Novel Biomarkers in Patients with Chronic Kidney Disease: An Analysis of Patients Enrolled in the GCKD-Study

Background: Chronic kidney disease (CKD) and cardiovascular diseases (CVD) often occur concomitantly, and CKD is a major risk factor for cardiovascular mortality. Since some of the most commonly used biomarkers in CVD are permanently elevated in patients with CKD, novel biomarkers are warranted for clinical practice. Methods: Plasma concentrations of five cardiovascular biomarkers (soluble suppression of tumorigenicity (sST2), growth differentiation factor 15 (GDF-15), heart-type fatty acid-binding protein (H-FABP), insulin-like growth factor-binding protein 2 (IGF-BP2), and soluble urokinase plasminogen activator receptor) were analyzed by means of enzyme-linked immunosorbent assay (ELISA) in 219 patients with CKD enrolled in the German Chronic Kidney Disease (GCKD) study. Results: Except for sST2, all of the investigated biomarkers were significantly elevated in patients with CKD (2.0- to 4.4-fold increase in advanced CKD (estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m² body surface area (BSA)) and showed a significant inverse correlation with eGFR. Moreover, all but H-FABP and sST2 were additionally elevated in patients with micro- and macro-albuminuria. Conclusions: Based on our findings, sST2 appears to be the biomarker whose diagnostic performance is least affected by decreased renal function, thus suggesting potential viability in the management of patients with CVD and concomitant CKD. The predictive potential of sST2 remains to be proven in endpoint studies.
Characterisation of Microbial Community Associated with Different Disinfection Treatments in Hospital hot Water Networks

Many disinfection treatments can be adopted for controlling opportunistic pathogens in hospital water networks in order to reduce infection risk for immunocompromised patients. Each method has limits and strengths and it could determine modifications on bacterial community. The aim of our investigation was to study under real-life conditions the microbial community associated with different chemical (monochloramine, hydrogen peroxide, chlorine dioxide) and non-chemical (hyperthermia) treatments, continuously applied since many years in four hot water networks of the same hospital. Municipal cold water, untreated secondary, and treated hot water were analysed for microbiome characterization by 16S amplicon sequencing. Cold waters had a common microbial profile at genera level. The hot water bacterial profiles differed according to treatment. Our results confirm the effectiveness of disinfection strategies in our hospital for controlling potential pathogens such as Legionella, as the investigated genera containing opportunistic pathogens were absent or had relative abundances ≤1%, except for non-tuberculous mycobacteria, Sphingomonas, Ochrobactrum and Brevundimonas. Monitoring the microbial complexity of healthcare water networks through 16S amplicon sequencing is an innovative and effective approach useful for Public Health purpose in order to verify possible modifications of microbiota associated with disinfection treatments.
Asenapine in the Treatment of Bipolar Depression.

Objectives Asenapine, a potent serotonin 7 (5-HT7) receptor antagonist, was examined for efficacy as an antidepressant in depressed bipolar subjects. It was predicted that subjects with the genetic variant of the short form of the serotonin transporter (5HTTR) would be more likely to respond. Experimental Design A subset of patients participating in a randomized, placebo-controlled study of the efficacy of asenapine in bipolar I depression also underwent genetic testing for the 5HTTR. Montgomery Åsberg Depression Rating Scale (MADRS) score was ≥ 26 prior to randomization to asenapine or placebo for 8 weeks. Gene testing was performed before breaking the blind. Principal Observations Nine patients completing the study also underwent gene testing. At study end, the average MADRS improvement was -19.80 ± SD 8.59 for the 4 people randomized to asenapine and -3.80 ± 9.01 for the 5 people receiving placebo (P = 0.021, t = 2.88). Anxiety, as measured by the Hamilton Anxiety Rating Scale (HAM-A), also improved in asenapine-treated patients (-15.40 ± 6.15 vs. -2.80 ± 7.95, P = 0.023, t = 2.803). Six participants had the short form of the 5HTTR, and it is believed they influenced the significant outcome in this small sample. Conclusions While this is a very small sample, asenapine appears to have a beneficial effect on both depression and anxiety in depressed bipolar I patients compared to treatment with placebo. Due to the large fraction of subjects with the short form, the hypothesis that the SF-5HTTR might increase asenapine response could not be adequately tested.
Vitamin C regulates Schwann cell myelination by promoting DNA demethylation of pro‐myelinating genes

