Irish Travellers are an indigenous ethnic minority (IEM) with poor health outcomes. Whilst they constitute less than 1% of the Irish population, they account for 10% of national young adult male suicide statistics.
Methods:
A rapid review of scientific publications related to mental health and suicide in Irish Travellers was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Searches of PubMed, PsycINFO and Google Scholar were performed. Eligibility criteria included: (i) Irish Travellers/Gypsy Travellers; (ii) information on mental health/suicide/self-harm; (iii) psychosocial anthropological perspectives of mental health; (iv) publications in english. Data on studies including design, methods, participants and key findings were extracted using a spreadsheet template.
Results:
From 5160 scientific references over the past 20 years, 19 papers made reference to Traveller mental health, and only 5 papers made specific data-based reference to suicide in Travellers. It was only when we qualified Travellers as being ‘Irish Travellers’ in our scientific review did we detect meaningful references to their existence as an IEM, and their health and well-being. Due to sample sizes and heterogeneity in design, results were synthesised narratively.
Discussion:
This paper draws together strands from the disciplines of psycho/socio/anthropological perspectives to gain deeper insights into mental health and suicide in Irish Travellers. In a knowledge vacuum, it behoves the scientific community to explain the value of scientific research and rigour to both policymakers as well as Travellers, shifting the existing discourse towards new knowledge and understanding around mental health and suicide in Travellers.
Irish Travellers are an indigenous ethnic minority population in Ireland, with poor life expectancy. This study aims to identify factors associated with reported discrimination and how this affects their experiences of accessing and quality of health services, including mental health.
Methods:
The All Ireland Traveller Health Study was a cross-sectional census study in 2010. All Traveller families completed a survey questionnaire (n = 6540), and at random an adult selected from the family completed either a health status (health status study = 1547) or health services utilisation survey (HSU = 1576). Experience of discrimination (EOD) from the census was analysed in relation to HSU data on services used in the previous 12 months and reported experiences of access and quality of that health service. Census variables were analysed in relation to EOD and perceived discrimination (PD).
Results:
In the final models, EOD and PD were significantly associated with socio-demographic, socio-cultural and living conditions. The multivariate odds of reporting EOD ranged from OR 1.84 to 2.13 and were significant for those reporting worse opportunities in accessing health services, mental health (p = 0.001), hospitals (p < 0.001) and public health nurses (p < 0.001). The multivariate odds of reporting EOD ranged from OR 1.95 to 2.71 and remained significant for those who reported they had poorer experiences than others when using health services, quality of experience (OR 2.18, p =< 0.001), trust in providers (OR 1.95, p =< 0.001) and appropriate information (OR 2.71, p =< 0.001).
Conclusions:
Travellers experience high levels of discrimination which negatively affects their engagement with health services. Culturally competent services need to be developed.
The nucleoredoxin-like gene Nxnl1 (Txnl6) and
its paralogue Nxnl2 encode the rod-derived cone viability
factors (RdCVF and RdCVF2), which increase the resistance to photooxidative
damage and have therapeutic potential for the survival of cones in retinitis
pigmentosa. In this study, the transcription of Nxnl genes was
investigated as a function of the day/night cycle in rats. The transcript levels
of Nxnl1 and Nxnl2 were seen to display daily
rhythms with steadily increasing values during the light phase and peak
expression around dark onset in preparations of whole retina, photoreceptor
cells and—but only in regard to Nxnl1—in
photoreceptor-related pinealocytes. The cycling of Nxnl1 but
not that of Nxnl2 persisted in constant darkness in the retina.
This suggests that daily regulation of Nxnl1 is driven by a
circadian clock, whereas that of Nxnl2 is promoted by
environmental light. The present data indicate clock- and light-dependent
regulations of nucleoredoxin-like genes that may be part of a protective shield
against photooxidative damage.
Allopregnanolone protects the fetal brain and promotes normal development including myelination. Preterm birth results in the early separation of the infant from the placenta and consequently a decline in blood and brain allopregnanolone concentrations. Progesterone therapy may increase allopregnanolone and lead to improved oligodendrocyte maturation. The objectives of this study were to examine the efficacy of progesterone replacement in augmenting allopregnanolone concentrations during the postnatal period and to assess the effect on cerebellar myelination – a region with significant postnatal development. Preterm guinea pig neonates delivered at 62 days of gestation by caesarean section received daily s.c. injections of vehicle (2-Hydroxypropyl-β-cyclodextrin) or progesterone (16 mg/kg) for 8 days until term-equivalent age (TEA). Term delivered controls (PND1) received vehicle. Neonatal condition/wellbeing was scored, and salivary progesterone was sampled over the postnatal period. Brain and plasma allopregnanolone concentrations were measured by radioimmunoassay; cortisol and progesterone concentrations were determined by enzyme immunoassay; and myelin basic protein (MBP), proteolipid protein (PLP), oligodendroctye transcription factor 2 (OLIG2) and platelet-derived growth factor receptor-α (PDGFRα) were quantified by immunohistochemistry and western blot. Brain allopregnanolone concentrations were increased in progesterone-treated neonates. Plasma progesterone and cortisol concentrations were elevated in progesterone-treated male neonates. Progesterone treatment decreased MBP and PLP in lobule X of the cerebellum and total cerebellar OLIG2 and PDGFRα in males but not females at TEA compared with term animals. We conclude that progesterone treatment increases brain allopregnanolone concentrations, but also increases cortisol levels in males, which may disrupt developmental processes. Consideration should be given to the use of non-metabolizable neurosteroid agonists.
