Objectives The aim of this study was to describe the incidence of feline dystocia with respect to breed. Methods The data used were reimbursed claims for veterinary care insurance and/or life insurance claims in cats registered in a Swedish insurance database from 1999–2006. Results The incidence rates for dystocia were about 22 cats per 10,000 cat-years at risk, 67 per 10,000 for purebred cats and seven per 10,000 for domestic shorthair cats. The median age was 2.5 years. A significant effect of breed was seen. An incidence rate ratio (IRR) that was significantly higher compared with other purebred cats was seen in the British Shorthair (IRR 2.5), the Oriental group (IRR 2.2), Birman (IRR 1.7), Ragdoll (IRR 1.5) and the Abyssinian group (IRR 1.5). A significantly lower IRR was seen in the Norwegian Forest Cat (IRR 0.38), the Maine Coon (IRR 0.48), the Persian/Exotic group (IRR 0.49) and the Cornish Rex (IRR 0.50). No common factor among the high-risk breeds explained their high risk for dystocia. There was no effect of location; that is, the incidence rate did not differ depending on whether the cat lived in an urban or rural area. Caesarean section was performed in 56% of the cats with dystocia, and the case fatality was 2%. Conclusions and relevance The incidence rate for dystocia was of a similar magnitude in purebred cats as in dogs. The IRR varied significantly among breeds, and the main cause for dystocia should be identified separately for each breed. A selection for easy parturitions in breeding programmes is suggested.

Abstract Background:Cutaneous leishmaniasis (CL) is an important public health concern worldwide. Iran is among the most CL-affected countries, being listed as one of the first six endemic countries in the world. In order to develop targeted interventions, we performed a spatial-time visualization of CL cases in an urban area to identify high-risk and low-risk areas during 2016-2019.Methods:This cross-sectional study was conducted in the city of Mashhad. Patient data were gathered from Mashhad health centers. All cases (n=2425) were diagnosed in two stages; the initial diagnosis was based on clinical findings. Subsequently, clinical manifestation was confirmed by parasitological tests. The data were aggregated at the neighborhood and district levels and smoothed CL incidence rates per 100,000 individuals were calculated using the spatial empirical Bayesian approach. Furthermore, we used the Anselin Local Moran’s I statistic to identify clusters and outliers of CL distribution during 2016-2019 in Mashhad. Results:The overall incidence rates decreased from 34.6 per 100,000 in 2016 to 19.9 per 100,000 individuals in 2019. Both cluster analyses by crude incidence rate and smoothed incidence rate identified high-risk areas in southwestern Mashhad over the study period. Furthermore, the analyses revealed low-risk areas in northeastern Mashhad over the same 3-year period.Conclusions:The southwestern area of Mashhad had the highest CL incidence rates. This piece of information might be of value to design tailored interventions such as running effective resource allocation models, informed control plans and implementation of efficient surveillance systems. Furthermore, this study generates new hypotheses to test potential relationships between socio-economic and environmental risk factors and incidence of CL in areas with higher associated risks.

Abstract Trimodal or bimodal age-specific incidence rates for Burkitt lymphoma (BL) were observed in the United States general population, but the role of immunosuppression could not be excluded. Incidence rates, rate ratios, and 95% confidence intervals for BL and other non-Hodgkin lymphoma (NHL), by age and CD4 lymphocyte count categories, were estimated using Poisson regression models using data from the United States HIV/AIDS Cancer Match study (1980-2005). BL incidence was 22 cases per 100 000 person-years and 586 for non-BL NHL. Adjusted BL incidence rate ratio among males was 1.6× that among females and among non-Hispanic blacks, 0.4× that among non-Hispanic whites, but unrelated to HIV-transmission category. Non-BL NHL incidence increased from childhood to adulthood; in contrast, 2 age-specific incidence peaks during the pediatric and adult/geriatric years were observed for BL. Non-BL NHL incidence rose steadily with decreasing CD4 lymphocyte counts; in contrast, BL incidence was lowest among people with ≤ 50 CD4 lymphocytes/μL versus those with ≥ 250 CD4 lymphocytes/μL (incidence rate ratio 0.3 [95% confidence interval = 0.2-0.6]). The bimodal peaks for BL, in contrast to non-BL NHL, suggest effects of noncumulative risk factors at different ages. Underascertainment or biological reasons may account for BL deficit at low CD4 lymphocyte counts.

