RESUMO

INTRODUCTION: Existing research has shown that intimate partner violence (IPV) may hinder maternal access to healthcare services, thereby affecting maternal and child health. However, current studies have ignored whether emotional intimate partner violence (EV) could negatively affect maternal healthcare use. This study aims to evaluate the impact of invisible IPV on maternal healthcare utilization in Pakistan. METHODS: We analyzed nationally representative data from the Pakistan Demographic and Health Survey database from 2012-2013 and 2017-2018. Exposure to physical intimate partner violence (PV) and EV was the primary predictor. Based on women's last birth records, outcomes included three binary variables indicating whether women had inadequate antenatal care (ANC) visits, non-institutional delivery, and lack of postnatal health check-ups. A logistic regression model was established on weighted samples. RESULTS: Exposure to EV during pregnancy was significantly associated with having inadequate ANC visits (aOR = 2.16, 95% CI: 1.06 to 4.38, p = 0.033) and non-institutional delivery (aOR = 2.24, 95% CI: 1.41 to 3.57, p = 0.001). Lifetime exposure to EV was associated with increased risks of inadequate ANC visits (aOR = 1.48, 95% CI: 1.00 to 2.19, p = 0.049). Lifetime exposure to low-scale physical intimate partner violence (LSPV) (adjusted OR (aOR) = 1.73, 95% CI: 1.29 to 2.31, p < 0.001) was associated with increased risks of having no postnatal health check-ups. CONCLUSIONS: Pregnant women who experienced EV and LSPV are at greater risk of missing maternal healthcare, even if the violence occurred before pregnancy. Therefore, in countries with high levels of IPV, early screening for invisible violence needs to be integrated into policy development, and healthcare providers need to be trained to identify EV and LSPV.

RESUMO

BACKGROUND: The mental and emotional health of persons diagnosed with cancer is frequently affected. The acceptance and commitment therapy (ACT) is one of the psychological interventions that has proven successful in easing these psychological symptoms and enhancing cancer patients' psychological well-being. METHODS: A two-arm randomized controlled trial study was utilized, 30 eligible clients with colorectal cancer were chosen randomly and were given ACT therapy at a 1:1 ratio. ACT was delivered in six sessions for 3 weeks, followed by 3 months follow-up. RESULTS: The table shows a statistically significant increase in the mean scores of the mental health and its flourishing level among the study group than those of the control group. Cognitive impairment was significantly decreased among the study group than for those in the control group. CONCLUSION: The ACT-based interventions may be a promising approach for improving mental health and cognitive function in cancer patients, particularly those with advanced disease.

RESUMO

Drought is one of the most important wheat production limiting factor, and can lead to severe yield losses. This study was designed to examine the effect of drought stress on wheat physiology and morphology under three different field capacities (FC) viz. 80% (control), 50% (moderate) and 30% (severe drought stress) in a diverse collection of wheat germplasm including cultivars, landraces, synthetic hexaploid and their derivatives. Traits like grain weight, thousand grain weight and biomass were reduced by 38.23%, 18.91% and 26.47% respectively at 30% FC, whereas the reduction rate for these traits at 50% FC were 19.57%, 8.88% and 18.68%. In principal component analysis (PCA), the first two components PC1 and PC2 accounted for 58.63% of the total variation and separated the cultivars and landraces from synthetic-based germplasm. Landraces showed wide range of phenotypic variations at 30% FC compared to synthetic-based germplasm and improved cultivars. However, least reduction in grain weight was observed in improved cultivars which indicated the progress in developing drought resilient cultivars. Allelic variations of the drought-related genes including TaSnRK2.9-5A, TaLTPs-11, TaLTPs-12, TaSAP-7B-, TaPPH-13, Dreb-B1 and 1fehw3 were significantly associated with the phenological traits under drought stress in all 91 wheats including 40 landraces, 9 varieties, 34 synthetic hexaploids and 8 synthetic derivatives. The favorable haplotypes of 1fehw3, Dreb-B1, TaLTPs-11 and TaLTPs-12 increased grain weight, and biomass. Our results iterated the fact that landraces could be promising source to deploy drought adaptability in wheat breeding. The study further identified drought tolerant wheat genetic resources across various backgrounds and identified favourable haplotypes of water-saving genes which should be considered to develop drought tolerant varieties.

