Global ageing populations require accessible, non-invasive tools for early detection and monitoring of neurological chronic and neurodegenerative diseases. Current diagnostic methods face limitations including invasiveness, high costs and infrequent clinical assessments. The human voice has emerged as a promising digital biomarker, with vocal characteristics reflecting physiological and cognitive changes associated with conditions like dementia and Parkinson’s disease. While artificial intelligence (AI) and machine learning have enabled sophisticated vocal analysis, the literature remains fragmented without comprehensive synthesis. This scoping review protocol delineates a systematic approach to collate and synthesise existing research on the application of AI-driven audio biomarkers for the detection and management of neurological diseases (eg, cognitive decline, Parkinson’s disease, Alzheimer’s, dementia and depression) in older adults aged 65 years and above.
This scoping review will be conducted in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines and the methodological framework proposed by Arksey and O’Malley, incorporating recent methodological advancements. The eligibility criteria for study selection will be formulated using the PCC (Population, Concept, Context) framework. A comprehensive literature search will be performed across several electronic databases, including PubMed/MEDLINE, Scopus, Web of Science, IEEE Xplore, Embase, Compendex, CINAHL, Scientific Information Database (SID), Magiran, IranMedex and Barakat Knowledge Network System (BKNS). The search will encompass peer-reviewed articles published in Persian and English from 1 January 2012 to 31 March 2026. Two independent reviewers will screen titles, abstracts and full texts and extract data according to the predefined PCC-based eligibility criteria. Discrepancies will be resolved through discussion or, if necessary, by consultation with a third reviewer. The results will be synthesised and presented narratively, accompanied by summary tables, charts and figures to address each research question.
The Research Ethics Committee of Tabriz University of Medical Sciences approved the protocol for this scoping review (approval number: IR.TBZMED.VCR.REC.1404.223). They concluded that since the review involves only analysis of existing literature without direct patient involvement or clinical procedures, it meets the relevant ethical standards. Results from the review will be shared through peer-reviewed journals and conference presentations to provide valuable insights for researchers, clinicians and policymakers on the use of audio-based biomarkers in older adults.

Childbirth readiness can reflect women’s childbirth readiness in terms of knowledge, psychological aspects and planning. The purpose of this study was to evaluate childbirth readiness, its related factors and consequences in Iranian pregnant women.
This longitudinal study was the first stage (quantitative stage) of a sequential explanatory mixed-method study. It followed women during late pregnancy (from 37 weeks of gestation) and the postpartum period (4–6 weeks after childbirth) from March to September 2023.
Health centres of Tabriz, Iran.
This study involved 360 pregnant women with a gestational age of 37 weeks and above, selected via cluster sampling. Participants were excluded for high-risk pregnancies, unfavourable incidents in the last 3 months, mental-psychological diseases or a prior caesarean section.
Childbirth readiness and its related factors were assessed using several instruments completed from the 37th week of pregnancy onward, including the Childbirth Readiness Scale, a sociodemographic questionnaire, the Pregnancy Experience Scale and the Wijma Delivery Expectancy/Experience Questionnaire Version A. The consequences of childbirth readiness were then evaluated 4–6 weeks post partum using the Childbirth Experience Questionnaire, the Edinburgh Postnatal Depression Scale and the Postpartum-Specific Anxiety Scale.
The mean (SD) childbirth readiness score was 67.83 (9.41) out of 90. In the adjusted general linear model (GLM), several factors were significantly associated with lower readiness. These included a higher fear of childbirth score (β –0.12, 95% CI –0.16 to –0.08, p
Key factors associated with readiness included fear of childbirth, obstetric history (gravidity, parity, history of abortion and participation in childbirth readiness classes), maternal education, home ownership, husband’s occupation—though several associations showed small effect sizes. After adjustment, readiness did not independently predict childbirth experience or postpartum mental health. The low participation rate in readiness courses highlights a major service gap. Integrating readiness assessment into prenatal care and expanding access to targeted education are recommended to improve outcomes such as birth satisfaction and caesarean rates.

