Published: August 2020

Abstract

Objectives
Although glioblastoma (GBM) is rare in the pediatric population, it is the most common cause of death among children with central nervous system neoplasms. Recent molecular profiling of these neoplasms has demonstrated distinct differences in comparison to their adult counterparts. Moreover, many pediatric GBMs occur within the context of cancer predisposition syndromes, such as constitutional mismatch repair deficiency syndrome (CMMRD). Children with CMMRD who develop GBM exhibit a high tumor mutational burden and may benefit from treatment with immune checkpoint inhibitors.

Methods
We performed next-generation sequencing and immunohistochemistry for mismatch repair proteins in our cohort of pediatric and adult GBMs to further characterize the molecular profiles of these groups.

Results
We examined a total of 11 pediatric and 11 adult GBMs. Pediatric patients had a higher number of alterations compared to their adult counterparts. They also had a higher frequency of alterations in the mismatch repair genes, which can be detected by immunohistochemistry (IHC). We also identified one pediatric patient with CMMRD syndrome.

Conclusions
Our study highlighted the distinct molecular differences between pediatric and adult GBM. We also demonstrated that pediatric patients have a higher frequency of alterations in the mismatch repair genes, which may render them susceptible to treatment with immune checkpoint inhibitors. These alterations can be detected using routine IHC and should be performed on all pediatric GBM.
Data-Driven Insights on the Effects of COVID-19 on Aesthetics: Part I (Passive Analysis)
Authors: Chandawarkar Akash , Jenny Hillary , Kim Roy 
Published: August 2020

Abstract

Background
Since COVID-19 was declared to be a worldwide pandemic and US national emergency in March (week 11), it has significantly changed aesthetic plastic surgery. As plastic surgeons now move towards reopening practices, understanding public interest in medical aesthetics will be critical to maximize efforts and resource allocation in procedures and treatments that patients want.

Objectives
In this study, the authors sought to passively query public interest in aesthetics utilizing Google Trends search data.

Methods
Google Trends was utilized to quantify relative search volumes over the past 4 years for a variety of categories: patient-related, surgery-related, injectables, breast procedures, face procedures, and body procedures. Data were deseasonalized and represented graphically. Z-scores of each time-point differing from the expected values were determined utilizing least squares regression.

Results
Of the 204 significantly anomalous search term data points in 2020, 172 (84.0%) occurred after week 11 (pandemic/national emergency declaration). Sixty percent of searches in all time-points after week 11 significantly differed, and 25/26 (96.0%) search terms experienced significant changes after week 11. There was decreased interest for 18 terms with variable recovery. Procedural nadirs for decreased search volume troughs occurred between weeks 11 and 14. Six patient-related chief complaints saw increased search interest after COVID-19, with peak interest between weeks 11 and 17.

Conclusions
This is the first study, to the authors’ knowledge, to assess real-time, national data about the impact of COVID-19 on public interest in aesthetics.

Published: August 2020

Abstract

Background
Increased body mass index (BMI) has been associated with a higher risk of severe coronavirus disease 2019 (COVID-19) infections. However, whether obesity is a risk factor for contracting COVID-19 has hardly been investigated so far.

Methods
We examined the association between BMI level and the risk of COVID-19 infection in a nationwide case-control study comprised of 3788 case patients confirmed to have COVID-19 between 24 January and 9 April 2020 and 15 152 controls matched by age and sex, who were aged 20 years or more and underwent National Health Insurance Service (NHIS) health examinations between 2015−2017, using data from the Korean NHIS with linkage to the Korea Centers for Disease Control and Prevention data. Our primary exposure of interest was BMI level, categorized into 4 groups: &lt;18.5 (underweight), 18.5–22.9 (normal weight), 23–24.9 (overweight), and ≥25 kg/m2 (obese).

