197 Background: Patients with cancer have nearly twice the incidence of suicide compared to the general population(1). To date, identifying patients at risk for suicide remains challenging. The purpose of this study was to identify risk factors of suicide among patients with GI cancer. Methods: A retrospective analysis was completed using Surveillance, Epidemiology, and End Results data from 1973 to 2014. Comparisons with the general US population were based on US mortality data collected by the National Center for Health Statistics. Suicide incidence, rates and standardized mortality ratio (SMR) were obtained by SEER*Stat 8.3.4. Results: Among 711859 patients with GI cancer observed for 3373014 person-years, 1116 suicides were identified, for an adjusted suicide rate of 33.1/100,000 person-years (SMR 1.74 [95% CI 1.64-1.85]). The highest suicide risks (SR) were in esophageal (SMR 5.42 [95% CI 4.30-6.75]), pancreatic (SMR 4.91 [95% CI 3.83-6.19]) and liver or intrahepatic biliary cancer (SMR 3.36 [95% CI 2.35-4.65]). Higher SRs were associated with unmarried status, age 40 years and older at diagnosis and the first 5 years after diagnosis. In esophageal (EC) and pancreatic (PC) cancer, SR was 8 folds higher in unmarried patients compared to the general population with a SMR of 8.31 [95% CI 5.68-11.73] and 7.68 [95% CI 5.18-10.97], respectively. In EC and PC, SR was highest in patients > 80 years (SMR 7.09 [95% CI 3.40-13.03]) and 40-59 years at diagnosis (SMR 7.10 [95% CI 1.93-18.18]), respectively. Patients have especially high SR the first year after diagnosis in EC (SMR 10.25 [95% CI 7.65-13.44]) and PC (SMR 7.72 [95% CI 5.83-10.03]). Conclusions: While overall, patients with GI cancer have nearly twice the SR, those with certain cancer subtypes have up to 5 times the SR when compared to the general population. SRs are highest in esophageal, pancreatic and liver or intrahepatic biliary cancer. Suicide screening should especially target patients with EC and PC who are unmarried or lack a support system and within the first year after cancer diagnosis.

Patients At Risk

196 Background: Patients with cancer have nearly twice the incidence of suicide compared to the general population. To date, identifying patients at risk for suicide remains challenging. Colorectal cancer (CRC) is the third most common cancer in the US. The purpose of this study was to identify risk factors associated with higher suicide rates (SR) among patients with CRC. Methods: A retrospective analysis was completed using Surveillance, Epidemiology, and End Results data from 1973 to 2014. Comparisons with the general US population were based on US mortality data collected by the National Center for Health Statistics. Suicide incidence, rates and standardized mortality ratio (SMR) were obtained by SEER*Stat 8.3.4. Results: Among 414788 patients with CRC observed for 2785811 person-years, 747 suicides were identified, for an adjusted SR of 26.7/100,000 person-years (SMR 1.40 [95% CI 1.30-1.50]). Higher SRs were associated with male sex, non-white or non-black race, being unmarried and having advanced disease at diagnosis (Table 1). SR was highest in the first year after diagnosis (SMR 2.00 [95% CI 1.68-2.37]) and with increasing age at diagnosis among unmarried patients. In patients 60 to 64 years at diagnosis, SR was highest in unmarried men (SMR 3.72 [95% CI 2.61-5.15]) and lowest in married women (SMR 0.61 [95% CI 0.17-1.57]). Conclusions: CRC is one of the most common cancers in the US. Patients with CRC have a 1.5-fold increase in SR compared to the general population. Suicide screening should especially target those in their first year after diagnosis, particularly older, unmarried patients. [Table: see text]

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 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.

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.

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.

BackgroundGlobally, poisonings account for most medically-attended self-harm. Recent data on poisoning substances are lacking, but are needed to inform self-harm prevention.AimTo assess poisoning substance patterns and trends among 10–24-year-olds across EnglandDesign and settingOpen cohort study of 1 736 527 young people, using linked Clinical Practice Research Datalink, Hospital Episode Statistics, and Office for National Statistics mortality data, from 1998 to 2014.MethodPoisoning substances were identified by ICD-10 or Read Codes. Incidence rates and adjusted incidence rate ratios (aIRR) were calculated for poisoning substances by age, sex, index of multiple deprivation, and calendar year.ResultsIn total, 40 333 poisoning episodes were identified, with 57.8% specifying the substances involved. The most common substances were paracetamol (39.8%), alcohol (32.7%), non-steroidal anti-inflammatory drugs (NSAIDs) (11.6%), antidepressants (10.2%), and opioids (7.6%). Poisoning rates were highest at ages 16–18 years for females and 19–24 years for males. Opioid poisonings increased fivefold from 1998–2014 (females: aIRR 5.30, 95% confidence interval (CI) = 4.08 to 6.89; males: aIRR 5.11, 95% CI = 3.37 to 7.76), antidepressant poisonings three-to fourfold (females: aIRR 3.91, 95% CI = 3.18 to 4.80, males: aIRR 2.70, 95% CI = 2.04 to 3.58), aspirin/NSAID poisonings threefold (females: aIRR 2.84, 95% CI = 2.40 to 3.36, males: aIRR 2.76, 95% CI = 2.05 to 3.72) and paracetamol poisonings threefold in females (aIRR 2.87, 95% CI = 2.58 to 3.20). Across all substances poisoning incidence was higher in more disadvantaged groups, with the strongest gradient for opioid poisonings among males (aIRR 3.46, 95% CI = 2.24 to 5.36).ConclusionIt is important that GPs raise awareness with families of the substances young people use to self-harm, especially the common use of over-the-counter medications. Quantities of medication prescribed to young people at risk of self-harm and their families should be limited, particularly analgesics and antidepressants.

