Bacteria isolated from the grape phyllosphere capable of degrading guaiacol, a main volatile phenol associated with smoke taint in wine

by Claudia Castro, Jacquelyn Badillo, Melissa Tumen-Velasquez, Adam M. Guss, Thomas S. Collins, Frank Harmon, Devin Coleman-Derr

Recent wildfires near vineyards in the Pacific United States have caused devastating financial losses due to smoke taint in wine. When wine grapes (Vitis vinifera) are exposed to wildfire smoke, their berries absorb volatile phenols derived from the lignin of burning plant material. Volatile phenols are released during the winemaking process giving the finished wine an unpleasant, smokey, and ashy taste known as smoke taint. Bacteria are capable of undergoing a wide variety of metabolic processes and therefore present great potential for bioremediation applications in many industries. In this study, we identify two strains of the same species that colonize the grape phyllosphere and are able to degrade guaiacol, a main volatile phenol responsible for smoke taint in wine. We identify the suite of genes that enable guaiacol degradation in Gordonia alkanivorans via RNAseq of cells growing on guaiacol as a sole carbon source. Additionally, we knockout guaA, a cytochrome P450 gene involved in the conversion of guaiacol to catechol; ΔguaA cells cannot catabolize guaiacol in vitro, providing evidence that GuaA is necessary for this process. Furthermore, we analyze the microbiome of berries and leaves exposed to smoke in the vineyard to investigate the impact of smoke on the grape microbial community. We found smoke has a significant but small effect on the microbial community, leading to an enrichment of several genera belonging to the Bacilli class. Collectively, this research shows that studying microbes and their enzymes has the potential to identify novel tools for alleviating smoke taint.

Investigating the use and impact of community Care (Education) and Treatment Reviews (C(E)TRs) in people with intellectual disability and autistic people: protocol for a cohort study using electronic health records

Por: McCoy · B. · Bell · L. · Wang · K. · Jin · H. · Hassiotis · A. · Strydom · A. · Downs · J. · Carter · B. · Shetty · H. · Stewart · R. · Ali · A. · Sheehan · R. — Octubre 1st 2025 at 08:29
Introduction

Care (Education) and Treatment Reviews (C(E)TRs) are intended to reduce unnecessary psychiatric hospital admission and length of stay for people with intellectual disability and autistic people. The use and impact of C(E)TRs have not been systematically evaluated since their introduction in England in 2015. The aims of this study are to describe the demographic and clinical profiles of people who receive a community C(E)TR and to investigate their effects on admission, length of hospital stay and clinical and functional change.

Methods and analysis

We will conduct a retrospective cohort study using de-identified data from electronic health records derived from two large National Health Service mental health providers in London, England, including one replication site. Data will be extracted using the Clinical Record Interactive Search (CRIS) tool for all people with recorded intellectual disability and/or autism who received mental healthcare from 2015. We will identify community C(E)TR events using keyword searches. Community C(E)TRs will be examined in two ways: (1) In a community cohort, we will capture data in the 6-month periods before and after a community C(E)TR and compare this to a matched control group and (2) In a hospital cohort, we will compare groups who did and did not receive a community C(E)TR prior to their admission. We will describe the socio-demographic and clinical profiles of each group and their health service use, and compare C(E)TR and no C(E)TR groups using t-tests (or a non-parametric equivalent). The primary outcomes are admission to a psychiatric hospital (community cohort) and length of psychiatric hospital admission and clinical change (hospital cohort). Admission to psychiatric hospital will be estimated using propensity score weighting and difference-in-differences methods. Cox’s proportional hazard model will be used for length of hospital admission and repeated-measures analysis of variance (ANOVA) will be used to assess clinical change.

Ethics and dissemination

Use of CRIS to examine de-identified clinical data for research purposes has overarching ethical approval. This study has been granted local approval by the South London and Maudsley CRIS Oversight Committee. Findings will be disseminated in an open-access peer-reviewed academic publication, at conference presentations, and to service users and carers in accessible formats.

Determining the indirect costs of suicide in Sweden: a national population-based cross-sectional study, 2010-2019

Por: Wikström · D. · Nystrand · C. · Hadlaczky · G. · Gedin · F. — Septiembre 29th 2025 at 07:52
Objectives

Globally, more than 700 000 people commit suicide annually. In Sweden, the yearly incidence ranges between 1000 and 1500 people, which is higher than the global average. The aim of this study is to estimate the economic burden related to indirect costs that suicide has imposed on Swedish society between 2010 and 2019.

Design

National population-based cross-sectional study.

Participants and setting

All suicides in Sweden between 2010 and 2019, using data from the Swedish National Cause of Death Registry.

Outcomes

Indirect costs associated with suicides, estimated using the human capital approach, including productivity loss over 1-year and lifetime horizons.

