AbstractBackgroundFatigue syndromes (FSs) affect large numbers of individuals, yet evidence from epidemiological studies on adverse outcomes, such as premature death, is limited.MethodsCohort study involving 385 general practices in England that contributed to the Clinical Practice Research Datalink (CPRD) with linked inpatient Hospital Episode Statistics (HES) and Office for National Statistics (ONS) cause of death information. A total of 10 477 patients aged 15 years and above, diagnosed with a FS during 2000–2014, were individually matched with up to 20 comparator patients without a history of having a FS. Prevalence ratios (PRs) were estimated to compare the FS and comparison cohorts on clinical characteristics. Adjusted hazard ratios (HRs) for subsequent adverse outcomes were estimated from stratified Cox regression models.ResultsAmong patients diagnosed with FSs, we found elevated baseline prevalence of: any psychiatric illness (PR 1.77; 95% CI 1.72–1.82), anxiety disorders (PR 1.92; 1.85–1.99), depression (PR 1.89; 1.83–1.96), psychotropic prescriptions (PR 1.68; 1.64–1.72) and comorbid physical illness (PR 1.28; 1.23–1.32). We found no significant differences in risks for: all-cause mortality (HR 0.99; 0.91–1.09), natural death (HR 0.99; 0.90–1.09), unnatural death (HR 1.00; 0.59–1.72) or suicide (HR 1.68; 0.78–3.63). We did, however, observe a significantly elevated non-fatal self-harm risk: HR 1.83; 1.56–2.15.ConclusionsThe absence of elevated premature mortality risk is reassuring. The raised prevalence of mental illness and increased non-fatal self-harm risk indicate a need for enhanced assessment and management of psychopathology associated with fatigue syndromes.

Studies have suggested that moderate alcohol consumption is associated with a reduced risk of CVD and premature mortality in individuals with diabetes mellitus. However, history of alcohol consumption has hardly been taken into account. We investigated the association between current alcohol consumption and mortality in men and women with diabetes mellitus accounting for past alcohol consumption. Within the European Prospective Investigation into Cancer and Nutrition (EPIC), a cohort was defined of 4797 participants with a confirmed diagnosis of diabetes mellitus. Men and women were assigned to categories of baseline and past alcohol consumption. Hazard ratios (HR) and 95 % CI for total mortality were estimated with multivariable Cox regression models, using light alcohol consumption (>0–6 g/d) as the reference category. Compared with light alcohol consumption, no relationship was observed between consumption of 6 g/d or more and total mortality. HR for >6–12 g/d was 0·89 (95 % CI 0·61, 1·30) in men and 0·86 (95 % CI 0·46, 1·60) in women. Adjustment for past alcohol consumption did not change the estimates substantially. In individuals who at baseline reported abstaining from alcohol, mortality rates were increased relative to light consumers: HR was 1·52 (95 % CI 0·99, 2·35) in men and 1·81 (95 % CI 1·04, 3·17) in women. The present study in diabetic individuals showed no association between current alcohol consumption >6 g/d and mortality risk compared with light consumption. The increased mortality risk among non-consumers appeared to be affected by their past alcohol consumption rather than their current abstinence.

Introduction Atrial fibrillation (AF) is associated with dementia. Anticoagulation may modify this relationship, but it is unclear if this is due to stroke reduction alone. Methods Age- and sex-matched individuals from the U.K. Clinical Practice Research Datalink (2008–2016) with and without an incident diagnosis of AF were followed for a new dementia diagnosis. We estimated adjusted hazard ratios (aHRs) for incident dementia diagnosis in the AF cohort, overall and stratified by anticoagulation status, using the matched non-AF cohorts as reference. We performed a sensitivity analysis excluding individuals with stroke/transient ischaemic attack (TIA) before the observation period. Results Over 193,082 person-years (mean follow-up 25.7 ± 0.1 months), 347/15,276 AF (2.3%) and 1,085/76,096 non-AF (1.4%) were newly diagnosed with dementia (aHR, 1.31, 95% confidence interval, 1.15–1.49). The AF group had more co-morbidity and higher rates of dementia, both with and without anticoagulation, than non-AF. When those with history of stroke/ TIA before the observation period were excluded and those with incident stroke/TIA during the observation period were censored, AF individuals not on anticoagulation had significantly higher rates of dementia compared with non-AF, aHR 1.30 (1.06–1.58). Conclusion Our findings support the hypothesis that AF is a distinct risk factor for dementia, independent of stroke/TIA and other vascular risk factors. In those without stroke/TIA, risk of dementia is increased only in those who are not on anticoagulation, suggesting anticoagulation is protective presumably through reduction of sub-clinical embolic events. Further prospective research is needed to better ascertain the role of anticoagulation amongst targeted therapeutic strategies to reduce cognitive decline in AF.

