Information on the incidence of progressive supranuclear palsy (PSP) is limited; incidence rates for multiple system atrophy (MSA) are not available. We studied the incidence of PSP and MSA in Olmsted County, Minnesota, for the years 1976 to 1990. This study was part of a larger investigation of all forms of parkinsonism. We used the medical records-linkage system of the Rochester Epidemiology Project to identify all subjects whose records contained documentation of any form of parkinsonism, related neurodegenerative diseases, or tremor of any type. A nurse abstractor screened the records and, when applicable, a neurologist reviewed them to determine the presence or absence of parkinsonism. Cases of parkinsonism were classified using specified diagnostic criteria. Population denominators were derived from census data and were corrected by removing prevalent cases of parkinsonism. Over the 15 years of the study, we found 16 incident cases of PSP and nine incident cases of MSA. No cases of PSP or MSA had onset before age 50 years. The average annual incidence rate (new cases per 100,000 person-years) for ages 50 to 99 years was 5.3 for PSP and 3.0 for MSA. The incidence of PSP increased steeply with age from 1.7 at 50 to 59 years to 14.7 at 80 to 99 years, and was consistently higher in men. Median survival time from symptom onset was 5.3 years for PSP and 8.5 years for MSA. The incidence of PSP increases with age and is consistently higher in men at all ages. PSP and MSA are more common than previously recognized.

Abstract If the observed dramatic increase in VTE incidence with advancing age is due to increased VTE risk factor exposure (i.e., secondary VTE), the incidence of idiopathic VTE should not vary with age or calendar year. Objective: To estimate the incidence of idiopathic and secondary VTE by age and by calendar year. Methods: Using the resources of the Rochester Epidemiology Project, we identified the inception cohort of Olmsted County, MN, residents with a first lifetime VTE during the 30-year period, 1966–1995 (n=2761). For each case, we reviewed the complete medical records in the community for 48 baseline clinical characteristics that are commonly-accepted risk factors for VTE. We categorized VTE cases as idiopathic (n=305) if no such characteristics were present; the remaining cases were categorized as secondary. Age- and sex-specific incidence rates were calculated using idiopathic or secondary VTE cases as the numerator, and age-, sex- and calendar year-specific estimates of the population of Olmsted County as the denominator. Results: The incidence of both idiopathic and secondary VTE increased exponentially with age for both men and women (p<0.001). Over the 30-year study period, the age-adjusted incidence of idiopathic VTE was essentially constant among men (from 19.0 to 17.1 per 100,000 men-years for 1966–70 and 1990–95, respectively), but decreased markedly among women (from 18.5 to 3.6 per 100,000 woman-years for 1966–70 and 1990–95, respectively; p=0.005 for the interaction). Conclusions: The dramatic increase in VTE incidence with age likely reflects the biology of aging, although as yet unidentified VTE risk factors cannot be excluded. The reason for the decreased incidence of idiopathic VTE over the last 30 years among women is unclear.

Background: There is growing concern about the rising incidence and prevalence of food allergy globally. We previously reported the incidence of food allergy in Olmsted County, Minnesota, between 2002 and 2011. We sought to update the incidence and temporal trends of food allergies in our region through 2018. Methods: By using the Rochester Epidemiology Project, all Olmsted County residents, with an incident diagnosis of food allergy between January 2, 2012, and December 31, 2018, were identified and their medical records were reviewed. These cases were combined with the previously collected incidence cases from January 2, 2002, and December 31, 2011, to understand longitudinal trends in food allergy incidence rates. Results: Over the 17-year study period, 1076 patients (58.0% male patients, 72.1% white) were diagnosed with an incident food allergy. The median (interquartile range) age at first diagnosis was 2.0 years (1.1-8.4 years). The overall annual incidence rate for all ages was 3.9 (95% confidence interval [CI], 3.6‐4.1) per 10,000 person-years and was significantly higher in male than in female patients (4.4 [95% CI, 4.0‐4.7] and 3.3 [95% CI, 3.0‐3.6], respectively; p < 0.001). The most common food allergen was egg in infancy (57.7%), peanuts in ages 1‐4 years (58.3%), tree nuts in ages 5‐18 years (57.4%), and seafood in adults (≥19 years) (45.3%). Conclusion: The incidence of food allergy in Olmsted County steadily increased from 2002 to 2008, then remained relatively stable between the years 2008 and 2013, and again presented a rising trend over the next 5 years until 2018. This warrants further investigations into the effects of changes in guidelines for early introductions of allergenic foods and other factors that affect causality.