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.

6619 Background: Survivorship research after a breast cancer (BC) diagnosis has identified psychosocial, functional and comorbidity outcomes that adversely influence daily life. Little is known, however, about non-breast cancer (NBC) mortality after a BC diagnosis. Methods: This retrospective cohort study included Australian women aged 30–79 years diagnosed with BC between January 1982 and December 2004, with mortality examined from January 1993 to December 2005. The age-standardized mortality ratio (SMR) was used to compare NBC causes of death in the BC cohort and the age-matched Australian female population between January 1993 and December 2005. Results: The median follow-up time for the cohort of 159,550 Australian women diagnosed with BC was 7.04 years (range 0–24.7 years). During the follow-up period, 30,819 (19.3%) died of BC, 5,403 (3.4%) died of other cancers (OC), 18,349 (11.5%) died of non-cancer (NC) causes, while 104,979 (65.8%) were still alive at the end of the follow-up period. Excluding the first year after diagnosis, women with a prior BC diagnosis had a higher risk of mortality (SMR = 328.6.95% CI = 324.8–332.3, p < 0.001) than the age matched female population. NBC mortality risk was elevated for OC (SMR = 103.7, CI = 100.1–107.5, p = 0.022) but reduced for NC causes (SMR = 94.9, CI = 92.3–97.5, p < 0.001). For the age groupings 30–49 years (n = 46,736), 50–69 years (n = 82,967), and 70–79 years (n = 29,847), SMR's for NC causes were 168.2 (CI = 144.1–195.1, p < 0.001), 100.9 (CI = 95.9–106.1, p = 0.355), and 90.5 (CI = 87.5–93.5, p < 0.001) respectively. Following the first year of diagnosis, the SMR for OC was non-significantly elevated with time after diagnosis. In comparison, the SMR for NC causes reduced with time after diagnosis; SMR = 96.4 (CI = 92.1–100.8, p = 0.055) at 2–5 years after diagnosis, 98.2 (CI = 93.7–102.8, p = 0.222) at 6–10 years, 92.8 (CI = 87.2–98.7, p = 0.008) at 11–15 years and 82.2 (CI = 74.8–90.2, p < 0.001) at more than 15 years. Conclusions: BC survivors have a higher risk of mortality from OC compared to the aged-matched Australian female population, but a reduced risk from NC causes. Although NC mortality is lower in older women and as time from BC diagnosis increases, women less than 50 years have a higher risk of NC mortality.

Background: Chemotherapy is suspected to be a risk factor for stroke in patients with cancer, athough the results from large-scale studies are controversial. Few strategies are available for reducing the stroke-related risks.Methods: We analyzed stroke incidence rates in Taiwan’s Longitudinal Health Insurance database 2000 (LHID2000) for patients aged ≥20 years with newly-diagnosed cancer between Jan 1, 2000 and Dec 31, 2006, who did or did not receive chemotherapy. Moreover, we compared stroke incidence rates among chemotherapy users who did or did not use traditional Chinese medicine. All study participants were followed-up for 5 years or until they had a stroke.Results: In adjusted Kaplan-Meier analysis, the incidence of stroke was higher within the first year of cancer diagnosis among chemotherapy recipients compared with those who did not receive chemotherapy (31.1 vs. 9.75; adjusted subdistribution hazard ratio [sHR] 2.21; 95% confidence interval [CI], 1.52–3.20; p &lt; 0.001). This between-group difference persisted at 4 years of follow-up (13.6 vs. 5.42; adjusted sHR 1.94; 95% CI, 1.53–2.46; p &lt; 0.001). Similarly, the 5-year incidence rate of stroke was significantly lower among chemotherapy recipients using TCM vs. non-TCM users (0.19 vs. 0.46; adjusted sHR 0.45; 95% CI, 0.26–0.79; p &lt; 0.001), as was the mortality rate (adjusted sHR 0.55; 95% CI, 0.44–0.68; p &lt; 0.001).Conclusion: These Taiwanese data suggest that chemotherapy is a risk factor for stroke and that the use of TCM can significantly mitigate this risk. TCM also appears to reduce the mortality risk associated with chemotherapy.

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.
