anatomic pathways such as diaphragmatic hiatus. Due to its correlation with the CTSI score, the PE may be a supplementary indicator in determining the severity of AP. Show more

Abstract: BACKGROUND: The success of assisted pregnancy relies heavily on the effectiveness of the embryo transfer process. Currently, embryo transfer is typically conducted with the assistance of abdominal ultrasound. OBJECTIVE: The primary aim of this study was to evaluate the influence of targeted nursing interventions on the embryo transfer procedure, its impact on pregnancy outcomes, and the level of patient comfort concerning bladder management throughout the procedure. METHODS: A total of 247 patients who underwent embryo transfer at the Reproductive Center of Peking University People’s Hospital from December 2019 to August 2020 were included …in this study. These patients were categorized into two groups: the control group (n = 124) and the experimental group (n = 123). Within the control group, patients received conventional preoperative education, whereas those within the experimental group were subjected to targeted nursing interventions. Furthermore, patients in the experimental group were furnished with explicit instructions pertaining to the volume and timing of water intake. Multiple factors were assessed in this study, encompassing bladder filling, the quality of uterine imaging, the utilization of assistive devices during the surgical procedure, and pregnancy outcomes. Additionally, a post-operative questionnaire was administered to both groups to gauge their comfort levels regarding urinary retention. RESULTS: Following the targeted nursing intervention, ultrasound scans indicated an increase in bladder depth (5.91 ± 1.76 vs. 5.40 ± 1.61, P = 0.02), resulting in clearer endometrial imaging (96.74% vs. 88.71%, P = 0.02). Additionally, the experimental group reported significantly higher levels of comfort with urine retention (P = 0.01) compared to the control group, and these differences held statistical significance. Furthermore, the pregnancy rate in the experimental group was greater than that in the control group (52.85% vs. 50.8%, P > 0.05). CONCLUSION: Based on the premise that pregnancy rates remain unaffected, the implementation of targeted nursing care has the potential to augment bladder filling, enhance the quality of endometrial imaging, reduce the requirement for instrument-assisted embryo transfers, and notably enhance the comfort of patients in relation to urine retention.

Abstract: BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) have been shown to die mainly due to disease-induced acute respiratory distress syndrome (ARDS). Prone position ventilation (PPV) is an important ventilation strategy in the management of patients with ARDS. OBJECTIVE: To investigate the application of PPV in ventilation strategies for patients with COVID-19. METHODS: Three hundred patients with COVID-19 admitted to the Intensive Care Unit (ICU) of Shanxi Bethune Hospital from January 2020 to June 2021 were retrospectively collected. Based on body position and conscious state, all patients were divided into three groups: intubation prone …position group (n = 110), awake prone position group (n = 90) and supine position group (n = 100); The acute physiology and chronic health evaluation II (APACHE-II) scores, blood gas indicators, complications and other relevant clinical indicators were compared among the three groups. One-way ANOVA was used to compare means between multiple groups for quantitative information that conformed to a normal distribution. Repeated measures ANOVA was used for repeated measures data. Component comparisons were made using the Kruskal-Wallis H rank sum test for non-normally distributed quantitative data. RESULTS: One-way repeated-measures ANOVA main effect analysis showed different effects of different treatments on PaO2 in patients with COVID-19 (F treatment = 256.231, P < 0.05), with the order of awake prone position group > intubation prone position group > supine position group. The effects of the three different treatments on P/F in patients with COVID-19 (F treatment = 311.661, P < 0.05), with the order of awake prone position group > supine position group > intubation prone position group; Moreover, the three treatments had different effects on APACHE II scores in patients with COVID-19 (F treatment = 201.342, P < 0.05), with the order of intubation prone position group > supine position group > awake prone position group. CONCLUSION: Intubation prone position and awake prone position can improve lung function to some extent in patients with COVID-19, and should be applied as early as possible in patients with COVID-19-induced ARDS.

