Prognostic value of isolated tumor cells in sentinel lymph nodes in low risk endometrial cancer: results from an international multi-institutional study.

OBJECTIVE: The prognostic significance of isolated tumor cells (≤0.2 mm) in sentinel lymph nodes (SLNs) of endometrial cancer patients is still unclear. Our aim was to assess the prognostic value of isolated tumor cells in patients with low risk endometrial cancer who underwent SLN biopsy and did not receive adjuvant therapy. Outcomes were compared with node negative patients. METHODS: Patients with SLNs-isolated tumor cells between 2013 and 2019 were identified from 15 centers worldwide, while SLN negative patients were identified from Mayo Clinic, Rochester, between 2013 and 2018. Only low risk patients (stage IA, endometrioid histology, grade 1 or 2) who did not receive any adjuvant therapy were included. Primary outcomes were recurrence free, non-vaginal recurrence free, and overall survival, evaluated with Kaplan-Meier methods. RESULTS: 494 patients (42 isolated tumor cells and 452 node negative) were included. There were 21 (4.3%) recurrences (5 SLNs-isolated tumor cells, 16 node negative); recurrence was vaginal in six patients (1 isolated tumor cells, 5 node negative), and non-vaginal in 15 (4 isolated tumor cells, 11 node negative). Median follow-up among those without recurrence was 2.3 years (interquartile range (IQR) 1.1-3.0) and 2.6 years (IQR 0.6-4.2) in the SLN-isolated tumor cell and node negative patients, respectively. The presence of SLNs-isolated tumor cells, lymphovascular space invasion, and International Federation of Obstetrics and Gynecology (FIGO) grade 2 were significant risk factors for recurrence on univariate analysis. SLN-isolated tumor cell patients had worse recurrence free survival (p<0.01) and non-vaginal recurrence free survival (p<0.01) compared with node negative patients. Similar results were observed in the subgroup of patients without lymphovascular space invasion (n=480). There was no difference in overall survival between the two cohorts in the full sample and the subset excluding patients with lymphovascular space invasion. CONCLUSIONS: Patients with SLNs-isolated tumor cells and low risk profile, without adjuvant therapy, had a significantly worse recurrence free survival compared with node negative patients with similar risk factors, after adjusting for grade and excluding patients with lymphovascular space invasion. However, the presence of SLNs-isolated tumor cells was not associated with worse overall survival.

Upfront surgery in patients with epithelial ovarian cancer and enlarged supradiaphragmatic lymph nodes associated with comparable to neoadjuvant chemotherapy.

BACKGROUND: There is little data regarding the optimal approach to advanced epithelial ovarian cancer (EOC) with isolated extra-peritoneal disease in the cardiophrenic lymph nodes. This study assessed whether the prognosis and surgical outcomes are affected by the treatment approach among these patients. MATERIAL AND METHODS: This retrospective cohort study included patients with advanced EOC, who were treated 2012-2020. Computed tomography scans were reviewed for disease extent and the presence of enlarged supradiaphragmatic nodes (SDLN). Demographic, clinical and oncologic data were recorded. Characteristics and outcomes of patients with and without enlarged SDLN were evaluated, and outcomes of patients with enlarged SDLN who underwent upfront surgery and neoadjuvant chemotherapy were compared. RESULTS: Among 71 women, 47 (66%) had enlarged supradiaphragmatic lymph nodes. Groups had similar baseline characteristics. Among 47 women who had enlarged SDLN. There was no significant difference in progression free survival among patients who had upfront cytoreduction compared to those who received neoadjuvant chemotherapy. Only one asymptomatic chest recurrence was observed. CONCLUSION: Patients with enlarged SDLN have comparable outcomes with either upfront surgery or neoadjuvant chemotherapy. Moreover, the frequency of chest recurrences in patients presenting with enlarged SDLN is exceedingly low.

Physiological and psychological stress responses to labor and delivery during COVID-19 pandemic: a cohort study.

