AbstractThe steadily increasing epidemic of obesity continues at alarming rates, is an important public health problem, and expression changes of S100A16 and 11 β-hydroxysteroid dehydrogenase type 1(11β-HSD1) is attributable to the adipocyte differentiation. In our previous study, we found that 11β-HSD1 protein expression increased in S100A16-overexpressed 3T3-L1 cell model. In order to further investigate the relationship between S100A16 and 11β-HSD1, and the molecular mechanisms of S100A16-induced adipogenesis, we constructed S100A16 transgenic and knockout mouse, and S100A16-overexpressed 3T3-L1 preadipocyte cell. Using S100A16 transgenic (S100A16Tg/+) mice fed with normal fat diet (NFD) and high fat diet (HFD) diet model, we evaluated the effect of S100A16 on adipogenesis, expression of 11β-HSD1, and RNA sequencing and quantification of gene expression. Using the 3T3-L1 cell model, we examined the effect of S100A16 and 11β-HSD1 on pre-adipocyte differentiation, and cell signaling events of 11β-HSD1 overexpression induced by S100A16. We found that when compared with C57BL/6 mice, overexpression of S100A16 under the condition of HFD increased lipid content in WAT and fat infiltration in hepatocytes, 11β-HSD1 protein expression increased along with S100A16. Elevated S100A16 and 11β-HSD1 expression promoted adipogenesis in 3T3-L1 cells. Overexpression of S100A16 inhibited the degradation of 11β-HSD1. We conclude that S100A16-induced adipogenesis is associated with up-regulation of 11β-HSD1.
LncRNA LUCAT1 facilitates tumorigenesis and metastasis of triple-negative breast cancer through modulating miR-5702
Authors: Mou Exian , Wang Hao 
Published: August 2019

Abstract
Triple-negative breast cancer (TNBC) is a subtype of aggressive breast cancer with high recurrence and poor survival. Emerging evidence has indicated that long non-coding RNAs (lncRNAs) play pivotal roles in the development and progression of multiple cancers. Although there are substantial studies revealing that lung cancer-associated transcript 1 (LUCAT1) functions as a tumor promotor in various human cancers, the molecular mechanism of LUCAT1 in TNBC remains largely to be explored. In our study, we identified that LUCAT1 expression was dramatically enhanced in TNBC samples and cells. High LUCAT1 expression was strongly associated with advanced stages and poor prognosis of TNBC. LUCAT1 contributed to TNBC development through accelerating cell proliferation, cell cycle progression and metastasis as well as attenuating cell apoptosis. Moreover, miR-5702 was proved to directly bind to LUCAT1 and be negatively modulated by LUCAT1. Knockdown of miR-5702 reversed the suppressing influences of LUCAT1 depletion on TNBC progression. In conclusion, it was the first investigation to shed light on the significant function and underlying regulatory mechanism of LUCAT1 in TNBC tumorigenesis. We validated that LUCAT1 induced tumorigenesis and metastasis of TNBC via miR-5702, which provided clues for improving the treatment of TNBC.

