Abstract Biomarkers that aid in early detection of neurodegeneration are needed to enable early symptomatic treatment and enable identification of people who may benefit from neuroprotective interventions. Increasing evidence suggests that sleep biomarkers may be useful, given the bi-directional relationship between sleep and neurodegeneration and the prominence of sleep disturbances and altered sleep architectural characteristics in several neurodegenerative disorders. This study aimed to demonstrate that sleep can accurately characterize specific neurodegenerative disorders (NDD). A four-class machine-learning algorithm was trained using age and nine sleep biomarkers from patients with clinically-diagnosed manifest and prodromal NDDs, including Alzheimer’s disease dementia (AD = 27), Lewy body dementia (LBD = 18), and isolated REM sleep behavior disorder (iRBD = 15), as well as a control group (CG = 58). The algorithm was validated in a total of 381 recordings, which included the training data set plus an additional AD = 10, iRBD = 18, Parkinson disease without dementia (PD = 29), mild cognitive impairment (MCI = 78) and CG = 128. Test-retest consistency was then assessed in LBD = 10, AD = 9, and CG = 46. The agreement between the NDD profiles and their respective clinical diagnoses exceeded 75% for the AD, LBD, and CG, and improved when NDD participants classified Likely Normal with NDD indications consistent with their clinical diagnosis were considered. Profiles for iRBD, PD and MCI participants were consistent with the heterogeneity of disease severities, with the majority of overt disagreements explained by normal sleep characterization in 27% of iRBD, 21% of PD, and 26% of MCI participants. For test-retest assignments, the same or similar NDD profiles were obtained for 88% of LBD, 86% in AD, and 98% of CG participants. The potential utility for NDD subtyping based on sleep biomarkers demonstrates promise and requires further prospective development and validation in larger NDD cohorts.

Abstract In the United States, over 2 million individuals openly identify with a gender that differs from their sex assigned at birth. A cancer diagnosis is physically and psychologically taxing—and, in some, traumatic. However, for transgender and gender‐diverse (TGD) people, many of whom have experienced discrimination in myriad health care settings, the challenges may be even greater. These recommendations focus on how best to deliver quality cancer care to transgender men (individuals who identify as men but were assigned female sex at birth), transgender women (individuals who identify as women but were assigned male sex at birth), and people who identify somewhere beyond this gender spectrum as nonbinary or using other terms, based on the available, albeit sparse, literature. This review broaches: (1) the epidemiology of cancer in TGD individuals, including the incidence of cancer and cancer‐related mortality; (2) cancer center practices that are welcoming and affirming to TGD patients; (3) the need for awareness and intentionality in the spaces of diagnosis and treatment for cancer; (4) the inevitable conclusion that gender differences exist but much more needs to be learned about the impact of gender‐affirming therapy, consisting of gender‐affirming surgeries and gender‐affirming hormone therapy, on cancer therapy; and (5) the efficacy and perceived safety of antineoplastic therapy and gender‐affirming hormone therapy.

Background and Objectives: The epidemiological data regarding mortality rates of adults with sarcoidosis and non-ischemic cardiovascular disease (CVD) are limited. A retrospective observational analysis was conducted to identify trends and disparities related to sarcoidosis and non-ischemic cardiovascular disease mortality among the adult US population from 1999 to 2022. Methods: We used the Centers for Disease Control and Prevention (CDC) WONDER database to extract death certificate data for the adult US population (≥25 years). The age-adjusted mortality rates (AAMRs) per 100,000 persons were calculated, and annual percent changes (APCs) were determined using Joinpoint. Results: Between 1999 and 2022, 23,642 deaths were identified related to non-ischemic CVD + sarcoidosis. The overall AAMR increased from 0.2 (95% CI, 0.2 to 0.3) in 1999 to 0.5 (95% CI, 0.5 to 0.6) in 2022. Females had a higher AAMR than males (0.6 vs. 0.5). Non-Hispanic (NH) blacks had the highest AAMR, followed by NH whites and Hispanic or Latinos. The southern region had the highest AAMR (0.7: 95% CI, 0.6–0.7), followed by the Midwest (0.6, 95% CI, 0.54–0.669), the Northeast (0.5, 95% CI, 0.5 to 0.6), and the West (0.4; 95% CI, 0.3–0.4). Urban and rural areas had comparable mortality rates (0.5 vs. 0.6). People aged 65+ had the highest AAMRs. Conclusions: The overall mortality rates for non-ischemic CVD and sarcoidosis have increased in the US from 1999 to 2022. Females and NH blacks had higher AAMRs, while a minimal variation was observed based on geographical regions. Early diagnosis and prompt management are the keys to reducing the mortality burden of non-ischemic CVD plus sarcoidosis.

