Anti-hepatocellular carcinoma activity of <i>Jacaranda mimosifolia</i> through experimental validation and network pharmacology

by Ayesha Bibi, Muhammad Hamza Afandi, Azra Mehmood, Usman Ali Ashfaq, Muhammad Shareef Masoud, Mohsin Ahmad Khan, Rashid Bhatti

Hepatocellular carcinoma (HCC) has a very significant mortality rate and is one of the most common cancers worldwide. Jacaranda mimosifolia is reported to have potential antitumor activities against various human cancers. However, the effects of J. mimosifolia on HCC are yet elusive. This study aimed to investigate the anti-HCC potential of methanolic extract of J. mimosifolia leaves using in vitro and in vivo studies and a network pharmacology approach. The effect of J. mimosifolia extract was assessed on Huh-7.5 cells using MTT assay, wound healing assay, and DNA fragmentation assay. These experiments found that J. mimosifolia extract significantly suppressed Huh-7.5 cell proliferation, impaired cell migration, and induced cell apoptosis. The real-time PCR validated the upregulation of p53 and Bax, alongside the downregulation of AFP and GPC3 in Huh-7.5 cells after treatment with J. mimosifolia extract. In vivo experiments confirmed the hepatoprotective effects of J. mimosifolia extract in mice models with CCl4-induced hepatic injury. In addition, through network pharmacological analysis, J. mimosifolia was found to play a critical role against HCC via targeting multiple potential targets and pathways. Docking analysis identified apigenin and kaempferol with the lowest binding energy against PTGS2 and EGFR, respectively, while flavonol glycoside showed the lowest binding energy against MMP9. However, detailed research is needed to isolate the potential phytochemicals from J. mimosifolia against HCC.

Objectives

This study aimed to quantify how patient risk factors relate to COVID-19 severity across categories 1–5 in a prospective, hospital-based cohort. We hypothesised that greater severity would be associated with higher odds of intensive care unit (ICU) admission and in-hospital mortality. Secondary aims were to assess associations with age, viral variants, symptom clusters, lymphocyte count, fasting blood glucose and cytokine profiles.

Design

Prospective cohort study.

Setting

A secondary-care/tertiary-care hospital and linked community settings in Cheras, Kuala Lumpur, Malaysia.

Participants

This study was nested within the COVGEN project, a prospective COVID-19 cohort conducted at Hospital Canselor Tuanku Muhriz UKM (HCTM), Cheras Health Clinic and the Bandar Tun Razak COVID-19 Assessment Centre in Cheras, Kuala Lumpur, Malaysia, from 1 August 2021 to 31 October 2022. 2532 participants were enrolled at baseline. Eligible participants were Malaysian citizens aged 12–18 years (paediatric/adolescent) or ≥18 years who had reverse transcription-polymerase chain reaction–confirmed COVID-19 at recruitment and resided in Kuala Lumpur or Selangor. Patients who had a clinically unstable condition and those who declined participation (personally or via a next-of-kin or legal representative) were excluded. This analysis included 559 patients hospitalised at HCTM; after excluding five with incomplete questionnaires, 554 remained for analysis (413 admitted to general wards and 141 to ICUs). Categories 3–5 comprised hospitalised patients, whereas categories 1–2 included hospitalised individuals and a subset recruited from community settings.

Primary and secondary outcome measures

Primary outcomes included disease severity (categories 4–5 vs 1–3), ICU admission and in-hospital mortality. Secondary outcomes included associations with age strata, viral variant (delta vs omicron), symptom clusters, lymphocyte count, fasting blood glucose and cytokines: interferon gamma-inducible protein 10, interferon gamma, interleukins 8, 10, 2, 6 and 7 and tumour necrosis factor alpha.

Results

141 of 554 (25.5%) patients required ICU care. Compared with milder categories, category 5 was associated with markedly higher odds of ICU admission (OR 204.50; 95% CI 37.54 to 1114.18; p55 versus

Conclusions

An increasing clinical severity category was strongly associated with ICU admission and mortality. Age, delta infection, specific symptom clusters, lymphopenia, hyperglycaemia and pro-inflammatory cytokines identified higher-risk patients, supporting risk-stratified management and prioritisation for enhanced monitoring.

