What happens when private general practitioners receive incentivisation offers from pharmaceutical sales representatives? A qualitative study in Pakistan.

OBJECTIVES: Pharmaceutical incentivisation of physicians for profit maximisation is a well-documented health system challenge. This study examined general practitioners' (GPs) reactions to pharmaceutical incentivisation offers in one region in Pakistan. METHODS: We used the Standardised Pharmaceutical Sales Representative (SPSR) method and qualitative interviews with GPs. SPSRs were field researchers representing mock pharmaceutical companies who recorded their observations of 267 GPs' responses to pharmaceutical incentivisation offers. We triangulated SPSR data using qualitative interviews with a subset of the same GPs to gather information about how they interpreted different interaction outcomes. RESULTS: We found four major outcomes for GPs being offered incentives by pharmaceutical companies for prescribing medications. GPs might agree to make incentivisation deals, reject incentivisation offers, disallow PSRs to access them, or remain indeterminate with no clear indication of acceptance or rejection of incentivisation offers. GPs rejecting SPSRs' incentivisation offers indicated having active commitments to other pharmaceutical companies, not being able to work with unheard-of companies, and asking SPSRs to return later. CONCLUSIONS: The GP-pharmaceutical sales representative interaction that centres on profit-maximisation is complex as offers to engage in prescribing for mutual financial benefit are not taken up immediately. The SPSR method helps understand the extent of distortion of practices impacted by incentivisation. Such an understanding can support the development of strategies to control unethical behaviours.

Predictors of neurocognition outcomes in children and young people with primary brain tumor presenting to tertiary care hospitals of Karachi, Pakistan: a prospective cohort study.

INTRODUCTION: Primary brain tumors are a common cause of morbidity and mortality in children and young people (CYP) globally. Impaired neurocognitive function is a potential severe consequence in primary brain tumor (PBT) survivors. There are no in-depth studies from low- and middle-income countries (LMICs) to inform management and follow-up. The research questions of this study were as follows: Are the sociodemographic factors (lower age of CYP, female gender, low socioeconomic status, low parental education), disease-related factors (high grade of tumor, presence of seizures, presence of hydrocephalous), and treatment-related factors (adjuvant therapy, no surgical intervention, post-treatment seizures, placement of shunts) associated with decline in neurcognition outcomes 12 months post-treatment in CYP with PBTs? METHODS: A prospective cohort study was conducted from November 2020 to July 2023 at the Aga Khan University Hospital and Jinnah Postgraduate Medical Centre, tertiary care hospitals in Karachi, Pakistan. All CYP aged 5 to 21 years with a newly diagnosed PBTs were eligible. The neurocognition assessment was undertaken by a psychologist at two points, i.e., pre-treatment and at 12 months post-treatment using validated tools. The verbal intelligence was assessed by Slosson Intelligence tool, revised 3rd edition (SIT-R3), perceptual reasoning by Raven's Progressive Matrices (RPM), and the Processing Speed Index by Wechsler Intelligence Scale (WISC V) and Wechsler Adult Intelligence Scale (WAIS-IV). The data were analyzed by STATA version 12 software. Generalized estimating equation (GEE) was used to determine the factors associated with the mean change in 12 months post-treatment verbal and non-verbal neurocognition scores. Unadjusted and adjusted beta coefficients with their 95% confidence intervals were reported. RESULTS: A total of 48 CYPs with PBTs were enrolled, 23 (48%) of them were lost to follow-up and 10 (21%) died. The remaining 25 (52%) were reassessed 12 months after treatment. On multivariable analysis, a significant decline in verbal intelligence scores at 12 months was predicted by post-treatment seizures beta = - 20.8 (95% CI, - 38.2, - 3.4), mothers having no formal educational status and lower household monthly income. Similarly, a significant decline in perceptual reasoning scores was also predicted by post-treatment seizures beta = - 10.7 (95% CI, - 20.6, - 0.8), mothers having no formal education and having lower household monthly income. Worsening of processing speed scores at 12 months post-treatment were predicted by tumor histology, post-treatment seizures beta = - 33.9 (95% CI, - 47.7, - 20.0), lower educational status of the mother, and having lower household monthly. However, an improvement was seen in processing speed scores after surgical tumor resection. CONCLUSION: In this novel study, the post-treatment mean change in verbal and non-verbal neurocognition scores was associated with sociodemographic, tumor, and treatment factors. These findings may have potential implications for targeted early psychological screening of higher risk CYP with PBTs. Identification of these predictors may serve as a foundation for developing more cost-effective treatment thereby alleviating the burden of neurocognitive morbidity. However to establish generalizability, future research should prioritize larger-scale, multicountry studies. (Trial registration: ClinicalTrials.gov Identifier: NCT05709522).

