AbstractIntroductionTo evaluate short‐term efficacy and incidence of ablation‐induced endoscopically detected esophageal injury in patients undergoing high‐power, short‐duration (HPSD) pulmonary vein isolation using a novel irrigated radiofrequency ablation catheter and ablation generator setup.Methods and ResultsAtrial fibrillation (AF) patients, who underwent AF ablation using an irrigated radiofrequency ablation catheter specifically designed for a HPSD ablation approach (50 W, with a target Ablation Index of 350 at posterior wall), received postablation esophageal endoscopy after ablation. In total 45 consecutive patients (67 ± 10 years; 58% male; 42% paroxysmal AF) undergoing AF ablation using a specialized ablation catheter (QDOT) were included in the study. Thirty‐one of 45 patients (69%) underwent a first‐time pulmonary vein isolation (Group 1, 67 ± 11 years; 55% male; 48% paroxysmal AF). Fourteen patients (31%) underwent a redo AF procedure (Group 2, 66 ± 8 years; 64% male; 29% paroxysmal AF). Patients undergoing first‐time pulmonary vein isolation were included in the final analysis. In these patients an endoscopically detected esophageal lesion (EDEL) was detected in 5 of 31 (16%) patients (erosion n = 2, ulcer n = 3). Mean contact force at posterior wall ablation sites was significantly lower in patients with postprocedural EDEL compared with patients without EDEL (11.9 ± 0.8 g vs. 15.6 ± 4.7 g).ConclusionPVI using a specialized high‐power ablation catheter in conjunction with a HPSD ablation approach results in a 16% incidence of EDEL in first AF ablation candidates. Future studies evaluating high‐power short duration ablation strategies should include esophageal endoscopy to estimate the risk of clinically relevant esophageal complications.

AbstractObjectiveTo investigate the probability of survival and failure modes of four‐unit implant‐supported porcelain fused to metal (PFM) dentogingival prostheses subjected to step‐stress accelerated life testing (SSALT).Materials and methodsEighteen implant‐supported PFM dentogingival prostheses with thin metallic infrastructures, which provided minimal ceramic support and improved esthetics were fabricated over external hexagonal connection UCLA abutments. SSALT was performed until specimen failure. Use level probability Weibull curve and reliability were calculated and plotted. Weibull modulus (m) and characteristic strength (η) were also calculated. Polarized light microscope and scanning electron microscope were used to characterize fractures.ResultsFailures were dictated by material strength rather than fatigue damage accumulation. The probability of survival for loads reaching 100 and 150 N in 100,000 cycles was 92 and 61%, respectively. No cracks or fractures were identified in the veneered porcelain, whereas abutment fixation screw fracture was the chief failure mode.ConclusionImplant‐supported PFM four‐unit dentogingival prostheses with minimum metal framework dimensions presented favorable lifetime prediction under fatigue testing. Fractures were restricted to fixation screws.Clinical significanceIn‐vitro fatigue testing and failure mode analyses evidenced favorable lifetime prediction for 4‐unit implant‐supported dentogingival prostheses with minimum metal frameworks. Abutment fixation screw fracture might be the most frequent clinical complication. Since this proof of concept has been tested in‐vitro, further studies including different restorative materials, as well as long‐term clinical trials are warranted.

AbstractArgyrops spinifer and Rhabdosargus haffara are two sympatric seabream species making important contributions to fisheries landings in the western Arabian/Persian Gulf. We identified the strengths and weaknesses in the long‐term sustainability of A. spinifer and R. haffara stocks by integrating multiple sources of data, including fisheries catch and effort statistics, life history traits, scientific trawl surveys and historical length frequency distribution. Four strengths were identified in A. spinifer: wide distribution of juveniles, positive association to the network of de facto fishing exclusion areas created by hundreds of oil‐gas facilities, early maturation and the existence of large and old individuals. A. spinifer suffers from two potential weaknesses: slow growth rate and higher exploitation pressure on the small‐sized individuals. R. haffara, on the other hand, has a strength of having a short life span and a fast growth rate, characteristics that make it robust to unfavourable conditions. R. haffara suffers from two weaknesses: the lack of association to the oil and gas facilities, and the preference for nearshore shallow waters with stronger negative anthropogenic impacts. Identified strengths and weaknesses of these two sparids provided a preliminary assessment about their long‐term sustainability, as well as a roadmap about how to develop different management strategies to meet specific objectives.
Continuous outmigration and sequential encountering of environmental cues are important for successful homing of hatchery‐reared, anadromous brown trout Salmo trutta
Authors: Jonsson Bror , Jonsson Nina 
Published: January 2021

