The Knowledge Translation of Early Cerebral Palsy (KiTE CP) Study: Implementing Screening Among a High-Risk Prospective Cohort of Australian Infants.

OBJECTIVE: To describe the implementation of the international guidelines for the early diagnosis of cerebral palsy (CP) and engagement in the screening process in an Australian cohort of infants with neonatal risk factors for CP. STUDY DESIGN: Prospective cohort study of infants with neonatal risk factors recruited at <6 months corrected age from 11 sites in the states of Victoria, New South Wales, and Queensland, Australia. First, we implemented a multimodal knowledge translation strategy including barrier identification, technology integration, and special interest groups. Screening was implemented as follows: infants with clinical indications for neuroimaging underwent magnetic resonance imaging and/or cranial ultrasound. The Prechtl General Movements Assessment (GMA) was recorded clinically or using an app (Baby Moves). Infants with absent or abnormal fidgety movements on GMA videos were offered further assessment using the Hammersmith Infant Neurological Examination (HINE). Infants with atypical findings on 2/3 assessments met criteria for high risk of CP. RESULTS: Of the 597 infants (56% male) recruited, 95% (n = 565) received neuroimaging, 90% (n = 537) had scorable GMA videos (2% unscorable/8% no video), and 25% (n = 149) HINE. Overall, 19% of the cohort (n = 114/597) met criteria for high risk of CP, 57% (340/597) had at least 2 normal assessments (of neuroimaging, GMA or HINE), and 24% (n = 143/597) had insufficient assessments. CONCLUSIONS: Early CP screening was implemented across participating sites using a multimodal knowledge translation strategy. Although the COVID-19 pandemic affected recruitment rates, there was high engagement in the screening process. Reasons for engagement in early screening from parents and clinicians warrant further contextualization and investigation.

Development and Evaluation of a Framework for Authentic Online Co-Design: Partnership-Focussed Principles-Driven Online Co-Design.

INTRODUCTION: Co-design in health research involves patient and public involvement and engagement (PPIE) in intervention or service design. Traditionally, co-design is undertaken in-person; however, exploring online delivery is warranted. PPIE in co-design must be considered carefully, and assumptions that in-person approaches will transition automatically to an online environment should be avoided. Currently, there are a lack of evidence-informed approaches to facilitating co-design online. This study aimed to develop and evaluate a framework for authentically adapting health research co-design into an online environment. MATERIALS AND METHODS: The initial framework was developed through a literature review, synthesis of in-person co-design principles, and alignment of online strategies. The framework was then applied to a co-design project with 10 participants across relevant PPIE groups (end-users [n = 4], clinicians [n = 2], coaches [n = 2] and clinician-researchers [n = 2]). Participants' experiences of the online co-design process were evaluated via a mixed-methods design using surveys and semi-structured interviews. Evaluation data were analysed using descriptive statistics and reflexive thematic analysis to inform a revised framework. RESULTS: The developed framework, Partnership-focussed Principles-driven Online co-Design (P-POD) was used to design eight 90 min online co-design workshops. Evaluation data involved 46 survey responses, and eight participants were interviewed on project completion. Survey data indicated that the process was satisfying, engaging and adhered to the P-POD framework. Themes derived from interview data describe a respectful and collaborative online culture, valuing of diverse perspectives and space for healthy debate, how power was perceived as being shared but not equal and multiple definitions of success within and beyond the process. A final, refined P-POD framework is presented. CONCLUSION: With evaluation of the initial P-POD framework showing evidence of adherence to co-design principles, positive participant experiences and goal achievement for both the project and the participants, the refined P-POD framework may be used and evaluated within future intervention or service design. PATIENT OR PUBLIC CONTRIBUTION: This study involved the participants (end-users, clinicians and service providers) in the co-design process described, interpretation of the results through member-checking interview responses, assisting in development of the final framework and as co-authors for this manuscript.

Impact of current Australian paid parental leave on families of preterm and sick infants.

