RESUMO
Objectives: Adhesion molecules, sICAM-1 and sE-selectin appear to have a major role in the pathogenesis of coronary artery disease (CAD). The focus of this study was to investigate the relationship of sICAM-1 and sE-selectin with ABO blood groups in Pakistani patients hospitalized with acute myocardial infarction (AMI). Methods: In a case-control study, 116 patients of acute myocardial infarction (AMI) and 116 healthy controls (age range for both: 30 years to 70 years; both males and females) were randomly selected from the Aga Khan University and National Institute of Cardiovascular Diseases, Karachi with informed consent. The blood samples were obtained and analyzed for ABO blood groups and serum levels of sICAM-1 and sE-selectin using kit methods. Statistical tests including independent sample t-test and Two-way ANOVA were used to study the association of these adhesion molecules with blood groups in AMI patients and healthy controls. Duration of the study was from July 2021 to June 30, 2023. Results: Mean serum levels of sICAM-1 were significantly higher in AMI patients compared to healthy controls (342±159 mg/dl vs. 227±104 mg/dl; p-value<0.001). Similarly, serum levels of sE-selectin were also significantly higher in AMI patients compared to healthy controls (53.6±26.9 mg/dl vs. 40.7± mg/dl; p-value<0.001). Moreover, mean concentrations of sICAM-1 and sE-selectin for the interaction between subject type (cases and control) and blood groups were statistically significant (p-value = 0.007 and p-value = 0.035, respectively). Conclusion: There is an association of adhesion molecules, sICAM-1 and sE-selectin with ABO blood groups in Pakistani patients hospitalized with AMI.
RESUMO
BACKGROUND: In early 2021, the 10-valent Pneumococcal conjugate vaccine (PCV10) was replaced with 13-valent (PCV13) by the federal directorate of immunization (FDI), Pakistan. We assessed the impact of a higher valent vaccine, PCV13, on the serotype distribution of nasopharyngeal carriage in rural Pakistan. METHODS: Children <2 years were randomly selected from two rural union councils of Matiari, Sindh in Pakistan between September-October,2022. Clinical, sociodemographic and vaccination histories were recorded. Nasopharyngeal swabs were collected and processed at Infectious Disease Research Laboratory, Aga Khan University, Karachi. Whole genome sequencing was performed on the culture positive isolates. RESULTS: Of the 200 children enrolled, pneumococcus was detected in 140(70 %) isolates. Majority of age-eligible children (60.1 %,110/183) received 3 PCV13 doses. PCV10 carriage declined from 13.2 %(78/590) in 2017/18 to 7.2 % (10/140) in 2022, additional PCV13 serotypes (3, 6A/6C and 19A) decreased from 18.5 %(109/590) to 11.4 %(16/140) while non-PCV13 serotypes increased from 68.3 %(403/590) to 81.4 %(114/140). There were 88.5 %(n = 124), 80.7 %(n = 113), 55.0 %(n = 77), and 46.0 %(n = 65) isolates predicted to be resistant to cotrimoxazole, penicillin(meningitis cut-off), tetracycline, and erythromycin respectively. CONCLUSION: Replacing PCV10 with PCV13 rapidly decreased prevalence of PCV13 carriage among vaccinated children in Matiari, Pakistan. Vaccine-driven selection pressure may have been responsible for the increase of non-PCV13 serotypes.