RESUMO

Exon skipping using antisense oligonucleotides (ASOs) has recently proven to be a powerful tool for mRNA splicing modulation. Several exon-skipping ASOs have been approved to treat genetic diseases worldwide. However, a significant challenge is the difficulty in selecting an optimal sequence for exon skipping. The efficacy of ASOs is often unpredictable, because of the numerous factors involved in exon skipping. To address this gap, we have developed a computational method using machine-learning algorithms that factors in many parameters as well as experimental data to design highly effective ASOs for exon skipping. eSkip-Finder (https://eskip-finder.org) is the first web-based resource for helping researchers identify effective exon skipping ASOs. eSkip-Finder features two sections: (i) a predictor of the exon skipping efficacy of novel ASOs and (ii) a database of exon skipping ASOs. The predictor facilitates rapid analysis of a given set of exon/intron sequences and ASO lengths to identify effective ASOs for exon skipping based on a machine learning model trained by experimental data. We confirmed that predictions correlated well with in vitro skipping efficacy of sequences that were not included in the training data. The database enables users to search for ASOs using queries such as gene name, species, and exon number.

RESUMO

Hemoglobinopathies, including α- and ß-thalassemias and sickle cell disease, are among the most widely disseminated hereditary blood disorders worldwide. Bangladesh is considered a hotspot for hemoglobinopathies, and these diseases cause a significant health concern in the country. However, the country has a dearth of knowledge on the molecular etiology and carrier frequency of thalassemias, primarily due to a lack of diagnostic facilities, limited access to information, and the absence of efficient screening programs. This study sought to investigate the spectrum of mutations underlying hemoglobinopathies in Bangladesh. We developed a set of polymerase chain reaction (PCR)-based techniques to detect mutations in α- and ß-globin genes. We recruited 63 index subjects with previously diagnosed thalassemia. Along with age- and sex-matched control subjects, we assessed several hematological and serum indices and genotyped them using our PCR-based methods. We identified that parental consanguinity was associated with the occurrence of these hemoglobinopathies. Our PCR-based genotyping assays identified 23 HBB genotypes, with the codons 41/42 (-TTCT) (HBB: c.126_129delCTTT) mutation leading the spectrum. We also observed the presence of cooccurring HBA conditions, of which the participants were not aware. All index participants in this study were on iron chelation therapies, yet we found they had very high serum ferritin (SF) levels, indicating inefficient management of the individuals undergoing such treatments. Overall, this study provides essential information on the hemoglobinopathy mutation spectrum in Bangladesh and highlights the need for nationwide screening programs and an integrated policy for diagnosing and managing individuals with hemoglobinopathies.

RESUMO

Heavy metal toxicity has become a global health burden, exerting various physiological effects on aquatic animals and humans. Zebrafish (Danio rerio) has emerged as a real-time model system for toxicological study. We previously reported the effects of arsenic on the embryonic development of zebrafish. The current study aimed to get deep insights into the toxic effects of another heavy metal, lead, on the early embryonic development of wild-caught zebrafish. We exposed freshly collected zebrafish embryos to different lead concentrations and studied different developmental and morphological changes using an inverted microscope. In a separate experiment, embryos were exposed to a combination of lead and arsenic to evaluate the combined effects of the elements. Lead concentration of as low as 0.25 mM resulted in developmental and morphological abnormalities in the zebrafish embryos. Exposure to different concentrations (0.25 mM, 0.5 mM, and 0.75 mM) caused a higher mortality rate of the embryos. Besides, an increased rate of arrested hatching, irregularities in size and shape of the yolk sac, deformed otic vesicle, and body curvature were observed in a dose-dependent manner. Lead exposure also resulted in reduced heart rate and severe pericardial edema. The combined effect of minimum concentrations of lead and arsenic that causes toxicity individually (0.25 mM and 1.0 mM, respectively) revealed a more severe effect than the individual treatments. This study's findings explain the association of heavy metal exposure with an increased rate of miscarriage/abortion incidences in highly polluted areas assisting in proper management and creating public awareness.

