    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.

  2. Cancer - the delivery of nursing care

    International Nuclear Information System (INIS)

    This and the preceding article (Nursing Mirror, Sept. 1, 1978) form a slightly shortened version of Chap. 5 from Vol. 2 of the book 'Oncology for Nurses and Health Care Professionals', ed. R. Tiffany, (Allen and Unwin, Oct. 1978). Teletherapy was dealt with in part 1. Part 2 is concerned with radiotherapy using radioisotope implants and applicators and unsealed sources, and with surgery and chemotherapy, including side effects of anti-tumour drugs. The physical and psychological effects on the patient of these forms of treatment are discussed, and nursing care and radiological safety precautions for both patients and nursing staff are described.

    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. PMID:2801600

    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. PMID:25893925

    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

    Over a decade ago, the Institute of Medicine (IOM) presented Ensuring Quality Cancer Care in the United States, with recommendations for change (IOM, 1999). However, barriers to integrating palliative care (PC) to achieve high-quality care in cancer still remain. As novel therapeutic agents evolve, patients are living longer, and advanced cancer is now considered a chronic illness. In addition to complex symptom concerns, patients and family caregivers are burdened with psychological, social, and spiritual distress. Furthermore, data show that PC continues to be underutilized and inaccessible, and current innovative models of integrating PC into standard cancer care lack uniformity. The aim of this article is to address the existing barriers in implementing PC into our cancer care delivery system and discuss how the oncology advanced practice nurse plays an essential role in providing high-quality cancer care. We also review the IOM recommendations; highlight the work done by the National Consensus Project in promoting quality PC; and discuss a National Cancer Institute-funded program project currently conducted at a National Comprehensive Cancer Center, "Palliative Care for Quality of Life and Symptoms Concerns in Lung Cancer," which serves as a model to promote high-quality care for patients and their families.

Therefore, we reviewed literature for international guidelines and reorganized these useful factors associated with non-small-cell lung cancer (NSCLC recurrence as remedies in postoperative follow-up. Method: The population of interest for this review was patients who had been treated with complete resection for primary NSCLC and were in follow-up. Result: Guidelines on follow-up care for NSCLC vary internationally. Because of the production of progressive medical modalities, the current follow-up care should be corrected. Conclusion: The specific follow-up schedule for computed tomography imaging may be more or less frequent, depending upon risk factors for recurrence. Many different predictors of postoperative recurrence may help to optimize the patient selection for specified surveillance guidelines and personalized adjuvant therapies to prevent possibly occult micrometastases and to get a better outcome.

    Emerging challenges in health care delivery demand systems of clinical practice capable of ensuring safe and reliable patient care. Oncology in particular is recognized for its high degree of complexity and potential for adverse events. New models of student education hold promise for producing a health care workforce armed with skills in patient safety. This training may have a particular impact on risk reduction in cancer care and ultimately improve clinical performance in oncology. A 1-day student program focused on the principles of patient safety was developed for the third-year medical school class. The core curriculum consisted of an online patient safety module, root cause analyses of actual patient safety events, and simulation scenarios designed to invoke patient safety skills. The program was successfully implemented and received an average of 4.2/5 on evaluations pertaining to its importance and effectiveness. Student surveys demonstrated that 59 % of students were not previously aware of system-based approaches to improving safety, 51 % of students had witnessed or experienced a patient safety issue, while only 10 % reported these events. Students reported feeling more empowered to act on patient safety issues as a result of the program. Educational programs can provide medical students with a foundation for skill development in medical error reduction and help enhance an organization's culture of safety. This has the potential to reduce adverse events in complex patient care settings such as clinical oncology. PMID:25893923

    Without significant operational reform within the nation's health care delivery organizations, new financing models, payment systems, or structures are unlikely to realize their promise. Adapting insights from high-performing companies in other high-risk, high-cost, science- and technology-based industries, we propose the "care platform" as an organizing framework for internal operations in diversified provider organizations to increase the quality, reliability, and efficiency of care delivery. A care platform organizes "care production" around similar work, rather than organs or specialties; integrates standard and custom care processes; and surrounds them with specifically configured information and business systems. Such organizational designs imply new roles for physicians. PMID:18780920

Shared care models require oversight to ensure that primary responsibility is defined for the persons overall health situation, for screening of co-morbidities, defining indication to treat comorbidities, prescription of non-HIV medicines, etc. Intelligent bioinformatics platforms (i.e. generation of alerts if course of care deviates from a prior defined normality are being developed to assist in providing this oversight and to provide measure of quality. Although consensus exists to assess basic quality indicators of care, a comprehensive set of harmonized indicators are urgently needed to define best practise standards via benchmarking. Such a tool will be central to guide ongoing discussions on restructuring of models, as quality of care should not be compromised in this process.

    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, broader mutational profiles in solid tumors, and 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 a 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. PMID:27200294

    Effective drug delivery in pancreatic cancer treatment remains a major challenge. Because of the high resistance to chemo and radiation therapy, the overall survival rate for pancreatic cancer is extremely low. Recent advances in drug delivery systems hold great promise for improving cancer therapy. Using liposomes, nanoparticles, and carbon nanotubes to deliver cancer drugs and other therapeutic agents such as siRNA, suicide gene, oncolytic virus, small molecule inhibitor and antibody has been a success in recent pre-clinical trials. However, how to improve the specificity and stability of the delivered drug using ligand or antibody directed delivery represent a major problem. Therefore, developing novel, specific, tumor-targeted drug delivery systems is urgently needed for this terrible disease. This review summarizes the current progress on targeted drug delivery in pancreatic cancer, and provides important information on potential therapeutic targets for pancreatic cancer treatment.

    The US health care system has become increasingly unsustainable, threatened by poor quality and spiraling costs. Many Americans are not receiving recommended preventive care, including cancer screening tests. Passage of the Affordable Care Act in March 2010 has the potential to reverse this course by increasing access to primary care providers, extending coverage and affordability of health insurance, and instituting proven quality measures. In order for health care reform to succeed, it will require a stronger primary care workforce, a new emphasis on patient-centered care, and payment incentives that reward quality over quantity. Innovations such as patient-centered medical homes, accountable care organizations, and improved quality reporting methods are central features of a redesigned health care delivery system and will ultimately change the face of cancer care in the United States.

    1991-01-01

    The Interactive Telemedicine Systems (ITS) system was specifically developed to address the ever widening gap between our medical care expertise and our medical care delivery system. 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.

  14. Palliative Care in Lung Cancer.

    Shinde, Arvind M; Dashti, Azadeh

    2016-01-01

    Lung cancer is the most common cancer worldwide and is the leading cause of cancer death for both men and women in the USA. Symptom burden in patients with advanced lung cancer is very high and has a negative impact on their quality of life (QOL). Palliative care with its focus on the management of symptoms and addressing physical, psychosocial, spiritual, and existential suffering, as well as medically appropriate goal setting and open communication with patients and families, significantly adds to the quality of care received by advanced lung cancer patients. The Provisional Clinical Opinion (PCO) of American Society of Clinical Oncology (ASCO) as well as the National Cancer Care Network's (NCCN) clinical practice guidelines recommends early integration of palliative care into routine cancer care. In this chapter, we will provide an overview of palliative care in lung cancer and will examine the evidence and recommendations with regard to a comprehensive and interdisciplinary approach to symptom management, as well as discussions of goals of care, advance care planning, and care preferences.

  16. Small area variations in health care delivery.

    1973-12-14

    Health information about total populations is a prerequisite for sound decision-making and planning in the health care field. Experience with a population-based health data system in Vermont reveals that there are wide variations in resource input, utilization of services, and expenditures among neighboring communities. Results show prima facie inequalities in the input of resources that are associated with income transfer from areas of lower expenditure to areas of higher expenditure. Variations in utilization indicate that there is considerable uncertainty about the effectiveness of different levels of aggregate, as well as specific kinds of, health services. Informed choices in the public regulation of the health care sector require knowledge of the relation between medical care systems and the population groups being served, and they should take into account the effect of regulation on equality and effectiveness. When population-based data on small areas are available, decisions to expand hospitals, currently based on institutional pressures, can take into account a community's regional ranking in regard to bed input and utilization rates. Proposals by hospitals for unit price increases and the regulation of the actuarial rate of insurance programs can be evaluated in terms of per capita expenditures and income transfer between geographically defined populations. The PSRO's can evaluate the wide variations in level of services among residents of different communities. Coordinated exercise of the authority vested in these regulatory programs may lead to explicit strategies to deal directly with inequality and uncertainty concerning the effectiveness of health care delivery. Population-based health information systems, because they can provide information on the performance of health care systems and regulatory agencies, are an important step in the development of rational public policy for health.

    2012-10-01

    While there are operational, financial, and workforce barriers to integrating oncology with palliative care, part of the problem lies in ourselves, not in our systems. First, there is oncologists' "learned helplessness" from years of practice without effective medications to manage symptoms or training in how to handle the tough communication challenges every oncologist faces. Unless they and the fellows they train have had the opportunity to work with a palliative care team, they are unlikely to be fully aware of what palliative care has to offer to their patients at the time of diagnosis, during active therapy, or after developing advanced disease, or may believe that, "I already do that." The second barrier to better integration is the compassion fatigue many oncologists develop from caring for so many years for patients who, despite the oncologists' best efforts, suffer and die. The cumulative grief oncologists experience may go unnamed and unacknowledged, contributing to this compassion fatigue and burnout, both of which inhibit the integration of oncology and palliative care. Solutions include training fellows and practicing oncologists in palliative care skills (eg, in symptom management, psychological disorders, communication), preventing and treating compassion fatigue, and enhancing collaboration with palliative care specialists in caring for patients with refractory distress at any stage of disease. As more oncologists develop these skills, process their grief, and recognize the breadth of additional expertise offered by their palliative care colleagues, palliative care will become integrated into comprehensive cancer care.

    Full Text Available The aim of the study was to analyze the guidelines considering breastfeeding given by health professionals to women during prenatal care, delivery and postpartum care. Quantitative and descriptive work developed at Regional Pinheiros, Maringá-PR, from the registry in SisPreNatal, from May to August 2009. Data were collected through interviews conducted with parents at home, using a structured instrument. Participants were 36 mothers, most of whom received counseling for breastfeeding during prenatal (58.3%, maternity (87.6% and in nursing visits to newborn (84.6%. The prevalence of exclusive breastfeeding was 37.5%, even with the end of maternity leave. The rate is still below the recommended by the World Health Organization for exclusive breastfeeding. The present results may contribute to the monitoring of health actions and development of new strategies in the maintenance of exclusive breastfeeding.

    To control Medicaid costs, improve quality, and drive community engagement, the Oregon Health Authority introduced a new system of coordinated care organizations (CCOs). While CCOs resemble traditional Medicaid managed care, they have differences that have been deliberately designed to improve care coordination, increase accountability, and incorporate greater community governance. Reforms include global budgets integrating medical, behavioral, and oral health care and public health functions; risk-adjusted payments rewarding outcomes and evidence-based practice; increased transparency; and greater community engagement. The CCO model faces several implementation challenges. If successful, it will provide improved health care delivery, better health outcomes, and overall savings. PMID:25480844

    There is an increasing focus on the relative cost-effectiveness and sustainability of delivering high-quality cancer care, with most emphasis, debatably, given to cost control of innovative treatments. It is difficult to calculate all the direct and indirect contributors to the total cost of cancer treatment, but it is estimated that cancer drugs constitute 10% to 30% of the total cost of cancer care. A 2007 study in France showed the contribution of drug costs was less than 20%, with approximately 70% of the total expenditure on cancer accounted for by health care resource use, such as hospitalization. The U.K. government established the National Institute for Health and Care Excellence (NICE)-the dominant function of which is technology appraisal-to assess the clinical and cost-effectiveness of new pharmaceutical and biopharmaceutical products. This is to ensure that all National Health Service (NHS) patients have equitable access to the most clinically effective and cost-effective treatments that are viable. NICE has developed a transparent, public process to judge incremental cost-effectiveness using the quality-adjusted life year (QALY), which allows comparisons of cost-effectiveness across medical specialties. NICE has been both lauded and criticized-especially when it passes judgment on marginally effective but expensive anticancer drugs-but it provides a route to "rational rationing" and, therefore, may contribute to sustainable cancer care by highlighting the issue of affordable medicine. This implies a challenge to the wider oncology community as to how we might cooperate to introduce the concept of value-driven cancer care. PMID:27249712

    To deal with the suffering caused by childhood cancer, patients and their families use different coping strategies, among which, spirituality appears a way of minimizing possible damage. 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. Health care workers have been increasingly attentive to this dimension of care. However, it is necessary to improve their knowledge regarding the subject. The search highlighted that spirituality is considered a source of comfort and hope, contributing to a better acceptance of his/her chronic condition by the child with cancer, as well as by the family. Further up-to-date studies facing the subject are, thus, needed. It is also necessary to better train health care practitioners, so as to provide humanized care to the child with cancer.

    Raz, Nasibeh Rady; Akbarzadeh-T, Mohammad-R; Tafaghodi, Mohsen

    2015-12-01

    A biomimicry approach to nanonetworks is proposed here for targeted cancer drug delivery (TDD). The swarm of bioinspired nanomachines utilizes the blood distribution network and chemotaxis to carry drug through the vascular system to the cancer site, recognized by a high concentration of vascular endothelial growth factor (VEGF). Our approach is multi-scale and includes processes that occur both within cells and with their neighbors. The proposed bionanonetwork takes advantage of several organic processes, some of which already occur within the human body, such as a plate-like structure similar to those of red blood cells for more environmental contact; a berry fruit architecture for its internal multi-foams architecture; the penetrable structure of cancer cells, tissue, as well as the porous structure of the capillaries for drug penetration; state of glycocalyx for ligand-receptor adhesion; as well as changes in pH state of blood and O 2 release for nanomachine communication. For a more appropriate evaluation, we compare our work with a conventional chemotherapy approach using a mathematical model of cancer under actual experimental parameter settings. Simulation results show the merits of the proposed method in targeted cancer therapy by improving the densities of the relevant cancer cell types and VEGF concentration, while following more organic and natural processes.

    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.

    2016-09-01

    Small interfering RNA (siRNA) has gained attention as a potential therapeutic reagent due to its ability to inhibit specific genes in many genetic diseases. For many years, studies of siRNA have progressively advanced toward novel treatment strategies against cancer. Cancer is caused by various mutations in hundreds of genes including both proto-oncogenes and tumor suppressor genes. In order to develop siRNAs as therapeutic agents for cancer treatment, delivery strategies for siRNA must be carefully designed and potential gene targets carefully selected for optimal anti-cancer effects. In this review, various modifications and delivery strategies for siRNA delivery are discussed. In addition, we present current thinking on target gene selection in major tumor types. PMID:27259398

    Abrams, D I; Guzman, M

    2015-06-01

    Cannabis has been used in medicine for thousands of years prior to achieving its current illicit substance status. Cannabinoids, the active components of Cannabis sativa, mimic the effects of the endogenous cannabinoids (endocannabinoids), activating specific cannabinoid receptors, particularly CB1 found predominantly in the central nervous system and CB2 found predominantly in cells involved with immune function. Delta-9-tetrahydrocannabinol, the main bioactive cannabinoid in the plant, has been available as a prescription medication approved for treatment of cancer chemotherapy-induced nausea and vomiting and anorexia associated with the AIDS wasting syndrome. Cannabinoids may be of benefit in the treatment of cancer-related pain, possibly synergistic with opioid analgesics. Cannabinoids have been shown to be of benefit in the treatment of HIV-related peripheral neuropathy, suggesting that they may be worthy of study in patients with other neuropathic symptoms. Cannabinoids have a favorable drug safety profile, but their medical use is predominantly limited by their psychoactive effects and their limited bioavailability. PMID:25777363

    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.

    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.

    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. PMID:25533732

    Satisfaction with care is important to cancer survivors' health outcomes. Satisfaction with care is not equal for all cancer survivors, and sexual minority (i.e., lesbian, gay, and bisexual) cancer survivors may experience poor satisfaction with care. Data were drawn from the 2010 LIVESTRONG national survey. The final sample included 207 sexual minority cancer survivors and 4,899 heterosexual cancer survivors. Satisfaction with care was compared by sexual orientation, and a Poisson regression model was computed to test the associations between sexual orientation and satisfaction with care, controlling for other relevant variables. Sexual minority cancer survivors had lower satisfaction with care than did heterosexual cancer survivors (B = -0.12, SE = 0.04, Wald χ(2) = 9.25, phealth disparities reported among sexual minority cancer survivors.

    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

    Streu, Erin

    2016-05-01

    Increasing weight and body fat composition has an impact on cancer detection and staging. Obese women are less likely to engage in breast and cervical screening practices. Excessive adipose tissue makes physical assessment more difficult, and patients with a BMI greater than 35 kg/m2 may have deeper and wider pelvic structures, which make internal examinations problematic. A retrospective review of 324 primary surgical patients found that patients with a BMI greater than 40 kg/m2 are seven times less likely to undergo complete surgical staging for endometrial cancer compared with individuals with a BMI less than 40 kg/m2. In addition, healthcare provider bias against the need for screening, feelings of discomfort and embarrassment, as well as patient's fears of guilt, humiliation, and shame pose significant barriers to addressing the issue of obesity in clinical care with patients and family members.

    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.

    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.

  12. Fatigue and the delivery of medical care

    LENUS (Irish Health Repository)

    Murphy, JFA

    2011-01-01

    Lack of sleep has well established effects on physiological, cognitive and behavioural functionality. 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.

    Full Text Available Background: The aim of this study was to determine the impact of important social and technological trends on health care delivery, in the context of developing “Iran's Health System Reform Plan by 2025”.Methods: A detailed review of the national and international literature was done to identify the main trends affecting health system. To collect the experts’ opinions about important trends and their impact on health care delivery, Focus Group Discussions (FGDs and semi-structured in-depth interviews techniques were used. The study was based on the STEEP model. Final results were approved in an expert’s panel session.Results: The important social and technological trends, affecting health system in Iran in the next 15 years are demographic transition, epidemiologic transition, increasing bio-environmental pollution, increasing slums, increasing private sector partnership in health care delivery, moving toward knowledge-based society, development of information and communication technology, increasing use of high technologies in health system, and development of traditional and alternative medicine. The opportunities and threats resulting from the above mentioned trends were also assessed in this study.Conclusion: Increasing healthcare cost due tosome trends like demographic and epidemiologic transition and uncontrolled increase in using new technologies in health care is one of the most important threats that the health system will be facing. The opportunities that advancement in technology and moving toward knowledge-based society create are important and should not be ignored.

    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. PMID:8242586

    The burden of cancer is growing, and the disease is becoming a major economic expenditure for all developed countries. In 2008, the worldwide cost of cancer due to premature death and disability (not including direct medical costs) was estimated to be US$895 billion. This is not simply due to an increase in absolute numbers, but also the rate of increase of expenditure on cancer. What are the drivers and solutions to the so-called cancer-cost curve in developed countries? How are we going to afford to deliver high quality and equitable care? Here, expert opinion from health-care professionals, policy makers, and cancer survivors has been gathered to address the barriers and solutions to delivering affordable cancer care. Although many of the drivers and themes are specific to a particular field-eg, the huge development costs for cancer medicines-there is strong concordance running through each contribution. Several drivers of cost, such as over-use, rapid expansion, and shortening life cycles of cancer technologies (such as medicines and imaging modalities), and the lack of suitable clinical research and integrated health economic studies, have converged with more defensive medical practice, a less informed regulatory system, a lack of evidence-based sociopolitical debate, and a declining degree of fairness for all patients with cancer. Urgent solutions range from re-engineering of the macroeconomic basis of cancer costs (eg, value-based approaches to bend the cost curve and allow cost-saving technologies), greater education of policy makers, and an informed and transparent regulatory system. A radical shift in cancer policy is also required. Political toleration of unfairness in access to affordable cancer treatment is unacceptable. The cancer profession and industry should take responsibility and not accept a substandard evidence base and an ethos of very small benefit at whatever cost; rather, we need delivery of fair prices and real value from new technologies

    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. PMID:27092363

    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.