RESUMO
BACKGROUND: Women with gestational diabetes mellitus (GDM) are at a greater risk of developing type 2 diabetes mellitus (T2DM) than women without GDM. Despite this elevated risk, few trials on the prevention of T2DM among South Asian women with GDM have been reported. Therefore, this study aimed to assess the feasibility of conducting a diabetes prevention program on women with a history of GDM to inform the development of a contextually relevant definitive trial. METHODS: Using a randomized controlled trial, women with GDM (n = 180) who delivered at the study hospitals (one public and one private teaching hospital, Karachi) with fasting blood glucose levels < 120 mg/dl at 6 weeks postpartum were randomized to the intervention (n = 88) or control arms (n = 92). Women in the intervention group received individualized home-based educational sessions from trained community health workers at 0, 1, 3, 6, and 9 months. In addition, they received short text messages, prerecorded messages, and printed educational material (calendars and pamphlets) for reinforcement. The intervention was centered on equipping women with knowledge, skills, and confidence to eat a healthy diet rich in fruits, vegetables, and low-fat dairy products and perform regular physical activity based on walking and household chores to reduce weight (up to 5% of their initial body weight). Women in the control arm received standard care. The feasibility outcomes of the study included screening, recruitment, and retention rates and in-depth interviews at 6 months post-intervention to explore women's experiences with the intervention. Descriptive analysis and thematic analysis were performed. RESULTS: Of the 324 women screened during the antenatal care visits and after delivery, 255 (78.7%) were contactable 6 weeks postpartum, and 180 (70.6%) were eligible and randomized to intervention (n = 88) and control (n = 92) groups. Loss to follow-up in the intervention and control arms was 22.7% (n = 20/88) and 18.5% (n = 17/92), respectively. Women expressed satisfaction with home-based counseling and follow-up visits, text message reminders, and printed material in the form of a calendar through our qualitative interviews. CONCLUSIONS: Home-based lifestyle modification intervention augmented with text messages and printed material is feasible. However, to evaluate the intervention's effectiveness, a larger trial is warranted to assess its long-term impact on diabetes prevention. TRIAL REGISTRATION: ISRCTN, ISRCTN11387113 . Registered 5 December 2017-retrospectively registered.
RESUMO
OBJECTIVE: Disturbances in the oral mucosa is a major concern among patients undergoing chemotherapy. One of the most significant barriers in the implementation of oral care is the lack of knowledge. The aim of the study was to assess gingival and periodontal health status of chemotherapy patients before and after the provision of oral hygiene instructions. METHODS: A single group, pre-post test was conducted to assess oral health status of patients at the daycare chemotherapy, Aga Khan University Hospital, Karachi, Pakistan. Oral hygiene instructions were given with study models and leaflets. Patients were followed for 6-weeks. Oral health was assessed by using Simplified-Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Differences in indices were analyzed in STATA version-15.0 using Generalized Estimating Equation (GEE) and Wilcoxon Signed-rank test. RESULTS: Out of 74, 53 (72%) patients completed study follow-up. Improvement in the OHI-S was found in 14 (26%) patients (p-value < 0.001). GEE showed that age [adjusted OR = 1.10; 95% CI: 1.03-1.11], current chemotherapy cycle [adjusted OR = 1.19; 95% CI: 0.98-1.46], highest education level [Adjusted OR = 1.37; 95% CI: 1.08-12.7] and cancer therapy [Adjusted OR = 0.12; 95% CI: 0.24-0.55] were significantly associated with the change in OHI-S. Wilcoxon signed-rank test showed positive changes in the CPI (p-value < 0.001). CONCLUSIONS: Basic oral hygiene instructional intervention can be effective in improving the oral hygiene of chemotherapy patients. Nurses should also play a key role in providing psychological and nutritional support to patients.

BACKGROUND: Preeclampsia is one of the three leading causes of worldwide maternal mortality. Oxidative stress-mediated endothelial damage is expected to be an ultimate common mechanism in the pathophysiology of preeclampsia. The role of bioamines is also well-established in the induction of preeclampsia. This project is aimed to understand the factors which may affect the induction, progression, and aggravation of preeclampsia and oxidative stress during pregnancy. This study will explore the methylation pattern of the Catechol-O-methyltransferase gene to determine its role in the pathogenesis of preeclampsia, association of Val158Met polymorphism with a wide range of oxidative stress biomarkers, major antioxidants vitamins, and blood pressure regulating amines in preeclamptic Pakistani women. METHODS AND ANALYSIS: In this prospective case-control study, 85 preeclamptic and 85 normotensive pregnant women will be recruited in their third trimesters. DNA will be extracted from peripheral blood and Val158Met polymorphism in the Catechol-O-methyltransferase gene will be examined on PCR amplified product digested with Hin1II (NlaIII) restriction enzyme, further validated by Sanger sequencing. Methylation-sensitive PCR will also be performed. Oxidative stress biomarkers, antioxidant vitamins, bioamines, and catechol-O-methyltransferase levels will be measured by ELISA. The data will be used to correlate maternal and fetal outcomes in both groups. DISCUSSION: This study will help to identify and understand the multifactorial path and cause-effect relationship of gene polymorphism, oxidative stress biomarkers, major antioxidants vitamins, and blood pressure regulating amines in the pathogenesis and aggravation of preeclampsia in the Pakistani population. The outcome of this project will be particularly helpful in reducing the incidence of preeclampsia and further improving its management.

