We examined visit attendance patterns of mothers enrolled in the Nurse-Family Partnership (NFP) home visitation program and associations between these patterns and characteristics of the families and sites, with the goal of increasing participant engagement. We utilized repeated measures latent class analysis to identify attendance patterns among 66,967 mothers in NFP sites across the USA. Mothers enrolled from 1996 to 2010. Data were collected by home visitors and aggregated by the NFP National Service Office...

Objective: To determine whether physician preferences for end-of-life care were associated with variation in health care spending. Method: We studied 737 physicians who completed the life-sustaining treatment questionnaire in 1999 and were linked to end-of-life care data for the years 1999 to 2009 from Medicare-eligible beneficiaries from the Dartmouth Atlas of Health Care (in hospital-related regions [HRRs]). Using latent class analysis to group physician preferences for end-of-life treatment into most, intermediate, and least aggressive categories, we examined how physician preferences were associated with health care spending over a 7-year period...

OBJECTIVE: To examine 5-year trajectories of psychiatrist-treated late-life major depressive disorder (MDD), and evaluate whether previous vascular pathology is associated with more severe trajectories of late-life MDD. METHODS: Data were obtained from nationally representative civil, psychiatric, hospital, and prescription registers in Denmark. The sample included 11,092 older adults (≥60 years) who received their first diagnosis of MDD in a psychiatric facility in Denmark between 2000 and 2007...

BACKGROUND: While single psychosocial factors have been associated with cardiovascular outcomes, it is still unclear how they cluster. Therefore, we examined whether latent multidimensional psychosocial risk profiles could be identified in the European Society of Cardiology (ESC) psychosocial screening interview. Additionally we examined whether these profiles were associated with specific sociodemographic, clinical, and psychosocial characteristics. METHOD: 681 coronary artery disease patients (age=64...

BACKGROUND: Previous research suggests that sleep disorders are highly associated with other mental health problems. However, sleep problems even below the diagnostic threshold of sleep disorders are very common in the general population, which highly affects wellbeing and functioning. In order to broaden the focus beyond those severe cases we explored empirical patterns across the whole spectrum of sleep problems as well as associated clinical and other factors. METHOD: A representative community sample of N=1274 residents from the canton of Zurich was interviewed for sleep problems and diagnostic criteria for mental disorders as well as was given a number of mental health-related psychometrical checklists...

PURPOSE: Dissociation is a common symptom in Borderline Personality disorder (BPD) and its consideration is important for the therapeutic outcome. The aim of this cross-sectional study was to scrutinize the co-occurrence of BPD symptoms and dissociative experiences. In particular, we were interested in the occurrence of specific symptom clusters characterizing qualitatively different patient groups in a clinical sample of BPD patients. BASIC PROCEDURES: We analyzed the data of 103 patients in a specialized acute inpatient care crisis intervention unit...

Minjae Kim, Melanie M Wall, Guohua Li
BACKGROUND: Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality...

Pornography is widely accepted and used as an appropriate sexual practice. Previous literature has suggested that pornography users may be best viewed through a heterogenetic lens that indicates specific classes of pornography users. Furthering this previous research, a latent profile analysis was conducted using a sample of 635 college students (mean age men 20.22 (standard deviation [SD] = 3.10); women 19.16 [SD = 2.12]) over two time points to not only identify unique classifications of pornography users, but also examine specific sexual attitudes 3 months later of each classification...

Identity change is related to reductions in alcohol use among treatment seekers, but it is unclear the extent to which identity change is associated with reductions in alcohol use among nontreatment seeking hazardous drinkers. The goal of the current study was to examine whether change in problem drinker identity (i.e., self-reported identification as a problem or nonproblem drinker) was associated with reductions in heavy drinking among nontreatment seeking hazardous drinkers. Participants (n = 149) completed measures to assess alcohol use and were asked if they identified as a problem drinker at baseline and at 6-, 12-, 18-, and 24-month follow-ups...

Anand Pai, Leor S Weinberger
Current antivirals effectively target diverse viruses at various stages of their life cycles. Nevertheless, curative therapy has remained elusive for important pathogens, such as human immunodeficiency virus type 1 (HIV-1) and herpesviruses, in large part due to viral latency and the evolution of resistance to existing therapies. Here, we review the discovery of viral master circuits: virus-encoded autoregulatory gene networks that autonomously control viral expression programs (i.e., between active, latent, and abortive fates)...

