Iguais ou diferentes? Cuidados de saúde materno-infantil a uma população de imigrantes

Os concelhos de Amadora e Sintra constituem um território de fortes características de identidade na Área Metropolitana de Lisboa que resultam, entre outros aspectos, da elevada densidade populacional (sobretudo Amadora), do marcado crescimento na última década (sobr etudo Sintra, onde a população residente aumentou cerca de 40% entre 1991 e 2001) e, principalmente, da sua diversidade social, cultural e étnica. D e facto, a proporção de imigrantes nestes concelhos atinge um dos v alores mais elevados do país. A equidade na pr estação de cuidados tem sido demonstrada como factor de r edução das disparidades na saúde que determina a morbilidade e a mortalidade decorrentes da assimetria das populações. Na Unidade de Saúde D (Hospital Fernando Fonseca e 9 Centr os de Saúde da Amadora e Sintra), não tinha ainda sido desenvolvida uma investigação científica estruturada sobre os níveis de saúde e o acesso e utilização dos serviços e que sustentem políticas ajustadas às vulnerabilidades deste grupo. Este conhecimento possibilita a reorganização dos serviços de cuidados de saúde e é fundamental para (r e)pensar processos de planeamento e modelos de inter venção que culminem numa integração de sucesso para o século XXI.info:eu-repo/semantics/publishedVersio

Diagnostic value of CSF protein profile in a Portuguese population of sCJD patients

The clinical diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) is difficult, and reliable markers are highly desired. In this work we assess the value of several cerebrospinal fluid (CSF) markers for sCJD diagnosis. Within the framework of the Portuguese Epidemiological Surveillance Program for Human Prion Diseases, CSF samples from 71 patients with clinically suspected sCJD, 30 definite sCJD and 41 non-CJD patients, were analysed for the presence of 14-3-3 protein. CSF levels of tau (t-tau), and phosphorylated tau (p-tau181), S-100b and beta amyloid (Abeta42) proteins were determined. The influence of clinical and genetic characteristics on CSF markers sensitivity was also evaluated. Protein 14-3-3 was detected in 29/30 sCJD patients and 9/41 non-CJD patients. Extremely elevated t-tau and S-100b protein levels were found in sCJD patients, while p-tau181 levels were only slightly elevated and Abeta42 showed no differences compared to controls. 14-3-3 was the most sensitive parameter (97%), but its specificity was low (78%); sensitivity/specificity for other proteins were: S-100b-93/93%, t-tau-93/95%, with maximum accuracy being obtained by a combination of tests (14-3-3 combined with either t-tau or S-100b, or combining S-100b with t-tau/Abeta42 or p-tau/t-tau ratios). The sensitivity of 14-3-3, as well as of p-tau181/t-tau ratio, was decreased in younger patients with long disease duration, with the PrP-2 isotype and MV genotype. Both 14-3-3, t-tau and S-100b are sensitive markers for sCJD, but 14-3-3 specificity seems to be lower in this special clinical setting of rapidly progressing dementias. We propose that in cases with a 14-3-3 weak positive result, or in young patients with long disease duration, a second CSF marker would be valuable for the diagnosis of sCJD

Fighting Misconceptions to Improve Compliance with Influenza Vaccination among Health Care Workers: An Educational Project

The compliance with influenza vaccination is poor among health care workers (HCWs) due to misconceptions about safety and effectiveness of influenza vaccine. We proposed an educational prospective study to demonstrate to HCWs that influenza vaccine is safe and that other respiratory viruses (RV) are the cause of respiratory symptoms in the months following influenza vaccination. 398 HCWs were surveyed for adverse events (AE) occurring within 48 h of vaccination. AE were reported by 30% of the HCWs. No severe AE was observed. A subset of 337 HCWs was followed up during four months, twice a week, for the detection of respiratory symptoms. RV was diagnosed by direct immunofluorescent assay (DFA) and real time PCR in symptomatic HCWs. Influenza A was detected in five episodes of respiratory symptoms (5.3%) and other RV in 26 (27.9%) episodes. The incidence density of influenza and other RV was 4.3 and 10.8 episodes per 100 HCW-month, respectively. The educational nature of the present study may persuade HCWs to develop a more positive attitude to influenza vaccination

The value of subtraction MRI in detection of amyloid-related imaging abnormalities with oedema or effusion in Alzheimer's patients: An interobserver study

BACKGROUND: Immunotherapeutic treatments targeting amyloid-β plaques in Alzheimer's disease (AD) are associated with the presence of amyloid-related imaging abnormalities with oedema or effusion (ARIA-E), whose detection and classification is crucial to evaluate subjects enrolled in clinical trials. PURPOSE: To investigate the applicability of subtraction MRI in the ARIA-E detection using an established ARIA-E-rating scale. METHODS: We included 75 AD patients receiving bapineuzumab treatment, including 29 ARIA-E cases. Five neuroradiologists rated their brain MRI-scans with and without subtraction images. The accuracy of evaluating the presence of ARIA-E, intraclass correlation coefficient (ICC) and specific agreement was calculated. RESULTS: Subtraction resulted in higher sensitivity (0.966) and lower specificity (0.970) than native images (0.959, 0.991, respectively). Individual rater detection was excellent. ICC scores ranged from excellent to good, except for gyral swelling (moderate). Excellent negative and good positive specific agreement among all ARIA-E imaging features was reported in both groups. Combining sulcal hyperintensity and gyral swelling significantly increased positive agreement for subtraction images. CONCLUSION: Subtraction MRI has potential as a visual aid increasing the sensitivity of ARIA-E assessment. However, in order to improve its usefulness isotropic acquisition and enhanced training are required. The ARIA-E rating scale may benefit from combining sulcal hyperintensity and swelling. KEY POINTS: • Subtraction technique can improve detection amyloid-related imaging-abnormalities with edema/effusion in Alzheimer's patients. • The value of ARIA-E detection, classification and monitoring using subtraction was assessed. • Validation of an established ARIA-E rating scale, recommendations for improvement are reported. • Complementary statistical methods were employed to measure accuracy, inter-rater-reliability and specific agreement

Renormalization group equation and scaling solutions for f(R) gravity in exponential parametrization

We employ the exponential parametrization of the metric and a \u201cphysical\u201d gauge fixing procedure to write a functional flow equation for the gravitational effective average action in an f(R) truncation. The background metric is a four-sphere and the coarse-graining procedure contains three free parameters. We look for scaling solutions, i.e. non-Gaussian fixed points for the function f. For a discrete set of values of the parameters, we find simple global solutions of quadratic polynomial form. For other values, global solutions can be found numerically. Such solutions can be extended in certain regions of parameter space and have two relevant directions. We discuss the merits and the shortcomings of this procedure. \ua9 2016, The Author(s)
