Abstract There is evidence that certain infections and autoimmunity predispose to the development of non-Hodgkin lymphomas (NHLs). A previous study reported that hospitalization for infections in infancy led to an increased risk of NHL. By using population-based registries in Sweden, we compared the rate of hospitalization for infections in infancy between lymphoma cases and matched controls for patients born since 1964. A history of infection was associated with a significantly increased risk of aggressive B-cell lymphomas (odds ratio 2.1, 95% confidence interval 1.11-4.04, P = .02). The specific infections involved were respiratory and intestinal. No effects were observed among cases of Hodgkin lymphoma. This association could result from the infection, its treatment, or could be a surrogate marker for underlying immune defects. Further studies are needed to determine whether this association is present among NHL occurring in older adults and if improved survival of patients with immune defects has contributed to the secular increases in incidence of NHLs.

Background and Purpose: Approximately 8% of Blacks have sickle cell trait (SCT), and there are conflicting reports from recent cohort studies on the association of SCT with ischemic stroke (IS). Most prior studies focused on older populations, with few data available in young adults. Methods: A population-based case-control study of early-onset IS was conducted in the Baltimore-Washington region between 1992 and 2007. From this study, 342 Black IS cases, ages 15 to 49, and 333 controls without IS were used to examine the association between SCT and IS. Each participant’s SCT status was established by genotyping and imputation. For analysis, χ 2 tests and logistic regression models were performed with adjustment for potential confounding variables. Results: Participants with SCT (n=55) did not differ from those without SCT (n=620) in prevalence of hypertension, previous myocardial infarction, diabetes mellitus, and current smoking status. Stroke cases had increased prevalence in these risk factors compared with controls. We did not find an association between SCT and early-onset IS in our overall population (odds ratio=0.9 [95% CI, 0.5–1.7]) or stratified by sex in males (odds ratio=1.26 [95% CI, 0.56–2.80]) and females (odds ratio=0.67 [95% CI, 0.28–1.69]). Conclusions: Our data did not find evidence of increased risk of early-onset stroke with SCT.

ObjectiveTo assess the role of four biomarkers of neuroendocrine activation and endothelial dysfunction in the longitudinal prediction of fragility fractures.MethodsWe analysed a population-based prospective cohort of 5415 community-dwelling individuals (mean age, 68.9±6.2 years) enrolled in the Malmö Preventive Project followed during 8.1±2.9 years, and investigated the longitudinal association between C-terminal pro-arginine vasopressin (CT-proAVP), C-terminal endothelin-1 precursor fragment (CT-proET-1), the mid-regional fragments of pro-adrenomedullin (MR-proADM) and pro-atrial natriuretic peptide (MR-proANP), and incident vertebral, pelvic and extremity fractures.ResultsOverall, 1030 (19.0%) individuals suffered vertebral, pelvic or extremity fracture. They were older (70.7±5.8 vs 68.4±6.3 years), more likely women (46.9% vs 26.3%), had lower body mass index and diastolic blood pressure, were more often on antihypertensive treatment (44.1% vs 38.4%) and had more frequently history of fracture (16.3% vs 8.1%). Higher levels of MR-proADM (adjusted HR (aHR) per 1 SD: 1.51, 95% CI 1.01 to 2.28, p<0.001) and MR-proANP (aHR: 1.23, 95% CI 1.05 to 1.45, p<0.001) were independently associated with increased risk of any fracture. The fracture risk increased linearly across MR-proANP quartiles. Individuals who were in the top quartile of all four biomarkers had a significant higher risk of fracture at any site (aHR: 2.32, 95% CI 1.86 to 2.91), vertebral fracture (aHR: 3.16, 95% CI 1.97 to 5.07) and femoral fracture (aHR: 2.35, 95% CI 1.64 to 3.36).ConclusionsElevated levels of MR-proADM and MR-proANP independently predict fragility fractures in older adults. In subjects with top quartile levels of all four biomarkers there is a twofold to threefold increase in risk of vertebral and femoral fractures.

