The 2'5'-oligoadenylate synthetase (OAS) is an interferon (IFN)-induced protein that plays an important role in the antiviral action of IFN, with OAS3 being one of the four OAS classes (OAS1, OAS2, OAS3, OASL). The effect of OAS on several infectious viral diseases has been reported; however, a study of the effect of OAS3 on enterovirus 71 (EV71) is lacking. The purpose of this study was to evaluate the association of the OAS3 rs1859330 G/A genetic polymorphism with susceptibility and severity of EV71 infection...

We describe pharmacokinetic and pharmacodynamic properties of two novel oral drug candidates for asthma. Phenolic α4β3γ2 GABAAR selective compound 1 and acidic α5β3γ2 selective GABAAR positive allosteric modulator compound 2 relaxed airway smooth muscle ex vivo and attenuated airway hyperresponsiveness (AHR) in a murine model of asthma. Importantly, compound 2 relaxed acetylcholine contracted human tracheal airway smooth muscle strips. Oral treatment of compound 1 and 2 decreased eosinophils in bronchoalveolar lavage fluid in ovalbumin sensitized and challenged mice, thus exhibiting anti-inflammatory properties...

REVIEW
Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

Extreme hypertriglyceridemia is rare in the neonatal period. We report a neonate with lipoprotein lipase (LPL) deficiency who presented with diagnostic and management conundrum. A full-term 36-day-old female was noted to have "Pepto-Bismol like" blood when repeating a newborn screening. The initial plasma triglyceride level was 24,318 mg/dL. The laboratory tests revealed serum bicarbonate level of <5 mmol/L, sodium of 127 mmol/L, and severe anemia. There were no signs of acute distress. The point of care capillary blood testing, however, demonstrated normal serum pH (7...

Wan Salman Wan Saudi, Markus Sjöblom
Short-chain fatty acids (SCFAs) are produced by bacterial fermentation in the large intestine, particularly from diets containing fibres and carbohydrates. The small intestinal epithelium is exposed to SCFAs derived mainly from oral bacteria or food supplementation. Although luminal nutrients are important in regulation of intestinal functions the role of SCFAs in regulation of small intestinal mucosal barrier function and motility has not been fully described. The aim of the present study was to elucidate the effects of acetate and propionate on duodenal mucosal barrier function and motility...

A previously well 25-year-old man presented with agitation, double incontinence and left-sided incoordination. His symptoms started after smoking a synthetic cannabinoid (black mamba) 5 days earlier. Over 48 hours, he developed aphasia, generalised hypertonia, hyper-reflexia and dense left hemiparesis. This progressed to profuse diaphoresis, fever, tachycardia, hypertension and a possible seizure necessitating admission to the intensive care unit. CT head and cerebrospinal fluid analysis were unremarkable...

Laboratory testing for drugs of abuse has become standard practice in many settings both forensic and clinical. Urine is the predominant specimen, but other specimens are possible including hair, nails, sweat, and oral fluid. Point-of-care test kits provide for rapid analysis at the site where specimens are collected allowing for immediate action on the results. POCT is based on immunochromatography where the drug in the patient's sample competes with drug and antibody conjugates in the test to develop or block the development of a colored line...

The kinetics of CMV DNA in infected asymptomatic hosts are largely unknown. We measured viral load (VL) in 124 fluid samples (oral, urine, vaginal, blood) collected from 21 women who acquired CMV. A quantitative real-time PCR of US17, which correlated with clinical assays, was used. VL decreased following primary infection in all fluids. The geometric mean VL of vaginal fluid was significantly higher than that of other sources: oral (3.89 95% CI [1.43 - 10.57]), urine (6.36 95% CI [2.48 - 16.32]) and whole blood (11...

Is non-response to maintenance treatment for recurrent vulvovaginal candidosis (RCVV) related to the impaired glucose metabolism? In the ReCiDiF trial, women with RCVV were given a degressive regimen with fluconazole according to their clinical, microscopic and mycologic response. Data obtained from optimal, suboptimal and non-reponding patients were used for secondary analysis of medical history, physical status and family history for potential glucose impairment. Results were presented in means and percentages...

BACKGROUND: Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). OBJECTIVE: To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms...

Mycoplasma hyorhinis is one of the causative agents of polyserositis and arthritis in postweaning pigs. Knowledge regarding colonisation frequency and age distribution in modern pig production is lacking. The objective of this study was to estimate the prevalence of M hyorhinis colonisation in different age groups across three commercial pig populations. Nasal swabs were collected from sows, piglets and nursery pigs of different ages. Oral fluids were collected from nursery pigs. Necropsies were performed to assess the presence of M hyorhinis-associated disease...

Idiopathic pulmonary fibrosis (IPF) is a life-threatening disease without effective treatment, highlighting the need for identifying new targets and treatment modalities. The pathogenesis of IPF is complex, and engaging multiple targets simultaneously might improve therapeutic efficacy. To assess the role of the endocannabinoid/cannabinoid receptor 1 (endocannabinoid/CB1R) system in IPF and its interaction with inducible nitric oxide synthase (iNOS) as dual therapeutic targets, we analyzed lung fibrosis and the status of the endocannabinoid/CB1R system and iNOS in mice with bleomycin-induced pulmonary fibrosis (PF) and in lung tissue and bronchoalveolar lavage fluid (BALF) from patients with IPF, as well as controls...

Actinomycosis is caused by the Gram positive filamentous Actinomyces bacterial species that are normal commensals of the oral cavity. Due to their low virulence, disease is rare in the immune competent patient. Although it may afflict any system in the body, involvement of the musculoskeletal system is uncommon. Here in, we describe the case of a 60 year old lady presenting with low grade fever, left hip pain and drowsiness. She was diagnosed as left hip actinomycosis on Computed tomogram (CT) guided biopsy and histopathological analysis of infiltrative lesions identified on Magnetic Resonance Imaging (MRI)...
