Assessment of residues from common pesticides and associated risks in Pakistan.

Pesticide residues have become an escalating concern in Pakistan, raising significant risks to both public health and the environment. This review overviews the current status of pesticide contamination in the country, with a specific focus on residue levels in relation to Maximum Residue Limits (MRLs) and a comparative analysis with regional and global counterparts. Several studies reveal that 30% to 70% of tested food products, including fruits, vegetables, and animal-derived products, especially in Punjab and Sindh, exceed established MRLs. This level of contamination is considerably higher than in neighboring countries such as India, where MRL exceedance ranges from 20 to 30%, and Bangladesh, which reports lower levels due to stricter regulatory efforts. In comparison, developed countries, including those in the European Union and the United States, report less than 5% of food samples exceeding MRLs, often falling below 1% due to stringent safety standards. The high prevalence of pesticide residues in Pakistan poses severe health risks, including neurological disorders, reproductive problems, and cancer, particularly in vulnerable groups like children and pregnant women. Key factors contributing to these elevated pesticide levels include insufficient knowledge of safe pesticide use, the unregulated application of banned or expired products, improper safety protocols, and malfunctioning equipment. A prevailing reliance on pesticides as the sole pest control method further hinders the adoption of Integrated Pest Management (IPM) strategies. In conclusion, pesticide residue levels in Pakistan are above permissible MRLs compared to regional and global standards, underscoring the need for urgent improvements in pesticide regulation, enforcement, and the promotion of sustainable pest control methods like IPM to better protect human health and the environment.

The brick kiln child workers of Pakistan.

Pakistani law recognises that no young person under the age of 18 years can enter into a valid and binding contract. In hazardous industries, such as brick kilns, none of the children working in them have any formal contract, so limiting any rights they may have. Any contract that does exist is with the child's father and will be linked to everlasting debts and constitutes a form of bondage. This paper reviews the adverse medical effects on children of such employment.

Uroflowmetry: nomograms in healthy young Pakistani men.

OBJECTIVE: To create a nomogram based on urine volume and flow of males without lower urinary tract symptoms. METHODS: The prospective, cross-sectional study was conducted at the Department of Urological Surgery and Transplantation, Jinnah Postgraduate Medical Centre, Karachi, from November 1, 2020, to October 31, 2022, and comprised healthy young males without lower urinary tract dysfunction who were recruited from the hospital as well as a large textile mill. They were asked to void on their normal desire. Uroflowmetry was done to determine maximum flow rate, average flow rate, and void volume values. A best-fit regression model was used to formulate uroflowmetry nomogram using average and maximum urine flow rate over voided volume. The sample size was calculated using PASS 2020 Power Analysis and Sample Size Software (2020). NCSS, LLC. Kaysville, Utah, USA. The database was developed on NCSS 2020 Statistical Software (2020). NCSS, LLC. Kaysville, Utah, USA for the data analysis. RESULTS: Of the 468 male subjects enrolled, data was analysed related to 432(92.3%). The mean age was 25.59±4.32 years. Mean maximum flow rate, average flow rate and void volume were 25.28±8.70mL/s, 14.77±4.79mL/s and 405.48±163.86mL, respectively. The association of age was noted with maximum flow rate (r=0.1435, p=0.004), average flow rate (r=0.1135, p=0.004) and void volume (r=0.0619, p=0.004). The best-fitted model for maximum and average flow rate was subsequently developed which was statistically significant (p<0.05). CONCLUSIONS: The nomograms developed could reliably predict the maximal flow rate in young Pakistani men.

Rescue therapy with Sofosbuvir /Velpatasvir/ Voxilaprevir in a patient infected with Hepatitis C virus multidrug resistant variant-a much needed option for DAA-treatment failures in Pakistan? A case-report.

