This study assessed the lifetime health and economic consequences of an efficacious scalable community weight loss program for overweight and obese adults. We applied a state-transition Markov model to project lifetime economic outcome (US dollar) and the degree of disease averted as a result of a weight loss intervention, compared with no intervention, from a payer perspective. Effect sizes of the intervention on weight loss, by sex, race and ethnicity, and body mass index (BMI) of participants, were derived from a 12-month community program...

BACKGROUND: Current treatment for HER-2+ breast cancer includes chemotherapy and targeted HER-2 therapy with trastuzumab and/or pertuzumab. Evidence is lacking on the safety of breast reconstructive operations in these patients. We hypothesized that targeted HER-2 therapy was not associated with post-mastectomy reconstructive outcomes. STUDY DESIGN: Women receiving chemotherapy and post-mastectomy reconstruction at Duke University Medical Center from 2006 to 2016 were retrospectively identified...

BACKGROUND: The aim of this multicenter, retrospective, case-control study was to identify differences in risk factors of malignancy between men and women with type 2 diabetes. RESULTS: Among women the most prevalent malignancies were: breast and uterine cancers (35.6% and 14.4% respectively), while among men there were: colorectal and prostate cancers (24.5% and 13.3% respectively). In both gender metformin use was associated with lower cancer risk. Obesity and insulin treatment in dose-dependent and time-varying manner were associated with significantly increased risk of malignancy in females...

BACKGROUND: Breast-conserving surgery with adjuvant radiation therapy (BCT) has been established as safe oncologically. Oncoplastic breast surgery uses both oncologic and plastic surgery techniques for breast conservation to improve cosmetic outcomes. We evaluated the risk factors associated with complications after oncoplastic breast reduction. METHODS: A single-institution, institutional review board-approved, retrospective review of electronic medical records of female patients with breast cancer who underwent oncoplastic breast reduction from 2008 to 2014...

Metformin, a widely used drug for treating type-2 diabetes, has now been discovered to reduce cancer proliferation. However, further efforts are needed to design effective metformin delivery vehicles, instead of bare metformin. Here, we report a high-efficient transport nanostructure based on core-shell glyconanoparticles (GNPs), with gold as the core and dextran as the shell interspersed with metformin molecules. The dextran shell facilitates the entrance of GNPs into living cells, which allows the following release of metformin...

Purpose The association between long-acting insulin analogs and increased breast cancer risk is uncertain, particularly with the short follow-up in previous studies. We assessed this risk long term in women with type 2 diabetes. Methods A population-based cohort of women 40 years or older, all of whom were treated with long-acting (glargine, detemir) or neutral protamine Hagedorn (NPH) insulin between 2002 and 2012, was formed using the United Kingdom's Clinical Practice Research Datalink. Women were followed until February 2015 or breast cancer diagnosis...

PURPOSE: Dermatomyositis (DM) represents an auto-immune inflammatory myopathy. In this review, we analyzed the incidence of DM as a clinical manifestation highlighting the peculiar clinical and treatment characteristics of this disease when occurring in the context of different malignancies. METHODS: A systematic literature review was performed based on database search in PubMed/Medline and included English articles until December 2016. RESULTS: In up to 20% of cases DM appears as a paraneoplastic syndrome associated with multiple malignancies such as ovarian, breast, prostate, lung, nasopharyngeal and colorectal cancer, and non-Hodgkin lymphomas...

Reports suggest that metformin, a popular anti-diabetes drug, prevents breast cancer through various systemic effects, including insulin-like growth factor receptor (IGFR) regulation. Although the anti-cancer properties of metformin have been well-studied, reports on a more bioavailable/potent biguanide, phenformin, remain sparse. Phenformin exerts similar functional activity to metformin and has been reported to impede mammary carcinogenesis in rats. Since the effects of phenformin on specific breast cancer subtypes have not been fully explored, we used ErbB2-overexpressing breast cancer cell and animal models to test the anti-cancer potential of phenformin...

The widely prescribed diabetes medicine metformin has been reported to lower the risk of incident breast cancer, but it is unclear if it affects malignant progression after diagnosis. In this study, we conducted a retrospective cohort study using the linked Surveillance, Epidemiology and End-Results (SEER)-Medicare database. Women were included in the study if they were aged 66-80 years, newly diagnosed with stage I or II breast cancer, and enrolled in Medicare Parts A, B, and D during 2007-2011. Information on dispensed diabetes-related medications was obtained from Medicare Part D claims data...

BACKGROUND: Participants in clinical trials frequently fail to appreciate key differences between research and clinical care. This phenomenon, known as therapeutic misconception, undermines informed consent to clinical research, but to date there have been no effective interventions to reduce it and concerns have been expressed that to do so might impede recruitment. We determined whether a scientific reframing intervention reduces therapeutic misconception without significantly reducing willingness to participate in hypothetical clinical trials...
