ABSTRACT

Human red blood cell acetylcholinesterase (RBC-AChE) activity is valuable for detecting potential exposure to cholinesterase inhibiting substances (CIS). A reliable population-based RBC-AChE activity reference range is critical for early and massive clinical and occupational toxicology screening. Previous published studies were often limited to small numbers of subjects, various testing methods, and crude statistical data analyses. We tested 4818 adult subjects with a well-established 17-minute modified Michel method over a 2-year period. We conducted a retrospective data analysis and systematically investigated on the influences to testing values from gender, age, age group, and their combinations and interactions. No significant difference was observed in the testing values between males (mean, medium, interquartile range = 0.76, 0.76, 0.71-0.80 ΔpH/h, respectively) and females (mean, medium, interquartile range = 0.76, 0.76, 0.71-0.81 ΔpH/hour, respectively), when gender was the only factor considered (p = 0.7238). However, with age progression, male testing values exhibited a consistent upward trend, while females did not show any clear patterns. Linear regression analysis of the data revealed that gender, age, and age group more or less affected testing values either as independent variables or with their combinations and interactions. However, more potential factors need to be included to achieve better testing value predictions. We recommend the toxicological testing community to adopt a new set of age group specific RBC-AChE activity reference ranges for males (0.68-0.80, 0.69-0.81, 0.70-0.83, 0.71-0.84, and 0.73-0.87 ΔpH/h for 18-29, 30-39, 40-49, 50-59, and ≥60 years old, respectively) while keeping the current reference range (0.63-0.89 ΔpH/hour) for females.

ABSTRACT

BACKGROUND: The ZFHX3 gene plays vital roles in embryonic development, cell proliferation, neuronal differentiation and neuronal death. This study aims to explore the relationship between ZFHX3 variants and epilepsy.

METHODS: Whole-exome sequencing was performed in a cohort of 378 patients with partial (focal) epilepsy. A Drosophila Zfh2 knockdown model was used to validate the association between ZFHX3 and epilepsy.

RESULTS: Compound heterozygous ZFHX3 variants were identified in eight unrelated cases. The burden of ZFHX3 variants was significantly higher in the case cohort, shown by multiple/specific statistical analyses. In Zfh2 knockdown flies, the incidence and duration of seizure-like behaviour were significantly greater than those in the controls. The Zfh2 knockdown flies exhibited more firing in excitatory neurons. All patients presented partial seizures. The five patients with variants in the C-terminus/N-terminus presented mild partial epilepsy. The other three patients included one who experienced frequent non-convulsive status epilepticus and two who had early spasms. These three patients had also neurodevelopmental abnormalities and were diagnosed as developmental epileptic encephalopathy (DEE), but achieved seizure-free after antiepileptic-drug treatment without adrenocorticotropic-hormone/steroids. The analyses of temporal expression (genetic dependent stages) indicated that ZFHX3 orthologous were highly expressed in the embryonic stage and decreased dramatically after birth.

CONCLUSION: ZFHX3 is a novel causative gene of childhood partial epilepsy and DEE. The patients of infantile spasms achieved seizure-free after treatment without adrenocorticotropic-hormone/steroids implies a significance of genetic diagnosis in precise treatment. The genetic dependent stage provided an insight into the underlying mechanism of the evolutional course of illness.

ABSTRACT

BACKGROUND: Use of personal sensing to predict mental health risk has sparked interest in adolescent psychiatry, offering a potential tool for targeted early intervention.

OBJECTIVES: We investigated the preferences and values of UK adolescents with regard to use of digital sensing information, including social media and internet searching behaviour. We also investigated the impact of risk information on adolescents’ self-understanding.

METHODS: Following a Design Bioethics approach, we created and disseminated a purpose-built digital game (www.tracingtomorrow.org) that immersed the player-character in a fictional scenario in which they received a risk assessment for depression Data were collected through game choices across relevant scenarios, with decision-making supported through clickable information points.

