Acute stress reactivity and intrusive memory development : a randomized trial using an adjusted trauma film paradigm

Understanding the neurobiological and cognitive processes underlying the development of posttraumatic stress disorder (PTSD) and its specific symptoms may facilitate preventive intervention development. Severe traumatic stress and resulting biological stress system activations can alter contextual memory processes. This may provide a neurobiological explanation for the occurrence of intrusive memories following trauma.

The course of symptoms in the first 27 months following bereavement : A latent trajectory analysis of prolonged grief, posttraumatic stress, and depression

Background

Much remains unknown about the course of grief in the early months following bereavement, including the prevalence and timing of a recovery trajectory, whether specific symptoms mark a failure to recover, and the co-occurrence of chronic prolonged grief (PG), posttraumatic stress (PTS) and depression symptoms.

Methods

The impact of neighborhood context on telomere length : A systematic review

A growing body of research demonstrates the association between neighborhood context and health. The underlying biological mechanisms of this association are not fully understood. We conducted a systematic review of studies that investigated the association between neighborhood context and telomere length (TL), a DNA-protein complex that shortens after cell division. Short TL is linked to age-related diseases and may be impacted by chronic stress. Nineteen eligible articles identified through PubMed and Scopus met inclusion criteria.

Differences in mental health problems, coping self-efficacy and social support between adults victimised before and adults victimised after the COVID-19 outbreak : population-based prospective study

Background Victims of violence, accidents and threats are at risk for mental health problems. Lower coping self-efficacy and social support levels increase this risk. Although highly relevant, it is unknown if the coronavirus disease 2019 (COVID-19) pandemic amplifies these risks.

 

Neurobiological mechanisms underlying delayed expression of posttraumatic stress disorder : A scoping review

BACKGROUND
The capacity of posttraumatic stress disorder (PTSD) to occur with delayed onset has been documented in several systematic reviews and meta-analyses. Neurobiological models of PTSD may provide insight into the mechanisms underlying the progressive increase in PTSD symptoms over time as well as into occasional occurrences of long-delayed PTSD with few prodromal symptoms. 

 

AIM
To obtain an overview of key concepts explaining and types of evidence supporting neurobiological underpinnings of delayed PTSD. 

 

Changes in social functioning over the course of psychotic disorders – A meta-analysis

In this meta-analysis we investigated changes in social functioning and its moderators in patients with a psychotic disorder but different durations of illness at baseline.

 

Course and predictors of posttraumatic stress and depression longitudinal symptom profiles in refugees : A latent transition model

Exposure to potentially traumatic events and post-migration living difficulties (PMLDs) may explain the high rates of posttraumatic stress disorder (PTSD) and depression in resettled refugees. Latent class analyses (LCAs) in refugees have identified subgroups that differ in symptom profiles of PTSD and comorbid symptoms. However, knowledge on longitudinal symptom profiles in refugees is sparse. Examining longitudinal PTSD and depression symptom profiles could provide information on risk factors underlying worsening of symptoms post-resettlement.

A systematic review of loneliness in bereavement : Current research and future directions

Bereaved people suffer from loneliness and loneliness is associated with poor mental health. In this study, this topic is reviewed. An agenda is suggested for future research. Research that is theory-driven, addresses measurement consistency, correlates of loneliness in bereaved and non-bereaved, and treatment is necessary for prevention and intervention.
