Combining Novel Thrombectomy Devices for Intracardiac Mass Extraction: The Kong and Godzilla of Mass Extraction.

Transcatheter extraction of an intracardiac mass is a newer approach that may lead to nonsurgical treatment of complex cardiac masses. We present a case in which thrombectomy devices were combined to extract a right atrial mass, which highlights new frontiers in the treatment of complex transcatheter mass extraction. The combined use of two transcatheter thrombectomy devices (Kong and Godzilla) may provide a powerful addition to the existing armamentarium.

Immunological, histological and immunohistochemical alternations induced by zinc oxide nanoparticles and mureer plant in spleen albino rats with the prospective anti-inflammatory action of gallic acid.

The current study was proposed to evaluate the mortal impacts of either alone or mixed treatments of zinc oxide nanoparticles (ZnO NPs) and mureer or Senecio glaucus L. plant (SP) on spleen tissue via immunological and histological studies and to estimate the likely immunomodulatory effect of gallic acid (GA) for 30 days in rats. Rats were classified into eight groups with orally treated: Control, GA (100mg/kg), ZnO NPs (150mg/kg), SP (400mg/kg), GA+ZnO NPs (100,150mg/kg), GA+SP (100,400mg/kg), ZnONPs+SP (150,400mg/kg) and GA+ZnONPs+SP (100,150,400mg/kg). Interleukin-6 (IL-6) level was measured using an enzyme-linked immunoassay (ELISA). Also, the pro-apoptotic protein (caspase-3) expression was estimated using an immunohistochemistry assay. Our data revealed that ZnO NPs and SP triggered a significant increase in the levels of IL-6 and total lipids (TL) and the activity of lactate dehydrogenase (LDH), (p<0.001). Furthermore, they overexpressed caspase-3 and caused lymphoid depletion. They revealed that the immunotoxic outcome of mixed treatment was more than the outcome of the alone treatment. However, GA restored the spleen damage from these adverse results. Finally, this study indicated that ZnO NPs and SP might be immunotoxic and splenotoxic agents; however, GA may be displayed as an anti-inflammatory and splenic-protective agent.

Characterization of the equine placental microbial population during nocardioform placentitis.

Nocardioform placentitis is a poorly understood disease of equine late gestation. The presence of nocardioform, filamentous branching gram-positive bacteria, has been linked to the disease, with Crossiella equi, Amycolatopsis spp., and Streptomyces spp. being the most frequently identified bacteria. However, these bacteria are not found in all clinical cases in addition to being isolated from healthy, normal postpartum placentas. To better understand this form of placentitis, we analyzed the microbial composition in the equine placenta (chorioallantois) of both healthy postpartum (control; n = 11) and nocardioform-affected samples (n = 22) using 16S rDNA sequencing. We found a lower Shannon index in nocardioform samples, a higher Chao1 index in nocardioform samples, and a difference in beta diversity between control and nocardioform samples (p < 0.05), suggesting the presence of dysbiosis during the disease. In the majority of the NP samples (77 %), one of the following genera-Amycolatopsis, Crossiella, Lentzea, an unidentified member of the Pseudonocardiaceae family, Mycobacterium, or Enterococcus -represented over 70 % of the relative abundance. Overall, the data suggest that a broader spectrum of potential opportunistic pathogens could be involved in nocardioform placentitis, extending beyond the traditionally recognized bacteria, resulting in a similar histomorphological profile.

Mapping Genetic Markers Associated with Antigenicity and Host Range in H9N2 Influenza A Viruses Infecting Poultry in Pakistan.

The aim of the current study was to map the genetic diversity in the haemagglutinin (HA) glycoprotein of influenza A viruses (IAVs) of the H9N2 subtype. Twenty-five H9N2 IAVs were isolated from broiler chickens from March to July 2019. The HA gene was amplified, and phylogenetic analysis was performed to determine the evolutionary relationship. Important antigenic amino acid residues of HA attributed to immune escape and zoonotic potential were compared among H9N2 IAVs. Phylogenetic analysis revealed that sublineage B2 under the G1 lineage in Pakistan was found to be diversified, and newly sequenced H9N2 isolates were nested into two clades (A and B). Mutations linked to the antigenic variation and potential immune escape were observed as G72E (1/25, 4%), A180T (3/25, 12%), and A180V (1/25, 4%). A twofold significant reduction (P < 0.01) in log2 hemagglutination inhibition titers was observed with H9N2 IAV naturally harboring amino acid V180 instead of A180 in HA protein. Moreover, in the last 20 years, complete substitution at residues (T127D, D135N, and L150N) and partial substitution at residues (72, 74, 131, 148, 180, 183, 188, 216, 217, and 249, mature H9 HA numbering) associated with changes in antigenicity were observed. The presence of L216 in all H9N2 IAV isolates and T/V180 in four isolates in the receptor-binding site reveals the potential of these viruses to cross the species barrier to infect human or mammals. The current study observed the circulation of antigenically diverse H9N2 IAV variants that possess potential mutations that can escape the host immune system.

