Psychological Science, a journal of the Association for Psychological Science, published a very interesting paper focusing on the genetic background of social drinking. Specific gene variants might increase the risk for extensive alcohol use or abuse when spending time with heavy-drinking peers. An excerpt from Medical News Today:
Drinking alcohol increases levels of dopamine –- a brain chemical that causes pleasure and makes us feel good. The dopamine D4 receptor gene (DRD4) has been shown to be involved in motivation of seeking out rewards. Research has suggested that carrying a specific form (or variant) of this gene –- one that includes seven or more repeats of a certain section of the gene –- may be associated with craving caused by alcohol-related cues. Psychological scientist Helle Larsen from Radboud University in The Netherlands and her colleagues wanted to investigate if this 7-repeat gene variant plays a role in how an individual responds to alcohol-related cues.
The results showed an effect between how much the confederate drank and the gene variant on volunteers’ alcohol consumption: When the confederate was seen consuming three or four drinks, carriers of the 7-repeat form of the gene drank more than twice as many glasses of alcohol than did noncarriers of the gene variant. However, when the confederate consumed only one drink, there was no difference in alcohol consumption between carriers and noncarriers. These findings suggest that individuals carrying this form of the DRD4 gene may be more sensitive than noncarriers to other people’s drinking behavior.

Times are tight and we’re all looking to save money, be it our own or someone else’s. Many will say that when it comes to the skyrocketing costs of healthcare, doctors are responsible for part of the problem.
Doctors order too many tests, either to cover ourselves in the event of a malpractice suit, or because patients pressure us, or because we genuinely believe that the tests are necessary for patient care, but in many circumstances, a cheaper option is available. We order medications that are expensive when cheaper medications are available. And psychiatrists offer care — like psychotherapy — that could be done by clinicians who are cheaper to educate and willing to work for less money. Read more »

Do you remember the visceral sensations of angst over an upcoming final exam? Or the first procedure as an independent doctor? A major presentation, perhaps?
Life’s exams test not only specific knowledge and skill, but one’s self esteem as well. And it’s the self esteem portion that creates the stomach churn, the palpitations, and the random thoughts of doom.
The future lurks over you for weeks, like a weighty backpack, or the possibility of encountering the bully on your walk home from elementary school. (For my bony self, her name was Marilyn.) Read more »

There’s a new profession in the Internet era, the so-called “Internet Content Reviewer.” These people check all of the submissions and uploads on huge social networking sites, review tens of thousands of pictures, and make sure only legal content is being uploaded to these communities.
It seems a new mental health, “social” disease is starting to spread: Internet Moderitis. An excerpt from a New York Times piece on the topic:
Ricky Bess spends eight hours a day in front of a computer near Orlando, Fla., viewing some of the worst depravities harbored on the Internet. He has seen photographs of graphic gang killings, animal abuse and twisted forms of pornography. One recent sighting was a photo of two teenage boys gleefully pointing guns at another boy, who is crying.
YouTube, a division of Google, is an exception. If a user indicates a video is inappropriate, software scans the image looking for warning signs of clips that are breaking the site’s rules or the law. Flagged videos are then sent for manual review by YouTube-employed content moderators who, because of the nature of the work, are given only yearlong contracts and access to counseling services, according to Victoria Grand, a YouTube spokeswoman.

A study published in the July PLoS Medicine is getting a lot of press for its conclusion that strong social networks are related to increased lifespan.
The meta-analysis of 148 studies involving 308,849 people found that those with stronger relationships were 50 percent more likely to survive over 7.5 years of follow-up. What’s more, the researchers reported that a lack of strong social ties is as bad healthwise as drinking or smoking, and worse than not exercising or being obese.
But although the association between strong social ties and improved longevity seems robust, other factors could be at play, and applying the findings in clinical practice could be difficult. And sorry, Facebook fanatics: Online “friendships” aren’t thought to count as much as in-person ones do. (PLoS Medicine, New York Times, TIME, The Atlantic)
