Knowledge, attitudes, and practices of vaccinators about expanded programs on immunization: a cross-sectional study.

Introduction: The periodic evaluation of knowledge, attitudes, and practices (KAP) of healthcare workers, including vaccinators, concerning expanded programs on immunization (EPI) is very crucial for a better healthcare system. This study was carried out to assess the KAP of vaccinators about the EPI, including cold storage of vaccines and their practices related to vaccine cold chain management. Method: A cross-sectional study was conducted from January 2022 to June 2022 among registered vaccinators in the twin cities (Islamabad and Rawalpindi) of Pakistan. A structured self-administered questionnaire (English and Urdu) was developed as per the Pakistan national EPI policy and strategic guidelines 2022 and World Health Organization (WHO) guidelines, as well as from earlier studies (Cronbach's alpha value of 0.734). The final questionnaire consisted of closed-ended questions in four sections, including sociodemographic information, knowledge (with dichotomous variables of yes/no), attitudes (with a 5-point Likert scale ranging from strongly agree to strongly disagree), and handling of vaccines and cold chain management. Completed questionnaires were entered into Microsoft Excel and then imported into SPSS version 25 for statistical analysis. Results: A total of 186 vaccinators completely filled out their questionnaires, with a 97.9% response rate. More than half of the participants (57.5%) had no training related to EPI. Most of the respondents had a moderate to poor level of knowledge regarding EPI. The overall attitude was positive, and 57% of the participants strongly agreed that the national immunization programs can significantly contribute to the decrease in morbidity and mortality rates among children. In the current study, participants showed good practices toward EPI, vaccine storage, and cold chain management. The majority (93.5%) of the participants checked the expiry of vaccines at regular intervals to maintain the first expiry first out (FEFO) in their healthcare setting. Discussion: In conclusion, most of the vaccinators had moderate to poor knowledge, a positive attitude, and good practices toward EPI, vaccine cold storage, and cold chain management. Lack of training among vaccinators on EPI was also observed. These findings have suggested that continuous training, education, and regular supervision of vaccinators in EPI are important for maximum immunization effectiveness and coverage.

COVID-19 stress and wellbeing: A phenomenological qualitative study of Pakistani Medical Doctors.

The COVID-19 stress and increased job pressure have largely affected healthcare professionals' various life domains. This study particularly explores the effect of stress caused by treating COVID-19 patients on medical doctors' wellbeing. To explore this phenomenon, we interviewed 12 doctors treating COVID-19 patients in hospitals of metropolitan cities in Pakistan. The thematic analysis using NVivo V.12 Plus software of interviews resulted in four major themes, COVID-19 Stressors, Effects of Stress, Nature and Personality, Stress Relievers, and Stress Coping Strategies. Physicians were physically and emotionally stressed as a result of the intense work. Although they were carrying a lot of pain and hurt on their insides, participants demonstrated a sense of professional determination to overcome obstacles. Physicians are currently dealing with their emotional issues, and they should have access to complete professional help to ensure their wellbeing. The COVID-19 pandemic's mental health effects are anticipated to last far longer than the physical health effects. This study is well-positioned to investigate frontline physicians' opinions and attitudes concerning the COVID-19 and its impact on their daily lives and mental health. This research will help implement context-specific innovative mental health solutions to help the frontline workers.

Online Customer Experience Leads to Loyalty via Customer Engagement: Moderating Role of Value Co-creation.

With the increasing growth of online shopping, businesses are intertwining to establish new shopping antecedents. Customer experience has steadily become the most important source of retailers' long-term competitive advantage via difference. To preserve long-term and sustained consumer loyalty, retailers must continually improve the customer experiences. This study presents a framework for online retailing in a digital environment called the Online Customer Experience-Engagement Context model in the presence of value co-creation (VCC). Data was gathered from 189 people who purchased products online. For additional analysis, testing the hypothesis, and model construction, SPSS 26 and Smart-PLS were used. The data was then evaluated further using descriptive statistics, path analysis, measurement, and structural model. The findings show that the online customer experience (measured as shopping environment, shopping procedure, staff service experience, and product experience) substantially influenced customer engagement, which improved customer loyalty. The VCC strengthened the link between online customer experience and customer engagement. It suggests that including consumers in co-creating a delightful online customer experience from time to time may be a valuable strategy for online retailers to increase customer engagement and loyalty. To create an overarching outcome, information integration theory (IIT), multi-attribute utility theory (MAUT), and the attitude-behavior-context theory (ABC) theories are converged to explain the proposed model in the study.

