AbstractCarbon nanotube (CNT) has fostered research as a promising nanomaterial for a variety of applications due to its exceptional mechanical, optical, and electrical characteristics. The present article proposes a novel and comprehensive micromechanical framework to assess the viscoelastic properties of a multiscale CNT-reinforced two-dimensional (2D) woven hybrid composite. It also focuses on demonstrating the utilisation of the proposed micromechanics in the dynamic analysis of shell structure. First, the detailed constructional attributes of the proposed trans-scale composite material system are described in detail. Then, according to the nature of the constructional feature, mathematical modelling of each constituent phase or building block’s material properties is established to evaluate the homogenised viscoelastic properties of the proposed composite material system. To highlight the novelty of this study, the viscoelastic characteristics of the modified matrix are developed using the micromechanics method of Mori–Tanaka (MT) in combination with the weak viscoelastic interphase (WI) theory. In the entire micromechanical framework, the CNTs are considered to be randomly oriented. The strength of the material (SOM) approach is used to establish mathematical frameworks for the viscoelastic characteristics of yarns, whereas the unit cell method (UCM) is used to determine the viscoelastic properties of the representative unit cell (RUC). Different numerical results have been obtained by varying the CNT composition, interface conditions, agglomeration, carbon fibre volume percentage, excitation frequency, and temperature. The influences of geometrical parameters like yarn thickness, width, and the gap length to yarn width ratio on the viscoelasticity of such composite material systems are also explored. The current study also addresses the issue of resultant anisotropic viscoelastic properties due to the use of dissimilar yarn thickness. The results of this micromechanical analysis provide valuable insights into the viscoelastic properties of the proposed composite material system and suggest its potential applications in vibration damping. To demonstrate the application of developed novel micromechanics in vibration analysis, as one of the main contributions, comprehensive numerical experiments are conducted on a shell panel. The results show a significant reduction in vibration amplitudes compared to traditional composite materials in the frequency response and transient response analyses. To focus on the aspect of micromechanical behaviour on dynamic response and for the purpose of brevity, only linear strain displacement relationships are considered for dynamic analysis. These insights could inform future research and development in the field of composite materials.

Abstract
Background
The increasing burden of dengue virus on public health due to more explosive and frequent outbreaks highlights the need for improved surveillance and control. Genomic surveillance of dengue virus not only provides important insights into the emergence and spread of genetically diverse serotypes and genotypes, but it is also critical to monitor the effectiveness of newly implemented control strategies. Here, we present DengueSeq, an amplicon sequencing protocol, which enables whole-genome sequencing of all four dengue virus serotypes.

Results
We developed primer schemes for the four dengue virus serotypes, which can be combined into a pan-serotype approach. We validated both approaches using genetically diverse virus stocks and clinical specimens that contained a range of virus copies. High genome coverage (>95%) was achieved for all genotypes, except DENV2 (genotype VI) and DENV 4 (genotype IV) sylvatics, with similar performance of the serotype-specific and pan-serotype approaches. The limit of detection to reach 70% coverage was 10-100 RNA copies/μL for all four serotypes, which is similar to other commonly used primer schemes. DengueSeq facilitates the sequencing of samples without known serotypes, allows the detection of multiple serotypes in the same sample, and can be used with a variety of library prep kits and sequencing instruments.

Conclusions
DengueSeq was systematically evaluated with virus stocks and clinical specimens spanning the genetic diversity within each of the four dengue virus serotypes. The primer schemes can be plugged into existing amplicon sequencing workflows to facilitate the global need for expanded dengue virus genomic surveillance.
Investigating factors associated to HBV/HIV co-infected patients in antiretroviral treatment clinic, in Northeast Ethiopia

Published: May 2024

Abstract
Background
Existing research in Ethiopia has primarily focused on the individual epidemiology of HIV and HBV, often overlooking the intricate dynamics of co-infection. This study aims to address this gap by comprehensively exploring the prevalence of HBV and HIV co-infection and the associated factors influencing co-infection rates within the specific context of ART clinics. The existing study provides limited insights into the unique challenges posed by this dual infection in the Ethiopian population receiving ART.