Assessing the Feasibility of a Multifaceted Intervention Package for Improving Respiratory Health of Textile Workers: Findings From the MultiTex Pilot Study in Karachi, Pakistan.

We piloted the development and implementation of a multifaceted intervention package for improving respiratory health among textile workers using a pre-post design at six mills in Karachi. The intervention, implemented following a baseline survey (n = 498), included health and safety training of workers and managers, promotion of cotton dust control measures, and the provision of facemasks. Follow-up surveys were conducted at 1, 6, and 12 months post-intervention. Knowledge, attitude, and practice (KAP) scores and respiratory symptoms were assessed through a questionnaire and spirometry was conducted. The intervention was provided to 230 workers and led to an improvement in KAP scores that was more likely among workers with a higher educational status, spinners, smokers, those with a permanent employment status, working in morning shifts, and with ⩾5 years of textile experience. We found the intervention acceptable and feasible in these textile mills henceforth, trials are required to determine its effectiveness.

"If the food is finished after my brother eats then we (girls) sleep hungry." Food insecurity and dietary diversity among slum-dwelling adolescent girls and boys in Pakistan: A mixed methods study.

To explore gender differences in food insecurity (FI) and minimum dietary diversity (MDD) among adolescent girls and boys in a slum community in Karachi, we employed an explanatory sequential mixed methods study that included a survey of 391 girls and boys of 10-19 years of age and followed by semi-structured interviews of eight purposely selected food insecure adolescents. Survey data was analyzed by Cox proportional algorithm and adjusted prevalence ratios (APR) with 95% confidence intervals (CI) were estimated for associated factors of FI and thematic analysis was undertaken for qualitative work. Meta inferences for mixed methods study were drawn by joint display analysis of survey results juxtaposed to qualitative findings. Overall, FI among adolescents was prevalent (46.5%) which was not different between boys (52.7%) and girls (47.3%) (APR 0.8, (95% CI 0.6, 1.2); p-value-0.4). MDD (5/10 food groups consumed) was achieved by only 23.0% and it was also not different between boys (25.1%) and girls (20.9%) (p-value-0.3). The survey found no significant difference in FI and MDD between boys and girls however, qualitative findings provided insight into the cultural practices at mealtimes that prefer boys. Qualitative results contrasted the survey results and revealed the increased vulnerability of girls towards FI and low MDD compared to boys due to gender norms.

Association between maternal experiences of intimate partner violence and child stunting: a secondary analysis of the Demographic Health Surveys of four South Asian countries.

OBJECTIVES: To determine the association between maternal exposure to intimate partner violence (IPV) and child stunting using the Demographic Health Survey (DHS) data comparing four South Asian countries. DESIGN: A secondary analysis. SETTING: Data from the seventh round of the DHS data of four South Asian countries; Pakistan, Nepal, India and Maldives. PARTICIPANTS: Married women of reproductive age (15-49 years) from each household were randomly selected, having at least one child less than 5 years of age for whom all anthropometric measures were available. OUTCOME MEASURE: The exposure variable was maternal IPV including, sexual violence, physical violence or both. The outcome variable was moderate or severe stunting, measured based on the height-for-age Z-score of children aged 6-59 months old . Multiple Cox proportional regression analyses were used separately on each country's data to determine the association between maternal IPV and child stunting. RESULTS: The prevalence of IPV among women ranged from 10.17% in the Maldives to 31% in India. The burden of child stunting was the lowest in the Maldives at 14.04% and the highest in Pakistan at 35.86%. The number of severely stunted children was the highest in Pakistan (16.60%), followed by India (14.79%). In India, children whose mothers were exposed to IPV showed a 7% increase in the prevalence of moderate to severe child stunting (OR 1.07; 95% CI 1.01 to 1.14). Additionally, in Nepal, severe stunting was strongly associated with the prevalence of physical IPV (OR 1.66; 95% CI 1.01 to 2.87). CONCLUSION: Our study findings suggest that maternal exposure to IPV is associated with child stunting. Further research investigating the relationship between IPV and child outcomes using improved and advanced statistical analyses can provide substantial evidence to enhance public awareness and potentially reduce the burden of child stunting in South Asian countries.

