Frequency of proteinuria in type 2 diabetes mellitus seen at a diabetes centre in southern India

The frequency of proteinuria was assessed in a cohort of 1848 diabetic patients attending a diabetes centre in south India. A total of 127 (6.9%) patients had evidence of macroproteinuria and 49 (2.5%) patients had microproteinuria. Thus overall 9.4% of patients had diabetes related proteinuria. In addition, 70 patients (3.8%) had evidence of proteinuria with no evidence of retinopathy. The frequency of both microproteinuria and macroproteinuria increased linearly with duration of diabetes. Multiple logistic regression analysis showed that duration of diabetes, serum creatinine, and glycated haemoglobin were risk factors for macroproteinuria.     

An epidemiological study on patients undergoing dacryocystorhinostomy

Dacryocystorhinostomy is performed in patients with naso-lacrimal duct obstruction to bypass the site of obstruction so as to relieve the patient of the irritating and socially embarrassing symptoms of epiphora. We discuss the various epidemiological aspects especially the vast difference by which the females out-number the males in patients undergoing DCR and the likely explanations for this difference in our study on 74 patients which underwent DCR in our institute.     

Auditory brainstem implantation: The first Indian experience

Multichannel auditory brainstem implants (ABI) are currently indicated for patients with neurofibromatosis type II (NF2) involving both vestibulocochlear nerves. The ABI helps bypass the damaged cochlear nerves and restores a level of auditory sensation via the electrical stimulation of the cochlear nucleus. The implant is usually placed in the lateral recess of the fourth ventricle at the time of tumor resection to stimulate the cochlear nucleus. We report a case of ABI done on a 15-year-old girl with bilateral vestibular schwannomas.

In vitro hemocompatibility and vascular endothelial cell functionality on titania nanostructures under static and dynamic conditions for improved coronary stenting applications

The usefulness of nanoscale topography in improving vascular response in vitro was established previously on hydrothermally modified titanium surfaces. To propose this strategy of surface modification for translation onto clinically used metallic stents, it is imperative that the surface should be also hemocompatible: an essential attribute for any blood-contacting device. The present in vitro study focuses on a detailed hemocompatibility evaluation of titania nanostructures created through an alkaline hydrothermal route on metallic Ti stent prototypes. Direct interactions of TiO₂ nanocues of various morphologies with whole blood were studied under static conditions as well as using an in vitro circulation model mimicking arterial flow, with respect to a polished Ti control. Nanomodified stent surfaces upon contact with human blood showed negligible hemolysis under constant shear and static conditions. Coagulation profile testing indicated that surface roughness of nanomodified stents induced no alterations in the normal clotting times, with insignificant thrombus formation and minimal inflammatory reaction. Endothelialized nanomodified Ti surfaces were found to inhibit both activation as well as aggregation of platelets compared with the control surface, with the endothelium formed on the nanosurfaces having an increased expression of anti-thrombogenic genes. Such a nanotextured Ti surface, which is anti-thrombogenic and promotes endothelialization, would be a cost-effective alternative to drug-eluting stents or polymer-coated stents for overcoming in-stent restenosis.     

Am I Ready to Be an Independent Neuroradiologist? Objective Trends in Neuroradiology Fellows' Performance during the Fellowship Year

BACKGROUND AND PURPOSE:Aside from basic Accreditation Council for Graduate Medical Education guidelines, few metrics are in place to monitor fellows'' progress. The purpose of this study was to determine objective trends in neuroradiology fellowship training on-call performance during an academic year.MATERIALS AND METHODS:We retrospectively reviewed the number of cross-sectional neuroimaging studies dictated with complete reports by neuroradiology fellows during independent call. Monthly trends in total call cases, report turnaround times, relationships between volume and report turnaround times, and words addended to preliminary reports by attending neuroradiologists were evaluated with regression models. Monthly variation in frequencies of call-discrepancy macros were assessed via χ² tests. Changes in frequencies of specific macro use between fellowship semesters were assessed via serial 2-sample tests of proportions.RESULTS:From 2012 to 2017, for 29 fellows, monthly median report turnaround times significantly decreased during the academic year: July (first month) = 79 minutes (95% CI, 71–86 minutes) and June (12th month) = 55 minutes (95% CI, 52–60 minutes; P value = .023). Monthly report turnaround times were inversely correlated with total volumes for CT (r = –0.70, F = 9.639, P value = .011) but not MR imaging. Words addended to preliminary reports, a surrogate measurement of report clarity, slightly improved and discrepancy rates decreased during the last 6 months of fellowship. A nadir for report turnaround times, discrepancy errors, and words addended to reports was seen in December and January.CONCLUSIONS:Progress through fellowship correlates with a decline in report turnaround times and discrepancy rates for cross-sectional neuroimaging call studies and slight improvement in indirect quantitative measurement of report clarity. These metrics can be tracked throughout the academic year, and the midyear would be a logical time point for programs to assess objective progress of fellows and address any deficiencies.

A fellow''s progress in an academic year is primarily assessed using qualitative, thus subjective, criteria, including achievement of Accreditation Council for Graduate Medical Education–prescribed milestones and faculty evaluations. While the Accreditation Council for Graduate Medical Education provides requirements for total yearly cases read¹ and individual programs may have internal metrics for fellows'' progress, there are no concrete external objective measurements for documenting fellows'' progress within the academic year. Often, fellows are unsure whether their efficiency in generating reports, report turnaround times (RTATs) for on-call examinations, or quality of on-call reports is satisfactory.The total number of studies dictated by the fellow and the RTATs of on-call studies may be reviewed by the attendings and program director with the fellows, but more meaningful interpretation of these numbers is lacking because there are no comparison benchmarks or quantitative checkpoints within the fellowship year. Knowledge of these factors is critical in a fellowship program so that program directors and fellows are jointly aware of progress throughout the year and remediation or additional focused training can be implemented, as necessary. More data on neuroradiology fellowship training are especially needed because a survey in 2016 demonstrated that 25% of practicing neuroradiologists in the United States believe that fellows'' abilities have declined.² Prior studies have analyzed various other factors related to radiology residency training, including total cases read, turnaround time, and on-call accuracy,^3,4 but to our knowledge, no studies have analyzed the quantitative trends in fellowship training during an academic year.We hypothesized that within an academic year, the RTAT for on-call studies dictated by fellows will decrease (ie, improve). Meanwhile, the discrepancy rates will decrease, and clarity of reports will improve. We also hypothesized that participating in independent call will have residual short-term effects on increasing clinical productivity during a subsequent regular work week.