RESUMO

The prevalent convolutional neural network (CNN)-based image denoising methods extract features of images to restore the clean ground truth, achieving high denoising accuracy. However, these methods may ignore the underlying distribution of clean images, inducing distortions or artifacts in denoising results. This paper proposes a new perspective to treat image denoising as a distribution learning and disentangling task. Since the noisy image distribution can be viewed as a joint distribution of clean images and noise, the denoised images can be obtained via manipulating the latent representations to the clean counterpart. This paper also provides a distribution-learning-based denoising framework. Following this framework, we present an invertible denoising network, FDN, without any assumptions on either clean or noise distributions, as well as a distribution disentanglement method. FDN learns the distribution of noisy images, which is different from the previous CNN-based discriminative mapping. Experimental results demonstrate FDN's capacity to remove synthetic additive white Gaussian noise (AWGN) on both category-specific and remote sensing images. Furthermore, the performance of FDN surpasses that of previously published methods in real image denoising with fewer parameters and faster speed.

RESUMO

Coronaviruses have marked their significant emergence since the twenty-first century with the outbreaks of three out of the seven existing human coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2003, Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2019. These viruses have not only acquired large-scale transmission during their specified outbreak period, but cases of MERS-CoV still remain active, although there is only limited transmission. While, on the other hand, SARS-CoV-2 continues to remain a rising threat to global public health. The recent novel coronavirus, SARS-CoV-2, responsible for the ongoing coronavirus disease 2019 (COVID-19), emerged during December 2019 in Wuhan, China, and has repeatedly raised questions about its characteristic variability. Despite belonging to the same family, SARS-CoV-2 has proven to be quite difficult to control and contain in terms of transmissibility, leading to around 19.8 million reported cases and more than 730,000 deaths of individuals worldwide. Here, we discuss how SARS-CoV-2 differs from its two other related human coronaviruses in terms of genome composition, site of infection, and transmissibility, among several other notable aspects-all indicating to the possibility that it is these variations in addition to other unknowns that are contributing to this virus' differing deadly pattern.

RESUMO

PURPOSE: Seroprevalence surveys from different countries have reported SARS CoV-2 antibodies below 20% even in the most adversely affected areas and herd immunity cannot be predicted till more than half of the population gets the disease. The purpose of this survey was to estimate the magnitude of community-based spread of the infection, associated immunity, and the future prospects and proximity to a 'herd community'. METHODS: The study was undertaken as a cluster randomized, cross-sectional countrywide survey. This largest community-based seroprevalence data of SARS-CoV-2 were collected between 15th and 31st July, 2020 from seven randomly selected cities belonging to the three most populous provinces of Pakistan. The FDA approved kit of ROCHE was used for detection of SARS-CoV-2 antibodies. RESULTS: Serum samples of 15,390 participants were tested for SARS CoV-2 antibodies with an overall seroprevalence of 42.4%. The seroprevalence ranged from 31.1% to 48.1% in different cities with the highest in Punjab province (44.5%). In univariable analysis, the odds of seropositivity was higher in men compared to women (OR: 1.10, 95% CI: 1.01-1.19, P < 0.05). In multivariable analysis, the risk of being seropositive was lower (OR 0.72, 95% CI: 0.60-0.87, P < 0.01) in younger group (≤ 20 years) than in those aged above 60 years. CONCLUSION: The study concluded that despite a reasonable seroprevalence, the country is yet to reach the base minimum of estimations for herd immunity. The durability of immunity though debated at the moment, has shown an evidenced informed shift towards longer side.

