    Abstract The quasinormal mode spectrum of black holes is unstable under small perturbation of the potential and has observational consequences in time signals. Such signals might be experimentally difficult to observe and probing this instability will be a technical challenge. Here, we investigate the spectral instability of time-independent data. This leads us to study the Regge poles (RPs), the counterparts to the quasinormal modes in the complex angular momentum plane. We present evidence that the RP spectrum is unstable but that not all overtones are affected equally by this instability. In addition, we reveal that behind this spectral instability lies an underlying structure. The RP spectrum is perturbed in such a way that one can still recover stable scattering quantities using the complex angular momentum approach. Overall, the study proposes a novel and complementary approach on the black hole spectral instability phenomena that allows us to reveal a surprising and unexpected mechanism at play that protects scattering quantities from the instability.

    Abstract In 2016, the Nottingham group detected the rotational superradiance effect. While this experiment demonstrated the robustness of the superradiance process, it still lacks a complete theoretical description due to the many effects at stage in the experiment. In this paper, we shine new light on this experiment by deriving an estimate of the reflection coefficient in the dispersive regime by means of a Wentzel-Kramers-Brillouin analysis. This estimate is used to evaluate the reflection coefficient spectrum of counter-rotating modes in the Nottingham experiment. Our finding suggests that the vortex flow in the superradiance experiment was not purely absorbing, contrary to the event horizon of a rotating black hole. While this result increases the gap between this experimental vortex flow and a rotating black hole, it is argued that it is in fact this gap that is the source of novel ideas. This article is part of a discussion meeting issue 'The next generation of analogue gravity experiments'.

    Abstract Atopic dermatitis (AD) is a common chronic relapsing inflammatory skin disease. The pathogenesis of AD is complex and still not fully understood. Despite recent therapeutic developments, the current therapeutic arsenal of AD remains limited and is associated with long-term efficacy and safety issues. Therefore, new topical therapies with different mechanisms of action are required to overcome the limitations of existing treatments. Difamilast is a phosphodiesterase 4 inhibitor currently in phase 3 studies. Difamilast shows antipruritic and anti-inflammatory properties and a rapid onset of action, with significant differences in some parameters from the vehicle within 1 week of treatment. Phase 2 and 3 clinical trials have shown that difamilast ointments are effective and well tolerated in adult and pediatric patients with AD, and are expected to be used for long-term AD treatment. In 2021, difamilast was the first phosphodiesterase 4inhibitor to acquire manufacturing and marketing approval in Japan for the treatment of adult and pediatric patients (2 years of age and older) with AD. This article is a narrative review of the current literature on difamilast in the management of AD.

    Abstract Purpose of review: This review aims to provide a summary of current knowledge on new topical and oral non-biological therapies recently approved for Atopic Dermatitis (AD) treatment.
    Recent findings: The immense research carried out in the last decade has focused on understanding the molecular basis underlying AD and has allowed the development of new targeted drugs. Despite several biologic therapies are approved or in development, other non-biologic targeted therapies (small molecules) have emerged, such as the Janus kinase (JAK) inhibitors baricitinib, upadacitinib and abrocitinib, expanding the range of therapeutic options. Based on recent available data from head-to-head comparisons and meta-analysis studies, JAK inhibitors showed a faster onset of action and slightly higher efficacy at 16 weeks compared with biologic agents. Concerning topical treatment, presently, corticosteroids and calcineurin inhibitors are the main therapeutic options, but are not recommended for long-term management due to potential safety issues. Currently, two topical JAK inhibitors (ruxolitinib and delgocitinib) and one phosphodiesterase 4 (PDE4) inhibitor (difamilast) are approved and have shown good efficacy results and a favorable safety profile.
    Summary: These new drugs (systemic and topical) are needed to increase the success of AD treatment, particularly for patients who do not or no longer respond to treatment.

    Abstract The introduction of biologic agents for the treatment of psoriasis has revolutionized the current treatment landscape, targeting cytokines in the interleukin (IL)-23/IL-17 pathway and demonstrating strong efficacy and safety profiles in clinical trials. These agents however are costly, are associated with a risk of immunogenicity, and require administration by intravenous or subcutaneous injection, limiting their use among patients. Oral therapies, specifically small molecule and microbiome therapeutics, have the potential to be more convenient and cost-effective agents for patients and have been a focus of development in recent years, with few targeted oral medications available for the disease. In this manuscript, we review pipeline oral therapies for psoriasis identified through a search of ClinicalTrials.gov (30 June 2022-1 October 2023). Available preclinical and clinical trial data on each therapeutic agent are discussed. Small molecules under development include tumor necrosis factor inhibitors, IL-23 inhibitors, IL-17 inhibitors, phosphodiesterase-4 inhibitors, Janus kinase inhibitors, A3 adenosine receptor agonists, and sphingosine-1-phosphate receptor 1 agonists, several of which are entering phase III trials. Oral microbials have also demonstrated success in early phase studies. As new oral therapies emerge for the treatment of psoriasis, real-world data and comparative trials are needed to better inform their use among patients.

    Abstract The management of psoriasis in individuals with human immunodeficiency virus (HIV) presents a unique challenge, marked by a more severe progression and limited efficacy of first- and second-line treatments. Although conventional systemic therapies might be considered, these agents are immunosuppressants, making their use challenging in people living with HIV (PLHIV). Biologic agents are frequently used in individuals with moderate-to-severe psoriasis, but their efficacy and safety data in PLHIV are very limited, as this patient group tends to be excluded from clinical trials. Risankizumab is a selective interleukin-23 (IL-23) inhibitor that has demonstrated a favourable safety profile and high efficacy in long-term studies and clinical practice. This current case report presents two clinical cases of PLHIV with plaque psoriasis who were effectively treated with the biologic agent risankizumab, with no reported safety issues. Although there are limited data on the use of biologics in PLHIV, this case series suggests that IL-23 inhibitors, namely risankizumab, might be a valuable therapeutic option for this population. Additional research and larger studies are needed to gain a more comprehensive understanding of the long-term safety and efficacy of IL-23 inhibitors in individuals affected by HIV.
