ABSTRACT

Background: The relationship between adult ADHD symptoms in People with Multiple Sclerosis (PwMS) is understudied. This study aimed to answer two questions: are PwMS more likely to experience higher ADHD symptoms versus healthy subjects? And what are the correlates of severe ADHD symptoms in PwMS? Methods: This study followed a cross-sectional design with predefined inclusion criteria. The Adult ADHD Self-Report Scale-V1.1 (ASRS) was used to assess the ADHD symptoms severity. Results: Data were analyzed from 171 PwMS and 200 controls. Regression analysis revealed that PwMS were at a significantly (B = 3.05, t = 2.24, 95% CI = 0.37-5.73, p = 0.02) higher risk to report higher ADHD scores versus controls. In addition, PwMS with relapses in the last 6 months and PwMS reporting smartphone addiction were at a significantly higher risk for severe ADHD (B = 7.19, t = 269, 95% CI = 1.91-12.48, p = 0.008) and (B = 9.18, t = 3.47, 95% CI = 3.97-14.41, p = 0.001), respectively. In conclusion, diagnosis with MS in our study was identified as a risk for higher ADHD symptoms. Conclusions: Further research is required to establish this relationship, and holistic medical and psychological interventions are required to improve the cognitive status of PwMS.

ABSTRACT

OBJECTIVE: This cross-sectional study aimed to assess Jordanian community pharmacists' awareness, perception, and roles concerning emergency contraceptives provision. STUDY DESIGN: We administered a structured questionnaire to community pharmacists in Jordan using convenience sampling. The questionnaire included sections on demographic information, knowledge about emergency contraceptives, perception towards emergency contraceptive, and prior experience in emergency contraceptives provision. RESULTS: A total of 299 community pharmacists responded to the study. Most pharmacists had a Pharm D/BPharm degree (94.6%) and worked in independent community pharmacies (75.6%). While pharmacists demonstrated relatively high knowledge scores regarding emergency contraception, with a median score of 10 out of 14, misconceptions persisted, particularly regarding the mechanism of action and side effects of emergency contraception. Pharmacists expressed mixed perceptions regarding emergency contraception, with a significant proportion advocating for prescription-only access (76.6%) and expressing ethical reservations (48.2%). Only 38.1% reported prior experience in emergency contraceptives provision. Regression analyses revealed that attendance at emergency contraceptives-focused workshops significantly increased the likelihood of pharmacists providing emergency contraceptives (Adjusted Odds Ratio=2.569, p = 0.001). CONCLUSIONS: Jordanian community pharmacists exhibit readiness to provide emergency contraceptives, but persistent misconceptions and regulatory barriers hinder optimal provision. Targeted educational interventions, particularly through workshops, are crucial in enhancing pharmacists' knowledge and promoting emergency contraceptives provision. IMPLICATIONS: Responding pharmacists often reported the misconception that emergency contraceptives can cause abortion. Also, some pharmacists expressed religious or moral objections to prescribing oral emergency contraceptives. Thus, this study underscores the importance of receiving comprehensive training on ethical and religious considerations in healthcare practice.

ABSTRACT

OBJECTIVE: This study investigated the prevalence and correlates of fibromyalgia and insomnia in a sample of Women with Multiple Sclerosis (WMS). METHODS: The study was cross-sectional in design and recruited a sample of 163 women with Relapsing-Remitting Multiple Sclerosis (RRMS). Fibromyalgia was assessed using the Patient Self-Report Survey (PSRS), following criteria outlined by the American College of Rheumatology. Insomnia was measured using the Arabic version of the Insomnia Severity Index (ISI-A). RESULTS: The prevalence of fibromyalgia and insomnia was 28.2% (n = 46) and 46.3% (n = 76), respectively. Multivariate analyses were used to determine significant independent correlates. Fibromyalgia was associated with age above 40 years (OR = 2.29, 95% CI = 1.01-5.18, P = .04), high school education (OR = 3.69, 95% CI = 1.62-8.37, P = .002), and non-use of analgesics (OR = .02, 95% CI = .004-.21, P = .001). Insomnia symptoms were significantly associated only with age above 40 years (OR = 2.16, 95% CI = 1.16-4.04, P = .01). CONCLUSION: These findings highlight the need for increased attention by primary care physicians towards diagnosing and treating fibromyalgia and insomnia among women with RRMS in Jordan, particularly among older women.

