Epidemiological trends and age-period-cohort effects on cardiovascular diseases burden attributable to ambient air pollution across BRICS.

Long-term exposure to ambient air pollution raises the risk of deaths and morbidity worldwide. From 1990 to 2019, we observed the epidemiological trends and age-period-cohort effects on the cardiovascular diseases (CVD) burden attributable to ambient air pollution across Brazil, Russia, India, China, and South Africa (BRICS). The number of CVD deaths related to ambient particulate matter (PM) pollution increased nearly fivefold in China [5.0% (95% CI 4.7, 5.2)] and India [5.7% (95% CI 5.1, 6.3)] during the study period. The age-standardized CVD deaths and disability-adjusted life years (DALYs) due to ambient PM pollution significantly increased in India and China but decreased in Brazil and Russia. Due to air pollution, the relative risk (RR) of premature CVD mortality (< 70 years) was higher in Russia [RR 12.6 (95% CI 8.7, 17.30)] and India [RR 9.2 (95% CI 7.6, 11.20)]. A higher period risk (2015-2019) for CVD deaths was found in India [RR 1.4 (95% CI 1.4, 1.4)] followed by South Africa [RR 1.3 (95% CI 1.3, 1.3)]. Across the BRICS countries, the RR of CVD mortality markedly decreased from the old birth cohort to young birth cohorts. In conclusion, China and India showed an increasing trend of CVD mortality and morbidity due to ambient PM pollution and higher risk of premature CVD deaths were observed in Russia and India.

Minimum dietary diversity and associated determinants among children aged 6-23 months in Pakistan.

Pakistan is facing a high prevalence of malnutrition and Minimum Dietary Diversity (MDD) is one of the core indicators that remain below the recommended level. This study assesses MDD and its associated factors among children aged 6 to 23 months in Pakistan. The study uses a cross-sectional study using the dataset of the latest available Multiple Indicators Cluster Survey (MICS) for all provinces of Pakistan. Multistage sampling is used to select 18,699 children aged 6 to 23 months. The empirical method is the Logistic Regression Analysis and Chi-Square Test. The dataset is freely and publicly available with all identifier information removed, and no ethics approvals are required. About one-fifth (20%) of infants and young children aged 6 to 23 months had met MDD, this number varies from 17 to 29%, highest in Baluchistan and lowest in Punjab province of Pakistan. The age group (18-23) indicates a 2.45 times greater chance of having MDD. Age (< 0.001), diarrhea (0.01), prenatal care (0.06), mother's education (< 0.001), computer access (< 0.001), wealth quantile (< 0.001), and residence (< 0.001) were significantly associated with meeting MDD. However, gender (0.6) and mother's age (0.4) both were statistically insignificant in meeting MDD. Regarding mothers' education, compared to no education, the chance of MDD is 1.45 times greater for highly educated mothers in the Punjab province. Dietary diversity among children aged 6 to 23 months in Pakistan is low. It is recommended that mothers should be aware and encouraged to use dietary diverse food for infants and younger children.

Assessment of Efficiency of Bioactive Glass, Self-Assembling Peptide, and Ozone Remineralising Agents on Artificial Carious Lesion

ABSTRACT Objective: To assess the efficacy of bioactive glass, self-assembling peptide, and ozone-remineralizing agents on the artificial carious lesion. Material and Methods: On the extracted 60 premolar teeth, an artificial carious lesion/demineralization was created. Later, the remineralization of demineralized teeth was done with respective remineralizing agents (Group A: Calcium sodium phosphosilicate (bioactive glass), Group B: Self-assembling peptide, Group C: Ozone remineralizing agents and Group D (Control): De ionized water. The degree of demineralization and remineralization were evaluated using the Vickers Hardness Number. Results: There was a decrease in microhardness from baseline to demineralization in all the groups, and this reduction was found to be statistically considerable. After the remineralization of demineralized samples with respective remineralizing agents, there was an increase in microhardness of 312.38, 276.67, and 254.42 in groups A, B, and C, respectively. In contrast, in Group D, there were no changes. Conclusion: Bioactive glass and self-assembling peptides had higher remineralizing capacities, which can be used to treat early carious lesions.

