RESUMEN

Several risk factors are associated with fetal asphyxia. The main aim of this retrospective, analytical, case-control study was to determine whether assisted reproductive technologies (ART) could be considered one of these factors. In total, 162 cases of fetal asphyxia were compared to 361 controls where this event did not occur. We included 32 ART pregnancies, of which 12 were obtained through egg donations. Overall, 75% (24) of ART pregnancies experienced fetal asphyxia, suggesting ART increases the risk of fetal asphyxia by about 7 times. This finding is consistent with the literature. The pathogenesis of fetal asphyxia in ART pregnancies is currently unknown. Accordingly, this topic should be further investigated.

RESUMEN

OBJECTIVES: Although the knowledge on SARS-CoV-2 infection in pregnancy has greatly improved, there is still a lack of information on its role in the later stages of gestation. The aim of this study is to investigate whether SARS-CoV-2 discovered at delivery is associated with any obstetric or neonatal complications. METHODS: A retrospective case-control study was conducted at Department of Obstetrics, University Hospital Maggiore della Carità, Novara, Italy, from March 2020 to March 2023. Pregnant women admitted were tested for SARS-CoV-2. 168 women resulted positive at the time of delivery; the women were asymptomatic or paucisymptomatic. 170 negative women were selected as controls, selecting, for each SARS-CoV-2 positive patient, the patient who gave birth right before, if negative. Demographic and anamnestic characteristics, pregnancy, labor, and neonatal outcomes were evaluated. RESULTS: SARS-CoV-2 positive patients were more likely to have gestational diabetes (13.7 vs. 5.3 %) and required less frequently intrapartum analgesia (11.3 vs. 27 %) and labor augmentation (7.3 vs. 16.5 %). Post-partum hemorrhage rate was lower (13.7 vs. 22.9 %) and a shorter length of first and second stage of labor occurred. There were no statistically significant differences between the two groups regarding the mode of delivery and neonatal outcomes. CONCLUSIONS: SARS-CoV-2 positive patients have shorter labor length and a lower incidence of postpartum hemorrhage. Fewer obstetric interventions, as well as less use of intrapartum analgesia and oxytocin, could explain these findings. Moreover, gestational diabetes could increase susceptibility to infection. SARS-CoV-2 infection discovered at the time of delivery in asymptomatic or paucisymptomatic patients does not appear to increase the rate of cesarean delivery or other obstetric complications, and neonatal outcomes have not worsened.

RESUMEN

Pregnancy at advanced maternal age (AMA) is a condition of potential risk for the development of maternal-fetal complications with possible repercussions even in the long term. Here, we analyzed the changes in plasma redox balance and the effects of plasma on human umbilical cord mesenchymal cells (hUMSCs) in AMA pregnant women (patients) at various timings of pregnancy. One hundred patients and twenty pregnant women younger than 40 years (controls) were recruited and evaluated at various timings during pregnancy until after delivery. Plasma samples were used to measure the thiobarbituric acid reactive substances (TBARS), glutathione and nitric oxide (NO). In addition, plasma was used to stimulate the hUMSCs, which were tested for cell viability, reactive oxygen species (ROS) and NO release. The obtained results showed that, throughout pregnancy until after delivery in patients, the levels of plasma glutathione and NO were lower than those of controls, while those of TBARS were higher. Moreover, plasma of patients reduced cell viability and NO release, and increased ROS release in hUMSCs. Our results highlighted alterations in the redox balance and the presence of potentially harmful circulating factors in plasma of patients. They could have clinical relevance for the prevention of complications related to AMA pregnancy.