Abstract
Plasma levels of chemerin, an adipocytokine produced from the adipose tissues and liver, are associated with metabolic syndrome and coronary artery disease (CAD). Chemerin and its analog, chemerin-9, are known to bind to their receptor, ChemR23. However, whether chemerin and chemerin-9 affect atherogenesis remains to be elucidated. We investigated the expression of chemerin and ChemR23 in human coronary arteries and cultured human vascular cells. The effects of chemerin and chemerin-9 on atheroprone phenomena were assessed in human THP1 monocytes, human umbilical vein endothelial cells (HUVECs), and human aortic smooth muscle cells (HASMCs) and aortic lesions in Apoe−/− mice. In patients with CAD, a small amount of ChemR23, but not chemerin, was expressed within atheromatous plaques in coronary arteries. Chemerin and ChemR23 were expressed at high levels in THP1 monocytes, THP1-derived macrophages, and HUVECs; however, their expression in HASMCs was weak. Chemerin and chemerin-9 significantly suppressed the tumor necrosis factor-α (TNF-α)-induced mRNA expression of adhesion and pro-inflammatory molecules in HUVECs. Chemerin and chemerin-9 significantly attenuated the TNF-α-induced adhesion of THP1 monocytes to HUVECs and macrophage inflammatory phenotype. Chemerin and chemerin-9 suppressed oxidized low-density lipoprotein (oxLDL)-induced macrophage foam cell formation associated with down-regulation of CD36 and up-regulation of ATP-binding cassette transporter A1 (ABCA1). In HASMCs, chemerin and chemerin-9 significantly suppressed migration and proliferation without inducing apoptosis. In the Apoe−/− mice, a 4-week infusion of chemerin-9 significantly decreased the areas of aortic atherosclerotic lesions by reducing intraplaque macrophage and SMC contents. Our results indicate that chemerin-9 prevents atherosclerosis. Therefore, the development of chemerin analogs/ChemR23 agonists may serve as a novel therapeutic target for atherosclerotic diseases.
Medikamentöse Langzeittherapien zur Prognoseverbesserung bei Leberzirrhose und zur Vermeidung von Komplikationen der portalen Hypertension
Authors: Holstege Axel 
Published: August 2019

ZusammenfassungDie portale Hypertension bei Patienten mit Leberzirrhose kann nicht nur durch interventionelle (TIPS: transjugulärer portosystemischer Stent-Shunt) oder operative Shuntanlagen, sondern auch medikamentös beeinflusst werden. Zahlreiche Studien beschäftigten sich mit der Frage, ob diese Substanzen bei dauerhafter Gabe zu einer Prognoseverbesserung bei Patienten mit Leberzirrhose führen können. Nicht selektive Betablocker (NSBB), Statine, Antibiotika, Enoxaparin und Albumin haben viele Angriffspunkte in der Pathogenese der portalen Hypertension oder bei Dekompensation der Leberzirrhose, sodass sie grundsätzlich als Kandidaten für eine Langzeittherapie infrage kommen. Während es für NSBB, Antibiotika und Albumin klare Indikationen in der Versorgung von Patienten mit dekompensierter Leberzirrhose gibt, ist dies weniger geklärt für den Einsatz von Statinen oder Antikoagulanzien. Neuere Untersuchungen ergaben widersprüchliche Ergebnisse, wenn der primäre Endpunkt einer Studie die Prognoseverbesserung oder die Vermeidung einer Dekompensation der Zirrhose durch eine dauerhafte medikamentöse Therapie war. Zum jetzigen Zeitpunkt ergibt sich aufgrund der aktuellen Studienlage keine Veranlassung, das bisherige, in Leitlinien abgesicherte Vorgehen im täglichen Alltag zu ändern. Diese Übersicht gibt einen Überblick zum Einsatz von NSBB, Antibiotika, Statinen, Antikoagulanzien und Albumin bei Komplikationen der portalen Hypertension insbesondere im Hinblick auf ihren dauerhaften Einsatz zur Verbesserung des Überlebens von Patienten mit Leberzirrhose.
Variability in exercise physiology: Can capturing intra‐individual variation help better understand true inter‐individual responses?

Published: August 2019

AbstractExploring individual responses to exercise training is a growing area of interest. Understanding reasons behind true observed inter‐individual responses may help personalise exercise training to maximise the benefits received. While numerous factors have been explored, an often underappreciated consideration in the sport and exercise science field is the influence intra‐individual variation, both in a single measurement and in response to an intervention, may have on training outcomes. Several study designs and statistical approaches are available to incorporate intra‐individual variation into interventions and accordingly provide information on whether ‘true’ inter‐individual responses are present or if they are an artefact of intra‐individual variation. However, such approaches are sparingly applied. Moreover, intra‐individual variation may also be important when true inter‐individual response differences are present. In this perspective piece, the concept of intra‐individual variation is described before briefly summarising study designs and statistical practices to account for intra‐individual variation. We then outline two examples of physiological practices (stratified randomisation and prescribing exercise programmes upon training parameters) to demonstrate why sport and exercise scientists should acknowledge intra‐individual variation prior to the implementation of an intervention, which potentially offers an additional explanation behind observed true inter‐individual responses to training. Repeated testing pre‐implementation of exercise training would conceptually provide more confident estimates of training parameters, which if utilised in a study design will help attenuate biases that may dictate inter‐individual differences. Moreover, the incorporation of intra‐individual differences will facilitate insights into alternative factors that may predict and/or explain true observed individual responses to an exercise training programme.

