Objectives: To prospectively evaluate the effect of guselkumab through 48 weeks across various clinical outcomes in subgroups of patients with psoriatic arthritis (PsA) and inadequate response to tumour necrosis factor inhibitors (TNFi-IR) from the phase 3b COSMOS trial. Subgroups were defined by baseline demographics, disease characteristics and prior/ongoing therapies.

Methods: Patients with active PsA (tender joint count (TJC) and swollen joint count (SJC) both ≥3) and TNFi-IR were randomised 2:1 to receive guselkumab 100 mg at week 0, week 4, then every 8 weeks through week 44 or to placebo with cross-over to guselkumab 100 mg at week 16 (early escape) or week 24 (planned).

Article Synopsis
  • The study aimed to assess the effectiveness of guselkumab, an antibody targeting interleukin-23p19, in treating patients with active psoriatic arthritis (PsA) who didn't respond adequately to 1-2 tumor necrosis factor inhibitors.
  • In the Phase IIIb COSMOS trial, 285 adults were randomly assigned to receive either guselkumab or a placebo, with results showing significant improvements in disease activity as measured by various composite indices, particularly at Week 24.
  • By Week 48, higher rates of low disease activity and remission were observed in patients taking guselkumab compared to those on placebo, indicating that guselkumab is effective even after previous treatment failures with

Introduction: There are limited data on the use of advanced therapies to treat psoriatic arthritis (PsA) in Russia. Guselkumab, an interleukin (IL)-23p19-subunit inhibitor, demonstrated efficacy in patients with PsA in the phase 3 DISCOVER-1 and -2, and COSMOS trials. This analysis evaluated the efficacy and safety of guselkumab in patients with PsA in Russia.

This study utilized to produce selenium nanoparticles (Se-NPs) in an environmentally friendly and ecologically sustainable manner, targeting several medicinal applications. These biosynthesized Se-NPs were meticulously characterized using X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, transmission electron microscope (TEM), and UV-visible spectroscopy (UV), revealing their spherical shape and size ranging between 28 and 78 nm. We conducted further testing of Se-NPs to evaluate their potential for biological applications, including antiviral, anticancer, antibacterial, antioxidant, and antibiofilm activities.

The process of creating a series of 3-amino-1-aryl-8-methoxy-1H-benzo[f]chromene-2-carbonitriles (4a-q) involved reacting 6-methoxynaphthalen-2-ol (1), the appropriate aromatic aldehydes (2a-q), and malononitrile (3) in an absolute ethanol/piperidine solution under Ultrasonic irradiation. However, the attempt to create 3-amino-1-aryl-1H-benzo[f]chromene-2,8-dicarbonitrile (6a, d, e) was unsuccessful when 6-cyanonaphthalen-2-ol (5) was stirred at room temperature, reflux, Microwave irradiation, or Ultrasonic irradiation. In addition, the target molecules were screened against Staphylococcus aureus (MRSA), Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Escherichia coli and Klebsiella pneumonia, as well as a panel of three human cancer cells lines such as MCF-7, HCT-116, HepG-2 and two normal cell lines HFL-1 and WI-38.

Antimicrobial resistance is one of the largest medical challenges because of the rising frequency of opportunistic human microbial infections across the globe. This study aimed to extract chitosan from the exoskeletons of dead bees and load it with bee venom (commercially available as Apitoxin [Api]). Then, the ionotropic gelation method would be used to form nanoparticles that could be a novel drug-delivery system that might eradicate eight common human pathogens (i.

Background: One of the current challenges is to secure wheat crop production to meet the increasing global food demand and to face the increase in its purchasing power. Therefore, the current study aimed to exploit a new synthesized nanocomposite to enhance wheat growth under both normal and drought regime. The effectiveness of this nanocomposite in improving the microbiological quality of irrigation water and inhibiting the snail's growth was also assessed.

In this study, we investigate the interactions of a hybrid nanofluid on a curved surface that is being stretched. The magnetic field is perpendicular to the flow and interacts with a mixture of molybdenum disulfide and argentum nanoparticles suspended in pure water, forming a hybrid nanomaterial. Our investigation considers heat transport analysis under different conditions, such as magnetohydrodynamic, Darcy-Forchheimer porous medium flow, Joule heating, and a convective boundary condition.
