Non-adherence is common in adolescent and young adult kidney transplant recipients, leading to adverse graft outcomes. The aim of this study was to determine whether adherence to immunosuppressant medications changes during transition from a pediatric to an adult program within the same transplant center. Adherence was assessed for a period of two yr before and two yr after the transfer. Subtherapeutic trough levels of serum tacrolimus and level variability were used as measures of adherence. Twenty-five patients were transitioned between 1996 and 2011 at the median age of 22.3 [IQR 21.6-23.0] yr. Young adults 21-25 yr of age (n = 26) and non-transitioned adolescents 17-21 yr of age (currently followed in the program, n = 24 and those that lost their grafts prior to the transfer, 22) formed the comparison groups. In the transitioned group, adherence prior to the transfer was not significantly different from the adherence after the transfer (p = 0.53). The rate of non-adherence in the group of non-transitioned adolescents who lost their grafts (68%) was significantly higher than in the transitioned group (32%, p = 0.01). In the group of young adults, adherence was not significantly different from the transitioned group (p = 0.27). Thus, transition was not associated with differences in medication adherence in this single-center study. Large-scale studies are needed to evaluate the national data on medication adherence after transfer. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

One particular paradigm of anticancer immunotherapy relies on the administration of (potentially) tumor-reactive immune effector cells. Generally, these cells are obtained from autologous peripheral blood lymphocytes (PBLs) ex vivo (in the context of appropriate expansion, activation and targeting protocols), and re-infused into lymphodepleted patients along with immunostimulatory agents. In spite of the consistent progress achieved throughout the past two decades in this field, no adoptive cell transfer (ACT)-based immunotherapeutic regimen is currently approved by regulatory agencies for use in cancer patients. Nonetheless, the interest of oncologists in ACT-based immunotherapy continues to increase. Accumulating clinical evidence indicates indeed that specific paradigms of ACT, such as the infusion of chimeric antigen receptor (CAR)-expressing autologous T cells, are associated with elevated rates of durable responses in patients affected by various neoplasms. In line with this notion, clinical trials investigating the safety and therapeutic activity of ACT in cancer patients are being initiated at an ever increasing pace. Here, we review recent preclinical and clinical advances in the development of ACT-based immunotherapy for oncological indications. PMID:26451319

Diffusion and adoption of effective evidence-based clinical practices can be slow, especially if complex changes are required to implement new practices. To examine how hospital adherence to quality improvement (QI) methods and hospital engagement with a large-scale QI campaign could facilitate the adoption of an enhanced prevention bundle designed to reduce surgical site infection (SSI) rates after orthopaedic surgery (hip and knee arthroplasty). We conducted telephone interviews with hospital QI leaders from 73 of the 109 hospitals (67% response rate) in five states that participated in Project JOINTS (Joining Organizations IN Tackling SSIs), a QI campaign run by Institute for Healthcare Improvement (IHI). Using QI methods grounded in the IHI Model for Improvement, this campaign encouraged hospitals to implement an enhanced SSI prevention bundle. Hospital QI leaders reported on their hospital's adherence to the Project JOINTS QI methods; their level of engagement with Project JOINTS activities; and adoption of the SSI prevention bundle components. Interview data were analysed quantitatively and qualitatively. Both adherence to the QI methods and hospital engagement were positively associated with complete bundle adoption. Hospital engagement, especially the use of project materials and tools, was also positively associated with the initiation of and improved adherence to individual bundle components. Our findings suggest that greater adherence to the QI methods and active hospital engagement in a QI campaign facilitate adoption of evidence-based patient safety bundles in orthopaedic practice.

Practicing surgeons commonly learn new procedures and techniques by attending a "hands-on" course, though trainings are often ineffective at promoting subsequent procedure adoption in practice. We describe implementation of a new program with the SAGES All Things Hernia Hands-On Course, Acquisition of Data for Outcomes and Procedure Transfer (ADOPT), which employs standardized, proven teaching techniques, and 1-year mentorship. Attendee confidence and procedure adoption are compared between standard and ADOPT programs. For the pilot ADOPT course implementation, a hands-on course focusing on abdominal wall hernia repair was chosen. ADOPT participants were recruited among enrollees for the standard Hands-On Hernia Course. Enrollment in ADOPT was capped at 10 participants and limited to a 2:1 student-to-faculty ratio, compared to the standard course 22 participants with a 4:1 student-to-faculty ratio. ADOPT mentors interacted with participants through webinars, phone conferences, and continuous email availability throughout the year. All participants were asked to provide pre- and post-course surveys inquiring about the number of targeted hernia procedures performed and related confidence level. Four of 10 ADOPT participants (40%) and six of 22 standard training participants (27%) returned questionnaires. Over the 3 months following the course, ADOPT participants performed more ventral hernia mesh insertion procedures than standard training participants (median 13 vs. 0.5, p = 0.010) and considerably more total combined procedures (median 26 vs. 7, p = 0.054). Compared to standard training, learners who participated in ADOPT reported greater confidence improvements in employing a components separation via an open approach (p = 0.051), and performing an open transversus abdominis release, though the difference did not achieve statistical significance (p = 0.14). These results suggest that the ADOPT program, with standardized and structured teaching

Cardiovascular disease is the most common cause of death in Western countries. Physician adherence to guidelines is often suboptimal, resulting in impaired patient outcome and prognosis. Multiple studies have been conducted to evaluate patterns and the influencing factors of patient adherence, but little is known about factors influencing physician guideline adherence. This review aims to identify factors influencing physician guideline adherence relevant to cardiology and to provide insights and suggestions for future improvement. Physician adherence was measured as adherence to standard local medical practice and applicable guidelines. Female gender and older age had a negative effect on physician guideline adherence. In addition, independent of the type of heart disease, physicians without cardiologic specialization were linked to physician noncompliance. Also, guideline adherence in primary care centers was at a lower level compared to secondary or tertiary care centers. The importance of guideline adherence increases as patients age, and complex diseases and comorbidity arise. Appropriate resources and interventions, taking important factors for nonadherence in account, are necessary to improve guideline adoption and adherence in every level of the chain. This in turn should improve patient outcome.

The objective of the present study was to gain an understanding of the organizational characteristics and processes in two child-care centres that may influence adoption of the Alberta Nutrition Guidelines for Children and Youth (ANGCY). In-depth qualitative case studies. Data were collected through direct observations, key informant interviews and field notes. Diffusion of Innovations theory guided the evaluation and intrinsic case analysis. Two urban child-care centres in Edmonton, Alberta, Canada identified as exemplary early adopter cases. Ten key informants comprised of directors, junior and senior staff members participated in interviews. Organizational processes such as leadership, networking and knowledge brokering, health champions and organizational culture positively influenced adoption behaviour in child-care centres. A key determinant influencing organizational behaviour within both centres was the directors' strong leadership. Acceptance of and adherence to the guidelines were facilitated by organizational factors, such as degree of centralization, formalization and complexity, level of staff training and education. Knowledge brokering by directors was important for transferring and exchanging information across the centre. All child-care staff embraced their informal role as health champions as essential to supporting guideline adherence and encouraging healthy food and eating environments. Organizational processes and characteristics such as leadership, knowledge brokering and networking, organizational culture and health champions played an important role in the adoption of nutrition guidelines in child-care centres. The complex interplay of decision making, organization of work and specialization of roles influenced the extent to which nutrition guidelines were adopted.

In response to evolving policies and conditions, hospitals have increased health information technology (HIT) adoption and strived to improve hospital-physician integration. While evidence suggests that both HIT and integration confer independent benefits, when combined, they may provide complementary means to achieve high performance or overlap to offset each other's contribution. We explore this relationship in the context of hospital adherence to evidence-based practices (EBPs). Using the American Hospital Association's Annual and IT Supplement surveys, and Centers for Medicare and Medicaid Services's Hospital Compare, we estimate the independent relationships and interactions between HIT and hospital-physician integration with respect to EBP adherence. HIT adoption and tight (but not loose) integration are independently associated with greater adherence to EBPs. The interaction between HIT adoption and tight integration is negative, consistent with an offsetting association between HIT adoption and integration in their relationship to EBP adherence. This finding reveals the need to be aware of potential substitutive effects from simultaneous pursuit of multiple approaches to performance improvement. © The Author(s) 2016.

The purpose of this study was 2-fold: (1) to explore the transfer of responsibility of medical tasks from parent to child during the transition to adolescence, and (2) to examine the associations between family functioning and medical adherence in youth with spina bifida. Seventy families of children with spina bifida participated in this study. Data were collected during family interaction sessions by using questionnaires completed by mothers, fathers, youth, teachers and health professionals. Findings suggest that responsibility for medical regimens transfers gradually from parent to child over time. Additionally, family conflict and cohesion were correlated with medical adherence. Finally, family conflict over medical issues was related to a decrease in medical adherence over time. Results suggest that as youth take more responsibility over their medical regimens, family conflict regarding medical issues becomes a contributor to their adherence behaviors. Interventions that target family conflict may facilitate adherence behaviors.

The Danish Adoption Register was established in 1963-1964 to explore the genetic and environmental contribution to familial aggregation of schizophrenia. The register encompass information on all 14,425 non-familial adoptions of Danish children legally granted in Denmark 1924-1947. It includes name and date of birth of each adoptee and his or her biological and adoptive parents, date of transfer to adoptive parents and date of formal adoption. The linkage to biological and adoptive parents is close to complete, even biological fathers are registered for 91.4% of the adoptees. Adoption registers are a unique source allowing disentangling of genetic and familial environmental influences on traits, risk of diseases, and mortality.

To understand market managers' level of communication and use of technology that might influence decision to adopt Electronic Benefits Transfer (EBT) at farmers' markets. Cross-sectional study using the Theory of Diffusion of Innovation. Electronic survey administered in midwest states of Illinois, Michigan, and Wisconsin. Farmers' market managers in Illinois, Michigan, and Wisconsin. Information on EBT adoption, market managers' communication, and technology use. Binary logistic regression analysis with EBT adoption as the dependent variable and frequency of technology use, partnership with organizations, farmers' market association (FMA) membership, Facebook page and Web site for the market, and primary source of information as independent variables. Chi-square tests and ANOVA were used to compare states and adopter categories. Logistic regression results showed that the odds of adopting EBT was 7.5 times higher for markets that had partnership with other organizations. Compared with non-adopters, a significantly greater number of early adopters had partnership, FMA membership, and a Facebook page and Web site for market, and reported to a board of directors. Markets that had partnership, FMA membership, a Facebook page and Web site, and mandatory reporting to a board of directors were important factors that influenced EBT adoption at midwest farmers' markets.

Transfer of adoptive immunity to tuberculosis in mice

International Nuclear Information System (INIS)

Lefford, M.J.

