A survey of drive-thru pharmacy services: Evaluating the acceptance and perspectives of community pharmacists in Saudi Arabia.

Background: The practice of dispensing drugs in primary healthcare centers has shifted to community pharmacies in Saudi Arabia. These changes increase demand and mandate improving their services; one such is establishing pharmacy drive-thru services. To explore the effects of drive-thru services on the pharmacy profession, this study aimed to measure community pharmacists' acceptance, perception, and satisfaction regarding drive-thru services. Methods: This cross-sectional study design was conducted in Saudi Arabia between January 2023 and May 2023-comparing the perception, acceptance, and satisfaction of pharmacists who work in a community pharmacy that provides a drive-thru service versus no drive-thru service. Community pharmacists were invited to complete an online questionnaire consisting of four sections developed from previous studies with some modifications. Descriptive statistical analysis and an independent t-test were utilized to test the difference between the two groups (providing drive-thru service vs. non) in their responses. Results: This study included 380 community pharmacists, of whom 33 % provided drive-thru services and 67 % did not. Pharmacists' perceptions of drive-thru services differed significantly. Those with drive-thru services perceived lower convenience for delivering drug information and patient counseling, and they were concerned about the potential impact on their health effects (M = 3.15, SD = 1.34) compared to those without (M = 3.58, SD = 1.10), t (3 7 8) = -3.32, p < 0.01). However, they recognized the convenience of serving sick patients, the elderly, disabled individuals, and mothers with children in cars (M = 3.71, SD = 1.17), which was higher than those without (M = 4.04, SD = 1.21), t (3 7 8) = -2.70, p < 0.01). Regarding the current pharmacy layout suitability, pharmacists with drive-thru services found it more suitable (M = 3.13, SD = 1.14) than those without (M = 2.49, SD = 1.14), t (3 7 8) = 5.1, p < 0.01). However, the two groups had no significant difference in overall satisfaction. Conclusion: Pharmacists working in pharmacies offering drive-thru services recognized certain benefits but also expressed concerns about health effects and decreased convenience for counseling. These findings provide valuable insights for policymakers and pharmacy management, highlighting the nuanced views of pharmacists in adopting drive-thru services.

A Surgical Framework for the Management of Incomplete Axillary Nerve Injuries.

BACKGROUND: Axillary nerve injury is the most common nerve injury affecting shoulder function. Nerve repair, grafting, and/or end-to-end nerve transfers are used to reconstruct complete neurotmetic axillary nerve injuries. While many incomplete axillary nerve injuries self-resolve, axonotmetic injuries are unpredictable, and incomplete recovery occurs. Similarly, recovery may be further inhibited by superimposed compression neuropathy at the quadrangular space. The current framework for managing incomplete axillary injuries typically does not include surgery. METHODS: This study is a retrospective analysis of 23 consecutive patients with incomplete axillary nerve palsy who underwent quadrangular space decompression with additional selective medial triceps to axillary end-to-side nerve transfers in 7 patients between 2015 and 2019. Primary outcome variables included the proportion of patients with shoulder abduction M3 or greater as measured on the Medical Research Council (MRC) scale, and shoulder pain measured on a Visual Analogue Scale (VAS). Secondary outcome variables included pre- and postoperative Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH) scores. RESULTS: A total of 23 patients met the inclusion criteria and underwent nerve surgery a mean 10.7 months after injury. Nineteen (83%) patients achieved MRC grade 3 shoulder abduction or greater after intervention, compared with only 4 (17%) patients preoperatively (p = 0.001). There was a significant decrease in VAS shoulder pain scores of 4.2 ± 2.5 preoperatively to 1.9 ± 2.4 postoperatively (p < 0.001). The DASH scores also decreased significantly from 48.8 ± 19.0 preoperatively to 30.7 ± 20.4 postoperatively (p < 0.001). Total follow-up was 17.3 ± 4.3 months. CONCLUSION: A surgical framework is presented for the appropriate diagnosis and surgical management of incomplete axillary nerve injury. Quadrangular space decompression with or without selective medial triceps to axillary end-to-side nerve transfers is associated with improvement in shoulder abduction strength, pain, and DASH scores in patients with incomplete axillary nerve palsy.

Prevalence of polypharmacy in heart failure patients: A retrospective cross-sectional study in a tertiary hospital in Saudi Arabia.

