Eosinophilic esophagitis: Does age matter?

OBJECTIVES

Eosinophilic esophagitis (EoE) is often diagnosed in school-age children between 6- and 9-year-old. There is less known about those who are diagnosed with EoE that are younger than 6 years old. The objective of this study is to compare clinical presentation, comorbidities, and outcomes based on age at diagnosis of EoE.

METHODS

Single-center retrospective chart review of children (<18 years) diagnosed with EoE between 2005 and 2020. We recorded demographics, clinical presentation, family history, past medical history, treatment, and endoscopic findings. Children in this cohort were classified based on age into three age groups: <2 years, 2-<6 years, and 6-<18 years.

RESULTS

We identified 256 children with EoE, the mean age (SD) at the time of diagnosis was 9 (5.2) years and 184 (72%) were male. We had 164 (64%) patients with available follow-up esophagogastroduodenoscopies (EGD) data (495 EGDs in total) of those 99/164 (60%) reached mucosal remission. In the very young children (<2 years) vomiting was the most common presentation, while poor weight gain was seen more in the 2-<6-year group in comparison to the >6-years. Food impaction and abdominal pain were most likely to present in older children 6-18 years. Combination therapy, as opposed to a single therapy, induced remission at a higher frequency in the <6-year group in comparison to the 6-<18-year group (85% vs. 66%).

CONCLUSION

EoE should be considered in younger children presenting with feeding difficulty and poor weight gain. Combination therapy seems to be more effective in younger children with EoE, but further studies with bigger sample size are needed to study the efficacy of the different combination therapies.

Defining success after surgical treatment of stress urinary incontinence

BACKGROUND

A consensus standardized definition of success after stress urinary incontinence surgical treatment is lacking, which precludes comparisons between studies and affects patient counseling.

OBJECTIVE

This study aimed to identify optimal patient-centric definition(s) of success after stress urinary incontinence surgical treatment and to compare the identified "more accurate" treatment success definitions with a commonly used composite definition of success (ie, no reported urine leakage, negative cough stress test result, and no retreatment).

STUDY DESIGN

We evaluated 51 distinct treatment success definitions for participants enrolled in a previously conducted randomized trial of stress urinary incontinence treatments concomitantly performed with sacrocolpopexy (NCT00934999). For each treatment success definition, we calculated the mean (SD) of participant-assessed symptom improvement and participant-assessed surgical success scores with an 11-point Likert scale among those achieving success and failure. The "more accurate" treatment success definition(s) were identified by measuring the magnitude of the mean difference of participant assessments with Hedges g values. The treatment success definitions with the highest Hedges g values were considered "more accurate" treatment success definitions and were then compared with the composite definition of success.

RESULTS

The percentage of participants who had treatment success (6.4% to 97.3%) and Hedges g values (-4.85 to 1.25) varied greatly according to each treatment success definition. An International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score ≤5, Urogenital Distress Inventory-6 score ≤33.3, and a no/mild stress urinary incontinence response on Urogenital Distress Inventory-6 question 3 had the highest Hedges g values and were considered the top 3 "more accurate" treatment success definitions. Paradoxically, treatment success definitions that required a negative cough stress test result or no persistent urinary leakage greatly reduced the ability to differentiate between participant-assessed symptom improvement and surgical success. When the "more accurate" treatment success definitions were compared with the composite definition, patients with failed treatment according to the composite definition had lower Urinary Impact Questionnaire-7 scores and a higher proportion of survey responses indicating complete satisfaction or some level of satisfaction and very good/perfect bladder condition. In addition, the composite definition had considerably fewer favorable outcomes for participants than did the top 3 "more accurate" treatment success definitions.

CONCLUSION

Successful outcomes of stress urinary incontinence surgical treatments for women undergoing concurrent sacrocolpopexy varied greatly depending on the definition used. However, stringent definitions (requiring complete dryness) and objective testing (negative cough stress test result) had decreased, rather than increased, participant-assessed symptom improvement and surgical success scores. The "more accurate" treatment success definitions better differentiated between participant-assessed symptom improvement and surgical success than the composite definition. The composite definition disproportionately misidentified participants who reported minor symptoms or complete/partial satisfaction with their outcome as having treatment failures and yielded a considerably lower proportion of women who reported favorable outcomes than did the top 3 "more accurate" treatment success definitions.

Risk of Autoimmune Disease in Research-Identified Cases of Autism Spectrum Disorder: A Longitudinal, Population-Based Birth Cohort Study

OBJECTIVE

Determine the risk of autoimmune disease in research-identified cases of autism spectrum disorder (ASD) compared with referents using a longitudinal, population-based birth cohort.

METHODS

ASD incident cases were identified from a population-based birth cohort of 31,220 individuals. Inclusive ASD definition based on DSM-IV-TR autistic disorder, Asperger syndrome, and pervasive developmental disorder, not otherwise specified, was used to determine ASD cases. For each ASD case, 2 age- and sex-matched referents without ASD were identified. Diagnosis codes assigned between birth and December 2017 were electronically obtained. Individuals were classified as having an autoimmune disorder if they had at least 2 diagnosis codes more than 30 days apart. Cox proportional hazards models were fit to estimate the hazard ratio (HR) between ASD status and autoimmune disorder.

RESULTS

Of 1014 ASD cases, 747 (73.7%) were male. Fifty ASD cases and 59 of the 1:2 matched referents were diagnosed with first autoimmune disorder at the median age of 14 and 17.1 years, respectively. ASD cases had increased risk of autoimmune disease compared with matched referents (HR 1.74; 95% confidence interval [CI], 1.21-2.52). The increased risk was statistically significant among male patients (HR 2.01; 95% CI, 1.26-3.21) but not among the smaller number of female subjects (HR 1.38; 95% CI, 0.76-2.50).

CONCLUSION

This study provides evidence from a longitudinal, population-based birth cohort for co-occurrence of ASD and autoimmune disorders. Thus, children with ASD should be monitored for symptoms of autoimmune disease and appropriate workup initiated.

The Association of Adverse Childhood Experiences with Long-term Mood and Anxiety Disorders After Childhood Traumatic Brain Injury: A Population-based Case-Control Study

OBJECTIVE

To assess the association between ACEs and the development of psychiatric disorders by age 25 among individuals who sustained TBI prior to age 10.

DESIGN

Population-based case-control study.

SETTING

Olmsted County, Minnesota.

PARTICIPANTS

566 individuals (N=566) who sustained a TBI prior to age 10 were identified and classified using a validated TBI classification system. Among these individuals, cases with a subsequent mood or anxiety disorder prior to age 25 were identified through clinical diagnostic codes and manual record review. For each case, a 1:1 matched control was randomly selected from individuals with a pediatric TBI who did not have a mood/anxiety disorder prior to the matched case's mood/anxiety disorder.

INTERVENTIONS

Not applicable MAIN OUTCOME MEASURES: Development of a mood/anxiety disorder.

RESULTS

Among the 114 matched pairs of individuals with a TBI prior to age 10, a subsequent mood/anxiety diagnosis was significantly associated with a history of 10 of 14 ACE categories and with having an ACE score ≥1 (odds ratio 5.17; 95% confidence interval 2.78-9.59).

CONCLUSIONS

This is the first population-based study to the authors' knowledge showing that among children who sustained a TBI prior to age 10, those who experienced ACEs are at increased risk of developing a mood or anxiety disorder.

Influence of the COVID-19 pandemic on prenatal and postpartum patient experiences and well-being

BACKGROUND

It has yet to be fully elucidated how differing populations of obstetric patients adapted to the disruptions in perinatal care and postpartum support from the COVID-19 pandemic. We surveyed an enriched sample of socioeconomically advantaged patients to understand the influence of COVID-19 on their perinatal care experience, well-being, and coping.

METHODS

We surveyed pregnant and postpartum patients (n = 6140) at a large academic medical center in the Midwest of the United States using the Coronavirus and Perinatal Experiences instrument in Spring 2021.

RESULTS

The survey was sent to 6141 pregnant and postpartum patients; 1180 (17.8%) respondents completed the survey, including 256 who were pregnant and 834 postpartum. Most pregnant patients experienced no changes in their prenatal care with 16.5% indicating somewhat worsened care. In the postpartum cohort, 37.5% stated their care had somewhat worsened. In describing influences on stress and mental health, 58.1% of postpartum respondents stated it was moderately, and 17.4% significantly, worse. The pandemic had a somewhat or moderately negative influence for 72.7% of respondents, with 11.0% stating these effects were extremely negative. Both cohorts characterized a range of coping strategies, most commonly, talking with friends and family (76.3%).

CONCLUSION(S)

Even among this sample of socioeconomically advantaged patients, respondents indicated that the pandemic disrupted many facets of their medical care and daily life, especially social activities and postpartum support. Our findings suggest that counseling on coping and adaptation strategies for stressors and increased health systems support be part of perinatal care during public health emergencies for all demographic groups.

Effectiveness of Hepatitis B Vaccination for Patients With Inflammatory Bowel and Celiac Disease

BACKGROUND & AIMS

Guidelines recommend measuring antibody (Ab) titers to hepatitis B virus (HBV) after vaccination for patients with inflammatory bowel disease (IBD) or celiac disease (CD) ("patients with IBD/CD") and revaccinating when titers are low. Few data, however, support this recommendation. We aimed to compare effectiveness of HBV vaccination (immunity and infection rates) for patients with IBD/CD vs matched referents.