Abstract: BACKGROUND: The use of telemonitoring electrocardiogram (ECG) improves the detection rate of various arrhythmias as it offers an extended recording time and does not impose activity restrictions. However, many community hospitals lack the resources to conduct this test due to a lack of cardiac function specialists and antiquated screening equipment. OBJECTIVE: To establish a digital ECG telemonitoring system and remote consultation service between tertiary hospitals and community medical service stations to improve diagnosis and treatment effectiveness. METHODS: We used the PI ECG telemonitoring data acquisition system, with a personal digital assistant (PDA) or …computer serving as the platform for ECG acquisition, storage, display, printing, and transmission. We introduced this system to standardize the storage and transmission of ECG telemonitoring data, and ensure accurate transmission, reproducibility, and preservation of data. RESULTS: The implementation of the PI ECG telemonitoring data acquisition system enabled the sharing of remote ambulatory electrocardiography data between Beijing Shijitan Hospital and its affiliated community hospitals. This has resulted in reduced waiting times for patients to receive reports (from 0.3 to 1 hour, to 0.1 or less), shortened consultation times (from 2 hours to 0.1 hour), and improved patient satisfaction with consultations (> 20% of the patients reported they were highly satisfied). The system successfully combined the goals of intelligence, real-time synchronization, and efficiency, revolutionizing ECG telemonitoring diagnosis in the network era. CONCLUSION: Sharing digital telematics information between tertiary and community hospitals enables a tiered approach to diagnosis and treatment and allows for more efficient, accurate, and convenient remote diagnostics.

Abstract: BACKGROUND: With the restoration of the natural hip biomechanics, a successful total hip arthroplasty (THA) and long-term survival is pursued. Although robotic THA (rTHA) has been developed to increase accuracy of implant positioning, leg lengths and offsets, discussions about its radiological and clinical advantages over conventional THA (cTHA) continues. OBJECTIVE: The aim of this study was to compare clinical and radiological outcomes of robotic and conventional THA. METHODS: This retrospective study compares functional and radiological outcomes of 82 rTHA with a matched group of 82 cTHA in terms of age, sex, body mass …index and preoperative functional scores. The minimum follow up was 12 months for all patients. Functional outcomes were Harris Hip Score (HHS) and the Western Ontario and McMaster University Osteoarthritis index (WOMAC) evaluated pre- and postoperatively. Radiological evaluations included position of cup placement according to Lewinnek and Callanan safe zones, Canal Fill Ratio (CFR), Leg Length Discrepancy (LLD), Lateral offset (LO) and Femoral Component Alignment (FCA). Complications were also evaluated. RESULTS: In the rTHA group, 91.5% (75 out of 82) of the acetabular cups were positioned within the safe zone whereas it was 63.4% (52 out of 82) for the cTHA group (p < 0.001). According to Callanan, they were 84.1% and 50%, respectively (p < 0.001). Between the groups, no statistically significant difference was found in CFR, LLD, HO, FCA, AI, AA, WOMAC, HHS and major complication rates. CONCLUSION: rTHA is superior to cTHA in terms of accuracy and reproducibility of the cup placement, however no apparent clinical benefit was found in short term follow. Show more

Abstract: BACKGROUND: The implementation of the rotation system in the Chinese medical industry has achieved significant results. OBJECTIVES: The present study aims to 1) explore the strengths, weaknesses, opportunities and challenges of rotational nursing department implementation and 2) provide references for developing nursing staff’s competencies in leadership, performance evaluation, quality of care, communication in relationships and human resources. METHODS: A total of 16 rotational nursing department staff members from a tertiary tuberculosis specialist hospital in Beijing were interviewed, and the interview data were analysed using a strengths, weaknesses, opportunities and threats analysis and class …analysis. RESULTS: The advantages of the rotational nursing department included: (1) stimulating the nursing staff’s enthusiasm and creativity; (2) strengthening the communication and collaboration between departments; (3) improving the detailed management of nursing quality; and (4) enhancing the nursing staff’s comprehensive abilities. The disadvantages included: (1) the design of the rotation programme focusing on practice; (2) a lack of personalisation; and (3) imperfect performance assessment of the rotating staff. Opportunities included: (1) deepening the connotation of nursing job management and (2) developing the construction of nursing discipline and the need for personal career development and value realisation. Threats included the lack of a sound rotation management model to draw on. CONCLUSION: A rotational nursing department is conducive to enhancing the competence of nursing staff in management positions and providing new ideas for hospitals to select and train nursing management talents. By taking full advantage of the benefits of vertical nursing management, designing personalised rotation training programmes, building a diversified learning and training platform and developing a positive performance incentive mechanism is recommended to fully engage the role of rotation in nursing management talent training.