Objective

To assess cardiovascular health (CVH) metrics using the American Heart Association’s Life’s Simple 7 (LS7) tool as a comprehensive measure of several metabolic and behavioural risk factors for cardiovascular diseases.

Design

Cross-sectional study, nationally representative Iran STEPwise approach to non-communicable diseases risk factor surveillance (STEPS) survey 2021.

Setting

Iran, 2020–2021.

Participants

25 202 adult individuals aged 25 years and older participated in the STEPS survey.

Outcome measures

Using the LS7 framework, seven factors were assessed: current smoking, body mass index (BMI), physical activity level, modified healthy diet score components, total cholesterol, blood pressure and fasting plasma glucose (FPG). Each factor was categorised into three levels of poor, intermediate and ideal, according to the LS7 methodology.

Results

The study participants had a sex distribution of 55.5% females. The findings revealed a high prevalence of ideal levels of smoking (80.1%; 95% CI 79.3 to 81.0), total cholesterol (69.4%; 95% CI 68.5 to 70.4) and FPG (61.0%; 95% CI 60.0 to 62.1). BMI and blood pressure were ideal in about one-third of the population (33.0%; 95% CI 32.1 to 34.0, and 30.5%; 95% CI 29.6 to 31.4, respectively). However, only 13.3% (95% CI 12.6 to 14.0) of participants achieved ideal levels of physical activity, and a mere 0.4% (95% CI 0.3 to 0.6) adhered to an ideal healthy diet. Modest disparities in CVH metrics were observed across provinces and between two sexes. Ideal CVH status was significantly associated with lower risks of major diseases such as ischaemic heart disease, diabetes and chronic kidney disease.

Conclusions

Despite favourable scores in some CVH metrics, critical gaps in diet and physical activity highlight the need for intensive public health efforts to enhance CVH in Iran. The study emphasises the urgency of implementing region- and sex-specific public health policies.

Proton Nuclear Magnetic Resonance With Time‐Frequency Analysis: A Potential Diagnostic Approach for Keloids

ABSTRACT

Keloids are chronic fibroproliferative skin disorders with high recurrence rates and limited treatment options, yet reliable diagnostic biomarkers are lacking. Current classification systems rely heavily on clinical observation, underscoring the need for objective, noninvasive tools. In this exploratory study, serum-based 1H nuclear magnetic resonance (NMR) measurement combined with short-time Fourier transform (STFT) for time-frequency analysis was performed, followed by principal component analysis (PCA), to investigate potential patient subgroups. Serum samples from 29 patients were analysed and PC1 scores suggested two potential patient subgroups. Retrospective analysis showed that these subgroups differed primarily in keloid aetiology: one group predominantly included cases arising from unclear or minimal causes (e.g., acne, folliculitis), whereas the other comprised cases following clear traumatic events (e.g., surgery). Although most clinical variables showed no significant differences, significant differences in aetiology and Japan Scar Workshop Scar Scale (JSS) scores support the biological relevance of this separation of subgroups. These findings suggest that the time-frequency features of NMR signals from serum samples capture systemic characteristics associated with keloid pathophysiology. If validated in larger cohorts, this approach may serve as a noninvasive adjunct to clinical assessment and lay the foundation for objective patient stratification and precision-guided treatment strategies.

Impact of postoperative macular comorbidity on visual outcomes after Descemet’s membrane endothelial keratoplasty: A multicenter analysis

by Naoya Nakagawa, Ami Igarashi, Hideaki Yokogawa, Akira Kobayashi, Tomomi Higashide, Satoru Yamagami, Takahiko Hayashi

The aim of this study was to identify the clinical factors associated with postoperative visual acuity following Descemet’s membrane endothelial keratoplasty (DMEK), with emphasis on the impact of macular diseases. This retrospective multicenter study included consecutive eyes that underwent DMEK between March 1, 2011, and June 30, 2022, and had available optical coherence tomography findings. Eyes with other ocular diseases causing visual loss were excluded. Overall, 77 eyes of 66 patients were included in the study. Univariable and multivariable regression analyses were performed to identify the predictors of best-corrected visual acuity (BCVA) at the final follow-up. Worse preoperative visual acuity and macular comorbidity were identified as independent predictors of poorer postoperative BCVA. Among macular pathologies, cystoid macular edema was most strongly correlated with reduced vision in the univariable analysis (β = 0.195; p = 0.016). In the subgroup analysis, worse preoperative visual acuity and macular comorbidity remained significant predictors (p 

