No difference in survival between the staggered tip and split-tip catheters was found.

With the advent of the "hub and spoke" model for dialysis in the public sector healthcare, TCCs are suboptimal with regards to patient and catheter survival, with high infection rates. It must be regarded as a temporary solution and AVF creation should be prioritized.

Patients with end-stage kidney disease (ESKD) suffer from functional iron deficiency where despite the presence of sufficient iron stores in the body, adequate iron is unavailable for heme synthesis. This study hypothesis was that in patients undergoing hemodialysis (HD), administration of intravenous (IV) ascorbic acid (AA) exerts a good effect on the management of anemia, either by increasing the mobilization of iron from tissue stores or acting as an antioxidant to overcome the inflammatory block and increase the erythropoietin sensitivity.

Fifty patients with ESRD who were on regular HD were included in the study. link2 Patients' ferritin levels ranged from 500 to 1200 ng/mL with transferrin saturation of 30% or more. However, all patients were anemic and received erythropoietin therapy. Iron therapy was discontinued in the first group, whereas it was continued in the second group that received IV AA.

A significant increase in the levels of Hb was observed in the second group after 6 months despite the decrease in ferritin levels in both the groups. Transferrin saturation decreased in both groups, the decrease being more in the first group. The levels of C-reactive protein (CRP) decreased in the second group, whereas these increased in the first group.

Intravenous AA as an adjuvant therapy with iron exerts a favorable and significant effect on the Hb, serum ferritin, and CRP levels in patients with ESKD having anemia. The discontinuation of iron therapy only decreases the serum ferritin levels and does not improve the Hb or CRP levels.

There is paucity of data on long-term outcome of lupus nephritis (LN) from south India. Our study looks at long term outcomes in patients with biopsy proven LN with terms of response to therapy, flare, mortality, treatment-related complications, outcome and post flare analysis. We also analyzed the factors which predicted the outcome.

A retrospective observational study was conducted from 2005 to 2012 at St. John's Medical college and hospital, Bangalore. Patients received treatment as per NIH protocol. Patients of LN who regularly visited OPD were included. Statistical analysis was done by using SPSS 19 software.

At end of 84 ± 6 months (
= 59), 38 subjects showed complete remission (CR), 6 partial remission (PR), 3 developed chronic kidney disease, 2 developed end-stage kidney disease (ESKD), and 10 died. In outcome of flare (
= 15), 7 had nephrotic flare, 3 had refractory flare, 3 showed nephritic flare with 2 developing ESKD. Change of LN class was 3 subjects had changed to class II from class IV, 1 to class II from class V, 7 to class III from class IV, 2 to class IV from class V, and 2 to class IV from class VI. Factors predicting poor outcomes were serum creatinine, hypertension at presentation, and failure to achieve remission in 1 year. 7 subjects conceived, of which 4 of them were treated with azathioprine (AZA) and 3 of them who were on mycophenolate mofetil and was changed to AZA. 4 subjects had successful pregnancy outcome, 2 had preeclampsia, and 1 subject had missed abortion.

At end of 84 ± 6 months, patient survival rate was 84%.

Methotrexate (MTX), used in the treatment of cancerous patients, causes toxicity in the different organs of the body. This study of rosmarinic acid (RA) is as an antioxidant on nephrotoxicity and hepatotoxicity induced by MTX.

Rats (n = 32) were divided into four groups sham; MTX; 100 mgkg RA + MTX; 200 mg/kg RA + MTX. The amount of MTX was 20 mg/kg. 24 hours after injection of the last dose of MTX, the blood samples and kidneys and liver of rats were studied. The aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), urea, serum creatinine were assessed. Tissue antioxidant enzymes and malondialdehyde (MDA) levels were measured. The liver and kidney tissues were histopathologically examined.

MTX significantly increased the urea, creatinine, ALT, AST, ALP levels, and renal MDA and significantly decreased renal catalase (CAT), hepatic glutathione (GSH), and hepatic CAT activity. MTX induced necrosis, leukocyte infiltration, eosinophilic casts, glomerular damage in kidney tissue and necrosis, degeneration and cellular vacuolization in liver tissues. RA at 100 mg/kg caused a significant decrease in ALT and AST and at two doses significantly decreased urea, renal MDA, and liver MDA. RA at 200 mg/kg significantly increased the renal CAT and liver GSH. RA in two doses significantly decreased necrosis and Leukocyte infiltration. RA caused a significant decrease in degeneration and cellular vacuolization in liver tissues.

RA with its antioxidant and anti-inflammatory characteristics decreased the MTX induced nephrotoxicity and hepatotoxicity.

