OBJECTIVE There have been no accurate surveillance data regarding the incidence rate of spinal arteriovenous shunts (SAVSs). Here, the authors investigate the epidemiology and clinical characteristics of SAVSs. METHODS The authors conducted multicenter hospital-based surveillance as an inventory survey at 8 core hospitals in Okayama Prefecture between April 1, 2009, and March 31, 2019. Consecutive patients who lived in Okayama and were diagnosed with SAVSs on angiographic studies were enrolled. The clinical characteristics and the incidence rates of each form of SAVS and the differences between SAVSs at different spinal levels were analyzed. RESULTS The authors identified a total of 45 patients with SAVSs, including 2 cases of spinal arteriovenous malformation, 5 cases of perimedullary arteriovenous fistula (AVF), 31 cases of spinal dural AVF (SDAVF), and 7 cases of spinal epidural AVF (SEAVF). The crude incidence rate was 0.234 per 100,000 person-years for all SAVSs including those at the craniocervical junction (CCJ) level. The incidence rate of SDAVF and SEAVF combined increased with advancing age in men only. In a comparative analysis between upper and lower spinal SDAVF/SEAVF, hemorrhage occurred in 7/14 cases (50%) at the CCJ/cervical level and in 0/24 cases (0%) at the thoracolumbar level (p = 0.0003). Venous congestion appeared in 1/14 cases (7%) at the CCJ/cervical level and in 23/24 cases (96%) at the thoracolumbar level (p < 0.0001). CONCLUSIONS The authors reported detailed incidence rates of SAVSs in Japan. There were some differences in clinical characteristics of SAVSs in the upper spinal levels and those in the lower spinal levels.

Background/AimsLymphomas are the most frequent neoplasm of the orbit. However, the epidemiology of orbital lymphomas is not well reported. This study aimed to provide a population-based report on the epidemiology of orbital lymphomas and measure the trends in the incidence of orbital lymphoma cancer in South Korea.MethodsNationwide cancer incidence data from 1999 to 2016 were obtained from the Korea Central Cancer Registry. Age-standardised incidence rates and annual percent changes were calculated according to sex and histological types. The analysis according to the Surveillance, Epidemiology, and End Results summary stage classifications was performed from 2006 to 2016. Survival rates were estimated for cases diagnosed from 1999 to 2016.ResultsA total of 630 patients (median age: 54 years) with orbital lymphoma in the orbital soft tissue were included in this study. The age-standardised incidence rates increased from 0.03 to 0.08 per 100 000 individuals between 1999 and 2016, with an annual percent change of 6.61%. The most common histopathological type of orbital lymphoma was extra marginal zone B cell lymphoma, accounting for 82.2% of all orbital lymphomas during 1999–2016, followed by diffuse large B cell lymphoma (9.2%). Five-year, 10-year and 15-year overall survival (OS) of orbital lymphoma was 90.8%, 83.8% and 75.8%, respectively. OS showed a significant decrease as age increased and no significant differences between men and women.ConclusionThe incidence rate of orbital lymphoma is very low in South Korea. However, the incidence rate has increased over the past years. Orbital lymphomas have a worse prognosis as age increases.

ObjectiveTo summarise the unfolding of the COVID-19 epidemic among slum dwellers and different social strata in the city of Buenos Aires during the first 20 weeks after the first reported case.DesignObservational study using a time-series analysis. Natural experiment in a big city.SettingPopulation of the city of Buenos Aires and the integrated health reporting system records of positive RT-PCR for COVID-19 tests.ParticipantsRecords from the Argentine Integrated Health Reporting System for all persons with suspected and RT-PCR-confirmed diagnosis of COVID-19 between 31 January and 14 July 2020.OutcomesTo estimate the effects of living in a slum on the standardised incidence rate of COVID-19, corrected Poisson regression models were used. Additionally, the impact of socioeconomic status was performed using an ecological analysis at the community level.ResultsA total of 114 052 people were tested for symptoms related with COVID-19. Of these, 39 039 (34.2%) were RT-PCR positive. The incidence rates for COVID-19 towards the end of the 20th week were 160 (155 to 165) per 100 000 people among the inhabitants who did not reside in the slums (n=2 841 997) and 708 (674 to 642) among slums dwellers (n=233 749). Compared with the better-off socioeconomic quintile (1.00), there was a linear gradient on incidence rates: 1.36 (1.25 to 1.46), 1.61 (1.49 to 1.74), 1.86 (1.72 to 2.01), 2.94 (2.74 to 3.16) from Q2 to Q5, respectively. Slum dwellers were associated with an incidence rate of 14.3 (13.4 to 15.4).ConclusionsThe distribution of the epidemic is socially conditioned. Slum dwellers are at a much higher risk than the rest of the community. Slum dwellers should not be considered just another risk category but an entirely different reality that requires policies tailored to their needs.