Results
Of the entire 18 940 study participants, 11 755 (62.1%) were women, and the mean age of the study participants was 53.7 years (standard deviation, 13.8). In multivariable logistic regression models adjusted for sociodemographic, comorbidity, laboratory, and medication data, there was a graded association between higher BMI levels and higher risk of COVID-19 infection. Compared to normal-weight individuals, the adjusted odds ratios in the overweight and obese individuals were 1.13 (95% confidence interval [CI], 1.03–1.25) and 1.26 (95% CI, 1.15–1.39), respectively. This association was robust across age and sex subgroups.

Conclusions
Higher BMI levels were associated with a higher risk of contracting COVID-19.
Regional income disparities, monopoly and finance
Authors: Feldman Maryann , Guy Frederick , Iammarino Simona 
Published: August 2020

AbstractThe overall rise in inequality in the USA since 1980 has been matched by a rise in inequality between places; local and regional development policies aimed at reversing this polarisation have seen limited success. We propose an explanation for the spatial polarisation of prosperity and the failure of the policies to remedy it. Our explanation is based on the interaction of monopoly power, agglomeration economies in technology clusters and the power of financial sector actors over non-financial firms—all phenomena characteristic of the post-1980 economy. We review evidence for each of these elements and propose some causal relationships between them, as an outline of an ongoing research programme.
Prognostic Value of Programmed Cell Death-Ligand 1 Expression in Tumor-Infiltrating Lymphocytes and Viral Load in Peripheral Blood Mononuclear Cells for Epstein–Barr Virus–Positive Nasopharyngeal Carcinoma
Authors: Hu Bin , Sun Ming , Wang Zijin , Zheng Yanping , Cai Weifeng , Shi Helen Hsiao-Hsing , Zhuang Yanzhen , Lin Qin 
Published: August 2020

Abstract

Background
Epstein–Barr virus (EBV) infection has a role in the development and progression of nasopharyngeal carcinoma (NPC); however, it is unclear whether EBV load correlates with tumor prognosis or the need for immunotherapy. This study evaluated whether the EBV DNA concentration in peripheral blood mononuclear cells (PBMC) or programmed cell death-ligand1 (PD-L1) expression in tumor-infiltrating lymphocytes (TIL) could predict the clinical outcomes of patients with NPC.

Methods
Clinicopathological parameters of 198 patients with NPC were analyzed retrospectively from June 2012 to May 2018. Patients’ EBV loads were determined by droplet digital PCR. TIL PD-L1 was analyzed by immunohistochemistry.

Results
A log value of 1.98 log IU/mL for PBMC EBV DNA and a percentage of PD-L1 expression of 15% in TILs marked distinguishing cutoffs in NPC prognosis. The 5-year progression-free survival (PFS) rates in patients with high vs low log (PBMC EBV DNA) were 68.2% and 93.1%, respectively (P = 0.002). The 5-year PFS rates in patients with high vs low TIL PD-L1 expression were 66.3% and 33.7%, respectively (P = 0.03). The 5-year PFS rates of the high-risk group (high log [PBMC EBV DNA] and low TIL PD-L1), low-risk group (low log [PBMC EBV DNA] and high TIL PD-L1), and those in between (intermediate group) were 0%, 91.9%, and 71.4%, respectively (P &lt; 0.001).

Conclusion
Concentrations of PBMC EBV DNA and TIL PD-L1 expression can be used as prognostic markers in NPC. The combination of both an increased EBV DNA concentration and suppressed TIL PD-L1 expression is associated with metastasis or relapse.

Abstract

Background
Conventional prognostic risk factors can only partly explain the adverse clinical outcomes after ischemic stroke. We aimed to establish a set of prognostic metrics and evaluate its public health significance on the burden of adverse clinical outcomes of ischemic stroke.

Methods
All patients were from the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). We established prognostic metrics of ischemic stroke from 20 potential biomarkers in a propensity-score-matched extreme case sample (n = 146). Pathway analysis was conducted using Ingenuity Pathway Analysis. In the whole CATIS population (n = 3575), we evaluated effectiveness of these prognostic metrics and estimated their population-attributable fractions (PAFs) related to the risk of clinical outcomes. The primary outcome was a composite outcome of death or major disability (modified Rankin Scale score ≥3) at 3 months after stroke.