The gamma gap (γ-gap) represents the total serum protein concentration minus the albumin concentration. The main aim of this study was to test whether the gamma gap is a predictor of mortality and whether it is associated with other predictors of mortality in chronic hemodialysis patients (CHPs).

We studied a cohort of 100 CHPs with a mean age of 59 ± 12.3 years with duration of dialysis 6.5 ± 4.7 years. link3 Serum proteins were determined by electrophoresis. The association of the gamma gap with serum C-reactive protein (CRP), fibrinogen and albumin concentration was evaluated for correlation. Cox regression analysis was used to identify the predictors of mortality.

The γ-gap correlates positively with CRP (r = 0.247,
= 0.013) and fibrinogen (r = 0.239,
= 0.016), and inversely with albumin (r = -0.430,
< 0.0001). The regression coefficients (b) and Exp (b) hazard ratio coefficients of covariates in Cox-regression survival analysis in all-cause outcomes were b = 0.1486, Exp (b) = 1.1602 (
< 0.0001); b = 0.0655, Exp (b) = 1.0677 (
< 0.0015) and b = -0.118, Exp (b) = 0.8887 (
< 0.0009), for γ-gap, CRP and albumin, respectively.

In patients on chronic hemodialysis, the gamma gap, along with serum albumin and CRP levels, is an independent predictor of mortality. Gamma gap levels correlate directly with serum CRP and fibrinogen levels and inversely with serum albumin levels.

Aims  The aim of our study was to compare the accuracy of HRUS and MRN for detecting various peripheral nerve pathologies, to choose the correct investigation to facilitate prompt patient management. Materials and Methods  This prospective study was done using HRUS with 14 MHz linear-transducer and 3 or 1.5T MR in cases referred for the assessment of peripheral nerve pathologies. Image interpretation was done using a scoring system (score 0-3 confidence level) to assess for nerve continuity/discontinuity, increased nerve signal/edema, fascicular change, caliber change, and neuroma/mass lesion. We determined the accuracy, sensitivity, and specificity of these modalities compared with the diagnostic standard determined by surgical and/or histopathological, if not performed then clinical and/or electrodiagnostic evaluation. Results  The overall accuracy of MRN was 89.3% (specificity 66.6%, sensitivity 92.6%, negative predictive value [NPV] 57.1%, positive predictive value [PPV] 95%) and that of HRUS was 82.9% (specificity 100%, sensitivity 80.4%, NPV 42.8, PPV 100). The confidence level for detecting nerve discontinuity and change in nerve caliber was found to be higher on ultrasonography than magnetic resonance imaging (MRI) (100 vs. 70% and 100 vs. 50%, respectively). Pathology of submillimeter caliber nerves was accurately detected by HRUS and these could not be well-visualized on MRI. Conclusion  HRUS is a powerful tool that may be used as the first-line imaging modality for the evaluation of peripheral nerve pathologies, and a better means of evaluation of peripheral nerves with submillimeter caliber.We describe topological dynamics over a space by starting from a simple ODE emerging out of two coupled variables. We describe the dynamics of the evolution of points in space within the deterministic and stochastic frameworks. Historically dynamical systems were associated with celestial mechanics. The core philosophies of two kinds of dynamics emerging from Poincaré and Lyapunov are described. Smale's contributions are highlighted. Markovian models are considered. Semi-group actions are a tool in this study.[This corrects the article DOI 10.1055/s-0041-1723909.].Coronavirus disease (COVID-19) caused by SARS-CoV-2 was notified from Wuhan city, Hubei province, China in the mid of December 2019. The disease is showing dynamic change in the pattern of confirmed cases and death toll in these low and middle-income countries (LMICs). In this study, exponential growth (EG) method was used to calculate the real-time reproductive number (Rt) for initial and later stage of epidemic in South Asian Association for Regional Cooperation (SAARC) member countries (April 2020 - December 2020). Time dependent (TD) method was used to calculate the weekly real -time reproduction number (Rt). We also presented the observations on COVID-19 epidemiology in relation with the health expenditure, poverty, BCG vaccination, literacy population density and Rt for understanding the current scenario, trends, and expected outcome of the disease in SAARC countries. A significant positive correlation was noticed between COVID-19 deaths and health expenditure (% GDP) (r = 0.58, P less then 0.05). The other factors such as population density/sq km, literacy %, adult population %, and poverty % were not significantly correlated with number of COVID-19 cases and deaths. Among SAARC countries, the highest Rt was observed in India (Rt = 2.10; 95% CI 2.04-2.17) followed by Bangladesh (Rt = 1.62; 95% CI 1.59-1.64) in initial state of epidemic. A continuous monitoring is necessitated in all countries looking at the medical facilities, available infrastructure and healthcare manpower, constraints which may appear with increased number of critically ill patients if the situation persists longer.
