Authors: Emmanouilidis Sara , Hackney Madeleine E. , Slade Susan C , Heng Hazel , Jazayeri Dana , Morris Meg E.
Published: October 2021

Objective. To evaluate the outcomes of face-to-face, digital, and virtual modes of dancing for people living with Parkinson’s disease (PD). Design. Systematic review informed by Cochrane and PRIMSA guidelines. Data Sources. Seven electronic databases were searched: AMED, Cochrane, PEDro, CINHAL, PsycINFO, EMBASE, and MEDLINE. Methods. Eligible studies were randomised controlled trials (RCT) and other trials with quantitative data. The PEDro scale evaluated risk of bias for RCTs. Joanna Briggs Institute instruments were used to critically appraise non-RCTs. The primary outcome was the feasibility of dance interventions, and the secondary outcomes included gait, balance, quality of life, and disability. Results. The search yielded 8,327 articles after duplicates were removed and 38 met the inclusion criteria. Seven were at high risk of bias, 20 had moderate risk of bias, and 11 had low risk of bias. There was moderately strong evidence that dance therapy was beneficial for balance, gait, quality of life, and disability. There was good adherence to digital delivery of dance interventions and, for people with PD, online dance was easy to access. Conclusion. Dancing is an accessible form of exercise that can benefit mobility and quality of life in people with PD. The COVID-19 pandemic and this review have drawn attention to the benefits of access to digital modes of physical activity for people living with chronic neurological conditions.

Authors: Shu Jianfeng , Li Dong , Tao Weijing , Chen Shu
Published: October 2021

In this prospective study, we used the random number table method to equally divide 141 patients with chronic nonspecific low back pain (CNLBP) who met the inclusion criteria into 3 groups. One group who received massage manipulation therapy was recorded as the manipulation group (n = 47), one other group who received core strength training therapy was recorded as the training group (n = 47), and the other group who received massage manipulation combined with core strength training was recorded as the combination group (n = 47). All the patients were treated for 1w as the course of treatment, with the treatment conducted for 5 d/w for 4 w and 12 w of follow-up. The efficacies of the 3 groups were evaluated after treatment, and the visual analog scale (VAS) scores, Oswestry disability index (ODI) scores, and waist dynamic and static muscle endurance before and after treatment of the 3 groups were compared, and the long-term efficacies of the 3 groups were evaluated combined with the VAS scores at 6 w and 12 w after treatment. Our result was that, after treatment, the total effective rate of the combination group (95.74%) is significantly better than that of the manipulation group (80.85%) and the training group (78.72%) (

P
<
0.05

). After treatment, the VAS and ODI scores of the 3 groups significantly decreased, and the waist dynamic endurance and static muscle endurance significantly increased, and the condition of the combination group was significantly improved compared with that of the manipulation group and the training group (

P
<
0.05

). At 6w and 12w after treatment, the VAS scores of the manipulation group and training group were increased compared with those at the end of treatment (

P
<
0.05

), there was no significant change in the combination group (

P
<
0.05

), and the VAS scores of the combination group at 6 w and 12 w after treatment were lower than those of the manipulation group and training group at the same time point (

P
<
0.05

). This suggests that the synergistic effect of massage manipulation combined with core strength training in the treatment of CNLBP can effectively alleviate patients’ pain and waist dysfunction, enhance dynamic and static muscle endurance, and have significant short-term and long-term effects, which are worthy of promotion.

Eccentricity-Based Topological Invariants of Dominating David-Derived Networks
Authors: Imran Muhammad , Zobair Mian Muhammad , Shaker Hani
Published: October 2021

A topological index is a numerical descriptor of the molecular structure based on certain topological features of the corresponding molecular graph. Topological indices are scientific contemplations of a graph that outline its subatomic topology and are graph-invariant. In a QSAR/QSPR study, topological indices are utilized to anticipate the physico-concoction resources and bioactivity of compounds. In this paper, we study some distance-based topological indices such as eccentric connectivity index (ECI), total eccentricity index (TEI), and eccentricity-based Zagreb index for dominating David-derived networks (DD network) and provide exact formulae of the said indices. These outcomes are valuable to organize the science of hidden topologies of this network.