1975-01-01

A system is described for studying adoptive immunity to tuberculosis in syngeneic mice. Donor mice were immunized with 10 4 BCG intravenously, and lymphoid cells were harvested 28 days later. Adoptive immunity was measured in recipient mice in terms of the inhibition of growth of BCG in the liver and spleen following intravenous injection. Adoptive immunity was expressed optimally when recipients were sublethally irradiated (500 R), challenged with 10 4 to 10 5 viable organisms, and given sensitized lymphoid cells intravenously. Adoptive immunity was not manifest until 14 days after challenge and was effective against Mycobacterium tuberculosis H37Rv as well as BCG. Immunity could be conferred by spleen, lymph node, peritoneal exudate, and resident peritoneal (washout) cells. The lymphoid cells conferring immunity were shown to be thymus-dependent lymphocytes by virtue of their nonadherence to glass wool and sensitivity to anti-theta serum plus complement. The sensitized cells were relatively susceptible to both in vitro and in vivo x irradiation

In addition to conventional therapies, several new strategies have been proposed for modulating autoimmune diseases, including the adoptive transfer of immunological cells. In this context, dendritic cells (DCs) appear to be one of the most promising treatments for autoimmune disorders. The present study aimed to evaluate the effects of adoptive transfer of DCs obtained from both naïve and ovalbumin (OVA)-tolerant mice on the severity of TNBS induced colitis and analyze the eventual protective mechanisms. To induce oral tolerance, BALB/c mice were fed 4mg/mL OVA solution for seven consecutive days. Spleen DCs were isolated from tolerant (tDC) and naïve (nDC) mice, and then adoptively transferred to syngeneic mice. Three days later, colitis was induced in DC treated mice by intrarectal instillation of 100μg2,4,6-trinitrobenzenesulfonic acid (TNBS) dissolved in 50% ethanol. Control subjects received only intrarectal instillation of either TNBS solution or a vehicle. Five days later, mice from all groups were euthanized and examined for physiological and immunological parameters. Regarding the phenotype, we observed that the frequencies of CD11+ MHC II+ and CD11+ MHCII+ CD86+ cells were significantly lower in DCs isolated from tolerant mice than in those from naive mice. However, pretreatment with both types of DCs was able to significantly reduce clinical signs of colitis such as diarrhea, rectal prolapse, bleeding, and cachexia, although only treatment with tDCs was able to prevent weight loss from instillation of TNBS. In vitro proliferation of spleen cells from mice treated with either type of DCs was significantly lower than that observed in splenic cell cultures of naïve mice. Although no significant difference was observed in the frequencies of Treg cells in the experimental groups, the frequency of Th17+CD4+cellsand the secretion of IL-17 were more reduced in the cultures of spleen cells from mice treated with either type of DCs. The levels of IL-9 and IFN

Adherence of fluid interfaces and colloidal aggregation in emulsions

International Nuclear Information System (INIS)

Poulin, Philippe

1995-01-01

This research thesis addresses some aspects of the behaviour of emulsions in which droplets are adhesive, and are thus characterised by their ability to stick to one another or on surfaces. The objective is also to identify various adhesive systems while describing their behaviour in order to start to build up a rationale of these phenomena. The author mainly focuses on the adherence of single layers of adsorbed surfactants: by inducing and controlling this adherence, it is possible to make the droplets stick. After a brief presentation of the wetting phenomenon and of the adherence of emulsion droplets, the author presents theoretical backgrounds of adherence, and describes the thermodynamics of liquid films. He presents the general approach which has been adopted to search for and control adherence phenomena in emulsions, and outlines challenges and difficulties related to the use of adhesive particles in industrial applications. A method of measurement of the contact angle between droplets of some tens of microns is described. In the next part, the author reports the characterisation of adherence properties of different emulsions: measurement of adherence energy with respect to some parameters by using contact angle measurements, study of mixed systems (mixtures of surfactants) to illustrate the applicability to industrial formulas. In a last part, the author reports measurements of film thickness between stuck droplets by using experiments of small angle neutron scattering [fr

Plasmodium chabaudi in mice. Adoptive transfer of immunity with enriched populations of spleen T and B lymphocytes

Thymectomized NIH and C57BL mice were more susceptible to Plasmodium chabaudi than controls, indicating a role for T cells in acquired immunity to the parasite. Enriched populations of T and B cells were prepared from the spleens of immune mice using nylon-wool columns, and were adoptively transferred to syngeneic non-irradiated mice or mice irradiated with 600 or 800 rad. Some immunity could usually be transferred with immune T, B and glass-wool (g.w.) filtered spleen cell populations. In the heavily irradiated mice g.w. filtered immune spleen cells gave the best protection and the immune T cells the least. Preliminary attempts to show synergistic activity between immune T and B cells in irradiated mice were not successful. (author)

Vulvovaginal candidiasis is a mucosal infection affecting many women, but the immune mechanisms operating against Candida albicans at the mucosal level remain unknown. A rat model was employed to further characterize the contribution of B and T cells to anti-Candida vaginal protection. Particularly, the protective role of vaginal B cells was studied by means of adoptive transfer of vaginal CD3(-) CD5(+) IgM(+) cells from Candida-immunized rats to naïve animals. This passive transfer of B cells resulted into a number of vaginal C. albicans CFU approximately 50% lower than their controls. Sorted CD3(-) CD5(+) IgM(+) vaginal B lymphocytes from Candida-infected rats proliferated in response to stimulation with an immunodominant mannoprotein (MP) antigen of the fungus. Importantly, anti-MP antibodies and antibody-secreting B cells were detected in the supernatant and cell cultures, respectively, of vaginal B lymphocytes from infected rats incubated in vitro with vaginal T cells and stimulated with MP. No such specific antibodies were found when using vaginal B cells from uninfected rats. Furthermore, inflammatory and anti-inflammatory cytokines, such as interleukin-2 (IL-2), IL-6 and IL-10, were found in the supernatant of vaginal B cells from infected rats. These data are evidence of a partial anti-Candida protective role of CD3(-) CD5(+) IgM(+) vaginal B lymphocytes in our experimental model.

CpG Oligodeoxynucleotides Enhance the Efficacy of Adoptive Cell Transfer Using Tumor Infiltrating Lymphocytes by Modifying the Th1 Polarization and Local Infiltration of Th17 Cells

Full Text Available Adoptive cell transfer immunotherapy using tumor infiltrating lymphocytes (TILs was an important therapeutic strategy against tumors. But the efficacy remains limited and development of new strategies is urgent. Recent evidence suggested that CpG-ODNs might be a potent candidate for tumor immunotherapy. Here we firstly reported that CpG-ODNs could significantly enhance the antitumor efficacy of adoptively transferred TILs in vivo accompanied by enhanced activity capacity and proliferation of CD8+ T cells and CD8+ T cells, as well as a Th1 polarization immune response. Most importantly, we found that CpG-ODNs could significantly elevate the infiltration of Th17 cells in tumor mass, which contributed to anti-tumor efficacy of TILs in vivo. Our findings suggested that CpG ODNs could enhance the anti-tumor efficacy of adoptively transferred TILs through modifying Th1 polarization and local infiltration of Th17 cells, which might provide a clue for developing a new strategy for ACT based on TILs.

Ineffective communication of infection control requirements during transitions of care is a potential cause of non-compliance with infection control precautions by healthcare personnel. In this study, interventions to enhance communication during inpatient transfers between wards and radiology were implemented, in the attempt to improve adherence to precautions during transfers. Two interventions were implemented, comprising (i) a pre-transfer checklist used by radiology porters to confirm a patient's infectious status; (ii) a coloured cue to highlight written infectious status information in the transfer form. The effectiveness of the interventions in promoting adherence to standard precautions by radiology porters when transporting infectious patients was evaluated using a randomised crossover trial at a teaching hospital in Australia. 300 transfers were observed over a period of 4 months. Compliance with infection control precautions in the intervention groups was significantly improved relative to the control group (p group was 38%. Applying the coloured cue resulted in a compliance rate of 73%. The pre-transfer checklist intervention achieved a comparable compliance rate of 71%. When both interventions were applied, a compliance rate of 74% was attained. Acceptability of the coloured cue was high, but adherence to the checklist was low (40%). Simple measures to enhance communication through the provision of a checklist and the use a coloured cue brought about significant improvement in compliance with infection control precautions by transport personnel during inpatient transfers. The study underscores the importance of effective communication in ensuring compliance with infection control precautions during transitions of care.

The Staphylococcus aureus extracellular adherence protein (Eap) adopts an elongated but structured conformation in solution.

The extracellular adherence protein (Eap) of Staphylococcus aureus participates in a wide range of protein-protein interactions that facilitate the initiation and dissemination of Staphylococcal disease. In this report, we describe the use of a multidisciplinary approach to characterize the solution structure of full-length Eap. In contrast to previous reports suggesting that a six-domain isoform of Eap undergoes multimerization, sedimentation equilibrium analytical ultracentrifugation data revealed that a four-domain isoform of Eap is a monomer in solution. In vitro proteolysis and solution small angle X-ray scattering studies both indicate that Eap adopts an extended conformation in solution, where the linkers connecting sequential EAP modules are solvent exposed. Construction of a low-resolution model of full-length Eap using a combination of ab initio deconvolution of the SAXS data and rigid body modeling of the EAP domain crystal structure suggests that full-length Eap may present several unique concave surfaces capable of participating in ligand binding. These results also raise the possibility that such surfaces may be held together by additional interactions between adjacent EAP modules. This hypothesis is supported by a comparative Raman spectroscopic analysis of full-length Eap and a stoichiometric solution of the individual EAP modules, which indicates the presence of additional secondary structure and a greater extent of hydrogen/deuterium exchange protection in full-length Eap. Our results provide the first insight into the solution structure of full-length Eap and an experimental basis for interpreting the EAP domain crystal structures within the context of the full-length molecule. They also lay a foundation for future studies into the structural and molecular bases of Eap-mediated protein-protein interactions with its many ligands.

Adolescent and young adult kidney transplant recipients have worse graft outcomes than older and younger age groups. Difficulties in the process of transition, defined as the purposeful, planned movement of adolescents with chronic health conditions from child to adult-centered health care systems, may contribute to this. Improving the process of transition may improve adherence post-transfer to adult care services. The purpose of this study is to investigate whether a kidney transplant transfer clinic for adolescent and young adult kidney transplant recipients transitioning from pediatric to adult care improves adherence post-transfer. We developed a joint kidney transplant transfer clinic between a pediatric kidney transplant program, adult kidney transplant program, and adolescent medicine at two academic health centers. The transfer clinic facilitated communication between the adult and pediatric transplant teams, a face-to-face meeting of the patient with the adult team, and a meeting with the adolescent medicine physician. We compared the outcomes of 16 kidney transplant recipients transferred before the clinic was established with 16 patients who attended the clinic. The primary outcome was a composite measure of non-adherence. Non-adherence was defined as either self-reported medication non-adherence or displaying two of the following three characteristics: non-attendance at clinic, non-attendance for blood work appointments, or undetectable calcineurin inhibitor levels within 1 year post-transfer. The two groups were similar at baseline, with non-adherence identified in 43.75 % of patients. Non-adherent behavior in the year post-transfer, which included missing clinic visits, missing regular blood tests, and undetectable calcineurin inhibitor levels, was significantly lower in the cohort which attended the transfer clinic (18.8 versus 62.5 %, p = 0.03).