Factors associated with maternal health services utilization in Pakistan: Evidence from Pakistan maternal mortality survey, 2019.

BACKGROUND: This study investigates the factors associated with maternal health services utilization in Pakistan using two outcome indicators, ideal antenatal care (IANC), defined as the pregnant woman receiving all the essential services included in standard antenatal care, and skilled birth attendance (SBA). METHODS: This study used the Pakistan Maternal Mortality Survey 2019 data. The study utilized binary logistic regression models to investigate the adjusted association between the outcome variables, separately for IANC and SBA, and the independent variables, education, wealth, parity, and residence. RESULTS: Wealth showed a positive association with utilization of IANC (adjusted odds ratio [AOR] = 11.48, 95% CI = 7.76, 16.99) and SBA (AOR = 4.37, 95% CI = 3.30,5. 80). Maternal age was associated only with IANC for women aged 35 or more years (AOR = 1.31, 95% CI = 1.06, 1.62). Increased likelihood of utilization of IANC and SBA services was also observed for women with formal education. Women who had 3-5 previous live births had higher odds of using IANC and SBA than women who had 1-2 or more than five previous live births. Urban residency was not correlated with either IANC or SBA. CONCLUSION: When compared to the wealthy and educated quintile, women in the lower wealth quintile and those without any formal education were less likely to utilize ANC and SBA services. A comprehensive and multipronged approach from the health and education sectors is needed to improve maternal health in Pakistan.

Barriers experienced by community midwives to provide basic emergency obstetric and newborn care in rural Pakistan.

BACKGROUND: Considering the high maternal mortality rate, the government of Pakistan has deployed Community Midwives (CMWs) in rural areas of Pakistan. This relatively new cadre of community-based skilled birth attendants has previously reported to experience several challenges in providing maternal and child healthcare. However, what barriers they experience in providing basic emergency obstetric and newborn care needs to be further studied. METHODS: This was a cross-sectional study conducted in twelve districts in Sindh province, Pakistan, with poor maternal and child health indicators. A total of 258 CMWs participated in this study and completed the questionnaire on a pretested, validated tool in their community-based stations. The trained data collectors completed the questionnaires from the respondents. The problems identified were categorized into three major issues: financial, and transport and security related; and were analyzed accordingly. Ethical approval was obtained from the institutional review board (IRB) of Health Services Academy (HSA) Islamabad, Pakistan. RESULTS: The majority (90%) of 258 CMWs had formal training in maternal and neonatal care from the recognized institutions. Financial difficulties faced by CMWs were identified as the most frequent barriers and others were transport, security, and other issues. In univariate analysis, 38.1% and 61.9% of the community midwives who faced financial difficulties had completed a graduation or intermediate level of education, respectively (p = 0.006). Round-the-clock availability for emergencies was inversely associated with having financial difficulties, i.e., 71.4%, in contrast to 28.4% who had financial difficulties were available round-the-clock for emergency calls in their community clinics (p = 0.008). Formal training (p = 0.001), work experience (p = 0.015), longer duration of work (p = 0.003), and liaison with health workers and posting district (p = 0.001) had statistically significantly higher transport related issues. Security difficulties faced by CMWs and a set of correlates such as formal training (p = 0.019), working experience (p = 0.001), longer duration of work (p = 0.023), 24 h of availability on call (p = 0.004), liaison with traditional birth attendants (TBAs) in the community (p = 0.002), and district of posting (p = 0.001) were statistically significantly different. Other issues like working experience (p = < 0.001) and Liaison with TBAs in the community (p = < 0.001) were found statistically significant. CONCLUSION: Financial, transportation and security related barriers were commonly reported by community midwives in the delivery of basic emergency obstetric and newborn care in rural Pakistan.

Respectful Maternal Care Experience in Low- and Middle-Income Countries: A Systematic Review.