Results

Between 2010 and 2019, 1406 to 1591 suicides occurred annually in Sweden, resulting in approximately 26 500 productive life years lost each year. In 2019, the productivity loss due to suicides was estimated at 44 million over a 1-year horizon and 935 million over a lifetime horizon. The corresponding per-person costs were 37 000 and 778 000, respectively.

Conclusions

This study provides valuable insights into the economic burden of suicide on Swedish society. It underlines the potential economic benefits of effective suicide prevention, aligning with previous research highlighting the substantial returns—both monetary and in terms of human well-being—that successful prevention strategies can yield.

A Borate‐Based Bioactive Glass Advances Wound Healing in Non‐Healing Wagner Grade 1 Diabetic Foot Ulcers: A Randomised Controlled Clinical Trial

ABSTRACT

A novel advanced synthetic bioactive glass matrix was studied in patients with non-healing diabetic foot ulcers (DFUs). Bioactive glasses can be constructed to be biocompatible, with water-soluble materials in multiple geometries including fibre scaffolds that mimic the 3D architecture of a fibrin clot. In this trial, chronic, Wagner Grade 1 DFUs were randomised to receive borate-based bioactive glass Fibre Matrix (BBGFM) plus standard of care (SOC) therapy for 12 weeks or SOC alone. The primary study endpoint was the proportion of subjects that obtained complete wound closure at 12 weeks. Secondary endpoints included time to achieve complete wound closure at 12 weeks. In the modified intent-to-treat (mITT) analysis, 48% (32/67) treated with BBGFM plus SOC healed at 12 weeks compared to 24% (16/66) with SOC alone (p = 0.007). In the per protocol (PP) population, 73% (32/44) of subjects treated with BBGFM plus SOC healed versus 42% (16/38) in the SOC group (p = 0.007). Based on the success of this trial, BBGFM demonstrates faster healing of DFUs compared to SOC and should be considered in the treatment armamentarium for Wagner Grade 1 DFUs. Future trials should investigate the use of BBGFM for healing deeper chronic DFUs, other wound aetiologies, or complex surgical wounds.

Single-centre, prospective cohort to predict optimal individualised treatment response in multiple sclerosis (POINT-MS): a cohort profile

Por: Christensen · R. · Cruciani · A. · Al-Araji · S. · Bianchi · A. · Chard · D. · Fourali · S. · Hamed · W. · Hammam · A. · He · A. · Kanber · B. · Maccarrone · D. · Moccia · M. · Mohamud · S. · Nistri · R. · Passalis · A. · Pozzilli · V. · Prados Carrasco · F. · Samdanidou · E. · Song · J. · W — Septiembre 25th 2025 at 11:09
Purpose

Multiple sclerosis (MS) is a chronic neurological condition that affects approximately 150 000 people in the UK and presents a significant healthcare burden, including the high costs of disease-modifying treatments (DMTs). DMTs have substantially reduced the risk of relapse and moderately reduced disability progression. Patients exhibit a wide range of responses to available DMTs. The Predicting Optimal INdividualised Treatment response in MS (POINT-MS) cohort was established to predict the individual treatment response by integrating comprehensive clinical phenotyping with imaging, serum and genetic biomarkers of disease activity and progression. Here, we present the baseline characteristics of the cohort and provide an overview of the study design, laying the groundwork for future analyses.

Participants

POINT-MS is a prospective, observational research cohort and biobank of 781 adult participants with a diagnosis of MS who consented to study enrolment on initiation of a DMT at the Queen Square MS Centre (National Hospital of Neurology and Neurosurgery, University College London Hospital NHS Trust, London) between 01/07/2019 and 31/07/2024. All patients were invited for clinical assessments, including the expanded disability status scale (EDSS) score, brief international cognitive assessment for MS and various patient-reported outcome measures (PROMs). They additionally underwent MRI at 3T, optical coherence tomography and blood tests (for genotyping and serum biomarkers quantification), at baseline (i.e., within 3 months from commencing a DMT), and between 6–12 (re-baseline), 18–24, 30–36, 42–48 and 54–60 months after DMT initiation.

