In a paper published at the J Invest Dermatol in 1998 Nik Kollias and coworkers described distinct changes in skin native fluorescence associated with skin aging and photoaging, using in vivo fluorescence excitation spectroscopy. The assignment of the 295 nm band to tryptophan fluorescence had a profound significance influencing many later studies from multiple groups. The reproducible changes in skin native fluorescence suggested that aging causes predictable alterations in both the epidermis and the dermis, whereas chronic UV exposure induces the appearance of new fluorophores. This seminal, but insufficiently widely appreciated work deserves re-examination as it points to important horizons in future experimental dermatology, such as cancer diagnostics, diabetes, wound healing, and understanding skin aging and photoaging mechanisms.

Improving apgar scores and reducing perineal injuries through midwife-led quality improvements: an observational study in Uganda.
BMC Public Health
January 2025
Department of Women's and Children's Health, Karolinska Institutet, Tomtebodavägen 18A, Stockholm, Solna, 171 77, Sweden.
Background: Globally, the quality of maternal and newborn care remains inadequate, as seen through indicators like perineal injuries and low Apgar scores. While midwifery practices have the potential to improve care quality and health outcomes, there is a lack of evidence on how midwife-led initiatives, particularly those aimed at improving the use of dynamic birth positions, intrapartum support, and perineal protection, affect these outcomes.
Objective: To explore how the use of dynamic birth positions, intrapartum support, and perineal protection impact the incidence of perineal injuries and the 5-min Apgar score within the context of a midwife-led quality improvement intervention.
Burden of Fungal Skin Diseases in Five East Asian Countries: An Analysis of the Global Burden of Disease Study 2021.

Introduction: The unique natural and social environments of East Asia may shape the characteristics of fungal skin diseases. However, there is a notable absence of thorough comparative analyses on this subject.
Methods: This research undertook a comprehensive analysis of the epidemiology and disease burden of fungal dermatoses across five East Asian countries (China, Japan, Republic of Korea, Democratic People's Republic of Korea and Mongolia) via the Global Burden of Disease (GBD) database from 1990 to 2021.

Skin aging, characterized by reduced elasticity, wrinkles, and changes in pigmentation, presents significant challenges in the cosmetics industry. Identifying compounds that can help mitigate these effects is crucial to developing effective anti-aging treatments and improving skin health. An advanced analytical approach for identifying skin anti-aging compounds within complex natural mixtures must be developed to achieve this.

January 2025
Centre for Rheumatology, Division of Medicine, University College London, London, United Kingdom.
Objectives: Systemic sclerosis (SSc)-interstitial lung disease (ILD) is one of the leading causes of mortality in SSc. Data from randomised controlled trials (RCTs) supports rituximab and tocilizumab monotherapy but there is limited data regarding their use for those who fail standard immunomodulatory therapies.
Methods: SSc patients treated with rituximab or tocilizumab were retrospectively identified in a single centre cohort.

Background: Progressive supranuclear palsy (PSP) is the most common primary tauopathy, with a constellation of pathological features including 4R-tau positive neurofibrillary tangles and tufted astrocytes. Most PSP cases are sporadic and associated with common structural variation in the 17q21.31 MAPT locus as well as other loci, including EIF2AK3 which is critical for the integrated stress response (ISR).
