The U4 small nuclear RNA (snRNA) forms a duplex with the U6 snRNA and, together with U5 and ∼30 proteins, is part of the U4/U6.U5 tri-snRNP complex, located at the core of the major spliceosome. Recently, recurrent variants in the U4 RNA, transcribed from the gene, and in at least two other genes were discovered to cause neurodevelopmental disorder.

Methods: Microperimetry examinations of healthy eyes from five independent study groups and one previously available dataset were included (1137 tests from 531 eyes of 432 participants [223 women and 209 men]). Linear mixed models (LMMs) were fitted to the data to obtain interpretable hill-of-vision models.

Background: Pediatric dysphagia is a commonly encountered clinical problem, with primary cricopharyngeal achalasia being a rare etiology. Management options for this condition include observation, medical and surgical management. The goal of this review paper was to summarize the current literature on the topic with respect to patient presentation, diagnosis and surgical management options.

Purpose: This review was aimed to assess the outcome of available randomized clinical trials (RCTs) on the efficacy of platelet concentrates (PC) in dentine-pulp complex regeneration.
Background: The escalating prevalence of ESBL-producing Enterobacteriaceae in Qatar's pediatric population, especially in community-onset febrile urinary tract infections (FUTIs), necessitates a comprehensive investigation into this concerning trend.
Results: Over the course of one year, a total of 459 infants were diagnosed and subsequently treated for UTIs. Cases primarily occurred in infants aged over 60 days, predominantly non-Qatari females born from term pregnancies.
We sought to determine the diagnostic accuracy of radiomics features in predicting HPV status in oropharyngeal squamous cell carcinoma (SCC) compared to routine paraclinical measures used in clinical practice. Twenty-six articles were included in the systematic review, and thirteen were used for the meta-analysis. The overall sensitivity of the included studies was 0.

Objectives: The aim of the present study was to compare 2 different routes of ketamine administration - intranasal (IN) vs.
Objectives: Pulpotomy is the most commonly performed treatment for asymptomatic primary molars with exposed dental pulp. This study aimed to assess the clinical /radiographic success of diode laser pulpotomy with mineral trioxide aggregate (MTA), calcium hydroxide (CH), and calcium-enriched mixture (CEM) cement as pulp capping agents.
Methods: This split-mouth randomized clinical trial was conducted initially on 34 children aged 3-8 years but 4 patients left the study before the first follow-up visit and the study was accomplished and analyzed with 30 cases.
Introduction: The aim of this study was to describe the design and the participants' baseline characteristics of a prospective natural history study of geographic atrophy (GA) secondary to age-related macular degeneration.
Methods: The optical coherence tomography (OCT) and microperimetry biomarker evaluation in patients with GA (OMEGA) study was conducted at a tertiary referral center (ClinicalTrials.gov identifier: NCT05963646).
Objective: For patients presenting with acute ischemic stroke (AIS) caused by large vessel occlusions (LVO), mechanical thrombectomy (MT) is the treatment standard of care in eligible patients. Modified Thrombolysis in Cerebral Infarction (mTICI) grades of 2b, 2c, and 3 are all considered successful reperfusion; however, recent studies have shown achieving mTICI 2c/3 leads to better outcomes than mTICI 2b. This study aims to investigate whether any baseline preprocedural or periprocedural parameters are predictive of achieving mTICI 2c/3 in successfully recanalized LVO patients.

Various tests have been proposed to assist in the work-up of suspected NTMCL, with varying diagnostic utility. This systematic review investigates the sensitivity of the various diagnostic methods used in the work-up of pediatric NTMCL.

Lymph node metastases are associated with poor clinical outcomes in pancreatic ductal adenocarcinoma (PDAC). In preoperative imaging, conventional diagnostic modalities do not provide the desired accuracy in diagnosing lymph node metastasis. The current review aims to determine the pooled diagnostic profile of studies examining the role of radiomics features in detecting lymph node metastasis in PDAC.

It is unclear from which countries the IMGs are arriving and what visas are being used to accommodate them.
Materials And Methods: We sent a survey to 195 program directors (PD) in diagnostic radiology (DR) inquiring about the number and nationality of IMG residents in their program, their attitudes about IMG candidates, the performance of their IMG trainees, and the visas that are offered.

This study examines the patterns of faculty solicitations by open-access (OA) publishers in radiology. The purpose of the research is to determine the factors that predict the likelihood of receiving such solicitations. We recruited 6 faculty members from 7 subspecialties in radiology to collect emails from OA journals for 2 weeks.

This study examined the associations between psychiatric and pain comorbidities and the likelihood of undergoing sleep surgery.
Study Design: A retrospective cohort study of adults with OSA.
Objective: The interruption of vascular supply to the inner ear is one of several proposed etiologies of sudden sensorineural hearing loss (SSNHL). The increased presence of cardiovascular risk factors may predispose patients to SSNHL through this pathway. This systematic review and meta-analysis studies the presence of cardiovascular risk factors in patients diagnosed with SSNHL.

Background: To study the additive value of radiomics features to the BCLC staging system in clustering HCC patients.
Methods: A total of 266 patients with HCC were included in this retrospective study. All patients had undergone baseline MR imaging, and 95 radiomics features were extracted from 3D segmentations representative of lesions on the venous phase and apparent diffusion coefficient maps.