OBJECTIVE: To evaluate objective (saliva cortisol) and subjective (questionnaire) stress levels during the Coronavirus disease (COVID-19) pandemic compared to before the pandemic and their effects on obstetric and neonatal outcomes. METHODS: This cohort study included 36 women with low-risk, singleton, term deliveries at a tertiary academic center during the COVID-19 pandemic and 49 who delivered before. Physiological stress was evaluated with salivary cortisol measurements, and emotional stress with stress scale questionnaires (0-10) during active and full dilation stages of labor, and 2-min postpartum. Cord blood cortisol and pH were obtained. Delivery mode, complications, and neonatal outcomes were evaluated. RESULTS: Psychological stress was higher for the COVID-19 group compared to controls during full dilation (6.2 ± 3.4 vs. 4.2 ± 3, p = .009). The COVID-19 group had significantly lower cord cortisol levels (7.3 vs. 13.6 mcg/dl, p = .001). No differences were found regarding salivary cortisol level assessments at active, full dilation and 2-min post-delivery (p = .584, p = .254, p = .829, respectively). No differences were found regarding pH < 7.1 (p = .487), 1- and 5-min Apgar scores < 7 (p = .179) and neonatal weight (p = .958). CONCLUSIONS: Women who delivered during COVID-19 pandemic had higher stress levels at full dilation and lower cord cortisol levels, as may be expected after exposure to a chronic stressor.

Predictors of uncommon location of sentinel nodes in endometrial and cervical cancers.

OBJECTIVE: Sentinel node mapping is widely used in the treatment of gynecologic cancers. The current study aimed to identify predictors of uncommon sentinel lymph node (SLN) locations. METHODS: The current study included women who were operated for endometrial or cervical cancer with attempted sentinel lymph node mapping during surgical staging. Data were collected from electronic charts. The pelvis and the external ilia and obturator basins were common node locations. Para-aortic, pre-sacral, common iliac, internal iliac, and parametrial nodes were considered uncommon locations. We conducted analyses stratified according to common, uncommon, and very uncommon (para-aortic, pre-sacral, parametrial) node location sites. RESULTS: A total of 304 women were enrolled in the current study; 15.8% had SLN in uncommon locations and 4.3% had very uncommon node locations. Body mass index (BMI) was a negative predictor for uncommon SLN locations (OR 0.88, p = 0.03). The use of either indocyanine green (ICG) or Tc99 & blue dye was an independent predictor for uncommon SLN locations (OR 8.24, p = 0.006). More recent surgeries and the presence of positive nodes were independent predictors for very uncommon node locations (OR 2.13, p = 0.011, and OR 9.3, p = 0.002, respectively). CONCLUSIONS: BMI, tracer type, surgical year, and positive nodes were independent predictors for uncommon SLN locations. These findings suggest that surgical effort, technique and experience may result in better identification of uncommon SLN locations.

Walking to a better future? Postoperative ambulation after cesarean delivery and complications: A prospective study.

OBJECTIVE: To assess the correlation between maternal mobility after cesarean delivery and postoperative morbidity. METHODS: A prospective study was conducted in a tertiary hospital among patients after cesarean delivery. The women were recruited after surgery and before ambulation. Each participant received an accelerometer and routine instructions for mobilization. The patients were asked to wear the accelerometer constantly. It was collected at discharge. Electronic files were reviewed and patients' outcomes were analyzed. The Mann-Whitney U test was used to compare groups and a receiver operating characteristic curve was calculated for the threshold of number of steps. RESULTS: Data were analyzed for 199 patients, among which 107 (54.4%) deliveries were urgent and 90 (45.6%) were elective. The median number of steps was higher for multiparous women compared to nulliparous women (P = 0.035). Patients who developed complications after discharge walked significantly less during their hospitalization compared to those who did not. There was a trend toward increased risk for in-hospitalization complications among patients who walked less while hospitalized. A threshold of more than 9716 steps per hospitalization was found to be associated with fewer post-discharge complications. CONCLUSION: There is a significant correlation between the extent of ambulation after cesarean delivery and fewer postoperative complications.