Poor retention in care and non-adherence to antiretroviral therapy (ART) continue to undermine the success of HIV treatment and care programmes across the world. There is a growing recognition that multifaceted interventions - application of two or more adherence-enhancing strategies - may be useful to improve ART adherence and retention in care among people living with HIV/AIDS. Empirical evidence shows that multifaceted interventions produce better results than interventions based on a singular perspective. Nevertheless, the bundle of mechanisms by which multifaceted interventions promote ART adherence are poorly understood. In this paper, we reviewed theories on ART adherence to identify candidate/potential mechanisms by which the adherence club intervention works. We searched five electronic databases (PubMed, EBSCOhost, CINAHL, PsycARTICLES and Google Scholar) using Medical Subject Headings (MeSH) terms. A manual search of citations from the reference list of the studies identified from the electronic databases was also done. Twenty-six articles that adopted a theory-guided inquiry of antiretroviral adherence behaviour were included for the review. Eleven cognitive and behavioural theories underpinning these studies were explored.

Adoptive transfer of T cells is a promising cancer therapy and expression of chimeric antigen receptors can enhance tumour recognition and T-cell effector functions. The programmed death protein 1 (PD1) receptor is a prospective target for a chimeric antigen receptor because PD1 ligands are expressed on many cancer types, including lymphoma. Therefore, we developed a murine chimeric PD1 receptor (chPD1) consisting of the PD1 extracellular domain fused to the cytoplasmic domain of CD3ζ. Additionally, chimeric antigen receptor therapies use various co-stimulatory domains to enhance efficacy. Hence, the inclusion of a Dap10 or CD28 co-stimulatory domain in the chPD1 receptor was compared to determine which domain induced optimal anti-tumour immunity in a mouse model of lymphoma. The chPD1 T cells secreted pro-inflammatory cytokines and lysed RMA lymphoma cells. Adoptive transfer of chPD1 T cells significantly reduced established tumours and led to tumour-free survival in lymphoma-bearing mice. When comparing chPD1 receptors containing a Dap10 or CD28 domain, both receptors induced secretion of pro-inflammatory cytokines; however, chPD1-CD28 T cells also secreted anti-inflammatory cytokines whereas chPD1-Dap10 T cells did not. Additionally, chPD1-Dap10 induced a central memory T-cell phenotype compared with chPD1-CD28, which induced an effector memory phenotype. The chPD1-Dap10 T cells also had enhanced in vivo persistence and anti-tumour efficacy compared with chPD1-CD28 T cells. Therefore, adoptive transfer of chPD1 T cells could be a novel therapy for lymphoma and inclusion of the Dap10 co-stimulatory domain in chimeric antigen receptors may induce a preferential cytokine profile and T-cell differentiation phenotype for anti-tumour therapies. © 2017 John Wiley & Sons Ltd.

Exploring ‘generative mechanisms’ of the antiretroviral adherence club intervention using the realist approach: a scoping review of research-based antiretroviral treatment adherence theories

Full Text Available Abstract Background Poor retention in care and non-adherence to antiretroviral therapy (ART continue to undermine the success of HIV treatment and care programmes across the world. There is a growing recognition that multifaceted interventions – application of two or more adherence-enhancing strategies – may be useful to improve ART adherence and retention in care among people living with HIV/AIDS. Empirical evidence shows that multifaceted interventions produce better results than interventions based on a singular perspective. Nevertheless, the bundle of mechanisms by which multifaceted interventions promote ART adherence are poorly understood. In this paper, we reviewed theories on ART adherence to identify candidate/potential mechanisms by which the adherence club intervention works. Methods We searched five electronic databases (PubMed, EBSCOhost, CINAHL, PsycARTICLES and Google Scholar using Medical Subject Headings (MeSH terms. A manual search of citations from the reference list of the studies identified from the electronic databases was also done. Twenty-six articles that adopted a theory-guided inquiry of antiretroviral adherence behaviour were included for the review. Eleven cognitive and behavioural theories underpinning these studies were explored. We examined each theory for possible ‘generative causality’ using the realist evaluation heuristic (Context-Mechanism-Outcome configuration, then, we selected candidate mechanisms thematically. Results We identified three major sets of theories: Information-Motivation-Behaviour, Social Action Theory and Health Behaviour Model, which explain ART adherence.

The local environment authority of Cundinamarca (Car) through Proca (Soil and Water Conservation Program), has been working in the control of the erosion under the preventive approach, by means of the technological transference of the conservation agriculture. In the present study, using ethnographic instruments, including 44 surveys and structured interviews with 54 farmers (out of 79) and 15 surveys with local officials of PROCAR, the degree of adoption of the conservation agriculture in two user groups of the PROCAS settled down in the municipalities of Nemocon (Cundinamarca) and Caldas (Boyaca) was studied. Using like criterion the number of principles of the applied agriculture of conservation indeed, one was that in Nemocon the null (36.84%) and low adoption (31.57%) predominates whereas in Caldas a 72% of users with high degree of adoption exist. The differences found in the adoption degree are explained for many reasons: in the biophysical issues, significant agroecologic advantages for Caldas exist. In the economic issues, the own financial limitations of the small farmers and the influence of economic activities different from the farmers, limited the adoption in both municipalities. In the social issues are very important the personal initiative, the community participation and the institutional intervention through the technical consultant's office (in special the attitude of the adviser) and the time of implementation of the Checua Project in each zone. In the technological issues, the adaptation of the technology to the local conditions is determining, as well as in the symbolic issues it is it the relation of the farmer with its surroundings.

The authors previously reported that the adoptive transfer of lymphokine-activated killer (LAK) cells plus repetitive injections of recombinant interleukin 2 (IL 2) produced a marked reduction in established pulmonary metastases from a variety of murine sarcomas. The requirement for the exogenous administration of IL 2 prompted a subsequent examination of the role of IL 2 in the in vivo function of transferred LAK cells. The in vivo proliferation and migration patterns of lymphoid cells in C57BL/6 mice were examined after i.v. transfer of LAK cells alone, i.p. injection of IL 2 alone, or the combination of LAK cells and IL 2. A model for in vivo labeling of the DNA of dividing cells was used in which mice were injected with 5-[ 125 I]-iodo-2'-deoxyuridine ( 125 IUdR) and, 20 hr later, their tissues were removed and were counted in a gamma analyzer. A proliferation index (PI) was calculated by dividing the mean cpm of organs of experimentally treated mice by the mean cpm of organs of control mice. In animals given LAK cells alone, the lungs and liver demonstrated little if any uptake of 125 IUdR above saline-treated controls, whereas the same organs of mice receiving 6000 U of IL 2 alone displayed higher radiolabel incorporation. When mice were given LAK cells plus 6000 U of IL 2, their tissues showed an additional increase in 125 IUdR uptake

Full Text Available Regular physical activity (PA is a key element in the prevention and management of type 2 diabetes mellitus (T2DM. Participation in regular PA improves blood glucose control and can prevent or delay T2DM and its complications, along with positively affecting lipids, blood pressure, cardiovascular events, mortality, and quality of life. However, most people with T2DM are not active and show poor adherence. This paper reviews the possible barriers to PA and strategies to improve the adherence to PA. Based on the currently available literature, it is concluded that self-efficacy and social support from family, friends, and health care providers play the important role in adoption and maintenance of regular PA. Here we also highlight some new modern and innovative interventions that facilitate exercise participation and improve the adherence.

further analyzed to identify strategies used to improve medication adherence. This identified three broad categories of adherence strategies, reminder, behavioral, and educational. A total of 250 apps utilized a single method, 149 apps used two methods, and only 22 apps utilized all three methods. To our knowledge, this is the first study to systematically review all available medication adherence apps on the two largest app repositories. The results demonstrate a concerning lack of HCP involvement in app development and evidence base of effectiveness. More collaboration is required between relevant stakeholders to ensure development of high quality and relevant adherence apps with well-powered and robust clinical trials investigating the effectiveness of these interventions. A sound evidence base will encourage the adoption of effective adherence apps, and thus improve patient welfare in the process. ©Imran Ahmed, Niall Safir Ahmad, Shahnaz Ali, Shair Ali, Anju George, Hiba Saleem Danish, Encarl Uppal, James Soo, Mohammad H Mobasheri, Dominic King, Benita Cox, Ara Darzi.

Full Text Available BACKGROUND The Million Death Study Collaborators in the British Medical Journal have estimated that the people living with HIV/AIDS population to be between 1.4-1.6 million. Development of Antiretroviral Therapy (ART has been one of the dramatic advances in the history of medicine. Among several factors that can affect the ART outcome, adherence to the ART has been cited as a major factor associated with poor outcomes. For ART to have maximum effect greater than 95%, adherence has been suggested. Additionally, non adherence to ART is a major cause of HIV drug resistance. Especially, in the Indian context, adherence to ART is very important due to the sheer number of HIV/AIDS cases, the socioeconomic status, diversity of the population and regions. That is, the socioeconomic challenges faced by patients contribute to nonadherence to ART in India. With this background, this study was done with the primary objective of assessing the level of adherence to the given regimen of ART as per the NACO guidelines and factors influencing adherence. MATERIALS AND METHODS This is a prospective patient record-based study conducted in the Antiretroviral Therapy Centre at MKCG Medical College, Berhampur, from January 2016 to June 2016. Simple random sampling technique was used to select 150 patients’ records from the ART Centre of the medical college. The data was collected in a predesigned case record form from the patient card available at antiretroviral therapy centre. The patients were followed up through the patient card for six months from their recruitment. The adherence to treatment was evaluated using the adherence score adopted by NACO where a score of 1, 2 and 3 implied that 95%, 80-95% and 95% medication taken. Persons with primary education, married individuals and persons without employment had better improvement in adherence score than other groups. Anaemia was the predominant adverse drug reaction encountered. CONCLUSION The findings of this

Adherence to medication regimens is a crucial factor in seizure-freedom and well-being for people with epilepsy. In contrast, taking medication inconsistently increases the risk of not only seizures and their adverse effects, but drug side-effects and unnecessary modifications to treatment plans. Epilepsy is prevalent across all age groups and we have been slow to utilise both the technologies and psychologies derived from computer gaming. Gaming has broken through to the mainstream and is no longer the preserve of younger males, mirroring the adoption of smart-phones. 'Gamification' motivates users into engaging in an activity with a higher intensity and duration. Introducing gaming elements into a non-gaming context has the potential to transform routine tasks into more enjoyable and motivating experiences. This has been exploited by marketing executives, but also has clear uses in a healthcare setting too. We discuss how previously published frameworks could be employed to help people with epilepsy adhere to medication regimens to create a patient-focussed, modifiable and fun experience.

Full Text Available Previously, the mouse A20 B-cell lymphoma engineered to express hemagglutinin (HA antigen (A20HA was used as a systemic tumor model. In this work, we used the A20HA cells as a brain tumor. HA-specific CD4+ T cells were transferred intravenously in a tail vein 5 days after A20HA intracranial inoculation and analyzed on days 2, 9, and 16 after the adoptive transfer by different methods. The transferred cells demonstrated state of activation as early as day 2 after the adoptive transfer and most the of viable HA-specific cells became anergic on day 16. Additionally, symptoms of systemic immunosuppression were observed in mice with massive brain tumors at a late stage of the brain tumor progression (days 20–24 after the A20HA inoculation. Despite that, a deal of HA-specific CD4+ T cells kept the functional activity even at the late stage of A20HA tumor growth. The activated HA-specific CD4+ T cells were found also in the brain of brain-tumor-bearing mice. These cells were still responding to reactivation with HA-peptide in vitro. Our data support an idea about sufficient role of both the tumor-specific and -nonspecific mechanisms inducing immunosuppression in cancer patients.

