Objectives The aim of the study was to describe the morbidity pattern of different diagnostic categories in insured cats in Japan by age, sex and breed. Methods The annual incidence rates of having at least one insurance claim were calculated overall and stratified by diagnosis, age, sex and breed using data from insured cats in the period April 2008 to March 2013. Results The overall annual incidence rate of having at least one insurance claim was 4632 (95% confidence interval 4608–4656) cats per 10,000 cat-years at risk. The highest annual incidence rate was obtained for digestive system disorders, followed by urinary tract disorders and dermatological disorders. The incidence rates varied between breeds for most diagnostic categories: for cardiovascular system disorders, Scottish Fold, American Shorthair, Persian, Maine Coon, Norwegian Forest Cat, Ragdoll and Bengal had a higher annual incidence rate than crossbreeds. Conclusions and relevance This study provides comparative and quantitative estimates of morbidity pattern in insured Japanese cats. These estimates can be utilised by veterinary practitioners, breeders and owners in diagnostic decision-making, breeding and when selecting a new pet, respectively.

Stroke In Young Adults

Numerous hospital-based stroke registries have been developed in Iran during last decade. Khorasan Stroke Registry, Khorasan Posterior Circulation Stroke Registry, Khorasan Pediatric Stroke Registry and Khorasan Stroke in Young Adults Registry are among these published registries. Meanwhile, There is only one epidemiologic deigned study of stroke in Iran and Middle East. Based on this standard epidemiologic study; The crude annual incidence rate of First Ever Stroke (FES) is 139 (95% CI, 128 to 149) per 100 000; for men, 144 (95% CI, 128 to 159), and for women, 133 (95% CI, 118 to 148). The incidence rates increases significantly with each decade of life and is similar in men and women. Subtypes of FES in 81.9%  of patients is ischemic stroke,12.7% is intracerebral hemorrhage, and 2.4% have subarachnoid hemorrhage. The crude annual incidence rate per 100 000 inhabitants is 113 (95% CI, 104 to 123) for ischemic stroke, 18 (95% CI, 14 to 21) for intracerebral hemorrhage and 3 (95% CI, 2 to 5) for subarachnoid hemorrhage. Ischemic strokes are occurring approximately 1 decade earlier in Iran than in other countries.

Object Pituitary tumors are abnormal growths that develop in the pituitary gland. The Central Brain Tumor Registry of the United States (CBTRUS) contains the largest aggregation of population-based data on the incidence of primary CNS tumors in the US. These data were used to determine the incidence of tumors of the pituitary and associated trends between 2004 and 2009. Methods Using incidence data from 49 population-based state cancer registries, 2004–2009, age-adjusted incidence rates per 100,000 population for pituitary tumors with ICD-O-3 (International Classification of Diseases for Oncology, Third Edition) histology codes 8040, 8140, 8146, 8246, 8260, 8270, 8271, 8272, 8280, 8281, 8290, 8300, 8310, 8323, 9492 (site C75.1 only), and 9582 were calculated overall and by patient sex, race, Hispanic ethnicity, and age at diagnosis. Corresponding annual percent change (APC) scores and 95% confidence intervals were also calculated using Joinpoint to characterize trends in incidence rates over time. Diagnostic confirmation by subregion of the US was also examined. Results The overall annual incidence rate increased from 2.52 (95% CI 2.46–2.58) in 2004 to 3.13 (95% CI 3.07–3.20) in 2009. Associated time trend yielded an APC of 4.25% (95% CI 2.91%–5.61%). When stratifying by patient sex, the annual incidence rate increased from 2.42 (95% CI 2.33–2.50) to 2.94 (95% CI 2.85–3.03) in men and 2.70 (95% CI 2.62–2.79) to 3.40 (95% CI 3.31–3.49) in women, with APCs of 4.35% (95% CI 3.21%–5.51%) and 4.34% (95% CI 2.23%–6.49%), respectively. When stratifying by race, the annual incidence rate increased from 2.31 (95% CI 2.25–2.37) to 2.81 (95% CI 2.74–2.88) in whites, 3.99 (95% CI 3.77–4.23) to 5.31 (95% CI 5.06–5.56) in blacks, 1.77 (95% CI 1.26–2.42) to 2.52 (95% CI 1.96–3.19) in American Indians or Alaska Natives, and 1.86 (95% CI 1.62–2.13) to 2.03 (95% CI 1.80–2.28) in Asians or Pacific Islanders, with APCs of 3.91% (95% CI 2.88%–4.95%), 5.25% (95% CI 3.19%–7.36%), 5.31% (95% CI –0.11% to 11.03%), and 2.40% (95% CI –3.20% to 8.31%), respectively. When stratifying by Hispanic ethnicity, the annual incidence rate increased from 2.46 (95% CI 2.40–2.52) to 3.03 (95% CI 2.97–3.10) in non-Hispanics and 3.12 (95% CI 2.91–3.34) to 4.01 (95% CI 3.80–4.24) in Hispanics, with APCs of 4.15% (95% CI 2.67%–5.65%) and 5.01% (95% CI 4.42%–5.60%), respectively. When stratifying by age at diagnosis, the incidence of pituitary tumor was highest for those 65–74 years old and lowest for those 15–24 years old, with corresponding overall age-adjusted incidence rates of 6.39 (95% CI 6.24–6.54) and 1.56 (95% CI 1.51–1.61), respectively. Conclusions In this large patient cohort, the incidence of pituitary tumors reported between 2004 and 2009 was found to increase. Possible explanations for this increase include changes in documentation, changes in the diagnosis and registration of these tumors, improved diagnostics, improved data collection, increased awareness of pituitary diseases among physicians and the public, longer life expectancies, and/or an actual increase in the incidence of these tumors in the US population.

