Laboratory Test to Evaluate the Resistance of Cementitious Materials to Biodeterioration in Sewer Network Conditions

The biodeterioration of cementitious materials in sewer networks has become a major economic, ecological, and public health issue. Establishing a suitable standardized test is essential if sustainable construction materials are to be developed and qualified for sewerage environments. Since purely chemical tests are proven to not be representative of the actual deterioration phenomena in real sewer conditions, a biological test–named the Biogenic Acid Concrete (BAC) test–was developed at the University of Toulouse to reproduce the biological reactions involved in the process of concrete biodeterioration in sewers. The test consists in trickling a solution containing a safe reduced sulfur source onto the surface of cementitious substrates previously covered with a high diversity microbial consortium. In these conditions, a sulfur-oxidizing metabolism naturally develops in the biofilm and leads to the production of biogenic sulfuric acid on the surface of the material. The representativeness of the test in terms of deterioration mechanisms has been validated in previous studies. A wide range of cementitious materials have been exposed to the biodeterioration test during half a decade. On the basis of this large database and the expertise gained, the purpose of this paper is (i) to propose a simple and robust performance criterion for the test (standardized leached calcium as a function of sulfate produced by the biofilm), and (ii) to demonstrate the repeatability, reproducibility, and discriminability of the test method. In only a 3-month period, the test was able to highlight the differences in the performances of common cement-based materials (CEM I, CEM III, and CEM V) and special calcium aluminate cement (CAC) binders with different nature of aggregates (natural silica and synthetic calcium aluminate). The proposed performance indicator (relative standardized leached calcium) allowed the materials to be classified according to their resistance to biogenic acid attack in sewer conditions. The repeatability of the test was confirmed using three different specimens of the same material within the same experiment and the reproducibility of the results was demonstrated by standardizing the results using a reference material from 5 different test campaigns. Furthermore, developing post-testing processing and calculation methods constituted a first step toward a standardized test protocol.
Effect of Doping Ions on Electrochemical Properties of LiFePO4 Cathode

Lithium iron phosphate (LiFePO4) cathode materials containing different low concentration ion dopants (Mg2+, Al3+, Zr4+, and Nb5+) were prepared by a solid-state reaction method in an inert atmosphere. The effects of the doping ions on the properties of as-synthesized cathode materials were investigated. XRD results indicate that the ion dopants do not affect the structure of the materials. The galvanostatically charge and discharge tests show that ion dopants can considerably improve the electrochemical performance of the materials, especially large current discharge behaviors. LiFePO4 samples doped with Nb5+ have an initiate capacity of 146.8 mAh•g-1 at 0.1C. Further cycle performance measurements reveal the sample doped with Nb5+ shows the best cycleability. The results also verify that LiFePO4 doped with ions of suited radius and higher valence shows better electrochemical characters.
Leadership Development Programs for Radiology Residents: A Literature Review

Purpose: Leadership development has become increasingly important in medical education, including postgraduate training in the specialty of radiology. Since leadership skills may be acquired, there is a need to establish leadership education in radiology residency training. However, there is a paucity of literature examining the design, delivery, and evaluation of such programs. The purpose of this study is to collate and characterize leadership training programs across postgraduate radiology residencies found in the literature. Methods: A scoping review was conducted. Relevant articles were identified through a search of Ovid MEDLINE, Ovid EMBASE, Cochrane, PubMed, Scopus, and ERIC databases from inception until June 22, 2020. English-language studies characterizing leadership training programs offered during postgraduate radiology residency were included. A search of the grey literature was completed via a web-based search for target programs within North America. Results: The literature search yielded 1168 citations, with 6 studies meeting inclusion criteria. Four studies were prospective case series and two were retrospective. There was heterogeneity regarding program structure, content, teaching methodology, and evaluation design. All programs were located in the United States. Outcome metrics and success of the programs was variably reported, with a mix of online and in person feedback used. The grey literature search revealed 3 American-based programs specifically catered to radiology residents, and none within Canada. Conclusion: The review highlighted a paucity of published literature describing leadership development efforts within radiology residency programs. The heterogeneity of programs highlighted the need for guidance from regulatory bodies regarding delivery of leadership curricula.
Effects of β-Cryptoxanthin on Improvement in Osteoporosis Risk: A Systematic Review and Meta-Analysis of Observational Studies

