IPH Response to draft Northern Ireland Programme for Government 2011-15

On 17 November 2011, the First Minister and deputy First Minister published the draft Programme for Government 2011-2015 for consultation. IPH recognise that health is influenced by a wide range of social determinants, including economic, biological, environmental and cultural factors such as housing, the environment, income, employment and access to education and health services . Improvements to health can be achieved through a well-designed PfG which addresses the economy, creates safer communities and delivers efficient public services.  IPH welcome this opportunity to submit our views to the Northern Ireland Executive on the Draft Programme for Government 2011-15. Key points from the IPH response include: • Northern Ireland has a poor population health status in key areas when compared to other regions in the United Kingdom and in the Republic of Ireland. IPH support and particularly welcome allocation of an increased proportion of the Northern Ireland budget to public health. • IPH endorses the perspective in the PfG that good population health makes a central contribution to economic and social development.   However we would welcome greater acknowledgement of the links between social deprivation and health outcomes.  • IPH welcomes the adoption of a social determinants of health approach to improving population health and tackling health inequalities which is in line with current health policy and recent policy developments across the United Kingdom and internationally (See report of the Commission on the Social Determinants of Health (CSDH))

Etiology of first-ever ischaemic stroke in European young adults: the 15 cities young stroke study.

BACKGROUND AND PURPOSE: Risk factors for IS in young adults differ between genders and evolve with age, but data on the age- and gender-specific differences by stroke etiology are scare. These features were compared based on individual patient data from 15 European stroke centers. METHODS: Stroke etiology was reported in detail for 3331 patients aged 15-49 years with first-ever IS according to Trial of Org in Acute Stroke Treatment (TOAST) criteria: large-artery atherosclerosis (LAA), cardioembolism (CE), small-vessel occlusion (SVO), other determined etiology, or undetermined etiology. CE was categorized into low- and high-risk sources. Other determined group was divided into dissection and other non-dissection causes. Comparisons were done using logistic regression, adjusting for age, gender, and center heterogeneity. RESULTS: Etiology remained undetermined in 39.6%. Other determined etiology was found in 21.6%, CE in 17.3%, SVO in 12.2%, and LAA in 9.3%. Other determined etiology was more common in females and younger patients, with cervical artery dissection being the single most common etiology (12.8%). CE was more common in younger patients. Within CE, the most frequent high-risk sources were atrial fibrillation/flutter (15.1%) and cardiomyopathy (11.5%). LAA, high-risk sources of CE, and SVO were more common in males. LAA and SVO showed an increasing frequency with age. No significant etiologic distribution differences were found amongst southern, central, or northern Europe. CONCLUSIONS: The etiology of IS in young adults has clear gender-specific patterns that change with age. A notable portion of these patients remains without an evident stroke mechanism according to TOAST criteria.

Sexual Offending in Northern Ireland - Managing the Risk 2001-2005

An examination of male and female odds ratios by BMI, cigarette smoking, and alcohol consumption for cancers of the oral cavity, pharynx, and larynx in pooled data from 15 case-control studies.

BACKGROUND: Greater tobacco smoking and alcohol consumption and lower body mass index (BMI) increase odds ratios (OR) for oral cavity, oropharyngeal, hypopharyngeal, and laryngeal cancers; however, there are no comprehensive sex-specific comparisons of ORs for these factors. METHODS: We analyzed 2,441 oral cavity (925 women and 1,516 men), 2,297 oropharynx (564 women and 1,733 men), 508 hypopharynx (96 women and 412 men), and 1,740 larynx (237 women and 1,503 men) cases from the INHANCE consortium of 15 head and neck cancer case-control studies. Controls numbered from 7,604 to 13,829 subjects, depending on analysis. Analyses fitted linear-exponential excess ORs models. RESULTS: ORs were increased in underweight (<18.5 BMI) relative to normal weight (18.5-24.9) and reduced in overweight and obese categories (>/=25 BMI) for all sites and were homogeneous by sex. ORs by smoking and drinking in women compared with men were significantly greater for oropharyngeal cancer (p < 0.01 for both factors), suggestive for hypopharyngeal cancer (p = 0.05 and p = 0.06, respectively), but homogeneous for oral cavity (p = 0.56 and p = 0.64) and laryngeal (p = 0.18 and p = 0.72) cancers. CONCLUSIONS: The extent that OR modifications of smoking and drinking by sex for oropharyngeal and, possibly, hypopharyngeal cancers represent true associations, or derive from unmeasured confounders or unobserved sex-related disease subtypes (e.g., human papillomavirus-positive oropharyngeal cancer) remains to be clarified.

