“The system is a bit broken…” a qualitative exploration of barriers in the pathway for diagnosing Developmental Coordination Disorder

by Lucy H. Eddy, Nat K. Merrick, Cara E. Staniforth, Jade L. Jukes, Liam J. B. Hill, Mark Mon-Williams, Farid Bardid, Rebecca Murray

Background

Approximately 5% of children are affected by a neurodevelopmental disorder of their sensorimotor skills. DSM-V and ICD-10, the two most widely used diagnostic systems, define this diagnostically as ‘Developmental Coordination Disorder’ (DCD) or ‘Specific Developmental Disorder of Motor Function’ (SDDMF), respectively. A diagnosis of DCD has been found to have a detrimental impact on a range of outcomes (e.g., health and education). It is therefore crucial that these children receive timely intervention. This is reliant, however, on effective assessment and support pathways. Research has shown there is great parental dissatisfaction, but there has been limited research exploring a clinical and education perspective. This study therefore aimed to understand barriers and facilitators for clinical and education practitioners in the pathway in a diverse district in the UK (Bradford).

Methods

Semi-structured interviews were completed with stakeholders across the pathway to identify barriers and facilitators to assessing, diagnosing, and supporting children with sensorimotor skill difficulties. Theoretical thematic analysis aligned to the Capability, Opportunity, Motivation model of Behaviour change (COM-B) was used to analyse the qualitative data.

Results

Interviews revealed many barriers in the DCD pathway related to capability (confusing terminology, inconsistent knowledge, inappropriate referrals), opportunity (resource constraints, DCD being considered low priority, and disconnected services), and motivation (overlapping job roles, a desire to consider those with difficulties not eligible for a diagnosis). No facilitators were consistently identified across interviews.

Conclusion

Families face multiple barriers to obtaining a diagnosis for their child through existing clinical pathways for assessment and support. These findings are unlikely to be unique to Bradford, due to international research highlighting these issues via parental interviews. These findings therefore may reflect challenges both nationally and internationally within DCD pathways. There is an urgent need for: (i) clear communication across different services (with consistency in terminology), and (ii) a more collaborative and integrated approach to assessment, diagnosis, and support in order to help these children thrive.

by Md. Masud Reza, Hasibul Hasan Shanto, Samira Dishti Irfan, A. K. M. Masud Rana, Mohammad Niaz Morshed Khan, Golam Sarwar, Mohammad Sha Al Imran, Mahbubur Rahman, Md. Safiullah Sarker, Muntasir Alam, Md. Abu Hena Chowdhury, Mustafizur Rahman, Sharful Islam Khan

Background

Unintended pregnancy among female sex workers (FSW) is a pressing reproductive health concern attributable to risky sexual behaviors, healthcare inequities and poor negotiation powers with male sex partners. However, evidence is scarce on the prevalence and determinants of unintended pregnancies among FSW, which is crucial for enhancing reproductive healthcare. This analysis aims to measure the prevalence of lifetime unintended pregnancies and their associated factors.

Methods

A cross-sectional study was conducted on 327 FSW in Jashore (a border belt district of Bangladesh) from September 2022 to March 2023. Participants were recruited through take-all sampling. Data were collected on the lifetime history of unintended pregnancies and other relevant variables through face-to-face interviews. Chi-square statistic was used to compare the characteristics of FSW reporting unintended pregnancies. To assess the net association of factors associated with unintended pregnancy, multiple logistic regression was applied.

Result

The lifetime prevalence of unintended pregnancies was reported at 75.8% (95%CI: 71.0–80.1). Among those who reported unintended pregnancies, 37.1% (95%CI: 30.8–43.8) had no education, 39.9% (95%CI: 32.8–47.5) were 25–34 years old, 49.6% (95%CI: 39.3–59.9) were currently married and 62.9% (95%CI: 49.7–74.4) earned ≤10,000 BDT per month compared to those who did not report lifetime unintended pregnancies. The likelihood of unintended pregnancies was significantly higher among those who reported having sex with non-transactional male sex partners (AOR: 2.4, 95%CI: 1.1–5.3, p = 0.036) than those who never had sex with any non-transactional male sex partner. The likelihood was also higher among those who reported rape in their lifetime (AOR: 2.0, 95%CI: 1.0–3.8, p = 0.037) and who self-reported mental health problems (AOR: 2.1, 95%CI: 1.0–4.2, p = 0.045) within the past year, compared to their counterparts.

Conclusion

This study highlights the considerable prevalence and associated determinants of unintended pregnancies among FSW in Jashore. These determinants need to be considered to strengthen reproductive healthcare interventions and policies for FSW. Reproductive health of FSW cannot be improved unless these factors are addressed in the ongoing interventions.

