The European Cancer Registry-based project on hematologic malignancies (HAEMACARE), set up to improve the availability and standardization of data on hematologic malignancies in Europe, used the European Cancer Registry-based project on survival and care of cancer patients (EUROCARE-4) database to produce a new grouping of hematologic neoplasma(defined by the International Classification of Diseases for Oncology, Third Edition and the 2001/2008 World Health Organization classifications) for epidemiological and public health purposes. We analyzed survival for lymphoid neoplasms in Europe by disease group, comparing survival between different European regions by age and sex. Design and Methods Incident neoplasms recorded between 1995 to 2002 in 48 population-based cancer registries in 20 countries participating in EUROCARE-4 were analyzed. The period approach was used to estimate 5-year relative survival rates for patients diagnosed in 2000-2002, who did not have 5 years of follow up. Results: The 5-year relative survival rate was 57% overall but varied markedly between the defined groups. Variation in survival within the groups was relatively limited across European regions and less than in previous years. Survival differences between men and women were small. The relative survival for patients with all lymphoid neoplasms decreased substantially after the age of 50. The proportion of ‘not otherwise specified’ diagnoses increased with advancing age.Conclusions: This is the first study to analyze survival of patients with lymphoid neoplasms, divided into groups characterized by similar epidemiological and clinical characteristics, providing a benchmark for more detailed analyses. This Europe-wide study suggests that previously noted differences in survival between regions have tended to decrease. The survival of patients with all neoplasms decreased markedly with age, while the proportion of ‘not otherwise specified’ diagnoses increased with advancing age. Thus the quality of diagnostic work-up and care decreased with age, suggesting that older patients may not be receiving optimal treatment

The influence of temperature on the developmental times and survival of insects can largely determine their distribution. For invasive species, like the Argentine ant, Linepithema humile Mayr (Hymenoptera: Formicidae), these data are essential for predicting their potential range based on mechanistic models. In the case of this species, such data are too scarce and incomplete to make accurate predictions based on its physiological needs. This research provides comprehensive new data about brood survival and developmental times at a wide range of temperatures under laboratory conditions. Temperature affected both the complete brood development from egg to adult worker and each of the immature stages separately. The higher the temperature, the shorter the development times. Brood survival from egg to adult was low, with the maximum survival rate being only 16% at 26º C. Temperature also affected survival of each of the immature stages differently: eggs were negatively affected by high temperatures, while larvae were negatively affected by low temperatures, and the survival of pupae was apparently independent of environmental temperature. At 32º C no eggs survived, while at 18º C less than 2% of the eggs hatched into larva. The data from the present study are essential for developing prediction models about the distribution range of this tramp species based on its physiological needs in relation to temperature

Monogamy and sex without penetration are behaviors recommended by the WHO to avoid AIDS virus sexual transmission. Seven hundred and fifty university students from 18 to 25 years (67.7% women) were surveyed and they were asked to give a maximum of three free definitions of the words monogamy and sex without penetration to prevent AIDS virus sexual transmission. Their participation was voluntary and anonymous. Although the majority of the answers was correct, there was a considerable percentage of wrong answers, either for monogamy (3.7% masturbation; 2.1% to have many partners; 0.9% homosexual relations), or for sex without penetration (20.5% oral sex; 1.1% anal coitus; 0.8% coitus without orgasm; 0.4% coitus interruptus). Some definitions or examples differ by gender. The amount of wrongs or incomplete answers put researchers on the alert about insufficient preventive knowledge in a population with a high educational level