Findings to date

748 participants provided baseline data. They were mostly female (68%) and White (75%) participants, with relapsing–remitting MS (94.3%), and with an average age of 40.8 (±10.9) years and a mean disease duration of 7.9 (±7.4) years since symptom onset. Despite low disability (median EDSS 2.0), cognitive impairment was observed in 40% of participants. Most patients (98.4%) had at least one comorbidity. At study entry, 59.2% were treatment naïve, and 83.2% initiated a high-efficacy DMT. Most patients (76.4%) were in either full- or part-time employment. PROMs indicated heterogeneous impairments in physical and mental health, with a greater psychological than physical impact and with low levels of fatigue. When baseline MRI scans were compared with previous scans (available in 668 (89%) patients; mean time since last scan 9±8 months), 26% and 8.5% of patients had at least one new brain or spinal cord lesion at study entry, respectively. Patients showed a median volume of brain lesions of 6.14 cm3, with significant variability among patients (CI 1.1 to 34.1). When brain tissue volumes z-scores were obtained using healthy subjects (N=113, (mean age 42.3 (± 11.8) years, 61.9% female)) from a local MRI database, patients showed a slight reduction in the volumes of the whole grey matter (–0.16 (–0.22 to –0.09)), driven by the deep grey matter (–0.47 (–0.55 to –0.40)), and of the whole white matter (–0.18 (–0.28 to –0.09)), but normal cortical grey matter volumes (0.10 (0.05 to 0.15)). The mean upper cervical spinal cord cross-sectional area (CSA), as measured from volumetric brain scans, was 62.3 (SD 7.5) mm2. When CSA z-scores were obtained from the same healthy subjects used for brain measures, patients showed a slight reduction in CSA (–0.15 (–0.24 to –0.10)).

Future plans

Modelling with both standard statistics and machine learning approaches is currently planned to predict individualised treatment response by integrating all the demographic, socioeconomic, clinical data with imaging, genetic and serum biomarkers. The long-term output of this research is a stratification tool that will guide the selection of DMTs in clinical practice on the basis of the individual prognostic profile. We will complete long-term follow-up data in 4 years (January 2029). The biobank and MRI repository will be used for collaborative research on the mechanisms of disability in MS.

Crowded housing, indoor environment and childrens respiratory, allergic and general health in Sweden: a cross-sectional study

Por: Eiffener · E. · Murekatete · R. · Merritt · A.-S. · Georgelis · A. · Fahlen Zelander · C. · Al-Nahar · L. · Jakobsson · K. · Albin · M. · Bergström · A. · Jonsson · M. · Eriksson · C. — Septiembre 24th 2025 at 03:32
Objectives

The aim of this study was to analyse associations between crowded housing and children’s indoor living environment, respiratory and allergic disorders and general health.

Design

A cross-sectional study.

Setting

Sweden, using data from the Swedish National Environmental Health Survey 2019.

Participants

The study sample included 48 512 children (aged 6–10 months, 4 years and 12 years). We also investigated associations in vulnerable subgroups, such as children with asthma and those living under unfavourable socioeconomic conditions.

Primary and secondary outcome measures

Primary outcomes in the living environment were at least one sign of mould, poor indoor air quality, unpleasant odours, too warm indoors in summer and too cold indoors in winter. Primary outcomes for children’s health were asthma, airway problems, breathing difficulties, rhinitis symptoms, mould and mites allergy, pollen allergy, furred pet allergy and good general health.

Results

About one in five children lived in an overcrowded home. Factors from the indoor living environment such as perceived poor indoor air quality and mould were significantly associated with crowded housing. Moreover, children who lived in overcrowded conditions were less likely to report good general health than children in non-crowded households (OR 0.64, 95% CI 0.54 to 0.76). This association was even stronger in children with asthma (OR 0.51, 95% CI 0.34 to 0.77). Few significant associations were, however, observed with the respiratory and allergic health outcomes.

Conclusions

Crowded housing is associated both with a poor indoor environment and with poorer general health in children. Children with asthma may experience even poorer general health.

Mesosystem of mental health services and support, its actors and their collaborations--a study protocol for an integrative review

Por: Törnqvist · T. · Rytterström · P. · Van Citters · A. · Rystedt · I. — Septiembre 24th 2025 at 03:32
Introduction

Psychiatric conditions require long-term maintenance, and people with mental illness are often involved in care provided by multiple service providers. At the same time, reports indicate that people with mental illness and comorbid physical health conditions often fail to get their needs met in current systems. For example, coordinated support within the mesosystem is rarely available, and mesosystem fragmentation often results in individual suffering as well as inefficient use of societal resources. Meanwhile, integrated services, where collaboration is important, have shown superior effectiveness compared with services and support delivered in parallel silos. This contradictory image needs further investigation, and there is a need for a better understanding of the dynamics and complexities of collaboration within the mesosystem.

Methods and analysis

This review aims to map the mesosystem for services and support for people with mental illnesses. The review will seek to answer questions such as who are the actors (formal and informal) in the mental health services and support mesosystem, and how are collaborations among actors organised and implemented? To synthesise qualitative, quantitative and mixed methods findings, it uses a systematic integrative methodology. Searches will be conducted in PubMed, PsycINFO, CINAHL and Web of Science between 17th June and 21st 2024. Data will be extracted and synthesised using Covidence software. Two blinded researchers will make determinations regarding the inclusion and exclusion of articles. The subsequent process of analysis will be jointly conducted by the whole research team. Preferred Reporting Items for Systematic Reviews and Meta-Analyses tools for quality assessments will be used.

