Biochar supplementation affects the microbiome of recycled manure solids for cow bedding: a metagenomic analysis.

The widespread use of Recycled Manure Solids (RMS) as cow bedding material is not without risks, since cattle manure may act as a vehicle for pathogenic and antimicrobial resistant bacteria dissemination. Thus, our aim was to evaluate RMS-supplemented with a pine biochar produced in Portugal as a new cow bedding material, since the use of biochar has been shown to have the potential to mitigate the impact of relevant bacterial species when added to animal manure microbiota. Our experimental setup consisted on fresh RMS samples that were collected on a commercial dairy farm and placed in naturally-ventilated containers for a total of 4 groups: 1-non-supplemented RMS; 2-RMS supplemented with 2.

Sleep Quality among Older Adults in Brazil during the Coronavirus Disease 2019 Pandemic: The Role of Physical Activity.

 To assess sleep quality and sleepiness among older adults after social distancing during the coronavirus disease 2019 (COVID-19) pandemic and its association with physical activity.  The present cross-sectional study included a sample of 290 Brazilians aged ≥ 60 years. Subjective sleep quality and sleepiness were assessed using the Mini-Sleep Questionnaire (MSQ) and the Epworth Sleepiness Scale (ESS).

Evidences of radioresistance in from Northeastern Brazil.

Background: Ionizing radiation can inflict cellular damage, the severity of which is determined by the dose, exposure duration, and its capacity to penetrate cells. Some studies have demonstrated that genetic and epigenetic mechanisms have enabled organisms to develop adaptive traits and enhance their ability to repair DNA damage. Northeastern Brazil, a region containing rocky outcrops rich in uranium and thorium, is an ideal scenario to study natural radiation and its effects on natural populations.

A Comparative Retrospective Study on Surgical Versus Conservative Treatment of Simple Fifth Metacarpal Neck Fractures.

Introduction The fifth metacarpal neck fracture is a common injury, and the treatment of such injuries is still a matter of debate. It typically presents in young adults of working age, and it represents a significant burden for both the health services and the patient. The purpose of this study was to compare the results of operative and conservative treatment of this fracture.

Cross-cultural adaptation and validation of the nutrition knowledge questionnaire for ultra-endurance athletes (ULTRA-Q) for Brazil.

Aims: This study aimed to perform a cross-cultural adaptation and validate a questionnaire to assess the nutrition knowledge of Brazilian ultra-endurance athletes.

Methods: This is an observational and cross-sectional study, which adapted and validated the Nutritional Knowledge Questionnaire for Ultra-endurance Athletes (ULTRA-Q). ULTRA-Q was translated into Portuguese, and then the translated version was assessed for semantic, idiomatic, cultural and conceptual equivalence by six specialist nutritionists.
