A robotic-assisted hybrid coronary revascularization program: Establishment and early experience in the Middle East.

BACKGROUND: Hybrid coronary revascularization (HCR) is a technique that merges coronary artery bypass grafting surgery and percutaneous coronary intervention (PCI) approaches for the treatment of multivessel coronary artery disease. The surgical component of the procedure is minimally invasive and can be done using robotic technology that avoids the need for sternotomy. Our objective is to study all patients who underwent robotic-assisted HCR (RHCR) to evaluate the feasibility and safety of the procedure during the establishment phase. METHODS: This study is a retrospective chart review conducted at King Faisal Specialist Hospital and Research Centre in Jeddah (KFSRC-J). The study focuses on patients who underwent RHCR between July 2018 to December 2020. The study was approved by the institutional review board #2020-103. RESULTS: Robotic-assisted HCR was performed on 78 patients (mean age, 56 years (range, 43-72 years); 89.75% males) during the study phase. Left internal mammary artery grafting was used in all patients. There was no hospital mortality, and the mean hospital and intensive care unit (ICU) stay were 5.8 and 1.4 days, respectively. We found that 93.6% of the patients had no blood transfusion. There were no major adverse cardiac events (MACE) and perioperative MI recorded. There was a 3.8% rate of postoperative complications. The percentage of surgeries converted to conventional and re-exploration for bleeding were 1.2% and 2.6%, respectively. The average operation time was 164 min. CONCLUSION: This study emphasizes on the safety and effectiveness of RHCR in treating patients with multivessel coronary artery disease. Moreover, robotic-assisted hybrid coronary revascularization offers an alternative, functionally complete revascularization option to a selected group of patients with minimal surgical trauma, short hospital and ICU length of stay, quick recovery, and little to no blood transfusion requirement.

Validity and Reliability of an Arabic Version of MD Anderson Dysphagia Inventory (MDADI).

Dysphagia is a common adverse event among head and neck (H&N) cancer patients. We aimed, for the first time, to validate the Arabic version of the MD Anderson Dysphagia Inventory (MDADI) among 82 Saudi Arabian patients with H&N cancer. We followed established validation guidelines and translated the 20-item MDADI using the forward-backward method. Our results revealed 100% feasibility. Test-retest reliability demonstrated acceptable interclass correlation coefficients (ICC) for the subscale domains (emotional = 0.973, physical = 0.971, and functional = 0.956) and composite score (ICC = 0.984). The Cronbach's alpha coefficients for the emotional, functional, and physical subscales were 0.937, 0.825, and 0.945, respectively (composite score = 0.975). We confirmed concurrent validity by demonstrating significant correlations between the domains of the Arabic MDADI and European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Head and Neck Module (QLQ-H&N35). Our study validated the Arabic version of the MDADI among H&N cancer patients from Saudi Arabia.

Caregiver burden among family caregivers of incurable cancer patients in two eastern Mediterranean countries.

BACKGROUND: Although family caregivers (FCs) play an important role in the care provided to incurable cancer patients in our region, little is known about the burden they experience. This study was conducted to determine the prevalence of caregiver burden (CB) among FCs of incurable cancer patients in two Eastern Mediterranean countries and to identify factors that may be associated with significant CB. METHODS: The study included 218 FCs, 165 from Egypt and 53 from Saudi Arabia. The 22-item Zarit Burden Interview (ZBI-22) was used to assess caregiver burden CB. Significant CB was defined as a ZBI-22 score ≥ 21. The assistance with basic ADLs was classified into 3 levels according to FCs' assistance with early/middle/late-loss basic ADLs. The relationship between CB and the assistance with ADLs and other factors was studied. RESULTS: The mean (SD) ZBI-22 score among FCs was 23.4 (9.3) and the majority (128/218, 59%) had significant CB. Eighty-nine percent of FCs assisted with at least one basic ADL. Assistance with late-loss basic ADLs, best supportive care treatment plan and poorer performance status were associated with higher CB (p < 0.0001, =0.018 and = 0.005). However, in logistic regression analysis, only assistance with late-loss ADLs was independently associated with significant CB (OR = 3.4 [95%CI:1.2-9.7], p = 0.024). CONCLUSION: A substantial proportion of FCs of incurable cancer patients in our region experience significant CB. Family caregivers assisting with late-loss basic ADLs are at risk of significant CB and should be routinely screened for CB.

