Abstract: BACKGROUND: Any manipulation of the surface of natural teeth may result in a variation of their colour. The fixed orthodontic treatment (FOT) is one such procedure which alters the enamel surface during the procedure. OBJECTIVE: To clinically evaluate the colour changes in teeth associated with comprehensive FOT (to compare the changes in test and control groups) and to determine the relationship of age and gender on enamel colour due to FOT by using an advanced spectrophotometer. METHODS: The selection of sixty patients for the study was done randomly and among these thirty patients …who underwent the FOT as the case group, the other thirty patients who did not need FOT, were the control group. The recordings of spectrophotometric data were done in a standardized manner for all patients in the labial circular region of every anterior tooth, following debonding and cleaning operations, and before bracket bonding. The Commission Internationale de l’Eclairage’s L*, a*, and b* (lightness, red/green, and blue/yellow) tooth-type characteristics were used to measure color, and the associated color differences (DE) between the groups were computed. One-way ANOVA (a < 0.05) and the paired t -test were used to evaluate any changes in these color characteristics. RESULTS: Fixed orthodontic treatment is associated with changes in colour parameters. L* values decreased (P < 0.001), while a* and b* values increased (P < 0.001) at the end of treatment. All measured tooth types showed significant colour change (DE); their mean differences ranged from 1.64 to 2.96 DE units. CONCLUSIONS: Fixed orthodontics can change the natural colour of teeth. The CIE colour parameters L*, a*, and b* of natural teeth showed statistically significant differences after debonding the orthodontic appliances. The L* values decreased making the teeth look darker. The adolescent and male patients had more tooth colour changes than the adult and female groups. Show more

Abstract: BACKGROUND: Dental education is considered as a complex, challenging and often stressful educational procedure. Acquisition of psychomotor skills by undergraduate students is an important step in many health professions to become a successful professional. During under graduation, class II cavity preparation exercise is of utmost important in dentistry. OBJECTIVE: To compare class II cavities prepared by students after hands-on live demonstration and pre-recorded video demonstration using well-organised evaluation rubrics. METHOD: Preclinical dental students (n = 50) were divided into two groups. The students in group I (n = …25) attended a hands-on live demonstration performed by one faculty while students in group II (n = 25) watched a 15-minute pre-recorded procedural video on the projector. Both groups were appealed to prepare class II cavity for amalgam involving disto-occlusal surface of mandibular second molar articulated on jaw model (TRU LON study model, Jayna industries, Ghaziabad U.P., India). Following completion of the preparations, all teeth were collected, and labelled grades of prepared cavities were given according to prespecified rubrics. The data of scores were presented as means and standard deviation. Statistical analysis of data was executed using SPSS software. A paired t-test was used to compare scores between groups. RESULTS: The study shows that the video-supported demonstration of a cavity preparation was better than the live hands-on demonstration. A higher mean response for the procedural video group was found compared to the live demonstration group (p = 0.000133). CONCLUSION: Pre-recorded video-supported demonstration along with guidance by a tutor may be a viable alternative to hands-on live demonstration in cavity preparation procedures during undergraduate dental training. Moreover, rubric methods can be implemented in the teaching of various preclinical exercises for conservative dentistry and endodontics. Show more

Abstract: BACKGROUND: Currently, surgery is the mainstay of the clinical treatment of vestibular migraine. OBJECTIVE: To investigate the clinical efficacy and safety of using transesophageal echocardiography-guided interventional closure of the patent foramen ovale (PFO) in the treatment of vestibular migraine. METHODS: The study included 52 patients with vestibular migraine who were admitted to our hospital between June 2019 and June 2021. All selected patients underwent a transesophageal echocardiography-guided interventional closure of the PFO and were followed up for one year after surgery. We observed the clinical efficacy and surgical success rate one year after …surgery and compared the improvement in clinical symptoms and perioperative safety at different time points. RESULTS: The overall remission rate and the surgical success rate for the 52 patients with vestibular migraine one year after surgery were 86.54% and 96.15%, respectively. Compared to the pre-surgery levels, there was a significant progressively decreasing trend in the scores on the Headache Impact Test-6 (HIT-6), Visual Analogue Scale (VAS), Migraine Disability Assessment (MIDAS) questionnaire, frequency of headaches, and duration of headaches in patients with vestibular migraine at 1, 3, and 6 months after surgery (P < 0.05). Among the 52 patients, one developed atrial fibrillation three hours after surgery, which then spontaneously converted to sinus rhythm, and none of the other patients had adverse outcomes such as hematoma at the puncture site during the perioperative period. CONCLUSION: Transesophageal echocardiography-guided interventional closure of the PFO for treating vestibular migraine significantly improved the symptoms of migraine in patients, with a high surgical success rate, significant clinical efficacy, and favorable safety.