AbstractBackgroundMeningitis is endemic in Niger. Haemophilus influenzae type b (Hib) vaccine and the 13-valent pneumococcal conjugate vaccine (PCV13) were introduced in 2008 and 2014, respectively. Vaccination campaign against Neisseria meningitidis serogroup A was carried out in 2010–2011. We evaluated changes in pathogen distribution using data from hospital-based surveillance in Niger from 2010 through 2016.MethodsCerebrospinal fluid (CSF) specimens from children <5 years old with suspected meningitis were tested to detect vaccine-preventable bacterial pathogens. Confirmatory identification and serotyping/grouping of Streptococcus pneumoniae, N. meningitidis, and H. influenzae were done. Antimicrobial susceptibility testing and whole genome sequencing were performed on S. pneumoniae isolates.ResultsThe surveillance included 2580 patients with suspected meningitis, of whom 80.8% (2085/2580) had CSF collected. Bacterial meningitis was confirmed in 273 patients: 48% (131/273) was N. meningitidis, 45% (123/273) S. pneumoniae, and 7% (19/273) H. influenzae. Streptococcus pneumoniae meningitis decreased from 34 in 2014, to 16 in 2016. PCV13 serotypes made up 88% (7/8) of S. pneumoniae meningitis prevaccination and 20% (5/20) postvaccination. Neisseria meningitidis serogroup C (NmC) was responsible for 59% (10/17) of serogrouped N. meningitidis meningitis. Hib caused 67% (2/3) of the H. influenzae meningitis isolates serotyped. Penicillin resistance was found in 16% (4/25) of S. pneumoniae isolates. Sequence type 217 was the most common lineage among S. pneumoniae isolates.ConclusionsNeisseria meningitidis and S. pneumoniae remain important causes of meningitis in children in Niger. The decline in the numbers of S. pneumoniae meningitis post-PCV13 is encouraging and should continue to be monitored. NmC is the predominant serogroup causing N. meningitidis meningitis.

Abstract

Background
The safe removal of personal protective equipment (PPE) can limit transmission of serious communicable diseases, but this process poses challenges to healthcare workers (HCWs).

Methods
We observed 41 HCWs across 4 Ebola treatment centers in Georgia doffing PPE for simulated patients with serious communicable diseases. Using human factors methodologies, we obtained the details, sequences, and durations of doffing steps; identified the ways each step can fail (failure modes [FMs]); quantified the riskiness of FMs; and characterized the workload of doffing steps.

Results
Eight doffing steps were common to all hospitals—removal of boot covers, gloves (outer and inner pairs), the outermost garment, the powered air purifying respirator (PAPR) hood, and the PAPR helmet assembly; repeated hand hygiene (eg, with hand sanitizer); and a final handwashing with soap and water. Across hospitals, we identified 256 FMs during the common doffing steps, 61 of which comprised 19 common FMs. Most of these common FMs were above average in their riskiness at each hospital. At all hospitals, hand hygiene, removal of the outermost garment, and removal of boot covers were above average in their overall riskiness. Measurements of workload revealed that doffing steps were often mentally demanding, and this facet of workload correlated most strongly with the effortfulness of a doffing step.

Conclusions
We systematically identified common points of concern in protocols for doffing high-level PPE. Addressing FMs related to hand hygiene and the removal of the outermost garment, boot covers, and PAPR hood could improve HCW safety when doffing high-level PPE.
We identified ways that doffing protocols for high-level personal protective equipment may fail to protect healthcare workers. Hand hygiene, removing the outermost garment, boot covers, and respirator hood harbored the greatest risk and failed in similar ways across different hospitals.

