This phenomenon — in which someone feels better after receiving fake treatment — was once dismissed as an illusion. People who are ill often improve regardless of the treatment they receive. But neuroscientists are discovering that in some conditions, including pain, placebos create biological effects similar to those caused by drugs.

a key ingredient is expectation: The greater our belief that a treatment will work, the better we’ll respond.
-
Placebo effects in pain are so large, in fact, that drug manufacturers are finding it hard to beat them. Finding ways to minimize placebo effects in trials, for example by screening out those who are most susceptible, is now a big focus for research. But what if instead we seek to harness these effects? Placebos might ruin drug trials, but they also show us a new approach to treating pain.

The Increasing Significance of the Decline of Men - The New York Times - 0 views
-
At one end of the scale, men continue to dominate.
-
But at the other end of the scale, men of all races and ethnicities are dropping out of the work force, abusing opioids and falling behind women in both college attendance and graduation rates.
-
From 1979 to 2007, seven percent of men and 16 percent of women with middle-skill jobs lost their positions, according to the Dallas Fed study. Four percent of these men moved to low-skill work, and 3 percent moved to high-skill jobs. Almost all the women, 15 percent, moved into high-skill jobs, with only 1 percent moving to low-skill work.

I think this research is very interesting. It takes a different perspective when discussing gender issues. It notices that there are actually a decline of men in the society. Although there are still wage inequality and other gender problems that women are usually in disadvantages, men are having more and more disadvantages now as the the society shift from physical work to mental work. As the society evolved, the social structure also evolves. Gender equality means we should put equal attention to all genders (there are more than two). --Sissi (3/16/2017)
A Medication-Assisted Treatment For Meth Addiction Shows Promise : Shots - Health News ... - 0 views
-
For the first time, a medication regime has been found effective for some patients with meth addiction in a large, placebo-controlled trial.
-
Unlike opioid addiction, for which medication-assisted treatment is the standard of care, no medication has been approved by the Food and Drug Administration for use with meth.
-
patients in clinics around the U.S. suffering from methamphetamine use disorder were treated for 12 weeks with a combination of medications — naltrexone and bupropion — or placebo.

Phantom limb pain: A literature review - 0 views
-
. The purpose of this review article is to summarize recent researches focusing on phantom limb in order to discuss its definition, mechanisms, and treatments.
-
The incidence of phantom limb pain has varied from 2% in earlier records to higher rates today. Initially, patients were less likely to mention pain symptoms than today which is a potential explanation for the discrepancy in incidence rates. However, Sherman et al.4 discuss that only 17% phantom limb complaints were initiated treated by physicians. Consequently, it is important to determine what constitutes phantom pain in order to provide efficacious care. Phantom pain is pain sensation to a limb, organ or other tissue after amputation and/or nerve injury.5 In podiatry, the predominant cause of phantom limb pain is after limb amputation due to diseased state presenting with an unsalvageable limb. Postoperative pain sensations from stump neuroma pain, prosthesis, fibrosis, and residual local tissue inflammation can be similar to phantom limb pain (PLP). Patients with PLP complain of various sensations including burning, stinging, aching, and piercing pain with changing warmth and cold sensation to the amputated area which waxes and wanes.6 Onset of symptoms may be elicited by environmental, emotional, or physical changes.

The human body encompasses various neurologic mechanisms allowing reception, transport, recognition, and response to numerous stimuli. Pain, temperature, crude touch, and pressure sensory information are carried to the central nervous system via the anterolateral system, with pain & temperature information transfer via lateral spinothalamic tracts to the parietal lobe. In detail, pain sensation from the lower extremity is transported from a peripheral receptor to a first degree pseudounipolar neurons in the dorsal root ganglion and decussate and ascend to the third-degree neurons within the thalamus.7 This sensory information will finally arrive at the primary sensory cortex in the postcentral gyrus of the parietal lobe which houses the sensory homunculus.8 It is unsurprising that with an amputation that such an intricate highway of information transport to and from the periphery may have the potential for problematic neurologic developments.
