Background: The use of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) in patients with coronavirus disease 2019 (COVID-19) given their interaction with the angiotensin-converting enzyme-2 (ACE-2) receptor remains controversial. .
Objective: To investigate the impact of ACEI/ARB on COVID-19 disease severity and mortality through a systematic review and meta-analysis.
Methods: We searched PubMed and CINAHL databases as well as pre-print servers for studies investigating usage of ACEIs/ARBs in patients with COVID-19 compared to a control group of COVID-19 patients without ACEI/ARB use. COVID-19 related severity of disease, and death were identified as end points. Pooled odds ratios (OR) and their 95% confidence intervals (CI) were calculated using random-effects model.
Results: 21 studies were included in the meta-analysis. For mortality with ACEI/ARB use, the pooled odds ratio was 1.29 [0.89-1.87] p = 0.18 with heterogeneity of 91%, while the pooled OR for COVID-19 severity was 0.94 [0.59-1.50] p = 0.81 with heterogeneity of 89% (Figure 2). In combining both mortality and severe disease outcomes, the pooled odds ratio was 1.09 [0.80-1.48] p = 0.58 but with heterogeneity of 92%.
Expert Opinion: Even on pooled analysis of both un-adjusted data, adjusted data(studies with matched controls) and taking into account factors such as risk of bias of studies via meta regression and sensitivity analyses, the results hold true that ACEI/ARB use is not associated with COVID-19 disease severity or mortality. To look for any potential beneficial effects, randomized controlled trials are needed.
Conclusion: use of ACEI/ARB was not associated with increased mortality or severe COVID-19.

Sodium-glucose cotransporter 2 inhibitors and outcomes in transthyretin amyloid cardiomyopathy: Systematic review and meta-analysis.
Eur J Clin Invest
January 2025
Second Department of Cardiology, Hippokration General Hospital, Aristotle University of Thessaloniki, Thessaloniki, Greece.
Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) commonly leads to heart failure but has traditionally been an exclusion criterion in randomized clinical trials (RCTs) of sodium-glucose cotransporter 2 inhibitors (SGLT2i); therefore, the effects of these drugs in this population remain undocumented. In light of recent studies, this meta-analysis aimed to investigate the effect of SGLT2i on the prognosis of patients with ATTR-CM.
Methods: A comprehensive search of Medline, Scopus, and the Cochrane Library was conducted up to November 17, 2024.
Differences in the effectiveness of individual-level smoking cessation interventions by socioeconomic status.
Cochrane Database Syst Rev
January 2025
Nuffield Department of Primary Care Health Sciences, University of Oxford, Oxford, UK.
Background: People from lower socioeconomic groups are more likely to smoke and less likely to succeed in achieving abstinence, making tobacco smoking a leading driver of health inequalities. Contextual factors affecting subpopulations may moderate the efficacy of individual-level smoking cessation interventions. It is not known whether any intervention performs differently across socioeconomically-diverse populations and contexts.

Background: Xerostomia, or dry mouth, is a common and debilitating symptom in patients with Sjögren's syndrome, affecting their quality of life. Although Cevimeline, a muscarinic agonist, has been investigated as a potential treatment, its efficacy and optimal dosage remain uncertain. This study aims to assess the effectiveness of Cevimeline in relieving xerostomia in patients with Sjögren's syndrome by a meta-analysis of randomized clinical trials (RCT).

This meta-analysis investigates the potential of allopurinol to prevent contrast-induced nephropathy (CIN), a common and serious complication of percutaneous coronary intervention (PCI). CIN is particularly prevalent among high-risk populations, including patients with chronic kidney disease (CKD) or acute coronary syndrome (ACS), where the administration of contrast agents can exacerbate renal injury. Allopurinol, a xanthine oxidase inhibitor, is known for its dual action in reducing oxidative stress and uric acid production, positioning it as a promising therapeutic candidate to mitigate CIN.

Objective: Fetal cerebellar abnormalities are associated with neurodevelopmental disorders and structural brain malformations. Accurate and early diagnosis is crucial for prenatal counseling and planning postnatal interventions. While prenatal ultrasound is a key tool for detecting fetal brain abnormalities, variations in diagnostic accuracy across studies necessitate a systematic evaluation of its effectiveness in diagnosing cerebellar abnormalities.