Abstract Endometriosis is defined as the presence of endometrial-like glands and stroma outside of the uterus. There are three types of endometriotic lesions: superficial or peritoneal endometriosis, ovarian endometrioma, and deep infiltrating disease. Endometriosis not only occurs in the pelvis but also can be found in extrapelvic sites such as the gastrointestinal tract, upper abdominal viscera, genitourinary tract, abdominal wall, diaphragm, and thoracic cavity. After thorough history and physical examination is performed, imaging, such as ultrasound or magnetic resonance imaging (MRI), should be obtained if there is high suspicion for deep-infiltrating endometriosis to better assess visceral involvement. Endometriosis can be suspected based on symptoms, physical examination findings, and imaging. However, a definitive diagnosis requires histopathologic confirmation. Treatment options include expectant, medical, and surgical management. Endometriosis is largely a quality-of-life issue, and treatment should be tailored accordingly with empiric medical therapy frequently utilized. Medical management focuses on symptom improvement. Surgical management with excision of endometriosis is preferred over ablation or fulguration of endometriotic lesions. In the case of deep or extrapelvic endometriosis, treatment with a multidisciplinary team with experience in the treatment of advanced-stage endometriosis is essential to minimizing morbidity and increasing long-term success.

BACKGROUND: Patients with Fontan palliation have reduced aerobic capacity because of impaired cardiac, pulmonary, and skeletal muscle function. However, the assessment of aerobic capacity in this population still relies on comparisons with people without cardiovascular disease rather than comparison with the expected aerobic capacity of other Fontan patients. The purpose of this study was to determine the expected aerobic capacity of adults with Fontan palliation. METHODS: Adults with Fontan palliation who underwent a cardiopulmonary exercise test at Mayo Clinic (2003–2023) were stratified into quartiles based on the predicted peak oxygen consumption (VO 2 ). We assessed the correlates of predicted peak VO 2 and the relationship between predicted peak VO 2 quartiles and cardiovascular outcomes (death/transplant). RESULTS: Of 323 patients (age, 29±9 years; 177 [55%] men), the median peak VO 2 was 19.1 (15.2–23.9) mL/kg per minute, and this corresponds to a predicted peak VO 2 of 51% (range, 19–88; interquartile range, 41–62). After multivariable adjustments, the correlates of predicted peak VO 2 were body mass index (β±SE, −2.61±0.95; 2.61% decrease in predicted peak VO 2 per 5 kg/m 2 increase in body mass index; P =0.009), systemic saturation (β±SE, 3.65±0.85; 3.65% increase in predicted peak VO 2 per 5% increase in oxygen saturation; P <0.001), and Fontan pressure (β±SE, −1.24±0.22; 1.24% decrease in predicted peak VO 2 per 1 mm Hg increase in Fontan pressures; P <0.001). There was a 47% increase in the risk for death/transplant from a higher predicted peak VO 2 quartile to the next lower quartile (adjusted hazard ratio, 1.47 [95% CI, 1.09–2.05]; P =0.01). CONCLUSIONS: The results of the current study would help calibrate the interpretation of exercise test data in adults with Fontan palliation and improve risk stratification in this population. It also underscores the need to maintain normal Fontan hemodynamics and body weight, which are important determinants of aerobic capacity.

Abstract Introduction: Total hip arthroplasty (THA) is increasingly used in less severe cases of hip osteoarthritis (OA).This paper aimed to determine 1) The prevalence of different degrees of OA before THA, 2) The association of pre-operative OA severity with the severity of baseline symptoms and 3) The association of pre-operative OA severity with outcomes post-THA. Methods: A retrospective study of a prospective database of all THAs at two tertiary academic centers between 2020 and 2021 was conducted. There were 803 patients in the database, with 109 being excluded due to incomplete data. There were 694 patients included, and the mean age and body mass index were 64.50±12.80 years and 28.45±5.90 kg/m2, respectively. Most patients were women (n=361; 52.0%). Radiographic analysis was performed to assess the degree of hip OA with the Tönnis grade (0 – 3; no OA – complete degradation). Patients had pre-operative patient-reported outcome measures (PROMs) of hip function via the Oxford Hip Score (OHS) and their overall well-being via the EQ-5D-5L, with follow-up and post-operative PROMs 12 months after surgery. Data analysis was performed using SPSS (IBM, Armonk, NY). Results: There were no differences in pre-operative OHS between Tönnis groups (18±6.26, n=14 in Tönnis 1, 21.19±8.27, n=260 in Tönnis 2 and 18.18±7.09, n=420 in Tönnis 3, p=0.14) After one year, the increase in OHS was 18.03±11.95, 18.32±10.96, and 24.32±9.98, respectively for Tönnis 1,2, and 3 (p<0.001). Thus, the percentage meeting the patient acceptable symptom state (PASS) was 57.1%, 60.8% and 72.6%. One year EQ-5D-5L was also highest in Tönnis 3 (47.5 ± 4.03, 79.6 ± 13.25 and 82.12 ± 11.67, p<0.001). Conclusion: The highest-grade OA before THA was correlated with the greatest improvements in hip function and quality of life. This study demonstrates that a conservative approach and re-education should be attempted in patients who have an absence of advanced radiographic OA.