Background: Cardiovascular disease is the leading cause of death and disability worldwide. It is a general term used to describe a group of disorders that affect the heart or blood vessels. This study aimed to evaluate the prevalence and predictors of polypharmacy in patients with heart failure. Methods: We conducted a cross-sectional study in a tertiary hospital in Saudi Arabia. Data was extracted from an electronic database between January 2019, and December 2022. The study included all adult patients with heart failure who visited outpatient clinics; individuals with cancer were excluded. The outcome variable in our study was "polypharmacy" which was defined as the use of eight or more medications. Descriptive analysis was performed using frequencies and percentages for categorical variables. In addition, Multivariate logistic regression was used to assess the covariates associated with polypharmacy. Results: A total of 331 patients with heart failure were included in this study. The prevalence of polypharmacy among our HF population was 39.88 %. Most participants were male (60.73 %), and 60 years or older (68 %). The most frequently used medications were beta-blockers (67.98 %) and diuretics (58.31 %), whereas the least frequently used medications were hydralazine and histamine H2 blockers (5.74, and 3.02 %, respectively). Polypharmacy was likely to be a non-significantly higher in individuals aged between 60 and 69 years (adjusted odds ratio (AOR) = 1.52; 95 % confidence interval (CI) 0.78-2.98) and suffering from hypertension (AOR = 1.48; 95 % CI 0.83-2.64). However, patients with heart failure and diabetes mellitus had a significant six-fold higher of polypharmacy than those without diabetes mellitus (AOR = 6.55; 95 % CI 3.71-11.56). Conclusion: Patients with heart failure often use multiple medications. Patients with heart failure together with diabetes have a higher risk of polypharmacy. Therefore, healthcare professionals should manage polypharmacy to improve the outcomes in patients with heart failure.

Pharmacy practice research in Saudi Arabia; A bibliometrics analysis from (2000 to 2021).

Background: Pharmacy is a growing profession in the Kingdom of Saudi Arabia which has experienced tremendous changes in the past 20 years. Pharmacy practice or clinical pharmacy have an attention ever since the emerging of PharmD programs throughout the Saudi universities. As a result, the number of affiliated faculty in the pharmacy practice departments has increased dramatically in the past 20 years and thus significant changes in research output were observed. Objectives: The main objective is to conduct a bibliometric analysis and evaluate the research output of pharmacy practice faculty in Saudi Universities from 2000 to 2021. Methods: A systematic search was conducted using Scopus database to explore the research output from pharmacy practice affiliated faculty from 2000 to 2021. The following search terms AFFILORG ("Pharmacy Practice Department" OR "Department of Pharmacy practice" OR "Clinical Pharmacy Department" OR "Department of Clinical Pharmacy" OR "Department of Pharmacy Services") AND AFFILCOUNTRY ("Saudi Arabia" OR "KSA" OR "Kingdom of Saudi Arabia") were used. Only original research papers were retrieved and analyzed using MS Excel (v16.0), MS Access (v16.0), Bibexcel (v2017), VOS viewer, and Biblioshiny. Results: In the past two decades, most publications with pharmacy practice departments affiliation were pharmacy practice research irrelevant (only 1075 out of 2809). King Saud University and King Abdulaziz University were the top performing institutes, and median of 5-year impact factor for journals was more than 3 for most of the top 10 institutes. 19% of the total retrieved articles were review publications were the rest majorly classified as cross-sectional studies. Conclusion: The research contribution of pharmacy practice departments in Saudi Arabia has been improving. Key recommendations are to promote more applied and interventional research, increase publications in top journals, and enhance national collaborations.

Incidence and risk factors of adverse drug reactions in patients with coronavirus disease 2019: A pharmacovigilance experience utilizing an ADR trigger tool.