Youth and young adult suicide has increasingly appeared on international vital statistics as a rising trend of concern in age-specific mortality over the past 50 years. The reporting of suicide deaths in 5-year age bands, which has been the international convention to date, may mask a greater understanding of year-on-year factors that may accelerate or ameliorate the emergence of suicidal thoughts, acts and fatal consequences. The study objective was to identify any year-on-year period of increased risk for youth and young adult suicide in the UK and Ireland.
Methods.
Collation and examination of international epidemiological datasets on suicide (aged 18–35) for the UK and Ireland 2000–2006 (N = 11 964). Outcome measures included the age distribution of suicide mortality in international datasets from the UK and Ireland, 2000–2006.
Results.
An accelerated pattern of risk up to the age of 20 for the UK and Ireland which levels off moderately thereafter was uncovered, thus identifying a heretofore unreported age-related epidemiological transition for suicide.
Conclusions.
The current reporting of suicide in 5-year age bands may conceal age-related periods of risk for suicide. This may have implications for suicide prevention programmes for young adults under age 21.
The association of infants’ birth weight with maternal cardiovascular morbidity (CVD) and mortality substantiates the foetal origins hypothesis. Few studies to date have investigated grandparent–infant risk association. We prospectively examined this relationship in the Lifeways three-generation familial cohort, contrasting lineage and gender differences to understand mechanisms of intergenerational risk transmission. In 2001, a cohort of 1082 families was established at antenatal stage. A total of 539 families (n = 539 infants) had both a participating grandparent (n = 1054) and information on infants’ gestational age. At baseline, grandparents provided their diagnosed CVD status and 79% also underwent a cardiovascular risk factors assessment. In 2005, general practitioners provided an update for 61% grandparents. In 2010, a search of civil register confirmed 77 grandparental deaths in 539 families. Grandchildren's birth weight and grandparental cardiovascular risk factors associations were examined with linear regressions. Grandparental CVD associations were analysed using ANCOVA. Cox proportional hazard ratios (HR) were calculated for all-cause mortality associations. Models were adjusted for infants’, mothers’ and grandparents’ demographic, anthropometric and socio-behavioural characteristics, as appropriate. The paternal grandfathers’ (PGF) systolic blood pressure (mmHg) [β (95% CI) = 6.6 (0.8 – 12.5); P = 0.03] and paternal grandmothers’ serum triglycerides (mmol/l) [β (95% CI) = 78.8 (7.0 – 150.7); P = 0.03] were linearly predictive of infants’ birth weight, which was not observed for maternal grandparents. Mean birth weight for infants of maternal grandmothers with diabetes {−272.7 [(−499.7) − (−45.6)] g; P = 0.02} or stroke {−292.1 [(−544.5) − (−39.6)] g; P = 0.02} was lower than those without diabetes or stroke, a pattern not observed for paternal grandparents. Whereas PGFs’ mortality was significantly associated with infants’ high birth weight (⩾4000 g) [HR (95% CI) = 4.9 (1.2 – 19.9); P = 0.03], maternal grandparents’ mortality showed a converse pattern with infants’ low birth weight (<2500 g) [HR (95% CI) = 1.7 (0.4 – 8.2); P = 0.7], although not statistically significant. These findings suggest that intergenerational transmission of risk differs in maternal and paternal lines.
Members of the public are exposed to radiation because of where they live and their habits bring them into contact with sources of radiation. They may be exposed directly by the source, by direct irradiation or inhalation of released activity or indirectly by exposure to contaminated environmental materials such as food. Consequently habit data are an essential part of dose assessment for members of the public [1]. Previously no detailed surveys had been undertaken in Ireland of habit data relevant to the assessment of doses to the population from radioactivity in the marine environment. Instead RPII dose assessments were made on the basis of assumed or notional data inferred from habit surveys undertaken elsewhere and from national average consumption figures. Following a tender process the Centre for Environment, Fisheries & Aquaculture Science, Cefas, UK, were commissioned to undertake a Habits Survey. Its report [2] provides an assessment of aquatic radiation exposure pathways in Ireland relating to anthropogenic radioactivity in the Irish Sea.