During the last part of the 1990s the chance of surviving breast cancer increased. Changes in survival functions reflect a mixture of effects. Both, the introduction of adjuvant treatments and early screening with mammography played a role in the decline in mortality. Evaluating the contribution of these interventions using mathematical models requires survival functions before and after their introduction. Furthermore, required survival functions may be different by age groups and are related to disease stage at diagnosis. Sometimes detailed information is not available, as was the case for the region of Catalonia (Spain). Then one may derive the functions using information from other geographical areas. This work presents the methodology used to estimate age- and stage-specific Catalan breast cancer survival functions from scarce Catalan survival data by adapting the age- and stage-specific US functions. Methods: Cubic splines were used to smooth data and obtain continuous hazard rate functions. After, we fitted a Poisson model to derive hazard ratios. The model included time as a covariate. Then the hazard ratios were applied to US survival functions detailed by age and stage to obtain Catalan estimations. Results: We started estimating the hazard ratios for Catalonia versus the USA before and after the introduction of screening. The hazard ratios were then multiplied by the age- and stage-specific breast cancer hazard rates from the USA to obtain the Catalan hazard rates. We also compared breast cancer survival in Catalonia and the USA in two time periods, before cancer control interventions (USA 1975–79, Catalonia 1980–89) and after (USA and Catalonia 1990–2001). Survival in Catalonia in the 1980–89 period was worse than in the USA during 1975–79, but the differences disappeared in 1990–2001. Conclusion: Our results suggest that access to better treatments and quality of care contributed to large improvements in survival in Catalonia. On the other hand, we obtained detailed breast cancer survival functions that will be used for modeling the effect of screening and adjuvant treatments in Catalonia

En aquesta tesi s'han dut a terme dos tipus d'estudis diferents. L'objectiu del primer era la preservació del semen de porcí a 15ºC i el del segon eren els co-cultius homòlegs de cèl·lules epitelials de l'oviducte i espermatozoides de porcí. Pel que fa al primer estudi, s'ha observat que l'addició de la prostaglandina F2α i àcid hialurònic a les dosis seminals no malmena la qualitat espermàtica i que la tolerància dels espermatozoides als canvis d'osmolalitat del medi es pot correlacionar proves de fertilitat i prolificitat.. Respecte el segon, s'ha determinat que les cèl·lules oviductals afecten els paràmetres espermàtics i que la presència d'espermatozoides sobreexpressa els gens que codifiquen per les proteïnes de xoc tèrmic. Així, se suggereix que aquestes proteïnes tenen algun paper en els processos reproductius que tenen lloc a l'oviducte, malgrat que s'hagi observat, mitjançant la tècnica de la interferència de l'RNA, que la HSP90AA1 no està implicada en el perllongament de la viabilitat espermàtica.

A presente dissertação teve como objetivo compreender como se promove a Gestão da Divisão de Vigilância Sanitária pela Secretaria de Estado de Saúde Pública/SESPA no combate do HIV/AIDS no Estado do Pará. A pesquisa contemplou o processo de Gestão de Políticas Públicas em Saúde da Divisão de Vigilância em Saúde da Secretaria de Estado de Saúde Pública – SESPA no combate do HIV/AIDS no Estado do Pará, destacando os resultados dessa gestão nos casos notificados. Tratou-se de um estudo descritivo, cujos dados foram coletados a partir de levantamento bibliográfico e documental com aplicação de questionário na Divisão de Vigilância em Saúde da Secretaria do Estado de Saúde Pública/SESPA. O referencial teórico enfocou aspectos da contextualização da Gestão Pública e Privada, assim como fez referencia a Gestão de Políticas Públicas em Saúde em Portugal e no Brasil. Os resultados mostraram que a Gestão da Divisão de Vigilância Sanitária /SESPA consiste em uma Gestão Pública que realiza suas atividades sobre uma estrutura burocrata e centralizada impedindo que a mesma supra adequadamente, enquanto organização, às demandas do Estado do Pará e aos desafios impostos pelo HIV/AIDS, que se reafirma como assunto de saúde pública. Como conclusão, o estudo evidenciou que Gestão da Divisão da Vigilância em Saúde da Secretaria de Estado de Saúde Pública/SESPA no combate do HIV/AIDS não promoveu adequadamente suas ações, apresentando resultados satisfatórios, pois necessita de melhores políticas públicas que propiciem ações para o cumprimento de suas metas, fortalecendo a capacidade de organização e de articulação, como a redução efetiva das vulnerabilidades sociais e políticas que agenciam a expansão da epidemia, crescentemente associada às desigualdades sociais que vigoram no Estado do Pará.