AIM: Parents of preterm or sick infants are at increased risk of mental health problems. The financial stress associated with an infant's prolonged hospital stay can have an additional negative effect on families' wellbeing and child development. This study explores parent use of Australian paid parental leave (PPL) and the financial impact of having an infant requiring neonatal care. METHODS: Retrospective, cross-sectional, online survey study conducted from November 2020 to February 2021. Participants were parents of babies born from 1 January 2013, admitted to a neonatal intensive care unit or special care nursery in Australia. The survey explored use of Australian Government and private sector PPL, and financial stress. Parent-reported anxiety and depression were measured using the EuroQol Group 5D-5L Anxiety and Stress Subscale. RESULTS: Two hundred and thirty-one parents responded of which 93% had a preterm infant. Seventy-three percent of infants were hospitalised for more than 1 month, and 34% were readmitted to hospital within the first year following discharge home. Eighty-three percent of parents reported moderate, severe or extreme levels of anxiety or depression. Seventy-six percent reported that having a child in hospital had a moderate-very large financial impact on their family. Parents identified main costs to be travel, food, inability to work and direct medical costs. CONCLUSIONS: Having an infant born preterm or sick has significant emotional and financial implications for families. The current Australian Government PPL scheme does not adequately support parents of preterm or sick infants, and a change is urgently needed to improve outcomes for this vulnerable population.

Missing out on precious time: Extending paid parental leave for parents of babies admitted to neonatal intensive or special care units for prolonged periods.

In Australia, approximately 18% of newborn babies are admitted to a neonatal intensive or special care nursery. While most babies admitted to a neonatal intensive or special care nursery are discharged home within a few weeks, around 6% of babies spend more than 2 weeks in hospital. For the parents of these babies, much of their leave entitlements (Australian Government Paid Parental Leave Scheme is up to18 weeks for the primary care giver and up to 2 weeks for partners) are used before their baby comes home from hospital. The time babies and parents spend together in the early developmental period, during the hospitalisation and when the baby is discharged home, is crucial for optimal child development and bonding. Yet care givers who have a baby admitted to neonatal intensive or special care for extended periods are not currently entitled to any extra parental leave payments in Australia. We recommend the Australian Paid Parental Leave Act is changed to allow primary carers access to 1 week of extra parental leave pay for every week in hospital (for babies admitted to hospital for more than 2 weeks), up to a maximum of 14 weeks. For fathers and partners of these babies, we recommend an additional 2 weeks of extra Dad and Partner Pay. The net cost, taking into account likely productivity benefits, would be less than 1.5% of the current cost of the scheme and would improve health and socio-economic outcomes for the baby, family and society.

Barriers and facilitators to community participation for preschool age children born very preterm: a prospective cohort study.

AIM: We compared preschool age children born very preterm with term-born controls to: (1) understand the association between very preterm birth and community participation, (2) determine if motor impairment or social risk affect participation differently between groups, and (3) understand environmental barriers and supports to participation for parents. METHOD: Forty-eight children born very preterm (<30wks' gestation; 22 males, 26 females) and 96 controls (47 males, 49 females) were assessed at 4 to 5 years' corrected age for community participation using the Young Children's Participation and Environment Measure. Motor skills were assessed using the Movement Assessment Battery for Children, Second Edition and the Little Developmental Coordination Disorder Questionnaire. RESULTS: Children born very preterm participated less frequently than term-born children (difference in means=-0.28, 95% confidence interval [CI] -0.54 to -0.03, p=0.029). Social risk was associated with lower frequency (interaction p<0.001) and involvement (interaction p=0.05) in community activities for children in the very preterm group only. Parents of children born very preterm perceived more barriers (odds ratio=4.32, 95% CI 1.46-12.77, p=0.008) and environmental factors to be less supportive of participation than parents of controls (difference in medians=-6.21, 95% CI -11.42 to -1.00, p=0.02). INTERPRETATION: Children born very preterm may benefit from ongoing support to promote participation, especially in families of higher social risk.

Movement-based interventions for preschool-age children with, or at risk of, motor impairment: a systematic review.

