Authors: Eugene-Okorie Joy O. , Obiora Daniel N. , Ibuot Johnson C. , Ugbor Desmond O. 
Published: September 2020

AbstractElectrical resistivity survey employing vertical electrical sounding was carried out in Oraifite, Southeastern Nigeria, involving a total of twenty soundings across, in order to assess the groundwater potential and the aquifer vulnerability in Oraifite. The field data were interpreted using the WINRESIST software, and the resulting geoelectric curves give the resistivities, depths and thicknesses of each geoelectrical layer. Dar Zarrouk parameters and aquifer transmissivity were computed using the values of aquifer resistivity and thickness. From the results, variations of the computed parameters were observed. Aquifer resistivity ranges from 420.1 to 27,585.8 Ωm having an average value of 4906.3 Ωm, while its thickness varies from 13.4 to 93. 9 m. Longitudinal conductance varies from 0.0015 to 0.2136 Ω−1, transverse resistance ranges from 29,388.88 to 1,158,604.0 Ωm2, while the transmissivity varies from 1.1692 to 123.7905m2/day. The contour maps reveal the distributions of these parameters, which help in delineating zones with different layer characteristics. The result from this study can be a reference for decision making in the abstraction and management of groundwater repositories.

AbstractPancreatectomy with arterial resection is a treatment option in selected patients with locally advanced pancreatic cancer. This study aimed to identify factors predicting cancer-specific survival in this patient population. A single-Institution prospective database was used. Pre-operative prognostic factors were identified and used to develop a prognostic score. Matching with pathologic parameters was used for internal validation. In a patient population with a median Ca 19.9 level of 19.8 U/mL(IQR: 7.1–77), cancer-specific survival was predicted by: metabolic deterioration of diabetes (OR = 0.22, p = 0.0012), platelet count (OR = 1.00; p = 0.0013), serum level of Ca 15.3 (OR = 1.01, p = 0.0018) and Ca 125 (OR = 1.02, p = 0.00000137), neutrophils-to-lymphocytes ratio (OR = 1.16; p = 0.00015), lymphocytes-to-monocytes ratio (OR = 0.88; p = 0.00233), platelets-to-lymphocytes ratio (OR = 0.99; p = 0.00118), and FOLFIRINOX neoadjuvant chemotherapy (OR = 0.57; p = 0.00144). A prognostic score was developed and three risk groups were identified. Harrell’s C-Index was 0.74. Median cancer-specific survival was 16.0 months (IQR: 12.3–28.2) for the high-risk group, 24.7 months (IQR: 17.6–33.4) for the intermediate-risk group, and 39.0 months (IQR: 22.7–NA) for the low-risk group (p = 0.0003). Matching the three risk groups against pathology parameters, N2 rate was 61.9, 42.1, and 23.8% (p = 0.04), median value of lymph-node ratio was 0.07 (IQR: 0.05–0.14), 0.04 (IQR:0.02–0.07), and 0.03 (IQR: 0.01–0.04) (p = 0.008), and mean value of logarithm odds of positive nodes was − 1.07 ± 0.5, − 1.3 ± 0.4, and − 1.4 ± 0.4 (p = 0.03), in the high-risk, intermediate-risk, and low-risk groups, respectively. An online calculator is available at www.survivalcalculator-lapdac-arterialresection.org. The prognostic factors identified in this study predict cancer-specific survival in patients with locally advanced pancreatic cancer and low Ca 19.9 levels undergoing pancreatectomy with arterial resection.

Published: September 2020

AbstractIn the present investigation, an attempt has been made to investigate the replacement compatibility of conventional austenitic stainless steel (316L) with low-Ni austenitic stainless steel (201) by employing their dissimilar welding using gas tungsten arc welding technique with varying heat input. The effects of heat input on the microstructural, mechanical, and corrosion properties were studied. The result depicts the balanced austenite/ferrite content in the fusion zone for both the heat inputs. The low heat input process, which results in a faster cooling rate, demonstrates higher tensile strength and microhardness. Similarly, the pitting corrosion resistance of the fusion zone demonstrates better properties on the low heat input process attributed to the lesser dendritic length and lesser interdendritic arm spacing.
Older Women’s Perspectives Driving Mammography Screening Use and Overuse: a Narrative Review of Mixed-Methods Studies
Authors: Austin Jessica D. , Shelton Rachel C. , Lee Argov Erica J. , Tehranifar Parisa 
Published: September 2020

Abstract
Purpose of Review
Examining what older women know and perceive about mammography screening is critical for understanding patterns of under- and overuse, and concordance with screening mammography guidelines in the USA. This narrative review synthesizes qualitative and quantitative evidence around older women’s perspectives toward mammography screening.

