Epidemiology of Breast Cancer in Women.
Epidemiology of Breast Cancer in Women. Adv Exp Med Biol. 2019;1152:9-29 Authors: Coughlin SS Abstract Epidemiologic studies have contributed importantly to current knowledge of environmental and genetic risk factors for breast cancer. Worldwide, breast cancer is an important cause of human suffering and premature mortality among women. In the United States, breast cancer accounts for more cancer deaths in women than any site other than lung cancer. A variety of risk factors for breast cancer have been well-established by epidemiologic studies including race, ethnicity, family history of cancer, and genetic traits, as well as modifiable exposures such as increased alcohol consumption, physical inactivity, exogenous hormones, and certain female reproductive factors. Younger age at menarche, parity, and older age at first full-term pregnancy may influence breast cancer risk through long-term effects on sex hormone levels or by other biological mechanisms. Recent studies have suggested that triple negative breast cancers may have a distinct etiology. Genetic variants and mutations in genes that code for proteins having a role in DNA repair pathways and the homologous recombination of DNA double stranded breaks (APEX1, BRCA1, BRCA2, XRCC2, XRCC3, ATM, CHEK2, PALB2, RAD51, XPD), have been implicated in some cases of breast cancer.

Conclusions: Smoking and substance abuse are common among industrial workers. Tramadol and cannabis are the most commonly abused substances. Smoking, older age, and male sex are correlates of substance abuse. Alcohol abuse is associated with dependence.
Conclusions: These findings show that in Brazil problems related to alcohol use by the elderly remain relatively unknown. There was a high heterogeneity of methodologies in the studies, making it difficult to summarize the findings and produce prevalence estimates for the different patterns of consumption. More homogenous studies using similar definitions of patterns of alcohol consumption are required to allow comparisons to be made between different Brazilian regions and other countries.
This is a public health success story. A landmark report on the effectiveness of the quadrivalent human papillomavirus vaccine (4vHP) in the U.S. is now a matter of medical record. Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the U.S., with nearly 80 million people infected with some type of HPV at some point in their lives . About 14 million Americans, including teens, become infected each year . HPV causes genital warts and is associated with an estimated 33,700 newly diagnosed cancers every year in the U.S.
Authors: Liu X, Yang G, Huang J, Chai L, Liu X, Dai Q, Yang Z Abstract Aim: KRAS SNPs may increase KRAS transcription and KRAS levels. SNPs of KRAS 3'UTR can affect carcinoma risk and prognosis. Materials &methods: The rs8720 and rs7960917 in KRAS 3'UTR for colorectal carcinoma (CRC) risk and survival were investigated in a case-control study. Association between SNPs and CRC risk, survival analysis were analyzed by an unconditional logistic regression model, log-rank test, Kaplan-Meier estimation, Cox regression model and one-way analysis of variance. Results &conclusion: The genotype CT of rs8720 was sign...
This study profiled differentially expressed long noncoding RNAs (lncRNAs) in lung squamous cell carcinoma (LSCC) to predict LSCC overall survival (OS) using The Cancer Genome Atlas data. Materials &methods: The RNA-seq and clinical dataset of 475 LSCC patients was retrieved from The Cancer Genome Atlas database and statistically analyzed. Results: There were 67 upregulated and 32 downregulated lncRNAs in LSCCs and 12 lncRNAs associated with OS. The seven-lncRNA signature was associated with poor OS and RP11-150O12.6 and CTA-384D8.35 were associated with better OS (p
In this study, the obtained IC50 concentration of 51.25 μg/mL exhibits significant anticancer activity against A549 cells than other tested concentrations because of the release of zinc ions, which induce the cell apoptosis. Furthermore, studies on cell cycle validate that ZnO NPs arrest the cell cycle at the sub-G1 phase of A549 cells. These results suggest the utility of phytogenic ZnO NPs for various biomedical applications.Graphical abstract
Authors: Demers AA, Brenner DR, Smith L, Shaw A Abstract Examining incidence trends of all cancers combined in order to understand cancer trends can be misleading, as patterns can vary across individual cancer types. This paper highlights findings on trends over time from Canadian Cancer Statistics 2019, as measured by the annual percent change (APC) of age-standardized incidence rates. Among the results were a recent increase in thyroid cancer in males (APC: 6.4%, 1997-2015), as well as decreases in prostate cancer (APC: -9.1%, 2011-2015) and cervical cancer (APC: -3.3%, 2010-2015).

CONCLUSION: Starting to drink alcohol in the early teen years predicted current alcohol use, current binge drinking and mixing of alcohol with energy drinks when students were in Grade 12. Findings indicate a need for development of novel alcohol prevention efforts. PMID: 31729312 [PubMed - in process]
CONCLUSION: CHIRPP in Montréal proved a valid tool for estimating the variations in rates of mTBI in the population. This suggests that CHIRPP could also be used to estimate population-based rates of other types of injuries. PMID: 31729311 [PubMed - in process]
Conclusions: Population level of iAs% and DMA%, but not MMA%, were associated with arsenic exposure levels. Overall, study findings suggest that higher MMA% was associated with an increased risk of cancer and cardiovascular disease, while lower MMA% was associated with an increased risk of diabetes and metabolic syndrome. Additional population-based studies and experimental studies are needed to further evaluate and understand the role of arsenic exposure in arsenic metabolism and the role of arsenic metabolism in disease development. https://doi.org/10.1289/EHP577 Received: 01 June 2016 Revised: 26 February 2017 Acce...