AIM: To explore the efficacy of movement-based interventions to improve motor skills in preschool-age children with, or at risk of, motor impairment, including those with a diagnosis of cerebral palsy, autism spectrum disorder, and developmental coordination disorder. METHOD: Relevant electronic databases were searched for randomized or quasi-randomized controlled trials. Outcomes were classified using domains of the International Classification of Functioning, Disability and Health: Children & Youth version. Quality was assessed using the Physiotherapy Evidence Database scale. Risk of bias was assessed using the Cochrane Risk of Bias tool. Effect sizes were calculated using Cohen's d. RESULTS: Seventeen articles exploring a heterogeneity of intervention types, population groups, and outcome measures met the inclusion criteria. Movement-based interventions did not significantly improve outcomes in either the body structure and function or activity domains in most studies. No studies used a participation outcome measure. INTERPRETATION: There is a paucity of evidence exploring movement-based interventions in the preschool-age group. Although movement-based interventions showed potential for improving body structure and function and activity outcomes for children with motor impairment, results were mostly not significant. Small sample sizes, variable study quality, and risk of bias limit confidence in the results. WHAT THIS PAPER ADDS: The evidence is inconclusive to support movement-based interventions in this group. No studies used outcome measures assessing participation. Variability in intervention type and study quality limit confidence in results.

Accuracy and acceptability of survivorship care plans: results of a pilot study.

Survivorship treatment summaries and care plans are increasingly incorporated into cancer care but there are limited data on their accuracy and acceptability. We have evaluated written care plans developed as part of a once-off, nurse-led survivorship consultations across four medical oncology clinics in South Australia as part of a state-wide pilot. While the accuracy of treatment summaries was high, level of detail in care plans was moderate to low, as was survivors' perception of plans' utility.

Do stroke survivors agree with their clinicians on the extent of their post-stroke activity limitation and participation restriction?

This study aimed to examine discrepancies in the reporting of post-stroke functioning between stroke survivors and their clinicians across various disability domains and across current and predicted functioning. Fifty sub-acute stroke survivors (Age M = 70.30 SD = 15.80, 56% female) and their occupational therapist independently completed three measures assessing activity limitations (cognitive, physical, instrumental) and participation restrictions. Assessments were made of current functioning and predicted functioning at three months' post-discharge. Compared to physical functioning, appraisal discrepancies were more pronounced for cognitive functioning, instrumental activity limitation, and participation restriction. Discrepancies were more pronounced for current, as opposed to predicted, cognitive functioning (Z = -4.21, p < .001) and instrumental activity limitation (Z = -4.00, p < .001). Conversely, discrepancies in participation restriction were greatest for predicted functioning (Z = -4.03, p < .001). Follow-up (n = 39) showed that, compared to survivors' predictions, clinicians' predictions were more closely aligned with actual stroke survivor functioning at three months' post-discharge (as rated by a close other). These findings suggest appraisal discrepancy varies across disability domains and time reference points, with cognitive and complex functional activities being particularly discrepant between stroke survivors and clinicians. Furthermore, clinicians may hold more realistic expectations of short-term functional recovery.

Structure-function analyses generate novel specificities to assemble the components of multienzyme bacterial cellulosome complexes.

The cellulosome is a remarkably intricate multienzyme nanomachine produced by anaerobic bacteria to degrade plant cell wall polysaccharides. Cellulosome assembly is mediated through binding of enzyme-borne dockerin modules to cohesin modules of the primary scaffoldin subunit. The anaerobic bacterium Acetivibrio cellulolyticus produces a highly intricate cellulosome comprising an adaptor scaffoldin, ScaB, whose cohesins interact with the dockerin of the primary scaffoldin (ScaA) that integrates the cellulosomal enzymes. The ScaB dockerin selectively binds to cohesin modules in ScaC that anchors the cellulosome onto the cell surface. Correct cellulosome assembly requires distinct specificities displayed by structurally related type-I cohesin-dockerin pairs that mediate ScaC-ScaB and ScaA-enzyme assemblies. To explore the mechanism by which these two critical protein interactions display their required specificities, we determined the crystal structure of the dockerin of a cellulosomal enzyme in complex with a ScaA cohesin. The data revealed that the enzyme-borne dockerin binds to the ScaA cohesin in two orientations, indicating two identical cohesin-binding sites. Combined mutagenesis experiments served to identify amino acid residues that modulate type-I cohesin-dockerin specificity in A. cellulolyticus Rational design was used to test the hypothesis that the ligand-binding surfaces of ScaA- and ScaB-associated dockerins mediate cohesin recognition, independent of the structural scaffold. Novel specificities could thus be engineered into one, but not both, of the ligand-binding sites of ScaB, whereas attempts at manipulating the specificity of the enzyme-associated dockerin were unsuccessful. These data indicate that dockerin specificity requires critical interplay between the ligand-binding surface and the structural scaffold of these modules.