Published: October 2021

Background. This study was conducted to evaluate the anti‐SARS‐CoV‐2 IgM and IgG antibodies among healthcare workers in Guilan. Methods. This cross-sectional study was conducted on 503 healthcare workers. Between April and May 2020, blood samples were collected from the healthcare workers of Razi Hospital in Rasht, Guilan, Iran. Enzyme-linked immunosorbent assay (ELISA) was used for the detection and quantitation of anti‐SARS‐CoV‐2 IgM/IgG antibodies by using kits made by Pishtaz Teb Company, Tehran, Iran. Results. From a total of 503 participants, the result of the anti‐SARS‐CoV‐2 IgM antibody test was positive in 28 subjects (5.6%) and the anti‐SARS‐CoV‐2 IgG antibody test was positive in171 subjects (34%). Participants in the age group of 35–54 years were significantly more likely to have a positive anti‐SARS‐CoV‐2 antibody test than the age group of 20–34 years (odds ratio = 1.53, 95% CI: 1.04–2.25,

P
=
0.029

). Also, physicians were significantly more likely to have a positive antibody test than office workers (odds ratio = 1.92, 95% CI: 1.04–3.54,

P
=
0.037

). The wide range of symptoms was significantly associated with the positive anti‐SARS‐CoV‐2 antibody test. The most significant association was observed between fever and a positive anti‐SARS‐CoV‐2 antibody test (odds ratio = 3.03, 95% CI: 2.06–4.44,

P
<
0.001

). Conclusion. The results of the current study indicated that the seroprevalence of COVID-19 was high among healthcare workers of Guilan Province. It seems that this finding was due to the earlier exposure to COVID-19 and the lack of awareness and preparedness to deal with the pandemic in Iran, compared to other countries.

Published: October 2021

Here, we discuss the safety and management of adverse events associated with pembrolizumab plus axitinib combination therapy for metastatic renal cell carcinoma in patients on hemodialysis. A 76-year-old man was diagnosed with cT3aN0M0 renal cell carcinoma due to gross hematuria. Stereoscopic radiotherapy for metastatic lesions of the ipsilateral kidney was performed 9 years after right laparoscopic radical nephrectomy. Soon after, the patient started to receive hemodialysis due to end-stage renal disease. Further stereoscopic radiotherapy was needed for metastasis of the ipsilateral kidney and lung. Fifteen years after diagnosis, systemic therapy was necessary to control new metastases, such as in the right scapular bone. We selected pembrolizumab plus axitinib combination therapy as the first-line systemic therapy for any risk as defined by the International Metastatic RCC Database Consortium. Although we needed to pay attention to the adverse events unique to hemodialysis, he underwent this combination therapy without any difficulty for 6 months. Here, we report the practice of combination therapy in patients on hemodialysis in light of the literature.

Published: October 2021

Background:

Progression of nontarget lesions (NTLs) after percutaneous coronary intervention (PCI) has been reported. However, it remains unknown whether progression of NTLs was causally related to stenting. This study was undertaken to test the hypothesis that stent implantation triggers acute phase response and systemic inflammation which may be associated with progression of NTLs.

Methods:

Thirty New Zealand rabbits receiving endothelial denudation and atherogenic diet were randomly divided into stenting, sham, and control groups. Angiography and intravascular ultrasonography were performed in the stenting and sham groups, and stent implantation performed only in the stenting group. Histopathologic study was conducted and serum levels of APPs (acute phase proteins) measured in all rabbits. Proteomics analysis was performed to screen the potential proteins related to NTLs progression after stent implantation. The serum levels of APPs and inflammatory cytokines were measured in 147 patients undergoing coronary angiography or PCI.

Results:

Plaque burden in the NTLs was significantly increased 12 weeks after stent implantation in the stenting group versus sham group. Serum levels of APPs and their protein expression in NTLs were significantly increased and responsible for stenting-triggered inflammation. In patients receiving PCI, serum levels of SAA-1 (serum amyloid A protein 1), CRP (C-reactive protein), TNF (tumor necrosis factor)-α, and IL (interleukin)-6 were substantially elevated up to 1 month post-PCI.

Conclusions:

In a rabbit model of atherosclerosis, stent implantation triggered acute phase response and systemic inflammation, which was associated with increased plaque burden and pathological features of unstable plaque in NTLs. The potential mechanism involved vessel injury-triggered acute phase response manifested as increased serum levels of SAA-1, CRP, and LBP (lipopolysaccharide-binding protein) and their protein expression in NTLs. These findings provided a new insight into the relation between stent implantation and progression of NTLs, and further studies are warranted to clarify the detailed mechanism and clinical significance of these preliminary results.

