Purpose: Screening guidelines for breast cancer (BC) in transgender male (TM) patients are not well defined. This study describes referral patterns and compliance with referral for BC screening among TM patients receiving care at a tertiary care center. Methods: This was a retrospective cohort study of TM patients, 40–74 years of age, presenting for care between 2017 and 2020. The electronic medical record was queried for medical history and cancer screening data. Compliance with referral and screening was defined as occurring within 2 years of when screening would be expected. Results: Of the 266 patients identified, 45 met inclusion criteria. One (2.2%) had a history of BC, 0 (0%) had hereditary BC risk, and 11 (24.4%) had a family history of BC. Of the patients, 18 (40%) were referred for BC screening, of whom 13 (72.2%) were compliant with screening. Ten (55.6%) were referred by a primary care provider, 2 (11.1%) were referred by a transgender medicine specialist, and 6 (33.3%) were referred by both. Of the cohort, 27 (60%) had undergone masculinizing mastectomy. Six (22.2%) of these patients were referred for screening, of whom 0 (0%) had pre-screening clinical findings indicating need for screening. Of the 18 (40%) patients who had not undergone masculinizing mastectomy, 12 (66.7%) were referred for BC screening. Conclusions: There was heterogeneity in referral patterns for BC screening between TM patients who had undergone masculinizing mastectomy and those who had not. BC screening guidelines should be established for TM patients who have undergone masculinizing mastectomy. [ABSTRACT FROM AUTHOR]

The ketogenic diet (KD) is hypothesized to impact tumor progression by altering tumor metabolism. In this study, we assessed the impact of an unrestricted KD on epithelial ovarian cancer (EOC) tumor growth, gene expression, and metabolite concentration in a mouse model. ID8 EOC cells, which were syngeneic with C57Bl/6J mouse strain and transfected with luciferase (ID8-luc), were injectedand monitored for tumor development. Female mice were fed either a strict KD, a high fat/low carbohydrate (HF/LC) diet, or a low fat/high carbohydrate (LF/HC) diet (n = 10 mice per group) ad libitum. EOC tumor growth was monitored weekly, and tumor burden was determined based on luciferase fluorescence (photons/second). At the endpoint (42 days), tumors were collected and processed for RNA sequencing. Plasma and tumor metabolites were evaluated using LC-MS. The KD-fed mice exhibited a statistically significant increase in tumor progression in comparison to the HF/LC- and LF/HC-fed groups (9.1 vs. 2.0 vs. 3.1-fold, respectively, p < 0.001). The EOC tumors of the KD-fed mice exhibited significant enrichment of the peroxisome proliferator-activated receptor (PPAR) signaling and fatty acid metabolism pathways based on the RNA sequencing analysis when compared to the LF/HC- and HF/LC-fed mice. Thus, unrestricted KD diet enhanced tumor progression in our mouse EOC model. KD was associated with the upregulation of fatty acid metabolism and regulation pathways, as well as enrichment of fatty acid and glutamine metabolites. [ABSTRACT FROM AUTHOR]

Objective:  This study aimed to identify risk factors for postpartum readmission (PPR) in class 3 obese patients undergoing unscheduled cesarean deliveries., Study Design:  Retrospective cohort study of patients with a body mass index (BMI) of ≥40 kg/m 2 undergoing unscheduled cesarean delivery from 2017 to 2020 comparing patients with and without PPR (unexpected admission, emergency room/overnight observation visit, unscheduled outpatient visit, or ambulatory surgery within 30 days). Medical history, operative data, and postpartum outcomes were compared between the cohorts., Results:  The electronic medical record was queried to identify cesarean deliveries documented as "unscheduled." In total, 255 of 1,273 identified patients (20.0%) had a PPR. Median BMI was similar between the cohorts (44.2 kg/m 2 , interquartile range [IQR]: [41.8, 47.9] vs. 44.8 kg/m 2 [42.0, 48.9], p  = 0.066). Readmitted patients were more likely to have a history of smoking during or prior to pregnancy ( p  = 0.046). A subgroup exploratory analysis excluding outpatient and emergency room visits demonstrated higher rates of type II diabetes mellitus in patients with PPR (11.5 vs. 4.6%, p  = 0.030). Patients with readmission in comparison to those without readmissions were less likely to receive cefazolin prophylaxis (78.0 vs. 84.3%, p  = 0.014) in comparison to gentamicin/clindamycin prophylaxis. Patients with readmission were less likely to have had vaginal preparation (56.9 vs. 64.3%, p  = 0.027). On multivariable logistic regression analysis, smoking history (odds ratio [OR] = 1.44, 95% confidence interval [CI]: 1.06-1.96, p  = 0.0220) and hypertensive disease (OR = 1.57, 95% CI: 1.18-2.09, p  = 0.002) were associated with readmission. Cefazolin preoperative prophylaxis (OR = 0.59, 95% CI: 0.41-0.84, p  = 0.004) and vaginal sterile preparation (OR = 0.72, 95% CI: 0.54-0.95, p  = 0.022) were associated with decreased risk of readmission., Conclusion:  In class 3 obese patients, a history of smoking and a diagnosis of hypertensive disease are associated with an increased risk of PPR. Perioperative antibiotic prophylaxis with cefazolin along with vaginal sterile preparation associate with a decreased risk of PPR., Key Points: · Class 3 obesity and unscheduled cesarean deliveries are high risks for postpartum complications.. · Hypertensive disorders and smoking are associated with PPR.. · Cefazolin prophylaxis and vaginal preparation are associated with decreased PPR.., Competing Interests: None declared., (Thieme.

