    Rationale: The issue of stigmatization is one of the most common psychosocial problems faced by people with epilepsy. Purpose: A second step towards the development of a scale to measure epilepsy stigma. Method: We applied a closed questionnaire to 12 patients and 32 relatives from the Epilepsy Outpatient Clinic at the University Hospital of Campinas. Results: The results are grouped in three main domains: medical, social and personal areas. Medical: the subjects did not know exactly what epilepsy is or how it is caused; nonetheless they know how to treat it. Social: the most important areas that people with epilepsy are discriminated are at work and social relationships. Patients also complained about their lack of freedom and limits on recreation activities. Personal Area: subjects apparently have the same feelings and thoughts about epilepsy and seizures. Conclusion: This study analyzed the most common aspects presented in the questionnaire to assess epilepsy stigma for the Brazilian culture which are the base to the elaboration of a stigma scale of epilepsy.632B39539

    A phytochemical study of Fridericia formosa (Bignoniaceae) ethanol extracts of leaves, stems, and fruits was guided by in vitro assays against vaccinia virus Western Reserve (VACV-WR), human herpes virus 1 (HSV-1), murine encephalomyocarditis virus (EMCV), and dengue virus type 2 (DENV-2) by the MTT method. All the ethanol extracts were active against DENV-2, HSV-1, and VACV-WRwith best results for the fruits extract against DENV-2 (SI > 38.2). For VACV-WRand HSV-1, EC50 values > 200 ?g mL?1 were determined, while no inhibition of the cytopathic effect was observed with EMCV. Five compounds were isolated and identified as the C-glucosylxanthones mangiferin (1), 2?-O-trans-caffeoylmangiferin (2), 2?-O-trans-coumaroylmangiferin (3), 2?- O-trans-cinnamoylmangiferin (5), and the flavonoid chrysin (4). The most active compound was 2?-O-trans-coumaroylmangiferin (3) with SI > 121.9 against DENV-2 and 108.7 for HSV-1. These results indicate that mangiferin cinnamoyl esters might be potential antiviral drugs

    Posterior cortical atrophy (PCA) is an understudied visual impairment syndrome most often due to “posterior Alzheimer's disease (AD)” pathology. Case studies detected mutations in PSEN1, PSEN2, GRN, MAPT, and PRNP in subjects with clinical PCA. To detect the frequency and spectrum of mutations in known dementia genes in PCA, we screened 124 European-American subjects with clinical PCA (n = 67) or posterior AD neuropathology (n = 57) for variants in genes implicated in AD, frontotemporal dementia, and prion disease using NeuroX, a customized exome array. Frequencies in PCA of the variants annotated as pathogenic or potentially pathogenic were compared against ∼4300 European-American population controls from the NHLBI Exome Sequencing Project. We identified 2 rare variants not previously reported in PCA, TREM2 Arg47His, and PSEN2 Ser130Leu. No other pathogenic or potentially pathogenic variants were detected in the screened dementia genes. In this first systematic variant screen of a PCA cohort, we report 2 rare mutations in TREM2 and PSEN2, validate our previously reported APOE ε4 association, and demonstrate the utility of NeuroX

    <p>Abstract</p> <p>Background</p> <p>In spite of the fact that pharmaceutical services are an essential component of all malaria programmes, quality of these services has been little explored in the literature. This study presents the first results of the application of an evaluation model of pharmaceutical services in high-risk municipalities of the Amazon region, focusing on indicators regarding organization of services and prescribing according to national guidelines.</p> <p>Methods</p> <p>A theoretical framework of pharmaceutical services for non-complicated malaria was built based on the Rapid Evaluation Method (WHO). The framework included organization of services and prescribing, among other activities. The study was carried out in 15 primary health facilities in six high-risk municipalities of the Brazilian Amazon. Malaria individuals ≥ 15 years old were approached and data was collected using specific instruments. Data was checked by independent reviewers and fed to a data bank through double-entry. Descriptive variables were analyzed.</p> <p>Results</p> <p>A copy of the official treatment guideline was found in 80% of the facilities; 67% presented an environment for receiving and prescribing patients. Re-supply of stocks followed a different timeline; no facilities adhered to forecasting methods for stock management. No shortages or expired anti-malarials were observed, but overstock was a common finding. On 86.7% of facilities, the average of good storage practices was 48%. Time between diagnosis and treatment was zero days. Of 601 patients interviewed, 453 were diagnosed for <it>Plasmodium vivax</it>; of these, 99.3% received indications for the first-line scheme. Different therapeutic schemes were given to <it>Plasmodium falciparum </it>patients. Twenty-eight (4.6%) out of 601 were prescribed regimens not listed in the national guideline. Only 5.7% individuals received a prescription or a written instruction of any kind.</p> <p>Conclusions</p> <p>The results show that while diagnostic procedure is well established and functioning in the Brazilian malaria programme, prescribing is still an activity that is actually not performed. The absence of physicians and poor integration between malaria services and primary health services make for the lack of a prescription or written instruction for malaria patients throughout the Brazilian Amazon. This fact may lead to a great number of problems in rational use and in adherence to medication.</p