ABSTRACT

This study investigated parental attitudes toward childhood vaccination in Jordan, focusing on acceptance, concerns, and perceptions. A cross-sectional survey conducted from January to February 2024 included 939 parents. Findings indicated that 85.4% (n = 802) of respondents received the COVID-19 vaccine, while only 25% (n = 229) vaccinated their children. Concerns regarding vaccine safety and efficacy were prevalent, with 63.9% (n = 600) expressing worries about side effects and 46.9% (n = 440) trusting immunization programs. Post-pandemic, 34% (n = 319) reported a more negative attitude. Logistic regression showed parents not vaccinating their children against COVID-19 were significantly less likely to exhibit positive attitudes toward childhood vaccination (OR = 0.412, p < 0.001). Older participants were more inclined toward negativity post-pandemic (OR = 1.031, p = 0.007). In conclusion, parental attitudes shifted post-COVID-19, reflecting hesitancy and decreased trust. Addressing concerns and restoring confidence are crucial, especially for children's health. Education through healthcare providers and dispelling social media misinformation are essential. Implementing strategies to enhance post-pandemic vaccine acceptance is imperative for preventing outbreaks of vaccine-preventable diseases.

ABSTRACT

(1) Background: Attention Deficit Hyperactivity Disorder (ADHD)-like symptoms and insomnia are closely related. The present study examined whether the use of different sleep aids was related to severe ADHD-like symptoms in Jordanian adults screened for insomnia. (2) Methods: This cross-sectional study used predefined inclusion criteria. The severity of ADHD was assessed using the validated Arabic version of the Adult ADHD Self-Report Scale. (3) Results: Data were analyzed from 244 subjects who met the inclusion criteria for severe insomnia, of which 147 (65.3%) reported not using any sleep aid, 50 (22.3%) reported using homeopathy remedies as sleep aids, and 41 (18.3%) reported using over-the-counter antihistamines as sleep aids. Regression analysis revealed that the use of such sleep aids-namely, "homeopathy herbal remedies" and "over-the-counter antihistamines"-was not associated (p > 0.05) with ADHD-like symptoms. However, "age above 31 years old" was significantly associated (B = -3.95, t = -2.32, p = 0.002) with lower ADHD severity, while the "diagnosis with chronic diseases" was significantly associated (B = 4.15, t = 1.99, p = 0.04) with higher ADHD severity. (4) Conclusions: Sleep aids are not associated with ADHD-like symptoms in adults. More research is required to uncover the risk factors for adult ADHD, especially insomnia.

ABSTRACT

BACKGROUND: Antipsychotics, including risperidone (RIS), are frequently indicated for various autism spectrum disorder (ASD) manifestations; however, "actionable" PGx testing in psychiatry regarding antipsychotic dosing and selection has limited applications in routine clinical practice because of the lack of standard guidelines, mostly due to the inconsistency and scarcity of genetic variant data. The current study is aimed at examining the association of RIS effectiveness, according to ABC-CV and CGI indexes, with relevant pharmacokinetics (PK) and pharmacodynamics (PD) genes. METHODS: Eighty-nine ASD children who received a consistent RIS-based regimen for at least 8 weeks were included. The Axiom PharmacoFocus Array technique was employed to generate accurate star allele-predicted phenotypes of 3 PK genes (CYP3A4, CYP3A5, and CYP2D6). Genotype calls for 5 candidate PD receptor genes (DRD1, DRD2, DRD3, HTR2C, and HTR2A) were obtained and reported as wild type, heterozygous, or homozygous for 11 variants. RESULTS: Based on the ABC total score, 42 (47.2%) children were classified as responders, while 47 (52.8%) were classified as nonresponders. Multivariate logistic regression analyses, adjusted for nongenetic factors, suggested nonsignificant impacts of the star allele-predicted phenotypes of all 3 PK genes on improvement in ASD symptoms or CGI scores. However, significant positive or negative associations of certain PD variants involved in dopaminergic and serotonergic pathways were observed with specific ASD core and noncore symptom subdomains. Our significant polymorphism findings, mainly those in DRD2 (rs1800497, rs1799978, and rs2734841), HTR2C (rs3813929), and HTR2A (rs6311), were largely consistent with earlier findings (predictors of RIS effectiveness in adult schizophrenia patients), confirming their validity for identifying ASD children with a greater likelihood of core symptom improvement compared to noncarriers/wild types. Other novel findings of this study, such as significant improvements in DRD3 rs167771 carriers, particularly in ABC total and lethargy/social withdrawal scores, and DRD1 rs1875964 homozygotes and DRD2 rs1079598 wild types in stereotypic behavior, warrant further verification in biochemical and clinical studies to confirm their feasibility for inclusion in a PGx panel. CONCLUSION: In conclusion, we provide evidence of potential genetic markers involved in clinical response variability to RIS therapy in ASD children. However, replication in prospective samples with greater ethnic diversity and sample sizes is necessary.

