RESUMO

Childhood cancer incidence, especially in high-income countries, has led to a focus on preserving fertility in this vulnerable population. The common treatments, such as radiation and certain chemotherapeutic agents, though effective, pose a risk to fertility. For adult women, established techniques like embryo and egg freezing are standard, requiring ovarian stimulation. However, for prepubescent girls, ovarian tissue freezing has become the primary option, eliminating the need for hormonal preparation. This review describes the beginning, evolution, and current situation of the fertility preservation options for this young population. A total of 75 studies were included, covering the steps in the current fertility preservation protocols: (i) ovarian tissue extraction, (ii) the freezing method, and (iii) thawing and transplantation. Cryopreservation and the subsequent transplantation of ovarian tissue have resulted in successful fertility restoration, with over 200 recorded live births, including cases involving ovarian tissue cryopreserved from prepubescent girls. Despite promising results, challenges persist, such as follicular loss during transplantation, which is attributed to ischemic and oxidative damage. Optimizing ovarian tissue-freezing processes and exploring alternatives to transplantation, like in vitro systems for follicles to establish maturation, are essential to mitigating associated risks. Further research is required in fertility preservation techniques to enhance clinical outcomes in the future. Ovarian tissue cryopreservation appears to be a method with specific benefits, indications, and risks, which can be an important tool in terms of preserving fertility in younger women.

RESUMO

OBJECTIVE: Uterine sarcomas are a rare and heterogeneous group of malignancies that include different histological sub-types. The aim of this study was to identify and evaluate the impact of the different prognostic factors on overall survival and disease-free survival of patients with uterine sarcoma. METHODS: This international multicenter retrospective study included 683 patients diagnosed with uterine sarcoma at 46 different institutions between January 2001 and December 2007. RESULTS: The 5-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma, and adenosarcoma was 65.3%, 78.3%, 52.4%, and 89.5%, respectively, and the 5-year disease-free survival was 54.3%, 68.1%, 40.3%, and 85.3%, respectively. The 10-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma and adenosarcoma was 52.6%, 64.8%, 52.4%, and 79.5%, respectively, and the 10-year disease-free survival was 44.7%, 53.3%, 40.3%, and 77.5%, respectively. The most significant factor associated with overall survival in all types of sarcoma except for adenosarcoma was the presence of residual disease after primary treatment. In adenosarcoma, disease stage at diagnosis was the most important factor (hazard ratio 17.7; 95% CI 2.86 to 109.93). CONCLUSION: Incomplete cytoreduction, tumor persistence, advanced stage, extra-uterine and tumor margin involvement, and the presence of necrosis were relevant prognostic factors significantly affecting overall survival in uterine sarcoma. The presence of lymph vascular space involvement and administration of adjuvant chemotherapy were significantly associated with a higher risk of relapse.

RESUMO

OBJECTIVES: The objective is to assess the perception of gynecologists regarding patients' adherence to vulvovaginal atrophy (VVA) treatments, to evaluate the gynecologists' opinions on what their patients think about treatment adherence, and to compare the gynecologists' opinions with the patients' own perceptions within the CRETA study. METHODS: Spanish gynecologists who participated in the CRETA study were asked to fill out an online 41-item questionnaire to evaluate their views on VVA management. RESULTS: From 29 centers across Spain, 44 gynecologists completed the survey. Their mean age was 47.2 years old, two-thirds of them were women, and the average professional experience was over 20 years. According to the gynecologists, the therapy most frequently used by VVA-diagnosed women was vaginal moisturizers (45.5%), followed by local estrogen therapy (36.4%) and ospemifene (18.2%). Nevertheless, ospemifene was viewed as the therapeutic option with the most efficacy, easiest route of administration, shorter time to symptom improvement, lower percentage of dropouts, and higher treatment adherence. CONCLUSIONS: Spanish gynecologists are in general agreement with their patients regarding VVA treatment preferences and the main issues for adherence and effectiveness. However, there is an opportunity for doctor-patient communication improvement. Among the three therapeutic options evaluated, ospemifene is regarded as offering some competitive advantages.

