The study evaluates the effectiveness of yoga practices on reducing stress, negative emotion, anxiety, and depression and on increasing positive emotion, wellbeing and resilience. The study uses randomized wait-list control. All U.S. undergraduate students in 4-year universities and colleges age 18 or older are eligible to participate.
The current study examines an adapted guided self-help stress reduction program, focusing on reducing stress in the time of COVID-19. Two studies are planned: 1) an international study in English in which individuals proficient in English throughout the world will participate and 2) a follow-up study in Hebrew.
The aim of the present project is to combine "Acceptance and Commitment Therapy" and "sleep hygiene + light-therapy (so-called chronotherapy)" serially in a sample of employees to reduce levels of subjective exhaustion.
The aim of this project is to test the effects of an environmental factor (mild stress) on prefrontal cortex (PFC) and the cognitive functions that depend on PFC (collectively called executive functions [EFs]), and to test our predictions concerning how those effects differ by biological factors (hormones and genotype). To test our hypotheses concerning mechanism, the investigators will model the effects of mild stress on EFs pharmacologically. The purpose is to pharmacologically model the effects of mild stress on the cognitive functions (collectively called "executive functions" [EFs]) dependent on the frontal lobe. The investigators would also like to investigate how gender differences and genotype mediate the effect of methylphenidate (MPH) on EFs.
Non-communicable diseases (NCDs) compose a substantial proportion of the global burden of diseases, posing a significant challenge in both high-income and low- and middle-income countries. In particular, certain lifestyle-related risk factors, such as unhealthy diet, physical inactivity, smoking, excessive alcohol consumption, and sleep deprivation are the leading risk factors, which place people at an increased risk of developing NCDs. On the other hand, a growing phenomenon of excessive concern about diet and health is emerging, and it is contributing to the development of a novel eating behavior disorder named orthorexia nervosa. According to recent studies, orthorexic behavior is very common among young adults and especially so in health-care professionals. The main objective of this multi-center study is to explore and compare lifestyle habits among undergraduate medical students and other healthcare-related professions from different countries (Croatia, Lebanon, Italy, Poland, Spain, and Turkey). The goal is to obtain information on the presence of unhealthy habits in order to be able to intervene, offering the information needed for primordial disease prevention in this young and still healthy group of respondents, who are the health educators and role models of the future. The particular importance of this goal is to raise awareness of the problem of the ubiquitously present unhealthy lifestyles. Unfortunately, health-care students are not the exception regarding the prevalence of the unhealthy diet, sedentary behavior, sleep deprivation and high levels of psychological stress. Furthermore, the adoption of unhealthy lifestyle patterns in health-care workers, such as doctors and nurses, will have far-reaching negative consequences, in both their health and their patients' health. The results of this study will be used for identifying the needs and targets for intervention, enabling students to become a pillar of health education for their patients and the population in general.
BACKGROUND: Musculoskeletal disorders, and in particular low-back pain (LBP), are common among blue collar workers. In the work environment, both physical- and psychosocial risk factors exist. Working in warehouses in Denmark involve large quantities of occupational lifting, high work pace and a low degree of influence at work. This study investigates both acute and long-term associations between physical- and psychosocial work environmental factors and risk of LBP in warehouse workers. The specific study aims are to investigate 1) exposure-response associations between quantity of occupational lifting and short-term (day-to-day) changes in LBP, 2) the influence of accumulated workdays and rest days during a working week on LBP, 3) long-term association between occupational lifting exposure and LBP when assessed over 1 year, and 4) the role of psychological and social factors on the above associations. METHODS: The present study is designed as a 1-year prospective cohort study that will examine full-time warehouse workers from up to five retail chains in Denmark. Study aims 1 and 2 will be addressed using objective data based on company records with information on weight of all the goods handled by each warehouse worker during every single workday for 3 weeks. During this period, each worker will reply to text messages received before and after every workday (also on days off work) in which study participants will score their pain in the low back, bodily fatigue and perceived mental stress (scale 0-10). Long-term pain development is assessed using questionnaire surveys before and after 1 year. Further, pressure pain threshold (PPT) will be measured for selected trunk extensor muscles in approximately 50 workers using algometry along with measurements of maximal trunk extensor strength. Associations are modelled using linear mixed models with repeated measures between variables and LBP controlled for relevant confounders. DISCUSSION: This study provides knowledge about the acute and long-term associations between physical- and psychosocial work environmental factors and LBP. The obtained data will have the potential to provide recommendations on improved design of the working week to minimize the risk of LBP among warehouse workers, and may potentially enable to identify a reasonable maximum lifting threshold per day (ton lifted/day).
This study is investigating whether acute administration of citalopram is associated with a decrease in stress reactivity in healthy volunteers, compared to placebo administration. Using a parallel-group double-blind design, participants will be randomised to receive either an acute dose of citalopram or placebo. All participants will have come in for a screening visit. On the day of the research visit (following drug administration) participants will have completed a number of widely used computer-based cognitive tasks measuring emotional processing biases. They will then complete the Oxford Cognition Stress Task, a web-based acute stress induction paradigm, which is designed to induce mild transient increases in stress and arousal. Identifying early changes in stress reactivity following antidepressant treatment will increase the investigator's knowledge of how antidepressants operate, and provide putative targets to identify early response to antidepressants.
The aim of the study is to determine whether premedication with midazolam before oocyte aspiration in IVF procedures affects the amount of (oxidative) stress in women undergoing IVF and whether stress is also transmitted to the follicular fluid of aspirated follicles. The primary endpoint is the impact of stress during aspiration on the success of medically assisted fertilization (IVF / ICSI in the stimulated cycle).
