Subjective sleep quality before and during the COVID-19 pandemic in a Brazilian rural population.

Objectives: Prior studies have examined sleep during the coronavirus disease 2019 (COVID-19) pandemic, but have few compared sleep measured both during and prior to COVID. We examined the impact of the COVID-19 pandemic on subjective sleep quality in general and separately by gender and age (<50 vs. ≥50 years).

Endothelial injury in COVID-19 and septic patients.

Systemic inflammatory response, as observed in sepsis and severe COVID-19, may lead to endothelial damage. Therefore, we aim to compare the extent of endothelial injury and its relationship to inflammation in both diseases. We included patients diagnosed with sepsis (SEPSIS group, n = 21), mild COVID-19 (MILD group, n = 31), and severe COVID-19 (SEVERE group, n = 24).

Lower peripheral blood Toll-like receptor 3 expression is associated with an unfavorable outcome in severe COVID-19 patients.

The role of innate immunity in COVID-19 is not completely understood. Therefore, this study explored the impact of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection on the expression of Pattern Recognition Receptors (PRRs) in peripheral blood cells and their correlated cytokines. Seventy-nine patients with severe COVID-19 on admission, according to World Health Organization (WHO) classification, were divided into two groups: patients who needed mechanical ventilation and/or deceased (SEVERE, n = 50) and patients who used supplementary oxygen but not mechanical ventilation and survived (MILD, n = 29); a control group (CONTROL, n = 17) was also enrolled.

Neuro-Ophthalmological Findings as First Manifestation of Occipital Tuberculoma.

We present a 54-year-old male garbage collector, who came to the ophthalmology department due to one-month history of bilateral blurred vision, palinopsia, headache and visual geometrical hallucinations. The examination showed a normal anterior segment, a homonymous left upper central scotoma and tilted segmental hypoplasia of the optic nerve of the left eye. Contrast-enhanced brain magnetic resonance imaging showed a mass lesion in the right occipital cortex.

Prevalence of refractive errors in Colombia: MIOPUR study.

Purpose: To determine the prevalence of refractive errors in Colombia and its relations with demographic and socioeconomic variables.

Methods: A cross-sectional study performed in 10 Colombian administrative districts (MIOPUR study), including children and adolescents from 8 to 17 years old and adults from 35 to 55 years old.

Results: 3608 individuals (100% of whom agreed to participate) were included.

Association between Dietary Intake and Coronary Artery Calcification in Non-Dialysis Chronic Kidney Disease: The PROGREDIR Study.

Coronary artery calcification (CAC) is a widespread condition in chronic kidney disease (CKD). Diet may play an important role in CAC, but this role is not clear. This study evaluated the association between macro-and micronutrient intakes and CAC in non-dialysis CKD patients.

Refractive errors in children and adolescents in Bucaramanga (Colombia).

Purpose: The aim of this study was to establish the frequency of refractive errors in children and adolescents aged between 8 and 17 years old, living in the metropolitan area of Bucaramanga (Colombia).

Methods: This study was a secondary analysis of two descriptive cross-sectional studies that applied sociodemographic surveys and assessed visual acuity and refraction. Ametropias were classified as myopic errors, hyperopic errors, and mixed astigmatism.

Age, Gender, and Race-Based Coronary Artery Calcium Score Percentiles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Background: Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. Although the population distribution of CAC has been determined for several White populations, the distribution in ethnically admixed groups has not been well established.

Hypothesis: The CAC distribution, stratified for age, gender and race, is similar to the previously described distribution in the MESA study.

Hepatotoxicity from ingestion of wild mushrooms of the genus Amanita section Phalloideae collected in Mexico City: two case reports.

We present two cases of acute liver injury resulting from consumption of wild mushrooms. The first case was a male who developed acute hepatitis after ingestion of diverse mushrooms including Amanita species. His clinical course was favorable with complete recovery of liver function.

[Case report of mucormycosis in a patient with secondary methimazole-induced agranulocytosis].

Agranulocytosis is a rare side effect of antithyroid drugs, it occurs in less than 0.5% of patients, usually during the first few months of treatment. It is considered to be the most serious adverse effect of these medications since it may be complicated by serious, life-threatening infections.

Physical activity and overweight/obesity in adult Mexican population: the Mexican National Health and Nutrition Survey 2006.

Objective: To determine the association between physical activity and overweight/obesity in Mexican adults.

Material And Methods: Cross-sectional design. Adults 20 to 69 years of age were included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006).
