Atopic dermatitis and tobacco smoke exposure during childhood and adolescence.

Background: Tobacco smoke may affect atopic dermatitis (AD) because of its known effects on humoral and cellular immunity, but prior studies lack data on disease severity and biomarkers over time.

Objective: We investigated the association between passive and active tobacco smoke exposure (TSE) during childhood and adolescence and the activity and severity of AD.

Methods: A birth cohort of 10,521 individuals was followed through adolescence as part of the Avon Longitudinal Study of Parents and Children.

Cohort studies on 71 outcomes among people with atopic eczema in UK primary care data.

Atopic eczema may be related to multiple subsequent adverse health outcomes. Here, we provide evidence to judge and compare associations between eczema and a comprehensive set of outcomes. We conducted 71 cohort studies (age, sex, general practice-matched) using Clinical Practice Research Datalink Aurum primary care records (1997-2023), comparing up to 3.

Impacts of the COVID-19 pandemic on deprivation-level differences in cardiovascular hospitalisations: a comparison of England and Denmark using the OpenSAFELY platform and National Registry Data.

Objectives: To examine the impact of the COVID-19 pandemic on deprivation-related inequalities in hospitalisations for cardiovascular disease (CVD) conditions in Denmark and England between March 2018 and December 2021.

Design: Time-series studies in England and Denmark.

Setting: With the approval of National Health Service England, we used English primary care electronic health records, linked to secondary care and death registry data through the OpenSAFELY platform and nationwide Danish health registry data.

Core Concepts in Pharmacoepidemiology: Quantitative Bias Analysis.

Pharmacoepidemiological studies provide important information on the safety and effectiveness of medications, but the validity of study findings can be threatened by residual bias. Ideally, biases would be minimized through appropriate study design and statistical analysis methods. However, residual biases can remain, for example, due to unmeasured confounders, measurement error, or selection into the study.

Educational, labour market and relationship outcomes in people with acne.

Background: Although acne is associated with scarring, mental health comorbidities and bullying, little is known about its impact on socio-economic outcomes.

Objectives: To examine the association between acne and educational, labour market and relationship outcomes.

Methods: We conducted a nationwide registry-based cohort study in Denmark.

Muscle Quality and Physical Function in Men With and Without HIV.

Background: People with HIV (PWH) experience faster physical decline than those without HIV (PWoH), despite antiretroviral therapy. We compared skeletal muscle density and area and their relationship with physical function among PWH and PWoH.

Methods: Quantitative computed tomography scans were performed at the L4-L5 spinal region and the thigh to evaluate muscle groups in Multicenter AIDS Cohort Study participants at baseline.

Breadth and polyfunctionality of T cell responses to human cytomegalovirus in men who have sex with men: relationship with HIV infection and frailty.

Unlabelled: Cytomegalovirus (CMV)-seropositive adults have large T cell responses to a wide range of CMV proteins; these responses have been associated with chronic inflammation and frailty in people with or without HIV infection. We analyzed the relationships between chronic HIV infection, frailty, and the breadth and polyfunctionality of CD4 and CD8 T cell responses to CMV. Peripheral blood mononuclear cells from 42 men (20 without HIV and 22 with virologically suppressed HIV) in the Multicenter AIDS Cohort Study (MACS) were stimulated with peptide pools spanning 19 CMV open reading frames (ORFs).

Broadening the View of Holistic Care: Integrating Arts and Humanities Into Physician Assistant Education.

Introduction: The integration of arts and humanities (A&H) into physician assistant (PA) preclinical curriculum may enhance student performance and improve their patient rapport. Arts and humanities content could promote the personal and professional qualities we desire in clinicians including competence, compassion, and empathy. The aim of this research was to determine what PA students report learning from A&H modules designed to foster personal insight and perspective-taking.

Urticaria and the risk of cancer: a Danish population-based cohort study.

Background: Urticaria has been tentatively linked to cancer, but epidemiological evidence supporting this link is sparse and conflicting. We conducted a population-based cohort study using healthcare databases covering the Danish population (January 1980-December 2022). We followed 87 507 people for a median of 10.

Antihypertensive Medications and Eczematous Dermatitis in Older Adults.

Importance: Rates of physician-diagnosed eczema have been increasing among older adults, but little is known regarding the pathophysiologic processes and best treatments in this subgroup. Preliminary data suggest that medications-antihypertensive medications in particular-may contribute to eczematous dermatitis; however, there are limited population-based data on the proportion of eczematous dermatitis diagnoses among older adults that may be attributed to antihypertensive drugs.

Objectives: To determine whether antihypertensive drug use is associated with eczematous dermatitis in older adults.

Validation of algorithms in studies based on routinely collected health data: general principles.

Clinicians, researchers, regulators, and other decision-makers increasingly rely on evidence from real-world data (RWD), including data routinely accumulating in health and administrative databases. RWD studies often rely on algorithms to operationalize variable definitions. An algorithm is a combination of codes or concepts used to identify persons with a specific health condition or characteristic.

Disagreement concerning atopic dermatitis subtypes between an English prospective cohort (ALSPAC) and linked electronic health records.

Background: Subtypes of atopic dermatitis (AD) have been derived from the Avon Longitudinal Study of Parents and Children (ALSPAC) based on the presence and severity of symptoms reported in questionnaires (severe-frequent, moderate-frequent, moderate-declining, mild-intermittent, unaffected-rare). Good agreement between ALSPAC and linked electronic health records (EHRs) would increase trust in the clinical validity of these subtypes and allow inference of subtypes from EHRs alone, which would enable their study in large primary care databases.

Objectives: Firstly, to explore whether the presence and number of AD records in EHRs agree with AD symptom and severity reports from ALSPAC.

Antihypertensive Medications and Risk of Melanoma and Keratinocyte Carcinomas: A Systematic Review and Meta-Analysis.

Some antihypertensive medications are photosensitizing. The implications for skin cancer risk remain unclear because results from prior studies are inconsistent and as new evidence is published. We performed a systematic review and meta-analysis to evaluate the association between antihypertensives and common skin cancers (cutaneous squamous cell carcinoma, basal cell carcinoma, and melanoma) and to evaluate dose-response relationships.

Ethnic differences in depression and anxiety among adults with atopic eczema: Population-based matched cohort studies within UK primary care.

Background: Evidence demonstrates that individuals with atopic eczema (eczema) have increased depression and anxiety; however, the role of ethnicity in these associations is poorly understood. We aimed to investigate whether associations between eczema and depression or anxiety differed between adults from white and minority ethnic groups in the UK.

Methods: We used UK Clinical Practice Research Datalink GOLD to conduct matched cohort studies of adults (≥18 years) with ethnicity recorded in primary care electronic health records (April 2006-January 2020).

Online behavioural interventions for children and young people with eczema: a quantitative evaluation.

Background: Two online behavioural interventions (one website for parents/carers of children with eczema; and one for young people with eczema) have been shown in randomised controlled trials to facilitate a sustained improvement in eczema severity.

Aim: To describe intervention use and examine potential mediators of intervention outcomes and contextual factors that may influence intervention delivery and outcomes.

Design And Setting: Quantitative process evaluation in UK primary care.
