PURPOSE: Although teenage birth rates in America have fallen to a historic low of 26.2 births per 1,000 teenagers, the U.S. remains behind the rest of the industrialized world. Adolescent pregnancy is relatively well discussed in today's literature, with ever more detailed estimates constantly emerging to quantify the cost of children born to America's teenagers. This study, however, describes the financial cost of childbirth in the U.S. with a specific focus on understanding the impact of adolescent childbirth in comparison to that of adult women and of annual childbirth as a whole...

Honeybee losses have been attributed to multiple stressors and factors including the neonicotinoid insecticides (NIs). Much of the study of hive contamination has been focused upon temperate regions such as Europe, Canada and the United States. This study looks for the first time at honey, pollen and bees collected from across the Nile Delta in Egypt in both the spring and summer planting season of 2013. There is limited information upon the frequency of use of NIs in Egypt but the ratio of positive identification and concentrations of NIs are comparable to other regions...

This study aimed to investigate the consequences of maternal exposure to iodine excess (IE; 0.6 mg NaI/L) throughout pregnancy and lactation on the hypothalamus-pituitary-thyroid axis of the male offspring in adulthood. Maternal IE exposure increased hypothalamic Trh mRNA expression and pituitary Tsh expression and secretion in the adult male offspring. Moreover, the IE-exposed offspring rats presented reduced thyroid hormones levels, morphological alterations in the thyroid follicles, increased thyroid oxidative stress and decreased expression of thyroid differentiation markers (Tshr, Nis, Tg, Tpo, Mct8) and thyroid transcription factors (Nkx2...

BACKGROUND: Israel hosts approximately 50,000 asylum seekers, most of them from Eritrea. Exclusive policies restrict their access to healthcare. In 2013, local activists partnered with Eritrean asylum seekers to assess health needs as well as willingness to pay for health insurance among the Eritrean communities. This initiative was meant as a step towards jointly advocating access to Israel's public healthcare system and towards strengthening collective efficacy among the asylum-seeking communities, as well as a first attempt to apply a community-based participatory research (CBPR) approach to migrant health research in Israel...

We investigate the performance of multi-configuration pair-density functional theory (MC-PDFT) and complete active space second-order perturbation theory for computing the bond dissociation energies of the diatomic molecules FeC, NiC, FeS, NiS, FeSe, and NiSe, for which accurate experimental data have become recently available [Matthew, D. J.; Tieu, E.; Morse, M. D. J. Chem. Phys. 2017, 146, 144310]. We use three correlated participating orbitals (CPO) schemes (nominal, moderate, and extended) to define the active spaces (CAS), and we consider both the complete active space (CAS) and the separated-pair (SP) schemes to specific the configurations included for a given active space...

PURPOSE: Paroxysmal supraventricular tachycardia (PSVT) ablation can result in injury to the atrioventricular (AV) node causing complete heart block requiring permanent pacemaker (PPM) implantation. Few studies have examined the impact of hospital PSVT ablation volume and PPM implantation rates post ablation. METHODS: We included adult patients from the Nationwide Inpatient Sample (NIS) database, from 1998 to 2011, using ICD-9 diagnoses codes 427.0 and 427.89 for PSVT and ICD-9 procedure code 37...

Several apical iodide translocation pathways have been proposed for iodide efflux out of thyroid follicular cells, including a pathway mediated by the sodium-coupled monocarboxylate transporter 1 (SMCT1), which remains controversial. Herein, we evaluate structural and functional similarities between SMCT1 and the well-studied sodium-iodide symporter (NIS) that mediates the first step of iodide entry into the thyroid. Free-energy calculations using a force field with electronic polarizability verify the presence of a conserved iodide-binding pocket between the TM2, TM3, and TM7 segments in hNIS, where iodide is coordinated by Phe67, Gln72, Cys91, and Gln94...