Many studies have analyzed the effects of β-cryptoxanthin (BCX) on osteoporosis and bone health. This systematic review and meta-analysis aimed at providing quantitative evidence for the effects of BCX on osteoporosis. Publications were selected and retrieved from three databases and carefully screened to evaluate their eligibility. Data from the final 15 eligible studies were extracted and uniformly summarized. Among the 15 studies, seven including 100,496 individuals provided information for the meta-analysis. A random effects model was applied to integrate the odds ratio (OR) to compare the risk of osteoporosis and osteoporosis-related complications between the groups with high and low intake of BCX. A high intake of BCX was significantly correlated with a reduced risk of osteoporosis (OR = 0.79, 95% confidence interval (CI) 0.70–0.90, p = 0.0002). The results remained significant when patients were stratified into male and female subgroups as well as Western and Asian cohorts. A high intake of BCX was also negatively associated with the incidence of hip fracture (OR = 0.71, 95% CI 0.54–0.94, p = 0.02). The results indicate that BCX intake potentially reduces the risk of osteoporosis and hip fracture. Further longitudinal studies are needed to validate the causality of current findings.
Diagnostic value of a comprehensive, urothelial carcinoma–specific next‐generation sequencing panel in urine cytology and bladder tumor specimens

Urine cytology can reliably diagnose high‐grade urothelial carcinoma (HGUC) but not low‐grade urothelial carcinoma (LGUC), and a more sensitive test is needed. Previously, a pilot study highlighted the possible diagnostic utility of next‐generation sequencing (NGS) in identifying both LGUC and HGUC in urine cytology specimens.
Curcumin suppresses the stemness of non‐small cell lung cancer cells via promoting the nuclear‐cytoplasm translocation of TAZ

Curcumin has been shown to suppress the progression of lung cancer, however, the underlying mechanisms are largely unknown. Here, we aimed to investigate the effects of curcumin on the stemness of non‐small cell lung cancer (NSCLC) cells. We found that curcumin reduced the sphere formation ability at the concentrations without affecting the cell viability of NSCLC cells and normal pulmonary epithelial cells, which is evident by the decrease of sphere size and number. In addition, curcumin decreased ALDH activity and the expression of stemness markers (CD133, EpCAM, Oct4). RNA sequencing analysis revealed that the Hippo pathway was mostly enriched in cells with curcumin treatment. Indeed, the expression of cancer stem cell markers was significantly decreased by curcumin treatment by analyzing the RNA sequencing data. Gene set enrichment analysis (GSEA) showed that curcumin negatively regulated the cancer stem cell function and positively modulated cancer stem cell differentiation ability. Furthermore, curcumin enhanced the cisplatin sensitivity of NSCLC cells. Mechanistically, it was found that curcumin promoted the nuclear‐cytoplasm translocation of TAZ, but not YAP, the critical effectors of Hippo pathway. In addition, curcumin destabilzed TAZ protein stability and promoted TAZ protein degradation in lung cancer cells, which is dependent on the proteasome degradation system, not by autophagy lysosome degradation system. Overexpression of TAZ rescued the inhibition of curcumin on the stemness of lung cancer cells. Thus, our results suggest that curcumin can attenuate the stemness of lung cancer cells through promoting TAZ protein degradation and thus activating Hippo pathway.
Are the factors associated with overweight/general obesity and abdominal obesity different depending on menopausal status?

Rapid modernization in China has impacted the daily lives and health of women, including a rise in obesity. However, little is known about the impact of menopausal status, behavior, and psychosocial factors on the risk of obesity for rural women in China. The aim of this study is to identify risk factors, including demographic information (education, family history of T2DM, menopausal status), obesity-related behavior, and psychosocial factors associated with overweight/general obesity and abdominal obesity. In a cross-sectional study design, participants had their weight, height, and waist circumference measured and completed questionnaires regarding family demographics, obesity-related health behaviors (physical activity, diet, sleep), and psychosocial information (stress, social support, and self-efficacy related to physical activity and healthy diet). A total of 646 women were included in this study; 46.6% were overweight/generally obese, and 48% had abdominal obesity. Postmenopausal women had a higher prevalence of general and central obesity. Regular physical activity decreased the risk for overweight/general obesity and abdominal obesity (OR = .41 and .31, respectively, p = .04) in premenopausal women. Postmenopausal women who had not breastfed their infants and reported moderate/high-stress had a higher risk for overweight/general obesity (OR = 3.93, and 2, respectively) and those who reported less than 6 hours of sleep per day increased their risk for abdominal obesity (OR = 2.08). Different factors associated with obesity were found in Chinese women, depending on menopausal status. Future studies should examine the impact of menopause on a woman’s risk for obesity, as well as develop tailored interventions to improve health, well-being and reduce the risk of obesity.
Opportunity Costs or Not? Validating the Short Gambling Harm Screen against a Set of “Unimpeachable” Negative Impacts