    Full Text Available Abstract Background Primary care reform in Ontario, Canada started with the introduction of new enrollment models, the two largest of which are Family Health Networks (FHNs, a capitation-based model, and Family Health Groups (FHGs, a blended fee-for-service model. The purpose of this study was to evaluate differences in performance between FHNs and FHGs and to compare performance before and after physicians joined these new primary care groups. Methods This study used Ontario administrative claims data to compare performance measures in FHGs and FHNs. The study population included physicians who belonged to a FHN or FHG for at least two years. Patients were included in the analyses if they enrolled with a physician in the two years after the physician joined a FHN or FHG, and also if they saw the physician in a two year period prior to the physician joining a FHN or FHG. Performance was derived from the administrative data, and included measures of preventive screening for cancer (breast, cervical, colorectal and chronic disease management (diabetes, heart failure, asthma. Results Performance measures did not vary consistently between models. In some cases, performance approached current benchmarks (Pap smears, mammograms. In other cases it was improving in relation to previous measures (colorectal cancer screening. There were no changes in screening for cervical cancer or breast cancer after joining either a FHN or FHG. Colorectal cancer screening increased in both FHNs and FHGs. After enrolling in either a FHG or a FHN, prescribing performance measures for diabetes care improved. However, annual eye examinations decreased for younger people with diabetes after joining a FHG or FHN. There were no changes in performance measures for heart failure management or asthma care after enrolling in either a FHG or FHN. Conclusions Some improvements in preventive screening and diabetes management which were seen amongst people after they enrolled may be

  3. Radiotherapy in Palliative Cancer Care: Development and Implementation

    International Nuclear Information System (INIS)

    on Cancer, the International Union against Cancer and the International Network for Cancer Treatment and Research (INCTR), to design, implement and integrate comprehensive and cost effective national cancer programmes across all areas of cancer control and treatment, including palliative care. It is important to note that palliative care is not only care of the dying, since even with advanced and disseminated cancer, patients are now living longer. The goal of palliative care is to relieve symptoms effectively and efficiently and to maintain the maximum quality of life for the duration of the patient's life. The interventions recommended depend on the patient's clinical status, severity of disease, and the location of the symptomatic site. Radiotherapy has an important role to play as a cost effective and simple method to relieve symptoms caused by bone or brain metastases, tumour bleeding, or visceral/lymphovascular obstruction due to cancer. This report was written following an IAEA consultants meeting in October 2007 and further electronic communications. The aims of the discussions were to: recognize and document the diversity and complexity of cancer types, rates, diagnoses and treatments worldwide; and to provide guidelines to ensure optimum delivery of comprehensive palliative cancer care. This report makes five recommendations: 1. The management and control of cancer symptoms is needed in all health care systems. There is a shortage of palliative care specialists in all health systems, relative to the number of cancer patients needing palliative care. 2. Because palliative care specialists can reach only a small proportion of the patients in need, palliative care principles and techniques should form a core element of the medical education for all health care providers, and especially for those who regularly treat cancer patients. 3. There is a specific need for training in comprehensive palliative care amongst the radiation oncology community. Radiation

    2015-04-01

    Chronic disease has become the great epidemic of our times, responsible for 75% of total health care costs and the majority of deaths in the US. Our current delivery model is poorly constructed to manage chronic disease, as evidenced by low adherence to quality indicators and poor control of treatable conditions. New technologies have emerged that can engage patients and offer additional modalities in the treatment of chronic disease. Modifying our delivery model to include team-based care in concert with patient-centered technologies offers great promise in managing the chronic disease epidemic. PMID:25460529

    Preventive services can reduce the morbidity of sickle cell disease (SCD) in children but are delivered unreliably. We conducted a retrospective cohort study of children aged 2 to 5 years with SCD, evaluating each child for 14 months and expecting that he/she should receive ≥75% of days covered by antibiotic prophylaxis, ≥1 influenza immunization, and ≥1 transcranial Doppler ultrasound (TCD). We used logistic regression to quantify the relationship between ambulatory generalist and hematologist visits and preventive services delivery. Of 266 children meeting the inclusion criteria, 30% consistently filled prophylactic antibiotic prescriptions. Having ≥2 generalist, non-well child care visits or ≥2 hematologist visits was associated with more reliable antibiotic prophylaxis. Forty-one percent of children received ≥1 influenza immunizations. Children with ≥2 hematologist visits were most likely to be immunized (62% vs. 35% among children without a hematologist visit). Only 25% of children received ≥1 TCD. Children most likely to receive a TCD (42%) were those with ≥2 hematologist visits. One in 20 children received all 3 preventive services. Preventive services delivery to young children with SCD was inconsistent but associated with multiple visits to ambulatory providers. Better connecting children with SCD to hematologists and strengthening preventive care delivery by generalists are both essential. PMID:26950087

    2016-08-01

    Current alternative payment models (APMs) that move away from traditional fee-for-service payment often have explicit goals to reduce utilization in episodic settings, such as emergency departments (ED). We apply the new HHS payment reform taxonomy to illustrate a pathway to success for EDs in APMs. Despite the unique challenges faced by EDs, a variety of category 2 and 3 APMs may be applicable to EDs in the short- and long term to improve efficiency and value. Full and partially capitated models create incentives for longitudinal and episodic ED providers and payers to unite to create interventions to reduce costs. However, prospective attribution remains a challenge for EDs because of exogenous demand, which makes it important for EDs to be one of the components of capitated payment along with longitudinal providers who can exert greater control on overall care demands. The goal of payment and delivery reforms in ED care is to improve population health across the continuum of acute and longitudinal care. In order to deliver cost-conscious care, ED providers will need additional resources, expanded information, and new processes and metrics to facilitate cost-conscious decisions. Improved availability of electronic information across settings, evidence generated from developing and testing acute care-specific payment models, and engaging acute care providers directly in reform efforts will help meet these goals.

    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.

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.

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

    Institute of Scientific and Technical Information of China (English)

    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.

    Lung cancer is the most malignant cancer today. The treatment of lung cancer continues to be a challenge for oncologists. The direct delivery of chemotherapeutic agents to the lungs could represent a novel therapeutic approach for patients with pulmonary metastases. The large alveolar surface area, the low thickness of the epithelial barrier, and an extensive vascularization make the pulmonary route an ideal route for administration of oncolytics. This paper reviews the research performed ove...

    Purpose - The focused factory is one of the concepts that decision-makers have adopted for improving health care delivery. However, disorganized definitions of focus have led to findings that cannot be utilized systematically. The purpose of this paper is to discuss strategic options to focus health care operations. Design/methodology/approach - First the literature on focus in health care is reviewed revealing conceptual challenges. Second, a definition of focus in terms of demand and requisite variety is defined, and the mechanisms of focus are explicated. A classification of five focus strategies that follow the original idea to reduce variety in products and markets is presented. Finally, the paper examines managerial possibilities linked to the focus strategies. Findings - The paper proposes a framework of five customer-oriented focus strategies which aim at reducing variety in different characteristics of care pathways: population; urgency and severity; illnesses and symptoms; care practices and processes; and care outcomes. Research limitations/implications - Empirical research is needed to evaluate the costs and benefits of the five strategies and about system-level effects of focused units on competition and coordination. Practical implications - Focus is an enabling condition that needs to be exploited using specific demand and supply management practices. It is essential to understand how focus mechanisms differ between strategies, and to select focus that fits with organization's strategy and key performance indicators. Originality/value - Compared to previous more resource-oriented approaches, this study provides theoretically solid and practically relevant customer-oriented framework for focusing in health care.

    NASA's Space Station is viewed as the beginning of man's permanent presence in space. This paper presents the guidelines being developed by NASA's medical community in preparing a quality, permanent health care delivery system for Space Station. The guidelines will be driven by unique Space Station requirements such as mission duration, crew size, orbit altitude and inclination, EVA frequency and rescue capability. The approach will emphasize developing a health care system that is modular and flexible. It will also incorporate NASA's requirements for growth capability, commonality, maintainability, and advanced technology development. Goals include preventing unnecessary rescue attempts, as well as maintaining the health and safety of the crew. Proper planning will determine the levels of prevention, diagnosis, and treatment necessary to achieve these goals.

    2001-01-01

    Taiwan reached the World Health Organization (WHO) benchmark of 7% aged 65 and over for defining an aging population only as recently as 1993. With this proportion projected to double to 14% by 2020, Taiwan faces a rapid increase in need for long-term care. This article presents an account of the current service delivery system, which is divided between health and social affairs administrations, with a substantial role also taken by the Veteran Administration, and growing provision of facilities that operate outside the government-registered system. While a basic level of both institutional and community care services has developed, they are not organized into an integrated service system. Problems arising from the divisions and overlaps in responsibility are identified in relation to competition for resources, differences in regulation and eligibility, funding arrangements and misallocation of resources, and divergent views about the philosophical basis of long-term care. Other aspects of services fall under each jurisdiction, but there is also some overlap. A case study of Taiwan's second largest city, Kaohsiung City, reports the outcomes of these divisions as a thin spread of a range of services rather than a coordinated service network. Several planning exercises have been undertaken in recent years to address these problems, and although at an early stage of implementation, the outcomes of these plans are seen as shaping the future directions of long-term care in Taiwan.

    Noonan, Erika M; Farrell, Timothy W

    2016-05-01

    This summary of the American Cancer Society Prostate Cancer Survivorship Care Guidelines targets primary care physicians who coordinate care of prostate cancer survivors with subspecialists. Prostate cancer survivors should undergo prostate-specific antigen screening every six to 12 months and digital rectal examination annually. Surveillance of patients who choose watchful waiting for their prostate cancer should be conducted by a subspecialist. Any hematuria or rectal bleeding must be thoroughly evaluated. Prostate cancer survivors should be screened regularly for urinary incontinence and sexual dysfunction. Patients with predominant urge incontinence symptoms, which can occur after surgical and radiation treatments, may benefit from an anticholinergic agent. If there is difficulty with bladder emptying, a trial of an alpha blocker may be considered. A phosphodiesterase type 5 inhibitor can effectively treat sexual dysfunction following treatment for prostate cancer. Osteoporosis screening should occur before initiation of androgen deprivation therapy, and patients treated with androgen deprivation therapy should be monitored for anemia, metabolic syndrome, and vasomotor symptoms. Healthy lifestyle choices should be encouraged, including weight management, regular physical activity, proper nutrition, and smoking cessation. Primary care physicians should be vigilant for psychosocial distress, including depression, among prostate cancer survivors, as well as the potential impact of this distress on patients' family members and partners.

    1993-05-01

    Until 1989, the Commonwealth of Massachusetts operated a mandated care program known as Services for Handicapped Children (SHC) for children with cleft lip/palate or craniofacial anomalies. During the mid 1980s, the federal government reduced its block grant funds and encouraged the Commonwealth of Massachusetts to develop Project SERVE to address this changing fiscal reality. The principal outcome of Project SERVE was the recommendation that the SHC direct care programs, including all craniofacial and cleft palate clinics, should be dismantled over a number of years. However, due to the economic recession, all government funding was suddenly withdrawn from cleft palate teams and the state-run SHC clinics were abruptly dissolved. To treat patients left without coordinated care, former team members reassembled and began a new craniofacial team based at the University of Massachusetts Medical Center. Difficulties with the transition of the clinic included recruiting and retaining team members; remuneration procedures for team members; maintenance of patient records previously kept by the state; coordination of clinical/clerical responsibilities; identifying a physical locale to hold the clinics; and solicitation of referring health care provider referrals and follow-up. All these issues required specific interventions that are presented in this paper. Project SERVE, begun under federal auspices, in the Commonwealth of Massachusetts, has recently been promoted as a model for a new and improved approach to the management of cleft palate and craniofacial care delivery nationwide. Awareness of the potential for abrupt, radical change in funding for federally mandated cleft/craniofacial care is essential, and a successful transition to a medical center-based model is possible using the procedures established at our center.

    2014-01-01

    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"? PMID:24896558

    Full Text Available Introduction: Being a cancer patient is a unique and singular. The cancer disease associated with pain and suffering is a challenging process for the sufferer, for whom have around or for those caring for the sick. Pain, considered the 5 th vital sign, is often identified as the main complaint of our patients suffering from cancer. We dare to say that to explore the essence of the care provided by nurses and primary health care to cancer patients with prolonged pain at the time found in his home and family, we would be helping to build a know -how by itself, with positive externalities for patients, families, professionals and nursing itself. Methods: Ask "What does Care for Nurses and primary health care for cancer patients with prolonged pain in time for your family?" we may lead the cornerstone of our problems, by studying quantitative nature using a questionnaire and a significance level of care. Results: the average age is 59.27 years, mostly women, 51% are married and in 29.8% of studies has only completed the first cycle of education. The majority of cancer patients who participated in this study share a room with a relative. In regard to aspects of their pain, cancer patients referred to 47.1% of cases, that their pain started weeks ago and 38.5% even refers to the pain persists for months. The pain felt by these patients is not the severe type, in 68.3% of cases, and has an average intensity of 5, although we have 25% of these patients with pain greater than a 6.75. The Meaning of Caring scale applied to the group of nurses who provide care at primary health reveals an alpha of 0.8857 and 0.9025 standardized alpha. The Meaning of Caring scale applied to the group of cancer patients with prolonged pain at the time they are at home shows an alpha of 0.6672and 0.7374 standardized alpha. The Meaning of Caring scale applied to the group of cancer family patients with prolonged pain shows an alpha of 0.6712 and an alpha standardized 0

    2015-11-01

    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.

    Quality of health care is a hot topic, especially with regard to cancer. Although rectal cancer is, in many aspects, a model oncologic entity, there seem to be substantial differences in quality of care between countries, hospitals and physicians. PROCARE, a Belgian multidisciplinary national project to improve outcome in all patients with rectum cancer, identified a set of quality of care indicators covering all aspects of the management of rectal cancer. This set should permit national and international benchmarking, i.e. comparing results from individual hospitals or teams with national and international performances with feedback to participating teams. Such comparison could indicate whether further improvement is possible and/or warranted. PMID:22103052

    Answer questions and earn CME/CNE The American Cancer Society Head and Neck Cancer Survivorship Care Guideline was developed to assist primary care clinicians and other health practitioners with the care of head and neck cancer survivors, including monitoring for recurrence, screening for second primary cancers, assessment and management of long-term and late effects, health promotion, and care coordination. A systematic review of the literature was conducted using PubMed through April 2015, and a multidisciplinary expert workgroup with expertise in primary care, dentistry, surgical oncology, medical oncology, radiation oncology, clinical psychology, speech-language pathology, physical medicine and rehabilitation, the patient perspective, and nursing was assembled. While the guideline is based on a systematic review of the current literature, most evidence is not sufficient to warrant a strong recommendation. Therefore, recommendations should be viewed as consensus-based management strategies for assisting patients with physical and psychosocial effects of head and neck cancer and its treatment.

  12. Liposome-based drug delivery in breast cancer treatment

    International Nuclear Information System (INIS)

    Drug delivery systems can in principle provide enhanced efficacy and/or reduced toxicity for anticancer agents. Long circulating macromolecular carriers such as liposomes can exploit the 'enhanced permeability and retention' effect for preferential extravasation from tumor vessels. Liposomal anthracyclines have achieved highly efficient drug encapsulation, resulting in significant anticancer activity with reduced cardiotoxicity, and include versions with greatly prolonged circulation such as liposomal daunorubicin and pegylated liposomal doxorubicin. Pegylated liposomal doxorubucin has shown substantial efficacy in breast cancer treatment both as monotherapy and in combination with other chemotherapeutics. Additional liposome constructs are being developed for the delivery of other drugs. The next generation of delivery systems will include true molecular targeting; immunoliposomes and other ligand-directed constructs represent an integration of biological components capable of tumor recognition with delivery technologies

    Information on 934 never married mothers (Single) were compared with 301 who were widowed, divorced or separated (Once-married) and 15 225 who were married at the time of delivery and were part of the 1970 British Births Survey. Once the maternal age and parity differences had been taken into account the major findings concerned the mothers' health behaviour and the obstetric care they received. Single and Once-married mothers were markedly less likely than the Married group to have used contraceptives in the 18 months before conception, to know accurately the date of the last menstrual period, to commence antenatal care before the third trimester, and to attend antenatal or parentcraft classes. Both groups were more likely to smoke, the Once-married group having an especially high rate of heavy smokers. Single mothers were more likely to be anaemic during pregnancy and the Once-married to have a history of bleeding. Both groups were more likely to be delivered in a consultant unit. Relatively high proportions of Single and Once-married mothers had delivered without any pain relief. PMID:3803266

    Objective: Home care of the elderly with cancer. After the development of a program of oncology home care and over a period of five years, we believe that the evaluation allows us to have our proposal and challenges in the continuity of the program. This evidence is based in our old advanced Uruguayan population, and consequently increase this cancer population, we should define which pointed toward our objective, in order to get the best quality life. After one year with a project based on general rules, the evidence threw an evaluation, that we should review the model of care with which we were working. We continue to Auto-care model Dorothea Orem. The main objective became quality of life:Take care as the primary Older Adult; Specific care their cancer to become symptomatic secondary complications to the evolution of tumor biology; Secondary prevention of cause therapeutic effect; Family integration, without changing the pace of life that the elderly had before being with cancer. Nursing challenge: Maintain autonomy achieved in these 5 years. Deepen the social equilibrium that we are committed daily between patient and family.Do not miss the professionalism achieved today.Proposal for nursing: Consider a wide field of nursing and for this achievement is need knowledge of 2nd level of community work, knowledge Clinical knowledge in Oncology Nursing, autonomy in decision making. For older adults with cancer: No out of its middle. Maintain priority habits and customs. Do not let it lose their self-esteem with their own values. Caution changes must take care to better manage the evolution of their illness. Conclusion: Oncology nursing is a specialty. Without this formation will be ever more away the development of these programs in our environment, or fall in applying for only economic convenience, losing professionalism.

    Although palliative care has been developed and implemented as care for cancer pain, it is holistic care for suffering that includes physical, psychosocial and spiritual pain of life-threatening illness. It turned out that non-cancer patients in the end-stage are also suffering from various pain that should be treated as cancer patients. Trajectories of illness in non-cancer patients are with more gradual decline than those of cancer patients with steady progression and it is often difficult to make decision about end-of-life. The purpose of advance care planning was originally to help describe legal documents. This process is proved to contribute to improving QOL of patients and their families to discuss preference, hope, economic problems, spiritual question as well as medical treatment In Japan guideline of decision making process in end-of-life stage has been established. A program of communication training in end-of-life discussion has been made. Under current situation some comments on the role of anesthesiologists are also mentioned. PMID:27097506

    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

    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. PMID:25936529

    Objective To study factors that influence receipt of preventive care in older cancer survivors. Methods We analyzed a nationally representative sample of 12,458 older adults from the 2003 Medicare Current Beneficiary Survey. Factors associated with non-receipt of preventive care were explored among cancer and non-cancer survivors, using logistic regression. Results Among cancer survivors, 1,883 were diagnosed >one year at survey completion. A cancer history was independently associated with receipt of mammogram (AOR=1.57, 95%CI=1.34–1.85), flu shot (AOR=1.33, 95%CI=1.16–1.53), measurement of total cholesterol in the previous six months (AOR=1.20, 95%CI=1.07–1.34), pneumonia vaccination (AOR=1.33, 95%CI=1.18–1.49), bone mineral density (BMD) testing (AOR=1.38, 95%CI=1.21–1.56) and lower endoscopy (AOR=1.46, 95%CI=1.29–1.65). However, receipt of preventive care was not optimal among older cancer survivors with only 51.2% of female cancer survivors received a mammogram, 63.8% of all cancer survivors received colonoscopy, and 42.5% had BMD testing. Among cancer survivors, factors associated with non-receipt of mammogram included age ≥85 years (AOR=0.43, 95%CI=0.26–0.74) and scoring ≥three points on the Vulnerable Elders Survey-13 (AOR=0.94, 95%CI=0.80–1.00). Factors associated with non-receipt of colonoscopy included low education (AOR=0.43, 95%CI=0.27–0.68) and rural residence (AOR=0.51, 95%CI=0.34–0.77). Factors associated with non-receipt of BMD testing included age ≥70 (AOR=0.59, 95%CI=0.39–0.90), African American race (AOR=0.51, 95%CI=0.27–0.95), low education (AOR=0.23, 95%CI=0.14–0.38) and rural residence (AOR=0.43, 95%CI=0.27–0.70). Conclusion Although older cancer survivors are more likely to receive preventive care services than other older adults, the prevalence of receipt of preventive care services is low. PMID:25547206

  5. Inequity in Cancer Care: A Global Perspective

    International Nuclear Information System (INIS)

    The strategies of United Nations system organizations such as the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) are based on guiding principles, the attainment of health equality being an important one. Therefore, their strategies focus on the needs of low and middle income countries and of vulnerable and marginalized populations. The IAEA is committed to gender equality. In keeping with the United Nations policies and agreements on both gender equality and gender mainstreaming, the IAEA has the responsibility of integrating gender equality into its programmes, as well as for contributing to worldwide gender equality. In addition, the IAEA strongly emphasizes the attainment of the United Nations Millennium Development Goals, of which gender equality is a central tenet. This publication focuses on the issue of inequality (disparity) as it applies to cancer care in general, and access to prevention, screening, palliative and treatment services in particular. The problem of inequality in access to radiation oncology services is addressed in detail. Access to cancer care and radiotherapy services for women and children is specifically considered, reflecting the currently published literature. The report is aimed at radiotherapy professionals, health programme managers and decision makers in the area of cancer control. It was developed to create awareness of the role of socioeconomic inequality in access to cancer care, and to eventually mobilize resources to be equitably allocated to public health programmes in general, and to cancer control and radiotherapy programmes in particular

    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.

    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. PMID:27071534

    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. PMID:27391996

    A retrospective cross-sectional survey was conducted to assess key practices and costs relating to home- and institutional delivery care in rural Rajasthan, India. One block from each of two sample districts was covered (estimated population--279,132). Field investigators listed women who had delivered in the past three months and contacted them for structured case interview. In total, 1947 (96%) of 2031 listed women were successfully interviewed. An average of 2.4 and 1.7 care providers attended each home- and institutional delivery respectively. While 34% of the women delivered in health facilities, modem care providers attended half of all the deliveries. Intramuscular injections, intravenous drips, and abdominal fundal pressure were widely used for hastening delivery in both homes and facilities while post-delivery injections for active management of the third stage were administered to a minority of women in both the venues. Most women were discharged prematurely after institutional delivery, especially by smaller health facilities. The cost of accessing home-delivery care was Rs 379 (US$ 8) while the mean costs in facilities for elective, difficult vaginal deliveries and for caesarean sections were Rs 1336 (US$ 30), Rs 2419 (US$ 54), and Rs 11,146 (US$ 248) respectively. Most families took loans at high interest rates to meet these costs. It is concluded that widespread irrational practices by a range of care providers in both homes and facilities can adversely affect women and newborns while inadequate observance of beneficial practices and high costs are likely to reduce the benefits of institutional delivery, especially for the poor. Government health agencies need to strengthen regulation of delivery care and, especially, monitor perinatal outcomes. Family preference for hastening delivery and early discharge also require educational efforts. PMID:19489423

    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.

    Cancer survivorship care plans (SCPs) have been recommended to improve clinical care and patient outcomes. Research is needed to establish their efficacy and identify best practices. Starting in 2015, centers accredited by the American College of Surgeons Commission on Cancer must deliver SCPs to patients completing primary cancer treatment with curative intent. We describe how we established routine SCP delivery at the Robert H Lurie Comprehensive Cancer Center in Chicago, Illinois, using the Quality Implementation Framework. We evaluated local practices, gathered clinician and patient stakeholder input, developed customized SCP templates within the electronic health record (EHR), and implemented 2 complementary delivery models. Clinician interviews (n = 41) and survey responses (n = 12), along with input from patients (n = 68) and a patient advisory board (n = 15), indicated support for SCPs and survivorship services. To promote feasible implementation and leverage existing workflows, we harmonized 2 SCP delivery models: integrated care within clinics where patients received treatment, and referral to a centralized survivorship clinic. We are implementing SCP delivery with prominent disease sites and will extend services to survivors of other cancers in the future. We developed four electronic disease-specific SCP templates for breast, colorectal, lung, and prostate cancers and a fifth, generic template that can be used for other malignancies. The templates reduced free-text clinician entry by auto-populating 20% of the fields from existing EHR data, and using drop-down menus for another 65%. Mean SCP completion time is 12 minutes (range, 10-15; n = 64). We designed our framework to facilitate ongoing evaluation of implementation and quality improvement.

