Predictors of gastrointestinal bleeding in patients following left ventricular assist device implantation: a systematic review and meta-analysis.

Aim: Our study aims to provide a more holistic understanding of the available data and predictive risk factors for gastrointestinal bleed (GIB). Materials & methods: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials and Web of Science Core Collection and calculated relative risk and meta-regression was utilized to evaluate for risk factors in order to assess the effect of covariates. Results: Our meta-analysis reported a pooled prevalence rate of GIB of 24.4%. Meta-regression analysis did not yield a statistically significant association between GIB and risk factors, including age, gender, hypertension, chronic kidney disease and diabetes. Conclusion: Studies investigating larger sample sizes are required for conclusive findings.

Health and Immune Boosting Techniques of General Adult Pakistani Population: A KAP Study.

OBJECTIVE: To discover Pakistani adult population's perception about their general health, immune status and knowledge regarding immunity, and to highlight their efforts to improve it. METHODS: The knowledge-attitude-practice study was conducted from January to May 2021, after approval ethics review committee of the Islamic International Medical College, Rawalpindi, Pakistan, and comprised individuals of either gender from the community aged 18 years or more and not suffering from any physical disability or mental illness. Data was collected using a pre-tested, self-administered questionnaire that was disseminated through online platforms. The collected data was analysed using SPSS 25. RESULTS: All the 455(100%) individuals approached responded to the questionnaire. The mean age of the subjects was 22.6±7.579 years. There were 256(56.3%) female respondents, 283(62.2%) were aged 20-21 years, and 359(78.9%) hailed from the Sindh province. Most participants perceived their general health as 'good' 197(43.3%). The immune system function was reported 'good' by 200(44%), and the perception of general knowledge of immunity was reported 'good' by 189(41.5%) subjects. Inverse relationships were identified between stress levels and self-perceived health, and between receiving effective homeopathic treatment and 'very good' self-perceived immune status (p<0.05). People willing to take non-obligatory vaccines had a positive opinion about their self-perceived knowledge on immunity that produced a direct relationship (p<0.05). CONCLUSIONS: The findings provide a framework of practices that should be promoted to improve health status of adult population in Pakistan.