Paediatric kidney transplant and school life: a qualitative study of childrens academic experiences in Lahore, Pakistan

Por: Saleem · J. · Asghar · R. S. · Ali · F. · Zafar · A. · Riaz · A. · Rashid · M. · Khan · F. · Mehmood · F. · Amjad · A. · Saqib · L. · Abbas · A.
Objectives

Paediatric kidney transplantation, while life-saving, presents significant academic challenges for children. Frequent hospitalisations, medical treatments and the psychosocial impact of chronic illness can severely disrupt educational trajectories. This study aimed to explore the post-transplant academic experiences of children from the perspective of their parents.

Design

A qualitative phenomenological study. Data were collected through in-depth, semistructured interviews and analysed using inductive thematic analysis.

Setting

The study was conducted in Lahore, Pakistan, with participants recruited from the registry of the Punjab Human Organ Transplantation Authority (PHOTA).

Participants

Thirteen parents of children who had undergone a kidney transplant and were enrolled in a formal school.

Results

Five major themes emerged from the analysis: (1) academic disruption and coping, detailing declines in performance and motivation alongside efforts to maintain engagement; (2) cognitive fatigue and emotional strain, encompassing reduced focus, memory difficulties and psychological distress; (3) school attendance, participation and support, highlighting frequent absenteeism, limited engagement in activities, and the critical role of institutional flexibility; (4) social identity and peer exclusion, revealing fears of stigma, self-isolation and misunderstanding from peers and (5) navigating the future, reflecting parental anxieties about long-term educational and career prospects alongside adaptive hope. The findings underscore that formal support systems in schools and healthcare settings are currently underdeveloped to meet these children’s complex needs.

Conclusions

This study illuminates the profound and multifaceted academic challenges faced by children after kidney transplantation. The results emphasise that a transplant is not merely a medical event but a life-altering experience with significant educational consequences. There is a critical need for integrated, targeted interventions that provide robust psychological support, flexible educational policies and comprehensive school reintegration programmes to ensure these children can achieve their full academic and personal potential.

Objectives

Chronic kidney disease (CKD) is a global health concern and a major long-term complication of diabetes, yet its burden remains understudied in regions with limited epidemiological data. This study aimed to evaluate the prevalence of CKD and its associated risk factors in the Iranian adult population, stratified by diabetes status.

Design

Population-based cross-sectional study.

Setting

Nationally representative survey across Iran (STEPS 2021).

Participants

17 607 adults aged ≥25 years with complete kidney function and albuminuria data, selected through systematic sampling with weighting to ensure national representativeness.

Primary and secondary outcome measures

CKD was defined as an estimated glomerular filtration rate (eGFR)

Results

The national prevalence of CKD was 11.9% (95% CI 11.2% to 12.6%), with 9.1% (8.5% to 9.9%) among individuals without diabetes and 28.6% (26.2% to 31.1%) among those with diabetes. According to KDIGO classification, 88.1% (87.4% to 88.8%) were at low risk, 9.0% (8.4% to 9.6%) at moderate risk, 2.0% (1.6% to 2.4%) at high risk and 0.9% (0.7% to 1.1%) at very high risk. Albuminuria was more prevalent than low eGFR in both groups with (22.5% (20.4% to 24.8%) vs 10.3% (8.7% to 12.1%)) and without (5.7% (5.2% to 6.3%) vs 4.3% (3.8% to 4.8%)) diabetes. Diabetes was more strongly linked to albuminuria than low eGFR and was progressively associated with higher risk categories (adjusted ORs (aORs) 2.41 (2.03–2.86) for moderate, 2.63 (1.74–3.97) for high, 3.93 (2.56–6.07) for very high vs low-risk). CKD prevalence was highest in northwest Iran, increased significantly with age, with a stronger association observed for low eGFR than albuminuria, and was associated with hypertension (aOR 2.41 (2.07–2.82)), dyslipidaemia (1.60 (1.31–1.94)), obesity (1.94 (1.59–2.36)), ischaemic heart disease (1.53 (1.25–1.87)) and physical inactivity (1.40 (1.20–1.62)). Higher socioeconomic status and education were associated with lower odds of CKD.

