Effects of recurrent violence on post-traumatic stress disorder and severe distress in conflict-affected Timor-Leste: a 6-year longitudinal study.
Lancet Glob Health
PUBLISHED: 04-23-2014
Show Abstract
Hide Abstract
Little is known about the effect of recurrent episodes of communal violence on mental health in countries recovering from mass conflict. We report results of a 6-year longitudinal study in post-conflict Timor-Leste assessing changes in mental health after a period of communal violence.

Posttraumatic stress disorder and prolonged grief in refugees exposed to trauma and loss.
BMC Psychiatry
PUBLISHED: 03-31-2014
Show Abstract
Hide Abstract
While a large proportion of conflict-affected populations have been dually exposed to trauma and loss, there is inadequate research identifying differential symptom profiles related to bereavement and trauma exposure in these groups. The objective of this study were to (1) determine whether there are distinct classes of posttraumatic stress disorder (PTSD) and prolonged grief disorder (PGD) symptoms in bereaved trauma survivors exposed to conflict and persecution, and (2) examine whether particular types of refugee experiences and stressors differentially predict symptom profiles.

Patterns of risk for anxiety-depression amongst Vietnamese-immigrants: a comparison with source and host populations.
BMC Psychiatry
PUBLISHED: 11-19-2013
Show Abstract
Hide Abstract
Studies suggest that immigrants have higher rates of anxiety-depression than compatriots in low-middle income countries and lower rates than populations in host high income countries. Elucidating the factors that underlie these stepwise variations in prevalence may throw new light on the pathogenesis of anxiety-depressive disorders globally. This study aimed to examine whether quantitative differences in exposure to, or the interaction between, risk factors account for these anxiety-depression prevalence differences amongst immigrant relative to source and host country populations.

Achieving convergence between a community-based measure of explosive anger and a clinical interview for intermittent explosive disorder in Timor-Leste.
J Affect Disord
PUBLISHED: 06-06-2013
Show Abstract
Hide Abstract
There is growing research interest in understanding and analyzing explosive forms of anger. General epidemiological studies have focused on the DSM-IV category of Intermittent Explosive Disorder (IED), while refugee and post-conflict research have used culturally-based indices of explosive anger. The aim of this study was to test the convergence of a culturally-sensitive community measure of explosive anger with a structured clinical interview diagnosis of IED in Timor-Leste, a country with a history of significant mass violence and displacement.

Intermittent explosive disorder amongst women in conflict affected Timor-Leste: associations with human rights trauma, ongoing violence, poverty, and injustice.
PLoS ONE
PUBLISHED: 01-01-2013
Show Abstract
Hide Abstract
Women in conflict-affected countries are at risk of mental disorders such as posttraumatic stress disorder and depression. No studies have investigated the association between experiences of abuse and injustice and explosive anger amongst women in these settings, and the impact of anger on womens health, family relationships and ability to participate in development.

Staff management and capacity building under conditions of insecurity: lessons from developing mental health service and research programs in post-conflict Timor-Leste.
Australas Psychiatry
PUBLISHED: 09-01-2011
Show Abstract
Hide Abstract
The task of staff capacity building is particularly important, albeit challenging, in low and middle income countries emerging from prolonged periods of persecution and conflict. Mental health professionals engaged in development and research projects are acutely aware of the impact of past and current conditions including trauma exposure, insecurity, and poverty on the capacity of local workers to acquire and apply skills. In this article we reflect on these challenges by drawing on our experience spanning 10 years of mental health work and capacity building in Timor-Leste.

Neural responses to masked fear faces: sex differences and trauma exposure in posttraumatic stress disorder.
J Abnorm Psychol
PUBLISHED: 02-10-2010
Show Abstract
Hide Abstract
Although women have a greater propensity than men to develop posttraumatic stress disorder (PTSD) following trauma, sex differences in neural activations to threat have received little investigation. This study tested the prediction that trauma would heighten activity in automatic fear-processing networks to a greater extent in women than in men. Functional magnetic resonance imaging (fMRI) data were recorded in 23 participants with PTSD (13 women, 10 men), 21 trauma-exposed controls (9 women, 12 men), and 42 non-trauma-exposed controls (22 women, 20 men) while they viewed masked facial expressions of fear. Exposure to trauma was associated with enhanced brainstem activity to fear in women, regardless of the presence of PTSD, but in men, it was associated only with the development of PTSD. Men with PTSD displayed greater hippocampal activity to fear than did women. Both men and women with PTSD showed enhanced amygdala activity to fear relative to controls. The authors conclude that greater brainstem activation to threat stimuli may contribute to the greater prevalence of PTSD in women, and greater hippocampal activation in men may subserve an enhanced capacity for contextualizing fear-related stimuli.

Heterogeneity of non-conscious fear perception in posttraumatic stress disorder as a function of physiological arousal: an fMRI study.
Psychiatry Res
PUBLISHED: 03-24-2009
Show Abstract
Hide Abstract
While posttraumatic stress disorder (PTSD) is often characterised by an excessive fear response and hyperarousal, research has generally neglected other clinical characteristics including hypoarousal. Findings indicate that concurrent autonomic activity is associated with increased non-conscious processing of fear, highlighting that autonomic responsivity may be an important determinant in the degree of activation within the brainstem-amygdala-MPFC (medial prefrontal cortex) network.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
