Background: Childhood obesity presents a significant public health concern globally, with implications for cardiovascular health and metabolic syndrome. In Portugal, approximately 31.6% of children are affected, highlighting the urgency for intervention strategies. This study aimed to assess the prevalence of overweight and obesity in Portuguese school-aged children, with a focus on sex and age differences. Methods: Anthropometric measurements were conducted on 1564 children aged 6–10 years, including weight, height, and skinfold thickness. Body Mass Index (BMI) and the percentage of body fat were calculated using established methods. Results: The results revealed significant differences in BMI (≤0.001) and body fat percentage (≤0.001) among different BMI categories, with a notable prevalence of overweight and obesity, particularly among boys. A total of 37% of the studied population is overweight or obese, among which 40.1% and 33.9% are boys and girls, respectively. Conclusions: This study highlights statistically significant differences in BMI and body fat percentage for both sexes in different BMI categories. A large proportion of the population is overweight or obese, with a greater prevalence in boys. In short, childhood obesity has a negative impact on body composition and is associated with significant differences in anthropometric parameters, emphasizing the importance of preventative and intervention strategies to address this health problem.

Argyrosomus regius (commonly referred to as meagre), is one of Europe's largest coastal bony fish species and supports important recreational and commercial fisheries in the Atlantic and Mediterranean coasts. Demand for this species, and more recently for their swim bladders, has led to regional population declines and growing importance as an aquaculture species. Despite intense research in captivity, little is known about the spatial ecology of A. regius's wild population, including basic information such as vertical migrations and depth/temperature preferences. Previous research based on indirect data suggests a seasonal habitat shift from shallow to deeper waters, but this has never been validated through direct high-resolution movement data. In this study, we tagged 13 adult A. regius with pop-up satellite archival tags in the South of Portugal, which successfully returned data from 11 individuals including high-resolution data from six recovered tags (mean, range: 167 days, 28–301 days). We found that adults of this population spend 95.2% of their time between 5 and 75 m depth (mean ± SD, 30.9m ± 18.3m) and do not venture beyond 125 m. Across seasons, A. regius move across water temperatures between 13.3 and 24.8°C with a preferred thermal range between 14 and 18°C where they spent 75.4% of their time. The inferential modelling using this electronic data validated previous hypotheses by showing significant differences between a shallower and warmer summer habitat vs. a deeper and cooler winter habitat. Visual investigation of the diel effects on depth preferences suggests subtle changes in depth use between day and night during the warmer months of the year. We speculate that these patterns are in response to the species' behavioural ecology and physiology, reflecting the seasonal changes in water stratification and presence of prey, as well as on the species reproduction, which results in summer spawning aggregations in shallower areas.

Rationale, Aims, and Objectives: The prevalence of burnout among medical doctors and its negative effect on empathy can influence therapeutic success. The aim of this study was to compare the levels of empathy and burnout between residents and specialists as well as to study the correlation between empathy and burnout. Methods: This is an exploratory study of a convenience sample of 104 doctors who work in health institutions in Greater Lisbon area in Portugal, covering central hospitals, district hospitals, and health centres. Each doctor filled in a questionnaire, which included the Maslach Burnout Inventory (MBI) and the Jefferson Scale of Empathy (JSE). Results: Participants were divided in two subgroups: 51% residents (n = 53) and 49% specialists (n = 51). A difference (p =.048) in JSE scores between residents (mean 116.4, SD 12.8) and specialists (mean 120.78, SD 12.84) has been identified. Furthermore, in all three MBI subscales (emotional exhaustion, depersonalization, and lack of personal accomplishment), the group of residents showed significantly higher mean scores. In general, empathy scores showed an inverse relationship between depersonalization (r = –0.390, p <.0001) and lack of personal accomplishment (r = –0.447, p <.0001). Finally, we found that an increase in MBI level is associated with a decrease in empathy levels. Conclusion: Our findings suggest that there is a significant difference in burnout subscales scores between residents and specialists and that these have a negative correlation with empathy level. These exploratory results draw attention to the importance of preventing burnout in hospital and health care centres professionals, in particular in residents, through the implementation of individual and organizational structured measures.

Isolated marine protected areas (MPAs) may not be enough to sustain viable populations of marine species, particularly the many small coastal MPAs which resulted due to social, economic and political constraints. Properly designed MPA networks can circumvent such limitations due to their potential synergistic positive effects, but this crucial step is frequently obstructed by lack of baseline ecological information. In this paper, we use systematic conservation planning on European Nature Information System coastal habitat information available for Portugal to demonstrate how an ecologically coherent nation-wide MPA network can be designed. We used the software Marxan to obtain near optimal solutions for each of three pre-determined conservation targets (10%, 30% and 50% protection) while maintaining the cost of including conservation units as low as possible. Marxan solutions were subsequently optimized with MinPatch by keeping each MPA above a minimum size that reflects the existing information on habitat use by some key marine fishes. Results show that 10% protection for all habitats would only require a relativelly small increase in the number (from 6 to 10) and area (from 479 km² to 509 km²) of already existing MPAs in mainland Portugal whereas substantial increases would be required to achieve the 50% target. This rather simple approach offers the added benefit of allowing design improvement as more relevant ecological information becomes available, including deeper habitat mapping across the whole continental shelf, allowing a coherent, adaptive and inclusive optimal MPA network to be designed.

Introduction: The aim of this study is to characterize and assess work-family balance within the medical profession in Portugal., Material and Methods: This cross-sectional and exploratory study analyzed a sample of 181 doctors who are members of the Portuguese Catholic Doctors' Association. A qualitative survey with multiple-choice questions was applied in order to assess socioeconomic and working conditions as well as work-family balance. Descriptive and linear regression analyses were carried out., Results: Nearly 40% of the surveyed doctors negatively assessed the work-family balance within the private sector. As for the Portuguese National Health System, 73% negatively assessed the work-family balance within the public sector. More than half of those surveyed (56%) worked more hours than what they considered as harmful for their work-family balance and the vast majority was working at the limit or overtime. Data collected enabled us to associate a heavier workload with working in the emergency room, age and men. Moreover, it was observed that working more hours was not linked to having children or being married., Discussion: In our study, the three measures of work-family balance that the participants considered to be the most important were the possibility of flexible scheduling, part-time work and temporarily reducing working hours (e.g. for family assistance). These aspects may explain the differences found in the assessment of work-family balance between the public and private sector., Conclusion: Due to the demanding nature of the medical profession, doctors are placed into a particularly risky situation in order to achieve a suitable work-family balance. The results of our study indicate a general dissatisfaction regarding this balance - special in the public sector - which is mainly associated with excessive weekly working hours.
