Therapeutic efficacy of hepatitis B virus vaccine in treatment of chronic HBV infections: A systematic review and meta-analysis.

There is a need for improved treatment of patients with chronic hepatitis B (CHB). We reviewed the literature to explore the efficacy of HB vaccines alone or in combination therapy (CT) with antiviral drugs in CHB patients and to meta-analyze data from randomized controlled trials. We conducted a systematic search in ten databases. All studies investigating the efficacy of HBV vaccine in HBV infected patients were included with no restrictions. Among 1359 studies initially identified, 23 studies (n = 1956 patients) were included for the final analysis. CT showed a significant reduction of HBV DNA compared with analogue monotherapy (AM) at the 12-month follow-up period (odds ratio (OR) = 2.835, 95% confidence interval (CI) [1.275, 6.306], p = .011). Additionally, CT also remarkably induce HbsAg loss in comparison with AM (OR = 11.736, 95% CI [1.841, 74.794], p = .009). Our pooled data revealed no difference between treatment and control regarding alanine aminotransferase normalization, HBeAg seroconversion, and HBeAg disappearance. In addition, CT using vaccine and NAs resulted in a statistically significant higher incidence of adverse effects than AM. The therapeutic effects of combination therapy for patients with CHB were encouraging, but future studies need to investigate all possible treatment combinations and assess their cost-effectiveness.

Semaglutide for the treatment of type 2 Diabetes Mellitus: A systematic review and network meta-analysis of safety and efficacy outcomes.

BACKGROUND AND AIMS: To assess the safety and efficacy of semaglutide compared with placebo and other anti-hyperglycaemic agents in type 2 diabetes (T2DM). METHODS: We searched PubMed, Scopus, Web of Science, and Cochrane library for relevant randomized controlled trials (RCTs). A network meta-analysis was conducted to compare different doses, durations, and interventions in T2DM. We presented results as mean difference (MD) or relative risk (RR) and 95% confidence interval (CI). RESULTS: Twenty-six included RCTs studied different doses of subcutaneous (SC) and oral semaglutide, tirzepatide, liraglutide, sitagliptin, canagliflozin, and empagliflozin compared with placebo. Tirzepatide showed the highest efficacy, however, it was comparable to semaglutide. SC semaglutide 1 mg once-weekly showed higher reduction in HbA1c (MD = -1.72, 95% CI [-2.32; -1.12]), and fasting blood glucose (MD = -1.93, 95% CI [-2.81; -1.04]) versus placebo at 30 weeks and other timepoints. Adverse events (ADs) were comparable to placebo with oral and SC semaglutide, oral sitagliptin, SC liraglutide, and oral empagliflozin at most timepoints. However, SC semaglutide 0.8 mg and tirzepatide 10 mg groups had the highest gastrointestinal adverse events. CONCLUSION: Tirzepatide, oral and SC semaglutide has a favourable efficacy in treating T2DM. The adverse events were comparable to placebo; however, gastrointestinal adverse events were highly recorded in tirzepatide, oral and SC semaglutide groups.

Awareness of Rheumatic Heart Disease in Egypt: A National Multicenter Study.

BACKGROUND: While the prevalence of rheumatic heart disease (RHD) in Egypt is relatively high, data on the awareness of Egyptians about the cause of RHD are lacking. METHODS: Using a pre-tested questionnaire, we performed a multicenter survey of outpatients attending 15 university hospitals across Egypt. RESULTS: A total of 6958 participants were interviewed. Most subjects (81.7%) reported a previous experience of sore throat. Seeking treatment, most patients (69.3%) consulted a medical professional, while the others relied on self/peer medication. Individuals consulting a physician received antibiotics more frequently than those who did not (89.1 vs. 38.7%; OR: 12.4, 95% CI 10.8-14.1). The median RHD knowledge score in our sample was 4 (IQR = 6). While most subjects (56.3%) claimed knowledge of the complications of an untreated sore throat, only a third (34%) were aware of the association between sore throat and RHD. In a multivariate analysis, older age (Mean Difference [MD]: 1.58, 95% CI 1.37-1.79), female gender (MD: 0.89, 95% CI 0.75-1.04), higher education (MD: 1.10, 95% CI 0.90-1.30), and being interviewed outside Cairo (MD: 0.67, 95% CI 0.51-0.82) were significant predictors of knowledge about RHD. CONCLUSION: The current study showed low levels of awareness on the cause of RHD among Egyptians and highlights a pressing need for interventions to address this public knowledge gap.

Using the primary site as a prognostic tool for nodal mantle cell lymphoma: a SEER-based study.