BackgroundUnintended pregnancy among female sex workers (FSW) is a pressing reproductive health concern attributable to risky sexual behaviors, healthcare inequities and poor negotiation powers with male sex partners. However, evidence is scarce on the prevalence and determinants of unintended pregnancies among FSW, which is crucial for enhancing reproductive healthcare. This analysis aims to measure the prevalence of lifetime unintended pregnancies and their associated factors.
MethodsA cross-sectional study was conducted on 327 FSW in Jashore (a border belt district of Bangladesh) from September 2022 to March 2023. Participants were recruited through take-all sampling. Data were collected on the lifetime history of unintended pregnancies and other relevant variables through face-to-face interviews. Chi-square statistic was used to compare the characteristics of FSW reporting unintended pregnancies. To assess the net association of factors associated with unintended pregnancy, multiple logistic regression was applied.
ResultThe lifetime prevalence of unintended pregnancies was reported at 75.8% (95%CI: 71.0–80.1). Among those who reported unintended pregnancies, 37.1% (95%CI: 30.8–43.8) had no education, 39.9% (95%CI: 32.8–47.5) were 25–34 years old, 49.6% (95%CI: 39.3–59.9) were currently married and 62.9% (95%CI: 49.7–74.4) earned ≤10,000 BDT per month compared to those who did not report lifetime unintended pregnancies. The likelihood of unintended pregnancies was significantly higher among those who reported having sex with non-transactional male sex partners (AOR: 2.4, 95%CI: 1.1–5.3, p = 0.036) than those who never had sex with any non-transactional male sex partner. The likelihood was also higher among those who reported rape in their lifetime (AOR: 2.0, 95%CI: 1.0–3.8, p = 0.037) and who self-reported mental health problems (AOR: 2.1, 95%CI: 1.0–4.2, p = 0.045) within the past year, compared to their counterparts.
ConclusionThis study highlights the considerable prevalence and associated determinants of unintended pregnancies among FSW in Jashore. These determinants need to be considered to strengthen reproductive healthcare interventions and policies for FSW. Reproductive health of FSW cannot be improved unless these factors are addressed in the ongoing interventions.

Terrorism-related disasters (TRDs) continue to exert profound and recurring pressures on healthcare systems, particularly in vulnerable regions like Pakistan. Although pharmacists are increasingly recognized as an essential component of disaster management, there is a clear gap in the literature regarding their preparedness, experience, and specific roles in responding to TRDs particularly in low and middle-income countries. This study aimed to explore the preparedness, experiences, and response strategies of pharmacists managing TRDs at the Trauma Centre of Sandeman Provincial Hospital, Quetta, Pakistan. A qualitative design was adopted, guided by the Consolidated Criteria for Reporting Qualitative Research. Semi-structured, face-to-face interviews were conducted with pharmacists (n = 10) providing services at the Trauma Centre. Data were audio-recorded, transcribed verbatim, validated by participants, and analyzed using thematic content analysis. Analysis revealed five overarching themes: (1) pharmacists’ experiences with terrorism-related incidents and existing response mechanisms; (2) professional and personal responses to emergencies, reflecting both commitment and psychological burden; (3) preparedness challenges, including lack of disaster management training, limited awareness of policies and protocols, and inadequate understanding of triage and coordination; (4) barriers such as security risks, pharmacy curriculum deficiencies, insufficient experiential learning, and minimal involvement in planning and management activities; and (5) recommendations for strengthening capacity, including revising curricula, implementing structured training programs, conducting regular disaster drills, and expanding pharmacists’ roles in preparedness and response. Findings revealed a pronounced lack of formal training in disaster management, limited awareness of protocols and triage systems, and minimal involvement of pharmacists in planning and coordination activities. Despite strong professional commitment and frontline engagement, pharmacists’ contribution remain constrained by educational, structural, and policy-level shortcomings. The study highlights the urgent need for integrating disaster management into pharmacy curricula, implementing structured training programs and regular disaster drills, and expanding pharmacists’ roles within institutional and national disaster preparedness frameworks.by Nurdiana Mohammad Hussin, Nik Ruzyanei Nik Jaafar, Idayu Badilla Idris, Azmawati Mohammed Nawi