Methods
An institutional-based cross-sectional study was conducted among people living with HIV aged 18 years and above attending ART clinics in northeast Ethiopia from April to May 2022. A sample size of 350(97% response rate) participants was selected by using a systematic random sampling method. Data were collected using a pre-tested interviewer-administered structured questionnaire. Data was entered into Epi Data version software and was exported to SPSS version 25 for further analysis. Descriptive statistics using Frequency, proportion, and summary measures were done. Binary logistic regressions were done to identify independent variables associated with HBV infection among HIV patients. A P-value less than 0.05 and adjusted odds ratio with a 95% confidence interval non-inclusive of one was considered statistically significant.

Results
The prevalence of Hepatitis B Surface Antigen (HBsAg) was identified constituting 7.14% of the study population. Females [AOR] 0.14; 95% Confidence Interval [CI] [0.041–0.478]). Participants with an educational status of only reading and writing (AOR 8.7; 95% CI [1.143–66.5]). Single individuals (AOR 2.04; 95% CI [1.346–28.6]) were associated factors. Moreover, participants with a viral load exceeding 1000 copies/ml were 6.5 times more likely to be infected with HBV compared to those with undetectable viral loads (AOR 6.53, 95% CI [1.87–22.72]). Additionally, individuals with a CD4 count ranging from 351 to 500 cells/ml were 1.2 times more likely to be infected with HBV compared to those with a CD4 count of 500 cells/ml or above (AOR 10.4, 95% CI [1.28-85]).

Conclusion
The prevalence of HBV infection was found to be intermediate in HIV-infected patients in the study area. Being male, marital status of single and divorced, educational level was only read and written, current viral load of > 1000 copies/ml &<1000 copies/ml, and current CD4 < 250 cells/ml were found statistically associated factors for HBV infection. Thus, we recommend the provision of routine screening for HBsAg and appropriate treatment with accurate information on risk factors for HBV to improve quality of life and reduce morbidity.
Study protocol of the GRoningen early-PD Ambroxol treatment (GREAT) trial: a randomized, double-blind, placebo-controlled, single center trial with ambroxol in Parkinson patients with a GBA mutation
Authors: Siemeling O. , Slingerland S. , van der Zee S. , van Laar T. 
Published: May 2024

Abstract
Background
To date, no disease modifying therapies are available for Parkinson’s disease (PD). Since PD is the second most prevalent neurodegenerative disorder, there is a high demand for such therapies. Both environmental and genetic risk factors play an important role in the etiology and progression of PD. The most common genetic risk factor for PD is a mutation in the GBA1(GBA)-gene, encoding the lysosomal enzyme glucocerebrosidase (GCase). The mucolytic ambroxol is a repurposed drug, which has shown the property to upregulate GCase activity in-vitro and in-vivo. Ambroxol therefore has the potency to become a disease modifying therapy in PD, which was the reason to design this randomized controlled trial with ambroxol in PD patients.

Methods
This trial is a single-center, double-blind, randomized, placebo-controlled study, including 80 PD patients with a GBA mutation, receiving either ambroxol 1800 mg/day or placebo for 48 weeks. The primary outcome measure is the Unified Parkinson’s Disease Rating Scale motor subscore (part III) of the Movement Disorder Society (MDS-UPDRSIII) in the practically defined off-state at 60 weeks (after a 12-week washout period). Secondary outcomes include a 3,4-dihydroxy-6-18F-fluoro-I-phenylalanine ([18F]FDOPA) PET-scan of the brain, Magnetic Resonance Imaging (with resting state f-MRI and Diffusion Tensor Imaging), GCase activity, both intra- and extracellularly, sphingolipid profiles in plasma, Montreal Cognitive Assessment (MoCA), quality of life (QoL) measured by the Parkinson’s Disease Questionnaire (PDQ-39) and the Non-Motor Symptom Scale (NMSS) questionnaire.

Discussion
Ambroxol up to 1200 mg/day has shown effects on human cerebrospinal fluid endpoints, which supports at least passage of the blood-brain-barrier. The dose titration in this trial up to 1800 mg/day will reveal if this dose level is safe and also effective in modifying the course of the disease.

