Glaucoma is a multifactorial condition under serious influence of many risk factors. The role of diabetes mellitus (DM) in glaucoma etiology or progression remains inconclusive. Although, the diabetic patients have different healing mechanism comparing to the general population and it has a possible-negative role on surgical outcomes. This review article attempts to analyze the association of both diseases, glaucoma and DM, before and after the surgery. The epidemiological studies, based mainly in population prevalence analyzes, have shown opposite outcomes in time and even in the most recent articles also the association remains inconclusive. On the contrary, the experimental models based on animal induced chronic hyperglycemia have shown an important association of both diseases, explained by common neurodegenerative mechanisms. Diabetic patients have a different wound healing process in the eye viz-a-viz other organs. The healing process is more and it results in lower surgical survival time, higher intraocular pressure (IOP) levels and, therefore, these patients usually need more medication to lower the IOP. Both randomized and nonrandomized retrospective and experimental molecular studies have shown the association between DM and glaucoma. Further studies are needed to get better explanations about outcomes on more recent surgical procedures and with the exponential use of antifibrotics.

Oral busulfan is the historical backbone of the busulfan+cyclophosphamide regimen for autologous stem cell transplantation. However intravenous busulfan has more predictable pharmacokinetics and less toxicity than oral busulfan; we, therefore, retrospectively analyzed data from 952 patients with acute myeloid leukemia who received intravenous busulfan for autologous stem cell transplantation. Most patients were male (n=531, 56%), and the median age at transplantation was 50.5 years. Two-year overall survival, leukemia-free survival, and relapse incidence were 67±2%, 53±2%, and 40±2%, respectively. The non-relapse mortality rate at 2 years was 7±1%. Five patients died from veno-occlusive disease. Overall leukemia-free survival and relapse incidence at 2 years did not differ significantly between the 815 patients transplanted in first complete remission (52±2% and 40±2%, respectively) and the 137 patients transplanted in second complete remission (58±5% and 35±5%, respectively). Cytogenetic risk classification and age were significant prognostic factors: the 2-year leukemia-free survival was 63±4% in patients with good risk cytogenetics, 52±3% in those with intermediate risk cytogenetics, and 37 ± 10% in those with poor risk cytogenetics (P=0.01); patients ≤50 years old had better overall survival (77±2% versus 56±3%; P<0.001), leukemia-free survival (61±3% versus 45±3%; P<0.001), relapse incidence (35±2% versus 45±3%; P<0.005), and non-relapse mortality (4±1% versus 10±2%; P<0.001) than older patients. The combination of intravenous busulfan and high-dose melphalan was associated with the best overall survival (75±4%). Our results suggest that the use of intravenous busulfan simplifies the autograft procedure and confirm the usefulness of autologous stem cell transplantation in acute myeloid leukemia. As in allogeneic transplantation, veno-occlusive disease is an uncommon complication after an autograft using intravenous busulfan.

Serious infections are a major cause of morbidity and mortality in systemic inflammatory rheumatic disease (SIRD) patients. Although vaccination may prevent numerous infections, vaccination uptake rates are low in this group of patients. OBJECTIVES: To develop evidence-based recommendations for vaccination in SIRD patients. METHODS: We searched MEDLINE (until 31 October 2014) and EMBASE (until 14 December 2014) databases, as well as the ACR and EULAR congress abstracts (2011-2014). Patients with any systemic inflammatory rheumatic disease were included and all vaccines were considered. Any safety and efficacy outcomes were admitted. Search results were submitted to title and abstract selection, followed by detailed review of suitable studies. Data were subsequently pooled according to the type of vaccine and the SIRD considered. Results were presented and discussed by a multidisciplinary panel and systematic literature review (SLR)-derived recommendations were voted according to the Delphi method. The level of agreement among rheumatologists was assessed using an online survey. RESULTS: Eight general and seven vaccine-specific recommendations were formulated. Briefly, immunization status should routinely be assessed in all SIRD patients. The National Vaccination Program should be followed and some additional vaccines are recommended. To maximize the efficacy of vaccination, vaccines should preferably be administered 4 weeks before starting immunosuppression or, if possible when disease activity is controlled. Non-live vaccines are safe in SIRD, including immunosuppressed patients. The safety of live attenuated vaccines in immunosuppressed patients deserves further ascertainment, but might be considered in particular situations. DISCUSSION: The present recommendations combine scientific evidence with the multidisciplinary expertise of our taskforce panel and attained desirable agreement among Portuguese rheumatologists. Vaccination recommendations need to be updated on a regular basis, as more scientific data regarding vaccination efficacy and safety, emergent infectious threats, new vaccines as well as new immunomodulatory therapies become available.

