Tribological Investigations of Two-Dimensional Nanostructured Lamellar Materials as Additives to Castor-Oil-Derived Lithium Grease
Authors: Rawat Sooraj Singh , Harsha A. P. , Khatri Om P. 
Published: March 2022

Abstract
The present work deals with the tribological evaluation of castor-oil-derived lithium grease having variable concentrations of pristine and chemically functionalized MoS2 and graphene nanosheets. The MoS2 and graphene oxide nanosheets were synthesized by hydrothermal and Hummer's method, respectively. The tribological performance of castor grease with and without two-dimensional (2D) lamellar nanomaterials was evaluated using a four-ball tribo-tester as per ASTM standards. The graphene-based lamellar nanomaterials in castor grease significantly improved the tribological properties by decreasing friction and wear. The optimized concentration of MoS2-ODT, MoS2, GO-ODA, GO, and rGO nanomaterials in castor grease conserved the frictional energy losses by 19%, 34%, 35%, 54%, and 56%, respectively. Among all samples, the rGO nanosheets in castor grease showed a maximum reduction in friction and wear. The spectroscopic analysis of worn surfaces suggested the establishment of graphene-based tribo-film, which reduced the direct interaction of tribo-interfaces and minimized the friction and wear.

Published: March 2022

Coaches are among the most important agents for young football talents’ development. Their coaching style may impact not only players’ skill acquisition but also their motivation to meet their full potential. This study begins by presenting an intervention promoting need-supportive coaching to facilitate holistic talent development within the German Football Association (Deutscher Fußball-Bund [DFB]). The intervention was grounded in Deci and Ryan’s self-determination theory and designed as a hybrid model of coach education (i.e., online and in-present elements). In addition, DFB competence center coordinators were utilized as multipliers to reach a large population of approximately 1,300 coaches across Germany. The specific aim of this paper is to examine how these coordinators experienced the development and implementation process of the intervention. Utilizing a mixed-methods approach, coordinators’ satisfaction and experiences with the intervention were evaluated via a quantitative online survey (n = 23) and qualitative follow-up interviews (n = 8). Overall, the findings suggest that the presented approach may be suitable to address potential barriers in coach education, such as gaining coaches’ buy-in, transferring scientific knowledge into practice, and supporting long-term behavioral modifications in coaches. Specific recommendations (e.g., knowledge translation, gaining buy-in) for designing future interventions are highlighted.
Representatives of the Miaohe Biota from the Ediacaran (Vendian) Pre-Shuram Strata of the Patom Highland, Siberia
Authors: Petrov P. Yu. , Vorob’eva N. G. 
Published: March 2022

Abstract
The carbonaceous macrofossils which belong to multicellular algae and which were previously known from the younger (>570 Ma) Miaohe biota are found for the first time in the Lower Vendian (Middle Ediacaran, ~580 Ma) rocks of the Ura Formation of the Patom Basin in Siberia. The Ura macrofossils include phytoleims of unbranched ribbon-like thalli preserved on the surfaces of silty mudstones. Among the fossils, the species Liulingjitaenia alloplecta and Jiuqunaoella simplicis are identified. The features of their structure are considered. The in vivo forms of the organisms and their colonies are interpreted. It is shown that these organic macrofossils were a noticeable detritus-forming component of the Ura Basin. The Ura macrophytes coexisted with the Early Ediacaran microbiota and composed a common ecosystem of the paleobasin, which formed shortly before the Shuram event and was significantly transformed after it.
Food handling practice and associated factors among food handlers in public food establishments of Ethiopia: a systematic review and meta-analysis
Authors: Tadele Maru Meseret , Dagnaw Amare , Alamirew Dehabo 
Published: March 2022

ObjectivesFood handlers are individuals who are involved in food preparation, storage or service of food in a food facility. Unless they keep their personal hygiene, they are highly responsible for contaminating food or transmitting microbes to consumers. Thus, the main aim of this review was to pool the level of good food handling practice among food handlers working in public food establishments in Ethiopia.DesignA systematic review and meta-analysis using the Joanna Briggs Institute (JBI) Critical Appraisal tool.Data sourcesPubMed, Google Scholar and Advanced Google were searched up to the end of February 2021.Eligibility criteria for selecting studiesPublication status, publication language, type of study participants and the type of article were used to screen the article.Data extraction and study quality assessmentAll reviewers collected data independently and merged them together. A tool called the JBI Meta-Analysis of Statistics Assessment and Review Instrument was used to assess the quality of each research article. The assessment was performed by two reviewers.ResultA total of 16 research articles were included in the review. The pooled level of good food handling practice was 50.72% with 95% CI (43.84% to 57.6%). Training (adjusted OR (AOR)=3.4, 95% CI (2.33 to 4.95)), attitude (AOR=3.62, 95% CI (2.23 to 5.85)) and medical check-up (AOR=5.12, 95% CI (2.93 to 8.95)) were identified as factors affecting good food handling practice with 95% CI at p<0.05.ConclusionThe level of good food handling practice among food handlers working in public food establishments of Ethiopia was very low compared with literature, and variables such as food handler training, attitude towards good food handling practice and the existence of regular medical check-ups were factors affecting good food handling practice. Provision of training that could change the attitude and regular medical check-ups for food handlers has to be in place.

