Association between BMI and Efficacy of SGLT2 Inhibitors in Patients with Heart Failure or at Risk of Heart Failure: A Meta-Analysis Based on Randomized Controlled Trials.

INTRODUCTION: This meta-analysis aimed to investigate the effect of SGLT2 inhibitors on the prognosis of patients with heart failure (HF) or at risk of HF across different body mass index (BMI). METHODS: We searched PubMed, Embase, Web of Science, and Cochrane Library for all randomized controlled trials comparing SGLT2 inhibitors with placebo in patients with HF or at risk of HF and extracted relevant data up to April 2023 for meta-analysis. RESULTS: A total of 29,500 patients were enrolled in the selected five studies. The results showed that patients treated with SGLT2 inhibitors had lower HF hospitalization (HHF) or cardiovascular (CV) mortality compared to those taking placebo (hazard ratio [HR] = 0.73, p < 0.001). Patients taking SGLT2 inhibitors also had a lower all-cause mortality rate than those taking placebo (HR = 0.85, p = 0.017). In BMI subgroup analysis, the HHF rate in the experimental group was lower than that in the control group at BMI ≤24.9 kg/m2, 25.0-29.9 kg/m2, and ≥30.0 kg/m2. There was no significant difference in CV mortality between the two groups at BMI ≤24.9 kg/m2 (HR = 0.91, p = 0.331) and 25.0-29.9 kg/m2 (HR = 0.92, p = 0.307). However, when the BMI was ≥30.0 kg/m2, CV mortality with SGLT2 inhibitors was lower than in the control group (HR = 0.79, p = 0.002). When patients had a BMI ≤24.9 kg/m2 (HR = 0.85, p = 0.033) and 25.0-29.9 kg/m2 (HR = 0.83, p = 0.046), the all-cause mortality was lower in the experimental group than in the control group. However, there was no significant difference between the 2 groups in patients with a BMI ≥30.0 kg/m2 (HR = 0.87, p = 0.094). CONCLUSION: SGLT2 inhibitors improve the prognosis in patients with HF or at risk of HF. This effect is affected by BMI.

The efficacy and safety of anti-EGFR target agents in patients with potentially resectable metastatic colorectal cancer: a meta-analysis of randomized controlled trials.

BACKGROUND: Adding anti-epidermal growth factor receptor (anti-EGFR) target agents to conversion therapy may improve the resection rates and survival of patients with potentially resectable metastatic colorectal cancer (mCRC). This study aims to analyze the efficacy and safety of additional anti-EGFR target agents. METHODS: A systematic search was conducted on PubMed, Web of Science, Embase, and Cochrane Library. And all relevant studies published in English before January 2023 were collected to explore the impact of additional anti-EGFR targeted agent on the efficacy and safety of patients with potentially resectable mCRC (PROSPERO: CRD42022340523, https://www.crd.york.ac.uk/PROSPERO/ ). RESULTS: This study included a total of 8 articles, including 2618 patients. The overall response rate (ORR) and R0 resection rates of the experimental group were higher than those of the control group, while there was no significant difference in progression-free survival (PFS) and overall survival (OS) between the two groups. In RAS/KRAS wild-type patients, the ORR (RR: 1.20, 95% Cl: 1.02-1.41, p = 0.03), R0 resection rate (RR: 1.60, 95% Cl: 1.17-2.20, p = 0.003), PFS (HR: 0.80, 95% Cl: 0.68-0.93, p = 0.003), and OS (HR: 0.87, 95% Cl: 0.76-0.99, p = 0.031) of the experimental group were higher than those of the control group. While in KRAS mutant patients, there was no statistical difference between the two groups in ORR, R0 resection rate, PFS, and OS. CONCLUSION: The addition of anti-EGFR targeted agents can improve the prognosis of RAS/KRAS wild-type patients with potentially resectable mCRC, while KRAS mutant patients may not benefit. In addition, the overall safety factor was controllable.

