There is conflicting evidence about whether living with pets results in better mental and physical health outcomes, with the majority of the empirical research evidence being inconclusive due to methodological limitations. We briefly review the research evidence, including the hypothesized mechanisms through which pet ownership may influence health outcomes. This study examines how pet and non-pet owners differ across a variety of socio-demographic and health measures, which has implications for the proper interpretation of a large number of correlational studies that attempt to draw causal attributions...

During bone remodelling, osteoclasts induce chemotaxis of osteoblasts and yet maintain spatial segregation. We show that osteoclasts express the repulsive guidance factor Semaphorin 4D and induce contact inhibition of locomotion (CIL) in osteoblasts through its receptor Plexin-B1. To examine causality and elucidate how localized Plexin-B1 stimulation may spatiotemporally coordinate its downstream targets in guiding cell migration, we develop an optogenetic tool for Plexin-B1 designated optoPlexin. Precise optoPlexin activation at the leading edge of migrating osteoblasts readily induces local retraction and, unexpectedly, distal protrusions to steer cells away...

PURPOSE: To estimate the Australian cancer burden attributable to lifestyle-related risk factors and their combinations using a novel population attributable fraction (PAF) method that accounts for competing risk of death, risk factor interdependence and statistical uncertainty. PARTICIPANTS: 365 173 adults from seven Australian cohort studies. We linked pooled harmonised individual participant cohort data with population-based cancer and death registries to estimate exposure-cancer and exposure-death associations...

Studies generally show children who have entered out-of-home care have worse educational outcomes than the general population, although recent research suggests maltreatment and other adversities are major contributing factors. Children's out-of-home care experiences vary and may affect their outcomes. This study examined the influence of placement stability, reunification, type of care, time in care and age at entry to care on children's educational outcomes. We conducted a population-based record-linkage study of children born in Western Australia between 1990 and 2010 who sat State or national Year 3 reading achievement tests (N=235,045 children, including 2160 children with a history of out-of-home care)...

BACKGROUND: Rectal sexually transmitted infections (STI) have been associated with human immunodeficiency virus (HIV) diagnosis, but inferring a causal association requires disentangling them from receptive anal intercourse (RAI). METHODS: We conducted a stratified case-control study by frequency matching 4 controls to each case within year using clinical data from men who have sex with men (MSM) attending the Seattle STD Clinic 2001 to 2014. Cases were MSM with a new HIV diagnosis and negative HIV test at 12 months or less...

OBJECTIVE: In Northern Malawi, the duration of untreated psychosis (DUP) is longer than that in high-income countries. The reasons for the delay in help-seeking are not known, although studies show multiple reasons. This research was conducted to establish health care help-seeking behaviours and identify barriers that exist between service users and health care providers. The study also intended to establish the beliefs that clients and family members have regarding the causes of mental illness which profoundly shape help-seeking, care giving process and outcomes...

OBJECTIVES: Evidence of impairment in explicit mentalizing in people with schizophrenia has inspired interventions to improve awareness of others' mental states in these individuals. Less is known of implicit mentalizing in schizophrenia, with current findings mixed. We sought to resolve previous inconsistencies using Heider & Simmel's (H&S) classic animation to elicit spontaneous mentalizing and examined relations between spontaneous and deliberative mentalizing. METHODS: Forty-five schizophrenia outpatients and 27 general-community controls completed two explicit theory-of-mind (TOM) tasks and then described the H&S animation (to elicit spontaneous social attributions about emotionally driven, as well as goal-driven, behaviours), before and after an instruction to think of the shapes as people...

In the histopathological particle algorithm polyethylene (PE) particles with maximum lengths of more than 100μm - called PE supramacroparticles - are identified exclusively for knee joint and hip prostheses. However, a definitive characterisation, detection in all joint localisations and a causal clarification of the pathogenesis are lacking. In this study a total of 175 SLIM (synovial-like interface membrane) cases with PE supramacroparticles of knee joint prostheses (n=89), hip joint prostheses (n=44), ankle joint prostheses (n=36) and prostheses in three localisations of the upper extremities (n=6) were systematically investigated...

The compound BMAA (β-N-methylamino-L-alanine) has been postulated to play a significant role in four serious neurological human diseases: Amyotrophic Lateral Sclerosis/Parkinsonism Dementia Complex (ALS/PDC) found on Guam, and ALS, Parkinsonism, and dementia that occur globally. ALS/PDC with symptoms of all three diseases first came to the attention of the scientific community during and after World War II. It was initially associated with cycad flour used for food because BMAA is a product of symbiotic cycad root-dwelling cyanobacteria...