Ethics and dissemination

Articles included in the review will be analysed through an ethical lens, making sure that ethical considerations have been made where applicable. The study will result in a scientific publication in a peer-reviewed journal.

Trial registration number

The study is registered in PROSPERO, no CRD42024543891.

Introduction

The only supportive therapy for patients with severe acute kidney injury (AKI), a common complication among the critically ill, is dialysis. Based on the literature and current guidelines, continuous renal replacement therapy (CRRT) with a total effluent dose of 20–25 mL/kg/hour and adjustments to ensure such dose is delivered despite down time (eg, due to surgical procedures) is recommended. However, experimental and clinical studies suggest that azotaemia, which can be induced by lowering the effluent dose, may accelerate renal recovery. This clinical study investigates whether a lower effluent dose (10–15 mL/kg/hour) for a maximum of 7 days or until successful (>24 hours) liberation of CRRT in critically ill patients with a dialysis-dependent AKI accelerates renal recovery and reduces time on CRRT compared with guideline-directed standard dose (25–30 mL/kg/hour).

Methods and analysis

The Ketzerei trial is an international, multicentre randomised, controlled trial, designed to investigate if a lower effluent dose (10–15 mL/kg/hour) accelerates renal recovery and reduces the time on CRRT compared with the guideline directed standard effluent dose (25–30 mL/kg/hour). The study aims to enrol 150 critically ill patients with a dialysis-dependent AKI. Eligible patients will be randomised to receive either a standard effluent dose (control group, 25–30 mL/kg/hour) or lower effluent dose (interventional group, 10–15 mL/kg/hour). The primary endpoint is the number of days free from CRRT and alive (from randomisation through day 28). Key secondary endpoints include the number of (serious) adverse events due to potential uremia, the duration of RRT and intensive care unit survival.

Ethics and dissemination

The Ketzerei trial has been approved by the Ethics Committee of the Chamber of Physicians Westfalen-Lippe (2023–343 f-s), the University of Muenster and subsequently by the corresponding Ethics Committee of the participating sites. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and will guide patient care and further research.

Stellate ganglion block for preventing postoperative arrhythmias: a protocol for a systematic review and meta-analysis

Por: Nunez-Rodriguez · E. · Mishima · R. · Martinez · F. · Aveni-Strafile · P. · Zheng · G. · Hicklen · R. S. · Tsai · E. · Cata · J. — Septiembre 23rd 2025 at 03:05
Introduction

Postoperative arrhythmias are common and clinically significant complications. They are a cause of increased morbidity and mortality rates in surgical patients. Although various pharmacological and procedural strategies have been explored for preventing postoperative arrhythmia, evidence regarding their effectiveness remains inconsistent. The stellate ganglion block (SGB) has emerged as a promising alternative to reduce the occurrence of postoperative arrhythmias. By summarising the existing evidence, this meta-analysis aims to assess the effectiveness of SGB in preventing postoperative arrhythmias.

Methods and analysis

We will review literature from January 1970 to April 2025 using MEDLINE, Cochrane CENTRAL and Embase. Studies eligible for inclusion will be randomised controlled trials and observational studies reporting postoperative arrhythmia incidence in surgical patients who received preoperative or intraoperative SGB. We will include articles in the following languages: English, Spanish, Chinese or Portuguese. Secondary outcomes are SGB-related complications. The risk of bias will be determined by Rob-2 and ROBINS-I tools. Meta-analyses, reporting relative risks or ORs with 95% confidence intervals will be performed when at least three studies report the same outcome under comparable conditions. Quality of evidence will be evaluated using GRADE guidelines.

Ethics and dissemination

We will use information from previously published manuscripts found in reputable databases, and ethical approval is not necessary.

Healthcare utilisation and barriers to healthcare after violence and rape in the Norwegian population: a cross-sectional, multimethod study

Por: Skauge · A. D. · Aakvaag · H. F. · Strom · I. F. · Nissen · A. · Seifert · L. C. · Överlien · C. · Dale · M. T. G. — Septiembre 23rd 2025 at 03:05
Objectives

Despite the important role of healthcare services in trauma recovery, many survivors of violence do not seek help. This study aims to examine rates of healthcare utilisation, including differences for physical violence versus rape, gender and physical injury (vs no injury) and obstacles to seeking care within 6 months following incidents of physical violence and rape.

Design and setting

The participants were randomly chosen from the National Population Registry in Norway and invited to participate in a telephone survey on violence exposure and health between June 2021 and June 2022 (N=4299, 49% women).

Participants

The sample included 1768 violence-exposed individuals. Of the women (n=749), 82.1% had experienced physical violence and 40.3% had experienced forcible rape. Of the men, most had experienced physical violence (98.6%) and a small percentage had experienced rape (3.5%).