Individuals with breast cancer (BC) experience significant psychological distress, yet their utilization of mental health services remains low. This study identified key factors influencing help-seeking behavior through integrated Theory of Planned Behavior (TPB) and Health Belief Model (HBM) frameworks. We conducted in-depth interviews (IDIs) with eight BC patients and nominal group technique (NGT) with six health professionals, followed by Fuzzy Delphi Method (FDM) to assess expert consensus. The IDIs revealed that the individuals with BC recognized the value of professional psychological support but were reluctant to engage with these services personally. The participants identified emotional thresholds for help-seeking, expressed preference for informal support networks, and demonstrated varied understanding of mental health professional roles. The FDM evaluation demonstrated strong expert consensus across all assessed elements, particularly those related to emotional support mechanisms. Three barrier categories emerged: individual factors (mental health literacy, autonomy preferences), social factors (family support, cultural stigma), and systemic factors (healthcare integration gaps). Expert consensus exceeded 80% agreement across all domains.This study identified a complex interplay between individual psychological barriers and systemic factors affecting mental health help-seeking among individuals with BC. Effective interventions must address psychological barriers and healthcare delivery factors while respecting individual autonomy in coping choices. A multi-level approach targeting individual education, family support systems, and healthcare integration is recommended to improve mental health service utilization among individuals with BC.Burn injuries are a significant cause of morbidity and mortality globally; however, limited data are available from low- and middle-income countries such as Jordan. This study aimed to describe burn patient presentation, initial management and factors associated with in-hospital mortality. A retrospective descriptive study was conducted using records of 493 patients admitted to a national referral centre in Jordan between 2018 and 2022. The sample was predominantly male (61.5%) with a mean age of 19.6 years (SD = 21); children under 18 years comprised 58.4%. The mean total body surface area (TBSA) burned was 18%. Flame (50.1%) and scald (44.6%) injuries were most common. Inhalation injury occurred in 25.8% and 21.3% required mechanical ventilation. The hospital mortality rate was 15.6%, significantly associated with TBSA, age, inhalation injury and low serum total protein. Baux and revised Baux scores showed high predictive accuracy (AUC = 0.902 and 0.918). Logistic regression identified TBSA, age, inhalation injury and total protein level as independent predictors of mortality. Burn injuries in Jordan disproportionately affect children and are associated with substantial mortality. Early identification of high-risk patients using validated scores and prompt nutritional and respiratory interventions are essential. Multicentre studies and a national burn registry are recommended to guide future policy and care improvements.

BackgroundFrailty 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.
MethodsThis 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.
ResultsThe 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).
ConclusionsThe 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.

BackgroundStreet adolescents often engage in early sexual activity, have multiple partners, and are at high risk of sexual abuse and exploitation. Despite the significance of this issue, there is a critical gap in understanding the sexual and reproductive health (SRH) needs, practices, and challenges of this marginalized population in Bangladesh, which this study aimed to explore.
MethodsA cross-sectional study was conducted from August to December 2023, involving 311 street adolescents aged 16–19 years in Sylhet City Corporation, Bangladesh. Data were collected through face-to-face interviews using a semi-structured questionnaire. The questionnaire covered sociodemographic characteristics, pubertal changes, SRH status, and SRH-seeking behaviors.
