Abstract
Uterine fibroids (UFs) are the most common benign tumors in women of reproductive age, frequently associated with pain symptoms and heavy menstrual bleeding (HMB), leading to impaired quality of life. Thus, the aim of the study was to evaluate the global perception of stress and the menstrual distress in patients with UFs. A cross-sectional observational study was conducted on a group (n = 69) of fertile age women with UFs compared to age-matched controls, by administering two questionnaires: the perceived stress scale (PSS) and the Menstrual Distress Questionnaire (MEDI-Q). The PSS, MEDI-Q Total Score and 3 subscales—menstrual symptoms (MS), menstrual symptoms distress (MSD), and menstrual specificity index (MESI)—were evaluated. Patients with UFs showed higher PSS than controls (18.5 ± 5.0 vs. 13.8 ± 5.0, p < 0.001) and PSS values were very high in those with HMB, severe dysmenorrhea, and impaired social and working life. Patients with UFs also showed significantly higher score for MEDI-Q Total Score (16.51 ± 12.99 vs. 10.86 ± 12.36) (p < 0.01) as well as for the subscales MSD (2.54 ± 1.07 vs. 1.57 ± 0.98) (p < 0.001) and MESI (0.76 ± 0.30 vs 0.60 ± 0.39) (p < 0.05). The menstrual distress was associated to being uncomfortable about uterine bleeding; in fact, MEDI-Q Total Score was significantly higher in women with HMB compared to those with moderate/normal bleeding. UF characteristics (number, type, and size) did not correlate with perceived stress or menstrual distress. In conclusion, women with UFs have significantly higher levels of perceived stress and menstrual distress than controls and HMB plays a major role in determining such conditions.

Abstract
Endometriosis is a chronic inflammatory condition affecting women of reproductive age. A relevant feature of endometriosis is the presence of fibrotic tissue inside and around the lesions, thus contributing to the classic endometriosis-related symptoms, pain, and infertility. The molecular mechanisms responsible for the development of fibrosis in endometriosis are not yet defined. The present review aimed to examine the biological mechanisms and signalling pathways involved in fibrogenesis of endometriotic lesions, highlighting the difference between deep infiltrating and ovarian endometriosis. The main cell types involved in the development of fibrosis are platelets, myofibroblasts, macrophages, and sensory nerve fibers. Members of the transforming growth factor (TGF) -β family, as well as the receptor Notch, or the bioactive sphingolipid sphingosine 1-phosphate (S1P), play a role in the development of tissue fibrosis, resulting in their metabolism and/or their signalling pathways altered in endometriotic lesions. It is relevant the knowledge of the molecular mechanisms that guide and support fibrosis in endometriosis, to identify new drug targets and provide new therapeutic approaches to patients.
