Comparative effects of furosemide and other diuretics in the treatment of heart failure: a systematic review and combined meta-analysis of randomized controlled trials.

Diuretics have an essential role in the management of heart failure (HF). However, each drug has its own benefit and side effect. Side effects include fluid, electrolyte abnormalities, and acid-base disturbance. These adverse effects of diuretics predispose patients to serious cardiac arrhythmias and may increase the risk of arrhythmic mortality. Herein, we aim to summarize the relative efficacy and safety of all available diuretics used in the treatment of patients with HF. In June 2017, a systematic electronic database search was conducted in nine databases. All randomized controlled trials (RCTs) comparing the different diuretics used in HF were included for meta-analysis. The protocol was registered in Prospero with CRD42018084819. Among the included 54 studies (10,740 patients), 34 RCTs were eligible for quantitative network meta-analysis (NMA) and traditional meta-analysis while the other 20 studies were qualitatively analyzed. Our results showed that azosemide and torasemide caused a significant reduction in brain natriuretic peptide (BNP) level. Torasemide also caused a significant decrease in collagen volume fraction (CVF) and edema. No significant difference between the agents concerning glomerular filtration rate (GFR), water extraction, and sodium excretion was demonstrated. Regarding side effects, no significant difference among diuretics was observed in terms of hospital readmission and mortality rates. Diuretics are the main treatment of hypervolemia in HF patients. The choice of appropriate diuretic is essential for successful management and is mainly guided by patient clinical situations and the presence of other co-morbidities.

Valvular involvement in granulomatosis with polyangiitis: Case report and systematic review of literature.

BACKGROUND: Granulomatosis with polyangiitis (GPA) is a systemic inflammatory condition; however, patients with GPA rarely experience endocardial valve lesions. METHODS: We report a GPA case with tricuspid valve destruction together with a systematic review to highlight the characteristics of all previously reported GPA cases with valvular involvement. RESULTS: Among 36 cases included, the aortic valve was involved in 15 (41.7%) cases while the mitral valve was involved in 9 (25%) subjects. Combined lesion of both aortic and mitral valves was reported in 9 (25%) patients. CONCLUSION: We recommend routine echocardiography examination to rule out any cardiac valve lesion once GPA is suspected.

Predictors of Pathological Gastroesophageal Reflux among Emirati Patients with Reflux Symptoms Who Undergo Wireless pH Monitoring.

Background: Diagnosis of gastroesophageal reflux disease (GERD) relies on recognizing symptoms of reflux and mucosal changes during esophagogastroduodenoscopy. The desired response to acid suppression therapy is reliable resolution of GERD symptoms; however, these are not always reliable, hence the need for pH testing in unclear cases. Our objective was to identify potential predictors of a high DeMeester score among patients with potential GERD symptoms to identify patients most likely to have pathological GERD. Methods: We conducted a retrospective case-control study on patients who underwent wireless pH monitoring from January 2020 to April 2022. Cases were patients with a high DeMeester score (more than 14.7), indicating pathological reflux, and controls were those without. We collected clinical and demographic data, including age, sex, body mass index (BMI), smoking status, non-steroidal anti-inflammatory drugs (NSAIDs) use, and presence of atypical symptoms. Results: 86 patients were enrolled in the study. 46 patients with high DeMeester scores were considered cases, and 40 patients with DeMeester scores less than 14.7 were considered controls. Esophagitis (grade A) was found in 41.1% of the cases and in 22.5% of the control group. In our study, age of more than 50 years compared with age of 20-29 years and being overweight appeared to be predictors of true pathological reflux among patients with reflux symptoms who underwent wireless pH monitoring. Conclusion: Age above 50 years compared with age between 20-29 years and being overweight appeared to be predictors of true pathological reflux among patients with reflux symptoms who underwent wireless oesophageal pH monitoring. The presence of oesophagitis was approximately four times more likely to be associated with true pathological reflux.

Safety and efficacy of adipose-derived mesenchymal stem cells for knee osteoarthritis: A systematic review and m-analysis.

OBJECTIVE: This research aimed to study the safety and efficacy of adipose-derived mesenchymal stem cells (ADMSCs) for knee osteoarthritis (OA). METHODS: We used six databases to search for records and then screened them for eligibility. In both randomized and non-randomized studies, the risk of bias was assessed. The data were then retrieved and used in single-arm and double-arm analyses using Comprehensive Meta-Analysis (CMA) Version 3.0 and RevMan Version 5.3, respectively. RESULTS: Based on the study's inclusion criteria, we included 15 studies with a total of 463 patients. According to our single-arm analyses, there was a significant improvement in quality of life (QOL) among the three dose subgroups (high, medium, and low doses), as measured by SF-36 scores after a year of follow-up [low dose: mean (M)=-23.99; 95% confidence interval (CI) [-31.49 to -16.49]; P<0.001; medium dose: M=-15.96; 95% CI [-23.5 to-8.42]; P<0.001; high dose: M=-19.31; 95% CI [-28.02 to -10.59], P<0.001] and the knee injury and osteoarthritis outcome score (KOOS) QOL sub-score after six months following ADMSCs injection in the low-dose group (M=24.9; 95% CI [4.3 to 45.6]; P<0.05). Moreover, after three months of follow-up, we detected significant pain reduction as measured by the numeric pain rating scale (NPRS), with no significant difference between the low and medium doses (low dose: M=-3.12; 95% CI [-5.09 to -1.14]; P<0.01; medium dose; M=-2.17; 95% CI [-3.13 to -1.21]; P<0.001). However, after a year, the results were no longer significant. Despite finding no significant difference between them after 6 and 12 months post-treatment in the Visual Analogue scale (VAS) scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score, double-arm analyses revealed significant pain reduction in the ADMSCs group over the control after 12 months as estimated by the WOMAC pain sub-score (mean difference (MD)=-1.85, 95% CI [-3.55, -0.15], P<0.05). After six months, the low dosage group's knee functions and activity levels improved significantly, as determined by the WOMAC physical function and stiffness subscales (M=-23.79; 95% CI [-38.43 to -9.16]; P=0.001; M=-10.25; 95% CI [-17.31 to -2.59]; P<0.01, respectively), as well as the KOOS scores after a year (P<0.01 for all KOOS subscales). In the ADMSCs injections group, there were no serious adverse effects [event rate (ER)=0.11; 95% CI [0.03-0.3]; P=0.001]. CONCLUSION: In the present single-arm meta-analysis, ADMSCs were associated with significant reduction in pain and improvement in QOL and knee functions in patients with knee OA. However, double arm analyses did not confirm these positive findings, which may be returned to the small sample size of included patients. Therefore, to introduce ADMSCs into clinical practice and establish guidelines for their use, more randomized controlled clinical trials with large sample sizes and long-term follow-ups are needed.