ResultsOf all participants, 62.8% were males and 37.2% were females, with a mean age of approximately 17.3 years for both sexes. Sexual intercourse was reported by 32.56% of participants, with a significant gender disparity (76.79% females vs. 6.35% males, p Conclusion
Street adolescents in Sylhet City face severe SRH challenges, including high rates of sexual abuse, low contraceptive use, and limited STD knowledge, with significant gender disparities, which should be addressed through appropriate and urgent interventions.

Large Language Models (LLMs) have ushered in a transformative era in Natural Language Processing (NLP), reshaping research and extending NLP’s influence to other fields of study. However, there is little to no work examining the degree to which LLMs influence other research fields. This work empirically and systematically examines the influence and use of LLMs in fields beyond NLP. We curate 106 LLMs and analyze ∼148k papers citing LLMs to quantify their influence and reveal trends in their usage patterns. Our analysis reveals not only the increasing prevalence of LLMs in non-CS fields but also the disparities in their usage, with some fields utilizing them more frequently than others since 2018, notably Linguistics and Engineering together accounting for ∼45% of LLM citations. Our findings further indicate that most of these fields predominantly employ task-agnostic LLMs, proficient in zero or few-shot learning without requiring further fine-tuning, to address their domain-specific problems. This study sheds light on the cross-disciplinary impact of NLP through LLMs, providing a better understanding of the opportunities and challenges.To examine the associations between food-related behaviours and nutrient intake on nutritional status among clients undergoing Community-Based Treatment and Rehabilitation (CBTaR) in Kelantan, Malaysia.
Cross-sectional analytical study.
Seven CBTaR centres (n=7) across the state of Kelantan, Malaysia.
A total of 393 adult clients (aged 18 years and above) enrolled in CBTaR programmes between June and December 2022 were selected through stratified random sampling.
The primary outcome was nutritional status, assessed using body mass index. Secondary outcomes included nutrient intake (macronutrients and micronutrients) and food-related behaviours (emotional eating, external eating, restrained eating and food addiction), measured through Bahasa Malaysia validated questionnaires and 24-hour dietary recalls. All variables were introduced into the structural equation modelling to examine the associations among these variables and their association with nutritional status.
The results revealed that food-related behaviour was significantly associated with the nutrient intake (β=–0.524, p≤0.001). Additionally, the drug use profile significantly determined the food-related behaviour (β=–0.129, p=0.006) and nutritional status (β=–0.134, p=0.007). Nutrient intake was found to be a significant predictor of nutritional status (β=–0.213, p≤0.001). Sociodemographic and drug use profiles were significantly correlated with nutritional outcomes through behavioural and dietary associations. Importance-performance map analysis identified nutrient intake as the most impactful variable, highlighting the need for urgent intervention (R2=0.272).
This study highlights that nutrient intake is a significant predictor associated with food-related behaviours on nutritional status among individuals with substance use disorder. Integrating nutrition counselling and behavioural interventions into CBTaR services may improve recovery and long-term health outcomes.
Systemic sclerosis (SSc) is an autoimmune disorder causing progressive fibrosis of internal organs and skin, leading to increased thickness and rigidity. It frequently results in malnutrition, which can decrease survival rates and physical performance, while also imposing financial burdens on healthcare systems and society. Multimodal nutritional interventions may encompass various approaches, including nutritional counselling, consumption of oral nutritional supplements and disease-specific dietary regimens based on nutritional needs. The present clinical trial is designed to examine the effectiveness of multimodal nutritional intervention on nutritional status, quality of life, food intake, body composition and fatigue in patients with SSc.
This is a parallel, randomised, placebo-controlled clinical trial that will investigate the impacts of multimodal nutritional interventions in SSc patients. 46 qualified SSc participants will be chosen at random and given multimodal nutritional intervention or dietary recommendations for a period of 8 weeks. The primary outcomes of this study are changes in nutritional status and quality of life. The secondary outcomes include changes in body composition, fatigue, body weight, body mass index and calf circumference. Statistical analysis will be conducted using the SPSS software (Version 24).
