Objective There is a high prevalence of concomitant coronary artery disease (CAD) and aortic stenosis (AS), and these conditions can be treated with a variety of invasive and/or percutaneous approaches. The aim of this study is to demonstrate the feasibility, efficacy, and safety of a staged transcatheter aortic valve replacement (TAVR) after a hybrid minimally invasive direct coronary artery bypass surgery (MIDCAB) to treat combined complex CAD and AS. Methods Six patients with concomitant CAD and severe AS underwent staged treatment of their CAD with MIDCAB and TAVR. All patients had significant complex left main or left anterior descending artery (LAD) stenosis deemed to be not amenable to percutaneous coronary intervention (PCI). Results The average syntax score was 22±8 and the Society of Thoracic Surgeons score for surgical AVR was 8±3%. All patients underwent a single vessel MIDCAB for revascularization of the LAD (three patients required additional PCI for non-LAD disease). Two patients had pre-TAVR balloon aortic valvuloplasty and one patient also required treatment of severe mitral valve regurgitation with percutaneous edge-to-edge repair (the MitraClip). There was no intraprocedural or hospital mortality. No neurological deficits or vascular complications were recorded. Conclusions A hybrid staged approach for combined complex CAD and severe AS with MIDCAB, PCI, and TAVR is a valid option in high-risk patients. The order and timing of these procedures must be tailored to the patient’s clinical symptoms, stability, and severity of disease.

Background: Proximal hamstring avulsions are severe tendon injuries and are commonly sports-related. Open and endoscopic techniques as well as different anchor configurations have already been described for proximal hamstring repair. Novel all-suture anchors have been developed to provide decreased bone loss during placement and reduced occupied bone volume when compared with titanium suture anchors. Hypothesis: Complete proximal hamstring avulsions repaired with all-suture anchors will demonstrate equal load to failure and comparable displacement under cyclic loading when compared with titanium suture anchors. Study Design: Controlled laboratory study. Methods: Complete proximal hamstring avulsions were created in 18 paired cadaveric specimens (mean ± SD age, 63.0 ± 10.4 years). Either all-suture anchors or titanium suture anchors were used for repair. Cyclic loading from 10 to 125 N at 1 Hz was performed for 1500 cycles with a material testing machine. Displacement was assessed along anterior and posterior aspects of the tendon repair with optical tracking. Specimens were loaded to failure at a rate of 120 mm/min. Displacement, load to failure, and repair construct stiffness were compared between matched pairs with the Wilcoxon signed-rank test. Correlations were determined by Spearman rho analysis. Results: The all-suture anchors showed significantly higher load-to-failure values when compared with the titanium anchor repairs (799.64 ± 257.1 vs 573.27 ± 89.9 N; P = .008). There was no significant difference in displacement between all-suture anchors and titanium suture anchors at the anterior aspect (6.60 ± 2.2 vs 5.49 ± 1.1 mm; P = .26) or posterior aspect (5.87 ± 2.08 vs 5.23 ± 1.37 mm; P = .678) of the repaired hamstring tendons. Conclusion: All-suture anchors demonstrated similar displacement and superior load to failure when compared with titanium suture anchors. Clinical Relevance: The results of this study suggest that all-suture anchors are an equivalent alternative to titanium suture anchors for proximal hamstring avulsion repair.

Published: January 2020

AbstractThe plasmon-induced transparency (PIT), which is destructive interference between the superradiation mode and the subradiation mode, is studied in patterned graphene-based terahertz metasurface composed of graphene ribbons and graphene strips. As the results of finite-difference time-domain (FDTD) simulation and coupled-mode theory (CMT) fitting, the PIT can be dynamically modulated by the dual-mode. The left (right) transmission dip is mainly tailored by the gate voltage applied to graphene ribbons (stripes), respectively, meaning a dual-mode on-to-off modulator is realized. Surprisingly, an absorbance of 50% and slow-light property of 0.7 ps are also achieved, demonstrating the proposed PIT metasurface has important applications in absorption and slow-light. In addition, coupling effects between the graphene ribbons and the graphene strips in PIT metasurface with different structural parameters also are studied in detail. Thus, the proposed structure provides a new basis for the dual-mode on-to-off multi-function modulators.