Background: Following the outbreak of SARS-COV2 > 7,750,000 Americans were diagnosed with COVID-19. Many comorbidities were found to be associated with increased risk of severe disease. Due to limited testing and high percent of asymptomatic cases the exact prevalence is unclear. Moreover, whether the presence of comorbidities is associated with an increased rate of COVID-19 remains unknown. Methods: COVID-19 Community Research Partnership (CCRP) is a prospective cohort designed to collect information about the community's coronavirus exposures, symptoms, and prevalence (NCT04342884). Serological substudy is a prospective case series evaluating development of IgM or IgG in randomly selected 5000 participants from the CCRP cohort. Serological test kits are shipped to the volunteers monthly. Prevalence of comorbidities was estimated using electronic health records. Results: There were 4902 patients included in the analysis (Figure). Of those, 2,832 (57.8%) were female, mean age±SD was 49.6±14.4. There were 3,871 (79%) Caucasians, 422 (8.6%) - African Americans and 242 (4.9%) - Hispanics (Table). From May 2020 to August 2020, 424 patients (8.7%) seroconverted (IgM or IgG positive): 327 (6.7%) were found to be IgM positive/ IgG negative, 38 (0.8%)- IgM negative/IgG positive and 59 (1.2%) - IgM positive/ IgG positive. Prevalence of comorbidities was low: 1,318 (26.9%) patients have hypertension, 1,379 (28.1%)- hyperlipidemia, 413 (8.4%)- diabetes, 217 (4.4%)- coronary artery disease, 156 (3.2%)- peripheral arterial disease, 132 (2.7%)- atrial fibrillation, 95 (1.9%)- history of deep venous thrombosis and pulmonary embolism, and 54 (1.1%)- history of heart failure (HF). Only the presence of HF was associated with an increased odds ratio of seroconversion OR 2.4, (1.21- 4.87), p<0.012. This association remained robust after controlling for age, sex and race. Conclusion: Prevalence of seroconversion was near 9%. Presence of heart failure was independently associated with an increased odds ratio of seroconversion.

ABSTRACTObjectiveTo estimate the incidence and risk factors for injuries among older adults with and without dementia.MethodsA retrospective, population-based cohort study was undertaken using the Western Australian Data Linkage System (WADLS). Cases included 29,671 (47.9%) older adults with an index hospital admission for dementia, aged 50+ years between 2001 and 2011. Comparison participants without dementia included a random sample of 32,277 (52.1%) older adults aged 50+ years from the State Electoral Roll. The outcome of interest was a hospital admission to a metropolitan tertiary hospital in Perth Western Australia for at least 24 hours with an injury as the principal diagnosis. Descriptive statistics were used to compare participants with and without dementia in terms of socio-demographic characteristics, co-morbid conditions, injury severity, cause of injury and length of stay in hospital. Population rates were calculated based on the relevant WA population data from the Australian Bureau of Statistics. Poisson regression with robust standard errors was used to examine risk factors for injuries in those with and without dementia, after adjusting for relevant confounders. ResultsThe age-standardised injury rates for older adults (60+ years) were 117 per 1,000 population with dementia and 24 per 1,000 population without dementia. The majority of injuries were caused by falls for both the dementia (94%) and non-dementia (87%) groups followed by transport-related injuries and burns. The results of the multivariable modelling found that older adults with a diagnosis of dementia had over double the risk of hospital admission for an injury compared to those without dementia (IRR=2.05; 95% CI=1.96-2.15). Other significant predictors of an admission for all-cause injury were older adults aged 85+ years (IRR=1.43; 95% CI=1.13-1.81), being unmarried (IRR=1.07; 95% CI=1.03-1.12) and a history of falls (IRR=1.03; 95% CI=1.01-1.06). Females were at reduced risk of injury (IRR=0.92; 95% CI=0.87-0.97).ConclusionsOlder adults with dementia were at increased risk of an admission for an injury compared to those without dementia. Multifactorial injury prevention programs should target older people with dementia, those over 85 years, living alone and with a history of previous falls.

Abstract Aims To analyse the association between coeliac disease (CD) and depression in children, adolescents, and young adults with type 1 diabetes (T1D). Methods We included 79,067 T1D patients aged 6–20 years, with at least six months of diabetes duration, and treatment data between 1995 and 2019 were documented in the diabetes patient follow-up registry. We categorized patients into four groups: T1D only (n = 73,699), T1 + CD (n = 3379), T1D + depression (n = 1877), or T1D + CD + depression (n = 112). Results CD and depression were significantly associated (adjusted OR: 1.25 [1.03–1.53]). Females were more frequent in both the depression and the CD group compared with the T1D only group. Insulin pumps were used more frequently in T1D + CD and T1D + depression compared with T1D only (both p < .001). HbA1c was higher in T1D + depression (9.0% [8.9–9.0]), T1D + CD + depression (8.9% [8.6–9.2]), both compared with T1D only (8.2% [8.2–8.2], all p < .001). We found comorbid autism, attention deficit hyperactivity disorder, anxiety, schizophrenia, and eating disorders more frequently in the T1D + CD + depression group compared with T1D only (all p < .001). Conclusions CD and depression are associated in young T1D patients. The double load of T1D and CD may lead to an increased risk for depression. Depression was associated with additional psychological and neurological comorbidities. Aside from imperative CD screening after T1D diagnosis and regular intervals, depression screening might be helpful in routine care, especially in patients with diagnosed CD.

