Introduction: Studies directly comparing the effectiveness of different biologics over long observation periods are lacking. As many treatment guidelines are formulated based on drug class, there is a particular need to compare drug classes rather than specific biologic agents.
Methods: This post hoc analysis compares the effectiveness and durability of biologics that target the interleukin (IL)-17 A ligands or the IL-17 receptor A (IL-17RA) relative to other approved drug classes in patients with moderate-to-severe plaque psoriasis, through 12 months in a real-world setting.

Despite the abundance of data concerning biologic treatments for patients with psoriasis, clinicians are often challenged with discerning the optimal treatment for each patient. To inform this selection, this study explored whether a patient's baseline characteristics or disease profile could predict the likelihood of achieving complete skin clearance with biologic treatment. Machine-learning and other statistical methods were applied to the substantial data collected from patients with moderate-to-severe psoriasis in the ongoing, international, prospective, observational Psoriasis Study of Health Outcomes (PSoHO).

The aim of this post-hoc analysis, using real world data from the Psoriasis Study of Health Outcomes (PSoHO), is to provide evidence if early intervention with biologics is associated with better treatment outcomes and if there is any difference among drug classes or individual biologics.
Materials And Methods: For this post-hoc analysis patients were categorised into two subgroups according to shorter (≤2 years) or longer (>2 years) disease duration.
Unlabelled: Metals are essential for all living organisms, but the type of metal and its concentration determines its action. Even low concentrations of metals may have toxic effects on organisms and therefore exhibit antimicrobial activities. In this study, we investigate the evolutionary adaptation processes of to metals and common genes for metal tolerance.

Purpose: Since skin is highly accessible, clinical photography is a useful tool to visually substantiate the real-world effectiveness outcomes of biologic-treated adults with moderate-to-severe psoriasis (PsO). We report the effectiveness and patient-reported outcomes at Week 12 between anti-interleukin (IL)-17A biologics and other biologics as well as ixekizumab and guselkumab in patients with available clinical photography at baseline and Week 12.
Patients And Methods: The Psoriasis Study of Health Outcomes (PSoHO) is an international, non-interventional, cohort study investigating the effectiveness of biologics in adults with moderate-to-severe psoriasis at Week 12.
This manuscript describes the development of the first diastereoselective intermolecular synthesis of alkyl ethers via reductive etherification of diverse ketones or aldehydes with alcohols. Key to this development was the use of low-temperature high-throughput experimentation (HTE) technologies that enabled rapid reaction optimizations and parallel synthesis. A broad scope of pharmaceutically relevant substrates was surveyed, which formed alkyl ethers effectively.

Methods: Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional, study comparing the effectiveness of anti-interleukin (IL)-17A biologics (ixekizumab and secukinumab) compared to other approved biologics and the pairwise comparative effectiveness of ixekizumab relative to five other individual biologics for patients with moderate-to-severe psoriasis.
Introduction: Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by heterogeneous clinical phenotypes and high symptom burden, especially through itch. Baricitinib (BARI), an oral Janus Kinase 1/2 inhibitor, is approved in Europe, Japan, and other countries, for treatment of adults with moderate-to-severe AD who are candidates for systemic therapy. This post hoc analysis of a Phase 3 topical corticosteroid (TCS) combination therapy trial (BREEZE-AD7) aims to characterize patients who might benefit most from BARI.

We present a protocol for the generation of a gene-deletion allelic-exchange plasmid and its recovery in for the purpose of constructing an in-frame gene deletion in Here, we present detailed methodologies for (i) the primer design (using the gene as our specific example); (ii) PCR amplification of the required gene fragments; (iii) preparation of the cloning vector (using the allelic-exchange vector pIMAY* as an example); (iv) the Gibson assembly cloning method; (v) introduction of the plasmid into ; (vi) confirmation of the plasmid insert in by colony PCR; and, finally, (vii) confirmation of the insert by sequencing. We also consider the long-term storage of the strains containing the desired plasmid.

Here we describe an allelic-exchange procedure for the construction of an unmarked gene deletion in the bacterium As a practical example, we outline the construction of a gene deletion in using the allelic-exchange plasmid pIMAY*. We first present the general principles of the allelic-exchange method, along with information on counterselectable markers. Furthermore, we summarize relevant cloning procedures, such as the splicing by overhang extension (SOE) polymerase chain reaction (PCR) and Gibson assembly methods, and we conclude by giving some general consideration to performing genetic modifications in .

This protocol is part of a series of methodologies for the construction of an in-frame gene deletion in strain RN4220. Having previously described how an allelic-exchange plasmid containing a desired gene deletion (in this case, pIMAY*-Δ) can be constructed and isolated from , we now present details of the next steps in this method-the preparation of electrocompetent cells and introduction of the mutant plasmid DNA into the cells by electroporation. Colonies containing the plasmid can then be selected on chloramphenicol plates at a low temperature permissive for plasmid replication.

Objective: To provide guidance to the clinical community on better understanding indirect comparison methods to help them to interpret their results by applying two quality standards to published indirect comparisons of systemic biologics for moderate to severe psoriasis.
Methods: A systematic literature review (SLR) of published indirect comparisons of biologics for the treatment of moderate to severe psoriasis in adults was conducted.
Objectives: To describe the results of a structured literature review of real-world outcomes with ixekizumab in patients with psoriasis (PsO) and/or psoriatic arthritis (PsA).
Methods: Literature databases, conference proceedings and additional sources were searched for relevant publications. Real-world studies of ≥25 ixekizumab-treated patients with PsO and/or PsA were included.
Introduction: In routine clinical care, important treatment outcomes among patients with moderate-to-severe plaque psoriasis (PsO) have been shown to vary according to patient demographics and disease characteristics. This study aimed to provide direct comparative effectiveness data at week 12 between anti-interleukin (IL)-17A biologics relative to other approved biologics for the treatment of PsO across seven clinically relevant patient subgroups in the real-world setting.
Methods: From the international, non-interventional Psoriasis Study of Health Outcomes (PSoHO), 1981 patients with moderate-to-severe PsO were grouped a priori according to seven clinically relevant demographic and disease variables with binary categories, which were sex (male or female), age (< 65 or ≥ 65 years), body mass index (≤ 30 or > 30 kg/m), race (White or Asian), PsO disease duration (< 15 or ≥ 15 years), psoriatic arthritis (PsA) comorbidity (present or absent), and prior biologic use (never or ≥ 1).
Atopic dermatitis is a chronic inflammatory skin disorder associated with a heterogeneous presentation and considerable disease burden. Exploring atopic dermatitis treatment patterns and patient benefits could improve disease management and patients' quality of life. This study aimed to describe current and previous atopic dermatitis treatment patterns and patient benefits from those treatments to inform disease management.
