ObjectivePopulation-based studies on colorectal malignant polyps (MPs) are scarce. The aim of this study was to describe time trends in the incidence of colorectal MPs before and after the introduction of a colorectal mass-screening programmein 2003 and to assess outcomes (survival and recurrence) after endoscopic or surgical resection in patients with MPs.DesignWe included 411 patients with MPs diagnosed between 1982 and 2011 in a well-defined population. Age-standardised incidence rates were calculated. Univariate and multivariate 5-year recurrence and net survival analyses were performed according to gross morphology.ResultsAge-standardised incidence of MPs in patients aged 50–74 years doubled from 5.4 in 1982–2002 to 10.9 per 100 000 in 2003–2011. Pedunculated MPs were more frequently resected endoscopically (38.2%) than were sessile MPs (19.1%; p<0.001). For patients with pedunculated MPs and a pathological margin ≥1 mm, the 5 -year cumulative recurrence rate did not differ significantly between surgical and endoscopic resection (8.2% and 2.4%, respectively). For patients with sessile MPs, it was 3.0% after first-line or second-line surgical resection, 8.6% after endoscopic resection and 17.9% after transanal resection (p=0.016). The recurrence rate decreased dramatically for patients with sessile MPs from 11.3% (1982–2002) to 1.2% (2003–2009) (p=0.010) and remained stable for pedunculated MPs at 4.6% and 6.7%, respectively. Five-year net survival was 81.0% when pathological margins were <1 mm and 95.6% when ≥1 mm (p=0.024).ConclusionOutcomes following polypectomy in patients with a pathological margin ≥1 mm are similar to those following surgery in the general population. Endoscopic resection needs to be completed by surgery if pathological margins are less than 1 mm.

Abstract Objective To estimate the overall risk and the temporal trend of venous thromboembolism (VTE), deep vein thrombosis (DVT), and pulmonary embolism (PE) before and after gout diagnosis in an incident gout cohort compared with the general population. Methods We conducted a matched cohort study using a province-wide population-based administrative health database in Canada. We calculated incidence rates (IRs) and multivariable adjusted hazard ratios (HRs) for the risk of VTE, DVT and PE before and after gout diagnosis. Results Among 130 708 incident individuals with gout (64% male, mean age 59 years), 2071 developed VTE, 1377 developed DVT and 1012 developed PE. IRs per 1000 person-years for gout were 2.63, 1.74 and 1.28 compared with 2.03, 1.28 and 1.06 for non-gout, respectively. The fully adjusted HRs (95% CI) for VTE, DVT and PE were 1.22 (1.13, 1.32), 1.28 (1.17, 1.41) and 1.16 (1.05, 1.29). For the pre-gout period, the fully adjusted HRs (95% CI) were 1.51 (1.38, 1.64), 1.55 (1.40, 1.72) and 1.47 (1.31, 1.66) for VTE, DVT and PE. During the third, second and first years preceding gout, the fully adjusted HRs for VTE were 1.44, 1.56 and 1.62. During the first, second, third, fourth and fifth years after gout, the fully adjusted HRs were 1.63, 1.29, 1.33, 1.28 and 1.22. Similar trends were also seen for DVT and PE. Conclusion Increased risks of VTE, DVT and PE were found both before and after gout diagnosis. The risk increased gradually before gout, peaking in the year prior to diagnosis, and then progressively declined. Gout-associated inflammation may contribute to venous thrombosis risk.

Introduction:Many population-based studies identify surgical complications using hospital discharge abstract databases (DAD). With DAD, however, complications occurring after the discharge date cannot be followed up. This study used physician claims data to identify the complications of partial nephrectomy, and to compare the rates of complications of open, laparoscopic, and robot-assisted nephrectomies.Methods:Physician claims, DAD, and ambulatory care data from April 2003 to March 2016 were provided by Alberta Health. DAD and ambulatory care data were used to extract information on patients with kidney cancer who underwent partial nephrectomy. All physician claims within 30 days before and after surgery for the cohort were extracted. The numbers of the same International Classification of Diseases, Ninth Revision (ICD-9), codes before and after surgery were compared. If a number increased after surgery, this diagnosis was initially identified as a complication. All diagnoses with neoplasms were excluded. The incidence rates of complications for the three surgery groups were calculated. Chi-squared tests were conducted for the following nephrectomy comparisons: laparoscopic versus open; robot-assisted versus open; and robot-assisted versus laparoscopic.Results:A total of 1,890 kidney cancer patients had partial nephrectomies. Among them, 1,080, 411, and 399 had open, laparoscopic, and robot-assisted nephrectomies, respectively. One patient who had two different nephrectomies on the same day was excluded from analysis. The robot-assisted group had lower rates of digestive complications (ICD-9: 537–578, 787, 789, 998.6) and infections (ICD-9: 004–041, 998.5) than the open group, and higher rates of genitourinary complications (ICD-9: 584–599, 788, 997.5) than the laparoscopy group. The robot-assisted group had lower rates than the open group for most of the complication categories, but the differences were not statistically significant.Conclusions:Robot-assisted surgery appears to be superior to open surgery, but no better than laparoscopic surgery, in terms of minimizing the risk of complications following partial nephrectomy.

