Epilepsy is more than seizures and includes a high risk of comorbidities and psychological disorders, leading to poor quality of life (QOL). Earlier studies have showed a sedentary lifestyle in people with epilepsy (PWE), which could contribute to poorer health and psychological problems. The purpose of the present study was to compare habits of physical activity (PA), aerobic capacity, and QOL between PWE and healthy controls in order to identify the necessity of intervention of habits and information on physical exercise (PE) and to better understand the importance of PE for PWE...

PURPOSE: Circulating tumor cells (CTCs) are considered potential biomarkers for the detection of hepatocellular carcinoma (HCC). Many studies have attempted to explore this role, but the results are variable. We conducted the first comprehensive meta-analysis to evaluate the diagnostic value of CTC assay for HCC patients. Additional prognostic value was also assessed. EXPERIMENTAL DESIGN: All articles included in our study were assessed using QUADAS guidelines after a literature search...

Memory retrieval involves the reactivation of processes that were engaged at encoding. Using a Generalized Linear Model to test for effects of valence, our prior study suggests that memory for information previously encoded in a negative context reengages sensory processing regions at retrieval to a greater extent than positive. Here, we used partial least squares analyses of the same dataset to determine whether this valence-specific processing was one of the dominant patterns in the retrieval data. Trials previously paired with a face revealed a strong pattern of emotion that did not vary by valence, but for trials previously paired with a scene, an extensive network of regions was active during recollection of trials paired with negative content...

OBJECTIVE: To evaluate, among adolescents 10-17 years with an incident hypertensive BP (≥95(th) percentile) at a primary care visit, whether TeenBP, a novel electronic health record (EHR) linked clinical decision support tool (CDS), improved recognition of elevated BP and return for follow-up BP evaluation. METHODS: We conducted a pragmatic cluster randomized trial in 20 primary care clinics in a large Midwestern medical group. Ten clinics received the TeenBP CDS, including an alert to remeasure a hypertensive BP at that visit, an alert that a hypertensive BP should be repeated in 1-3 weeks and patient-specific order sets...

BACKGROUND: Firearm injuries disproportionately affect young, male, non-White populations, causing substantial individual and societal burden. Annual costs for hospitalized firearm injuries have not been widely described, as most previous cost studies have focused on lifetime costs. We examined a nationally-representative database of hospitalizations in the US to estimate per-hospital and overall hospital costs for firearm injuries by intent, type of weapon, and payer source. METHODS: We conducted a retrospective cohort study of all firearm injury hospitalizations in the National Inpatient Sample from 2003 through 2013...

Diabetes is a costly, chronic disease that is becoming increasingly prevalent worldwide. Studies show that Native Hawaiians suffer from higher rates of diabetes and lower rates of medication adherence compared to Caucasians and Japanese. This study compared total annual healthcare expenditures of patients with diabetes in Hawai'i by race and ethnicity and determined whether any existing differences persisted after controlling for medication adherence and demographic factors. The study population consisted of 30,445 individuals, using administrative claims data from a large health plan in Hawai'i...

BACKGROUND: Despite accumulating evidence about the harm of polypharmacy in family medicine, few studies have investigated factors related to polypharmacy. The objective of this study was to explore factors related to physicians' prescribing behavior. METHODS: We conducted a survey of physicians at 5 family medicine residency practices and a linked health record review of their patients ≥65 years old. The determinants of physicians' mean number of prescriptions and potentially inappropriate medications (PIMs) were examined using a generalized linear model...

INTRODUCTION: Musculoskeletal (MSK) complaints are the second most common reason for a hospital outpatient appointment in the US, and account for 19.5% of general practice consultations. Previous studies have shown that passive teaching in medical school does not imbue students with an adequate degree of confidence in MSK evaluation. The aim of this study was to conduct a randomized control trial to compare the effect of the gold standard small group tutorial of bedside teaching against case-based teaching (CBT) in relation to orthopedic surgery in medical students...

We investigate the formation of chains of few plasmonic nanoparticles - so called plasmonic oligomers - by strain induced fragmentation of linear particle assemblies. Detailed investigations of the fragmentation process are conducted by in-situ atomic force microscopy (AFM) and UV-vis-NIR spectroscopy. Based on these experimental results and mechanical simulations computed by the lattice spring model (LSM), we propose a formation mechanism which explains the observed decrease of chain polydispersity upon increasing strain and provides experimental guidelines for tailoring chain length distribution...

BACKGROUND: Identification of the Mycobacterium tuberculosis immunoproteome and antigens associated with serologic responses in adults has renewed interest in developing a serologic test for childhood tuberculosis (TB). We investigated IgG antibody responses against M. tuberculosis antigens in children with well-characterized TB. METHODS: We studied archived sera obtained from hospitalized children with suspected pulmonary TB, and classified as having confirmed TB (culture-confirmed), unlikely TB (clinical improvement without TB treatment), or unconfirmed TB (all others)...

Extreme climatic events affecting the Amazon region are expected to become more frequent under ongoing climate change. In this study, we assessed the responses to the 2010 drought of over 14,000 trees ≥ 10 cm dbh in a 25 ha lowland forest plot in the Colombian Amazon and how these responses varied among topographically defined habitats, with tree size, and with species wood density. Tree mortality was significantly higher during the 2010-2013 period immediately after the drought than in 2007-2010. The post-drought increase in mortality was stronger for trees located in valleys (+243%) than for those located on slopes (+67%) and ridges (+57%)...

Jaeshin Kim, Shihe Xu
The accurate understanding of the fate of volatile methylsiloxanes (VMS) in air is crucial in determining persistence and concentrations in the environment. Although oxidation by atmospheric hydroxyl radicals (oOH) is considered as a major degradation mechanism for airborne VMS, the existing bimolecular rate constants with •OH measured and modeled for any given VMS compound varied greatly, depending on the approaches used to generate the data. The objectives of this study were to measure •OH reaction rate constants for four cyclic and four linear VMS based on a relative rate method using a newly designed atmospheric chamber and to establish structure-reactivity relationships for the kinetics...

Undergraduate research experiences are a "high impact" educational practice that confer benefits to students. However, little attention has been paid to understanding faculty motivation to mentor undergraduate students through research training programs, even as the number of programs has grown, requiring increasing numbers of faculty mentors. To address this, we introduce a conceptual model for understanding faculty motivation to mentor and test it by using empirical data to identify factors that enable and constrain faculty engagement in an undergraduate research program...
