Folfirinox vs. Gemcitabine + Nab-Paclitaxel as the First-Line Treatment for Pancreatic Cancer: A Systematic Review and Meta-Analysis.

Background: The efficacy and safety of Folfirinox (FFX) or gemcitabine + nab-paclitaxel (GnP) to be used as the first-line drugs for pancreatic cancer (PC) is yet to be established. We conducted an analysis of retrospective studies to assess the efficacy and safety of these two regimens by comparing their survival and safety outcomes in patients with PC. Methods: We conducted an extensive review of two electronic databases from inception till February 2023 to include all the relevant studies that compared FFX with GnP published and unpublished work. Retrospective studies were only included. Overall survival (OS) and progression-free survival (PFS) were pooled using hazard ratios (HRs), while objective response rate (ORR) and safety outcomes were pooled using odds ratios (ORs) with 95% confidence interval (CI) using the random effects model. Results: A total of 7,030 patients were identified in a total of 21 articles that were shortlisted. Pooled results concluded that neither FFX nor GnP was associated to increase the OS time (HR: 0.93, 95% CI: 0.83 - 1.04; P = 0.0001); however, FFX was more likely associated with increased PFS when compared to GnP (HR: 0.88, 95% CI: 0.81 - 0.97; P < 0.0001). ORR proved to be non-significant between the two regimens (OR: 0.90, 95% CI: 0.64 - 1.27; P = 0.15). Safety outcomes included neutropenia, anemia, thrombocytopenia and diarrhea. GnP was more associated with diarrhea (OR: 1.96, 95% CI: 1.22 - 3.15; P = 0.001), while FFX was seen to cause anemia (OR: 0.70, 95% CI: 0.51 - 0.98; P = 0.10) in PC patients. Neutropenia and thrombocytopenia were in-significant in the two drug regimens (OR: 1.10, 95% CI: 0.92 - 1.31; P = 0.33 and OR: 0.83, 95% CI: 0.60 - 1.13; P = 0.23, respectively). Conclusion: FFX and GnP showed a significant difference in increasing the PFS, while no difference was observed while measuring OS. Safety outcomes showed that FFX and GnP shared similar safety profiles as FFX was associated with hematological outcomes, while GnP was more associated with non-hematological outcomes.

The association of antibiotic exposure with new-onset inflammatory bowel disease: A systematic review and meta-analysis.

INTRODUCTION: The role of antibiotics in the development of inflammatory bowel disease (IBD) remains controversial, primarily due to conflicting data from individual studies. We conduct a systematic review and meta-analysis to study the effect of antibiotic exposure on IBD development. METHODOLOGY: The MEDLINE and Cochrane CENTRAL databases were queried from their inception to April 2021 for published articles studying the association between antibiotic exposure and new-onset IBD. Our analysis was stratified by timing of antibiotic exposure - exposure in childhood and any lifetime exposure. Adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CIs) from each study were pooled using a random-effects model. RESULTS: 10 case-control studies and 2 cohort studies (N = 29,880 IBD patients and N = 715,548 controls) were included. Patients with Crohn's Disease (CD), compared with controls, were associated significantly with antibiotic exposure in childhood and any lifetime exposure to antibiotics (OR 1.52 [1.23-1.87]; p<0.00001). Patients with Ulcerative Colitis (UC), compared with controls, reported non-significant association with antibiotic exposure in childhood and any lifetime exposure. (OR 1.11 [0.93-1.33]; p = 0.25) CONCLUSION: This meta-analysis suggests that exposure to antibiotics significantly increases the odds of developing CD and IBD. These findings re-emphasize the importance of cautious and judicious use of antibiotics.

Impact of liver cirrhosis on ST-elevation myocardial infarction related shock and interventional management, a nationwide analysis.

BACKGROUND: Critical care is rapidly evolving with significant innovations to decrease hospital stays and costs. To our knowledge, there is limited data on factors that affect the length of stay and hospital charges in cirrhotic patients who present with ST-elevation myocardial infarction-related cardiogenic shock (SRCS). AIM: To identify the factors that increase inpatient mortality, length of stay, and total hospital charges in patients with liver cirrhosis (LC) compared to those without LC. METHODS: This study includes all adults over 18 from the National Inpatient Sample 2017 database. The study consists of two groups of patients, including SRCS with LC and without LC. Inpatient mortality, length of stay, and total hospital charges are the primary outcomes between the two groups. We used STATA 16 to perform statistical analysis. The Pearson's chi-square test compares the categorical variables. Propensity-matched scoring with univariate and multivariate logistic regression generated the odds ratios for inpatient mortality, length of stay, and resource utilization. RESULTS: This study includes a total of 35798453 weighted hospitalized patients from the 2017 National Inpatient Sample. The two groups are SRCS without LC (n = 758809) and SRCS with LC (n = 11920). The majority of patients were Caucasian in both groups (67% vs 72%). The mean number of patients insured with Medicare was lower in the LC group (60% vs 56%) compared to the other group, and those who had at least three or more comorbidities (53% vs 90%) were significantly higher in the LC group compared to the non-LC group. Inpatient mortality was also considerably higher in the LC group (28.7% vs 10.63%). Length of Stay (LOS) is longer in the LC group compared to the non-LC group (9 vs 5.6). Similarly, total hospital charges are higher in patients with LC ($147407.80 vs $113069.10, P ≤ 0.05). Inpatient mortality is lower in the early percutaneous coronary intervention (PCI) group (OR: 0.79 < 0.11), however, it is not statistically significant. Both early Impella (OR: 1.73 < 0.05) and early extracorporeal membrane oxygenation (ECMO) (OR: 3.10 P < 0.05) in the LC group were associated with increased mortality. Early PCI (-2.57 P < 0.05) and Impella (-3.25 P < 0.05) were also both associated with shorter LOS compared to those who did not. Early ECMO does not impact the LOS; however, it does increase total hospital charge (addition of $24717.85, P < 0.05). CONCLUSION: LC is associated with a significantly increased inpatient mortality, length of stay, and total hospital charges in patients who develop SRCS. Rural and Non-teaching hospitals have significantly increased odds of extended hospital stays and higher adjusted total hospital charges. The Association of LC with worse outcomes outlines the essential need to monitor these patients closely and treat them early on with higher acuity care. Patients with early PCI had both shorter LOS and reduced inpatient mortality, while early Impella was associated with increased mortality and shorter LOS. Early ECMO is associated with increased mortality and higher total hospital charges. This finding should affect the decision to follow through with interventional management in this cohort of patients as it is associated with poor outcomes and immense resource utilization.