RESUMO

BACKGROUND: Lack of hygiene and sanitation causes significant disease, disability and death. Majority of diarrheal diseases are related to hygiene and drinking water. Hand washing with soap after toilet use and before eating reduces these risks significantly. METHODS: This report is based on a behavior change project in the rural community setting (union council Nahqi), Peshawar, Pakistan aimed to improve hygiene- and sanitation-related behavior. A pre-intervention survey was conducted at household level (n = 958), followed by a structured behavior change communication program with motivational and educational material and key health messages for three months. Lastly, an end-line survey was conducted measuring change in practice domains. RESULTS: All the domains of hygiene and sanitation showed statistically significant improvement (11-59% P < 0.001), including handwashing before meals (28.2%), before cooking (54.1%), before child feeding (21.2%), after defecation (30.6%); tooth brushing twice daily (7.3%); nail clipping at least weekly (16.3%); bathing daily (11.3%); change of clothing twice weekly (24.7%); covering the water containers (59.3%) and house orderliness (30.6%). CONCLUSION: The findings conclude that a behavior change communication program that is in accord with community needs, level of their understanding, beliefs and sociocultural norms is well received for positive behavior change.

RESUMO

Green synthesis of nanomaterials is advancing due to its ease of synthesis, inexpensiveness, nontoxicity and renewability. In the present study, an eco-friendly biogenic method was developed for the green synthesis of nickel oxide nanoparticles (NiONPs) using phytochemically rich Berberis balochistanica stem (BBS) extract. The BBS extract was rich in phenolics, flavonoids and berberine. These phytochemicals successfully reduced and stabilised the NiNO3 (green) into NiONPs (greenish-gray). BBS-NiONPs were confirmed by using UV-visible spectroscopy (peak at 305 nm), X-ray diffraction (size of 31.44 nm), Fourier transform infrared spectroscopy (identified -OH group and Ni-O formation), energy dispersive spectroscopy (showed specified elemental nature) and scanning electron microscopy (showed rhombohedral agglomerated shape). BBS-NiONPs were exposed to multiple in vitro bioactivities to ascertain their beneficial biological applications. They exhibited strong antioxidant activities: total antioxidant capacity (64.77%) and 2, 2-diphenyl-1-picrylhydrazyl (71.48%); and cytotoxic potential: Brine shrimp cytotoxicity assay with IC50 (10.40 µg/mL). BBS-NiONPs restricted the bacterial and fungal pathogenic growths at 1000, 500 and 100 µg/mL. Additionally, BBS-NiONPs showed stimulatory efficacy by enhancing seed germination rate and seedling growth at 31.25 and 62.5 µg/mL. In aggregate, BBS extract has a potent antioxidant activity which makes the green biosynthesis of NiONPs easy, economical and safe. The biochemical potential of BBS-NiONPs can be useful in various biomedical and agricultural fields.

RESUMO

α-Thalassemia (α-thal) is assumed to be very prevalent in Bangladesh. We aimed to assess the prevalence of the disease in the country and provide a model for α-thal newborn screening in Bangladesh. We collected umbilical cord blood (UCB) samples from 413 unrelated newborns in Bangladesh. Demographic information, blood indices, osmotic fragility, serum iron (Fe), and zinc (Zn) levels were evaluated for all the subjects. All subjects underwent a polymerase chain reaction (PCR)-based diagnosis for α-thal status, followed by a multiplex gap-PCR-based identification of the deletion type present. Sixty-seven subjects had at least one α-thal deletion (16.22%). We observed that -α3.7 (rightward), - -SEA (Southeast Asian), -α4.2 (leftward), - -MED (Mediterranean) and - -THAI (Thailand) deletions were the most common α-globin deletions present in the country, with the -α3.7 (n = 37) and - -SEA (n = 18) being most prevalent. The osmotic fragility test (OFT) could predict the presence of α-thal deletions with over 98.0% sensitivity. Complete UCB count analysis revealed significant differences between healthy subjects and subjects with α-thal deletions. Although the iron level was almost the same (108.0 vs. 105.7 µg/dL), a reduced level of Zn (98.6 vs. 71.8 µg/dL, p < 0.01) was observed in the cord blood-derived serum of the subjects with α-thal deletions. Moreover, parental age at the time of delivery, gestational period, and birth weight was lower in the subjects with α-thal deletions. This study provides partial information on the epidemiology of α-thal in Bangladesh and describes a model for α-thal newborn screening in the country.

