Request AccessCharacteristics and primary care experiences of people who self-report as autistic: a probability sample survey of adults registered with primary care services in England.
BMJ OpenLittle is known about adults who self-report as autistic. This study aimed to profile the demographic characteristics, long-term health conditions and primary care experiences of adults who self-report as autistic (including those with and without a formal diagnosis).
623 157 survey respondents aged 16 and over, including 4481 who self-report as autistic.
A total of 4481 of the 623 157 survey participants included in the analysis self-reported autism, yielding a weighted proportion estimate of 1.41% (95% CI 1.35% to 1.46%). Adults self-reporting as autistic were more likely to be younger, male or non-binary, to identify as a gender different from their sex at birth, have a non-heterosexual sexual identity, be of white or mixed or multiple ethnic groups, non-religious, without caring responsibilities, unemployed, live in more deprived areas and not smoke. All chronic conditions covered were more prevalent among adults self-reporting as autistic, including learning disability, mental health conditions, neurological conditions, dementia, blindness or partial sight and deafness or hearing loss. Adults self-reporting as autistic were also less likely to report a positive experience of making an appointment (adjusted OR (aOR) 0.90, 95% CI 0.82 to 0.98) and navigating GP practice websites (aOR 0.78, 95% CI 0.70 to 0.87) and more likely to report seeking advice from a friend or family member prior to making an appointment (aOR 1.25, 95% CI 1.14 to 1.38) and having a preferred GP (aOR 2.25, 95% CI 2.06 to 2.46). They were less likely to report that their needs were met (aOR 0.73, 95% CI 0.65 to 0.83).
Adults self-reporting as autistic have a distinctive sociodemographic profile and heightened rates of long-term conditions. They report challenges in both accessing primary care and having their needs met when they do. These findings should inform future care initiatives designed to meet the needs of this group.
Knowledge of and attitude towards depression among urban and rural residents in Beijing: a cross-sectional study.
BMJ OpenTo compare the level of knowledge of depression, recognition ability and attitudes towards depression among urban and rural residents in Beijing.
A total of 6463 participants aged 18 years and above who had lived for more than 6 months over the last year in Beijing were selected in this study.
A total of 2554 urban and 2043 rural residents completed the survey. Urban residents of Beijing exhibited a higher average total score on the Depression Knowledge Questionnaire [(20.4±3.3) vs (18.7±3.5), p<0.001] and a higher rate of correctly identifying individuals with depression (47.9% vs 36.6%, p<0.001) than their counterparts in rural areas. Residents who correctly identified people with depression had higher scores on the Depression Knowledge Questionnaire. Depression knowledge varied significantly among urban and rural residents. The multivariate linear regression analysis revealed that rural residents scored significantly lower on measures of depression knowledge compared with urban residents (B=-0.83, 95%CI=-1.03 to -0.63, p<0.001). Older individuals (aged 50+) showed lower understanding compared with the 18-49 age group, with significant negative regression coefficients (Urban: B=-1.06, Rural: B=-1.35, both p<0.001). Higher educational levels were positively associated with greater depression knowledge (Urban: B=1.40, Rural: B=1.21, both p<0.001). Employment was linked to higher knowledge levels than unemployment (Urban: B=-0.60, Rural: B=-0.58, both p=0.00). A monthly income of 8000 yuan or more correlated with better depression understanding than lower incomes (Urban: B=0.81, Rural: B=1.04, both p<0.001). Additionally, in urban areas, unmarried residents scored higher in depression knowledge than those divorced (B=-0.55, p=0.04). Residents in urban areas had relatively positive attitudes towards individuals with depression.
Rural residents of Beijing had lower levels of knowledge and recognition of depression and more negative attitudes towards individuals with depression than those from urban areas. The health authority needs to focus on the poor level of knowledge and increase mental health resources in rural areas as a priority site for future psychological popularisation efforts.
Association between ambient temperature and economic burden of unintentional injury in Tianjin: a case-crossover study.
BMJ OpenUnintentional injuries constitute a significant global public health issue with significant social and economic costs. Previous evidence suggests ambient temperatures are associated with unintentional injury occurrences. However, the impacts of ambient temperature on unintentional injury economic burden have received little research attention. The objective of the study was to examine the association between ambient temperature and economic burden of unintentional injury.
The association between ambient temperature and unintentional injury hospitalisation was evaluated with a distributed lag non-linear model, further temperature-attributable economic burden of unintentional injuries was quantified, and adjusted for demographic characteristics, injury mechanism and injury location of injury.