RESUMO

Background: Relieving vulvar pain caused by atrophy in postmenopausal women is a challenge in our clinical practice. We know more and more about the vulva, its anatomy and physiology and we are realizing that it is different from the vagina. The importance of the vulvar approach in the management of vulvar or vestibular pain (VP) due to atrophy in postmenopausal women is becoming increasingly important. A panel of experts from several Spanish scientific societies (Spanish Menopause Society, AEEM; Spanish Federation of Sexology Societies, FESS; Spanish Society of Primary Care Physicians, SEMERGEN; and the Spanish Society of Gynecology and Obstetrics) held a meeting to discuss treatment recommendations for women with vulvar and VP based on the best available evidence, creating a report to describe grades of recommendations.

RESUMO

The aim of the study was to evaluate the level of knowledge that women have about menopause and to analyse whether sociodemographic aspects can influence it. For this, a multi-centre observational study was conducted in Spain using a survey including 2500 women between 35 and 75 years. Participants were administered a 10-question questionnaire with a maximum score of 45 points. The responses of 2355 women were analysed. The median age was 52 years (IQR 45-59) and the median of knowledge score was 22 points (IQR 16-27). Age (p < .001), menopausal status (p = .030), early menopause (p = .001), educational level (p < .001), type of healthcare (p < .001) and sources of information on menopause (p < .001) were factors related to the score on the questionnaire. We conclude that Spanish women have limited knowledge about menopause and it is urgent to implement training programs that can improve it.IMPACT STATEMENTWhat is already known on this subject? The knowledge and attitudes about menopause among women can vary across countries and also according to sociocultural context. It also seems that negative attitudes towards menopause and poor knowledge of the physiology and the most frequent symptoms have an increasing effect on the severity of the specific symptoms of menopause that cause further discomfort.What do the results of this study add? There are very few available reports or research on the issue of postmenopausal health in Spain. We believe that it is appropriate to explore the level of knowledge of women in our country. We have verified that the level of knowledge of Spanish women is low and that some sociodemographic aspects can influence itWhat are the implications of these findings for clinical practice and/or further research? Taking into account our results, it is a priority to implement health training programs to improve knowledge about menopause in Spanish women and overcome false myths and wrong beliefs.

RESUMO

OBJECTIVE: Risk models in endometrial cancer define prognosis and indicate adjuvant therapy. One of the currently used classifications was designed in 2016 in collaboration with the European Society of Medical Oncology (ESMO), the European Society of Gynecologic Oncology (ESGO), and the European Society of Radiotherapy (ESTRO). A high-intermediate risk group was introduced within the intermediate risk group. The purpose of this study was to evaluate the clinical relevance of this subclassification. METHODS: A multicenter retrospective study was carried out at five international tertiary institutions. Patients diagnosed with intermediate risk endometrial cancer on the basis of definitive pathology findings were included. Patients were stratified into intermediate and high-intermediate risk groups. Incidence of nodal metastases, and disease free and overall survival were compared between the two risk groups in univariate and multivariate analysis. RESULTS: 477 patients were included: 325 (68%) patients were identified as intermediate and 152 (32%) as high-intermediate endometrial cancer patients. Nodal metastases were found in 18 patients (11.8%) in the high-intermediate risk endometrial cancer group and 16 patients (4.9%) in the intermediate risk group. Lymphovascular space invasion was found to be a strong predictive factor of lymph node involvement. High-intermediate risk was found to be an independent factor of disease free survival (hazard ratio (HR) 1.76; 95% confidence interval (CI) 1.00 to 3.08; p=0.050) and overall survival (HR 1.99; 95% CI 1.10 to 3.60; p=0.022) in the multivariate analysis. CONCLUSIONS: The study validates the clinical significance of the intermediate risk endometrial cancer subclassification. Prognosis for high-intermediate risk endometrial cancer was significantly poorer. The prevalence of lymph node metastases was higher in this group of patients.