BACKGROUND: Since the World Health Organization declared coronavirus disease (COVID-19) as a pandemic, most countries started treating their patients with various therapies. However, the data regarding their safety and effectiveness is still lacking. OBJECTIVES: We aimed to evaluate the adverse drug reactions (ADRs) incidence and their predisposing factors among COVID-19 patients. METHODS: A retrospective observational study that was conducted at a tertiary academic hospital from March - June 2020. Patients were included if they were ≥ 18 years old, inpatient, had a reverse transcriptase-polymerase chain reaction (PCR) positive for COVID-19, and were treated with; (lopinavir-ritonavir, hydroxychloroquine, chloroquine, favipiravir, ribavirin, or interferon-ß) either as monotherapy or combination therapy for three days or longer. The data of eligible patients were retrieved from the electronic medical records. A standardized data collection form was designed to collect patient demographics, COVID-19 severity based on the Saudi Ministry of Health management protocols, antiviral therapies, duration of therapy, and length of stay (LOS). The ADRs were identified via conducting a comprehensive review using predefined triggers and were evaluated using Naranjo Score. RESULTS: A total of 155 patients were included of which 123 (79.4%) were males. In our sample, the incidence proportion of ADRs per patient was 72.3%. A total of 287 ADRs were identified most of them were hepatic (n = 101, 35.2%), gastrointestinal (n = 59, 20.6%), hematological (n = 47, 16%), and endocrine (n = 45, 15%). Hydroxychloroquine was the most common drug associated with ADRs (n = 155). The length of stay (10 - 20 days) was the only statistically significant with the ADR incidence (p-value = 0.008; 95 %CI 1.216:3.568). CONCLUSIONS: The ADRs are prevalent among COVID-19 patients, which assure the importance of implementing active hospital-based pharmacovigilance systems.

Lateralization value of peri-ictal headache in drug-resistant focal epilepsy.

OBJECTIVE: To examine the lateralizing value of unilateral peri-ictal and interictal headaches in patients with drug-resistant focal epilepsy (DRFE). METHODS: Four-hundred consecutive patients undergoing presurgical evaluation for DRFE were interviewed. Patients with headache were broadly divided into two groups: peri-ictal and interictal headache. The lateralizing value of unilateral headache was compared in each group between three diagnoses: temporal lobe epilepsy (TLE), extratemporal lobe epilepsy (ETLE), and temporal-plus epilepsy (TEMP+ epilepsy). RESULTS: Out of 400 patients, 169 (42.25%) had headaches. Peri-ictal headaches were experienced in 106 patients (26.5%) and interictal headaches were experienced in 63 (15.75%). In the peri-ictal group, unilateral headaches were present in 48 out of 60 patients (80%) with TLE; they were ipsilateral to the seizure focus in 45 out of 48 patients (93.75%). Unilateral headaches in patients with ETLE were present in 20 out of 31 patients (64.5%) and were ipsilateral to the seizure focus in 14 out of 20 patients (70%). In patients with TEMP + epilepsy, unilateral peri-ictal headaches were present in 9 out of 15 patients (60%); they were ipsilateral to the seizure focus in all 9 patients (100%). In the interictal headache group, unilateral headaches were ipsilateral the seizure focus in 9 out of 10 patients (90%) with TLE and 5 out of 6 patients (83.3%) with ETLE. None of the TEMP + epilepsy patients had a unilateral interictal headache. CONCLUSION: Headache is a frequently encountered symptom in patients with DRFE. When occurring in a unilateral fashion, it has a high lateralizing value in temporal and extratemporal lobe epilepsies. This has been demonstrated to be true for both peri-ictal and interictal headaches. In the vast majority of patients with DRFE, unilateral headache occurs ipsilateral to the seizure focus.

Changes in student pharmacists' confidence in attaining geriatrics competencies and attitudes toward older adults across the Doctor of Pharmacy curriculum.

To determine if student pharmacists' confidence in their knowledge and skills, and their attitudes toward older adults improved throughout pharmacy school with an integrated geriatrics didactic curriculum (years 1-3) and a final year of clinical training including a required advanced pharmacy practice experience (APPE) in geriatrics (year 4). A two-part voluntary anonymous survey was administered at three different time points to two large cohorts of student pharmacists. The first part of the survey assessed students' confidence in attaining geriatrics competencies. The second part of the survey used the UCLA Geriatrics Attitudes Scale to assess students' attitudes. Of the 286 students who were emailed the survey, 236 student pharmacists completed it at the first assessment. Student pharmacists showed an increase in confidence in achieving geriatrics competencies from their first year to their third year, and further increase after their clinical training. Most students also held a generally positive attitude toward older adults from P1 to P4 year. Integration of geriatrics throughout the didactic and experiential curriculum made an impact on student pharmacists' confidence in their competency toward caring for older adults, while maintaining a positive attitude toward older adults throughout pharmacy school.