AbstractHIV incidence in sub-Saharan Africa declined substantially between 2000 and 2015. In this analysis, we consider the relative associations of nine structural and individual determinants with this decline. A linear mixed effects model of logged HIV incidence rates versus determinants was used. The data were from mathematical modelling as part of the 2019 Global Burden of Disease Study in 43 sub-Saharan African countries. We used forwards selection to determine a single final model of HIV incidence rate. The association of economic variables and HIV knowledge with incidence was found to be driven by education, while ART coverage had the largest impact on other determinants’ coefficients. In the final model, education years per capita contributed the most to explaining variation in HIV incidence rates; a 1-year increase in mean education years was associated with a 0.39 (− 0.56; − 0.2, t = − 4.48 p < 0.01) % decline in incidence rate while a unit increase in ART coverage was associated with a 0.81 (− 1.34; − 0.28, t = − 3.01, p < 0.01) % decline in incidence rate.

The risk of major amputation is higher after urgently planned endovascular therapy for chronic limb-threatening ischemia (CLTI) in patients with diabetes mellitus (DM). The aim of this nationwide cohort study was to compare outcomes between patients with and without DM following urgently planned open revascularization for CLTI from 2010 to 2014. Out of 1537 individuals registered in the Swedish Vascular Registry, 569 were registered in the National Diabetes Register. A propensity score adjusted Cox regression analysis was conducted to compare outcome between the groups with and without DM. Median follow-up was 4.3 years and 4.5 years for patients with and without DM, respectively. Patients with DM more often had foot ulcers ( p = 0.034) and had undergone more previous amputations ( p = 0.001) at baseline. No differences in mortality, cardiovascular death, major adverse cardiovascular events (MACE), or major amputation were observed between groups. The incidence rate of stroke was 70% higher (95% CI: 1.11–2.59; p = 0.0137) and the incidence rate of acute myocardial infarction (AMI) 39% higher (95% CI: 1.00–1.92; p = 0.0472) among patients with DM in comparison to those without. Open vascular surgery remains a first-line option for a substantial number of patients with CLTI, especially for limb salvage in patients with DM. The higher incidence rates of stroke and AMI among patients with DM following open vascular surgery for infrainguinal CLTI require specific consideration preoperatively with the aim of optimizing medical treatment to improve cardiovascular outcome postoperatively.

This study reports age- and sex-specific incidence rates of juvenile idiopathic arthritis (JIA) in complete Danish birth cohorts from 1992 through 2002. Data were obtained from the Danish registries. All persons born in Denmark, from 1992–2002, were followed from birth and until either the date of first diagnosis recording, death, emigration, 16th birthday or administrative censoring (17 May 2017), whichever came first. The number of incident JIA cases and its incidence rate (per 100,000 person-years) were calculated within sex and age group for each of the birth cohorts. A multiplicative Poisson regression model was used to analyze the variation in the incidence rates by age and year of birth for boys and girls separately. The overall incidence of JIA was 24.1 (23.6–24.5) per 100,000 person-years. The rate per 100,000 person-years was higher among girls (29.9 (29.2–30.7)) than among boys (18.5 (18.0–19.1)). There were no evident peaks for any age group at diagnosis for boys but for girls two small peaks appeared at ages 0–5 years and 12–15 years. This study showed that the incidence rates of JIA in Denmark were higher for girls than for boys and remained stable over the observed period for both sexes.

Abstract Background The prevalence and incidence rate of atrial fibrillation (AF) increase worldwide and AF is a risk factor for more adverse cardiovascular diseases including stroke. Approximately 44% of AF cases cannot be explained by common individual risk factors and risk might therefore also be related to the environment. By studying geographical variation and clustering in risk of incident AF adjusted for socioeconomic position at an individual level, potential neighbourhood risk factors could be revealed. Methods Initially, yearly AF incidence rates 1987–2015 were estimated overall and stratified by income in a register-based cohort study. To examine geographical variation and clustering in AF, we used both spatial scan statistics and a hierarchical Bayesian Poisson regression analysis of AF incidence rates with random effect of municipalities (n = 98) in Denmark in 2011–2015. Results The 1987–2015 cohort included 5,453,639 individuals whereof 369,800 were diagnosed with an incident AF. AF incidence rate increased from 174 to 576 per 100,000 person-years from 1987 to 2015. Inequality in AF incidence rate ratio between highest and lowest income groups increased from 23% in 1987 to 38% in 2015. We found clustering and geographical variation in AF incidence rates, with incidence rates at municipality level being up to 34% higher than the country mean after adjusting for socioeconomic position. Conclusions Geographical variations and clustering in AF incidence rates exist. Compared to previous studies from Alberta, Canada and the United States, we show that geographical variations exist in a country with free access to healthcare and even when accounting for socioeconomic differences at an individual level. An increasing social inequality in AF was seen from 1987 to 2015. Therefore, when planning prevention strategies, attention to individuals with low income should be given. Further studies focusing on identification of neighbourhood risk factors for AF are needed.