RESUMO

OBJECTIVE: To study what women think about menopause treatments and assess their knowledge about them. To analyze adherence to treatment during COVID-19 confinement as a secondary objective. METHODS: A multi-center cross-sectional observational study was conducted using a survey of 2500 women between January and June 2019. This was administered following a non-probability sampling procedure including women between 35 and 75 years. An extension study was conducted during the coronavirus pandemic, between March and June 2020. RESULTS: The responses of 2355 surveyed women were analyzed. Of this sample, 42% knew about menopause hormone therapy (MHT). The most frequently identified indication was the treatment of hot flashes (65.6%). The MHT risks most frequently perceived were weight gain (24.2%) and breast cancer (21.7%); the main reason for rejecting MHT was a lack of information (96.1%). Comparative analyses were conducted according to age, menopausal status, type of menopause, place of residence, type of health care and level of education. During the coronavirus confinement period, 85 women using MHT were located, of which 84.7% continued it. CONCLUSIONS: Women hold certain false beliefs about menopause, and their knowledge of the available treatments is somewhat limited. Adherence to MHT during the COVID-19 confinement in Spain has been high.

RESUMO

In the Peruvian Amazon, paca meat is consumed by humans. To determine human risk for polycystic echinococcosis, we examined wild pacas from 2 villages; 15 (11.7%) of 128 were infected with Echinococcus vogeli tapeworms. High E. vogeli prevalence among pacas indicates potential risk for humans living in E. vogeli-contaminated areas.

RESUMO

OBJECTIVE: The aim of this study is to assess the impact of lymphadenectomy (LND) on morbidity, survival, and cost for high-risk histologic types of endometrial cancer (EC). MATERIALS AND METHODS: We analyzed a multicenter retrospective cohort of 389 women with high-risk histotypes of EC (poor differenced tumors [G3], clear cell, serous papillary, and mixed mesodermal tumors) preoperatively confined to the corpus and diagnosed between 2000 and 2013. All patients underwent hysterectomy and bilateral salpingo-oophorectomy. A matched-pair analysis identified 97 pairs (97 with LDN and 97 without) equal in age, body mass index, comorbidities, International Federation of Gynecology and Obstetrics stage, and adjuvant treatment. Demographic data, pathologic examination results, perioperative morbidity, and survival were abstracted from medical records. Cost was provided by the cost unit of the local hospital. Disease-free and overall survival were analyzed using the Kaplan-Meier curves and Cox multivariable regression analysis. RESULTS: Both study groups were homogeneous in demographic data and pathologic examination results. At a median follow-up of 24.5 months (range, 5.4-146.3), disease-free survival (hazard ratio, 1.09; 95% confidence interval, 0.70-1.90) and overall survival (hazard ratio, 0.86; 95% confidence interval, 0.56-1.33) were similar in both groups regardless of nodal count. Positive nodes were found in 23.7%. Predictor factors of nodal involvement were advanced age (P = 0.024), deep myometrial invasion (P < 0.001), and high CA 125 levels (P = 0.003). In the LDN group, operating time, late postoperative complications, and surgical cost were higher (P < 0.05). There were no statistical differences between both groups relative to surgical morbidity. Early postoperative complications and hospital stay were lower in the LDN group. The global cost was similar for both groups (6027&OV0556; for the LND group and 5772&OV0556; for the no-LND group). CONCLUSIONS: Lymphadenectomy in high-risk histotypes of EC does not increase perioperative morbidity or global cost and has not benefit on survival.