Primary non-response to the currently available direct acting anti-viral (DAAs) in chronic hepatitis C virus (HCV) is rare and expected in approximately only 3-4% of the patients. Among the plausible explanations, HCV resistant variant may be one of the causes among the several other viral and host factors implicated in cases who do not achieve cure. Ever since the approval of licensed DAAs in 2014, focus has been mainly on high cure rates. Hence, significantly less attention has been given to the few difficult to treat cases. We present, herein, the case of a 50-year old male who had previously failed to respond to the currently available first and second-line DAA treatment and was then approved for a special treatment access programme. According to our knowledge this is the first case-report from Pakistan in favour of the physician's directive for special treatment access for HCV DAA-experienced patients.

From Diagnosis to Survivorship: How the Tumor Boards Facilitation Forum (TEFF) Shapes the Breast Cancer Journey in Pakistan.

Background: Breast cancer is a widespread and fatal disease that impacts millions of individuals globally. Pakistan has seen a notable rise in both incidence and mortality rates, ranking among the highest globally alongside the Solomon Islands. The WHO Global Breast Cancer Initiative (GBCI) strives to decrease global mortality by 2.5% annually, emphasizing the need for awareness campaigns to educate women about the disease.Purpose: Tumor boards serve as essential interdisciplinary platforms for discussing intricate cancer cases. Nevertheless, Pakistan's health care system encounters obstacles in delivering oncology care due to limited resources. In response, the Tumor Boards Facilitation Forum (TEFF) was established to support tumor boards within the public sector.TEFF actively promotes cancer awareness and education during Pinktober through diverse initiatives. Among these is the Self-Breast Examination workshop for students, which educates them on self-examination techniques and the significance of prompt action in identifying breast cancer symptoms. Additionally, TEFF organizes yoga activities for health care professionals, advocating for holistic well-being. Collaborating with non-profit organizations like Shine Humanity, TEFF hosts awareness camps and coordinates a scarf donation drive for cancer survivors. Furthermore, TEFF arranges breast cancer awareness walks and encourages fundraising through charity events.Conclusion: In summary, breast cancer presents a significant challenge in Pakistan, necessitating immediate action through initiatives like GBCI and TEFF to raise awareness, enhance early detection, and provide comprehensive care. These efforts promote community engagement, foster connections among survivors, and empower individuals. By uniting our efforts, we can reduce the incidence of breast cancer, improve patient outcomes, and ensure comprehensive care for all affected individuals. This article aims to underscore the crucial role of tumor boards in Pakistan in enhancing awareness and education among women regarding breast cancer.

Expanding the genetic spectrum of hereditary motor sensory neuropathies in Pakistan.

BACKGROUND: Hereditary motor and sensory neuropathy (HMSN) refers to a group of inherited progressive peripheral neuropathies characterized by reduced nerve conduction velocity with chronic segmental demyelination and/or axonal degeneration. HMSN is highly clinically and genetically heterogeneous with multiple inheritance patterns and phenotypic overlap with other inherited neuropathies and neurodegenerative diseases. Due to this high complexity and genetic heterogeneity, this study aimed to elucidate the genetic causes of HMSN in Pakistani families using Whole Exome Sequencing (WES) for variant identification and Sanger sequencing for validation and segregation analysis, facilitating accurate clinical diagnosis. METHODS: Families from Khyber Pakhtunkhwa with at least two members showing HMSN symptoms, who had not previously undergone genetic analysis, were included. Referrals for genetic investigations were based on clinical features suggestive of HMSN by local neurologists. WES was performed on affected individuals from each family, with Sanger sequencing used to validate and analyze the segregation of identified variants among family members. Clinical data including age of onset were assessed for variability among affected individuals, and the success rate of genetic diagnosis was compared with existing literature using proportional differences and Cohen's h. RESULTS: WES identified homozygous pathogenic variants in GDAP1 (c.310 + 4 A > G, p.?), SETX (c.5948_5949del, p.(Asn1984Profs*30), IGHMBP2 (c.1591 C > A, p.(Pro531Thr) and NARS1 (c.1633 C > T, p.(Arg545Cys) as causative for HMSN in five out of nine families, consistent with an autosomal recessive inheritance pattern. Additionally, in families with HMSN, a SETX variant was found to cause cerebellar ataxia, while a NARS1 variant was linked to intellectual disability. Based on American College of Medical Genetics and Genomics criteria, the GDAP1 variant is classified as a variant of uncertain significance, while variants in SETX and IGHMBP2 are classified as pathogenic, and the NARS1 variant is classified as likely pathogenic. The age of onset ranged from 1 to 15 years (Mean = 5.13, SD = 3.61), and a genetic diagnosis was achieved in 55.56% of families with HMSN, with small effect sizes compared to previous studies. CONCLUSIONS: This study expands the molecular genetic spectrum of HMSN and HMSN plus type neuropathies in Pakistan and facilitates accurate diagnosis, genetic counseling, and clinical management for affected families.

