Effects of sex and hydration status on kappa opioid receptor-mediated diuresis in rats.

Understanding the function of the kappa opioid receptor (KOP) is crucial for the development of novel therapeutic interventions that target KOP for the treatment of pain, stress-related disorders and other indications. Activation of KOP produces diuretic effects in rodents and man. Sex is a vital factor to consider when assessing drug response in pre-clinical and clinical studies. In this study, the diuretic effect of the KOP agonist, U50488 (1-10 mg/kg), was investigated in both adult female and male Wistar rats that were either normally hydrated or water-loaded. The KOP antagonist norbinaltorphimine (norBNI, 10 mg/kg) was administered 24 h prior to U50488 to confirm the involvement of KOP. U50488 elicited a significant diuretic response at doses ≥ 3 mg/kg in both female and male rats independent of hydration status. U50488 diuretic effects were inhibited by norBNI pre-administration. Water-loading reduced data variability for urine volume in males, but not in females, compared with normally hydrated rats. Sex differences were also evident in U50488 eliciting a significant increase in sodium and potassium ion excretion only in males. This may suggest different mechanisms of U50488 diuretic action in males where renal excretion mechanisms are directly affected more than in females.

Adapting an evidence-based, home cardiac rehabilitation programme for people with heart failure and their caregivers to the Danish context: DK:REACH-HF study.

AIMS: Adapting interventions with an existing evidence base offers a more efficient approach than development of a new intervention. The aim of this study was to describe the process of adapting a home-based cardiac rehabilitation (CR) programme (REACH-HF) intervention originally developed in the United Kingdom for people with heart failure (HF) to the Danish health system - the 'DK:REACH-HF' programme. METHODS AND RESULTS: We followed methodological framework for the conduct and reporting of studies adapting interventions, utilizing documentary analysis, qualitative interviews, stakeholder consultations, and mapping of the Danish policy context. Our study found broad support for the REACH-HF intervention as an alternative to existing centre-based CR. We also identified three key areas of adaptation for the Danish context. First, reduce the word-count of the intervention's resources by linking to existing publicly available CR materials. Second, whilst retaining REACH-HF core components, adapt its content and delivery to reflect differences between Denmark and United Kingdom. Thirdly, to develop a digital version of the intervention. CONCLUSION: Using an evidence-based approach, we successfully adapted the REACH-HF intervention to the context of the Danish healthcare setting, maintaining core components of the original intervention, and developing both a paper based and digital version of the programme material. To inform scaled national implementation of the DK:REACH-HF programme, we seek to undertake a pilot study to test the adapted intervention materials feasibility and acceptability to healthcare practitioners, patients, and their caregivers and confirm the positive impact on the outcomes of HF patients and caregivers.

Caregiver presence in a home-based cardiac rehabilitation programme improves the health-related quality of life of patients with heart failure.

Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) is a home-based cardiac rehabilitation intervention designed for patients with heart failure and their caregivers. We present a pooled analysis of patients >18 years with a confirmed diagnosis of HF recruited to two REACH-HF randomized controlled trials. Where identified by patients and consented to participate, caregivers were randomly assigned with patients to receive the REACH-HF intervention plus usual care or usual care alone. Our analysis demonstrated that compared to control group, the REACH-HF group had a greater gain in their disease-specific health-related quality of life at follow-up.

Guest-host Relationship of Cyclodextrin and its Pharmacological Benefits.

Many methods, including solid dispersion, micellization, and inclusion complexes, have been employed to increase the solubility of potent drugs. Beta-cyclodextrin (ßCD) is a cyclic oligosaccharide consisting of seven glucopyranoside molecules, and is a widely used polymer for formulating soluble inclusion complexes of hydrophobic drugs. The enzymatic activity of Glycosyltransferase or α-amylase converts starch or its derivatives into a mixture of cyclodextrins. The ßCD units are characterized by α -(1-4) glucopyranose bonds. Cyclodextrins possess certain properties that make them very distinctive because of their toroidal or truncated cage-like supramolecular configurations with multiple hydroxyl groups at each end. This allowed them to encapsulate hydrophobic compounds by forming inclusion complexes without losing their solubility in water. Chemical modifications and newer derivatives, such as methylated ßCD, more soluble hydroxyl propyl methyl ßCD, and sodium salts of sulfobutylether-ßCD, known as dexolve® or captisol®, have envisaged the use of CDs in various pharmaceutical, medical, and cosmetic industries. The successful inclusion of drug complexes has demonstrated improved solubility, bioavailability, drug resistance reduction, targeting, and penetration across skin and brain tissues. This review encompasses the current applications of ß-CDs in improving the disease outcomes of antimicrobials and antifungals as well as anticancer and anti-tubercular drugs.