Effect of Intraperitoneal Local Anesthetics in Laparoscopic Bariatric Surgery: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: The effectiveness of intraperitoneal local anesthesia (IPLA) has been confirmed in other fields, but its use in bariatric surgery remains debatable. This study aimed to evaluate the analgesic effect of IPLA in bariatric surgery. METHODS: PubMed, Web of Science, Embase, and the Cochrane Library were searched from inception to February 2022. All randomized controlled trials (RCTs) assessing IPLA's analgesic effect in bariatric surgery were included in this study. Pain-related indicators were the outcome. RESULTS: Ten RCTs with 979 patients were included. Postoperative pain scores were significantly lower in IPLA group. Subgroup analysis demonstrated that IPLA was associated with lower pain scores in 6 h and at 24 h compared to the control group, without significant differences at 8, 12, and 48 h. Meanwhile, IPLA reduced the dose of opioids taken postoperatively. Additionally, there were no differences in adverse events between the two groups. As far as the number of postoperative analgesics used and hospital stays were concerned, our results did not show statistical differences between the two groups. CONCLUSION: IPLA can reduce postoperative pain safely and effectively, particularly during the early postoperative stage.

The effect and safety of CDK4/6 inhibitors combined endocrine therapy on HR+, HER2-breast cancer: a meta-analysis of randomized controlled trials.

INTRODUCTION: The purpose of this meta-analysis is to evaluate the efficacy and safety of cyclin-dependent kinase4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) on hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC). MATERIAL AND METHODS: A search was conducted in the PubMed, Embase, Web of Science, and Cochrane Library databases before July 2022. RESULTS: A total of 19 studies comprising 19,004 patients were eligible for this meta-analysis. This meta-analysis found that for unresectable locally advanced or metastatic HR+, HER2- BC, CDK4/6i combined with ET can significantly improve the progression-free survival (PFS) (hazard ratio = 0.59, p < 0.001), overall survival (OS) (hazard ratio = 0.77, p < 0.001), objective response rate (ORR) [risk ratio (RR) = 1.32, p = 0.001)], disease control rate (DCR) (RR = 1.10, p < 0.001), and clinical benefit response (CBR) (RR = 1.15, p = 0.001). For early HR+, HER2- BC, CDK4/6i combined with ET improved ORR (RR = 1.14, p = 0.05) and invasive disease free survival (iDFS) (hazard ratio = 0.87, p = 0.045) but had no effect on pathologic complete response (pCR) (RR = 1.75, p = 0.33), distant recurrence free survival (DRFS) (hazard ratio = 0.83, p = 0.311), and OS (hazard ratio = 1.08, p = 0.705). CONCLUSION: CDK4/6i combined with ET can improve the prognosis of patients with unresectable locally advanced or metastatic HR+, HER2- BC, but it has no obvious effect on patients with early HR+, HER2- BC. It is generally safe and manageable.

Comparison of early aggressive versus nonaggressive fluid resuscitation in acute pancreatitis: a meta-analysis.

Background: Early fluid resuscitation is one of the main therapeutic strategies for acute pancreatitis (AP). This study investigated the effects of early aggressive and nonaggressive hydration on AP. Objectives: The aim of this meta-analysis is to investigate the differences between aggressive and nonaggressive intravenous fluid resuscitation in AP. Design: This study was based on publicly available data, all of which have been extracted from previous ethically approved studies. Data sources and methods: Two authors systematically searched PubMed, Embase (via OVID), Web of Science, and Cochrane Library to find all published research before February 2023. In-hospital mortality were set as primary endpoints. Results: This meta-analysis included seven randomized controlled trials (RCTs) and eight cohort studies with 4072 individuals in nonaggressive (n = 2419) and aggressive (n = 1653) hydration groups. The results showed that patients in the nonaggressive group had a lower mortality rate than those in the aggressive hydration group [relative risks (RR), 0.66; p = 0.02]. Subgroup analysis results showed that patients in the nonaggressive hydration group had lower mortality rates in RCTs (RR, 0.39; p = 0.001), studies conducted in Eastern countries (RR, 0.63; p = 0.002), and studies with severe pancreatitis (RR, 0.65; p = 0.02). In addition, the nonaggressive hydration group had lower rates of infection (RR, 0.62; p < 0.001), organ failure (RR, 0.65; p = 0.02), and shock (RR, 0.21; p = 0.02), as well as a shorter hospital stay (weighted mean difference, -1.63; p = 0.001) than the aggressive hydration group. Conclusions: Early nonaggressive fluid resuscitation is associated with lower mortality, lower risk of organ failure and infection, and shorter hospital stays than aggressive fluid resuscitation.

