However, the next turnaround was prompted by interpretation of the data from the Systolic Blood Pressure Intervention Trial (SPRINT) in 2015, which provided evidence for a lower rate of cardiovascular events when systolic blood pressure was lowered below 120 mm Hg. Since the SPRINT trial had excluded patients with diabetes, the Blood Pressure Control Target in Diabetes (BPROAD) trial (2025), which included diabetics, received major attention. The BPROAD trial came to similar conclusions as the SPRINT trial, now supporting the benefit of lowering systolic blood pressure below 120 mm Hg for a broader range of patients.

Beyond achieving substantial and sustained weight loss, these agents offer new opportunities to prevent and treat a broad range of obesity-related complications. At the same time, emerging diagnostic frameworks that move beyond the traditional body mass index (BMI)-based classification are prompting a reassessment of how obesity is defined and clinically stratified, with the aim of improving risk assessment and guiding treatment decisions.Recent evidence has also refined the diagnostic evaluation and management of adrenal incidentalomas and endocrine causes of hypertension. In parallel, the development of selective aldosterone synthase inhibitors introduces a potential new treatment option for primary aldosteronism, the most common cause of secondary hypertension.A similar paradigm shift is occurring in the management of thyroid nodules and thyroid cancer. Contemporary strategies increasingly emphasise risk-adapted diagnostic and therapeutic approaches that enable accurate identification of clinically significant disease while reducing overdiagnosis and unnecessary intervention. In patients with low-risk thyroid cancer, organ-preserving surgery, more selective use of radioiodine therapy, and, in carefully selected cases, active surveillance are increasingly incorporated into clinical practice. Collectively, these developments aim to reduce treatment-related morbidity while maintaining excellent oncological outcomes and preserving long-term quality of life.</p>","PeriodicalId":73385,"journal":{"name":"Innere Medizin (Heidelberg, Germany)","volume":" ","pages":"869-881"},"PeriodicalIF":0.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148451097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
