Effects of a nurse-led Tai Chi programme on improving quality of life, mental wellbeing, and physical function of women with breast cancer: Protocol for a randomized controlled trial
Authors: Wang Carol Chunfeng , Geraghty Sadie , Fox-Harding Caitlin , Wang Calvin 
Published: September 2022

Objectives: Quality of life, mental wellbeing, and physical function deteriorate among women with breast cancer. Tai Chi is a moderate form of exercise that may be effective in improving the mental and physical wellbeing, therefore, the quality of life of women with breast cancer. This protocol paper outlines a trial to determine the therapeutic effects of a Tai Chi programme on breast cancer management. Methods: The study will be an interventional, single-blind, double-armed, randomized, and controlled trial involving a 12-week Tai Chi programme for women with breast cancer. Forty participants aged 18 years and above who are diagnosed with breast cancer from the general community will be recruited. All participants will be randomized to either a Tai Chi programme or a waiting list control group. The Tai Chi programme will involve 12 weeks of group Tai Chi sessions, with 45 min per session, twice a week. The primary outcome will be potential improvements to the quality of life, and secondary outcomes will be potential improvements in mental wellbeing (anxiety and depression), and physical function (pain, flexibility, obesity, and vital signs). These outcomes will be assessed via self-administered online assessments and physical examinations pre-and post-intervention. Linear mixed modelling will be used to assess changes in outcomes. Discussion and dissemination: Tai Chi is a safe, easy to learn, inexpensive, and low-intensity exercise with increasing popularity worldwide. If the intervention improves the quality of life in women with breast cancer, this study will build research capacity and increase awareness of the potential for Tai Chi to empower patients and engage them in self-management of breast cancer symptoms. Research findings will be disseminated to the public, health professionals, researchers, and healthcare providers through conference presentations, lay summaries, and peer-reviewed publications.

Published: September 2022

The aim of this study was to determine the clinical and radiographic outcomes and survivorship of the ISIS® (Evolutis™, Briennon, France) trapeziometacarpal prosthesis at a minimum follow-up of 5 years. Of the 77 implants (66 patients) reviewed at a mean follow-up of 107.5 months, pain and function had improved significantly. Fourteen cups (19%) and three stems (4%) appeared to have loosened on radiographs. Loosening occurred more often with cemented cups than screwed cups ( p = 0.0342). In five cases, the prosthesis was removed and revised by trapeziectomy and interposition: four were cemented cups (three loosening, one trapezium fracture) and one was a loosened metacarpal stem. A single case of dislocation occurred during the follow-up period. The survival rate was 94% (95% CI: 85 to 97). The ISIS® prosthesis is a reliable implant for treating disabling thumb basal joint arthritis, with a low complication rate and long-lasting clinical and functional improvements. Using a screwed trapezial cup instead of a cemented one appears to prevent loosening and the need for surgical revision. Level of evidence: IV
Residual flexion deformity after scaphoid nonunion surgery: 7-year follow-up study
Authors: Schriever Thorsten , Wilcke Maria 
Published: September 2022

The clinical implication of a residual flexion deformity following surgery for scaphoid nonunion is unclear. Sixty-three patients who underwent scaphoid nonunion surgery were assessed after a mean of 7 years (range 5–10) to analyse the outcomes based on the presence of residual scaphoid deformity. Primary outcome was Disabilities of the Arm, Shoulder and Hand score. Secondary outcomes were Patient-Rated Wrist Evaluation score, wrist range of motion and strength. Patients were dichotomized to residual deformity or no deformity. Scaphoid deformity was calculated from CT scans based on the median difference between the height–length ratio of the operated versus the uninjured scaphoid. There were no differences between residual deformity ( n = 33) and no deformity ( n = 30) in any outcome variables, except for wrist extension which was slightly worse in the deformity group. The deformity group had a greater number of radiographic osteoarthritis, but all cases were mild, and osteoarthritis did not correlate to a worse outcome. We conclude that residual scaphoid deformity has no relevant negative impact on mid-term wrist function. Level of evidence: IV

