RESUMEN
BACKGROUND: The Irish Health Service Executive (HSE) had set a target that all HSE facilities should implement the HSE Tobacco Free Campus (TFC) policy by 2015. AIM: The aims of this study are to examine hospital staff awareness and to assess the progress of selected HSE health care facilities towards a TFC policy. METHODS: Three health care facilities that were conveniently located were self-selected in County Cork, namely, an acute hospital, a mental health service and an older person's facility. Three different types of quantitative data were collected between May and September 2016 drawn on Standards 3, 4 and 5 of the European Network for Tobacco Free Health Care Services (ENSH-Global) tools: (1) face-to-face consultation with health care facility managers on their progress towards the HSE TFC policy, (2) self-administered questionnaire to a purposive sample of 153 staff members across three health care facilities and (3) physical observation of signs of smoking and smoking-related information across each health care facility for objective verification of compliance. RESULTS: Of the 153 staff who completed the questionnaire, 64% were females, 39% were nurses, 20% were smokers and 76% agreed with the TFC policy. However, only 26% of the 153 staff had received training on motivational and tobacco cessation techniques. Seventy-seven percent of the 153 staff stated that the campus was not tobacco-free. Physical observation suggested signs of smoking within the campus across all three health care facilities surveyed. CONCLUSION: Staff awareness of the HSE TFC policy across selected health care facilities in Ireland is positive but is not sufficient. There are gaps in the implementation process of the HSE TFC policy in the health care facilities. Therefore, proper communication on the importance of the ENSH-Global standards and cessation training to all staff is necessary to help reduce smoking rates across the health care facilities and also to move towards a Tobacco Free Campus in Ireland.

CACNA1C, encoding the Cav1.2 subunit of L-type Ca2+ channels, has emerged as one of the most prominent and highly replicable susceptibility genes for several neuropsychiatric disorders. Cav1.2 channels play a crucial role in calcium-mediated processes involved in brain development and neuronal function. Within the CACNA1C gene, disease-associated single-nucleotide polymorphisms have been associated with impaired social and cognitive processing and altered prefrontal cortical (PFC) structure and activity. These findings suggest that aberrant Cav1.2 signaling may contribute to neuropsychiatric-related disease symptoms via impaired PFC function. Here, we show that mice harboring loss of cacna1c in excitatory glutamatergic neurons of the forebrain (fbKO) that we have previously reported to exhibit anxiety-like behavior, displayed a social behavioral deficit and impaired learning and memory. Furthermore, focal knockdown of cacna1c in the adult PFC recapitulated the social deficit and elevated anxiety-like behavior, but not the deficits in learning and memory. Electrophysiological and molecular studies in the PFC of cacna1c fbKO mice revealed higher E/I ratio in layer 5 pyramidal neurons and lower general protein synthesis. This was concurrent with reduced activity of mTORC1 and its downstream mRNA translation initiation factors eIF4B and 4EBP1, as well as elevated phosphorylation of eIF2α, an inhibitor of mRNA translation. Remarkably, systemic treatment with ISRIB, a small molecule inhibitor that suppresses the effects of phosphorylated eIF2α on mRNA translation, was sufficient to reverse the social deficit and elevated anxiety-like behavior in adult cacna1c fbKO mice. ISRIB additionally normalized the lower protein synthesis and higher E/I ratio in the PFC. Thus this study identifies a novel Cav1.2 mechanism in neuropsychiatric-related endophenotypes and a potential future therapeutic target to explore.

Brain Cav 1.2 and Cav 1.3 L-type Ca2+ channels play key physiological roles in various neuronal processes that contribute to brain function. Genetic studies have recently identified CACNA1C as a candidate risk gene for bipolar disorder (BD), schizophrenia (SCZ), major depressive disorder (MDD) and autism spectrum disorder (ASD), and CACNA1D for BD and ASD, suggesting a contribution of Cav 1.2 and Cav 1.3 Ca2+ signalling to the pathophysiology of neuropsychiatric disorders. Once considered sole clinical entities, it is now clear that BD, SCZ, MDD and ASD share common phenotypic features, most likely due to overlapping neurocircuitry and common molecular mechanisms. A major future challenge lies in translating the human genetic findings to pathological mechanisms that are translatable back to the patient. One approach for tackling such a daunting scientific endeavour for complex behaviour-based neuropsychiatric disorders is to examine intermediate biological phenotypes in the context of endophenotypes within distinct behavioural domains. This will better allow us to integrate findings from genes to behaviour across species, and improve the chances of translating preclinical findings to clinical practice.

