Published: February 2010

Background and Objective

The downward directed exit of the swan neck catheter may decrease the risk of exit-site infection (ESI). The percentage of migrations of the swan neck catheter seems to be less than the conventional Tenckhoff catheter and the swan neck catheter is more expensive and cannot be manipulated by guidewire technique if tip migration occurs. In this study, the conventional Tenckhoff catheter was used. The straight tunnel was converted to an arcuate one using the triple incision method, resulting in a downward directed exit. The arcuate tunnel was created by passing the catheter through an additional incision located between the paramedian incision and the exit site. We compared the infective and mechanical complications of the Tenckhoff catheter with a downward exit, implanted using the triple incision method, with the swan neck catheter.

Patients and Methods

101 new peritoneal dialysis patients were prospectively randomized to receive either the Tenckhoff catheter with a downward exit, implanted using the triple incision method, or the swan neck catheter. Each patient was followed up for 24 months. 50 patients were in the triple incision method group (TIMG) and 51 were in the swan neck catheter group (SNCG).

Results

Over a mean period of 18.9 ± 8.0 months of follow-up, ESI occurred in 35 patients (70%) in TIMG and 37 patients (72.5%) in SNCG ( p = 0.83). The ESI rates were 0.71 and 1.0 episodes/catheter-year in TIMG and SNCG respectively ( p = 0.21). The peritonitis rates were similar in the 2 groups (0.64 episodes/year in TIMG and 0.68 episodes/year in SNCG, p = 0.47). More patients in TIMG had tip migration [15 patients (30%) in TIMG vs 10 patients (19.6%) in SNCG] but the difference was not statistically significant. Repositioning of the catheter by guidewire manipulation was successful in patients in TIMG but not in SNCG. Overall catheter survival at 12 and 24 months was 95% and 83% in TIMG and 93% and 79% in SNCG respectively ( p = 0.72).

Conclusion

By using the conventional Tenckhoff catheter with a downward exit created using the triple incision method, high catheter survival rates with infective and mechanical complication rates similar to those of the swan neck catheter can be achieved. The triple incision method has the additional advantages of lower cost and the catheter can be manipulated by guidewire technique if tip migration occurs.

Background

Relative to hemoglobin A1c (HbA1c), percentage of glycated albumin (GA%) more accurately reflects recent glycemic control in diabetic hemodialysis (HD) patients.

Methods

To determine the accuracy of glycemic assays in a larger sample including patients on peritoneal dialysis (PD), HbA1c and GA% were measured in 519 diabetic subjects: 55 on PD, 415 on HD, and 49 non-nephropathy controls.

Results

Mean ± SD serum glucose levels were higher in HD and PD patients relative to non-nephropathy controls (HD 169.7 ± 62 mg/dL, PD 168.6 ± 66 mg/dL, controls 146.1 ± 66 mg/dL; p = 0.03 HD vs controls, p = 0.13 PD vs controls). GA% was also higher in HD and PD patients (HD 20.6% ± 8.0%, PD 19.0% ± 5.7%, controls 15.7% ± 7.7%; p < 0.02 HD vs controls and PD vs controls). HbA1c was paradoxically lower in dialysis patients (HD 6.78% ± 1.6%, PD 6.87% ± 1.4%, controls 7.3% ± 1.4%; p = 0.03 HD vs controls, p = 0.12 PD vs controls). The serum glucose/HbA1c ratio differed significantly between dialysis patients and controls ( p < 0.0001 HD vs controls, p = 0.002 PD vs controls), while serum glucose/GA% ratio was similar across groups ( p = 0.96 HD vs controls, p = 0.64 PD vs controls). In best-fit multivariate models with HbA1c or GA% as outcome variable, dialysis status was a significant predictor of HbA1c but not GA%.

Conclusions

The relationship between HbA1c and GA% differs in diabetic patients with end-stage renal disease who perform either PD or HD compared to those without nephropathy. HbA1c significantly underestimates glycemic control in peritoneal and hemodialysis patients relative to GA%.
Arterial Pulse Wave Velocity and Peritoneal Transport Characteristics Independently Predict Hospitalization in Chinese Peritoneal Dialysis Patients

Published: February 2010

Objective

Cardiovascular disease (CVD) is the most common cause of mortality in chronic peritoneal dialysis (PD) patients. Increased arterial stiffness may be related to a high peritoneal permeability resulting in fluid overload in PD patients. We studied the relations between arterial stiffness, peritoneal transport, and radiographic parameters of systemic fluid overload in a cohort of Chinese PD patients.

