Using Automated HbA1c Testing to Detect Diabetes Mellitus in Orthopedic Inpatients and Its Effect on Outcomes.

Aims: The prevalence of diabetes is rising, and people with diabetes have higher rates of musculoskeletal-related comorbidities. HbA1c testing is a superior option for diabetes diagnosis in the inpatient setting. This study aimed to (i) demonstrate the feasibility of routine HbA1c testing to detect the presence of diabetes mellitus, (ii) to determine the prevalence of diabetes in orthopedic inpatients and (iii) to assess the association between diabetes and hospital outcomes and post-operative complications in orthopedic inpatients.

Elevated baseline glomerular filtration rate (GFR) is independently associated with a more rapid decline in renal function of patients with type 1 diabetes.

Aims: Renal hyperfiltration is observed prior to the development of diabetic kidney disease (DKD) in patients with type 1 diabetes (T1DM); however its significance remains uncertain. Longitudinal data were used to investigate the association between measured baseline glomerular filtration rate (GFR) and renal function decline in patients with T1DM.

Methods: This study included 142 adult patients with T1DM and ≥2 measurements of glomerular filtration rate (mGFR; determined by diethylene-triamine-penta-acetic acid plasma clearance).

The Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation does not improve the underestimation of Glomerular Filtration Rate (GFR) in people with diabetes and preserved renal function.

Background: Our hypothesis was that both the Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) equations would underestimate directly measured GFR (mGFR) to a similar extent in people with diabetes and preserved renal function.

Methods: In a cross-sectional study, bias (eGFR - mGFR) was compared for the CKD-EPI and MDRD equations, after stratification for mGFR levels. We also examined the ability of the CKD-EPI compared with the MDRD equation to correctly classify subjects to various CKD stages.

Estimating glomerular filtration rate in diabetes using serum cystatin C.

Chronic kidney disease (CKD) is a major public health problem, especially for people with diabetes. Not only is it a risk factor for end-stage renal disease (ESRD) but it is also a major cardiovascular disease (CVD) risk factor. Methods that accurately and simply estimate glomerular filtration rate (GFR) are therefore needed to optimise the detection and management of CKD in people with diabetes.

Integrating albuminuria and GFR in the assessment of diabetic nephropathy.

The evaluation of diabetic nephropathy from research and clinical viewpoints depends on the assessment of two continuous variables, albumin excretion rate (AER) and glomerular filtration rate (GFR). These two parameters form the basis of both the European classification of five stages of diabetic nephropathy, assessed according to changes in AER and GFR (hyperfiltration, normoalbuminuria, microalbuminuria, macroalbuminuria and end-stage renal disease), and the National Kidney Foundation classification of five stages of chronic kidney disease based on categories of estimated GFR. Although increases in AER generally precede a decline in GFR, some patients follow a non-albuminuric pathway to renal impairment.

Thyrotoxicosis during sunitinib treatment for renal cell carcinoma.

Context: Sunitinib malate is an oral tyrosine kinase inhibitor used in the treatment of renal cell carcinoma (RCC) and gastrointestinal stromal tumours. Hypothyroidism has been observed in patients treated with sunitinib, but the mechanism whereby sunitinib induces hypothyroidism is unknown.

Objective: To describe a series of six patients who developed thyrotoxicosis while on sunitinib for metastatic RCC.

Serial measurements of cystatin C are more accurate than creatinine-based methods in detecting declining renal function in type 1 diabetes.

Objective: Cystatin C-and creatinine-based methods were compared with (99m)-technetium-diethylene-triamine-penta-acetic acid ((99m)Tc-DTPA) plasma clearance (isotopic glomerular filtration rate [iGFR]) for detecting declining renal function.

Research Design And Methods: Glomerular filtration rate (GFR) was monitored over a mean of 10.1 years in 85 subjects with type 1 diabetes (with an average of 5.

Lowering of proteinuria in response to antihypertensive therapy predicts improved renal function in late but not in early diabetic nephropathy: a pooled analysis.

In late diabetic nephropathy (DN) the initial lowering of albumin excretion rate (AER) with antihypertensive therapy is proportional to the degree of subsequent preservation of glomerular filtration rate (GFR). Whether a similar relationship exists between AER and GFR in early diabetes is not known. The present analysis has compared AER and GFR responses to antihypertensive therapy in 33 published studies (77 treatment groups) of early and late DN in type 1 (T1) and type 2 (T2) diabetes, analyzed on an intention-to-treat basis.

The photon transport equation for turbid biological media with spatially varying isotropic refractive index.

Using the principle of energy conservation and laws of geometrical optics, we derive the photon transport equation for turbid biological media with spatially varying isotropic refractive index. We show that when the refractive index is constant, our result reduces to the standard radiative transfer equation and when the medium is lossless and free of scattering to the well known geometrical optics equations in refractive media.