BACKGROUND Cutaneous leishmaniasis (CL) is endemic in the Middle East, with countries such as Syria reporting high incidence rates. OBJECTIVE This study aimed to assess the trends in the incidence of cutaneous leishmaniasis (CL) in Jordan from 2010 to 2016. METHODS This retrospective study included all cases of CL that had been reported to the Leishmaniasis Surveillance System in the Department of Communicable Diseases at the Jordan Ministry of Health during the period from 2010 to 2016. A total of 1243 cases were reported and met the case definition. RESULTS A total of 1243 cases (60.65% [754/1243] males and 39.34% [489/1243] females) were diagnosed during the study period. Of this sample, 233 patients (19.13%) were aged &lt;5 years old, 451 (37.03%) were aged between 5-14 years old, 190 (15.60%) were aged between 15-24 years old, and 344 (28.24%) were aged ≥25 years old. Of those, 646 (51.97%) were Jordanians and 559 (44.97%) were Syrians. The average annual incidence rate of 1.70 per 100,000 people between 2010 and 2013 increased to 3.00 per 100,000 people in the years 2014 to 2016. There was no difference in incidence rates between Jordanians and Syrian refugees between 2010 and 2012. After 2012, the incidence rate increased significantly among Syrian refugees from 1.20 per 100,000 people in 2012 to 11.80 per 100,000 people in 2016. On the contrary, the incidence rate did not change significantly among Jordanians. CONCLUSIONS The incidence rate of leishmaniasis in Jordan has increased in the last three years because of the influx of Syrian refugees into Jordan. A massive effort toward reservoir and vector control, along with actively pursuing diagnosis in endemic foci, will be helpful. Proper and studious reporting of cases is also a necessity for the eradication of this disease.

Abstract Abstract 2256 Background: The incidence of venous thromboembolism (VTE) may be increasing due to the obesity epidemic. Objective: To estimate the incidence of VTE and describe trends in incidence adjusted for the population's increase in BMI. Methods: Using the resources of the Rochester Epidemiology Project, we identified all Olmsted County, MN residents with an incident deep vein thrombosis (DVT) or pulmonary embolism (PE) over the 13-year period, 1988–2000 (n=1,400). Age and BMI at VTE diagnosis and gender were collected for all cases. Age was categorized into 10 year intervals. Using a model for the population distribution of BMI derived from several (n=6) non-VTE Olmsted County cohorts (n=8,011 individuals), we calculated the probability of falling into each of five BMI categories (<18.5, 18.5–24, 25–29, 30–34, 35+) for each age, gender and calendar year. In Olmsted County in the median age group, the prevalence of BMI >30 kg/m2increased from approximately 15% in 1980 to 36% in 2000. We applied these probabilities to the decennial census data for 1980, 1990, 2000 using linearly interpolated census values for intra-census years to obtain Olmsted County age/sex/calendar year/BMI category denominators. Generalized linear modeling assuming a Poisson error structure, and using a log link function, and a log (population) offset was used to assess the relationship of crude incidence rates to gender, year of diagnosis, age and BMI. Results: The overall average age- and sex-adjusted annual VTE incidence was 120 per 100,000 person-years (DVT: 66 per 100,000; PE: 54 per 100,000), with higher age-adjusted rates among men than women (129 versus 113 per 100,000, respectively). VTE incidence rates increased exponentially with age for both genders, ranging from 3 to 1,079 per 100,000 for age groups 0–19 to 90–110 years. Age and sex-adjusted VTE incidence increased by increasing BMI category (88, 112, 106, 150, and 195 per 100,000 person-years, respectively, by increasing BMI category). Unadjusted for BMI, VTE incidence was unchanged from 1988 through 2000 (p=0.70). After adjusting for age, gender and calendar year, VTE incidence increased with increasing BMI (p<0.0001). The calendar year incidence slope estimate decreased numerically from 3% per decade to minus 4% per decade after adjusting for increasing BMI, remaining nonsignificant (p=0.57). Conclusions: VTE remains a major national health problem, especially among the obese. Despite the dramatically increasing population BMI, and the significant association of BMI category with VTE incidence, the overall incidence of VTE remained unchanged over the timeframe, 1988–2000. Disclosures: No relevant conflicts of interest to declare.