Effect of Metformin on the Prognosis of Gastric Cancer Patients with Type 2 Diabetes Mellitus: A Meta-Analysis Based on Retrospective Cohort Studies.

Background: Metformin is one of the most common drugs for type 2 diabetes mellitus (T2DM) treatment. In addition, metformin intends to have a positive effect on the prognosis of several cancers. However, the therapeutic effect of metformin on gastric cancer (GC) remains controversial. This study explores and updates the therapeutic effect of metformin in GC patients with T2DM. Methods: We searched through PubMed, Embase, Web of Science, and the Cochrane Library for relevant articles by July 2022. The relationship between metformin therapy and the prognosis of GC patients with T2DM was evaluated based on the hazard ratio (HR) at a 95% confidence interval (95% CI). Overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS) were the primary outcomes analyzed. Results: Seven retrospective cohort studies with a combined 2,858 patients met the inclusion criteria. OS and CSS were reported in six studies, and PFS was reported in four studies. Pooled results showed that, compared to the nonmetformin group, the prolonged OS (HR = 0.72, p = 0.001), CSS (HR = 0.81, p = 0.001), and PFS (HR = 0.70, p = 0.008) of the experimental group may be associated with the exposure to metformin. Conclusion: Metformin may have a beneficial effect on the prognosis of GC patients with T2DM.

Transjugular intrahepatic portosystemic shunt for pyrrolidine alkaloids-induced hepatic sinusoidal obstruction syndrome: a retrospective cohort study.

BACKGROUND: This study aimed to investigate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of patients with pyrrolidine alkaloids-induced hepatic sinusoidal obstruction syndrome (PA-HSOS). METHODS: Patients diagnosed with PA-HSOS and treated in Ningbo No.2 Hospital between November 2017 and October 2022 were enlisted in this retrospective cohort study. RESULTS: This cohort comprised a total of 22 patients with PA-HSOS, of which 12 patients received TIPS treatment and 10 patients experienced conservative treatment. The median follow-up duration was 10.5 months. Baseline characteristics existed with no significant difference between the two groups. No operation failures or any TIPS-associated intraoperative complications were observed after TIPS. In the TIPS group, the portal venous pressure was substantially decreased from 25.3 ±â€…6.3 mmHg to 14.4 ±â€…3.5 mmHg after TIPS ( P  = 0.002). Compared with preoperative, the ascites after TIPS were significantly subsided ( P  = 0.001) and there existed a considerable decrease in Child-Pugh score. At the end of follow-up, 5 patients died, involving 1 in the TIPS group and 4 in the conservative treatment group. The median survival time was 13 (3-28) months in the TIPS group and 6.5 (1-49) months in the conservative treatment group, respectively. The survival analysis demonstrated that the total survival time of TIPS group was longer than that of the conservative treatment group, no statistical significance was observed ( P  = 0.08). CONCLUSION: TIPS may be a secure and effective therapeutic strategy for PA-HSOS patients who do not respond to conservative treatment.

Comparison of gastrojejunostomy to endoscopic stenting for gastric outlet obstruction: An updated Systematic Review and Meta-analysis.

