Birth then and now - Lumley, Judith
Halfway through the 20th century, views on pain in labour encompassed almost everything from women's self-blame to blaming nurses, midwives, doctors or partners for 'bad experiences'. Soon after that, giving birth came to be seen in some settings and by some caregivers as a 'natural' and thus benign event which women could 'master'. In their recent systematic review of women's expectations and experiences of pain relief in labour, Joanne Lally, Madeleine Murtagh, Sheila Macphail, and Richard Thomson show that there is wide variation in women's expectations and knowledge about the first birth. This systematic review provides us with...

Helping editors, peer reviewers and authors improve the clarity, completeness and transparency of reporting health research - Moher, David; Simera, Iveta; Schulz, Kenneth F; Hoey, John; Altman, Douglas G
Inadequate reporting is problematic for several reasons. If authors do not provide sufficient details concerning the conduct of their study, readers are left with an incomplete picture of what was done. As such, they are not able to judge the merits of the results and interpret them. The EQUATOR Network is a new initiative aimed at improving the clarity and transparency of reporting health research.

MicroRNAs: regulators of oncogenesis and stemness - Papagiannakopoulos, Thales; Kosik, Kenneth S
MicroRNAs (miRNAs) are essential post-transcriptional regulators that determine cell identity and fate. Aberrant expression of miRNAs can lead to diseases, including cancer. Expression of many miRNAs in the de-differentiated brain tumor cancer stem cells resembles that of neural stem cells. In this issue of BMC Medicine, Silber et al provide evidence of the expression of such miRNAs and their potential to mediate differentiation in both stem cell populations. In this commentary, we discuss the known functions of miRNAs in cancer and stem cells, their therapeutic potential and how the findings of Silber et al provide insight into the role of...

Commentary on strategies for switching antipsychotics - Davis, John M; Leucht, Stefan
Both the new generation of antipsychotics and the more traditional antipsychotic drugs produce an important and meaningful improvement in patients with schizophrenia, but most patients are neither cured nor free of symptoms. As a consequence, it is common to switch from one drug to another in the hope of obtaining a better response. All antipsychotic drugs produce some side effects, so switching can also be a tolerance issue. There are reports in the literature on the tactics of switching: abrupt discontinuation, cross tapering, starting a patient on a new drug while continuing with the old drug until the new drug...
