Article Synopsis
  • Dietary lipids, including plant oils, have significant implications on heart health and diseases like cardiovascular issues, but there's limited research on specific oils like chufa oil, olive oil, and anhydrous milk fat (AMF) in relation to atherosclerosis in mice.
  • In a study with 4-week-old C57BL/6N male mice, those fed with AMF had the highest occurrence of gallstones (85.7%), while chufa oil resulted in the lowest gallstone formation (42.9%) and reduced serum cholesterol levels.
  • Despite differences in food intake, body weight remained unchanged across groups, and chufa oil demonstrated benefits for cholesterol metabolism without harmful nutritional effects, although gallstone formation was a common

  • Diffuse alveolar hemorrhage (DAH) is a severe and uncommon complication in systemic lupus erythematosus (SLE) patients, with early diagnosis and treatment critical for improving survival rates.
  • In a study from the RELESSER register, 37 out of 4024 SLE patients experienced DAH, with notable characteristics including a high prevalence of women and links to renal issues and thrombocytopenia.
  • Factors associated with higher mortality in DAH patients included smoking, prior lupus nephritis, infections, and the use of cyclophosphamide, with a mortality rate of 35.7% observed in the cohort.

Psoriatic disease (PsD) affects multiple clinical domains and causes a significant inflammatory burden in patients, requiring comprehensive evaluation and treatment. In recent years, new molecules such as JAK inhibitors (JAKinhibs) have been developed. These have very clear advantages: they act quickly, have a beneficial effect on pain, are well tolerated and the administration route is oral.

Article Synopsis
  • Toxoplasmosis is a widespread parasitic disease caused by an intracellular parasite, highlighting the need for new treatment options.
  • The study investigated the effects of wheat germ oil (WGO) and propolis on Swiss albino mice infected with toxoplasmosis, analyzing their impact on parasite load and associated organ damage.
  • Results indicated that both WGO and propolis reduced parasite load significantly, with the combination treatment showing the most effectiveness in restoring the tissues affected by the infection.

Introduction: Canine parvovirus-2 (CPV-2) is one of the most common infectious diseases in dogs characterized by severe gastroenteritis, vomiting, and bloody diarrhea. Little information is available about this topic in Egypt, particularly in the Delta region. This study reports the prevalence and molecular analysis of CPV-2 variants collected from El-Gharbia and Kafrelsheikh governorates in the Delta of Egypt.

Obesity-induced skeletal muscle (SKM) inflexibility is closely linked to mitochondrial dysfunction. The present study aimed to evaluate the effects of melatonin on the red vastus lateralis (RVL) muscle in obese rat models at the molecular and morphological levels. Five-week-old male Zücker diabetic fatty (ZDF) rats and their age-matched lean littermates (ZL) were orally treated either with melatonin (10 mg/kg body weight (BW)/24 h) (M-ZDF and M-ZL) or non-treated (control) (C-ZDF and C-ZL) for 12 weeks.

The incorporation of fermented camel milk with natural additives possesses numerous benefits for the treatment of various pathological and metabolic conditions. The present study investigated the impact of fortification of fermented camel milk with sage or mint leaves powder (1 and 1.5%, respectively) on glucose and insulin levels, lipid profile, and liver and kidney functions in alloxan-induced diabetic rats.

Article Synopsis
  • The study aimed to evaluate how the timing of anakinra administration during hospital admission affects patient outcomes (death or ICU admission) in those with severe COVID-19 pneumonia, and to explore a simplified scoring system for assessing risk.
  • A retrospective analysis was conducted on 312 patients treated with anakinra and corticosteroids, categorizing them based on when they received anakinra relative to their admission; results indicated that early treatment significantly improved recovery rates compared to late treatment.
  • The patient cohort had an average age of 67.4 years, with comorbidities like hypertension, and overall showed elevated inflammatory markers, with a significant portion experiencing improved clinical outcomes within 30 days, though 27.8% unfortunately still

Objective: To evaluate the effectiveness and safety of tocilizumab (TCZ) monotherapy in biologic-naïve patients with rheumatoid arthritis (RA) versus patients with previous biologic exposure in a real-world setting.

Materials And Methods: Non-controlled clinical-trial, 32-week prospective multicenter study including RA patients with moderate-severe disease activity starting TCZ in monotherapy who had a prior inadequate response or were intolerant to methotrexate (MTX). Effectiveness according to EULAR response evaluated at 24-week and safety at 32-weekwere assessed.

Objective: To assess the efficacy and safety of abatacept (ABA) in monotherapy (ABAMONO) vs combined ABA [ABA plus MTX (ABAMTX) or ABA plus non-MTX conventional synthetic DMARDs (csDMARDs) (ABANON-MTX)] in RA patients with interstitial lung disease (ILD) (RA-ILD).

Methods: This was a restrospective multicentre study of RA-ILD Caucasian patients treated with ABA. We analysed in the three groups (ABAMONO, ABAMTX, ABANON-MTX) the following outcome variables: (i) dyspnoea; (ii) forced vital capacity (FVC) and diffusion capacity of the lung for the carbon monoxide (DLCO); (iii) chest high-resolution CT (HRCT); (iv) DAS28-ESR; (v) CS-sparing effect; and (vi) ABA retention and side-effects.

Objective: To evaluate pain intensity, widespread pressure pain, central sensitization (CS), and catastrophizing between subjects with primary and secondary Raynaud's phenomenon (RP) and healthy controls and to compare the relationships between vascular impairment and pain perception.

Methods: A preliminary case-control study was performed with a total sample of 57 participants (37 with RP). Sociodemographic data, clinical/vascular data, and pain variables (pain intensity, pressure pain sensitivity, pain magnitude and threshold, CS, and catastrophizing) were registered.

Background: Biological therapies against tumor necrosis factor α have revolutionized the treatment of several inflammatory rheumatic diseases. However, 30% of responders will present a clinical failure after having controlled the disease for at least 6 months (secondary clinical failure). Biological therapies may induce an unwanted immune response, which may alter the bioavailability of the drug causing a loss of clinical response.
