Feeding protocol for the Amazonian ornamental cichlid Apistogramma cacatuoides and a histological approach to the nutritional condition of larvae.

The aim of this study was to develop a feeding protocol for the larviculture of Apistogramma cacatuoides, using the histological approach to larval nutrition conditions. For this, three experiments were carried out. Experiment 1 was carried out in a randomized design to determine the optimal amount of Artemia nauplii (AN) per larva, and three treatments were evaluated: P1-feeding with 25 A. nauplii per larva (AN/L) during the first 5 days, followed by 50 AN/L from the 6th to the 10th day and 100 AN/L from the 11th to the 20th day; P2 and P3-37 and 50 AN/L during the first 5 days, 75 and 100 AN/L from the 6th to the 10th day and 150 and 200 AN/L from the 11th to the 20th day. Experiment 2 was carried out in a randomized design to determine the daily frequency of feeding and evaluated four feeding frequencies: F1-feeding only once a day (09:00); (F2)-feeding twice a day (09:00 and 17:00); F3-feeding three times a day (09:00, 11:30 and 17:00); and F4-feeding four times a day (09:00, 11: 30, 14:00 and 17:00). Experiment 3 lasted 40 days and was conducted in a randomized design to evaluate three periods for the beginning of the feeding transition: WE10:AN for 10 days, followed by 3 days of co-feeding and commercial feed until the end of the experimental period; WE15:AN for 15 days, followed by 3 days of co-feeding and commercial feed; WE20:AN for 20 days, followed by 3 days of co-feeding and commercial feed. The results of this study showed that, for the best development of the larvae, they should receive the feeding protocol 50-100-200 AN/L (P3) until the 20th day of exogenous feeding. From the 21st day, the transition to inert food should begin with 3 days of co-feeding, and feeding during larviculture should be carried out at a frequency of twice a day; this protocol provided a good nutritional status for the larvae, as shown by the histological approach.

Does Regular Exercise Impact the Lung Function of Healthy Children and Adolescents? A Systematic Review and Meta-Analysis.

PURPOSE: To assess the quality of the available evidence on the effect of exercise for the improvement of lung function in healthy children and adolescents. METHOD: We performed a systematic review and meta-analysis of intervention studies examining the effects of regular exercise on spirometric parameters of healthy children and adolescents aged ≤18 years. RESULTS: Within the exercise groups, there were significant improvements in forced vital capacity (mean difference: 0.17 L; 95% confidence interval, 0.07 to 0.26; P < .05) and forced expiratory volume in the first second (mean difference: 0.14 L; 95% confidence interval, 0.06 to 0.22; P < .05). Results were consistent across different age groups and duration of interventions. In the between-group analysis, forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow were higher in the exercise group compared with the nonexercise group, but the differences did not reach statistical relevance. There was significant statistical heterogeneity between studies. CONCLUSION: Regular exercise has the potential to improve lung function parameters in healthy children and adolescents; however, the small number of studies and the heterogeneity between them raise concern about the quality of the currently available evidence. These findings bring to attention the need for well-designed trials addressing this important public health issue.

Relationship of the nursing practice environment with the quality of care and patients' safety in primary health care.

BACKGROUND: Nursing practice environment has impact on the quality of nursing care and on patients' and nurses' outcomes, namely better performances of these healthcare workers. Improving the nursing practice environment is a low-cost organizational strategy to achieve better patients' outcomes and retain qualified nurses, thus improving nursing care of units, healthcare organizations and healthcare system. This study aims to analyse the relationship between nursing practice environment and the nurses` perception of quality of care, patient safety, and safety culture in Primary Health Care in Portugal. METHODS: We conducted a descriptive, analytical, and cross-sectional study using data from RN4CAST Portugal. The sample was composed of 1059 nurses from 55 Health Center Groups of the mainland Portugal, 15 Health Centers of the Autonomous Region of Madeira and 6 Health Centers of the Autonomous Region of the Azores. Multivariate analysis and correlation analysis methods were used for data processing. RESULTS: Nurses consider that, in the Portuguese Primary Health Care, there is a mixed and unfavourable nursing practice environment, with a perception of a good quality of care, and both acceptable patients' safety and safety culture. The Collegial Nurse-Physician Relations and Nursing Foundations for Quality of Care dimensions to have the best ratings. The perception of Primary Health Care nurses on the dimension Nurse Participation in Organization Affairs was the one that showed the lowest score, followed by Staffing and Resource Adequacy and Nurse Manager Ability, Leadership, and Support of Nurses. Based on perception of nurses, the relationship between the nursing practice environment and the safety culture is higher, followed by the quality of care and patients' safety. CONCLUSIONS: The perception of Primary Health Care nurses is that there is an unfavourable and mixed nursing practice environment, with good quality of care, and acceptable patient safety and safety culture. The quality of the nursing practice environments is associated to better quality and safety of care. Thus, improving the nursing practice environments in healthcare organizations is a low-cost organizational strategy to achieve greater patients and nurses' outcomes, improving the quality of nursing care to patients in the Primary Health Care units.