Abstract: BACKGROUND: Robotic-assisted total knee arthroplasty (TKA) have shown promising results in recent years with improved clinical outcomes using standard primary implants. OBJECTIVE: The purpose of this study was to assess the experience of a single center in correcting severe coronal deformities with the use of a robotic-assisted TKA system and an increased constrained implant. METHODS: Between July 2020 and December 2022, 30 knees in 28 patients with a major deformity and an associated ligament laxity requiring an increased constrained implant treated using an imageless robotic-assisted TKA were prospectively enrolled. Patients included in the …study showed a minimum 15 degrees varus or 10 degrees valgus deviation. RESULTS: 20 cases were varus knees and 10 cases were valgus knees. Postoperative neutral alignment was defined as 0 ∘ ± 2.5 ∘ . A CCK implant was used in 20 cases while a Constrained Posterior Stabilized implant was used in 10 cases. A neutral alignment was achieved in all patients. At a minimum 6 months follow up (f-u 6–30 months) clinical outcomes including ROM, KSS, HSS, OKS and WOMAC showed significant improvement and no major complications were registered. CONCLUSIONS: The robotic system showed the achievement of a mechanical alignment with reliable radiographic outcomes and clinical results in the treatment of major deformities of the lower limb with the use of higher constrained implants at short term follow up. Further follow up and studies are necessary to confirm and verify these promising outcomes. Show more

Abstract: BACKGROUND: Rolling is an important developmental milestone for infants where identifying the coordinated movement patterns could facilitate the early identification of motor development delays. Current methods for identifying coordinated movements of rolling are limited to a laboratory setting and not feasible for clinicians. OBJECTIVE: To develop video-based methods in which six coordinated movements, previously defined through motion capture, can be identified through video alone. METHODS: Forty-five videos of sixteen healthy infants achieving a roll were used to develop the video-based methodology and twenty-four videos had corresponding motion capture data used for validation. Four raters …comprised of researchers and a clinician identified rolling coordination using the new video-based methods. A Fleiss’ Kappa statistical test determined the inter- and intra-rater reliability of agreement for the new methodology and compared it to motion capture. RESULTS: The comparison of the motion capture and video-based methods resulted in substantial agreement. The video-based methods inter- and intra-rater reliability were substantial and almost perfect, respectively. CONCLUSIONS: We developed reliable methodology to accurately identify the coordinated movements of infant rolling using only 2D video. This methodology will allow researchers to reliably define coordinated movements of infants through video alone and may assist clinicians in identifying possible motor development delays and disorders.

Abstract: BACKGROUND: During the COVID-19 pandemic, the mobile field hospital, a rapidly deployable healthcare facility for emergency care, was effective in ensuring rapid diagnosis and treatment of patients with mild or asymptomatic SARS-CoV2 infections, effectively preventing the spread of COVID-19. OBJECTIVE: We conducted a survey to gain a thorough understanding of the epidemiological traits among the elderly who contracted the Omicron variant of the SARS-CoV-2 virus at a mobile field hospital set up at the National Exhibition and Convention Center (Shanghai). METHODS: A cross-sectional study approach was employed to examine various factors such as …demographic characteristics, clinical features, vaccination status, and nucleic acid testing. We utilized the DezhenTech Integrated Electronic Medical Record Platform (Municipal Isolation Hospital) to collect data and focused on elderly individuals infected with COVID-19 in the fifth isolation zone of the mobile field hospital set up at the National Exhibition and Convention Center (Shanghai). The patients were categorized into different age groups for analysis. RESULTS: Among the 3,183 elderly patients, 54.7% were males and 45.3% were females, with an average age of 65.32 ± 4.41 years. Among them, 47.8% (1523/3183) were 60–64 years old, 34.0% (1082/3183) were 65–69 years old, 14.0% (444/3183) were 70–74 years old, 3.2% (103/3183) were 75–79 years old, and 1.0% (31/3183) were ⩾ 80 years old. The majority (95.7%) of the elderly patients with chronic conditions had hypertension, diabetes, and coronary heart disease. The first viral nucleic acid screening showed a higher positive rate in the community and hospital fever clinics. The cumulative positive rate of the nucleic acid test in the mobile field hospital was 38.7%. The average CT value of the COVID-19 ORF1ab gene was 34.56 ± 5.98, while the average CT value of the N gene was 33.10 ± 6.50. The patients took an average of 3.40 ± 0.45 days to test negative, with a positive rate of 15.4% and an average hospital stay of 7.45 ± 0.53 days. The overall rate of COVID-19 vaccine coverage was 68.0%, with an enhanced coverage rate of 40% and a non-coverage rate of 29.3%. CONCLUSIONS: The overall prognosis for elderly patients who experienced a mild or asymptomatic SARS-CoV-2 Omicron infection at the mobile field hospital was favorable, although the vaccination rate in general was not high. By effectively managing underlying health conditions, the duration of their hospital stay in the mobile field hospital was reduced. Show more

