Published: September 2022

AbstractLocally available apricot (Prunus armeniaca L.) seed shell wastes were utilized for the preparation of an efficient dye biosorbent. The as-prepared apricot seed shell powder (ASP) was thoroughly characterized using FTIR, SEM-EDX, XRD, BET surface area, and pHPZC measurements to elucidate its functional groups, as well as its surface texture morphology and charge. The effect of several process variables (such as contact time, biosorbent dosage, pH, temperature, and initial concentration) on the dye uptake capacity was also investigated. Based on the experimental finding, the following optimum process conditions were established in the study: pH 2.0, 0.2 g/L adsorbent mass, 30 °C, and time of 120 min. The BET surface area, pore volume, and average pore size of the ASP were estimated as 97.493 m2/g, 0.0691 cm3/g, and 1.922 nm, respectively. The experimental equilibrium and kinetic data were properly described by the Temkin isotherm and pseudo-first-order kinetics model, respectively. Therefore, the effectiveness of ASP as an acid blue 193 dye biosorbent was established in the study.

Published: September 2022

AbstractPatients recovering from COVID-19 often report symptoms of exhaustion, fatigue and dyspnoea and present with exercise intolerance persisting for months post-infection. Numerous studies investigated these sequelae and their possible underlying mechanisms using cardiopulmonary exercise testing. We aimed to provide an in-depth discussion as well as an overview of the contribution of selected organ systems to exercise intolerance based on the Wasserman gears. The gears represent the pulmonary system, cardiovascular system, and periphery/musculature and mitochondria. Thirty-two studies that examined adult patients post-COVID-19 via cardiopulmonary exercise testing were included. In 22 of 26 studies reporting cardiorespiratory fitness (herein defined as peak oxygen uptake—VO2peak), VO2peak was < 90% of predicted value in patients. VO2peak was notably below normal even in the long-term. Given the available evidence, the contribution of respiratory function to low VO2peak seems to be only minor except for lung diffusion capacity. The prevalence of low lung diffusion capacity was high in the included studies. The cardiovascular system might contribute to low VO2peak via subnormal cardiac output due to chronotropic incompetence and reduced stroke volume, especially in the first months post-infection. Chronotropic incompetence was similarly present in the moderate- and long-term follow-up. However, contrary findings exist. Peripheral factors such as muscle mass, strength and perfusion, mitochondrial function, or arteriovenous oxygen difference may also contribute to low VO2peak. More data are required, however. The findings of this review do not support deconditioning as the primary mechanism of low VO2peak post-COVID-19. Post-COVID-19 sequelae are multifaceted and require individual diagnosis and treatment.
The Courage to Care: Teacher Compassion Predicts More Positive Attitudes Toward Trauma-Informed Practice
Authors: O’Toole Catriona , Dobutowitsch Mira 
Published: September 2022

Abstract
Purpose
With greater awareness of the prevalence and impact of childhood trauma and adversity, teachers are now assuming a more active role in creating emotionally healthy environments and responding to student distress. However, supporting trauma-affected students can be a source of amplified teacher stress. Compassion has been identified as a promising construct for frontline professionals in terms of promoting psychological wellbeing, and increasing the sensitivity to detect, tolerate and respond to distress in others. It has also been identified as an important aspect of trauma-informed practice. Nevertheless, the role of compassion in teachers’ attitudes towards, and readiness for implementing trauma-informed practices has not yet been explored. This study aimed to address this gap.

Methods
A sample of 377 primary and post-primary teachers in Ireland completed the Attitudes Related to Trauma-Informed Care Scale, the Professional Quality of Life Scale, the Self-Compassion Scale, and a socio-demographic survey.

Results
Teachers were found to hold generally positive attitudes toward trauma-informed care. They exhibited low to moderate levels of secondary traumatic stress and burnout, and notably high levels of compassion satisfaction, indicating that they tend to embrace their caring role and find meaning and purpose in their work. Regression analyses showed that compassion satisfaction was the strongest predictor of positive attitudes toward trauma-informed care, followed by self-compassion. Older teachers were more likely to display positive attitudes toward trauma-informed care, whilst teachers in single-sex boys’ schools held attitudes that were less favorable.

Conclusion
This study suggests potential benefits for both teachers and students of positioning compassion at the center of educational policy and practice. The results are contextualized within the Irish and international educational landscape.