Authors: Nguyen Mindy , Bixby Sarah , Yen Yi-Meng , Miller Patricia , Stracciolini Andrea 
Published: September 2022

Background: There is a known association between ice hockey and cam deformity in growing athletes. Similarly, the association between sport specialization and overuse injury in youth athletes has been well established. Limited research exists examining the relationship between cam deformity and sport specialization. Hypothesis/Purpose: Our hypothesis was that there would be a positive association with cam deformity and sport specialization category. Study Design: Retrospective chart review and cross-sectional questionnaire study. Level of Evidence: Level 4. Methods: Study participants included athletes aged 15 to 25 years with symptomatic femoroacetabular impingement (FAI) and considered ice hockey as their primary sport. All participants had completed Dunn lateral radiographs or hip magnetic resonance imaging as part of their clinical evaluation. All participants completed a survey regarding sport specialization level. Multivariable linear regression analysis controlling for sex was used to analyze the association between degree of sport specialization, age of sport specialization, position played, and level played. Comparisons in radiographic parameters across ice hockey groups were conducted using Student t tests and chi-square tests. Results: Sixty-six ice hockey participants made up the cohort. The majority reported high sport specialization (41/66, 62%). The mean age of sport specialization was 10.7 years (SD 3.5). Participants with moderate specialization had 25 times the odds of a cam deformity (odds ratio [OR] 25.2; 95% CI 1.5-410.7; P = 0.02) and those with high specialization had 9 times the odds of cam deformity (OR 9.3; 95% CI 1.2-74.2; P = 0.04) compared with those with a low degree of specialization, controlling for patient sex. No association was detected between the age of specialization and the likelihood of cam deformity when controlling for patient sex. Conclusion: Level of sport specialization was associated with a cam deformity in this cohort of youth ice hockey athletes. Clinical Relevance: This study suggests that an association exists.

Published: September 2022

Background: Student-run health initiatives in the community setting have been utilized to provide practical experience for undergraduate students to develop professional competencies, gain exposure to diverse populations, and to engage in activities of social accountability. There is much literature on student-run health initiatives; however, there is no consensus on a definition of this concept or a comprehensive synthesis of the literature that describes student-run health initiatives offered by students in pre-licensure healthcare education programs. Purpose: To provide a concept analysis of, and propose a definition for, student-run health initiatives that provide community-based services for students during pre-licensure health discipline education. Methods: A systematic literature search and review process was used to identify and synthesize peer-reviewed articles from 7 academic databases covering a range of pre-licensure health disciplines and education. Walker and Avant’s framework for concept analysis was used to guide exploration of attributes, antecedents and consequences of student-run initiatives, and to inform development of a definition for this concept. Results: The review yielded 222 articles for data extraction and represented 17 distinct pre-licensure health disciplines, 18 health-related disciplines, and a range of other baccalaureate and graduate programs. Our analysis revealed 16 definitions, 5 attributes, 6 antecedents, and consequences identified for student-run health initiatives. Attributes were Provision of Service, Service is Free, Target Clientele, Volunteerism, and Student Governance. Antecedents included Purpose/Rationale, Affiliation with Academic Unit, Location and Partnerships, Funding and Resources, Professional Oversight, and Preparation for Student Role. Consequences were improved access to services and outcomes for clients; competency development, personal gains and interprofessional learning for students; and positive outcomes for broader systems, such as decrease of service utilization and cost/benefit. Conclusions: There was no clear conceptual definition for student-run health initiatives, but many defining characteristics and well-described exemplars in the literature. Given the variations in purpose and scope of these initiatives, particularly to distinguish degree of students’ roles in operations and the involvement of academic institutions, we propose 3 distinct conceptual definitions: student-run, student-led, and student-infused health initiatives.

