Epigenetics and ultraviolet radiation: Implications for skin ageing and carcinogenesis.

Recent published data have highlighted the importance of epigenetics in the response of the skin to recreational and therapeutic ultraviolet radiation (UVR) exposure. 'Epi'-from the Greek επί, meaning over, outside of or around-relates to the chemical modifications that occur on top of the DNA sequence (for example, DNA methylation) and its associated proteins (e.g.

Using parenclitic networks on phaeochromocytoma and paraganglioma tumours provides novel insights on global DNA methylation.

Despite the prevalence of sequencing data in biomedical research, the methylome remains underrepresented. Given the importance of DNA methylation in gene regulation and disease, it is crucial to address the need for reliable differential methylation methods. This work presents a novel, transferable approach for extracting information from DNA methylation data.

The efficacy of arterial only microsurgical nasal replantation: a systematic review.

Background: Microsurgical nasal replantation is a rare yet important procedure in order to regain the respiratory, olfactory, and aesthetic features of the nose. However, due to the traumatic nature of most nasal amputations, appropriate veins for anastomosis are difficult to find- complicating replantation. This is the first systematic review that compares peri operative and post-operative outcomes in arterial only versus arterial and venous anastomosis for nasal replantation.

Neurological Monitoring and Management for Adult Extracorporeal Membrane Oxygenation Patients: Extracorporeal Life Support Organization Consensus Guidelines.

Background: Critical care of patients on extracorporeal membrane oxygenation (ECMO) with acute brain injury (ABI) is notable for a lack of high-quality clinical evidence. Here, we offer guidelines for neurological care (neurological monitoring and management) of adults during and after ECMO support.

Methods: These guidelines are based on clinical practice consensus recommendations and scientific statements.

Cohort profile: working age adults accessing secondary mental health services in South London (UK) and benefits - a data linkage of electronic mental health records and benefits data.

Introduction: In the UK, mental disorders are one of the most common reasons for claiming a benefit relating to unemployment, income, sickness and disability. Limited information exists regarding the demographic characteristics and psychiatric profiles of working age individuals claiming benefits in London. Until recently, detailed data on both mental disorders and benefit receipt were unavailable.

Change in Patient Perceptions of Electronic Communication Methods for an Orthopaedic Fracture Clinic Between 2019 and 2024.

Introduction Outpatient appointments are essential to patient care, yet rising non-attendance rates ('did not attend' DNAs) pose significant challenges, costing the National Health Service (NHS) over £1 billion annually. Traditional postal communication is inefficient and costly, while digital methods like short messaging service (SMS) and electronic mail (email) show the potential to improve attendance and reduce costs. This study investigates changes in patient preferences for orthopaedic outpatient communication methods between 2019 and 2024 at a busy district general hospital in London, UK.

Targeted anti-cancer agents and risk of venous thromboembolism.

The incidence of one-year venous thromboembolism (VTE) after cancer diagnosis is reported to be increasing for several types of cancer. The introduction of targeted anti-cancer therapies and immunotherapy into the therapeutic armamentarium of medical oncologists contributed to the significantly improved response rates and survival times of cancer patients. In recent years, a potential prothrombotic effect of several targeted anti-cancer agents and immunotherapy drugs has been suggested; however, the methodological limitations of clinical trials evaluating the possible role of these classes of drugs on the VTE risk often make the interpretation of their results difficult.

Surgical Simulation of Kirschner Wiring-Discussion and Review of the Newcastle Surgical Training Centre K-Wiring Course May 2024.

Simulation training has been growing in popularity, as a means to help supplement the training of surgical residents. The Newcastle Surgical Training Centre K-wiring course, a 1-day course designed for early-years surgical trainees, aims to teach essential skills in K-wire fixation for hand fractures. The course integrates lectures and hands-on practice with both simulated and cadaveric specimens, supported by a high faculty-to-delegate ratio.

Assessment of Debris Apical Extrusion, Unprepared Surface Areas, and Dentinal Crack Formation after Root Canal Preparation Using ProTaper Next, ProTaper Ultimate, and R-Motion File Systems.

Introduction: This study evaluated and compared the amount of apically extruded debris, unprepared wall surface areas, and dentinal crack formation resulting from root canal preparation using ProTaper Next (PTN), ProTaper Ultimate (PTU), and R-Motion (RM) file systems.

Methods: Forty-five palatal roots of maxillary first molars were shortened to a uniform length of 12 mm. The samples were divided randomly into 3 groups (n = 15/group) to be prepared using either PTN, PTU, and RM file systems.

Treating eosinophilic exacerbations of asthma and COPD with benralizumab (ABRA): a double-blind, double-dummy, active placebo-controlled randomised trial.

Background: Exacerbations of asthma and chronic obstructive pulmonary disease (COPD) are important events and are associated with critical illness. Eosinophilic inflammation is a treatable trait commonly found during acute exacerbations of asthma and COPD. We hypothesised that for patients with eosinophilic exacerbations, a single injection of benralizumab, a humanised monoclonal antibody against interleukin-5 receptor-α, alone or in combination with prednisolone, will improve clinical outcomes compared with prednisolone, the standard of care.

A Systematic Review of Simulation-Based Training Tools in Plastic Surgery.

Objectives: The recent shift from traditional surgical teaching to the incorporation of simulation training in plastic surgery has resulted in the development of a variety of simulation models and tools. We aimed to assess the validity and establish the effectiveness of all currently available simulators and tools for plastic surgery.

Design: Systematic review.

INSIGHT-2: mechanistic studies into pregnancy complications and their impact on maternal and child health-study protocol.

Background: Pregnancy and early childhood cohorts provide a framework for investigating the complex interplay between early-life exposures and health outcomes, thereby informing prevention strategies and interventions to improve maternal and child health. In this paper, we outline the objectives, methodologies and expected contributions of INSIGHT-2, a comprehensive cohort study dedicated to advancing our understanding of pregnancy and pregnancy complications towards improving the health and well-being of mothers and their offspring.

Methods: Over the course of 5 years, the study aims to establish a diverse cohort of 1700 pregnant women and to follow up their children up to 2 years of age.

Semi automatic quantification of REM sleep without atonia in natural sleep environment.

Polysomnography, the gold standard diagnostic tool in sleep medicine, is performed in an artificial environment. This might alter sleep and may not accurately reflect typical sleep patterns. While macro-structures are sensitive to environmental effects, micro-structures remain more stable.

A modified Delphi consensus regarding the clinical utility of triplet therapy in patients with metastatic hormone-sensitive prostate cancer patients in the UK.

Objectives: This study aimed to determine the clinical utility of the androgen deprivation therapy (ADT)+docetaxel (DOCE)+androgen receptor-targeted agent (ARTA) triplet therapy in patients with metastatic hormone-sensitive prostate cancer (mHSPC) in the UK.

Design: A modified Delphi method. A steering group of eight UK healthcare professionals experienced in prostate cancer care discussed treatment challenges, developing 39 consensus statements across four topics.