Authors: Zhang Yan , Xu Jian , Zhang Chi , Zhang Xu , Yuan Xueli , Ni Wenqing , Zhang Hongmin , Zheng Yijin , Zhao Zhiguang 
Published: May 2024

Abstract
Background
Dementia is a leading cause of disability in people older than 65 years worldwide. However, diagnosing dementia in its earliest symptomatic stages remains challenging. This study combined specific questions from the AD8 scale with comprehensive health-related characteristics, and used machine learning (ML) to construct diagnostic models of cognitive impairment (CI).

Methods
The study was based on the Shenzhen Healthy Ageing Research (SHARE) project, and we recruited 823 participants aged 65 years and older, who completed a comprehensive health assessment and cognitive function assessments. Permutation importance was used to select features. Five ML models using BalanceCascade were applied to predict CI: a support vector machine (SVM), multilayer perceptron (MLP), AdaBoost, gradient boosting decision tree (GBDT), and logistic regression (LR). An AD8 score ≥ 2 was used to define CI as a baseline. SHapley Additive exPlanations (SHAP) values were used to interpret the results of ML models.

Results
The first and sixth items of AD8, platelets, waist circumference, body mass index, carcinoembryonic antigens, age, serum uric acid, white blood cells, abnormal electrocardiogram, heart rate, and sex were selected as predictive features. Compared to the baseline (AUC = 0.65), the MLP showed the highest performance (AUC: 0.83 ± 0.04), followed by AdaBoost (AUC: 0.80 ± 0.04), SVM (AUC: 0.78 ± 0.04), GBDT (0.76 ± 0.04). Furthermore, the accuracy, sensitivity and specificity of four ML models were higher than the baseline. SHAP summary plots based on MLP showed the most influential feature on model decision for positive CI prediction was female sex, followed by older age and lower waist circumference.

Conclusions
The diagnostic models of CI applying ML, especially the MLP, were substantially more effective than the traditional AD8 scale with a score of ≥ 2 points. Our findings may provide new ideas for community dementia screening and to promote such screening while minimizing medical and health resources.
School-aged children’s movement behaviours and subjective health complaints in Japan: a cross-sectional study during COVID-19 pandemic-related school closures and after school reopenings
Authors: Kasai Akane , Shikano Akiko , Tanaka Ryo , Yoshinaga Mari , Noi Shingo 
Published: May 2024

Abstract
Background
Social restrictions associated with the COVID-19 pandemic have altered children’s movement behaviours and impacted their mental health. However, the influence of social restrictions on subjective health complaints remains inadequately understood. This study compared adherence to 24-hour movement behaviour guidelines and the prevalence of subjective health complaints during school closure and one year after reopening. We also examined how combinations of adherence to movement behaviour recommendations relate to subjective health complaints.

Methods
A repeated cross-sectional survey was conducted at two points. The first survey in May 2020 included 1535 (766 boys and 769 girls) participants during school closures, while the second survey from May to July 2021 involved 1125 (583 boys and 542 girls) participants one year after school reopening. The questionnaire covered socio-demographics, physical activity, screen time, sleep, and subjective health complaints. Differences between periods were analysed using chi-square tests. Logistic regression models assessed the association between adherence to guidelines and subjective health complaints.

Results
During school closure, children were more likely to meet ‘only sleep’ recommendations and have irritability and lethargy symptoms. Irrespective of sex, those adhering to two or all three recommendations (excluding physical activity and screen time) had a lower risk of symptoms related to physical and mental pain, fatigue, irritability, and lethargy as compared to those who met none of the recommendations.

Conclusions
Children should meet at least one physical activity or screen time recommendation in addition to sleep recommendations for subjective health. Strategies considering the priority of each movement behaviour are crucial, even during abnormal situations, such as pandemic-related social restrictions. This study offers insightful findings concerning children’s mental health issues during unprecedented and massive disasters or crises.
Self-reported competence among advanced practice nursing students in Denmark, Finland and Norway: a cross-sectional multicentre study
Authors: Martinsen Randi , Ahlin-Søvde Sigrid , Grov Ellen Karine , Andersson Ewa K. , Gardulf Ann 
Published: May 2024

Abstract
Background
The health care systems in the Nordic countries and worldwide are under pressure due to increased longevity and a shortage of nurses. Providing nurses with a high level of education, such as advanced practice nursing, is of great importance to ensure effective, safe and high-quality care.