Results
Matrix metalloproteinase-9 (MMP-9), S100A8/A9, high-sensitivity C-reactive protein (hsCRP), and growth differentiation factor-15 (GDF-15) were selected as prognostic metrics for ischemic stroke. Pathway analysis showed significant enrichment in inflammation and atherosclerosis signaling. All 4 prognostic metrics were independently associated with poor prognosis of ischemic stroke. Compared with patients having 1 or 0 high-level prognostic metrics, those with 4 had higher risk of primary outcome (OR: 3.84, 95%CI: 2.67–5.51; PAF: 37.4%, 95%CI: 19.5%–52.9%).

Conclusion
The set of prognostic metrics, enriching in inflammation and atherosclerosis signaling, could effectively predict the prognosis at 3 months after ischemic stroke and would provide additional information for the burden of adverse clinical outcomes among patients with ischemic stroke.
A severe right-to-left intracardiac shunt after NobleStitch failure: when a device is needed
Authors: Trabattoni Daniela , Gili Sebastiano , Teruzzi Giovanni , Tamborini Gloria 
Published: August 2020

Abstract

Background
Transcatheter closure of patent foramen ovale (PFO) has been demonstrated to be superior to medical therapy in stroke prevention in selected patients. Beyond traditional permanent metallic devices, NobleStitch EL, a suture-based system, has been developed as a potential alternative.

Case summary
A 50-year-old man underwent transcatheter closure of PFO with mild interatrial septal bulging and tunnel-like morphology with a NobleStitch device. A transthoracic echocardiography performed immediately after PFO closure showed residual shunt (RS), which persisted unchanged at staged controls, due to the inability of the delivery system to capture both the septum primum and the septum secundum. A second procedure was performed with the implantation of a Figulla Flex II 27/30 mm device, with no RS detectable at control echocardiography.

Discussion
The NobleStitch device is interesting in its concept, but several pitfalls may be encountered during its deployment. Opposite to permanent metallic devices, RSs after the procedure are not expected to decrease over time and should be managed with a different approach.
ROTAVI: simultaneous left main rotablation and transcutaneous aortic valve implantation in calcified coronaries and severe aortic stenosis – a case report
Authors: Gupta Himanshu , Kaur Navjyot , Sharma Yashpaul , Barwad Parag 
Published: August 2020

Abstract

Background
There is a high incidence of calcified coronary artery disease in patients with severe valvular aortic stenosis (AS). With transcutaneous aortic valve replacement (TAVR) as one of the promising options for severe AS in high and intermediate surgical risk patients; we will encounter more and more patients who will require both complex percutaneous coronary intervention (PCI) with rotablation (RA) and TAVR. The timing of PCI in patients undergoing TAVR; however remains indecisive. Due to the complexity of procedures and the risks involved, very few cases of concomitant TAVR and coronary RA have been reported so far.

Case summary
Seventy-five years old high surgical risk female had severe AS with calcified left main (LM) distal and ostial left anterior descending (LAD) artery lesion. Successful PCI with RA to LM-LAD lesion was done followed by uneventful transfemoral TAVR in the same setting.

Discussion
This is probably one of the very few cases reported where PCI to LM with RA and TAVR was done successfully in the same setting. Since the calcified lesion was focal and left ventricular ejection fraction of the patient was normal, we went ahead with PCI without prior balloon dilatation of aortic valve (BAV) which was a deviation from the prior reported cases, where BAV was performed prior to complex PCI to improve the cardiac output. We herein discuss our case and thoughts about concomitant complex PCI and TAVR.

Published: August 2020

Abstract

Aims
Rate, incidence, risk factors, and optimal management of atrio-oesophageal fistula (AOF) after catheter ablation for atrial fibrillation (AF) remain obscure.

