    Full Text Available The 2013 Institute of Medicine report investigating cancer care concluded that the cancer care delivery system is in crisis due to an increased demand for care, increasing complexity of treatment, decreasing work force and rising costs. Engaging patients and incorporating evidence-based care into routine clinical practice are essential components of a high quality cancer delivery system. However, a gap currently exists between the identification of beneficial research findings and application in clinical practice. Implementation research strives to address this gap. In this review, we discuss key components of high quality implementation research. We then apply these concepts to a current cancer care delivery challenge in women’s health, specifically the implementation of a surgery decision aid for women newly diagnosed with breast cancer.

    Free-standing cancer centers (FSCC) represent a growing trend in cancer care delivery within community practice. The critical components to FSCC are multidisciplinary cancer care, a complete menu of direct care and support services, a commitment to clinical trials and clinical investigation, and a comprehensive program for quality assurance. The advantages of FSCC to the community, to hospital programs, to the practicing surgical, medical, and radiation oncologists, and to the third-party carriers, including health maintenance organizations, are detailed. The development of an FSCC depends on the resolution of issues of (a) competition (between hospitals, hospitals and physicians, therapeutic disciplines, regional comprehensive cancer centers and FSCCs) and (b) concerns about conflict of interest. The ideal model of FSCC may well be represented by the joint venture of community hospital(s) and the community oncologists.

    Current guidelines recommend all pediatric cancer survivors receive a survivor care plan (SCP) for optimal health management, yet clinical delivery of SCPs varies. We evaluated oncology providers' familiarity with and preferences for delivering SCPs to inform the implementation of a future SCP program at our institution. From November 2013 to April 2014, oncology providers from the Primary Children's Hospital in Salt Lake City, UT, completed a survey (n=41) and a 45-min focus group (n=18). Participants reported their familiarity with and training in SCP guidelines, opinions on SCPs, and barriers to delivering SCPs. As a secondary analysis, we examined differences in survey responses between physicians and nurses with Fisher's exact tests. Focus group transcripts and open-ended survey responses were content analyzed. Participants reported high familiarity with late effects of cancer treatment (87.8%) and follow-up care that cancer survivors should receive (82.5%). Few providers had delivered an SCP (oncologists 35.3% and nurses 5.0%; p=0.03). Barriers to providing SCPs included lack of knowledge (66.7%), SCP delivery is not expected in their clinic (53.9%), and no champion (48.7%). In qualitative comments, providers expressed that patient age variation complicated SCP delivery. Participants supported testing an SCP intervention program (95.1%) and felt this should be a team-based approach. Strategies for optimal delivery of SCPs are needed. Participants supported testing an SCP program to improve the quality of patient care. Team-based approaches, including nurses and physicians, that incorporate provider training on and support for SCP delivery are needed to improve pediatric cancer care.

    Palliative care and rehabilitation practitioners are important collaborative referral sources for each other who can work together to improve the lives of cancer patients, survivors, and caregivers by improving both quality of care and quality of life. Cancer rehabilitation and palliative care involve the delivery of important but underutilized medical services to oncology patients by interdisciplinary teams. These subspecialties are similar in many respects, including their focus on improving cancer-related symptoms or cancer treatment-related side effects, improving health-related quality of life, lessening caregiver burden, and valuing patient-centered care and shared decision-making. They also aim to improve healthcare efficiencies and minimize costs by means such as reducing hospital lengths of stay and unanticipated readmissions. Although their goals are often aligned, different specialized skills and approaches are used in the delivery of care. For example, while each specialty prioritizes goal-concordant care through identification of patient and family preferences and values, palliative care teams typically focus extensively on using patient and family communication to determine their goals of care, while also tending to comfort issues such as symptom management and spiritual concerns. Rehabilitation clinicians may tend to focus more specifically on functional issues such as identifying and treating deficits in physical, psychological, or cognitive impairments and any resulting disability and negative impact on quality of life. Additionally, although palliative care and rehabilitation practitioners are trained to diagnose and treat medically complex patients, rehabilitation clinicians also treat many patients with a single impairment and a low symptom burden. In these cases, the goal is often cure of the underlying neurologic or musculoskeletal condition. This report defines and describes cancer rehabilitation and palliative care, delineates their

    Virtually all cases of invasive cervical cancer are associated with infection by high-risk strains of human papilloma virus. Effective primary and secondary prevention programs, as well as effective treatment for early-stage invasive cancer have dramatically reduced the burden of cervical cancer in high-income countries; 85% of the mortality from cervical cancer now occurs in low- and middle-income countries. This article provides an overview of challenges to cervical cancer care in sub-Saharan Africa (SSA) and identifies areas for programmatic development to meet the global development goal to reduce cancer-related mortality. Advanced stage at presentation and gaps in prevention, screening, diagnostic, and treatment capacities contribute to reduced cervical cancer survival. Cost-effective cervical cancer screening strategies implemented in low resource settings can reduce cervical cancer mortality. Patient- and system-based barriers need to be addressed as part of any cervical cancer control program. Limited human capacity and infrastructure in SSA are major barriers to comprehensive cervical cancer care. Management of early-stage, locally advanced or metastatic cervical cancer involves multispecialty care, including gynecology oncology, medical oncology, radiology, pathology, radiation oncology, and palliative care. Investment in cervical cancer care programs in low- and middle-income countries will need to include effective recruitment programs to engage women in the community to access cancer screening and diagnosis services. Though cervical cancer is a preventable and treatable cancer, the challenges to cervical control in SSA are great and will require a broadly integrated and sustained effort by multiple stakeholders before meaningful progress can be achieved.

    Full Text Available Abstract Background In this article, we describe the National Cancer Institute (NCI Community Cancer Centers Program (NCCCP pilot and the evaluation designed to assess its role, function, and relevance to the NCI's research mission. In doing so, we describe the evolution of and rationale for the NCCCP concept, participating sites' characteristics, its multi-faceted aims to enhance clinical research and quality of care in community settings, and the role of strategic partnerships, both within and outside of the NCCCP network, in achieving program objectives. Discussion The evaluation of the NCCCP is conceptualized as a mixed method multi-layered assessment of organizational innovation and performance which includes mapping the evolution of site development as a means of understanding the inter- and intra-organizational change in the pilot, and the application of specific evaluation metrics for assessing the implementation, operations, and performance of the NCCCP pilot. The assessment of the cost of the pilot as an additional means of informing the longer-term feasibility and sustainability of the program is also discussed. Summary The NCCCP is a major systems-level set of organizational innovations to enhance clinical research and care delivery in diverse communities across the United States. Assessment of the extent to which the program achieves its aims will depend on a full understanding of how individual, organizational, and environmental factors align (or fail to align to achieve these improvements, and at what cost.

High incidence and survival rates for prostate cancer have resulted in a large and growing population of long-term prostate cancer survivors. Long-term follow-up guidelines have only recently been developed to inform approaches to this phase of care for the prostate cancer population. Methods: A PubMed search of English literature through August 2014 was performed. Articles were retrieved and reviewed to confirm their relevance. Patient-reported measures that were used in studies of long-term prostate cancer survivors (ie, at least 2 years posttreatment were reviewed and included in the review. Results: A total of 343 abstracts were initially identified from the database search. After abstract review, 105 full-text articles were reviewed of which seven met inclusion criteria. An additional 22 articles were identified from the references of the included articles, and 29 were retained. From the 29 articles, 68 patient-reported outcome measures were identified. The majority (75% were multi-item scales that had been previously validated in existing literature. We identified four main areas of assessment: 1 physical health; 2 quality of life – general, physical, and psychosocial; 3 health promotion – physical activity, diet, and tobacco cessation; and 4 care quality outcomes. Conclusion: There are a number of well-validated measures that assess patient-reported outcomes that document key aspects of long-term follow-up with respect to patient symptoms and quality of life.

With population aging and increases in survival, the number of CRC survivors is projected to rise dramatically. The time following initial treatment is often described as a period of transition from intensive hospital-based care back into “regular life.” This review provides an overview of recommended follow-up care for people with CRC who have been treated with curative intent, as well as exploring the current state of the research that underpins these guidelines. For patients, key concerns following treatment include the development of recurrent and new cancers, late and long-term effects of cancer and treatment, and the interplay of these factors with daily function and general health. For physicians, survivorship care plans can be a tool for coordinating the surveillance, intervention, and prevention of these key patient concerns. Though much of the research in cancer survivorship to date has focused on surveillance for recurrent disease, many national guidelines differ in their conclusions about the frequency and timing of follow-up tests. Most CRC guidelines refer only briefly to the management of side effects, despite reports that many patients have a range of ongoing physiological, psychosocial, and functional needs. Guidance for surveillance and intervention is often limited by a small number of heterogeneous trials conducted in this patient group. However, recently released survivorship guidelines emphasize the potential for the effectiveness of

    The purpose of the study was to obtain an in-depth understanding of the perceptions of advanced practice providers (APPs) with respect to their current roles in the context of the transition to a new cancer care delivery system, as well as factors that may influence their ability to practice at their level of training and education. Five focus groups were conducted with 15 APPs (11 nurse practitioners, 4 physician assistants). Data were collected by a recorder at each focus group. Four investigators reviewed the data from each group for accuracy and to generate an initial set of codes. Codes were compared across reviewers until consensus was reached and final themes were agreed upon. The mean age of the participants was 43.5 years (range: 27 to 63 years). The APPs practiced for an average of 11 years (range: 1 to 27 years), with a mean of 6.5 years in oncology (range: 1 to 11 years). Six themes were generated from the data related to the APP role during the transition to a new oncology care system: experiencing role tension, facing communication barriers, seeking mentorship, dealing with fragmented care, recognizing the need for professional growth, and navigating a new system. Our findings may inform administrators about the role of the APP in quality care delivery. These findings may empower APPs to practice to the full scope of their training and educational preparation, thereby facilitating their goals for professional development. PMID:25031925

    As reimbursement transitions from a volume-based to a value-based system, innovation in health care delivery will be needed. The process of innovation begins with framing the problem that needs to be solved along with the strategic vision that has to be achieved. Similar to scientific testing, a hypothesis is generated for a new solution to a problem. Innovation requires conducting a disciplined form of experimentation and then learning from the process. This manuscript will discuss the different types of innovation, and the key steps necessary for successful innovation in the health care field.

    Hematopoietic cell transplantation (HCT) is an important and complex treatment modality for a variety of hematologic malignancies and some solid tumors. Although outcomes of patients who have undergone HCT and require care in intensive care units (ICUs) have improved over time, mortality rates remain high and there are significant associated costs. Lack of a team-based approach to care, especially during critical illness, is detrimental to patient autonomy and satisfaction, and to team morale, ultimately leading to poor quality of care. In this manuscript, we describe the case of a patient who had undergone HCT and was in the ICU setting, where inconsistent team interaction among the various stakeholders delivering care resulted in a lack of shared goals and poor outcomes. Team cognition is cognitive processing at the team level through interactions among team members and is reflected in dynamic communication and coordination behaviors. Although the patient received multidisciplinary care as needed in a medically complicated case, a lack of team cognition and, particularly, inconsistent communication among the dynamic teams caring for the patient, led to mixed messages being delivered with high-cost implications for the health-care system and the family. This article highlights concepts and recommendations that begin a necessary in-depth assessment of implications for clinical care and initiate a research agenda that examines the effects of team cognition on HCT teams, and, more generally, critical care of the patient with cancer.

    Patient navigation is emerging as a standard in breast cancer care delivery, yet multi-site data on the impact of navigation at reducing delays along the continuum of care are lacking. The purpose of this study was to determine the effect of navigation on reaching diagnostic resolution at specific time points after an abnormal breast cancer screening test among a national sample. A prospective meta-analysis estimated the adjusted odds of achieving timely diagnostic resolution at 60, 180, and 365 days. Exploratory analyses were conducted on the pooled sample to identify which groups had the most benefit from navigation. Clinics from six medical centers serving vulnerable populations participated in the Patient Navigation Research Program. Women with an abnormal breast cancer screening test between 2007 and 2009 were included and received the patient navigation intervention or usual care. Patient navigators worked with patients and their care providers to address patient-specific barriers to care to prevent delays in diagnosis. A total of 4675 participants included predominantly racial/ethnic minorities (74 %) with public insurance (40 %) or no insurance (31 %). At 60 days and 180 days, there was no statistically significant effect of navigation on achieving timely diagnostic care, but a benefit of navigation was seen at 365 days (aOR 2.12, CI 1.36-3.29). We found an equal benefit of navigation across all groups, regardless of race/ethnicity, language, insurance status, and type of screening abnormality. Patient navigation resulted in more timely diagnostic resolution at 365 days among a diverse group of minority, low-income women with breast cancer screening abnormalities.

    Initiatives to address the unmet needs of those facing both poverty and serious illness have expanded significantly over the past decade. But many of them are designed in an ad-hoc manner to address one health problem among many; they are too rarely assessed; best practices spread slowly. When assessments of delivery do occur, they are often narrow studies of the cost-effectiveness of a single intervention rather than the complex set of them required to deliver value to patients and their families. We propose a framework for global health-care delivery and evaluation by considering efforts to introduce HIV/AIDS care to resource-poor settings. The framework introduces the notion of care delivery value chains that apply a systems-level analysis to the complex processes and interventions that must occur, across a health-care system and over time, to deliver high-value care for patients with HIV/AIDS and cooccurring conditions, from tuberculosis to malnutrition. To deliver value, vertical or stand-alone projects must be integrated into shared delivery infrastructure so that personnel and facilities are used wisely and economies of scale reaped. Two other integrative processes are necessary for delivering and assessing value in global health: one is the alignment of delivery with local context by incorporating knowledge of both barriers to good outcomes (from poor nutrition to a lack of water and sanitation) and broader social and economic determinants of health and wellbeing (jobs, housing, physical infrastructure). The second is the use of effective investments in care delivery to promote equitable economic development, especially for those struggling against poverty and high burdens of disease. We close by reporting our own shared experience of seeking to move towards a science of delivery by harnessing research and training to understand and improve care delivery.

    Full Text Available Understanding the biology of cancer at the cellular and molecular levels, and the application of such knowledge to the patient, has opened new opportunities and uncovered new obstacles to quality cancer care delivery. Benefits include our ability to now understand that many, if not, most cancers are not one-size-fits-all. Cancers are a variety of diseases for which intervention may be very different. This approach is beginning to bear fruit in gynecologic cancers where we are investigating therapeutic optimization at a more focused level, that while not yet precision care, is perhaps much improved. Obstacles to quality care for patients come from many directions. These include incomplete understanding of the role of the mutant proteins in the cancers, the narrow spectrum of agents, and broader mutational profiles in solid tumors, and the sometimes overzealous application of the findings of genetic testing. This has been further compromised by the unbridled use of social media by all stakeholders in cancer care often without scientific qualification, where anecdote sometimes masquerades as fact. The only current remedy is to wave the flag of caution, encourage all patients who undergo genetic testing, either germline or somatic, to do so with the oversight of genetic counselors and physician scientists knowledgeable in the pathways involved. This aspiration is accomplished with well designed clinical trials that inform next steps in this complex and ever evolving process.

  20. Redesigning ambulatory care business processes supporting clinical care delivery.

    1997-04-01

    The first step in redesigning the health care delivery process for ambulatory care begins with the patient and the business processes that support the patient. Patient-related business processes include patient access, service documentation, billing, follow-up, collection, and payment. Access is the portal to the clinical delivery and care management process. Service documentation, charge capture, and payment and collection are supporting processes to care delivery. Realigned provider networks now demand realigned patient business services to provide their members/customers/patients with improved service delivery at less cost. Purchaser mandates for cost containment, health maintenance, and enhanced quality of care have created an environment where every aspect of the delivery system, especially ambulatory care, is being judged. Business processes supporting the outpatient are therefore being reexamined for better efficiency and customer satisfaction. Many health care systems have made major investments in their ambulatory care environment, but have pursued traditional supporting business practices--such as multiple access points, lack of integrated patient appointment scheduling and registration, and multiple patient bills. These are areas that are appropriate for redesign efforts--all with the customer's needs and convenience in mind. Similarly, setting unrealistic expectations, underestimating the effort required, and ignoring the human elements of a patient-focused business service redesign effort can sabotage the very sound reasons for executing such an endeavor. Pitfalls can be avoided if a structured methodology, coupled with a change management process, are employed. Deloitte & Touche Consulting Group has been involved in several major efforts, all with ambulatory care settings to assist with the redesign of their business practices to consider the patient as the driver, instead of the institution providing the care.

    The independent Office of the Actuary for CMS certified that the Pioneer ACO model has met the stringent criteria for expansion to a larger population. Significant savings have accrued and quality targets have been met, so the program as a whole appears to be working. Ironically, 13 of the initial 32 enrollees have left. We attribute this to the design of the ACO models which inadequately support efficient care delivery. Using Bellin-ThedaCare Healthcare Partners as an example, we will focus on correctible flaws in four core elements of the ACO payment model: finance spending and targets, attribution, and quality performance.

    Full Text Available Abstract Background The health care delivery system in the United States is facing cost and quality pressures that will require fundamental changes to remain viable. The optimal structures of the relationships between the hospital, medical school, and physicians have not been determined but are likely to have a large impact on the future of healthcare delivery. Because it is generally agreed that academic medical centers will play a role in the sustainability of this future system, a fundamental understanding of the relative contributions of the stakeholders is important as well as creativity in developing novel strategies to achieve a shared vision. Discussion Core competencies of each of the stakeholders (the hospital, the medical school and the physicians must complement the others and should act synergistically. At the same time, the stakeholders should determine the common core values and should be able to make a meaningful contribution to the delivery of health care. Summary Health care needs to achieve higher quality and lower cost. Therefore, in order for physicians, medical schools, and hospitals to serve the needs of society in a gratifying way, there will need to be change. There needs to be more scientific and social advances. It is obvious that there is a real and urgent need for relationship building among the professionals whose duty it is to provide these services.

    There is increasing enthusiasm for genomics and its promise in advancing personalized medicine. Genomic information has been used to personalize health care for decades, spanning the fields of cardiovascular disease, infectious disease, endocrinology, metabolic medicine, and hematology. However, oncology has often been the first test bed for the clinical translation of genomics for diagnostic, prognostic, and therapeutic applications. Notable hereditary cancer examples include testing for mutations in BRCA1 or BRCA2 in unaffected women to identify those at significantly elevated risk for developing breast and ovarian cancers, and screening patients with newly diagnosed colorectal cancer for mutations in 4 mismatch repair genes to reduce morbidity and mortality in their relatives. Somatic genomic testing is also increasingly used in oncology, with gene expression profiling of breast tumors and EGFR testing to predict treatment response representing commonly used examples. Health technology assessment provides a rigorous means to inform clinical and policy decision-making through systematic assessment of the evidentiary base, along with precepts of clinical effectiveness, cost-effectiveness, and consideration of risks and benefits for health care delivery and society. Although this evaluation is a fundamental step in the translation of any new therapeutic, procedure, or diagnostic test into clinical care, emerging developments may threaten this standard. These include "direct to consumer" genomic risk assessment services and the challenges posed by incidental results generated from next-generation sequencing (NGS) technologies. This article presents a review of the evidentiary standards and knowledge base supporting the translation of key cancer genomic technologies along the continuum of validity, utility, cost-effectiveness, health service impacts, and ethical and societal issues, and offers future research considerations to guide the responsible introduction of

    Full Text Available Objectives: Increasing demands on primary care providers have created a need for systems-level initiatives to improve primary care delivery. The purpose of this article is to describe and present outcomes for 2 such initiatives: the Pennsylvania Academy of Family Physicians’ Residency Program Collaborative (RPC and the St Johnsbury Vermont Community Health Team (CHT. Methods: Researchers conducted case studies of the initiatives using mixed methods, including secondary analysis of program and electronic health record data, systematic document review, and interviews. Results: The RPC is a learning collaborative that teaches quality improvement and patient centeredness to primary care providers, residents, clinical support staff, and administrative staff in residency programs. Results show that participation in a higher number of live learning sessions resulted in a significant increase in patient-centered medical home recognition attainment and significant improvements in performance in diabetic process measures including eye examinations (14.3%, P = .004, eye referrals (13.82%, P = .013, foot examinations (15.73%, P = .003, smoking cessation (15.83%, P = .012, and self-management goals (25.45%, P = .001. As a community-clinical linkages model, CHT involves primary care practices, community health workers (CHWs, and community partners. Results suggest that CHT members successfully work together to coordinate comprehensive care for the individuals they serve. Further, individuals exposed to CHWs experienced increased stability in access to health insurance (P = .001 and prescription drugs (P = .000 and the need for health education counseling (P = .000. Conclusion: Findings from this study indicate that these 2 system-level strategies have the promise to improve primary care delivery. Additional research can determine the extent to which these strategies can improve other health outcomes.

The frustrating reality is that as our knowledge of how to diagnose and treat medical conditions has continued to advance, the system to deliver that care has remained in an embryonic stage. This has resulted in millions of people being denied their most basic health care needs. Telemedicine utilizes an interactive video system integrated with biomedical telemetry that allows a physician at a base station specialty medical complex or teaching hospital to examine and treat a patient at multiple satellite locations, such as rural hospitals, ambulatory health centers, correctional institutions, facilities caring for the elderly, community hospital emergency departments, or international health facilities. Based on the interactive nature of the system design, the consulting physician at the base station can do a complete history and physical examination, as if the patient at the satellite site was sitting in the physician's office. This system is described.

    Cell-penetrating peptides (CPPs) can be used for intracellular delivery of a broad variety of cargoes, including various nanoparticulate pharmaceutical carriers. However, the cationic nature of all CPP sequences, and thus lack of cell specificity, limits their in vivo use for drug delivery applications. Here, we have devised and tested a strategy for site-specific delivery of dyes and drugs into cancer cells by using polymers bearing a light activated caged CPP (cCPP). The positive charge of Lys residues on the minimum sequence of the CPP penetratin ((52)RRMKWKK(58)) was masked with photo-cleavable groups to minimize non-specific adsorption and cellular uptake. Once illuminated by UV light, these protecting groups were cleaved, the positively charged CPP regained its activity and facilitated rapid intracellular delivery of the polymer-dye or polymer-drug conjugates into cancer cells. We have found that a 10-min light illumination time was sufficient to enhance the penetration of the polymer-CPP conjugates bearing the proapoptotic peptide, (D)(KLAKLAK)(2), into 80% of the target cells, and to promote a 'switch' like cytotoxic activity resulting a shift from 100% to 10% in cell viability after 2 h. This report provides an example for tumor targeting by means of light activation of cell-penetrating peptides for intracellular drug delivery.

    Clinical research centers that support hypothesis-driven investigation have long been a feature of academic medical centers but facilities in which clinical care delivery can be systematically assessed and evaluated have heretofore been nonexistent. The Institute of Medicine report "Crossing the Quality Chasm" identified six core attributes of an ideal care delivery system that in turn relied heavily on system redesign. Although manufacturing and service industries have leveraged modern design principles in new product development, healthcare has lagged behind. In this article, we describe a methodology utilized by our facility to study the clinical care delivery system that incorporates modern design principles.

    Responding to growing concerns regarding the safety, quality, and efficacy of cancer care in the United States, the Institute of Medicine (IOM) of the National Academy of Sciences commissioned a comprehensive review of cancer care delivery in the US health care system in the late 1990s. The National Cancer Policy Board (NCPB), a 20-member board with broad representation, performed this review. In its review, the NCPB focused on the state of cancer care delivery at that time, its shortcomings, and ways to measure and improve the quality of cancer care. The NCPB described an ideal cancer care system in which patients would have equitable access to coordinated, guideline-based care and novel therapies throughout the course of their disease. In 1999, the IOM published the results of this review in its influential report, Ensuring Quality Cancer Care. The report outlined 10 recommendations, which, when implemented, would: 1) improve the quality of cancer care, 2) increase the current understanding of quality cancer care, and 3) reduce or eliminate access barriers to quality cancer care. Despite the fervor generated by this report, there are lingering doubts regarding the safety and quality of cancer care in the United States today. Increased awareness of medical errors and barriers to quality care, coupled with escalating health care costs, has prompted national efforts to reform the health care system. These efforts by health care providers and policymakers should bridge the gap between the ideal state described in Ensuring Quality Cancer Care and the current state of cancer care in the United States.

    Recently, nanomedicine has received increasing attention for its ability to improve the efficacy of cancer therapeutics. Nanosized polymer therapeutic agents offer the advantage of prolonged circulation in the blood stream, targeting to specific sites, improved efficacy and reduced side effects. In this way, local, controlled delivery of the drug will be achieved with the advantage of a high concentration of drug release at the target site while keeping the systemic concentration of the drug low, thus reducing side effects due to bioaccumulation. Various drug delivery systems such as nanoparticles, liposomes, microparticles and implants have been demonstrated to significantly enhance the preventive/therapeutic efficacy of many drugs by increasing their bioavailability and targetability. As these carriers significantly increase the therapeutic effect of drugs, their administration would become less cost effective in the near future. The purpose of our research work is to develop a delivery system for breast cancer cells using a microvector of drugs. These results highlight the potential uses of these responsive platforms suited for biomedical and pharmaceutical applications. At the request of all authors of the paper an updated version was published on 12 July 2016. The manuscript was prepared and submitted without Dr. Francesca Cavalieri's contribution and her name was added without her consent.

  18. Vascular permeability and drug delivery in cancers

    Directory of Open Access Journals (Sweden)

    Sandy eAzzi

    2013-08-01

    Full Text Available The endothelial barrier strictly maintains vascular and tissue homeostasis, and therefore modulates many physiological processes such as angiogenesis, immune responses, and dynamic exchanges throughout organs. Consequently, alteration of this finely tuned function may have devastating consequences for the organism. This is particularly obvious in cancers, where a disorganized and leaky blood vessel network irrigates solid tumors. In this context, vascular permeability drives tumor-induced angiogenesis, blood flow disturbances, inflammatory cell infiltration, and tumor cell extravasation. This can directly restrain the efficacy of conventional therapies by limiting intravenous drug delivery. Indeed, for more effective anti-angiogenic therapies, it is now accepted that not only should excessive angiogenesis be alleviated, but also that the tumor vasculature needs to be normalized. Recovery of normal state vasculature requires diminishing hyperpermeability, increasing pericyte coverage, and restoring the basement membrane, to subsequently reduce hypoxia and interstitial fluid pressure. In this review, we will introduce how vascular permeability accompanies tumor progression and, as a collateral damage, impacts on efficient drug delivery. The molecular mechanisms involved in tumor-driven vascular permeability will next be detailed, with a particular focus on the main factors produced by tumor cells, especially the emblematic vascular endothelial growth factor (VEGF. Finally, new perspectives in cancer therapy will be presented, centered on the use of anti-permeability factors and normalization agents.

    2015-11-15

    The Global Health Delivery (GHD) framework (Farmer, Kim, and Porter, Lancet 2013;382:1060-69) allows for the analysis of health care delivery systems along four axes: a care delivery value chain that incorporates prevention, diagnosis, and treatment of a medical condition; shared delivery infrastructure that integrates care within existing healthcare delivery systems; alignment of care delivery with local context; and generation of economic growth and social development through the health care delivery system. Here, we apply the GHD framework to epilepsy care in rural regions of low- and middle-income countries (LMIC) where there are few or no neurologists.

  1. Controlled drug delivery systems towards new frontiers in patient care

    Rossi, Filippo; Masi, Maurizio

    2016-01-01

    This book offers a state-of-the-art overview of controlled drug delivery systems, covering the most important innovative applications. The principles of controlled drug release and the mechanisms involved in controlled release are clearly explained. The various existing polymeric drug delivery systems are reviewed, and new frontiers in material design are examined in detail, covering a wide range of polymer modification techniques. The concluding chapter is a case study focusing on use of a drug-eluting stent. The book is designed to provide the reader with a complete understanding of the mechanisms and design of controlled drug delivery systems, and to this end includes numerous step-by-step tutorials. It illustrates how chemical engineers can advance medical care by designing polymeric delivery systems that achieve either temporal or spatial control of drug delivery and thus ensure more effective therapy that eliminates the potential for both under-and overdosing.

In this context, the purpose of the present study was to analyze the influence of spirituality in childhood cancer care, involving biopsychosocial aspects of the child, the family, and the health care team facing the disease. To accomplish this purpose, a nonsystematic review of literature of articles on national and international electronic databases (Scientific Electronic Library Online [SciELO], PubMed, and Latin American and Caribbean Health Sciences Literature [LILACS] was conducted using the search terms “spirituality,” “child psychology,” “child,” and “cancer,” as well as on other available resources. After the search, 20 articles met the eligibility criteria and were included in the final sample. Our review showed that the relation between spirituality and health has lately become a subject of growing interest among researchers, as a positive influence of spirituality in the people's welfare was noted. Studies that were retrieved using the mentioned search strategy in electronic databases, independently assessed by the authors according to the systematic review, showed that spirituality emerges as a driving force that helps pediatric patients and their families in coping with cancer.

    The patient experience has moved to the forefront of health care-delivery research. The University of Texas MD Anderson Cancer Center Department of Diagnostic Radiology began collaborating in 2011 with the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management, and in 2013 with the University of Nevada, Las Vegas, William F. Harrah College of Hotel Administration, to explore the application of service science to improving the patient experience. A collaborative pilot study was undertaken by these 3 institutions to identify and rank the specific needs and expectations of patients undergoing imaging procedures in the MD Anderson Department of Diagnostic Radiology. We first conducted interviews with patients, providers, and staff to identify factors perceived to affect the patient experience. Next, to confirm these factors and determine their relative importance, we surveyed more than 6,000 patients by e-mail. All factors considered important in the interviews were confirmed as important in the surveys. The surveys showed that the most important factors were acknowledgment of the patient's concerns, being treated with respect, and being treated like a person, not a "number"; these factors were more important than privacy, short waiting times, being able to meet with a radiologist, and being approached by a staff member versus having one's name called out in the waiting room. Our work shows that it is possible to identify and rank factors affecting patient satisfaction using techniques employed by the hospitality industry. Such factors can be used to measure and improve the patient experience.

    1996-01-01

    Health care reengineering is a powerful methodology that helps organizations reorder priorities, provide more cost-effective care, and increase value to customers. It should be driven by what the customer wants and what the market needs. Systemwide reengineering integrates three levels of activity: managing community and health plan partnerships; consolidating overlapping delivery system functions among participating providers and vendors; and redesigning administrative functions, clinical services, and caregiving programs to improve health status. Reengineering is not a panacea; it is a critical core competency and requisite skill for health care organizations if they are to succeed under managed care in the future.

    Post-treatment cancer care is often fragmented and of suboptimal quality. We explored factors that may affect cancer survivors' post-treatment care coordination, including oncologists' use of electronic technologies such as e-mail and integrated electronic health records (EHRs) to communicate with primary care physicians (PCPs). We used data from a survey (357 respondents; participation rate 52.9%) conducted in 2012-2013 among medical oncologists caring for patients in a large US study of cancer care delivery and outcomes. Oncologists reported their frequency and mode of communication with PCPs, and role in providing post-treatment care. Seventy-five per cent said that they directly communicated with PCPs about post-treatment status and care recommendations for all/most patients. Among those directly communicating with PCPs, 70% always/usually used written correspondence, while 36% always/usually used integrated EHRs; telephone and e-mail were less used. Eighty per cent reported co-managing with PCPs at least one post-treatment general medical care need. In multivariate-adjusted analyses, neither communication mode nor intensity were associated with co-managing survivors' care. Oncologists' reliance on written correspondence to communicate with PCPs may be a barrier to care coordination. We discuss new research directions for enhancing communication and care coordination between oncologists and PCPs, and to better meet the needs of cancer survivors post-treatment.

    Being diagnosed with a life-threatening disease such as cancer and undergoing treatment can cause unwanted distress and interferes with quality of life. Uncontrolled stress can have a negative effect on a number of biological systems and processes leading to negative health outcomes. While some distress is normal, it is not benign and must be addressed, as failure to do so may compromise health and QOL outcomes. We present the evidence for the role of stress in cancer biology and mechanisms demonstrating how distress is associated with worse clinical outcomes. The National Comprehensive Cancer Network states that all patients be screened with the single-item distress thermometer and to also indicate the source of distress and to get appropriate referral. In addition to the many conventional approaches for managing distress from the fields of psychology and psychiatry, many patients are seeking strategies to manage their distress that are outside conventional medicine such as mind-body techniques. Mind-body techniques such as meditation, yoga, tai chi, and qigong have been found to lower distress and lead to improvements in different aspects of quality of life. It is essential that the standard of care in oncology include distress screening and the delivery of different techniques to help patients manage the psychosocial challenges of diagnosis and treatment of cancer.

    Full Text Available Abstract Background Delivery by a skilled birth attendant (SBA in a hospital is advocated to improve maternal health; however, hospital expenses for delivery care services are a concern for women and their families, particularly for women who pay out-of-pocket. Although health insurance is now implemented in Lao PDR, it is not universal throughout the country. The objectives of this study are to estimate the total health care expenses for vaginal delivery and caesarean section, to determine the association between health insurance and family income with health care expenditure and assess the effect of health insurance from the perspectives of the women and the skilled birth attendants (SBAs in Lao PDR. Methods A cross-sectional study was carried out in two provincial hospitals in Lao PDR, from June to October 2010. Face to face interviews of 581 women who gave birth in hospital and 27 SBAs was carried out. Both medical and non-medical expenses were considered. A linear regression model was used to assess influencing factors on health care expenditure and trends of medical and non-medical expenditure by monthly family income stratified by mode of delivery were assessed. Results Of 581 women, 25% had health care insurance. Health care expenses for delivery care services were significantly higher for caesarean section (270 USD than for vaginal delivery (59 USD. After adjusting for the effect of hospital, family income was significantly associated with all types of expenditure in caesarean section, while it was associated with non-medical and total expenditures in vaginal delivery. Both delivering women and health providers thought that health insurance increased the utilisation of delivery care. Conclusions Substantially higher delivery care expenses were incurred for caesarean section compared to vaginal delivery. Three-fourths of the women who were not insured needed to be responsible for their own health care payment. Women who had higher family

    The Affordable Care Act seeks to overhaul the US health care system by providing insurance for more Americans, improving the quality of health care delivery, and reducing health care expenditures. Although the law's intent is clear, its implementation and effect on patient care remains largely undefined. Herein, we discuss major components of the Affordable Care Act, including the proposed insurance expansion, payment and delivery system reforms (e.g., bundled payments and Accountable Care Organizations), and other reforms relevant to the field of urologic oncology. We also discuss how these proposed reforms may affect patients with urologic cancers.

    Palliative care is a fundamental component of cancer care. As part of the 2011 to 2012 Leadership Development Program (LDP) of the American Society of Clinical Oncology (ASCO), a group of participants was charged with advising ASCO on how to develop a service model integrating palliative care throughout the continuum of cancer care. This article presents the findings of the LDP group. The group focused on the process of palliative care delivery in the oncology setting. We identified key elements for models of palliative care in various settings to be potentially equitable, sustainable, feasible, and acceptable, and here we describe a dynamic model for the integrated, simultaneous implementation of palliative care into oncology practice. We also discuss critical considerations to better integrate palliative care into oncology, including raising consciousness and educating both providers and the public about the importance of palliative care; coordinating palliative care efforts through strengthening affiliations and/or developing new partnerships; prospectively evaluating the impact of palliative care on patient and provider satisfaction, quality improvement, and cost savings; and ensuring sustainability through adequate reimbursement and incentives, including linkage of performance data to quality indicators, and coordination with training efforts and maintenance of certification requirements for providers. In light of these findings, we believe the confluence of increasing importance of incorporation of palliative care education in oncology education, emphasis on value-based care, growing use of technology, and potential cost savings makes developing and incorporating palliative care into current service models a meaningful goal.

    India's health care system, despite several significant achievements, suffers from some weaknesses and deficiencies. There has been a preoccupation with the promotion of curative and clinical services through city based hospitals which have essentially catered to certain sections of the urban population. The concept of health in its totality, with preventive and promotive health care services in addition to the curative, has yet to be made operational. There has been an overdependence on the states for health care measures and voluntary and local effort has not been able to accept responsibility in any significant way. The involvement of the people in solving their health problems has been almost nonexistent. Health needs to be viewed as part of the strategy of human resources development. Horizontal and vertical linkages must be obtained among all the interrelated programs--protected water supply environmental sanitation and hygiene, nutrition, education, family planning, and maternal and child welfare. Only with such linkages can the benefits of the various programs be optimized. An attack on the problems of diseases cannot be completely successful unless it is accompanied by an attack on poverty. For this reason the 6th plan assigns a high priority to programs of promotion, or gainful employment, eradication of poverty, population control, and meeting the basic human needs of the population. The Alma Alta Declaration of 1977 has become the accepted health policy of India, simplified into the slogan "health for all by 2000." To realize this goaL, the Planning Commission recommends in the 6th 5-Year Plan a restructing and reorientation of the country's health services. The proposed alternative scheme is more decentralized and provides for many more people to be trained at the grassroots level. People would be involved in tackling their health problems and community participation would be encouraged. Finally, the alternative strongly urges the screening of patients

    Full Text Available Abstract Cancer vaccines are the promising tools in the hands of the clinical oncologist. Many tumor-associated antigens are excellent targets for immune therapy and vaccine design. Optimally designed cancer vaccines should combine the best tumor antigens with the most effective immunotherapy agents and/or delivery strategies to achieve positive clinical results. Various vaccine delivery systems such as different routes of immunization and physical/chemical delivery methods have been used in cancer therapy with the goal to induce immunity against tumor-associated antigens. Two basic delivery approaches including physical delivery to achieve higher levels of antigen production and formulation with microparticles to target antigen-presenting cells (APCs have demonstrated to be effective in animal models. New developments in vaccine delivery systems will improve the efficiency of clinical trials in the near future. Among them, nanoparticles (NPs such as dendrimers, polymeric NPs, metallic NPs, magnetic NPs and quantum dots have emerged as effective vaccine adjuvants for infectious diseases and cancer therapy. Furthermore, cell-penetrating peptides (CPP have been known as attractive carrier having applications in drug delivery, gene transfer and DNA vaccination. This review will focus on the utilization of different vaccine delivery systems for prevention or treatment of cancer. We will discuss their clinical applications and the future prospects for cancer vaccine development.

    Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of cancer death in the world. Currently available chemotherapy of CRC usually delivers the drug to both normal as well as cancerous tissues, thus leading to numerous undesirable effects. Much emphasis is being laid on the development of effective drug delivery systems for achieving selective delivery of the active moiety at the anticipated site of action with minimized unwanted side effects. Researchers have employed various techniques (dependent on pH, time, pressure and/or bacteria) for targeting drugs directly to the colonic region. On the other hand, systemic drug delivery strategies to specific molecular targets (such as FGFR, EGFR, CD44, EpCAM, CA IX, PPARγ and COX-2) overexpressed by cancerous cells have also been shown to be effective. This review aims to put forth an overview of drug delivery technologies that have been, and may be developed, for the treatment of CRC.

Sleep deprivation can adversely affect clinical performance as severely as alcohol according to some sources. Sleep deficiency may be due to loss of one night’s sleep or repeated interruptions of sleep. Chronic sleep degrades the ability to recognise one’s ability to recognise the impairments induced by sleep loss. The problem of sleep deprivation has vexed acute medical practice for decades. Improvement has been painfully slow. The problem is that all 168 hours throughout every week of every year have to be covered and there are a finite number of doctors to shoulder the burden. There are many strongly held views about how best to provide night-time and week-end care. Constructive innovations are thin on the ground. The biggest gap is between administration and doctors with financial considerations being the limiting factor. It is, however, generally accepted on all sides that sleep loss and fatigue can have adverse effects on both patients and doctors.

    The financial, entrepreneurial, administrative, and legal forces acting within the home care arena make it difficult for clinicians to develop and operate home care initiatives within an academic setting. HomeMed is a clinician-initiated and -directed home care delivery system wholly owned by the University of Michigan. The advantages of a clinician-directed system include: Assurance that clinical and patient-based factors are the primary determinants of strategic and procedural decisions; Responsiveness of the system to clinician needs; Maintenance of an important role for the referring physician in home care; Economical clinical research by facilitation of protocol therapy in ambulatory and home settings; Reduction of lengths of hospital stays through clinician initiatives; Incorporation of outcome analysis and other research programs into the mission of the system; Clinician commitment to success of the system; and Clinician input on revenue use. Potential disadvantages of a clinician-based system include: Entrepreneurial, financial, and legal naivete; Disconnection from institutional administrative and data management resources; and Inadequate clinician interest and commitment. The University of Michigan HomeMed experience demonstrates a model of clinician-initiated and -directed home care delivery that has been innovative, profitable, and clinically excellent, has engendered broad physician, nurse, pharmacist, and social worker enthusiasm, and has supported individual investigator clinical protocols as well as broad outcomes research initiatives. It is concluded that a clinician-initiated and -directed home care program is feasible and effective, and in some settings may be optimal.

  1. Integrating yoga into cancer care.

    2008-02-01

    Although yoga has been practiced in Eastern culture for thousands of years as part of life philosophy, classes in the United States only recently have been offered to people with cancer. The word yoga is derived from the Sanskrit root yuj, meaning to bind, join, and yoke. This reflection of the union of the body, mind, and spirit is what differentiates yoga from general exercise programs. Yoga classes in the United States generally consist of asanas (postures), which are designed to exercise every muscle, nerve, and gland in the body. The postures are combined with pranayama, or rhythmic control of the breath. As a complementary therapy, yoga integrates awareness of breath, relaxation, exercise, and social support--elements that are key to enhancing quality of life in patients with cancer. Yoga practice may assist cancer survivors in managing symptoms such as depression, anxiety, insomnia, pain, and fatigue. As with all exercise programs, participants need to be aware of potential risks and their own limitations. The purpose of this article is to familiarize nurses with yoga as a complementary therapy, including current research findings, types of yoga, potential benefits, safety concerns, teacher training, and ways to integrate yoga into cancer care.

    Analgesics delivered via the oral route of administration (capsules, tablets, or solutions) are most commonly used to treat cancer breakthrough pain (BTP); however, the effectiveness of oral opioids may be limited by slow gastrointestinal absorption and first-pass metabolic effects. Although the limitations presented by oral opioid delivery are acknowledged and formulations and delivery systems that mirror the temporal characteristics of the majority of cancer BTP episodes are available, short-acting oral opioids are the accepted standard of care. The purpose of this review is to provide an overview of the different routes of opioid administration used in the treatment of cancer BTP and briefly discuss the characteristics of different delivery systems.

    2016-03-01

    In response to the growing incidence of cancer in Malawi, a new oncology unit was established at the Queen Elizabeth Central Hospital, Blantyre. The unit opened in 2010, the first in the country, and is led by a single consultant oncologist. In 2012, a healthcare partnership was formed between the oncology and palliative care unit at Queen Elizabeth Central Hospital and the Edinburgh Cancer Centre, UK. The principal objective of the partnership is to help develop high quality multidisciplinary cancer care in Malawi. Methods A needs assessment identified three priority areas for further improvement of cancer services: nurse-led treatment delivery; management of clinical data; and multidisciplinary working. The partnership received grant funding from the Scottish Government Malawi Development Programme in 2013 and a three year project plan was implemented. This has been conducted through a series of reciprocal training visits. Results Key achievements have been completion of a programme of oncology nursing education attended by 32 oncology nurses and other healthcare professionals, which has resulted in increased experience in cancer practice and standardisation of chemotherapy delivery procedures; development of a clinical database that enables prospective collection of data of all new patients with cancer and which links to the Malawi Cancer Registry; development of weekly multidisciplinary meetings involving oncology, gynaecology and surgery that has enabled a cross-specialty approach to patient care. Conclusion The Edinburgh Malawi Cancer Partnership is supporting nursing education, data use and cross-specialty collaboration that we are confident will improve cancer care in Malawi. Future work will focus on the further development of multidisciplinary breast cancer care and the development of a radiotherapy service for patients in Malawi.

    Prior to the advent of the coronary care unit (CCU), patients having an acute myocardial infarction (AMI) were managed on the general medicine wards with reported mortality rates of greater than 30%. The first CCUs are believed to be responsible for reducing mortality attributed to AMI by as much as 40%. This drastic improvement can be attributed to both advances in medical technology and in the process of health care delivery. Evolving considerably since the 1960s, the CCU is now more appropriately labeled as a cardiac intensive care unit (CICU) and represents a comprehensive system designed for the care of patients with an array of advanced cardiovascular disease, an entity that reaches far beyond its early association with AMI. Grouping of patients by diagnosis to a common physical space, dedicated teams of health care providers, as well as the development and implementation of evidence-based treatment algorithms have resulted in the delivery of safer, more efficient care, and most importantly better patient outcomes. The CICU serves as a platform for an integrated, team-based patient care delivery system that addresses a broad spectrum of patient needs. Lessons learned from this model can be broadly applied to address the urgent need to improve outcomes and efficiency in a variety of health care settings.

