The interplay between gut microbiota and retinal health, known as the gut-–retina axis, has gained increasing attention in recent years. Short-chain fatty acids (SCFAs), metabolites produced by gut microbiota, have been identified as key mediators of gut–retina communication. This systematic review explores the role of SCFAs in retinal health and their potential impact on the development and progression of retinal diseases, such as diabetic retinopathy (DR), age-related macular degeneration (AMD), and glaucoma. A literature search was conducted across multiple databases, including PubMed, Google Scholar, and Science Direct, to identify studies published between 2014 and December 2024. Studies were included if they investigated the effects of SCFAs on retinal structure, function, or disease pathogenesis in animal models or human subjects. The review included 10 original articles spanning both preclinical and clinical studies. Evidence suggests that SCFAs play a crucial role in maintaining retinal homeostasis through anti-inflammatory and neuroprotective mechanisms. Dysbiosis of the gut microbiota, leading to altered SCFA production, was associated with increased retinal inflammation, oxidative stress, and vascular dysfunction. Furthermore, reduced SCFA levels were linked to the progression of retinal diseases, such as diabetic retinopathy and age-related macular degeneration. Modulation of gut microbiota and SCFA levels through dietary interventions or probiotics may represent a novel therapeutic strategy for preventing or managing retinal diseases. Further research is needed to elucidate the precise molecular mechanisms underlying SCFA-mediated retinal protection and to evaluate the efficacy of targeted therapies in clinical settings.

Background: Vitamin D deficiency is increasingly recognized as a global health concern, with potential implications for cancer development and progression. This systematic review investigated the prevalence of vitamin D deficiency in pediatric cancer patients and its potential impact on clinical outcomes. Methods: A comprehensive literature search was conducted across multiple databases, including PubMed, Web of Science, and Cochrane Library, to identify the relevant studies published between 2009 and July 2024. Studies were included if they assessed vitamin D status in pediatric cancer patients and reported on the clinical outcomes. Data extraction and quality assessment were performed independently by two reviewers. Results: The review included 20 original articles encompassing a diverse pediatric population with various cancer types. A high prevalence of vitamin D deficiency was observed across the studies. Deficiency was associated with older age and lower socioeconomic status. Several studies reported associations between vitamin D deficiency and the increased risk of infection, poorer treatment response, and decreased survival. Conclusions: Vitamin D deficiency is highly prevalent in pediatric cancer patients and may negatively impact clinical outcomes. Routine screening for vitamin D deficiency and personalized supplementation strategies should be considered in this population. Further research is needed to establish optimal vitamin D management protocols and evaluate the long-term benefits of vitamin D repletion in pediatric oncology.

Study objective: The objective of this systematic review is to investigate the impact of laparoscopic myomectomy techniques on pregnancy outcomes, with a specific focus on the correlation between the type of suture used during the procedure and the incidence of uterine rupture. Additionally, the study aims to examine how the localization and size of myomas, key factors in laparoscopic myomectomy, may influence fertility outcomes. Data Sources: extensive searches were conducted using MDPI, PubMed, Web of Science, and Cochrane Library databases from 2008 to November 2023. Methods of Study Selection: The study involved women of reproductive age diagnosed with fibroids who underwent surgical removal of fibroids using either laparotomy or laparoscopy. The evaluation of pregnancy outcomes focused on indicators such as live birth rates, miscarriage rates, stillbirth rates, premature delivery rates, and cases of uterine rupture. Quality assessment was systematically performed by employing the National Institutes of Health Study Quality Assessment Tools, with the subsequent formulation of clinical recommendations that were meticulously graded in accordance with the robustness of the underlying evidence. Results: The pregnancy outcomes post-myoma treatment, as reflected in one of the presented tables, show a promising number of pregnancies and live births, but also indicate the potential risks of miscarriages and preterm births. The diversity in outcomes observed among various studies underscores the imperative for tailored patient care, as well as the necessity for additional research aimed at optimizing fertility and pregnancy outcomes following myoma treatment. Conclusion: This study offers insights into the criteria for patient selection and intraoperative methodologies specifically related to laparoscopic myomectomy. To enhance our understanding of the associations between fibroid characteristics (location, size) and reproductive outcomes, additional research is warranted, particularly through well-designed clinical trials.

