Background: Despite declining COVID-19 incidence, healthcare workers (HCWs) still face an elevated risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. We developed a diagnostic multivariate model to predict positive reverse transcription polymerase chain reaction (RT-PCR) results in HCWs with suspected SARS-CoV-2 infection.

Methods: We conducted a cross-sectional study on episodes involving suspected SARS-CoV-2 symptoms or close contact among HCWs in Bogotá, Colombia.

Article Synopsis
  • The study aimed to explore how non-drug treatments affect sarcopenic obesity (SO) through a meta-analysis of randomized controlled trials (RCTs).
  • Results indicated that exercise and nutrition can improve various physical health metrics, such as body fat percentage (PBF) and grip strength, but individual interventions showed limited effectiveness.
  • The combination of exercise and nutritional interventions proved to be the most effective approach for improving outcomes related to SO, highlighting the potential role of physical therapy as well.

Since the COVID-19 pandemic, considerable advances have been made to improve epidemic preparedness by accelerating diagnostics, therapeutics, and vaccine development. However, we argue that it is crucial to make equivalent efforts in the field of outbreak analytics to help ensure reliable, evidence-based decision making. To explore the challenges and key priorities in the field of outbreak analytics, the Epiverse-TRACE initiative brought together a multidisciplinary group of experts, including field epidemiologists, data scientists, academics, and software engineers from public health institutions across multiple countries.

Article Synopsis
  • Recent studies highlight the advantages of using intravascular imaging (IVI) for percutaneous coronary intervention (PCI) compared to traditional angiography, but the relevance of angiography-based physiological assessments during this procedure is not fully understood.
  • The FLAVOUR trial analyzed the impact of angiography-based physiological evaluations, specifically the quantitative flow ratio (μQFR), on treatment decisions for patients undergoing IVI-guided PCI.
  • Results indicated significant reclassification of treatment approaches based on μQFR, with the REFERENCE group experiencing a higher risk of major adverse cardiovascular events, while DEFER and PERFORM groups showed similar outcomes and quality of life after 2 years.*

Preserved motion perception and the density of cortical projections to V5 in homonymous hemianopia.

Brain Commun

December 2024

Division of Neurology, Department of Medicine, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok 10400, Thailand.

Following a unilateral post-chiasmal lesion of the geniculo-striate pathway, patients develop homonymous visual field defects. Using classical perimetry, patients with 'complete' homonymous hemianopia are unaware of stimuli in the affected hemifield. However, some show preserved vision in the affected hemifield in which the conscious perception of moving stimuli is preserved (Riddoch phenomenon).

Background: The shift in medical care toward prediction and prevention has led to the emergence of digital health care as a valuable tool for managing health issues. Aiding long-term follow-up care for cancer survivors and contributing to improved survival rates. However, potential barriers to mobile health usage, including age-related disparities and challenges in user retention for commercial health apps, highlight the need to assess the impact of patients' abilities and health status on the adoption of these interventions.

Department of Clinical Epidemiology and Biostatistics, National Clinical Research Center for Child Health and Disorders, Ministry of Education Key Laboratory of Child Development and Disorders, Chongqing Key Laboratory of Pediatric Metabolism and Inflammatory Diseases, Children's Hospital of Chongqing Medical University, 136 2nd Street, Yuzhong District, Chongqing, 400014, China.

A limited number of cohort studies have explored the impact of serum essential metal elements on blood pressure (BP) or glycolipids and their regulatory mechanism in children. This study aimed to investigate the relationship between serum metal concentrations of iron (Fe), zinc (Zn), calcium (Ca), copper (Cu), and magnesium (Mg) and BP in children, and explore the potential mediating effects of glycolipid profiles. This cohort study included 1993 children (3566 BP measurements) aged 6-14 years in Chongqing, China.

Objective: Electroencephalographic seizures (ES) are common in neonates with hypoxic-ischemic encephalopathy (HIE), but identification with continuous electroencephalographic (EEG) monitoring (CEEG) is resource-intensive. We aimed to develop an ES prediction model.

Methods: Using a prospective observational study of 260 neonates with HIE undergoing CEEG, we identified clinical and EEG risk factors for ES, evaluated model performance with area under the receiver operating characteristic curve (AUROC), and calculated test characteristics emphasizing high sensitivity.

Article Synopsis
  • Bariatric surgery is a treatment option for obese patients who cannot lose weight through non-surgical methods, but it is expensive; this study evaluates its cost-effectiveness against nonbariatric surgery for patients with a BMI ≥32.5 kg/m2 and type 2 diabetes in Thailand.
  • A Markov model was used to analyze lifetime costs and quality-adjusted life years (QALYs) from both payer and societal perspectives, showing that bariatric surgery has higher costs but also more QALYs gained compared to nonbariatric surgery.
  • The study concluded that bariatric surgery is cost-effective with an incremental cost-effectiveness ratio (ICER) below the cost-effectiveness threshold of 160,000 baht/Q

Risk of Hypoglycemia Associated with Concomitant Use of Insulin Secretagogues and ACE Inhibitors in Adults with Type 2 Diabetes: A Systematic Review.

Clin Pharmacol Ther

December 2024

Center for Real-World Effectiveness and Safety of Therapeutics, Center for Clinical Epidemiology and Biostatistics, and Department of Biostatistics, Epidemiology and Informatics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Insulin secretagogues and angiotensin-converting enzyme inhibitors (ACEIs) are commonly co-prescribed for patients with type 2 diabetes (T2D). Case reports suggesting that co-administration of insulin secretagogues with ACEIs is associated with an increased risk of serious hypoglycemia have led to warnings regarding a drug-drug interaction in widely used drug compendia. However, subsequent studies have had inconsistent results.