    With the rapid growth of online social networking for health, health care systems are experiencing an inescapable increase in complexity. This is not necessarily a drawback; self-organising, adaptive networks could become central to future health care delivery. This paper considers whether social networks composed of patients and their social circles can compete with, or complement, professional networks in assembling health-related information of value for improving health and health care. Using the framework of analysis of a two-sided network--patients and providers--with multiple platforms for interaction, we argue that the structure and dynamics of such a network has implications for future health care. Patients are using social networking to access and contribute health information. Among those living with chronic illness and disability and engaging with social networks, there is considerable expertise in assessing, combining and exploiting information. Social networking is providing a new landscape for patients to assemble health information, relatively free from the constraints of traditional health care. However, health information from social networks currently complements traditional sources rather than substituting for them. Networking among health care provider organisations is enabling greater exploitation of health information for health care planning. The platforms of interaction are also changing. Patient-doctor encounters are now more permeable to influence from social networks and professional networks. Diffuse and temporary platforms of interaction enable discourse between patients and professionals, and include platforms controlled by patients. We argue that social networking has the potential to change patterns of health inequalities and access to health care, alter the stability of health care provision and lead to a reformulation of the role of health professionals. Further research is needed to understand how network structure combined with

    Although the effectiveness of prostate cancer screening is controversial, screening rates have risen dramatically among primary care providers in the United States. The authors' findings suggest more collaboration among primary care and specialty organizations, especially with respect to decision aid endorsement, is needed to achieve more discriminatory and patient-centered prostate cancer screening.

    2016-05-01

    Full Text Available Demand for cancer genetic counseling has grown rapidly in recent years as germline genomic information has become increasingly incorporated into cancer care and the field has entered the public consciousness through high-profile celebrity publications. Increased demand and existing variability in the availability of trained cancer genetics clinicians place a priority on developing and evaluating alternate service delivery models for genetic counseling. This mini-review summarizes the state of science regarding service delivery models such as telephone counseling, telegenetics and group counseling. Research on comparative effectiveness of these models in traditional individual, in-person genetic counseling has been promising for improving access to care in a manner acceptable to patients. Yet, it has not fully evaluated the short- and long-term patient- and system-level outcomes that will help answer the question of whether these models achieve the same beneficial psychosocial and behavioral outcomes as traditional cancer genetic counseling. We propose a research agenda focused on comparative effectiveness of available service delivery models and how to match models to patients and practice settings. Only through this rigorous research can clinicians and systems find the optimal balance of clinical quality, ready and secure access to care, and financial sustainability. Such research will be integral to achieving the promise of genomic medicine in oncology.

    Full Text Available Background: A supportive needs assessment is an essential component of any care program. There is no research evidence regarding the supportive care needs of cancer patients in Iran or other Middle Eastern countries. Aims: The aim of this study was to determine the supportive care needs of Iranian cancer patients. Materials and Methods: This descriptive study was conducted in a referral medical center in the northwest of Iran. A total of 274 cancer patients completed the Supportive Care Needs Survey (SCNS-59. Descriptive statistics were used for data analysis. Results: In 18 items of the SCNS, more than 50% of the participants reported that their needs were unmet. Most frequently, unmet needs were related to the health system, information, physical, and daily living domains, and most met needs were related to sexuality, patient care, and support domains. Conclusions: Iranian cancer patients experience many unmet needs and there is an urgent need for establishing additional supportive care services in Iran.

    2017-01-01

    Summary Sir William Osler has been quoted as saying “If it were not for the great variability among individuals, medicine might as well be a science and not an art”. Molecular profiles, be they host or those providing insight into the genomic changes that define a cancerous cell, together possess the predictive ability required for the various aspects of individualized care: risk assessment, patient prognosis, and prediction of therapeutic responses. Such profiles, obtained by RNA, DNA and protein microarrays, SNP arrays, methylation screens, and high throughput or targeted gene sequencing can provide patient- and tumor-specific information that details the biological complexity of a particular cancer and can be exploited to understand its clinical implications and glean therapeutic insights. This knowledge is also being combined with host factors to begin formulating an understanding at the system level of how the tumor interacts with the host and how this relationship can be exploited therapeutically or for biomarker development. Here we discuss these advances and how they may relate to urologic oncology. PMID:22489325

    2014-02-01

    Individuals with schizophrenia are a vulnerable population that has been relatively neglected in health disparities research. Despite having an equivalent risk of developing most cancers, patients with schizophrenia are more likely to die of cancer than the general population. Cancer care disparities are likely the result of patient-, provider-, and systems-level factors and influenced by the pervasive stigma of mental illness. Individuals with schizophrenia have higher rates of health behaviors linked with cancer mortality including cigarette smoking. They also have significant medical comorbidity, are less likely to have up-to-date cancer screening, and may present at more advanced stages of illness. Patients with schizophrenia may be less likely to receive chemotherapy or radiotherapy, have more postoperative complications, and have less access to palliative care. However, opportunities exist for the interdisciplinary team, including medical, surgical, and radiation oncologists; psychiatrists; and primary care physicians, to intervene throughout the continuum of cancer care to promote survival and quality of life. This review summarizes data on overall and cancer-specific mortality for individuals with schizophrenia and reviews specific disparities across the cancer care continuum of screening, diagnosis, treatment, and end-of-life care. Using a case, the authors illustrate clinical challenges for this population including communication, informed consent, and risk of suicide, and provide suggestions for care. Finally, recommendations for research to address the disparities in cancer care for individuals with schizophrenia are discussed. Despite significant challenges, with collaboration between oncology and mental health teams, individuals with schizophrenia can receive high-quality cancer care.

  16. Adapting chronic care models for diabetes care delivery inlow-and-middle-income countries: A review

    2015-01-01

    A contextual review of models for chronic care was doneto develop a context-adapted chronic care model-basedservice delivery model for chronic conditions includingdiabetes. The Philippines was used as the setting ofa low-to-middle-income country. A context-basednarrative review of existing models for chronic carewas conducted. A situational analysis was done at thegrassroots level, involving the leaders and members ofthe community, the patients, the local health system andthe healthcare providers. A second analysis making useof certain organizational theories was done to explore onimproving feasibility and acceptability of organizing carefor chronic conditions. The analyses indicated that carefor chronic conditions may be introduced, consideringthe needs of people with diabetes in particular andthe community in general as recipients of care, andthe issues and factors that may affect the healthcareworkers and the health system as providers of thiscare. The context-adapted chronic care model-basedservice delivery model was constructed accordingly.Key features are incorporation of chronic care in thehealth system's services; assimilation of chronic caredelivery with the other responsibilities of the healthcareworkers but with redistribution of certain tasks; andensuring that the recipients of care experience thewhole spectrum of basic chronic care that includes educationand promotion in the general population, riskidentification, screening, counseling including self-caredevelopment, and clinical management of the chroniccondition and any co-morbidities, regardless of level ofcontrol of the condition. This way, low-to-middle incomecountries can introduce and improve care for chronicconditions without entailing much additional demand ontheir limited resources.

    Mexican American women experience unique health care needs related to integration of Mexican and American cultures. To learn how to better promote self-care practices and service utilization in women of Mexican origin living in Texas, researchers used a qualitative approach to interview a convenience sample of 11 low-income women attending a health clinic. Researchers collected narrative data about the women's perceptions of health, wellness, and self-care. Using the matrix approach described by Miles and Huberman, we organized findings around women's roles, including participants' descriptions of themselves, their health and wellness awareness, self-care practices for health/illness and wellness/nonwellness, barriers to self-care, origin of self-care practices, and perceptions of life control. Implications for health planning and service delivery are presented.

    Radiologists aspire to improve patient experience and engagement, as part of the Triple Aim of health reform. Patient engagement requires active partnerships among health providers and patients, and rigorous teamwork provides a mechanism for this. Patient and care team engagement are crucial at the time of cancer diagnosis and care initiation but are complicated by the necessity to orchestrate many interdependent consultations and care events in a short time. Radiology often serves as the patient entry point into the cancer care system, especially for breast cancer. It is uniquely positioned to play the value-adding role of facilitating patient and team engagement during cancer care initiation. The 4R approach (Right Information and Right Care to the Right Patient at the Right Time), previously proposed for optimizing teamwork and care delivery during cancer treatment, could be applied at the time of diagnosis. The 4R approach considers care for every patient with cancer as a project, using project management to plan and manage care interdependencies, assign clear responsibilities, and designate a quarterback function. The authors propose that radiology assume the quarterback function during breast cancer care initiation, developing the care initiation sequence, as a project care plan for newly diagnosed patients, and engaging patients and their care teams in timely, coordinated activities. After initial consultations and treatment plan development, the quarterback function is transitioned to surgery or medical oncology. This model provides radiologists with opportunities to offer value-added services and solidifies radiology's relevance in the evolving health care environment. To implement 4R at cancer care initiation, it will be necessary to change the radiology practice model to incorporate patient interaction and teamwork, develop 4R content and local adaption approaches, and enrich radiology training with relevant clinical knowledge, patient interaction

    Empirical evidence on sustainability of programs that improve the quality of care delivery over time is lacking. Therefore, this study aims to identify the predictive role of short and long term improvements in quality of chronic care delivery on program sustainability. In this longitudinal study, professionals [2010 (T0): n=218, 55% response rate; 2011 (T1): n=300, 68% response rate; 2012 (T2): n=265, 63% response rate] from 22 Dutch disease-management programs completed surveys assessing quality of care and program sustainability. Our study findings indicated that quality of chronic care delivery improved significantly in the first 2 years after implementation of the disease-management programs. At T1, overall quality, self-management support, delivery system design, and integration of chronic care components, as well as health care delivery and clinical information systems and decision support, had improved. At T2, overall quality again improved significantly, as did community linkages, delivery system design, clinical information systems, decision support and integration of chronic care components, and self-management support. Multilevel regression analysis revealed that quality of chronic care delivery at T0 (pquality changes in the first (pmanagement programs based on the chronic care model improved the quality of chronic care delivery over time and that short and long term changes in the quality of chronic care delivery predicted the sustainability of the projects.

    2012-06-01

    Most patients with Graves' orbitopathy have mild disease that requires no or minimal intervention. For the minority of patients with moderate or severe disease, multiple medical and surgical treatments may be required at different stages. It is crucial that such patients are monitored closely and treatments applied with care in the right sequence. Medical treatments should be used as early as possible and only during the active phase of the disease. Rehabilitative surgery is indicated in the inactive phase of the disease and should follow the sequence: surgical decompression followed by eye muscle surgery, followed by lid surgery. Delivery of care in a coordinated fashion that makes use of best available expertise is important and best implemented through a Combined Thyroid Eye clinic.

    Cancer care delivery is highly complex. Treatment involves coordination within oncology health-care teams and across other teams of referring primary and specialty providers (a team of teams). Each team interfaces with patients and caregivers to offer component parts of comprehensive care. Because patients frequently obtain specialty care from divergent health-care systems resulting in cross-system health-care use, oncology teams need mechanisms to coordinate and collaborate within and across health-care systems to optimize clinical outcomes for all cancer patients. Transactive memory is one potential strategy that can help improve comprehensive patient care delivery. Transactive memory is a process by which two or more team professionals develop a shared system for encoding, storing, and retrieving information. Each professional is responsible for retaining only part of the total information. Applying this concept to a team of teams results in system benefits wherein all teams share an understanding of specialized knowledge held by each component team. The patient's role as the unifying member of the team of teams is central to successful treatment delivery. This clinical case presents a patient who is receiving oral treatment for advanced prostate cancer within two health systems. The case emphasizes the potential for error when multiple teams function without a point team (the team coordinating efforts of all other primary and specialty teams) and when the specialty knowledge of providers and patients is not well integrated into all phases of the care delivery process.

    2014-02-05

    Tumor antigenic peptides therapeutics is a promising field for cancer immunotherapy. Benefits include the ease and rapid synthesis of antigenic peptides and capacity for modifications. In the past years, many peptide-based cancer vaccines have been tested in clinical trials with a limited success because of the difficulties associated with peptide stability and delivery approaches, consequently, resulting in inefficient antigen presentation and low response rates in patients with cancer. The development of suitable and efficient vaccine carrier systems still remains a major challenge. This article aims to describe a new delivery approach for tumor antigenic peptides and rationales of dendritic cells (DCs)-based vaccination. In order to elicit enhanced immune responses, poly(DL-lactide-co-glycolide) (PLGA), which has been approved by the US Food and Drug Administration (FDA) for the use of drug delivery, diagnostics and other applications of clinical and basic science research were employed for the formulation of making nanoparticles (NPs) while delivering tumor antigenic peptides.

    A project of the American Lymphedema Framework Project (ALFP), this review seeks to examine the policy and economic impact of caring for patients with lymphedema, a common side effect of cancer treatment. This review is the first of its kind undertaken to investigate, coordinate, and streamline lymphedema policy initiatives in the United States with potential applicability worldwide. As part of a large scale literature review aiming to systematically evaluate the level of evidence of contemporary peer-reviewed lymphedema literature (2004 to 2011), publications on care delivery models, health policy, and economic impact were retrieved, summarized, and evaluated by a team of investigators and clinical experts. The review substantiates lymphedema education models and clinical models implemented at the community, health care provider, and individual level that improve delivery of care. The review exposes the lack of economic analysis related to lymphedema. Despite a dearth of evidence, efforts towards policy initiatives at the federal and state level are underway. These initiatives and the evidence to support them are examined and recommendations for translating these findings into clinical practice are made. Medical and community-based disease management interventions, taking on a public approach, are effective delivery models for lymphedema care and demonstrate great potential to improve cancer survivorship care. Efforts to create policy at the federal, state, and local level should target implementation of these models. More research is needed to identify costs associated with the treatment of lymphedema and to model the cost outlays and potential cost savings associated with comprehensive management of chronic lymphedema.

    Full Text Available The field of nanomedicine has emerged as an approach to enhance the specificity and efficacy of cancer treatments as stand-alone therapies and in combination with standard chemotherapeutic treatment regimens. The current standard of care for metastatic cancer, doxorubicin (DOX, is presented with challenges, namely toxicity due to a lack of specificity and targeted delivery. Nano-enabled targeted drug delivery systems can provide an avenue to overcome these issues. Nanodiamonds (ND, in particular, have been researched over the past five years for use in various drug delivery systems but minimal work has been done that incorporates targeting capability. In this study, a novel targeted drug delivery system for bone metastatic prostate cancer was developed, characterized, and evaluated in vitro. NDs were conjugated with the Asp–Gly–Glu–Ala (DGEA peptide to target α2β1 integrins over-expressed in prostate cancers during metastasis. To facilitate drug delivery, DOX was adsorbed to the surface of the ND-DGEA conjugates. Successful preparation of the ND-DGEA conjugates and the ND-DGEA+DOX system was confirmed with transmission electron microscopy, hydrodynamic size, and zeta potential measurements. Since traditional DOX treatment regimens lack specificity and increased toxicity to normal tissues, the ND-DGEA conjugates were designed to distinguish between cells that overexpress α2β1 integrin, bone metastatic prostate cancers cells (PC3, and cells that do not, human mesenchymal stem cells (hMSC. Utilizing the ND-DGEA+DOX system, the efficacy of 1 µg/mL and 2 µg/mL DOX doses increased from 2.5% to 12% cell death and 11% to 34% cell death, respectively. These studies confirmed that the delivery and efficacy of DOX were enhanced by ND-DGEA conjugates. Thus, the targeted ND-DGEA+DOX system provides a novel approach for decreasing toxicity and drug doses.

    Full Text Available Colorectal cancer (CRC is the third most common cancer and the fourth leading cause of cancer death in the world. Currently available chemotherapy of CRC usually delivers the drug to both normal as well as cancerous tissues, thus leading to numerous undesirable effects. Much emphasis is being laid on the development of effective drug delivery systems for achieving selective delivery of the active moiety at the anticipated site of action with minimized unwanted side effects. Researchers have employed various techniques (dependent on pH, time, pressure and/or bacteria for targeting drugs directly to the colonic region. On the other hand, systemic drug delivery strategies to specific molecular targets (such as FGFR, EGFR, CD44, EpCAM, CA IX, PPARγ and COX-2 overexpressed by cancerous cells have also been shown to be effective. This review aims to put forth an overview of drug delivery technologies that have been, and may be developed, for the treatment of CRC.

    The growing complexity of technology, equipment, and devices involved in patient care delivery can be staggering and overwhelming. Technology is intended to be a tool to help clinicians, but it can also be a frustrating hindrance if not thoughtfully planned and strategically aligned. Critical care nurses are key partners in the collaborations needed to improve safety and quality through health information technology (IT). Nurses must advocate for systems that are interoperable and adapted to the context of care experiences. The involvement and collaboration between clinicians, information technology specialists, biomedical engineers, and vendors has never been more relevant and applicable. Working together strategically with a shared vision can effectively provide a seamless clinical workflow, maximize technology investments, and ultimately improve patient care delivery and outcomes. Developing a strategic integrated clinical and IT roadmap is a critical component of today's health care environment. How can technology strategy be aligned from the executive suite to the bedside caregiver? What is the model for using clinical workflows to drive technology adoption? How can the voice of the critical care nurse strengthen this process? How can success be assured from the initial assessment and selection of technology to a sustainable support model? What is the vendor's role as a strategic partner and "co-caregiver"?

  10. Health care delivery and the training of surgeons.

    Most countries have mastered the art of cost containment by global budgeting for public expenditure. It is not as yet clear whether the other option, managed care, or managed competition will accomplish cost control in America. Robert Evans, a Canadian health care expert, remains skeptical. He says, "HMO's are the future, always have been and always will be." With few exceptions, the amount spent on health care is not a function of the system but of the gross domestic product per person. Great Britain is below the line expected for expenditure, which may be due to truly impressive waiting lists. The United States is above the line, which is probably related to the overhead costs to administer the system and the strong demand by patients for prompt and highly sophisticated diagnostic measures and treatments. Canada is on the line, but no other country has subscribed to the Canadian veto on private insurance. Reform or changes are occurring in all countries and will continue to do so. For example, we are as terrified of managed care in Canada as you are of our brand of socialized insurance. We distrust practice by protocol just as you abhor waiting lists. From my perspective as a surgeon, I envision an ideal system that would cover all citizens, would maintain choice of surgeon by patients, would provide mechanisms for cost containment that would have the active and continuous participation of the medical profession, and would provide for research and development. Any alteration in health care delivery in the United States that compromises biomedical research and development will be a retrogressive, expensive step that could adversely affect the health of nations everywhere. Finally, a continuing priority of our training programs must be to ensure that the surgeon participating in this system continues to treat each patient as an individual with concern for his or her own needs.

    Our objective was to determine the availability and quality of obstetric care to improve resource allocation in northern Tanzania. We surveyed all facilities providing delivery services (n=129) in six districts in northern Tanzania using the UN Guidelines for monitoring emergency obstetric care (EmOC). The three last questions in this audit outline are examined: Are the right women (those with obstetric complications) using emergency obstetric care facilities (Met Need)? Are sufficient quantities of critical services being provided (cesarean section rate (CSR))? Is the quality of the services adequate (case fatality rate (CFR))? Complications are calculated using Plan 3 of the UN Guidelines to assess the value of routine data for EmOC indicator monitoring. Nearly 60% of the expected complicated deliveries in the study population were conducted at EmOC qualified health facilities. 81.2% of the expected complicated deliveries are conducted in any facility (including facilities not qualifying as EmOC facilities). There is an inadequate level of critical services provided (CSR 4.6). Voluntary agencies provide most of these services in rural settings. All indicators show large variations with the setting (urban/rural location, level and ownership of facilities). Finally, there is large variation in the CFR with only one facility meeting the minimum accepted level. Utilization and quality of critical obstetric services at lower levels and in rural districts must be improved. The potential for improving the resource allocation within lower levels of the health care system is discussed. Given the small number of qualified facilities yet relatively high Met Need, we argue that it is neither the mothers' ignorance nor their lack of ability to get to a facility that is the main barrier to receiving quality care when needed, but rather the lack of quality care at the facility. Little can be concluded using the CFR to describe the quality of services provided.

    Polymeric nanoparticles and liposomes have been the platform of choice for nanoparticle-based cancer drug delivery applications over the past decade, but extensive research has revealed their limitations as drug delivery carriers. A hybrid class of nanoparticles, aimed at combining the advantages of both polymeric nanoparticles and liposomes, has received attention in recent years. These core/shell type nanoparticles, frequently referred to as lipid-polymer hybrid nanoparticles (LPNs), possess several characteristics that make them highly suitable for drug delivery. This review introduces the formulation methods used to synthesize LPNs and discusses the strategies used to treat cancer, such as by targeting the tumor microenvironment or vasculature. Finally, it discusses the challenges that must be overcome to realize the full potential of LPNs in the clinic.

    Full Text Available Background: In Tanzania, a country of 42 million, access to oral morphine is rare.Aim: To demonstrate the effectiveness of palliative care teams in reducing patients’ pain and in increasing other positive life qualities in the absence of morphine; and to document the psychological burden experienced by their clinical providers, trained in morphine delivery, as they observed their patients suffering and in extreme pain.Setting: One hundred and forty-fie cancer patients were included from 13 rural hospitals spread across Tanzania.Method: A mixed method study beginning with a retrospective quantitative analysis of cancer patients who were administered the APCA African POS tool four times. Bivariate analyses of the scores at time one and four were compared across the domains. The qualitative arm included an analysis of interviews with six nurses, each with more than fie years’ palliative care experience and no access to strong opioids.Results: Patients and their family caregivers identifid statistically signifiant (p < 0.001 improvements in all of the domains. Thematic analysis of nurse interviews described the patient and family benefis from palliative care but also their great distress when ‘bad cases’ arose who would likely benefi only from oral morphine.Conclusion: People living with chronic cancer-related pain who receive palliative care experience profound physical, spiritual and emotional benefis even without oral morphine. These results demonstrate the need for continued advocacy to increase the availability of oral morphine in these settings in addition to palliative care services.

    Full Text Available Abstract Background National cancer policies identify the improvement of care coordination as a priority to improve the delivery of health services for people with cancer. Identification of the current barriers to effective cancer care coordination is needed to drive service improvement. Methods A qualitative study was undertaken in which semi-structured individual interviews and focus groups were conducted with those best placed to identify issues; patients who had been treated for a range of cancers and their carers as well as health professionals involved in providing cancer care. Data collection continued until saturation of concepts was reached. A grounded theory influenced approach was used to explore the participants' experiences and views of cancer care coordination. Results Overall, 20 patients, four carers and 29 health professionals participated. Barriers to cancer care coordination related to six aspects of care namely, recognising health professional roles and responsibilities, implementing comprehensive multidisciplinary team meetings, transitioning of care: falling through the cracks, inadequate communication between specialist and primary care, inequitable access to health services and managing scarce resources. Conclusions This study has identified a number of barriers to coordination of cancer care. Development and evaluation of interventions based on these findings is now required.

    2011-06-08

    The purpose of this paper is to show some aspects of music therapy application in cancer care and to present the integration of music therapy program into a continuous supportive cancer care for inpatients. A cancer diagnosis is one of the most feared and serious life events that causes stress in individuals and families. Cancer disrupts social, physical and emotional well-being and results in a range of emotions, including anger, fear, sadness, guilt, embarrassment and shame. Music therapy is a part of a complementary medicine program in supportive cancer care which accompanies medical treatment. There are many benefits of music therapy for cancer patients-interactive music therapy techniques (instrumental improvisation, singing) as well as receptive music therapy techniques (listening to recorded or live music, music and imaginary) can be used to improve mood, decrease stress, pain, anxiety level and enhance relaxation. Music therapy is an effective form of supporting cancer care for patients during the treatment process. It may be also basic for planning effective programs of rehabilitation to promote wellness, improve physical and emotional well-being and the quality of life.

    A new paradigm for an effective delivery of therapeutics into cancer cells is presented. Degradable porous silicon carriers, which are tailored to carry and release a model anti-cancer drug, are biolistically bombarded into in-vitro cancerous targets. We demonstrate the ability to launch these highly porous microparticles by a pneumatic capillary gene gun, which is conventionally used to deliver cargos by heavy metal carriers. By optimizing the gun parameters e.g., the accelerating gas pressure, we have successfully delivered the porous carriers, to reach deep targets and to cross a skin barrier in a highly spatial resolution. Our study reveals significant cytotoxicity towards the target human breast carcinoma cells following the delivery of drug-loaded carriers, while administrating empty particles results in no effect on cell viability. The unique combination of biolistics with the temporal control of payload release from porous carriers presents a powerful and non-conventional platform for designing new therapeutic strategies.

    Being adequately prepared for an experience such as cancer empowers patients, lowers distress, improves coping, supports self-management, promotes recovery, and improves quality of life. However, patients with cancer report unmet informational and support needs across the cancer trajectory. The purpose of this article is to describe the relationship of information preparation and patient outcomes, identify information and support needs across the cancer trajectory, and describe the role of oncology nurses in the delivery of high-quality patient-centered cancer care. The middle range theory of "Carrying On" was used to identify information and support needs during different phases of the cancer trajectory from treatment to survivorship. The authors concluded that nurses should engage the patient in a relational exchange of information; provide concrete, understandable information across specific times in the cancer experience; and use creative approaches to minimize barriers in meeting patient needs to achieve high-quality patient-centered cancer care.

However, most anticancer agents cannot differentiate between cancerous and normal cells, resulting in severe systemic toxicity. In addition, acquired drug resistance during the chemotherapy treatment further decreases treatment efficacy. With the proper treatment strategy, nanodrug carriers, such as liposomes/immunoliposomes, may be able to reduce undesired side effects of chemotherapy, to overcome the acquired multidrug resistance, and to further improve the treatment efficacy. In this study, a novel combinational targeted drug delivery system was developed by encapsulating antiangiogenesis drug bevacizumab into liposomes and encapsulating chemotherapy drug doxorubicin (DOX into immunoliposomes where the human epidermal growth factor receptor 2 (HER2 antibody was used as a targeting ligand. This novel combinational system was tested in vitro using a HER2 positive and multidrug resistant breast cancer cell line (BT-474/MDR, and in vivo using a xenograft mouse tumor model. In vitro cell culture experiments show that immunoliposome delivery led to a high cell nucleus accumulation of DOX, whereas free DOX was observed mostly near the cell membrane and in cytoplasm due to the action of P-gp. Combining liposomal bevacizumab with immunoliposomal DOX achieved the best tumor growth inhibition and the lowest toxicity. Tumor size decreased steadily within a 60-day observation period indicating a potential synergistic effect between DOX and bevacizumab through the targeted delivery. Our findings clearly indicate that tumor growth was significantly

    Nanotechnology-based chemotherapeutics and imaging agents represent a new era of "cancer nanomedicine" working to deliver versatile payloads with favorable pharmacokinetics and capitalize on molecular and cellular targeting for enhanced specificity, efficacy, and safety. Despite the versatility of many nanomedicine-based platforms, translating new drug or imaging agents to the clinic is costly and often hampered by regulatory hurdles. Therefore, translating cancer nanomedicine may largely be application-defined, where materials are adapted only toward specific indications where their properties confer unique advantages. This strategy may also realize therapies that can optimize clinical impact through combinatorial nanomedicine. In this review, we discuss how particular materials lend themselves to specific applications, the progress to date in clinical translation of nanomedicine, and promising approaches that may catalyze clinical acceptance of nano.

    Esophageal cancer patients are often diagnosed as "advanced" cases. These patients are subjected to palliative stenting using self-expanding metallic stents (SEMS) to maintain oral alimentation. Unfortunately, SEMS get reoccluded due to tumor growth, in and over the stent struts. To investigate potential solutions to this problem, docetaxel (DTX) delivery films were prepared using PurSil AL 20 (PUS), which can be used as a covering material for the SEMS. Drug-polymer miscibility and interactions were studied. Bilayer films were prepared by adhering the blank film to the DTX loaded film in order to maintain the unidirectional delivery to the esophagus. In vitro release and the local DTX delivery were studied using in vitro permeation experiments. It was found that DTX and PUS were physically and chemically compatible. The bilayer films exhibited sustained release (>30 days) and minimal DTX permeation through esophageal tissues in vitro. The rate-determining step for the DTX delivery was calculated. It was found that >0.9 fraction of rate control lies with the esophageal tissues, suggesting that DTX delivery can be sustained for longer periods compared to the in vitro release observed. Thus, the bilayer films can be developed as a localized sustained delivery system in combination with the stent.

    Facility delivery is an important aspect of the strategy to reduce maternal and newborn mortality. Geographic access to care is a strong determinant of facility delivery, but few studies have simultaneously considered the influence of facility quality, with inconsistent findings. In rural Brong Ahafo region in Ghana, we combined surveillance data on 11,274 deliveries with quality of care data from all 64 delivery facilities in the study area. We used multivariable multilevel logistic regression to assess the influence of distance and several quality dimensions on place of delivery. Women lived a median of 3.3 km from the closest delivery facility, and 58% delivered in a facility. The probability of facility delivery ranged from 68% among women living 1 km from their closest facility to 22% among those living 25 km away, adjusted for confounders. Measured quality of care at the closest facility was not associated with use, except that facility delivery was lower when the closest facility provided substandard care on the EmOC dimension. These results do not imply, however, that we should increase geographic accessibility of care without improving facility quality. While this may be successful in increasing facility deliveries, such care cannot be expected to reduce maternal and neonatal mortality. PMID:27506292

    With over 1 million people living with HIV, the US faces national challenges in HIV care delivery due to an inadequate HIV specialist workforce and the increasing role of non-communicable chronic diseases in driving morbidity and mortality in HIV-infected patients. Alternative HIV care delivery models, which include substantial roles for advanced practitioners and/or coordination between specialty and primary care settings in managing HIV-infected patients, may address these needs. We aimed to systematically review the evidence on patient-level HIV-specific and primary care health outcomes for HIV-infected adults receiving outpatient care across HIV care delivery models. We identified randomized trials and observational studies from bibliographic and other databases through March 2016. Eligible studies met pre-specified eligibility criteria including on care delivery models and patient-level health outcomes. We considered all available evidence, including non-experimental studies, and evaluated studies for risk of bias. We identified 3605 studies, of which 13 met eligibility criteria. Of the 13 eligible studies, the majority evaluated specialty-based care (9 studies). Across all studies and care delivery models, eligible studies primarily reported mortality and antiretroviral use, with specialty-based care associated with mortality reductions at the clinician and practice levels and with increased antiretroviral initiation or use at the clinician level but not the practice level. Limited and heterogeneous outcomes were reported for other patient-level HIV-specific outcomes (e.g., viral suppression) as well as for primary care health outcomes across all care delivery models. No studies addressed chronic care outcomes related to aging. Limited evidence was available across geographic settings and key populations. As re-design of care delivery in the US continues to evolve, better understanding of patient-level HIV-related and primary care health outcomes, especially

    Survivors of childhood cancer are at risk of long-term adverse effects and late effects of the disease and/or its treatment. In response to national recommendations to improve evidence-based follow-up care, a web-based support system for clinical decision making, the Passport for Care (PFC), was developed for use at the point of care to produce screening recommendations individualized to the survivor. To date, the PFC has been implemented in over half of the nearly 200 clinics affiliated with the Children's Oncology Group across the USA. Most clinician users report that the PFC has been integrated into clinic workflows, and that it fosters improved conversations with survivors about the potential late effects a survivor might experience and about the screening and/or behavioural interventions recommended to improve health status. Furthermore, clinicians using the PFC have indicated that they adhered more closely to follow-up care guidelines. Perspectives on the challenges encountered and lessons learned during the development and deployment of the PFC are reviewed and contrasted with other nationwide approaches to the provision of guidance on survivor follow-up care; furthermore, the implications for the care of childhood cancer survivors are discussed.

    The International Psycho-oncology Society (IPOS) has just celebrated its 30th anniversary. The growth of psychosocial oncology has been exponential, and this relatively new field is becoming a core service that focuses on prevention, reducing the burden of cancer, and enhancing the quality of life from time of diagnosis, through treatment, survivorship, and palliative care. Looking back over the past 30 years, we see that cancer care globally has evolved to a new and higher standard. Today, 'cancer care for the whole patient' is being accomplished with an evidence-based model that addresses psychosocial needs and integrates psycho-oncology into the treatment and care of patients. The President's Plenary Session in Lisbon, Portugal, highlighted the IPOS Mission of promoting global excellence in psychosocial care of people affected by cancer through our research, public policy, advocacy, and education. The internationally endorsed IPOS Standard of Quality Cancer Care, for example, clearly states the necessity of integrating the psychosocial domain into routine care, and that distress should be measured as the sixth vital sign after temperature, blood pressure, pulse, respiratory rate, and pain. The plenary paper also discussed the global progress being made in Europe, North America, and Australia in providing quality cancer care for the whole patient. Collaborative partnerships between IPOS and organizations such as the European Partnership Action Against Cancer and the World Health Organization are essential in building capacity for the delivery of high-quality psycho-oncology services in the future.

    The aim of this review is to summarize advances that have been made in the delivery of phytochemicals for cancer therapy by the use of nanotechnology. Over recent decades, much research effort has been invested in developing phytochemicals as cancer therapeutic agents. However, several impediments to their wide spread use as drugs still have to be overcome. Among these are low solubility, poor penetration into cells, high hepatic disposition, and narrow therapeutic index. Rapid clearance or uptake by normal tissues and wide tissue distribution result in low drug accumulation in the target tumor sites can result in undesired drug exposure in normal tissues. Association with or encapsulation in nanoscale drug carriers is a potential strategy to address these problems. This review discussed lessons learned on the use of nanotechnology for delivery of phytochemicals that been tested in clinical trials or are moving towards the clinic.

    The continuous identification of molecular changes deregulating critical pathways in pancreatic tumor cells provides us with a large number of novel candidates to engineer gene-targeted approaches for pancreatic cancer treatment. Targets—both protein coding and non-coding—are being exploited in gene therapy to influence the deregulated pathways to facilitate cytotoxicity, enhance the immune response or sensitize to current treatments. Delivery vehicles based on viral or non-viral systems as well as cellular vectors with tumor homing characteristics are a critical part of the design of gene therapy strategies. The different behavior of tumoral versus non-tumoral cells inspires vector engineering with the generation of tumor selective products that can prevent potential toxic-associated effects. In the current review, a detailed analysis of the different targets, the delivery vectors, the preclinical approaches and a descriptive update on the conducted clinical trials are presented. Moreover, future possibilities in pancreatic cancer treatment by gene therapy strategies are discussed.

    Full Text Available Disseminated metastatic breast cancer needs aggressive treatment due to its reduced response to anticancer treatment and hence low survival and quality of life. Although in theory a combination drug therapy has advantages over single-agent therapy, no appreciable survival enhancement is generally reported whereas increased toxicity is frequently seen in combination treatment especially in chemotherapy. Currently used combination treatments in metastatic breast cancer will be discussed with their challenges leading to the introduction of novel combination anticancer drug delivery systems that aim to overcome these challenges. Widely studied drug delivery systems such as liposomes, dendrimers, polymeric nanoparticles, and water-soluble polymers can concurrently carry multiple anticancer drugs in one platform. These carriers can provide improved target specificity achieved by passive and/or active targeting mechanisms.

    Nanoparticles have increasingly been used for a variety of applications, most notably for the delivery of therapeutic and diagnostic agents. A large number of nanoparticle drug delivery systems have been developed for cancer treatment and various materials have been explored as drug delivery agents to improve the therapeutic efficacy and safety of anticancer drugs. Natural biomolecules such as proteins are an attractive alternative to synthetic polymers which are commonly used in drug formulations because of their safety. In general, protein nanoparticles offer a number of advantages including biocompatibility and biodegradability. They can be prepared under mild conditions without the use of toxic chemicals or organic solvents. Moreover, due to their defined primary structure, protein-based nanoparticles offer various possibilities for surface modifications including covalent attachment of drugs and targeting ligands. In this paper, we review the most significant advancements in protein nanoparticle technology and their use in drug delivery arena. We then examine the various sources of protein materials that have been used successfully for the construction of protein nanoparticles as well as their methods of preparation. Finally, we discuss the applications of protein nanoparticles in cancer therapy.

    2013-05-01

    The specialty pharmaceuticals market is expanding more rapidly than the traditional pharmaceuticals market. Specialty pharmacy operations have evolved to deliver selected medications and associated clinical services. The growing role of specialty drugs requires new approaches to managing the use of these drugs. The focus, expectations, and emphasis in specialty drug management in an integrated health care delivery system such as Kaiser Permanente (KP) can vary as compared with more conventional health care systems. The KP Specialty Pharmacy (KP-SP) serves KP members across the United States. This descriptive account addresses the impetus for specialty drug management within KP, the use of tools such as an electronic health record (EHR) system and process management software, the KP-SP approach for specialty pharmacy services, and the emphasis on quality measurement of services provided. Kaiser Permanente's integrated system enables KP-SP pharmacists to coordinate the provision of specialty drugs while monitoring laboratory values, physician visits, and most other relevant elements of the patient's therapy. Process management software facilitates the counseling of patients, promotion of adherence, and interventions to resolve clinical, logistic, or pharmacy benefit issues. The integrated EHR affords KP-SP pharmacists advantages for care management that should become available to more health care systems with broadened adoption of EHRs. The KP-SP experience may help to establish models for clinical pharmacy services as health care systems and information systems become more integrated.

    Providing quality care for all children living with HIV/AIDS remains a global challenge and requires the development of new healthcare delivery strategies. The care delivery value chain (CDVC) is a framework that maps activities required to provide effective and responsive care for a patient with a particular disease across the continuum of care. By mapping activities along a value chain, the CDVC enables managers to better allocate resources, improve communication, and coordinate activities. We report on the successful application of the CDVC as a strategy to optimize care delivery and inform quality improvement (QI) efforts with the overall aim of improving care for Pediatric HIV patients in Togo, West Africa. Over the course of 12 months, 13 distinct QI activities in Pediatric HIV/AIDS care delivery were monitored, and 11 of those activities met or exceeded established targets. Examples included: increase in infants receiving routine polymerase chain reaction testing at 2 months (39-95%), increase in HIV exposed children receiving confirmatory HIV testing at 18 months (67-100%), and increase in patients receiving initial CD4 testing within 3 months of HIV diagnosis (67-100%). The CDVC was an effective approach for evaluating existing systems and prioritizing gaps in delivery for QI over the full cycle of Pediatric HIV/AIDS care in three specific ways: (1) facilitating the first comprehensive mapping of Pediatric HIV/AIDS services, (2) identifying gaps in available services, and (3) catalyzing the creation of a responsive QI plan. The CDVC provided a framework to drive meaningful, strategic action to improve Pediatric HIV care in Togo.

  18. Impact of free delivery care on health facility delivery and insurance coverage in Ghana's Brong Ahafo Region.

    Susie Dzakpasu

    Full Text Available BACKGROUND: Many sub-Saharan countries, including Ghana, have introduced policies to provide free medical care to pregnant women. The impact of these policies, particularly on access to health services among the poor, has not been evaluated using rigorous methods, and so the empirical basis for defending these policies is weak. In Ghana, a recent report also cast doubt on the current mechanism of delivering free care--the National Health Insurance Scheme. Longitudinal surveillance data from two randomized controlled trials conducted in the Brong Ahafo Region provided a unique opportunity to assess the impact of Ghana's policies. METHODS: We used time-series methods to assess the impact of Ghana's 2005 policy on free delivery care and its 2008 policy on free national health insurance for pregnant women. We estimated their impacts on facility delivery and insurance coverage, and on socioeconomic differentials in these outcomes after controlling for temporal trends and seasonality. RESULTS: Facility delivery has been increasing significantly over time. The 2005 and 2008 policies were associated with significant jumps in coverage of 2.3% (p = 0.015 and 7.5% (p<0.001, respectively after the policies were introduced. Health insurance coverage also jumped significantly (17.5%, p<0.001 after the 2008 policy. The increases in facility delivery and insurance were greatest among the poorest, leading to a decline in socioeconomic inequality in both outcomes. CONCLUSION: Providing free care, particularly through free health insurance, has been effective in increasing facility delivery overall in the Brong Ahafo Region, and especially among the poor. This finding should be considered when evaluating the impact of the National Health Insurance Scheme and in supporting the continuation and expansion of free delivery care.

    studied care pathways. General practitioners/family doctors are responsible for liaising between different teams/services, except in Greece where this is done through pulmonologists. Ireland and the UK are the only countries with services for patients at home to shorten unnecessary hospital stay. HCPs emphasized lack of communication, limited resources, and poor patient engagement as issues in the current pathways. Furthermore, no specified role exists for pharmacists and informal carers.Conclusion: Service and professional integration between care settings using a unified system targeting COPD and comorbidities is a priority. Better communication between health care providers, establishing a clear role for informal carers, and enhancing patients’ engagement could optimize current care pathways resulting in a better integrated system.

    The advent of nanomedicine marks an unparalleled opportunity to advance the treatment of various diseases, including cancer. The unique properties of nanoparticles (NPs), such as large surface-to-volume ratio, small size, the ability to encapsulate various drugs, and tunable surface chemistry, give them many advantages over their bulk counterparts. This includes multivalent surface modification with targeting ligands, efficient navigation of the complex in vivo environment, increased intracellular trafficking, and sustained release of drug payload. These advantages make NPs a mode of treatment potentially superior to conventional cancer therapies. This review highlights the most recent developments in cancer treatment using NPs as drug delivery vehicles, including promising opportunities in targeted and combination therapy.

    Full Text Available Different mechanisms in cancer cells become resistant to one or more chemotherapeutics is known as multidrug resistance(MDR which hinders chemotherapy efficacy. Potential factors for MDR includes enhanced drug detoxification, decreased drug uptake, increased intracellular nucleophiles levels, enhanced repair of drug induced DNA damage, overexpression of drug transporter such as P-glycoprotein(P-gp, multidrug resistance-associated proteins(MRP1, MRP2 and breast cancer resistance protein(BCRP. Currently nanoassemblies such as polymeric/solid lipid/inorganic/metal nanoparticles, quantum dots, dendrimers, liposomes, micelles has emerged as an innovative, effective and promising platforms for treatment of drug resistant cancer cells. Nanocarriers have potential to improve drug therapeutic index, ability for multifunctionality, divert ABC-transporter mediated drug efflux mechanism and selective targeting to tumor cells, cancer stem cells, tumor initiating cells or cancer microenvironment. Selective nanocarrier targeting to tumor overcomes dose-limiting side effects, lack of selectivity, tissue toxicity, limited drug access to tumor tissues, high drug doses and emergence of multiple drug resistance with conventional or combination chemotherapy. Current review highlights various nanodrug delivery systems to overcome mechanism of MDR by neutralizing, evading or exploiting the drug efflux pumps and those independent of drug efflux pump mechanism by silencing Bcl-2 and HIF1 gene expressions by siRNA and miRNA, modulating ceramide levels and targeting NF-B. Theragnostics combining a cytotoxic agent, targeting moiety, chemosensitizing agent and diagnostic imaging aid are highlighted as effective and innovative systems for tumor localization and overcoming MDR. Physical approaches such as combination of drug with thermal/ultrasound/photodynamic therapies to overcome MDR are focused. The review focuses on newer drug delivery systems developed to overcome

    Full Text Available Although the “war on cancer” is now in its fourth decade and despite much progress has been made in categorizing the environmental causes and cellular and molecular biological basis for this dreaded disease, we still do not have a precise understanding of the differences between a cancer cell and its normal counterpart. If we do not understand cancer, we cannot control, conquer, and eliminate it. The completion of the human genome sequence and its subsequent improvements in the sequence data are important steps to fully comprehend cancer cell biology. Nanotechnology, a new, novel focus of research evolved from the convergence and coalescence of many diverse scientific disciplines and as a general term for the creation, manipulation, and application of structures in the nanometer size range. In this article, Nano medicine aspects of nanotechnology will be stressed and will cover areas such as drug delivery systems and new drug therapies as they relate to cancer. One of the ultimate goals of Nano medicine is to create medically useful Nano devices that can function inside the body. It is envisioned that Nano devices will be hybrids of biologic molecules and synthetic polymers that can enter cells and the organelles to interact directly with DNA and proteins. Additionally, Nano medicine will have an impact on the key challenges in cancer therapy: localized drug delivery and specific targeting. Among the newly developed Nano medicine and Nano devices such as quantum dots, nanowires, nanotubes, Nano cantilevers, and Nano pores, Nano shells and nanoparticles are the most promising applications for various cancer treatments.

    2014-01-01

    Our aim with this article is to develop a typology for the analysis of client-caregiver encounters in health care. We first observed client-caregiver interactions in the homes of home care clients and during the care processes of surgical patients. We then conducted a data-driven analysis to identify the clients' initiatives and the degree of engagement in the responses they received. The clients shaped their care by commenting on, questioning, ensuring, and enriching their care. The responses from the caregivers consisted of neutral acceptance, disregard, and shared expansive development of the clients' initiatives. The typology developed from these will be a tool to widen our understanding of the complex interactions in care delivery and of the different conceptualizations of care that actors hold. In future studies this typology will help in the analysis of the organizational dynamics of health care delivery.