ABSTRACT

Background: Autism spectrum disorders (ASDs) encompass a broad range of phenotypes characterized by diverse neurological alterations. Genomic studies have revealed considerable overlap between the molecular mechanisms implicated in the etiology of ASD and genes involved in the pharmacokinetic (PK) and pharmacodynamic (PD) pathways of antipsychotic drugs employed in ASD management. Given the conflicting data originating from candidate PK or PD gene association studies in diverse ethnogeographic ASD populations, dosage individualization based on "actionable" pharmacogenetic (PGx) markers has limited application in clinical practice. Additionally, off-label use of different antipsychotics is an ongoing practice, which is justified given the shortage of approved cures, despite the lack of satisfactory evidence for its safety according to precision medicine. This exploratory study aimed to identify PGx markers predictive of risperidone (RIS) exposure in autistic Saudi children. Methods: This prospective cohort study enrolled 89 Saudi children with ASD treated with RIS-based antipsychotic therapy. Plasma levels of RIS and 9-OH-RIS were measured using a liquid chromatography-tandem mass spectrometry system. To enable focused exploratory testing, genotyping was performed with the Axiom PharmacoFocus Array, which included a collection of probe sets targeting PK/PD genes. A total of 720 PGx markers were included in the association analysis. Results: A total of 27 PGx variants were found to have a prominent impact on various RIS PK parameters; most were not located within the genes involved in the classical RIS PK pathway. Specifically, 8 markers in 7 genes were identified as the PGx markers with the strongest impact on RIS levels (p < 0.01). Four PGx variants in 3 genes were strongly associated with 9-OH-RIS levels, while 5 markers in 5 different genes explained the interindividual variability in the total active moiety. Notably, 6 CYP2D6 variants exhibited strong linkage disequilibrium; however, they significantly influenced only the metabolic ratio and had no considerable effects on the individual estimates of RIS, 9-OH-RIS, or the total active moiety. After correction for multiple testing, rs78998153 in UGT2B17 (which is highly expressed in the brain) remained the most significant PGx marker positively adjusting the metabolic ratio. For the first time, certain human leukocyte antigen (HLA) markers were found to enhance various RIS exposure parameters, which reinforces the gut-brain axis theory of ASD etiology and its suggested inflammatory impacts on drug bioavailability through modulation of the brain, gastrointestinal tract and/or hepatic expression of metabolizing enzymes and transporters. Conclusion: Our hypothesis-generating approach identified a broad spectrum of PGx markers that interactively influence RIS exposure in ASD children, which indicated the need for further validation in population PK modeling studies to define polygenic scores for antipsychotic efficacy and safety, which could facilitate personalized therapeutic decision-making in this complex neurodevelopmental condition.