Recent Findings
The majority of 43 identified studies focused on promoting mammography screening in women of different ages, with only four studies focusing on the overuse of mammography in women ≥ 70 years old. Older women hold positive attitudes around screening, perceive breast cancer as serious, believe the benefits outweigh the barriers, and are worried about undergoing treatment if diagnosed. Older women have limited knowledge of screening guidelines and potential harms of screening.

Summary
Efforts to address inequities in mammography access and underuse need to be supplemented by epidemiologic and interventional studies using mixed-methods approaches to improve awareness of benefits and harms of mammography screening in older racially and ethnically diverse women. As uncertainty around how best to approach mammography screening in older women remains, understanding women’s perspectives along with healthcare provider and system-level factors is critical for ensuring appropriate and equitable mammography screening use in older women.
Blended Treatment for Depressive Disorders in Youth: a Narrative Review
Authors: Rasing Sanne P. A. 
Published: September 2020

AbstractDepressive disorders are the most prevalent mental health disorder in adolescents with detrimental consequences; effective and available treatment is crucial. Face-to-face and computerized treatments both have advantages but also downsides. Merging these two into one so-called blended treatment seems to be an optimal combination of elements. This current review addresses blended treatment for youth depression and aims to summarize existing knowledge on effectiveness as well as patients’ and therapists’ perspectives. Results showed promising significant decreases in symptoms, but no evidence for differences between blended and face-to-face treatment was found. Patients’ perspectives were mixed; they reported strong preferences for face-to-face treatment, but participants actually receiving blended treatment were mainly positive. Therapists’ attitudes were neutral, but they expressed their worries about the unknown risks on adverse events. Future research is needed and should, beside effectiveness and cost-effectiveness, pay close attention to the risks that are mentioned by therapists.
Finite Element Investigation of the Influence of SiC Particle Distribution on Diamond Cutting of SiCp/Al Composites

Published: September 2020

AbstractCharacteristics of internal microstructures have a strong impact on the properties of particulate reinforced metal composites. In the present work, we perform finite element simulations to elucidate fundamental mechanisms involved in the ultra-precision orthogonal cutting of aluminum-based silicon carbide composites (SiCp/Al), with an emphasis on the influence of particle distribution characteristic. The SiCp/Al composite with a particle volume fraction of 25 vol% and a mean particle size of 10 μm consists of randomly distributed polygon-shaped SiC particles, the elastic deformation and brittle failure of which are described by the brittle cracking model. Simulation results reveal that in addition to metal matrix tearing, cutting-induced particle deformation in terms of dislodging, debonding, and cracking plays an important role in the microscopic deformation and correlated machining force variation and machined surface integrity. It is found that the standard deviation of particle size to the mean value has a strong influence on the machinability of microscopic particle–tool edge interactions and macroscopically observed machining results. The present work provides a guideline for the rational synthesis of particulate-reinforced metal composites with high machinability.
Rapid Conversion of a Biomedical Engineering Laboratory from in Person to Online

Published: September 2020

AbstractTemporary higher education institution closures in response to the 2020 COVID-19 pandemic disrupted student teaching. This paper reports on the rapid conversion of an in person laboratory session to online delivery, within 24 h of the previously scheduled in person session, and two working days after the end of face-to-face teaching at the authors’ institution. To ensure teaching continuity for students, and address intended learning outcomes (ILOs) where possible, we created online material rapidly in a manner familiar to students. Online material followed the same structure as a previously released laboratory script, intended for the in person session, and was presented on the institutional Virtual Learning Environment. The online material comprised experimental data in tables and equipment readouts, brief descriptions, and short videos demonstrating the experimental methods. We assess to what extent the ILOs were met, and argue that clear ILOs help guide changes to teaching methods, to reduce any disruption to student learning. Four aspects of the initiative are highlighted: rapid delivery; familiar structure; familiar delivery; and videos used for emphasis.

Published: September 2020

AbstractThe assemblage of water/watery/watering is a lively cartography of how water may be accounted for when theorising with and through environmental education research. Challenging the universalising claims of Western technoscience and the colonial logic of extraction, the article develops an alternative theoretical mapping of environmental education through engagements with Ingold’s (2007, 2012, 2015) concepts of lines, knots, and knotting. For this article and for the Special Issue in which it is housed, the concepts of such knottings are defined as an assemblage of haecceities, lived events that are looped, tethered and entangled as material and conceptual agencies that inhere within situated encounters. Thus, this article grapples with the need to account for water differently in contemporary posthuman ecologies. To overcome anthropocentric and mastery-oriented approaches, various other ways to account for water in science or environmental education will continue to come to the surface, bubbling and rushing like a waterfall as they have done in this work. Some of these will include thinking with water, which will be central to a theoretical mapping of water that seeks embrace sticky knots. The article explores a (re)turn to artful practices and encounters as spaces in which posthumanist concepts for environmental education might be cultivated.
The oldest bifoliate cystoporate and two other bryozoan taxa from the Dapingian (Middle Ordovician) of north-western Russia
Authors: Koromyslova Anna V. , Fedorov Petr V. 
Published: September 2020

