Viral Metagenomics in Patients Who Underwent Allogeneic Hematopoietic Stem Cell Transplantation (HSCT): A Brazilian Experience.

Viral infections are one of the most important causes of morbidity and mortality among patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Immunosuppression may lead to the reactivation of latent viruses or the acquisition of new infections, resulting in severe clinical outcomes. The early detection of viral reactivations is crucial for effective patient management and post-transplant care.

Spatiotemporal Dynamics of SARS-CoV-2 Variants During the First Year of the Pandemic Highlight the Earlier Emergence of the Zeta Variant of Interest in Brazil.

During the COVID-19 pandemic, SARS-CoV-2 caused an alarming number of cases and deaths worldwide. Brazil was severely affected from late 2020 onward, especially after the emergence of variants of concern (VOCs) and variants of interest (VOIs). Although much is known about the dynamics and evolution of SARS-CoV-2 VOIs and VOCs in the country, information is still lacking on how the cocirculation of several SARS-CoV-2 lineages, along with the lack of vaccination and low adherence to social isolation measures, shaped the first year of the COVID-19 pandemic in Brazil.

Tailoring Genomic Selection for : A Comprehensive Review of SNP Arrays and Reference Genomes.

Background: Advances in SNP arrays and reference genome assemblies have significantly transformed cattle genomics, particularly for (Zebu cattle). Many commercial SNP arrays were originally designed for , leading to ascertainment bias and the exclusion of crucial SNPs specific to Zebu populations. This review assesses progress in SNP array and reference genome development, with a focus on efforts tailored to Zebu populations and their impact on genomic selection and breeding efficiency.

Exploring Feed Efficiency in Beef Cattle: From Data Collection to Genetic and Nutritional Modeling.

Increasing feed efficiency in beef cattle is critical for meeting the growing global demand for beef while managing rising feed costs and environmental impacts. Challenges in recording feed intake and combining genomic and nutritional models hinder improvements in feed efficiency for sustainable beef production. This review examines the progression from traditional data collection methods to modern genetic and nutritional approaches that enhance feed efficiency.

Does living in a food desert impact weight loss after bariatric surgery?

Background: Lower access to fresh foods and lower income level are associated with greater obesity rates.

Objectives: We aim to study if weight loss 1 year after bariatric surgery is associated with living in areas defined as food deserts, that is, low access to foods and lower income.

Setting: Virginia Commonwealth University Hospital System, Richmond, VA; Academic Center.