Centrality of spirituality/religion in the culture of palliative care service in Indonesia: An ethnographic study.

Experiencing life-threatening illness could impact on an individual's spirituality or religious beliefs. In this paper, we report on a study which explored cultural elements that influence the provision of palliative care for people with cancer. A contemporary ethnographic approach was adopted. Observations and interviews were undertaken over 3 months with 48 participants, including palliative care staff, patients, and their families. An ethnographic data analysis framework was adopted to assist in the analysis of data at item, pattern, and structural levels. Religion was identified as central to everyday life, with all participants reporting being affiliated to particular religions and performing their religious practices in their daily lives. Patients' relatives acknowledged and addressed patients' needs for these practices. Staff provided spiritual care for the patients and their relatives in the form of religious discussion and conducting prayers together. An understanding that religious and spiritual practices are integral cultural elements and of fundamental importance to the holistic health of their patients is necessary if health-care professionals are to support patients and their families in end-of-life care.

Modelling foetal exposure to maternal smoking using hepatoblasts from pluripotent stem cells.

The liver is a dynamic organ which is both multifunctional and highly regenerative. A major role of the liver is to process both endo and xenobiotics. Cigarettes are an example of a legal and widely used drug which can cause major health problems for adults and constitute a particular risk to the foetus, if the mother smokes during pregnancy. Cigarette smoke contains a complex mixture of thousands of different xenobiotics, including nicotine and polycyclic aromatic hydrocarbons. These affect foetal development in a sex-specific manner, inducing sex-dependant molecular responses in different organs. To date, the effect of maternal smoking on the foetal liver has been studied in vitro using cell lines, primary tissue and animal models. While these models have proven to be useful, poor cell phenotype, tissue scarcity, batch-to-batch variation and species differences have led to difficulties in data extrapolation toward human development. Therefore, in this study we have employed hepatoblasts, derived from pluripotent stem cells, to model the effects of xenobiotics from cigarette smoke on human hepatocyte development. Highly pure hepatocyte populations (>90%) were produced in vitro and exposed to factors present in cigarette smoke. Analysis of ATP levels revealed that, independent of the sex, the majority of smoking derivatives tested individually did not deplete ATP levels below 50%. However, following exposure to a cocktail of smoking derivatives, ATP production fell below 50% in a sex-dependent manner. This was paralleled by a loss metabolic activity and secretory ability in both female and male hepatocytes. Interestingly, cell depletion was less pronounced in female hepatocytes, whereas caspase activation was ~twofold greater, indicating sex differences in cell death upon exposure to the smoking derivatives tested.

Erratum to: Modelling foetal exposure to maternal smoking using hepatoblasts from pluripotent stem cells.

During manuscript proofing, the following sentence was not deleted in the section "Results" at the end of the paragraph: "Both male and female hepatocytes responded in a similar fashion to cotinine, whereas male hepatocyte function was more sensitive to chrysene, fluorene and naphthalene than female hepatocytes".

Cell-surface Attachment of Bacterial Multienzyme Complexes Involves Highly Dynamic Protein-Protein Anchors.

Protein-protein interactions play a pivotal role in the assembly of the cellulosome, one of nature's most intricate nanomachines dedicated to the depolymerization of complex carbohydrates. The integration of cellulosomal components usually occurs through the binding of type I dockerin modules located at the C terminus of the enzymes to cohesin modules located in the primary scaffoldin subunit. Cellulosomes are typically recruited to the cell surface via type II cohesin-dockerin interactions established between primary and cell-surface anchoring scaffoldin subunits. In contrast with type II interactions, type I dockerins usually display a dual binding mode that may allow increased conformational flexibility during cellulosome assembly. Acetivibrio cellulolyticus produces a highly complex cellulosome comprising an unusual adaptor scaffoldin, ScaB, which mediates the interaction between the primary scaffoldin, ScaA, through type II cohesin-dockerin interactions and the anchoring scaffoldin, ScaC, via type I cohesin-dockerin interactions. Here, we report the crystal structure of the type I ScaB dockerin in complex with a type I ScaC cohesin in two distinct orientations. The data show that the ScaB dockerin displays structural symmetry, reflected by the presence of two essentially identical binding surfaces. The complex interface is more extensive than those observed in other type I complexes, which results in an ultra-high affinity interaction (Ka ∼10(12) M). A subset of ScaB dockerin residues was also identified as modulating the specificity of type I cohesin-dockerin interactions in A. cellulolyticus. This report reveals that recruitment of cellulosomes onto the cell surface may involve dockerins presenting a dual binding mode to incorporate additional flexibility into the quaternary structure of highly populated multienzyme complexes.

