El consumo de insectos es una práctica común alrededor del mundo, aunque restringida por cuestiones de cultura o apariencia. No obstante que los insectos tienen un contenido nutrimental importante, ...sus compuestos nutracéuticos son un importante componente de éstos, lo cual puede considerarse en la fabricación de productos alimenticios. La grilleta Pterophylla beltrani Bolivar y Bolivar (Orthoptera: Tettigoniidae) molida como suplemento para aportar antioxidantes a tortillas de maíz, usando diferentes mezclas de harina de maíz y harina de insecto. Tortillas hechas de estas mezclas se sometieron a extracciones en dos tipos de solventes y se cuantificó la presencia de compuestos fenólicos totales, antioxidantes contra el radical DPPH y el radical ABTS. La mayor parte de los compuestos fenólicos y antioxidantes fueron más solubles en agua que en etanol. Esto es un indicativo de su polaridad y la disponibilidad durante el proceso digestivo. Los compuestos antioxidantes no tuvieron efecto sobre la germinación y crecimiento de dos especies de hongos inoculados en tortillas suplementadas. Los compuestos detectados fueron resistentes al proceso de cocción, lo cual asegura que el uso de este insecto aporta un contenido importante a la tortilla de maíz.
BackgroundHaemoptysis is a rare symptom associated with endocarditis. We describe the unusual clinical manifestation of endocarditis on regurgitant bicuspid aortic valve and (probably) secondarily on ...a perimembranous ventricular septal defect (VSD) as massive haemoptysis. Case summaryA 24-year-old male with aortic coarctation, bicuspid aortic valve, and VSD since birth. Previously asymptomatic, he came after an episode of haemoptysis. A computed tomography (CT) scan showed a cavitated lesion in lung. Streptococo viridans was identified in serial blood cultures. Transthoracic echocardiography showed a bicuspid aortic valve with vegetations, suggesting infectious involvement, and severe aortic insufficiency. Transoesophageal echocardiography (TEE) study showed a bicuspid aortic valve with complete fusion of coronary valves. An elongated oscillating tumour, 9.5 mm in length, was observed in the centre of the ventricular side of the non-coronary valve. Another vegetation was seen on the VSD. During his hospital stay and under antibiotic treatment, he reported abdominal pain. Computed tomography examination showed splenic infarction. In the echocardiogram no vegetation masses were observed on the aortic valve or on the VSD closure aneurysm. DiscussionThe main debate about this patient's treatment concerned the indication of surgery, especially after the onset of fever with splenic septic embolism while under appropriate antibiotic treatment. He was stable, with no signs of heart failure and the echocardiogram repeated after the septic splenic embolism showed no residual vegetations on the aortic valve or VSD, and the TEE study ruled out a local complication. Finally, the multidisciplinary team decided against surgical management.
Analizamos los resultados de la reparación valvular mitral en 81 pacientes consecutivos con insuficiencia severa de la válvula. El 66,6% de los pacientes tenía degeneración mixoide; el 11%, etiología ...isquémica; el 8%, rotura de cuerdas; el 5%, congénita y el 3,7%, endocarditis. En 5 casos fue preciso sustituir la válvula al no conseguirse una reparación adecuada. La mortalidad operatoria fue de 6 pacientes (7%). En el seguimiento (media, 30 ± 8 meses) hubo un fallecimiento por insuficiencia cardiaca isquémica refractaria y 11 pacientes quedaron con insuficiencia mitral ≥ 2/4. Se obtuvo buen resultado (supervivencia sin prótesis, regurgitación mitral > 1/4 o complicación mayor) en el 78% de los pacientes con afección mixoide frente al 48% de aquellos cuya enfermedad no era mixoide (p = 0,023). La tasa de buen resultado fue superior en la degeneración aislada del velo posterior que en la afección de ambos velos (85% frente a 70%; p = 0,003).
We analyzed the results of mitral valve repair in 81 consecutive patients with severe mitral regurgitation. Of these patients, 66.6% had myxomatous degeneration, 11% ischemic disease, 8% chordal rupture, 5% congenital disease, and 3.7% endocarditis. Repair could not be achieved in five patients, and valve replacement was necessary. Six died during surgery (mortality 7%). During follow-up (mean 30 8 months), there was one death due to refractory ischemic heart failure and mitral regurgitation (≥ 2/4) was observed in 11 patients. A good result (i.e., survival without a prosthesis, major complications, or mitral regurgitation >1/4) was obtained in 78% of patients with myxomatous degeneration versus 48% of those with other etiologies (
P=.023). A good result was obtained more frequently in cases of isolated posterior cusp degeneration than in those involving degeneration of both cusps (85% vs 70%;
P=.03).
