AbstractThis study examined temporal trend, seasonality, and geographical variations of legionellosis incidence and mortality in Japan. This nationwide observational study used the Japanese Vital Statistics and Infectious Diseases Weekly Report (1999–2017) data to calculate legionellosis crude and age-adjusted incidence and mortality rates per 100,000 population by age and sex. Incidence was compared among the 4 seasons and regional incidence among 47 prefectures. Of 13,613 (11,194 men) people with legionellosis in Japan, 725 (569 men) were fatal. Increasing incidence trend occurred from 0.0004 (1999) to 1.37 (2017) per 100,000 population. People aged ≥ 70 years accounted for 43.1% overall; men’s age-adjusted incidence rate was consistently approximately five times higher than for women. Significantly higher incidence occurred in summer than in winter (p = 0.013). Geographically, highest incidence (≥ 2.0 per 100,000 population) occurred in Hokuriku District, with increasing trends in Hokkaido and middle-part of Japan. Estimated fatality rates decreased consistently at 5.9% (95% confidence interval: − 8.1, − 3.5) annually, from 1999 to 2017, with no trend change point. Increasing legionellosis incidence occurred in Japan during 1999–2017, with declining estimated fatality rates. In this aging society and warming world, disease clinical burden may further deteriorate in future due to increasing incidence trends.

AbstractJapan is still a medium-burden tuberculosis (TB) country. We aimed to examine trends in newly notified active TB incidence and TB-related mortality in the last two decades in Japan. This is a population-based study using Japanese Vital Statistics and Japan Tuberculosis Surveillance from 1997 to 2016. We determined active TB incidence and mortality rates (per 100 000 population) by sex, age and disease categories. Joinpoint regression was applied to calculate the annual percentage change (APC) in age-adjusted mortality rates and to identify the years showing significant trend changes. Crude and age-adjusted incidence rates reduced from 33.9 to 13.9 and 37.3 to 11.3 per 100 000 population, respectively. Also, crude and age-adjusted mortality rates reduced from 2.2 to 1.5 and 2.8 to 1.0 per 100 000 population, respectively. Average APC in the incidence and mortality rates showed significant decline both in men (−6.2% and −5.4%, respectively) and women (−5.7% and −4.6%, respectively). Age-specific analysis demonstrated decreases in incidence and mortality rates for every age category, except for the incidence trend in the younger population. Although trends in active TB incidence and mortality rates in Japan have favourably decreased, the rate of decline is far from achieving TB elimination by 2035.

This retrospective observational study conducted in Necker Hospital for Sick Children, France (January 2018–June 2020) evaluated a potential temporal association between admissions for suicide behaviours in children and adolescents and the national COVID-19 lockdown (March–May 2020). During the study period, 234 patients were admitted for suicide behaviours (28% male; mean age 13.4 years). Using Poisson regression, we found a significant decrease in the incidence of admissions for suicide behaviour during the lockdown (adjusted incidence rate ratio: 0.46; 95% CI 0.24 to 0.86). This association might result from reduced help-seeking and decreased hospital admission rates during the lockdown, as well as cognitive and environmental factors. Further multicentre studies should be conducted to confirm these findings and investigate whether a compensatory rise in admissions for suicide behaviour occurred in the postlockdown period.

Abstract In the era of hyper-ageing, Creutzfeldt–Jakob disease (CJD) can become more prevalent as an important cause of dementia. This study aimed to evaluate the trends in crude and age-adjusted CJD-associated mortality and incidence rates in Japan using national vital statistics data on CJD-associated deaths among individuals aged over 50 years, as well as the government-funded nationwide CJD surveillance data (pertaining to the years 2005–2014) in Japan. The data were analysed using the Joinpoint Regression Program to estimate the long-term trends and average annual percentage changes (AAPCs). Overall, the AAPCs of age-adjusted CJD-associated mortality rates rose significantly over the study period (3.2%; 95% confidence interval [CI] 1.4–5.1%). The AAPC of the age-adjusted incidence rates also increased (overall 6.4%; 95% CI 4.7–8.1%). The CJD-associated increases in the mortality and incidence rates were especially prominent among adults over the age of 70 years. Given this trend in aging of population, the disease burden of CJD will continue to increase in severity. Our findings thus recommend that policymakers be aware of the importance of CJD and focus on preparing to address the increasing prevalence of dementia.

