The relationship between alcohol use and long-term cognitive decline in middle and late life: a longitudinal analysis using UK Biobank

Background Using UK Biobank data, this study sought to explain the causal relationship between alcohol intake and cognitive decline in middle and older aged populations. Methods Data from 13 342 men and women, aged between 40 and 73 years were used in regression analysis that tested the functional relationship and impact of alcohol on cognitive performance. Performance was measured using mean reaction time (RT) and intra-individual variation (IIV) in RT, collected in response to a perceptual matching task. Covariates included body mass index, physical activity, tobacco use, socioeconomic status, education and baseline cognitive function. Results A restricted cubic spline regression with three knots showed how the linear (β1 = −0.048, 95% CI: −0.105 to −0.030) and non-linear effects (β2 = 0.035, 95% CI: 0.007–0.059) of alcohol use on mean RT and IIV in RT (β1 = −0.055, 95% CI: −0.125 to −0.034; β2 = 0.034, 95% CI: 0.002–0.064) were significant adjusting for covariates. Cognitive function declined as alcohol use increased beyond 10 g/day. Decline was more apparent as age increased. Conclusions The relationship between alcohol use and cognitive function is non-linear. Consuming more than one UK standard unit of alcohol per day is detrimental to cognitive performance and is more pronounced in older populations

Tavistock Adult Depression Study (TADS): a randomised controlled trial of psychoanalytic psychotherapy for treatment-resistant/treatment-refractory forms of depression

ABSTRACT: BACKGROUND: Long-term forms of depression represent a significant mental health problem for which there is a lack of effective evidence-based treatment. This study aims to produce findings about the effectiveness of psychoanalytic psychotherapy in patients with treatment-resistant/treatment-refractory depression and to deepen the understanding of this complex form of depression. METHODS: INDEX GROUP: Patients with treatment resistant/treatment refractory depression. DEFINITION & INCLUSION CRITERIA: Current major depressive disorder, 2 years history of depression, a minimum of two failed treatment attempts, [greater than or equal to]14 on the HRSD or [greater than or equal to]21 on the BDI, plus complex personality and/or psycho-social difficulties. EXCLUSION CRITERIA: Moderate or severe learning disability, psychotic illness, bipolar disorder, substance dependency or receipt of test intervention in the previous two years. DESIGN: Pragmatic, randomised controlled trial with qualitative and clinical components. TEST INTERVENTION: 18 months of weekly psychoanalytic psychotherapy, manualised and fidelity-assessed using the Psychotherapy Process Q-Sort. CONTROL CONDITION: Treatment as usual, managed by the referring practitioner. RECRUITMENT: GP referrals from primary care. RCT MAIN OUTCOME: HRSD (with [less than or equal to]14 as remission). SECONDARY OUTCOMES: depression severity (BDI-II), degree of co-morbid disorders Axis-I and Axis-II (SCID-I and SCID-II-PQ), quality of life and functioning (GAF, CORE, Q-les-Q), object relations (PROQ2a), Cost-effectiveness analysis (CSRI and GP medical records). FOLLOW-UP: 2 years. Plus: a). Qualitative study of participants' and therapists' problem formulation, experience of treatment and of participation in trial. (b) Narrative data from semi-structured pre/post psychodynamic interviews to produce prototypes of responders and non-responders. (c) Clinical case-studies of sub-types of TRD and of change. DISCUSSION: TRD needs complex, long-term intervention and extended research follow-up for the proper evaluation of treatment outcome. This pushes at the limits of the design of randomised therapeutic trials,. We discuss some of the consequent problems and suggest how they may be mitigated. Trial registration Current Controlled Trials ISRCTN40586372

Barriers to cervical screening and interest in self-sampling among women who actively decline screening

