Gordon F West, Diana D Jeffery
OBJECTIVE: Like the general population, the military is experiencing an increase in the number of obese personnel. This study aimed to identify predictors of obesity by assessing social determinants of health and behaviors in relation to Body Mass Index (BMI), and to use these variables to build a model to predict obesity in Active Duty Military Personnel (ADMP). Predicting obesity would allow early intervention of at risk personnel, potentially reducing the number of ADMP who are separated from the service for failing to meet weight standards...

Use of vent-free gas heating appliances for supplemental heating in U.S. homes is increasing. However, there is currently a lack of information on the potential impact of these appliances on indoor air quality for homes constructed according to energy-efficient and green building standards. A probabilistic analysis was conducted to estimate the impact of vent-free gas heating appliances on indoor air concentrations of carbon monoxide (CO), nitrogen dioxide (NO2), carbon dioxide (CO2), water vapor, and oxygen in "tight" energy-efficient homes in the U...

Background: Finafloxacin is a novel fluoroquinolone with increased antibacterial activity at acidic pH and reduced susceptibility to several resistance mechanisms. A phase II study revealed a good efficacy/safety profile in patients with complicated urinary tract infections (cUTI) while pharmacokinetics was characterized by highly variable concentration vs. time profiles, suggesting the need for an elaborated pharmacokinetic model.Methods: Data from three clinical trials were evaluated; 127 healthy volunteers were dosed orally (N=77) or intravenously (N=50) and 139 patients with cUTI received finafloxacin intravenously...

The Wnt family of secreted proteins has been proposed to play a conserved role in early specification of the bilaterian anteroposterior (A/P) axis. This hypothesis is based predominantly on data from vertebrate embryogenesis as well as planarian regeneration and homeostasis, indicating that canonical Wnt (cWnt) signaling endows cells with positional information along the A/P axis. Outside of these phyla, there is strong support for a conserved role of cWnt signaling in the repression of anterior fates, but little comparative support for a conserved role in promotion of posterior fates...

BACKGROUND: Periodontitis is a chronic inflammatory disease, which affects the supporting tissues of the teeth, and without proper treatment it may lead to tooth loss. Antibiotics - dministered orally - have been widely used in the treatment of periodontitis. With the conventional administration routes, adequate drug levels cannot be reached in the periodontal pockets and oral application of antimicrobials could lead to side effects. Drug delivery systems containing antibiotics, administered at the site of infection, could possibly help eliminate pathogen bacteria and treat periodontitis...

REVIEW
M Dallacker, R Hertwig, J Mata
Findings on the relationship between family meal frequency and children's nutritional health are inconsistent. The reasons for these mixed results have to date remained largely unexplored. This systematic review and meta-analysis of 57 studies (203,706 participants) examines (i) the relationship between family meal frequency and various nutritional health outcomes and (ii) two potential explanations for the inconsistent findings: sociodemographic characteristics and mealtime characteristics. Separate meta-analyses revealed significant associations between higher family meal frequency and better overall diet quality (r = 0...

Although there are high rates of sexual problems and sexual dysfunction in adulthood (Mitchell et al., 2013), little is known about the circumstances under which problems are first experienced. A growing body of research addresses prevalence of problems in sexual functioning among adolescents and young adults, yet little is known about the meanings that young people give to these experiences or how they deal with them. We used content analysis of qualitative interviews with 53 heterosexual, sexually active Canadian adolescents (ages 18 to 21) to explore their perceptions of the sexual problems in functioning they had experienced and the strategies (if any) they used to address them over time...

There is growing interest concerning the ways in which the human body, both one's own and that of others, is represented in the developing human brain. In two experiments with 7-month-old infants, we employed advances in infant magnetoencephalography (MEG) brain imaging to address novel questions concerning body representations in early development. Experiment 1 evaluated the spatiotemporal organization of infants' brain responses to being touched. A punctate touch to infants' hands and feet produced significant activation in the hand and foot areas of contralateral primary somatosensory cortex as well as in other parietal and frontal areas...

The aim: This paper's aim is to assess the level of development and size of particular body parts and dimorphic differences with regard to body height. Methods: The research was carried out over the period of 1995-2010 on a 1,969-strong cohort of first-year students of physical education, aged 19-21. The following somatic features were measured: body height and weight, breadth of distal femoral epiphysis, breadth of distal brachial epiphysis, four skinfolds, arm circumference, and calf circumference. Using the results, the shares of endomorphy, mesomorphy, and ectomorphy were calculated as well as the mean values of particular features and their supplemental values and regression equations...

