OBJECTIVES: For women who have been diagnosed with unilateral breast cancer there is an increasing trend for them to request removal of the contralateral healthy breast, so called contralateral risk reducing mastectomy (CRRM). The current literature is only just beginning to identify patient-reported reasons for undergoing CRRM and associated patient reported outcomes. It is also unclear whether women at moderate/high risk of developing a subsequent primary contralateral breast cancer report similar outcomes to those considered to be at low/average risk...

Background: In respect of the principle of autonomy and the right of self-determination, obtaining an informed consent of potential participants before their inclusion in a study is a fundamental ethical obligation. The variations in national laws, regulations, and cultures contribute to complex informed consent documents for patients participating in clinical trials. Currently, only few ethics committees seem willing to address the complexity and the length of these documents and to request investigators and sponsors to revise them in a way to make them understandable for potential participants...

Research rationale: Studies on plant electrophysiology are mostly focused on specific traits of single cells. Inspired by the complexity of the signaling network in plants and by analogies with neurons in human brains, we have sought for evidences of high complexity in the electrical dynamics of plant signaling and a likely relation with environmental cues. Central methods: An EEG-like standard protocol was adopted for high-resolution measurements of the electrical signal in Glycine max seedlings. The signals were continuously recorded in the same plants before and after the osmotic stimuli with a -2 MPa mannitol solution...

In the late phase of the HIV virus cycle, the unspliced genomic RNA is exported to the cytoplasm for the necessary translation of the Gag and Gag-pol polyproteins. Three distinct translation initiation mechanisms ensuring Gag production have been described with little rationale for their multiplicity. The Gag-IRES has the singularity to be located within Gag ORF and to directly interact with ribosomal 40S. Aiming at elucidating the specificity and the relevance of this interaction, we probed HIV-1 Gag-IRES structure and developed an innovative integrative modelling strategy to take into account all the gathered information...

Importance: Uveal melanoma (UM) is an intraocular primary malignant neoplasm that often gives rise to metastatic disease for which there are no effective therapies. A substantial proportion of UMs express the cancer-testis antigen PRAME (preferentially expressed antigen in melanoma), which can potentially be targeted by adoptive T-cell therapy. Objective: To determine whether there may be a rationale for PRAME-directed T-cell therapy for metastatic UM. Design, Setting, and Participants: An experimental study using a retrospective cohort of 64 patients with UM (median follow-up, 62 months) was conducted from January 8, 2015, to November 20, 2016, at the Leiden University Medical Center...

Targeting the DNA damage response (DDR) is a new therapeutic approach in cancer that shows great promise for tumour selectivity. Key components of the DDR are the ataxia telangiectasia mutated and Rad3 related (ATR) and checkpoint kinase 1 (CHK1) kinases. This review article describes the role of ATR and its major downstream target, CHK1, in the DDR and why cancer cells are particularly reliant on the ATR-CHK1 pathway, providing the rationale for targeting these kinases, and validation of this hypothesis by genetic manipulation...

: Antihypertensive, lipid lowering, antidiabetic and antiplatelet treatments all substantially reduce the risk of cardiovascular morbid and fatal events. In real life, however, effective implementation of these treatments is rare, and thus their contribution to cardiovascular prevention is much less than it could be, based on research data. This article reviews the pros and cons of cardiovascular prevention by the polypill approach. It is argued that the high prevalence of individuals with a multifactorial risk profile provides a strong rationale for a therapeutic strategy based on the combination in a single tablet of drugs against different risk factors...

Renal cell carcinoma (RCC) affects > 60,000 people in the United States annually, and ~ 30% of RCC patients have multiple metastases at the time of diagnosis. Metastatic RCC (mRCC) is incurable, with a median survival time of only 18 months. Immune-based interventions (e.g., interferon (IFN) and interleukin (IL)-2) induce durable responses in a fraction of mRCC patients, and multikinase inhibitors (e.g., sunitinib or sorafenib) or anti-VEGF receptor monoclonal antibodies (mAb) are largely palliative, as complete remissions are rare...

A new strategy for CO2 capture is reported based on the synergistic effect of electrostatic in-plane and dispersive π-π stacking interactions of amide and indole with CO2. Density functional theory (DFT) illustrated that the amide group can have an increased ability to capture CO2 molecules that was just desorbed from an adjacent indole unit. We used this strategy to fabricate a microporous aerogel that exhibited superior CO2 capture performance in both dry and wet conditions. The proposed synergistic effect is expected to be a new rationale for the design of CO2 capture materials...

Soft nanoparticulate complexants are defined by a spatial confinement of reactive sites and electric charges inside their 3D body. In turn, their reactivity with metal ions differs significantly from that of simple molecular ligands. A revisited form of the Eigen mechanism recently elucidated the processes leading to metal/soft particle pair formation. Depending on e.g. particle size and metal ion nature, chemodynamics of nanoparticulate metal complexes is controlled by metal conductive diffusion to/from the particles, by intraparticulate complex formation/dissociation kinetics, or by both...