Ectoparasite abundance and pathogen prevalence of the San Clemente Island fox (<i>Urocyon littoralis clementae)</i>

by David A. Green, Jesse M. Maestas, Jessica N. Sanchez, Nathan C. Nieto, Andrew S. Bridges, David K. Garcelon

The San Clemente Island fox (Urocyon littoralis clementae) is classified as a focal species for conservation management by the US Navy. They are considered vulnerable to a variety of vector-borne diseases due to their relatively high population density and low genetic diversity. During the dry (July–November) and wet (December–February) seasons of 2017–2018 we live-trapped 95 foxes and collected ectoparasites to test for the presence of pathogens. We found a significant difference in ectoparasite abundance on foxes between seasons, but no differences associated with sex or age. We found that foxes carried two species of flea (Echidnophaga gallinacea and Orchopeas howardi) and two tick species (Ixodes pacificus and Ixodes jellisoni). No evidence of Borrelia burgdorferi, Anaplasma phagocytophilum, or Borrelia miyamotoi bacteria were found. This paper is the first account of ectoparasite species identification, quantification, and pathogen testing for the San Clemente Island fox subspecies.

Effect of race and sex on lupus diagnosis in primary care: A randomized factorial survey study

by Alyssa Howren, Quan L. Tran, Sadaf Sediqi, Saadiya Hawa, Douglas K. Owens, Eleni Linos, Titilola O. Falasinnu, Yashaar Chaichian, Julia F. Simard

Background

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune rheumatic disease whose epidemiology and clinical prognosis vary by race and sex. Observed disparities in SLE may be partly attributable to cognitive processes in clinical decision-making, which can influence diagnostic accuracy and clinical management. We aimed to examine variation in primary care physicians’ (PCP) diagnosis and management of SLE when all content of a clinical case is identical, apart from race and sex.

Methods

We distributed an online randomized factorial survey from 04/11/2024–06/10/2024 to PCPs across the US. Participants were presented with one of four possible SLE vignettes – Black female, White female, Black male, White male – for which all other clinical content was identical. Block randomization was used to randomly modify the race (Black/White) and sex (female/male) of the SLE “case”. Primary outcomes were correct text-based responses for SLE diagnosis at initial case presentation and after reviewing additional lab results. Secondary outcomes were participants’ review time and planned next steps (treatment, referral, tests) as a proxy for cognitive bias and certainty, respectively. We calculated descriptive statistics for all outcomes stratified by assigned randomized factor and used chi-square tests to evaluate between-group differences.

Results

1031 PCPs (42.7% women, mean age 52.1 ± 12.1 years) completed the case. At initial presentation, 63.9% of participants correctly identified SLE as a differential diagnosis. An initial diagnosis of SLE significantly differed by the race and sex of the case (p  Conclusion

A patient’s race and sex may influence diagnostic accuracy and clinical decision-making for SLE in primary care. The observed variation in diagnostic accuracy, which aligns with the descriptive epidemiology of SLE, highlights the need for targeted interventions to ensure equitable diagnostic processes.

Conplastic FVB/N-mt129S6/SvEvTac mice: A new tool for cancer research

by Artiom Gruzdev, Wendy N. Jefferson, Thomas B. Hagler, Gregory J. Scott, Manas K. Ray, Ginger W. Muse, Rani S. Sellers, Carmen J. Williams

FVB/N mice, which are commonly used for cancer studies, have accelerated onset of endometrial cancer following developmental estrogenic chemical exposure. These mice also have a polymorphism in the mitochondrial gene, mt-Atp8, leading to increased production of reactive oxygen species. We hypothesized that this polymorphism contributes to the enhanced endometrial cancer phenotype in FVB/N mice. To test this idea, we generated conplastic FVB/N-mt129S6/SvEvTac mice (FVB/N nuclear genome; 129S6/SvEvTac mitochondria: FVB/N-mt129). The impact of 129S6 versus FVB/N mitochondrial genomes on endometrial cancer development following neonatal exposure to the xenoestrogen, diethylstilbestrol, was tested by comparing the cancer phenotypes of FVB/N mice to FVB/N-mt129 mice. There was no difference in cancer incidence regardless of mitochondria source, but cancer grade was higher in the conplastic strain. Additionally, while the FVB/N genetic background is considered non-permissive for generation of pluripotent mouse embryonic stem cells, blastocysts from the conplastic background readily generated mouse embryonic stem cell clones that supported gene editing in culture and subsequently generated germline competent chimeric founder mice. FVB/N-mt129 mice are a potentially powerful resource for generating germline competent embryonic stem cells with an FVB/N nuclear genome and for studying cancer phenotypes.

Testing oral nicotine pouches versus nicotine replacement therapy for cigarette harm reduction in Appalachia: The ARISE study protocol

by Amy Wermert, Theodore M. Brasky, Alison M. Newton, Alice Hinton, Hayley Curran, Amy K. Ferketich, Matthew J. Carpenter, Peter G. Shields, Patrick Tomko, Theodore L. Wagener, Brittney Keller-Hamilton

Background

With the highest cancer incidence and mortality rates in the country, rural Appalachia has experienced a decades-long health decline, due in part to high smoking rates. Cigarette smoking prevalence exceeds 30% in much of the region. Oral nicotine pouches (ONPs), which contain nicotine but no tobacco, present an unexplored opportunity to reduce cigarette smoking and cancer incidence.