The current trial received approval from the Medical Ethics Committee of Tehran University of Medical Sciences, Tehran, Iran (IR.TUMS.MEDICINE.REC.1403.345). The findings will be submitted to international, peer-reviewed publications and presented at national and international conferences.

IntroductionAllergy is a form of chronic illness with an increasing prevalence globally. Adequate knowledge among the community about the causes, symptoms, and treatment of allergy is crucial in preventing the associated life-threatening complications. Limited research has been conducted in Palestine regarding this health priority. The current study aimed to assess the Palestinian community’s level of knowledge regarding allergy.
MethodsAn observational cross-sectional study was conducted using an online questionnaire targeting Palestinians aged 18 years and older between 1 June 2024 and 26 January 2025. The questionnaire gathered demographic information about the participants and assessed their knowledge level concerning allergy.
ResultsA total of 1002 participants were included in the study. The mean age of the participants was 30.33 years. 66.1% of the participants were females, 60.2% were unmarried, 60.1% had possessed a bachelor’s degree, 63.1% had a personal history of allergy, and 82% reported knowing of someone with allergies. The mean knowledge score about allergies was 5.4 out of 10, with over half of the participants having an average level of knowledge (4–6). The knowledge score about allergies was significantly different based on the participants’ sex, marital status, place of residence, educational level, and occupation (p-value Conclusion
The Palestinians’ knowledge of allergy is considered good regarding its common causes and symptoms. However, there is still inadequate knowledge about the treatment of allergy and its less common causes. The community awareness of allergy should be improved through targeted campaigns and brochures aimed at achieving earlier diagnosis and proper management to prevent the development of life-threatening complications.
This study aimed to explore and describe the experiences and perceptions of mothers of children with leukaemia regarding the transition of care from hospital to home.
A qualitative content analysis with a conventional approach was employed, and this report follows the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist.
Thirteen mothers of children with leukaemia were recruited using purposive sampling from two Iranian paediatric hospitals. Data were collected through in-depth, semi-structured interviews conducted between 2023 and 2024 and analysed using conventional qualitative content analysis.
Drowning in the Vortex of Fear and Doubt emerged as the central theme, encapsulating the shared experiences of mothers of children with leukaemia. This overarching theme comprised five categories: (1) Fear of Unpredictable and Life-Threatening Complications, (2) Paradoxical Concerns About Discharge, (3) Doubts and Hopelessness About Treatment Effectiveness, (4) Stress Regarding the Child's Future Life Trajectory and (5) Sense of Helplessness in Alleviating the Child's Suffering.
The findings underscore the need to provide comprehensive supportive services for parents of children with leukaemia. Policymakers and healthcare teams should prioritise initiatives that enhance parental awareness, deliver psychosocial support and empower families to navigate the arduous path of care and treatment with greater trust and confidence.
Ensuring the well-being and comfort of both the child with cancer and the parents throughout the treatment process is essential for improving care outcomes.
The study is reported according to the COREQ.
Mothers of children with leukaemia participated as interviewees and contributed to ensuring the rigour of the study through data validation.

Network physiology is a multidisciplinary field that offers a comprehensive view of the complex interactions within the human body, emphasising the critical role of organ system connectivity in health and disease. This approach has the potential to provide pathophysiological insights into complex and emerging diseases. This study aims to evaluate the effectiveness of physiological network mapping in predicting outcomes for COVID-19 patients, using data from the first wave of the pandemic. Routine clinical and laboratory data from 202 patients with COVID-19 were retrospectively analysed. Twenty-one physiological variables representing various organ systems were used to construct organ network connectivity through correlation analysis. Parenclitic network analysis was also employed to measure deviations in individual patients’ organ system correlations from the reference physiological interactions observed in survivors. We observed distinct features in the correlation network maps of non-survivors compared to survivors. In non-survivors, there was a significant correlation between the level of consciousness and the liver enzyme cluster, a relationship not present in the survivor group. This relationship remained significant even after adjusting for age and degree of hypoxia. Additionally, a strong correlation along the BUN–potassium axis was identified in non-survivors, suggesting varying degrees of kidney damage and impaired potassium homeostasis in non-survivors. These findings highlight the potential of network physiology as a valuable tool for uncovering complex inter-organ interactions in emerging diseases, with applications that could support clinicians, researchers, and policymakers in future epidemics.by Soha Albeitawi, Mohammad Talal Al-zubi, Anas Aljaiuossi, Murad Shatnawi, Ahlam Al-Kharabsheh, Fadi Sawaqed, Emad Aborajooh, Walid I.

