Dieulafoy lesions are a rare cause of gastrointestinal bleeding, characterized by an enlarged submucosal blood vessel that bleeds without visible abnormalities. The diagnosis is typically made via endoscopy, and treatment usually involves endoscopic therapy. This case involves a 46-year-old female who presented with upper gastrointestinal bleeding due to a Dieulafoy's lesion, treated with band ligation and later embolization after the lesion was found to originate from the left phrenic artery.

Article Synopsis
  • The study examines the impact of adding zinc oxide (ZnO) and titanium dioxide (TiO) nanoparticles to denture base resin on its surface hardness and flexural strength during chewing and occlusal loading.
  • Five groups of acrylic resin samples were created, with one group being a control and the others containing different concentrations of nanoparticles, and their properties were tested using specific machinery.
  • Results showed that the modified denture resins had significantly improved properties, with the highest surface hardness from 1% TiO and the best flexural strength from 1% ZnO, indicating better durability compared to conventional resins.

Article Synopsis
  • The review examines how different methods for creating removable partial dentures (RPDs), both traditional and digital, impact the accuracy of fit and precision.
  • A thorough analysis of literature identified 8 key studies, revealing that fabrication techniques like resin milling and selective laser melting produce varying levels of fit accuracy, with resin milling using PEEK being the most precise.
  • Common assessment methods include silicone-based evaluations and digital superimposition, which are effective for measuring how well RPDs fit after fabrication.

Article Synopsis
  • - A 64-year-old man with tuberous sclerosis complex (TSC) experienced a serious bleed due to an angiomyolipoma in his kidney, which is a common and dangerous issue associated with TSC, especially in those with specific genetic mutations.
  • - His existing health problems, like high blood pressure and cholesterol, made his condition more complicated, requiring intensive treatment that included fluid resuscitation and emergency procedures to stop the bleeding.
  • - The case emphasizes the need for careful monitoring of TSC patients for potential hemorrhages, especially from larger angiomyolipomas, and stresses the benefits of a team-based approach in managing these patients for both immediate and long-term care.

This paper introduces a novel hybrid optimization algorithm, PDO-DE, which integrates the Prairie Dog Optimization (PDO) algorithm with the Differential Evolution (DE) strategy. This research aims to develop an algorithm that efficiently addresses complex optimization problems in engineering design and network intrusion detection systems. Our method enhances the PDO's search capabilities by incorporating the DE's principal mechanisms of mutation and crossover, facilitating improved solution exploration and exploitation.

Introduction: Autism is a neurodevelopmental condition that is increasing in prevalence worldwide. There has been an exponential increase in autism-related research since 2010, when the first Singapore Clinical Practice Guidelines (CPG) on autism was published. Understanding of autism has since evolved to adopt a lifespan approach beyond that of a childhood condition.

The availability and utilization of telehealth services have been rapidly increasing in the past decade, which paved the way for ophthalmological care to be offered more easily and conveniently. However, the proficiency of telehealth in the context of ophthalmical care still requires further studies to prove its effectiveness. This study examined the proficiency of general practitioners in a telemedicine platform in identifying red flag symptoms, suggestive of retinal detachment, and devising optimal management strategies.

  • - Triple-negative breast cancer (TNBC) is a major health issue globally, and while chemotherapy was the primary treatment, immunotherapy is showing potential, especially in patients with mismatch repair protein (MMRP) deficiency.
  • - A study analyzing TNBC patients from 2015 to 2021 found that 9.2% exhibited deficient MMR, with most showing loss of specific proteins like PMS2 and MLH1.
  • - Although patients with dMMR showed higher five-year survival rates, the overall survival difference compared to proficient MMR patients wasn't significant; dMMR status may help predict outcomes and target immunotherapy treatments.

The paper examines the dynamics of asymmetric thin shell wormholes that connect two distinct spacetimes using the cut and paste technique. The focus is on analyzing the linear stability of these wormholes by considering radial perturbations and utilizing the modified generalized Chaplygin gas equation of state. The specific case of an asymmetric wormhole connecting Schwarzschild-Rindler spacetime to Schwarzschild-Rindler-de Sitter space-time is analyzed using this formalism.

Background: Any manipulation of the surface of natural teeth may result in a variation of their colour. The fixed orthodontic treatment (FOT) is one such procedure which alters the enamel surface during the procedure.

Objective: To clinically evaluate the colour changes in teeth associated with comprehensive FOT (to compare the changes in test and control groups) and to determine the relationship of age and gender on enamel colour due to FOT by using an advanced spectrophotometer.

Background: Vinyl polyether silicone (VPES) is a novel impression biomaterial made of a combination of vinyl polysiloxane (VPS) and polyether (PE). Thus, it is significant to assess its properties and behaviour under varied disinfectant test conditions. This study aimed to assess the dimensional stability of novel VPES impression material after immersion in standard disinfectants for different time intervals.

Background: The therapeutic challenge of managing acute full-thickness burns is significantly ameliorated with the introduction of dermal regeneration templates (DRTs). However, an updated synthesis of evidence-based data on the efficacy and safety of different DRTs is required.

Methods: This systematic review and meta-analysis conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines aims to evaluate the role of various DRTs in comparison with split-thickness skin grafting in managing acute burn injuries after excision and debridement.

Introduction: Dietary habits in Saudi Arabia have been shifting toward the Western diet, which is high in fat, salt, and sugar, leading to a high obesity rate. Different dietary strategies such as the Ketogenic Diet (KD), Intermittent Fasting (IF), Gluten Free Diet (GFD), and Calorie Restriction Diet (CRD) have shown an influential role in weight loss. This study aimed to compare trending diets and correlate different types of diet with obesity and lifestyle among adults in Saudi Arabia.

The main aim of this paper is to investigate the effect of non-uniform heat generation and viscous dissipation on the boundary layer flow of a power-law nanofluid over a nonlinear stretching sheet. Within the thermal domain, the analysis considers both thermal radiation and variable thermal conductivity. Through the use of similarity transformations, the governing boundary layer equations are transformed into a system of ODEs.

The association between intraductal papillary mucinous neoplasms (IPMNs) and extra-pancreatic malignancies is controversial. This cross-sectional study compared esophagogastroduodenal findings in 340 IPMN patients to those of age- and gender-matched controls without known IPMNs who underwent esophagogastroduodenoscopies (EGDs) for similar clinical reasons. The presence of gastric and esophageal cancer, Barrett's esophagus, neuroendocrine tumors (NETs), gastrointestinal stromal tumors (GISTs), gastric adenomas, and ampullary tumors was assessed.