Objective.To determine the incidence of systemic lupus erythematosus (SLE) and SLE with concomitant or subsequent lupus nephritis (LN) in Denmark during 1995–2011, using data from the Danish National Patient Registry (NPR).Methods.To assess the incidence of SLE, we identified all persons aged ≥ 18 years in the NPR with at least 1 International Classification of Diseases, 10th ed (ICD-10) code of SLE and at least 365 days of followup under this diagnosis. Identification of LN cases was based on fulfillment of these criteria and ≥ 1 registration under an ICD-10 code of nephritis concomitantly with or after first SLE registration.Results.The overall annual incidence rate per 100,000 for SLE was 2.35 (95% CI 2.24–2.49); 0.69 (95% CI 0.60–0.78) for men and 3.96 (95% CI 3.75–4.17) for women. For LN, the mean annual incidence rate per 100,000 was estimated to be 0.45 (95% CI 0.38–0.53); 0.20 (95% CI 0.13–0.28) for men and 0.69 (95% CI 0.57–0.83) for women. The differences in SLE incidence rates between sexes decreased by age, and the incidence did not differ between men and women after the age of 60 years for LN. The estimated incidences showed no trends by calendar time. Estimated overall point prevalence (December 31, 2011) per 100,000 was 45.2 (95% CI 43.3–47.4) and 6.4 (95% CI 5.7–7.2) for SLE and LN, respectively.Conclusion.Our Danish population-based data showed a stable incidence of SLE and LN. As expected, we found higher incidence rates among women than among men, particularly in younger persons.