Abstract: BACKGROUND: Standardised management of day surgery for haemorrhoids and achieving standardised nursing in the painless ward of colorectal surgery are important. OBJECTIVE: To explore the role of segmented nursing pathways in patients undergoing day surgery for anorectal procedures and to provide theoretical and practical guidance for day surgery nursing. METHODS: A total of 146 patients undergoing anorectal surgery in our day surgery ward between April 2023 and July 2023 were selected as the study participants, with 74 patients in the control group receiving routine nursing and 72 patients in the experimental group receiving …segmented nursing. The preoperative preparedness, preoperative anxiety, complication rate, discharge preparedness and nursing satisfaction were compared between the two groups. RESULTS: The experimental group had higher rates of admission before 8:30 am (77.78% vs 45.95%), awareness of the day surgery process (63.89% vs 24.32%), completion rate of preoperative preparation (81.94% vs 59.46%), satisfaction with preoperative preparation (94.44% vs 74.32%), discharge preparedness (112.42 ± 3.28 vs 95.82 ± 3.41) and nursing satisfaction (97.22% vs 70.27%) compared with the control group (P < 0.05). After the intervention, the self-rating anxiety scale score (43.14 ± 12.44 vs 52.51 ± 13.21) and the self-rating depression scale score (45.03 ± 11.37 vs 55.37 ± 10.14) were lower in the experimental group than in the control group (P < 0.05). CONCLUSION: Segmented nursing pathways can improve the preoperative preparedness of patients undergoing day surgery for anorectal procedures, alleviate patient anxiety, enhance discharge preparedness, improve the quality of nursing care and increase nursing satisfaction.

Abstract: BACKGROUND: Globally, pulmonary tuberculosis is a significant public health and social problem. OBJECTIVE: We investigated the factors influencing the hospitalization cost of patients with pulmonary tuberculosis and grouped cases based on a decision tree model to provide a reference for enhancing the management of diagnosis-related groups (DRGs) of this disease. METHODS: The data on the first page of the medical records of patients with the primary diagnosis of pulmonary tuberculosis were extracted from the designated tuberculosis hospital. The influencing factors of hospitalization cost were determined using the Wilcoxon rank sum test and multiple …linear stepwise regression analysis, and the included cases were grouped using the chi-squared automated interaction test decision tree model, with these influential factors used as classification nodes. In addition, the included cases were grouped according to the ZJ-DRG grouping scheme piloted in Zhejiang Province, and the differences between the two grouping methods were compared. RESULTS: The length of hospital stay, respiratory failure, sex, and age were the determining factors of the hospitalization cost of patients with pulmonary tuberculosis, and these factors were incorporated into the decision tree model to form eight case combinations. The reduction in variance (RIV) using this grouping method was 60.60%, the heterogeneity between groups was high, the coefficients of variance ranged from 0.29 to 0.47, and the intra-group difference was small. The patients were also divided into four groups based on the ZJ-DRG grouping scheme piloted in Zhejiang Province. The RIV using this grouping method was 55.24, the differences between groups were acceptable, the coefficients of variance were 1.00, 0.61, 0.77, and 0.87, respectively, and the intra-group difference was significant. CONCLUSION: When the pulmonary tuberculosis cases were grouped according to the duration of hospital stay, respiratory failure, and age, the results were rather reasonable, providing a reference for DRG management and cost control of this disease.