Oncologic outcomes of endometrial cancer in patients with low-volume metastasis in the sentinel lymph nodes: An international multi-institutional study.

OBJECTIVE: To assess oncologic outcomes in endometrial cancer patients with low-volume metastasis (LVM) in the sentinel lymph nodes (SLNs). METHODS: Patients with endometrial cancer and SLN-LVM (≤2 mm) from December 3, 2009, to December 31, 2018, were retrospectively identified from 22 centers worldwide. Patients with International Federation of Gynecology and Obstetrics (FIGO) stage IV, adnexal involvement, or unknown adjuvant therapy (ATx) were excluded. RESULTS: Of 247 patients included, 132 had isolated tumor cell (ITC) and 115 had micrometastasis (MM). Overall 4-year recurrence-free survival (RFS) was 77.6% (95% CI, 70.2%-85.9%); median follow-up for patients without recurrence was 29.6 (interquartile range, 19.2-41.5) months. At multivariate analysis, Non-endometrioid (NE) (HR, 5.00; 95% CI, 2.50-9.99; P < .001), lymphovascular space invasion (LVSI) (HR, 3.26; 95% CI, 1.45-7.31; P = .004), and uterine serosal invasion (USI) (HR, 3.70; 95% CI, 1.44-9.54; P = .007) were independent predictors of recurrence. Among 47 endometrioid ITC patients without ATx, 4-year RFS was 82.6% (95% CI, 70.1%-97.2). Considering 18 ITC patients with endometrioid grade 1 disease, without LVSI, USI, or ATx, only 1 had recurrence (median follow-up, 24.8 months). CONCLUSIONS: In patients with SLN-LVM, NE, LVSI, and USI were independent risk factors for recurrence. Patients with any risk factor had poor prognosis, even when receiving ATx. Patients with ITC and grade 1 endometrioid disease (no LVSI/USI) had favorable prognosis, even without ATx. Further analysis (with more patients and longer follow-up) is needed to assess whether ATx can be withheld in this low-risk subgroup.

High grade, advanced, serous ovarian cancer with low serum CA125 levels.

This study compares characteristics of advanced stage, high grade serous ovarian cancer, presenting with high or low serum CA125 level. This was a retrospective cohort of 118 patients with high grade serous ovarian, fallopian tube or primary peritoneal cancer, stages IIIC-IV diagnosed from January 1 1997 through January 9 2017. Patient demographics, tumour characteristics, surgical findings, chemotherapy protocols and clinical outcomes were collected. Three groups were evaluated: group A: 21 patients with CA125 serum level ≤152 U/ml, group B: 97 patients with CA125 serum level >152 U/ml, group C: 43 patients from group B with CA125 serum level >500 U/ml and <1000 U/ml. No significant difference was found between groups regarding age, stage at diagnosis, extent of residual disease or disease volume. More group A patients had surgery as primary treatment compared to groups B and C (p=.003, p=.022, respectively). CA125 level at recurrence was lower in group A as compared to the other groups (162.2 vs. 851.7 and 603.4, p=.003, p=.006). Overall survival and progression-free survival did not differ based on CA125 levels. We conclude that patients with advanced stage, high grade, serous ovarian cancer with low CA125 serum levels had the same clinical outcome as patients with higher levels.Impact StatementWhat is already known on this subject? It is known that CA125 level is a prognostic and predictive factor for epithelial ovarian cancer (EOC) outcome. It is elevated in 80% of the patients and within normal range in only 10% of women with advanced stage EOC. Various studies had addressed the patients with advanced stage serous EOC who had high serum CA125 levels at time of diagnosis. But, no study has addressed the 10% of patients with advanced stage who had low serum CA125 levels at time of diagnosis.What the results of this study add? To the best of our knowledge, this is the first study addressing patients with advanced stage EOC who had low serum CA125 levels at time of diagnosis. According to the results of this study, patients with advanced stage, high grade serous EOC presenting with low serum CA125 levels have similar clinical outcomes as do patients with high serum CA125 levels.What the implications are of these findings for clinical practice and/or further research? Further translational research is encouraged for this group of tumours to identify specific molecular markers that might lead to better understanding and treatment for the disease.

