Metabolic Syndrome, Kidney-Related Adiposity, and Kidney Microcirculation: Unraveling the Damage.

Biomedicines

November 2024

Division of Nephrology and Research Institute for Convergence of Biomedical Science and Technology, Pusan National University Yangsan Hospital, Yangsan 50612, Republic of Korea.

Metabolic syndrome (MetS) is a cluster of interrelated risk factors, including insulin resistance, hypertension, dyslipidemia, and visceral adiposity, all of which contribute to kidney microvascular injury and the progression of chronic kidney disease (CKD). However, the specific impact of each component of MetS on kidney microcirculation remains unclear. Given the increasing prevalence of obesity, understanding how visceral fat-particularly fat surrounding the kidneys-affects kidney microcirculation is critical.

Article Synopsis
  • Residential smoking cessation therapy can significantly aid heavy smokers, especially those with high dependence and health issues needing immediate intervention.
  • Changes in participants' thoughts and feelings about smoking during therapy relate to their success in quitting, with factors like age and coping strategies playing a key role.
  • Successful quitters tended to have better emotion regulation strategies and a stronger negative perception of smoking's effects, indicating these psychological aspects are critical to cessation outcomes.

The pathogenesis of gout.

J Rheum Dis

January 2025

Division of Rheumatology, Department of Internal Medicine, Pusan National University Yangsan Hospital, Pusan National University School of Medicine, Yangsan, Korea.

Gout is the most common inflammatory arthritis in adults, associated with hyperuricemia and the chronic deposition of monosodium urate (MSU) crystals. Hyperuricemia results from increased production of uric acid and decreased excretion by the kidneys and intestines. Urate excretion is regulated by a group of urate transporters, and decreased renal or intestinal excretion is the primary mechanism of hyperuricemia in most people.