    2014-07-01

    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

    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 is considered as one of the most severe health problems and is currently the third most common cause of death in the world after heart and infectious diseases. Novel therapies are constantly being discovered, developed and trialed. Many of the current anticancer agents exhibit non-ideal pharmaceutical and pharmacological properties and are distributed non-specifically throughout the body. This results in death of the both normal healthy and malignant cells and substantially leads to accruing a variety of serious toxic side effects. Therefore, the efficient systemic therapy of cancer is almost impossible due to harmful side effects of anticancer agents to the healthy organs and tissues. Furthermore, several problems such as low bioavailability of the drugs, low drug concentrations at the site of action, lack of drug specificity and drug-resistance also cause many restrictions on clinical applications of these drugs in the tumor therapy. Different types of the liposomal formulations have been used in medicine due to their distinctive advantages associated with their structural flexibility in the encapsulation of various agents with different physicochemical properties. They can also mediate delivery of the cargo to the appropriate cell type and subcellular compartment, reducing the effective dosage and possible side effects which are related to high systemic concentrations. Therefore, these novel systems were found very promising and encouraging dosage forms for the treatment of different types of cancer by increasing efficiency and reducing the systemic toxicity due to the specific drug delivery and targeting.

    Despite being declared a basic human right, access to adult and pediatric palliative care for millions of individuals in need in low- and middle-income countries (LMICs) continues to be limited or absent. The requirement to make palliative care available to patients with cancer is increasingly urgent because global cancer case prevalence is anticipated to double over the next two decades. Fifty percent of these cancers are expected to occur in LMICs, where mortality figures are disproportionately greater as a result of late detection of disease and insufficient access to appropriate treatment options. Notable initiatives in many LMICs have greatly improved access to palliative care. These can serve as development models for service scale-up in these regions, based on rigorous evaluation in the context of specific health systems. However, a multipronged public health approach is needed to fulfill the humane and ethical obligation to make palliative care universally available. This includes health policy that supports the integration of palliative care and investment in systems of health care delivery; changes in legislation and regulation that inappropriately restrict access to opioid medications for individuals with life-limiting illnesses; education and training of health professionals; development of a methodologically rigorous data and research base specific to LMICs that encompasses health systems and clinical care; and shifts in societal and health professional attitudes to palliative and end-of-life care. International partnerships are valuable to achieve these goals, particularly in education and research, but leadership and health systems stewardship within LMICs are critical factors that will drive and implement change.

When the service delivered by the care provider is in accordance with what the recipients of health care expect, then quality in health care is considered to be present. There are several factors in higher medical education and health care that are responsible for the emergence of QA. These include externally imposed obligations requiring demonstration of public accountability and responsibility from educational institutions, as well as the need for activity-specific information by policy makers as an aid for important decision-making within educational institutions. In health care delivery on the other hand, the emergence of QA is linked to the need for containing rising health care costs in the face of limited resources and to guaranteeing high quality patient care in a changing health care environment where the power relationship between doctors and patients is shifting towards patients. Although medical education can be regarded as a distinct entity in the health care industry, it still remains an inherent part of the health care delivery system. As a result, different strategies aimed at guaranteeing and assuring high standards of health care and education in many countries tend to overlap. This paper reflects on whether quality assurance in health care delivery and medical education should be seen as separate entities.Keywords: quality assurance, health care, higher medical education

    Nanoparticles have belonged to various fields of biomedical research for quite some time. A promising site-directed application in the field of nanomedicine is drug targeting using magnetic nanoparticles which are directed at the target tissue by means of an external magnetic field. Materials most commonly used for magnetic drug delivery contain metal or metal oxide nanoparticles, such as superparamagnetic iron oxide nanoparticles (SPIONs). SPIONs consist of an iron oxide core, often coated with organic materials such as fatty acids, polysaccharides or polymers to improve colloidal stability and to prevent separation into particles and carrier medium [1]. In general, magnetite and maghemite particles are those most commonly used in medicine and are, as a rule, well-tolerated. The magnetic properties of SPIONs allow the remote control of their accumulation by means of an external magnetic field. Conjugation of SPIONs with drugs, in combination with an external magnetic field to target the nanoparticles (so-called "magnetic drug targeting", MDT), has additionally emerged as a promising strategy of drug delivery. Magnetic nanoparticle-based drug delivery is a sophisticated overall concept and a multitude of magnetic delivery vehicles have been developed. Targeting mechanism-exploiting, tumor-specific attributes are becoming more and more sophisticated. The same is true for controlled-release strategies for the diseased site. As it is nearly impossible to record every magnetic nanoparticle system developed so far, this review summarizes interesting approaches which have recently emerged in the field of targeted drug delivery for cancer therapy based on magnetic nanoparticles.

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

    Directory of Open Access Journals (Sweden)

    Maria Victoria Maliandi

    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.

    2015-05-20

    The fight against cancer comprises not only survival of the disease but also survival with the highest possible quality of life. Thus, supportive care in cancer aims at reducing physical and psycho-emotional symptom burden. Furthermore, supportive care in cancer includes self-management-support for patients and their families/caregivers. Due to high symptom prevalence and poor prognosis, lung cancer patients express more unmet supportive care needs than other patient populations with cancer. Interventions to meet these needs have been developed in the last decade. They involve new models of care that incorporate the role of a lung cancer nurse in comprehensive cancer centers and eHealth-systems to support lung cancer patients and their families/caregivers.

    Full Text Available Abstract Background A primary cause of high maternal mortality in Bangladesh is lack of access to professional delivery care. Examining the role of the family, particularly the husband, during pregnancy and childbirth is important to understanding women's access to and utilization of professional maternal health services that can prevent maternal mortality. This qualitative study examines husbands' involvement during childbirth and professional delivery care utilization in a rural sub-district of Netrokona district, Bangladesh. Methods Using purposive sampling, ten households utilizing a skilled attendant during the birth of the youngest child were selected and matched with ten households utilizing an untrained traditional birth attendant, or dhatri. Households were selected based on a set of inclusion criteria, such as approximate household income, ethnicity, and distance to the nearest hospital. Twenty semi-structured interviews were conducted in Bangla with husbands in these households in June 2010. Interviews were transcribed, translated into English, and analyzed using NVivo 9.0. Results By purposefully selecting households that differed on the type of provider utilized during delivery, common themes--high costs, poor transportation, and long distances to health facilities--were eliminated as sufficient barriers to the utilization of professional delivery care. Divergent themes, namely husbands' social support and perceived social norms, were identified as underlying factors associated with delivery care utilization. We found that husbands whose wives utilized professional delivery care provided emotional, instrumental and informational support to their wives during delivery and believed that medical intervention was necessary. By contrast, husbands whose wives utilized an untrained dhatri at home were uninvolved during delivery and believed childbirth should take place at home according to local traditions. Conclusions This study provides

    The efficacy of cancer drugs is often limited because only a small fraction of the administered dose accumulates in tumors. Here we report an injectable nanoparticle generator (iNPG) that overcomes multiple biological barriers to cancer drug delivery. The iNPG is a discoidal micrometer-sized particle that can be loaded with chemotherapeutics. We conjugate doxorubicin to poly(L-glutamic acid) by means of a pH-sensitive cleavable linker, and load the polymeric drug (pDox) into iNPG to assemble iNPG-pDox. Once released from iNPG, pDox spontaneously forms nanometer-sized particles in aqueous solution. Intravenously injected iNPG-pDox accumulates at tumors due to natural tropism and enhanced vascular dynamics and releases pDox nanoparticles that are internalized by tumor cells. Intracellularly, pDox nanoparticles are transported to the perinuclear region and cleaved into Dox, thereby avoiding excretion by drug efflux pumps. Compared to its individual components or current therapeutic formulations, iNPG-pDox shows enhanced efficacy in MDA-MB-231 and 4T1 mouse models of metastatic breast cancer, including functional cures in 40-50% of treated mice.

    The development of a recommendation was intended for the follow-up of breast cancer patients treated with curative intent in Hungary. Follow-up includes the permanent contact with and health education of the patient, the surveillance and control of the adverse effects of oncological therapies or radiotherapy, the screening of metachron cancers, and the comprehensive (physical, psychological and social) rehabilitation of the patient. The early detection of local/regional tumor relapse is essential with careful follow-up, but there is no need for screening of distant metastases by means of imaging studies or tumor marker tests. If adjuvant endocrine therapy is needed, optimal adherence should be ensured with supportive therapy. In rare cases, special issues such as breast cancer risk/genetic mutation, pregnancy are raised, which should be thoughtfully discussed in view of recent advances in oncology. Follow-up is generally practised by the oncologist, however, in some cases the social worker, the physiotherapist, the psychooncologist, or in special cases, the lymphoedema expert is to be involved. The follow-up approach should be comprehensive and holistic. PMID:27579724

  6. 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.

    Recent studies indicate the critical role of tumour associated macrophages, tumour associated neutrophils, dendritic cells, T lymphocytes, and natural killer cells in tumourigenesis. These cells can have a significant impact on the tumour microenvironment via their production of cytokines and chemokines. Additionally, products secreted from all these cells have defined specific roles in regulating tumour cell proliferation, angiogenesis, and metastasis. They act in a protumour capacity in vivo as evidenced by the recent studies indicating that macrophages, T cells, and neutrophils may be manipulated to exhibit cytotoxic activity against tumours. Therefore therapy targeting these cells may be promising, or they may constitute drug or anticancer particles delivery systems to the tumours. Herein, we discussed all these possibilities that may be used in cancer treatment. PMID:27212807

    A targeted delivery system based on the polymeric nanoparticles as a drug carrier represents a marvelous avenue for cancer therapy. The pivotal characteristics of this system include biodegradability, biocompatibility, non-toxicity, prolonged circulation and a wide payload spectrum of a therapeutic agent. Other outstanding features are their distinctive size and shape properties for tissue penetration via an active and passive targeting, specific cellular/subcellular trafficking pathways and facile control of cargo release by sophisticated material engineering. In this review, the current implications of encapsulation of anticancer agents within polyhydroxyalkanoates, poly-(lactic-co-glycolic acid) and cyclodextrin based nanoparticles to precisely target the tumor site, i.e., cell, tissue and organ are highlighted. Furthermore, the promising perspectives in this emerging field are discussed. PMID:26706565

    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.

    Since ancient times, chemopreventive agents have been used to treat/prevent several diseases including cancer. They are found to elicit a spectrum of potent responses including anti-inflammatory, antioxidant, antiproliferative, anticarcinogenic, and antiangiogenic activity in various cell cultures and some animal studies. Research over the past 4 decades has shown that chemopreventives affect a number of proteins involved in various molecular pathways that regulate inflammatory and carcinogenic responses in a cell. Various enzymes, transcription factors, receptors, and adhesion proteins are also affected by chemopreventives. Although, these natural compounds have shown significant efficacy in cell culture studies, they elicited limited efficacy in various clinical studies. Their introduction into the clinical setting is hindered largely by their poor solubility, rapid metabolism, or a combination of both, ultimately resulting in poor bioavailability upon oral administration. Therefore, to circumvent these limitations and to ease their transition to clinics, alternate strategies should be explored. Drug delivery systems such as nanoparticles, liposomes, microemulsions, and polymeric implantable devices are emerging as one of the viable alternatives that have been shown to deliver therapeutic concentrations of various potent chemopreventives such as curcumin, ellagic acid, green tea polyphenols, and resveratrol into the systemic circulation. In this review article, we have attempted to provide a comprehensive outlook for these delivery approaches, using curcumin as a model agent, and discussed future strategies to enable the introduction of these highly potent chemopreventives into a physician's armamentarium.

    2004-01-01

    Latina mothers in the United States enjoy surprisingly favorable birth outcomes despite their social disadvantages. This “Latina paradox” is particularly evident among Mexican-born women. The social and cultural factors that contribute to this paradox are maintained by community networks—informal systems of prenatal care that are composed of family, friends, community members, and lay health workers. This informal system confers protective factors that provide a behavioral context for healthy births. US-born Latinas are losing this protection, although it could be maintained with the support of community-based informal care systems. We recommend steps to harness the benefits of informal systems of prenatal care in Latino communities to meet the increasing needs of pregnant Latina women. PMID:15569952

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.

    2009-06-01

    This paper addresses a pharmacy delivery design problem with two types of human resources: pharmacy assistants and transporters within a hospital. Each medical unit of the hospital has a mobile medicine closet which is conveyed each week by transporters to the central pharmacy for inventory assessment and refill by assistants. Transportation is carried out by foot, by tractor or by truck depending on the location. The problem consists in creating a transportation and supply planning for each day of the week in order to balance workloads for both transporters and assistants while ensuring the availability of medicine to each medical service. A two-step approach using mixed-integer linear programming formulation is proposed to determine a near optimal schedule. Numerical results are given to assess its efficiency. The proposed approach is then combined with a simulation model to redesign the delivery process of the pharmacy department of a French university teaching hospital. Methodology of this real-life reengineering study is presented and discussed. PMID:19469456

    In health care, as in much of the public sphere, the voluntary sector is playing an increasingly large role in the funding, provision and delivery of services and nowhere is this more apparent than in cancer care. Simultaneously the growth of privatisation, marketisation and consumerism has engendered a rise in the promotion of 'user involvement' in health care. These changes in the organisation and delivery of health care, in part inspired by the 'Third Way' and the promotion of public and citizen participation, are particularly apparent in the British National Health Service. This paper presents initial findings from a three-year study of user involvement in cancer services. Using both case study and survey data, we explore the variation in the definition, aims, usefulness and mechanisms for involving users in the evaluation and development of cancer services across three Health Authorities in South West England. The findings have important implications for understanding shifts in power, autonomy and responsibility between patients, carers, clinicians and health service managers. The absence of any common definition of user involvement or its purpose underlines the limited trust between the different actors in the system and highlights the potentially negative impact of a Third Way health service.

    Progresses in cancer treatment transformed cancer into a chronic disease associated with growing nutritional problems. Poor nutritional status of cancer patients worsens morbidity, mortality, overall cost of care and decreases patients' quality of life, oncologic treatments tolerance and efficacy. These adverse effects lead to treatment modifications or interruptions, reducing the chances to control or cure cancer. Implementation of an interdisciplinary and longitudinal integration of nutritional care and nutritional information into cancer treatment (The OncoNut Program) could prevent or treat poor nutritional status and its adversely side effects.

    2016-07-01

    Five-year survival rates have improved over the past 40 years for nearly all types of cancer, partially thanks to early detection and prevention. Since patients typically present to their primary care physician with initial symptoms, it is vital for primary care physicians to accurately diagnose common cancers and to recognize unusual presentations of highly curable cancers such as Hodgkin lymphoma and testicular cancers, for which the 5-year overall survival rates are greater than 85%. This paper reviews these cancers and provides clinically relevant pearls from an oncologic perspective for physicians who are the first point of contact. PMID:27399864

    Patient navigation is an internationally utilized, culturally grounded, and multifaceted strategy to optimize patients' interface with the health-care team and system. The DuPage County Patient Navigation Collaborative (DPNC) is a campus-community partnership designed to improve access to care among uninsured breast and cervical cancer patients in DuPage County, IL. Importantly, the DPNC connects community-based social service delivery with the patient-centered medical home to achieve a community-nested patient-centered medical home model for cancer care. While the patient navigator experience has been qualitatively documented, the literature pertaining to patient navigation has largely focused on efficacy outcomes and program cost effectiveness. Here, we uniquely highlight stories of women enrolled in the DPNC, told from the perspective of patient navigators, to shed light on the myriad barriers that DPNC patients faced and document the strategies DPNC patient navigators implemented.

    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. PMID:26598947

The survey also collected information regarding pharmaceutical care consultation received by the patients and brief demographic data.Results: A total of 628 patients from 55 pharmacies completed the survey. The pilot study’s three-factor satisfaction structure was confirmed. Overall, satisfaction measures did not differ by demographics or medical condition, but there were strong and significant store-to-store differences and consultation practice advantages when pharmacists or pharmacists-plus-students participated, but not for consultations with students alone.Conclusion: Patient satisfaction can be reliably measured by surveys structured around pharmaceutical care activities. The introduction of pharmaceutical care in pharmacies improves patient satisfaction. Service gap details indicated that pharmacy managers need to pay closer attention to various consultative activities involving patients

    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

  1. Caring for cancer patients on non-specialist wards.

    LENUS (Irish Health Repository)

    Gill, Finola

    2012-02-01

    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.

    Unprecedented progress has been made in genomic personalized medicine in the last several years, allowing for more individualized healthcare assessments and recommendations than ever before. However, most of this progress in prostate cancer (PCa) care has focused on developing and selecting therapies for late-stage disease. To address this issue of limited focus, we propose a model for incorporating genomic-based personalized medicine into all levels of PCa care, from prevention and screening to diagnosis, and ultimately to the treatment of both early-stage and late-stage cancers. We have termed this strategy the "Pyramid Model" of personalized cancer care. In this perspective paper, our objective is to demonstrate the potential application of the Pyramid Model to PCa care. This proactive and comprehensive personalized cancer care approach has the potential to achieve three important medical goals: reducing mortality, improving quality of life and decreasing both individual and societal healthcare costs.

    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.

    2013-05-01

    As cancer care becomes increasingly complex, the ability to coordinate this care is more difficult for health care providers, patients and their caregivers alike. Despite the widely recognized need for improving continuity and coordination of care, the relationship of continuity of care with patient outcomes has yet to be elucidated. Our study's main finding is that the Continuity and Coordination subscale of the widely used Picker System of Ambulatory Cancer Care Survey is able to distinguish between lung cancer patients with unmet supportive care needs and those without. Specifically, this study shows a new association between this widely implemented continuity and coordination survey and the 'psychological needs' domain, as well as the 'health system and information' domains of supportive care needs. The finding provides support for the idea that interventions to improve continuity may impact tangible indicators of patient care such as supportive care needs being met. The study focuses attention on continuity of care as an important aspect of optimizing outcomes in cancer care. PMID:23274923

    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.

    A major barrier to successful integration of acute care into health systems is the lack of consensus on the essential components of emergency care within resource-limited environments. The 2013 African Federation of Emergency Medicine Consensus Conference was convened to address the growing need for practical solutions to further implementation of emergency care in sub-Saharan Africa. Over 40 participants from 15 countries participated in the working group that focused on emergency care delivery at health facilities. Using the well-established approach developed in the WHO's Monitoring Emergency Obstetric Care, the workgroup identified the essential services delivered-signal functions-associated with each emergency care sentinel condition. Levels of emergency care were assigned based on the expected capacity of the facility to perform signal functions, and the necessary human, equipment and infrastructure resources identified. These consensus-based recommendations provide the foundation for objective facility capacity assessment in developing emergency health systems that can bolster strategic planning as well as facilitate monitoring and evaluation of service delivery.

    Full Text Available This paper presents the implementation of a smart environment that employs Ambient Intelligence technologies in order to augment a typical hospital room with smart features that assist both patients and medical staff. In this environment various wireless and wired sensor technologies have been integrated, allowing the patient to control the environment and interact with the hospital facilities, while a clinically oriented interface allows for vital sign monitoring. The developed applications are presented both from a patient’s and a doctor’s perspective, offering different services depending on the user’s role. The results of the evaluation process illustrate the need for such a service, leading to important conclusions about the usefulness and crucial role of AmI in health care.

    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.

    To define a set of quality indicators that should be routinely measured and evaluated to confirm that the clinical outcome reaches the requested standards, Eusoma has organised a workshop during which twenty four experts from different disciplines have reviewed the international literature and selected the main process and outcome indicators available for quality assurance of breast cancer care. A review of the literature for evidence-based recommendations have been performed by the steering committee. The experts have identified the quality indicators also taking into account the usability and feasibility. For each of them it has been reported: definition, minimum and target standard, motivation for selection and level of evidence (graded according to AHRO). In overall 17 main quality indicators have been identified, respectively, 7 on diagnosis, 4 on surgery and loco-regional treatment, 2 on systemic treatment and 4 on staging, counselling, follow-up and rehabilitation. Breast Units in Europe are invited to comply with these indicators and monitor them during their periodic audit meetings. PMID:20675120

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. PMID:26248847

    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...

    Market transformations occurring within the health care industry require new patterns of organization and management to meet the increasing complexity of service delivery. A greater understanding of the innovation and entrepreneurial dynamic allows administrators, managers, and leaders to create a new vision of service delivery. Central management and leadership objectives include the development of service technologies that capitalize upon the inherent knowledge of workers to meet consumer needs. A strong sense of innovation and entrepreneurship leading to the introduction of new or improved nursing technologies is a primary component in the evolution of professional nursing practice for the 21st century.

    Little is known about health and social care provision for people with long-term care (LTC) needs under multiple insurances. The aim of this study is to compare the profile, case-mix, and service provision to older people at long-term care hospitals (LTCHs) covered by the national health insurance (NHI) with those of older people at long-term care facilities (LTCFs) covered by the public long-term care insurance (LTCI) in Korea. A national LTC survey using common functional measures and a case-mix classification system was conducted with a nationally representative sample of older people at LTCFs and LTCHs in 2013. The majority of older people in both settings were female and frail, with complex chronic diseases. About one fourth were a low-income population with Medical-Aid. The key functional status was similar between the two groups. As for case-mix, more than half of the LTCH population were categorized as having lower medical care needs, while more than one fourth of the LTCF residents had moderate or higher medical care needs. Those with high medical care needs at LTCFs were significantly more likely to be admitted to acute-care hospitals than their counterparts at LTCHs. The current delivery of institutional LTC under the two insurances in Korea is not coordinated well. It is necessary to redefine the roles of LTCHs and strengthen health care in LTCFs. A systems approach is critical to establish person-centered, integrated LTC delivery across different financial sources. PMID:26305121

Palliative care refers to the total care of a patient, regardless of his or her disease status, and aims to improve quality of life by controlling symptoms and alleviating physical, social, psychological, and spiritual suffering. Integrating palliative care into standard oncology practice for AYAs is therefore valuable, if not imperative, in improving their overall cancer experience. In this review, we aimed to describe the scope, benefits, and challenges of palliative care for AYA oncology patients. We provide a broad impression of the existing literature describing or investigating palliative care in this population. Put together, the evidence suggests that palliative care is not only needed, but can also be critically beneficial to patients, families, and health care professionals alike. As we increase public and professional awareness of the needs and applications of palliative care for AYA patients with cancer, we will ultimately enable better psychosocial outcomes of the AYA patients and their larger communities.Keywords: supportive care, end of life, psychosocial outcomes, psychosocial oncology, psychosocial needs, quality of life

    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. PMID:23170959

    The evolution of supportive care in lung cancer (LC) is the focus of this article, which aims to present an overall picture of the developments in the field, highlight milestones over the past four decades, and provide directions for future research and practice. Although in the 1970s this study was minimal, from the 1980s onwards, there was an expansion of the range of topics covered in the literature, reflecting the importance of supportive care to clinical practice. These areas include the identification of supportive care needs in LC, symptoms and symptom management, psychosocial aspects and coping with LC (including support of caregivers), quality of life issues and the development and testing of patient-reported outcomes, the option of best supportive care versus treatment, smoking cessation before and after diagnosis of LC, and service delivery models. This article celebrates the evolution of supportive LC care over the past 40 years alongside recognizing that more work needs to be done in the future and new research foci need to be developed to meet the current needs of patients with LC. The role and the continuous efforts of the International Association of the Study of Lung Cancer, including the sixteenth World Conference on Lung Cancer in 2015 to meet this goal, will be crucial and strategic in the future.

