Association between Living Kidney Donor Post-Donation Hypertension and Recipient Graft Failure.

BACKGROUND Recipients of kidneys from living donors who subsequently develop ESRD also have higher graft failure, suggesting the two donor kidneys share risk factors that could inform recipient outcomes. Given that donor ESRD is rare, an earlier and more common post-donation outcome could serve as a surrogate to individualize counseling and management for recipients. Hypertension is a frequent event prior to donor ESRD; thus early post-donation hypertension might indicate higher risk of graft failure. METHODS We studied SRTR data to quantify the association between early post-donation hypertension and recipient graft failure using propensity score-weighted Cox proportional hazards regression. We also examined the association between post-donation systolic blood pressure and graft failure. RESULTS Of 37,901 recipients, 2.4% had a donor who developed hypertension within 2 years post-donation. Controlling for donor and recipient characteristics, recipients whose donors developed hypertension had no higher risk for graft failure (aHR 1.03, 95% CI 0.85-1.25, p=0.72). This was consistent among subgroups of recipients at higher risk for adverse outcomes due to hyperfiltration: African American recipients (aHR 1.10, 95% CI 0.70-1.73, p=0.68) and those with ESRD caused by hypertension (aHR 1.10, 95% CI 0.65-1.85, p=0.73) or diabetes (aHR 0.80, 95% CI 0.56-1.13, p=0.20). However, graft failure was associated with post-donation systolic blood pressure (per 10 mmHg, aHR 1.05, 95% CI 1.03-1.08, p<0.001). CONCLUSION Although post-donation systolic blood pressure is associated with graft failure, the reported diagnosis of hypertension as determined by the requirement for blood pressure treatment early post-donation did not portend a higher risk of recipient graft failure in the same way as eventual post-donation ESRD.
STG-CT: High-vacuum plume test facility for chemical thrusters

The STG-CT, operated by the DLR Institute for Aerodynamics and Flow Technology in Gottingen, is a vacuum facility specically designed to provide and maintain a space-like vacuum environment for researching plume flow and plume impingement from satellite reaction control thrusters. Its unique liquid-helium driven cryopump of 30m2 allows maintaining a background pressure <10^-5 mbar even when molecular hydrogen is a plume constituent.
The Actuation Mechanism of 3D Printed Flexure-Based Robotic Microtweezers

We report on the design and the modeling of a three-dimensional (3D) printed flexure-based actuation mechanism for robotic microtweezers, the main body of which is a single piece of nylon. Our design aims to fill a void in sample manipulation between two classes of widely used instruments: nano-scale and macro-scale robotic manipulators. The key component is a uniquely designed cam flexure system, which linearly translates the bending of a piezoelectric bimorph actuator into angular displacement. The 3D printing made it possible to realize the fabrication of the cam with a specifically calculated curve, which would otherwise be costly using conventional milling techniques. We first characterized 3D printed nylon by studying sets of simple cantilevers, which provided fundamental characteristics that could be used for further designs. The finite element method analysis based on the obtained material data matched well with the experimental data. The tweezers showed angular displacement from 0° to 10° linearly to the deflection of the piezo actuator (0–1.74 mm) with the linearity error of 0.1°. Resonant frequency of the system with/without working tweezer tips was discovered as 101 Hz and 127 Hz, respectively. Our design provides simple and low-cost construction of a versatile manipulator system for samples in the micro/meso-scale (0.1–1 mm).
Engineering a bioluminescent bioreporter from an environmentally sourced mercury‐resistant Enterobacter cloacae strain for the detection of bioavailable mercury

Escherichia coli is the conventional choice as the host strain for whole‐cell bioreporter construction due to its well‐understood genetics and well‐established cloning protocols. However, for real‐world environmental biosensing applications, it is often beneficial to use a bacterial strain derived directly from the environment under study to better ensure chemical target specificity and optimal response time. The aim of this study was to develop a whole‐cell bioreporter for detection of bioavailable mercury by replacing E. coli with a wild‐type bacterial host derived from a soil environment.
Impact of a National Private Health Insurer’s Prior Authorization Policy on Utilization of Vaginal Hysterectomy