AbstractWhen rehabilitating and reintroducing trout Salmo trutta in rivers, it is a goal that as many as possible survive, home and form self‐sustaining populations. Hatchery‐reared, anadromous S. trutta have significant lower ability to return to the area where they were raised if (a) transported in a closed tank to sea and released 5 km from the River Imsa, relative to those that were (b) transported when swimming in a partly submerged tank with sea water run‐through, while being slowly towed by a boat the same distance or (c) released at the outlet of the River Imsa. Thus, if deprived from environmental cues during part of the way, they lose their ability to home.
Evaluation of sodium hypochlorite and peroxyacetic acid to prevent transfer of surface‐attached Listeria monocytogenes to produce

Published: January 2021

AbstractSporadic contamination of produce with Listeria monocytogenes (Lm) is a recurrent problem. Ways for contamination to occur include transfer of the pathogen to produce from processing surfaces or soil particles to which it has become attached. Since it is known that surface‐attached Lm is less susceptible to antimicrobials than Lm grown in liquid culture, the goal of the current study was to determine if Lm grown on surfaces and released into water retained its higher tolerance of antimicrobials. In addition, transfer of Lm from surfaces or soil particles to blueberries, mung beans and spinach leaves in the presence of the antimicrobials, sodium hypochlorite (NaOCl) adjusted to pH 6.8 and peroxyacetic acid (PAA), was studied. The experiments were carried out with a cocktail of six Lm strains and strains obtained from produce processing plants. Results indicated that Lm released from surfaces was as susceptible to the two antimicrobials as Lm grown in liquid culture and was inactivated within seconds by an initial concentration of 100 ppm of NaOCl or PAA. Transfer of Lm grown on stainless steel coupons to blueberries in wash water was not observed at NaOCl concentrations as low as 20 ppm. In contrast, transfer of Lm from washed soil particles (COD = 1.7 ± 0.89 mg/l) in contact with mung beans was observed even at initial NaOCl or PAA concentrations of 250 ppm. Lm released from washed soil particles to which it was attached to spinach leaves could be detected in the presences of 20 ppm of NaOCl and PAA and occasionally even in the presence of 100 and 250 ppm of the antimicrobials.
“The troublesome other and I”: Parallel stories of separated parents in prolonged conflicts

Published: January 2021

AbstractThis qualitative study aims to explore how noncohabiting parenting couples in prolonged conflict construct the other parent and themselves. Ten parents from five parent couples were interviewed. A dyadic analytical design was used, where parent's stories of conflict were analyzed in parallel with their co‐parent. Drawing on positioning theory, self‐identity as parents emerged as implicit counter positions in storylines, which construct the co‐parent as “the troublesome other.” Two typologies of conflicted storylines were prominent in the findings:storylines of violations of trust, positioning the co‐parents in relation to traumatic events in the past and,storylines of who is bad, positioning the co‐parent as either a disloyal co‐parent or a dysfunctional parent. The findings indicate that prolonged conflicts made it impossible to find available positions for cooperation. We argue that family therapists should aid each household toward promoting child and family resilience rather than continued efforts to solve chronic conflicts.
Adult ADHD and romantic relationships: What we know and what we can do to help

Published: January 2021

AbstractIt has been widely maintained that enduring and healthy romantic relationships are critical to quality of life in adulthood, and can buffer the impact of adversity, including psychological disorder. Unfortunately, much research points toward adults with attention‐deficit hyperactivity disorder (ADHD) having short‐lived and discordant romantic relationships. Despite this ample evidence, relatively little research has focused on identifying specific factors that may strengthen or explain their relational difficulties, which would have obvious relationship distress prevention and intervention implications. The current study reviews the state of the literature on romantic relationships in adults with ADHD, including differences that have been established between ADHD and non‐ADHD populations as well as distal and proximal factors that appear to increase risk of relationship distress of adults with ADHD. Finally, notable gaps in the literature are identified and implications are raised with regards to prevention and intervention efforts designed to address functional impairment in adults with ADHD.
Estimation of an uncertainty budget and performance measurement for a dual‐wavelength Twyman‐Green interferometer
Authors: Ibrahim Dahi Ghareab Abdelsalam 
Published: January 2021

