Author Interviews, Brigham & Women's - Harvard, Cancer Research, Dermatology / 03.09.2020

MedicalResearch.com Interview with: Yin Zhang MD Research Fellow in Medicine Brigham and Women's Hospital and Harvard Medical School MedicalResearch.com: What is the background for this study? Response: Among modern hair dyes, permanent hair dye is the most popular type, and is the most aggressive and extensively used type that has posed the greatest potential concern about cancer risk. Monitoring and investigating the carcinogenic hazard to people from personal use of permanent hair dyes has major public health implications. In 2008, the World Health Organization's International Agency for Research on Cancer, after comprehensive reviewed prior evidence, classified occupational exposure to hair dyes as a probable carcinogen to humans (group 2A), whereas personal use of hair dyes was not classifiable as to its carcinogenicity to humans (Group 3). Data on hair dye safety has also been continuously monitored by the USFDA. Prior epidemiological evidence may have been influenced by not discriminating between personal and occupational exposure, an inability to distinguish types and colors of hair dyes used, imprecise assessment of several critical domains of exposure history (duration, frequency and cumulative dose), and inadequate control for potential confounding.

Author Interviews, Cancer Research, Gender Differences, Genetic Research / 21.01.2020

MedicalResearch.com Interview with: Alejandro Cáceres PhD Juan R. González, PhD Barcelona Institute for Global Health (ISGlobal) Barcelona, Spain. MedicalResearch.com: What is the background for this study? What are the main findings? Response: Men have more risk and worse prognosis to cancer than women. There are many environmental factors but also biological differences. We find that the loss of function of six genes (DDX3Y, EIF1AY, KDM5D, RPS4Y1, UTY and ZFY) in chromosome Y is one of the biological factors for the differences between sexes in relation to cancer risk and prognosis.  (more…)
Author Interviews, Cancer Research, UT Southwestern, Weight Research / 13.03.2017

MedicalResearch.com Interview with: Arjun Gupta, MD and Ian J. Neeland MD, Assistant Professor Dedman Family Scholar in Clinical Care Division of Cardiology UT Southwestern Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adiposity is traditionally measured using the body mass index, which refers to a persons weight in kilograms divided by their height (in meters) squared. Persons with higher body mas index have been shown to have increased risk of certain cancers, however body mass index by itself is not a completely representative measure of body fat risk, because distinct fat depots such as visceral adipose tissue, abdominal subcutaneous adipose tissue, liver fat and lower body fat have differing metabolic impact. We aimed to study the relationship between specific fat depots and the risk of incident cancer among relatively young, multiethnic participants in the Dallas Heart Study. Individuals without prevalent cancer underwent quantification of adipose depots using MRI and DEXA scans from 2000-2002, and were followed for the development of cancer for up to 12 years. In multivariable models adjusted for age, sex, race, smoking, alcohol use, family history of malignancy and body mass index, visceral adipose tissue, subcutaneous adipose tissue or liver fat were not associated with risk of cancer but each 1-standard deviation increase in lower body fat was associated with a 31% reduced incidence of cancer.

Author Interviews, Hepatitis - Liver Disease / 26.04.2013

MedicalResearch.com: eInterview with: Soo Aleman Department of Gastroenterology and Hepatology, and Infectious Diseases Karolinska University Hospital, at Karolinska Institute 171 76 Stockholm, Sweden,Soo Aleman Department of Gastroenterology and Hepatology, and Infectious Diseases Karolinska University Hospital, at Karolinska Institute 171 76 Stockholm, Sweden, MedicalResearch.com: What are the main findings of the study? Answer: In this long-term, prospective study of 351 hepatitis C infected patients with liver cirrhosis, we found a reduced but persistent risk for hepatocellular cancer after successful treatment with eradication of the virus. This risk for hepatocellular cancer remained at a level of 1% per year for those with sustained virological response, and could persist as long as 8 years after eradication. (more…)

MedicalResearch.com eInterview with Vincent Yi-Fong Su MD Department of Chest Medicine, Taipei Veterans General Hospital, Taipei, Taiwan MedicalResearch.com: What are the main findings of the study? Answer: Amiodarone, one of the most widely used medications to treat arrhythmias may increase the risk of developing cancer, especially in men and people exposed to high amounts of the drug. That is the conclusion of a new retrospective study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. Patients who were male or who received high cumulative daily doses of amiodarone within the first year had an increased risk of developing cancer. Those with both factors were 46 percent more likely to develop cancer than those with neither factor. (more…)
