The aim of this study was to investigate cause‐specific premature death in individuals who self‐harm, including associations with socioeconomic deprivation. Methods h d We undertook a cohort study of patients of all ages presenting to emergency departments in Oxford, Manchester, and Derby, UK, after self‐poisoning or self‐injury between Jan 1, 2000, and Dec 31, 2007. Postcodes of individuals' place of residence were linked to the Index of Multiple Deprivation 2007 in England. Mortality information was supplied by the Medical Research Information Service of the National Health Service. Patients were followed up to t e e d o 009 e ca cu ated age sta da d sed o ta ty at os (S s) a d yea s o e ost ( ), a d e tested o assoc at o s t soc oeco o c the end of 2009. We calculated age‐standardised mortality ratios (SMRs) and years of life lost (YLL), and we tested for associations with socioeconomic deprivation. Findings 30 950 individuals presented with self‐harm and were followed up for a median of 6∙0 years (IQR 3∙9—7∙9). 1832 (6∙1%) patients died before the end of follow‐up. Death was more likely in patients than in the general population (SMR 3∙6, 95% CI 3∙5—3∙8), and occurred more in males (4∙1, 3∙8—4∙3) than females (3∙2, 2∙9—3∙4). Deaths due to natural causes were 2—7∙5 times more frequent than was expected. For individuals who died of any cause, mean YLL was 31∙4 years (95% CI 30∙5—32∙2) for male patients and 30∙7 years (29∙5—31∙9) for female patients. Mean YLL for natural‐cause deaths was 25∙9 years (25∙7—26∙0) for male patients and 25∙5 years (25∙2—25∙8) for female patients, and for external‐cause deaths was 40∙2 years (40∙0—40∙3) and 40∙0 years (39∙7—40∙5), respectively. Disease of the circulatory (13∙1% in males; 13∙0% in females) and digestive (11∙7% in males; 17∙8% in females) systems j y q p p (χ were major contributors to YLL from natural causes. All‐cause mortality increased with each quartile of socioeconomic deprivation in male patients (χ2 trend 39∙6; p<0∙0001), female patients (13∙9; p=0∙0002), and both sexes combined (55∙4; p<0∙0001). Socioeconomic deprivation was related to mortality in both sexes combined from natural causes (51∙0; p<0∙0001) but not from external causes (0∙30; p=0∙58). Alcohol problems were associated with death from digestive‐system disease, drug misuse with mental and behavioural disorders, and physical health problems with circulatory‐system disease. Interpretation Ph i l h l h d lif Physical health and life expectancy are severely compromised in individuals who self‐harm compared with the general population. In the management l i d i i di id l h lf h d ih h l l i I h of self‐harm, clinicians assessing patients' psychosocial problems should also consider their physical needs.

(2008) Shabbir Amanullah (Royal College of Psychiatrists 201: 174 doi: 10.1192/bjp.bp.111.106229) From a therapeutic point of view psychiatry as a specialty is in an unenviable position If despite extensive From a therapeutic point of view, psychiatry as a specialty is in an unenviable position. If, despite extensive • interventions, a patient takes his or her own life, the physician is often perceived as having failed that person. Rarely is a consultant oncologist challenged about a non‐responsive patient: ‘surely, there must be something you could have done differently?’ Despite rapid advances across medicine, psychiatrists frequently wonder why placebos work ‘just as well’ in some disorders. • Rethinking how the mind, in all its complexity and might, is deeply fallible may help us. In depression, negative automatic thoughts prevent people from functioning normally; in post‐traumatic stress disorder, a distressing memory can almost take on a ‘life memory can almost take on a life of its own of its own’. In obsessive–compulsive disorder, one is confronted with a In obsessive–compulsive disorder one is confronted with a persistence of such thoughts despite insight that they are ‘silly’. As phenomena, the thoughts appear to be ‘against the mind’ • That the mind chooses to attack itself is in itself analogous to the body’s autoimmune reaction. We assume g y that childhood events shape our subsequent reactions to events. Why then do apparently well‐adapted individuals struggle or indeed develop depression in later life? From a non‐biological perspective, how do some of the most accomplished people have low self‐esteem? Evidence and clinical experience support a combination of different interventions for psychiatric disorders One target is the immediate ‘inflammatory’ combination of different interventions for psychiatric disorders. One target is the immediate inflammatory response, and perhaps psychoactive medications for agitation/anxiety do that, but parallel to this, antidepressants and antipsychotics may act like immune suppressants – as thought suppressants. We know that psychotherapeutic approaches help, but we may need to add meditation to our interventions in an effort to suppress extraneous unwanted thoughts, as alternatives to the conventional combination of psychotherapy and psychopharmacology.

In humans, vitamin D is unique q both because it functions as a prohormone and because the body can synthesize it (as vitamin D3) when sun exposure is adequate (hence its nickname, the "sunshine vitamin").

Fatty acids (“fish fish oil oil”)) 3. Vitamins & minerals 5. Patients and us, dietary advice What can we do with all this information? In a perfect world, we would maybe change the way we live and eat, for our selves, our families, AND our patients. However reality is that this is not easy at all However, reality is that this is not easy at all. Starting with self is probably the first realistic step, although clinicians who work in in‐patient settings have some chance of applying this knowledge to current patients (I have experienced that occasionally committed families can make adjustments to their life‐style and dietary patterns, leading to clinically meaningful improvements but it really needs commitment (and the world is against them) meaningful improvements, but it really needs commitment (and the world is against them) So here is my ‘shot’ at trying to change you: 1. Get your vitamin D levels checked, and supplement to level of at least 100nmol/L 2. Think about omega‐3 supplementation g pp 3. Think about your nutrition and eating patterns official advice: ‘THE MANTRA’ mixed and varied 5 portions of ‘fruit and veg’ a day Better Advice Evidence based follow up studies show that Evidence based follow up studies show that different advice would work much better: • Stampfler & Willett et al. @ Harvard have published extensively see below published extensively ‐ see below • Michael Pollan (non‐academic ‘food writer’) ( ) Do not eat anything that your (great‐) grandmother would not recognise as food would not recognise as food • tailored to individual – nutritional genomics g Stampfler & Willet ‐ p Harvard BE LIKE A SUPPLEMENT EATER: 1. 2. 3. 4.