Nota de investigación- Mapeo de marcadores genéticos asociados con la antigenicidad y el rango de huéspedes en los virus de la influenza tipo A subtipo H9N2 que infectan a la avicultura en Pakistán. El objetivo del presente estudio fue mapear la diversidad genética en la glicoproteína hemaglutinina (HA) de los virus de la influenza A (IAV) del subtipo H9N2. Se aislaron veinticinco virus de influenza H9N2 de pollos de engorde de marzo a julio del 2019. Se amplificó el gene HA y se realizó un análisis filogenético para determinar la relación evolutiva. Se compararon importantes residuos de aminoácidos antigénicos de la hemaglutinina atribuidos al escape inmunológico y al potencial zoonótico entre los virus de la influenza aviar H9N2. El análisis filogenético reveló que el sublinaje B2 bajo el linaje G1 en Pakistán estaba diversificado, y los aislados de H9N2 recién secuenciados se agruparon en dos clados (A y B). Se observaron mutaciones relacionadas con la variación antigénica y el posible escape inmunológico como los residuos de aminoácidos G72E (1/25, 4%), A180T (3/25, 12%) y A180V (1/25, 4%). Se observó una reducción significativa al doble (P < 0.01) en los títulos de inhibición de la hemaglutinación log2 cuando el virus de la influenza aviar H9N2 albergaba naturalmente el aminoácido V180 en lugar del A180 en la proteína HA. Además, en los últimos 20 años, sustitución completa en los residuos (T127D, D135N y L150N) y sustitución parcial en los residuos (72, 74, 131, 148, 180, 183, 188, 216, 217 y 249, de acuerdo con la numeración de la HA subtipo madura) asociados con cambios en la antigenicidad. La presencia del residuo L216 en todos los aislados de influenza aviar H9N2 y T/V180 en cuatro aislados en el sitio de unión al receptor revela el potencial de estos virus para cruzar la barrera de las especies para infectar a humanos o mamíferos. El estudio actual observó la circulación de variantes antigénicamente diversas del virus de influenza aviar H9N2 que poseen mutaciones potenciales que pueden escapar del sistema inmunológico del huésped.

Small Cell Neuroendocrine Carcinoma of the Vagina: A Rare Presentation.

Primary small cell neuroendocrine carcinoma of the vagina is a very rare disease. We present a case study of a 52-year-old female who presented to the hospital with complaints of urinary dribbling, burning micturition, pain, and per vaginal bleeding for three to four months. A firm globular mass of approximately 5-6 cm was felt in the anterior vaginal wall per speculum examination. Diagnosis of small cell neuroendocrine carcinoma was made with tissue biopsy and immunohistochemistry. Diagnostic imaging (MRI, positron emission tomography (PET)-CT) plays a vital role in reaching the diagnosis and understanding the treatment response. The patient received six cycles of chemotherapy with cisplatin and etoposide and radiotherapy, achieving a complete response, with complete regression of the lesion. The patient had no sign of tumor recurrence and locoregional or distant metastases after six months of follow-up. Nowadays, there is no need for surgery in the treatment of vaginal small cell neuroendocrine carcinoma, rather radiotherapy and chemotherapy are the treatment of choice. We report a case of neuroendocrine cancer of the vagina treated at our institution.

Advanced methods of algal pigments extraction: A review.

