Thermal performance of three concentrating collectors with bifacial PV cells. Part II – parametrical study
Authors: Lança Miguel , Gomes João , Cabral Diogo , Hosouli Sahand 
Published: February 2024

One of the problems in using PV cells to extract energy from sunlight is the temperature effect on PV cells. As the solar panel is heated, the conversion efficiency of light to electrical energy is diminished. Moreover, successive temperature elevations can cause dilatations in the array of cells which may also contribute to the degradation of the receiver. Some of the operating temperature mitigation approaches may include air-flow ventilation. In this study, data obtained by experimental and numerical simulations of a collector with bifacial PV cells is compared to the expressions found in the literature for the estimation of the heat transfer coefficient. Forced ventilation was applied to the studied collector as it accounts for much better heat dissipation. A new correlation for the estimation of the heat transfer coefficient is developed for such a geometry, for inlet velocities ranging between 3 and 8 m/s. Values of heat transfer coefficient estimated in the present work have been compared with studies of other researchers.
Health, mental health, and hearing indigenous voices
Authors: Amos Andrew 
Published: February 2024

Objective To identify the issues raised by the unsuccessful Voice referendum and propose removal of barriers to reporting and prevention of family violence in remote communities as the most ambitious measure of success in hearing First Nations voices. Conclusions The Voice referendum was partly justified to improve the mental health of First Nations Australians, despite concern the process and its outcome might worsen both. Aboriginal and Torres Strait Islander leaders revealed the tensions that arise between individual and communal interests when marginalised groups fight for self-determination. While a unified First Nation Voice is likely to amplify prominent messengers, we should also be interested in hearing diverse, dissenting voices. As the most marginalised group within a marginalised community, the ability to hear the voices of women and children subject to family violence in rural/remote Australian communities may be the best measure of success in overcoming the barriers that was the motivation for the referendum.
Predicting Outcomes of a Manualized Individual Career Counseling Intervention Over a One-Year Follow-Up From Trajectories of Change in Career Decision Difficulties
Authors: Milot-Lapointe Francis , Le Corff Yann 
Published: February 2024

This study tested whether trajectories of career decision difficulties identified in Milot-Lapointe and Le Corff (2023) predict outcomes of a manualized individual career counseling intervention 12 months after the intervention. Participants were 248 individuals who received an average of 7.79 sessions at a career counseling clinic and were reassessed 12 months after the intervention. Results showed that clients who experienced an optimal (Classes 1 and 2; 66% of clients) or a positive change but suboptimal (Class 3; 21% of clients) change during career counseling had negligible career decision difficulties 12 months after the intervention and were satisfied with their career decision, career situation and with counseling. Clients in Class 4, who did not experience any change during counseling (13% of clients), had significantly higher decision difficulties, were less satisfied with their career decision, career situation, counseling, and had lower life satisfaction at the 12-month follow-up compared to clients in the other classes. Results demonstrate the long-term utility of individual career counseling in producing, on average, sustainable positive outcomes for a large proportion of clients (87%). They also offer insights into the longitudinal consequences associated to variability in career counseling as clients who did not experience any change during counseling achieved poorer outcomes on the long run.
Dr. Joseph Biederman’s Enduring Legacy: Illuminating the Path to Addressing Autistic Traits in Attention Deficit Hyperactivity Disorder With Transcranial Photobiomodulation
Authors: Ceranoglu Tolga Atilla , Hutt Vater Chloe 
Published: February 2024

Objective: To review the existing literature on transcranial photobiomodulation (tPBM) treatment effects on Autism Spectrum Disorder (ASD), in search for an effective treatment of a symptom cluster identified largely by contributions from late Dr. Biederman who asserted that they frequently present with Attention Deficit Hyperactivity Disorder (ADHD). Method: A survey of two databases, PubMed and PsycINFO, for clinical trials reporting on tPBM treatment in ASD was performed. Identified manuscripts that met eligibility criteria were then reviewed. Results: Three original manuscripts reporting findings on a heterogenous group of study methods met the eligibility criteria. Despite the heterogenous nature of study designs, findings from all three studies reported tPBM treatment to be associated with improvements in ASD symptoms. No serious or treatment limiting adverse events were reported. Conclusions: A nascent body of research suggests further clinical studies investigating efficacy of tPBM in treatment of ASD symptoms should be supported.

