Salivary flow, amylase, and total protein in hospitalized patients with HIV infection / AIDS complications

Background: Saliva is a complex secretion produced daily by the salivary glands. Saliva consists mainly of water, enzymes, ions and amino acids and performs several important functions in oral health. Objective: The aim of this study was to investigate the flow rate and concentrations of amylase and total proteins in the saliva of hospitalized patients due to AIDS complications. Methods: Ninety-three men and women (20-64 years of age) were divided into two groups (46 HIV-infected patients and 47 controls) and had salivary flow rate and levels of amylase enzyme and total proteins evaluated. Results: The mean salivary flow rate was lower in individuals with HIV when compared to controls (P < 0.05). No significant difference between amylase enzyme levels and total proteins were observed in the saliva of patients with HIV infection when compared to controls. Conclusion: Individuals with HIV / AIDS infection (in hospital treatment) suffer no interference in levels of amylase and total salivary proteins, but they have significantly reduced salivary flow

Educação em saúde em universidades como forma de prevenção de infecções sexualmente transmissíveis na juventude

A educação sexual nas escolas para jovens é extremamente importante, pois é nessa fase da vida que muitas vezes são estabelecidos hábitos e comportamentos que podem afetar a saúde em longo prazo. Algumas das principais temáticas que podem ser abordadas na educação em saúde incluem a prevenção de doenças sexualmente transmissíveis, que objetiva principalmente informar sobre as práticas sexuais seguras, métodos contraceptivos, prevenção do HIV/AIDS e outras doenças sexualmente transmissíveis. Diante disso, o referente trabalho objetiva descrever a importância da educação em saúde nas universidades para jovens como forma de prevenção de infecções sexualmente transmissíveis. Trata-se de uma revisão integrativa da literatura, com carácter de estudo descritivo e abordagem qualitativa, em que foi realizada buscas no sistema da Biblioteca Virtual em Saúde do Ministério da Saúde, usando os seguintes descritores: Educação em Saúde; Infecções Sexualmente Transmissíveis e Saúde do Adolescente. A amostra finas foi composta por 9 artigos que melhor abordaram a temática. Mediante as análises realizadas, verificou-se que a prevenção de infecções sexuais é importante porque essas doenças podem ter graves consequências para a saúde, especialmente para os adolescentes. Ademais, é importante que a escola, os professores e os profissionais de saúde trabalhem em conjunto para ajudar a garantir que os alunos tenham acesso à informação correta e aos recursos necessários para cuidar da sua saúde sexual. É fundamental que a educação entre pares seja estimulada e valorizada como uma ferramenta importante na formação dos jovens, contribuindo para a construção de uma sociedade mais justa e equilibrada livre de infecções sexuais evitáveis

Association between breakfast frequency and physical activity and sedentary time : a cross-sectional study in children from 12 countries

BackgroundExisting research has documented inconsistent findings for the associations among breakfast frequency, physical activity (PA), and sedentary time in children. The primary aim of this study was to examine the associations among breakfast frequency and objectively-measured PA and sedentary time in a sample of children from 12 countries representing a wide range of human development, economic development and inequality. The secondary aim was to examine interactions of these associations between study sites.MethodsThis multinational, cross-sectional study included 6228 children aged 9-11years from the 12 International Study of Childhood Obesity, Lifestyle and the Environment sites. Multilevel statistical models were used to examine associations between self-reported habitual breakfast frequency defined using three categories (breakfast consumed 0 to 2days/week [rare], 3 to 5days/week [occasional] or 6 to 7days/week [frequent]) or two categories (breakfast consumed less than daily or daily) and accelerometry-derived PA and sedentary time during the morning (wake time to 1200h) and afternoon (1200h to bed time) with study site included as an interaction term. Model covariates included age, sex, highest parental education, body mass index z-score, and accelerometer waking wear time.ResultsParticipants averaged 60 (s.d. 25) min/day in moderate-to-vigorous PA (MVPA), 315 (s.d. 53) min/day in light PA and 513 (s.d. 69) min/day sedentary. Controlling for covariates, breakfast frequency was not significantly associated with total daily or afternoon PA and sedentary time. For the morning, frequent breakfast consumption was associated witha higher proportion of time in MVPA (0.3%), higher proportion of time in light PA (1.0%) and lower min/day and proportion of time sedentary (3.4min/day and 1.3%) than rare breakfast consumption (all p0.05). No significant associations were found when comparing occasional with rare or frequent breakfast consumption, or daily with less than daily breakfast consumption. Very few significant interactions with study site were found.ConclusionsIn this multinational sample of children, frequent breakfast consumption was associated with higher MVPA and light PA time and lower sedentary time in the morning when compared with rare breakfast consumption, although the small magnitude of the associations may lack clinical relevance.Trial registrationThe International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) is registered at(Identifier NCT01722500).Peer reviewe
