Abstract : Comparative Efficacy of Serum Creatinine and Microalbuminuria in Detecting Early Renal Injury in Asphyxiated Babies in Calabar, Nigeria
|
|
Abstract: Background: Microalbuminuria and serum creatinine are markers of acute kidney injury. Birth asphyxia is responsible for 50% of all newborn deaths and acute non-oliguric kidney injury is one of such complications. This study was undertaken to determine the efficacy of serum creatinine and microalbuminuria for the detection of early renal lesion in severely asphyxiated babies in Calabar, Nigeria. Materials and Method: This prospective cross-sectional investigational study was undertaken among severely asphyxiated babies admitted into the newborn units of the University of Calabar Teaching Hospital (UCTH), Calabar, Nigeria. Standard method for blood collection and determination of urea, electrolytes were used. Micral-test strips were used on samples negative only for albumin after using urine dipstick. Color comparison was done with the standardized color scale on test strip container after 5 minutes. Results: Fifty term newborn babies were enrolled, their serum electrolytes, creatinine and creatinine clearance were essentially normal. Six (12%) babies had positive microalbuminuria, while 44(88%) had negative microalbuminuria with specificity and negative predictive values of 100% and 88% respectively. Conclusion: Microalbuminuria was not useful for early detection of acute renal failure in babies with severe birth asphyxia, but further studies are recommended.

Abstract : Comparing Two Waist-to-Height Ratio Measurements with Cardiometabolic Risk Factors among Youth with Diabetes
|
|
Abstract: Background: Waist circumference (WC) is commonly measured by either the World Health Organization (WHO) or National Health and Nutrition Examination Survey (NHANES) protocol. Objective: Compare the associations of WHO vs. NHANES WC-to-height ratio (WHtR) protocols with cardiometabolic risk factors (CMRFs) in a sample of youth with diabetes. Methods: For youth (10–19 years old with type 1 [N=3082] or type 2 [N=533] diabetes) in the SEARCH for Diabetes in Youth Study, measurements were obtained of WC (by two protocols), weight, height, fasting lipids (total cholesterol, triglycerides, HDL cholesterol, Non-HDL cholesterol) and blood pressures. Associations of CMRFs with WHO and NHANES WHtR were modeled stratified by body mass index (BMI) percentiles for age/sex: lower BMI (<85th BMI percentile; N=2071) vs. higher BMI (≥85th percentile; N=1594). Results: Among lower-BMI participants, both NHANES and WHO WHtR were associated (p<0.005) with all CMRFs except blood pressure. Among higher-BMI participants, both NHANES and WHO WHtR were associated (p<0.05) with all CMRFs. WHO WHtR was more strongly associated (p<0.05) than NHANES WHtR with triglycerides, non-HDL cholesterol, and systolic blood pressure in lower-BMI participants. Among high-BMI participants, WHO WHtR was more strongly associated (p<0.05) than NHANES WHtR with triglycerides and systolic blood pressure. Conclusion: Among youth with diabetes, WHtR calculated from either WC protocol captures cardiometabolic risk. The WHO WC protocol may be preferable to NHANES WC.

Abstract : BMI, Body Image, Emotional Well-Being and Weight-Control Behaviors in Urban African American Adolescents
|

Abstract: Importance: While urban African American adolescents face significant health disparities associated with overweight and obesity that follow them into adulthood; there is limited data on body image, emotional well-being, and weight control behaviors in this population to design effective public health interventions. Objective: This study was designed to understand the association of weight status to adolescent weight control, body image, and emotional well-being responses, in African American high school students. Design/Setting/Participants: The study cohort consisted of 776 students, mean age 15.8 years (±1.2). Data from Guidelines for Adolescent Preventive Services (GAPS) student surveys and anthropometric studies were collected at School-Based Health Centers. Main Outcome Measures: Associations between adolescent responses on the GAPS and body mass index (BMI) status (healthy weight: 5th to less than 85th percentile, overweight: 85th to less than 95th percentile, obese: 95th percentile or greater) were estimated using logistic regression and dose- response plots. Results: There were statistically significant associations between BMI category and weight control (ranging from a mean 5.18 to 7.68 odds of obesity) and body image (3.40 to 13.26 odds of obesity) responses. Responses to weight control and body image questions exhibited a dose- response for odds of overweight and obesity. Feelings of depressed mood were associated with obesity (1.47 times the odds of obesity compared to students who did not endorse depressed mood; 95% CI, 1.01 to 2.13) but not overweight status. Conclusion and Relevance: Overweight and obese urban African American adolescents are more likely to screen positively on weight control risk behaviors and negative body image questions than their normal weight peers. The weight control and body image measures on the GAPS may provide information to identify youth in need of services and those motivated for brief school-based weight control interventions.
