Chiliadenus montanus (Vahl) Boiss. (Asteraceae) is a pharmacologically significant plant with different potent pharmacological properties. This study aimed to evaluate the phytochemical and anticancer activity of C. montanus, and to develop nanoemulsions (NEs) to enhance pulmonary delivery for lung carcinoma treatment. For that ethanol and water extracts, along with petroleum ether, chloroform, ethyl acetate, and methanol fractions, were assessed for total phenol and flavonoid contents, antioxidant activity, and cytotoxicity against H1299 and A549 lung cancer cell lines. The results showed that ethyl acetate fraction exhibited the highest phenol (47.94 ± 0.32 mg GAE/g of DW) and flavonoid (20.34 ± 1.48 mg rutin/g of DW) contents, while the ethanol extract showed the most potent antioxidant activity (IC₅₀ = 322.1 µg/mL) and selective cytotoxicity (IC₅₀ = 641.2 µg/mL) against H1299 cells. Nevadensin, chlorogenic acid, and sorbifolin were identified as the major constituents of the ethanol extract using liquid chromatography-mass spectrometry (LC-MS) analysis. Gas chromatography-mass spectrometry (GC-MS) analysis revealed α-phellandrene, 1,8-cineole, and α-cadinol as the lead volatile constituents. The major volatile compound of the aroma profile of the aerial parts, determined by solid phase micro extraction (SPME) was 1,8-cineole. Spontaneous emulsification was used to formulate ethanolic NE (S1-S4 NEs) with varying concentrations of ethanol extract, surfactant, cosurfactant, and oil phase. The optimal S4 NE demonstrated thermodynamic stability, appropriate pulmonary pH, and droplet sizes below 100 nm. These findings highlight the promising potential of C. montanus NE as a stable pulmonary drug delivery system for lung carcinoma therapy.Over the past two decades, initiatives promoting research-policy engagement have increased broadly and in health. Numerous factors influencing the engagement of policymakers in research have been described primarily from the perspective of researchers. This scoping review aimed to identify the enablers and barriers to policymaker engagement across the research process from the perspective of policymakers.

We included English language studies published after 2007 that involved policymakers at national or subnational levels who were actively engaged in research at any stage. We excluded studies which did not include policymakers, where engagement was passive, or perspectives were marginal or not clearly outlined.
After screening and full-text review, we extracted and coded data using MAXQDA Plus 24. We conducted thematic analysis, categorising findings as enablers or barriers into three levels: individual, organisational and contextual/system. Findings were iteratively reviewed and refined by the research team.
We screened 5384 titles and abstracts, reviewed 59 full-text documents and included 30 articles for analysis. Most studies were published after 2016 and were focused on policymaker engagement at the national level. Organisational factors were the most frequently reported influences on engagement of policymakers in research across different contexts. The most frequent enablers mentioned in the literature were (1) the institutionalisation of partnerships, initiatives and having formal agreements; (2) defining goals, roles, responsibilities and conflict resolution mechanisms; (3) researchers providing practical and expert advice to policymakers; (4) leveraging networks; and (5) having supportive institutions. The most frequent barriers were (1) the lack of regulations, infrastructure, funding and communication channels to support engagement; (2) the lack of skills of researchers to understand policymaking processes and work in collaboration with policymakers; and (3) the mismatch in priorities, values, perspectives and expectations.
Our study highlights the role of institutional support, widespread collaboration opportunities and the interconnected nature of these factors within the research-policy ecosystem.

To examine the impact of the COVID-19 pandemic on the substitution of surgical procedures in benign gynaecology in the Netherlands.
Quantitative longitudinal study evaluating the effects of the COVID-19 pandemic.
Nationwide healthcare delivery was analysed across six benign gynaecological pathways from 2016 to 2022 using Vektis and Dutch Hospital Data (DHD), accessed via Statistics Netherlands (Centraal Bureau voor de Statistiek).
The study focused on six benign gynaecological pathways classified using Dutch Diagnosis Treatment Combinations (DTCs): heavy menstrual blood loss (G11), uterine fibroids (G15), endometriosis (G17), prolapse (G25), infertility treatment (F11) and first trimester pregnancy complications (Z12). All patients receiving care within these pathways between 1 January 2016 and 31 December 2022 were included. Exclusions applied to all patients under 18 years old and, only within the menstrual disorder pathway, patients over 51 years old to exclude most postmenopausal blood loss cases where no alternative treatment applies.
Cohorts from the initial pandemic year (2020) were compared with four prepandemic cohorts (2016–2019) and late-pandemic (2021) and postpandemic (2022) cohorts.