Abstract
Background
Interactions between transcription factors and DNA lie at the centre of many biological processes including DNA recombination, replication, repair and transcription. Most bacteria encode diverse proteins that act as transcription factors to regulate various traits. Several technologies for identifying protein–DNA interactions at the genomic level have been developed. Bind-n-seq is a high-throughput in vitro method first deployed to analyse DNA interactions associated with eukaryotic zinc-finger proteins. The method has three steps (i) binding protein to a randomised oligonucleotide DNA target library, (ii) deep sequencing of bound oligonucleotides, and (iii) a computational algorithm to define motifs among the sequences. The classical Bind-n-seq strategy suffers from several limitations including a lengthy wet laboratory protocol and a computational algorithm that is difficult to use. We introduce here an improved, rapid, and simplified Bind-n-seq protocol coupled with a user-friendly downstream data analysis and handling algorithm, which has been optimized for bacterial target proteins. We validate this new protocol by showing the successful characterisation of the DNA-binding specificities of YipR (YajQ interacting protein regulator), a well-known transcriptional regulator of virulence genes in the bacterial phytopathogen Xanthomonas campestris pv. campestris (Xcc).

Results
The improved Bind-n-seq approach identified several DNA binding motif sequences for YipR, in particular the CCCTCTC motif, which were located in the promoter regions of 1320 Xcc genes. Informatics analysis revealed that many of these genes regulate functions associated with virulence, motility, and biofilm formation and included genes previously found involved in virulence. Additionally, electromobility shift assays show that YipR binds to the promoter region of XC_2633 in a CCCTCTC motif-dependent manner.

Conclusion
We present a new and rapid Bind-n-seq protocol that should be useful to investigate DNA-binding proteins in bacteria. The analysis of YipR DNA binding using this protocol identifies a novel DNA sequence motif in the promoter regions of target genes that define the YipR regulon.

AbstractBackgroundWitches’ broom disease (WBD) of cacao (Theobroma cacaoL.), caused byMoniliophthora perniciosa, is the most important limiting factor for the cacao production in Brazil. Hence, the development of cacao genotypes with durable resistance is the key challenge for control the disease. Proteomic methods are often used to study the interactions between hosts and pathogens, therefore helping classical plant breeding projects on the development of resistant genotypes. The present study compared the proteomic alterations between two cacao genotypes standard for WBD resistance and susceptibility, in response toM. perniciosainfection at 72 h and 45 days post-inoculation; respectively the very early stages of the biotrophic and necrotrophic stages of the cacao xM. perniciosainteraction.ResultsA total of 554 proteins were identified, being 246 in the susceptible Catongo and 308 in the resistant TSH1188 genotypes. The identified proteins were involved mainly in metabolism, energy, defense and oxidative stress. The resistant genotype showed more expressed proteins with more variability associated with stress and defense, while the susceptible genotype exhibited more repressed proteins. Among these proteins, stand out pathogenesis related proteins (PRs), oxidative stress regulation related proteins, and trypsin inhibitors. Interaction networks were predicted, and a complex protein-protein interaction was observed. Some proteins showed a high number of interactions, suggesting that those proteins may function as cross-talkers between these biological functions.ConclusionsWe present the first study reporting the proteomic alterations of resistant and susceptible genotypes in theT. cacaoxM. perniciosapathosystem. The important altered proteins identified in the present study are related to key biologic functions in resistance, such as oxidative stress, especially in the resistant genotype TSH1188, that showed a strong mechanism of detoxification. Also, the positive regulation of defense and stress proteins were more evident in this genotype. Proteins with significant roles against fungal plant pathogens, such as chitinases, trypsin inhibitors and PR 5 were also identified, and they may be good resistance markers. Finally, important biological functions, such as stress and defense, photosynthesis, oxidative stress and carbohydrate metabolism were differentially impacted withM. perniciosainfection in each genotype.

Abstract
Background
Childbirth remains a uniquely multifaceted, mental-cognitive and a major life experience to women. It is composed of a variety of psycho social and emotional aspects and creates memories, sometimes bad experiences and unmet expectations which leaves the mother with lasting scars. Therefore, this study aimed at exploring post-caesarean section delivered mothers experiences of midwifery care in a public hospital in Ghana.

Methods
This descriptive exploratory qualitative research used an interpretative approach to explore mothers’ experiences of midwifery care immediately before and after caesarean section (CS). The study employed a purposive sampling technique in recruiting 22 participants who had knowledge of the phenomenon under study. Data collection was guided by an interview guide, which involved face to face individual interviews and focus group discussion at the postnatal ward and clinic. All interviews were audio-recorded and lasted 30–40 min. Audio recordings were transcribed verbatim and inductive thematic data analysis employed.