ObjectiveTo study the occurrence of ischaemic and haemorrhagic stroke in systemic lupus erythematosus (SLE) compared with the general population by age, sex and time since SLE diagnosisMethodsAdults with incident SLE were identified from the Swedish National Patient Register (NPR, n=3390) and general population comparators from the Total Population Register were matched on age, sex and county (n=16730). Individuals were followed prospectively until first of death, December 2013, emigration or incident stroke (identified from the NPR, Cause of Death Register and the Stroke Register). Incidence rates, rate differences and HR were estimated comparing SLE with non-SLE. Estimates were stratified by sex, age and time since diagnosis.ResultsWe observed 126 strokes in SLE and 304 in the general population. Individuals with SLE had a twofold increased rate of ischaemic stroke compared with the general population (HR 2.2; 95% CI 1.7 to 2.8). The HR for intracerebral haemorrhage was 1.4 (95% CI 0.7 to 2.8). There was effect modification by sex and age, with the highest HRs for females and individuals <50 years old. The HR for ischaemic stroke was highest in the first year of follow-up (3.7; 95% CI 2.1 to 6.5).ConclusionsThe relative risk of ischaemic stroke in SLE was more than doubled compared with the general population, and importantly, the highest relative risks were observed within the first year after SLE diagnosis. Thus, the first encounter with patients presents an opportunity for rheumatologists to screen for risk factors and intervene.

Abstract Background: The incidence of kidney diseases among bodybuilders is unknown. Methods: Between January 2011 and December 2019, the Iraqi Kurdistan 15 to 39 year old male population averaged 1,100,000 with approximately 24,000 regular and 56,000 total gymnasium participants. In that period, 15 participants had kidney biopsies. Annual age specific incidence rates (ASIR) with (95% confidence intervals) per 100,000 bodybuilders were compared with the general age-matched male population. Results: Among regular participants, diagnoses were: focal segmental glomerulosclerosis (FSGS), 2; membranous glomerulonephritis (MGN), 2; post-infectious glomeruonephritis (PIGN), 1; tubulointerstitial nephritis (TIN), 1; and nephrocalcinosis , 2. Acute tubular necrosis (ATN) was diagnosed in 2 newcomers and 5 regular participants. Anabolic steroids use was self-reported in 18%, protein powders in 71%, creatine in 29%, and veterinary grade vitamin D injections in 2.6% of regular participants. ASIR for FSGS, MGN, PIGN, and TIN among regular participants was not statistically different than the general population. ASIR of FSGS adjusted for anabolic steroid use was 5.1 (-0.2 to 12.3), a rate overlapping with FSGS in the general population at 2.0 (1.2 to 2.8). ATN presented with muscle pain and myoglobinuria among inexperienced bodybuilders and appeared secondary to exertional muscle injury. ASIR for ATN among total participants at 1.4 (0.4 to 2.4) was not considered significantly different than for the general population at 0.3 (0.1 to 0.5). Nephrocalcinosis was only diagnosed among bodybuilders at a 9-year cumulative rate of one per 314 vitamin D injectors. Conclusions: Kidney disease rates among bodybuilders was not significantly different than for the general population, except for nephrocalcinosis that was caused by injections of veterinary grade vitamin D compounds.

