RESUMEN

Background: SARS-CoV-2 positive pregnant women are at higher risk of adverse outcomes, but little evidence is available on how variants impact that risk. We aim to evaluate maternal and perinatal outcomes among unvaccinated pregnant women that tested positive for SARS-CoV-2, stratified by pre-Delta, Delta, and Omicron periods. Methods: This prospective study enrolled women from March 2020 to September 2022. Exposure to the different SARS-CoV-2 variants was defined by their periods of predominance. The primary outcome was severe maternal adverse outcome defined as either intensive care unit admission, acute respiratory distress syndrome, advanced oxygen supplementation, or maternal death. The secondary outcomes were preterm birth and other perinatal outcomes. Findings: Overall, 1402, 262, and 391 SARS-CoV-2 positive pregnant women were enrolled during the pre-Delta, Delta, and Omicron periods respectively. Severe maternal adverse outcome was reported in 3.4% (n = 947/1402; 95% confidence intervals (95%CI) 2.5-4.5), 6.5% (n = 7/262; 95%CI 3.8-10.2), and 1.0% (n = 4/391; 95%CI 0.3-2.6) of women during the pre-Delta, Delta, and Omicron periods. The risk of severe maternal adverse outcome was higher during the Delta vs pre-Delta period (adjusted risk ratio (aRR) = 1.8; 95%CI 1.1-3.2) and lower during the Omicron vs pre-Delta period (aRR = 0.3; 95%CI, 0.1-0.8). The risks of hospitalization for COVID-19 were 12.6% (n = 176/1402; 95%CI 10.9-14.4), 17.2% (n = 45/262; 95%CI 12.8-22.3), and 12.5% (n = 49/391; 95%CI 9.4-16.2), during the pre-Delta, Delta, and Omicron period, respectively. Pregnancy complications occurred after SARS-CoV-2 exposure in 30.0% (n = 363/1212; 95%CI 27.4-32.6), 35.2% (n = 83/236; 95%CI 29.1-41.6), and 30.3% (n = 105/347; 95%CI 25.5-35.4) of patients during the pre-Delta, Delta, and Omicron periods, respectively. Stillbirths were reported in 0.5% (n = 6/1159; 95%CI 0.2-1.1), 2.8% (n = 6/210; 95%CI 1.0-6.0), and 0.9% (n = 2/213; 95%CI 0.1-3.4) or patients during the pre-Delta, Delta, and Omicron periods respectively. Interpretation: The Delta period was associated with a higher risk of severe maternal adverse outcome and the Omicron period with a lower risk of severe adverse outcome compared to pre-Delta era. The reported risk of hospitalization was high during the Omicron period and should not be trivialized. Funding: Swiss Federal Office of Public Health, Fondation CHUV.

RESUMEN

BACKGROUND: Minimally invasive surgery is the standard approach in early-stage endometrial cancer according to evidence showing no compromise in oncological outcomes, but lower morbidity compared with open surgery. However, there are limited data available on the oncological safety of the use of intrauterine manipulators in endometrial cancer. PATIENTS AND METHODS: This prospective multicenter study included patients with endometrial cancer undergoing laparoscopic staging surgery with the use of an intrauterine manipulator. We obtained three different sets of peritoneal washings: at the beginning of the surgical procedure, after the insertion of the intrauterine manipulator, and after the closure of the vaginal vault. The rate of positive peritoneal cytology conversion and its association with oncological outcomes was assessed. RESULTS: A total of 124 patients were included. Peritoneal cytology was negative in 98 (group 1) and positive in 26 (group 2) patients. In group 2, 16 patients presented with positive cytology at the beginning of the surgery (group 2a) and 10 patients had positive cytology conversion during the procedure (group 2b). Recurrence rate was significantly different among the study groups, amounting to 9.2%, 25.0%, and 60.0% for groups 1, 2a, and 2b, respectively (p < 0.001). Group 1 showed the best recurrence-free and overall survival, followed by group 2a, while patients in group 2b had the worst oncological outcomes (p = 0.002 and p = 0.053, respectively). Peritoneal cytology was an independent predictor of recurrence and death on multivariable analysis. CONCLUSION: A total of 8.1% of patients with endometrial cancer undergoing minimally invasive surgery with intrauterine manipulation showed positive peritoneal cytology conversion associated with significantly worse oncological outcome.

RESUMEN

Domestic Violence at the University Emergency Department Bern: A Retrospective Analysis from 2006 to 2016 Abstract. Domestic Violence (DV) is considered as one of the largest medical risks worldwide. In Switzerland, DV is defined as offence requiring public prosecution since 2004. The present retrospective cohort study aims to investigate cases of DV in one of the largest Swiss emergency departments. The aggressors are predominantly male and either (ex-)partner or (ex-)husband of the victim. The head and the extremities are most often injured. Strangulation was documented in 16 % of the cases. Prevalence in our ED is very low with 0.07 % in 2016 (overall 0.09 % 2006-2016) and much lower compared with international data. We assume that we face many unreported cases and that victims are reluctant to seek medical help. Healthcare professionals should receive regular education in domestic violence, standards of care must be defined, and a sensitive and open-minded communication style is essential.

