Suitability of administrative claims databases for bariatric surgery research - is the glass half-full or half-empty?
The authors assessed the availability and validity of claims-based weight-related diagnosis codes among bariatric surgery patients who underwent adjusted gastric banding, Roux-en-Y gastric bypass, or sleeve gastrectomy. They found that claims-based weight-related diagnosis codes had excellent validity before and after bariatric surgical operation but suboptimal availability after operation. Claims databases can be used for bariatric surgery studies of non-weight-related effectiveness and safety outcomes that are well-captured.

Methods for evaluating natural experiments in obesity: a systematic review.
The researchers identified studies that report effects of programs, policies, or built environment changes on obesity prevention and control and described their methods. They found many methodologically diverse natural experiments and experimental studies that reported effects of U.S. and non-U.S. programs, policies, or built environment changes on obesity prevention and control, reinforcing the need for methodological and analytic advances to strengthen evaluations of obesity prevention and control initiatives.

Advancing informed consent for vulnerable populations.
The authors suggest an innovative approach that uses low health-literacy communication strategies and visual aids to augment and potentially replace the traditional approach to informed consent. This approach involves: (1) the use of effective health communication and low-literacy techniques, (2) the use of visual aids and graphics to promote understanding and guide the reader toward key study concepts, and (3) careful attention to child dissenting behaviors.