The primary outcome was the trend in the total number of patients in surgical and non-surgical procedure groups across cohort periods. Secondary outcomes included trends within individual pathways.
The analysis identified a significant reduction in benign gynaecological care during 2020, with an 18.3% (p
The COVID-19 pandemic significantly disrupted both surgical and non-surgical procedures within benign gynaecological pathways. Reduced care uptake during the pandemic waves was not recovered but instead forgone. The reduction in surgical procedures did not correspond with increased use of non-surgical alternatives. Future research should prioritise evaluating the long-term impacts of this disruption on patients and society.
Novel diagnostics, particularly point-of-care (POC) tests, play a crucial role in the early detection and management of infectious diseases, especially in resource-limited settings. Ensuring test performance and quality while minimising the risk of human error becomes more relevant when shifting testing tasks from highly controlled settings like centralised laboratories to people with minimal training. Applying usability and human factors engineering principles can reduce the challenges related to human errors. Despite existing frameworks and tools, the practical application of usability guidelines remains variable across different settings.
This scoping review protocol outlines a systematic investigation of current practices in assessing the usability of novel diagnostics, particularly POC tests for infectious diseases intended for use in low-income and middle-income countries. The review will analyse original research studies of all designs and product dossiers that report on the usability evaluation or validation of a diagnostic test for an infectious disease. A qualitative synthesis of the data extracted from the articles will be conducted. We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols and the Joanna Briggs Institute guidelines for this scoping review.
No ethical approval is required because individual patient data will not be included. The findings will be disseminated through publication in a peer-reviewed journal.
Knee osteoarthritis (OA) is a serious public health problem since it is linked to loss of muscular function and independence, especially in older adults. In this study, the researchers have proposed a randomised controlled trial with a three-arm study strategy to explore the effectiveness of an oral nutritional supplementation containing hydroxymethylbutyrate and undenatured type-II collagen combined with exercise training (ET) on the OA-related symptoms and biomarkers among adults with knee OA.
Adults with knee OA aged between 50 years and 75 years will be invited to participate in the study and thereafter will be randomly assigned to either one of three groups: oral nutrition supplementation+ET, ET or usual care. The primary outcomes include changes in OA-related symptoms and biomarkers. The secondary outcomes include changes in body composition, blood profiles, physical fitness, quality of life, dietary intake, disability, psychology status and morphological changes of the knee.
Ethics approval was granted by the Medical Research Ethics Committee of the National University of Malaysia (reference number JEP-2024–264). Findings of this study will be disseminated via peer-reviewed presentations at scientific conferences as well as open access publications.
The use of e-health interventions has grown in demand due to their accessibility, low implementation costs and their potential to improve the health and well-being of people across a large geographical area. Despite these potential benefits, little is known about the cost-effectiveness of self-guided e-health interventions. The aim of the study was to compare the cost and consequences of ‘iSupport’, an e-health intervention to reduce mental health issues in dementia carers.
A cost-consequence analysis (CCA) of a multi-centre, single-blind randomised controlled trial of iSupport. The CCA was conducted from a public sector (National Health Service, social care and local authority) perspective plus a wider societal perspective. Delivery costs of iSupport were collected using a bottom-up micro-costing approach.
352 participants were recruited from three centres in England, Wales and Scotland.
Participants eligible for inclusion were adults over the age of 18 years who self-identified as an unpaid carer with at least 6 months of experience caring for an individual with a diagnosis of dementia. Between 12 November 2021 and 31 March 2023, 2332 carers were invited to take part in the study. 352 participants were randomised: 175 randomised to the iSupport intervention group and 177 to the usual care control group. The mean age of participants in the intervention and control groups was 63 and 62, respectively.
The CCA presented the disaggregated costs and health-related quality of life measured using the EuroQol five-dimension.
There was no significant difference in generic health-related quality of life measured using the EQ-5D-5L (p=0.67). Both groups reported higher mean costs between baseline and 6 months, but the change in costs was significantly lower in the intervention group. Between baseline and 6 months, the mean change in total resource use costs from the public sector perspective was significantly different between groups (p=0.003, r=–0.161) reporting a mean change per participant of £146 (95% CI: –33 to 342) between the intervention and control groups. From the wider societal perspective, there was no significant difference (p=0.23) in the mean change in total resource use and informal care costs between the two groups from baseline to 6 months.
Use of iSupport was associated with reduced health and social care resource use costs for carers compared with care-as-usual. Self-guided e-health interventions for dementia carers may have the potential to reduce health and social care resource use and wider societal costs, but evidence relating to their effectiveness and cost-effectiveness is lacking.
