The Lancet profiles Lisa Bero's "path of most resistance"
Health policy expert Lisa Bero, PhD, is hailed in the latest issue of The Lancet for tackling hot-button subjects such as financial biases in drug research.

Pregnancy Monitoring After Tubal Reversal Surgery
Another Tubal Reversal Message Board member writes about getting another positive pregnancy test after successful tubal reversal surgery. Early pregnancy monitoring is an important step when trying to conceive after reversing tubes. The reason for early pregnancy monitoring is to prevent a tubal pregnancy from progressing to the point of rupturing the fallopian tube. Because of the risk of tubal pregnancy (approximately 10-15 percent) following tubal reversal surgery, it is important to notify your obstetrician-gynecologist and Chapel Hill Tubal Reversal Center as soon as you have a positive pregnancy test. The Pregnancy Report Form can be filled out online and a staff member will follow-up within 24 hours. The HCG (pregnancy hormone) levels should be drawn twice a week until the level has...

Mother-Child Role Reversal? Not So Simple.
Psychologist Paula J. Caplan is caring for her mother, but many mis-characterize her situation. They imagine role reversal, or the recent infantilization of the mother. In reality, care work is much more nuanced than this. She writes of the ways in which her mother still cares for her, even as she is playing a guardian role.read more (Source: Psychology Today Parenting Center)MedWorm Message: Please support the Doctors In Chains campaign for the medics tortured and sentenced for up to 15 years in Bahrain. #FreeDoctors

Et cetera: non-fiction roundup – reviews
Dignity by Michael Rosen, The Shrink and the Sage by Julian Baggini and Antonia Macaro and iDisorder by Larry D Rosen, with Nancy A Cheever and L Mark CarrierDignity by Michael Rosen (Harvard, £16.95)The idea of "dignity" has over the last century become enshrined in law, but what exactly does it mean? It could be, Rosen observes, a social "rank or status", or the inviolable moral core of our humanity, or "measured and self-possessed behaviour", or the endurance of suffering without loss of self-control, or the right to be treated with respect, or – as Schopenhauer and Nietzsche thought – just a vacuous hurrah-word. (It's also a ship, in a song by Deacon Blue, but let's leave that for now.) The author reads Kant and some modern popes, and discusses a French dwarf fighting for the righ...

Pregnancy: weight control cuts complications
Conclusion This study has found that dieting during pregnancy to maintain a healthy weight is safe, effective and has no consequential effect on the baby’s birth weight, a factor which many women worry about. It’s important to correct some of the inaccurate news coverage of this research. The research highlights the importance of eating healthily during pregnancy, but does not mean that all pregnant women should be put on diets. Nor does it recommend a reversal of the current advice that women should not eat for two, which has long been discouraged. While putting on too much weight can affect a woman’s health and increase the risk of complications, gaining too little weight can also cause problems and mean the body is not storing enough fat. The current advice is not to go on a weigh...

Doctor from Boston Children’s documents difficulties of life in the Congo
Chris Carpenter and patient Chris Carpenter, MD, of Boston Children’s Hospital’s Global Pediatrics Program (GPP), sees the world a little differently than most people.

His documentary film, “Born in Goma” captures his time in the war-ravaged Democratic Republic of Congo, focusing on three special patients— Isaac, Gisele and Dieume—trying to survive in the midst of extreme poverty and violence. Be aware, some of the following images are somewhat graphic in nature. After finishing medical school and his pediatric residency, Carpenter was ready to embark o...