AbstractIn this paper, the uncertainty budget from 10 sources we claim they have direct impact on measurement is estimated. The measurement has been applied to nominal step heights of 1.34 and 1.50 μm using a dual‐wavelength Twyman‐Green interferometer. Experimental results show that the measured step heights match with their nominal values with expanded uncertainty in the range of 5% from the object being measured. The performance of the measurement process over time has been estimated at different confidence levels and the obtained results show that the process is maintained in a state of statistical control. To the best of our knowledge, this is the first report for estimation of uncertainty budget from a synthetic wavelength.
Reconstructing 3D digital model without distortion for poorly conductive porous rock by nanoprobe‐assisted FIB‐SEM tomography

Published: January 2021

AbstractOil and natural gas prospecting requires precise pore characterisation of insulating rock samples, which involves severe charging problems in the state‐of‐art FIB‐SEM tomography, such as overexposure, drift and distortion. For weak cemented samples with very poor conductivity, the conventional ways such as decreasing accelerating voltage or current as well as coating a thin layer of carbon or gold fail to eliminate all the detrimental effect, leading to image distortion in the form of lateral shift and longitudinal stretching. A new nanoprobe‐assisted method is explored in FIB‐SEM tomography to address this problem and improve image quality. To be specific, a metallic nanoprobe is induced and attached on the sample surface to create an express path for the export of excess electrons near the region of interest, which effectively removes distortion and drift when imaging. Two adjacent areas were characterised and reconstructed into 3D digital models by FIB‐SEM tomography with nanoprobe‐assisted method applied to one region only. The lateral shift creates zigzag feature for distorted region and the longitudinal stretching of undistorted object can reach 14%. Average pore size of distorted region is larger than that of the undistorted region, however considering the longitudinal stretching, the average pore size of distorted region can be corrected to the same level as the undistorted region. The systematic error caused by distortion for poorly conductive porous rock is hazardous for digital rock physics analysis. Therefore, the nanoprobe‐assisted FIB‐SEM tomography should be regarded as a one of the optional and feasible procedures in case decreasing accelerating voltage or current as well as coating a thin layer of conductive material does not work.

AbstractAims and ObjectivesTo compare knowledge, anxiety, academic concerns and preventative behaviours between undergraduate nursing students in Australia and India during the COVID‐19 pandemic.BackgroundBased on the World Health Organization's direction for containment of the novel coronavirus (COVID‐19), countries implemented varying levels of restrictions including closure of university campuses and providing on line undergraduate education.MethodsStudents in NSW, Australia and Kerala, India completed an online survey assessing their (a) knowledge and source of information about COVID‐19; (b) anxiety; and coping strategies; (c) academic concerns; and (d) preventative behaviours. Descriptive and inferential statistics were used to summarise the data.ResultsData from 99 Australian and 113 Indian undergraduate nurses were analysed. Greater number of Indian students indicated having sufficient knowledge of COVID‐19 (OR 0.22; 95% CI 0.08, 0.63), getting information about COVID‐19 from social media (OR 0.03; 95% CI 0.01, 0.07) and being concerned about ‘attending clinical placement’ (MD‐1.08; 95% CI −1.94, −0.23). Australian students reported significantly higher levels of anxiety (MD 1.99 95% CI 1.21, 2.78), difficulty sleeping (OR 18.00; 95% CI 6.76, 47.96), concentrating (OR 33.22; 95% CI 13.85, 79.67) and eating (OR 14.05; 95% CI 3.19, 61.84). Greater number of Australian students indicated that they would go to the University if they needed to meet with other students (OR 9.21; 95% CI 3.08, 27.55), had to access the library (OR 7.20; 95% CI 3.26, 15.90) or had a group assignment (OR 2.93; 95% CI 1.26, 6.77).ConclusionsWide variations were present in knowledge, anxiety, academic concerns and preventative behaviours among undergraduate nursing students in two countries.Relevance to clinical practiceUndergraduate students may benefit from additional support from the University and staff in the clinical setting with online learning and resources in order to adjust to the ‘new normal’ and enable them to achieve academic success.