Background and Objectives: Respectful maternity care promotes practices that acknowledge women's preferences and women and newborns' needs. It is an individual-centered strategy founded on ethical and human rights principles. The objective of this systematic review is to identify the impact of income on maternal care and respectful maternity care in low- and middle-income countries. Materials and Methods: Data were searched from Google Scholar, PubMed, Web of Science, NCBI, CINAHL, National Library of Medicine, ResearchGate, MEDLINE, EMBASE database, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Maternity and Infant Care database. This review followed PRISMA guidelines. The initial search for publications comparing low- and middle-income countries with respectful maternity care yielded 6000 papers, from which 700 were selected. The review articles were further analyzed to ensure they were pertinent to the comparative impact of income on maternal care. A total of 24 articles were included, with preference given to those published from 2010 to 2023 during the last fourteen years. Results: Considering this study's findings, respectful maternity care is a crucial component of high-quality care and human rights. It can be estimated that there is a direct association between income and maternity care in LMICs, and maternity care is substandard compared to high-income countries. Moreover, it is determined that the evidence for medical tools that can enhance respectful maternity care is sparse. Conclusions: This review highlights the significance of improving maternal care experiences, emphasizing the importance of promoting respectful practices and addressing disparities in low- and middle-income countries.

Recent advances in chitosan-based materials; The synthesis, modifications and biomedical applications.

The attention to polymer-based biomaterials, for instance, chitosan and its derivatives, as well as the techniques for using them in numerous scientific domains, is continuously rising. Chitosan is a decomposable naturally occurring polymeric material that is mostly obtained from seafood waste. Because of its special ecofriendly, biocompatible, non- toxic nature as well as antimicrobial properties, chitosan-based materials have received a lot of interest in the field of biomedical applications. The reactivity of chitosan is mainly because of the amino and hydroxyl groups in its composition, which makes it further fascinating for various uses, including biosensing, textile finishing, antimicrobial wound dressing, tissue engineering, bioimaging, gene, DNA and drug delivery and as a coating material for medical implants. This study is an overview of the different types of chitosan-based materials which now a days have been fabricated by applying different techniques and modifications that include etherification, esterification, crosslinking, graft copolymerization and o-acetylation etc. for hydroxyl groups' processes and acetylation, quaternization, Schiff's base reaction, and grafting for amino groups' reactions. Furthermore, this overview summarizes the literature from recent years related to the important applications of chitosan-based materials (i.e., thin films, nanocomposites or nanoparticles, sponges and hydrogels) in different biomedical applications.

Crafting a Blueprint for MicroRNA in Cardiovascular Diseases (CVDs).

Cardiovascular diseases (CVDs) encompass a range of disorders, from congenital heart malformation, cardiac valve, peripheral artery, coronary artery, cardiac muscle diseases, and arrhythmias, ultimately leading to heart failure. Despite therapeutic advancements, CVDs remain the primary cause of global mortality, highlighting the need for a thorough knowledge of CVDs at the level of molecular structure. Gene and microRNA (miRNA) expression variations significantly influence cellular pathways, impacting an organism's physiology. MiRNAs, in particular, serve as regulators of gene expression, playing critical roles in essential cellular pathways and influencing the development of various diseases, including CVD. A wealth of evidence supports the involvement of miRNAs in CVD progression. These findings highlight the potential of miRNAs as valuable diagnostic biomarkers and open new avenues for their therapeutic application in CVDs. This study focuses on the latest advancements in identifying and characterizing microRNAs, exploring their manipulation and clinical application, and discussing future perspectives.

A Randomized Controlled Trial of Blood Pressure Reduction Based on Disease Control Priorities 3 in Pakistan to Manage and Control Hypertension.