    Informal/family caregivers are a fundamental source of care for cancer patients in the United States, yet the population of caregivers and their tasks, psychosocial needs, and health outcomes are not well understood. Changes in the nature of cancer care and its delivery, along with the growing population of survivors and their caregivers, warrant increased attention to the roles and demands of caregiving. This article reviews current evidence presented at a 2-day meeting examining the state of the science of informal cancer caregiving that was convened by the National Cancer Institute and the National Institute of Nursing Research. The meeting sought to define who is an informal cancer caregiver, summarize the state of the science in informal cancer caregiving, and describe both the kinds of interventions developed to address caregiving challenges and the various outcomes used to evaluate their impact. This article offers recommendations for moving science forward in 4 areas: 1) improving the estimation of the prevalence and burden of informal cancer caregiving; 2) advancing the development of interventions designed to improve outcomes for cancer patients, caregivers, and patient-caregiver dyads; 3) generating and testing strategies for integrating caregivers into formal health care settings; and 4) promoting the use of technology to support informal cancer caregivers.

    The scope of nanotechnology to develop target specific carriers to achieve higher therapeutic efficacy is gaining importance in the pharmaceutical and other industries. Specifically, the emergence of nanohybrid materials is posed to edge over chemotherapy and radiation therapy as cancer therapeutics. This is primarily because nanohybrid materials engage controlled production parameters in the making of engineered particles with specific size, shape, and other essential properties. It is widely expressed that these materials will significantly contribute to the next generation of medical care technology and pharmaceuticals in areas of disease diagnosis, disease prevention and many other treatment procedures. This review focuses on the currently used nanohybrid materials, polymeric nanoparticles and nanotubes, which show great potential as effective drug delivery systems for cancer therapy, as they can be grafted with cell-specific receptors and intracellular targeting molecules for the targeted delivery of therapeutics. Specifically, this article focuses on the current status, recent advancements, potentials and limitations of polymeric nanohybrids and functionalized carbon nanotubes as drug delivery carriers.

    A recent report from the Institute of Medicine titled Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis, identifies improvement in information technology (IT) as essential to improving the quality of cancer care in America. The report calls for implementation of a learning healthcare IT system: a system that supports patient-clinician interactions by providing patients and clinicians with the information and tools necessary to make well informed medical decisions and to support quality measurement and improvement. While some elements needed for a learning healthcare system are already in place for cancer, they are incompletely implemented, have functional deficiencies, and are not integrated in a way that creates a true learning healthcare system. To achieve the goal of a learning cancer care delivery system, clinicians, professional organizations, government, and the IT industry will have to partner, develop, and incentivize participation.

The aim of the study is to analyse experiences and preferences of bereaved relatives to terminally ill cancer patients in a primary care setting to explore barriers and facilitators for delivery of good palliative home care. Methods Three focus group interviews with fourteen bereaved relatives in Aarhus County, Denmark. Results Three main categories of experience were identified: 1 The health professionals' management, where a need to optimize was found. 2 Shared care, which was lacking. 3 The relatives' role, which needs an extra focus. Conclusion Relatives experience insufficient palliative care mainly due to organizational and cultural problems among professionals. Palliative care in primary care in general needs improvement and attention should be drawn to the "professionalization" of the relatives and the need to strike a balance between their needs, wishes and resources in end-of-life care and bereavement.

    2008-03-01

    Cultural competence in oncology requires the acquisition of specific knowledge, clinical skills, and attitudes that facilitate effective cross-cultural negotiation in the clinical setting, thus, leading to improved therapeutic outcomes and decreased disparities in cancer care. Cultural competence in oncology entails a basic knowledge of different cultural attitudes and practices of communication of the truth and of decision-making styles throughout the world. Cultural competence always presupposes oncology professionals' awareness of their own cultural beliefs and values. To be able to communicate with cancer patients in culturally sensitive ways, oncologists should have knowledge of the concept of culture in its complexity and of the risks of racism, classism, sexism, ageism, and stereotyping that must be avoided in clinical practice. Oncologists should develop a sense of appreciation for differences in health care values, based on the recognition that no culture can claim hegemony over others and that cultures are evolving under their reciprocal influence on each other. Medical schools and oncology training can teach communication skills and cultural competence, while fostering in all students and young doctors those attitudes of humility, empathy, curiosity, respect, sensitivity, and awareness that are needed to deliver effective and culturally sensitive cancer care.

    cancer survivors (>65 years) are especially vulnerable to poor outcomes in survivorship because of the complexity of follow-up care and other chronic conditions. Delivering written treatment summaries, written follow-up care plans, and verbal explanations of follow-up care plans all independently increased the self-efficacy for chronic illness management among older survivors. In particular, delivering this information in the verbal format was significantly associated with higher self-efficacy and, subsequently, a lower likelihood of emergency room visits. Understanding the mechanism through which summaries and follow-up care plans may positively influence survivor health is critical to increasing the delivery of the information. PMID:27245567

    Conventional chemotherapeutics have been employed in cancer treatment for decades due to their efficacy in killing the malignant cells, but the other side of the coin showed off-target effects, onset of drug resistance and recurrences. To overcome these limitations, different approaches have been investigated and suicide gene therapy has emerged as a promising alternative. This approach consists in the introduction of genetic materials into cancerous cells or the surrounding tissue to cause cell death or retard the growth of the tumor mass. Despite promising results obtained both in vitro and in vivo, this innovative approach has been limited, for long time, to the treatment of localized tumors, due to the suboptimal efficiency in introducing suicide genes into cancer cells. Nanoparticles represent a valuable non-viral delivery system to protect drugs in the bloodstream, to improve biodistribution, and to limit side effects by achieving target selectivity through surface ligands. In this scenario, the real potential of suicide genes can be translated into clinically viable treatments for patients. In the present review, we summarize the recent advances of inorganic nanoparticles as non-viral vectors in terms of therapeutic efficacy, targeting capacity and safety issues. We describe the main suicide genes currently used in therapy, with particular emphasis on toxin-encoding genes of bacterial and plant origin. In addition, we discuss the relevance of molecular targeting and tumor-restricted expression to improve treatment specificity to cancer tissue. Finally, we analyze the main clinical applications, limitations and future perspectives of suicide gene therapy.

  19. Pancreatic Cancer Gene Therapy: From Molecular Targets to Delivery Systems

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The continuous identification of molecular changes deregulating critical pathways in pancreatic tumor cells provides us with a large number of novel candidates to engineer gene-targeted approaches for pancreatic cancer treatment. Targets—both protein coding and non-coding—are being exploited in gene therapy to influence the deregulated pathways to facilitate cytotoxicity, enhance the immune response or sensitize to current treatments. Delivery vehicles based on viral or non-viral systems as well as cellular vectors with tumor homing characteristics are a critical part of the design of gene therapy strategies. The different behavior of tumoral versus non-tumoral cells inspires vector engineering with the generation of tumor selective products that can prevent potential toxic-associated effects. In the current review, a detailed analysis of the different targets, the delivery vectors, the preclinical approaches and a descriptive update on the conducted clinical trials are presented. Moreover, future possibilities in pancreatic cancer treatment by gene therapy strategies are discussed.

    Utilization of single-walled carbon nanotubes (SWCNTs) as more effective drug-delivery agents are being considered due to their ability to easily cross cell membranes, while their high aspect ratio and large surface area provide multiple attachment sites for biocompatible drug complexes. However, excessive bundling of pristine SWCNTs caused by strong attractive Van der Walls forces between CNT sidewalls is a major obstacle. We have successfully dispersed SWCNTs with both polyvinyl alcohol and Pluronic biocompatible polymers, and attached anti-cancer drugs Camptothecin (CPT) and Doxorubicin to form non-covalent CNT-polymer-drug conjugates in aqueous solution. Polymeric dispersion of SWCNTs by both polymers is confirmed by clearly identifiable near-infrared (NIR) fluorescence emission peaks of individual (7,5) and (7,6) nanotubes, and drug attachment to form complete complexes verified by UV-Vis spectroscopy. These complexes, with varying SWCNT and drug concentrations, were tested for effectiveness by exposing them to a line of human embryonic kidney cancer cells and analyzed for cell viability. Preliminary results indicate significant improvement in drug effectiveness on the cancer cells, with more successful internalization due to unaltered SWCNTs as the drug carriers.

The management model of the Provider Service Network empowers local physician groups with information and education. To meet the managed care information needs of the network, we implemented an intranet-based executive information system, PSNWeb, which retrieves data from a managed care data warehouse. The project required the integration of diverse technologies and development of a complex security/confidentiality infrastructure to deliver information to 8 major clinician groups, each with different information needs.

    The 1999 Institute of Medicine report Ensuring Quality Cancer Care discussed the difference between the actual cancer care received in the United States and the care that the patients should get, as well as some points to consider in delivering optimum care. In 2012, a follow-up review article in the journal Cancer entitled "Ensuring quality cancer care" indicated that there had been some interval progress, but more are needed to be done. The 2013 Institute of Medicine report Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis indicated that there are continuing major problems with cancer care and that they advocated a national system of quality reporting and a major information technology system to capture and help assess the data.

    Lung cancer is the commonest cause of cancer-related death worldwide and poses a significant respiratory disease burden. Little is known about the provision of lung cancer care across Europe. The overall aim of the Task Force was to investigate current practice in lung cancer care across Europe. The Task Force undertook four projects: 1) a narrative literature search on quality management of lung cancer; 2) a survey of national and local infrastructure for lung cancer care in Europe; 3) a benchmarking project on the quality of (inter)national lung cancer guidelines in Europe; and 4) a feasibility study of prospective data collection in a pan-European setting. There is little peer-reviewed literature on quality management in lung cancer care. The survey revealed important differences in the infrastructure of lung cancer care in Europe. The European guidelines that were assessed displayed wide variation in content and scope, as well as methodological quality but at the same time there was relevant duplication. The feasibility study demonstrated that it is, in principle, feasible to collect prospective demographic and clinical data on patients with lung cancer. Legal obligations vary among countries. The European Initiative for Quality Management in Lung Cancer Care has provided the first comprehensive snapshot of lung cancer care in Europe.

    In this study, the key exemplar processes of care in facilities with good resident outcomes were described. It follows that with description of these processes, it is feasible to teach facilities about the basics of care and the ways to systematically approach care so they can adopt these care processes and improve resident outcomes. However, for this to happen key organizational commitments must be in place for staff to consistently provide the basics of care. Nursing leadership must have a consistent presence over time, they must be champions of using team and group processes involving staff throughout the facility, and they must actively guide quality improvement processes. Administrative leadership must be present and express the expectation that high quality care is expected for residents, and that workers are expected to contribute to the quality improvement effort. If facilities are struggling with achieving average or poor resident outcomes, they must first make an effort to find nursing and administrative leaders who are willing to stay with the organization. These leaders must be skilled with team and group processes for decision-making and how to implement and use a quality improvement program to improve care. These leaders must be skilled at building employee relations and at retention strategies so residents are cared for by consistent staff who know them. The results of this study illustrate the simplicity of the basics of care that residents in nursing facilities need. The results also illustrate the complexity of the care processes and the organizational systems that must be in place to achieve good outcomes. Achieving these outcomes is the challenge facing those currently working in and leading nursing facilities.

    Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it. We focus on five factors applicable to cancer care delivery: familiarity, clinical hierarchy-related status differences, geographic dispersion, boundary spanning, and leader behavior. To illustrate how these factors facilitate or hinder psychologically safe communication and teamwork in cancer care, we review the case of a patient as she experiences the treatment-planning process for early-stage breast cancer in a community setting. Our analysis is summarized in a key principle: Teamwork in cancer care requires high-quality communication, which depends on psychological safety for all team members, clinicians and patients alike. We conclude with a discussion of the implications of psychological safety in clinical care and suggestions for future research.

  10. Single-walled carbon nanotube and graphene: Nano-delivery of Gambogic acid increases its cytotoxicty in various cancer cells

    Science.gov (United States)

    Saeed, Lamya M.

    Nanomedicine is a new branch of medicine that has been developed due to the critical need to treat challenging diseases, especially cancer since it remains a significant cause of morbidity and mortality worldwide and the second most common cause of death after heart disease in the USA. One of the most important health care applications of nanomedicine concerns the development of drug delivery systems. Graphene (Gn), an atom-thick carbon monolayer of sp2- bonded carbon atoms arranged in a two dimensional (2D) honeycomb crystal lattice, and single-walled carbon nanotubes (SWCNTs) (1D, tubular) are among the most promising nanomaterials with the capability of delivering drugs or small therapeutic molecules to cancerous cells. For example, they have been used as vehicles for the anti-cancer, low-toxicity drug Gambogic acid (GA). Here, the cytotoxicity of GA in breast (MCF-7), pancreatic (PANC-1), cervical (HELA), ovarian (NCI/ADR), and prostate (PC3) cancer cells was assessed to determine what effect nanodelivery by either Gn or SWCNTs had on the efficacy of this promising drug. The nanomaterials showed no toxicity at the concentrations used. The inhibition of cell proliferation and apoptosis of the cells was due to the effects of GA which was significantly enhanced by nanodelivery. Such delivery of GA by either Gn or SWCNTs represents a first step toward assessing their effectiveness in more complex, targeted nano-delivery in vivo settings and signals their potential application in the treatment of cancer.

    Full Text Available Introduction':' A remarkable difference in care delivery pathways for Chronic Obstructive Pulmonary Disease (COPD is the presence of hospital-at-home for COPD exacerbations in England and its absence in the Netherlands. The objective of this paper is to explain this difference. Methods':' Descriptive COPD statistics and care delivery pathways on all care levels within the institutional context, followed by a comparison of care delivery pathways and an explanation of the difference with regard to hospital-at-home. Results: The Netherlands and England show broad similarities in their care delivery pathways for COPD patients. A major difference is the presence of hospital-at-home for COPD exacerbations in England and its absence in the Netherlands. Three possible explanations for this difference are presented: differences in the urgency for alternatives (higher urgency for alternative treatment models in England, the differences in funding (funding in England facilitated the development of hospital-at-home and the differences in the substitution of tasks to nurses (substitution to nurses has taken place to a larger extent in England. Discussion and Conclusion: The difference between the Netherlands and England regarding hospital-at-home for COPD exacerbations can be explained in three ways. Hospital-at-home has proved to be a safe alternative for hospital care for selected patients, and should be considered as a treatment option for COPD exacerbations in the Netherlands.

    Gene-based immunization with transgenic DNA vectors expressing tumor-associated antigens (TAA), cytokines, or chemokines, alone or in combination, provides an attractive approach to increase the cytotoxic T cell immunity against various cancer diseases. With this consideration, particle-mediated or gene gun technology has been developed as a nonviral method for gene transfer into various mammalian tissues. It has been shown to induce both humoral and cell-mediated immune responses in both small and large experimental animals. A broad range of somatic cell types, including primary cultures and established cell lines, has been successfully transfected ex vivo or in vitro by gene gun technology, either as suspension or adherent cultures. Here, we show that protocols and techniques for use in gene gun-mediated transgene delivery system for skin vaccination against melanoma using tumor-associated antigen (TAA) human gpl00 and reporter gene assays as experimental systems.

    One of the main challenges in cancer research is the development of vaccines that induce effective and long-lived protective immunity against tumors. Significant progress has been made in identifying members of the cancer testis antigen family as potential vaccine candidates. However, an ideal form for antigen delivery that induces robust and sustainable antigen-specific T-cell responses, and in particular of CD8(+) T lymphocytes, remains to be developed. Here we report the use of a recombinant nonpathogenic clone of Trypanosoma cruzi as a vaccine vector to induce vigorous and long-term T cell-mediated immunity. The rationale for using the highly attenuated T. cruzi clone was (i) the ability of the parasite to persist in host tissues and therefore to induce a long-term antigen-specific immune response; (ii) the existence of intrinsic parasite agonists for Toll-like receptors and consequent induction of highly polarized T helper cell type 1 responses; and (iii) the parasite replication in the host cell cytoplasm, leading to direct antigen presentation through the endogenous pathway and consequent induction of antigen-specific CD8(+) T cells. Importantly, we found that parasites expressing a cancer testis antigen (NY-ESO-1) were able to elicit human antigen-specific T-cell responses in vitro and solid protection against melanoma in a mouse model. Furthermore, in a therapeutic protocol, the parasites expressing NY-ESO-1 delayed the rate of tumor development in mice. We conclude that the T. cruzi vector is highly efficient in inducing T cell-mediated immunity and protection against cancer cells. More broadly, this strategy could be used to elicit a long-term T cell-mediated immunity and used for prophylaxis or therapy of chronic infectious diseases.

    The pace and scale of globalization in health care services delivery have accelerated over the past decade. There have been numerous collaborations in health care service delivery between the private sector in North America and Europe with public and private entities in various emerging markets. These partnerships can be extremely fruitful, but also carry significant challenges. Johns Hopkins Medicine International (JHI) has been active for more than a decade in supporting international partners in building capacity and improving delivery systems. In addressing the challenges of globalization we have learned a number of lessons and have come up with several innovations to better help providers in emerging markets respond to the health care needs unique to their regions.

    Patient experience is one of key domains of value-based purchasing that can serve as a measure of quality and be used to improve the delivery of health services. The aims of this study are to explore patient perceptions of quality of health care and to understand how perceptions may differ by settings and condition. A systematic review of multiple databases was conducted for studies targeting patient perceptions of quality of care. Two reviewers screened and extracted data independently. Data synthesis was performed following a meta-narrative approach. A total of 36 studies were included that identified 10 quality dimensions perceived by patients: communication, access, shared decision making, provider knowledge and skills, physical environment, patient education, electronic medical record, pain control, discharge process, and preventive services. These dimensions can be used in planning and evaluating health care delivery. Future research should evaluate the effect of interventions targeting patient experience on patient outcomes.

    Health care enterprises make comprehensive and durable changes in people. This human-centered purpose defines the fundamental nature of quality in health care settings. Traditional perspectives of quality and familiar views of customer satisfaction are inadequate to manage the complex relationships between the health care delivery firm and its patients. Patients play four roles in health care systems that must be reflected when defining and measuring quality in these settings: patient as supplier, patient as product, patient as participant, and patient as recipient. This article presents a conceptual model of quality that incorporates these diverse patient roles. The strategic and managerial implications of the model are also discussed.

    Pancreatic cancer (PC) is one of the most deadly and quickly fatal human cancers with a 5-year mortality rate close to 100%. Its prognosis is very poor, mainly because of its hostile biological behavior and late onset of symptoms for clinical diagnosis; these bring limitations on therapeutic interventions. Factors contributing for the difficulties in treating PC include: high rate of drug resistance, fast metastasis to different organs, poor prognosis and relapse of the tumor after therapy. After being approved by US FDA 1997, Gemcitabine (Gem) is the first line and the gold standard drug for all stages of advanced PC till now. However, its efficacy is unsatisfactory, mainly due to; its chemical instability and poor cellular uptake, resulting in an extremely short half-life and low bioavailability. To solve this drawbacks and increase the therapeutic outcome important progress has been achieved in the field of nanotechnology and offers a promising and effective alternative. This review mainly focus on the most commonly investigated nanoparticle (NP) delivery systems of Gem for PC treatment and the latest progresses achieved. Novel nanocarriers with better tumor targeting efficiencies and maximum treatment outcome to treat this deadly due are given much attention.

    Full Text Available Objectives: To describe the implementation of a new model face to face and remote pharmaceutical care with home delivery of tyronsine kinase inhibitors medicines for patients with chronic myeloid leukemia. Methods: Patients with chronic myeloid leukemia were selected to start this new model of care. Four characteristics were taken into account for the choice: chronicity of the disease, frequency of doctor visits, pharmaceutical care value and conservation of tyronsine kinase inhibitors medicines at room temperature. Results: Out of 68 patients with chronic myeloid leukemia and treated with tyronsine kinase inhibitors, 42 were selected due to the frequency of their hematologist visits. An introductory letter and a questionnaire about their preferences were sent to these patients.Sixteen of them expressed their desire to participate. The legal department designed a confidentiality contract, as well as a model of informed consent. A logistic distribution model based on defined routes and timetables was established. Prior to inclusion, pharmaceutical care was performed in a face to face consultation and the communication way was established for the followings remote consultations. Home delivery had a monthly cost of 13.2 € (including VAT per patient. All the patients who started this program continue in it. To date, 5 deliveries per patient have been conducted Conclusions: It is possible to establish an alternative model of pharmaceutical care with home delivery of medication, keeping the pharmacist-patient relationship, avoiding travel, ensuring the confidentiality and rationalizing the stocks

    Nanotechnology is an emerging paradigm for creating functional nanoscale materials for various biomedical applications. In this study, a new nanotechnology-based drug delivery method was developed using gold nanoparticles (GNPs) as a delivery vehicle to reduce adverse drug side effects. Fludarabine Phosphate is a commercial chemotherapy drug used in cancer treatment, and has ability to kill various cancer cells. KG-1 cell, a type of acute cancer leukemia cell, was selected as a proof-of-concept target in this study. Due to the small size of GNPs, they can help Fludarabine Phosphate enter cancer cells more efficiently and better interfere with DNA synthesis in the cancer cells. To enhance targeting ability, folic acid molecules were also covalently linked to GNPs, resulting in GNP-Fludarabine-folic acid (GNP-F/f). Compared to treatments with GNP-F or drugs on its own (Fludarabine Phosphate), the GNP-F/f achieves much improved cell-killing effects. The UV-Vis spectra results also revealed that the drugs had successfully bonded covalently to the GNPs. The higher cell-killing efficiency of GNP-F/f compared with GNP-Fludarabine (GNP-F) or drugs on their own further validates the effectiveness of both the vectors (GNPs) and folic acid in enhancing the drug delivery to the cancer cells. The MTT viability tests showed that the GNPs had no cytotoxicity.

    2014-09-01

    Care coordination models have developed in response to the recognition that Australia's health and welfare service system can be difficult to access, navigate and is often inefficient in caring for people with severe and persistent mental illness (SPMI) and complex care and support needs. This paper explores how the Australian Government's establishment of the Partners in Recovery (PIR) initiative provides an opportunity for the development of more effective and efficient models of coordinated care for the identified people with SPMI and their families and carers. In conceptualising how the impact of the PIR initiative could be maximised, the paper explores care coordination and what is known about current best practice. The key findings are the importance of having care coordinators who are well prepared for the role, can demonstrate competent practice and achieve better systemic responses focused on the needs of the client, thus addressing the barriers to effective care and treatment across complex service delivery systems.

    Full Text Available Interprofessional education (IPE is an activity that involves two or more professions who learn interactively together to improve collaboration and the quality of care. Research has continually revealed that health and social care professionals encounter a range of problems with interprofessional coordination and collaboration which impact on the quality and safety of care. This empirical work resulted in policymakers across health care education and practice to invest in IPE to help resolve this collaborative failures. It is anticipated that IPE will provide health and social care professionals with the abilities required to work together effectively in providing safe high quality care to patients. Through a discussion of a range of key professional, educational and organization issues related to IPE, this paper argues that this form of education is an important strategy to improve the delivery of safe and effective care

    Full Text Available Abstract Background About 98% of newborn deaths occur in developing countries, where most newborns deaths occur at home. In Nepal, approximately, 90% of deliveries take place at home. Information about reasons for delivering at home and newborn care practices in urban areas of Nepal is lacking and such information will be useful for policy makers. Methods A cross-sectional survey was carried out in the immunisation clinics of Pokhara city, western Nepal during January and February, 2006. Two trained health workers administered a semi-structured questionnaire to the mothers who had delivered at home. Results A total of 240 mothers were interviewed. Planned home deliveries were 140 (58.3% and 100 (41.7% were unplanned. Only 6.2% of deliveries had a skilled birth attendant present and 38 (15.8% mothers gave birth alone. Only 46 (16.2% women had used a clean home delivery kit and only 92 (38.3% birth attendants had washed their hands.

    Digital engagement has become pervasive in the delivery of cancer care. Internet- and cellular phone-based tools and systems are allowing large groups of people to engage with each other and share information. Health systems and individual health professionals are adapting to this revolution in consumer and patient behavior by developing ways to incorporate the benefits of technology for the purpose of improving the quality of medical care. One example is the use of social media platforms by oncologists to foster interaction with each other and to participate with the lay public in dialogue about science, medicine, and cancer care. In addition, consumer devices and sensors (wearables) have provided a new, growing dimension of digital engagement and another layer of patient-generated health data to foster better care and research. Finally, electronic health records have become the new standard for oncology care delivery, bringing new opportunities to measure quality in real time and follow practice patterns, as well as new challenges as providers and patients seek ways to integrate this technology along with other forms of digital engagement to produce more satisfaction in the process of care along with measurably better outcomes.

    Noscapine, a tubulin binding anticancer agent undergoing Phase I/II clinical trials, inhibits tumor growth in nude mice bearing human xenografts of breast, lung, ovarian, brain, and prostrate origin. The analogues of noscapine like 9-bromonoscapine (EM011) are 5 to 10-fold more active than parent compound, noscapine. Noscapinoids inhibit the proliferation of cancer cells that are resistant to paclitaxel and epothilone. Noscapine also potentiated the anticancer activity of doxorubicin in a synergistic manner against triple negative breast cancer (TNBC). However, physicochemical and pharmacokinetic (ED50˜300-600 mg/kg bodyweight) limitations of noscapine present hurdle in development of commercial anticancer formulations. Therefore, objectives of the present review are to summarize the chemotherapeutic potential of noscapine and implications of nanoscale based drug delivery systems in enhancing the therapeutic efficacy of noscapine in cancer cells. We have constructed noscapine-enveloped gelatin nanoparticles, NPs and poly (ethylene glycol) grafted gelatin NPs as well as inclusion complex of noscapine in β-cyclodextrin (β-CD) and evaluated their physicochemical characteristics. The Fe3O4 NPs were also used to incorporate noscapine in its polymeric nanomatrix system where molecular weight of the polymer governed the encapsulation efficiency of drug. The enhanced noscapine delivery using μPAR-targeted optical-MR imaging trackable NPs offer a great potential for image directed targeted delivery of noscapine. Human Serum Albumin NPs (150-300 nm) as efficient noscapine drug delivery systems have also been developed for potential use in breast cancer.

    2015-01-01

    By its nature, retail medicine is founded in real estate. That retail medicine has expanded so dramatically in a relatively short period of time has taken people by surprise. This rapid growth of integrating healthcare services into retail real estate begs the question of whether real estate will eventually take on the importance in healthcare delivery that it has in retail. This article advances the view that it will. In the end, what retail and healthcare have in common is that they both reflect the attributes of demanding consumers as part of an experience-based economy, where products and services are sought based on how they fit with their lifestyles and how they make them feel (Pine and Gilmore 1998). Changing the selection process for healthcare services to be more like retail is already expanding how and where healthcare services are delivered.

    There is no clear understanding about the concept of technology adoption in the health-care environment. Compatibility is one of the factors affecting telehealth adoption. We investigated the key factors of telehealth's compatibility with health centre activities. Qualitative research was carried out in 2007-2009, with 55 interviews in seven health centres and in one special care hospital. The people interviewed were physicians, nurses and physiotherapists. After analysing the interview material, we concluded that compatibility has three aspects: individual, process and organizational compatibility. Individual compatibility was manifested in four different ways: from the viewpoints of professionals, patients, communication and cooperation. Three aspects of process compatibility were introduced: scheduling, resources and complexity of processes. Modest organizing efforts with telehealth and even a lack of interest can be expressions of organizational compatibility. Functional and user-friendly technology is a basic precondition for telehealth compatibility. With thorough organizing, most of the compatibility challenges can be solved.

    This research examines individual and area level factors associated with maternal health care utilization in Pakistan. The 2012-2013 Pakistan Demographic and Health Surveys data was used to model five outcomes: prenatal care within the first trimester, four plus prenatal visits, birth attendance by a skilled attendant, birth in a medical facility, and receipt of postnatal care. Less than half of births were to mothers receiving prenatal care in the first trimester, and approximately 57 % had trained personnel at delivery. Over half were born to mothers who received postnatal care. Evidence was found to support the positive effect of individual level variables, education and wealth, on the utilization of maternal health care across all five measures. Although, this study did not find unilateral differences between women residing in rural and urban settings, rural women were found to have lower odds of utilizing prenatal services as compared to mothers in urban environments. Additionally, women who cited distance as a barrier, had lower odds of receiving postnatal health care, but still engaged in prenatal services and often had a skilled attendant present at delivery. The odds of utilizing prenatal care increased when women resided in an area where prenatal utilization was high, and this variability was found across measures across provinces. The results found in this paper highlight the uneven progress made around improving prenatal, delivery, and postnatal care in Pakistan; disparities persist which may be attributed to factors both at the individual and community level, but may be addressed through a consorted effort to change national policy around women's health which should include the promotion of evidence based interventions such as incentivizing health care workers, promoting girls' education, and improving transportation options for pregnant women and recent mothers with the intent of ultimately lowering the Maternal Mortality Rate as recommended in the U

    2005-05-01

    Advances in the biomedical and the behavioral sciences have paved the way for the integration of medical practice towards the biopsychosocial approach. Therefore, dealing with health and illness overtakes looking for the presence or absence of the disease and infirmity (the biomedical paradigm) to the biopsychosocial paradigm in which health means a state of complete physical, psychological and social well-being. Psychology as a behavioral health discipline is the key to the biopsychosocial practice, and plays a major role in understanding the concept of health and illness. The clinical role of psychologists as health providers is diverse with the varying areas of care giving (primary, secondary and tertiary care) and a variety of subspecialties. Overall, psychologists assess, diagnose, and treat the psychological problems and the behavioral dysfunctions resulting from, or related to physical and mental health. In addition, they play a major role in the promotion of healthy behavior, preventing diseases and improving patients' quality of life. They perform their clinical roles according to rigorous ethical principles and code of conduct. This article describes and discusses the significant role of clinical health psychology in the provision of health care, following a biopsychosocial perspective of health and illness. Professional and educational issues have also been discussed.

    The involvement of non-government organizations (NGOs) and support groups has helped strengthen public health services in addressing cancer care burden. Owing to the contribution of volunteers in cancer care, this article documents a qualitative study that examined challenges in attracting and retaining cancer care volunteers as part of the effort to develop a volunteer recruitment model. Data were collected through three focus group discussions involving 19 cancer support group members in Malaysia. Findings of the study revealed that mobility and locality appeared to be significant in Malaysian context, while the need for financial support and time flexibility are challenges faced by cancer support groups to attract and retain volunteers. The findings imply that cancer care initiatives can benefit from more local volunteers but at the same time these volunteers require flexibility and financial support to sustain their engagement.

  4. Diet and Nutrition in Cancer Survivorship and Palliative Care

    Full Text Available The primary goal of palliative cancer care is typically to relieve suffering and improve quality of life. Most approaches to diet in this setting have focused only on eating as many calories as possible to avoid cachexia. However, as the concept of palliative care has evolved to include all aspects of cancer survivorship and not just end of life care, there is an increasing need to thoughtfully consider diet and nutrition approaches that can impact not only quality of life but overall health outcomes and perhaps even positively affect cancer recurrence and progression. In this regard, there has been a recent emphasis in the literature on nutrition and cancer as an important factor in both quality of life and in the pathophysiology of cancer. Hence, the primary purpose of this paper is to review the current data on diet and nutrition as it pertains to a wide range of cancer patients in the palliative care setting.

    Full Text Available BACKGROUND: As part of the mid-term evaluation of a Women's Health Care Project, a study was conducted to compare the utilization of maternal and neonatal health (MNH services in two areas with different levels of service in Punjab, Pakistan. METHODS: A cross-sectional survey was conducted to interview Married Women of Reproductive Age (MWRA. Information was collected on MWRA knowledge regarding danger signs during pregnancy, delivery, postnatal periods, and MNH care seeking behavior. After comparing MNH service utilization, the two areas were compared using a logistic regression model, to identify the association of different factors with the intervention after controlling for socio-demographic, economic factors and distance of the MWRA residence to a health care facility. RESULTS: The demographic characteristics of women in the two areas were similar, although socioeconomic status as indicated by level of education and better household amenities, was higher in the intervention area. Consequently, on univariate analysis, utilization of MNH services: antenatal care, TT vaccination, institutional delivery and use of modern contraceptives were higher in the intervention than control area. Nonetheless, multivariable analysis controlling for confounders such as socioeconomic status revealed that utilization of antenatal care services at health centers and TT vaccination during pregnancy are significantly associated with the intervention. CONCLUSIONS: Our findings suggest positive changes in health care seeking behavior of women and families with respect to MNH. Some aspects of care still require attention, such as knowledge about danger signs and neonatal care, especially umbilical cord care. Despite overall success achieved so far in response to the Millennium Development Goals, over the past two decades decreases in maternal mortality are far from the 2015 target. This report identifies some of the key factors to improving MNH and serves as an

    2010-02-01

    Full Text Available The aim of this study was to develop a classic grounded theory of palliative cancer patients and their relatives in the context of home care. We analyzed interviews and data related to the behaviour of both patients and relatives. “Living on hold” emerged as the pattern of behaviour through which the patients and relatives deal with their main concern, being put on hold. Living on Hold involves three modes: Fighting, Adjusting and Surrendering. Mode being may change during a trajectory depending on many different factors. There are also different triggers that can start a reconciling process leading to a change of mode. This means that patients and relatives can either be in the same mode or in different modes simultaneously. More or less synchronous modes may lead to problems and conflicts within the family, or with the health professionals.

    1986-02-01

    Serum prolactin has been determined in 334 patients with breast cancer within the radiooncologic care. In addition 54 healthy female blood donors were analysed as controls. Values above 600 mU/l were called hyperprolactinemic. 15% of the patients showed elevated prolactin levels, 25% of which coincided with recurrent disease. Preoperative evaluation of prolactin in combination with TPA and CEA may be an aid in selecting a special group of patients with poor prognosis. Following 31 patients under therapy it could be demonstrated that any successful treatment modality leads to a normalization of elevated prolactin levels. In refractory cases addition of bromocriptine may be effective. Furthermore, drug induced hyperprolactinemia ought to be treated.

    1998-01-01

    Under the auspices of the Buffalo General Hospital and the faculty of medicine of the State University of New York at Buffalo, a comprehensive delivery system for primary care has been established in a local inner-city neighborhood. At the Deaconess Family Medicine Center, located within an inner-city location of Buffalo, New York, several divisions have been integrated to provide comprehensive patient-oriented primary care. These divisions include a primary care clinic, an urgent care clinic, a substance abuse clinic, and a community pediatrics clinic. Professional services are provided by attending physicians and residents. The horizontal integration of these four divisions is in turn vertically integrated with the tertiary care teaching hospital inpatient and obstetrical services, providing a continuum of patient care. The horizontal integration serves as an entry point for patients to enter the hospital's health-care system, while the vertical integration capability serves to capture any specialized referrals or inpatient needs. This article discusses the structure of the center, with special reference to service integration, service delivery, and patient capture; medical education; and the place of integrated units in the strategic plan of a tertiary care hospital.

    Asian Americans experience disproportionate incidence and mortality rates of certain cancers, compared to other racial/ethnic groups. Primary care physicians are a critical source for cancer screening recommendations and play a significant role in increasing cancer screening of their patients. This study assessed primary care physicians' perceptions of cancer risk in Asians and screening recommendation practices. Primary care physicians practicing in New Jersey and New York City (n=100) completed a 30-question survey on medical practice characteristics, Asian patient communication, cancer screening guidelines, and Asian cancer risk. Liver cancer and stomach cancer were perceived as higher cancer risks among Asian Americans than among the general population, and breast and prostate cancer were perceived as lower risks. Physicians are integral public health liaisons who can be both influential and resourceful toward educating Asian Americans about specific cancer awareness and screening information.

    Ghandourh, Wsam A

    2016-12-01

    Advanced cancer patients commonly have misunderstandings about the intentions of treatment and their overall prognosis. Several studies have shown that large numbers of patients receiving palliative radiation or chemotherapy hold unrealistic hopes of their cancer being cured by such therapies, which can affect their ability to make well-informed decisions about treatment options. This review aimed to explore this discrepancy between patients' and physicians' expectations by investigating three primary issues: (1) the factors associated with patients developing unrealistic expectations; (2) the implications of having unrealistic hopes and the effects of raising patients' awareness about prognosis; and (3) patients' and caregivers' perspective on disclosure and their preferences for communication styles. Relevant studies were identified by searching electronic databases including Pubmed, EMBASE and ScienceDirect using multiple combinations of keywords, which yielded a total of 65 articles meeting the inclusion criteria. The discrepancy between patients' and doctors' expectations was associated with many factors including doctors' reluctance to disclose terminal prognoses and patients' ability to understand or accept such information. The majority of patients and caregivers expressed a desire for detailed prognostic information; however, varied responses have been reported on the preferred style of conveying such information. Communication styles have profound effects on patients' experience and treatment choices. Patients' views on disclosure are influenced by many cultural, psychological and illness-related factors, therefore individuals' needs must be considered when conveying prognostic information. More research is needed to identify communication barriers and the interventions that could be used to increase patients' satisfaction with palliative care.

    2013-06-01

    Full Text Available Health and social care systems are implementing fundamental changes to organizational structures and work practices in an effort to achieve integrated care. While some integration initiatives have produced positive outcomes, many have not. We reframe the concept of integration as a learning process fueled by knowledge exchange across diverse professional and organizational communities. We thus focus on the cognitive and social dynamics of learning in complex adaptive systems, and on learning behaviours and conditions that foster collective learning and improved collaboration. We suggest that the capacity to learn how to learn shapes the extent to which diverse professional groups effectively exchange knowledge and self-organize for integrated care delivery.

    Disruptive innovation has brought affordability and convenience to customers in a variety of industries. However, health care remains expensive and inaccessible to many because of the lack of business-model innovation. This paper explains the theory of disruptive innovation and describes how disruptive technologies must be matched with innovative business models. The authors present a framework for categorizing and developing business models in health care, followed by a discussion of some of the reasons why disruptive innovation in health care delivery has been slow.

    Breast cancer during pregnancy (BCP), although rare, is becoming more common and treatment should be as similar as possible to that for nonpregnant young patients with breast cancer. A group of specialists convened to review current guidelines and provide guidance on how recent advances in breast cancer diagnosis and treatment can be adapted for pregnant patients. The majority of patients with BCP will be considered for treatment during the pregnancy. Premature delivery should be avoided whenever possible. Most treatments, including sentinel lymph node biopsy, systemic therapy with taxanes, platinum agents, or dose-dense treatment can be safely given during pregnancy, after careful risk/benefit assessment for mother and child. Chemotherapy is contraindicated during the first trimester because of a higher risk of fetal malformations but is feasible in the second and third trimesters. Other treatments such as radiation therapy or anti-human epidermal growth receptor 2 treatment are in general not indicated during pregnancy but might be considered in some instances. Patient data should be collected in a systematic way whenever possible.

    1995-09-01

    This paper outlines the role of quality audit within the framework of quality assurance, presenting the concurrent and retrospective approaches available. The literature survey provides a review of the limited audit tools available and their application to continence services and care delivery, as well as attempts to produce tools from national and local standard setting. Audit is part of a process; it can involve staff, patients and their relatives and the team of professionals providing care, as well as focusing on organizational and management levels. In an era of market delivery of services there is a need to justify why audit is important to continence advisors and managers. Effectiveness, efficiency and economics may drive the National Health Service, but quality assurance, which includes standards and audit tools, offers the means to ensure the quality of continence services and care to patients and auditing is also required in the purchaser/provider contracts for patient services. An overview and progress to date of published and other a projects in auditing continence care and service is presented. By outlining and highlighting the audit of continence service delivery and care as a basis on which to build quality assurance programmes, it is hoped that this knowledge will be shared through the setting up of a central auditing clearing project.

    Hui, David; Bruera, Eduardo

    2016-03-01

    Over the past five decades, palliative care has evolved from serving patients at the end of life into a highly specialized discipline focused on delivering supportive care to patients with life-limiting illnesses throughout the disease trajectory. A growing body of evidence is now available to inform the key domains in the practice of palliative care, including symptom management, psychosocial care, communication, decision-making, and end-of-life care. Findings from multiple studies indicate that integrating palliative care early in the disease trajectory can result in improvements in quality of life, symptom control, patient and caregiver satisfaction, illness understanding, quality of end-of-life care, survival, and costs of care. In this narrative Review, we discuss various strategies to integrate oncology and palliative care by optimizing clinical infrastructures, processes, education, and research. The goal of integration is to maximize patient access to palliative care and, ultimately, to improve patient outcomes. We provide a conceptual model for the integration of supportive and/or palliative care with primary and oncological care. We also discuss how health-care systems and institutions need to tailor integration based on their resources, size, and the level of primary palliative care available.

  4. Policy challenges for the pediatric rheumatology workforce: Part II. Health care system delivery and workforce supply

    2011-08-01

    Full Text Available Abstract The United States pediatric population with chronic health conditions is expanding. Currently, this demographic comprises 12-18% of the American child and youth population. Affected children often receive fragmented, uncoordinated care. Overall, the American health care delivery system produces modest outcomes for this population. Poor, uninsured and minority children may be at increased risk for inferior coordination of services. Further, the United States health care delivery system is primarily organized for the diagnosis and treatment of acute conditions. For pediatric patients with chronic health conditions, the typical acute problem-oriented visit actually serves as a barrier to care. The biomedical model of patient education prevails, characterized by unilateral transfer of medical information. However, the evidence basis for improvement in disease outcomes supports the use of the chronic care model, initially proposed by Dr. Edward Wagner. Six inter-related elements distinguish the success of the chronic care model, which include self-management support and care coordination by a prepared, proactive team. United States health care lacks a coherent policy direction for the management of high cost chronic conditions, including rheumatic diseases. A fundamental restructure of United States health care delivery must urgently occur which places the patient at the center of care. For the pediatric rheumatology workforce, reimbursement policies and the actions of health plans and insurers are consistent barriers to chronic disease improvement. United States reimbursement policy and overall fragmentation of health care services pose specific challenges for widespread implementation of the chronic care model. Team-based multidisciplinary care, care coordination and self-management are integral to improve outcomes. Pediatric rheumatology demand in the United States far exceeds available workforce supply.

    2008-05-01

    Full Text Available Abstract Background There is still debate as to which features, types or components of primary care interventions are associated with improved depression outcomes. Previous reviews have focused on components of collaborative care models in general practice settings. This paper aims to determine the effective components of depression care in primary care through a systematic examination of both general practice and community based intervention trials. Methods Fifty five randomised and controlled research trials which focused on adults and contained depression outcome measures were identified through PubMed, PsycInfo and the Cochrane Central Register of Controlled Trials databases. Trials were classified according to the components involved in the delivery of treatment, the type of treatment, the primary focus or setting of the study, detailed features of delivery, and the discipline of the professional providing the treatment. The primary outcome measure was significant improvement on the key depression measure. Results Components which were found to significantly predict improvement were the revision of professional roles, the provision of a case manager who provided direct feedback and delivered a psychological therapy, and an intervention that incorporated patient preferences into care. Nurse, psychologist and psychiatrist delivered care were effective, but pharmacist delivery was not. Training directed to general practitioners was significantly less successful than interventions that did not have training as the most important intervention. Community interventions were effective. Conclusion Case management is important in the provision of care in general practice. Certain community models of care (education programs have potential while others are not successful in their current form (pharmacist monitoring.

    The emergence of nanotechnology has changed the scenario of the medical world by revolutionizing the diagnosis, monitoring and treatment of cancer. This nanotechnology has been proved miraculous in detecting cancer cells, delivering chemotherapeutic agents and monitoring treatment from non-specific to highly targeted killing of tumor cells. In the past few decades, a number of inorganic materials have been investigated such as calcium phosphate, gold, carbon materials, silicon oxide, iron oxide, and layered double hydroxide (LDH) for examining their efficacy in targeting drug delivery. The reason behind the selection of these inorganic materials was their versatile and unique features efficient in drug delivery, such as wide availability, rich surface functionality, good biocompatibility, potential for target delivery, and controlled release of the drug from these inorganic nanomaterials. Although, the drug-LDH hybrids are found to be quite instrumental because of their application as advanced anti-cancer drug delivery systems, there has not been much research on them. This mini review is set to highlight the advancement made in the use of layered double hydroxides (LDHs) as anti-cancer drug delivery agents. Along with the advantages of LDHs as anti-cancer drug delivery agents, the process of interaction of some of the common anti-cancer drugs with LDH has also been discussed.

    As cancer is the leading cause of death worldwide, every nurse will be required to care for patients with the condition at some point in his\\/her career. However, non-specialized oncology nurses are often ill-prepared to nurse patients suffering from cancer. This literature review aims to provide an overview of current trends and developments in cancer care nursing in an attempt to identify the range of previous research pertaining to caring for patients with cancer on non-specialist wards. The review finds that non-specialized cancer nurses report a lack of education and training with regard to cancer care and cancer treatments, which acts as a barrier to providing quality nursing care. Emotional and communication issues with patients and their families can also cause non-specialist nurses significant distress. International research has shown that specialist oncology nurses make a considerable difference to physical and psychosocial patient care. It is therefore paramount that non-speciality nurses\\' educational needs are met to develop clinical competence and to provide supportive holistic care for both patients and their families.

