Viral infections during pregnancy raise several clinical challenges, including birth defects in the offspring. Thus, this systematic review and meta-analysis aims to prove and highlight the risk of birth defects after first-trimester maternal influenza infection. Our systematic search was performed on 21 November 2022. Studies that reported maternal influenza infection in the first trimester and non-chromosomal congenital abnormalities were considered eligible. We used odds ratios (OR) with 95% confidence intervals (CIs) to measure the effect size. Pooled ORs were calculated with a random effects model. Heterogeneity was measured with I² and Cochran’s Q tests. We found that first-trimester maternal influenza was associated with increased odds of developing any type of birth defects (OR: 1.5, CI: 1.30–1.70). Moreover, newborns were more than twice as likely to be diagnosed with neural tube defects (OR: 2.48, CI: 1.95–3.14) or cleft lip and palate (OR: 2.48, CI: 1.87–3.28). We also found increased odds of developing congenital heart defects (OR: 1.63, CI: 1.27–2.09). In conclusion, influenza increases the odds of non-chromosomal birth defects in the first trimester. The aim of the present study was to estimate the risk of CAs in the offspring of mothers affected by first-trimester influenza infection.

Introduction: Ovarian cancer is a significant contributor to gynecological cancer-related mortality, necessitating innovative treatment strategies. This systematic review and meta-analysis aimed to assess the efficacy and safety of combining PARP inhibitors with anti-angiogenic agents (AAAs) in the treatment of ovarian cancer. Methods: This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and was registered on PROSPERO (CRD42022319461). A systematic search of three electronic databases, including MEDLINE (via PubMed), EMBASE, and Cochrane Library was conducted to identify relevant randomized controlled trials (RCT) that evaluated the efficacy and safety of the combination therapy. Subgroup analyses were based on BRCA mutation status. Meta-analysis was conducted to estimate pooled hazard ratios (HR) and risk ratios (RR) for progression-free survival (PFS) and adverse events, respectively. The combination therapy was compared to PARP inhibitors alone and to chemotherapy. Heterogeneity was assessed using Higgins and Thompson’s I² statistic where applicable. Results: Seven RCTs involving 2397 patients were included. Combination therapy did not show a statistically significant improvement in PFS compared to PARP inhibitor monotherapy in the general population (HR 0.63, CI 0.37–1.06), or in BRCA-mutated (HR 0.70, CI 0.30–1.63) and BRCA wild-type subgroups (HR 0.39, CI 0.14–1.07). When compared to chemotherapy, combination therapy produced no significant PFS benefit in recurrent ovarian cancer (HR 0.83, CI 0.42–1.63) in the total population. Safety analysis revealed that hypertension and diarrhea were significantly more frequent in combination therapy compared with PARP inhibitors alone (RR 6.80, CI 2.87–16.06 and RR 10.04, CI 2.25–44.75) or chemotherapy alone (RR 13.80, CI 3.43–55.57 and RR 6.57, CI 2.84–15.24). Conclusions: The combination of PARP inhibitors and AAAs did not demonstrate a statistically significant benefit in PFS compared to PARP inhibitors or chemotherapy alone in recurrent ovarian cancer. While the combination therapy was generally well tolerated, hypertension and diarrhea occurred significantly. These findings suggest that combination therapy may not provide a clear survival advantage in the recurrent setting. Further high-quality, biomarker-driven clinical trials are needed to refine patient selection, optimize toxicity management, and determine the potential role of combination therapy in ovarian cancer treatment.

Introduction: Topical Imiquimod is an immune response modifier approved for the off-label use of vulvar intraepithelial neoplasia. We conducted this systematic review and meta-analysis to investigate the efficacy and safety of Imiquimod in treating cervical intraepithelial neoplasia (CIN) and human papillomavirus (HPV)-positive patients. Methods: The study was prospectively registered (CRD420222870) and involved a comprehensive systematic search of five medical databases on 10 October 2022. We included articles that assessed the use of Imiquimod in cervical dysplasia and HPV-positive patients. Pooled proportions, risk ratios (RRs), and corresponding 95% confidence intervals (CIs) were calculated using a random effects model to generate summary estimates. Statistical heterogeneity was assessed using I² tested by the Cochran Q tests. Results: Eight articles reported on 398 patients who received Imiquimod out of 672 patients. Among CIN-2–3 patients, we observed a pooled regression rate of 61% (CI: 0.46–0.75; I²: 77%). When compared, Imiquimod was inferior to conization (RR: 0.62; CI: 0.42–0.92; I²: 64%). The HPV clearance rate in women who completed Imiquimod treatment was 60% (CI: 0.31–0.81; I²: 57%). The majority of side effects reported were mild to moderate in severity. Conclusions: Our findings indicate that topical Imiquimod is safe and effective in reducing cervical intraepithelial neoplasia and promoting HPV clearance. However, it was found to be inferior compared to conization. Imiquimod could be considered a potential medication for high-grade CIN patients and should be incorporated into guidelines for treating cervical dysplasia.
