Work overload and associated factors in healthcare professionals during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic changed the work routine of professionals at the family healthcare center (Núcleo de Atenção à Saúde da Família - NASF-AB), providing new conditions and work overload. OBJECTIVE: The purpose of this study was to explore factors associated with work overload in NASF-AB professionals during the COVID-19 pandemic. METHODS: A cross-sectional study was carried out with NASF-AB workers in the city of Salvador, Bahia, Brazil, from May to August 2021. Working conditions and overload were assessed using the National Program for Improving Access and the Quality of Primary Care questionnaire (Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica - PMAQ) and the scale measuring burden of professionals in mental health services (Escala de Avaliação da Sobrecarga de Profissionais em Serviços de Saúde Mental - IMPACTO-BR), respectively. A multivariate linear regression model was used. A total of 68 health professionals participated in the study, including 19 physiotherapists, 13 occupational therapists, 10 social workers, 10 nutritionists, 9 psychologists and 7 physical education professionals. RESULTS: There was a significant association between overall overload and being female (p=<0.005), having spaces for reflection on the work process (p=0.027), and having difficulty moving around to conduct activities in the territory (p=0.002) for increasing the chance of work overload. CONCLUSIONS: Our findings encourage workers' health policies and closer ties and negotiation with local management, as well as the return of the institutional support figure for the effectiveness and resolution of actions in primary healthcare units.

Changing patterns of vitellin-related peptides during development of the cattle tick Boophilus microplus.

The major components of protein extracts from the cattle tick Boophilus microplus eggs and larvae of various ages were characterized by molecular sieving chromatography, ion exchange chromatography and SDS-PAGE. The fractions analysed showed a changing chromatographic pattern development. A serum raised against the components of a fraction showing characteristics of vitellin strongly reacted in Western blots with the major peptides of extracts from eggs, larvae, gut and ovary. Comparison of patterns obtained by electrophoresis in non-denaturing PAGE, stained with Coomassie blue or with benzidine/hydrogen peroxide, revealed that the major proteins of these extracts are haemoproteins, possibly in different aggregation states or heterogeneous in composition.