Design

Prospective cohort study.

Setting

University referral center.

Patients

We studied 107 PD patients. Vascular pedicle width and cardiothoracic ratio were measured from a plain postero-anterior chest radiograph. Pulse wave velocity (PWV) was determined at carotid–femoral (C-F) and carotid–radial sites. Peritoneal transport was determined by the dialysate-to-plasma ratio (D/P) of creatinine at 4 hours of dwell. Patients were followed for 9.4 ± 4.6 months.

Outcome Measures

Duration of hospitalization; actuarial and technique survival.

Results

There were no relationships between radiographic measures, arterial PWV, and D/P creatinine. However, both C-F PWV and D/P creatinine were independent predictors of the number of hospitalizations for CVD. None of the parameters correlated with mortality in this study.

Conclusions

There were no relationships between radiological parameters of fluid overload, peritoneal transport characteristics, and arterial PWV. Both C-F PWV and D/P creatinine were independent predictors of the number of hospitalizations for CVD. Our result suggests that arterial stiffness and high peritoneal transport each contribute to the development of CVD in this group of patients.
Successful Peritoneal Dialysis in a Hemophilia a Patient with Factor VIII Inhibitor
Authors: Solak Y. , Turkmen K. , Atalay H. , Turk S.
Published: February 2010

Chronic kidney disease and need for renal replacement therapy in hemophiliacs are relatively rare occurrences. Successful hemodialysis and peritoneal dialysis applications have been reported in the literature. We report a difficult-to-manage patient with hemophilia A plus factor VIII inhibitor who presented with gastrointestinal bleeding complicated by uremia. We admitted this hemophilia A patient with gastrointestinal bleeding who did not take regular factor infusions. He also had chronic kidney disease due to urinary stone disease. Since uremia might have contributed to bleeding, we chose hemodialysis along with factor VIII supplementation. His factor VIII and factor VIII inhibitor levels were 4% and 5 Bethesda units respectively. In order to bypass the inhibitor, we applied factor VIIA and prothrombin complex concentrate. After cessation of the hemorrhage, we placed a Tenckhoff catheter under prothrombin complex concentrate infusion. We did not observe any perioperative complication. To our knowledge, this is the first report of successful peritoneal dialysis in a hemophilia A patient who had factor VIII inhibitors.

Objective

The peritoneal equilibration test (PET) using 3.86% glucose solution is preceded by a long dwell with 3.86% glucose solution. A point of concern in patients treated with automated peritoneal dialysis (APD) is the influence of the preceding short nightly dwells on the results of a standardized PET. The aim of the study was to compare net ultrafiltration, small solute transport, sodium sieving, and solute transport type between a PET preceded by a long night dwell and one preceded by short (APD) dwells.

Patients and Methods

13 stable APD patients (mean age 60 ± 15 years; mean duration of peritoneal dialysis 31 ± 15 months) underwent 2 PETs: 1 preceded by short nightly dwells (PET A) and 1 preceded by a long night dwell (PET B).

Results

Both PETs were performed within a mean period of 8 (range 5 – 11) days. Mean total ultrafiltration of PET A was 626 ± 218 mL and PET B was 644 ± 223 mL (NS). The 4-hour results of both tests for dialysate-to-plasma (D/P) ratios of creatinine and urea, Dt/D0 ratios of glucose, and the dip in D/P sodium (sodium sieving) were similar. Classification of transport categories was identical for 10 of 13 patients.

Conclusion

In APD, the preceding dwell time of a 3.86% glucose PET does not influence fluid transport, solute transport, or transport type.
Construction of 2D isomorphism for 2D H∞‐control of Sturm‐Liouville systems
Authors: Hong Boe‐Shong
Published: February 2010

This work makes possible that H∞‐loopshaping has a 2D version for the Sturm‐Liouville class of distributed parameter systems. Here, the Laplace integral is composite of a Galerkin projection to transform the underlying dynamics, both spatially distributed and temporally varying, into pure algebra, so that any technique of classical control becomes applicable to spatio‐temporal analyses and syntheses. Accompanied by this Laplace‐Galerkin transform and its inverse are Fourier‐Galerkin transforms that constitute a pair of geometrical isomorphism between space‐time domain and mode‐frequency domain. Based on the isomorphism, Small Gain Theorem and H∞‐loopshaping can expand on 2D version in terms of mode‐frequency responses.