Published: September 2022

AbstractEpoxy-based nanocomposites can be ideal electromagnetic interference (EMI)-shielding materials owing to their lightness, chemical inertness, and mechanical durability. However, poor conductivity and brittleness of the epoxy resin are challenges for fast-growing portable and flexible EMI-shielding applications, such as smart wristband, medical cloth, aerospace, and military equipment. In this study, we explored hybrid nanofillers of single-walled carbon nanotubes (SWCNT)/reduced graphene oxide (rGO) as conductive inks and polyester fabrics (PFs) as a substrate for flexible EMI-shielding composites. The highest electrical conductivity and fracture toughness of the SWCNT/rGO/PF/epoxy composites were 30.2 S m−1 and 38.5 MPa m1/2, which are ~ 270 and 65% enhancement over those of the composites without SWCNTs, respectively. Excellent mechanical durability was demonstrated by stable electrical conductivity retention during 1000 cycles of bending test. An EMI-shielding effectiveness of ~ 41 dB in the X-band frequency of 8.2–12.4 GHz with a thickness of 0.6 mm was obtained with an EM absorption-dominant behavior over a 0.7 absorption coefficient. These results are attributed to the hierarchical architecture of the macroscale PF skeleton and nanoscale SWCNT/rGO networks, leading to superior EMI-shielding performance. We believe that this approach provides highly flexible and robust EMI-shielding composites for next-generation wearable electronic devices.

Published: September 2022

AbstractRational construction of flexible free-standing electrocatalysts featuring long-lasting durability, high efficiency, and wide temperature tolerance under harsh practical operations are fundamentally significant for commercial zinc–air batteries. Here, 3D flexible free-standing bifunctional membrane electrocatalysts composed of covalently cross-linked supramolecular polymer networks with nitrogen-deficient carbon nitride nanotubes are fabricated (referred to as PEMAC@NDCN) by a facile self-templated approach. PEMAC@NDCN demonstrates the lowest reversible oxygen bifunctional activity of 0.61 V with exceptional long-lasting durability, which outperforms those of commercial Pt/C and RuO2. Theoretical calculations and control experiments reveal the boosted electron transfer, electrolyte mass/ion transports, and abundant active surface site preferences. Moreover, the constructed alkaline Zn–air battery with PEMAC@NDCN air–cathode reveals superb power density, capacity, and discharge–charge cycling stability (over 2160 cycles) compared to the reference Pt/C + RuO2. Solid-state Zn–air batteries enable a high power density of 211 mW cm−2, energy density of 1056 Wh kg−1, stable charge–discharge cycling of 2580 cycles for 50 mA cm−2, and wide temperature tolerance from − 40 to 70 °C with retention of 86% capacity compared to room-temperature counterparts, illustrating prospects over harsh operations.

Published: September 2022

AbstractCatalysis has been regarded as an effective strategy to mitigate sluggish reaction kinetics and serious shuttle effect of Li–S batteries. Herein, a spherical structure consists of ultrathin layered Ti3C2Tx-TiN heterostructures (MX-TiN) through in-situ nitridation method is reported. Through controllable nitridation, highly conductive TiN layer grew on the surface and close coupled with interior MXene to form unique 2D heterostructures. The ultrathin heterostructure with only several nanometers in thickness enables outstanding ability to shorten electrons diffusion distance during electrochemical reactions and enlarge active surface with abundant adsorptive and catalytic sites. Moreover, the (001) surface of TiN is dominated by metallic Ti–3d states, which ensures fast transmitting electrons from high conductive MX-TiN matrix and thus guarantees efficient catalytic performance. Calculations and experiments demonstrate that polysulfides are strongly immobilized on MX-TiN, meanwhile the bidirectional reaction kinetics are catalytically enhanced by reducing the conversion barrier between liquid LiPSs and solid Li2S2/Li2S. As a result, the S/MX-TiN cathode achieves excellent long-term cyclability with extremely low-capacity fading rate of 0.022% over 1000 cycles and remarkable areal capacity of 8.27 mAh cm−2 at high sulfur loading and lean electrolytes.

Examining Nonlinear Effects of Crafting Social Resources on Work Engagement – the Moderating Role of Exhaustion
Authors: Lopper Elisa , Dettmers Jan , Hoppe Annekatrin 
Published: September 2022

AbstractCrafting social resources is a job crafting strategy that implies changing one’s social job resources to improve person-job fit and work-related well-being. Previous research has mostly assumed a resource-generating nature of crafting social resources and investigated the linear positive effects of this job crafting strategy on, for example, work engagement. Considering that crafting social resources can also be resource-consuming, in this paper, we referred to conservation of resources theory and resource allocation theory and proposed a curvilinear, U-shaped relationship between crafting social resources and work engagement. We further predicted that exhaustion would moderate this curvilinear relationship. To test our hypotheses, a two-wave study with 233 employees was conducted. Consistent with our assumptions, compared with a low or high level, a moderate (i.e., occasional) level of crafting social job resources was associated with a lower level of work engagement three months later. Furthermore, exhaustion acted as a moderator insomuch that a low level of exhaustion mitigated the detrimental effect of crafting social resources at a moderate level on work engagement. Accordingly, the findings showed that crafting social resources is not always beneficial and can impair employees’ work engagement, especially for exhausted employees.
Iliac Artery Tortuosity, Calcification and Abnormal Shape Augment Aortic Aneurysm Anatomy in Predicting Complications After Endovascular Aneurysm Repair