Deltamethrin-impregnated dog collars have a potent anti-feeding and insecticidal effect on Lutzomyia longipalpis and Lutzomyia migonei

Deltamethrin-impregnated PVC dog collars were tested to assess if they were effective in protecting dogs from sand fly bites of Lutzomyia longipalpis and Lu. migonei. A protective effect against Old World species Phlebotomus perniciosus was demonstrated before. Four dogs wearing deltamethrin collars and three dogs wearing untreated collars (not impregnated with deltamethrin) were kept in separate kennels for over eight months in a village on the outskirts of Fortaleza in Ceará, Brazil. Periodically, a dog from each group was sedated, placed in a net cage for 2 h in which 150 female sand flies had been released 10-15 min before. Lu. longipalpis were used 4, 8, 12, 16, 22, 27, and 35 weeks after the attachment of the collars. Lu. migonei were used 3, 7, 11, 15, 22, 26, and 36 weeks after attachment. During 35 weeks, only 4.1% (81 of 2,022) Lu. longipalpis recovered from the nets with the deltamethrin collared dogs were engorged, an anti-feeding effect of 96%. Mortality initially was over 90% and at 35 weeks was 35% with half of the sand flies dying in the first 2 h. In contrast, 83% of the 2,094 Lu. longipalpis recovered from the nets containing the untreated collared dogs were engorged and the mortality ranged from zero to 18.8% on one occasion with 1.1% dying in the first 2 h. Similar findings were found with Lu. migonei: of 2,034 sand flies recovered over this period, only 70 were engorged, an anti-feeding effect of 96.5%, and mortality ranged from 91% initially to 46% at 36 weeks. In contrast, engorgement of controls ranged from 91 to71% and a mortality ranged from 3.5 to 29.8%. These studies show that deltamethrin impregnated collars can protect dogs against Brazilian sand flies for up to eight months. Thus, they should be useful in a program to control human and canine visceral leishmaniasis.

Granulomatosis de Wegener: estudio de 15 casos, supervivencia y daño crónico

La granulomatosi de Wegener i la síndrome de Churg-Strauss són vasculitis granulomatoses de petit i mitjà vas. Es diagnostiquen mitjançant clínica i biòpsia compatible, i s'associen amb anticossos anticitoplasma de neutròfils. S'ha realitzat un estudi retrospectiu (1984 - 2010) a l'Hospital Universitari Germans Trias i Pujol. Es presenten 15 pacients amb granulomatosi de Wegener. Les característiques clíniques de la present sèrie no difereixen de les descrites prèviament. Es va comparar la supervivència i el dany crònic acumulat en els pacients amb aquestes dues vasculitis. Tant la mortalitat com el dany crònic acumulat resultà superior en el grup de malalts amb granulomatosi de Wegener.

Altered Response of Strain of Schistosoma mansoni to Oxamniquine and Praziquantel

The susceptibility of a fourth generation Ouh strain (Paranapanema Valley, São Paulo, Brazil) of Schistosoma mansoni to oxamniquine (OXA) and praziquantel (PZQ) was studied. Ten groups of 13 female albino mice each were infected with 70 cercariae per animal. These mice were medicated orally on the 50th day after infection. Five groups were given OXA doses of 0, 100, 200, 300 and 400 mg/kg (single doses) and the rest were treated with PZQ doses of 0, 100, 200, and 250 mg/kg/5 days. Each group was sub-divided: 8 animals underwent perfusion after 15 days treatment, 5 mice followed up for oviposition and their feces were tested every 15 days for miracidia hatching. The efficacy of the OXA doses of 100 and 200 mg/kg was 66% and 91.4%, respectively and for the 100 mg/kg PZQ dose it was 90.1%. The follow-up groups with 100 and 200 mg/kg of OXA and PZQ, 100 and 150 mg/kg, showed that they re-established the oviposition after a period of 60 to 75 days of treatment. The ED50 was 69.6mg/kg OXA and 39.4 mg/kg PZQ. The results show the tolerance of the Ouh strain to a dose of 100 mg with both drugs and they appoint the need for a dose review during the follow up of the oviposition and in monitoring phenomena in the field.