Algae are exclusively aquatic photosynthetic organisms that are microscopic or macroscopic, unicellular or multicellular and distributed across the globe. They are a potential source of food, feed, medicine and natural pigments. A variety of natural pigments are available from algae including chlorophyll a, b, c d, phycobiliproteins, carotenes and xanthophylls. The xanthophylls include acyloxyfucoxanthin, alloxanthin, astaxanthin, crocoxanthin, diadinoxanthin, diatoxanthin, fucoxanthin, loroxanthin, monadoxanthin, neoxanthin, nostoxanthin, perdinin, Prasinoxanthin, siphonaxanthin, vaucheriaxanthin, violaxanthin, lutein, zeaxanthin, ß-cryptoxanthin, while carotenes include echinenone, α-carotene, ß-carotene, γ-carotene, lycopene, phytoene, phytofluene. These pigments have applications as pharmaceuticals and nutraceuticals and in the food industry for beverages and animal feed production. The conventional methods for the extraction of pigments are solid-liquid extraction, liquid-liquid extraction and soxhlet extraction. All these methods are less efficient, time-consuming and have higher solvent consumption. For a standardized extraction of natural pigments from algal biomass advanced procedures are in practice which includes Supercritical fluid extraction, Pressurized liquid extraction, Microwave-assisted extraction, Pulsed electric field, Moderate electric field, Ultrahigh pressure extraction, Ultrasound-assisted extraction, Subcritical dimethyl ether extraction, Enzyme assisted extraction and Natural deep eutectic solvents. In the present review, these methods for pigment extraction from algae are discussed in detail.

A Critical Review of Icosapent Ethyl in Cardiovascular Risk Reduction.

Icosapent ethyl (IPE) was the first fish oil product the US Food and Drug Administration (FDA) approved to reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in adults. IPE is an esterified version of eicosapentaenoic acid (EPA) and acts as a prodrug in the body to exert its effects. IPE affects the body primarily through triglyceride (TG) reduction and was initially indicated for hypertriglyceridemia in addition to statin therapy or for patients with statin intolerances. Various studies have investigated this agent, and multiple subanalyses have been conducted since the FDA approval. These subanalyses have assessed factors such as sex, statin therapy, high-sensitivity C-reactive protein levels (hs-CRP), and various inflammatory biomarkers in groups of patients taking IPE. This article aims to provide a critical review of the clinical data available regarding cardiovascular benefits of IPE in patients with ASCVD and its value as a treatment option for patients with elevated TG levels.

Characterization of the equine placental microbial population in healthy pregnancies.

In spite of controversy, recent studies present evidence that a microbiome is present in the human placenta. However, there is limited information about a potential equine placental microbiome. In the present study, we characterized the microbial population in the equine placenta (chorioallantois) of healthy prepartum (280 days of gestation, n = 6) and postpartum (immediately after foaling, 351 days of gestation, n = 11) mares, using 16S rDNA sequencing (rDNA-seq). In both groups, the majority of bacteria belonged to the phyla Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidota. The five most abundant genera were Bradyrhizobium, an unclassified Pseudonocardiaceae, Acinetobacter, Pantoea, and an unclassified Microbacteriaceae. Alpha diversity (p < 0.05) and beta diversity (p < 0.01) were significantly different between pre- and postpartum samples. Additionally, the abundance of 7 phyla and 55 genera was significantly different between pre- and postpartum samples. These differences suggest an effect of the caudal reproductive tract microbiome on the postpartum placental microbial DNA composition, since the passage of the placenta through the cervix and vagina during normal parturition had a significant influence on the composition of the bacteria found in the placenta when using 16S rDNA-seq. These data support the hypothesis that bacterial DNA is present in healthy equine placentas and opens the possibility for further exploration of the impact of the placental microbiome on fetal development and pregnancy outcome.

Dynamics of the Equine Placental DNA Methylome and Transcriptome from Mid- to Late Gestation.

