PM/PM ratios in southernmost Brazilian cities and its relation with economic contexts and meteorological factors.

The PM/PM ratio is a metric used to distinguish the primary sources of particulate matter (PM) within a given environment. Higher ratios often indicate significant contributions from anthropogenic sources, while smaller ratios suggest a substantial influence from natural origins. However, various contextual factors can influence this ratio.

Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.

The Feeling of Fatigue Scale for Brazilian Fighter Pilots.

Introduction: Fighter pilots are a population particularly vulnerable to developing mental fatigue, which puts the safety of military operations at risk. Although there is no gold standard tool for its assessment, Yoshitake's Feeling of Fatigue Scale (FFS) appears promising for application to fighter pilots as it has already been validated for Brazilian commercial airline pilots. The objective of this study was to evaluate the psychometric properties of the FFS in Brazilian fighter pilots.

Unlabelled: is a ubiquitous environmental pathogen. Despite its remarkable adaptability, little is known about the mechanisms of stress resistance in this bacterium. Here, in a screen for iron-susceptible transposon mutants, we identified a cytochrome that protects against multiple stresses.

Regional challenges to optimize the management of patients with severe asthma type 2 inflammation: a Delphi consensus in seven countries.

Severe asthma burdens patients and presents clinical management challenges for healthcare professionals. Biologics are crucial interventions for severe type two (T2) patients with high eosinophil counts. We conducted a Delphi consensus in seven developing or typically underrepresented countries to understand expert agreement on managing severe asthma with type two (T2) inflammation.

Angiostrongylus cantonensis, commonly known as the rat lungworm, causes Eosinophilic meningitis in humans. Our study aimed to investigate the prevalence and distribution of this parasite in rats in Haiti. Rats were trapped at 8 sites, 7 in Artibonite (rural region) and one in an urban area of Port-au-Prince.

A Systematic Review of Parental Occupational Pesticide Exposure and Geographical Proximity to Agricultural Fields in Association with Neural Tube Defects.

Neural tube defects (NTDs) are the second most common congenital anomaly and have been widely associated with exposure to pesticides. This systematic review which analyzes the association between parental exposure to pesticides and NTDs was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The search strategy was designed considering the population, exposure, controls, outcomes, and study design (PECOS).

Physical and Sensory Long-Term Disabilities from Snakebite Envenomings in Manaus, Western Brazilian Amazon.

Snakebites caused by snakes are the most prevalent in the Amazon region, causing local and systemic complications. Local complications are mostly represented by necrosis, secondary bacterial infection and compartment syndrome. There are reports of long-term disabilities, but their burden is poorly investigated.

Trimethylamine N-Oxide (TMAO) Plasma Levels in Patients with Different Stages of Chronic Kidney Disease.

Background: In patients with chronic kidney disease (CKD), trimethylamine n-oxide (TMAO) accumulation exacerbates inflammation and contributes to oxidative stress. These complications are putatively linked to the development of cardiovascular diseases. Despite the known associations, the variation in TMAO plasma levels across different CKD stages and dialysis modalities remains underexplored.

Efficacy of Fat Supplements with Different Unsaturated/Saturated FA Ratios Undergoing First Postpartum Ovulation in Lactating Anovulatory Goats.

We investigated whether microalgae or linseed supply during the early postpartum period affects ovarian restimulation and supports the first postpartum ovulation in lactating anovulatory goats. Thirty-eight An-glo-Nubian-crossbred adult goats were allocated into three groups, one with a control diet ( = 12), fed a total mixed ration (TMR) comprising chopped elephant grass and concentrate; an algal diet ( = 13), fed TMR + green microalgae (1% dry matter); and a linseed diet ( = 13), TMR + linseed (12% dry matter). Supplements were furnished from the second to fifth week (time of weaning).

Diagnostic Limitations of Applying a Human Portable Blood Glucose Meter in the Detection of Hypoglycemia in Pregnant Ewes.

Pregnant ewes are susceptible to hypoglycemia and ketosis; therefore, monitoring glycemic status is extremely important. Portable blood glucose meters (PBGMs) can assist in quickly and conveniently identifying glycemic disturbances in this species, provided that they meet the criteria of analytical accuracy. This study evaluated the performance of a human PBGM (Accu-Chek Performa, Roche Diagnostics, Basel, Switzerland) in the glycemic evaluation of 34 pregnant ewes at days 90 and 120 of pregnancy in comparison with the results of glycemia determination by a reference method (RM).

This study evaluated the effects of two types of plastic flooring-one with and one without nanotechnological antimicrobial additives-used as complete or partial replacements for wood shavings on broiler chicken performance, yield, meat quality, and litter microbiology over 42 days. A total of 1500 Ross 408 male broiler chicks were randomly assigned to five treatment groups: wood shavings (WS), plastic flooring (PF), a 50/50 mix of plastic flooring and wood shavings (PF + WS), plastic flooring with antimicrobial additives (PFA), and a 50/50 mix of antimicrobial plastic flooring and wood shavings (PFA + WS). This study evaluated organ biometrics (liver, heart, spleen, and gizzard), the severity of lesions, microbiological profiles, performance indices, and meat quality.

Reproductive Efficiency of Nelore Cows in Fixed-Time Artificial Insemination Programs with Early Resynchronization.

We aimed to evaluate the reproductive efficiency of Nelore cows in fixed-time artificial insemination (FTAI) programs with early resynchronization. A total of 468 Nelore cows were divided into two experimental groups: R30-conventional resynchronization at 30 days ( = 234); R22-early resynchronization at 22 days ( = 234). Both groups followed a synchronization protocol using intravaginal progesterone devices combined with the administration of steroids and gonadotropins.
