Adjuvant and neoadjuvant therapy with cyclin-dependent kinase 4 and 6 inhibitors in hormone receptor-positive, human epidermal growth factor receptor 2-negative early breast cancer: a systematic review and meta-analysis.
Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors have shown advantages in hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. This study aimed to evaluate the efficacy and safety of CDK4/6 inhibitors combined with endocrine therapy (ET) in patients with HR+, HER2- early breast cancer. The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for randomized controlled trials (RCTs) related to CDK4/6 inhibitors combined with ET. Literature conforming to the research content was identified according to the inclusion and exclusion criteria. The efficacy endpoints included invasive disease-free survival (IDFS), distant relapse-free survival (DRFS), and overall survival (OS) with adjuvant therapy. The efficacy endpoint of neoadjuvant therapy was complete cell cycle arrest (CCCA). The safety outcomes included the incidence of adverse events (AEs) and grade 3-4 hematological and non-hematological AEs. Data analysis was performed using Review Manager software (version 5.3). A statistical model (fixed-effects model or random-effects model) was selected based on the level of heterogeneity, and a sensitivity analysis was performed if strong heterogeneity existed. Subgroup analyses were performed based on the baseline patient characteristics. Nine articles (including six RCTs) were included in the study. In adjuvant therapy, compared with the control group, CDK4/6 inhibitors combined with ET showed no statistically significant difference in IDFS (hazard ratio = 0.83, 95% confidence interval (CI) = 0.64-1.08, P = 0.17) and DRFS (hazard ratio = 0.83, 95% CI = 0.52-1.31, P = 0.42). In neoadjuvant therapy, CDK4/6 inhibitors combined with ET significantly improved CCCA compared with the control group (odds ratio = 9.00, 95% CI = 5.42-14.96, P < 0.00001). In terms of safety, the combination treatment group had a significantly increased incidence of grade 3-4 hematological AEs in patients, especially grade 3-4 neutropenia (risk ratio (RR) = 63.90, 95% CI = 15.44-264.41, P < 0.00001) and grade 3-4 leukopenia (RR = 85.89, 95% CI = 19.12-385.77, P < 0.00001), with statistically significant differences. In patients with HR+, HER2- early breast cancer, the addition of CDK4/6 inhibitors may prolong IDFS and DRFS in adjuvant therapy, especially in high-risk patients. Further follow-up is needed to establish whether OS can be improved with CDK4/6 inhibitors plus ET. CDK4/6 inhibitors also showed effective anti-tumor proliferation activity in neoadjuvant therapy. Regular monitoring of routine blood tests in patients using CDK4/6 inhibitors is essential.

Meta-Analysis Review
BACKGROUND
This study aimed to explore the efficacy and safety of trastuzumab plus tyrosine kinase inhibitors (TKIs) compared with those of trastuzumab monotherapy in patients with human epidermal growth factor receptor (HER2)-positive breast cancer.
METHODS
The PubMed, Embase, Cochrane, and Web of Science databases were systematically searched for relevant articles from inception until September 2022. The primary outcomes were overall survival (OS) and progression-free survival (PFS). Subgroup analyses were performed based on disease status, TKI type, and hormone receptor status.
RESULTS
Sixteen studies were included in the current analysis. Trastuzumab plus TKI significantly improved OS and PFS compared to trastuzumab monotherapy. In the neoadjuvant setting, trastuzumab plus TKI significantly increased the pathologic complete response (pCR) rate compared to trastuzumab monotherapy. Moreover, a higher objective response rate (ORR) was observed with trastuzumab plus TKI. Patients who received the combination therapy had a higher incidence of discontinuation, all-grade diarrhea, and grade ≥ 3 diarrhea.
CONCLUSIONS
Trastuzumab plus TKI was better than trastuzumab monotherapy for treating different stages of HER2-positive breast cancer. The safety of trastuzumab plus TKI anti-HER2 therapy was controllable. The different efficacies of TKIs combined with trastuzumab may be related to the mechanism of action of the different TKIs, needing further investigations.