OBJECTIVES: To estimate and identify characteristics of tobacco use, including use of roll-your-own (RYO) cigarettes and second-hand smoke (SHS) exposure, among a self-identified lesbian, gay, bisexual and transgender (LGBT) community in Ireland. STUDY DESIGN: Web-based self-administered questionnaire survey using a cross-sectional study design. METHODS: A convenience sample of 661 self-identified LGBT respondents was recruited through a well-advertised web-based survey tool method between March and May 2012. Prevalence rates were adjusted for age, sexual orientation, social class and nationality. Multivariable logistic regression was performed to characterize tobacco use profile and SHS exposure levels for estimating adjusted odds ratios (AOR) with 95% confidence intervals (CI). RESULTS: Of the 661 respondents, 45.3% (95% CI 44.9-45.7) reported current use of tobacco and 15.6% reported current use of RYO cigarettes (results were significantly higher for lesbians in both categories). In addition, 40.3% (95% CI 39.9-40.6) of respondents reported SHS exposure at home (significantly higher in gays), and 50.1% (95% CI 49.3-50.8) reported SHS exposure in cars (significantly higher in lesbians); these two groups were not mutually exclusive. The oldest individuals and non-Irish nationals were more than twice as likely to report SHS exposure in cars compared with the youngest individuals and Irish nationals, and the least-educated individuals were more than twice as likely to report current use of RYO cigarettes compared with the most-educated individuals (AOR 2.26; 95% CI 1.06-4.79). Non-tobacco users were less likely to report SHS exposure at home compared with current tobacco users (AOR 0.31; 95% CI 0.21-0.46). DISCUSSION: Despite inherent methodological limitations associated with identification of such a study sample, the adjusted rates indicate that tobacco use is very high among the LGBT community in Ireland compared with the general Irish population (smoking rate 29%). High levels of SHS exposure at home and in cars further underscore the significance of smoke-free private vehicle and 100% smoke-free home policies. A targeted tobacco control strategy should be explored for this vulnerable population.

OBJECTIVES: To determine the prevalence of metabolic syndrome and to identify predictors for the same, specific to an underdeveloped urban locale of Eastern India. STUDY DESIGN: Population-based cross-sectional study, with multistage random sampling technique. SETTING: Urban city-dwellers in Orissa one of the poorest states of Eastern India bordering a prosperous state of Andhra Pradesh of Southern India. PARTICIPANTS: 1178 adults of age 20-80 years randomly selected from 37 electoral wards of the urban city. Definition of Metabolic Syndrome: We followed a unified definition of the metabolic syndrome by joint interim statement of five major scientific organizations - the International Diabetes Federation, the National Heart, Lung, and Blood Institute, the American Heart Association, the World Heart Federation, the International Atherosclerosis Society, and the International Association of the Study of Obesity. Individuals who meet at least three of five clinical criteria of abdominal obesity, hypertriglyceredimia, low HDL, hypertension, and hyperglycemia are diagnosed as having the condition; presence of none of these criteria is mandatory. Explicit cut points are defined for all criteria, except elevated waist circumference, which must rely on population and country-specific definitions. MAIN OUTCOME MEASURE: Prevalence and significant predictors of metabolic syndrome. STATISTICAL ANALYSIS: Both descriptive and multivariable logistic regression analyses. RESULTS: Age-standardized prevalence rates of metabolic syndrome were 33.5% overall, 24.9 % in males and 42.3% in females. Older age, female gender, general obesity, inadequate fruit intake, hypercholesterolemia, and middle-to-high socioeconomic status significantly contributed to increased risk of metabolic syndrome. CONCLUSION: Metabolic syndrome is a significant public health problem even in one of the poorest states of India that needs to be tackled with proven strategies.
RESUMEN
We sought to establish if smokers on anti-tuberculosis treatment are more likely to have a prolonged period of infectivity, compared to non-smoking tuberculosis patients, in a low tuberculosis prevalence country. We conducted a cross-sectional, retrospective study in Ireland that recruited 53 microbiologically confirmed cases of pulmonary tuberculosis (PTB). The age-sex adjusted odds ratios (AOR) suggest that the infectivity status of PTB on treatment was four times more likely to be prolonged beyond 6-8 weeks, if the cases had a smoking history (AOR: 4.42; 95% CI: 1.23; 15.9). Smoking was associated with delayed sputum smear conversion in PTB patients on treatment.

