Administration of nitric oxide gas during and for 24 hours following heart surgery decreased the risk of patients developing acute and chronic kidney problems, a randomized, controlled trial conducted in China found.
The first comprehensive study comparing the outcomes of robotic surgery to those of traditional open surgery in any organ has found that the surgeries are equally effective in treating bladder cancer.
A surprising form of cell-to-cell communication in glioblastoma promotes global changes in recipient cells, including aggressiveness, motility, and resistance to radiation or chemotherapy. Paradoxically, the sending cells in this signaling are glioblastoma cells undergoing programmed cell death. The apoptotic cancer cells release extracellular vesicles. These vesicle, or exosomes, carry components that alter RNA splicing in the recipient glioblastoma cells, and this altered splicing promotes therapy resistance and aggressive migration.
The majority of existing simulation studies show that the parts of the brain with high connectivity, the so-called 'hubs', are most important when it comes to several different cognitive tasks. But the results of a rare in-vivo study by Gino Del Ferraro of The City College of New York recently published in Nature demonstrates that the nucleus accumbens (NAc) -- a part of the brain with weak connections -- plays an unexpectedly influential role in enhancing the memory network.
In a new study, researchers from Brigham and Women's Hospital evaluated patient-reported satisfaction and well-being outcomes prior to, and two years after their initial surgery for more than 2,000 women across the United States. Researchers found that patients who underwent autologous reconstruction had greater satisfaction with their breasts, as well as a greater psychosocial and sexual well-being two years after surgery, than did those who underwent implant reconstruction.
The majority of people with severe obesity have a lonely and prolonged struggle with their weight. In one study spanning more than 10 years, 83 percent report that they constantly strive to lose weight or prevent weight gain.
Implementing a nutrition care program for malnourished surgical patients showed a nearly 50 percent reduction in readmission rates, according to new data from Advocate Health Care and Abbott. New guidelines call for hospital reform on improving nutrition before and after surgery for better patient outcomes.
Two studies, a commentary and podcast focus on patient outcomes after breast reconstruction surgery following mastectomy. One studied compared satisfaction and quality of life between patients who had breast reconstruction using implants or their own tissue, and a second study compared two-year complication rates across common breast reconstruction techniques.
A HKU Mechanical Engineering team led by Dr. Kwok Ka-wai recently designed the first neurosurgical robotic system capable of performing bilateral stereotactic neurosurgery inside a magnetic resonance imaging ('MRI') scanner. The team also conducted pre-clinical validation of the system with CUHK neurosurgeons, Dr Danny Chan Tat-ming and Professor Poon Wai-sang. This innovative technological breakthrough can facilitate the treatment of Parkinson's disease and other neuropsychiatric disorders.
Researchers investigated risk factors for the development of opioid dependence in patients undergoing surgery for degenerative spondylolisthesis (DS). They found that, overall, patients were more likely to have a dependency on opioid medications before surgery than afterward.