FINDINGS: The game was played by 7337 UK adolescents aged 16-18 years. Most participants were willing to personally communicate mental health risk information to their parents or best friend. The acceptability of school involvement in risk predictions based on digital traces was mixed, due mainly to privacy concerns. Most participants indicated that risk information could negatively impact their academic self-understanding. Participants overwhelmingly preferred individual face-to-face over digital options for support.

CONCLUSIONS: The potential of digital phenotyping in supporting early intervention in mental health can only be fulfilled if data are collected, communicated and actioned in ways that are trustworthy, relevant and acceptable to young people.

CLINICAL IMPLICATIONS: To minimise the risk of ethical harms in real-world applications of preventive psychiatric technologies, it is essential to investigate young people’s values and preferences as part of design and implementation processes.

ABSTRACT

INTRODUCTION: Despite better therapies and strategies, many people with rheumatoid arthritis (RA) have persistent pain, often from abnormal pain processing, now termed nociplastic pain. However, RA patients with fibromyalgia (FM), a central nociplastic pain syndrome, also have power doppler ultrasound (PDUS+) joint inflammation. To understand the complex causes of pain, we performed clinical examination and patient-reported outcome measures (PROMs) plus comprehensive PDUS evaluation not previously combined.

METHODS: In a cross-sectional study of sequential RA patients with at least moderate DAS28 erythrocyte sedimentation rate disease activity, we assessed 66/68 joints for swelling and tenderness, respectively, FM American College of Rheumatology 2010 diagnostic criteria, completed PROMs for function, quality of life and mood, alongside PDUS examination of 44 joints. Statistical analysis included logistic regression modelling and regularised (lasso) logistic regression methods.

RESULTS: From 158 patients, 72 (46%) patients met FM criteria, with significantly worse tender joint counts and PROMs, but no differences in PDUS compared with the non-FM group. Categorising patients by PDUS+ joint presence and/or FM criteria, we identified four distinct groups: 43 (27.2%) patients with -FM-PD, 43 (27.2%) with -FM+PD, 42 (26.6%) with +FM-PD and 30 (19%) with +FM+PD. Both FM+ groups had worse PROMs for fatigue, mood and pain, compared with the FM- groups. We were unable to develop algorithms to identify different groups.

CONCLUSION: The unexpected group -FM-PD group may have peripheral nociplastic pain, not commonly recognised in rheumatology. Only 46% of patients demonstrated PDUS+ inflammation. However clinical examination and PROMs did not reliably differentiate groups, emphasising PDUS remains an important tool.

ABSTRACT

The transitional period between hospital discharge and primary care follow-up is a vulnerable time for patients that can result in adverse health outcomes and preventable hospital readmissions. This is especially true for patients of safety-net hospitals (SNHs) who often struggle to secure primary care access when leaving the hospital due to social, economic and cultural barriers. In this study, we describe a resident-led postdischarge clinic that serves patients discharged from NYU Langone Hospital-Brooklyn, an urban safety-net academic hospital. In our multivariable analysis, there was no statistical difference in the readmission rate between those who completed the transitional care management and those who did not (OR 1.32 (0.75-2.36), p=0.336), but there was a statistically significant increase in primary care provider (PCP) engagement (OR 0.53 (0.45-0.62), p<0.001). Overall, this study describes a postdischarge clinic model embedded in a resident clinic in an urban SNH that is associated with increased PCP engagement, but no reduction in 30-day hospital readmissions.

ABSTRACT

BACKGROUND: The implementation of information technology (IT) in patient care is on the rise. The nursing workforce should be prepared for using such technology to support the delivery of patient-centered care. The integration of informatics into nursing practice has been progressing at a slower rate than the development of advancements and in which areas nurses use IT is still not clear.

OBJECTIVE: Our objective was to develop a new instrument to determine the usage of IT in nursing practice.

METHODS: A methodological study was conducted with factor analyses. A total of 498 registered nurses in a university hospital (n = 374) and primary care centers (n = 124) participated in the study. A questionnaire consisting demographic characteristics and an item pool with 50 statements were used to collect data. The validity and reliability of the instrument were statistically tested by computing the Keiser-Meier-Olkin (KMO) and Bartlett tests, an exploratory factor analysis, descriptive statistics, Cronbach’s α, and a confirmatory factor analysis.

