Alcohol exposure results in reduced mortality following traumatic brain injury (TBI) in animal models, yet clinical studies reported conflicting results and clinical trials based on proposed mechanisms have been disappointing. Methodological issues common to many of the clinical studies may have contributed to spurious results. Our objective was to evaluate the association between blood alcohol concentration (BAC) and in-hospital mortality following TBI, overcoming methodological problems of prior studies. We conducted a retrospective cohort study on individuals treated for isolated TBI at the R Adams Cowley Shock Trauma Center between 1997-2012 (n = 1,084)...

Chronic inflammation may be a risk factor for breast cancer development and progression, yet which inflammatory biomarkers and pathways are relevant is unknown. The study included 27,071 Women's Health Study participants (mean, 54.5 years old) free of cancer and cardiovascular disease at enrollment (1992 to 1995) with baseline measures of four inflammatory biomarkers: high sensitivity C-reactive protein (hsCRP), fibrinogen, N-acetyl side-chains of acute phase proteins (GlycA), and soluble intercellular adhesion molecule-1 (sICAM-1)...

We examined effectiveness of HPV vaccination by dose number and interval against incident genital warts in a cohort of 64,517 females in the United States during 8/2006-9/2012. Eligible females were classified into 0, 1-dose, 2-dose < 6 months apart, 2-dose ≥6 months apart, and 3-dose groups and followed until genital wart diagnosis, loss to follow-up, or end of study. Propensity score weights were used to balance baseline differences across groups. To account for latent genital warts before vaccination, 6-month and 12-month buffer periods from last and first vaccine dose, respectively, were applied...

This work proposes a new method of simulating dose reduction in digital breast tomosynthesis (DBT), starting from a clinical image acquired with a standard radiation dose. It considers both signal-dependent quantum and signal-independent electronic noise. Furthermore, the method accounts for pixel crosstalk, which causes the noise to be frequency-dependent, thus increasing the simulation accuracy. For an objective assessment, simulated and real images were compared in terms of noise standard deviation, signal-to-noise ratio (SNR) and normalized noise power spectrum (NNPS)...

Excited-state intramolecular proton transfer (ESIPT) reactions occurring in the S1 state for five molecules, which possess five/six-membered ring intramolecular NH···N or OH···N hydrogen bonds bearing quinoline or 2-phenylpyridine moiety, have been described in detail by the time-dependent density functional theory (TD-DFT) approach using the B3LYP hybrid functional. For the five molecules, the constrained potential energy profiles along the ESIPT reactions show that proton transfer is barrierless in molecules possessing six-membered ring intramolecular H-bonds, which is smoother than that with certain barriers in five-membered ring H-bonding systems...

PURPOSE: The optimal timing of endotracheal intubation in critically ill patients requiring invasive mechanical ventilation remains undefined. MATERIAL AND METHODS: In a secondary analysis of the large, prospective ICON database, we used a piecewise proportional hazards model to compare outcomes in patients who underwent intubation early (within two days after intensive care unit [ICU] admission) or later. RESULTS: After excluding 5340 patients already intubated on admission or with therapeutic limitation, 4729 patients were analyzed, of whom 4074 never underwent intubation...

Recently, great attention has been paid to the identification and prediction of the androgen disrupting potencies of polybrominated diphenyl ethers (PBDEs). However, few existing models can discriminate active and inactive compounds, which make the quantitative prediction process including the quantitative structure-activity relationship (QSAR) technique unreliable. In this study, different grouping methods were investigated and compared for qualitative identification, including molecular docking and molecular dynamics simulations (MD)...

AIM: Capillarity theory predicts that the pore volume infiltrated by a liquid in a body with tubular capillaries is directly proportional to the capillary radius. The expected volume available for infiltration is the loosely bound water volume, which can be related to the capillary radii. We tested the hypothesis that the proportion of the pore volume infiltrated by resin infiltrant (Vratio(resin)) is correlated and agrees with the proportion of the pore volume with loosely bound water ( [Formula: see text] )...

BACKGROUND: Psychosocial stress during pregnancy has been proposed as a major contributor of glucocorticoid-mediated programming of the fetal hypothalamic-pituitary adrenal (HPA) axis, with later adverse health consequences. However, evidence linking maternal stress to maternal cortisol values during pregnancy is inconclusive. A possible explanation for this is that other maternal factors overshadow any potential effects of stress on cortisol levels. We studied a large cohort of pregnant women with extensive data on pregnancy characteristics to determine the respective contributions of biological, environmental and psychosocial stress factors to cortisol levels in pregnancy...

AIMS: Serum albumin-adjusted glycated albumin (adjusted GA) is reportedly a better predictor of mortality than GA in patients with Type 2 diabetes mellitus (T2DM) on hemodialysis (HD). We compared how accurately GA and adjusted GA reflected glycemic control in these patients. METHODS: We enrolled 31 patients with T2DM on HD. They were divided into two groups according to duration of HD: ≤6months (short HD group, N=16) and >6months (long HD group, N=15). GA or adjusted GA and parameters of glycemic control obtained by continuous glucose monitoring were measured, and the correlations between these were analyzed...

Driving under the influence of drugs (DUID) is a worldwide problem. Several countries adopted DUID legislations which prove their deterrent effect and impact on road safety. However, use of new psychoactive substances (NPS) and prescription drugs is not known as the applied roadside screening tests are not yet adapted for these compounds. In this study, 558 blood samples obtained during roadside controls in Belgium (January to August 2015) after a positive Drugwipe 5S® test and 199 oral fluid (OF) samples obtained from negatively screened test pads were analyzed...

This study investigated the required coefficient of friction (RCOF) and the tangent of center of mass (COM)-center of pressure (COP) angle in the mediolateral (ML) and anteroposterior (AP) directions during turning at different walking speeds. Sixteen healthy young adults (8 males and 8 females) participated in this study. The participants were instructed to conduct trials of straight walking and 90° step and spin turns to the right at each of three self-selected speeds (slow, normal, and fast). The ML and AP directions during turning gait were defined using the orientation of the pelvis to construct a body-fixed reference frame...