Treatment of Arsenic Contaminated Groundwater Using Calcium Impregnated Granular Activated Carbon in a Batch Reactor: Optimization of Process Parameters
Authors: Mondal Prasenjit , Mohanty Bikash , Balomajumder Chandrajit
Published: February 2010

This paper is an experimental investigation into the removal of arsenic species from simulated groundwater by adsorption onto Ca2+ impregnated granular activated carbon (GAC‐Ca) in the presence of impurities like Fe and Mn. The effects of adsorbent concentration, pH and temperature on the percentage removal of total arsenic (As(T)), As(III) and As(V) have been discussed. Under the experimental conditions, the optimum adsorbent concentration of GAC‐Ca was found to be 8 g/L with an agitation time of 24 h, which reduced As(T) concentration from 188 to 10 μg/L. Maximum removal of As(V) and As(III) was observed in a pH range of 7–11 and 9–11, respectively. Removal of all the above arsenic species decreased slightly with increasing temperature. The presence of Fe and Mn increased the adsorption of arsenic species. Under the experimental conditions at 30°C, the maximum percentage removals of As(T), As(III), As(V), Fe, and Mn were found to be ca. 94.3, 90.6, 98.0, 100 and 63%, respectively. It was also observed that amongst the various regenerating liquids used, a 5 N H2SO4 solution exhibited maximum regeneration (ca. 91%) of the spent GAC‐Ca.
Epigenetic influence of social experiences across the lifespan
Authors: Champagne Frances A.
Published: February 2010

The critical role of social interactions in driving phenotypic variation has long been inferred from the association between early social deprivation and adverse neurodevelopmental outcomes. Recent evidence has implicated molecular pathways involved in the regulation of gene expression as one possible route through which these long‐term outcomes are achieved. These epigenetic effects, though not exclusive to social experiences, may be a mechanism through which the quality of the social environment becomes embedded at a biological level. Moreover, there is increasing evidence for the transgenerational impact of these early experiences mediated through changes in social and reproductive behavior exhibited in adulthood. In this review, recent studies which highlight the epigenetic effects of parent–offspring, peer and adult social interactions both with and across generations will be discussed and the implications of this research for understanding the developmental origins of individual differences in brain and behavior will be explored. © 2010 Wiley Periodicals, Inc.

Published: February 2010

Thioglycolic acid (TGA) is a popular coating material for the preparation of aqueous quantum dots (QDs), yet dihydrolipoic acid (DHLA) has not been studied much. Here we present a detailed study on the aqueous synthesis of CdTe/CdS quantum dots with a DHLA coating. The outer CdS shell and DHLA stabilizer provide efficient confinement of electron and hole wave functions inside the nanocrystal as well as high photochemical stability. At the optimum ratios and reaction conditions, the results indicate that the DHLA‐capped CdTe/CdS QDs exhibit high fluorescence quantum yields (QYs) of about 48 % over a spectral range of 551–571 nm, and the best QY is 87 %. These DHLA‐capped core–shell QDs are highly biocompatible and monodisperse. In particular, they have exhibited excellent colloidal and photostability over one year of study. The synthesis of QDs by using DHLA as stabilizer is simple and environmentally friendly, and it can easily be extended to the large‐scale, aqueous‐phase production of QDs. At a QD dose of 120 μg/mL, TGA‐stabilized CdTe QDs induce 9.5 % hemolysis, whereas DHLA‐stabilized CdTe/CdS QDs induce only 3 % hemolysis. Hemolytic results indicate that DHLA‐stabilized QDs are more biocompatible than TGA‐capped CdTe QDs, which is especially important for QDs as biomarkers in biological detection and diagnosis.

Published: February 2010

This work studies the effect of a previous hydrostatic high‐pressure (HHP) treatment on chilled farmed coho salmon (Oncorhynchus kisutch). Three different HHP conditions were applied (135 MPa‐30 s, 170 MPa‐30 s, and 200 MPa‐30 s for treatments T‐1, T‐2, and T‐3, respectively) and compared to untreated (control) fish throughout a 20‐day chilled storage. Microbial activity and lipid oxidation development were analyzed. Assessment of aerobe, psychrotroph, Shewanella spp. and Pseudomonas spp. counts and trimethylamine formation showed a marked inhibitory effect (p <0.05) of HHP treatment on microbial activity, with this effect increasing with the pressure value employed. Related to lipid oxidation development, higher peroxide mean values (day 10–20 period) were found in control samples and fish treated under T‐1 condition when compared to their counterparts corresponding to T‐2 and T‐3 treatments. On the contrary, quantification of thiobarbituric acid‐reactive substances and fluorescent interaction compounds showed higher levels (p <0.05) in fish samples corresponding to T‐2 and T‐3 treatments. In spite of the lipid oxidation development found, polyene index and tocopherol isomer (α and γ) content did not provide differences (p >0.05) as a result of previous HHP treatment.
A Synthon for the Convenient and Efficient Introduction of Tetrazolylmethyl Groups into Nucleophile‐Bearing Compounds

