Estarão as (os/es) Profissionais da Psicologia Preparadas (os/es) para o Atendimento de Pessoas Trans?

Estarão as(os/es) psicólogas(os/es) preparados para o atendimento de pessoas trans? O presente estudo qualitativo objetivou averiguar se houve a transmissão de informações sobre a temática da transexualidade na formação acadêmica de psicólogas(os/es) brasileiros(as/es). Através de formulário online, foram obtidas cento e trinta e três respostas de psicólogas(os) voluntárias(os) das cinco regiões do país, que demonstram que pouco se aborda sobre a temática da transexualidade na formação em Psicologia, ainda que nos últimos anos tenha havido espaços para a transmissão e aquisição de conhecimentos sobre temáticas das sexualidades, gêneros e transexualidade nos cursos em Psicologia

LOW BACK PAIN IN ADOLESCENTS: A SCHOOL SCREENING

Introduction: Low back pain is a symptom with biopsychosocial implications with the potential to reach the whole individual. The school-age coincides with an important period in human development and in which inequalities and compensation resulting from poor posture or structural changes may increase the chance of the emergence of pain. Objective: To estimate the prevalence of low back pain among adolescents. Methods: The sample consisted of 166 adolescents between 11 and 18 years of age (86 girls and 80 boys) enrolled in a private school in a town in the state of Piauí, in the academic year 2012. A structured questionnaire with closed questions on gender and low back pain aspects was used. Results:Almost 80% of the students reported the presence of low back pain in the past year, and nearly half (41.3%) reported pain classified as 3,according tofaces pain scale.About two-thirds of the adolescents (63.1%) said they did not fail to perform their daily activities due to pain.There was no statistically significant association between gender and low back pain (p = 0.117) or pain intensity (p = 0.065), although for the latter a variable marginal p-value was found. Conclusion: A high prevalence of low back pain was found in the study group without gender differences regarding pain characteristics

Concentração de retinol em bebidas lácteas achocolatadas enriquecidas em comparação às quantidades declaradas no rótulo

A bebida láctea achocolatada é um produto lácteo amplamente consumido e que pode ser enriquecido com nutrientes essenciais, como forma de reforçar o seu valor nutricional e prevenir ou corrigir carências específicas na população, especialmente em crianças. Um desses nutrientes é a vitamina A, cuja deficiência é considerada um problema de saúde pública. O objetivo deste estudo foi quantificar o retinol presente em bebidas lácteas achocolatadas Ultra High Temperature - UHT enriquecidas e verificar a compatibilidade com os valores especificados nos rótulos. Para tanto, foram selecionadas aleatoriamente três marcas desses produtos (A, B e C), analisadas através de Cromatografia Líquida de Alta Eficiência (CLAE). A concentração de retinol é dada em μg/dL e os valores expressos em média e desvio-padrão. Os resultados mostraram que as marcas A e C apresentaram concentração de retinol condizente com a descrita nos rótulos (70,5 ±6,8 μg/dL e 73,5 ±8,2 μg/dL). Entretanto, a marca B apresentou concentração muito baixa (9,0 ±3,2 μg/dL), conflitante com a declarada (75,0 μg/dL). Tal situação evidencia a ausência de suplementação no achocolatado da marca B, fazendo-se necessária uma maior fiscalização nesses produtos, a fim de garantir que as informações presentes nos rótulos sejam confiáveis

Spectrophotometry of Winkler and White's official methods for the determination of hydroxymethylfurfural in bee honey

Abstract The determination of hydroxymethylfurfural (HMF) in bee honey is performed by the spectrophotometric methods Winkler's and White's. The Winkler method reads the absorbances in the visible region of the spectrum, and the White method measures in the ultraviolet (UV) and visible regions of the spectrum. This study aims to compare the spectrophotometric methodologies of White and Winkler to the determination of HMF in bee honey. For the study, it was used a UV-visible spectrophotometer, 10 mm optical path quartz cuvettes, and ten bee honey samples of different flowering. Absorbances at 550 nm were analyzed by the Winkler method; absorbances at 284 nm and 336 nm in the White method; and a comparison of HMF concentration (mg/kg) was carried out between the methods. The results showed significant differences (p<0.05) in HMF concentration determined by both methods. The main conclusion is that the Winkler method presents higher HMF values than the White method

High Zika Virus Seroprevalence in Salvador, Northeastern Brazil Limits the Potential for Further Outbreaks.

During 2015 to 2016, Brazil reported more Zika virus (ZIKV) cases than any other country, yet population exposure remains unknown. Serological studies of ZIKV are hampered by cross-reactive immune responses against heterologous viruses. We conducted serosurveys for ZIKV, dengue virus (DENV), and Chikungunya virus (CHIKV) in 633 individuals prospectively sampled during 2015 to 2016, including microcephaly and non-microcephaly pregnancies, HIV-infected patients, tuberculosis patients, and university staff in Salvador in northeastern Brazil using enzyme-linked immunosorbent assays (ELISAs) and plaque reduction neutralization tests. Sera sampled retrospectively during 2013 to 2015 from 277 HIV-infected patients were used to assess the spread of ZIKV over time. Individuals were georeferenced, and sociodemographic indicators were compared between ZIKV-positive and -negative areas and areas with and without microcephaly cases. Epidemiological key parameters were modeled in a Bayesian framework. ZIKV seroprevalence increased rapidly during 2015 to 2016, reaching 63.3% by 2016 (95% confidence interval [CI], 59.4 to 66.8%), comparable to the seroprevalence of DENV (75.7%; CI, 69.4 to 81.1%) and higher than that of CHIKV (7.4%; CI, 5.6 to 9.8%). Of 19 microcephaly pregnancies, 94.7% showed ZIKV IgG antibodies, compared to 69.3% of 257 non-microcephaly pregnancies (P = 0.017). Analyses of sociodemographic data revealed a higher ZIKV burden in low socioeconomic status (SES) areas. High seroprevalence, combined with case data dynamics allowed estimates of the basic reproduction number R0 of 2.1 (CI, 1.8 to 2.5) at the onset of the outbreak and an effective reproductive number Reff of <1 in subsequent years. Our data corroborate ZIKV-associated congenital disease and an association of low SES and ZIKV infection and suggest that population immunity caused cessation of the outbreak. Similar studies from other areas will be required to determine the fate of the American ZIKV outbreak.IMPORTANCE The ongoing American Zika virus (ZIKV) outbreak involves millions of cases and has a major impact on maternal and child health. Knowledge of infection rates is crucial to project future epidemic patterns and determine the absolute risk of microcephaly upon maternal ZIKV infection during pregnancy. For unknown reasons, the vast majority of ZIKV-associated microcephaly cases are concentrated in northeastern Brazil. We analyzed different subpopulations from Salvador, a Brazilian metropolis representing one of the most affected areas during the American ZIKV outbreak. We demonstrate rapid spread of ZIKV in Salvador, Brazil, and infection rates exceeding 60%. We provide evidence for the link between ZIKV and microcephaly, report that ZIKV predominantly affects geographic areas with low socioeconomic status, and show that population immunity likely caused cessation of the outbreak. Our results enable stakeholders to identify target populations for vaccination and for trials on vaccine efficacy and allow refocusing of research efforts and intervention strategies