The temperatures below 11.5°C were significantly associated with the increased risk of unintentional injury hospitalisation in Tianjin, in 2021. The effect was maximised on the current day. The relatively low temperature was responsible for 25.44% (95% CI 13.74, 33.09) of unintentional injury patients, and was associated with the number of unintentional injury patients (3114, 95% CI 1608, 4036). The relatively low temperature was associated with the excess economic burden for unintentional injury (¥197.52 million, 95% CI 102.00, 256.00; about 27.10 million dollars), accounting for 26.49% of the total economic burden. The cold temperatures generally had greater impacts on males (¥136.46 million, 95% CI 83.28, 172.42; about 18.67 million dollars) and the elderly (¥74.35 million, 95% CI 14.87, 102.14; about 10.24 million dollars).
The temperature was associated with approximately 3000 unintentional injury patients and ¥200 million (27 million dollars), accounting for 26% of the total economic burden in Tianjin, 2021.
Addressing diagnostic uncertainty and excellence in emergency care-from multicountry policy analysis to communication practice in Australian emergency departments: a multimethod study protocol.
BMJ OpenThe project has received ethical approvals from the Human Research Ethics Committee at ACT Health, Northern Sydney Local Health District and the Australian National University. Findings will be disseminated to academic peers, clinicians and healthcare consumers, health policy-makers and the general public, using local and international academic and consumer channels (journals, evidence briefs and conferences) and outreach activities (workshops and seminars).
This project uses a qualitatively driven multimethod design integrating findings from two research studies to gain a comprehensive understanding of the impact of context and communication on diagnostic excellence from diverse perspectives. Study 1 will map the diagnostic policy and practice landscape in Australia, New Zealand and the USA through qualitative expert interviews and policy analysis. Study 2 will investigate the communication of uncertainty in diagnostic interactions through a qualitative ethnography of two metropolitan Australian ED sites incorporating observations, field notes, video-recorded interactions, semistructured interviews and written medical documentation, including linguistic analysis of recorded diagnostic interactions and written documentation. This study will also feature a description of clinician, patient and carer perspectives on, and involvement in, interpersonal diagnostic interactions and will provide crucial new insights into the impact of communicating diagnostic uncertainty for these groups. Project-spanning patient and stakeholder involvement strategies will build research capacity among healthcare consumers via educational workshops, engage with community stakeholders in analysis and build consensus among stakeholders.
Voluntary sector specialist service provision and commissioning for victim-survivors of sexual violence: results from two national surveys in England.
BMJ OpenIn England, voluntary sector specialist (VSS) services are central to supporting victim-survivors of sexual violence (SV). However, empirical evidence is lacking about the scope, range and effectiveness of VSS provision for SV in England.
To undertake national surveys to map SV VSS service provision and describe arrangements for funding and commissioning.
Senior staff working in VSS services and commissioners from multiple organisations were surveyed electronically. Surveys explored SV service commissioning, funding and delivery, partnerships between organisations, perceived unmet need for services, and views about facilitators and challenges. Data were analysed descriptively to characterise VSS service provision for SV and commissioning across England.
54 responses were received from VSS providers and 34 from commissioners. Data demonstrated a complex and evolving funding and commissioning landscape in which providers typically secured funding from multiple sources, impacting consistency and scope of service provision. It was common for multiple organisations to co-commission services, demonstrating trends towards larger contracts that may disadvantage smaller specialist providers. Numerous examples of partnership working between organisations were identified, although developing partnerships was noted as challenging, particularly between VSS organisations. There was clear evidence of unmet need for services, with some groups of victim-survivors such as those from black and minority ethnic groups, often underserved by specialist services. However, there was also evidence of innovative service development and commissioning approaches to meet the needs of victim-survivors who face challenges accessing services.
This study provides novel insights into SV service provision and commissioning in England, including unmet needs among victim-survivors.
Occupational exposure and new-onset asthma in the population-based Telemark study: a 5-year follow-up.
BMJ OpenThis study aimed to estimate the incidence of asthma and assess the association between job exposure matrix (N-JEM) assigned occupational exposure, self-reported occupational exposure to vapour, gas, dust and fumes (VGDF), mould, damages from moisture and cold, and new-onset asthma. We also aimed to assess the corresponding population attributable fraction (PAF) for ever exposure to VGDF.
New-onset asthma and its association with self-reported occupational exposure to VGDF, data from the N-JEM and self-reported workplace conditions were assessed using logistic regression adjusted for gender, age, smoking and body mass index. The PAF was calculated using the PUNAF command in STATA.