Outcome measures

Logistic regression models were used to investigate whether healthcare seeking differed by gender, type of violence (rape vs physical violence) and severity (physical injury). Barriers to accessing healthcare were also investigated using descriptive statistics and content analysis.

Results

Healthcare seeking rates were low after rape (16.9%) and physical violence (24.2%), with somewhat higher rates among individuals experiencing both types of violence (39.9%). There were no statistically significant differences in the odds of healthcare utilisation between the three types of violence exposures when we controlled for gender, physical injury, violence characteristics and sociodemographic factors. Men were more likely than women to have sought healthcare (adjusted OR (aOR): 1.37, 95% CI: 1.02 to 1.85, p=0.042). Physical injury was strongly associated with greater healthcare utilisation (aOR: 6.39, 95% CI: 4.85 to 8.41, p

Conclusions

Few victims seek healthcare shortly after experiencing rape or physical violence. Quantitative and qualitative findings indicate that many seek healthcare exclusively for severe physical injury. These results emphasise the need to improve health services’ outreach to victims of violence, who are at heightened risk of mental health issues and chronic illnesses.

Effects of mental health interventions given at youth-friendly health services and integrated youth services: a systematic review protocol

Por: Andersen · M. · Lostelius · P. V. · Bring · A. · Ring · L. · Nystrand · C. · Olsson · E. M. G. — Septiembre 22nd 2025 at 03:00
Introduction

Although poor mental health among young people has been increasing in the past decades, many young people are reluctant to use traditional mental healthcare. To cater to the needs of young people, various youth-friendly treatment options have been developed. These include the youth-friendly health service (YFHS) standards put forth by the WHO in 2012 and the integrated youth services (IYS) for mental health developed in certain countries globally. However, no synthesis of the effect of these services on youth mental health has been conducted. The aim of the proposed study is to conduct a systematic review of the effect of mental health treatments conducted within YFHS and IYS clinics. The primary research question is what effect mental health interventions given at ‘youth-friendly’ clinics for treating mental health, such as IYS and YFHS, have on the mental health and quality of life (QoL) of young people?

Methods and analysis

A preliminary search for other reviews on the topic was conducted during the first half of 2024, after which a protocol of the present study was registered in PROSPERO. In May 2024, a search was carried out in the PubMed, PsycINFO, CINAHL and Web of Science databases, which gave references for 12 738 papers to be screened for inclusion in the review, and a follow-up search was carried out in April 2025, yielding a further 2182 references. For inclusion, studies must have participants between 12 and 25 years of age; interventions be given at clinics designed to be ‘youth-friendly’ or given at an IYS; control condition, if any, consisting of standard care or waiting list; outcomes must be mental health symptomology or QoL. To be included, studies must be published from 2012 and onwards. Screening of titles and abstracts in the initial search was carried out independently by two reviewers. Screening of studies found in the follow-up search and in the reference lists of included articles will be carried out in the same way. Data analysis of the initial search was conducted in the latter half of 2024, while final data analysis including the results from the follow-up search is ongoing. The Cochrane risk of bias assessment tools will be used to assess bias of included articles, and certainty of the evidence will be evaluated according to the GRADE methodology. A meta-analysis of the results will be performed if a sufficient amount of homogenous data is found; otherwise, a synthesis without meta-analysis will be conducted.

Ethics and dissemination

The proposed review may form a valuable synthesis of the state of the art of treatment options catering to young people. Investigating the effectiveness of YFHS or IYS in treating young people’s mental health may inform future directions for development and research. The present study does not need ethical approval, since only previously published, ethically approved data are used in the current study. The findings of the study will be disseminated through submissions to peer-reviewed journals and international conferences, as well as disseminated within the Swedish YFHS community.

Background

In deprived urban areas of South America, young people face heightened risks of mental disorders. Research suggests an association exists between social media engagement (SME), depression and anxiety.

Objective

This study explored the associations of SME with symptoms of depression, anxiety and subjective quality of life among young people from South American deprived urban areas.

Methods

Our cross-sectional survey study used an adapted version of the Multidimensional Facebook Intensity Scale to categorise 2399 participants into four SME groups: low, moderate, high and very high. Symptoms of depression (Patient Health Questionnaire-8), anxiety (Generalised Anxiety Disorder-7) and quality of life (Manchester Short Assessment) were assessed and compared using F and Tukey tests.

Findings

Each step of increased SME was associated with more symptoms of depression and anxiety and poorer quality of life. Statistically significant differences were observed across all groups (p

Conclusions

The findings suggest an association exists between SME, increased mental distress and lower quality of life in young people from deprived South American urban areas. This influence seems to apply across the spectrum of engagement levels, not only to extremes. However, due to the cross-sectional nature of the study, causal relationships cannot be established.

