AbstractObjectiveTo evaluate, through microcomputed tomography (μCT), the cement film thickness of veneers and crowns made with different provisional materials.Material and MethodsA veneer and a crown preparation were performed on a central incisor and a second molar of a dental model, respectively, scanned with an intraoral scanner, and the .stl files were exported to an LCD‐based SLA three‐dimensional (3D)‐Printer. Twenty‐four preparations were 3D‐printed for each veneer and crown and divided into four groups (n = 6/group): (a) Acrylic resin (Acrílico Marche); (b) Bisacrylic resin (Protemp 4); (c) PMMA computer‐aided design and computer‐aided manufacturing (CAD‐CAM) (Vipiblock); and (d) 3D‐printed resin for provisional restorations (Raydent C&B for temporary crown and bridge). Veneers and crowns restorations were performed and cemented with a flowable composite. Each specimen was scanned with a μCT apparatus, files were imported for data analysis, and cement film thickness was quantitatively measured. Data were analyzed by 2‐way ANOVA and Tukey post‐hoc tests (α = .05).ResultsCrowns presented a thicker cementation film than veneers (P < .05).The bisacrylic resin showed the smallest veneer film thickness, similar to the acrylic resin (P = .151), which was not significantly different than the PMMA CAD/CAM material (P = .153). The 3D printed provisional material showed the thicker film, different than all other materials (P < .05). The bisacrylic resin showed a cement film thickness with a high number of voids in its surface. For crowns cementation, the 3D printed provisional material showed the thicker cementation film, different than all other materials (P < .05).ConclusionsDifferent provisional materials present different film thicknesses. The 3D printed provisional material showed the highest veneer and crown film thicknesses. Veneers film thicknesses were smaller than crowns for all provisional materials.Clinical SignificanceThe 3D printed provisional material studied can be satisfactorily used, presenting appropriate adaptation with the tooth preparation, however, it shows the highest cement film thickness for both veneers and crowns cementations when compared with other provisional materials. A better internal fit, or smaller cement film thickness is obtained by CAD/CAM materials, acrylic and bisacrylic resins. Veneer cementation showed a smaller cement film thickness compared with crown cementation for all provisional materials.

Published: September 2020

The family therapy literature documenting the experiences of couple/marriage and family therapists (C/MFTs) of color as a group is limited. The purpose of this study was to assess the status of C/MFTs of color in their clinical training programs, clinical work, and related areas of professional challenges and opportunities. Participants (N = 113) completed a one‐time, anonymous electronic survey on SurveyMonkey consisting of demographic questions, closed‐ and open‐ended questions about their experiences. Key findings are reported related to C/MFTs of color experiences in training programs, areas of professional need, and working with racial and/or ethnic minority clients. These findings shed light on how social justice principles and practices upheld in our field are experienced from the emic perspectives of C/MFTs of color. These voices help to broaden our understanding of how we might move forward in advocating for and advancing a more culturally responsive agenda within our profession.

AimTo evaluate the feasibility of a two‐stage screening strategy for otitis media with effusion (OME) in pre‐school and school children. The risk factors of OME were also studied.MethodsOne hundred and eighty‐nine children aged 4–8 years were recruited. The two‐stage screening consisted of an on‐site screening with a portable otoscopy along with a questionnaire to both diagnose children with OME and identify children at risk, and a standard screening performed at a regional hospital for final diagnosis. The prevalence detected from the two‐stage screening approach was compared to the actual prevalence.ResultsThe detection rate of OME through the two‐stage screening approach was not significantly different from the actual prevalence rate (12.7% vs. 13.4%, P = 0.847). Children from the urban area had a lower risk for OME than that from the rural area (P = 0.007, odds ratio (OR) = 0.28, 95% confidence interval (CI): 0.11–0.74). Compared to childcare dining, family dining helped to reduce the chance of OME (P < 0.001, OR = 0.15, 95% CI: 0.06–0.38).ConclusionsThe two‐stage screening strategy was effective for screening for OME among pre‐school and school children. It can be used in rural areas that have a high prevalence of OME and limited medical resources.