BACKGROUND: This study aimed to determine the optimal intervention modality for malignant GOO by comparing clinical outcomes after Gastrojejunostomy and endoscopic stenting. METHODS: Two authors independently searched Web of Science, PubMed, Embase, and the Cochrane Library for articles before February 2021 to compare the clinical outcomes of GOO patients undergoing GJ or ES. RESULTS: This meta-analysis included 31 articles with 2444 GOO patients. Although the GJ group outperformed the ES group in technical success (OR,3.79; P = 0.003), clinical success was not significantly different between the two groups (OR,1.25; P = 0.50). The GJ group had a longer hospitalization, lower re-obstruction and lower reintervention. Moreover, GJ had a better survival than ES in the gastric cancer group (HR, 0.33; P = 0.009). However, no significant statistical difference was observed in the pancreatic cancer group (HR, 0.55; P = 0.159). CONCLUSIONS: Both GJ and ES are safe and effective intervention modalities for malignant GOO. GJ had significantly improved survival in gastric cancer patients with GOO, while no significant difference was observed between the two groups in pancreatic cancer patients with GOO.

Effect of vitamin D supplementation on the incidence and prognosis of depression: An updated meta-analysis based on randomized controlled trials.

Background: There have been several controversies about the correlation between vitamin D and depression. This study aimed to investigate the relationship between vitamin D supplementation and the incidence and prognosis of depression and to analyze the latent effects of subgroups including population and supplement strategy. Methods: A systematic search for articles before July 2021 in databases (PubMed, EMBASE, Web of Science, and the Cochrane Library) was conducted to investigate the effect of vitamin D supplementation on the incidence and prognosis of depression. Results: This meta-analysis included 29 studies with 4,504 participants, indicating that the use of vitamin D was beneficial to a decline in the incidence of depression (SMD: -0.23) and improvement of depression treatment (SMD: -0.92). Subgroup analysis revealed that people with low vitamin D levels (<50 nmol/L) and females could notably benefit from vitamin D in both prevention and treatment of depression. The effects of vitamin D with a daily supplementary dose of >2,800 IU and intervention duration of ≥8 weeks were considered significant in both prevention and treatment analyses. Intervention duration ≤8 weeks was recognized as effective in the treatment group. Conclusion: Our results demonstrate that vitamin D has a beneficial impact on both the incidence and the prognosis of depression. Whether suffering from depression or not, individuals with low vitamin D levels, dose >2,800 IU, intervention duration ≥8 weeks, and all females are most likely to benefit from vitamin D supplementation.

Efficacy of PD-1/PD-L1 inhibitors in patients with advanced gastroesophageal cancer: An updated meta-analysis based on randomized controlled trials.

Background: This study aimed to investigate the clinical efficacy of programmed death-1 receptor and ligand-1 (PD-1/PD-L1) inhibitors in gastroesophageal cancer patients and the relationship between their clinicopathological features and curative treatment effects. Methods: A systematic search was conducted for articles published before April 2022 from online databases (PubMed, EMBASE, Web of Science and the Cochrane Library). The main outcome was overall survival (OS). Results: This meta-analysis comprised 16 studies involving 9,304 participants. The results indicated that compared with chemotherapy, patients treated with PD-1/PD-L1 inhibitors had significantly improved OS (HR = 0.80; p < 0.001) but no significant improvement in progression-free survival (PFS) (p = 0.185). Subgroup analyses demonstrated that PD-1/PD-L1 inhibitors combined with chemotherapy, esophageal squamous cell carcinoma, male, Asian patients and combined positive score (CPS) ≥1 were significantly associated with better survival outcomes. Further, subgroup analysis of gender revealed that the OS of all subgroups containing male patients was significantly improved compared with chemotherapy, unlike that of female patients. In addition, the line of therapy, Lauren classification, age and eastern cooperative oncology group (ECOG) performance status were not associated with PD-1/PD-L1 inhibitors efficacy. Conclusion: The results indicated that PD-1/PD-L1 inhibitors could prolong the OS of advanced gastroesophageal cancer patients. Clinicopathological features such as therapeutic schedules, tumor types, histological type, gender, geographical region and PD-L1 expression status (CPS) seemed to be associated with survival outcomes.