One hundred geriatric psychiatric patients were examined with the Geriatric Mental State Schedule in New York and London, and a correlation procedure involving both clinical and statistical operations was carried out on the psychopathological data thus collected. Twenty-one factors were produced, including three dealing with cognitive impairment. Although it was found that elderly depressives show a profile of psychopathology quite different from that shown by patients with organic disorder, it was also found that patients with an apparently functional disorder may sometimes be diagnosed as an organic disorder, that subjective complaints of intellectual impairment are not good indicators of organic disorders and may be associated with a depressive factor, and that complaints that could be dismissed as attributes of ageing may actually be indicative of a depressive disorder in the elderly. The methodological implications, as well as the limitations of the sample size, are discussed.
Glycosylation variants of the virulent Leishmania major clone VI21 were generated by mutagenesis with N-methyl-N-nitroso-N-nitroguanidine and selected using the galactose-specific lectin Ricinus communis II (RCA II). Three mutants, 4B9, 1D1 and 1C12, which failed to bind RCA II, were found to have an altered expression of lipophosphoglycan (LPG), a molecule implicated in the attachment to host macrophages and survival within the phagolysosome. There were differences in the antigenicity, molecular weight and localization of LPG from mutant parasites as compared to V121. Expression of gp63, a surface molecule also implicated in attachment to macrophages, was unaltered. All 3 mutants caused disease when injected into genetically susceptible BALB/c mice but lesions developed at a much slower rate than those caused by the virulent V121 clone. This slow rate of lesion development did not correlate with promastigotes' ability to invade macrophages in vitro. Karyotype analysis showed that there was a reduction in the size of chromosome band number 2 in all 3 mutants. The differences in LPG and chromosome band 2 were retained by mutant clones following passage through mice, suggesting that these phenotypes are stable. Although the mutant parasites were infective and caused lesions, the changed structure of the LPG appeared to influence the virulence of the parasites.
The paper deals with a specific aspect of a general survey, that is being carried out during last ten years in several regions of Serbia (former Yugoslavia, former Serbia and Montenegro) to assess population exposure to natural radioactivity based on geochemical and integrative pattern research approach. The originality regarding this work is related to the facts such as follows: the first identification and assessment of high areas of natural radiation in Serbia which provides insight into its regional characteristics, the interpretation of the results in terms of geological aspects, building types and human habits, the first introduction and field applicability of both (surface and volume trap) retro techniques in Serbia and assessment of doses and risks to the population in investigated high natural radiation rural communities.
Irish participation in the EU-supported DAta Food NEtworking (DAFNE) project required compliance with the overall aims and objectives. The Irish Household Budget Survey (HBS) expenditure data had to be transformed into a format compatible with the collaborative effort, by converting them into quantities of foodstuffs available per person per day.
Setting
The Irish 1987 HBS expenditure data on all commodities for 7705 households in the Republic of Ireland, collected using a 14-day diary kept by all members of the household aged 15 years and over.
Design
Following identification of 188 food items in the HBS dataset, retail prices per unit weight were sought for each food. Adjustment of prices, collected from a number of different sources, was made to those of 1987 using the Consumer Price Index. Simple models were used to estimate household food availability through application of the adjusted retail prices per unit weight to the expenditure data. The household level data were converted to food availability per person per day. An internal validation of quantities estimated using the retail prices was made using the 12 foodstuffs for which the Irish HBS collects expenses and quantities.
Results
The comparison of quantities published by the Irish Central Statistics Office for 12 foodstuffs in the Irish 1987 Household Budget Survey with the quantities estimated using equivalent expenditure data and corresponding retail prices showed agreement, with less than a 10% margin of error for 10 of the foods.
Conclusion
In spite some difficulty in converting HBS food expenditure data into food availability per person per day, the DAFNE approach is potentially useful for Irish nutrition surveillance purposes and for facilitating comparisons of the Irish HBS food data with those of other European countries.
The electromigration drift velocity of Al in Al(3wt.% Si), Al(2wt.%Cu), and Al(2wt.%Cu,3wt.%Si) was measured in a temperature range 133 to 220 °C with current densities of 1.0 to 1.5×106A/cm2. In Al(3wt.% Si), a significant Al depletion at the cathode end and accumulation at the anode end of stripe were observed within a few hours at 1.5×106A/cm2 and 200°C. In addition, local hillocks and voids along the metal lines were observed. For Al(Cu,Si), the Al drift velocity was slowed down by Cu addition. The majority of hillocks started to grow at a distance about 6 μm away from the cathode end with current density of 1.5×106 A/cm2. The drift velocity of Al in Al(Cu,Si) was found to be a function of time starting with an initial low value and increasing to a an final steady-state value. The behavior was attributed to the migration of Cu and dissolution of Al2Cu precipitates. The activation energies of the depletion 3 Aμm of Al(2%,Cu, 3%Si) was determined to be 0.90±02 eV. The dissolution and growth of A12Cu in the tested samples of Ti/Al(2%Cu)/Ti/TiN were observed using the scanning electron microscope and an electron microprobe.