Ascorbic acid (vitamin C) is critical for Schwann cells to myelinate peripheral nerve axons during development and remyelination after injury. However, its exact mechanism remains elusive. Vitamin C is a dietary nutrient that was recently discovered to promote active DNA demethylation. Schwann cell myelination is characterized by global DNA demethylation in vivo and may therefore be regulated by vitamin C. We found that vitamin C induces a massive transcriptomic shift (n = 3,848 genes) in primary cultured Schwann cells while simultaneously producing a global increase in genomic 5‐hydroxymethylcytosine (5hmC), a DNA demethylation intermediate which regulates transcription. Vitamin C up‐regulates 10 pro‐myelinating genes which exhibit elevated 5hmC content in both the promoter and gene body regions of these loci following treatment. Using a mouse model of human vitamin C metabolism, we found that maternal dietary vitamin C deficiency causes peripheral nerve hypomyelination throughout early development in resulting offspring. Additionally, dietary vitamin C intake regulates the expression of myelin‐related proteins such as periaxin (PRX) and myelin basic protein (MBP) during development and remyelination after injury in mice. Taken together, these results suggest that vitamin C cooperatively promotes myelination through 1) increased DNA demethylation and transcription of pro‐myelinating genes, and 2) its known role in stabilizing collagen helices to form the basal lamina that is necessary for myelination.
A Study on the Characteristics of the Ionospheric Gradient under Geomagnetic Perturbations

The Earth’s ionosphere is greatly influenced by geomagnetic activities, especially geomagnetic storms. During a geomagnetic storm, the ionosphere suffers many perturbations, leading to a spatial gradient that are neglected during geomagnetically quiet periods. An ionospheric gradient generates potential hazards for a ground-based argumentation system (GBAS) by enlarging the errors in the delay corrections between ground monitor stations and users. To address this problem, this work investigates the characteristics of the ionospheric gradient under geomagnetic storms. Global Navigation Satellite System (GNSS) observations from the continuously operating reference station (CORS) network were used to analyze the ionospheric gradients during the geomagnetic storm on 8 September 2017. The statistical behavior of the ionospheric gradient was further discussed. Experiments show that strong geomagnetic perturbations lead to large ionospheric gradients, and the gradients also vary with the geomagnetic location.
Synthesis and Antibacterial Evaluation of Novel 1,3,4-Oxadiazole Derivatives Containing Sulfonate/Carboxylate Moiety

In order to discover new lead compounds with high antibacterial activity, a series of new derivatives were designed and synthesized by introducing a sulfonate or carboxylate moiety into the 1,3,4-oxadiazole structure. Antibacterial activity against two phytopathogens, Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas axonopodis pv. citri (Xac), was assayed in vitro. The preliminary results indicated that ten compounds including 4a-1-4a-4 and 4a-11-4a-16 had good antibacterial activity against Xoo, with EC50 values ranging from 50.1-112.5 µM, which was better than those of Bismerthiazol (253.5 µM) and Thiodiazole copper (467.4 µM). Meanwhile, 4a-1, 4a-2, 4a-3 and 4a-4 demonstrated good inhibitory effect against Xanthomonas axonopodis pv. citri with EC50 values around 95.8-155.2 µM which were better than those of bismerthiazol (274.3 µM) and thiodiazole copper (406.3 µM). In addition, in vivo protection activity of compound 4a-2 and 4a-3 against rice bacterial leaf blight was 68.6% and 62.3%, respectively, which were better than bismerthiazol (49.6%) and thiodiazole copper (42.2%). Curative activity of compound 4a-2 and 4a-3 against rice bacterial leaf blight was 62.3% and 56.0%, which were better than bismerthiazol (42.9%) and thiodiazole copper (36.1%). Through scanning electron microscopy (SEM) analysis, it was observed that compound 4a-2 caused the cell membrane of Xanthomonas oryzae pv. oryzae ruptured or deformed. The present results indicated novel derivatives of 5-phenyl sulfonate methyl 1,3,4-oxadiazole might be potential antibacterial agents.
Meta-Analysis of Spinal Anesthesia Versus General Anesthesia During Laparoscopic Total Extraperitoneal Repair of Inguinal Hernia