    Science.gov (United States)

    Wald, J. S.

    2014-01-01

    Summary Objectives Address current topics in consumer health informatics. Methods Literature review. Results Current health care delivery systems need to be more effective in the management of chronic conditions as the population turns older and experiences escalating chronic illness that threatens to consume more health care resources than countries can afford. Most health care systems are positioned poorly to accommodate this. Meanwhile, the availability of ever more powerful and cheaper information and communication technology, both for professionals and consumers, has raised the capacity to gather and process information, communicate more effectively, and monitor the quality of care processes. Conclusions Adapting health care systems to serve current and future needs requires new streams of data to enable better self-management, improve shared decision making, and provide more virtual care. Changes in reimbursement for health care services, increased adoption of relevant technologies, patient engagement, and calls for data transparency raise the importance of patient-generated health information, remote monitoring, non-visit based care, and other innovative care approaches that foster more frequent contact with patients and better management of chronic conditions.

    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

    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

    Many states in the United States, including Pennsylvania, have opted to rely on private managed care organizations to provide health insurance coverage for their Medicaid population in recent years. Geisinger Health System has been one such organization since 2013. Based on its existing care management model involving data-driven population management, advanced patient-centered medical homes, and targeted case management, Geisinger's Medicaid management efforts have been redesigned specifically to accommodate those with complex health care issues and social service needs to facilitate early intervention, effective and efficient care support, and ultimately, a positive impact on health care outcomes. An analysis of Geisinger's claims data suggests that during the first 19 months since beginning Medicaid member enrollment, Geisinger's Medicaid members, particularly those eligible for the supplemental security income benefits, have incurred lower inpatient, outpatient, and professional costs of care compared to expected levels. However, the total cost savings were partially offset by the higher prescription drug costs. These early data suggest that an integrated Medicaid care management effort may achieve significant cost of care savings. (Population Health Management 2016;19:257-263). PMID:26565693

    Context: Perceptions about low-value care (eg, medical tests and procedures that may be unnecessary and/or harmful) among clinicians with capitated salaries are unknown. Objective: Explore clinicians’ perceived use of and responsibility for reducing low-value care by focusing on barriers to use, awareness of the Choosing Wisely campaign, and response to reports of peer-comparison resource use and practice patterns. Methods: Electronic, cross-sectional survey, distributed in 2013, to 304 salaried primary care physicians and physician assistants at Group Health Cooperative. Main Outcome Measures: Attitudes, awareness, and barriers of low-value care strategies and initiatives. Results: A total of 189 clinicians responded (62% response rate). More than 90% believe cost is important to various stakeholders and believe it is fair to ask clinicians to be cost-conscious. Most found peer-comparison resource-use reports useful for understanding practice patterns and prompting peer discussions. Two-thirds of clinicians were aware of the Choosing Wisely campaign; among them, 97% considered it a legitimate information source. Although 88% reported being comfortable discussing low-value care with patients, 80% reported they would order tests or procedures when a patient insisted. As key barriers in reducing low-value care, clinicians identified time constraints (45%), overcoming patient preferences/values (44%), community standards (43%), fear of patients’ dissatisfaction (41%), patients’ knowledge about the harms of low-value care (38%), and availability of tools to support shared decision making (37%). Conclusions: Salaried clinicians are aware of rising health care costs and want to be stewards of limited health care resources. Evidence-based initiatives such as the Choosing Wisely campaign may help motivate clinicians to be conscientious stewards of limited health care resources. PMID:26562308

    2014-07-01

    All persons have a right to palliative care during cancer treatment and at the end-of-life. The World Health Organization (WHO) defines palliative care as a medical specialty that addresses physical, psychological, social, legal, and spiritual domains of care by an interdisciplinary team of professional and lay health care providers. Widespread adoption of this universal definition will aid policy development and educational initiatives on a national level. The need for palliative care is expanding due to the aging of the world's population and the increase in the rate of cancer in both developed and developing countries. However, in one third of the world there is no access to palliative care for persons with serious or terminal illness. Palliative care improves symptoms, most frequently pain, and improves quality of life for patients and their families, especially in the terminal disease phase. Accessibility to palliative care services, adequately trained health care professionals, availability of essential medicines, and gaps in education vary greatly throughout the world. Pain management is an integral concept in the practice of palliative care; however, opioiphobia, insufficient supply of opioids, and regulatory restrictions contribute to undue suffering for millions. Ongoing advocacy efforts call for increased awareness, palliative care integration with cancer care, and public and professional education. Enacting necessary change will require the engagement of health ministries and the recognition of the unique needs and resources of each country. The aim of this review is to examine progress in palliative care development and explore some of the barriers influencing cancer care across the globe. PMID:25841689

    Full Text Available To The Editor: There is an increasing need to incorporate the use of electronic medical records EMR in our healthcare delivery. The advancement in information technology and its impact in all sectors including healthcare has accelerated this need amidst the ever growing challenges facing healthcare today. These challenges include; reducing preventable errors, improving communication among health care providers and facilities, and controlling the cost of medical care. I may argue that employing an electronic medical record system may be the one solution that will addresses all of these issues. The literature shows that Innovations in electronic record keeping have dramatically improved communication and patient safety without increasing costs.

    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.

    Full Text Available Abstract Background The national Cancer Reform Strategy recommends delivering care closer to home whenever possible. Cancer drug treatment has traditionally been administered to patients in specialist hospital-based facilities. Technological developments mean that nowadays, most treatment can be delivered in the out-patient setting. Increasing demand, care quality improvements and patient choice have stimulated interest in delivering some treatment to patients in the community, however, formal evaluation of delivering cancer treatment in different community settings is lacking. This randomised trial compares delivery of cancer treatment in the hospital with delivery in two different community settings: the patient's home and general practice (GP surgeries. Methods/design Patients due to receive a minimum 12 week course of standard intravenous cancer treatment at two hospitals in the Anglia Cancer Network are randomised on a 1:1:1 basis to receive treatment in the hospital day unit (control arm, or their own home, or their choice of one of three neighbouring GP surgeries. Overall patient care, treatment prescribing and clinical review is undertaken according to standard local practice. All treatment is dispensed by the local hospital pharmacy and treatment is delivered by the hospital chemotherapy nurses. At four time points during the 12 week study period, information is collected from patients, nursing staff, primary and secondary care teams to address the primary end point, patient-perceived benefits (using the emotional function domain of the EORTC QLQC30 patient questionnaire, as well as secondary end points: patient satisfaction, safety and health economics.

    2011-05-01

    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

    2015-01-01

    Lung cancer is the leading cause of death due to malignancy. Although lung cancer mortality has been decreasing in recent years, it remains substantially higher than other causes of cancer death. Median survival for patients with locally advanced non-small cell lung cancer, defined as lung cancer involving regional lymph nodes, is estimated to be approximately 10 to 17 months, and median survival for patients with metastatic disease is only 6 to 9 months. In addition, patients with advanced lung cancer often experience debilitating symptoms and poor quality of life. Pain, dyspnea, and fatigue are most frequently reported and affect at least 65% of patients with advanced lung cancer. Given this burden of symptoms and high mortality, patients and their families facing a diagnosis of advanced lung cancer are in need of support. Palliative care, with its focus on addressing the emotional, physical, and spiritual sources of suffering utilizing the expertise of an interdisciplinary team, can provide this comprehensive support. This review describes the role of supportive and palliative care integrated into the treatment of patients with a diagnosis of advanced lung cancer with sections focused on the evaluation and treatment of pain and dyspnea, approaches to challenging communication tasks, and the support of caregivers who care for patients with advanced lung cancer.

    Supportive care is an essential component of anticancer treatment regardless of age or treatment intent. As the number of older adults with cancer increases, and supportive care strategies enable more patients to undergo treatment, greater numbers of older patients will become cancer survivors. These patients may have lingering adverse effects from treatment and will need continued supportive care interventions. Older adults with cancer benefit from geriatric assessment (GA)-guided supportive care interventions. This can occur at any stage across the cancer treatment continuum. As a GA commonly uncovers issues potentially unrelated to anticancer treatment, it could be argued that the assessment is essentially a supportive care strategy. Key aspects of a GA include identification of comorbidities, assessing for polypharmacy, screening for cognitive impairment and delirium, assessing functional status, and screening for psychosocial issues. Treatment-related issues of particular importance in older adults include recognition of increased bone marrow toxicity, management of nausea and vomiting, identification of anemia, and prevention of neurotoxicity. The role of physical therapy and cancer rehabilitation as a supportive care strategy in older adults is important regardless of treatment stage or intent. PMID:27342609

    2016-01-01

    Prostate cancer is one of the most common cancers diagnosed in men. Whilst treatments for early-stage disease are largely effective, current therapies for metastatic prostate cancer, particularly for bone metastasis, offer only a few months increased lifespan at best. Hence new treatments are urgently required. Small interfering RNA (siRNA) has been investigated for the treatment of prostate cancer where it can ‘silence’ specific cancer-related genes. However the clinical application of siRNA...

    Uninsured and underinsured near-elderly may not have timely investigation, diagnosis, or care of cancer. Prior studies suggest Medicare eligibility confers significant and substantial reductions in mortality and increases in health service utilization. We compared 2245 patients diagnosed with lung cancer at ages 64.5 to 65 years and 2512 patients aged 65 to 65.5 years, with 2492 patients aged 65.5 to 66 years (controls) in 2000 to 2005. Compared with controls, patients diagnosed with lung cancer before Medicare eligibility had no statistically significant differences in cancer stage, time to treatment, type of treatment, and survival. Study power was sufficient to exclude mortality reductions and health service utilization changes of the magnitude found in prior work, suggesting that typically, appropriate lung cancer care may be sought and delivered regardless of insurance status.

    Kathryn Schnippel

    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

    In the present study, we report the delivery of anti-cancer drug curcumin to cancer cells using mesoporous silica materials. A series of mesoporous silica material based drug delivery systems (S2, S4 and S6) were first designed and developed through the amine functionalization of KIT-6, MSU-2 and MCM-41 followed by the loading of curcumin. The curcumin loaded materials were characterized with several physico-chemical techniques and thoroughly screened on cancer cells to evaluate their in vitro drug delivery efficacy. All the curcumin loaded silica materials exhibited higher cellular uptake and inhibition of cancer cell viability compared to pristine curcumin. The effective internalization of curcumin in cancer cells through the mesoporous silica materials initiated the generation of intracellular reactive oxygen species and the down regulation of poly ADP ribose polymerase (PARP) enzyme levels compared to free curcumin leading to the activation of apoptosis. This study shows that the anti-cancer activity of curcumin can be potentiated by loading onto mesoporous silica materials. Therefore, we strongly believe that mesoporous silica based curcumin loaded drug delivery systems may have future potential applications for the treatment of cancers. PMID:26674254

    Radical pelvic surgery in gynecologic oncology patients poses a challenge to the surgeon and the ancillary team in charge of the peri-operative care. The high frequency of medical problems observed in this patient population, in conjunction with the stresses of radical surgery, necessitates careful monitoring of patients' medical status. A comprehensive team approach in the perioperative period is critical to patient care. Early intervention and anticipation of potential problems for the patient at risk in the postoperative period minimizes morbidity and mortality. This article will review the essentials of critical care as it relates to patients undergoing radical pelvic operations. PMID:10225307

    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.

    Halldórsdóttir, S; Hamrin, E

    1997-04-01

    The aim of this phenomenological study was to explore caring and uncaring encounters with nurses and other health professionals from the perspective of the person who has been diagnosed and treated for cancer. Through thematic analysis of in-depth dialogues with five women and four men in the remission or recovery phase of cancer, three major categories regarding caring and uncaring encounters were identified. The essential structure of a caring encounter was found to be threefold: 1. the nurse/health professional perceived as caring: an indispensable companion on the cancer trajectory; 2. the resulting mutual trust and caring connection; and 3. the perceived effect of the caring encounter: a sense of solidarity, empowerment, well-being, and healing. The essential structure of an uncaring encounter is also threefold: 1. the nurse/health professional perceived as uncaring: an unfortunate hindrance to the perception of well-being and healing; 2. the resulting sense of mistrust and disconnection; and 3. the perceived effect of the uncaring encounter: a sense of uneasiness, discouragement, and a sense of being broken down. The findings emphasize the primacy of competence in professional caring, as well as that of genuine concern, openness and a willingness to connect with others. The often devastating effects of uncaring encounters on the recipient of nursing and health care raises the question whether uncaring as an ethical and a professional problem should perhaps be dealt with as malpractice in nursing and health care.

    A handful of the many changes resulting from the Affordable Care Act underscore the need for a geographic understanding of existing and prospective member communities. Health exchanges require that health provider networks are geographically accessible to underserved populations, and nonprofit hospitals nationwide are required to conduct community health needs assessments every three years. Beyond these requirements, health care providers are using maps and spatial analysis to better address health outcomes that are related in complex ways to social and economic factors.Kaiser Permanente is applying geographic information systems, with spatial analytics and map-based visualizations, to data sourced from its electronic medical records and from publicly and commercially available datasets. The results are helping to shape an understanding of the health needs of Kaiser Permanente members in the context of their communities. This understanding is part of a strategy to inform partnerships and interventions in and beyond traditional care delivery settings. PMID:24694317

    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

    A number of key trends are emerging in long-term care related to financing, new models of service delivery, and shifts in consumer expectations and preferences. Taken together, changes occurring in these areas point to a rapidly transforming long-term care landscape. Financing responsibility is shifting away from the federal government to states, individuals, and their families; providers are integrating and managing acute and long-term care services and adding new services to the continuum of care; and consumers are thinking more seriously about how to plan and pay for their future care needs, as well as how to independently navigate the long-term care system.

    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.

    2016-01-01

    Multidrug resistance (MDR) to chemotherapy presents a major obstacle in the treatment of cancer patients, which directly affects the clinical success rate of cancer therapy. Current research aims to improve the efficiency of chemotherapy, whilst reducing toxicity to prolong the lives of cancer patients. As with good biocompatibility, high stability and drug release targeting properties, nanodrug delivery systems alter the mechanism by which drugs function to reverse MDR, via passive or active targeting, increasing drug accumulation in the tumor tissue or reducing drug elimination. Given the potential role of nanodrug delivery systems used in multidrug resistance, the present study summarizes the current knowledge on the properties of liposomes, lipid nanoparticles, polymeric micelles and mesoporous silica nanoparticles, together with their underlying mechanisms. The current review aims to provide a reliable basis and useful information for the development of new treatment strategies of multidrug resistance reversal using nanodrug delivery systems.

    1997-01-01

    This paper discusses some basic economic principles and concepts and how they relate to the analysis of dental care delivery. The fundamental theories of consumer behavior, profit maximization, information and transaction costs, and agency are considered. It is asserted that the information gap existing between patients and providers gives rise to a principal-agent problem, the operative element of this paper. The authors conclude that while under managed fee-for-service (MFFS) delivery systems, third-party administrators use financial, administrative, and utilization management tools to guide consumer and provider behavior, to reduce the size of the information gap, and achieve a more efficient allocation of resources, this does not occur under direct reimbursement (DR).

    The World Cancer Report, a 351 - page global report issued by International Agency for Research on Cancer (IARC) tells us that cancer rates are set to increase at an alarming rate globally (Stewart and Kleiues 2003). Cancer rates could increase by 50 % to 15 million new cases in the year 2020. This will be mainly due to steadily aging populations in both developed and developing countries and also to current trends in smoking prevalence and the growing adoption of unhealthy lifestyles. The report also reveals that cancer has emerged as a major public health problem in developing countries, matching its effect in industrialized nations. Healthy lifestyles and public health action by governments and health practitioners could stem this trend, and prevent as many as one third of cancers worldwide. In a developing country such as India there has been a steady increase in the Crude Incidence Rate (CIR) of all cancers affecting both men and women over the last 15 years. The increase reported by the cancer registries is nearly 12 per cent from 1985 to 2001, representing a 57 per cent rise in India's cancer burden. The total number of new cases, which stood at 5.3 lakhs Care lakh is 100,000 in 1985 has risen to over 8.3 lakhs today. The pattern of cancers has changed over the years, with a disturbing increase in cases that are linked to the use of tobacco. In 2003, there were 3.85 lakhs of cases coming under this category in comparison with 1.94 lakhs cases two decades ago. Lung cancer is now the second most common cancer among men. Earlier, it was in fifth place. Among women in urban areas, cancer of the uterine cervix had the highest incidence 15 years ago, but it has now been overtaken by breast cancer. In rural areas, cervical cancer remains the most common form of the disease (The Hindu 2004). PMID:15244530

    Full Text Available This study focused on the determination of the delivery of services of day care workers in the municipality of Sta. 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

    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.

    The determinants of maternal and child health have been the recurrent topics of study in developing countries. Using the Demographic and Health Survey (2010) of Colombia, this study aimed to identify the determinants for professional antenatal care and institutional delivery, taking into account the interdependence of these two decisions, which we consider using a bivariate probit model. This study found that when certain factors affecting both the decision to seek prenatal care and giving birth in a hospital are neglected, the results of the estimates are inefficient. Estimates show that the effects of education, parity, regional location and economic status on institutional delivery tend to be underestimated in a univariate probit model. The results indicate that economic status, level of education, parity and medical-insurance affiliation influenced the joint likelihood of accessing professional antenatal care and delivering in a health facility. An important finding is that mothers with a higher level of education are 9 percentage points more likely to access these two health services compared with mothers who are illiterate. Another observed finding is the regional disparities. The evidence indicates that mothers in the Pacific Region, the poorest region of Colombia, are 6 percentage points less likely to access such services. Thus, the results indicate that the Colombian health policy should emphasize increasing the level of schooling of mothers and establish health facilities in the poorest regions of the country to ensure that women in need are provided with social health insurance.

    MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression. Because of significant changes in their expression in cancer, miRNAs are believed to be key factors in cancer genetics and to have potential as anticancer drugs. However, the delivery of miRNAs is limited by many barriers, such as low cellular uptake, immunogenicity, renal clearance, degradation by nucleases, elimination by phagocytic immune cells, poor endosomal release, and untoward side effects. Nonviral delivery systems have been developed to overcome these obstacles. In this review, we provide insights into the development of non-viral synthetic miRNA vectors and the promise of miRNA-based anticancer therapies, including therapeutic applications of miRNAs, challenges of vector design to overcome the delivery obstacles, and the development of miRNA delivery systems for cancer therapy. Additionally, we highlight some representative examples that give a glimpse into the current trends into the design and application of efficient synthetic systems for miRNA delivery. Overall, a better understanding of the rational design of miRNA delivery systems will promote their translation into effective clinical treatments. PMID:25450259

    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.

    The synthesis of mesoporous silica nanoparticles (MSN) covalently encapsulating fluoresceine or a photosensitizer, functionalized with galactose on the surface is described. Confocal microscopy experiments demonstrated that the uptake of galactose-functionalized MSN by colorectal cancer cells was mediated by galactose receptors leading to the accumulation of the nanoparticles in the endosomal and lysosomal compartments. The MSN functionalized with a photosensitizer and galactose were loaded with the anti-cancer drug camptothecin. Those MSN combining drug delivery and photodynamic therapy were tested on three cancer cell lines and showed a dramatic enhancement of cancer cell death compared to separate treatments.

    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

    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.

    There is no logical, linear way to approach a future in which knowledge and technology explode and new opportunities go hand-in-hand with rapid obsolescence. Teams and task groups will replace the vertical command structures of the past, making teamwork, flexibility, and imagination more important that absolute knowledge. Maximum downward task delegation and decentralization will empower workers at all levels while challenging the assumptions of licensure. As the health-care organization grows more ephemeral, management will become an increasingly subtle art. Visionary skills are essential in a dynamic, rapidly changing society where the past is no longer a guide for the future. PMID:1958819

    In the last few years there has been an increase in the number of clinical nurse specialists (CNSs) working in cancer care throughout the UK. This paper examines the issues raised by the proliferation of site-specific cancer CNS posts, developed to give a 'nursing lead' for a particular tumour type. The issues common to all CNS posts are exacerbated when a number of specialists are involved in the cancer journey, causing potential fragmentation and confusion. Key issues need to be addressed if the role is to remain credible, and ensure clarity for patients and the multiprofessional team. These include role clarification, sensitive integration, interface with other cancer CNSs and the multiprofessional team, evaluation, cost, education and training, recruitment and succession planning and the 'career cul-de-sac'. Cancer nursing's response to these challenges will set the professional agenda for education, training and future models of service delivery. PMID:12849018

Early, systematic integration of palliative care into standard oncology practice represents a valuable, imperative approach to improving the overall cancer experience for adolescents and young adults (AYAs. The importance of competent, confident, and compassionate providers for AYAs warrants the development of effective educational strategies for teaching AYA palliative care.

