Mayo Clinic Q and A: During pregnancy, stick to the basics to ensure good nutrition for baby

By lizatorborg

DEAR MAYO CLINIC: I’m newly pregnant and overwhelmed with food advice from my friends. Is it true that I shouldn’t eat any deli meat during my pregnancy? What about caffeine? Can it harm the baby? Are there other foods I should avoid while pregnant?pregnant woman eating healthy vegetables

ANSWER: The list of foods people think you should and shouldn’t eat while you’re pregnant can quickly become long and confusing. Although there are some specific do’s and don’ts, stick to the basics. Eating a healthy, well-balanced diet that’s low in fat and does not include alcohol is a solid way to ensure good nutrition for you and your baby.

For most people, pregnant women included, healthy eating involves plenty of vegetables, fruits, whole-grain foods and lean protein, as well as some healthy fats such as those found in fish, nuts, seeds and plant-based oils. Nutrients important for women during pregnancy include calcium and vitamin D for strong bones, folate to reduce the risk of birth defects, iron to prevent anemia and protein to help your baby grow. Getting enough fiber and fluids also is important to avoid constipation and to keep you hydrated. Read the rest of this entry »

Estudio de Mayo Clinic sugiere cuáles pacientes con glioblastoma se beneficiarían del tratamiento farmacológico

By Soledad Andrade

JACKSONVILLE, Florida: Los médicos a cargo de las pruebas sobre el fármaco dasatinib, autorizado para varios cánceres de la sangre, esperaban que éste ralentizase el crecimiento agresivo del mortal tumor cerebral  llamado glioblastoma; pero los ensayos clínicos realizados hasta la fecha no han descubierto ningún beneficio. Los científicos de Mayo Clinic a cargo de la realización de uno de esos ensayos clínicos creen saber por qué fracasó el dasatinib, y qué hacer al respecto.

Ilustración de un glioma en un jovenEn la edición electrónica de Molecular Oncology (Oncología molecular), los investigadores informan el descubrimiento de que el dasatinib inhibe a las proteínas que promueven el crecimiento del cáncer, según se anticipaba, pero también suprime a las proteínas que protegen contra el cáncer.

Los hallazgos plantean que primero realizar pruebas en las biopsias de los pacientes con glioblastoma permitiría identificar quiénes responderían bien al dasatinib y cuáles personas deberían evitar el fármaco, explica el autor experto del estudio Dr. Panos Z. Anastasiadis, director del Departamento de Biología Oncológica en Mayo Clinic de Florida.

El dasatinib es un inhibidor general de las quinasas de la familia Src (SFK, por sus siglas en inglés). El fármaco apaga a todos los miembros de la familia Src de las proteínas quinasas, consideradas las responsables de activar proteínas que básicamente proveen “piernas” a los tumores para que se desplacen por el tejido en busca de nutriente sanguíneos.

En el estudio, los investigadores examinaron detalladamente el efecto ejercido por el dasatinib sobre los miembros de la familia Src (Src, Fyn, Yes y Lyn) a través de líneas celulares para glioblastoma del laboratorio y ratones modelo para cáncer de cerebro.

En las líneas celulares, la inhibición de Src, Fyn y Yes generalmente redujo el crecimiento y la migración. En Lyn ocurrió lo mismo, pero en menor grado.

Sin embargo, en los ratones hubo diferencias importantes, dependiendo de cuál miembro de la familia Src se inhibía experimentalmente. Los ratones con glioblastomas sin Src o Fyn funcional no mostraron diferencia en la supervivencia frente a los ratones no tratados. En cambio, la inhibición de Yes en los ratones aumentó la supervivencia, mientras que la inhibición de Lyn derivó en supervivencia más corta y crecimiento acelerado del tumor.

La terapia con rayo de protones produce menos efectos secundarios que la radioterapia estándar

By Soledad Andrade

ESTIMADA MAYO CLINIC:
¿Qué hace la terapia con rayo de protones por los pacientes que no haga la radioterapia estándar? ¿Cómo deciden los médicos cuándo aplicar la terapia con rayo de protones?

Child receiving proton beam therapy: pencil beam scanning radiotherapy

Terapia con rayo de protones: un niño recibe radioterapia con barrido mediante haz del grosor de un lápiz,

RESPUESTA:
La terapia con rayo de protones es un tipo de radioterapia que se emplea en el tratamiento del cáncer. A diferencia de la radioterapia estándar, cuyos rayos X viajan hasta llegar al cuerpo de la persona, los protones van al tumor, descargan la energía y se detienen. Eso significa que la terapia con rayo de protones tiende a ser más eficaz y ocasiona menos efectos secundarios que la radioterapia estándar.