Adjunctive vitamin D therapy in various diseases in children: a scenario according to standard guideline.

BACKGROUND: Adherence to standard guidelines is imperative when question comes to disease management. The present study aimed to evaluate the administration of adjunctive vitamin D therapy in various diseases, its adherence to standard guideline and the effect of socioeconomic status on the consumption of vitamin D in children. METHODS: Cross sectional observational study was conducted among 400 ambulatory pediatric patients at Children's Hospital, Pakistan Institute of Medical Sciences Islamabad, from November 2017 to June 2018. Data were collected by a self-designed structured questionnaire from the patient's medical chart. Adjunctive vitamin D therapy adherence was evaluated by the U. S endocrinology clinical practice guideline of vitamin D deficiency. The association between socioeconomic status and consumption of vitamin D was examined by chi-square. Alpha value (p ≤ 0.005) was considered statistically significant. Statistical analysis was done by SPSS version 25. RESULTS: In 400 patients, 9 diseases and 21 comorbid conditions were identified, in which adjunctive vitamin D therapy was prescribed. Adherence to vitamin D testing in high-risk vitamin D deficiency diseases as; seizures (3.8%), bone deformities (13.3%), steroid-resistant nephrotic syndrome (0.0%), cerebral palsy (5.9%) and meningitis (14.3%). Adherence to prescribed vitamin D dose was in (41.3%) patients in various diseases. Significant association (p < 0.05) was found between socioeconomic status and consumption of vitamin D in children and mothers. CONCLUSIONS: It was found that adjunctive vitamin D was being prescribed in various diseases and comorbidities. Overall poor adherence to the standard guideline was observed in disease management in children. Low socioeconomic status affects vitamin D supplementation consumption in children.

Access to Insulin Products in Pakistan: A National Scale Cross-Sectional Survey on Prices, Availability, and Affordability.

Background: Diabetes is among the top ten most prevalent diseases in Pakistan, and the availability of medicines to treat the disease is vital for a great percentage of the country's population. Insulin was discovered a century ago; however, its access in several parts of the globe remains an issue. This study aims to evaluate prices, availability, and affordability (access components) of insulin and five comparator medicine access in Pakistan. Methods: A nationwide cross-sectional survey was conducted to evaluate the access to insulin and some comparator medicines in eight cities of Pakistan, using a modified WHO/HAI methodology. The survey included 80 medicine outlets, i.e., 40 private pharmacies and 40 public hospitals. Data for every unique insulin product available in the Pakistani market were obtained, including five comparator medicines. Percentage availability, median unit prices (MUPs), and affordability (the number of days' wages (NDWs) required for a month's course by the lowest-paid unskilled government worker) of all products were calculated, including originator brands (OBs) and biosimilar (BS) products. Results: Of all insulin products surveyed (n = 320), 87.5% were manufactured by foreign multinational companies (MNCs). None of the insulin products had an ideal availability of 80% in any of the surveyed health facilities. In the public sector, none of the insulin products had an availability of more than 50%. In the public sector, the overall availability of human insulin was 70% (including OB and BS). While in the private sector, the overall availability of human insulin was 90% and that of analog insulin was 62.5%. The analog insulin products were 72.8% costlier than the human insulin products. The median prices of BS insulin were 25.4% lower than the OB products, indicating that almost one-fourth of the cost could be saved by switching to BS human insulin from OB human insulin. All oral anti-diabetic medicines were found to be affordable, whereas none of the insulin was affordable. The NDWs for human and analog insulin were 1.38 and 5.06. Conclusion: In Pakistan, the insulin availability falls short of the WHO's benchmark of 80%. Insulin continues to be unaffordable in both private and government sectors. To increase insulin access, the government should optimize insulin procurement at all levels, promote local production, enforce biosimilar prescribing, and provide financial subsidies for these products.