Multifaceted C-X-C Chemokine Receptor 4 (CXCR4) Inhibition Interferes with Anti-Vascular Endothelial Growth Factor Therapy-Induced Glioma Dissemination.

Resistance to antiangiogenic therapy in glioblastoma (GBM) patients may involve hypoxia-induced expression of C-X-C motif chemokine receptor 4 (CXCR4) on invading tumor cells, macrophage/microglial cells (MGCs), and glioma stem cells (GSCs). We determined whether antagonizing CXCR4 with POL5551 disrupts anti-vascular endothelial growth factor (VEGF) therapy-induced glioma growth and dissemination. Mice bearing orthotopic CT-2A or GL261 gliomas received POL5551 and/or anti-VEGF antibody B20-4.1.1. Brain tissue was analyzed for tumor volume, invasiveness, hypoxia, vascular density, proliferation, apoptosis, GSCs, and MGCs. Glioma cells were evaluated for CXCR4 expression and polymorphism and POL5551's effects on CXCR4 ligand binding, cell viability, and migration. No CXCR4 mutations were identified. POL5551 inhibited CXCR4 binding to its ligand, stromal cell-derived factor-1α, and reduced hypoxia- and stromal cell-derived factor-1α-mediated migration dose-dependently but minimally affected cell viability. In vivo, B20-4.1.1 increased hypoxic foci and invasiveness, as seen in GBM patients receiving anti-VEGF therapy. Combination of POL5551 and B20-4.1.1 reduced both glioma invasiveness by 16% to 39% and vascular density compared to B20-4.1.1 alone in both glioma models. Reduced populations of GSCs and MGCs were also seen in CT-2A tumors. POL5551 concentrations, evaluated by mass spectrometry, were higher in tumors than in neighboring brain tissues, likely accounting for the results. Inhibition of CXCR4-regulated tumoral, stem cell, and immune mechanisms by adjunctive CXCR4 antagonists may help overcome antiangiogenic therapy resistance, benefiting GBM patients.

Combined Anterolateral Thigh and Tensor Fasciae Latae Flaps: An Option for Reconstruction of Large Head and Neck Defects.

PURPOSE: The advent of microvascular free tissue transfer has provided the reconstructive surgeon with an enormous array of treatment options for reconstruction of large head and neck defects. However, when indicated by defect size, the need for more than 1 flap not only increases surgical complexity but also patient morbidity. The combination of the anterolateral thigh (ALT) flap and the tensor fascia latae (TFL) flap can be used to reconstruct such complex head and neck defects, thereby minimizing any additional morbidity that would be imposed by an additional flap harvest site. The present study reports on the use of the combined ALT-TFL flap to reconstruct large and complex head and neck defects. MATERIALS AND METHODS: A retrospective chart review was conducted of all microvascular head and neck reconstructions performed by the Maxillofacial Tumor and Reconstructive Surgery Service at the University of Miami/Jackson Health System (Miami, FL) from 2013 through 2016. Inclusion criteria for the study were head and neck defects at least 20 m × 10 cm and reconstruction with soft tissue flaps using perforating vasculature to the TFL and ALT vascular territories. Other study data included disease history, location of defect, flap size, recipient vessels, harvest time, ischemia time, surgical complications, and overall flap survival. RESULTS: Seven patients met the inclusion criteria. Five patients were treated for the diagnosis of stage III osteoradionecrosis and 2 patients underwent reconstruction in conjunction with ablative surgery for head and neck carcinoma. All 7 patients underwent successful head and neck reconstructions using the ALT-TFL flap. There was no partial or total flap failure. One patient had a wound healing complication at the donor site that did not require surgical intervention. CONCLUSION: Reconstruction of a large head and neck soft tissue defect with a combined ALT-TFL flap is a reliable method with minimal donor site morbidity and no major postoperative complications. This combined flap should be considered when the defect size extends beyond the bounds allowed by the ALT flap alone.

Assessing Public Awareness, Utilization and Satisfaction with Community Pharmacy Services.