BackgroundClinical preceptors serve as vital educators, so it is essential to enhance their effectiveness by developing a competency-based development program. In this study, we explored the challenges faced by preceptors and students, and measured the educational needs of preceptors, to inform the design of a syllabus for a preceptor development program.
MethodsThis was a sequential multi method study utilizing a structured questionnaire survey and focus group discussions among a representative sample of medical students in their fourth, fifth, and sixth years in addition to preceptors from the six public medical schools in Jordan.
ResultsThematic analysis of focus group discussions revealed six themes: admission policy, training environment, curriculum gaps, trainers and mentorship, learners, and dissemination. The most important training needs documented by preceptors were teaching in the clinical setting, mentoring skills, simulation, assessment in the clinical setting, and providing feedback. Accordingly, a competency-based preliminary syllabus was developed.
ConclusionIt is essential to enrich the skills of preceptors regularly based on a needs assessment. Further long term studies are required to investigate the effectiveness of the proposed syllabus after implementation.

The COVID-19 pandemic has had a devastating impact worldwide, with Iran being one of the hardest-hit countries in the Middle East. Understanding the factors that influence the spread of the virus is crucial for developing effective mitigation strategies. This study aims to investigate the geographical and climatic risk factors associated with COVID-19 incidence in the Kohgiluyeh and Boyer-Ahmad Province of southwest Iran during the 2020−2021 epidemic period. The study involved mapping the residential addresses of 15,585 patients with COVID-19 during 2020–2021. Geographical Information System (GIS) evaluated the effects of geographical and climatic determinants, including temperature, rainfall, humidity, evaporation, elevation, slope, and land cover, on COVID-19 occurrence. The data were analyzed using univariate and multivariate binary logistic regression. In the univariate model, significant climatic factors affecting COVID-19 susceptibility included elevation (pTo enhance the quality of surgical care, complications need to be minimised. Consequently, comprehending the occurrence and risk elements for postoperative complications is essential. Subsequently, we will apply machine learning (ML) algorithms to build risk factor prediction models that will assist surgeons in identifying the risk factors associated with the development of postoperative complications after general surgery.
This research will take place at a tertiary referral medical centre located in Bandar Abbas, Hormozgan, Iran. The inclusion criteria are (1) individuals aged 18 years or older who have any type of general surgery and (2) hospitalised from September 2025 to September 2026. Individuals with insufficient data will be excluded. The main outcomes of the study are complications within 30 days of surgery. Patients will be divided into two groups based on whether they develop complications or not. The predictors are classified as (1) patient-related factors, (2) surgery-related factors and (3) postoperative factors. We intend to detect postoperative complications following general surgery using four distinct supervised ML techniques: (1) logistic regression, (2) decision trees, (3) random forests and (4) extreme gradient boosting. Accuracy, precision, recall and F1 score will be used to evaluate the performance of ML models.
With approval from the Hormozgan University of Medical School Research Ethics Board (IR.HUMS.REC.1404.137), we will carry out a forward-looking analysis of the medical records of patients undergoing general surgery. We will obtain informed consent, and all information will be collected and examined anonymously. The findings of this research will be released in appropriate scientific publications.