RESUMEN

Background and Objective: Menopause can be associated with many clinical manifestations: vasomotor symptoms, urogenital problems, and additional psychological disturbances, such as anxiety, mood changes, and sleep alterations. The prolonged lack of hormones also increases the risk of long-term consequences. Hormone Replacement Treatment (HRT) in menopause consists of the administration of estrogen, alone or associated to progesterone, to relieve these uncomfortable disturbances and to prevent the onset of other pathologic conditions. The aim of this study is to examine the prevalence of HRT use in a sample of menopausal women and their experience with menopause and HRT. This study also investigates the knowledge of general practitioners (GPs) and gynecologists about HRT and its prescription. Materials and Methods: We conducted a cross-sectional population survey on 126 women of 50-59 years in an industrial city in the North of Italy, Vercelli (Novara), in Eastern Piedmont. We also presented a questionnaire on the topic to 54 medical doctors (GPs and gynecologists) of the same area. Results: The prevalence of HRT use in our sample was 11.9%. In total, a good percentage of the users affirmed to be satisfied with HRT. Additionally, a minority of women reported being ideally against the use of replacement hormones, were advised against using HRT by doctors, and did not use it because of the fear of side effects. We found a positive association between patient education, health care attitude, and HRT usage. A significant number of women knew about HRT from the media, and most of them were not informed by a health professional. Despite this, the interviewed doctors considered their knowledge about HRT as 'good' and would recommend HRT: only 5.6% would not prescribe it. Conclusions: Our results highlight the need for information about HRT among patients and health professionals, along with the need for more effective communication, evaluation, and suggestion of treatment.

RESUMEN

BACKGROUND: Hysteroscopy plays a crucial role in diagnosing and managing various intrauterine pathologies. However, its execution can be influenced by patients' perception and understanding, which are often shaped by digital resources such as YouTubeTM. Given its popularity and accessibility, YouTubeTM has the potential to greatly influence patients' knowledge and expectations about this procedure, highlighting the need for accurate and reliable information. PURPOSE: This study aims to assess the reliability and quality of hysteroscopy information available to patients on YouTubeTM. Understanding the nature of information patients' access can help address their fears and potential misunderstandings about the procedure, consequently reducing the likelihood of suspension or postponement due to anxiety. METHODS: A comprehensive analysis of YouTubeTM was conducted, simulating the search process of a patient seeking information about hysteroscopy. The study evaluated the reliability and quality of 90 out of the first 100 hysteroscopy-related videos on YouTubeTM, scored by four gynecologists-two experienced hysteroscopists and two trainees. The videos were assessed for reliability and quality using the mDISCERN and Global Quality Scale (GQS) scores. RESULTS: The average mDISCERN and GQS scores for the evaluated videos were below the optimal three points, highlighting the lack of fluency, comprehensiveness, and reliability of the available information. Notably, while videos produced by experts, including doctors and professional channels, had higher scores, they still fell short of the minimum score of 3. These videos also were not considered more suitable for either patients or trainees. Videos that were assessed as reliable (mDISCERN ≥ 3) were observed to be longer and were more frequently produced by doctors. These videos were suggested more to trainees rather than patients. Similarly, videos deemed as fluent and comprehensive (GQS ≥ 3) were longer and were more often recommended to patients. CONCLUSIONS: While YouTubeTM is a widely used source of medical information, the quality and reliability of hysteroscopy videos on the platform are poor. The strategic use of selected, high-quality hysteroscopy videos can enhance procedure success and alleviate patient fears. However, the unsupervised discovery of information by patients could potentially lead to procedure failure or an elevated level of stress due to misleading or incorrect information.

RESUMEN

Circulating extracellular vesicles (EVs) may play a pathophysiological role in the onset of complications of subarachnoid hemorrhage (SAH), potentially contributing to the development of vasospasm (VP). In this study, we aimed to characterize circulating EVs in SAH patients and examine their effects on endothelial and smooth muscle cells (SMCs). In a total of 18 SAH patients, 10 with VP (VP), 8 without VP (NVP), and 5 healthy controls (HC), clinical variables were recorded at different time points. EVs isolated from plasma samples were characterized and used to stimulate human vascular endothelial cells (HUVECs) and SMCs. We found that EVs from SAH patients expressed markers of T-lymphocytes and platelets and had a larger size and a higher concentration compared to those from HC. Moreover, EVs from VP patients reduced cell viability and mitochondrial membrane potential in HUVECs and increased oxidants and nitric oxide (NO) release. Furthermore, EVs from SAH patients increased intracellular calcium levels in SMCs. Altogether, our findings reveal an altered pattern of circulating EVs in SAH patients, suggesting their pathogenic role in promoting endothelial damage and enhancing smooth muscle reactivity. These results have significant implications for the use of EVs as potential diagnostic/prognostic markers and therapeutic tools in SAH management.

