Introduction Early detection of diabetes mellitus (DM) and diabetic kidney disease (DKD) is important for preventing end-stage renal failure and reducing cardiovascular complications. Availability of a validated point-of-care (PoC) device that can measure various DKD markers would be useful in this respect, especially in resource-poor parts of the world. Methods We validated a novel nanotechnology-based multianalyte PoC device (minimally invasive and does not require trained medical personnel) against laboratory gold standard tests for the detection of 5 biomarkers related to management of DM and DKD. The prospective study was funded by an International Society of Nephrology American Nephrologists of Indian Origin grant in 2 phases: (i) proof of concept: random samples were tested for the analytes with the PoC device and correlated with the laboratory gold standard; and (ii) clinical validation in a well-characterized cohort of patients. A nonenzymatic- and nonantibody-based electrochemical PoC device for quantitative measurement of markers—glycosylated hemoglobin (HbA1c), hemoglobin, serum albumin, microalbuminuria, urine creatinine, and albumin-to-creatinine ratio−was developed and used in this study. The disposable strips were interfaced with a multipotentiostat hand-held PoC device (3.7-V rechargeable lithium battery, 5-inch touch screen, Bluetooth enabled) working in amperometry mode, which provided the results in

Leptospirosis is a recurring global disease of severe illness involving pulmonary and renal involvement in cattle and humans that needs attention to cure. The major challenge in treating leptospirosis disease is the diagnosis of the disease. The culturing of an organism is a gold standard for confirmation of the disease. The growth and optimistic identification of an organism require at least 8 to 14 days because of its slow growth characteristics. We have investigated various media conditions that are prepared based on the wealth of information obtained from 'omic' studies and report a sustainable Leptospira growth medium comprising of serum equivalent elements and nutrients for pyrimidine biosynthesis, which allows a visible growth of organism within 2 days.
