This pan‐European study reveals high rates of addiction in patients with chronic skin diseases. Smoking, alcohol, drug use, gambling, and internet addiction were prevalent and associated with quality of life, demographics, and region. The findings support integrating addiction screening into dermatologic care to improve outcomes.

The vertex Zagreb indices of some graph operations
Recently, Tavakoli et al. introduced a new version of Zagreb indices, named as vertex Zagreb indices. In this paper explicit expressions of different graphs operations of vertex Zagreb indices are presented and also as an application, explicit formulas ...

Hyaluronic acid: A novel approach in regenerative/reconstructive periodontal therapy?
Abstract Background Although hyaluronic acid (HA) has long been used for many medical applications, only in recent years has it gained greater popularity in the field of periodontics because of its biological effects during wound healing. Even today, most clinicians are not aware that more than one type of HA exists and that the extent of its ...

Let ${\mathcal G}_n$ be the set of class of graphs of order $n$. The first Zagreb index $M_1(G)$ is equal to the sum of squares of the degrees of the vertices, and the second Zagreb index $M_2(G)$ is equal to the sum of the products of the degrees of pairs of adjacent vertices of the underlying molecular graph $G$.

A Unified Approach for Extremal General Exponential Multiplicative Zagreb Indices
The study of the maximum and minimal characteristics of graphs is the focus of the significant field of mathematics known as extreme graph theory. Finding the biggest or smallest graphs that meet specified criteria is the main goal of this discipline ...

ABSTRACT The current methods of amending scholarly literature are inadequate; correction notices are often issued indiscriminately, irrespective of the magnitude of the related error. In this cross‐sectional study, we investigated how authors of articles accepted at the Journal of Global Health between 2021 and 2023 perceive the impact of errata to the

Hyper Zagreb indices of composite graphs
For a (molecular) graph, the first Zagreb index M1 is equal to the sum of squares of the degrees of vertices, and the second Zagreb index M2 is equal to the sum of the products of the degrees of pairs of adjacent vertices.

Infrastructure expansion, tourism and electoral outcomes
Abstract This paper examines the electoral impact of economic growth through increased foreign tourism using data from Croatia. To identify causal effects, the paper applies an instrumental variable strategy, which uses variation in the ruggedness of the local terrain to estimate the network of least‐cost paths.

ABSTRACT Purpose Patient activation—encompassing knowledge, confidence, and skills in managing individual's health—is a cornerstone of person‐centered care. However, its significance among childhood, adolescent, and young adult cancer survivors (CAYACS) remains unexplored. This article examines the application of the 13‐item Patient Activation Measure (
