Peritoneal Dialysis Catheter Placement: Percutaneous and Peritoneoscopic Techniques
Authors: El Khudari Husameddin , Abdel-Aal Ahmed Kamel , Abaza Masa , Almehmi Sloan E. , Sachdeva Bharat , Almehmi Ammar 
Published: February 2022

AbstractChronic peritoneal dialysis (PD) is an underutilized renal replacement therapy in treating end-stage renal disease that has several advantages over hemodialysis. The success of continuous ambulatory PD is largely dependent on a functional long-term access to the peritoneal cavity. Several methods have been developed to place the PD catheter using both surgical and percutaneous techniques. The purpose of this article is to describe the percutaneous techniques using fluoroscopy guidance and peritoneoscope method. While fluoroscopic method uses fluoroscopy guidance and a guidewire to place the PD catheter, the peritoneoscopic technique utilizes a needlescope to directly visualize the peritoneal space to avoid adhesions and omentum during catheter placement. These percutaneous approaches are minimally invasive procedures that can be performed on an outpatient basis without the need for general anesthesia.

Published: February 2022

AbstractA functional hemodialysis vascular access is the lifeline for patients with end-stage kidney disease and is considered a major determinant of survival and quality of life in this patient population. Hemodialysis therapy can be performed via arteriovenous fistulas, arteriovenous grafts, and central venous catheters (CVCs). Following dialysis vascular access creation, the interplay between several pathologic mechanisms can lead to vascular luminal obstruction due to neointimal hyperplasia with subsequent stenosis, stasis, and eventually access thrombosis. Restoration of the blood flow in the vascular access circuit via thrombectomy is crucial to avoid the use of CVCs and to prolong the life span of the vascular access conduits. The fundamental principles of thrombectomy center around removing the thrombus from the thrombosed access and treating the underlying culprit vascular stenosis. Several endovascular devices have been utilized to perform mechanical thrombectomy and have shown comparable outcomes. Standard angioplasty balloons remain the cornerstone for the treatment of stenotic vascular lesions. The utility of drug-coated balloons in dialysis vascular access remains unsettled due to conflicting results from randomized clinical trials. Stent grafts are used to treat resistant and recurrent stenotic lesions and to control extravasation from a ruptured vessel that is not controlled by conservative measures. Overall, endovascular thrombectomy is the preferred modality of treatment for the thrombosed dialysis vascular conduits.
Patient Selection and Planning for Image-Guided Peritoneal Dialysis Catheter Placement
Authors: Crabtree John H. , Hathaway Peter B. 
Published: February 2022

AbstractImage-guided percutaneous peritoneal dialysis (PD) catheter insertion has become increasingly relied upon to provide urgent access for late presenting kidney failure patients, to overcome surgical backlogs and limited operating room access, to avoid general anesthesia in high-risk patients, and, by itself, as an alternative approach to surgical PD access. Advanced planning for the procedure is essential to assure the best possible outcome. Appropriate selection of patients for percutaneous PD catheter placement, choosing the most suitable catheter type, determining insertion and exit site locations, and final patient preparations facilitate the performance of the procedure, minimizes the risk of complications, and improves the likelihood of providing a successful long-term peritoneal access.
Hemodialysis Catheters: Update on Types, Outcomes, Designs and Complications

Published: February 2022

AbstractHemodialysis catheters (HDCs) are an essential part of kidney replacement therapy. While these catheters are considered only the bridge to long-term vascular access such as arteriovenous fistulas and grafts, they are associated with significant morbidity and mortality and subsequent increased health care expenditures. However, despite these risks, a large proportion of end stage kidney disease population initiates dialysis using these catheters. The pathogenicity of HDCs stems from its invasive nature to the venous vasculature tree resulting in both mechanical and infectious complications. Therefore, the wide use these catheters in dialysis population and the associated complications necessitated continuous innovations in the catheter material, design, and placement techniques. This review provides an update on the catheter types, catheter tip designs, and the new technologies and innovations aimed to improve the catheter functionality and mitigate its related complications.