DIO3, the thyroid hormone inactivating enzyme, promotes tumorigenesis and metabolic reprogramming in high grade serous ovarian cancer.

High grade serous ovarian cancer (HGSOC) is the most lethal gynecologic malignancy with a need for better understanding the disease pathogenesis. The biologically active thyroid hormone, T3, is considered a tumor suppressor by promoting cell differentiation and mitochondrial respiration. Tumors evolved a strategy to avoid these anticancer actions by expressing the T3 catabolizing enzyme, Deiodinase type 3 (DIO3). This stimulates cancer proliferation and aerobic glycolysis (Warburg effect). We identified DIO3 expression in HGSOC cell lines, tumor tissues from mice and human patients, fallopian tube (FT) premalignant lesion and secretory cells of normal FT, considered the disease site-of-origin. Stable DIO3 knockdown (DIO3-KD) in HGSOC cells led to increased T3 bioavailability and demonstrated induced apoptosis and attenuated proliferation, migration, colony formation, oncogenic signaling, Warburg effect and tumor growth in mice. Proteomics analysis further indicated alterations in an array of cancer-relevant proteins, the majority of which are involved in tumor suppression and metabolism. Collectively this study establishes the functional role of DIO3 in facilitating tumorigenesis and metabolic reprogramming, and proposes this enzyme as a promising target for inhibition in HGSOC.

Time interval from biopsy to surgery and risk for adjuvant therapy in patients with low-risk endometrial cancer.

OBJECTIVE: Among patients with endometrial cancer, longer wait times to surgery were associated with decreased survival. Although endometrial cancer survival rate is high, about 45% of patients receive adjuvant therapy. The aim of this study was to examine whether a longer interval from diagnosis to surgery is associated with increased need for adjuvant treatment among patients with low-risk endometrial cancer. METHODS: A retrospective cohort study of endometrioid endometrial cancer patients treated with surgery between the years 1999 and 2013 was conducted. Patients with pre-operative histology of hyperplasia, grade 1/2 cancers were included. Patients with stage IV disease were excluded. Demographic, clinicopathologic and surgical parameters were collected and correlation with wait time was evaluated. The risk for adjuvant therapy was in two-week intervals from biopsy to hysterectomy. RESULTS: 468 patients were included in the final cohort. 84.3% had stage I disease and 43.8% patients received adjuvant treatment. Mean time from diagnosis to surgery was 63.88 days (SD 10.3, 31-94). The risk for adjuvant therapy was not increased at any of the time intervals that were examined. CONCLUSION: In low risk endometrial cancer, longer time interval between diagnosis and surgery did not increase the need for adjuvant therapy.

The identification of nuclear αvß3 integrin in ovarian cancer: non-paradigmal localization with cancer promoting actions.