Full Text Available While major depression is considered a frequent mental illness there are ongoing reports of high non-adherence to antidepressant medications which places suffers at high risk for relapse, recurrence, or greater impairment,. The World Health Organization (WHO defines adherence as the extent to which a person′s behavior (e.g. taking medications can align with the agreed recommendations of a health care provider. Unfortunately while patient may recognize the importance of adherence to antidepressant medications the majority of patients do not adhere to their prescribed antidepressants. Some of the factors that may contribute to or lead to non-adherence include knowingly or unknowingly missing doses, taking extra doses, delaying administration times, or taking drug holidays. Pharmacists have the unique ability to deter non-adherence through the performance of continuous assessment and monitoring of adherence in this population given these accessibility. Additionally, pharmacists are able to develop therapeutic alliances with patients that can help to increase the likelihood of achieving positive patient outcomes. Antidepressant non-adherence can be viewed as a significant public health concern so it is important for patients to be educated about the importance of adherence, and health care professionals should be aware of factors or patient characteristics that can serve as barriers to non-adherence.

A 77-year-old male patient with malignant melanoma was treated by fast neutron therapy and immunotherapy. Total dose of fast neutron applied to the primary lesion was 1905 cGy per 21 fractionation for 46 days. For adoptive immunotherapy, lymphocytes were collected from the peripheral blood drawn from the patient 2 days after the injection of cyclophosphamide. T cells were further purified by passing the lymphocytes through nylon wool. Cytotoxic T cells were induced by incubating the T cells mixed with allogeneic malignant melanoma cells and a small number of patient's adherent cells, and activated with recombinant interleukin-2 (γ IL-2). Our patient and the patient from whom stimulating melanoma cells were derived shared A locous 24 and B locous 51 of MHC class I antigens in common. Thus prepared cytotoxic T cells were inoculated to the patient via the maxillary artery, 3 to 4 times a week for one month. Total amount of cells transferred was 5.6 x 10 8 (97% lymphocytes). Primary lesion reduced markedly by the therapies. During adoptive immunotherapy, increase in natural killer cells and decrease in both suppressor/inducer T-cells and macrophages were observed. However, lung metastases appeared 3 months after adoptive immunotherapy. While the nonspecific immunotherapy (OK-432 injection) was being conducted thereafter, growth of the metastatic lesions of the lung was kept gentle but became obvious after the suspension of the treatment.

Full Text Available Binary logit regression model of econometrics was used to identify the factors affecting adoption of recommended agricultural technology by the commercial farmers of Nepal. A survey was carried out in 2012 in 120 households from Kavre district, Nepal. The objective was to appraise factors affecting adoption of recommended technology of cauliflower, finding out the level of adoption, identifying the constraints of cauliflower cultivation, assessing the perceived level of satisfaction and studying the relationship of certain selected variables on the adoption. Education, Occupation, contact with Personal Localite sources of information, Group membership and Experience were the most influencing factors for adoption of recommended technology. Though, other factors were not strong enough to contribute significantly but indirectly influence the adoption decision of farmers as combined effects. Occupation was found as negatively associated. Landholding size was strongly and positively influencing among the non significant factors. The level of satisfaction and the constraints of cauliflower production were also identified. Transfer of technology will be effective if and only if the client adopts the technology. For an effective transfer of technology, it is better to go for activities for the welfare of the socioeconomic factors of the farmers.

During the last decade, the field of cancer immunotherapy has been entirely transformed by the development of new and more effective treatment modalities with impressive response rates and the prospect of long survival. One of the major breakthroughs is adoptive cell transfer (ACT) based on autologous T cells derived from tumor-infiltrating lymphocytes (TILs). TIL-based ACT is a highly personalized cancer treatment. T cells are harvested from autologous fresh tumor tissues, and after ex vivo activation and extensive expansion, are reinfused to patients. TIL-based therapies have only been offered in small phase I/II studies in a few centers given the highly specialized care required, the complexity of TIL production and the very intensive nature of the three-step treatment protocol. The treatment includes high-dose lymphodepleting chemotherapy, the infusion of the expanded and activated T cells and interleukin-2 (IL-2) injections to increase survival of the T cells. Despite the limited data on ACT, the small published studies consistently confirm an impressive clinical response rate of up to 50% in metastatic melanoma patients, including a significant proportion of patients with durable complete response. These remarkable results justify the need for larger clinical trials in other solid tumors, including gynecologic malignancies. In this review we provide an overview of the current clinical results, future applications of TIL-based ACT in gynecologic malignancies, and on risks and challenges associated with modern T cell therapy.

Carcinoembryonic antigen (CEA) is a cell surface antigen highly expressed in various cancer cell types and in healthy tissues. It has the potential to be a target for chimeric antigen receptor (CAR)-modified T-cell therapy; however, the safety of this approach in terms of on-target/off-tumor effects needs to be determined. To address this issue in a clinically relevant model, we used a mouse model in which the T cells expressing CEA-specific CAR were transferred into tumor-bearing CEA-transgenic (Tg) mice that physiologically expressed CEA as a self-antigen. The adoptive transfer in conjunction with lymphodepleting and myeloablative preconditioning mediated significant tumor regression but caused weight loss in CEA-Tg, but not in wild-type mice. The weight loss was not associated with overt inflammation in the CEA-expressing gastrointestinal tract but was associated with malnutrition, reflected in elevated systemic levels of cytokines linked to anorexia, which could be controlled by the administration of an anti-IL-6 receptor monoclonal antibody without compromising efficacy. The apparent relationship between lymphodepleting and myeloablative preconditioning, efficacy, and off-tumor toxicity of CAR-T cells would necessitate the development of CEA-specific CAR-T cells with improved signaling domains that require less stringent preconditioning for their efficacy. Taken together, these results suggest that CEA-specific CAR-based adoptive T-cell therapy may be effective for patients with CEA + solid tumors. Distinguishing the fine line between therapeutic efficacy and off-tumor toxicity would involve further modifications of CAR-T cells and preconditioning regimens.

Perspectives Regarding Adherence to Prescribed Treatment in Highly Adherent HIV-Infected Gay Men.

Brion, John M; Menke, Edna M

2008-01-01

Focus group methodology was used to describe the medication adherence experience of 24 HIV-infected gay men who reported being adherent to their medication regimens. A conceptualization of medication adherence as an evolving process consisted of challenges to adherence (learning the diagnosis, starting the medications, struggling with the medications, dealing with side effects, coping with stigma) as well as those factors supportive of adherence (believing in medications, finding motivating factors, using reminders, depending on others, owning the disease). Themes associated with challenges to adherence focused on diagnosis and the physical and emotional adjustments individuals made to incorporate antiretroviral medications into their daily lives and move toward medication adherence. The factors supportive of adherence were related to the ongoing behaviors identified with establishing and maintaining adherence behaviors. What can be taken from the study is that adherence is a complex and dynamic process rather than a static behavior.

Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) infections remain a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). The adoptive transfer of donor-derived viral-specific cytotoxic T-cells (VSTs) is an effective treatment for controlling CMV and EBV infections after HSCT; however, new practical methods are required to augment the ex vivo manufacture of multi-VSTs from healthy donors. This study investigated the effects of a single exercise bout on the ex vivo manufacture of multi-VSTs. PBMCs isolated from healthy CMV/EBV seropositive participants before (PRE) and immediately after (POST) 30-minutes of cycling exercise were stimulated with CMV (pp65 and IE1) and EBV (LMP2A and BMLF1) peptides and expanded over 8 days. The number (fold difference from PRE) of T-cells specific for CMV pp65 (2.6), EBV LMP2A (2.5), and EBV BMLF1 (4.4) was greater among the VSTs expanded POST. VSTs expanded PRE and POST had similar phenotype characteristics and were equally capable of MHC-restricted killing of autologous target cells. We conclude that a single exercise bout enhances the manufacture of multi-VSTs from healthy donors without altering their phenotype or function and may serve as a simple and economical adjuvant to boost the production of multi-VSTs for allogeneic adoptive transfer immunotherapy.

2018-05-01

Mindfulness training, which teaches individuals to bring awareness and acceptance to the present moment, has been effective in improving the well-being of health care workers. Limited research examines the adoption of mindfulness practices using health behavior theories. The current study sought to conceptualize hospital health care workers' experiences in adopting mindfulness practices using the Health Belief Model (HBM), a theoretical framework used by health promotion practitioners to design and implement health behavior change interventions. Hospital health care workers in Colorado participated in an 8-week Mindfulness-Based Stress Reduction (MBSR) course. Participants ( n = 19) answered open-ended questions about their experiences adopting mindfulness practices. A theory-driven thematic analysis approach was used to analyze data with key constructs of the HBM acting as the framework for the analysis. Results showed that HBM constructs, including internal cues to action, perceived benefits and barriers, and self-efficacy, helped portray the participants' experiences and challenges in adopting and adhering to the mindfulness practices taught in the MBSR course.

Sport and recreational activities are the leading cause of injury in youth, yet there is increasing evidence that many sport-related injuries are preventable. For injury prevention strategies to be effective, individuals must understand, adopt and adhere to the recommended prevention strategy or programme. Despite the recognized importance of a behavioural approach, the inclusion of behavioural change strategies in sport injury prevention has been historically neglected. The purpose of this commentary is to outline the rationale for the inclusion and application of behavioural science in reducing the burden of injury by increasing adherence to proven prevention strategies. In an effort to provide an illustrative example of a behavioural change approach, the authors suggest a specific plan for the implementation of a neuromuscular training strategy to reduce the risk of lower limb injury in youth sport. Given the paucity of evidence in the sport injury prevention setting, and the lack of application of theoretical frameworks to predicting adoption and adherence to injury preventive exercise recommendations in youth sport, data from the related physical activity promotion domain is utilized to describe how sound, theory-based injury prevention exercise interventions in youth may be developed. While the question of how to facilitate behavioural change and optimize adherence to preventive exercise recommendations remains an ongoing challenge, the authors detail several strategies based on two prominent behavioural theories to aid the reader in conceptualizing, designing and implementing effective interventions. Despite the minimal application of behavioural theory within the field of sport injury prevention in youth, behavioural science has the potential to make a significant impact on the understanding and prevention of youth sport injury. Appropriate evaluation of adherence and maintenance components based on models of behavioural change should be a critical

The use of health information technology (HIT) may improve medication adherence, but challenges for implementation remain. The aim of this paper is to review the current state of HIT as it relates to medication adherence programs, acknowledge the potential barriers in light of current legislation, and provide recommendations to improve ongoing medication adherence strategies through the use of HIT. We describe four potential HIT barriers that may impact interoperability and subsequent medication adherence. Legislation in the United States has incentivized the use of HIT to facilitate and enhance medication adherence. The Health Information Technology for Economic and Clinical Health (HITECH) was recently adopted and establishes federal standards for the so-called "meaningful use" of certified electronic health record (EHR) technology that can directly impact medication adherence. The four persistent HIT barriers to medication adherence include (1) underdevelopment of data reciprocity across clinical, community, and home settings, limiting the capture of data necessary for clinical care; (2) inconsistent data definitions and lack of harmonization of patient-focused data standards, making existing data difficult to use for patient-centered outcomes research; (3) inability to effectively use the national drug code information from the various electronic health record and claims datasets for adherence purposes; and (4) lack of data capture for medication management interventions, such as medication management therapy (MTM) in the EHR. Potential recommendations to address these issues are discussed. To make meaningful, high quality data accessible, and subsequently improve medication adherence, these challenges will need to be addressed to fully reach the potential of HIT in impacting one of our largest public health issues.