Supplemental Digital Content is available in the text. Objectives: To evaluate comparative outcomes of spinal anesthesia (SA) and general anesthesia (GA) during laparoscopic total extraperitoneal (TEP) repair of inguinal hernia. Methods: We systematically searched MEDLINE, EMBASE, CINAHL, CENTRAL, the World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, ISRCTN Register, and bibliographic reference lists. We applied a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits in each of the above databases. Postoperative pain assessed by visual analogue scale (VAS), individual and overall perioperative morbidity, procedure time and time taken to normal activities, were the outcome parameters. Combined overall effect sizes were calculated using fixed-effect or random-effects models. Results: We identified 5 comparative studies reporting a total of 1518 patients (2134 hernia) evaluating outcomes of laparoscopic TEP inguinal hernia repair under SA (n=1277 patients, 1877 hernia) or GA (n=241 patients, 257 hernia). SA was associated with significantly lower post-operative pain assessed by VAS at 12 hours [mean difference (MD): −0.32; 95% confidence interval (CI), −0.45 to −0.20; P<0.0001] and shorter time to normal activities (MD: −0.30; 95% CI, −0.48 to −0.11; P=0.002) compared with GA. However, it significantly increased risk of urinary retention [odds ratio (OR): 4.02; 95% CI, 1.32-12.24; P=0.01], hypotension (OR: 3.97; 95% CI, 1.57-10.39; P=0.004), headache (OR: 7.65; 95% CI, 1.98-29.48, P=0.003), and procedure time (MD: 3.82; 95% CI, 1.22-6.42; P=0.004). There was no significant difference in VAS at 24 hours (MD: 0.06; 95% CI, −0.06 to 0.17; P=0.34), seroma (OR: 1.54; 95% CI, 0.73-3.26; P=0.26), wound infection (OR: 1.03; 95% CI, 0.45-2.37; P=0.94), and vomiting (OR: 0.84; 95% CI, 0.39-1.83; P=0.66) between the 2 groups. There was a nonsignificant decrease in overall morbidity in favor of GA (OR: 1.84; 95% CI, 0.77-4.40; P=0.17) which became significant following sensitivity analysis (OR: 2.59; 95% CI, 1.23-5.49; P=0.01). Conclusions: Although TEP inguinal hernia repair under SA may reduce pain in early postoperative period, it seems to be associated with increased postoperative morbidity and longer procedure time. It may be an appropriate anesthetic modality in selected patients who are considered high risk for GA. Higher level of evidence is needed.
Nano‐Pulse Stimulation Induces Changes in the Intracellular Organelles in Rat Liver Tumors Treated In Situ

Nano‐pulse stimulation (NPS) therapy is the application of ultrafast pulses of high amplitude electrical energy to tissues to influence cell function. Unique characteristics of these pulses enable electric field penetration into the interior of cells and organelles to generate transient nanopores in both organelle and plasma membranes. The purpose of this study is to document the temporal and physical changes in intracellular organelles following NPS therapy using electron microscopy.
Associations of serum sclerostin with bone mineral density, markers of bone metabolism and thalassaemia characteristics in adult patients with transfusion-dependent beta-thalassaemia

