AbstractAimTo describe the state of health of Quebec nursing staff during the pandemic according to their exposure to COVID‐19, work‐related characteristics and sociodemographic factors (gender, generational age group). State of health was captured essentially by assessing psychological distress, depression symptoms and fatigue.Design and methodsA large‐scale cross‐sectional study was conducted with 1,708 nurses and licenced practical nurses in Quebec (87% women, mean age of 41 ± 11 years). The survey included several questionnaires and validated health‐related scales (psychological distress, depression symptoms and fatigue). The STROBE guidelines were followed in reporting the study's findings.ResultsResults showed that the prevalence of psychological distress and depression symptoms was moderate to severe. Women, generation Xers and Yers, nurses who cared for COVID‐19 patients and those with a colleague who was infected with COVID‐19 at work scored higher for fatigue, psychological distress and depression.
Can we remove tattoos with non‐thermal atmospheric plasma?
Authors: Tampieri Francesco , Araguz Ariadna G. , Canal Cristina 
Published: February 2022

AbstractCurrent methods for tattoo removal are long, costly and have drawbacks such as scarring among others. Looking for alternatives, here we assess the feasibility of non‐thermal plasma (NTP) as a standalone method for the removal of tattoos. We report the results of atmospheric pressure plasma jet treatment of real tattoo inks suspensions in water and in gelatin (liquid or as a solid film), selected as a model of skin. Analysis of the residual color and the temperature effect in all the samples after plasma treatment reveals significant differences between water and the skin model. Kinetic considerations and the extension of our results to more realistic scenarios allow us to conclude that NTP cannot compete with the current laser technology in a real application.

Published: February 2022

AbstractLow pressure capacitively coupled radiofrequency plasmas operated in a mixture of aniline vapor and argon are used for the deposition of thin films on silicon substrates. The influence of the aniline vapor fraction in the gas mixture upon the plasma properties and the characteristics of the deposited thin film is analyzed. Plasmas diagnostics are carried out using mass spectrometry and optical emission spectroscopy and the thin films are characterized by means of Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and near‐edge X‐ray absorption fine‐structure spectroscopy. Experiments highlight that the use of a low aniline/argon ratio leads to the deposition of an amorphous film whereas high‐aniline/argon ratios allow the synthesis of a plasma polymer similar to polyaniline. The properties of such plasmas and the mechanisms involved in the deposition process are discussed in detail.

Authors: Nazari Ali A. , Zareinia Kourosh , Janabi‐Sharifi Farrokh 
Published: February 2022

AbstractBackgroundRecent advancements in continuum robotics have accentuated developing efficient and stable controllers to handle shape deformation and compliance. The control of continuum robots (CRs) using physical sensors attached to the robot, particularly in confined spaces, is difficult due to their limited accuracy in three‐dimensional deflections and challenging localisation. Therefore, using non‐contact imaging sensors finds noticeable importance, particularly in medical scenarios. Accordingly, given the need for direct control of the robot tip and notable uncertainties in the kinematics and dynamics of CRs, many papers have focussed on the visual servoing (VS) of CRs in recent years.MethodsThe significance of this research towards safe human‐robot interaction has fuelled our survey on the previous methods, current challenges, and future opportunities.ResultsBeginning with actuation modalities and modelling approaches, the paper investigates VS methods in medical and non‐medical scenarios.ConclusionsFinally, challenges and prospects of VS for CRs are discussed, followed by concluding remarks.
Distributed dynamics for aggregative games: Robustness and privacy guarantees
Authors: Shakarami Mehran , De Persis Claudio , Monshizadeh Nima 
Published: February 2022

AbstractThis paper considers the problem of Nash equilibrium (NE) seeking in aggregative games, where the cost function of each player depends on an aggregate of all players' actions. We present a distributed continuous‐time algorithm such that the actions of the players converge to NE by communicating to each other through a connected network. As agents may deviate from their optimal strategies dictated by the NE seeking protocol, we investigate robustness of the proposed algorithm against time‐varying disturbances. In particular, we provide rigorous robustness guarantees by proving input‐to‐state stability (ISS) and ‐stability properties of the NE seeking dynamics. A major concern in communicative schemes among strategic agents is that their private information may be revealed to other agents or to a curious third party who can eavesdrop the communications. Motivated by this, we investigate privacy properties of the algorithm and identify to what extent privacy is preserved when all communicated variables are compromised. Finally, we demonstrate practical applications of our theoretical findings on two case studies; namely, on an energy consumption game and a coordinated charging of electric vehicles.