Brand Love: Role of Online Customer Experience, Value Co-creation, and Relationship Quality.

Customer experience is a source of retailers' long-term competitive advantage. This study has examined the relationship between online customer experience and brand love through the mechanism of relationship quality in the context of online shopping in Pakistan. The moderating effect of value co-creation on the relationship of online customer experience with relationship quality and brand love has also been examined. Data were collected from a purposive sampling of 189 online customers in an online survey. Results showed that online customer experience significantly impacts customer relationship quality, which leads to brand love. The relationship between online customer experience and relationship quality is found more robust at high levels of value co-creation. However, we observed a significant negative moderating effect of value co-creation on the direct relationship between online customer experience and brand love. It suggests that including customers in the value co-creation process and affording them a pleasurable online shopping experience may be an excellent way to enhance customer relationship quality and brand love. Theoretical and practical implications of these findings are discussed.

New drugs and new concerns: Gaining insight through Pharmacovigilance of direct acting Anti-Viral's in chronic HCV patients.

OBJECTIVE: The study aimed to assess the safety profile of Direct Acting Anti-Viral's (DAAs) among patients with chronic Hepatitis C Virus (HCV). METHODS: This multicenter, analytical cross-sectional study was conducted in six gastroenterology and Hepatology centers including Liver Center Faisalabad, Allama Iqbal Medical Institute and Liver Center DHQ Hospital Sialkot, Isra Hospital Hyderabad, Allied Hospital Faisalabad and Rehman Medical Institute Peshawar, between May 2018 and May 2019. The data regarding patient demographics, treatment plan and the frequency of Adverse Events (AEs), and their severity was collected using a pre-designed questionnaire and analyzed through SPSS version 20.0. RESULTS: A total of 511 HCV patients were enrolled, with an overall male majority. Around 66.3% patients experienced a total of 419 AEs, out of which 61 events were suspected from DAAs while remaining 317 events were associated with Ribavirin. Pyrexia (24.6%) and fatigue (14.8%) were the most commonly reported AEs among patients receiving DAAs. Factors such as Ribavirin-based treatments and the presence of Cirrhosis were more likely to promote AEs occurrence OR [95%CI] i.e. 5.2(2.3-9.1) and 1.9(1.1-3.1) respectively (p < 0.05). CONCLUSION: It is concluded from the study results that DAAs have displayed promising outcomes due to the minimal and minor AEs reported.

Knowledge, attitude and perceptions about Crimean Congo Haemorrhagic Fever (CCHF) among occupationally high-risk healthcare professionals of Pakistan.

BACKGROUND: Crimean Congo Haemorrhagic Fever (CCHF), a tropically neglected infectious disease caused by Nairovirus, is endemic in low middle-income countries like Pakistan. Emergency health care professionals (HCPs) are at risk of contracting nosocomial transmission of CCHF. We, therefore, aim to analyze the knowledge, attitudes, and perceptions (KAP) of at-risk physicians, nurses, and pharmacists in Pakistan and the factors associated with good KAP. METHOD: A validated questionnaire (Cronbach's alpha 0.71) was used to collect data from HCPs in two CCHF endemic metropolitan cities of Pakistan by employing a cross-sectional study design. For data analysis percentages, chi-square test and Spearman correlation were applied by using SPSS version 22. RESULTS: Of the 478 participants, 56% (n = 268) were physicians, 37.4% (n = 179) were nurses, and 6.5% (n = 31) were pharmacists. The proportion of HCPs with good knowledge, attitude, and perception scores was 54.3%, 81, and 69%, respectively. Being a physician, having more work experience, having a higher age, working in tertiary care settings, were key factors for higher knowledge (p < 0.001). The correlation coefficient showed significant positive correlation between attitude- perception (r = 0.560, p < 0.001). CONCLUSION: We have observed average knowledge of HCPs. Therefore, we recommend time to time education campaigns and workshops in highly endemic CCHF regions to be launched by health ministries and HCPs, in particular nurses, encouraged to follow authentic academic sources of information to prevent nosocomial transmission.

COVID-19 Repercussions: Office and Residential Emissions in Pakistan.

