The management of postamputation pain remains a significant clinical challenge, with existing therapeutic approaches often yielding inconsistent outcomes. Neuromodulation techniques, particularly peripheral nerve stimulation (PNS), have emerged as promising interventions. However, the evidence supporting their effectiveness in treating phantom limb pain (PLP) and residual limb pain (RLP) remains limited.

Comprehensive characterization of the transcriptional landscape in Alzheimer's disease (AD) brains.

Sci Adv

January 2025

Department of Biostatistics and Health Data Science, School of Medicine, Indiana University, Indianapolis, IN 46202, USA.

Alzheimer's disease (AD) is the leading dementia among the elderly with complex origins. Despite extensive investigation into the AD-associated protein-coding genes, the involvement of noncoding RNAs (ncRNAs) and posttranscriptional modification (PTM) in AD pathogenesis remains unclear. Here, we comprehensively characterized the landscape of ncRNAs and PTM events in 1460 samples across six brain regions sourced from the Mount Sinai/JJ Peters VA Medical Center Brain Bank Study and Mayo cohorts, encompassing 33,321 long ncRNAs, 92,897 enhancer RNAs, 53,763 alternative polyadenylation events, and 900,221 A-to-I RNA editing events.

While mostly de novo truncating variants in SCAF4 were recently identified in 18 individuals with variable neurodevelopmental phenotypes, knowledge on the molecular and clinical spectrum is still limited. We assembled data on 50 novel individuals with SCAF4 variants ascertained via GeneMatcher and personal communication. With detailed evaluation of clinical data, in silico predictions and structural modeling, we further characterized the molecular and clinical spectrum of the autosomal dominant SCAF4-associated neurodevelopmental disorder.

Article Synopsis
  • - Spinal cord stimulation (SCS) is a minimally invasive method used to treat severe neuropathic pain, but it's important to be aware of possible biologic complications during implantation.
  • - Although biologic complications like infection and nerve injury happen less often than device-related issues, they can have more serious effects on patients.
  • - Understanding these potential complications is essential for doctors to ensure patient safety and improve outcomes when using SCS for pain management.

Background: The relationship between inflammatory biomarkers (IB) and organ space surgical site infections (OS-SSIs) after emergency laparotomy (EL) is poorly understood.

Methods: Retrospective, single-center analysis of patients in the Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial who underwent EL and survived 48 ​h after admission was performed. IB levels of IL-6, IL-8, G-CSF, MCP-1, neutrophil to lymphocyte ratio, and platelet to lymphocyte ratio were analyzed.

  • - The study evaluates the effectiveness of the 5-minute Apgar score in predicting neonatal mortality specifically in infants with major birth defects, indicating its substantial predictive capability.
  • - Analyzing data from the Texas Birth Defect Registry, researchers found that low Apgar scores (less than 7) were strongly linked to higher mortality rates within the first 28 days of life, even among different defect categories and types of births (preterm and term).
  • - The findings suggest that the Apgar score can serve as a valuable tool for quick clinical assessments of newborns with birth defects, but further research is necessary to optimize its use in this group.

Ann Surg

November 2024

Department of Cardiothoracic and Vascular Surgery, Advanced Aortic Research Program at the University of Texas Health Science Center at Houston, McGovern Medical School, Houston, TX.

Objective: To compare target artery (TA) outcomes after fenestrated or branched endovascular aortic repair (FB-EVAR) versus open surgical repair (OSR) of thoracoabdominal aortic aneurysms (TAAAs).

Background: Few studies have compared TA outcomes after endovascular incorporation and open reconstruction.

Methods: Among consecutive patients who underwent elective OSR or FB-EVAR of TAAAs (2008-2020), we reviewed those who had postoperative imaging studies evaluating TA.

Unlabelled: This retrospective observational study using clinical data from two large hospitals in the Netherlands evaluated midterm outcomes of fenestrated endovascular aortic repair for juxtarenal abdominal aortic aneurysms (JAAAs), comparing supracoeliac with infracoeliac sealing. Supracoeliac sealing is considered advantageous due to a longer proximal sealing, but morbidity is usually higher. Supracoeliac proximal sealing was found to be safe and effective for treating JAAAs, with peri-operative and midterm outcomes comparable with infracoeliac proximal sealing.

External validation of the Epic sepsis predictive model in 2 county emergency departments.

JAMIA Open

December 2024

Department of Health Informatics and Data Science, Harris Health System, Houston, TX 77401, United States.

Article Synopsis
  • The study aimed to evaluate the effectiveness of the Epic Sepsis Predictive Model (ESPMv1) alert system in emergency departments by tracking its performance in identifying patients at risk for sepsis over the course of a year.
  • Out of nearly 146,000 patient encounters, the ESPMv1 alert was triggered in only 4.9% of cases, detecting sepsis in 2253 encounters while missing it in many others, leading to low sensitivity (14.7%) but high specificity (95.3%).
  • The findings suggest that the alert system offers minimal help to physicians in diagnosing sepsis, as most cases were treated without alert notifications, indicating the tool's limited diagnostic utility

McWilliams School of Biomedical Informatics at the University of Texas Health Science Center at Houston, Houston, TX 77030, USA; Institute for Stroke and Cerebrovascular Diseases, University of Texas Health Science Center at Houston, Houston, TX 77030, USA. Electronic address:

Acute stroke management involves rapid and accurate interpretation of CTA imaging data. However, generalizable models for multiple acute stroke tasks able to learn from unlabeled data do not exist. We propose a linear probed self-supervised contrastive learning utilizing 3D CTA images and the findings section of radiologists' reports for pretraining.

Article Synopsis
  • - The study analyzed the OXYGEN trial, which compared high levels of oxygen (80% FiO2) vs. lower levels (30% FiO2) for preventing infections in patients with specific types of fractures and aimed to see if using an "as-treated" approach changed the results compared to the "intention-to-treat" method.
  • - Conducted at 29 trauma centers, 1,231 patients with tibial plateau, tibial pilon, or calcaneus fractures were randomly assigned to either oxygen treatment; adherence was evaluated using two specific criteria based on the percentage of surgery time at different oxygen levels.
  • - Results showed no significant differences in primary and deep infection rates, but the treatment group had fewer

Article Synopsis
  • - The review examines how initial interfragmentary motion (IFM) affects fracture healing, noting its importance in orthopedic interventions for improving healing outcomes.
  • - A total of 4,972 studies were found, but only 15 studies involving 605 fractures were included, with most focusing on animal models, particularly involving the tibia, which showed positive healing effects with small to moderate IFM.
  • - Overall, the findings suggest that early micromovement is beneficial for fracture stiffness and healing, while larger IFM can result in bigger callus areas but may compromise callus quality and strength.
