The placenta is a vital organ that supports fetal development by mediating nutrient and gas exchange, regulating immune tolerance, and maintaining hormonal balance. Its formation and function are tightly linked to the processes of embryo implantation and the establishment of a robust placental-uterine interface. Recent advances in molecular biology and histopathology have shed light on the key regulatory factors governing these processes, including trophoblast invasion, spiral artery remodeling, and the development of chorionic villi. This review integrates morphological and molecular perspectives on placental development, emphasizing the roles of cytokines, growth factors, and signaling pathways, such as VEGF and Notch signaling, in orchestrating implantation and placental formation. The intricate interplay between molecular regulation and morphological adaptations highlights the placenta’s critical role as a dynamic interface in pregnancy. This review synthesizes current findings to offer clinicians and researchers a comprehensive understanding of the placenta’s role in implantation, emphasizing its importance in maternal-fetal medicine. By integrating these insights, the review lays the groundwork for advancing diagnostic and therapeutic approaches that can enhance pregnancy outcomes and address related complications effectively.

Mindful eating may play an important role in long-term weight maintenance. In interventions aiming at weight reduction, increasing the levels of mindful eating was associated with higher levels of success and lower levels of weight rebound in the long run. This study aimed to determine the validity and reliability of a mindful eating questionnaire for Romanian adults using Framson’s Mindful Eating Questionnaire (MEQ). To calculate the internal (n = 495) and external (n = 45) reliability, a general population sample was taken. Construct validity was assessed using the “known groups” method: dietitians (n = 70), sports professionals (n = 52), and individuals with overweight and obesity (n = 200). Convergent validity tested the association between the MEQ score and demographic characteristics of the total sample (n = 617). The internal (0.72) and external (0.83) reliability were adequate. Dietitians and sports professionals had overall lower scores, meaning more mindful eating compared to the group of individuals with overweight and obesity. The lower mindful eating practice was associated with the presence of excess weight, suboptimal health status perception, higher levels of stress and younger age. The Romanian version of the MEQ is a reliable and valid tool for measuring mindfulness of eating in adults.

Background/Objectives: Cytokines play a fundamental role in the tumor microenvironment, influencing breast cancer progression, metastasis, and therapeutic resistance. The objective of this systematic review and meta-analysis was to evaluate the prognostic impact and therapeutic relevance of key cytokines in breast cancer, based on human studies published between 2015 and 2025. Methods: We systematically searched PubMed, Web of Science, and Scopus for eligible studies reporting on cytokine expression and clinical outcomes in breast cancer. Inclusion criteria were based on the PRISMA framework, focusing on human cohorts and excluding in vitro or animal models. Data were extracted on cytokine types, measurement methods, patient population, and outcomes. Meta-analyses were performed using random-effects models for cytokines with sufficient data, notably IL-6 and TNF-α. Results: Twenty-three studies were included. Elevated IL-6 was consistently associated with poor overall survival (pooled HR = 2.25, 95% CI 1.83–2.76), while high TNF-α levels showed a trend toward worse outcomes but without statistical significance. IL-1β, IL-8, and IL-10 were also linked to increased metastasis and reduced response to therapy. Immunosuppressive cytokines such as IL-10 and TGF-β facilitated tumor immune evasion, while IL-17 promoted inflammation and angiogenesis. Cytokines such as IL-12 and IFN-γ were associated with improved immune responses and a favorable prognosis. Conclusions: Cytokines are central mediators of breast cancer progression and immune regulation. Elevated levels of pro-inflammatory and immunosuppressive cytokines correlate with poor outcomes and may serve as prognostic biomarkers and therapeutic targets. Their integration into personalized treatment strategies holds significant clinical potential but requires further prospective validation and biomarker standardization.

Background: This study aimed to systematically review the existing literature on epithelioid trophoblastic tumors (ETTs), the rarest type of gestational trophoblastic neoplasia. Methods: A systematic review according to PRISMA guidelines was performed, using ScienceDirect, Web of Science, and Scopus databases. The only filter used was the English language. Eligibility/inclusion criteria: retrospective observational studies (case reports, case series) including full case description of epithelioid trophoblastic tumor lesions. Results: Seventy studies were assessed for synthesis, including 147 cases. 66.7% of patients with ETT presented with irregular vaginal bleeding. Pretreatment β-hCG levels ranged up to 1000 mIU/mL in 58.5% patients. Of most patients, 42.2% had stage I disease, 10.9% stage II, 25.2% stage III, and 21.8% of patients had stage IV. The most common sites of metastatic disease were the lungs, followed by the liver and brain. After treatment, complete remission was achieved in 75.5% of patients, partial remission in 10.2% of patients, and 14.3% of patients died. On univariate and multivariate analyses, stage IV disease was an independent prognostic factor for overall and disease-free survival. Conclusions: Hysterectomy and metastatic lesion resection are essential for controlling ETT. Investigational studies on molecules like EGFR, VEGF, PD-1, CD105, and LPCAT1 are potential therapeutic targets for metastatic ETT.

Academic stress and transitioning to young adulthood can lead medical students to develop inadequate eating habits, affecting both their physical and mental well-being and potentially compromising their ability to offer effective preventive counseling to future patients. The primary objective of this study is to analyze the levels of mindful eating and nutrition knowledge in Romanian medical students and their associations with various sociodemographic variables. Additionally, we explore the relationship between mindful eating and nutrition knowledge while accounting for sociodemographic factors and examine the impact of these factors on excess weight. Significant predictors of excess weight include high weight gain in the past year (OR = 15.8), the mindful eating questionnaire (MEQ) score (OR = 0.131), male gender (OR = 2.5), and being in the clinical years of medical school (OR = 2.2). While nutrition knowledge levels do not directly impact weight status, they share a 4% common variance with mindfulness in multivariate analysis. Notably, high weight gain is independent of the levels of mindful eating, but univariate testing links it to disinhibition and emotional response, components of mindfulness. Mindful eating stands out as independently associated with both nutrition knowledge and excess weight among medical students. Thus, interventions to address obesity should consider incorporating mindfulness training to enhance food intake awareness and improve weight management outcomes in Romanian medical students.

Background/Objectives: Breast cancer remains a leading cause of cancer-related morbidity worldwide, and refining prognostic tools is essential for individualized patient management. Recent evidence suggests that the systemic immune–inflammation index (SII), derived from routine blood tests, may offer valuable prognostic insights. This study aimed to evaluate whether SII can reliably predict clinical outcomes for patients undergoing curative resection. Methods: We retrospectively analyzed patients with histologically confirmed breast cancer who underwent surgical intervention at a single tertiary center. Preoperative complete blood counts were used to calculate SII. Using receiver operating characteristic (ROC) curve analysis, we identified an optimal SII cutoff. Using statistical tests, including t-tests and ANOVA, we examined differences in clinicopathological factors between low- and high-SII groups. Using univariate and multivariate analyses, we explored associations between SII and variables such as tumor stage and hormone receptor status. Results: Patients with elevated SII levels showed significant associations with more advanced tumor stage and systemic inflammatory profiles. The identified SII cutoff separated patients into distinct risk groups, and high SII values correlated with poorer prognostic features. Multivariate models indicated that SII provided additional predictive value beyond standard markers. Conclusions: Our findings suggest that SII may provide prognostic insights into breast cancer, particularly in stratifying patients based on inflammatory profiles. However, the current study does not support the use of SII as a clinical tool for tailoring treatment strategies. Further preclinical and randomized controlled trials are required to determine its predictive utility and to assess its potential integration into personalized management approaches.