End of life care may have elements of value that go beyond health. A generic measure of the benefits of end of life care could be helpful to decision makers. Such a measure, based on the capability approach, has recently been developed: the ICECAP Supportive Care Measure. This paper reports the first valuation exercise for that measure, with data from 6020 individuals collected from an on-line general population panel during June 2013. Individuals were asked to complete a stated choice experiment that combined best-worst scaling and a standard discrete choice experiment...

A major challenge for the development of an effective vaccine against tuberculosis (TB) is that the attributes of protective CD4(+) T cell responses are still elusive for human TB. Infection with HIV type 1 is a major risk factor for TB, and a better understanding of HIV-induced alterations of Mycobacterium tuberculosis-specific CD4(+) T cells that leads to failed host resistance may provide insight into protective T cell immunity to TB. A total of 86 participants from a TB-endemic setting, either HIV-infected or uninfected and with latent or active TB (aTB), were screened using M...

BACKGROUND: Heterogeneity in patients with low back pain is well recognised and different approaches to subgrouping have been proposed. One statistical technique that is increasingly being used is Latent Class Analysis as it performs subgrouping based on pattern recognition with high accuracy. Previously, we developed two novel suggestions for subgrouping patients with low back pain based on Latent Class Analysis of patient baseline characteristics (patient history and physical examination), which resulted in 7 subgroups when using a single-stage analysis, and 9 subgroups when using a two-stage approach...

Objectives The aim of this study consists in describing the nature of mental health comorbidity among workers. Precisely, we seek to examine the presence of concomitant associations between burnout (cynicism, emotional exhaustion, professionnal inefficacy) and psychoactive substance use (heavy episodic drinking, above low-risk drinking guidelines, and psychotropic drug use).Methods The SALVEO study is based on a cross-sectional sample of 1966 workers from the province of Québec, Canada. Latent class analyses were performed in order to identify typical patterns corresponding to distinct forms of mental health comorbidity in the data...

The role of cognitive mechanisms in the clinical course of neurodevelopmental disorders is poorly understood. Attention Deficit Hyperactivity Disorder (ADHD) is emblematic in that numerous alterations in cognitive development are apparent, yet how they relate to changes in symptom expression with age is unclear. To resolve the role of cognitive mechanisms in ADHD, a developmental perspective that takes into account expected within-group heterogeneity is needed. METHOD: The current study uses an accelerated longitudinal design and latent trajectory growth mixture models in a sample of children ages 7-13 years carefully characterized as with (n = 437) and without (n = 297) ADHD to (a) identify heterogeneous developmental trajectories for response inhibition, visual spatial working memory maintenance, and delayed reward discounting and (b) to assess the relationships between these cognitive trajectories and ADHD symptom change...

OBJECTIVE: Wives increasingly outearn their husbands, and gender relations theory suggests this arrangement may undermine men's well-being. We explore how long-term histories of spousal breadwinning may be associated with older men's self-rated mental and physical health, and risk of nine health diagnoses. METHOD: Using 30 years of couple-level income data from the Health and Retirement Study ( n = 1,095 couples), we use latent class analyses to identify six classes that differ with respect to the timing and level of wife breadwinning...

This study investigated potential heterogeneity in development among offspring (age 17) of teen mothers and maternal life course as correlates of variation. Using latent class analysis, subgroups of developmental outcomes were identified. Maternal standing in two life course realms (i.e., socioeconomic and domestic) was considered as a potential explanation for heterogeneity in offspring's development. Offspring reported on measures assessing their psychological, academic, and behavioral development. Teen mothers reported on measures of life course realms...

BACKGROUND: The objective was to evaluate the diagnostic accuracy of two serum ELISAs and one quantitative PCR on feces for the diagnosis of paratuberculosis in sub-clinically infected young-adult sheep. A cross-sectional study was performed to collect 1197 individual blood and fecal samples from 2- to 3-year-old sub-clinically infected ewes in 14 closed meat sheep flocks in France. Fecal excretion was determined using qPCR based on IS900 sequence detection, and serology was performed on serum samples using two commercial ELISAs...

Chronic widespread musculoskeletal pain (CWP) is a condition manifesting varied co-symptomatology and considerable heterogeneity in symptom profiles. This poses an obstacle for disease definition and effective treatment. Latent class analysis (LCA) provides an opportunity to find subtypes of cases in multivariate data. In this study, LCA was used to investigate whether and how individuals with CWP could be classified according to 12 additional somatic symptoms (migraine headaches, insomnia, stiffness, etc.)...