Objective: Ovarian cancer is associated with a high rate of venous thromboembolism. Our objective is to report the incidence of venous thromboembolism in recurrent ovarian cancer, assess the impact on morbidity and mortality, and evaluate predictors of venous thromboembolism., Methods: A retrospective single institution cohort study was performed. Patients with a diagnosis of recurrent ovarian cancer between 2007 and 2020 and no previous history of venous thromboembolism were identified. Demographic and clinical variables were collected. Univariate and multivariable analyses were performed to identify predictors of venous thromboembolism., Results: Of the 345 patients included in this study, 77 (22.3%) developed a venous thromboembolism. Most (n=56, 72.7%) were actively receiving treatment at the time of diagnosis of venous thromboembolism, of whom 44 (78.6%) had received three or more lines of treatment. In total, 42 (54.5%) were admitted to hospital on diagnosis and one mortality (1.3%) occurred secondary to venous thromboembolism. An intermediate/high risk Khorana score was not predictive of venous thromboembolism (p=0.24). The risk of venous thromboembolism was significantly higher with increasing lines of chemotherapy (odds ratio 1.14, 95% confidence interval 1.02 to 1.28 per line, p=0.026). There was no significant difference in overall survival (62.9 vs 49.1 median months, p=0.29) between patients with and without venous thromboembolism., Conclusions: More than 20% of patients with recurrent ovarian cancer developed a venous thromboembolism, and most occurred after three or more lines of treatment. The risk of venous thromboembolism was higher with increasing lines of chemotherapy. While venous thromboembolism did not appear to impact survival in this population, nearly half required hospitalization, emphasizing the morbidity of venous thromboembolism and potential impact on healthcare costs. Further studies are needed to improve risk stratification for venous thromboembolism in this high risk population., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2024.

Objective: Perioperative antibiotic prophylaxis reduces cesarean wound complications. This study investigates whether integration of standard-dose (500 mg) azithromycin prophylaxis reduced wound complications in patients with class III obesity (body mass index [BMI] ≥ 40 kg/m 2 ) undergoing unscheduled cesarean delivery., Study Design: Retrospective cohort study of patients with class III obesity undergoing unscheduled cesarean delivery in single hospital system from January 1, 2017, to January 1, 2020. A standard dose (500 mg) of azithromycin was integrated into system order sets in 2018. Medical history and postoperative wound outcomes were compared in pre- and postintegration cohorts. Wound complication was defined as composite of wound seroma, hematoma, superficial or deep infection., Results: A total of 1,273 patients met inclusion criteria, 303 patients in the preorder set group, and 970 patients in the postorder set group. Demographics were similar between the pre- and postintegration cohorts, including BMI (median: 44.4 kg/m 2 , p  = 0.84) and weight at delivery (mean: 121.2 ± 17.8 kg, p  = 0.57). Patients in the postintegration cohort had lower rates of composite postpartum wound complication (7.9 vs. 13.9%, p  = 0.002), superficial infection or deep infection/abscess (6.7 vs. 10.2%, p  = 0.042), and postpartum readmission or unscheduled visits (18.7 vs. 24.4%, p  < 0.029). Rates of chorioamnionitis and endometritis were similar between the pre- and postintegration groups (8.6 vs. 6.9%, p  = 0.33, and 1.7 vs. 1.9%, p  = 0.81, respectively). Patients in the postintegration cohort had lower risk of postoperative composite wound complication (unadjusted odds ratio [OR]: 0.54, confidence interval [CI]: 0.36-0.80, p  = 0.002) and lower rates of wound infection (unadjusted OR: 0.63, 95% CI: 0.40-0.99, p  = 0.044). When comparing patients who received azithromycin at delivery and patients who did not, standard-dose azithromycin reduced risk of postoperative wound complication (unadjusted OR: 0.67, 95% CI: 0.46-0.99, p  = 0.043)., Conclusion: A standard dose of azithromycin provides adequate perioperative prophylaxis in class III obese patients, decreasing rates of postcesarean wound complications and unscheduled postpartum outpatient visits., Key Points: · Class III obese patients undergoing unscheduled cesarean have high rates of wound complications.. · Standard-dose azithromycin reduces risk of postcesarean wound infection in class III obese patients.. · Standard-dose azithromycin reduces readmission, unscheduled visits in class III obese patients.., Competing Interests: None declared., (Thieme.
