RESUMO
Differential diagnosis is sometimes difficult in practical psychiatric settings, in terms of using the current diagnostic system based on presenting symptoms and signs. The creation of a novel diagnostic system using objective biomarkers is expected to take place. Neuroimaging studies and others reported that subcortical brain structures are the hubs for various psycho-behavioral functions, while there are so far no neuroimaging data-driven clinical criteria overcoming limitations of the current diagnostic system, which would reflect cognitive/social functioning. Prior to the main analysis, we conducted a large-scale multisite study of subcortical volumetric and lateralization alterations in schizophrenia, bipolar disorder, major depressive disorder, and autism spectrum disorder using T1-weighted images of 5604 subjects (3078 controls and 2526 patients). We demonstrated larger lateral ventricles volume in schizophrenia, bipolar disorder, and major depressive disorder, smaller hippocampus volume in schizophrenia and bipolar disorder, and schizophrenia-specific smaller amygdala, thalamus, and accumbens volumes and larger caudate, putamen, and pallidum volumes. In addition, we observed a leftward alteration of lateralization for pallidum volume specifically in schizophrenia. Moreover, as our main objective, we clustered the 5,604 subjects based on subcortical volumes, and explored whether data-driven clustering results can explain cognitive/social functioning in the subcohorts. We showed a four-biotype classification, namely extremely (Brain Biotype [BB] 1) and moderately smaller limbic regions (BB2), larger basal ganglia (BB3), and normal volumes (BB4), being associated with cognitive/social functioning. Specifically, BB1 and BB2-3 were associated with severe and mild cognitive/social impairment, respectively, while BB4 was characterized by normal cognitive/social functioning. Our results may lead to the future creation of novel biological data-driven psychiatric diagnostic criteria, which may be expected to be useful for prediction or therapeutic selection.
RESUMO
According to the operational diagnostic criteria, psychiatric disorders such as schizophrenia (SZ), bipolar disorder (BD), major depressive disorder (MDD), and autism spectrum disorder (ASD) are classified based on symptoms. While its cluster of symptoms defines each of these psychiatric disorders, there is also an overlap in symptoms between the disorders. We hypothesized that there are also similarities and differences in cortical structural neuroimaging features among these psychiatric disorders. T1-weighted magnetic resonance imaging scans were performed for 5,549 subjects recruited from 14 sites. Effect sizes were determined using a linear regression model within each protocol, and these effect sizes were meta-analyzed. The similarity of the differences in cortical thickness and surface area of each disorder group was calculated using cosine similarity, which was calculated from the effect sizes of each cortical regions. The thinnest cortex was found in SZ, followed by BD and MDD. The cosine similarity values between disorders were 0.943 for SZ and BD, 0.959 for SZ and MDD, and 0.943 for BD and MDD, which indicated that a common pattern of cortical thickness alterations was found among SZ, BD, and MDD. Additionally, a generally smaller cortical surface area was found in SZ and MDD than in BD, and the effect was larger in SZ. The cosine similarity values between disorders were 0.945 for SZ and MDD, 0.867 for SZ and ASD, and 0.811 for MDD and ASD, which indicated a common pattern of cortical surface area alterations among SZ, MDD, and ASD. Patterns of alterations in cortical thickness and surface area were revealed in the four major psychiatric disorders. To our knowledge, this is the first report of a cross-disorder analysis conducted on four major psychiatric disorders. Cross-disorder brain imaging research can help to advance our understanding of the pathogenesis of psychiatric disorders and common symptoms.

OBJECTIVES: A lack of diversity amongst participants in cancer clinical trials has raised scrutiny over the past decade. Patients with limited English proficiency (LEP) are further excluded. One modifiable reason for low LEP participation is a lack of non-English consent forms. METHODS: We queried the clinical trials registry database at an academic hospital serving a predominantly Spanish-speaking patient population. Clinical trials related to gynecology oncology were evaluated for the availability of fully translated Spanish consent forms, the racial and ethnic identification of enrolled patients, and the number of signed Spanish consents. Enrolment data was compared before and after 2019, when institutional financial support for document translation was withdrawn. RESULTS: Sixteen gynecologic oncology clinical trials were opened between 2014 and 2022, with 10 trials enrolling 128 patients. Eight trials opened prior to 2019, all with fully translated consent forms. Seven of these trials enrolled 99 participants, 70% of whom identified as Hispanic and 60% who signed a Spanish consent. Eight trials opened after 2019 and one had a fully translated consent form. Three of the trials enrolled 29 participants, with 10% of subjects identifying as Hispanic and none signing a Spanish consent form. CONCLUSIONS: There was a decrease in fully translated clinical trial consent forms for gynecologic oncology studies following the loss of subsidized translation services in our single institution with a predominantly LEP population. This correlated with a decrease in enrollment of Hispanic subjects. To increase enrollment of diverse participants, including those with LEP, simple actions such as fully translating consent forms would help maintain equity in research conduct and improve clinical outcomes through trial involvement.