Authors: Li Shanshan , Zhang Feng , Tao Yuan , Du Xing , Sun Zhonghua
Published: October 2021

ABSTRACTMethazolamide (MET) was used as a model drug. Chitosan (Chi), which had the advantages of biodegradation, non-toxicity and biocompatibility, was used to modify the surface of solid lipid nanoparticles (SLNs) to construct a stable and targeted drug carrier for eyes. Chi modified MET SLNs were prepared by emulsion evaporation low-temperature curing method. Then, the samples were characterized by infrared spectroscopy and X-ray diffraction. Its effect on hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in retinal pigment epithelial (RPE) cells was analyzed. Meanwhile, the effect of the prepared nanoparticles (NPs) on the migration of retinal microvascular endothelial cells was analyzed. The results showed that the optimal formulation of Chi modified MET SLNs was as follows: 35 mg MET, 80 mg glyceryl monostearate (GMS), 15 mg phospholipid, and 10 ml anhydrous ethanol, which were heated and dissolved at 80 °C to form an organic phase. Besides, 20 ml solution composed of 1% Tween80 and 2% Polyethylene glycogen (PEG) 400 was used as the internal aqueous phase. Under hypoxia condition, the up-regulation of HIF-1αand VEGF expression was significantly inhibited; the RPE cells treated with prepared NPs migrated to the center, so as to inhibit the migration of vascular endothelial cells. The average inhibition rate was 44%.

Published: October 2021

ABSTRACTThe effect of double-layer nanoparticles (DNPs) on vascular restenosis was investigated in this study, which were prepared by combining vascular endothelial growth factor (VEGF) and paclitaxel (PTX). Different blank NPs (Blank), VEGF NPs, PTX-NPs single-layer NPs
(PTX-NPs), and DNPs were prepared with VEGF, PTX, polylactic-polyglycolic acid (PLGA), and polyvinyl alcohol (PVA), so as to analyze the cytotoxicity of NPs. Besides, different NPs were compared in terms of the characterization, encapsulation efficiency (EE), in vitro release (IVR),
and cell proliferation inhibition ability. 30 adult New Zealand white rabbits were selected to construct a balloon injury model (BIM). Then, they were divided into 5 groups according to different treatment NPs, including a model group (BIM), a Blank group (BIM + Blank NPs); a PTX-NP group
(BIM + PTX-NPs), a VEGF-NPs group (BIM + VEGF-NPs), and DNPs group (BIM + DNPs), with 6 rabbits in each group. There was a comparison on the histology, arterial stenosis, hyperplasia index (HI), and intimal thickness (IT) of arterial vessels from different groups, and immunohistochemistry
was employed to analyze the changes of VEGF and C-reactive protein (CRP) protein expression levels in arterial tissues of different groups. The results showed that the cell survival rate (SR) was 88.69 ±3.17% and 90.64 ± 1.86% in turn when PLGA and PVA were both 100 ¿tg/mL.
The polydispersity index (PDI), minimal Zeta potential (ZP), and average particle size (APS) of DNPs were 0.16 ±0.02, -8.45 ±0.07, and 242.26 ±2.58 nm, respectively. The drug loading (DL) of PTX and plasmid VEGF 165 in DNPs were 29.33% and 4.93%, respectively. The release
of PTX from DNPs on the 30th day was close to 50%, and the cumulative release of deoxyribonucleic acid (DNA) was close to 75%. There was no obvious difference in the cell SR within 7 days after DNPs were added into Chinese Hamster ovary (CHO) cells and vascular smooth muscle cells (VSMC) compared
with the control group (P > 0.05). The arterial stenosis, HI, and IT of the DNPs group were greatly lower than those of the model group (P < 0.05). The expression of VEGF protein in arterial tissues of DNPs group was higher in contrast to the model group (P <
0.01), while the expression of CRP protein was lower than that of the model group (P < 0.05). It showed that the DNPs combined with VEGF and paclitaxel administered by balloon infusion could obviously inhibit the vascular restenosis by increasing the expression of VEGF and reducing
the expression of CRP, which provided a reference for the clinical prevention and treatment of postoperative vascular restenosis.
Preparation of Gd-Au Dendrimer-Entrapped Gold Nanoparticles-Folic Acid Nanoparticles and Its Application in Computed Tomography/Magnetic Resonance Imaging Dual-Modality Diagnosis of Abdominal Tumors
Authors: Zhang Yumei , Pei Ruina , Luo Tao
Published: October 2021