Published: February 2010

An activated synthon for the efficient introduction of a protected tetrazolylmethyl group into nucleophile‐bearing compounds is presented. The β‐cyanoethyl protecting group allows for very effective deprotection under mild basic conditions. The synthon can be prepared by a two‐step procedure (42 %) starting from cheap starting material and can alkylate piperidine in 91 % yield. Even quadruple alkylation to form a protected version of the hexadentate ligand EDTT gives decent yields. Simultaneous removal of the four protecting groups furnishes the lithium salt of a formally zwitterionic ligand in 75 % yield. Finally, the synthon's performance has been assessed by comparison with its benzyl‐protected counterpart and was found to be equally efficient in the alkylation of simple amines but superior in deprotection. For substrates bearing basic amine sites, the β‐cyanoethyl group is largely preferable.

Metalloproteases (ADAMs, MMPs) are multidomain proteins that play key roles in extracellular matrix remodelling and degradation, in cell–cell and cell–matrix interactions and in the proteolytic liberation of membrane‐anchored proforms of cytokines and growth factors, the so‐called ectodomainshedding. In this work we describe the development ofphotoactivatable activity‐based probes with which active metalloproteases can be visualised. Our probes are based on the succinyl hydroxamate motif and differ in the positioning of the trifluoromethylphenyldiazirine photoreactive group. We demonstrate that directing the photoactivatable group towards the S1′ pocket yields activity‐based probes more effective than the corresponding probe with the photoactivatable group directed towards the S2′ pocket.
The SNM1/Pso2 family of ICL repair nucleases: From yeast to man
Authors: Cattell Emma , Sengerová Blanka , McHugh Peter J.
Published: February 2010

Efficient interstrand crosslink (ICL) repair in yeast depends on the Pso2/Snm1 protein. Pso2 is a member of the highly conserved metallo‐β‐lactamase structural family of nucleases. Mammalian cells possess three SNM1/Pso2 related proteins, SNM1A, SNM1B/Apollo, and SNM1C/Artemis. Evidence that SNM1A and SNM1B contribute to ICL repair is mounting, whereas Artemis appears to primarily contribute to non‐ICL repair pathways, particularly some double‐strand break repair events. Yeast Pso2 and all three mammalian SNM1‐family proteins have been shown to possess nuclease activity. Here, we review the biochemical, genetic, and cellular evidence for the SNM1 family as DNA repair factors, focusing on ICL repair. Environ. Mol. Mutagen. 2010. © 2010 Wiley‐Liss, Inc.
Integrated assessment of oil pollution using biological monitoring and chemical fingerprinting

Published: February 2010

A full assessment of the impact of oil and chemical spills at sea requires the identification of both the polluting chemicals and the biological effects they cause. Here, a combination of chemical fingerprinting of surface oils, tissue residue analysis, and biological effects measures was used to explore the relationship between spilled oil and biological impact following the grounding of the MSC Napoli container ship in Lyme Bay, England in January 2007. Initially, oil contamination remained restricted to a surface slick in the vicinity of the wreck, and there was no chemical evidence to link biological impairment of animals (the common limpet, Patella vulgata) on the shore adjacent to the oil spill. Secondary oil contamination associated with salvage activities in July 2007 was also assessed. Chemical analyses of aliphatic hydrocarbons and terpanes in shell swabs taken from limpet shells provided an unequivocal match with the fuel oil carried by the ship. Corresponding chemical analysis of limpet tissues revealed increased concentrations of polycyclic aromatic hydrocarbons (PAHs) dominated by phenanthrene and C1 to C3 phenanthrenes with smaller contributions from heavier molecular weight PAHs. Concurrent ecotoxicological tests indicated impairment of cellular viability (p < 0.001), reduced immune function (p < 0.001), and damage to DNA (Comet assay, p < 0.001) in these animals, whereas antioxidant defenses were elevated relative to un-oiled animals. These results illustrate the value of combining biological monitoring with chemical fingerprinting for the rapid identification of spilled oils and their sublethal impacts on biota in situ. Environ.
