The Role and Effect of Multimodal Prehabilitation Before Major Abdominal Surgery: A Systemic Review and Meta-Analysis.

BACKGROUND: For patients undergoing abdominal surgery, multimodal prehabilitation, including nutrition and exercise interventions, aims to optimize their preoperative physical and physiological capacity. This meta-analysis aims to explore the impact of multimodal prehabilitation on surgical and functional outcomes of abdominal surgery. METHODS: Medline, Embase and CENTRAL were searched for articles about multimodal prehabilitation in major abdominal surgery. Primary outcomes were postoperative complications with a Clavien-Dindo score ≥3, and functional outcomes, measured by the 6-Minute Walking Test (6MWT). Secondary outcome measures included the quality-of-life measures. Pooled risk ratio (RR) and 95% confidence interval (CI) were estimated, with DerSimonian and Laird random effects used to account for heterogeneity. RESULTS: Twenty-five studies were included, analysing 4,210 patients across 13 trials and 12 observational studies. Patients undergoing prehabilitation had significantly fewer overall complications (RR = 0.879, 95% CI 0.781-0.989, p = 0.034). There were no significant differences in the rates of wound infection, anastomotic leak and duration of hospitalization. The 6MWT improved preoperatively in patients undergoing prehabilitation (SMD = 33.174, 95% CI 12.674-53.673, p = 0.005), but there were no significant differences in the 6MWT at 4 weeks (SMD = 30.342, 95% CI - 2.707-63.391, p = 0.066) and 8 weeks (SMD = 24.563, 95% CI - 6.77-55.900, p = 0.104) postoperatively. CONCLUSIONS: As preoperative patient optimization shifts towards an interdisciplinary approach, evidence from this meta-analysis shows that multimodal prehabilitation improves the preoperative functional capacity and reduces postoperative complication rates, suggesting its potential in effectively optimizing the abdominal surgery patient. However, there is a large degree of heterogenicity between the prehabilitation interventions between included articles; hence results should be interpreted with caution.

The Impact and Applications of Social Media Platforms for Public Health Responses Before and During the COVID-19 Pandemic: Systematic Literature Review.

BACKGROUND: Social media platforms have numerous potential benefits and drawbacks on public health, which have been described in the literature. The COVID-19 pandemic has exposed our limited knowledge regarding the potential health impact of these platforms, which have been detrimental to public health responses in many regions. OBJECTIVE: This review aims to highlight a brief history of social media in health care and report its potential negative and positive public health impacts, which have been characterized in the literature. METHODS: We searched electronic bibliographic databases including PubMed, including Medline and Institute of Electrical and Electronics Engineers Xplore, from December 10, 2015, to December 10, 2020. We screened the title and abstracts and selected relevant reports for review of full text and reference lists. These were analyzed thematically and consolidated into applications of social media platforms for public health. RESULTS: The positive and negative impact of social media platforms on public health are catalogued on the basis of recent research in this report. These findings are discussed in the context of improving future public health responses and incorporating other emerging digital technology domains such as artificial intelligence. However, there is a need for more research with pragmatic methodology that evaluates the impact of specific digital interventions to inform future health policy. CONCLUSIONS: Recent research has highlighted the potential negative impact of social media platforms on population health, as well as potentially useful applications for public health communication, monitoring, and predictions. More research is needed to objectively investigate measures to mitigate against its negative impact while harnessing effective applications for the benefit of public health.
