Association between tobacco advertising policies, health warning mandates and adolescents' exposure to tobacco advertising and warning labels in 80 countries.

Background: Implementation of tobacco advertising, promotion and sponsorship (TAPS) bans and of health warning mandates varies by country, and their impact on adolescents' exposure to tobacco-related messages is not well understood, particularly in low-income and middle-income countries.

Aim: To explore the association of the implementation of TAPS bans and health warning mandates with the proportion of adolescents exposed to tobacco advertisements and health warnings in 80 countries from 2016 to 2021.

Methods: The proportion of 11-17 years old exposed to tobacco advertising was assessed using Global Youth Tobacco Survey data (80 countries, n=428 347).

A novel approach to the prevention and management of chemotherapy-induced cardiotoxicity: PANoptosis.

As a fundamental component of antitumor therapy, chemotherapy-induced cardiotoxicity (CIC) has emerged as a leading cause of long-term mortality in patients with malignant tumors. Unfortunately, there are currently no effective therapeutic preventive or treatment strategies, and the underlying pathophysiological mechanisms of CIC remain inadequately understood. A growing number of studies have shown that different mechanisms of cell death, such as apoptosis, pyroptosis, and necroptosis, are essential for facilitating the cardiotoxic effects of chemotherapy.

Dynamic changes and influential factors of blowouts in a desert artificial ecosystem at the southeastern margin of Tengger Desert in China.

The wind-blown sand protection system in the Shapotou section of the Baotou-Lanzhou Railway is a representative artificial ecosystem in a desert region. Over the past 70 years, this system has transformed mobile dunes into fixed dunes through vegetation succession, relying solely on natural rainfall without additional irrigation. However, ecosystem sustainability has been endangered by the emergence of numerous blowouts.

Short-term outcomes of preoperative computed tomography angiography versus standard assessment in patients with BMI ≥ 25.0 kg/m undergoing laparoscopic gastrectomy: the GISSG20-01 randomized clinical trial.

Background: Laparoscopic gastrectomy lacks hand-direct tactile sense and has a limited surgical field compared to laparotomy. Apart from textbook classification, there are anatomical variations in the gastric arteries. Laparoscopic gastrectomy presents technical difficulties and necessitates a more comprehensive comprehension of regional anatomy than open surgical procedures.

Targeting hyaluronan synthesis enhances the therapeutic effectiveness of biologics in inflammatory bowel disease.

Although biologics have been revolutionizing the treatment of inflammatory bowel diseases (IBD) over the past decade, a significant number of patients still fail to benefit from these drugs. Overcoming the nonresponse to biologics is one of the top challenges in IBD treatment. In this study, we revealed that hyaluronan (HA), an extracellular matrix (ECM) component in the gut, is associated with nonresponsiveness to infliximab and vedolizumab therapy in patients with IBD.