Clinical and psychosocial factors associated with quality of life in patients with head and neck cancer: an analytical cross-sectional study from a lower-middle-income country.

INTRODUCTION: The disease course of head and neck (H&N) cancer can severely impair patients' quality of life (QoL). In Pakistan, a South Asian lower-middle-income country (LMIC), psychosocial factors may impact QoL. We aimed to assess QoL and associated factors amongst patients with H&N cancer in Pakistan. METHODS: An analytical cross-sectional study was conducted amongst adult (≥ 18 years) patients with H&N cancer who were ≥ 4 weeks post-initiation of treatment. The survey assessed QoL (European Organization for Research and Treatment of Cancer Quality of Life Questionnaires), anxiety and depression (Hospital Anxiety and Depression Scale), and social support (Enriched Social Support Instrument). Multivariable linear regression was performed for analysis. RESULTS: A total of 250 patients (mean age: 51.6 years) were included. The majority of patients were married (87%) and living with multigenerational/extended family households (53%). On multivariable linear regression, ongoing cancer treatment (beta coefficient: -13.93), having a tracheostomy (-10.02), and receiving adjuvant chemoradiotherapy (-8.17) were significantly associated with poorer global QoL. Additionally, poorer QoL was associated with depression (-24.37) and anxiety (-13.34). However, having more household family members was associated with better global QoL (0.34). CONCLUSION: The QoL of patients with H&N cancer in Pakistan is affected by both the nature of cancer treatment as well as sociocultural factors such the number of household family members. Given that poorer QoL is associated with worse mental health outcomes, there is a need to develop and implement psychosocial interventions to improve the QoL of patients with H&N cancer in Pakistan, particularly during active treatment.

Feasibility of a peer-supported, WhatsApp-assisted, lifestyle modification intervention for weight reduction among adults in an urban slum of Karachi, Pakistan: a mixed-methods, single-group, pretest-post-test, quasi-experimental study.

OBJECTIVES: This pilot study assessed whether a peer-supported, WhatsApp-assisted lifestyle modification intervention for weight reduction is feasible to execute a definitive trial. DESIGN: A mixed-methods, single group, pretest and post-test, quasi-experimental study. SETTING: Azam Basti, an urban slum in Karachi, Pakistan. PARTICIPANTS: Fifty participants (males and females aged 20-60) with a body mass index of >23 kg/m2, along with their nominated peers from the same family. INTERVENTION: Using motivational interviewing techniques, a trained nutritionist delivered the lifestyle modification intervention to the participants and peers for 3 days after the baseline assessment and then once monthly for 1 year. The intervention was delivered in groups using WhatsApp voice calls. The education sessions mainly focused on dietary modifications, physical activity advice and peer-support assignments to achieve a 5% wt loss from the participant's initial body weight. OUTCOMES: The feasibility measures included screening, recruitment, retention and monthly interview response rates. At 1 year, in-depth interviews (IDIs) with participants and peers were conducted to explore the facilitators, barriers, acceptability and experiences of the intervention. Changes in weight, calorie intake/day and calorie expenditure/day were also assessed. RESULTS: The recruitment and retention rates were 32% (n=50/156) and 78% (n=39/50), respectively, while the response rate for monthly interviews ranged between 66% (n=33) and 94% (n=47). The mean weight loss at 1 year was 2.2 kg, and the reduction in mean calorie intake was 386 kcal/day. There were no changes in the mean calorie expenditure. During the IDIs, participants and peers reported intervention via WhatsApp and peer support as convenient, flexible and supportive. CONCLUSIONS: The quantitative and qualitative findings of the current pilot study support the scale-up of this work with minor modifications to the screening method as well as close monitoring and motivational interviewing to improve adherence in terms of physical activity. TRIAL REGISTRATION NUMBER: NCT05928338.