    In order to optimize the delivery of multidisciplinary cancer care to veterans, our institution has developed a regional cancer center with a telemedical outreach program. The objectives of this report are to describe the organization and function of the telemedical cancer center and to report our early clinical results. The Veterans Affairs Health Care System is organized into a series of integrated service networks that serve veterans within different areas throughout the United States. Within Veterans Integrated Service Network 20 (Washington, Alaska, Idaho, Oregon) we have developed a regional cancer center with telemedicine links to four outlying facilities within the service area. The telemedical outreach effort functions through the use of a multidisciplinary telemedicine tumor board. The tumor board serves patients in outlying facilities by providing comprehensive, multidisciplinary consultation for the complete range of malignancies. For individuals who do require referral to the cancer center, the tumor board serves to coordinate the logistical and clinical details of the referral process. This program has been in existence for 1 year. During that time 85 patients have been evaluated in the telemedicine tumor board. Sixty-two percent of the patients were treated at their closest facility; 38% were referred to the cancer center for treatment and/or additional diagnostic studies. The patients' diagnoses included the entire clinical spectrum of malignant disease. Preliminary clinical results demonstrate the program is feasible and it improves access to multidisciplinary cancer care. Potential benefits include improved referral coordination and minimization of patient travel and treatment delays. PMID:12020412

    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. PMID:21519942

    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.

    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.

    In resource-poor countries, the high cost of user fees for deliveries limits access to skilled attendance, and contributes to maternal and neonatal mortality and the impoverishment of vulnerable households. A growing number of countries are experimenting with different approaches to tackling financial barriers to maternal health care. This paper describes an innovative scheme introduced in Ghana in 2003 to exempt all pregnant women from payments for delivery, in which public, mission and private providers could claim back lost user fee revenues, according to an agreed tariff. The paper presents part of the findings of an evaluation of the policy based on interviews with 65 key informants in the health system at national, regional, district and facility level, including policymakers, managers and providers. The exemption mechanism was well accepted and appropriate, but there were important problems with disbursing and sustaining the funding, and with budgeting and management. Staff workloads increased as more women attended, and levels of compensation for services and staff were important to the scheme's acceptance. At the end of 2005, a national health insurance scheme, intended to include full maternal health care cover, was starting up in Ghana, and it was not yet clear how the exemptions scheme would fit into it.

    The LIVESTRONG Centers of Excellence were funded to increase the effectiveness of survivorship care in oncology practice. This study describes the ongoing process of adopting and implementing survivorship care using the framework of the diffusion of innovation theory of change. Primary data collection included telephone interviews with 39 members from the eight centers and site visits. Organizational characteristics, overall progress, and challenges for implementation were collected from proposals and annual reports. Creating an awareness of cancer survivorship care was a major accomplishment (relative advantage). Adoption depended on the fit within the cancer center (compatibility), and changed over time based on trial and error (trialability). Implementing survivorship care within the existing culture of oncology and breaking down resistance to change was a lengthy process (complexity). Survivorship care became sustainable as it became reimbursed, and more new patients were seen (observability). Innovators and early adopters were crucial to success. Diffusion of innovation theory can provide a strategy to evaluate adoption and implementation of cancer survivorship programs into clinical practice. PMID:24073165

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

    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...

    2016-08-01

    Exosomes and ferritin: Two biomacromolecules from our human bodies both draw increasing interest for advanced drug delivery due to their endogenous origin and their morphology, the cage-like structures. They possess perfect naturally designed structures for loading and shielding of cargo. Their intrinsic biological functions enable a natural delivery of the load and specific targeting. More and more evidences point towards the evolution of a new era of drug delivery strategies with exosomes and ferritin, even for potential personalized therapy. This review focuses on the advantages as well as limits of exosomes and ferritin as endogenous carriers for cancer therapy. We compare their structure-specific cargo loading and their intrinsic cancer-related biological functions. Remaining challenges and promising perspectives for future development to use these two endogenous agents are discussed. PMID:27157249

    Single drug therapy that leads to the multidrug resistance of cancer cells and severe side-effect is a thing of the past. Combination therapies that affect multiple signaling pathways have been the focus of recent active research. Due to the successful development of prodrug-based nano-drug delivery systems (P-N-DDSs), their use has been extended to combination therapy as drug delivery platforms. In this review, we focus specifically on the P-N-DDSs in the field of combination therapy including the combinations of prodrugs with different chemotherapeutic agents, other therapeutic agents, nucleic acid or the combination of different types of therapy (e.g. chemotherapy and phototherapy). The relevant examples of prodrug-based nanoparticulate drug delivery strategy in combination cancer therapy from the recent literature are discussed to demonstrate the feasibilities of relevant technology.

    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.

  11. Development and characterization of multifunctional nanoparticles for drug delivery to cancer cells

    Science.gov (United States)

    Nahire, Rahul Rajaram

    Lipid and polymeric nanoparticles, although proven to be effective drug delivery systems compared to free drugs, have shown considerable limitations pertaining to their uptake and release at tumor sites. Spatial and temporal control over the delivery of anticancer drugs has always been challenge to drug delivery scientists. Here, we have developed and characterized multifunctional nanoparticles (liposomes and polymersomes) which are targeted specifically to cancer cells, and release their contents with tumor specific internal triggers. To enable these nanoparticles to be tracked in blood circulation, we have imparted them with echogenic characteristic. Echogenicity of nanoparticles is evaluated using ultrasound scattering and imaging experiments. Nanoparticles demonstrated effective release with internal triggers such as elevated levels of MMP-9 enzyme found in the extracellular matrix of tumor cells, decreased pH of lysosome, and differential concentration of reducing agents in cytosol of cancer cells. We have also successfully demonstrated the sensitivity of these particles towards ultrasound to further enhance the release with internal triggers. To ensure the selective uptake by folate receptor- overexpressing cancer cells, we decorated these nanoparticles with folic acid on their surface. Fluorescence microscopic images showed significantly higher uptake of folate-targeted nanoparticles by MCF-7 (breast cancer) and PANC-1 (pancreatic cancer) cells compared to particles without any targeting ligand on their surface. To demonstrate the effectiveness of these nanoparticles to carry the drugs inside and kill cancer cells, we encapsulated doxorubicin and/or gemcitabine employing the pH gradient method. Drug loaded nanoparticles showed significantly higher killing of the cancer cells compared to their non-targeted counterparts and free drugs. With further development, these nanoparticles certainly have potential to be used as a multifunctional nanocarriers for image

    Full Text Available Aim: Advanced cancer, irrespective of the site of the cancer, is characterized by a number of associated symptoms that impair the quality of life of patients. The management of these symptoms guides palliative care. The present study aims to describe the symptoms and appropriate palliation provided in patients with advanced cancer in a tertiary care hospital in Uttarakhand. Methods: This was an observational study. A total of 100 patients with advanced cancer were included in the study. The data obtained from the patients included symptoms reported by the patients, currently prescribed treatments and the site of cancer. Results: The average number of symptoms reported per patient was 5.33 ± 0.67 (mean ± SE. The most common symptoms were pain, weakness/fatigue, anorexia, insomnia, nausea/vomiting, dyspnea, constipation and cough. Polypharmacy was frequent. Patients consumed approximately 8.7 ± 0.38 (mean ± SE drugs on average during the 2-month period of follow-up. Conclusion: The result gives insight into the varied symptomatology of patients with advanced cancer. Polypharmacy was quite common in patients with advanced cancer, predisposing them to complicated drug interactions and adverse drug reactions.

    Patients in specific vulnerable population groups suffer disproportionately from cancer. The elimination of cancer disparities is critically important for lessening the burden of cancer. The Patient Protection and Affordable Care Act provides both opportunities and challenges for addressing cancer care disparities and access to care. The American Society of Clinical Oncology (ASCO) advocates for policies that ensure access to cancer care for the underserved. Such policies include insurance reform and the reduction of economic barriers to quality health care. Building on ASCO's prior statement on disparities in cancer care (2009), this article summarizes elements of the health care law that are relevant to cancer disparities and provides recommendations for addressing major provisions in the law. It outlines specific strategies to address insurance reform, access to care, quality of care, prevention and wellness, research on health care disparities, and diversity in the health care workforce. ASCO is committed to leading efforts toward the improvement of cancer care among the most vulnerable patients. PMID:21810680

  15. Cancer survivors and their partners: the assessment of unmet supportive care needs

    International Nuclear Information System (INIS)

    Our understanding of unmet supportive care needs of cancer survivors and their partners is limited. Most studies have focused on needs of patients undergoing treatment and on Quality of life or patient satisfaction. For the purpose of this research, cancer survivors are defined as persons who received a cancer diagnosis at least one year previously and are disease free. The aim of this study is to develop measures to assess unmet needs in survivors and their partners. After developing the questionnaire items it was piloted for validity in a wide sample of cancer patients from the radiation oncology department. 105 patients, all women, 101 with breast cancer and 40 partners participated. Psychological morbidity of depression and anxiety was recorded and was low. Quality of life for both survivors and partners was close to the US population mean. For patients top 4 unmet needs was 1. Anxiety about cancer returning (35%), current information (21%), understandable information (28%), ongoing case manager (25%). Unmet needs for partners were 1. Need to know all the doctors were communication (3.2%), need for local health services (2.8%), current information (2.1%) and help with managing concerns about the cancer returning (2.1%). 73% of partners reported at least one positive outcome from their partner's experience, significantly more than the survivors. In conclusion, interim analysis of the questionnaire reveals validity. Survivors report ongoing high levels of unmet needs 3-9 years after cancer diagnosis ( 30%). Less than 4% of partners report such unmet needs. There is significant correlation between needs of partners and survivors, many of which relate to issues of ongoing support and information delivery

    To investigate health professionals' perspectives about factors that impede or facilitate cancer care for Indigenous people. Semi-structured interviews with 22 health professionals involved in Indigenous cancer care. Data were interpreted using an inductive thematic analysis approach. Participants presented their perspectives on a number of barriers and enablers to Indigenous cancer care. Barriers were related to challenges with communication, the health system and coordination of care, issues around individual and community priorities and views of cancer treatment and health professional judgement. Enablers to cancer care were related to the importance of trust and rapport as well as health care system and support factors. The findings highlighted the need for recording of Indigenous status in medical records and a coordinated approach to the provision of evidence-based and culturally appropriate cancer care. This could go some way to improving Indigenous patient's engagement with tertiary cancer care services. PMID:26918690

    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. PMID:25113773

    Full Text Available Abstract Background While many factors can influence the way that cancer care is delivered, including the way that evidence is packaged and disseminated, little research has evaluated how health care professionals who manage cancer patients seek and use this information to identify whether and how this could be supported. Through interviews we identified that general surgeons experience challenges in coordinating care for complex cancer patients whose management is not easily addressed by guidelines, and conducted a population-based survey of general surgeon information needs and information seeking practices to extend these findings. Methods General surgeons with privileges at acute care hospitals in Ontario, Canada were mailed a questionnaire to solicit information needs (task, importance, information seeking (source, frequency of and reasons for use, key challenges and suggested solutions. Non-responders received up to three reminder packages. Significant differences among sub-groups (age, setting were examined statistically (Kruskal Wallis, Mann Whitney, Chi Square. Standard qualitative methods were used to thematically analyze open-ended responses. Results The response rate was 44.2% (170/385 representing all 14 health regions. System resource constraints (60.4%, comorbidities (56.4% and physiologic factors (51.8% were top-ranked issues creating information needs. Local surgical colleagues (84.6%, other local colleagues (82.2% and the Internet (81.1% were top-ranked sources of information, primarily due to familiarity and speed of access. No resources were considered to be highly applicable to patient care. Challenges were related to limitations in diagnostics and staging, operative resources, and systems to support multidisciplinary care, together accounting for 76.0% of all reported issues. Findings did not differ significantly by surgeon age or setting of care. Conclusion General surgeons appear to use a wide range of information

    Objectives Four antenatal visits, delivery in a health facility, and three postnatal visits are the World Health Organization recommendations for women to optimize maternal health outcomes. This study examines maternal compliance with the full recommended maternal health visits in rural Tanzania with the goal of illuminating interventions to reduce inequalities in maternal health. Methods Analysis included 907 women who had given birth within two years preceding a survey of women of reproductive age. Multinomial logistic regression was used to assess the influence of maternal, household, and community-level characteristics on four alternative classes defining relative compliance with optimal configuration of maternal health care seeking behavior. Results Parity, wealth index, timeliness of ANC initiation, nearest health facility type, religion, and district of residence were significant predictors of maternal health care seeking when adjusted for other factors. Multiparous women compared to primiparous were less likely to seek care at the high level [RRR 0.16, 95 % confidence interval (CI) 0.06-0.46], at the mid-level (RRR 0.22, 95 % CI 0.09-0.58), and the mid-low level (RRR 0.27, 95 % CI 0.09-0.80). Women in the highest wealth index compared to those in the poorest group were almost three times more likely to seek the highest two levels of care versus the lowest level (high RRR 2.92, 95 % CI 1.27-6.71, mid-level RRR 2.71, 95 % 1.31-5.62). Conclusion Results suggest that efforts to improve the overall impact of services on the continuum of care in rural Tanzania would derive particular benefit from strategies that improve maternal health coverage among multiparous and low socioeconomic status women.

    Among all cancers, lung cancer is the major cause of deaths. Lung cancer can be categorized into two classes for prognostic and treatment purposes: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Both categories of cancer are resistant to certain drugs. Various mechanisms behind drug resistance are over-expression of superficial membrane proteins [glycoprotein (P-gp)], lung resistance-associated proteins, aberration of the intracellular enzyme system, enhancement of the cell repair system and deregulation of cell apoptosis. Structure-performance relationships and chemical compatibility are consequently major fundamentals in surfactant-based formulations, with the intention that a great deal investigation is committed to this region. With the purpose to understand the potential of P-gp in transportation of anti-tumor drugs to cancer cells with much effectiveness and specificity, several surfactant-based delivery systems have been developed which may include microspheres, nanosized drug carriers (nanoparticles, nanoemulsions, stealth liposomes, nanogels, polymer-drug conjugates), novel powders, hydrogels and mixed micellar systems intended for systemic and/or localized delivery.

    Extracellular vesicles (EVs) are different types of membrane-derived vesicles that originate from the endosomal pathway or the plasma membrane. These vesicles are used as "carriers" in intercellular communication, and are responsible for the transfer of biological cargo (lipids, proteins, RNA species, and DNA) between different cells. Despite the shortcomings in our knowledge of EV biology, attempts to employ EVs as natural delivery tools for therapeutic purposes have been partly successful in different settings. In this review, we highlight this unique potential of EVs, and discuss previous examples and future scenarios. PMID:26412464

    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

  7. Chemosensitization of cancer cells by siRNA using targeted nanogel delivery

    International Nuclear Information System (INIS)

    Chemoresistance is a major obstacle in cancer treatment. Targeted therapies that enhance cancer cell sensitivity to chemotherapeutic agents have the potential to increase drug efficacy while reducing toxic effects on untargeted cells. Targeted cancer therapy by RNA interference (RNAi) is a relatively new approach that can be used to reversibly silence genes in vivo by selectively targeting genes such as the epidermal growth factor receptor (EGFR), which has been shown to increase the sensitivity of cancer cells to taxane chemotherapy. However, delivery represents the main hurdle for the broad development of RNAi therapeutics. We report here the use of core/shell hydrogel nanoparticles (nanogels) functionalized with peptides that specially target the EphA2 receptor to deliver small interfering RNAs (siRNAs) targeting EGFR. Expression of EGFR was determined by immunoblotting, and the effect of decreased EGFR expression on chemosensitization of ovarian cancer cells after siRNA delivery was investigated. Treatment of EphA2 positive Hey cells with siRNA-loaded, peptide-targeted nanogels decreased EGFR expression levels and significantly increased the sensitivity of this cell line to docetaxel (P < 0.05). Nanogel treatment of SK-OV-3 cells, which are negative for EphA2 expression, failed to reduce EGFR levels and did not increase docetaxel sensitivity (P > 0.05). This study suggests that targeted delivery of siRNAs by nanogels may be a promising strategy to increase the efficacy of chemotherapy drugs for the treatment of ovarian cancer. In addition, EphA2 is a viable target for therapeutic delivery, and the siRNAs are effectively protected by the nanogel carrier, overcoming the poor stability and uptake that has hindered clinical advancement of therapeutic siRNAs

    2015-07-01

    In 2001, the Society of Critical Care Medicine published practice model guidelines that focused on the delivery of critical care and the roles of different ICU team members. An exhaustive review of the additional literature published since the last guideline has demonstrated that both the structure and process of care in the ICU are important for achieving optimal patient outcomes. Since the publication of the original guideline, several authorities have recognized that improvements in the processes of care, ICU structure, and the use of quality improvement science methodologies can beneficially impact patient outcomes and reduce costs. Herein, we summarize findings of the American College of Critical Care Medicine Task Force on Models of Critical Care: 1) An intensivist-led, high-performing, multidisciplinary team dedicated to the ICU is an integral part of effective care delivery; 2) Process improvement is the backbone of achieving high-quality ICU outcomes; 3) Standardized protocols including care bundles and order sets to facilitate measurable processes and outcomes should be used and further developed in the ICU setting; and 4) Institutional support for comprehensive quality improvement programs as well as tele-ICU programs should be provided.

    Background India aims to achieve universal access to institutional delivery. We undertook this study to estimate the universality of institutional delivery care for pregnant women in Haryana state in India. To assess the coverage of institutional delivery, we analyze service coverage (coverage of public sector institutional delivery), population coverage (coverage among different districts and wealth quintiles of the population) and financial risk protection (catastrophic health expenditure and impoverishment as a result of out-of-pocket expenditure for delivery). Methods We analyzed cross-sectional data collected from a randomly selected sample of 12,191 women who had delivered a child in the last one year from the date of data collection in Haryana state. Five indicators were calculated to evaluate coverage and financial risk protection for institutional delivery—proportion of public sector deliveries, out-of-pocket expenditure, percentage of women who incurred no expenses, prevalence of catastrophic expenditure for institutional delivery and incidence of impoverishment due to out-of-pocket expenditure for delivery. These indicators were calculated for the public and private sectors for 5 wealth quintiles and 21 districts of the state. Results The coverage of institutional delivery in Haryana state was 82%, of which 65% took place in public sector facilities. Approximately 63% of the women reported no expenditure on delivery in the public sector. The mean out-of-pocket expenditures for delivery in the public and private sectors in Haryana were INR 771 (USD 14.2) and INR 12,479 (USD 229), respectively, which were catastrophic for 1.6% and 22% of households, respectively. Conclusion Our findings suggest that there is considerably high coverage of institutional delivery care in Haryana state, with significant financial risk protection in the public sector. However, coverage and financial risk protection for institutional delivery vary substantially across

    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. PMID:26978341

    2001-01-01

    This article has summarized research and policy activities undertaken in Washington State over the past several years to identify the key problems that result in poor quality and excessive disability among injured workers, and the types of system and delivery changes that could best address these problems in order to improve the quality of occupational health care provided through the workers' compensation system. Our investigations have consistently pointed to the lack of coordination and integration of occupational health services as having major adverse effects on quality and health outcomes for workers' compensation. The Managed Care Pilot Project, a delivery system intervention, focused on making changes in how care is organized and delivered to injured workers. That project demonstrated robust improvements in disability reduction; however, worker satisfaction suffered. Our current quality improvement initiative, developed through the Occupational Health Services Project, synthesizes what was learned from the MCP and other pilot studies to make delivery system improvements. This initiative seeks to develop provider incentives and clinical management processes that will improve outcomes and reduce the burden of disability on injured workers. Fundamental to this approach are simultaneously preserving workers' right to choose their own physician and maintaining flexibility in the provision of individualized care based on clinical need and progress. The OHS project then will be a "real world" test to determine if aligning provider incentives and giving physicians the tools they need to optimize occupational health delivery can demonstrate sustainable reduction in disability and improvements in patient and employer satisfaction. Critical to the success of this initiative will be our ability to: (1) enhance the occupational health care management skills and expertise of physicians who treat injured workers by establishing community-based Centers of Occupational

    Full Text Available Abstract A tremendous improvement in every aspect of breast cancer management has occurred in the last two decades. Surgeons, once solely interested in the extipartion of the primary tumor, are now faced with the need to incorporate a great deal of information, and to manage increasingly complex tasks. As a comprehensive assessment of all aspects of breast cancer care is beyond the scope of the present paper, the current review will point out some of these innovations, evidence some controversies, and stress the need for the surgeon to specialize in the various aspects of treatment and to be integrated into the multisciplinary breast unit team.

    Full Text Available INTRODUCTION: Patients with heart failure have a significant symptom burden and other palliative care needs often over a longer period than patients with cancer. It is acknowledged that this need may be unmet but by how much has not been quantified in primary care data at the population level. METHODS: This was the first use of Clinical Practice Research Datalink, the world's largest primary care database to explore recognition of the need for palliative care. Heart failure and cancer patients who had died in 2009 aged 18 or over and had at least one year of primary care records were identified. A palliative approach to care among patients with heart failure was compared to that among patients with cancer using entry onto a palliative care register as a marker for a palliative approach to care. RESULTS: Among patients with heart failure, 7% (234/3 122 were entered on the palliative care register compared to 48% (3 669/7 608 of cancer patients. Of heart failure patients on the palliative care register, 29% (69/234 were entered onto the register within a week of their death. CONCLUSIONS: This confirms that the stark inequity in recognition of palliative care needs for people with heart failure in a large primary care dataset. We recommend a move away from prognosis based criteria for palliative care towards a patient centred approach, with assessment of and attention to palliative needs including advance care planning throughout the disease trajectory.

    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

    Participation by women in screening programs for cervical cancer is far from optimal, and many lives are lost because of this. Cervical cancer is common, and is easily detected and treated. It has a good prognosis for cure if detected early in its course. Effective screening has been shown to have a major role in decreasing the morbidity and mortality associated with cervical cancer. Therefore, there is a need for increased public health education and availability of screening programs for women. It is particularly important that public health efforts reach women in the lower socioeconomic groups who are less apt to exhibit health promotive behaviors. Women of Latin American heritage are at particularly high risk because of cultural barriers to the discussion of sexual practices. Until public health interventions are more successful, cervical cancer will continue to pose a major threat to women who are either too embarrassed or too misinformed to understand that prevention is an integral part of women's health care. Nurses view patients in a holistic way. It is this philosophy of care that offers women who are diagnosed with cervical cancer a means to adapt successfully to the psychologic and physiologic stresses associated with the diagnosis. Nurses need to recognize this strength and to offer holistic approaches to women in crisis. No two patients deal with a diagnosis of cancer in the same manner. A major challenge to nurses across a hospital community continuum is to provide comprehensive psychologic and physiologic assessment of a women's response to a diagnosis of cervical cancer and to provide effective and holistic intervention when necessary.