    Purpose This paper describes the implementation of an innovative program that aims to improve postpartum care through a set of coordinated delivery and payment system changes designed to use postpartum care as an opportunity to impact the current and future health of vulnerable women and reduce disparities in health outcomes among minority women. Description A large health care system, a Medicaid managed care organization, and a multidisciplinary team of experts in obstetrics, health economics, and health disparities designed an intervention to improve postpartum care for women identified as high-risk. The program includes a social work/care management component and a payment system redesign with a cost-sharing arrangement between the health system and the Medicaid managed care plan to cover the cost of staff, clinician education, performance feedback, and clinic/clinician financial incentives. The goal is to enroll 510 high-risk postpartum mothers. Assessment The primary outcome of interest is a timely postpartum visit in accordance with NCQA healthcare effectiveness data and information set guidelines. Secondary outcomes include care process measures for women with specific high-risk conditions, emergency room visits, postpartum readmissions, depression screens, and health care costs. Conclusion Our evidence-based program focuses on an important area of maternal health, targets racial/ethnic disparities in postpartum care, utilizes an innovative payment reform strategy, and brings together insurers, researchers, clinicians, and policy experts to work together to foster health and wellness for postpartum women and reduce disparities.

    As states' Medicaid programs continue to evolve from traditional fee-for-service to value-based health care delivery, there is growing recognition that systemwide multipayer approaches provide the market power needed to address the triple aim of improved patient care, improved health of populations, and reduced costs. Federal initiatives, such as the State Innovation Model grant program, make significant funds available for states seeking to transform their health care systems. In crafting their reform strategies, states can learn from early innovators. This issue brief focuses on one such state: Arkansas. Insights and lessons from the Arkansas Health Care Payment Improvement Initiative (AHCPII) suggest that progress is best gained through an inclusive, deliberative process facilitated by committed leadership, a shared agreement on root problems and opportunities for improvement, and a strategy grounded in the state's particular health care landscape.

    For more than half a century neonatologists and ethicists alike have struggled with ethical dilemmas surrounding infants born at the limits of viability. Both doctors and parents face difficult decisions. Do we try to save these babies, knowing that such efforts are likely to be unsuccessful? Or do we provide only comfort care, knowing that, in doing so, you will inevitably allow some babies to die who might have been saved? In this paper, we review the outcome data on these babies and offer ten suggestions for doctors: (1) accept that there is a 'gray zone' during which decisions are not black and white; (2) do not place too much emphasis on gestational age; (3) dying is generally not in an infant's best interest; (4) impairment does not necessarily equal poor quality of life; (5) just because the train has left the station doesn't mean you can't get off; (6) respect powerful emotions; (7) be aware of the self-fulfilling prophecies; (8) time lag likely skews all outcome data; (9) statistics can be both confused and confusing; (10) never abandon parents.

    Full Text Available Purpose: Women with breast cancer have complex and unique gynecologic needs that are challenging to effectively and comprehensively meet in a traditional gynecology visit format. Group medical visits are an effective and well-received model of care in other disease settings and can provide comprehensive health education as an adjunct to one-on-one evaluation and treatment. There are limited data regarding the use of this type of health care delivery in providing gynecology-focused care to women affected by breast cancer. Methods: A group medical visit model was created for gynecology providers to see new breast cancer patient consults. From May 2012 to February 2014, 148 patients (3–6 per group participated in a 1-hour informational session followed by a 15- to 30-minute individual visit with a physician that included history, physical examination and evaluation. We surveyed 101 women who attended these visits to evaluate a group model for providing gynecologic care and educational support to women with breast cancer. Results: Of those who responded to the survey question, 100% agreed or somewhat agreed that their expectations for an initial intake visit were met during the group visit; 81% agreed or somewhat agreed that they felt a group visit was preferable to an individual introductory visit. More than 95% agreed or somewhat agreed that the information was understandable and their questions were answered during the visit. Only 5 respondents expressed dissatisfaction with the additional time commitment for this type of visit. Conclusions: The majority of women surveyed expressed satisfaction with their experience with a group visit format. The women who participated preferred this format compared to an individual intake appointment when establishing gynecology care after breast cancer diagnosis/treatment, regardless of age, menopausal status, cancer stage or hormone receptor status. While further studies are warranted to directly compare and

    New, comprehensive, approaches for chronic disease management are needed to ensure that patients, particularly those more likely to experience health disparities, have access to the clinical care, self-management resources, and support necessary for the prevention and control of diabetes. Community health workers (CHWs) have worked in community settings to reduce health care disparities and are currently being deployed in some clinical settings as a means of improving access to and quality of care. Guided by the chronic care model, Baylor Health Care System embedded CHWs within clinical teams in community clinics with the goal of reducing observed disparities in diabetes care and outcomes. This study examines findings from interviews with patients, CHWs, and primary care providers (PCPs) to understand how health care delivery systems can be redesigned to effectively incorporate CHWs and how embedding CHWs in primary care teams can produce informed, activated patients and prepared, proactive practice teams who can work together to achieve improved patient outcomes. Respondents indicated that the PCPs continued to provide clinical exams and manage patient care, but the roles of diabetes education, nutritional counseling, and patient activation were shifted to the CHWs. CHWs also provided patients with social support and connection to community resources. Integration of CHWs into clinical care teams improved patient knowledge and activation levels, the ability of PCPs to identify and proactively address specific patient needs, and patient outcomes.

  13. Facility Delivery, Postnatal Care and Neonatal Deaths in India: Nationally-Representative Case-Control Studies.

    Full Text Available Clinical studies demonstrate the efficacy of interventions to reduce neonatal deaths, but there are fewer studies of their real-life effectiveness. In India, women often seek facility delivery after complications arise, rather than to avoid complications. Our objective was to quantify the association of facility delivery and postnatal checkups with neonatal mortality while examining the "reverse causality" in which the mothers deliver at a health facility due to adverse perinatal events.We conducted nationally representative case-control studies of about 300,000 live births and 4,000 neonatal deaths to examine the effect of, place of delivery and postnatal checkup on neonatal mortality. We compared neonatal deaths to all live births and to a subset of live births reporting excessive bleeding or obstructed labour that were more comparable to cases in seeking care.In the larger study of 2004-8 births, facility delivery without postnatal checkup was associated with an increased odds of neonatal death (Odds ratio = 2.5; 99% CI 2.2-2.9, especially for early versus late neonatal deaths. However, use of more comparable controls showed marked attenuation (Odds ratio = 0.5; 0.4-0.5. Facility delivery with postnatal checkup was associated with reduced odds of neonatal death. Excess risks were attenuated in the earlier study of 2001-4 births.The combined effect of facility deliveries with postnatal checks ups is substantially higher than just facility delivery alone. Evaluation of the real-life effectiveness of interventions to reduce child and maternal deaths need to consider reverse causality. If these associations are causal, facility delivery with postnatal check up could avoid about 1/3 of all neonatal deaths in India (~100,000/year.

    Objective Healthcare reforms in the United States, including the Affordable Care and HITECH Acts, and the NCQA criteria for the Patient Centered Medical Home have promoted health information technology (HIT) and the integration of general medical and mental health services. These developments, which aim to improve chronic disease care have largely occurred in parallel, with little attention to the need for coordination. In this article, the fundamental connections between HIT and improvements in chronic disease management are explored. We use the evidence-based collaborative care model as an example, with attention to health literacy improvement for supporting patient engagement in care. Method A review of the literature was conducted to identify how HIT and collaborative care, an evidence-based model of chronic disease care, support each other. Results Five key principles of effective collaborative care are outlined: care is patient-centered, evidence-based, measurement-based, population-based, and accountable. The potential role of HIT in implementing each principle is discussed. Key features of the mobile health paradigm are described, including how they can extend evidence-based treatment beyond traditional clinical settings. Conclusion HIT, and particularly mobile health, can enhance collaborative care interventions, and thus improve the health of individuals and populations when deployed in integrated delivery systems.

    Recent progress in RNA biology has broadened the scope of therapeutic targets of RNA drugs for cancer therapy. However, RNA drugs, typically small interfering RNAs (siRNAs), are rapidly degraded by RNases and filtrated in the kidney, thereby requiring a delivery vehicle for efficient transport to the target cells. To date, various delivery formulations have been developed from cationic lipids, polymers, and/or inorganic nanoparticles for systemic delivery of siRNA to solid tumors. This review describes the current status of clinical trials related to siRNA-based cancer therapy, as well as the remaining issues that need to be overcome to establish a successful therapy. It, then introduces various promising design strategies of delivery vehicles for stable and targeted siRNA delivery, including the prospects for future design.

    Background: Disparities in lung cancer treatment and palliative care are well documented. However, the mechanisms underlying these disparities are not fully understood. In this study, we evaluated racial and ethnic differences in beliefs and attitudes about lung cancer treatment and palliative care among patients receiving a new diagnosis of lung cancer. Methods: Patients were recruited from four medical centers in New York City and surveyed about their beliefs regarding lung cancer care, including disease-directed treatments, palliative and end-of-life care, and fatalistic and spiritual beliefs. We used univariate and multiple regression analyses to compare the distribution of beliefs among minority (black and Hispanic) and nonminority patients. Results: Of the 335 patients, 21% were black, 20% were Hispanic, and 59% were nonminority. Beliefs about chemotherapy and radiotherapy were similar across the three groups (P > .05), whereas black patients were more likely to believe that surgery might cause lung cancer to spread (P = .008). Fatalistic beliefs potentially affecting cancer treatment were more common among both minority groups (P ≤ .02). No significant differences were found in attitudes toward clinician communication about cancer prognosis (P > .05). However, both blacks and Hispanics were more likely to have misconceptions about advance directives and hospice care (P ≤ .02). Conclusions: Similarities and differences in beliefs about disease-directed treatment were observed between minority and nonminority patients with lung cancer. Minority patients hold more fatalistic views about the disease and misperceptions about advance care planning and hospice care. Further research is needed to assess the impact of these beliefs on decisions about lung cancer care and patient outcomes. PMID:22700777

    Full Text Available Abstract Background In 2003, the Ethiopian Ministry of Health launched the Health Extension Programme (HEP, which was intended to increase access to reproductive health care. Despite enormous effort, utilization of maternal health services remains limited, and the reasons for the low utilization of the services offered through the HEP previously have not been explored in depth. This study explores women’s experiences and perceptions regarding delivery care in Tigray, a northern region of Ethiopia, and enables us to make suggestions for better implementation of maternal health care services in this setting. Methods We used six focus group discussions with 51 women to explore perceptions and experiences regarding delivery care. The data were analysed by means of grounded theory. Results One core category emerged, ‘making pragmatic choices’, which connected the categories ‘aiming for safer deliveries’, ‘embedded in tradition’, and ‘medical knowledge under constrained circumstances’. In this setting, women – aiming for safer deliveries – made choices pragmatically between the two available models of childbirth. On the one hand, choice of home delivery, represented by the category ‘embedded in tradition’, was related to their faith, the ascendancy of elderly women, the advantages of staying at home and the custom of traditional birth attendants (TBAs. On the other, institutional delivery, represented by the category ‘medical knowledge under constrained circumstances’, and linked to how women appreciated medical resources and the support of health extension workers (HEWs but were uncertain about the quality of care, emphasized the barriers to transportation. In Tigray women made choices pragmatically and seemed to not feel any conflict between the two available models, being supported by traditional birth attendants, HEWs and husbands in their decision-making. Representatives of the two models were not as open to

    Significant symptoms and suffering related to castrate-resistant prostate cancer (CRPC) are associated with the disease and its treatment. Increasingly, with advances in treatment efficacy, men can live with symptoms for long periods. Interdisciplinary palliative care teams (including physicians, nurses, social workers, chaplains, pharmacists, psychologists, physical therapists, and nutritionists) focused on symptom management and patients' goals of care can collaborate with prostate cancer surgeons, oncologists, and radiation oncologists to provide the best care for men at all stages of treatment, including end of life. This article reviews the benefits of palliative care in helping patients with CRPC manage symptoms and distress.

    Quality cancer treatment depends upon careful coordination between multiple treatments and treatment providers, the exchange of technical information, and regular communication between all providers and physician disciplines involved in treatment. This article will examine a particular type of organizational structure purported to regularize and streamline the communication between multiple specialists and support services involved in cancer treatment: the multidisciplinary treatment care (MDC) team. We present a targeted review of what is known about various types of MDC team structures and their impact on the quality of treatment care, and we outline a conceptual model of the connections between team context, structure, process, and performance and their subsequent effects on cancer treatment care processes and patient outcomes. Finally, we will discuss future research directions to understand how MDC teams improve patient outcomes and how characteristics of team structure, culture, leadership, and context (organizational setting and local environment) contribute to optimal multidisciplinary cancer care.

  2. Value Assessment at the Point of Care: Incorporating Patient Values throughout Care Delivery and a Draft Taxonomy of Patient Values.

    Armstrong, Melissa J; Mullins, C Daniel

    2017-02-01

    Incorporation of patient values is a key element of patient-centered care, but consistent incorporation of patient values at the point of care is lacking. Shared decision making encourages incorporation of patient values in decision making, but associated tools often lack guidance on value assessment. In addition, focusing on patient values relating only to specific decisions misses an opportunity for a more holistic approach to value assessment that could impact other aspects of clinical encounters, including health care planning, communication, and stakeholder involvement. In this commentary, we propose a taxonomy of values underlying patient decision making and provide examples of how these impact provision of health care. The taxonomy describes four categories of patient values: global, decisional, situational, and external. Global values are personal values impacting decision making at a universal level and can include value traits and life priorities. Decisional values are the values traditionally conceptualized in decision making, including considerations such as efficacy, toxicity, quality of life, convenience, and cost. Situational values are values tied to a specific moment in time that modify patients' existing global and decisional values. Finally, discussion of external values acknowledges that many patients consider values other than their own when making decisions. Recognizing the breadth of values impacting patient decision making has implications for both overall health care delivery and shared decision making because value assessments focusing only on decisional values may miss important patient considerations. This draft taxonomy highlights different values impacting decision making and facilitates a more complete value assessment at the point of care.

    The concept of optimizing health care by understanding and generating knowledge from previous evidence, ie, the Learning Health-care System (LHS), has gained momentum and now has national prominence. Meanwhile, the rapid adoption of electronic health records (EHRs) enables the data collection required to form the basis for facilitating LHS. A prerequisite for using EHR data within the LHS is an infrastructure that enables access to EHR data longitudinally for health-care analytics and real time for knowledge delivery. Additionally, significant clinical information is embedded in the free text, making natural language processing (NLP) an essential component in implementing an LHS. Herein, we share our institutional implementation of a big data-empowered clinical NLP infrastructure, which not only enables health-care analytics but also has real-time NLP processing capability. The infrastructure has been utilized for multiple institutional projects including the MayoExpertAdvisor, an individualized care recommendation solution for clinical care. We compared the advantages of big data over two other environments. Big data infrastructure significantly outperformed other infrastructure in terms of computing speed, demonstrating its value in making the LHS a possibility in the near future.

    At the government, hospital, and health-care provider level, corruption plays a major role in health-care systems in Africa. The returns on health investments of international financial institutions, health organisations, and donors might be very low when mismanagement and dysfunctional structures of health-care systems are not addressed. More funding might even aggravate corruption. We discuss corruption and its effects on cancer care within the African health-care system in a sociocultural context. The contribution of high-income countries in stimulating corruption is also described. Corrupt African governments cannot be expected to take the initiative to eradicate corruption. Therefore, international financial institutions, health organisations, and financial donors should use their power to demand policy reforms of health-care systems in Africa troubled by the issue of corruption. These modifications will ameliorate the access and quality of cancer care for patients across the continent, and ultimately improve the outcome of health care to all patients.

    Full Text Available Purpose: To propose an integration index of home care delivery to older persons, to study its validity and to apply it to home care services of European cities. Theory: Home care delivery integration was based on two dimensions referring to process-centred integration and organisational structure approach. Method: Items considered as part of both dimensions according to an expert consensus (face validity were extracted from a standardised questionnaire used in “Aged in Home care” (AdHoc study to capture basic characteristics of home care services. Their summation leads to a services' delivery integration index. This index was applied to AdHoc services. A factor analysis was computed in order to empirically test the validity of the theoretical constructs. The plot of the settings was performed. Results: Application of the index ranks home care services in four groups according to their score. Factor analysis identifies a first factor which opposes working arrangement within service to organisational structure bringing together provisions for social care. A second factor corresponds to basic nursing care and therapies. Internal consistency for those three domains ranges from 0.78 to 0.93. When plotting the different settings different models of service delivery appear. Conclusion: The proposed index shows that behind a total score several models of care delivery are hidden. Comparison of service delivery integration should take into account this heterogeneity.

    Providing care to adolescents with cancer in the process of death and dying has been a great challenge for health professionals. This challenge is marked by a high emotional burden and specificities of this stage of human development. The purpose of the present study was to review the scientific literature regarding palliative care to adolescents with cancer. This study is a literature review, which data collection was performed using Lilacs, Medline, and PsycInfo, in addition to non-systematic databases. An analysis of the manuscripts revealed three themes: adolescence and its different definitions; the particularities of adolescents with cancer; and palliative care to adolescents with cancer. The study showed there is a scarcity of evidenced-based research defining the panorama of symptoms affecting the quality of life during palliative care and an absence of specific programs in the stage of fast changes that, alone, demand for adaptive efforts.

    Background The Medicare accountable care organization (ACO) programs rely on delivery system integration and provider risk sharing to lower spending while improving quality of care. Methods Using 2009 Medicare claims and linked American Medical Association Group Practice data, we assigned 4.29 million beneficiaries to provider groups based on primary care use. We categorized group size according to eligibility thresholds for the Shared Savings (≥5,000 assigned beneficiaries) and Pioneer (≥15,000) ACO programs and distinguished hospital-based from independent groups. We compared spending and quality of care between larger and smaller provider groups and examined how size-related differences varied by 2 factors considered central to ACO performance: group primary care orientation (measured by the primary care share of large groups’ specialty mix) and provider risk sharing (measured by county health maintenance organization penetration and its relationship to financial risk accepted by different group types for managed care patients). Spending and quality of care measures included total medical spending, spending by type of service, 5 process measures of quality, and 30-day readmissions, all adjusted for sociodemographic and clinical characteristics. Results Compared with smaller groups, larger hospital-based groups had higher total per-beneficiary spending in 2009 (mean difference: +$849), higher 30-day readmission rates (+1.3% percentage points), and similar performance on 4 of 5 process measures of quality. In contrast, larger independent physician groups performed better than smaller groups on all process measures and exhibited significantly lower per-beneficiary spending in counties where risk sharing by these groups was more common (−$426). Among all groups sufficiently large to participate in ACO programs, a strong primary care orientation was associated with lower spending, fewer readmissions, and better quality of diabetes care. Conclusions Spending

    Hopkinson, Jane B

    2015-11-01

    Cancer cachexia is a complex syndrome. Its defining feature is involuntary weight loss, which arises, in part, because of muscle atrophy and is accompanied by functional decline. International expert consensus recommends that nutritional support and counselling is a component of multimodal therapy for cancer cachexia, as poor nutritional intake can contribute to progression of the syndrome. The present paper focuses on what is presently known about the nursing contribution to nutritional care in cancer cachexia. There is potential for nurses to play an important role. However, obstacles to this include lack of a robust evidence base to support their nutritional care practices and unmet need for education about nutrition in cancer. The nursing role's boundaries and the outcomes of nurse-delivered nutritional care in cancer cachexia are both uncertain and should be investigated.

Service quality was calculated using: Service Quality = 10 – (Importance × Performance based on importance and performance of service quality aspects from the postpartum women‟s perspective.A hierarchical regression analysis was applied in two steps using the enter method to examine the associations between demographics and SQ scores. Data were analysed using the SPSS-17 software. Results: “Confidentiality”, “autonomy”, “choice of care provider” and “communication” achieved scores at the highest level of quality; and “support group”, “prompt attention”, “prevention and early detection”, “continuity of care”, “dignity”, “safety”, “accessibility and “basic amenities” got service quality score less than eight. Statistically significant relationship was found between service quality score and continuity of care (P=0.008. Conclusion: A notable gap between the participants‟ expectations and what they have actually received in most aspects of provided care. So, there is an opportunityto improve the quality of delivered care.

    Health care systems have utilized various process redesign methodologies to improve care delivery. This article describes the creation of a novel process improvement methodology, Rapid Process Optimization (RPO). This system was used to redesign emergency care delivery within a large academic health care system, which resulted in a decrease: (1) door-to-physician time (Department A: 54 minutes pre vs 12 minutes 1 year post; Department B: 20 minutes pre vs 8 minutes 3 months post), (2) overall length of stay (Department A: 228 vs 184; Department B: 202 vs 192), (3) discharge length of stay (Department A: 216 vs 140; Department B: 179 vs 169), and (4) left without being seen rates (Department A: 5.5% vs 0.0%; Department B: 4.1% vs 0.5%) despite a 47% increased census at Department A (34 391 vs 50 691) and a 4% increase at Department B (8404 vs 8753). The novel RPO process improvement methodology can inform and guide successful care redesign.

    TNFα-related apoptosis-inducing ligand (TRAIL) induces death selectively in cancer cells. However, subpopulations of cancer cells are either resistant to or can develop resistance to TRAIL-induced death. As a result, strategies that overcome this resistance are currently under investigation. We have recently identified several US FDA-approved drugs with TRAIL-sensitization activity against prostate, breast and pancreatic cancer cells. Mitoxantrone, a previously unknown TRAIL sensitizer identified in the screen, was successfully encapsulated in methoxy-, amine- and carboxyl-terminated PEG-DSPE micelles in order to facilitate delivery of the drug to cancer cells. All three micelle types were extensively characterized for their physicochemical properties and evaluated for their ability to sensitize cancer cells to TRAIL-induced death. Our results indicate that micelle-encapsulated mitoxantrone can be advantageously employed in synergistic treatments with TRAIL, leading to a biocompatible delivery system and amplified cell killing activity for combination chemotherapeutic cancer treatments.

    The purpose of this study is to explore the factors associated with outsourcing of information systems (IS) in hospital-based health care delivery systems, and to determine if there is a difference in IS outsourcing activity based on the strategic value of the outsourced functions. IS sourcing behavior is conceptualized as a case of vertical integration. A synthesis of strategic management theory (SMT) and transaction cost economics (TCE) serves as the theoretical framework. The sample consists of 1,365 hospital-based health care delivery systems that own 3,452 hospitals operating in 2004. The findings indicate that neither TCE nor SMT predicted outsourcing better than the other did. The findings also suggest that health care delivery system managers may not be considering significant factors when making sourcing decisions, including the relative strategic value of the functions they are outsourcing. It is consistent with previous literature to suggest that the high cost of IS may be the main factor driving the outsourcing decision.

    Full Text Available Abstract Background Increasingly, women in India attend health facilities for childbirth, partly due to incentives paid under government programs. Increased use of health facilities can alleviate the risks of infections contracted in unhygienic home deliveries, but poor infection control practices in labour and delivery units also cause puerperal sepsis and other infections of childbirth. A needs assessment was conducted to provide information on procedures and practices related to infection control in labour and delivery units in Gujarat state, India. Methods Twenty health care facilities, including private and public primary health centres and referral hospitals, were sampled from two districts in Gujarat state, India. Three pre-tested tools for interviewing and for observation were used. Data collection was based on existing infection control guidelines for clean practices, clean equipment, clean environment and availability of diagnostics and treatment. The study was carried out from April to May 2009. Results Seventy percent of respondents said that standard infection control procedures were followed, but a written procedure was only available in 5% of facilities. Alcohol rubs were not used for hand cleaning and surgical gloves were reused in over 70% of facilities, especially for vaginal examinations in the labour room. Most types of equipment and supplies were available but a third of facilities did not have wash basins with "hands-free" taps. Only 15% of facilities reported that wiping of surfaces was done immediately after each delivery in labour rooms. Blood culture services were available in 25% of facilities and antibiotics are widely given to women after normal delivery. A few facilities had data on infections and reported rates of 3% to 5%. Conclusions This study of current infection control procedures and practices during labour and delivery in health facilities in Gujarat revealed a need for improved information systems

    Full Text Available Abstract Background Australia's Aboriginal and Torres Strait Islander (Indigenous populations have disproportionately high rates of adverse perinatal outcomes relative to other Australians. Poorer access to good quality maternal health care is a key driver of this disparity. The aim of this study was to describe patterns of delivery of maternity care and service gaps in primary care services in Australian Indigenous communities. Methods We undertook a cross-sectional baseline audit for a quality improvement intervention. Medical records of 535 women from 34 Indigenous community health centres in five regions (Top End of Northern Territory 13, Central Australia 2, Far West New South Wales 6, Western Australia 9, and North Queensland 4 were audited. The main outcome measures included: adherence to recommended protocols and procedures in the antenatal and postnatal periods including: clinical, laboratory and ultrasound investigations; screening for gestational diabetes and Group B Streptococcus; brief intervention/advice on health-related behaviours and risks; and follow up of identified health problems. Results The proportion of women presenting for their first antenatal visit in the first trimester ranged from 34% to 49% between regions; consequently, documentation of care early in pregnancy was poor. Overall, documentation of routine antenatal investigations and brief interventions/advice regarding health behaviours varied, and generally indicated that these services were underutilised. For example, 46% of known smokers received smoking cessation advice/counselling; 52% of all women received antenatal education and 51% had investigation for gestational diabetes. Overall, there was relatively good documentation of follow up of identified problems related to hypertension or diabetes, with over 70% of identified women being referred to a GP/Obstetrician. Conclusion Participating services had both strengths and weaknesses in the delivery of maternal

    Purpose Despite the Institute of Medicine’s (IOM) 2005 recommendation, few care organizations have instituted standard survivorship care plans (SCPs). Low health literacy and low English proficiency are important factors to consider in SCP development. Our study aimed to identify information needs and survivorship care plan preferences of low literacy, multi-lingual patients to support the transition from oncology to primary care and ongoing learning in survivorship. Methods We conducted focus groups in five languages with African American, Latina, Russian, Filipina, White, and Chinese medically underserved breast cancer patients. Topics explored included the transition to primary care, access to information, knowledge of treatment history, and perspectives on SCPs. Results Analysis of focus group data identified three themes: 1) the need for information and education on the transition between “active treatment” and “survivorship”; 2) information needed (and often not obtained) from providers; and 3) perspectives on SCP content and delivery. Conclusions Our data point to the need to develop a process as well as written information for medically underserved breast cancer patients. An SCP document will not replace direct communication with providers about treatment, symptom management and transition, a communication that is missing in participating safety-net patients’ experiences of cancer care. Women turned to peer support and community-based organizations in the absence of information from providers. Implications for Cancer Survivors “Clear and effective” communication of survivorship care for safety-net patients requires dedicated staff trained to address wide-ranging information needs and uncertainties.

    Bone health and maintenance of bone integrity are important components of comprehensive cancer care. Many patients with cancer are at risk for therapy-induced bone loss, with resultant osteoporotic fractures, or skeletal metastases, which may result in pathologic fractures, hypercalcemia, bone pain, and decline in motility and performance status. Effective screening and timely interventions are essential for reducing bone-related morbidity. Management of long-term bone health requires a broad knowledge base. A multidisciplinary health care team may be needed for optimal assessment and treatment of bone-related issues in patients with cancer. Since publication of the previous NCCN Task Force Report: Bone Health in Cancer Care in 2009, new data have emerged on bone health and treatment, prompting NCCN to convene this multidisciplinary task force to discuss the progress made in optimizing bone health in patients with cancer. In December 2012, the panel members provided didactic presentations on various topics, integrating expert judgment with a review of the key literature. This report summarizes issues surrounding bone health in cancer care presented and discussed during this NCCN Bone Health in Cancer Care Task Force meeting.

  1. Novel therapeutic modalities and drug delivery in pancreatic cancer – an ongoing search for improved efficacy

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Pancreatic cancer is an incredibly challenging disease due to its high rates of resistance to traditional chemotherapy and radiotherapy. There has been little improvement in the prognosis of pancreatic cancer cases in the past decades, highlighting the crucial need for more effective therapeutic approaches. Erlotinib, an EGFR inhibitor, and gemcitabine, a nucleoside analog, are currently used in combination for chemotherapy treatment, but new developments in drug delivery systems using liposomes and nanoparticles may be promising new modalities for management of the disease. In addition to standard chemotherapeutic drugs, these delivery systems can be utilized to deliver therapeutic agents such as siRNA, oncolytic viruses, small molecule inhibitors, antibodies, and suicide genes. Further work is required to elucidate how ligands and antibodies could be used to enhance the targeted delivery of drugs, thus increasing specificity, improving stability, and reducing the effect of the drugs on healthy tissue. Despite significant preclinical data, there are currently very few clinical trials involving pancreatic cancer targeted drug delivery. This article summarizes current developments in targeted pancreatic cancer drug delivery, focusing on delivery systems, targets, and therapeutic agents.

    During recent years, significant development has been achieved in carbon nanotube conjugated with polymer system for drug delivery system (DDS). In the present study, we have prepared functionalized single walled carbon nanotube conjugated with chitooligosaccharide (f-SWNT-COS) as a Drug Delivery System. In addition, drug Gliotoxin (GTX) and targeting molecules (Lysozyme, p53 and Folic acid) have been incorporated into f-SWNT-COS. f-SWNTs-COS-GTX-p53, f-SWNTs-COS-GTX-lysozyme, f-SWNTs-COS-GTX-FA have been physiochemically characterized for DDS. FT-IR, SEM and TEM analysis confirmed the formation of chemical interaction and polymer coating. FT-IR result clearly confirmed the interaction between f-SWNT and COS. The effective drug release was monitored against cervical cancer (HeLa) cells and Breast Cancer (MCF-7) cells and it was found that all the three drug delivery systems showed significant cytotoxicity. f-SWNTs-COS-GTX-p53 delivery vehicle and its effective cytotoxicity on HeLa cells was further checked with fluorescent activated cell sorter analysis. Our results suggest that the f-SWNTs-COS-GTX-p53 is the most effective delivery vehicle with a controlled release and enhanced cytotoxicity rendered through apoptosis in human cervical cancer (HeLa) cells. These systems can further be used for the delivery of other commercially available anti cancer drugs as well.

    Because of the advent of disease-modifying agents for patients with malignancies, cancer is now a chronic illness. However, most cancer patients will experience significant symptoms and complications during the course of their illness or its treatment. In addition to their physical symptoms, patient and families are burdened with psychological, social, and spiritual difficulties. Palliative medicine addresses all these issues and complements attempts to cure the disease; it is an essential part of modern comprehensive cancer care.

    Background COPD is among the leading causes of chronic morbidity and mortality in the European Union with an estimated annual economic burden of €25.1 billion. Various care pathways for COPD exist across Europe leading to different responses to similar problems. Determining these differences and the similarities may improve health and the functioning of health services. Objective The aim of this study was to compare COPD patients’ care pathway in five European Union countries including England, Ireland, the Netherlands, Greece, and Germany and to explore health care professionals’ (HCPs) perceptions about the current pathways. Methods HCPs were interviewed in two stages using a qualitative, semistructured email interview and a face-to-face semistructured interview. Results Lack of communication among different health care providers managing COPD and comorbidities was a common feature of the studied care pathways. General practitioners/family doctors are responsible for liaising between different teams/services, except in Greece where this is done through pulmonologists. Ireland and the UK are the only countries with services for patients at home to shorten unnecessary hospital stay. HCPs emphasized lack of communication, limited resources, and poor patient engagement as issues in the current pathways. Furthermore, no specified role exists for pharmacists and informal carers. Conclusion Service and professional integration between care settings using a unified system targeting COPD and comorbidities is a priority. Better communication between health care providers, establishing a clear role for informal carers, and enhancing patients’ engagement could optimize current care pathways resulting in a better integrated system.

    Despite the increasing availability of palliative care, oncology providers often misunderstand and underutilize these resources. The goals of palliative care are relief of suffering and provision of the best possible quality of life for both the patient and her family, regardless of where she is in the natural history of her disease. Lack of understanding and awareness of the services provided by palliative care physicians underlie barriers to referral. Oncologic providers spend a significant amount of time palliating the symptoms of cancer and its treatment; involvement of specialty palliative care providers can assist in managing the complex patient. Patients with gynecologic malignancies remain an ideal population for palliative care intervention. This review of the literature explores the current state of palliative care in the treatment of gynecologic cancers and its implications for the quality and cost of this treatment.

  7. Cost evaluation of reproductive and primary health care mobile service delivery for women in two rural districts in South Africa.

    Full Text Available Cervical cancer screening is a critical health service that is often unavailable to women in under-resourced settings. In order to expand access to this and other reproductive and primary health care services, a South African non-governmental organization established a van-based mobile clinic in two rural districts in South Africa. To inform policy and budgeting, we conducted a cost evaluation of this service delivery model.The evaluation was retrospective (October 2012-September 2013 for one district and April-September 2013 for the second district and conducted from a provider cost perspective. Services evaluated included cervical cancer screening, HIV counselling and testing, syndromic management of sexually transmitted infections (STIs, breast exams, provision of condoms, contraceptives, and general health education. Fixed costs, including vehicle purchase and conversion, equipment, operating costs and mobile clinic staffing, were collected from program records and public sector pricing information. The number of women accessing different services was multiplied by ingredients-based variable costs, reflecting the consumables required. All costs are reported in 2013 USD.Fixed costs accounted for most of the total annual costs of the mobile clinics (85% and 94% for the two districts; the largest contributor to annual fixed costs was staff salaries. Average costs per patient were driven by the total number of patients seen, at $46.09 and $76.03 for the two districts. Variable costs for Pap smears were higher than for other services provided, and some services, such as breast exams and STI and tuberculosis symptoms screening, had no marginal cost.Staffing costs are the largest component of providing mobile health services to rural communities. Yet, in remote areas where patient volumes do not exceed nursing staff capacity, incorporating multiple services within a cervical cancer screening program is an approach to potentially expand access to

    2015-01-01

    Accelerated by the Patient Protection and Affordable Care Act of 2010, health care delivery in the United States is poised to move from a model that rewards the volume of services provided to one that rewards the value provided by such services. Radiology department operations are currently managed by an array of metrics that assess various departmental missions, but many of these metrics do not measure value. Regulators and other stakeholders also influence what metrics are used to assess medical imaging. Metrics such as the Physician Quality Reporting System are increasingly being linked to financial penalties. In addition, metrics assessing radiology's contribution to cost or outcomes are currently lacking. In fact, radiology is widely viewed as a contributor to health care costs without an adequate understanding of its contribution to downstream cost savings or improvement in patient outcomes. The new value-based system of health care delivery and reimbursement will measure a provider's contribution to reducing costs and improving patient outcomes with the intention of making reimbursement commensurate with adherence to these metrics. The authors describe existing metrics and their application to the practice of radiology, discuss the so-called value equation, and suggest possible metrics that will be useful for demonstrating the value of radiologists' services to their patients.

  11. Health care delivery and change: thoughts on Lema's "... of dinosaurs, dodos and anesthesia personnel".

    Science.gov (United States)

    Gunn, I P

    1999-11-01

    Problems in health care delivery relative to access, costs, and quality have been debated for more than a quarter of a century. Health care costs have significantly increased since the implementation of the Medicare/Medicaid legislation. Cost containment has been high on the agendas of government officials, legislators, health policy decision makers, business leaders, and economists since the 1980s. There has been a shift toward market medicine and managed care as a means for cost containment. Although some costs were contained for a short period, they are once again rising significantly, and there is growing dissatisfaction with this shift. The United States is not alone in this dilemma. Mark Lema, MD, PHD, editor of the ASA Newsletter, wrote a thought-provoking editorial in the July 1999 issue, raising concerns about change, relationships, reimbursement, and demise relative to anesthesia personnel. In response, this article primarily raises the issue of health manpower mix as a major factor in the cost of health care delivery regarding these systems. Whereas change is inevitable, it is difficult for state and federal governments in the United States to force change because of the number of special interests involved in campaign financing involving elected government officials. It is nevertheless important for health professionals to be involved in the changes that come about, or change will be made for them. It is essential to renew society, institutions, and individuals in order to prevent decay and obsolescence. If we don't make the future, the future will make us.

  12. Global Health Care Justice, Delivery Doctors and Assisted Reproduction: Taking a Note From Catholic Social Teachings.

    Richie, Cristina

    2015-12-01

    This article will examine the Catholic concept of global justice within a health care framework as it relates to women's needs for delivery doctors in the developing world and women's demands for assisted reproduction in the developed world. I will first discuss justice as a theory, situating it within Catholic social teachings. The Catholic perspective on global justice in health care demands that everyone have access to basic needs before elective treatments are offered to the wealthy. After exploring specific discrepancies in global health care justice, I will point to the need for delivery doctors in the developing world to provide basic assistance to women who hazard many pregnancies as a priority before offering assisted reproduction to women in the developed world. The wide disparities between maternal health in the developing world and elective fertility treatments in the developed world are clearly unjust within Catholic social teachings. I conclude this article by offering policy suggestions for moving closer to health care justice via doctor distribution.

  13. Emerging Technologies of Polymeric Nanoparticles in Cancer Drug Delivery

    Directory of Open Access Journals (Sweden)

    Erik Brewer

    2011-01-01

    Full Text Available Polymeric nanomaterials have the potential to improve upon present chemotherapy delivery methods. They successfully reduce side effects while increasing dosage, increase residence time in the body, offer a sustained and tunable release, and have the ability to deliver multiple drugs in one carrier. However, traditional nanomaterial formulations have not produced highly therapeutic formulations to date due to their passive delivery methods and lack of rapid drug release at their intended site. In this paper, we have focused on a few “smart” technologies that further enhance the benefits of typical nanomaterials. Temperature and pH-responsive drug delivery devices were reviewed as methods for triggering release of encapsulating drugs, while aptamer and ligand conjugation were discussed as methods for targeted and intracellular delivery, with emphases on in vitro and in vivo works for each method.

    Cancer is the third leading cause of death in Iran and its incidence has been increasing in recent years. Patients' quality of life is altered rather enormously due to cancer, which doubles the importance of and the need for providing palliative care in Iran. Although many steps have been taken toward the development and providing of palliative care in Iran, there is still a large gap between the status quo and the desirable state. This study presents the current state of palliative care for cancer patients and discusses the barriers, challenges and outlook of palliative care in Iran. If infrastructural projects that have recently been launched prove successful, proper advancement toward the providing of palliative care services in Iran will then not far on the horizon.

  17. Multidisciplinary care and management selection in prostate cancer.

    Science.gov (United States)

    Aizer, Ayal A; Paly, Jonathan J; Efstathiou, Jason A

    2013-07-01

    The management of prostate cancer is complicated by the multitude of treatment options, the lack of proven superiority of one modality of management, and the presence of physician bias. Care at a multidisciplinary prostate cancer clinic offers patients the relative convenience of consultation with physicians of multiple specialties within the confines of a single visit and appears to serve as a venue in which patients can be counseled regarding the risks and benefits of available therapies in an open and interactive environment. Physician bias may be minimized in such an environment, and patient satisfaction rates are high. Available data suggest that low-risk patients who are seen at a multidisciplinary prostate cancer clinic appear to select active surveillance in greater proportion. However, relatively few studies have investigated the other added value that multidisciplinary clinics provide to the patient or health care system, and therefore, additional studies assessing the impact of multidisciplinary care in the management of patients with prostate cancer are needed.

    Spiraling costs in health care have placed hospitals in a constant state of transition. As a result, nursing practice is now influenced by numerous factors and has remained in a continuous state of flux. Multiple changes within the last 2 decades in nurse/patient ratio and blend of front-line nurses are examples of this transition. To reframe the nursing practice into an economic equation that captures the cost, quality, and service, a paradigm shift in thinking is needed in order to assess work redesign. Nursing productivity must be evaluated in terms of value-added care, a vision that goes beyond direct care activities and includes team collaboration, physician rounding, increased RN-to-aide communication, and patient centeredness; all of which are crucial to the nurse's role and the patient's well-being. The science of appropriating staffing depends on assessment and implementation of systematic changes best illustrated through a "systems theory" framework. A throughput transformation is required to create process changes with input elements (number of front-line nurses) in order to increase time spent in value-added care and to decrease waste activities with an improvement in efficiency, quality, and service. The purpose of this pilot study was two-fold: (a) to gain an understanding of how much time RNs spent in value-added care, and (b) whether increasing the combined level of RNs and unlicensed assistive personnel increased the amount of time spent in value-added care compared to time spent in necessary tasks and waste.

    Capturing patients' perspectives has become an essential part of a quality of care assessment. The patient centeredness questionnaire for PD (PCQ-PD) has been validated in The Netherlands as an instrument to measure patients' experiences. This study aims to assess the level of patient centeredness in North American Parkinson centers and to demonstrate the PCQ-PD's potential as a quality improvement instrument. 20 Parkinson Centers of Excellence participated in a multicenter study. Each center asked 50 consecutive patients to complete the questionnaire. Data analyses included calculating case mix-adjusted scores for overall patient centeredness (scoring range 0-3), six subscales (0-3), and quality improvement (0-9). Each center received a feedback report on their performance. The PCQ-PD was completed by 972 PD patients (median 50 per center, range 37-58). Significant differences between centers were found for all subscales, except for emotional support (p < 0.05). The information subscale (mean 1.62 SD 0.62) and collaboration subscale (mean 2.03 SD 0.58) received the lowest experience ratings. 14 centers (88 %) who returned the evaluation survey claimed that patient experience scores could help to improve the quality of care. Nine centers (56 %) utilized the feedback to change specific elements of their care delivery process. PD patients are under-informed about critical care issues and experience a lack of collaboration between healthcare professionals. Feedback on patients' experiences facilitated Parkinson centers to improve their delivery of care. These findings create a basis for collecting patients' experiences in a repetitive fashion, intertwined with existing quality of care registries.

    I assessed the satisfaction in July-August 2005 of 889 livestock and poultry owners with animal health-care services delivery in peri-urban Ghana and determined factors associated with that satisfaction (and with being the owner of poultry versus of other livestock with or without poultry). Overall, 48% of the respondents were satisfied or very satisfied with service delivery, with only 8% in the very satisfied category. Of the 401 owners of poultry and 488 owners of other livestock, 52% and 45%, respectively, reported being satisfied or very satisfied with veterinary services delivery. I found significant differences between poultry and livestock owners in 11 of 15 indicators of quality of animal health-care services; significantly higher proportions of poultry owners gave positive assessments in nine of the indicators. All but one of the 15 indicators tested was significantly and positively associated with satisfaction among all owners, overall. The indicators are proposed as a checklist for Qualitative Rapid Appraisal of Veterinary Services.

    The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screening and diagnostic services to low-income and underserved women through a network of providers and health care organizations. Although the program serves women 40-64 years old for breast cancer screening and 21-64 years old for cervical cancer screening, the priority populations are women 50-64 years old for breast cancer and women who have never or rarely been screened for cervical cancer. From 1991 through 2011, the NBCCEDP provided screening and diagnostic services to more than 4.3 million women, diagnosing 54,276 breast cancers, 2554 cervical cancers, and 123,563 precancerous cervical lesions. A critical component of providing screening services is to ensure that all women with abnormal screening results receive appropriate and timely diagnostic evaluations. Case management is provided to assist women with overcoming barriers that would delay or prevent follow-up care. Women diagnosed with cancer receive treatment through the states' Breast and Cervical Cancer Treatment Programs (a special waiver for Medicaid) if they are eligible. The NBCCEDP has performance measures that serve as benchmarks to monitor the completeness and timeliness of care. More than 90% of the women receive complete diagnostic care and initiate treatment less than 30 days from the time of their diagnosis. Provision of effective screening and diagnostic services depends on effective program management, networks of providers throughout the community, and the use of evidence-based knowledge, procedures, and technologies.

    Full Text Available Abstract Background Most cancer patients still die in hospital, mainly in medical wards. Many studies in different countries have shown the poor quality of end-of-life care delivery in hospitals. The Program "Liverpool Care Pathway for the dying patient" (LCP, developed in the UK to transfer the hospice model of care into hospitals and other care settings, is a complex intervention to improve the quality of end-of-life care. The results from qualitative and quantitative studies suggest that the LCP Program can improve significantly the quality of end-of-life care delivery in hospitals, but no randomised trial has been conducted till now. Methods and design This is a randomized cluster trial, stratified by regions and matched for assessment period. Pairs of eligible medical wards from different hospitals will be randomized to receive the LCP-I Program or no intervention until the end of the trial. The LCP-I Program will be implemented by a Palliative Care Unit. The assessment of the end-points will be performed for all cancer deaths occurred in the six months after the end of the LCP-I implementation in the experimental wards and, in the same period of time, in the matched control wards. The primary end-point is the overall quality of end-of-life care provided on the ward to dying cancer patients and their families, assessed using the Global Scale of the Italian version of the Toolkit "After-death Bereaved Family Member Interview". Discussion This study can be interpreted as a Phase III trial according to the Medical Research Council Framework. In this study, the effectiveness of a fully defined intervention is assessed by comparing the distribution of the endpoints in the experimental and in the control arm.

