OBJECTIVE: While pre-exposure prophylaxis with oral tenofovir (TFV) disoproxil fumarate/emtricitabine reduces HIV acquisition rates, poor adherence to and acceptability of daily vaginal gels has led to development of vaginal film formulations to improve adherence and, potentially, enable episodic use. STUDY DESIGN: In this two-arm, cross-over study of a fast-dissolving tenofovir film (40 mg) compared to a previously studied semisolid tenofovir 1% gel (40 mg), 10 healthy women received a single vaginal dose of each study product...

BACKGROUND: Data on the typical time point of occurrence of anastomotic leak (AL) after esophagectomy for esophageal cancer are currently scarce. Therefore, the usefulness of routine radiocontrast agent studies (RRCS) for testing proper healing of the anastomosis after esophagectomy remains unclear. Furthermore, preferred available tools to diagnose postoperative AL and therapeutic options are still under debate. METHODS: We present a retrospective analysis of 328 consecutive patients who underwent esophagectomy for esophageal cancer between 2005 and 2015...

PCR is a universal tool for the multiplication of specific DNA sequences. For example, PCR-based sex determination is widely used, and a diversity of primer sets is available. However, this protocol requires thermal cycling and electrophoresis so results are typically obtained in laboratories and several days after sampling. Loop-mediated isothermal amplification (LAMP) is an alternative to PCR that can take molecular ecology outside the laboratory. Although its application has been successfully probed for sex determination in three species of a single avian Family (Raptors, Accipitridae), its generality remains untested and suitable primers across taxa are lacking...

OBJECTIVE: Acute ischemic stroke (AIS) is an important global health problem. Intravenous (IV) thrombolysis with recombinant tissue plasminogen activator (rt-PA) is the standard treatment. However, only a small number of patients benefit from it because of strict application restrictions. Increasing evidence has demonstrated that mechanical thrombectomy is an effective and safe therapy for AIS. PATIENTS AND METHODS: We present 14 cases of successful recanalization with Solitaire devices for AIS patients after stroke onset...

Arsenic, often referred to as the king of poisons is carcinogenic in humans and animals. It affects multiorgan systems including reproduction. The present study was undertaken to explore the protective role of green tea compound, epigallocatechin-3-gallate (EGCG) on arsenic induced testicular toxicity in Swiss albino mice. Thirty two adult male mice were randomly assigned to four groups (n=8). Group I served as control without test chemical. The group II received arsenic (200ppm) through drinking water, group III received only EGCG (20mg/kgb...

The etiology of temporomandibular disorders (TMD), which are considered as a heterogeneous group of psychophysiological disturbances, remains a controversial issue in clinical dentistry. This study aimed to evaluate whether the salivary alpha-amylase (sAA), cortisol levels, and anxiety symptoms differ between children with and without TMD. Initially, 316 young subjects were screened in public schools (nonreferred sample); 76 subjects aged 7-14 years were selected and comprised the TMD and control groups with 38 subjects each matched by sex, age, and the presence/absence of sleep bruxism...

Determination of trimethylamine N-oxide (TMAO) and trimethylamine (TMA) in biological and environmental samples has drawn great attention recently due to their increasing association with human health and disease. It remains a challenge to simultaneously quantify TMAO and TMA in a simple, fast and cost-effective manner due to pre-analytical and analytical constraints. For the first time, we describe a dilute and shoot approach combined with LC-MS/MS detection for the simultaneous measurement of the analytes in spot urine samples with high throughput...

INTRODUCTION: Defining the boundary of children's 'neighborhoods' has important implications for understanding the contextual influences on child health. Additionally, insight into activities that occur outside people's neighborhoods may indicate exposures that place-based studies cannot detect. This study aimed to 1) extend current neighborhood research, using data from wearable cameras and GPS devices that were worn over several days in an urban setting; 2) define the boundary of children's neighborhoods by using leisure time activity space data; and 3) determine the destinations visited by children in their leisure time, outside their neighborhoods...

BACKGROUND AND PURPOSE: Head CT is the current neuroimaging tool of choice in acute evaluation of pediatric head trauma. The potential cancer risks of CT-related ionizing radiation should limit its use in children. We evaluated the role of MR imaging, including a "black bone" sequence, compared with CT in detecting skull fractures and intracranial hemorrhages in children with acute head trauma. MATERIALS AND METHODS: We performed a retrospective evaluation of 2D head CT and brain MR imaging studies including the black bone sequence of children with head trauma...

INTRODUCTION: Current clinical practice guidelines suggest that patients with ulcerative colitis (UC) hospitalized because of a disease flare should be offered a normal diet, unless such a diet is not tolerated. Studies of hospitalized patients have demonstrated iatrogenic malnutrition from unjustified or inappropriate nil per os (NPO) or clear liquid diet (CLD) orders. In this study, we aim to characterize the burden of this problem in hospitalized patients with UC. METHODS: We conducted a retrospective cohort study of all patients with UC admitted to the gastroenterology service or the general internal medicine service at a tertiary, academic hospital between January 2009 and December 2014, with a length of stay between 2 and 30 days...

BACKGROUND: There is an increasing interest among nutritional researchers to perform lifestyle and nutritional intervention studies in a home setting instead of testing subjects in a clinical unit. The term used in other disciplines is 'ecological validity' stressing a realistic situation. This becomes more and more feasible because devices and self-tests that enable such studies are more commonly available. Here, we present such a study in which we reproduced the effect of caffeine on attention and alertness in an at-home setting...

Mandelic acid (MA) is a major metabolite of ethylbenzene and styrene. For the first time, a selective, fast, and easy-to-use procedure was developed for the determination of MA in urine samples. The new procedure is based on MIMEPS, the combination of a molecularly imprinted polymer (MIP) and microextraction by packed sorbent (MEPS). High-performance liquid chromatography with ultraviolet detection (HPLC-UV) was used for the separation and determination of MA. The bulk polymerization method was used to synthesize the MIP, and the MIP and non-imprinted polymer (NIP) were characterized by Fourier transform infrared spectroscopy...