RESUMEN

(1) Background: Aggressive angiomyxoma is a mesenchymal cancer that is rare during pregnancy. It is a neoplasm that relapses and infiltrates the nearest structures. Our aim is to evaluate the management and outcomes of an observed case, in light of the current literature. (2) Methods: We observed this condition at the "Maggiore della Carità" Hospital in Novara (Italy) in a patient with an initial twin pregnancy and a suspected pelvic mass. The words "angiomyxoma" and "pregnancy" were searched on the main online scientific search sources (PubMed, Google Scholar, Scopus, WES, and Embase, etc.). (3) Results: The patient underwent surgery with a complicated follow-up, but recent negative controls. We analyzed the literature about the topic and found only 24 similar clinical cases. (4) Conclusions: Considering the current literature, it is useful to assess an aggressive angiomyxoma in the differential diagnosis of soft masses in pregnant women. The treatment of choice is surgical excision, and vaginal delivery is feasible. The therapeutic decision depends on each case.

RESUMEN

BACKGROUND: Laparoscopic segmental bowel resection, disc excision and rectal shaving are described as surgical options for the treatment of bowel endometriosis, but the gold standard has not yet established. The aim of the study is to investigate the efficacy of the laparoscopic bowel shaving technique in terms of pain symptomatology and to analyse early and late postoperative complications. METHODS: Retrospective cohort study of a series of 703 consecutive patients treated between January 2014 and December 2019 in a tertiary care referral centre. All patients underwent laparoscopic bowel shaving with concomitant radical excision of DIE. RESULTS: Bilateral posterolateral parametrectomy and ureterolysis were performed, respectively, in 314 (44.7%) and 318 cases (45.2%). A radical hysterectomy was performed in 107 cases (82.9%). Postoperative complications were infrequent: 17 patients required a reoperation (2.4%) and in this subgroup we registered 2 rectovaginal fistulas (0.3%), 4 patients received blood transfusion (0.6%), 12 patients (1.7%) experienced postoperative fever, 6 patients experienced impaired bladder voiding (0.9%) after 6 months. Median follow-up was 14 months. The study reported good clinical and surgical results, with a regression of symptoms (p < 0.0001) and an overall rate of recurrence of 6.5%. Clinical and instrumental criteria of bowel endometriosis relapse were exclusively detected in 5 patients (0.8%). Eleven patients (1.7%) with relapsed endometriosis were reoperated. CONCLUSIONS: Bowel shaving is a feasible and valuable surgical procedure. It is only the last step of a complex surgery which is aimed to minimize the residual quote of infiltrating nodule and requires a multidisciplinary team to achieve optimal treatment preoperatively, intraoperatively and postoperatively.

RESUMEN

Our aim was to evaluate the intra- and inter-operator agreement in cardiotocography (CTG) traces analysis using the 2015 FIGO classification guidelines, and whether the educational background and the knowledge of anamnestic data can influence the interpretation of CTG traces. A retrospective interpretation of 73 intrapartum CTGs at time 0 (T0) for a first blind interpretation and at time 1 (T1) two months later with additional anamnestic pregnancy information was made by eight different operators (four obstetricians and four midwives with different years of work experience). The intra-observer agreement demonstrates that midwifes are more concordant than obstetricians with a mean of 77.05% versus a mean of 65.75%. There is moderate inter-observer agreement in classifying a CTG trace as 'normal'; on the contrary, there is no consensus on the 'suspect' and 'pathological' classification category.IMPACT STATEMENTWhat is already known on this subject? Interpretation of intrapartum CTG is affected by significant subjective variables with relevant intra- and inter-observer lack of optimal agreement, especially in case of abnormal o pathologic findings.What do the results of this study add? Clinical data seem to play a role in interpretation of suspicious and pathological traces while they do not affect the rate of agreement for normal traces. Midwives tend to be less influenced by anamnestic data in visual CTG interpretation. Instead, obstetricians tend to be more focussed on clinical data and clinical setting that, as a consequence, tend to have great impact on CTG trace interpretation.What are the implications of these findings for clinical practice and/or further research? Cooperation among obstetricians and between obstetricians and midwives should be encouraged in order to optimise CTG reading and improve maternal and neonatal outcomes. Regarding the influence of clinical parameters in classification of intrapartum CTG traces, especially in case of abnormal CTG traces, it should be conceivable to improve medical skills in CTG blind interpretation and further investigate which clinical parameters are mainly related with an augmented risk of foetal asphyxia and adverse neonatal outcomes.

