"I have to fight for them to investigate things": a qualitative exploration of physical and mental healthcare for women diagnosed with mental illness.

Introduction: Women play a significant role in the management of their own healthcare and that of others, however women diagnosed with mental illness and physical health concerns experience significant health inequalities as compared to people living without mental health concerns. Methods: In this paper, we reflect on the experiences of 20 cis women diagnosed with mental and physical health concerns who agreed to be a part of this research. This qualitative study is part of the larger Healthtalk Australia research project which was not gender specific. Female participants shared many experiences of mental and physical healthcare in interviews with researchers that pointed to the need for a gendered approach to addressing health inequalities. Consequently, we iteratively consolidated transcripts of interviews with participants into thematic categories facilitated by NVIVO 12. Results: We identified two broad themes and a set of subthemes: in the doctor's office - experience of labelling; negotiating medications; and interactions with physical and mental health, and outside the doctor's office - responses to trauma, financial concerns, and reliance on participant's internal resources to get healthcare needs met. Discussion: We conclude that participants in this study undertook significant work to manage their own healthcare needs, despite being challenged by clinicians and systems that failed to see them as whole people with expertise regarding their own health.

Effectiveness of Deep Brain Stimulation in Improving Balance in Parkinson's Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: Balance dysfunction is a debilitating feature of advanced Parkinson's disease (PD), potentially improved by deep brain stimulation (DBS). This systematic review and meta-analysis pooled evidence from randomized controlled trials (RCTs) on DBS effectiveness in improving balance in PD. METHODS: A systematic search was conducted to identify eligible RCTs investigating the effectiveness of DBS on improving balance in people with PD. Meta-analysis was performed using random effects models and reported as mean difference and 95% confidence intervals. Risk of bias was assessed using Cochrane's ROB-2 tool. RESULTS: Seventeen RCTs were eligible (n = 333), utilizing a range of stimulation sites, parameters, reporting tools for balance outcomes, and control/comparator groups, making the identification of clear trends and recommendations difficult. Eleven studies were deemed as having some risk of bias, 4 having low risk of bias and 2 having high risk of bias. One small meta-analysis was conducted and found no significant difference in balance outcomes. Most studies reported no significant improvement in Timed Up-and-Go scores, Berg Balance Scale scores, frequency of falls, and balance-related items of the Movement Disorder Society's Unified Parkinson's Disease Rating Scales. Some studies reported improvements in the Tinetti balance test, posturography readings, and reduction in falls though these were not supported by other studies due to a lack of reporting on these items or conflicting findings. CONCLUSIONS: Current research suggests that DBS results in no significant improvement in balance dysfunction for people with PD, though such assertions require larger RCTs with clear reporting methods using validated reporting tools.

Separating the rash from the chaff: novel clinical decision support deployed during the mpox outbreak.

A clinical decision support system, EvalMpox, was developed to apply person under investigation (PUI) criteria for patients presenting with rash and to recommend testing for PUIs. Of 668 patients evaluated, an EvalMpox recommendation for testing had a positive predictive value of 35% and a negative predictive value of 99% for a positive mpox test.

Educational interventions to improve compliance with disinfection practices of noncritical portable medical equipment: A systematic review.

OBJECTIVE: To describe educational interventions that have been implemented in healthcare settings to increase the compliance of healthcare personnel (HCP) with cleaning and disinfection of noncritical portable medical equipment (PME) requiring low-level disinfection (LLD). DESIGN: Systematic review. METHODS: Studies evaluating interventions for improving LLD practices in settings with HCP, including healthcare students and trainees, were eligible for inclusion. RESULTS: In total, 1,493 abstracts were identified and 1,416 were excluded, resulting in 77 studies that underwent full text review. Among these, 68 were further excluded due to study design, setting, or intervention. Finally, 9 full-text studies were extracted; 1 study was excluded during the critical appraisal process, leaving 8 studies. Various forms of interventions were implemented in the studies, including luminescence, surveillance of contamination with feedback, visual signage, enhanced training, and improved accessibility of LLD supplies. Of the 8 included studies, 4 studies reported successes in improving LLD practices among HCP. CONCLUSIONS: The available literature was limited, indicating the need for additional research on pedagogical methods to improve LLD practices. Use of visual indicators of contamination and multifaceted interventions improved LLD practice by HCP.

