222Long-term mortality after early famine exposure: findings from the China Kadoorie Biobank

Background Previous studies suggested that increased risks of chronic diseases in China might be attributable to early experience of the Chinese Great Famine during last century, but the reliable evidence for adult mortality was rare. This study is to investigate the association of early famine exposure with death risks in the middle age. Methods A number of 94 051 participants from China Kadoorie Biobank were categorized as non-famine births (born between 10/1/1956 and 9/30/1958, and 10/1/1962 and 9/30/1964) and famine births (born between 10/1/1959 and 9/30/1961). The outcomes were total and cause specific mortality. Cox regression was used to estimate hazard ratio (HR) for famine exposure. Results During a median 10.2 years of follow-up, we documented 2802 total deaths in all participants. Prenatal famine exposure was only associated with the risks of ischemic heart disease (IHD) mortality in adulthood (310 deaths, HR [95% CI]: 1.34 [1.02, 1.75]), compared with non-famine births. We also observed the association of famine with total mortality (HR [95% CI]: 1.42 [1.12, 1.78]) in daily alcohol drinkers, but not in non-daily drinkers (P for interaction: 0.025). Conclusions This study indicated that early famine exposure was associated with an increased death risk of heart disease and such risk may be modified by adult alcohol consumption. Key messages Early Chinese famine experience might impact adult IHD deaths. Coexistence of early famine experience and adult alcohol consumption was associated with higher risks of total mortality.

Risk of solid cancers overall and by subtypes in patients with psoriatic arthritis treated with TNF inhibitors – a Nordic cohort study

Objectives To investigate whether TNF inhibitors (TNFi) are associated with increased risk of solid cancer in patients with psoriatic arthritis (PsA). Methods From the Nordic clinical rheumatology registers (CRR) here: SRQ/ARTIS (Sweden), DANBIO (Denmark), NOR-DMARD (Norway), ROB-FIN (Finland) and ICEBIO (Iceland) we identified PsA patients who started a first TNFi 2001–2017 (n = 9655). We identified patients with PsA not treated with biologics from (i) the CRR (n = 14 809) and (ii) the national patient registers (PR, n = 31 350). By linkage to the national cancer registers, we collected information on incident solid cancer overall and for eight cancer types. We used Cox regression to estimate hazard ratio (HR) with 95% CI of cancer (per country and pooled) in TNFi-exposed vs biologics-naïve, adjusting for age, sex, calendar period, comorbidities and disease activity. We also assessed standardized incidence ratios (SIR) in TNFi-exposed PsA vs the general population (GP). Results We identified 296 solid cancers among the TNFi-exposed PsA patients (55 850 person-years); the pooled adjusted HR for solid cancer overall was 1.0 (0.9–1.2) for TNFi-exposed vs biologics-naïve PsA from the CRR, and 0.8 (0.7–1.0) vs biologics-naïve PsA from the PRs. There were no significantly increased risks for any of the cancer types under study. The pooled SIR of solid cancer overall in TNFi treated PsA vs GP was 1.0 (0.9–1.1). Conclusion In this large cohort study from five Nordic countries, we found no increased risk of solid cancer in TNFi-treated PsA patients, neither for solid cancer overall nor for eight common cancer types.

Sex Differences in Early Cardiovascular and All-Cause Hospitalization Outcomes After Surviving Firearm Injury

The majority of the burden of firearm injury in the United States is on men as compared to women. There is limited evidence regarding sex differences in short-term hospitalization outcomes after surviving firearm injury. The risk of cardiovascular and all-cause hospital readmission, length of stay (LOS), and costs within 180 days after surviving an index firearm injury was compared between males and females. A claims-based, retrospective, cohort study was performed using Nationwide Readmission Database (2013–2014) to obtain a cohort of patients who survived an index hospitalization of firearm injury. The analysis was performed in August 2017. Cox proportional hazard regression models were used to estimate hazard ratio (HR) and 95% confidence intervals (95% CIs). Among 17,594 males and 2,289 females discharged alive after index firearm injury hospitalization, 14.4% and 13.2% were readmitted within 180 days. Within 180 days, the risk of cardiovascular readmission was 3.3 times greater among males versus females (HR = 3.34, 95% CI [1.18, 9.44]. Risk of all-cause readmission among males was greater at 90 days (HR = 1.40, 95% CI [1.04, 1.87]. Patients surviving a firearm injury have a substantial risk of subsequent hospitalizations. Cardiovascular readmissions are greater among males than females during the first 6 months after injury and may be indicative of a continuing long-term risk of health and patient outcomes that contributes to the overall burden of firearm injury.

Obstructive Sleep Apnea Patients Having Surgery Are Less Associated with Glaucoma

Objective.To investigate if different treatment strategy of obstructive sleep apnea (OSA) was associated glaucoma risk in Taiwanese population.Methods.Population-based retrospective cohort study was conducted using data sourced from the Longitudinal Health Insurance Database 2000. We included 2528 OSA patients and randomly selected and matched 10112 subjects without OSA as the control cohort. The risk of glaucoma in OSA patients was investigated based on the managements of OSA (without treatment, with surgery, with continuous positive airway pressure (CPAP) treatment, and with multiple modalities). The multivariable Cox regression was used to estimate hazard ratio (HR) after adjusting for sex, age, hypertension, diabetes, hyperlipidemia, and coronary artery disease.Results.The adjusted HR of glaucoma for OSA patients was 1.88 (95% CI: 1.46–2.42), compared with controls. For patients without treatment, the adjusted HR was 2.15 (95% CI: 1.60–2.88). For patients with treatments, the adjusted HRs of glaucoma were not significantly different from controls, except for those with CPAP (adjusted HR = 1.65, 95% CI = 1.09–2.49).Conclusions.OSA is associated with an increased risk of glaucoma. However, surgery reduces slightly the glaucoma hazard for OSA patients.
