Authors: Yu L, Li P, Yang S, Guo P, Zhang X, Liu N, Wang J, Zhang W Abstract Aim: Breast cancer is a leading cause of cancer among women. Because guidelines on screening for breast cancer for certain ages are controversial, many experts advocate the use of shared decision making (SDM) using validated decision aids (DAs). Recent studies have concluded that DAs are beneficial; however, the results have great heterogeneity. Therefore, further studies are needed to improve understanding of these tools. Objective: This systematic review and meta-analysis aimed to investigate the impact of using web-based DAs in women ag...

In Reply In their letter about our cluster randomized clinical trial of a mammography screening decision aid (DA) for women 75 years and older, Donzelli and Giudicatti recommended that the DA be more explicit about the lack of data that mammography screening extends life. To inform the DA, we reviewed outcomes from mammography screening trials and from simulation models. A 2016 meta-analysis of mammography screening trials found a 33% reduction in breast cancer mortality with screening for women 60 to 69 years (risk ratio [RR], 0.67 [95% CI, 0.54-0.83]) and a 20% reduction in breast cancer mortality for women 70 to 74 year...

This study is the first to provide a direct link between this inflammation and plaque development - by way of IFITM3. Scientists know that the production of IFITM3 starts in response to activation of the immune system by invading viruses and bacteria. These observations, combined with the new findings that IFITM3 directly contributes to plaque formation, suggest that viral and bacterial infections could increase the risk of Alzheimer's disease development. Indeed, researchers found that the level of IFITM3 in human brain samples correlated with levels of certain viral infections as well as with gamma-secretase activ...

Abstract Late-stage functionalization (LSF) aids drug discovery efforts by introducing functional groups onto C-H bonds on pre-existing skeletons. We adopted the LSF strategy to synthesize analogues of the abundantly available triterpenoid, glycyrrhetinic acid (GA), by introducing aryl groups in the A-ring, expanding the A-ring and selectively activating one methyl group of the gem-dimethyl groups. Intriguingly, two compounds were found to preferentially accumulate in the mitochondrial compartment of MDA-MB-231 breast cancer cells, to cause depolarization of mitochondrial membrane potential and to induce antiproli...

AbstractPurposeTo present and discuss care domains (oncologic, cardiometabolic, aging, behavioral, environmental) for clinicians when approaching care for a breast cancer survivor at risk for developing breast cancer –related lymphedema (BCRL), as well as survivors who have been diagnosed with BCRL. Assessment using each domain aids in decision-making, yet also identifies barriers to pursuing personalized care for survivors with BCRL.Recent FindingsBCRL occurs from damage to the lymphatics during breast cancer treatment and occurs in approximately 20 to 40% of survivors. Prospective surveillance and early treatment f...

CONCLUSIONS: Our study established a unique model combining a radiomic signature and clinicopathological factors to predict tumor regression patterns prior to the initiation of NAC. The early prediction of type 2 regression offers the opportunity to modify preoperative treatments or aids in determining surgical options. PMID: 32759037 [PubMed - as supplied by publisher]

ndreas Stadlbauer The aim of this study was to investigate the potential of magnetic resonance imaging (MRI) for a non-invasive synergistic assessment of tumor microenvironment (TME) hypoxia and induced neovascularization for the identification of aggressive breast cancer. Fifty-three female patients with breast cancer underwent multiparametric breast MRI including quantitative blood-oxygen-level-dependent (qBOLD) imaging for hypoxia and vascular architecture mapping for neovascularization. Quantitative MRI biomarker maps of oxygen extraction fraction (OEF), metabolic rate of oxygen (MRO2), mitochondrial oxygen tension...

CONCLUSIONS: Older African American women are willing to engage in discussions about whether or not to continue breast cancer screening and found decision aids helpful. PMID: 32624238 [PubMed - as supplied by publisher]

Abstract Cell migration is a fundamental biological process involved in for example embryonic development, immune system and wound healing. Cell migration is also a key step in cancer metastasis and the human copper chaperone Atox1 was recently found to facilitate this process in breast cancer cells. To explore the role of the copper chaperone in other cell migration processes, we here investigated the putative involvement of an Atox1 homolog in Caenorhabditis elegans, CUC-1, in distal tip cell migration, which is a key process during the development of the C. elegans gonad. Using knock-out worms, in which the cuc...