Traditionally, the self-serving bias has been investigated in ambiguous contexts in which participants work on tasks that measure novel abilities before making attributions without clear criteria for success or failure feedback. Prior studies have confirmed that the self-serving bias is pervasive in the general population, yet it varies significantly across situations involving ambiguous contexts. The present study features an unambiguous context encompassing interpersonal events that involved implicit causality (with the "self" as an actor or recipient), the inherent logic of which indicated attribution criteria...

BACKGROUND: Policy and environmental strategies are part of a comprehensive approach to obesity prevention. We investigated the association between public attitudes about how the environment influences health and support for a sugar-sweetened beverage (SSB) tax in Kansas. METHOD: We collected data via a 2014 representative dual-frame (cellular and landline) telephone survey of 2,203 adult Kansans regarding healthy eating policy support and beliefs about obesity causes and solutions...

Diabetes is a major cause of morbidity, disability, mortality and health care resource use. The increasing prevalence of diabetes may therefore have dramatic future consequences for western societies. Diabetes entails a significant self-management component and it has previously been estimated that people with diabetes provide about 95% of their own care. Despite increased focus, self-management skills including basic knowledge acquisition, problem solving and setting realistic goals are often not mastered...

Children with developmental delays (DD) are at risk for developing behavior problems. Research suggests that parents' causal attributions for child behavior are related to parenting. This study investigated this association in parents of children with DD compared to parents of typically developing (TD) children. It specifically focused on attributions of child control by separating these from attributions of responsibility, blame and intent, and from attributions of parent control and responsibility. Fifty-one parents of children with DD and 69 parents of TD children completed two questionnaires...

The Flint Water Crisis (FWC) is divisible into four phases of child water-lead exposure risk: Phase A) before the switch in water source to the Flint River (our baseline); Phase B) after the switch in water source, but before boil water advisories; Phase C) after boil water advisories, but before the switch back to the baseline water source of the Detroit Water and Sewerage Department (DWSD); and Phase D) after the switch back to DWSD. The objective of this work is to estimate water-lead attributable movements in child blood lead levels (BLLs) that correspond with the four phases in the FWC...

Objective Analysis of the development of psychiatric attitude research in Germany over the past 50 years. Methods Historical overview based on systematic reviews of population-based studies. Results In the beginning, public attitudes towards people with mental disorders and towards psychiatry were studied from a sociological perspective, later on research was guided by a social psychological or individual psychological approach. This provided important insights into processes underlying the stigma of mental illness (e...

Khat chewing is deeply rooted in the culture and tradition of communities in khat belt countries, and its consumption is spread to other countries through the suitcase trade. The aim of this article is to review current knowledge on the chemistry, social, pharmacology and toxicology of khat and its use. Khat produces effect invariably in every system, which is harmful or beneficial in some instances. Harmful effects are observed in heavy users, although firm evidence is lacking. Chewing khat acutely elicits states of euphoria, which is followed by low mood...

Stroke remains the most dangerous and frightening complication of atrial fibrillation (AF). Causal relationship between ischemic stroke and atrial arrhythmias such as AF or atrial flutter has been well established. Numerous factors predisposing to peripheral embolism in patients with AF have been well established and included in the CHA2DS2Vasc score. Although proper anticoagulation minimizes the risk attributable to "known" risk factors, stroke may still occur. Thus, "unknown" risk factors may play an important role in stroke risk stratification in patients with AF...

Background X-linked hypohidrotic ectodermal dysplasia (XLHED), the most common form of ectodermal dysplasia, is caused by mutations in the gene EDA. While only affected men develop the full-blown clinical picture, females who are heterozygous for an EDA mutation often also show symptoms such as hypodontia, hypotrichosis and hypohidrosis. These women may also suffer from malformations of the mammary gland which represent not just a cosmetic problem but can limit their breastfeeding capability. This paper summarizes the findings of the first systematic study on the impact of hypohidrotic ectodermal dysplasia on breastfeeding...

Lorraine Armstrong, Ashley Shepherd, Fiona Harris
BACKGROUND: Improving the quality of healthcare remains central to UK and international policy, practice and research. In 2003, The Institute of Medicine's 'Health Professions Education: A Bridge to Quality', advocated quality improvement as a core competency for all healthcare professionals. As a result, developing capacity and capability of those applying improvement methodologies in the pre-registration population has risen, yet, little is known about the teaching approaches employed for this purpose...

Self-efficacy has been associated with smoking cessation outcomes in many correlational research studies, but strong causal inferences are lacking. This study tested whether self-efficacy affects initial smoking cessation in a laboratory experiment, which will allow for stronger causal inferences in this domain of inquiry. Participants (n=103 motivated adult smokers) were provided with brief cessation treatment over three days in preparation for quitting on a target quit day (TQD). In addition, participants were randomized to one of two standard self-efficacy manipulations in the form of bogus feedback about their chances of quitting smoking...