Abstract Background Although bariatric surgery has been shown to reduce weight loss and obesity-related conditions, an improvement in depression remains unclear. The aim of this study was to determine whether bariatric surgery is associated with a resolution of depression, and the prevention of its onset. Method Patients with a BMI ≥ 30 kg/m2 who had undergone bariatric surgery were identified from the Clinical Practice Research Datalink (CPRD), matched 5:1 to controls. Cox regression analysis was used to determine the risk of developing de novo depression. Kaplan-Meier analysis compared the proportion of patients with no further consultations related to depression between the two groups. Results In total, 3534 patients who underwent surgery, of which 2018 (57%) had pre-existing depression, were matched to 15,480 controls. Cox proportional hazard modelling demonstrated surgery was associated with a HR of 1.50 (95% CI 1.32–1.71, p < 0.005) for developing de novo depression. For those with pre-existing depression, by 5 years, just over 20% of post-surgical patients had no further depression episodes compared with 17% of controls. Conclusion In individuals with a history of depression, bariatric surgery is associated with an improvement in mental health. On the contrary, the finding of increased de novo diagnoses of depression following surgery indicates the need for further study of the mechanisms by which bariatric surgery is associated with depression in this subset of patients.

Cardiac Troponins

Abstract Aims Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. To assess the factors associated with cTn testing in routine clinical practice and to evaluate the association of elevated levels of cTn with adverse outcomes in a large contemporary cohort of European AF patients. Methods and results Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into three groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), and (iii) cTn elevated (&gt;99th percentile). The composite outcome of any thromboembolism/any acute coronary syndrome (ACS)/cardiovascular (CV) death, defined as major adverse cardiovascular events (MACE) and all-cause death were the main endpoints. 10 445 (94.1%) AF patients were included in this analysis [median age 71 years, interquartile range (IQR): 63–77; males 59.7%]. cTn were tested in 2834 (27.1%). Overall, cTn was elevated in 904 (8.7%) and in-range in 1930 (18.5%) patients. Patients in whom cTn was tested tended to be younger (P &lt; 0.001) and more frequently presenting with first detected AF and atypical AF-related symptoms (i.e. chest pain, dyspnoea, or syncope) (P &lt; 0.001). On multivariable logistic regression analysis, female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease (CAD), and atypical AF symptoms were independently associated with cTn testing. After a median follow-up of 730 days (IQR: 692–749), 957 (9.7%) composite endpoints occurred while all-cause death was 9.5%. Kaplan–Meier analysis showed a higher cumulative risk for both outcomes in patients with elevated cTn levels (Figure) (Log Rank tests, P &lt; 0.001). On adjusted Cox regression analysis, elevated levels of cTn were independently associated with a higher risk for MACE [hazard ratio (HR): 1.74, 95% confidence interval (CI): 1.40–2.16] and all-cause death (HR 1.45, 95% CI: 1.21–1.74). Elevated levels of cTn were independently associated with a higher occurrence of MACE, all-cause death, any ACS, CV death and hospital readmission even after the exclusion of patients with history of CAD, diagnosis of ACS at discharge, those who underwent coronary revascularization during the admission and/or who were treated with oral anticoagulants plus antiplatelet therapy. Conclusions Elevated cTn levels were independently associated with an increased risk of all-cause mortality and adverse CV events, even after exclusion of CAD patients. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing.