OBJECTIVE: To assess (i) clinical and pregnancy characteristics, (ii) patterns of surgical procedures, and (iii) surgical morbidity associated with cesarean hysterectomy for placenta accreta spectrum based on the specialty of the attending surgeon. METHODS: The Premier Healthcare Database was queried retrospectively to study patients with placenta accreta spectrum who underwent cesarean delivery and concurrent hysterectomy from 2016 to 2020. Surgical morbidity was assessed with propensity score inverse probability of treatment weighting based on surgeon specialty for hysterectomy: general obstetrician-gynecologists, maternal-fetal medicine specialists, and gynecologic oncologists. RESULTS: A total of 2240 cesarean hysterectomies were studies. The most common surgeon type was general obstetrician-gynecologist (n = 1534, 68.5%), followed by gynecologic oncologist (n = 532, 23.8%) and maternal-fetal medicine specialist (n = 174, 7.8%). Patients in the gynecologic oncologist group had the highest rate of placenta increta or percreta, followed by the maternal-fetal medicine specialist and general obstetrician-gynecologist groups (43.4%, 39.6%, and 30.6%, P < .001). In a propensity score-weighted model, measured surgical morbidity was similar across the three subspecialty groups, including hemorrhage / blood transfusion (59.4-63.7%), bladder injury (18.3-24.0%), ureteral injury (2.2-4.3%), shock (8.6-10.5%), and coagulopathy (3.3-7.4%) (all, P > .05). Among the cesarean hysterectomy performed by gynecologic oncologist, hemorrhage / transfusion rates remained substantial despite additional surgical procedures: tranexamic acid / ureteral stent (60.4%), tranexamic acid / endo-arterial procedure (76.2%), ureteral stent / endo-arterial procedure (51.6%), and all three procedures (55.4%). Tranexamic acid administration with ureteral stent placement was associated with decreased bladder injury (12.8% vs 23.8-32.2%, P < .001). CONCLUSION: These data suggest that patient characteristics and surgical procedures related to cesarean hysterectomy for placenta accreta spectrum differ based on surgeon specialty. Gynecologic oncologists appear to manage more severe forms of placenta accreta spectrum. Regardless of surgeon's specialty, surgical morbidity of cesarean hysterectomy for placenta accreta spectrum is significant.

OBJECTIVE: To assess the prognostic performance of the 2023 International Federation of Gynecology and Obstetrics (FIGO) endometrial cancer staging schema. METHODS: This retrospective cohort study queried the Commission-on-Cancer's National Cancer Database. Study population was 129,146 patients with stage I-IV endometrial cancer per the 2009 FIGO staging schema. Stage-shifting and overall survival (OS) were assessed according to the 2023 FIGO staging schema. RESULTS: Upstage (IAâ¯ââ¯II, 21.4â¯%; IBâ¯ââ¯II, 53.0â¯%) and downstage (IIIAâIA3, 22.2â¯%) occurred in both early and advanced diseases. Inter-stage prognostic performance improved in the 2023 schema with widened 5-year OS rate difference between the earliest and highest stages (68.2â¯% to 76.9â¯%). Stage IA1-IIB and IIC had distinct 5-year OS rate differences (85.8-96.1â¯% vs 75.4â¯%). The 5-year OS rate of the 2009 stage IIIA disease was 63.9â¯%; this was greater segregated in the 2023 schema: 88.0â¯%, 62.4â¯%, and 55.7â¯% for IIIAâIA3, IIIA1, and IIIA2, respectively (inter-substage rate-difference, 32.3â¯%). This 5-year OS rate of stage IA3 disease was comparable to the 2023 stage IB-IIB diseases (88.0â¯% vs 85.8-89.5â¯%). In the 2023 stage IIIC schema (micrometastasis rates: 29.6â¯% in IIIC1 and 15.6â¯% in IIIC2), micrometastasis and macrometastasis had the distinct 3-year OS rates in both pelvic (IIIC1-i vs IIIC1-ii, 84.9â¯% vs 71.1â¯%; rate-difference 13.8â¯%) and para-aortic (IIIC2-i vs IIIC2-ii, 82.9â¯% vs 65.2â¯%; rate-difference 17.7â¯%) nodal metastasis cases. The 5-year OS rate of the 2009 stage IVB disease was 23.4â¯%; this was segregated to 25.4â¯% for stage IVB and 19.2â¯% for stage IVC in the 2023 staging schema (rate-difference, 6.2â¯%). CONCLUSION: The 2023 FIGO endometrial cancer staging schema is a major revision from the 2009 FIGO schema. Almost doubled enriched sub-stages based on detailed anatomical metastatic site and incorporation of histological information enable more robust prognostication.

