Abstract
OBJECTIVE To assess population-level trends, characteristics, and outcomes of high-grade serous tubo-ovarian carcinoma in the United States. METHODS This retrospective cohort study queried the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. The study population was 27,811 patients diagnosed with high-grade serous tubo-ovarian carcinoma from 2004 to 2020. The exposure was the primary cancer site (ovary or fallopian tube). Main outcome measures were temporal trends, clinical characteristics, and overall survival associated with primary cancer site assessed in multivariable analysis. RESULTS The study population comprised 23,967 diagnoses of high-grade serous ovarian carcinoma and 3,844 diagnoses of high-grade serous fallopian tubal carcinoma. The proportion of diagnoses of high-grade serous fallopian tubal carcinoma increased from 365 of 7,305 (5.0%) in 2004-2008 to 1,742 of 6,663 (26.1%) in 2017-2020. This increase was independent in a multivariable analysis (adjusted odds ratio [aOR] vs 2004-2008, 2.28 [95% CI, 1.98-2.62], 3.27 [95% CI, 2.86-3.74], and 6.65 [95% CI, 5.84-7.57] for 2009-2012, 2013-2016, and 2017-2020, respectively). This increase in high-grade serous fallopian tubal carcinoma was seen across age groups (4.3-5.8% to 22.7-28.3%) and across racial and ethnic groups (4.1-6.0% to 21.9-27.5%) (all P for trend <.001). Among the cases of tumors smaller than 1.5 cm, the increase was particularly high (16.9-67.6%, P for trend <.001). Primary-site tumors in the high-grade serous fallopian tubal carcinoma group were more likely to be smaller than 1.5 cm (aOR 8.26, 95% CI, 7.35-9.28) and unilateral (aOR 7.22, 95% CI, 6.54-7.96) compared with those in high-grade serous ovarian carcinoma. At the cohort level, the diagnosis shift to high-grade serous fallopian tubal carcinoma was associated with narrowing differences in survival over time between the two malignancy groups: adjusted hazard ratio 0.84 (95% CI, 0.74-0.96), 0.91 (95% CI, 0.82-1.01), 1.01 (95% CI, 0.92-1.12), and 1.12 (95% CI, 0.98-1.29) for 2004-2008, 2009-2012, 2013-2016, and 2017-2020, respectively. CONCLUSION This population-based assessment suggests that diagnoses of high-grade serous tubo-ovarian carcinoma in the United States have been rapidly shifting from high-grade serous ovarian to fallopian tubal carcinoma in recent years, particularly in cases of smaller, unilateral tumors.

Abstract
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.

Abstract
OBJECTIVE To assess national-level trends, characteristics, and outcomes of pregnancies with Turner syndrome in the United States. DESIGN Cross-sectional study. SETTING The Healthcare Cost and Utilization Project's National Inpatient Sample. SUBJECTS A total of 17,865,495 hospital deliveries from 2016-2020. EXPOSURE A diagnosis of Turner syndrome, identified according to the World Health Organization's International Classification of Disease 10th revision code of Q96. MAIN OUTCOME MEASURES Obstetrics outcomes related to Turner syndrome, assessed with inverse probability of treatment weighting cohort and multivariable binary logistic regression modeling. RESULTS The prevalence of pregnant patients with Turner syndrome was 7.0 per 100,000 deliveries (one in 14,235). The number of hospital deliveries with patients who have a diagnosis of Turner syndrome increased from 5.0 to 11.7 per 100,000 deliveries during the study period (adjusted-odds ratio [aOR] for 2020 vs. 2016; 2.18, 95% confidence interval [CI] 1.83-2.60). Pregnant patients with Turner syndrome were more likely to have a diagnosis of pregestational hypertension (4.8% vs. 2.8%; aOR 1.65; 95% CI 1.26-2.15), uterine anomaly (1.6% vs. 0.4%; aOR, 3.01; 95% CI 1.93-4.69), and prior pregnancy losses (1.6% vs. 0.3%; aOR 4.70; 95% CI 3.01-7.32) compared with those without Turner syndrome. For the index obstetric characteristics, Turner syndrome was associated with an increased risk of intrauterine fetal demise (10.9% vs. 0.7%; aOR 8.40; 95% CI 5.30-13.30), intrauterine growth restriction (8.5% vs. 3.5%; aOR 2.11; 95% CI 1.48-2.99), and placenta accreta spectrum (aOR 3.63; 95% CI 1.20-10.97). For delivery outcome, pregnant patients with Turner syndrome were more likely to undergo cesarean delivery (41.6% vs. 32.3%; aOR 1.53; 95% CI 1.26-1.87). Moreover, the odds of periviable delivery (22-25 weeks: 6.1% vs. 0.4%; aOR 5.88; 95% CI 3.47-9.98) and previable delivery (<22 weeks: 3.3% vs. 0.3%; aOR 2.87; 95% CI 1.45-5.69) were increased compared with those without Turner syndrome. CONCLUSIONS The results of contemporaneous, nationwide assessment in the United States suggest that although pregnancy with Turner syndrome is uncommon this may represent a high-risk group, particularly for intrauterine fetal demise and periviable delivery. Establishing a society-based approach for preconception counseling and antenatal follow-up would be clinically compelling.