INTRODUCTION: According to American Heart Association standards, hypertension is classified into three stages based on blood pressure measurements: essential hypertension, stage 1 hypertension, and stage 2 hypertension. The global target is to reduce the prevalence of high blood pressure by 25% by the year 2025. Worldwide, the prevalence of high blood pressure among men and women aged 18 and above reported to be 24% and 20%, respectively. AIM: The aim of this study was to overall reduce high blood pressure of hypertensive patients to the recommended level of 140/90 mm of Hg through implementing a non-pharmacological and multi-component intervention based on Disease Control Priorities (3rd edition). METHODS: A randomized controlled trial in which a multi-component intervention for lowering high blood pressure was tested. This was pilot-tested for its acceptance, appropriateness, and relevance, explored through an earlier formative research and desk review conducted from the available evidence. A total of 240 study participants were enrolled after obtaining informed consent. Ethical approval was obtained from the Institutional Review Board of Health Services Academy and the trial was registered in clinicaltrials.gov number NCT04336631. SPSS software version 21 was used to enter and analyze the data. RESULTS: High blood pressure of hypertensive patients in a hospital setting during 03 months yielded -23.9 mm Hg of systolic blood pressure reduction (95% confidence interval, p ≤ 0.005). A significant reduction was observed in intervention group after delivering the intervention. Compared to patients in the usual care group, improved health outcomes were achieved for diet control, reducing salt intake and increased physical exercise. In the intervention group, the mean blood pressure among male hypertensive patients was 145/90 mm Hg and in female hypertensive patients, the mean blood pressure was recorded as 140/100 mm Hg. CONCLUSION: High blood pressure was significantly reduced in hypertensive patients who adhered to a low salt diet, weight loss measures, and increased physical activity.

Development of a tool for objectively measuring somatic pain in the low back region based on a longitudinal diagnostic study conducted in Karachi, Pakistan.

OBJECTIVES: This study aimed at devising an objective method for quantifying pain in the low back region using pressure pain threshold (PPT) and demographic factors as predictive variables. METHODS: The research was conducted in two phases. Phase I was a longitudinal exploratory study conducted on 49 men aged 18-50 years with chronic low back pain (CLBP) recruited using non-probability purposive sampling. We used Visual Analogue Scale to record pain intensity and pain affect, and Disability Rating Index to record associated disability. PPT was measured on 12 different locations on the lower back using a manual algometer. These measurements were taken from each participant in 1 to 6-follow-up visits, depending on improvement in the individual's symptoms. In phase II additional 33 subjects, both men and women with varying durations of low back pain were recruited using non-probability convenience sampling. Repeated measures ordinal regression and receiver's operating characteristic curve analyses were performed to develop predictive models using STATA V.16.0 and R V.3.5.2 software. These models were given an interface using Microsoft Excel. A p value of <0.05 was considered statistically significant. RESULTS: Higher PPT scores, increased lean body mass, lean physique and a longer duration of CLBP were associated with a reduction in CLBP intensity, affect and disability. Advancing age was associated with an increase in these outcomes. Collectively, these factors were found to predict pain intensity, affect, and disability with 63%-65% diagnostic accuracy in phase I, however, this diagnostic accuracy increased to 65%-78% in phase II. CONCLUSION: We developed a new outcome tool 'Pain Calculator' that can objectively measure low back pain with sufficient statistical accuracy. With further refinement, this tool in the future can be configured to measure somatic pain in different regions as well, affording clinicians and researchers much-needed objectivity while recording pain levels. TRIAL REGISTRATION NUMBER: NCT04482075.

Enhanced Solubility and Biological Activity of Dexibuprofen-Loaded Silica-Based Ternary Solid Dispersions.

