Cada a\u00f1o, unos 500,000 estadounidenses sufren lesiones nerviosas que requieren tratamiento, ya sea por un intento fallido de sacar el hueso de un aguacate o por un desafortunado accidente mientras trabajaban la madera. Muchos nunca recuperar\u00e1n por completo la sensibilidad en los dedos. Sin embargo, una startup<\/em> ha desarrollado un l\u00edquido espeso y pegajoso que podr\u00eda cambiar esta situaci\u00f3n, y ha comenzado a utilizarlo con cirujanos en Estados Unidos.<\/p>\n

La ciencia que supera a la ficci\u00f3n<\/h2>\n

La empresa francesa Tissium est\u00e1 trabajando para sustituir y complementar los puntos de sutura m\u00e9dicos con un l\u00edquido que se adhiere al tejido al exponerse a la luz<\/strong>. Este l\u00edquido, un biopol\u00edmero compuesto por \u00e1cidos grasos y glicerol (ambos presentes de forma natural en el cuerpo), act\u00faa como una f\u00e9rula para mantener los nervios en su sitio mientras el tejido se regenera. Posteriormente, se biodegrada una vez que el cuerpo se ha curado, dejando los nervios intactos.<\/p>\n

Los nervios perif\u00e9ricos conforman la extensa red del sistema nervioso, ramific\u00e1ndose desde el cerebro y la m\u00e9dula espinal hacia el resto del cuerpo. Cuando uno de ellos se secciona (con frecuencia debido a lesiones causadas por cuchillos o maquinaria), es necesario mantener los dos extremos en su sitio mientras el nervio se repara lentamente por s\u00ed mismo. Si no se hace as\u00ed, se sufrir\u00e1n s\u00edntomas que van desde hormigueos y p\u00e9rdida total de sensibilidad hasta un dolor punzante similar a una descarga el\u00e9ctrica.<\/p>\n

Alinear los nervios seccionados requiere microsuturas, lo cual es \u201cuna t\u00e9cnica muy delicada\u201d, asegura Mar\u00eda Pereira, cofundadora y directora ejecutiva adjunta de Tissium, \u201cpor lo que estamos tratando de ofrecer una nueva y mejor forma de preparar los nervios perif\u00e9ricos de manera uniforme, menos traum\u00e1tica y con mejores resultados para los pacientes\u201d.<\/p>\n

Ya est\u00e1 disponible<\/h2>\n

La empresa llev\u00f3 a cabo un ensayo con 12 pacientes en EE UU que presentaban lesiones nerviosas en los dedos. Los 12 recuperaron la capacidad de percibir la temperatura, el dolor, la textura y el tacto ligero en los dedos, frente a poco m\u00e1s del 80%<\/a> con otras t\u00e9cnicas. Ninguno inform\u00f3 de dolor ni de complicaciones relacionadas con el dispositivo un a\u00f1o despu\u00e9s. El tratamiento ya est\u00e1 disponible para que los cirujanos lo adquieran en EE UU.<\/p>\n

\u201cAunque se necesitan m\u00e1s pruebas, es emocionante ver que los cirujanos modernos tienen a su disposici\u00f3n biomateriales y t\u00e9cnicas de medicina regenerativa m\u00e1s avanzados\u201d, asegura Simran Chana, cirujana, cient\u00edfica especializada en materiales y directora del Laboratorio de Tecnolog\u00edas de Vanguardia de la Universidad de Cambridge. Chana no participa en el trabajo de Tissium.<\/p>\n

Tissium ha recaudado 30 millones de euros (m\u00e1s de 34 millones de d\u00f3lares) en inversiones privadas procedentes de empresas de capital de riesgo y family offices<\/em> para ampliar su comercializaci\u00f3n, seg\u00fan ha comunicado la empresa en exclusiva a WIRED, adem\u00e1s de 30 millones de euros en financiaci\u00f3n mediante deuda del brazo crediticio de la Uni\u00f3n Europea, el Banco Europeo de Inversiones. La empresa seguir\u00e1 fabricando su producto, que recibi\u00f3 la autorizaci\u00f3n de comercializaci\u00f3n de la FDA el a\u00f1o pasado, en el norte de Francia.<\/p>\n

Los fondos tambi\u00e9n respaldar\u00e1n el desarrollo de la aplicaci\u00f3n de la tecnolog\u00eda a otras afecciones: Tissium prev\u00e9 reclutar a unos 200 pacientes en un ensayo en EE UU para ayudar al cuerpo a recuperarse tras el tratamiento de una hernia. Los cirujanos tratan las hernias empujando el \u00f3rgano o tejido protuberante de vuelta a trav\u00e9s de la pared muscular y, a continuaci\u00f3n, reforzando la zona con puntos de sutura y malla. Actualmente, \u201cpuede haber cierta inconsistencia en la forma de realizar las suturas, lo que puede afectar a los resultados\u201d, expresa Pereira, que tambi\u00e9n es directora de innovaci\u00f3n de la empresa. A\u00f1ade que el tratamiento de Tissium puede aportar esa consistencia, lo que a su vez puede mejorar el proceso de recuperaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
