Determinants of Human Immunodeficiency Virus (HIV) prevalence in homosexual and bisexual men screened for admission to a cohort study of HIV negatives in Belo Horizonte, Brazil: Project Horizonte

Project Horizonte, an open cohort of homosexual and bisexual human immunodeficiency virus (HIV-1) negative men, is a component of the AIDS Vaccine Program, in Belo Horizonte, Minas Gerais, Brazil. The objective of this study was to compare volunteers testing HIV positive at cohort entry with a sample of those who tested HIV negative in order to identify risk factors for prevalent HIV infection, in a population being screened for enrollment at Project Horizonte. A nested case-control study was conducted. HIV positive volunteers at entry (cases) were matched by age and admission date to three HIV negative controls each. Selected variables used for the current analysis included demographic factors, sexual behavior and other risk factors for HIV infection. During the study period (1994-2001), among the 621 volunteers screened, 61 tested positive for HIV. Cases were matched to 183 HIV negative control subjects. After adjustments, the main risk factors associated with HIV infection were unprotected sex with an occasional partners, OR = 3.7 (CI 95% 1.3-10.6), receptive anal intercourse with an occasional partner, OR = 2.8 (95% CI 0.9-8.9) and belonging to the negro racial group, OR = 3.4 (CI 95% 1.1-11.9). These variables were associated with an increase in the risk of HIV infection among men who have sex with men at the screening for admission to an open HIV negative cohort.

Towards standardization of UV eye protection: what can be learned from photodermatology?

While knowledge about standardization of skin protection against ultraviolet radiation (UVR) has progressed over the past few decades, there is no uniform and generally accepted standardized measurement for UV eye protection. The literature provides solid evidence that UV can induce considerable damage to structures of the eye. As well as damaging the eyelids and periorbital skin, chronic UV exposure may also affect the conjunctiva and lens. Clinically, this damage can manifest as skin cancer and premature skin ageing as well as the development of pterygia and premature cortical cataracts. Modern eye protection, used daily, offers the opportunity to prevent these adverse sequelae of lifelong UV exposure. A standardized, reliable and comprehensive label for consumers and professionals is currently lacking. In this review we (i) summarize the existing literature about UV radiation-induced damage to the eye and surrounding skin; (ii) review the recent technological advances in UV protection by means of lenses; (iii) review the definition of the Eye-Sun Protection Factor (E-SPF®), which describes the intrinsic UV protection properties of lenses and lens coating materials based on their capacity to absorb or reflect UV radiation; and (iv) propose a strategy for establishing the biological relevance of the E-SPF.

Health and wellbeing project

This project will promote and introduce a healthier lifestyle for people over 50 through healthy eating, exercise and self-help in the Atticall and surrounding area. The project will focus on local produce and give participants an opportunity to cook and taste samples of their own 'healthy food'. The Pharmacist will attend these sessions to give diet realted talks and anwer any queries people may have.

Belcoo green gym project

The aim is to work with children as a means to communicating to family and friends. The practical side of the project will take local children out of the classroom surrounding and into the natural environment. The children involved will participate in growing their own fruit and vegetable garden and learn the importance of healthy diet alongside other key stage development issues such as recycling and food chains.

Larne Community Development Project

This partnership has been funded a couple of times to mainly looking at supporting women to look at health issues in the area. This project has, to date, worked well in making community development and health real. It has helped establish a women's group in the area and has enabled women to bring back relevant information to their families, friends, communities and other local groups they have been involved in. The pharmacy and pharmacist have been a key catalyst for this making use of skills, knowledge, contacts and premises. Some initial work was also carried out with men in the area, encouraging them to consider their health. This Level 3 project now goes a step further; skilling the women, as facilitators, to enable them to role out the information they have gained in a more formal way to the Larne area and its surrounding rural area. It also allows space and time for those women, not at this stage, to gain information, skills and confidence to take back to their families and friends. It also seeks to develop an approach targeting towards encouraging men to think about their health.