Technical Considerations for the Generation of Adoptively Transferred T Cells in Cancer Immunotherapy

Full Text Available A significant function of the immune system is the surveillance and elimination of aberrant cells that give rise to cancer. Even when tumors are well established and metastatic, immune-mediated spontaneous regressions have been documented. While there are have been various forms of immunotherapy, one of the most widely studied for almost 40 years is adoptive cellular immunotherapy, but its success has yet to be fully realized. Adoptive cell transfer (ACT is a therapeutic modality that has intrigued physicians and researchers for its many theoretical benefits. Preclinical investigations and human trials have utilized natural killer (NK cells, dendritic cells (DC, macrophages, T-cells or B-cells for ACT with the most intense research focused on T-cell ACT. T-cells are exquisitely specific to the target of its T-cell receptor (TCR, thus potentially reducing the amount of collateral damage and off-target effects from treatment. T-cells also possess a memory subset that may reduce the risk of recurrence of a cancer after the successful treatment of the primary disease. There are several options for the source of T-cells used in the generation of cells for ACT. Perhaps the most widely known source is T-cells generated from tumor-infiltrating lymphocytes (TILs. However, studies have also employed peripheral blood mononuclear cells (PBMCs, lymph nodes, and even induced pluripotent stem cells (IPSCs as a source of T-cells. Several important technical considerations exist regarding benefits and limitations of each source of T-cells. Unique aspects of T-cells factor into their ability to be efficacious in ACT including the total number of cells available for ACT, the anti-tumor efficacy on a per cell basis, the repertoire of TCRs specific to tumor cells, and their ability to traffic to various organs that harbor tumor. Current research is attempting to unlock the full potential of these cells to effectively and safely treat cancer.

An effect of surface properties on detachment of adhered solid to cooling surface for formation of clathrate hydrate slurry

Science.gov (United States)

Daitoku, Tadafumi; Utaka, Yoshio

In air-conditioning systems, it is desirable that the liquid-solid phase change temperature of a cool energy storage material is approximately 10 °C from the perspective of improving coefficient of performance (COP). Moreover, a thermal storage material that forms slurry can realize large heat capacity of working fluids. Since the solid that adheres to the heat transfer surface forms a thermal resistance layer and remarkably reduces the rate of cold storage, it is important to avoid the adhesion of a thick solid layer on the surface so as to realize efficient energy storage. Considering a harvest type cooling unit, the force required for removing the solid phase from the heat transfer surface was studied. Tetra-n-butylammonium Bromide (TBAB) clathrate hydrate was used as a cold storage material. The effect of the heat transfer surface properties on the scraping force for detachment of adhered solid of TBAB hydrate to the heat transfer surface was examined experimentally.

Full Text Available The Mediterranean diet (MD, abundant in whole grains, is known to be one of the healthiest dietary patterns. Given the health benefits of whole grain cereals as a rich source of nutrients and phytochemicals, this study examined parental adherence to MD and its association with their adolescents’ cereals intake, in 203 parent-adolescent dyads. Adherence to MD was evaluated using the Mediterranean Diet Quality Index for adolescents (13.5±1.2y and the Short Mediterranean Diet Questionnaire for parents (41.53±5.99y. Although the level of the parents’ adherence to MD did not significantly influence the adolescents´ weekly consumption frequency of pasta and rice, adolescents whose parents had higher adherence to MD (44.3% more often ate cereals or grains for breakfast (p=0.045 and less frequently, commercially baked goods or pastries (p=0.043. Adolescents of parents who had lower adherence to MD (55.7% stated that they would eat more whole grain bakery products (p=0.049 and more breakfast cereals (p=0.039 if those foods were more often available at home. Adolescents with parents who had higher adherence to MD stated that they were more often encouraged by their parents to eat whole grain bakery products (p=0.030, compared with their counterparts whose parents had lower adherence to MD. With this study, we revealed that food environment and parental eating behaviour are notable factors that influence adolescents’ dietary intake. Disease prevention health programs should focus more strongly on encouraging parents to adopt MD features in their family food environment.

Many healthy adult cats are euthanised annually in shelters, and novel approaches are required to reduce euthanasia rates. Waiving adoption fees is one such approach. However, concerns that less responsible owners will be attracted to free events persist among welfare groups. We evaluated evidence for differences in cat fate, health, and adherence to husbandry legislation via a case-study of a free adoption-drive for cats ≥1 year at a Western Australian shelter. Post-adoption outcomes were compared between free adopters and a control group of normal-fee adopters. The free adoption-drive rehomed 137 cats, increasing average weekly adoptions by 533%. First-time adopters were a significantly larger portion of the free cohort, as a result of mixed-media promotions. Both adopter groups selected cats of similar age; sex and pelage. Post-adoption, both groups retained >90% cats, reporting near identical incidences of medical and behavioural problems. Adopters did not differ in legislative compliance regarding fitting collars, registering cats, or allowing cats to roam. The shelter reported satisfaction with the adoption-drive, because in addition to relieving crowding of healthy adults, adoption of full-fee kittens increased 381%. Overall, we found no evidence for adverse outcomes associated with free adoptions. Shelters should not be dissuaded from occasional free adoption-drives during overflow periods.

Hypertension is often treated pharmacologically, yet adherence is poor. Beliefs about antihypertensive medicine, i.e., the necessity-concern framework (NCF), are valuable for explaining adherence. Therefore, a model structure is transferred from hypercholesterolemia to hypertension, assuming a mediating role of the NCF. Patients with hypertension (n=273) were surveyed online about demographics, health- and treatment-related factors, control beliefs, necessity and concern beliefs about their medication, and adherence. The data were analyzed using structural equation modeling (SEM). Necessity was positively (β=0.26, p=0.009) and concern was negatively (β=-0.51, p=0.020) associated with adherence. The NCF mediated the influence of background variables on adherence. Necessity was associated with comorbidity (β=-0.36, pConcern was associated with side effects (β=0.38, pconcern framework as a mediating factor was confirmed in hypertension, explaining more variance than previous approaches (23%). A personalized, emotionally supportive doctor-patient communication could be key to addressing beliefs about medicine and therefore to increasing adherence. Copyright © 2017 Elsevier B.V.

Caretto, Antonio; Lagattolla, Valeria

2015-01-01

Non-communicable diseases (NCDs) also known as chronic diseases last for a long time and progress generally slow. Major non-communicable diseases are cardiovascular diseases, cancers, chronic respiratory diseases and diabetes. Unhealthy lifestyles and food behaviours play an important role for determining such diseases. The change in unhealthy behaviours or the maintenance of healthy lifestyles has enormous value in the reduction of diseases and longer life expectancy not only on an individual level but for the community as a whole. Recent meta-analyses reported Mediterranean diet to be an optimal diet when adopted as a whole, in order to preserve and maintain a good health status. A greater adherence score to the Mediterranean diet (2-point increase) was related to induce an 8% reduction in overall mortality, a 10% reduced risk of CVD and a 4% reduction in neoplastic diseases. However, there is no direct method in quantifying and evaluating adherence, therefore a large number of indirect indices in several studies have been proposed, with a last unifying score. Recently more and more e-health techniques such as web communication or desktop publishing (DVDs and so on) are being used, obtaining good results in the Mediterranean diet adherence. For successfully changing the unhealthy lifestyles and food behaviours of the population, interventions at all levels are needed with the cooperation of Institutions, mass media, agricultural and food industry and healthcare professionals guided by expert scientific societies.

Study Objectives: Obstructive sleep apnea (OSA) is a common pediatric condition characterized by recurrent partial or complete cessation of airflow during sleep, typically due to inadequate upper airway patency. Continuous positive airway pressure (CPAP) is a therapeutic option that reduces morbidity. Despite efforts to promote use, CPAP adherence is poor in both pediatric and adult populations. We sought to determine whether demographics, insurance status, OSA severity, therapeutic pressure, or comorbid conditions were associated with pediatric CPAP adherence. Methods: A retrospective review of adherence download data was performed on all pediatric patients with initiation or adjustment of CPAP treatment over a one-year period with documented in-laboratory CPAP titration. Patients were grouped as CPAP adherent or non-adherent, where adherence was defined as > 70% nightly use and average usage ≥ 4 hours per night. Differences between the groups were analyzed by χ2 test. Results: Overall, nearly half of participants were CPAP adherent (49%, 69/140). Of the demographic data collected (age, ethnicity, sex, insurance status), only female sex was associated with better adherence (60.9% vs 39.5% of males adherent; odds ratio [OR] = 2.41, 95%CI = 1.20–4.85; p = 0.01). Severity of OSA (diagnostic apnea-hypopnea index [AHI] and degree of hypoxemia), therapeutic pressure, and residual AHI did not impact CPAP adherence (p > 0.05). Patients with developmental delay (DD) were more likely to be adherent with CPAP than those without a DD diagnosis (OR = 2.55, 95%CI = 1.27–5.13; p = 0.007). Female patients with trisomy 21 tended to be more adherent, but this did not reach significance or account for the overall increased adherence associated with female sex. Conclusions: Our study demonstrates that adherence to CPAP therapy is poor but suggests that female sex and developmental delay are associated with better adherence. These findings support efforts to understand the

Full Text Available Background: Nutritional rickets is a growing global public health concern despite existing prevention programmes and health policies. We aimed to compare infant and childhood vitamin D supplementation policies, implementation strategies and practices across Europe and explore factors influencing adherence. Methods: European Society for Paediatric Endocrinology Bone and Growth Plate Working Group members and other specialists completed a questionnaire on country-specific vitamin D supplementation policy and child health care programmes, socioeconomic factors, policy implementation strategies and adherence. Factors influencing adherence were assessed using Kendall’s tau-b correlation coefficient. Results: Responses were received from 29 of 30 European countries (97%. Ninety-six per cent had national policies for infant vitamin D supplementation. Supplements are commenced on day 1–5 in 48% (14/29 of countries, day 6–21 in 48% (14/29; only the UK (1/29 starts supplements at 6 months. Duration of supplementation varied widely (6 months to lifelong in at-risk populations. Good (≥80% of infants, moderate (50–79% and low adherence (<50% to supplements was reported by 59% (17/29, 31% (9/29 and 10% (3/29 of countries, respectively. UK reported lowest adherence (5–20%. Factors significantly associated with good adherence were universal supplementation independent of feeding mode (P = 0.007, providing information at neonatal unit (NNU discharge (P = 0.02, financial family support (P = 0.005; monitoring adherence at surveillance visits (P = 0.001 and the total number of factors adopted (P < 0.001. Conclusions: Good adherence to supplementation is a multi-task operation that works best when parents are informed at birth, all babies are supplemented, and adherence monitoring is incorporated into child health surveillance visits. Implementation strategies matter for delivering efficient prevention policies.

