Long-Term Prevalence of Disaster-Related Deep Vein Thrombosis in Minamiaso Village After the 2016 Kumamoto Earthquakes: A Prospective Cross-Sectional Analysis.

OBJECTIVE: This study aimed to examine the prevalence of deep vein thrombosis (DVT) among evacuees in Minamiaso, a village which was temporarily isolated after the earthquakes, from the acute to recovery phase after the 2016 Kumamoto Earthquakes (GLIDE no: EQ-2016-000033-JPN). METHODS: This prospective study, which was approved by Fukui University Medical Research Ethics Committee (approval no. 20160024 and 20160089), enrolled 181 evacuees (73.9 ± 11.6 y) who participated in a series of 3 DVT screenings using portable ultrasound machines conducted over 19 mo. All participants completed a questionnaire before the screenings, and none of the participants attended all 3 screenings. Data analysis was performed using EZR version 1.41. RESULTS: The DVT prevalence was 14.3% (79.4 ± 8.2 y) at first screening of evacuees staying in shelters and 18.5% (71.5 ± 13.1 y) and 12.2% (72.8 ± 10.9 y) in second and third screenings of evacuees staying in temporary housing, respectively. Multivariate analysis revealed age ≥75 y and alcohol consumption as independent risk factors in the entire cohort and in patients aged ≤74 y, respectively. CONCLUSIONS: A high DVT prevalence over a long time period of 19 mo was observed where survivors were temporarily isolated after the disaster.

Localized Right Subclavian Artery Dissection Detected by Accident on an Ultrasound Examination: A Case Report and Literature Review.

Right subclavian artery dissection was detected in a 78-year-old female victim of the Kumamoto earthquake during a carotid artery ultrasound examination. She was subsequently taken to hospital and diagnosed with localized subclavian artery dissection (LSAD) by contrast-enhanced computed tomography. There have been no previous reports of LSAD detected at a medical checkup. LSAD may progress and become severe, even in asymptomatic patients or patients with mild symptoms, and careful long-term follow-up is therefore required in all patients diagnosed with LSAD.

Potential predictors of susceptibility to occupational stress in Japanese novice nurses - a pilot study.

BACKGROUND: Occupational stress is a known factor behind employee resignations; thus, early identification of individuals prone to such stress is important. Accordingly, in this pilot study we evaluated potential predictors of susceptibility to occupational stress in Japanese novice nurses. METHODS: Forty-two female novice nurses at Kagoshima University Hospital were recruited for the study population. Each underwent physical health and urinary examinations, and completed a lifestyle questionnaire at the time of job entry. Each also completed a Brief Job Stress Questionnaire (BJSQ), related to mental health status, at job entry and 5 months post-entry. Psychological stress, somatic symptoms, and combined BJSQ scores were determined for each time point. RESULTS: All three stress condition scores had significantly decreased at 5 months post-entry, suggesting occupational stress. Systolic blood pressure (r = -0.324, p < 0.05) and urinary sodium (r = -0.313, p < 0.05) were significantly negatively correlated with combined BJSQ score at 5 months post-entry. Post-entry stress condition scores were significantly low in subjects reporting substantial 1-year body weight change (≤ ± 3 kg) and short times between dinner and bedtimes (≤2 h), though baseline stress condition scores were not. Urinary sodium concentration, 1-year body weight change, and pre-sleep evening meals were then targeted for multivariate analysis, and confirmed as independent explanatory variables for post-entry stress condition scores. CONCLUSIONS: One-year body weight change, times between dinner and bedtimes, and urinary sodium concentration are promising potential predictors of susceptibility to occupational stress, and should be further investigated in future research.

Angle between the common and internal carotid arteries detected by ultrasound is related to intima-media thickness among those with atherosclerotic disease.

OBJECTIVES: Although carotid artery structural variations have been detected by ultrasound, their clinical significance is not fully understood. The objective of this study was to determine whether the angle between the common carotid artery (CCA) and the internal carotid artery (ICA), designated angle α, an ultrasound-detectable carotid artery structural variation, is related to carotid artery intima-media thickness (IMT), a surrogate marker for carotid atherosclerosis. METHODS: As a cross-sectional study, we measured angle α in routine carotid artery ultrasounds from 176 subjects (130 men) with atherosclerotic disease/risk factors that attended Kouseiren Hospital in Kagoshima City, Japan between August 2007 and April 2009. We evaluated the correlation between the angle α and CCA- or ICA-IMT. RESULTS: Angle α was weakly correlated with age but significantly correlated with ICA-IMT. The correlation was stronger in subjects with an ICA-IMT ≥ 0.5 mm than in those with an ICA-IMT < 0.5 mm (Right side r = 0.475 vs. 0.246, Left side r = 0.498 vs. 0.301, respectively). Upon multivariate logistic regression analysis, angle α and serum low-density lipoprotein cholesterol were independent explanatory variables for ICA-IMT. CONCLUSION: Angle α is related to ICA-IMT in subjects with atherosclerotic disease or risk factors in this study.

Thermal therapy improves left ventricular diastolic function in patients with congestive heart failure: a tissue doppler echocardiographic study.

OBJECTIVES: We previously reported that systemic thermal therapy using 60 degrees C dry sauna improves left ventricular systolic function and clinical symptoms in patients with chronic heart failure. The aim of this study was to investigate the effects of thermal therapy on left ventricular diastolic function. METHODS: We examined transmitral inflow and mitral annular velocity before and after sauna in 10 patients with congestive heart failure using pulsed and tissue Doppler echocardiography. RESULTS: Left ventricular and left atrial dimensions and left ventricular percentage fractional shortening did not change after sauna. Early diastolic mitral inflow velocity (E) increased and the deceleration time of the E wave decreased significantly after sauna compared to before sauna. Early diastolic mitral annular velocity (E') significantly increased after sauna. The deceleration time of E' significantly decreased after sauna compared to before sauna. The E/E' significantly decreased 30 min after sauna. CONCLUSIONS: Thermal therapy improves acute left ventricular diastolic function in patients with congestive heart failure.
