Merrimack Valley Elder Partners

As stated in the thesis project, "My project was to generate a series of issues forums for people over 60 in the Merrimack Valley. The mission of the group I worked with, Elder Partners of the Merrimack Valley, is to "organize and empower elders in the Merrimack Valley so that they can advocate for themselves to improve services and conditions". The process was to survey various elder providers (housing authorities, family service agencies, visiting nurse associations, Councils on Aging) to get a sense of what the elder network feels are important issues. The group then held a series of "community speak-outs" with elders throughout the Merrimack Valley. These were held in elder housings using peer facilitators. Issues generated from these two sources shaped the focus of the legislative forums. The first forum held was with state representatives, the next with national representative and a third with state representatives again (in a different district of the valley). The focus of these events was to gather together elder constituents with change makers. The underlying purpose of the project continues to be to create informed, empowered and organized advocates. My role in these activities has been to work as facilitator of the planning meetings, and provide administrative resources." (Library-derived description)Mansfield, J. H. (1995).

Exercise recommendations for people with bone metastases: Expert consensus for healthcare providers and clinical exercise professionals

Purpose: Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion. Methods: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement. Results: Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment–related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential. Conclusion: Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases

Genomics:GTL Bioenergy Research Centers White Paper

In his Advanced Energy Initiative announced in January 2006, President George W. Bush committed the nation to new efforts to develop alternative sources of energy to replace imported oil and fossil fuels. Developing cost-effective and energy-efficient methods of producing renewable alternative fuels such as cellulosic ethanol from biomass and solar-derived biofuels will require transformational breakthroughs in science and technology. Incremental improvements in current bioenergy production methods will not suffice. The Genomics:GTL Bioenergy Research Centers will be dedicated to fundamental research on microbe and plant systems with the goal of developing knowledge that will advance biotechnology-based strategies for biofuels production. The aim is to spur substantial progress toward cost-effective production of biologically based renewable energy sources. This document describes the rationale for the establishment of the centers and their objectives in light of the U.S. Department of Energy's mission and goals. Developing energy-efficient and cost-effective methods of producing alternative fuels such as cellulosic ethanol from biomass will require transformational breakthroughs in science and technology. Incremental improvements in current bioenergy-production methods will not suffice. The focus on microbes (for cellular mechanisms) and plants (for source biomass) fundamentally exploits capabilities well known to exist in the microbial world. Thus 'proof of concept' is not required, but considerable basic research into these capabilities remains an urgent priority. Several developments have converged in recent years to suggest that systems biology research into microbes and plants promises solutions that will overcome critical roadblocks on the path to cost-effective, large-scale production of cellulosic ethanol and other renewable energy from biomass. The ability to rapidly sequence the DNA of any organism is a critical part of these new capabilities, but it is only a first step. Other advances include the growing number of high-throughput techniques for protein production and characterization; a range of new instrumentation for observing proteins and other cell constituents; the rapid growth of commercially available reagents for protein production; a new generation of high-intensity light sources that provide precision imaging on the nanoscale and allow observation of molecular interactions in ultrafast time intervals; major advances in computational capability; and the continually increasing numbers of these instruments and technologies within the national laboratory infrastructure, at universities, and in private industry. All these developments expand our ability to elucidate mechanisms present in living cells, but much more remains to be done. The Centers are designed to accomplish GTL program objectives more rapidly, more effectively, and at reduced cost by concentrating appropriate technologies and scientific expertise, from genome sequence to an integrated systems understanding of the pathways and internal structures of microbes and plants most relevant to developing bioenergy compounds. The Centers will seek to understand the principles underlying the structural and functional design of selected microbial, plant, and molecular systems. This will be accomplished by building technological pathways linking the genome-determined components in an organism with bioenergy-relevant cellular systems that can be characterized sufficiently to generate realistic options for biofuel development. In addition, especially in addressing what are believed to be nearer-term approaches to renewable energy (e.g., producing cellulosic ethanol cost-effectively and energy-efficiently), the Center research team must understand in depth the current industrial-level roadblocks and bottlenecks (see section, GTL's Vision for Biological Energy Alternatives, below). For the Centers, and indeed the entire BER effort, to be successful, Center research must be integrated with individual investigator research, and coordination of activities, from DNA sequencing to high-throughput protein development and characterization

Exercise for individuals with bone metastases: A systematic review

Background Exercise has the potential to improve physical function and quality of life in individuals with bone metastases but is often avoided due to safety concerns. This systematic review summarizes the safety, feasibility and efficacy of exercise in controlled trials that include individuals with bone metastases. Methods MEDLINE, Embase, Pubmed, CINAHL, PEDro and CENTRAL databases were searched up to July 16, 2020. Results A total of 17 trials were included incorporating aerobic exercise, resistance exercise or soccer interventions. Few (n=4, 0.5%) serious adverse events were attributed to exercise participation, with none related to bone metastases. Mixed efficacy results were found, with exercise eliciting positive changes or no change. The majority of trials included an element of supervised exercise instruction (n=16, 94%) and were delivered by qualified exercise professionals (n=13, 76%). Conclusions Exercise appears safe and feasible for individuals with bone metastases when it includes an element of supervised exercise instruction

Optimization of percutaneous biopsy for diagnosis and pretreatment risk assessment of neuroblastoma

