Objective-The aim of this study was to determine the prevalence and risk factors for microalbuminuria among south Indian type 2 diabetic patients attending a diabetes centre. Methods-One thousand four hundred and twenty five type 2 diabetic patients attending a diabetes centre in south India were recruited for the study. Urinary albumin concentration was measured by immunoturbodimetric assay. Microalbuminuria was diagnosed if the urinary albumin excretion was >30 mg/g of creatinine. Results-Overall prevalence of microalbuminuria was 36.3% (95% confidence interval 33.8 to 38.9). The prevalence of microalbuminuria increased with the increase in duration of diabetes. Multivariate regression analysis revealed age, diastolic blood pressure, glycated haemoglobin, fasting plasma glucose, and duration of diabetes to be associated with microalbuminuria. Conclusion-The overall prevalence of microalbuminuria in this south Indian clinic population and its risk factors are similar to that reported in Europeans. (Postgrad Med J 2001;77:399-402)

Objective Anecdotal evidence shows that the Shaker exercise and its modifications improve pharyngeal muscle contraction. However, there is no experimental evidence for the same. Thus, the present study examined the effect of modified Shaker exercise on the amplitude and duration of pharyngeal muscle contraction using cervical auscultation. Design The study follows a cross-sectional study design, where 50 healthy individuals (23 males and 27 females) performed modified Shaker exercise and noneffortful swallow during 10 ml water swallowing. Swallow sound characteristics were analyzed with and without modified Shaker exercise using cervical auscultation. Results The results of mixed ANOVA revealed significant differences for the amplitude of swallow sound with modified Shaker exercise (mean = 47.24, SD = 20.64) when compared to noneffortful swallow (mean = 28.19, SD = 10.26) at p < 0.05. However, no significant difference was obtained for the swallow sound duration with (mean = 0.19, SD = 0.07) and without (mean = 0.18, SD = 0.07) modified Shaker exercise at p > 0.05. No significant difference across the genders was also noted at p > 0.05. Conclusion The outcomes of the study suggest that modified Shaker exercise improves the amplitude of pharyngeal muscle contraction. Further studies are needed to confirm this finding using gold standard tools like videofluoroscopy.
