Development and validation of a model for early prediction of residual feed intake in beef cattle using plasma biomarkers.

Identification of plasma biomarkers for feed efficiency in growing beef cattle offers a promising opportunity for developing prediction models to improve precision feeding strategies. However, these models must accurately predict feed efficiency at early stages of fattening. Our study aimed to evaluate the reliability of candidate biomarkers previously identified in late-fattening cattle when analysed during early fattening stages and to develop diet-specific prediction equations for residual feed intake (RFI).

Gut Microbiota Diversity of Local Egyptian Cattle Managed in Different Ecosystems.

The animal gastrointestinal tract contains a complex microbiome whose composition ultimately reflects the co-evolution of microorganisms with their animal host and their host's environment. This study aimed to gain insights into the adaptation of the microbiota of local Egyptian cattle to three different ecosystems (Upper Egypt, Middle Egypt, and Lower Egypt) distributed across 11 governorates (with an average of 12 animals per governorate) using amplicon sequencing. We analyzed the microbiota from 136 fecal samples of local Egyptian cattle through a 16S rRNA gene sequencing approach to better understand the fecal microbial diversity of this breed which developed under different ecosystems.

Metagenome reveals caprine abomasal microbiota diversity at early and late stages of Haemonchus contortus infection.

Haemonchus contortus is one of the most detrimental gastrointestinal nematode parasites for small ruminants, especially in tropics and subtropics. Gastrointestinal nematode and microbiota share the same microhabitat; thus they interact with each other and their host. Metagenomics tools provide a promising way to examine the alterations in the gastric microbial composition induces by gastrointestinal parasites.

Early Transcriptome Differences Between Pre-Infected and Naïve Kid Goats Infected With .

In small ruminant production, gastrointestinal nematode (GIN) infection is one of the major causes of economic losses. The aim of this study was to compare the abomasal mucosa transcriptome of naïve and pre-infected goats at early time points after infection, in order to identify different pathways and upstream regulators involved in the host immune response. Naïve and pre-infected Creole kids were orally infected with 10,000 infective larvae (L3), and abomasal mucosa was sampled at 0, 4, and 6 days post-infection (dpi).

Genomic variants from RNA-seq for goats resistant or susceptible to gastrointestinal nematode infection.

Gastrointestinal nematodes (GIN) are an important constraint in small ruminant production. Genetic selection for resistant animals is a potential sustainable control strategy. Advances in molecular genetics have led to the identification of several molecular genetic markers associated with genes affecting economic relevant traits.

Immunoglobulins as Biomarkers for Gastrointestinal Nematodes Resistance in Small Ruminants: A systematic review.

The rise of anthelmintic resistance worldwide has led to the development of alternative control strategies for gastrointestinal nematodes (GIN) infections, which are one of the main constraints on the health of grazing small ruminants. Presently, breeding schemes rely mainly on fecal egg count (FEC) measurements on infected animals which are time-consuming and requires expertise in parasitology. Identifying and understanding the role of immunoglobulins in the mechanisms of resistance could provide a more efficient and sustainable method of identifying nematode-resistant animals for selection.

A six-weekly dosing schedule for pembrolizumab in patients with cancer based on evaluation using modelling and simulation.

Background: Pembrolizumab is approved for multiple cancer types at 200 mg and 2 mg/kg dose every 3 weeks (Q3W). We used a model-based approach to compare the exposure of pembrolizumab 400 mg dose every 6 weeks (Q6W) with the Q3W regimens.

Methods: The Q6W dose was selected by matching exposure with the 200 mg and 2 mg/kg Q3W doses.

Dynamic transcriptomic changes of goat abomasal mucosa in response to Haemonchus contortus infection.

Gastrointestinal nematode (GIN) infections are one of the major constraints for grazing sheep and goat production worldwide. Genetic selection for resistant animals is a promising control strategy. Whole-transcriptome analysis via RNA-sequencing (RNA-seq) provides knowledge of the mechanisms responsible for complex traits such as resistance to GIN infections.

Transcriptome variation in response to gastrointestinal nematode infection in goats.

Gastrointestinal nematodes (GIN) are a major constraint for small ruminant production. Due to the rise of anthelmintic resistance throughout the world, alternative control strategies are needed. The development of GIN resistance breeding programs is a promising strategy.

Anti-angiogenic-specific adverse events in patients with non-small cell lung cancer treated with nintedanib and docetaxel.

Objectives: LUME-Lung 1 was a randomized, placebo-controlled, Phase III trial investigating nintedanib+docetaxel versus placebo+docetaxel in patients with advanced NSCLC progressing after first-line chemotherapy. Progression-free survival was significantly improved with nintedanib+docetaxel in the overall population and overall survival was significantly improved in the pre-specified analysis of patients with adenocarcinoma. We evaluated the frequency of characteristic adverse events (AEs) commonly seen with existing anti-angiogenic agents.

A success story: HIV prevention for injection drug users in Rhode Island.

Background: New HIV diagnoses related to injection drug use (IDU) have declined in the United States. Access to clean syringes and decreasing HIV transmission among injection drug users have been HIV prevention priorities of the Rhode Island (RI) HIV community. To examine trends in IDU-related new HIV diagnoses in RI, we performed a retrospective analysis of new HIV diagnoses according to HIV risk factor from 1990-2003.

Prevalence and predictors of night sweats, day sweats, and hot flashes in older primary care patients: an OKPRN study.

Purpose: We wanted to estimate the prevalence of night sweats, day sweats, and hot flashes in older primary care patients and identify associated factors.

Methods: We undertook a cross-sectional study of patients older than 64 years recruited from the practices of 23 family physicians. Variables included sociodemographic information, health habits, chronic medical problems, symptoms, quality of life, and the degree to which patients were bothered by night sweats, daytime sweating, and hot flashes.