Results
Four major themes emerged from the analysis of participants’ transcripts: Support by Midwives (physical and psychological, and attitude towards patients’ pain management); Protection of mothers (provision of privacy, confidentiality and physical environment); Provision of information/communication (before caesarean section, and before a minor task) and midwives’ attitude (attitude towards delivery care).

Conclusion
Mothers delivered by caesarean section had varied experiences of midwifery care which were both positive and negative ones. Provision of psychological support and adequate pain management were positive experiences. The challenges experienced were related to provision of information, privacy, and physical support. Participants, who underwent emergency CS in particular, were dissatisfied with the provision of information concerning the surgical procedure. Provision of privacy and physical support were also issues of great concern. We therefore, recommend supportive and sensitive midwifery care particularly for mothers undergoing emergency CS. Documenting women’s diverse experiences of midwifery care before and after CS delivery is important to healthcare providers, hospital managers and policy makers as the feedback garnered can be used to improve maternity services and inform decisions on midwifery care.

Abstract
Background
The occurrence of a mediastinal germ cell tumor (GCT) and hematological malignancy in the same patient is very rare. Due to its rarity, there have been only two reports of the concurrent cases undergoing detailed genetic analysis with whole-exome sequencing (WES), and the possible clonal relationship between the both tumors remained not fully elucidated.

Methods
We performed whole-exome sequencing analysis of mediastinal GCT and acute myeloid leukemia (AML) samples obtained from one young Japanese male adult patient with concurrent both tumors, and investigated the possible clonal relationship between them.

Results
Sixteen somatic mutations were detected in the mediastinal GCT sample and 18 somatic mutations in the AML sample. Mutations in nine genes, including TP53 and PTEN both known as tumor suppressor genes, were shared in both tumors.

Conclusions
All in our case and in the previous two cases with concurrent mediastinal GCT and AML undergoing with whole-exome sequencing analysis, TP53 and PTEN mutations were commonly shared in both tumors. These data not only suggest that these tumors share a common founding clone, but also indicate that associated mediastinal GCT and AML harboring TP53 and PTEN mutations represent a unique biological entity.

Published: January 2020

AbstractBackgroundDepression is common among people with schizophrenia and associated with severe positive and negative symptoms, higher rates of disability, treatment resistance and mortality related to suicide, physical and drug-related causes. However, to our knowledge, no study has been conducted to report the magnitude of depression among people with schizophrenia in Ethiopia. Therefore, this study aimed to determine the prevalence and associated factors of depression among people with schizophrenia.MethodA hospital-based cross-sectional study was conducted among 418 patients with schizophrenia selected by systematic sampling technique. Patient Health Questionnaire 9 (PHQ-9) was used to measure depression among the study participants. To identify the potential contributing factors, we performed binary and multivariable logistic regression analysis adjusting the model for the potential confounding factors. Odds ratios (OR) with the corresponding 95% confidence interval (95%CI)) was determined to evaluate the strength of association.ResultThe prevalence estimate of depression among people with schizophrenia was found to be 18.0% [95% confidence interval: 14.50–22.30]. Our multivariable analysis revealed that current substance use (AOR 2.28, 95%CI (1.27, 4.09), suicide attempt (AOR 5.24, 95%CI (2.56, 10.72), duration of illness between 6 and 10 years (AOR 2.09, 95%CI (1.08, 4.04) and poor quality of life (AOR 3.13, 95%CI (1.79, 5.76) were found to be the factors associated with depression among people with schizophrenia.ConclusionThe current study revealed that comorbid depression was high among people with schizophrenia and associated with current substance use, suicide attempt, and long duration of the illness as well as poor quality of life. Attention needs to be given to address comorbid depression among people with schizophrenia.

