This leaflet is given to all men who have attended screening through the Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme and been diagnosed with a medium AAA.The leaflet provides: background information on the AAA screening programme; details on what a medium AAA is; information on the monitoring process to regularly check the size of the AAA;lifestyle advice that may help those men diagnosed with an AAA. Men who have been diagnosed with a medium AAA will be invited to a monitoring scan once every three months, unless their AAA increases in size to a large AAA, at which point they will be referred to a team of vascular specialists for further assessment and the possible offer of surgery.

Your result shows a large abdominal aortic aneurysm (AAA) that may need surgery

This leaflet is given to all men who have attended screening through the Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme and been diagnosed with a large AAA.The leaflet provides: background information on the AAA screening programme; details on what a large AAA is; information on the process of referral to a team of vascular specialists;details on the operation to treat a large AAA;important information on the symptoms of a ruptured AAA;lifestyle advice that may help those men diagnosed with an AAA. Men who have been diagnosed with a large AAA will be invited to meet a team of vascular specialists for further assessment within two or three weeks of their scan. Following additional medical tests, the patient may be offered surgery to treat the large AAA. Those men assessed as unsuitable for an operation will continue to be monitored within the vascular service.

Northern Ireland AAA Screening Programme: Professional information pack

The Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme began in June 2012 and offers AAA screening to all men in their 65th year in Northern Ireland.The aim of the AAA screening programme is to reduce AAA-related mortality by providing systematic, population-based screening. There is evidence of a significant reduction (45%) in mortality from AAA in those men aged between 65 and 79 years who undergo ultrasound screening. Men older than 65 years will be able to opt into the programme and request screening through the central screening office.There is also evidence of the long-term cost-effectiveness of AAA screening in men and further evidence that the early mortality benefit from screening is maintained.The items available for download here were in the professional information pack that was sent out to all GPs, GP practice managers and pharmacies prior to the launch of the programme.The invitation leaflet is sent out to all eligible men with the letter inviting them to screening.�The results leaflets are for men diagnosed with a small, medium or large AAA. The relevant result leaflet is given to men directly after their scan.�The poster was sent out to all GPs, GP practice managers and pharmacies in the run-up to the launch of the programme as a means of raising awareness.The information sheet outlines the structure of the programme, the screening process and the primary care that follows for those men diagnosed with an AAA. It also highlights the risk factors and has stats on AAA prevalence.The frequently asked questions address issues relating to all aspects of the programme: what is an AAA, roll-out of the programme, the screening process, the scan itself, the possible results, the available treatment, and how personal information is used.

Abdominal Aortic Aneurysm (AAA) Screening Programme annual report

This inaugural annual report for the Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme (produced jointly by the Public Health Agency and the Belfast Health and Social Care Trust) looks back on a successful first year for the programme. The Public Health Agency (PHA) is responsible for commissioning and quality assuring the programme. The Belfast Health and Social Care Trust is responsible for providing and managing the programme.Following significant planning, AAA screening was introduced on time in June 2012, as required by the Government's 'Priorities for Action' target. There is no doubt that this was due to sustained partnership working across a wide range of health and social care services within Northern Ireland.

Abdominal aortic aneurysm (AAA) screening: Things you need to know (English and translations)

This information leaflet is for all men invited to take part in the Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme. Men will automatically be invited for screening in their 65th year, while men aged over 65 can request a scan through the central screening office.

AVALIAÇÃO DE UM PROTOCOLO PARA MULTIPLICAÇÃO IN VITRO DA BANANEIRA (Musa sp.) CV. CAIPIRA (AAA)

Explantes de bananeira cv. Caipiras (AAA) foram cultivados in vitro. Nas subculturas de estabelecimento e multiplicação, o meio utilizado foi MS + 5 mg/l de BAP e, na de enraizamento, 50%MS sem BAP. Na avaliação das subculturas, a maior contaminação ocorreu no estabelecimento (74,7%), seguindo decrescente até o enraizamento, com 5,6%. O número de brotos por frasco diminui ao longo das subculturas, atingindo 3,7 brotos na subculturas 1 e 1,7 na subcultura 4. O tamanho dos brotos permaneceu entre 24 e 26 mm, nas subculturas de 1 a 3, diminuindo na subcultura 4, com 22 mm. Como conseqüência, a classe de brotos menores (x £ 20 mm) predominou, variando de 56% na subcultura 1 para 65% na subcultura 4. No enraizamento, a predominância (62%) foi de brotos na faixa entre 30 e 60 mm, com média de 4,6 brotos por frasco. A avaliação geral do processo indicou um rendimento real de 70,9 mudas/rizoma.