Meta-Analysis
BACKGROUND
RAS mutations affect prognosis in patients with metastatic colorectal cancer (mCRC) and have been identified as strong negative predictive markers for anti-epidermal growth factor receptor monoclonal antibody (anti-EGFR mAb) therapy, but many tumors containing wild-type RAS genes still do not respond to these therapies. Some additional biomarkers may have prognostic or predictive roles, but conclusions remain controversial.
METHODS
We performed a meta-analysis and systematic review of randomized controlled trials comparing anti-EGFR mAb therapy with alternative therapy that investigated the prognostic and predictive impact of additional biomarkers in RAS wild-type (wt) mCRC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) for progression-free survival (PFS) and overall survival (OS) and odds ratios (ORs) for objective response rate (ORR) were calculated. The prognostic value of biomarkers was investigated by separately pooling HR and OR for different treatment groups in an individual study. The predictive value was assessed by pooling study interactions between treatment effects and biomarker subgroups.
RESULTS
Thirty publications reporting on eighteen trials were selected, including a total of 13,507 patients. In prognostic analysis, BRAF mutations were associated with poorer PFS [HRs = 3.76 (2.47-5.73) and 2.69 (1.82-3.98)] and OS [HRs = 2.66 (1.95-3.65) and 2.45 (1.55-3.88)] in both the experimental and control arms; low miR-31-3p expression appeared to have longer PFS and OS. In terms of predictive effect, a lack of response to anti-EGFR therapy was observed in patients with BRAF mutant tumors (P < 0.01 for PFS). Patients with tumors with any mutation in the KRAS/NRAS/BRAF/PIK3CA gene also showed similar results compared with all wild-type tumors (P for PFS, OS, and ORR were < 0.01, < 0.01 and 0.01, respectively). While low miR-31-3p expression could predict PFS (P = 0.01) and OS (P = 0.04) benefit. The prognostic and predictive value regarding PIK3CA mutations, PTEN mutations or deletions, EGFR, EREG/AREG, HER2, HER3, and HER4 expression remains uncertain.
CONCLUSIONS
In RAS wt mCRC patients receiving EGFR-targeted therapy, BRAF mutation is a powerful prognostic and therapy-predictive biomarker, with no effect found for PIK3CA mutation, PTEN mutation or deletion, but the combined biomarker KRAS/NRAS/BRAF/PIK3CA mutations predict resistance to anti-EGFR therapy. Low miR-31-3p expression may have positive prognostic and therapy predictive effects. Evidence on the prognostic and predictive roles of EGFR and its ligands, and HER2/3/4 is insufficient.

Review
Efficacy and safety of tirzepatide, dual GLP-1/GIP receptor agonists, in the management of type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 are the main incretin hormones, and be responsible for the insulinotropic incretin effect. The addition of a GIP agonist to a GLP-1agonist has been hypothesized to significantly potentiate the weight-losing and glycemia control effect, which might offer a new therapeutic option in the treatment of type 2 diabetes. The current meta-analysis aims to synthesize evidence of primary efficacy and safety outcomes through clinically randomized controlled trials to evaluate integrated potency and signaling properties.
METHOD
We conducted comprehensive literature searches in Cochrane Library, Web of Science, Embase and PubMed for relevant literatures investigating the efficacy and/or safety of Tirzepatide published in the English as of May 30, 2023 was retrieved. We synthesized results using standardized mean differences (SMDs) and 95% confidence intervals (95 CIs) for continuous outcomes, and odds ratios (ORs) along with 95 Cis for dichotomous outcomes. All analyses were done using Revman version 5.3, STATA version 15.1 and the statistical package 'meta'.
RESULTS
Participants treated with weekly Tirzepatide achieved HbA1c and body weight target values significantly lower than any other comparator without clinically significant increase in the incidence of hypoglycemic events, serious and all-cause fatal adverse events. However, gastrointestinal adverse events and decreased appetite events were reported more frequently with Tirzepatide treatment than with placebo/controls.
CONCLUSION
The Tirzepatide, a dual GIP/GLP-1 receptor co-agonist, for diabetes therapy has opened a new era on personalized glycemia control and weight loss in a safe manner with broad and promising clinical implications.

Meta-Analysis Review
Effect of the Dual Glucose‐Dependent Insulinotropic Peptide/Gulcagon‐like Peptide 1 Receptor Agonist Tirzepatide on Lipid Profile and Waist Circumference: A Systematic Review and Meta‐analysis.
PURPOSE
Tirzepatide, a dual glucose-dependent insulinotropic peptide and glucagon-like peptide 1 receptor agonist, has been approved by the US Food and Drug Administration for the treatment of type 2 diabetes. The purpose of this meta-analysis is to evaluate the impact of tirzepatide on lipid profile and waist circumference (WC), both of which are risk factors of cardiovascular diseases.
METHODS
The PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov databases were systematically searched for articles published from database inception to July 31, 2022. This meta-analysis included 7 randomized controlled trials with a minimum duration of 12 weeks that compared tirzepatide with placebo or other antidiabetic medications. The random-effects model was used to estimate mean differences in lipid profile and WC from baseline. The Cochrane risk-of-bias tool for randomized trials, version 2 was used to assess the outcome's risk of bias. We evaluated the evidence using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system.
FINDINGS
A total of 8 articles from 7 trials with 7151 participants were included. All 3 eligible maintenance doses of tirzepatide (5, 10, and 15 mg once a week) were effective in increasing total cholesterol (TC) (P < 0.05), HDL-C (P < 0.05), VLDL-C (P < 0.01), triglyceride (TG) (P < 0.01), and WC (P < 0.01) changes from baseline compared with control agents including placebo, semaglutide, dulaglutide, and degludec. Although the evidence for VLDL-C and TGs by GRADE were high or moderate, the evidences for TC, HDL-C, and WC were low or moderate. Only 5mg once-weekly tirzepatide (P < 0.05), not 10 or 15 mg, could induce significant alteration in LDL-C before sensitivity analysis. The evidence by GRADE was moderate.
IMPLICATIONS
Tirzepatide had superiority over placebo or other antidiabetic agents in controlling lipid and WC levels. However, the levels of evidence by GRADE varied greatly across different outcome indicators. Limitations of the study include evaluating secondary outcomes of original trials for the meta-analyses, not assessing the effect of baseline lipid-lowering therapy on lipid levels, and not exploring the bias induced by glycemic improvement and weight loss.