Abstract: BACKGROUND: The substitution of missing teeth with implants is a dependable and anticipated therapeutic approach. Despite numerous studies affirming long-term success rates, there exists a spectrum of potential biological and aesthetic complications. OBJECTIVE: The primary objective of this study was to assess patient responses subsequent to surgical interventions, with a specific emphasis on the utilization of xenogenic collagen matrix (XCM), both with and without the application of a stent secured over healing abutments, in the context of keratinized gingival mucosa augmentation. The principal aim was to evaluate and draw comparisons between the clinical outcomes resulting from these …two procedural approaches, with a particular focus on critical parameters encompassing post-operative complications, patient comfort, and the overall efficacy in achieving successful keratinized tissue augmentation. METHODS: Sixty patients were selected for this study. The patients were divided into three groups: A, B, and a control group, with each group comprising 20 participants. We used XCM in experimental group A, XCM covered with surgical stent in experimental group B, and free gingival graft (FGG) in the control group. After the surgical procedure, patients were required to complete a visual analogue scale (VAS) questionnaire for post-operative complications, and a quality of life (QOL) questionnaire on days 1, 3, and 7. RESULTS: Patients in the experimental groups A and B demonstrated markedly improved outcomes when compared with the control group. Assessments conducted on days 1, 3, and 7 demonstrated diminished levels of pain, bleeding, and swelling in both experimental groups, with experimental group B showing the least discomfort. The incorporation of XCM, either with or without stents, was associated with a reduction in analgesic consumption, underscoring its favorable influence on post-operative comfort, notwithstanding the exception of halitosis in experimental group B. CONCLUSION: Using XCM with or without a stent for keratinized tissue augmentation has better post-operative outcomes associated with reduced swelling, bleeding, and pain based on the QOL survey. This study provides data to support the clinical application of XCM and stents. Show more

Abstract: BACKGROUND: Visualization of sports has a lot of potential for future development in data sports because of how quickly things are changing and how much sports depend on data. Presently, conventional systems fail to accurately address sports persons’ dynamic health data change with less error rate. Further, those systems are unable to distinguish players’ health data and their visualization in a precise manner. An excellent starting point for building fitness solutions based on computer vision technology is the data visualization technology that arose in the age of big data analytics. OBJECTIVE: This research presents a Big …Data Analytic assisted Computer Vision Model (BD-CVM) for effective sports persons healthcare data management with improved accuracy and precision. METHODS: The fitness and health of professional athletes are analyzed using information from a publicly available sports visualization dataset. Machine learning-assisted computer vision dynamic algorithm has been used for an effective image featuring and classification by categorizing sports videos through temporal and geographical data. RESULTS: The significance of big data’s great potential in screening data during a sporting event can be reasonably analyzed and processed effectively with less error rate. The proposed BD-CVM utilized an error analysis module which can be embedded in the design further to ensure the accuracy requirements in the data processing from sports videos. CONCLUSION: The research findings of this paper demonstrate that the strategy presented here can potentially improve accuracy and precision and optimize mean square error in sports data classification and visualization.