    Challenged by demands to reduce costs and improve service delivery, the U.S. health care system requires transformational change. Health systems innovation is defined broadly as novel ideas, products, services, and processes-including new ways to promote healthy behaviors and better integrate health services with public health and other social services-which achieve better health outcomes and/or patient experience at equal or lower cost. Academic health centers (AHCs) have an opportunity to focus their considerable influence and expertise on health systems innovation to create new approaches to service delivery and to nurture leaders of transformation. AHCs have traditionally used their promotions criteria to signal their values; creating a health systems innovator promotion track could be a critical step towards creating opportunities for innovators in academic medicine. In this Perspective, the authors review publicly available promotions materials at top-ranked medical schools and find that while criteria for advancement increasingly recognize systems innovation, there is a lack of specificity on metrics beyond the traditional yardstick of peer-reviewed publications. In addition to new promotions pathways and alternative evidence for the impact of scholarship, other approaches to fostering health systems innovation at AHCs include more robust funding for career development in health systems innovation, new curricula to enable trainees to develop skills in health systems innovation, and new ways for innovators to disseminate their work. AHCs that foster health systems innovation could meet a critical need to contribute both to the sustainability of our health care system and to AHCs' continued leadership role within it.

  20. Clinical care and technical recommendations for 90yttrium microsphere treatment of liver cancer

    International Nuclear Information System (INIS)

    Selective internal radiation therapy (SIRT) with 90yttrium microspheres is a relatively new clinical modality for treating non-resectable malignant liver tumours. This interventional radiology technique employs percutaneous microcatheterisation of the hepatic arterial vasculature to selectively deliver radioembolic microspheres into neoplastic tissue. SIRT results in measurable tumour responses or delayed disease progression in the majority of eligible patients with hepatocellular carcinoma or hepatic metastases arising from colorectal cancer. It has also been successfully used as palliative therapy for non-colorectal malignancies metastatic to the liver. Although most adverse events are mild and transient, SIRT also carries some risks for serious and – rarely – fatal outcomes. In particular, entry of microspheres into non-target vessels may result in radiation-induced tissue damage, such as severe gastric ulceration or radiation cholecystitis. Radiation-induced liver disease poses another significant risk. By careful case selection, considered dose calculation and meticulous angiographic technique, it is possible to minimise the incidence of such complications to less than 10% of all treatments. As the number of physicians employing SIRT expands, there is an increasing need to consolidate clinical experience and expertise to optimise patient outcomes. Authored by a panel of clinicians experienced in treating liver tumours via SIRT, this paper collates experience in vessel mapping, embolisation, dosimetry, microsphere delivery and minimisation of non-target delivery. In addition to these clinical recommendations, the authors propose institutional criteria for introducing SIRT at new centres and for incorporating the technique into multidisciplinary care plans for patients with hepatic neoplasms.

    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.

    A genetically engineered apoferritin variant consisting of 24 heavy-chain subunits (HFn) was produced to achieve a cumulative delivery of an antitumor drug, which exerts its cytotoxic action by targeting the DNA at the nucleus of human cancer cells with subcellular precision. The rationale of our approach is based on exploiting the natural arsenal of defense of cancer cells to stimulate them to recruit large amounts of HFn nanoparticles loaded with doxorubicin inside their nucleus in response to a DNA damage, which leads to a programmed cell death. After demonstrating the selectivity of HFn for representative cancer cells compared to healthy fibroblasts, doxorubicin-loaded HFn was used to treat the cancer cells. The results from confocal microscopy and DNA damage assays proved that loading of doxorubicin in HFn nanoparticles increased the nuclear delivery of the drug, thus enhancing doxorubicin efficacy. Doxorubicin-loaded HFn acts as a "Trojan Horse": HFn was internalized in cancer cells faster and more efficiently compared to free doxorubicin, then promptly translocated into the nucleus following the DNA damage caused by the partial release in the cytoplasm of encapsulated doxorubicin. This self-triggered translocation mechanism allowed the drug to be directly released in the nuclear compartment, where it exerted its toxic action. This approach was reliable and straightforward providing an antiproliferative effect with high reproducibility. The particular self-assembling nature of HFn nanocage makes it a versatile and tunable nanovector for a broad range of molecules suitable both for detection and treatment of cancer cells.

    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. PMID:27022315

    This study sought to assess the impact of health care professional (HCP) communication on breast cancer patients across the acute care process as perceived by patients. Methodological approach was based on eight focus groups conducted with a sample of patients (n = 37) drawn from 15 Spanish Regions; thematic analysis was undertaken using the National Cancer Institute (NCI) framework of HCP communication as the theoretical basis. Relevant results of this study were the identification of four main communication components: (1) reassurance in coping with uncertainty after symptom detection and prompt access until confirmed diagnosis; (2) fostering involvement before delivering treatments, by anticipating information on practical and emotional illness-related issues; (3) guidance on the different therapeutic options, through use of clinical scenarios; and, (4) eliciting the feeling of emotional exhaustion after ending treatments and addressing the management of potential treatment-related effects. These communication-related components highlighted the need for a comprehensive approach in this area of cancer care. PMID:24980292

  12. Outpatient treatment costs and their potential impact on cancer care

    International Nuclear Information System (INIS)

    Cancer creates a tremendous financial burden. Cancer-related costs are categorized into direct, indirect, and psychosocial costs. Although there have been many reports on medical care costs, which are direct, those on other costs are extremely scarce. We estimated travel time and costs required for cancer patients to receive outpatient treatment. We studied 521 cancer patients receiving anti-cancer treatment between February 2009 and December 2012 at the Outpatient Chemotherapy Center of Teikyo University Chiba Medical Center. Address data were extracted from Data Warehouse electronic medical records, and travel distance and time required for outpatient treatment were calculated via MapInfo and ACT Distance Calculator Package. Transportation costs were estimated on the basis of ¥274 (=$3.00) per kilometer. The study design was approved by an ethics review board of Teikyo University (12-851). Average round-trip travel distance, time, and cost for all patients were 26.7 km, 72.5 min, and ¥7,303 ($79.99), respectively. Cancer patients incurred a travel cost of ¥4000–¥9000 ($40.00 to $100.00) for each outpatient treatment. With population aging, seniors living alone and senior households are increasing, and outpatient visits are becoming a common burden

    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. L’intensité des services est caract

    Cancer is the second leading cause of death globally after cardiovascular disease. Long-term cancer survival has improved in the Western world due to early detection and the use of effective combined treatment modalities, as well as the development of effective immunotherapy and drug-targeted therapy. Surgery is still the mainstay for most solid tumors; however, low- and middle-income countries are facing an increasing lack of primary surgical care for easily treatable conditions, including breast, colon, and head and neck cancers. In this paper, a surgical oncology view is presented to elaborate how the Western surgical oncologist can take part in the 'surgical fight' against global disparities in cancer care, and a plea is made to strive for structural solutions, such as a partnership in surgical oncology training. The pros and cons of the use of eHealth and mHealth technologies and education programs for schools and the community are discussed as these create an opportunity to reach a large portion of the population in these countries, at low cost and with high impact.

  17. Socioeconomic status and patterns of care in lung cancer

    International Nuclear Information System (INIS)

    This retrospective study aims to explore any associations between socioeconomic factors and lung cancer management and outcome in the Australian setting. The study population consisted of patients newly diagnosed with lung cancer in 1996 who were living in the Northern Sydney Area Health Service (NSAHS) or South Western Sydney Area Health Service (SWSAHS). These two Area Health Services differ in socioeconomic profiles based on socioeconomic indexes for areas (SEIFA), median income, education level and unemployment rate. Data on patient demographics, tumour characteristics, management details, recurrence and survival were collected, and the patterns of care were analysed. Socioeconomic status indicators of the two Area Health Services were imputed from the Australian Bureau of Statistics data. There were 270 and 256 new cases of lung cancer identified in NSAHS and SWSAHS respectively. Patients in NSAHS were slightly older (median age 73 versus 68 years) and there was less male predominance. The stage distributions and performance status of the two cohorts were similar. There were no significant differences in the utilisation rates of different treatment modalities between the two areas: radiotherapy (54% in NSAHS and 55% in SWSAHS), chemotherapy (34% and 25%), surgery (26% and 21%) and no treatment (22% and 25%). The 5-year overall survival was slightly in favour of NSAHS (10.5% and 7.4%), but did not reach statistical significance. Despite differences in socioeconomic profiles between the two area health services, patients with lung cancer had similar patterns of care and survival

    This paper traces the history of the specialist meanings of 'cure' in paediatric oncology in the UK, how they have changed with increasing organization of the discipline, ever-rising survival rates for all childhood cancers, and with feedback from patients and families. It examines the differing ways in which those involved in researching, treating, and raising funds for work on childhood cancers have understood and used the language of cure, and speculates as to why talking about the 'cure' of survivors of childhood cancers is so problematic. The paper discusses the particular importance of holistic care in the development of paediatric oncology. Psychosocial support is delivered alongside surgery, radiotherapy and chemotherapy. The focus for support is the patient's whole family, building a tenet of palliative care into curative treatment. The concept of the 'truly cured child' is argued to have been crucial in the discipline's decision in the 1970s and 1980s to make the psychosocial needs of patients and their families central in the programme of curing children with cancer.

    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

    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. PMID:27051375

  2. 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

    Information and communication technology (ICT) has the potential to improve the quality of care and efficiency in sexual health clinics, but its introduction requires input not only from health-care professionals and ICT specialists but also from service users and potential future users. In this study, views on ICT in relation to the delivery of sexual health services were assessed using a structured interview in two groups - a community sample of young people and a clinic sample of existing patients. In all, 542 community interviewees and 202 clinic patients participated. About 75% of respondents had access to the Internet and overall 60% reported that the self-collection of a sexual history on an electronic form was acceptable. Black Caribbean individuals had significantly less access to the Internet and a lower acceptance of electronic data collection. For booking an appointment, the majority of patients reported the telephone (community sample 93%, clinic sample 96%) or attending in person (community sample 77%, clinic sample 54%) to be acceptable, with a smaller proportion choosing email (community sample 10%, clinic sample 27%) or the Internet (community sample 7%, clinic sample 11%). Electronic booking was significantly less acceptable to Black Caribbean respondents. Although new technologies offer the opportunity to improve the quality of sexual health services, patient preferences and differences between groups in access to technology also need to be considered when services are reconfigured.

    Objective. The objective of this study was to describe the recent clinical characteristics of labor using 3 systems of Japanese midwife-led primary delivery care, as follows: (1) those intending to give birth at home managed by midwives who do not belong to our hospital, (2) those planning to give birth in our hospital managed by the same midwives, and (3) those planning to give birth managed by midwives who belong to our hospital. Methods. A retrospective cohort study was performed. Results. There were no significant differences in the obstetric or neonatal outcomes among the 3 groups. The rate of transfers during labor with the system involving midwives belonging to our hospital was higher than those with the other 2 systems. In addition, the timing of transfers in the system with the midwives belonging to our hospital was earlier than with the other 2 systems. Among the 3 groups, there were no significant differences in the rate of the main 2 indications for transfers: fetal heart rate abnormality and failure to progress. Conclusion. There were no significant differences in perinatal outcomes among the 3 systems; however, there were some differences in the status of transfers to obstetric shared care. PMID:27034827

    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

    Gemcitabine (GmcH) is an effective anti-cancer agent used in the chemotherapy of lung cancer. However, the clinical applications of GmcH has been impeded primarily due to its low blood residence time, unfavorable pharmacokinetic and pharmacodynamic (PK/PD) profile, and poor penetration in the complex environment of lung cancer cells. Thus, the present study aims to formulate GmcH loaded mannosylated solid lipid nanoparticles (GmcH-SLNs) for improving its drug uptake into the lung cancer cells. GmcH-SLNs were prepared by emulsification and solvent evaporation process, and surface modification was done with mannose using ring opening technique. The cellular toxicity and cell uptake studies were performed in A549 lung adenocarcinoma cell line. The developed nanoformulation appears to be proficient in targeted delivery of GmcH with improved therapeutic effectiveness and enhanced safety. PMID:27459173

    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.

    Small interfering RNA (siRNA) has been demonstrated to be a powerful tool for silencing post-transcriptional gene expression, and thus exhibits great potential in cancer gene therapy. However, siRNA technology has not become an established strategy for cancer treatment, as it is a considerable challenge to deliver siRNA to the targeting sites. In this review, barricades in the systemic delivery of siRNA were systematically introduced, from pharmacokinetics, biodistribution and intracellular behavior. Meanwhile, current and potential strategies for overcoming the barricades were elucidated, including chemical modification of siRNA, nanomaterial-based delivery systems, and targeting and stimuli-responsive smart carriers. In conclusion, the siRNA-based gene silencing drug will gain an important position for treating human diseases if we can solve the gap between ideal and reality. PMID:26511977

    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. PMID:26754042

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

    The objective of this study was to explore health-care professionals', health administrators', and not-for-profit cancer organization representatives' perceptions of lung cancer-related stigma and nihilism and the perceived impacts on funding and patient care. This is a qualitative descriptive study using semi-structured interviews, which was conducted in Ontario, Canada. Seventy-four individuals from medical oncology, radiation oncology, thoracic surgery, respirology, pathology, radiology, primary care, palliative care, nursing, pharmacy, social work, genetics, health administration, and not-for-profit cancer organizations participated in this study. Participants described lung cancer-related stigma and nihilism and its negative impact on patients' psychological health, lung cancer funding, and patient care. The feeling of guilt and shame experienced by lung cancer patients as a result of the stigma associated with the disease was described. In terms of lung cancer funding, stigma was described as a reason lung cancer receives significantly less research funding compared to other cancers. In terms of patient care, lung cancer-related nihilism was credited with negatively impacting physician referral patterns with the belief that lung cancer patients were less likely to receive referrals for medical treatment. Health-care professionals, health administrators, and not-for-profit cancer organization representatives described lung cancer-related stigma and nihilism with far-reaching consequences. Further work is needed to increase education and awareness about lung cancer to reduce the stigma and nihilism associated with the disease. PMID:24882441

    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.

    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. PMID:26994877

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

    Science.gov (United States)

    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.

    Gene therapy is a promising strategy in cancer treatment. However, efficient gene translation still remains challenging. In the previous work, a hydrolytically degradable poly(aminoester) with good biocompatibility was synthesized. Herein, the poly(aminoester) was explored as a vector for gene delivery and cancer therapy. The experiments revealed that the poly(aminoester) condensed plasmid DNA into nanosized particles via electrostatic interaction. The pEGFP-N1 and pGL-3 were first used as two reporter genes to study intracellular transfection. The poly(aminoester) showed higher GFP expression (33%) than PEI 25 kDa (21%). Intracellular trafficking of Cy3-labelled pGL-3 also indicated that the poly(aminoester) showed superior DNA delivery ability to nucleus compared to PEI 25 kDa. Furthermore, the therapeutic gene (p53) was translated into the breast cancer cell line (MCF-7), and then induced cell apoptosis. These results suggested that the degradable poly(aminoester) is a promising and efficient gene delivery vector for gene therapeutic applications. PMID:27455620

    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.

    Full Text Available Objective: Advanced oral cancers are a challenge for treatment, as they require complex procedures for excision and reconstruction. Despite being occurring at a visible site and can be detected easily, many patients present in advanced stages with large tumors. Timely intervention is important in improving survival and quality of life in these patients. The aim of the present study was to find out the causes of delay in seeking specialist care in advanced oral cancer patients. Materials and Methods: A prospective questionnaire based study was done on 201 consecutive advanced oral squamous cancer patients who underwent surgery at our hospital. All patients had either cancer of gingivobuccal complex (GBC or tongue and had tumors of size more than 4 cm (T3/T4 and were treatment naοve at presentation. RESULTS: Even though most patients observed abnormal lesions in their mouth, majority delayed the decision to visit a physician early. A significant percentage of patients (50% also reported a delayed diagnosis by the primary care physician before being referred to a tertiary care center for definitive treatment. The average total duration from symptoms to treatment was 7 months. Conclusion: The main reasons of this delay in receiving treatment were due to patients themselves (primary delay or due to time taken by the primary physician to diagnose the condition (secondary delay. Oral self-examination can be helpful in detecting oral cancers early.

    Background Due to the increasing prevalence of obesity within the general population it is presumed that the prevalence of overweight and obese adults accessing dental services will also increase. For this reason dentists need to be aware of implications of managing such patients.Methods A scoping review was carried out. Both Medline via OVID and Scopus databases were searched along with grey literature databases and the websites of key organizations. Inclusion and exclusion criteria were established. The data were collected on a purpose-made data collection form and analysed descriptively.Results The review identified 28 relevant published articles and two relevant items of grey literature. Following review of this literature three themes relating to adult obesity in the delivery and acceptance of dental care emerged; clinical, service delivery and patient implications. The majority of the papers focused on the clinical implications.Conclusion On the topic of adult obesity and dental care, the majority of published and grey literature focuses on the clinical implications. Further research is needed on both the patients' perspectives of being overweight or obese and the delivery and acceptance of dental care and the service delivery implications. PMID:27608579

    2013-01-01

    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.

    Cancer is the major cause of fatality and the number of new cases is increasing incessantly. Conventional therapies and existing anticancer agents cause serious side effects and expand the patient's lifespan by a few years. There is the need to exploit alternative anticancer agents and novel drug delivery system to deliver these agents to the tumor site for the prevention of cancer. Recently, biologically active compounds isolated from plants used for the management of cancer have been the heart of interest. Capsaicin is a major pungent agent present in the chili peppers that is heavily consumed in the world. Capsaicin has demonstrated effectiveness as an anticancer agent, but a restraining factor is its pungency, extremely low aqueous solubility, and poor oral bioavailability which impede its use as an anticancer agent. Many technologies have been developed and applied to conquer this drawback. We bring to light the benefits of this phytoconstituent for treating different types of cancer. We also discussed some of the delivery approaches that have already made an impact by either delivering a drug to target tissue or increasing its bioavailability by many folds. PMID:26036845

    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. PMID:21545358

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

    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.

    A significant proportion of cancer patients and survivors are age 65 and over. Older adults with cancer often have more complex medical and social needs than their younger counterparts. Geriatric medicine providers (GMPs) such as geriatricians, geriatric-trained advanced practice providers, and geriatric certified registered nurses have expertise in caring for older adults, managing complex medical situations, and optimizing function and independence for this population. GMPs are not routinely incorporated into cancer care for older adults; however, their particular skill set may add benefit at many points along the cancer care continuum. In this article, we review the role of geriatric assessment in the care of older cancer patients, highlight specific case scenarios in which GMPs may offer additional understanding and insight in the care of older adults with cancer, and discuss specific mechanisms for incorporating GMPs into oncology care.

    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.

    Full text: Intensity Modulated Radiation Therapy (IMRT) has the potential to conform dose to complex target structures as well as sparing normal tissue. The complexity of the technique requires additional verification steps to ensure that the treatments are planned, transferred and delivered correctly. IMRT was introduced at the Illawarra Cancer Care Centre (ICCC) in 2002. Since that time over 70 head-and-neck cases have been treated. An overview of the current IMRT QA program at the ICCC and a summary of QA results for the last 5 years will be presented.

  10. Supportive care for head and neck cancer patients receiving radiotherapy

    International Nuclear Information System (INIS)

    Recently (chemo-)radiotherapy has been widely used in head and neck cancer with definite evidence. As long survivor has increased, social problems associated with late toxicity have become more. Late toxicities induced by radiotherapy for head and neck lesion are often severe. Xerostomia is one of the severe late toxicities conventionally and dysphagia after chemoradiotherapy is a new topic. Some industrial development (ex. Intensity Modulated Radiotherapy: IMRT) play a great role in toxicity management. Multidisciplinary approach (cooperation between not only physicians but also nurses and dentists) is necessary to control toxicities. The research of supportive care will be needed same as definitive treatment in the future. (author)

  11. The role of university hospitals as centers of excellence for shared health-care-delivery of in- and outpatients

    International Nuclear Information System (INIS)

    Problem. Health care delivery in Germany has to face severe challenges that will lead to a closer integration of services for in- and out-patients. University hospitals play an important role due to their activities in research, education and health care delivery. They are requested to promote and evaluate new means and ways for health care delivery. Methods. The Institute of Clinical Radiology at the University Hospital of the Ludwig-Maximilians-University started teleradiological services for hospitals and general practices in January 1999 in the framework of the ''Imaging services - teleradiological center of excellence''. Legal, technical and organizational prerequisites were analyzed. Results. Networks between university hospitals and general practices are not likely to solve all future problems. They will, however, increase the availability of the knowledge of experts even in rural areas and contribute to a quality ensured health care at the patients home. Future developments may lead to international co-operations and such services may be available to patients abroad. Conclusion. Legal, technical and organizational obstacles have to be overcome to create a framework for high quality telemedical applications. University hospitals will play an important role in promoting and evaluating teleradiological services. (orig.)

    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.

    Palliative care is patient and family-centred care that optimises quality of life by anticipating, preventing, and treating suffering. Open Society Foundation public health program (2011) notes that people facing life-threatening illnesses are deeply vulnerable: often in severe physical pain, worried about death, incapacitation, or the fate of their loved ones. Legal issues can increase stress for patients and families and make coping harder, impacting on the quality of care. In the absence of a clear legal provision expressly recognising palliative care in Kenya, providers may face numerous legal and ethical dilemmas that affect the availability, accessibility, and delivery of palliative care services and commodities. In order to ensure positive outcomes from patients, their families, and providers, palliative care services should be prioritised by all and includes advocating for the integration of legal support into those services. Palliative care service providers should be able to identify the various needs of patients and their families including specific issues requiring legal advice and interventions. Access to legal services remains a big challenge in Kenya, with limited availability of specialised legal services for health-related legal issues. An increased awareness of the benefits of legal services in palliative care will drive demand for easily accessible and more affordable direct legal services to address legal issues for a more holistic approach to quality palliative care.

