Social Capital and Post-traumatic Stress Disorder among Heavy Rainfall and Flood Victims in Japan.

This study examined the relationship between cognitive/structural social capital and post-traumatic stress disorder (PTSD) among victims of heavy rain and flood. Participants were individuals aged≥18 years affected by the July 2018 heavy rainfall in the cities of Kurashiki and Soja, Japan, and living in temporary housing. We distributed five copies of a questionnaire to 1,991 households and received responses from 1,927 individuals (907 men, 1,008 women, 12 respondents of unspecified sex) in 1,029 households (51.7%). We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between high (vs. low) social capital and PTSD or other outcomes. After covariate adjustment, the odds of having PTSD were lower in participants with high cognitive social capital than those with low cognitive social capital (OR=0.346, 95%CI: 0.263-0.456). Elderly women with higher structural social capital tended to have lower PTSD odds than those with lower structural social capital (OR=0.671, 95%CI: 0.431-1.046). The opposite pattern was observed for elderly men (OR=1.315, 95%CI: 0.792-2.183). Cognitive social capital is a protective factor that may reduce PTSD or promote a favorable PTSD prognosis after heavy rainfall and flood events. The associations between structural social capital and PTSD differ by age and sex.

[Clinical characteristics of patients with workplace-associated mood disorder --comparison with non-workplace-associated group].

AIM: The purpose of this study was to describe the clinical characteristics of patients with workplace-associated mood disorder. METHOD: We conducted a clinical survey involving 84 clinical cases (regular employees suffering from mood disorder) who were hospitalized in the Psychiatry Department of Jichi Medical University Hospital, for a period over 8 years and 4 months between April 1st, 2000 and July 31st, 2008. RESULTS: The size of the workplace-associated group as a percentage of those patients in whom the onset of the symptom was occasioned by an evident issue at their workplace was 65%. This rate accounted for 74% of the total patients if clinical cases in which an evident issue at the workplace served as a significant trigger for the symptom were added to these patients in the case of an initial episode in the "non-workplace associated group". In the workplace-associated group, cases in which the premorbid character was a "depression-related personality" comprised only 42%, and was noticeably characterized by a perfection-oriented habit, enthusiastic character, conformity with other people, etc. Furthermore, the percentage of patients who were diagnosed with a "depression-related personality" comprised only 59% of the "overworked group", in which a heavy workload was evident in the workplace-associated group. In the workplace-associated group, the percentage of cases involving managerial workers was significantly high; their rate as initial cases was significantly high, as well the proportion of favorable outcomes. In the workplace-associated group, the percentage of patients who showed unambiguous depression at the initial stage was significantly low. Likewise, a similar result was obtained in the overworked group. CONCLUSIONS: Workplace-associated mood disorder today tends to have a stress-related aspect, or aspect of adjustment disorder. There was a period in many cases during which the main symptoms were insomnia, headache, panic attack, etc., prior to the onset of unambiguous depression in the workplace-associated mood disorder group. In depression associated with workplace-associated mood disorder, there are two pathological stages. The stage of adjustment disorder is the period in which such conditions are the main symptoms, and a serious or moderate stage of major depressive disorder is the period after full-scale depression develops in the wake of the former stage. What contributes to protection against depression are a proper diagnosis of depression whose pathological condition is at an early adjustment disorder stage and appropriate therapeutic measures.

SMARCA4-deficient thoracic tumor detected by [18F]FDG PET/CT.

BACKGROUND: SMARCA4-deficient thoracic tumor (SMARCA4-DTT) is a distinct entity of undifferentiated thoracic malignancies newly introduced in 2015. Due to its unique clinical characteristic with aggressive thoracic tumor mostly observed in heavy smoker man with emphysema, with poor prognosis, many physicians are becoming increasingly aware of the disease; however, reports on 2-deoxy-2-[18F] fluoroglucose positron emission tomography/computed tomography ([18F]FDG PET/CT) have been limited; thus, this disease is not yet widely known to nuclear medicine clinicians. As a first step in discussing the usefulness of [18F]FDG PET/CT for this disease, we present a case in which [18F]FDG PET/CT played a clinically important role. CASE: A 74-year-old heavy smoker man with an anamnesis of severe emphysema characterized by pleural thickening and abnormal enhancement in CT underwent 18F-FDG PET/CT for further examination. [18F]FDG-avid pleural nodules infiltrating into the chest wall were detected and pathologically diagnosed as SMARCA4-DTT with biopsy. CONCLUSION: SMARCA4-deficient thoracic tumor should be considered in a [18F]FDG-avid aggressive thoracic tumor in heavy smoker men with emphysema.