The current study was designed to formulate ternary solid dispersions (TSDs) of dexibuprofen (Dex) by solvent evaporation to augment the solubility and dissolution profile, in turn providing gastric protection and effective anti-inflammatory activity. Initially, nine formulations (S1 to S9) of binary solid dispersions (BSDs) were developed. Formulation S1 comprising a 1:1 weight ratio of Dex and Syloid 244FP® was chosen as the optimum BSD formulation due to its better solubility profile. Afterward, 20 TSD formulations were developed using the optimum BSD. The formulation containing Syloid 244FP® with 40% Gelucire 48/16® (S18) and Poloxamer 188® (S23) successfully enhanced the solubility by 28.23 and 38.02 times, respectively, in pH 6.8, while dissolution was increased by 1.99- and 2.01-fold during the first 5 min as compared to pure drug. The in vivo gastroprotective study in rats suggested that the average gastric lesion index was in the order of pure Dex (8.33 ± 2.02) > S1 (7 ± 1.32) > S18 (2.17 ± 1.61) > S23 (1.83 ± 1.04) > control (0). The in vivo anti-inflammatory study in rats revealed that the percentage inhibition of swelling was in the order of S23 (71.47 ± 2.16) > S18 (64.8 ± 3.79) > S1 (54.14 ± 6.78) > pure drug (18.43 ± 2.21) > control (1.18 ± 0.64) after 6 h. ELISA results further confirmed the anti-inflammatory potential of the developed formulation, where low levels of IL-6 and TNF alpha were reported for animals treated with S23. Therefore, S23 could be considered an effective formulation that not only enhanced the solubility and bioavailability but also reduced the gastric irritation of Dex.

Correlates of early initiation of breast feeding and prelacteal feeding: a cross-sectional study in Sindh province of Pakistan.

OBJECTIVES: The objective of this study was to determine the prevalence and correlates of early initiation of breast feeding and prelacteal feeding in highly disadvantaged districts in Pakistan. DESIGN: This cross-sectional study design. SETTINGS: This study was carried out in twelve districts of the Sindh province of Pakistan. PARTICIPANTS: A total of 4800 mothers with children under 2 years, selected through a multistage random sampling method. DATA ANALYSIS: Bivariate association, survival analysis (Kaplan-Meier and Cox proportional hazard techniques), multivariate linear regression and the ordinary least square model were used. RESULTS: The results show that the prevalence of early initiation of breast feeding was 68% and prelacteal feeding was 32%. Adequate treatment, proper guidance at antenatal care visits, postpartum health check, normal birth with skilled birth attendants, institutional birth, skin-to-skin contact at birth and birth size were all associated with early breastfeeding initiation (p<0.001). The odds of early initiation of breast feeding after birth are higher if the respondents received proper guidance (OR 2.05; 95% CI 1.02 to 4.11) or made skin-to-skin contact (OR 10.65; 95% CI 6.82 to 16.65). Bivariate association between the prelacteal feeding and a set of correlates suggests that all variables under study were significantly associated with the outcome variable of interest at a 95% or higher significance level. The factors which significantly reduced the odds of prelacteal feeding were adequate treatment (OR 0.29; 95% CI 0.23 to 0.37) and postpartum health check (OR 0.65; 95% CI 0.53 to 0.80). CONCLUSION: Sudy concludes that the correlates like adequate treatment of mothers during labour, postpartum health check-up, normal birth with skilled birth attendants, institutional births and skin-to-skin contact between mother and the baby determine the early initiation of breast feeding and prelecteal feeding. Early initiation of breast feeding needs to be encouraged, and communities must be educated against the use of prelacteal feeding.

Comparative transcriptome and co-expression network analysis revealed the genes associated with senescence and polygalacturonase activity involved in pod shattering of rapeseed.

