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

J Psychoactive Drugs 2021 Apr 5:1-8. Epub 2021 Apr 5.

Department of Psychiatry, Armed Forces Center for Psychiatric Care, Taif, Saudi Arabia.

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.

Head and neck free tissue transfer in a patient with factor V Leiden: case report and review of the literature.

Oral Maxillofac Surg 2021 Jan 20. Epub 2021 Jan 20.

Department of Oral and Maxillofacial/Head and Neck Surgery, Division of Head and Neck Oncology and Reconstructive Surgery, LSU Health Sciences Center Shreveport, Shreveport, LA, USA.

Hypercoagulable disorders can compromise success of free flap reconstruction. Factor V Leiden is one such disorder for which only one previously reported case of successful free tissue transfer in the head and neck has been described. We report a 70-year-old woman with factor V Leiden treated for stage IVA squamous cell carcinoma of the mandible with a composite resection and reconstruction with an osteocutaneous scapular free tissue transfer. The free tissue transfer occurred without complications, in the setting of intraoperative heparin, postoperative aspirin, and enoxaparin. The free tissue transfer continues to be viable at her most recent follow-up appointment. The hypercoagulable patient represents a diverse presentation of increased coagulation risk in the perioperative period. Considering a patient's history and understanding available treatment adjuncts can factor heavily in a patient with factor V Leiden successfully undergoing free tissue transfer for head and neck defects.

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

Epilepsy Behav 2021 03 18;116:107712. Epub 2021 Jan 18.

Department of Neurosciences, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. Electronic address:

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.

Fear at the time of the COVID-19 pandemic: validation of the Arabic version of the Four-Dimensional Symptom Questionnaire among Saudi-based respondents.

BJPsych Open 2021 Jan 12;7(1):e33. Epub 2021 Jan 12.

Armed Forces Center for Psychiatric Care, Taif, Saudi Arabia.

Background: The COVID-19 pandemic has caused unprecedented stress and fear throughout the world.

Aims: To evaluate the psychological effects of the COVID-19 pandemic on the Saudi public, and to examine the performance of the Arabic version of the Four-Dimensional Symptom Questionnaire (4DSQ) scale.

Method: We conducted an online questionnaire-based cross-sectional survey of a sample of the Saudi public.

Results: The study included 347 participants, who reported significantly higher levels of distress, depressive symptoms, anxiety symptoms and somatisation compared with a normative sample. Females scored higher in terms of somatisation, depression and anxiety symptoms, and distress. Obtaining COVID-19 information from friends and relatives was associated with higher levels of somatisation, depression and anxiety symptoms, and distress. Cronbach's alpha was 0.93 for the distress scale, 0.88 for the depression scale, 0.88 for the anxiety scale and 0.86 for the somatisation scale.

Conclusions: Levels of psychological distress were high among the Saudi public during the COVID-19 pandemic. We found high reliability for the Arabic version of the 4DSQ scale. However, three items did not conform to the four-factor structure, namely, item 1: 'During the past week, did you suffer from dizziness or feeling light-headed?', item 20: 'During the past week, did you suffer from disturbed sleep?' and item 46: 'During the past week did you ever think I wish I was dead?'.

Effect of Conformance Control Patterns and Size of the Slug of In Situ Supercritical CO Emulsion on Tertiary Oil Recovery by Supercritical CO Miscible Injection for Carbonate Reservoirs.

ACS Omega 2020 Dec 15;5(51):33395-33405. Epub 2020 Dec 15.

Saudi Arabian Oil Company, Dhahran 31311, Kingdom of Saudi Arabia.