Published: February 2022

AbstractSolid pseudopapillary tumor (SPT) is an uncommon low-grade malignant cystic exocrine neoplasm of the pancreas that typically affects young women. The tumor has an excellent prognosis after surgical resection. Vascular involvement is usually not seen at presentation. Local recurrence and metastasis are also rare. Herein, we present a case of large, locally advanced SPT in a young female with splenoportal extension and malignant transformation.
Fraught with Friction: Inclusive Development for Informal Workers in Urban Ghana
Authors: Hendriks Tanja D. , Verbuyst Rafael , Kaag Mayke 
Published: February 2022

AbstractInformal workers are a heterogeneous group distinguished by diverse activities and interests, but they have in common that they operate largely outside state regulations. In this article, we analyse the ways in which informal workers in Ghana are organising (themselves) in response to proposed relocations of their workspace. Borrowing from Tsing, we distinguish three layers of friction that can lead to (structural) change, collective action, and an increase in informal workers’ political leverage. Our two case studies in Accra and Kumasi show how striving for inclusive development is a process shaped by diverse agendas and potentially conflicting interests. These relational and political aspects are crucial for understanding the frictions involved, as well as how these may lead to change. Where the tendency is to gloss over these frictions, we argue that they need to be the starting point for effective policies and initiatives for inclusive development.
Wide temperature AC-calorimetry equipped in a constant loading cubic-anvil-type pressure apparatus
Authors: Yamauchi Touru , Ueda Hiroaki 
Published: February 2022

AC-calorimetry was developed for a cubic-anvil-type pressure apparatus, which can explore the electromagnetic properties of matter over temperatures of 2–300 K and pressures of 0–15 GPa. This method was designed to observe the specific heat of fragile crystals that are difficult to mold into desired forms, such as β-Na0.33V2O5 and BaFe2S3. The calorimeter has two main components: a thermometer and a heater. We employed an AuFe (0.07 mol. %)-Chromel thermocouple and NiCr alloy foil/wire as the thermometer and heater, respectively. Using this calorimetry, we successfully observed the pressure dependencies of several transition temperatures in β-Na0.33V2O5 and the jump in the specific heat (ΔCac/T) at the superconducting transition in Pb-metal when under pressure. Meanwhile, the pressure dependencies of the observed ΔCac/T do not coincide with the literature, which may be attributed to the pressure dependence of the thermoelectric power for the AuFe-Chromel thermocouple at around 5 K.
Benchmark studies on the large errors of calculated binding energies in metallophilic interactions

Published: February 2022

Aurophilicity is a d10–d10 closed-shell interaction, which is repulsively calculated by the Hartree–Fork (HF) method, whereas binding energies (Eb) are largely overestimated under the second-order Møller–Plesset (MP2) method, compared to the coupled cluster singles and doubles with perturbative triples [CCSD(T)] method. The unusual energy errors between different wave functional methods were also verified in other closed-shell metallophilic systems and even were taken as a label of metallophilic interaction. Here, we performed a benchmark study on a collection of structures with weak interactions, sp–sp bonds, sp–d bonds, and d–d bonds, to investigate the influence factor of the errors of HF and MP2 methods. It was found that the large energy errors of HF and MP2 methods were not specified for closed-shell interactions, and the errors could also be very large for many covalent bonds, which was strongly related to the azimuthal quantum number of interaction orbitals. Compared to the CCSD(T) method, the MP2 method weakens the s–s covalent interactions slightly, strengthens the p–p covalent interactions slightly, and overestimates the d–d covalent interactions largely (can be −170 kcal/mol for the Re–Re quadruple bond). This benchmark study suggests that the special energy errors in metallophilicity may result from the participation of d orbitals. Benchmark studies on various density functional methods were also given for calculating binding energies of d–d bonds.
Kelp-forest dynamics controlled by substrate complexity
Authors: Randell Zachary , Kenner Michael , Tomoleoni Joseph , Yee Julie , Novak Mark 
Published: February 2022