BACKGROUND: The pod shattering (PS) trait negatively affects the crop yield in rapeseed especially under dry conditions. To better understand the trait and cultivate higher resistance varieties, it's necessary to identify key genes and unravel the PS mechanism thoroughly. RESULTS: In this study, we conducted a comparative transcriptome analysis between two materials significantly different in silique shatter resistance lignin deposition and polygalacturonase (PG) activity. Here, we identified 10,973 differentially expressed genes at six pod developmental stages. We found that the late pod development stages might be crucial in preparing the pods for upcoming shattering events. GO enrichment results from K-means clustering and weighed gene correlation network analysis (WGCNA) both revealed senescence-associated genes play an important role in PS. Two hub genes Bna.A05ABI5 and Bna.C03ERF/AP2-3 were selected from the MEyellow module, which possibly regulate the PS through senescence-related mechanisms. Further investigation found that senescence-associated transcription factor Bna.A05ABI5 upregulated the expression of SAG2 and ERF/AP2 to control the shattering process. In addition, the upregulation of Bna.C03ERF/AP2-3 is possibly involved in the transcription of downstream SHP1/2 and LEA proteins to trigger the shattering mechanism. We also analyzed the PS marker genes and found Bna.C07SHP1/2 and Bna.PG1/2 were significantly upregulated in susceptible accession. Furthermore, the role of auxin transport by Bna.WAG2 was also observed, which could reduce the PG activity to enhance the PS resistance through the cell wall loosening process. CONCLUSION: Based on comparative transcriptome evaluation, this study delivers insights into the regulatory mechanism primarily underlying the variation of PS in rapeseed. Taken together, these results provide a better understanding to increase the yield of rapeseed by reducing the PS through better engineered crops.

Postnatal women's perception on person-centered maternity care in twin cities of Rawalpindi and Islamabad: a descriptive study.

BACKGROUND: Person-Centered Maternity Care (PCMC) is known as one of the most important components of maternal care. Every woman has the ultimate right of respectful health care. Previous research documents that lack of supportive care and respectful behavior experienced by pregnant women can act as a barrier to the utilization of health care services. Few studies have used PCMC tool to document this phenomenon. The objective of this descriptive study was to assess the women's perception of PCMC in Pakistan. METHODS: Three hundred and seventy-seven (377) postnatal women of ages 18-49 years participated in the research. The study sites were secondary and tertiary care hospitals located in the twin cities of Rawalpindi and Islamabad. The PCMC tool used in this study is a validated scale with three sub-domains of i) communication and autonomy, ii) supportive care, and iii) dignity and respect. Data was analyzed using SPSS version 16, and descriptive and bivariate analysis was undertaken. RESULTS: The PCMC mean score was 54 ± [10.7] out of 90. About half (55%) of women had good perception of PCMC. Sub-domain of supportive care scored the lowest as compared to the other two domains. Overall, 36% women reported physical abuse while 22% reported verbal abuse at the hands of the healthcare providers. Most of the women (88%) said that health providers did not introduce themselves. About 30% women claimed that health care providers never asked for permission before doing any medical procedures and 20% of women claimed that doctors did not describe the purpose of examination while 178 (47%) of women said that health provider explained the purpose of medications all the time, additionally, about 14% were never given the choice to ask questions. CONCLUSION: The study concluded that the majority of postnatal women perceived that they were not getting optimum Person-Centered Maternity Care. Some core aspects in supportive care domain were missing. In order to improve the quality of hospital-based childbirths, efforts are needed to improve the quality of care.

Perceptions of health care workers on maternal and child health services in Pakistan during COVID-19: A cross-sectional study.

Background: Maternal and child healthcare service delivery in vulnerable and fragile health systems has suffered a tremendous impact owing to the shift in focus to curtail the COVID-19 pandemic. We aimed to evaluate the impact of the COVID-19 pandemic on maternal and child healthcare services to inform policy advice for a more resilient maternal and child healthcare service delivery in Pakistan. Methods: A descriptive cross-sectional study was conducted. A structured and validated questionnaire was transformed into an online version and a link was first sent to about 300 healthcare professionals to achieve a sample size of 203, including medical doctors, nurses, and other paramedical staff working in public sector health facilities of the four provinces of Pakistan. The questionnaire was responded to by 195 participants. The Chi-Square test was used to determine the statistical differences between the categorical variables. Results: Although about two-thirds of the participants reported a moderate adherence to protocols and procedures to prevent COVID-19 in their health facilities, the maternal and child health service delivery-related indicators declined during the pandemic. For instance, 66.8% and 62.4% of the participants, respectively, did not agree that a Neonatal Intensive Care Unit and an Intensive Care Unit to admit sick newborns and women with obstetric complications during the COVID-19 pandemic were available during the COVID-19 pandemic. In addition, 23% and 20% of the participants, respectively, reported that staff availability and the provision of cesarean section were moderate to extremely affected. The association between job designation and the impact of COVID-19 was statistically significant (χ2 p = 0.038). Conclusions: The study suggests that maternal and child healthcare services including C-Section, perinatal care, and inpatient care of newborns in Pakistan may have been moderately affected by the COVID-19 pandemic.