Assessing the harmful consequences of gambling is an area of active investigation. One measure intended to capture gambling-related harm is the 10-item short gambling harm screen (SGHS). Although good psychometric properties have been reported, it has been suggested that the screen’s less severe probes may not represent genuinely harmful consequences, but rather may reflect rational opportunity costs. Consequently, it has been argued that the screen may lead to overestimation of the extent of gambling-related harm in the population. The current study sought to examine the psychometric performance of three less severe suspect items in the SGHS. Associations between each of these items and a specially constructed scale of relatively severe “unimpeachable” gambling harms were calculated from archival data from 5551 Australian and New Zealand gamblers. All three suspect items, both individually and upon aggregation, predicted greater endorsement of “unimpeachable” harms, and indicated the presence of gambling problems. Moreover, the SGHS as a whole is highly correlated with “unimpeachable” gambling harms. Including suspect items in the SGHS was found to improve predictions of low- and moderate-risk gambling status, but slightly decreased predictions of severe gambling problems. The results are inconsistent with the notion that SGHS harm probes capture either inconsequential consequences or opportunity costs. They confirm prior findings that harm symptomatology is unidimensional, and that the report of multiple more prevalent, but less severe, harms serves as an effective indicator of the spectrum of experienced harm.
Using the CES-D-7 as a Screening Instrument to Detect Major Depression among the Inmate Population

Major depression is one of the most prevalent mental health problems in the penitentiary context and has been related to different undesirable outcomes. The aim of the current research was to evaluate the utility of screening tools for major depression brief assessment in the jail context. We interviewed 203 male inmates and complimented the MCMI-III, the SCL-90-R, and the CES-D-7 self-informed scales. Major depression syndrome and disorder were determined based on MCMI-III criteria and the capability of SCL-90-R and CES-D-7 to identify true positives and true negatives when tested. SCL-90-R and CES-D-7 showed good sensitivity for major depression syndrome and disorder. The specificity of SCL-90-R was poor in all cases, but CES-D-7 showed good specificity depending on the cut-off score. Rigorous interviews are needed for better evaluation of major depression in jails, but screening tools like CES-D-7 are useful for rapid assessment considering the work overload of penitentiary psychologists.
Structural and optical properties of electrochemically deposited ZnO films in electrolyte containing Al2(SO4)3

The present work concerns the electrochemical deposition of aluminium doped ZnO nanostructured thin films on SnO2:F covered glass substrates. Doped with Al nanostructured ZnO (ZnO:Al) films are obtained by an electrochemical process using a three-electrode potentiostatic system with a saturated calomel electrode as reference electrode, in aqueous solution containing ZnCl2, KCl and Al2(SO4)3. The influence of the deposition parameters on the structural properties of the obtained ZnO:Al layers is investigated by Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and Atomic Force Microscopy (AFM). Energy Dispersive X-ray Analysis (EDAX) is applied for measurement of the Al content in the films. The SEM micrographs and AFM pictures show that the ZnO:Al films consist of nanograins with a shape of walls. The XRD spectra demonstrate (100), (002), (101), (110) and (103) the characteristic reflexes of the ZnO. Influence of the Al concentration on the IR reflectance spectra and haze ratio of ZnO:Al thin films are presented and discussed.
Personalized connectivity‐guided DLPFC‐TMS for depression: Advancing computational feasibility, precision and reproducibility

Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) is an established treatment for refractory depression, however, therapeutic outcomes vary. Mounting evidence suggests that clinical response relates to functional connectivity with the subgenual cingulate cortex (SGC) at the precise DLPFC stimulation site. Critically, SGC‐related network architecture shows considerable interindividual variation across the spatial extent of the DLPFC, indicating that connectivity‐based target personalization could potentially be necessary to improve treatment outcomes. However, to date accurate personalization has not appeared feasible, with recent work indicating that the intraindividual reproducibility of optimal targets is limited to 3.5 cm. Here we developed reliable and accurate methodologies to compute individualized connectivity‐guided stimulation targets. In resting‐state functional MRI scans acquired across 1,000 healthy adults, we demonstrate that, using this approach, personalized targets can be reliably and robustly pinpointed, with a median accuracy of ~2 mm between scans repeated across separate days. These targets remained highly stable, even after 1 year, with a median intraindividual distance between coordinates of only 2.7 mm. Interindividual spatial variation in personalized targets exceeded intraindividual variation by a factor of up to 6.85, suggesting that personalized targets did not trivially converge to a group‐average site. Moreover, personalized targets were heritable, suggesting that connectivity‐guided rTMS personalization is stable over time and under genetic control. This computational framework provides capacity for personalized connectivity‐guided TMS targets to be robustly computed with high precision and has the flexibly to advance research in other basic research and clinical applications.
What Is Known about Community Pharmacy-Based Take-Home Naloxone Programs and Program Interventions? A Scoping Review

