Similar punishments for adult, child homicide

AppId is over the quota
AppId is over the quota

NEW YORK (Reuters Health) - People suspected of child abuse homicide are just as likely to get convicted, and have similar sentences, as those who are arrested for killing an adult, according to a new study from Utah.

There have been questions about how courts rule on cases involving violence against children compared to violence against adults, with some studies suggesting that suspects of child abuse aren't as likely to be found guilty or aren't penalized as severely. But that was not the case here, say the authors.

"The most important thing we can do is prevent child abuse... and in the end prevent this from ever happening," said Dr. Hilary Hewes from the University of Utah, who worked on the study.

Still, "I thought it was very reassuring that we value children's lives and we take it seriously when they're lost," she told Reuters Health.

Child abuse homicide is defined as a guardian acting or failing to act in a way that results in a child's death, but doesn't count as aggravated murder. In this study, the definition included abusive head and stomach trauma, as well as asphyxiation and burning.

Using a statewide database of violent crimes, Hewes and her colleagues found 334 cases of adult and child non-justifiable homicide between 2002 and 2007.

That included a total of 66 child homicides, 34 of which were categorized as child abuse homicide, were under Utah's jurisdiction and had suspects that were alive to be prosecuted. Out of all adult crimes, 135 suspects were identified.

Both adult and child offenders were convicted at a similar rate -- 83 percent and 88 percent, respectively. In addition, both groups of suspects were just as likely to receive the highest types of conviction, a capital crime or felony 1, or to get a sentence that included the possibility of life in prison.

The researchers wrote in the Archives of Pediatrics and Adolescent Medicine that the results may not apply to other states, especially places where more youth deaths happen as a result of gang violence, or where medical examiners aren't as thorough about determining cause of death in childhood victims.

But for child abuse crimes in particular, the similar rates of conviction and severity of sentencing show that courts were not being easier on suspects in child cases, despite some beliefs that those crimes "lack intentionality" compared to people who kill adults.

"I think there is a different perception between crimes against children versus crimes against adults because of the huge age difference between the victims," said Wendy Walsh, from the Crimes Against Children Research Center at the University of New Hampshire, who wasn't involved in the new study.

Walsh was part of a study that found that in the 1980s and 1990s, child abuse cases were less likely to lead to charges being filed once they went to the prosecutor.

But in this case, she told Reuters Health, "I'm not surprised they did find these similar results, given the extremely aggressive, violent nature of these crimes."

HEALTH MANAGEMENT. Adult stem cells used to grow cervical vertebrae

Neurosurgery researchers at UC Davis Health System have used a new, leading-edge stem cell therapy to promote the growth of bone tissue following the removal of cervical discs -- the cushions between the bones in the neck -- to relieve chronic, debilitating pain.
The procedure was performed by associate professors of neurosurgery Kee Kim and Rudolph Schrot. It used bone marrow-derived adult stem cells to promote the growth of the bone tissue essential for spinal fusion following surgery, as part of a nationwide, multicenter clinical trial of the therapy.
Removal of the cervical disc relieves pain by eliminating friction between the vertebrae and/or nerve compression. Spinal fusion is used following surgery for degenerative disc disease, where the cushioning cartilage has worn away, leaving bone to rub against bone and herniated discs, where the discs pinch or compress nerves.
"We hope that this investigational procedure eventually will help those who undergo spinal fusion in the back as well as in the neck," said Kim, who also is chief of spinal neurosurgery at UC Davis. "And the knowledge gained about stem cells also will be applied in the near future to treat without surgery those suffering from back pain."
Millions of Americans are affected by spine diseases, with approximately 40 percent of all spinal fusion surgery performed for cervical spinal fusion. Some 230,000 patients are candidates for spinal fusion, with the numbers of potential patients increasing by 2 to 3 percent each year as the nation's population ages.
"This is an exciting clinical trial to test the ability of the bone-forming stem cells from healthy donors to help patients with spinal disease," said Jan Nolta, director of the UC Davis Institute for Regenerative Cures.
"For the past 50 years, bone marrow-derived stem cells have been used to rebuild patients' blood-forming systems. We know that subsets of stem cells from the marrow also can robustly build bone. Their use now to promote vertebral fusion is a new and extremely promising area of clinical study," she said.
The stem cell procedure at UC Davis took place early in August. The patient was a 53-year-old male from the Sacramento region with degenerative disc disease.
In the surgery, called an anterior cervical discectomy, a cervical disc or multiple discs are removed via an incision in the front of the neck. The investigational stem cell therapy then is applied to promote fusion of the vertebrae across the space created by the disc removal.
The stem cells are derived from a healthy single adult donor's bone marrow, and thus are very homogenous, Kim said. They are grown in culture to high concentration with minimal chance for rejection by the recipient, he said.
Adequate spinal fusion fails to occur in 8 to 35 percent or more of patients, and persistent pain occurs in up to 60 percent of patients with fusion failure, which often necessitates additional surgery.
"A lack of effective new bone growth after spine fusion surgery can be a significant problem, especially in surgeries involving multiple spinal segments," said Schrot, co-principal investigator for the study. "This new technology may help patients grow new bone, and it avoids harvesting a bone graft from the patient's own hip or using bone from a deceased donor."
Current methods of promoting spinal fusion include implanting bone tissue from the patient's hip or a cadaver to encourage bone regrowth as well as implanting bone growth-inducing proteins. However, the Food and Drug Administration has not approved the use of bone morphogenetic proteins for cervical spinal fusion. Their use has been associated with life-threatening complications, particularly in the neck.
The leading-edge stem cell procedure is part of a prospective, randomized, single-blinded controlled study to evaluate the safety and preliminary efficacy of an investigational therapy: modified bone marrow-derived stem cells combined with the use of a delivery device as an alternative to promote and maintain spinal fusion.
The study includes 10 investigational centers nationwide. The UC Davis Department of Neurological Surgery anticipates enrolling up to 10 study participants who will be treated with the stem cell therapy and followed for 36 months after their surgeries. A total of 24 participants will be enrolled nationwide.
The study is one of several clinical trials under way in the UC Davis Spine Center and led by Kim. He anticipates launching a clinical trial soon to study the safety of injecting stem cells into disc tissue to repair degenerated discs.
The current study is sponsored by Mesoblast, Ltd., of Melbourne, Australia, which is developing adult universal-donor stem cell products built upon the discovery of adult-derived mesenchymal precursor cells. Kim and Schrot will not be compensated for their participation in the study.