Abstract Aim of the study: To assess serum sclerostin in transfusion-dependent beta-thalassaemia patients versus healthy controls and to examine its associations with bone mineral density, bone metabolism markers and beta thalassaemia alterations. Material and methods: Sixty-two transfusion-dependent beta-thalassaemia (TDßT) patients and 30 healthy controls were evaluated for serum sclerostin, osteocalcin, beta-cross laps, osteoprotegerin and serum level of receptor activator of nuclear factor kappa-Β ligand (sRANKL). Bone mineral density was measured at the lumbar spine and femoral neck. Thalassaemia characteristics were collected from the patients’ medical records. Results: A significantly higher sclerostin level (median 565.50 pmol/L) was observed in the transfusion-dependent beta-thalassaemia patients vs. the healthy controls (median 48.65 pmol/L, p < .001). Sclerostin showed significant associations with the Z-scores at the lumbar spine and femoral neck, osteocalcin, beta-cross laps, osteoprotegerin, sRANKL, pretransfusion haemoglobin, liver iron concentration and female gonadal state. Significantly higher levels of sclerostin were observed in splenectomized TDßT patients and in those with fragility fractures. Age, sex, body mass index, disease severity, serum ferritin, cardiac T2* and male gonadal state did not show significant associations with sclerostin. Conclusion: Sclerostin may play a role in the bone pathophysiology of beta-thalassaemia patients and could serve as a marker of severe osteoporosis. KEY MЕSSAGES Serum sclerostin is more than 10-fold higher in adult patients with transfusion-dependent beta-thalassaemia compared to healthy controls. Serum sclerostin is negatively associated with bone mineral density and the bone synthesis markers and positively with the bone resorption indices. Serum sclerostin is significantly associated with pre-transfusion haemoglobin, liver iron concentration, splenectomy status and fragility fracture events in adult patients with transfusion-dependent beta-thalassaemia. Serum sclerostin could serve as a marker of severe osteoporosis in beta-thalassaemia patients.
Trends in disease incidence and survival and their effect on mortality in Scotland: nationwide cohort study of linked hospital admission and death records 2001–2016

Objectives Identify causes and future trends underpinning Scottish mortality improvements and quantify the relative contributions of disease incidence and survival. Design Population-based study. Setting Linked secondary care and mortality records across Scotland. Participants 1 967 130 individuals born between 1905 and 1965 and resident in Scotland from 2001 to 2016. Main outcome measures Hospital admission rates and survival within 5 years postadmission for 28 diseases, stratified by sex and socioeconomic status. Results ‘Influenza and pneumonia’, ‘Symptoms and signs involving circulatory and respiratory systems’ and ‘Malignant neoplasm of respiratory and intrathoracic organs’ were the hospital diagnosis groupings associated with most excess deaths, being both common and linked to high postadmission mortality. Using disease trends, we modelled a mean mortality HR of 0.737 (95% CI 0.730 to 0.745) from one decade of birth to the next, equivalent to a life extension of ~3 years per decade. This improvement was 61% (30%–93%) accounted for by improved disease survival after hospitalisation (principally cancer) with the remainder accounted for by lowered hospitalisation incidence (principally heart disease and cancer). In contrast, deteriorations in infectious disease incidence and survival increased mortality by 9% (~3.3 months per decade). Disease-driven mortality improvements were slightly greater for men than women (due to greater falls in disease incidence), and generally similar across socioeconomic deciles. We project mortality improvements will continue over the next decade but slow by 21% because much progress in disease survival has already been achieved. Conclusion Morbidity improvements broadly explain observed mortality improvements, with progress on prevention and treatment of heart disease and cancer contributing the most. The male–female health gaps are closing, but those between socioeconomic groups are not. Slowing improvements in morbidity may explain recent stalling in improvements of UK period life expectancies. However, these could be offset if we accelerate improvements in the diseases accounting for most deaths and counteract recent deteriorations in infectious disease.

Olfactory Memory in Depression: State and Trait Differences between Bipolar and Unipolar Disorders

