    Abstract Background: GNAO1
    Materials and methods: We recruited and retrospectively reviewed five patients from two families seen at King Faisal Specialist Hospital and Research Centre in Riyadh (KFSHRC).
    Results: All patients presented with severe neurodevelopmental disorder, followed by progressive dystonia and hyperkinetic movements. In addition, none of the patients had seizures which was consistent with NEDIM phenotype. The specific diagnosis was not clinically entertained and was only found on whole exome sequencing (WES), which identified two variants (c.724-8G > A & c.709G > A). Both variants were previously reported as pathogenic de novo in patients with NEDIM, and one was reported as parental gonadal mosaicism.
    Conclusion: We report these variants as additional variants in

    Abstract Objectives: To explore women's knowledge and attitudes regarding NIPT, its implications, the factors affecting their decision to undergo the test and actions taken following a positive result.
    Methods: In this descriptive study, women who were offered NIPT through the foetal maternal clinic, were asked to complete an anonymous questionnaire about NIPT. The questionnaire consisted of 29 statements and covered four areas: demographics, knowledge, attitudes and decision-making.
    Results: A total of 150 women who were offered NIPT participated in this study. The results showed that generally women had poor knowledge of critical aspects of NIPT. This included the conditions tested for, the implications of the test and its limitations. Over 90% of women were in favour of NIPT and it being offered to all women of advanced maternal age while 66% of the tested women agreed to having confirmatory invasive testing in the case of a positive result.
    Conclusion: This study shows that the acceptance rate for NIPT is high despite incomplete understanding of the benefits and limitations of the test. The study findings support the need for education regarding this test through dedicated genetic counselling sessions in order to ensure that an informed decision can be made.

    Abstract This systematic review and meta-analysis examine preventive operative techniques in high-risk patients undergoing surgery for hemodialysis access to mitigate the risk of Dialysis Access-Associated Steal Syndrome (DASS). Chronic kidney disease often leads to end-stage renal disease (ESRD), necessitating dialysis. Successful vascular access is crucial for efficient dialysis, but complications, such as DASS, pose significant challenges. DASS redirects arterial blood flow, affecting populations undergoing arteriovenous access surgery. This study aims to assess preventive strategies, including distal revascularization with interval ligation (DRIL) and extension techniques. A systematic search of PubMed, Cochrane Library, EMBASE, and Web of Science until 2022 identified 11 relevant studies. The inclusion criteria comprised non-pediatric hemodialysis patients reporting outcomes related to patency and complications. The data were analyzed using Review Manager 5.3.5 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen). Meta-analysis indicated a significant association between DASS and arteriovenous fistula (AVF) or arteriovenous graft (AVG) procedures. Radiocephalic AVF (RC-AVF) and distal endovascular AVF procedures were favored. Various interventions addressed venous narrowing, including simple plication and loop interposition. The Modified by Inserted Latex Link for Endovascular Repair (MILLER) technique, DRIL, Extension Technique, and Proximalization of Arterial Inflow (PAI) were assessed for arterial bypass graft and blood supply preservation. This study underscores the importance of individualized strategies in preventing DASS during hemodialysis access surgery. Prophylactic measures, such as the extension technique, show promise, while DRIL remains effective in treatment. Ongoing research is imperative for optimizing outcomes in this complex patient population.

    Abstract Background Pleural biopsy for histological confirmation is the standard diagnostic procedure for pleural diseases. Aim To identify the role of percutaneous ultrasound (US)-guided true-cut needle biopsy in patients with sheet-like pleural thickening. Patients and methods A prospective interventional simple controlled trial was conducted on 60 patients with computed tomographic evidence of pleural thickening. Percutaneous US-guided pleural biopsies using a true-cut needle were performed for pathological tissue characterization; complications were recorded. Results All patients were diagnosed, with only five (8%) patients found to have self-limiting pneumothorax, with no need for a chest tube. Fifty-three percent of patients had a histopathological diagnosis of mesothelioma, 14% had a histopathological result of adenocarcinoma, whereas 33% had chronic fibrosing pleuritis. Conclusion The US-guided procedure has a major advantage as it is being real time, rapid, available bedside, and well tolerated, and no serious complications were observed in good case selection and procedure.

    Abstract The mucopolysaccharidoses are a heterogeneous group of inherited lysosomal storage disorders, characterized by the accumulation of undegraded glycosaminoglycans in various organs, leading to tissue damage. Mucopolysaccharidoses include eight individual disorders (IS [Scheie syndrome], IH [Hurler syndrome], II, III, IV, VI, VII and IX). They have autosomal-recessive transmission with the exception of mucopolysaccharidosis II, which is X-linked. Each individual disorder has a wide spectrum of phenotypic variation, depending on the specific mutation, from very mild to very severe. The skeletal and central nervous systems are particularly affected. The typical clinical presentation includes organomegaly, dysostosis multiplex with short trunk dwarfism, mental retardation and developmental delay. In this article, we review the neuroimaging manifestations of the different types of mucopolysaccharidoses including the dysostosis multiplex of the skull and spine as well as the various central nervous system complications. These include white matter injury, enlargement of the perivascular spaces, hydrocephalus, brain atrophy, characteristic enlargement of the subarachnoid spaces as well as compressive myelopathy. The correlation between several of the neuroimaging features and disease severity remains controversial, without well-established imaging biomarkers at this time. Imaging has, however, a crucial role in monitoring disease progression, in particular craniocervical junction stenosis, cord compression and hydrocephalus, because this allows for timely intervention before permanent damage occurs.

