BACKGROUND: Tryptophan breakdown is an important mechanism in several diseases e.g. inflammation and stress-induced inflammation have been associated with the development of depression via enhanced tryptophan breakdown. Depression is a major public health problem which commonly starts during adolescence, thus identifying underlying mechanisms during early life is crucial in prevention. The aim of this work was to verify whether independent and interacting associations of psychosocial stress and inflammation on tryptophan breakdown already exist in children and adolescents as a vulnerable age group...

Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder typified by diagnostic symptom clusters including hyperarousal, avoidance, negative cognitions and mood, and intrusive re-experiencing of the traumatic event. Patients with PTSD have been reported to self-medicate with alcohol to ameliorate hyperarousal symptoms associated with the disorder. Research utilizing rodent models of PTSD to emulate this behavioral phenomenon has thus far yielded inconsistent results. In the present study, we examined the effects of a predator-based psychosocial stress model of PTSD on voluntary ethanol consumption...

Chronic social isolation causes severe psychological effects in humans, but their neural bases remain poorly understood. 2 weeks (but not 24 hr) of social isolation stress (SIS) caused multiple behavioral changes in mice and induced brain-wide upregulation of the neuropeptide tachykinin 2 (Tac2)/neurokinin B (NkB). Systemic administration of an Nk3R antagonist prevented virtually all of the behavioral effects of chronic SIS. Conversely, enhancing NkB expression and release phenocopied SIS in group-housed mice, promoting aggression and converting stimulus-locked defensive behaviors to persistent responses...

Adverse events in childhood and adolescence, such as social neglect or drug abuse, are known to lead to behavioral changes in young adulthood. This is particularly true for the subset of people who are intrinsically more vulnerable to stressful conditions. Yet the underlying mechanisms for such developmental trajectory from early life insult to aberrant adult behavior remains elusive. Adolescence is a period of dynamic physiological, psychological, and behavioral changes, encompassing a distinct neurodevelopmental stage called the 'critical period'...

A growing number of studies have shown that visiting green spaces and being exposed to natural environments can reduce psychological stress. A number of questions concerning the effects of natural environments on levels of stress remain including, "Are activities engaged in natural environments more or less beneficial at reducing stress when compared to those done in more urban settings?" This study examined this question from the perspective of "levels of nature". That is, data on levels of stress were collected from three sites, one site having wilderness-like characteristics, a second site representing a municipal-type park, and a third site representing a built environment (indoor exercise facility) within a city...

BACKGROUND: Intensive care patients experience poor sleep quality. Psychological distress and diminished health-related quality of life (HRQOL) are also common among former intensive care unit (ICU) patients. Coronary artery bypass graft (CABG) surgery is a frequent reason adults require treatment in ICU. The effect of on- versus off-pump surgery on sleep and recovery has not been reported. OBJECTIVE: The aim of this study was to assess sleep quality of CABG patients during and after ICU, psychological well-being, HRQOL during recovery, and whether on- versus off-pump surgery affects sleep and recovery...

The combination of mindfulness and self-hypnosis could provide a tool that is easily implemented by individuals who want to care for their well-being in times of high stress. Each discipline has been shown to be effective in relieving stress, and integration could further facilitate change while creating a tool that is highly accessible. There are many similarities between the two practices, such as focusing of attention and the emphasis on mind-body connection. However, important distinctions in psychological (e...

Mechanical ventilation in the intensive care unit requires the use of medication to reduce pain, discomfort, anxiety, and agitation. An explicit recall refers to the phenomenon where the person remembers the perceptions that occurred under sedation during mechanical ventilation. Severe psychological consequences may occur as a result of an explicit recall. This phenomenon is not well-defined and there is no common language in the literature. A conceptual analysis was carried out using Rodgers' evolutionary method in order to clarify the concept of explicit recall...

REVIEW
Joseph Maroon, Jeff Bost
Background: Numerous physical, psychological, and emotional benefits have been attributed to marijuana since its first reported use in 2,600 BC in a Chinese pharmacopoeia. The phytocannabinoids, cannabidiol (CBD), and delta-9-tetrahydrocannabinol (Δ9-THC) are the most studied extracts from cannabis sativa subspecies hemp and marijuana. CBD and Δ9-THC interact uniquely with the endocannabinoid system (ECS). Through direct and indirect actions, intrinsic endocannabinoids and plant-based phytocannabinoids modulate and influence a variety of physiological systems influenced by the ECS...

Latino day laborers are a socially and economically marginalized immigrant population with a high risk of occupational injury. These workers confront multiple social, psychological, and environmental hardships that increase their risk for adverse health outcomes. How these stressors interact and influence work-related injuries in this population remains unclear. We conducted an exploratory study with 327 Latino day laborers who completed a community survey. We developed a structural equation model, using cross-sectional data to explore the relationships among socioeconomic status, situational and immigration stress, depression, work risk exposure, and occupational injury...