    Lupeol, a triterpene frequently found in Asteraceae plant species, showed moderate to low activity in different strains of Plasmodium falciparum, the most virulent malaria etiological agents. In this work, lupeol was isolated from Parahancornia fasciculata, a plant that is used to treat malaria in the Amazonia region. In the search of more activity lupeol derivatives, five new 1,2,3-triazole hybrid molecules were synthetized by copper-catalyzed azide-alkyne cycloaddition. The antiplasmodial activity of the semi-synthetic compounds were evaluated by the lactate dehydrogenase assay; the lupeol propargyl ether was the only one to disclosing increased activity (half maximal inhibitory concentration-IC50-62.0 ? 1.92 ?mol L-1) in relation to lupeol (IC50 117.00 ?mol L-1). Therefore, this work revealed a new class of interesting lupeol derivatives that can be obtained by linking electron donors to the hydroxy group at C-3

    OBJETIVO Analisar a cobertura de testagem para sífilis durante a assistência pré-natal e estimar a prevalência de sífilis na gestação. MÉTODOS Coorte nacional de base hospitalar, realizada no Brasil, de 2011 a 2012, com 23.894 mulheres. Foram utilizados dados obtidos na entrevista com a puérpera, no prontuário hospitalar e nos cartões de pré-natal. Foram considerados casos de sífilis na gestação todas as gestantes com resultado de sorologia reagente no cartão ou diagnóstico de sífilis durante a internação para o parto. Prevalência de sífilis e coberturas de testagem foram analisadas segundo região de residência, cor da pele, escolaridade, idade materna e tipo de serviço de assistência pré-natal e ao parto, com utilização do teste estatístico Qui-quadrado. RESULTADOS Houve cobertura pré-natal de 98,7% das mulheres, cobertura de testagem para sífilis de 89,1% (um exame) e 41,2% (dois exames), bem como prevalência de sífilis na gestação de 1,02% (IC95% 0,84;1,25). Menor cobertura pré-natal foi observada na região Norte, em indígenas, em mulheres com menor escolaridade e naquelas atendidas em serviços públicos. Coberturas mais baixas de testagem ocorreram em residentes nas regiões Norte, Nordeste e Centro-Oeste, Sul em mulheres não brancas, mais jovens, de menor escolaridade e atendidas em serviços públicos. Maior prevalência de sífilis foi estimada em mulheres com menos de oito anos de escolaridade (1,74%), que se declararam pretas (1,8%) ou pardas (1,2%), mulheres sem pré-natal (2,5%) e naquelas atendidas em serviços públicos (1,37%) ou mistos (0,93%). CONCLUSÕES A prevalência estimada de sífilis na gestação foi semelhante à encontrada no último Estudo-Sentinela Parturiente realizado em 2006. Houve ampliação da cobertura pré-natal e de testagem, com alcance das metas sugeridas pela Organização Mundial da Saúde em duas regiões. Desigualdades regionais e sociais no acesso aos serviços de saúde, aliadas a outras falhas na assistência, para a persistência da sífilis congênita como importante problema de saúde pública no País.OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test) and 41.2% (two tests), and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25). A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%), who self-reported as black (1.8%) or mixed (1.2%), those who did not receive prenatal care (2.5%), and those attending public (1.37%) or mixed (0.93%) health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions. Regional and social inequalities in access to health care units, coupled with other gaps in health assistance, have led to the persistence of congenital syphilis as a major public health problem in Brazil