OBJECTIVE: Combination cediranib/olaparib has reported activity in relapsed ovarian cancer. This phase 2 trial investigated the activity of cediranib/olaparib in relapsed ovarian cancer and its association with homologous recombination deficiency (HRD). METHODS: Seventy patients were enrolled to cohorts of either platinum-sensitive or platinum-resistant ovarian cancer and received olaparib tablets 200 mg twice daily and cediranib tablets 30 mg once daily under a continuous dosing schedule. HRD testing was performed on pre-treatment, on-treatment and archival biopsies by sequencing key homologous recombination repair (HRR) genes and by genomic LOH analysis. The primary objective for the platinum-sensitive cohort was the association of HRD, defined as presence of HRR gene mutation, with progression-free survival (PFS). The primary objective for the platinum-resistant cohort was objective response rate (ORR), with a key secondary endpoint evaluating the association of HRD status with activity. RESULTS: In platinum-sensitive ovarian cancer (N = 35), ORR was 77.1% (95% CI 59.9-89.6%) and median PFS was 16.4 months (95% CI 13.2-18.6). Median PFS in platinum-sensitive HRR-HRD cancers (N = 22) was 16.8 months (95% CI 11.3-18.6), and 16.4 months (95% CI 9.4-NA) in HRR-HR proficient cancers (N = 13; p = 0.57). In platinum-resistant ovarian cancer (N = 35), ORR was 22.9% (95% CI 10.4-40.1%) with median PFS 6.8 months (95% CI 4.2-9.1). Median PFS in platinum-resistant HRR-HRD cancers (N = 7) was 10.5 months (95% CI 3.6-NA) and 5.6 months (95% CI 3.6-7.6) in HRR-HR proficient cancers (N = 18; p = 0.23). CONCLUSIONS: Cediranib/olaparib had clinical activity in both platinum-sensitive and -resistant ovarian cancer. Presence of HRR gene mutations was not associated with cediranib/olaparib activity in either setting.

