    The aims of this study were to summarize and describe the influences of phytoplankton on the larval cycle of rocky shore invertebrates, and to assess the relationship between fluctuations in chlorophyll-a concentration and the rates of larval processes. We carried out a mini review of the published data regarding the theme of the chapter, in which we described the ecological trends for the most common taxa and key species at small and larger spatiotemporal scales. The following topics were addressed: (i) the influence of phytoplankton on larval development, rhythms of larval release, larval quality, larval transport, settlement, and recruitment; (ii) the relationships between variations in chlorophyll-a concentration and the rates of larval processes; (iii) climate change on phytoplankton larva dynamics. The information presented here highlights the role of phytoplankton on rocky shore communities, as well as the importance of chlorophyll-a as a tool for modeling and forecasting the supply side ecology in rocky shore communities

    Objective: To estimate the prevalence of spine postural deviations in Brazilian schoolchildren. Methods: Searches were conducted in databases EMBASE, LILACS, PubMed, SCOPUS, SciELO, Science Direct, and Web of Science, as well as manual searches to identify studies that evaluated the prevalence of spine postural deviations in Brazilian schoolchildren. Two independent reviewers realized the study selection, evaluated the methodological quality and the risk of bias and extracted data. The homogeneity between the studies was evaluated and the quality of evidence level using the GRADE system. Results: 29 studies were included, of which extracted the frequency of positive events to changes in cervical, thoracic and lumbar spine, as well as the frequency of scoliosis between schoolchildren. Even performing the meta-analysis separated by subgroups according to the spine region, the heterogeneity level it was up to 90%, it is not possible to perform the meta-analysis to estimate the prevalence of spine postural deviations in Brazilian schoolchildren. Conclusion: There is low strength of evidence to establish a consensus about the values of the prevalence of spine postural deviations in Brazilian schoolchildren

    O estudo teve objetivo de desenvolver um questionário sobre hábitos relacionados ao trabalho (QHT) e verificar sua validade e reprodutibilidade. As etapas do QHT foram: observação de campo e revisão teórica sobre hábitos relacionados ao trabalho de profissionais da área da saúde; descrição e conteúdo; validade de conteúdo e reprodutibilidade. Para análise dos dados foi utilizado estatística descritiva (validade de conteúdo) e percentual de concordância(%C) e a medida de concordância Kappa (reprodutibilidade). Seis especialistas avaliaram a maior parte do instrumento como excelente, considerando-o válido em seu conteúdo. Os valores de Kappa mostraram concordância moderadas a excelentes entre as respostas(%C>80%), indicando ser o QHT um instrumento reprodutível. Apesar das limitações do QHT tais como ausência de questões sobre etilismo e desequilíbrio entre demanda de trabalho e disponibilidade de recursos humanos, o alcance prático do instrumento está na suafacilidade em obtenção de informações para conhecer o perfil e alguns importantes aspectos de rotina de trabalho dos trabalhadores da saúde, útil para avaliação na área da Terapia Ocupacional.The aim of this study was to develop a questionnaire about work-related habits (WHQ) and to verify its validity and reproducibility. The WHQ steps were: field observation and theoretical review about work-related habits of health workers; description and content; content validity,and reproducibility. Descriptive statistics (content validity), percent agreement (%C), and the measure agreement Kappa (reproducibility) were used for data analysis. Six experts assessed most part of the instrument as excellent, considering its content valid. Kappa values showed moderate to excellent concordance among the answers (%C>80%) indicating the reproducibility of the WHQ. Despite the limitations of the WHQ, such as absence of questions about alcoholism and imbalance between labor demand and availability of human resources, the practical range of the instrument is in the facility in obtaining information on the profile and on some important aspects of the work routine of health workers, which is useful to evaluate the Occupational Therapy field

    AbstractBackground: The preventive and compulsory social isolation regulations due to COVID-19 affected the entire population, but this became more emphasized in the group of older adults. Many older adults who attended workshops, retirement centers and clubs had to interrupt their activities. This has impacted negatively on their activity level, socialization, and emotional state. The aim of the present study is to present preliminary results of the implementation of an online activities and psychoeducational program to prevent cognitive decline and promote healthy aging habits on older adults who live in Argentina in the context of Covid-19 Pandemic.Method. Design: Descriptive study. Subjects: 396 self-validated older adults, male and female. Instruments: socio-demographic and social participation questionnaire. Procedure: The intervention consists of a series of workshops (yoga, meditation, gym, singing lessons, memory, preparation for retirement and reflection about grief) and monthly specialist ´s talks on different topics about healthy aging. All the activities where done through zoom platform. All participants where offer one to one capacitation and written material about how to use this platform. Older adults could choose in how many activities they would take part in.Results. Data of 396 older adults who have taken part in the on-line version of the program on 2020 indicate that median age was 70.66 years old (ds= 8,7) of which 86 % were women. 79 % took part in specialists talks and 68 % on workshops and talks.Discussion: These results provide empirical evidence regarding the need to implement online intervention programs for older adults. Participating in an online educational program could increase participant?s cognitive healthy habits literacy, empowerment and engagement in brain health promotion activities, which in turn could reduce their dementia risk and feeling of loneliness in pandemic context.Fil: Feldberg, Carolina.

    Objetivo: identificar a prevalência de dor musculoesquelética, distúrbios osteomusculares relacionadas ao trabalho (Dort), doenças cardiovasculares (DCV) e fatores associados em profissionais do SAMU 192 em Porto Alegre/RS. Métodos: 113 trabalhadores (37% da equipe do SAMU de Porto Alegre) responderam a um questionário de hábitos relacionados ao trabalho, riscos ocupacionais e aparecimento de DCV e Dort. A análise estatística foi realizada com tabelas de frequência, teste qui-quadrado e razões de prevalência – intervalo de confiança de 95% (IC 95%) – por meio de análise multivariável (modelo de regressão de Poisson), com α=0,05. Resultados: Todos os participantes estavam na condição de sobrepeso e apresentavam alta prevalência de dor (92,9%) e Dort (50,4%) e baixa prevalência de DCV (8,8%). A idade contribuiu para o aumento no risco de aparecimento da dor. Os fatores associados ao aparecimento da Dort foram exposição a frio, calor e vibrações, esforço físico, ausência de pausa nas atividades, profissão, regime de trabalho e estresse. A ligação entre os fatores associados e DCV não foi possível devido à baixa prevalência de DCV entre os trabalhadores. Conclusão: os profissionais do SAMU apresentaram alta prevalência de dor e Dort e baixa prevalência de DCV.Objective: To determine the prevalence of musculoskeletal pain, Cumulative Trauma Disorders (CTD) and cardiovascular disease (CVD) and identify the associated factors in the emergency professionals of Porto Alegre/RS. Methods: 113 workers (37% of SAMU 192 Porto Alegre/RS) answered a questionnaire about work-related habits, occupational risks and the onset of CTD and CVD. Statistical analysis was performed using frequency tables, chi-square test and prevalence ratios (95%) through multivariate analysis (Poisson’s regression model). Considering α=0.05. Results: All participants were in the overweight condition and showed high prevalence of pain (92.9%) and CTD (50.4%), and low CVD prevalence (8.8%). Age acted as a risk for pain. Factors associated with CTD were exposure to cold and heat, exposure to vibrations, physical exertion, no breaks in between activities, occupation, working hours and stress. The association between risk and CVD was not possible due to the low prevalence of CVD among workers. Conclusion: SAMU 192 professionals of Porto Alegre/RS showed high prevalence of pain and CTD, and low prevalence of CVD
