Interactions between maternal fluoxetine exposure, the maternal gut microbiome and fetal neurodevelopment in mice.

Selective serotonin reuptake inhibitors (SSRIs) are the most widely used treatment by women experiencing depression during pregnancy. However, the effects of maternal SSRI use on early offspring development remain poorly understood. Recent studies suggest that SSRIs can modify the gut microbiota and interact directly with particular gut bacteria, raising the question of whether the gut microbiome impacts host responses to SSRIs.

The maternal microbiome modulates fetal neurodevelopment in mice.

'Dysbiosis' of the maternal gut microbiome, in response to challenges such as infection, altered diet and stress during pregnancy, has been increasingly associated with abnormalities in brain function and behaviour of the offspring. However, it is unclear whether the maternal gut microbiome influences neurodevelopment during critical prenatal periods and in the absence of environmental challenges. Here we investigate how depletion and selective reconstitution of the maternal gut microbiome influences fetal neurodevelopment in mice.

Pediatric supracondylar humerus fractures: is surgeon experience a surrogate for the need of open reduction?

Although there are many factors that are likely to influence the need for open reduction and percutaneous pinning (ORPF) in the treatment of pediatric supracondylar humerus fractures (SCHFs), the role of surgeon's experience (as represented by the total number of surgically treated SCHFs) on the need for ORPF has seldom been investigated. We reviewed the data on all completely displaced, pediatric SCHFs that were treated surgically by a single, fellowship-trained, pediatric orthopedic surgeon over the first 10 years of the surgeon's clinical practice. The incidence of ORPF was calculated as the percentage of open reductions among surgically treated, completely displaced, consecutive SCHFs at any given time during the 10-year period.