Anterior circulation large vessel occlusion stroke in Saudi Arabia: Prevalence, predictors, and outcome.

OBJECTIVE: Anterior circulation Large Vessel Occlusion (LVO) stroke comes with significant morbidity and mortality. With the advent of endovascular interventions, its management has revolutionized. For health authorities to build systems and allocate resources, its burden, predictors, and outcome must be determined. METHODS: In a single tertiary care center, we retrospectively collected data from 1495 ischemic stroke patients to determine anterior circulation LVO prevalence, predictors, and outcome. Patients must have radiologically proven ischemic stroke within 24 hours before arrival at the emergency department. Anterior circulation LVO related stroke was defined as evidence of new anterior circulation infarct detected on neuroimaging, and vascular imaging confirming anterior circulation Large Vessel Occlusion. Data on demographics, vascular risk factors, treatment with reperfusion therapy, modified Rankin Scale (mRS) at admission, National Institute of Health Stroke Scale (NIHSS) at admission, length of stay (LOS) in days, and in-hospital comorbidities and death were collected. Regression analysis was done to determine the predictors and outcomes of anterior circulation LVO ischemic strokes. RESULTS: We found anterior circulation LVO in 27.8% (95 % CI 25.5-30.0) of all ischemic stroke patients. Atrial fibrillation and admission National Institute of Health Stroke Scale (NIHSS) were the strongest predictors of LVO [OR 2.33, P = 0.0011 and OR 1.17, P < 0.0001] respectively. Occurrence of LVO was associated with worse disability score (mRS ≥ 3) [47.22 vs. 19.81% (P = 0.0073)], longer hospitalization in days [Median 9.0 vs. 3.0, IQR (14.0 vs. 5.0) P = 0.0432)], and was more likely to results in patient admission to intensive care unit [Mean 17.59 vs. 3.70 % (P = 0.0002)]. CONCLUSION: Stroke with large vessel occlusion in Saudi Arabia is not uncommon. Its burden and outcome deserve national attention, as effective treatment is now readily available.

Stroke and high-risk TIA outcomes with reduction of treatment duration when treatment initiated in emergency rooms (SHORTER-study).

BACKGROUND: Following transient ischemic attack (TIA) and minor stroke, the risk of recurrent stroke can be significantly reduced with short-duration dual antiplatelet therapy (DAPT). We wish to investigate whether 10 days of DAPT is as effective as 21 days' treatment. STUDY DESIGN: This is an open-label, randomized, parallel-group study comparing whether 10 days of DAPT treatment (ASA + clopidogrel) is non-inferior to 21 days of DAPT in patients with acute ischemic stroke (AIS) or high-risk TIA. In both groups, DAPT is started within 24 hours of symptom onset. This study is being conducted in approximately 15 study sites in the Kingdom of Saudi Arabia. The planned sample size is 1932. OUTCOMES: Non-inferiority of 10 days compared to 21 days of DAPT in the prevention of the composite endpoint of stroke and death at 90 days in AIS/TIA patients. The primary safety outcome is major intra-cranial and systemic hemorrhage. STUDY PERIOD: Enrolment started in the second quarter of 2023, and the completion of the study is expected in the fourth quarter of 2025. DISCUSSION: The trial is expected to show that 10 days of DAPT is non-inferior for the prevention of early recurrence of vascular events in patients with high-risk TIAs and minor strokes.

Minimally-invasive approach via percutaneous femoral cannulation for the resection of intra-cardiac masses: a single center experience in the Middle-East.