Exploring under-five mortality disparities: a comparative analysis of rural and urban areas in Punjab-Pakistan, using Multiple Indicator Cluster Survey data.

OBJECTIVES: Child health is a social and economic development indicator. Pakistan is one of the countries with a high rate of under-five mortality. This research aims to examine several demographic, geographical, socioeconomic, health-related, and environmental factors related to under-five mortality in both rural and urban areas of Punjab, Pakistan. STUDY DESIGN: This is a cross-sectional study. METHODS: We used data from the Multiple Indicator Cluster Survey 2017-18 of children aged between 0 and 59 months (n = 39,024), steered by the Punjab Bureau of Statistics. Children who died before reaching the age of five were considered as outcome variables. The bivariate relationship of the outcome variable with each socio-economic, demographic, health-seeking, and environmental variable is estimated with a P-value of <0.01. We used logistic regression analysis separately. Inclusive descriptive statistics were used for the detailed analysis, i.e., compare means, cross-tabulations, independent sample t-tests, and comparison across rural-urban areas. RESULTS: Results showed that in the mother-level variables, mother education plays a substantial role in reducing mortality; the higher the level of education, the lower the mortality rate. CONCLUSION: The study revealed that improving drinking water sources, such as tap and bottled water, can reduce the incidence of mortality, particularly in low-income households. Therefore, interventions targeting children are likely to be most effective for reducing the under-five mortality rate in Pakistan.

Associations between C-reactive protein and individual symptoms of depression in a lower-middle income country.

BACKGROUND: Data on associations between inflammation and depressive symptoms largely originate from high income population settings, despite the greatest disease burden in major depressive disorder being attributed to populations in lower-middle income countries (LMICs). AIMS: We assessed the prevalence of low-grade inflammation in adults with treatment-resistant depression (TRD) in Pakistan, an LMIC, and investigated associations between peripheral C-reactive protein (CRP) levels and depressive symptoms. METHOD: This is a secondary analysis of two randomised controlled trials investigating adjunctive immunomodulatory agents (minocycline and simvastatin) for Pakistani adults with TRD (n = 191). Logistic regression models were built to assess the relationship between pre-treatment CRP (≥ or <3 mg/L) and individual depressive symptoms measured using the Hamilton Depression Rating Scale. Descriptive statistics and regression were used to assess treatment response for inflammation-associated symptoms. RESULTS: High plasma CRP (≥3 mg/L) was detected in 87% (n = 146) of participants. Early night insomnia (odds ratio 2.33, 95% CI 1.16-5.25), early morning waking (odds ratio 2.65, 95% CI 1.29-6.38) and psychic anxiety (odds ratio 3.79, 95% CI 1.39-21.7) were positively associated, while gastrointestinal (odds ratio 0.38, 95% CI 0.14-0.86) and general somatic symptoms (odds ratio 0.34, 95% CI 0.14-0.74) were negatively associated with inflammation. Minocycline, but not simvastatin, improved symptoms positively associated with inflammation. CONCLUSIONS: The prevalence of inflammation in this LMIC sample with TRD was higher than that reported in high income countries. Insomnia and anxiety symptoms may represent possible targets for personalised treatment with immunomodulatory agents in people with elevated CRP. These findings require replication in independent clinical samples.

Aflatoxin B1 in compound feed and feed ingredients from Khyber Pakhtunkhwa.