Aim
The aim of this study was to investigate self-reported competence using the Nurse Professional Competence Scale Short-Form for the first time among master’s students of advanced practice nursing in the Nordic countries and to relate the findings to age, work obligations, child-rearing responsibilities, level of education and clinical nursing experience.

Methods
A multicentre, cross-sectional design was used in this study conducted at five universities in Denmark, Finland and Norway. The Nurse Professional Competence Scale Short-Form consisting of six competence areas was used with a maximum score of 7 per item for the analysis of single items and a transformed scale from 14.3 to 100 for analysing the competence areas (higher score equals higher self-reported competence). Descriptive and comparative statistics were used to analyse the data.

Results
The highest mean score was found for the competence area ‘Value-based nursing care’. Students living with home-dwelling children (≤ 18 years) reported significantly higher competence in ‘Nursing care’, while students ≥33 years reported significantly higher competence in ‘Nursing care’ and ‘Value-based nursing care’. No significant differences were found between students working and those not working alongside their studies, between students with and without further nursing-related education, or between students with long and short experience as nurses.

Conclusions
The findings from this study might help to further develop curricula in advanced practice nursing master’s programmes to ensure high-quality nursing and sustainable health care in the future. Future high-quality master’s programmes might benefit from systematic collaboration between Nordic higher education institutions as also Sweden is planning master’s programme. Higher age, having children at home and working while studying should not be considered causes for concern.

Published: May 2024

Abstract
Background
Indigenous adolescents access primary health care services at lower rates, despite their greater health needs and experience of disadvantage. This systematic review identifies the enablers and barriers to primary health care access for Indigenous adolescents to inform service and policy improvements.

Methods
We systematically searched databases for publications reporting enablers or barriers to primary health care access for Indigenous adolescents from the perspective of adolescents, their parents and health care providers, and included studies focused on Indigenous adolescents aged 10–24 years from Australia, Canada, New Zealand, and United States of America. Results were analyzed against the WHO Global standards for quality health-care services for adolescents. An additional ninth standard was added which focused on cultural safety.

Results
A total of 41 studies were included. More barriers were identified than enablers, and against the WHO Global standards most enablers and barriers related to supply factors – providers’ competencies, appropriate package of services, and cultural safety. Providers who built trust, respect, and relationships; appropriate package of service; and culturally safe environments and care were enablers to care reported by adolescents, and health care providers and parents. Embarrassment, shame, or fear; a lack of culturally appropriate services; and privacy and confidentiality were common barriers identified by both adolescent and health care providers and parents. Cultural safety was identified as a key issue among Indigenous adolescents. Enablers and barriers related to cultural safety included culturally appropriate services, culturally safe environment and care, traditional and cultural practices, cultural protocols, Indigenous health care providers, cultural training for health care providers, and colonization, intergenerational trauma, and racism. Nine recommendations were identified which aim to address the enablers and barriers associated with primary health care access for Indigenous adolescents.

Conclusion
This review provides important evidence to inform how services, organizations and governments can create accessible primary health care services that specifically meet the needs of Indigenous adolescents. We identify nine recommendations for improving the accessibility of primary health care services for Indigenous adolescents.

Published: May 2024

Abstract
Background
The rapid evolution, complexity, and specialization of oncology treatment makes it challenging for physicians to provide care based on the latest and best evidence. We hypothesized that physicians would use evidence-based trusted care pathways if they were easy to use and integrated into clinical workflow at the point of care.

Methods
Within a large integrated care delivery system, we assembled clinical experts to define and update drug treatment pathways, encoded them as flowcharts in an online library integrated with the electronic medical record, communicated expectations that clinicians would use these pathways for every eligible patient, and combined data from multiple sources to understand usage over time.

Results
We were able to achieve > 75% utilization of eligible protocols ordered through these pathways within two years, with > 90% of individual oncologists having consulted the pathway at least once, despite no requirements or external incentives associated with pathway usage. Feedback from users contributed to improvements and updates to the guidance.

Conclusions
By making our clinical decision support easily accessible and actionable, we find that we have made considerable progress toward our goal of having physicians consult the latest evidence in their treatment decisions.