Research priorities relating to the delivery of cardiovascular prevention and rehabilitation programmes: results of a modified Delphi process.

OBJECTIVE: The purpose of this British Association for Cardiovascular Prevention and Rehabilitation (BACPR) research priority setting project (PSP) was to identify a top 10 list of priority research questions for cardiovascular prevention and rehabilitation (CVPR). METHODS: The PSP was facilitated by the BACPR clinical study group (CSG), which integrates as part of the British Heart Foundation Clinical Research Collaborative. Following a literature review to identify unanswered research questions, modified Delphi methods were used to engage CVPR-informed expert stakeholders, patients, partners and conference delegates in ranking the relevance of research questions during three rounds of an anonymous e-survey. In the first survey, unanswered questions from the literature review were ranked and respondents proposed additional questions. In the second survey, these new questions were ranked. Prioritised questions from surveys 1 and 2 were incorporated in a third/final e-survey used to identify the top 10 list. RESULTS: From 459 responses across the global CVPR community, a final top 10 list of questions were distilled from an overall bank of 76 (61 from the current evidence base and a further 15 from respondents). These were grouped across five broad categories: access and remote delivery, exercise and physical activity, optimising programme outcomes, psychosocial health and impact of the pandemic. CONCLUSIONS: This PSP used a modified Delphi methodology to engage the international CVPR community to generate a top 10 list of research priorities within the field. These prioritised questions will directly inform future national and international CVPR research supported by the BACPR CSG.

Cardiac rehabilitation for heart failure: 'Cinderella' or evidence-based pillar of care?

Cardiac rehabilitation remains the 'Cinderella' of treatments for heart failure. This state-of-the-art review provides a contemporary update on the evidence base, clinical guidance, and status of cardiac rehabilitation delivery for patients with heart failure. Given that cardiac rehabilitation participation results in important improvements in patient outcomes, including health-related quality of life, this review argues that an exercise-based rehabilitation is a key pillar of heart failure management alongside drug and medical device provision. To drive future improvements in access and uptake, health services should offer heart failure patients a choice of evidence-based modes of rehabilitation delivery, including home, supported by digital technology, alongside traditional centre-based programmes (or combinations of modes, 'hybrid') and according to stage of disease and patient preference.

Home-based cardiac rehabilitation and physical activity in people with heart failure: a secondary analysis of the REACH-HF randomised controlled trials.

OBJECTIVES: To quantify the impact of a home-based cardiac rehabilitation intervention (Rehabilitation Enablement in Chronic Heart Failure (REACH-HF)) on objectively assessed physical activity (PA) of patients with heart failure (HF) and explore the extent by which patient characteristics are associated with a change in PA. DESIGN: Secondary analysis of randomised controlled trial data. SETTING: Five centres in the UK. PARTICIPANTS: 247 patients with HF (mean age 70.9±10.3 years; 28% women). INTERVENTIONS: REACH-HF versus usual care (control). PRIMARY AND SECONDARY OUTCOME MEASURES: PA was assessed over 7 days via GENEActiv triaxial accelerometer at baseline (pre-randomisation), post-intervention (4 months) and final follow-up (6-12 months). Using HF-specific intensity thresholds, intervention effects (REACH-HF vs control) on average min/day PA (inactivity, light PA and moderate-to-vigorous PA (MVPA)) over all days, week days and weekend days were examined using linear regression analysis. Multivariable regression was used to explore associations between baseline patient characteristics and change in PA. RESULTS: Although there was no difference between REACH-HF and control groups in 7-day PA levels post-intervention or at final follow-up, there was evidence of an increase in weekday MVPA (10.9 min/day, 95% CI: -2.94 to 24.69), light PA (26.9 min/day, 95% CI: -0.05 to 53.8) and decreased inactivity (-38.31 min/day, 95% CI: -72.1 to -4.5) in favour of REACH-HF. Baseline factors associated with an increase in PA from baseline to final follow-up were reduced MVPA, increased incremental shuttle walk test distance, increased Hospital Anxiety and Depression Scale anxiety score and living with a child >18 years (p<0.05). CONCLUSIONS: While participation in the REACH-HF home-based cardiac rehabilitation intervention did not increase overall weekly activity, patient's behaviour patterns appeared to change with increased weekday PA levels and reduced inactivity. Baseline PA levels were highly predictive of PA change. Future focus should be on robust behavioural changes, improving overall levels of objectively assessed PA of people with HF. TRIAL REGISTRATION NUMBERS: ISRCTN78539530 and ISRCTN86234930.