RESUMEN

OBJECTIVE: The objectives of the study were to highlight some of the differences in training systems and opportunities for training in gynecologic oncology across Europe and to draw attention to steps that can be taken to improve training prospects and experiences of European trainees in gynecologic oncology. METHODS: The European Network of Young Gynaecological Oncologists national representatives from 34 countries were asked to review and summarize the training system in their countries of origin and fulfill a mini-questionnaire evaluating different aspects of training. We report analysis of outcomes of the mini-questionnaire and subsequent discussion at the European Network of Young Gynaecological Oncologists national representatives Asian Pacific Organization for Cancer Prevention meeting in Istanbul (April 2010). RESULTS: Training fellowships in gynecologic oncology are offered by 18 countries (53%). The median duration of training is 2.5 years (interquartile range, 2.0-3.0 years). Chemotherapy administration is part of training in 70.5% (24/34) countries. Most of the countries (26/34) do not have a dedicated national gynecologic-oncology journal. All trainees reported some or good access to training in advanced laparoscopic surgical techniques, whereas 41% indicated no access, and 59% some access to training opportunities in robotic surgery. European countries were grouped into 3 different categories on the basis of available training opportunities in gynecologic oncology: well-structured, moderately structured, and loosely structured training systems. CONCLUSIONS: There is a need for further harmonization and standardization of training programs and structures in gynecologic oncology across Europe. This is of particular relevance for loosely structured countries that lag behind the moderately structured and well-structured ones.

RESUMEN

PURPOSE: The production of epithelial neutrophil activating peptide-78 (NA-78) and the interleukins IL-8 and IL-6 by endometrial stromal cells is stimulated by pro-inflammatory interleukin-1 (IL-1) and tumour necrosis factor-α (TNF-α). IL-8 is suggested to play a role in the pathogenesis of endometriosis, and in these women the peritoneal fluid concentrations of ENA-78 and IL-8 are increased. TNF-α has been tested together with interferon-γ because of their cooperative stimulation of IL-6. The release of IL-8, however, is inhibited with increasing interferon levels. The aim of the study was the analysis of the production of ENA-78, IL-6 and IL-8 by cultured human endometrial stromal cells in the presence of varying concentrations of IL-1ß, TNF-α, and interferon-γ. METHODS: Eutopic endometrial tissue was obtained from seven cycling, endometriosis-free women undergoing laparoscopy for reasons of infertility or pain. The release of ENA-78, IL-8 and IL-6 by the isolated and monolayer cultured stromal cell fraction in the presence of IL-1ß (0.08 to 50 ng/mL), TNF-α, and interferon-γ (both 20 to 500 ng/mL) was determined. RESULTS: IL-1ß stimulated the production of IL-8, IL-6, and ENA-78 dose dependently from 0.08 to 2.0 ng/mL (ENA-78) or to 10 ng/mL (IL-8, IL-6); at 50 ng/mL a decrease in release was observed for IL-8 and IL-6. TNF-α stimulation yielded a plateau between 20 and 100 ng/mL. Interferon-γ stimulated IL-6 and inhibited IL-8 production above 20 ng/mL. ENA-78 release was largely unaffected by interferon-γ. CONCLUSIONS: IL-1ß and TNF-α stimulate stromal cytokine production cumulatively with different dose-response curves. The presence of interferon-γ has opposite effects on IL-8 and IL-6. TNF-α and interferon-γ should be investigated separately in future in vitro studies with endometrial cells and explants.

RESUMEN

Endometrial cancer is one of the more frequent and most lethal gynaecological cancer types. Since it occurs more frequently in elderly and overweight patients, a pre-operative staging method would be beneficial. The growth of solid neoplasms is always accompanied by neovascularisation. Tumour endothelial markers (TEMs) are a group of recently described endothelial cell surface markers that appear to be specific to neoplastic tissue. This study aimed to investigate the potential usefulness of TEM assessment in the endometrium by comparing the transcriptional expression of TEMs in the normal endometrium with endometroid adenocarcinoma tissue. Tissues were lysed and the RNA was extracted, assessed and reverse transcribed in one batch. Real-time quantitative PCR was performed for TEM-1, -2, -6, -7, -7r and -8. GAPDH, ß-actin and ribosomal protein L13A (RPL13A) were used as control genes. TEM-8 showed the highest expression level in all of the groups. TEM-1 showed higher expression levels in the normal endometrium than in the tumour tissues. For the remaining TEMs, we found a higher expression in the cancer samples than in the normal endometria. Statistical significance of this difference was achieved for TEM-1, -2 and-7. No clear correlation was noted between the tumour stage and the level of TEM-1, -6 and -8 expression. Apart from TEM-6, the highest expression in FIGO I cancer stages was noted in the remaining TEMs. Our results showed that for most of these tumour endothelial markers, gene expression was slightly higher in the endometrial carcinoma tissue samples than in the endometrium of normal cycling women. However, with the possible exception of TEM-8 and -6, absolute expression levels were generally low, indicating that most TEMs may only be specifically expressed in a restricted number of cancer types (e.g., colorectal). Therefore, TEMs may not be useful in the context of endometrial cancer.