Abstract Background The prevalence of both atrial fibrillation (AF) and malignancies are increasing in the elderly, but incidences of new onset AF in different cancer subtypes are not well described.The objectives of this study were therefore to determine the incidence of AF in different cancer subtypes and to examine the association of cancer and future AF. Methods Using national databases, the Danish general population was followed from 2000 until 2012. Every individual aged > 18 years and with no history of cancer or AF prior to study start was included. Incidence rates of new onset AF were identified and incidence rate ratios (IRRs) of AF in cancer patients were calculated in an adjusted Poisson regression model. Results A total of 4,324,545 individuals were included in the study. Cancer was diagnosed in 316,040 patients. The median age of the cancer population was 67.0 year and 51.5% were females. Incidences of AF were increased in all subtypes of cancer. For overall cancer, the incidence was 17.4 per 1000 person years (PY) vs 3.7 per 1000 PY in the general population and the difference increased with age. The covariate adjusted IRR for AF in overall cancer was 1.46 (95% confidence interval (CI) 1.44–1.48). The strength of the association declined with time from cancer diagnosis (IRR0-90days = 3.41 (3.29–3.54), (IRR-180 days-1 year = 1.57 (CI 1.50–1.64) and (IRR2–5 years = 1.12 (CI 1.09–1.15). Conclusions In this nationwide cohort study we observed that all major cancer subtypes were associated with an increased incidence of AF. Further, cancer and AF might be independently associated.

Objective Data on the course of severe COVID-19 in inflammatory bowel disease (IBD) patients remains limited. We aimed to determine the incidence rate and clinical course of severe COVID-19 in the heavily affected South-Limburg region in the Netherlands. Methods All COVID-19 patients admitted to the only two hospitals covering the whole South-Limburg region between February 27, 2020 and January 4, 2021 were included. Incidence rates for hospitalization due to COVID-19 were determined for the IBD (n = 4980) and general population (n = 597,184) in South-Limburg. Results During a follow-up of 4254 and 510,120 person-years, 20 IBD patients (0.40%; 11 ulcerative colitis (UC), 9 Crohn’s disease (CD)) and 1425 (0.24%) patients from the general population were hospitalized due to proven COVID-19 corresponding to an incidence rate of 4.7 (95% Confidence interval (CI) 3.0–7.1) and 2.8 (95% CI 2.6–2.9) per 1000 patient years, respectively (Incidence rate ratio: 1.68, 95% CI 1.08–2.62, p = 0.019). Median age (IBD: 63.0 (IQR 58.0–75.8) years vs. general population: 72.0 (IQR 62.0–80.0) years, p = 0.10) and mean BMI (IBD: 24.4 (SD 3.3) kg/m2 vs. general population 24.1 (SD 4.9) kg/m2, p = 0.79) at admission were comparable in both populations. As for course of severe COVID-19, similar rates of ICU admission (IBD: 12.5% vs. general population: 15.7%, p = 1.00), mechanical ventilation (6.3% vs. 11.2%, p = 1.00) and death were observed (6.3% vs. 21.8%, p = 0.22). Conclusion We found a statistically significant higher rate of hospitalization due to COVID-19 in IBD patients in a population-based setting in a heavily impacted Dutch region. This finding reflects previous research that showed IBD patients using systemic medication were at an increased risk of serious infection. However, although at an increased risk of hospitalization, clinical course of severe COVID-19 was comparable to hospitalized patients without IBD.

Abstract Background Due to population aging, increasing prevalence of obesity and enhanced detection, the prevalence of atrial fibrillation (AF) worldwide is increasing steadily. Considerable sex differences in the epidemiology of AF such as lower prevalence and later onset in women compared to men have been reported. However, little is known about sex-specific temporal trends in AF incidence within the general population. Purpose To explore sex-specific age-adjusted secular trends in the incidence of AF in a general population from Norway between 1986 and 2014. Methods A total of 16,865 men and 15,413 women aged 20 years or older and without AF were enrolled in a longitudinal population study between 1986 and 2008 and followed up for incident AF to the end of 2014. Follow-up was from the date of attendance to the date of AF, emigration or death, whichever came first. All AF cases were validated by an independent endpoint committee using hospital and death records. AF incidence rates were calculated for each calendar year by dividing the number of AF cases per year by the corresponding person-time at risk. To allow for non-linear time trends, calendar year was fitted using fractional polynomials. Poisson regression was used to estimate calendar year-specific AF incidence rates adjusted for age. All analyses were stratified by sex. Results A total of 911 AF events in women and 1,139 AF events in men occurred over 324,090 person-years and 294,531 person-years of follow-up, respectively. During the study period AF incidence rates in men were at least double that in women (Figure). Age-adjusted AF incidence rates in women increased from 1986, peaked at 0.87 per 1000 person-years in 1998 and then decreased slightly towards 2014. In men AF incidence rates increased up to 2.18 per 1000 person-years in 2005 and then steeply decreased. Conclusion(s) AF incidence rates decreased in both women and men towards the end of the study period. The decrease was more profound in men compared to that in women. One possible explanation is more pronounced reduction in incidence and better treatment of myocardial infarction in men compared to women given that the aetiology of AF in men is mainly ischemic heart disease-related. However, further epidemiological analyses should be undertaken to identify explanatory factors. Funding Acknowledgement Type of funding source: Public hospital(s).

