Long-term Outcome of Renal Transplantation in Patients with Congenital Lower Urinary Tract Malformations: A Multicenter Study

Background. Renal insufficiency can occur in patients with congenital lower urinary tract malformations (LUTM) even when managed during infancy. Data in the current literature concerning this subject remain sparse. The aim of this study was to report the feasibility and long-term results of renal transplantation during adulthood in patients with a congenital LUTM. Methods. A retrospective multicenter study from 3 French renal transplant centers was conducted, including 123 transplantations on 112 patients with LUTM (1996–2016). Graft survival, patient survival, and complications were analyzed. Results were stratified according to the underlying uropathy and the type of initial management during childhood or before transplantation. Results. In this study, patients suffering from posterior urethral valves (n = 49), spina bifida (n = 21), central neurogenic bladder (n = 13), bladder exstrophy (n = 14), prune belly syndrome (n = 12), Hinman syndrome (n = 6), urogenital sinus (n = 4), and other pathologies (n = 4) were included. The mean age at transplantation was 32.1 years old (±11.2). The mean follow-up period was 7.2 years. Patient survival at 1, 5, 10, and 15 years was 97.4%, 93.0%, 89.4%, and 80.0%, respectively. Graft survival at 1, 5, 10, 15, and 20 years was 96.6%, 87.6%, 77.3%, 60.6%, and 36.4%, respectively. Enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute pyelonephritis (P = 0.02). There was no difference in graft survival when transplantation was performed on an enterocystoplasty or urinary diversions compared with a native bladder, provided a well-conducted bladder management. Conclusions. Even though enterocystoplasty and continent urinary diversions exposed grafts to more frequent acute graft pyelonephritis, patient and graft survival rates in LUTM at 10 years were similar to other kidney transplantations on native bladders.
Inflammatory Bowel Disease Serological Immune Markers Anti-Saccharomyces cerevisiae Mannan Antibodies and Outer Membrane Porin C are Potential Biomarkers for Hirschsprung-associated Enterocolitis.

OBJECTIVE Hirschsprung-associated enterocolitis (HAEC) is the most frequent complication in Hirschsprung disease (HSCR) patients. Currently HAEC is diagnosed clinically, leaving uncertainty in the diagnosis thereby potentially leading to over- or undertreatment of patients. The aim of this study was to identify immune biomarkers to aid in the diagnosis of HAEC. METHODS From 2012 to 2017, 43 children with HSCR enrolled in a multicenter study, underwent retrospective evaluation of their medical records, and questionnaire-directed parent interviews. HAEC status was determined using HAEC score with cutoff ≥4. Plasma was collected and analyzed by ELISA for the inflammatory bowel disease-associated antibodies: anti-Saccharomyces cerevisiae mannan antibodies (ASCA), outer membrane porin C (OmpC), CBir1, antineutrophil cytoplasmic antibodies. Data were analyzed using t test, univariate, multivariable, and binomial regression models. RESULTS Eighteen patients had at least 1 episode of HAEC, 25 had no history of HAEC. The HAEC and NO HAEC groups had similar median ages (3 years) and family histories of HSCR. The HAEC group showed markedly elevated ASCA IgA and OmpC antibody levels compared with the NO HAEC group, whereas CBir1 and antineutrophil cytoplasmic antibodies were similar between the groups. Both univariate and multivariable analysis revealed higher OmpC antibody levels associated with HAEC (odds ratio 1.39, confidence interval 1-1.92, P = 0.048), whereas univariate analysis identified a trend toward elevated IgA and immunoglobulin G ASCA levels with HAEC. CONCLUSIONS We identified elevated OmpC and ASCA serum antibody levels in HAEC patients, and that increased OmpC antibody levels correlated with HAEC occurrence, suggesting HAEC and Crohn disease share gut microbial-host immune responses. These antibodies may serve as potential biomarkers for HAEC, although prospective study with larger sample size is needed.
Respiratory sinus arrhythmia is a major component of heart rate variability in undisturbed, remotely monitored rattlesnakes, Crotalus durissus