Gender differences in the development of childhood obesity in young teenagers in Murcia, Spain.

BACKGROUND: The number of overweight children is increasing at an alarming rate. This issue requires effective action plans, as childhood obesity has become a problem in which addressing environmental factors is decisive. Significant differences have also been shown in lifestyle habits that determine overweight based on sex. This study therefore aimed to examine these risk factors according to sex. METHODS: The sample included first-year high school students from Murcia, Spain. Information was collected through the "Questionnaire on Healthy Habits in Adolescents," validated for this age range, and the weight, height, and waist circumference of the participants were obtained. Data were analyzed through partial least squares structural equation modeling to determine which modifiable risk factors promoted the appearance of excess weight and in what magnitude. RESULTS: A total of 421 students participated in the study, and 40.6% of overweight patients were detected according to their body mass index. No differences were found between the sexes and weights. The environment and the use of new technologies that do not involve sitting were significant only in girls (P < 0.05). Conversely, physical activity was significantly higher in boys (P < 0.05). Dietary factors and sedentary activities did not differ according to sex. CONCLUSIONS: The social and school environment, the use of new technologies (for girls), and physical activity (for boys) condition nutritional status. Identifying gender disparities in behaviors that involve health should be a priority for new prevention programs. Targeting young people's health from a gender perspective has considerable potential to reduce overweight problems in adulthood.

Temperature-induced changes in reproductive variables in the teleost fish Lophiosilurus alexandri.

The present study evaluates whether increased water temperature induces reproduction by Lophiosilurus alexandri under controlled conditions, and investigates the effects of this procedure on sexual steroids, hematological profile and behavior. A 44-week experiment was performed with four wild males and 12 wild females that had been acclimatized to captive conditions. Water temperature was maintained at 24.4 ±â€¯1.0 °C for weeks 1-22, and then at 29.0 ±â€¯1.1 °C for weeks 22-44. Spawn weight, number of eggs/spawn and hatching rate were satisfactory and ranged 27.5-127.5 g, 1209-5183 and 83-89%, respectively. Hematocrit, leukocytes and glucose were not influenced by increased water temperature, while higher values for erythrocytes were observed for both sexes. The lowest value for plasma protein was for females maintained at 29.0 °C, while the lowest value for testosterone was obtained at the end of the study period at a temperature in 29.0 °C. Serum values of 17ß-estradiol were higher in females than in males, however, there was no evidence of variation as a function of experimental temperature or interaction with sex. The reproductive behavior of L. alexandri in captivity is described for the first time. The present study demonstrates that adult individuals are able to maintain a stable hematological profile during an increase in mean water temperature from 24.4 °C to 29.0 °C, even during the reproductive period, and still produce good quality larvae. Nonetheless, whether spawning was associated with increased 17ß-estradiol levels could not be determined.

Impact of Nurse Manager's Attributes on Multi-Cultural Nursing Teams: A Scoping Review.

BACKGROUND: As global migration increases, nurse managers' effectiveness in multi-cultural nursing work environments is crucial due to the rising cultural diversity within healthcare teams. Despite the increasing international recruitment of qualified nurses to address the worldwide nursing shortage, no studies have synthesised the impact of nurse managers' attributes on nurses in multi-cultural nursing teams. Therefore, it was conducted a literature review aimed to synthesise the available literature on how nurse managers' personality traits, competencies, behaviours, and leadership styles influence nurse outcomes in multi-cultural nursing teams. METHODS: Scoping review conducted according to the Joanna Briggs Institute guidelines to map the relationship or influence of nurse managers' personality traits, competencies, behaviours, and leadership styles on the outcomes of nurses in multi-cultural settings across various clinical environments. Searches were conducted across electronic databases such as CINAHL and MEDLINE, along with grey literature. RESULTS: This review included 39 studies, highlighting 29 personality traits, 9 competencies, 115 behaviours, and 5 leadership styles that impact nurses' outcomes. Key findings emphasise the importance of nurse managers being supportive, culturally competent, and effective communicators, with transformational leadership style being particularly beneficial. CONCLUSIONS: These findings provide insights for planning and developing training programmes to equip current and future nurse managers with skills to effectively lead in multi-cultural care settings.

Nurses' Well-Being at Work in a Hospital Setting: A Scoping Review.