BACKGROUND: Intra-cardiac masses are rare and challenging lesions with an overall incidence ranging of 0.02-0.2%. Minimally invasive approaches have been recently introduced for surgical resection of these lesions. Here, we evaluated our early experience using minimally invasive techniques in addressing intra-cardiac lesions. METHODOLOGY: This is a retrospective descriptive study conducted between April 2018 to December 2020. All patients were diagnosed with cardiac tumors and treated via a right mini-thoracotomy with cardiopulmonary bypass through femoral cannulation at King Faisal Specialist Hospital and Research Centre, Jeddah. RESULTS: Myxoma was the most common pathology representing 46% of cases followed by thrombus (27%), leiomyoma (9%), lipoma (9%) and angiosarcoma (9%). All tumors were resected with negative margins. One patient was converted to open sternotomy. Tumor locations were in the right atrium, left atrium, and left ventricle in 5, 3, and 3 patients, respectively. The median ICU stay was 1.33 days. The median length of hospitalization was 5.7 days. There was no 30-days hospital mortality recorded in this cohort. CONCLUSION: Our early experience shows that minimally invasive resection can be performed safely and effectively for intra-cardiac masses. The minimally invasive approach using a mini-thoracotomy with percutaneous femoral cannulation can be an effective alternative in resecting intra-cardiac masses that achieves clear margin resection, quick post-operative recovery, and low rates of recurrence for benign lesions.

Compliance with contact lens care and factors driving noncompliance in health-care students in Jeddah, Saudi Arabia.

PURPOSE: This study aimed to assess compliance to contact lens care behaviors and determine common factors influencing noncompliance among a population of university students in Jeddah, Saudi Arabia. METHODS: This is an observational, cross-sectional study in which a previously validated self-administered questionnaire consisting of 12 questions addressing compliance to contact lens wear and care was E-mailed through the university message center. RESULTS: A total of 388 participants completed the questionnaire. Of those who completed the survey, 150 were contact lens users with an experience of 1 month or more. The average compliance rate to contact lens care was around 66%. High levels of compliance were reported in sharing contact lenses, sleeping with contact lenses, showering/swimming with contact lenses, and using water to clean contact lenses. Moderate levels of compliance were shown in overuse of contact lenses, adherence to instructions of lens cleaning, cleaning the lens case, and adherence to aftercare visits. The lowest levels of compliance were noted in washing hands before lens use and lens case replacement. Gender, smoking, contact lens experience, type and modality of contact lens usage, and contact lens purchase site were found to have a significant association with behaviors showing poor compliance. Believing there is no harm in wearing lenses for longer than the recommended replacement schedule was the primary reason given for overusing contact lenses. CONCLUSION: Moderate levels of compliance were generally reported by respondents, necessitating the need for better strategies to reinforce the importance of compliance to contact lens care in the Saudi population.

Eustachian Tube Dysfunction Improvement Secondary to Moderate Weight Loss: Case Report.

The Eustachian tube (ET) is an osteocartilaginous canal that connects the middle ear to the nasopharynx. It is one of the critical structures essential for middle ear functions. ET dysfunction causes discomfort in the affected ear and decreased hearing. This is the first case report of improving hearing and middle ear aeration and ET function secondary to body weight reduction. A 27-year-old male patient presented to the otology clinic complaining of decreased hearing for two years. Initial ear examination revealed retraction of TM on the left ear with two retraction pockets, and on the right ear, the TM was dull with one retraction pocket. The patient reported losing some of his body weight during those six months. Ear examination revealed improvement in the TM retraction in both ears. The improvement in hearing was evidenced by a serial audiogram, while the middle ear aeration was evidenced by clinical examination.

Ischemic Stroke Secondary to Dynamic Vertebral Artery Stenosis: Case Report and Review of the Literature.