The purpose of this study is to find empirical evidence on whether work from home or residential emissions reduces office emissions. Based on existing research the study supports that there are short-term effects on office emissions, i.e., carbon emissions do not outshine the long-term effects. The shift from offices to working from home due to COVID-19 regulations meant more people operating from home as maintaining their position in the market was crucial. The potential research area is to understand how this would affect energy usage and carbon emissions. This study has used a before and after mixed approach to collect data from 301 working-from-home employees and 348 top managers who are responsible for monitoring the employees in a work from home setting. Convenience sampling helped collect responses in a timely manner as offices were not allowing visitors and collecting data in person was difficult, so online surveys were conducted. Work from home reduced usage of office equipment, transportation, pollution, etc. The air quality improved considerably but our findings show that the low emissions were only short-lived. This was not a long-term scenario as organizations kept practicing their operations even at home and the emissions stayed in the environment. Future suggestions and implications are also provided. The results give new insights to researchers in the field of sustainability and the environment.

Influence of Rifampicin Pre-treatment on the In vivo Pharmacokinetics of Metoclopramide in Pakistani Healthy Volunteers Following Concurrent Oral Administration.

BACKGROUND: Metoclopramide is metabolized by various cytochrome P450 (CYP) enzymes such as CYP3A4, CYP1A2, CYP2D6, CYP2C9, and CYP2C19. Rifampicin is a non-selective inducer of P-glycoprotein (P-gp) and CYP enzymes such as CYP3A4 and others. OBJECTIVE: This study was aimed at the evaluation of rifampicin's enzyme induction effect on the pharmacokinetic parameters of orally administered metoclopramide. METHOD: This randomized, single-blind, two-phase cross-over pharmacokinetic study separated by a 4-week washout period was conducted at a single center in Pakistan. It involved twelve Pakistani healthy male volunteers (nonsmokers) divided into two groups. In the reference phase, each volunteer received a single oral dose of 20 mg metoclopramide (Maxolon 10 mg, GlaxoSmithKline, Pakistan), while in the rifampicin-treated phase, each volunteer received 600 mg rifampicin once daily for 6 days through oral route. On day 6, metoclopramide (20 mg) was administered 2 hours after the last pretreatment dose of rifampicin. The serial blood samples were collected on predetermined time points (0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, and 18 h) and analyzed using a validated HPLC method for the determination of pharmacokinetic parameters, i.e. Cmax, Tmax, and AUC0-∞ of metoclopramide. The whole study was monitored by an unblinded clinician for the purpose of volunteer's health safety. RESULTS: All the volunteers participated in the study until the end. Twelve healthy Pakistani males having mean age 26.0 (range 20.6-34.1) years and body mass index 25.1 (range 16.2-31.5) kg/m2 were included in this study after taking written informed consent. Rifampicin significantly (P<0.05) decreased the mean Cmax, AUC0-∞ and T1/2 of metoclopramide by 35%, 68%, and 44%, respectively. The laboratory tests did not reveal any significant change in the biochemical, physical, hematological, or urinalytical values before and after metoclopramide treatment. None of the volunteers complained of any discomfort during the study. CONCLUSION: Rifampicin noticeably decreased the concentration of plasma metoclopramide. These results give in vivo confirmation of the CYP3A4 involvement in the metoclopramide metabolism, in addition to CYP2D6. Therefore, metoclopramide pharmacokinetics may be clinically affected by rifampicin and other potent enzyme inducers.

Development and in vitro evaluation of (ß-cyclodextrin-g-methacrylic acid)/Na+-montmorillonite nanocomposite hydrogels for controlled delivery of lovastatin.

