Dr. Max Gomez: Custom Made Knee Replacements

CBS New York

“At present, there’s little that orthopedists can do to regenerate a torn knee meniscus,” said study leader Jeremy Mao, DDS, PhD, the Edwin S. Robinson Professor of Dentistry (in Orthopedic Surgery) at the Medical Center. “Some small tears can be sewn back in place, but larger tears have to be surgically removed. While removal helps reduce pain and swelling, it leaves the knee without the natural shock absorber between the femur and tibia, which greatly increases the risk of arthritis.”

3D-printed implants could let injured athletes play again

New York Daily News

An idea that once seemed absurd is now looking entirely possible, for researchers at Columbia University Medical Center have managed to successfully implant 3D-printed cartilage in sheep. …At present, there is no way to regenerate damaged menisci and in severe cases, they must be removed, which can bring an athlete’s career to an early end for it leaves him without a shock absorber between the femur and tibia, according to study leader Jeremy Mao, DDS, PhD.

Torn knee joint? This 3D-printed implant will help you grow a new one

FOX News

3D-printed prosthetic body parts certainly aren’t anything new at this point, but a team of medical researchers at Columbia University Medical Center has just taken the idea to a whole new level. Instead of replacing a damaged body part with an artificial insert, they’ve cooked up a way to use 3D printing in conjunction with stem cells to encourage your body to regrow the damaged part on its own.

Fractures are major cause of older women’s hospitalizations

“We’ve known for a long time that osteoporotic fractures are the source of a lot of expense and pain,” said Dr. Ethel S. Siris, past president of the National Osteoporosis Foundation and director of the Toni Stabile Osteoporosis Center of the Columbia University Medical Center at New York-Presbyterian Hospital.

Lower IQ found in kids exposed to high chemical levels in utero

Washington Post

Previous research linked higher exposure to chemicals called “phthalates” to poor mental and motor development in preschoolers. This study was said to be the first to report a link between prenatal exposure to the chemicals and childhood development. Researchers from Columbia University’s Mailman School of Public Health studied exposure to five types of phthalates, which are sometimes referred to as “hormone disruptors” or “endocrine disruptors.”

When a Rapist’s Weapon Is a Drug

New York Times

One of those motives is obvious: simple opportunism, the reason men have spiked women’s drinks (or less commonly, women men’s) since the dawn of cocktail hour. Another is coercion; the perpetrator is aroused by domination, forcing his (or rarely, her) sexual will on the target. “This is common enough that we debated whether to include it as a diagnosis in the D.S.M. 5,” psychiatrists’ influential diagnostic manual, said Dr. Michael First, a Columbia psychiatrist who edited it. But the idea was shelved, in part because of concerns that doing so would give rapists added recourse in legal cases, he said.

Post-Newtown momentum on mental health has slowed

USA Today

“When you’ve been through a couple decades of these kinds of cycles, it gets pretty discouraging,” said Paul Appelbaum, a professor of psychiatry, medicine and law at the Columbia University Medical Center in New York, who wasn’t involved in the new report. “As the memory of these tragedies fade, there is a reversion to a state of indifference.”

Stem Cells Hold Promise for Skin Disease Treatment

Wall Street Journal

A third study, led by scientists at Columbia University, focused on certain cells in EB patients that spontaneously revert to a normal state. The scientists showed that it was possible to change those “revertant” cells into pluripotent cells, and then into fresh, healthy skin tissue that secretes the required collagen.

Merck’s Vytorin First Cholesterol Drug to Further Cut Heart Risk

Bloomberg News

The drugs shouldn’t be used broadly to prevent a first heart attack or similar cardiac complication, said Lori Mosca, professor at Columbia University Medical Center and director of preventive cardiology at New York-Presbyterian Hospital. For those who already have a heart disease, the modest benefit seen in the study may be important, she said. “This is a group of people who have suffered,” she said in an interview. “Every attempt to reduce their risk of a recurring problem is appropriate.”

Risk Model Seen as Reducing Military Suicides

“The most impressive thing is that they identified this high-risk group in the hospital, and by just focusing on one in 20 of them, you’re really dramatically improving your ability to predict,” said Dr. Mark Olfson, a professor of psychiatry at Columbia University who was not involved in the study. “Clinicians don’t do a very good job predicting suicide risk, even though we think we do.”

Switzerland Hands Out Iodine in Case of Nuclear Disaster

Bloomberg News

“There’s a concern that this will be seen as a universal panacea to protect you from all types of radiation exposure, which it isn’t,” said David Brenner, professor of radiation biophysics at Columbia, said yesterday by telephone from New York. Children, rather than adults, were at risk of developing thyroid cancer due to radioactive iodine and would therefore be best served by the pills, he said.

Ebola and Quarantine

New England Journal of Medicine

The governors of a number of states, including New York and New Jersey, recently imposed 21-day quarantines on health care workers returning to the United States from regions of the world where they may have cared for patients with Ebola virus disease. We understand their motivation for this policy — to protect the citizens of their states from contracting this often-fatal illness. This approach, however, is not scientifically based, is unfair and unwise, and will impede essential efforts to stop these awful outbreaks of Ebola disease at their source, which is the only satisfactory goal. The governors’ action is like driving a carpet tack with a sledgehammer: it gets the job done but overall is more destructive than beneficial.

To Improve a Memory, Consider Chocolate

New York Times

In a small study in the journal Nature Neuroscience, healthy people, ages 50 to 69, who drank a mixture high in antioxidants called cocoa flavanols for three months performed better on a memory test than people who drank a low-flavanol mixture. On average, the improvement of high-flavanol drinkers meant they performed like people two to three decades younger on the study’s memory task, said Dr. Scott A. Small, a neurologist at Columbia University Medical Center and the study’s senior author. They performed about 25 percent better than the low-flavanol group.

Ebola’s Quarantine Politics: Why Authorities Push Voluntary Isolation

National Geo

Aside from four people who shared an apartment with Duncan in the early days of his illness, the U.S. government has kept all quarantines voluntary. The fact that those four did not fall ill despite their exposure shows that casual contact, such as sharing an airplane, with someone before they are significantly symptomatic carries very little risk, said Amy Fairchild, a professor of sociomedical sciences at Columbia University’s Mailman School of Public Health in New York City.

How to Quarantine Against Ebola

New York Times

There is a fourth strategy, although it will need to be evaluated and deployed carefully. Since the 1990s, novel methods have allowed doctors to detect viruses in the pre-symptomatic phase of an infection, often with remarkable sensitivity and precision. One of these involves the polymerase chain reaction, or P.C.R., a chemical reaction that amplifies pieces of a virus’s genes floating in blood by more than a millionfold, which is what makes early, pre-symptomatic infections identifiable.
