Objectives

Does a simulation-based training intervention with an artificial intelligence (AI) navigation system improve their clinical bronchoscopy performance? And can the AIs outcome measures be used to evaluate clinical performance?

Design

Pre–postintervention study.

Setting

Odense University Hospital of Southern Denmark, pulmonary endoscopy suite.

Participants

Nine bronchoscopists (4 experienced, >500 bronchoscopies and 5 intermediates, 10–500 bronchoscopies).

Primary outcome measures

Diagnostic completeness (DC), structured progress (SP), procedure time (PT) and procedure efficiency (DC/PT).

Results

The primary outcome measures showed no statistically significant difference between the pre- and postintervention bronchoscopies DC: 53% versus 59%, p=0.16, SP: 29% versus 32%, p=0.35 and PT: 219 s versus 181 s, p=0.22. The experienced outperformed the intermediates regarding DC: 73% versus 43%, p

Conclusions

DC, SP and PT showed no statistically significant difference after a simulation-based training intervention. DC, SP and procedure efficiency differentiated between experienced and intermediate bronchoscopists and can be used to evaluate clinical bronchoscopy performance.

In an era where digital communication accelerates the global spread of false narratives, understanding how misinformation and disinformation propagate, especially during crises such as the COVID-19 pandemic, is vital to public health and policy. To delve into the diffusion mechanisms of misinformation (unintentionally false information) and disinformation (intentionally false information), we introduce a novel enhanced agent-based model (ABM) that integrates psycho-social factors and communication networks, which are elements often overlooked in traditional equation-based models (EBMs). We assess the two distinct techniques (ABMs and EBMs) through the lens of six classical SEIRS-class models (S susceptible, E exposed, I infected, R recovered). Beside the enhanced ABM, we also develop a simple ABM to emulate the EBM structure. We compare the ABMs with the EBMs over their entire parameter ranges in a total of 11110 experiments. Results show an overall weak equivalence between the two types of models, even if, under certain conditions, the outcomes of the EBMs and ABMs are similar. Furthermore, we evaluate the two model types by fitting them to real-world infodemic data on vaccine acceptance over 36 weeks using a multi-objective optimization procedure. The enhanced ABM shows an exceptionally better fit to real-world data (Pearson’s correlation coefficient ρ = 0.872 and normalized root mean of square error NRMSE  = 0.055) than the EBM (ρ=−0.067, NRMSE  = 0.418) and the simple ABM (ρ=0.391, NRMSE  = 0.103). These findings underscore the critical role of model structure in capturing infodemic dynamics, and advocate for the use of ABMs when psycho-social influences and network interactions are central to the phenomenon.

Sociodemographic and clinical factors associated with non-adherence to stroke medication: an analytical, multi-hospital cross-sectional survey in Punjab, Pakistan

Por: Arshed · M. · Gillani · A. H. · Kiran · M. · Ashraf · W. · Virk · M. K. S. · Umer · M. F. · Samkari · J. A. · Arshad · H. · Qamer · S. · Shahbaz · S. · Howard · N. · Fang · Y. — Noviembre 13th 2025 at 12:41
Objective

Studying issues related to stroke medication non-adherence is essential for secondary prevention of stroke. This study aimed to identify the prevalence of medication non-adherence and risk factors among stroke survivors. The reasons behind this are that some patients may not follow stroke medication plans, and potential ways to help patients adhere better to medication plans.

Design

This study employed a cross-sectional patient survey.

Setting

The study was conducted in 20 public and private healthcare facilities in a resource-constrained setting, in Punjab, the largest province of Pakistan.

Participants

We included 6538 stroke survivors aged 21–75 years with at least a 6 month history of stroke who were prescribed one or more anti-stroke medications and met the inclusion criteria.

Primary outcome measures

The main outcome was medication non-adherence, measured by the Self-Efficacy for Appropriate Medication Scale (SEAMS) and self-reported pill count. Descriptive statistics were used to summarise study variables. chi-square (²)/Fisher’s exact test and independent t-test/ANOVA were employed. A generalised linear model (logit model using multivariable logistic regression shows that several factors are associated with medication non-adherence and adherence. Odds ratio (OR) plots were generated using Seaborn and Matplotlib.

Results

Non-adherence based on pill counts was 49.7%, while the mean SEAMS score (31.3±7.7) showed moderate self-reported adherence. After adjusting for age, gender, marital status, education, income, health insurance, smoking status, comorbidities, stroke type, disease duration, blood pressure control, number of medications, dosing frequency, physiotherapy continuation, perceived side effects and doctor-patient satisfaction, we found that female gender (vs male: AOR 0.31, 95% CI 0.27 to 0.35), lower income (10k–25k PKR vs >100k PKR: AOR 0.31, 95% CI 0.23 to 0.41; 26k–50k PKR vs >100k PKR: AOR 0.57, 95% CI 0.47 to 0.68), primary/secondary education (vs postgraduate: AOR 0.74, 95% CI 0.64 to 0.87), controlled BP (vs uncontrolled: AOR 0.66, 95% CI 0.59 to 0.73), longer disease duration (≥5 years vs

Conclusion

This study addresses the significant issue of medication non-adherence in stroke patients in Pakistan, reflecting global patterns yet remaining under-explored locally. It emphasises the critical role of adherence in managing chronic conditions such as stroke, where consistent use of preventive therapies is vital for reducing recurrence and improving outcomes. While the non-adherence rates are consistent with global trends, there is a notable lack of observational studies and epidemiological data in the Pakistani context. Our findings support a comprehensive approach to enhance medication adherence, taking into account the complex connections among social, behavioural and clinical factors. It also highlights the importance of maintaining detailed records to monitor adherence trends, identify high-risk groups and inform targeted public health interventions.

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. — Octubre 9th 2025 at 10:17
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.

Threshold-based compliance with diabetic ketoacidosis management protocols and its association with inpatient mortality: a retrospective single-centre study in a tertiary hospital in Karachi, Pakistan

Por: Fatima · S. · Rehman · N. · Hashmi · M. · Khan · A. · Shahzaib · M. · Akram · M. T. · Arshad · A. — Julio 30th 2025 at 11:57
Objectives

The aim of this study was to evaluate protocol adherence and its impact on inpatient mortality in patients with diabetic ketoacidosis (DKA) at a tertiary hospital in Karachi. The major hypothesis was that adherence to the DKA protocol reduces inpatient mortality.

Design

This was a retrospective cohort study.

Setting

The study was conducted at the Aga Khan University Hospital (AKUH), Karachi, a tertiary care hospital in Pakistan.

Participants

The study included patients diagnosed with DKA and admitted to AKUH from 2017 to 2021. Eligibility criteria included patients aged 18 and older, excluding those with incomplete records or referred to other hospitals.

Primary and secondary outcome measures

The primary outcome was inpatient mortality. The analysis included Cox proportional hazards regression. Secondary outcome measures included predictors of mortality such as hypertension, intubation, tachycardia and elevated creatinine levels.

Results

Non-compliance with the DKA protocol (

Conclusions

Adherence to the DKA protocol is crucial for reducing inpatient mortality and improving outcomes, especially in low- and middle-income countries. Ensuring at least 70% compliance is vital. Recommendations include continuous training for healthcare providers, adequate staffing and resource optimisation. Future research should focus on interventions to boost compliance and explore other factors affecting protocol adherence to further enhance patient care.
