Hop plant (Humulus lupulus L.) has been used by humans for ages, presumably first as a herbal remedy, then in the manufacturing of different products, from which beer is the most largely consumed. Female hops cones have different useful chemical compounds, an important class being antioxidants, mainly polyphenols. This narrative review describes the main antioxidants in hops, their bioavailability and biological effects, and the results obtained by now in the primary and secondary prevention of several non-communicable diseases, such as the metabolic syndrome related diseases and oncology. This article presents in vitro and in vivo data in order to better understand what was accomplished in terms of knowledge and practice, and what needs to be clarified by additional studies, mainly regarding xantohumol and its derivates, as well as regarding the bitter acids of hops. The multiple protective effects found by different studies are hindered up to now by the low bioavailability of some of the main antioxidants in hops. However, there are new promising products with important health effects and perspectives of use as food supplements, in a market where consumers increasingly search for products originating directly from plants.

Overall, it is estimated that more than 3,500,000 patients have received Bevacizumab as part of systemic oncologic treatment. Bevacizumab and its biosimilars are currently marketed in over 130 countries. Given the wide usage of Bevacizumab in current oncological practice, it is very important to compare the “real-world” results to those obtained in controlled clinical trials. This study aims to describe the clinical experience of using Bevacizumab in a large cohort of cancer patients in “non-controlled real-world” conditions with regard to effectiveness, safety, and cost of therapy. Methods: For this purpose, we conducted an open, observational, retrospective study involving all patients treated for solid malignant tumors in the Bucharest Institute of Oncology with “Prof. Dr. Al. Trestioreanu” with Bevacizumab-based systemic therapy, between 2017 and 2021. Results: The study consisted of 657 treatment episodes in 625 patients (F/B = 1.62/1, with a median age of 57.6 years) which were treated for malignant tumors (majority colorectal, non-small cell lung, ovarian, and breast cancer). First-line treatment was administered in 229 patients, and the rest received Bevacizumab as second or subsequent lines of treatment. The overall response rate to Bevacizumab-based therapies was around 60–65% across all indication except for subsequent treatment lines in colorectal and ovarian cancers, where lower values were recorded (27.1%, and 31.5% respectively). Median PFS for the entire cohort was 8.2 months (95% CI 6.8–9.6), and the median OS was 13.2 months (95% CI 11.5–14.9). Usual bevacizumab-related toxicities were observed, including bleeding, hypertension, wound-healing complications, gastrointestinal perforation, other types of fistulas, septic complications, and thromboembolic events. Although the clinical benefits are undeniable, the addition of Bevacizumab to standard chemotherapy increased the overall treatment cost by 213%. Conclusions: Bevacizumab remains a high-cost therapy, but it can add to clinical benefits (like overall survival, progression-free survival, and response rate) when used in conjunction with standard chemotherapy. Similar results as those presented in various controlled trials are observable even on unselected cohorts of patients in the uncontrolled conditions of “real-world” oncological practice. Off-label usage is encountered in clinical practice, and this aspect should be monitored given the potential adverse effects of the therapy.

(1) Background: Gestational diabetes mellitus (GDM) is a glucose metabolism disorder that typically develops in the second half of pregnancy, transforming a normal pregnancy into a high-risk condition, with both short- and long-term complications for the mother and the fetus. Achieving optimal glycaemic control during pregnancy is essential for preventing these outcomes and could be realized using continuous glucose monitoring systems (CGMSs). This systematic review aims to evaluate the role of the CGMS as a potential diagnostic aid and predictor of maternal and fetal outcomes in GDM. (2) Methods: Following the PRISMA guidelines (protocol ID: CRD42024559169), we performed a literature search using the terms “(continuous glucose monitoring system OR CGMS) AND (gestational diabetes mellitus OR GDM)” in the PubMed, Web of Science, and Scopus databases. (3) Results: Twelve studies were included, all reporting data on CGMS use in pregnancies complicated by GDM. The data included in our analysis are heterogeneous, the results suggesting that the CGMS may offer several advantages such as improved glycaemic control (by avoiding hyper- and hypoglycaemia), better gestational weight management, timely initiation of pharmacologic treatment, lower rates of preeclampsia, and improved neonatal outcomes. (4) Conclusions: the CGMS offers a more detailed assessment of both maternal and fetal exposure to high glucose levels, which could lead to earlier detection of those at risk for GDM complications and better guide treatment regimens, especially timely pharmacological intervention. While the current data are heterogeneous, reporting both limited or no benefits and superior benefits compared to the classic monitoring, larger longitudinal studies are mandatory to validate these findings and to better refine the role of CGMS in the monitoring and management of GDM.

Background: Cesarean deliveries have increased in recent years worldwide. This increase translates into an escalation of obstetrical complications that could lead to permanent injuries. Comprehensive knowledge of the risk factors for uterine scar defects and their probability factor could guide gynecologists towards decreasing the percentage of scar defects and reducing the morbidity produced by a scarred uterus. Methods: A review of the literature published in the last 10 years produced a number of 80,085 articles, from which we screened 147 articles and selected 11 recently published papers, attempting to rank the most frequently described risk factors in terms of probability. A total number of 11,349 patients who underwent CS were included from the 11 studies. Results: Cesarean scar defects developed in 19.42% of cases; our results showed that the highest probability was given by single-layer suture, with gestational diabetes being the main patient-related risk factor for scar defects. A definitive ranking of the risks is difficult to assess, because different studies focus on certain risks and most of the relevant data are missing or are omitted. Conclusions: In this study, we investigate the most common risk factors that give rise to the development of cesarian scar defects, conducting a ranking of these risks from the most probable to the least important, in order to facilitate informed decision making for providers.

Lynch syndrome, one of the most common genetic syndromes predisposing to cancer, is associated with a series of malignant conditions, among which the most frequent is colorectal cancer, but gynecologic cancers (especially endometrial) are also quite common. Despite the significant progress made in understanding this condition over time, there are still aspects in managing this condition that have not demonstrated clear benefits. This article aims to summarize the recommendations of international societies and present the latest developments in managing Lynch syndrome, focusing on gynecologic cancer screening and possible prevention strategies. Advances in genetic testing procedures and discoveries related to the association between oncological pathology frequency and the affected pathogenic variant type will probably lead to personalized medicine focused on the individual patient in the coming years. Although various screening methods for gynecological cancers in patients with Lynch syndrome have been used over time, they have not shown significant survival benefits. This highlights the need for studying and implementing new screening and diagnostic methods, which have been under investigation in recent years and are mentioned in this article.

Background: Gestational diabetes mellitus (GDM) represents a pregnancy-specific associated pathology that bears a heavy burden on patients and also on the healthcare system. GDM displays an increasing incidence and short- and long-term materno-fetal consequences. Its prevention strategies include lifestyle interventions, diet changes, gestational weight gain control, moderate-intensity exercise, and smoking cessation. GDM screening is performed in the second half of pregnancy between 24 and 28 gestational weeks. Treatment options include medical nutrition therapy and pharmacologic therapy. In most cases, optimum glycemic control is obtained by medical nutrition therapy alone. Although there are screening and treatment options, the medical system in Romania lacks homogeneity in the diagnosis and further management of pregnancies complicated with GDM. There is an urgent need to improve the healthcare system and the basic medical knowledge of the population and to find efficient strategies, which include a national diabetes in pregnancy guideline to ensure pregnancy monitoring, GDM screening, and the diagnosis and personalized management of cases in order to promote good pregnancy outcomes and minimize adverse pregnancy events.
