When to pair: Effects of different pairing ages on dairy calf health, behavior and performance.

Pair housing presents an alternative to individual or larger group housing systems, though the effects of different pairing ages on calf welfare are not well understood. In this study, we examined the impact of pairing age on the performance, health, and behavior of dairy calves. A total of 140 Holstein female calves (n = 70 pairs) were used, paired at 3 ages: Early (6-7 d; 48 calves), Intermediate (29-30 d; 48 calves), and Late pairing (49-50 d; 44 calves).

Kidney Disease and Hematopoietic Stem Cell Transplantation.

Hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for patients with hematologic malignancies and certain solid tumors and nonmalignant hematologic conditions. Both acute kidney injury (AKI) and chronic kidney disease (CKD) occur commonly after HSCT and are associated with significant morbidity and mortality. AKI and CKD in this setting may result from direct effects of the transplant or be caused by pretransplant bone marrow conditioning regimens and/or nephrotoxic agents administered in the post-transplant period.

Biomarkers.

Background: The Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is one of the biggest health concerns of the century. Long COVID is one of the major sequelae from the infection and include persistent neurological manifestations. Brain images study suggest that Long COVID patients present distinct brain metabolic alterations.

Biomarkers.

Background: The COVID-19 pandemic is a public health crisis, and its lasting consequences are not yet fully understood. Epidemiological data suggest that low- and middle-income countries, such as Brazil, will bear a considerable burden of COVID-19-related comorbidities. Individuals who have survived COVID-19 often report persistent symptoms, including neurological manifestations such as brain fog.

Biomarkers.

Background: Long COVID is an under-characterized disorder that affects a wide range of individuals after COVID-19 resolution. Long COVID individuals report persistent neurological manifestations, such as anxiety. Understanding its effects in the brain might help uncover the actual burden imposed by the pandemic sequelae and either define or discard long COVID as a risk factor for neurodegenerative diseases.
