A Tobacco-Free Future - An all-island report on tobacco, inequalities and childhood 2013 reveals declines in smoking rates among both children and pregnant women over the past decade, both North and South of the border. This report published by the Institute of Public Health in Ireland (IPH) and the TobaccoFree Research Institute Ireland (TFRI), shows that while tobacco control measures are being successful, disadvantaged children are at particular risk of tobacco-related harms.

In a field collection performed at Pan de Azúcar Island in Northern Chile, 95 specimens representing all instars of Mepraia spinolai were collected. The intestinal contents of 55 specimens were examined for Trypanosoma cruzi infection and were found to be negative. This is the first record of an insular habitat for M. spinolai, where the insects had fed mainly on seabirds (78%), some on marine mammals (5%), and some on reptiles (7%).

The nuclear phenotypes of Malpighian tubule epithelial cells of male nymphs of the blood-sucking insect, Panstrongylus megistus, subjected to short- and long-duration heat shocks at 40ºC were analyzed immediately after the shock and 10 and 30 days later. Normal nuclei with a usual heterochromatic body as well as phenotypes indicative of survival (unravelled heterochromatin, giants) and death (apoptosis, necrosis) responses were observed in control and treated specimens. However, all nuclear phenotypes, except the normal ones, were more frequent in shocked specimens. Similarly altered phenotypes have also been reported in Triatoma infestans following heat shock, although at different frequencies. The frequency of the various nuclear phenotypes observed in this study suggests that the forms of cell survival observed were not sufficient or efficient enough to protect all of the Malpighian tubule cells from the deleterious effects of stress. In agreement with studies on P. megistus survival following heat shock, only long-duration shock produced strongly deleterious effects.

Context: GnRH deficiency is a rare genetic disorder of absent or partial pubertal development. The clinical and genetic characteristics of GnRH-deficient women have not been well-described. Objective: To determine the phenotypic and genotypic spectrum of a large series of GnRH-deficient women. Design, Setting, and Subjects: Retrospective study of 248 females with GnRH deficiency evaluated at an academic medical center between 1980 and 2010. Main Outcome Measures: Clinical presentation, baseline endogenous GnRH secretory activity, and DNA sequence variants in 11 genes associated with GnRH deficiency. Results: Eighty-eight percent had undergone pubarche, 51% had spontaneous thelarche, and 10% had 1-2 menses. Women with spontaneous thelarche were more likely to demonstrate normal pubarche (P = 0.04). In 27% of women, neuroendocrine studies demonstrated evidence of some endogenous GnRH secretory activity. Thirty-six percent (a large excess relative to controls) harbored a rare sequence variant in a gene associated with GnRH deficiency (87% heterozygous and 13% biallelic), with variants in FGFR1 (15%), GNRHR (6.6%), and PROKR2 (6.6%) being most prevalent. One woman had a biallelic variant in the X-linked gene, KAL1, and nine women had heterozygous variants. Conclusions: The clinical presentation of female GnRH deficiency varies from primary amenorrhea and absence of any secondary sexual characteristics to spontaneous breast development and occasional menses. In this cohort, rare sequence variants were present in all of the known genes associated with GnRH deficiency, including the novel identification of GnRH-deficient women with KAL1 variants. The pathogenic mechanism through which KAL1 variants disrupt female reproductive development requires further investigation.

An increase in the incidence of human visceral leishmaniasis (HVL) has been detected in recent years on Margarita Island, located off the NE coast of Venezuela. Recent studies have revealed reactivity to rK39 antigen (Leishmania chagasi) in 20% of 541 sera from domestic dogs in endemic communities; PCR reactions were positive using primers for the L. donovani complex. Here we report that isolates from human and canine infection, identified by isoenzyme analysis, correspond to L. infantum, zymodeme MON-1. This appears to be the first isolation and identification of an isolate from HVL on Margarita Island and demonstrates the presence of this zymodeme in the canine population.

Eight alien freshwater snail species were introduced into Martinique Island during the last 50 years. The introduced snails include four planorbids (Biomphalaria straminea, Helisoma duryi, Amerianna carinata and Gyraulus sp.), three thiarids (Melanoides tuberculata, M. amabilis and Tarebia granifera) and one ampullarid (Marisa cornuarietis). Four of these species rapidly colonized the whole Martinican hydrographic system whereas the other four remained restricted to some particular sites. The invasion processes were documented during the last 20 years and showed (i) a rapid invasion of the island by several morphs of M. tuberculata at the beginning of the 80's; (ii) the introduction of T. granifera in 1991 and M. amabilis in 1997; and (iii) the rapid spread of these last two species throughout the island. In the years following its introduction, M. tuberculata was used in biological control experiments against the snail hosts of schistosomiasis, B. glabrata and B. straminea. Experiments were conducted with success in several groups of water-cress beds which constituted the latest transmission sites for schistosomiasis at the beginning of the 80's. A malacological survey carried out in 2000 all over the island showed the absence of B. glabrata but the presence of some residual populations of B. straminea. Long-term studies carried out in Martinique have shown that the thiarids are able to maintain relatively stable populations over a long period of time, thus preventing recolonization by the snail hosts. Within this context the invasion of the hydrographic system of Martinique by thiarid snails has resulted in an efficient and sustainable control of the intermediate hosts of schistosomiasis.