OBJECTIVE: The increasing use of fertility-preserving treatments in reproductive-aged patients with early-stage endometrial cancer necessitates robust evidence on the effectiveness of oral progestins and levonorgestrel-releasing intrauterine device (LNG-IUD). We conducted a systematic review and meta-analysis to examine outcomes following these two primary progestin-based therapies in reproductive-aged patients with early-stage endometrial cancer. DATA SOURCES: We conducted a systematic review of observational studies and randomized controlled trials following the Cochrane Handbook guidance. We conducted a literature search of five databases and one trial registry from inception of the study to April 16, 2024. STUDY ELIGIBILITY CRITERIA: Studies reporting complete response within one year in reproductive-aged patients with clinical stage IA endometrioid cancer undergoing progestin therapy treatment were included. We used data from both observational and randomized controlled studies. STUDY APPRAISAL AND SYNTHESIS METHODS: The primary exposure assessed was the type of progestational treatment (oral progestins or LNG-IUD). The primary outcome was the pooled proportion of the best complete response (CR) within one year of primary progestational treatment. We performed a proportional meta-analysis to estimate the treatment response. Sensitivity analyses were performed by removing studies with extreme effect sizes or removing grade 2 tumors. The risk of bias was assessed in each study using the Joanna Briggs Institute critical appraisal checklist RESULTS: Our analysis involved 754 reproductive-aged patients diagnosed with endometrial cancer, with 490 receiving oral progestin and 264 receiving LNG-IUD as their primary progestational treatment. The pooled proportion of the best CR within 12 months of oral progestin and LNG-IUD treatment were 66% (95% CI, 55-76) and 86% (95% CI, 69-95), respectively. After removing outlier studies, the pooled proportion was 66% (95% CI, 57-73) for the oral progestin group, and 89% (95% CI, 75-96) for the LNG-IUD group, showing reduced heterogeneity. Specifically, among studies including grade 1 tumors, the pooled proportions were 66% (95% CI, 54-77) for the oral progestin group and 83% (95% CI, 50-96) for the LNG-IUD group. The pooled pregnancy rate was 58% (95% CI, 37-76) after oral progestin treatment and 44% (95% CI, 6-90) after LNG-IUD treatment. CONCLUSIONS: This meta-analysis provides valuable insights into the effectiveness of oral progestins and LNG-IUD treatment within a 12-month timeframe for patients with early-stage endometrial cancer who desire to preserve fertility. These findings have the potential to assist in personalized treatment decision-making for patients.
RESUMO
BACKGROUND: Racial and ethnic differences in early death after cancer diagnosis have not been well studied in gynecologic malignancy. OBJECTIVE: This study aimed to assess population-level trends and characteristics of early death among patients with gynecologic malignancy based on race and ethnicity in the United States. STUDY DESIGN: The National Cancer Institute's Surveillance, Epidemiology, and End Results Program was queried to examine 461,300 patients with gynecologic malignancies from 2000 to 2020, including uterine (n=242,709), tubo-ovarian (n=119,989), cervical (n=68,768), vulvar (n=22,991), and vaginal (n=6843) cancers. Early death, defined as a mortality event within 2 months of the index cancer diagnosis, was evaluated per race and ethnicity. RESULTS: At the cohort level, early death occurred in 21,569 patients (4.7%), including 10.5%, 5.5%, 2.9%, 2.5%, and 2.4% for tubo-ovarian, vaginal, cervical, uterine, and vulvar cancers, respectively (P<.001). In a race- and ethnicity-specific analysis, non-Hispanic Black patients with tubo-ovarian cancer had the highest early death rate (14.5%). Early death racial and ethnic differences were the largest in tubo-ovarian cancer (6.4% for Asian vs 14.5% for non-Hispanic Black), followed by uterine (1.6% for Asian vs 4.9% for non-Hispanic Black) and cervical (1.8% for Hispanic vs 3.8% to non-Hispanic Black) cancers (all, P<.001). In tubo-ovarian cancer, the early death rate decreased over time by 33% in non-Hispanic Black patients from 17.4% to 11.8% (adjusted odds ratio, 0.67; 95% confidence interval, 0.53-0.85) and 23% in non-Hispanic White patients from 12.3% to 9.5% (adjusted odds ratio, 0.77; 95% confidence interval, 0.71-0.85), respectively. The early death between-group difference diminished only modestly (12.3% vs 17.4% for 2000-2002 [adjusted odds ratio for non-Hispanic White vs non-Hispanic Black, 0.54; 95% confidence interval, 0.45-0.65] and 9.5% vs 11.8% for 2018-2020 [adjusted odds ratio, 0.65; 95% confidence interval, 0.54-0.78]). CONCLUSION: Overall, approximately 5% of patients with gynecologic malignancy died within the first 2 months from cancer diagnosis, and the early death rate exceeded 10% in non-Hispanic Black individuals with tubo-ovarian cancer. Although improving early death rates is encouraging, the difference among racial and ethnic groups remains significant, calling for further evaluation.

INTRODUCTION: This study aimed to assess the effectiveness of calcimimetics in reducing the risk of fractures in dialysis patients with secondary hyperparathyroidism (SHPT). MATERIAL AND METHODS: A comprehensive literature search was conducted using PubMed, Embase, and Cochrane Library for articles published through December 9, 2023. The quality of each trial was evaluated using the Cochrane Collaboration tool. Meta-analysis was performed using a random-effects model, and effect measures across studies were synthesized. The risk ratio (RR) and 95% confidence interval (CI) were used to quantify the risk of fracture. RESULTS: We identified seven studies involving 6481 dialysis patients with SHPT. The administration of calcimimetics reduced fracture incidence compared to placebo or conventional treatment (RR: 0.50, 95% CI 0.29-0.88, p = 0.02). Calcimimetics demonstrated a low number needed to treat (NNT) to prevent an incident fracture (NNT: 47). CONCLUSION: The use of calcimimetics offers a significant benefit in reducing the risk of fractures in patients undergoing dialysis with SHPT.

