A SIMPLE Performance Assessment of Bariatric Procedures and Post-operative Weight Regain.

Background: When assessing and reporting the performance of bariatric procedures, longitudinal total weight loss % (TWL%) is the preferred method of choice. This averages out significant individual weight regains. Due to no assessment of individual weight trajectories, numerous patients with weight recidivism are missed in the overall assessment of the applied procedures.

Paternal organic solvent exposure and adverse pregnancy outcomes: a meta-analysis.

Background: Organic solvents are widely used, but conflicting reports exist concerning paternal exposure and adverse pregnancy outcomes. We conducted a meta-analysis to assess the risks of spontaneous abortions (SAs) and major malformations (MMs) after paternal exposure to organic solvents.

Methods: Medline, Toxline, Reprotox, and Embase from 1966 to 2003 were searched.