Conclusions

CKD is a major burden, especially in individuals with diabetes, with regional and socioeconomic disparities. Addressing risk factors, integrating CKD into non-communicable disease surveillance and prioritising it in global health agendas, including the Sustainable Development Goals, are essential.

Prevalence and associated factors of undernutrition among children under the age of 5 years: a cross-sectional study in riverbank erosion areas of Bangladesh

Por: Rahman · T. · Rashid · M. · Arafat · Y. · Fahim · M. · Sultana · P. · Merajul Islam · M.
Objectives

The study aimed to determine the prevalence and identify the associated factors of undernutrition among children under 5 years of age living in riverbank erosion areas in Bangladesh.

Study design

A community-based cross-sectional study.

Setting

The study was carried out in riverbank erosion-prone areas of the Tangail and Kushtia districts of Bangladesh, which were selected because they are highly vulnerable to riverbank erosion and related livelihood disruptions.

Participants

Participants were selected using a two-stage cluster sampling technique based on the criterion that mothers had at least one child under the age of 5 years.

Outcomes

Stunting, wasting and underweight were considered independently as outcome variables to assess nutritional status.

Methods

Descriptive analysis was performed to determine the prevalence of undernutrition, while the ² test and multivariable Poisson regression model were used to identify significantly associated factors with undernutrition among children under 5 years of age in riverbank erosion areas.

Results

The average prevalence of stunting, wasting and underweight was 37.74%, 22.64% and 9.81%, respectively. Results from the Poisson regression model showed that children who were average or large in size at birth had a much lower prevalence of all forms of undernutrition compared with those born very small. Female children had a 30% lower prevalence of stunting compared with male children. In addition, having educated parents, receiving four or more antenatal care visits and household livestock ownership were each associated with a lower prevalence of undernutrition.

Conclusion

The prevalence of stunting in this study was higher than that reported in the most recent Bangladesh Demographic and Health Survey 2022. Child size at birth, sex, parental education, antenatal care visits and household livestock ownership were identified as significantly associated factors with undernutrition in riverbank erosion areas of Bangladesh.

Background

Global discussions surrounding the medical use of marijuana have gained momentum; yet in Malaysia, cannabis remains strictly prohibited under the Dangerous Drugs Act 1952. Despite its legal status, there is growing public discourse on its potential therapeutic benefits. Understanding public acceptance is critical for informing future health policies and public education efforts.

Methods

This study used a cross-sectional design, web-based survey among Malaysians aged 18 years and above using convenience and snowball sampling methods. The survey collected data on sociodemographic characteristics, lifestyle factors (eg, smoking and drug use), awareness of medical marijuana and perceived risk. Multivariable logistic regression analysis was performed to identify factors associated with acceptance of medical marijuana decriminalisation.

Results

Out of 2047 respondents, 88.4% supported medical marijuana decriminalisation based on clinical evidence. Key predictors of acceptance included male gender (adjusted OR (AOR) 1.71; 95% CI 1.29 to 2.26), higher education (Bachelor’s degree AOR 1.56; 95% CI 1.09 to 2.23 and Master’s/PhD AOR 2.04; 95% CI 1.34 to 3.10), self-employment (AOR 1.84; 95% CI 1.22 to 2.77) and private sector employment (AOR 1.40; 95% CI 1.03 to 1.89). Behavioural factors, such as smoking (AOR 1.58; 95% CI 1.10 to 2.27), prior drug use (AOR 1.86; 95% CI 1.30 to 2.67) and low perceived risk (AOR 5.82; 95% CI 3.48 to 9.73), were also significantly associated with acceptance.

Conclusions

A large proportion of Malaysian adults supported the clinical use of medical marijuana. Acceptance was strongly associated with demographic and behavioural factors, particularly gender, education and perceived risk. These findings may guide the development of targeted public health education and inform future discussions on regulatory approaches in Malaysia.

