Camellia saponin modulates oleic acid/linoleic acid-induced lipogenesis in human sebocytes through lipophagy activation.

Background: Oily skin not only threatens people with aesthetic and hygienic discomfort but also confronts them with annoying skin problems. To explore new skin care ingredients from herbal or plant extracts and understand their underlying mechanism for sebum control would assist in the discovery of desirable sebosuppressive agents, though it is still a deserving and challenging task.

Aim: To explore the effect of Camellia saponin (CS) on modulating the lipogenesis of human sebocytes.

Tea (Camellia sinensis) Seed Saponins Act as Sebosuppression Agents via the AMPK/mTOR Pathway.

Background: Excessive lipogenesis of the skin triggers some dermatological concerns, such as enlarged pores, acne, and blackheads. Although topical drug treatments can offer temporary relief, their prolonged usage may lead to side effects of dryness, irritation, or allergic reactions. Consequently, the development of safer and efficacious ingredients in cosmetics for managing sebum overproduction represents a significant yet challenging endeavor.

Improved survival of advanced melanoma patients receiving immunotherapy with concomitant antithrombotic therapy - A multicenter study on 2419 patients from the prospective skin cancer registry ADOReg.

Background: Cancer immunotherapy has revolutionized melanoma treatment, but the high number of non-responders still emphasizes the need for improvement of therapy. One potential avenue for enhancing anti-tumor treatment is through the modulation of coagulation and platelet activity. Both have been found to play an important role in the tumor microenvironment, tumor growth and metastasis.

Apocrine Gland Damage and the Release of Specific Keratins in Early Stage Indicate the Crucial Involvement of Apocrine Glands in Hidradenitis Suppurativa.

The apocrine glands (AGs) are not considered to be primarily involved in hidradenitis suppurativa (HS). This study investigated the potential role of AGs in HS pathogenesis using immunohistochemistry and single-cell sequencing of nonlesional skin and early lesional skin (LS) from patients with HS (n = 12) and healthy controls (n = 8). AG cell destruction was more frequent, and AG size was significantly reduced in the nonlesional skin and LS.

Secukinumab efficacy in patients with hidradenitis suppurativa assessed by the International Hidradenitis Suppurativa Severity Score System (IHS4): A post hoc analysis of the SUNSHINE and SUNRISE trials.

Introduction: The International Hidradenitis Suppurativa Severity Score System (IHS4) is a validated tool that measures inflammatory lesions, including draining tunnels, in hidradenitis suppurativa (HS).

Objective: To evaluate secukinumab efficacy using IHS4 in patients with moderate to severe HS.

Methods: Data from the SUNSHINE and SUNRISE trials, which assessed subcutaneous secukinumab 300 mg every 2 (SECQ2W) and 4 (SECQ4W) weeks in adults with moderate to severe HS, were analyzed.

Demographic Data, Risk Factors, and Disease Burden of HS Patients in Lithuania at a Reference Center.

Background: Hidradenitis suppurativa (HS) diagnosis often faces a global delay of 7.2 years due to factors like lack of recognition, stigma, and socioeconomic barriers. Limited effective therapies and frequent exacerbations impact patients' quality of life, posing a significant burden on healthcare systems.

Short Version of the Quality of Life Relevance-Acne Questionnaire.

Introduction: The goal of the present study was to develop a short version (SV) of the Quality of Life Relevance-Acne (QOLRELEVANCE-ACNE) based on the identified most relevant items for acne patients.

Methods: Members of the international internet group for acne patients were asked to fill in the short prototype version of the QOLRELEVANCE-ACNE. Internal consistency was measured using Cronbach's alpha.

BAUSSS biomarker improves melanoma survival risk assessment.

Background: The American Joint Committee on Cancer (AJCC) method of staging melanoma is dated and inaccurate. It ignores important prognostic melanoma features, especially the patient's age. BAUSSS is more accurate in determining survival risk for primary cutaneous melanoma patients who have no clinical or imaging evidence of nodal or distant metastases.

Comorbidities, Clinical Presentation, Subtypes, and Treatment of HS Patients in Lithuania.

: Hidradenitis suppurativa (HS) is a persistent, recurring skin inflammatory condition linked to various comorbidities. Management involves antibiotics, hormone therapy, immune-modulating drugs, surgery, and treatment of comorbidities. The objectives of the study were to assess the comorbidities, clinical presentation subtypes, and applied treatment of patients with HS.

Unveiling the mechanism of photothermal therapy in acne man-agement: targeting sebaceous gland ferroptosis via umbilical cord mesenchymal stem cell membrane-encapsulated Au-Ag-PDA.

Background: Branched gold and silver nanoparticles coated with polydopamine (Au-Ag-PDA) demonstrate high photothermal conversion efficiency. Utilizing umbilical cord mesenchymal stem cell membranes (MSCM) as an effective drug delivery system, our preliminary studies investigated the suppression of sebum secretion in sebaceous glands using MSCM-coated Au-Ag-PDA nano-particles (Au-Ag-PDA@MSCM) combined with 808 nm laser irradiation, showing potential for dermatological applications in acne treatment.

Methods: This study employs proteomic analysis, complemented by subsequent techniques such as Western blotting (WB), small interfering RNA (siRNA), and transmission electron microscopy, to further investigate the differential mechanisms by which Au-Ag-PDA and Au-Ag-PDA@MSCM-mediated photothermal therapy (PTT) suppress sebum secretion.

Standardized Protocols for Clinical and Histopathological Characterization of Hidradenitis Suppurativa Tissue Specimens.

Methods for describing and reporting the clinical and histologic characteristics of cutaneous tissue samples from patients with hidradenitis suppurativa (HS) are not currently standardized, limiting clinicians' and scientists' ability to uniformly record, report, and communicate about the characteristics of tissue used in translational experiments. A recently published consensus statement outlined morphological definitions of typical HS lesions, but no consensus has been reached regarding clinical characterization and examination of HS tissue samples. In this study, we aimed to establish a protocol for reporting histopathologic and clinical characteristics of HS tissue specimens.

Development of the acne-specific quality of life questionnaire Quality of Life Relevance-Acne.

Background: Participating members of the European Academy of Dermatology and Venereology Task Forces on quality of life (QoL) and Patient Oriented Outcomes and Acne, Rosacea and Hidradenitis Suppurativa initiated data collection in 9 European countries and formed the list of the most relevant topics for acne patients.

Objective: The aim of this study was to develop a new acne-specific health-related QoL instrument based on the list of the most relevant topics for acne patients.

Methods: After assessment by acne patients ( = 715) on how clear and relevant the items in the prototype questionnaire were, a group of experts on acne and QoL performed discussions on items inclusion, which resulted in a series of 21 items.