OBJECTIVES: To examine changes in self-reported arthritis-related illness and self-rated health as a result of a health education intervention, and the association between self-reported arthritis-related illness and self-rated health. STUDY DESIGN: A quasi-experimental study was conducted in eight randomly selected villages in rural Bangladesh (intervention = 4; control = 4). METHODS: The intervention consisted of home-based physical activities, health advice and aspects of healthcare management over 15 months followed by a 3-month latent period. Data were collected before the intervention and after the latent period. Analyses included 839 participants (≥60 years of age) who participated in both surveys. Participants in the intervention area were further categorized into two groups who self-reported compliance or non-compliance with recommended health advice. Self-rated health was assessed using a single global question. Self-reported arthritis-related illness was indicated by the presence of arthritis, back and joint pain, biting sensation, swelling and inflammation in the joints. RESULTS: Hierarchical logistic regression analyses revealed that positive effects on episodes of arthritis-related illness [odds ratio (OR) 1.9, 95% confidence interval (CI) 1.3-2.8] and self-rated health (OR 1.4, 95% CI 1.0-1.9) were more likely among the compliant group compared with the control group. Furthermore, positive self-rated health was more likely among participants reporting a positive change in their arthritis-related illness (OR 2.2, 95% CI 1.5-3.2). The results also showed that literate and non-poor participants were more likely to report positive health, and participants with advancing age were less likely to report positive health. CONCLUSION: Community-based health education is effective in reducing the burden of arthritis-related illness and in enhancing general health in old age.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) causes a huge economic burden and >80% of COPD cases are attributable to smoking. Massachusetts introduced a comprehensive Tobacco Control Program (MTCP) in January 1993. A trend analysis of COPD hospitalization rates might indirectly reflect the potential impact of such comprehensive tobacco control programs. METHODS: Age-adjusted COPD hospitalization rates/100,000 was abstracted from the Massachusetts Community Health Information Profile Database between 1989 and 2005. Joinpoint Regression Analyses program was employed to estimate annual percent changes (APC) in COPD rates by age, sex and race. RESULTS: In 1989, 265/100,000 age-adjusted COPD hospitalization rates were reported that increased to 423/100,000 in 1993, and then declined to 329/100,000 in 2005. A significant annual decline of 5.6 percentage points was observed in overall COPD rates from 1993 onwards. A similar temporal pattern, with an age-gradient and a slower annual decline in female COPD rates relative to male COPD rates, was observed. COPD rates in both Blacks and Whites were similar to the general overall pattern. Such consistent annual declines in COPD hospitalization rates from 1993 onwards in Massachusetts also closely correspond to the introduction of the MTCP in January 1993. CONCLUSION: The findings indirectly suggest that smoking cessation should remain the cornerstone strategy for the prevention and control of COPD burden. However, additional studies across different population settings are essential for a definitive conclusion with regard to the immediate impact of a comprehensive tobacco control program on COPD hospitalization rates showing possible gender susceptibility.

BACKGROUND: A review of smoking cessation (SC) services in Ireland is a necessary step in improving service planning and provision. AIMS: To assess the range and availability of intensive SC services in Ireland in 2006. METHODS: A survey of SC service providers in Ireland was conducted. Descriptive analysis and simple linear regression analysis were used. RESULTS: Response rate was 86.3% (63/73). All service providers surveyed are employing evidence-based interventions; the most common form of support is individual counselling with initial sessions averaging 40 min and weekly review sessions 20 min in duration. Reaching the recommended target of treating 5.0% of smokers does not seem feasible given the current distribution of resources and there appears to be regional differences in resource allocation. CONCLUSIONS: While intensive SC services are available in all four Health Service Executive Areas, it would appear that there is little uniformity or consistency countrywide in the scope and structure of these services.