Implications

SME should be explored in clinical settings, as lower levels are associated with lower symptom levels and better quality of life. Policies addressing youth SME should be developed and evaluated in the challenging contexts of deprived urban areas.

Bringing diagnostic home: models, challenges and enablers of home-based examinations imaging/graph services - a scoping review

Por: Costa · G. F. · Lorenzi · L. J. · Raymundo · T. M. · Kort · H. · Castro · P. C. — Septiembre 18th 2025 at 03:51
Background

Mobile diagnostic imaging services provided at home increase accessibility and convenience, particularly for older adults, people with disabilities and other vulnerable groups. These services can reduce the need for patient travel and support the routine monitoring of chronic conditions. However, current guidelines often overlook user acceptance and environmental considerations within the home setting.

Objectives

To map studies that identify the models, barriers and facilitators for performing home-based diagnostic imaging/graph according to end users.

Design

A scoping review was conducted following the methodological framework of the Joanna Briggs Institute and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist.

Eligibility criteria

Studies that addressed mobile or portable diagnostic imaging or graph examinations conducted in the home for individuals of any age or health status were included. Studies were eligible if they reported on barriers, facilitators or user experiences. Studies that focused on wearable technologies were excluded.

Sources of evidence

The search strategy was developed using terms related to home-based diagnostic imaging/graph, portability, home setting and user perceptions. Searches were conducted in PubMed, Web of Science, Scopus, Embase, The ACM Guide to Computing Literature and LILACS, without restrictions on publication date or language. Additional grey literature was identified through Google Scholar.

Data extraction and synthesis

Two reviewers independently extracted data using a standardised form that captured study characteristics, types of procedures, target populations and reported barriers and facilitators. Quantitative data were summarised using absolute and relative frequencies. Qualitative findings were synthesised through basic content analysis to identify and categorise recurring themes.

Charting methods

Data were charted in tables to organise and visually map study contexts, methodological features and thematic patterns related to implementation and user experience.

Results

Twenty-six studies published between 1998 and 2023 across 15 countries were included. The diagnostic examinations included mostly polysomnography, X-ray imaging and ultrasonography. Seven categories of barriers were identified, such as physical discomfort, equipment-related challenges and procedural limitations. Seven facilitators were also reported, including perceived comfort, patient satisfaction and equipment usability.

Conclusions

This review identifies key factors affecting the delivery and user experience of mobile diagnostic imaging at home, including logistical, technical and environmental aspects. It reveals gaps in the literature and provides a basis for future research to inform more inclusive and effective public health policies and service design.

Retrospective, nationwide cohort study.

Setting

Swedish Coronary Angiography and Angioplasty Registry, between June 2015 and December 2021.

Participants

24 284 patients with angiographically confirmed CTO. Prior coronary artery bypass graft surgery excluded. Subgroups were defined by DM status and BMI categories (underweight, healthy weight, overweight, obesity).

Primary outcome measures

Long-term all-cause mortality, assessed by Kaplan-Meier analysis and multivariable Cox proportional hazards regression.

Results

DM was present in 30.3% of patients and conferred a 31% higher risk of mortality (HR: 1.31, 95% CI: 1.20 to 1.42; p2, lowest risk (nadir) at 32 kg/m2 and modest rise above 35 kg/m2.

Conclusions

In this nationwide CTO cohort, DM independently predicted higher long-term mortality, accompanied by more severe comorbidities and greater CTO complexity, and insulin therapy further elevated hazard. Overweight and obese patients had better survival, while underweight individuals had the poorest prognosis. These findings underscore the importance of individualised risk assessment and management strategies in CTO patients, particularly those with DM or low BMI.

Tirzepatide for the treatment of adults living with concurrent type 1 diabetes and overweight or obesity (TZP-T1D): a double-blind, placebo-matched randomised controlled trial protocol

Por: Purcell · A. R. · Rodrigo · N. · Longfield · M. S. G. · Glastras · S. J. — Septiembre 17th 2025 at 06:57
Introduction

The increasing prevalence of overweight and obesity among individuals with type 1 diabetes (T1D) complicates glycaemic management and escalates insulin resistance, necessitating innovative therapeutic strategies. Tirzepatide, a dual agonist for glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptors, shows promise in managing weight and glycaemic control in type 2 diabetes but is unexplored in the context of T1D. This double-blind, placebo-controlled randomised trial will evaluate the efficacy of tirzepatide in adults with T1D and overweight/obesity over 32 weeks.

