Background.: Hepatitis C virus (HCV) infection is the most common chronic blood-borne infection in the United States and a leading cause of morbidity and mortality. Previous analyses of the US National Health and Nutrition Examination Survey (NHANES) indicated approximately 3.6 million noninstitutionalized persons with antibody to HCV (anti-HCV). However, state-level prevalence remains less understood and cannot be estimated reliably from NHANES alone. Methods.: We used 3 publicly available government data sources to estimate anti-HCV prevalence in each US state among noninstitutionalized persons aged ≥18 years...

OBJECTIVE: Chronic inflammation is linked to many chronic conditions. One of the strongest modulators of chronic inflammation is diet. The Dietary Inflammatory Index (DII) measures dietary inflammatory potential and has been validated previously, but not among African Americans (AAs). DESIGN: Cross-sectional analysis using baseline data from the Healthy Eating and Active Living in the Spirit (HEALS) intervention study. SETTING: Baseline data collection occurred between 2009 and 2012 in or near Columbia, SC...

Understanding how populations adapt to heterogeneous thermal regimes is essential for comprehending how latitudinal gradients in species diversification are formed, and how taxa will respond to ongoing climate change. Adaptation can occur by innate genetic factors, by phenotypic plasticity, or by a combination of both mechanisms. Yet, the relative contribution of such mechanisms to large-scale latitudinal gradients of thermal tolerance across conspecific populations remains unclear. We examine thermal performance in 11 populations of the intertidal copepod Tigriopus californicus, ranging from Baja California Sur (Mexico) to British Columbia (Canada)...

Cédric Aria, Jean-Bernard Caron
Retracing the evolutionary history of arthropods has been one of the greatest challenges in biology. During the past decade, phylogenetic analyses of morphological and molecular data have coalesced towards the conclusion that Mandibulata, the most diverse and abundant group of animals, is a distinct clade from Chelicerata, in that its members possess post-oral head appendages specialized for food processing, notably the mandible. The origin of the mandibulate body plan, however, which encompasses myriapods, crustaceans and hexapods, has remained poorly documented...

BACKGROUND: Monthly injections of palivizumab during the respiratory syncytial virus (RSV) season in at-risk infants reduces RSV-associated hospitalizations. However, the additive effect of naturally acquired immunity remains unclear. The objective of this study was to assess total neutralizing serum antibodies (NAb) against RSV in at-risk infants who had received an abbreviated course of palivizumab prophylaxis. METHODS: Serum samples were collected from infants enrolled in the RSV Immunoprophylaxis Program in British Columbia, Canada over 2 consecutive RSV seasons (2013 to 2015)...

Leon Gortler, Stephen J Weininger
The Hickrill Chemical Research Foundation, located north of New York City on the estate of its patrons, Sylvan and Ruth Alice Norman Weil, had a short (1948-59) but productive life. Ruth Alice Weil received a Ph.D. in organic chemistry in 1947, directed by William von Eggers Doering of Columbia University. She intended that Hickrill contribute to cancer chemotherapy while providing resources for Doering's more speculative research. Ultimately, Doering's commitment to theoretical organic chemistry set Hickrill's research agenda...

BACKGROUND: Benzodiazepines and benzodiazepine-like sedatives (zopiclone, zolpidem and zaleplon) are commonly prescribed to treat anxiety and insomnia but are contraindicated for chronic use. We sought to study the persistence, over multiple years, of chronic use of benzodiazepines and benzodiazepine-like sedatives among community-dwelling adults in British Columbia, Canada. METHODS: This is a retrospective analysis of linked health data for adults aged 50 to 69 in 2004 who resided in British Columbia, Canada, between 2004 and 2013...

BACKGROUND: Degenerative processes in neurodegenerative diseases can start years before clinical manifestation. We aimed to establish whether a multiple sclerosis prodromal period exists by examining patterns of health-care use before a first demyelinating event. METHODS: In this matched cohort study, we used data from linked health administrative and clinical databases from four Canadian provinces (British Columbia, Saskatchewan, Manitoba, and Nova Scotia) to compare hospital, physician, and prescription use data from people with multiple sclerosis and matched general population controls in the 5 years before the first demyelinating disease claim (health administrative index date) or clinically reported symptom onset (clinical index date)...

This study examines spatially variable stand structure and fire-climate relationships at a low elevation forest-grassland ecotone in west central British Columbia, Canada. Fire history reconstructions were based on samples from 92 fire-scarred trees and stand demography from 27 plots collected over an area of about 7 km(2) . We documented historical chronologies of widespread fires and localized grassland fires between AD 1600 and 1900. Relationships between fire events, reconstructed values of the Palmer Drought Severity Index and annual precipitation were examined using superposed epoch and bivariate event analyses...

BACKGROUND: Clinician's emotional responses to patients have been recognized as potentially relating to treatment outcome, however they have received little attention in the literature on suicide risk. We examine the relationship between a novel targeted measure of clinicians' emotional responses to high-risk psychiatric inpatients and their short-term post-discharge suicide behavior. METHODS: First-year psychiatry residents' emotional responses to their patients were assessed anonymously with the novel self-report 'Therapist Response Questionnaire-Suicide Form' (TRQ-SF)...

Pseudopecoelus mccauleyi n. sp. (Opecoelidae: Opecoelinae) is described from the intestine of the bigfin eelpout, Lycodes cortezianus (Gilbert, 1890) (Perciformes: Zoarcidae), collected at 200-800 m depths in the Northeastern Pacific Ocean off Oregon and Vancouver Island, British Columbia. The new species is distinguished by possessing a unique combination of the following diagnostic characters: vitelline fields that extend to the posterior margin of the ventral sucker; a slender, tubular and sinuous seminal vesicle that extends some distance into the hindbody; an unspecialized, protuberant ventral sucker; a genital pore at pharynx level; lobed to deeply multilobed testes; a lobed ovary; and an egg size of 68-80 μm × 30-46 μm...

To examine state statutes banning powdered alcohol, we identified relevant statutes in all 50 states and the District of Columbia through a search (initial search March 2016; follow-up search November 2016) using the legal research database LexisNexis. To identify the laws, we used the following search terms: "concentrated alcohol," "crystalline alcohol," "granulated alcohol," "palcohol," and "powdered alcohol." As of November 2016, 31 states had statutory bans on powdered alcohol. Statutes in 22 states outline penalties for violating the state's ban on powdered alcohol...

Ashley C Bradford, W David Bradford
In the past twenty years, twenty-eight states and the District of Columbia have passed some form of medical marijuana law. Using quarterly data on all fee-for-service Medicaid prescriptions in the period 2007-14, we tested the association between those laws and the average number of prescriptions filled by Medicaid beneficiaries. We found that the use of prescription drugs in fee-for-service Medicaid was lower in states with medical marijuana laws than in states without such laws in five of the nine broad clinical areas we studied...

PREMISE OF THE STUDY: Diverse in modern ecosystems, mosses are dramatically underrepresented in the fossil record. Furthermore, most pre-Cenozoic mosses are known only from compression fossils, lacking detailed anatomical information. When preserved, anatomy vastly improves resolution in the systematic placement of fossils. Lower Cretaceous deposits at Apple Bay (Vancouver Island, British Columbia, Canada) contain a diverse anatomically preserved flora that includes numerous bryophytes, many of which have yet to be characterized...