Objectives On April 6, 2015, the largest private health insurer in the United States implemented a policy requiring prior authorization for all hysterectomies except those done as outpatient vaginal. The purpose of this policy was to increase utilization of vaginal hysterectomy; however, it is unknown whether this policy had its intended effect. We sought to analyze trends in hysterectomy routes before and after implementation of the prior authorization policy to see if utilization of vaginal hysterectomy increased. Methods This was a retrospective study using the Optum Clinformatics Data Mart national claims database of women enrolled in a single national private health insurer who underwent hysterectomy for any indication between January 1, 2010, and June 30, 2016. Per-quarter utilization of hysterectomy routes (abdominal, laparoscopic, vaginal, and laparoscopic-assisted vaginal) was compared between the prepolicy and postpolicy periods using interrupted time series analyses. Results Data for 305,139 hysterectomies were available—248,821 in the prepolicy period and 56,318 in the postperiod. Outpatient vaginal hysterectomy had the greatest increase in utilization of all routes and types; the average utilization per quarter in the prepolicy period was −0.61%, and this increased to 0.21% in the postpolicy period (P < 0.0001). Outpatient laparoscopic hysterectomy had the greatest decrease in utilization, with an average decrease of −1.50% per quarter. Conclusions The prior authorization policy was associated with a short-term increase in utilization of vaginal hysterectomy.
Molecularly Imprinted Polymer-Based Hybrid Materials for the Development of Optical Sensors

We report on the development of new optical sensors using molecularly imprinted polymers (MIPs) combined with different materials and explore the novel strategies followed in order to overcome some of the limitations found during the last decade in terms of performance. This review pretends to offer a general overview, mainly focused on the last 3 years, on how the new fabrication procedures enable the synthesis of hybrid materials enhancing not only the recognition ability of the polymer but the optical signal. Introduction describes MIPs as biomimetic recognition elements, their properties and applications, emphasizing on each step of the fabrication/recognition procedure. The state of the art is presented and the change in the publication trend between electrochemical and optical sensor devices is thoroughly discussed according to the new fabrication and micro/nano-structuring techniques paving the way for a new generation of MIP-based optical sensors. We want to offer the reader a different perspective based on the materials science in contrast to other overviews. Different substrates for anchoring MIPs are considered and distributed in different sections according to the dimensionality and the nature of the composite, highlighting the synergetic effect obtained as a result of merging both materials to achieve the final goal.
Systematic Assessment of Burst Impurity in Confocal-Based Single-Molecule Fluorescence Detection Using Brownian Motion Simulations

Single-molecule fluorescence detection (SMFD) experiments are useful in distinguishing sub-populations of molecular species when measuring heterogeneous samples. One experimental platform for SMFD is based on a confocal microscope, where molecules randomly traverse an effective detection volume. The non-uniformity of the excitation profile and the random nature of Brownian motion, produce fluctuating fluorescence signals. For these signals to be distinguished from the background, burst analysis is frequently used. Yet, the relation between the results of burst analyses and the underlying information of the diffusing molecules is still obscure and requires systematic assessment. In this work we performed three-dimensional Brownian motion simulations of SMFD, and tested the positions at which molecules emitted photons that passed the burst analysis criteria for different values of burst analysis parameters. The results of this work verify which of the burst analysis parameters and experimental conditions influence both the position of molecules in space when fluorescence is detected and taken into account, and whether these bursts of photons arise purely from single molecules, or not entirely. Finally, we show, as an example, the effect of bursts that are not purely from a single molecule on the accuracy in single-molecule Förster resonance energy transfer measurements.
Highly Stretchable Metallic Nanowire Networks Reinforced by the Underlying Randomly Distributed Elastic Polymer Nanofibers via Interfacial Adhesion Improvement