RESUMEN

BACKGROUND: In response to the COVID-19 pandemic, drastic measures for social distancing have been introduced also in Italy, likely with a substantial impact in delicate conditions like pregnancy and puerperium. The study aimed to investigate the changes in lifestyle, access to health services, and mental wellbeing during the first Italian lockdown in a sample of Italian pregnant women and new mothers. METHODS: We carried out a web-based survey to evaluate how pregnant women and new mothers were coping with the lockdown. We collected data about healthy habits (physical exercise and dietary habits), access to health services (care access, delivery and obstetric care, neonatal care, and breastfeeding), and mental wellbeing (psychological well-being and emotive support). Descriptive analysis was performed for both groups of participants, whereas a Poisson analysis was used to measure the association between some structural variables (age, education, socio-economic data, partner support, contact, free time, previous children, and pregnancy trimester) and anxiety or depression, difficulties in healthy eating and reduction in physical activity after lockdown started. Chi2 and Adjusted Prevalence Ratios were estimated only for pregnant women. RESULTS: We included 739 respondents (response rate 85.8 %), 600 were pregnant (81.2 %), and 139 (18.8 %) had delivered during lockdown (new mothers). We found a high score for anxiety and depression in 62.8 % of pregnant women and 61.9 % of new mothers. During the lockdown, 61.8 % of pregnant women reduced their physical exercise, and 44.3 % reported eating in a healthier way. 94.0 % of new mothers reported to have breastfed their babies during the hospital stay. Regarding the perceived impact of restrictive measures on breastfeeding, no impact was reported by 56.1 % of new mothers, whereas a negative one by 36.7 %. CONCLUSIONS: The high prevalence of anxiety and depressive symptoms in pregnant women and new mothers should be a public health issue. Clinicians might also recommend and encourage "home" physical exercise. On the other hand, about half of the sample improved their approach towards healthy eating and a very high breastfeeding rate was reported soon after birth: these data are an interesting starting point to develop new strategies for public health.

RESUMEN

BACKGROUND/AIMS: Oxidative stress and mitochondria dysfunction could be involved in the onset of non-alcoholic fatty liver disease (NAFLD) and in its progression to non-alcoholic steatohepatitis (NASH). Estrogens/phytoestrogens could counteract liver fat deposition with beneficial effects against NAFLD by unclear mechanisms. We aimed to analyze the protective effects elicited by genistein/estradiol in hepatocytes cultured in NAFLD-like medium on cell viability, triglycerides accumulation, mitochondrial function and oxidative stress and the role of NLRP3 inflammasome, toll like receptors 4 (TLR4), Akt and 5' AMP-activated protein kinase (AMPK)α1/2. METHODS: Human primary hepatocytes/hepatoma cell line (Huh7.5 cells) were incubated with a 2 mM mixture of oleate/palmitate in presence/absence of genistein/17ß-estradiol. In some experiments, Huh7.5 cells were exposed to various inhibitors of the above pathways and estrogenic receptors (ERs) and G protein-coupled estrogen receptor (GPER) blockers, before genistein/17ß-estradiol. Cell viability, mitochondrial membrane potential, reactive oxygen species and triglycerides content were examined by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT), 5,51,6,61-tetrachloro-1,11,3,31 tetraethylbenzimidazolyl carbocyanine iodide (JC-1), 2,7-dichlorodihydrofluorescein diacetate (H2DCFDA) and the Triglyceride Colorimetric Assay. The expression/activation of kinases was analyzed by means of Western blot. RESULTS: Genistein/17ß-estradiol protected hepatocytes against NAFLD-like medium, by preventing the loss of cell viability and mitochondrial function, triglycerides accumulation and peroxidation. The blocking of kinases, ERs and GPER was able to reduce the above effects, which were potentiated by NLRP3 inflammasome. CONCLUSION: Our findings suggest novel mechanisms underlying the protective effects elicited by phytoestrogens/estrogens against NAFLD/NASH and open novel therapeutic perspectives in the management of NAFLD in postmenopausal women.

