A new gender-specific model for skin autofluorescence risk stratification

Advanced glycation endproducts (AGEs) are believed to play a significant role in the pathophysiology of a variety of diseases including diabetes and cardiovascular diseases. Non-invasive skin autofluorescence (SAF) measurement serves as a proxy for tissue accumulation of AGEs. We assessed reference SAF and skin reflectance (SR) values in a Saudi population (n = 1,999) and evaluated the existing risk stratification scale. The mean SAF of the study cohort was 2.06 (SD = 0.57) arbitrary units (AU), which is considerably higher than the values reported for other populations. We show a previously unreported and significant difference in SAF values between men and women, with median (range) values of 1.77 AU (0.79–4.84 AU) and 2.20 AU (0.75–4.59 AU) respectively (p-value « 0.01). Age, presence of diabetes and BMI were the most influential variables in determining SAF values in men, whilst in female participants, SR was also highly correlated with SAF. Diabetes, hypertension and obesity all showed strong association with SAF, particularly when gender differences were taken into account. We propose an adjusted, gender-specific disease risk stratification scheme for Middle Eastern populations. SAF is a potentially valuable clinical screening tool for cardiovascular risk assessment but risk scores should take gender and ethnicity into consideration for accurate diagnosis

Obesity and morbid obesity associated with higher odds of hypoalbuminemia in adults without liver disease or renal failure

Rana H Mosli,1 Hala H Mosli2 1Clinical Nutrition Department, Faculty of Applied Medical Sciences, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia; 2Division of Endocrinology and Metabolism, Department of Medicine, Faculty of Medicine, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia Background and objective: Studies are needed in order to inform recommendations for interpreting albumin levels among obese individuals without known medical conditions associated with hypoalbuminemia. The objective of this study was to examine the association of obese and morbidly obese status with hypoalbuminemia, while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome.Patients and methods: Retrospective data collection from adult patients presenting to the outpatient Endocrinology and Metabolism Clinic was performed between January 2015 and December 2015. An initial sample of 180 patients was selected. After excluding patients who were younger than 18 years, who had known cases of liver disease or renal failure, or who had missing data, a final sample of 122 subjects was identified. Serum albumin and objectively measured weight and height data were retrieved from hospital records. A board-certified endocrinologist reviewed patient records to identify the presence of renal and diabetic conditions. Descriptive statistics were used to examine sample characteristics. Multiple logistic regression analysis was used to examine the association of obesity and morbid obesity with hypoalbuminemia (serum albumin < 34 g/L) while adjusting for age, sex, diabetes, prediabetes, diabetic nephropathy, and nephrotic syndrome.Results: Approximately 43% of the sample were categorized as obese and 13% were categorized as morbidly obese. The mean serum albumin level was 38.00 g/L (standard deviation [SD] = 4.26) among subjects who were neither overweight nor obese, 38.35 g/L (SD = 0.48) among overweight subjects, 34.57 g/L (SD = 4.71) among obese subjects, and 33.81 g/L (SD = 3.71) among morbidly obese subjects. Adjusting for age, sex, diabetes, prediabetes, nephrotic syndrome, and diabetic nephropathy, obese subjects had significantly higher odds of hypoalbuminemia (odds ratio [OR]: 4.10, 95% confidence interval [CI]: 1.50–11.27, P-value = 0.006), as did morbidly obese subjects (OR: 6.94, 95% CI: 1.91–25.23, P-value = 0.003).Conclusion: The findings suggest that obesity and morbid obesity can be considered as independent predictors of hypoalbuminemia. The findings can be used to inform future studies aiming to better understand the association of obesity and morbid obesity with hypoalbuminemia and to help inform guidelines for clinicians on how to correctly interpret and utilize serum albumin data for obese individuals.

The effect of obesity and components of metabolic syndrome on urinary and sexual functions in Saudi men

Hisham A Mosli,1 Hala H Mosli,2 Akram A Bokhari1 1Department of Urology, 2Department of Internal Medicine (Endocrinology), King Abdulaziz University Hospital, Jeddah, Saudi Arabia Objective: To establish a possible association between obesity, measured by waist circumference (WC) and body mass index (BMI), and voiding and sexual functions in a random cohort of Saudi men. Materials and methods: An outpatient men’s health clinic was set up at King Abdulaziz University Hospital in Jeddah, Saudi Arabia and men were invited to discuss their sexual and urinary functions. The data collected included age, WC, weight, height, blood pressure, history of diabetes, hypertension, and smoking. The International Prostate Symptom Score (IPSS) and the International Inventory of Erectile Function (IIEF-5) questionnaire were used to assess urinary tract symptoms and sexual function, respectively. Serum testosterone, prostate-specific antigen and cholesterol levels were measured and documented. Data were analyzed using the Statistical Package for the Social Sciences. Results: We recruited 113 participants. The mean WC and BMI of the men were 104 ± 14.599 cm and 29.706 kg/m2, respectively. Thirty-seven men (32.7%) had an IPSS ≥ 8 points. Sexual disorders were reported in 19 men; 16 men had erectile dysfunction, while three had premature ejaculation. Of the whole cohort, 37 men were diabetic, of which 15 (40.5%) had an IPSS ≥ 8 and 13 (35%) were either overweight or obese. Conclusion: Increased WC and BMI were associated with diabetes mellitus and large percentages of voiding and sexual disorders.
