Sex-related differences in prognosis after myocardial infarction: changes from 1978 to 2007.

Women with myocardial infarction (MI) have shown a 28-day survival disadvantage compared with men. However, results were less consistent when considering long-term mortality in 28-day survivors. The aim was to estimate the trends for sex-related differences in the three endpoints considered for this study: (1) 28-day mortality or severe ventricular dysfunction (acute pulmonary oedema or cardiogenic shock) during the hospital stay, (2) 28-day mortality and (3) two-year cardiovascular mortality or non-fatal MI in 28-day survivors after a first MI.

Trends in Q-wave acute myocardial infarction case fatality from 1978 to 2007 and analysis of the effectiveness of different treatments.

Background: We sought to analyze the trends in first Q-wave acute myocardial infarction (AMI) case fatality from 1978 to 2007 in a population-based hospital register, to determine the variables related to these changes, and to assess the effectiveness of current AMI management.

Methods: Population-based hospital registry included patients with first Q-wave AMI aged 25 to 74 years admitted between 1978 and 2007. Sociodemographic and clinical characteristics, treatments, and procedures used during hospital stay, and 28-day case fatality were recorded.

Influence of vine training and sunlight exposure on the 3-alkyl-2-methoxypyrazines content in musts and wines from the Vitis vinifera variety cabernet sauvignon.

The influence of vine training and sunlight exposure on the 3-alkyl-2-methoxypyrazines contents in musts and wines was studied by means of two previously reported methods based on headspace solid-phase micro-extraction. Experimental samples were monitored throughout grape ripening and wine making. 3-Isobutyl-2-methoxypyrazine, 3-sec-butyl-2-methoxypyrazine and 3-isopropyl-2-methoxypyrazine were identified.

Solid-phase microextraction and gas chromatography olfactometry analysis of successively diluted samples. A new approach of the aroma extract dilution analysis applied to the characterization of wine aroma.

The relationship between the composition and the aroma of the wine can be established by using gas chromatography with olfactometric detection (sniffing or GCO), which combines the chromatographic response with the human nose response. To evaluate the contribution of the odor compounds in wine aroma, we designed a new approach of the aroma extract dilution analysis (AEDA) that lies in the GCO analysis of serially diluted wine samples using headspace solid-phase microextraction (HS-SPME) as the extraction technique. The fiber coating used was Flex divinyl-carboxen-polydimethylsiloxane.