AbstractMetal organic frameworks (MOFs), which constitute a new class of porous organic–inorganic hybrid materials, have gained considerable attention in the fields of electrochemical energy storage and conversion devices owing to their open topological structures, large surface areas, tunable morphologies, and extreme redox activity. A synthesis protocol that comprises coprecipitation followed by controlled calcination processes to design a battery‐type electrode is used. This electrode consists of three‐dimensional (3D), ant cave‐like polyhedrons of nickel–cobalt alloy on graphitic carbon (GC; NiCo@GC) nanostructures; trimesic acid is used as a potential MOF‐linker. The developed NiCo@GC sample exhibits mesoporous characteristics with the maximum surface area of 94.08 m2 g−1 at 77 K. In addition, the redox activity at different sweep rates reveals the battery‐type charge storage behavior of the NiCo@GC electrode; its three‐electrode assembly provides 444 C g−1 specific capacity at 2 A g−1 with long‐term capacity retention. The constructed supercapattery (SC) devices (i.e., AC//NiCo@GC) achieved capacity, specific energy, and specific power are 74.3 mAh g−1, 39.5 Wh kg−1, and 665 W kg−1, respectively. Owing to its reasonable electrochemical characteristics, the prepared NiCo@GC material is a promising candidate for supercapattery electrodes for portable electronic devices.

Authors: Hayasaka Noboru , Nakajima Yuya , Futagami Takuya 
Published: February 2022

AbstractIn this paper, we aim to clarify the effectiveness of a thermal‐based sensor, which applies image recognition technique to thermal image to measure occupancy state. Our experiment, which was conducted at a single private office over 8 days, evaluated both energy‐saving rate of occupancy control and F‐measure, which is the comprehensive metric of measurement accuracy. The thermal‐based sensor increased the F‐measure and energy‐saving rate by 2.23% and 27.91%, respectively, compared with the passive infrared sensor, which measures the occupancy state on the basis of change in infrared temperature. Compared with an image‐based sensor, which applies image recognition technique to visible image, it can provide high privacy and security preserving capability and detect occupants under completely dark environment. However, the F‐measure and energy‐saving rate were decreased by 3.13% and 19.07%, respectively. Further results and discussion are included herein toward analysis and improvement of the thermal‐based sensor. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
Nimbolide retards T cell lymphoma progression by altering apoptosis, glucose metabolism, pH regulation, and ROS homeostasis
Authors: Jaiswara Pradip Kumar , Kumar Ajay 
Published: February 2022

AbstractNimbolide is reported as one of the potential anticancer candidates of the neem tree (Azadirachta indica A. Juss). The cytotoxic action of nimbolide has been well reported against a wide number of malignancies, including breast, prostate, lung, liver, and cervix cancers. Interestingly, only a few in vivo studies conducted on B cell lymphoma, glioblastoma, pancreatic cancer, and buccal pouch carcinoma have shown the in vivo antitumor efficacy of nimbolide. Therefore, it is highly needed to examine the in vivo antineoplastic activity of nimbolide on a wide variety of cancers to establish nimbolide as a promising anticancer drug. In the present study, we investigated the tumor retarding action of nimbolide in a murine model of T cell lymphoma. We noticed significantly augmented apoptosis in nimbolide‐ administered tumor‐bearing mice, possibly due to down‐regulated expression of Bcl2 and up‐regulated expression of p53, cleaved caspase‐3, Cyt c, and ROS. The nimbolide treatment‐induced ROS production by suppressing the expression of antioxidant regulatory enzymes, namely superoxide dismutase and catalase. In addition, nimbolide administration impaired glycolysis and pH homeostasis with concomitant inhibition of crucial glycolysis and pH regulatory molecules such as GLUT3, LDHA, MCT1, and V‐ATPase, CAIX and NHE1, respectively. Taken together, the present investigation provides novel insights into molecular mechanisms of nimbolide inhibited T cell lymphoma progression and directs the utility of nimbolide as a potential anticancer therapeutic drug for the treatment of T cell lymphoma.