Sistema per protegir la privadesa dels usuaris dels motors de cerca d'Internet

Actualment seria impensable la existència d'una xarxa d'informació com Internet sense la existència dels motors de cerca. Gràcies a ells, qualsevol usuari tenim al nostre abast la possibilitat d'obtenir informació sobre qualsevol tema només enviant una consulta des dels nostres ordinadors i rebent una resposta en qüestió de segons. Entre els usuaris dels cercadors d'Internet és molt habitual que les consultes facin referència a la empresa on treballem, la ciutat on vivim, els llocs que visitem, o inclús sobre problemes que tenim o malalties que patim amb l'objectiu de trobar opinions, consells o solucions. En resum, els usuaris, a través de les nostres consultes, proporcionem a diari als motors de cerca informació sobre nosaltres mateixos i sobre la nostra identitat que, juntament amb la adreça IP de la màquina des d'on fem les nostres consultes, ens fa perdre l'anonimat dins dels seus sistemes. Sobre aquesta problemàtica és del que tracta el present Projecte de Final de Carrera. En ell s'ha implementat una solució de la proposta especificada per Alexandre Viejo i Jordi Castellà-Roca en la seva publicació "Using social networks to disort users' profiles generated by web search engines", en la qual es documenten una sèrie de protocols de seguretat i d'algorismes de protecció i distribució que garanteixen la privacitat de la identitat dels usuaris dins dels motors de cerca aprofitant per aquest fi la relació existent entre aquests usuaris a través de les xarxes socials.

Cook it! An evaluation of a community nutrition education programme in Northern Ireland

Cook it! was originally introduced to Northern Ireland in 1995 by the Health Promotion Agency for Northern Ireland (HPA) in a collaborative project with the Eastern Health and Social Services Board, the Northern Health and Social Services Board and the North and West Belfast Health and Social Services Trust. Having run for five years, this initial phase of the programme was evaluated in 2000. Cook it! was found to be a valuable approach to community based nutrition education. However, a number of recommendations were made as to how it could be improved. In conjunction with a number of community dietitians the HPA therefore revised and updated the programme, which included a redesigned resource manual with improved session outlines and recipe sheets. The Public Health Agency was established in 2009 under a major reform ofhealth structuresin Northern Ireland. The four key functions of the PHA are: health and social wellbeing improvement; health protection; public health support to commissioning and policy development; HSC research and development.

Maternal Obesity in the UK: Findings from a national project

In 2008, the Confidential Enquiry into Maternal and Child Health (CEMACH), now known as the Centre for Maternal and Child Enquiries (CMACE), commenced a 3-year UK-wide Obesity in Pregnancy project. The project was initiated in response to a number of factors. At the time, these included: i) growing evidence that obesity is associated with increased morbidity and mortality for both mother and baby, ii) evidence from the CEMACH 'Saving Mothers' Lives' report showed that women with obesity were over-represented among those who died of direct deaths compared to those who died of indirect deaths, 1 iii) unknown national and regional prevalence rates of maternal obesity, and iv) the need for a national clinical guideline for the care of women with obesity in pregnancy.