Significance
Kelp forests are declining worldwide due to varied combinations of environmental change and the trophic downgrading of urchin-controlling predators. These processes have increased the frequency and extent of rapid, nonlinear shifts to so-called urchin barrens whose ecological functioning and services are reduced relative to those of kelp forests. Understanding the factors that regulate kelp-forest tipping points and switches between states is key to their management. Here we demonstrate that substrate complexity (surface rugosity) determines both the existence of and dynamic transition between community states around San Nicolas Island, CA. Kelp-forest conservation and restoration efforts are growing internationally and may benefit from the consideration of substrate complexity in their strategies.
Fully learnable deep wavelet transform for unsupervised monitoring of high-frequency time series

Published: February 2022

SignificanceMonitoring of industrial assets often relies on high-frequency (HF) signal measurements. One difficulty of dealing with such measurements in the industrial context is the conciliation between the high-frequency sampling and low-dimensional decision states (e.g., healthy/unhealthy), in a context where, very often, labels are not available. Here, we propose a fully unsupervised deep-learning framework for high-frequency time series that is able to extract meaningful and sparse representation of raw signals and is able to handle different lengths of time series flexibly, overcoming thereby several of the limitations of existing deep-learning approaches. The decomposition framework will be very useful for handling in an automatic manner high-frequency signals and is an important basis for future applications with HF data.

Significance
As high-power devices approach nanoscale, interface thermal conductance (ITC) becomes a bottleneck to govern the device performance, which is dominated by the interface phonons. In order to gain insights into engineering ITC, here we measure the local phonons across AlN/Si and AlN/Al interfaces by using atomically resolved vibrational electron energy-loss spectroscopy. We find that the dominant types of interface phonons for ITC are very different in these two systems and demonstrate the ability to correlate the measured interface phonons with ITC at atomic scale. Our study reveals the underlying mechanism of ITC and provides useful insights for thermal management in these practically important semiconductors.
Network modeling predicts personalized gene expression and drug responses in valve myofibroblasts cultured with patient sera

Published: February 2022

Significance
A major contributor to heart valve disease is the excessive buildup of scar-like tissue in the valve, which can hinder the ability of the valve to open and close and can ultimately lead to heart failure. Controlling this scar tissue remodeling is very difficult due, in part, to a complex cellular regulation system and, in part, to large variabilities between different patients. We have built a computational model of the cell biochemical network that regulates valve remodeling, which enables virtual predictions of valve scarring given patient-specific biochemical levels. With this model, we ran personalized drug screens to predict each patient’s response to particular therapies, and follow-up cell culture experiments validated our predictions with over 80% accuracy.
The recovered past?

AbstractThe present considerations focus on the intersection of translation and memory. The starting point of these considerations is the lost letter of General Władysław Sikorski to the president of Czechoslovakia, Edvard Beneš, dated 17 February 1941, known only in its German and Czech translations. In the history of translation, there are many known examples of texts saved only through translation that have been incorporated into a cultural system, thereby preserving their continuity. However, this is not what occurred regarding the translation described here. The historical and political context of the correspondence of General Sikorski to President Beneš concerning the post-war expulsion of German populations inclines one to consider the subject of the mutual relationships between collective memory and historical knowledge. The article describes the role of translation as an act of communication in cultural processes, thus in building and transferring knowledge resources, as well as in the processes of constituting collective memory and shaping a memory narrative. The question of the role of the described text centers on – in view of the lack of the original – the issue of its authenticity. It seems that the lack of the original text has become a pretext for excluding from discourse the translation whose content is not in accordance with the official narrative. The fact that it is impossible to settle this question also inclines one to view the translation as a possible tool of manipulation. The authors of the article thus pose the question as to whether the assumption of a transnational perspective would allow the incorporation of this translation into discussions concerning the memory of the expulsions.
A corpus-based comparative study of explicitation by investigating connectives in two Chinese translations of The Lord of the Rings
Authors: Song Hua 
Published: February 2022

Abstract
This article conducts a corpus-based comparative study of explicitation, one of the translation universals widely explored, by investigating the use of connectives in two versions of the Chinese translation of The Lord of the Rings from Taiwan and Mainland China. The two versions are compared with the originally produced Chinese text and their source text to find out whether explicitation through the use of connectives occurs in Chinese translation and to what extent such explicitation is influenced by the source text. A quantitative plus qualitative method is adopted to analyze the connectives in the two Chinese versions and compare them with their counterparts in the source text and the non-translated target text. The results show that explicitation occurs in both versions and that the Taiwan version exhibits a higher degree of explicitation than the Mainland version. Such findings may result from different pedagogical and regional translation norms, especially with greater importance attached to faithfulness in translation in Mainland China.