  17. Adenoviral delivery of the EMX2 gene suppresses growth in human gastric cancer.

    Directory of Open Access Journals (Sweden)

    Jie Li

    Full Text Available BACKGROUND: EMX2 is a human orthologue of the Drosophila empty spiracles homeobox gene that has been implicated in embryogenesis. Recent studies suggest possible involvement of EMX2 in human cancers; however, the role of EMX2 in carcinogenesis needs further exploration. RESULTS: In this study, we reported that down-regulation of EMX2 expression was significantly correlated with EMX2 promoter hypermethylation in gastric cancer. Restoring EMX2 expression using an adenovirus delivery system in gastric cancer cell lines lacking endogenous EMX2 expression led to inhibition of cell proliferation and Wnt signaling pathway both in vitro and in a gastric cancer xenograft model in vivo. In addition, we observed that animals treated with the adenoviral EMX2 expression vector had significantly better survival than those treated with empty adenoviral vector. CONCLUSION: Our study suggests that EMX2 is a putative tumor suppressor in human gastric cancer. The adenoviral-EMX2 may have potential as a novel gene therapy for the treatment of patients with gastric cancer.

    2013-01-01

    In this article, we report on a small qualitative scale study with immigrant Russian-speaking Australian women, carers of dependent family members. Drawing on in-depth interviews, we explore women's health-related behaviours, in particular their participation in breast and cervical cancer screening. Differences in preventive health care policies in country of origin and Australia explain their poor participation in cancer screening. Our participants had grown up in the former Soviet Union, where health checks were compulsory but where advice about frequency and timing was the responsibility of doctors. Following migration, women continued to believe that the responsibility for checks was their doctor's, and they maintained that, compared with their experience of preventive medicine in the former Soviet Union, Australian practice was poor. Women argued that if reproductive health screening were important in cancer prevention, then health care providers would take a lead role to ensure that all women participated. Data suggest how women's participation in screening may be improved. PMID:22951044

    2012-12-01

    In this paper, a targeted drug delivery system has been developed based on hyaluronic acid (HA) modified mesoporous silica nanoparticles (MSNs). HA-MSNs possess a specific affinity to CD44 over-expressed on the surface of a specific cancer cell line, HCT-116 (human colon cancer cells). The cellular uptake performance of fluorescently labelled MSNs with and without HA modification has been evaluated by confocal microscopy and fluorescence-activated cell sorter (FACS) analysis. Compared to bare MSNs, HA-MSNs exhibit a higher cellular uptake via HA receptor mediated endocytosis. An anticancer drug, doxorubicin hydrochloride (Dox), has been loaded into MSNs and HA-MSNs as drug delivery vehicles. Dox loaded HA-MSNs show greater cytotoxicity to HCT-116 cells than free Dox and Dox-MSNs due to the enhanced cell internalization behavior of HA-MSNs. It is expected that HA-MSNs have a great potential in targeted delivery of anticancer drugs to CD44 over-expressing tumors.

    Purpose Cancer treatments are frequently associated with adverse effects, but there may be a cultural reluctance by care providers to be forthcoming with patients regarding these risks for fear of promoting nonadherence. Conversely, research in a number of countries indicates high levels of patient desire for this information. We sought to explore cancer patient experiences, satisfaction, and preferences for medication risk communication in a Middle East care setting. Methods We developed and administered a ten-item questionnaire (Arabic and English) to a convenience sample of consenting adult patients receiving treatment at the National Center for Cancer Care and Research in Qatar. Results One hundred and forty-three patients were interviewed. Most (88%) stated that the level of side effect information they received was sufficient, with physicians (86%) followed by pharmacists (39%) as the preferred sources. The majority (97%) agreed that knowing about possible side effects would help them recognize and manage the reaction, and 92% agreed that it would help them understand how to minimize or prevent the risks. Eighteen percent indicated that this information would make them not want to take treatment. Two-thirds (65%) had previously experienced intolerance to their cancer treatment regimen. Conclusion Most patients surveyed expressed preference for the details of possible side effects they may encounter in their treatment. However, one in five considered such information a factor for nonadherence, indicating the need for patient-specific approaches when communicating medication risks. PMID:27175061

    Full Text Available Eve Denton,1 Matthew Conron2 1Allergy, Immunology and Respiratory Department, Alfred Hospital, 2Department of Respiratory and Sleep Medicine, St Vincent's Hospital, Melbourne, VIC, Australia Abstract: Lung cancer is a major worldwide health burden, with high disease-related morbidity and mortality. Unlike other major cancers, there has been little improvement in lung cancer outcomes over the past few decades, and survival remains disturbingly low. Multidisciplinary care is the cornerstone of lung cancer treatment in the developed world, despite a relative lack of evidence that this model of care improves outcomes. In this article, the available literature concerning the impact of multidisciplinary care on key measures of lung cancer outcomes is reviewed. This includes the limited observational data supporting improved survival with multidisciplinary care. The impact of multidisciplinary care on other benchmark measures of quality lung cancer treatment is also examined, including staging accuracy, access to diagnostic investigations, improvements in clinical decision making, better utilization of radiotherapy and palliative care services, and improved quality of life for patients. Health service research suggests that multidisciplinary care improves care coordination, leading to a better patient experience, and reduces variation in care, a problem in lung cancer management that has been identified worldwide. Furthermore, evidence suggests that the multidisciplinary model of care overcomes barriers to treatment, promotes standardized treatment through adherence to guidelines, and allows audit of clinical services and for these reasons is more likely to provide quality care for lung cancer patients. While there is strengthening evidence suggesting that the multidisciplinary model of care contributes to improvements in lung cancer outcomes, more quality studies are needed.

    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. PMID:26578263

    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.

    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.

    Full Text Available We present an in-silico-to-in-vitro approach to develop well-defined, self-assembled, rigid-cored polymeric (Polybee nano-architecture for controlled delivery of a key component of bee venom, melittin. A competitive formulation with lipid-encapsulated (Lipobee rigid cored micelle is also synthesized. In a series of sequential experiments, we show how nanoscale chemistry influences the delivery of venom toxins for cancer regression and help evade systemic disintegrity and cellular noxiousness. A relatively weaker association of melittin in the case of lipid-based nanoparticles is compared to the polymeric particles revealed by energy minimization and docking studies, which are supported by biophysical studies. For the first time, the authors' experiment results indicate that melittin can play a significant role in DNA association-dissociation processes, which may be a plausible route for their anticancer activity.

  11. Magnetic iron oxide nanoparticles as drug delivery system in breast cancer

    International Nuclear Information System (INIS)

    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.

    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.

    Aging patients with advanced or terminal illnesses or at the end of their lives become highly vulnerable when their cultural needs-in terms of ethnic habits, religious beliefs, and language-are unmet. Cultural diversity should be taken into account during palliative care delivery (i.e., noncurative, supportive care during advanced illness or at the end of life). Providers and systems deliver disparate palliative care to diverse patients. I present 2 strategies to improve how culturally diverse populations are served during advanced illness: (1) health service provider assessment of local populations to understand service populations' cultural needs and guide services and policy; and (2) interprofessional education to improve multicultural understanding among the health care workforce.

    In this study, a highly effective transmembrane delivery vehicle based on PEGylated oxidized mesoporous carbon nanosphere (oMCN@PEG) was successfully fabricated in a facile strategy. oMCN@PEG exhibited a narrow size distribution of 90 nm, excellent hydrophilicity, good biocompatibility, and a very high loading efficiency for doxorubicin (DOX). The drug system (oMCN@DOX@PEG) exhibited excellent stability under neutral pH conditions, but with dramatic releases of DOX at reduced pH conditions. Pharmacokinetics study revealed that oMCN@DOX@PEG could prolong the circulation of DOX in the blood stream. The endocytosis, cytotoxicity, and anticancer effect in vitro and in vivo of the drug-loaded nanoparticles were also evaluated. Our results showed that the nanoparticles efficiently penetrated the membrane of tumor cells, subsequently released drugs, and efficiently inhibited the growth of cancer cells both in vitro and in vivo. Especially, oMCN@DOX@PEG also exhibited significant antimetastasis effect in advanced stage of malignant cancer, improving the survival time of tumor-bearing mice. The results suggested that oMCN@PEG might be a promising anticancer drug delivery vehicle for cancer therapy. PMID:27175077

    Drug delivery systems (DDSs) with biocompatibility and precise drug delivery are eagerly needed to overcome the paradox in chemotherapy that high drug doses are required to compensate for the poor biodistribution of drugs with frequent dose-related side effects. In this work, we reported a metal-organic framework (MOF) based tumor targeting DDS developed by a one-pot, and organic solvent-free ``green'' post-synthetic surface modification procedure, starting from the nanoscale MOF MIL-101. Owing to the multifunctional surface coating, premature drug release from this DDS was prevented. Due to the pH responsive benzoic imine bond and the redox responsive disulfide bond at the modified surface, this DDS exhibited tumor acid environment enhanced cellular uptake and intracellular reducing environment triggered drug release. In vitro and in vivo results showed that DOX loaded into this DDS exhibited effective cancer cell inhibition with much reduced side effects.Drug delivery systems (DDSs) with biocompatibility and precise drug delivery are eagerly needed to overcome the paradox in chemotherapy that high drug doses are required to compensate for the poor biodistribution of drugs with frequent dose-related side effects.

  17. Polymeric nanoparticles for the intracellular delivery of paclitaxel in lung and breast cancer

    Science.gov (United States)

    Zubris, Kimberly Ann Veronica

    Nanoparticles are useful for addressing many of the difficulties encountered when administering therapeutic compounds. Nanoparticles are able to increase the solubility of hydrophobic drugs, improve pharmacokinetics through sustained release, alter biodistribution, protect sensitive drugs from low pH environments or enzymatic alteration, and, in some cases, provide targeting of the drug to the desired tissues. The use of functional nanocarriers can also provide controlled intracellular delivery of a drug. To this end, we have developed functional pH-responsive expansile nanoparticles for the intracellular delivery of paclitaxel. The pH-responsiveness of these nanoparticles occurs due to a hydrophobic to hydrophilic transition of the polymer occurring under mildly acidic conditions. These polymeric nanoparticles were systematically evaluated for the delivery of paclitaxel in vitro and in vivo to improve local therapy for lung and breast cancers. Nanoparticles were synthesized using a miniemulsion polymerization process and were subsequently characterized and found to swell when exposed to acidic environments. Paclitaxel was successfully encapsulated within the nanoparticles, and the particles exhibited drug release at pH 5 but not at pH 7.4. In addition, the uptake of nanoparticles was observed using flow cytometry, and the anticancer efficacy of the paclitaxel-loaded nanoparticles was measured using cancer cell lines in vitro. The potency of the paclitaxel-loaded nanoparticles was close to that of free drug, demonstrating that the drug was effectively delivered by the particles and that the particles could act as an intracellular drug depot. Following in vitro characterization, murine in vivo studies demonstrated the ability of the paclitaxel-loaded responsive nanoparticles to delay recurrence of lung cancer and to prevent establishment of breast cancer in the mammary fat pads with higher efficacy than paclitaxel alone. In addition, the ability of nanoparticles to

    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.

    Chemoprevention of human cancer by dietary products is a practical approach of cancer control, especially when chemoprevention is involved during the early stages of the carcinogenesis process. Research over the last few decades has clearly demonstrated the efficacy of dietary products for chemoprevention in cell culture and preclinical animal model systems. However, these in vitro and in vivo effects have not been able to be translated to bedside for clinical use. Among many reasons, inefficient systemic delivery and bioavailability of promising chemopreventive agents are considered to significantly contribute to such a disconnection. Since its advent in the field of cancer, nanotechnology has provided researchers with expertise to explore new avenues for diagnosis, prevention, and therapy of the disease. In a similar trait, we introduced a novel concept in which nanotechnology was utilized for enhancing the outcome of chemoprevention (Cancer Res. 2009; 69:1712-1716). This idea, which we termed as 'nanochemoprevention', was exploited by several laboratories and has now become an advancing field in chemoprevention research. This review summarizes some of these applications of nanotechnology in medicine, particularly focused on controlled and sustained release of bioactive compounds with emphasis on current and future utilization of nanochemoprevention for prevention and therapy of cancer.

    Three half-sandwich iridium and ruthenium organometallic complexes with high cytotoxicity are synthesized, and their anticancer mechanisms are elucidated. The organometallic complexes can interact with DNA through coordination or intercalation, thereby inducing apoptosis and inhibiting proliferation of resistant cancer cells. The organometallic complexes are then incorporated into polymeric micelles through the polymer-metal coordination between poly(ethylene glycol)-b-poly(glutamic acid) [PEG-b-P(Glu)] and organometallic complexes to further enhance their anticancer effects as a result of the enhanced permeability and retention effect. The micelles with particle sizes of ≈60 nm are more efficiently internalized by cancer cells than the corresponding complexes, and selectively dissociate and release organometallic anticancer agents within late endosomes and lysosomes, thereby enhancing drug delivery to the nuclei of cancer cells and facilitating their interactions with DNA. Thus, the micelles display higher antitumor activity than the organometallic complexes alone with a lack of the systemic toxicity in a mouse xenograft model of cisplatin-resistant human ovarian cancer. These results suggest that the polymeric micelles carrying anticancer organometallic complexes provide a promising platform for the treatment of resistant ovarian cancer and other hard-to-treat solid tumors.

    We report the development and characterization of a novel nanometric system for specific delivery of therapeutic siRNA for cancer treatment. This vector is based on a binary mixture of the cationic surfactant dioctadecyldimethylammonium chloride (DODAC) and the helper lipid monoolein (MO). These liposomes were previously validated by our research group as promising non-viral vectors for nucleic acid delivery. In this work, the DODAC:MO vesicles were for the first time functionalized with polyethylene glycol and PEG-folate conjugates to achieve both maximal stability in biological fluids and increase selectivity toward folate receptor α expressing cells. The produced DODAC:MO:PEG liposomes were highly effective in RNA complexation (close to 100%), and the resulting lipoplexes also demonstrated high stability in conditions simulating their administration by intravenous injection (physiological pH, high NaCl, heparin and fetal bovine serum concentrations). In addition, cell uptake of the PEG-folate-coated lipoplexes was significantly greater in folate receptor α positive breast cancer cells (39% for 25 µg/mL of lipid and 31% for 40 µg/mL) when compared with folate receptor α negative cells (31% for 25 µg/mL of lipid and 23% for 40 µg/mL) and to systems without PEG-folate (≈13% to 16% for all tested conditions), supporting their selectivity towards the receptor. Overall, the results support these systems as appealing vectors for selective delivery of siRNA to cancer cells by folate receptor α-mediated internalization, aiming at future therapeutic applications of interest.

    A folate-decorated, disulfide-based cationic dextran conjugate having dextran as the main chain and disulfide-linked 1,4-bis(3-aminopropyl)piperazine (BAP) residues as the grafts was designed and successfully prepared as a multifunctional gene delivery vector for targeted gene delivery to ovarian cancer SKOV-3 cells in vitro and in vivo. Initially, a new bioreducible cationic polyamide (denoted as pSSBAP) was prepared by polycondensation reaction of bis(p-nitrophenyl)-3,3'-dithiodipropanoate, a disulfide-containing monomer, and BAP. It was found that the pSSBAP was highly efficient for in vitro gene delivery against MCF-7 and SKOV-3 cell lines. Subsequently, two cationic dextran conjugates with different amounts of BAP residues (denoted as Dex-SSBAP6 and Dex-SSBAP30, respectively) were synthesized by coupling BAP to disulfide-linked carboxylated dextran or coupling pSSBAP-oligomer to p-nitrophenyl carbonated dextran. Both two conjugates were able to bind DNA to form nanosized polyplexes with an improved colloidal stability in physiological conditions. The polyplexes, however, were rapidly dissociated to liberate DNA in a reducing environment. In vitro transfection experiments revealed that the polyplexes of Dex-SSBAP30 efficiently transfected SKOV-3 cells, yielding transfection efficiency that is comparable to that of linear polyethylenimine or lipofectamine 2000. AlamarBlue assay showed that the conjugates had low cytotoxicity in vitro at a high concentration of 100 mg/L. Further, Dex-SSBAP30 has primary amine side groups and thus allows for folate (FA) conjugation, yielding FA-coupled Dex-SSBAP30 (Dex-SSBAP30-FA). It was found that Dex-SSBAP30-FA was efficient for targeted gene delivery to SKOV-3 tumor xenografted in a nude mouse model by intravenous injection, inducing a higher level of gene expression in the tumor as compared to Dex-SSBAP30 lacking FA and comparable gene expression to linear polyethylenimine as one of the most efficient polymeric vectors for

    Full Text Available Abstract Background Recent years have seen an unprecedented increase in funds for procurement of health commodities in developing countries. A major challenge now is the efficient delivery of commodities and services to improve population health. With this in mind, we documented staffing levels and productivity in peripheral health facilities in southern Tanzania. Method A health facility survey was conducted to collect data on staff employed, their main tasks, availability on the day of the survey, reasons for absenteeism, and experience of supervisory visits from District Health Teams. In-depth interview with health workers was done to explore their perception of work load. A time and motion study of nurses in the Reproductive and Child Health (RCH clinics documented their time use by task. Results We found that only 14% (122/854 of the recommended number of nurses and 20% (90/441 of the clinical staff had been employed at the facilities. Furthermore, 44% of clinical staff was not available on the day of the survey. Various reasons were given for this. Amongst the clinical staff, 38% were absent because of attendance to seminar sessions, 8% because of long-training, 25% were on official travel and 20% were on leave. RCH clinic nurses were present for 7 hours a day, but only worked productively for 57% of time present at facility. Almost two-third of facilities had received less than 3 visits from district health teams during the 6 months preceding the survey. Conclusion This study documented inadequate staffing of health facilities, a high degree of absenteeism, low productivity of the staff who were present and inadequate supervision in peripheral Tanzanian health facilities. The implications of these findings are discussed in the context of decentralized health care in Tanzania.

    Kohka Public Hospital(KPH)was rebuilt at a new place in April 2013. The Palliative Care Unit(PCU)was newly constructed during renovation. We examined the will and outcome of cancer patients, especially on expiration. A 123 patients died in 2014: 27 died at the PCU, and the remaining 7 at home. Of 27 patients, 20 were willing to die at the PCU, and one patient visited the hospital after judgment by the Visiting Nurse Center. Other 6 patients were admitted finally after their families experienced fatigue. Six of seven patients who died at home, showed a strong will to stay at home. We think that patients' will drives the clinical course, especially in their end-stage. In this context, the majority of the patients decided their terminal place based on their will. On the contrary, there were several cases whose requests were not fulfilled. To overcome the problem, we should discuss cancer patients' will to make a choice regarding death at the end-stage of their lives and the place of expiration in advance. We including the staff of social care and regional medical resources, should co-operate and share information on these patients to solve the problems. PMID:26809413

    This paper presents preliminary results on the use of transferrin protein nanospheres (TfpNS) for targeting cancer cells in vitro. Protein nanospheres represent an easily prepared and modifiable nanoplatform for receptor-specific targeting, molecular imaging and gene delivery. Rhodamine B isothiocyanate conjugated TfpNS (RBITC-TfpNS) show significantly enhanced uptake in vitro in SK-MEL-28 human malignant melanoma cells known to overexpress transferrin receptors compared to controls. RBITCTfpNS labeling of the cancer cells is due to transferrin receptor-mediated uptake, as demonstrated by competitive inhibition with native transferrin. Initial fluorescence microscopy studies indicate GFP plasmid can be transfected into melanoma cells via GFP plasmid encapsulated by TfpNS.

    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.

    Full Text Available Abstract Background Efforts to reduce neonatal mortality are essential if the Millennium Development Goal (MDG 4 is to be met. The impact of spatial dimensions of neonatal survival has not been thoroughly investigated even though access to good quality delivery care is considered to be one of the main priorities when trying to reduce neonatal mortality. This study examined the association between distance from the mother's home to the closest health facility and neonatal mortality, and investigated the influence of distance on patterns of perinatal health care utilisation. Methods A surveillance system of live births and neonatal deaths was set up in eight districts of Quang Ninh province, Vietnam, from July 2008 to December 2009. Case referent design including all neonatal deaths and randomly selected newborn referents from the same population. Interviews were performed with mothers of all subjects and GIS coordinates for mothers' homes and all health facilities in the study area were obtained. Straight-line distances were calculated using ArcGIS software. Results A total of 197 neonatal deaths and 11 708 births were registered and 686 referents selected. Health care utilisation prior to and at delivery varied with distance to the health facility. Mothers living farthest away (4th and 5th quintile, ≥1257 meters from a health facility had an increased risk of neonatal mortality (OR 1.96, 95% CI 1.40 - 2.75, adjusted for maternal age at delivery and marital status. When stratified for socio-economic factors there was an increased risk for neonatal mortality for mothers with low education and from poor households who lived farther away from a health facility. Mothers who delivered at home had more than twice as long to a health facility compared to mothers who delivered at a health care facility. There was no difference in age at death when comparing neonates born at home or health facility deliveries (p = 0.56. Conclusion Distance to the

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

    Although many patients wish to remain in their familiar home environment while undergoing cancer treatment, many obstacles prevent a patient from receiving cancer care at home. With early-stage cancer, the patients may better accept the diagnosis and have a greater will to fight the illness. However as time proceeds, progression or recurrence of cancer may occur, and eventually, proactive treatments will not be available. This progression results in great physical and mental strain on the patients and their family. At all stages of such progression, opportunities exist for a care provider to assist with overcoming potential obstacles by openly communicating with the patients, talking through the patients' experiences, and understanding their feelings. However, on diagnosis, cancer patients must often face the reality that they have very little time left to live. When transiting medical care from their long-trusted hospital to a home care base, a new physician must be selected and other decisions related to their care must be quickly made. Transferring responsibility to a good home care provider can greatly influence a patient's emotional state. This paper reports one such case in which the patients died in their homes with the best comfort and possible outcome. PMID:26809394

    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.

    Nanocarriers are heavily researched as drug delivery vehicles capable of sequestering antineoplastic agents and then releasing their contents at the desired location. The feasibility of using such carriers stems from their ability to produce a multimodel delivery system whereby passive, ligand and triggered targeting can be applied in the fight against cancer. Passive targeting capitalizes on the leaky nature of tumor tissue which allows for the extravasation of particles with a size smaller than 0.5 µm into the tumors. Ligand targeting utilizes the concept of receptor-mediated endocytosis and involves the conjugation of ligands onto the surface of nanoparticles, while triggered targeting involves the use of external and internal stimuli to release the carriers contents upon reaching the diseased location. In this review, micelles and liposomes have been considered due to the promising results they have shown in vivo and in vitro and their potential for advancements into clinical trials. Thus, this review focuses on the most recent advancements in the field of micellar and liposomal drug delivery and considers the synergistic effect of passive- and ligand-targeting strategies, and the use of ultrasound in triggering drug release at the tumor site.

