Article Synopsis
  • A study assessed the 1-year treatment of nilotinib in patients with autosomal dominant spinocerebellar ataxia (ADSCA), focusing on treatment efficacy and safety.
  • Although the average ataxia severity, measured by the SARA score, did not significantly improve for the overall group, 62.5% of participants were considered 'responsive' based on score improvements.
  • Serum proteomic analysis identified specific proteins that may help predict which patients are likely to respond to nilotinib, suggesting potential pathways for improving treatment strategies for ADSCA.

For patients with non-small-cell lung cancer (NSCLC) tumors without currently targetable molecular alterations, standard-of-care treatment is immunotherapy with anti-PD-(L)1 checkpoint inhibitors, alone or with platinum-doublet therapy. However, not all patients derive durable benefit and resistance to immune checkpoint blockade is common. Understanding mechanisms of resistance-which can include defects in DNA damage response and repair pathways, alterations or functional mutations in STK11/LKB1, alterations in antigen-presentation pathways, and immunosuppressive cellular subsets within the tumor microenvironment-and developing effective therapies to overcome them, remains an unmet need.

  • Visible perivascular spaces (BGPVS) are linked to cerebral small vessel disease and may signal higher future stroke risk based on a large analysis of patient data.
  • The study analyzed 7,778 participants with recent ischemic stroke or transient ischemic attack (TIA), examining the relationship between BGPVS, CSOPVS, and various health factors.
  • Results indicated that a greater burden of BGPVS correlates with higher risks of ischemic stroke but not intracranial hemorrhage, while CSOPVS showed weaker associations overall.

Over the years, the hand, foot and mouth disease (HFMD) has sparked epidemics across many countries which mainly affected young children. While symptoms are usually mild, severe complications may arise, and some even lead to death. Such concerns, coupled with the lack of approved vaccines and antivirals to date, create an urgency in the identification of safe therapeutics against HFMD.

  • Remote ischemic conditioning (RIC) has been studied for its potential to lower blood pressure (BP) in patients with mild hypertension not on antihypertensive medications.
  • In a multicenter trial with 95 participants, the RIC group showed a significant reduction in 24-hour average systolic BP compared to a sham group after 4 weeks of treatment.
  • RIC was found to be safe, but further research is needed to determine its effects on broader clinical outcomes.

Article Synopsis
  • Researchers studied patients with certain types of strokes (IS or TIA) to find out how a brain condition called cortical superficial siderosis (cSS) affects their risk of having more strokes in the future.
  • They looked at data from a large group of patients and found that those with cSS had a higher chance of having more strokes than those without it.
  • Patients with cSS who took both types of blood-thinning medicines had an even higher risk of severe strokes and intracranial hemorrhage (bleeding in the brain).

Background: Recent evidence indicates that long-term visit-to-visit blood pressure variability (BPV) may be associated with risk of cardiovascular disease. We, therefore, aimed to determine the potential associations of long-term BPV from childhood to middle age with subclinical kidney damage (SKD) and albuminuria in adulthood.

Methods: Using data from the ongoing cohort of Hanzhong Adolescent Hypertension study, which recruited children and adolescents aged 6 to 18 years at baseline, we assessed BPV by SD and average real variability (ARV) for 30 years (6 visits).

Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide, however our understanding of cell specific mechanisms underlying COPD pathobiology remains incomplete. Here, we analyze single-cell RNA sequencing profiles of explanted lung tissue from subjects with advanced COPD or control lungs, and we validate findings using single-cell RNA sequencing of lungs from mice exposed to 10 months of cigarette smoke, RNA sequencing of isolated human alveolar epithelial cells, functional in vitro models, and in situ hybridization and immunostaining of human lung tissue samples. We identify a subpopulation of alveolar epithelial type II cells with transcriptional evidence for aberrant cellular metabolism and reduced cellular stress tolerance in COPD.

Nucleic acids are used in many therapeutic modalities, including gene therapy, but their ability to trigger host immune responses in vivo can lead to decreased safety and efficacy. In the case of adeno-associated viral (AAV) vectors, studies have shown that the genome of the vector activates Toll-like receptor 9 (TLR9), a pattern recognition receptor that senses foreign DNA. Here, we engineered AAV vectors to be intrinsically less immunogenic by incorporating short DNA oligonucleotides that antagonize TLR9 activation directly into the vector genome.