Authors: Yılmaz Yavuz , Uzun Cicek Ayla 
Published: February 2024

Objective: To examine the cognitive disengagement syndrome (CDS) symptoms of mothers of children with attention-deficit/hyperactivity disorder (ADHD). Method: The participants consisted of 223 mothers of children with ADHD, and data were collected using the Structured Clinical Interview for DSM-5 Disorders-Clinician Version (SCID-5-CV), the Stroop Test (ST), the Barkley Adult SCT Scale (CDS), and the Adult ADHD Self-Report Scale (ASRS). Results: The participants were divided into four groups based on psychopathology: the group without any psychiatric disorder, the group with only ADHD, the group with a psychiatric disorder other than ADHD, and the group with another psychiatric disorder along with ADHD. The group with any psychiatric disorder along with ADHD had the highest CDS scores, while the group without any psychopathology had the lowest CDS scores. Conclusion: CDS seems to be a construct associated with both ADHD and other internalizing disorders. Further studies are needed to shed more light on these relationships.

Purpose This study used optical coherence tomography scanning and 3D reconstruction of the macular region in high myopia to examine more thoroughly and carefully the differences between high myopia-related macular complications with and without dome-shape macula (DSM) and to determine whether the DSM's fine structure has an effect on them. Methods Retrospective analysis of the medical records of 345 eyes with high myopia who underwent an optical coherence tomography (OCT) examination. They were divided into the DSM group (69 eyes) and the group without DSM (276 eyes). Macular complications between the two groups were compared. The height of the DSM and the diameter of the dome base were measured. And then the association between DSM type, protrusion height and macular problems were analyzed. Results Epiretinal membrane (ERM) and extrafoveal schisis occurred more frequently in the DSM group, but the was no statistically significant difference in the frequency of foveal schisis between the two groups. The majority of eyes in the DSM categorization had a horizontal oval-shaped domain. In the DSM group, there was no evident difference in the percentage of eyes with macular complications in the groups below 150 um and above 150 um. Conclusions OCT examination-based fine macular structure analysis reveals that DSM affects various macular problems in distinct ways. DSM could increase the risk of extrafoveal schisis and ERM while decreasing the risk of foveal schisis. The height of the DSM had no obvious impact on the prevalence of macular complications.

Published: February 2024

Background: Chronic kidney disease (CKD) is characterized by irreversible damage to renal function. For patients undergoing replacement therapies like hemodialysis (HD), the pain caused by arteriovenous fistula (AVF) cannulation becomes a significant aspect of their daily lives. This study aimed to examine the impact of virtual reality (VR) distraction techniques on the pain experienced during AVF needle insertion in patients undergoing HD. Materials and methods: This randomized clinical trial (RCT) recruited a total of 60 patients undergoing HD from the 9 Dey Hospital in Torbat Heydariyeh, Iran, between March and August 2022. These patients were then divided into two groups: the intervention group and the control group. The intervention group received distraction techniques using the Shinecon 4th Gen Virtual Reality Headset, while the control group received routine care services. To assess the level of pain experienced during AVF cannulation, the Visual Analog Scale (VAS) was utilized. The collected data were analyzed using SPSS20. Various statistical tests, including the Chi-square test, Mann-Whitney U test, Multiple linear regression, and independent-samples t-test, were employed for data analysis. Additionally, Cohen’s d was used to determine the effect size of the intervention. Results: The analysis of the data revealed a statistically significant difference in the mean (SD) pain scores between the control group (7.6 ± 0.8) and the intervention group (5.1 ± 0.9) ( p < 0.002 after Bonferroni correction). Furthermore, it was observed that a majority of patients in the intervention group reported experiencing moderate pain, whereas the control group experienced more severe pain. Conclusions: The study findings demonstrated that the use of virtual reality (VR) was effective in reducing the intensity of pain experienced during AVF needle insertion in patients undergoing HD. Based on these results, it is recommended to incorporate VR as a routine practice in the HD department of the hospital. Trial registration: This study, with the code no. IRCT20180429039463N3, was registered on the Iranian Registry of Clinical Trials on 28/03/2022.

