Research on carcinogenesis and its inhibition has made significant progress in the last 30 years, providing an impressive body of evidence that supports various strategies for cancer prevention. Innovative studies have helped to identify potential causes of cancer, including environmental factors such as diet, and provided valuable information about their mechanisms of action. Hundreds of epidemiologic and experimental studies have focused on possible associations between dietary factors and different types of cancer. During the same period, potential inhibitors of cancer that appeared able to prevent, arrest or reverse cancer development by interfering with one or more steps in the process of carcinogenesis were identified, and the term 'chemoprevention' was coined for this pharmacological approach to cancer prevention. Promising compounds were systematically evaluated for their potential as chemopreventive agents. Numerous agents were determined to be safe and effective in preclinical trials, including naturally occurring vitamins, minerals and phytochemicals as well as synthetic compounds. Based on preclinical results, selected agents have been and are now being evaluated in phase I, II and III clinical interventions for various cancers. Development of valid surrogate end point biomarkers for clinical disease that can be modulated by interventions is essential to accelerate progress in cancer prevention clinical trials.

Background: Understanding based on up-to-date data on the burden of non-communicable diseases (NCDs) is limited, especially regarding how subtypes contribute to the overall NCD burden and the attributable risk factors across locations and subtypes. We aimed to report the global, regional, and national burden of NCDs, subtypes, and attributable risk factors in 2021, and trends from 1990 to 2021 by age, sex, and socio-demographic index (SDI).
Materials And Methods: We used data from the Global Burden of Disease Study 2021 to estimate the prevalence, deaths, and disability-adjusted life years (DALYs) for NCDs and subtypes, along with attributable risk factors.

Colorectal cancer (CRC) is a malignant tumor that originates from the epithelial cells of the colon and rectum. Global epidemiological data shows that in 2020, the incidence and mortality rate of CRC ranked third and second, respectively, posing a serious threat to people's health and lives. The factors influencing CRC are numerous and can be broadly categorized as modifiable and non-modifiable based on whether they can be managed or intervened upon.

Introduction: What interventions effectively prevent postoperative stenosis following endoscopic resection (ER) of superficial esophageal cancer? This study aimed to identify effective interventions or combinations through a systematic review and network meta-analysis.
Methods: Six databases were systematically searched for eligible studies up to 30 April 2023, on interventions to prevent esophageal stenosis post-ER. Odds ratios (ORs) evaluated stenosis rate (primary outcome) and complications (secondary outcome), while mean differences (MD) evaluated endoscopic balloon dilatation (EBD) sessions post-stenosis.

Bromopropane was introduced commercially as an alternative to ozone-depleting and global warming solvents. The identification of 1-bromopropane neurotoxicity in animal experiments was followed by reports of human cases of 1-bromopropane toxicity. In humans, the most common clinical features of 1-bromopropane neurotoxicity are decreased sensation, weakness in extremities, and walking difficulties.

Importance: In the Atrial Cardiopathy and Antithrombotic Drugs in Prevention After Cryptogenic Stroke (ARCADIA) randomized clinical trial, anticoagulation did not prevent recurrent stroke among patients with a recent cryptogenic stroke and atrial cardiopathy. It is unknown whether anticoagulation prevents covert infarcts in this population.
Objective: To test the use of apixaban vs aspirin for prevention of nonlacunar covert infarcts after cryptogenic stroke in patients with atrial cardiopathy.