Published: September 2022

Abstract
Background
Fragile X syndrome (FXS) is the most common inherited form of neurodevelopmental disability. It is often characterized, especially in males, by intellectual disability, anxiety, repetitive behavior, social communication deficits, delayed language development, and abnormal sensory processing. Recently, we identified electroencephalographic (EEG) biomarkers that are conserved between the mouse model of FXS (Fmr1 KO mice) and humans with FXS.

Methods
In this report, we evaluate small molecule target engagement utilizing multielectrode array electrophysiology in the Fmr1 KO mouse and in humans with FXS. Neurophysiologic target engagement was evaluated using single doses of the GABAB selective agonist racemic baclofen (RBAC).

Results
In Fmr1 KO mice and in humans with FXS, baclofen use was associated with suppression of elevated gamma power and increase in low-frequency power at rest. In the Fmr1 KO mice, a baclofen-associated improvement in auditory chirp synchronization was also noted.

Conclusions
Overall, we noted synchronized target engagement of RBAC on resting state electrophysiology, in particular the reduction of aberrant high frequency gamma activity, across species in FXS. This finding holds promise for translational medicine approaches to drug development for FXS, synchronizing treatment study across species using well-established EEG biological markers in this field.

Trial registration

A statistical network pre-processing method to improve relevance and significance of gene lists in microarray gene expression studies
Authors: Agapito Giuseppe , Milano Marianna , Cannataro Mario 
Published: September 2022

Abstract
Background
Microarrays can perform large scale studies of differential expressed gene (DEGs) and even single nucleotide polymorphisms (SNPs), thereby screening thousands of genes for single experiment simultaneously. However, DEGs and SNPs are still just as enigmatic as the first sequence of the genome. Because they are independent from the affected biological context. Pathway enrichment analysis (PEA) can overcome this obstacle by linking both DEGs and SNPs to the affected biological pathways and consequently to the underlying biological functions and processes.

Results
To improve the enrichment analysis results, we present a new statistical network pre-processing method by mapping DEGs and SNPs on a biological network that can improve the relevance and significance of the DEGs or SNPs of interest to incorporate pathway topology information into the PEA. The proposed methodology improves the statistical significance of the PEA analysis in terms of computed p value for each enriched pathways and limit the number of enriched pathways. This helps reduce the number of relevant biological pathways with respect to a non-specific list of genes.

Conclusion
The proposed method provides two-fold enhancements. Network analysis reveals fewer DEGs, by selecting only relevant DEGs and the detected DEGs improve the enriched pathways’ statistical significance, rather than simply using a general list of genes.
Risk stratification and pathway analysis based on graph neural network and interpretable algorithm
Authors: Liang Bilin , Gong Haifan , Lu Lu , Xu Jie 
Published: September 2022

Abstract
Background
Pathway-based analysis of transcriptomic data has shown greater stability and better performance than traditional gene-based analysis. Until now, some pathway-based deep learning models have been developed for bioinformatic analysis, but these models have not fully considered the topological features of pathways, which limits the performance of the final prediction result.

Results
To address this issue, we propose a novel model, called PathGNN, which constructs a Graph Neural Networks (GNNs) model that can capture topological features of pathways. As a case, PathGNN was applied to predict long-term survival of four types of cancer and achieved promising predictive performance when compared to other common methods. Furthermore, the adoption of an interpretation algorithm enabled the identification of plausible pathways associated with survival.

Conclusion
PathGNN demonstrates that GNN can be effectively applied to build a pathway-based model, resulting in promising predictive power.
A pan-cancer analysis of collagen VI family on prognosis, tumor microenvironment, and its potential therapeutic effect
Authors: Li Xiang , Li Zeng , Gu Shanzhi , Zhao Xinhan 
Published: September 2022

Abstract
Background
Collagen VI family (COL6A) is a major member of extracellular matrix protein. There is accumulating evidence that COL6A is involved in tumorigenesis and tumor progression. In this study, we performed a systematic analysis of COL6A in pan-cancer based on their molecular features and clinical significance.

