The Medicaid Home and Community-Based Waiver and supported employment.

The Medicaid Home and Community-Based (HCB) Waiver is the primary funding source for long-term care for individuals with developmental disabilities. Findings from a national survey of 48 state coordinators regarding waiver-funded supported employment services are presented. Very low utilization for this service was found, primarily due to limits on eligibility. However, respondents in 18 states reported large numbers of waiver participants receiving employment services under other service categories. Eleven states had waiting lists for waiver-funded supported employment, totalling three times those actually receiving services. Low reimbursement rates to provider agencies and disinterest of providers in using waiver funds were significant barriers to expansion of service capacity.

Metabolic and hormonal responses to lipid and carbohydrate diets during exercise in man.

Nine healthy subjects were studied to determine their performance and the metabolic and hormonal responses to prolonged exercise after ingestion of a carbohydrate or a lipid diet. Subjects exercised on a bicycle ergometer (60% VO2max) until exhaustion four times at weekly intervals. The exercise test was performed 1 h after ingestion of three different isocaloric meals (400 Kcal) containing either glucose, medium-chain triglycerides (MCTs) or long-chain triglycerides (LCTs). The fourth test was performed after a night fast. The metabolism of these nutriments was followed using [U-13C]glucose, [1-13C]octanoate, and [1-13C]palmitate added as tracers. The average work time was comparable whatever nutriment used (116 +/- 11 min). Oxidation of the ingested nutriment over this period was 80% for glucose, 45% for MCTs, and 9% for LCTs. Glucose ingestion produced an early insulin peak associated at the end of the exercise with a lower glycemia compared to the fat diets. After MCT ingestion, an increase in ketone bodies was observed. Catecholamine response to physical exercise was decreased by all the meals when compared to fasting. Thus, we conclude that a different lipid meal, MCTs, or LCTs, compared to glucose feeding, do not modify exhaustion time in spite of differences in hormonal and metabolic responses.

[Determination of the percentage of grain whisky in commercial whiskies by isotopic mass spectrometry].

Commercial whisky is generally a blend between malt whisky and grain whisky. Corn is one of the main sources of grain and it is now well known that in corn the carbon dioxide assimilation proceeds through carboxylation of phosphoenolpyruvate but in many other plants like barley atmospheric carbon dioxide is fixed on ribulose 1,5 diphosphate. Each pathway of carbon dioxide assimilation is characterized by a fractionation factor of carbon isotopes. Consequently, the organic matter and also the fermentation alcohol of corn or barley show different 13C/12C ratio. The determination of the 13C/12C ratio in the alcohol of blended whisky allows the determination of the percentage of corn whisky.

[High-performance liquid-liquid chromatography in beverage analysis].

Liquid liquid chromatography was performed with columns packed with stationary phases chemically bonded to silica microparticules. These columns show a high efficiency and are used very easily. Flavouring compounds like aromatic aldehydes which have a low volatility were analyzed in brandy using a polar phase alkylnitrile. Sapid substances like amarogentin in Gentiana lutea or glyryrrhizin in Glycyrrhiza glabra were determined by reversed phase chromatography. Finally ionizable substances like synthetic dyes can be analyzed by paired ion chromatography witha non polar stationary phase.

[Use of ethanol naturally enriched in carbon 13 for metabolic studies].

The ratio of carbon 13 to carbon 12 is higher in organic substances which originate from corn or cane, as compared to most higher plants. Cane alcohol or corn alcohol are enriched in carbon 13 as compared to common European foods. This discovery provided a new technique for alcohol metabolism studies with animals or men. The ratio of carbon 13 to carbon 12 is measured by mass spectrometry in the carbon dioxide expired after administration of cane or corn alcohol. This ratio increases significantly and reaches a maximum when the blood alcohol level has decreased considerably.