ABSTRACT

Data on the role of CYP2D6 and CYP3A4/5 polymorphisms in relation to risperidone (RIS) pharmacokinetics (PK) in children are relatively limited and inconsistent. This is partially attributable to the limited coverage of CYP2D6 and CYP3A4/5 metabolizer phenotypes, particularly those of poor and ultrarapid metabolizers (PMs and UMs), which has led to calls for studies of populations with a non-European background that may carry variants that are less frequent in Europeans. Children ≤ 18 years old with at least 8 weeks of a RIS-based regimen were recruited from three autism centers in Riyadh, Saudi Arabia. The primary outcomes measured were plasma concentrations of RIS and 9-hydroxyrisperidone (9-OH-RIS) and their dose-adjusted (C/D) ratios as a function of phenotypes and activity score (AS). For accurate DNA genotyping, targeted pharmacogenomic testing with the Axiom PharmacoFocus Array was performed via examination of a broad collection of probesets targeting CYP2D6 and CYP3A4/5 variants. The frequency of genotypes/phenotypes and the impact of their allele translation and phenoconversion-predicted enzyme activity were examined. The final cohort included 83 individuals. The most common CYP2D6 phenotype in our population was normal metabolizers (NMs, 66.3%). Inconsistent with some previous studies, the three phenotypes of intermediate metabolizers (IMs), NMs, and UMs were significantly different in terms of RIS concentration, the RIS/9-OH-RIS ratio, the RIS C/D ratio and the 9-OH-RIS C/D ratio. According to AS analyses, there were statistically significant differences in the RIS concentration (P = 0.013), RIS/9-OH-RIS ratio (P < 0.001) and RIS C/D ratio (P = 0.030) when patients were categorized into AS ≤ 1 vs. AS > 1. None of the CYP3A4/5 star allele translated phenotypes revealed a significant influence on any of the RIS PK parameters. Notably, neither CYP2D6 nor CYP3A4/5 phenotyping demonstrated a significant impact on the total active moiety, suggesting that other gene variants could modulate RIS PK. The study confirmed the previously reported partial impact of the CYP2D6 gene on RIS PK. However, future studies using contemporary genotyping techniques targeting a wide range of variants in other candidate genes must be conducted to further examine their interactive effects on RIS PK and the clinical response.

ABSTRACT

Cancer is the major challenge across world and the adenocarcinoma of prostate malignancy is the second most prevalent male cancer. Various medicinal plants are used for the treatment and management of various cancers. Matricaria chamomilla L., is one of the extensively used Unani medicament for the treatment of various type of diseases. In the current study we evaluated most of the parameters prescribed for drug standardization using pharmacognostic approaches. The 2,2 Diphenyl-1-picryl hydrazyl (DPPH) method was utilized for the analysis of antioxidant activity in the flower extracts of M. chamomilla. Moreover, we analyzed the antioxidant and cytotoxic activity of M. chamomilla (Gul-e Babuna) through in-vitro method. DPPH (2,2-diphenyl-1-picryl-hydrazl-hydrate) method was utilized for the analysis of antioxidant activity in the flower extracts of M. chamomilla. CFU and wound healing assay were performed to determine the anti-cancer activity. The results demonstrated that various extracts of M. chamomilla fulfilled most of the parameters of drug standardization and contained good antioxidant and anticancer activities. The ethyl acetate showed higher anticancer activity followed by aqueous, hydroalcoholic, petroleum benzene and methanol by CFU method. Also, the wound healing assay demonstrated that ethyl acetate extract has more significant effect followed by methanol and petroleum benzene extract on prostate cancer cell line (C4-2). The current study concluded that the extract of M. chamomilla flowers could act as good source of natural anti-cancer compounds.

ABSTRACT

Arrhythmia is an important cause of death after myocardial infarction (MI). Different substances have been evaluated for their anti-arrhythmic effect in MI. This study was performed to evaluate the anti-arrhythmic impacts of crocin in an MI animal model (rat) by estimation of the expression of connexin 43 (Cx43). Fifty male Sprague-Dawley rats were grouped into 5 groups, each composed of 10 rats. The first group was regarded as the normal control group and the second one was considered as the MI group, which was caused by ligation of the left anterior descending artery. The other three groups received crocin 50 or 10 mg/kg/day or metoprolol 100 mg/kg/day for 1 week, following ligation of the left anterior descending artery. Evaluated outcomes were cardiac Cx43 expression, arrhythmia incidence, histological findings, and myocyte resting potential. Crocin-treated MI groups showed a significantly lower arrhythmia score than the non-treated MI group, 10 mg/kg/day (1.85 ± 0.55, p < 0.01) and 50 mg/kg/day (1.70 ± 0.33, p < 0.01). Groups that received crocin 10 mg/kg/day (66.30 ± 2.59, p < 0.01), crocin 50 mg/kg/day (68.10 ± 2.43, p < 0.01), and metoprolol 100 mg/kg/day (-63.54 ± 0.63 mV, p < 0.01) significantly prevented depolarization in comparison with the non-treated MI group. Expression of Cx43 mRNA in crocin 10 mg/kg/day (1.54 ± 0.24, p < 0.01), crocin 50 mg/kg/day (1.73 ± 0.09, p < 0.01), and metoprolol 100 mg/kg/day (1.75 ± 0.14, p < 0.01) treatment groups was significantly higher in comparison with the non-treated MI group. Crocin showed a preventive effect on the arrhythmogenic impact of MI in an experimental model of ischemic injury through an increase in expression of Cx43.