Nuclear translocation of transmembrane proteins was reported in high-grade serous ovarian cancer (HGSOC), a highly aggressive gynecological malignancy. Although the membrane receptor αvß3 integrin is amply expressed in HGSOC and involved in disease progression, its nuclear localization was never demonstrated. Nuclear αvß3 was explored in HGSOC cells (OVCAR3, KURAMOCHI, and JHOS4), nuclear localization signal (NLS) modified ß3 OVCAR3, Chinese hamster ovaries (CHO-K1) and human embryonic kidney (HEK293) before/after transfections with ß3/ß1 integrins. We used the ImageStream technology, Western blots (WB), co immunoprecipitations (Co-IP), confocal immunofluorescence (IF) microscopy, flow cytometry for cell counts and cell cycle, wound healing assays and proteomics analyses. Fresh/archived tumor tissues were collected from nine HGSOC patients and normal ovarian and fallopian tube (FT) tissues from eight nononcological patients and assessed for nuclear αvß3 by WB, confocal IF microscopy and immunohistochemistry (IHC). We identified nuclear αvß3 in HGSOC cells and tissues, but not in normal ovaries and FTs. The nuclear integrin was Tyr 759 phosphorylated and functionally active. Nuclear αvß3 enriched OVCAR3 cells demonstrated induced proliferation and oncogenic signaling, intact colony formation ability and inhibited migration. Proteomics analyses revealed a network of nuclear αvß3-bound proteins, many of which with key cancer-relevant activities. Identification of atypical nuclear localization of the αvß3 integrin in HGSOC challenges the prevalent conception that the setting in which this receptor exerts its pleiotropic actions is exclusively at the cell membrane. This discovery proposes αvß3 moonlighting functions and may improve our understanding of the molecular basis of ovarian cancer pathogenesis.

Induction of labor, and physiological and psychological stress responses as expressed by salivary cortisol: a prospective study.

PURPOSE: To describe patterns of physiological and psychological stress during induced labor and their correlation to obstetrical and neonatal outcomes. METHODS: This prospective, observational study included 167 women, with low-risk, singleton pregnancies, who delivered at term, at a tertiary academic center from 2015 through 2018. Among them, 72 (43%) underwent induction and 95 (57%) had spontaneous labor onset. Physiological stress was evaluated by salivary cortisol measurements and emotional stress by questionnaires (visual analogue stress scale 0-10) during latent phase, active phase and full dilation stages of labor, as well as 2 min and 2 h postpartum. Cord blood cortisol and pH were obtained. Stress patterns were compared between parturients who did or did not undergo induction. Modes of delivery, labor and delivery complications, and early neonatal outcomes were compared. Mothers completed the Hospital Anxiety and Depression Scale. RESULTS: Induced women had lower cortisol concentrations during the latent phase compared to spontaneous onset of labor (p = 0.003), with no differences during active (p = 0.237), full dilation (0.668), 2 min and 2 h after delivery (p = 0.666). Stress scale and Hospital Anxiety and Depression Scale scores were similar between groups. Cord cortisol (p = 0.294), 1-min Apgar score ≤ 7 (p = 0.502) and 5-min Apgar score ≤ 7 (p = 0.37) were similar. All had cord pH > 7. CONCLUSIONS: Induction does not increase stress during labor. Moreover, it might have a positive effect on reducing cortisol during the latent phase. These findings might reassure women who are concerned about induction of labor.

Implementing Personal Mentoring in an Obstetrics and Gynecology Residency Program-3-Year Evaluation.

OBJECTIVE: To empower residents-in-training through personal mentorship from a senior physician who dedicates time and guidance to their personal development and provides professional and emotional support. METHODS: A structured model of personal mentoring for residents was designed and implemented in the Department of Obstetrics & Gynecology. The process was assessed by a special-purpose survey constructed and reviewed by established medical mentors. The survey examined residents' attitudes towards personal aspects associated with their residency. The questionnaires were filled out anonymously before launching and 1 and 3 years after initiating the personal mentoring process. RESULTS: The residents' reports showed a distinct trend of increased positive attitudes towards the personal mentoring throughout the process. The residents reported on an improvement in the mentors' availability to address personal aspects within the mentoring relationship (empathy, emotional support in deliberations, career guidance, etc.). The general satisfaction with the residency program improved as well. CONCLUSIONS: Mentoring is a significant element in a comprehensive, multi-dimensional process. Integrating personal mentoring into a residency program, with the focus on interpersonal relational characteristics as empathy, availability, open communication, and guidance, led to improvements in residents' professional development and skills. They also received optimal support and guidance in their professional careers and personal deliberations.

Ethnic Disparities for Gynecologic Cancers in Israel.