Published: February 2022

AbstractA 6‐year‐old, female, spayed, flat‐coated retriever cross presented with a 4‐month history of progressive left thoracic limb lameness that was unresponsive to medical treatment. Initial advanced imaging with computed tomography did not identify a cause, and the dog was discharged on rest and analgesia. The dog re‐presented three weeks later with worsening lameness, discomfort and a painful, palpable mass on the medial aspect of the left thoracic limb just proximal to the elbow. Further investigations included electrodiagnostics and ultrasonography, which identified a lesion of the median nerve. A surgical biopsy was taken and histopathology diagnosed a peripheral nerve sheath tumour. The dog underwent surgery for thoracic limb amputation and nerve resection, with complete margins achieved. The dog went on to recover well with no signs of relapse 39 months later. This report describes the findings and treatment of a peripheral nerve sheath tumour in the thoracic limb of a dog.
Small Island Developing States in a post‐pandemic world: Challenges and opportunities for climate action

Published: February 2022

AbstractSmall Island Developing States (SIDS) have been impacted by and responded to COVID‐19 in ways that give us clues about vulnerabilities under climate change, as well as pathways to resilience. Here, we reflect on some of these experiences drawing on case study examples from the Caribbean, Pacific, and Indian Ocean SIDS, exploring how SIDS have responded to COVID‐19 and considering the potential for coping mechanisms enacted for the pandemic to support long‐term resilience to climate change. Island responses to the pandemic highlight both new directions, like tourist schemes that capitalize on the rise of remote working in Barbados and Mauritius, and reliance on tried and tested coping mechanisms, like bartering in Fiji. Some of the actions undertaken to respond to the pressures of the pandemic, such as visa schemes promoting “digital nomadism” and efforts to grow domestic food production, have climate resilience and equity dimensions that must be unpacked if their potential to contribute to more sustainable island futures is to be realized. Importantly, the diversity of contexts and experiences described here illustrates that there is no single “best” pathway to climate‐resilient post‐pandemic futures for SIDS. While the emerging rhetoric of COVID‐19 recovery often speaks of “roadmaps,” we argue that the journey towards a climate‐resilient COVID‐19 recovery for SIDS is likely to involve detours, as solutions emerge through innovation and experiment, and knowledge‐sharing across the wider SIDS community.This article is categorized under:

Published: February 2022

AbstractSeveral methods for the oxidation of the β‐diketiminate AlI complexes (BDI)Al and (BDI*)Al with O2, Et3P=O or N2O are presented (BDI=HC[C(Me)N(DIPP)]2, DIPP=2,6‐diisopropylphenyl; BDI*=HC[C(tBu)N(DIPP)]2). The selectivity of alumoxane formation depends strongly on the nature of the β‐diketiminate ligand, the experimental procedure and the solvent. The mononuclear alumoxanes (BDI)Al=O and (BDI*)Al=O are highly reactive intermediates that cannot be isolated but either aggregate to give less reactive dimers or decompose by internal C−H activation of a backbone Me group or an iPr group. Ethereal solvents like Et2O react with alumoxanes to give (BDI)Al(OEt)OH and ethylene by β‐H elimination. In case of N2O oxidation, subsequent reaction with a second equivalent of N2O to form the hyponitrite complexes (BDI)Al(N2O2) and (BDI*)Al(N2O2) is observed. Details of the alumoxane formation, reactivity and decomposition have been obtained by DFT calculations. These calculations also underscore their rather bipolar character, represented by the resonance structure (BDI)Al+−O−, and estimate the σ‐ and π‐bond character of the Al=O bond at circa 76 % and 24 %, respectively.