The reservoir heterogeneity is the major cause of poor volumetric sweep efficiency in sandstone and carbonate reservoirs. Displacing fluids (water, chemical solution, gas, and supercritical CO (sc-CO)) flow toward the high permeable zone. A significant fraction of oil remains in the low permeable zone due to the permeability contrast. This study used in situ sc-CO emulsion as a conformance control agent to plug the high permeable zone and improve the low permeable zone's volumetric sweep efficiency in carbonate formation. We investigated the effect of two types of conformance control patterns and the size of sc-CO emulsion on tertiary oil recovery performance by sc-CO miscible injection for carbonate reservoirs at reservoir conditions. The conformance control patterns are achieved using two different approaches. In the first approach, the low permeable zone was isolated, and the diverting gel system, a 0.4 pore volume slug, was injected into a high permeable zone. In the second approach, the simultaneous injection of the diverting gel system, a 0.2 pore volume slug, was done on both the low and high permeable zones. The first sc-CO injection was conducted as a tertiary oil recovery mode to recover the remaining oil after water flooding. The diverting gel system was injected after the first sc-CO flood for the conformance control. The second or post sc-CO injection was conducted after the diverting gel system injection. The diverting gel system used in this study consisted of a polymer and a surfactant. An in situ emulsion was generated when the injected diverting gel system interacts with the sc-CO in the core plug. Results obtained from dual-core core flooding experiments suggested that the in situ sc-CO emulsion was generated successfully in the formation based on the different pressure increases and observation of the dual-core core flooding experiments. The volumetric sweep efficiency and oil recovery in both conformance control patterns were improved. The production performances were also compared for both conformance control models before and after the diverting gel system injection. The conformance control model 2 (simultaneous injection of the diverting gel system into low and high permeability cores) has a better choice to be applied in field application due to high recovery with a small sc-CO2 emulsion easy operation in the field.

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

Gerontol Geriatr Educ 2020 Nov 3:1-10. Epub 2020 Nov 3.

Geriatrics Pharmacotherapy Program , Virginia Commonwealth University School of Pharmacy, Richmond, Virginia, USA.

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.

A Laboratory Session to Prepare Pharmacy Students to Manage the Opioid Crisis Situation.

Am J Pharm Educ 2019 09;83(7):6988

Virginia Commonwealth University School of Pharmacy, Richmond, Virginia.

To educate third-year pharmacy students about the role of pharmacists in the opioid crisis and measure their knowledge, confidence, and attitudes towards opioids and opioid overdose. All third-year students (n=130) enrolled in a Doctor of Pharmacy (PharmD) degree program participated in opioid overdose and naloxone education and training followed by a three-part laboratory session that included mock naloxone counseling, case-based discussion of the Prescription Drug Monitoring Program (PDMP), and equianalgesic opioid dose conversion scenarios. A pre- and post-assessment focused on the individual's clinical knowledge, confidence, and attitudes about opioid overdose management and naloxone use was administered before and after the laboratory session to evaluate the student's baseline understanding and experience compared to learning gains from the session. An evaluation of the laboratory session was also conducted. Upon completion, 99% percent of students rated the opioid laboratory as excellent (59%) or good (40%). Students believed the laboratory was stimulating (93%), relevant to pharmacy practice (96%), and contributed to their professional development (97%), and that the information provided was at an appropriate level (98%). Knowledge-based assessments improved in the areas of PDMP timely reporting, differentiating between naloxone devices, and naloxone administration technique. Student attitudes toward managing opioid overdoses improved on a majority of items. The majority of students agreed they had enough information to help them manage an opioid overdose (88.5%) and denied the need for additional training (61.5%). An active-learning laboratory helped to improve pharmacy students' knowledge, confidence, and attitudes with regard to opioids and the use of naloxone to treat a patient who has overdosed.

Comparison of broad-spectrum antibiotics and narrow-spectrum antibiotics in the treatment of lower extremity cellulitis.

Int J Health Sci (Qassim) 2018 Nov-Dec;12(6):3-7

Virginia Commonwealth University, School of Pharmacy, Richmond, Virginia.

Objective: Cellulitis is a commonly encountered medical illness and is most frequently caused by Group A β-hemolytic species and . The purpose of this study was to compare clinical outcomes of patients with lower extremity cellulitis treated with broad-spectrum and narrow-spectrum antibiotics.

Methods: This was a retrospective cohort study conducted in a community tertiary hospital between January 2016 and May 2016. Patients were included if they were diagnosed with uncomplicated non-purulent lower extremity cellulitis. Patients were divided into two groups: Individuals receiving narrow-spectrum antibiotics or receiving broad-spectrum antibiotics. Logistic regression analysis was used to estimate the odds ratio of repeat visit between the groups.

Results: A total of 599 patients with uncomplicated cellulitis were identified; of which 120 were included in the study (93 in narrow-spectrum arm and 27 in broad-spectrum arm). Repeat visit due to cellulitis was similar in both Groups 1 (4%) and 3 (3%) ( = 0.89) in the broad-spectrum arm and narrow-spectrum arm, respectively.

Conclusion: Broad-spectrum antibiotic use in uncomplicated cellulitis was common and unjustified given the results of our study. Implementation of clinical practice guidelines is recommended in limiting broad-spectrum antibiotics use in such population.

Medical apps used during advanced pharmacy practice experiences.