The aim of this review was to analyze the scientific evidence about nurses' well-being at work in the hospital context. Well-being is present in our daily experiences, whether in a personal or professional context. Nurses are frequently put under pressure and stressed at work, which can influence their well-being. Nurses' well-being at work in a hospital setting is crucial due to its relevance to occupational health, the quality of patient care, and the identification of stress and satisfaction factors. Methods: This systematic review followed the methodological guidelines of the Joanna Briggs Institute (JBI). The databases searched included CINAHL, MEDLINE, Scopus, Cochrane Database of Systematic Reviews, LILACS, Scientific Electronic Library Online (SciELO), and the Open Access Scientific Repositories of Portugal (RCAAP). The following inclusion criteria were defined: studies in Portuguese or English; with abstracts or full texts available; with a publication date from 2018 to 2022; and research containing the identified keywords in the title (TI) or abstract (AB). To organize and synthesize the data, we used a table to extract the significant information from each included study. Results: Eight studies were included, all of them emphasizing the assessment of well-being at work and the manager's intervention to promote this well-being. We found that most studies indicate that nurses are satisfied with their work. There are several factors that can influence this positive level of well-being at work, such as interaction with management, culture, and organizational commitment. It can be concluded that nurse managers have a decisive role in promoting well-being at work.

Mapping Strategies for Strengthening Safety Culture: A Scoping Review.

BACKGROUND: Twenty years after the "To Err Is Human" report, one in ten patients still suffer harm in hospitals in high-income countries, highlighting the need to strengthen the culture of safety in healthcare. This scoping review aims to map patient safety culture strengthening strategies described in the literature. METHOD: This scoping review follows the JBI methodology. It adhered to all scoping review checklist items (PRISMA-ScR) with searches in the Lilacs, MedLine, IBECS, and PubMed databases and on the official websites of Brazilian and North American patient safety organizations. The research took place during the year 2023. RESULTS: In total, 58 studies comprising 52 articles and 6 documents from health organizations were included. Various strategies were identified and grouped into seven categories based on similarity, highlighting the need for a comprehensive organizational approach to improve patient care. The most described strategies were communication (69%), followed by teamwork (58.6%) and active leadership (56.9%). CONCLUSION: The identified strategies can promote the development of a culture in which an organization can achieve patient safety, involving practices and attitudes that reduce risks and errors in healthcare. However, the identification of strategies is limited because it is restricted to certain databases and websites of international organizations and does not cover a broader spectrum of sources. Furthermore, the effectiveness of these strategies in improving patient safety culture has not yet been evaluated.

Translation, Adaptation, and Validation of the Portuguese Version of the Exercise of Self-Care Agency Scale.

Assessing a person's capacity to engage in self-care behaviours is another added value in identifying one's potential to care for oneself in the health domain that contributes to planning person-centred care. This study aimed to translate, adapt, and validate the Exercise of Self-Care Agency (ESCA) Scale by Kearney and Fleischer, revised by Riesch and Hauck for the Portuguese version, using a sample of 625 elderly people living at home in Portugal. A cross-cultural adaptation process follows the stages of translation, synthesis, back-translation, and consensual solution for the translation process and pretesting. Construct validity was tested using exploratory factor analysis, and factor structure was subjected to confirmatory factor analysis. Reliability was determined by analysing internal consistency, resorting to Cronbach's alpha coefficient. This resulted in an instrument formed of 29 items, keeping the factor structure conceptually aligned with the underlying theory. Cronbach's alpha coefficient values were 0.87 for the global scale and varied between 0.65 and 0.84 for the subscales. The final four-factor model showed an acceptable quality of fit. The Portuguese version of the ESCA shows appropriate validity and reliability for use in future research and health contexts.

Cross-Cultural Validation of the Portuguese Version of the Quality of Oncology Nursing Care Scale.

BACKGROUND: Quality assessment in oncology nursing care has been a growing topic in the literature, gaining relevance as oncological nursing care becomes more complex as the science progresses. However, there are no instruments that assess the perception of the quality of oncology nursing care from the point of view of patients for the Portuguese population. Thus, the cross-cultural translation and validation of the Quality of Oncology Nursing Care Scale (QONCS) was performed for the Portuguese context. This instrument allows nurses to assess patients' self-perception of the quality of nursing care provided in an oncological setting. It also allows researchers to compare the results obtained internationally with the application of this scale. METHODS: This is a methodological study, with two distinct phases: the first corresponded to the translation and cultural adaptation of the scale to the Portuguese context, and the second consisted of the psychometric validation of the QONCS, which included factor analysis and the evaluation of the psychometric properties of the instrument. We obtained responses from 402 patients from a Portuguese oncology hospital. RESULTS: The Portuguese version of the Quality of Oncology Nursing Care Scale (QONCS_PT) consists of 34 items inserted into a tetra-factorial model, which explains a total variance of the instrument of 69.8%. A Cronbach's alpha of 0.93 was obtained for the complete instrument. CONCLUSIONS: QONCS_PT has a competent and reliable structure. The scale's validity was assured and can be used in the Portuguese population, as it is useful for direct care provision but also for researchers and managers.
