Washington, DC, USA. General anesthesia puts patients into unconscious sleep so they do not feel surgical pain, but researchers say it can increase their discomfort once they wake up.
The findings provide scientific confirmation for an increasing number of anecdotal observations in clinics.
In the Proceedings of the National Academy of Sciences (PNAS), scientists report that "noxious" anesthesia drugs — which includes most of these general anesthetics - activate and ... |

Edmunton, Alberta, Canada. Does emotional wisdom come with age? Researchers identified brain patterns that help healthy people over the age of 60 regulate and control emotion better than younger counterparts. Two brain regions increased activity when participants viewed standardized pictures of emotionally challenging situations.
Dr. Florin Dolcos, University of Alberta (U of A), conducted the study in collaboration with researchers from Duke University. Dolcos is a member of ... |

 | Springfield, VA, USA. The American Psychiatric Association (APA) publishes the Manual for Diagnosis of Mental Disorders (DSM-IV) in 1994.
DSM-IV is the desktop reference used most often by physicians and other caregivers for diagnostics, both in the United States and around the world.
The APA named the Work Groups and membership for next revision, DSM-V, mandating an early draft for comment in 2009 and completion scheduled for May 2012.

Malaga, Andalucia, Spain. There has been relatively little systematic study of the effects of long-term cross-sex hormone therapy in male-to-female (M2F) and female-to-male (F2M) transsexuals [cf. sidebar]. Now, this is beginning to change. A research team from Hospital Regional Universitario Carlos Haya [N1] studied changes in the serum uric acid (urate) levels. Uric acid, an organic compound, is produced in large quantities by the normal human metabolism.
Ordinarily, people can ha... |

 | Leuven, Belgium. Images of a sexy women tend to sharpen a man's sexual appetite. But what then? Theoretically, a general reward system may give rise to non-specific effects: exposure to hot stimuli from one domain may thus affect decisions in a different domain. Studies in neuroscience have demonstrated that erotic stimuli activate the same reward circuitry that processes monetary and drug rewards. So, when a man views erotic stimuli, how does it affect his decisions in the other spheres ... |

 | New Haven and Greenwich, CT, USA. Human beings naturally wonder how others might perceive our appearance — and to what extent that might imply estimates by others of the the state of our feelings. Do the indicators suggest we are withdrawn or hostile (e.g., do we look tired or angry)? Our comfort in social situations might well depend on the answer to that question. Recent research suggests that looking tired or angry may have more to do with facial aesthetics than how we actually feel.

 | London, UK. To reinvigorate medicine and provide a useful information tool for clinicians and patients
Why would anybody want to publish a journal that is a mountain of case reports? Aren't case reports scientifically discredited? And why in particular would an old stager like me, once editor of the BMJ and strongly associated with evidence-based medicine, want to be the Editor-in-Chief of such a journal [1]?
These are questions that I've had to answer to my own satisfactio... |

 | London, UK. A journal that wants to accept not reject and to include patients as authors as much as possible
Cases Journal will publish any case report that is authentic, understandable, and ethical. The report doesn't have to be original or "important," and we hope eventually to publish tens of thousands of case reports a year. The accompanying editorial discusses what we hope to achieve with this new journal.
This editorial explains our editorial processes.

 | Rochester, MN, USA. Are the health needs of women adequately addressed by medical research as it is currently conducted? Researchers say a growing body of evidence shows important differences between men and women must be addressed by medical research, including how they respond to treatment and the long-term outcomes. Australian researchers and two cardiologists examine this question in the Mayo Clinic Proceedings, published by Mayo Foundation for Medical Education and Research.

 | New Haven, CT, USA. The naturally occurring female sex hormone estradiol plays an important role in maintaining skeletal health by balancing the ongoing processes of bone resorption and bone formation that normally occur throughout life.
Restoring estrogen levels after menopause helps to mitigate some of the more harmful side effects of hormone loss that generally occur during aging.
Researchers have now discovered that cells on their way to forming bone also produce an est... |

The manual contains a listing of psychiatric disorders, diagnostic codes, information on the prevalence of each dis... |

 | Berkeley, CA, USA. Standard magnetic resonance imaging (MRI) has found increasing usefulness for research and acceptance as a diagnostic tool, but it cannot meet the more stringent requirements of current needs. The relatively low sensitivity of standard MRI limits image resolution and patients must remain motionless for long periods of time inside noisy, claustrophobic machines. However, a promising new MRI advance is in the laboratory and nearly ready for wider use.

 | San Francisco, CA, USA. Atrazine, a common weedkiller in the U.S., already suspected of causing sexual abnormalities in frogs and fish, has now been found to alter hormonal signaling in human cells. The herbicide is the second most widely used weedkiller in the U.S., applied to corn and sorghum fields throughout the Midwest and also spread on suburban lawns and gardens. It was banned in Europe after studies linked the chemical to endocrine disruptions in fish and amphibians.

 | Providence, RI, USA. Researchers have identified problems with applying the Structured Clinical Interview for DSM-IV (SCID), reporting that fewer than half the patients previously diagnosed with bipolar disorder received a diagnosis based on a comprehensive, psychiatric diagnostic interview — the SCID. The study in the Journal of Clinical Psychiatry concludes that while recent reports indicate that there is a problem with underdiagnosis of bipolar disorder, an equal if not greater pr... |

Montreal, Quebec, CAN. Researchers performed the world’s first totally automated administration of an anesthetic. Nicknamed “McSleepy,” the new system administers drugs for general anesthesia and monitors their separate effects completely automatically, with no manual intervention. The anesthetic technique was used on a patient who underwent a partial nephrectomy, a procedure that removes a kidney tumor while leaving the non-cancerous part of the kidney intact, over a period of three hours a... |
