Article Synopsis
  • The study investigates how different reasons for revision surgery in adult spinal deformity (ASD) patients affect their postoperative outcomes, revealing a high incidence of reoperations.
  • A sample of 891 ASD patients was analyzed retrospectively, categorizing their revisions by cause, and assessing complications, radiographic results, and disability metrics.
  • Findings suggest that different etiologies (mechanical, infection, wound, and SI pain) lead to varying outcomes, with mechanical issues showing less improvement over time compared to others.

In this study, a transient viscosity adjustment method using a coaxial nozzle was explored to fabricate nanofibers from non-spinnable -poly(hydroxyamide) (-PHA). Unlike conventional electrospinning methods that often require additives to induce fiber formation, this approach relies on a sheath-core configuration, introducing tetrahydrofuran (THF) to the sheath to temporarily adjust solution viscosity. The diffusion of THF into the core -PHA solution resulted in momentary solidification at the interface, promoting nanofiber formation without compromising polymer solubility.

Study Design: A prospective study.

Purpose: To diagnose scoliosis, a visit to the hospital for radiography is typically necessary. In such cases, children with scoliosis are exposed to radiation, which may place their health at risk.

Article Synopsis
  • Follicular B (FOB) and marginal zone B (MZB) cells are essential for immune responses, but MZB cells can worsen endotoxic shock by producing interleukin-6.
  • The study finds that the transcription factors capicua (CIC) and ataxin-1-like (ATXN1L) are crucial for the development of both FOB and MZB cells, with CIC deficiency reducing both populations while ATXN1L deficiency primarily impacts MZB cells.
  • CIC deficiency disrupts B cell receptor signaling in FOB cells, and both deficiencies impair Notch signaling in MZB cells, with increased ETV4 levels preventing the development of MZB cells; deleting E

Article Synopsis
  • Poor muscle health, indicated by the normalized total psoas area (NTPA), is linked to negative recovery outcomes in spinal deformity surgery, which is a gap in current research.
  • The study aims to explore how NTPA correlates with patient mobility and the incidence of adverse events (AEs) post-surgery by analyzing data from 279 patients over a nine-year period.
  • Results include assessing postoperative ambulation and complications like urinary issues and delayed healing, using data from MRI to establish cut-off values for NTPA related to patient recovery.

Article Synopsis
  • Gastroesophageal Reflux Disease (GERD) leads to stomach contents flowing back into the esophagus, which may also affect ear health through the Eustachian tube.
  • A study of over 669,000 South Korean patients found a strong link between GERD and the occurrence of tinnitus, suggesting that the ear issues could be related to reflux problems.
  • However, treating GERD with proton pump inhibitors did not significantly lower the chances of developing tinnitus in these patients.*

With the increasing volume of synthetic fiber waste, interest in plastic reuse technologies has grown. To address this issue, physical and chemical recycling techniques for polyamide, a major component of textile waste, have been developed. This study investigates the remelting and reforming properties of four types of pristine and recycled polyamide 6, focusing on how the microstructural arrangement of recycled polyamides affects polymer fiber formation.

Objective: Effective child abuse intervention requires understanding its prevalence. While obtaining a comprehensive national estimate of child abuse cases is challenging, sentinel injuries-minor yet unusual injuries like bruises or wounds in pre-cruising-age children-can provide an indicative measure. Using the National Emergency Department Information System (NEDIS) data, this study aimed to gauge the prevalence of sentinel injuries using diagnostic codes in children under 12 months who visited emergency centers in South Korea and to evaluate the extent of child abuse screening in these cases.

Background: Early diagnosis of Nonalcoholic steatohepatitis (NASH) is crucial to prevent its progression to hepatocellular carcinoma, but its gold standard diagnosis still requires invasive biopsy. Here, a new marker-based noninvasive chemical biopsy approach is introduced that uses urine-secreted tyrosine metabolites.

Methods: We first identified NASH-specific decrease in TAT expression, the first enzyme in the tyrosine degradation pathway (TDP), by employing exometabolome-transcriptome correlations, single-cell RNA -seq, and tissue staining on human NASH patient samples.

Article Synopsis
  • This study focuses on improving patient outcomes in radiotherapy for malignant tumors by collecting comprehensive multi-modal data generated during treatment, rather than looking at single time-points.
  • The data collected from multiple institutions underwent strict integrity checks and was analyzed using AI models, leading to a substantial dataset that includes over 30,000 imaging scans and metadata from 5,019 patients.
  • Results showed that the AI models effectively validated most of the data quality, achieving a high classification accuracy, which suggests that this structured dataset can significantly enhance future research in radiotherapy efficiency.

Background And Objectives: The spectrum of patients requiring adult spinal deformity (ASD) surgery is highly variable in baseline (BL) risk such as age, frailty, and deformity severity. Although improvements have been realized in ASD surgery over the past decade, it is unknown whether these carry over to high-risk patients. We aim to determine temporal differences in outcomes at 2 years after ASD surgery in patients stratified by BL risk.

Objective: The objective of this study was to identify baseline patient and surgical factors predictive of optimal outcomes in staged versus same-day combined-approach surgery.

Methods: Adult spinal deformity (ASD) patients with baseline and perioperative (by 6 weeks) data were stratified based on single-stage (same-day) or multistage (staged) surgery, excluding planned multiple hospitalizations. Means comparison analyses were used to assess baseline demographic, radiographic, and surgical differences between cohorts.

Purpose: To investigate the impact of the Global Alignment and Proportion (GAP) score components on patient outcomes in Adult Spine Deformity (ASD) surgery.

Methods: Patients included underwent assessment via the GAP score and its individual components: pelvic version (GAP PV), lumbar lordosis (GAP LL), lumbar distribution index (GAP LDI) and spinopelvic component (GAP SP). Multivariable analyses assessed the association between alignment in these components and clinical outcomes in ASD patients.

Inflammation is a vital immune defense mechanism regulated by Toll-like receptors (TLRs) and the nuclear factor-kappa B (NF-B) pathway. TANK-binding kinase 1 (TBK1) is central to immunity and inflammation and influences antiviral responses and cellular processes. However, the precise role of TBK1 in modulating the NF-B pathway through interactions with other proteins, such as spleen tyrosine kinase (Syk), remains poorly understood.

Striatal cholinergic interneurons (ChIs) provide acetylcholine tone to the striatum and govern motor functions. Nicotine withdrawal elicits physical symptoms that dysregulate motor behavior. Here, the role of striatal ChIs in physical nicotine withdrawal is investigated.

Lipid nanoparticles (LNPs) are widely recognized as crucial carriers of mRNA in therapeutic and vaccine development. The typical lipid composition of mRNA-LNP systems includes an ionizable lipid, a helper lipid, a polyethylene glycol (PEG)-lipid, and cholesterol. Concerns arise regarding cholesterol's susceptibility to oxidation, potentially leading to undesired immunological responses and toxicity.

Fine particulate matter (FPM) is a major component of air pollution and has emerged as a significant global health concern owing to its adverse health effects. Previous studies have investigated the correlation between bone health and FPM through cohort or review studies. However, the effects of FPM exposure on bone health are poorly understood.