PURPOSE/OBJECTIVE: Chemo-radiotherapy is an established primary curative treatment for anal cancer, but clinically equal rationale for different target doses exists. If joint preferences (physician and patient) are used to determine acceptable tradeoffs in radiotherapy treatment planning, multiple dose plans must be simultaneously explored. We quantified the degree to which different toxicity priorities might be incorporated into treatment plan selection, to elucidate the feasible decision space for shared decision making in anal cancer radiotherapy...

Alternative course formats are gaining increasing attention in higher education. The literature provides a number of examples and studies of flipped classrooms in the medical sciences and liberal arts and sciences. However, fewer than five papers on flipped classes in graduate public health courses have been published, and none in health management. Because graduate public health education is competency based, it seems that a flipped approach with its applied nature would be an appropriate form of teaching public health courses...

This contribution in the "Best (but Oft-Forgotten) Practices" series considers mediation analysis. A mediator (sometimes referred to as an intermediate variable, surrogate endpoint, or intermediate endpoint) is a third variable that explains how or why ≥2 other variables relate in a putative causal pathway. The current article discusses mediation analysis with the ultimate intention of helping nutrition researchers to clarify the rationale for examining mediation, avoid common pitfalls when using the model, and conduct well-informed analyses that can contribute to improving causal inference in evaluations of underlying mechanisms of effects on nutrition-related behavioral and health outcomes...

Rationale: The relative actions and synergism between distinct myocardial-derived stem cell populations remains obscure. Ongoing debates regarding optimal cell population(s) for treatment of heart failure prompted implementation of a protocol for isolation of multiple stem cell populations from a single myocardial tissue sample to develop new insights for achieving myocardial regeneration. Objective: Establish a robust cardiac stem cell isolation and culture protocol to consistently generate three distinct stem cell populations from a single human heart biopsy...

BACKGROUND: HIV-associated neurocognitive disorders occur in nearly 50% of adults with HIV. Such disorders can interfere with everyday functioning such as driving and medication adherence. Therefore, cognitive interventions are needed to address such neurocognitive disorders as well as improve everyday functioning, especially as people age with HIV. OBJECTIVE: This article reports and discusses the overall rationale and development of speed of processing training, a computerized Internet cognitive training program, to improve this specific neurocognitive ability as well as everyday functioning and quality of life in adults aging with HIV...

Despite increasing amounts of experimental evidence depicting the involvement of non-coding RNAs in cancer, the study of BRAFV600E-regulated genes has thus far focused mainly on protein-coding ones. Here, we identify and study the microRNAs that BRAFV600E regulates through the ERK pathway.By performing small RNA sequencing on A375 melanoma cells and a vemurafenib-resistant clone that was taken as negative control, we discover miR-204 and miR-211 as the miRNAs most induced by vemurafenib. We also demonstrate that, although belonging to the same family, these two miRNAs have distinctive features...

Basal cell carcinomas (BCC) and squamous-cell carcinomas (SCC) are common malignancies in humans, caused by neoplastic transformation of keratinocytes of the basal or suprabasal layers of epidermis, respectively. Tumor-infiltrating lymphocytes (TILs) are frequently found in BCC and SCC, and functionally promote epithelial carcinogenesis. TILs secreting IL-22, in particular, participate to BCC and SCC growth by inducing keratinocyte proliferation and migration, as well as the expression of inflammatory, anti-apoptotic and pro-angiogenic genes...

BACKGROUND: Rates of glycemic control remain suboptimal nationwide. Medication intensification for diabetes can have undesirable side effects (weight gain, hypoglycemia), which offset the benefits of glycemic control. A Shared Medical Appointment (SMA) intervention for diabetes that emphasizes weight management could improve glycemic outcomes and reduce weight while simultaneously lowering diabetes medication needs, resulting in less hypoglycemia and better quality of life. We describe the rationale and design for a study evaluating a novel SMA intervention for diabetes that primarily emphasizes low-carbohydrate diet-focused weight management...

In the era of personalized medicine, the identification of targetable genetic alterations represented a major step forward in anticancer therapy. NTRK rearrangements represent the molecular driver of a subset of solid tumors, including 3% of non-small-cell lung cancers (NSCLCs). Preliminary data indicate that molecularly selected NSCLC patients harboring NTRK fusions derive an unprecedented clinical benefit from Trk-directed targeted therapies. The aim of this review is to describe the molecular biology of NTRK signaling pathway and to summarize the preclinical data on novel Trk inhibitors, touching upon the clinical development of these inhibitors for the treatment of advanced NSCLC, which have already shown encouraging anticancer activity and acceptable safety profile in early phase I clinical trials...
