Background/Aims: Predialysis hyponatremia has been recently reported to be associated with mortality in incident hemodialysis patients. However, whether hyponatremia is associated with unfavorable outcomes in elderly patients remains unknown. We hypothesized that nephrology referral inf luences hyponatremia, and aimed to define how nephrology referral affects the association between hyponatremia and mortality in the elderly. Methods: We retrospectively assessed mortality in 599 incident hemodialysis patients aged ≥ 70 at a tertiary university hospital, between 2000 and 2010...

Locomotion issues in broiler production may decrease performance (carcass yield and traits) and lead to high financial losses. This study evaluates the addition of glucosaminoglycans in broiler diets to minimize the lack of proper bone development and joint weakening. The experiment was conducted using 2,160 broilers randomly distributed in a factorial pattern (3 × 3) using 3 levels of glucosamine sulfate (0, 0.12, and 0.24%) and 3 levels of chondroitin sulfate addition (0, 0.08, and 0.16%). Eight repetitions were used for each treatment, distributed in 72 pens with 30 broilers each...

Adeno-associated virus (AAV; genus Dependoparvovirus, family Parvoviridae) was first discovered in 1965 as a contaminant in adenovirus preparations. The AAVs are generally considered non-pathogenic, and they have the ability to attenuate the replication of other more pathogenic viruses, which makes them attractive as potential therapeutics or preventative measures. This study characterized a novel AAV isolated from Muscovy ducks in China. The novel virus (MHH-05-2015) was isolated after propagating a field isolate of the DAdV-3 virus (a type 3 duck adenovirus) in duck embryo fibroblasts...

The influence of hot conditions on 12-week-old turkey hens and 16-week-old toms while crated at transport density was evaluated. Forty-eight hens and 48 toms (8 birds per flock × 3 flocks × 2 humidity levels) were used in neutral treatments (trt; 20°C), and 16 hens and 16 toms (8 birds per flock × 1 flock × 2 humidity levels) were used in the hot trt (35°C). Birds were placed in crates at a transport stocking density of approximately 83 kg/m2, then inside a pre-conditioned chamber for 8 hours. Live shrink, core body temperature (CBT), heterophil/lymphocyte (H/L) ratio, and breast and thigh pH and color were recorded...

The tyrosinase (TYR) gene is the major melanogenesis-related gene for skin (fur) or plumage color in mammals and birds. Genetic variation in the promoter region of a gene may affect gene expression and phenotypes. This study compared the TYR promoter region between pooled DNA (n = 8) of chickens (Gallus gallus) with black and white skin using direct sequencing. The single nucleotide polymorphism (SNP) c.-2228A>T was found to have the opposite allele distribution in the two groups. The results of genotyping in a larger population (n = 188) revealed that SNP c...

The fertilizing capacity of pure, fresh avian semen may disappear in just half an hour, hindering its successful use in artificial insemination (AI) projects. Longer storage requires the use of infra-physiological temperatures and of semen diluents that help preserve the spermatozoa but that do not interfere with their fertilizing capacity. This study examines the effect on sperm quality of storing red-legged partridge sperm for 3 h at 5°C with 2 different semen extenders: 1) a medium referred to as L&R-84, composed of sodium glutamate, glucose, magnesium acetate, potassium acetate, and polyvinylpyrrolidone, and 2) Lake 7...

Disinfection of hatching eggs is essential to ensure high quality production of broilers. Different protocols are followed in different hatcheries; however, only limited scientific evidence on how the disinfection procedures impact the microbiome is available. The aim of the present study was to characterize the microbiome and aerobic bacterial load of hatching eggs before disinfection and during the subsequent disinfection steps. The study included a group of visibly clean and a group of visibly dirty eggs...

The aim of this work was to study the effects of incorporating sugar beet pulp (SBP) into the diet of geese in two feeding systems (complete pelleted feed or loose-mix feeding system) on crop development and performance. A total of 480 1-d-old male geese were divided into three groups whose diet differed from d 56 to 90: a complete pelleted diet containing 50% corn (control diet: AMEn 11.5 MJ/kg; CP 161 g/kg), and no SBP; a complete pelleted diet containing 50% corn and 10% SBP (SBPcp diet: AMEn: 11.5 MJ/kg; CP: 161 g/kg); and a mix in the same feeder (SBPlm diet) of 500 g/kg of protein-rich pellets containing 20% SBP (SBPprp: AMEn: 9...