Home-based cardiac rehabilitation for people with heart failure and their caregivers: a mixed-methods analysis of the roll out an evidence-based programme in Scotland (SCOT:REACH-HF study).

AIMS: Alternative models of cardiac rehabilitation (CR) are required to improve CR access and uptake. Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) is a comprehensive home-based rehabilitation and self-management programme, facilitated by trained health professionals, for people with heart failure (HF) and their caregivers. REACH-HF was shown to be clinically effective and cost-effective in a multi-centre randomized trial. The SCOT:REACH-HF study assessed implementation of REACH-HF in routine clinical practice in NHS Scotland. METHODS AND RESULTS: A mixed-method implementation study was conducted across six regional Health Boards. Of 136 people with HF and 56 caregivers recruited, 101 people with HF and 26 caregivers provided 4-month follow-up data, after participating in the 12-week programme. Compared with baseline, REACH-HF participation resulted in substantial gains in the primary outcome of health-related quality of life, as assessed by the Minnesota Living with Heart Failure Questionnaire (mean difference: -9.8, 95% CI: -13.2 to -6.4, P < 0.001). Improvements were also seen in secondary outcomes (PROM-CR+; EQ-5D-5L; Self-Care of Heart Failure Index (SCHFI) domains of maintenance and symptom perception; Caregiver Contribution to Self-Care domains of symptom perception and management). Twenty qualitative interviews were conducted with 11 REACH-HF facilitators, five supporting clinicians, and four national stakeholders. Interviewees were largely positive about REACH-HF, considering it to have 'filled a gap' where centre-based CR was not an option. Key issues to support future roll-out were also identified. CONCLUSION: Our findings support wider roll-out of REACH-HF as an alternative to centre-based models, to improve CR access and uptake for people with HF.

Why Do so Few People with Heart Failure Receive Cardiac Rehabilitation?

Many people with heart failure do not receive cardiac rehabilitation despite a strong evidence base attesting to its effectiveness, and national and international guideline recommendations. A more holistic approach to heart failure rehabilitation is proposed as an alternative to the predominant focus on exercise, emphasising the important role of education and psychosocial support, and acknowledging that this depends on patient need, choice and preference. An individualised, needs-led approach, exploiting the latest digital technologies when appropriate, may help fill existing gaps, improve access, uptake and completion, and ensure optimal health and wellbeing for people with heart failure and their families. Exercise, education, lifestyle change and psychosocial support should, as core elements, unless contraindicated due to medical reasons, be offered routinely to people with heart failure, but tailored to individual circumstances, such as with regard to age and frailty, and possibly for recipients of cardiac implantable electronic devices or left ventricular assist devices.

Recent advances in biodecolorization and biodegradation of environmental threatening textile finishing dyes.

Organic nature of dyes and their commercially made products are widely utilized in many industries including paper, cosmetics, pharmaceuticals, photography, petroleum as well as in textile manufacturing. The textile industry being the top most consumer of a large variety of dyes during various unit processes operation generates substantial amount of wastewater; hence, nominated as "Major Polluter of Potable Water". The direct discharge of such effluents into environment poses serious threats to the functioning of biotic communities of natural ecosystems. The detection of these synthetic dyes is considered as relatively easy, however, it is extremely difficult to completely eliminate them from wastewater and freshwater ecosystems. Aromatic chemical structure seems to be the main reason behind low biodegradability of these dyes. Currently, various physiochemical and biological methods are employed for their remediation. Among them, microbial degradation has attracted greater attention due to its sustainability, high efficiency, cost effectiveness, and eco-friendly nature. The current review presents recent advances in biodegradation of industrial dyes towards a sustainable and tangible technological innovative solutions as an alternative to existing conventional physicochemical treatment processes.