Experience of psychologists in the delivery of cognitive behaviour therapy in a non-western culture for treatment of substance abuse: a qualitative study.

BACKGROUND: Psychotherapy is the preferred form of treatment for psychological disorders worldwide. Cognitive behaviour therapy (CBT) is one of the most widely used psychotherapies due to its proven efficacy for psychological disorders, including substance abuse. However, CBT was developed in the West according to the culture of developed countries. Therefore, it requires cross-cultural adaptation for non-Western countries. Pakistan is one of the developing non-Western countries where substance use disorders are increasing at an alarming rate. Despite the proven efficacy of CBT for substance use disorders, there is a dearth of its utilization in Pakistan. Therefore, in the present study, in-depth qualitative interviews were conducted with CBT practitioners in Pakistan to understand barriers and challenges in this regard. The study was a part of a broader project aimed at cultural adaptation of CBT for people with substance use disorders (SUDs) in Pakistan. METHODS: In-depth qualitative interviews were conducted with CBT practitioners (N = 8) working in rehabilitation centres and hospitals in Islamabad, Pakistan. Thematic content analysis was conducted to develop core themes from the data. RESULTS: CBT for SUDs requires some adjustments according to Pakistani culture for successful utilization. The challenges in providing CBT for SUDs revolved around three main themes, i.e., the mental health system, societal practices, and therapeutic issues, and 10 subthemes. CONCLUSION: In order to utilize the benefits of CBT for SUDs in Pakistan, cultural adaptation is necessary as an initial step. However, its delivery requires stringent modifications in the health care system to address these challenges.

A Qualitative Study of Stakeholders' Views on Pharmacovigilance System, Policy, and Coordination in Pakistan.

Objectives: Due to the absence of necessary rules, poor coordination, and various challenges, the pharmacovigilance system of Pakistan is not optimally functional at all levels of the health system. The objective of the study was to assess the stakeholders' perceptions of the current ADR reporting system and to identify the pharmacovigilance policy issues and problems of effective coordination. Methodology: Stakeholders from a broad range of disciplines, academia, regulatory authorities, the pharmaceutical industry, international health organizations, as well as pharmacovigilance experts, and healthcare professionals were included in the study. A total of 25 stakeholders throughout Pakistan were interviewed during exploratory semi-structured interviews. The interviews were recorded digitally, transcribed, coded, compared, and grouped according to their similarity of themes. Participants provided insights into gaps, limitations, and challenges of Pakistan's current ADR reporting system, issues with proposed pharmacovigilance rules, and coordination difficulties. Results: The majority of the participants considered the ADR reporting system in Pakistan to be improving but in a nascent phase. The identified gaps, challenges, limitations of the system, and barriers to reporting were labeled as reasons for limited functioning. Almost all stakeholders were aware of the existence of draft pharmacovigilance rules; however, participants in the industry were familiar with the contents and context of draft pharmacovigilance rules. Bureaucratic red tape and lack of political will appeared to be the top reasons for delaying the approval of the pharmacovigilance rules. Wider consultation, advocacy, and awareness sessions of policymakers and HCPs were suggested for early approval of rules. Participants unanimously agreed that the approval of rules shall improve the quality of life and reduce the economic burden along with morbidity and mortality rates. The need for greater and collaborative coordination among the stakeholders in promoting medicines' safety was highlighted. All participants suggested the use of media and celebrities to disseminate the safety information. Conclusion: Participants showed partial satisfaction with the way pharmacovigilance in Pakistan is moving forward. However, stakeholders believed that engagement of multi-stakeholders, approval of pharmacovigilance rules, and the establishment of pharmacovigilance centers in provinces, hospitals, and public health programs (PHPs) shall support in achieving the desired results.