Abstract Background Native Americans in the southwestern United States (US) may be at higher risk for invasive infections due to Staphylococcus aureus. The objective of this study was to determine the burden of invasive S. aureus among Native Americans on the Navajo Nation. Methods Prospective population and laboratory-based surveillance for invasive S. aureus infections was conducted from May 2016 through April 2018. A case was defined as a Native American individual living on or around the Navajo Nation with S. aureus isolated from a normally sterile body site. Incidence rates were calculated using the Indian Health Service User Population from 2016 and 2017 as the denominators for Years 1 and 2, respectively. Age-standardized incidence rates were calculated using US Census data from 2015 as the reference group. Results 363 cases were identified (Year 1: 159; Year 2: 204). Most cases were adults (96.9%; median age: 56.0 years) and had ≥1 underlying medical condition (94.5%), of which the most common were diabetes (63.2%), hypertension (39.1%), and obesity (37.2%). 38.0% of cases were categorized as community acquired and 28.7% of infections were methicillin-resistant (MRSA). 83.2% of cases were hospitalized, 10.7% required amputation, and 6.5% died within 30 days of the initial culture. The overall incidence of invasive S. aureus was 74.4 per 100,000 persons (95% confidence interval [CI]: 67.1, 82.4) with a significantly higher incidence in the second year (Year 1: 64.9; Year 2: 84.0; incidence rate ratio: 1.29; 95% CI: 1.05, 1.59). The overall incidence of invasive MRSA was 21.3 per 100,000 persons (95% CI: 17.6, 25.8) with no significant difference by year (Year 1: 21.2; Year 2: 21.4; incidence rate ratio: 1.01; 95% CI: 0.69, 1.48). The incidence of invasive S. aureus and MRSA increased with age and was highest among individuals ≥65 years of age. The overall age-standardized incidence of invasive MRSA was 25.9 per 100,000 persons (Year 1: 26.0; Year 2: 25.7; for comparison US 2015 general population: 18.8 per 100,000 persons). Conclusion The Navajo Nation has a higher burden of invasive MRSA than the general US population. Further research is needed to evaluate trends over time and identify prevention strategies and opportunities for intervention. Disclosures All authors: No reported disclosures.

Background: The aim of this study was to explore temporal trends in incidence and case fatality rates of intracerebral hemorrhage (ICH) over the last two decades in a Norwegian municipality. Methods: Incident cases of primary ICH were registered in the period from 1995 through 2012 in 32,530 participants of the longitudinal population-based Tromsø Study. Poisson regression models were used to obtain incidence rates over time in age- and sex-adjusted and age- and sex-specific models. Case fatality rates were calculated and age- and sex-adjusted trends over time were estimated using logistic regression. Results: A total of 226 ICHs were registered. The age- and sex-adjusted incidence rate [95% confidence interval (CI)] in the overall population was 0.42 (0.37-0.48) per 1,000 person-years. Age-adjusted incidence rates were 0.53 (0.43-0.62) in men and 0.33 (0.26-0.39) in women. In individuals aged <75 years, the age- and sex-adjusted incidence rate was 0.27 (0.22-0.32) and in individuals aged ≥75 years, it was 2.42 (1.95-2.89) per 1,000 person-years. There was no significant change in incidence rates over time. The incidence rate ratio (95% CI) in the overall population was 0.73 (0.47-1.12) in 2012 compared with 1995. The overall 30-day case fatality (95% CI) was 23.9% (18.3-29.5) and did not change substantially over time [odds ratio in 2012 vs. 1995 = 0.83 (95% CI 0.27-2.52)]. Conclusion: No significant changes in incidence and case fatality rates of ICH were observed during the last two decades.

Lymphangioleiomyomatosis (LAM) is a destructive cystic lung disease. Mammalian target of rapamycin (mTOR) inhibitors are the primary treatment for LAM but it is unknown whether these immunosuppressing medications increase the risk for or the severity of respiratory infections in LAM patients.We searched multiple databases for original articles that reported the rate of respiratory infections in LAM patients treated with mTOR inhibitors or placebo. We calculated incidence rates for respiratory infections in these groups and incidence rate ratios for respiratory infections and severe respiratory infections in mTOR inhibitors treated versus placebo treated patients.11 studies were included. There were 294 patients in the treatment groups and 93 patients in the placebo groups. Among subjects in placebo arms, the incidence rate of respiratory infections was 58.8 per 100 patient-years (95% CI 35.3–82.3 per 100 patient-years). The incidence-rate ratio (IRR) for respiratory infection among treated subjects was 0.71 (95% CI 0.50–1.02; p=0.06 compared to placebo subjects). The IRR for severe respiratory infections among treated subjects was 1.56 (95% CI 0.43–8.55; p=0.52).We found that respiratory infections are common in patients with LAM. Importantly, treatment with mTOR inhibitors does not increase the incidence of these infections and may be protective.