METHODS

Using the Rochester Epidemiology Project, we performed a retrospective cohort study of patients first diagnosed with IBD/CD (index date) while residing in Olmsted County, Minnesota, from January 1, 2000, through December 31, 2019. HBV screening results were obtained from health records.

RESULTS

In 1264 incident cases of IBD/CD, only 6 HBV infections were diagnosed before the index date. A total of 351 IBD/CD cases had documented receipt of 2 or more HBV vaccines before their index date and had hepatitis B surface antigen Ab (anti-HBs) titers measured after their index date. The proportion of patients with HBV-protective titers (≥10 mIU/mL) decreased with time before plateauing, with protective titer rates of 45% at 5 up to 10 years and 41% at 15 up to 20 years after the last HBV vaccination. The proportion of referents with protective titers also decreased with time and was consistently higher than the levels of patients with IBD/CD within 15 years after the last HBV vaccination. However, no new HBV infection developed in any of 1258 patients with IBD/CD during a median follow-up of 9.4 years (interquartile range, 5.0-14.1 years).

CONCLUSIONS

Routine testing of anti-HBs titers may not be indicated for fully vaccinated patients with IBD/CD. Additional studies are needed to confirm these findings in other settings and populations.

The certified child life specialist: A novel resource in the pediatric primary care clinic for managing children's pain during routine immunizations

This study evaluated the effect of the Certified Child Life Specialist (CCLS) on pediatric pain and pain management during routine immunization administration in the pediatric primary care clinic. Children 4-12 years of age (n = 125) presenting for a well child physical examination at a rural primary care clinic were selected to receive standard nursing care or standard nursing care plus CCLS support during routine immunization administration. Patient reported pain was measured using the Faces Pain Scale-Revised (FPS-R), and patient behavioral responses were measured during immunization administration using the Children's Emotional Manifestation Scale (CEMS). The performance of psychosocial interventions and administration of topical pain-relieving interventions were measured between both groups. CCLS support was associated with fewer negative emotional behaviors during immunization administration among 7- to 12-year-old children and a significantly higher provision of psychosocial interventions and topical pain-relieving interventions among all ages. This study demonstrates that the presence of a CCLS can increase the provision of psychosocial and pain-relieving interventions and reduce distress during immunization administration in a busy pediatric primary care clinic.

Impact of comorbidities and extent of lymphadenectomy on quality of life in endometrial cancer patients treated with minimally invasive surgery in the era of sentinel lymph nodes

OBJECTIVE

To identify predictors of quality of life (QoL) among patients who undergo surgical staging with sentinel lymph node (SLN) biopsy or lymphadenectomy for endometrial cancer.

METHODS

Patients who underwent minimally invasive surgery for primary endometrial cancer at the Mayo Clinic from October 2013 to June 2016 were mailed a 30-item QoL in Cancer survey (QLQ-C30) and a validated 13-item lower extremity lymphedema screening questionnaire. Patients who answered <50% of the items or had a pre-operative history of lymphedema were excluded. Multivariable linear regression models were fit to evaluate predictors of QoL using inverse-probability of treatment weighting to adjust for differences at the time of the surgery between the lymphadenectomy and SLN groups.

RESULTS

The 221 patients included in the analysis were stratified into two groups: patients who underwent (1) bilateral lymphadenectomy as 'backup' after SLN mapping (lymphadenectomy group; n=101) or (2) SLN removal with or without side-specific lymphadenectomy (SLN group; n=120). On multivariable analysis, obesity, lower extremity lymphedema, and kidney disease had significant (p<0.05) and clinically meaningful negative impacts on global QoL. Declines in average adjusted global QoL scores were marked (19.7 points lower) in patients with BMI ≥40 kg/m2 and lower extremity lymphedema compared with non-obese patients without lower extremity lymphedema. In contrast, there was only a 2.9 point difference in the adjusted average global QoL score between the SLN and lymphadenectomy groups.

CONCLUSIONS

Lower extremity lymphedema coupled with obesity predicts poorer QoL in patients who undergo surgical staging for endometrial cancer. In this population, reduction of lower extremity lymphedema by performing SLN instead of lymphadenectomy and earlier targeted interventions may improve patients' QoL. Future research focusing on targeted interventions is needed.

Prognostic factors in patients with endometrial cancer with isolated lymphatic recurrence

OBJECTIVE

To analyze the clinicopathological features and outcomes in patients with endometrial cancer with isolated lymphatic recurrence after lymphadenectomy, stratified by different isolated lymphatic recurrence sites and treatment approaches.

METHODS

We retrospectively reviewed all surgically treated patients with endometrial cancer, identifying those with recurrence. We defined primary isolated lymphatic recurrence as the first and unique evidence of recurrence in lymph node-bearing areas, without concomitant vaginal, hematogenous, or peritoneal recurrence. Isolated lymphatic recurrences were classified as pelvic, para-aortic, distant, or multiple sites. Our primary outcome was cause-specific survival after diagnosis of the recurrence.

RESULTS

Among 4216 patients with surgically staged endometrial cancer, we identified 66 (1.6%) women with isolated lymphatic recurrence. The overall median cause-specific survival for patients with isolated lymphatic recurrence was 24 months. Although cause-specific survival was not significantly different between the four isolated lymphatic recurrence groups (p=0.21), 7 of 15 (47%) patients with isolated lymphatic recurrence in the para-aortic area were long-term survivors. At multivariate Cox regression, the absence of lymphovascular space invasion and grade 1 histology in the primary tumor were significantly associated with improved cause-specific survival. In addition, patients with isolated lymphatic recurrence who underwent surgery for recurrence (with/without other associated therapies) had improved cause-specific survival compared with patients who did not undergo surgery, also after adjusting for age.

CONCLUSIONS

Low-grade histology and absence of lymphovascular space invasion in the primary tumor were predictors of improved prognosis in patients with endometrial cancer with isolated lymphatic recurrence. In addition, in this retrospective cohort, patients with isolated lymphatic recurrence who were selected for eradicative surgical treatment had improved cause-specific survival.

Prognostic stratification of endometrial cancers with high microsatellite instability or no specific molecular profile

Objective

To identify high-risk disease in clinicopathologic low-risk endometrial cancer (EC) with high microsatellite instability (MSI-H) or no specific molecular profile (NSMP) and therapeutic insensitivity in clinicopathologic high-risk MSI-H/NSMP EC.

Methods

We searched The Cancer Genome Atlas for DNA sequencing, RNA expression, and surveillance data regarding MSI-H/NSMP EC. We used a molecular classification system of E2F1 and CCNA2 expression and sequence variations in POLE, PPP2R1A, or FBXW7 (ECPPF) to prognostically stratify MSI-H/NSMP ECs. Clinical outcomes were annotated after integrating ECPPF and sequence variations in homologous recombination (HR) genes.

Results

Data were available for 239 patients with EC, which included 58 MSI-H and 89 NSMP cases. ECPPF effectively stratified MSI-H/NSMP EC into distinct molecular groups with prognostic implications: molecular low risk (MLR), with low CCNA2 and E2F1 expression, and molecular high risk (MHR), with high CCNA2 and E2F1 expression and/or PPP2R1A and/or FBXW7 variants. The 3-year disease-free survival (DFS) rate was 43.8% in the MHR group with clinicopathologic low-risk indicators and 93.9% in the MLR group (P<.001). In the MHR group, wild-type HR genes were present in 28% of cases but in 81% of documented recurrences. The 3-year DFS rate in patients with MSI-H/NSMP EC with clinicopathologic high-risk indicators was significantly higher in the MLR (94.1%) and MHR/HR variant gene (88.9%) groups than in the MHR/HR wild-type gene group (50.3%, P<.001).

Conclusion

ECPPF may resolve prognostic challenges for MSI-H/NSMP EC by identifying occult high-risk disease in EC with clinicopathologic low-risk indicators and therapeutic insensitivity in EC with clinicopathologic high-risk indicators.

Acne incidence in preadolescents and association with increased body mass index: A population-based retrospective cohort study of 643 cases with age- and sex-matched community controls

BACKGROUND/OBJECTIVES

Little is known about acne incidence in preadolescents and its potential association with body mass index (BMI). Our study aims to determine acne incidence in preadolescents and its association with BMI.

METHODS

A population-based retrospective cohort study identified 7- to ≤12 year-olds with an initial acne diagnosis during 2010-2018, and incidence was calculated. Two age- and sex-matched controls without acne were randomly selected per case, and BMI was recorded.

RESULTS

A total of 643 acne patients were identified. Annual age- and sex-adjusted incidence rate was 58.0 per 10,000 person-years, higher in females vs. males (89.2 vs. 28.2 per 10,000 person-years, p < .001), and increased with age (4.3, 24.4, and 144.3 per 10,000 person-years among 7-8, 9-10, and 11-12 year-olds, respectively, p < .001). Systemic medication use was associated with increasing BMI (odds ratio = 1.43 per 5 kg/m2 increase in BMI, 95% CI 1.07-1.92, p = .015). Median BMI percentile was higher among acne cases vs. controls (75.0 vs. 65.0, p < .001), as was the proportion with BMI ≥95th percentile (16.7% vs. 12.2%, p = .01).