RESUMEN

BACKGROUND: This study aimed to compare the safety and efficacy of laparoscopy and laparotomy in the surgical treatment of early endometrial cancer, especially in obese women. METHODS: The results obtained after laparoscopic surgical treatment of early endometrial cancer (International Federation of Gynecology and Obstetrics (FIGO) stage 1 or 2) in patients between 1996 and 2007 were compared with an age- and tumour-matched historical group of patients treated with laparotomy between 1988 and 1996. All the patients underwent hysterectomy, bilateral salpingo-oophorectomy, and pelvic + or - paraaortic lymphadenectomy. RESULTS: Both groups included 120 patients with a preoperative diagnosis of early endometrial cancer. The postoperative diagnosis was endometrial cancer stage 1 or 2 for 89% of the cases in both groups. The mean operating time was 170 min for the laparotomy group compared with 178 min for the laparoscopy group (nonsignificant difference). The estimated intraoperative blood loss was significantly greater in the laparotomy group, and the hospital stay was significantly shorter in the laparoscopy group. CONCLUSIONS: The results show that early endometrial cancer can be treated effectively by laparoscopy. Because of this study's retrospective design, the results should be interpreted with caution. However, the advantages of this method for obese patients are evident. The age and weight of these patients should not be used as a contraindication for laparoscopy.

RESUMEN

Malignant uterine tumours can affect the corpus or the cervix. The endometrial carcinoma with its different histological subtypes counts for most of the malignomas of the uterine body. But the rare category of uterine sarcomas (carcinosarcomas, leiomyosarcomas as well as endometrial stromal sarcomas) also belongs to this group. Cervical cancer presents an own entitity, regarding both histology and therapeutic options. Endometrial cancer is the most common genital malignoma in Northern Europe and North America. Histologically, the endometrial cancer can be subdivided in two groups: type I is hormonal sensitive and well differentiated, type II represents an undifferenciated aggressive tumour with poor prognosis. In general, the patient is elderly. Due to the main symptom - abnormal vaginal bleeding - endometrial cancer is detected in an early stage in about 75% of all patients. First choice in therapy is stage related surgery. Follow-up schemes have not proved yet to improve survival, therefore clear guidelines are missing. National and international groups recommend regular follow-up visits to detect the early vaginal vault relapse which is curable. Cervical cancer is mainly a squamous cell carcinoma and oncogenic Human Papilloma Virus (HPV) associated. Surgery is only indicated up to stage IIA, advanced stages should be treated by radio-chemotherapy. Several studies have shown that follow-up visits can improve survival rates. Intention is the detection of the curable local relapse.

RESUMEN

OBJECTIVES: Lymph node status is an important prognostic factor in patients with squamous cell carcinoma (SCC) of the vulva. Complete inguinofemoral lymph node dissection (ILND) is accompanied by a high morbidity. Sentinel lymph node biopsy (SLNB) was established for less invasive lymph node (LN) staging. The aim of this study was to evaluate safety of SLNB in terms of accuracy and outcome in a clinical routine setting. METHODS: We retrospectively reviewed the data of patients who underwent SLNB and/or ILND for vulvar SCC in the years 1990-2007. Clinical follow-up was evaluated for histological nodal-negative patients with tumor stage T1 or T2. The false negative rate of SLNB was determined in patients who underwent both SLNB and ILND. RESULTS: Preoperative sentinel lymph node (SLN) visualization by scintigraphy was successful in 95% of all patients. SLNB was false negative in 1/45 inguinae (2.2%). All SLN were detected intraoperatively. During the follow-up period (median 24 months for SLNB and 111 months for ILND), no groin recurrences in initially nodal negative patients occurred (n=34, 59 inguinae). Transient lymph edema occurred in 7/18 patients after ILND (39%) and 2/16 patients (13%) after SLNB. No persistent edemas were found after SLNB and ILND. CONCLUSION: According to our experience SLNB is feasible and accurately predicts LN status of vulvar SCC under clinical routine conditions. SLNB in vulvar cancer seems to be a safe alternative to ILND in order to reduce morbidity of surgical treatment.
