Abstract
OBJECTIVE The visit-to-visit variability (VVV) of blood pressure (BP) has been recognized as a risk factor for cardiovascular events and chronic kidney disease (CKD). The objective of this study is to valuate the association between the VVV of BP and changes in estimated glomerular filtration rate (eGFR) in elderly CKD patients at different stages of renal function. MATERIALS AND METHODS For 60 months, we analyzed the medical records of 105 patients with and without diabetes and hypertension. Systolic BP (SBP), diastolic BP (DBP), and pulse pressure (PP) were examined. A multivariable linear regression model was used to analyze the correlation between eGFR and the VVV of BP. RESULTS No differences were demonstrated between the groups in the clinical characteristics. Mean SBP and DBP were not significant between the groups, and we observed no decrease in renal function. A significant negative correlation between PP and eGFR was observed in the total CKD population with a P of .010 (95% CI: -0.20, -0.03) and a correlation coefficient of -0.11. CONCLUSION Our study shows no statistical significances in terms of the VVVs of BP in any of the geriatric groups, with no significant decreases in renal function. However, we observed a significant negative correlation between PP and eGFR. We demonstrated that if a VVV of BP does not occur, there is no decrease in eGFR.

Abstract
INTRODUCTION A growing number of dominantly inherited Alzheimer's disease (DIAD) cases have become known in Latin American (LatAm) in recent years. However, questions regarding mutation distribution and frequency by country remain open. METHODS A literature review was completed aimed to provide estimates for DIAD pathogenic variants in the LatAm population. The search strategies were established using a combination of standardized terms for DIAD and LatAm. RESULTS Twenty-four DIAD pathogenic variants have been reported in LatAm countries. Our combined dataset included 3583 individuals at risk; countries with highest DIAD frequencies were Colombia (n = 1905), Puerto Rico (n = 672), and Mexico (n = 463), usually attributable to founder effects. We found relatively few reports with extensive documentation on biomarker profiles and disease progression. DISCUSSION Future DIAD studies will be required in LatAm, albeit with a more systematic approach to include fluid biomarker and imaging studies. Regional efforts are under way to extend the DIAD observational studies and clinical trials to Latin America.
