This study explored issues of culturally sensitive health care practice and needs among lesbian, gay, bisexual and transgender aging adults in coastal North Carolina. Survey data from 2013 to 2015 were analyzed using frequencies and logistic regression on concerns with culturally sensitive health needs for the LGBT aging adult population. Results indicated that the largest problem was a history of being verbally harassed (n = 115; 51.57%) and a need for more culturally sensitive health care provisions. A large majority of participants requested an improvement in offering of LGBT specific social activities (n = 149), recreational activities (n = 116), and art and cultural activities (n = 112)...

PURPOSE: The prevalence of traumatic brain injury (TBI) among offender populations is significantly higher than among the general population. Despite this, no study has yet assessed the knowledge of members of the probation service surrounding TBI. METHOD: Knowledge was assessed among members of the Probation Board for Northern Ireland (PBNI) using a cross-sectional online version of the Common Misconceptions about TBI (CM-TBI) questionnaire. Mean total misconception scores, along with scores on four subdomains (recovery, sequelae, insight, and hidden injury) were calculated...

Drive genes are genetic elements that manipulate the 50% ratio of Mendelian inheritance in their own favour, allowing them to rapidly propagate through populations. The action of drive genes is often hidden, making detection and identification inherently difficult. Yet drive genes can have profound evolutionary consequences for the populations that harbour them: most known drivers are detrimental to organismal gamete development, reproduction and survival. In this study, we identified the presence of a well-known drive gene called t haplotype post-hoc in eight replicate selection lines of house mice that had been evolving under enforced monandry or polyandry for 20 generations...

Allosteric effect implies ligand binding at one site leading to structural and/or dynamical changes at a distant site. PDZ domains are classic examples of dynamic allostery without conformational changes, where distal side-chain dynamics is modulated on ligand binding and the origin has been attributed to entropic effects. In this work, we unearth the energetic basis of the observed dynamic allostery in a PDZ3 domain protein using molecular dynamics simulations. We demonstrate that electrostatic interaction provides a highly sensitive yardstick to probe the allosteric modulation in contrast to the traditionally used structure-based parameters...

AIMS: To find out whether neuropsychiatric comorbidity (comMCI) influences spatial navigation performance in amnestic mild cognitive impairment (aMCI). METHODS: We recruited aMCI patients with (n = 21) and without (n = 21) neuropsychiatric comorbidity or alcohol abuse, matched for global cognitive impairment and cognitively healthy elderly participants (HE, n = 22). They completed the Mini-Mental State Examination and a virtual Hidden Goal Task in egocentric, allocentric, and delayed recall subtests...

Single-cell mRNA sequencing, which permits whole transcriptional profiling of individual cells, has been widely applied to study growth and development of tissues and tumors. Resolving cell cycle for such groups of cells is significant, but may not be adequately achieved by commonly used approaches. Here we develop a traveling salesman problem and hidden Markov model-based computational method named reCAT, to recover cell cycle along time for unsynchronized single-cell transcriptome data. We independently test reCAT for accuracy and reliability using several data sets...

Hidden populations, such as injecting drug users (IDUs), sex workers (SWs) and men who have sex with men (MSM), are considered at high risk of contracting and transmitting infectious diseases such as AIDS, gonorrhea, syphilis etc. However, public health interventions to such groups are prohibited due to strong privacy concerns and lack of global information, which is a necessity for traditional strategies such as targeted immunization and acquaintance immunization. In this study, we introduce an innovative intervention strategy to be used in combination with a sampling approach that is widely used for hidden populations, Respondent-driven Sampling (RDS)...

Respondent-driven sampling (RDS) is a link-tracing procedure used in epidemiological research on hidden or hard-to-reach populations in which subjects recruit others via their social network. Estimates from RDS studies may have poor statistical properties due to statistical dependence in sampled subjects' traits. Two distinct mechanisms account for dependence in an RDS study: homophily, the tendency for individuals to share social ties with others exhibiting similar characteristics, and preferential recruitment, in which recruiters do not recruit uniformly at random from their network alters...

In order to interact intelligently with objects in the world, animals must first transform neural population responses into estimates of the dynamic, unknown stimuli that caused them. The Bayesian solution to this problem is known as a Bayes filter, which applies Bayes' rule to combine population responses with the predictions of an internal model. The internal model of the Bayes filter is based on the true stimulus dynamics, and in this note, we present a method for training a theoretical neural circuit to approximately implement a Bayes filter when the stimulus dynamics are unknown...

