We all know that it is easier to learn a new language or musical instrument as a child rather than in adulthood. At no other time in life does the surrounding environment so potently shape brain function – from basic motor skills and sensation to higher cognitive processes like language – than it does during childhood. This experience-dependent process occurs at distinct time windows called “critical periods”, which are times of great opportunity but also of great vulnerability for the developing brain. Early disruption of proper sensory or social experiences will result in mis-wired circuits that will respond sub-optimally to normal experiences in the future. Comparable effects are also seen for the development of vision, where if a child’s binocular vision is compromised and not corrected before the age of eight, amblyopia (‘lazy eye’) is permanent and irreversible.
A growing body of evidence suggests that the use of marijuana, or cannabis, can negatively impact the developing brains of approximately one in four adolescents, according to researchers at Icahn School of Medicine at Mount Sinai, and the University of Montreal.
The study, published in the August 16, 2013, issue of Neuropharmacology, highlights that the younger the user of cannabis, the more susceptible he or she is to delinquency, lower educational attainment, difficulty in conforming to an adult role, and mental health issues.
Every year, more than 1 million Americans develop liver damage caused by prescription and over-the-counter drugs, and dietary and herbal supplements. The condition, known as drug-induced liver injury (DILI), can result in severe liver disease that requires transplantation. There are no tests to predict who is at risk, or to help physicians make an early diagnosis, which would prevent progressive liver damage.
For most of us the word brain is synonymous with nerve cells or neurons. All of us are well familiar with the notion of the brain as a mega-computer where billions of neurons govern our life, from simplest tasks to the rare moments of discoveries. It may appear surprising to hear that the function of brain and neurons would not be possible without cells that do not participate in our thinking directly. Instead, these cells, that are called microglia, function as watchdogs of neuron’s functionality and health and remove neurons that stop acting properly.
Music is Medicine is a nonprofit run by a team of college students that pairs artists with pediatric patients through uplifting music programs. Through Music is Medicine’s Donate a Song project, artists write and record original songs for seriously-ill children to inspire the patients, share their stories of strength, and contribute to the greater fight against their diseases.
This past summer, Cindy, a 16 year-old girl battling cancer at the Mount Sinai Kravis Children’s Hospital, met artists Sam Tsui and Elle Winter. The artists then went on to produce an original song called “Unsinkable” for Cindy. In the chorus Sam and Elle sing, “My heart’s unsinkable. Never doubt that things will get better. Can you feel the love? I’m never giving up.” Through the song, Sam and Elle motivate Cindy and people everywhere to never give up. At the same time, all proceeds for the song will benefit pediatric oncology research at Mount Sinai.
What is the future of stem cell research? Embryonic cells were once so controversial that President George W. Bush limited federal funding in 2001 (a policy that was overturned by President Obama in 2009). Now there is a new type of stem cell, similar to embryonic stem cells, called induced pluripotent stem cells. We’ve all heard the claims concerning the extraordinary potential of stem cells (be they embryonic or induced) in the treatment of human disease. What will be the first commonly used stem cell therapy?
Ovarian cancer is a heterogeneous and rapidly progressive disease of low prevalence and poor survival. In the United States the number of deaths attributed to ovarian cancer approximates that of all other gynecologic malignancies combined. Unfortunately, the majority (75%) of women diagnosed with ovarian carcinoma continue to have advanced stage disease (Stage III/ IV), with widespread metastases throughout the peritoneal cavity, lymph nodes, liver or lungs. Presently less than 20% of women with ovarian cancers are detected when the cancer is still confined to the ovary (Stage I).
Glioblastoma (GBM) is the most common and most aggressive brain tumor, known to be a highly invasive and rapidly spreading disease. Even with aggressive treatment such as surgery, radiation, and chemotherapy, they are almost always incurable.
The Mount Sinai Comprehensive Brain Tumor Program is pioneering the use of electrical tumor treating fields to be used with conventional therapy. The device, manufactured by Novocure, is called NovoTTF and it is FDA approved for recurrent GBM. It consists of a head cap that produces changes in electrical fields, which is worn continuously.
Today’s standard therapies for cancer exist because people have participated in clinical trials – yet choosing to participate in a cancer clinical trial is an important personal decision that can be intimidating for many patients. In order to better help patients understand cancer clinical trials, the reasons to participate in them, and clinical research at Mount Sinai, The Tisch Cancer Institute has released a new video, “Clinical Trials at Mount Sinai: Moving the Field Forward.”
Multiple Sclerosis is an inflammatory demyelinating disorder of the Central Nervous System of debated etiology. While there is general consensus regarding the role of an active immune system in myelin destruction, the questions related to the initial events triggering immune system involvement remain unanswered and the identity of disease course modifiers is only partially understood. Epidemiological studies have suggested the possibility that disease onset and course are the result of an interaction between genetic susceptibility and environmental factors, though much remains to be learned about the identity of the environmental factors and whether they can be modified. Among the proposed variables affecting MS are geographic location, smoking, vitamin D levels and the much debated diet and infections.
