There is a paucity of data on the impact of cold ischemia time before the initiation of normothermic machine perfusion (NMP), particularly in more susceptible organs such as livers from donation after circulatory death (DCD) donors. The present analysis aimed to investigate the impact of prolonged time from cross-clamp until NMP start on early allograft dysfunction and other peri–liver transplant (LT) outcomes. All DCD LT performed and placed on NMP at Mayo Clinic Arizona, Florida, and Rochester from January 2022 to March 2024 were included. The decision was made a priori to divide the population into 2 groups based on terciles: typical cross-clamp to on-pump time (lower 2 terciles) versus prolonged cross-clamp to on-pump time (upper tercile; >2 h 45.6 min). Three hundred eighty-four DCD LT undergoing NMP met the inclusion criteria. The rate of early allograft dysfunction was significantly higher in the prolonged cross-clamp to on-pump group (51.2%) compared to the typical cross-clamp to on-pump group (37.6%) (p = 0.01). The prolonged cross-clamp to on-pump group also had higher rates of acute kidney injury and the number of packed red blood cells transfused during LT. No significant difference in ischemic cholangiopathy (2.4% vs. 3.1%; p = 0.68) or graft survival at 12 months was seen between the prolonged cross-clamp to on-pump and typical cross-clamp to on-pump group, respectively. Following cross-clamp, DCD liver grafts should be placed on the NMP pump as quickly as is safely and logistically possible. In cases where delays are unavoidable, such as waiting for biopsy results or liver reallocation with another center, acceptable results can still be achieved, and therefore, livers with prolonged times should still be used.

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.