ABSTRACTThe development of nanomaterials, especially the development of multi-modality imaging nanoprobe technology has become a reality for tumor imaging diagnosis. In this study, the gadolinium ion chelating agent (2,2′,2′′-(10-(2-(2, 5-dioxopyrrolidin-1-oxyl)-2
oxoethyl)-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7-tri)triacetic acid) (DOTA-NHS) and polyethylene glycol (PEG)-modified targeting ligand PEG-folic acid (FA) were grafted onto the PEG-modified fifth-generation polyamide-amine dendrimer (P5-NH2), which were undertaken as standards
to wrap gold nanoparticles. Then, remaining amino group was acetylated to acquire Gd–Au DENPS-FA nanoparticles. Biocompatibility and cytotoxicity of nanoparticles were analyzed while characterizing them. The cases with unidentified tumors (mass diameter >4.5 cm) of abdominal or pelvic
origin were selected and used for clinical study of computed tomography (CT)/magnetic resonance imaging (MRI) dual-modality abdominal tumors. In the test, average particle size of Gd-Au DENPs-FA nanoparticles was 4.2 nm, and they had good water solubility and stability in aqueous solution.
When concentration of Au+ nanoparticles increased, the cell morphology remained normal, only a small number of round cells appeared, and the cell activity remained above 80%. GD-Au DENPs-FA nanoparticles had a good targeting specificity for KB cells with high folate receptor expression.
During 6–24 hours of injection, the signal at the tumor site of the patient was enhanced markedly, namely the targeted gold nanoparticles were bound to the tumor tissue and the metabolic rate was slow. Based on this material, CT/MRI imaging could be performed in the patient’s body
and further used for the early diagnosis of abdominal tumors.

Published: October 2021

ABSTRACTIn this work, polylactic acid/polycaprolactone/silk fibroin (PLA/PCL/SF) nanofiber scaffolds with different mass ratios were prepared by electrospinning technology. The morphology and structure of the nanofiber scaffold were characterized with the scanning electron
microscope (SEM), and its porosity and adsorption were tested using the Fourier transform infrared spectrometer (FTIR). 24 New Zealand white rabbits were rolled into control group (n = 8, with autologous tendons) and experimental group (n = 16) randomly. The PLA/PCL/SF nanofiber
scaffolds were adopted to wrap autologous tendons to establish extra-articular models. Tendon-bone healing was evaluated six weeks after surgery through histological and biomechanical tests, and the related gene expressions in tissue cells were detected. It turned out that mass ratio of PLA/PCL
and SF components had a considerable impact on the morphology of the nanofiber scaffold. The surface of nanofiber with a mass ratio of 3:1 was distributed with dense pores. As the content of SF increased, the porosity and adsorption of the nanofiber scaffold gradually decreased. Moreover,
the experimental results suggested that the addition of SF improved the hydrophilicity of PLA/PCL/SF scaffold, which was beneficial to the adhesion and proliferation of NIH/3T3 (a mouse embryonic fibroblast cell line established by the National Institutes of Health (NIH)). In addition, histological
observation results showed that the width of the tendon-bone interface (TBI) of rabbits in control group was still relatively large at the 6th week after the surgery, with poor healing effect and disordered collagen arrangement. The widths of the TBI of the material group and rehabilitation
group were substantially narrower relative to that in control group, and the collagen was arranged regularly. It was suggested that the healing effects between tendon and bone in material group and rehabilitation group were accelerated, and the effect in the rehabilitation group was superior
to that of material group, indicating that rehabilitation exercise could organize the negative effects of training in postoperative rehabilitation training and promote the healing between tendons and bones.
Anthropometric Changes in Spaceflight
Authors: Young Karen S. , Kim K. Han , Rajulu Sudhakar
Published: October 2021

Objective

This study aims to identify the change in anthropometric measurements during spaceflight due to microgravity exposure.

Background

Comprehensive and accurate anthropometric measurements are crucial to assess body shape and size changes in microgravity. However, only limited anthropometric data have been available from the astronauts in spaceflight.

Methods

A new photogrammetry-based technique in combination with a tape-measure method was used for anthropometric measurements from nine crewmembers on the International Space Station. Measurements included circumference and height for body segments (chest, waist, bicep, thigh, calf). The time-dependent variations were also assessed across pre-, in-, and postflight conditions.

Results

Stature showed a biphasic change with up to 3% increase at the early flight phase, followed by a steady phase during the remaining flight. Postflight measurements returned to a similar level of the preflight. Other linear measurements, including acromion height, showed similar trends. The chest, hip, thigh, and calf circumferences show overall decrease during the flight up to 11%, then returned close to the preflight measurement at postflight.

Conclusion

The measurements from this study provide critical information for the spacesuit and hardware design. The ground-based assessments for spacesuit fit needs to be revalidated and adjusted for in-flight extravehicular activities from this data.