ABSTRACT ECG recordings were obtained using an implanted telemetry device from the South American rattlesnake, Crotalus durissus, held under stable conditions without restraining cables or interaction with researchers. Mean heart rate (fH) recovered rapidly (<24 h) from anaesthesia and operative procedures. This preceded a more gradual development of heart rate variability (HRV), with instantaneous fH increasing during each lung ventilation cycle. Atropine injection increased mean fH and abolished HRV. Complete autonomic blockade revealed a cholinergic tonus on the heart of 55% and an adrenergic tonus of 37%. Power spectral analysis of HRV identified a peak at the same frequency as ventilation. This correlation was sustained after temperature changes and it was more evident, marked by a more prominent power spectrum peak, when ventilation is less episodic. This HRV component is homologous to that observed in mammals, termed respiratory sinus arrhythmia (RSA). Evidence for instantaneous control of fH indicated rapid conduction of activity in the cardiac efferent nervous supply, as supported by the description of myelinated fibres in the cardiac vagus. Establishment of HRV 10 days after surgical intervention seems a reliable indicator of the re-establishment of control of integrative functions by the autonomic nervous system. We suggest that this criterion could be applied to other animals exposed to natural or imposed trauma, thus improving protocols involving animal handling, including veterinarian procedures. Summary: Respiratory sinus arrhythmia constitutes a major component of heart rate variability (HRV) in remotely monitored rattlesnakes. Detection of HRV is posited as a reliable indicator of recovery from trauma in animals.
Tissue Oxygenation in Response to Different Relative Levels of Blood-Flow Restricted Exercise

Blood flow restrictive (BFR) exercise elicits a localized hypoxic environment compatible with greater metabolic stress. We intended to compare the acute changes in muscle microvascular oxygenation following low-intensity knee extension exercise, combined with different levels of BFR. Thirteen active young men (age: 23.8 ± 5.4 years) were tested for unilateral knee extension exercise (30 + 15 + 15 + 15 reps at 20% one repetition maximum) on four different conditions: no-BFR (NOBFR), 40, 60, and 80% of arterial occlusion pressure (AOP). Deoxyhemoglobin+myoglobin concentration Deoxy[Hb+Mb], total hemoglobin [T(H+Mb)] and tissue oxygen saturation [TOI] were measured on the vastus lateralis muscle using near-infrared spectroscopy (NIMO, Nirox srl, Brescia, Italy). The magnitude of change in Deoxy[Hb+Mb]during exercise was similar between 60 and 80% AOP. Overall, compared to that seen during 60 and 80% AOP, NOBFR as well as 40% AOP resulted in a lower magnitude of change in Deoxy[Hb+Mb] (p < 0.05). While the oxygen extraction decreased during each inter-set resting interval in NOBFR and 40% AOP, this was not the case for 60 or 80% AOP. Additionally, TOI values obtained during recovery from each set of exercise were similarly affected by all conditions. Finally, our data also show that, when performed at higher restrictive values (60 and 80%), BFR exercise increases total Deoxy[Hb+Mb] extraction (p < 0.05). Taken together, we provide evidence that BFR is effective for increasing deoxygenation and reducing tissue oxygenation during low-intensity exercise. We also showed that when using low loads, a relative pressure above 40% of the AOP at rest is required to elicit changes in microvascular oxygenation compared with the same exercise with unrestricted conditions.
Sports Training Principles.

Progression Description: The gradual and systematic increases in training stress to maintain tissue overload and, thus, provoke continued training adaptation (2). Concept: As fitness/performance improves with training, training variables (i.e., frequency, intensity, volume) must be increased to induce further adaptation. Rate of progression is important; progressing too rapidly can result in injury while progressing too slowly will delay goal attainment (2). Example: A weight lifter can comfortably lift a weight that used to be a challenge, so she must now lift heavier weights to continue gaining strength.
Prevalence of BRCA1 and BRCA2 gene mutations in Chinese patients with high‐risk breast cancer

Breast cancer is the most common cancer among women worldwide. Here, we report the prevalence of BRCA1/2 mutations in patients with high‐risk breast cancer from Inner Mongolia and Jilin, China, which was a part of a nationwide project on the detection of BRCA1/2 mutations in Chinese patients with hereditary breast cancer.
The Biological Effects of Double-Dose Alpha-1 Antitrypsin Augmentation Therapy. A Pilot Clinical Trial