Abstract: BACKGROUND: Nucleolar protein 16 (NOP16) is present in the protein complex of the nucleolus. The NOP16 promoter contains a c-Myc binding site, and the transcriptional regulation by c-Myc directly regulates NOP16 expression levels. OBJECTIVE: Dysregulation of NOP 16 is currently reported in only a small number of cancers. In this study, the expression profile of NOP 16 in hepatocellular carcinoma (LIHC) and its clinical significance were analyzed. METHODS: NOP16 expression in hepatocellular carcinoma (LIHC) and its relationship with the clinical characters of LIHC were examined using the Cancer Genome Atlas (TCGA), the Gene …Expression comprehensive database (GEO), Kaplan-Meier survival analysis, univariate Cox analysis, multivariate Cox analysis, ROC curve analysis of KEGG enrichment, GSEA enrichment, in vitro experiments (e.g., siRNA interference of NOP16 expression in hepatoma cells, Keap1-Nrf2 pathway, cell cycle, cell apoptosis and Transwell assays), and LIHC single-cell sequencing (scRNA). RESULTS: Pan-cancer analysis revealed that NOP16 was highly expressed in 20 cancer types, including LIHC, and high NOP16 expression was an independent adverse prognostic factor in LIHC patients. The expression levels of NOP16 mRNA and protein were significantly increased in tumour tissues of LIHC patients compared to normal tissues. The functions of co-expressed genes were primarily enriched in the cell cycle and reactive oxygen species metabolism. The experimental results showed that knockdown of NOP16 activated the Keap/Nrf2 signalling pathway and inhibited the invasion, migration, and EMT progression of LIHC cells. LIHC scRNA-seq data showed that NOP16 was primarily expressed in T lymphocytes. CONCLUSIONS: NOP16 promoted cancer development in LIHC and caused an imbalance in Keap/Nrf2 signalling, which subsequently caused the aberrant expression of genes typical for EMT, cell cycle progression and apoptosis. NOP16 is a potential prognostic marker and therapeutic target for hepatocellular carcinoma progression. Show more

Abstract: BACKGROUND: Metabolic syndrome (MetS) is a group of comorbidities related to regulating hyperglycemia and acute cardiovascular incidents and complications. With the increasing prevalence in individuals with type 2 diabetes mellitus (T2DM), MetS represents an increasing public health problem and clinical challenge, and early diagnosis is necessary to avoid the accelerated development of diabetic complications. OBJECTIVE: To investigate the role of Complete Blood Count-derived Inflammation Indexes (CBCIIs) in predicting MetS in T2DM individuals. METHODS: The study was designed as a two-year prospective study and included 80 T2DM individuals divided into MetS and non-MetS groups …based on MetS development over two years. The sera samples were analyzed for complete blood count parameters and C-reactive protein (CRP). Based on the laboratory test results, 13 CBCIIs were calculated and analyzed. The receiver operating characteristic (ROC) curve and their corresponding areas under the curve (AUC) were used to determine prognostic accuracy. RESULTS: There were significant differences between T2DM participants with Mets and those without MetS concerning Neutrophil to Platelet Ratio (NPR) values (p < 0.001), Neutrophil to Lymphocyte and Platelet Ratio (NLPR) (p < 0.001), Platelet to Lymphocyte Ratio (PLR) (p < 0.001), Lymphocyte to C-reactive protein Ratio (LCR) (p < 0.001), C-reactive protein to Lymphocyte Ratio (CRP/Ly) (p < 0.001), Systemic immune inflammation index (SII) (< 0.001), and Aggregate Index of Systemic Inflammation (AISI) (p = 0.005). The results of ROC curve analysis have shown that the LCR (AUC of 0.907), CRP/Ly (AUC of 0.907) can serve as excellent predictors, but NPR (AUC of 0.734), NLRP (AUC of 0.755), PLR (AUC of 0.823), SII (AUC of 0.745), and AISI (AUC of 0.688) as good predictors of MetS in T2 DM individuals. CONCLUSION: This study confirms the reliability of the CBCIIs as novel, simple, low cost and valuable predictors of MetS developing in T2DM. Show more
