Background: This study intended to implement a novel intervention strategy, in Brazil, using an ecohealth approach and analyse its effectiveness and costs in reducing Aedes aegypti vector density as well as its acceptance, feasibility and sustainability. The intervention was conducted from 2012 to 2013 in the municipality of Fortaleza, northeast Brazil.
Methodology: A cluster randomized controlled trial was designed by comparing ten intervention clusters with ten control clusters where routine vector control activities were conducted. The intervention included: community workshops; community involvement in clean-up campaigns; covering the elevated containers and in-house rubbish disposal without larviciding; mobilization of schoolchildren and senior inhabitants; and distribution of information, education and communication (IEC) materials in the community.
Results: Differences in terms of social participation, commitment and leadership were present in the clusters. The results showed the effectiveness of the intervention package in comparison with the routine control programme. Differences regarding the costs of the intervention were reasonable and could be adopted by public health services.
Conclusions: Embedding social participation and environmental management for improved dengue vector control was feasible and significantly reduced vector densities. Such a participatory ecohealth approach offers a promising alternative to routine vector control measures.

Weaning impact: Evaluating growth, behavior, and production performance in Sahiwal cows and their calves.

Initial periods of life, beginning before birth and lasting until weaning are characterised by the greatest neural plasticity. Early postnatal stress causes lasting changes in a variety of behaviours as well as stress reactivity. Cow-calf contact for an extended period is believed to improve the social skills of calves and has also been linked to improved productivity of mothers.

Nitrogen single and multiple breath washout tests are sensitive in assessing peripheral airway function, and lung imaging detects structural abnormalities, but little is known about their use in paediatric cancer patients and survivors. We aimed to 1) identify studies using nitrogen single or multiple breath washout tests and/or lung imaging to assess pulmonary toxicity in paediatric cancer patients and survivors, and 2) describe reported abnormalities.

In the context of population ageing, the age-friendliness of neighborhood built environment (NBE) is increasingly recognized as essential for enabling ageing in place. However, while much research has focused on the impact of NBE on the physical health of older adults, its relationship with mental health (MH) remains underexplored, especially the pathways through which NBE indicators influence MH. This study measured NBE using ten indicators across three categories: daily travel (including barrier-free travel, elevator, rest seat, diversion of pedestrian and vehicle, road surface and public toilet), healthcare services (including public canteen and elderly care), and social participation (including outdoor fitness space and indoor activity space).

Background: The literature underscores the prevalence of pain as the most common presenting symptom in the Emergency Care Setting (ECS) and is associated with anxiety and stress for children. On top of that painful procedures are often required as part of their treatment, making procedural pain a common experience. The substantial evidence supporting the effectiveness of distraction-based interventions (DBI) in relieving pain and anxiety and reducing stress underscores the urgency of addressing this issue.