CONCLUSION

Acne incidence is higher in preadolescent girls than boys and increases with age. Preadolescents with acne are more likely to be obese than those without acne. Those with higher BMIs are more likely to be given systemic treatment.

Socioeconomic status, race, and preadolescent acne: A population-based retrospective cohort analysis in a mixed rural-urban community of the United States (Olmsted County, Minnesota)

BACKGROUND/OBJECTIVE

There is limited information about the potential relationship of socioeconomic status (SES) with acne in preadolescents. Our objective was to assess the possible relationship between SES and preadolescent acne.

METHODS

A population-based retrospective cohort study was conducted to identify Olmsted County, Minnesota, residents with an initial acne diagnosis between 7 and ≤12 years old during 2010 to 2018 using the Rochester Epidemiology Project. For each acne case, we randomly selected 2 sex- and age-matched controls without an acne diagnosis from the county. Individual HOUsing-based SocioEconomic Status index (HOUSES) derived from real property data was used to evaluate SES, represented as four quartiles with higher quartile representing higher SES.

RESULTS

A total of 604 patients met the criteria. HOUSES distribution significantly differed between cases and controls (p = .001); a higher proportion of acne cases were in quartile 4 (42.2% vs. 32.7%), indicating higher SES. Race and ethnicity did not significantly differ between cases and controls. Among cases and controls, 74.5% and 72.3% were White, respectively. Study limitations include its retrospective design, only patients who visited a physician were included, and Olmsted County residents are largely non-Hispanic White.

CONCLUSION

Preadolescents diagnosed with acne have a higher SES than those without diagnosed acne, highlighting a potential disparity in access to care and appropriate diagnosis.

Long-Term Risk for Mood and Anxiety Disorders After Pediatric Traumatic Brain Injury: A Population-Based, Birth Cohort Analysis

OBJECTIVE

To determine whether exposure to traumatic brain injury (TBI) before 10 years of age is associated with development of a mood or anxiety disorder by 25 years of age, and whether sex or injury severity influences this risk.

SETTING

Olmsted County, Minnesota.

PARTICIPANTS

A total of 5518 persons born from January 1, 1976, through December 31, 1982.

DESIGN

Population-based, birth cohort study. Children sustaining TBI before 10 years of age (index date) were confirmed by manual record review and classified by injury severity using the Mayo Classification System. Each TBI case was age- and sex-matched to 2 referents from the same birth cohort without a history of TBI at the index date. Cox proportional hazards models were fit to compare the risk of a subsequent clinically diagnosed mood or anxiety disorder by 25 years of age between TBI cases and referents. Separate analysis was performed stratified by sex and injury severity.

MAIN MEASURES

Incidence of mood and anxiety disorders determined through clinical diagnostic codes and manual record review.

RESULTS

The study included 562 children (238 females [42.3%] and 324 males [57.7%]) with TBI before 10 years of age (mean [SD] age at TBI: 4.7 [2.8] years). At least 1 mood or anxiety disorder was diagnosed for 115 persons with TBI and 215 referents. No statistically significant association existed between childhood TBI status and anxiety disorder (adjusted hazard ratio [aHR], 1.01 [95% confidence interval (CI), 0.71-1.43]; P = .97) or mood disorder (aHR, 1.16 [95% CI, 0.92-1.47]; P = .21). However, females who sustained TBI had a significantly increased risk of a subsequently diagnosed mood disorder compared with age-matched female referents (aHR, 1.40 [95% CI, 1.04-1.89]; P = .03).

CONCLUSIONS

This study suggests that isolated TBI before 10 years of age is not significantly associated with an increased risk of anxiety or mood disorder by 25 years of age, though females may be at an increased risk.

Use of the Revised Second Victim Experience and Support Tool to Examine Second Victim Experiences of Respiratory Therapists

BACKGROUND

Respiratory therapists (RTs) work alongside allied health staff, nurses, and physicians during stressful and traumatic events that can be associated with emotional and physiological implications known as second victim (SV) experiences (SVEs). This study aimed to evaluate SVEs of RTs, including both positive and negative implications.

METHODS

RTs within a large academic health care organization across Minnesota, Wisconsin, Florida, and Arizona were asked to participate in an anonymous survey that included the validated Second Victim Experience and Support Tool-Revised to assess SVEs as well as desired support services.

RESULTS

Of the RTs invited to participate, 30.8% (171/555) completed the survey. Of the 171 survey respondents, 91.2% (156) reported that they had been part of a stressful or traumatic work-related event as an RT, student, or department support staff member. Emotional or physiologic implications experienced by respondents as SVs included anxiety 39.1% (61/156), reliving of the event 36.5% (57/156), sleeplessness 32.1% (50/156), and guilt 28.2% (44/156). Following a stressful clinical event, 14.8% (22/149) experienced psychological distress, 14.2% (21/148) experienced physical distress, 17.7% (26/147) indicated lack of institutional support, and 15.6% (23/147) indicated turnover intentions. Enhanced resilience and growth were reported by 9.5% (14/147). Clinical and non-clinical events were reported as possible triggers for SVEs. Nearly half of respondents 49.4% (77/156) indicated feeling like an SV due to events related to COVID-19. Peer support was the highest ranked form of desired support following an SVE by 57.7% (90/156).

CONCLUSIONS

RTs are involved in stressful or traumatic clinical events, resulting in psychological/physical distress and turnover intentions. The COVID-19 pandemic has had a significant impact on RTs' SVEs, highlighting the importance of addressing the SV phenomenon among this population.

Comparison of the Contracted Accordion, Expanded Accordion, and Clavien-Dindo complication grading scales after ovarian cancer cytoreduction

OBJECTIVE

To compare the ability of current complication reporting scales (Contracted Accordion Scale, Expanded Accordion Scale, Clavien-Dindo Scale) to reflect the severity of patient outcomes after cytoreductive surgery for ovarian cancer.

METHODS

We included all patients undergoing primary debulking surgery for stage IIIC/IV ovarian cancer from 2006 to 2016 at two expert centers for ovarian cancer. Complications within 30 days of surgery were graded according to three scales. Outcomes included length of stay, mortality (90-day), and delayed initiation of chemotherapy (>42 days after surgery). Correlations were assessed using the Spearman rank correlation, and comparisons between groups were evaluated using the Wilcoxon rank-sum test and the χ² test.

RESULTS

Among the 892 patients, 185 (20.7%) patients had a grade 3 or higher complication per all scales. Patients with grade 3 or higher complications (compared with those with none, grade 1 or grade 2) had longer length of stay, higher 90-day mortality, and delayed initiation of chemotherapy. The expanded scales (Expanded Accordion Scale and Clavien Dindo Scale) provided a more refined characterization of outcome compared with the Contracted Accordion Scale. However, mortality was actually found to be as high as 25.0% for grade 5 complications using the Expanded Accordion Scale. Patients with organ failure or requiring an invasive procedure had significantly worse outcomes than those without either complication, highlighting the importance of separating these events.

CONCLUSIONS

All three scales demonstrated general correlation with important outcomes after ovarian cancer surgery. However, the expanded scales (Clavien Dindo Scale and Expanded Accordion Scale) used important events commonly encountered after cytoreductive surgery, provided a more refined view of the severity of complications, and should be used in reporting outcomes in ovarian cancer.

Contemporary Early Postoperative Cone Repair Outcomes for Patients With Ebstein Anomaly

OBJECTIVE

To describe the early postoperative outcomes after cone repair (CR) for Ebstein anomaly (EA) across the age spectrum.

PATIENTS AND METHODS

For this study, 284 patients from 1 to 73 years of age who underwent CR at Mayo Clinic from June 1, 2007, to December 21, 2018, were separated by age group (1-<4, 4-<19, 19-<40, and 40+ years) and by disease severity for analysis. Outcomes of interest included death, reoperation, readmission, early postoperative complications, cardiac intensive care unit and hospital length of stay, and need for superior cavopulmonary anastomosis.

RESULTS

Mortality within 30 days was 0%. The reoperation rate was 4.9% (n=14) and the median hospital length of stay was 5 days, with no statistical difference between ages at time of CR or severity groups. The readmission rate was 2% (n=6). Postoperative complications were seen in 8.8% (n=25) of cases overall, with higher rates in the youngest age group (21%, P<.001). Superior cavopulmonary anastomosis was most common in the youngest age group (37% vs 17% overall, P<.001) and in those with severe disease (35%, P<.001).

CONCLUSION

Children and adults with Ebstein anomaly have very good early postoperative outcomes with a less than 10% complication and reoperation rate and very low mortality following cone reconstruction. In the setting of good and stable right ventricle function and no symptoms of heart failure or cyanosis, waiting for CR until 4 years of age may minimize early postoperative complications and need for superior cavopulmonary anastomosis.

Impact of asymptomatic and mild COVID-19 infection on fetal growth during pregnancy

BACKGROUND

During pregnancy, certain viral infections are known to significantly affect fetal development. Data regarding the impact of COVID-19 viral infection in pregnancy, specifically in asymptomatic or mild cases, remains limited. This presents a challenge in providing prenatal counseling and antepartum surveillance in pregnancies complicated by COVID-19 infection. Placenta studies have demonstrated that vascular malperfusion patterns attributed to COVID-19 appear to depend on the timing of infection. Given these placental changes, we aim to evaluate the impact of COVID-19 on fetal growth in pregnant patients with asymptomatic or mild disease, stratified by trimester of infection. We hypothesize that COVID-19 infection, especially early in pregnancy, increases the risk of fetal growth restriction (FGR).