Background: Hyperlipidemia is the elevation of low density lipoprotein levels resulting in fat deposites in arteries and their hardening and blockage.  It is the leading cause of several life threatening pathological conditions like hypertension, cardiovascular diseases, diabetes etc. Purpose: The objective of this study was to prepare and optimize nontoxic, biocompatible ß-CD-g-MAA/Na+-MMT nanocomposite hydrogels with varying content of polymer, monomer and montmorillonite. Moreover, lipid lowering potentials were determined and compared with other approaches. Methods: ß-CD-g-MAA/Na+-MMT nanocomposite hydrogels (BM-1 to BM9) were prepared through free radical polymerization by using  ß-CD  as polymer, MAA as monomer, MBA as crosslinker and montmorillonite as clay. Developed networks were evaluated for FTIR, DSC, TGA, PXRD, SEM, sol-gel fraction (%), swelling studies, antihyperlipidemic studies and toxicity studies. Results: Optimum swelling (94.24%) and release (93.16%) were obtained at higher pH values. Based on R2 and "n" value LVT release followed zero order kinetics with Super Case II transport release mechanism, respectively. Tensile strength and elongation at break were found to be 0.0283MPa and 94.68%, respectively. Gel fraction was between 80.55 - 98.16%. Antihyperlipidemic studies revealed that LDL levels were markedly reduced from 522.24 ± 21.88mg/dl to 147.63 ± 31.5mg/dl. Toxicity studies assured the safety of developed network. Conclusion: A novel pH responsive crosslinked network containing ß-CD - g - poly (methacrylic acid) polymer and MMT was developed and optimized with excellent mechanical, swelling and release properties and lipid lowering potentials.

A randomized control trial of primary care-based management of type 2 diabetes by a pharmacist in Pakistan.

BACKGROUND: The role of a pharmacist in primary health care settings of Pakistan is still obscure. Thus, we aimed to demonstrate the pharmacist-led improvements in glycemic, blood pressure and lipid controls in type 2 diabetes mellitus (T2DM) patients of Lahore, Pakistan. METHODS: The first open label, randomized control trial conducted at a primary health care facility of Lahore, Pakistan by enrolling 244 uncontrolled type 2 diabetes (hemoglobin A1 c, (HbA1c); 10.85 ± 1.74) patients. The pharmacological intervention included identification of drug related problems, drug interactions, change in dose, frequency and therapy switches in collaboration with physician, while non-pharmacological intervention consisted of diet, lifestyle and behavior counseling. Outcome measures were glycemic (HbA1c), blood pressure and lipid controls. RESULTS: In intra-group comparison, compared to control arm (C, n = 52), subjects in the intervention arm (I, n = 83) demonstrated significant differences in process outcome measures; baseline vs final, such as HbA1c (C; 10.3 ± 1.3 vs 9.7 ± 1.3, p <  0.001, I; 10.9 ± 1.7 vs 7.7 ± 0.9, p <  0.0001), systolic blood pressure (SBP) (C; 129.9 ± 13.9 vs 136 ± 7.1, p = 0.0001, I; 145 ± 20.4 vs 123.9 ± 9.9 mmHg, p <  0.0001), diastolic blood pressure (DBP) (C; + 4, p = 0.03, I; - 7 mmHg, p <  0.0001), cholesterol (C; 235.8 ± 57.7 vs 220.9 ± 53.2, p = 0.15, I; 224 ± 55.2 vs 153 ± 25.9 mg/dL, p < 0.0001), triglycerides (C; 213.2 ± 86.6 vs 172.4 ± 48.7, p = 0.001, I; 273 ± 119.4 vs 143 ± 31.6 mg/dL, p < 0.0001) and estimated glomerular filtration rate (eGFR) (C; 77.5 ± 18.6 vs 76 ± 14.2, p = 0.5, I; 69.4 ± 21.3 vs 93.8 ± 15.2 ml/min/1.73m2, p < 0.0001). Likewise, inter-group improvements were more significant in the subjects of intervention group at final follow up in comparison to control for various process outcome measures; HbA1c (p < 0.001), SBP (p < 0.0001), DBP (p = 0.02), cholesterol (p < 0.0001), triglycerides (p < 0.0001), SCr (p < 0.001), eGFR (p < 0.001). Moreover, both male and female subjects exhibited similar responses towards intervention with similar improvements in outcome measures. CONCLUSION: These data suggested that pharmacist intervention in collaboration with physician in primary health care settings may result in significant improvements in glycemic, blood pressure and lipid controls in Pakistani population. TRIAL REGISTRATION: The trial was registered retrospectively with International Standard Registered Clinical/soCial sTudy Number (ISRCTN) registry on July 26, 2017 under nutritional, metabolic, endocrine category with assigned registration # ISRCTN22657497 and can be assessed at https://doi.org/10.1186/ISRCTN22657497.
