[Show abstract][Hide abstract] ABSTRACT: Every year approximately half a million hectares of land are burned by wildfires in southern Europe, causing large ecological and socio-economic impacts. Climate and land use changes in the last decades have increased fire risk and danger. In this paper we review the available scientific knowledge on the relationships between landscape and wildfires in the Mediterranean region, with a focus on its application for defining landscape management guidelines and policies that could be adopted in order to promote landscapes with lower fire hazard. The main findings are that (1) socio-economic drivers have favoured land cover changes contributing to increasing fire hazard in the last decades, (2) large wildfires are becoming more frequent, (3) increased fire frequency is promoting homogeneous landscapes covered by fire-prone shrublands; (4) landscape planning to reduce fuel loads may be successful only if fire weather conditions are not extreme. The challenges to address these problems and the policy and landscape management responses that should be adopted are discussed, along with major knowledge gaps.

[Show abstract][Hide abstract] ABSTRACT: We report twin neonates who were born prematurely at 32 weeks of gestation to a mother with human immunodeficiency virus infection. One of the twins developed complete heart block and dilated cardiomyopathy related to lopinavir/ritonavir therapy, a boosted protease-inhibitor agent, while the other twin developed mild bradycardia. We recommend caution in the use of lopinavir/ritonavir in the immediate neonatal period.
[Show abstract][Hide abstract] ABSTRACT: For neonates identified as at increased risk of acquiring HIV perinatally, the optimal postnatal prophylaxis regimen is not known. Current United States Public Health Service guidelines recognize that combination postnatal prophylaxis may be considered in some situations but that there are little data regarding the effectiveness and safety of any postnatal regimen besides zidovudine. The actual use of combination postnatal regimens in the United States has not previously been described. We conducted a national, Web-based survey between December 2009 and January 2010 to describe the percent of providers who prescribe combination postnatal prophylaxis, the antiretroviral combinations they used, and the risk factors that might elicit combination postnatal prophylaxis. 472 known or possible perinatal HIV providers were queried; 42% (n = 197) responded and 68% of respondents (134) were eligible to complete the survey. Sixty-two percent (n = 83) of participating providers reported use or recommendation of combination postnatal prophylaxis in the last year. Three drugs, zidovudine, lamivudine and nevirapine, comprised 77% of first-choice combination regimens. Lopinivir-ritonivir (LPV/RTV) was included in 16% of all reported regimens. Combination postnatal prophylaxis was strongly preferred in patient-based scenarios with additional risk factors for perinatal HIV transmission.