Exploring the relationship between intimate partner violence during pregnancy and stillbirths.

INTRODUCTION: The relationship between intimate partner violence (IPV) in pregnancy and stillbirths is poorly understood. We aimed to determine if there was any association between stillbirths and IPV during pregnancy. METHODS: A community-based, matched, case-control study was conducted in 2014, nested within the Maternal and Newborn Health Registry of the Global Network for Women's and Children's Health Research in Pakistan. Using a WHO questionnaire, IPV in pregnancy was ascertained from 256 cases (women with stillbirths) and 539 controls (women with live births), individually matched on parity. Multivariable conditional logistic regression analysis assessed the association of IPV in pregnancy ending in stillbirths compared to those with live births. RESULTS: The effect of physical and psychological IPV was modified by maternal age. Among women 25-34 years old with stillbirths, the odds of experiencing physical IPV in pregnancy were four times greater than those with live births, after controlling for confounders [odds ratio 4.1 (95% CI: 1.5, 11.2)]. A negative association was observed between psychological IPV in pregnancy and stillbirths among women younger than 25 years, and no association was observed between sexual IPV during pregnancy and stillbirths. CONCLUSION: Study results show that women 25-34 years of age with stillbirths were four times more likely to experience physical IPV during pregnancy. Further studies replicating the effect modification of IPV by maternal age are warranted.

Effectiveness of inactivated COVID-19 vaccines against SARS-CoV-2 infections among healthcare personnel in Pakistan: a test-negative case-control study.

OBJECTIVE: During the COVID-19 pandemic, several vaccines that were efficacious in randomised controlled trials were authorised for mass vaccination. In developing countries, inactivated vaccines were widely administered. While inactivated vaccines have been deemed effective in reducing disease severity, for healthcare personnel (HCP), effectiveness against SARS-CoV-2 infections is essential to reduce the risk to vulnerable patients and ensure a stable healthcare workforce. There are limited studies examining inactivated vaccines' effectiveness against SARS-CoV-2 variants of concern (VOCs) in real-world settings. We estimated the effectiveness of inactivated vaccines (BBIBP-CorV and CoronaVac) against reverse transcription PCR (RT-PCR)-confirmed SARS-CoV-2 infections among HCP in the setting of emerging SARS-CoV-2 VOCs in Pakistan. DESIGN: A retrospective matched, test-negative case-control analysis using existing data from an Employee Health database on HCP at a large, private healthcare system in Pakistan. PARTICIPANTS: 4599 HCP were tested between 1 April and 30 September 2021. Each case (PCR positive) was matched to two to six controls (PCR negative) by the date of the RT-PCR test (±7 days) to reduce bias. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was vaccine effectiveness (VE) against SARS-CoV-2 infection. The secondary outcome was VE against symptomatic SARS-CoV-2 infection. Per cent VE was calculated using (1-OR)*100, with the OR of getting a PCR-confirmed SARS-COV-2 infection estimated using conditional logistic regression, after adjusting for age, gender, work area and history of SARS-CoV-2 infection. RESULTS: Inactivated vaccines were ineffective against SARS-CoV-2 infections after receiving the first dose (VE 17%, 95% CI -10, 39; p=0.261). They showed modest effectiveness ≥14 days after the second dose against SARS-CoV-2 infections (VE 30%, 95% CI 7, 48; p=0.015) and symptomatic SARS-CoV-2 infections (VE 33%, 95% CI 6, 52; p=0.002). CONCLUSIONS: Inactivated vaccines show modest effectiveness against SARS-CoV-2 infections in the setting of emerging VOCs. This builds a strong case for boosters and/or additional vaccination.

Psychosocial factors influencing quality of life in patients with primary brain tumors in Pakistan: an analytical cross-sectional study.

