RESUMEN

Background: This study aimed to systematically review the existing literature on uterine smooth muscle tumor of uncertain malignant potential (STUMP) to provide information about characteristics and outcomes of patients and the risk factors for recurrence over a period of 60 years (1960−2021). Methods: According to PRISMA guidelines, we searched for "uterine smooth muscle tumor of uncertain malignant potential" in PubMed (all fields) and Scopus (Title/Abstract/Keywords) databases (accessed on 1 January 2022). Relevant articles were obtained in full-text format and screened for additional references. The only filter used was the English language. Studies including full case description of patients with histopathological diagnosis of STUMP in accordance with Stanford criteria were included. Results: Thirty-four studies, including 189 cases, were included. The median age was 43 years, and in 21.5% of cases there was a recurrence of the disease. Bivariate analysis showed a significant association between use of morcellation without bag and risk of recurrence (p = 0.001). Unprotected morcellation during demolitive or conservative surgery was independently associated with a higher risk of disease recurrence with a relative risk of 2.94 (p < 0.001). A significant progressive decrease in the recurrence rate was observed over time (r = −0.671, p = 0.008). The percentage of patients who underwent surgery followed by in-bag protected morcellation significantly increased after the publication of the U.S. Food and Drug Administration alert about the risk linked to this procedure (p = 0.01). Conclusions: Unprotected morcellation of the lesion is associated with the relapse of the disease. However, this clinical condition showed a drastic decrease over time. This could likely be due to the increased awareness by surgeons of the importance of customizing surgical treatment.

RESUMEN

Uterine fibroids are the most common cause of solid pelvic tumours, occurring in 20-30% of fertile women and presenting clinical complications that seriously affect women's health. They commonly cause severe symptoms, such as heavy, prolonged menstrual bleeding and anaemia. The study of microscopic and macroscopic vascular aspects of uterine fibroids is important for understanding the clinical manifestations of uterine fibroids, for predicting the effectiveness of alternative treatments to surgery, i.e. uterine artery embolization, for improving surgery outcomes and for carrying out a differential diagnosis with other benign conditions, e.g. adenomyosis, or malignancy, e.g. leiomyosarcoma, and to develop new therapeutic approaches. In this review, current knowledge of how the vascular network and angiogenesis are implied in the formation of uterine fibroids and in the pathogenesis of related symptoms is explored, and evidence on the role of ultrasound in evaluating fibroid vascularization is summarized. This review combines anatomical, morphological and biomolecular information related to angiogenic mechanisms with diagnostic and clinical information, highlighting the various interconnections. Uterine and fibroid vascularization need further investigation to gain a deeper understanding of the pathogenetic elements that lead to the formation of uterine fibroids and their clinical manifestations.

RESUMEN

Objective: This study aimed to systematically review the existing literature on malignant transformation of postmenopausal endometriosis to provide information about patient characteristics, hormonal replacement therapy (HRT) use, and outcomes over a period of 52 years (1969-2021). Methods: According to PRISMA guidelines, we searched for (endometriosis OR endometriotic) AND (cancer OR malignancy OR malignant transformation) AND (menopause OR menopausal OR postmenopause OR postmenopausal) in Pubmed (all fields) (accessed on 12 February 2021) and Scopus (Title/Abstract/Keywords) (accessed on 12 February 2021) databases. The only filter used was the English language. Relevant articles were obtained in full-text format and screened for additional references. Eligibility/inclusion criteria: studies including full case description of malignant transformation of endometriosis-related lesions in postmenopause. Results: 75 studies, including 90 cases, were retrieved. The mean age was 55.8 ± 8.5 years. Overall, about 65% of women had a positive personal history of endometriosis/adenomyosis, and 64% of women underwent previous hysterectomy ± bilateral salpingo-oophorectomy. Forty-nine of 74 women used HRT (66.2%). Among the women who used HRT, estrogen-only treatment was taken by approximately 75%. Duration of HRT was longer than five years in 63.3% of cases. About 70% of subjects had histology of endometrioid adenocarcinoma or clear cell carcinoma. Follow-up outcome, available for 61 women, showed a survival rate of 78.7%, recurrence of 9.8%, death of 11.5%. The duration of follow-up had a median of 12 months (interquartile range, 6.75-25 months). Interestingly, over the years of case publication there was a significant inverse correlation with previous history of endometriosis (r = -0.28, p = 0.007), HRT use (r = -0.31, p = 0.006), and previous definitive surgery (r = -0.42, p < 0.001). Conclusions: In the malignant transformation of postmenopausal endometriosis, there are some recurrent clinical conditions: previous endometriosis, major definitive surgery before menopause, and estrogen-only HRT for a relatively long time. However, these clinical conditions have shown a drastic decrease over time. This could likely be the consequence of different attitudes and management of gynecologists linked to up-to-date scientific evidence about the use of major surgery in gynecological pathologies. Malignant transformation of postmenopausal endometriosis is a clinical challenge to be explored further.

RESUMEN

AIM: The aim of this study was to examine the psychometric properties of a prosociality scale within the palliative nursing context, and then examine the impact of prosocial behaviour in relation to job and educational satisfaction among palliative nurses. METHODS: An online cross-sectional survey was conducted in 25 Italian palliative care centres, with a total of 107 nurses completing the prosociality scale by Caprara et al (2005) . Exploratory and confirmatory factor analyses were examined to evaluate a multidimensional model of prosociality. RESULTS: A three-factor solution with a second order factor fitted the data well. The three dimensions extracted were labelled as helping, empathy, and sharing. Participants reported high levels of prosociality. In addition, prosociality was positively associated with job and educational satisfaction. CONCLUSIONS: The prosociality scale was valid and reliable when tested with palliative nurses. Although prosociality may be embedded in nurses' personalities, this quality should be actively promoted to expand and improve the culture and the ethics of nursing.

RESUMEN

Following up previous experience with External Quality Assessment (EQA) and Proficiency Testing Programs (PTP) on drugs of abuse (DoA) testing in Italy and in other European countries, the government of the Lombardy Region, first among Italian regions, established in 1995 a compulsory EQA scheme for laboratories authorized to perform these tests. The purpose of the present work is the description of the program and the overall evaluation of the results obtained in the first three annual cycles (1995-1998). During each annual cycle laboratories received 22 urine samples; some samples were collected from patients ("real samples") and some were "spiked" urine samples. Both types of samples could contain the following substances/classes of substances: opiates, cocaine, cannabinoids, methadone, buprenorphine, benzodiazepines, barbiturates. Type A laboratories used an immunological screening method; they expressed the results as concentrations. Type B laboratories, authorized to perform screening methods followed by confirmatory techniques, searched for and identified single substances and provided an interpretation on possibly taken drugs. During the study period the laboratories produced about 21,000 analytical results. Among them, false-negative results were 0.9% of true positives, and false-positive results were 0.7% of true negatives. Performance using the spiked samples was better than using real samples, and performance of type B laboratories better than that of type A. The results obtained during the program are consistent with those of other quality control programs. This program, in addition, has provided information on the status of DoA testing in the Lombardy region's laboratories, in particular on their analytical performance, on the quality of interpretation of results and on a degree of improvement achieved during the program.