STUDY DESIGN

This is a single institution, retrospective cohort study of patients ages 16-55 years old with a singleton delivery between December 10, 2020, and April 19, 2021 who had not received a COVID-19 vaccination prior to delivery. COVID-19 infection during pregnancy was defined as a positive SARS-CoV-2 RT-PCR test. FGR was defined as an estimated fetal weight less than the 10th percentile for gestational age or abdominal circumference less than the 10th percentile for gestational age. Maternal and fetal characteristics, including FGR, were compared between women with versus without COVID-19 infection during pregnancy.

RESULTS

Among 1971 women with a singleton delivery, 208 (10.6 %) had a prior asymptomatic or mild COVID-19 infection during pregnancy. With the exception in the median prenatal BMI being significantly higher in the COVID-19 group (median, 27.5 vs 26.3, p = 0.04), there were no significant differences in demographics, baseline maternal comorbidities or gestational age between those with versus without COVID-19 infection during pregnancy, or in the proportion of their offspring with FGR (3.4 % (7/208) vs 4.8 % (84/1763), p = 0.36). When the 208 women were stratified by the timing of their COVID-19 infection, the proportion with an offspring with FGR was 8.7 % (2/23), 1.2 % (1/84), and 4.0 % (4/101), for those first diagnosed with COVID-19 during the 1st, 2nd, and 3rd trimesters, respectively (p = 0.72 Cochran-Armitage test for trend).

CONCLUSION

Asymptomatic or mild COVID-19 infection in pregnancy, regardless of timing of infection, does not appear to be associated with FGR. Routine serial fetal growth assessment may not be warranted solely for history of COVID-19 infection.

Validation of a risk-based algorithm to reduce poor operative outcomes after complex surgery for ovarian cancer

OBJECTIVE

We developed an algorithm that identifies patients at high risk of morbidity/mortality after cytoreductive surgery for advanced ovarian cancer. We have previously shown that the Mayo triage algorithm reduces operative mortality internally, followed by validation using an external low complexity national dataset. However, validation in a higher complexity surgical setting is required before widespread acceptance of this approach, and this was the goal of our study.

METHODS

We included patients who underwent debulking surgery (including primary or interval debulking surgery) for stage IIIC/IV ovarian cancer between October 2011 and November 2019 (SCORPION trial patients until May 2016 and non-trial patients thereafter) at Fondazione Policlinico A Gemelli, Italy. Using the algorithm, we classified patients as either high-risk or triage-appropriate and compared 30-day grade 3+ complications and 90-day mortality using a χ2 test or Fisher's exact test.

RESULTS

A total of 625 patients were included. The mean age was 58.7±11.4 years, 73.6% (n=460) were stage IIIC, and 63.0% (n=394) underwent primary debulking surgery. Surgical complexity was intermediate or high in 82.6% (n=516) of patients (95.7% (n=377) for primary surgery and 60.2% (n=139) for interval surgery), and 20.3% (n=127) were classified as high-risk. When compared with triage-appropriate patients, high-risk patients had (1) a threefold higher rate of 90-day mortality (6.3% vs 2.0%, p=0.02); (2) a higher likelihood of 90-day mortality following a grade 3+ complication (25.9% vs 10.0%, p=0.05); and (3) comparable rates of grade 3+ complications (21.3% vs 16.1%, p=0.17).

CONCLUSION

The evidence-based triage algorithm identifies patients at high risk of morbidity/mortality after cytoreductive surgery. Triage high-risk patients are poor candidates for surgery when complex surgery is required. This algorithm has been validated in heterogeneous settings (internal, national, and international) and degree of surgical complexity. Risk-based decision making should be standard of care when planning surgery for patients with advanced ovarian cancer, whether primary or interval surgery.

Abdominal and robotic sacrocolpopexy costs following implementation of enhanced recovery after surgery

OBJECTIVE

To compare perioperative costs and morbidity between open and robotic sacrocolpopexy after implementation of enhanced recovery after surgery (ERAS) pathway.

METHODS

The present retrospective cohort study of patients undergoing open or robotic sacrocolpopexy (January 1, 2014, through November 30, 2017) used an ERAS protocol with liposomal bupivacaine infiltration of laparotomy incisions. Primary outcomes were costs associated with index surgery and hospitalization, determined with Medicare cost-to-charge ratios and reimbursement rates and adjusted for variables expected to impact costs. Secondary outcomes included narcotic use, length of stay (LOS), and complications from index hospitalization to postoperative day 30.

RESULTS

For the total of 231 patients (open cohort, 90; robotic cohort, 141), the adjusted mean cost of robotic surgery was $3239 higher compared with open sacrocolpopexy (95% confidence interval [CI] $1331-$5147; P < 0.001). Rates were not significantly different for intraoperative complications (robotic, 4.3% [6/141]; open, 5.6% [5/90]; P = 0.754), 30-day postoperative complications (robotic, 11.4% [16/141]; open, 16.7% [15/90]; P = 0.322), or readmissions (robotic, 5.7% [8/141]; open, 3.3% [3/90]; P = 0.535). The percentage of patients dismissed on postoperative day 1 was greater in the robotic group (89.4% [126/141] vs. 48.9% [44/90], P < 0.001).

CONCLUSIONS

Decreased LOS associated with ERAS provided significant cost savings with open sacrocolpopexy versus robotic sacrocolpopexy without adverse impacts on perioperative complications or readmissions.

Changing Trends of Invasive Pneumococcal Disease in the Era of Conjugate Pneumococcal Vaccination in Olmsted County: A Population-Based Study

OBJECTIVE

To estimate the incidence of invasive pneumococcal disease (IPD) in the pre-13-valent pneumococcal conjugate vaccine (pre-PCV13; 7-valent pneumococcal conjugate vaccine era, 2002-2010) and post-PCV13 (2011-2018) time periods.

PATIENTS AND METHODS

Using the Rochester Epidemiology Project, we conducted a population-based cohort study of all IPD cases in Olmsted County, Minnesota, from January 1, 2002, to December 31, 2018.

RESULTS

Overall, 187 cases of IPD were identified. The incidence of IPD decreased significantly from 11.1 (95% CI, 9.1 to 13.2) to 5.6 (95% CI, 4.3 to 6.9) per 100,000 person-years when the pre- and post-PCV13 periods (2002-2010 vs 2011-2018) were compared (P<.001). Of the 187 patients with IPD, 112 (59.9%) had previously received at least 1 dose of pneumococcal vaccine. Among the IPD cases in the post-PCV13 period, there was an increase in non-PCV13 serotypes, mainly 11A (from 1.0% [1 of 105] to 6.2% [4 of 64]) and 33F (from 2.9% [3 of 105] to 15.6% [10 of 64]), while PCV13/non-7-valent pneumococcal conjugate vaccine serotypes declined from 38.1% (40 of 105) to 15.6% (10 of 64). At 30 days after an IPD diagnosis, the survival rate was 88.8% (95% CI, 84.4% to 93.4%).

CONCLUSION

A marked decline in IPD incidence occurred during the post-PCV13 era. Because of the observed increase in non-PCV13 serotypes, coupled with multiple factors that impact the epidemiology of IPD, ongoing surveillance of patients with IPD, particularly due to non-PCV13 serotypes, is warranted.

Not all stage I and II endometrial cancers are created equal: Recurrence-free survival and cause-specific survival after observation or vaginal brachytherapy alone in all subgroups of early-stage high-intermediate and high-risk endometrial cancer

OBJECTIVE

To evaluate recurrence-free survival (RFS) and cause-specific survival (CSS) after observation or vaginal brachytherapy (VB) alone in all subgroups of early-stage high-intermediate (HIR) and high-risk endometrial cancer (EC).

METHODS

We identified patients with stage I HIR (GOG-249 criteria) and stage II endometrioid EC, and stage I and II non-endometrioid EC who underwent surgery at Mayo Clinic and Cleveland Clinic between 1999 and 2016. Three-year RFS and CSS after observation or VB only were estimated in 16 subgroups defined by risk factors.

RESULTS

Among 4156 ECs, we identified 447 (10.8%) stage I endometrioid HIR, 52 (1.3%) stage II endometrioid, 350 (8.4%) stage I non-endometrioid, and 17 (0.4%) stage II non-endometrioid ECs; observation or VB alone was applied in 349 (78.1%), 24 (46.2%), 187 (53.4%), and 2 (11.8%) patients, respectively. After observation or VB, stage I HIR endometrioid EC subgroups with <2 factors among grade 3, LVSI, or stage IB had a 3-year CSS >95% (lower 95% confidence intervals limit: 89.8%), whereas subgroups with ≥2 factors had poorer outcomes. No EC-related deaths after 3 years were reported in 97 stage IA non-endometrioid ECs without myometrial invasion. Stage II ECs had poor outcomes regardless of histology.

