Introduction: The objective of this study was to investigate the relationship of the IL-6 promoter variants G-597A, G-572C and G-174C (rs1800797, rs1800796 and rs1800795, respectively), which have been shown to affect both the transcription and secretion of IL-6, to symptomatic distal interphalangeal (DIP) osteoarthritis (OA).

Methods: A total of 535 women aged 45 to 63 years were included. Radiographs of both hands were taken and each DIP joint was evaluated (grade 0 to 4) for the presence of OA. Information on symptoms (pain, tenderness) in each joint was collected by using a self-administered questionnaire. Symptomatic DIP OA was defined by the presence of both radiographic findings of grade 2 or more and symptoms in at least two DIP joints, and symmetrical DIP OA by the presence of radiographic findings of grade 2 or more in at least one symmetrical pair of DIP joints. Common polymorphic loci in the IL-6 gene were amplified and the promoter haplotypes were reconstructed from genotype data with the PHASE program. Logistic regression analysis was used to examine the association between the IL-6 genotypes/diplotypes and the DIP OA outcome.

Results: The G alleles of two promoter single nucleotide polymorphisms (SNPs) G-597A and G-174C were more common among the subjects with symptomatic DIP OA than among those with no disease (P = 0.020 and 0.024, corrected for multiple testing). In addition, the carriage of at least one G allele in these positions increased the risk of disease (P = 0.006 and P = 0.008, respectively). Carrying a haplotype with the G allele in all three promoter SNPs increased the risk of symptomatic DIP OA more than fourfold (odds ratio (OR) 4.45, P = 0.001). Carriage of the G-G diplotype indicated an increased risk of both symmetrical DIP OA (OR 1.52, 95% confidence interval 1.01 to 2.28) and symptomatic DIP OA (OR 3.67, 95% confidence interval 1.50 to 9.00).

Conclusion: The present study showed that the presence of G alleles at common IL-6 polymorphic promoter loci was associated with the more severe DIP OA outcomes, symmetrical and symptomatic.

Background And Objectives: The benefit of mechanical thrombectomy (MT) in patients with acute ischemic stroke (AIS) with basilar artery occlusion (BAO) and a baseline National Institute of Health Stroke Scale (NIHSS) score <10 is unclear because this subpopulation has been substantially excluded from large clinical trials. The aim of our study was to determine whether MT ± IV thrombolysis (IVT) improves functional outcomes compared with IVT alone in patients with BAO and a NIHSS score <10.

Methods: We emulated a hypothetical trial including adult patients with BAO, a baseline NIHSS score <10, and prestroke modified Rankin scale (mRS) scores 0-2, comparing MT (±IVT) with IVT alone.

Introduction: Data on safety and efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke in older patients are limited and controversial, and people aged 80 or older were under-represented in randomized trials. Our aim was to assess EVT effect for ischemic stroke patients aged ⩾80 at a nationwide level.

Patients And Methods: The cohort included stroke patients undergoing EVT from the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS).

Article Synopsis
  • Paprika, a key greenhouse crop in Korea, saw a production of 82,042 tons in 2022 but faced increased disease issues in 2023, particularly interveinal chlorosis linked to whitefly infestations.
  • Observations from five farms indicated a 30-40% incidence of disease, likely due to the transmission of the tomato chlorosis virus (ToCV) by whiteflies, confirmed through electron microscopy and RT-PCR testing.
  • High-throughput sequencing of the virus confirmed the presence of ToCV and also yielded sequences related to bell pepper alphaendornavirus, indicating multiple viral threats to pepper crops.

Article Synopsis
  • - In 2018 and 2019, cowpeas in Tulare County, California were found to have serious root and stem problems that affected their growth, but only a small number of plants (less than 5%) were impacted.
  • - Scientists collected samples from these affected plants and discovered a harmful fungus called Fusarium solani, which can cause diseases in plants.
  • - They tested how this fungus could damage cowpea plants in a greenhouse and carefully measured the results to understand how it affects their growth.

Purpose Of Review: The most common four neurodegenerative atypical parkinsonian disorders (APDs) are progressive supranuclear palsy (PSP), multiple system atrophy (MSA), corticobasal syndrome (CBS), and dementia with Lewy bodies (DLB). Their formal diagnostic criteria often require subspecialty experience to implement as designed and all require excluding competing diagnoses without clearly specifying how to do that. Validated diagnostic criteria are not available at all for many of the other common APDs, including normal pressure hydrocephalus (NPH), vascular parkinsonism (VP), or drug-induced parkinsonism (DIP).
