Demographics and clinical characteristics of alcohol-related admissions in a tertiary care hospital in Qatar: Does age matter?

BACKGROUND: Alcohol consumption is a major cause of acute and chronic health conditions associated with comorbidities and traumatic injuries, despite its partial prohibition in some countries. Moreover, alcohol-related hospital admissions increase the burden on the healthcare system. More than 80% of the population in Qatar comprises expatriates. This study aimed to analyze the demographics and clinical characteristics of subjects with alcohol-related emergency department (ED) visits/hospitalization with respect to different age groups in a single tertiary hospital in Qatar. METHODS: It is a retrospective observational study of adult patients who visited the ED at Hamad General Hospital between January 2013 and March 2015 and were screened positive for alcohol use. Collected data included sociodemographic characteristics, blood alcohol concentration (BAC), pattern of admission, previous medical history, laboratory investigations, treatment, hospital course, and mortality. Data were compared with respect to the distribution of age groups such as < 25, 25-34, 35-44, 45-54, and >55 years. RESULTS: In total, 1506 consecutively admitted patients screened positive for alcohol use were included in the study; the majority of them were males (95.6%), non-Qatari nationals (71.1%), and aged 35-44 years (30.9%). The age groups 35-44 years and 45-54 years showed the highest median BAC ([0.24 interquartile range (IQR: 0.14-0.33)] and [0.24 (IQR: 0.13-0.33)], respectively) as compared to the other age groups (P = 0.001). The pattern of hospital admission, sociodemographic status, presence of comorbidities, laboratory investigations, and mortality showed specific age-related distribution. Particularly, young adults were more likely to have a previous ED visit due to trauma, whereas older patients' previous hospital admissions were mostly related to various underlying comorbidities. CONCLUSION: This study highlighted the patterns of age and clinico-epidemiological status of patients with alcohol-attributable hospital admissions. Our study showed that alcohol consumption was higher among the working-age group. Further studies are needed to investigate changes in the alcohol consumption patterns that may help plan for allocation of health resources and prevention of alcohol-related problems.

Assessing the risk of angiotensin receptor blockers on major cardiovascular events: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Angiotensin receptor blockers (ARBs) are commonly used as a treatment for many cardiovascular diseases, but their safety has been called into question. The VALUE trial found an increased risk of myocardial infarction in participants receiving ARBs compared to other antihypertensive. The aim of the meta-analysis was to synthetize the available evidence of randomised controlled trials (RCTs) and elucidate if ARBs increase the risk of cardiovascular events. METHODS: A comprehensive search was conducted to identify RCTs that assessed the safety of ARBs. Titles and abstracts of all papers were independently screened by two authors. Data extraction and quality assessment were also performed independently. The relative risk (RR) of all-cause mortality, myocardial infarction, and stroke were pooled using the IVhet model. Multiple sensitivity analyses were conducted to assess the effect of ARBs by restricting the analysis to different participants' characteristics. RESULTS: Forty-five RCTs comprising of 170,794 participants were included in the analysis. The pooled estimates revealed that ARBs do not increase the risk of all-cause mortality (RR 1.00; 95%CI 0.97-1.04), myocardial infarction (RR 1.01; 95%CI 0.96-1.06), and stroke (RR 0.92; 95%CI 0.83-1.01). The sensitivity analysis did not yield a particular group of patients at increased risk of cardiovascular events with ARBs. Risk of all-cause mortality and stroke decreased with ARB when the proportion of smokers in a population was < 25% (RR 0.91; 95%CI 0.84-0.98) and in females (RR 0.76; 95%CI 0.68-0.84), respectively. CONCLUSIONS: ARBs do not increase the risk of major cardiovascular events and are safe for use in patients.

Imported COVID-19 Cases from Iran: A Rapid Review.

This review aims to map the spread of the virus from Iran to the Middle East and the rest of the world and to help better understand the key trends that occurred during COVID-19 from this epidemic center. We performed a literature review which was undertaken from 16 June to 22 November 2020. We reviewed the available evidence on imported cases from Iran, in the electronic databases PubMed and Google Scholar, as well as gray literature. It is shown that 125 cases were imported from Iran, out of which most of the imported cases were asymptomatic, and PCR testing was the most common method of detection. It was also found that more than half of the imported cases were not quarantined or isolated at home. The review revealed that many countries, especially the Middle East had imported cases from Iran. The big gap between the date of arrival at the airport and the date of diagnosis emphasizes the importance of early detection and quarantine measures, to stop the spread of the virus.
