Abstract
Background
Attachment and support from family and friends are core to the experiences of ageing for older adults. The purpose of this study is to examine the relationships between attachment styles and hope, religiosity, and life satisfaction and provide new knowledge that may assist future planning for a rapidly ageing global population.

Methods
In this cross-sectional study, 504 Iranian older adult participants from Qazvin province were recruited between December 2015 and April 2016. They completed a questionnaire that included the Revised Adult Attachment Scale, the Life Satisfaction Index-Z, and the Herth Hope Index.

Results
Participants in the study had a mean age of 66.20 years (SD: 5.76) and most of them were women (57.5%). A mediation model testing the direct relationships between attachment, hope, religiosity, and life satisfaction showed a positive relationship between close attachment and religiosity (β = .226, p < .001) and a negative relationship between anxiety attachment and religiosity (β =  − .229, p < .001). Religiosity was positively related to hope (β = .384, p < .01) and hope was related to life satisfaction (β = .448, p < .001). Religiosity and hope mediated the relationship between close attachment (β = .119, p < .001) and anxiety attachment (β =  − .056, p < .01) with life satisfaction. More specifically, while religiosity and hope fully mediated the relationship between close attachment and life satisfaction, they partially mediated the attachment anxiety-life satisfaction link.

Conclusions
Findings of the study provide insight into only a narrow perspective of life satisfaction and attachment given the many and varied variables that influence these constructs. Future research is needed whereby other related variables are introduced into the model to be examined further.

Abstract
Background
The Western Pacific region constitutes one-quarter of the world’s population and has diverse health needs. While dialogue on and promotion of advanced practice nurses are ongoing, this study investigated the current responsibilities of nurses in advanced roles, future healthcare needs, and the implications of these components for nurses’ professional development within the Western Pacific region.

Methods
This study employed three phases, a descriptive survey on the current status of nurses in advanced roles in the Western Pacific region, followed by a Delphi survey, and exploratory interviews. A total of 55 national experts with clinical, academic, and/or government-related backgrounds from 18 countries participated from December 2017 – December 2018. The descriptive survey via email to identify the status of nurses in advanced roles and a working definition was developed. This formed the basis for the Delphi survey, which identified key barriers and challenges for enhancing the development of nurses in advanced roles within the country (round 1) and for the region (rounds 2 and 3). Lastly, semi-structured individual interviews were conducted to identify strategies for establishing nurses in advanced roles to improve equitable access to healthcare.

Results
Thirty-seven roles and characteristics were identified and categorized for nurses performing advanced roles. Emergency care, critical care, elderly health, child health, and rural/remote communities were identified as fields with particular need for nurses in advanced roles in the Western Pacific region. Providing effective services, influencing government leadership, and advocating for health system sustainability were deemed necessary to improve equitable healthcare access. We found that nurses in advanced roles are not limited to clinical tasks within the hospital but are poised for active participation in primary healthcare, education/teaching, professional leadership, quality management, and research.

Conclusions
Demand for nurses in advanced roles is high in the Western Pacific region and 15 items were identified across five core strategic areas to enhance development of nurses in advanced roles. Governmental-level recommendations include establishing legislative protection, improving systems for remuneration, strengthening supportive channels, and conducting national needs assessments.

Abstract
Background
General practitioners are the gatekeepers of the health of the residents. This study aims to evaluate the trend and equity of general practitioners' allocation from 2012 to 2017 in China and provide a reference for regional health planning and rational distribution of general practitioners.

Methods
We extracted the data of general practitioners from 22 provinces, 5 autonomous regions, and 4 municipalities of mainland China. The population and geographical area were taken from the China Statistical Yearbook. The general practitioners' data were taken from the China Health Statistical Yearbook. Lorenz curve, Gini coefficient, and agglomeration degree were used to analyze the data.

Results
The number of general practitioners was 252,717 in 2017, which equates to 1.82 per 10,000 residents, and accounts for 7.45% of the total number of practicing (assistant) doctors. From 2012 to 2017, the population-based Gini coefficient for general practitioners reduced from 0.31 to 0.24, while the geographical area-based Gini coefficient remained unchanged at 0.73. The agglomeration degree based on population increased from 0.72 to 0.73 in the western region including Tibet (0.403) and Shaanxi (0.513). Moreover, in the eastern region the agglomeration degree reduced from 1.477 to 1.329. In the middle region it rose from 0.646 to 0.802. The agglomeration degree based on the geographical area in the western region increased from 0.270 to 0.277 while the values in Tibet, Qinghai, Xinjiang were less than 0.1. In the eastern region, it reduced from 1.447 to 1.329. It increased from 1.149 to 1.423 in the middle region.