OBJECTIVE: We hypothesized that smoking rates among the Gay and Lesbian Community (GLC) in Ireland are not significantly different from the general Irish population. METHODS: A convenience sampling of self-identified GLC was recruited using electronic (n = 700) and print (n = 500) media procedures in response to survey call advertisements (December 2006-March 2007). In all, 1,113 had complete smoking data and were analyzed. Data on a random sample of 4,000 individuals, using the Irish Office of Tobacco Control monthly telephone survey, were analyzed for the same period. RESULTS: Adjusted smoking rates in GLC were 26 and 24.6% in the general Irish population (P = 0.99), while "heavy" (> or =20 cigarettes/day) smoking prevalence was 44.1 and 36.6%, respectively (P = 0.02). Upper SES GLCs are "heavy" smokers compared with general population of similar SES group (P = 0.01). CONCLUSION: When considering two different sampling methodologies, this study suggests that smoking rates among the GLC in Ireland are not significantly different from the general Irish population.

OBJECTIVE: This study hypothesised a continual decline in current smoking prevalence over four calendar years (1995, 1998, 2002/03 and 2007) and no significant increase in second-hand-smoke (SHS) exposure levels at home after the workplace smoking ban of March 2004 (2007 versus 2002/03 survey) among Irish school children. METHODS: A modified ISAAC (International Study of Asthma and Allergies in Childhood) protocol was used. Children aged 13-14 years from randomly selected representative post-primary schools were studied: 2670 in 1995, 2273 in 1998, 2892 in 2002-2003, and 2805 in 2007. ISAAC is a cross-sectional self-administered questionnaire survey. Smoking history was self-reported. beta Coefficients (slopes) of smoking rates across the four surveys were computed. Odds ratios for smoking rates were also computed using the baseline year (1995) as the reference period. All analyses were performed using SAS software (v 9.1). RESULTS: There were significant reductions in active smoking rates between 1995 and 2007 (from 19.9% to 10.6%, respectively) resulting in 3.3% survey-to-survey reductions, with a significantly greater survey-to-survey decline among girls compared to boys (3.8% vs 2.7%, respectively). 45% of children were exposed to SHS at home in 2007. There was a statistically non-significant 2% overall decline in SHS exposure levels at home in 2007 relative to 2002/03, which was more pronounced in girls. CONCLUSIONS: The continual reduction in active smoking prevalence in children is welcome. That there was no significant increase in SHS exposure at home after the nationwide workplace smoking ban suggests that the ban did not increase smoking inside homes.

OBJECTIVE: It is well-established that maternal smoking has adverse birth outcomes (low birthweight, LBW, and preterm births). The comprehensive Irish workplace smoking ban was successfully introduced in March 2004. We examined LBW and preterm birth rates 1 year before and after the workplace smoking ban in Dublin. DESIGN: A cross-sectional observational study analysing routinely collected data using the Euroking K2 maternity system. SETTING: Coombe University Maternal Hospital. POPULATION: Only singleton live births were included for analyses (7593 and 7648, in 2003 and 2005, respectively). METHODS: Detailed gestational and clinical characteristics were collected and analysed using multivariable logistic regression analyses and subgroup analyses. MAIN OUTCOME MEASURES: Maternal smoking rates, mean birthweights, and adjusted odds ratios (ORs) of LBW and preterm births in 2005 versus 2003. RESULTS: There was a 25% decreased risk of preterm births (OR, 0.75; 95% CI, 0.59-0.96), a 43% increased risk of LBW (OR, 1.43; 95% CI, 1.10-1.85), and a 12% fall in maternal smoking rates (from 23.4 to 20.6%) in 2005 relative to 2003. Such patterns were significantly maintained when specific subgroups were also analysed. Mean birthweights decreased in 2005, but were not significant (P=0.99). There was a marginal increase in smoking cessation before pregnancy in 2005 (P=0.047). CONCLUSIONS: Significant declines in preterm births and in maternal smoking rates after the smoking ban are welcome signs. However, the increased LBW birth risks might reflect a secular trend, as observed in many industrialised nations, and merits further investigations.