RESUMO

BACKGROUND: Pakistan has recently observed a significant growth in public health education programmes. Little is known about the structure of these programmes nor whether they are adequately responsive to national health system needs. AIMS: We reviewed existing public health degree programmes in Pakistan along with an exploration of the national public health market and health system needs. METHODS: A mixed-methods study was conducted between January 2015 and March 2016. Seventeen public health degree programmes were reviewed for programmatic and instructional attributes. Thirteen key-informant interviews were conducted to explore health system needs and challenges related to public health workforce. RESULTS: We found substantial variation in public health academic programmes in terms of offered courses, credit hours, number of faculty and tuition costs. About 70% of public health degree programmes were generic (i.e. with no specific concentration track) and only 18% offered practicums. Overall median tuition cost in 2016 was US$ 10 350. During key-informant interviews, emerged themes for challenges included lack of practical public health skills, limited knowledge of latest theoretical principles, poor communication skills and insufficient IT orientation. Identified themes about knowledge and skills areas to address future public health challenges of Pakistan included system thinking mind set, healthcare IT skills, and leadership and management skills. CONCLUSIONS: Public health education in Pakistan falls short of meeting current national challenges. Pakistan needs a national public health accreditation body for regulating education, harmonizing global standards to local context and developing relevant career pathways.

RESUMO

BACKGROUND: Public Private Partnership has been experimented as an approach in Pakistan in 2005 and in eighteen districts of Khyber Pakhtunkhwa including Abbottabad in 2011, to improve delivery of maternal and child health services. This study was conducted to assess the utilization of maternal and child health services before and after implementation of Public Private Partnership in district Abbottabad. METHODS: A cross sectional study was conducted in district Abbottabad from July to December 2014. Study included all the 53 basic health units, outsourced to People's Primary Healthcare Initiative in 2011. Data related to selected maternal and child health services indicators (family planning services, antenatal and post-natal care, safe delivery, tetanus toxoid vaccination of pregnant women and child immunization), before and after the introduction of Public Private Partnership, was collected. Significance tests (t-test) was applied and p-value <0.05 was taken as significant. RESULTS: Marked improvement was observed in vaccination of target children (127%) and women (42%), respectively. Similarly, utilization of family planning services, antenatal and postnatal care increased by 60%, 9% and 38%, respectively. Public Private Partnership had significant effect on postnatal visits (p<0.001), family planning services (p<0.001), women vaccinated with tetanus toxoid (p<0.001) and children vaccinated in Expanded Program of Immunization (p=0.003). CONCLUSIONS: Public Private Partnership improved the utilization of maternal and child health services, particularly family planning services and maternal & child immunization. The partnership may be scaled up and extended, for an improved coverage of maternal and child health services.

RESUMO

Dysferlinopathies refer to a spectrum of muscular dystrophies that cause progressive muscle weakness and degeneration. They are caused by mutations in the DYSF gene, which encodes the dysferlin protein that is crucial for repairing muscle membranes. This review delves into the clinical spectra of dysferlinopathies, their molecular mechanisms, and the spectrum of emerging therapeutic strategies. We examine the phenotypic heterogeneity of dysferlinopathies, highlighting the incomplete understanding of genotype-phenotype correlations and discussing the implications of various DYSF mutations. In addition, we explore the potential of symptomatic, pharmacological, molecular, and genetic therapies in mitigating the disease's progression. We also consider the roles of diet and metabolism in managing dysferlinopathies, as well as the impact of clinical trials on treatment paradigms. Furthermore, we examine the utility of animal models in elucidating disease mechanisms. By culminating the complexities inherent in dysferlinopathies, this write up emphasizes the need for multidisciplinary approaches, precision medicine, and extensive collaboration in research and clinical trial design to advance our understanding and treatment of these challenging disorders.

