CLEAN VERSION ABSTRACT Background: Hospitalization presents a window of opportunity to treat smoking, and hospital-initiated smoking treatment has demonstrated effectiveness. Despite effective interventions, not all smokers will discontinue use, highlighting the need to better understand which patients achieve cessation. Traditional regression methods may not capture the complexity of inpatient smoker subgroups. METHODS: We conducted latent class analysis (LCA) with data from 397 hospitalized adult cigarette smokers enrolled in a randomized trial...

OBJECTIVES: Benefit finding, which refers to perceiving positive life changes resulting from adversity, has been associated with better psychosocial well-being in different chronic illnesses. However, little research to date has examined how benefit finding develops in the context of Type 1 diabetes (T1D). The present study aimed to identify trajectories of benefit finding across adolescence and to investigate prospective associations with depressive symptoms, self-care, and metabolic control...

We evaluate the potential for using high-risk human papillomavirus (hr-HPV) testing-based screening for cervical intraepithelial neoplasia (CIN) in routine health services in Thailand; its accuracy in comparison to that of conventional cytology (CC); and the utility of HPV16/18 positive results and liquid-based cytology (LBC) triage for HPV-positive women in the detection of high-grade CIN. Women aged 30-60 years in Ubon Ratchathani province, Thailand were screened with CC and hr-HPV testing and those abnormal on either tests were referred for colposcopy and/or directed biopsies...

BACKGROUND: This study estimated latent classes (i.e., unobserved subgroups in a population) of people who use drugs in Vancouver, Canada and examined how these classes relate to phylogenetic clustering of hepatitis C virus (HCV) infection. METHODS: HCV antibody positive people who use drugs from two cohorts in Vancouver, Canada (1996-2012) with a Core-E2 sequence were included. Time-stamped phylogenetic trees were inferred and phylogenetic clustering was determined by time to most common recent ancestor...

CONTEXT: While physical function is an important patient outcome, little is known about changes in physical function in older adults receiving chemotherapy (CTX). OBJECTIVES: Identify subgroups of older patients based on changes in their level of physical function; determine which demographic and clinical characteristics were associated with subgroup membership; and determine if these subgroups differed on quality of life (QOL) outcomes. METHODS: Latent profile analysis (LPA) was used to identify groups of older oncology patients (n=363) with distinct physical function profiles...

BACKGROUND: Persons with mild intellectual disability or borderline intellectual functioning are often studied as a single group with similar characteristics. However, there are indications that differences exist within this population. Therefore, the aim of this study was to identify classes of persons with mild intellectual disability or borderline intellectual functioning and to examine whether these classes are related to individual and/or environmental characteristics. METHODS: Latent class analysis was performed using file data of 250 eligible participants with a mean age of 26...

Uneven ripening in Vitis vinifera is increasingly recognized as a phenomenon of interest, with substantial implications for fruit and wine composition and quality. This study sought to determine whether variation late in ripening (∼Modified Eichhorn-Lorenz stage 39) was associated with developmental differences that were observable as fruits within a cluster initiated ripening (véraison). Four developmentally distinct ripening classes of berries were tagged at cluster véraison, sampled at three times late in ripening, and subjected to untargeted HPLC-MS to measure variation in amino acids, sugars, organic acids, and phenolic metabolites in skin, pulp, and seed tissues separately...

BACKGROUND: Sound evidence has linked the experience of adversity with depression. Less is known about this association over time. AIM: The aim of this study is to determine whether or not social adversity experienced by pregnant women is associated with their patterns of depressive symptoms over their reproductive life course. METHODS: Data were obtained from a cohort of women collected at their first obstetrical clinic visit of an index pregnancy (time-point 1) and at a further six time-points to 27 years following the birth...

This study examined (a) transition patterns from adolescent-specific depressive symptom trajectory classes to young adult-specific trajectory classes (N = 537; 15-26 years) and (b) identified risk factors associated with these transition patterns. The latent classes and transition analyses identified three transitional patterns of depressive symptom trajectories, including a deteriorating pattern (8.2%), a recovering pattern (22.5%), and a consistently low pattern (69.3%). Additionally, the results showed that contextual risk factors (i...

