Jeremy Morris as a pioneer of behavioural epidemiology, social medicine and public health.

Seventy years ago, the Scottish epidemiologist Jeremy Morris published his seminal papers in exercise epidemiology, providing evidence of the positive relationship between physical activity levels and reduced mortality. Today, we may remember Morris's pivotal role in establishing physical activity as a key factor in preventive medicine and public health. The roots of the role of behavioural epidemiology in modern public health lay in Morris's research on the association of coronary heart disease with physical activity at work.

Nutrition in the Management of ADHD: A Review of Recent Research.

Purpose Of Review: Various nutrients and diet quality have been suggested to be involved in the pathophysiology of ADHD. The purpose of this review was to examine data from recent cohort studies and dietary interventions to determine whether nutrition may play a role in the management of ADHD.

Recent Findings: Preliminary evidence suggests that minerals might have beneficial effects on ADHD symptomatology.

Sport and physical exercise in sustainable mental health care of common mental disorders: Lessons from the COVID-19 pandemic.

The large-scale disruptions to physical activity during the coronavirus pandemic have been found to be a leading predictor of common mental disorders. In addition, regular physical exercise has been found to alleviate anxiety, sadness and depression during the pandemic. These findings, together with numerous studies published before the pandemic on the effects of physical activity on mental health, should be considered in the provision of mental health care following the pandemic.

Effect of classroom-based physical activity interventions on attention and on-task behavior in schoolchildren: A systematic review.

Physical activity in children is associated with several cognitive benefits. Since children and adolescents spend an increasing amount of time engaged in sedentary behavior both at school and in their free time, movement breaks during class hours, in which students are physically active, may be beneficial for effective learning. The aim of this systematic research is to provide an overview of prospective studies investigating the influence of classroom-based physical activity (CB-PA) interventions on attention and on-task behavior in school-aged children and adolescents aged between 4 and 18 years.

The role of loneliness in university students' pathological Internet use - a web survey study on the moderating effect of social web application use.

The present study investigated the role of social web application use in the association between loneliness and pathological Internet use. A sample of university students (n = 445) completed an online survey of their loneliness and Internet use, including an assessment of pathological Internet use level. Based on existing theory and empirical findings, loneliness was expected to be indirectly associated with pathological Internet use through social-compensatory Internet use motives.

The role of state feelings of loneliness in the situational regulation of social affiliative behavior: Exploring the regulatory relations within a multilevel framework.

Previous empirical evidence suggests that the engagement in social interactions across different everyday contexts occurs in a manner highly responsive to a person's social affiliation needs. As has been shown repeatedly, social engagement (as well as disengagement) can be predicted from earlier situational need states, implying that homeostatic principles underlie a person's social affiliative behaviors. However, little is known about the role of emotion in these regulative processes.

Coronavirus disease 2019 (COVID-19) and global mental health.

The mental health effects of the coronavirus disease 2019 (COVID-19) pandemic may shape population health for many years to come. Failure to address the mental health issues stemming from the pandemic is likely to prolong its impact. The COVID-19 pandemic has created a significant global challenge and, in lower-income countries, even a disruption of mental health services.

Lifestyle factors in the prevention of COVID-19.

Confinement to the home and psychological distress due to the coronavirus disease 2019 (COVID-19) pandemic may lead to harmful health behaviors, such as overeating, sedentary behavior with reduced physical activity, elevated alcohol and tobacco use and increased screen time causing impaired sleep. All of these behaviors are associated with non-communicable diseases and can interfere with immunity. While no foods, single nutrients or dietary supplements are capable of preventing infection with COVID-19, a balanced diet containing sufficient amounts of macronutrients and diverse micronutrients is a prerequisite of an optimally functioning immune system.

Food science and COVID-19.

Theories proposing a role of specific dietary components or food supplements in the prevention or treatment of COVID-19 have received extensive social media coverage. A multitude of scientific publications have also pointed to the importance of food and nutrition in combating the COVID-19 pandemic. The present perspective critically addresses the question of what food science can actually contribute in this context.

The effects of video racing games on risk-taking in consideration of the game experience.

In the present study, we attempted to investigate whether it is the game experience that underlies processes leading to increased risk-taking while playing video racing games (VRGs). The aim of the study was to examine the indirect effect of playing VRGs on risky driving behaviour through various dimensions of the game experience. Thus, we examined the subjective experience of participants playing various VRGs and questioned whether this influenced subsequent driving behaviour.