There were 266 (3.7%) cases of new-onset asthma and an incidence density of 7.5 cases per 1000 person-years. A statistically significant association was found for ever exposed to VGDF with an OR of 1.49 (95% CI 1.15 to 1.94), weekly OR 2.00 (95% CI 1.29 to 3.11) and daily OR 2.46 (95% CI 1.39 to 4.35) exposure to VGDF. The corresponding PAF for ever exposed to VGDF was 17% (95% CI 5.4% to 27.8%) and the risk of asthma onset increased with frequent VGDF exposure, indicating a possible exposure-response relationship (p=0.002 for trend). The N-JEM exposure group, accidental peak exposure to irritants had an increased risk of new-onset asthma, OR 2.43 (95% CI 1.21 to 4.90). A significant association was also found for self-reported exposure to visible damages due to moisture 1.51 (95% CI 1.08 to 2.11), visible and smell of mould 1.88 (95% CI 1.32 to 2.68), 1.55 (95% CI 1.12 to 2.16) and cold environment 1.41 (95% CI 1.07 to 1.86).
Participants had elevated ORs for asthma associated with self-reported and N-JEM-assigned exposures. A PAF of 17% indicates that work-related asthma is still common. The possible exposure-response relationship suggests that reducing occupational VGDF exposure frequency could prevent the onset of asthma.
Effectiveness of moisturising therapy in treating nipple trauma: a systematic review protocol.
BMJ OpenEthics approval is not required for this study. The findings of this review will be disseminated through academic publications, detailed reports and presentations at relevant conferences.
This systematic review protocol adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines and is registered in the International Prospective Register of Systematic Reviews. The focus will be on both randomised and non-randomised controlled trials addressing the treatment of nipple trauma in lactating women. In this context, 'moisturising therapy' is categorised as a non-pharmacological intervention applied directly to the nipple, excluding treatments for bacterial or fungal infections. The primary outcomes will include measures of the healing efficiency of nipple trauma and reduction in nipple pain. Searches will be conducted without date restrictions across multiple databases, including PubMed, CINAHL, the Cochrane Library, Web of Science, CiNii Research and Ichushi-Web, in addition to exploration of grey literature. Two independent reviewers will manage all stages of the review process, under the supervision of a third reviewer. Data extraction will encompass participant demographics, study methodologies, sample specifics and measured outcomes. Quality assessment will be conducted using the Joanna Briggs Institute Appraisal Checklist Tools.

Newborn community health advancements among Ethiopian Orthodox Christian women in North Gondar, Ethiopia: community-based randomised trial protocol.
BMJ OpenNCT05111899.
The study designed is a community-randomised trial conducted in the Central Gondar area. The behaviour change intervention pairs trained Orthodox priests with members of the Health Development Army to conduct community health outreach by identifying near-term pregnant women in their communities and educating them on the topics of exclusive breast feeding, immunisation, nutrition and uptake of available child healthcare services. The evaluation of the intervention will enrol up to 150 newborn-mother pairs from communities receiving the behaviour change intervention and another 150 pairs enrolled from control communities. The quantitative analysis will be done by comparing data between the intervention and control groups related to breast feeding, anthropometry, immunisation status and uptake of child health services. The primary outcomes are exclusive breastfeeding through 6 months, mid-upper arm circumference, completion of vaccinations and infant hospitalisation.
Cohort profile: DNA methylation in the Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) - recruitment and participant characteristics.
BMJ OpenEpigenetic modifications including DNA methylation (DNAm) are proposed mechanisms by which social or environmental exposures may influence health and behaviours as we age. The Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) DNAm cohort, established in 2013, is one of several worldwide, nationally representative prospective studies of ageing with biological samples from participants who consented to multiomic analysis.
NICOLA recruited 8478 participants (8283 aged 50 years or older and 195 spouses or partners at the same address aged under 50 years). Computer-Assisted Personal Interviews, Self-Completion Questionnaires and detailed Health Assessments (HA) were completed. Of the 3471 (44.1%) participants who attended the HA in wave 1, which included venous blood sampling, 2000 were identified for the DNAm cohort. Following technical and data quality control checks, DNAm data are currently available for n=1870.
There was no significant difference based on age, self-reported gender, education, employment, smoking or alcohol status and subjective health reports between the DNAm cohort and other HA attendees. Participants were more likely to be in the DNAm group if they lived with one other person (OR 1.26, 95% CI 1.07 to 1.49). The DNAm group had a lower proportion of depressed participants and those meeting criteria for post-traumatic stress disorder (11.7% and 4.4% vs 13.5% and 4.5%, respectively) categorised by objective assessment tools but this was not significant (OR 0.84, 95% CI 0.69 to 1.02 and OR 0.87, 95% CI 0.64 to 1.19).