ABSTRACT

BACKGROUND: The world has been battling several vector-borne diseases since time immemorial. Socio-economic marginality, precipitation variations and human behavioral attributes play a major role in the proliferation of these diseases. Lockdown and social distancing have affected social behavioral aspects of human life and somehow impact on the spread of vector borne diseases. This article sheds light into the relationship between COVID-19 lockdown and global dengue burden with special focus on India. It also focuses on the interconnection of the COVID-19 pandemic (waves 1 and 2) and the alteration of human behavioral patterns in dengue cases. METHODS: We performed a systematic search using various resources from different platforms and websites, such as Medline; Pubmed; PAHO; WHO; CDC; ECDC; Epidemiology Unit Ministry of Health (Sri Lanka Government); NASA; NVBDCP from 2015 until 2021. We have included many factors, such as different geographical conditions (tropical climate, semitropic and arid conditions); GDP rate (developed nations, developing nations, and underdeveloped nations). We also categorized our data in order to conform to COVID-19 duration from 2019 to 2021. Data was extracted for the complete duration of 10 years (2012 to 2021) from various countries with different geographical region (arid region, semitropic/semiarid region and tropical region). RESULTS: There was a noticeable reduction in dengue cases in underdeveloped (70-85%), developing (50-90%), and developed nations (75%) in the years 2019 and 2021. The dengue cases drastically reduced by 55-65% with the advent of COVID-19 s wave in the year 2021 across the globe. CONCLUSIONS: At present, we can conclude that COVID-19 and dengue show an inverse relationship. These preliminary, data-based observations should guide clinical practice until more data are made public and basis for further medical research.

ABSTRACT

INTRODUCTION: Quality of life (QoL) in adolescent patients suffering from type 2 diabetes mellitus (T2DM) has not been thoroughly explored in Saudi Arabia. Herein, we aimed to measure the health-related quality of life (HRQoL) in adolescent patients suffering from T2DM and explore the correlation between adolescents' self- and parent-reporting of QoL scores, and glycaemic control (HbA1c). MATERIAL AND METHODS: A retrospective multi-centre cohort study was conducted at 4 hospitals in Riyadh, Saudi Arabia. The Paediatric Quality of Life Inventory (PedsQLTM) Diabetes Module 3.0 was completed by children and their parents in a confidential and anonyms manner through a phone interview. RESULTS: We recruited 49 paediatric patients for this study (mean age: 18.45 years; male: 55%). Both children and parents reported low cumulative mean scores for PedsQL™ (58.65 and 57.38, respectively) as compared to previous international studies. The lowest obtained score was noted for the diabetes symptoms domain (53.4). Comparing the magnitude of discrepancy between the adolescents' and parents' subscale scores revealed a non-significant difference, except for the 'worry' subscale, in which parents reported significantly higher mean scores (76.73 vs. 60.54, p = 0.02). Comparison of mean scores reported by adolescents who met the target HbA1c goal (<7%) and their counterparts revealed a non-significant difference, suggesting an irrelevant impact of this parameter on their perspectives or experiences. CONCLUSIONS: The study findings emphasized the need to initiate further intensive awareness programs concerning this disease and its clinical implications in T2DM children to improve treatment adherence and symptoms, and consequently improve the perception of the patient and the family for HRQoL.

