Using Machine Learning to Predict Outcomes Following Transfemoral Carotid Artery Stenting.

Background: Transfemoral carotid artery stenting (TFCAS) carries important perioperative risks. Outcome prediction tools may help guide clinical decision-making but remain limited. We developed machine learning algorithms that predict 1-year stroke or death following TFCAS.

Predicting Outcomes Following Lower Extremity Endovascular Revascularization Using Machine Learning.

Background: Lower extremity endovascular revascularization for peripheral artery disease carries nonnegligible perioperative risks; however, outcome prediction tools remain limited. Using machine learning, we developed automated algorithms that predict 30-day outcomes following lower extremity endovascular revascularization.

Methods And Results: The National Surgical Quality Improvement Program targeted vascular database was used to identify patients who underwent lower extremity endovascular revascularization (angioplasty, stent, or atherectomy) for peripheral artery disease between 2011 and 2021.

Complete response of mantle cell lymphoma with central nervous system involvement at diagnosis with acalabrutinib - Case report.

Central nervous system (CNS) involvement by mantle cell lymphoma (MCL) is rare and portends a poor prognosis. We describe the first patient to have a complete response with front-line treatment with single-agent acalabrutinib for MCL CNS.

Occult Diastolic Dysfunction and Adverse Clinical Outcomes in Adolescents and Young Adults With Fontan Circulation.

Background In Fontan circulation, diastolic dysfunction portends a worse clinical outcome but may be concealed during routine assessment. Invasive evaluation with rapid volume expansion (RVE) can identify patients with occult diastolic dysfunction (ODD). We sought to evaluate the association between ODD and adverse clinical outcomes at medium-term follow-up.

Biallelic Loss-of-Function Variants Cause a Wide Phenotypic Spectrum from Leigh/Leigh-Like Syndrome to Isolated Optic Atrophy.

Background: Biallelic loss-of-function variants have hitherto been linked to mitochondrial complex I deficiency presenting with heterogeneous clinical and radiological features in nine cases only.

Objectives: To fully characterize, both phenotypically and genotypically, -related mitochondrial disease.

Methods: We collected data from cases identified by screening genetic databases of several laboratories worldwide and systematically reviewed the literature.

SLC25A42-associated mitochondrial encephalomyopathy: Report of additional founder cases and functional characterization of a novel deletion.

SLC25A42 is the main transporter of coenzyme A (CoA) into mitochondria. To date, 15 individuals have been reported to have one of two bi-allelic homozygous missense variants in the as the cause of mitochondrial encephalomyopathy, of which 14 of them were of Saudi origin and share the same founder variant, c.871A > G:p.

The outcomes of secondary AML post allogeneic hematopoietic cell transplantation significantly depend on the presence of poor-risk cytogenetic abnormalities.

Secondary acute myeloid leukemia (sAML) includes AML as a complication of an antecedent hematological disorder or a therapy-related AML. Large registry-based data identified sAML as an independent poor-outcome type of AML post allogeneic hematopoietic cell transplantation (allo-HCT). In our study, we tried to define factors affecting outcomes of sAML post allo-HCT, and identify patients with sAML who may truly benefit from allo-HCT.

Non-acute promyelocytic leukemia variant, acute myeloid leukemia with translocation (11;17).

t(11;17) is a rare but recognized finding usually found in Acute Promyelocytic Leukemia with variant translocation (APLv). We present a case of Acute Myeloid Leukemia with t(11;17) that has different break points than those occurring in APLv. The diagnosis of acute myeloid leukemia, not otherwise specified, acute monoblastic leukemia was reached after a thorough investigation.

The association between platelet transfusions and bleeding in critically ill patients with thrombocytopenia.

Background: Platelet transfusions are commonly used to treat critically ill patients with thrombocytopenia. Whether platelet transfusions are associated with a reduction in the risk of major bleeding is unknown.

Patients/methods: Observational cohort study nested in a previous multicenter, randomized thromboprophylaxis trial in the intensive care unit (ICU).

Public Awareness and Knowledge of Pap Smear as a Screening Test for Cervical Cancer among Saudi Population in Riyadh City.

Aims: To explore the public awareness, knowledge, and attitudes of Saudi women towards Pap smear as a screening test for cervical cancer.

Methods: A descriptive cross-sectional study took place in four major secondary and tertiary healthcare hospitals located in the capital city Riyadh between January 2016 and June 2016. A self-administered, coded, close-ended survey was randomly distributed to 1000 non-single women attending the obstetrics/gynecology outpatient clinics or inpatient wards.

Specialty Preferences and the Factors Influencing Them Among Pre-Clerkship Medical Students: The First Study from Alfaisal University-College of Medicine, Saudi Arabia.

Aim: To explore the specialty preferences and the factors influencing them among pre-clerkship (second-year and third-year) medical students at Alfaisal University-College of Medicine, Riyadh, Saudi Arabia.

Methods: An online, anonymous, cross-sectional, self-rating survey was administered. The survey explored socio-demographical data, specialty preferences and the factors influencing such preferences.