The tiered aviary for laying hens includes a floor litter area to promote foraging and dust bathing. Data are needed on hens' use of different litter substrates and effectiveness of substrates in removing excess feather lipids to ensure a suitable litter area. Bovans White hens were housed in commercial-style aviaries with access to one of 3 litter substrates (wood shavings, straw, or plastic turf mats-AstroTurf®, n = 4 aviary pens per substrate, 144 cage-reared hens populated per pen). Litter areas were videoed across 2 d each at 4 ages: immediately following first aviary opening (25 wk), then at 28, 50, and 68 weeks...

The adaptation of chickens to free-range rearing systems mainly involves the locomotory behavior, which is very different in fast-growing (FG) and slow-growing (SG) strains. This study aimed to compare the effect of moderate locomotory activity (induced and prolonged) on the blood oxidative status in a slow-growing chicken strain with that in a fast-growing one. Thirty FG (Ross 308) birds and 30 SG (Hubbard) birds were divided into 2 groups for each strain and subjected to different treatments: no exercise (the control group [C]) and 1 h of walking at 4 km/h (the exercise group [E])...

The adult myogenic population of stem cells, called satellite cells, initially develop in late-term embryos. Satellite cells are the only myogenic cell that repair damaged myofibers and increase post-hatch growth. The objective of the current study was to determine if incubation temperatures and time of hatch impact growth and pectoralis major (p. major) muscle morphology. Eggs were incubated at a constant 37.8°C; however, from d 14 to 18, the eggs were subject to 39.5°C for 0, 3, or 12 h per day. Chicks were divided into early, mid, or late hatch groups based upon the time they emerged from the shell...

Standards for feeder (a.k.a. feed trough) space allowance (SA) are based primarily on studies in conventional cages where laying hens tend to eat simultaneously, limiting feeder space. Large furnished cages (FC) offer more total space and opportunities to perform a greater variety of behaviors, which may affect feeding behavior and feeder space requirements. Our objective was to determine the effects of floor/feeder SA on behavior at the feeder. LSL-Lite hens were housed in FC equipped with a nest, perches, and a scratch mat...

Mycoplasma gallisepticum (MG) is a bacterial pathogen that causes production losses in layer chickens. To combat MG, multiage layer facilities vaccinate pullets by either spray or eye-drop vaccination. The objective in this study was to evaluate the use of in ovo vaccination as a potential alternative for MG vaccination. Layer embryos at 18 d of incubation were either not-injected (control), or were hand-injected with either commercial Marek's disease vaccine diluent alone or with a high, medium, low, or very low dosage of a live attenuated strain F (FMG) vaccine suspended in the commercial diluent...

The mitochondrial proteins TRAP1 and HTRA2 have previously been shown to be phosphorylated in the presence of the Parkinson's disease kinase PINK1 but the downstream signalling is unknown. HTRA2 and PINK1 loss of function causes parkinsonism in humans and animals. Here, we identified TRAP1 as an interactor of HTRA2 using an unbiased mass spectrometry approach. In our human cell models, TRAP1 overexpression is protective, rescuing HTRA2 and PINK1-associated mitochondrial dysfunction and suggesting that TRAP1 acts downstream of HTRA2 and PINK1...

De novo in-frame deletions and duplications in the SPTAN1 gene, encoding the non-erythrocyte αII spectrin, have been associated with severe West syndrome with hypomyelination and pontocerebellar atrophy. We aimed at comprehensively delineating the phenotypic spectrum associated with SPTAN1 mutations. Using different molecular genetic techniques, we identified 20 patients with a pathogenic or likely pathogenic SPTAN1 variant and reviewed their clinical, genetic and imaging data. SPTAN1 de novo alterations included seven unique missense variants and nine in-frame deletions/duplications of which 12 were novel...

See Lenck-Santini (doi:10.1093/awx205) for a scientific commentary on this article. Epileptic seizures represent altered neuronal network dynamics, but the temporal evolution and cellular substrates of the neuronal activity patterns associated with spontaneous seizures are not fully understood. We used simultaneous recordings from multiple neurons in the hippocampus and neocortex of rats with chronic temporal lobe epilepsy to demonstrate that subsets of cells discharge in a highly stereotypical sequential pattern during ictal events, and that these stereotypical patterns were reproducible across consecutive seizures...

See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit...