    Abstract In hyper-arid and arid zones, management of crop water requirements is considered a vital component for sustaining crop production. The efficiency of the irrigation method and the application of many kinds of organic matter are practices that should be followed in Egypt to maximize the use of irrigation water. Two field experiments were conducted during the two successive winter seasons of 2020/2021 and 2021/2022 to study the effect of drip irrigation systems and of several types of compost on yield and yield attributes of four cultivars of wheat in newly reclaimed sandy soils. Studied factors were irrigation levels based on the amount of water evapotranspiration (ET) (I₁, I₂, I₃) and the application of compost types (Com₁, Com₂ and Com₃) on four bread wheat cultivars. The parameters measured at each irrigation level were: heading date (day), plant height (cm²), number of spikes/m², number of grains/spike, 1000-grain weight (g), grain yield (t/fed.), Biological yield (kg/fed.) and harvest index (%). The farmyard manure (Com₃) gave the maximum values under irrigation shortages, reflected in producing the maximum values for traits measured in the 2020/2021 season as compared to (Com₁) or (Com₂) applications, which scored lower values for the traits for the different cultivars for wheat. The interaction (I₁, I₂) × Com₃ × (Mis₁, Mis₂) led to a significant increase during both seasons for all the yield and yield components studied. A drip irrigation system at the level of 80% of ET and application of Com₃ is recommended to optimize wheat productivity from the unit area. The savings in water irrigation would allow expansion of the cultivated area to decrease the gap between local crop production and local requirements.

    Abstract Monocarboxylate transporter 1 (MCT1) deficiency was first described in 2014 by Hasselt et al. as a novel genetic cause of recurrent ketoacidosis. Patients present in the first year of life with acute episodes of ketoacidosis triggered by fasting or infections. Patients with homozygous mutations are known to have a more severe phenotype with mild to moderate developmental delay and an increased prevalence of epilepsy. There is only one recent report of the neuroimaging findings of this disorder as reported by Al-Khawaga et al. (Front Pediatr. 7:299, 2019). We report the neuroimaging abnormalities in two siblings with similar clinical presentation of recurrent ketoacidosis, seizures, and developmental delay. Whole exome sequencing in the younger sibling confirmed a known pathogenic homozygous mutation in MCT1, also known as SLC16A1 gene. Brain MRI showed a similar very distinctive pattern of signal abnormality at the gray-white matter junction, basal ganglia, and thalami in both patients. Both siblings had agenesis of the corpus callosum. Knowledge of this pattern of brain involvement might contribute to an earlier diagnosis and timely management of this rare and under recognized disorder.

    Abstract Background: Patients with pathogenic sequence variants (PSVs) in BRCA1/BRCA2 are at high risk of developing ovarian cancer (OC). However, genetic testing for BRCA1/BRCA2 PSVs is still not a routine practice in the Middle East. With the lack of epidemiological studies in the region, we aim to describe the prevalence of BRCA1/BRCA2 PSVs in patients with OC across different countries in the Gulf region.
    Methods: The PREDICT study was an observational, prospective, epidemiological study, which consecutively recruited women with ovarian, primary peritoneal, and fallopian tube cancers from the following Gulf countries over the period from July 2017 to July 2019; United Arab Emirates (UAE), Kuwait, and Oman. The study was approved by the local ethics committee of participating centers. The BRCA1/BRCA2 PSVs were assessed by tissue genetic testing using next-generation sequencing (NGS).
    Results: A total of 105 women were included with a median age at diagnosis of 52 years (IQR 44.5 - 61.0). Nearly 11.4% of patients reported a family history of ovarian or breast cancer, while 4.7% of patients reported a family history of other cancers. Most of the patients (70.3%) had advanced disease (FIGO stage III/IV) at presentation. Eighty-eight patients (84%) were successfully tested for somatic BRCA1/BRCA2 PSVs. Fifteen patients (17%) were found to have PSVs in either BRCA1, BRCA2, or both genes; of them, 10 patients (11.2%) had BRCA1 somatic PSVs alone, eight patients (9.1%) had BRCA2 somatic PSVs, while three patients (2.9%) had both PSVs. Five patients with BRCA1/BRCA2 somatic PSVs had germline PSVs tests, and three of them tested positive. Concerning treatment, 87.6% of patients received perioperative chemotherapy and 6.6% as first-line palliative chemotherapy. Eighty-seven (82.9%) patients underwent debulking surgery, with no residual disease in 42.5% of patients.
    Conclusion: Our study showed that the prevalence of BRCA1/BRCA2 somatic PSVs in patients with OC is higher than the reported global figures (2-8%). However, more studies are warranted to further elucidate the prevalence of BRCA1/BRCA2 somatic and germline PSVs, as well as other relevant genetic alterations, to better understand their impact on OC patient outcomes in Gulf countries.
