Objective And Methods: Prednisone and its active metabolite prednisolone, both substrates for 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2), may represent a pharmacological challenge for the enzyme. The aim of the present work was to define the possible role of abnormal cortisol/cortisone handling, as revealed by an urinary tetrahydrocortisol + allotetrahydrocortisol (THFs)/tetrahydrocortisone (THE) ratio between 1.5 and 3.0, by measuring urinary cortisol and cortisone metabolites in: normotensive individuals (n = 100) who received 7-8 mg/day of oral prednisone and were then followed for development of hypertension; essential hypertensive (EH) participants from primary care (n = 103); and EH hypertensive patients referred to the Hypertension Unit (n = 141).
Results: About one-third (14 out of 47, 30%) of glucorticoid-treated patients who developed hypertension showed a THFs/THE ratio >1.5, which was seen in 3% (n = 3) and 14% (n = 19) of primary and tertiary care hypertensive patients, respectively. A THFs/THE ratio >1.5 was associated with a 3.8-fold incremental risk of hypertension after glucocorticoid therapy, regardless of duration and intensity of prednisone therapy.
Conclusions: A number of EH patients and glucocorticoid-treated participants shared a similar phenotype, characterized by both arterial hypertension and elevated urinary THFs/THE ratio. Such a phenotype is more common in severely, rather than in mildly, hypertensive patients.

Objectives: To describe the clinical profile and compare the long-term outcomes of patients with S-PAN treated with various treatment regimens at our centre in the last 2 decades.
Methods: Data regarding clinical presentation, treatment allocation, relapses and outcomes of patients fulfilling American College of Rheumatology (ACR) 1990 criteria for PAN in the last 2 decades were recorded from electronic medical records. Relapse-free survival and predictors were analysed using KM survival statistics and regression analysis.

Antibody-mediated rejection (AMR) remains a major complication after solid organ transplantation (SOT). Current treatment options are inefficient and result in drastic impairment of the general immunity. To selectively eliminate responsible alloreactive B cells characterized by anti-donor-HLA B-cell receptors (BCRs), we generated T cells overcoming rejection by antibodies (CORA-Ts) engineered with a novel chimeric receptor comprising a truncated donor-HLA molecule as antigen recognition domain.

Background: Age-related macular degeneration (AMD) decrease vision and presents considerable challenges for both public health and clinical management strategies. Obesity is usually implicated with increased AMD, and body mass index (BMI) does not reflect body fat distribution. An array of studies has indicated a robust relationship between body fat distribution and obesity.

Objective: Constructing a predictive model for the occurrence of heart disease in elderly hypertensive individuals, aiming to provide early risk identification.
Methods: A total of 934 participants aged 60 and above from the China Health and Retirement Longitudinal Study with a 7-year follow-up (2011-2018) were included. Machine learning methods (logistic regression, XGBoost, DNN) were employed to build a model predicting heart disease risk in hypertensive patients.

Background: Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder affecting multiple systems. However, arterial stenosis is a rare manifestation in patients with NF1. Since the symptoms of arterial stenosis caused by NF1 are often atypical and have a high under-diagnosis rate, this can lead to serious complications such as hypertension, ischemic stroke, or even death.