Is implementing a post-lunch nap beneficial on evening performance, following two nights partial sleep restriction?

We have investigated the effects that partial-sleep-restriction (PSR0, 4-h sleep retiring at 02:30 and waking at 06:30 h for two consecutive nights) have on 07:30 and 17:00 h cognitive and submaximal weightlifting; and whether this performance improves at 17:00 h following a 13:00 h powernap (0, 30 or 60-min). Fifteen resistance-trained males participated in this study. Prior to the experimental protocol, one repetition max (1RM) bench press and back squat, normative habitual sleep and food intake were recorded. Participants were familiarised with the testing protocol, then completed three experimental conditions: (i) PSR with no nap (PSR0); (ii) PSR with a 30-min nap (PSR30) and (iii) PSR with a 60-min nap (PSR60). Conditions were separated by 7 days with trial order counterbalanced. Intra-aural temperature, Profile of Mood Scores, word-colour interference, alertness and tiredness values were measured at 07:30, 11:00, 14:00, 17:00 h on the day of exercise protocol. Following final temperature measurements at 07:30 h and 17:00 h, participants completed a 5-min active warm-up before performing three repetitions of left and right-hand grip strength, followed by three repetitions at each incremental load (40, 60 and 80% of 1RM) for bench press and back squat, with a 5-min recovery between each repetition. A linear encoder was attached perpendicular to the bar used for the exercises. Average power (AP), average velocity (AV), peak velocity (PV), displacement (D) and time-to-peak velocity (tPV) were measured (MuscleLab software) during the concentric phase of the movements. Data were analysed using general linear models with repeated measures. The main findings were that implementing a nap at 13:00 h had no effect on measures of strength (grip, bench press or back squat). There was a main effect for time of day with greatest performance at 17:00 h for measures of strength. In addition to a significant effect for "load" on the bar for bench press and back squat where AP, AV, PV, D values were greatest at 40% (P < 0.05) and decreased with increased load, whereas tPV and RPE values increased with load; despite this no interaction of "load and condition" were present. A post lunch nap of 30- and 60-minute durations improved mood state, with feelings of alertness, vigour and happiness highest at 17:00 h, in contrast to confusion, tiredness and fatigue (P < 0.05), which were greater in the morning (07:30 h). The word-colour interference test, used as an indicator of cognitive function, reported significant main effect for condition, with the highest total test score in PSR60 condition (P = 0.015). In summary, unlike strength measures the implementation of a 30 or 60-minute nap improved cognitive function when in a partially sleep restricted state, compared to no nap.

State Implementation of SNAP Waivers and Flexibilities During the COVID-19 Pandemic: Perspectives From State Agency Leaders.

OBJECTIVE: To describe state agencies' implementation of the Supplemental Nutrition Assistance Program (SNAP) during the first year of the coronavirus disease of 2019 (COVID-19) pandemic, barriers and facilitators to SNAP implementation, and recommendations to improve SNAP implementation. DESIGN: Qualitative methodology guided by Bullock's determinants of policy implementation framework using 7 semistructured, virtual focus groups in April 2021. SETTING: Twenty-six states representing all 7 US Department of Agriculture Food and Nutrition Service regions. PARTICIPANTS: Four focus groups with state-level SNAP administrators and 3 focus groups with state-level SNAP supportive services (Supplemental Nutrition Assistance Program-Education, Employment & Training, and Outreach) supervisors (n = 62). PHENOMENON OF INTEREST: Supplemental Nutrition Assistance Program implementation during the COVID-19 pandemic. ANALYSIS: Thematic analysis using a phronetic iterative approach. RESULTS: Six primary themes emerged: the policy response, technology needs, collaboration, participant communication, funding realities, and equity. Implementation challenges included the design of waivers in the early pandemic response, inadequate federal guidance and funding, outdated technology, and prepandemic regulations limiting state authority. Modernized technology systems, availability of virtual programming, partnerships, and enhanced benefits facilitated SNAP implementation. CONCLUSIONS AND IMPLICATIONS: Supplemental Nutrition Assistance Program administrators adapted their programs to deliver services virtually during the COVID-19 pandemic. These experiences highlighted the importance of certain policy determinants, such as modernized technology and streamlined application processes, to improve outcomes for SNAP participants and staff.

