ABSTRACT
AIMS: The aim was to perform an umbrella review to summarise the existing evidence on proton-pump inhibitor (PPI) use and adverse outcomes and to grade the certainty of evidence. METHODS: Electronic databases were searched up to July 2021 for meta-analyses of cohort studies and/or randomised controlled trials (RCTs). Summary effect sizes from a random-effects model, between-study heterogeneity, 95% prediction interval, small-study effect, excess significance and credibility ceilings were devised to classify the credibility of evidence from meta-analyses of cohort studies, whereas the GRADE approach was used for meta-analyses of RCTs. RESULTS: In meta-analyses of cohort studies, 52 of the 91 examined associations were statistically significant (P ≤ .05). Convincing evidence emerged from main analysis for the association between PPI use and risk of all-site fracture and chronic kidney disease in the elderly population. However, none of these associations remained supported by convincing evidence after sensitivity analyses. The use of PPI is also associated with an increased risk of mortality due to COVID-19 infection and other related adverse outcomes, but the quality of evidence was weak. In meta-analyses of RCTs, 38 of the 63 examined associations were statistically significant. However, no associations were supported by high or moderate-quality evidence. CONCLUSION: This study's findings imply that most putative adverse outcomes associated with PPI use may not be supported by high-quality evidence and are likely to have been affected by underlying confounding factors. Future research is needed to confirm the causal association between PPI use and risk of fracture and chronic kidney disease.

BACKGROUND &OBJECTIVES: Though there are studies to evaluate the effectiveness of blended learning in pharmacy education, most of them originate from USA and have used previous year students' scores as control. Also there is less research in comparing use of self -regulated learning strategies between blended and other learning strategies. Primary aim was to evaluate the effectiveness of blended learning on knowledge score using clinical research modules. Secondary objective was designed to compare the use of self-regulated learning strategies between blended learning, web-based e-learning and didactic teaching. MATERIALS AND METHODS: A prospective cluster randomized trial was conducted with didactic teaching as control and web-based e-learning and blended learning as interventions. The target population was final year Pharm D students. Outcome was assessed using a validated knowledge questionnaire, a motivated strategies for learning questionnaire and a feedback form. All statistical analyses were carried out using Statistical Package for Social Science (SPSS) Version 20. RESULTS: A total of 241 students from 12 colleges completed the study. Mean knowledge score of students in blended learning group was higher than those in the didactic teaching and web- based e- learning program (64.26±18.19 Vs 56.65±8.73 Vs 52.11±22.06,p<0.001).Frequency of use of learning strategies namely rehearsal, elaboration, organization and critical thinking was statistically significantly higher in the blended learning group compared to those of didactic and web-based e-learning group (p<0.05) But there were no statistically significant difference of motivational orientations between didactic and blended learning group except strategies of extrinsic goal orientation and self-efficacy. Students preferred blended learning (86.5%) over didactic and web-based e-learning. CONCLUSION: Blended learning approach is an effective way to teach clinical research module. Students of blended learning group employed all motivational and learning strategies more often than students of the didactic and web- based e-learning groups except strategies of intrinsic goal orientation, task value, control of learning belief and help seeking.

RATIONALE & OBJECTIVE: Rodenticide poisoning, either accidental or intentional, is very common in rural India. The absence of a definite antidote made it a major concern with a high mortality rate. Therefore, this study aimed to assess the effectiveness of N-Acetyl Cysteine (NAC) in rodenticide poisoning as there are recent positive shreds of evidence on it. METHODOLOGY: A retrospective study was conducted in a tertiary care teaching hospital on patients admitted with rodenticide poisoning during a period of 2012-2017. The Fischer's exact test and relative risk were measured to analyze the outcome of treatment and risk factors, respectively. RESULTS: A total of 229 patients were enrolled in the study with a mean age of 30.04 ± 15.67 years. The suicidal attack was the major (86.0%) reason for poison consumption. The survival rate was significantly (p ≤ 0.03) higher in the NAC treatment group compared to the non-NAC group. Moreover, the majority (93.4%) of participants did not experience any adverse effects. The mean oral loading dose and maintenance dose was 7580.95 ± 2204.29 mg and 3694.53 ± 2322.58 mg, respectively. Yellow Phosphorus poisoning (Relative Risk [RR] 2.888 (1.179-7.079); p=0.020) and Time lag of ≥ 24 hours (RR 3.479 (1.137-10.645); p=0.029) were the significant risk factors for mortality. CONCLUSION: NAC is shown to have a significant survival benefit with a good safety profile among rodenticide poisoners. Further adequately powered prospective researches with more emphasis on dosing parameters are warranted for better quantification in different settings and for clinical implementation.