Objectives

We outline the protocol for the Appalachian Research to Impact Smoking’s Effects (ARISE) study, a randomized controlled trial to determine whether ONPs affect cigarette smoking patterns short- and long-term, and to evaluate their abuse liability versus nicotine replacement therapy (NRT) in a large sample of Appalachian smokers (clinicaltrials.gov: NCT06763536).

Methods

Between 2025 and 2029, we will recruit 1,000 adult smokers living in rural Appalachian counties across 11 states. Participants will be identified via media outreach, mobile cancer screening, community events, and respondent-driven sampling, then randomized to ONP or NRT and complete four study phases: Baseline, Sampling, Switch, and Observation. In the Sampling phase, participants will receive varied flavors and nicotine strengths of their assigned product and select preferred options for use. During the Switch Phase, they will attempt to quit smoking and switch completely to their assigned product. The Observation phase will monitor tobacco use after discontinuation of study products. Study procedures will be conducted online and by mail, including surveys, expired carbon monoxide verification, and product delivery. The primary outcome is 7-day biochemically verified cigarette abstinence at the end of the Switch Phase. Secondary outcomes include switching rates, product appeal, craving, withdrawal, dependence, and purchases during the Observation phase. An intention-to-treat log-binomial regression model will estimate the effect of intervention assignment on cigarette abstinence.

Conclusions

Results will inform whether and how ONPs should be regulated, approached clinically, and used in public health interventions to reduce the burdens of cigarette smoking in Appalachia.

by Saleh A. Alqahtani, Shadan AlMuhaidib, Dimitri A. Raptis, Waleed K. Al-Hamoudi, K. Rajender Reddy, Dieter C. Broering, Saad A. Alghamdi, The OTCE Collaborative

Background

Liver transplantation (LT) represents the life-saving treatment for advanced liver disease. We aim to investigate LT indication trends and outcomes in Saudi Arabia, following the evolution of effective therapies for hepatitis C virus (HCV) and the rising fatty liver disease prevalence.

Methods

We retrospectively analyzed data from adult patients who underwent LT from 2011 to 2023 at a tertiary referral center in Saudi Arabia. We assessed demographics, LT indication trends, Model for End-stage Liver Disease (MELD) scores, donor type, and survival outcomes.

Results

A total of 1,419 patients were included. The median age was 56.9 years, with 37.4% female. Living donor LT (LDLT) represented 79.8% of all transplants, and 22.0% of recipients had hepatocellular carcinoma (HCC). Metabolic dysfunction-associated steatohepatitis (MASH) was the predominant indication for LT (33.2%), followed by HCV (18.0%) and hepatitis B virus (HBV) (17.1%). Overall survival rates at 1-, 2-, 3-, 5-, and 10-years post-transplantation were 87.9%, 85.0%, 82.4%, 77.7%, and 71.3%, respectively. Hazard ratios (HR) for mortality were lower in patients with HBV compared to MASH (HR: 0.44, 95% CI: 0.28–0.69, p  Conclusions

MASH represents the leading indication for LT in this large cohort, necessitating preventive strategies and early detection efforts.

Integrated knowledge translation (iKT) in preclinical research: A scoping review protocol

by Georgia Black, Reena Besa, Daniel Blumberger, Heather Brooks, Graham Collingridge, John Georgiou, Evelyn K. Lambe, Clement Ma, Bernadette Mdawar, Tarek K. Rajji, Sanjeev Sockalingam, Cara Sullivan, Quincy Vaz, Zhengbang Yao, Branka Agic

Introduction

Integrated knowledge translation (iKT) is a collaborative research approach that emphasizes the meaningful and active participation of knowledge users throughout the research process. Evidence suggests that integrated knowledge translation has the potential to increase the relevance, applicability, and use of research findings. This approach has been increasingly utilized in health research in recent years. However, the extent to which it has been applied in preclinical research and its effectiveness are unknown. To address this gap, we will conduct a scoping review to map the current use, potential benefits, and challenges of iKT in preclinical research.

Methods

Guided by a modified Arksey and O’Malley’s scoping review framework, we will systematically search reference lists and key research databases including Medline, Embase, PsycINFO, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, and Web of Science. Peer-reviewed articles written or translated in English that focus on iKT or approaches that align with iKT within the context of preclinical research will be included. This review will be conducted as part of the Improving Neuroplasticity through Spaced Prefrontal intermittent-Theta-Beta-Stimulation REfinement in Depression (INSPiRE-D) project, which features preclinical research from mouse models to human work (Grant number CAMH File No.22-060). The project’s multidisciplinary team and knowledge user advisory committee will be consulted at key points throughout the scoping review process. A person with lived experience co-chairs the project advisory committee, co-authored this manuscript, and will be routinely included in the decision-making process of the scoping review.