OBJECTIVE: Despite quality of life (QoL) being recognized as an important outcome in neuro-oncology, there is a lack of research from Pakistan where sociocultural differences may influence QoL. This study aimed to measure the QoL in patients with primary brain tumors (PBTs) and assess its association with mental health outcomes and social support. RESULTS: Our study included a total of 250 patients, with a median age of 42 years (range 33-54 years). The commonest brain tumors were glioma (46.8%) and meningioma (21.2). The mean global QoL of the sample was 75.73 ± 14.9. The majority of patients had high social support (97.6%) and were not depressed (90%) or anxious (91.6%). On multivariable linear regression, global QoL was inversely associated with no or low income (beta coefficients: -8.75 to -11.84), having hypertension (-5.53), currently using a urine catheter (-13.55), having low social support (-28.16) suffering from mild (-15.31) or symptomatic (-23.84) depression, or mild anxiety (-13.22).

Factors affecting well-being in brain tumor patients: An LMIC perspective.

Introduction: Brain tumor is a devastating and often fatal diagnosis; quality of life and patient well-being are important goals of treatment. This study addresses the gap in culture-specific literature exploring the needs and coping strategies of brain tumor patients within an LMIC setting. Methodology: A qualitative approach was undertaken using an exploratory descriptive study design. In-depth interviews were conducted to capture the perspective of 250 brain tumor patients at a private tertiary center followed by extensive content analysis to identify major themes and sub-themes across responses. Results: The analysis identified three major themes: (i) Factors affecting the lives of brain tumor survivors (BTSs) and their impact (ii) What works to improve QoL according to the survivors' perspectives, and (iii) Coping tactics & fostering healthy relationships. The need for financial navigation strategies improved patient-physician relationships, and reinforcing positive coping strategies were emphasized. Conclusion: In our population, family support and spiritual connection played an important role in helping patients mitigate the psychosocial burden of illness. However, financial concerns were pervasive and need to be addressed for better overall well-being.

Association of the BB genotype of the ABO gene with the risk of acute myocardial infarction in hospital-based study.

Objectives: The ABO gene locus has been identified to be associated with myocardial infarction in patients with coronary heart disease. The primary focus of this hospital-based study was to explore the relationship of ABO blood groups and ABO genotypes with acute myocardial infarction (AMI) in Karachi, Pakistan. Methods: In a comparative cross-sectional study, an equal number of adult AMI patients and healthy controls (n=275 in each group; age range 30-70 years, both males and females) were recruited from the Aga Khan University and NICVD, Karachi, with informed consent. The blood samples were analyzed for ABO blood groups and other biomarkers. PCR followed by RFLP techniques were employed for determining the ABO genotypes. Multinomial regression was used to evaluate the association of genotypes with the risk of AMI. Results: Thirteen different combinations of ABO genotypes were observed while the O2O2 and A2A2 genotypes were not detected. No significant association based on the distribution of blood groups A, B, O and AB among AMI patients and healthy individuals was observed. The odds of AMI were 3.32 times in subjects with BB genotype as compared to subjects with OO genotypes after adjustment of age, gender, body mass index, heart rate, total cholesterol, and waist circumference [AOR (95% CI) =3.32 (1.36-8.08), p-value =0.008]. Conclusion: Our hospital-based study indicates that ABO genotype BB was significantly associated with the risk of AMI. This harmful effect of the BB genotype could have a possible relationship with AMI's development in the Pakistani population.

Follow-up household assessment for child unintentional injuries two years after the intervention: A community-based study from Karachi, Pakistan.