CONCLUSIONS

Observation or VB only may be sufficient in stage I endometrioid HIR ECs with <2 factors among grade 3, LVSI, or IB and in stage IA non-endometrioid ECs without myometrial invasion. Stratification of early-stage HIR and high-risk ECs into risk subgroups potentially alleviates the overtreatment and undertreatment risk and should be considered in future research.

Women With a History of Primary Infertility and Increased Rates of Bilateral Oophorectomy

OBJECTIVE

To evaluate the association of primary infertility with subsequent bilateral oophorectomy and hysterectomy, using a population-based cohort of women with primary infertility and age-matched women in a referent group.

METHODS

The Rochester Epidemiology Project record-linkage system was used to assemble a population-based cohort of women with primary infertility diagnosed between 1980 and 1999 (index date). Women were age-matched (±1 year) 1:1 to women without a history of infertility or hysterectomy at the index date (referent group). Cox proportional hazards models were fit to compare long-term risks of bilateral oophorectomy and hysterectomy, respectively, between women with infertility and women in the referent group.

RESULTS

Among both groups of 1,001 women, the mean age at the index date was 29.2±4.4 years. Median duration of follow-up was 23.7 years for both groups. Women with primary infertility were 1.7 times (adjusted hazard ratio [aHR] 1.69, 95% CI 1.22-2.33) more likely to undergo bilateral oophorectomy compared with women in the referent group. In a sensitivity analysis that excluded women with a diagnosis of infertility related to endometriosis and their matched referent group participants, this association persisted (aHR 1.50, 95% CI 1.06-2.14). Women with primary infertility did not have a significant increased risk of hysterectomy (aHR 0.98, 95% CI 0.79-1.23). However, risk of hysterectomy was increased in those with primary infertility related to endometriosis (aHR 1.94, 95% CI 1.12-3.34). We observed that women with primary infertility were more likely to undergo hysterectomy with bilateral oophorectomy. Women in the referent group were more likely to undergo hysterectomy with ovarian conservation. Few women in either group had isolated bilateral oophorectomy.

CONCLUSION

Primary infertility, with and without a diagnosis of endometriosis, is associated with an increased risk of bilateral oophorectomy. In women with endometriosis-related infertility, there is an association with future hysterectomy. These findings represent important confounders in the evaluation of long-term health outcomes related to primary infertility.

Long-term risk of death in patients with hidradenitis suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is associated with substantial morbidity. Few studies have addressed the natural history and mortality rates associated with HS. A higher risk of cardiovascular death in patients with HS has been reported. We investigated whether patients with HS have an increased overall risk of death compared with age- and gender-matched referents.

METHODS

We performed a retrospective cohort study of residents of Olmsted County, Minnesota, with incident HS between January 1, 1980, and December 31, 2008, and age- and gender-matched referents. The main outcomes and measures were the overall and cause-specific risks of death.

RESULTS

We identified 226 incident cases of HS and 678 age- and gender-matched referents among Olmsted County residents during the study period. Compared to referents, patients with HS had a significantly higher risk of all-cause death (hazard ratio [HR, 2.48; 95% CI, 1.53-4.03, P < 0.001) and cardiovascular- or cerebrovascular-related death (HR, 2.85; 95% CI, 1.10-7.40, P = 0.03). However, these risks were attenuated by adjusting for smoking history: all-cause HR, 1.65 (95% CI, 0.97-2.82, P = 0.07) and cardiovascular- or cerebrovascular-related HR, 2.03 (95% CI, 0.71-5.81, P = 0.18). The 71% of patients were former or current smokers at the time of HS diagnosis.

CONCLUSIONS

Hidradenitis suppurativa patients have a substantially increased risk of death from any cause, including cardiovascular or cerebrovascular causes; the risk is especially dependent on smoking history.

Association of tumor molecular factors with in-transit metastasis in primary cutaneous melanoma

BACKGROUND

In-transit metastases (ITM) are a form of locoregional relapse representing intralymphatic metastatic spread and occur in approximately 4-9% of patients with melanoma >1 mm Breslow thickness. Our objective was to evaluate a combination of clinicopathologic risk factors and gene expression biomarkers predictive of ITM risk.

METHODS

We used PCR to quantify gene expression in diagnostic biopsy tissue across a prospectively designed archival cohort of 854 consecutive thin and intermediate thickness primary cutaneous melanomas. The outcome of interest was ITM >90 days after a melanoma diagnosis. Cox proportional hazard models were fit to estimate each clinicopathologic and molecular characteristic's association with the risk of ITM.

RESULTS

The 5-year cumulative incidence of ITM was 3.2%. Clinical factors univariately associated with an increased risk of ITM were older age, greater Breslow thickness, greater mitotic rate, lower extremity location, ulceration, and a positive SLN biopsy. Of 108 genes tested, five were significantly upregulated and five significantly downregulated when evaluated in Cox models adjusted for age, Breslow thickness, mitotic rate, and lower extremity location. Among the upregulated genes, the strongest association was observed for interleukin-8 (IL8).

CONCLUSION

A subset of gene expression biomarkers was identified as independently associated with the risk of ITM after adjusting for key covariates. Once sufficiently validated, our results may lead the way to regional therapy trials for a small, selected group of high-risk patients.

Family Use of Remote Infant Viewing in the Neonatal Intensive Care Unit: Impact of the COVID-19 Pandemic and Patient Room Type

Background: Remote infant viewing (RIV) uses a bedside camera to allow families to view a livestream video of their neonate 24/7 from anywhere with internet access. Objective: The aim of this study was to evaluate family use of RIV for infants in the neonatal intensive care unit (NICU) during the COVID-19 pandemic and whether RIV use varied by patient room type. Study Design: Use of RIV was evaluated for NICU patients between October 1, 2019, and March 31, 2021. The date, time, and duration of every RIV were exported from the RIV database and linked to the patient's room type. Results: Among 980 patients, 721 (73.6%) were viewed using RIV. The median (interquartile range) number of views per patient-days was 12.5 (5.4-26.0). Based on monthly aggregate data, the proportion of patients with at least one RIV increased during the pandemic from 71.6% in April 2020 to 94.3% in March 2021 (p < 0.001). The monthly number of views and view duration per patient-days also increased (p = 0.003; p = 0.029, respectively). When evaluating patient-level data by room type, the median number of views per patient-days was higher for open-bay than single-family rooms (13.5 vs. 10.5; p < 0.001) and median view duration (minutes) per patient-days was longer (21.8 vs. 12.1; p < 0.001). Conclusions: Use of RIV in the NICU increased during the COVID-19 pandemic. RIV was used more frequently and for longer duration by families with newborns in an open-bay room. RIV allows families to observe their newborn when visitor restrictions are in place or when in-person visits may be less private or do not allow for physical distancing.

Quality is more important than quantity: pre-operative sarcopenia is associated with poor survival in advanced ovarian cancer

BACKGROUND

Sarcopenia is prevalent among older patients with cancer and is associated with poor outcomes.

OBJECTIVE

To explore the relationship between muscle mass, quality, and patient age with overall survival after surgery for advanced ovarian cancer.

METHODS

Patients with advanced stage (IIIC/IV) ovarian cancer who underwent primary cytoreductive surgery between January 2006 and July 2016 were included. Body composition measures were calculated from pre-operative CT imaging: skeletal muscle index (skeletal muscle index=skeletal muscle area normalized for height), skeletal muscle density, and skeletal muscle gauge (product of skeletal muscle index and skeletal muscle density). Each measure was transformed to a z-score and evaluated for association with risk of death using Cox proportional hazards models. Recursive partitioning was used to classify patients into homogeneous subgroups considering age and skeletal muscle gauge as predictors of overall survival.

RESULTS

The study included 429 patients (mean age 64.2 years). Increased age moderately correlated with decreased skeletal muscle gauge (r=-0.45). Decreasing skeletal muscle density and skeletal muscle gauge were significantly associated with increased risk of death; HR (95% CI) per 1-unit decrease in z-score of 1.24 (1.10 to 1.39) for skeletal muscle density and 1.27 (1.12 to 1.44) for skeletal muscle gauge. Associations were diluted after adjusting for age (1.13 (1.00 to 1.29) skeletal muscle density and 1.14 (0.99 to 1.30) skeletal muscle gauge). Recursive partitioning identified three subgroups: <60 years old, ≥60 years old with skeletal muscle gauge ≥937.3, and ≥60 years old with skeletal muscle gauge <937.3; median overall survival was 5.8, 3.3, and 2.3 years, respectively (p<0.001).

CONCLUSIONS

Skeletal muscle gauge, a novel sarcopenia measure incorporating quantity and quality, was associated with poorer survival in patients with advanced ovarian cancer, particularly among patients older than 60. Expanding our knowledge of how sarcopenia relates to solid tumor outcomes among high-risk patients can modify our treatment approach.

Risk factors for development of long-term mood and anxiety disorder after pediatric traumatic brain injury: a population-based, birth cohort analysis

OBJECTIVES

The objective of this study was to identify characteristics associated with an increased risk of anxiety and mood disorder prior to 25 years of age, in children who sustained a traumatic brain injury (TBI) prior to age 10.

METHODS

This population-based study identified 562 TBI cases from a 1976-1982 birth cohort in Olmsted County, Minnesota. TBI cases were manually confirmed and classified by injury severity. Separate Cox proportional hazards regression models were fit to estimate the association of TBI and secondary non-TBI related characteristics with the risk of a subsequent clinically determined anxiety or mood disorder. Multivariable-adjusted population attributable risk (PAR) estimates were calculated for TBI characteristics.