Published: March 2022

IntroductionLow birth weight (LBW) is associated with a wide range of short-term and long-term consequences and is related to maternal psychosocial and behavioural determinants. The objective of this study is to estimate the effect of implementing fast-track referral for early intervention on psychosocial and behavioural risk factors—smoking, alcohol consumption, depression and physical violence—in reducing the incidence of LBW.Methods and analysisParallel superiority pragmatic clinical trial randomised by clusters. Primary healthcare units (PHCU) located in Portugal will be randomised (1:1) to intervention or control groups. Pregnant women over 18 years of age attending these PHCU will be eligible to the study. Risk factors will be assessed through face-to-face interviews. In the intervention group, women who report at least one risk factor will have immediate access to referral services. The comparison group will be the local standard of care for these risk factors. We will use intention-to-treat analyses to compare intervention and control groups. We estimated a sample size of 2832 pregnant women to detect a 30% reduction in the incidence rate of LBW between the control and intervention groups. Secondary outcomes are the reduction of preterm births, reduction of the four risk factors and acceptance of the intervention.Ethics and disseminationThe study was approved by the Ethics Committee of the Public Health Institute of the University of Porto (no CE20140). The findings will be disseminated to the public, the funders, health professionals, health managers and other researchers.Trial registration numberNCT04866277.
Using stakeholders’ experiences to redesign health services for persons living with heart failure: a case study protocol in a Swedish cardiac care setting
Authors: Suutari Anne-Marie , Nordin Annika , Kjellström Sofia , Thor Johan , Areskoug Josefsson Kristina 
Published: March 2022

IntroductionClinical guidelines promote recognising persons with heart failure (referred to as PWHF) as coproducers of their own care. Coproduction of healthcare—involving PWHF, families and professionals in care processes—aims to promote the best possible health. Still, it is unclear how to coproduce heart failure (HF) care. This study explores whether and how Experience-Based Co-Design (EBCD) involving PWHF, family members and professionals can be undertaken online, in a Swedish cardiac care setting, to codesign improved experiences of HF care.Methods and analysisIn EBCD, stakeholders’ experiences are solicited to redesign healthcare services. First, we will undertake a thematic analysis of field notes from consultations and filmed/audio-recorded interviews with PWHF (n=10–12). This analysis will identify ‘touchpoints’ (emotionally positive/negative events that shape overall service experiences), edited into a ‘trigger film’. Next, a thematic analysis of family members’ (n=10–12) and professionals’ (n=10–12) interviews will identify key themes mirroring their experiences. Separate feedback events with each stakeholder group will confirm identified touchpoints and key themes and identify areas for HF care improvement. At a joint event, prompted by the ‘trigger film’, stakeholders will agree on one area for HF care improvement. A team including PWHF, family members and professionals, led by an improvement adviser, will then plan, design, implement and evaluate an improvement activity addressing the identified problem area. A deductive thematic analysis of field notes, project documentation and stakeholder focus group interviews, underpinned byMUSIQ, will identify how organisational conditions influence the process. Quantitative measurements, describing the results of the improvement activity, will be integrated with qualitative data to strengthen the case. To reduce resource intensity, we will use online tools during the process.Ethics and disseminationThe Swedish Ethical Review Authority approved the study in May 2021. The results will be disseminated through seminars, conference presentations and publications.