The deeply phenotyped DNAm cohort in NICOLA with planned prospective follow-up and additional multiomic data releases will increase the cohort's utility for research into ageing. The genomic and epigenetic data for the DNAm cohort has been deposited on the European Genome-Phenome Archive, increasing the profile of this cohort and data availability to researchers.
Investigating the efficacy of acupuncture in treating patients with metabolic-associated fatty liver disease: a protocol for a randomised controlled clinical trial.
BMJ OpenChiCTR2300075701.
This will be a multicentre, randomised and sham-controlled trial. Ninety-eight participants with MAFLD will be enrolled in this trial. Participants will be randomly assigned in a 1:1 ratio to receive acupuncture or SHA for 12 weeks. The primary outcome is the rate of patients with a 30% relative decline in liver fat after 12 weeks of treatment in MRI-proton density fat fraction (MRI-PDFF), which will be obtained by quantitative chemical shift imaging such as the multipoint Dixon method at 0, 12 and 24 weeks. Secondary outcomes include the changes in the relative liver fat content measured by MRI-PDFF, magnetic resonance elastography, liver function, lipid metabolism, homeostatic model assessment for insulin resistance (HOMA-IR) and serum high sensitivity C reactive protein, which will be obtained at 0, 6, 12 and 24 weeks. Body measurement indicators (body mass index, waist circumference, hip circumference and waist-to-hip ratio) will be obtained at 0, 3, 6, 9, 12 and 24 weeks. The alteration in the gut microbiota composition and its metabolism will be assessed by 16S ribosomal RNA sequencing and liquid chromatography-mass spectrometry at 0 and 12 weeks.

BMJ OpenThe review involves the assessment of morphological variations in the temporomandibular joint (TMJ) and its associated structures in patients with temporomandibular disorder.
Ethical approval is not applicable for this study since this involves analysis of secondary data. Results will be disseminated through peer-reviewed publications and cnference presentations. A comprehensive summary of morphological alterations in TMJ is essential for assessing risk factors, accurate diagnosis, treatment planning and will collectively contribute to enhanced clinical care and overall patient well-being.
Systematic searches for relevant studies will be carried out in multiple databases. Sources will include MEDLINE, Scopus, Dentistry and Oral Sciences Source, Cochrane CENTRAL, CINAHL, Web of Science, ProQuest Dissertation and Thesis and Google Scholar. The databases will be searched from inception to November 2023. Analytical observational studies comprising retrospective and prospective cohort studies, case-control studies and analytical cross-sectional studies will be selected and critical appraisal will be performed. No restrictions will be imposed on the date and country of publication. Joanna Briggs Institute (JBI) guidelines for systematic effectiveness reviews will be followed for data appraisal, extraction and synthesis. The strength of evidence will be graded using the Grading of Recommendations, Assessment, Development and Evaluation method and the summary of findings will be created using GRADEpro software.
The protocol is registered in PROSPERO: CRD42023448882.
Temporal trends in mortality and causes of death in patients with incident atrial fibrillation: a nationwide register study from 2010 to 2018.
BMJ OpenAtrial fibrillation (AF) is associated with increased mortality. Previous studies have reported conflicting results in temporal trends of mortality after AF diagnosis. We aim to address this disparity by investigating the 1-year mortality and causes of death in Finnish patients diagnosed with AF between 2010 and 2017.
1-year all-cause, cardiovascular (CV) and cause-specific mortality following AF diagnosis.
The study cohort consisted of 157 658 incident AF cases (50.1% male, mean age 72.9 years). Both all-cause and CV mortality declined from cohort entry years 2010-2017 (from 12.9% to 10.6%, mortality rate ratio (MRR) 0.77; 95% CI 0.73 to 0.82 in cohort entry year 2017 with 2010 as reference; and from 7.4% to 5.2%, MRR 0.68; 95% CI 0.63 to 0.74, respectively). Overall mortality and CV mortality were lower in women than in men throughout the study period (MRR 0.66; 95% CI 0.63 to 0.69 and MRR 0.53; 95% CI 0.50 to 0.56, respectively). Deaths attributable to ischaemic heart disease decreased during the study period (from 30.7% to 21.6%, MRR 0.51; 95% CI 0.49 to 0.62 in 2017 vs 2010), whereas dementia and Alzheimer's disease increased as a cause of death over time (6.2% to 9.9%, MRR 1.19; 95% CI 0.96 to 1.48 in 2017 vs 2010). The CHA2DS2-VASc score associated strongly with 1-year survival (p<0.0001).
Our study reiterates that mortality after diagnosis of AF has decreased. The CHA2DS2-VASc score highlights the need to treat comorbidities as it strongly associates with patient 1-year survival after initial AF diagnosis.