Full Text Available Background. In TB control, poor treatment adherence is a major cause of relapse and drug resistance. Nurses have a critical role in supporting patients in TB treatment process. Yet, very little research has been done to inform policymakers and practitioners on nurses’ experiences of treatment adherence among patients with TB. Aim. To describe nurses’ experiences of supporting treatment adherence among patients with tuberculosis in Burundi. Method. The study adopted qualitative approach with a descriptive design. A purposive sampling was performed. Eight nurses were selected from two TB treatment centers in Burundi. Content analysis was used to analyze the data. Result. According to the nurses, most patients complete their treatment. Educating patients, providing the medication, observing and following up treatment, and communicating with the patients were the key tasks by nurses to support adherence. Causes for interruption were medication-related difficulties, poverty, and patients’ indiscipline. Treatment adherence could also be affected by patients’ and nurses’ feelings. Providing transportation and meals could enhance treatment compliance. Conclusion. Nurses are critical resources to TB treatment success. In a poverty stricken setting, nurses’ work could be facilitated and adherence further could be enhanced if socioeconomic problems (transportation and nutritional support were alleviated.

Participants and methods: The study was conducted in a tertiary care teaching center as part of a randomized controlled trial assessing the efficacy of an e-TOC communication tool. The e-TOC technology was developed through iterative consultation with stakeholders. This e-TOC summary was populated by acute care physicians (AcPs and communicated electronically to community care physicians (CcPs. The AcPs consisted of attending physicians, resident trainees, and medical students rotating through the Medical Teaching Unit. The CcPs were health care providers caring for patients discharged from hospital to the community. AcPs and CcPs completed validated surveys assessing their experience with the newly developed e-TOC tool. Free text questions were added to gather general comments from both groups of physicians. Units of analysis were individual physicians. Data from the surveys were analyzed using mixed methods. Results: AcPs completed 138 linked pre- and post-rotation surveys. At post-rotation, each AcP completed an average of six e-TOC summaries, taking an average of 37 minutes per e-TOC summary. Over 100 CcPs assessed the quality of the TOC summaries, with an overall rating of 8.3 (standard deviation: 1.48; on a scale of 1–10. Thematic analyses revealed barriers and opportunities encountered by physicians toward the adoption of the e-TOC tool. While the AcPs highlighted issues with timeliness, usability, and presentation, the CcPs identified barriers accessing the web-based TOC summaries, emphasizing that the summaries were timely and the

Cannabidiol (CBD) is one of the most important compounds in Cannabis sativa, lacks psychotropic effects, and possesses a high number of therapeutic properties including the amelioration of experimental autoimmune encephalomyelitis (EAE). The aim of this study was to analyse the relative efficacy of CBD in adoptively transferred EAE (at-EAE), a model that allows better delineation of the effector phase of EAE. Splenocytes and lymph nodes from mice with actively induced EAE were cultured in the presence of MOG 35-55 and IL-12 and inoculated intraperitoneally in recipient female C57BL/6J mice. The effects of CBD were evaluated using clinical scores and magnetic resonance imaging (MRI). In the central nervous system, the extent of cell infiltration, axonal damage, demyelination, microglial activation and cannabinoid receptors expression was assessed by immunohistochemistry. Lymph cell viability, apoptosis, oxidative stress and IL-6 production were measured in vitro. Preventive intraperitoneal treatment with CBD ameliorated the clinical signs of at-EAE, and this improvement was accompanied by a reduction of the apparent diffusion coefficient in the subiculum area of the brain. Inflammatory infiltration, axonal damage, and demyelination were reduced, and cannabinoid receptor expression was modulated. Incubation with CBD decreased encephalitogenic cell viability, increasing early apoptosis and reactive oxygen species (ROS) and decreasing IL-6 production. The reduction in viability was not mediated by CB 1 , CB 2 or GPR55 receptors. CBD markedly improved the clinical signs of at-EAE and reduced infiltration, demyelination and axonal damage. The CBD-mediated decrease in the viability of encephalitogenic cells involves ROS generation, apoptosis and a decrease in IL-6 production and may contribute to the therapeutic effect of this compound.

2016-06-01

Patients diagnosed with coronary heart disease are strongly recommended to adopt healthier behaviours and adhere to prescribed medication. Previous research on patients with a wide range of health conditions has explored the role of patients' illness perceptions in explaining coping and health outcomes. However, among coronary heart disease patients, this has not been well examined. The purpose of this study was to explore coronary heart disease patients' illness perception beliefs and investigate whether these beliefs could predict adherence to healthy behaviours. A multi-centre cross-sectional study was conducted at four tertiary hospitals in Jordan. A convenience sample of 254 patients (73% response rate), who visited the cardiac clinic for routine review, participated in the study. Participants completed a self-reported questionnaire, which included the Brief Illness Perception Questionnaire, the Godin Leisure Time Activity questionnaire and the Morisky Medication Adherence Scale. Patients reported high levels of disease understanding (coherence) and they were convinced that they were able to control their condition by themselves and/or with appropriate treatment. Male patients perceived lower consequences (pbehaviours. © The European Society of Cardiology 2014.

The aims of this study were to evaluate the therapeutic efficacy and to determine the immune factors for treatment success in patients with head and neck squamous cell carcinoma (HNSCC) treated with chemotherapy followed by adoptive cell transfer (ACT). A total of 43 HNSCC patients who received radical resection and chemotherapy were analysed in this study. Twenty-one of the patients were repeatedly treated with ACT after chemotherapy (ACT group), and the other twenty-two patients without ACT treatment were included as part of the control group. To investigate the immunological differences underlying these observations, we expanded and profiled improving cytokine-induced killer cells (iCIK) from peripheral blood mononuclear cells (PBMCs) with the timed addition of RetroNectin, OKT3 mAb, IFN γ and IL-2. The median of progression-free survival (PFS) and overall survival (OS) in the ACT group were significantly higher as compared to the control group (56 vs. 40; 58 vs. 45 months). In iCIK culture, there was a significant reduction in CD3+CD4+ T-cell proliferation and cytokines (IL-2, TNF) production from patients who received chemotherapy compared to patients without chemotherapy. Intra-arterial infusion of iCIK, in coordination with chemotherapy, considerably rescued iCIK culture from the suppression of systemic immunity induced by chemotherapy and induced tumour regression. Altogether, these findings suggest that ACT is an effective neo-adjuvant therapy for rescuing systemic immune suppression and improving survival time in patients with HNSCC.

Although 'best practice' guidelines for dyspepsia management have been disseminated, it remains unclear whether providers adhere to these guidelines. To compare adherence to 'best practice' guidelines among dyspepsia experts, community gastroenterologists and primary-care providers (PCPs). We administered a vignette survey to elicit knowledge and beliefs about dyspepsia including a set of 16 best practices, to three groups: (i) dyspepsia experts; (ii) community gastroenterologists and (iii) PCPs. The expert, community gastroenterologist and PCP groups endorsed 75%, 73% and 57% of best practices respectively. Gastroenterologists were more likely to adhere with guidelines than PCPs (P guideline adherence (P = 0.04). Gastroenterologists are more likely than PCPs to comply with best practices in dyspepsia, although compliance remains incomplete in both groups. PCPs harbour more concerns regarding long-term PPI use and these concerns may affect therapeutic decision making. This suggests that best practices have not been uniformly adopted and persistent guideline-practice disconnects should be addressed.

Application of Adoptive T-Cell Therapy Using Tumor Antigen-Specific T-Cell Receptor Gene Transfer for the Treatment of Human Leukemia

Full Text Available The last decade has seen great strides in the field of cancer immunotherapy, especially the treatment of melanoma. Beginning with the identification of cancer antigens, followed by the clinical application of anti-cancer peptide vaccination, it has now been proven that adoptive T-cell therapy (ACT using cancer antigen-specific T cells is the most effective option. Despite the apparent clinical efficacy of ACT, the timely preparation of a sufficient number of cancer antigen-specific T cells for each patient has been recognized as its biggest limitation. Currently, therefore, attention is being focused on ACT with engineered T cells produced using cancer antigen-specific T-cell receptor (TCR gene transfer. With regard to human leukemia, ACT using engineered T cells bearing the leukemia antigen-specific TCR gene still remains in its infancy. However, several reports have provided preclinical data on TCR gene transfer using Wilms' tumor gene product 1 (WT1, and also preclinical and clinical data on TCR gene transfer involving minor histocompatibility antigen, both of which have been suggested to provide additional clinical benefit. In this review, we examine the current status of anti-leukemia ACT with engineered T cells carrying the leukemia antigen-specific TCR gene, and discuss the existing barriers to progress in this area.

We investigate the effects of mandatory IFRS adoption on the comparability of financial accounting information. Using two comparability proxies based on De Franco et al. [2011] and a comparability proxy based on the degree of information transfer, our results suggest that the overall comparability effect of mandatory IFRS adoption is marginal. We hypothesize that firm-level heterogeneity in IFRS compliance explains the limited comparability effect. To test this conjecture, we first hand-colle...

The paper describes a study on the effects of top management support, various techno-economic factors, organizational climate, and decision-making modes on the adoption of NASA innovations. Field research consisted of interviews and questionnaires directed to sixty-five organizations. Forty-five test cases where different decisions for adoption of ideas for new products or processes were made on NASA Tech Briefs were studied in relation to the effects of various factors on the degree of success of adoption, including: (1) the degree of general connection of the technology to the firm's existing operation, (2) the specificity of the relationship between the technology and some existing and recognized problem, (3) the degree of urgency of the problem to which the technology was related, (4) maturity of technology available to implement the technology, (5) availability of personnel and financial resources to implement the technology, (6) degree of top management interest, (7) the use of confrontation in joint-decision, (8) the use of smoothing in decision-making, and (9) the use of forcing in decision-making. It was found that top managements interest was important in the product cases only, and that the success of process innovations was dependent on the quality of information and the specificity of the relationship between the technology and some recognized existing problem.

Well-designed smartphone apps can potentially help in enhancing adherence to oral anticancer medications (OAMs). The objective of this study was to evaluate patients' perception on inclusion of various adherence-enhancing strategies as features of an app and their interest in using such app. A cross-sectional survey was conducted at the National Cancer Centre Singapore. A structured self-administered questionnaire was used to collect data from patients taking OAMs. Final analysis was based on 409 surveys and most of the respondents were female (291, 71.1%), Chinese (332, 81.2%), married (296, 72.4%) and breast cancer patients (211, 51.6%). Close to two-thirds of respondents rated medication information (65.0%), disease information (60.2%) and side effect self-management (60.2%) features as having the highest level of importance in an adherence app. Three hundred thirty-two (81.2%) of the respondents owned a smartphone, among which 92 (27.7%) reported using health-related apps. From respondents with smartphones, 219 (66.0%) were interested in using an app for OAM adherence. Age 65 and older compared to 21-54 years old (adjusted OR = 0.34; 95% CI = 0.15-0.76) and current use of a health app (adjusted OR = 1.91; 95% CI = 1.07-3.41) were significant predictors of interest to adopt an adherence app. In conclusion, patients value the inclusion of educational and behavioural interventions in adherence apps. Developers of adherence apps should consider including tools for side effect self-management and provision of information to educate patients on their medications and disease condition.