Methods
Based on updated public databases, we integrated several bioinformatics analysis methods to investigate the expression levels of COL6A as well as the relationship between their expression and patient survival, immune subtypes, tumor microenvironment, stemness scores, drug sensitivity, and DNA methylation.

Results
The expression levels of COL6A members varied in different cancers, suggesting their expression was cancer-dependent. Among COL6A members, COL6A1/2/3 were predicted poor prognosis in specific cancers. Furthermore, COL6A1/2/3 expression levels revealed a clear correlation with immune subtypes, and COL6A1/2/3 were associated with tumor purity, that is, gene expression levels were generally higher in tumors with higher stromal scores and immune scores. COL6A1/2/3 had a significantly negative correlation with RNA stemness scores, and meanwhile they were also related to DNA stemness scores in different degrees. In addition, the expression of COL6A1/2/3 was significantly related to drug sensitivity of cancer cells. Finally, our study revealed that COL6A1/2/3 expression was mainly negatively correlated with gene methylation, and the methylation levels showed remarkable differences in various cancers.

Conclusions
These findings highlight both the similarities and differences in the molecular characteristics of COL6A members in pan-cancer, and provide comprehensive insights for further investigation into the mechanism of COL6A.
Genomic distribution and context dependent functionality of novel WRKY transcription factor binding sites
Authors: Arndt Laureen Christin , Heine Susanne , Wendt Lino , Wegele Emilia , Schomerus Jan Titus , Schulze Jutta , Hehl Reinhard 
Published: September 2022

Abstract
Background
The WT-boxes NGACTTTN are novel microbe-associated molecular pattern (MAMP)-responsive cis-regulatory sequences. Many of them are uncommon WRKY transcription factor (TF) binding sites.

Results
To understand their functional relevance, a genomic distribution analysis of the 16 possible WT-boxes and a functional analysis of a WT-box rich promoter was done. The genomic distribution analysis shows an enrichment of specific WT-boxes within 500 bp upstream of all Arabidopsis thaliana genes. Those that harbour a T 5′ to the core sequence GACTTT can also be part of the classic WRKY binding site the W-box TTGACT/C. The MAMP-responsive gene ATEP3, a class IV chitinase, harbours seven WT-boxes within its 1000 bp upstream region. In the context of synthetic promoters, the four proximal WT-boxes confer MAMP responsivity while the three WT-boxes further upstream have no effect. Rendering the nucleotides adjacent and in the vicinity of the WT-box core sequence reveals their functional importance for gene expression. A 158 bp long ATEP3 minimal promoter harbouring the two WT-boxes CGACTTTT, confers WT-box-dependent basal and MAMP-responsive reporter gene expression. The ATEP3 gene is a proposed target of WRKY50 and WRKY70. WRKY50 negatively regulates MAMP responsivity of the two WT-boxes CGACTTTT, while WRKY70 activates gene expression in a WT-box dependent manner. Both WRKY factors bind directly to the WT-box CGACTTTT.

Conclusion
In summary, WT-boxes are enriched in promoter regions and comprise novel and uncommon WRKY binding sites required for basal and MAMP-induced gene expression. WT-boxes not being part of a W-box may be a missing link for WRKY target gene prediction when these genes do not harbour a W-box.

Published: September 2022

Abstract
Background
Broomcorn millet is highly tolerant to drought and barren soil. Changes in chlorophyll content directly affect leaf color, which subsequently leadsleading to poor photosynthetic performance and reduced crop yield. Herein, we isolated a yellow leaf mutant (YX-yl) using a forward genetics approach and evaluated its agronomic traits, photosynthetic pigment content, chloroplast ultrastructure, and chlorophyll precursors. Furthermore, the molecular mechanism of yellowing was explored using transcriptome sequencing.