RESUMO

Most existing graph neural networks (GNNs) learn node embeddings using the framework of message passing and aggregation. Such GNNs are incapable of learning relative positions between graph nodes within a graph. To empower GNNs with the awareness of node positions, some nodes are set as anchors. Then, using the distances from a node to the anchors, GNNs can infer relative positions between nodes. However, position-aware GNNs (P-GNNs) arbitrarily select anchors, leading to compromising position awareness and feature extraction. To eliminate this compromise, we demonstrate that selecting evenly distributed and asymmetric anchors is essential. On the other hand, we show that choosing anchors that can aggregate embeddings of all the nodes within a graph is NP-complete. Therefore, devising efficient optimal algorithms in a deterministic approach is practically not feasible. To ensure position awareness and bypass NP-completeness, we propose position-sensing GNNs (PSGNNs), learning how to choose anchors in a backpropagatable fashion. Experiments verify the effectiveness of PSGNNs against state-of-the-art GNNs, substantially improving performance on various synthetic and real-world graph datasets while enjoying stable scalability. Specifically, PSGNNs on average boost area under the curve (AUC) more than 14% for pairwise node classification and 18% for link prediction over the existing state-of-the-art position-aware methods. Our source code is publicly available at: https://github.com/ZhenyueQin/PSGNN.

RESUMO

The current study details a sequence of sequential reactions for synthesizing bis-indole-based triazine bearing thiazole derivatives. Several steps were involved in the synthesis of bis-indole-based triazine bearing thiazole derivative. The synthetic reactions were monitored via thin-layer chromatography (TLC). Synthesized compounds were characterized using various spectroscopic techniques, including 1H NMR, 13C NMR, and HR-EIMS. The inhibitory activity against urease enzyme of these synthesized compounds was compared with that of thiourea, a standard drug (IC50 = 9.30 ± 0.20 µM). A range of inhibitory potencies were observed for the synthesized compounds, ranging from moderate to excellent, as follows (IC50 = 5.10 ± 0.40 µM to 29.80 ± 0.20 µM). Analyzing the structure-activity relationship (SAR) provided insight into the results, showing that different substituents had different effects on aromatic rings. Several compounds displayed outstanding inhibitory properties (among those tested were 1, 2, 4, 5, and 6 with IC50 = 6.30 ± 0.80, 5.10 ± 0.40, 5.90 ± 0.50, 8.20 ± 0.10, 8.90 ± 0.60 µM, respectively). Anti-urease evaluation of all the synthesized derivatives was conducted in which the selected compounds have shown remarkable potency compared with the standard drug thiourea (IC50 = 9.30 ± 0.20 µM). Molecular docking analysis was carried out for investigating the better binding sites and distance of the derivatives. Moreover, the drug-like properties were explored by the ADME attributes of the synthesized analogs.

RESUMO

Pakistan is one of two countries globally still endemic for poliovirus. While increasing immunization coverage is a concern, providing equitable access to care is also a priority, especially for conflict-affected populations. Recognizing these challenges, Naunehal, an integrated model of maternal, newborn, and child health (MNCH), immunization, and nutrition services delivered through community mobilization, mobile outreach, and private-sector engagement was implemented in conflict-affected union councils (UCs) with high poliovirus transmission, including Kharotabad 1(Quetta, Balochistan) and Bakhmal Ahmedzai (Lakki Marwat, Khyber Pakhtunkhwa). A quasi-experimental pre-post-design was used to assess the impact of the interventions implemented between April 2021 and April 2022, with a baseline and an endline survey. For each of the intervention UCs, a separate, matched-control UC was identified. At endline, the proportion of fully immunized children increased significantly from 27.5% to 51.0% in intervention UCs with a difference-in-difference (DiD) estimate of 13.6%. The proportion of zero-dose children and non-recipients of routine immunization (NR-RI) children decreased from 31.6% to 0.9% and from 31.9% to 3.4%, respectively, with a significant decrease in the latter group. Scaling up and assessing the adoption and feasibility of integrated interventions to improve immunization coverage can inform policymakers of the viability of such services in such contexts.