AbstractAimCardiotocography is used worldwide to evaluate fetal well‐being during pregnancy and labor. In past guidelines, the management plan was determined based on the assessment of the most severe waveform. There are no guidelines for evaluating the integrated recurrent decelerations; however, we believe their assessment to be essential for predicting the status of the fetus. The objective of this study was to propose an indicator for performing medical interventions during labor by creating a scoring system that reflects integrated recurrent decelerations.MethodsIn this retrospective cohort study, we included data for only full‐term single fetus births from vaginal deliveries. The score named the iPREFACE score (integrated score index to predict fetal acidemia by intrapartum fetal heart rate monitoring) was calculated using cardiotocography findings from continuing 30 min before delivery. We examined the iPREFACE score and fetal acidemia association and calculated the cut‐off iPREFACE scores for acidemia using receiver operating characteristic curves.ResultsThe study included 469 delivery cases. Their iPREFACE scores exhibited a significant negative correlation with the umbilical artery blood pH (correlation coefficient; −0.43). The cut‐off iPREFACE scores for the umbilical artery blood with pH <7.20, <7.10 and <7.0 were 44, 46 and 67, respectively (the areas under the curve were 0.776, 0.962 and 0.996, respectively).ConclusionThe iPREFACE score may predict fetal acidemia and could be used as an indicator for timely medical interventions during labor. Because assessments using a cardiotocography are quick and easy to perform, the iPREFACE score could be a valuable tool in clinical practice.

AbstractPurposeThe purpose of this study is to analyze the frequency and elevate the awareness of the prevalence of nondental pathology in cone beam computed tomography (CBCT) scans taken for implant placement treatment planning and postplacement evaluation. The data from the CBCT should be read by an oral and maxillofacial radiologist for proper diagnosis of dental and nondental pathology and referred to the medical specialist for proper management when necessary.Materials and methodsThis retrospective study analyzed 1002 consecutive CBCT scans taken at a single private practice noting the prevalence of nondental pathology in CBCT images for all dental implant procedures. All scans were taken from November 2007 to March 2020. One board certified oral and maxillofacial radiologist systemically read all scans and reported all findings in the maxilla and mandible, condyles and TMJ, paranasal sinuses, nasal fossa, pharyngeal airway, skull base and temporal bone, neck soft tissues, and cervical spine. The incidental findings, variation of normal anatomy, or pathology reported in these structures were categorized based on anatomic location and significance and the incidence was investigated.ResultsPathologies ranged from innocuous sinusitis, to more serious atherosclerotic calcification of the carotid arteries, narrowed airways, and neoplastic lesions. Fifty‐one different findings were noted, of which 36 were pathologies that required referral or follow‐up.ConclusionsIncidental findings can be detected in CBCT scans for dental implants. The clinician must be familiar with the radiographic diagnosis of head and neck pathology, and/or must refer these images to an appropriate specialist for the radiographic interpretation of the full volume.
Developmental Associations Between Sympathy and Mutual Disclosure in Friendships From Mid‐Adolescence to Early Adulthood

Published: January 2021

Sympathy is regarded as an important precursor to the development of emotional intimacy, including mutual disclosure. In turn, emotional intimacy is assumed to foster the development of sympathy. Yet, research has not examined how sympathy and mutual disclosure in generic friendships are mutually related to one another during mid‐adolescence to early adulthood. Data came from three waves of the Swiss Survey of Children and Youth (COCON; N = 1,258). Bidirectional links between sympathy and mutual disclosure were tested with autoregressive cross‐lagged panel analyses. Sympathy at age 15 was associated with mutual disclosure in friendships at 18, which in turn was associated with sympathy at 21. Multi‐group models suggested that our model better describes these processes in females than in males.

AbstractRapid diagnostic tests as an attractive alternative to enzyme immunoassay could identify hepatitis C virus (HCV) infected persons more expeditiously. The availability of high performing and quality‐assured rapid diagnostic tests are essential to scale‐up HCV screening. The study was undertaken to evaluate the performance of seven domestic HCV rapid diagnostic tests kits. The kits were evaluated by using HCV serum panels, including HCV basic panel, analytical specificity panel, mixed titre performance panel, characteristic panel, seroconversion panel, and genotype qualification panel. The results showed that clinical sensitivity, clinical specificity and analytical specificity of seven rapid diagnostic tests kits ranged from 94% (95% CI: 83.2–98.6) to 100% (95% CI: 91.5–100). Furthermore, specimens with HCV genotypes 1b, 2a, 3a, 4a, 5a, 6 could be detected by HCV rapid diagnostic tests kits, whereas specimens with genotypes 1a and 2b could not be detected. Additionally, most HCV rapid diagnostic tests kits had great performance in diagnosing different titres and/or different bands samples, but some low S/CO value specimens may not be fully detected by few rapid diagnostic test kits. In conclusion, seven HCV rapid diagnostic tests reagents presented high sensitivity, specificity, good anti‐interference and detection ability of early infection, which could meet the requirements of clinical HCV antibody screening.