BackgroundImage- guided percutaneous core needle biopsy (PCNB) is increasingly utilized to diagnose solid tumors. The objective of this study is to determine whether PCNB is adequate for modern biologic characterization of neuroblastoma.ProcedureA multi- institutional retrospective study was performed by the Pediatric Surgical Oncology Research Collaborative on children with neuroblastoma at 12 institutions over a 3- year period. Data collected included demographics, clinical details, biopsy technique, complications, and adequacy of biopsies for cytogenetic markers utilized by the Children’s Oncology Group for risk stratification.ResultsA total of 243 children were identified with a diagnosis of neuroblastoma: 79 (32.5%) tumor excision at diagnosis, 94 (38.7%) open incisional biopsy (IB), and 70 (28.8%) PCNB. Compared to IB, there was no significant difference in ability to accurately obtain a primary diagnosis by PCNB (95.7% vs 98.9%, P = .314) or determine MYCN copy number (92.4% vs 97.8%, P = .111). The yield for loss of heterozygosity and tumor ploidy was lower with PCNB versus IB (56.1% vs 90.9%, P < .05; and 58.0% vs. 88.5%, P < .05). Complications did not differ between groups (2.9 % vs 3.3%, P = 1.000), though the PCNB group had fewer blood transfusions and lower opioid usage. Efficacy of PCNB was improved for loss of heterozygosity when a pediatric pathologist evaluated the fresh specimen for adequacy.ConclusionsPCNB is a less invasive alternative to open biopsy for primary diagnosis and MYCN oncogene status in patients with neuroblastoma. Our data suggest that PCNB could be optimized for complete genetic analysis by standardized protocols and real- time pathology assessment of specimen quality.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154667/1/pbc28153_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154667/2/pbc28153.pd

Tumour-draining axillary lymph nodes in patients with large and locally advanced breast cancers undergoing neoadjuvant chemotherapy (NAC): the crucial contribution of immune cells (effector, regulatory) and cytokines (TH1, TH2) to immune-mediated tumour cell death induced by NAC

Background The tumour microenvironment consists of malignant cells, stroma and immune cells. In women with large and locally advanced breast cancers (LLABCs) undergoing neoadjuvant chemotherapy (NAC), tumour-infiltrating lymphocytes (TILs), various subsets (effector, regulatory) and cytokines in the primary tumour play a key role in the induction of tumour cell death and a pathological complete response (pCR) with NAC. Their contribution to a pCR in nodal metastases, however, is poorly studied and was investigated. Methods Axillary lymph nodes (ALNs) (24 with and 9 without metastases) from women with LLABCs undergoing NAC were immunohistochemically assessed for TILs, T effector and regulatory cell subsets, NK cells and cytokine expression using labelled antibodies, employing established semi-quantitative methods. IBM SPSS statistical package (21v) was used. Non-parametric (paired and unpaired) statistical analyses were performed. Univariate and multivariate regression analyses were carried out to establish the prediction of a pCR and Spearman’s Correlation Coefficient was used to determine the correlation of immune cell infiltrates in ALN metastatic and primary breast tumours. Results In ALN metastases high levels of TILs, CD4+ and CD8+ T and CD56+ NK cells were significantly associated with pCRs.. Significantly higher levels of Tregs (FOXP3+, CTLA-4+) and CD56+ NK cells were documented in ALN metastases than in the corresponding primary breast tumours. CD8+ T and CD56+ NK cells showed a positive correlation between metastatic and primary tumours. A high % CD8+ and low % FOXP3+ T cells and high CD8+: FOXP3+ ratio in metastatic ALNs (tumour-free para-cortex) were associated with pCRs. Metastatic ALNs expressed high IL-10, low IL-2 and IFN-ϒ. Conclusions Our study has provided new data characterising the possible contribution of T effector and regulatory cells and NK cells and T helper1 and 2 cytokines to tumour cell death associated with NAC in ALNs

Synergistic combination of cytotoxic chemotherapy and cyclin-dependent kinase 4/6 inhibitors in biliary tract cancers

Background and aims: Biliary tract cancers (BTCs) are uncommon, but highly lethal, gastrointestinal malignancies. Gemcitabine/cisplatin is a standard-of-care systemic therapy, but has a modest impact on survival and harbors toxicities, including myelosuppression, nephropathy, neuropathy, and ototoxicity. Whereas BTCs are characterized by aberrations activating the cyclinD1/cyclin-dependent kinase (CDK)4/6/CDK inhibitor 2a/retinoblastoma pathway, clinical use of CDK4/6 inhibitors as monotherapy is limited by lack of validated biomarkers, diffident preclinical efficacy, and development of acquired drug resistance. Emerging studies have explored therapeutic strategies to enhance the antitumor efficacy of CDK4/6 inhibitors by the combination with chemotherapy regimens, but their mechanism of action remains elusive.Approach and results: Here, we report in vitro and in vivo synergy in BTC models, showing enhanced efficacy, reduced toxicity, and better survival with a combination comprising gemcitabine/cisplatin and CDK4/6 inhibitors. Furthermore, we demonstrated that abemaciclib monotherapy had only modest efficacy attributable to autophagy-induced resistance. Notably, triplet therapy was able to potentiate efficacy through elimination of the autophagic flux. Correspondingly, abemaciclib potentiated ribonucleotide reductase catalytic subunit M1 reduction, resulting in sensitization to gemcitabine.Conclusions: As such, these data provide robust preclinical mechanistic evidence of synergy between gemcitabine/cisplatin and CDK4/6 inhibitors and delineate a path forward for translation of these findings to preliminary clinical studies in advanced BTC patients.</p
