Primary biliary cholangitis (PBC) is a chronic inflammatory disease of the small intrahepatic bile ducts disproportionally affecting women. Timely diagnosis and treatment can often prevent progression to liver cirrhosis. We hypothesized PBC diagnosis in male patients is delayed and prognosis impaired. We, therefore, conducted a case-control study and compared clinical and prognostic features among male and female patients with PBC. 49 male patients with PBC treated at a German tertiary care center between 2006 and 2017 were identified and compared to 98 age-matched female controls. Prospectively collected clinical/biochemical data were analyzed retrospectively. Liver biopsies were scored in a blinded fashion. Prognostic parameters were calculated using established prognostic scores (GLOBE, PBC-UKE). Statistical analysis was performed using Mann-Whitney test and Fisher´s exact test. At PBC diagnosis, male patients reported significantly less PBC-associated symptoms as compared to female controls (34 versus 71%,  < .01). Compared to female patients, median time from onset of PBC-related symptoms and/or first reported elevated cholestatic biochemical parameters to PBC diagnosis was significantly increased in men (36 versus 12 months,  = .02). In addition, male patients underwent liver biopsy to establish PBC diagnosis more frequently, tended to show more advanced fibrosis and showed significantly poorer prognostic PBC score results. Hepatocellular carcinoma was only observed in male patients ( = 3). When compared to women, men with PBC suffer from less PBC-related symptoms, receive PBC diagnosis delayed and have a worse prognosis. Despite its rarity, the diagnosis of PBC should be considered in men with elevated cholestatic parameters.

Background: Patients with chronic kidney disease and their families request early and continuous advance care planning. Based on user involvement, an advance care planning intervention was developed to support patients, family members and healthcare professionals (HCPs) in advance care planning conversations in a nephrology outpatient setting.

Objective: To explore the experiences and perceptions of an advance care planning intervention among patients with chronic kidney disease, family members and healthcare professionals.

Objectives: We aimed to characterize a craniofacial skeletal phenotype (CSP) of adult obstructive sleep apnea (OSA) patients from a multidimensional perspective, exploring the impact of transverse skeletal discrepancy (TSD) on multivariable polysomnographic profiles.

Materials And Methods: This retrospective, cross-sectional study included 102 adult OSA patients. Sagittal, vertical, and transverse skeletal patterns were categorized on the cone beam computed tomography images.

Introduction: Mitochondria and angiogenesis play key roles in multiple myeloma (MM) development, but their interrelated genes affecting MM prognosis are under-studied.

Methods: We analyzed TCGA_MMRF and GSE4581 datasets to identify four genes - CCNB1, CDC25C, HSP90AA1, and PARP1 - that significantly correlate with MM prognosis, with high expression indicating poor outcomes.

Results: A prognostic signature based on these genes stratified patients into high- and low-risk groups, with the latter showing better survival.

Objective: This study focuses on how patients experience the time following amputation after primary limb salvage surgery due to musculoskeletal malignancies. Limb salvage is state of the art in the treatment of musculoskeletal tumours. Nonetheless, in some cases, limb salvage can become problematic over time, resulting in poorer limb function and septic outcomes.

Borderline personality disorder (BPD) has a strong impact not only on patients' lives but also on their families. The presence of an invalidating environment is one of the key factors in the etiology of BPD. This study evaluated the impact of the Family connections (FC) program on burden, grief, and other clinical variables in 202 caregivers and identified the profiles of participants who improved/deteriorated their levels of burden and grief.