RESUMO

Uterine carcinosarcoma is a rare high-grade endometrial cancer. Controversy has surrounded a number of aspects in the diagnosis and management of this unique clinicopathological entity, including the efficacy of adjuvant therapy, which has been questioned. An unusual surgico-pathological parameter with prognostic significance in a number of tumour sites is the lymph node ratio (LNR). The availability of data in this respect has been scarce in the literature. The primary aim of this collaborative study was to evaluate the prognostic value of LNR in patients with uterine carcinosarcoma. LNR is a recognized lymph node metric used to stratify prognosis in a variety of malignancies. In this European multinational retrospective study, 93 women with uterine carcinosarcoma were included in the final analysis. We used t-tests and ANOVA for comparison between quantitative variables between the groups, and chi-square tests for qualitative variables. A multivariate analysis using Cox regression analysis was performed to determine potential prognostic factors, including the LNR. Patients were grouped with respect to LNR in terms of 0%, 20% > 0% and >20%. The analysis revealed LNR to be a significant predictor of progression-free survival (HR 1.69, CI (1.12-2.55), p = 0.012) and overall survival (HR 1.71, CI (1.07-2.7), p = 0.024). However, LNR did not remain a significant prognostic factor on multivariate analysis. Due to limitations of the retrospective study, a prospective large multinational study, which takes into effect the most recent changes to clinical practice, is warranted to elucidate the value of the pathophysiological metrics of the lymphatic system associated with prognosis.

RESUMO

IMPORTANCE: Menopause hormone therapy (MHT) effectively alleviates menopausal symptoms. However, it is generally not recommended for breast cancer survivors, although the scientific evidence is scarce. OBJECTIVE: This study aimed to establish eligibility criteria for use of the MHT in breast cancer survivors based on a systematic review and meta-analysis of the literature. EVIDENCE REVIEW: We conducted exhaustive literature searches until June 2022 in MEDLINE, The Cochrane Library, and EMBASE, using a tailored strategy with a combination of controlled vocabulary and search terms related to breast cancer survivors and MHT. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and assessed the risk of bias using the Cochrane and Risk of Bias in Non-randomized Studies - of Interventions tools. The quality of the evidence was graded according to grading quality of evidence and strength of recommendations criteria (A, high; B, moderate; C, low; and D, very low). We categorized MHT use into four levels: category 1 (no restrictions on use), category 2 (the benefits outweigh the risks), category 3 (the risks generally outweigh the benefits), and category 4 (MHT should not be used). FINDINGS: A total of 12 studies met the eligibility criteria. Analysis of the three randomized clinical trials using combined MHT or tibolone revealed no significant differences concerning tumor recurrence (relative risk [RR], 1.46; 95% CI, 0.99-2.24). A combined analysis of randomized clinical trials, prospective, and retrospective trials found no elevated risk of recurrence (RR, 0.85; 95% CI, 0.54-1.33) or death (RR, 0.91; 95% CI, 0.38-2.19). The eligibility criteria for patients with hormone receptor (HR)-positive tumors fell into categories 3B and 3C for combined MHT or estrogen alone and 4A for tibolone. For HR-negative tumors, the category was 2B and 2C. CONCLUSIONS AND RELEVANCE: Our findings suggest that MHT could be a viable treatment alternative for breast cancer survivors experiencing menopausal symptoms, especially those with HR-negative tumors. Personalized management is recommended for each peri/postmenopausal woman facing a diminished quality of life because of menopause symptoms. Further randomized trials are needed before considering changes to current standards of care.

RESUMO

OBJECTIVE: The Cervantes-GSM questionnaire is a novel tool currently being developed to examine the impact of genitourinary symptoms on health-related quality of life in adult women with genitourinary syndrome of menopause (GSM). METHODS: A literature review and cognitive debriefing were conducted in women with GSM, which provided the basis for creating a draft questionnaire. This draft version was pilot-tested to check participant comprehension and ease of completion. The initial draft was then refined to obtain a 15-item version with five domains whose initial psychometric properties were analyzed in 130 adult women with GSM. The psychometric properties tested in this study were factorial structure, feasibility, reliability, and construct validity. RESULTS: The Cervantes-GSM 15-item questionnaire consists of five domains: vulvovaginal symptoms, urinary symptoms, psychological (emotions), interference with daily activities, and sexuality. The instrument was shown to be feasible and easy to complete, regardless of age or educational level. Internal consistency was high (Cronbach α = 0.88). Construct validity was supported by convergent-divergent validity showing higher correlation coefficients between items in their own domain (>0.70) than with the other items and domains in the questionnaire. Cervantes-GSM also showed known group validity with significant differences in total score and most domains (13-20 points, P < 0.01) regardless of whether women chose local treatment of their genitourinary symptoms. CONCLUSION: This study presents a novel questionnaire capable of assessing health-related quality of life in menopausal women with GSM. The tool has shown acceptable preliminary psychometric properties, including feasibility, factor structure, construct validity, and internal consistency.