Frailty and disability among older adults residing in Rohingya refugee camp in Bangladesh

by Afsana Anwar, Mahmood Parvez, Farhan Azim, Uday Narayan Yadav, Saruna Ghimire, Ateeb Ahmad Parray, Shovon Bhattacharjee, ARM Mehrab Ali, Rashidul Alam Mahumud, Md Irteja Islam, Md Nazmul Huda, Mohammad Enamul Hoque, Probal Kumar Mondal, Abu Ansar Md Rizwan, Suvasish Das Shuvo, Sabuj Kanti Mistry

Background

Frailty and disability often emerge with ageing and affect quality of life. Older adults residing in Rohingya refugee camp in Bangladesh are particularly susceptible to frailty and disability due to adverse physical and social environment along with limited health and social care services available in the camp. This study aimed to investigate the prevalence and factors associated with frailty and disability among Rohingya older adults living in Bangladesh.

Methods

This cross-sectional study was conducted among older adults aged ≥60 years residing in the Rohingya refugee settlement in Bangladesh. The primary outcomes were frailty and disability, explored using the ‘Frail Non-Disabled (FiND) questionnaire. Data were collected face-to-face during November-December 2021, using a semi-structured questionnaire. A multinomial logistic regression model was used to identify the factors associated with frailty and disability.

Results

The majority of participants (n = 864) were aged 60–69 years (72.34%), male (56.25%), married (79.05%), and without formal education (89.0%). The study revealed a high prevalence of frailty (36.92%) and disability (55.21%) among the participants. The multinomial regression analysis showed that the likelihood of experiencing disability was significantly higher among participants who were aged 70–79 years (RRR = 2.65, 95% CI: 1.25, 5.66) and ≥80 years (RRR = 8.06, 95% CI: 1.05, 61.80), were female (RRR = 3.93, 95% CI: 1.88, 8.1.9), had no formal education (RRR = 4.34, 95% CI: 2.19, 8.63), were living in a large family (RRR = 1.82, 95% CI: 1.05, 3.18) and were suffering from non-communicable diseases (RRR = 2.36, 95% CI: 1.32, 4.22) compared to their respective counterparts. The regression analysis also revealed that frailty was significantly higher among participants who were female (RRR = 2.82, 95% CI: 1.34, 5.94), were suffering from non-communicable diseases (RRR = 2.28, 95% CI: 1.27, 4.09), and had feeling of loneliness (RRR = 2.16, 95% CI: 1.11, 4.22).

Conclusions

The findings underscore the need for long-term care and health promotion activities to alleviate the burden of frailty and disability among older adults in humanitarian settings. Efforts should particularly target the most vulnerable groups- older individuals (≥80 years), women, those without formal education, those living in large families, and those with non-communicable diseases.

Development and evaluation of a diagnostic aiding tool for differentiating tropical fevers using artificial intelligence approach: a study protocol from tertiary care hospital in South India

Por: Chitrapady · S. · Rajendran · R. · Haritha · K. · Tejashree · M. U. · Rashid · M. · Poojari · P. G. · Kunhikatta · V. · Varma · M. · Devi · V. · Acharya · D. · Khan · S. · Thunga · G.
Introduction

Application of artificial intelligence (AI) tools in the healthcare setting gains importance especially in the domain of disease diagnosis. Numerous studies have tried to explore AI in the diagnosis of various diseases, including tropical fevers such as dengue and malaria. However, there is a lack of standard guidelines to develop the AI models, the gap between clinical and engineering expertise and clinical validation of the models, and hence there is a critical need for the development of an integrated diagnostic tool which uses demographical, laboratory variables and epidemiological parameters of patient and provides early prediction.

