Investigating the relationships between unfavourable habitual sleep and metabolomic traits:evidence from multi-cohort multivariable regression and Mendelian randomization analyses

BACKGROUND: Sleep traits are associated with cardiometabolic disease risk, with evidence from Mendelian randomization (MR) suggesting that insomnia symptoms and shorter sleep duration increase coronary artery disease risk. We combined adjusted multivariable regression (AMV) and MR analyses of phenotypes of unfavourable sleep on 113 metabolomic traits to investigate possible biochemical mechanisms linking sleep to cardiovascular disease.METHODS: We used AMV (N = 17,368) combined with two-sample MR (N = 38,618) to examine effects of self-reported insomnia symptoms, total habitual sleep duration, and chronotype on 113 metabolomic traits. The AMV analyses were conducted on data from 10 cohorts of mostly Europeans, adjusted for age, sex, and body mass index. For the MR analyses, we used summary results from published European-ancestry genome-wide association studies of self-reported sleep traits and of nuclear magnetic resonance (NMR) serum metabolites. We used the inverse-variance weighted (IVW) method and complemented this with sensitivity analyses to assess MR assumptions.RESULTS: We found consistent evidence from AMV and MR analyses for associations of usual vs. sometimes/rare/never insomnia symptoms with lower citrate (- 0.08 standard deviation (SD)[95% confidence interval (CI) - 0.12, - 0.03] in AMV and - 0.03SD [- 0.07, - 0.003] in MR), higher glycoprotein acetyls (0.08SD [95% CI 0.03, 0.12] in AMV and 0.06SD [0.03, 0.10) in MR]), lower total very large HDL particles (- 0.04SD [- 0.08, 0.00] in AMV and - 0.05SD [- 0.09, - 0.02] in MR), and lower phospholipids in very large HDL particles (- 0.04SD [- 0.08, 0.002] in AMV and - 0.05SD [- 0.08, - 0.02] in MR). Longer total sleep duration associated with higher creatinine concentrations using both methods (0.02SD per 1 h [0.01, 0.03] in AMV and 0.15SD [0.02, 0.29] in MR) and with isoleucine in MR analyses (0.22SD [0.08, 0.35]). No consistent evidence was observed for effects of chronotype on metabolomic measures.CONCLUSIONS: Whilst our results suggested that unfavourable sleep traits may not cause widespread metabolic disruption, some notable effects were observed. The evidence for possible effects of insomnia symptoms on glycoprotein acetyls and citrate and longer total sleep duration on creatinine and isoleucine might explain some of the effects, found in MR analyses of these sleep traits on coronary heart disease, which warrant further investigation.</p

Cross-national comparative mixed-methods case study of recovery-focused mental health care planning and co-ordination: Collaborative Care Planning Project (COCAPP)

The care programme approach in England and care and treatment planning in Wales are systems designed to provide mental health service users with a named care co-ordinator who meets regularly with the service user, oversees their care and develops a written plan to guide the care that they receive. These approaches are meant to help people towards recovery. In this study, we investigated whether care is organised to help people’s recovery and whether this is done in a personalised way. We identified six NHS trust/health board sites in England and Wales, and surveyed staff and service users to measure views on recovery, empowerment and therapeutic relationships. At each site we also interviewed managers, clinical staff care co-ordinators, service users and carers about their experiences of care planning. We found that good relationships are important for service users, carers and care co-ordinators in care planning and supporting recovery. Experiences of care planning and co-ordination varied within all sites. People do not always feel involved in their own care. The understanding of recovery and personalisation varied among the service users and staff interviewed. Workers say that there is too much paperwork and, like service users, they rarely look at care plans once written. Staff focus on risk but this does not often appear to be discussed with people using services, which may be problematic. We recommend research to investigate new ways of working and training to increase staff contact time with service users and carers and to improve a focus on recovery

Care and communication between health professionals and patients affected by severe or chronic illness in community care settings: a qualitative study of care at the end of life