People deprived of liberty (PDL) are at high risk of acquiring Mycobacterium tuberculosis infection (latent tuberculosis infection [LTBI]) and progressing to active tuberculosis (TB). We sought to determine the incidence rates and factors associated with LTBI and active TB in Colombian prisons. Using information of four cohort studies, we included 240 PDL with two-step tuberculin skin test (TST) negative and followed them to evaluate TST conversion, as well as, 2,134 PDL that were investigated to rule out active TB (1,305 among people with lower respiratory symptoms of any duration, and 829 among people without respiratory symptoms and screened for LTBI). Latent tuberculosis infection incidence rate was 2,402.88 cases per 100,000 person-months (95% CI 1,364.62–4,231.10) in PDL with short incarceration at baseline, and 419.66 cases per 100,000 person-months (95% CI 225.80–779.95) in individuals with long incarceration at baseline (who were enrolled for the follow after at least 1 year of incarceration). The TB incidence rate among PDL with lower respiratory symptoms was 146.53 cases/100,000 person-months, and among PDL without respiratory symptoms screened for LTBI the incidence rate was 19.49 cases/100,000 person-months. History of Bacillus Calmette-Guerin vaccination decreased the risk of acquiring LTBI among PDL who were recently incarcerated. Female sex, smoked drugs, and current cigarette smoking were associated with an increased risk of developing active TB. This study shows that PDL have high risk for LTBI and active TB. It is important to perform LTBI testing at admission to prison, as well as regular follow-up to control TB in prisons.

362 Background: mTOR inhibitors are approved in several malignancies including renal cell carcinoma (RCC). While pulmonary toxicities are a recognized adverse effect associated with this drug class, the frequency and risk of these side effects have not been well characterized. Methods: Clinical trials of mTOR inhibitors in solid tumors were identified through a search of PubMed and ASCO abstracts. Prospective studies of temsirolimus, everolimus, and ridaforolimus in solid tumors were evaluated for inclusion. 22 eligible phase II and phase III trials that included 4,242 patients were identified and included in a systematic review and meta-analysis. Adverse event data was extracted for pulmonary complications including pneumonitis, dyspnea, and cough. The incidence rate and the incidence rate ratios were determined for these pulmonary adverse events. Results: Based on our analysis of the 20 trials that reported pneumonitis, the incidence rate of any grade pneumonitis in patients with solid tumors treated with mTOR inhibitors is 0.11 (95% CI, 0.06-0.17). The incidence rate of grade 3 or 4 pneumonitis is 0.03 (95% CI, 0.01-0.04). The incidence rate ratio of any grade pneumonitis with mTOR inhibitors relative to controls is 18.9 (95% CI, 6.5-55.1), and the incidence rate ratio for the development of grade 3 or 4 pneumonitis is 7.9 (95% CI, 2.6-24.0). The incidence rates of any grade cough and dyspnea were found to be 0.23 (95% CI, 0.20-0.27) and 0.15 (95% CI, 0.10-0.21), respectively. The incidence rates of grade 3 or 4 cough and dyspnea are found to be 0.01 (95% CI, 0.00-0.01) and 0.03 (95% CI, 0.02-0.04), respectively. There was a statistically significant, but modest increase in risk of developing any grade cough (incidence rate ratio of 1.9 [95% CI, 1.6-2.4]) and grade 3 or 4 dyspnea (incidence rate ratio of 2.0 [95% CI, 1.2-3.3]) with mTOR inhibitors relative to controls. Conclusions: This study confirms that mTOR inhibitors are associated with pulmonary adverse events and provides a quantitative estimation of the risk of these adverse events in solid tumor patients treated with these drugs. The majority of pulmonary adverse events are low grade.

Abstract The objective was to measure the association between badger culling and bovine tuberculosis (TB) incidents in cattle herds in three areas of England between 2013–2017 (Gloucestershire and Somerset) and 2015–2017 (Dorset). Farming industry-selected licensed culling areas were matched to comparison areas. A TB incident was detection of new Mycobacterium bovis infection (post-mortem confirmed) in at least one animal in a herd. Intervention and comparison area incidence rates were compared in central zones where culling was conducted and surrounding buffer zones, through multivariable Poisson regression analyses. Central zone incidence rates in Gloucestershire (Incidence rate ratio (IRR) 0.34 (95% CI 0.29 to 0.39, p < 0.001) and Somerset (IRR 0.63 (95% CI 0.58 to 0.69, p < 0.001) were lower and no different in Dorset (IRR 1.10, 95% CI 0.96 to 1.27, p = 0.168) than comparison central zone rates. The buffer zone incidence rate was lower for Gloucestershire (IRR 0.64, 95% CI 0.58 to 0.70, p < 0.001), no different for Somerset (IRR 0.97, 95% CI 0.80 to 1.16, p = 0.767) and lower for Dorset (IRR 0.45, 95% CI 0.37 to 0.54, p < 0.001) than comparison buffer zone rates. Industry-led culling was associated with reductions in cattle TB incidence rates after four years but there were variations in effects between areas.