Abstract
BACKGROUND Gallstone disease in pregnancy is one of the most common indications for nonobstetrical surgery during pregnancy. National-level data on contemporary surgical practice and outcomes are limited. OBJECTIVE This study aimed to assess the clinical characteristics and outcomes of patients undergoing cholecystectomy during pregnancy. STUDY DESIGN This cross-sectional study examined the Healthcare Cost and Utilization Project's 2 nationwide databases in the United States: the National Inpatient Sample and the Nationwide Ambulatory Surgery Sample. The study population included 18,630 patients who had cholecystectomy during pregnancy from January 2016 to December 2020. The exposure was gestational age, grouped sequentially into the following 5 groups: first trimester (<14 weeks), early second trimester (14-20 weeks), late second trimester (21-27 weeks), early third trimester (28-36 weeks), and late third trimester (≥37 weeks). The main outcomes were clinical demographics, medical comorbidities, surgical information, and pregnancy characteristics and outcomes, assessed by gestational age. RESULTS Cholecystectomy was most common in the early second trimester (32.1%), followed by the first trimester (25.2%), late second trimester (23.1%), early third trimester (12.4%), and late third trimester (7.2%). Patients in the first-trimester group were more likely to be aged ≥35 years, to smoke, and to have acute cholecystitis, severe hyperemesis gravidarum including metabolic disturbance, pregestational diabetes, multifetal gestation, and sepsis/shock (P<.001). Patients in the early-third-trimester group were more likely to be obese and have gestational diabetes, Charlson Comorbidity Index of ≥1, premature rupture of membranes, and intrauterine growth restriction, whereas those in the late-third-trimester group were more likely to have gallstone pancreatitis, biliary colic, chorioamnionitis, gestational hypertension, preeclampsia, and severe maternal morbidity including sepsis (P<.001). At the cohort level, a laparoscopic approach was used in most cholecystectomy procedures (97.5%), and bile duct injury was uncommon (<0.1%). Delivery during the admission occurred in 0.3%, 0%, 0.6%, 17.8%, and 60.6% in the 5 gestational age groups, respectively (P<.001). Among the cases that had delivery in the early- and late-third-trimester groups, the delivery event preceded cholecystectomy in 61.4% and 86.2%, respectively, whereas both delivery and cholecystectomy occurred on the same day in 34.3% and 13.8%, respectively. CONCLUSION This nationwide analysis suggests that clinical and pregnancy characteristics and outcomes of patients undergoing cholecystectomy differ by pregnancy stage with a bimodal distribution. Although patients in the first and third trimesters have distinct medical conditions, more clinically significant pregnancy and maternal outcomes were found in both groups compared with patients in the second trimester.

Abstract
OBJECTIVE To examine uptake, characteristics, and survival outcome of less-radical fertility-sparing surgery with cervical conization and lymph node evaluation (Cone-LN) in reproductive age patients with early cervical cancer. METHODS This retrospective cohort study examined the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. The study population included 407 patients aged <50 years with stage IA-IB2 (≤4 cm) cervical cancer who received fertility-sparing surgery from 2004 to 2019. The exposure was fertility-sparing surgery type: Cone-LN (n = 196) or trachelectomy with lymph node evaluation (Trach-LN, n = 211). The main co-outcomes were (i) temporal trends of surgery type, assessed with Cochran-Armitage test, and (ii) clinical and tumor characteristics, assessed with multivariable binary logistic regression model. The secondary outcome was overall survival, assessed with inverse probability of treatment weighting propensity score. RESULTS The number of patients receiving Cone-LN increased from 43.5% in 2004-2007 to 58.4% in 2016-2019 (P-trend = 0.005). Patients receiving conization and sentinel lymph node (SLN) biopsy alone increased from 0% to 14.4% (P-trend < 0.001). In a multivariable analysis, patients in the Cone-LN group were more likely to undergo SLN biopsy (aOR 6.04) compared to those in the Trach-LN group whereas those with adenocarcinoma (aOR 0.49) and T1b tumors (aOR for ≤2 cm 0.21, and aOR for 2.1-4.0 cm 0.10) were less likely to receive Cone-LN. In a propensity score-weighted model, the Cone-LN and Trach-LN groups had comparable overall survival (7-year rates, 98.9% vs 97.8%). Similar associations were observed for patients with squamous, adenocarcinoma / adenosquamous, T1a classification, and T1b(≤2 cm) classification. CONCLUSION The current population-based analysis suggests that the performance of cervical conization with lymph node evaluation, particularly with SLN biopsy, is gradually increasing for early cervical cancer patients desiring future fertility.

Abstract
Purpose In chronic obstructive pulmonary disease (COPD) some patients develop paradoxical inspiratory rib motion, which is termed Hoover's sign. Our objective was to determine whether Hoover's sign is associated with a difference in the maximal expiratory pressure (MEP), the maximal inspiratory pressure (MIP), the MEP/MIP ratio, and other features on pulmonary function tests (PFTs). Methods This observational prospective single-center cohort study enrolled patients with an established diagnosis of COPD with Global initiative for chronic Obstructive Lung Disease (GOLD) stage 3 (severe) and 4 (very severe) based on PFTs. Respiratory pressure measurements were also collected. Patients were examined for the presence or absence of Hoover's sign on physical examination by 2 internal medicine resident physicians trained in examining for Hoover's sign by a pulmonologist. Results A total of 71 patients were examined for the presence of Hoover's sign. Hoover's sign was present in 49.3% of patients. Observer agreement (k statistic) was 0.8 for Hoover's sign. Median MEP/MIP was significantly greater in patients with Hoover's sign than those without Hoover's sign (1.88 versus 1.16, p<0.001). Patients with Hoover's sign also had a significantly lower MIP (39.0 versus 58.0, p<0.001) and higher residual volume (RV) to total lung capacity (TLC) ratio indicating a higher degree of air trapping (65 versus 59.5, p<0.014). Conclusion The presence of Hoover's sign in patients with COPD is associated with a higher MEP/MIP ratio. This suggests respiratory pressure measurements can predict diaphragm dysfunction in patients with GOLD stage 3 and 4 COPD. Patients with Hoover's sign were also found to have a lower MIP and more air trapping.
