Visceral leishmaniasis (VL) is a neglected tropical disease that affects the poorest communities and can cause substantial morbidity and mortality. Visceral leishmaniasis is characterized by the presence of Leishmania parasites in the spleen, liver and bone marrow, hepatosplenomegaly, pancytopenia, prolonged fever, systemic inflammation and low body mass index (BMI). The factors impacting on the severity of VL are poorly characterized. Here we performed a cross-sectional study to assess whether co-infection of VL patients with intestinal parasites influences disease severity, assessed with clinical and haematological data, inflammation, cytokine profiles and BMI...

BACKGROUND: We previously developed an animal model to examine mechanisms that underlie the emergence of visceral hypersensitivity modeling pain characteristics of temporomandibular disorder (TMD) patients with comorbid irritable bowel syndrome (IBS). In ovariectomized (OVx) rats with estradiol (E2) replacement, visceral hypersensitivity developed subsequent to masseter muscle inflammation followed by repeated forced swim (FS) stress. The purpose of this study was to investigate whether activation of extracellular signal-regulated kinase (ERK) in the spinal cord contributes to visceral hypersensitivity in this overlapping pain model...

BACKGROUND: Abnormal central nervous system processing of visceral sensation may be a part of the pathogenesis behind idiopathic fecal incontinence (IFI). Our aim was to characterize brain differences in patients with IFI and healthy controls by means of structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). METHODS: In 21 female patients with IFI and 15 female healthy controls, whole-brain structural differences in gray matter volume (GMV), cortical thickness, and white matter tracts fractional anisotropy (FA) were quantified...

OBJECTIVE: Molecular pathways governing blood vessel patterning are vital to vertebrate development. Because of their ability to counteract proangiogenic factors, antiangiogenic secreted Sema3 (class 3 semaphorins) control embryonic vascular morphogenesis. However, if and how Sema3 may play a role in the control of extraembryonic vascular development is presently unknown. APPROACH AND RESULTS: By characterizing genetically modified mice, here, we show that surprisingly Sema3F acts instead as a selective extraembryonic but not intraembryonic proangiogenic cue...

Autonomic dysreflexia is a dangerous elevation in blood pressure in people with spinal cord injury (SCI), produced by a spinally-mediated reflex activation of sympathetic vasoconstrictor neurones supplying skeletal muscle and the gut. Current dogma states that, apart from visceral inputs - such as those originating from a distended bladder or impacted colon - autonomic dysreflexia is triggered by noxious inputs below the lesion. However, while selective stimulation of small-diameter afferents in muscle or skin evokes a sustained increase in muscle sympathetic nerve activity and blood pressure, and a transient increase in skin sympathetic nerve activity and decrease in skin blood flow in able-bodied subjects, such noxious inputs have no effects on blood pressure and skin blood flow in SCI individuals...

BACKGROUND: The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain...

Low fat mass is associated with an increased risk of fracture because of low bone mineral density (BMD) and altered bone micro-architecture. Conversely, overweight and obese patients also have an increased risk of fracture, particularly of the humerus and ankle, despite greater BMD. Visceral abdominal fat, which is the most metabolically active, may be associated with poorer quality of bone tissue properties, as suggested in diabetes. Other factors may contribute to higher fracture risk in overweight patients, notably higher frequency of falls and lower bioavailability of vitamin D stoked in fat...

Euthanasia of infected dogs is one of the measures adopted in Brazil to control visceral leishmaniasis (VL) in endemic areas. To detect infected dogs, animals are screened with the rapid test DPP® Visceral Canine Leishmaniasis for detection of antibodies against K26/K39 fusion antigens of amastigotes (DPP). DPP-positives are confirmed with an immunoenzymatic assay probing soluble antigens of promastigotes (ELISA), while DPP-negatives are considered free of infection. Here, 975 dogs from an endemic region were surveyed by using DPP, ELISA and real-time PCR (qPCR) for the diagnosis of VL...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

OBJECTIVE: Hepatic steatosis (HS) is common in HIV-infected individuals. Magnetic resonance spectroscopy (MRS) is the preferred non-invasive method for HS measurement but is expensive. Controlled attenuation parameter (CAP) also assesses HS and is conveniently performed concomitantly with transient elastography. We aimed to assess the accuracy of CAP in the setting of HIV infection. DESIGN: Cross-sectional study. METHODS: CAP and MRS were performed in 82 subjects (39 HIV-monoinfected;7 HCV-monoinfected;21 HIV/HCV-coinfected; 15 with neither infection)...

Visceral adiposity confers significant risk for developing metabolic disease in obesity whereas preferential expansion of subcutaneous white adipose tissue (WAT) appears protective. Unlike subcutaneous WAT, visceral WAT is resistant to adopting a protective thermogenic phenotype characterized by the accumulation of Ucp1(+) beige/BRITE adipocytes (termed "browning"). In this study, we investigated the physiological consequences of browning murine visceral WAT by selective genetic ablation of Zfp423, a transcriptional suppressor of the adipocyte thermogenic program...

Different visceral fat compartments have several systemic effects and may play a role in the development of both insulin resistance and cardiovascular diseases. In the last couple of years special attention has been paid to the epicardial adipose tissue (EAT), which can be quantified by non-invasive cardiac imaging techniques. The epicardial fat is a unique fat compartment between the myocardium and the visceral pericardium sharing a common embryologic origin with the visceral fat depot. Epicardial adipose tissue has several specific roles, and its local effects on cardiac function are incorporated in the complex pathomechanism of coronary artery disease...