Meta-Analysis
BACKGROUND
Despite increasing evidence on the safety of pregnancy after anticancer treatments in breast cancer survivors, many physicians and patients remain concerned about a potential risk of pregnancy specifically in the case of hormone receptor-positive breast cancer.
MATERIALS AND METHODS
A systematic literature search of Medline, Embase and Cochrane library with no language or date restriction up to 31 March 2023 was carried out. To be included, articles had to be retrospective and prospective case-control and cohort studies as well as clinical trials comparing survival outcomes of premenopausal women with or without a pregnancy after prior diagnosis of hormone receptor-positive breast cancer. Disease-free survival (DFS) and overall survival (OS) were the outcomes of interest. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated. Study protocol is registered in PROSPERO (n. CRD42023394232).
RESULTS
Out of 7796 screened studies, 8 were eligible to be included in the final analysis. A total of 3805 patients with hormone receptor-positive invasive early breast cancer were included in these studies, of whom 1285 had a pregnancy after breast cancer diagnosis. Median follow-up time ranged from 3.8 to 15.8 years and was similar in the pregnancy and non-pregnancy cohorts. In three studies (n = 987 patients) reporting on DFS, no difference was observed between patients with and those without a subsequent pregnancy (HR 0.96, 95% CI 0.75-1.24, P = 0.781). In the six studies (n = 3504 patients) reporting on OS, patients with a pregnancy after breast cancer had a statistically significant better OS than those without a pregnancy (HR 0.46, 95% CI 0.27-0.77, P < 0.05).
CONCLUSIONS
This systematic review and meta-analysis of retrospective cohort studies provides updated evidence that having a pregnancy in patients with prior history of hormone receptor-positive invasive early breast cancer appears safe without detrimental effect on prognosis.

Meta-Analysis Review
Diabetes mellitus (DM) has been proposed to be positively associated with breast cancer (BCa) risk due to shared risk factors, metabolic dysfunction, and the use of antidiabetic medications. We conducted a systematic review and meta-analysis to evaluate the association between DM and BCa risk. We searched PubMed, Embase, and Web of Science for cohort and case-control studies assessing the association between DM and BCa published before 10 December 2021. Two reviewers independently screened the studies for inclusion, abstracted article data, and rated study quality. Random effects models were used to estimate summary risk ratios (RRs) and 95% confidence intervals (CIs). From 8396 articles identified in the initial search, 70 independent studies were included in the meta-analysis. DM was associated with an overall increased risk of BCa (RR = 1.20, 95% CI: 1.11-1.29). The 24 case-control studies demonstrated a stronger association (RR = 1.26, 95% CI: 1.13-1.40) than the 46 cohort studies (RR = 1.15, 95% CI: 1.05-1.27). Studies reporting risk by menopausal status found that postmenopausal women had an elevated risk of developing BCa (RR = 1.12, 95% CI: 1.07-1.17). No association between DM and BCa risk was observed among premenopausal women (RR = 0.95, 95% CI: 0.85-1.05). In addition, DM was associated with significantly increased risks of oestrogen receptor (ER)+ (RR = 1.09, 95% CI: 1.00-1.20), ER- (RR = 1.16, 95% CI: 1.04-1.30), and triple negative BCa (RR = 1.41, 95% CI: 1.01-1.96). The association estimate for human epidermal growth factor 2-positive BCa was also positive (RR = 1.21, 95% CI: 0.52-2.82), but the CI was wide and crossed the null. Our meta-analysis confirms a modest positive association between DM and BCa risk. In addition, our results suggest that the association between DM and BCa may be modified by menopausal status, and that DM may be differentially associated with BCa subtypes defined by receptor status. Additional studies are warranted to investigate the mechanisms underlying these associations and any influence of DM on BCa receptor expression.