Barriers and facilitators to implementation of a home-based cardiac rehabilitation programme for patients with heart failure in the NHS: a mixed-methods study.

OBJECTIVES: This study aimed to identify barriers to, and facilitators of, implementation of the Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) programme within existing cardiac rehabilitation services, and develop and refine the REACH-HF Service Delivery Guide (an implementation guide cocreated with healthcare professionals). REACH-HF is an effective and cost-effective 12-week home-based cardiac rehabilitation programme for patients with heart failure. SETTING/PARTICIPANTS: In 2019, four early adopter 'Beacon Sites' were set up to deliver REACH-HF to 200 patients. In 2020, 5 online REACH-HF training events were attended by 85 healthcare professionals from 45 National Health Service (NHS) teams across the UK and Ireland. DESIGN: Our mixed-methods study used in-depth semi-structured interviews and an online survey. Interviews were conducted with staff trained specifically for the Beacon Site project, identified by opportunity and snowball sampling. The online survey was later offered to subsequent NHS staff who took part in the online REACH-HF training. Normalisation Process Theory was used as a theoretical framework to guide data collection/analysis. RESULTS: Seventeen healthcare professionals working at the Beacon Sites were interviewed and 17 survey responses were received (20% response rate). The identified barriers and enablers included, among many, a lack of resources/commissioning, having interest in heart failure and working closely with the clinical heart failure team. Different implementation contexts (urban/rural), timing (during the COVID-19 pandemic) and factors outside the healthcare team/system (quality of the REACH-HF training) were observed to negatively or positively impact the implementation process. CONCLUSIONS: The findings are highly relevant to healthcare professionals involved in planning, delivering and commissioning of cardiac rehabilitation for patients with heart failure. The study's main output, a refined version of the REACH-HF Service Delivery Guide, can guide the implementation process (eg, designing new care pathways) and provide practical solutions to overcoming common implementation barriers (eg, through early identification of implementation champions).

A pragmatic effectiveness-implementation study comparing trial evidence with routinely collected outcome data for patients receiving the REACH-HF home-based cardiac rehabilitation programme.

BACKGROUND: Cardiac rehabilitation for heart failure continues to be greatly underused worldwide despite being a Class I recommendation in international clinical guidelines and uptake is low in women and patients with mental health comorbidities. METHODS: Rehabilitation EnAblement in CHronic Heart Failure (REACH-HF) programme was implemented in four UK National Health Service early adopter sites ('Beacon Sites') between June 2019 and June 2020. Implementation and patient-reported outcome data were collected across sites as part of the National Audit of Cardiac Rehabilitation. The change in key outcomes before and after the supervised period of REACH-HF intervention across the Beacon Sites was assessed and compared to those of the intervention arm of the REACH-HF multicentre trial. RESULTS: Compared to the REACH-HF multicentre trial, patients treated at the Beacon Site were more likely to be female (33.8% vs 22.9%), older (75.6 vs 70.1), had a more severe classification of heart failure (26.5% vs 17.7%), had poorer baseline health-related quality of life (MLHFQ score 36.1 vs 31.4), were more depressed (HADS score 6.4 vs 4.1) and anxious (HADS score 7.2 vs 4.7), and had lower exercise capacity (ISWT distance 190 m vs 274.7 m). There appeared to be a substantial heterogeneity in the implementation process across the four Beacon Sites as evidenced by the variation in levels of patient recruitment, operationalisation of the REACH-HF intervention and patient outcomes. Overall lower improvements in patient-reported outcomes at the Beacon Sites compared to the trial may reflect differences in the population studied (having higher morbidity at baseline) as well as the marked challenges in intervention delivery during the COVID-19 pandemic. CONCLUSION: The results of this study illustrate the challenges in consistently implementing an intervention (shown to be clinically effective and cost-effective in a multicentre trial) into real-world practice, especially in the midst of a global pandemic. Further research is needed to establish the real-world effectiveness of the REACH-HF intervention in different populations.

Nanoencapsulation of Polyphenols as Drugs and Supplements for Enhancing Therapeutic Profile - A Review.