Application

These data can be useful for space suit design as well as habitat, vehicle, and additional microgravity activities such as exercise, where the body shape changes can affect fit, performance, and human factors of the overall design.
COVID-19 Pandemic and Lockdown: Associations With Personality and Stress Components
Authors: Smrdu Maja , Kuder Ana , Turk Eva , Čelik Tatjana , Šet Janko , Kralj-Fišer Simona
Published: October 2021

The present study examines the role of personality traits, interpersonal relationships, and sociodemographic factors on perceived stress, related to COVID-19, and compliance with measures to mitigate its spread. Data were collected in the midst of the ‘first wave’ lockdown, with the survey completed in full by 963 participants. We measured stress, directly related to the pandemic, rather than general stress, and were able to distinguish between symptoms of emotional, behavioural, cognitive, physical stress, and alienation with high concordance. We included personality scoring with standardized T-scores, allowing for cross-study comparison, and a broader questionnaire on the participants’ support for COVID-19 mitigation measures. Results of the multiple regression models indicated that low emotional stability and introversion, and high conscientiousness, common conflicts with loved ones, and some demographics (female gender, middle age, chronic health problems) correspond to elevated stress. Conscientiousness was positively associated with total stress and some of its components, whereas opposite results were found for emotional stability. Extraversion was negatively correlated to total stress, its emotional and physical components, and alienation. Surprisingly, increased stress was not related to greater measure adherence. The present results shed light on how personality, interpersonal relationships, and sociodemographic factors influence people’s stress response during a pandemic.

Published: October 2021

To achieve efficient and environmental reuse of waste ribbons, artworks reconstructed from waste ribbons for decorative occasions were inspired by the dedicated and determined people working against coronavirus disease 2019 (COVID-19) and developed through a handmade and delicate strategy. With the theme of ‘Ordinary * Extraordinary,’ the artworks aim to convey endless positive energy and hope to people suffering from COVID-19. To fulfill the art reconstruction, the design idea, composition design and color design were comprehensively considered and carefully described. The artworks were applied for decoration in hospital wards and the home environment. Their composition and color gave medical workers, patients and ordinary people suffering from COVID-19 a sense of comfort and warmth. All positive energy from our artworks accompanied people and encouraged them never to give up and overcome COVID-19. The art reconstruction of waste ribbons proposed in this study may provide an excellent way for the reuse of waste ribbons. More importantly, it improves the added value of products and strengthens people's determination to overcome COVID-19.

Authors: Asfand Norina , Daukantienė Virginija
Published: October 2021

Different fiber blends, knit patterns, and treatments may be applied to increase the functionality and comfort of knitted fabrics. In this research, the physical properties and bending stiffness of 1 × 1 rib and half-milano rib fabrics with four fiber blends (90% cotton/10% antistatic PET, 80% cotton/20% antistatic PET, 70% cotton/30% antistatic PET, and 65% cotton/35% antistatic PET) applied to each knit pattern were studied. The effect of fabric direction (course and wale), technical side (face side and back side), and treatment (dying, softening with Aquasoft® SI hydrophilic softener, and Polygiene VO-600 antibacterial finish) on the physical characteristics and bending stiffness of the fabrics was evaluated. The results revealed that dyeing and softening increased the fabric area density and both wale and course densities and decreased fabric thicknesses compared to the control fabrics. The antibacterial finish applied to the softened samples did not change the physical properties. Bending stiffness in the course direction was lower than in the wale direction, and it was higher for technical face samples than for technical back ones. The 1 × 1 rib knitted fabrics showed lower stiffness than the half-milano rib fabrics. Treatment of the investigated fabrics decreased bending stiffness for both treatment sample groups compared to the control group.
Interview ready: A student-led artistic project as an authentic experience to support pre-service music teachers’ pathways to employment
Authors: Jenkins Louise , Crawford Renée
Published: October 2021

Facilitating the development of employable graduates is an important part of initial teacher education (ITE) courses globally. School administrators seek to employ high quality teachers who will contribute positively to student learning and the school community. The perception of a candidate’s level of employability in a job interview though, will influence the outcome of their application significantly. ITE graduates should therefore endeavour to be interview ready as this is a crucial step towards being employed. We investigated the impact that a student-led artistic project had on the development of Australian ITE music teachers’ interview readiness and employability. Data were collected via three focus groups and one semi-structured individual interview. The data indicated that the artistic project experience contributed positively to the development of relevant skills and understandings which supported participants’ interview readiness and employability. Two major themes emerged- the authenticity of the artistic project and the transferability of the skills and understandings learned into an imagined or current school context, including the job interview process. The findings suggest that ITE music courses should include more authentic experiences to develop their students’ professional ‘soft’ skills and interview readiness. This will support their preparation for the employment process and their professional duties.

