BackgroundThe potential role of Community Health Workers (CHWs) in improving maternal and child health outcomes, particularly in low and middle-income countries and in disadvantaged communities, is receiving increased attention. Adequate and focused training is among the key requisites for enhancing CHWs performances and research is necessary to identify effective training methods.MethodsA randomized controlled study was designed to assess the effectiveness of a training course in improving knowledge, attitudes and practices (KAP) of CHWs regarding maternal and infant health. Seventy-eight CHWs belonging to Family Health Units in the city of Recife, Brazil were randomly allocated to intervention and control groups. The intervention group took part in a four-day interactive training course based on an action-oriented guide to perform home visits to pregnant women and their infants throughout pregnancy and infancy until 9 months of age. KAP in intervention group after training and after 1 year were compared to control group and to baseline.ResultsFifty-nine CHWs completed all KAP assessments (31 in intervention and 28 in control group). Baseline characteristics were similar in both groups. At 1 year from training, the intervention group had higher overall KAP score (120.65 vs. 108.19, p < 0.001) as well as knowledge (47.45 vs. 40.54, p < 0.001), practice (53.45 vs. 49.11, p < 0.001) and attitudes scores (19.74 vs. 18.81, p = 0.047) than the control group. Moreover, at 1 year from training, the intervention group maintained significant improvements in overall KAP score (120.65 vs. 106.55, p < 0.001) as well as in knowledge (45.45 vs. 42.13, p < 0.001), and practice (53.45 vs. 45.29, p < 0.001) scores with respect to baseline. In the control group, overall KAP (106.59 vs. 108.19, p = 0.345) as well as separate knowledge, attitudes and practices scores remained unchanged.ConclusionsA four-day interactive training course on action-oriented home visits to pregnant women and infants produced a sustained improvement of CHWs’ KAP and may represent a model to ensure retention of acquired competences.Trial registrationRBR-9gchqr.

The Didelphidae are considered solitary opossums with few social interactions, usually limited to mating-related or mother-pouch young interactions. Anecdotal reports suggest that additional interactions occur, including den sharing by a few individuals, usually siblings. Here, we report novel observations that indicate opossums are more social than previously thought. These include nest sharing by males and females of Marmosa paraguayana, Gracilinanus microtarsus and Marmosops incanus prior to the onset of the breeding season and without signs of sexual activity; this is taken to indicate early pairbonding matching and cooperative nest building. We also recorded den sharing among recently weaned siblings of Didelphis aurita and Caluromys philander. In addition, we observed 13 individuals of Didelphis albiventris representing three age classes resting without agonistic interactions in a communal den. These are the first reports of gregarious behaviour involving so many individuals, which are either unrelated or represent siblings from at least two litters, already weaned, sharing the same den with three adults. Sociality in opossums is probably more complex than previously established, and field experimental designs combining the use of artificial nests with camera traps or telemetry may help to gauge the frequency and extent of these phenomena.
Objetivo: Avaliar o efeito de um programa de Visitas Domiciliares Inovadoras (VDI), que é baseado em um guia de orientação, nos conhecimentos e práticas de saúde das mães em relação aos cuidados da criança e durante os períodos pré/pós-natal, e indicadores de saúde materno-infantil (ISMI). Métodos: Estudo transversal e analítico que comparou 195 gestantes e mães que receberam VDI (grupo 1) com o grupo 2, de visitas domiciliares convencionais (VDC), realizado em Unidades de Saúde da Família (USF) de Recife, Pernambuco, entre 2015 a 2016. Dividiram-se 16 equipes de saúde da família em dois grupos: oito equipes receberam treinamento para VDI e oito não receberam. Houve dez VDI com a utilização do guia, durante a gestação e durante os nove meses da criança. As VDC ocorreram uma vez/mês, durante o mesmo período das VDI, mas sem o guia. Após nove meses, as participantes foram entrevistadas através de questionário com conteúdos relacionados à saúde materno-infantil. Resultados: 93 gestantes (49 do grupo 1 e 44 do 2) e 102 mães de crianças (57 do grupo 1 e 45 do 2) responderam aos questionários. Os resultados mostraram melhores indicadores de pré-natal (p=0,005), melhor conhecimento sobre métodos contraceptivos (p