Conclusions
The number of general practitioners has increased significantly in China. It has a fair allocation based on population. However, the equity based on geographical area is low and uneven in different regions with large regional differences. In the western region, there is an allocation shortage with respect to population and geographical area. Concerned departments should establish and improve the incentive and performance appraisal mechanisms of general practitioners. The Internet + should be used to empower their service capacity and efficiency. The educational input should be increased for the western region and government should encourage the eastern region to support the western region.
Drug resistance and Cancer stem cells

Published: February 2021

AbstractTherapy resistance is a major problem when treating cancer patients as cancer cells develop mechanisms that counteract the effect of therapeutic compounds, leading to fit and more aggressive clones that contribute to poor prognosis. Therapy resistance can be both intrinsic and/or acquired. These are multifactorial events, and some are related to factors including adaptations in cancer stem cells (CSCs), epithelial-mesenchymal transition (EMT), deregulation of key signaling pathways, drug efflux through ABC transporters, acquired mutations, evading apoptosis, and activation of DNA damage response among others. Among these factors, CSCs represent the major source of therapy resistance. CSCs are a subset of tumor cells that are capable of self-renewal and multilineage progenitor expansion that are known to be intrinsically resistant to anticancer treatments. Multiple clones of CSCs pre-exist, and some can adopt and expand easily to changes in the tumor microenvironment (TME) and/or in response to radio- and chemotherapy. A combination of both intrinsic and extrinsic factors contributes to CSC-mediated therapy resistance. In this review, we will focus on CSCs and therapy resistance as well as suggest strategies to eliminate CSCs and, therefore, overcome resistance.

AbstractBackgroundThe home environment is a central and modifiable influence on the development of childhood obesity. Evidence supports the central role of parents in shaping problematic child eating behaviors and excess weight. Most studies of feeding emphasize parent-driven influences without taking into account the child’s role in eating interactions. Few studies have addressed the bi-directional nature of feeding dynamics in studies of young children.MethodsThe goals of this study were: 1) to examine if parental feeding styles during preschool (4–5 years) predict child weight status at 7–9 years, and 2) to examine the direction of effects between parental feeding styles and child weight status over time. Participants were part of a larger longitudinal study of Hispanic Head Start families living in the West South Central United States. Data from mother/child dyads were collected at three time points: Time 1 (ages 4–5), Time 2 (ages 5 ½-6 ½), and at Time 3 (ages 7–9). Only data from the Times 1 and 3 were used in the current analyses. A total of 128 mothers and their children had data on all variables needed for the analyses. Assessments included parent-reported feeding styles, feeding practices, acculturation, child eating behaviors, and child height and weight. Hierarchical regression was used to examine the first aim; a cross-lagged panel analysis examined the second aim.ResultsAn indulgent parental feeding style at ages 4–5 was associated with increased child BMIz-score at ages 7–9. Indulgent feeding significantly contributed to child BMIz-score beyond demographics, baseline child BMIz-score, parental acculturation, and child eating behaviors. Regarding the direction of effects in parental feeding interactions, the cross-lagged analyses showed that both indulgent feeding style and authoritative feeding style at Time 1 positively predicted child BMIz-scores at Time 3. Child effects were significant as well. Child BMIz-score at Time 1 positively predicted indulgent feeding and negatively predicted authoritarian feeding at Time 3.ConclusionsIndulgent feeding should be addressed in future family-focused childhood obesity initiatives focused on young children and their parents.
Exploring influences on evaluation practice: a case study of a national physical activity programme
Authors: Fynn Judith F. , Hardeman Wendy , Milton Karen , Jones Andy 
Published: February 2021

