Arsenic exposure: A public health problem leading to several cancers. Regul Toxicol Pharmacol. 2019 Nov 22;:104539 Authors: Palma-Lara I, Martínez-Castillo M, Quintana-Pérez JC, Arellano-Mendoza MG, Tamay-Cach F, Valenzuela-Limón OL, García-Montalvo EA, Hernández-Zavala A Abstract Arsenic, a metalloid and naturally occurring element, is one of the most abundant elements in the earth's crust. Water is contaminated by arsenic through natural sources (underground water, minerals and geothermal processes) and anthropogenic sources such as mining, industrial processes, and the production and use of pesticides. Humans are exposed to arsenic mainly by drinking contaminated water, and secondarily through inhalation and skin contact. Arsenic exposure is associated with the development of vascular disease, including stroke, ischemic heart disease and peripheral vascular disease. Also, arsenic increases the risk of tumors of bladder, lungs, kidneys and liver, according to the International Agency for Research on Cancer and the Food and Drug Administration. Once ingested, an estimated 70-90% of inorganic arsenic is absorbed by the gastrointestinal tract and widely distributed through the blood to different organs, primarily to the liver, kidneys, lungs and bladder and secondarily to muscle and nerve tissue. Arsenic accumulates in the organs, especially in the liver. Its excretion mostly takes place through urination. The toxicokine...

We reviewed this concept considering recent results in the field.Areas covered: Herein, the authors cover neoadjuvant chemotherapy with or without biologics in triple-negative and HER2-positive operable breast cancer with a focus on rates of complete pathological remission (pCR) in the breast and axilla. The impact of the CREATE X and KATERINE randomi...

One of the biggest challenges of this unsettling time is the isolation we feel as we’re separated from friends and family, all the people for whom we care most deeply. But just being alone is only part of the difficulty. Our sense of remoteness is intensified by a pall of unease we can’t define: Loss and sorrow are also in the air. We fear losing—or we may have already lost—people we love. And when we work up the courage to look beyond our individual personal spheres, we see that many people who have made our world better, in big and small ways, have vanished before we were ready to let them go. But...