AbstractBryozoans from the Dapingian (Middle Ordovician) of the Baltic paleobasin remain poorly studied and their taxonomic composition is unclear. In this paper, three bryozoan taxa, a bifoliate cystoporatePlanopora volkhovensisn. gen. n. sp., a trepostomeHemiphragma insolitumn. sp., and an esthonioporateEsthoniopora claraKoromyslova, are described from Dapingian deposits of an unusual clayey-calcareous Hecker-type mudmound on the right bank of the Volkhov River in Leningrad Oblast’, north-western Russia. Combined X-ray microtomography, scanning electron microscopy, and light microscopy of thin sections were used to characterize their morphology. Analysis of the stratigraphic distribution of early cystoporate bryozoans suggests thatPlanoporan. gen. is the oldest сystoporate bryozoan with an erect, bifoliate colony. The growth modes of these bryozoans are discussed. The colonies ofP.volkhovensisn. gen. n. sp. andE.clarahave an attachment structure, a holdfast, at their base, probably indicating their attachment to sponge spicules. The bryozoanH.insolitumn. sp. produced rod-like colonies, formed by overgrowing the problematic tubular fossilSphenothallusHall. It can be assumed that sponges with unfused siliceous spicules and individuals ofSphenothalluswere numerous on the surface of the mudmound during its formation and provided a suitable substrate for settlement of bryozoan larvae.UUID:http://zoobank.org/5715872a-8c61-446e-9413-d713fdef1a08

AbstractBackgroundAssociations of socioenvironmental features like urbanicity and neighborhood deprivation with psychosis are well-established. An enduring question, however, is whether these associations are causal. Genetic confounding could occur due to downward mobility of individuals at high genetic risk for psychiatric problems into disadvantaged environments.MethodsWe examined correlations of five indices of genetic risk [polygenic risk scores (PRS) for schizophrenia and depression, maternal psychotic symptoms, family psychiatric history, and zygosity-based latent genetic risk] with multiple area-, neighborhood-, and family-level risks during upbringing. Data were from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of 2232 British twins born in 1994–1995 and followed to age 18 (93% retention). Socioenvironmental risks included urbanicity, air pollution, neighborhood deprivation, neighborhood crime, neighborhood disorder, social cohesion, residential mobility, family poverty, and a cumulative environmental risk scale. At age 18, participants were privately interviewed about psychotic experiences.ResultsHigher genetic risk on all indices was associated with riskier environments during upbringing. For example, participants with higher schizophrenia PRS (OR = 1.19, 95% CI = 1.06–1.33), depression PRS (OR = 1.20, 95% CI = 1.08–1.34), family history (OR = 1.25, 95% CI = 1.11–1.40), and latent genetic risk (OR = 1.21, 95% CI = 1.07–1.38) had accumulated more socioenvironmental risks for schizophrenia by age 18. However, associations between socioenvironmental risks and psychotic experiences mostly remained significant after covariate adjustment for genetic risk.ConclusionGenetic risk is correlated with socioenvironmental risk for schizophrenia during upbringing, but the associations between socioenvironmental risk and adolescent psychotic experiences appear, at present, to exist above and beyond this gene-environment correlation.
Radiofrequency catheter ablation for supraventricular tachycardia in a paediatric population: characteristics of tachycardia mechanisms in a subpopulation with early onset
Authors: Schibli Yamina , Gass Matthias , Berger Florian , Balmer Christian 
Published: September 2020

AbstractBackground:In children, the first episode of supraventricular tachycardia occurs at various ages. The aim of this study is to describe age-specific tachycardia mechanisms, clinical findings, and outcome in a contemporary cohort of paediatric patients with supraventricular tachycardia.Methods:Retrospective analysis of 531 consecutive patients with structurally normal hearts under the age of 18 years who underwent invasive electrophysiological study for supraventricular tachycardia. The study population was divided into two groups, early-onset group (n = 57) and late-onset group (n = 474), according to the age of the occurrence of the first tachycardia before or after the age of 12 months.Results:Accessory pathway-mediated tachycardia was more common (82.5 versus 50.1%, p < 0.001) and the proportion of left-sided accessory pathways was more pronounced (74.5 versus 53.7%, p = 0.01) in the early-onset group than in the late-onset group. The antegrade and retrograde refractory periods of the accessory pathways were similar in both groups, but pre-excitation was more common in the early-onset group (50.9 versus 31.9%, p = 0.007). Typical atrioventricular nodal re-entrant tachycardia was more common (36.7 versus 7.0%, p < 0.001) in the late-onset group. There was no difference among the two groups regarding overall outcome.Conclusion:Accessory pathway-mediated re-entrant tachycardia is the most common mechanism of recurrent supraventricular tachycardia in infants with structurally normal hearts who are later referred to an electrophysiological study. These pathways often cause pre-excitation and tend to be located on the left side whereas their refractory period is not different from that of patients with late-onset tachycardia.