OBJECTIVE: To determine the survival rates of colorectal cancer (CRC) in the Pakistani population and determine the prognostic factors for survival among the CRC patients. STUDY DESIGN: Retrospective cohort study. Place and Duration of the Study: The cancer registry of the Aga Khan University Hospital, Karachi, Pakistan, from 2010 to 2016. METHODOLOGY: The abstracted data from the cancer registry was cleaned and updated regarding the vital status at the last follow-up. Survival analyses were performed using the Kaplan-Meier method. Adjusted hazard ratios (aHR) and their 95% confidence intervals (CIs) were estimated using a cox regression model to assess the prognostic factors for survival. RESULTS: The overall proportion of late-onset CRC (>50 years of age) was 55.3% and early-onset CRC (<=50 years of age) was higher than expected (45.7%). A high level of carcinoembryonic antigen (CEA) (>5 ng/ml) was associated with poor survival compared to patients with CEA levels of ≤5 ng/ml (aHR = 1.68, 95% CI = 1.04, 2.72). Patients, who experienced recurrence, showed poorer survival (aHR = 4.27, 95% CI = 2.55, 7.14). Patients, who did not undergo surgery, showed significantly poorer survival compared to those who underwent surgery (aHR = 5.53, 95% CI = 2.35, 13.03). CONCLUSION: The findings suggest that monitoring CEA levels, ensuring prompt surgical treatment and follow-up care for recurrent cases can improve survival outcomes in patients with colorectal cancer.

BACKGROUND: There are limited data available, particularly in low- and middle-income countries (LMICs), on the long-term quality of life (QoL) and family functioning of primary caregivers of children and young people (CYPs) affected by primary brain tumors (PBTs). This study aimed to assess the factors associated with the mean change in QoL and family functioning scores of primary caregivers of CYP patients with PBTs 12 months posttreatment. METHODS: This prospective cohort study enrolled CYPs aged 5-21 years with newly diagnosed PBTs and their primary caregivers. The study was carried out between November 2020 and July 2023. The primary caregivers of CYPs were recruited from two major tertiary care centers in Karachi, Pakistan. The primary caregivers QoL were assessed by the Pediatric Quality of Life Inventory (PedsQL) Family Impact Module. The assessment was undertaken by a psychologist at the time of diagnosis and 12 months posttreatment. The data were analyzed with STATA version 12. RESULTS: Forty-eight CYPs with newly diagnosed PBTs and their primary caregivers (46 mothers and 2 fathers) were enrolled. At 12 months posttreatment, 25 (52%) CYPs and their primary caregivers (mothers) were reassessed, and 23 (48%) were lost to follow-up. On multivariable analysis, a significant decrease in mothers' mean 12-month posttreatment QoL and family functioning scores was associated with CYP having posttreatment seizures (beta= -10.2; 95% CI: -18.4 to -2.0) and with the financial burden associated with the CYP's illness (beta= -0.3; 95% CI: -0.4 to -0.1). However, in those cases where CYP had higher posttreatment quality of life scores (beta = 0.4; 95% CI = 0.1, 0.6) and posttreatment higher verbal intelligence scores (beta = 0.1; 95% CI = 0.01, 0.3), the mothers' QoL and family functioning scores were significantly greater. CONCLUSION: We found a significant decrease in QoL of mothers who had a high financial burden and whose CYP had posttreatment seizures. However, those whose CYPs had higher posttreatment verbal intelligence scores and quality of life scores had significantly greater QoL scores. Identification of the factors that influence primary caregivers QoL has the potential to aid in the development of targeted strategies to alleviate stressors and improve the overall quality of life for primary caregivers and their children who are at high risk.