Abstract Background We previously reported that valvular heart disease (VHD) was not at the significant risk of stroke/systemic embolism (SE), but was associated with an increased risk of hospitalization for heart failure (HF) in Japanese atrial fibrillation patients. However, the impact of combined VHD on clinical outcomes has been little known. Purpose The aim of this study is to investigate the prevalence of combined VHD and its clinical characteristics and impact on outcomes such as stroke/SE, all-cause death, cardiac death and hospitalization for HF. Method The Fushimi AF Registry is a community-based prospective survey of AF patients in one of the wards of our city which is a typical urban district of Japan. We started to enroll patients from March 2011, and follow-up data were available for 4,466 patients by the end of November 2019. In the entire cohort, echocardiography data were available for 3,574 patients. 68 AF patients with prosthetic heart valves were excluded and we compared clinical characteristics and outcomes between 488 single VHD (103 Aortic valve disease (AVD), 315 mitral valve disease (MVD), 70 tricuspid valve disease (TVD)) and 158 combined VHD (46 AVD and MVD, 11 AVD and TVD, 66 MVD and TVD, 35 AVD and MVD and TVD). Result Compared with single VHD, patients with combined VHD were older (combined vs. single VHD: 78.5 vs. 76.0 years, respectively; p&lt;0.01), more likely to have persistent/permanent type AF (73.4% vs. 63.9%, p=0.02) and prescription of warfarin (63.1% vs. 53.8%, p=0.04). Combined VHD was less likely to have diabetes mellitus (13.9% vs. 23.6%, p=0.01) and dyslipidemia (26.6% vs. 40.4%, p&lt;0.01). Sex, body weight, hypertension, pre-existing HF were comparable between the two groups. During the median follow-up of 1,474 days, the incidence rate of stroke/SE was not significantly different between the two groups (1.58 vs. 1.89 per 100 person-years, respectively, log rank p=0.10). The incidence rate of all-cause death (7.35 vs. 5.33, p=0.65), cardiac death (1.20 vs. 0.99, p=0.91) and hospitalization for HF (5.55 vs. 4.43, p=0.53) were also not significantly different. We previously reported AVD had significant impacts on cardiac adverse outcomes in AF patients, and we further analyzed event rates between combined VHD including AVD (AVD and MVD/TVD) and without AVD (MVD and TVD). Combined VHD with AVD group had higher incidence rate of all-cause death (10.7 vs. 5.79, p=0.03) than that without AVD group. However, the incidence rate of stroke/SE (1.98 vs. 1.56, p=0.59), cardiac death (0.98 vs. 1.14, p=0.68), hospitalization for HF (8.03 vs. 5.38, p=0.17) were not significantly different between the two groups. Conclusion As compared with single VHD, the risk of stroke/SE, all-cause death, cardiac death and hospitalization for HF in combined VHD was not significantly different. Among patients with combined VHD, those having AVD had higher incidence rate of all-cause death than those without AVD. Figure 1 Funding Acknowledgement Type of funding source: None

Poisonings cause considerable morbidity and mortality worldwide. However, only few countries have published nationwide statistics on poisoning deaths. Based on the Official Cause-of-Death Statistics of Finland, we investigated the incidence and secular trend of poisoning deaths in Finland in 1971–2005. Alcohol poisoning deaths and other poisoning deaths were analyzed separately. During the 35-year study period, other poisoning deaths (non-alcohol) increased from 2.6/100,000 in men and 1.4/100,000 in women in 1971 to 6.8/100,000 and 3.2/100,000 in 2005, respectively. Alcohol poisoning death rates also increased from 9.6/100,000 in men and 0.7/100,000 in women in 1971 to 16.8/100,000 and 4.2/100,000 in 2005, respectively. In the early 1970s, the incidence rates of alcohol deaths were about 10 times higher in men compared with women, whereas in the last few years of observation, men's incidence rate was only about four times higher. Our study showed that alcohol and other poisoning deaths increased in Finland between 1971 and 2005. Men’s risk was markedly higher than women’s risk, but in the later years, women’s risk was increasing. Poisoning death rates among children and adolescents were low throughout the period.

Swelled cans were collected over a 17-month period from outlets of two supermarket food chains. Each swelled can was classified by product and the probable cause of the swelled condition. Using weekly sales volume data for each outlet, the incidence rate of swelled cans for each type of food was estimated. The incidence rates ranged from 2.1 to 78.4 swelled cans per 100,000 units sold, depending upon the type of food. Of the 1.104 swelled cans collected, 314 (28.4%) were found to have major container defects which were assumed to have resulted in the swelled condition. Microbiological analyses were performed on the products in the remaining 790 cans; the following results were obtained: (a) typical leaker spoilage, 86%; (b) typical underprocessing spoilage, 7%; (c) thermophilic spoilage, 1% and (d) nonmicrobial swells, 6%. Using vacuum testing and double seam measurements, the causes of the leakage were determined as follows: (a) poor or questionable quality canner's end double seam, 51%; (b) leaks at locations other than the double seam, 26% and (c) poor or questionable quality manufacturer's end double seam, 4%. It was concluded that examining swelled cans of low-acid foods at the retail level is a valid method for evaluating the canning operation of commercial food processing.