Authors: Hovsepyan Shushan , Hakobyan Lusine , Mkhitaryan Armen , Terenziani Monica , Ferrari Andrea , Sironi Giovanna , Schneider Dominik T. , Tamamyan Gevorg
Published: October 2021

Background:

The lack of internationally recognized guidelines for very rare tumors, such as juvenile granulosa cell tumors (JGCTs), which are nonepithelial, unusual ovarian tumors, is a challenge for pediatric oncologists, especially in developing countries with limited resources and experience in treating rare tumors.

Methods:

We report clinical data of 2 girls with JGCTs treated at the Pediatric Cancer and Blood Disorders Center of Armenia with the assistance of the EXPeRT (European Cooperative Study Group for Pediatric Rare Tumors) international cooperation panel.

Case presentation:

Two girls (16 and 15 years old) with JGCTs of the ovaries, stage Ic, underwent surgery and, with consultation through an online advisory board ( http://vrt.cineca.it/ ), received 4 cycles of chemotherapy according to the PEI regimen (cisplatin, etoposide, ifosfamide).

Conclusion:

Very rare tumors, especially in advanced stages, have limited data and a low survival rate. International collaboration with the EXPeRT group is beneficial for physicians with limited experience and facilitates research in pediatric oncology.
Contribution of Risk Perception and Communication in Aviation Safety Events
Authors: Chionis Dimitrios , Karanikas Nektarios , Iordan Alice-Rebecca , Svensson-Dianellou Antonia
Published: October 2021

Although effective risk management during operations relies on risk perception and risk communication, the aviation industry has not systematically considered the contribution of these two constructs to safety events. This study analyzed a representative sample of safety investigation reports (1) to identify the degree to which risk perception and communication and their factors have been influential overall and across various flight operation stages of investigated events, and (2) to examine whether their contribution has changed with time. The analysis of 140 reports showed environmental factors affected risk communication and perception most frequently, whereas emotional and physiological factors were found in the sample with very low frequencies. Also, risk communication and perception and their factors did not appear with the same frequency across the various flight stages, and a few variations were observed over time. The aviation industry could consider the results of this study to steer its efforts toward mitigating the adverse effects of factors related to ineffective risk perception and communication. This could include the inclusion of respective factors in safety reporting schemes, investigation methods and analyses and, possibly, a tailored approach to the various flight stages and targeted risk literacy interventions.
Relative Mobility Analysis of a Public Transport Network in Comparison with Car Travel
Authors: Kutadinata Ronny , Dey Subhrasankha , Leow Dickson
Published: October 2021

This work is motivated by the high rate of private car use by commuters in Australian cities. Considering the various benefits of public transport (PT), it is imperative to analyze the shortcomings of the PT networks in comparison to car travel. For this purpose, this work focuses on analyzing the travel time difference between PT and car journeys. This paper presents a methodology to analyze the relative mobility of a PT network in comparison to car travel. The key component of this methodology is the use of two complementary relative mobility metrics that are developed to determine the portions of PT journeys that are inefficient (time-wise) in comparison to car trips. The first metric is the point-to-point relative mobility used to perform spatial distribution analysis, and the second is the PT line relative mobility that evaluates the performance of the PT routes. A demonstration of the methodology is presented by using a case study from Melbourne (Australia). The results of the case study show some inefficient segments of the PT services in several areas, and within the Port Melbourne area in particular. Therefore, this information can be used to assist decision makers to prioritize PT improvements to encourage mode shifts to PT.

Coronavirus disease-2019 (COVID-19)-associated pulmonary aspergillosis (CAPA) is a new disease characterized by secondary Aspergillus mold infection in patients with COVID-19. It primarily affects patients with COVID-19 in critical state with acute respiratory distress syndrome, requiring intensive care and mechanical ventilation. CAPA has a higher mortality rate than COVID-19, posing a serious threat to affected individuals. COVID-19 is a potential risk factor for CAPA and has already claimed a massive death toll worldwide since its outbreak in December 2019. Its second wave is currently progressing towards a peak, while the third wave of this devastating pandemic is expected to follow. Therefore, an early and accurate diagnosis of CAPA is of utmost importance for effective clinical management of this highly fatal disease. However, there are no uniform criteria for diagnosing CAPA in an intensive care setting. Therefore, based on a review of existing information and our own experience, we have proposed new criteria in the form of practice guidelines for diagnosing CAPA, focusing on the points relevant for intensivists and pulmonary and critical care physicians. The main highlights of these guidelines include the role of CAPA-appropriate test specimens, clinical risk factors, computed tomography of the thorax, and non-culture-based indirect and direct mycological evidence for diagnosing CAPA in the intensive care unit. These guidelines classify the diagnosis of CAPA into suspected, possible, and probable categories to facilitate clinical decision-making. We hope that these practice guidelines will adequately address the diagnostic challenges of CAPA, providing an easy-to-use and practical algorithm to clinicians for rapid diagnosis and clinical management of the disease.
How to manage feelings and emotions in a pandemic? the importance of affective containment
Authors: Fraser Rachael , Hordern Jim
Published: October 2021

