Review and Implications of Intergenerational Communication and Social Support in Chronic Disease Care and Participation in Health Research of Low-Income, Minority Older Adults in the United States.

Health disparities disproportionally affect Black and Hispanic older US adults. Health research is needed to understand and eliminate these disparities; however, older adults, and particularly Black and Hispanic/Latino older adults are underrepresented in health research. Adult children have influenced health behavior and health outcomes of their older parents in several demographics in the US.

Morphine determination by gas chromatography/mass spectroscopy in human vitreous humor and comparison with radioimmunoassay.

A gas chromatographic-mass spectroscopic method (GC/MS) for morphine determination in human vitreous humor was developed. Reversed-phase solid-liquid extraction gave better sample purification compared with liquid-liquid or normal-phase solid-liquid extractions. In 10 real cases of death by heroin overdose, the correlation between the results obtained by GC/MS and by radioimmunoassay (RIA) was studied.

[Plasma dehydroepiandrosterone sulfate and urine steroid excretion in hepatic cirrhosis].

In the present study we evaluated the alterations of plasma levels of dehydroepiandrosterone sulphate (DHEA-S) and of steroid-derivatives urinary excretion in cirrhotic patients compared with normal controls. 107 patients have been studied: 45 affected by liver cirrhosis (22 males and 23 females) both in compensated and in ascitic state, and 62 healthy controls (32 males and 30 females). In all patients we assayed plasma DHEA-S by RIA as well as common liver function tests; moreover gaschromatographic profile of adrenal steroid excretion was performed in daily urine.