Methods and results
All French centres performing AF ablation were identified and surveys were sent concerning the number of procedures, eventual cases of AOF, and characteristics of such cases. Eighty-two of the 103 centres (80%) performing AF ablation in France were included, with a total of 129 286 AF ablations since 2006 (93% of the whole procedures in France). Thirty-three AOF were reported (reported rate 0.026% per procedure) with a stable reported annual incidence despite the increasing number of procedures. Sensitivity of computed tomography (CT) scan for AOF was 81%. Mortality was 60%, significantly lower in case of surgical corrective therapy (31 vs. 93%, P = 0.001).

Conclusion
The reported rate of AOF after AF ablation in this nationwide survey was 0.026%, with a stable reported annual incidence over time. A normal CT scan does not rule out the diagnosis and should be repeated in case of suspicion. Prognosis remains poor with a mortality of 60% and crucially dependant of immediate surgical correction. No clear protective strategy has been proven effective.

Abstract
Governance failures undermine efforts to achieve universal health coverage and improve health in low- and middle-income countries by decreasing efficiency and equity. Punitive measures to improve governance are largely ineffective. Social accountability strategies are perceived to enhance transparency and accountability through bottom-up approaches, but their effectiveness has not been explored comprehensively in the health systems of low- and middle-income countries in south and Southeast Asia where these strategies have been promoted. We conducted a narrative literature review to explore innovative social accountability approaches in Bangladesh, Bhutan, India, Indonesia, the Maldives, Myanmar and Nepal spanning the period 2007–August 2017, searching PubMed, Scopus and Google Scholar. To augment this, we also performed additional PubMed and Google Scholar searches (September 2017–December 2019) to identify recent papers, resulting in 38 documents (24 peer-reviewed articles and 14 grey sources), which we reviewed. Findings were analysed using framework analysis and categorized into three major themes: transparency/governance (eight), accountability (11) and community participation (five) papers. The majority of the reviewed approaches were implemented in Bangladesh, India and Nepal. The interventions differed on context (geographical to social), range (boarder reform to specific approaches), actors (public to private) and levels (community-specific to system level). The initiatives were associated with a variety of positive outcomes (e.g. improved monitoring, resource mobilization, service provision plus as a bridge between the engaged community and the health system), yet the evidence is inconclusive as to the extent that these influence health outcomes and access to health care. The review shows that there is no common blueprint which makes accountability mechanisms viable and effective; the effectiveness of these initiatives depended largely on context, capacity, information, spectrum of actor involvement, independence from power agendas and leadership. Major challenges that undermined effective implementation include lack of capacity, poor commitment and design and insufficient community participation.

Published: August 2020

SummaryThis study aimed to examine the Iranian local communities’ readiness stage to engage with childhood obesity prevention programs for late primary school children in districts 2 and 16 of Tehran as the representatives of high and low socio-economic districts, respectively. First, a Delphi approach was conducted to assess the socio-cultural necessity/appropriateness and adequacy of the community readiness model and its dimensions as a planning basis for childhood obesity prevention program(s) in Iran. Then, the community readiness interview guide’s translation, modification, content and face validity were performed. Finally, 66 interviews with key informants were conducted and scored to assess community readiness. The socio-cultural necessity/appropriateness and adequacy of community readiness model and its dimensions were confirmed by Delphi participants and two questions were added to the interview guide. Content and face validity of the interview guide were at acceptable levels. Assessment of the community readiness based on the key informants’ perspective showed that the overall mean readiness score of targeted local communities was 4.61 ± 0.54 and 4.22 ± 0.26 in high and low socio-economic districts, respectively, corresponded to ‘preplanning stage’. The highest score was 5.00 ± 0.48 correspond to the ‘preparation stage’, which belonged to girls’ schools in district 2. Small differences were found in the readiness stage of local communities by sex and socio-economic status of schools. The results highlight the need to increase community awareness, gain their support to recognize childhood obesity as a priority, address cultural misconceptions and improve the obesity prevention programs to achieve a higher level of readiness.
BK Polyomavirus–Specific CD8 T-Cell Expansion In Vitro Using 27mer Peptide Antigens for Developing Adoptive T-Cell Transfer and Vaccination
Authors: Wilhelm Maud , Kaur Amandeep , Wernli Marion , Hirsch Hans H 
Published: August 2020

Abstract

Background
BK polyomavirus (BKPyV) remains a significant cause of premature kidney transplant failure. In the absence of effective antivirals, current treatments rely on reducing immunosuppression to regain immune control over BKPyV replication. Increasing BKPyV-specific CD8 T cells correlate with clearance of BKPyV DNAemia in kidney transplant patients. We characterized a novel approach for expanding BKPyV-specific CD8 T cells in vitro using 27mer-long synthetic BKPyV peptides, different types of antigen-presenting cells, and CD4 T cells.