The US Food and Drug Administration approved the use of sacubitril/valsartan in patients with heart failure with reduced ejection fraction in July 2015. We aimed to assess the adoption and prescription drug costs of sacubitril/valsartan in its first 18 months after Food and Drug Administration approval. Using a large US insurance database, we identified privately insured and Medicare Advantage beneficiaries who filled a first prescription for sacubitril/valsartan between July 1, 2015, and December 31, 2016. We compared them to patients treated with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker. Outcomes included adoption, prescription drug costs, and 180-day adherence, defined as a proportion of days covered ≥80%. A total of 2244 patients initiated sacubitril/valsartan. Although the number of users increased over time, the proportion of heart failure with reduced ejection fraction patients taking sacubitril/valsartan remained low (sacubitril/valsartan were younger, more often male, with less comorbidity than those taking an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. Although a majority of prescription costs were covered by the health plan (mean, $328.37; median, $362.44 per 30-day prescription), out-of-pocket costs were still high (mean, $71.16; median, $40.27). By comparison, median out-of-pocket costs were $2 to $3 for lisinopril, losartan, carvedilol, and spironolactone. Overall, 59.1% of patients were adherent to sacubitril/valsartan. Refill patterns suggested that nearly half of nonadherent patients discontinued sacubitril/valsartan within 180 days of starting. Adoption of sacubitril/valsartan after Food and Drug Administration approval has been slow and may be associated with the high cost. © 2018 American Heart Association, Inc.

To describe cardiac patients' perceptions of their responsibilities in adherence to care. The responsibilities of cardiac patients' adherence to care is a topical issue because of the increasing prevalence of noncommunicable diseases in Western countries, including cardiovascular disease (CVD). Responsibilities for cardiac patients' care have been studied, but little is described about patients' perspectives in this study. A qualitative, hermeneutic inquiry. We used face-to-face individual semistructured interviews with 21 cardiac patients (76% male) aged 58-86 in an urban area of Finland in winter 2013. The data were analysed hermeneutically with inductive content analysis. Based on our results, patients with cardiac disease understood that autonomy provided a basis for their responsibility in adherence to care. It included being able to make independent decisions, in collaboration with health professionals, or even to entrust that responsibility to healthcare professionals. Responsibilities were understood to be an expression of adherence, perceived to benefit the patient and included the duty to adopt a healthy lifestyle and care for their own medical condition. The main factors that influenced patients' responsibilities around adherence to care were their individual resources and motivation, relationships with healthcare professionals and the resources of the healthcare system. Autonomy is an inherent part of cardiac patients' adherence to care, but there has been little focus on their responsibilities in the literature. More attention needs to be paid to the healthcare providers' abilities to support patients' duties and responsibilities in clinical practice and to future research. © 2016 John Wiley & Sons Ltd.

The nature of end-stage renal disease and the need for continuous ambulatory peritoneal dialysis require patients to manage various aspects of the disease, its symptoms and treatment. After attending a training programme, patients are expected to adhere to the renal therapeutic regimen and manage their disease with the knowledge and skills learned. While patients are the stakeholders of their health and related behaviour, their perceptions of adherence and how they adhere to their renal therapeutic regimen remains unexplored. To understand adherence from patients' perspectives and to describe changes in adherence to a therapeutic regimen among patients undergoing continuous ambulatory peritoneal dialysis. This study used a mixed methods design with two phases - a survey in phase I and semi-structured interviews in phase II. This paper presents phase II of the study. The study was conducted at a renal unit of an acute hospital in Hong Kong. Based on the phase I survey results, maximum variation sampling was employed to purposively recruit 36 participants of different genders (18 males, 18 females), ages (35-76 years), and lengths of dialysis experience (11-103 months) for the phase II interviews. Data were collected by tape-recorded semi-structured interviews. Content analysis was employed to analyse the transcribed data. Data collection and analysis were conducted simultaneously. Adherence was a dynamic process with three stages. At the stage of initial adherence, participants attempted to follow instructions but found that strict persistent adherence was impossible. After the first 2-6 months of dialysis, participants entered the stage of subsequent adherence, when they adopted selective adherence through experimenting, monitoring and making continuous adjustments. The stage of long-term adherence commenced after 3-5 years of dialysis, when participants were able to assimilate the modified therapeutic regimen into everyday life. The process of adherence was

An accurate adherence index should therefore reflect treatment effectiveness, but the standard method of reporting adherence, that is, as a percentage of the agreed regimen between clinicians and people with cystic fibrosis, does not account for the appropriateness of the treatment regimen. We describe two different indices of inhaled therapy adherence for adults with cystic fibrosis which take into account effectiveness, that is, “simple” and “sophisticated” normative adherence. Methods to calculate normative adherence: Denominator adjustment involves fixing a minimum appropriate value based on the recommended therapy given a person’s characteristics. For simple normative adherence, the denominator is determined by the person’s Pseudomonas status. For sophisticated normative adherence, the denominator is determined by the person’s Pseudomonas status and history of pulmonary exacerbations over the previous year. Numerator adjustment involves capping the daily maximum inhaled therapy use at 100% so that medication overuse does not artificially inflate the adherence level. Three illustrative cases: Case A is an example of inhaled therapy under prescription based on Pseudomonas status resulting in lower simple normative adherence compared to unadjusted adherence. Case B is an example of inhaled therapy under-prescription based on previous exacerbation history resulting in lower sophisticated normative adherence compared to unadjusted adherence and simple normative adherence

Full Text Available Cooperative Extension promotes healthy behaviors, including nutritious eating and physical activity. Research-based healthy meeting guidelines pertaining to foods and beverages served at Extension-sponsored events have been adopted in some states. The extent of adherence to Healthy Eating at Meetings guidelines was assessed by observing foods and beverages served at Extension-sponsored events across one state. Over a four-month period, 69 events involving foods and/or beverages were observed, including 33 events on a state university’s campus and 46 events across 36 counties. Observed events included meetings, workshops and conferences for faculty and staff, agricultural trainings and field days for the public, 4-H camps and special activities for youth and their families, and county and state fair events. Photos and menus of the foods and beverages served were assessed using a seven-item scorecard based on the Healthy Eating at Meetings guidelines. The average score for adherence to the guidelines was 57%, with a range of 10%-93%. Results suggest that adopting healthy meeting guidelines may not be enough to ensure that nutritious foods are served and that healthy eating is modeled at Extension-sponsored events. This study indicates that further research to explore Extension professionals’ knowledge of and attitudes toward healthy meeting guidelines is needed.

Work benefits mental health in innumerable ways. Vocational rehabilitation can enhance self-esteem. Medication adherence can improve work performance and thereby the individuals' self-esteem. To test the hypothesis that there would be a significant correlation between medication adherence, work performance and self-esteem. A quantitative, descriptive correlational research design was adopted to invite patients attending psychiatric rehabilitation services to participate in the research. Data was collected from a convenience sample of 60 subjects using the 'Medication Adherence Rating scale', 'Griffiths work behaviour scale' and the 'Rosenberg's Self-esteem scale'. Analysis was done using spss18 with descriptive statistics, Pearsons correlation coefficient and multiple regression analysis. There were 36 males and 24 females who participated in this study. The subjects had good mean medication adherence of 8.4 ± 1.5 with median of 9.00, high mean self-esteem of 17.65 ± 2.97 with median of 18.0 and good mean work performance of 88.62 ± 22.56 with median of 93.0. Although weak and not significant, there was a positive correlation (r = 0.22, P = 0.103) between medication adherence and work performance; positive correlation between (r = 0.25, P = 0.067) medication adherence and self-esteem; positive correlation between (r = 0.136, P = 0.299) work performance and self-esteem. Multiple regression analysis showed no significant predictors for medication adherence, work performance and self-esteem among patients with psychiatric illness. Medication monitoring and strengthening of work habit can improve self-esteem thereby, strengthening hope of recovery from illness.

An internal image anti-idiotypic antibody, designated B1/1, was generated against an idiotope (Id91) of the monoclonal antibody (mAb91) specific for Lol pIV. The administration of B1/1 in PBS, at doses ranging from 100 ng to 100 micrograms/mouse, to syngeneic Balb/c mice resulted in the suppression of the formation of anti-Lol pIV antibodies that possessed the Id91. Spleen cells obtained from the mice 2 weeks after the treatment with B1/1 (25 micrograms/mouse) were adoptively transferred intravenously into the syngeneic recipients which were challenged intraperitoneally with Lol pIV in alum 2 hr after the transfer. The recipients were boosted with Lol pIV 14 days later. It was demonstrated that the transfer of splenic B cells (but not of T cells) from B1/1-treated donors induced a significant suppression of not only the level of IgE and IgG antibodies to Lol pIV, but also the level of antibodies possessing the Id91. Treatment of the B cells with mAb91 plus complement abrogated their ability to transfer the suppression. This study indicates that the treatment with the anti-Id B1/1 generated B cells that were characterized, serologically, as possessing the anti-Id-like antibodies on their surface and were responsible for transferring the suppression of the formation of antibodies to allergen Lol pIV and the expression of Id91.

Poor adherence to medication is a major public health challenge. Here, we aimed to determine the adherence to oral and topical medications and to analyze underlying associated factors using the translated Japanese version of Morisky Medication Adherence Scale-8 regarding urticaria treatment. Web-based questionnaires were performed for 3096 registered dermatological patients, along with a subanalysis of 751 registered urticaria patients in this study. The adherence to oral medication was significantly associated with the frequency of hospital visits. Variables that affected the adherence to topical medication included age and experience of drug effectiveness. The rate of responses that "It felt like the symptoms had improved" varied significantly among the dermatological diseases treated with oral medications. Dermatologists should be aware that adherence to the treatment of urticaria is quite low. Regular visits and active education for patients with urticaria are mandatory in order to achieve a good therapeutic outcome by increasing the adherence. © 2015 The Authors.