Background: Advance care planning (ACP) enables patients to consider, discuss and, if they wish, document their wishes and preferences for future care, including decisions to refuse treatment, in the event that they lose capacity to make decisions for themselves. ACP is a key component of UK health policy to improve the experience of death and dying for patients and their families. There is limited evidence about how patients and health professionals understand ACP, or when and how this is initiated. It is evident that many people find discussion of and planning for end of life care difficult, and tend to avoid the topic. Aim: To investigate how patients, their relatives and health professionals initiate and experience discussion of ACP and the outcomes of advance discussions in shaping care at the end of life. Design and data collection: Qualitative study with two workstreams: (1) interviews with 37 health professionals (general practitioners, specialist nurses and community nurses) about their experiences of ACP; and (2) longitudinal case studies of 21 patients with 6-month follow-up. Cases included a patient and, where possible, a nominated key relative and/or health professional as well as a review of medical records. Complete case triads were obtained for 11 patients. Four cases comprised the patient alone, where respondents were unable or unwilling to nominate either a family member or a professional carer they wished to include in the study. Patients were identified as likely to be within the last 6 months of life. Ninety-seven interviews were completed in total. Setting: General practices and community care settings in the East Midlands of England. Findings: The study found ACP to be uncommon and focused primarily on specific documented tasks involving decisions about preferred place of death and cardiopulmonary resuscitation, supporting earlier research. There was no evidence of ACP in nearly half (9 of 21) of patient cases. Professionals reported ACP discussions to be challenging. It was difficult to recognise when patients had entered the last year of life, or to identify their readiness to consider future planning. Patients often did not wish to do so before they had become gravely ill. Consequently, ACP discussions tended to be reactive, rather than pre-emptive, occurring in response to critical events or evidence of marked deterioration. ACP discussions intersected two parallel strands of planning: professional organisation and co-ordination of care; and the practical and emotional preparatory work that patients and families undertook to prepare themselves for death. Reference to ACP as a means of guiding decisions for patients who had lost capacity was rare. Conclusions: Advance care planning remains uncommon, is often limited to documentation of a few key decisions, is reported to be challenging by many health professionals, is not welcomed by a substantial number of patients and tends to be postponed until death is clearly imminent. Current implementation largely ignores the purpose of ACP as a means of extending personal autonomy in the event of lost capacity. Future work: Attention should be paid to public attitudes to death and dying (including those of culturally diverse and ethnic minority groups), place of death, resuscitation and the value of anticipatory planning. In addition the experiences and needs of two under-researched groups should be explored: the frail elderly, including those who manage complex comorbid conditions, unrecognised as vulnerable cases; and those patients affected by stigmatised conditions, such as substance abuse or serious mental illness who fail to engage constructively with services and are not recognised as suitable referrals for palliative and end of life care.

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Cardiovascular Health and Atrial Fibrillation or Flutter: A Cross-Sectional Study from ELSA-Brasil

Abstract Background The association between ideal cardiovascular health (ICVH) status and atrial fibrillation or flutter (AFF) diagnosis has been less studied compared to other cardiovascular diseases. Objective To analyze the association between AFF diagnosis and ICVH metrics and scores in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods This study analyzed data from 13,141 participants with complete data. Electrocardiographic tracings were coded according to the Minnesota Coding System, in a centralized reading center. ICVH metrics (diet, physical activity, body mass index, smoking, blood pressure, fasting plasma glucose, and total cholesterol) and scores were calculated as proposed by the American Heart Association. Crude and adjusted binary logistic regression models were built to analyze the association of ICVH metrics and scores with AFF diagnosis. Significance level was set at 0.05. Results The sample had a median age of 55 years and 54.4% were women. In adjusted models, ICVH scores were not significantly associated with prevalent AFF diagnosis (odds ratio [OR]:0.96; 95% confidence interval [95% CI]:0.80-1.16; p=0.70). Ideal blood pressure (OR:0.33; 95% CI:0.15–0.74; p=0.007) and total cholesterol (OR:1.88; 95% CI:1.19–2.98; p=0.007) profiles were significantly associated with AFF diagnosis. Conclusions No significant associations were identified between global ICVH scores and AFF diagnosis after multivariable adjustment in our analyses, at least partially due to the antagonistic associations of AFF with blood pressure and total cholesterol ICVH metrics. Our results suggest that estimating the prevention of AFF burden using global ICVH scores may not be adequate, and ICVH metrics should be considered in separate