    Rising worldwide cancer incidence and resistance to current anti-cancer drugs necessitate the need for new pharmaceutical compounds and drug delivery system. Malfunction of the immune system, particularly in the tumor microenvironment, causes tumor growth and enhances tumor progression. Thus, cancer immunotherapy can be an appropriate approach to provoke the systemic immune system to combat tumor expansion. Texosomes, which are endogenous nanovesicles released by all tumor cells, contribute to cell-cell communication and modify the phenotypic features of recipient cells due to the texosomes’ ability to transport biological components. For this reason, texosome-based delivery system can be a valuable strategy for therapeutic purposes. To improve the pharmaceutical behavior of this system and to facilitate its use in medical applications, biotechnology approaches and mimetic techniques have been utilized. In this review, we present the development history of texosome-based delivery systems and discuss the advantages and disadvantages of each system.

    Carbon based nanomaterials have attracted significant attention over the past decades due to their unique physical properties, versatile functionalization chemistry, and biological compatibility. In this review, we will summarize the current state-of-the-art applications of carbon nanomaterials in cancer imaging and drug delivery/therapy. The carbon nanomaterials will be categorized into fullerenes, nanotubes, nanohorns, nanodiamonds, nanodots and graphene derivatives based on their morphologies. The chemical conjugation/functionalization strategies of each category will be introduced before focusing on their applications in cancer imaging (fluorescence/bioluminescence, magnetic resonance (MR), positron emission tomography (PET), single-photon emission computed tomography (SPECT), photoacoustic, Raman imaging, etc.) and cargo (chemo/gene/therapy) delivery. The advantages and limitations of each category and the potential clinical utilization of these carbon nanomaterials will be discussed. Multifunctional carbon nanoplatforms have the potential to serve as optimal candidates for image-guided delivery vectors for cancer.

    There is wide variation in the proportion of newly diagnosed cancer patients who receive chemotherapy, indicating the need for a benchmark rate of chemotherapy utilisation. This study describes an evidence-based model that estimates the proportion of new cancer patients in whom chemotherapy is indicated at least once (defined as the optimal chemotherapy utilisation rate). The optimal chemotherapy utilisation rate can act as a benchmark for measuring and improving the quality of care. Models of optimal chemotherapy utilisation were constructed for each cancer site based on indications for chemotherapy identified from evidence-based treatment guidelines. Data on the proportion of patient- and tumour-related attributes for which chemotherapy was indicated were obtained, using population-based data where possible. Treatment indications and epidemiological data were merged to calculate the optimal chemotherapy utilisation rate. Monte Carlo simulations and sensitivity analyses were used to assess the effect of controversial chemotherapy indications and variations in epidemiological data on our model. Chemotherapy is indicated at least once in 49.1% (95% confidence interval 48.8-49.6%) of all new cancer patients in Australia. The optimal chemotherapy utilisation rates for individual tumour sites ranged from a low of 13% in thyroid cancers to a high of 94% in myeloma. The optimal chemotherapy utilisation rate can serve as a benchmark for planning chemotherapy services on a population basis. The model can be used to evaluate service delivery by comparing the benchmark rate with patterns of care data. The overall estimate for other countries can be obtained by substituting the relevant distribution of cancer types. It can also be used to predict future chemotherapy workload and can be easily modified to take into account future changes in cancer incidence, presentation stage or chemotherapy indications.

    Ovarian cancer is the most lethal gynaecological cancer. It appears that seemingly ovarian or primary peritoneal carcinomas, in fact, originate from fimbriae. BRCA1/2 mutation carriers are recommended for the removal of ovaries and fimbriae, to reduce the risk of cancer. Treatment of epithelial ovarian cancer is based on the combination of surgery and chemotherapy. The residual tumour volume at the primary operation is the most important predictive factor of survival. The best response at the primary treatment is observed with combination chemotherapy with taxane and platinum. Adding bevacitzumab to first line chemotherapy may improve survival.

    As a result of increasing waiting lists of patients attending National Cancer Institute of Cairo, we are faced to provide high-quality pain care service through our outpatient pain clinic. The program description presented here shows the capacity of a 24 hours/7 days outpatient cancer pain management service to provide rapidly accessible, high-quality care to patients with complex pain and palliative care symptom burdens. In addition, this model avoids inpatient hospital admissions. Pain clinics of cancer are committed to helping patients and families identify and implement the treatments necessary to achieve optimum functional ability and the best possible quality of life. These clinics also help to communicate and work with the family physician, surgeon, and other physicians associated with patient treatment. Cancer pain is complex in its causes, and affects all parts of the body. It involves the tissues, body systems , and the mind. Being multidimensional, it is never adequately addressed with unidimensional treatment. Pain management must extend beyond physical approaches to include the psychological, social, and even spiritual aspects of the patient. Effective integrated treatment fosters self awareness and teaches appropriate and effective self care. With time, complex issues are managed, pain is reduced, and the patient moves toward peak physical and psychological functioning. These goals can be achieved by providing the highest quality pain management services. Patients attending the clinic get treated medically for their physical ailments. Their emotional and psychological problems also need to be attended with an atmosphere of love and care. The mission of the highest quality service is to obtain customer satisfaction with reduction of cost in a multidisciplinary (or better interdisciplinary) approach. This can be reached by proper identification of the customers either internal or external, assessing their needs, and implementing plans for their

    Full Text Available The demand for new healthcare services is growing rapidly. Improving accessibility of the African population to diabetes care seems to be a big challenge in most countries where the number of care centers and medical staff is reduced. Information and communication technologies (ICT have great potential to address some of these challenges faced by several countries in providing accessible, cost-effective, and high-quality health care services. This paper presents the Mobil Diab system which is a telemedical approach proposed for the management of long-term diseases. The system applies modern mobile and web technologies which overcome geographical barriers, and increase access to health care services. The idea of the system is to involve patients in the therapy process and motivate them for an active participation. For validation of the system in African context, a trial was conducted in the Democratic Republic of Congo. 40 Subjects with diabetes divided randomly into control and intervention groups were included in the test. Results show that Mobil Diab is suitable for African countries and presents a number of benefits for the population and public health care system. It improves clinical management and delivery of diabetes care services by enhancing access, quality, motivation, reassurance, efficiency, and cost-effectiveness.

    Prostate cancer is the second most common cancer in men worldwide, accounting for an estimated 1.1 million new cases diagnosed in 2012 (www.globocan.iarc.fr). Currently, there is a lack of specific guidance on supportive care for men with prostate cancer. This article describes a qualitative systematic review and synthesis examining men's experience of and need for supportive care. Seven databases were searched; 20 journal articles were identified and critically appraised. A thematic synthesis was conducted in which descriptive themes were drawn out of the data. These were peer support, support from partner, online support, cancer specialist nurse support, self-care, communication with health professionals, unmet needs (emotional support, information needs, support for treatment-induced side effects of incontinence and erectile dysfunction) and men's suggestions for improved delivery of supportive care. This was followed by the development of overarching analytic themes which were: uncertainty, reframing, and the timing of receiving treatment, information and support. Our results show that the most valued form of support men experienced following diagnosis was one-to-one peer support and support from partners. This review highlights the need for improved access to cancer specialist nurses throughout the care pathway, individually tailored supportive care and psychosexual support for treatment side effects.

    In 2012, 27 organizations will initiate participation in the Medicare Shared Savings Program as Accountable Care Organizations. This level of participation reflects the response of Centers for Medicare and Medicaid Services to criticism that the program as outlined in the proposed rule was overly burdensome, prescriptive, and too risky. Centers for Medicare and Medicaid Service made significant changes in the final rule, making the Accountable Care Organization program more attractive to these participants. However, none of these changes addressed the serious concerns raised by subspecialty societies-including the American Society of Nephrology-regarding care of patients with multiple chronic comorbidities and complex and end stage conditions. Virtually all of these concerns remain unaddressed, and consequently, Accountable Care Organizations will require guidance and partnership from the nephrology community to ensure that these patients are identified and receive the individualized care that they require. Although the final rule fell short of addressing the needs of patients with kidney disease, the Centers for Medicare and Medicaid Innovation presents an opportunity to test the potentially beneficial concepts of the Accountable Care Organization program within this patient population. The American Society of Nephrology Accountable Care Organization Task Force developed a set of principles that must be reflected in a possible pilot program or demonstration project of an integrated nephrology care delivery model. These principles include preserving a leadership role for nephrologists, encompassing care for patients with later-stage CKD and kidney transplants as well as ESRD, enabling the participation of a diversity of dialysis provider sizes and types, facilitating research, and establishing monitoring systems to identify and address preferential patient selection or changes in outcomes.

Maria, Province of Laguna during the first semester of school year 2012-2013. Descriptive research was used in this study. Among the key findings were that Day Care Workers with respect to interactional relationship accomplished the functions with outstanding adequacy such as constantly giving feedback and praises on the performance of children, along with workers and parents coordination and cooperation, with verbal interpretation of Always Observe. In terms of instructional quality both group of respondents perceived that day care workers in-charge had adequate abilities and competencies concerning their education and trainings in connection with teaching small children with verbal interpretation of Always Observe. The parents had confidence to the day care workers in-charge of their children aside from regularly consulting the day care workers about their children’s progress with verbal interpretation of Always Observe. There were only 871 households who availed of the services of day care centers in which 27 workers were employed and each of them assigned to handle an average of 33 children. Notable along with other findings was the day care workers and parents had the same perception as to the extent of services provided by the Day Care Center with respect to interactional relationship, instructional quality and parental participation. Subsequently the study ensued with these five factual remarks: Children’s interactions with parents in the centers were the direct mechanisms through which children learn. The educational qualification and the capability of the day care workers to handle small children were the primary essentials in children’s learning. Parents’ participation in the day care centers premises brought harmonious relationship between the Day Care Workers and children as well. The capacity of day care worker

    Introduction: Healthcare leaders need operational strategies that support organizational learning for continued improvement and value generation. The learning health system (LHS) model may provide leaders with such strategies; however, little is known about leaders’ perspectives on the value and application of system-wide operationalization of the LHS model. The objective of this project was to solicit and analyze senior health system leaders’ perspectives on the LHS and learning activities in an integrated delivery system. Methods: A series of interviews were conducted with 41 system leaders from a broad range of clinical and administrative areas across an integrated delivery system. Leaders’ responses were categorized into themes. Findings: Ten major themes emerged from our conversations with leaders. While leaders generally expressed support for the concept of the LHS and enhanced system-wide learning, their concerns and suggestions for operationalization where strongly aligned with their functional area and strategic goals. Discussion: Our findings suggests that leaders tend to adopt a very pragmatic approach to learning. Leaders expressed a dichotomy between the operational imperative to execute operational objectives efficiently and the need for rigorous evaluation. Alignment of learning activities with system-wide strategic and operational priorities is important to gain leadership support and resources. Practical approaches to addressing opportunities and challenges identified in the themes are discussed. Conclusion: Continuous learning is an ongoing, multi-disciplinary function of a health care delivery system. Findings from this and other research may be used to inform and prioritize system-wide learning objectives and strategies which support reliable, high value care delivery. PMID:27683668

    Full Text Available Prevention plays a central role in early detection of cervical cancer. Common Sense Model proposes that the nature and organization of illness representations can guide actions related to health and how self-care is exercised. The aim of this study was to describe and compare illness perception, knowledge and self-care in women with and without cancer precursor lesions. Participants were 92 women (aged 18-59 from primary care unity divided into two groups: women with and without premalignant lesion. Measures for illness perception, knowledge and self-care were used. There was no statistically significant difference (t test e chi-square test between groups in the variables analyzed. Despite the risk for cervical cancer, women with precursor lesions do not adjust their illness perceptions, knowledge and self-care to the situation. These data show the need to warn women against the cervical cancer risks, because their distorted perceptions and lack of knowledge about the disease may hamper the screening and control of cervical cancer.

    Northouse, L L; Wortman, C B

    1990-02-01

    This paper provides a theoretical analysis of four models of helping and coping as they relate to cancer care. The four conceptual models focus on the issue of whether or not patients should be viewed as responsible for the cause or the treatment of their cancer. The moral model, characterized by the holistic health movement, holds patients responsible for both causing and resolving health problems. The compensatory model, exemplified by cancer education programs, attributes low responsibility to patients for causing health problems but high responsibility for resolving them. The medical model views patients as neither responsible for causing nor for resolving health problems. The enlightenment model, typified by the healing movement, holds people responsible for causing their health problems, but not for resolving them. An attempt is made to examine existing programs in cancer care in light of these models. The present analysis addresses the following questions. Why is each of these models appealing? Why are they sometimes embraced by patients or health care providers? What are the benefits and disadvantages of using each of these models with cancer patients? What happens when the health care provider and patient hold different models regarding the patient's responsibility or participation in the cause of the disease or its treatment? Further research is needed to determine the conditions under which a particular model results in better health outcomes for patients, and to assess how factors such as extent of disease or type of cancer influence the patient's choice of a model.

    Organisational culture has been shown to impact on resident outcomes in residential aged care (RAC). This is particularly important given the growing number of residents with high palliative care needs. The study described herein (conducted from January 2013 to March 2014) examined survey results from a convenience sample of 46 managers, alongside interviews with a purposively selected sample of 23 bereaved family members in order to explore the perceptions of organisational culture within New Zealand RAC facilities in one large urban District Health Board. Results of the Organisational Culture Assessment Instrument (OCAI) completed by managers indicated a preference for a 'Clan' and the structured 'Hierarchy' culture. Bereaved family interviews emphasised both positive and negative aspects of communication, leadership and teamwork, and relationship with residents. Study results from both managers' OCAI survey scores and next of kin interviews indicate that while the RAC facilities are culturally oriented towards providing quality care for residents, they may face barriers to adopting organisational processes supportive of this goal.

    Full Text Available Abstract Background Trained birth attendants at delivery are important for preventing both maternal and newborn deaths. West Java is one of the provinces on Java Island, Indonesia, where many women still deliver at home and without the assistance of trained birth attendants. This study aims to explore the perspectives of community members and health workers about the use of delivery care services in six villages of West Java Province. Methods A qualitative study using focus group discussions (FGDs and in-depth interviews was conducted in six villages of three districts in West Java Province from March to July 2009. Twenty FGDs and 165 in-depth interviews were conducted involving a total of 295 participants representing mothers, fathers, health care providers, traditional birth attendants and community leaders. The FGD and in-depth interview guidelines included reasons for using a trained or a traditional birth attendant and reasons for having a home or an institutional delivery. Results The use of traditional birth attendants and home delivery were preferable for some community members despite the availability of the village midwife in the village. Physical distance and financial limitations were two major constraints that prevented community members from accessing and using trained attendants and institutional deliveries. A number of respondents reported that trained delivery attendants or an institutional delivery were only aimed at women who experienced obstetric complications. The limited availability of health care providers was reported by residents in remote areas. In these settings the village midwife, who was sometimes the only health care provider, frequently travelled out of the village. The community perceived the role of both village midwives and traditional birth attendants as essential for providing maternal and health care services. Conclusions A comprehensive strategy to increase the availability, accessibility, and

    Answer questions and earn CME/CNE The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.

    Breast cancer is the most frequently occurring cancer among women throughout the world. Natural compounds such as curcumin hold promise to treat a variety of cancers including breast cancer. However, curcumin's therapeutic application is limited, due to its rapid degradation and poor aqueous solubility. On the other hand, previous studies have stated that drug delivery using nanoparticles might improve the therapeutic response to anticancer drugs. Poly(N-isopropylacrylamide-co-methacrylic acid) (PNIPAAm-MAA) is one of the hydrogel copolymers utilized in the drug delivery system for cancer therapy. The aim of this study was to examine the cytotoxic potential of curcumin encapsulated within the NIPAAm-MAA nanoparticle, on the MCF-7 breast cancer cell line. In this work, polymeric nanoparticles were synthesized through the free radical mechanism, and curcumin was encapsulated into NIPAAm-MAA nanoparticles. Then, the cytotoxic effect of curcumin-loaded NIPAAm-MAA on the MCF-7 breast cancer cell line was measured by MTT assays. The evaluation of the results showed that curcumin-loaded NIPAAm-MAA has more cytotoxic effect on the MCF-7 cell line and efficiently inhibited the growth of the breast cancer cell population, compared with free curcumin. In conclusion, this study indicates that curcumin-loaded NIPAAm-MAA suppresses the growth of the MCF-7 cell line. Overall, it is concluded that encapsulating curcumin into the NIPAAm-MAA copolymer could open up new avenues for breast cancer treatment.

    Wirelessly guided magnetic nanomachines are promising vectors for targeted drug delivery, which have the potential to minimize the interaction between anticancer agents and healthy tissues. In this work, we propose a smart multifunctional drug delivery nanomachine for targeted drug delivery that incorporates a stimuli-responsive building block. The nanomachine consists of a magnetic nickel (Ni) nanotube that contains a pH-responsive chitosan hydrogel in its inner cavity. The chitosan inside the nanotube serves as a matrix that can selectively release drugs in acidic environments, such as the extracellular space of most tumors. Approximately a 2.5 times higher drug release from Ni nanotubes at pH = 6 is achieved compared to that at pH = 7.4. The outside of the Ni tube is coated with gold. A fluorescein isothiocyanate (FITC) labeled thiol-ssDNA, a biological marker, was conjugated on its surface by thiol-gold click chemistry, which enables traceability. The Ni nanotube allows the propulsion of the device by means of external magnetic fields. As the proposed nanoarchitecture integrates different functional building blocks, our drug delivery nanoplatform can be employed for carrying molecular drug conjugates and for performing targeted combinatorial therapies, which can provide an alternative and supplementary solution to current drug delivery technologies.Wirelessly guided magnetic nanomachines are promising vectors for targeted drug delivery, which have the potential to minimize the interaction between anticancer agents and healthy tissues.

    Cervical cancer is uterine cervix carcinoma, the second deadly cancer and has a high incidence and mortality rate. In the developing world conventional treatment strategies such as surgical intervention and chemoradiotherapy are less widely available. Currently cancer research focuses on improving treatment of cervical cancer using various therapies such as gene therapy, recombinant protein therapy, photodynamic therapy, photothermal therapy and delivery of chemotherapeutic agents using nanoparticles, hydrogel and liposomal based delivery systems and also localized delivery systems which exist in a variety of forms such as intravaginal rings, intravaginal patches, intravaginal films, etc. in order to improve the drug delivery in a controlled manner to the diseased site thereby reducing systemic side effects. The present review encloses existing diverse delivery systems and approaches intended for treatment of cervical cancer.

    2011-01-01

    Full Text Available Abstract Among all cancer treatment options, chemotherapy continues to play a major role in killing free cancer cells and removing undetectable tumor micro-focuses. Although chemotherapies are successful in some cases, systemic toxicity may develop at the same time due to lack of selectivity of the drugs for cancer tissues and cells, which often leads to the failure of chemotherapies. Obviously, the therapeutic effects will be revolutionarily improved if human can deliver the anticancer drugs with high selectivity to cancer cells or cancer tissues. This selective delivery of the drugs has been called target treatment. To realize target treatment, the first step of the strategies is to build up effective target drug delivery systems. Generally speaking, such a system is often made up of the carriers and drugs, of which the carriers play the roles of target delivery. An ideal carrier for target drug delivery systems should have three pre-requisites for their functions: (1 they themselves have target effects; (2 they have sufficiently strong adsorptive effects for anticancer drugs to ensure they can transport the drugs to the effect-relevant sites; and (3 they can release the drugs from them in the effect-relevant sites, and only in this way can the treatment effects develop. The transporting capabilities of carbon nanotubes combined with appropriate surface modifications and their unique physicochemical properties show great promise to meet the three pre-requisites. Here, we review the progress in the study on the application of carbon nanotubes as target carriers in drug delivery systems for cancer therapies.

  20. Pectin matrix as oral drug delivery vehicle for colon cancer treatment.

    2011-03-01

    Colon cancer is the fourth most common cancer globally with 639,000 deaths reported annually. Typical chemotherapy is provided by injection route to reduce tumor growth and metastasis. Recent research investigates the oral delivery profiles of chemotherapeutic agents. In comparison to injection, oral administration of drugs in the form of a colon-specific delivery system is expected to increase drug bioavailability at target site, reduce drug dose and systemic adverse effects. Pectin is suitable for use as colon-specific drug delivery vehicle as it is selectively digested by colonic microflora to release drug with minimal degradation in upper gastrointestinal tract. The present review examines the physicochemical attributes of formulation needed to retard drug release of pectin matrix prior to its arrival at colon, and evaluate the therapeutic value of pectin matrix in association with colon cancer. The review suggests that multi-particulate calcium pectinate matrix is an ideal carrier to orally deliver drugs for site-specific treatment of colon cancer as (1) crosslinking of pectin by calcium ions in a matrix negates drug release in upper gastrointestinal tract, (2) multi-particulate carrier has a slower transit and a higher contact time for drug action in colon than single-unit dosage form, and (3) both pectin and calcium have an indication to reduce the severity of colon cancer from the implication of diet and molecular biology studies. Pectin matrix demonstrates dual advantages as drug carrier and therapeutic for use in treatment of colon cancer.

    Local tumor recurrence after cervical cancer surgery remains a clinical problem. Vaginal delivery of thermosensitive hydrogel may be suited to reduce tumor relapse rate with more efficacy and safety. A pilot study was carried out to evaluate the efficacy of carboplatin-loaded poloxamer hydrogel to prevent local recurrence of cervical cancer after surgery. In vivo vaginal retention evaluation of 27% poloxamer hydrogel in mice was proven to be a suitable vaginal drug delivery formulation due to its low gelation temperature. A mimic orthotopic cervical/vaginal cancer recurrence model after surgery was established by injecting murine cervical cancer cell line U14 into the vaginal submucosa to simulate the residual tumor cells infiltrated in the surgical site, followed by drug administration 24 h later to interfere with the formation/recurrence of the tumor. By infusing fluorescein sodium-loaded hydrogel into the vagina of mice, a maximized accumulation of fluorescein sodium (Flu) in the vagina was achieved and few signals were observed in other organs. When used in the prevention of the cervical cancer formation/recurrence in mice, the carboplatin-loaded poloxamer hydrogel exhibited great efficacy and systemic safety. In conclusion, thermosensitive hydrogel presents a simple, practical approach for the local drug delivery via vagina against cervical cancer recurrence.

    In response to increased public interest in cancer prevention and rapidly escalating health care costs, the National Cancer Institute supported the development of cancer prevention courses for health professionals. A multidisciplinary group of physicians, behavioral scientists, and educators developed, field-tested, revised, and evaluated a 12-module, 24-classroom-hour clinical preventive oncology course for primary care physicians. A rationale for education in cancer prevention is presented, the new clinical discipline of preventive oncology is defined, and contributory disciplines are identified. A curriculum based upon detailed learning objectives is described, short-term evaluation data are presented, and a methodology for incorporating a didactic course into a residency program is suggested. The positive reception given to this course by residents warrants optimism concerning application of a biopsychosocial or self-regulative model rather than the traditional biomedical one to clinical medicine and its teaching.

    One of the problems in health care in developing countries is the bad accessibility of medicine in pharmacies for patients. Since this is mainly due to a lack of organization and information, it should be possible to improve the situation by introducing information and communication technology. However, for several reasons, standard solutions are not applicable here. In this paper, we describe a case study in Benin, a West African developing country. We identify the problem and the existing obstacles for applying standard ECommerce solutions. We develop an adapted system approach and describe a practical test which has shown that the approach has the potential of actually improving the pharmaceutical care delivery. Finally, we consider the security aspects of the system and propose an organizational solution for some specific security problems.

    The diagnosis and subsequent treatment of prostate cancer is followed by a range of significant disease specific and iatrogenic sequelae. However, the supportive care needs of men with prostate cancer are not well described in the literature. The present study assesses the supportive care needs of men with prostate cancer who are members of prostate cancer self-help groups in Queensland, Australia. In all, 206 men aged between 48 and 85 years (mean=68) completed the Supportive Care Needs Survey (SCNS) (62% response). The SCNS is a validated measure assessing perceived need in the domains of psychological needs, health system and information needs, physical and daily living needs, patient care and support, and sexuality. Items assessing need for access to services and resources were also included. One third of the sample reported a moderate to high need for help for multiple items in the sexuality, psychological and health system and information domains. Younger men reported greater need in the sexuality domain; living in major urban centres was predictive of greater psychological need; being closer to the time of diagnosis was related to greater need for help in the physical and daily living domain; having prostate cancer that is not in remission, having received radiation therapy, and lower levels of education were predictive of greater need for help in patient care and support. Of the total sample, 55% of men had used alternative cancer treatments in the past 12 months, with younger and more educated men more likely to use alternative therapies. Interventions in sexuality, psychological concerns and informational support are priorities for men with prostate cancer.

    Full Text Available Abstract Background While physicians are key to primary preventive care, their delivery rate is sub-optimal. Assessment of physician beliefs is integral to understanding current behavior and the conceptualization of strategies to increase delivery. Methods A focus group with regional primary care physician (PCP Opinion Leaders was conducted as a formative step towards regional assessment of attitudes and barriers regarding preventive care delivery in primary care. Following the PRECEDE-PROCEED model, the focus group aim was to identify conceptual themes that characterize PCP beliefs and practices regarding preventive care. Seven male and five female PCPs (family medicine, internal medicine participated in the audiotaped discussion of their perceptions and behaviors in delivery of primary preventive care. The transcribed audiotape was qualitatively analyzed using grounded theory methodology. Results The PCPs' own perceived role in daily practice was a significant barrier to primary preventive care. The prevailing PCP model was the "one-stop-shop" physician who could provide anything from primary to tertiary care, but whose provision was dominated by the delivery of immediate diagnoses and treatments, namely secondary care. Conclusions The secondary-tertiary prevention PCP model sustained the expectation of immediacy of corrective action, cure, and satisfaction sought by patients and physicians alike, and, thereby, de-prioritized primary prevention in practice. Multiple barriers beyond the immediate control of PCP must be surmounted for the full integration of primary prevention in primary care practice. However, independent of other barriers, physician cognitive value of primary prevention in practice, a base mediator of physician behavior, will need to be increased to frame the likelihood of such integration.

    Gestational breast cancer (GBC) presents many challenges for women and the clinicians who care for them. The aim of this study was to explore the health care experiences of women diagnosed with GBC to inform and improve clinical care of women in this predicament. Semi-structured interviews were conducted with 17 women who had been diagnosed with GBC in the previous 5 years. The overarching themes for perceived quality of care were "communication" and "comprehensive care." "Communication" had two sub themes: "interdisciplinary communication" (the way health professionals from different disciplines communicated with each other about the management of the woman's care) and "patient communication" (how they communicated this to the woman). The "comprehensive care" theme incorporated three sub themes: "the spirit" (psychological care); "the mind" (information provision); and "the body" (management of treatment side effects). Women's own accounts of positive and negative experiences of GBC care provide unique and specific insights which improve understanding of their concerns and needs. The findings can inform advances in quality and efficacy of clinical care; offer guidance for obstetricians, oncologists and allied health professionals about the needs of women diagnosed with GBC and how care can be optimised; and inform the development of resources to assist women and their families.

  8. Towards a new moral paradigm in health care delivery: accounting for individuals.

    2010-01-01

    For years, commentators have debated how to most appropriately allocate scarce medical resources over large populations. In this paper, I abstract the major rationing schema into three general approaches: rationing by price, quantity, and prioritization. Each has both normative appeal and considerable weakness. After exploring them, I present what some commentators have termed the "moral paradigm" as an alternative to broader philosophies designed to encapsulate the universe of options available to allocators (often termed the market, professional, and political paradigms). While not itself an abstraction of any specific viable rationing scheme, it provides a strong basis for the development of a new scheme that offers considerable moral and political appeal often absent from traditionally employed rationing schema. As I explain, the moral paradigm, in its strong, absolute, and uncompromising version, is economically untenable. This paper articulates a modified version of the moral paradigm that is pluralist in nature rather than absolute. It appeals to the moral, emotional, and irrational sensibilities of each individual person. The moral paradigm, so articulated, can complement any health care delivery system that policy-makers adopt. It functions by granting individuals the ability to appeal to an administrative adjudicatory board designated for this purpose. The adjudicatory board would have the expertise and power to act in response to the complaints of individual aggrieved patients, including those complaints that stem from the moral, religious, ethical, emotional, irrational, or other subjective positions of the patient, and would have plenary power to affirm the denial of access to medical care or to mandate the provision of such care. The board must be designed to facilitate its intended function while creating structural limitations on abuse of power and other excess. I make some specific suggestions on matters of structure and function in the hope of

    Full Text Available Breast cancer survivors are at risk of developing a second primary cancer. Colorectal cancer (CRC is one of the leading second primary cancers, and it is often preventable. We developed a multi-component educational tool to inform and encourage women breast cancer survivors to engage in CRC screening. To assess the strengths and weakness of the tool and to improve the relevancy to the target audience, we convened four focus groups of women breast cancer survivors in Missouri. We also assessed the potential impact of the tool on the knowledge, attitudes, and beliefs regarding CRC and collected information on the barriers to CRC screening through pre- and post-focus groups’ questionnaires. A total of 43 women breast cancer survivors participated and provided very valuable suggestions on design and content to update the tool. Through the process and comparing pre- and post-focus group assessments, a significantly higher proportion of breast cancer survivors strongly agreed or agreed that CRC is preventable (78.6% vs. 96.9%, p = 0.02 and became aware that they were at a slightly increased risk for CRC (18.6% vs. 51.7%, p = 0.003. The most cited barrier was the complexity of preparation for colonoscopy.

    Exosomes denote a class of secreted nanoparticles defined by size, surface protein and lipid composition, and the ability to carry RNA and proteins. They are important mediators of intercellular communication and regulators of the cellular niche, and their altered characteristics in many diseases, such as cancer, suggest them to be important both for diagnostic and therapeutic purposes, prompting the idea of using exosomes as drug delivery vehicles, especially for gene therapy. This review covers the current status of evidence presented in the field of exosome-based drug delivery systems. Components for successful exosome-based drug delivery, such as choice of donor cell, therapeutic cargo, use of targeting peptide, loading method and administration route are highlighted and discussed with a general focus pertaining to the results obtained in models of different cancer types. In addition, completed and on-going clinical trials are described, evaluating exosome-based therapies for the treatment of different cancer types. Due to their endogenous origin, exosome-based drug delivery systems may have advantages in the treatment of cancer, but their design needs further refinement to justify their usage on the clinical scale.

    Efficient delivery of small interfering RNAs (siRNAs) to the targeted cells has remained a significant challenge in clinical applications. In the present study, we developed a novel aptamer-siRNA chimera delivery system mediated by cationic Au-Fe3O4 nanoparticles (NPs). The chimera constructed by VEGF RNA aptamer and Notch3 siRNA was bonded with heterogeneous Au-Fe3O4 nanoparticles by electrostatic interaction. The obtained complex exhibited much higher silencing efficiency against Notch3 gene compared with chimera alone and lipofectamine-siRNA complex, and improved the antitumor effects of the loaded chimera. Moreover, the efficient delivery of the chimera by Au-Fe3O4 NPs could reverse multi-drug resistance (MDR) of ovarian cancer cells against the chemotherapeutic drug cisplatin, indicating its potential capability for future targeted cancer therapy while overcoming MDR.

    According to the most recent statistics from the National Center for Education Statistics, disparities in enrollment in undergraduate and graduate education are significant and not improving commensurate with the national population. Similarly, only 12% of graduating medical students and 13% of graduating physician assistant students are from underrepresented racial and ethnic groups. Established in 2012 to promote health care transformation at the organization and system levels, the School for the Science of Health Care Delivery is aligned with the university and college missions to create innovative, interdisciplinary curricula that meet the needs of our diverse patient and community populations. Three-year enrollment trends in the program exceed most national benchmarks, particularly among students who identify as Hispanic and American Indian/Alaska Native. The Science of Health Care Delivery program provides students a seamless learning experience that prepares them to be solutions-oriented leaders proficient in the business of health care, change management, innovation, and data-driven decision making. Defined as the study and design of systems, processes, leadership and management used to optimize health care delivery and health for all, the Science of Health Care Delivery will prepare the next generation of creative, diverse, pioneering leaders in health care.

    Background. Pharmacopuncture, injection to acupoints with pharmacological medication or herbal medicine, is a new acupuncture therapy widely available in Korea and China for cancer-related symptoms. However, the evidence is yet to be clear. Objective. To determine pharmacopuncture's effectiveness on cancer-related symptoms. Methods. Eleven databases were searched for randomized controlled trials of pharmacopuncture in cancer patients. The Cochrane risk of bias (ROB) assessment tool was used for quality assessment. Results. Twenty-two studies involving 2,459 patients were included. Five trials of chemotherapy-induced nausea and vomiting (CINV) underwent meta-analysis. Pharmacopuncture significantly relieved severity of CINV compared with control group (3 trials, risk ratio (RR) 1.28, 95% confidence interval (CI) = 1.14-1.44). The frequency of CINV was also significantly reduced with pharmacopuncture (2 trials, RR 2.47, 95% CI = 2.12-2.89). Seventeen trials studied various symptoms, and in most studies, pharmacopuncture significantly relieved pain, ileus, hiccup, fever, and gastrointestinal symptoms and improved quality of life in various cancer patients. ROB was generally high. Conclusion. It may be suggested with caution that pharmacopuncture may help various symptom relief in cancer patients, but it is hard to draw a firm conclusion due to clinical heterogeneity and high ROB of the included studies, hence warranting further investigation.

    Full Text Available With the advent of molecular targeted therapies and the development of high-throughput biotechnologies, it has become evident that progress in cancer research is largely due to the creation of multidisciplinary teams able to plan clinical trials supported by appropriate molecular hypotheses. These efforts have culminated in the identification and validation of biomarkers predictive of response, as well as in the generation of more accurate prognostic tools. The identification of cancer stem cells has provided further insights into mechanisms of cancer, and many studies have tried to translate this biological notion into prognostic and predictive information. In this regard, new agents targeting key stemness-related pathways have entered the clinical development, and preliminary data suggested an encouraging antitumor activity.

    Full Text Available Background: Routine eye and vision assessments are vital for the detection and subsequent management of vision loss, which is particularly important for Aboriginal and Torres Strait Islander people, who face higher rates of vision loss than other Australians. In order to guide improvements, this paper will describe patterns, variations and gaps in these eye and vision assessments for Aboriginal and Torres Strait Islander people. Methods: Clinical audits from 124 primary health care centres (sample size 15,175 from five Australian States and Territories were conducted during 2005-2012. Main outcome measure was adherence to current guidelines for delivery of eye and vision assessments to adults with diabetes, those without a diagnosed major chronic disease and children attending primary health care centres. Results: Overall delivery of recommended eye and vision assessments varied widely between health centres. Of the adults with diabetes, 45% had a visual acuity assessment recorded within the previous 12 months (health centre range 0-88%, and 33% had a retinal examination recorded (health centre range 0-73%. Of the adults with no diagnosed major chronic disease, 31% had a visual acuity assessment recorded within the previous two years (health centre range 0-30%, and 13% had received an examination for trichiasis (health centre range 0-40%. In children, 49% had a record of a vision assessment (health centre range 0-97%, and 25% had a record of an examination for trachoma within the previous 12 months (health centre range 0-63%. Conclusions: There was considerable range, and variation in the recorded delivery of scheduled eye and vision assessments across health centres. Sharing the successful strategies of the better-performing health centres to support focused improvements in key areas of need may increase overall rates of eye examinations – important for the timely detection, referral and treatment of eye conditions affecting Aboriginal and

    2011-05-15

    Abstract Background Many western countries have policies of dispersal and direct provision accommodation (state-funded accommodation in an institutional centre) for asylum seekers. Most research focuses on its effect on the asylum seeking population. Little is known about the impact of direct provision accommodation on organisation and delivery of local primary care and social care services in the community. The aim of this research is to explore this issue. Methods In 2005 a direct provision accommodation centre was opened in a rural area in Ireland. A retrospective qualitative case study was designed comprising in-depth interviews with 37 relevant stakeholders. Thematic analysis following the principles of framework analysis was applied. Results There was lack of advance notification to primary care and social care professionals and the community about the new accommodation centre. This caused anxiety and stress among relevant stakeholders. There was insufficient time to plan and prepare appropriate primary care and social care for the residents, causing a significant strain on service delivery. There was lack of clarity about how primary care and social care needs of the incoming residents were to be addressed. Interdisciplinary support systems developed informally between healthcare professionals. This ensured that residents of the accommodation centre were appropriately cared for. Conclusions Direct provision accommodation impacts on the organisation and delivery of local primary care and social care services. There needs to be sufficient advance notification and inter-agency, inter-professional dialogue to manage this. Primary care and social care professionals working with asylum seekers should have access to training to enhance their skills for working in cross-cultural consultations.

    Transdermal vaccination with cancer antigens is expected to become a useful anti-cancer therapy. However, it is difficult to accumulate enough antigen in the epidermis for effective exposure to Langerhans cells because of diffusion into the skin and muscle. Carriers, such as liposomes and nanoparticles, may be useful for the prevention of antigen diffusion. Iontophoresis, via application of a small electric current, is a noninvasive and efficient technology for transdermal drug delivery. Previously, we succeeded in the iontophoretic transdermal delivery of liposomes encapsulating insulin, and accumulation of polymer-based nanoparticle nanogels in the stratum corneum of the skin. Therefore, in the present study, we examined the use of iontophoresis with cancer antigen gp-100 peptide KVPRNQDWL-loaded nanogels for anti-cancer vaccination. Iontophoresis resulted in the accumulation of gp-100 peptide and nanogels in the epidermis, and subsequent increase in the number of Langerhans cells in the epidermis. Moreover, tumor growth was significantly suppressed by iontophoresis of the antigen peptide-loaded nanogels. Thus, iontophoresis of the antigen peptide-loaded nanogels may serve as an effective transdermal delivery system for anti-cancer vaccination.

    Approximately 15% of expected births worldwide will result in life-threatening complications during pregnancy, delivery, or the postpartum period. Providers skilled in emergency obstetric and newborn care (EmONC) services are essential, particularly in countries with a high burden of maternal and newborn mortality. Jhpiego and its consortia partners have implemented three global programs to build provider capacity to provide comprehensive EmONC services to women and newborns in these resource-poor settings. Providers have been educated to deliver high-impact maternal and newborn health interventions, such as prevention and treatment of postpartum hemorrhage and pre-eclampsia/eclampsia and management of birth asphyxia, within the broader context of quality health services. This article describes Jhpiego's programming efforts within the framework of the basic and expanded signal functions that serve as indicators of high-quality basic and emergency care services. Lessons learned include the importance of health facility strengthening, competency-based provider education, global leadership, and strong government ownership and coordination as essential precursors to scale-up of high impact evidence-based maternal and newborn interventions in low-resource settings.

    Full Text Available Being a great threat to human health, with no permanent cure yet, better treatment and further research in cancer are inevitable. Nanoparticle drug delivery systems (NDDSs, especially pH-sensitive NDDSs, such as lipid-based, polymeric, and mesoporous silica nanoparticles have played a significant role in cancer treatments. Further, three-dimensional (3D cell cultures models, which include tumor spheroid models, microfluidic systems, and matrix/scaffolds-based 3D tumor, better mimic the tumor microenvironment than the conventional two-dimensional cultures, making it possible to better understand the disease while serving as a useful in vitro model for future research. The present review mainly focuses on such 3D cell cultures and drug delivery systems that are applied in cancer research and treatments.

    Owing to its aggressiveness and the lack of effective therapies, pancreatic ductal adenocarcinoma has a dismal prognosis. New strategies to improve treatment and survival are therefore urgently required. Numerous fucosylated antigens in sera serve as tumor markers for cancer detection and evaluation of treatment efficacy. Increased expression of fucosyltransferases has also been reported for pancreatic cancer. These enzymes accelerate malignant transformation through fucosylation of sialylated precursors, suggesting a crucial requirement for fucose by pancreatic cancer cells. With this in mind, we developed fucose-bound nanoparticles as vehicles for delivery of anticancer drugs specifically to cancer cells. L-fucose-bound liposomes containing Cy5.5 or Cisplatin were effectively delivered into CA19-9 expressing pancreatic cancer cells. Excess L-fucose decreased the efficiency of Cy5.5 introduction by L-fucose-bound liposomes, suggesting L-fucose-receptor-mediated delivery. Intravenously injected L-fucose-bound liposomes carrying Cisplatin were successfully delivered to pancreatic cancer cells, mediating efficient tumor growth inhibition as well as prolonging survival in mouse xenograft models. This modality represents a new strategy for pancreatic cancer cell-targeting therapy.

This study explored patient’s self-rated health and patient satisfaction with health care ­providers, and examined whether health care providers are a barrier to patient care. The sample consisted of 2000 men aged 55 years and older in the parish of St Catherine, Jamaica. A 132-item ­questionnaire was used to collect the data. Descriptive statistics was used to provide information about their satisfaction with the health care system. Seventy-four percent of the sample indicated good self-rated health status (excellent, 19.0%. Forty-seven percent of the sample had sought advice from a health care provider in the last 12 months; 14.1% understood the advice of the clinician, community health aide (19.9%, pharmacist (15.4%, nurse (2.1% and nurse aide (4.6%. The respondents indicated that community health aides contributed more to improving their health (43.4% when compared with nurses (34.8%, clinicians (17.5%, and herbalists (3.7%. Furthermore, 31.7% indicated that their medical doctors were hospitable and 4.2% were knowledgeable. Negative self-rated health, perceived lack of knowledge among doctors, lack of understanding of advice from health care providers, are just some of the factors associated with dissatisfaction of patients with chronic conditions. These findings provide a framework and foundation from which further studies on effective intervention aimed at

    Most poor countries have a large and growing private medical sector. Evidence suggests that a large proportion of tuberculosis patients in many high TB- burden countries first approach a private health care provider. Further, private providers manage a significant proportion of tuberculosis cases. Surprisingly though, there is virtually no published evidence on linking private providers to tuberculosis programmes. As a part of global efforts to control tuberculosis through effective DOTS implementation, the World Health Organization has recently begun addressing the issue of private providers in TB control through an evolving global strategy. As a first step, a global assessment of private providers' participation in tuberculosis programmes was undertaken. The findings of the assessment were discussed and debated in a consultation involving private practitioners, TB programme managers and policy makers. Their recommendations have contributed to the evolving global strategy called Public-Private Mix for DOTS implementation (PPM DOTS). This paper presents the guiding principles of PPM DOTS and major elements of the global strategy. These include: informed advocacy; setting-up "learning projects"; scaling-up successful projects and formulation of regional, national and local strategies; developing practical tools to facilitate PPM DOTS and pursuing an operational research agenda to help better design and shape PPM DOTS strategies. Encouraging results from some ongoing project sites are discussed. The paper concludes that concerted global efforts and local input are required for a sustained period to help achieve productive engagement of private practitioners in DOTS implementation. Such efforts have to be targeted as much towards national tuberculosis programmes as towards private providers and their associations. Continued apathy in this area could not only potentially delay achieving global targets for TB control but also undo, in the long run, the hard

    The Tamil Nadu model of public health is renowned for its success in providing quality health services at an affordable cost especially to the rural people. Tamil Nadu is the only state with a distinctive public health cadre in the district level and also the first state to enact a Public Health Act in 1939. Tamil Nadu has gained significant ground in the various aspects of health in the last few decades largely because of the significant reforms in its health sector which dates back to 1980s which saw rigorous expansion of rural health infrastructure in the state besides deployment of thousands of multipurpose health workers as village health nurses in rural areas. Effective implementation of Universal Immunization Programme, formation of Tamil Nadu Medical Services Corporation for regulating the drug procurement and promoting generic drugs, early incorporation of indigenous system of medicine into health care service, formulation of a health policy in 2003 by the state with special emphasis on low-income, disadvantaged communities alongside efficient implementation of The Tamil Nadu Health Systems Project (TNHSP) are the major factors which contributed for the success of the state. The importance of good political commitment and leadership in the health gains of the state warrants special mention. Moreover, the economic growth of the state, improved literacy rate, gender equality, and lowered fertility rate in the last few decades and contributions from the private sector have their share in the public health success of the state. In spite of some flaws and challenges, the Tamil Nadu Model remains the prototype health care delivery system in resource-limited settings which can be emulated by other states also toward a better health care delivery system.