RESULTS: The instrument extracted eight factors comprising 39 items that explained 55% of the variance: professional autonomy(α = 0.82), data sharing/communication(α = 0.80), data management (α = 0.79), professional development (α = 0.71), administration (α = 0.76), research (α = 0.76), informing (α = 0.68), and classification of interventions (α = 0.75). Total reliability was 0.936. KMO index and a measure of sampling adequacy were high (0.936); the Bartlett test of sphericity was significant (p < 0.005).

CONCLUSION: Study provided the evidence for the factor structure, internal consistency, reliability, and responsiveness of the 39-item “The Information Technology Scale in Nursing.” Further testing of the developed instrument with a larger number of nurses from various backgrounds and different settings is recommended.

ABSTRACT

INTRODUCTION: Self-help is an important complement to medical rehabilitation for people with chronic diseases and disabilities. It contributes to stabilising rehabilitation success and further coping with disease and disability. Rehabilitation facilities are central in informing and referring patients to self-help groups. However, sustainable cooperation between rehabilitation and self-help, as can be achieved using the concept of self-help friendliness in healthcare, is rare, as is data on the cooperation situation.

METHODS AND ANALYSIS: The KoReS study will examine self-help friendliness and cooperation between rehabilitation clinics and self-help associations in Germany, applying a sequential exploratory mixed-methods design. In the first qualitative phase, problem-centred interviews and focus groups are conducted with representatives of self-help-friendly rehabilitation clinics, members of their cooperating self-help groups and staff of self-help clearinghouses involved based on a purposeful sampling. Qualitative data collected will be analysed through content analysis using MAXQDA. The findings will serve to develop a questionnaire for a quantitative second phase. Cross-sectional online studies will survey staff responsible for self-help in rehabilitation clinics nationwide, representatives of self-help groups and staff of self-help clearinghouses. Quantitative data analysis with SPSS will include descriptive statistics, correlation, subgroup and multiple regression analyses. Additionally, a content analysis of rehabilitation clinics’ websites will evaluate the visibility of self-help in their public relations.

ETHICS AND DISSEMINATION: The University Medical Center Hamburg-Eppendorf Local Psychological Ethics Committee at the Center for Psychosocial Medicine granted ethical approval (reference number LPEK-0648; 10.07.2023). Informed consent will be obtained from all participants. Results dissemination will comprise various formats such as workshops, presentations, homepages and publications for the international scientific community, rehabilitation centres, self-help organisations and the general public in Germany. For relevant stakeholders, practical guides and recommendations to implement self-help friendliness will derive from the results to strengthen patient orientation and cooperation between rehabilitation and self-help to promote the sustainability of rehabilitation processes.

ABSTRACT

INTRODUCTION: Smoking cessation in pregnancy remains a public health priority. Our team used the Behaviour Change Wheel to develop the Midwives and Obstetricians Helping Mothers to Quit smoking (MOHMQuit) intervention with health system, leader (including managers and educators) and clinician components. MOHMQuit addresses a critical evidence to practice gap in the provision of smoking cessation support in antenatal care. It involves nine maternity services in New South Wales in a cluster randomised stepped-wedge controlled trial of effectiveness. This paper describes the design and rationale for the process evaluation of MOHMQuit. The process evaluation aims to assess to what extent and how MOHMQuit is being implemented (acceptability; adoption/uptake; appropriateness; feasibility; fidelity; penetration and sustainability), and the context in which it is implemented, in order to support further refinement of MOHMQuit throughout the trial, and aid understanding and interpretation of the results of the trial.

METHODS AND ANALYSIS: The process evaluation is an integral part of the stepped-wedge trial. Its design is underpinned by implementation science frameworks and adopts a mixed methods approach. Quantitative evidence from participating leaders and clinicians in our study will be used to produce individual and site-level descriptive statistics. Qualitative evidence of leaders’ perceptions about the implementation will be collected using semistructured interviews and will be analysed descriptively within-site and thematically across the dataset. The process evaluation will also use publicly available data and observations from the research team implementing MOHMQuit, for example, training logs. These data will be synthesised to provide site-level as well as individual-level implementation outcomes.

