Article Synopsis
  • - A global study conducted from January to April 2023 assessed pruritus (itching) prevalence among 50,552 individuals across 20 countries, revealing an overall prevalence of 39.8%.
  • - The study found that older adults (65+) had the highest prevalence at 43.3%, with women experiencing pruritus more frequently (40.7%) than men (38.9%).
  • - Geographic differences showed higher pruritus rates in Africa (45.7%) compared to North America (41.2%) and lower rates in Europe (35.9%) and Australia (38.4%), with no notable ethnic differences in prevalence.

Background: The journey of patients with skin diseases through healthcare has been scarcely investigated.

Objective: To analyse the journey of people with skin diseases in the different healthcare environment in Europe.

Methods: This multinational, cross-sectional, European study was conducted on a representative sample of the adult general population of 27 European countries.

Background: Several large studies on the burden of skin diseases have been performed in patients recruited in hospitals or clinical centres, thus missing people with skin diseases who do not undergo a clinical consultation.

Objectives: To evaluate the burden of the most common dermatological diseases in adult patients across Europe, in terms of quality of life, work life, and stigmatization.

Methods: Population-based survey on a representative sample of the European general population aged 18 years or older.

Background: The public perception of dermatology has been poorly investigated in Europe.

Objective: To determine the general public's perception of dermatologists in Europe.

Methods: This multinational, cross-sectional study was conducted within the framework of the EADV population-based survey on the 'Burden of skin diseases in Europe'.

Background: Psoriasis is a chronic inflammatory skin disease that has a profound effect on health-related quality of life (HRQoL). Patient education programmes may help patients to gain life-long control over their chronic disease.

Objective: This multicentre randomised controlled study evaluated whether a standardised multidisciplinary education programme was beneficial to psoriasis patients.

Brown adipose tissue (BAT) has long been described according to its histological features as a multilocular, lipid-containing tissue, light brown in color, that is also responsive to the cold and found especially in hibernating mammals and human infants. Its presence in both hibernators and human infants, combined with its function as a heat-generating organ, raised many questions about its role in humans. Early characterizations of the tissue in humans focused on its progressive atrophy with age and its apparent importance for cold-exposed workers.

Background: Although infliximab (IFX) has been available since 2005, there are very little data on the long-term drug survival of infliximab in real-life.

Objective: Our aim was to identify and describe psoriasis patients treated with IFX for longer than 6 years.

Methods: Psoriasis patients treated with IFX for longer than 6 years were retrospectively included.

Background: [C]-acetate positron emission tomography is used to assess oxidative metabolism in various tissues including the heart, tumor, and brown adipose tissue. For brown adipose tissue, a monoexponential decay model is commonly employed. However, no systematic assessment of kinetic models has been performed to validate this model or others.

Background: Chronic hand eczema is an inflammatory dermatosis that results in a significant psychological and socio-economic burden. Alitretinoin (AL) is indicated in adults with severe chronic hand eczema (sCHE) unresponsive to potent topical corticosteroids.

Objectives: To assess AL effectiveness and safety in patients with sCHE under real-life conditions based on a prospective observational study in France (2010-2014).

The Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity-Score (ABSIS) scores have been proposed to provide an objective measure of pemphigus activity. These scores have been evaluated only on already treated patients mainly with mild to moderate activity. The objective was to assess the interrater reliability of ABSIS and PDAI scores and their correlation with other severity markers in a large international study.

Background: In Alzheimer's disease (AD), it is unknown whether the brain can utilize additional ketones as fuel when they are derived from a medium chain triglyceride (MCT) supplement.

Objective: To assess whether brain ketone uptake in AD increases in response to MCT as it would in young healthy adults.

Methods: Mild-moderate AD patients sequentially consumed 30 g/d of two different MCT supplements, both for one month: a mixture of caprylic (55%) and capric acids (35%) (n = 11), followed by a wash-out and then tricaprylin (95%; n = 6).

Objectives: Mechanisms underlying sepsis-associated encephalopathy remain unclear, but reduced cerebral blood flow, alone or in conjunction with altered autoregulation, is reported as a potential contributor. We compared cerebral blood flow of control subjects and vasopressor-dependent septic patients.

Design: Randomized crossover study.

-(2-F-fluoroethyl)-l-tyrosine (F-FET) is a radiolabeled artificial amino acid used in PET for tumor delineation and grading. The present study compares different kinetic models to determine which are more appropriate for F-FET in rats. Rats were implanted with F98 glioblastoma cells in the right hemisphere and scanned 9-15 d later.

The body's main fuel sources are fats, carbohydrates (glucose), proteins, and ketone bodies. It is well known that an important hallmark of cancer cells is the overconsumption of glucose. Positron emission tomography (PET) imaging using the glucose analog (18)F-fluorodeoxyglucose ((18)F-FDG) has been a powerful cancer diagnostic tool for many decades.

Blood samples obtained by arterial cannulation are the gold standard to measure the input function for PET pharmacokinetic modeling. There is interest in less invasive methods, such as image-derived input functions (IDAIF). MRI can be used to segment and correct partial volume effects of the PET images, improving IDAIF extraction.

Whatever the improvement in the protection spectrum of sunscreens (SCs), actual skin protection mainly depends on the way they are used, especially on the quantity applied. This prospective randomized study assessed how much sun protection factor (SPF) labeling, which is hardly understandable by a layman, and high cost account for misuse of SCs. In three beach resorts in France, 364 individuals were blindly randomized during their holidays to three arms (1) free SCs intervention (FS) = four types of SCs with their usual SPF label (60B-A, 20B-A, 12B-A, 6B-3A) at free disposal; (2) same free SCs with an explicit labeling (FNL), including sunburn protection, likely protection against long-term effects of UV, and possibility to get a tan; and (3) no intervention (NI).