In this short reflective piece, we first outline how feelings and emotions (or ‘affections’) are understood in psychodynamic approaches, and briefly discuss how these may be controlled or ‘contained’ in organisational contexts. We then reflect on the recent experiences of one of us (Rachael) as a school leader seeking to contain feelings and emotions during the COVID-19 pandemic.
Theorizing the form and impact of sport scandals
Authors: Wagner Ulrik , Storm Rasmus K.
Published: October 2021

Sport scandals have attracted significant interest within and beyond the sociology of sport. However, developing a theoretical understanding of sport scandals has so far been neglected. Therefore, the two-fold purpose of this conceptual paper is to outline a theoretical model for understanding the form of a sport scandal, and to construct two typical sport scandals that can assist us in theorizing and differentiating how sport scandals may have varying effects on society. In our work, we rely on insights on form formulated by the German sociologist Niklas Luhmann combined with notions of ideal types derived from Max Weber. Accordingly, scandals are described as examples of paradoxical forms where excluded meaning re-enters to create spaces of temporary liminality. Despite their common characteristics, we are able to construct two ideal types of scandals – bureaucratic fallacy and charismatic failure – to understand why scandals may have varying impacts on the environment.
Experiential Wilderness-Based Professional Development: Beliefs and Confidence of Participant Educators

Published: October 2021

Background: Continuing education programs for teachers seek to enhance outcomes for participants and their students. Experiential wilderness-based programs offer outdoor-recreational activities and experiential teaching initiatives. Research needs to be conducted to reveal how they influence individual behaviors. Purpose: This research investigated whether a wilderness-based program influenced individual beliefs and confidence in using experiential teaching methods within a classroom. Methodology/Approach: A pre-, post-, and follow-up closed survey was administered to educators who had participated in the North Carolina Outward Bound Educators Initiative (NCOBEI) 2017–2018. Furthermore, retrospective follow-up surveys were administered to alumni (years 2007–2016). Responses were analyzed to determine how participants integrated learning within the classroom. Findings/Conclusions: Participation positively influenced educators’ beliefs, confidence, and intentions to implement experiential techniques within the classroom immediately following the experience, although the benefits diminished over time. Educator beliefs and confidence were poor predictors of using experiential learning in the classroom. Implications: Experiential wilderness-based professional development (PD) has the potential to positively build confidence and skills for use in the classroom. PD and future research should address how to perpetuate the influence of wilderness-based continuing PD programs at the individual and institutional levels.

Published: October 2021

Background:

The orthopaedic conditions and systemic comorbidities that occur in patients who require bone block tibiotalocalcaneal (TTC) arthrodesis have made this procedure associated with a higher-than-normal risk of nonunion, graft collapse, hardware failure, and amputation. Here, we present a novel approach to bone block TTC arthrodesis using adjunctive osteoinductive agents and a prolonged course of protected weightbearing to assess if we could improve on historical outcomes. We also evaluated the efficacy of a vascularized medial femoral condyle (MFC) free flap to augment TTC arthrodesis.

Methods:

Fourteen adult patients underwent bone block TTC arthrodesis biologically augmented with fresh-frozen femoral head allograft, bone marrow aspirate concentrate, and demineralized bone matrix cortical fibers. Three patients with soft tissue defects underwent vascularized reconstruction with an MFC free flap. Radiographic union, the Foot Function Index (FFI), and PROMIS pain interference (PI), and physical function (PF) scores were assessed at follow-up.

Results:

TTC fusion was documented on plain radiograph in 13 of 14 patients (92.9%) and CT in 10 of 11 patients (90.9%). Mean time to fusion was 183.2 ± 83.2 days. One patient (7.1%) experienced nonunion and persistent infection requiring amputation. Patients who underwent vascularized bone grafting had significantly shorter time to fusion (112.3 ± 31.7 days vs 204.4 ± 82.7 days, P = .05). Patient-reported outcomes revealed mild to moderate pain and dysfunction after 1 year (mean FFI = 41.0% ± 23.1%, PROMIS PI = 58.3 ± 1.8, PROMIS PF = 39.0 ± 2.2).