Naonori Kodate, Virpi Timonen
In the era of global ageing, amid political concerns about increasing care needs and long-term sustainability of current care regimes, most high-income economies are seeking to minimise the use of institutional care and to expand formal home care for their older populations. In long-term care reforms, concerns about public funding, formal providers and the paid care workforce are foremost. However, an integral yet hidden part of all these reforms is the stealthily growing role of family carers. This article aims to identify and spell out how developments in formal home care bring about different modes of increasing, encouraging and necessitating family care inputs, across welfare states...

Efficacies of a handheld thermal fogger (Patriot™) and a backpack ultra-low volume (ULV) sprayer (Twister™) with combinations of 2 different adulticides (pyrethrin, deltamethrin) and an insect growth regulator (pyriproxyfen) were field-tested and compared for their impact on reducing indoor Aedes aegypti populations in Thailand. The effectiveness of the indoor space sprays was evaluated by sampling the natural Ae. aegypti population in houses and determining their physiological status, by monitoring mortality of sentinel caged mosquitoes (AFRIMS strain) and by assessing larval mortality in laboratory bioassays using water exposed to the spray...

Intestinal helminthiases affect millions of people worldwide, mainly in developing regions, where they cause a significant negative impact on human health and socioeconomic growth of affected populations. However, intestinal helminthiases are still among the most neglected tropical diseases. Protective immunity against intestinal helminths is associated with development of type 2 responses. Nevertheless, in some host-intestinal helminth combinations, local Th1 responses are initiated, inducing chronicity. The usage of helminth-mouse models is useful for elucidating the mechanisms behind the initiation of each type of response...

BACKGROUND: Preconception carrier screening for cystic fibrosis (CF) is usually performed using ethnically targeted panels of selected mutations. This has been recently challenged by the use of expanded, ethnically indifferent, pan-population panels. Israel is characterized by genetically heterogeneous populations carrying a wide range of CFTR mutations. To assess the potential of expanding the current Israeli preconception screening program, we sought the subset of molecularly unresolved CF patients listed in the Israeli CF data registry comprising ~650 patients...

BACKGROUND: Mucosal melanomas are rare and highly aggressive tumors. Few studies evaluated mucosal melanomas of locations other than the head and neck region, and other than those of the Asian population. OBJECTIVES: The objective of this study was to analyze the clinical and histological features, as well as the mutational status of c-kit and b-raf gene of mucosal melanoma in any localization in a French series. METHODS: We investigated clinical (sex, age, performance status, survival, treatment of the patients and lack of pigmentation of the tumors) and histopathologic features (ulceration, Breslow's index, mitotic rate), as well as the mutational status of c-kit and b-raf of 86 mucosal melanomas diagnosed in 15 years in four French University Hospitals...

Justice-involved HIV-positive women, particularly those in the U.S. South, are a hidden, understudied population. Little work has explored their psychosocial histories in relation to their HIV risk. We conducted a content analysis of their life history narratives from childhood to present, via in-depth interviews with 24 such women in 2 Alabama cities. Findings included the following: (a) In childhood/adolescence, consistent HIV risk factors were present, beginning with early sexual abuse and induction into alcohol/substance use; (b) By early adulthood, HIV and incarceration risks were compounded in social settings, through cyclical substance use, revictimization, and reoffending;...

BACKGROUND: Lysosomal acid lipase deficiency (LALD) is an autosomal recessive disorder and an unrecognized cause of dyslipidemia. Patients usually present with dyslipidemia and altered liver function and mutations in LIPA gene are the underlying cause of LALD. OBJECTIVE: The aim of this study was to investigate LALD in individuals with severe dyslipidemia and/or liver steatosis. METHODS: Coding, splice regions, and promoter region of LIPA were sequenced by Sanger sequencing in a cohort of mutation-negative familial hypercholesterolemia (FH) patients (n = 492) and in a population sample comprising individuals with several types of dyslipidemia and/or liver steatosis (n = 258)...

Introduction: Chronic kidney disease (CKD) includes a wide range of pathophysiological processes which will be observed along with abnormal function of kidneys and progressive decrease in glomerular filtration rate (GFR). According to the definition decreasing GFR must have been present for at least three months. CKD will eventually result in end-stage kidney disease. In this process different factors play role and finding the relations between effective parameters in this regard can help to prevent or slow progression of this disease...

BACKGROUND: Network Scale-up (NSU) method is an indirect method for the estimation of hidden behaviors. In NSU, respondents are asked about the number of members they know from a subpopulation of interest (e.g., injecting drug user) and assume that the prevalence of risky behavior in the networks of a random sample of respondents is similar to that of the population. However, first, we need to identify the total number of people each respondent knows [the social network size (C)]; Moreover, certain risky behaviors happen in particular age and gender groups...
