Selected ion flow tube-mass spectrometry (SIFT-MS) provides rapid, non-invasive measurements of a full-mass scan of volatile compounds in exhaled breath. Although various studies have suggested that breath metabolites may be indicators of human disease status, many of these studies have included few breath samples and large numbers of compounds, limiting their power to detect significant metabolites. This study employed a least absolute shrinkage and selective operator (LASSO) approach to SIFT-MS data of breath samples to preliminarily evaluate the ability of exhaled breath findings to monitor the efficacy of dialysis in hemodialysis patients...

Mobile clinics have been used successfully to provide healthcare services to people in hard to reach areas around the world, but their use is sometimes controversial. There are advantages to using mobile clinics among rural underserved populations, and providing access to those who are vulnerable will improve health and decrease morbidity and mortality. However, some teams use inappropriate approaches to international service. For over 15 years, Azusa Pacific University School of Nursing has sponsored mobile clinics to rural northern Haiti with the aim to provide culturally sensitive healthcare in collaboration with Haitian leaders...

Improving the reproductive health of immigrant populations requires understanding the specific context of risk and need. As part of a field trial of the FemCap™, a woman-initiated cervical barrier contraceptive, we conducted postintervention focus group discussions (FGDs) with 20 women (five FGDs) of Haitian background, the majority of whom were born in Haiti and spoke Haitian Créole at home, at a community health center in south Florida. Participants discussed the role of religion and inequitable gender norms in Haitian traditions about family planning decisions and provided important insights into the gender-power nuances of their partnership dynamics vis à vis the use of female barrier methods...

Importance: As the minority population increases in the United States, the incidence of skin cancer has important public health consequences, including poor skin cancer outcomes, in part because of late-stage diagnosis. Therefore, it is important to identify obstacles in skin cancer prevention in these communities. Objective: To characterize skin cancer prevention and education needs in uninsured, minority, and immigrant communities in South Florida. Design, Setting, and Participants: At a large free medical clinic in Florida, a convenience sample of people completed a 23-question survey in English, Spanish, or Haitian Creole assessing their skin cancer risk perception, knowledge, sun protective behaviors and barriers, and desirable outreach methods...

The B7 gene family has crucial roles in the regulation of adaptive cellular immunity. In cancer, deregulation of co-inhibitory B7 molecules is associated with reduced antitumor immunity and cancer immune evasion. FDA approval of cancer immunotherapy antibodies against cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and programmed cell death-1 (PD-1)-both ligands of the B7 family-demonstrate the impact of these checkpoint regulators in cancer. Using data from cBioPortal, we performed comprehensive molecular profiling of the 10 currently known B7 family proteins in 105 different cancers...

Vulnerability is a central concept in humanitarian aid. Discussions of vulnerability in disaster response literature and guidelines for humanitarian aid range from considerations of a universal human vulnerability, to more nuanced examinations of how particular characteristics render individuals more or less at risk. Despite its frequent use, there is a lack of clarity about how vulnerability is conceptualized and how it informs operational priorities in humanitarian assistance. Guided by interpretive description methodology, we draw on the feminist taxonomy of vulnerability presented by Mackenzie, Rogers and Dodds (2014) to examine perspectives of 24 expatriate and Haitian decision-makers and health professionals interviewed between May 2012 and March 2013...

Two-dimensional (2D) nanoscale oxides have attracted research interest owing to their electronic, magnetic optical and catalytic properties. If they could be manufactured on a large scale, 2D oxides would be attractive for applications ranging from electronics to energy conversion and storage. Herein, we report facile fabrication of oxide nanosheets by rapid thermal annealing of corresponding hydrous-chloride compounds. By heating CrCl3·6H2O, ZrOCl2·8H2O, AlCl3·6H2O and YCl3·6H2O crystals as precursors, we immediately collect large quantities of ultrathin Cr2O3, ZrO2, Al2O3 and Y2O3 nanosheets, respectively...

(-)-Hydroxycitric acid (HCA) suppresses fatty acid synthesis in animals, but its biochemical mechanism in poultry is unclear. This study identified the key proteins associated with fat metabolism and elucidated the biochemical mechanism of (-)-HCA in broiler chickens. Four groups (n = 30 each) received a diet supplemented with 0, 1000, 2000 or 3000 mg/kg (-)-HCA for 4 weeks. Of the differentially expressed liver proteins, 40 and 26 were identified in the mitochondrial and cytoplasm respectively. Pyruvate dehydrogenase E1 components (PDHA1 and PDHB), dihydrolipoyl dehydrogenase (DLD), aconitase (ACO2), a-ketoglutarate dehydrogenase complex (DLST), enoyl-CoA hydratase (ECHS1) and phosphoglycerate kinase (PGK) were upregulated, while NADP-dependent malic enzyme (ME1) was downregulated...