Methods and analysis

The present study aimed to develop and evaluate a machine-learning (ML) prediction tool for differential diagnosis of tropical fevers for adult patients (>18 years) using a three-phase approach in a tertiary care centre in South India by January 2026. Phase involves identification of the prevalent tropical fevers and associated clinical parameters to develop the AI model through a retrospective audit and qualitative interview. Phase Ⅱ involves retrospective data collection from hospital medical records for finalised diseases (1000 cases per disease) and clinical parameters, with data being used for model development using the Python language. Support vector machine, logistic regression, K-Nearest Neighbors, Naïve Bayes and ensemble models such as decision tree and Random Forest will be employed along with explainable AI techniques. They are used as they are easy to understand and interpret, well established, most effective for structured data, enhancing the transparency and interpretability of the predictive machine learning models, and their use has been widely supported in previous studies across various contexts. Suitable statistical parameters like specificity, sensitivity and area under receiver operating characteristic (AUROC) will be applied to evaluate model performance. In phase , the developed model will be implemented prospectively to assess the feasibility of model implementation. Model performance such as specificity, sensitivity and AUROC will be calculated, and the finally developed model will be implemented in a single tertiary care hospital to evaluate its overall performance.

Ethics and dissemination

Ethical approval for the study has been obtained from the institutional ethics committee of the Kasturba Medical College and Kasturba Hospital, Manipal (IEC number: 6/2024). Informed consent will be taken for obtaining the data of the patient for the evaluation of the model in the third phase of the study, and data will be kept confidential. The study results will be disseminated by publishing them in a peer-reviewed journal.

Trial registration number

The protocol has been registered with the Clinical Trial Registry of India (CTRI) (CTRI/2024/04/065866) and approved on 16 April 2024.

A multi-image codebook approach for secure text transmission

by Omar Fitian Rashid, Saba A. Tuama, Humam Al-Shahwani

In modern digital communication, Confidentiality of text transmission is remains a concern in the current online communication as cyber threats and intrusion. To address these challenges, this paper proposes a dual-layered security system that integrates cryptography and multi-image steganography to strengthen text protection during transmission. The cryptography layer is done based eight steps; in the first one, the message is converted to ASCII format, then convert the ASCII values into their equivalent binary numbers and make a complement to the binary values where each 0’s becomes 1’s and vice versa. In the next step, it needs to enter a key that includes a combination of characters, numbers, and special characters. This key is also converted to binary, and then the XOR operation is made between the message of the binary values and the key. In the fifth step, switching the values of each two adjacent binary values are together and converted to decimal values. While the second layer embeds the ciphertext in several cover images using a randomized codebook along with the Least Significant Bit (LSB) substitution, thus enhancing undetectability. Experimental evaluation demonstrates fast execution times for both the encryption/decryption processes and the multi-image hiding/extraction procedures. The achieved results validate that the proposed system provides an efficient and highly secure framework for protecting sensitive information.

Introduction

In Canada, many families want to breastfeed, but there are several common challenges they may encounter. Currently, 91% of Canadian families initiate breastfeeding after giving birth, yet only 38% of babies are breastfed exclusively to 6 months. In 1991, the Breastfeeding Committee for Canada (BCC) was established to implement the World Health Organization’s Ten-Step Baby-Friendly Hospital Initiative, a series of evidence-based in-hospital practices to support families to breastfeed. Then, in recognition of the need to support breastfeeding beyond the hospital setting, the BCC expanded the Baby-Friendly Initiative (BFI) to apply the Ten Steps to both hospitals and community health settings. However, uptake of the BFI Ten Steps in community settings has been low and methodology on how to optimise implementation of the Ten Steps in community is not well developed. Therefore, the objective of this project is to develop and evaluate a quality improvement collaborative with 25 community health services from across Canada to learn how to best support the implementation of the BFI Ten Steps in community, with the ultimate goal of improving breastfeeding outcomes.

Methods and analysis

This protocol describes the activities of the Community Baby-Friendly Initiative Collaborative (CBFI-C) and the methods used to evaluate its effectiveness. We will use the Institute for Healthcare Information Breakthrough Series (IHI-BTS) model, a proven quality improvement model that has been widely used in clinical settings, but is not yet widely used in community settings. The IHI-BTS combines three virtual learning sessions with action cycles that allow the participating sites time to test and track small practice changes. Sites will be asked to track care indicator and breastfeeding outcome data, engage in monthly webinars, receive coaching from trained mentors, participate in focus groups and participate in a final summative workshop. We will use a multi-site case study approach, combining aggregate care indicator data and qualitative data from webinars, focus groups and workshops to evaluate how the CBFI-C model supports community sites in the process of implementing the BFI Ten Steps.

