    Abstract A phase I study defined a tolerable combination of the ATR inhibitor ceralasertib with paclitaxel and responses were seen in patients with melanoma who had progressed on an immune checkpoint inhibitor. This combination warrants further exploration to determine the extent and molecular determinants of clinical activity.

    Abstract Breast cancer remains a highly prevalent disease with considerable inter- and intra-tumoral heterogeneity complicating prognostication and treatment decisions. The utilization and depth of genomic, transcriptomic and proteomic data for cancer has exploded over recent times and the addition of spatial context to this information, by understanding the correlating morphologic and spatial patterns of cells in tissue samples, has created an exciting frontier of research, histo-genomics. At the same time, deep learning (DL), a class of machine learning algorithms employing artificial neural networks, has rapidly progressed in the last decade with a confluence of technical developments - including the advent of modern graphic processing units (GPU), allowing efficient implementation of increasingly complex architectures at scale; advances in the theoretical and practical design of network architectures; and access to larger datasets for training - all leading to sweeping advances in image classification and object detection. In this review, we examine recent developments in the application of DL in breast cancer histology with particular emphasis of those producing biologic insights or novel biomarkers, spanning the extraction of genomic information to the use of stroma to predict cancer recurrence, with the aim of suggesting avenues for further advancing this exciting field.

    Abstract Following the successful renewal of its Cancer Center Support Grant (CCSG), leadership of the UCSF Helen Diller Comprehensive Cancer Center (HDFCCC) began a strategic planning process. The motivation was to think about where cancer research was going in the future; and with this vision to define a general scientific direction, mission, and priorities. HDFCCC Leadership began discussions about a new strategic plan in early 2018. From these meetings, the theme of "Cancer Research in 2030" arose: that is, what will cancer research look like in 2030? This forward-looking focus was intended to encourage creativity unconfined by a particular institutional structure or grant mechanism. Focusing on the science paved the way for an innovative, actionable, and motivating strategic planning process. Here, we describe the three-phase process, and the various groups involved across the HDFCCC and UCSF. We present the unique framework based on a cells-to-society model and an individual experience perspective, which led to the development of a logic model and ongoing implementation of tactics and tracking progress. We believe that sharing this process and its results will be of value to cancer centers and cancer researchers across the network of NCI comprehensive cancer centers, and cancer research centers in general.

    Abstract The International Malnutrition Task Force (IMTF) of the International Union of Nutritional Sciences was set up as an advocacy and capacity-building initiative in 2005 at a time when malnutrition contributed to 60% of deaths among children under-five, and when a reduction in under-five mortality by two thirds had been set as Millennium Development Goal 4. By forging partnerships through regional networks of academics, and linking with international agencies and non-governmental organizations, IMTF was able to increase awareness of the urgent need to address the prevention and treatment of child malnutrition. With modest funding, but a common purpose, partners initiated capacity building efforts to reduce high inpatient mortality rates among children admitted with severe malnutrition. In all regions, these initiatives catalysed scaling-up of the WHO 10-step treatment guidelines, resulting in substantial improvements in child survival. Many lessons were learned during this process including the importance of operational research, supervision and teamwork, and political commitment, and the potential of eLearning. By establishing alliances between academics, health professionals, policy makers, and national and international paediatric and nutrition societies through a Task Force, we suggest that similar benefits might accrue in other fields, including childhood cancer and school feeding.

    Abstract The genetic concept of synthetic lethality has now been validated clinically through the demonstrated efficacy of poly(ADP-ribose) polymerase (PARP) inhibitors for the treatment of cancers in individuals with germline loss-of-function mutations in either BRCA1 or BRCA2. Three different PARP inhibitors have now been approved for the treatment of patients with BRCA-mutant ovarian cancer and one for those with BRCA-mutant breast cancer; these agents have also shown promising results in patients with BRCA-mutant prostate cancer. Here, we describe a number of other synthetic lethal interactions that have been discovered in cancer. We discuss some of the underlying principles that might increase the likelihood of clinical efficacy and how new computational and experimental approaches are now facilitating the discovery and validation of synthetic lethal interactions. Finally, we make suggestions on possible future directions and challenges facing researchers in this field.

    Abstract The de novo design of small molecule-binding proteins has seen exciting recent progress; however, high-affinity binding and tunable specificity typically require laborious screening and optimization after computational design. We developed a computational procedure to design a protein that recognizes a common pharmacophore in a series of poly(ADP-ribose) polymerase-1 inhibitors. One of three designed proteins bound different inhibitors with affinities ranging from <5 nM to low micromolar. X-ray crystal structures confirmed the accuracy of the designed protein-drug interactions. Molecular dynamics simulations informed the role of water in binding. Binding free energy calculations performed directly on the designed models were in excellent agreement with the experimentally measured affinities. We conclude that de novo design of high-affinity small molecule-binding proteins with tuned interaction energies is feasible entirely from computation.

    Abstract The SUNshiners group includes people in the early stages of dementia with an interest in dementia activism and research. The group found that despite the growing awareness of invisible disabilities, there is very limited research into the pros and cons of the invisibility of dementia. Our paper explores the SUNshiners research which stemmed from varied individual experiences of disclosing diagnoses. The group designed and developed a short survey to explore what the public knew about dementia and what they thought about the invisibility of dementia. A mixture of open- and closed-ended questions were used to gain meaningful data. A total of 347 people completed the survey (315 online and 32 paper-based), which was then co-analysed. The findings suggest that the majority of the public felt that the invisibility of dementia was negative; that knowing someone had dementia when first meeting them would be beneficial; that people living with dementia should maintain the right to vote; and that people living with dementia do not automatically require a consistent, regular carer. Common themes from the open-ended answers included capacity, severity of dementia, and access to support. The findings support the disclosure of dementia diagnosis; however, more action is needed to tackle stigmatised views, particularly as the SUNshiners felt that people do not have enough dementia education to support a positive disclosure experience. They shared their experiences of the group and the project's benefits, but also the losses they have faced. Our paper aims to be as accessible as possible.
