Behavioural observations were used to investigate the temporal dynamics events and associated variation in the daily activities of a sedentary population of mallard duck (
Anas platyrhynchos
) ...inhabiting an urban park in northern Portugal. Data was collected at Porto City Park from December to April, during the species’ courtship and early nesting periods. The most frequent activities for this population were locomotion, resting and feeding. Statistical analysis revealed that male and female behaviours differed significantly throughout the courtship period, as males exhibited more displays and aggressive behaviour while females were more prone to feed in order to meet their increased nutritional and energetic needs. Temporal analyses showed that courtship reached a peak in intensity in February, since it was in this month that the highest values for mating, aggressive behaviour in males and defensive behaviour in females were observed. Behavioural differences were found for this population, with higher feeding rates compared to those of wild populations as well as lower defensive behaviour rates. This paper sheds light on how synanthropized populations, as well as those from Southwestern Europe, show different behavioural responses from other populations. Additional extensive monitoring of population dynamics and factors such as latitudinal differences, habituation to humans and climate change will help to predict future growth and expansion rates.
Dog training methods range broadly from those using mostly positive punishment and negative reinforcement (aversive-based) to those using primarily positive reinforcement (reward-based). Although ...aversive-based training has been strongly criticized for negatively affecting dog welfare, there is no comprehensive research focusing on companion dogs and mainstream techniques, and most studies rely on owner-reported assessment of training methods and dog behavior. The aim of the present study was to evaluate the effects of aversive- and reward-based training methods on companion dog welfare within and outside the training context. Ninety-two companion dogs were recruited from three reward-based schools (Group Reward, n = 42), and from four aversive-based schools, two using low proportions of aversive-based methods (Group Mixed, n = 22) and two using high proportions of aversive-based methods (Group Aversive, n = 28). For evaluating welfare during training, dogs were video recorded for three sessions and six saliva samples were collected, three at home (baseline levels) and three after training (post-training levels). Video recordings were used to examine the frequency of stress-related behaviors (e.g., lip lick, yawn) and the overall behavioral state of the dog (e.g., tense, relaxed), and saliva samples were analyzed for cortisol concentration. For evaluating welfare outside the training context, dogs participated in a cognitive bias task. Results showed that dogs from Group Aversive displayed more stress-related behaviors, were more frequently in tense and low behavioral states and panted more during training, and exhibited higher post-training increases in cortisol levels than dogs from Group Reward. Additionally, dogs from Group Aversive were more 'pessimistic' in the cognitive bias task than dogs from Group Reward. Dogs from Group Mixed displayed more stress-related behaviors, were more frequently in tense states and panted more during training than dogs from Group Reward. Finally, although Groups Mixed and Aversive did not differ in their performance in the cognitive bias task nor in cortisol levels, the former displayed more stress-related behaviors and was more frequently in tense and low behavioral states. These findings indicate that aversive-based training methods, especially if used in high proportions, compromise the welfare of companion dogs both within and outside the training context.
Abstract
Background
In Mozambique, socio-economic and cultural factors influence the wide adoption of disease preventive measures that are relevant for malaria control strategies to promote early ...recognition of disease, prompt seeking of medical care, sleeping under insecticide-treated nets (ITNs), and taking intermittent preventive treatment for pregnant women. However, there is a critical information gap regarding previous and ongoing malaria social and behavioural change (SBC) interventions. The aim of this study is to assess the knowledge, attitudes, practices of beneficiaries of SBC interventions.
Methods
A descriptive cross-sectional survey was undertaken in 2018 in two rural districts of Zambezia Province, Mozambique. A structured questionnaire was administered to 773 randomly selected households. Respondents were the adult heads of the households. Descriptive statistics were done.
Results
The main results show that 96.4% of respondents recalled hearing about malaria in the previous 6 months, 90.0% had knowledge of malaria prevention, and 70.0% of preventive measures. Of the 97.7% respondents that had received ITNs through a mass ITN distribution campaign, 81.7% had slept under an ITN the night before the survey. In terms of source of health information, 70.5% mentioned the role of community volunteers in dissemination of malaria prevention messages, 76.1% of respondents considered worship places (churches and mosques) to be the main places where they heard key malaria prevention messages, and 79.1% asserted that community dialogue sessions helped them better understand how to prevent malaria.
Conclusions
Results show that volunteers/activists/teachers played an important role in dissemination of key malaria prevention messages, which brought the following successes: community actors are recognized and people have knowledge of malaria transmission, signs and symptoms, preventive measures, and where to get treatment. There is, however, room for improvement on SBC messaging regarding some malaria symptoms (anaemia and convulsions) and operational research is needed to ascertain the drivers of malaria prevalence and inform the SBC approach.
