Effect of dietary supplementation with rumen-protected amino acids, lysine and methionine, on the performance of Comisana ewes and on the growth of their lambs.

The purpose of the study was to evaluate the effect of supplementing the diets of Comisana ewes with rumen protected methionine and lysine (RP-ML) for a duration of 60 days on quantitative-qualitative production of milk, antioxidant parameters of milk and blood, biochemical parameters of blood, and lambs' growth performance. Two groups of 15 ewes with equal average body weight were considered for the trial. The control group was administered a standard diet (Control, C) and the experimental group the standard diet supplemented with 1.

Does Antiretroviral Therapy Prevent Human T-Lymphotropic Virus 1 Transmission From a Seropositive Donor to a Kidney Transplant Recipient? A Case Report and Literature Review.

Human T-lymphotropic virus 1 produces a latent infection and disease with poor prognosis. Although its transmission during solid-organ transplant and development of the disease has been described, it is not clear whether antiretroviral treatment could prevent it. We report the first kidney transplant of a donor with human T-lymphotropic virus positivity to a negative recipient who was under antiretroviral treatment without evidence of transmission.

Seroprevalence status of vaccine-preventable diseases in migrants living in shelter centers in Barcelona, Spain.

Introduction: Almost 281 million people were living in a foreign country in 2022, and more than 100 million were displaced because of war conflicts and human right violations. Vaccination coverage of infectious diseases in migrants from some disadvantaged settings could be lower than reception countries populations, consequently seroprevalence studies and better access to vaccination could contribute to reducing these differences.

Methods: A descriptive retrospective cross-sectional study was conducted including migrants, living ≤5 years in the reception country and ≥16 years old, who requested a medical exam between January 1st, 2020 and January 31st, 2021.

The incidence of HIV-2 infection in Spain is declining - a registry data analysis.

Objectives: HIV-2 infection is a neglected disease caused by a human retrovirus that causes AIDS more slowly than HIV-1. Infection with HIV-2 is endemic in West Africa. Given its differential features, guidelines recommend ruling out HIV-2 infection in all newly diagnosed HIV-seropositive individuals.

Vaccine Safety and Immunogenicity in Patients With Multiple Sclerosis Treated With Natalizumab.

Importance: Vaccination in patients with highly active multiple sclerosis (MS) requiring prompt treatment initiation may result in impaired vaccine responses and/or treatment delay.

Objective: To assess the immunogenicity and safety of inactivated vaccines administered during natalizumab treatment.

Design, Setting, And Participants: This self-controlled, prospective cohort study followed adult patients with MS from 1 study center in Spain from September 2016 to February 2022.