RESULTS

Older age at initial TBI and extracranial injury at time of initial TBI were significantly associated with an increased risk of anxiety (adjusted HR [95% CI]: 1.33 [1.16, 1.52] per 1-year increase and 2.41 [1.26, 4.59]), respectively. Older age at initial TBI was significantly associated with an increased risk of a mood disorder (adjusted HR 1.17 [1.08-1.27]).

CONCLUSION

In individuals sustaining a TBI prior to age 10, age at injury greater than 5 years old was the largest contributor to development of a mood or anxiety disorder.

Impact of enhanced recovery implementation in women undergoing abdominal sacrocolpopexy

OBJECTIVE

To assess the effect of Enhanced Recovery After Surgery (ERAS) with and without liposomal bupivacaine (LB) on opioid use, hospital length of stay (LOS), costs, and morbidity of women undergoing sacrocolpopexy.

METHODS

Retrospective cohort of women who underwent abdominal sacrocolpopexy between April 1, 2009 and November 30, 2017. Costs for relevant healthcare services were determined by assigning 2017 charges multiplied by 2017 Medicare Cost Report's cost to charge ratios. Outcomes were compared among periods with multivariable regression models adjusted for age, American Society of Anesthesiologists score, and concurrent hysterectomy and posterior repair.

RESULTS

Patients were subdivided into pre-ERAS (G1, n = 128), post-ERAS (G2, n = 83), and post-ERAS plus LB (G3, n = 91). The proportion of patients needing opioids during postoperative days 0-2 was significantly less for G3 (75.8%) compared with G1 (97.7%) and G2 (92.8%); P < 0.001). The median morphine equivalent units (MEU) with interquartile ranges, mean LOS, and adjusted mean standardized costs were significantly lower in G3 compared with the other two groups (35 [20-75] vs. 67 [31-109], and 60 [30-122] MEUs; 1.8 vs. 2.3 vs. 2.9 days; and $2391, $2975, and $3844, for G3, G2, and G1, respectively; P < 0.001).

CONCLUSION

Implementation of an ERAS pathway led to significant decreases in opioid use, LOS, and costs. Supplementation with LB further improved these measures.

Down Syndrome Cures: Perspectives of People With Down Syndrome and Their Parents

Down syndrome (DS) research is advancing rapidly, yet efforts have raised ethical questions. This mixed methods study describes views of people with DS (self-advocates) and their parents regarding medical interventions for DS. Responses from 35/171 (20.5%) self-advocates and 430/867 (49.6%) parents showed the majority of self-advocates were glad they have DS (27/35; 77.1%) and liked who they are (33/35; 94.3%), but did want to learn faster (23/35; 65.7%). Parents much more commonly agreed with a willingness to give medications to prevent Alzheimer's disease (427/429; 99.5%) or blood cancer (428/430; 99.5%) as compared with a medicine to cure DS (225/425; 52.9%). Qualitative comments intertwined DS with identity, yet indicated desire for improved quality of life and opportunities. Responses decoupled DS itself from the complications of DS, with treatment of complications being more acceptable.

Understanding the Second Victim Experience Among Multidisciplinary Providers in Obstetrics and Gynecology

OBJECTIVE

The aim of the study was to determine the prevalence of second victim experience (SVE) among obstetrics and gynecology (OBGYN) clinical and nonclinical healthcare workers and compare healthcare workers who did and did not identify as a second victim (SV) in the last year.

METHODS

The validated Second Victim Experience and Support Tool and additional questions designed to explore SVE topics specific to OBGYN healthcare workers were administered to a multidisciplinary group.

RESULTS

Of 571 individuals sent a survey link, 205 completed the survey: 117 worked in obstetrics (OB), 73 in gynecology (GYN), and 15 in both areas. Overall, 44.8% of respondents identified as an SV sometime during their career, 18.8% within the last 12 months. Among nonclinical staff respondents, 26.7% identified as an SV during their career and 13.3% in the last 12 months. Respondents who identified as an SV in the last 12 months reported experiencing significantly more psychological and physical distress, a greater degree to which colleague and institutional support were perceived as inadequate, decreased professional self-efficacy, and increased turnover intentions. The most common events identified as likely triggers for SVE were fetal or neonatal loss (72.7%) and maternal death (68.2%) in OB and patient accusations or complaints (69.3%) in GYN.

CONCLUSIONS

Among survey respondents, there was a high prevalence of SVs in OBGYN staff, distributed equally between OB and GYN. Nonclinical healthcare workers also identified as SVs. The OBGYN departments should consider using the Second Victim Experience and Support Tool to screen for potential SV among their healthcare workers to provide additional support after events.

Children With ADHD Are at Risk for a Broad Array of Adverse Adult Outcomes That Cross Functional Domains: Results From a Population-Based Birth Cohort Study

OBJECTIVE

To identify patterns ("classes") of outcomes for adults with and without childhood ADHD.

METHOD

Subjects were 232 childhood ADHD cases and 335 non-ADHD referents from a 1976 to 1982 birth cohort. We used latent class analyses to identify classes based on a broad array of adult psychosocial outcomes and determined the proportion of subjects with childhood ADHD within each class.

RESULTS

A three class solution provided optimal model fit; classes were termed "good," "intermediate," and "poor" functioning. Subjects with childhood ADHD comprised 62.8% of the "poor," 53.5% of the "intermediate," and 24.9% of the "good" functioning class. The "poor" functioning class was distinguished by increased likelihood of legal trouble and substance use disorders and included more individuals with childhood ADHD and psychiatric disorder than the "intermediate" class (45.5% vs. 30.6%).

CONCLUSION

Children with ADHD are at risk for adverse adult outcomes in multiple domains and co-morbid childhood psychiatric disorders increase risk.

Population-based incidence of food allergies in Olmsted County over 17 years

Background: There is growing concern about the rising incidence and prevalence of food allergy globally. We previously reported the incidence of food allergy in Olmsted County, Minnesota, between 2002 and 2011. We sought to update the incidence and temporal trends of food allergies in our region through 2018. Methods: By using the Rochester Epidemiology Project, all Olmsted County residents, with an incident diagnosis of food allergy between January 2, 2012, and December 31, 2018, were identified and their medical records were reviewed. These cases were combined with the previously collected incidence cases from January 2, 2002, and December 31, 2011, to understand longitudinal trends in food allergy incidence rates. Results: Over the 17-year study period, 1076 patients (58.0% male patients, 72.1% white) were diagnosed with an incident food allergy. The median (interquartile range) age at first diagnosis was 2.0 years (1.1-8.4 years). The overall annual incidence rate for all ages was 3.9 (95% confidence interval [CI], 3.6-4.1) per 10,000 person-years and was significantly higher in male than in female patients (4.4 [95% CI, 4.0-4.7] and 3.3 [95% CI, 3.0-3.6], respectively; p < 0.001). The most common food allergen was egg in infancy (57.7%), peanuts in ages 1-4 years (58.3%), tree nuts in ages 5-18 years (57.4%), and seafood in adults (≥19 years) (45.3%). Conclusion: The incidence of food allergy in Olmsted County steadily increased from 2002 to 2008, then remained relatively stable between the years 2008 and 2013, and again presented a rising trend over the next 5 years until 2018. This warrants further investigations into the effects of changes in guidelines for early introductions of allergenic foods and other factors that affect causality.

Comparison of outcomes between pessary use and surgery for symptomatic pelvic organ prolapse: A prospective self-controlled study

Purpose

We compared the degree of pelvic floor symptom improvement between pessary use and prolapse surgery.

Materials and Methods

Pessary-naïve women who elected prolapse surgery were enrolled and used a pessary preoperatively (for ≥7 days and ≤30 days). Pelvic floor symptoms were assessed at baseline, after pessary use, and at 3 months postoperatively. The primary outcome was concordance in the degree of symptoms improvement between pessary use and surgery, as assessed by Patient Global Impression of Improvement (PGI-I). Secondary outcomes were related to prolapse specific symptoms on validated questionnaires (POPDI-6, PFIQ-7). The McNemar test was used for comparisons of discordant pairs for comparisons of the PGI-I ratings after pessary use and surgery.

Results

Sixty-one participants were enrolled (March 2016 through April 2019) and 58 patients used a pessary. Mean±standard deviation age was 60.7±10.7 years; 24.1% had prior hysterectomy, and 13.8% had prior prolapse surgery. While both treatments demonstrated symptomatic improvement, concordance in the degree of overall improvement on the PGI-I score was poor (n=40); responses significantly favored more improvement postoperatively (p<0.001). Pessary use and surgery were associated with significant improvements in prolapse symptoms from baseline on POPDI-6 (both p<0.001) and POPIQ-7 (pessary, p=0.002; surgery, p<0.001). The degree of improvement was larger postoperatively compared to post-pessary use on POPDI-6 (p<0.001) and PFIQ-7 (p=0.004).

Conclusions

Both pessary use and surgery significantly improved pelvic floor symptoms from baseline. However, concordance in degrees of improvement between these treatments was poor, with more favorable outcomes after surgery for prolapse symptoms.