Method: Cross sectional study including adult cancer patients admitted to the emergency service (September-December/2011 with a minimum length of hospital stay of two hours. Student’s t-test and Pearson chi-square test were used to compare the means. Results: 191 patients were enrolled, 47.6% elderly, 64.4% women, 75.4% from the city of Recife and greater area. The symptom prevalent at admission was pain (46.6%. 4.2% of patients were linked to palliative care and 2.1% to home care. The most prevalent cancers: cervix (18.3%, breast (13.6% and prostate (10.5%; 70.7% were in advanced stages (IV, 47.1%; 39.4% without any cancer therapy. Conclusion: Patients sought the emergency service on account of pain, probably due to the incipient coverage of palliative and home care. These actions should be included to oncologic therapy as soon as possible to minimize the suffering of the patient/family and integrate the skills of oncologists and emergency professionals.

    The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1,073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.This guideline was developed through a collaboration between the American Cancer Society and the American Society of Clinical Oncology and has been published jointly by invitation and consent in both CA: A Cancer Journal for

    The HER2 receptor is overexpressed in approximately 20% of breast cancers and is associated with tumorigenesis, metastasis, and a poor prognosis. Trastuzumab is a first-line targeted drug used against HER2(+) breast cancers; however, at least 50% of HER2(+) tumors develop resistance to trastuzumab. To treat these patients, trastuzumab-based antibody-drug conjugates (ACDs) have been developed and are currently used in the clinic. Despite their high efficacy, the long circulation half-life and non-specific binding of cytotoxic ADCs can result in systemic toxicity. In addition, standard ADCs do not provide an image-guided mode of administration. Here, we have developed a two-component, two-step, pre-targeting drug delivery system integrated with image guidance to circumvent these issues. In this strategy, HER2 receptors are pre-labeled with a functionalized trastuzumab antibody followed by the delivery of drug-loaded nanocarriers. Both components are cross-linked by multiple bioorthogonal click reactions in situ on the surface of the target cell and internalized as nanoclusters. We have explored the efficacy of this delivery strategy in HER2(+) human breast cancer models. Our therapeutic study confirms the high therapeutic efficacy of the new delivery system, with no significant toxicity.

    Photodynamic therapy (PDT) is a promising alternative approach for improved cancer treatment. In PDT, a photosensitizer (PS) is administered that can be activated by light of a specific wavelength, which causes selective damage to the tumor and its surrounding vasculature. The success of PDT is limited by the difficulty in administering photosensitizers (PSs) with low water solubility, which compromises the clinical use of several molecules. Incorporation of PSs in nanostructured drug delivery systems, such as polymeric nanoparticles (PNPs), solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), gold nanoparticles (AuNPs), hydrogels, liposomes, liquid crystals, dendrimers, and cyclodextrin is a potential strategy to overcome this difficulty. Additionally, nanotechnology-based drug delivery systems may improve the transcytosis of a PS across epithelial and endothelial barriers and afford the simultaneous co-delivery of two or more drugs. Based on this, the application of nanotechnology in medicine may offer numerous exciting possibilities in cancer treatment and improve the efficacy of available therapeutics. Therefore, the aim of this paper is to review nanotechnology-based drug delivery systems for photodynamic therapy of cancer.

    Over the past 15 years, the multidisciplinary team management of many medical conditions especially cancers has increasingly taken a prominent role in patient management in many hospitals and medical centres in the developed countries. In the United Kingdom, it began to gain prominence following the Calman-Heine report in 1995 which suggested that each Cancer Unit in a hospital should have in place arrangements for non-surgical oncological input into services, with a role for a non-surgical oncologist. The report further suggested that a lead clinician with a well established interest in cancer care should be appointed to organise and coordinate the whole range of cancer services provided within the Cancer Unit. Many people have argued that the multidisciplinary team management of patients has resulted in better care and improved survival. However, there are barriers to the optimal effectiveness of the multidisciplinary team. This paper aims to review various studies on the effectiveness of the multidisciplinary team in the management of cancer patients and also discuss some of the barriers to the multidisciplinary team.

    In this study, we examine the feasibility of cognitive behavior therapy (CBT) for children with anxiety in primary care, using two modes of treatment delivery. A total of 48 parents and youth (8-13) with anxiety disorders were randomly assigned to receive 10-sessions of CBT either delivered by a child anxiety specialist in the primary care clinic or implemented by the parent with therapist support by telephone (i.e., face-to-face or therapist-supported bibliotherapy). Feasibility outcomes including satisfaction, barriers to treatment participation, safety, and dropout were assessed. Independent evaluators, blind to treatment condition, administered the Anxiety Disorders Interview Schedule for Children (ADIS) and the Clinical Global Impression of Improvement (CGI-I) at baseline, post-treatment and 3-month follow-up; clinical self-report questionnaires were also administered. Findings revealed high satisfaction, low endorsement of barriers, low drop out rates, and no adverse events across the two modalities. According to the CGI-I, 58.3%-75% of participants were considered responders (i.e., much or very much improved) at the various time points. Similar patterns were found for remission from "primary anxiety disorder" and "all anxiety disorders" as defined by the ADIS. Clinically significant improvement was seen on the various parent and child self-report measures of anxiety. Findings suggest that both therapy modalities are feasible and associated with significant treatment gains in the primary care setting. (clinicaltrials.gov unique identifier: NCT00769925).

    Full Text Available OBJECTIVE: to analyze nursing care provided to cancer patients with oral mucositis based on the Nursing Process (NP. METHOD: this exploratory, descriptive, cross-sectional and quantitative study was conducted with 213 patients undergoing chemotherapy and/or radiotherapy in two cancer facilities: one philanthropic and one private service. RESULTS: the participants were mainly female, aged 45.8 years old on average, with up to 11 years of schooling and income of up to one times the minimum wage. Severe mucositis was related to chemotherapy associated with radiotherapy. Only 25.3% of the patients reported having received guidance from nurses during their treatment concerning self-care. The perceptions of patients regarding quality of care did not significantly differ between the private and public facilities. The basic human needs mainly affected were comfort, eating, and hygiene. Based on this finding, one NP was established listing the diagnoses, interventions and expected results to establish an ideal, though individualized, standard of nursing care to be provided to these patients. CONCLUSION: to understand oral mucositis is crucial to establish nursing care that includes prevention based on the implementation of an oral care plan.

    Recent studies have demonstrated great therapeutic potential of educating and unleashing our own immune system for cancer treatment. However, there are still major challenges in cancer immunotherapy, including poor immunogenicity of cancer vaccines, off-target side effects of immunotherapeutics, as well as suboptimal outcomes of adoptive T cell transfer-based therapies. Nanomaterials with defined physico-biochemical properties are versatile drug delivery platforms that may address these key technical challenges facing cancer vaccines and immunotherapy. Nanoparticle systems have been shown to improve targeted delivery of tumor antigens and therapeutics against immune checkpoint molecules, amplify immune activation via the use of new stimuli-responsive or immunostimulatory materials, and augment the efficacy of adoptive cell therapies. Here, we review the current state-of-the-art in nanoparticle-based strategies designed to potentiate cancer immunotherapies, including cancer vaccines with subunit antigens (e.g., oncoproteins, mutated neo-antigens, DNA and mRNA antigens) and whole-cell tumor antigens, dendritic cell-based vaccines, artificial antigen-presenting cells, and immunotherapeutics based on immunogenic cell death, immune checkpoint blockade, and adoptive T-cell therapy.

    Conventional therapies for malignant cancer such as chemotherapy and radiotherapy are associated with poor survival rates owing to the development of cellular resistance to cancer drugs and the lack of targetability, resulting in unwanted adverse effects on healthy cells and necessitating the lowering of therapeutic dose with consequential lower efficacy of the treatment. Gene therapy employing different types of viral and non-viral carriers to transport gene(s) of interest and facilitating production of the desirable therapeutic protein(s) has tremendous prospects in cancer treatments due to the high-level of specificity in therapeutic action of the expressed protein(s) with diminished off-target effects, although cancer cell-specific delivery of transgene(s) still poses some challenges to be addressed. Depending on the potential therapeutic target genes, cancer gene therapy could be categorized into tumor suppressor gene replacement therapy, immune gene therapy and enzyme- or prodrug-based therapy. This review would shed light on the current progress of delivery of potentially therapeutic genes into various cancer cells in vitro and animal models utilizing a variety of viral and non-viral vectors.

    Full Text Available Breast cancer aberrantly expresses tissue factor (TF in cancer tissues and cancer vascular endothelial cells (VECs. TF plays a central role in cancer angiogenesis, growth, and metastasis and, as such, is a target for therapy and drug delivery. TF is the cognate receptor of factor VIIa (fVIIa. We have coupled PTX (paclitaxel, also named Taxol with a tripeptide, phenylalanine-phenylalanine-arginine chloromethyl ketone (FFRck and conjugated it with fVIIa. The key aim of the work is to evaluate the antiangiogenic effects of PTX-FFRck-fVIIa against a PTX-resistant breast cancer cell line. Matrigel mixed with VEGF and MDA-231 was injected subcutaneously into the flank of athymic nude mice. Animals were treated by tail vein injection of the PTX-FFRck-fVIIa conjugate, unconjugated PTX, or PBS. The PTX-FFRck-fVIIa conjugate significantly reduces microvessel density in matrigel (p<0.01–0.05 compared to PBS and unconjugated PTX. The breast cancer lung metastasis model in athymic nude mice was developed by intravenous injection of MDA-231 cells expressing luciferase. Animals were similarly treated intravenously with the PTX-FFRck-fVIIa conjugate or PBS. The conjugate significantly inhibits lung metastasis as compared to the control, highlighting its potential to antagonize angiogenesis in metastatic carcinoma. In conclusion, PTX conjugated to fVIIa is a promising therapeutic approach for improving selective drug delivery and inhibiting angiogenesis.

    Complementary and alternative medicine (CAM) use among cancer patients varies according to geographical area, gender, and disease diagnosis. The prevalence of CAM use among cancer patients in the United States has been estimated to be between 7% and 54%. Most cancer patients use CAM with the hope of boosting the immune system, relieving pain, and controlling side effects related to disease or treatment. Only a minority of patients include CAM in the treatment plan with curative intent. This review article focuses on practices belonging to the CAM domains of mind-body medicine, CAM botanicals, manipulative practices, and energy medicine, because they are widely used as complementary approaches to palliative cancer care and cancer symptom management. In the area of cancer symptom management, auricular acupuncture, therapeutic touch, and hypnosis may help to manage cancer pain. Music therapy, massage, and hypnosis may have an effect on anxiety, and both acupuncture and massage may have a therapeutic role in cancer fatigue. Acupuncture and selected botanicals may reduce chemotherapy-induced nausea and emesis, and hypnosis and guided imagery may be beneficial in anticipatory nausea and vomiting. Transcendental meditation and the mindfulness-based stress reduction can play a role in the management of depressed mood and anxiety. Black cohosh and phytoestrogen-rich foods may reduce vasomotor symptoms in postmenopausal women. Most CAM approaches to the treatment of cancer are safe when used by a CAM practitioner experienced in the treatment of cancer patients. The potential for many commonly used botanical to interact with prescription drugs continues to be a concern. Botanicals should be used with caution by cancer patients and only under the guidance of an oncologist knowledgeable in their use.

    Radiotherapy is a successful, time-efficient, well-tolerated, and cost-effective intervention that is crucial for the appropriate delivery of palliative oncology care. The distinction between curative and palliative goals is blurred in many patients with cancer, requiring that treatments be chosen on the basis of factors related to the patient (ie, poor performance status, advanced age, significant weight loss, severe comorbid disease), the cancer (ie, metastatic disease, aggressive histology), or the treatment (ie, poor response to systemic therapy, previous radiotherapy). Goals may include symptom relief at the site of primary tumor or from metastatic lesions. Attention to a patient's discomfort and transportation limitations requires hypofractionated courses, when feasible. Innovative approaches include rapid response palliative care clinics as well as the formation of palliative radiotherapy specialty services in academic centers. Guidelines are providing better definitions of appropriate palliative radiotherapy interventions, and bone metastases fractionation has become the first radiotherapy quality measure accepted by the National Quality Forum. Further advances in the palliative radiation oncology subspecialty will require integration of education and training between the radiotherapy and palliative care specialties.

    2013-10-01

    In March 2010, the Patient Protection and Affordable Care Act as well as its amendments were signed into law. This sweeping legislation was aimed at controlling spiraling healthcare costs and redressing significant disparities in healthcare access and quality. Cancer diagnoses and their treatments constitute a large component of rising healthcare expenditures and, not surprisingly, the legislation will have a significant influence on cancer care in the USA. Because genitourinary malignancies represent an impressive 25% of all cancer diagnoses per year, this legislation could have a profound impact on urologic oncology. To this end, we will present key components of this landmark legislation, including the proposed expansion to Medicaid coverage, the projected role of Accountable Care Organizations, the expected creation of quality reporting systems, the formation of an independent Patient-Centered Outcomes Research Institute, and enhanced regulation on physician-owned practices. We will specifically address the anticipated effect of these changes on urologic cancer care. Briefly, the legal ramifications and current barriers to the statutes will be examined.

    The strategy undertaken by the VNSNY for its survival has been to create a new service delivery model. The design of the SDM is based on a study of organizations, within and outside of health care, that face common challenges in the home health industry today: increased competition, declining reimbursement with escalating costs, and demands for improved outcomes and customer satisfaction. The model that emerged contained several important strategies in its design, including the alignment of team goals with organizational strategic objectives, restructuring teams as multidisciplinary units, redefining the work of teams to include practice improvement and supporting team learning, increasing members' accountability for team not individual performance. The SDM continues to evolve and improve during the process of implementation as lessons emerge from our experience with teams. Preliminary results indicate that the efforts have begun to show improvements in outcomes.

    Full Text Available Abstract Background Teamwork is a key component of the health care renewal strategy emphasized in Quebec, elsewhere in Canada and in other countries to enhance the quality of oncology services. While this innovation would appear beneficial in theory, empirical evidences of its impact are limited. Current efforts in Quebec to encourage the development of local interdisciplinary teams in all hospitals offer a unique opportunity to assess the anticipated benefits. These teams working in hospital outpatient clinics are responsible for treatment, follow-up and patient support. The study objective is to assess the impact of interdisciplinarity on cancer patients and health professionals. Methods/Design This is a quasi-experimental study with three comparison groups distinguished by intensity of interdisciplinarity: strong, moderate and weak. The study will use a random sample of 12 local teams in Quebec, stratified by intensity of interdisciplinarity. The instrument to measure the intensity of the interdisciplinarity, developed in collaboration with experts, encompasses five dimensions referring to aspects of team structure and process. Self-administered questionnaires will be used to measure the impact of interdisciplinarity on patients (health care utilization, continuity of care and cancer services responsiveness and on professionals (professional well-being, assessment of teamwork and perception of teamwork climate. Approximately 100 health professionals working on the selected teams and 2000 patients will be recruited. Statistical analyses will include descriptive statistics and comparative analysis of the impact observed according to the strata of interdisciplinarity. Fixed and random multivariate statistical models (multilevel analyses will also be used. Discussion This study will pinpoint to what extent interdisciplinarity is linked to quality of care and meets the complex and varied needs of cancer patients. It will ascertain to what extent

    Although there are 3 hospice care programs for terminal cancer patients in Taiwan, the medical utilization and expenses for these patients by programs have not been well-explored. The aim of this study was to examine the medical utilization and expenses of terminal cancer patients under different programs of hospice care in the last 90, 30, and 14 days of life.This was a retrospective observational study by secondary data analysis. By using the National Health Insurance claim database and Hospice Shared Care Databases. We identified cancer descents from these databases and classified them into nonhospice care and hospice care groups based on different combination of hospice care received. We then analyzed medical utilization including inpatient care, outpatient care, emergency room visits, and medical expenses by patient groups in the last 90, 30, and 14 days of life.Among 118,376 cancer descents, 46.9% ever received hospice care. Patients had ever received hospice care had significantly lower average medical utilization and expenses in their last 90, 30, and 14 days of life (all P hospice care group had significantly less medical utilization and expenses in the last 90, 30, and 14 days of life (all P hospice care program have different effects on medical care utilization reduction and cost-saving at different stage of the end of life of terminal cancer patients.

    Research suggests that the quality of non-cancer-related care among cancer survivors (CS) is suboptimal. Secondary disease prevention is an important component of survivorship care that has not been previously evaluated. Our aims were (1) to assess the utilization of and adherence to medications and treatments for the secondary prevention of myocardial infarction (MI) in CS versus non-cancer patients (NCP) and (2) to compare temporal trends in cardiovascular care between these two patient cohorts. Linking data from Medicare, pharmacy assistance programs, and cancer registries, we calculated the percentage of individuals receiving preventive medications (statins, β-blockers, angiotensin-converting enzyme inhibitors) and revascularization interventions (angioplasty, stent, bypass surgery) within 90 days after acute MI in CS and propensity score-matched NCP. We assessed trends over time and determined predictors of appropriate preventive care using modified Poisson regression. We identified 1,119 CS and 7,886 NCP. Compared to NCP, more survivors received statins (38 vs. 31 %) and β-blockers (67 vs. 59 %), but fewer underwent bypass surgery (1.5 vs. 2.8 %) after MI. From 1997 to 2004, both survivors and NCP were increasingly prescribed medications to prevent future coronary events. Over the same time period, receipt of bypass surgery was significantly lower among survivors. Co-morbidities, such as depression and lung disease, and demographic factors, such as advanced age and female, were associated with underuse of preventive care among survivors when compared to NCP. Use of preventive medications and procedures has generally improved, but uptake of bypass surgery among CS still lags behind NCP.

  18. Non-viral gene delivery strategies for cancer therapy, tissue engineering and regenerative medicine

    Science.gov (United States)

    Bhise, Nupura S.

    Gene therapy involves the delivery of deoxyribonucleic acid (DNA) into cells to override or replace a malfunctioning gene for treating debilitating genetic diseases, including cancer and neurodegenerative diseases. In addition to its use as a therapeutic, it can also serve as a technology to enable regenerative medicine strategies. The central challenge of the gene therapy research arena is developing a safe and effective delivery agent. Since viral vectors have critical immunogenic and tumorogenic safety issues that limit their clinical use, recent efforts have focused on developing non-viral biomaterial based delivery vectors. Cationic polymers are an attractive class of gene delivery vectors due to their structural versatility, ease of synthesis, biodegradability, ability to self-complex into nanoparticles with negatively charged DNA, capacity to carry large cargo, cellular uptake and endosomal escape capacity. In this thesis, we hypothesized that developing a biomaterial library of poly(betaamino esters) (PBAE), a newer class of cationic polymers consisting of biodegradable ester groups, would allow investigating vector design parameters and formulating effective non-viral gene delivery strategies for cancer drug delivery, tissue engineering and stem cell engineering. Consequently, a high-throughput transfection assay was developed to screen the PBAE-based nanoparticles in hard to transfect fibroblast cell lines. To gain mechanistic insights into the nanoparticle formulation process, biophysical properties of the vectors were characterized in terms of molecular weight (MW), nanoparticle size, zeta potential and plasmid per particle count. We report a novel assay developed for quantifying the plasmid per nanoparticle count and studying its implications for co-delivery of multiple genes. The MW of the polymers ranged from 10 kDa to 100 kDa, nanoparticle size was about 150 run, zeta potential was about 30 mV in sodium acetate buffer (25 mM, pH 5) and 30 to 100

    Ultrasound induced microbubble cavitation can cause enhanced permeability across natural barriers of tumors such as vessel walls or cellular membranes, allowing for enhanced therapeutic delivery into the target tissues. While enhanced delivery of small (100nm) therapeutic carriers into cancer remains unclear and may require a higher pressure for sufficient delivery. Enhanced delivery of larger therapeutic carriers such as FDA approved pegylated poly(lactic-co-glycolic acid) nanoparticles (PLGA-PEG-NP) has significant clinical value because these nanoparticles have been shown to protect encapsulated drugs from degradation in the blood circulation and allow for slow and prolonged release of encapsulated drugs at the target location. In this study, various acoustic parameters were investigated to facilitate the successful delivery of two nanocarriers, a fluorescent semiconducting polymer model drug nanoparticle as well as PLGA-PEG-NP into human colon cancer xenografts in mice. We first measured the cavitation dose produced by various acoustic parameters (pressure, pulse length, and pulse repetition frequency) and microbubble concentration in a tissue mimicking phantom. Next, in vivo studies were performed to evaluate the penetration depth of nanocarriers using various acoustic pressures, ranging between 1.7 and 6.9MPa. Finally, a therapeutic microRNA, miR-122, was loaded into PLGA-PEG-NP and the amount of delivered miR-122 was assessed using quantitative RT-PCR. Our results show that acoustic pressures had the strongest effect on cavitation. An increase of the pressure from 0.8 to 6.9MPa resulted in a nearly 50-fold increase in cavitation in phantom experiments. In vivo, as the pressures increased from 1.7 to 6.9MPa, the amount of nanoparticles deposited in cancer xenografts was increased from 4- to 14-fold, and the median penetration depth of extravasated nanoparticles was increased from 1.3-fold to 3-fold, compared to control conditions without ultrasound, as

    The delivery of HIV care in the initial rapid scale-up of HIV care and treatment was based on existing clinic-based models, which are common in highly resourced settings and largely undifferentiated for individual needs. A new framework for treatment based on variable intensities of care tailored to the specific needs of different groups of individuals across the cascade of care is proposed here. Service intensity is characterised by four delivery components: (i) types of services delivered, (ii) location of service delivery, (iii) provider of health services and (iv) frequency of health services. How these components are developed into a service delivery framework will vary across countries and populations, with the intention being to improve acceptability and care outcomes. The goal of getting more people on treatment before they become ill will necessitate innovative models of delivering both testing and care. As HIV programmes expand treatment eligibility, many people entering care will not be ‘patients’ but healthy, active and productive members of society 1. To take the framework to scale, it will be important to: (i) define which individuals can be served by an alternative delivery framework; (ii) strengthen health systems that support decentralisation, integration and task shifting; (iii) make the supply chain more robust; and (iv) invest in data systems for patient tracking and for programme monitoring and evaluation. La délivrance des soins du VIH dans le déploiement initial rapide des soins et du traitement du VIH a été basée sur des modèles existants dans les cliniques, qui sont courants dans les régions bénéficiant d’importantes ressources et largement indifférenciées pour les besoins individuels. Un nouveau cadre est proposé ici pour le traitement basé selon les intensités variables de soins, adaptés aux besoins spécifiques des différents groupes de personnes à travers la cascade de soins.

    Lack of better understanding of nanoparticles targeted delivery into cancer cells calls for advanced optical microscopy methodologies. Here we present a development of fluorescence microspectroscopy (spectral imaging) based on a white light spinning disk confocal microscope with emission wavelength selection by a liquid crystal tunable filter. Spectral contrasting of images was used to localize polymer nanoparticles and cell membranes labeled with fluorophores that have substantially overlapping spectra. In addition, fluorescence microspectroscopy enabled spatially-resolved detection of small but significant effects of local molecular environment on the properties of environment-sensitive fluorescent probe. The observed spectral shift suggests that the delivery of suitably composed cancerostatic alkylphospholipid nanoparticles into living cancer cells might rely on the fusion with plasma cell membrane.

    RNA interference (RNAi) is a naturally occurring regulatory process that controls posttranscriptional gene expression. Small interfering RNA (siRNA), a common form of RNAi-based therapeutics, offers new opportunities for cancer therapy via silencing specific genes, which are associated to cancer progress. However, clinical applications of RNAi-based therapy are still limited due to the easy degradation of siRNA during body circulation and the difficulty in the delivery of siRNA to desired tissues and cells. Thus, there have been many efforts to develop efficient siRNA delivery systems, which protect siRNA from serum nucleases and deliver siRNA to the intracellular region of target cells. Here, the recent advances in siRNA nanocarriers, which possess tumor-targeting ability are reviewed; various nanoparticle systems and their antitumor effects are summarized. The development of multifunctional nanocarriers for theranostics or combinatorial therapy is also discussed.

    In dendritic cells (DCs)-based cancer immunotherapy, it is important to present the epitope peptide derived from tumor associated antigens (TAAs) on MHC class I in order to induce tumor specific cytotoxic T lymphocytes (CTLs). However, MHC class I molecules generally present the epitope peptides derived from endogenous antigens for DCs but not exogenous ones such as TAAs. Recently, we developed the novel liposomal bubbles (Bubble liposomes) encapsulating perfluoropropane nanobubbles. In this study, we attempted to establish the novel antigen delivery system to induce MHC class I presentation using the combination of ultrasound and Bubble liposomes. Using ovalbumin (OVA) as model antigen, the combination of Bubble liposomes and ultrasound exposure for the DC could induce MHC class I presentation. In addition, the viability of DCs was more than 80%. These results suggest that Bubble liposomes might be a novel ultrasound enhanced antigen delivery tool in DC-based cancer immunotherapy.

    There is substantial heterogeneity in the clinical behavior of pancreatic cancer and in its response to therapy. Some of this variation may be due to differences in delivery of cytotoxic therapies between patients and within individual tumors. Indeed, in 12 patients with resectable pancreatic cancer, we previously demonstrated wide inter-patient variability in the delivery of gemcitabine as well as in the mass transport properties of tumors as measured by computed tomography (CT) scans. However, the variability of drug delivery and transport properties within pancreatic tumors is currently unknown. Here, we analyzed regional measurements of gemcitabine DNA incorporation in the tumors of the same 12 patients to understand the degree of intra-tumoral heterogeneity of drug delivery. We also developed a volumetric segmentation approach to measure mass transport properties from the CT scans of these patients and tested inter-observer agreement with this new methodology. Our results demonstrate significant heterogeneity of gemcitabine delivery within individual pancreatic tumors and across the patient cohort, with gemcitabine DNA incorporation in the inner portion of the tumors ranging from 38 to 74% of the total. Similarly, the CT-derived mass transport properties of the tumors had a high degree of heterogeneity, ranging from minimal difference to almost 200% difference between inner and outer portions of the tumor. Our quantitative method to derive transport properties from CT scans demonstrated less than 5% difference in gemcitabine prediction at the average CT-derived transport value across observers. These data illustrate significant inter-patient and intra-tumoral heterogeneity in the delivery of gemcitabine, and highlight how this variability can be reproducibly accounted for using principles of mass transport. With further validation as a biophysical marker, transport properties of tumors may be useful in patient selection for therapy and prediction of

    Nanomedicine nowadays offers novel solutions in cancer therapy and diagnosis by introducing multimodal treatments and imaging tools in one single formulation. Nanoparticles acting as nanocarriers change the solubility, biodistribution and efficiency of therapeutic molecules, reducing their side effects. In order to successfully  apply these novel therapeutic approaches, efforts are focused on the biological functionalization of the nanoparticles to improve the selectivity towards cancer cells. In this work, we present the synthesis and characterization of novel multifunctionalized iron oxide magnetic nanoparticles (MNPs) with antiCD44 antibody and gemcitabine derivatives, and their application for the selective treatment of CD44-positive cancer cells. The lymphocyte homing receptor CD44 is overexpressed in a large variety of cancer cells, but also in cancer stem cells (CSCs) and circulating tumor cells (CTCs). Therefore, targeting CD44-overexpressing cells is a challenging and promising anticancer strategy. Firstly, we demonstrate the targeting of antiCD44 functionalized MNPs to different CD44-positive cancer cell lines using a CD44-negative non-tumorigenic cell line as a control, and verify the specificity by ultrastructural characterization and downregulation of CD44 expression. Finally, we show the selective drug delivery potential of the MNPs by the killing of CD44-positive cancer cells using a CD44-negative non-tumorigenic cell line as a control. In conclusion, the proposed multifunctionalized MNPs represent an excellent biocompatible nanoplatform for selective CD44-positive cancer therapy in vitro.

    The cancer immunotherapy method uses the specificity of the immune system to provide a more effective than more conventional treatments, such as chemotherapy and radiotherapy. Immunotherapy has two main strategies (passive or active) to organize the immune system. Passive strategies use advantage of tumor-hyperpermeable cells, which have enhanced permeability and retention effects. Nanoparticles due to their better accumulation within tissues and cells of the immune system are well suitable for delivery of immune therapies such as vaccines or adjuvants. In this review, we explained application of nanotechnology in immunotherapy of cancer.

    Full Text Available According to the World Health Organization, breast cancer represents 16% of all cancer cases in women and is the second most common cancer. In the past decades, the mortality among patients with metastasis breast cancer has been reduced significantly via drug delivery by means of nanodiamond therapies, which are both biocompatible and scalable. In this study, we determined a theoretical pathway for the construction of a nanodiamond–tamoxifen complex that will act as a drug delivery vehicle for targeting tumor tissues of breast cancer. The tamoxifen pharmacophore was defined and the binding zone was identified for the electrostatic interaction between tamoxifen and a functionalized site of a nanodiamond particle allowing for attachment of the payload (this drug to the surface of the nanodiamond particle. In addition, an analysis of the intermolecular interaction between the nanodiamond and tamoxifen was conducted, showing three hydrogen bonds complying fully with Lipinski’s rule of five, which states that a compound should have five or fewer hydrogen bonds to be permeating and easily absorbed by the body (qualitative prediction. All calculations were performed using the conceptual Density Functional Theory with the M06 functional and the basis set 6-31G(d. The solvent effect has been taken into account by an implicit model, the conductor like polarizable continuum model.

    Cancer persists as one of the most devastating diseases in the world. Problems including metastasis and tumor resistance to chemotherapy and radiotherapy have seriously limited the therapeutic effects of present clinical treatments. To overcome these limitations, cancer gene therapy has been developed over the last two decades for a broad spectrum of applications, from gene replacement and knockdown to vaccination, each with different requirements for gene delivery. So far, a number of genes and delivery vectors have been investigated, and significant progress has been made with several gene therapy modalities in clinical trials. Viral vectors and synthetic liposomes have emerged as the vehicles of choice for many applications. However, both have limitations and risks that restrict gene therapy applications, including the complexity of production, limited packaging capacity, and unfavorable immunological features. While continuing to improve these vectors, it is important to investigate other options, particularly nonarrival biological agents such as bacteria, bacteriophages, and bacteria-like particles. Recently, many molecular imaging techniques for safe, repeated, and high-resolution in vivo imaging of gene expression have been employed to assess vector-mediated gene expression in living subjects. In this review, molecular imaging techniques for monitoring biological gene delivery vehicles are described, and the specific use of these methods at different steps is illustrated. Linking molecular imaging to gene therapy will eventually help to develop novel gene delivery vehicles for preclinical study and support the development of future human applications.

    Polyphenols are natural compounds found in plants, fruits, chocolate, and beverages such as tea and wine. To date, the majority of polyphenol research shows them to have anticancer activity in cell lines and animal models. Some human clinical trials also indicate possible anticancer benefits are associated with polyphenols. A problem with polyphenols is their short half-life and low bioavailability; thus the use of nanoparticles to enhance their delivery is a new research field. A Pubmed search was conducted to find in vitro, in vivo, and human clinical trials done within the past 10 years involving the use of polyphenols against different cancer types, and for studies done within the past 5 years on the use of nanoparticles to enhance polyphenol delivery. Based on the studies found, it is observed that polyphenols may be a potential alternative or additive therapy against cancer, and the use of nanoparticles to enhance their delivery to tumors is a promising approach. However, further human clinical trials are necessary to better understand the use of polyphenols as well as their nanoparticle-mediated delivery.

    Many chemotherapeutics used for cancer treatments encounter issues during delivery to tumors in vivo and may have high levels of systemic toxicity due to their nonspecific distribution. Various materials have been explored to fabricate nanoparticles as drug carriers to improve delivery efficiency. However, most of these materials suffer from multiple drawbacks, such as limited biocompatibility and inability to engineer spatially addressable surfaces that can be utilized for multifunctional activity. Here, we demonstrate that DNA origami possessed enhanced tumor passive targeting and long-lasting properties at the tumor region. Particularly, the triangle-shaped DNA origami exhibits optimal tumor passive targeting accumulation. The delivery of the known anticancer drug doxorubicin into tumors by self-assembled DNA origami nanostructures was performed, and this approach showed prominent therapeutic efficacy in vivo. The DNA origami carriers were prepared through the self-assembly of M13mp18 phage DNA and hundreds of complementary DNA helper strands; the doxorubicin was subsequently noncovalently intercalated into these nanostructures. After conducting fluorescence imaging and safety evaluation, the doxorubicin-containing DNA origami exhibited remarkable antitumor efficacy without observable systemic toxicity in nude mice bearing orthotopic breast tumors labeled with green fluorescent protein. Our results demonstrated the potential of DNA origami nanostructures as innovative platforms for the efficient and safe drug delivery of cancer therapeutics in vivo.

There are over 200 different types of cancer, each of which gains its nomenclature according to the type of tissue the cell originates in. Many patients who succumb to cancer do not die as a result of the primary tumor, but because of the systemic effects of metastases on other regions away from the original site. One of the aims of cancer therapy is to prevent the metastatic process as early as possible. There are currently many therapies in clinical use, and recent advances in biotechnology lend credence to the potential of nanotechnology in the fight against cancer. Nanomaterials such as carbon nanotubes (CNTs, quantum dots, and dendrimers have unique properties that can be exploited for diagnostic purposes, thermal ablation, and drug delivery in cancer. CNTs are tubular materials with nanometer-sized diameters and axial symmetry, giving them unique properties that can be exploited in the diagnosis and treatment of cancer. In addition, CNTs have the potential to deliver drugs directly to targeted cells and tissues. Alongside the rapid advances in the development of nanotechnology-based materials, elucidating the toxicity of nanoparticles is also imperative. Hence, in this review, we seek to explore the biomedical applications of CNTs, with particular emphasis on their use as therapeutic platforms in oncology.Keywords: carbon nanotubes, cancer, photothermal therapy, drug delivery, cytotoxicity, near infrared

    By its unique advantages over traditional medicine, nanomedicine has offered new strategies for cancer treatment. In particular, the development of drug delivery strategies has focused on nanoscale particles to improve bioavailability. However, many of these nanoparticles are unable to overcome tumor resistance to chemotherapeutic agents. Recently, new opportunities for drug delivery have been provided by oligonucleotides that can self-assemble into three-dimensional nanostructures. In this work, we have designed and developed functional DNA nanostructures to deliver the chemotherapy drug doxorubicin (Dox) to resistant cancer cells. These nanostructures have two components. The first component is a DNA aptamer, which forms a dimeric G-quadruplex nanostructure to target cancer cells by binding with nucleolin. The second component is double-stranded DNA (dsDNA), which is rich in -GC- base pairs that can be applied for Dox delivery. We demonstrated that Dox was able to efficiently intercalate into dsDNA and this intercalation did not affect the aptamer's three-dimensional structure. In addition, the Aptamer-dsDNA (ApS) nanoparticle showed good stability and protected the dsDNA from degradation in bovine serum. More importantly, the ApS&Dox nanoparticle efficiently reversed the resistance of human breast cancer cells to Dox. The mechanism circumventing doxorubicin resistance by ApS&Dox nanoparticles may be predominantly by cell cycle arrest in S phase, effectively increased cell uptake and decreased cell efflux of doxorubicin. Furthermore, the ApS&Dox nanoparticles could effectively inhibit tumor growth, while less cardiotoxicity was observed. Overall, this functional DNA nanostructure provides new insights into the design of nanocarriers to overcome multidrug resistance through targeted drug delivery.

  19. Cell mediated therapeutics for cancer treatment: Tumor homing cells as therapeutic delivery vehicles

    Balivada, Sivasai

    Many cell types were known to have migratory properties towards tumors and different research groups have shown reliable results regarding cells as delivery vehicles of therapeutics for targeted cancer treatment. Present report discusses proof of concept for 1. Cell mediated delivery of Magnetic nanoparticles (MNPs) and targeted Magnetic hyperthermia (MHT) as a cancer treatment by using in vivo mouse cancer models, 2. Cells surface engineering with chimeric proteins for targeted cancer treatment by using in vitro models. 1. Tumor homing cells can carry MNPs specifically to the tumor site and tumor burden will decrease after alternating magnetic field (AMF) exposure. To test this hypothesis, first we loaded Fe/Fe3O4 bi-magnetic NPs into neural progenitor cells (NPCs), which were previously shown to migrate towards melanoma tumors. We observed that NPCs loaded with MNPs travel to subcutaneous melanoma tumors. After alternating magnetic field (AMF) exposure, the targeted delivery of MNPs by the NPCs resulted in a mild decrease in tumor size (Chapter-2). Monocytes/macrophages (Mo/Ma) are known to infiltrate tumor sites, and also have phagocytic activity which can increase their uptake of MNPs. To test Mo/Ma-mediated MHT we transplanted Mo/Ma loaded with MNPs into a mouse model of pancreatic peritoneal carcinomatosis. We observed that MNP-loaded Mo/Ma infiltrated pancreatic tumors and, after AMF treatment, significantly prolonged the lives of mice bearing disseminated intraperitoneal pancreatic tumors (Chapter-3). 2. Targeted cancer treatment could be achieved by engineering tumor homing cell surfaces with tumor proteases cleavable, cancer cell specific recombinant therapeutic proteins. To test this, Urokinase and Calpain (tumor specific proteases) cleavable; prostate cancer cell (CaP) specific (CaP1 targeting peptide); apoptosis inducible (Caspase3 V266ED3)- rCasp3V266ED3 chimeric protein was designed in silico.

    The pitfall of all chemotherapeutics lies in drug resistance and the severe side effects experienced by patients. One way to reduce the off-target effects of chemotherapy on healthy tissues is to alter the biodistribution of drug. This can be achieved in two ways: Passive targeting utilizes shape, size, and surface chemistry to increase particle circulation and tumor accumulation. Active targeting employs either chemical moieties (e.g. peptides, sugars, aptamers, antibodies) to selectively bind to cell membranes or responsive elements (e.g. ultrasound, magnetism, light) to deliver its cargo within a local region. This article will focus on the systemic administration of anti-cancer agents and their ability to home to tumors and, if relevant, distant metastatic sites.

    In many regions of the world plagued by high burdens of disease, there is difficulty in accessing basic medical care. This is often due to logistical constraints and a lack of infrastructure such as roads. Medical aviation can play a major role in addressing some of these crucial issues as it allows for the rapid transport of patients, personnel, and medications to remote-and sometimes otherwise inaccessible-areas. Lesotho is a mountainous nation of 2 million people that provides a good example of medical aviation as a cornerstone in the delivery of health care. The population has a reported HIV seroprevalence of 25%, and many patients live in rural areas that are inaccessible by road. Mission Aviation Fellowship has joined forces with a medical team from the nongovernmental organization Partners In Health in an effort to launch a comprehensive program to address HIV and related problems in rural Lesotho. This medical aviation partnership has allowed for the provision of HIV prevention and treatment services to thousands of people living in the mountains. This commentary describes how medical aviation has been crucial in developing models to address complex, serious health problems in remote settings.

    Nursing research and nurse researchers have been an integral and significant part of the Oncology Nursing Society's (ONS's) history, as evidenced by the development of the Nursing Research Committee within a few years of ONS's establishment. Ruth McCorkle, PhD, RN, FAAN, was the committee's first chairperson in 1979. This was followed by the creation of the Advanced Nursing Research Special Interest Group in 1989 under the leadership of Jean Brown, PhD, RN, FAAN. ONS also began to recognize nurse researchers in 1994 by creating the annual ONS Distinguished Researcher Award to recognize the contributions of a member who has conducted or promoted research that has enhanced the science and practice of oncology nursing. The list of recipients and of their work is impressive and reflects the wide range of our practice areas (see http://bit.ly/1MTC5cp for the recipient list). In addition, the ONS Foundation began funding research in 1981 and has distributed more than $24 million in research grants, research fellowships, and other scholarships, lectures, public education projects, and career development awards (ONS Foundation, 2015). And, in 2006, the Putting Evidence Into Practice resource was unveiled, which provides evidence-based intervention reviews for the 20 most common problems experienced by patients with cancer and their caregivers (www.ons

    Cannabis species have been used as medicine for thousands of years; only since the 1940s has the plant not been widely available for medical use. However, an increasing number of jurisdictions are making it possible for patients to obtain the botanical for medicinal use. For the cancer patient, cannabis has a number of potential benefits, especially in the management of symptoms. Cannabis is useful in combatting anorexia, chemotherapy-induced nausea and vomiting, pain, insomnia, and depression. Cannabis might be less potent than other available antiemetics, but for some patients, it is the only agent that works, and it is the only antiemetic that also increases appetite. Inhaled cannabis is more effective than placebo in ameliorating peripheral neuropathy in a number of conditions, and it could prove useful in chemotherapy-induced neuropathy. A pharmacokinetic interaction study of vaporized cannabis in patients with chronic pain on stable doses of sustained-release opioids demonstrated no clinically significant change in plasma opiates, while suggesting the possibility of synergistic analgesia. Aside from symptom management, an increasing body of in vitro and animal-model studies supports a possible direct anticancer effect of cannabinoids by way of a number of different mechanisms involving apoptosis, angiogenesis, and inhibition of metastasis. Despite an absence of clinical trials, abundant anecdotal reports that describe patients having remarkable responses to cannabis as an anticancer agent, especially when taken as a high-potency orally ingested concentrate, are circulating. Human studies should be conducted to address critical questions related to the foregoing effects.

    Full Text Available Introduction: Ventilator-associated pneumonia is a major morbid outcome among intensive care unit (ICU patients. Providing oral care for intubated patients is an important task by the ICU nursing staff in reducing the mortality and morbidity. The objectives of this study were to evaluate the attitudes and knowledge of ICU nurses regarding oral care delivery to critically ill patients in Saudi Arabian ICUs. The findings were further correlated to the presence of healthcare quality accreditation of the institution. Materials and Methods: The nurses′ knowledge, attitudes, and healthcare quality accreditation status of the hospital were recorded. Two hundred fifteen nurses conveniently selected from 10 random hospitals were included in this study from Riyadh city, Saudi Arabia. This is a cross-sectional study in the form of a questionnaire. Results: When comparing the knowledge of the participants to their level of education, there was no statistically significant difference between the two groups of nurses. The majority of the nurses agreed that the oral cavity is difficult to clean and that oral care delivery is a high priority for mechanically ventilated patients. Furthermore, there was no statistically significant difference in the attitudes between nurses working in accredited and nonaccredited hospitals. Conclusion: The presence of healthcare quality accreditation did not reflect any significance in attitudes or knowledge of the ICU nurses in regard to mechanically ventilated patients. Factors affecting oral care delivery should be evaluated on the personal and institutional level to achieve better understanding of them.

    Full Text Available Background: The purpose of this discussion is to explore the theory, evidence base, and practice of Qigong for individuals with cancer. Questions addressed are: What is qigong? How does it work? What evidence exists supporting its practice in integrative oncology? What barriers to wide-spread programming access exist? Methods: Sources for this discussion include a review of scholarly texts, the Internet, PubMed, field observations, and expert opinion. Results: Qigong is a gentle, mind/body exercise integral within Chinese medicine. Theoretical foundations include Chinese medicine energy theory, psychoneuroimmunology, the relaxation response, the meditation effect, and epigenetics. Research supports positive effects on quality of life (QOL, fatigue, immune function and cortisol levels, and cognition for individuals with cancer. There is indirect, scientific evidence suggesting that qigong practice may positively influence cancer prevention and survival. No one Qigong exercise regimen has been established as superior. Effective protocols do have common elements: slow mindful exercise, easy to learn, breath regulation, meditation, emphasis on relaxation, and energy cultivation including mental intent and self-massage. Conclusions: Regular practice of Qigong exercise therapy has the potential to improve cancer-related QOL and is indirectly linked to cancer prevention and survival. Wide-spread access to quality Qigong in cancer care programming may be challenged by the availability of existing programming and work force capacity.

    In the present study, we would like to evaluate the efficacy of modified metal oxide nanoparticles (NPs) as cancer antigen delivery vehicles for macrophage (MФs) based antitumor vaccine. The cobalt oxide nanoparticles (CoO NPs) were promising tools for delivery of antigens to antigen presenting cells and have induced an antitumor immune response. Synthesized CoO NPs were modified by N-phosphonomethyliminodiacetic acid (PMIDA), facilitated the conjugation of lysate antigen, i.e. cancer antigen derived from lysis of cancer cells. The cancer cell lysate antigen conjugated PMIDA-CoO NPs (Ag-PMIDA-CoO NPs) successfully activated macrophage (MФ) evident by the increasing the serum IFN-γ and TNF-α level. Immunization of mice with the Ag-PMIDA-CoO NPs constructed an efficient immunological adjuvant induced anticancer IgG responses, and increased the antibody dependent cellular cytotoxicity (ADCC) response than only lysate antigen treated group to combat the cancer cell. The nanocomplexes enhanced the anticancer CD4(+)T cell response in mice. The result showed that Ag-PMIDA-CoO NPs can stimulate the immune responses over only lysate antigens, which are the most important findings in this study. These NP-mediated Ag deliveries may significantly improve the anticancer immune response by activating MФs and may act as adjuvant and will balance the pro-inflammatory and anti-inflammatory immunoresponse. The crosstalk between the activated MФ with other immune competent cells will be monitored by measuring the cytokines which illustrate the total immunological network setups.