Methods
Langerhans cells and immature or mature monocyte-derived dendritic cells (Mo-DCs) were generated from peripheral blood mononuclear cells of healthy blood donors, pulsed with synthetic peptide pools consisting of 36 overlapping 27mers (27mP) or 180 15mers (15mP). BKPyV-specific CD8 T-cell responses were assessed by cytokine release assays using 15mP or immunodominant 9mers.

Results
BKPyV-specific CD8 T cells expanded using 27mP and required mature Mo-DCs (P = .0312) and CD4 T cells (P = .0156) for highest responses. The resulting BKPyV-specific CD8 T cells proliferated, secreted multiple cytokines including interferon γ and tumor necrosis factor α, and were functional (CD107a+/PD1–) and cytotoxic.

Conclusions
Synthetic 27mP permit expanding BKPyV-specific CD8 T-cell responses when pulsing mature Mo-DCs in presence of CD4 T cells, suggesting novel and safe approaches to vaccination and adoptive T-cell therapies for patients before and after kidney transplantation.

AbstractThis experiment evaluated the impacts of administering a bovine appeasing substance (BAS) to beef calves at weaning on their performance, physiological responses, and behavior during a 42-d preconditioning program. Eighty calves (40 heifers and 40 steers; 90% British × 10% Nellore) were weaned at 233 ± 2 d of age (day 0); ranked by sex, weaning age, and body weight (BW); and assigned to receive BAS (IRSEA Group, Quartier Salignan, France; n = 40) or placebo (diethylene glycol monoethyl ether; CON; n = 40). Treatments (5 mL) were topically applied to the nuchal skin area of each animal following dam separation. Within treatment, calves were allocated to one of eight drylot pens (four pens per treatment; pen being the experimental unit) and received a free-choice total mixed ration (TMR) from day 0 to 42, intake of which was assessed daily. Live behavior observations were conducted on days 1, 2, 4, 8, 16, and 32. Temperament was assessed and blood samples were collected via jugular venipuncture on days −21, 0, 3, 7, 14, 28, and 42. Hair samples were collected from the tail switch on days 0, 14, 28, and 42. Calves were vaccinated against bovine respiratory disease viruses on days −21 and 0. Average daily gain from day 0 to 42 did not differ between treatments (P = 0.57) but was greater (P = 0.05) in BAS vs. CON calves from day 0 to 28. Intake of TMR was greater (P = 0.05) during the first week for BAS vs. CON calves (treatment × week; P = 0.08). The mean proportion of calves feeding simultaneously and performance of social and play behaviors were greater (P ≤ 0.05) for BAS vs. CON calves. Escape attempts were greater (P &lt; 0.01) for BAS vs. CON calves on day 1 (treatment × day; P = 0.03). Exit velocity was greater (P = 0.04) for CON vs. BAS calves on day 14 and tended (P = 0.10) to be greater for CON vs. BAS calves on day 7 (treatment × day; P = 0.03). Mean plasma concentrations of haptoglobin were greater (P = 0.02) in CON vs. BAS calves. Hair cortisol concentrations were greater (P = 0.05) in CON vs. BAS calves on day 14 (treatment × day; P = 0.03). Mean serum concentrations of antibodies against bovine viral diarrhea virus were greater (P = 0.02) in BAS vs. CON calves. Collectively, BAS administration to beef calves at weaning alleviated stress-induced physiological reactions, improved temperament evaluated via chute exit velocity, enhanced humoral immunity acquired from vaccination, and appeared to have accelerated adaptation to novel management scheme and environment.