Abstract Background The degree to which suicide risk aggregates in US families is unknown. The authors aimed to determine the familial risk of suicide in Utah, and tested whether familial risk varies based on the characteristics of the suicides and their relatives. Methods A population-based sample of 12 160 suicides from 1904 to 2014 were identified from the Utah Population Database and matched 1:5 to controls based on sex and age using at-risk sampling. All first through third- and fifth-degree relatives of suicide probands and controls were identified (N = 13 480 122). The familial risk of suicide was estimated based on hazard ratios (HR) from an unsupervised Cox regression model in a unified framework. Moderation by sex of the proband or relative and age of the proband at time of suicide (<25 v. ⩾25 years) was examined. Results Significantly elevated HRs were observed in first- (HR 3.45; 95% CI 3.12–3.82) through fifth-degree relatives (HR 1.07; 95% CI 1.02–1.12) of suicide probands. Among first-degree relatives of female suicide probands, the HR of suicide was 6.99 (95% CI 3.99–12.25) in mothers, 6.39 in sisters (95% CI 3.78–10.82), and 5.65 (95% CI 3.38–9.44) in daughters. The HR in first-degree relatives of suicide probands under 25 years at death was 4.29 (95% CI 3.49–5.26). Conclusions Elevated familial suicide risk in relatives of female and younger suicide probands suggests that there are unique risk groups to which prevention efforts should be directed – namely suicidal young adults and women with a strong family history of suicide.

Using Data

The relative toxicity of anxiolytic and hypnotic drugs commonly used for self-poisoning was assessed using data on suicides, prescriptions and non-fatal self-poisonings in England, 2005–2012. Data on suicide by self-poisoning were obtained from the Office for National Statistics, information on intentional non-fatal self-poisoning was derived from the Multicentre Study of Self-harm in England and data on prescriptions in general practice from the Clinical Practice Research Datalink. We used two indices of relative toxicity: fatal toxicity (the number of fatal self-poisonings relative to the number of individuals prescribed each drug) and case fatality (the number of fatal relative to non-fatal self-poisonings). Diazepam was the reference drug in all analyses. Temazepam was 10 times (95% confidence interval 5.48–18.99) and zopiclone/zolpidem nine times (95% confidence interval 5.01–16.65) more toxic in overdose than diazepam (fatal-toxicity index). Temazepam and zopiclone/zolpidem were 13 (95% confidence interval 6.97–24.41) and 12 (95% confidence interval 6.62–22.17) times more toxic than diazepam, respectively (case-fatality index). Differences in alcohol involvement between the drugs were unlikely to account for the findings. Overdoses of temazepam and zopiclone/zolpidem are considerably more likely to result in death than overdoses of diazepam. Practitioners need to exercise caution when prescribing these drugs, especially for individuals who may be at risk of self-harm, and also consider non-pharmacological options.

Background: While some professional societies recommend target-driven blood glucose (BG) control for all hospitalized patients, the association between elevated BG and adverse outcomes has not been well established in patients hospitalized with heart failure (HF). Methods: We evaluated a nationally representative cohort of 50,532 patients hospitalized with HF between 04/1998 – 06/2001. Admission BG was analyzed as a categorical variable (≤110, >110 –140, >140 –170, >170 –200, >200 mg/dL), and in 10 mg/dL increments. The association between BG and all-cause mortality over 30 days and 1 year was analyzed using Cox regression, both in the entire cohort and in patients with and without diabetes (DM). Results: After multivariable adjustment, there was no significant relationship between BG and 30-day mortality (for BG >110 to 140, >140 to 170, >170 to 200, and >200, hazard ratios and 95% confidence intervals were: 1.09 (0.98 –1.22), 1.27 (1.11–1.45), 1.16 (0.98–1.37), 1.00 (0.87–1.15) respectively vs. BG ≤110, P for linear trend 0.53). Results were similar for 1-year mortality, and did not differ between patients with and without DM (P values for DM*BG interaction 0.11 and 0.55 for 30-day and 1-year mortality respectively). A lack of association between BG and mortality over 30-days and 1-year was also observed when BG was analyzed in 10mg/dL increments (Figure ). Conclusions: We found no significant association between BG and mortality in a large cohort of hospitalized HF patients. While the impact of BG lowering on outcomes cannot be determined based on this study, our findings do not support resource-intensive interventions for BG monitoring and management in this patient group.