Methods and analysis

60 participants (aged 18–70 years) with a body mass index ≥27 kg/m2 and HbA1c≤10% will be randomised 1:1 to receive either tirzepatide or a placebo, alongside standard insulin therapy. The primary outcome is the change in body weight (%). Secondary measures include change in HbA1c (%), proportion of body weight lost (>5%, >10%, >15% and >20%), changes in insulin dosage, time in range by continuous glucose monitoring (CGM) criteria and severity of comorbidities. Compliance, adverse events and medication interactions will be closely monitored, with adjustments made for tolerability. Patient-reported outcomes and experiences will be measured to capture the benefits of glycaemic management, weight management and quality of life. To compare the means of body weight reduction (%) between the tirzepatide and control groups, an independent samples t-test will be employed under the assumption that data are normally distributed. Secondary outcome measures will be analysed by Student’s t-test. All data will be reported as group means with confidence intervals, with default statistical significance assumed at p

Por: Holm · K. G. · Hägi-Pedersen · M.-B. · Haslund-Thomsen · H. · Nilsson · I. · Aagaard · H. · Maastrup · R. · Ejlertsen · C. · Petersen · M. · Feenstra · M. M. · Kristensen · I. · Brodsgaard · A. — Septiembre 16th 2025 at 03:21
Introduction

Fathers of preterm infants wish to be actively involved and attentive in caring for their children. The positive impacts of paternal caregiving on preterm infants’ cognitive and social development have been recognised. Awareness of the need to support fathers during early parenthood is increasing, but fathers may feel excluded when their infants are in the neonatal intensive care unit. Here, we present the protocol for a study involving the development and national implementation of a complex intervention supporting first-time fathers of preterm infants in early parenthood.

Methods and analysis

The study adheres to the Medical Research Council framework for complex interventions. A multicentre, prospective, non-blinded, quasi-experimental design will be applied to evaluate the effect of a clinical and technology-based intervention targeting both nurses and the fathers. Outcomes from participants enrolled during the control (2023–2024) and intervention (2025–2026) periods, comprising 295 fathers and their partners, will be compared. Effects on parental confidence, stress, depression and mood and family and reflective functioning as well as infants’ emotional and social development will be assessed. A comprehensive process evaluation will be applied using both qualitative and quantitative methods.

Ethics and dissemination

The study has been registered at Clinicaltrials.org [no. NCT0 6 116 747 (The SUPPORTED study – First-time Fathers of Preterm Infants), approved on 3 November 2023]. The Danish Data Protection Agency has approved the study (P-2022–792). The findings will be disseminated through peer-reviewed publications.

Assessing tuberculosis infection prevalence and test concordance in high-risk groups: a cross-sectional study in Mexicali, Baja California

Por: Brumwell · A. · Herrera · R. · Contreras · K. · Lee · M. · Becerra · E. · Estrada-Guzman · J. · Nicholson · T. · Machado Contreras · R. · Brooks · M. B. — Septiembre 15th 2025 at 05:56
Background

Despite low sensitivity and implementation challenges, the tuberculin skin test (TST) remains the standard-of-care tuberculosis (TB) infection test in Mexico. Interferon gamma release assays (IGRA) may overcome TST-related challenges. Within the confines of the local programmatic setting, this cross-sectional study evaluated the prevalence of TB infection (TBI) and concordance of TST and IGRA in three high-risk populations in Mexicali, Baja California, Mexico.

Methods

Household contacts (HHC) of individuals with TB, people who use drugs (PWUD), people deprived of liberty (PDL) and prison employees underwent evaluation for TBI using TST and QIAreach, a novel IGRA. Prevalence of infection, concordance of test results and reactivity trends of time-to-results (TTR) by TST-induration size were assessed.

Results

In total, 214 of 411 (52.07%) people who had TST and 269 of 460 (58.48%) people who had IGRA tested positive for TBI. Frequency of infection varied across risk groups (HHC 29 (29.6%); PWUD 67 (70.53%); PDL 111 (56.06%) and prison employees 7 (35.0%), p20 mm, p=0.05).

Conclusion

All risk groups had a high frequency of TBI, necessitating locally tailored guidelines for screening, treatment and management of TBI to optimise care for vulnerable populations.

Effect on healthcare professionals self-efficacy of a 45-min versus 3-hour educational intervention on communication and play in paediatric clinical practice in Denmark: a randomised controlled trial study protocol

Por: Thestrup · J. · Sorensen · J. L. · Bidstrup · P. E. · Rosthoj · S. · Hybschmann · J. · Esbjorn · B. H. · Dybdal · D. · Barslund · K. · Topperzer · M. K. · Frandsen · T. L. · Gjaerde · L. K. — Septiembre 15th 2025 at 05:56
Introduction

Communication is a professional competence that all paediatric healthcare professionals must learn and maintain to provide age and developmentally appropriate care. Child-centred communication encourages direct communication with children and adolescents, incorporating the use of play as a communicative strategy. Still, many paediatric healthcare professionals receive little or no formal training in communication and play. A critical barrier to communication training is the limited possibilities for healthcare professionals to take time from their clinical duties. Moreover, few randomised controlled trials have evaluated educational programmes on communication and play for paediatric healthcare professionals, and existing programmes vary significantly in design and duration. This study aims to compare the effects of a 45-min and a 3-hour educational intervention for healthcare professionals on age-appropriate communication and the use of play in clinical paediatric practice.