Abstract Aims Pulse pressure (PP) is a well-known risk factor for cardiovascular disease. However, the association between the PP and dementia is not well identified. This study aimed to determine the effect of PP on the risk of dementia development in different age subgroups using a longitudinal, population-based, and stroke-free cohort from the general population. Methods The association of PP with the development of incident dementia was assessed from January 1, 2005, to December 31, 2013, in 433,154 participants without a history of dementia or stroke from the Korea National Health Insurance Service-Health Screening cohort. The diagnosis of dementia was defined using the 10th revision of the International Classification of Disease codes. Results The mean age of the cohort was 55.7±9.2 years, 45.7% were women. Hypertension was 23.6%. The mean systolic and diastolic blood pressure of the entire cohort were 125.9±16.6 and 78.4±10.7 mmHg, respectively. Mean PP was 47.5±10.9 mmHg. In the middle-age group (40 to 50 year-old), increasing of 10 mmHg of PP was associated with incident dementia after adjusting mean blood pressure and clinical variables with a hazard ratio (HR) of 1.21 (95% confidence interval [CI]: 1.19–1.23, p&lt;0.001). The association was still significant even after censoring for stroke (HR: 1.16, 95% CI: 1.08–1.22, p&lt;0.001). In the older population, elevation of PP was not associated with dementia development (HR: 0.98, 95% CI: 0.95–1.01, p=0.247) Conclusion PP was associated with increased risk of dementia only in middle-aged population beyond that of mean arterial pressure.

AbstractThe association between bullous pemphigoid (BP) and melanoma is yet to be investigated. We aimed to assess assess the bidirectional association between BP and melanoma and to delineate the epidemiological features of patients with both diagnoses. A population-based cohort study was performed comparing BP patients (n = 3924) with age-, sex- and ethnicity-matched control subjects (n = 19,280) with regard to incident cases of melanoma. A case–control design was additionally adopted to estimate the risk of BP in individuals with a preexisting diagnosis of melanoma. The prevalence of preexisting melanoma was higher in patients with BP than in control subjects (1.5% vs. 1.0%, respectively; P = 0.004). A history of melanoma confers a 50% increase in the risk of subsequent BP (OR 1.53; 95% CI 1.14–2.06). This risk was higher among males (OR 1.66; 95% CI 1.09–2.54) and individuals older than 80 years (OR 1.63; 95% CI 1.11–2.38), and persisted after adjustment for multiple putative confounders including PD-1/PDL-1 antagonists (adjusted OR 1.53; 95% CI 1.14–2.06). Conversely, the risk of melanoma among patients with BP was slightly elevated, but did not reach the level of statistical significance (adjusted HR 1.13; 95% CI 0.73–1.74). Patients with a dual diagnosis of BP and melanoma were older at the onset of BP and had lower body mass index. A history of melanoma is associated with a 50% increase in the incidence of subsequent BP. Physicians managing patients with both conditions should be aware of this association. Further research is warranted to reveal the underlying mechanism of these findings.

Abstract Sensory impairment (SI) is common among older adults, and it is an increasingly important public health challenge as the population ages. We evaluated the association between SI and incident disability-related cessation of employment in older adults using the population-based Health and Retirement Study. Participants employed in 2006 completed biennial interviews until self-reported incident disability-related cessation of employment. Participants were censored at loss to follow-up, retirement, or 2018. Participants rated their vision and hearing, using eyeglasses or hearing aids if applicable, on a Likert scale (poor, fair, good, very good, excellent). SI was defined as poor or fair ability, and SI was categorized as neither SI (NSI), vision impairment alone (VI), hearing impairment alone (HI), and dual SI (DSI). Cox proportional hazard regression assessed the association between SI and incident disability-related cessation of employment, adjusting for demographic and health covariates. Overall, 4726 participants were included: 421 (8.9%) were with VI, 487 (10.3) with HI, and 203 (4.3%) with DSI. Mean age was 61.0 ± 6.8 years, 2488 (52.6%) were women, and 918 (19.4) were non-White. In the fully adjusted model, incident disability-related cessation of employment over the 12-year follow-up period was higher in VI (Hazard Ratio (HR)=1.30, 95% confidence interval (CI)=0.92, 1.85), HI (HR=1.60, CI=1.16, 2.22), and DSI (HR=2.02, CI=1.38, 2.96). These findings indicate that employed older adults with SI are at increased risk of incident disability-related cessation of employment, and that older adults with DSI are particularly vulnerable. Addressing SI in older adults may lengthen their contribution to the workforce.