SYNOPSISNumerous studies have estimated the frequency of bulimia nervosa among high school girls and college women, but population-based trends in incidence in a community have not been reported.In this study we determined the incidence of bulimia nervosa by identifying persons residing in the community of Rochester, Minnesota, who had the disorder initially diagnosed during the 11-year period from 1980 to 1990. Using our comprehensive population-based data resource (the Rochester Epidemiology Project), we identified cases by screening 777 medical records with diagnoses of bulimia; feeding disturbance; rumination syndrome; adverse effects of cathartics, emetics, or diuretics; polyphagia; sialosis; or vomiting.We identified 103 Rochester residents (100 female and 3 male) who fulfilled DSM-III-R diagnostic criteria for bulimia nervosa during the 11-year study period. Mean ± S.D. age for females at the time of diagnosis was 23·0 ± 6·1 years (range, 14·4 to 40·2 years). Yearly incidence in females rose sharply from 7·4 per 100000 population in 1980 to 49·7 in 1983, and then remained relatively constant around 30 per 100000 population. The annual age-adjusted incidence rates were 26·5 per 100000 population for females and 0·8 per 100000 population for males. The overall age-and sex-adjusted annual incidence was 13·5 per 100000 population.Bulimia nervosa is a common disorder in adolescent girls and young women from 15 to 24 years of age. Histories of alcohol or drug abuse, depression, or anorexia nervosa were higher than expected in the general population.

Background Spontaneous intracranial hypotension is diagnosed with an increasing frequency, but epidemiologic data are scarce. The aim of this study was to determine the incidence rate of spontaneous intracranial hypotension in a defined population. Methods Using a prospectively maintained registry, all patients with spontaneous intracranial hypotension residing in Beverly Hills, California, evaluated at our Medical Center between 2006 and 2020 were identified in this population-based incidence study. Our Medical Center is a quaternary referral center for spontaneous intracranial hypotension and is located within 1.5 miles from downtown Beverly Hills. Results A total of 19 patients with spontaneous intracranial hypotension were identified. There were 12 women and seven men with a mean age of 54.5 years (range, 28 to 88 years). The average annual incidence rate for all ages was 3.7 per 100,000 population (95% confidence interval [CI]: 2.0 to 5.3), 4.3 per 100,000 for women (95% CI, 1.9 to 6.7) and 2.9 per 100,000 population for men (95% CI, 0.8 to 5.1). Conclusion This study, for the first time, provides incidence rates for spontaneous intracranial hypotension in a defined population.

Objective: To investigate time trends in the incidence of parkinsonism and PD over a 15-year period (1976 to 1990).Methods: The authors used the medical records–linkage system of the Rochester Epidemiology Project to identify incidence cases of parkinsonism in Olmsted County, MN, over three 5-year periods, 1976 to 1980, 1981 to 1985, and 1986 to 1990. PD and other types of parkinsonism were classified using defined criteria. Population denominators were derived from census data and were corrected by removing prevalent cases of parkinsonism.Results: Over the 15 years of the study, 364 cases of parkinsonism were identified; 154 (42%) of them had PD. The incidence of parkinsonism remained stable over the three 5-year periods for the age classes 0 to 39, 40 to 59, and 60 to 69 years. For the age class 70 to 99 years, there was some increase over time mainly owing to an increased incidence of drug-induced parkinsonism. The incidence of PD remained stable over the three 5-year periods for all age classes. Results were similar when considering men and women separately. No birth-cohort effect was present for parkinsonism. Comparison with three previous studies in the same population did not reveal any major long-term secular trends in the incidence of parkinsonism.Conclusions: The findings for PD over 15 years and comparison of the findings with historical data for parkinsonism over half a century suggest that no major environmental risk factors for PD (e.g., environmental toxins, drugs, diet constituents, or infectious agents) were introduced or removed from this population during these periods.

IntroductionThe incidence and prevalence of diabetes within a population are important public health metrics. Pharmaceutical administrative data may offer a resource that can contribute to quantifying these measures using the recorded signals derived from the drugs used to treat people with diabetes. ObjectiveTo estimate the longitudinal incidence and prevalence of drug treated (DT) diabetes in Australia utilising an Australian Pharmaceutical Benefits Scheme (PBS) dataset and compare estimates with community survey data for all diabetes reported in the Australian National Health Survey (NHS). MethodsPersons with DT diabetes were identified within the PBS dataset using assigned Anatomic Therapeutic Chemical codes for `Drugs used in diabetes'. Prevalent persons with DT diabetes were determined by a single annual treatment, and incident cases from the earliest treatment with diabetes medications. Counts were aggregated by age group and utilised Australian national census data as a denominator to calculate diabetes disease frequencies for the period 2004--14. Comparison of PBS prevalence data was made with NHS surveys over equivalent years. ResultsThe age adjusted incidence of DT diabetes was 3.4/1000 in 2006 and increased to 3.8/1000 in 2011 and 5.1/1000 in 2014. Age adjusted prevalence of DT diabetes in Australia also rose from 26.7/1000 in 2006 to 32.1/1000 in 2011 and 42.1/1000 in 2014. DT diabetes prevalence estimates correlated with NHS estimates of self-reported diabetes prevalence across age groups and in 2014 was r = 0.987. However, PBS estimates of DT diabetes prevalence generally underestimated NHS values of self-reported diabetes in older age groups with mean percentage differences of -22% to -3%. In contrast, PBS data captured more younger persons with diabetes in comparison to NHS data. These differences were then used to adjust DT diabetes incidence rates to provide age specific estimates that could potentially reflect diabetes incidence estimates acquired by community survey. ConclusionsPBS data representing dispensed medications prescribed to persons with diabetes offers a perspective for the assessment of diabetes incidence and prevalence. PBS derived DT diabetes prevalence estimates correlate well with community survey estimates of self-reported diabetes, but underestimate NHS data in older age groups. Calibrated DT incidence estimates may potentially reflect community survey derived diabetes incidence estimates and may offer a method for longitudinal monitoring.