Rationale: Augmentation therapy with intravenous AAT (alpha-1 antitrypsin) is the only specific therapy for individuals with pulmonary disease from AAT deficiency (AATD). The recommended standard dose (SD; 60 mg/kg/wk) elevates AAT trough serum levels to around 50% of normal; however, outside of slowing emphysema progression, its effects in other clinical outcomes have not been rigorously proven. Objectives: To evaluate the biological effects of normalizing AAT trough levels with double-dose (DD) therapy (120 mg/kg/wk) in subjects with AATD already receiving SD therapy. Methods: Clinically stable subjects were evaluated after 4 weeks of SD therapy, followed by 4 weeks of DD therapy, and 4 weeks after return to SD therapy. At the end of each phase, BAL fluid (BALF) and plasma samples were obtained. Measurements and Main Results: DD therapy increased trough AAT levels to normal and, compared with SD therapy, reduced serine protease activity in BALF (elastase and cathepsin G), plasma elastase footprint (Aα-Val360), and markers of elastin degradation (desmosine/isodesmosine) in BALF. DD therapy also further downregulated BALF ILs and cytokines including Jak-STAT (Janus kinases–signal transducer and activator of transcription proteins), TNFα (tumor necrosis factor-α), and T-cell receptor signaling pathways, cytokines involved in macrophage migration, eosinophil recruitment, humoral and adaptive immunity, neutrophil activation, and cachexia. On restarting SD after DD treatment, a possible carryover effect was seen for several biological markers. Conclusions: Subjects with AATD on SD augmentation therapy still exhibit inflammation, protease activity, and elastin degradation that can be further improved by normalizing AAT levels. Higher AAT dosing than currently recommended may lead to enhanced clinical benefits and should be explored further. Clinical trial registered with www.clinicaltrials. gov (NCT 01669421).
Definition of excessive daytime sleepiness in the general population: Feeling sleepy relates better to sleep‐related symptoms and quality of life than the Epworth Sleepiness Scale score. Results from an epidemiological study

Many different subjective tools are being used to measure excessive daytime sleepiness (EDS) but the most widely used is the Epworth Sleepiness Scale (ESS). However, it is unclear if using the ESS is adequate on its own when assessing EDS. The aim of this study was to estimate the characteristics and prevalence of EDS using the ESS and the Basic Nordic Sleep Questionnaire (BNSQ) in general population samples. Participants aged 40 years and older answered questions about sleepiness, health, sleep‐related symptoms and quality of life. Two groups were defined as suffering from EDS: those who scored >10 on the ESS (with increased risk of dozing off) and those reporting feeling sleepy during the day ≥3 times per week on the BNSQ. In total, 1,338 subjects (53% male, 74.1% response rate) participated, 13.1% reported an increased risk of dozing off, 23.2% reported feeling sleepy and 6.4% reported both. The prevalence of restless leg syndrome, nocturnal gastroesophageal reflux, difficulties initiating and maintaining sleep and nocturnal sweating was higher among subjects reporting feeling sleepy compared to non‐sleepy subjects. Also, subjects reporting feeling sleepy had poorer quality of life and reported more often feeling unrested during the day than non‐sleepy subjects. However, subjects reporting increased risk of dozing off (ESS > 10) without feeling sleepy had a similar symptom profile as the non‐sleepy subjects. Therefore, reporting only risk of dozing off without feeling sleepy may not reflect problematic sleepiness and more instruments in addition to ESS are needed when evaluating daytime sleepiness.
m6A-mRNA methylation regulates cardiac gene expression and cellular growth

This study provides evidence that m6A methylation is dynamically regulated during human and murine cardiac disease and highlights an important role of the m6A methylase Mettl3 in regulating cardiac growth by gene expression control. Conceptually similar to modifications of DNA, mRNAs undergo chemical modifications, which can affect their activity, localization, and stability. The most prevalent internal modification in mRNA is the methylation of adenosine at the N6-position (m6A). This returns mRNA to a role as a central hub of information within the cell, serving as an information carrier, modifier, and attenuator for many biological processes. Still, the precise role of internal mRNA modifications such as m6A in human and murine-dilated cardiac tissue remains unknown. Transcriptome-wide mapping of m6A in mRNA allowed us to catalog m6A targets in human and murine hearts. Increased m6A methylation was found in human cardiomyopathy. Knockdown and overexpression of the m6A writer enzyme Mettl3 affected cell size and cellular remodeling both in vitro and in vivo. Our data suggest that mRNA methylation is highly dynamic in cardiomyocytes undergoing stress and that changes in the mRNA methylome regulate translational efficiency by affecting transcript stability. Once elucidated, manipulations of methylation of specific m6A sites could be a powerful approach to prevent worsening of cardiac function.
Increase of invasive meningococcal serogroup W disease in Europe, 2013 to 2017

