Can early infection explain the sibling effect in adult atopy

Atopy is strongly and inversely related to family size, a pattern which is plausibly assumed to reflect a protective effect of early infection. The current study tested this hypothesis by case-referent analysis of an adult cohort in the UK. The study established that atopy, defined by prick tests to common aeroallergens, was less common among those from larger families after adjustment for potentially confounding factors. In particular, a higher number of brothers appeared to offer protection. The current authors attempted to explain this distribution by examining contemporary family-doctor records of early childhood infections; and by a number of other indirect indices of early-life “hygiene”. The sibling effect was unexplained by evidence of infection with either hepatitis A or Helicobacter pylori, or by counts of infections or antibiotic prescriptions in early life. There was a significant and independent negative association between the number of gastrointestinal infections before the age of 5 yrs and the odds of atopy. Dog ownership and home moving in early life also displayed potentially protective associations. Although the current study replicates the finding that atopy is inversely associated with family size this could not be explained by documentary or serological evidence of early infection. The findings support the suggestion that the “sibling effect” in atopy may not simply reflect protection by early infection.

Understanding vulnerability to self-harm in times of economic hardship and austerity: a qualitative study.

Objective Self-harm and suicide increase in times of economic recession, but little is known about why people self-harm when in financial difficulty, and in what circumstances self-harm occurs. This study aimed to understand events and experiences leading to the episode of self-harm and to identify opportunities for prevention or mitigation of distress. Setting Participants’ homes or university rooms. Participants 19 people who had attended hospital following self-harm in two UK cities and who specifically cited job loss, economic hardship or the impact of austerity measures as a causal or contributory factor. Primary and secondary outcome measures Semistructured, in-depth interviews. Interviews were audio recorded, transcribed and analysed cross-sectionally and as case studies. Results Study participants described experiences of severe economic hardship; being unable to find employment or losing jobs, debt, housing problems and benefit sanctions. In many cases problems accumulated and felt unresolvable. For others an event, such as a call from a debt collector or benefit change triggered the self-harm. Participants also reported other current or past difficulties, including abuse, neglect, bullying, domestic violence, mental health problems, relationship difficulties, bereavements and low self-esteem. These contributed to their sense of despair and worthlessness and increased their vulnerability to self-harm. Participants struggled to gain the practical help they felt they needed for their economic difficulties or therapeutic support that might have helped with their other co-existing or historically damaging experiences. Conclusions Economic hardships resulting from the recession and austerity measures accumulated or acted as a ‘final straw’ to trigger self-harm, often in the context of co-existing or historically damaging life-experiences. Interventions to mitigate these effects should include providing practical advice about economic issues before difficulties become insurmountable and providing appropriate psychosocial support for vulnerable individuals.

Seeking help in times of economic hardship: access, experiences of services and unmet need

BackgroundEconomic recessions are often accompanied by increased levels of psychological distress and suicidal behaviour in affected populations. Little is known about the experiences of people seeking help for employment, financial and benefit-related difficulties during recessions. We investigated the experiences of people struggling financially in the aftermath of the Great Recession (2008-9) - including some who had self-harmed - and of the frontline support staff providing assistance.MethodsInterviews were conducted with three groups of people in two cities: i) people who had self-harmed due to employment, financial or benefit concerns (n = 19) (‘self-harm’); ii) people who were struggling financially drawn from the community (n = 22), including one focus group) (‘community’); iii) and frontline staff from voluntary and statutory sector organisations (e.g., Job Centres, Debt Advice and counselling agencies) providing support services to the groups (n = 25, including 2 focus groups) (‘service providers’). Data were analysed using the constant comparison method.ResultsService provision was described by people as confusing and difficult to access. The community sample reported considerably more knowledge and access to debt advice than the participants who had self-harmed – although both groups sought similar types of help. The self-harm group exhibited greater expectation that they should be self-reliant and also reported lower levels of informal networks and support from friends and relatives. They had also experienced more difficult circumstances such as benefit sanctions, and most had pre-existing mental health problems. Both self-harm and community groups indicated that practical help for debt and benefit issues would be the most useful – a view supported by service providers - and would have particularly helped those who self-harmed.ConclusionInterventions to identify those in need and aid them to access practical, reliable and free advice from support agencies could help mitigate the impact on mental health of benefit, debt and employment difficulties for vulnerable sections of society.

Management of treatment-resistant depression in primary care: a mixed-methods study

Background Non-response to antidepressant medication is common in primary care. Little is known about how GPs manage patients with depression that does not respond to medication. Aim To describe usual care for primary care patients with treatment-resistant depression (TRD). Design and setting Mixed-methods study using data from a UK primary care multicentre randomised controlled trial. Method In total, 235 patients with TRD randomised to continue with usual GP care were followed up at 3-month intervals for a year. Self-report data were collected on antidepressant medication, number of GP visits, and other treatments received. In addition, 14 semi-structured face-to-face interviews were conducted with a purposive sample after the 6-month follow-up and analysed thematically. Results Most patients continued on the same dose of a single antidepressant between baseline and 3 months (n = 147/186 at 3 months, 79% (95% confidence interval [CI] = 73 to 85%)). Figures were similar for later follow-ups (for example, 9–12 months: 72% (95% CI = 63 to 79%). Medication changes (increasing dose; switching to a different antidepressant; adding a second antidepressant) were uncommon. Participants described usual care mainly as taking antidepressants, with consultations focused on other (physical) health concerns. Few accessed other treatments or were referred to secondary care. Conclusion Usual care in patients with TRD mainly entailed taking antidepressants, and medication changes were uncommon. The high prevalence of physical and psychological comorbidity means that, when these patients consult, their depression may not be discussed. Strategies are needed to ensure the active management of this large group of patients whose depression does not respond to antidepressant medication.
