1. To stent or not?
A large randomized trial demonstrates that stenting and surgical clearing of arteries are safe and equally effective ways of treating the narrowing of the carotid arteries, called stenosis.
T.G. Brott et al., N Engl J Med, 363:11-23, 2010. Evaluated by G. Tang and J. Matsumura, University of Wisconsin; M. Alberts, Northwestern University, M. Nishikawa and T. Milhorat, North Shore University Hospital; P. Pagel & C. J. Zablocki, VA Medical Center; P. Newfield, California Pacific Medical Center; B. Norrving, Lund University Hosp; S. Kumar & S. Bangalore, Brigham & Women's Hospital; Z. Anastasian & E. Heyer, Columbia University; N. Hertzer, The Cleveland Clinic. Free F1000 Evaluation

2. Drug helps - not hurts - in serious lung disease
Doctors have hesitated to give neuromuscular blocking agents to patients with the life-threatening lung condition called acute respiratory distress syndrome, out of fear the drugs could cause muscle weakness. But a clinical trial found patients who took a neuromuscular blocker were more likely than those on a placebo to survive 90 days, and showed no increase in muscle weakness. (Some faculty members, however, disagreed with the paper's conclusions, arguing narcotics are more appropriate in these patients.)
L. Papazian et al, N Engl J Med, 363:1107-16, 2010. Evaluated by M. Gropper, University of California, San Francisco; R. Basner, Columbia University College of Physicians and Surgeons; J. Sellares and A. Torres, Hospital Clinic de Barcelona; M. Gama de Abreu, Clinic Carl Gustav Carus; J. Neely & A. Vuylsteke, Papworth Hospital; G. Martin, Emory University; M. O'Connor, University of Chicago; P. Fassbender & M. Eikermann, Massachusetts General Hospital. Free F1000 Evaluation

3. Early palliative care helps in advanced cancer
Patients with inoperable, metastatic non-small-cell lung cancer may benefit from early palliative care, reporting a better quality of life, and less depression than those who did not receive palliative care. Median survival also improved in those receiving early palliative care, even though they were less likely to receive aggressive treatment at the end of their lives.
J.S. Temel et al, N Engl J Med, 363:733-42, 2010. Evaluated by F. Ajaz and R. ZuWallack, St Francis Hospital; D. Spiegel, Stanford University School of Medicine; P. Lee, National University Hospital, Singapore; M. Rodin, St. Louis University Medical School; N. Chao, Duke University Medical Center; H. Klepin, Wake Forest University School of Medicine.

4. Key element of bone marrow stem cell niche spotted
Researchers have struggled to characterize the cellular components of the hematopoietic stem cell niche in bone marrow, but one has been newly pegged: the other bone marrow stem cell (mesenchymal stem cell), capable of differentiating into cartilage- and bone-forming cells, appears to organize and regulate the stem cell niche in bone marrow, the authors note.
S. Mendez-Ferrer, Nature, 466:829-34, 2010. Evaluated by Y. Pang & T. Cheng, University of Pittsburgh; N. Bazhanov & D. Prockop, Texas A&M Health Sciences Center; M. Riminucci & P. Bianco, University of Rome "La Sapienza"; Y. Matsumoto and T. Suda, Keio University. Free F1000 Evaluation

5. Genes behind patchy hair loss
A genome-wide association study provides clues to the mysterious pathogenesis of alopecia areata (AA), a common autoimmune disease in which hair falls out in patches, affecting an estimated 2 percent of the population. The paper reveals more than 100 SNPs associated with AA, involved in both innate and adaptive immunity.
L. Petukhova et al, Nature, 466:113-7, 2010. Evaluated by S. Inui & S. Itami, Osaka University; Y. Ramot & A. Zlotogorski, Hadassah-Hebrew University Medical Center; R. Sinclair, University of Melbourne. Free F1000 Evaluation

6. Don't wake me, please
The brain doesn't passively transition between consciousness and unconsciousness during anesthesia, based simply on how much of the drug is present, as previously thought, a new study in mice and Drosophila reports. These findings suggest the brain has a tendency to resist such transitions, and may provide insights in sleep regulation and disorders.
E.B. Friedman et al, PLoS One, 5(7):e11903, 2010. Evaluated by M. Perouansky, University of Wisconsin; E. Whitlock & M. Avidan, Washington University; M. Sahinovic & A. Absalom, University Medical Center Groningen. Free F1000 Evaluation

7. Pain relief for the addicted
In patients with a dependence on opiates, pain relief is tough to achieve, but those who received ketamine, an N-methyl-d-aspartate receptor antagonist, with anesthesia during back surgery reported less pain and needed less morphine during recovery.
R.W. Loftus, et al, Anesthesiology, 113:639-46, 2010. Evaluated by C. Rivat & P. Richebe, University of Washington; L. Le-Wendling & A. Boezaart, University of Florida College of Medicine; A. Barreveld & D. Correll, Brigham & Women's Hospital; A. Lynn, Children's Hospital, Seattle; D. Gupta, Feinberg School of Medicine Northwestern University. Free F1000 Evaluation