    AIM: To determine the outcome of esophageal cancer patients referred for palliative care, in Gorgan and Gonbad gastrointestinal clinics, northeast of Iran.METHODS: This cross-sectional study was done on inoperable esophageal cancer cases referred to gastrointestinal clinics in Gorgan and Gonbad city (2005-2006). Demographic data were collected during the procedure and cases were followed up every one month. Improvement proportion was calculated with 95% confidence interval, to determine the rate of improvement. Survival analysis and Kaplan-Meier methods were used to estimate the duration of palliative care effectiveness.RESULTS: We recruited 39 cases into the study. Squamous cell carcinoma was the most prevalent (92.3%). The middle third of the esophagus was involved predominantly (51.3%). Dilation was the most preferred method (89.7%) and stenting was done in 4 cases. Decreasing dysphagia score was not related to palliation method or pathology type of carcinoma. Age of the patients was significantly related to the improvement of dysphagia score. Mean survival time was 137.6d and median was 103d.CONCLUSION: Results of this study showed a low survival rate after palliative care in esophageal cancer cases despite dysphagia scores' improvement after dilating or stenting.

    Cancer is a generic term that encompasses a group of diseases characterized by an uncontrolled proliferation of cells. There are over 200 different types of cancer, each of which gains its nomenclature according to the type of tissue the cell originates in. Many patients who succumb to cancer do not die as a result of the primary tumor, but because of the systemic effects of metastases on other regions away from the original site. One of the aims of cancer therapy is to prevent the metastatic process as early as possible. There are currently many therapies in clinical use, and recent advances in biotechnology lend credence to the potential of nanotechnology in the fight against cancer. Nanomaterials such as carbon nanotubes (CNTs), quantum dots, and dendrimers have unique properties that can be exploited for diagnostic purposes, thermal ablation, and drug delivery in cancer. CNTs are tubular materials with nanometer-sized diameters and axial symmetry, giving them unique properties that can be exploited in the diagnosis and treatment of cancer. In addition, CNTs have the potential to deliver drugs directly to targeted cells and tissues. Alongside the rapid advances in the development of nanotechnology-based materials, elucidating the toxicity of nanoparticles is also imperative. Hence, in this review, we seek to explore the biomedical applications of CNTs, with particular emphasis on their use as therapeutic platforms in oncology.

    Active in the United States for the past 25 years, the women's health movement was originally an outgrowth of the larger feminist movement and shares many of the same assumptions. The women's health movement has been successful in increasing public awareness of the problems involved in the delivery of health care to women and effecting changes in that health care. This article seeks to identify societal contributions and specific events that resulted in the occurrence of this social reform movement, enumerate some of the accomplishments, and suggest why health care providers would benefit by understanding this phenomenon.

    The aim of the present study was to identify what hospitalized cancer patients expect from nurses in terms of the care they receive. The specific aims of this study were: (i) to identify those individuals to whom the patients felt closest in the hospital setting and (ii) to evaluate nurses' management of cancer patients during their stay in the hospital. The sample included patients hospitalized at Ege University Hospital and Suat Seren District Hospital, Izmir, Turkey. We found significant differences between the scores of satisfaction and dissatisfaction and gender age, education, occupation, type of cancer and the mode of treatment (p patients reported that nursing management was unsatisfactory. Some demographic factors such as cultural and social status affected patients' expectations.

    Personalized medicine is revolutionizing cancer care and creating new expectations among oncologists and patients. At present the benefit is still marginal, however, and must be understood as incremental. In addition, cultural and resource disparities limit the sustainability of new cancer therapies on a global scale. Adequate instruments are needed to enable our exercise of sound and honest judgment in distinguishing breakthrough treatments from those that yield only marginal or doubtful improvements, and to develop strategies for formulation and correct application of balanced guidelines for sustainable cancer care. Professionalism requires that the acquisition of knowledge and skills go hand in hand with moral education in the intellectual virtues of humility, perseverance, adaptability, communicativeness, and commitment to resist self-deception or conflicts of interest. Hidden curricula undermine the moral values of medicine: these must be understood and uncovered. We should possess a special body of knowledge, skills, and values that allow us to change our practices when appropriate and to be stewards of society's limited resources through proper communication with our patients and families. In the era of personalized oncology and global issues of sustainability, professional authenticity and integrity in cancer clinical practice are key to bridging the gaps between true and false expectations of patients and the public.

    Full Text Available Background: Limited information exists on primary care physicians’ (PCPs use of the prostate-specific antigen (PSA test by patient risk category. We describe PCP responses to hypothetical patient scenario (PS involving PSA testing among high-risk asymptomatic men. Methods: Data were from the 2007 to 2008 National Survey of Primary Care Physicians’ Practices Regarding Prostate Cancer Screening. PS#1: healthy 55-year-old white male with no family history of prostate cancer; PS#2: healthy 45-year-old African American male with no family history of prostate cancer; and PS#3: healthy 50-year-old male with a family history of prostate cancer. Data were analyzed in SAS/SUDAAN. Results: Most PCPs indicated that they generally discuss the possible benefits/risks of PSA testing with the patient and then recommend the test (PS#1-PS#3 range, 53.4%-68.7%; P < .001; only about 1% reported discussing and then recommending against the test. For PS#3, compared to PS#1 and #2, PCPs were more likely to discuss and recommend the test or attempt to persuade the patient who initially declines the test. For PS#3, all clinicians generally would order/discuss the PSA test and not rely on the patient to ask. Conclusion: Clinicians treat family history as an important reason to recommend, persuade, and initiate PSA testing.

    Full Text Available Objective: To describe the pathways of care experienced by women with breast cancer receiving radiotherapy. Methodology: It is a descriptive, exploratory and qualitative study, conducted among women in the Radiotherapy Clinic of a Federal University in the South of Brazil. The participants were six women affected by breast cancer who were receiving radiotherapy. Data were collected through semi-structured interviews from March 2006 to December 2007. Results:The data were analyzed according to the operationalization of thematic analysis, emerging two categories: The plots of the pathways of care, and Overcoming the cancer diagnosis. Conclusions: It was perceived that pathways experienced by women affected by breast cancer involve both barriers and facilitators regarding access to health services, their relationship with professionals, and their ability to overcome. It is also considered important to have knowledge about the diagnosis of the disease in order to be an active person in this process. It is important to have well prepared health professionals and services, in order to accept women in ill situations, since support and guidance are essential to their recovery.

    Continuity of care is integral to the quality and safety of care provided to people with cancer and their carers. Further evidence is required to examine the contribution Nurse Cancer Care Coordinator (NCCC) roles make in improving the continuity. The aim of the present study was to clarify the assumptions underpinning the NCCC roles and provide a basis for ongoing evaluation. The project comprised a literature review and a qualitative study to develop program logic. The participants who were purposively sampled included policy makers, practitioners, patient advocates, and researchers. Both the literature and participant reports found that NCCC roles are diverse and responsive to contextual influences to coordinate care at the individual (patient), organisational, and systems levels. The application of the program logic for the development of NCCC roles was explored. The conceptualisation of NCCC roles was also examined in relation to Boundary Spanning and Relational Coordination theory. Further research is required to examine how NCCCs contribute to improving equity, safety, quality and coordination of care. The project has implications for research, policy and practice, and makes explicit existing assumptions to provide a platform for further development and evaluation of these roles.

    The life of a mother undergoes a dramatic change after a child is diagnosed with cancer. The present study aimed to determine effects on the everyday life process and health status of mothers with children suffering from leukemia. This qualitative study was based on a grounded theory approach with sixteen mothers. The results indicate that after onset of disease in their children, they marginalized their own health and tied their identities to taking care of the child and keeping the child healthy by ignoring themselves, becoming imprisoned in a taking-care-of-the-child position, and trying very hard for seek balance and stability Enduring physical pressures on the one hand, and constantly attempting to achieve balance and stability in family processes on the other hand, gradually cause exhaustion. It seems that health care providers and nurses should pay much more attention to the health status of this group of mothers.

    Full Text Available Abstract Background During the 1990s, health care restructuring in Nova Scotia resulted in downsized hospitals, reduced inpatient length of stay, capped physician incomes and restricted practice locations. Concurrently, the provincial homecare program was redeveloped and out-of-hospital cancer deaths increased from 20% (1992 to 30% (1998. These factors all pointed to a transfer of end-of-life inpatient hospital care to more community-based care. The purpose of this study was to describe the trends in the provision of Family Physician (FP visits to advanced cancer patients in Nova Scotia (NS during the years of health care restructuring. Methods Design Secondary multivariate analysis of linked population-based datafiles including the Queen Elizabeth II Health Sciences Centre Oncology Patient Information System (NS Cancer Registry, Vital Statistics, the NS Hospital Admissions/Separations file and the Medical Services Insurance Physician Services database. Setting Nova Scotia, an eastern Canadian province (population: 950,000. Subjects: All patients who died of lung, colorectal, breast or prostate cancer between April 1992 and March 1998 (N = 7,212. Outcome Measures Inpatient and ambulatory FP visits, ambulatory visits by location (office, home, long-term care facility, emergency department, time of day (regular hours, after hours, total length of inpatient hospital stay and number of hospital admissions during the last six months of life. Results In total, 139,641 visits were provided by family physicians: 15% of visits in the office, 10% in the home, 5% in the emergency department (ED, 5% in a long-term-care centre and 64% to hospital inpatients. There was no change in the rate of FP visits received for office, home and long-term care despite the fact that there were 13% fewer hospital admissions, and length of hospital stay declined by 21%. Age-sex adjusted estimates using negative binomial regression indicate a decline in hospital inpatient FP

    Familial adenomatous polyposis (FAP) is an inherited condition secondary to germline mutations in the APC gene, thus resulting in the formation of hundreds of colonic adenomas that eventually progress into colon cancer. Surgical removal of the colon remains the only treatment option to avoid malignancy, as long-term exposure to chemopreventive agents such as sulindac (a non-steroidal anti-inflammatory drug) and silymarin (phytoestrogen) is not feasible. Here, we have developed a multistage silicon-based drug delivery platform for sulindac and silymarin that preferentially interacts with colon cancer cells as opposed to normal intestinal mucosa. Preferential binding and internalization of these drugs into colon cancer cells was obtained using a targeting strategy against the protein meprin A, which we demonstrate is overexpressed in human colon cancer cells and in the small intestine of Apc(Min/+) mice. We propose that this delivery system could potentially be used to reduce drug-induced side effects in FAP patients, thus enabling long-term prevention of adenoma formation.

    Full Text Available The last decade has witnessed enormous advances in the development and application of nanotechnology in cancer detection, diagnosis, and therapy culminating in the development of the nascent field of “cancer nanomedicine.” A nanoparticle as per the National Institutes of Health (NIH guidelines is any material that is used in the formulation of a drug resulting in a final product smaller than 1 micron in size. Nanoparticle-based therapeutic systems have gained immense popularity due to their ability to overcome biological barriers, effectively deliver hydrophobic therapies, and preferentially target disease sites. Currently, many formulations of nanocarriers are utilized including lipid-based, polymeric and branched polymeric, metal-based, magnetic, and mesoporous silica. Innovative strategies have been employed to exploit the multicomponent, three-dimensional constructs imparting multifunctional capabilities. Engineering such designs allows simultaneous drug delivery of chemotherapeutics and anticancer gene therapies to site-specific targets. In lung cancer, nanoparticle-based therapeutics is paving the way in the diagnosis, imaging, screening, and treatment of primary and metastatic tumors. However, translating such advances from the bench to the bedside has been severely hampered by challenges encountered in the areas of pharmacology, toxicology, immunology, large-scale manufacturing, and regulatory issues. This review summarizes current progress and challenges in nanoparticle-based drug delivery systems, citing recent examples targeted at lung cancer treatment.

    2008-08-01

    Various surveys show that interest in complementary and alternative medicine (CAM) is high among cancer patients. Patients want to explore all options that may help their treatment. Many CAM modalities offer patients an active role in their self-care, and the resulting sense of empowerment is very appealing. On the other hand, many unscrupulous marketeers promote alternative cancer "cures," targeting cancer patients who are particularly vulnerable. Some alternative therapies can hurt patients by delaying effective treatment or by causing adverse effects or detrimental interactions with other medications. It is not in the best interest of cancer patients if they cannot get appropriate guidance on the use of CAM from the health care professionals who are part of their cancer care team. The Integrative Medicine Service at Memorial Sloan-Kettering Cancer Center in New York was established in 1999 to address patient interest in cam, to incorporate helpful complementary therapies into each patient's overall treatment management, to guide patients in avoiding harmful alternative therapies, and to develop prospective research to evaluate the efficacy of CAM modalities.

    The integration of diagnosis and therapy into one nanoplatform, known as theranostics, has attracted increasing attention in the biomedical areas. Herein, we first present a cancer cell targeting imaging and drug delivery system based on engineered thioether-bridged periodic mesoporous organosilica nanoparticles (PMOs). The PMOs are stably and selectively conjugated with near-infrared fluorescence (NIRF) dye Cyanine 5.5 (Cy5.5) and anti-Her2 affibody on the outer surfaces to endow them with excellent NIRF imaging and cancer targeting properties. Also, taking the advantage of the thioether-group-incorporated mesopores, the release of chemotherapy drug doxorubicin (DOX) loaded in the PMOs is responsive to the tumor-related molecule glutathione (GSH). The drug release percentage reaches 84.8% in 10 mM of GSH solution within 24 h, which is more than 2-fold higher than that without GSH. In addition, the drug release also exhibits pH-responsive, which reaches 53.6% at pH 5 and 31.7% at pH 7.4 within 24 h. Confocal laser scanning microscopy and flow cytometry analysis demonstrate that the PMOs-based theranostic platforms can efficiently target to and enter Her2 positive tumor cells. Thus, the smart imaging and drug delivery nanoplatforms induce high tumor cell growth inhibition. Meanwhile, the Cy5.5 conjugated PMOs perform great NIRF imaging ability, which could monitor the intracellular distribution, delivery and release of the chemotherapy drug. In addition, cell viability and histological assessments show the engineered PMOs have good biocompatibility, further encouraging the following biomedical applications. Over all, the systemically engineered PMOs can serve as a novel cancer cell targeting imaging and drug delivery platform with NIRF imaging, GSH and pH dual-responsive drug release, and high tumor cell targeting ability.

  10. Spatiotemporally synchronized cancer combination therapy using photo-activated nanoparticle drug delivery systems (Conference Presentation)

    Science.gov (United States)

    Hasan, Tayyaba

    2016-03-01

    This talk will introduce a new nanotechnology platform for cancer combination therapy that utilizes near infrared light activation not only for photodynamic damage but also as an extrinsic mechanism to initiate release of complimentary drugs to suppress dynamic bursts in molecular signaling networks that promote tumor cell survival and treatment escape. The goal is to achieve co-delivery with concomitant activity of photodynamic, molecular inhibitor and chemotherapeutic agents, selectively within the tumor. This approach overcomes challenges in achieving synergistic interactions using sequential drug delivery. Conventional drug delivery is compromised by the differential pharmacokinetics of individual agents and potentially antagonistic effects—such as vascular shutdown by one agent that limits delivery of the second. Here, photodynamic damage—which efficiently kills drug-resistant cells via damage of common proteins involved in drug-resistance (such as anti-apoptosis factors and drug-efflux transporters)—is synchronized spatially and temporally with the photo-initiated release of complimentary agents—to enable full interaction amongst the individual therapies. This spatiotemporal synchronization offers new prospects for exploiting time-sensitive synergistic interactions. Specific implementations of these concepts will be presented in preclinical models of cancer. Strategies to enable molecular-targeting of cancer cells via site-specific attachment of targeting moieties to the outer lipid shell of these nanovehicles will also be discussed. If successful in humans, this new paradigm for synchronized, tumor-focused combination therapy will ultimately supersede the present use of chronic drug injection by increasing efficacy per cycle whilst reducing systemic exposure to toxic drugs.

    2011-06-01

    Full Text Available Abstract Background Ovarian cancer is the leading cause of death among women suffering from gynaecological malignancies in the Western world. Worldwide, approximately 200,000 women are diagnosed with the disease each year. This article deals with the health care seeking and symptom interpretation process among Danish women, who have a very high mortality rate. Methods The health seeking and symptom interpretation process was analysed via combining study methods. The material consisted of registry data dealing with the use of public health care and hospital services of Danish women, newly diagnosed with ovarian cancer. These results were combined with findings from semi-structured qualitative research interviews on women's bodily experiences with symptom development. Results A number of 663 Danish women with ovarian cancer attended 27 different kinds of primary health care providers in a total of 14,009 visits during 2007. The women also had 6,214 contacts with various hospitals, and obtained 562 different diagnoses. From the main theme "Women's experiences with the onset of symptoms" three sub-themes were identified: "Bodily sensations", "From bodily sensation to symptom", and "Health seeking and treatment start". In all cases the General Practitioner represented the first contact to public health care, acting as gate-keeper to specialist and hospital referral. The women were major users of public health care throughout the diagnostic process and subsequent treatment. All women held personal knowledge concerning the onset of their symptoms. The early symptoms of ovarian cancer might be uncharacteristic and non-disease-specific when interpreted as personal experiences, but they had similarities when analysed together. Conclusions Diagnostic delay in ovarian cancer seems far from being exclusively a medical problem, as the delay proved to be influenced by organisational, cultural, and social factors, too. Initiatives facilitating the diagnostic

    Multi-disciplinary team work among visiting doctors, nurses, care managers and pharmacists located close to the patient's home is essential for smooth transition of a palliative care patient from hospital care to palliative home care and should be set up prior to the patient's discharge from the hospital. Palliative home care physicians should have knowledge of the fundamental support by the government to spare excessive cost to the patients. As for cancer pain management, opioid-centered analgesic therapies have lead to better quality home care for patients. In Japan, although oxycodone SRs and fentanyl patches are available besides morphine, there is no rescue opioid other than morphine. On the other hand, some cancer pain refractory to opioids such as neuropathic cancer pain should be carefully treated by adjuvant analgesics in conjunction with non-pharmacological treatments.

    BACKGROUND: Many sub-Saharan countries, including Ghana, have introduced policies to provide free medical care to pregnant women. The impact of these policies, particularly on access to health services among the poor, has not been evaluated using rigorous methods, and so the empirical basis for defending these policies is weak. In Ghana, a recent report also cast doubt on the current mechanism of delivering free care--the National Health Insurance Scheme. Longitudinal surveillance data from t...

Patient-centered care is based on patients' needs rather than on prognosis, and takes into account the emotional and psychosocial aspects of the disease. This model may be applied to elderly patients, who present comorbid diseases, but it also fits with the needs of younger fit patients. A specialized multidisciplinary team coordinated by experienced medical oncologists and including pharmacists, psychologists, nurses, and social assistance providers should carry out home care. Other professional figures may be required depending on patients' needs. Every effort should be made to achieve optimal coordination between the health professionals and the reference hospital and to employ shared evidence-based guidelines, which in turn guarantee safety and efficacy. Comprehensive care has to be easily accessible and requires a high level of education and knowledge of the disease for both the patients and their caregivers. Patient-centered home care represents an important tool to improve quality of life and help cancer patients while also being cost effective.Keywords: cancer, home care

    Full Text Available BACKGROUND: Colorectal cancer (CRC has a high prevalence in western countries. Diagnosis and treatment of CRC is complex and requires multidisciplinary collaboration across the interface of health care sectors. In Germany, a new nationwide established program aims to provide quality information of healthcare delivery across different sectors. Within this context, this study describes the development of a set of quality indicators charting the whole pathway of CRC-care including data specifications that are necessary to operationalize these indicators before practice testing. METHODS: Indicators were developed following a systematic 10 step modified 'RAND/UCLA Appropriateness Method' which involved a multidisciplinary panel of thirteen participants. For each indicator in the final set, data specifications relating to sources of quality information, data collection procedures, analysis and feedback were described. RESULTS: The final indicator set included 52 indicators covering diagnostic procedures (11 indicators, therapeutic management (28 indicators and follow-up (6 indicators. In addition, 7 indicators represented patient perspectives. Primary surgical tumor resection and pre-operative radiation (rectum carcinoma only were perceived as most useful tracer procedures initiating quality data collection. To assess the quality of CRC care across sectors, various data sources were identified: medical records, administrative inpatient and outpatient data, sickness-funds billing code systems and patient survey. CONCLUSION: In Germany, a set of 52 quality indicators, covering necessary aspects across the interfaces and pathways relevant to CRC-care has been developed. Combining different sectors and sources of health care in quality assessment is an innovative and challenging approach but reflects better the reality of the patient pathway and experience of CRC-care.

    Purpose Survivorship care plans (SCP) are recommended for all cancer patients and could be especially useful to survivors 65 years and over (“older”). This study examined receipt of SCPs among older breast cancer survivors and whether SCPs were associated with improved patient-reported outcomes. Methods Three hundred and twenty-eight older women diagnosed with invasive, nonmetastatic breast cancer between 2007–2011 were recruited from 78 cooperative-group sites. Participants completed telephone interviews at baseline and 1-year posttreatment. Regression analyses examined SCP receipt (yes/no) and functioning (EORTC-QLQ-C30), cancer worry, and experiences of survivorship care (care coordination, knowledge). Results Only 35 % of women received SCPs. For each 1-year increase in age, there was a 5 % lower odds of receiving an SCP (odds ratio (OR)=0.94, 95 % confidence interval (CI) 0.91–0.98, p=0.007). Besides age, no other factor predicted SCPs. SCP receipt was associated with greater knowledge and understanding of requisite follow-up care (p<0.05); however, functioning was not significantly different among those with vs. without SCPs. Conclusions Receipt of care plans was limited. SCPs improved understanding of breast cancer follow-up care among older survivors, but did not impact functioning one year post-treatment. Implications for Cancer Survivors To impact functioning and salient needs of the growing cohort of older survivors, survivorship care plans likely should be tailored to geriatric-specific issues. To improve functioning, SCP content should expand to include exercise, nutrition, polypharmacy, social support and management of symptom burden from cancer, and other comorbid conditions. To improve follow-up care for cancer survivors, SCPs should delineate shared care roles between oncology and primary care in managing recurrence surveillance, screening, and cancer sequelae.

    The tetraiodothyroacetic acid (tetrac) component of nano-diamino-tetrac (NDAT) is chemically bonded via a linker to a poly(lactic-co-glycolic acid) nanoparticle that can encapsulate anticancer drugs. Tetrac targets the plasma membrane of cancer cells at a receptor on the extracellular domain of integrin αvβ3. In this study, we evaluate the efficiency of NDAT delivery of paclitaxel and doxorubicin to, respectively, pancreatic and breast cancer orthotopic nude mouse xenografts. Intra-tumoral drug concentrations were 5-fold (paclitaxel; P<0.001) and 2.3-fold (doxorubicin; P<0.01) higher than with conventional systemic drug administration. Tumor volume reductions reflected enhanced xenograft drug uptake. Cell viability was estimated by bioluminescent signaling in pancreatic tumors and confirmed an increased paclitaxel effect with drug delivery by NDAT. NDAT delivery of chemotherapy increases drug delivery to cancers and increases drug efficacy. PMID:28243091

    The objective of this study was to evaluate the possibility of using GE11-polyethylene glycol-polyethylenimine (GE11-PEG-PEI) for targeted gene delivery to treat epidermal growth factor receptor (EGFR)-overexpressing laryngeal cancer. This study described the design, characterization, and in vitro and in vivo study of the nanocarrier GE11-PEG-PEI for gene delivery to treat laryngeal cancer. Analysis of the sizes and zeta potentials indicated that the formation of PEGylated complexes was dependent on the N/P ratio, and these complexes were capable of binding plasmid DNA and condensing DNA into small positively charged nanoparticles. The results also revealed that GE11-PEG-PEI had a weaker effect on cell survival in vitro. Gene transfection was performed on human laryngeal cancer Hep-2 cells in vitro and in vivo. Both the in vitro and in vivo results demonstrated that GE11-PEG-PEI had greater transfection efficiency than mPEG-PEI. Compared with mPEG-PEI/pORF-hTRAIL and saline, GE11-PEG-PEI/pORFh-TRAIL significantly (p < 0.05) reduced tumor growth in nude mice with laryngeal cancer. Moreover, the GE11-PEG-PEI/pORF-hTRAIL-treated groups showed more apoptosis than the mPEG-PEI/pORF-hTRAIL-treated groups. Therefore, our results showed that the peptide GE11 conjugated to PEG-PEI delivered significantly more genes to EGFR-overexpressing laryngeal cancer cells in vivo, indicating that GE11-PEG-PEI may be a suitable gene vector for treating EGFR-overexpressing laryngeal cancer.

    Full Text Available The positive outcomes associated with Patient Engagement (PE have been strongly supported by the recent literature. However, this concept has been marginally addressed in the context of cancer. Limited attention has also received the role of informal caregivers in promoting physical and psychological well-being of patients, as well as the interdependence of dyads. The Cancer Dyads Group Intervention (CDGI is a couple-based psychosocial intervention developed to promote engagement in management behaviors, positive health outcomes, and the quality of the relationship between cancer patients and their informal caregivers. The article examines the ability of the CDGI to promote adaptive coping behaviors and the perceived level of closeness by comparing cancer patients participating in the intervention and patients receiving psychosocial care at usual. Results indicate that individuals diagnosed with cancer attending the CDGI present significant increases in Fighting Spirit and Avoidance, while reporting also reduced levels of Fatalism and Anxious Preoccupation. Initial indications suggest that the intervention may contribute to strengthening the relationship with the primary support person.

    Nanotechnology-based drug delivery was born as a chance for pharmaceutical weapons to be delivered in the body sites where drug action is required. Specifically, the incorporation of anti-cancer agents in nanodevices of 100-300 nm allows their delivery in tissues that have a fenestrated vasculature and a reduced lymphatic drainage. These two features are typical of neoplastic tissues and, therefore, allow the accumulation of nanostructured devices in tumours. An important issue of anti-cancer pharmacological strategies is the overcoming of anatomical barriers such as the bloodbrain- barrier (BBB) that protects brain from toxicological injuries but, at the same time, makes impossible for most of the pharmacological agents with anti-cancer activity to reach tumour cells placed in the brain and derived from either primary tumours or metastases. In fact, only highly lipophilic molecules can passively diffuse through BBB to reach central nervous system (CNS). Another possibility is to use nanotechnological approaches as powerful tools to across BBB, by both prolonging the plasma half-life of the drugs and crossing fenestrations of BBB damaged by brain metastases. Moreover, modifications of nanocarrier surface with specific endogenous or exogenous ligands can promote the crossing of intact BBB as in the case of primary brain tumours. This aim can be achieved through the binding of the nanodevices to carriers or receptors expressed by the endothelial cells of BBB and that can favour the internalization of the nanostructured devices delivering anti-cancer drugs. This review summarizes the most meaningful advances in the field of nanotechnologies for brain delivery of drugs.

    Full Text Available Background: Maternal and infant mortality rates and prevalence of under nutrition are high in the State Madhya Pradesh. Regular ante-natal check-ups (ANC, delivery by trained health personnel, delivery practices and optimal infant feeding practices are important to reduce maternal and infant mortality. Objectives: The aim was to assess antenatal care, delivery and infant feeding practices of mothers of <1-year-old children in Madhya Pradesh. Materials and Methods: This was community-based cross-sectional study carried out in the rural areas of Madhya Pradesh by adopting systematic random sampling procedure. Data were collected from 5324 mothers having <1-year-old children. Information on household (HH socioeconomic and demographic particulars was collected from the mothers. Bivariate and multivariate analysis was performed to study the association between dependent and independent variables. Results and Interpretations: About 36% mothers had undergone at least three ante-natal check-ups and 73% delivered either at government or private hospitals. Only 26% mothers initiated breastfeeding within 1-h of birth and 92% fed colostrum. Step-wise regression analysis showed that ante-natal care for <3 times was significantly (P < 0.01 higher among women with high parity (≥5, illiterate women, and among lower socioeconomic group,s while home delivery was higher among women with high parity (≥5 (odds ratio [OR]: 2.3, among Scheduled Caste and Tribe women (OR: 1.5, illiteracy of head of HH (OR: 2, and among lower socioeconomic groups (OR: 1.3.

    Triple negative breast cancer has an extremely poor prognosis when chemotherapy is no longer effective. To overcome drug resistance, novel drug delivery systems based on nanoparticles have had remarkable success. We produced a novel nanoparticle component 'MDC' from milk-derived colloid. In order to evaluate the anti-cancer effect of MDC, we conducted in vitro and in vivo experiments on cancer cell lines and a primary tumor derived breast xenograft. Doxorubicin (Dox) conjugated to MDC (MDC-Dox) showed higher cancer cell growth inhibition than MDC alone especially in cell lines with high EGFR expression. In a mouse melanoma model, MDC-Dox significantly suppressed tumor growth when compared with free Dox. Moreover, in a primary tumor derived breast xenograft, one of the mice treated with MDC-Dox showed partial regression, while mice treated with free Dox failed to show any suppression of tumor growth. We have shown that a novel nanoparticle compound made of simple milk-derived colloid has the capability for drug conjugation, and serves as a tumor-specific carrier of anti-cancer drugs. Further research on its safety and ability to carry various anti-cancer drugs into multiple drug-resistant primary breast models is warranted.

    Understanding and apprehension of the characteristics and circumstances in which mesenchymal stem cells (MSCs) affect and make alterations (enhance or reduce) to the growth of tumors and metastasis spread is pivotal, not only for reaching the possibility to employ MSCs as drug delivery systems, but also for making forward movement in the existing knowledge of involvement of major factors (tumor microenvironment, soluble signaling molecules, etc.) in the process of carcinogenesis. This capability is reliable because MSCs present a great basis for engineering and constructions of new systems to target cancers, intended to secrete therapeutic proteins in the tumor region, or for delivering of oncolytic viruses' directly at the tumor site (targeted chemotherapy with enzyme prodrug conversion or induction of tumor cell apoptosis). MSCs as a crucial segment of the tumor surroundings and their confirmed tumor tropism, are assumed to be an open gateway for the design of promising drug delivery systems. The presented paper reviews current publications in this fieldwork, searches out the most recent patents that were published after 2012 (WO2014066122, US20140017787, WO2015100268, US20150086515), and tries to present the current progress and future prospective on the design and development in anti-cancer drug delivery systems based on MSCs.

    Full Text Available Cloud services permit healthcare providers to ensure information handling and allow different service resources such as Software as a Service (SaaS, Platform as a Service (PaaS and Infrastructure as a Service (IaaS on the Internet, given that security and information proprietorship concerns are attended to. Health Care Providers (HCPs in Nigeria however, have been confronted with various issues because of their method of operations. Amongst the issues are ill-advised methods of data storage and unreliable nature of patient medical records. Apart from these challenges, trouble in accessing quality healthcare services, high cost of medical services, and wrong analysis and treatment methodology are not left out. Cloud Computing has relatively possessed the capacity to give proficient and reliable method for securing medical information and the need for data mining tools in this form of distributed system will go a long way in achieving the objective set out for this project. The aim of this research therefore is to implement a cloud-based architecture that is suitable to integrate Healthcare Delivery into the cloud to provide a productive mode of operation. The proposed architecture consists of four phases (4-Tier; a User Authentication and Access Control Engine (UAACE which prevents unauthorized access to patient medical records and also utilizes standard encryption/decoding techniques to ensure privacy of such records. The architecture likewise contains a Data Analysis and Pattern Prediction Unit (DAPPU which gives valuable data that guides decision making through standard Data mining procedures as well as Cloud Service Provider (CSP and Health Care Providers (HCPs. The architecture which has been implemented on CloudSim has proved to be efficient and reliable base on the results obtained when compared with previous work.

  6. Virtual reality for the palliative care of cancer.

    We have been developing a VR system to provide patients with emotional support and to encourage them to assume an active life against cancer, since patients with an active lifestyle survive longer than those with a passive lifestyle. A possible explanation for this latter fact is that psychological stimulation may also activate the endocrine system and the immune system. Both systems may be able to rapidly repair tissue damaged by cancer and change the characteristics of the cancer itself. Although microelectrical analysis and molecular and genetic analyses are rapidly solving the riddles of the relationship between the brain and thought, we think that our VR research for palliative medicine may also play an important role in this area with regard to the development of new tools for treatment and support. This notion is based on the hypothesis that the brain can reorganize itself to compensate for irrationality or inappropriateness through pharmacological adaptation and/or anatomical regeneration of synapses. Another reason why VR research in palliative medicine is useful is that VR techniques represent not only an enhanced human-machine interface, but also an enhanced human communication technology. VR technology may also be used to help patients accept their disease. The mental state of a patient in the terminal stage of cancer changes step by step from denial of cancer, hope for a new treatment for cancer, suspicion of medical treatment, uneasiness regarding their future life, irritation, depression, and acceptance or despair. We plan to develop a new type of counseling system in medical cyberspace to provide mental care. It can also be used for group therapy or humor therapy to reduce loneliness. In summary, we conclude that VR technology can be applied to palliative medicine (1) to support communication between the patient and others, (2) to provide psychological support to treat neurosis and help to stabilize the patient's mental state, and (3) to actually

    Full Text Available OBJECTIVE: Patient chances for cure and palliation for a variety of malignancies may be greatly affected by the care provided by a treating hospital. We sought to determine the effect of volume and teaching status on patient outcomes for five gynecologic malignancies: endometrial, cervical, ovarian and vulvar carcinoma and uterine sarcoma. METHODS: The Florida Cancer Data System dataset was queried for all patients undergoing treatment for gynecologic cancers from 1990-2000. RESULTS: Overall, 48,981 patients with gynecologic malignancies were identified. Endometrial tumors were the most common, representing 43.2% of the entire cohort, followed by ovarian cancer (30.9%, cervical cancer (20.8%, vulvar cancer (4.6%, and uterine sarcoma (0.5%. By univariate analysis, although patients treated at high volume centers (HVC were significantly younger, they benefited from an improved short-term (30-day and/or 90-day survival for cervical, ovarian and endometrial cancers. Multivariate analysis (MVA, however, failed to demonstrate significant survival benefit for gynecologic cancer patients treated at teaching facilities (TF or HVC. Significant prognostic factors at presentation by MVA were age over 65 (HR = 2.6, p<0.01, African-American race (HR = 1.36, p<0.01, and advanced stage (regional HR = 2.08, p<0.01; advanced HR = 3.82, p<0.01, respectively. Surgery and use of chemotherapy were each significantly associated with improved survival. CONCLUSION: No difference in patient survival was observed for any gynecologic malignancy based upon treating hospital teaching or volume status. Although instances of improved outcomes may occur, overall further regionalization would not appear to significantly improve patient survival.

    Ensuring the development and delivery of person-centred care in services providing respite care and short breaks for people with dementia and their carers has a number of challenges for health and social service providers. This article explores the role of organisational culture in barriers and facilitators to person-centred dementia care. As part of a mixed-methods study of respite care and short breaks for people with dementia and their carers, 49 telephone semi-structured interviews, two focus groups (N= 16) and five face-to-face in-depth interviews involving front-line staff and operational and strategic managers were completed in 2006-2007. Qualitative thematic analysis of transcripts identified five themes on aspects of organisational culture that are perceived to influence person-centred care: understandings of person-centred care, attitudes to service development, service priorities, valuing staff and solution-focused approaches. Views of person-centred care expressed by participants, although generally positive, highlight a range of understandings about person-centred care. Some organisations describe their service as being person-centred without the necessary cultural shift to make this a reality. Participants highlighted resource constraints and the knowledge, attitudes and personal qualities of staff as a barrier to implementing person-centred care. Leadership style, the way that managers' support and value staff and the management of risk were considered important influences. Person-centred dementia care is strongly advocated by professional opinion leaders and is prescribed in policy documents. This analysis suggests that person-centred dementia care is not strongly embedded in the organisational cultures of all local providers of respite-care and short-break services. Provider organisations should be encouraged further to develop a shared culture at all levels of the organisation to ensure person-centred dementia care.

    Full Text Available Background: Efforts have been made to measure integration in health care delivery, but few existing instruments have adopted a patient perspective, and none is sufficiently generic and brief for administration at scale. We sought to develop a brief and generic patient-reported measure of integration in health care delivery.Methods: Drawing on both existing conceptualisations of integrated care and research on patients’ perspectives, we chose to focus on four distinct domains of integration: information sharing,consistent advice, mutual respect and role clarity. We formulated candidate items and conducted cognitive interviews with end users to further develop and refine the items. We then pilot-tested the measure.Results: Four rounds of cognitive interviews were conducted (n = 14 and resulted in a four-item measure that was both relevant and understandable to end users. The pilot administration of the measure (n = 15 further confirmed the relevance and interpretability of items and demonstrated that the measure could be completed in less than one minute.Conclusions: This new measure, IntegRATE, represents a patient-reported measure of integration in health care delivery that is conducive to use in both routine performance monitoring and research. The psychometric properties of the measure will be assessed in the next stage of development.

    An audit was undertaken of people with a diagnosis of breast cancer who were referred to a community palliative care specialist nursing team over a 12-month period, to explore the reasons for referral to the service and the duration of involvement with the service. Breast cancer patients accounted for 10% of the total referrals to the specialist service, with symptom management (including pain control) and emotional support being the main reasons for referral. The majority of people referred with breast cancer had metastatic breast cancer (87%); interestingly, 13% had primary breast cancer. The mean duration of intervention was 3 months and 1 week. Referrals seemed to occur late in patients' disease trajectories, and total numbers were lower than might be expected. It may be concluded that there is scope for the specialist palliative care team to be a more integral part of care for patients with metastatic breast cancer.

    The objective of this study was to evaluate the biocompatibility of zirconium phosphate (ZrP) nanoplatelets (NPs), and their use in drug delivery. ZrP and doxorubicin-intercalated ZrP (DOX:ZrP) NPs were characterized by using X-Ray Powder Diffraction (XRPD), Thermogravimetric Analysis (TGA), Transmission Electron Micrography (TEM), Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Biocompatibility of ZrP NPs was evaluated in human embryonic kidney (HEK-293), breast cancer (MCF-7), metastatic breast cancer (MDA-MB-231), ovarian cancer (OVCAR-3), resistant cancer (NCI-RES/ADR) cells and mouse macrophage (RAW 264.7) cell lines. Hemocompatibility of ZrP NPs was evaluated with human red blood cells. Simulated body fluid (SBF) of pH 7.4 was used to determine the in vitro release of doxorubicin from DOX:ZrP NPs. Cellular uptake and in vitro cytotoxicity studies of DOX:ZrP NPs were determined in MDA-MB-231. The ZrP nanomaterial can be prepared in the 100-200 nm size range with a platelet-like shape. The ZrP NPs themselves are biocompatible, hemocompatible and showed no toxicity to the macrophage cells. ZrP NPs can intercalate high loads (35% w/w) of doxorubicin between their layers. The release of DOX was sustained for about 2 weeks. DOX:ZrP NPs showed higher cellular uptake and increased cytotoxicity than free DOX in MDA-MB-231 cells. ZrP NPs are highly biocompatible, can intercalate large amounts of drugs and sustain the release of drugs. ZrP NPs improved the cellular uptake and cytotoxicity of DOX to MDA-MB-231 cells. ZrP NPs are promising nanocarriers for drug delivery in cancer therapy.The objective of this study was to evaluate the biocompatibility of zirconium phosphate (ZrP) nanoplatelets (NPs), and their use in drug delivery.

    Targeted uptake of therapeutic nanoparticles in cell- or tissue-specific manner is an attractive technology since they can offer greater efficacy and reduce cytotoxicity on peripheral healthy tissues. In this study, AS1411 (AP), a DNA aptamer specifically binding to nucleolin that is overexpressed on the plasma membrane of breast cancer (BC) cells, was exploited as the targeting ligand of a nanoparticle-based drug delivery system. Vinorelbine (VRL) loaded PLGA-PEG nanoparticles (NP) were formulated by an emulsion/solvent evaporation method, and AP was conjugated to the particle surface using the EDC/NHS technique. The drug-loading efficiency and in vitro drug release studies were measured using HPLC. The resulting AP-NP/VRL formed spherical nanoparticles (AS1411-functionalized nanoparticles are potential carrier candidates for targeted drug delivery towards BC.

    Present work was focused on producing improved iron oxide nanoparticles for targeted drug delivery in breast cancer. Nanometric-sized iron oxide particles were synthesized by laser pyrolysis and were morphologically/structurally characterized. These new nanoparticles were compared with some commercial, chemically prepared iron oxide ones. Cytotoxicity and the anti-proliferation effects of nanoparticles were tested in vitro on the breast adenocarcinoma cell line MCF-7. Nanoparticles were further coated with the antracyclinic antibiotic Violamycine B1 and tested for the anti-tumor effect on MCF-7 cells. The nanoparticles produced by us seem more effective in vitro than the commercial ones, with respect to cellular uptake and VB1 delivery. Violamycine B1 bound on nanoparticles is as efficient as the free form, but is better delivered into tumor cells.

    In this paper, hyaluronic acid (HA) functionalized uniform mesoporous carbon spheres (UMCS) were synthesized for targeted enzyme responsive drug delivery using a facile electrostatic attraction strategy. This HA modification ensured stable drug encapsulation in mesoporous carbon nanoparticles in an extracellular environment while increasing colloidal stability, biocompatibility, cell-targeting ability, and controlled cargo release. The cellular uptake experiments of fluorescently labeled mesoporous carbon nanoparticles, with or without HA functionalization, demonstrated that HA-UMCS are able to specifically target cancer cells overexpressing CD44 receptors. Moreover, the cargo loaded doxorubicin (DOX) and verapamil (VER) exhibited a dual pH and hyaluronidase-1 responsive release in the tumor microenvironment. In addition, VER/DOX/HA-UMCS exhibited a superior therapeutic effect on an in vivo HCT-116 tumor in BALB/c nude mice. In summary, it is expected that HA-UMCS will offer a new method for targeted co-delivery of drugs to tumors overexpressing CD44 receptors.

    Nanoclay can be incorporated into emerging dual functional drug delivery systems (DDSs) to promote efficiency in drug delivery and reduce the toxicity of doxorubicin (DOX) used for thyroid cancer treatment. This paper reports the expansion of the basal spacing of kaolinite nanoclay was expanded from 0.72 nm to 0.85 nm, which could provide sufficiently spacious site for hosting doxorubicin molecules and controlling the diffusion rate. A targeted design for papillary thyroid cancer cells was achieved by introducing KI, which is consumed by the sodium-iodide symporter (NIS). As indicated by MTT assays, confocal laser scanning microscopy and bio-TEM observations, methoxy-intercalated kaolinite (KaolinMeOH) exhibited negligible cytotoxicity against papillary thyroid cancer cells. By contrast, DOX-KaolinMeOH showed dose-dependent therapeutic effects in vitro, and KI@DOX-KaolinMeOH was found to act as a powerful targeted therapeutic drug. Furthermore, active and passive targeting strategies played a role in the accumulation of the drug molecules, as verified by an in vivo bio-distribution analysis.

    We hypothesized that nanosuspensions could be promising for the delivery of the poorly water soluble anti-cancer multi-targeted kinase inhibitor, MTKi-327. Hence, the aims of this work were (i) to evaluate the MTKi-327 nanosuspension for parenteral and oral administrations and (ii) to compare this nanosuspension with other nanocarriers in terms of anti-cancer efficacy and pharmacokinetics. Therefore, four formulations of MTKi-327 were studied: (i) PEGylated PLGA-based nanoparticles, (ii) self-assembling PEG₇₅₀-p-(CL-co-TMC) polymeric micelles, (iii) nanosuspensions of MTKi-327; and (iv) Captisol solution (pH=3.5). All the nano-formulations presented a size below 200 nm. Injections of the highest possible dose of the three nano-formulations did not induce any side effects in mice. In contrast, the maximum tolerated dose of the control Captisol solution was 20-fold lower than its highest possible dose. The highest regrowth delay of A-431-tumor-bearing nude mice was obtained with MTKi-327 nanosuspension, administered intravenously, at a dose of 650 mg/kg. After intravenous and oral administration, the AUC₀₋∞ of MTKi-327 nanosuspension was 2.4-fold greater than that of the Captisol solution. Nanosuspension may be considered as an effective anti-cancer MTKi-327 delivery method due to (i) the higher MTKi-327 maximum tolerated dose, (ii) the possible intravenous injection of MTKi-327, (iii) its ability to enhance the administered dose and (iv) its higher efficacy.

    Purpose Radiation and chemotherapy are the most common course of treatment for B-cell lymphoma. Doxorubicin (DOX), gemcitabine (GEM), and vincristine (VCR) are the commonly used antilymphoma chemotherapeutic drugs. The aim of this study is to construct a novel drug delivery system for the combination delivery of the three drugs on lymphoma. Materials and methods DOX–GEM prodrug was synthesized. Novel nanostructured lipid carriers (NLCs) containing DOX–GEM prodrug and VCR were prepared and used to treat B-cell lymphoma through in vivo treatment to a lymph cancer animal model. The systemic toxicity of the nanomedicine was also evaluated during the treatment. Results DOX–GEM prodrug and VCR-loaded NLCs (DOX–GEM VCR NLCs) exhibited the highest antitumor effect in B-cell lymphoma cells and lymphoma animal xenografts when compared with the single drug-loaded NLCs and the drug solutions. Conclusion It could be concluded that the highest antitumor effect can be achieved by the system due to the stable drug-loading capacity, attractive anticancer therapeutic effects, and reduced toxicities in human Burkitt’s lymphoma cell line and mice-bearing cancer model. The resulting DOX–GEM VCR NLCs could be an efficient antilymph cancer agent and could be developed further for the treatment of other tumors.