Abstract
Purpose
The increasing number of implant-associated infections during trauma and orthopedic surgery caused by biofilm-forming Staphylococcus aureus in combination with an increasing resistance of conventional antibiotics requires new therapeutic strategies. One possibility could be testing for different therapeutic strategies with differently coated plates. Therefore, a clinically realistic model is required. The pig offers the best comparability to the human situation, thus it was chosen for this model. The present study characterizes a novel model of a standardized low-grade acute osteitis with bone defect in the femur in mini-pigs, which is stabilized by a titanium locking plate to enable further studies with various coatings.

Methods
A bone defect was performed on the femur of 7 Aachen mini-pigs and infected with Methicillin-resistant S. aureus (MRSA ATCC 33592). The defect zone was stabilized with a titanium plate. After 14 days, a plate change, wound debridement and lavage were performed. Finally, after 42 days, the animals were lavaged and debrided again, followed by euthanasia. The fracture healing was evaluated radiologically and histologically.

Results
A local osteitis with radiologically visible lysis of the bone could be established. The unchanged high Colony-forming Units (CFU) in lavage, the significant differences in Interleukin (IL)-6 in blood compared to lavage and the lack of increase in Alkaline Phosphates (ALP) in serum over the entire observation period show the constant local infection.

Conclusion
The study shows the successful induction of local osteitis with lysis of the bone and the lack of enzymatic activity to mineralize the bone. Therefore, this standardized mini-pig model can be used in further clinical studies, to investigate various coated implants, bone healing, biofilm formation and immune response in implant-associated osteitis.
Kinetic modeling of a Sangiovese wine’s chemical and physical parameters during one-year aging in different tank materials

AbstractThe present study aimed to model the kinetics of factors involved in wine aging to highlight the effects caused by different tank materials. It is known that materials affect wine composition through releasing of tannins, elementals and allowing different level of oxygen permeation. To monitor how the composition of a red wine was influenced by the contact with different kind of material, a Sangiovese red wine from the 2018 harvest was aged for one-year simultaneously in six different 5 hL tank materials including stainless steel, epoxy-coated concrete, uncoated concrete, raw earthenware, new and used oak wood. The registered differences were described through kinetic modeling of some wine’s chemical and physical parameters. In particular, the one-year evolution of the dissolved oxygen, redox potential and phenolic composition of the wines showed significant differences according to the tank material. Like the oak barrels, the raw earthenware amphorae and uncoated concrete tanks enhanced the polymerisation of the phenolic fraction of the wine. Instead, the stainless steel and epoxy-coated concrete proved to be the most chemically inert materials as they showed the least variability of redox potential and the lowest degree of color evolution.

AbstractBackgroundThe foley catheter balloon tamponade (FCBT) has been widely employed in the management of trauma. This study reviews our cumulative experience with the use of FCBT in the management of patients presenting with a penetrating neck injury (PNI).MethodsA retrospective study was conducted at a major trauma centre in South Africa over a 9‐year period from January 2012 to December 2020. All patients who presented with a PNI who had FCBT were included.ResultsA total of 1581 patients with a PNI were managed by our trauma centre, and 44 (3%) patients had an FCBT. Of the 44 cases of FCBT, stab wounds accounted for 93% (41/44) and the remaining 7% were for gunshot wounds. Seventy‐five per cent of all FCBT (33/44) were inserted at a rural hospital prior to transfer to our trauma centre; the remaining 25% (11/44) were inserted in our resuscitation room. The success rate of FCBT was 80% (35/44), allowing further CT with angiography (CTA) to be performed. CTA findings were: 10/35 (29%) positive, 18/35 (51%) negative, and 7/35 (20%) equivocal. Fifteen patients required additional intervention (open surgery or endovascular intervention). The overall morbidity was 14% (6/44). Eighteen per cent required intensive care unit admission. The median length of stay was 1 day. The overall mortality rate was 11% (5/44).ConclusionFCBT is a simple and effective technique as an adjunct in the management of major haemorrhage from a PNI. In highly selective patients, it may also be used as definitive management.
