The degree of fetal growth restriction has been unclear in equine reproduction. In this study, 2,195 fetuses from 2,137 abortions during 11 seasons were examined to determine the causes of abortion, and fetal size dimensions (crown rump length and body weight) were measured. In total, 900 cases (42.1%) of abortion were identified as caused by viral infection (215, 10.1%), bacterial infection (156, 7.3%), fungal infection (25, 1.2%), circulation failure (406, 19.0%), multiple causes (66, 3.1%), deformity (13, 0...

Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed salmon frequently experience environmental hypoxia, the current study examined mutual effects of PRV infection and hypoxia on pathogenesis and fish performance. Furthermore, effects of HSMI on hypoxia tolerance, cardiorespiratory performance and blood oxygen transport were studied. A cohabitation trial including PRV-infected post-smolts exposed to periodic hypoxic stress (4 h of 40% O2; PRV-H) at 4, 7 and 10 weeks post-infection (WPI) and infected fish reared under normoxic conditions (PRV) was conducted...

PURPOSE: The significance of sarcopenia after colorectal cancer (CRC) resection has only been discussed with relatively small samples or short follow-up periods. This study aimed to clarify the clinical significance of sarcopenia in a large-sample study. METHODS: We retrospectively analyzed the relationship between sarcopenia and clinical factors, surgical outcomes, and the survival in 494 patients who underwent CRC surgery between 2004 and 2013. Sarcopenia was defined based on the sex-specific skeletal muscle mass index measured by preoperative computed tomography...

Enterovirus A71 (EV-A71) causes hand-foot-and-mouth disease (HFMD), which may be complicated by fatal encephalomyelitis. Although fecal-oral or oral-oral routes are important in person-to-person transmission, how viral shedding and exposure may predispose individuals to infection remains unknown. We investigated person-to-person transmission by using a model of HFMD and encephalomyelitis based on EV-A71 oral infection of 2-week-old hamsters. Animals (index animals) infected with 10(4) 50% cell culture infective doses of virus uniformly developed severe disease four days post-infection (dpi), whereas littermate contacts developed severe disease after six to seven days of exposure to index animals...

Exertional dyspnoea is a leading symptom in patients with pulmonary arterial hypertension (PAH). Patients suffering from PAH report poor quality of life, have skeletal muscle dysfunction and in the absence of advanced medical therapy deteriorate progressively due to right heart failure which can lead to death. For decades, patients with PAH were advised to avoid exercise in fear of exacerbated right heart failure. Recently, it has been shown that a highly supervised rehabilitation programme in expert centres leads to significant improvements in symptoms, quality of life, exercise capacity and may even enhance haemodynamics in selected stable patients treated with advanced regimens of PAH-targeted drugs...

The zoonotic infection hydatidosis is caused by the tapeworm cestode, Echinococcus granulosus. Though considered endemic in India where association of humans with sheep and dogs form part of the livelihood, primary skeletal muscle involvement of the disease is an extremely rare event. We report a case of primary paraspinal hydatidosis with extradural extension causing acute paraplegia. Excision of the cyst and decompression of the cord was done along with albendazole therapy. Paraspinal hydatid disease is a rare entity, and in regions where hydatid disease is endemic, it can be involved in the differential diagnosis of acute compressive myelopathy...

Millions of people worldwide take tenofovir disoproxil fumarate (TDF) for the treatment of human immunodeficiency virus (HIV) and/or hepatitis B infection. Although generally safe and well tolerated, clinicians need to be aware that TDF can cause proximal renal tubular dysfunction and loss of bone mineral density, especially in patients with concomitant renal disease or other risk factors. We present the case of a patient with chronic HIV infection and urethral stricture who developed TDF-related proximal renal tubular dysfunction with hypophosphatemia and osteomalacia, presenting with bone pains, skeletal deformity, and disability...

A new disease in farmed rainbow trout (Onchorhyncus mykiss) was described in Norway in 2013. The disease mainly affected the heart and resembled heart and skeletal muscle inflammation (HSMI) in Atlantic salmon (Salmo salar L.). HSMI is associated with Piscine orthoreovirus (PRV), and a search for a similar virus in the diseased rainbow trout led to detection of a sequence with 85% similarity to PRV. This finding called for a targeted effort to assess the risk the new PRV-variant pose on farmed rainbow trout and Atlantic salmon by studying infection and disease pathogenesis, aiming to provide more diagnostic knowledge...

STUDY DESIGN: Retrospective observational study. PURPOSE: The aim of this study was to assess the distribution of age and site of infection in patients with musculoskeletal tuberculosis (TB) and determine the number of TB/human immunodeficiency virus (HIV) coinfections as well as the incidence of multidrugresistant (MDR) TB. OVERVIEW OF LITERATURE: Of all TB cases, 1%-3% show skeletal system involvement and 30% are HIV coinfected. Although the reported distribution of skeletal TB is majorly in the spine, followed by the hip, knee, and foot/ankle, the epidemiology of extrapulmonary TB and especially musculoskeletal TB remains largely unknown, particularly in areas with a high prevalence of the disease...

Early detection of sarcopenia might help preventing muscle loss and disability in HIV-infected patients. This study proposed a model for estimating appendicular skeletal muscle mass (ASM) in order to calculate indices to identify 'sarcopenia' (SA) and 'risk for disability due to sarcopenia' (RSA) in patients with HIV. An equation to estimate ASM was developed in 56 patients (47.2±6.9 yrs), with a cross-validation sample of 24 patients (48.1 ± 6.6 yrs). The model validity was determined by calculating, in both samples: a) Concordance between actual vs...

Here, we report a new species of Sarcocystis with red-tailed hawk (RTH) as the natural definitive host and IFN-γ gene knockout (KO) mice as an experimental intermediate host in which sarcocysts form in muscle. Two RTHs submitted to the Carolina Raptor Center, Huntersville, North Carolina, were euthanized because they could not be rehabilitated and released. Fully sporulated 12.5 x 9.9 m sized sporocysts were found in intestinal scrapings of both hawks. Sporocysts were orally fed to laboratory-reared outbred Swiss Webster mice (SW) (Mus musculus) and also to KO mice...

Skeletal muscle stem cells play a critical role in regeneration of myofibers. We have previously demonstrated that chronic binge alcohol (CBA) markedly attenuates myoblast differentiation potential and myogenic gene expression. Muscle specific microRNAs are implicated in regulating myogenic genes. The aim of this study was to determine whether myoblasts isolated from asymptomatic CBA administered SIV-infected macaques treated with antiretroviral therapy (ART) showed similar impairments and if so, to elucidate potential underlying mechanisms...

Zika virus (ZIKV) was considered an innocent pathogen while restricted to the African and Asian population; however, after reaching the Americas in March 2015, it became a global threat. Despite usually causing mild or no symptoms in infected adults, ZIKV displays a different behavior towards fetuses. When infected during gestation, fetuses have their immature neural cells killed by the virus and consequently have devastating findings at birth. In the past year, the drastic effects of ZIKV infection in newborns include neurological, ophthalmological, audiological, and skeletal abnormalities...