This study aimed to evaluate a clothing prototype that incorporates sensors for the evaluation of pressure, temperature, and humidity for the prevention of pressure injuries, namely regarding ...physical and comfort requirements. A mixed-method approach was used with concurrent quantitative and qualitative data triangulation. A structured questionnaire was applied before a focus group of experts to evaluate the sensor prototypes. Data were analyzed using descriptive and inferential statistics and the discourse of the collective subject, followed by method integration and meta-inferences. Nine nurses, experts in this topic, aged 32.66 ± 6.28 years and with a time of profession of 10.88 ± 6.19 years, participated in the study. Prototype A presented low evaluation in stiffness (1.56 ± 1.01) and roughness (2.11 ± 1.17). Prototype B showed smaller values in dimension (2.77 ± 0.83) and stiffness (3.00 ± 1.22). Embroidery was assessed as inadequate in terms of stiffness (1.88 ± 1.05) and roughness (2.44 ± 1.01). The results from the questionnaires and focus groups' show low adequacy as to stiffness, roughness, and comfort. The participants highlighted the need for improvements regarding stiffness and comfort, suggesting new proposals for the development of sensors for clothing. The main conclusions are that Prototype A presented the lowest average scores relative to rigidity (1.56 ± 1.01), considered inadequate. This dimension of Prototype B was evaluated as slightly adequate (2.77 ± 0.83). The rigidity (1.88 ± 1.05) of Prototype A + B + embroidery was evaluated as inadequate. The prototype revealed clothing sensors with low adequacy regarding the physical requirements, such as stiffness or roughness. Improvements are needed regarding the stiffness and roughness for the safety and comfort characteristics of the device evaluated.
Abstract Aiming to translate, culturally adapt, and psychometrically evaluate the Person-centred Practice Inventory - Staff (PCPI-S) for Portuguese healthcare professionals, this methodological study ...was conducted sequentially in two phases. Phase I followed the 10-steps recommendations from the ISPOR taskforce for translation and cultural adaptation of patient reported outcome measures. Phase II comprised a quantitative cross-sectional virtual survey of the translated PCPI-S with healthcare professionals, who were reached through snowball sampling from both primary and specialized care settings. The psychometric properties of the PCPI-S were determined by assessing reliability and construct validity. A sample of 304 healthcare professionals participated in Phase II. Ceiling effects were found. The overall internal consistency was excellent (> 0.9). The confirmatory factor analysis showed a good model fit after minor modifications, revealing construct validity, and supporting the theoretical framework. In conclusion, the three-factorial model of PCPI-S adjusted to the studied sample is a valid and reliable instrument to assess the perceptions of healthcare professionals on person-centred practice in various Portuguese clinical contexts. Considering the ceiling effects, the effect of social desirability should be explored.

A Fase I seguiu as recomendações de dez etapas da taskforce da ISPOR para tradução e adaptação cultural de medidas de resultados auto reportados. A Fase II incluiu um estudo cross-sectional do PCPI-S traduzido com profissionais de saúde, que foram alcançados por meio de amostragem snowball em contextos de cuidados primários e diferenciados. A psicometria do PCPI-S foi analisada pela avaliação da confiabilidade e validade de construto. Uma amostra de 304 profissionais de saúde participou da Fase II. Efeitos de teto foram encontrados. A consistência interna geral foi excelente (> 0,9). A análise fatorial confirmatória mostrou um bom ajuste do modelo e validade de construto, refletindo o referencial teórico. Concluindo, o modelo tri-fatorial do PCPI-S ajustado à amostra estudada é um instrumento válido e fiável para avaliar as percepções dos profissionais de saúde sobre a prática centrada na pessoa em vários contextos de cuidados portugueses. Considerando os efeitos teto, a desejabilidade social deve ser explorada.
The measurement of hair cortisol is increasingly used to understand the effect of natural and anthropogenic stressors on wild animals, but it is potentially confounded by individual, seasonal and ...sex-dependant variations in baseline cortisol secretion. This study validated an enzyme-linked immunoassay for hair cortisol measurement and characterized its baseline variation in a wild population of Egyptian mongoose. The analysis encompassed individuals of both sexes and all ages, across a range of geographic, environmental and seasonal conditions that the species experiences in Portugal allowing us to account for spatial, temporal and biological factors that contribute to hair cortisol variation. Our results showed that age, sex and storage time had an effect on hair cortisol, but season did not. Hair cortisol was higher in early stage juveniles compared to other age cohorts, in males when compared to females, and decreased with longer storage time. By identifying the factors that influence baseline hair cortisol in this wild population, we establish the basis for its application as an indicator of the effect of natural and anthropogenic stressors.
Dogs’ capacity to ‘catch’ human yawns has recently attracted the attention of researchers in the field of animal cognition. Following recent studies suggesting that contagion yawning in humans, and ...some other primates, is empathy-related, some authors have considered the possibility that the same mechanism may underlie contagious yawning in dogs. To date, however, no positive evidence has been found, and more parsimonious hypotheses have been put forward. The present study explored the ‘contagion-only’ hypothesis by testing whether the mere sound of a human yawn can be sufficient to elicit yawning in dogs, in a way that is unaffected by social–emotional factors. Unexpectedly, results showed an interesting interplay between contagion and social effects. Not only were dogs found to catch human yawns, but they were also found to yawn more at familiar than unfamiliar yawns. Although not allowing for conclusive inferences about the mechanisms underlying contagious yawning in dogs, this study provides first data that renders plausible empathy-based, emotionally connected, contagious yawning in these animals.