Background: The Saudi Community pharmacy sector has been changing towards patient-centred care rather than depending solely on dispensing medications. Accordingly, pharmacies can now provide many services that they previously could not offer. The aims of this study were to identify all pharmacy services provided in a community setting and to assess public awareness and utilization of and satisfaction with these services. Methods: This was a cross-sectional study in which the authors first purposively visited community pharmacies to identify the services offered. Pharmacists were asked about pharmacy services currently provided to community. Fieldnotes were used to document pharmacists' responses. After identifying pharmacy services, a questionnaire was desgined and reviewed by experts in the field, piloted and approved by the Ethics Committee at King Faisal University, then disseminated via Google Forms. The satisfaction level with pharmacy services was assessed using a five-point Likert scale. Data were collected from 24 January 2023 to 2 March 2023. Results: Eighteen community pharmacies offering 17 different services were visited across Alahsa Governorate. The number of participants who completed the questionnaire was 350. Of those (232 [66.3%]) were female, and the majority of the sample (80.5%) were younger than 40 years old. The majority of the participants were unaware of pharmacy services. Out of 17 services, six received a score of 50% or higher regarding participant awareness. The most utilized services were the medication dispensing service "Wasfaty" (250 [71.4%]), medication counselling provided by pharmacists (232 [66.3%]) and minor ailment service (231 [66%]). The overall satisfaction score for pharmacy services was 87.2%. Conclusion: The majority of the participants were unaware of the full range of available pharmacy services. There is a potential for community pharmacists to fill the capacity gap in the healthcare system since, overall, the participants rated the pharmacies' clinical services as satisfactory. Commissioners of pharmacy services may consider extending the scope of community pharmacies to include services that best utilize the expertise of clinical pharmacists.

Posterior reversible encephalopathy syndrome post stem cell transplantation in sickle cell disease: case series and literature review.

Introduction: Posterior reversible encephalopathy syndrome (PRES) is a serious neurological syndrome that may develop following immunosuppressive therapy for stem cell transplantation (SCT). We report 8 patients with sickle cell disease (SCD) who developed PRES, which is likely to be related to immunosuppression. Methods: This is retrospective cohort analysis of the SCD registry at the King Faisal Specialist Hospital and Research Center (KFSHRC) in Riyadh, Saudi Arabia. Inclusion criteria included all adults SCD patients who underwent SCT from 2011 until 2022. We explored all cases of PRES in patients with SCT. PRES was diagnosed with MRI imaging showing reversible vasogenic cerebral edema associated with neurological symptoms including severe headache, seizures, encephalopathy, delirium, and visual disturbances. Results: During ten years follow-up (2011-2022) we found 8 patients with PRES (age range between 14 to 37 years at diagnosis) PRES occurred 8 to 124 days following SCT in 7 cases and one patient developed PRES 8 months prior to SCT. All patients were on immunosuppressive medications, including tacrolimus, cyclosporine, sirolimus and or mycophenolate mofetil. Headache, seizures, visual hallucinations, confusion, and drowsiness were the most common presenting symptoms. MRI showed abnormalities in the occipital, parietal and frontal lobes in most cases. Recovery was complete in all patients and no recurrences were noted. Two patients had graft versus host disease (GVHD). We compared risk factors for PRES among the 8 cases and 136 SCT in SCD patients who did not develop PRES. There was a significant association between PRES and imaging abnormalities, including previous bi-hemispheric infarctions (p = 0.001), and cerebral microbleeds (CBMs). PRES was strongly associated with presence (p = 0.006), size (p = 0.016) and number (p = 0.005) of CMBs. Conclusion: PRES can develop days to weeks following SCT in patients with SCD, and is associated with immunosuppressive therapy, previous bi-hemispheric infarctions and CMB. Prompt recognition and intervention leads to good recovery.

The Association between Self-Care Activities and Depression in Adult Patients with Type 2 Diabetes in Saudi Arabia: A Cross-Sectional Web-Based Survey Study.

This study examined the level of adherence to self-care behaviors among individuals with type 2 diabetes in Saudi Arabia and its connection with depression and demographic factors. A cross-sectional survey was conducted among diabetes patients using the Patient Health Questionnaire (PHQ-9) to measure depression and the Summary of Diabetes Self-Care Activities (SDSCA) to evaluate diabetes self-care activities. Among the 252 participants who completed the survey, 43.2% were older than 55 and 59% were men. The ordinal regression model showed an association between the PHQ-9 and SDSCA scores with an OR of 0.83 (95% CI: 0.71 to 0.96, p = 0.013). The PHQ-9 score was significantly associated with blood sugar monitoring (OR: 0.90 [95% CI: 0.82 to 0.99, p = 0.003]), exercise (OR: 0.88 [95% CI: 0.79 to 0.98, p = 0.002]), and diet (OR: 0.94 [95% CI: 0.85 to 1.03, p = 0.045]). Of all the diabetes-related factors, only a history of hospitalization and receiving diabetes education were found to be associated with improved self-care behaviors. In conclusion, a negative association was found between PHQ-9 scores and the SDSCA mean score and most daily diabetic self-care behavior components.

