Posttraumatic stress moderates return intentions: a factorial survey experiment with internally displaced persons in Nigeria

Background: Persons displaced by conflict often consider returning to their area of origin. Lack of reliable information about conditions in the area of origin makes this decision more difficult. Displaced persons address this by seeking information from other sources, but must then assess the credibility of these sources.Objective: This study examines the role of symptoms of posttraumatic stress as a moderator of how information from a trustworthy source influences return intentions among displaced persons.Method: We test our hypotheses with a factorial survey experiment, drawing participants (N = 822) from residents of internally displaced person (IDP) camps in northeastern Nigeria.Results: Information from a more trustworthy source led to increased return intentions. However, the more participants reported symptoms of posttraumatic stress, the smaller the effect source trustworthiness had on their return intentions.Conclusions: Findings highlight how traumatic experiences during wartime can undermine the effectiveness of the provision of information from a trustworthy source about good conditions in displaced persons' areas of origin, and suggest that interventions addressing posttraumatic stress could have downstream effects on safe, durable, and dignified return.

Mental health disorders in population displaced by conflict in Colombia: Comparative analysis against the National Mental Health Survey 2015

BACKGROUND AND OBJECTIVES

Colombia is one of the countries with the highest levels of internal displacement resulting from armed conflict. This population has greater chances of experiencing a mental health disorder, especially in territories historically affected by armed conflict. Our objective was to compare the levels of possible mental health disorder in people experiencing internal displacement in Meta, Colombia, a department historically affected by armed conflict, compared to the internally displaced population in the National Mental Health Survey of 2015.

METHODS

Analysis of data collected in the National Mental Health Survey (ENSM) of 2015, study with representative data at national level and the Conflict, Peace and Health survey (CONPAS) of 2014, representative study of the degree of impact of the conflict on the municipality, conducted in the department of Meta, Colombia. To measure possible mental health disorder, the Self-Report Questionnaire-25 (SRQ-25) was used. Internal displacement is self-reported by people surveyed in both studies. An exploratory analysis is used to measure possible mental health disorders in the displaced population in the ENSM 2015 and CONPAS 2014.

RESULTS

1089 adults were surveyed in CONPAS 2014 and 10,870 adults were surveyed in the ENSM 2015. 42.9% (468) and 8.7% (943) of people reported being internally displaced in CONPAS 2014 and ENSM 2015, respectively. In both studies, internally displaced populations have greater chances of experiencing any mental health disorder compared to non-displaced populations. For CONPAS 2014, 21.8% (95%CI, 18.1-25.8) of this population had a possible mental health disorder (SRQ+) compared to 14.0% (95%CI, 11.8-16.3) in the ENSM 2015. Compared with the ENSM 2015, at the regional level (CONPAS 2014), displaced people had a greater chance of presenting depression by 12.4% (95%CI, 9.5-15.7) compared to 5.7% (95%CI, 4.3-7.4) in the ENSM 2015, anxiety in 21.4% (95%CI, 17.7-25.3) compared to 16.5% (95%CI, 14.2-19.1) in the ENSM 2015, and psychosomatic disorders in 52.4% (95%CI, 47.5-56.7) in CONPAS 2014 compared to 42.2% (95%CI, 39.0-45.4) in the ENSM 2015. At the national level (ENSM 2015), displaced people had greater possibilities of presenting, compared to the regional level, suicidal ideation in 11.9% (95%CI, 9.3-14.1) compared to 7.3% (95%CI, 5.0-10.0) in CONPAS 2014 and bipolar disorder in 56.5% (95%CI, 53.2-59.7) compared to 39.3% (95%CI, 34.8-43.9) in CONPAS 2014.

CONCLUSIONS

The greater possibilities of displaced populations at the regional level of experiencing a mental health disorder, compared to this same population at the national level, may represent and indicate greater needs in mental health care services in territories affected by conflict. Therefore, and given the need to facilitate access to health services in mental health for populations especially affected by armed conflict, there is a need to design health care policies that facilitate the recovery of populations affected by war and, simultaneously, that reduce inequities and promote the fulfilment of one of the most important and, at the same time, least prioritised health objectives in international development: mental health.

Deep Inspiration Breath Hold [(18)F]FDG PET-CT on 4-rings scanners in evaluating lung lesions: evidences from a phantom and a clinical study

OBJECTIVE

To investigate the clinical feasibility of a Deep Inspiration Breath Hold (DIBH) (18)F-FDG PET-CT acquisition in apnea and compare the results obtained between these acts of acquisition in apnea and in Free Breathing in the evaluation of lung lesions.

MATERIAL AND METHODS

A pre-clinical phantom study was performed to evaluate the shortest simulated DIBH time according to the minimum detectable lesion that can be detected by our ultrasound scanner. This study was conducted by changing acquisition time and sphere-to-background activity ratio values and by using radioactivity densities similar to those generally found in clinical examinations. In the clinical study, 25 patients with pulmonary lesions underwent a standard whole body (18)F-FDG PET-CT scan in free breathing followed by a 20s single thorax acquisition PET/CT in DIBH acquisition.

RESULTS

The phantom study indicated that a 20-s acquisition time provides an accurate evaluation of smallest sphere shaped lesions. In the clinical study, PET-CT scans obtained in DIBH studies showed a significant reduction of misalignment between the PET and CT scan images and an increase of SUVmax compared to free breathing acquisitions. A correlation between the %BH-index and lesion displacement between PET and CT images in FB acquisition was demonstrated, significantly higher for lesions with a displacement>8mm.

CONCLUSION

The single 20s acquisition of DIBH PET-CT is a feasible technique for lung lesion detection in the clinical setting. It only requires a minor increase in examination time without special patient training. 20s DIBH scan provided a more precise measurement of SUVmax, especially for lesions in the lower lung lobes which usually show greater displacement between PET and CT scan images in FB acquisition.