The menopause transition is characterized by significant hormonal changes that may predispose women to psychosocial maladjustment. Prospective studies to date have focused primarily on negative mood states and show equivocal findings. The primary goal of this study was to identify patterns of change with respect to positive and negative mood states (vigor, depression, tension, and stress) over a 5-year period in a cohort of women undergoing the transition to menopause. A secondary aim was to determine whether the identified trajectories were associated with menopause status as well as baseline health-related and psychological characteristics...

A potentially important but understudied aspect of prisoner reentry is the neighborhood environments experienced by formerly incarcerated people. We know that many formerly incarcerated people return to very disadvantaged neighborhood environments and that returning to disadvantaged neighborhoods after prison increases the risk of recidivism and reduces employment. Yet very little is known about the social, economic, and institutional processes that sort formerly incarcerated people into different neighborhoods after release or their trajectories of neighborhood attainment over time...

BACKGROUND: Crude single-item consumption metrics, such as "binge drinking" measures, mask the complexity and heterogeneity in young people's drinking; thus limiting our understanding of young people's drinking patterns as well as how alcohol drinking is associated with violent outcomes. OBJECTIVES: The current study employed a range of consumption and contextual indicators to explore heterogeneity in young people's (16-29 years) drinking practices, giving due consideration to their social nature...

INTRODUCTION: The Kato-Katz technique is the standard diagnostic test for Schistosoma mansoni infection in rural areas. However, the utility of this method is severely limited by the day-to-day variability in host egg excretion in the stool. In high-transmission areas, the point-of-care circulating cathodic antigen (POC-CCA) urine assay has proven to be a reliable test. However, investigations of the reliability of the POC-CCA assay in low-transmission regions are under way. This study aimed to evaluate the sensitivity and specificity of the POC-CCA assay and the morbidity of schistosomiasis in a low-endemic area in Brazil...

OBJECTIVES: Postpartum psychosis (PP) is known for its clear onset but its phenotype has never been clearly described in a cohort. The aim of this study was to describe PP symptomatology, and to identify subgroups of patients based on symptom profiles. METHODS: We prospectively assessed a wide range of symptoms in cases of PP in a cohort of women (N=130) admitted to the Mother-Baby inpatient unit. Using a person-centered analytic approach, we distinguished mutually exclusive subgroups of women...

Non-medical drug injection is a major risk factor for HIV infection in Russia and Estonia. Multiple drug use (polydrug) has further been associated with increased harms. We compared HIV, injecting and sexual risk associated with polydrug use among people who injected drugs (PWID) in 2012-2013 in Kohtla-Järve (Estonia, n = 591) and St Petersburg (Russia, n = 811). Using latent class analysis, we identified five (poly)drug classes, the largest consisting of single-drug injectors among whom an opioid was the sole drug injected (56% of PWID)...

Host CD8 T cell response to viral infections involves recognition of 8-10-mer peptides presented by MHC-I molecules. However, proteasomes generate predominantly 2-7-mer peptides, but the role of these peptides is largely unknown. Here, we show that single short peptides of <8-mer from Latent Membrane Protein 2 (LMP2) of Epstein Barr Virus (EBV) can bind HLA-A*11:01 and stimulate CD8(+) cells. Surprisingly, two peptide fragments between 4-7-mer derived from LMP2(340-349) were able to complement each other, forming combination epitopes that can stimulate specific CD8(+) T cell responses...

Research on healthy behaviour such as physical activity and healthy nutrition and their combination is lacking among university students in Arab countries. The current survey assessed healthy nutrition, and moderate/vigorous physical activity (PA) of 6266 students in Egypt, Libya, and Palestine. We computed a nutrition guideline achievement index using WHO recommendation, as well as the achievement of PA recommendations using guidelines for adults of the American Heart Association guidelines. Latent class regression analysis identified homogenous groups of male and female students, based on their achievements of both guidelines...