AbstractBackgroundInterventions to improve physical activity behaviour are a core part of public health policy and practice. It is essential that we evaluate these interventions and use the evidence to inform decisions to improve population health. Evaluation of ‘real-world’ interventions provide an opportunity to generate practice-relevant evidence, however these interventions are difficult to evaluate. Various guidelines have been developed to facilitate evaluation, but evidence about their effectiveness in practice is limited. To explore influences on evaluation practice in an applied context, we conducted a case study of Sport England’s ‘Get Healthy Get Active’ (GHGA) programme. This was a national programme that funded 33 projects that were delivered and evaluated across England. The programme was chosen as it was designed to generate evidence on the role of sport in increasing physical activity and improving health. The study aimed to explore and appraise whether strategies intended to facilitate project evaluation, including funder requirements to use a standardised evaluation framework and specific data collection methods, were effective in generating evidence that enabled the programme to meet its aims.MethodsWe applied a collective case study design involving 35 semi-structured interviews, and documentary analysis of multiple sources of evidence from 23 physical activity projects funded by GHGA. We applied thematic and framework analysis. We developed a logic model and mapped actual outcomes against intended outcomes. A narrative synthesis is provided. We discuss implications for the effective commissioning and evaluation of public health interventions.ResultsWe identified five main themes of influences on evaluation practices that can act as barriers and facilitators to good practice: programme and project design; evaluation design; partnerships; resources; and organisational structures and systems. These influences are context-specific and operate through a complex set of interactions.ConclusionDeveloping a better understanding of how influences on evaluation practice can act as facilitators or barriers is vital to help close current gaps in the evidence-based practice cycle. Critically, organisational structures and systems are needed to facilitate collaborative decision making; integration of projects and evaluation across partners organisations; transfer of knowldege and insights between stakeholders; and more rapid feedback and dissemination.
A theoretical model of health management using data-driven decision-making: the future of precision medicine and health

Published: February 2021

AbstractBackgroundThe burden of chronic and societal diseases is affected by many risk factors that can change over time. The minimalisation of disease-associated risk factors may contribute to long-term health. Therefore, new data-driven health management should be used in clinical decision-making in order to minimise future individual risks of disease and adverse health effects.MethodsWe aimed to develop a health trajectories (HT) management methodology based on electronic health records (EHR) and analysing overlapping groups of patients who share a similar risk of developing a particular disease or experiencing specific adverse health effects. Formal concept analysis (FCA) was applied to identify and visualise overlapping patient groups, as well as for decision-making. To demonstrate its capabilities, the theoretical model presented uses genuine data from a local total knee arthroplasty (TKA) register (a total of 1885 patients) and shows the influence of step by step changes in five lifestyle factors (BMI, smoking, activity, sports and long-distance walking) on the risk of early reoperation after TKA.ResultsThe theoretical model of HT management demonstrates the potential of using EHR data to make data-driven recommendations to support both patients’ and physicians’ decision-making. The model example developed from the TKA register acts as a clinical decision-making tool, built to show surgeons and patients the likelihood of early reoperation after TKA and how the likelihood changes when factors are modified. The presented data-driven tool suits an individualised approach to health management because it quantifies the impact of various combinations of factors on the early reoperation rate after TKA and shows alternative combinations of factors that may change the reoperation risk.ConclusionThis theoretical model introduces future HT management as an understandable way of conceiving patients’ futures with a view to positively (or negatively) changing their behaviour. The model’s ability to influence beneficial health care decision-making to improve patient outcomes should be proved using various real-world data from EHR datasets.
Exercise rescues mitochondrial coupling in aged skeletal muscle: a comparison of different modalities in preventing sarcopenia
Authors: Harper Colin , Gopalan Venkatesh , Goh Jorming 
Published: February 2021

AbstractSkeletal muscle aging is associated with a decline in motor function and loss of muscle mass- a condition known as sarcopenia. The underlying mechanisms that drive this pathology are associated with a failure in energy generation in skeletal muscle, either from age-related decline in mitochondrial function, or from disuse. To an extent, lifelong exercise is efficacious in preserving the energetic properties of skeletal muscle and thus may delay the onset of sarcopenia. This review discusses the cellular and molecular changes in skeletal muscle mitochondria during the aging process and how different exercise modalities work to reverse these changes. A key factor that will be described is the efficiency of mitochondrial coupling—ATP production relative to O2 uptake in myocytes and how that efficiency is a main driver for age-associated decline in skeletal muscle function. With that, we postulate the most effective exercise modality and protocol for reversing the molecular hallmarks of skeletal muscle aging and staving off sarcopenia. Two other concepts pertinent to mitochondrial efficiency in exercise-trained skeletal muscle will be integrated in this review, including- mitophagy, the removal of dysfunctional mitochondrial via autophagy, as well as the implications of muscle fiber type changes with sarcopenia on mitochondrial function.