Published: February 2022

ABSTRACTThe present study aimed to test the hypothesis that changes in the dermal tissue dielectric constant (TDC) and biomechanical properties of the skin would be correlated with the indicators related to dehydration. Ten healthy adult men were enrolled in three trials: no fluid intake (DEH), ad libitum fluid intake (AL‐HYD), and programmed fluid intake (P‐HYD) after exercise in a randomised crossover design. The participants performed a pedalling exercise at 60% heart rate reserve until 2% body mass loss. At 120 min after exercise, an incremental exercise test was carried out. Aerobic capacity, body composition, TDC, biomechanical properties of the skin (pliability, viscoelasticity, and total recovery), and indicators related to dehydration in the serum and urine were measured before and 120 min after exercise. Higher values of the pliability and viscoelasticity, and lower value of the total recovery on the hand were demonstrated in the P‐HYD trial compared to the DEH trial (all P < 0.05). Changes in the TDC were significantly correlated with changes in body mass, total body water, serum osmolarity, and hematocrit (all P < 0.05). Changes in the biomechanical properties of the hand were significantly correlated with changes in body mass, hematocrit, and urine specific gravity (all P < 0.05). The present study showed that the changes in skin characteristics correlated with the body water and dehydration‐associated indicators in the serum and urine, thus suggesting that skin characteristics may be useful in the assessment of dehydration.Highlights
This study was the first to investigate the effect of dehydration and rehydration on the TDC and biomechanical properties of the skin upon instrumental measure, and not manual testing.
This study confirmed the decline in aerobic capacity by dehydration and immediate recovery with sufficient rehydration.
Changes in the TDC and the biomechanical properties of the skin correlated with the body water and dehydration‐associated indicators in the serum and urine.
Skin characteristics may be useful in the assessment of dehydration.

Published: February 2022

Main text
This report describes a CIPM Key Comparison through the SIM/MWG-7 organization, concerning instrumented impact testing of low-energy (20 J) and high-energy (100 J) Charpy V-notch specimens.
In this Comparison, various instrumented and non-instrumented data were obtained from instrumented Charpy tests performed at the pilot (NIST) and participant (INMETRO) laboratories using the same instrumented Charpy striker and acquisition system.
The use of instrumented absorbed energy (Wt), rather than absorbed energy yielded by the impact machine encoder or dial gage (KV), guarantees traceability to the International System and offers the promise of reducing bias between NMIs and simplifying comparisons between certification systems.

Main text
The CCQM Isotope Ratio Working Group (IRWG) determined that an additional key comparison of carbon isotope delta measurements was required to capture the progress of this field. Vials containing 0.25 mg of vanillin were prepared at NRC, and evaluated for bottle-to-bottle homogeneity prior to distribution to the eight participating institutes. Participants were able to choose any suitable method and reference materials for carbon isotope delta measurements, and report a carbon isotope delta value and the associated uncertainty, and analysis details. To determine the key comparison reference value (KCRV) and its associated uncertainty, the NRC in collaboration with the NIST, developed a multivariate Bayesian random laboratory effects model, which also incorporates the uncertainty due to bottle-to-bottle homogeneity and any correlations between the reported results that arise due to the use of common reference materials. The KCRV for this study was determined to be -25.833 ‰ relative to the VPDB, with associated uncertainty of 0.028 ‰, and expanded uncertainty of 0.056 ‰ (k=2). All the results reported by the participants in this study were considered equivalent to the KCRV.