Ethics and dissemination

Ethics approval for this evaluation was obtained from the CHIPER Health Research Ethics Board (Number HS26947-H2025:157)). The results of the CBFI-C evaluation will be shared in a report, peer-reviewed publications and presentations to government and academic audiences. The findings will inform effective quality improvement strategies to enhance uptake of the BFI in community health settings.

Introduction

Self-care plays a pivotal role in the management of heart failure (HF). Health literacy and empowerment are considered the prerequisites of effective self-care. This project aims to improve self-management in people with HF by describing, analysing and enhancing the communication practices of clinicians and patients to support people with HF to increase their health literacy skills and participate in shared decision-making.

Methods and analysis

A multimethod research design incorporating an interview component, a concurrent mixed-methods component and a pilot intervention study is used. The study is currently being conducted at two Australian hospitals in metropolitan areas (one public and one private). The interview component involves semistructured interviews with healthcare providers and hospital executives and managers at the participating sites to explore perceived barriers and facilitators to HF self-management and understand the institutional context of HF care. The concurrent mixed-methods components include: (a) tracking and audio recording the clinical interactions of patients with HF (n=30) during their hospitalisation and up to 6 months after discharge and semistructured interviews with the patient (and the carer) and the participating clinician after each clinical interaction and (b) collecting longitudinal survey data (n=180, patients) to track patients’ health literacy, empowerment and self-management over 6 months.

Introduction

Radioembolisation (RE) is gaining traction as a robust treatment option for patients with hepatocellular cancer (HCC) across all cancer stages. RE allows the delivery of targeted high-dose radiation directly to tumours, with relative sparing of the surrounding liver tissue. Traditionally, radiation has been delivered using 90Yttrium ([90Y]Y)-labelled microspheres, either glass or resin. The success of RE is dependent on the dose delivered to the tumour. When using [90Y]Y microspheres, dose prediction is calculated through a 99mTechnitium ([99mTc]Tc)-macroaggregated albumin (MAA) scan, which allows the calculation of the dose to be administered to the tumour. However, [99mTc]Tc-MAA is not a true surrogate of [90Y]Y microspheres, and this will impact on the final dose delivered. [166Ho]Ho, like [90Y]Y, is a beta emitter but unlike [90Y]Y also emits gamma-radiation, allowing for quantitative nuclear imaging. The primary aim of this pilot study was to investigate the safety and efficacy of dosimetry-based individualised 166Holmium ([166Ho]Ho-RE) in patients with HCC.

Methods and analysis

15 eligible participants will be recruited to receive [166Ho]Ho-RE. The primary objective is to establish the toxicity profile of dosimetry-based individualised [166Ho]Ho-RE. The secondary objective is to assess efficacy as measured by modified Response Evaluation Criteria in Solid Tumours (mRECIST) and Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 criteria. Additional exploratory objectives include quality of life assessment and identification of a radiomic signature of response. The results from this study will be combined with the prospective iHEPAR study to form a larger analysis.

Ethics and dissemination

The study has received approval from the East Midlands—Nottingham 1 Research Ethics Committee—approval number 23/EM/0239. The study will be performed in compliance with the Declaration of Helsinki and the principles of Good Clinical Practice. Signed informed consent will be obtained from each patient before study entry. The results will be disseminated through publication in a peer-reviewed scientific journal.

Exploring the lived experiences of first blood among adolescent girls in Pakistan: a phenomenological qualitative study

Por: Shahzad · R. B. · Aftab · M. M. · Shahzad · H. · Saleem · J. · Rashid · M. · Arshad · M. · Abbas · S.
Objective

The study aims to explore the experiences of adolescent girls with the onset of their first menstruation in the context of Pakistan and to highlight the sociocultural aspects that shape those experiences.

Design

The study employs an exploratory phenomenological approach.

Setting

This study has been conducted at a public sector higher education institute, University of the Punjab, Pakistan. Female students enrolled in the first semester of the undergraduate degree programme were included in the study using a predefined inclusion and exclusion criteria.

Participants

Data was collected from six 18 years old girls who had their menarche in the last 6 years through face-to-face in-depth interviews using a semi-structured interview guide from June 2024 to August 2024. The interviews were audio-recorded given the written consent of the participants. Transcripts were analysed thematically following Braun and Clarke’s framework.