BACKGROUND: Unintentional childhood injuries are a growing public health concern, and the home is the most common location for non-fatal injuries in children less than 5 years of age. This study describes the long-term effects of two injury prevention educational interventions for caregivers-an educational pamphlet and an in-home tutorial guide-by comparing the change in the prevalence of home injury hazards before and after the interventions. METHODS: This was a pre- (June and July 2010) and post-study with short-term follow-up (November-December 2010) and long-term follow-up (November 2012- January 2013). Neighborhood one included households that received only educational pamphlets after completing a baseline assessment; neighborhood two included households that received an in-home tutorial guide after completing the baseline assessment and receiving the educational pamphlet. The main outcome of this study was the reduction in home injury hazards for children under 5 years of age. RESULTS: A total of 312 households participated in the long-term phase to compare the effect of the interventions. Between the short-term to long-term follow-up, injury hazards significantly reduced in neighborhood two compared to neighborhood one. These included fall hazards (walker use) (IRR 0.24 [95% CI 0.08-0.71]), drowning hazards (open bucket of water in the courtyard and uncovered water pool) (IRR 0.45 [95% CI 0.85-0.98] and IRR 0.46 [95% CI 0.76-0.94]), burn hazards (iron, water heater within reach of child) (IRR 0.56 [95% CI 0.33-0.78] and IRR 0.58 [95% CI 0.32-0.91]), poisoning hazards (shampoo/soap and medicine within reach of child) (IRR 0.53 [95% CI 0.44-0.77] and IRR 0.7 [95% CI 0.44-0.98]) and breakable objects within reach of child (IRR 0.62 [95% CI: 0.39-0.99]). CONCLUSION: An injury prevention tutorial to caretakers of children supplemented with pamphlets could significantly decrease the incidence of falls, drowning, burns, poisoning, and cut injury hazards for children under 5 years of age in their homes in a low-resource setting. This intervention has the potential to be integrated in existing public health programs, such as Lady Health Visitors (LHVs), to disseminate injury prevention information in routine home health visits.

Impact of a multifaceted intervention on physicians' knowledge, attitudes and practices in relation to pharmaceutical incentivisation: protocol for a randomised control trial.

INTRODUCTION: In settings where the private sector constitutes a larger part of the health system, profit-gathering can take primacy over patients' well-being. In their interactions with pharmaceutical companies, private general practitioners (GPs) can experience the conflict of interest (COI), a situation whereby the impartiality of GPs' professional decision making may be influenced by secondary interests such as financial gains from prescribing specific pharmaceutical brands. METHODS AND ANALYSIS: This study is a randomised controlled trial to assess the impact of a multifaceted intervention on GPs' medical practice. The study sample consists of 419 registered GPs who own/work in private clinics and will be randomly assigned to intervention and control groups. The intervention group GPs will be exposed to emotive and educational seminars on medical ethics, whereas control group GPs will be given seminars on general medical topics. The primary outcome measure will be GPs' prescribing practices, whereas the secondary outcome measures will be their knowledge and attitudes regarding COI that arises from pharmaceutical incentivisation. In addition to a novel standardised pharmaceutical representatives (SPSR) method, in which field researchers will simulate pharmaceutical marketing with GPs, presurvey and postsurvey, and qualitative interviewing will be performed to collect data on GPs' knowledge, attitudes and practices in relation to COI linked with pharmaceutical incentives. Univariate and multivariate statistical analyses will be performed to measure a change in GPs' knowledge, attitudes and practices, while qualitative analysis will add to our understanding of the quantitative SPSR data. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Pakistan National Bioethics Committee (# 4-87/NBC-582/21/1364), the Aga Khan University (# 2020-4759-1129) and the London School of Hygiene and Tropical Medicine (# 26506). We will release results within 6-9 months of the study's completion. TRIAL REGISTRATION NUMBER: ISRCTN12294839.

COVID-19 vaccine acceptance and hesitancy among the general population of Pakistan: a population-based survey.

OBJECTIVES: This study aims to determine the COVID-19 vaccination coverage and the factors associated with vaccine acceptance and hesitancy in the general population of Pakistan. SETTING: This population-based study covers all major areas of Pakistan, including Sindh, Punjab, Khyber Pakhtunkhwa and Baluchistan provinces and the capital Islamabad. PARTICIPANTS: A total of 541 male and female Pakistani adults above 18 years were interviewed to determine the COVID-19 vaccination coverage and understand the factors associated with vaccine acceptance and hesitancy. OUTCOME: The outcome was COVID-19 vaccination status (not vaccinated or vaccinated). RESULTS: Of 541 participants, 227 (41.96%) were non-vaccinated and 314 (58.04%) were vaccinated. Two-thirds of the participants from both the non-vaccinated and vaccinated groups (185 (81.50%) vs 236 (75.16%), p=0.008) reside in Sindh. Nearly one-third of participants from both groups were ever infected with COVID-19 (77 (33.92%) and 90 (28.66%)). The odds of COVID-19 vaccination among the age group 34-42 years were 1.75 times higher (95% CI 1.35 to 2.09, p=0.008) than the other age groups. The odds of COVID-19 vaccination among those with COVID-19 ever-infected family members were 1.87 times higher (95% CI 1.56 to 2.34, p=0.032) than those with uninfected family members. CONCLUSIONS: Targeted interventions for subsets of populations reluctant to vaccination can improve vaccine coverage. Moreover, advocacy and explaining the public health benefits of vaccination can enhance the coverage in Pakistan.