RESUMO

AIM: The purpose of this study is to assess the effect of a distance education training program on nurse interns' readiness for distance education and their perceptions of lifelong learning. DESIGN: A quasi-experimental research approach with one-group, pre/post-test was used. METHODS: The study used a quasi-experimental research approach and was carried out at Damanhour University's Faculty of Nursing. A study was carried out on 345 interns' students. All nursing interns enrolled in the 2020-2021 internship training year. The researchers employed a program that contained a distance education readiness assessment as well as a questionnaire about the perceived advantages of lifelong learning. RESULTS: The majority (99.7%) of nurse interns were highly ready for distance education, whereas only 0.3 percent were moderately ready following the training program implementation immediately. In comparison to pre-training, the majority (91.9%) of them were somewhat ready for distance education, while just 7.2 percent were highly prepared. Furthermore, the majority (97.1%) of them had high total skills of distance education after implementation of the training program by 3 months, and 95.4 percent had high total skills of learning immediately after the training program, whereas 26.1% of nurse interns had high total skills before the training program, at p value 0.01.

RESUMO

BACKGROUND: The eradication of poliovirus and improving routine immunization (RI) coverage rates present significant challenges in Pakistan. There is a need for interventions that focus on strengthening community engagement to improve routine immunization coverage. Our primary objective is to assess the impact of an integrated strategy designed to enhance community engagement and maternal and child health immunization campaigns on immunization coverage in Pakistan's high-risk union councils of polio-endemic districts. METHOD: We implemented an integrated approach for routine immunization and maternal and child health in the polio-endemic district of Pakistan. This approach involved setting up health camps and actively engaging and mobilizing the local community. An independent team conducted surveys at three key points: baseline, midline, and endline, to evaluate immunization coverage among children under the age of five. The primary outcome measures for the study were coverage of OPV, IPV, and changes in the proportion of unvaccinated and fully vaccinated children. To select clusters and eligible households in each cluster, we utilized a 30 × 15 cluster sampling technique. Multivariable associations between socio-demographic factors and changes in the proportion of fully vaccinated children at the UC level were assessed using hierarchical linear regression models. RESULTS: A total of 256,946 children under the age of five (122,950 at baseline and 133,996 at endline) were enrolled in the study. By the endline, full immunization coverage had increased to 60% or more in all three study areas compared to the baseline. Additionally, there was a significant increase in the coverage of both OPV and IPV across all three provinces at the endline. The full immunization rates were assessed on three levels of the framework: the distal, intermediate (access and environment), and proximal level (camp attendance and effectiveness). At the distal level, on multivariate analysis, family size was found to be a significant predictor of change in immunity within the families (ß = 0.68; p ≤ 0.0001). At the intermediate level, the likelihood of full immunization decreased with the decrease in knowledge about vaccination (ß = -0.38; p = 0.002), knowledge about polio vaccine (ß = -0.25; p = 0.011), and knowledge about IPV (ß = -0.06; p = 0.546). Perceived obstacles to vaccination were fear of adverse events (ß = -0.4; p ≤ 0.0001) and lack of education (ß = 0.23; p = 0.031), which were found to be significant in bivariate and multivariate analyses. At the proximal level, community mobilization (ß = 0.26; p = 0.008) and attendance at health camp (ß = 0.21; p ≤ 0.0001) were found to enhance full immunization coverage. On the other hand, the most prominent reason for not attending health camp included no need to attend the health camp as the child was not ill (ß = -0.13; p = 0.008). CONCLUSIONS: This study found that community mobilization and attendance at health camps significantly enhanced full immunization coverage. The findings highlight the importance of community engagement and targeted interventions in improving immunization coverage and addressing barriers to healthcare seeking.