BACKGROUND: Rotavirus (RV) induced diarrhea led to hospitalization and mortality prior to the introduction of the rotavirus vaccine (RVV). The estimated RVV coverage was 86% in children less than one year of age in Pakistan. OBJECTIVES: To determine the difference in the number of diarrheal episodes among children who received and who did not receive RVV, along with the parental and physician's perspectives on the barriers toward RV immunization in children aged less than 1 year in Karachi, Pakistan. METHODS: A mixed-methods study design was conducted in three Primary Healthcare (PHC) private clinics located in different districts of Karachi, Pakistan. Data for RVV status and diarrheal episodes were collected, from medical records in June 2020 for children born between October 2019 to March 2020. Three In-depth Interviews (IDIs) with physicians and three focus group discussions (FGDs) with mothers were conducted for information on awareness and approach towards diarrhea, knowledge, and acceptance of RVV, and barriers towards RV immunization. RESULTS: A total of 430 infants visited the three PHC centres coded as A (n = 144), B (n = 146), and C (n = 140). The mean age of infants was 2.6 ± 0.2 months, 49.5 % were males and 87 (20.2 %) were partial/not vaccinated for RV. Reported diarrheal episodes were 104 (24.2 %), and of these 76 (73.1 %) were partially or not vaccinated, and 83 (79.8 %) were stunted. Recorded diarrhea was significantly associated with partial/not vaccinated status (p < 0.001), stunting (p < 0.001), and by PHC centre location (p < 0.001). PHC-C had the lowest percentage of reported diarrhea, stunting, and non/partially vaccinated status. Qualitative study (FGDs) showed that mothers had lack of awareness and knowledge on the prevention of diarrhea by RVV. Physicians' IDIs pointed towards a lack of sufficient training on RVV. CONCLUSION: Diarrheal episodes in infants were associated with partial or unvaccinated for RVV, low nutritional status, and areas of residence. Low levels of knowledge and awareness in caretakers and lack of training for RVV in PHC physicians were perceived as barriers in controlling diarrheal diseases.

BACKGROUND: Pakistan reports a significant burden of neonatal mortality, with infections as one of the major causes. We aim to assess the long-term impact of early infancy infections on neurodevelopmental outcomes during later childhood. METHODS: We conducted a prospective follow-up study of the cohort enrolled at the Karachi site of the Aetiology of Neonatal Infection in South Asia (ANISA) during 2019-2020. Children with a possible serious bacterial infection (based on the WHO IMCI algorithm) at early infancy were assessed for neurodevelopment at 6-9 years of age and compared with healthy controls. The Ten Questions (TQS) questionnaire, Strengths and Difficulties Questionnaire (SDQ), and Parent's Evaluation of Developmental Stage Assessment Level (PEDS: DM-AL) neurodevelopmental assessment tools, were administered and scored by the research staff who were blinded to the child's exposure status. Generalized Structural Equation Modelling (GSEM) was employed to verify relationships and associations among developmental milestones, anthropometry, and sociodemographic variables. RESULTS: A total of 398 children (241 cases and 157 controls) completed neurodevelopmental and growth assessments. Cases had a significantly higher rate of abnormal TQS scores (54.5% vs. 35.0%, p-value 0.001), greater delays in motor milestones (21.2% vs. 12.1%, p-value 0.02), lower fine motor skills (78.4 ± 1.4 vs. 83.2 ± 1.5, p-value 0.02). The receptive language skills were well-developed in both groups. According to the logistic regression model, exposure to infection during the first 59 days of life was associated with delayed TQS milestones (ß = -0.6, 95% CI -1.2,-0.04), TQS hearing domain (ß = -0.3, 95% CI: -1.2 to 0.7), PEDS: DM-AL fine motor domain (ß = -1.3, 95% CI: -4.4 to 1.7), PEDS: DM-AL receptive language development (ß = -1.1, 95% CI: -3.7 to 1.4) and child anthropometric measurements such as weight and height (ß = -0.2, 95% CI: -0.4 to 0.01 and ß = -0.2, 95% CI: -0.4 to -0.01, respectively). Early pSBI exposure was positively associated with PEDS: DM-AL self-help domain (ß = 0.6, 95% CI: -1.2 to 2.4) and SDQ-P overall score (ß = 0.02, 95% CI: -0.3 to 0.3). CONCLUSION: Children exposed to PSBI during early infancy have higher rates of abnormal development, motor delays, and lower fine motor skills during later childhood in Pakistan. Socioeconomic challenges and limited healthcare access contribute to these challenges, highlighting the need for long-term follow-ups with integrated neurodevelopment assessments.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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).

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.