Association of Perinatal Factors With Severe Obesity and Dyslipidemia in Adulthood

Background:

Perinatal factors including gestational age, birthweight, size for gestational age, delivery route, maternal parity, maternal age, maternal education, socioeconomic status, race, and sex, are associated with the future risk of obesity and co-morbid conditions. This study evaluated the relationship of birthweight for gestational age and perinatal factors with severe obesity and dyslipidemia in adulthood.

Methods:

We conducted a population-based, retrospective birth cohort study of infants born to residents of Olmsted County, MN between 1976 and 1982. Outcomes were assessed after age 18 years until October 2020, including severe obesity (BMI ≥ 40 kg/m²) and dyslipidemia (total cholesterol ≥200 mg/dL, non-high density lipoprotein [non-HDL] cholesterol ≥145 mg/dL or HDL cholesterol <40 mg/dL). We obtained mother’s age, education level, and parity as well as newborn sex, race, type of delivery, single/multiple birth, gestational age, and birthweight from birth certificate data. Individual-level socioeconomic status (SES) of the household at birth was determined with the HOUSES index.

Results:

Of 10 938 birth cohort subjects, 7394 had clinic visits after age 18 years and were included, with 2630 having severe obesity (n = 798) or dyslipidemia (n = 2357) as adults. In multivariable models, female sex, singleton birth, less maternal education, and lower SES defined by HOUSES were independently associated with an increased risk of severe obesity in adulthood. Non-white race, singleton birth, and lower birthweight were independently associated with adult dyslipidemia. Birthweight for gestational age was not associated with severe obesity or dyslipidemia.

Conclusion:

Perinatal factors were associated with both severe obesity and dyslipidemia in adulthood. Lower SES at birth was predictive of severe obesity in adulthood, highlighting the opportunity to investigate modifiable perinatal social determinants to reduce the risk of severe obesity.

Recalled Experiences of Bullying and Victimization in a Longitudinal, Population-Based Birth Cohort: The Influence of ADHD and Co-Occurring Psychiatric Disorder

OBJECTIVE

To describe bullying experiences throughout childhood of people with and without childhood ADHD and co-occurring learning and psychiatric disorders from a population-based birth cohort.

METHODS

In a secondary data analysis of 199 childhood ADHD cases and 287 non-ADHD referents (N = 486), reported experiences of peer interactions during elementary, middle, or high school were classified as "bully," "victim," "neither," or "both." Associations were assessed with multinomial logistic regression.

RESULTS

Adjusted for male sex, the odds of classification as victim-only, victim/bully, or bully- only (vs. neither) were 3.70 (2.36-5.81), 17.71, and 8.17 times higher for childhood ADHD cases compared to non-ADHD referents. Victim-bullies (62.5%) and bullies (64.3%) had both childhood ADHD and other psychiatric disorders versus 38.4% of victims-only and 17.3% of those classified as "neither."

CONCLUSION

The list of serious lifetime consequences of having ADHD also includes bullying. We offer future research directions for determining potential causal pathways.

Risk of substance use disorders among adolescents and emerging adults with type 1 diabetes: A population-based cohort study

BACKGROUND

Adolescents and emerging adults with chronic health conditions such as type 1 diabetes mellitus (T1D) are more likely to engage in high-risk behaviors. Previous studies regarding substance use in adolescents and emerging adults with T1D are mostly derived from cross-sectional studies utilizing self-administered questionnaires and are limited by lack of population-based comparison groups. In addition, despite the rising popularity of vaping, little is known about the incidence of vaping in adolescents and emerging adults with T1D.

METHODS

We explored the incidence and prospective risk of substance use disorders (SUD) and vaping in adolescents and emerging adults with T1D compared to age and gender matched nondiabetic referents residing in Olmsted County, Rochester, MN.

RESULTS

Risk of incident SUD was higher in those with T1D compared to matched referents with alcohol, marijuana, and smoked tobacco being most common substances. When stratified by gender, these differences remained significant in males, but not females.

CONCLUSIONS

While further work is needed to delineate the causative relationships between T1D, mental health, and substance abuse, our findings confirm the critical need for substance use screening and mental health support for adolescents and emerging adults with T1D.

IQ in Autism Spectrum Disorder: A Population-Based Birth Cohort Study

OBJECTIVES

We aimed to describe the intellectual ability and ratio of boys to girls with average or higher IQ within autism spectrum disorder (ASD) cases identified in a population-based birth cohort. We hypothesized that research-identified individuals with ASD would be more likely to have average or higher IQ, compared to clinically diagnosed ASD. We also hypothesized the male to female ratio would decrease as the definition of ASD broadened.

METHODS

ASD incident cases were identified from 31 220 subjects in a population-based birth cohort. Research-defined autism spectrum disorder, inclusive criteria (ASD-RI) was based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, autistic disorder (AD), Asperger Disorder, and pervasive developmental disorder not otherwise specified criteria. Research-defined autism spectrum disorder, narrow criteria (ASD-RN) was a narrower definition based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision AD criteria. Clinical diagnoses of ASD were abstracted from medical and school records. Intellectual ability was based on the last IQ score or on documented diagnoses of intellectual disability if no scores available. Average or higher IQ was defined as IQ ≥86.

RESULTS

A total of 59.1% of those with ASD-RI (n = 890), 51.2% of those with ASD-RN (n = 453), and 42.8% of those with clinically diagnosed autism spectrum disorder (n = 187) had average or higher IQ. Within the ASD-RI and ASD-RN groups, boys were more likely than girls to have an average or higher IQ (62.0% vs 51.3% [P = .004] and 54.1% vs. 42.5% [P = .03], respectively).

CONCLUSION

Our data suggest that nearly half of individuals with ASD have average or higher IQ. Boys with ASD are more likely to have average or higher IQ than girls. Patients with ASD and higher IQ remain at risk for not being identified.

Outcomes of Frozen Oocyte Donor In Vitro Fertilization (IVF) Cycles Using Fresh Versus Frozen Sperm

The ability to use frozen sperm for insemination during in vitro fertilization (IVF) is crucial for patients and for reproductive endocrinologists. However, concerns exist regarding the effects of cryopreservation on sperm quality and IVF outcomes. This study compares outcomes of frozen donor oocyte IVF cycles with intracytoplasmic sperm injection (ICSI) of good quality fresh versus frozen ejaculated sperm. Patients who underwent their first frozen donor oocyte IVF cycle between 2013 and 2019 at Mayo Clinic were identified. The primary outcome was live birth rate (LBR). Secondary outcomes included fertilization rate (FR), blastocyst development rate (BR), and clinical pregnancy rate (CPR). Twenty-six patients used fresh sperm and 19 patients utilized frozen sperm; there were no significant demographic differences between the groups. There were no significant differences noted in CPR, FR, and BR. Although the LBR was not statistically different when frozen versus fresh sperm was utilized (52.6% vs. 61.5%, p = 0.55), there was a distinct trend towards improved outcomes with fresh sperm that may be clinically significant. This data suggests that frozen sperm may be an alternative to a fresh sample, however fresh sperm may ultimately be a better option. This finding should be further explored with studies utilizing a larger sample size.

Evaluation of a Second Victim Peer Support Program on Perceptions of Second Victim Experiences and Supportive Resources in Pediatric Clinical Specialties Using the Second Victim Experience and Support Tool (SVEST)

PURPOSE

Pediatric healthcare professionals (HCPs) may experience events that lead to psychological distress or second victim experiences (SVEs). This project evaluates the impact of a newly implemented peer support program on SVEs and perceptions of supportive resources among pediatric HCPs.

DESIGN AND METHODS

A second victim (SV) peer support program was implemented in the pediatric inpatient and intensive care units in September 2019. Multidisciplinary HCPs in these units were invited to participate in an anonymous survey that included the Second Victim Experience and Support Tool before and one-year after implementation. The survey assessed HCPs' SVEs, desired support, and perceptions of the peer support program.

RESULTS

52.0% (194/373) completed the pre-implementation survey, and 43.9% (177/403) completed the post-implementation survey. At both timepoints, participants reported SV-related psychosocial distress, physical distress, or low professional self-efficacy; the most desired support was 'a respected peer to discuss the details of what happened'. Following implementation of the peer support program, HCPs were significantly more likely to have heard of the term 'second victim' (51.8 vs. 74.0%; p < 0.001) and to have felt like there were adequate resources to support SVs (35.8% vs. 89.1%; p < 0.001). In the post-implementation survey, most respondents indicated a likelihood to use the program for themselves (65.7%) or colleagues (84.6%) after involvement in future traumatic clinical events.

CONCLUSIONS

Implementation of a peer support program significantly influenced awareness and perceptions of support available for SV-related distress.

PRACTICE IMPLICATIONS

Peer support programs should be implemented to help HCPs navigate SVEs and decrease SV-related turnover intentions.

Ultrastaging of 'negative' pelvic lymph nodes in patients with low- and intermediate-risk endometrioid endometrial cancer who developed non-vaginal recurrences

OBJECTIVE

Evidence on micrometastases and isolated tumor cells as factors associated with non-vaginal recurrence in low- and intermediate-risk endometrial cancer is limited. The goal of our study was to investigate risk factors for non-vaginal recurrence in low- and intermediate-risk endometrial cancer.