A variety of new sources describing community pharmacy-based take-home naloxone (THN) programs have emerged recently in the literature. There is a need to define the types of take-home naloxone programs being offered to support future research designs in implementing and evaluating standardized programs that fill pharmacist and patient knowledge gaps and lift current barriers for optimal community pharmacy naloxone provision. The objective of this paper is to summarize the literature on community pharmacy-based THN programs, including specific program interventions used to increase naloxone dispensing, naloxone availability and dispensing patterns, facilitators and barriers for the THN programs, and knowledge gaps. Online databases such as PubMed, EMBASE, Scopus, and International Pharmaceutical Abstracts (IPA) and a search of the grey literature were used to identify eligible sources. Sources were screened by two reviewers for eligibility in COVIDENCE software. Both reviewers compared screening results and resolved conflicts through discussion. A data extraction form for all identified full texts was completed by both reviewers and results were compiled through reviewer discussion. Fifty-two sources met the eligibility criteria. The top three barriers identified were: cost/coverage of naloxone, stigma, and education/training for pharmacists. THN program interventions included screening tools, checklists, pocket cards, patient brochures, and utilizing the pharmacy management system to flag eligible patients. Patient knowledge gaps included naloxone misinformation and lack of awareness, while pharmacists demonstrated administrative, clinical, and counselling knowledge gaps. Naloxone availability was found to be highly variable, where independent and rural pharmacies were less likely to stock or dispense naloxone. Further, pharmacies located in districts with higher rates of opioid overdose deaths and lower household income were also less likely to have naloxone available. This review identified multiple new programs, showcasing that the implementation and evaluation of THN programs are an expanding area of research. Future research should focus on implementing and evaluating a THN program through a randomized controlled trial design that incorporates solutions for the barriers and knowledge gaps identified in this study.
Melatonin: From Pharmacokinetics to Clinical Use in Autism Spectrum Disorder

The role of melatonin has been extensively investigated in pathophysiological conditions, including autism spectrum disorder (ASD). Reduced melatonin secretion has been reported in ASD and led to many clinical trials using immediate-release and prolonged-release oral formulations of melatonin. However, melatonin’s effects in ASD and the choice of formulation type require further study. Therapeutic benefits of melatonin on sleep disorders in ASD were observed, notably on sleep latency and sleep quality. Importantly, melatonin may also have a role in improving autistic behavioral impairments. The objective of this article is to review factors influencing treatment response and possible side effects following melatonin administration. It appears that the effects of exposure to exogenous melatonin are dependent on age, sex, route and time of administration, formulation type, dose, and association with several substances (such as tobacco or contraceptive pills). In addition, no major melatonin-related adverse effect was described in typical development and ASD. In conclusion, melatonin represents currently a well-validated and tolerated treatment for sleep disorders in children and adolescents with ASD. A more thorough consideration of factors influencing melatonin pharmacokinetics could illuminate the best use of melatonin in this population. Future studies are required in ASD to explore further dose-effect relationships of melatonin on sleep problems and autistic behavioral impairments.
Clinical Comparison of Two Confrontation Naming Measures in Spanish-Speaking People with Epilepsy

Abstract Objective: Research on the lateralizing value of neuropsychological tests is limited among Latino people with epilepsy (PWE). This study aims to evaluate the utility of two confrontation naming measures in laterality determination. Method: Data were collected from 71 Latino PWE who completed the Vocabulario Sobre Dibujos (VSD) and the Pontón-Satz Modified Boston Naming Test (MBNT). Raw and standardized scores were examined to determine diagnostic accuracy for predicting left hemisphere (LH) epilepsy for the full sample and using a sample-specific median split of educational attainment. Results: The MBNT demonstrated adequate classification accuracy (65.7%, 77.1%) as did the VSD (54.3%, 74.3%) for predicting LH seizure laterality using raw and standardized scores, respectively. For participants with ≥ 9 years of education (HEdu), receiver operator characteristic curve analyses showed a raw/percentile cutoff of ≤ 26/≤ 5th on the VSD, yielding 53%–58% sensitivity/87%–83% specificity. A raw score cutoff of ≤ 17 on MBNT produced 47% sensitivity/78% specificity for HEdu participants. Conclusions: The VSD was found to have greater flexibility in determining cutoff scores using either raw or standardized scores for predicting seizure laterality. This study provides interpretation guidance, emphasizing education as a pertinent variable, to optimize lateralization accuracy for Latino PWE.