BACKGROUND: Low muscle mass in patients with acute heart failure (AHF) is associated with poor prognosis; however, this is based on a single baseline measurement, with little information on changes in muscle mass during hospitalization and their clinical implications. This study investigated the relationship between changes in rectus femoris cross-sectional area (RFCSA) on ultrasound and the prognosis of patients with AHF. METHODSâANDâRESULTS: This is a retrospective evaluation of 284 AHF patients (mean [±SD] age 79.1±11.9 years; 116 female). RFCSA assessments at admission (pre-RFCSA), ∆RFCSA (i.e., the percentage change in RFCSA from admission to 2 weeks), and composite prognosis (all-cause death and heart failure-related readmission) within 1 year were determined. Patients were divided into 4 groups according to their median pre-RFCSA and ∆RFCSA after sex stratification: Group A, higher pre-RFCSA/better ∆RFCSA; Group B, higher pre-RFCSA/worse ∆RFCSA; Group C, lower pre-RFCSA/better ∆RFCSA; Group D, lower pre-RFCSA/worse ∆RFCSA. In the Cox regression analysis, with Group A as the reference, the cumulative event rate of Group C (hazard ratio [HR] 3.39; 95% confidence interval [CI] 0.71-16.09; P=0.124) did not differ significantly; however, the cumulative event rates of Group B (HR 7.93; 95% CI 1.99-31.60; P=0.003) and Group D (HR 9.24; 95% CI 2.57-33.26; P<0.001) were significantly higher. CONCLUSIONS: ∆RFCSA during hospitalization is useful for risk assessment of prognosis in patients with AHF.

Observational and cohort studies using large databases have made important contributions to gynecologic oncology. Knowledge of the advantages and potential limitations of commonly used databases benefits both readers and reviewers. In this review, researchers familiar with National Cancer Database (NCDB), Surveillance, Epidemiology, and End Results Program (SEER), SEER-Medicare, MarketScan, Healthcare Cost and Utilization Project (HCUP), National Surgical Quality Improvement Program (NSQIP), and Premier, describe each database, its included data, access, management, storage, highlights, and limitations. A better understanding of these commonly used datasets can help readers, reviewers, and researchers to more effectively interpret and apply study results, evaluate new research studies, and develop compelling and practice-changing research.
RESUMO
OBJECTIVE: The objective of this study was to assess the oncologic outcome of surgically-treated patients with early-stage, intermediate-risk cervical cancer according to postoperative therapy modality. METHODS: This retrospective cohort study queried the Japanese Gynecologic Oncology Group's nationwide surgical data platform. The study population was 1084 patients with stage IB cervical cancer who underwent primary radical hysterectomy and lymphadenectomy from 2004 to 2008. Histology type-incorporated intermediate-risk factor patterns were clustered into three groups based on recurrence risk. Oncologic outcomes were assessed per postoperative therapy: external beam radiotherapy alone, concurrent chemo-radiotherapy, chemotherapy alone, and no treatment. RESULTS: Histology-incorporated intermediate-risk groups included: no lympho-vascular space invasion in any histology, or squamous cell carcinoma with lympho-vascular space invasion but no deep stromal invasion (n=559, 51.6%, group 1); squamous cell carcinoma with both lympho-vascular space invasion and deep cervical stromal invasion (n=281, 25.9%; group 2); and non-squamous histology with lympho-vascular space invasion (n=244, 22.5%; group 3). The 5-year disease-free survival rates were 93.3%, 89.3%, and 82.5% for group 1,-2, and -3, respectively (p<0.001), with group 3 exhibiting an almost three-fold increased recurrence risk compared with group 1 (adjusted-hazard ratio (aHR) 2.70, 95% confidence interval (CI) 1.70-4.32), followed by group 2 (aHR 1.67, 95% CI 1.01 to 2.75). Disease-free survival was similar across the postoperative therapy groups: 5 year rates for external beam radiotherapy alone, concurrent chemo-radiotherapy, chemotherapy alone, and no postoperative treatment, 94.8%, 87.2%, 93.6%, and 94.2% for group 1 (p=0.294); 85.0%, 93.3%, 87.3%, and 90.5% for group 2 (p=0.578); and 85.4%, 83.1%, 80.5%, and 83.3% for group 3 (p=0.876). The aHR for disease-free survival comparing no postoperative treatment to external beam radiotherapy alone was 1.10 (95% CI 0.37 to 3.28), 0.71 (95% CI 0.29 to 1.79), and 1.21 (95% CI 0.42 to 3.51) for group 1, group 2, and group 3, respectively. The observed exposure-outcome associations were similar for cause-specific survival (all, p>0.05). CONCLUSION: In this retrospective investigation in Japan, active surveillance without postoperative therapy following radical hysterectomy and lymphadenectomy was not associated with oncologic outcome in early-stage, intermediate-risk cervical cancer.
RESUMO
OBJECTIVE: To examine the association between intrauterine manipulator use and pathological factors and oncologic outcomes in patients with endometrial cancer who had laparoscopic hysterectomy in Japan. METHODS: This was a nationwide retrospective cohort study of the tumor registry of the Japan Society of Obstetrics and Gynecology. Study population was 3846 patients who had laparoscopic hysterectomy for endometrial cancer from January 2015 to December 2017. An automated 1-to-1 propensity score matching with preoperative and intraoperative demographics was performed to assess postoperative pathological factors associated with the intrauterine manipulator. Survival outcomes were assessed by accounting for possible pathological mediators related to intrauterine manipulator use. RESULTS: Most patients had preoperative stage I disease (96.5%) and grade 1-2 endometrioid tumors (81.9%). During the study period, 1607 (41.8%) patients had intrauterine manipulator use and 2239 (58.2%) patients did not. In the matched cohort, the incidences of lymphovascular space invasion in the hysterectomy specimen were 17.8% in the intrauterine manipulator group and 13.3% in the non-manipulator group. Intrauterine manipulator use was associated with a 35% increased odds of lymphovascular space invasion (adjusted odds ratio 1.35, 95% confidence interval (CI) 1.08 to 1.69). The incidences of malignant cells identified in the pelvic peritoneal cytologic sample at hysterectomy were 10.8% for the intrauterine manipulator group and 6.4% for the non-manipulator group. Intrauterine manipulator use was associated with a 77% increased odds of malignant peritoneal cytology (adjusted odds ratio 1.77, 95% Cl 1.29 to 2.31). The 5 year overall survival rates were 94.2% for the intrauterine manipulator group and 96.6% for the non-manipulator group (hazard ratio (HR) 1.64, 95% Cl 1.12 to 2.39). Possible pathological mediators accounted HR was 1.36 (95%Cl 0.93 to 2.00). CONCLUSION: This nationwide analysis of predominantly early stage, low-grade endometrial cancer in Japan suggested that intrauterine manipulator use during laparoscopic hysterectomy for endometrial cancer may be associated with an increased risk of lymphovascular space invasion and malignant peritoneal cytology. Possible mediator effects of intrauterine manipulator use on survival warrant further investigation, especially with a prospective setting.