AbstractBackgroundPrimary care patients with prediabetes is a priority group in the clinical, organisational and policy contexts. Engaging in regular physical activity is crucial to prevent diabetes for this group. The objectives of the study were to assess factors associated with meeting the recommendation of at least 150 min of moderate/vigorous physical activity weekly, and to explore facilitators and barriers related to the behaviour among primary care patients with prediabetes in Singapore.MethodsThis was a mixed methods study, consisting of a cross-sectional survey involving 433 participants from 8 polyclinics, and in-depth interviews with 48 of them. Adjusted prevalence ratios (aPR) were obtained by mixed effects Poisson regression model. The socio-ecological model (SEM) was applied, and thematic analysis performed.ResultsThe prevalence of meeting the recommendation was 65.8%. This was positively associated with being male (aPR 1.21, 95%CI 1.09–1.34), living in 4–5 room public housing (aPR 1.19, 95%CI 1.07–1.31), living in executive flat/private housing (aPR 1.26, 95%CI 1.06–1.50), having family members/friends to exercise with (aPR 1.57, 95%CI 1.38–1.78); and negatively associated with a personal history of osteoarthritis (aPR 0.75, 95%CI 0.59–0.96), as well as time spent sitting or reclining daily (aPR 0.96, 95%CI 0.94–0.98). The recurrent themes for not meeting the recommendation included lacking companionship from family members/friends, medical conditions hindering physical activity (particularly osteoarthritis), lacking knowledge/skills to exercise properly, “no time” to exercise and barriers pertaining to exercise facilities in the neighbourhood. The recurrent themes for meeting the recommendation included family/peer influence, health/well-being concerns and education by healthcare professionals.ConclusionsMuch more remains to be done to promote physical activity among primary care patients with prediabetes in Singapore. Participants reported facilitators and barriers to physical activity at different levels of the SEM. Apart from the individual and interpersonal levels, practitioners and policy makers need to work together to address the organisational, community and policy barriers to physical activity.
Work-family balance and the subjective well-being of rural women in Sichuan, China

Published: January 2020

Abstract
Background
Due to the great burden of family and the conflicts among family, society and career roles resulting from migrant working, rural women suffer more conflicts between work and family and need more social attention. Previous studies of the conflicts between family and work mainly focus on the group of career women, and there is a lack of the research on the conflicts between work and family of rural women, which needs to be systematically and further studied.

Methods
This study used a sample survey of 380 rural women in rural areas of Sichuan Province to measure rural women’s cognition of work-family, coordination and handling of conflicts, post-conflict choices, and subjective well-being; the study constructs an ordered multi-class logistic regression model to explore the impact of work-family conflict on the subjective well-being of rural women in rural regions.

Results
The study result shows that: (1) The level of subjective well-being of rural women is generally high, and 70% of women feel satisfied or very satisfied. (2) The factor which impacts the subjective well-being among rural women most is work-interfering-with-family conflict, followed by work-family balance and confidence in conflict coordination.

Conclusion
This study can enhance our understanding of rural women in rural areas, and provide a reference for formulating policies to improve people’s life satisfaction.
Advanced practice nurses in primary care in Switzerland: an analysis of interprofessional collaboration
Authors: Josi Renata , Bianchi Monica , Brandt Sophie Karoline 
Published: January 2020

Abstract
Background
The increase in the number of chronically ill patients due to ageing is calling existing models of primary care (PC) into question. New care models have recently been implemented in Swiss PC and involve interprofessional teams. This paper aimed to investigate the practice of interprofessional collaboration between advanced practice nurses, registered nurses, and medical practice assistants within new models of PC in Switzerland using the National Interprofessional Competency Framework.

Methods
An ethnographic design comprising semi-structured interviews and non-participant observations was conducted. Sixteen interviews were conducted with care providers at their PC practice. Interviewees included four advanced practice nurses, two registered nurses, six medical practice assistants, and four general practitioners. Nine other health professionals were subsequently observed in their practice. Interviews and observations were conducted by the first author from February to April 2019.

Results
Our analysis of interview and observational data confirmed that role clarification, team functioning, collaborative leadership, interprofessional conflict resolution, patient-centered care, and interprofessional communication have a significant influence on the interprofessional collaboration among health professionals in Swiss PC. Among these domains, role clarification and team functioning were the most frequently raised issues. Both were found to have the potential to negatively influence and, therefore, hinder efficient interprofessional collaboration within PC.

Conclusion
From the analysis, it emerged that role clarification is crucial for effective interprofessional collaboration within new care delivery models in the Swiss PC context. Our study results may inform international health policymakers and practitioners about six important domains of interprofessional care when implementing new care models. Practical experience with new models of care involving advanced practice nurses and medical practice assistants may also influence the regulation of the scope of practice of these health professionals in Switzerland.