Objectives: Understanding why some women actively decline cervical screening could contribute to tailored intervention development. We explored reasons for non-participation in cervical screening among women who had made an active decision not to attend in the future. We also explored interest in human papillomavirus self-sampling. // Methods: In a population-based survey of women in Great Britain, home-based computer-assisted interviews were carried out with screening eligible women. Women reported their intention to attend for screening when next invited. They endorsed predefined barriers to screening and indicated their interest in human papillomavirus self-sampling. // Results: Women who had actively declined screening and those who intended to go but were currently overdue (n=543) were included in this analysis. Women who had made an active decision not to be screened in the future were more likely to endorse the barriers ‘I have other more important things to worry about’ and to perceive screening to be of low relevance based on their sexual behaviour. Most participants (70%) indicated that they would be interested in human papillomavirus self-sampling. Interest in self-sampling was greater among those who reported having had a bad experience of screening in the past, were too busy or embarrassed to attend, or would not want a man to carry out the test. // Conclusions: Women who had made an active decision not to attend screening felt it was of low relevance to them and that they had more important things to worry about. Shifting the perceived cost–benefit ratio for these women by offering human papillomavirus self-sampling might increase screening participation in this group

Chemsex and the city: sexualised substance use in gay bisexual and other men who have sex with men attending sexual health clinics

The objective of this study was to analyse associations between sexualised substance use (chemsex), STI diagnoses and sexual behaviour among gay bisexual and other men who have sex with men accessing sexual health clinics to better inform clinical pathways. A retrospective case notes review was undertaken following the introduction of more detailed and holistic profomas for all gay bisexual and other men who have sex with men attending two London sexual health clinics between 1 June 2016 and 31 January 2015. Chemsex status was documented for 655/818. Overall, 30% disclosed recreational drug use of whom 113 (57%) disclosed chemsex and 27 (13.5%) injecting drugs. HIV-positive gay bisexual and other men who have sex with men were more likely to disclose chemsex (AOR 6.68; 95% CI 3.91–11.42; p < 0.001). Those disclosing chemsex had a higher incidence of acute bacterial STIs (AOR 2.83 CI 1.79–4.47; p < 0.001), rectal STIs (AOR 3.10 CI 1.81–5.32; p < 0.001) or hepatitis C (AOR 15.41 CI 1.50–158.17; p 1⁄4 0.021). HIV incidence in the study period was 1.8% (chemsex) vs. 0.9% (no chemsex) (p 1⁄4 0.61). Chemsex was associated with having more sexual partners, transactional sex, group sex, fisting, sharing sex toys, injecting drug use, higher alcohol consumption and the use of ‘bareback’ sexual networking applications (p < 0.004). Chemsex participants were also more likely to have accessed post- exposure prophylaxis for HIV in the study period and report sex with a discordant HIV or hepatitis C-infected partner (p < 0.001). Chemsex disclosure is associated with higher risk-taking behaviours, acute bacterial STIs, rectal STIs and hepatitis C incidence. HIV incidence was higher but not significantly so in the study period. Chemsex disclosure in sexual health clinics should prompt an opportunity for prevention, health promotion and wellbeing interventions

The prevalence of tinnitus and the relationship with neuroticism in a middle-aged UK population

Background: Previous research has suggested that a substantial proportion of the population are severely affected by tinnitus, however recent population data are lacking. Furthermore, there is growing evidence that the perception of severity is closely related to personality factors such as neuroticism. Objective: In a subset (N = 172,621) of a large population sample of > 500,000 adults aged 40 to 69 years, (from the UK Biobank dataset) we calculated the prevalence of tinnitus and that which is perceived as bothersome, and examined the association between tinnitus and a putative predisposing personality factor, neuroticism. Method Participants were recruited through National Health Service registers and aimed to be inclusive and as representative of the UK population as possible. The assessment included subjective questions concerning hearing and tinnitus. Neuroticism was self-rated on 13 questions from the Eysenck Personality Inventory. Associations between neuroticism and tinnitus were tested with logistic regression analyses. Results:Prevalence of tinnitus was significantly higher for males, and increased with age, doubling between the youngest and oldest age groups (males 13% and 26%; females 9% and 19% respectively). Of those with tinnitus, females were more likely to report bothersome tinnitus. Neuroticism was associated with current tinnitus and bothersome tinnitus, with the items: ‘loneliness’, ‘mood swings’, ‘worrier/anxious’ and ‘miserableness’, as the strongest associations of bothersome tinnitus. Conclusions: Neuroticism was identified as a novel association with tinnitus. Individuals with tinnitus and higher levels of neuroticism are more likely to experience bothersome tinnitus, possibly as a reflection of greater sensitivity to intrusive experiences