The current view of potentially inappropriate medications (PIMs) among older adults in Saudi Arabia: a systematic review.

Introduction: Potentially inappropriate medications PIMs are common among elderly population and becoming a global health issue. It has been associated with negative health consequences like preventable adverse drug reactions, hospitalization and mortality. Objectives: To investigate the most commonly potentially inappropriate medications in older adults in Saudi Arabia. Additionally, we aim to gain insights into the typical healthcare settings where healthcare providers offer services related to PIMs. Methods: This is a systematic review design using Preferred Reporting Items Systematic Reviews and Meta-Analysis (PRISMA) statement. PubMed and Google Scholar were used to search for the relevant studies using the following keywords (older adults, elderly, potentially inappropriate medications, inappropriate medications, PMIs, Saudi Arabia, Kingdom of Saudi Arabia) with no restrictions to the date of publications nor the study language. Results: Only 8 studies have met our inclusion and exclusion criteria, which was most of them were cross-sectional study design (n = 6.75%) and all of them have been conducted in hospital-based settings. In addition, the prevalence of PIMs ranged from 19% to 80% depends on the site and administration of the study. We have found that proton pump inhibitors, non-steroidal anti-inflammatory drugs, aspirin, diuretics, gastrointestinal medications, and antidepressants were the most common reported PIMs in the included studies. Conclusion: The prevalence of PIMs among the elderly in Saudi Arabia is notably high ranged from 19% to 80%, underscoring the need for additional research to assess the existing practices within this vulnerable demographic across various healthcare settings.

Effect of type of disease-modifying antirheumatic drugs on depression and anxiety of patients with rheumatoid arthritis in Saudi Arabia: a cross-sectional study.

Background: Rheumatoid arthritis (RA) can cause depression and anxiety. This study evaluated the factors associated with depression and anxiety in patients with RA and examined the effect of conventional and biologic disease-modifying antirheumatic drugs (DMARDs). Methods: This cross-sectional study was conducted in a regional hospital in Riyadh between March and November 2022 and included 213 patients with RA. Depression and anxiety were measured using the Hospital Anxiety and Depression Scale (HADS) and data about patients' DMARDs use was obtained from the hospital's medical records. Results: Based on the HADS scores, 35 (16.4%) and 49 (23%) patients with RA had depression and anxiety, respectively. There was a significant association between the level of depression and anxiety and the use of leflunomide and tocilizumab among patients with RA (p = 0.006 and p = 0.009, respectively). Patients with RA who took leflunomide had significantly higher scores for anxiety (ß = 0.158, value of p = 0.037) when compared to patients who did not take leflunomide. Patients with RA who took etanercept showed a significantly lower depression score even after adjusting for confounders, including sociodemographic, clinical, and lifestyle factors (ß = -0.189, p = 0.043). Conclusion: The present study highlighted the prevalence of psychiatric disorders among patients with RA and the level of depression and anxiety may differ between patients with RA depending on the type of DMARDs used. We recommend patients with RA be screened regularly for depression and anxiety to avoid further extra-articular systemic complications associated with RA.

The Level of Burden among Caregivers of Patients with Alzheimer's Disease in Saudi Arabia.

BACKGROUND: Caregiver burden is a serious global issue associated with the growing number of older adult patients with Alzheimer's disease (AD). AD patients become more dependent on their caregivers and require assistance with basic daily life activities. This study aims to measure the caregiver burden of informal caregivers of AD patients and to determine their characteristics. In addition, it intends to understand caregiver coping techniques and assess their medication knowledge. METHODS: This was a cross-sectional study including 148 informal caregivers mainly recruited by the Saudi Alzheimer's Disease Association (SADA). A four-part study questionnaire was used for data collection in the Arabic Language and included the following: socio-demographic characteristics of AD patients and their caregivers, the 12-item version of the Zarit Burden Interview (ZBI), and adapted questions on coping techniques and medication knowledge. RESULTS: A total of 148 caregivers (62% were female) participated in this study, and 79.06% were between 30 and 60 years old. The ZBI average score was 27, indicating a moderate to high burden. Caregivers reported their need for services to improve their quality of life. The medication knowledge was insufficient in most aspects except that more than half were aware of medications' side effects. CONCLUSION: Our study revealed that the average burden among informal caregivers of AD patients was moderate-high.

