Association between Advanced Glycation End-Products, Carotenoids, and Severe Erectile Dysfunction. World J Mens Health 2023:41.e17.

Abstract
PURPOSE To investigate the association between skin advanced glycation end-products (AGEs) levels, blood antioxidative vitamin and carotenoid concentrations, and severe erectile dysfunction (ED) in community-dwelling men. MATERIALS AND METHODS This cross-sectional study used the 5-Item International Index of Erectile Function to identify 335 community-dwelling men with ED. The accumulation of skin AGEs was assessed noninvasively by measuring skin autofluorescence. Background-adjusted multivariable logistic regression analyses using the inverse probability of treatment weighting method were performed to evaluate the effects of AGEs, vitamins, and carotenoids on severe ED. Moreover, multiple linear regression analyses were performed to assess the association between skin AGEs levels and serum carotenoid concentrations. RESULTS The median age of study participants was 57 years. Of the 335 men, 289 (86.3%) and 46 (13.7%) were classified into the mild/moderate and severe ED groups, respectively. Multivariable analyses revealed that skin AGEs levels, blood vitamins C and E, lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene, total lycopene, and cis-lycopenes concentrations were significantly associated with severe ED, whereas all-trans lycopene concentrations were not. In the multiple linear regression analyses, serum zeaxanthin concentrations were negatively and significantly correlated with skin AGEs levels. CONCLUSIONS Higher skin AGEs levels and lower blood antioxidative vitamin and carotenoid concentrations were significantly associated with severe ED. Serum zeaxanthin levels were negatively and significantly correlated with skin AGEs levels, suggesting the possible effects of zeaxanthin on ED by decreasing tissue AGEs levels.

Abstract
INTRODUCTION The accumulation of tissue-advanced glycation end products in skin results from complex and consecutive reactions and can be measured by skin autofluorescence (SAF) reader devices. This overview discusses studies evaluating the utilization of SAF in screening renal and cardiac disease. MATERIALS AND METHODS Literature search was performed using Google Scholar, PubMed, Springer, Ovid, and ScienceDirect. RESULTS SAF was an independent predictor of progression of chronic kidney disease (CKD) and was elevated in subjects on hemodialysis and peritoneal dialysis. Furthermore, SAF was significantly associated with cardiovascular events, cardiovascular mortality, and all-cause mortality in CKD patients. Other studies revealed a correlation between SAF and arterial stiffness, vascular damage, and subclinical atherosclerosis. A vegetarian diet was associated with lower SAF levels, whereas malnutrition was correlated with higher levels and increased mortality. CONCLUSIONS SAF measurement may be useful in managing renal and cardiac disease. Future studies are needed to clarify the specific role of SAF in the management of CKD and its noninvasive office utilization to identify comorbidities in inflammatory diseases, such as psoriasis.

Abstract
The incidence and prevalence of diabetes are increasing worldwide, and cardiovascular disease (CVD) is the leading cause of death among subjects with type 2 diabetes (T2D). The assessment and stratification of cardiovascular risk in subjects with T2D is a challenge. Advanced glycation end products are heterogeneous molecules produced by non-enzymatic glycation of proteins, lipids, or nucleic acids. Accumulation of advanced glycation end products is increased in subjects with T2D and is considered to be one of the major pathogenic mechanism in developing complications in diabetes. Skin AGEs could be assessed by skin autofluorescence. This method has been validated and related to the presence of micro and macroangiopathy in individuals with type 2 diabetes. In this context, the aim of this review is to critically summarize current knowledge and scientific evidence on the relationship between skin AGEs and CVD in subjects with type 2 diabetes, with a brief reference to other diabetes-related complications.

Abstract
PURPOSE OF REVIEW Accurate risk stratification in patients with chronic kidney disease (CKD) is highly desirable to help guide earlier, targeted treatment in high-risk individuals. In this review, we report recent developments in our understanding of risk factors and risk prediction in patients with CKD. RECENT FINDINGS A large meta-analysis has shown that conventional cardiovascular risk factors continue to play an important role in disease progression and adverse outcomes in patients with advanced CKD where the estimated glomerular filtration rate (eGFR) is < 30 ml/min/1.73 m). Several studies have shed light on novel biomarkers in CKD, including peptides (LG1 M), genes (MUC1) and metabolic factors (urinary oxalate excretion). Cortical oxygenation measured by BOLD-MRI also provides a novel radiological measure predictive of future eGFR decline. A new risk prediction score for patients with CKD G4-5 has been developed, offering an aid to decision-making in these patients. SUMMARY Ongoing work across various disciplines continues to unravel the determinants of CKD progression. A few notable risk prediction tools in CKD have now surfaced but whether they can be utilised to offer improved care remains a key unanswered question.

Abstract
A novel chain-like coordination polymer [CuLCl2(DMF)]n (1) with helical double chains was synthesized using flexible bis(pyridylurea) ligand 1,1[Formula: see text]-[oxybis(2,1-phenylene)] bis(3-pyridin-3-ylurea) (L) under solvothermal conditions and characterized by single-crystal X-ray diffraction and elemental analysis. A green grinding processing method was used to produce the required complex 1 nanorods, which featured good water dispersibility. The protective effect of the compound was evaluated in vivo, following the construction of the coronary heart disease (CHD) rat model and nano 1 treatment. The cardiac function promoted by nano 1 was measured using the left ventricular systolic diameter (LVID) and left ventricular ejection fraction (LVEF). The anti-oxidative activity of nano 1 was determined with an ROS detection kit. In addition, the interaction between the Cu(II) complex with protein NF-[Formula: see text]B was examined by molecular docking.
