Bottom line:
Despite some study limitations, this is the first trial to show a mortality benefit from weight loss or obesity surgery. Careful patient selection is crucial.
More study is needed to try to ascertain if this was a simple association or cause & effect.

Bottom line:
Montelukast should be used for patients with a specific indication (allergies, asthma triggered by allergens, exercise-induced asthma), but did not show benefit as “stepdown” therapy for patients with mild persistent asthma who were well controlled with ICS.
Adding a LABA to ICS may be helpful for these patients, but studies of a longer duration are needed.

Bottom line: CTC may be a reasonable alternative to colonoscopy in patients who are otherwise unwilling to undergo optical colonoscopy, BUT…patients need to be informed as to the details of the procedure (insufflation), and the fact that they may need an optical colonoscopy with biopsy if a polyp is found

““While more evidence is needed, While more evidence is needed, particularly on long term clinical particularly on long term clinical outcomes, the data assembled in this outcomes, the data assembled in this systematic review support PHEs. We systematic review support PHEs. We hope that third party payers will as hope that third party payers will as well.”well.”
Bottom line: There is evidence to support what we all inherently know - the value of the periodic health exam.
