Proenkephalin as a Novel Prognostic Marker in Heart Failure Patients: A Systematic Review and Meta-Analysis

Over the last several years, the use of biomarkers in the diagnosis of patients with heart failure (HF) has skyrocketed. Natriuretic peptides are currently the most widely used biomarker in the diagnosis and prognosis of individuals with HF. Proenkephalin (PENK) activates delta-opioid receptors in cardiac tissue, resulting in a decreased myocardial contractility and heart rate. However, the goal of this meta-analysis is to evaluate the association between the PENK level at the time of admission and prognosis in patients with HF, such as all-cause mortality, rehospitalization, and decreasing renal function. High PENK levels have been associated with a worsened prognosis in patients with HF

First case series and literature review of coronavirus disease 2019 (COVID-19) associated pulmonary tuberculosis in Southeast Asia: Challenges and opportunities

Background: Subclinical tuberculosis (TB) is accidentally detected by radiologic and microbiologic findings. Transmission by those with subclinical TB could delay prevention effort. However, our study demonstrated positive aspect of COVID-19 outbreak as it could allow subclinical TB to be detected faster through a chest X-Ray (CXR). Methods: This cross-sectional cohort study aimed to report demographics, comorbidities, and outcomes related to early detection of TB among COVID-19 patients, and to elaborate the association between SARS-CoV-2 and pulmonary TB. Data of patients with SARS-CoV-2 co-infection with Mycobacterium tuberculosis (MTB) diagnosed between March 2020 – March 2022 was collected. Results: Out of 12,275 COVID-19 patients, 26 were definitively diagnosed with MTB infection (mean age 48.16 ± 20.17 years). All cases that had suspicious CXR that were not typical for COVID-19, were tested for MTB. On average, pulmonary TB was diagnosed after admission 5(3−10) days, the treatment initiation period was 3(1−5) days from the TB diagnosis. Conclusions: This suggests an early detection of tuberculosis among COVID-19 patients by quicker screening CXR and sputum comparing to previous symptom guided screening. Thereby reducing the chance of TB transmission demonstrated during COVID-19 pandemic. So, clinicians should be aware of pulmonary tuberculosis in COVID-19 patients with atypical radiologic findings

Hand knob sign in osmotic demyelinating syndrome

Abstract Background Osmotic demyelinating syndrome, commonly recognized as a consequence of the rapid correction of hyponatremia, has been known to cause motor, neuropsychiatric, or extrapyramidal symptoms. We reported a patient with an unusual presentation involving bilateral hand weakness, and pseudobulbar affect. The imaging was compatible with osmotic demyelinating syndrome with bilateral hand knob lesions, despite no history of overcorrection of hyponatremia. Case presentation A 44-year-old female presented with three weeks of emotional lability, spastic dysarthria, and bilateral hand weakness following ankle surgery and a mild head injury. Physical examination revealed weakness in the intrinsic hand muscles, leading to a claw-like deformity of the hands, although sensation remained unimpaired. Magnetic resonance imaging (MRI) of the brain revealed several hyperintensities on fluid-attenuated inversion recovery imaging involving various areas, including the hand knob area of the bilateral precentral gyri, caudate, lentiform nuclei, and pons, suggestive of osmotic demyelinating syndrome. Clinical improvement was observed following a trial of intravenous pulse methylprednisolone and plasmapheresis. Conclusions Bilateral hand weakness is an unusual manifestation of osmotic demyelinating syndrome. The precentral gyrus, specifically in the hand knob area, is the vulnerable region that can result from osmotic demyelinating syndrome

Cannabis and adverse cardiovascular events: A systematic review and meta-analysis of observational studies

Background: Cannabis is the most used illicit drug in the world. Global trends of decriminalization and legalization of cannabis lead to various forms of cannabis use and bring great concerns over adverse events, particularly in the cardiovascular (CV) system. To date, the association between cannabis and adverse CV events is still controversial. Purpose: We aim to conduct a systematic review and meta-analysis to assess the adverse CV events from cannabis use. Patients and methods: A systematic search for publications describing the adverse CV events of cannabis use, including acute myocardial infarction (MI) and stroke, was performed via PubMed, Scopus, and Cochrane Library databases. Data on effect estimates in individual studies were extracted and combined via random-effects meta-analysis using the DerSimonian and Laird method, a generic inverse-variance strategy. Results: Twenty studies with a total of 183,410,651 patients were included. The proportion of males was 23.7%. The median age and follow-up time were 42.4 years old (IQR: 37.4, 50.0) and 6.2 years (IQR: 1.7, 27.7), respectively. The prevalence of cannabis use was 1.9%. Cannabis use was not significantly associated with acute MI (pooled odds ratio (OR): 1.29; 95%CI: 0.80, 2.08), stroke (pooled OR 1.35; 95%CI: 0.74, 2.47), and adverse CV events (pooled OR: 1.47; 95%CI: 0.98, 2.20). Conclusion: The risk of adverse CV events including acute MI and stroke does not exhibit a significant increase with cannabis exposure. However, caution should be exercised when interpreting the findings due to the heterogeneity of the studies

Knowledge regarding human papillomavirus and cervical cancer prevention among medical students from Chulalongkorn University in Thailand

Abstract Background Cervical cancer is one of the leading causes of death among women in Thailand. General practitioners, within their primary healthcare role, play a vital role in the cervical cancer screening program, as they are the healthcare professionals most easily accessible to the general population. This study aims to determine the level of knowledge of cervical cancer and human papillomavirus (HPV) infection, HPV vaccination, and cervical cancer screening among last-year medical students. Methods A cross-sectional study was conducted among sixth-year medical students using an electronic self-administered questionnaire. The two-part questionnaire comprised demographic data and 12 true/false questions that assessed knowledge regarding HPV infection, HPV vaccination, and cervical cancer screening recommendations. Pilot testing revealed a high Cronbach’s alpha and test–retest reliability coefficient. Results A 67% response rate was achieved. Among the 198 respondents, only one (0.5%) student correctly answered over 80% of the questions while most respondents (172, 71.7%) correctly answered less than 60% of the questions. Less than half of the respondents correctly identified crucial aspects such as the primary cause of cervical cancer, recommended vaccination age, cytology sensitivity compared to HPV testing, and the recommended screening frequency for average-risk women. Conclusions This study highlights a significant lack of comprehension among Thai medical students concerning HPV infection, vaccination, and cervical cancer screening guidelines. Encouraging educational enhancement, effective communication, and heightened awareness of these crucial topics within the medical school curriculum are imperative