Results

Thematic analysis of six interviews revealed three major themes: (1) Experience of first blood: emotional, social and practical difficulties; (2) The problem of mismanagement of first menstruation and the strategies used; and (3) Restrictions during menstruations. The study found that adolescent girls are provided with little to no prior knowledge regarding menarche and menstruation that causes various complexities and vulnerabilities. The social and cultural expectations and the gendered norms construct the experiences of the adolescent girls regarding their first menstruation, while the idea of womanhood is preserved in the society by restricting, isolating and alienating the adolescent girls and modifying their conduct and behaviour accordingly.

Conclusion

Menarche is often experienced as distressing, secretive and isolating for adolescent girls in Pakistan. Educational interventions in families and schools are needed to provide accurate, timely information and to support girls in navigating this transition with confidence and dignity.

Scoping review protocol to map nutrition and food-related interventions targeting young people living with HIV/AIDS

Por: El Rashidi · N. · Kehoe · S. H. · Jesson · J.
Introduction

Adolescents living with HIV are at a high nutritional risk. Ensuring optimal nutrition and food security is fundamental for promoting the health of adolescents and youth living with HIV/AIDS (AYLHIV), preventing HIV disease progression and improving quality of life. The objective of this scoping review is to map and identify the current literature concerning nutrition and food-related interventions addressing AYLHIV.

Methods and analysis

The study will follow the Joanna Briggs Institute methodology for scoping reviews. We will search for relevant studies in the following databases: MEDLINE, EMBASE, Web of Science and Google Scholar. We will perform additional searches of the grey literature using snowball search and citation tracking and manual searches of institutional websites. Titles and abstracts will then be screened by two independent reviewers for assessment against the inclusion criteria. Disagreements will be resolved through discussion. A data extraction form will be used to guide the data extraction.

Ethics and dissemination

This review will involve the collection and analysis of secondary sources that have been published and/or are publicly available. Therefore, ethics approval is not required. The results will be published in an international peer-reviewed journal, presented at scientific conferences and disseminated through digital science communication platforms.

Trial registration number

The protocol is registered in the Open Science Framework: https://doi.org/10.17605/OSF.IO/HGBKV.

Clinical and economic impact of cost-intensive vs non-cost-intensive antihypertensive therapies: a retrospective study using real-world data from Japan

Por: Yoshihara · H. · Maeda · N. · Tonoike · T. · Ohno · H. · Nishiuchi · S. · Igarashi · A.
Background

Hypertension is a major health challenge imposing substantial economic and health burdens worldwide. This study compared treatment outcomes and costs between cost-intensive and non-cost-intensive pharmacotherapies, defined by prescribing intervals and the type of drugs, using electronic health record (EHR) data from multiple healthcare facilities, focusing on the type of antihypertensive drug and prescribing patterns.

Design

A retrospective cohort study. A mixed-effects Cox proportional hazards model was used to investigate the association between cardiovascular events and healthcare resource use.

Setting

EHRs from 34 primary care facilities in Japan.

Participants

Patients prescribed either angiotensin receptor blockers (ARBs) alone or calcium channel blockers (CCBs) alone were included.

Results

During 6629 person-years of follow-up, 71 events were observed. Model diagnostics confirmed the proportional hazards assumption and substantial inter-clinic heterogeneity. The type of drug (ARBs or CCBs) had no statistically significant impact on the incidence of cardiovascular events (HR 0.999, 95% CI 0.603 to 1.655). Similarly, shorter prescribing intervals (less than 36 days) were not significantly associated with the outcome (HR 1.724, 95% CI 0.906 to 3.279). The mean annual medical cost per patient for the cost-intensive (ARB with short prescribing intervals) and non-cost-intensive (CCB with long prescribing intervals) groups was Japanese yen (JPY) 137 023 and JPY 85 911, respectively. Sensitivity analysis using different time windows yielded similar results, confirming the robustness of the findings.

Conclusion

No apparent reduction in cardiovascular events associated with the use of ARBs or shorter prescribing intervals was observed despite the elevated cost caused by intensive pharmacotherapy and frequent clinic visits.