On‐skin electronics require conductive, porous, and stretchable materials for a stable operation with minimal invasiveness to the human body. However, porous elastic conductors that simultaneously achieve high conductivity, good stretchability, and durability are rare owing to the lack of proper design for good adhesion between porous elastic polymer and conductive metallic networks. Here, a simple fabrication approach for porous nanomesh‐type elastic conductors is shown by designing a layer‐by‐layer structure of nanofibers/nanowires (NFs/NWs) via interfacial hydrogen bonding. The as‐prepared conductors, consisting of Ag NWs and polyurethane (PU) NFs, simultaneously achieve high conductivity (9190 S cm−1), high stretchability (310%), and good durability (82% resistance increase after 1000 cycles of deformation at 70% tensile strain). The direct contact between the Ag NWs enables the high conductivity. The synergistic effect of the layer‐by‐layer structure and good adhesion between the Ag NWs and the PU NFs enables good mechanical properties. Furthermore, without any adhesive gel/tape, the conductors can be utilized as breathable strain sensors for precise joint motion monitoring, and as breathable sensing electrodes for continuous electrophysiological signal recording.
A systematic review and meta-analysis of the effects of cardiac rehabilitation interventions on cognitive impairment following stroke

Abstract Purpose The cardiac rehabilitation model has potential as an approach to providing rehabilitation following stroke. This review aims to identify evidence for the participation of stroke patients in cardiac/cardiovascular rehabilitation programs internationally, whether or not such programs offer a cognitive intervention as part of treatment, and the impact of rehabilitation on post-stroke cognitive function. Method Five electronic databases were searched from inception to 1 May 2019, namely: MEDLINE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Central Register of Controlled Trials, and the Web of Science. Eligible studies included both randomized and non-randomized studies of cardiac rehabilitation-type interventions which measured cognitive function in patients with transient ischemic attack (TIA) or stroke. Results Of 14,153 records reviewed, nine studies which delivered cardiac rehabilitation-type interventions to stroke patients were finally included. Only three of these studies delivered cognitive rehabilitation as part of the intervention. Cardiac rehabilitation had no statistically significant effect on cognitive function in five randomized controlled trials (standardized mean difference= 0.28, 95% CI= −0.16 to 0.73) or in three one group pre-post studies (standardized mean difference= 0.15, 95% CI= −0.03 to 0.33). Conclusions This review highlights that there are very few studies of delivery of cardiac rehabilitation to stroke patients and that the inclusion of cognitive interventions is even less common, despite the high prevalence of post-stroke cognitive impairment. IMPLICATIONS FOR REHABILITATION The cardiac rehabilitation model has the potential to be expanded to include patients post-stroke given the commonality of secondary prevention needs, thereby becoming a cardiovascular rehabilitation model. Up to half of patients experience cognitive impairment after stroke; suggesting that a post-stroke cardiovascular rehabilitation model should incorporate specific cognitive strategies for patients. This systematic review identified three cardiovascular rehabilitation programmes which delivered cognitive rehabilitation as part of treatment; however, evidence for efficacy is weak.
Self-Reported Oral Health Related Behaviour and Gum Bleeding of Adolescents in Slovakia in Relation to Socioeconomic Status of Their Parents: Cross-Sectional Study Based on Representative Data Collection

Background: Oral health strongly affects overall health and is related to many factors. The aim of our study was to analyse oral health related behaviours (OHRBs) and gum bleeding among Slovak adolescents and assess the effect of socioeconomic factors on the outcomes. Methods: Data from the Health Behaviour in School-aged Children study (HBSC) were used (N = 8896, age range = 10–16 years, M = 13.4; SD = 1.4; 50.9% boys). Sociodemographic and socioeconomic indicators and frequency of OHRBs (dental hygiene, toothbrush changing, preventive check-up) and gum bleeding were collected. Effects of sociodemographic and socioeconomic variables on outcome variables were analysed by binary logistic regression. Results: We found that prevalence of OHRBs slightly decreases with age, and worse outcomes were reported by boys compared to girls (OHRB odds ratio range 0.45–0.75, (95% C.I. range 0.40–0.91), gum bleeding 1.38 (95% C.I. 1.19–1.61), p < 0.05). OHRBs were in most cases significantly associated with socioeconomic variables, lower affluence predicts worse outcomes (odds ratio range 0.76–0.88 (95% C.I. range 0.68–0.96), p < 0.05). Conclusion: Our study provides representative findings on ORHBs in Slovakia and shows important associations of socioeconomic factors related to adolescents’ oral health issues.
Zerumbone Induces Apoptosis in Breast Cancer Cells by Targeting αvβ3 Integrin upon Co-Administration with TP5-iRGD Peptide