Background: Obesity is an independent risk factor for stroke. Weight gain has been associated with a higher risk of cardiovascular diseases in postmenopausal women. It is unclear, however, if weight changes before menopause have similar effects. We hypothesized that clinically meaningful premenopausal weight gain, defined as Body Mass Index (BMI) change >5%, would be associated with a higher stroke risk later in life. Methods: Using data from the California Teachers Study, we identified women aged < 55 with no history of stroke. We used weight changes between 1995-2006 as proxy for premenopausal weight gain. We defined weight change as modest or moderate using BMI changes of 5-10% and >10% respectively. Stroke outcomes were obtained from linkage to California hospitalization records. We used Cox regression models to calculate hazard ratios with 95% confidence intervals for the association of weight change and future stroke, adjusting for vascular risk factors. Results: Of 17,295 women included in the study, 113 had a stroke. In comparison to women who maintained a stable weight, women with moderate weight gain during premenopausal years had 2.0 times the risk of stroke. In the adjusted analysis, women with moderate weight gain had 89.6% higher risk of stroke, compared to the reference group. We found no significant association with stroke in women who had modest weight changes. Conclusion: Moderate premenopausal weight gain significantly increased stroke risk in women. Younger women should be educated about the effects of weight gain on future brain health. Count: 1836/1950

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Dutch Heart Foundation Background Screening for atrial fibrillation (AF) improves detection of AF. However, it is unknown whether AF detected at screening carries risks similar to clinically detected AF, and if it should be treated similarly. Purpose We aimed to compare clinical outcomes in individuals with screen-detected vs. hospital-detected incident AF. Methods We studied 8265 individuals (mean age 49 ± 13 years, 50% women) without prevalent AF from the population-based PREVEND (Prevention of Renal and Vascular End-Stage Disease) cohort study. By design, 70% of PREVEND participants had urinary albumin concentration ≥10 mg/l. AF was considered screen-detected when first detected on a 12-lead electrocardiogram (ECG) during one of the PREVEND study visits, and hospital-detected when first detected on a hospital ECG. Using Cox regression models with screen-detected and hospital-detected AF as time-varying covariates, we studied the association of screen-detected vs. hospital-detected AF with mortality, incident heart failure (HF), and incident cardiovascular (CV) events. Results During a mean follow-up of 9.7 years, 265 participants (3.2%) developed incident AF (mean age 62 ± 9 years, 30% women, 65% hypertension, 23% obesity, 9% diabetes, 15% history of myocardial infarction, 3% history of stroke, 2% prevalent HF). Of all incident AF cases, 60 (23%) were screen-detected and 205 (77%) hospital-detected. Baseline characteristics were generally comparable between participants with screen-detected and hospital-detected AF. A larger proportion of incident AF was screen-detected in men (26%) compared to women (15%). In univariabe analysis, both screen-detected and hospital-detected AF were strongly associated with death, incident HF, and incident CV events. After multivariable adjustment, hospital-detected AF was significantly associated with death (HR 2.95, 95% CI 2.18-4.00), incident HF (HR 3.98, 95% CI 2.49-6.34), and incident CV events (HR 1.92, 95% CI 1.21-3.06). Screen-detected AF was significantly associated with death (HR 2.21, 95% CI 1.09-4.47) and incident HF (HR 4.90, 95% CI 2.28-10.57), but not with incident CV events (HR 1.12, 95% CI 0.46-2.71). Conclusions In a population-based cohort enriched for microalbuminuria, almost a quarter of incident AF cases was first detected through ECG screening. Compared to hospital-detected AF, screen-detected AF was similarly associated with adverse outcomes. Although randomised trials are needed, this study highlights that AF screening may help decrease the general burden of CV disease.
