Chronic kidney disease (CKD) is a progressive condition that affects more than 10% of the population worldwide, accounting for more than 843 million (M) individuals. The prevalence of CKD (844 M patients) is higher than that of diabetes mellitus (422 M patients), cancer (42 M patients), and HIV (37 M patients), but people are often less aware of it. Global expert groups predict reductions in the nephrology workforce in the next decade, with a declining interest in nephrology careers. Over time, KDIGO guidelines have also focused on topics related to the prevention or management of CKD patients in real-life settings. On these premises, a new educational program with international experts in the field of nephrology took place from November 2022 until March 2023 in Milan, Italy. This multinational masterclass provided an educational platform providing unbiased education on diagnosis and treatment by sharing the most recent research data on CKD and comorbidities, therefore creating a snowball effect to increase the implementation of best practices worldwide, using examples from 'real-life' patient outcomes. This paper provides an overview of the International Nephrology Masterclass (INM) concept, summarizing the key lectures and discussions, and giving an outline of future key developments.

Background/Objectives: The complications of hypertension depend not only on the mean blood pressure (BP) but also on its variability (BPV). Recent studies suggest that the choroid may serve as an indicator of systemic vascular damage. These studies have been made possible by the increased availability of optical coherence tomography (OCT). The aim of our study was to analyze the relationship between short-term BP variability (STBPV) and choroid–retinal thickness in hypertensive patients. Methods: A total of 98 patients with a mean age of 49 ± 12 years were enrolled in the study. All participants underwent 24 h blood pressure (BP) monitoring to measure 24 h mean systolic (SBP) and diastolic blood pressure (DBP), along with their respective standard deviations (SD), the weighted SD of 24 h SBP and DBP, and the average real variability (ARV) of 24 h SBP and DBP. The choroid–retinal region was assessed using Swept-Source OCT, with choroidal thickness (ChT) and retinal thickness divided into three concentric rings, and their mean choroidal thickness (ChT-or) was calculated. Results: The choroidal thickness of the concentric rings was found to be inversely correlated with all ARV values of the monitored blood pressure means. In particular, a correlation was observed between the ARV of daytime DBP and ChT-or. This correlation remained statistically significant (β = −0.34; p = 0.02) even after adjustment for various confounding factors. The ARV of daytime DBP was the only STBPV index to maintain a significant association, in the multivariate analysis, with the central ring mean thickness (β = −0.314; p = 0.001) and the inner choroidal ring mean thickness (β = −0.262; p = 0.003). Conclusions: Our study demonstrated an independent negative association between short-term BP variability (STBPV), when expressed as ARV of daytime DBP, and choroidal thickness. This finding confirms the value of choroidal thickness as a marker of cardiovascular risk. [ABSTRACT FROM AUTHOR]

Hypertension is a major cardiovascular risk factor that is responsible for a heavy burden of morbidity and mortality worldwide. A critical aspect of cardiovascular risk estimation in hypertensive patients depends on the assessment of hypertension-mediated organ damage (HMOD), namely the generalized structural and functional changes in major organs induced by persistently elevated blood pressure values. The vasculature of the eye shares several common structural, functional, and embryological features with that of the heart, brain, and kidney. Since retinal microcirculation offers the unique advantage of being directly accessible to non-invasive and relatively simple investigation tools, there has been considerable interest in the development and modernization of techniques that allow the assessment of the retinal vessels' structural and functional features in health and disease. With the advent of artificial intelligence and the application of sophisticated physics technologies to human sciences, consistent steps forward have been made in the study of the ocular fundus as a privileged site for diagnostic and prognostic assessment of diverse disease conditions. In this narrative review, we will recapitulate the main ocular imaging techniques that are currently relevant from a clinical and/or research standpoint, with reference to their pathophysiological basis and their possible diagnostic and prognostic relevance. A possible non pharmacological approach to prevent the onset and progression of retinopathy in the presence of hypertension and related cardiovascular risk factors and diseases will also be discussed.