ETHICS AND DISSEMINATION: The study received ethical approval from the Population Health Services Research Ethics Committee for NSW, Australia (Reference 2021/ETH00887). Results will be communicated via the study’s steering committee and will also be published in peer-reviewed journals and presented at conferences.

ABSTRACT

OBJECTIVES: Social isolation may affect diabetes self-management. This study aimed to explore the relations between social isolation and glycaemic control in patients with diabetes and to explore lifestyle differences among individuals with different levels of social isolation.

METHODS: The relevant data of 665 people previously diagnosed with diabetes included in the China Health and Retirement Longitudinal Study from 2011 to 2015 were extracted and analysed. The study included patient general information, blood glucose, lipids, glycosylated haemoglobin, social isolation index, health-related lifestyle factors and diabetes-related factors. Differences in metabolic abnormalities and modifiable lifestyles were compared among patients with varying levels of social isolation.

RESULTS: Multiple linear regression analysis demonstrated that among men aged 45-64 years, the high social isolation group had significantly higher glycosylated haemoglobin levels compared with the low isolation group (7.29±1.81 vs 6.59±1.63, p=0.026). A positive correlation was observed between social isolation and blood glucose (β=14.16; 95% CI 2.75 to 25.57; p=0.015) and glycosylated haemoglobin (β=0.35; 95% CI 0.10 to 0.60; p=0.006), indicating that higher social isolation was associated with higher fasting blood glucose and glycosylated haemoglobin levels. However, no significant associations were observed in other age groups. Notably, men aged 45-65 years with high social isolation had higher depression rates (44.10% vs 24.60%, p=0.024), lower engagement in moderate exercise (5.70% vs 23.50%, p=0.019) and shorter 10-minute walks (17.10% vs 36.80%, p=0.027). Differences in other health-related and diabetes-related factors were not statistically significant.

CONCLUSION: Middle-aged men with diabetes with higher social isolation tend to have higher blood glucose and glycosylated haemoglobin levels. This subset of patients requires targeted attention to provide social support from family and friends for improved glycaemic control. If necessary, education on diabetes should be made available to family members and friends.

ABSTRACT

OBJECTIVES: To comprehensively synthesise evidence regarding the validity and reliability of the Anaesthetists’ Non-Technical Skills (ANTS) behavioural marker system and its application as a tool for the training and assessment of non-technical skills to improve patient safety.

DESIGN: Systematic review.

DATA SOURCES: We employed a citation search strategy. The Scopus and Web of Science databases were searched for articles published from 2002 to May 2022.

ELIGIBILITY CRITERIA: English-language publications that applied the ANTS system in a meaningful way, including its use to guide data collection, analysis and reporting.

DATA EXTRACTION AND SYNTHESIS: Study screening, data extraction and quality assessment were performed by two independent reviewers. We appraised the quality of included studies using the Joanna Briggs Institute Critical Appraisal Checklists. A framework analysis approach was used to summarise and synthesise the included articles.

RESULTS: 54 studies were identified. The ANTS system was applied across a wide variety of study objectives, settings and units of analysis. The methods used in these studies varied and included quantitative (n=42), mixed (n=8) and qualitative (n=4) approaches. Most studies (n=47) used the ANTS system to guide data collection. The most commonly reported reliability statistic was inter-rater reliability (n=35). Validity evidence was reported in 51 (94%) studies. The qualitative application outcomes of the ANTS system provided a reference for the analysis and generation of new theories across disciplines.

CONCLUSION: Our results suggest that the ANTS system has been used in a wide range of studies. It is an effective tool for assessing non-technical skills. Investigating the methods by which the ANTS system can be evaluated and implemented for training within clinical environments is anticipated to significantly enhance ongoing enhancements in staff performance and patient safety.