Published: March 2022

ObjectiveTo summarise available chronic kidney disease (CKD) diagnostic and prognostic models in low-income and middle-income countries (LMICs).MethodSystematic review (Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines). We searched Medline, EMBASE, Global Health (these three through OVID), Scopus and Web of Science from inception to 9 April 2021, 17 April 2021 and 18 April 2021, respectively. We first screened titles and abstracts, and then studied in detail the selected reports; both phases were conducted by two reviewers independently. We followed the CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies recommendations and used the Prediction model Risk Of Bias ASsessment Tool for risk of bias assessment.ResultsThe search retrieved 14 845 results, 11 reports were studied in detail and 9 (n=61 134) were included in the qualitative analysis. The proportion of women in the study population varied between 24.5% and 76.6%, and the mean age ranged between 41.8 and 57.7 years. Prevalence of undiagnosed CKD ranged between 1.1% and 29.7%. Age, diabetes mellitus and sex were the most common predictors in the diagnostic and prognostic models. Outcome definition varied greatly, mostly consisting of urinary albumin-to-creatinine ratio and estimated glomerular filtration rate. The highest performance metric was the negative predictive value. All studies exhibited high risk of bias, and some had methodological limitations.ConclusionThere is no strong evidence to support the use of a CKD diagnostic or prognostic model throughout LMIC. The development, validation and implementation of risk scores must be a research and public health priority in LMIC to enhance CKD screening to improve timely diagnosis.

Published: March 2022

BackgroundMaintaining quality of life is a primary goal of palliative care (PC). Complementary interventions can help meet the needs of patients at the end of life.ObjectivesThis meta-analysis aims to (1) evaluate the feasibility, acceptability and fidelity of music and hypnosis interventions designed for patients in PC and (2) evaluate the impact of these interventions on pain, anxiety, sleep and well-being.MethodsRelevant studies were sourced from major databases. We selected both randomised controlled trials (RCTs) and studies relying on pre–post design with details of the intervention(s).ResultsFour RCT and seven non-randomised pre–post studies met the inclusion criteria. Overall, the feasibility and acceptability of the interventions reached an adequate level of satisfaction. However, only three studies reported using a written protocol. The meta-analysis of RCT indicated a significant decrease in pain with an effect size of −0.42, p=0.003. The small number of RCT studies did not allow us to quantify the effects for other variables. Analyses of data from pre–post designs indicated a favourable outcome for pain, anxiety, sleep and well-being.ConclusionDespite the limited number of studies included in our meta-analysis, hypnosis and music intervention in the context of PC shows promising results in terms of feasibility and acceptability, as well as improvements on pain, anxiety, sleep and well-being. The available studies are insufficient to compare the efficacy across interventions and assess the potential benefits of their combinations. These results underscore the importance of further research on well-described complementary interventions relying on hypnosis and music.PROSPERO registration numberCRD-42021236610.
Hyperbolic disc embedding of functional human brain connectomes using resting-state fMRI

Published: March 2022

Abstract
The brain presents a real complex network of modular, small-world, and hierarchical nature, which are features of non-Euclidean geometry. Using resting-state functional magnetic resonance imaging, we constructed a scale-free binary graph for each subject, using internodal time series correlation of regions of interest as a proximity measure. The resulting network could be embedded onto manifolds of various curvatures and dimensions. While maintaining the fidelity of embedding (low distortion, high mean average precision), functional brain networks were found to be best represented in the hyperbolic disc. Using the 𝕊1/ℍ2 model, we reduced the dimension of the network into two-dimensional hyperbolic space and were able to efficiently visualize the internodal connections of the brain, preserving proximity as distances and angles on the hyperbolic discs. Each individual disc revealed relevance with its anatomic counterpart and absence of center-spaced node. Using the hyperbolic distance on the 𝕊1/ℍ2 model, we could detect the anomaly of network in autism spectrum disorder subjects. This procedure of embedding grants us a reliable new framework for studying functional brain networks and the possibility of detecting anomalies of the network in the hyperbolic disc on an individual scale.
Concessive Knowledge Attributions Cannot Be Explained Pragmatically
Authors: Stoutenburg Gregory 
Published: March 2022

Abstract
“I know that p but it is possible that not-p” sounds contradictory. Some philosophers, notably David Lewis, have taken this as evidence that knowledge requires infallibility. Others have attempted to undermine that inference by arguing that there is a plausible pragmatic explanation of why such sentences sound odd, and thus do not undermine fallibilism. I argue that the proffered pragmatic explanations fail and I raise challenges for any possible pragmatic explanation of the character of concessive knowledge attributions. It is reasonable to conclude that concessive knowledge attributions are genuine contradictions.

Published: March 2022

The Australian Orchesellidae includes only 11 nominal species in four genera: Australotomurus Stach, 1947, Alloscopus Börner, 1906, Heteromurus Wankel, 1860, and Falcomurus Mandal, 2018. Here we describe Dicranocentrus dolosus sp. nov. from Cocos and Keeling Islands, the first species of the genus to be recorded from Australia. The new species is similar to D. inermodentes (Uchida, 1944) and D. indicus Bonet, 1930, but differs from both by the combination of the ventral head, mesothoracic and dental chaetotaxy. We also revisit Australotomurus based on previous studies to better interpret the dorsal macrochaetotaxy of the genus, and provide a synthetic map of chaetae to guide future studies on scaleless Orchesellidae. Finally, we present updated diagnoses to all genera and species of Australian Orchesellidae, as well as an identification key to all species.