To (1) synthesise the experiences of people with heart failure and those who care for them concerning participation in physical activity (2) develop a logic model for a future intervention which will support people with heart failure to feel confident and safe in being physically active.
A systematic review and meta-aggregation using Joanna Briggs Institute (JBI) methodology.
MEDLINE, Emcare and PsycINFO databases were searched through until June 2024 inclusively.
Studies with a qualitative design, including qualitative components of mixed-methods studies, which describe experiences of participation in physical activity by adults with chronic heart failure.
Two independent reviewers used standardised methods to search and screen studies. Data extraction included the PROGRESS-Plus items. The JBI checklist for qualitative studies was applied. Meta-aggregation guided by JBI methods was used to synthesise the data. This evidence, along with input from a patient and public involvement group, healthcare professionals and charity organisations, was used to develop a logic model.
We included 28 papers (25 studies) comprising 14 qualitative studies and 11 mixed-method studies describing the perspectives of 483 people with heart failure, 64 carers and 12 healthcare professionals.
The meta-aggregation produced seven synthesised findings describing the impact of physical symptoms, emotional factors, extrinsic factors, access to knowledge, self-motivation and peer/professional motivation and the positive impact of physical activity. The PROGRESS-PLUS tool identified significant inclusivity issues within the studies. The meta-aggregation with relevant contributor input informed behavioural determinants and potential intervention components of a logic model.
This study identifies behavioural determinants that underlie the actions of people with heart failure in their relationship with physical activity and potential intervention components for a novel intervention design to support this population. There is a lack of studies exploring health professionals’ and carers’ perspectives on this topic.

To measure the reliability of pH testing to confirm ongoing nasogastric tube (NGT) position and to document associated complications.
Confirming NGT position is essential, as use of an incorrectly positioned tube can cause harm. Substantial evidence examines initial confirmation of NGT position, yet limited evidence exists considers NGT displacement which is identified via ongoing NGT position tests. In the NHS, pH testing is recommended to confirm ongoing NGT position; however, there may be an association with excess X-rays and missed enteral nutrition and/or medications.
Prospective observational study using STROBE checklist.
Data collected from medical records of 136 patients with NGTs in a London NHS Trust included pH tests, test results and complications related to ongoing pH tests which failed to confirm the tube was positioned in the stomach, that is, X-rays, and disruptions to enteral nutrition and medication. Cohen's Kappa determined pH test reliability.
Of 1381 pH tests conducted to confirm NGT position, five (0.3%) correctly identified an NGT displacement, and one (0.07%) failed to identify displacement before use. The reliability of ongoing pH tests using Cohen's Kappa was minimal (0.29). Ongoing pH tests that failed to confirm a correctly positioned NGT led to 31 (22.8%) patients having X-rays, 24 (17.6%) missing >10% of prescribed enteral nutrition and 25 (18.4%) missing a critical medication.
Ongoing NGT position testing using pH tests did not prevent the use of a displaced tube, and more than one-fifth of patients required X-rays to confirm a correctly position NGT, contributing to missed medications and enteral nutrition.
Caution should be used when confirming ongoing NGT position with a pH test. Future guidelines should balance the risk of using a displaced tube with potential delays to nutrition and/or medication. More research is needed to explore alternative methods of ongoing NGT position testing.
Topical keloid therapy is performed with triamcinolone acetonide (TA) intralesional injection. However, the recurrence rate is high with various side effects. Mesenchymal stem cells (MSCs) have high proliferative abilities and reduce the activity and proliferation of fibroblast cells in keloids. To overcome the costs and limitations, conditioned medium (CM) is used. This study aims to evaluate feasibility of intralesional injection of umbilical cord MSC (UC-MSC) and conditioned medium (UC-CM) compared to TA for keloid therapy. Twenty-four patients with keloids who met the inclusion criteria were included, randomized into three treatment groups and then got assessed for the sociodemographic data, keloid volume, histopathology (type 1:3 collagen ratio), interleukin-10 (IL-10) levels and Patient and Observer Scar Assessment Scale (POSAS) score during visits. Largest volume regression occurred in the UC-MSC group, followed by UC-CM and then the TA group (UC-MSC: 45.32% ± 2.61%; UC-CM: 43.61% ± 3.67%; TA: 28.34% ± 3.81%; p = 0.003). Similar pattern was also observed in increase in IL-10 levels, the decrease in POSAS scores and the reduction of type 1:3 collagen ratio. Hence, UC-MSC and UC-CM are promisingly more effective than TA for keloid therapy, showcasing their superiority in reducing keloid volume, symptoms and type 1:3 collagen ratio, as well as increasing the levels of IL-10.