Knowledge, Attitude, and Perception of Health Care Providers Providing Medication Therapy Management (MTM) Services to Older Adults in Saudi Arabia.

INTRODUCTION: Medication Therapy Management (MTM) is identified as a group of services provided to the patient in order to optimize the medication use in order to mitigate adverse drug reactions (ADRs), drug-drug interaction (DDI), and polypharmacy. Elderly populations above 60 years old are at high risk for Medication-related Problems (MRPs) due to several factors. Therefore, MTM programs showed good contributions globally regarding enhancing medication use in the elderly population. Thus, evident information regarding its implementation in Saudi Arabia is lacking in the literature. OBJECTIVE: Our objective is to assess community pharmacists' knowledge, attitude, and barriers to providing MTM services to the older adult population in Saudi Arabia. METHODOLOGY: A cross-sectional study has been conducted among community pharmacists across the Kingdom. It was survey-based research that was designed and conducted through (QuestionPro). The survey was distributed for the community pharmacists from Feb-May 2023 via (QuestionPro). Descriptive analysis was performed using SAS OnDemand to analyze the categorical variables and test it with the outcome of interest. RESULTS: Out of the 528 participants who have viewed our questionnaire, 319 participants have completed the survey in 5 min average time. Most of our participants were male, holding a bachelor's degree, and had an average working load of more than 40 h a week, respectively (84.95%, 92.48%, and 76.18%). In addition, the participants were from different regions of the Kingdom, which enhanced the generalizability of our findings. Moreover, 65.52% have reported a higher level of knowledge, while 34.48% have reported a moderate to low level of knowledge regarding MTM service. Most of those with a higher level of knowledge maintain a positive attitude regarding MTM service, its implementation, and dealing with older adult patients in the community pharmacy. In addition, lacking the time, training, and presence of a private consultation room were the top barriers to provide MTM services in the community pharmacy in Saudi Arabia. CONCLUSION: Educational sessions regarding MTM services among the older adult population are highly recommended for community pharmacists before its implementation.

Diagnostic accuracy of large and medium vessel occlusions in acute stroke imaging by neurology residents and stroke fellows: A comparison of CT angiography alone and CT angiography with CT perfusion.

INTRODUCTION: Neurology senior residents and stroke fellows are first to clinically assess and interpret imaging studies of patients presenting to the emergency department with acute stroke. The aim of this study was to compare the diagnostic accuracy of brain CT angiography (CTA) with and without CT perfusion (CTP) between neurology senior residents and stroke fellows. METHODS: In this neuroimaging study, nine practitioners (four senior neurology residents (SNRs) and five stroke fellows (SFs)) clinically assessed and interpreted the imaging data of 50 cases (15 normal images, 21 large vessel occlusions (LVOs) and 14 medium vessel occlusions (MeVOs) in two sessions, 1 week apart in comparison to final diagnosis of experienced neuroradiologist and experienced stroke neurologist consensus. Interrater agreement of CTA alone and CTA with CTP was quantified using kappa statistics, sensitivity, specificity and overall accuracy. RESULTS: Overall, arterial occlusions were correctly identified in 221/315 (70.1%) with CTA alone and in 266/315 (84.4%) with CTA and CTP (p < 0.001). The sensitivity of overall arterial occlusions detection with CTA alone was 94.2% (95% CI: 90.8%-96.6%) while with addition of CTP was 98% (95% CI: 95.6%-99.3%), The specificity of CTA alone was 74.7% (95% CI: 67.2%-81.3%) which increased with CTP to 84.4% (95% CI: 77.7%-89.8%). The likelihood of correct identification with CTA alone was 156/189 (82.54%) for LVOs and 65/126 (51.59%) for MeVOs. This increased to 169/189 (89.42%; p = 0.054) for LVOs and 97/126 (76.98%; p < 0.001) for MeVOs when the CTA images with CTP were viewed. There was good overall interrater agreement between readers when using CTA alone (k 0.71, 95% CI, 0.62-0.80) and almost perfect (k 0.85, 95% CI, 0.76-0.94) when CTP was added to the image for interpretation. CTA and CTP had a significantly lower median interquartile range (IQR) interpretation time than CTA alone (114 [IQR, 103-120] s vs 156 [IQR, 133-160] s, p < 0.001). DISCUSSION: In cerebral arterial occlusions, the rate of LVO and MeVOs detections increases when adding CTP to CTA. The accuracy and time for diagnosing arterial occlusion can be significantly improved if CTP is added to CTA. As MeVOs are commonly missed by front-line neurology senior residents or stroke fellows, cases with significant deficits and no apparent arterial occlusions need to be reviewed with neuroradiological expertise.