Background The total incidence of invasive meningococcal disease (IMD) in Europe has been declining in recent years; however, a rising incidence due to serogroup W (MenW), predominantly sequence type 11 (ST-11), clonal complex 11 (cc11), was reported in some European countries. Aim The aim of this study was to compile the most recent laboratory surveillance data on MenW IMD from several European countries to assess recent trends in Europe. Methods In this observational, retrospective study, IMD surveillance data collected from 2013–17 by national reference laboratories and surveillance units from 13 European countries were analysed using descriptive statistics. Results The overall incidence of IMD has been stable during the study period. Incidence of MenW IMD per 100,000 population (2013: 0.03; 2014: 0.05; 2015: 0.08; 2016: 0.11; 2017: 0.11) and the proportion of this serogroup among all invasive cases (2013: 5% (116/2,216); 2014: 9% (161/1,761); 2015: 13% (271/2,074); 2016: 17% (388/2,222); 2017: 19% (393/2,112)) continuously increased. The most affected countries were England, the Netherlands, Switzerland and Sweden. MenW was more frequent in older age groups (≥ 45 years), while the proportion in children (< 15 years) was lower than in other age groups. Of the culture-confirmed MenW IMD cases, 80% (615/767) were caused by hypervirulent cc11. Conclusion During the years 2013–17, an increase in MenW IMD, mainly caused by MenW cc11, was observed in the majority of European countries. Given the unpredictable nature of meningococcal spread and the epidemiological potential of cc11, European countries may consider preventive strategies adapted to their contexts.
Role of oral health-related behaviors in education inequalities in chronic periodontitis among Sri Lankan men.

AIMS The aims of the present study were to determine education inequalities in chronic periodontitis (CP) among Sri Lankan men and whether oral health behaviors explain education inequalities in CP. METHODS Data from 720 males who participated in a study to determine the prevalence of CP in 30-60-year-olds in Colombo district, Sri Lanka, were used for the present study. An interviewer administered a questionnaire obtained information about sociodemographics and oral health behaviors. Following the assessment of periodontal parameters, case definitions proposed by the Centers for Disease Control/American Academy of Periodontology were used to define periodontitis. RESULTS Education gradients were observed in relation to CP, smoking, betel quid chewing, alcohol use, and dental utilization. Education gradients in CP remained, but attenuated after adjustments for smoking, betel quid chewing, alcohol use, and dental utilization. Current smoking and current alcohol use explained 4%-38% and 6%-15% of the associations between education and CP, respectively. The education gradient in CP remained following simultaneous adjustment for all behaviors, but lost significance for 11-13 years of education. CONCLUSION Of the oral health behaviors considered, current smoking contributed the most to education inequalities in CP, explaining 4%-38% of the education differences in CP.
Self‐Sacrificial Template‐Directed Vapor‐Phase Growth of MOF Assemblies and Surface Vulcanization for Efficient Water Splitting

Direct use of metal–organic frameworks (MOFs) with robust pore structures, large surface areas, and high density of coordinatively unsaturated metal sites as electrochemical active materials is highly desirable (rather than using as templates and/or precursors for high‐temperature calcination), but this is practically hindered by the poor conductivity and low accessibility of active sites in the bulk form. Herein, a universal vapor‐phase method is reported to grow well‐aligned MOFs on conductive carbon cloth (CC) by using metal hydroxyl fluorides with diverse morphologies as self‐sacrificial templates. Specifically, by further partially on‐site generating active Co3S4 species from Co ions in the echinops‐like Co‐based MOF (EC‐MOF) through a controlled vulcanization approach, the resulting Co3S4/EC‐MOF hybrid exhibits much enhanced electrocatalytic performance toward the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), with overpotentials of 84 and 226 mV required to reach a current density of 10 mA cm−2, respectively. Density functional theory (DFT) calculations and experimental results reveal that the electron transfer between Co3S4 species and EC‐MOF can decrease the electron density of the Co d‐orbital, resulting in more electrocatalytically optimized adsorption properties for Co. This study will open up a new avenue for designing highly ordered MOF‐based surface active materials for various electrochemical energy applications.
Reduced biventricular volumes and myocardial dysfunction long-term after pediatric heart transplantation assessed by CMR.