Results
The YX-yl mutant showed significantly decreased plant height and low yield. The leaves exhibited a yellow-green phenotype and poor photosynthetic capacity during the entire growth period. The content of chlorophyll a, chlorophyll b, and carotenoids in YX-yl leaves was lower than that in wild-type leaves. Chlorophyll precursor analysis results showed that chlorophyll biosynthesis in YX-yl was hindered by the conversion of porphobilinogen to protoporphyrin IX. Examination of chloroplast ultrastructure in the leaves revealed that the chloroplasts of YX-yl accumulated on one side of the cell. Moreover, the chloroplast structure of YX-yl was degraded. The inner and outer membranes of the chloroplasts could not be distinguished well. The numbers of grana and grana thylakoids in the chloroplasts were low. The transcriptome of the yellowing mutant YX-yl was sequenced and compared with that of the wild type. Nine chlorophyll-related genes with significantly different expression profiles were identified: PmUROD, PmCPO, PmGSAM, PmPBDG, PmLHCP, PmCAO, PmVDE, PmGluTR, and PmPNPT. The proteins encoded by these genes were located in the chloroplast, chloroplast membrane, chloroplast thylakoid membrane, and chloroplast matrix and were mainly involved in chlorophyll biosynthesis and redox-related enzyme regulation.

Conclusions
YX-yl is an ideal material for studying pigment metabolism mechanisms. Changes in the expression patterns of some genes between YX-yl and the wild type led to differences in chloroplast structures and enzyme activities in the chlorophyll biosynthesis pathway, ultimately resulting in a yellowing phenotype in the YX-yl mutant. Our findings provide an insight to the molecular mechanisms of leaf color formation and chloroplast development in broomcorn millet.
Health care professionals’ perspectives on the utilisation of a remote surveillance and care tool for patients with COVID-19 in general practice: a qualitative study
Authors: Hoffmann Mariell , Stengel Sandra , Szecsenyi Joachim , Peters-Klimm Frank 
Published: September 2022

Abstract
Background
Most COVID-19 patients with severe symptoms are treated in hospitals. General practices are responsible for assessing most ambulatory patients. However, they face several challenges managing COVID-19 patients, and those with non-COVID-19 conditions. In April of 2020, we designed a software tool for the structured surveillance of high-risk home-quarantined COVID-19 patients in general practice (CovidCare) including several telephone monitorings, in order to support general practices and early identification of severe courses. This study presents the qualitative results of a mixed-methods process evaluation study on CovidCare.

Methods
In a qualitative process evaluation study conducted between March and May 2021, we explored the perspectives of seven general practitioners (GPs) and twelve VERAHs (medical care assistants with special training) on CovidCare using semi-structured interviews based on the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance). We used deductive qualitative content analysis employing the RE-AIM framework to assess the utilisation and implementation of CovidCare.

Results
Overall, most health care professionals were satisfied with CovidCare. They highlighted 1) a good orientation for the management of COVID-19 patients, especially due to a high level of uncertainty at the beginning of the pandemic, 2) the possibility to gain new knowledge, and 3) the structured data collection as facilitators for the implementation of CovidCare. Moreover, CovidCare reduced the workload for GPs while some VERAHs perceived a higher workload as they were responsible for large parts of the CovidCare management. However, CovidCare positively affected the VERAHs’ job satisfaction as most patients provided positive feedback and felt less anxious about coping with their disease. Previous experience with the software and an easy integration into daily practice were considered to be crucial utilisation drivers. Time and personnel resources were identified as major barriers. To further improve CovidCare, participants suggested a less comprehensive version of CovidCare, the expansion of inclusion criteria as well as an app for the patients’ self-management.

Conclusion
The COVID-19 surveillance and care tool for COVID-19 patients with increased risk was perceived as useful by GPs and VERAHs. Supportive remote health care tools such as CovidCare are a viable means to maintain comprehensive and continuous health care during a pandemic and may strengthen the primary care system.