Los protones son partículas subatómicas que se combinan con los neutrones para formar el núcleo del átomo, alrededor del cual orbitan los electrones. La radiación es la energía liberada desde los átomos, sea como ondas electromagnéticas (rayos X o rayos gamma), o como diminutas partículas (electrones o protones). Durante más de 20 años, la radiación ha servido para destruir a las células cancerosas.

Actualmente, la radioterapia estándar utiliza rayos X de alta energía que se desplazan por el cuerpo, pero la terapia con rayo de protones es diferente porque ese tratamiento dirige los protones hacia el tumor, donde liberan su energía. Los oncólogos radioterapeutas pueden ajustar la energía de los protones para controlar cuán profundo penetrarán y dónde liberarán la energía. La regla es que mientras mayor sea la energía, más profundo penetrarán los protones.

La cantidad de energía que se libera a medida que el protón ingresa al cuerpo de una persona es muy baja y la mayor parte se libera en los últimos milímetros del recorrido del protón, lo que significa que la cantidad más grande de radiación se libera directamente dentro del tumor.

By Joel Streed

According to the National Cancer Institute, more than 23,000 new cases of brain cancer were diagnosed in the U.S. last year. Of those, about one-third were gliomas ... a type of brain cancer that's particularly hard to treat. On this week's program, Dr. Robert Jenkins, a pathologist and specialist in laboratory genetics, explains new research that may lead to more effective treatments for gliomas. And scientist Dr. Richard Vile describes how a teenage girl with brain cancer changed the focus of his research. Also on the program, orthopedic surgeon Dr. John Sperling talks about rotator cuff injury ... what it is and how it's repaired. And, the Consumer Product Safety Commission reports that about 240 people go to the emergency room each day during the weeks around the Fourth of July with fireworks-related injuries. Surgeon and trauma specialist Dr. Donald Jenkins discusses the hazards of using fireworks at home.

Mayo Clinic Transplant Programs Rank Among Best in U.S. for Survival Rates

By Lynn Closway

heart transplant surgery with Dr. Daly
PHOENIX — Mayo Clinic, as a three-site organization, remains the largest provider of solid organ transplants in the U.S. and continues to be identified as having patient and graft survival outcomes that rank among the best in the nation.

According to the Scientific Registry of Transplant Recipients (SRTR), a national database of transplant statistics, Mayo Clinic’s transplant programs in Arizona, Florida and Rochester, Minn., score statistically better than expected in terms of patient and graft survivals at the reported time points of one month, one year and three years. Graft survival means that the transplanted organ is still functioning.

The lung transplant program at Mayo Clinic’s Florida campus was one of two lung transplant programs in the U.S. with statistically better-than-expected outcomes for one-year patient and graft survival. Florida’s liver transplant program, with  three-year patient and graft survival rates that also are statistically better than expected, is one of only four programs meeting this criteria at that time point.

Keep Your Summer Safe and Injury Free + SAVING LIVES WITH GUS: Fireworks Safety

By Dana Sparks

U.S. American flag, July 4th, sparklers, fireworks
With the 4th of July holiday week coming up, experts at Mayo Clinic are offering up some injury prevention tips on some of the most common reasons that send people to the emergency department this time of year.

  • Consume alcohol in moderation. Imbibing too much alcohol can lead to questionable decision-making, slowed reflexes and false confidence – traits that are dangerous in nearly any outdoor activity during the summer months.
  • Never assume a campfire or bonfire is completely out. On more than one occasion, fire-happy campers have been known to dump gasoline or other extremely flammable liquids on fires that look like they are out or smoldering and ended up with third-degree burns. Children and adults make trips to the emergency room every summer after stepping into fire pits they thought were cool.
  • Always wear a helmet when biking, motorcycling, horseback riding or on an ATV. This is like wearing a seat belt in a car – an absolute must. Riders of all kinds can sustain serious injuries in an accident, but survival chances grow exponentially when a helmet is worn.
  • Be extra alert when operating a boat or personal watercraft.  Watch out for other boaters, water-skiers and swimmers. Every year, patients are brought to the emergency department after getting tangled up in a boat propeller. And always wear a life jacket.
  • Avoid fireworks. Even sparklers – thought to be relatively safe – can lead to blindness and serious burns. Other larger fireworks can leave users without fingers and even limbs. Hearing loss is common among fireworks users as well. Children must be closely supervised at all times around any kind of fireworks.