Published: September 2022

Abstract
Post-surgical complications following endovascular aneurysm repair (EVAR) remain a risk, arising from technical difficulties imposed by highly calcified or tortuous iliac arteries. Automated methods enable segmentation of the iliac artery to potentially better define perioperative risk prediction. This study uses imaging software to characterise segmental iliac artery anatomy and aims to establish if iliac artery abnormalities can predict adverse outcomes following EVAR. Pre-operative clinical information and CT angiograms were obtained from 189 patients who underwent elective EVAR. Patients were followed for up to 3 years to detect stent-related complications and mortality. Aneurysm morphology was manually measured on CT scans. Automated measurements of vessel shape, curvature and calcification were taken for multiple subdivisions of the common and external iliac arteries. Logistic regression models were trained to assess the influence of iliac artery and aneurysm morphology on outcomes. Combining iliac and aortic features improved predictions of both stent-related complications and morbidity over using either alone. Models predicting death and both early and late stent complications had respective areas under the curve (AUCs) of 0.761, 0.935 and 0.833. Iliac artery calcification and curvature were significant predictors of poor outcomes. Automated morphological assessment of the common and external iliac artery improves the prediction of complications following EVAR. The improved power of iliac morphology to predict late complications and death implies that regional abnormalities of the iliac arteries are important when assessing surgical risk. This allows further rationalisation of the selection of individuals for treatment and may improve patient outcomes.

Published: September 2022

Abstract
Coordinating complex crisis responses generally requires comprehensive skills. When operating in the High Arctic, extreme environments make this task even more challenging. Training for these situations is thus of utmost importance, but such training requires extensive resources for full-scale exercises. Simulation is an alternative that can yield an effective learning process and learning outcomes. In this study, we explored how simulator-based accident training in high-risk, highly sensitive environments can be optimised. To do this, Exercise Isfjord was designed for students in the master’s Preparedness and Emergency Management programme at NORDLAB at Nord University. This exercise involved a grounded cruise ship from which passengers needed to be evacuated, in addition to a severe oil spill. Interviews with students, mentors, facilitators, and academic staff were conducted, and thematic analysis was used for analysing the data. Our findings indicate that a pedagogical wheel consisting of the six factors preparations, psychological safety, mentors, learning objectives, context realism, and evaluations promotes an optimal learning process in simulated-accident exercises in high-risk and highly sensitive environments. Thus, we recommend tailor-made simulated exercises for crisis management and emergency preparedness.

AbstractIntroductionErectile dysfunction (ED) is very common in diabetic males, especially type 2 diabetes mellitus (T2DM). Many factors and complications of diabetes such as macro- and micro-angiopathy are associated with risks leading to ED in male patients.AimAnalysis of factors associated with ED in T2DM. The purpose of this study is to shed light on potential associations between ED, type 2 diabetes, and some risks factors.Material and methodsThis was a prospective analytic study of T2DM over 18. The study population consisted of diabetic patients seen at the endocrinology and urology departments of the University Hospital during the study period. Evaluation of ED was made by IIEF 5 score.OutcomesA total of 333 patients were selected for the study. The mean age was 56.6 ± 9.8 and the prevalence of ED was 82.6% (n = 275).ResultsIn univariate analysis, several associated factors were identified such as micro-angiopathic type complications including diabetic retinopathy (OR 4.88 [2.31–10.33], P &lt; .001), diabetic nephropathy (OR 12.67 [1.71–93.66], P = .002) and macro-angiopathic type including arterial hypertension (OR 3.12 [1.69–5.75], P &lt; .001). In multivariate analysis, duration of diabetes, micro and macroangiopathic complications, and hyperuricemia were independent risk factors for the occurrence of ED (P &lt; .05).Clinical ImplicationsThe presence of certain complications of diabetes such as micro or macro angiopathy or hyperuricemia should lead to a search for a ED. The presence of these associated factors identified in type 2 diabetic patients should systematically prompt an ED diagnosis which is often moderate or severe. That diagnosis would help design a protocol for the management and improvement of the life quality of these patients.Strengths and LimitationsThe strength of this work is that it was conducted in the biggest hospital in the country which gives us a good idea of the trend of this ailment in the country. But the limitation of the study is that it only included patients who visited the hospital. This is monocentric hospital study was also transversal which does allow to establish a causal link.ConclusionED has a significant prevalence in T2DM. Several associated factors identified in uni and multivariate analyses, including duration of diabetes, micro and macro angiopathic complications, and hyperuricemia, increase ED risk. Therefore, it is essential to investigate the existence of these factors to improve the management of ED, which may allow the patient to regain a better overall health status.