Simulated car driving and its association with cognitive abilities in patients with schizophrenia.

Objectives: Patients with schizophrenia commonly suffer from impairments in various aspects of cognition. These deficits were shown to have detrimental effects on daily life functioning and might also impair car driving. This study is the first to examine driving behaviour of patients with schizophrenia using an advanced driving simulator, and to explore the role of cognitive abilities of people with schizophrenia for driving.

Noncredible cognitive performance at clinical evaluation of adult ADHD: An embedded validity indicator in a visuospatial working memory test.

The assessment of performance validity is an essential part of the neuropsychological evaluation of adults with attention-deficit/hyperactivity disorder (ADHD). Most available tools, however, are inaccurate regarding the identification of noncredible performance. This study describes the development of a visuospatial working memory test, including a validity indicator for noncredible cognitive performance of adults with ADHD.

Resveratrol, pterostilbene, and dementia.

Resveratrol is a natural phytoestrogen with neuroprotective properties. Polyphenolic compounds including resveratrol exert in vitro antioxidant, anti-inflammatory, and antiamyloid effects. Resveratrol and its derivative pterostilbene are able to cross the blood-brain barrier and to influence brain activity.

Patients' experience of breast reconstruction after mastectomy and its influence on postoperative satisfaction.

Purpose: Breast cancer patients have the option to choose a breast reconstruction after mastectomy. A range of studies have postulated that patients' individually appraised significance of their breast is an important factor in the decision for or against breast reconstruction. This study explored the individually perceived significance of the breast among patients with and without breast reconstruction and its correlation with postoperative satisfaction.

Dietary factors in the etiology and therapy of attention deficit/hyperactivity disorder.

Purpose Of Review: The purpose of this study is to discuss the role of dietary factors in the etiology and therapy of attention deficit/hyperactivity disorder (ADHD). Relevant literature published from January 2016 to January 2017 was included in this review.

Recent Findings: Unhealthy prenatal diet may be associated with ADHD in the offspring through an increase in epigenetic changes.

Effects of atomoxetine on attention in Wistar rats treated with the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4).

The aim of the present study was to assess the effects of the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4), which allows a depletion of noradrenergic terminals in a dose-dependent manner, on attention in rats as measured using the five-choice serial-reaction time task (5CSRTT). In addition, we investigated whether the effects of DSP4 treatment can be reversed by atomoxetine. Atomoxetine is a selective noradrenaline reuptake inhibitor and has been shown to be effective in the treatment of attention deficit hyperactivity disorder.

The Role of Nutritional Supplements in the Treatment of ADHD: What the Evidence Says.

Attention-deficit hyperactivity disorder (ADHD) is a common behavioral disorder in children and adolescents and may persist into adulthood. Insufficient nutritional supply of long-chain polyunsaturated fatty acids (LC-PUFAs) and other components including various minerals has been suggested to play a role in the development of ADHD symptoms. This review presents the evidence regarding the role of nutritional PUFA, zinc, iron, and magnesium supplements in the treatment of ADHD with a focus on the critical evaluation of the relevant literature published from 2014 to April 2016.

Effects of methylphenidate on attention in Wistar rats treated with the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4).

The aim of this study was to assess the effects of the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4) on attention in rats as measured using the 5-choice-serial-reaction-time task (5CSRTT) and to investigate whether methylphenidate has effects on DSP4-treated rats. Methylphenidate is a noradrenaline and dopamine reuptake inhibitor and commonly used in the pharmacological treatment of individuals with attention deficit/hyperactivity disorder (ADHD). Wistar rats were trained in the 5CSRTT and treated with one of three doses of DSP4 or saline.

The Development of an Embedded Figures Test for the Detection of Feigned Attention Deficit Hyperactivity Disorder in Adulthood.

Objectives: It has been shown that an increasing number of adults deliberately feign attention deficit hyperactivity disorder (ADHD), which demonstrates the need for new tests designed to detect feigned ADHD.

Methods: An Embedded Figures Test (EFT) was developed for the detection of feigned ADHD in adulthood. EFT performance of 51 adults with ADHD was compared to the performance of 52 matched healthy individuals, as well as to 268 undergraduate students who were randomly allocated in a simulation design to one of four experimental conditions, i.