Survival responses in stressed organs

Apoptosis or programmed cell death is a regulated form of cell suicide executed by cysteine proteases, or "caspases", to maintain proper tissue homeostasis in multicellular organisms. Dysregulation of apoptosis leads to pathological complications including cancer, autoimmunity, neurodegenerative, and heart diseases. Beside their known function as the key executioners of apoptotic cell death, caspases were reported to mediate non-apoptotic functions. In this report we study the survival signals conveyed through caspase-3-mediated cleavage of Ras GTPase-activating proteins (RasGAP). Ubiquitously expressed, RasGAP senses caspase activity and controls the cell death/survival switch. RasGAP is cleaved once at low caspase activity and the generated N-terminal fragment (fragment N) induces a survival response by activating Ras/PI3K/Akt pathway. However, high caspase activity associated with increased stress leads to fragment Ν cleavage into fragments that do not mediate any detectable survival signals. In this thesis project we studied the role of fragment Ν in protecting stressed organs as well as in maintenance of their functionality. In response to stress in different organs, we found that mice lacking caspase-3 or unable to cleave RasGAP (Knock-In mice), and therefore unable to generate fragment N, were deficient in Akt activation and experienced increased apoptosis compared to wild-type mice. Augmented tissue damage and organ dysfunction in those mice highlight the importance of fragment Ν in activating Akt-mediated prosurvival pathway and in protection of organs during episodes of stress. In parallel we investigated the role of fragment Ν in regulating the activation of transcription factor NF-kB, a master regulator of inflammation. Sustained NF-kB activation may be detrimental by directly causing apoptosis or leading to a persistent damaging inflammation response. We found that fragment Ν is a potent inhibitor of NF-kB by favoring its nuclear export. Therefore, fragment Ν regulates NF-kB activity and contributes to a controlled response as well as maintenance of homeostasis in stressed cells. Importantly, these findings introduce new insights of how activated caspase-3 acts as a stress intensity sensor that controls cell fate by either initiating a fragment N- dependent cell resistance program or a cell suicide response. This identifies the pivotal role of fragment Ν in protection against patho-physiological damage, and encourages the development of therapies which aim to increase cell resistance to vigorous treatment. - L'apoptose, ou mort cellulaire programmée, est une forme contrôlée de suicide cellulaire exécuté par des protéines appelées caspases, dans le but de maintenir l'homéostasie des tissus sains dans les organismes multicellulaires. Un mauvais contrôle de l'apoptose peut mener à des pathologies comme le cancer, la neurodégénération et les maladies cardiaques et auto-immunes. En dehors de leur rôle connu d'exécutrices de l'apoptose, les caspases ont aussi été identifiées dans d'autres contextes non-apoptotiques. Dans ce projet, nous avons étudié les signaux de survie émis par le résultat du clivage de RasGAP par la caspase-3. Exprimée de façon ubiquitaire, RasGAP est sensible à l'activité de caspase-3 et contrôle la décision de la cellule à entreprendre la mort ou la survie cellulaire. A un taux d'activité faible, la caspase-3 clive RasGAP, ce qui mène à la génération d'un fragment N-terminal, appelé Fragment N, qui induit des signaux de survie via l'activation de la cascade Ras/PI3K/Akt. Cependant, lorsque l'activité de la caspase-3 augmente, le fragment N est clivé, ce qui a pour effet d'éliminer ces signaux de survie. Dans ce travail, nous avons étudié le rôle du Fragment N dans la protection des organes en état de stress et dans le maintien de leur fonctionnalité. En réponse à certains stress, nous avons découvert que les organes de souris n'exprimant pas la caspase-3 ou alors incapables de cliver RasGAP (souris Kl), et de ce fait n'ayant pas la possibilité de générer le Fragment N, perdaient leur faculté d'activer la protéine Akt et démontraient un taux d'apoptose plus élevé que des organes de souris sauvages. Le fait que les organes et tissus de ces souris manifestaient de graves dommages et dysfonctions met en évidence l'importance du Fragment N dans l'activation des signaux de survie via la protéine Akt et dans la neutralisation de l'apoptose induite par la caspase-3. En parallèle, nous avons investigué le rôle du Fragment N dans la régulation de l'activation de NF-kB, un facteur de transcription clé dans l'inflammation. Une activation soutenue de NF-kB peut être délétère par activation directe de l'apoptose ou peut mener à une réponse inflammatoire persistante. Nous avons découvert que le Fragment N, en favorisant l'export de NF-kB depuis le noyau, était capable de l'inhiber très efficacement. Le Fragment N régule donc l'activité de NF-kB et contribue au maintien de l'homéostasie dans des cellules stressées. Ces découvertes aident, de façon importante, à la compréhension de comment l'activation de la caspase-3 agit comme senseur de stress et décide du sort de la cellule soit en initiant une protection par le biais du fragment N, ou en induisant un suicide cellulaire. Cette étude définit le Fragment Ν comme ayant un rôle de pivot dans la protection contre des dommages patho-physiologiques, et ouvre des perspectives de développement de thérapies qui cibleraient à augmenter la résistance à divers traitements.