Polyphenolic phytoconstituents have been widely in use worldwide for ages and are categorised as secondary metabolites of plants. The application of polyphenols such as quercetin, resveratrol, curcumin as nutritional supplements has been researched widely. The use of polyphenols and specifically quercetin, for improving memory and mental endurance has shown significant effects among rats. Even though similar results have not been resonated among humans, but preclinical results have encouraged researchers to explore other polyphenols to study the effects as supplements among athletes. The phytopharmacological research has elucidated the use of natural polyphenols to prevent and treat various physiological and metabolic disorders owing to their free radical scavenging properties, anti-inflammatory, anti-cancer, and immunomodulatory effects. In- -spite of the tremendous pharmacological profile, one of the most dominant problem regarding the use of polyphenolic compounds is their low bioavailability. Nanonization is considered as one of the most prominent approaches among many. This article aims to review and discuss the molecular mechanisms of recently developed nanocarrier-based drug delivery systems for polyphenols and their application as drugs and supplements. Nanoformulations of natural polyphenols as bioactive agents, such as quercetin, kaempferol, fisetin, rutin, hesperetin, and naringenin epigalloccatechin- 3-gallate, genistein, ellagic acid, gallic acid, chlorogenic acid, ferulic acid, curcuminoids, and stilbenes is expected to have better efficacy. These delivery systems are expected to provide higher penetrability of polyphenols at cellular levels and exhibit a controlled release of the drugs. It is widely accepted that natural polyphenols do demonstrate significant therapeutic effects. However, the hindrances in their absorption, specificity, and bioavailability can be overcome using nanotechnology.

The role of cardiac rehabilitation in improving cardiovascular outcomes.

Cardiac rehabilitation is a complex intervention that seeks to improve the functional capacity, wellbeing and health-related quality of life of patients with heart disease. A substantive evidence base supports cardiac rehabilitation as a clinically effective and cost-effective intervention for patients with acute coronary syndrome or heart failure with reduced ejection fraction and after coronary revascularization. In this Review, we discuss the major contemporary challenges that face cardiac rehabilitation. Despite the strong recommendation in current clinical guidelines for the referral of these patient groups, global access to cardiac rehabilitation remains poor. The COVID-19 pandemic has contributed to a further reduction in access to cardiac rehabilitation. An increasing body of evidence supports home-based and technology-based models of cardiac rehabilitation as alternatives or adjuncts to traditional centre-based programmes, especially in low-income and middle-income countries, in which cardiac rehabilitation services are scarce, and scalable and affordable models are much needed. Future approaches to the delivery of cardiac rehabilitation need to align with the growing multimorbidity of an ageing population and cater to the needs of the increasing numbers of patients with cardiac disease who present with two or more chronic diseases. Future research priorities include strengthening the evidence base for cardiac rehabilitation in other indications, including heart failure with preserved ejection fraction, atrial fibrillation and congenital heart disease and after valve surgery or heart transplantation, and evaluation of the implementation of sustainable and affordable models of delivery that can improve access to cardiac rehabilitation in all income settings.

Nanotechnological Advances in the Treatment of Epilepsy.

Epilepsy is known as one of the major challenges for medical science. The sudden appearance of a seizure has been a significant health emergency as it may lead to further complications. Although key advancements have been achieved in terms of pharmacological approaches for epilepsy, many issues remain uncertain. Lipid carriers have been at the forefront, especially in neurodegenerative diseases, such as epilepsy, Alzheimer's, dementia, etc. The blood-brain barrier still appears to be a major impediment in the successful treatment of epileptic seizures. This is mainly due to the limited bioavailability of most anti-convulsant drugs. The present review encompasses the issues underlying the current approach for epilepsy drug treatment and highlights the newer, novel, and more precise drug delivery system to manage seizures. The advantage of using a lipidbased delivery system is its superior absorption in the brain cells. Ample evidence shows that reducing the particle size also infuses the drug easily through the blood-brain barrier. The application of liposomes, polymeric nanoparticles, metallic nanoparticles, and solid lipid nanoparticles for the treatment and management of epilepsy has been highlighted in the present review. This review provides an overview of the current status of the treatment and recent advances in the treatment of epilepsy.

An analysis of antidepressant prescribing trends in England 2015-2019.