ABSTRACT

BACKGROUND: Anticoagulation management is a complex process that is managed through careful monitoring, and patient satisfaction has a significant impact. Given the lack of a valid and reliable tool in Arabic to examine patient satisfaction, the present study aimed to translate and examine some of the psychometric properties of the Anti-Clot Treatment Scale (ACTS) among Saudi patients. MATERIALS AND METHODS: This was a cross-sectional, methodological study conducted among patients receiving warfarin. The questionnaire was subjected to translation by using a multistep method. The final Arabic translated version of the ACTS underwent face and content validity assessments by independent experts to ensure its conceptual equivalence to the original English version. Subsequently, pilot testing of convergent, discriminant, and criterion validities were examined. RESULTS: Overall, 136 patients participated in the study. All patients were asked to complete the generic Treatment Satisfaction Questionnaire for Medication (TSQM) alongside the ACTS tool. Convergent validity analyses revealed statistically significant positive correlations (p < 0.01) between the ACTS subscales and the four TSQM subdomains, as reflected by the Spearman correlation coefficient (r). Interestingly, the strongest correlations were observed between ACTS Burdens and the TSQM convenience domain (r = 0.61) and between ACTS Benefits and the TSQM effectiveness satisfaction score (r = 0.58). Similarly, discriminant validity was evidenced by moderate to high significant loading of all 12 items on each of their corresponding ACTS subscales. CONCLUSION: These findings of adequate validity support the use of the ACTS in Saudi patients receiving anticoagulant medications to measure their specific satisfaction levels with this type of therapy. However, future research addressing the clinical impact of ACTS scores in the Saudi population is needed.

ABSTRACT

BACKGROUND: Long-term anticoagulation therapy, particularly with warfarin, is usually associated with poor adherence and low patient satisfaction. However, previous studies have highlighted the possibility that individual perceptions of warfarin differ according to cultural practices. This study validated the psychometric properties of the translated Arabic version of the Anti-Clot Treatment Scale (ACTS) for patients on warfarin therapy in Saudi Arabia. METHODS: A cross-sectional multicenter study was conducted at the three main medical centers in Riyadh. Stratified sampling was employed to recruit Arabic-speaking patients who had been taking warfarin for a minimum of 3 months for any indication. The patients completed the specific ACTS along with the generic Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) at two clinic visits. The psychometric performance of the ACTS was evaluated using well-established criteria: feasibility, reliability, and validity. RESULTS: One hundred thirty-six patients participated in the study (mean age: 50.68 ± 14.6 years; range: 19-97). Overall, the patients reported moderate Burdens and Benefits scores (44 ± 9.9 and 11.92 ± 2.4, respectively) compared to the reference range for each subscale (12-60 and 3-15, respectively); however, they reported lower Burdens scores than other populations. Consistent with the original ACTS validation study, the criteria for acceptability (data targeting, floor/ceiling effects, and skewness) were satisfied; in fact, the Arabic version exhibited better item- and scale-level distributions of data than versions in other languages. The ACTS subscales also demonstrated satisfactory test-retest reliability with significant intraclass correlation coefficients ((ICC ≥ 0.5); p < 0.001) and good internal consistency (all Cronbach's alpha values exceeded 0.7). Exploratory factor analysis supported the 2-factor loading model. Interestingly, the Arabic version exhibited greater convergent validity with the TSQM subdomains (r = 0.61). CONCLUSIONS: This study provides convincing evidence that the Arabic versions of both the ACTS Burdens and ACTS Benefits scales are equivalent to other versions in terms of psychometric performance, as measured using reliability and validity criteria. These properties support the great potential of the Arabic ACTS to accurately reflect patient satisfaction, identify aspects of treatment that need improvement in clinical practice, and compare treatment satisfaction across different anticoagulant therapies or cultures in research.