A large-scale study was conducted to explore AFB1 contamination in feed samples using Thin Layer Chromatography, following an AOAC protocol. Samples were identified which were not compliant with the maximum limits for AFB1 as regulated in the United States and Pakistan. Of a total of 923 samples, 51 samples (5.5%) were not compliant according to Pakistan and 267 (28.9%) were not compliant with US-FDA standards. The overall prevalence of non-compliant samples of compound feed was 26.2% (n = 117) according to US-FDA standards, while none of the samples were non-compliant according to Pakistan standards. Among feed ingredients, the overall prevalence of non-compliant samples was 10.7% (n = 51) and 31.4% (n = 150) according to Pakistan and USFDA standards, respectively. Non-compliant feed with respect to AFB1 contamination was highly prevalent in Khyber Pakhtunkhwa, posing a serious threat to production performance and animals health.

Assessing Awareness, Attitude, and Practices of Breast Cancer Screening and Prevention Among General Public and Physicians in Pakistan: A Nation With the Highest Breast Cancer Incidence in Asia.

Introduction: Breast cancer is a global health challenge with significant mortality, affecting millions worldwide. The current study is aimed at evaluating awareness and practices related to breast cancer screening, prevention, and treatment among the general public and physicians in Lahore, Pakistan, which has a significant incidence of breast cancer. Methodology: The current study adopted a cross-sectional study design conducted in Lahore, Pakistan, between March and August 2023, among 404 participants from the general public and 240 physicians. Data collection and evaluation involved the use of validated questionnaires, and both descriptive and inferential statistics were performed using SPSS Version 25. Result: In Lahore, Pakistan, breast cancer awareness among the public was low, with 80.2% unaware of its global prevalence, 65.3% believing not everyone is at risk, and only 42.1% recognizing symptoms. Females showed greater awareness (OR: 1.020, CI: 0.617-1.686, p = 0.002) and positive attitudes (OR: 2.711, CI: 1.478-6.478, p = 0.045), while the 18-29 age group had higher odds of positive practices (OR: 4.317, CI: 2.678-5.956, p = 0.004). Educational attainment significantly influences knowledge and attitudes. Only 13.9% practiced self-examination. Among physicians, 88.8% were confident in screenings, but patient fear (42.9%) and financial barriers (79.2%) hindered action. Physicians with FCPS qualifications had higher odds of awareness (OR: 1.550, CI: 1.130-2.117, p = 0.007), attitudes (OR: 1.500, CI: 1.050-2.150, p = 0.025), and practices (OR: 1.470, CI: 1.070-2.017, p = 0.020). Those with 11-20 years of experience also showed better awareness (OR: 1.400, CI: 1.050-1.868, p = 0.022) and attitudes (OR: 1.450, CI: 1.045-2.018, p = 0.029). Conclusion: In conclusion, breast cancer awareness among the general public is limited, highlighting the need for tailored education programs. Although most physicians show high awareness, challenges in patient communication and barriers, such as fear and financial constraints, must be addressed to improve screening uptake. These findings emphasize the importance of targeted interventions to enhance public awareness, screening practices, and physician-patient communication.

Unraveling the impact of high arsenic, fluoride and microbial population in community tubewell water around coal mines in a semiarid region: Insight from health hazards, and geographic information systems.