Ischemic stroke secondary to dynamic vertebral artery stenosis or occlusion, also known as "bow hunter's syndrome," is a rare stroke mechanism. We report a case of a 24-year-old man with multiple hereditary exostosis (MHE) diagnosed at childhood. His first presentation to a neurologist was due to neck pain and clinical syndrome suggestive of ischemia in the vertebrobasilar territory. A therapeutic occlusion was done successfully without complication. The patient was discharged two days later on aspirin alone. In follow up one year later he continued to be symptom free. Moreover, this stroke mechanism has been reported extensively in the literature in isolation or secondary to many underlying diseases. In total, there are 168 cases reported in the published English literature, in either case reports or small series. In this review, we found that by far, vertebral artery occlusion at the atlanto-axial (C1-2) level dominated most reported cases. The most frequent presentation that led to further investigation was syncope or pre-syncope provoked by head rotation to one side. To our knowledge, there is no previous report of any stroke syndrome related to MHE before our case. In this paper, we report the first case secondary to MHE and review the literature up to date since the first reported case in 1952.

Guidelines for cochlear implantation in Saudi Arabia.

This study aim to establish unified clinical practice guidelines (CPGs) for adults and pediatric cochlear implantation (CI) for the Ministry of Health specialist hospitals in the Kingdom of Saudi Arabia. A comprehensive literature review was carried out by a task force group. Guidelines were based on evidence-based medicine including institutions and individuals' experiences. Bilateral CI is recommended for adults and pediatrics with bilateral severe/profound hearing loss. The minimum age of implantation for children is recommended at 9 months. This study provides a safe framework for the multidisciplinary team to select appropriate CI candidates. It is important to establish a comprehensive multidisciplinary team covering different aspects of health care providers.

Stroke Seasonality and Weather Association in a Middle East Country: A Single Tertiary Center Experience.

Background: Stroke is a medical condition that leads to major disability and mortality worldwide. Some evidence suggests that weather and seasonal variations could have an impact on stroke incidence and outcome. However, the current evidence is inconclusive. Therefore, this study examines the seasonal variations and meteorological influences on stroke incidence and outcome in the largest city in Saudi Arabia. Methods: From February 2016 to July 2019, we retrospectively reviewed data from all patients with acute ischemic (AIS) or hemorrhagic stroke (HS) admitted to the stroke unit in a tertiary academic center in Saudi Arabia. The corresponding daily meteorological data were obtained for the same period. We considered the months from November to March as the cold season and April to October as the hot season. Results: The final cohort included 1,271 stroke patients; 60.89% (n = 774) cases occurred in the hot season, while 39.1% (n = 497) in the cold season. Males accounted for 69.6% (n = 884) of the cases. The proportion of ischemic stroke was 83.2% [hot season 83.9% (n = 649) vs. cold season 82.3% (n = 409)]. We found no statistically significant difference between seasons (hot or cold) in stroke incidence, severity [National Institutes of Health Stroke Scale (NIHSS)], hospital course (pneumonia, thromboembolism, intensive care stay, or length of stay), or outcome [modified Rankin scale (mRS) on discharge and death]. Conclusions: In Riyadh, Saudi Arabia, our study found no impact of weather or seasonal variations on stroke incidence, hospital course, or outcomes. However, our findings warrant further research in different country regions.

Role of fine-needle aspiration cytology in evaluating thyroid nodules. A retrospective study from a tertiary care center of Western region, Saudi Arabia.

OBJECTIVES: To evaluate the accuracy and e cacy of ne-needle aspiration cytology (FNAC) in diagnosing thyroid nodules, correlating it with the histopathological findings. METHODS: A retrospective evaluation of 314 patients was undertaken at a tertiary referral center of King Abdullah Medical City (KAMC), Makkah, Kingdom of Saudi Arabia, between 2010-2019. Patients who presented with thyroid swellings underwent ultrasonography and FNAC. If indicated, surgery was performed. The FNAC findings were compared to the final histopathological reports. RESULTS: The findings for FNAC from our data set of 314 patients showed a sensitivity value of 79.8%, specificity of 82.1%, accuracy of 74.8%, positive predictive value of 74.8%, and negative predictive value of 85.9%. Conclusion: Our study showed that FNAC has high sensitivity and speci city in the initial evaluation of patients with thyroid nodules. When guided by ultrasonography, the accuracy can be markedly improved. Molecular markers once widely available can improve the diagnostic power of FNAC to be no less than the histopathologic evaluation of thyroid tissue.
