Summary: The clinical and neuroimaging characteristics of rheumatoid meningitis (RM) in Chinese patients were analyzed retrospectively. Among 933 patients with rheumatoid arthritis (RA), six patients were identified with RM. Headache, hyperacute focal neurological deficits, and seizures were the most common symptoms. Meninges were affected in all patients and cerebral parenchyma in one patient. The lesions were generally located in the frontoparietal region. Immunotherapy, including tocilizumab, showed good response in most patients. RM in Chinese patients share similar characteristics and respond well to immunotherapy.

Summary: The importance of pro-inflammatory cytokines in the pathogenesis of rheumatoid arthritis and psoriatic arthritis has been supported by the effectiveness of their blockage in treatment. The JAK inhibitors show promise in modulating pain in patients with RA and PsA by affecting cytokine signaling through the JAK/STAT pathway.

Summary: This article reviews the immune mechanisms and pathological interactions between COVID-19 and RA, highlighting the similarities in immune inflammation. The potential mechanisms leading to cardiovascular complications and challenges in treating RA patients with COVID-19 are also discussed. Additionally, the use of antirheumatic drugs as potential treatment options for COVID-19 is explored, given the similar proinflammatory cytokines induced in both diseases.

Summary: The study showed that QLY granules have significant therapeutic effects on adjuvant arthritis rats, which may be associated with downregulating the CXCL12/CXCR4-NF-kappa B signaling pathway. Further research on the use of QLY granules as a potential treatment for rheumatoid arthritis is warranted.

Summary: Genistein, a natural isoflavone, exhibits various biological effects and has been investigated for its potential therapeutic benefits in bone and cartilage diseases. It shows estrogen-like activity in protecting against osteoporosis and osteoarthritis, and also acts as an inhibitor of tyrosine kinase involved in pathological development of these diseases. Multiple signaling pathways are involved in its regulatory activity, but the molecular mechanisms are not fully understood yet.

Summary: This study identified rare coding variants in JIA patients using RNA-seq data, including some reported causal variants. These variants were partially replicated in polyarticular patients and shared common variants with genes associated with autoimmune diseases. Genes related to immune pathways were enriched for rare coding variants and differentially expressed genes.

Summary: Methotrexate is associated with rare bone lesions that are often misdiagnosed as osteoporotic fractures. Early diagnosis is crucial for treatment and prevention of further osteopathology. This case highlights the importance of raising awareness and taking appropriate therapeutic measures, including discontinuing methotrexate.

Summary: Rheumatoid arthritis (RA) is an example of a disease with circadian fluctuations in severity. RA patients experience stiffness, pain, and swelling in the morning, which becomes less severe in the afternoon. This is due to higher levels of pro-inflammatory hormones and cytokines in the morning and insufficient anti-inflammatory cortisol levels.

Summary: Six genes associated with resistance to drugs used in CHOP-based protocol in canine lymphoma were identified in this study, and a novel scoring system to predict resistance to these drugs was proposed. This system may aid in selecting the most appropriate chemotherapy protocol for individual dogs with lymphoma.

Summary: This study describes the therapeutic efficacy of lapatinib as a first-line treatment for muscle-invasive urothelial carcinoma. The results show that dogs treated with lapatinib/piroxicam had a greater reduction in the size of the primary tumor and improved survival compared to those treated with piroxicam alone. Exploratory analyses also showed that HER2 overexpression was associated with response and survival in dogs treated with lapatinib.

Summary: Histiocytic sarcoma (HS) is a rare malignancy in dogs, with poor prognosis. This study investigated the involvement of apoptosis inhibitor of macrophage (AIM) in the development of HS in dogs. The expression of AIM in tumor tissue and serum AIM levels were evaluated, and the effects of AIM overexpression on HS cells were studied. The results suggest that elevated expression of AIM in tumor and serum could induce the progression of HS cells in dogs, and serum AIM levels may serve as a biomarker for HS.

Summary: In this study, a large-scale epidemiological study of autosomal dominant polycystic kidney disease (ADPKD) in cats was conducted in Japan. The conventional PKD1 variant was found to be prevalent in Scottish Fold, Persian, and Exotic Shorthair breeds. Additionally, four new variants in exon 15 of the PKD1 gene associated with cystic kidneys were identified. These findings have important implications for the pathogenesis of ADPKD in cats.

Summary: Urinary incontinence is a common issue in dogs, with Urethral sphincter mechanism incompetence (USMI) being a frequent cause. Traditional estrogen therapy for spayed female dogs with USMI may have limited efficacy and potential side effects, while testosterone treatment has shown promising results in castrated male dogs. This study retrospectively evaluated the use of methyltestosterone in spayed female dogs with USMI, showing that it had good or excellent responses in the majority of cases and could be considered as an alternative treatment option.
