An energy-dense, high-fat, low-fibre dietary pattern has been prospectively associated with the development of obesity in childhood but is population-specific, which limits translating the pattern into interventions. We explored the generalisability and correlates of this obesogenic dietary pattern in the UK National Diet and Nutrition Survey (NDNS) for the first time. Data came from participants ( n = 4636 children and n = 4738 adults) with 4-day food diaries in NDNS 2008-2014. Reduced rank regression was applied to 51 food groups to explain variation in energy density, fibre and fat intake...

The goal of this cross-sectional qualitative study was to assess the impact of climate change on Sámi youth health, health care access, and health-seeking behaviour. Indigenous research methodology served as the basis of the investigation which utilised focus groups of youths and one-on-one interviews of adult community leaders using a semi-structured, open-ended questions. The results of the focus groups and interviews were then analysed to identify trends. We found that Sámi youth mostly associate the implications of climate change to their culture andcultural practices rather than the historical influence the environment had on Sámi health...

Social motivation is a subjective state which is rather difficult to quantify. It has sometimes been conceptualised as "behavioural effort" to seek social contact. Two paradigms: approach-avoidance (AA) and choose a movie (CAM), based on the same conceptualisation, have been used to measure social motivation in people with and without autism. However, in absence of a direct comparison, it is hard to know which of these paradigms has higher sensitivity in estimating preference for social over non-social stimuli...

Long-distance animal movements can increase exposure to diverse parasites, but can also reduce infection risk through escape from contaminated habitats or culling of infected individuals. These mechanisms have been demonstrated within and between populations in single-host/single-parasite interactions, but how long-distance movement behaviours shape parasite diversity and prevalence across host taxa is largely unknown. Using a comparative approach, we analyse the parasite communities of 93 migratory, nomadic and resident ungulate species...

Information is a crucial currency for living organisms as it allows them to adjust their behaviour to environmental fluctuations. Thus, natural selection should have favoured the capacity of collecting information from different sources, including social interactions whereby individuals could quickly gain reliable information. However, such conditions may also favour the gathering of potentially detrimental information, such as false or misinterpreted accounts of environmental and social phenomena such as rumours, which may spread via informational cascades...

An important way to resolve games of conflict (snowdrift, hawk-dove, chicken) involves adopting a convention: a correlated equilibrium that avoids any conflict between aggressive strategies. Dynamic networks allow individuals to resolve conflict via their network connections rather than changing their strategy. Exploring how behavioural strategies coevolve with social networks reveals new dynamics that can help explain the origins and robustness of conventions. Here, we model the emergence of conventions as correlated equilibria in dynamic networks...

BACKGROUND: Depression is the largest contributor to disease burden globally. The evidence favouring physical activity as a treatment for mild-to-moderate depression is extensive and relatively uncontested. It is unclear, however, how to increase an uptake of physical activity amongst individuals experiencing mild-to-moderate depression. This leaves professionals with no guidance on how to help people experiencing mild-to-moderate depression to take up physical activity. The purpose of this study was to scope the evidence on interventions to increase the uptake of physical activity amongst individuals experiencing mild-to-moderate depression, and to develop a model of the mechanisms by which they are hypothesised to work...

BACKGROUND: Complexity thinking is increasingly being embraced in healthcare, which is often described as a complex adaptive system (CAS). Applying CAS to healthcare as an explanatory model for understanding the nature of the system, and to stimulate changes and transformations within the system, is valuable. MAIN TEXT: A seminar series on systems and complexity thinking hosted at the University of Toronto in 2016 offered a number of insights on applications of CAS perspectives to healthcare that we explore here...

BACKGROUND: Efficient A(H5N1) control is unlikely to be based on epidemiological data alone. Such control depends on a thorough understanding and appreciation of the interconnectedness of epidemiological, social, and economic factors that contribute to A(H5N1) vulnerability. To date, the control of A(H5N1) in Egypt has been challenging. The disease has been endemic for more than 10 years with a dramatic increase in human cases between December 2014 and March 2015. Part of the problem has been a lack of understanding of the inter-play of drivers, conditions and motives that influence preventive behaviours at the household level...

Infanticide can be an extreme result of sexual conflict that drives selection in species in which it occurs. It is a rarely observed behaviour but some evidence for its occurrence in cetaceans exists in three species of dolphin. Here we describe observations of an adult male killer whale (Orcinus orca) and his post-reproductive mother killing a neonate belonging to an unrelated female from the same population in the North Pacific. This is the first account of infanticide reported in killer whales and the only case committed jointly by an adult male and his mother outside of humans...

Early life vitamin D plays a prominent role in neurodevelopment and subsequent brain function, including schizophrenic-like outcomes and increasing evidence for an association with autism spectrum disorder (ASD). Here, we investigate how early life vitamin D deficiency during rat pregnancy and lactation alters maternal care and influences neurodevelopment and affective, cognitive and social behaviours in male adult offspring. Sprague-Dawley rats were placed on either a vitamin D control (2195 IU/kg) or deficient diet (0 IU/kg) for five weeks before timed mating, and diet exposure was maintained until weaning of offspring on postnatal day (PND) 23...

Elevated levels of the type III (III) isoforms of neuregulin 1 (NRG1) have been observed in the brains of schizophrenia patients that carry NRG1 HapICE risk alleles, which is thought to contribute to the aetiology of the disease. We generated transgenic mice with forebrain driven Nrg1 III overexpression (Nrg1 III tg) and previously found that male heterozygous Nrg1 type III tg mice exhibit several schizophrenia-relevant behaviours including social and cognitive deficits as well as impaired sensorimotor gating...

Hans Heinze and the Research Programme of the German Association of Child Psychiatry and Therapeutic Education 1942-1945 Upon its foundation in 1940, Paul Schröder, full professor for psychiatry in Leipzig, was the first president of the German Society for Child Psychiatry and Therapeutic Education (DGKH). Following his death in 1941, his student Hans Heinze (Brandenburg/H.) succeeded him, prevailing over Werner Villinger (Breslau). The principal task of the DGKH was considered to be the exploration of the genetic origins of intellectual disabilities and behavioural disorders among children and adolescents...

PURPOSE: To investigate whether psychotic experiences and depressive symptoms at ages 12 and 18 years are associated with adverse life outcomes across a range of functional domains between 16 and 20 years of age. METHODS: Data were gathered from ALSPAC, a UK birth cohort. Individuals were assessed with the semi-structured Psychosis-Like Symptoms Interview and the Short Mood and Feeling Questionnaire at ages 12 and 18 years. Logistic regression was used to explore associations with outcomes in education, occupation, social functioning, substance use (alcohol, cannabis, smoking, and other drugs), and illegal behaviour between the ages of 16 and 20 years...

When complex systems are driven to depletion by some external factor, their non-stationary dynamics can present an intermittent behaviour between relative tranquility and burst of activity whose consequences are often catastrophic. To understand and ultimately be able to predict such dynamics, we propose an underlying mechanism based on sharp thresholds of a local generalized energy density that naturally leads to negative feedback. We find a transition from a continuous regime to an intermittent one, in which avalanches can be predicted despite the stochastic nature of the process...

BACKGROUND: Women at pre partum and post partum are especially susceptible to war trauma because they struggle to protect their infants from danger. Trauma research suggests increased problems in maternal mental health and infant development. Yet many cognitive-emotional processes affect the trauma survivors' mental health, such as post-traumatic growth and post-traumatic cognition. The aim of this study was to examine whether a mother's high post-traumatic growth and optimal post-traumatic cognition could protect their own mental health and their infant's stress regulation from the effects of traumatic war experiences...