RESUMO

Morris water maze (MWM) test is widely used to evaluate the learning and memory deficits in rodents. Image processing and pattern recognition can be used to analyse videos and recognize automatically the tracking in MWM. There are several commercial and free access software that allows analyzing the behavioral tasks although they also have limitations such as automation, cost, user intervention among other things. The aim of this paper was to develop a new image processing technique to automatically analyse the track of the rat in the MWM, which we called RatsTrack. The MWM test was performed with an animal model for Alzheimer, and the videos were recorded to measure the distance, time, and speed. The segmentation method based on the projection of the video frames was made for pool identification, eliminating the rat, while conserving the shape of the pool. Then, the Hough transformation was used to recognize the position and radius of the pool. Finally, the frame in which the rat is released into the pool was established automatically using mathematical morphology techniques and added as a plugin on free access ImageJ software. The new image processing technique, RatsTrack, successfully detected and located the pool and rat without user intervention, significantly decreasing operational time and providing results for distance, time, speed, and acceleration parameters of the MWM test. Alzheimer's rats compared with the control group presented significant data measured with the RatsTrack. RatsTrack is a plugin of ImageJ software and will be made freely available for public use.

RESUMO

Neurocysticercosis (NCC) is the most common parasitic disease affecting the nervous system and is a leading cause of acquired epilepsy worldwide, as well as cognitive impairment, especially affecting memory. The aim of this study was to evaluate the effect of NCC on spatial working memory and its correlation with hippocampal neuronal density, in a rat model of NCC. This experimental study was conducted on female (n = 60) and male (n = 73) Holtzman rats. NCC was induced by intracranial inoculation of T. solium oncospheres in 14 day-old-rats. Spatial working memory was assessed using the T-maze test at 3, 6, 9, and 12 months post-inoculation, and sensorimotor evaluation was performed at 12 months post-inoculation. Hippocampal neuronal density was evaluated by immunostaining of NeuN-positive cells of the CA1 region. Of the rats inoculated with T. solium oncospheres, 87.2% (82/94) developed NCC. The study showed a significant decline in spatial working memory over a 1-year follow-up period in rats experimentally infected with NCC. Males showed an early decline that started at 3 months, while females demonstrated it at 9 months. Additionally, a decrease in neuronal density was observed in the hippocampus of NCC-infected rats, with a more significant reduction in rats with cysts in the hippocampus than in rats with cysts in other brain areas and control rats. This rat model of NCC provides valuable support for the relationship between neurocysticercosis and spatial working memory deficits. Further investigations are required to determine the mechanisms involved in cognitive impairment and establish the basis for future treatments.

RESUMO

Circulating microRNAs (miRNAs) have aroused a lot of interest as reliable blood diagnostic biomarkers of Alzheimer's disease (AD). Here, we investigated the panel of expressed blood miRNAs in response to aggregated Aß1-42 peptides infused in the hippocampus of adult rats to mimic events of the early onset of non-familial AD disorder. Aß1-42 peptides in the hippocampus led to cognitive impairments associated with an astrogliosis and downregulation of circulating miRNA-146a-5p, -29a-3p, -29c-3p, -125b-5p, and-191-5p. We established the kinetics of expression of selected miRNAs and found differences with those detected in the APPswe/PS1dE9 transgenic mouse model. Of note, miRNA-146a-5p was exclusively dysregulated in the Aß-induced AD model. The treatment of primary astrocytes with Aß1-42 peptides led to miRNA-146a-5p upregulation though the activation of the NF-κB signaling pathway, which in turn downregulated IRAK-1 but not TRAF-6 expression. As a consequence, no induction of IL-1ß, IL-6, or TNF-α was detected. Astrocytes treated with a miRNA-146-5p inhibitor rescued IRAK-1 and changed TRAF-6 steady-state levels that correlated with the induction of IL-6, IL-1ß, and CXCL1 production, indicating that miRNA-146a-5p operates anti-inflammatory functions through a NF-κB pathway negative feedback loop. Overall, we report a panel of circulating miRNAs that correlated with Aß1-42 peptides' presence in the hippocampus and provide mechanistic insights into miRNA-146a-5p biological function in the development of the early stage of sporadic AD.