INTRODUCTION: Since malignancy during pregnancy is uncommon, information regarding contraception selection or sterilization at delivery is limited. The objective of this study was to examine the type of long-acting reversible contraception or surgical sterilization procedure chosen by pregnant patients with malignancy at delivery. MATERIAL AND METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample in the USA. The study population was vaginal and cesarean deliveries in a hospital setting from January 2017 to December 2020. Pregnant patients with breast cancer (n = 1605), leukemia (n = 1190), lymphoma (n = 1120), thyroid cancer (n = 715), cervical cancer (n = 425) and melanoma (n = 400) were compared with 14 265 319 pregnant patients without malignancy. The main outcome measures were utilization of long-acting reversible contraception (subdermal implant or intrauterine device) and performance of permanent surgical sterilization (bilateral tubal ligation or bilateral salpingectomy) during the index hospital admission for delivery, assessed with a multinomial regression model controlling for clinical, pregnancy and delivery characteristics. RESULTS: When compared with pregnant patients without malignancy, pregnant patients with breast cancer were more likely to proceed with bilateral salpingectomy (adjusted odds ratio [aOR] 2.30) or intrauterine device (aOR 1.91); none received the subdermal implant. Pregnant patients with leukemia were more likely to choose a subdermal implant (aOR 2.22), whereas those with lymphoma were more likely to proceed with bilateral salpingectomy (aOR 1.93) and bilateral tubal ligation (aOR 1.76). Pregnant patients with thyroid cancer were more likely to proceed with bilateral tubal ligation (aOR 2.21) and none received the subdermal implant. No patients in the cervical cancer group selected long-acting reversible contraception, and they were more likely to proceed with bilateral salpingectomy (aOR 2.08). None in the melanoma group chose long-acting reversible contraception. Among pregnant patients aged <30, the odds of proceeding with bilateral salpingectomy were increased in patients with breast cancer (aOR 3.01), cervical cancer (aOR 2.26) or lymphoma (aOR 2.08). The odds of proceeding with bilateral tubal ligation in pregnant patients aged <30 with melanoma (aOR 5.36) was also increased. CONCLUSIONS: The results of this nationwide assessment in the United States suggest that among pregnant patients with malignancy, the preferred contraceptive option or method of sterilization at time of hospital delivery differs by malignancy type.

