Dance as a neurorehabilitation strategy: A systematic review.

OBJECTIVE: This systematic review aimed to demonstrate the benefits of dance-based therapeutic interventions in rehabilitation processes in patients with neurological disorders. METHODS: Searches on the following databases and electronic search engines were conducted: MEDLINE, LILACS, Science Direct, SCOPUS, PeDro, BVS (virtual health library), and Google Scholar. Data extraction was independently performed by two authors. Twenty-five clinical trial-type studies that included dance and established outcome measures were included, and studies in which a musicalized exercise modality was used without the connotation of dance were excluded. RESULTS: From the results of multiple studies, the short-term motor benefits of rhythmic auditory stimulation on gait parameters were highlighted. Furthermore, there was scientific evidence demonstrating the benefits of the cognitive and social parameters of group dancing as significant improvements in cognitive flexibility and processing speed were highlighted. Recent studies showed that interventions based on exercise and/or rhythmic choreography can reduce the risk of falls in patients with neurological disorders, thereby improving their quality of life. CONCLUSION: These findings suggest that dance is an innovative and effective method that can be included in therapies as it allows for a promising prognosis in motor, cognitive, and social performances of patients with neurological disorders that alter mobility and quality of life.

Características de la infección por Clostridium difficile en una institución de alta complejidad y reporte de la circulación en Colombia de la cepa hipervirulenta NAP1/027 / Characteristics of Clostridium difficile infection in a high complexity hospital and report of the circulation of the NAP1/027 hypervirulent strain in Colombia

Resumen Introducción. Clostridium difficile es el principal responsable de la diarrea asociada al uso de antibióticos. En Colombia y en Latinoamérica, el conocimiento sobre el comportamiento epidemiológico de la infección por C. difficile todavía es limitado. Objetivo. Describir las características de una serie de pacientes con infección por C.difficile . Materiales y métodos. Se hizo un estudio descriptivo de una serie de casos de pacientes con infección por C. difficile atendidos en la Fundación Clínica Shaio, entre enero de 2012 y noviembre de 2015. Resultados. Se estudiaron 36 pacientes con una edad promedio de 65 años. Se determinaron los siguientes factores relacionados con la infección por C. difficile: uso previo de antimicrobianos (94,4 %), hospitalización en los últimos tres meses (66,7 %) y uso de inhibidores de la bomba de protones (50 %). Las comorbilidades más comunes fueron la enfermedad renal crónica (41,7 %) y la diabetes mellitus (30,6 %). Los síntomas más frecuentes fueron más de tres deposiciones diarreicas (97,1 %) y dolor abdominal (42,9 %). En cuanto a la gravedad de los casos, 44,4 % se clasificó como leve a moderado, 38,9 % como grave, y 11,1 % como complicado o grave. El método de diagnóstico más utilizado (63,8% de los pacientes) fue la identificación de la toxina mediante reacción en cadena de la polimerasa (PCR). La mortalidad global durante la hospitalización fue de 8 %. Se identificaron cuatro cepas del serotipo NAP1/027 y nueve muestras fueron positivas para la toxina binaria. Conclusión. La infección por C. difficile debe sospecharse en pacientes con deposiciones diarreicas y factores asociados tradicionalmente a esta enfermedad. Se reportó la circulación de cepas hipervirulentas del serotipo NAP1/027 en Colombia, lo cual debe enfrentarse con la vigilancia epidemiológica y el diagnóstico temprano.

Abstract Introduction: Clostridium difficile is the main pathogen related to healthcare-associated diarrhea and it is the cause of 20 to 30% of diarrhea cases caused by antibiotics. In Colombia and Latin America, the knowledge about the epidemiological behavior of this infection is limited. Objective: To describe the characteristics of a series of patients with C. difficile infection. Materials and methods: We performed a descriptive case series study of patients with C. difficile infection hospitalized in the Fundación Clínica Shaio from January, 2012, to November, 2015. Results: We analyzed 36 patients. The average age was 65 years. The risk factors associated with the infection were: previous use of antibiotics (94.4%), prior hospitalization in the last three months (66.7%) and use of proton pump inhibitors (50%). The most common comorbidities were chronic kidney disease (41.7%) and diabetes mellitus (30.6%). The most frequent symptoms were more than three loose stools per day (97.1%) and abdominal pain (42.9%). According to the severity of the disease, 44.4% of cases were classified as mild to moderate, 38.9% as severe, and 11.1% as complicated or severe. The detection of the toxin by PCR (GeneXpert) was the most common diagnostic procedure (63.8%). Global mortality during hospitalization was 8%. We identified four strains with serotype NAP1/027 and nine samples positive for binary toxin. Conclusion: Clostridium difficile infection should be suspected in patients with diarrhea and traditional risk factors associated with this disease. We report the circulation of the hypervirulent strain serotype NAP1/027 in Colombia, which should be countered with epidemiological surveillance and a prompt diagnosis.

Green extraction of antioxidants from different varieties of red grape pomace.

The extraction yield, phenolic content, anthocyanin content and antioxidant activity of extracts from different varieties of red grapes, Cabernet Sauvignon, Merlot, Petit Verdot, Syrah, Tempranillo and Tintilla, using pressurized green solvents have been analyzed. Two techniques were studied and compared: supercritical fluid extraction (SFE) with CO2 + 20% ethanol and pressurized liquid extraction (PLE) with either ethanol, water or an ethanol/water mixture as the extraction solvents. The Petit Verdot variety allowed the highest global and phenolic yield, and antioxidant activity. The best conditios for PLE obtained from the experimental design and kinetic study were 50% ethanol/water as the pressurized solvent at 90 bar, 120 °C, a flow rate of 5 g/min and, an extraction time of 90 min. A statistical analysis of variance has been performed and it was found that temperature is the only variable that has a statistical influence on the extraction yield. The antioxidant activity levels of the extracts are very promising and they are similar to those obtained with the antioxidant tocopherol.