RESUMEN

PURPOSE: To assess the association between confined placental mosaicism (CPM) and adverse pregnancy outcome. METHODS: A retrospective cohort study was carried out evaluating the outcome of pregnancies with and without CPM involving a rare autosomal trisomy (RAT) or tetraploidy. Birthweight, gestational age at delivery, fetal growth restriction (FGR), Apgar score, neonatal intensive care admission, preterm delivery, and hypertensive disorders of pregnancy were considered. RESULTS: Overall 181 pregnancies with CPM and 757 controls were recruited. Outcome information was available for 69% of cases (n = 124) and 62% of controls (n = 468). CPM involving trisomy 16 (T16) was associated with increased incidence of birthweight <3rd centile (P = 0.007, odds ratio [OR] = 11.2, 95% confidence interval [CI] = 2.7-47.1) and preterm delivery (P = 0.029, OR = 10.2, 95% CI = 1.9-54.7). For the other RATs, an association with prenatally diagnosed FGR was not supported by birthweight data and there were no other strong associations with adverse outcomes. CONCLUSION: Excluding T16, the incidence of adverse pregnancy outcomes for pregnancies carrying a CPM is low. RATs can also be identified through genome-wide cell-free DNA screening. Because most of these will be attributable to CPMs, we conclude that this screening is of minimal benefit.

RESUMEN

INTRODUCTION: The aims of the study were to evaluate quality of life, cosmetic results and surgical outcomes of robotic single-site and robotic multiport total laparoscopic hysterectomy with sentinel lymph node mapping in women treated for low-risk endometrial cancer. MATERIAL AND METHODS: The study is a prospective, multicenter, case-control study conducted at Ospedale Santa Chiara in Trento and Novara and Pavia University Hospitals. Seventy-six consecutive patients with a biopsy-confirmed diagnosis of low-risk endometrial cancer or atypical endometrial hyperplasia who between January 2017 and January 2019 had undergone robotic total laparoscopic hysterectomy and sentinel lymph node mapping were included. Data on surgical outcomes, quality of life and cosmetic results were prospectively collected and analyzed based on the surgical approach with robotic single-site vs robotic multiport assistance. Patients' clinical characteristics, intra-operative parameters, sentinel lymph node mapping results and postoperative findings were prospectively recorded. Clinical follow up was performed 4 weeks and 6 and 12 months after surgery. Fifty-one patients underwent a robotic multiport procedure and 25 patients a robotic single-site surgery. RESULTS: There was one significant difference between the two groups in terms of patient characteristics: mean body mass index (BMI) in the multiport group was 29 kg/m2 vs 24.8 kg/m2 in the single-site group (P value <.001). After univariate and multivariate analysis on intraoperative and postoperative findings, a shorter surgical time was observed in the single-site cohort than in the multiport group (148.7 vs 158.2 minutes, P value .0182). BMI also had a significant effect on surgical time (P = .022). No differences were seen in terms of sentinel lymph node detection: the bilateral detection rate was 96.1% for multiport (66.7% bilateral, 29.4% monolateral) and 96% for single-site (76% bilateral, 20% monolateral) procedures. No differences between the two approaches were identified with regard to postoperative complications, pain, cosmetic results or quality of life comparisons. CONCLUSIONS: For the treatment of low-risk endometrial cancer and atypical endometrial hyperplasia with total hysterectomy and sentinel lymph node mapping, the robotic single-port approach is comparable to the multiport procedure in terms of intraoperative and postoperative findings, and has an advantage in terms of shorter surgical times. Further studies are required to identify possible differences in quality of life and cosmetic results.

RESUMEN

To describe a rare case of a singleton 8-week cornual pregnancy (CP), treated by laparoscopic incision of the uterine wall, the ectopic pregnancy was removed and the uterine site was sutured with interrupted sutures. A 21-year-old woman was admitted for suspected singleton CP at week 8. Clinical examination, b-hCG increase, and transvaginal ultrasonography (TU) were used to monitor the suspected diagnosis of an ectopic pregnancy. Following failure of methotrexate administration, surgeons performed a laparoscopy. The CP removal was performed by laparoscopic incision, enucleating the corneal mass and suturing the uterine site of the ectopic pregnancy with interrupted sutures. Intraoperative and postoperative complications and uterine integrity preservation were studied. Postoperative recovery period was normal, without intraprocedural or postprocedural complications.Uterine integrity was preserved. No further therapeutic interventions were needed in follow-up. This study confirmed the feasibility, safety and efficacy of performing a safe, minimally invasive, laparoscopic treatment of an early unruptured CP, without intraoperative and postoperative complications, with a normal postoperative recovery period and preservation of uterine integrity.

