Seasonal Variation and Severity of Acute Abdomen in Japan: A Nine-Year Retrospective Analysis.

ABSTRACT: The seasonal incidence of acute abdomens, such as appendicitis, is reportedly more common in summer but is reported less frequently in Asia. Additionally, seasonal variations in the severity of acute abdomens have been evaluated insufficiently. This study evaluated the seasonal variations in the incidence and severity of acute abdomens in Japan. This retrospective observational study used a multicenter database containing data from 42 acute hospitals in Japan. We included all patients diagnosed with acute appendicitis, diverticulitis, cholecystitis, and cholangitis between January 2011 and December 2019. Baseline patient data included admission date, sequential organ failure assessment score, presence of sepsis, and disseminated intravascular coagulation. We enrolled 24,708 patients with acute abdomen. Seasonal admissions for all four acute abdominal diseases were the highest in summer [acute appendicitis, (OR = 1.35; 95% CI = 1.28-1.43); diverticulitis, (OR = 1.23; 95% CI = 1.16-1.31; cholecystitis (OR = 1.23; 95% CI = 1.11-1.36); and cholangitis (OR = 1.23; 95% CI = 1.12-1.36)]. The proportion of patients with sepsis and disseminated intravascular coagulation as well as the total SOFA score for each disease, did not differ significantly across seasons. Seasonal variations in disease severity were not observed.

Project description:OBJECTIVES:Our aim was to assess seasonal variation in home blood pressure (BP) among free-living nationwide participants using home BP values accumulated from a web-based healthcare platform established in Japan. SETTINGS:An observational study. OMRON Healthcare Co., Ltd. has been developing web-based personal healthcare record systems in Japan since November 2010; over two million voluntary participants had joined this platform in September 2015. Nationwide home BP measurements made by oscillometric-type electronic sphygmomanometers from over 110 000 voluntary participants have been transmitted to the system from devices. PARTICIPANTS:Seasonal variation in home BP was evaluated among 64?536 (51 335 men, 13?201 women; mean age 52.9 years) free-living nationwide users for whom data were automatically and simultaneously transmitted to the system from devices. PRIMARY OUTCOME MEASURES:Mean monthly and weekly home BP. RESULTS:In multiple regression analysis, the relationship between BP and temperature was a significant inverse association, independent of age, gender and geological locations. Highest and lowest BP was observed in December and July, respectively. Substantial seasonal differences in the mean values of morning and evening home systolic BP between summer and winter were 6.2?mmHg and 5.5?mmHg in men, and 7.3?mmHg and 6.5?mmHg in women. Seasonal variation was a little greater in older (7.3?mmHg in men, 8.7?mmHg in women) than in younger individuals (5.8?mmHg in men, 6.5?mmHg in women). BP from February to July was approximately 1.5?mmHg lower than the value from August to December. CONCLUSIONS:A web-based healthcare platform has enabled easier monitoring of population-wide BP. Tighter BP control is necessary in winter than in summer, and especially in a colder climate toward winter than toward summer. New technologies using web-based self-monitoring systems for health-related indexes are expected to initiate a new phase of cardiovascular disease prevention and public health promotion.