BACKGROUND Long-term cardiac remodeling after heart transplantation (HT) in children has been insufficiently characterized. The aim of our study was to evaluate ventricular size in HT patients using cardiovascular magnetic resonance (CMR) imaging, to find underlying factors related to potentially abnormal cardiac dimensions and to study its impact on functional class and ventricular function. METHODS Seventy-five pediatric HT recipients (age 14.0 ± 4.2 years) were assessed by CMR 11.2 ± 5.4 years after HT. Right (RV) and left ventricular (LV) volumes and mass were derived from short-axis cine images and myocardial strain/strain rate was assessed using myocardial feature tracking technique. Results were compared with a healthy reference population (n=79, age 13.7 ± 3.7 years). RESULTS LV end-diastolic ventricular volumes were smaller (64 ± 12 vs. 84 ± 12 ml/m, p<0.001) while mass-to-volume ratio (0.86 ± 0.18 vs. 0.65 ± 0.11, p<0.001) and heart rate (92 ± 14 vs. 78 ± 13 bpm, p<0.001) were higher in HT patients. LV-EF was preserved (66 ± 8 vs. 64 ± 6 %, p=0.18) but RV-EF (58 ± 7 vs. 62 ± 4 %, p=0.004), LV systolic longitudinal strain (-12 ± 6 vs. -15 ± 5 %, p=0.05), diastolic strain rate (1.2 ± 0.6 vs. 1.5 ± 0.6 1/s, p=0.03) and intra- and interventricular synchrony were lower in the HT group. Smaller LV dimensions were primarily related to longer follow-up time since HT (β=-0.38, p<0.001) and were associated with worse functional class and impaired ventricular systolic and diastolic performance. CONCLUSIONS Cardiac remodeling after pediatric HT is characterized by reduced biventricular size and increased mass-to-volume ratio. These adverse changes evolve gradually and are associated with impaired functional class and ventricular dysfunction suggesting chronic maladaptive processes affecting allograft health.
CXC chemokine ligand 1 mediates adiponectin-induced angiogenesis in ovarian cancer

Objectives: Adiponectin is a cytokine secreted from adipose tissue that regulates energy homeostasis, inflammation, and cell proliferation. Obesity is associated with increased risk of various cancers, including ovarian cancer. Adipokines, including adiponectin, have been implicated as a factor linking obesity and carcinogenesis. The oncogenic role of adiponectin is not known with regard to various cancer types. We sought to determine the role of adiponectin in angiogenesis in ovarian cancer in vitro. Methods: We transfected SKOV3 cells with vascular endothelial growth factor small interfering RNA in order to identify the independent angiogenic role of adiponectin in ovarian cancer. The vascular endothelial growth factor knockdown SKOV3 cell lines were treated with adiponectin for 48 h. The cytokines involved in adiponectin-mediated angiogenesis were explored using the human angiogenesis cytokine array and were verified with the enzyme-linked immunosorbent assay. The angiogenic effect of adiponectin was evaluated using the human umbilical vein endothelial cell tube formation assay. We also investigated the effects of adiponectin treatment on the migration and invasion of SKOV3 cells. Results: The number of tubes formed by human umbilical vein endothelial cell decreased significantly after knockdown of vascular endothelial growth factor (via transfection of vascular endothelial growth factor small interfering RNA into SKOV3 cells). When these vascular endothelial growth factor knockdown SKOV3 cells were treated with adiponectin, there was an increase in the number of tubes in a tube formation assay. Following adiponectin treatment, the CXC chemokine ligand 1 secretion increased in a cytokine array. This was confirmed by both enzyme-linked immunosorbent assay and Western blot. The increased secretion of CXC chemokine ligand 1 by adiponectin occurred regardless of vascular endothelial growth factor knockdown. In addition, the induction of migration and invasion of SKOV3 cells were significantly stronger with adiponectin treatment than they were without. Conclusion: Adiponectin treatment of ovarian cancer cells induces angiogenesis via CXC chemokine ligand 1 independently of vascular endothelial growth factor. These findings suggest that adiponectin may serve as a novel therapeutic target for ovarian cancer.
