INTRODUCTION: Frailty, a clinical syndrome of decreased physiologic reserve and dysregulation in multiple physiologic systems, is associated with increased risk for adverse outcomes. PURPOSE: The aim of this retrospective, cross-sectional, correlational study was to characterize frailty in older adults admitted to a tertiary-care hospital using a biopsychosocial frailty assessment and to determine associations between frailty and time to in-hospital mortality and 30-day rehospitalization...

There is a limited number of publications on the bioavailability and digestibility of nutrients contained in macrofungi. The aim of this study was to assess the bioavailability and digestibility of macronutrients using in vivo experiments on laboratory animals. The experiments were conducted with the commercial oyster mushroom Pleurotus ostreatus. Semisynthetic diets were prepared based on the modified AIN-93M diet and were supplemented with 4% and 8% mushroom powder. Between days 4 and 13, apparent digestibility indexes were determined for all animals using the conventional balance method...

INTRODUCTION: The tree Trichilia catigua, popularly known as "catuaba", shows several biological activities and has emerged as a potential source of new drugs. Considering that more than 10 species are known under the same popular name, regulatory agencies require more rigorous quality control of this medicinal plant. OBJECTIVE: To develop and validate a methodology using capillary electrophoresis (CE) with ultraviolet (UV) detection for analysing polyphenols in the ethyl-acetate fraction (EAF) of Trichilia catigua...

Hans-Sonke Jans
PURPOSE: To present and evaluate an ion chamber-based method for the cross-calibration between sites of activity measurements of unsealed radionuclides. Notably, the method allows direct comparison of short lived (i.e., clinically used) radioisotopes and the cross-calibration of radionuclide activity meters (also known as "dose calibrators"). METHODS: A portable ion chamber has been designed which is easily shipped between sites, e.g., between a standards laboratory and a nuclear medicine department...

We here propose the implementation of a simple and effective method to enhance the quality of basic and preclinical academic research: critical incident reporting (CIR). CIR has become a standard in clinical medicine but to our knowledge has never been implemented in the context of academic basic research. We provide a simple, free, open-source software tool for implementing a CIR system in research groups, laboratories, or large institutions (LabCIRS). LabCIRS was developed, tested, and implemented in our multidisciplinary and multiprofessional neuroscience research department...

Child sexual abuse is a worldwide public health issue. The objective of this study was to describe the demographic and clinical characteristics of children in cases of sexual abuse confirmed by material evidence at forensic examination. Cases of children younger than 12 years examined for suspected sexual abuse at the Institute of Forensic Medicine in Salvador, Bahia, Brazil, were reviewed retrospectively. The period evaluated was between 2005 and 2010. The inclusion criterion was the coroner's confirmation of sexual abuse based on material evidence...

Stephen Thomas, Kayleen Jahangir
Clinical data such as history, physical examination, and laboratory tests are useful in identifying patients with biliary obstruction and biliary sources of infection. However, if intervention is planned, noninvasive imaging is needed to confirm the presence, location, and extent of the disease process. Currently, the most commonly available and used noninvasive modalities are ultrasound (US), computed tomography (CT), magnetic resonance (MR), and nuclear medicine hepatobiliary scintigraphy (HIDA). US is quick, portable, readily available, and is commonly the first imaging modality used when biliary pathology is suspected...

BACKGROUND: Platelet-rich plasma (PRP) is widely used in sports medicine. Available PRP preparations differ in white blood cell, platelet, and growth factor concentrations, making standardized research and clinical application challenging. PURPOSE: To characterize a newly standardized procedure for pooled PRP that provides defined growth factor concentrations. STUDY DESIGN: Controlled laboratory study. METHODS: A standardized growth factor preparation (lyophilized PRP powder) was prepared using 12 pooled platelet concentrates (PCs) derived from different donors via apheresis...

BACKGROUND: Atopic dermatitis (AD) is a common inflammatory skin disease with an increasingly significant prevalence. The prevalence of AD depends greatly on how its diagnosis is done. The UK Working Party's diagnostic criteria for AD are simple and easy to apply without invasive laboratory tests. This study assessed the clinical utility of these criteria in China. METHODS: Data were collected from 6208 patients at 31 tertiary hospitals in 13 Chinese provinces/municipalities from March 2014 to May 2014...

BACKGROUND: Recovery from exercise and competition is important in sports medicine, particularly when rest periods are short. The objective is to determine the efficacy of cryo exposition (CRY) and manual lymphatic drainage (MLD) to hasten short term recovery of muscle performance after eccentric contractions. METHODS: In a randomized controlled trial, 30 healthy sport students (21 males, 9 females; age: 25.7±2.8 years) performed 4×20 eccentric contractions of knee extensors, followed by 30 min MLD, CRY, or rest (RST) under controlled laboratory environment...

Celastrus orbiculatus is used as a folk medicine in China for the treatment of numerous diseases. The ethyl acetate extract of Celastrus orbiculatus (COE) also displays a wide range of anti-cancer activities in the laboratory. However, the effectiveness of COE-induced autophagy and its mechanism of action in colorectal cancer cells have not been investigated thus far. The present study analyzed the effect of COE on HT-29 cell viability, apoptosis and autophagy using MTT assay, flow cytometry, transmission electron microscopy and western blotting...

Current laboratory testing of Lyme borreliosis mostly relies on serological methods with known limitations. Diagnostic modalities enabling direct detection of pathogen at the onset of the clinical signs could overcome some of the limitations. Molecular methods detecting borrelial DNA seem to be the ideal solution, although there are some aspects that need to be considered. Areas covered: This review represent summary and discussion of the published data obtained from literature searches from PubMed and The National Library of Medicine (USA) together with our own experience on molecular diagnosis of Lyme disease...

BACKGROUND: The birth defects component of the Western Australian Register for Developmental Anomalies (WARDA-BD) was evaluated to assess its efficiency, effectiveness, and data quality. METHODS: WARDA-BD was evaluated using the Centers for Disease Control and Prevention Guidelines for Evaluating Public Health Surveillance Systems and Data Quality Standards from the National Birth Defects Prevention Network. The evaluation included interviews with Register staff, local community organizations, parents, clinicians, and researchers; process observation; and secondary data analyses...

Venipuncture is one of the most commonly done medical procedures. We report a unique case of a 23-year-old young male who presented with features suggestive of inflammatory arthritis. The symptoms, which initially started on the right side, also involved the other side after a few weeks. Although the patient's symptoms and signs were simulating inflammatory arthritis, he had atypical features like poor response to anti-inflammatory medicines and normal laboratory parameters. His musculoskeletal ultrasonography was also not suggestive of arthritis...

BACKGROUND: Enteric fever's incidence is decreasing among residents of high-income countries, although it's rising in travelers coming from low-resource endemic settings. The study's aim is to describe epidemiological, clinical and laboratory features of patients with enteric fever. METHODS: Retrospective descriptive study of enteric fever cases diagnosed at a Tropical Medicine Unit in Barcelona, 1993-2012. RESULTS: Out of 40 patients, 31(77,5%) were returning travelers, and 70% of them had been in Southern Asia...

OBJECTIVE: To develop a clinical score to predict appendicitis among older, male children who present to the emergency department (ED) with suspected appendicitis. METHODS: Patients with suspected appendicitis were prospectively recruited at 9 pediatric EDs. A total 2,625 patients enrolled; a subset of 961 males, age 8-18 were analyzed in this secondary analysis. Outcomes determined by pathology, operative reports and follow-up calls. Clinical and laboratory predictors with < 10% missing data and Kappa > 0...