RESUMO

Objective: to develop eligibility criteria for use in non-gynecological cancer patients. Methods: We searched all the articles published in peer-reviewed journals up to March 2021. We utilized the PICOS standards and the following selection criteria: menopausal women with a history of non-gynecological and non-breast cancer who underwent hormone replacement therapy (HRT) using various preparations (oestrogens alone or in combination with a progestogen, tibolone, or tissue selective oestrogen complex) and different routes of administration (including oral, transdermal, vaginal, or intra-nasal). We focused on randomized controlled trials as well as relevant extension studies or follow-up reports, specifically examining recurrence and mortality outcomes. Results: Women colorectal cancer survivors who use MHT have a lower risk of death from any cause than those survivors who do not use MHT. Women who are skin melanoma survivors using MHT have a longer survival rate than non-MHT survivors. There is no evidence that women lung cancer survivors who use MHT have a different survival rate than those who do not use MHT. Conclusions: MHT is safe for women who have a history of colorectal, lung, or skin melanoma cancers.

RESUMO

(1) Background: This study aimed to analyze the impact of surgical approach on survival rates in women diagnosed with endometrial cancer. (2) Methods: A retrospective multicenter cohort of 1382 women diagnosed with EC was performed. A total of 684 (49.5%) women underwent minimally invasive surgery, 233 (34%) underwent robotic-assisted laparoscopy (RAL), 451 (66%) underwent conventional laparoscopy (LPS), and 698 (50.5%) underwent open surgery (OP). Sociodemographic features, tumor characteristics, and survival rates were analyzed in the whole sample and in a matched-pair model. (3) Results: Women operated on by OP were significantly older, presented more comorbidities, and had more aggressive tumors. Disease-free (DFS), overall (OS), and specific survival related to EC (SS) amounts were significantly higher for MIS compared to OP (p < 0.001). When matched by age, body mass index, comorbidities, ASA score, histological type, grade, myometrial invasion, and FIGO stage, 798 patients were selected. DFS, OS, and SS amounts were similar between the MIS and OP groups. (4) Conclusions: The surgical approach for women with EC does not impact DFS or OS amounts when matched by homogeneous groups.

RESUMO

This project aims to develop eligibility criteria for menopausal hormone therapy (MHT). The tool should be similar to those already established for contraception A consortium of scientific societies coordinated by the Spanish Menopause Society met to formulate recommendations for the use of MHT by women with medical conditions based on the best available evidence. The project was developed in two phases. As a first step, we conducted 14 systematic reviews and 32 metanalyses on the safety of MHT (in nine areas: age, time of menopause onset, treatment duration, women with thrombotic risk, women with a personal history of cardiovascular disease, women with metabolic syndrome, women with gastrointestinal diseases, survivors of breast cancer or of other cancers, and women who smoke) and on the most relevant pharmacological interactions with MHT. These systematic reviews and metanalyses helped inform a structured process in which a panel of experts defined the eligibility criteria according to a specific framework, which facilitated the discussion and development process. To unify the proposal, the following eligibility criteria have been defined in accordance with the WHO international nomenclature for the different alternatives for MHT (category 1, no restriction on the use of MHT; category 2, the benefits outweigh the risks; category 3, the risks generally outweigh the benefits; category 4, MHT should not be used). Quality was classified as high, moderate, low or very low, based on several factors (including risk of bias, inaccuracy, inconsistency, lack of directionality and publication bias). When no direct evidence was identified, but plausibility, clinical experience or indirect evidence were available, "Expert opinion" was categorized. For the first time, a set of eligibility criteria, based on clinical evidence and developed according to the most rigorous methodological tools, has been defined. This will provide health professionals with a powerful decision-making tool that can be used to manage menopausal symptoms.

