RESUMEN

Background: Serum urea, creatinine, and estimated glomerular filtration rate (eGFR) are the most widely accepted parameters for the assessment of renal impairment. Renal dysfunction in Indian obese adults has not been sufficiently investigated. Aims: To evaluate the renal function by using serum urea, serum creatinine, eGFR, and proteinuria in normal, overweight, and obese adults to identify renal impairment. Materials and Methods: This observational and cross-sectional study was done on a total of 100 normoglycemic, normotensive healthy adults, and these were divided into three groups as per the criteria of body mass index (BMI) as; normal, overweight and obese groups. Estimation of urea and creatinine was done by fully automated chemistry analyzer methods. eGFR was calculated by Modified Diet Renal Disease (MDRD) formula. The excretion of protein in urine was checked by the urine dipsticks method. p<0.05 was considered as significant level. Results: The present study was conducted in 100 normal study subjects which included 48 males and 52 females. A maximum number of subjects were found in the obese subgroup (34%). Among subjects low eGFR prevalence was found 3% and prevalence of chronic kidney disease (CKD) was also found 3%. The obese subjects showed higher urea and creatinine levels compared to normal subjects. A significant negative relationship was noted in eGFR (MDRD) and BMI. The prevalence of proteinuria among subjects was 3%. Conclusions: A total of 3% prevalence of renal dysfunction was noted among adults and out of this 2% was found in obese adults. Therefore, it can be concluded that increasing BMI has a significant contributing factor for renal impairment in obese adults.

RESUMEN

Background: It is well established that chronic exposure to tobacco induces head and neck cancers but the exact etiopathogenesis is not known. Though studies have shown expression of TIMP1, EPS8 and AXL in cancers, their role in tobacco-induced cancers is not known. We aimed this study to evaluate the role of these molecules in oral and oropharyngeal squamous cell cancers (SCC). Materials and Methods: In this single institutional study, 31 patients of oral and oropharyngeal SCC with history of chewing tobacco were included. Smokers were excluded from the study. After informed consent biopsies were taken from affected and contralateral normal mucosa. Paraffin blocks were made and tissue microarray (TMA) were constructed using these blocks. Immunohistochemistry (IHC) for TIMP1, EPS8, AXL kinase was carried out on these tissue microarrays. The intensity of staining was scored from 0 to 3+, related to expression of each of the three molecules. Results: The expression of TIMP1, EPS8 and AXL kinase was significantly more in the cancerous mucosa versus non-cancerous mucosa (P = 0.000 in all three) in oral and oropharyngeal SCC exposed to chewing tobacco. Conclusion: Immunohistochemical expression of these molecular markers in oral and oropharyngeal SCC correlated with their molecular based studies. Significant IHC expression of TIMP1, EPS8 and AXL establishes their role in the pathogenesis of oral and oropharyngeal squamous cell carcinomas. Novel targeted therapies may be researched that can detect and target these molecules at an earlier stage of pathogenesis of these tumors.
