Background: Familial chylomicronemia syndrome (FCS) is diagnosed by genetic or non-genetic criteria.

Objective: To assess responses to treatment of apolipoprotein (apo)C-III, triglycerides, and pancreatitis events in patients with FCS-based diagnostic methods.

Methods: APPROACH enrolled 66 patients with FCS randomized to volanesorsen or placebo for 12 months.

Article Synopsis
  • The study evaluated how different oat genotypes and Canadian growing environments affect the composition and physical traits of oats.
  • Significant variations in protein, starch, and amylose content were found based on genotype, environment, and their interactions over two growing years.
  • Analysis revealed that certain genotypes, like CDC Morrison, were more sensitive to environmental changes, while insights gained could help breeders enhance oat quality for better end products.

  • The study aimed to analyze the genome of Achromobacter genogroup 20 and identify resistance determinants related to antibiotic resistance.
  • Isolate 413638 was classified as Achromobacter genogroup 20 ST365, demonstrating significant resistance to multiple antibiotics and possessing several resistance-related genetic elements, including a newly identified OXA-type β-lactamase.
  • The findings suggest that the resistance markers identified could explain the antibiotic resistance profile of Achromobacter genogroup 20 ST365, with the new OXA variant potentially serving as a useful marker for further species identification.

The canned motor pump has a unique design where the motor rotor and pump impeller are mounted on the same shaft, requiring careful balancing of axial and radial forces to ensure reliable operation. The use of a canned motor pump with a floating impeller system helps to balance the axial forces of the impeller, this balance ensures that the impeller is not subjected to excessive axial forces which can lead to premature wear or failure. The purpose of this study is to investigate the axial force on the canned motor pump when overheating occurs due to an operational fault in the distillation column.

Solitary fibrous tumors (SFTs) are a rare type of soft tissue tumor first identified as arising from pleura and usually arising in the thoracic cavity. The incidence of SFTs arising in the head and neck region is much lower, accounting for about 7% of SFT cases. Involvement of the larynx specifically is exceedingly rare and can have inconspicuous presentations, making them challenging to diagnose.

Good relationships between families and schools make a difference to children's learning - and the same goes for autistic children. But parents of autistic children often find it very stressful interacting with teachers and school staff. In this study, we focused on autistic parents of autistic children.

In recent years, the number of Doctor of Osteopathic Medicine (DO) residents entering general surgery has increased. As DOs continue to solidify their role within the surgical domain, understanding their distribution, preferences, and the dynamics of their integration into residency programs becomes crucial for general surgery applicants. Publicly available data were gathered for each DO general surgery resident from residency programs across the nation, including details such as post-graduate year, degrees held, and residency program location.

Introduction: The neurosurgery residency match has grown increasingly competitive, especially for osteopathic (DO) medical students, amidst the transition to a single accreditation system in 2020. This shift required former American Osteopathic Association (AOA) programs to apply for Accreditation Council for Graduate Medical Education (ACGME) accreditation, leading to a notable reduction in programs with a history of accepting DO applicants. This study aims to explore both potential geographical trends in residency match among recent DO neurosurgical residents and in the number of DO neurosurgical residents pre- and post-ACGME merger.

Partial heart transplantation (PHT) has emerged as a new treatment strategy to correct unrepairable heart valve dysfunction in pediatric patients. PHT selectively replaces the dysfunctional components of the recipient's heart and spares the native ventricles. As a result, the transplant biology of PHTs differs from heart transplants.

Simulation experiences are valuable to the training of future successful surgeons. These experiences introduce trainees to operational concepts through hands-on engagement within a low-stress environment to promote skill, information retention, and increased competency for future success in real-life scenarios. The study aimed to develop a low-cost, reproducible surgical simulation for teaching aortic valve replacement using porcine models.

  • Plasma exchange (PLEX) is shown to improve survival rates in patients with rodenticidal hepatotoxicity, but the factors that predict treatment success remain unclear.
  • A study analyzed 200 patients over nearly a decade to identify predictors of survival, focusing on changes in MELD score, bilirubin levels, and INR after PLEX treatment.
  • Results indicated that a significant decline in MELD score during treatment was the strongest independent predictor of one-month survival without liver transplantation.

Extramedullary plasmacytomas without evidence of systemic illness make up less than 5% of all plasma cell neoplasms. The incidence of extramedullary plasmacytoma of the thyroid region is exceedingly rare. This report discusses the case of a 72-year-old male with extramedullary plasmacytoma of the thyroid.

Liver function abnormalities are noted in a minority of pregnancies with multiple causes for the same. A small proportion of these develop severe liver injury and progress to acute liver failure (ALF). There is a discrete set of etiology for ALF in pregnancy and comprehensive understanding will help in urgent evaluation.

Background: Reducing the levels of triglycerides and triglyceride-rich lipoproteins remains an unmet clinical need. Olezarsen is an antisense oligonucleotide targeting messenger RNA for apolipoprotein C-III (APOC3), a genetically validated target for triglyceride lowering.

Methods: In this phase 2b, randomized, controlled trial, we assigned adults either with moderate hypertriglyceridemia (triglyceride level, 150 to 499 mg per deciliter) and elevated cardiovascular risk or with severe hypertriglyceridemia (triglyceride level, ≥500 mg per deciliter) in a 1:1 ratio to either a 50-mg or 80-mg cohort.

  • Familial chylomicronemia syndrome is a genetic condition that causes high triglyceride levels and can result in severe pancreatitis, which may be treated with the medication olezarsen that lowers triglycerides by reducing apolipoprotein C-III production.
  • A phase 3 clinical trial was conducted with 66 patients randomly assigned to receive either olezarsen (80 mg or 50 mg) or a placebo, with the goal of measuring changes in triglyceride levels and the incidence of acute pancreatitis over 6 months.
  • Results showed that the 80 mg dose significantly reduced triglyceride levels compared to placebo, while the 50 mg dose did not show significant improvement; both olezarsen doses resulted in reduced

Atypical teratoid/rhabdoid tumors (AT/RTs) are embryological tumors of the central nervous system (CNS). They are typically found in children, with rare presentations in adults. We describe the presentation of an AT/RT in the pituitary region of a 37-year-old female.

Heart valve replacement in children is an unsolved problem in congenital cardiac surgery because state-of-the-art heart valve implants do not grow. This leads to serial repeat operations to replace outgrown heart valve implants. Partial heart transplantation is a new transplant that helps alleviate this problem by delivering growing heart valve implants.