Background Growing concerns about the impact of coronavirus disease 2019 (COVID-19) will likely lead to increased mental health diagnoses and treatment. To provide a pre-COVID-19 baseline, we have examined antidepressant prescribing trends for 5 years preceding COVID-19. Methods A retrospective analysis of anonymised data on medicines prescribed by GPs in England from the Open-Prescribing Database (January 2015 to December 2019) identified the 10 most prescribed antidepressant and, for comparison, cardiovascular medicines. Results Prescription items for the 10 most prescribed antidepressants rose 25% from 58 million (2015) to 72 million (2019). Citalopram was the most prescribed antidepressant; prescriptions for sertraline rose fastest at 2 million items year on year. Over the same period, costs for antidepressant prescribing fell 27.8%. Across all Clinical Commissioning Groups (CCGs) in England, antidepressant prescribing levels, adjusted for population were positively correlated with the index of multiple deprivation (IMD) score. In comparison, prescribing for the top 10 most prescribed cardiovascular medicines increased by 2.75% from 207 million (2015) to 213 million (2019) items. Limitations Anonymised data in the Open-Prescribing Database means no patient diagnoses or treatment plans are linked to this data. Conclusion Antidepressant prescribing, particularly sertraline, is increasing. Prescribing is higher in more deprived regions, but costs are falling to < 2% of all items prescribed. Absolute numbers of prescriptions for cardiovascular medicines are higher, likely reflecting the greater prevalence of cardiovascular disease, and are rising more slowly. This study will enable future work to look at the impact of COVID-19 on prescribing for mental health.

Food insecurity and mental health of women during COVID-19: Evidence from a developing country.

BACKGROUND: This study examines the association between food insecurity and mental health of women during the COVID-19 pandemic in a resource poor setting. MATERIALS AND METHODS: Data were collected at two time-points (wave 1 and 2) from 2402 women, one per household, participating in a larger study during extended COVID-19 lockdown in the rural areas of the southwest region of Bangladesh. The primary outcome of the analyses is the association between food insecurity, measured using the Food Insecurity Experience Scale (FIES), and stress level, measured using the Perceived Stress Scale (PSS), for women during the lockdown. General awareness about COVID-19 and attitude towards prescribed preventive measures were also measured since COVID-19 health concerns could exacerbate food insecurity. RESULTS: An individual-level evaluation of the effect of wave 2 FIES score on PSS score showed that worsening of the food security status increasing the stress level of the participants (95% CI: 1.61; 2.13; p-value: <0.001). Additionally, a significant negative association was observed between the PSS score and change in food security status between the two waves (Coefficient: -1.15, 95% CI: -1.30; -0.99, p-value: <0.001), indicating that deterioration in food security status over the pandemic period increasing the stress level. At the village level, the results showed a similar pattern. General awareness around ways coronavirus spreads was high, yet there were misperceptions at a higher level. Maintaining hand hygiene, wearing face masks outside the home, and going outside only when necessary were widely practised. Fewer respondents could maintain a 1.5-metre distance from others in the outside and maintained cough and sneeze etiquette. CONCLUSION: The results indicate a higher stress level, a potential contributor to poor mental health, as food insecurity deteriorated. Policy initiatives in ameliorating immediate food insecurity during crises, improving long-term wellbeing, and expanding the reach of mental health support are warranted.

Knowledge, attitude, perception of Muslim parents towards vaccination in Malaysia.

Malaysia is a predominant Muslim country and the recent surge in vaccine-preventable disease enticed us to conduct a survey to measure the Knowledge, Attitude and Perception of Muslim parents toward vaccination process. The data were collected under four segments such as demography, Knowledge, Attitude and Perception. The questionnaire had high internal consistency (0.823) for Cronbach's alpha. The sociodemographic determinants such as marital status (OR = 1.12; 0.91-1.38;p < .05), education level (college OR = 1.35; 1.12-1.64;p < .05, secondary OR = 1.22; 1.01-1.47;p < .05) and the occupation of parents (OR = 1.25; 1.07-1.45;p < .05) were observed affecting the Knowledge score significantly. Majority of Malaysian Muslim parents believed that "vaccine is not prohibited in Islam" and most of them also rejected the belief that "all vaccines are non halal and hence should be avoided". None of the sociodemographic determinants significantly affected the Attitude and Perception score of the Muslim parents. It was observed that the Attitude and Perception score did not establish any association with any of the socio-demographic determinants and hence the null hypothesis that Malaysian Muslim parents had positive Attitude and good Perception toward vaccination process was accepted.