The placenta is a temporary organ that is essential for the survival of the fetus, with a lifelong effect on the health of both the offspring and the dam. The functions of the placenta are controlled by its dynamic gene expression during gestation. In this study, we aimed to investigate the equine placental DNA methylome as one of the fundamental mechanisms that controls the gene expression dynamic. Chorioallantois samples from four (4M), six (6M), and ten (10M) months of gestation were used to map the methylation pattern of the placenta. Globally, methylation levels increased toward the end of gestation. We identified 921 differentially methylated regions (DMRs) between 4M and 6M, 1225 DMRs between 4M and 10M, and 1026 DMRs between 6M and 10M. A total of 817 genes carried DMRs comparing 4M and 6M, 978 comparing 4M and 10M, and 804 comparing 6M and 10M. We compared the transcriptomes between the samples and found 1381 differentially expressed genes (DEGs) when comparing 4M and 6M, 1428 DEGs between 4M and 10M, and 741 DEGs between 6M and 10M. Finally, we overlapped the DEGs and genes carrying DMRs (DMRs-DEGs). Genes exhibiting (a) higher expression, low methylation and (b) low expression, high methylation at different time points were identified. The majority of these DMRs-DEGs were located in introns (48.4%), promoters (25.8%), and exons (17.7%) and were involved in changes in the extracellular matrix; regulation of epithelial cell migration; vascularization; and regulation of minerals, glucose, and metabolites, among other factors. Overall, this is the first report highlighting the dynamics in the equine placenta methylome during normal pregnancy. The findings presented serve as a foundation for future studies on the impact of abnormal methylation on the outcomes of equine pregnancies.

The effect of Acacia nilotica bark extract on growth performance, carcass characteristics, immune response, and intestinal morphology in broilers as an alternative to antibiotic growth promoter.

OBJECTIVE: Present study was designed to evaluate the efficacy of Acacia nilotica bark extract as an alternative to antibiotic growth promoters in broilers. METHODS: Six hundred, day-old broiler chicks were randomly divided into six groups (NC, without any supplementation; AB, NC+Zinc Bacitracin; PB, NC+Safmannan; ANBE1, NC+A. nilotica bark extract 0.1%; ANBE3, NC+A. nilotica bark extract 0.3%; ANBE5, NC+A. nilotica bark extract 0.5%), with ten replicates per group (10 chicks/replicate) and feeding trial was lasted for 35 days. RESULTS: Results showed that weight gain (1,296.63 g) and feed conversion ratio (FCR, 1.59) of AB was better than NC, during the finisher phase. Overall FCR of AB (1.53), PB (1.54), and ANBE5 (1.54) was significantly (p<0.05) better than NC. From carcass parameters relative weight of wing and heart were highest in ANBE3 (2.5% and 1.51%, respectively). Significantly (p<0.05) highest blood glucose level was observed in NC (264.5 mg/dL) and highest albumin concentration was found in AB (1.46 mg/dL). In addition, antibody titer levels against ND and IBD were higher in ANBE5 than NC, while higher relative weight of bursa was observed in ANBE3 than NC. The villus height to crypt depth ratio in all experimental groups was better than NC. CONCLUSION: Acacia nilotica bark extract could be a suitable alternative to antibiotic growth promoters to support the growth in broilers.

Transcriptomic analysis of the chorioallantois in equine premature placental separation.

BACKGROUND: Equine premature placental separation (PPS) is poorly understood and represents an important risk factor for fetal/neonatal hypoxia. OBJECTIVES: To examine transcriptomic changes in the chorioallantois (CA) from mares with clinical PPS compared with the CA from normal foaling mares. Differential gene expression was determined and gene ontology as well as molecular pathways related to PPS were characterised. STUDY DESIGN: Retrospective case: control study. METHODS: CA were collected from Thoroughbred mares with a clinical history of PPS (n = 33) and from control Thoroughbred mares (n = 4) with normal parturition for examination of transcriptional changes in the placenta associated with PPS. Transcriptomic changes in the villous CA near the cervical star were determined by Illumina® sequencing and subsequent bioinformatic analysis. PPS samples were divided by k-means clustering, and differentially expressed genes (DEGs) in each PPS cluster were identified by comparing to controls. Shared DEGs between PPS clusters were used for gene ontology analysis and pathway analysis. RESULTS: A total of 1204 DEGs were identified between PPS and control. Gene ontology revealed extracellular matrix (ECM) and cell adhesion, and pathway analysis revealed fatty acid, p-53, hypoxia and inflammation. Eleven key regulator genes of PPS including growth factors (IGF1, TGFB2, TGFB3), transcription factors (HIF1A, JUNB, SMAD3), and transmembrane receptors (FGFR1, TNFRSF1A, TYROBP) were also identified. MAIN LIMITATIONS: The use of clinical history of PPS, in the absence of other criteria, may have led to misidentification of some cases as PPS. CONCLUSIONS: Transcriptomic analysis indicated that changes in ECM and cell adhesion were important factors in equine PPS. Key predicted upstream events include genes associated with hypoxia, inflammation and growth factors related to the pathogenesis of equine PPS.