Meta-Analysis Review
Plasmatic presepsin (PSP) is a novel biomarker reported to be useful for sepsis diagnosis and prognosis. During the pandemic, only few studies highlighted a possible correlation between PSP and COVID-19 severity, but results remain inconsistent. The present study aims to establish the correlation between PSP and COVID-19 severity. English-language papers assessing a correlation between COVID-19 and PSP from MEDLINE, PubMed, Google Scholar, Cochrane Library, MeSH, LitCovid NLM, EMBASE, CINAHL Plus and the World Health Organization (WHO) website, published from January 2020 were considered with no publication date limitations. Two independent reviewers performed data abstraction and quality assessment, and one reviewer resolved inconsistencies. The protocol was registered on PROSPERO (CRD42022325971).Fifteen articles met our eligibility criteria. The aggregate study population included 1373 COVID-19 patients who had undergone a PSP assessment. The random-effect meta-analysis was performed in 7 out of 15 selected studies, considering only those reporting the mean PSP levels in low- and high-severity cases (n = 707).The results showed that the pooled mean difference of PSP levels between high- and low-severity COVID-19 patients was 441.70 pg/ml (95%CI: 150.40-732.99 pg/ml).Our data show that presepsin is a promising biomarker that can express COVID-19 severity.

Review
Adiponectin replacement therapy holds the potential to benefit numerous human diseases, and ongoing research applies particular interest in how adiponectin acts against Metabolic-associated Fatty Liver Disease (MAFLD) and Nonalcoholic Steatohepatitis (NASH). However, the pharmacological limitations of the intact protein have prompted a focus on alternative options, specifically peptidic and small molecule agonists targeting the adiponectin receptor. AdipoRon is an extensively researched non-peptidic drug candidate in adiponectin replacement therapy. In turn, ADP355 is an adiponectin-based active short peptide. They have garnered significant attention due to their potential as substitutes for adiponectin. Researchers have studied AdipoRon's and ADP355's efficacy and therapeutic applications in various disease conditions. However, the effects of AdipoRon and ADP355 against NAFLD and NASH models advanced more, and no systematic review explored this area before. This systematic review was conceived to address the deficiency mentioned above and consider the lack of clinical evidence. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized. To assess the risk of bias in systematic review, The Joanna Briggs Institute (JBI) Critical Appraisal Checklist was employed. Results from pre-clinical evidence show that AdipoRon and ADP355 represent promising effects in NAFLD and NASH-related models, including reducing hepatic steatosis, modulating inflammation, improving insulin sensitivity, enhancing mitochondrial function, and protecting against liver fibrosis. While AdipoRon and ADP355 exhibit promise in pre-clinical studies and experimental models, additional clinical trials are necessary to assess their effectiveness, safety, and potential translational therapeutic potential uses in NAFLD and NASH human cases.

Arthritis Research & Therapy Jul 2023The objective of this systematic review was to assess the effects of interleukin-1β (IL-1β) inhibitors on gout flares. (Review)
Review
OBJECTIVES
The objective of this systematic review was to assess the effects of interleukin-1β (IL-1β) inhibitors on gout flares.
METHODS
Studies published between 2011 and 2022 that evaluated the effects of IL-1β inhibitors in adult patients experiencing gout flares were eligible for inclusion. Outcomes including pain, frequency and intensity of gout flares, inflammation, and safety were assessed. Five electronic databases (Pubmed/Medline, Embase, Biosis/Ovid, Web of Science and Cochrane Library) were searched. Two independent reviewers performed study screening, data extraction and risk of bias assessments (Cochrane Risk of Bias Tool 2 for randomised controlled trials [RCTs] and Downs and Black for non-RCTs). Data are reported as a narrative synthesis.
RESULTS
Fourteen studies (10 RCTs) met the inclusion criteria, with canakinumab, anakinra, and rilonacept being the three included IL-1β inhibitors. A total of 4367 patients with a history of gout were included from the 14 studies (N = 3446, RCTs; N = 159, retrospective studies [with a history of gout]; N = 762, post hoc analysis [with a history of gout]). In the RCTs, canakinumab and rilonacept were reported to have a better response compared to an active comparator for resolving pain, while anakinra appeared to be not inferior to an active comparator for resolving pain. Furthermore, canakinumab and rilonacept reduced the frequency of gout flares compared to the comparators. All three medications were mostly well-tolerated compared to their comparators.
CONCLUSION
IL-1β inhibitors may be a beneficial and safe medication for patients experiencing gout flares for whom current standard therapies are unsuitable.
