Variation in suicide rates between Health Board areas

This paper examines variations in suicide in the eight Health Boards of the Republic of Ireland for the years 1976 to 1995. It is found that while all have experienced a rise in male suicide, it has been much less pronounced in the Eastern Health Board which is somewhat surprising when one considers Dublin’s much-publicised problems with homelessness and hard drug misuse. Since the mid-eighties, female rates have been somewhat higher in the southern half of the country, comprising the Southern, Mid-Western and South-Eastern Health Boards. This variation may reflect a difficulty with contacting services for psychological distress in rural areas, either because of stigma or simple practical problems associated with transport. The development of appropriate services, especially in rural areas, should be at the top of the agenda of any Resource Officer to be appointed subsequent to the Final Report of the Task Force.

Suicide and deliberate self harm in older Irish adults

Background: Hospital-treated deliberate self harm and suicide among older adults have rarely been examined at a national level. Methods: The Irish Central Statistics Office provided suicide and undetermined death data for 1980-2006. The National Registry of Deliberate Self Harm collected data relating to deliberate self harm presentations made in 2006-2008 to all 40 Irish hospital emergency departments. Results: Rates of female suicide among older adults (over 55 years) were relatively stable in Ireland during 1980-2006 whereas male rates increased in the 1980s and decreased in more recent decades. Respectively, the annual male and female suicide and undetermined death rate was 22.1 and 7.6 per 100,000 in 1997-2006. Male and female deliberate self harm was 3.0 and 11.0 times higher at 67.4 and 83.4 per 100,000, respectively. Deliberate self harm and suicide decreased in incidence with increasing age. Deliberate self harm generally involved drug overdose (male: 72%; female 85%) or self-cutting (male: 15%; female 9%). The most common methods of suicide were hanging (41%) and drowning (29%) for men and drowning (39%) and drug overdose (24%) for women. City and urban district populations had the highest rates of hospital-treated self harm. The highest suicide rates were in urban districts. Conclusions: Older Irish adults have high rates of hospital-treated deliberate self harm but below average rates of suicide. Drowning was relatively common as a method of suicide. Restricting availability of specific medications may reduce both forms of suicidal behavior.

St. Columba, Silnán, and the 'Male Bovine' (VC 2.17)

At Vita Columbae VC 2.17, Adomnán has severely misunderstood a written source which originally described how Columba ordered one party to a dispute, an alleged maleficus ‘evil-doer’ called Silnán, to milk a sick cow in order to settle the dispute by demonstrating that its contaminated milk was the real, hidden cause of the harm which had occasioned the dispute. Adomnán misread a description of a bos maculosus ‘pock-marked bovine’ to refer to a bos masculus ‘male bovine’, and proceeded to misunderstand the story as the description of some form of contest between Columba and a maleficus ‘sorcerer’.

Tryptophan degradation in irritable bowel syndrome: evidence of indoleamine 2,3-dioxygenase activation in a male cohort

Background: Irritable bowel syndrome (IBS) is a common disorder that affects 10–15% of the population. Although characterised by a lack of reliable biological markers, the disease state is increasingly viewed as a disorder of the brain-gut axis. In particular, accumulating evidence points to the involvement of both the central and peripheral serotonergic systems in disease symptomatology. Furthermore, altered tryptophan metabolism and indoleamine 2,3-dioxygenase (IDO) activity are hallmarks of many stress-related disorders. The kynurenine pathway of tryptophan degradation may serve to link these findings to the low level immune activation recently described in IBS. In this study, we investigated tryptophan degradation in a male IBS cohort (n = 10) and control subjects (n = 26). Methods: Plasma samples were obtained from patients and healthy controls. Tryptophan and its metabolites were measured by high performance liquid chromatography (HPLC) and neopterin, a sensitive marker of immune activation, was measured using a commercially available ELISA assay. Results: Both kynurenine levels and the kynurenine:tryptophan ratio were significantly increased in the IBS cohort compared with healthy controls. Neopterin was also increased in the IBS subjects and the concentration of the neuroprotective metabolite kynurenic acid was decreased, as was the kynurenic acid:kynurenine ratio. Conclusion: These findings suggest that the activity of IDO, the immunoresponsive enzyme which is responsible for the degradation of tryptophan along this pathway, is enhanced in IBS patients relative to controls. This study provides novel evidence for an immune-mediated degradation of tryptophan in a male IBS population and identifies the kynurenine pathway as a potential source of biomarkers in this debilitating condition.