Abstract
Although it is common to analyze efficacy and safety separately in clinical trials, this could yield a misleading study conclusion if an increase in efficacy is accompanied by a decrease in safety. A risk-benefit analysis is a systematic approach to examine safety and efficacy jointly. Both the “rank-based” and “partial-credit” methods described in this paper allow researchers to create a single, composite outcome incorporating efficacy, safety, and other factors. The first approach compares the distribution of rankings between arms. In the second approach, a score can be assigned to each outcome category, considering its severity and comparing the mean or median scores of arms. The methods were applied to the A5279/Brief Rifapentine-Isoniazid Efficacy for TB Prevention study, and design considerations for future clinical trials are discussed, including the challenge of arriving at a consensus on rankings/scorings. If well designed, a risk-benefit analysis may allow for a superiority comparison and, therefore, avoid setting a noninferiority margin.

Establishment Closures in Germany: The Motherhood Penalty at Job Search Durations
Authors: Frodermann Corinna , Müller Dana 
Published: August 2019

AbstractThis study contributes to the research on motherhood penalties by investigating based on German longitudinal register data whether mothers take longer to search for a job than childless women. We develop a unique research design to test the theory of statistical discrimination as well as the theory of status-based discrimination. We use establishment closures as a starting point that creates equal conditions for all previously employed women. Following a subsequent coarsened exact matching approach, we investigate the job search length of almost 3,000 comparable full-time working childless women and mothers from almost 700 establishments by applying event history techniques. Even after extensive robustness checks that back up the main findings, we can show that mothers have lower transition rates to re-employment than childless women. When including additional information, such as higher age of the youngest child or shorter parental leave durations, both of which serve as indicators of higher labour market attachment, we find reduced differences and buffering effects on the motherhood penalty.
Gtf2i and Gtf2ird1 mutation do not account for the full phenotypic effect of the Williams syndrome critical region in mouse models
Authors: Kopp Nathan , McCullough Katherine , Maloney Susan E , Dougherty Joseph D 
Published: August 2019

Abstract
Williams syndrome (WS) is a neurodevelopmental disorder caused by a 1.5–1.8 Mbp deletion on chromosome 7q11.23, affecting the copy number of 26–28 genes. Phenotypes of WS include cardiovascular problems, craniofacial dysmorphology, deficits in visual–spatial cognition and a characteristic hypersocial personality. There are still no genes in the region that have been consistently linked to the cognitive and behavioral phenotypes, although human studies and mouse models have led to the current hypothesis that the general transcription factor 2 I family of genes, GTF2I and GTF2IRD1, are responsible. Here we test the hypothesis that these two transcription factors are sufficient to reproduce the phenotypes that are caused by deletion of the WS critical region (WSCR). We compare a new mouse model with loss of function mutations in both Gtf2i and Gtf2ird1 to an established mouse model lacking the complete WSCR. We show that the complete deletion (CD) model has deficits across several behavioral domains including social communication, motor functioning and conditioned fear that are not explained by loss of function mutations in Gtf2i and Gtf2ird1. Furthermore, transcriptome profiling of the hippocampus shows changes in synaptic genes in the CD model that are not seen in the double mutants. Thus, we have thoroughly defined a set of molecular and behavioral consequences of complete WSCR deletion and shown that genes or combinations of genes beyond Gtf2i and Gtf2ird1 are necessary to produce these phenotypic effects.
Gross national income and antibiotic resistance in invasive isolates: analysis of the top-ranked antibiotic-resistant bacteria on the 2017 WHO priority list

Published: August 2019

Abstract

Objectives
To assess the association between country income status and national prevalence of invasive infections caused by the top-ranked bacteria on the WHO priority list: carbapenem-resistant (CR) Acinetobacter spp., Klebsiella spp. and Pseudomonas aeruginosa; third-generation cephalosporin-resistant (3GCR) Escherichia coli and Klebsiella spp.; and MRSA and vancomycin-resistant Enterococcus faecium (VR E. faecium).