Psychometric properties of the Urdu version of the EORTC QLQ-H&N35 (European organization for research and treatment of cancer head and neck module) quality of life tool.

BACKGROUND: We translated and validated the Urdu version of the European Organization for Research and Treatment of Cancer Quality of Life (QoL) Questionnaire's Head and Neck (H&N) Cancer Module (EORTC QLQ-H&N35) and assessed its convergent and discriminant validity by examining correlations of QoL with depression, anxiety, and resilience. METHODS: We translated the EORTC QLQ-H&N35 according to EORTC instructions. Patients at a tertiary care hospital in Pakistan completed a survey consisting of Urdu versions of EORTC QLQ-C30 (core QoL tool), QLQ-H&N35, Hospital Anxiety and Depression Scale, and Wagnild and Young Resilience Scale (RS-14). Content validity, convergent validity, discriminant validity, and reliability (using Cronbach's alpha) of the EORTC QLQ-H&N35 were assessed. RESULTS: Our sample comprised 250 patients with H&N cancer, most commonly oral (82%). The Urdu translations were comprehensible for all patients. The Cronbach alpha for QLQ-H&N35 multi-item domains ranged from 0.75 to 0.98 (acceptable to excellent), barring "Senses Problems", which was less than the generally acceptable level (0.50). The patient-reported content validity index (CVI) scores for relevance and clarity of the Urdu version of the QLQ-H&N35 were 0.93 and 0.92, respectively (both excellent). Our results revealed weak bidirectional correlations of the QLQ-H&N35 with resilience, depression, and anxiety, showing good discriminant validity. A weak-to-moderate but significant negative correlation (r: - 0.185 to - 0.613; p < 0.01) was seen between the QLQ-H&N35 and the global QoL measure of the QLQ-30. CONCLUSION: Our Urdu translation of the EORTC QLQ-H&N35 demonstrated validity comparable to previous studies, with good discriminant construct validity when measured against resilience, depression, and anxiety. An issue of concern is the poor internal consistency of the "Senses Problems" domain. Nevertheless, the Urdu translation produced in this study serves as a valid and reliable measure to measure QoL in H&N cancer in clinical or research settings in Pakistan.

Determinant of repeat revascularization within 5 years of Percutaneous Coronary Intervention at a tertiary care hospital, Karachi: A matched case-control study.

OBJECTIVE: To determine factors associated with repeat revascularization among adults aged 25 years and above within 5 years of first Percutaneous Coronary Intervention (PCI) at a tertiary care hospital. METHODS: A matched case-control study was conducted through a hospital records review. A total of 90 cases with repeat revascularization and 180 controls without repeat revascularization were included. Data was analyzed using Multiple Conditional Logistic Regression. RESULTS: The mean age was similar in cases and controls (60.05 ± 10.01 vs 62.20 ± 10.43 years) and sex (male: 77.8% vs. 76.1%). History of being an ever-smoker (40% vs. 25%), overweight (36.3% vs. 30.6%), and poor glycemic control (23.3% vs. 12.2%) were more among the cases than controls. However, obesity (53.7% vs. 44.3%) and pre-diabetes (16.1% vs. 7.8%) were more in controls compared to cases.Upon matching on the time of index PCI, the adjusted odds of ever smokers among patients with repeat revascularization was 2.47 times the odds of ever smokers among patients who did not undergo revascularization. Increasing stent diameter by 1 mm was found to reduce the risk of repeat revascularization by 51%. CONCLUSIONS: Smoking cessation and appropriate selection of stent diameter in patients undergoing revascularization can reduce the risk of repeat revascularization in the future.

Pesticides Use and Impaired Lung Function Among Male Agricultural Farmers in Rural Sindh, Pakistan.