Cell-penetrating peptides (CPPs) are highly promising tools to deliver therapeutic molecules into tumours. αVβ3 integrins are cell–matrix adhesion receptors, and are considered as an attractive target for anticancer therapies owing to their roles in the process of metastasis and angiogenesis. Therefore, this study aims to assess the effect of co-administration of zerumbone (ZER) and ZERencapsulated in hydroxypropyl-β-cyclodextrin with TP5-iRGD peptide towards cell cytotoxicity, apoptosis induction, and proliferation of normal and cancerous breast cells utilizing in vitro assays, as well as to study the molecular docking of ZER in complex with TP5-iRGD peptide. Cell viability assay findings indicated that ZER and ZERencapsulated in hydroxypropyl-β-cyclodextrin (ZER-HPβCD) inhibited the growth of estrogen receptor positivebreast cancer cells (ER+ MCF-7) at 72 h treatment with an inhibitory concentration (IC)50 of 7.51 ± 0.2 and 5.08 ± 0.2 µg/mL, respectively, and inhibited the growth of triple negative breast cancer cells (MDA-MB-231) with an IC50 of 14.96 ± 1.52 µg/mL and 12.18 ± 0.7 µg/mL, respectively. On the other hand, TP5-iRGD peptide showed no significant cytotoxicity on both cancer and normal cells. Interestingly, co-administration of TP5-iRGD peptide in MCF-7 cells reduced the IC50 of ZER from 7.51 ± 0.2 µg/mL to 3.13 ± 0.7 µg/mL and reduced the IC50 of ZER-HPβCD from 5.08 ± 0.2 µg/mL to 0.49 ± 0.004 µg/mL, indicating that the co-administration enhances the potency and increases the efficacy of ZER and ZER-HPβCD compounds. Acridine orange (AO)/propidium iodide (PI) staining under fluorescence microscopy showed evidence of early apoptosis after 72 h from the co-administration of ZER or ZER-HPβCD with TP5-iRGD peptide in MCF-7 breast cancer cells. The findings of the computational modelling experiment provide novel insights into the ZER interaction with integrin αvβ3 in the presence of TP5-iRGD, and this could explain why ZER has better antitumor activities when co-administered with TP5-iRGD peptide.
Antimycotic Efficacy and Safety of a New Cold Corneal Storage Medium by Time-Kill and Toxicity Studies.

PURPOSE To evaluate a new corneal cold storage medium including an antimycotic tablet (Kerasave, AL.CHI.MI.A. S.r.l.). METHODS Kerasave and tryptone soy broth (control) were inoculated with 10 and 10 colony-forming units (CFU)/mL of 6 Candida isolates (Candida albicans [n = 4], Candida tropicalis [n = 1], and Candida glabrata [n = 1]). Minimum inhibitory concentrations (MICs) were determined using amphotericin B Etest strips. Sterile porcine corneas contaminated with 10 CFU/mL of each isolate were incubated in Kerasave and control at 4°C. Growth rate and Log10 reduction at 4°C at different time intervals were determined for liquid samples and tissue homogenates. Kerasave biocompatibility was assessed according to ISO 10993-5 and ISO 10993-10. RESULTS No C. albicans or C. tropicalis colonies were recovered from Kerasave inoculated with 10 CFU/mL after incubation for 3 days at 4°C. C. glabrata was inhibited but not killed after 3 days at 4°C. Four of the 6 strains contaminated with 10 CFU/mL demonstrated a significant ≥ 3 Log10 reduction in media and tissue homogenates within 5 days as compared to controls (p < 0.01). Amphotericin B MICs ranged from 0.19 to 0.38 μg/mL for C. albicans (n = 3) and C. tropicalis (n = 1). C. glabrata showed reduced susceptibility (0.5 μg/mL) and 1 C. albicans was resistant to amphotericin B (≥ 1 μg/mL). Kerasave was not cytotoxic, irritating, or sensitizing according to the ISO standards. CONCLUSIONS Kerasave showed high antifungal efficacy against susceptible fungal strains at 4°C in the presence and absence of corneal tissue. Resistant strains to amphotericin B were not eliminated by Kerasave. Kerasave is not cytotoxic, irritating, or sensitizing.
Charcot-Marie-Tooth: From Molecules to Therapy