Authors: Pierce Scott M. , Heiman Adee J. , Ricci Joseph A. 
Published: March 2022

Background The high rate of work-related musculoskeletal disorders (WMSD) among surgeons is well-documented and found to factor into medical students’ interest in surgical specialties. Ergonomic techniques can reduce musculoskeletal pain in surgeons. Access to ergonomics education in residency is minimal and the ergonomics education offered in medical school has not been characterized. Methods An anonymous, online survey was distributed to 210 administrators in medical education and curriculum at all accredited US allopathic medical schools. They were asked about their knowledge of ergonomics, assessment of potential benefits of ergonomics education to their students, and the ergonomics education offered at their institution. Results A total of 71 surveys were completed (33.8% response rate). 82% of schools reported familiarity with the study of ergonomics and 81% thought it would be beneficial to the future careers of their students to receive ergonomics education. Respondents estimated 43% of surgeons experience WMSDs and those that did not think ergonomics education would be beneficial to their students’ future careers had a statistically significantly lower estimate of WMSD burden amongst practicing surgeons. Only one respondent reported that students at their institution receive greater than three hours of ergonomics education, while 98% reported their students will receive less than three hours. Considering this, 81% of respondents reported that students do have access to other resources that encourage ergonomic practices, such as gym access, yoga classes, and surgical simulation labs. Discussion Medical schools should increase access to ergonomics education and integrate it into their curriculum as early as possible.

Background Problem-Based Learning (PBL) has become an integral part of medical student education for preclinical curricula, but few studies have evaluated the benefits of a PBL curriculum for clinical education. This study aims to assess the 1-year experience after implementing a resident-led PBL program for the third-year (MS3) surgery clerkship and compare students’ self-reported preparedness following PBL sessions to traditional faculty-led lectures. Methods Surgical faculty and residents developed a PBL curriculum to address common topics in surgical education. Pandemic requirements necessitated a switch from in-person to virtual sessions during the experience. Students enrolled in the MS3 surgical clerkship were asked to participate in a survey. Demographics and clerkship data were obtained. Quality of PBL and faculty-led lectures were assessed using a ten-point Likert scale, and standard statistical analyses were performed. Results During the study period, 165 students rotated through surgery, of which 129 (78%) responded to the survey (53% female, 59% white). PBLs were held in-person (53%), exclusively virtual (32%) or hybrid (15%) platforms. In-person PBLs were preferred to faculty-led lectures for preparing students for NBME examinations (6.9 vs 6.0), oral examinations (7.8 vs 6.3), and surgical cases (6.3 vs 5.8), all P < .001. Virtual PBLs were also preferred to lectures for preparing students for NBME examinations (6.8 vs 5.8, P < .001) and surgical cases (5.6 vs 4.8, P = .05). Conclusions PBL is a valuable adjunct for medical student education. Resident-led PBLs were preferred to faculty-led lectures for preparing students for examinations and clerkship experiences and may be useful adjuncts to clinical education.

Published: March 2022

Introduction Enhanced recovery after surgery protocols are commonly used, but their utility in patients with inflammatory bowel disease and steroid use is poorly studied. We sought to examine influence of inflammatory bowel disease (IBD) and steroid use on hospital length of stay (LOS) and operative duration in patients undergoing colectomies in the era of ERAS. Methods We performed retrospective review of our institutional National Surgical Quality Improvement Program (NSQIP) registry (2016-2018) for colectomies. We performed 2 distinct analyses to examine influence of steroids and IBD on LOS and operative duration. Multivariable linear regression was used to predict outcomes after adjusting for relevant perioperative features. Results There were 366 patients in the cohort; 17.8% were on steroids and 16.4% had IBD. Patients using steroids had longer LOS (6 vs 4 days, P < .0001). IBD patients had a longer LOS (7 vs 5 days, P < .0001) and longer operative duration (383 min vs 335.5 minute, P = .01) compared to non-IBD patients. On multivariable analysis, steroid use was not associated with increased LOS or operative duration. Inflammatory bowel disease was associated with an increased hospital LOS and operative duration. Discussion Patients on steroids had longer LOS when compared to patients not on steroids. Inflammatory bowel disease regardless of steroid use was found to be a significant risk factor for both increased LOS and operative duration. A closer look at preoperative physiology may help to tailor ERAS protocols in patients with inflammatory conditions.