ABSTRACT

CONTEXT: Internationally, various warfarin education strategies have been described in the medical literature and delivered by a variety of health-care providers. However, none of these were tested in a Saudi setting. AIM: The aim of this study was to assess the impact of pharmacist interventions via an educational video on improving patient knowledge of and satisfaction with warfarin therapy and the international normalized ratio (INR). SETTING AND DESIGN: This study adopted a prospective pre- and posttest design and enrolled 91 patients from an anticoagulant clinic at King Khaled University Hospital in Riyadh, Saudi Arabia, between September 2017 and February 2018. MATERIALS AND METHODS: All patients completed the Anticoagulation Knowledge Assessment (AKA) and Anti-Clot Treatment Satisfaction (ACTS) scales. Subsequently, the patients watched a 10-min educational video containing basic information regarding warfarin and were given relevant informative booklets. The patients were reassessed after a mean follow-up period of approximately 52 days. RESULTS: In total, 85 patients completed the study. The impact of the intervention on patient knowledge was highly significant (mean difference = 17.7%, 95% confidence interval (CI) = 21.75-13.58, P < 0.000). In addition, the patients showed significant increases in their ACTS benefits subscale scores (mean difference = 0.73, 95% CI = 1.22-0.24, P = 0.004). Despite being long-term warfarin users, the patients' INRs had a greater tendency to be within the target range after the intervention (56.63% ± 35% vs. 64.72% ± 35% of the time; mean difference, 8.1 percentage points; effect size = 0.23). However, there was no significant effect on patients' perceptions of the warfarin burden. CONCLUSION: This study provided evidence that a pharmacist-led audiovisual intervention via an educational video coupled with an informational booklet effectively improved patients' knowledge retention and satisfaction with warfarin therapy benefits. Longer studies are needed to determine the impact of this intervention on patients' perceptions of warfarin burdens and their INRs.

ABSTRACT

OBJECTIVES: To validate the psychometric properties of the translated Arabic version of the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) for patients on warfarin therapy in Saudi anticoagulation clinics (ACCs). METHODS: A cross-sectional survey was conducted at the Security Forces Hospital ACC in Riyadh, Saudi Arabia. It involved administering questionnaires related to patients' satisfaction and assessing adherence through interviews. The quality of the international normalized ratio control was assessed using the Rosendaal method. A psychometric evaluation of TSQM 1.4 was carried out, addressing internal consistency and known-groups and convergent validity. RESULTS: A total of 101 patients completed the questionnaire with an 80% response rate. The independent Cronbach α values for the effectiveness, side effects, and global satisfaction domains were consistently higher than 0.75, demonstrating good internal consistency and suitability of these domains for application in the current patients' setting. When these domains were used together in a multivariable logistic regression model of adherence, the only domain that remained significant was TSQM effectiveness (P = 0.017). Interestingly, a higher likelihood of moderate to optimal international normalized ratio control was significantly and independently associated with increased satisfaction scores in the effectiveness and convenience domains, but not in the side effects and global satisfaction domains. CONCLUSIONS: This study provides evidence in favor of the reliability and validity of the Arabic version of TSQM 1.4 as a useful measure of satisfaction with anticoagulant therapy in patients visiting ACCs. The TSQM subscales in this patient setting seem to detect a clinically meaningful change over time, enhancing the potential of their use in routine practice.

ABSTRACT

Background Although it can result in serious complications due to its narrow therapeutic index, warfarin is widely used in the treatment and prevention of thromboembolic disorders. However, patients' adherence and knowledge are determinants of therapeutic success. Objective We sought to validate instruments to provide a reliable means of identifying gaps in patient understanding and nonadherence to inform targeted pharmacists' interventions to improve these measures. Methods A cross-sectional survey was conducted. Patients' knowledge about warfarin was rated using an Arabic-language tool. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). The international normalized ratio (INR) control was quantified by the Rosendaal Method. Setting At the Security Forces hospital anticoagulant clinic (ACC), Riyadh. Main outcome measure Validity of a Knowledge and adherence tool. Results Totally, 101 patients completed the questionnaires. Interestingly, the knowledge tool demonstrated good internal consistency (total Cronbach's alpha = 0.75) and significant concurrent validity with adherence levels. Fifty-two patients were classified as having unsatisfactory knowledge. Deficiency in knowledge was most obvious with respect to the consequences of missing a dose and when to seek immediate medical attention. The MMAS-8 had moderate reliability (Cronbach's alpha = 0.65); however, its concurrent validity with good INR control was not demonstrated. Conclusions This study revealed high prevalence of nonadherence and poor knowledge in the population visiting the ACC. Given that available knowledge and adherence tools seemed to have little validity in predicting clinical outcomes, structured tools should be designed, considering progression in clinical outcomes with future pharmacists' interventions.