Published: September 2020

AbstractQuestions(1) How much do abiotic site factors and land‐cover categories influence the course of succession across successional series at a country scale? (2) Are there any differences in the abiotic site factors and land‐cover categories which are responsible for driving primary and secondary seres? (3) Which of the factors influence species richness and participation of target species?LocationVarious disturbed sites in the Czech Republic, Central Europe.MethodsThe Database of Successional Series (DaSS) was compiled of 21 different types of succession, comprising 2,846 phytosociological relevés. The stages ranged from 1 to >150 years in age. Abiotic site factors included macroclimate characteristics and substrate; landscape factors comprised various land‐cover categories in a radius of 1 km around each sampled site. Principal Coordinate Analysis of Neighbour Matrices (PCNM) was performed to quantify the effect of abiotic site factors and landscape factors on seral vegetation, also regarding the primary or secondary status of succession. The relationships between number of species, number and proportion of target species and abiotic site and landscape factors were further assessed using generalised linear model analysis.ResultsAll considered abiotic and landscape factors were found to have significant effects on the course of succession. The effects of abiotic site factors appeared to be more important than those of the surrounding landscape structure. Species richness was higher on basic substrates. The proportion of target species increased with increasing woodland area in the surrounding and with a wetter and colder climate, and decreased with urbanisation rate of the landscape.ConclusionNot only local but landscape factors, such as climate and land cover, should be considered in any study of succession, as they substantially influence the general successional pattern. Quantification of the role of these environmental factors may help to decide where a spontaneous restoration is a viable option for the restoration of disturbed sites. The primary or secondary status of succession is less relevant than has usually been supposed.
Seminal fluid protein divergence among populations exhibiting postmating prezygotic reproductive isolation

AbstractDespite holding a central role in fertilization, reproductive traits often show elevated rates of evolution and diversification. The rapid evolution of seminal fluid proteins (Sfps) within populations is predicted to cause mis‐signalling between the male ejaculate and the female during and after mating resulting in postmating prezygotic (PMPZ) isolation between populations. Crosses between Drosophila montana populations show PMPZ isolation in the form of reduced fertilization success in both noncompetitive and competitive contexts. Here we test whether male ejaculate proteins produced in the accessory glands or ejaculatory bulb differ between populations using liquid chromatography tandem mass spectrometry. We find more than 150 differentially abundant proteins between populations that may contribute to PMPZ isolation, including a number of proteases, peptidases and several orthologues of Drosophila melanogaster Sfps known to mediate fertilization success. Males from the population that elicit the stronger PMPZ isolation after mating with foreign females typically produced greater quantities of Sfps. The accessory glands and ejaculatory bulb show enrichment for different gene ontology (GO) terms and the ejaculatory bulb contributes more differentially abundant proteins. Proteins with a predicted secretory signal evolve faster than nonsecretory proteins. Finally, we take advantage of quantitative proteomics data for three Drosophila species to determine shared and unique GO enrichments of Sfps between taxa and which potentially mediate PMPZ isolation. Our study provides the first high‐throughput quantitative proteomic evidence showing divergence of reproductive proteins between populations that exhibit PMPZ isolation.

AbstractBackgroundDeep vein thrombosis and its progression to pulmonary thromboembolism is a major source of mortality in patients with neuromuscular disease. Furthermore, ventilator use poses a high risk of DVT to patients.MethodsHospitalized patients with neuromuscular disease who underwent tracheotomy with positive pressure ventilation (TPPV) had DVT evaluated in the lower extremities by ongoing whole leg venous ultrasonography. Patients who were diagnosed with DVT underwent a second ultrasonography 1 month later. The attending physicians decided on therapeutic measures. All patients were followed during the study period.ResultsEight of 33 patients had DVT. The site of DVT formation was the iliac veins in three cases, femoral veins in two cases, and calf veins in three cases. All of the patients with DVT were asymptomatic. There was no difference in the clinical future between patients with DVT and those without DVT. Progression of DVT was not observed in the second ultrasonographic examination 1 month later. All patients with DVT had an excellent prognosis after a follow‐up period of 9 months.ConclusionThe prevalence of DVT in patients with neuromuscular disease who undergo TPPV might be high. Further large studies on this issue are required because the clinical significance of this DVT is uncertain.

AbstractIndividuals with epidermolysis bullosa (EB), a group of genodermatoses with skin fragility, often require specialized and expensive bandaging. We analyzed the results from an online survey of 249 EB patients and caregivers living in the United States to investigate the financial impact of EB. Of respondents with severe EB subtypes (recessive dystrophic and junctional), 73% reported a major or moderate financial impact and 26% spent greater than $1000 per month on wound care supplies. These results demonstrate the high financial burden associated with epidermolysis bullosa in the United States and support the need for a federally funded EB bandage program.