BACKGROUND: Relenza represents the first neuraminidase inhibitor (NI), a class of drugs that also includes the drug Tamiflu. Although heralded as breakthrough treatments in influenza, NI efficacy has remained highly controversial. A key unsettled question is why the United States Food and Drug Administration (FDA) has approved more cautious efficacy statements in labelling than European regulators for both drugs. METHODS: We conducted a qualitative analysis of United States and European Union regulatory appraisals for Relenza to investigate the reasons for divergent regulatory interpretations, pertaining to Relenza's capacity to alleviate symptoms and reduce frequency of complications of influenza...

This research looked at Biba: a suite of mobile games intended to get kids back out to playgrounds and engaging in more moderate to vigorous physical activity (MVPA). Year after year, annual national surveys report a general decline in physical activity amongst children and a corresponding increase in screen time. Further to this, time spent outside by children has been reported to be on the decline since the 1980s. Recent work has suggested that in order to 'maintain the outdoor recreation participation of children across America, park and recreation professionals may need to embrace the expanding role of technology'...

Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) accounts for 5% of all strokes; 30-day mortality is as high as 40%. We sought to evaluate outcomes of aSAH patients treated 2004-2014 by endovascular therapy (EVT), to demonstrate associated trends, and to evaluate angioplasty use for aSAH-related cerebral vasospasm. Methods: The Nationwide Inpatient Sample (NIS) database 2004-2014 was used to derive a study cohort using ICD-9 codes. Survey procedures were used to adjust for stratified cluster design of NIS...

BACKGROUND: To better characterize the effects of tafamidis in non-Val30Met patients with transthyretin familial amyloid polyneuropathy, this post-hoc analysis compared the neurologic results from a 12-month, open-label study of non-Val30Met vs. Val30Met patients at Month 12 from the 18-month, double-blind, placebo-controlled registration study. A baseline covariate adjusted analysis was used to control for differences in baseline neurologic severity. METHODS: Neurologic function was assessed using the Neuropathy Impairment Score-Lower Limbs (NIS-LL) in three cohorts: Val30Met tafamidis (n = 64), Val30Met placebo (n = 61) and non-Val30Met tafamidis (n = 21)...

Na(+) /I(-) symporter (NIS) transports iodide into thyrocytes, a fundamental step for thyroid hormone biosynthesis. Our aim was to evaluate NIS regulation in different status of goitrogenesis and its underlying mechanisms. Wistar rats were treated with methimazole (MMI) for 5 and 21 days, to achieve different status of goiter. We then evaluated the effect of MMI removal for 1 day (R1d), after 5 (R1d-5d) or 21 (R1d-21d) days of MMI treatment. MMI increased thyroid weight, iodide uptake and in vitro TPO activity in a time-dependent way...

Non-ionic surfactant (NIS) based in situ forming vesicles (ISVs) present an affordable alternative to the traditional systems for the parenteral control of drug release. In this work, NIS based ISVs encapsulating tenoxicam were prepared using the emulsion method. Tenoxicam-loaded ISVs were prepared using a 2(2).3(1) full factorial experimental design, where three factors were evaluated as independent variables; type of NIS (A), molar ratio of NIS to Tween®80 (B), and phase ratio of the internal ethyl acetate to the external Captex® oil phase (C)...

Radiopharmaceuticals incorporating radioactive iodine in combination with SPECT imaging play a key role in nuclear medicine, with applications in drug development and disease diagnosis. Despite this importance, there are relatively few general methods for incorporating radioiodine into small molecules. Here we describe a rapid, air- and moisture-stable ipso-iododeboronation procedure using NIS, in the non-toxic and green solvent dimethyl carbonate. The fast reaction and mild conditions of the gold-catalysed method led to the development of a highly efficient process for radiolabelling of arenes, which constitutes the first example of an application of homogenous gold catalysis to selective radiosynthesis...

We consider settings where it is of interest to fit and assess regression submodels that arise as various explanatory variables are excluded from a larger regression model. The larger model is referred to as the full model; the submodels are the reduced models. We show that a computationally efficient approximation to the regression estimates under any reduced model can be obtained from a simple weighted least squares (WLS) approach based on the estimated regression parameters and covariance matrix from the full model...