Abstract: BACKGROUND: The most effective clinical treatment for hepatocellular carcinoma (HCC) is surgery, but most patients are diagnosed when the disease has progressed. OBJECTIVE: To examine the long-term prognosis and clinical effectiveness of PD-L1 inhibitor-targeted therapy for patients suffering from HCC. METHODS: Ninety-six patients with advanced HCC who were admitted to our hospital between December 2019 and April 2022 were split into two groups based on the treatment plan after a retrospective analysis: 43 patients in the control group underwent sorafenib-based targeted therapy, while dulvalizumab was used to treat 53 patients in the observation …group. Observation indexes were used to assess the clinical effectiveness and long-term prognosis of HCC patients receiving targeted therapy with dulvalizumab, which included the disease control rate, tumor markers, immune function, survival, quality of survival, and the occurrence of unfavorable side effects such as thrombocytopenia, leukopenia, vomiting, and rash. RESULTS: The initial KPS scores, CEA, CA199, AFP, CD3+ , CD4+ , CD4+ /CD8+ , IgG, IgM, and IgA levels did not differ significantly between the two groups (P > 0.05). After treatment, the observation group showed a significantly higher disease control rate (92.45% vs. 74.42%) and improved KPS score, OS, PFS, CD3+ , CD4+ , CD4+ /CD8+ , IgG, IgM, and IgA levels compared to the control group. Additionally, the observation group exhibited significantly reduced CEA, CA199, and AFP levels, and a lower overall incidence of adverse reactions (16.98% vs. 51.16%) compared to the control group (P < 0.05). CONCLUSION: The clinical efficacy of dulvalizumab-targeted treatment of HCC among PD-L1 inhibitors is better, enhancing the disease’s ability to be controlled considerably lowering patients’ levels of tumor markers. This greatly boosts patients’ immune systems, extends their lives and improves the quality of their survival. The frequency of negative reactions is minimal and safe. Show more

Abstract: BACKGROUND: Obstructive sleep apnea (OSA) is a common sleep disordered breathing disorder, which can cause serious damage to multiple human systems. Although polysomnography (PSG) is the current gold standard for diagnosis, it is complex and expensive. Therefore, it is of great significance to find a simple, economical and rapid primary screening and diagnosis method to replace PSG for the diagnosis of OSA. OBJECTIVE: The purpose of this study is to propose a new method for the diagnosis and classification of OSA, which is used to automatically detect the duration of sleep apnea hypopnea events (AHE), so …as to estimate the ratio(S) of the total duration of all-night AHE to the total sleep time only based on the sound signal of sleep respiration, and to identify OSA. METHODS: We performed PSG tests on participants and extracted relevant sleep breathing sound signal data. This study is carried out in two stages. In the first stage, the relevant PSG report data of eligible subjects were recorded, the total duration of AHE in each subject’s data was extracted, and the S value was calculated to evaluate the severity of OSA. In the second stage, only the sleep breath sound signal data of the same batch of subjects were used for automatic detection, and the S value in the sleep breath sound signal was extracted, and the S value was compared with the PSG diagnosis results to calculate the accuracy of the experimental method. RESULTS: Among 225 subjects. Using PSG as the reference standard, the S value extracted from the PSG diagnostic data report can accurately diagnose OSA(accuracy rate 99.56%) and distinguish its severity (accuracy rate 95.11%). The accuracy of the S value detected in the sleep breathing sound signal in the diagnosis of severe OSA reached 100%. CONCLUSION: The results show that the experimental parameter S value is feasible in OSA diagnosis and classification. OSA can be identified and evaluated only by sleep breathing sounds. This method helps to simplify the diagnostic grading of traditional OSA and lays a foundation for the subsequent development of simple diagnostic grading equipment. Show more

Abstract: BACKGROUND: The current 3D-iFlow application can only measure the arrival time of contrast media through intensity values. If the flow rate could be estimated by 3D-iFlow, patient-specific hemodynamics could be determined within the scope of normal diagnostic management, eliminating the need for additional resources for blood flow rate estimation. OBJECTIVE: The aim of this study is to develop and validate a method for measuring the flow rate by data obtained from 3D-iFlow images – a prototype application in Four-dimensional digital subtraction angiography (4D-DSA). METHODS: Using phantom model and experimental circuit with circulating glycerin …solution, an equation for the relationship between contrast media intensity and flow rate was developed. Applying the equation to the aneurysm phantom models, the derived flow rate was evaluated. RESULTS: The average errors between the derived flow rate and setting flow rate became larger when the glycerin flow and the X-rays from the X-ray tube of the angiography system were parallel to each other or when the measurement point included overlaps with other contrast enhanced areas. CONCLUSION: Although the error increases dependent on the imaging direction and overlap of contrast enhanced area, the developed equation can estimate the flow rate using the image intensity value measured on 3D-iFlow based on 4D-DSA.