Strengthening Breast Cancer Screening Mammography Services in Pakistan Using Islamabad Capital Territory as a Pilot Public Health Intervention.

Late diagnosis of treatable breast cancer is the reason for higher breast cancer mortality. Until now, no public breast cancer facility has been established in the Islamabad Capital Territory. First, a Federal Breast Screening Center (FBSC) was established. Afterward, awareness campaigns about breast cancer were organized among the public. Subsequently, women above 40 years of age were provided with mammography screenings. Data were analyzed in SPSS version 22.0. An intervention was performed using a six tier approach to strengthening the health system. Utilizing the offices of the FBSC and the national breast cancer screening campaign, breast cancer awareness has become a national cause and is being advocated by the highest offices of the country. The number of females undergoing mammography has increased each year, starting from 39 in 2015 to 1403 in 2019. Most of the cases were BI-RAD I (n = 2201, 50.74%) followed by BI-RAD II (n = 864, 19.92%), BI-RAD III (n = 516, 11.89%), BI-RAD IV (n = 384, 8.85%), BI-RAD V (n = 161, 3.71%), and BI-RVAD VI (n = 60, 1.38%). The current study has theoretical and practical implications for the contemplation of policymakers. The FBSC can serve as a model center for the establishment of centers in other parts of the country, thereby promoting nationwide screening coverage.

Cross-Sectional Analysis of Impulse Indicator Saturation Method for Outlier Detection Estimated via Regularization Techniques with Application of COVID-19 Data.

Impulse indicator saturation is a popular method for outlier detection in time series modeling, which outperforms the least trimmed squares (LTS), M-estimator, and MM-estimator. However, using the IIS method for outlier detection in cross-sectional analysis has remained unexplored. In this paper, we probe the feasibility of the IIS method for cross-sectional data. Meanwhile, we are interested in forecasting performance and covariate selection in the presence of outliers. IIS method uses Autometrics techniques to estimate the covariates and outlier as the number of covariates P > n observations. Besides Autometrics, regularization techniques are a well-known method for covariate selection and forecasting in high-dimensional analysis. However, the efficiency of regularization techniques for the IIS method has remained unexplored. For this purpose, we explore the efficiency of regularization techniques for out-of-sample forecast in the presence of outliers with 6 and 4 standard deviations (SD) and orthogonal covariates. The simulation results indicate that SCAD and MCP outperform in forecasting and covariate selection with 4 SD (20% and 5% outliers) compared to Autometrics. However, LASSO and AdaLASSO select more covariates than SCAD and MCP and possess higher RMSE. Overall, regularization techniques possess the least RMSE than Autometrics, as Autometrics possesses the least average gauge at the cost of the least average potency. We use COVID-19 cross-sectional data collected from 1 July 2021 to 30 September 2021 for real data analysis. The SCAD and MCP select CRP level, gender, and other comorbidities as an important predictor of hospital stay with the least out-of-sample RMSE of 7.45 and 7.50, respectively.

Endodontic Management of Mandibular Second Premolar with Vertucci Root Canal Configuration Type V.

The diversity of root canal anatomy in permanent dentition is quite common. Understanding the basic anatomy of the root canal morphology and its variations is particularly important for successful root canal treatment. Mandibular second premolar usually consists of a single root with a single root canal. The presence of split roots in the apical third of the root with two separate root canals is quite rare. The major cause of endodontic failure in missed canals is that it harbors bacteria and other microorganisms. Careful radiographic interpretation and clinical examination of the pulp chamber will be helpful in locating canal orifices. The mandibular premolars with Vertucci type V canal configuration pose a challenge in clinical management. Identifying them early is important to aid appropriate modification in treatment protocol. In this case report, important modifications of clinical steps and application of magnification for successful management with access chamber modification are explained.