Implementation and prospective evaluation of the Country Heart Attack Prevention model of care to improve attendance and completion of cardiac rehabilitation for patients with cardiovascular diseases living in rural Australia: a study protocol.

INTRODUCTION: Despite extensive evidence of its benefits and recommendation by guidelines, cardiac rehabilitation (CR) remains highly underused with only 20%-50% of eligible patients participating. We aim to implement and evaluate the Country Heart Attack Prevention (CHAP) model of care to improve CR attendance and completion for rural and remote participants. METHODS AND ANALYSIS: CHAP will apply the model for large-scale knowledge translation to develop and implement a model of care to CR in rural Australia. Partnering with patients, clinicians and health service managers, we will codevelop new approaches and refine/expand existing ones to address known barriers to CR attendance. CHAP will codesign a web-based CR programme with patients expanding their choices to CR attendance. To increase referral rates, CHAP will promote endorsement of CR among clinicians and develop an electronic system that automatises referrals of in-hospital eligible patients to CR. A business model that includes reimbursement of CR delivered in primary care by Medicare will enable sustainable access to CR. To promote CR quality improvement, professional development interventions and an accreditation programme of CR services and programmes will be developed. To evaluate 12-month CR attendance/completion (primary outcome), clinical and cost-effectiveness (secondary outcomes) between patients exposed (n=1223) and not exposed (n=3669) to CHAP, we will apply a multidesign approach that encompasses a prospective cohort study, a pre-post study and a comprehensive economic evaluation. ETHICS AND DISSEMINATION: This study was approved by the Southern Adelaide Clinical Human Research Ethics Committee (HREC/20/SAC/78) and by the Department for Health and Wellbeing Human Research Ethics Committee (2021/HRE00270), which approved a waiver of informed consent. Findings and dissemination to patients and clinicians will be through a public website, online educational sessions and scientific publications. Deidentified data will be available from the corresponding author on reasonable request. TRIAL REGISTRATION NUMBER: ACTRN12621000222842.

A critical review of research into mental health consumers' perspectives on their physical health: Is there an absence of consumers in the design, conduct, analysis and reporting of this research?

We conducted a critical review, using systematic methods, of the literature examining mental health consumer perspectives on their physical and mental health in academic research published between 2005 and 2021. This review examined the inclusion, extent, type and centrality of consumer perspectives regarding their mental and physical health. The search produced 1,865 papers from which 116 met the inclusion criteria. Studies predominantly focused on consumers' individual experiences of their physical and mental health, including but not limited to their understandings and experiences of medication and associated risk factors. They also captured some social aspects of mental health consumers' physical health, including factors that impacted individual agency, stigma, and social and interpersonal factors. Structural factors affecting physical and mental health, such as accessibility of services and financial constraints, were also identified. The review revealed that in comparison to clinician perspectives, the direct representation of consumer perspectives was lacking. Similarly, while clinician and carer perspectives on structural factors were investigated, the consumer perspective in this area was missing. The review also found few genuine codesigned or coproduced research studies. To better identify and respond to the health needs as prioritized by consumers, this paper argues it is imperative that future studies prioritize codesigned and coproduced research. It is argued that a focus on "services as provided" rather than "services as received" has contributed to a lack of progress in addressing the life expectancy gap for consumers. It is recommended that journals, ethics committees and research policy organizations develop guidelines and standards to inform best practice in research on consumer perspectives and experience and to support the implementation of codesigned and/or coproduced approaches in future research. Respecting and including consumers as equal partners in the research process will lead to more meaningful insights to inform policy and practice and reduce the life expectancy gap for people living with mental health concerns.

The 'Shape-Shifter' Peptide from the Disulphide Isomerase PmScsC Shows Context-Dependent Conformational Preferences.