Abstract Background On 13 March 2020, the Danish authorities imposed extensive nationwide lockdown measures to prevent the spread of the coronavirus disease 2019 (COVID-19) and reallocated limited healthcare resources. We investigated mortality rates, overall and according to location, in patients with established cardiovascular disease before, during, and after these lockdown measures. Methods and results Using Danish nationwide registries, we identified a dynamic cohort comprising all Danish citizens with cardiovascular disease (i.e. a history of ischaemic heart disease, ischaemic stroke, heart failure, atrial fibrillation, or peripheral artery disease) alive on 2 January 2019 and 2020. The cohort was followed from 2 January 2019/2020 until death or 16/15 October 2019/2020. The cohort comprised 340 392 and 347 136 patients with cardiovascular disease in 2019 and 2020, respectively. The overall, in-hospital, and out-of-hospital mortality rate in 2020 before lockdown was significantly lower compared with the same period in 2019 [adjusted incidence rate ratio (IRR) 0.91, 95% confidence interval (CI) CI 0.87–0.95; IRR 0.95, 95% CI 0.89–1.02; and IRR 0.87, 95% CI 0.83–0.93, respectively]. The overall mortality rate during and after lockdown was not significantly different compared with the same period in 2019 (IRR 0.99, 95% CI 0.97–1.02). However, the in-hospital mortality rate was lower and out-of-hospital mortality rate higher during and after lockdown compared with the same period in 2019 (in-hospital, IRR 0.92, 95% CI 0.88–0.96; out-of-hospital, IRR 1.04, 95% CI1.01–1.08). These trends were consistent irrespective of sex and age. Conclusions Among patients with established cardiovascular disease, the in-hospital mortality rate was lower and out-of-hospital mortality rate higher during lockdown compared with the same period in the preceding year, irrespective of age and sex.

Abstract Background Little is known about the bleeding risk in patients with inflammatory bowel disease (IBD) and venous thromboembolism (VTE) treated with anticoagulation. Our aim was to elucidate the rate of major bleeding (MB) events in a well-defined cohort of patients with IBD during anticoagulation after VTE. Methods This study is a retrospective follow-up analysis of a multicenter cohort study investigating the incidence and recurrence rate of VTE in IBD. Data on MB and IBD- and VTE-related parameters were collected via telephone interview and chart review. The objective of the study was to evaluate the impact of anticoagulation for VTE on the risk of MB by comparing time periods with anticoagulation vs those without anticoagulation. A random-effects Poisson regression model was used. Results We included 107 patients (52 women, 40 with ulcerative colitis, 64 with Crohn disease, and 3 with unclassified IBD) in the study. The overall observation time was 388 patient-years with and 1445 patient-years without anticoagulation. In total, 23 MB events were registered in 21 patients, among whom 13 MB events occurred without anticoagulation and 10 occurred with anticoagulation. No fatal bleeding during anticoagulation was registered. The incidence rate for MB events was 2.6/100 patient-years during periods exposed to anticoagulation and 0.9/100 patient-years during the unexposed time. Exposure to anticoagulation (adjusted incidence rate ratio, 3.7; 95% confidence interval, 1.5-9.0; P = 0.003) and ulcerative colitis (adjusted incidence rate ratio, 3.5; 95% confidence interval, 1.5-8.1; P = 0.003) were independent risk factors for MB events. Conclusion The risk of major but not fatal bleeding is increased in patients with IBD during anticoagulation. Our findings indicate that this risk may be outweighed by the high VTE recurrence rate in patients with IBD.

Aims To measure the incidence and mortality rates of ischemic stroke (IS) subtypes in Joinville, Brazil. Methods All first-ever IS patients that occurred in Joinville from January 2005 to December 2006 were identified. The IS subtypes were classified by the TOAST criteria, and the patients were followed-up for one year after IS onset. Results The age-adjusted incidence per 100,000 inhabitants was 26 (17-39) for large-artery atherosclerosis (LAA), 17 (11-27) for cardioembolic (CE), 29 (20-41) for small vessel occlusion (SVO), 2 (0.6-7) for stroke of other determined etiology (OTH) and 30 (20-43) for stroke of undetermined etiology (UND). The 1-year mortality rate per 100,000 inhabitants was 5 (2-11) for LAA, 6 (3-13) for CE, 1 (0.1-6) for SVO, 0.2 (0-0.9) for OTH and 9 (4-17) for UND. Conclusion In the population of Joinville, the incidences of IS subtypes were similar to those found in other populations. These findings highlight the importance of better detection and control of atherosclerotic risk factors.