OBJECTIVEOnly a few previous studies have investigated subarachnoid hemorrhage (SAH) after surgical treatment in patients with unruptured intracranial aneurysms (UIAs). Given the improvement in long-term outcomes of embolization, more extensive data are needed concerning the true rupture rates after microsurgery in order to provide reliable information for treatment decisions. The purpose of this study was to investigate the incidence of and risk factors for postoperative SAH in patients with surgically treated UIAs.METHODSData from 702 consecutive patients harboring 852 surgically treated UIAs were evaluated. Surgical treatments included neck clipping (complete or incomplete), coating/wrapping, trapping, proximal occlusion, and bypass surgery. Clippable UIAs were defined as UIAs treated by complete neck clipping. The annual incidence of postoperative SAH and risk factors for SAH were studied using Kaplan-Meier survival analysis and Cox proportional hazards regression models.RESULTSThe patients’ median age was 64 years (interquartile range [IQR] 56–71 years). Of 852 UIAs, 767 were clippable and 85 were not. The mean duration of follow-up was 731 days (SD 380 days). During 1708 aneurysm years, there were 4 episodes of SAH, giving an overall average annual incidence rate of 0.23% (95% CI 0.12%–0.59%) and an average annual incidence rate of 0.065% (95% CI 0.0017%–0.37%) for clippable UIAs (1 episode of SAH, 1552 aneurysm-years). Basilar artery location (adjusted hazard ratio [HR] 23, 95% CI 2.0–255, p = 0.0012) and unclippable UIA status (adjusted HR 15, 95% CI 1.1–215, p = 0.046) were significantly related to postoperative SAH. An excellent outcome (modified Rankin Scale score of 0 or 1) was achieved in 816 (95.7%) of 852 cases overall and in 748 (98%) of 767 clippable UIAs at 12 months.CONCLUSIONSIn this large case series, microsurgical treatment of UIAs was found to be safe and effective. Aneurysm location and unclippable morphologies were related to postoperative SAH in patients with surgically treated UIAs.

The aim of this work was to study modern manifestations of seasonal brucellosis among the population of the Republic of Tajikistan. The materials and methods: of the study were the official statistics, as well as the results of previously performed studies on the risk assessment of the incidence in population. A retrospective epidemiological analysis of annual incidence rate for the period from 1997 to 2016 was conducted, depending on the most significant social and environmental risk factors. Results. The article shows the impact on the annual incidence rate of socio-economic transformations, including the privatization of collective livestock farms, accompanied by the massive movement of farm animals to private ownership, the loss of practice in animal breeding, and changes in environmental and climatic conditions. Against the background of the intensification of sheep breeding, there is a tendency in seasonality smoothing and shifting the maximum levels of population incidence of brucellosis to the spring season. Conclusion. The modern features of seasonal manifestation of brucellosis infection in the Republic of Tajikistan make it necessary to apply a differentiated approach to planning and conducting preventive measures in various areas of the country.

Enhanced surveillance for dengue virus (DENV) infections in Italy has been implemented since 2012, with annual reports from the National Health Institute. In this study, we summarize available evidence on the epidemiology of officially notified DENV infections from 2010–2021. In total, 1043 DENV infection cases were diagnosed, and most of them occurred in travelers, with only 11 autochthonous cases. The annual incidence rates of DENV infections peaked during 2019 with 0.277 cases per 100,000 (95% confidence interval [95% CI] 0.187–0.267), (age-adjusted incidence rate: 0.328, 95% CI 0.314–0.314). Cases of DENV were clustered during the summer months of July (11.4%), August (19.3%), and September (12.7%). The areas characterized by higher notification rates were north-western (29.0%), and mostly north-eastern Italy (41.3%). The risk for DENV infection in travelers increased in the time period 2015–2019 (risk ratio [RR] 1.808, 95% CI 1.594–2.051) and even during 2020–2021 (RR 1.771, 95% CI 1.238–2.543). Higher risk for DENV was additionally reported in male subjects compared with females subjects, and aged 25 to 44 years, and in individuals from northern and central Italy compared to southern regions and islands. In a multivariable Poisson regression model, the increased number of travelers per 100 inhabitants (incidence rate ratio [IRR] 1.065, 95% CI 1.036–1.096), the incidence in other countries (IRR 1.323, 95% CI 1.165–1.481), the share of individuals aged 25 to 44 years (IRR 1.622, 95% CI 1.338–1.968), and foreign-born residents (IRR 2.717, 95% CI 1.555–3.881), were identified as effectors of annual incidence. In summary, although the circulation of DENV remains clustered among travelers, enhanced surveillance is vital for the early detection of human cases and the prompt implementation of response measures.