Multiple crystal structures of the homo-trimeric protein disulphide isomerase PmScsC reveal that the peptide which links the trimerization stalk and catalytic domain can adopt helical, ß-strand and loop conformations. This region has been called a 'shape-shifter' peptide. Characterisation of this peptide using NMR experiments and MD simulations has shown that it is essentially disordered in solution. Analysis of the PmScsC crystal structures identifies the role of intermolecular contacts, within an assembly of protein molecules, in stabilising the different linker peptide conformations. These context-dependent conformational properties may be important functionally, allowing for the binding and disulphide shuffling of a variety of protein substrates to PmScsC. They also have a relevance for our understanding of protein aggregation and misfolding showing how intermolecular quaternary interactions can lead to ß-sheet formation by a sequence that in other contexts adopts a helical structure. This 'shape-shifting' peptide region within PmScsC is reminiscent of one-to-many molecular recognition features (MoRFs) found in intrinsically disordered proteins which are able to adopt different conformations when they fold upon binding to their protein partners.

Conceptualising the social networks of vulnerable children and young people: a systematic review and narrative synthesis.

PURPOSE: The relationship between social networks and health and wellbeing is increasingly demonstrated in vulnerable adult populations. This relationship for vulnerable children and young people has not hitherto been systematically reviewed. This narrative synthesis aims to consolidate research to provide a foundational basis for future health-related social network research and interventions for children and young people. METHODS: This mixed methods systematic review synthesises research investigating whole, egocentric social networks of 32 vulnerable child groups with a mean age below 18. There were no setting, language or date restrictions. The quality was assessed using the Mixed Methods Appraisal Tool. Of 6360 search results, 49 were included for narrative synthesis. RESULTS: The majority of pertinent research originates from the USA; the most frequently investigated vulnerabilities were minority ethnic status, homelessness and the presence of special educational needs. Research aims and methodologies varied significantly between studies. Key findings included (i) vulnerable (excluding minority ethnic) children and young people have impoverished networks (ii) access to networks is a protective factor against negative outcomes (iii) social ties, primarily immediate family, provide access to personal resources and (iv) network ties are to a degree substitutable. CONCLUSIONS: Networks are associated with wellbeing and vulnerable children and young people commonly have impoverished networks, excluding cases where vulnerability classification relates to minority ethnic status. Network embeddedness is associated with positive outcomes, particularly for homeless children. Family are typically primary providers of support, but ties are substitutable when networks are restricted. Egocentric social network research is currently limited for vulnerable child populations. Further research could inform interventions that harness networks to improve health, wellbeing and functional outcomes for these child groups.

Treatment persistence and colectomy-free outcomes in patients with ulcerative colitis receiving golimumab or adalimumab: a UK experience.

OBJECTIVE: To examine real-world treatment persistence, colectomy-free survival and treatment switching patterns in UK patients with ulcerative colitis (UC) prescribed golimumab or adalimumab. DESIGN: This was a retrospective chart review study in adult patients diagnosed with UC using data from 16 National Health Service sites in the UK. Patient records were included in the study if they had initiated first or second-line adalimumab or golimumab between 1 March 2016 and 30 September 2017 (index date). Subjects were required for ≥6 months post treatment initiation. Demographics, clinical characteristics, treatment-related data and colectomy data were extracted over a follow-up period of 6-12 months. Treatment persistence rate was the primary outcome. Colectomy-free survival and treatment switching were secondary outcomes. Outcomes were compared between treatments using χ2 tests and Fisher's exact test for categorical variables. The t-tests were used for continuous variables. Time-to-event variables were evaluated using Kaplan-Meier curves and log-rank tests. RESULTS: The study included a total of 183 patients (96 (52.5%) prescribed adalimumab; 87 (47.5%) golimumab), and patients were mostly first line (79.8%). Demographic and clinical characteristics were generally similar between treatment groups. Persistence rates within 12 months were 64.6% for adalimumab and 64.4% for golimumab (p=0.681). Overall, 20.2% switched to other therapy within 1 year, with 8.2% golimumab and 12.0% adalimumab switching to another biologic. Of patients prescribed adalimumab, 14.6% had ≥1 dose change, mainly dose escalations. In the 12 months post treatment initiation, 8.2% of patients underwent colectomy, with no significant difference in colectomy-free survival by treatment, p=0.73. CONCLUSION: This study provides evidence of clinical outcomes and real-world persistence for adalimumab and golimumab in UC. The persistence rates of both therapies were above 64.0% at 12 months following treatment initiation. In addition, the 1-year colectomy-free survival was relatively similar between the two treatments.