Background/Objectives: Immune checkpoint inhibitors targeting the PD-1/PD-L1 axis have become a standard in the treatment of all stages of non-small lung cancer. Beyond tumor-intrinsic biomarkers like PD-L1 expression, evidence points to the role of patient-related factors, such as body mass index, sarcopenia, and cachexia. These body composition parameters may reflect metabolic reserve or even immune competence and could help stratify outcomes in patients treated with PD-1 and PD-L1. This systematic review aims to evaluate the impact of body composition—specifically BMI, pretreatment weight loss, sarcopenia, and cachexia—on clinical outcomes such as progression-free and overall survival in NSCLC patients treated with immune checkpoint inhibitors. Methods: A systematic literature search was conducted across multiple databases including PubMed, Google Scholar, and Science Direct. We included full-text original research articles (1 January 2020–1 May 2025) reporting clinical outcomes of NSCLC patients treated with PD-1 or PD-L1 inhibitors, in relation to body composition factors (BMI, pretreatment weight loss, sarcopenia, cachexia). Eligible studies involved adults (>18 years) and included observational cohorts or controlled trials; animal or in vitro studies were excluded. Data extraction and risk of bias assessments were performed independently by two reviewers, with discrepancies being resolved through a third one. Results: From 12,358 records identified, 21 studies met the inclusion criteria. Most were retrospective cohorts assessing the impact of pre-treatment weight loss, cachexia, and sarcopenia on ICI outcomes in NSCLC. These factors consistently predicted poorer survival and response, while BMI alone showed limited prognostic value. Considerable heterogeneity in body composition definitions and outcome reporting was observed. Conclusions: Body composition—particularly weight loss, cachexia, and sarcopenia—significantly impacts survival and response in NSCLC patients treated with ICIs. These factors reflect immune–metabolic dysfunction that may impair treatment efficacy. BMI alone is insufficient; routine assessment of muscle mass and cachexia could improve risk stratification.

Background: Oral mucositis (OM) is a frequent complication of anticancer therapy which arises from cytotoxic injury, having significant clinical implications. Nutritional and supplement-based interventions have been proposed as adjunctive strategies to improve outcomes. Objectives: This systematic review aimed to identify and synthesize evidence from randomized controlled trials (RCTs) evaluating nutritional or natural supplement interventions for prevention or management of OM in pediatric oncology. Methods: We conducted a systematic search (17 August 2025) of Scopus, PubMed/MEDLINE, and Google Scholar (1 January 2000–1 June 2025) following PRISMA guidelines and registered in PROSPERO (CRD420251134454). The review included randomized controlled trials in pediatric cancer patients (≤18 years; up to 25 years for follow-up) receiving chemo-/radiotherapy, assessing nutritional, dietary, or natural product interventions for oral mucositis prevention or treatment. Non-randomized, adult, non-English, non-peer-reviewed, or inaccessible studies were excluded. Outcomes included incidence, severity, duration of OM, and mucositis-associated pain. Risk of bias was assessed using the NIH Study Quality Assessment Tools and the Cochrane RoB 2 tool. Results were qualitatively summarized. Results: Of 5870 records identified, 20 RCTs met inclusion criteria resulting in 1430 total included patients. Interventions tested included systemic supplements (e.g., glutamine, zinc, and bovine colostrum), topically applied agents (e.g., honey, vitamin E, Aloe vera, and olive oil), and nutrient-containing rinses (e.g., chamomile, Caphosol, and Traumeel S). Honey-based interventions showed promising outcomes. Discussion: Study designs and sample sizes varied considerably, and outcome measures were heterogeneous. Challenges with blinding, variable compliance, and inconsistent reporting reduce confidence and precision in the findings. Conclusions: Evidence from pediatric RCTs remains limited but highlights nutritional and natural products as promising supportive care options for OM. Findings suggest potential for practical, low-cost adjuncts to established oral care protocols, warranting further high-quality multicenter trials.

Objective: This study aims to provide an in-depth analysis of patient preferences and clinical outcomes associated with two surgical techniques for treating stress urinary incontinence (SUI): the transobturator suburethral sling (TOT) procedure and the pubourethral ligament plication (PUL) procedure. We evaluated the rates of postoperative complications, the duration of each procedure, hemoglobin loss, and days of hospitalization. Materials and Methods: This prospective study included 80 patients who underwent surgery for SUI: 40 patients for the TOT procedure and 40 patients for the PUL procedure. Clinical data on patient characteristics, treatment efficacy, and post-surgical outcomes were analyzed to assess patient preferences and real-world clinical effectiveness. Results: Regarding patient preferences, those who underwent TOT surgery were more likely to be older, had a higher average number of pregnancies, and were more often postmenopausal, in contrast to those who underwent PUL surgery (p < 0.001 for each comparison). TOT patients had a hospital stay on average of 1.02 days, while PUL patients benefited from ambulatory stays only. In addition, the TOT group had a significantly longer average operating time (16.80 min) compared to the PUL group (9.90 min, p < 0.001). The study revealed notable outcomes in both groups, with high cure rates for both TOT (N₁ = 33, 82.5%) and PUL (N₂ = 28, 70%) procedures. Specifically, 76.25% of the patients (61 out of 80) were cured after the procedures. Chronic pelvic pain was present in 3.75% of all patients and was notably only observed in the TOT group, with 3 (7.5%) cases being noted. Similarly, vaginal erosion was experienced by 5% of all patients, with 10% of patients in the TOT group and none in the PUL group being affected. Dyspareunia occurred in 2.5% of all patients, with there being two (5%) cases in the TOT group and none in the PUL group. Conclusions: This study highlights that while the PUL procedure achieves cure rates comparable to TOT, it offers a less invasive option with shorter operating times and no hospitalization required. These findings suggest that PUL could be a viable alternative for stress urinary incontinence (SUI) treatment, especially in contexts where avoiding mesh use is preferred. This adds significant value to patient-centered care in SUI management, offering tailored treatment options based on patient characteristics, preferences, and risk profiles.