Background: Nodal mantle cell lymphoma (NMCL) has a worse survival than extra-nodal mantle cell lymphoma. Materials & methods: A cohort study was conducted to evaluate the primary site role as a mortality predictor using data from 1983 to 2011 from the Surveillance, Epidemiology, and End Results (SEER) database. Results: Most patients had NMCL in multiple regions (71.9%). There was a significantly increased incidence of NMCL cases over years with 83.2% of them occurred between 1998 and 2011. The mean survival was 52.9 months with overall survival/cancer-specific survival rate of 29.2/42.9%, respectively. Lymph nodes of intrathoracic and multiple regions had a worse overall survival while the head, face and neck, intra-abdominal, pelvic, inguinal region and leg as well as multiple regions had worse cancer-specific survival. Conclusion: NMCL primary site can serve as a prognostic factor. We encourage adding it to MCL International Prognostic Index.

The effect of inhalation aromatherapy in patients undergoing cardiac surgery: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The goal of this study was to synthesize evidence regarding the efficacy of inhalation aromatherapy in patients undergoing cardiac surgery. METHODS: We conducted an electronic search of four authentic databases. Randomized controlled trials (RCTs), which compared inhalation aromatherapy versus control in patients undergoing cardiac surgery, were included. Data were extracted from eligible studies and pooled in a meta-analysis model. We sought to evaluate anxiety, pain, stress, and vital signs including heart rate, systolic and diastolic blood pressure. RESULTS: Nine RCTs were included in this study with a total of 656 patients. Our analysis showed inhalation aromatherapy was significantly effective in reducing anxiety (MD= -3.11, 95 % CI [-5.26, -0.96], p = 0.005), and pain (MD= -0.83, 95 % CI [-1.59, -0.07], p = 0.03) in patients undergoing cardiac surgery. Additionally, inhalation aromatherapy significantly reduced heart rate compared to control group (MD= -5.49, 95 % CI [-9.07, -1.81], p = 0.003). However, no significant differences were found between both groups in mental stress, systolic and diastolic blood pressure. CONCLUSION: Inhalation aromatherapy administration especially with lavender can significantly reduce anxiety, pain, and heart rate in patients performed cardiac surgery. However, it is not associated with significant differences in systolic and diastolic blood pressure. Further studies are needed to confirm our results.

Association of breastfeeding status with risk of autism spectrum disorder: A systematic review, dose-response analysis and meta-analysis.

Current evidence indicates that nutritional status in newborns, especially the duration of breastfeeding, plays a key role in the pathogenesis of autism spectrum disorder. We aimed to systematically review and meta-analyze relevant studies with findings of an association between autism spectrum disorder and breastfeeding patterns, and undertook an extensive dose-response analysis to interpret the results more accurately. Ten electronic databases and manual search of reference lists were used to identify relevant studies in September 2018. Dose-response and conventional meta-analysis were conducted by the random-effects model. The study protocol was registered in PROSPERO with CRD42016043128. Seven case-control studies were found in which the association between ever breastfeeding and risk of autism spectrum disorder was investigated. We found a 58 % decrease in the risk of autism spectrum disorder with ever breastfeeding and a 76 % decrease in the risk with exclusive breastfeeding. According to our dose-response meta-analysis, breastfeeding for 6 months was associated with a 54 % reduction in the risk. In the conventional meta-analysis, breastfeeding for 12-24 months was associated with the most significant reduction in the risk of autism spectrum disorder. Our results highlight the importance of breastfeeding to decrease the risk of autism spectrum disorder.

Systematic review and meta-analysis of randomized controlled trials of atosiban versus nifedipine for inhibition of preterm labor.

BACKGROUND: Two tocolytic drugs-atosiban and nifedipine-are currently used for first-line treatment of preterm labor (PTL). OBJECTIVE: To compare the efficacy and safety of atosiban with nifedipine for PTL treatment. SEARCH STRATEGY: In May 2017, we searched PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Clinical Trials with search terms including "nifedipine", "atosiban", and "preterm labor". SELECTION CRITERIA: Randomized controlled trials of women with PTL. DATA COLLECTION AND ANALYSIS: Data were extracted for study design, patient characteristics, risk of bias domains, and study outcomes. A random-effects model was used to generate pooled risk ratios (RRs) and 95% confidence intervals (CIs). RESULTS: We included seven studies that enrolled 992 patients. There was no significant difference between atosiban and nifedipine for pregnancy prolongation of 48 hours or more regarding efficacy (RR 1.06, 95% CI 0.92-1.22; P=0.440) or effectiveness (0.93, 0.84-1.03; P=0.177). Pregnancy prolongation for 7 days or more also did not differ between groups for efficacy (RR 1.04, 95% CI 0.89-1.21; P=0.656) or effectiveness (0.91, 0.79-1.05; P=0.177). Atosiban-however-was associated with fewer maternal side-effects than nifedipine. CONCLUSION: Atosiban resulted in fewer maternal side-effects than nifedipine, with no difference in pregnancy prolongation. PROSPERO registration: CRD42018090223.