Methods
Active surveillance systems providing yearly prevalence data from 2012 onwards for the selected bacteria were included. The gross national income (GNI) per capita was used as the indicator for income status of each country and was log transformed to account for non-linearity. The association between antibiotic prevalence data and GNI per capita was investigated individually for each bacterium through linear regression.

Results
Surveillance data were available from 67 countries: 38 (57%) were high income, 16 (24%) upper-middle income, 11 (16%) lower-middle income and two (3%) low income countries. The regression showed significant inverse association (P<0.0001) between resistance prevalence of invasive infections and GNI per capita. The highest rate of increase per unit decrease in log GNI per capita was observed in 3GCR Klebsiella spp. (22.5%, 95% CI 18.2%–26.7%), CR Acinetobacter spp. (19.2% 95% CI 11.3%–27.1%) and 3GCR E. coli (15.3%, 95% CI 11.6%–19.1%). The rate of increase per unit decrease in log GNI per capita was lower in MRSA (9.5%, 95% CI 5.2%–13.7%).

Conclusions
The prevalence of invasive infections caused by the WHO top-ranked antibiotic-resistant bacteria is inversely associated with GNI per capita at the global level. Public health interventions designed to limit the burden of antimicrobial resistance should also consider determinants of poverty and inequality, especially in lower-middle income and low income countries.
Pulmonary Coccidioidomycosis Mimicking Aspergillosis Fungus Ball
Authors: Sathirareuangchai Sakda , Whelen A Christian 
Published: August 2019

AbstractThe genus Coccidioides is composed of C. immitis and C. posadasii. Both can cause coccidioidomycosis and are geographically restricted to certain areas of endemicity. The histopathologic features in pulmonary coccidioidomycosis include necrotizing granulomatous inflammation and the presence of spherules, which is considered to be a key diagnostic finding. Cavitary lung disease containing a fungal ball with branching septate hyphae is an unusual funding in pulmonary coccidioidomycosis but is typical for aspergillosis. We present a case of 42 year old man who underwent wedge resection of the lung for a persistent cavitary lesion. The microscopic examination shows a fungal ball composed of acute-angle branching septate hyphae, consistent with a diagnosis of aspergillosis. However, cultures and molecular testing by DNA sequencing of the 28S ribosomal DNA gene confirmed the identification of C. posadasii. This finding highlights the importance of exposure history and organism identification by either conventional cultivation or molecular testing in rendering an accurate diagnosis.

Abstract

Background
American tegumentary leishmaniasis (ATL) is a neglected disease with wide territorial distribution. Knowledge is scarce in children and adolescents. This study aims to compare the clinical features and response to antimony treatment in pediatric and adult patients with cutaneous leishmaniasis.

Methods
A retrospective cohort study was performed with 659 patients who attended a reference centre in Rio de Janeiro, Brazil, from 2000 to 2015. The pediatric cohort consisted of 131 (20%) patients and the adult cohort consisted of 528 (80%) patients.

Results
The epidemiological profile, antimony therapeutic response and incidence of adverse events (AE) were different in the pediatric cohort compared with the adult cohort. Mucosal form was less frequent in the pediatric cohort (RR:0.49, p=0.011). Lesions in the head, neck and trunk were more frequent in the pediatric cohort (RR:1.49, p=0.043). The effectiveness of antimony treatment was superior in the pediatric cohort (88.3% vs 76.6%) with a shorter healing time (RR:0.49, p=0.009). Pediatric patients had lower proportions of moderate to severe AE compared with adults (RR:0.45, p=0.027). Clinical AE predominated in the adult cohort (RR:0.40, p=0.000) and laboratory AE in the pediatric cohort (RR:1.50, p=0.023).

Conclusions
This study adds to the body of knowledge on differences that exist between different age groups in ATL.
