Objective: The purpose of this study was to investigate the characteristics and infection control practices of dentists in Mexico City in relation to their willingness to treat AIDS/HIV-positive patients.
Study Design: The population study encompassed Mexico City dentists who were selected according to a geographic criterion. A questionnaire was delivered personally to each participant, and multiple logistic regression was used for data analysis.
Results: A total of 598 dentists participated in the study. The response rate was 99.3% (598/602). Seventy-four percent (444) of the dentists said they would be willing to treat AIDS/HIV-positive patients. Among the variables associated with the prediction of willingness to treat these patients were glove-wearing patterns (odds ratio, 2.39; confidence interval, 1.4-4.2), types of available sterilization equipment (odds ratio = 2.42; confidence interval, 1.4-4.1), fear of losing non-AIDS/HIV-positive patients (odds ratio = 4.28; confidence interval, 2.3-8.4), and risk perception of HIV transmission (odds ratio = 2.66; confidence interval, 1.5-4.9). An interaction was found between perception of risk of HIV transmission and increase in costs (odds ratio = 3.35; confidence interval, 1.3-8.9).
Conclusions: Approximately 26% of the Mexico City dentists included in the study were not willing to treat AIDS/HIV-positive patients. Educational programs aimed at misperceptions appear to be warranted.

Smartphone-Based Applications for Atrial Fibrillation Detection: A Systematic Review and Meta-Analysis of Diagnostic Test Accuracy.

Atrial fibrillation (AF) burden is strongly associated with an increased risk of stroke, which, in most cases, can be prevented through earlier detection of AF and the timely initiation of anticoagulation therapy. Smartphone devices can provide a simple, non-invasive, cost-effective early AF detection solution. PubMed, Embase, and Scopus databases were searched for studies comparing smartphone-based photoplethysmography (PPG) with standard electrocardiogram for AF detection.

Importance: Ultraprocessed foods (UPF), characterized as shelf-stable but nutritionally imbalanced foods, pose a public health crisis worldwide. In adults, UPF consumption is associated with increased obesity risk, but findings among children are inconsistent.
Objectives: To examine the associations among UPF intake, anthropometric adiposity indicators, and obesity status in Canadian children.
Proteomic Analyses in COVID-19-Associated Secondary Hemophagocytic Lymphohistiocytosis.

Center for Fundamental Immunology, Benaroya Research Institute, Seattle, WA.
Context: COVID-19 has been associated with features of a cytokine storm syndrome with some patients sharing features with the hyperinflammatory disorder, secondary hemophagocytic lymphohistiocytosis (sHLH).
Hypothesis: We hypothesized that proteins associated with sHLH from other causes will be associated with COVID-sHLH and that subjects with fatal COVID-sHLH would have defects in immune-related pathways.
Methods And Models: We identified two cohorts of adult patients presenting with COVID-19 at two tertiary care hospitals in Seattle, Washington in 2020 and 2021.
Pharmacovigilance analysis of drug-induced hypofibrinogenemia using the FDA Adverse Event Reporting System.

Background: Drug-induced hypofibrinogenemia has received increasing scrutiny; however, the specific drugs involved remain poorly characterized. Hypofibrinogenemia can have significant clinical implications, including increased bleeding risks.
Aim: This study aimed to utilize the FDA Adverse Event Reporting System (FAERS) to identify and analyze drugs frequently implicated in drug-induced hypofibrinogenemia.

Objective: To investigate the prognostic value of maternal angiogenic factors in late-onset small fetuses, alone or in combination with the ultrasound and Doppler parameters currently used for the classification of low-risk small-for-gestational-age (SGA) fetuses or high-risk fetal growth restriction (FGR), overall and according to the presence or absence of pre-eclampsia.
Methods: This was a prospective cohort study of women with a singleton pregnancy with a diagnosis of late-onset fetal smallness (defined as birth weight < 10 centile) and a gestational age of ≥ 34 weeks at delivery. Ultrasound assessment of estimated fetal weight (EFW) and Doppler assessment of uterine artery pulsatility index (UtA-PI) and cerebroplacental ratio (CPR) were performed every 1-2 weeks.