Authors: Lee Kai-Ni , Chen Chien-An , Kuo Chieh , Yang Li-Yu 
Published: February 2024

Background: Arteriovenous fistula (AVF) stenosis is associated with pre-existing arterial atherosclerosis of AVF and results in significant morbidity and hospitalization for hemodialysis patients. The ankle brachial index (ABI) is a noninvasive method of assessing atherosclerosis. This study was to examine whether ABI is a significant predictor for AVF stenosis. Methods: This was a retrospective, longitudinal cohort study. Patients with hemodialysis between 1 January 2016 and 31 December 2022 were reviewed. ABI was assessed in January 2016. AVF stenosis was diagnosed by fistulography. Results: A total of 82 patients were included. Forty-two patients experienced AVF stenosis. The univariate logistic regression analysis showed that AVF stenosis was associated with age (OR: 1.045, p = 0.033), DM status (OR: 5.529, p = 0.013), 7-year averaged cholesterol level (OR: 1.018, p = 0.034), 7-year averaged triglyceride level (OR: 1.007, p = 0.017), and ABI (OR: 0.011, p < 0.001). In multivariate logistic regression analysis, ABI was a strong predictor for AVF stenosis (OR: 0.036, p = 0.023). Then, a cut-off point of ABI with optimal sensitivity and specificity for AVF stenosis was 1.01. An analysis of time to events with adjustment for other variables showed that patients with ABI < 1.01 were significantly associated with AVF stenosis (HR: 3.859, p < 0.001). Conclusions: ABI below 1.01 was associated with AVF stenosis. This finding may be useful in tailoring surveillance programs for monitoring AVF function.

Published: February 2024

Aim: The Danish Health Survey among Marginalized People is a nationwide health survey targeting people in marginalized life situations in Denmark. The aim of this paper is to present the study design, data collection methods and respondent characteristics of the survey, which was conducted in 2007, 2012, 2017 and 2022. Methods: The survey applies an outreach data collection approach which entails reaching out to social services (public and private) asking for their help with distributing self-administered paper questionnaires among their users. Themes include self-rated health, mental health, morbidity, pain, oral health, health behaviours, gambling problems, social relations, violence, sexual harassment and assault, suicide, and source of income. Results: The overall number of respondents has decreased slightly from 2007 (1290) to 2022 (1134). In all survey waves, men were overrepresented among the respondents. In 2007, women represented only 28%, which increased to 37% in 2022. There have been remarkable changes in the age distribution among respondents between 2007 and 2022. For example, the oldest age group (55–80 years) accounted for 15% of the respondents in 2007 and 40% in 2022. Conclusions: Conducting surveys among marginalized people entails methodological challenges and ethical considerations. However, continually attempting to reach marginalized people in surveys by tailoring data collection strategies to their specific life situation is essential to gain insight into their health and well-being.

Authors: Wang Ping , Shan Yuezhan , Xiao Benshan , Zhang Xiang , Hou Jianfei , Cui Ni , Cao Xianglong , Cheng Kailiang 
Published: February 2024

Objectives: To verify the anatomical basis, ideal puncture sites, and potential pitfalls of the distal radial artery (dRA) in the anatomical snuffbox region for distal radial access (dTRA). Materials and Methods: Overall, 26 formalin-fixed upper limbs and computed tomography angiography (CTA) of the upper limbs of 168 consecutive patients were studied. Cadaveric dissection and dRA 3D reconstruction were used to evaluate the dRA route for dTRA. The puncture sites, dRA diameter, and angle of the dRA and tendons of the extensor pollicis brevis were also measured in the patients and cadavers. Results: The cadaver dissection provided more insights than did the dRA 3D reconstruction. However, preoperative evaluation had better diagnostic accuracy (p=0.024). Puncture sites 1 and 3 had a high success rate (63.2% possible success rate, 191/302). The DISFAVOR theory was put forward, in which 8 types of potential pitfalls that may interrupt puncture procedure or lead to a surgical failure were observed, including occlusion, stenosis, tortuosity, arteriovenous fistula, angioma, different radial artery (RA) ramifications, radial veins, and cephalic veins. The mean diameter of dRA based on cadaver dissection and CTA was 2.53 (SD=0.73) and 2.63 (SD=0.69) mm, respectively. Furthermore, the minimum distance from the outer layer of dRA to the skin was 5.71 (SD=2.0) mm based on CTA. The angle between the dRA and tendons of extensor pollicis brevis (TEPB) based on cadaver dissection and CTA was 58.0° (SD=21.5°) and 51.8° (SD=16.6°), respectively. Conclusions: Puncture sites 1 and 3 were more suitable for the dTRA, and we put forward the DISFAVOR theory to summarize the 8 types of potential pitfalls during the use of dTRA.

