Meta-Analysis Review
OBJECTIVE
Transcatheter aortic valve replacement (TAVR) is a successful treatment for aortic stenosis (AS) patients, and previous studies indicate favorable outcomes for those with concomitant aortic stenosis and transthyretin-associated cardiac amyloidosis (TTRCA-AS). However, the impact of TAVR on more adverse outcomes in TTRCA-AS patients compared to those with AS alone is still uncertain, with conflicting findings reported in the literature.
METHODS
PubMed and Scopus were extensively searched from inception till August 2021. Studies were included if they reported data for prevalence and outcomes including mortality and cardiovascular-related hospitalization events in TTRCA-AS patients referred for TAVR. The data for these outcomes were pooled using a random effects model and forest plots were created.
RESULTS
After initially screening 146 articles, 6 were shortlisted for inclusion in our analysis. Pooled analysis demonstrated a 13.3% [95% CI: 10.9-16.5; p = 0.307] prevalence of TTRCA in patients with AS undergoing TAVR. The incidence of mortality and cardiovascular (CV) hospitalization in patients with TTRCA-AS undergoing TAVR were 28.3% [95% CI: 18.7-39.0, p = 0.478] and 21.1% [95% CI: 10.2-34.5, p = 0.211], respectively.
CONCLUSION
The overall pooled TTRCA-AS prevalence was reported to be 13.3% in AS patients who underwent TAVR. Furthermore, transthyretin-associated CA was found to be associated with an increased risk of mortality and hospitalization. Large patient population studies are required to assess the safety and efficacy of TAVR in TTRCA-AS patients, as current research report data from small patient cohorts.

Meta-Analysis
Small peptide formulas versus standard polymeric formulas for enteral nutrition in critically ill patients with acute gastrointestinal injury (AGI) have been a topic of debate. A systematic review and meta-analysis were conducted to compare their clinical and nutritional outcomes. Relevant studies from January 1980 to June 2022 were searched in PubMed, Cochrane, and Embase databases. Randomized controlled trials involving AGI grade I-IV patients were included, while children, non-AGI patients, and non-critically ill patients were excluded. Results indicated no significant difference in all-cause mortality. Patients receiving small peptide formulas showed higher daily protein intake, greater albumin growth, and higher prealbumin levels. They also had shorter lengths of stay in the intensive care unit and hospital. Conversely, patients receiving standard polymeric formulas had a higher daily calorie intake. In conclusion, the choice of formula may not affect mortality in critically ill patients with AGI. Small peptide formulas were more conducive to increase daily protein intake, decrease intensive care unit and hospital length of stay. Further large-scale randomized controlled trials evaluating the effects of these two nutritional formulas on clinical and nutritional outcomes in critically ill patients with AGI are needed to confirm these results.

Meta-Analysis
The correlation between pre-operative serum pre-albumin and surgical site infection (SSI) has been the focus of many studies. However, existing literature presents conflicting evidence on this association. Therefore, this meta-analysis was conducted to determine the significance of low serum pre-albumin as a prognostic factor SSI, and to assess the potential utility of pre-albumin in predicting SSI. A comprehensive literature search and analysis was conducted in PubMed, Web of Science, Cochrane of Library, Scopus, Embase, and Google Scholar databases through August 2022 to identify studies reporting low pre-operative serum pre-albumin levels in patients undergoing surgery and their association with SSIs. The pooled risk estimates were shown in odds ratio with 95% confidence interval. The random effect model was used according to the test of heterogeneity among studies. Subgroup analyses and sensitivity analyses were performed to identify the possible sources of heterogeneity. This meta-analysis was prospectively registered in the PROSPERO database (number: CRD42022376167). Nine studies involving 5,306 patients were eligible. The results demonstrated an association between low pre-operative serum pre-albumin levels and a higher probability of developing SSI (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.28-3.26). Our findings suggest that low serum pre-albumin level may serve as an independent and valuable predictor of SSI. These results provide important insights for clinicians in identifying high-risk patients and implementing preventive measures.