Background: Health disparities related to environmental exposure exist in different industries. Cancer is currently a leading cause of morbidity and mortality worldwide. Much remains unknown about the types of work and industries that face the greatest cancer risks. In this study, we aimed to provide the overall and specific cancer incidences among all workers from 2004 to 2015. We also aimed to show the all-cause mortality for all employees with a first-ever cancer diagnosis. Methods: All workers in Taiwan in the labor insurance database in 2004–2015 were linked to the national health insurance databases. The annual overall and specific cancer incidences in 2004–2015 were calculated and stratified by industry and gender. Age-standardized incidence rates were also calculated. Results: A total of 332,575 workers (46.5% male) who had a first-ever cancer diagnosis from 2004–2015 were identified from 16,720,631 employees who provided 1,564,593 person-years of observation. The fishing, wholesale, construction, and building industries were identified as high-risk industries, with at least 5% of employees within them receiving a first-ever cancer diagnosis. Temporal trends of cancer incidences showed a range from 235.5 to 294.4 per 100,000 with an overall upward trend and an increase of 1.3-fold from 2004 to 2015. There were significant increases over that time for breast cancer (25%); colon cancer (8%); lung, bronchial, and tracheal cancers (11%); and oral cancer (1.7%). However, the incidence rates of cervical cancer and liver and intrahepatic cholangiocarcinoma decreased by 11.2% and 8.3%, respectively. Among the 332,575 workers with a first-ever cancer diagnosis, there were 110,692 deaths and a mortality rate of 70.75 per 1000 person-years. Conclusions: The overall incidence of cancer increased over the 10-year study period, probably due to the aging of the working population. High-risk industries are concentrated in the labor-intensive blue-collar class, which is related to aging and socioeconomic status intergradation.

Abstract Background Native Americans in the southwestern United States (US) have a higher risk of many infectious diseases than the general US population. The objective of this study was to determine the burden of invasive Staphylococcus aureus disease among Native Americans on the White Mountain Apache (WMA) Tribal lands. Methods Prospective population and laboratory-based surveillance for invasive S. aureus infections was conducted from May 2016 through April 2018. A case was defined as a Native American individual living on or around the WMA Tribal lands with S. aureus isolated from a normally sterile site. Incidence rates were calculated using the Indian Health Service User Population as the denominator. Age-standardized incidence rates were calculated by direct standardization methods using US Census data from 2015 as the reference. Results Fifty-three cases were identified (Year 1: 24; Year 2: 29). Most cases were adults (90.6%; median age: 47.4 years) and had ≥1 underlying medical condition (86.8%), of which the most common were obesity (50.0%) and diabetes (50.0%). 26.4% of cases were categorized as community acquired. Most infections were methicillin-resistant (MRSA; 75.5%). 88.7% of cases were hospitalized, 7.5% required amputation, and 7.7% died within 30 days of the initial culture. The overall incidence of invasive S. aureus was 156.3 per 100,000 persons (95% confidence interval [CI]: 119.4, 204.5) with no significant difference in the incidence by year (Year 1: 141.5; Year 2: 171.1; incidence rate ratio: 1.21; 95% CI: 0.70, 2.08). The overall incidence of invasive MRSA was 118.0 per 100,000 persons (95% CI: 86.5, 160.8) with no significant difference by year (Year 1: 106.1; Year 2: 129.8; incidence rate ratio: 1.22; 95% CI: 0.66, 2.28). The incidence of invasive S. aureus and MRSA increased with age and was highest among individuals 50–64 years of age. The overall age-adjusted incidence of invasive MRSA was 138.2 per 100,000 persons (Year 1: 125.2; Year 2: 150.9, for comparison US 2015 general population: 18.8 per 100,000 persons). Conclusion The WMA community has one of the highest reported incidence rates globally of invasive MRSA. Interventions are urgently needed in this community to reduce the morbidity and mortality associated with these infections. Disclosures All Authors: No reported Disclosures.