AbstractThe current event‐related potential study investigated the perceptual processing of the categorization advantage of happy over sad faces in social anhedonia with a nonclinical sample. A high social anhedonia (HSA, N = 25) group and a low social anhedonia (LSA, N = 27) group performed a facial expression categorization task during which they classified facial expressions (happy, neutral, sad), irrespective of face orientation (upright, upside‐down). Behaviorally, happy faces were identified more quickly than sad ones in the upright but not inverted orientation. Electrophysiologically, the LSA group showed earlier N170 latencies for happy than for sad faces in the upright but not upside‐down orientation, whereas the HSA group did not show any expression effect on N170 latencies. Moreover, N170 and P2 amplitude results revealed that HSA relative to LSA individuals showed delayed neural discrimination between happy and sad faces. These results suggest that social anhedonia is associated with a deficit of perceptual processing during facial expression categorization.
Response dependence of reversal‐related ERP components in perception of ambiguous figures
Authors: Abdallah Diane , Brooks Joseph L. 
Published: September 2020

AbstractPerceptual multi‐stability is characterized by alternating interpretations of an unchanging stimulus input. The reversal negativity (RN) and reversal positivity (RP) ERP components show differences in electrophysiological responses between trials on which participants experience a perceptual reversal of a multi‐stable stimulus versus trials without a reversal (i.e., stable). However, it is unclear to what extent these two ERP components reflect reversal‐related perceptual processing rather than task and response processes. To address this, we varied task and response requirements while measuring the RN and RP. In the standard reversal task, participants indicated whether they saw a perceptual reversal on each trial. In contrast, in the identity task participants reported perceived identity of the stimulus (e.g., face or vase) without any reference to reversals. In some blocks, reversal trials required a response whereas in other blocks stable trials required a response. We found that the RN appeared independently of task and response style. However, the early latency RP component was only present when participants responded manually. For non‐response trials, a component was found during the same latency as the RP but with inverted polarity. Our results suggest that the early RP component is dependent on response‐related processes rather than being a pure neural signature of perceptual processes related to endogenous perceptual reversals.
Healthcare Access among Older Rural Women Veterans in Utah*

Published: September 2020

AbstractUsing gender and life course frameworks attuned to overlapping roles and statuses, this exploratory case study highlights the experiences of older, rural female veterans in Utah with accessing Veterans Administration and other healthcare. Based on three focus groups with 22 women, findings show that these veterans experienced similar healthcare access obstacles to female veterans in other contexts. Most also experienced invisibility and discrimination in the military, which carried over as they became veterans. However, while these older, rural women veterans voiced new concerns about their own healthcare in later life course stages, they also described extensive experience with coordination of services and advocacy for other veterans, family and rural community members. Thus, these women veterans acted as healthcare advocates in a complex, bureaucratic, strained system. Feeling largely excluded from the male veterans' networks and organizations, they perceived the need to create new networks that could assist veterans in need.

AbstractKidney transplant recipients have been supposed vulnerable to severe Covid‐19 infection, due to their comorbidities and immunosuppressive therapies. Mild‐term complications of Covid‐19 are currently unknown, especially in this population. Herein, we report two cases of BKV replication after non‐severe SARS‐CoV‐2 infection. The first case was a 59‐year‐old man, transplanted 3 months ago, with recent history of slight BKV viremia (3.3 log10 DNA copies/ml). Despite strong reduction of maintenance immunosuppression (interruption of mycophenolic acid and important decrease of calcineurin inhibitors), BKV replication largely increased after Covid‐19 and viremia persisted at 4.5 log copy/ml few months later. The second case was a 53‐year‐old woman, transplanted 15 years ago. She had a recent history of BKV cystitis, which resolved with a decrease of MPA dosage. Few weeks after SARS‐CoV‐2 infection, she presented recurrence of lower urinary tract symptoms. Our reports highlight that SARS‐CoV‐2 infection, even without severity, could disrupt immune system and particularly lymphocytes, thus leading to viral replication. Monitoring of viral replications after Covid‐19 in kidney transplant recipients could permit to confirm these preliminary observations.

