NYU medical experts analyze subway injuries

01.02.2006


A new survey of subway injuries provides a rare glimpse into what happens to people who are hit by oncoming trains. In New York City, where the Metropolitan Transportation Authority reports that 7 million passengers ride the transit system daily, there is no publicly available record of such tragedies. NYU School of Medicine trauma specialists, who conducted the survey at Bellevue Hospital Center, explored who is most at risk for severe subway injuries, why accidents occur, and which preventative measures could be most effective.



"The majority of patients had more minor injuries, like bruises or scratches, or they lost a finger or a toe," says Amber A. Guth, M.D., Associate Professor of Surgery at NYU and primary author of the survey, published in the March 2006 issue of the American Journal of Public Health. During the study, she served as Surgical Director of Bellevue’s Intensive Care Unit. "About half the patients went home right away," she says. Among the minority who lost arms or legs, the limbs were either severed by the train itself or were so mangled that they could not be repaired by a team of vascular surgeons, neurosurgeons, and plastic surgeons.

Because of their expertise in dealing with trauma and in performing microvascular surgery on severed limbs, Bellevue sees the majority of subway accident patients in New York City. Last year, the hospital was chosen by the New York City Health and Hospitals Corporation (HHC) to be the official referral center for all the city’s subway injuries.


Dr. Guth and her colleagues reviewed the cases of 208 patients treated at Bellevue from 1990 to 2003. Their average age was just under 39, though they ranged from five to 93 years old. Approximately 80 percent of the patients were male. The vast majority, 164 patients, did not lose any extremities during the accident. Among the others, injuries varied from the loss of a single finger, for six patients, to the irreparable damage of an arm or leg, for 28 patients. One person lost all four limbs. At the end of their stay, 111 people returned home, while 73 were discharged to a physical rehabilitation center or psychiatric facility. Twenty patients died in the hospital.

During the years of 2000 to 2003, 25 of 56 patients treated were unemployed, and one quarter of injuries were the result of suicide attempts.

"Our goal was really to see if we saw a pattern to the injuries," says Dr. Guth. "We were curious to see if they related to any societal changes, because people who are injured very often are very marginal people, with less economic resources and a lot of psychiatric issues."

When the results were paired with unemployment and homelessness rates, a pattern emerges. At times when the economy weakened, subway injuries did appear to increase, a trend that could be helpful in prevention efforts. "How can we identify groups that are at higher risk? How can we target these people? When you put your resources towards something, it needs to be useful," Dr. Guth explains.

One answer, says Dr. Guth, is surprisingly simple--slow down. If trains enter the station at reduced speeds, motormen would have more time to notice people on the tracks and stop before impact. Any injuries that did happen would be far less severe. In some newer subway systems, such as in Hong Kong, platforms are being built with barriers between passengers and the tracks. But in New York City, where the subway is over a century old, such changes would be prohibitively expensive, Dr. Guth explains. The article also suggests that, during dips in the economy, law enforcement officers and subway staff should be especially alert to people whose behavior suggests they are considering a suicide attempt.

The authors of the new study are: Amber A. Guth, M.D., Andrea O’Neill, R.N., Thomas Diflo, M.D., and H. Leon Pachter, M.D. of NYU School of Medicine.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