Abstract

Introduction
Lateral retroperitoneal adrenalectomy (LRPA) was introduced to a teaching hospital. A fixed operating team of experienced surgeons and a step-by-step educational approach were employed. Surgical outcomes during the study period are analyzed. The safety of this process was evaluated.

Methods
In this case series study, data for all patients who underwent LRPA from 2006 to 2020 were retrospectively reviewed. Patients were divided into two groups according to when surgery was performed, the introduction period, and the subsequent education period. All data were compared between the two groups. Three surgeons were certified as independent surgeons during the education period. The outcomes of procedures performed by these three surgeons as trainees were compared.

Results
A total of 179 patients underwent LRPA with 53 patients during the introduction period and 126 patients during the education period. There was no significant difference between the two groups regarding operating time (129min vs 134min, p = 0.63) or estimated blood loss (63 ml vs 43 ml, p = 0.36). There were no significant differences in conversion to other procedures or perioperative complications. Among the three surgeons certified as independent surgeons during the education period, there were no significant differences in operating time (140min vs 120min vs 149min, p = 0.056), estimated blood loss (31 ml vs 28 ml vs 42 ml, p = 0.874), conversion to other procedures, perioperative complication rate, or postoperative length of stay. There was no evidence of a learning curve effect.

Conclusion
LRPA as a new procedure was safely introduced to a teaching hospital and safely promulgated to trainees.

Prophylactic antibiotics and Postoperative Surgical Site Infections in cutaneous surgery: A systematic review and meta-analysis
Authors: Lalla Soogan C. , Bonadurer George F. , Murad Hassan M. , Brewer Jerry D. 
Published: September 2022

Abstract

Introduction
The risks and benefits of antibiotic prophylaxis (AP) in the setting of dermatologic surgery are unclear. This meta-analysis evaluated the effect of AP on the risk of SSIs and adverse events (AE) of AP in clean and clean/contaminated cutaneous surgical procedures.

Methods
Embase, MEDLINE, and Scopus databases were searched from inception through August 16, 2021. Two reviewers independently selected randomized controlled trials (RCTs) in which participants undergoing elective clean and clean/contaminated surgical procedures received either an identified course of AP, or no AP or a placebo.
Data extracted were surgery type, antibiotic and control interventions, occurrence of SSIs and adverse events (AEs). SSI risk was pooled across trials by using a random-effects model. Certainty of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation approach.

Results
Twenty-eight RCTs (12,958 surgical wounds in 12,698 participants) were included. Postoperative SSIs were reduced in the AP group compared with controls (3.4% vs 7.4%; incidence rate ratio [IRR], 0.48 [95% CI, 0.37–0.62]; high certainty of evidence). Subgroup analysis showed a reduction in SSI risk for Mohs micrographic surgery (IRR, 0.22 [95% CI, 0.09–0.51]), dermatologic surgery (IRR, 0.29 [95% CI, 0.14–0.60]), and plastic or breast surgery (IRR, 0.60 [95% CI, 0.45–0.80]). Risk of AEs was not different between AP and control groups.

Conclusion
AP reduces SSI risk in clean and clean/contaminated cutaneous surgical procedures. The benefits of AP should be balanced against costs, drug interactions, antibiotic resistance, and surgical sites or procedures that are associated with a lower likelihood of infection.

Abstract

Introduction
The purpose of robot-assisted TKA is to improve implant positioning and soft tissue management, and thus improve the clinical results and implant survivorship. This study compared short-term outcomes of an imageless robot-assisted TKA versus conventional TKA. Imageless robot-assisted TKA would demonstrate improved short-term outcomes, in comparison with conventional TKA.

Methods
In this retrospective cohort study, we compared demographic, intraoperative, and postoperative data of 150 imageless robot-assisted TKA patients and 150 conventional TKA patients.

Results
Imageless robot-assisted TKA patients had reduced pain scores on day one following the surgery and had shorter postoperative length of stay (LOS). In contrast, there was no difference between the groups in the frequency of post-surgical infection or revision TKA. In addition, no difference was found in the duration of surgery.

Conclusion
It seems that the imageless robot-assisted TKA leads to similar short-term outcomes, compared with conventional TKA, with a few advantages over the latter, such as reduced pain scores on day one following the surgery and shorter LOS, without prolonging the surgery duration. Further investigation is needed to explore whether these findings have long-term clinical significance.

Level of evidence