Combined Crystal Structure of a Type I Cohesin: MUTATION AND AFFINITY BINDING STUDIES REVEAL STRUCTURAL DETERMINANTS OF COHESIN-DOCKERIN SPECIFICITIES.

Cohesin-dockerin interactions orchestrate the assembly of one of nature's most elaborate multienzyme complexes, the cellulosome. Cellulosomes are produced exclusively by anaerobic microbes and mediate highly efficient hydrolysis of plant structural polysaccharides, such as cellulose and hemicellulose. In the canonical model of cellulosome assembly, type I dockerin modules of the enzymes bind to reiterated type I cohesin modules of a primary scaffoldin. Each type I dockerin contains two highly conserved cohesin-binding sites, which confer quaternary flexibility to the multienzyme complex. The scaffoldin also bears a type II dockerin that anchors the entire complex to the cell surface by binding type II cohesins of anchoring scaffoldins. In Bacteroides cellulosolvens, however, the organization of the cohesin-dockerin types is reversed, whereby type II cohesin-dockerin pairs integrate the enzymes into the primary scaffoldin, and type I modules mediate cellulosome attachment to an anchoring scaffoldin. Here, we report the crystal structure of a type I cohesin from B. cellulosolvens anchoring scaffoldin ScaB to 1.84-Å resolution. The structure resembles other type I cohesins, and the putative dockerin-binding site, centered at ß-strands 3, 5, and 6, is likely to be conserved in other B. cellulosolvens type I cohesins. Combined computational modeling, mutagenesis, and affinity-based binding studies revealed similar hydrogen-bonding networks between putative Ser/Asp recognition residues in the dockerin at positions 11/12 and 45/46, suggesting that a dual-binding mode is not exclusive to the integration of enzymes into primary cellulosomes but can also characterize polycellulosome assembly and cell-surface attachment. This general approach may provide valuable structural information of the cohesin-dockerin interface, in lieu of a definitive crystal structure.

Current status of palliative care services in Indonesia: a literature review.

AIM: To review healthcare literature in relation to the provision of palliative care in Indonesia and to identify factors that may impact on palliative care development. BACKGROUND: People living with life-limiting illness benefit from access to palliative care services to optimize quality of life. Palliative care services are being expanded in developing countries but in Indonesia such services are in their infancy with many patients with life-limiting illnesses having access to appropriate health care compromised. METHODS: Relevant healthcare databases including CINAHL, PubMed, Science Direct and Scopus were searched using the combinations of search terms: palliative care, terminal care, end-of-life care, Indonesia and nursing. A search of grey literature including Internet sites was also carried out. RESULTS: Nine articles were included in the review. Facilitating factors supporting the provision of palliative care included: a culture of strong familial support, government policy support, volunteering and support from regional organizations. Identified barriers to palliative care provision were a limited understanding of palliative care among healthcare professionals, the challenging geography of Indonesia and limited access to opioid medications. CONCLUSIONS: There are facilitators and barriers that currently impact on the development of palliative care in Indonesia. Strategies that can be implemented to improve palliative care include training of nurses and doctors in the primary care sector, integrating palliative care in undergraduate medical and nursing curriculum and educating family and community about basic care. Nurses and doctors who work in primary care can potentially play a role in supporting and educating family members providing direct care to patients with palliative needs.

Small angle X-ray scattering analysis of Clostridium thermocellum cellulosome N-terminal complexes reveals a highly dynamic structure.