Effect of delaying treatment of first-episode psychosis on symptoms and social outcomes: a longitudinal analysis and modelling study.

BACKGROUND: Delayed treatment for first episodes of psychosis predicts worse outcomes. We hypothesised that delaying treatment makes all symptoms more refractory, with harm worsening first quickly, then more slowly. We also hypothesised that although delay impairs treatment response, worse symptoms hasten treatment, which at presentation mitigates the detrimental effect of treatment delay on symptoms. METHODS: In this longitudinal analysis and modelling study, we included two longitudinal cohorts of patients with first-episode psychosis presenting to English early intervention services from defined catchments: NEDEN (recruiting 1003 patients aged 14-35 years from 14 services between Aug 1, 2005, and April 1, 2009) and Outlook (recruiting 399 patients aged 16-35 years from 11 services between April 1, 2006, and Feb 28, 2009). Patients were assessed at baseline, 6 months, and 12 months with the Positive and Negative Symptom Scale (PANSS), Calgary Depression Scale for Schizophrenia, Mania Rating Scale, Insight Scale, and Social and Occupational Functioning Assessment Scale. Regression was used to compare different models of the relationship between duration of untreated psychosis (DUP) and total symptoms at 6 months. Growth curve models of symptom subscales tested predictions arising from our hypotheses. FINDINGS: We included 948 patients from the NEDEN study and 332 patients from the Outlook study who completed baseline assessments and were prescribed dopamine antagonist antipsychotics. For both cohorts, the best-fitting models were logarithmic, describing a curvilinear relationship of DUP to symptom severity: longer DUP predicted reduced treatment response, but response worsened more slowly as DUP lengthened. Increasing DUP by ten times predicted reduced improvement in total symptoms (ie, PANSS total) by 7·339 (95% CI 5·762 to 8·916; p<0·0001) in NEDEN data and 3·846 (1·689 to 6·003; p=0·0005) in Outlook data. This was true of treatment response for all symptom types. Nevertheless, longer DUP was not associated with worse presentation for any symptoms except depression in NEDEN (coefficients 0·099 [95% CI 0·033 to 0·164]; p=0·0028 in NEDEN and 0·007 [-0·081 to 0·095]; p=0·88 in Outlook). INTERPRETATION: Long DUP was associated with reduced treatment response across subscales, consistent with a harmful process upstream of individual symptoms' mechanisms; response appeared to worsen quickly at first, then more slowly. These associations underscore the importance of rapid access to a comprehensive range of treatments, especially in the first weeks after psychosis onset.

Fluid reasoning predicts future mathematical performance among children and adolescents.

The aim of this longitudinal study was to determine whether fluid reasoning (FR) plays a significant role in the acquisition of mathematics skills above and beyond the effects of other cognitive and numerical abilities. Using a longitudinal cohort sequential design, we examined how FR measured at three assessment occasions, spaced approximately 1.5years apart, predicted math outcomes for a group of 69 participants between ages 6 and 21years across all three assessment occasions. We used structural equation modeling (SEM) to examine the direct and indirect relations between children's previous cognitive abilities and their future math achievement. A model including age, FR, vocabulary, and spatial skills accounted for 90% of the variance in future math achievement. In this model, FR was the only significant predictor of future math achievement; age, vocabulary, and spatial skills were not significant predictors. Thus, FR was the only predictor of future math achievement across a wide age range that spanned primary school and secondary school. These findings build on Cattell's conceptualization of FR as a scaffold for learning, showing that this domain-general ability supports the acquisition of rudimentary math skills as well as the ability to solve more complex mathematical problems.

Adolescents' use of the built environment for physical activity.