Renal Riddles Unveiled: Decoding Homogeneous Kidney Enlargement in Multiple Myeloma.

Renal plasmacytoma is a rare extramedullary manifestation of plasma cell neoplasms (PCN). We present the case of a 62-year-old male with a history of relapsed refractory multiple myeloma (MM) who developed secondary renal plasmacytoma after an eight-year remission period. Radiological findings on plain CT raised concern for the most common renal malignancy, i.e. renal cell carcinoma (RCC), while further imagining evaluation with MRI suggested renal lymphoma, highlighting the diagnostic challenge of renal plasmacytoma on imagining. A renal mass biopsy confirmed a kappa-restricted plasma cell tumor, emphasizing the need for accurate differentiation between renal plasmacytoma and other renal malignancies to guide appropriate treatment strategies. Increased awareness of such cases can lead to timely recognition and tailored management for this rare entity.

Postcolonial control of Fiji soccer and the return of subjugated knowledges: From the 1970s to the 2010s.

The primary aim of this article is to use Foucault's idea of subjugated knowledges to search out areas and viewpoints within Fiji soccer which are suppressed by the governing authorities. To fulfill this aim, we explore and assess, via ethnographic research, the racial and ethnic aspects of Fiji soccer, from the 1970s to the 2010s, and how cultural hegemony facilitates continued Fiji Indian control and dominance within the sport. Next, and although we note the positive dimension of Fiji Football Association's 2014 Veterans' Dinner, we suggest that some ex-Ba players were apparently discriminated against by, puzzlingly, not being invited. The regulator was also unaware of, or insensitive to, ex-players' transportation needs as some were poor or invalid. We then look at the cases of Sweats Soccer Club (SSC) and Nadi Legends Football Club (NLFC) to show how, in the face of the regulator's indifference to the financial plight of an Indigenous village club (SSC), the ex-Nadi players set up instead a self-help organization (NLFC) to assist and encourage ex-players going through hard times. The latter was a cross-ethnic group/cross-class collaboration between ex-officials and ex-players and was largely outside the regulator's sphere of interest or intent.

Molecular epidemiology and characterization of Babesia bovis in cattle of Khyber Pakhtunkhwa province, Pakistan.

Babesiosis is a tick-borne disease found globally but most prominent in tropical and subtropical regions. It is responsible for huge mortality and morbidity, especially in developing countries like Pakistan. The current study was designed to determine the molecular epidemiology and characterization of Babesia bovis (B. bovis) infection in cattle populations of districts Mardan, Kohat and Swat of Khyber Pakhtunkhwa (KP) province of Pakistan. A total of 434 tick-infested animals were sampled. Blood samples were collected, processed and then examined initially by microscopy for the presence of Babesia and were later confirmed through PCR by targeting cytochrome b gene, and the PCR products were sequenced. Phylogenetic analysis of sequenced isolates of the current study showed close sequence similarity with the reported strain of China. A non-significant association (p > 0.05) was observed between the prevalence of infections and risk factors. The overall prevalence of infection in all three districts was 10.11%. In district Swat (12.61%), the prevalence was recorded as the highest for B. bovis infection followed by district Mardan (10.60%) and district Kohat (06.90%). The Friesian breed of cattle, females and adult animals were highly susceptible to B. bovis infection. The prevalence of infection was recorded highest during the summer season and lowest during the winter season. This study concludes that B. bovis infection is prevalent in three studied districts of KP province and the sequenced isolates of the current study showed close sequence similarity with the reported strain of China.

Imeglimin in type 2 diabetes.

Type 2 diabetes mellitus is a chronic disease most often characterized by increased glucose levels. When blood glucose levels are inadequately controlled or left untreated, the result is a variety of microvascular and macrovascular complications. To prevent these outcomes, many medications are available to manage type 2 diabetes mellitus and prevent disease progression. However, most of the medications available to date only target a few of the physiological defects caused by diabetes and may come with side effects that make adherence to the medication improbable. Imeglimin, a medication currently under investigation in the United States and approved in Japan, is a novel, first-in-its-class medication with a mechanism that is currently understood to target multiple pathways to provide glycemic control. This review aims to present and discuss the current clinical and scientific evidence pertaining to imeglimin.

SARS-CoV-2 Seroepidemiological Investigation in Jordan: Seroprevalence, Herd Immunity, and Vaccination Coverage. A Population-Based National Study.