Published: September 2020

AbstractAim:This study reveals the characteristic nature and the use of optically stimulated luminescence dosimeters (OSLD) as an in vivo dosimetry tool for head and neck intensity-modulated radiation therapy (IMRT).Materials and methods:Calibration and characterisation of OSLD such as sensitivity, reproducibility, dose-rate dependence, beam quality dependence, output factor measurement and comparison of two bleaching techniques using halogen and compact fluorescent lamp (CFL) were initially performed. Later, eye dose measurements were performed for head and neck IMRT patients using OSLD and were compared with the corresponding dose calculated by the treatment planning system (TPS).Results:While the sensitivity was found to be within ±5%, the dose-rate dependence and reproducibility were found to be within ±3%. The OSLD showed an under-response of 3% for 15 MV and an increase in response by 5% for Co60 (1·25 MeV) when compared with the 6 MV X-ray beam. Therefore, a separate calibration for different beam energies is required. The percentage deviation of OSLD to that of TPS was found to be within ±2·77%. The OSLD has been successfully used for the in vivo dosimetry of patients who received IMRT. Hence, it is concluded that OSLDs can serve as effective dosimeters for in vivo dosimetry.
Bullous pemphigoid development during the course of breast cancer: a radiation induced or a radiation recall dermatitis?
Authors: Ben Rejeb Mouna , Moujahed Rim , Zehani Alia , Kochbati Lotfi 
Published: September 2020

AbstractBackground:Bullous pemphigoid (BP) is the most common autoimmune bullous disease, which is usually seen in older ages. Rarely, radiotherapy (RT) has been reported as a localised trigger factor for BP.Case:We present a case of a 64-year-old woman who underwent radical mastectomy and radiation therapy for breast cancer. Two months after the completion of RT with adjuvant Trastuzumab, a BP eruption developed in the irradiated area, spreading thereafter to other skin areas. The patient was treated with oral corticosteroids and the lesions evolved favourably.Conclusion:This case demonstrates a relatively benign skin reaction that could develop during the course of cancer treatment, which required co-management by oncologists, pathologists and dermatologists.
Extended formulation in cognitive behavioural therapy for OCD: a single case experimental design
Authors: Chatburn Eleanor , Millar Josie , Ryan Joachim 
Published: September 2020

Abstract
The demanding nature of exposure work that forms an essential component of exposure and response prevention (ERP) for obsessive compulsive disorder (OCD) is for some patients intolerable and leads to disengagement. The addition of cognitive therapy to ERP (CBT) with a focus on developing a shared understanding of how OCD works may aid engagement. This paper reports a case study of an individual who had not responded to two previous courses of ERP due to engagement difficulties with the treatment rationale. This study aimed to establish if CBT for OCD, incorporating an extended period of assessment and longitudinal formulation, would: (1) aid in engagement with the treatment rationale and therapy and (2) lead to an improvement in OCD symptoms, general functioning and mood. An A–B single case experimental design was used. Standardised measures were collected at weekly intervals over 15 sessions of CBT, in conjunction with pre–post idiographic behavioural measures. The extended formulation was successful in helping the individual to develop a less threatening understanding of how OCD works, enabling her to engage in therapy. This led to a reduction in the duration of the overt compulsions in her behavioural measures although on the standardised measures there was no change in self-reported OCD symptoms. The patient’s covert rituals and underlying responsibility and control beliefs largely remained intact, thus maintaining her OCD and requiring further intervention. There was a significant improvement in social functioning and consequently the patient reported being able to regain a sense of some control in her life.

Key learning aims

(1)
To describe the factors that might lead to a patient disengaging from exposure work in treatment for OCD.

(2)
To identify the advantages and disadvantages of incorporating a period of extended formulation when working with patients who have not previously been able to tolerate exposure work.

(3)
To describe ways of monitoring observable improvements in areas of functioning that matter to the patient in order to help them to celebrate their progress and boost their sense of self-efficacy.