Charcot-Marie-Tooth (CMT) is the most prevalent category of inherited neuropathy. The most common inheritance pattern is autosomal dominant, though there also are X-linked and autosomal recessive subtypes. In addition to a variety of inheritance patterns, there are a myriad of genes associated with CMT, reflecting the heterogeneity of this disorder. Next generation sequencing (NGS) has expanded and simplified the diagnostic yield of genes/molecules underlying and/or associated with CMT, which is of paramount importance in providing a substrate for current and future targeted disease-modifying treatment options. Considerable research attention for disease-modifying therapy has been geared towards the most commonly encountered genetic mutations (PMP22, GJB1, MPZ, and MFN2). In this review, we highlight the clinical background, molecular understanding, and therapeutic investigations of these CMT subtypes, while also discussing therapeutic research pertinent to the remaining less common CMT subtypes.
Physical and Functional Analysis of Viral RNA Genomes by SHAPE.

RNA viruses encode the information required to usurp cellular metabolism and gene regulation and to enable their own replication in two ways: in the linear sequence of their RNA genomes and in higher-order structures that form when the genomic RNA strand folds back on itself. Application of high-resolution SHAPE (selective 2'-hydroxyl acylation analyzed by primer extension) structure probing of viral RNA genomes has identified numerous new regulatory elements, defined new principles by which viral RNAs interact with the cellular host and evade host immune responses, and revealed relationships between virus evolution and RNA structure. This review summarizes our current understanding of genome structure-function interrelationships for RNA viruses, as informed by SHAPE probing, and outlines opportunities for future studies. Expected final online publication date for the Annual Review of Virology Volume 6 is September 30, 2019. Please see http://www.annualreviews. org/page/journal/pubdates for revised estimates.

Genetically Engineered-MSC Therapies for Non-unions, Delayed Unions and Critical-size Bone Defects

The normal bone regeneration process is a complex and coordinated series of events involving different cell types and molecules. However, this process is impaired in critical-size/large bone defects, with non-unions or delayed unions remaining a major clinical problem. Novel strategies are needed to aid the current therapeutic approaches. Mesenchymal stem/stromal cells (MSCs) are able to promote bone regeneration. Their beneficial effects can be improved by modulating the expression levels of specific genes with the purpose of stimulating MSC proliferation, osteogenic differentiation or their immunomodulatory capacity. In this context, the genetic engineering of MSCs is expected to further enhance their pro-regenerative properties and accelerate bone healing. Herein, we review the most promising molecular candidates (protein-coding and non-coding transcripts) and discuss the different methodologies to engineer and deliver MSCs, mainly focusing on in vivo animal studies. Considering the potential of the MSC secretome for bone repair, this topic has also been addressed. Furthermore, the promising results of clinical studies using MSC for bone regeneration are discussed. Finally, we debate the advantages and limitations of using MSCs, or genetically-engineered MSCs, and their potential as promoters of bone fracture regeneration/repair.

In vivo antibacterial activity of Zataria multiflora Boiss extract and its components, carvacrol, and thymol, against colistin‐resistant Acinetobacter baumannii in a pneumonic BALB/c mouse model

Acinetobacter baumannii has emerged as a major cause of nosocomial infections. Various resistance mechanisms of A. baumannii against antibiotics have transformed it into a successful nosocomial pathogen. Because of the limited number of available antibiotics, we used a medicinal plant with an antibacterial effect. Zataria multiflora Boiss (ZMB) extract and its components were used for the treatment of pneumonic mice infected with A. baumannii. The biological effects of this extract and the regulation of the outer membrane protein A (ompA) gene were used in a mouse model.