Conclusion:

In this relatively small series, the biologic augmentation of bone block TTC arthrodesis with osteoinductive agents and protective weightbearing resulted in excellent rates of fusion, modest pain, and preserved function of the lower extremity in almost all those treated. Osseous healing appears to be enhanced and accelerated with application of an MFC flap. We believe that this approach offers a viable salvage option for these challenging clinical problems.

Level of Evidence:

Level IV, case series.
How Can We Increase Neighbors' Intention to Report Intimate Partner Violence Against Women During the Pandemic?
Authors: Nardi-Rodríguez Ainara , Paredes-López Nerea
Published: October 2021

During the pandemic, neighbors can be potential allies to prevent intimate partner violence against women (IPVAW). Based on the reasoned action approach, we identified the predictors and the most relevant beliefs behind neighbors' intention to report to authorities that a woman is being victimized by IPVAW. A total of 352 Spanish participants completed a questionnaire. The regression analysis showed that perceived control and subjective norm were the best predictors of the intention (33% explained variance). Social media campaigns should target perceived inhibitors such as citizens' guilt for reporting ambiguous cases and close referents (friends and family) as prescribers of the helping behavior.
MeToo and Sexual Violence Among Women in Zambia
Authors: Muzyamba Choolwe
Published: October 2021

By using a qualitative study involving 80 participants, the aim of this study is to investigate the relevance of the MeToo movement as a tool for responding to sexual violence among women in Zambia. Our findings suggest that rather than definitively establishing the MeToo movement as an incontestable good or as useless because it ignores cultural realities as argued by its critics, our findings demonstrate the diversity of how this movement is locally viewed and also illustrates the complexity and multidimensionality of how it is characterized in Zambia. Our findings thus question the folly of a “one-size-fits-all” understanding and characterization of the MeToo movement. The study ends by providing suggestions about how to navigate this complexity.
Back to the Source: Moving Upstream in the Curricular Rivers of Coloniality
Authors: James Susan , Lorenz Helene
Published: October 2021

This article shares choices made as part of an introductory decoloniality curriculum in a non-clinical community psychology M.A./PhD program where the authors are faculty members. We focus on the basics of decoloniality and decolonial pedagogies in two first-year foundational psychology courses: one course on implications of decoloniality for studying differing psychological paradigms, ontologies, and epistemologies, particularly relational ontologies that might reframe community environments, and another course on implications of decoloniality for post-humanist and indigenous qualitative research methodologies. We present currently emerging forms of theory, content, pedagogy, dialogue, artivism, and methodology in process in our work, as well as responses from students and our own reflections.
Payments in the pandemic: orchestrating and imagining cross-boundary digital money infrastructures in China during COVID-19
Authors: McDonald Tom , Shum Holy Hoi-Ki , Wong Raymond
Published: October 2021

Recent scholarship has sought to emphasise boundaries and borders as being complex social institutions that play a vital role in mediating national and global flows. This article examines transactions occurring along the boundary between Hong Kong and Mainland China, which experienced a sudden ‘hardening’ owing to travel restrictions imposed following the outbreak of COVID-19. When individuals found themselves unable to physically cross the boundary as per usual, they instead turned to mobile media to enact everyday transactions – both financial and social – between the two regions. Calling upon the notion of ‘digital passages’, we argue that the appropriation of digital money infrastructures for managing such transactions should act as a reminder for scholars to productively engage with the various forms of boundaries and borders emerging within online spaces.
Thoughts on files
Authors: Clapton Gary
Published: October 2021

With the benefit of an anthropological attention to the importance of ‘things’ and the relations between ourselves and things (‘artefacts’), this paper gives attention to the Social Work File. Despite the rise of electronic recording, social work archives remain full of thousands of files that are increasingly accessed, especially by those who have been in care, and physical file-keeping remains a regular feature of practice. There is already a body of literature relating to the information in social work files, however this paper shifts the focus from this to the nature and role of the File itself. ‘Hidden in plain sight’ but laden with meaning and capacity, I identify the little we know already about the file. The various ways files and their authors and subjects, can interact are explored together with the file’s symbolic properties and the power held by the file’s owner, and the ability of the file to ‘other’ its subject. Whilst we understand that the practice shapes the file, how might the file shape practice?