We examined potential associations of ever asthma, and symptoms of wheeze (past 12 months), hay fever, eczema and bronchitis (cough with phlegm) among school children exposed to second-hand smoke (SHS) in cars, using a modified Irish International Study of Asthma and Allergies in Childhood (ISAAC) protocol. 2,809 children of 13-14 yrs old and who selected randomly from post-primary schools throughout Ireland completed the 2007 ISAAC self-administered questionnaire. Adjusted OR (adjusted for sex, active smoking status of children interviewed and their SHS exposure at home) were estimated for the associations studied, using multivariable logistic regression techniques. Overall, 14.8% (13.9% in young males, 15.4% in young females) of Irish children aged 13-14 yrs old were exposed to SHS in cars. Although there was a tendency towards increased likelihood of both respiratory and allergic symptoms with SHS exposure in cars, wheeze and hay fever symptoms were significantly higher (adjusted OR 1.35 (95% CI 1.08-1.70) and 1.30 (1.01-1.67), respectively), while bronchitis symptoms and asthma were not significant (1.33 (0.92-1.95) and 1.07 (0.81-1.42), respectively). Approximately one in seven Irish schoolchildren are exposed to SHS in cars and could have adverse respiratory health effects. Further studies are imperative to explore such associations across different population settings.

This study examines the impact of health education on prevalence of and expenditure on treatment of self-reported arthritis-related illness among elderly persons in rural Bangladesh. An intervention study was conducted, including 1135 elderly persons (>or=60 years) from eight randomly selected villages, four each of an intervention and a control area. The analyses include 839 elderly persons who participated in both pre- and post-intervention surveys (intervention area: n = 425, control area: n = 414). Participants of the intervention area were further categorized as compliant (n = 315) and non-compliant (n = 110) based on adherence to the intervention instructions. The intervention that lasted for 15 months comprised home-based physical exercise, dietary instructions and other aspects of management. Results show that although there was no significant difference in self-reported arthritis-related illness between the compliant and non-compliant groups at baseline, it was significantly lower in the compliant group (71%) at post-intervention compared with the non-compliant (81%). Related monthly expenditure on treatment was significantly reduced in the compliant group (from Taka 104 to Taka 52) but not in the other two groups. Logistic regressions further showed that the control group had a higher probability of increased treatment-related expenditure compared with the compliant group (OR 2.0, 95% CI 1.4-2.8).

In 1990, the sale, marketing and distribution of bituminous coal, primarily used for domestic heating, were banned across Dublin. This study exploits the potential of a 'natural experiment' to assess a temporal association between adjusted annual lung cancer death rates and the changing annual mean urban air-pollution concentrations in Dublin from 1981 to 2000. Annual mean 'black smoke' (BS) concentration was used as an indicator variable for the urban air-pollution mixture. Log-linear Poisson regression model (with an offset) was used to estimate adjusted rate ratios of lung cancer death rates between two periods (1981-1990 and 1991-2000) relative to the year 1990. A significant (p<0.0001) two-third decline in BS concentration (28.2 microg/m(3)) was seen between the two periods [pre-ban (46.4 microg/m(3)) vs. post-ban (18.2 microg/m(3))]. Relative to 1990 (rate ratio= 1 ), a slightly greater decline (2%) in death rates was achieved in the pre-ban period (1981-1990) when mean annual BS concentrations were very high, but a lower decline (1%) was seen in the post-ban period (1991-2000) corresponding to very low mean annual BS concentrations. In other words, a further fall in adjusted rates in lung cancer was achievable both in the pre-ban and the post-ban periods when simultaneously controlling for BS and smoking. A temporal association thus observed between lung cancer death rates and the changing BS concentrations suggests that control of particulate air-pollution could further reduce lung cancer rates, irrespective of smoking patterns.

BACKGROUND: Distinct temporal patterns can be identified through estimating annual-percent-changes (APC) in age-specific disease rates, but APCs in lung cancer rates among the youngest adults can also reflect the recent changing smoking habits of a population. METHOD: Lung cancer mortality rates from 1970 to 1999 were investigated in Ireland, using the Joinpoint regression modelling technique. RESULTS: In the most recent decade (1989-1999) male lung cancer death rates showed a significant annual decline (-2.4%), but female annual rates have scarcely decelerated (0.1%). The combined gender youngest adults (30-39 year-olds) showed decreasing rates, but the annual decline in the youngest female rates were significant only from 1970 to 1990 and thereafter increased non-significantly. CONCLUSION: Unlike male lung cancer death rates, the overall female rates are increasing significantly. While the combined gender youngest adult rates are decreasing, the apparent reversal in trends among the youngest female rates from 1990 onwards is worrying.