IntroductionIndividual and household-level evidence suggests a relationship between food insecurity and cholera risk. The relationship between national food security and the size of cholera outbreaks is unknown.MethodsWe analysed the relationship between national food security and annual cholera incidence rate from 2012 to 2015 across 30 countries. We used components of the Global Food Security Index (GFSI) as measures of food security. We included countries with available GFSI reporting cases of cholera during the study period, excluding high-income countries. We developed multivariable zero-inflated negative binomial models with annual cholera incidence rate as the outcome, GFSI components as the exposure of interest, fixed effects for country and year, and time-varying effects related to water, sanitation, and hygiene, oral cholera vaccine deployment, healthcare expenditure, conflict and extreme weather.ResultsThe 30 countries reported 550 106 total cases of cholera from 2012 to 2015, with a median annual incidence rate of 3.1 cases per 100 000 people (IQR 0.3–9.9). We found independent inverse relationships between cholera and Overall GFSI (incidence rate ratio (IRR) 0.57, 95% CI 0.43 to 0.78), GFSI-Availability (IRR 0.81, 95% CI 0.70 to 0.95) and GFSI-Affordability (IRR 0.76, 95% CI 0.62 to 0.92).ConclusionsWe identified a strong inverse relationship between national food security and annual incidence rate of cholera. In the context of prior evidence at the individual and household levels, this suggests that there is a linkage between food insecurity and cholera at the national level that should be further considered in assessing cholera risk in vulnerable regions and in designing cholera control interventions.

ObjectiveMitral stenosis increases the risk of atrial fibrillation (AF) and stroke. Large data underlying the trend in incidence, treatment and outcomes of mitral stenosis are lacking.MethodsBased on the Health Insurance Review and Assessment Service database in Republic of Korea, patients who were diagnosed with mitral stenosis between 2007 and 2016 were enrolled. Trends in the incidence rate and changing patterns of treatment and outcome for stroke and systemic embolism and intracranial haemorrhage (ICH) were analysed.ResultsA total of 42 075 patients (mean age 60.7±13.5 years, 13 303 (31.6%) male) were included in the present study. The number included 27 824 (66.1%) patients with mitral stenosis and comorbid AF. The age-standardised annual incidence rate per 100 000 of mitral stenosis in Korea decreased remarkably from 10.3 to 3.6 over 10 years. The use of anticoagulation therapy increased consistently. The annual incidence of stroke and systemic embolism showed signs of plateau, while the incidence of ICH increased.ConclusionsThe overall incidence rate of mitral stenosis in Korean population has decreased remarkably. As increasing the use of vitamin K antagonist, the annual incidence rate of ICH was increased but the rate of stroke incidence reached a plateau. Alternative effective anticoagulation strategy should be investigated.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is frequently present in patients with mitral regurgitation (MR). Currently, there is a lack of real-world evidence specifically addressing the clinical performance of direct oral anticoagulants (DOACs) in patients with AF and concomitant MR. Therefore, the aim of the present study was to assess the efficacy and safety profile of DOACs therapy in patients with AF and MR. Methods: Data for this study were sourced from the Atrial Fibrillation Research Database in the Department of Cardiology at Monaldi Hospital. The database was queried for AF patients with MR who were prescribed DOACs therapy. The primary safety outcome was defined as the annual incidence rate of major bleeding events and the primary effectiveness outcome as the annual incidence rate of all events classified as ischemic stroke, transient ischemic attacks, and systemic embolisms. Results: Consecutive AF patients with concomitant mild to severe MR who received DOACs therapy (n = 259) were included. Patients were dichotomized in 2 groups according to MR severity: a mild-to-moderate group (MR 1-2+; n = 151) and a moderate-to-severe group (MR 3-4+; n = 108). The incidence rate of major bleedings was significantly higher in MR 3-4+ group (3.92%) compared with the MR 1-2+ group (1.18%; hazard ratio [HR]: 3.2; 95% CI: 1.4-7.3; P = .0059). The incidence rate of thromboembolic events between MR 3-4+ group (0.66%) and MR 1-2+ group (0.62%) was not significantly different (HR: 0.75; P = .823). Conclusions: In the present study, there was no difference in the efficacy profile of DOACs between AF patients with mild-to-moderate and moderate-to-severe MR. Considering the increased bleeding risk, a close and careful follow-up should be warranted for patients with moderate-to-severe MR.