    By enabling nanoparticle-based drug delivery system to actively target cancer cells with high selectivity, active targeted molecules have attracted great attention in the application of nanoparticles for anticancer drug delivery. However, the clinical application of most active targeted molecules in breast cancer therapy is limited, due to the low expression of their receptors in breast tumors or coexpression in the normal and tumor breast tissues. Here, a neuropeptide Y Y1 receptors ligand PNBL-NPY, as a novel targeted molecule, is conjugated with anticancer drug doxorubicin encapsulating albumin nanoparticles to investigate the effect of Y1 receptors on the delivery of drug-loaded nanoparticles to breast cancer cells and its potential for breast cancer therapy. The PNBL-NPY can actively recognize and bind to the Y1 receptors that are significantly overexpressed on the surface of the breast cancer cells, and the drug-loaded nanoparticles are delivered directly into the cancer cells through internalization. This system is highly selective and able to distinguish the breast cancer cells from the normal cells, due to normal breast cells that express Y2 receptors only. It is anticipated that this study may provide a guidance in the development of Y1 receptor-based nanoparticulate drug delivery system for a safer and more efficient breast cancer therapy.

    Taxol(®) remained as the mainstay therapeutic agent in the treatment of ovarian cancer, however recurrence rate is still high. Cancer stem cells (CSCs) represent a subset of cells in the bulk of tumors and play a central role in inducing drug resistance and recurrence. Furthermore, cancer metabolism has been an area under intensive investigation, since accumulating evidence has shown that CSCs and cancer metabolism are closely linked, an effect named as metabolic reprogramming. In this work, we aimed to investigate the impacts of a novel liposome-encapsulated paclitaxel (Nano-Taxol) on the stemness phenotype and metabolic reprogramming. A paclitaxel-resistant cell line (TR) was established at first. Tumor growth was induced in the mice peritoneal cavity by inoculation of TR cells. A 2x2 factorial experiment was designed to test the therapeutic efficacy in which factor 1 represented the comparison of drugs (Taxol(®) versus Nano-Taxol), while factor 2 represented the delivery route (intravenous versus intraperitoneal delivery). In this work, we found that intraperitoneal delivery of Nano-Taxol redirects metabolic reprogramming, from glycolysis to oxidative phosphorylation, and effectively suppresses cancer stem cells. Also, intraperitoneal delivery of Nano-Taxol led to a significantly better control of tumor growth compared with intravenous delivery of Taxol(®) (current standard treatment). This translational research may serve as a novel pathway for the drug development of nanomedicine. In the future, this treatment modality may be extended to treat several relevant cancers that have been proved to be suitable for the loco-regional delivery of therapeutic agents, including colon cancer, gastric cancer, and pancreatic cancer.

    Background The demonstrated benefit of integrating palliative care (PC) into cancer treatment has triggered an increased need for PC services. The trajectory of integrating PC in comprehensive cancer centers, particularly pediatric centers, is unknown. We describe our eight-year experience of initiating and establishing PC with the Quality of Life Service (QoLS) at St. Jude Children’s Research Hospital. Patients and Methods We retrospectively reviewed records of patients seen by the QoLS (n= 615) from March 2007 to December 2014. Variables analyzed for each year, using descriptive statistics, included diagnostic groups, QoLS encounters, goals of care, duration of survival, and location of death. Results Total QoLS patient encounters increased from 58 (2007) to 1297 (2014), new consults increased from 17 (2007) to 115 (2014), and mean encounters per patient increased from 5.06 (2007) to 16.11 (2014). Goal of care at initial consultation shifted from primarily comfort to an increasing goal of cure. The median number of days from initial consult to death increased from 52 days (2008) to 223 days (2014). A trend toward increased outpatient location of death was noted with 42% outpatient deaths in 2007 increasing to a majority in each subsequent year (range 51–74%). Hospital-wide, patients receiving PC services before death increased from approximately 50% to nearly 100%. Conclusions Since its inception, the QoLS experienced a dramatic rise in referrals and encounters per patient, utilization by all clinical services, a trend toward earlier consultation and longer term follow-up, increasing outpatient location of death, and near-universal PC involvement at the end-of-life. The successful integration of PC in a comprehensive cancer center, and resulting potential for improved care provision over time, can serve as a model for other programs on a broad scale.

    A nanoparticle-conjugated cancer drug provides a novel strategy for cancer therapy. In this study, we manipulated nanodiamond (ND), a carbon nanomaterial, to covalently link paclitaxel for cancer drug delivery and therapy. Paclitaxel was bound to the surface of 3-5 nm sized ND through a succession of chemical modifications. The ND-paclitaxel conjugation was measured by atomic force microscope and nuclear magnetic resonance spectroscopy, and confirmed with infrared spectroscopy by the detection of deuterated paclitaxel. Treatment with 0.1-50 {mu}g ml{sup -1} ND-paclitaxel for 48 h significantly reduced the cell viability in the A549 human lung carcinoma cells. ND-paclitaxel induced both mitotic arrest and apoptosis in A549 cells. However, ND alone or denatured ND-paclitaxel (after treatment with strong alkaline solution, 1 M NaOH) did not induce the damage effects on A549 cells. ND-paclitaxel was taken into lung cancer cells in a concentration-dependent manner using flow cytometer analysis. The ND-paclitaxel particles were located in the microtubules and cytoplasm of A549 cells observed by confocal microscopy. Furthermore, ND-paclitaxel markedly blocked the tumor growth and formation of lung cancer cells in xenograft SCID mice. Together, we provide a functional covalent conjugation of ND-paclitaxel, which can be delivered into lung carcinoma cells and preserves the anticancer activities on the induction of mitotic blockage, apoptosis and anti-tumorigenesis.

    A magnetic targeted functionalized graphene oxide (GO) complex is constituted as a nanocarrier for targeted delivery and pH-responsive controlled release of chemotherapy drugs to cancer cells. Magnetic graphene oxide (mGO) was prepared by chemical co-precipitation of Fe3O4 magnetic nanoparticles on GO nano-platelets. The mGO was successively modified by chitosan and mPEG-NHS through covalent bindings to synthesize mGOC-PEG. The polyethylene glycol (PEG) moiety is expected to prolong the circulation time of mGO by reducing the reticuloendothelial system clearance. Irinotecan (CPT-11) or doxorubicin (DOX) was loaded to mGOC-PEG through π-π stacking interactions for magnetic targeted delivery of the cancer chemotherapy drug. The best values of loading efficiency and loading content of CPT-11 were 54% and 2.7% respectively; whereas for DOX, they were 65% and 393% The pH-dependent drug release profile was further experimented at different pHs, in which 60% of DOX was released at pH 5.4 and 10% was released at pH 7.4. In contrast, 90% CPT-11 was released at pH 5.4 and 70% at pH 7.4. Based on the drug loading and release characteristics, mGOC-PEG/DOX was further chosen for in vitro cytotoxicity tests against U87 human glioblastoma cell line. The IC50 value of mGOC-PEG/DOX was found to be similar to that of free DOX but was reduced dramatically when subject to magnetic targeting. It is concluded that with the high drug loading and pH-dependent drug release properties, mGOC-PEG will be a promising drug carrier for targeted delivery of chemotherapy drugs in cancer therapy.

    Full Text Available This paper presents architecture for health care data warehouse specific to cancer diseases which could be used by executive managers, doctors, physicians and other health professionals to support the healthcare process. The data today existing in multi sources with different formats makes it necessary to have some techniques for data integration. Executive managers need access to Information so that decision makers can react in real time to changing needs. Information is one of the most factors to an organization success that executive managers or physicians would need to base their decisions on, during decisionmaking. A health care data warehouse is therefore necessary to integrate the different data sources into a central data repository and analysis this data.

    Purpose - The purpose of this paper is to investigate healthcare customer complaints concerning interpersonal matters in cancer care. Design/methodology/approach - Complaints from cancer patients and their relatives (n=116) that dealt with interpersonal matters registered between 2009 and 2011 at four local Patients' Advisory Committees in Western Sweden were sampled and analyzed using qualitative content analysis. Findings - Complaints concerned lack of information and consideration from healthcare providers. Lack of empathy and civility also caused dissatisfaction, the latter particularly for women. Relatives complained that they did not feel included in the care process or were not offered proper support. Most complaints by relatives were filed by a female relative and concerned a male patient. Research limitations/implications - Information about patient demographics other than gender could not be investigated due to database limitations. Hence, factors such as age, country of birth, and geographical residence were not included for analysis. In addition, neither the type nor stage of cancer among the sampled patients was able to be addressed. Practical implications - Patient complaints should not only be viewed as a post-consumption judgment, but also as a service interaction activity. This may require healthcare providers to enhance their interpersonal skills, allowing patients and relatives to provide feedback during service interaction to satisfactorily address dissatisfaction. Visualizing gender disparities may help healthcare providers prevent stereotypical encounters. In addition, the provider should be invited to participate in the customer's value creating network, which may also include knowledge and skills from other sources, such as relatives. Originality/value - Value co-creation offers a different view on patient complaints. Incorporating social construction into value co-creation may reveal socially constructed disparities.

    Full Text Available Background: Maternal mortality remains a leading cause of death among women of reproductive age. While Nigeria has only two percent of the global population, it contributes 10% to the global maternal mortality burden. Antenatal care (ANC reduces the incidence of maternal mortality. However, financial capability affects access to antenatal care. Thus, the rural poor are at a higher risk of maternal mortality. Materials and Methods: A cross-sectional descriptive study involving 135 women (pregnant women and those who are 6 weeks postpartum. Structured interviewer-administered questionnaires were used for data collection. Data analysis was carried out using statistical package for social sciences software (version 17. Results: The average amount spent on booking and initial laboratory investigations were N77 (half a dollar and N316 ($2, respectively. Per ANC visit, average amount spent on drugs and transportation were N229 ($1.5 and N139 ($0.9 respectively. For delivery, the average amount spent was N1500 ($9.6. On an average, ANC plus delivery cost about N3,365.00 ($22. There was a statistically significant association between husband′s income and ANC attendance (X 2 = 2.451, df = 2, P = 0.048. Conclusion: Cost of Antenatal care and delivery services were not catastrophic but were a barrier to accessing antenatal care and facility-based delivery services in the study area. ANC attendance was associated with the income of household heads. Pro-poor policies and actions are needed to address this problem, as it will go a long way in reducing maternal mortality in this part of the country.

    Human Papillomaviruses (HPV) are a diverse group of small non-enveloped DNA viruses. Some HPVs are classified as low-risk as they are very rarely associated with neoplasia or cancer in the general population, and cause lenient warts. Other HPVs are considered as high-risk types because they are responsible for several important human cancers, including cervical cancer, a large proportion of other anogenital cancers, and a growing number of head and neck cancers. Transmission of HPV occurs primarily by skin-to-skin contact. The risk of contracting genital HPV infection and cervical cancer is influenced by sexual activity. Currently two prophylactic HPV vaccines, Gardasil® (Merck, USA) and Cervarix® (GlaxoSmithKline, UK), are available and recommended for mass immunization of adolescents. However, these vaccines have limitations as they are expensive and require cold chain storage and trained personnel to administer them by injection. The use of nano or micro particulate vaccines could address most of these limitations as they are stable at room temperature, inexpensive to produce and distribute to resource poor regions, and can be administered orally without the need for adjuvants in the formulation. Also it is possible to increase the efficiency of these particulate vaccines by decorating the surface of the nano or micro particulates with suitable ligands for targeted delivery. Oral vaccines, which can be delivered using particulate formulations, have the added potential to stimulate mucosa-associated lymphoid tissue located in the digestive tract and the gut-associated lymphoid tissue, both of which are important for the induction of effective mucosal response against many viruses. In addition, oral vaccines provide the opportunity to reduce production and administration costs and are very patient compliant. This review elaborately discusses different strategies that can be pursued to develop a nano or micro particulate oral vaccine for HPV induced cancers and

    A number of anti-cancer drugs have their targets localized to particular intracellular compartments. These drugs reach the targets mainly through diffusion, dependent on biophysical and biochemical forces that allow cell penetration. This means that both cancer cells and normal cells will be subjected to such diffusion; hence many of these drugs, like chemotherapeutics, are potentially toxic and the concentration achieved at the site of their action is often suboptimal. The same relates to radiation that indiscriminately affects normal and diseased cells. However, nature-designed systems enable compounds present in the extracellular environment to end up inside the cell and even travel to more specific intracellular compartments. For example, viruses and bacterial toxins can more or less specifically recognize eukaryotic cells, enter these cells, and direct some protein portions to designated intracellular areas. These phenomena have led to creative thinking, such as employing viruses or bacterial toxins for cargo delivery to cells and, more specifically, to cancer cells. Proteins can be genetically engineered in order to not only mimic what viruses and bacterial toxins can do, but also to add new functions, extending or changing the intracellular routes. It is possible to make conjugates or, more preferably, single-chain proteins that recognize cancer cells and deliver cargo inside the cells, even to the desired subcellular compartment. These findings offer new opportunities to deliver drugs/labels only to cancer cells and only to their site of action within the cells. The development of such dual-specificity vectors for targeting cancer cells is an attractive and potentially safer and more efficacious way of delivering drugs. We provide examples of this approach for delivering brain cancer therapeutics, using a specific biomarker on glioblastoma tumor cells.

    Since the 1970s breast cancer services have witnessed considerable changes in the management of patients. One significant change was the introduction of specialist core personnel, including the breast care nurse (BCN). The role of the BCN has been gaining credence rapidly in the British NHS and this service is perhaps the paradigm of care for other services. With the lack of specific evidence of the role of specialist nurses in the breast care team, the current study aims to explore this area by in-depth interviews with core team members, and observations of 16 multi-disciplinary teams in England. The study explores the following themes: Nurses' unique informal management leadership role in ensuring the co-ordination, communication and planning of the team work; nurses' innovatory role in making the bureaucracy respond to patients and their relatives needs; nurses supportive role in the provision of expert advice and guidance to other members of the team; nurses confidence and humour in well-performing teams; and the limitations of the professional role of the breast cancer nurse. This study indicates that there is evidence that the BCN is practicing at an advanced level of practice. However, there is a severe lack of evidence-based description of that advanced practice. Cancer nurses including the BCNs should develop and participate in programmes of research in line with cancer legislation in order to build an evidence base that ultimately supports their unique role.

    2010-10-01

    Full Text Available Abstract Background High quality maternal health care is an important tool to reduce maternal and neonatal mortality. Services offered should be evidence based and adapted to the local setting. This qualitative descriptive study explored the perspectives and experiences of midwives, assistant physicians and medical doctors on the content and quality of maternal health care in rural Vietnam. Method The study was performed in a rural district in northern Vietnam. Four focus group discussions with health care professionals at primary health care level were conducted. The data was analysed using qualitative manifest and latent content analysis. Result Two main themes emerged: "Contextual conditions for maternal health care" and "Balancing between possibilities and constraints". Contextual conditions influenced both pregnant women's use of maternal health care and health care professionals' performance. The study participants stated that women's uses of maternal health care were influenced by economical constraints and cultural norms that impeded their autonomy in relation to childbearing. Structural constraints within the health care system included inadequate financing of the primary health care, resulting in lack of human resources, professional re-training and adequate equipment. Conclusion Contextual conditions strongly influenced the performance and interaction between pregnant women and health care professionals within antenatal care and delivery care in a rural district of Vietnam. Although Vietnam is performing comparatively well in terms of low maternal and child mortality figures, this study revealed midwives' and other health care professionals' perceived difficulties in their daily work. It seemed maternal health care was under-resourced in terms of staff, equipment and continuing education activities. The cultural setting in Vietnam constituting a strong patriarchal society and prevailing Confucian norms limits women's autonomy and

Venuta, Viale Europa 88100 Catanzaro, Italy *These authors contributed equally to this workAbstract: During recent decades there have been remarkable advances and profound changes in cancer therapy. Many therapeutic strategies learned at the bench, including monoclonal antibodies and small molecule inhibitors, have been used at the bedside, leading to important successes. One of the most important advances in biology has been the discovery that small interfering RNA (siRNA is able to regulate the expression of genes, by a phenomenon known as RNA interference (RNAi. RNAi is one of the most rapidly growing fields of research in biology and therapeutics. Much research effort has gone into the application of this new discovery in the treatment of various diseases, including cancer. However, even though these molecules may have potential and strong utility, some limitations make their clinical application difficult, including delivery problems, side effects due to off-target actions, disturbance of physiological functions of the cellular machinery involved in gene silencing, and induction of the innate immune response. Many researchers have attempted to overcome these limitations and to improve the safety of potential RNAi-based therapeutics. Nanoparticles, which are nanostructured entities with tunable size, shape, and surface, as well as biological behavior, provide an ideal opportunity to modify current

    Alliance Against Cancer (ACC) was established in Rome in 2002 as a consortium of six Italian comprehensive cancer centers (Founders). The aims of ACC were to promote a network among Italian oncologic institutions in order to develop specific, advanced projects in clinical and translational research. During the following years, many additional full and associate members joined ACC, that presently includes the National Institute of Health, 17 research-oriented hospitals, scientific and patient organizations. Furthermore, in the last three years ACC underwent a reorganization process that redesigned the structure, governance and major activities. The present goal of ACC is to achieve high standards of care across Italy, to implement and harmonize principles of modern personalized and precision medicine, by developing cost effective processes and to provide tailored information to cancer patients. We herein summarize some of the major initiatives that ACC is currently developing to reach its goal, including tumor genetic screening programs, establishment of clinical trial programs for cancer patients treated in Italian cancer centers, facilitate their access to innovative drugs under development, improve quality through an European accreditation process (European Organization of Cancer Institutes), and develop international partnerships. In conclusion, ACC is a growing organization, trying to respond to the need of networking in Italy and may contribute significantly to improve the way we face cancer in Europe.

    Full Text Available Abstract Background Antenatal Care (ANC during pregnancy can play an important role in the uptake of evidence-based services vital to the health of women and their infants. Studies report positive effects of ANC on use of facility-based delivery and perinatal mortality. However, most existing studies are limited to cross-sectional surveys with long recall periods, and generally do not include population-based samples. Methods This study was conducted within the Health and Demographic Surveillance System (HDSS of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b in Matlab, Bangladesh. The HDSS area is divided into an icddr,b service area (SA where women and children receive care from icddr,b health facilities, and a government SA where people receive care from government facilities. In 2007, a new Maternal, Neonatal, and Child Health (MNCH program was initiated in the icddr,b SA that strengthened the ongoing maternal and child health services including ANC. We estimated the association of ANC with facility delivery and perinatal mortality using prospectively collected data from 2005 to 2009. Using a before-after study design, we also determined the role of ANC services on reduction of perinatal mortality between the periods before (2005 – 2006 and after (2008–2009 implementation of the MNCH program. Results Antenatal care visits were associated with increased facility-based delivery in the icddr,b and government SAs. In the icddr,b SA, the adjusted odds of perinatal mortality was about 2-times higher (odds ratio (OR 1.91; 95% confidence intervals (CI: 1.50, 2.42 among women who received ≤1 ANC compared to women who received ≥3 ANC visits. No such association was observed in the government SA.

    Successful gene therapy largely depends on the selective introduction of therapeutic genes into the appropriate target cancer cells. One of the most effective and promising approaches for targeting tumor tissue during gene delivery is the use of viral vectors, which allow for high efficiency gene delivery. However, the use of viral vectors is not without risks and safety concerns, such as toxicities, a host immune response towards the viral antigens or potential viral recombination into the host's chromosome; these risks limit the clinical application of viral vectors. The Sleeping Beauty (SB) transposon-based system is an attractive, non-viral alternative to viral delivery systems. SB may be less immunogenic than the viral vector system due to its lack of viral sequences. The SB-based gene delivery system can stably integrate into the host cell genome to produce the therapeutic gene product over the lifetime of a cell. However, when compared to viral vectors, the non-viral SB-based gene delivery system still has limited therapeutic efficacy due to the lack of long-lasting gene expression potential and tumor cell specific gene transfer ability. These limitations could be overcome by modifying the SB system through the introduction of the hTERT promoter and the SV40 enhancer. In this study, a modified SB delivery system, under control of the hTERT promoter in conjunction with the SV40 enhancer, was able to successfully transfer the suicide gene (HSV-TK) into multiple types of cancer cells. The modified SB transfected cancer cells exhibited a significantly increased cancer cell specific death rate. These data suggest that our modified SB-based gene delivery system can be used as a safe and efficient tool for cancer cell specific therapeutic gene transfer and stable long-term expression.

    Nano-sized self-assemblies based on amphiphilic iodinated hyaluronic acid (HA) were developed for use in cancer diagnosis and therapy. 2,3,5-Triiodobenzoic acid (TIBA) was conjugated to an HA oligomer as a computed tomography (CT) imaging modality and a hydrophobic residue. Nanoassembly based on HA-TIBA was fabricated for tumor-targeted delivery of doxorubicin (DOX). Cellular uptake of DOX from nanoassembly, compared to a DOX solution group, was enhanced via an HA-CD44 receptor interaction, and subsequently, the in vitro antitumor efficacy of DOX-loaded nanoassembly was improved in SCC7 (CD44 receptor positive squamous cell carcinoma) cells. Cy5.5, a near-infrared fluorescence (NIRF) dye, was attached to the HA-TIBA conjugate and the in vivo tumor targetability of HA-TIBA nanoassembly, which is based on the interaction between HA and CD44 receptor, was demonstrated in a NIRF imaging study using an SCC7 tumor-xenografted mouse model. Tumor targeting and cancer diagnosis with HA-TIBA nanoassembly were verified in a CT imaging study using the SCC7 tumor-xenografted mouse model. In addition to efficient cancer diagnosis using NIRF and CT imaging modalities, improved antitumor efficacies were shown. HA and TIBA can be used to produce HA-TIBA nanoassembly that may be a promising theranostic nanosystem for cancers that express the CD44 receptor.

    A novel HER2-targeted carrier was developed using bionanocapsules (BNCs). Bionanocapsules (BNCs) are 100-nm hollow nanoparticles composed of the L-protein of hepatitis B virus surface antigen. An affibody of HER2 was genetically displayed on the BNC surface (Z(HER2)-BNC). For the investigation of binding affinity, Z(HER2)-BNC was incubated with the cancer cell lines SK-BR-3 (HER2 positive), and MDA-MB-231 (HER2 negative). For analysis of HER2 targeting specificity, Z(HER2)-BNC or Z(WT)-BNC (without affibody) was incubated with both SK-BR-3 and MDA-MB-231 cells by time lapse and concentration. For the delivery of encapsulated molecules (calcein), fluorescence of Z(HER2)-BNC mixed with liposomes was also compared with that of Z(WT)-BNC and nude liposomes by incubation with SK-BR-3 cells. As a result, Z(HER2)-BNC-liposome complex demonstrated the delivery to HER2-expressing cells (SK-BR-3) with a high degree of specificity. This indicates that genetically engineered BNCs are promising carrier for cancer treatment.

    The aim of this study was to synthesize green chemistry based gold nanoparticles using liver specific biopolymer and to develop a liver cancer targeted drug delivery system with enhanced efficacy and minimal side effects. Pullulan stabilized gold nanoparticles (PAuNPs) were coupled with 5-Fluorouracil (5-Fu) and folic acid (Fa) which could be used as a tool for targeted drug delivery and imaging of cancer. The toxicity of 5-Fu, 5-Fu adsorbed gold nanoparticles (5-Fu@AuNPs), Fa-coupled 5-Fu adsorbed gold nanoparticles (5-Fu@AuNPs-Fa), was studied using zebrafish embryo as an in vivo model. The in vitro cytotoxicity of free 5-Fu, 5-Fu@AuNPs, 5-Fu@AuNPs-Fa against HepG2 cells was studied and found that the amount of 5-Fu required to achieve 50% of growth of inhibition (Ic50) was much lower in 5-Fu@AuNP-Fa than in free 5-Fu, 5-Fu@AuNPs. The in vivo biodistribution of PAuNPs showed that higher amount of gold had been accumulated in liver (54.42±5.96 μg) than in other organs.

    Gene therapy offers a bright future for the treatment of cancers. One of the research highlights focuses on smart gene delivery vectors with good biocompatibility and tumor-targeting ability. Here, a novel gene vector self-assembled through avidin-biotin interaction with optimized targeting functionality, biotinylated tumor-targeting peptide/avidin/biotinylated cell-penetrating peptide (TAC), was designed and prepared to mediate the in vitro and in vivo delivery of p53 gene. TAC exhibited efficient DNA-binding ability and low cytotoxicity. In in vitro transfection assay, TAC/p53 complexes showed higher transfection efficiency and expression amount of p53 protein in MCF-7 cells as compared with 293T and HeLa cells, primarily due to the specific recognition between tumor-targeting peptides and receptors on MCF-7 cells. Additionally, by in situ administration of TAC/p53 complexes into tumor-bearing mice, the expression of p53 gene was obviously upregulated in tumor cells, and the tumor growth was significantly suppressed. This study provides an alternative and unique strategy to assemble functionalized peptides, and the novel self-assembled vector TAC developed is a promising gene vector for cancer therapy.

    Abstract Background: Early patient-physician care planning discussions may influence the intensity of end-of-life (EOL) care received by veterans with advanced cancer. Objective: The study objective was to evaluate the association between medical record documentation of patient-physician care planning discussions and intensity of EOL care among veterans with advanced cancer. Methods: This was a retrospective cohort study. Subjects were 665 veteran decedents diagnosed with stage IV colorectal, lung, or pancreatic cancer in 2008, and followed till death or the end of the study period in 2011. We estimated the effect of patient-physician care planning discussions documented within one month of metastatic diagnosis on the intensity of EOL care measured by receipt of acute care, intensive interventions, chemotherapy, and hospice care, using multivariate logistic regression models. Results: Veterans in our study were predominantly male (97.1%), white (74.7%), with an average age at diagnosis of 66.4 years. Approximately 31% received some acute care, 9.3% received some intensive intervention, and 6.5% had a new chemotherapy regimen initiated in the last month of life. Approximately 41% of decedents received no hospice or were admitted within three days of death. Almost half (46.8%) had documentation of a care planning discussion within the first month after diagnosis and those who did were significantly less likely to receive acute care at EOL (OR: 0.67; p=0.025). Documented discussions were not significantly associated with intensive interventions, chemotherapy, or hospice care. Conclusion: Early care planning discussions are associated with lower rates of acute care use at the EOL in a system with already low rates of intensive EOL care. PMID:26186553

    Older adult cancer survivors currently account for almost 60% of all cancer survivors. The number of older cancer survivors will continue to increase as the population ages and as patients' live longer after a cancer diagnosis. As part of cancer center accreditation, the American College of Surgeons Commission on Cancer® (CoC) has placed great importance on survivorship care planning. While the CoC has set standards for general survivorship care, there is sparse evidence on how to best care for older adult cancer survivors. Concern exists among the medical community that survivorship care plans could increase paperwork without improving outcomes. Given the diverse and unique needs of older adult cancer survivors, the inter-professional team provides a structure and process for survivorship care built around the particular needs of older adults. The Cancer and Aging Research Group (CARG), in partnership with the NIA/NCI, held a U13 conference in May 2015 in part to discuss survivorship care for older adults with cancer. This report discusses four themes that emerged from one section of the conference: (1) survivorship care is a process that continually evolves to meet the needs of older adults; (2) older adult cancer survivors have unique needs and care plans should be tailored to meet these needs; (3) the inter-professional team is ideally suited to structure survivorship care of older adults; (4) patient advocacy must be encouraged throughout the cancer care continuum. As evidence based survivorship practices develop, the unique needs of older adults need to be given substantial attention.

    Integrin αvβ3 receptor is expressed on several types of cancer cells, including pancreatic cancer cells, and plays an important role in tumor growth and metastasis. The ability to target the integrin αvβ3 receptor on cancer cells increases the efficacy of targeted therapy and reduces the side effects. The aim of this study is to develop a novel arginine-glycine-aspartic acid (RGD) peptide -conjugated albumin nanoparticle to enhance the intracellular uptake of anticancer drug into the pancreatic cancer cells through receptor-mediated endocytosis. In the cellular uptake studies, the fluorescent signal of RGD-conjugated BSANPs in BxPC3 cells was higher than that of BSANPs without RGD conjugation as determined by fluorescence spectrophotometer. We also found that BSANPs bound to BxPC3 cells in a time- and concentration-dependent manner. The uptake of RGD-conjugated BSANPs by pancreatic cancer cells was inhibited by an excess amount of free RGD peptide, indicating that the binding and/or uptake were mediated by the αvβ3 receptor. Furthermore, the nanoparticles were found to be located close to the nuclei by using laser scanning confocal microscopy. Besides, no significant in vitro cytotoxicity was observed as measured with MTT assay. Both in vitro and in vivo antitumor efficacy was improved by targeting gemcitabine-loaded nanoparticles to BxPC-3 cells using RGD peptides. Therefore, the RGD-conjugated BSANPs hold great potential as an effective drug delivery system to deliver therapeutic agents to pancreatic cancer.

    Breast cancer is the most common cancer among Latinas. This study examined social, cultural, and health care system factors that impact the quality of life and survivorship experiences of Latina immigrant breast cancer survivors. We interviewed Latina breast cancer survivors (n = 19) and, based on the interview findings, conducted two focus groups (n = 9). Research staff translated transcripts from Spanish into English. Two trained raters reviewed the content and identified themes. Thematic content analysis was used to categorize and organize data. Participants were largely monolingual in Spanish, predominantly from Central and South America and most (68%) had lived in the U.S. for ten or more years. All women were diagnosed and treated in the U.S. and were an average of 3.1 years from diagnosis. Women's survivorship experiences appeared to be shaped by cultural beliefs and experiences as immigrants such as secrecy/shame about a breast cancer diagnosis, feelings of isolation, importance of family support (familism), challenges with developing social relationships in the U.S. (less personalismo), and, for some, their partner's difficulty with showing emotional support (machismo). Navigating the U.S. medical system and language barriers were additional challenges in the participants' health care interactions. Latina breast cancer survivors adhere to certain cultural values and face unique issues as immigrants, potentially influencing overall quality of life and doctor-patient communication. Efforts to improve Latina immigrant breast cancer survivors' quality of life could include increased assessment of psychosocial functioning and referral to social support services, culturally sensitive navigation programs, and consistent use of appropriately trained interpreters.

    The particle shape of the drug delivery systems had a strong impact on their in vitro and in vivo performance, but there was limited availability of techniques to produce the specific shaped drug carriers. In this article, the novel methotrexate (MTX) decorated MPEG-PLA nanobacillus (MPEG-PLA-MTX NB) was prepared by the self-assembly technique followed by the extrusion through SPG membrane with high N2 pressure for targeted drug delivery, in which Janus-like MTX was not only used as a specific anticancer drug but could also be served as a tumor-targeting ligand. The MPEG-PLA-MTX NBs demonstrated much higher in vitro and in vivo targeting efficiency compared to the MPEG-PLA-MTX nanospheres (MPEG-PLA-MTX NSs) and MPEG-PLA nanospheres (MPEG-PLA NSs). In addition, the MPEG-PLA-MTX NBs also displayed much more excellent in vitro and in vivo antitumor activity than the MPEG-PLA-MTX NSs and free MTX injection. To our knowledge, this work provided the first example of the integration of the shape design (which mediated an early phase tumor accumulation and a late-phase cell internalization) and Janus-faced function (which mediated an early phase active targeting effect and a late-phase anticancer effect) on the basis of nanoscaled drug delivery systems. The highly convergent and cooperative drug delivery strategy opens the door to more drug delivery systems with new shapes and functions for cancer therapy.

    In an effort to improve nutrition care in a small community hospital with one registered dietitian (R.D.), a system using a nutrition care profile (NCP) and a certified dietetic assistant (C.D.A.) was developed. The NCP includes criteria recognized in the literature or through clinical experience to be indicators of nutrition care needs. The profile is completed by the C.D.A. and reviewed by the R.D., who determines priorities for the patient's nutrition care needs. The NCP has proved to be an effective and efficient tool for prioritizing and systematizing follow-up of nutrition care needs. Indeed, because the NCP form is itself so effective as a follow-up tool for dietary records, the R.D. has found she must make a conscious effort to document nutrition care in the medical record.

    Advances in early detection, prevention, and treatment have resulted in consistently falling cancer death rates in the United States. In parallel with these advances have come significant increases in the cost of cancer care. It is well established that the cost of health care (including cancer care) in the United States is growing more rapidly than the overall economy. In part, this is a result of the prices and rapid uptake of new agents and other technologies, including advances in imaging and therapeutic radiology. Conventional understanding suggests that high prices may reflect the costs and risks associated with the development, production, and marketing of new drugs and technologies, many of which are valued highly by physicians, patients, and payers. The increasing cost of cancer care impacts many stakeholders who play a role in a complex health care system. Our patients are the most vulnerable because they often experience uneven insurance coverage, leading to financial strain or even ruin. Other key groups include pharmaceutical manufacturers that pass along research, development, and marketing costs to the consumer; providers of cancer care who dispense increasingly expensive drugs and technologies; and the insurance industry, which ultimately passes costs to consumers. Increasingly, the economic burden of health care in general, and high-quality cancer care in particular, will be less and less affordable for an increasing number of Americans unless steps are taken to curb current trends. The American Society of Clinical Oncology (ASCO) is committed to improving cancer prevention, diagnosis, and treatment and eliminating disparities in cancer care through support of evidence-based and cost-effective practices. To address this goal, ASCO established a Cost of Care Task Force, which has developed this Guidance Statement on the Cost of Cancer Care. This Guidance Statement provides a concise overview of the economic issues facing stakeholders in the cancer

    Illness is constituted by subjective experiences of symptoms and their psychosocial consequences. Illness perceptions concern people's lay beliefs about understandings and interpretation of a disease and expectations as to disease outcome. Our knowledge about illness perceptions and coping in relation to the cancer care context among persons with colorectal cancer (CRC) and their partners is incomplete. The aim of the present study was to explore illness perceptions in relation to contemporary cancer care settings among CRC survivors and partners. The present research focused on illness rather than disease, implying that personal experiences are central to the methodology. The grounded theory method used is that presented by Kathy Charmaz. The present results explore illness perceptions in the early recovery phase after being diagnosed and treated for cancer in a contemporary cancer care setting. The core category outlook on the cancer diagnosis when quickly informed, treated, and discharged illustrates the illness perceptions of survivors and partners as well as the environment in which they were found. The cancer care environment is presented in the conceptual category experiencing contemporary cancer care settings. Receiving treatment quickly and without waiting was a positive experience for both partners and survivors; however partners experienced the information as massive and as causing concern. The period after discharge was being marked by uncertainty and loneliness, and partners tended to experience non-continuity in care as more problematic than the survivor did. The results showed different illness perceptions and a mismatch between illness perceptions among survivors and partners, presented in the conceptual category outlook on the cancer diagnosis. One illness perception, here presented among partners, focused on seeing the cancer diagnosis as a permanent life-changing event. The other illness perception, here presented among survivors, concentrated on

    Full Text Available Abstract Background International studies report that nurse clinics improve healing rates for the leg ulcer population. However, these studies did not necessarily deliver similar standards of care based on evidence in the treatment venues (home and clinic. A rigorous evaluation of home versus clinic care is required to determine healing rates with equivalent care and establish the acceptability of clinic-delivered care. Methods Health Services RCT was conducted where mobile individuals were allocated to either home or nurse clinic for leg ulcer management. In both arms, care was delivered by specially trained nurses, following an evidence protocol. Primary outcome: 3-month healing rates. Secondary outcomes: durability of healing (recurrence, time free of ulcers, HRQL, satisfaction, resource use. Data were collected at base-line, every 3 months until healing occurred, with 1 year follow-up. Analysis was by intention to treat.

    Despite being ranked number one globally in terms of health care cost per capita, the United States (US) has ranked as low as 37th in the world in terms of health care system performance. This poor performance for one of the most developed nations in the world has been reflected in the underachieved attempts of the multiple US health care systems at improving maternal and newborn health, according to the goals set in 2000 by the United Nations with Millennium Development Goals (MDG's) 5: Improve Maternal Health, and 4: Reduce Child Mortality. This paper will examine the progress, or lack thereof, over a period of 15 years of the fifth largest urban area in the US - Philadelphia, Pennsylvania - in its delivery of health care to pregnant women and their newborns. Using data collected from national, state, and city health agencies, trends concerning pregnancy care will be presented and compared to the target goals of MDG-5 and MDG-4, as well as Healthy People 2020, a US government-based initiative to improve health care of all Americans. Findings will demonstrate that urban areas such as Philadelphia are on a path of not reaching goals that have been set by the United Nations and the US government, and by some indicators are moving away in a negative direction from these goals.

    The concept of optimizing health care by understanding and generating knowledge from previous evidence, ie, the Learning Health-care System (LHS), has gained momentum and now has national prominence. Meanwhile, the rapid adoption of electronic health records (EHRs) enables the data collection required to form the basis for facilitating LHS. A prerequisite for using EHR data within the LHS is an infrastructure that enables access to EHR data longitudinally for health-care analytics and real time for knowledge delivery. Additionally, significant clinical information is embedded in the free text, making natural language processing (NLP) an essential component in implementing an LHS. Herein, we share our institutional implementation of a big data-empowered clinical NLP infrastructure, which not only enables health-care analytics but also has real-time NLP processing capability. The infrastructure has been utilized for multiple institutional projects including the MayoExpertAdvisor, an individualized care recommendation solution for clinical care. We compared the advantages of big data over two other environments. Big data infrastructure significantly outperformed other infrastructure in terms of computing speed, demonstrating its value in making the LHS a possibility in the near future. PMID:27385912

    Objectives In 2011, a workforce assessment conducted by the Georgia Maternal and Infant Health Research Group found that 52 % of Primary Care Service Areas outside metropolitan Atlanta, Georgia, had an overburdened or complete lack of obstetric care services. In response to that finding, this study's aim was twofold: to describe challenges faced by providers who currently deliver or formerly delivered obstetric care in these areas, and to identify essential core components that can be integrated into alternative models of care in order to alleviate the burden placed on the remaining obstetric providers. Methods We conducted 46 qualitative in-depth interviews with obstetricians, maternal-fetal medicine specialists, certified nurse midwives, and maternal and infant health leaders in Georgia. Interviews were digitally recorded, transcribed verbatim, uploaded into MAXQDA software, and analyzed using a Grounded Theory Approach. Results Providers faced significant financial barriers in service delivery, including low Medicaid reimbursement, high proportions of self-pay patients, and high cost of medical malpractice insurance. Further challenges in provision of obstetric care in this region were related to patient's late initiation of prenatal care and lacking collaboration between obstetric providers. Essential components of effective models of care included continuity, efficient use of resources, and risk-appropriate services. Conclusion Our analysis revealed core components of improved models of care that are more cost effective and would expand coverage. These components include closer collaboration among stakeholder populations, decentralization of services with effective use of each type of clinical provider, improved continuity of care, and system-wide changes to increase Medicaid benefits.

    Introduction: World Health Organization and American Society of Clinical Oncology recommend early integration of specialist palliative care in patients with cancer. This paper focuses on critical review of evidence on integration of early specialist palliative care in cancer care and patient-related outcomes. Methods: The question for the literature search was – Does integration of early specialist palliative care in cancer care influences patient-related outcomes? 31 articles related to literature search review question were included in this paper. Results: Ten patient-related outcomes of early specialist palliative care in adult cancer care was studied. Studies by Temel et al. (2012), Bakitas et al. (2009), Zimmermann et al. (2014), Rugno et al. (2014), Lowery et al. (2013) and Walker et al. (2014) showed early specialist palliative care improves health-related quality of life (HRQOL). Studies by Pirl et al. (2012), Lowery et al. (2013), and Walker et al. (2014) showed early specialist palliative care improved mood depression and anxiety. Studies by Zimmermann et al. and Rugno et al. (2014) showed symptom control benefit of early specialist palliative care. Studies by Temel (2010), Bakitas (2015) and Rugno et al. (2014) showed survival improvement with early specialist palliative care. All these studies were carried in ambulatory palliative care setting. No survival benefit of palliative care intervention was seen in inpatient palliative care setting. The studies by Geer et al. (2012), Rugno et al. (2014), and Lowery et al. (2013) showed that early palliative care intervention positively influences treatment decision making. All the studies showed that palliative care intervention group received less intravenous chemotherapy in last few weeks of life. Studies by Yoong et al. and Temel et al. (2011) shows early specialist palliative care improves advanced care planning. Studies by Temel et al. (2010), Greer et al. (2012), McNamara et al. (2013), Hui et al. (2014

    Full Text Available Delivery is considered as one of the most painful experiences of women’s life. The present study aimed to compare the effects of supportive care and acupressure on the pregnant women’s pain intensity and delivery outcome. In this experimental study, 150 pregnant women were randomly divided into supportive care, acupressure, and control groups. The intensity of pain was measured using Visual Analogue Scale (VAS. The supportive care group received both physical and emotional cares. In the acupressure group, on the other hand, BL32 acupoint was pressed during the contractions. Then, the data were analyzed using descriptive and inferential statistics. The results revealed significant difference among the three groups regarding the intensity of pain after the intervention (P<0.001. Besides, the highest rate of natural vaginal delivery was observed in the supportive care group (94% and the acupressure group (92%, while the highest rate of cesarean delivery was related to the control group (40% and the difference was statistically significant (P<0.001. The results showed that maternal supportive care and acupressure during labor reduced the intensity of pain and improved the delivery outcomes. Therefore, these methods can be introduced to the medical team as effective strategies for decreasing delivery pain. This trial is registered with the Iranian Registry of Clinical Trial Code IRCT2014011011706N5.

    Monitoring the current status of cancer care is essential for effective cancer control and high-quality cancer care. To address the information needs of patients and physicians in Japan, hospital-based cancer registries are operated in 397 hospitals designated as cancer care hospitals by the national government. These hospitals collect information on all cancer cases encountered in each hospital according to precisely defined coding rules. The Center for Cancer Control and Information Services at the National Cancer Center supports the management of the hospital-based cancer registry by providing training for tumor registrars and by developing and maintaining the standard software and continuing communication, which includes mailing lists, a customizable web site and site visits. Data from the cancer care hospitals are submitted annually to the Center, compiled, and distributed as the National Cancer Statistics Report. The report reveals the national profiles of patient characteristics, route to discovery, stage distribution, and first-course treatments of the five major cancers in Japan. A system designed to follow up on patient survival will soon be established. Findings from the analyses will reveal characteristics of designated cancer care hospitals nationwide and will show how characteristics of patients with cancer in Japan differ from those of patients with cancer in other countries. The database will provide an infrastructure for future clinical and health services research and will support quality measurement and improvement of cancer care. Researchers and policy-makers in Japan are encouraged to take advantage of this powerful tool to enhance cancer control and their clinical practice.

    Full Text Available Background: Riskesdas 2010 illustrates that birth deliveries by health workers in low-income community reached 69.3%; while deliveries were conducted health workers at health facilities only reached 55.4%. This illustrates that the health facility or program that has given local or central government has not run optimally. Methods:This study aims to determine antenatal care and birth delivery preferences in the community and what factors underlie the preference. The location of research is precisely in the area of Puskesmas Kassi-kassi, Makassar City. Results showed that the mother already has the knowledge, attitudes and behavior quite well in maintaining health. Society does not always take advantage of government facilities. Antinatal care is mostly done in the doctor or midwife in private practice for reasons of convenience and prestige; while health centers for labor is still the main choice for the cheapest. Conclusion: Urban community in Kassi Health Center area have many option other than health center the quality only type of services is factor related to costumer choice because they are able to finance the cost. Recommendation: Government need to involve the private sector and do not ignore the social economic and culture condition for the successful of program.

    Providing comprehensive care for patients with cancer is complex with regard to severe treatment-related side effects. Hundreds of thousands of patients with cancer visit the emergency department (ED) each year, and more than half report multiple visits. In the United States, few of the National Cancer Institute-designated cancer centers have an ED specifically for patients with cancer. EDs often are an overcrowded and expensive way in which to care for the urgent needs of patients with cancer. In addition, a looming shortage exists for both primary care providers and oncologists who can address symptom issues. As the Affordable Care Act is implemented, more patients will enter the healthcare system, placing a demand on providers that the current supply cannot meet. A report from the Institute of Medicine advocates that nurse practitioners (NPs) are more than competent to provide for the unique urgent care needs of patients with cancer. The aim of this article is to describe an NP-led urgent care center for patients with cancer and how that care center provides access to vital, expeditious, and cost-effective care.