High arsenic (As), fluoride (F-), and microbial pathogens coexist in semiarid conditions afflicting > 240 million people worldwide including Pakistan. Groundwater quality has declined due to geogenic and manmade activities providing suitable ground for ubiquity, bioavailability, and toxicity of contaminants. We tested the health hazard, distribution, and apportionment of As, F-, and microbes in groundwater around coal mines in Quetta, Pakistan. The range of As, and F- concentrations in groundwater were 0.2-16.6 µg/L, 0.4-18.5 mg/L. Both, As and F- correlate with high HCO3-, pH, Na+, SO42-, Fe, and Mn, and negatively with Ca2+ water. The coalfield showed many folds higher As 15.8-28.5 µg/L, and F- 10.8-34.5 mg/L compared to groundwater-wells. Geochemical phases revealed saturation of groundwater with calcite, dolomite, fluorite, gypsum, and undersaturation with halite-mirabilite, and arsenopyrite minerals. The positive matrix factorization (PMF) model assessed five-factor solutions: geogenic, industrial, coal mining, sulfide & fluoride-bearing mineral-dissolution, and agriculture pollution delivered As, F-, and microbial contamination. About 24.6 % and 64.4 % of groundwater samples exceeded the WHO guidelines of As 10 µg/L, F- 1.5 mg/L. The carcinogenicity, and non-carcinogenicity of As, and F- were higher in children than adults. Therefore, health hazards in children are of great concern in achieving sustainable management goals.

Leading report regarding the molecular epidemiology of Taenia hydatigena from Pakistan and global overview of the genetic diversity and population structure of the parasite.

Cysticercosis, caused by larval stage of Taenia (T.) hydatigena is a disease of veterinary concern which causes major economic losses in livestock sector globally. Although livestock is the most productive part of Pakistan's economy, the epidemiological prevalence and genetic diversity of T. hydatigena has not been studied in great detail. Current study was undertaken for the estimation of the prevalence and genetic diversity of T. hydatigena among the goats and sheep of Multan in South Punjab, Pakistan. A PCR protocol targeting the cytochrome c oxidase subunit 1 (cox1) gene of T. hydatigena revealed an overall prevalence of 31.33 % among the small ruminants with higher prevalence in females (40.86 %) and older age group of >3-≤5 years (40.74 %). A total of 30 isolates were sequenced for partial mitochondrial cox1 gene which yielded 12 haplotypes with a haplotype diversity of 0.798 ± 0.68 and nucleotide diversity of 0.0046 ± 0.00183. A star like configuration was demonstrated in the haplotype network with a centrally positioned haplotype. Neutrality indices like Tajima's D and Fu's Fs were also biased towards negativity, a characteristic which suggests an expanding parasitic population. Moreover, the genetic diversity of T. hydatigena was also computed for the partial cox1 gene sequences available on GenBank, NCBI. A total of 415 sequences were retrieved out of which 142 haplotypes were identified having a haplotype diversity of 0.9150 ± 0.012 coupled with a nucleotide diversity of 0.00830 ± 0.00043. The haplotype profile of T. hydatigena population displayed an absence of a central haplotype, however, considerable genetic variation was ascertained. All the populations except Africa had a high haplotype diversity (>0.9), however, high Fst values were observed for a few populations which elucidated limited gene flow among the populations of Central/East Asia, Middle East, Europe and South Asia.

Characterization of meningitis-causing bacteria, with focus on genomic and pangenomic study of multi-drug resistant Streptococcus pneumoniae from cerebrospinal fluid.

Streptococcus pneumoniae is a major cause of meningitis in under developed countries with low vaccination rates and high antibiotic resistance. This study aimed to analyze 83 suspected meningitis patients in Karachi for the detection of S. pneumoniae followed by its whole genome sequencing and Pan Genome analysis. Out of the 83 samples collected, 33 samples with altered physical (turbidity), cytological (white blood cell count) and biochemical (total protein and total glucose concentrations) parameters indicated potential meningitis cases, while these parameters were within normal healthy ranges in remaining 50 samples. Latex particle agglutination (LPA) was performed on the 33 samples, revealing 20 positive cases of bacterial meningitis. The PCR and culturing methods revealed 5 S. pneumoniae isolates. Antibiotic susceptibility tests showed that one S. pneumoniae strain was resistant to erythromycin, levofloxacin, and tetracycline. Whole-genome sequencing of this resistant strain was performed and S. pneumoniae was confirmed with MLST analysis, while it had > 2.3 Mb genome and a single repUS43 plasmid. In CARD analysis, the strain had tet(M), ermB, RlmA(II), patB, pmrA, and patA ARGs, which could provide resistance against tetracycline, macrolide, fluoroquinolone, and glycopeptide antibiotics. Phylogenetic analysis revealed that the isolate was closely related to strains from Hungary and the USA. Pan-genome analysis with 144 genome assemblies from NCBI database showed that 1101 non-redundant core genes were shared between all strains. This study gives valuable understanding into the prevalence and characterization of meningitis-causing bacteria in Karachi, Pakistan  with prime focus on multi-drug resistant S. pneumoniae.