Efeito da interação entre carvão ativado e N6-benzilaminopurina na propagação in vitro de bananeira, cv. Grand Naine (AAA)

O carvão ativado possui a propriedade de adsorver os compostos fenólicos liberados pela oxidação dos tecidos lesionados durante o cultivo in vitro. O objetivo deste trabalho foi avaliar os efeitos da interação entre o carvão ativado e diferentes concentrações de N6-benzilaminopurina (BAP) na multiplicação in vitro da bananeira, cv. Grande Naine (AAA). O meio de cultura utilizado foi o MS, solidificado com 5 g.L-1 de ágar. O cultivo foi mantido em sala de crescimento a 25±2ºC, fotoperíodo de 16 horas e intensidade luminosa de 30 mmol.m-2s-1. Foram avaliadas a presença e a ausência de carvão ativado (0 e 3 g.L-1) e quatro concentrações de BAP (0; 2; 4 e 6 mg.L-1) no meio de cultura. O delineamento foi inteiramente casualizado, com cinco repetições, em um sistema fatorial 2x4. Os explantes foram avaliados a cada 30 dias, por um período de quatro subcultivos. Após cada subcultivo, o comprimento de brotações, a taxa de multiplicação, o vigor, o nível de oxidação das brotações emitidas e o número de raízes formadas foram avaliados. Independentemente das concentrações de BAP, o carvão ativado influenciou significativamente em todas as variáveis analisadas. De maneira geral, a adição de carvão ativado afetou negativamente a taxa de multiplicação, embora tenha melhorado o vigor e o número de raízes e diminuído a oxidação dos explantes. Na ausência de carvão ativado, o BAP proporcionou as maiores taxas de multiplicação das brotações.

Influencia de la pérdida foliar sobre la cosecha en el cv. Gruesa, Musa acuminata Colla (AAA), cultivado bajo invernadero en las Islas Canarias

El cultivo de la variedad de platanera Gruesa, selección local de Dwarf Cavendish, ha experimentado un importante aumento en los últimos años en las Islas Canarias, tanto al aire libre como bajo invernadero. La eliminación de hojas, tras la floración, es una práctica habitual en los cultivos bajo invernadero. Asimismo es frecuente la pérdida de hojas por el efecto de los vientos en los cultivos al aire libre. El objetivo de este trabajo es evaluar, mediante simulación de pérdida foliar por daños mecánicos, la influencia que tiene la disminución de superficie foliar sobre el llenado y cosecha de la fruta en dicho cultivar. Para ello, cuatro meses antes de la cosecha se efectuaron cinco niveles de defoliación: 0%, 25%, 50%, 75% y 100%. Se valoran dos métodos diferentes de defoliación, eliminación de limbo foliar y tronchado de hojas con posterior corte de éstas. Se analizan y presentan datos morfológicos, fenológicos y productivos, así como valoración de la metodología empleada en este trabajo para la simulación de daños. A partir de un 25% de defoliado, equivalente a 7.5 hojas funcionales por planta, se detectaron diferencias significativas con las plantas testigos.

Histological changes in banana explants, cv. Nanicão (Musa spp., Group AAA), submitted to different auxins for induction of somatic embryogenesis

The present work analyzes the behavior of banana explants, cv. Nanicão (Musa spp. Group AAA) regarding somatic embryogenesis induction treatments with several auxins. Longitudinal segments of shoot meristematic apices of micropropagated banana plantlets cultivated and rooted in vitro were introduced in culture medium containing dicamba, picloram, 2,4-D or NAA in different concentrations. Explant samples were collected at 0, 7 and 10 days and prepared for light microscopy. Histological sections were used for comparison of the histological changes occurring after induction treatment with different auxins. Embryogenic response was observed only in treatments with picloram or dicamba, with distinct embryogenic regions observed at 14 and 21 days in culture, respectively. Histological sections of embryogenic regions of the explant at 26 days in culture revealed the formation of meristematic regions, structures with multiple root meristems, and somatic embryos at early globular stages. Embryo-like structures morphologically similar to Musa balbisiana zygotic embryos were sectioned and showed a lack of apical meristems and absence of procambial differentiation. These results indicate the induction of non-functional somatic embryos and the need for more studies on developmental aspects and maturation treatments for optimization of the process.