Clostridium thermocellum produces the prototypical cellulosome, a large multienzyme complex that efficiently hydrolyzes plant cell wall polysaccharides into fermentable sugars. This ability has garnered great interest in its potential application in biofuel production. The core non-catalytic scaffoldin subunit, CipA, bears nine type I cohesin modules that interact with the type I dockerin modules of secreted hydrolytic enzymes and promotes catalytic synergy. Because the large size and flexibility of the cellulosome preclude structural determination by traditional means, the structural basis of this synergy remains unclear. Small angle x-ray scattering has been successfully applied to the study of flexible proteins. Here, we used small angle x-ray scattering to determine the solution structure and to analyze the conformational flexibility of two overlapping N-terminal cellulosomal scaffoldin fragments comprising two type I cohesin modules and the cellulose-specific carbohydrate-binding module from CipA in complex with Cel8A cellulases. The pair distribution functions, ab initio envelopes, and rigid body models generated for these two complexes reveal extended structures. These two N-terminal cellulosomal fragments are highly dynamic and display no preference for extended or compact conformations. Overall, our work reveals structural and dynamic features of the N terminus of the CipA scaffoldin that may aid in cellulosome substrate recognition and binding.

Assessing cognitive communication skills for returning to work following acquired brain injury: a systematic scoping review.

PURPOSE: Cognitive communication impairments resulting from acquired brain injury (ABI) impact a person's ability to return to and maintain employment. This study reviews the assessment of cognitive communication skills for return to work after injury. MATERIALS AND METHODS: A scoping review was conducted. Key search terms included brain injury, cognitive communication, work and their synonyms. Studies were included if participants had an ABI diagnosis, were at least 16 years old, mentioned vocational rehabilitation or return to work, and cognition or cognitive communication. RESULTS: A total of 692 studies were identified through database searches with an additional 18 articles found through handsearching. Fourteen articles were included in the final review. Measures, most included in studies target discrete skills when aligned to the Model of Cognitive Communication Competence. The Individual and Contextual Domains of the model were not well represented and there were limited measures able to capture self or other reported data. CONCLUSIONS: Assessment of cognitive communication skills for returning to work following ABI requires an individualised and contextualised approach. This study highlights a gap between key clinical models and measures reported in the current literature. Further research into clinical practice is required.

Research into resources to help clinicians capture information related to the individual, their role and work environment are needed to support contextualised assessment for return to work.The multifactorial nature of communication should be considered when assessing cognitive communication for return to work. Models such as the Model of Cognitive Communication Competence are available.Measures such as the Functional Assessment of Verbal Reasoning and Executive Strategies and the La Trobe Communication Questionnaire can be considered.

When stroke survivors' self-ratings are inconsistent with the ratings of others: a cohort study examining biopsychosocial factors associated with impaired self-awareness of functional abilities.

Background Stroke survivors' self-ratings of functional abilities are often inconsistent with ratings assigned by others (e.g. clinicians), a phenomenon referred to as 'impaired self-awareness' (ISA). There is limited knowledge of the biopsychosocial contributors and consequences of post-stroke ISA measured across the rehabilitation journey. This multi-site cohort study explored biopsychosocial correlates of ISA during subacute rehabilitation (inpatient) and at 4 months post-discharge (community-dwelling). Methods Forty-five subacute stroke survivors participated (Age M (s.d.) = 71.5 (15.6), 56% female), and 38 were successfully followed-up. Self-assessments were compared to those of an independent rater (occupational therapist, close other) to calculate ISA at both time points. Survivors and raters completed additional cognitive, psychological and functional measures. Results Multivariate regression (multiple outcomes) identified associations between ISA during inpatient admission and poorer outcomes at follow-up, including poorer functional cognition, participation restriction, caregiver burden, and close other depression and anxiety. Regression models applied cross-sectionally, including one intended for correlated predictors, indicated associations between ISA during inpatient admission and younger age, male sex, poorer functional cognition, poorer rehabilitation engagement and less frequent use of non-productive coping (adjusted R 2 = 0.60). ISA at community follow-up was associated with poorer functional cognition and close other anxiety (adjusted R 2 = 0.66). Conclusions Associations between ISA and poorer outcomes across the rehabilitation journey highlight the clinical importance of ISA and the value of assessment and management approaches that consider the potential influence of numerous biological and psychosocial factors on ISA. Future studies should use larger sample sizes to confirm these results and determine the causal mechanisms of these relationships.
