Discovering the volatilome fingerprint of selected traditional Cuban wines elaborated with native grapes, tropical fruits, and rice using DHS-TD-GC-MS.

Cuban wine is a traditional alcoholic beverage elaborated with a wide variety of raw materials, such as native grapes, tropical fruits, and rice, and different winemaking processes. Research on Cuban wines is almost nonexistent, and therefore, a study of these wines is necessary to improve their quality. Dynamic headspace (DHS)-TD-gas chromatography-mass spectrometry (GC-MS) analysis was carried out to establish the different aroma fingerprints of different Cuban wines. A total of 42 volatile aroma metabolites (VAMs) were identified, including esters, alcohols, aldehydes, acids, volatile phenols, terpenes, and lactones. The odorant activity values (OAV) of each VAM were obtained, and the esters were the most relevant group due to their highest OAV. Ethyl octanoate, hexanoate, and butanoate stand out and are considered key odorants in the aromatic fingerprint. The VAMs were grouped into seven aromatic series. Fruity series showed the highest OAVs due to the contribution of ethyl esters and acetates. Principal component analysis was used to identify the specific parameters most accurately reflecting the differences between the wines. Showing that fruity, spicy, and chemical aromatic series allow distinguishing the wines into three aroma types. These results may provide useful information for the selection of raw materials and optimization of the traditional winemaking processes of Cuban wines. PRACTICAL APPLICATION: This research contributes to knowledge of the aroma and the oenological parameters of traditional and selected Cuban wines (rice wine, tropical fruit wine, and native grape varieties). The establishing of the aroma fingerprint of these wines provides useful information for the industrial development of a quality product that may then be promoted in other areas of the world.

Comparison of physicochemical properties, amino acids, mineral elements, total phenolic compounds, and antioxidant capacity of Cuban fruit and rice wines.

Physicochemical characterization, amino acids contents, minerals composition, total phenolic compounds, and antioxidant capacity of Cuban wines from different raw materials were studied. The wines studied were grape wines, tropical fruit wines, and rice wines. Twenty-one amino acids were identified and quantified, being Asp and Glu detected in all wines. The highest concentration of total amino acid content was found in wines elaborated from Cimarrona grape subjected to maceration with grape skins, while the raisined mixture grape wine presented the lowest values, probably caused by the amino acid degradation during the dehydration process by sun exposure. Minerals quantified were range amount limits of acceptable according to the OIV recommendation. Total phenolic compounds and antioxidant capacity showed the greatest values in wine from roasting rice. No statistical separation could be clearly observed by multivariate principal component analysis; however, 3 wine groups could be defined taking account the scores on the PC1.

Respuesta del sistema municipal de salud al huracán Irma. Aguada de Pasajeros, 2017 / Response of the Municipal Health System to Irma Hurricane. Aguada de Pasajeros, 2017

Fundamento: en la respuesta del sistema de salud ante un huracán, los municipios y sus establecimientos tienen un papel protagónico.Objetivo: describir la respuesta del sistema municipal de salud del municipio de Aguada de Pasajeros ante el paso del huracán Irma por el territorio. Métodos: estudio prospectivo, transversal, en sistema y servicios de salud, desarrollado en el municipio de Aguada de Pasajeros entre el 7 y 30 de septiembre de 2017. El universo lo constituyó la totalidad de trabajadores e instituciones del territorio, todos involucrados en la respuesta al huracán Irma. Se incluyeron la revisión documental (planes, indicaciones de los Consejos de Defensa y del Ministerio de Salud) y la observación participativa. También se revisaron indicadores de posible impacto y del cuadro de salud municipal. Resultados: se planificaron y ejecutaron un total de 88 acciones por el sistema municipal de salud; 50 durante la fase informativa, 29 en la de alarma y nueve en la de alerta. El plan de reducción de desastres fue cumplido en su totalidad, al que se le agregaron ocho nuevas tareas como parte de las lecciones aprendidas. No hubo fallecidos atribuidos al huracán, ni cambios en la morbilidad posterior al evento. Existió cobertura asistencial mantenida en sitios de difícil acceso y albergues. Todas las instituciones mantuvieron su vitalidad. Conclusiones: las acciones desarrolladas en el municipio permitieron mantener el cuadro de salud, la atención integral a las personas que demandaron asistencia médica durante el paso del fenómeno natural, así como la vitalidad de las instituciones.

Foundation: in response of the health system before a hurricane, municipalities and establishments have a protagonist role. Objective: to describe the Aguada de Pasajeros municipal health system at the Irma hurricane's path across its territory. Methods: prospective cross study, in the health and service system, developed in the Aguada de Pasajeros Municipality between September the 7th and 30th, 2017. The universe was the territory total of workers and institutions, all involved in the response to Irma's hurricane. A documentary review was included (plans, instructions from the Defense Councils, and the Minister of Health) and participating observation. Indicators of possible impact and municipal health situation. Results: a total of 88 actions by the municipal health system; 50 during the informative phase and 9 in alert. The plan for disaster reduction was totaly achieved, to which 9 new tasks were added. There were no deaths due to the hurricane nor morbidity after the event. There was maintained assistance coverage in sites of difficult access and shelters. All the institutions maintained vitality. Conclusion: the actions developed in the municipality allowed maintaining the health situation, the comprehensive care to the people who demanded medical services during the path of the natural phenomena across the territory institutional vitality.