    Drug delivery systems are required for drug targeting to avoid adverse effects associated with chemotherapy treatment regimes. Our approach is focused on the study and development of plant virus-based materials as drug delivery systems; specifically, this work focuses on the tobacco mosaic virus (TMV). Native TMV forms a hollow, high aspect-ratio nanotube measuring 300×18nm with a 4nm-wide central channel. Heat-transformation can be applied to TMV yielding spherical nanoparticles (SNPs) measuring ~50nm in size. While bioconjugate chemistries have been established to modify the TMV rod, such methods have not yet been described for the SNP platform. In this work, we probed the reactivity of SNPs toward bioconjugate reactions targeting lysine, glutamine/aspartic acid, and cysteine residues. We demonstrate functionalization of SNPs using these chemistries yielding efficient payload conjugation. In addition to covalent labeling techniques, we developed encapsulation techniques, where the cargo is loaded into the SNP during heat-transition from rod-to-sphere. Finally, we developed TMV and SNP formulations loaded with the chemotherapeutic doxorubicin, and we demonstrate the application of TMV rods and spheres for chemotherapy delivery targeting breast cancer.

    The impetus for this qualitative study was the premise expressed by lay people that nursing terminally ill cancer patients must be depressing and difficult to cope with. Its focus was nurses' stress and coping strategies, both secular and religious. Data was collected using a narrative life-story approach, and then Lazaruz and Folkman's coping theory and Pargament's theory on the psychology of religion were used during the analysis of the data. Several factors were identified, related to the individual and group levels, that influence a nurse's identity and professional development. A person's life orientation was suggested as a first concept for developing a professional paradigm that includes caritas as a main orienting factor. Directed by the nurse's secular and religious orientation, competence develops, making it possible to understand, analyze, manage, and appreciate the significance of the professional work of caring.

    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. PMID:26874284

    This review is an attempt to assess the different classes of phytochemicals and some of their members which have been encapsulated into nanocarrier systems for their chemotherapeutic or chemopreventive properties. Given the broad spectrum of nanomedicines currently in clinical trial and clinical use from polymer-protein conjugates, through nanocrystals, nanogels, dendrimers to ethosomes, the focus of this review will be on block copolymer nanomicelles, nanoparticles, polymer-drug conjugates, liposomes and solid lipid nanocarriers (SLNs). The twenty phytochemicals investigated for encapsulation and targeted delivery were selected from a variety of classes intended to encompass the largest possible chemical compositions, namely flavonoids, aromatic acids, xanthones, terpenes, quinones, lignans and alkaloids. To the best of our knowledge, reviews on the nanoencapsulation of these phytochemicals and their delivery are not available. In this review, the issues associated with the limited use of each phytochemical in cancer therapy in humans are reviewed and the advantages of entrapment into nanocarriers are assessed in terms of drug loading efficiency, size of nanocarriers, drug release profiles and in vitro and/or in vivo testing specific to cancer research, e.g., cytotoxicity assay, cell inhibition/viability, scavenging of reactive oxygen species and biodistribution studies (elimination half-life and mean residence time).

    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.

    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.

    Elysia Larson

    Full Text Available In order to develop patient-centered care we need to know what patients want and how changing socio-demographic factors shape their preferences.We fielded a structured questionnaire that included a discrete choice experiment to investigate women's preferences for place of delivery care in four rural districts of Pwani Region, Tanzania. The discrete choice experiment consisted of six attributes: kind treatment by the health worker, health worker medical knowledge, modern equipment and medicines, facility privacy, facility cleanliness, and cost of visit. Each woman received eight choice questions. The influence of potential supply- and demand- side factors on patient preferences was evaluated using mixed logit models.3,003 women participated in the discrete choice experiment (93% response rate completing 23,947 choice tasks. The greatest predictor of health facility preference was kind treatment by doctor (β = 1.13, p<0.001, followed by having a doctor with excellent medical knowledge (β = 0.89 p<0.001 and modern medical equipment and drugs (β = 0.66 p<0.001. Preferences for all attributes except kindness and cost were changed with changes to education, primiparity, media exposure and distance to nearest hospital.Care quality, both technical and interpersonal, was more important than clinic inputs such as equipment and cleanliness. These results suggest that while basic clinic infrastructure is necessary, it is not sufficient for provision of high quality, patient-centered care. There is an urgent need to build an adequate, competent, and kind health workforce to raise facility delivery and promote patient-centered care.

  15. Considerations for Implementation of Cancer Molecular Diagnostics Into Clinical Care.

    Hayes, Daniel F

    2016-01-01

    Physicians have provided personalized care with as much precision as possible for several centuries. However, increasingly sophisticated understanding of the human genome and of cancer biology has permitted identification of genetic and phenotypic distinctions that might permit development of new tumor biomarker tests for risk categorization, screening, differential diagnosis, prognosis, prediction, and monitoring. Both commercial and academic laboratories are offering tests for single analytes, panels of tests of single analytes, multiparameter assays coalesced into a signature, and total genomic, transcriptomic, or proteomic analyses. However, the absence of a consistent regulatory environment has led to marketing of assays without proven analytic validity or clinical utility. U.S. Food and Drug Administration (FDA) approval or clearance does not necessarily imply that use of the test will improve patient outcomes, and FDA discretion to permit laboratory-developed tests results in unknown benefit, or harm, of others. In this regard, a "bad tumor marker is as bad as a bad drug." Caveat emptor is not a satisfactory approach to delivering high-quality care. Rather, adoption of tumor biomarker tests should be based on high levels of evidence generated in scientifically rigorous studies that demonstrate both analytical validity and clinical utility. Doing so will ensure that clinicians and patients are confident that a tumor biomarker test is likely to improve their outcomes. PMID:27249708

    Full Text Available The number of long-term survivors is increasing in the western countries due to remarkable improvements in the treatment of childhood cancer. The long-term complications of childhood cancer survivors in these countries were brought to light by the childhood cancer survivor studies. In Korea, the 5-year survival rate of childhood cancer patients is approaching 70%; therefore, it is extremely important to undertake similar long-term follow-up studies and comprehensive long-term care for our population. On the basis of the experiences of childhood cancer survivorship care of the western countries and the current Korean status of childhood cancer survivors, long-term follow-up study and long-term care systems need to be established in Korea in the near future. This system might contribute to the improvement of the quality of life of childhood cancer survivors through effective intervention strategies.

    Full Text Available This study aims to understand the experience of adolescents with cancer, family and the health team regarding death in the healthcare context, in the light of Edgar Morin's proposed theoretical framework of complexity. Participants were 12 adolescents, 14 relatives and 25 health professionals. The interview was used for data collection. The discussion of data was guided by the dialogic life-death in the context of care to adolescents with cancer. It was observed that the singularity in the way the adolescent experiences time and faces death and the possibility that the family will lose a loved one may not be in accordance with the care the health team offers, considering structural, organizational and affective aspects. It is not enough for the team just to rationally make choices on the use of diagnostic-therapeutic devices, in line with predefined moments in the disease. Instead, a contextualized and sensitive understanding of each situation is needed.El estudio objetivó comprender la experiencia de los adolescentes con cáncer, de los familiares y del equipo de salud relacionada a la muerte en el contexto del cuidado de salud, bajo el marco teórico de la complejidad propuesto por Edgar Morin.

Third-year students enrolled in the course were surveyed regarding elements of redesign and homework completion. Additionally, their performance and incoming grade point average were evaluated. Assessment. A survey was completed by 286 of 305 students. Nineteen percent of respondents preferred traditional content delivery, whereas 30% preferred flipped TBL, 48% preferred a mixed format, and 3% had no preference. The grades achieved in the course were: A (49%), B (48%), C (3%) and D (0%). The majority completed “all” or “most” of the homework, appreciated attributes of course redesign, felt home preparation and in-class activities engaged them, and reported improved communication/evaluation skills. Content delivery preference significantly affected attitudes. Conclusion. Students positively received a flipped team-based learning classroom format, especially those who preferred flipped TBL or mixed content delivery. A minority with preference for traditional teaching style did not enjoy the new format; however, their academic performance did not differ significantly from those who did. PMID:27293234

    The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics. PMID:24761922

    A psychosocial oncology learning needs assessment was developed and offered online to cancer care providers in a variety of settings across all health regions in British Columbia. The purpose was to better understand the psychosocial learning needs of cancer care providers and to use this knowledge to shape continuing education priorities. Respondents' preferred learning formats, access to technology and barriers to accessing psychosocial learning opportunities were also assessed. Cancer care providers including radiation therapists, social workers, dieticians, pharmacists, physicians and nurses in both community and agency settings were surveyed. Two hundred and sixty-seven people completed the survey. Key learning needs identified included cultural aspects of care, symptom management, treating the anxious patient, self-care for the professional, care of elderly patients, basic cancer-related medical issues surrounding care and ethics. Community respondents indicated more needs than agency respondents. On-site training was the most preferred learning format, and time constraints were the biggest barrier to accessing learning opportunities. Participants had access to technology. Next steps include conducting key informant and focus group interviews to determine if interest in a learning need is the same as a relevant knowledge and practice gap. This research suggests that cancer care providers are interested in learning more about the psychosocial issues related to cancer care. PMID:20361284

    Improved cancer survivorship has resulted in a growing number of Canadians affected by cancer and cardiovascular disease. As a consequence, cardio-oncology programs are rapidly emerging to treat cancer patients with de novo and preexisting cardiovascular disease. The primary goal of a cardio-oncology program is to preserve cardiovascular health to allow the timely delivery of cancer therapy and achieve disease-free remission. Multidisciplinary programs in oncology and cardiology have been associated with enhanced patient well-being and improved clinical outcomes. Because of the complex needs of these multisystem patients, a similar model of care is gaining acceptance. The optimal composition of the cardio-oncology team will typically involve support from cardiology, oncology, and nursing. Depending on the clinical scenario, additional consultation from dietetics, pharmacy, and social services might be required. Timely access to consultation and testing is another prerequisite for cardio-oncology programs because delays in treating cardiac complications and nonadherence to prescribed cancer therapy are each associated with poor outcomes. Recommended reasons for referral to cardio-oncology programs include primary prevention for those at high risk for cardiotoxicity and the secondary treatment of new or worsening cardiovascular disease in cancer patients and survivors. Management is multifaceted and can involve lifestyle education, pharmacotherapy, enhanced cardiovascular surveillance, and support services, such as exercise training. The lack of evidence to guide clinical decisions and recommendations in cardio-oncology is a major challenge and opportunity for health care professionals. Large multicentre prospective registries are needed to adequately power risk model calculations and generate hypotheses for novel interventions. PMID:27343743

    Breast cancer is the most common malignant disease in women, and it is not the primary tumor but its metastasis kills most patients with breast cancer. Anti-metastasis therapy based on RNA interference (RNAi) is emerging as one of promising strategies in tumor therapy. However, construction of an efficient delivery system for siRNA is still one of the major challenges. In this work, siRNA against protease-activated receptor-1 (PAR-1) which is a pivotal gene involved in tumor metastasis was conjugated to gold nanorods (AuNRs) via electrostatic interaction and delivered to highly metastatic human breast cancer cells. It was demonstrated that the siRNA oligos were successfully delivered into the cancer cells and mainly located in vesicle-like structures including lysosome. After transfected with the complex of AuNRs and PAR-1 siRNA (AuNRs@PAR-1 siRNA), expression of PAR-1 at both mRNA and protein levels were efficiently down regulated, as evidenced by quantitative real time PCR and flow cytometry analysis, respectively. Transwell migration assay confirmed the decrease in metastatic ability of the cancer cells. The silencing efficiency of the complex was in-between that of TurboFect and Lipofectamine, however, the cytotoxicity of the AuNRs was lower than that of the latter two. Taken together, AuNRs with PAR-1 siRNA are suited for RNAi based anti-metastasis therapy.Breast cancer is the most common malignant disease in women, and it is not the primary tumor but its metastasis kills most patients with breast cancer.

    This study describes the experiences of and barriers for pediatricians in Kentucky in providing behavioral/mental health (B-MH) services in primary care settings. These data will serve as a foundation for improving service delivery. An online survey was completed by 70 pediatricians. Descriptive data are presented. More than 90% of the respondents said that they saw at least one patient a month with 1 of 10 specific B-MH diagnoses. Physicians' comfort with diagnosing and treating disorders varied widely by diagnosis, age-group, and drug classification. Major barriers to providing optimal care were inaccessibility of mental health professionals for consultation and referral, lack of communication, and lack of knowledge. Respondents were more likely to favor consultation and co-location models over an integration model of care delivery. Overall, the authors found that pediatricians are dealing with patients with B-MH problems for which they may not have been adequately trained. Communication and collaboration needs were identified.

    The paucity of skilled manpower in sub-Saharan Africa limits the delivery of effective interventions for the mentally ill. Individuals with mental disorders and their caregivers frequently consult clergy when mental symptoms cause distress. There is an urgent need for collaboration with nonprofessionals in order to improve mental health care delivery and close the widening treatment gap. Using a cross-sectional descriptive method, we explored clergy's (Christian and Muslim) aetiological attributions for common mental illness (schizophrenia and depression) from Benin City, Nigeria, as well as their willingness to collaborate with mainstream mental health services. We observed that a majority of clergy surveyed were able to correctly identify mental illnesses depicted in vignettes, embraced a multifactorial model of disease causation, and expressed willingness to collaborate with mental health care workers to deliver care. Clergy with a longer duration of formal education, prior mental health training, and Catholic/Protestant denomination expressed a greater willingness to collaborate. Educational interventions are urgently required to facilitate this partnership. PMID:24599283

    Full Text Available Abstract Background In recognition of the critical shortage of human resources within health services, community health workers have been trained and deployed to provide primary health care in developing countries. However, very few studies have investigated whether these health workers can provide good quality of care. This study investigated the knowledge and performance of health extension workers (HEWs on antenatal and delivery care. The study also explored the barriers and facilitators for HEWs in the provision of maternal health care. Methods In conducting this research, a cross-sectional study was performed. A total of 50 HEWs working in 39 health posts, covering a population of approximately 195,000 people, were interviewed. Descriptive statistics was used and a composite score of knowledge of HEWs was made and interpreted based on the Ethiopian education scoring system. Results Almost half of the respondents had at least 5 years of work experience as a HEW. More than half (27 (54% of the HEWs had poor knowledge on contents of antenatal care counseling, and the majority (44 (88% had poor knowledge on danger symptoms, danger signs, and complications in pregnancy. Health posts, which are the operational units for HEWs, did not have basic infrastructures like water supply, electricity, and waiting rooms for women in labor. On average within 6 months, a HEW assisted in 5.8 births. Only a few births (10% were assisted at the health posts, the majority (82% were assisted at home and only 20% of HEWs received professional assistance from a midwife. Conclusion Considering the poor knowledge of HEWs, poorly equipped health posts, and poor referral systems, it is difficult for HEWs to play a key role in improving health facility deliveries, skilled birth attendance, and on-time referral through early identification of danger signs. Hence, there is an urgent need to design appropriate strategies to improve the performance of HEWs by enhancing their

    The need for palliative care has never been greater. From being significantly present in only five African countries in 2004, palliative care is now delivered in nearly 50% of African countries; however, less than 5% of people in need receive it. To scale-up palliative care, we need greater knowledge about how different models of palliative care work within different health systems. A case study evaluation was undertaken in Kenya and Malawi to define the models used, contextualize them, and identify challenges, best practices, and transferable lessons for scale-up. Visits were made to seven sites and, using an audit tool, data were collected from program staff, hospital staff, and local stakeholders, and care observed as appropriate. Three models of palliative care service delivery were identified, which supports the existing literature, that is, specialist, district hospital level, and community level. However, in looking further, findings show that the major determinants for each model were a set of philosophical questions and assumptions underpinning each and influencing staff and patient decision-making, planning, and allocation of resources. The health system structure and the beliefs about palliative care determined, and were determined most by, referrals, the patient journey, the centeredness of the model, and role definition and training. The models are also closely associated with the physical setting of services. Understanding how the services have developed because of, and indeed despite the geographical setting and the system level, provides us with a different set of indicators of program structure incorporated into the three models. The analysis of models provides pointers to future planning for palliative care. PMID:25936938

    Preclinical results with various gene therapy strategies indicate significant potential for new cancer treatments. However, many therapeutics fail at clinical trial, often due to differences in tissue physiology between animal models and humans, and tumor phenotype variation. Clinical data relevant to treatment strategies may be generated prior to clinical trial through experimentation using intact patient tissue ex vivo. We developed a novel tumor slice model culture system that is universally applicable to gene delivery methods, using a realtime luminescence detection method to assess gene delivery. Methods investigated include viruses (adenovirus [Ad] and adeno-associated virus), lipofection, ultrasound (US), electroporation and naked DNA. Viability and tumor populations within the slices were well maintained for seven days, and gene delivery was qualitatively and quantitatively examinable for all vectors. Ad was the most efficient gene delivery vector with transduction efficiency >50%. US proved the optimal non-viral gene delivery method in human tumor slices. The nature of the ex vivo culture system permitted examination of specific elements. Parameters shown to diminish Ad gene delivery included blood, regions of low viability and secondary disease. US gene delivery was significantly reduced by blood and skin, while tissue hyperthermia improved gene delivery. US achieved improved efficacy for secondary disease. The ex vivo model was also suitable for examination of tissue-specific effects on vector expression, with Ad expression mediated by the CXCR4 promoter shown to provide a tumor selective advantage over the ubiquitously active cytomegalovirus promoter. In conclusion, this is the first study incorporating patient tissue models in comparing gene delivery from various vectors, providing knowledge on cell-type specificity and examining the crucial biological factors determining successful gene delivery. The results highlight the importance of in

    This study emphasizes the development of a novel surface modified liposome as an anticancer drug nanocarrier. Quaternized N,O-oleoyl chitosan (QCS) was synthesized and incorporated into liposome vesicles, generating QCS-liposomes (Lip-QCS). The Lip-QCS liposomes were spherical in shape (average size diameter 171.5±0.8nm), with a narrow size distribution (PDI 0.1±0.0) and zeta potential of 11.7±0.7mV. In vitro mucoadhesive tests indicated that Lip-QCS possesses a mucoadhesive property. Moreover, the presence of QCS was able to induce the cationic charge on the surface of liposome. Cellular internalization of Lip-QCS was monitored over time, with the results revealing that the cell entry level of Lip-QCS was elevated at 24h. Following this, Lip-QCS were then employed to load cisplatin, a common platinum-containing anti-cancer drug, with a loading efficiency of 27.45±0.78% being obtained. The therapeutic potency of the loaded Lip-QCS was investigated using a 3D spheroid cervical cancer model (SiHa) which highlighted their cytotoxicity and apoptosis effect, and suitability as a controllable system for sustained drug release. This approach has the potential to assist in development of an effective drug delivery system against cervical cancer. PMID:27442151

    Patients in vulnerable population groups suffer disproportionately from cancer. The elimination of cancer disparities is critically important for lessening the burden of cancer. Patient navigator programs have been shown to improve clinical outcomes. Among its provisions relevant to disparities in cancer care, The Patient Protection and Affordability Care Act authorizes continued funding of patient navigator programs. However, given the current economic and political environment, this funding is in jeopardy. This article describes patient navigator programs and summarizes the elements of the health care law that are relevant to these programs. It is vital that the entire oncology community remain committed to leading efforts toward the improvement of cancer care among our most vulnerable patients. PMID:21804070

  16. Fostering maternal and newborn care in India the Yashoda way: does this improve maternal and newborn care practices during institutional delivery?

    Directory of Open Access Journals (Sweden)

    Beena Varghese

    Full Text Available BACKGROUND: The Yashoda program, named after a legendary foster-mother in Indian mythology, under the Norway-India Partnership Initiative was launched as a pilot program in 2008 to improve the quality of maternal and neonatal care at facilities in select districts of India. Yashodas were placed mainly at district hospitals, which are high delivery load facilities, to provide support and care to mothers and newborns during their stay at these facilities. This study presents the results from the evaluation of this intervention in two states in India. METHODS: Data collection methods included in-depth interviews with healthcare providers and mothers and a survey of mothers who had recently delivered within a quasi-experimental design. Fifty IDIs were done and 1,652 mothers who had delivered in the past three months were surveyed during 2010 and 2011. RESULTS: A significantly higher proportion of mothers at facilities with Yashodas (55 percent to 97 percent received counseling on immunization, breastfeeding, family planning, danger signs, and nutrition compared to those in control districts (34 percent to 66 percent. Mothers in intervention facilities were four to five times more likely to receive postnatal checks than mothers in control facilities. Among mothers who underwent cesarean sections, initiation of breastfeeding within five hours was 50 percent higher in intervention facilities. Mothers and families also reported increased support, care and respect at intervention facilities. CONCLUSION: Yashoda as mothers' aide thus seems to be an effective intervention to improve quality of maternal and newborn care in India. Scaling up of this intervention is recommended in district hospitals and other facilities with high volume of deliveries.

    Mulley, Albert G

    2013-09-01

    This paper addresses the fourth theme of the Indiana Global Health Research Working Conference, Clinical Effectiveness and Health Systems Research. It explores geographic variation in health care delivery and health outcomes as a source of learning how to achieve better health outcomes at lower cost. It focuses particularly on the relationship between investments made in capacities to deliver different health care services to a population and the value thereby created by that care for individual patients. The framing begins with the dramatic variation in per capita health care expenditures across the nations of the world, which is largely explained by variations in national wealth. The 1978 Declaration of Alma Ata is briefly noted as a response to such inequities with great promise that has not as yet been realized. This failure to realize the promise of Alma Ata grows in significance with the increasing momentum for universal health coverage that is emerging in the current global debate about post-2015 development goals. Drawing upon work done at Dartmouth over more than three decades, the framing then turns to within-country variations in per capita expenditures, utilization of different services, and health outcomes. A case is made for greater attention to the question of value by bringing better information to bear at both the population and individual levels. Specific opportunities to identify and reduce waste in health care, and the harm that is so often associated with it, are identified by learning from outcome variations and practice variations.