ABSTRACT

BACKGROUND: There is an elevated rate of hereditary hemoglobinopathies in Arab populations. To address this, the Saudi government has implemented a mandatory premarital screening (PMS) program. Nevertheless, reports have shown that 48% of genetically incompatible partners have decided to marry. To address this, more information is needed on people's beliefs on these issues. AIM: To investigate the knowledge, attitudes, and practices of Taif University students towards the national PMS program. MATERIALS AND METHODS: Using a questionnaire, a cross-sectional study was conducted during April-May 2016 on a random sample of university students in Taif City. It was administered electronically and primarily distributed through social media. RESULTS: Most participants (97.4%) were aware that genes may transmit hereditary diseases and had heard about the PMS program. Most participants who partook in the PMS justified it based on preventing disease transmission to their offspring and ensuring their partner's health. A fair number (82.9%) were willing to change their decision to marry in the case of receiving incompatible results. Moreover, the majority of the participants (91.8%) demanded the implementation of a law that prohibits incompatible marriages. CONCLUSION: Most Taif University students have a generally positive attitude and good intended practices toward PMS. However, targeted educational programs about the importance of PMS are strongly recommended to eliminate all factors that may affect the success of the PMS program.

ABSTRACT

The aim of this study was to evaluate whether genetic polymorphisms in CYP3A5 and ABCB1 are responsible for the interindividual variability observed in quetiapine pharmacokinetics. Pharmacokinetic data from a randomized crossover study evaluating 2 quetiapine 25 mg immediate-release tablets after single oral dose were used to develop a population pharmacokinetic model. The single nucleotide polymorphisms (SNPs) evaluated for the genotype effects of quetiapine pharmacokinetics were CYP3A5 A6986G and ABCB1 C3435T, along with other demographic variables and formulations. A one-compartment distribution model with linear elimination plus four transit compartments for the delayed absorption adequately described quetiapine disposition. CYP3A5 *1/*1 individuals (n = 3) had 29% increased clearance compared to *1/*3 and *3/*3 individuals. The impact of an increased clearance was evaluated by simulations. By computing the probability of target attainment (PTA) of steady-state therapeutic goal at 1-hour and 12-hour time points after 50-400 mg twice-daily regimens, the results indicated that CYP3A5 genotype has minimal impact on the PTA of the 1-hour concentrations but a significant impact on the 12-hour concentrations. The interpretation based on the simulations does not call for a genotype-based dosing scheme and is consistent with consensus guidelines for quetiapine that therapeutic drug monitoring is considered useful.

ABSTRACT

Recent pharmacogenetic studies involving various transplant recipients in diverse ethnic populations revealed contradictory findings regarding the impact of CYP3A5 and multidrug resistance-1 (MDR1) single nucleotide polymorphisms (SNPs) on the pharmacodynamics of tacrolmius (TAC). The aim of the current study was to evaluate the impact of these SNPs on the time required to attain target TAC levels and subsequent pharmacodynamic outcomes in pediatric kidney transplant patients. Thirty-eight patients were genotyped for CYP3A5FNx011 and FNx013, and MDR1 C3435T. Notably, none of the patients expressing CYP3A5 FNx011FNx011 or FNx011FNx013 achieved the target concentration of 10-20 ng/mL within the first 2 weeks or even the first month after transplant. However, 34.4% of CYP3A5 FNx013FNx013 achieved and maintained the target goal within the first and second weeks (P <0.05). In contrast, C3435T polymorphism had no significant influence on the proportion of patients achieving target TAC levels. An examination of the impact of genotype combinations on clinical outcomes revealed an increased incidence of acute, chronic rejection and graft loss in patients carrying heterozygous MDR1 C3435T alleles (CT); this indicates the possibility of an additive effect of this SNP on its concurrent combination with a FNx013FNx013 SNP. In conclusion, our study revealed trends toward unwanted outcomes in CYP3A5 non-expressers with an unexplained correlation with MDR1 C3435T polymorphisms. Recommending routine pharmacogenetic testing of the individual SNPs in renal transplant patients is not yet feasible as the relationship of cost-effectiveness to ultimate impact on graft or patient survival must be justified by further prospective clinical trials.