The nuclear phenotypes of Malpighian tubule cells in fifth instar nymphs of Triatoma infestans, one of the most important vectors of Chagas disease, were studied following sequential shocks at 0ºC, separated by intervals of 8 h and 24 h at 30ºC, under conditions of moderate fasting and full nourishment. The insects pertained to colonies reared in the laboratory and originated from domestic specimens collected in the Brazilian states of São Paulo (north) and Minas Gerais (south). Since nuclear phenotypes in this species are affected by single cold shocks, it was expected that these phenotypes could also be changed by sequential shocks. Nuclear phenotypes indicative of mechanisms of cell survival (nuclear fusion and heterochromatin decondensation) and cell death (apoptosis and necrosis) were observed concomitantly in all the conditions tested. Nuclear fusion and heterochromatin decondensation were not found relevant for the presumed acquisition of the cold-hardening response in T. infestans. The decreased frequency of apoptosis and necrosis following sequential cold shocks including under fasting conditions, indicated that tolerance to sequential cold shocks occurred in T. infestans of the mentioned origin.

Sixty-five patients were diagnosed with visceral leishmaniasis (VL) on Margarita Island in the decade from 1990 to1999; 86.2% were <= 3 years old. All were leishmanin-negative at diagnosis. Evaluation of 23 cured patients in 1999 revealed that 22/23 had converted to leishmanin-positive; five had persisting antibodies to rK39 antigen, with no clinical evidence of disease. Leishmanin tests were positive in 20.2% of 1,643 healthy individuals from 417 households in endemic areas. Of the positive reactors, 39.8% were identified in 35 (8.4%) of the households, 15 of which had an antecedent case of VL, a serologically positive dog or both. Weak serological activity to rK39 antigen was detected in 3 of 488 human sera from the endemic areas. The presence of micro-foci of intense peri-urban transmission and the apparent absence of other Trypanosomatidae causing human disease offer a unique opportunity for the study of reservoirs, alternative vectors and evaluation of control measures on the Island.

The findings of a Public Health Agency evaluation report on a suicide prevention training programme were today presented at the North South Ministerial Council Health Sector meeting.ASIST, The Applied Suicide Intervention Skills Training programme, has to date been delivered to more than 20,000 people in the Republic of Ireland and more than 11,000 people in Northern Ireland. This two day course, delivered by a wide range of organisations including those from the voluntary/community sector, for professionals and the public helps individuals provide emergency help to people at risk of suicidal behaviour. It also develops a cooperative network among participants, since often many people have to work together to prevent suicide.Talking about the findings of this work, Dr Eddie Rooney, Chief Executive, PHA, said: "Both the PHA and the National Office for Suicide Prevention (NOSP), based in the Republic of Ireland, are concerned for any loss of life through suicide and we send our condolences to all families who have been bereaved. We know ASIST training brings a positive element to suicide prevention. Those who have been trained said that the two biggest advantages are that they know when, how and have the confidence to help people who are under pressure and that it helps to build positive links between community and voluntary organisations and the health service. I am pleased that this has been borne out in the evaluation and we hope ASIST will continue to be of enormous benefit and will contribute to a reduction in suicidal behaviour and the tragedy that this brings to our community".This evaluation found that within organisations where staff had participated in ASIST training, there were improvements in service development; staff attitudes, confidence and skills in relation to suicide and suicide intervention and in policies and procedures. At a community level, ASIST was found to have contributed to a sense of empowerment through an increased confidence in being able to deal with suicide and suicidal behaviour.The report also shows that the ASIST model offers a common language, helping communication between the community or voluntary organisations and those from a health background. In fact this training helped to cancel out any differences between those with mental health qualifications and those without, in terms of knowledge, skills, attitude and willingness to intervene. The study also confirmed that ASIST training was most relevant to those who were likely to be in contact with a person 'at risk'.In welcoming the publication of the report Geoff Day, Director of the NOSP, said: "This report is an independent evaluation of the ASIST programme, it has allowed us to demonstrate the effectiveness of the programme in increasing community participants confidence and ability to respond to individuals in suicidal crisis.He added: "The fact the evaluation was completed on an all-island basis allows the NOSP and the PHA to avoid duplication of resources, improve coordination of suicide prevention training programmes across both jurisdictions and allows us to learn from different approaches used in suicide prevention across the island of Ireland."He reiterated the Health Service Executive commitment to the continued implementation of quality assured training programmes as part of Reach out: the National Strategy for Action on Suicide Prevention.ASIST training is being rolled out in Northern Ireland as part of the implementation of the 'Protect Life' suicide prevention strategy, which was published by the Department of Health, Social Services and Public Safety in 2006.A copy of the evaluation report can be found below and in the publications section of this website, by clicking here
