Background: People living with HIV (PLWH) have lower life expectancy than uninfected individuals, partly explained by excess risk of cardiovascular diseases (CVD) and CVD risk factors. We investigated the association between HIV infection and abdominal obesity, elevated LDL cholesterol (LDL-C), hypertriglyceridemia and hypertension, in a large cohort of predominantly well-treated PLWH and matched controls. Methods: 1,099 PLWH from the Copenhagen Co-morbidity in HIV infection (COCOMO) study and 12,161 age and sex-matched uninfected controls from the Copenhagen General Population Study were included and underwent blood pressure, waist-, hip-, weight-, and height-measurements...

Prior work using a contractility bioassay determined that the serotonin (5-HT) receptor subtype 5-HT2A is present in bovine lateral saphenous veins and plays a role in ergot alkaloid-induced vascular contraction in steers grazing endophyte-infected (Epichloë coenophiala) tall fescue (Lolium arundinaceum). Ergot alkaloids have also been shown to be vasoactive in bovine gut vasculature. To determine what 5-HT receptors are involved in vasoconstriction of gut vasculature, contractility of ruminal and mesenteric arteries and veins collected from cattle were evaluated in the presence of agonists selective for 5-HT1B (CP 93129) 5-HT1D (L-694, 247), 5-HT2A (TCB-2), 5-HT2B (BW 723C86), 5-HT4 (BIMU-8) and 5-HT7 (LP 44) receptors...

OBJECTIVES: The aim of the present study was to determine potential host-, pathogen-, infection- and treatment-related risk factors that might predict a fulminant, fatal course of bacteremia caused extensively drug-resistant A. baumannii (XDR Aba). METHODS: Eighty-seven patients with monomicrobial growth of XDR Aba in blood cultures within a 6-year period were studied. Patients were divided into three groups, according to ICU outcome. Group A (n=40) consisted of patients who survived, Group B (n=10) included patients with fulminant sepsis that died early (<48h), whereas Group C (n=37) included patients that died later (> 48h) after the onset of bacteremia...

This study investigates the production of rabies virus (RABV) neutralizing antibody after virus infection through a mouse model. The BALB/c mice from different age groups (three, five, seven week old) were intramuscularly inoculated with live rabies virus (TX coyote 323R). Without pre-exposure or post-exposure prophylaxis (PEP), we found there is a decreased fatality with increased age of animals, the mortalities are 60%, 50%, and 30%, respectively. Interestingly, through assay of rapid fluorescent focus inhibition test (RFFIT), direct fluorescent antibody (DFA) and quantitative Polymerase Chain Reaction (qPCR), the results showed that all the animals that succumbed to rabies challenge, except one, developed circulating neutralizing antibodies, and all the healthy animals, except two, did not generate virus neutralizing antibodies (VNA)...

Despite playing critical roles in the immune response and having significant potential in immunotherapy, γδ T cells have garnered little of the limelight. One major reason for this paradox is that their antigen recognition mechanisms are largely unknown, limiting our understanding of their biology and our potential to modulate their activity. One of the best-studied γδ subsets is the human Vγ9Vδ2 T cell population, which predominates in peripheral blood and can combat both microbial infections and cancers...

RATIONALE: Late immune suppression is associated with nosocomial infection and mortality in septic adults and children. Relationships between early immune suppression and outcomes in septic children remain unclear. OBJECTIVE: Prospective observational study to test the hypothesis that early innate and adaptive immune suppression are associated with longer duration of organ dysfunction in children with severe sepsis/septic shock. Methods, Measurements and Main Results: Children aged < 18 years meeting consensus criteria for severe sepsis or septic shock were sampled within 48 hours of sepsis onset...

INTRODUCTION: Vancomycin remains the standard of care for invasive methicillin-resistant Staphylococcus aureus (MRSA) infections. Treatment failures from heteroresistant vancomycin-intermediate subpopulations (hVISA) are challenging to detect. Minimum inhibitory concentrations (MIC) identified by modified population analysis profile (PAP) is an alternative testing method. The aim of this study was to evaluate the role of PAP MIC on vancomycin failures in two high inoculum infections: MRSA infective endocarditis and pneumonia...

PURPOSE: To evaluate the correlation between the presence of bladder debris on ultrasound and urinalysis results in the emergency department setting. METHODS: Adult patients presenting to the emergency department with an ultrasound of the bladder and a urinalysis performed within 24 h of the ultrasound were included in this retrospective study. Two radiologists in consensus evaluated for the presence or absence of debris within the bladder. Urinalysis results were recorded including continuous variables (specific gravity and pH) and categorical variables (presence of occult blood, bilirubin, ketones, glucose, protein, urobilinogen, nitrite, leukocyte esterase, white blood cells, and red blood cells)...

HIV-1-infected cells persist indefinitely despite the use of combination antiretroviral therapy (ART), and novel therapeutic strategies to target and purge residual infected cells in individuals on ART are urgently needed. Here, we demonstrate that CD4+ T cell-associated HIV-1 RNA is often highly enriched in cells expressing CD30, and that cells expressing this marker considerably contribute to the total pool of transcriptionally active CD4+ lymphocytes in individuals on suppressive ART. Using in situ RNA hybridization studies, we show co-localization of CD30 with HIV-1 transcriptional activity in gut-associated lymphoid tissues...

BACKGROUND: Control of hepatitis C virus infection (HCV) is an increasingly important issue. Enhancing screening coverage is necessary to discover more HCV infected subjects in community. However, a substantial population is unaware of HCV infection that needs more attention. AIM: The aims of this study were to evaluate the status of HCV infected residents in remote villages, to compare characteristics between already known and unaware HCV infection subjects, and to analyze the disease insights...

Innovative human immunodeficiency virus (HIV) testing services will be needed to achieve the first 90 (90% of HIV-positive persons aware of their infection status) of the 90-90-90 target in China. Here, we describe an internet-based urine delivery testing service delivered through three pilot drugstores in Beijing that send specimens to a designated laboratory for HIV. From May 2016 to January 2017, we provided 500 HIV urine-testing service packs for display at the drugstores, and a total of 430 (86.0%) urine specimens were mailed back...

Preterm infants have increased risk of neonatal sepsis, potentially inducing brain injury, and they may benefit from early initiation of enteral milk feeding. Using preterm pigs as models, we hypothesized that early provision of bovine colostrum to parentally nourished newborns protects against sepsis and neuroinflammation during bloodstream infection. Preterm newborn pigs were administered 10 CFU/kg of intra-arterial Staphylococcus epidermidis (SE, an opportunistic pathogen often causing sepsis in preterm infants), followed by administration of total parenteral nutrition (TPN, SE + TPN, n = 15) or oral provision of bovine colostrum with supplementary parenteral nutrition (SE + COL, n = 14), and compared with uninfected, TPN-nourished controls (CON + TPN, n = 11)...

BACKGROUND: The successful development of immunosuppressive agents has paradoxically led to an era in which adverse effects of immunosuppression, such as infections and cancer, are now a major concern in solid organ recipients. Nevertheless, the main focus of immune monitoring research remains the identification of rejection. There is currently no clinical tool to assess the net state of immunosuppression or to identify patients at increased risk of infectious complications. METHODS: We report a prospective, longitudinal study in which we conducted detailed phenotyping of over 300 peripheral blood mononuclear cell samples from 45 kidney recipients during the first 24 months posttransplant...