AbstractNursing home (NH) residency is an independent risk factor for venous thromboembolism (VTE), but the VTE burden within the NH population is uncertain. This study estimates VTE incidence and VTE-associated mortality among NH residents. We identified all NH residents in any NH in Olmsted County, Minnesota, United States, 1 October 1998 to 31 December 2005 and all first lifetime VTE among county residents to estimate VTE incidence while resident of local NHs (NHVTE), using Centers for Medicare and Medicaid Services Minimum Data Set and Rochester Epidemiology Project resources. We tested associations between NHVTE and age, sex and time since each NH admission using Poisson modelling. Additionally, we tested incident NHVTE as a potential predictor of survival using Cox proportional hazards, adjusting for age, sex and NH residency. Between 1 October 1998 and 31 December 2005, 3,465 Olmsted County residents with ≥1 admission to a local NH, contributed 4,762 NH stays. Of the 3,465 NH residents, 111 experienced incident NHVTE (2.3% of all eligible stays), for an overall rate of 3,653/100,000 NH person-years (NH-PY). VTE incidence was inversely associated with time since each NH admission, and was highest in the first 7 days after each NH admission (18,764/100,000 NH-PY). The adjusted hazard of death for incident NHVTE was 1.90 (95% confidence interval [CI]: 1.38–2.62). In conclusion, VTE incidence among NH residents was nearly 30-fold higher than published incidence rates for the general Olmsted County population. VTE incidence was highest within 7 days after NH admission, and NHVTE was associated with significantly reduced survival. These data can inform future research and construction of clinical trials regarding short-term prophylaxis.

ObjectiveDiagnostic criteria from 2002 classify transverse myelitis (TM) as idiopathic or disease associated but predate the discovery of aquaporin-4 (AQP4)–immunoglobulin G (IgG) and myelin oligodendrocyte glycoprotein (MOG)-IgG, which associate with TM. Prior incidence estimates of idiopathic TM (ITM) range from 1 to 6.2 per 1 million. We sought to determine whether the population-based incidence and prevalence of ITM were reduced by testing patients with ITM for AQP4/MOG-IgG and reclassifying seropositive cases as having disease-associated TM.MethodsFor this observational study, we retrospectively identified all cases of incident (January 1, 2003–December 31, 2016) and prevalent (December 31, 2016) ITM in Olmsted County (85% white) by using the Rochester Epidemiology Project medical records linkage system. ITM was defined by the 2002 Transverse MyelitisConsortium Working Group diagnostic criteria. Available sera were tested for AQP4-IgG and MOG-IgG.ResultsTwenty-four patients (incident 22, prevalent 17) initially met 2002 ITM criteria (longitudinally extensive TM [LETM] 6). Sera were tested for AQP4-IgG in 22 of 24 (92%) and MOG-IgG in 21 of 24 (88%). Three seropositive cases (AQP4-IgG 2, MOG-IgG 1) were identified and reclassified as having disease-associated TM, accounting for 14% of total incident and 12% of total prevalent cases. AQP4-IgG and MOG-IgG seropositive cases represented 50% (3 of 6) of idiopathic LETM. After reclassification of seropositive patients, the final ITM incidence was 8.6 per 1,000,000 and prevalence was 7.9 per 100,000. Three cases of ITM (14%) subsequently fulfilled multiple sclerosis criteria within the study period.ConclusionsThe availability of AQP4-IgG and MOG-IgG modestly reduced ITM incidence and prevalence, which remained higher than previously reported in this predominantly white population. Incorporation of these biomarkers into future revisions of TM diagnostic criteria should be considered.