Abstract Background Antibiotic use is common for acute respiratory infections (ARI) in children, but much of this use is inappropriate. Few studies have examined whether rurality of residence is associated with inappropriate antibiotic use. We examined whether rates of ARI-related inappropriate antibiotic use among children vary by rurality of residence. Methods We conducted a retrospective cohort study of children aged 2 months – 5 years enrolled in Tennessee Medicaid between 2007 and 2017 and diagnosed with ARI in the outpatient setting. Study outcomes included ARI, ARI-related antibiotic use, and ARI-related inappropriate antibiotic use. Multivariable Poisson regression was used to measure associations between rurality of residence, defined by the United States Census Bureau, and the rate of study outcomes, while accounting for other factors including demographics and underling comorbidities. Results 805,332 children met selection criteria and contributed 1,840,048 person-years (p-y) of observation. Children residing in completely rural, mostly rural, and mostly urban counties contributed 70,369 (4%) p-y, 479,121 (26%) p-y, and 1,290,558 p-y (70%), respectively. Compared with children in mostly urban counties (238 per 1000 p-y), children in mostly rural (450 per 1000 p-y) and completely rural counties (468 per 1000 p-y) had higher rates of inappropriate antibiotic use (adjusted incidence rate ratio [aIRR]: 1.34 (95% confidence interval [CI]: 1.33 – 1.35) and aIRR: 1.33 (CI: 1.32 – 1.35), respectively). Conclusion Inappropriate antibiotic use is common among young children with ARI, with higher rates in rural compared to urban counties. These differences should inform targeted outpatient antibiotic stewardship efforts.

Background: Cardiovascular disease (CVD) and dementia have profound impacts on the morbidity and disability burden in older people. Uncertainty remains regarding the future incidence of these conditions. We forecast future levels of morbidity and disability in England and Wales up to 2040 under two scenarios regarding CVD and dementia future trends. Methods: We developed a probabilistic Markov model (IMPACT-BAM) which follows the transitions of the England and Wales population into health states characterised by the presence or absence of CVD, dementia and disability to 2040. Data sources include national health registers (ONS) and cohort studies (HSE, Whitehall II and ELSA). Modelled CVD and Non-CVD mortality and prevalence trends for disability and morbidity were used to estimate trends in life expectancy (LE), morbidity-free life expectancy (MFLE) and disability-free life expectancy (DFLE). We assumed that CVD incidence and mortality will continue their current trends and modelled two scenarios: Scenario A assumes constant dementia incidence, a common assumption when projecting future burden of dementia; Scenario B assumes 2% annual decline in dementia incidence, as suggested in UK population-based cohorts. Results: In 2011, LE at age 65 was 18.4 years for men and 21.0 years for women. In Scenario A, LE at 65 in 2040 will increase to 26.7 and 24.8 years in men and women. DFLE at 65 will increase (by 5.5 years in men and 2.8 years in women, to 21.7 and 20.7 years respectively). MFLE at 65 will increase slightly (by 1.5 years in men and 1.4 in women, to 10.7 and 13.2 years respectively). Disability prevalence would increase by 3.1% to 14.4% ( 1,081,483 of 7,510,299) in men and decrease slightly (by 0.6% to 14% (1,214,754 of 8,676,813)) in women. In Scenario B, LE at 65 in 2040 will increase to a similar degree as in Scenario A, but DFLE and MFLE will increase faster (DFLE: by 7.5 years in men and 4.6 in women, to 23.7 and 22.5 years respectively; MFLE: by 4.5 years for both genders to 13.8 years in men and 16.3 in women). Disability prevalence will slightly increase (by 0.8% to 12.1% (908,746 of 7,510,299)) in men and decrease by 3.0% to 11.4% (989,157 of 8,676,813) in women. Conclusions: The future disability burden crucially depends on assumptions about future dementia incidence trends. If the dementia incidence continues unchanged, the duration of morbidity and disability will be prolonged. However, if dementia incidence decreases (as suggested in the UK and mirroring CVD declines) we could live more years in good health, with morbidity compressed into a shorter period before death.