Prevalence and associated factors of depression among elderly patients attending the primary health clinic in Prince Mansour Military Hospital in Taif, Saudi Arabia.

Background: Depression in the elderly is a common, debilitating, and costly condition. Little is known about the prevalence and correlates of geriatric depression in Saudi Arabia. This study evaluates the prevalence of depression among the elderly and its associated risk factors. Materials and Methods: A cross-sectional, questionnaire-based descriptive study was conducted on 259 elderly patients attending the Prince Mansour Military Hospital emergency department family medicine clinic in Taif city. Geriatric Depression Scale (GDS) was used. Results: The mean score was 4.4 (standard deviation [SD] = 2.56), ranging between 0 and 13. The median GDS score was 4. According to the results of this study, Cronbach's alpha for the GDS was 0.61 (95% confidence interval: 0.54-0.68). The prevalence of depression among the study participants was 43.2%. According to the GDS score categorization, 36.3% were mildly depressed, 4.2% were moderately depressed, and 2.7% were severely depressed. The adjusted effect was statistically significant for male gender (odds = 0.39, P < 0.001), older age (odds = 1.11, P = 0.007), diabetes mellitus (odds = 3.04, P = 0.02), asthma (odds = 25.94, P < 0.001), and renal failure (odds = 114.27, P = 0.03). Conclusion: Identification and treatment of geriatric depression should be prioritized by the family physicians in Saudi Arabia. Further research should focus on designing better culture-friendly geriatric depression screening tools.

The prevalence of coronaphobia among nursing staff in Saudi Arabia.

Background: Nursing staff are in direct contact with the consequences of the current coronavirus disease 2019 (COVID-19) crisis. Design and Methods: Descriptive questionnaire-based cross-sectional survey of a sample of nursing staff working across Saudi Arabia. Results: The study included (n = 431) nursing professionals. Coronaphobia prevalence among the nursing staff was 80.3% [95% confidence interval (CI): 76.5-84%]. There were (36.7%) who had severe cornaphobia. Working in a clinical department and being Saudi national were associated with increased COVID-19 fear (estimate = 0.109, P = 0.0153 and P = 0.010, respectively). Conclusion: Hospital management in Saudi Arabia needs to acknowledge the high prevalence of coronaphobia during the current COVID-19 crisis among nursing staff.

Screening for Cognitive Dysfunction in Amphetamine Users in Saudi Arabia; a Case-control Investigation Using Propensity Score Matching Analysis.

Amphetamine users have deficits in cognitive performance; however, the effects of duration and amount of use on cognitive decline remain elusive. The aim of this study was to evaluate the correlates of cognitive functioning in amphetamine users in Saudi Arabia. This was a case-control community-based study, using an Arabic adaptation of Addenbrooke's Cognitive Examination (ACE). The study compared users of amphetamine (n = 50) and controls (n = 50) in terms of performance on the ACE. Amphetamine users underperformed controls in the cognitive domains of attention, memory, language, fluency, and visuospatial faculties, even after controlling for psychiatric and sociodemographic variables. Heavy and prolonged use of amphetamine was associated with worse cognitive performance. Use of amphetamine at lower doses was not associated with worsening of cognitive functioning. The study adds to the evidence that amphetamine use is associated with impairment in cognitive functioning in Saudi Arabia. This has implications in terms of designing therapeutic interventions that account for potential cognitive difficulties in amphetamine abusers.