Curr Pharm Teach Learn 2018 02 21;10(2):195-200. Epub 2017 Oct 21.

Virginia Commonwealth University School of Pharmacy, United States. Electronic address:

Background And Purpose: The purpose of this study was to determine what type of medical applications (apps) are being used by fourth-year students during advanced pharmacy practice experiences (APPEs).

Educational Activity And Setting: Recent doctor of pharmacy school graduates were surveyed pertaining to their use of medical apps on APPEs, frequency of use for select apps, willingness to buy apps and at what cost, and their perceived importance on using medical apps in their pharmacy practice. The survey concluded by inquiring if medical apps should be taught in the pharmacy curriculum.

Findings: Ninety of 132 recent graduates responded to the survey and over 97% of the students used medical apps on their APPEs. Lexicomp, UpToDate and the Atherosclerotic Cardiovascular Disease (ASCVD) Risk calculator were the most frequently used applications during APPEs. Of those surveyed, 83% believe that medical apps should be taught in pharmacy school.

Discussion And Summary: Medical apps are frequently used on APPEs. It may be prudent to teach students how to use and evaluate medical apps before going on experiences so that students and patients can get the most benefit from these tools.

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

Am J Pathol 2017 Sep 20;187(9):2080-2094. Epub 2017 Jul 20.

Microvascular and Molecular Neuro-Oncology Laboratory, New York University Langone Medical Center, New York, New York; Department of Pathology, New York University Langone Medical Center, New York, New York; Division of Neuropathology, New York University Langone Medical Center, New York, New York; Department of Neurosurgery, New York University Langone Medical Center, New York, New York; New York University Langone Laura and Isaac Perlmutter Cancer Center, New York, New York. Electronic address:

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.

Student Knowledge, Skills, and Self-Efficacy Gains After Completing an Advanced Pharmacy Practice Experience in Geriatrics.

Am J Pharm Educ 2016 Nov;80(9):156

Virginia Commonwealth University School of Pharmacy, Richmond, Virginia.

To assess changes in pharmacy students' knowledge, skills, and self-efficacy after completing an advanced pharmacy practice experience (APPE) in geriatrics. During the 2013-2014 academic year, 30 Virginia Commonwealth University (VCU) School of Pharmacy students were required to complete a 5-week Geriatrics APPE at Plaza Professional Pharmacy in Richmond, Virginia. All students completed a 25-point knowledge-based pre- and post-assessment to measure students' self-efficacy. The average time required to accurately fill one unit dose prescription card before and after completing the APPE was also evaluated. Students' average score on the knowledge component improved significantly from 54% to 88% after completing the APPE. The average time required to fill one prescription decreased significantly from 4.0 minutes to 2.5 minutes. Students reported an increase in self-efficacy in the following areas: communication, immunizations, geriatrics-specific pharmacotherapy knowledge, and the ability to fill and check monthly unit dose prescription cards. Requiring fourth-year pharmacy students to complete a geriatrics APPE as a capstone experience to the integrated geriatrics content covered in the first through third years of the doctor of pharmacy (PharmD) curriculum provides an important opportunity to improve students' knowledge, skills, and self-efficacy in providing care to older adults.

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

J Oral Maxillofac Surg 2017 Aug 26;75(8):1743-1751. Epub 2016 Dec 26.

Head and Neck Tumor and Microvascular Reconstructive Surgery Fellow, University of Miami Miller School of Medicine, Miami, FL.

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.

Saudi Med J 2012 Oct;33(10):1053-8

Family Medicine Department, Taif Armed Forces Hospitals, Prince Mansour Military Hospital, PO Box 4232, Al-Taif, Kingdom of Saudi Arabia.

This paper presents a review to explore the literature focusing on portfolio in postgraduate general practice (GP) training, and to examine the impact of implementation of portfolio on learning process, as well as proposing recommendations for its implementation in postgraduate GP training. An electronic search was carried out on several databases for studies addressing portfolio in postgraduate GP training. Six articles were included to address specifically the effectiveness of portfolio in postgraduate GP training. Five of them described successful experiences of portfolio-based learning implementation. Only one article addressed portfolio-based assessment in postgraduate GP training. The existing evidence provides various benefits of professional portfolio-based learning. It does appear to have advantages of stimulating reflective learning, promoting proactive learning, and bridging the hospital experiences of the learners to GP. Moreover, the challenges to implementation of portfolio-based learning are often based on orientation and training of stakeholders.