PURPOSE: To examine feto-maternal characteristics and outcomes of morbidly obese pregnant patients who conceived with assisted reproductive technology (ART). METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's National Inpatient Sample. Study population was 48,365 patients with ART pregnancy from January 2012 to September 2015, including non-obesity (n = 45,125, 93.3%), class I-II obesity (n = 2445, 5.1%), and class III obesity (n = 795, 1.6%). Severe maternal morbidity at delivery per the Centers for Disease and Control Prevention definition was assessed with multivariable binary logistic regression model. RESULTS: Patients in the class III obesity group were more likely to have a hypertensive disorder (adjusted-odds ratio (aOR) 3.03, 95% confidence interval (CI) 2.61-3.52), diabetes mellitus (aOR 3.08, 95%CI 2.64-3.60), large for gestational age neonate (aOR 3.57, 95%CI 2.77-4.60), and intrauterine fetal demise (aOR 2.03, 95%CI 1.05-3.94) compared to those in the non-obesity group. Increased risks of hypertensive disease (aOR 1.35, 95%CI 1.14-1.60) and diabetes mellitus (aOR 1.39, 95%CI 1.17-1.66) in the class III obesity group remained robust even compared to the class I-II obesity group. After controlling for priori selected clinical, pregnancy, and delivery factors, patients with class III obesity were 70% more likely to have severe maternal morbidity at delivery compared to non-obese patients (8.2% vs 4.4%, aOR 1.70, 95%CI 1.30-2.22) whereas those with class I-II obesity were not (4.1% vs 4.4%, aOR 0.87, 95%CI 0.70-1.08). CONCLUSIONS: The results of this national-level analysis in the United States suggested that morbidly obese pregnant patients conceived with ART have increased risks of adverse fetal and maternal outcomes.

PURPOSE: To examine the utilization and characteristics related to the use of hysteroscopy at the time of endometrial evaluation for endometrial hyperplasia in the outpatient surgery setting. METHODS: This cross-sectional study queried the Healthcare Cost and Utilization Project's Nationwide Ambulatory Surgery Sample. The study population was 3218 patients with endometrial hyperplasia who underwent endometrial evaluation from January 2016 to December 2019. Performance and clinical characteristics of hysteroscopic endometrial evaluation were assessed with multivariable binary logistic regression models. RESULTS: A total of 2654 (82.5%) patients had hysteroscopic endometrial tissue evaluation. Patients with postmenopausal bleeding, heavy menstrual bleeding, and polycystic ovary syndrome were more likely to undergo hysteroscopic endometrial evaluation in multivariable analysis (all, adjusted-P < 0.001). Uterine injury occurred in 4.9 per 1000 hysteroscopic endometrial evaluations; none had uterine injury in the non-hysteroscopy cohort. Among the 2654 patients who had hysteroscopic endometrial evaluation, 106 (4.0%) patients had intrauterine device insertion at surgery, and the utilization increased from 2.9 to 5.8% during the study period (P-trend < 0.001). Younger age, more recent year surgery, and obesity were independently associated with increased utilization of intrauterine device insertion at hysteroscopic endometrial evaluation (all, adjusted-P < 0.05). Among 2023 reproductive-age patients with endometrial hyperplasia, 1666 (82.4%) patients underwent hysteroscopic endometrial evaluation. On multivariable analysis, patients with heavy menstrual bleeding were more likely to have hysteroscopic endometrial evaluation (adjusted-P < 0.05). Intrauterine device insertion increased from 3.7% in 2016 to 8.0% in 2019 (P-trend = 0.007). CONCLUSION: This nationwide analysis suggests that the insertion of intrauterine devices at the time of hysteroscopic endometrial tissue evaluation for endometrial hyperplasia is increasing among reproductive-age population.

OBJECTIVE: This study analyzes national trends in the management of uncomplicated appendicitis during pregnancy, comparing outcomes for nonoperative management (NOM) and appendectomy. BACKGROUND: In the nonpregnant population, several randomized controlled trials demonstrated noninferiority of NOM compared with appendectomy for acute uncomplicated appendicitis. However, it remains unclear whether these findings are generalizable to pregnant patients. METHODS: The National Inpatient Sample was queried for pregnant women diagnosed with acute uncomplicated appendicitis from January 2003 to September 2015. Patients were categorized by treatment: NOM, laparoscopic appendectomy (LA), and open appendectomy. A quasi-experimental analysis with interrupted time series examined the relationship between the year of admission and the likelihood of receiving NOM. Multivariable logistic regression analyses were used to evaluate the association between treatment strategy and patient outcomes. RESULTS: A total of 33,120 women satisfied the inclusion criteria. Respectively, 1070 (3.2%), 18,736 (56.6%), and 13,314 (40.2%) underwent NOM, LA, and open appendectomy. The NOM rate significantly increased between 2006 and 2015, with an annual increase of 13.9% (95% CI, 8.5-19.4, P <0.001). Compared with LA, NOM was significantly associated with higher rates of preterm abortion (odds ratio [OR]: 3.057, 95% CI, 2.210-4.229, P <0.001) and preterm labor/delivery (OR: 3.186, 95% CI, 2.326-4.365, P <0.001). Each day of delay to appendectomy was associated with significantly greater rates of preterm abortion (OR: 1.210, 95% CI, 1.123-1.303, P <0.001). CONCLUSIONS: Although NOM has been increasing as a treatment for pregnant patients with uncomplicated appendicitis, compared with LA, it is associated with worse clinical outcomes.