Background: Population-based serosurveillance is a cornerstone to furthering our understanding of the COVID-19 pandemic at the community levels. In Jordan, four waves (phases) of seroprevalence epidemiological investigations were conducted using representative population-based national samples. This study aims to estimate the population-based seropositivity, herd immunity, and vaccination coverage at the fourth wave. Methods: Multistage sampling technique was implemented to recruit a nationally representative sample for the fourth wave of the seroprevalence investigation (June to August 2021). Electronically collected data utilized a questionnaire on background demographics, chronic diseases, and COVID-19 vaccination history. Also, blood samples were collected to detect the presence of total Anti-SARS-CoV-2 IgM and IgG using Wantai/ELISA assays. Prevalence estimates were presented using percentage and 95% Confidence Intervals (C.I.). Results: There were 8821 participants included in this study, with a mean age of 31.3 years, and 61.7% were females. COVID-19 national seroprevalence and vaccination coverage estimates were 74.1% (95% C.I.: 73.1-74.9%) and 38.4% (95% C.I.: 37.1-39.6%), respectively. Among children, seroprevalence estimates were similar to unvaccinated adults. Among COVID-19 adults, 57.2% were vaccinated. Among vaccinated participants, 91.5% were seropositive, while among unvaccinated, 63.2% were seropositive. By age group, seroprevalence ranged between 53.0% and 86.9%. Seroprevalence estimates were significantly different by gender, vaccination status and dose, and residence. Conclusion: The reported interplay between seropositivity and vaccination coverage estimate seems insufficient to provide herd immunity levels to combat new variants of SARS-CoV-2. Children and healthcare workers seem to be an epidemiologically influential group in spreading COVID-19. As the globe is still grappling with SARS-CoV-2 infection, national seroepidemiological evidence from Jordan calls for more focus on vaccination coverage, especially among epidemiologically vulnerable groups, to optimize herd immunity.

Importance of Antioxidant Supplementation during In Vitro Maturation of Mammalian Oocytes.

The in vitro embryo production (IVEP) technique is widely used in the field of reproductive biology. In vitro maturation (IVM) is the first and most critical step of IVEP, during which, the oocyte is matured in an artificial maturation medium under strict laboratory conditions. Despite all of the progress in the field of IVEP, the quality of in vitro matured oocytes remains inferior to that of those matured in vivo. The accumulation of substantial amounts of reactive oxygen species (ROS) within oocytes during IVM has been regarded as one of the main factors altering oocyte quality. One of the most promising approaches to overcome ROS accumulation within oocytes is the supplementation of oocyte IVM medium with antioxidants. In this article, we discuss recent advancements depicting the adverse effects of ROS on mammalian oocytes. We also discuss the potential use of antioxidants and their effect on both oocyte quality and IVM rate.

The Perceptions of Non-native Medical Students Towards Language Barrier on Clinical Teaching and Learning: a Qualitative Study from Saudi Arabia.

Background: Patient-doctor communication is essential for achieving the best healthcare quality for the patients. Saudi Arabia hosts a variety of healthcare providers from diverse cultures and languages, making language barriers distinctive towards effective communication for a predominantly Arab population. There is limited research on the challenges associated with language barriers among non-native medical students. The current qualitative study aims to explore the perceptions and experiences of non-native medical students during clinical encounters with Arabic speaking patient population at a private university in Riyadh, Saudi Arabia. Methods: This is a qualitative case study employing non-native medical students in clinical years to explore their perceptions and experiences towards language barriers. Participants attended four focus group discussions, following a brief regarding the concept of the challenges that language barriers pose. All interviews were recorded and transcribed verbatim. A thematic framework analysis was employed to analyze the data. Results: Twenty-two non-native medical students participated in the study. We identified four broad themes constituting problems in patient interaction, development of clinical skills, managing and overcoming language barriers, and student recommendations to overcome language barrier. Participants suggested improvements in available Arabic language courses and the introduction of a professional skills course in Arabic for non-native students. Conclusion: Non-Native medical students perceived language barriers as an obstacle to a meaningful clinical experience. They identified implications for clinical learning environment, professionalism, empathy, and patient care. Recommendations for advanced occupation-related Arabic language courses to facilitate doctor-patient interactions were made to improve patient-student interactions between native patients and non-native medical students.