RESUMO

OBJECTIVE: To assess the impact of confinement due to the coronavirus (Covid-19) pandemic on health-related quality of life (HRQoL) and resilience in peri- and postmenopausal women. MATERIAL AND METHODS: We used an online questionnaire which was sent between April 30th and May 13th, 2020 to women aged 40-70 years who were peri- or postmenopausal according to STRAW criteria. We used the 16-item Cervantes short-form scale (Cervantes-SF) to measure HRQoL, and the 14-item Wagnild and Young Resilience Scale (RS-14) to measure resilience. High scores on the Cervantes-SF indicate low HRQoL and high scores on the RS-14 indicate high levels of resilience. Covid-19 status, sociodemographic descriptors, and lifestyle variables were also evaluated. RESULTS: We included 2430 peri- and postmenopausal women with valid questionnaires. All items of the Cervantes-SF were completed in 2151 cases, whilst the RS-14 was completed in 2413 cases. There was a negative correlation between scores on the Cervantes-SF and RS-14 scales (Rho -0.350; p < 0.0001). Multiple linear regression analysis revealed a statistically significant association between Cervantes-SF scores and living with others (ß-coefficient -10.2; p < 0.001), use of antidepressants (ß 9.3; p < 0.001), physical activity (ß -8.6; p < 0.001) and sexual activity (ß -2.7; p < 0.001). Resilience was associated with the use of antidepressants (ß -5.9; p < 0.001), physical activity (ß 3.2; p < 0.001) and sexual activity (ß 1.7; p = 0.005). According to the multivariate analysis, there were no associations between either Covid-19 or menopausal status and HRQoL or resilience scores. CONCLUSIONS: During the period of mandatory Covid-19 confinement, peri- and postmenopausal women who engaged in physical and sexual activity had higher HRQoL and higher levels of resilience, whilst women who were using antidepressants had lower HRQoL and lower levels of resilience. HRQoL was greater in women who lived with others.

RESUMO

OBJECTIVES: To determine the predictive and criterion-based validity of the Cervantes-SF scale that measures the impact of menopause on Health-Related Quality of Life. METHODS: We recruited a noninstitutionalized sample of peri/postmenopausal women aged 40 to 65 years, who had their last menstrual cycle 12+ months prior to inclusion in the study of the psychometric validity of the Cervantes-SF scale. Predictive validity of the scale was confirmed for various health outcome measures administered concomitantly (years of disability-free life expectancy, work productivity and impact on daily activities, economic impact arising from loss of work productivity, hours of undisturbed sleep each day, and the utilization of healthcare facilities), whilst criterion validity was determined by the likelihood of identifying a moderate-to-severe vasomotor or genital syndrome requiring specific treatment. RESULTS: A sample of 308 peri/postmenopausal women with a mean age of 55.7 years (SD: 5.3 y) was analyzed in this study. A score >25 points on the dimension of vasomotor problems (or menopausal health) showed values of sensitivity and specificity > 80% for identifying women with moderate-severe vasomotor syndrome requiring pharmacological treatment. Predictive validity was confirmed for menopause-related health outcomes. A change of 6.7 points in the scale score, equivalent to the value of its minimal difference, is indicative of a significant increase in the degree of disability regarding work/day-to-day activities, greater economic loss due to decreased work productivity, fewer years of life expectancy without disability, fewer hours of undisturbed sleep, and more visits to the physician per year due to menopausal symptoms. CONCLUSIONS: These results confirm the criterion and predictive validity of the Cervantes-SF scale in peri/postmenopausal women.