BACKGROUND: Physical activity is a health-enhancing behavior, but few adolescents achieve the recommended levels of moderate-to-vigorous physical activity. Understanding how adolescents use different built environment spaces for physical activity and activity varies by location could help in designing effective interventions to promote moderate-to-vigorous physical activity. The objective of this study was to describe the locations where adolescents engage in physical activity and compare traditional intensity-based measures with continuous activity when describing built environment use patterns among adolescents. METHODS: Eighty adolescents aged 11-14 years recruited from community health and recreation centers. Adolescents wore accelerometers (Actigraph GT3X) and global positioning system receivers (QStarz BT-Q1000XT) for two separate weeks to record their physical activity levels and locations. Accelerometer data provided a continuous measure of physical activity and intensity-based measures (sedentary time, moderate-to-vigorous physical activity). Physical activity was mapped by land-use classification (home, school, park, playground, streets & sidewalks, other) using geographic information systems and this location-based activity was assessed for both continuous and intensity-based physical activity derived from mixed-effects models which accounted for repeated measures and clustering effects within person, date, school, and town. RESULTS: Mean daily moderate-to-vigorous physical activity was 22 minutes, mean sedentary time was 134 minutes. Moderate-to-vigorous physical activity occurred in bouts lasting up to 15 minutes. Compared to being at home, being at school, on the streets and sidewalks, in parks, and playgrounds were all associated with greater odds of being in moderate-to-vigorous physical activity and achieving higher overall activity levels. Playground use was associated with the highest physical activity level (ß = 172 activity counts per minute, SE = 4, p < 0.0001) and greatest odds of being in moderate-to-vigorous physical activity (odds ratio 8.3, 95% confidence interval 4.8-14.2). CONCLUSION: Adolescents were more likely to engage in physical activity, and achieved their highest physical activity levels, when using built environments located outdoors. Novel objective methods for determining physical activity can provide insight into adolescents' spatial physical activity patterns, which could help guide physical activity interventions. Promoting zoning and health policies that encourage the design and regular use of outdoor spaces may offer another promising opportunity for increasing adolescent physical activity.

White matter maturation supports the development of reasoning ability through its influence on processing speed.

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes contribute to improved reasoning ability over development. In particular, we sought to understand whether previously reported relationships between white matter microstructure and reasoning are mediated by processing speed. To this end, we analyzed diffusion tensor imaging data as well as data from standard psychometric tests of cognitive abilities from 103 individuals between the ages of 6 and 18. We used structural equation modeling to investigate the network of relationships between brain and behavior variables. Our analyses provide support for the hypothesis that white matter maturation (as indexed either by microstructural organization or volume) supports improved processing speed, which, in turn, supports improved reasoning ability.

Will working memory training generalize to improve off-task behavior in children with attention-deficit/hyperactivity disorder?

Computerized working memory and executive function training programs designed to target specific impairments in executive functioning are becoming increasingly available, yet how well these programs generalize to improve functional deficits in disorders, such as attention-deficit/hyperactivity disorder (ADHD), beyond the training context is not well-established. The aim of this study was to examine the extent to which working memory (WM) training in children with ADHD would diminish a core dysfunctional behavior associated with the disorder, "off-task" behavior during academic task performance. The effect of computerized WM training (adaptive) was compared to a placebo condition (nonadaptive) in a randomized, double-blind, placebo-controlled design in 26 children (18 males; age, 7 to 14 years old) diagnosed with ADHD. Participants completed the training in approximately 25 sessions. The Restricted Academic Situations Task (RAST) observational system was used to assess aspects of off-task behavior during the completion of an academic task. Traditional measures of ADHD symptoms (Conners' Parent Rating Scale) and WM ability (standardized WM tests) were also collected. WM training led to significant reductions in off-task ADHD-associated behavior on the RAST system and improvement on WM tests. There were no significant differences between groups in improvement on parent rating scales. Findings lend insight into the generalizability of the effects of WM training and the relation between deficits in WM and off-task behavioral components of ADHD. These preliminary data suggest WM training may provide a mechanism for indirectly altering academic performance in children with ADHD.