RESUMEN

BACKGROUND/AIMS: estrogens and phytoestrogens exert hepatoprotection through mechanisms not clearly examined yet. Here, we investigated the protective effects exerted by 17ß-estradiol and genistein against oxidative stress in hepatocytes and hepatic stellate cells (HSCs) and the involvement of specific receptors and the intracellular signalling. METHODS: Huh7.5 and LX-2, alone or in co-culture with Huh7.5, were treated with 17ß-estradiol and genistein alone or in the presence of menadione and of estrogen receptors (ERs) and G protein-coupled-estrogenic-receptors (GPER) blockers. Cell viability, mitochondrial membrane potential and oxidant/antioxidant system were measured by specific kits. Western Blot was used for the analysis of Akt and p38-mitogen-activated-protein kinases (MAPK) activation and α-smooth-muscle actin expression. RESULTS: In Huh7.5, 17ß-estradiol and genistein prevented the effects of peroxidation by modulating Akt and p38MAPK activation. Similar antioxidant and protective findings were obtained in LX-2 of co-culture experiments, only. ERs and GPER blockers were able to prevent the effects of 17ß-estradiol and genistein. CONCLUSION: In Huh7.5 and LX-2, 17ß-estradiol and genistein counteract the effects of peroxidation through the involvement of ERs and GPER and by an intracellular signalling related to Akt and p38MAPK. As concerning LX-2, paracrine factors released by Huh7.5 play a key role in protection against oxidative stress.

RESUMEN

STUDY OBJECTIVE: To demonstrate our developed nerve-preserving technique during laparoscopic sacropexy (LSP) for multicompartment pelvic organ prolapse. DESIGN: A step-by-step demonstration of our surgical procedure on video (Canadian Task Force classification II-2). Informed consent was obtained from the subject, and the applicable Institutional Review Board provided approval. SETTING: Although sacropexy does remain the 'gold standard' procedure for apical prolapse [1], the subjective outcome of the procedure has been reported to be not so satisfactory as its anatomic outcome [2]. New onset bowel symptoms have been observed with voiding and sexual dysfunctions [3]. Published data revealed a correlation between iatrogenic denervation during LSP and postoperative dysfunctions [4-6]. We adopted a nerve-preserving approach with the aim of reducing the iatrogenic morbidity. INTERVENTIONS: Our surgical nerve-preserving LSP technique from the promontory down to the right uterosacral ligament and the rectovaginal space proceeds in 3 steps: Step 1: Opening the peritoneum. The peritoneum is opened just medial to the right common iliac artery, approximately 20 to 30 mm above the sacral promontory, allowing a safe approach in an area far from nerves and vascular structures. Peritoneal incision is extended toward the promontory. The underlying presacral fascia containing the right hypogastric nerve (rHN) is identified and incised longitudinally. The presacral fascia and the rHN are then pushed medially to expose the longitudinal anterior vertebral ligament; the finding of the middle sacral veins represents the limit of any further medial dissection. Opening and displacement of the prevertebral fascia are not mandatory. Step 2: Opening the peritoneum of the right pelvic sidewall, respecting the integrity of the presacral fascia and of the rHN contained within it. An inverted L-shaped peritoneal incision extending from the sacral promontory up to the left uterosacral ligament is completed, with care taken to preserve the rHN identified previously. In proximity to the uterus, the dissection line crosses the upper edge of the right uterosacral ligament at its proximal third and extends medially. The rectovaginal space is opened and joined to the peritoneal tunnel with a section of the superficial layer of the right uterosacral ligament, preserving its deep nervous portion. Step 3: Dissection of the rectovaginal space, respecting the integrity of the rectal fascia. The rectovaginal space is fully dissected, and at its caudal edge the dissection is carried out laterally to the rectum upward to identify the pelvic parietal fascia covering the levator ani muscle, in the middle to the cranial edge of the perineal body. Preservation of the rectal fascia prevents possible injury to the middle rectal vessels and the rectal branches of the inferior hypogastric plexus, which runs close to the pelvic floor. The complete dissection of the rectovaginal space appears in an inverted V-shaped space covering approximately two-thirds of the posterior vaginal wall, with the apex at the convergence of the uterosacral ligaments. The procedure is completed with dissection of the vesicovaginal space through the creation of an avascular triangular-shaped space with the apex at the dorsal end of the bladder trigone and laterally limited by the superficial vascular layer of the vesicouterine ligaments. The bladder branches of the inferior hypogastric plexus run far from the surgical field in the deep portion of the vesicouterine ligaments. CONCLUSION: A nerve-sparing approach to pelvic spaces during LSP is feasible following well-defined surgical steps, which allow the surgeon to visualize all of the nerve pathways and potentially dangerous anatomic structures.

