The types of bariatric surgery differentially affect the risk of developing acute pancreatitis postoperatively, such that the risk is greater in patients who undergo vertical sleeve gastrectomy vs Roux-en-Y gastric bypass surgery, according to a study. Risk factors include younger age and presence of gallstones.

NSAIDs neither prevent nor promote AMD incidence

01 Feb 2018

Nonsteroidal anti-inflammatory drugs (NSAIDs) appear to have little effect on the incidence of age-related macular degeneration (AMD), a study has found.

The study included 51,371 men from the California Men’s Health Study. Those with self-reported exposure to aspirin, ibuprofen, naproxen, valdecoxib, celecoxib and/or rofecoxib at least 3 days per week were considered NSAID users. NSAID use was categorized into former, new, longer-term and nonuse, as well as by type (any NSAIDs, aspirin and/or nonaspirin NSAID).

During an average follow-up of 7.4 years, a total of 292 (0.6 percent) cases of exudative AMD and 1,536 (3 percent) cases of nonexudative AMD were documented.

The risk of exudative AMD was found to be reduced among longer-term users of any NSAID (hazard ratio [HR], 0.69; 95 percent CI, 0.50–0.96; p=0.029). On the other hand, the risk of nonexudative AMD was lower among new users of any NSAID (HR, 0.79; 0.68–0.93; p=0.0039) and among new users of aspirin (HR, 0.82; 0.70–0.97; p=0.018). This particular trend did not persist in longer-term users.

Relationships observed between exudative or nonexudative AMD and the remaining categories of NSAID use were not significant.

Findings of the present study show that the overall impact of NSAIDs on AMD incidence is small, researchers said. “However, the lower risk of exudative AMD in longer-term NSAID users may point to a protective effect and deserves further study as a possible mechanism to modulate disease risk.”
