The Probable Impact of Soy Isoflavones in Bone Fracture Downturn: A Systematic Review

Background: There is a direct relationship between taking soy isoflavones and higher bone density, but there is a paucity of studies examining the relationship between flavonoid consumption and fracture risk. This study aimed to assess the bone fracture and its relationship to soy product intake by performing a systematic review. Methods: Scopus, PubMed, and Web of science were searched to find studies on the effect of soy isoflavones on bone fracture, without any time and language of publication restrictions. Key words of SoyMilk, soymilk, soybeans, soybean, soy, soya, Isoflavones, Isoflavone, ipriflavone, equol, genistein, daidzein, glycitin, fractures, and broken bone were used. Results: From a total of 1675 articles, 27 studies (cross-sectional studies (n=1), case-control studies (n=1), cohort (n=11), and randomized control trials (n=14)) were identified, and their quality was assessed. Eighteen studies highlighted mainly positive results in preventive influence of soy bone fractures. Two papers reported a positive effect was observed in men with cancer. No significant association was found between soy intake and bone prevention fracture in eight distinct papers. Conclusion: Intake of soy isoflavones can make a significant preventive effect on bone fracture; however, the results of some studies are controversial. Therefore, it is necessary to survey more studies to identify the relationship between isoflavones and bone fracture.

Prophylactic Endotracheal Intubation in Patients with Upper Gastrointestinal Bleeding Undergoing Endoscopy: A Systematic Review and Meta-analysis.

Background:Patients with upper gastrointestinal bleeding (UGIB) often require urgent or emergent esophagogastroduodenoscopy (EGD) and are at risk of complications such as aspiration of gastric content or blood. The role of prophylactic endotracheal intubation (PEI) in the absence of usual respiratory status-related indications is not well established.Methods:We searched Medline, EMBASE, Cochrane Library's Central Register of Controlled Trials (CENTRAL) and SCOPUS from inception through July 2017 without date or language of publication restriction. We included studies that compared PEI with usual care (UC) in patients with acute UGIB, and reported any of the following outcomes: aspiration, pneumonia, mortality and length of stay. We excluded studies in which majority of included patients required intubation due to respiratory failure or decreased level of consciousness. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the quality of evidence for each outcome.Results:We did not identify any randomized trials on this topic. We included 10 observational studies (n = 6068). We were not able to perform any adjusted analyses. PEI was associated with a significant increase in aspiration (OR 3.85, 95% CI, 1.46, 10.25; P = 0.01; I2= 56%; low-quality evidence), pneumonia (OR 4.17, 95% CI, 1.82, 9.57; P = 0.0007; I2=52%; low-quality evidence) and hospital length of stay (mean difference 0.86 days, 95% CI 0.13, 1.59; P = 0.02; I2= 0; low-quality evidence), without clear effect on mortality (OR 1.92, 95% CI, 0.71, 5.23; P = 0.2; I2= 95%; very low-quality evidence).Conclusions:Low- to very low-quality evidence from observational studies suggests that PEI in the setting of UGIB may be associated with higher rates of respiratory complications and, less likely, with increased mortality. Although the results are alarming, the lack of higher quality evidence calls for randomized trials to inform practice.