RESUMEN

Deep infiltrating endometriosis (DIE) is a complex disease that impairs the quality of life and the fertility of women. Colorectal DIE accounts for 70% to 93% of all the intestinal endometriotic sites and frequently needs a surgical approach. However, the indications for the surgical management of this condition are still controversial. From March 2010 to June 2014, we scheduled 33 consecutive patients presenting with retrocervical-rectal DIE of any diameter not involving the mucosa nor producing rectal stenosis >50% for laparoscopic robotic-assisted nerve-sparing rectal nodulectomy (LRN). All patients were examined preoperatively, at 3 months and 6 months postoperatively, and yearly thereafter. Dysmenorrhea, dyschezia, dyspareunia, and dysuria were evaluated on a 10-point visual analog scale. Among the 33 enrolled patients, 31 (93.9%) fulfilled the selection criteria and were submitted to LRN. In 1 out of 31 available patients (3.2%), a segmental bowel resection was considered necessary for prudential purpose at the end of the nodulectomy procedure. No laparotomic conversion was performed in any case. A wide variety of associated surgical procedures were performed in 25 of 30 patients (83.3%). No intraoperative complications were observed. One grade 3b and 2 grade 1 postoperative complications were recorded. The mean larger axis of the excised nodules measured on the formalin-fixed specimen was 26.4 mm. We found significant improvements in patient symptoms at a 3-month follow-up which persisted over the time. We observed 2 (6.7%) recurrences of intestinal endometriosis and 1 (3.3%) recurrence of chronic pelvic pain without clinical and/or radiologic evidence of endometriotic lesions. The mean follow-up time was 27.6 months. We believe that LRN is feasible and safe and shows promising results in terms of radicality, anatomic recurrence rate, and pain recurrence rate for treating isolated retrocervical-rectal DIE not involving the mucosa, without limiting this procedure to nodules smaller than 3 cm.

RESUMEN

BACKGROUND/AIM: Previous reports have made it hypothetically possible that human chorionic gonadotropin (hCG) could protect against the onset of pregnancy-related pathological conditions by acting as an antioxidant. In the present study we planned to examine the effects of hCG against oxidative stress in human umbilical vein endothelial cells (HUVEC). METHODS: HUVEC were subjected to peroxidation by hydrogen peroxide. The modulation of nitric oxide (NO) release by hCG and its effects on cell viability, glutathione (GSH) levels, mitochondrial membrane potential and mitochondrial transition pore opening (MPTP) were examined by specific dyes. Endothelial and inducible NO synthase (eNOS and iNOS), Akt and extracellular -signal-regulated kinases 1/2 (ERK1/2) activation and markers of apoptosis were analyzed by Western Blot. RESULTS: In HUVEC, hCG reduced NO release by modulating eNOS and iNOS. Moreover, hCG protected HUVEC against oxidative stress by preventing GSH reduction and apoptosis, by maintaining Akt and ERK1/2 activation and by keeping mitochondrial function. CONCLUSION: The present results have for the first time shown protective effects exerted by hCG on vascular endothelial function, which would be achieved by modulation of NO release, antioxidant and antiapoptotic actions and activation of cell survival signalling. These findings could have clinical implications in the management of pregnancy-related disorders.

RESUMEN

Children, women, and older people suffer different types of violence, which appears to have been exacerbated during the COVID-19 pandemic and the relative lockdown. The aim of this study is to analyze the literature about gender violence and abuse in the different ages of life and during the COVID-19 lockdown. Data were obtained from an electronic literature search using various online sources such as PubMed, Google Scholar, Science Direct and Web of Science. The terms "child abuse" were the most frequently used, followed in frequency by "gender violence," "femicide," and, lastly, "elderly abuse." The first studies considered gender-based violence as a purely physical problem, then, progressively, the analysis focused on the psychological point of view of the issue. There was a greater number of studies in 2020 about violence in comparison with previous years. The social and scientific attention to gender-based violence appeared to be very poor, especially in the case of older people abuse. It is necessary to increase general attention to the topic to correctly identify each form of abuse and to be able to take care of the subjects most at risk.
