BACKGROUND: Changes in health insurance coverage have been implicated in limiting access to care and increasing morbidity risk. The consequences of insurance discontinuity for surgical outcomes are unclear. In this study, we explored whether recent insurance discontinuity was associated with prolonged inpatient hospitalization after adenotonsillectomy in children. MATERIALS AND METHODS: We retrospectively evaluated single-center data on children aged 2-18 y undergoing adenotonsillectomy with overnight stay in 2009-2014...

This study investigated the effect of performing a preconditioning exercise with or without whole-body vibration (WBV) on a subsequent cycling sprint performance. Fourteen trained subjects performed two separate test sessions in randomized order. After a warm-up, the preconditioning exercise (body-loaded half squats) was applied: 30-seconds of half-squats with WBV (40 Hz, 2 mm) or 30-seconds of half-squats without WBV with a 10-second all-out sprint performed after one minute. Surface electromyography (EMG) was measured from the vastus medialis, vastus lateralis and gastrocnemius medialis during the sprints...

BACKGROUND: Pancreatoduodenectomy is a surgical procedure used to treat diseases of the pancreatic head and, less often, the duodenum. The most common disease treated is cancer, but pancreatoduodenectomy is also used for people with traumatic lesions and chronic pancreatitis. Following pancreatoduodenectomy, the pancreatic stump must be connected with the small bowel where pancreatic juice can play its role in food digestion. Pancreatojejunostomy (PJ) and pancreatogastrostomy (PG) are surgical procedures commonly used to reconstruct the pancreatic stump after pancreatoduodenectomy...

Toxoplasma gondii is a widespread zoonotic parasite that is relevant for veterinary and public health. The domestic cat, the definitive host species with the largest worldwide population, has become evolutionarily and epidemiologically the most important host of T. gondii. The outcome of T. gondii infection is influenced by congenital and acquired host characteristics. We detected differences in T. gondii seroprevalence by cat breed in our previous studies. The aims of this study were to estimate T. gondii seroprevalence in selected domestic cat breeds, and to evaluate whether being of a certain breed is associated with T...

SETTING: Systematic screening for active pulmonary tuberculosis (PTB) is recommended for high-risk populations, including people living with the human immunodeficiency virus (PLHIV); however, currently recommended TB screening tools are inadequate for most high-burden settings. OBJECTIVE: To determine whether C-reactive protein (CRP) possesses the necessary test characteristics to screen individuals for active PTB. DESIGN: We performed a systematic review and meta-analysis of studies evaluating the diagnostic accuracy of CRP (10 mg/l cut-off point) for culture-positive PTB...

Elevated [CO2] (e[CO2]) environments have been predicted to improve rice yields under future climate. However, a concomitant rise in temperature could negate e[CO2] impact on plants, presenting a serious challenge for crop improvement. High temperature (HT) stress tolerant NL-44 and high yielding basmati Pusa 1121 rice cultivars, were exposed to e[CO2] (from panicle initiation to maturity) and a combination of e[CO2] + HT (from heading to maturity) using field based open top chambers. Elevated [CO2] significantly increased photosynthesis, seed-set, panicle weight and grain weight across both cultivars, more prominently with Pusa 1121...

The Linguistic Atlas of the Gulf States is an extensive audio corpus of sociolinguistic interviews with 1121 speakers from eight southeastern U.S. states. Complete interviews have never been fully transcribed, leaving a wealth of phonetic information unexplored. This paper details methods for large-scale acoustic analysis of this historical speech corpus, providing a fuller picture of Southern speech than offered by previous impressionistic analyses. Interviews from 10 speakers (∼36 h) in southeast Georgia were transcribed and analyzed for dialectal features associated with the Southern Vowel Shift and African American Vowel Shift, also considering the effects of age, gender, and race...

BACKGROUND: Urinary incontinence is a very common and debilitating problem affecting about 50% of women at some point in their lives. Stress urinary incontinence (SUI) is a predominant cause in 30% to 80% of these women imposing significant health and economic burden on society and the women affected. Mid-urethral sling (MUS) operations are a recognised minimally invasive surgical treatment for SUI. MUS involves the passage of a small strip of tape through either the retropubic or obturator space, with entry or exit points at the lower abdomen or groin, respectively...

Nonalcoholic fatty liver disease (NAFLD) represents an emerging cause of hepatocellular carcinoma (HCC), especially in non-cirrhotic individuals. The rs641738 C > T MBOAT7/TMC4 variant predisposes to progressive NAFLD, but the impact on hepatic carcinogenesis is unknown. In Italian NAFLD patients, the rs641738 T allele was associated with NAFLD-HCC (OR 1.65, 1.08-2.55; n = 765), particularly in those without advanced fibrosis (p < 0.001). The risk T allele was linked to 3'-UTR variation in MBOAT7 and to reduced MBOAT7 expression in patients without severe fibrosis...

This study investigated whether passively collected routine health facility data can be used for mapping spatial heterogeneities in malaria transmission at the level of local government housing cluster administrative units in Dar es Salaam, Tanzania. From June 2012 to January 2013, residential locations of patients tested for malaria at a public health facility were traced based on their local leaders' names and geo-referencing the point locations of these leaders' houses. Geographic information systems (GIS) were used to visualise the spatial distribution of malaria infection rates...
