Article Synopsis
  • The study aimed to assess the choroidal vascular parameters in keratoconus (KC) patients and their relationship to eye topography.
  • Researchers analyzed 90 KC patients grouped by severity and compared them to 29 patients without KC, focusing on choroidal microvascular density and vascularity indices.
  • Results indicated a decrease in specific retinal nerve fiber thickness and choroidal vascularity in advanced KC patients, along with a weak negative correlation between choroidal vascularity and keratometry measurements.

Background: To examine the prognostic relevance of pan-immune-inflammation value (PIV) in locally advanced nasopharyngeal carcinomas (LA-NPC) patients treated with concurrent chemoradiotherapy (CCRT) definitively.

Methods: We used receiver operating characteristic (ROC) curve analysis to determine an optimal PIV cutoff that could effectively divide the patient cohort into two distinct groups based on distant metastasis-free (DMFS) and overall survival (OS) results. For this purpose, receiver operating characteristic (ROC) curve analysis was employed.

Article Synopsis
  • - Perioperative complications after classic Whipple surgery occur at a rate of about 40%, with delayed gastric emptying and pancreatic fistula being common, while gastrojejunostomy (GJ) leakage is rare.
  • - A case report focused on a 71-year-old male who developed a GJ leak post-surgery, highlighting the use of vacuum therapy and endoscopic intervention to manage the leak, resulting in successful closure with titanium clips.
  • - The literature indicates GJ leakage occurs in 0.54% of Whipple surgeries, with an average duration of symptoms from 4 to 34 days; this case marks the first documentation of endoscopic treatment for such leaks.

  • Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder that causes frequent bleeding in various organs, and diagnosing it can be challenging; researchers investigated exosomes (tiny vesicles) as potential biomarkers for HHT.
  • The study involved analyzing exosomes isolated from the blood of 20 HHT patients and 17 healthy donors, focusing on their protein composition and functional effects on human cells; specific proteins like Thrombospondin-1 were found to be significantly higher in HHT patients' exosomes.
  • Findings suggest that exosomal proteins, particularly Thrombospondin-1 and soluble Endoglin (sENG), could serve as biomarkers for HHT, offering a promising new

Sacubitril/Valsartan in Pediatric Heart Failure (PANORAMA-HF): A Randomized, Multicenter, Double-Blind Trial.

Circulation

November 2024

M3C-Necker, Congenital and Paediatric Cardiology Department, Hospital Necker-Enfants Malades, University of Paris Cité, France (D.B.).

Background: Sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), is an established treatment for heart failure (HF) with reduced left ventricular ejection fraction. It has not been rigorously compared with angiotensin-converting enzyme inhibitors in children. PANORAMA-HF (Prospective Trial to Assess the Angiotensin Receptor Blocker Neprilysin Inhibitor LCZ696 Versus Angiotensin-Converting Enzyme Inhibitor for the Medical Treatment of Pediatric HF) is a randomized, double-blind trial that evaluated the pharmacokinetics and pharmacodynamics (PK/PD), safety, and efficacy of sacubitril/valsartan versus enalapril in children 1 month to <18 years of age with HF attributable to systemic left ventricular systolic dysfunction (LVSD).

Introduction: The primary objective of this study was to evaluate the impact of vaginal uterosacral plication on urge symptoms and quality of life in a cohort of patients with uterosacral ligament insufficiency and urge symptoms.

Methods: A total of 40 female patients were included in the study, and their posterior fornix was supported with gauze to simulate the surgical procedure. Uterosacral plication was applied to patients who experienced a decrease in urinary incontinence, nocturia, a sense of urgency, and a decrease in urge urinary incontinence symptoms or complete recovery.

Article Synopsis
  • Mucosal melanomas, particularly in the oral and sinonasal regions, present diagnostic challenges due to their varied characteristics and differentiation patterns, including neuroendocrine features.
  • A study of 18 cases revealed that 72.2% displayed neuroendocrine differentiation, suggesting it is a common feature in these types of melanoma.
  • The research highlights the importance of recognizing neuroendocrine markers (like synaptophysin, chromogranin, CD56, and INSM-1) in preventing misdiagnoses in malignant melanomas.