BackgroundVenous thromboembolism (VTE), including pulmonary embolism (PE) and deep venous thrombosis (DVT), can be life threatening. An increased frequency of VTE has been found in inflammatory conditions. To date, evidence assessing whether this risk is also greater in patients with ankylosing spondylitis (AS) is scarce.MethodsUsing the provincial British Columbia, Canada healthcare database that encompasses all residents within the province, we conducted matched cohort analyses of incident PE, DVT and overall VTE among incident cases of AS and compared them with individuals randomly selected from the general population without AS. We calculated incidence rates (IRs) of VTE and multivariable analyses after adjusting for traditional risk factors using Cox models.ResultsAmong 7190 incident cases of AS, 35 developed PE and 47 developed DVT. IRs of PE, DVT and overall VTE per 1000 person-years for patients with AS were 0.79, 1.06, 1.56 compared with 0.40, 0.50, 0.77 in the control cohort. Corresponding fully adjusted HRs (95% CI) of PE, DVT and VTE were 1.36 (0.92 to 1.99), 1.62 (1.16 to 2.26) and 1.53 (1.16 to 2.01), respectively. The risks of PE, DVT and VTE were highest in the first year of diagnosis with HR (95% CI) of 2.88 (0.87 to 9.62), 2.20 (0.80 to 6.03) and 2.10 (0.88 to 4.99), respectively.ConclusionsThese findings demonstrate an increased risk of VTE in the general AS population. This risk appears the most prominent in the first year after diagnosis.

448 Background: Cholangiocarcinoma (CCA) is a rare, lethal cancer with five-year survival of less than 10%. Although incidence rates have been increasing in the United States, ethnic variations in survival have not been investigated. We examined multi-ethnic variation in overall survival (OS) and CCA-specific survival (CSS) using data from the population-based Surveillance Epidemiology and End Results (SEER) program in the four year periods before and after introduction of gemcitabine/cisplatin as treatment for CCA. Methods: The study included data from 9,975 CCA cases reported in SEER between 2006 and 2013. Multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CIs) were calculated to examine overall and cholangiocarcinoma-specific survival by ethnicity, age, gender and in the pre- and post- gemcitabine/cisplatin era (2006-2009 vs. 2010-2013). Results: Compared to non-Hispanic Whites, Hispanics had poorer 3-year OS (HR = 1.18, 95% CI = 1.10-1.26) and 3-year CCA-specific survival (HR = 1.25, 95% CI = 1.16-1.35). Similarly, non-Hispanic Blacks had 3-year OS (HR = 1.22, 95% CI = 1.12-1.30) and 3-year CCA-specific survival (HR = 1.24, 95% CI = 1.13-1.37). Males and older patients also were found to have shorter survival compared to females and younger patients. Also noted was an increase in CCA incidence rate over time (2006-2013) of 5.93%. Among those < 50 versus ≥50 years old, a 23% higher rate of incidence in those < 50 was noted. Overall survival and CSS were both significantly improved for patients post-advent of Gemcitabine/Cisplatin. Statistically significant improvement in CSS pre- and post-advent of Gemcitabine/Cisplatin was noted in non-hispanic whites (p < 0.001) and Hispanics (p = 0.02). Conclusions: Hispanics and non-Hispanic Blacks have worse survival after diagnosis with CCA. Further studies are needed to determine the determinants of poor survival among these groups toward targeted intervention. Significant improvements in OS and CSS have been seen after the advent of Gemcitabine/Cisplatin. The incidence of CCA is rising faster in young persons, under the age of 50, compared with older patients.
