Increased cancer incidence in “cold” countries: An (un)sympathetic connection?

Publication date: Available online 15 February 2020Source: Journal of Thermal BiologyAuthor(s): Boris Mravec, Miroslav TibenskyAbstractPublished data has shown that there is an unexpected, significantly increased cancer mortality and incidence in countries with low or subnormal environmental temperatures. There have been several hypotheses developed to elucidate the mechanisms behind these findings. It is well documented that cold represents a very efficient stressor that activates sympathetic nerves and increases tissue and plasma norepinephrine levels. Importantly, recently accumulated data indicate that norepinephrine can stimulate carcinogenesis and the progression of cancer. Therefore, we suggest that the effect of a cold environment on cancer incidence and mortality might be mediated, at least partially, by norepinephrine released from sympathetic nerves in response to cold. Data supporting this hypothesis are discussed here and potential preventive approaches are described.

CONCLUSION: En bloc transurethral resection using 980 nm laser is an effective and safe treatment option for non-muscle-invasive bladder cancer. Compared to the traditional TUR-Bt procedure, the procedure using 980 nm laser has fewer perioperative complications and similar oncological results.

AbstractBackgroundTo evaluate the surgical safety of en bloc resection of bladder tumor (ERBT) and the effectiveness of ERBT combined with near-infrared (NIR) imaging technique in the diagnosis and treatment of non-muscle invasive bladder cancer (NMIBC).MethodsFrom October 2017 to June 2018, 26 patients newly diagnosed with single NMIBC were included in this retrospectively trial. All patients received ERBT with monopolar current. After surgery, the fresh specimen was incubated with anti-CD47-Alexa Fluor 790, and then imaged under NIR imaging technique. Operative details, intraoperative and postoperative complications of E...

Authors: Kruk J, Kotarska K, Aboul-Enein BH Abstract Beneficial effect of regular moderate physical exercise (PE) and negative effect of severe exercise and/or overtraining as an activator of the sympathetic nervous system (SNS) have been shown in numerous aspects of human health, including reduced risk of cardiovascular disease, neurological disease, depression, and some types of cancer. Moderate-to-vigorous PE stimulates the SNS activation, releasing catecholamines (CATs) adrenaline, noradrenaline, dopamine that play an important regulatory and modulatory actions by affecting metabolic processes and the immune sy...
