RESUMO
BACKGROUND: Young children who stay with their families in homeless shelters face chronic challenges related to extreme poverty and acute risks from stressful events surrounding the loss of housing and move to shelter. These adversities increase the likelihood of a range of poor developmental outcomes. Consistent with the risk and resilience perspective, however, many children who experience family homelessness succeed, functioning as well or better than their non-homeless peers. As such, efforts to support resilience should consider how best to enhance protective factors, such as supportive environments within shelter settings. METHODS: With data from 60 caregivers of children ages birth to 5 years recruited from family shelters, we assessed caregivers' perceptions of community support as well as child and family well-being in terms of recent adverse experiences, parenting stress, access to social support, and child social-emotional functioning. RESULTS: Many caregivers experiencing family homelessness perceived negative aspects of the shelters where they were staying with their children. Furthermore, children whose caregivers had more negative perceptions of the shelter environment displayed worse social-emotional functioning, even when accounting for differences in parenting stress, recent family adversity, and other sources of social support. CONCLUSIONS: Because young children rely on their caregivers as primary resources for nurturance and support, we encourage family homelessness service providers to work in partnership with caregivers to create more inclusive and empowering practices within the shelter context. Doing so is likely to improve children's developmental outcomes and the overall well-being of the families.

PURPOSE: In a model of fat embolism using triolein-treated rats, we have reported that the acute pulmonary histopathological changes at 48 hrs were ameliorated by the angiotensin AT1 receptor blocker losartan, the angiotensin converting enzyme inhibitor captopril, and the direct renin inhibitor aliskiren. Although much of the pathology had declined by 3 weeks, the changes persisted at 6 weeks. The purpose of the study was to extends the time course investigation to 10 weeks and to examines whether the fat embolism effects continue to be blocked by losartan when given at a late time period. MATERIALS AND METHODS: Unanesthetized rats were challenged with i.v. triolein or saline. After 6 weeks, one group received saline or losartan i.p. and the losartan group also received losartan in the drinking water. At 10 weeks, the experiment was terminated. RESULTS: Confirming previous results, the fat embolism group showed normal weight gain at 6 weeks without apparent distress and also appeared normal at 10 weeks. However, at 10 weeks the lungs showed inflammatory and fibrotic changes that were greater than those found at 6 weeks. These changes were reduced by losartan. CONCLUSIONS: These findings show that the effects of fat embolism continue to progress to 10 weeks after the initial insult with triolein. The fact that the protective effects of losartan treatment started at 6 weeks supports the involvement of the renin-angiotensin system in late as well as early stages of the histopathological changes following fat embolism. It also supports the use of angiotensin blockade in clinical situations even long after an initial trauma where fat embolism is suspected.