Niobium (Nb) is one of the key trace elements used to understand Earth's formation and differentiation, and is remarkable for its deficiency relative to tantalum in terrestrial rocks compared to the building chondritic blocks. In this context, the local environment of Nb in silica-rich melts and glasses is studied by in situ X-ray absorption spectroscopy (XAS) at high pressure (P) up to 9.3 GPa and 1350 K using resistive-heating diamond-anvil cells. Nb is slightly less oxidized in the melt (intermediate valence between +4 and +5) than in the glass (+5), an effect evidenced from the shift of the Nb-edge towards lower energies...

Corals, like other cnidarians, are venomous animals that rely on stinging cells (nematocytes) and their toxins to catch prey and defend themselves against predators. However, little is known about the chemical arsenal employed by stony corals, despite their ecological importance. Here, we show large differences in the density of nematocysts and whole-body hemolytic activity between different species of reef-building corals. In the branched coral Stylophora pistillata, the tips of the branches exhibited a greater hemolytic activity than the bases...

Neuroendocrine tumours (NETs) may arise throughout the body and are a highly heterogeneous, relatively rare class of neoplasms difficult to study also for the lack of disease models. Despite this, knowledge on their molecular alterations has expanded in the latest years, also building from genetic syndromes causing their onset. Pancreatic NETs (PanNETs) have been among the most studied, and research so far has outlined a series of recurring features, as inactivation of MEN1, VHL, TSC1/2 genes, and hyperactivation of the PI3K/mTOR pathway...

Radiologists in any practice setting should be prepared to use thoracic magnetic resonance (MR) imaging for noncardiac and nonangiographic applications. This begins with understanding the sequence building blocks that can be used to design effective thoracic MR imaging protocols. In most instances, the sequences used in thoracic MR imaging are adapted from protocols used elsewhere in the body. Some modifications, including the addition of electrocardiographic gating or respiratory triggering, may be necessary for certain applications...

More than 20 million babies are born with low birthweight annually. Small newborns have an increased risk for mortality, growth failure, and other adverse outcomes. Numerous antenatal risk factors for small newborn size have been identified, but individual interventions addressing them have not markedly improved the health outcomes of interest. We tested a hypothesis that in low-income settings, newborn size is influenced jointly by multiple maternal exposures and characterized pathways associating these exposures with newborn size...

The myocardial sleeve of the porcine and equine pulmonary veins were histologically investigated and reconstructed three dimensionally. Moreover, the localization of neuron cell bodies at the veno-atrial junction and alongside the myocardial sleeve was light microscopically visualized to depict the organization of nerve, myocardial and fat tissue. Finally, the presence of telocytes inside the equine pulmonary veins was demonstrated by use of transmission electron microscopy. These structures are thought to play a role in the induction of atrial fibrillation, which is frequently seen in horses, while pigs are often used as a cardiovascular model in this context...

INTRODUCTION: The Taperloc® Complete femoral stem (Zimmer Biomet, Warsaw, Indiana) builds on the widespread clinical success of the original Taperloc design used since 1982. Enhancements to the Complete design include a lowered caput-collum-diaphyseal (CCD) angle from 138° to 133° for improved offset, optimized neck taper with polished neck flats to increase range of motion, reduced distal geometry to improve proximal canal fill, and gradual off-loading that is the goal of tapered geometry...

Previous studies have reported association of multiple preoperative factors predicting clinically significant prostate cancer with varying results. We assessed the predictive model using a combination of hormone profile, serum biomarkers, and patient characteristics in order to improve the accuracy of risk stratification of patients with prostate cancer. Data on 224 patients from our prostatectomy database were queried. Demographic characteristics, including age, body mass index (BMI), clinical stage, clinical Gleason score (GS) as well as serum biomarkers, such as prostate-specific antigen (PSA), parathyroid hormone (PTH), calcium (Ca), prostate acid phosphatase (PAP), testosterone, and chromogranin A (CgA), were used to build a predictive model of clinically significant prostate cancer using logistic regression methods...

Phothermal therapy has received increasing attention in recent years as a potentially effective way for treatment of cancer. In pursuit of a more biocompatible photothermal agent, we utilize bio-safe materials-ellagic acid (EA), polyvinyl pyrrolidone (PVP) and iron element as the building blocks, and successfully fabricate homogeneous nanosized Fe-EA framework for the first time by a facile method. As expected, the novel nano-agent exhibits no obvious cytotoxicity and good hemocompatibility in vitro and in vivo...
