ExtractT h e electrocapacitance plethysmograph with local counterpressure was adapted for measurement of total blood flow and blood flow through the muscle and skin in 20 icteric preterm infants. Measurements were recorded from each infant, before and during phototherapy. In 10 infants in study I, the incubator was set to maintain skin temperature of 36.5" initially and during phototherapy and no attempt was made to alter the incubator settings. Total blood flow was found to increase by a mean of 116% due primarily to increased skin blood flow (224%) and to a lesser extent, muscle blood flow (35%). Concomitant increases in heart rate, respiration rate, skin and incubator temperature were found, but no change was observed in rectal temFerature. I n 10 infants in study 11, the skin temperature was kept constant at 36.5" before and during phototherapy by adjustment of incubator temperature. Significant increases, but of lesser magnitude, were observed in skin (52%) and total blood flow (37y0), whereas muscle blood flow remained unchanged. Rectal temperature fell by a mean of 0.6' and respiration rate and heart rate remained unchanged.
Background Palliative care program structure is important to integrating palliative services into cancer care. A first step in understanding the structure of palliative care programs is to survey existing programs. Method This data was generated from members of MASCC, the European Society of Medical Oncology (ESMO), and the European Association of Palliative Care (EAPC) who completed the surveys on the website. A survey questionnaire was developed using the survey tool developed by Dr. Hui and colleagues by permission which was modified for the purposes of this study. Findings were described in number and percentages. Inferential statistics involved the Fisher's exact test for factors with two levels, chi-Square test for unordered categorical factors with greater than two levels, CochranArmitage trend test for ordered categorical factors, and the Wilcoxon rank sum test for measured factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