Introduction: Intermittent hypoxia (IH), an important feature of obstructive sleep apnea, enhances the function of lung cancer cell-derived extracellular vesicles (EVs) to exacerbate the immunosuppressive properties of macrophages. Herein, we investigated the effects of EVs obtained from lung adenocarcinoma cells cultured under IH on macrophage polarization. Methods: The M1-type and M2-type tumor-associated macrophages (TAMs) in tissues from lung adenocarcinoma cases with (n = 10) or without (n = 12) OSA were assessed by immunohistochemical studies. EVs obtained from A549 cells grown under normoxia (EV-NA) or IH (EV-IH) were isolated and cocultured with macrophages. MicroRNA sequencing was used to determine discrepant miRNAs in EVs, selecting miR-20a-5p for subsequent experiments. Next, reverse transcription-quantitative polymerase chain reaction, flow cytometry, luciferase reporter assay, western blotting assay, and gain- and loss-of-function assays were used to explore the mechanism by which miR-20a-5p promotes M2 macrophage polarization by targeting phosphatase and Tensin homolog gene (PTEN). Results: Stromal M2 TAMs were highly abundant in patients with lung adenocarcinoma and obstructive sleep apnea. Macrophages treated with EV-IH that highly expressed miR-20a-5p showed the M2 phenotype. Luciferase reporter assay confirmed PTEN as a target of miR-20a-5p. Transfection of miR-20a-5p mimics decreased PTEN expression, upregulated M2 polarization markers, and promoted Akt phosphorylation in macrophages, while transfection with a miR-20a-5p inhibitor had the opposite effects. Furthermore, miR-20a-5p inhibition in macrophages eliminated the PTEN downregulation, Akt phosphorylation, and upregulation of M2 polarization markers induced by EV-IH transfection. Conclusion: These findings indicate that EVs obtained from lung adenocarcinoma cells cultured under IH deliver miR-20a-5p to promote M2 macrophage polarization by targeting PTEN.

Background Stroke can impair manual dexterity, leading to loss of independence following incomplete recovery. Enhancing our understanding of dexterity impairment may improve neurorehabilitation. Objectives The study aimed to measure dexterity components in acute stroke patients with and without hand motor deficits, compare them to those of healthy controls (HC), and to explore the neural substrates involved in specific components of dexterity. Methods We used the Dextrain Manipulandum to quantify fine finger force control, finger selection accuracy, coactivation, and reaction time (RT). Dexterity was evaluated twice (2 days apart) in 74 patients and 14 HC. Voxel-Lesion-Symptom-Mapping (VLSM) was used to analyze the relationship between tissue damage and dexterity. Results. Due to severe paresis or fatigue, 24 patients could not perform these tasks. In 50 patients (included 4.6 ± 3.3 days post-stroke), finger force control improved ( P < .001), as it did in HC ( P = .03) who performed better than patients on both evaluations. Accuracy of finger selection did not improve significantly in any group, but the HC performed better on both evaluations. Unexpectedly, coactivation was better in patients than in HC at D3 ( P = .03). There were no between-group differences in RT. VLSM showed that damage to the superior temporal gyrus (STG) impaired finger force control while damage to the posterior limb of the internal capsule (PLIC) impaired finger selectivity. Conclusions Acute stroke affecting the STG or PLIC impaired selective components of dexterity. Patients with mild to moderate impairment showed better finger force control and accuracy selection within 48 hours, suggesting the feasibility of detecting early dexterity improvements.
Transformations towards an integrated leadership development system—A longitudinal study in a high-performing public organization

Published: February 2024

Leadership development (LD) plays a significant role in achieving high-quality performance and business results, but there is little research on how leadership development itself evolves as the organization develops. This study explores how a leadership development system evolved over 30 years, during a time when the organization became increasingly high performing. Through reflexive thematic analysis of organizational documents and interviews with top managers and practitioners, the study provides a rich longitudinal description of the evolvement. The results revealed three pervasive changes of the leadership development system: 1) from a system for business-specific learning to one for system-wide learning; 2) from a system for personal development to one for customer-oriented quality development; and 3) from a leadership development system consisting of leadership development programs to one that is integrated into regular meetings and uses simple rules. These changes supported the gradual transformation of the leadership development from being independent to becoming integrated in the wider system, supporting the business system. The findings offer a unique insight into how an organization transitioned from individual leader development towards promoting collective aspects of leadership development. The study provides two main theoretical contributions that support the perspective of viewing leadership development as integrated within organizational development. Firstly, we present a more multifaceted way of understanding leadership development, wherein managers and employees, customer outcomes, and business advancement are seen as mutually developing. Secondly, we introduce two new critical points that complement previous descriptions of an advanced leadership development system: It is system wide (not only business specific) and customer oriented (not only leader/participant oriented).