Background: Changes in olfactory recognition memory may constitute sensory markers in depression. Significant differences may exist between unipolar and bipolar depression. Our study compares olfactory memory between control, unipolar, and bipolar patients in depressed and euthymic states in order to identify potential markers of depression. Methods: 176 participants were recruited in 5 groups: depressed bipolar (DB), euthymic bipolar (EB), depressed unipolar (DU), euthymic unipolar (EU), and controls (HC). The participants had a standardized clinical and olfactory assessment (olfactory memory, evaluation of pleasantness, intensity, familiarity, and emotional aspect of smells). Results: DU, DB, and EU patients had a deficit in olfactory memory compared to HC. DB patients had lower capacity to recognize new odors. DB and DU patients had more limited detection of unfamiliar odors than HC. DB patients rated odors as less pleasant compared to the other groups. All groups had lower hedonic ratings than HC. DB patients had lower emotional ratings than EU patients. Conclusions: Olfactory memory is impaired in depressive states, thus constituting a state marker of depression. Impairments in olfactory memory persist after remission of bipolar depression, thus constituting a possible trait marker of bipolarity. Hedonic rating differentiates unipolar from bipolar depression. This is the first study that identifies a sensory marker differentiating between unipolar and bipolar depression.
Pulmonary tumour thrombotic microangiopathy presented as gastric signet ring cell carcinoma: A case report

Pulmonary tumour thrombotic microangiopathy (PTTM) is a rare complication of cancer characterized by widespread tumour cell emboli in small arteries and arterioles of the lung and often accompanied by microthrombi. We report a case of PTTM in a young Chinese woman that presented as gastric signet ring cell carcinoma. Although rare, PTTM should be considered in cancer patients with a rapidly progressing dyspnoea, chest computed tomography (CT) scan suggestive of pulmonary hypertension and diffuse pulmonary interstitial infiltration.
Incidence and Survival of Patients With Conjunctival Melanoma in Europe.

Importance Conjunctival melanoma (CM) is a rare ocular tumor. Estimates of incidence and survival of patients with CM are important to researchers and policy makers. Objective To estimate incidence and survival of patients with CM in Europe. Design, Setting, and Participants This population-based cohort study used data from 41 European cancer registries adhering to the RARECAREnet project. All individuals diagnosed as having malignant CM from January 1995 to December 2007 coded according to the International Classification of Diseases for Oncology, Third Edition codes C69.0 (conjunctiva) and 8720-8780 (melanoma) were included. Analysis began March 2019. Main Outcomes and Measures Trend estimates for incidence and for 5-year relative survival (the ratio of the measured survival of patients to the expected survival in the general population for the same country, age, sex, and calendar year). Crude, age-standardized, and bayesian incidence rates were calculated. Five-year relative survival was calculated by the Ederer II method with the cohort and period approach. Results A total of 724 patients 15 years or older (512 [70.7%] were 55 years or older; 366 [50.6%] were female) were analyzed with an overall crude incidence of CM (per 1 000 000 person/y) of 0.46 (95% CI, 0.42-0.49). Crude incidence was similar in men and women (0.48; 95% CI, 0.44-0.54 and 0.46; 95% CI, 0.41-0.51, respectively) and increased with age. Age-standardized incidence increased over time only in men and was the highest in Norway and the Netherlands (more than 0.70). Only 1 case in 14 years was estimated to occur in Iceland vs about 20 cases per year in large countries such as France and Germany. Percentage of 5-year survival (83.5 overall; 95% CI, 78.6-87.3) was not different between adult and elderly patients but showed large geographical disparities across European regions (range, 66-89) and improved markedly in male patients (from 76 in 1995-1998 to 86 in 2003-2007, with a difference of 10.2 [95% CI, 1.3-19.2]; P < .05) becoming similar to that of women in the last period. Conclusions and Relevance Although these data are only available through 2007 and based on registries not uniformly covering the European population, the study provides the first Europe-wide estimates of the incidence and relative survival of patients with CM using population-based data. Geographical differences in survival indicate room for outcome improvement in Southern, Northern, and Eastern European countries.
Promoting First Relationships : Implementing a Home Visiting Research Program in Two American Indian Communities

Background: Few, if any, home visiting programs for children under the age of three have been culturally adapted for American Indian reservation settings. We recently adapted one such program: Promoting First Relationships R . Objectives: To culturally adapt Promoting First Relationships R while maintaining program fidelity, we used a communitybased participatory approach to elicit input from two American Indian partners. Methods: University-based researchers, reservation-based Native project staff, and Native tribal liaisons conducted collaborative meetings, conference calls, and focus groups to adapt Promoting First Relationships R to reflect local community