Resumo: Atualmente os cidadãos são parceiros dos sistemas formais na promoção da saúde. Na gestão das doenças hereditárias, o papel dos familiares como fonte de suporte é vital. O papel dos mais ...velhos emerge como crucial pela longa relação com a doença e com os doentes na família. Contudo, esse papel permanece pouco explorado, em particular, em doenças genéticas, como a paramiloidose. Este estudo qualitativo exploratório analisa o papel dos mais velhos, em famílias com paramiloidose, na promoção da saúde dos mais novos. Adotou-se a técnica dos incidentes críticos, aplicada por entrevista semiestruturada. O estudo envolve 18 participantes que relataram 76 incidentes críticos. As entrevistas foram gravadas e submetidas a análise de conteúdo. Os principais resultados sugerem os seguintes papéis dos mais velhos junto dos mais novos: modelar (comportamentos), encorajar, informar e apoiar. As gerações mais velhas podem ser envolvidas pelos profissionais de saúde como parceiras no apoio aos mais novos em famílias com paramiloidose.
Abstract: Citizens are now partners in the formal health promotion system. In the management of hereditary diseases, the role of family members is a vital source of support. Elders play a crucial role due to their long relationship with the disease and with patients in the family. However, this role has still been insufficiently explored, particularly in genetic disorders like paramyloidosis. This exploratory qualitative study analyzes the role of elders in families with paramyloidosis, in health promotion for younger members. The critical incidents technique was applied using a semi-structured interview. The study involved 18 participants who reported 76 critical incidents. The interviews were taped and submitted to content analysis. The principal results suggest the following roles for elders with younger family members: act as role models (in behaviors), encourage, inform, and support. The older generations can be mobilized by health professionals as partners to support younger generations in families with paramyloidosis.

Introduction: Oesophageal cancer causes dysphagia and weight loss. Malnutrition further worsens with multimodal treatment. Aim: The aim of the study was to evaluate the impact of percutaneous ...endoscopic gastrostomy (PEG) placement in the nutritional status of patients with oesophageal cancer requiring chemoradiotherapy (CRT). Methods: A comparative study with a prospective arm and a historical cohort was conducted. Oesophageal cancer patients undergoing CRT with dysphagia grade >2 and/or weight loss >10% were submitted to PEG-tube placement (pull method) before CRT. Stoma seeding was evaluated through a swab obtained after placement and, in surgical patients, the resected stoma. A matched historical cohort without PEG placement was used as control (trial ACTRN12616000697482). Results: Twenty-nine patients (intervention group, IG) were compared to 30 patients (control group, CG). Main outcomes did not differ in the IG and CG: weight loss during CRT 8.1 ± 5.5 kg versus 9.1 ± 4.2 kg (p = 0.503); 6-month mortality after CRT or surgery 17.2% versus 26.7% (p = 0.383); perioperative complication rate 54.5% versus 55.6% (p = 1.000); unplanned hospital admissions 34.5% versus 40.0% (p = 0.661). In the CG, during CRT, 14 (46.7%) patients presented with dysphagia grade 3–4, of whom 12 required nasogastric tube feeding (n = 10), surgical gastrostomy (n = 1), and oesophageal dilation (n = 1). In the IG, 89.7% used the PEG tube during CRT, sometimes exclusively in 51.7%. Adverse events were mainly minor (n = 12, 41.4%), mostly late peristomal infections, 1 major complication (exploratory laparotomy due to suspected colonic interposition, not confirmed). There was no cytological or histological evidence of stomal tumour seeding. Conclusion: Weight loss, hospital admissions, surgical complications, and mortality were identical in oesophageal cancer patients referred for CRT, regardless of prophylactic PEG. However, half of the patients required exclusive enteral nutritional support, making PEG-tube placement an alternative to consider.
Enquadramento: Um número significativo de pessoas adultas tem um acesso venoso periférico difícil, o que leva a múltiplas tentativas de punção e ao esgotamento da rede venosa. A escala Venous ...International Assessment (VIA) é considerada a nível internacional como um instrumento fiável que classifica as vias de acesso venoso periférico das pessoas e determina o risco de complicações associadas. Objetivos: Traduzir, adaptar culturalmente e validar a Escala VIA para português europeu. Metodologia: Estudo da tradução, adaptação cultural, e avaliação das propriedades psicométricas da escala VIA em amostra não probabilística de 100 pessoas doentes a precisar de cateterização venosa periférica. Resultados: A versão em português europeu da escala VIA (EARV) revelou valores moderados de fiabilidade inter-observadores (k = 0,490; p < 0,0005). As validades do critério e do constructo da EARV foram avaliadas através de análise preditiva, convergente e correlacional, com magnitudes moderadas a grandes e significância estatística. Conclusão: A EARV é um instrumento fiável e válido que pode ajudar os profissionais de saúde portugueses na determinação e categorização de acessos venosos periféricos difíceis. Contudo, recomenda-se a realização de mais estudos para testar a aplicabilidade transversal desta escala.
