Absence of functional acid-α-glucosidase (GAA) leads to early-onset Pompe disease with cardiorespiratory and neuromuscular failure. A novel Pompe rat model ( ) was used to test the hypothesis that neonatal gene therapy with adeno-associated virus serotype 9 (AAV9) restores cardiorespiratory neuromuscular function across the lifespan. Temporal vein administration of AAV9-DES-GAA or sham (saline) injection was done on post-natal day 1; rats were studied at 6-12 months old.

Rhino-orbital-cerebral mucormycosis (ROCM) is an opportunistic infection that has increased due to COVID-19 with the use of corticosteroids and diabetes being the most important predisposing factors. Orbital apex syndrome with central retinal artery occlusion secondary to mucormycosis is relatively rare. This case report highlights a case of a 62-year-old female with poorly controlled diabetes and a history of COVID-19 two weeks prior, who presented with acute right eye painful visual loss for three days associated with bulging of the right eye and drooping of the eyelid.

Objective: Psoriatic arthritis (PsA) is an inflammatory arthritis associated with psoriasis. Adding to studies focused on the role of T cells and macrophages, we sought to investigate the systemic activation of leukocytes in PsA.

Methods: We assessed the activation state of leukocyte populations, including polymorphonuclear neutrophils (PMNs) and monocyte/macrophages, in blood and synovial fluid (SF) by multicolour flow cytometry.

Article Synopsis
  • Small intestinal metastasis is very rare, with only 13 documented cases, typically presenting as intestinal obstruction, and patients with metastatic esophageal cancer face a very low survival rate.
  • A case study discusses a man in his 50s diagnosed with esophageal squamous cell carcinoma, who underwent aggressive treatment but subsequently experienced complications from small bowel metastasis.
  • Unfortunately, despite surgery, the patient only survived 3 months post-operation, highlighting the serious prognosis for esophageal cancer patients who develop small bowel metastasis and the need for early diagnosis and management.

Article Synopsis
  • The study looks at different types of cells in the infrapatellar fat pad (IFP) of the knee and how they change with knee osteoarthritis (KOA), gender, and obesity.
  • Researchers used advanced techniques to analyze over 80,000 cell nuclei from both healthy and KOA patients.
  • They discovered that certain cells behave differently based on these conditions, and they found important differences in the way fibroblast cells act in people with different body types.

  • The phase 3 DISCOVER-2 trial evaluated the effectiveness of guselkumab in treating psoriatic arthritis (PsA), focusing on individual patient outcomes rather than just group trends.
  • Post hoc analyses showed that a high percentage (93% to 99%) of patients maintained significant clinical improvements in joint disease at scheduled dosing visits and sustained these improvements over time.
  • Guselkumab demonstrated long-lasting benefits, with many patients continuing to experience improvements 100 weeks after achieving clinical milestones, indicating its potential as a robust treatment option for PsA.

Multifunctional colloidal microgels that exhibit stimuli-responsive behaviour and excellent biocompatibility have attracted particular attention for developing functional compartmentalized networks. Herein, a series of stimuli-responsive microgels (M0, M1, and M2) were designed through the copolymerization of di(ethylene glycol) methyl ether methacrylate (DEGMA) and methacrylic acid (MAA) monomers using hydroxy ethyl methacrylate-coupled azobenzene (HEMA-Az) and ethylene glycol dimetharylate (EGDMA) as crosslinkers. The behaviour of the microgels in response to temperature, pH, and light was thoroughly investigated using spectroscopic, microscopic, and light-scattering techniques.

Article Synopsis
  • - SARS-CoV-2 is still a major cause of death in North America, and this study examines how methotrexate and tumor necrosis factor inhibitors (TNFi) affect vaccine responses in patients with immune-mediated inflammatory diseases (IMID).
  • - Researchers collected and analyzed serum samples from 479 adults with conditions like inflammatory bowel disease (IBD) and rheumatoid arthritis (RA) across Canada to evaluate neutralization responses to COVID-19 vaccination.
  • - The results indicated that both methotrexate and TNFi independently reduced the ability to neutralize the virus, underscoring the need for careful vaccination strategies as COVID-19 remains widespread.

We were tasked by Canada's COVID-19 Immunity Task Force to describe severe adverse events (SAEs) associated with emergency department (ED) visits and/or hospitalizations in individuals with immune-mediated inflammatory diseases (IMIDs). At eight Canadian centres, data were collected from adults with rheumatoid arthritis (RA), axial spondyloarthritis (AxS), systemic lupus (SLE), psoriatic arthritis (PsA), and inflammatory bowel disease (IBD). We administered questionnaires, analyzing SAEs experienced within 31 days following SARS-CoV-2 vaccination.

Vision loss among the elderly is a major health-care problem. Vision impairment is associated with a decreased ability to perform activities of daily living and an increased risk for depression. Cataract is a common cause of vision impairment among the elderly, but surgery is often effective in restoring vision.

Article Synopsis
  • A 57-year-old woman developed paraneoplastic syndrome linked to primary lung cancer, starting with isolated right abducens palsy and worsening headaches and vision loss.
  • Medical examinations showed abnormal visual acuity, papilledema, and high cerebrospinal fluid pressure, while neuroimaging appeared normal.
  • Despite treatment with steroids and acetazolamide, her vision worsened, and she passed away six months after her diagnosis, highlighting the complexity and poor outcomes often associated with paraneoplastic syndromes.

Background: The psoriatic arthritis (PsA) Observational Study of Persistence of Treatment (PRO-SPIRIT) assesses effectiveness and persistence of real-world PsA treatments. Ixekizumab (IXE) is an interleukin (IL)-17A inhibitor (i) (IL-17Ai), approved for the treatment of adult PsA.

Methods: The aim of this predefined interim analysis was to report baseline characteristics along with early (3-month) descriptive and comparative real-world effectiveness in patients with PsA prescribed with advanced treatment including IL-17Ai; IXE or secukinumab (SEC), IL-12/23i, IL-23i, tumour necrosis factor (TNFi) or Janus kinase (JAKi).

At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual conference and trainee symposium, the status of psoriatic disease (PsD) biomarkers was discussed in a workshop. The significant heterogeneity of PsD causes disease management to be very challenging, but biomarkers can prove helpful in disease diagnosis, stratification, and precision medicine. Although a few potential biomarkers have been discovered, none have been fully validated.

Objectives: Anterior cruciate ligament (ACL) reconstruction after injury does not prevent post-traumatic osteoarthritis (PTOA). Circulating microRNA (miRNA) and metabolite changes emerging shortly after ACL injury and reconstruction remain insufficiently defined, potentially harbouring early cues contributing to PTOA evolution. Moreover, their differential expression between females and males also may influence PTOA's natural trajectory.

Objective: In the face of the ongoing circulation of SARS-CoV-2, the durability of neutralization post-COVID-19 vaccination in immune-mediated inflammatory disease (IMID) is a key issue, as are the effects of medications.

Methods: Adults (n = 112) with inflammatory bowel disease, psoriasis/psoriatic arthritis, rheumatoid arthritis, spondylarthritis, and systemic lupus were recruited from participating Canadian medical centers from 2021 to 2023. We focused on log-transformed neutralization (lentivirus methods) as a continuous outcome, with separate models for wild-type and Omicron strains BA.