METHODS

Records of all patients with endometrial cancer surgically managed at the Mayo Clinic before sentinel lymph node implementation (1999-2008) were reviewed. We identified all patients with endometrioid low-risk (International Federation of Gynecology and Obstetrics (FIGO) stage I, grade 1 or 2 with myometrial invasion <50% and negative peritoneal cytology) or intermediate-risk (FIGO stage I, grade 1 or 2 with myometrial invasion ≥50% or grade 3 with myometrial invasion <50% and negative peritoneal cytology) endometrial cancer at definitive pathology after pelvic and para-aortic lymph node assessment. All pelvic lymph nodes of patients with non-vaginal recurrence (any recurrence excluding isolated vaginal cuff recurrences) underwent ultrastaging.

RESULTS

Among 1303 women, we identified 321 patients with low-risk (n=236) or intermediate-risk (n=85) endometrial cancer (median age 65.4 years; 266 (82.9%) stage IA; 55 (17.1%) stage IB). Of the total of 321, 13 patients developed non-vaginal recurrence (Kaplan-Meier rate 4.7% by 60 months; 95% CI 2.1% to 7.2%): 11 hematogenous/peritoneal and two para-aortic and distant lymphatic. Myometrial invasion and lymphovascular space invasion were univariately associated with non-vaginal recurrence. In these patients, the original hematoxylin/eosin slides review confirmed all 646 pelvic and para-aortic removed lymph nodes as negative. The ultrastaging of 463 pelvic lymph nodes did not identify any occult metastases (prevalence 0%; 95% CI 0% to 22.8% considering 13 patients; 95% CI 0% to 0.8% considering 463 pelvic lymph nodes).

CONCLUSION

There were no occult metastases in pelvic lymph nodes of patients with low- or intermediate-risk endometrial cancer with non-vaginal recurrence. Myometrial invasion and lymphovascular space invasion appear to be associated with non-vaginal recurrence.

Association Between Exposure of Children to General Anesthesia and Autism Spectrum Disorder

This study tested the hypothesis that exposure of children prior to their third birthday to procedures requiring general anesthesia is associated with an increased incidence of autism spectrum disorder (ASD) in later life. This study employed a nested, 1:2 matched-case control study design using ASD cases identified in a population-based birth cohort of children born in Olmsted County, MN from 1976 to 2000. Matching variables included sex, date of birth, and mother's age in conditional logistic regression including 499 ASD cases and 998 controls. After adjusting for birth weight and health status, there was no significant association between exposure and ASD (OR 1.27 [95% CI 0.92-1.76]), indicating that general anesthesia is not associated with an increased risk of ASD.

Comparison of live birth rates after IVF-embryo transfer with and without preimplantation genetic testing for aneuploidies

RESEARCH QUESTION

Does the use of preimplantation genetic testing for aneuploidies (PGT-A) result in higher live birth rates when compared with both fresh and frozen embryo transfers (FET) not utilizing PGT-A?

DESIGN

Retrospective cohort study at a single tertiary centre using inverse probability of treatment weighting (IPTW) to adjust for differences in baseline characteristics between groups.

RESULTS

A total of 107 FET using PGT-A from 74 patients, along with 321 fresh and 286 FET not using PGT-A from 381 patients met the inclusion criteria for this study. In the IPTW-adjusted analysis of transfer-level data, PGT-A transfers resulted in a significantly higher live birth rate when compared with both non-PGT-A fresh (49.5% versus 38.6%, P = 0.036) and FET (50.6% versus 35.8%, P = 0.016). When data were analysed per retrieval level, the live birth rate was similar and acceptably high with or without PGT-A (63.7% versus 52.3%, P = 0.09).

CONCLUSION

When comparing PGT-A to non-PGT-A fresh and FET, PGT-A embryo transfers have a significantly higher live birth rate. However, this difference did not persist at a per-retrieval level. Further investigation is needed to understand in what scenarios PGT-A has clinical significance and whether differences in the number of available embryos for transfer negates the benefit of PGT-A.

Tao brush endometrial cytology is a sensitive diagnostic tool for cancer and hyperplasia among women presenting to clinic with abnormal uterine bleeding

Background

Abnormal uterine bleeding requires the investigation of the endometrium. Histology is typically used but there remains room for the improvement and use of cytology.

Methods

Women presenting for clinically indicated office endometrial biopsy were prospectively enrolled. Tao endometrial brushing and office endometrial biopsy were performed, and surgical procedure if clinically indicated. Tao brush cytology specimens were blindly reviewed by up to three pathologists, consensus obtained, and scored as: benign, atypical (favor benign), suspicious, positive for malignancy, or non‐diagnostic. Cytology and histology were compared to surgical pathology to determine sensitivity, specificity, positive, and negative predictive values to detect AH (atypical hyperplasia) or EC (endometrial cancer).

Results

Clinical indications of 197 enrolled patients included postmenopausal bleeding (90, 45.7%), abnormal uterine bleeding (94, 47.7%), and abnormal endometrium on ultrasound without bleeding (13, 6.6%). Of the 197 patients, 185 (93.9%) had cytology score consensus and a total of 196 (99.5%) had consensus regarding cytology positivity.

Surgical pathology diagnoses (N = 85) were 13 (15.3%) FIGO grade 1 or 2 EC, 3 (3.5%) AH, and 69 (81.2%) benign endometrium. Sensitivity and specificity to detect EC or AH were 93.7% and 100%, respectively, via endometrial biopsy; 87.5% and 63.8%, respectively, via endometrial cytology when scores of malignancy, suspicious, or atypical were considered positive.

Conclusions

In a high‐risk population, Tao brush endometrial cytology showed high sensitivity to detect AH and EC comparable to biopsy histology when considering scores of malignancy, suspicious, atypical, and non‐diagnostic. Revisiting the potential value of endometrial cytology in the contemporary era of endometrial diagnostic workup is warranted.

Pregnancy and birth outcomes after SARS-CoV-2 vaccination in pregnancy

BACKGROUND

SARS-CoV-2 infection during pregnancy is associated with significant maternal morbidity and increased rates of preterm birth. For this reason, COVID-19 vaccination in pregnancy has been endorsed by multiple professional societies, including the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine, despite the exclusion of pregnant women from initial clinical trials of vaccine safety and efficacy. However, to date, little data exist regarding the outcomes of pregnant patients after COVID-19 vaccination.

OBJECTIVE

To assess the safety and efficacy of COVID-19 vaccines in pregnant patients.

STUDY DESIGN

A comprehensive vaccine registry was combined with a delivery database for an integrated healthcare system to create a delivery cohort that included vaccinated patients. Maternal sociodemographic data were examined to identify factors associated with COVID-19 vaccination. Pregnancy and birth outcomes were analyzed, including a composite measure of maternal and neonatal pregnancy complications, the Adverse Outcome Index.

RESULTS

Of 2002 patients in the delivery cohort, 140 (7.0%) received a COVID-19 vaccine during pregnancy, and 212 (10.6%) experienced a COVID-19 infection during pregnancy. The median gestational age at first vaccination was 32 weeks (range, 13 6/7–40 4/7 weeks), and patients vaccinated during pregnancy were less likely than unvaccinated patients to experience COVID-19 infection before delivery (2/140 [1.4%] vs 210/1862 [11.3%]; P<.001). No maternal COVID-19 infection occurred after the vaccination of pregnant patients. Factors significantly associated with increased likelihood of vaccination in a multivariable logistic regression model included older age, higher level of maternal education, being a nonsmoker, use of infertility treatment for the current pregnancy, and lower gravidity. Compared with unvaccinated patients, no significant difference in the composite adverse outcome (7/140 [5.0%] vs 91/1862 [4.9%]; P=.95) or other maternal or neonatal complications, including thromboembolic events and preterm birth, was observed in vaccinated patients.

CONCLUSION

In this birth cohort, vaccinated pregnant women were less likely than unvaccinated pregnant patients to experience COVID-19 infection, and COVID-19 vaccination during pregnancy was not associated with increased pregnancy or delivery complications. The cohort was skewed toward late pregnancy vaccination, and thus, findings may not be generalizable to vaccination during early pregnancy.

Evaluating Markers of Immune Tolerance and Angiogenesis in Maternal Blood for an Association with Risk of Pregnancy Loss

Pregnancy loss affects approximately 20% of couples. The lack of a clear cause complicates half of all miscarriages. Early evidence indicates the maternal immune system and angiogenesis regulation are both key players in implantation success or failure. Therefore, this prospective study recruited women in the first trimester with known viable intrauterine pregnancy and measured blood levels of immune tolerance proteins galectin-9 (Gal-9) and interleukin (IL)-4, and angiogenesis proteins (vascular endothelial growth factors (VEGF) A, C, and D) between 5 and 9 weeks gestation. Plasma concentrations were compared between groups defined based on (a) pregnancy outcome and (b) maternal history of miscarriage, respectively. In total, 56 women were recruited with 10 experiencing a miscarriage or pregnancy loss in the 2nd or 3rd trimester and 11 having a maternal history or miscarriage. VEGF-C was significantly lower among women with a miscarriage or pregnancy loss. Gal-9 and VEGF-A concentrations were decreased in women with a prior miscarriage. Identification of early changes in maternal immune and angiogenic factors during pregnancy may be a tool to improve patient counseling on pregnancy loss risk and future interventions to reduce miscarriage in a subset of women.

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.