BACKGROUND: Israel's unique population is comprised of two main ethnic groups-Jews (75%) and Arabs (21%), with differing socioeconomic, cultural, and genetic profiles. This study's objective was to evaluate disparities in the incidence, presentation, and outcomes of gynecologic cancers among Israeli women of Arab and Jewish ethnicity. METHODS: Data on the Israeli female population diagnosed with gynecologic cancers during the years 2000-2012 was obtained from the National Cancer Registry and the National Population Registry. Disease incidence rates by ethnic origin were calculated, and the "Segi World standard population" was used for age standardization. Data for Jewish and Arab patients was compared using chi-square test for categorical variables and T test for continuous variables. Survival outcomes were compared using the log-rank test and Cox proportional hazards modeling. RESULTS: Annual ASR (age-standardized rate) for ovarian, cervical, and uterine cancers, are all significantly higher among Israeli women of Jewish ethnicity. Israeli Arab women are diagnosed with cervical cancer at an older age (mean, 60.9 vs 55.9, p < 0.001). Stage distribution for uterine, ovarian, and cervical cancers is similar in both ethnic groups. The age-adjusted hazard ratio for mortality from uterine cancer is significantly lower among Jewish Israeli women compared to Arab Israeli women (HR = 0.67, 95% CI 0.57-0.78, p < 0.0001). During the study period, there was a significant decline in the ASR for ovarian cancer among Jewish Israeli women. The ASR for pre-invasive cervical disease increased significantly in both ethnic groups. CONCLUSIONS: Disparities in gynecological cancer rates, presentations, and outcomes are evident between two major ethnic groups in Israel. Lower cancer incidence rates among Israeli Arab women are likely multifactorial. Uterine cancer outcomes between the two ethnic groups need to be further assessed in order to identify opportunities for improved outcomes among Israeli Arab women.

Placental supernatants' enhancement of the metastatic potential of breast cancer cells: is estrogen receptor (ERα) essential for this phenomenon?

PURPOSE: Pregnancy-associated breast cancer (PABC) is usually diagnosed at an advanced stage in comparison to non-pregnant women. The placenta secretes hormones and cytokines, which affect breast cancer progression. Previously, we demonstrated that human placental secretome facilitates the survival and migration of ERα+ breast cancer cells (BCCL), but pregnant women have a relatively high frequency of ERα-negative tumors. In the current study, we analyzed the effect of placental secretome on ERα-negative BCCL. METHODS: BCCL [MCF-7(estrogen/progesterone receptor positive (ERα+/PR+), ERα reduced MCF-7 (siRNA, MCF-7 ERα-), HS-578 and BT-549 cells (both ER-/PR-)] were exposed to supernatants (collected from first trimester human placental explants and from control BCCL) or to E2 + P4 (estrogen + progesterone) in placental supernatant concentrations and then tested for cell proliferation (number, cell cycle, PCNA), cell-death, cell migration, STAT3 pathway activation and functionality. RESULTS: Silencing ERα in the MCF-7 cells negated the placental supernatant and E2 + P4 enhancement of cell migration (> 130%, p < 0.05), number (> 120%) and survival (~ 130%). However, it had no such effect on MCF-7-ER- migration, which was still elevated in the presence of placental secretome. ER-/PR- BCCL were unaffected by the hormones, but placental secretome significantly elevated their migration (115%), number (140-170%), STAT3 phosphorylation (~ 180%) and BT-549 STAT3 level. These effects were negated by the STAT3 inhibitor. CONCLUSIONS: Placental supernatant facilitates BCCL malignant characteristics by activating ERα in estrogen responsive cells and STAT3 in ERα- BCCL. This indicates a possible mechanism that may underlie PABC's advanced state and suggests STAT3 pathway as a therapeutic target for PABC.

Chemotherapy Toxicity in BRCA Mutation Carriers Undergoing First-Line Platinum-Based Chemotherapy.