AbstractTumour stage has been demonstrated to have prognostic significance in canine oral malignant melanoma (OMM). Various evaluation techniques of positron emission tomography/computed tomography (PET/CT) have been reported for staging of head‐and‐neck tumours in people, but canine‐specific data are limited, and reports for CT accuracy have been variable. In this prospective study, the head/neck of client‐owned dogs with cytologically or histologically diagnosed OMM were imaged with18Fluorine‐fluorodeoxyglucose (18F‐FDG) PET/ CT. Bilateral mandibular lymphadenectomy was performed for histopathologic assessment. Two evaluation techniques for CT and PET were applied by four independent observers. CT evaluation utilized both a standardized grading scheme and a subjective clinical interpretation. PET evaluation was first performed solely on18F‐FDG‐uptake in lymph nodes compared to background on a truncated scan excluding the oral cavity. Subsequently, the entire head/neck scan and standardized uptake value (SUV) measurements were available. Receiver operating characteristic analysis was performed with histopathology as gold standard. Twelve dogs completed the study and metastatic OMM was identified in six mandibular lymph nodes from five dogs. Of the CT‐interpretation techniques, use of clinical grading performed best (sensitivity = 83% and specificity = 94%). Both PET techniques resulted in 100% sensitivity, but primary tumour site evaluation and use of SUV increased specificity from 78% to 94%. The SUVmax cut‐point, 3.3, led to 100% sensitivity and 83% specificity. In this population of dogs, PET appeared to be highly sensitive but at risk of being less specific without use of appropriate parameters and thresholds.
Predictive Capability Maturity Quantification Using Bayesian Network

Published: September 2020

Abstract
In nuclear engineering, modeling and simulations (M&Ss) are widely applied to support risk-informed safety analysis. Since nuclear safety analysis has important implications, a convincing validation process is needed to assess simulation adequacy, i.e., the degree to which M&S tools can adequately represent the system quantities of interest. However, due to data gaps, validation becomes a decision-making process under uncertainties. Expert knowledge and judgments are required to collect, choose, characterize, and integrate evidence toward the final adequacy decision. However, in validation frameworks, CSAU: code scaling, applicability, and uncertainty (NUREG/CR-5249) and EMDAP: evaluation model development and assessment process regulatory guide (RG 1.203), such a decision-making process is largely implicit and obscure. When scenarios are complex, knowledge biases and unreliable judgments can be overlooked, which could increase uncertainty in the simulation adequacy result and the corresponding risks. Therefore, a framework is required to formalize the decision-making process for simulation adequacy in a practical, transparent, and consistent manner. This paper suggests a framework—“Predictive capability maturity quantification using Bayesian network (PCMQBN)”—as a quantified framework for assessing simulation adequacy based on information collected from validation activities. A case study is prepared for evaluating the adequacy of a Smoothed Particle Hydrodynamic simulation in predicting the hydrodynamic forces onto static structures during an external flooding scenario. Comparing to the qualitative and implicit adequacy assessment, PCMQBN is able to improve confidence in the simulation adequacy result and to reduce expected loss in the risk-informed safety analysis.

Purpose: To examine whether concurrent heat and intermittent hypoxic training can improve endurance performance and physiological responses relative to independent heat or temperate interval training. Methods: Well-trained male cyclists (N = 29) completed 3 weeks of moderate- to high-intensity interval training (4 × 60 min·wk−1) in 1 of 3 conditions: (1) heat (HOT: 32°C, 50% relative humidity, 20.8% fraction of inspired oxygen, (2) heat + hypoxia (H+H: 32°C, 50% relative humidity, 16.2% fraction of inspired oxygen), or (3) temperate environment (CONT: 22°C, 50% relative humidity, 20.8% fraction of inspired oxygen). Performance 20-km time trials (TTs) were conducted in both temperate (TTtemperate) and assigned condition (TTenvironment) before (base), immediately after (mid), and after a 3-week taper (end). Measures of hemoglobin mass, plasma volume, and blood volume were also assessed. Results: There was improved 20-km TT performance to a similar extent across all groups in both TTtemperate (mean ±90% confidence interval HOT, −2.8% ±1.8%; H+H, −2.0% ±1.5%; CONT, −2.0% ±1.8%) and TTenvironment (HOT, −3.3% ±1.7%; H+H, −3.1% ±1.6%; CONT, −3.2% ±1.1%). Plasma volume (HOT, 3.8% ±4.7%; H+H, 3.3% ±4.7%) and blood volume (HOT, 3.0% ±4.1%; H+H, 4.6% ±3.9%) were both increased at mid in HOT and H+H over CONT. Increased hemoglobin mass was observed in H+H only (3.0% ±1.8%). Conclusion: Three weeks of interval training in heat, concurrent heat and hypoxia, or temperate environments improve 20-km TT performance to the same extent. Despite indications of physiological adaptations, the addition of independent heat or concurrent heat and hypoxia provided no greater performance benefits in a temperate environment than temperate training alone.