OBJECTIVE: To perform a cost-effectiveness analysis to examine the utility and effectiveness of OS performed at the time of elective cholecystectomy [laparoscopic cholecystectomy (LAP-CHOL)]. SUMMARY BACKGROUND DATA: OS has been adopted as a strategy to reduce the risk of ovarian cancer in women undergoing hysterectomy and tubal sterilization, although the procedure is rarely performed as a risk reducing strategy during other abdominopelvic procedures. METHODS: A decision model was created to examine women 40, 50, and 60 years of age undergoing LAP-CHOL with or without OS. The lifetime risk of ovarian cancer was assumed to be 1.17%, 1.09%, and 0.92% for women age 40, 50, and 60 years, respectively. OS was estimated to provide a 65% reduction in the risk of ovarian cancer and to require 30 additional minutes of operative time. We estimated the cost, quality-adjusted life-years, ovarian cancer cases and deaths prevented with OS. RESULTS: The additional cost of OS at LAP-CHOL ranged from $1898 to 1978. In a cohort of 5000 women, OS reduced the number of ovarian cancer cases by 39, 36, and 30 cases and deaths by 12, 14, and 16 in the age 40-, 50-, and 60-year-old cohorts, respectively. OS during LAP-CHOL was cost-effective, with incremental cost-effectiveness ratio of $11,162 to 26,463 in the 3 age models. In a probabilistic sensitivity analysis, incremental cost-effectiveness ratio for OS were less than $100,000 per quality-adjusted life-years in 90.5% or more of 1000 simulations. CONCLUSIONS: OS at the time of LAP-CHOL may be a cost-effective strategy to prevent ovarian cancer among average risk women.

Chronic white adipose tissue (WAT) inflammation has been recognized as a critical early event in the pathogenesis of obesity-related disorders. This process is characterized by the increased residency of proinflammatory M1 macrophages in WAT. However, the lack of an isogenic human macrophage-adipocyte model has limited biological studies and drug discovery efforts, highlighting the need for human stem cell-based approaches. Here, human induced pluripotent stem cell (iPSC) derived macrophages (iMACs) and adipocytes (iADIPOs) are cocultured in a microphysiological system (MPS). iMACs migrate toward and infiltrate into the 3D iADIPOs cluster to form crown-like structures (CLSs)-like morphology around damaged iADIPOs, recreating classic histological features of WAT inflammation seen in obesity. Significantly more CLS-like morphologies formed in aged and palmitic acid-treated iMAC-iADIPO-MPS, showing the ability to mimic inflammatory severity. Importantly, M1 (proinflammatory) but not M2 (tissue repair) iMACs induced insulin resistance and dysregulated lipolysis in iADIPOs. Both RNAseq and cytokines analyses revealed a reciprocal proinflammatory loop in the interactions of M1 iMACs and iADIPOs. This iMAC-iADIPO-MPS thus successfully recreates pathological conditions of chronically inflamed human WAT, opening a door to study the dynamic inflammatory progression and identify clinically relevant therapies.

Many studies have highlighted the difficulty inherent to the clinical application of fundamental neuroscience knowledge based on machine learning techniques. It is difficult to generalize machine learning brain markers to the data acquired from independent imaging sites, mainly due to large site differences in functional magnetic resonance imaging. We address the difficulty of finding a generalizable marker of major depressive disorder (MDD) that would distinguish patients from healthy controls based on resting-state functional connectivity patterns. For the discovery dataset with 713 participants from 4 imaging sites, we removed site differences using our recently developed harmonization method and developed a machine learning MDD classifier. The classifier achieved an approximately 70% generalization accuracy for an independent validation dataset with 521 participants from 5 different imaging sites. The successful generalization to a perfectly independent dataset acquired from multiple imaging sites is novel and ensures scientific reproducibility and clinical applicability.