OBJECTIVE: BRCA mutations are the most frequent mutations causing homologous recombination defects in epithelial ovarian cancers (EOC). Germline mutation carriers are heterozygous for the mutation and harbor one defective allele in all cells. This has been hypothesized to cause increased susceptibility to DNA damage in healthy cells as well as neoplastic ones. Our objective was to assess chemotherapy-associated toxicities in patients with epithelial ovarian cancer with and without a germline BRCA mutation. MATEIALS AND METHODS: A retrospective cohort study of patients with EOC receiving first-line platinum-based chemotherapy at a single center between 2006 and 2016. Indices of chemotoxicity, including blood counts, transfusion requirements, granulocyte colony-stimulating factor (gCSF) prescriptions, episodes of febrile neutropenia, and treatment delays were compared for BRCA mutation carriers and noncarriers. RESULTS: A total of 90 women met the inclusion criteria, including 31 BRCA mutation carriers (34%) and 59 noncarriers (66%). Mean hemoglobin, neutrophil count, and platelet counts during treatment were comparable for the two patient groups. There was a trend toward a higher frequency of hematological events in BRCA mutation carriers (neutropenia <1500 per mL: 6% vs. 0%, p = .12; thrombocytopenia <100,000 per mL: 23% vs. 9%, p = .07), but these differences were not statistically significant. Similarly, no significant differences were found in surrogates of bone marrow toxicity such as blood transfusions, use of gCSF, episodes of febrile neutropenia, or treatment delays. CONCLUSION: BRCA mutation carriers and noncarriers receiving first-line platinum-based chemotherapy for EOC have similar hematologic toxicity profiles. Clinicians treating these patients can be reassured that chemotherapy dosing or schedule do not require adjustment in patients carrying BRCA mutations. IMPLICATIONS FOR PRACTICE: Patients with ovarian cancer carrying BRCA mutations are more likely to have serous tumors and present with higher CA125 levels. Germline BRCA mutation status is not associated with increased frequency of adverse hematologic events among patients with ovarian cancer being treated with first-line platinum-based chemotherapy. Germline BRCA mutations are also not associated with more treatment delays or a lower number of courses completed in this patient population. These findings should reassure practitioners engaged in care for patients with ovarian cancer that BRCA mutation status most likely will not affect chemotherapy dosing or schedule.

Physiological and psychological stress responses to labor and delivery as expressed by salivary cortisol: a prospective study.

BACKGROUND: Labor is considered a stressful event, yet no study has described the course of stress measured by cortisol during labor and postpartum. OBJECTIVE: The objective of the study was to describe the patterns of physiological and psychological stress during labor as measured by salivary cortisol concentrations and stress questionnaires and their correlation to obstetric and neonatal outcomes. STUDY DESIGN: This prospective, observational study included 167 women with low-risk, singleton, term deliveries at a tertiary academic center. Physiological stress was evaluated by salivary cortisol measurements and emotional stress by questionnaire (stress scale ranging from 0 to 10) during the latent phase, active phase, and full dilation stages of labor as well as 2 minutes, 2 hours, and 24 hours after delivery. Cord blood cortisol and pH were also obtained. Modes of delivery, complications during labor and delivery, and early neonatal outcomes were evaluated. RESULTS: Salivary cortisol concentrations increased gradually from latent phase to active phase. The maximum increase was observed within 2 minutes of the delivery (from an average of 1.06 µg/dL to 1.67 µg/dL; 57% increase). Within 2 hours after delivery, cortisol decreased and reached a nongravid concentration after 24 hours (0.16 µg/dL). Cortisol concentrations during labor and up to 2 hours postpartum were above the average concentration of nongravid women (0.5 µg/dL). Women with epidural anesthesia had lower cortisol concentrations at complete dilation (P = .026) and 2 hours postpartum (P = .016) compared with women without epidural. Psychological stress peaked during latent and full dilation phases (mean 4.56 and 4.29, respectively). Maximum decrease from 4.29 to 2.04 (52%) occurred immediately postpartum. Cord cortisol was higher among women delivered by vacuum extraction compared with spontaneous vaginal delivery (17 ± 2 vs 11 ± 3.8, P = .03). CONCLUSION: This study reveals the course of cortisol concentrations during labor for low-risk pregnancies, with maximum increase immediately postpartum. Subjective stress levels decreased over the course of labor. Salivary cortisol portrays stress during labor and may be used as a reference to evaluate complicated pregnancies and to evaluate the role of cortisol during these deliveries.