Use of pesticides implicated in decrement in lung function, manifested as restrictive or obstructive dysfunction or both. Using comparative cross-sectional study design, authors conducted the study to determine an association of pesticide use with impairment in lung function (restrictive/obstructive pattern of lung function) among agricultural farmers. The data were collected using modified American Thoracic Society Division of Lung Disease (ATS-DLD-78A) questionnaire and spirometer measurements. Using multinomial logistic regression, the risk of both restrictive and obstructive lung dysfunction was found to be almost twice among pesticides users with each increasing year of exposure to pesticides (1.92 and 1.95, respectively) after adjusting for other covariates. There is a need for reliable monitoring and reporting procedures along with appropriate environmental policies and regulations for handling of pesticides. Interventional studies are needed where farmers could be trained on the proper use of personal protective equipment (PPE) to limit the exposure to pesticides.

Influence of intrauterine growth status on aortic intima-media thickness and aortic diameter in near-term fetuses: a comparative cross-sectional study.

Intrauterine undernutrition may lead to fetal vascular programming. We compared abdominal aortic intima-media thickness (aIMT) and aortic diameter (aD) between appropriate for gestational age (AGA) and growth-restricted fetuses (GRF). We recruited 136 singleton fetuses at 34-37 weeks of gestation from Fetal Medicine Unit of Aga Khan University Hospital, Karachi (January-November 2017). Subjects were classified as AGA (n = 102) and GRF (n = 34) using INTER-GROWTH 21st growth reference and standard ultrasound protocol. Their far- and near-wall aIMT and aD were compared after adjustment of maternal age, first-trimester body mass index, fetal gender, hypertension and hyperglycemia in pregnancy. As the severity of growth restriction increased in GRF, aIMT and aD showed an increasing and a decreasing trend, respectively. Both far- and near-wall aIMT in GRF [(adj. ß = 0.082, 95% confidence interval [CI] 0.042-0.123) and (adj. ß = 0.049, 95% CI 0.010-0.089)] were significantly greater with reference to AGA fetuses. GRF subgroup analysis into small for gestational age (SGA) fetuses and intrauterine growth restricted (IUGR) revealed highly significant difference between AGA and IUGR for far (0.142 mm, P-value < 0.001) and near-wall aIMT (0.115 mm, P-value < 0.001) and marginally significant aD difference (0.51 mm, P-value 0.05). These findings suggest that the extent of fetal aortic remodelling is influenced by the severity of growth restriction. Hence, the targeted interventions for the cardiovascular health promotion of IUGR and SGA born neonates are desirable during early childhood, particularly in set ups with high prevalence of low birth weight babies.

Spatiotemporal variation and socioeconomic factors of financial hardships of out-of-pocket health expenditure in Pakistan.

BACKGROUND: Financial hardships of out-of-pocket health expenditure (OPHE) is a growing concern for health policy makers in many low and middle-income countries. Spatiotemporal variation between Pakistan's four provinces over 2001-2015 is discussed, which would help comparing existing health services delivery and financial risk protection plans. AIMS: In this paper, we estimate financial hardship of OPHE in Pakistan. METHODS: We use the data sets of the household integrated economic surveys 2001-02, 2005-06, 2010-11 and 2015-16. We estimate OPHE share in household total and non-subsistence expenditure, catastrophic headcount at the threshold of OPHE ≥ 10% of total expenditure or OPHE ≥ 25% of non-subsistence expenditure. We estimate impoverishment of OPHE using national poverty lines. Finally, we explore socioeconomic factors of financial hardships of OPHE. RESULTS: Over the years, catastrophic headcount and impoverishment of OPHE had decreased at national level (-1.3% points) and in the provinces of Sindh (-7.8% points) and Khyber Pukhtoonkhawa (KPK), (-2.8% points). The province of KPK and the year 2005-06 witnessed the highest incidence of financial catastrophe (26.89% points) and impoverishment (4.8% points) of OPHE. Households in rural areas, in the middle and rich quintiles and those headed by a male were more likely to encounter financial catastrophe and impoverishment due to OPHE. CONCLUSION: Inter-provincial variation in financial hardships of OPHE provide aide to provincial level priority setting. The high impact of OPHE in the non-poor, in rural areas, and in KPK calls for enhanced targeting of financial risk protection plans.
