In 2018, Portuguese researchers proposed the "Tool for Quality Assessment of Genetic Counseling," a 5-point Likert scale comprising 50 items across five dimensions, designed to assess genetic counseling from the professional's perspective. This descriptive, cross-sectional study aimed to adapt this tool to Brazilian Portuguese, validate it among Brazilian clinical geneticists, and conduct a preliminary assessment of the quality of genetic counseling in Brazil. The adaptation process involved expert-driven content validation and calculation of the Content Validity Index (CVI) to ensure equivalence between the original and adapted versions.

We identified seven distinct coronaviruses (CoVs) in bats from Brazil, classified into 229E-related (Alpha-CoV), Nobecovirus, Sarbecovirus, and Merbecovirus (Beta-CoV), including one closely related to MERS-like CoV with 82.8% genome coverage. To accomplish this, we screened 423 oral and rectal swabs from 16 different bat species using molecular assays, RNA sequencing, and evolutionary analysis.

Despite significant progress in understanding the factors influencing cognitive function in Parkinson's disease (PD), there is a notable gap in data representation for the Latinx population. This study aims to evaluate the contributors to and disparities in cognitive performance among Latinx patients with PD. A retrospective analysis was conducted based on cross-sectional data encompassing demographic, environmental, motor, and non-motor disease characteristics from the Latin American Research Consortium on the Genetics of PD (LARGE-PD) and the Parkinson's Progression Markers Initiative (PPMI) cohorts.

The present systematic review aims to put together human population studies that include some relationship between genetic polymorphisms and genotoxicity as well as to evaluate the quality of the published studies induced by cigarette smoke exposure in vivo. The present systematic review was built according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Different genotoxicity assays were used by different authors, although the major goal was the genotoxicity assessment by means of micronucleus, comet, sister chromatid exchange, and chromosomal aberration assays.

Nicotine is one of the most toxic substances found in cigarettes, but also found in chewing tobacco gum, patches and vaping products (electronic cigarettes). In addition to being a highly addictive chemical, it is capable of reducing fertility in men and women. In the ovaries, it can induce morphological changes and impair the formation of follicles, being a possible cause of changes in the reproductive cycle and anticipation of menopause in women whose mothers smoked during pregnancy.

Glutamine availability may be reduced in chronic diseases, such as type 2 diabetes mellitus (T2DM)-induced by obesity. Herein, the antioxidant, anti-inflammatory and lipid metabolism effects of chronic oral glutamine supplementation in its free and dipeptide form were assessed in ob/ob mice. Adult male C57BL/6J ob/ob mice were supplemented with L-alanyl-L-glutamine (DIP) or free L-glutamine (GLN) in the drinking water for 40 days, whilst C57BL/6J Wild-type lean (WT) and control ob/ob mice (CTRL) received fresh water only.

Forest restoration has been a common practice to safeguard water quality and stream health but it is unclear to which extent and pace forest restoration recovers stream ecosystem structure and functions. Also, stream health might be affected by the forest restoration type and the quality of the interventions. Here, we sought to evaluate the recovery of stream habitat and water quality through forest restoration in catchments dominated by pasturelands, and explored the relationship between landscape structure and stream ecosystem recovery.

Background: Radiofrequency ablation guided by ultrasound (RFA-USG) is an alternative treatment for primary hyperparathyroidism (PHPT) patients. Despite showing accurate precision and minimal invasion, its efficacy remains questionable.

Methods: We searched PubMed, Embase, Scopus, Cochrane Library, Portal Regional da Biblioteca Virtual em Saúde (BVS), Web of Science databases for randomized controlled trials (RCTs) and observational studies evaluating RFA-USG in PHPT patients.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.

Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).

An 88-year-old woman presented with a longstanding history of dizziness, tremors, and progressive mental and physical decline, significantly impairing her mobility and autonomy. Recently discharged from an ICU, the patient required extensive support for daily activities. Diagnostic evaluations, including EEG and analysis, revealed irregular frequency peaks and altered cortical activity, particularly in the frontal and prefrontal regions.

Solar-based technologies for removing potentially toxic metals from water sources: a review.

Environ Sci Pollut Res Int

January 2025

Departamento de Ciência E Tecnologia de Alimentos, Universidade Federal de Santa Catarina, Rod. Admar Gonzaga, 1346, Itacorubi, Florianópolis, Santa Catarina, 88034-001, Brazil.

Technological advances have led to a proportional increase in the deposition of contaminants across various environmental compartments, including water sources. Heavy metals, also known as potentially toxic metals, are of particular concern due to their significant harmful impacts on environmental and human health. Among the available methods for mitigating the threat of these metals in water, solar radiation-based technologies stand out for their cleanliness, cost-effectiveness, and efficiency in removing or reducing the toxicity of heavy metals.

Fusarium keratitis (FK) is an important clinical condition that can lead to blindness and eye loss, and is most commonly caused by the Fusarium solani species complex (FSSC). This study evaluated the susceptibility of planktonic cells and biofilms of FSSC (n = 7) and non-FSSC (n = 7) isolates obtained from patients with keratitis from a semi-arid tropical region to amphotericin B (AMB), natamycin (NAT), voriconazole (VRZ), efinaconazole (EFZ), and luliconazole (LCZ). Analysis of clinical data showed that trauma was the most common risk factor for FK patients.

Genetic competition can obscure the true merit of selection candidates, potentially leading to altered genotype rankings and a divergence between expected and actual genetic gains. Despite a wealth of literature on genetic competition in plant and animal breeding, the separation of genetic values into direct genetic effects (DGE, related to a genotype's merit) and indirect genetic effects (IGE, related to the effects of a genotype's alleles on its neighbor's phenotype) in linear mixed models is often overlooked, likely due to the complexity involved. To address this, we introduce gencomp, a new R package designed to simplify the use of (spatial-) genetic competition models in crop and tree breeding routines.

Background: Brazilian spotted fever is a tick-borne disease caused by the bacterium Rickettsia rickettsii, whose main vector in Brazil is the tick Amblyomma sculptum. Amplifying hosts are essential for the perpetuation of this bacterium in the tick population as they can be sources of infection during bacteremic periods. Recent studies demonstrated the ability of suids (Sus scrofa) to sustain populations of A.