Methods and analysis

We will describe a single-centre, randomised, controlled, two-arm, non-inferiority trial. We will recruit 150 healthcare professionals with different professional backgrounds who will be randomised to one of two arms: a 45-min or 3-hour educational intervention on communication and play in paediatric clinical practice. The primary outcome will be their self-efficacy in patient-centredness at 12-week post-intervention, while secondary outcomes will be self-efficacy immediately after the intervention, motivation to engage in the educational activity, cognitive load, self-evaluated knowledge, satisfaction and the impact on individual practice and training needs. Data will be collected through questionnaires at baseline, immediately after the intervention, and 12 weeks post-intervention and will be analysed using linear mixed models with random effects to account for clustering and within-subject correlation.

Ethics and dissemination

The Danish Data Protection Agency approved the study (P-2020–1144), which will be conducted in accordance with the Declaration of Helsinki. Findings will be published in a peer-reviewed open-access scientific journal and presented at international conferences.

Ages of sitting and walking milestone attainment in typically developing children worldwide: protocol for a scoping review

Por: Wickstrom · J. · Choudhry · I. · Leone · E. J. · Piergies · A. M. H. · Das · T. · Chenowith · A. · Hehn · A. · Friedman · E. B. · Livinski · A. A. · Silfen · K. · Shad · A. · Iverson · J. M. · Thurm · A. — Septiembre 12th 2025 at 05:14
Introduction

Ages of attainment for early gross motor milestones have been widely studied, but definitions and measurement methods have varied greatly. Since delays in motor milestones have been used extensively as one of the earliest indicators of atypical development, it is imperative to establish a universal understanding of the methods and results reported on motor milestones in typically developing children. Therefore, the primary aim of this scoping review is to provide an overview of recent studies reporting ages of onset for independent sitting and walking in typically developing children worldwide; this will be achieved by summarising how these milestones have been operationalised and evaluated, the samples from whom these data have been drawn, and the reported ages of acquisition.

Methods and analysis

To meet inclusion criteria, articles must: be original research papers published in any language since 2003, contain a sample of typically developing children and report actual ages of onset for independent sitting and/or walking. To conduct this scoping review, the Joanna Briggs Institute methodological framework will be used. Search terms will include variations of the following concepts: acquisition of motor milestone (independent sitting and/or walking), age of onset, infancy. Six databases (CINAHL Plus, Embase, PsycNet: PsycINFO & PsycArticles, PubMed, Scopus, Web of Science: Core Collection) will be searched. Records from these databases will be screened for eligibility. Two people will independently review each record during title and abstract screening, and three people will independently screen full texts and extract data. Results will be displayed in tables, graphs and narrative summaries in the scoping review.

Ethics and dissemination

As the review will only include previously published data, ethics approval is not required. Findings will be shared at scientific conferences and in a peer-reviewed journal.

Introduction

In the UK, approximately 5.4 million adults live with asthma, of whom one in five have an uncontrolled form. Uncontrolled asthma reduces quality of life and increases healthcare use. Engaging with peers through online health communities (OHCs) can empower patients to self-manage their long-term condition. While OHCs have been in existence for several years and growing numbers of patients access them, the role of primary care in signposting patients to them has been minimal and ad hoc. We have co-developed with patients and healthcare professionals (HCPs) an intervention for adult patients with asthma, consisting of an appointment with a primary care HCP to introduce online peer support and sign patients up to an established asthma OHC, followed by OHC engagement. Feasibility work found the intervention acceptable to patients and HCPs. This protocol outlines our plan to test the intervention’s effectiveness and cost-effectiveness.

Methods and analysis

An individual randomised controlled trial will be carried out. Eligible participants will be recruited via an online survey sent to adult patients on the asthma register in 50–70 general practices in several UK locations. Participants will be invited to attend a one-off, face-to-face appointment with a primary care HCP, during which they will be individually randomised to the intervention or usual care. An asthma control test (primary outcome) and other measures of clinical effectiveness will be collected at baseline and every 3 months over a 12-month follow-up period. Descriptive and inferential statistics will be used to compare outcome measures between study arms. Cost-effectiveness assessment of the intervention compared with current standard of asthma management in primary care will be reported. A sample of patients and HCPs will be interviewed at study exit and the data analysed thematically.

Ethics and dissemination

The study was approved by a National Health Service Research Ethics Committee (reference: 25/NE/0006). Written consent will be obtained from all participants. Findings will be disseminated through various means, including sharing with general practices, conference presentations and peer-reviewed publications.

Trial registration number

NCT06849245.
