ABSTRACT: Background: Direct composite restorations face abrupt temperature changes, varying pH, and surface deterioration in the oral environment. Atomic force microscopy (AFM) provides visual and numerical data on surface roughness. Aim: This study evaluates and compares the surface roughness of composite restorative materials after simulating oral conditions. Materials and Methods: Three composite groups (n = 16 each) were tested. Group A: Microhybrid, Group B: Nanofilled, and Group C: Nanohybrid. Each group was divided into four subgroups (n = 4 each): distilled water (control), black coffee, Coca-Cola, and Red Bull. After thermocycling and immersion, surface roughness was measured using AFM. Results: Nanocomposites with uniform monomodal fillers showed the least surface disintegration and superior properties. Conclusion: Resin chemistry, including filler size and matrix composition, is crucial for composite properties and performance under function. [ABSTRACT FROM AUTHOR]

Context: The Indian government is dispensing newer direct-acting antiviral (DAA) drugs, which may have impact on hepatitis C virus (HCV) patients' quality of life (QoL). Aims: To evaluate different DAA regimens and impact on QoL in terms of quality-adjusted life year (QALY) in HCV patients and to measure cost-effectiveness. Methods: This prospective, observational study was carried out on patients who were diagnosed with HCV. Recruited patients were followed up until 12–24 weeks. Patients were recruited following the selection criteria. Along with demographic and drug details, the regimens used were analyzed and evaluated for cost minimization, cost-effectiveness, and cost–utility analysis. For health quality check, the Chronic Liver Disease questionnaire (CLDQ) was used which was also used for QALY assessment. Data were entered into MS Excel 2016. Difference in between the regimens for total cost was done using unpaired t-test and ANOVA test using SPSS 25.0. Overall cost-effectiveness, cost minimization, cost utility and cost of illness analysis was also calculated.P < 0.05 was considered statistically significant. Results: A total of 31 patients were enrolled. A total of five drugs, namely, sofosbuvir, daclatasvir, ribavirin, velpatasvir, and ledipasvir were widely used. Sofosbuvir was most common (46.25%)component of drug combination in our study. A total of five types of regimen were used according to the genotype of patients. With 44,260.13 ± 15,884.92 INR of the total drug cost, 70.97% of patients spent around 30,000–40,000 INR for the whole pharmacotherapy. The total indirect cost was 2768.39 ± 3916.13 INR with the total direct cost of 48,660.90 ± 15,356.39 INR. The total cost including direct as well as indirect cost spent during 6-month therapy by 61.29% of patients was 40,000–50,000 INR. Based on the CLDQ score, QoL was 64.1 ± 25. Regimen 2 (sofosbuvir + velpatasavir) stood out with the lowest cost. Regimen 5 (ribavirin [200 mg] + sofosbuvir [400 mg] + velpatasvir [100 mg]) was found to be the most cost-effective. Considering 1 life year with good health after treatment, QALY was 0.31. Conclusions: Ribavirin (200 mg) + sofosbuvir (400 mg) + velpatasvir (100 mg) was found to be the cost-effective and cost-saving regimen among DAAs. [ABSTRACT FROM AUTHOR]

The novel coronavirus disease 2019 (COVID-19) is currently causing a major pandemic. It is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the Betacoronavirus genus that also includes the SARS-CoV and Middle East Respiratory Syndrome Coronavirus (MERS-CoV). While patients typically present with fever and a respiratory illness, some patients also report gastrointestinal symptoms such as anorexia, diarrhoea, vomiting and abdominal pain. Studies have identified the SARS-CoV-2 RNA in stool specimens of infected patients, and its viral receptor angiotensin converting enzyme 2 (ACE2) was found to be highly expressed in gastrointestinal tract. This has important implications to the disease management, transmission, and infection control. In this article, we review the important gastrointestinal aspects of the disease.

Metabolic syndrome (MS) and Non-Alcoholic Fatty Liver Disease (NAFLD) spectrum disorder share common risk factors namely obesity, hypertension, diabetes mellitus, and dyslipidemia, and hence, there is evidence now to show that NAFLD may actually be a hepatic manifestation of MS. Moreover, the presence of NAFLD in a patient with metabolic syndrome increases the risk of cardiovascular events and other co-morbidities. Hence there is a need to develop an integrated preventive and therapeutic approach for both these conditions and not treat them as separate entities. [ABSTRACT FROM AUTHOR]

Purpose : To evaluate the effectiveness of rabeprazole and other proton pump inhibitors (PPIs) in providing symptomatic relief in patients with varying severity of gastroesophageal reflux disease (GERD). Methods : In this multicenter retrospective study, electronic medical records (EMRs) of GERD patients prescribed with PPIs at two Indian clinics/hospitals were reviewed (2016-2020). Rabeprazole's effectiveness was assessed at different follow-up visits and compared with other PPIs. Results : Overall, 269 patients (moderate and severe GERD: 84.39%) were included in three groups, viz rabeprazole, pantoprazole, and esomeprazole groups. A significant proportion of patients experienced quick and complete symptomatic relief at visit 1 with rabeprazole compared to the baseline visit, which gradually increased till visit 4 for both daytime [ viz heartburn (38.78-93.88%; p < 0.001)] and nocturnal symptoms [ viz sleep disturbances (62.92-97.75%; p < 0.001)]. Rabeprazole provided quick relief at visit 1 when compared with pantoprazole for daytime heartburn (38.78 vs 5.56%; p = 0.01), daytime epigastric pain (66.04 vs 12.12%; p = 0.049), and nocturnal water brash (60.71 vs 16.13%; p = 0.015), and when compared with esomeprazole for nocturnal nausea (82.61 vs 20.00%; p = 0.013). Further, the proportion of patients exhibiting complete treatment response was relatively higher in the rabeprazole group (83.33%) than in the pantoprazole (62.07%) and esomeprazole (65.67%) groups at visit 4. Conclusion : Rabeprazole was effective in providing quick and sustained relief for both daytime and nocturnal GERD symptoms in patients with moderate and severe GERD. Rabeprazole also demonstrated greater effectiveness when compared with pantoprazole and esomeprazole in reducing the severity of multiple GERD symptoms.
