Níveis de carnitina na ração no desempenho corporal de tricogáster léri (Trichogaster leeri bleeker, 1852)

Foram avaliados os efeitos de carnitina na dieta de Trichogaster leeri, com peso inicial de 0,5±0,2g, distribuídos aleatoriamente e individualmente em aquários plásticos (1000mL), com renovação total da água a cada 48 horas. Cinco dietas isocalóricas, contendo 28% de proteína bruta e 3100kcal de energia bruta, foram elaboradas com a suplementação de T1 = 0mg, T2 = 300mg, T3 = 600mg, T4 = 900mg e T5 = 1200mg de l-carnitina/kg de ração. As dietas foram administradas três vezes ao dia, ad libitum, durante 45 dias. Foram avaliados comprimento total e padrão, altura, peso final e tamanho de cauda, além do ganho de peso, conversão alimentar e fator de condição. Em todas as características analisadas, o tratamento de 900mg de carnitina/kg foi o mais eficiente no desempenho zootécnico para o T. leeri, e, após cálculos dos pontos máximos, sugere-se a concentração de 1.000mg/kg de ração. Observou-se diferença significativa para tamanho de cauda, altura do corpo, peso final e fator de condição

Presenteeism in nurses: comparative study of Spanish, Portuguese and Brazilian nurses

Aim:To compare presenteeism levels among three samples of nurses and to identify the relationship between presenteeism andsociodemographic and professional characteristics.Background:Presenteeism (going to work ill) is a phenomenon studied from different perspectives, and it has become especially important duringthe current COVID-19 outbreak; its connection to high healthcare costs, patient safety breaches and negative nurse well-being has been proved.Introduction:The nursing profession is particularly associated with caring for the culture of teamwork, loyalty to colleagues and professionalidentity. This condition enhances the ‘super nurse phenomenon’, even though nurses do not feel physically and psychologically able to work.Methods:A multicentre, cross-sectional study was conducted in three different country contexts: Oviedo (Spain), Porto (Portugal) andS~ao Paulo (Brazil). Nurses performing functions in hospitals and primary health care were enrolled. Informed consent and datacollection questionnaires were hand delivered. The Stanford Presenteeism Scale-6 was applied.Results:A total of 659 nurses participated. Portuguese nurses showed greater prevalence of presenteeism, followed by Brazilian andSpanish nurses. Younger nurses with less professional experience presented lower levels of presenteeism but greater psychologicalcommitment. Male participants showed lower capacity to complete work when ill than female participants.Conclusions:Age and length of professional experience proved to be significant predictors of total presenteeism, although onlyprofessional experience revealed statistical significance in the adjusted model.Implications for Nursing and Health Policy:The knowledge of this phenomenon among nurses highlights the need for thedevelopment of strategies in the curriculum of nursing students and organizations. Resilience and ergonomic training should be appliedin the training programmes of the students and reinforced by the health centre managers. It is essential that healthcare systems design worksite wellness programmes that pursue greater physical and mental well-being for healthcare professionals.info:eu-repo/semantics/publishedVersio