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.

RESUMO - Enquadramento: As mudanças demográficas e na estrutura social das famílias precipitaram reformas das políticas dos cuidados de longa duração da população idosa no continente Europeu. Após um período em que as mulheres assumiam o papel de principais cuidadoras dos membros mais idosos, o aumento da sua inclusão no mercado de trabalho, assim como o envelhecimento geral da população introduziu mudanças no enquadramento dos cuidados a idosos. Estas mudanças têm particular impacte nos países da Europa do Sul, visto que tradicionalmente o cuidado a idosos é prestado maioritariamente pelo sector informal. Finalidade/objectivos: O presente estudo tem como finalidade conhecer as características dos cuidadores informais e dos idosos dependentes em Portugal. Definiram-se três objectivos principais. O primeiro é compreender a realidade demográfica, de saúde e dependência funcional dos idosos alvo de cuidados informais em Portugal. Em segundo pretende-se conhecer a situação actual dos prestadores informais de cuidados de longa duração em Portugal. Em terceiro, discutem-se os aspectos que mais influenciam a acessibilidade a cuidados informais entre os idosos dependentes em Portugal. Metodologia: Para concretizar estes objectivos, para além de se proceder a uma sistematização bibliográfica da literatura mais relevante nesta área, recorre-se à análise descritiva e regressão logística binária. Utilizando os dados do inquérito Survey of Health, Ageing and Retirement in Europe descreve-se a realidade nacional dos idosos dependentes e seus cuidadores informais e estimam-se modelos de acessibilidade aos cuidados informais em Portugal. Resultados/conclusões: Este estudo contribui para o conhecimento de três aspectos fundamentais sobre os cuidados informais em Portugal: o primeiro prende-se com a quantificação da realidade nacional dos idosos dependentes em Portugal; o segundo relaciona-se com a quantificação da situação portuguesa dos cuidadores informais; e, por último, estima-se modelos explicativos sobre a acessibilidade a cuidados informais. Para além da quantificação da realidade nacional, o principal contributo deste trabalho reside na demonstração de que o actual modelo de prestação de cuidados (baseado nos cuidados informais prestados por membros da família) deixa de fora uma parte significativa dos idosos dependentes. Na verdade, este estudo demonstra que uma parte significativa dos idosos não tem acesso a cuidados e que, embora sejam os elementos da família que maioritariamente prestam os cuidados informais, esse facto, por si só, não explica o acesso aos cuidados.

RESUMO - Durante todo o seu ciclo de vida, o medicamento está sujeito a padrões de qualidade, segurança e eficácia, alicerçados numa atuação conjunta dos responsáveis pela sua colocação no mercado, das autoridades competentes nacionais e comunitárias. Os diferentes intervenientes estão sujeitos a um conjunto de obrigações e procedimentos que englobam também a sua fase final de retirada do mercado, devolução, recolha e valorização ou reciclagem. Neste trabalho é caracterizada a cadeia de distribuição do medicamento assim como o seu fluxo físico no sentido inverso, ou seja, o processo de devolução e de tratamento ambientalmente adequado para os resíduos de medicamentos. A maioria da literatura a respeito das devoluções de medicamentos enfatiza a vertente ecológica do sistema de logística inversa. Neste trabalho, as questões ambientais são discutidas , mas o objectivo primário focaliza questões económicas relacionadas com o processo de devoluções. São apresentadas as possíveis vantagens teóricas da criação de um sistema centralizado de gestão de devoluções, por oposição ao atual sistema de circuitos dispersos. Com a aplicação de um inquérito a armazenistas com larga responsabilidade no processo de devoluções, pretendeu-se avaliar os custos inerentes ao atual modelo. Os resultados obtidos indicam que existe margem potencial para reduzir custos neste processo, para a grande maioria dos armazenistas. Na área específica dos medicamentos fora de prazo de validade, o crescente desenvolvimento e aperfeiçoamento dos processos de devolução poderá direcionar-se no sentido da criação de centrais de devolução centralizadas.