In situ stromal expression of the urokinase/plasmin system correlates with epithelial dysplasia in colorectal adenomas.

An increase of urokinase-type plasminogen activator (uPA) and a decrease of tissue-type PA (tPA) have been associated with the transition from normal to adenomatous colorectal mucosa. Serial sections from 25 adenomas were used to identify PA-related caseinolytic activities by in situ zymography, blocking selectively uPA or tPA. The distribution of uPA, tPA, and type 1 PA inhibitor mRNAs was investigated by nonradioactive in situ hybridization, and the receptor for uPA was detected by immunostaining. Low- and high-grade epithelial cell dysplasia was mapped histologically. Results show that 23 of 25 adenomas expressed uPA-related lytic activity located predominantly in the periphery whereas tPA-related activity was mainly in central areas of adenomas. In 15 of 25 adenomas, uPA mRNA was expressed in stromal cells clustered in foci that coincided with areas of uPA lytic activity. The probability of finding uPA mRNA-reactive cells was significantly higher in areas with high-grade epithelial dysplasia. uPA receptor was mainly stromal and expressed at the periphery. Type 1 PA inhibitor mRNA cellular expression was diffuse in the stroma, in endothelial cells, and in a subpopulation of alpha-smooth muscle cell actin-reactive cells. These results show that a stromal up-regulation of the uPA/plasmin system is associated with foci of severe dysplasia in a subset of colorectal adenomas.

Laparoscopic Roux-en-Y gastric bypass: initial 2-year experience.

BACKGROUND: Roux-en-Y gastric bypass (RYGBP)-essentially a restrictive bariatric procedure-is currently considered the gold standard for the surgical treatment of morbid obesity. Open surgery in obese patients is associated with a high risk of cardiopulmonary complications, wound infection, and late incisional hernia. Laparoscopic surgery has been shown to reduce perioperative morbidity and to improve postoperative recovery for various procedures. Herein we present our results with laparoscopic RYGBP after an initial 2-year experience. METHODS: A prospective database was created in our department beginning without the first laparoscopic bariatric procedure. To provide a complete follow-up of 6 months, the results of all patients operated on between June 1999 and August 2001 were reviewed. Early surgical results, weight loss, correction of comorbidities, and improvement of quality of life were evaluated. RESULTS: A total of 107 patients were included. There were 82 women and 25 men, with a mean age of 39.7 years (range, 19-58). RYGBP was a primary procedure in 80 cases (49 morbidly obese and 31 superobese patients) and a reoperation after failure or complication of another bariatric operation in 27 cases. Mean duration of surgery was 168 min for morbidly obese patients, 196 min for surperobese patients, and 205 min for reoperated patients (p <0.01). Conversion to open surgery was necessary in two cases. A total of 22 patients (20.5%) developed complication. Nine of them (8.4%) required reoperation for leak (five cases, or 4.6%), bowel occlusion (three cases, or 2.8%), or subphrenic abscess (one case, or 0.9%). mortality was 0.9%. Major morbidity decreased over time (first two-thirds, 12.5%, last third, 2.7%). major morbidity decreased over time (first two-thirds, 12.5%; last third, 2.7%). Excess weight loss of -50% was achieved in >80% of the patients, corresponding to a loss of 15 body mass index (BMI) units in morbidly obese patients and 20 BMI units in superobese patients. In the vast majority of patients, comorbidities improved or disappeared over time and quality of life improved. CONCLUSIONS: Laparoscopic Roux-en-Y gastric bypass is feasible, but it is a very complex operation. Indeed, it is associated with a long and steep learning curve, as reflected in the high number of major complications among our first 70 patients. The learning curve probably includes between 100 and 150 patients. With increasing experience, the morbidity rate becomes more acceptable and comparable to that of open RYGBP. The results in terms of weight loss and correction of comorbidities are similar to those obtained after open surgery, at least in the short term. However, only surgeons with extensive experience in advanced laparoscopic as well as bariatric surgery should attempt this procedure.