Gender Differences in Perception of Neurosurgery as a Career Choice in Pakistan: A Nationwide Cross-Sectional Survey.

BACKGROUND: A low neurosurgeon-to-patient ratio persists to be a problem in many developing nations including Pakistan. Concurrent gender disparities further exacerbate the challenges posed by the already limited workforce. An understanding of the perceptions of neurosurgery among female early career doctors is crucial in the evolution of the field in terms of both, workforce strength and inclusivity. METHODS: A cross-sectional study was conducted across public and private medical schools of Pakistan. A close-ended self-administered questionnaire was employed to assess subject-reported challenges and perceptions regarding neurosurgery. Statistical analysis was performed using SPSS version 28, and p< 0.05 was considered significant. The influence of these perceptions on the choice of neurosurgery as a career was determined by binary logistic regression analysis. RESULTS: Of the 387 responses received from over 45 institutions across the country, 55.6% were females and 44.4% were male respondents. Compared to men, women were more likely to opt out of neurosurgery due to fear of problems with parenting (p<0.001), absence of daycare facilities (p<0.001), lack of female role models (p=0.001), fear of gender discrimination (p<0.001), and the mental (p=0.04) and physical distress (p=0.008) associated with neurosurgery. Binary logistic regression revealed that these concerns were responsible for an increased likelihood of opting out of neurosurgery among female medical students and intern doctors. CONCLUSIONS: Significant differences exist in how male and female medical students perceive neurosurgery as a career choice. Interventions including availability of day care facilities for children, creation of inclusive workplace environment, and promotion of mentorship programs catering to women can help bridge this gap and contribute to evolution of the field of neurosurgery in the developing world.

Genetic polymorphism of Duffy binding protein in Pakistan Plasmodium vivax isolates.

Plasmodium vivax Duffy binding protein (PvDBP) is crucial for erythrocyte invasion, interacting with the Duffy Antigen Receptor for Chemokines (DARC) on the erythrocyte surface. The amino-terminal cysteine-rich region II of PvDBP (PvDBPII) is a promising blood stage vaccine candidate, yet the genetic polymorphisms of this protein in global P. vivax isolates complicate the design of effective vaccines against vivax malaria. This study analyzed the genetic polymorphism of PvDBPII in Pakistan P. vivax isolates. A total of 29 single nucleotide polymorphisms (SNPs), including 22 nonsynonymous SNPs, were identified in 118 Pakistan PvDBPII. Most amino acid substitutions occurred in subdomains II and III, with six commonly observed in the global PvDBPII population. The amino acid change patterns in Pakistan PvDBPII generally mirrored those in global PvDBPII, although the frequencies of amino acid changes varied by country. Nucleotide diversity in Pakistan PvDBPII was comparable to that found in global PvDBPII. Evidence of natural selection and recombination in Pakistan PvDBPII aligned with observations in global PvDBPII. Analysis of the haplotype network of global PvDBPII revealed a complexed network of 167 haplotypes, but no geographical clustering was observed. The findings are crucial for understanding the genetic characteristics of Pakistan PvDBPII. A comprehensive analysis of nucleotide diversity and evolutionary trends in the global PvDBPII population offers valuable insights for the development of vivax malaria vaccines based on this antigen.

Systemic Lupus Erythematosus Presenting as Isolated Thrombocytopenia: A Case Report and Review of the Literature.

Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by a low platelet count, which can lead to increased bleeding and bruising. Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can affect multiple organ systems and often presents with various hematologic abnormalities, including thrombocytopenia. A 32-year-old woman presented to the emergency department with petechiae, extensive ecchymosis, rectal bleeding, generalized body aches, anorexia, and weakness. Despite showing no clinical features of SLE, laboratory findings revealed severe thrombocytopenia and anemia. Initial treatment with low-dose steroids showed no improvement, but a high-dose steroid regimen significantly increased her platelet count. Further investigations revealed elevated ANA and positive anti-dsDNA, leading to a diagnosis of isolated thrombocytopenia as the initial manifestation of SLE. The subsequent findings of elevated ANA and positive anti-dsDNA confirmed the diagnosis of SLE, with ITP as its initial manifestation. This case underscores the importance of considering underlying autoimmune diseases in patients presenting with isolated thrombocytopenia after ruling out other causes. Early recognition and appropriate treatment of autoimmune conditions like SLE can significantly improve patient outcomes, even when initial presentations are atypical.

Deep brain stimulation for post-stroke rehabilitation in Pakistan.

Stroke has a high prevalence in Pakistan, at an alarming rate of 250 per 100 000 people. Although various treatment options are available, they are not ideal for Pakistan due to their high cost, restricted availability, and time sensitivity. In 1997, the FDA-approved deep brain stimulation (DBS) for Parkinson's disease and it was first performed in Pakistan in 2014. DBS has also proved effective for restoring post-stroke mobility, according to a trial from August 2023. DBS has the potential to revolutionize post-stroke rehabilitation in Pakistan; however, further research is required into its effectiveness and its limitations must be addressed first.

The Cost-Effectiveness of Early Invasive Procedures for Acute Coronary Syndrome in Low-Income Regions: A Prospective Cohort Study in Pakistan.

Background Acute coronary syndrome (ACS) is a significant cause of mortality and morbidity globally, necessitating effective intervention strategies. Early invasive procedures such as percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are often recommended for high-risk patients. However, their cost-effectiveness in low-income regions remains uncertain, particularly in Pakistan, where healthcare resources are limited. Objective This study aims to evaluate the cost-effectiveness of early invasive procedures compared to standard care for ACS in low-income regions of Pakistan. Methods We conducted a prospective cohort study from January 1, 2021, to January 31, 2021, at four major hospitals in Pakistan: Army Cardiac Center Combined Military Hospital (CMH) Lahore, National Institute of Cardiovascular Diseases in Karachi, Lady Reading Hospital in Peshawar, and Mardan Medical Complex. The participants included 436 patients diagnosed with ACS aged 18 years or older and presenting within 24 hours of symptom onset. The patients were divided into two groups: the early invasive procedure group (n = 218) and the standard care group (n = 218). The primary outcome was the 30-day mortality rate. Secondary outcomes included recurrent myocardial infarctions, hospital readmissions, healthcare costs, and procedural complications. Data were analyzed using SPSS version 25.0 (IBM SPSS Statistics, Armonk, NY), employing descriptive statistics, chi-square tests, independent t-tests, and Kaplan-Meier survival analysis. Results The early invasive procedure group showed a mortality rate of 18 (8%) compared to 33 (15%) in the standard care group, demonstrating a significant reduction in mortality (p = 0.01). Additionally, the average healthcare cost was significantly lower in the early invasive group, with mean costs of Pakistani rupee (PKR) 187,200 (US dollar {USD} 1,200) compared to PKR 280,800 (USD 1,800) in the standard care group (p < 0.01). Recurrent myocardial infarctions occurred in 11 (5%) of the early invasive group versus 26 (12%) in the standard care group (p < 0.05). Hospital readmission rates were lower in the early invasive group, 22 (10%) compared to 39 (18%) in the standard care group (p < 0.05). Healthcare costs were significantly lower in the early invasive group, with mean costs of PKR 187,200 (USD 1,200) compared to PKR 280,800 (USD 1,800) in the standard care group (p < 0.01). Conclusion Early invasive procedures for ACS significantly improve survival rates, reduce complications, and lower healthcare costs in low-income regions of Pakistan. These findings suggest that such strategies should be considered in resource-limited settings to optimize patient outcomes and healthcare resource utilization.