Abstract
Background
Intracerebral hemorrhage (ICH) can induce excessive accumulation of reactive oxygen species (ROS) that may subsequently cause severe white matter injury. The process of oligodendrocyte progenitor cell (OPC) differentiation is orchestrated by microglia and astrocytes, and ROS also drives the activation of microglia and astrocytes. In light of the potent ROS scavenging capacity of ceria nanoparticles (CeNP), we aimed to investigate whether treatment with CeNP ameliorates white matter injury by modulating ROS-induced microglial polarization and astrocyte alteration.

Methods
ICH was induced in vivo by collagenase VII injection. Mice were administered with PLX3397 for depleting microglia. Primary microglia and astrocytes were used for in vitro experiments. Transmission electron microscopy analysis and immunostaining were performed to verify the positive effects of CeNP in remyelination and OPC differentiation. Flow cytometry, real-time polymerase chain reaction, immunofluorescence and western blotting were used to detect microglia polarization, astrocyte alteration, and the underlying molecular mechanisms.

Results
CeNP treatment strongly inhibited ROS-induced NF-κB p65 translocation in both microglia and astrocytes, and significantly decreased the expression of M1 microglia and A1 astrocyte. Furthermore, we found that CeNP treatment promoted remyelination and OPC differentiation after ICH, and such effects were alleviated after microglial depletion. Interestingly, we also found that the number of mature oligodendrocytes was moderately increased in ICH + CeNP + PLX3397-treated mice compared to the ICH + vehicle + PLX3397 group. Therefore, astrocytes might participate in the pathophysiological process. The subsequent phagocytosis assay indicated that A1 astrocyte highly expressed C3, which could bind with microglia C3aR and hinder microglial engulfment of myelin debris. This result further replenished the feedback mechanism from astrocytes to microglia.

Conclusion
The present study reveals a new mechanism in white matter injury after ICH: ICH induces M1 microglia and A1 astrocyte through ROS-induced NF-κB p65 translocation that hinders OPC maturation. Subsequently, A1 astrocytes inhibit microglial phagocytosis of myelin debris via an astrocytic C3-microglial C3aR axis. Polyethylene glycol-CeNP treatment inhibits this pathological process and ultimately promotes remyelination. Such findings enlighten us that astrocytes and microglia should be regarded as a functional unit in future works.

Published: February 2021

AbstractInterventions to reduce tremor in essential tremor (ET) and Parkinson’s disease (PD) clinical populations often utilize pharmacological or surgical therapies. However, there can be significant side effects, decline in effectiveness over time, or clinical contraindications for these interventions. Therefore, alternative approaches must be considered and developed. Some non-pharmacological strategies include assistive devices, orthoses and mechanical loading of the tremorgenic limb, while others propose peripheral electrical stimulation. Specifically, peripheral electrical stimulation encompasses strategies that activate motor and sensory pathways to evoke muscle contractions and impact sensorimotor function. Numerous studies report the efficacy of peripheral electrical stimulation to alter tremor generation, thereby opening new perspectives for both short- and long-term tremor reduction. Therefore, it is timely to explore this promising modality in a comprehensive review. In this review, we analyzed 27 studies that reported the use of peripheral electrical stimulation to reduce tremor and discuss various considerations regarding peripheral electrical stimulation: the stimulation strategies and parameters, electrodes, experimental designs, results, and mechanisms hypothesized to reduce tremor. From our review, we identified a high degree of disparity across studies with regard to stimulation patterns, experimental designs and methods of assessing tremor. Having standardized experimental methodology is a critical step in the field and is needed in order to accurately compare results across studies. With this review, we explore peripheral electrical stimulation as an intervention for tremor reduction, identify the limitations and benefits of the current state-of-the-art studies, and provide ideas to guide the development of novel approaches based on the neural circuitries and mechanical properties implied in tremor generation.
