Fueling the Firefighter and Tactical Athlete with Creatine: A Narrative Review of a Key Nutrient for Public Safety.

Firefighters, tactical police officers, and warriors often engage in periodic, intermittent, high-intensity physical work in austere environmental conditions and have a heightened risk of premature mortality. In addition, tough decision-making challenges, routine sleep deprivation, and trauma exacerbate this risk. Therefore, identifying strategies to bolster these personnel's health and occupational performance is critical.

Theoretical-methodological essay on gender identity information validity in epidemiological surveillance of violence.

The inclusion of the "gender identity" field in the Brazilian violence surveillance system, although representing a step forward, still has limitations that may compromise epidemiological data validity. Existing response options for victims' identities do not adequately cover the diversity of this analysis category, resulting in classification biases. Additionally, the absence of options for cisgender identities reflects an approach that naturalizes these identities, while trans identities are considered deviant and subject to surveillance.

Influence of type of household on prognosis at one year in patients ≥65 years attending hospital emergency departments in Spain. The EDEN-6 study.

Objective: To investigate whether the type of household is associated with prognosis at one year in patients ≥65 years of age discharged after medical consultation requiring emergency department care.

Methods: Data from the Emergency Department and Elder Needs (EDEN) cohort were used. This retrospective cohort included all patients ≥65 years of age seen in 52 Spanish emergency departments over one week (April 1-7, 2019) in whom the type of household was recorded and categorized as living at home alone, with relatives, with professional caregivers, or in a nursing home.

3D-Printed Cardiac Models for Fetal Counseling: A Pilot Study and Novel Approach to Improve Communication.

A fetal cardiology consultation involves using two-dimensional drawings to explain the cardiac anatomy which can result in inherent variation in how the congenital heart disease (CHD) is conveyed. In this pilot study, we incorporated three-dimensional printed (3DP) models into fetal counseling to demonstrate feasibility and evaluate the impact on parental knowledge, understanding, and anxiety. Parents with a prenatal diagnosis of a muscular ventricular septal defect (VSD) and/or coarctation of aorta were enrolled.

Effect of Flu Vaccination on Severity and Outcome of Heart Failure Decompensations.

Objective: To investigate the relationship of seasonal flu vaccination with the severity of decompensation and long-term outcomes of patients with heart failure (HF).

Methods: We analyzed 6147 consecutively enrolled patients with decompensated HF who presented to 33 Spanish emergency departments (EDs) during January and February of 2018 and 2019, grouped according to seasonal flu vaccination status. The severity of HF decompensation was assessed by the Multiple Estimation of Risk Based on the Emergency Department Spanish Score in Patients With Acute Heart Failure (MEESSI-AHF) + MEESSI scale, need of hospitalization and in-hospital all-cause mortality.

[Revisit after discharge from the emergency department in a cohort of patients with COVID-19 pneumonia and analysis based on the healthcare resource used for follow-up. RESALSEVID study].

Introduction: COVID-19 pneumonia is a manifestation of SARS-CoV-2 infection and in most cases involves hospital admission. There are recommendations according to which these patients can be discharged without hospital admission, but there is no evidence regarding the revisit and the most appropriate type of follow-up. The objective of the RESALSEVID study was to investigate the variables associated with the 30-day revisit (Rev30d) in a group of patients discharged directly from 4 emergency departments (ED) with COVID-19 pneumonia, and analyze whether there were differences based on 4 different tracking devices.

Effect of income on the cumulative incidence of COVID-19: an ecological study.

Objective: to analyze the relationship between per capita income and the cumulative incidence of COVID-19 in the neighborhoods of the city of Rio de Janeiro, RJ, Brazil.

Method: an ecological study using neighborhoods as units of analysis. The cumulative incidence rate per 100,000 inhabitants and the median of potential confounding variables (sex, race, and age) were calculated.

180-Day functional decline among older patients attending an emergency department after a fall.

Objectives: To determine functional changes and factors affecting 180-day functional prognosis among older patients attending a hospital emergency department (ED) after a fall.

Study Design: Retrospective analysis from a prospective cohort study (FALL-ER Registry) spanning one year that included individuals aged ≥65 years attending four Spanish EDs after a fall. We collected 9 baseline and 6 fall-related factors.

Characteristics and outcomes of older adults presented to Spanish emergency departments after a fall.

Purpose: To study patient profile, fall-related characteristics and immediate outcomes according to age and to determine the effect of age in the outcomes among older patients presenting to ED after a fall.

Methods: Cross-sectional analysis of the FALL-ER registry that included patients aged ≥ 65 years old that presented to five Spanish EDs after a fall. Patients were classified into three age categories, and demographic, comorbidity, chronic medication, fall-related characteristics, health care resources and immediate outcomes data were analysed.

Phlebotomine mortality effect of systemic insecticides administered to dogs.

Background: Zoonotic visceral leishmaniasis (ZVL) caused by Leishmania (Leishmania) infantum is an important disease in humans and dogs. Different mammal species are reservoirs but dogs are considered to be the main one. Phlebotomine sand flies are the proven vector.

High resolution atomic force microscopy of double-stranded RNA.

Double-stranded (ds) RNA mediates the suppression of specific gene expression, it is the genetic material of a number of viruses, and a key activator of the innate immune response against viral infections. The ever increasing list of roles played by dsRNA in the cell and its potential biotechnological applications over the last decade has raised an interest for the characterization of its mechanical properties and structure, and that includes approaches using Atomic Force Microscopy (AFM) and other single-molecule techniques. Recent reports have resolved the structure of dsDNA with AFM at unprecedented resolution.

Magnetic Force Microscopy in Liquids.

In this work, the use of magnetic force microscopy (MFM) to acquire images of magnetic nanostructures in liquid environments is presented. Optimization of the MFM signal acquisition in liquid media is performed and it is applied to characterize the magnetic signal of magnetite nanoparticles. The ability for detecting magnetic nanostructures along with the well-known capabilities of atomic force microscopy in liquids suggests potential applications in fields such as nanomedicine, nanobiotechnology, or nanocatalysis.

'Flatten plus': a recent implementation in WSxM for biological research.

Unlabelled: Scanning probe microscopy (SPM) is already a relevant tool in biological research at the nanoscale. We present 'Flatten plus', a recent and helpful implementation in the well-known WSxM free software package. 'Flatten plus' allows reducing low-frequency noise in SPM images in a semi-automated way preventing the appearance of typical artifacts associated with such filters.
