Objective:
Social health (SH) markers, including marital status, contact frequency, network size, and social support, have been linked with increased cognitive capability. However, the underlying mechanisms remain poorly understood. We aim to investigate whether depression symptoms and inflammatory biomarkers mediate associations between SH and cognitive outcomes.
Methods:We used data from waves 1-9 of the English Longitudinal Study of Ageing, involving 7,136 participants aged 50 or older at baseline. First, we examined associations between SH (wave 1) and depression and inflammatory biomarkers (C-reactive protein (CRP) and fibrinogen) (wave 2) using linear regression models. Second, we tested associations between a) SH and b) depression and inflammation with subsequent standardised verbal fluency and memory in wave 3 and change between waves 3-9, indexed using slopes derived from multilevel models. We adjusted for age, sex, socio-economic position, cardiovascular disease, basic and instrumental activities of daily living, health behaviours, and baseline depression symptoms and cognition. We will also conduct causal mediation analysis.
Results:All SH markers, except contact frequency, were associated with lower subsequent depression, but not inflammatory biomarkers. Greater contact frequency (e.g. once-twice a week vs <once per year: β=0.18 [0.01, 0.36]) and less negative support (β=0.02 [0.00, 0.03]) were associated with higher verbal fluency. Larger network size (>6 people vs none: β=0.007SD/year [0.001, 0.012]), less negative (β=0.001SD/year [0.001, 0.002]) and more positive support (β=0.001SD/year [0.000, 0.001]) were linked with slower memory decline, and more positive support predicted slower verbal fluency decline (β=0.001SD/year [0.000, 0.001]). Depression symptoms were associated with lower memory and verbal fluency, and faster memory decline (β=-0.001SD/year [-0.001, -0.000]) and verbal fluency (β=-0.001SD/year [-0.001, -0.000]). CRP was associated with lower verbal fluency (β=-0.02 [-0.04, 0.00]), whereas fibrinogen was linked with faster memory decline (β=-0.001SD/year [-0.003, -0.000]).
Conclusion:Depression symptoms and SH showed associations with subsequent cognitive capability and change. SH was linked with lower depression, but not inflammatory biomarkers. Findings highlight the potential for depression to underpin associations between SH and cognition, a pathway which we will test using causal mediation analysis. We will also examine whether findings replicate in the Swedish National Study of Aging and Care in Kungsholmen.

Background
Complex challenges may arise when patients present to emergency services with an advance decision to refuse life-saving treatment following suicidal behaviour.
AimsTo investigate the use of advance decisions to refuse treatment in the context of suicidal behaviour from the perspective of clinicians and people with lived experience of self-harm and/or psychiatric services.
MethodForty-one participants aged 18 or over from hospital services (emergency departments, liaison psychiatry and ambulance services) and groups of individuals with experience of psychiatric services and/or self-harm were recruited to six focus groups in a multisite study in England. Data were collected in 2016 using a structured topic guide and included a fictional vignette. They were analysed using thematic framework analysis.
ResultsAdvance decisions to refuse treatment for suicidal behaviour were contentious across groups. Three main themes emerged from the data: (a) they may enhance patient autonomy and aid clarity in acute emergencies, but also create legal and ethical uncertainty over treatment following self-harm; (b) they are anxiety provoking for clinicians; and (c) in practice, there are challenges in validation (for example, validating the patient’s mental capacity at the time of writing), time constraints and significant legal/ethical complexities.
ConclusionsThe potential for patients to refuse life-saving treatment following suicidal behaviour in a legal document was challenging and anxiety provoking for participants. Clinicians should act with caution given the potential for recovery and fluctuations in suicidal ideation. Currently, advance decisions to refuse treatment have questionable use in the context of suicidal behaviour given the challenges in validation. Discussion and further patient research are needed in this area.

Summary
‘Two roads diverged in a wood, and I–
I took the one less travelled by,
And that has made all the difference.’
Robert Frost (1874–1963)Introduction
Tier 4 CAMHS aim to meet the needs of children and young people with the most complex, severe or persistent mental health problems. Tier 4 services include in-patient care (see Chapter 29), as well as a range of day care and intensive community home-based and outreach services for specific groups of children and young people.
Day services
Early descriptions of child and adolescent mental health day units emphasised 5-day ‘milieu’ provision with a strong emphasis on education and behaviour management (Brown, 1996), whereas now they frequently provide daily focused activities to which children and families are invited, depending on their needs. Currently, about half of UK day services are linked to in-patient units, and many in-patient units have a day programme (Green & Jacobs, 1998). It is impossible to classify day services owing to the enormous range in milieu and interventions provided (Green & Worrall- Davies, 2008). However, day services broadly offer:
• support and transition to community services following in-patient admission;
• intensive 5 days per week treatment packages for children and their families;
• treatment of disruptive behaviour, using multimodal treatment strategies with a combination of individual, family and psychopharmacological interventions;
• specialist management and programmes of care for younger children with developmental disorders such as autism, speech and language disorders or neuropsychiatric disorders;
• intensive intervention aimed at improving family functioning in situations of family breakdown or child maltreatment.
Provision and organisation
Day units can offer assessment and therapeutic services that are more specialised, complex and intensive than out-patient services, although they are still community-based and less disruptive than in-patient admission. Most also have the benefit of educational input. Close liaison with specialised education and Social Services is central to their work. There is general acceptance of the central importance of maintaining attachments and working with whole systems if the complex needs of children are to be met. Day units can work with children and young people individually and in groups, as well as with their families, while keeping the focus of concern within the community and avoiding the ‘out of sight, out of mind’ dilemma of in-patient services.

Effective species conservation depends upon correctly identifying the threats that cause decline or hinder recovery. Because estimates of the relative viability of different populations of Endangered African wild dogs Lycaon pictus are most strongly influenced by adult and pup mortality, we analysed rates and causes of mortality in eight wild dog populations under study in southern and eastern Africa. The probabilities of detecting wild dog deaths were influenced by the monitoring methods used. The least biased estimates of mortality causes were obtained through intensive monitoring of radio-collared individuals; this is impossible for pups, however. Mortality patterns varied substantially between populations. Rates of human-caused mortality were higher for wild dogs radio-collared outside protected areas than for those collared inside, but rates of natural mortality were comparable, suggesting that anthropogenic mortality is additive to natural mortality. The relative importance of factors such as snaring and infectious disease also varied regionally. Hence, although our analyses identified no new threats beyond those highlighted in a 1997 range-wide Action Plan, they suggest that local plans will be valuable to target conservation activities more precisely.