Postcoital bleeding is a predictor for cervical dysplasia.

BACKGROUND: Postcoital bleeding (PCB) is a common gynecological symptom that may cause concern among both patients and physicians. Current literature is inconclusive regarding management recommendations. OBJECTIVE: To identify risk-factors for dysplasia/cancer among patients presenting post-coital bleeding (PCB). METHODS: Using large health maintenance organization (HMO) database, all women reporting PCB in 2012-2015 were identified. PCB patient records in a single colposcopy center were reviewed. Age, marital status, ethnicity, gravidity, parity, BMI, smoking, PAP smear result (within 1 year of PCB presentation), colposcopy and biopsy results were recorded. Cases were matched by age and socio-economic enumeration area to controls accessing primary care clinics for routine care. RESULTS: Yearly incidence of PCB ranged from 400 to 900 per 100,000 women; highest among patients aged 26-30 years. Among the sample of 411 PCB cases with colposcopy, 201 (48.9%) had directed biopsy. Biopsy results included 68 cervicitis (33.8%), 61 koilocytosis/CIN 1/condyloma (30.3%), 44 normal tissue (21.9%), 25 cervical polyp (12.4%), 2 CIN 2/3 (1%) and 1 carcinoma (0.5%). Positive predictive value for koilocytosis/CIN 1 or higher pathology was 15.6% (64/411) and 0.7% for CIN 2 or higher grade pathology (3/411). In conditional logistic regression, multiparty was a protective factor: OR 0.39 (95% CI 0.22-0.88, P = 0.02), while pathological PAP smear was a related risk-factor: OR 3.3 (95% CI 1.31-8.35, P = 0.01). When compared to controls, PCB patients were significantly (P = 0.04) more likely to present CIN 1 or higher grade pathology (OR 1.82, 95% CI 1.02-3.33). CONCLUSIONS: Study results indicate that PCB may require colposcopy, especially for nulliparous women with an abnormal PAP smear.

Conservative management for postmenopausal women with tubo-ovarian abscess.

OBJECTIVES: The aim of the study was to describe the experience of one institution in management and outcome of tubo-ovarian abscess (TOA) in pre- and postmenopausal women and to reassess the optimal approach for TOA in postmenopausal women. METHODS: A retrospective cohort study included women diagnosed with TOA between 2003 and 2017 in a tertiary referral center. TOA was diagnosed by sonography or computerized tomography and at least one of the following criteria: temperature more than 38°C, leukocytosis more than 15,000 mm, or surgically proven disease. Women were followed up for a mean of 7.6 years (range 6 mo to 14 y). The rates of conservative management and pelvic malignancy were evaluated. RESULTS: The study cohort included 144 (69.23%) women who met the inclusion criteria, of which 105 (72.92%) were premenopausal and 39 (27.08%) were postmenopausal. Univariate analysis found no differences in risk factors and disease characteristics between the two groups. Among the study sample, 22 (56.4%) postmenopausal women and 48 (45.7%) premenopausal women were treated surgically (P = 0.5). None of the premenopausal women and 1 (2.6%) postmenopausal woman were diagnosed with pelvic malignancy. CONCLUSION: In postmenopausal women with TOA, the prevalence of concurrent pelvic malignancy was 2.6%, which is higher than in the general population, but lower than that reported in the literature; 44% were conservatively managed without any apparent cases of misdiagnoses of cancer.