To conceptualize, develop, and provide preliminary psychometric evidence for the Adherence Estimator--a brief, three-item proximal screener for the likelihood of non-adherence to prescription medications (medication non-fulfillment and non-persistence) for chronic disease. Qualitative focus groups with 140 healthcare consumers and two internet-based surveys of adults with chronic disease, comprising a total of 1772 respondents, who were self-reported medication adherers, non-persisters, and non-fulfillers. Psychometric tests were performed on over 150 items assessing 14 patient beliefs and skills hypothesized to be related to medication non-adherence along a proximal-distal continuum. Psychometric tests included, but were not limited to, known-groups discriminant validity at the scale and item level. The psychometric analyses sought to identify: (1) the specific multi-item scales that best differentiated self-reported adherers from self-reported non-adherers (non-fulfillers and non-persisters) and, (2) the single best item within each prioritized multi-item scale that best differentiated self-reported adherers from self-reported non-adherers (non-fulfillers and non-persisters). The two rounds of psychometric testing identified and cross-validated three proximal drivers of self-reported adherence: perceived concerns about medications, perceived need for medications, and perceived affordability of medications. One item from each domain was selected to include in the Adherence Estimator using a synthesis of psychometric results gleaned from classical and modern psychometric test theory. By simple summation of the weights assigned to the category responses of the three items, a total score is obtained that is immediately interpretable and completely transparent. Patients can be placed into one of three segments based on the total score--low, medium, and high risk for non-adherence. Sensitivity was 88%--of the non-adherers, 88% would be accurately classified as medium

MUC1-specific cytotoxic T lymphocytes eradicate tumors when adoptively transferred in vivo.

We have reported previously that MUC1 transgenic mice with spontaneous tumors of the pancreas (designated MET) naturally develop MHC class I-restricted, MUC1-specific CTLs as tumors progress (P. Mukherjee et al., J. Immunol., 165: 3451-3460, 2000). From these MET mice, we have isolated, expanded, and cloned naturally occurring MUC1-specific CTLs in vitro. In this report, we show that the CTL line is predominantly CD8+ T cells and expresses T-cell receptor Vbeta chains 5.1/5.2, 11, 13, and 2 and Valpha chains 2, 8.3, 3.2, and 11.1/11.2. These CTLs recognize several epitopes on the MUC1 tandem repeat with highest affinity to APGSTAPPA. The CTL clone, on the other hand, is 100% CD8+ cells and expresses a single Vbeta chain of 5.1/5.2 and Valpha2. It recognizes only the H-2Db class I-restricted epitope of MUC1, APGSTAPPA. When adoptively transferred, the CTLs were effective in eradicating MUC1-expressing injected tumor cells including mammary gland cells (C57mg) and B16 melanomas. These results suggest that MUC1-specific CTLs are capable of possibly preventing, or at least substantially delaying, MUC1-expressing tumor formation. To our knowledge, this is the first evidence that demonstrates that the naturally occurring MUC1-specific CTLs isolated from one tumor model has antitumor effects on other MUC1-expressing tumors in vivo. Therefore, our data confirm that MUC1 is an important tumor rejection antigen and can serve as a target for immunotherapy.

Patient adherence with COPD therapy

Full Text Available Although there are very few published studies on adherence to treatment regimens in chronic obstructive pulmonary disease (COPD, the evidence that exists suggests that, as with asthma therapy, adherence is poor. Patient beliefs about COPD, as well as their motivation and expectations about the likelihood of success of medical interventions, can influence adherence rates. Other critical factors include the patient's understanding of their illness and therapy, and the complexity of the prescribed treatment regimen. Incorrect inhaler technique is also a common failing. When prescribing in primary or specialist care, healthcare professionals should address adherence as a vital part of the patient consultation. Improved patient education may also increase adherence rates.

Full Text Available Inflammatory bowel disease (IBD is a chronic idiopathic inflammatory condition with intestinal and extraintestinal manifestations. Medications are the cornerstone of treatment of IBD. However, patients often adhere to medication poorly. Adherence to medications is defined as the process by which patients take their medications as prescribed. Treatment non-adherence is a common problem among chronic diseases, averaging 50% in developed countries and is even poorer in developing countries. In this review, we will examine the adherence data in IBD which vary greatly depending on the study population, route of administration, and methods of adherence measurement used. We will also discuss the adverse clinical outcomes related to non-adherence to medical treatment including increased disease activity, flares, loss of response to anti-tumor necrosis factor therapy, and so forth. There are many methods to measure medication adherence namely direct and indirect methods, each with their advantages and drawbacks. Finally, we will explore different intervention strategies to improve adherence to medications.

Full Text Available AimThis paper aimed to analyze the coping strategies adopted by patients in preparation to kidney transplant, as well as associations between coping and socio-demographic data.MethodA total of 76 patients took part in this descriptive, exploratory study. While waiting for the first medical consultation regarding kidney transplantation, participants answered the Brazilian version of the Ways of Coping Scale.ResultsThe main coping strategies adopted corresponded first to religiosity, then problem focused coping and seeking for social support. There were statistically significant associations between coping categories and gender, marital status, monthly income, children’s ages, and time in dialysis.ConclusionThis study highlights the main coping strategies adopted by patients in preparation to kidney transplant, and it also reveals associations between some socio-demographic data and coping. These results may promote further psychosocial interventions, which may help to improve preparation to kidney transplants, promoting better adaptation and treatment adherence as well as fewer psychological burdens.

Rural Appalachian food deserts have disproportionately high cardiovascular disease (CVD) rates. The Mediterranean diet, consisting of plant-based dishes prepared with unsaturated fatty acids, contributes to decreased risk of CVD. Several factors can affect dietary choices in rural food deserts. The purpose of this exploratory study was to identify predisposing, reinforcing and enabling factors that affect eating a Mediterranean diet in a rural Appalachian food desert with disproportionately high rates of cardiovascular disease. The PRECEDE-PROCEED model was used as an assessment framework in this study. Volunteers (n=43) were recruited from four churches in a rural Appalachian county to participate in this mixed methods convergent parallel design study. During each of four sessions with 8-12 participants each, a Mediterranean-style meal was prepared by a local caterer and included plant-based dishes prepared with unsaturated fatty acids. The nature of a Mediterranean diet was explained to participants using an illustrated pamphlet. Nominal group process was used to determine predisposing, reinforcing and enabling factors that would affect adherence to a Mediterranean diet. Multivariate ANOVA and t-tests, using SPSS 18, were performed to determine factors associated with potential future adoption and adherence to a Mediterranean diet among a sample of rural residents and assess whether the factors varied based on age, gender and socioeconomic status. All p values of ≤0.05 were considered significant. Factors affecting future adherence to a Mediterranean diet included difficulty changing personal habits, limited access to healthy foods, cost, difficulty of preparation, limited knowledge of the health benefits of foods, family attitudes toward food and difficulty determining how to incorporate healthy foods into meals. Younger participants and those with lower incomes were more likely to identify food cost as a barrier to adherence compared to those who were older

This study reports initial results of the development of the SIAM, a non-adherence risk assessment system for tacrolimus and sirolimus for the pediatric kidney transplant population. Forty-eight youths between 10 and 25 yr of age diagnosed with chronic kidney disease or a kidney transplant used an electronic pill bottle (EM; time stamps each bottle opening) to dispense their medication for at least 30 days or until their next clinic appointment. Youth also completed a self-report adherence measure, and standard deviations were calculated for the last four medication serum trough levels obtained for each patient. Estimation models were developed for each medication (i.e., SIAM(TACRO) and SIAM(SIRO) ) to assign weights to these clinically available adherence measures (self-report and trough levels) for the calculation of a non-adherence risk composite score. SIAM(TACRO) models included both self-report and tacrolimus trough levels and significantly predicted EM. For sirolimus, the model predictive of adherence as measured by EM consisted of the standard deviation of sirolimus trough levels only (SIAM(SIRO) ). Non-adherence risk can be effectively assessed using clinically available assessment tools. However, the best methods for using self-report and trough levels to predict non-adherence likely differ based on the medication for which adherence is being assessed. © 2012 John Wiley & Sons A/S.

Evolution of adoption from Roman law to modern law

Kitanović Tanja

2013-01-01

Full Text Available The work is dedicated to the evolution of adoption practice from ancient Roman law to modern law. Adoption represents ancient social and legal practice which has during time changed manifestations and the causes it served. Adoption in ancient Rome served the interests of pater familias without biological posterity. Adoption practice benefited the continuance of families and the family cult of adopters, whose family lines, with no natural posterity, were threatened to become extinct. After the stagnation in the feudal epoch, adoption was reaffirmed in the bourgeois law. Civil codes in European countries, whose legal systems were built on the foundations of the ancient Roman legal tradition, originally favoured the interests of individuals with no biological children, who were granted to extend their families by adopting, and hence transfer their assets on the obtained heirs. After the wars in the 20th century, which led to a rapid increase in the number of parentless children, the concept of adoption was radically changed, so that since that time the adoption has primarily served the interests of the adopted children and the care for them in the adoptive families. Adoption becomes a form of a social, legal family protection of children without adequate parental care, and that is the most desirable form to provide for children, for the adoptee completely integrates with the adoptive family and takes the right of the born child, where the family environment provides and encourages the optimal mental and physical development of the child.

Adherence with Preventive Medication in Childhood Asthma

Scott Burgess

2011-01-01

Full Text Available Suboptimal adherence with preventive medication is common and often unrecognised as a cause of poor asthma control. A number of risk factors for nonadherence have emerged from well-conducted studies. Unfortunately, patient report a physician's estimation of adherence and knowledge of these risk factors may not assist in determining whether non-adherence is a significant factor. Electronic monitoring devices are likely to be more frequently used to remind patients to take medication, as a strategy to motivate patients to maintain adherence, and a tool to evaluate adherence in subjects with poor disease control. The aim of this paper is to review non-adherence with preventive medication in childhood asthma, its impact on asthma control, methods of evaluating non-adherence, risk factors for suboptimal adherence, and strategies to enhance adherence.

Clarifying the Concept of Adherence to eHealth Technology: Systematic Review on When Usage Becomes Adherence.

2017-12-06

In electronic health (eHealth) evaluations, there is increasing attention for studying the actual usage of a technology in relation to the outcomes found, often by studying the adherence to the technology. On the basis of the definition of adherence, we suggest that the following three elements are necessary to determine adherence to eHealth technology: (1) the ability to measure the usage behavior of individuals; (2) an operationalization of intended use; and (3) an empirical, theoretical, or rational justification of the intended use. However, to date, little is known on how to operationalize the intended usage of and the adherence to different types of eHealth technology. The study aimed to improve eHealth evaluations by gaining insight into when, how, and by whom the concept of adherence has been used in previous eHealth evaluations and finding a concise way to operationalize adherence to and intended use of different eHealth technologies. A systematic review of eHealth evaluations was conducted to gain insight into how the use of the technology was measured, how adherence to different types of technologies was operationalized, and if and how the intended use of the technology was justified. Differences in variables between the use of the technology and the operationalization of adherence were calculated using a chi-square test of independence. In total, 62 studies were included in this review. In 34 studies, adherence was operationalized as "the more use, the better," whereas 28 studies described a threshold for intended use of the technology as well. Out of these 28, only 6 reported a justification for the intended use. The proportion of evaluations of mental health technologies reporting a justified operationalization of intended use is lagging behind compared with evaluations of lifestyle and chronic care technologies. The results indicated that a justification of intended use does not require extra measurements to determine adherence to the technology. The

Although guidelines have recommended extended interval cervical screening using concurrent human papillomavirus (HPV) and cytology ("cotesting") for over a decade, little is known about its adoption into routine care. Using longitudinal medical record data (2003-2015) from Kaiser Permanente Northern California (KPNC), which adopted triennial cotesting in 2003, we examined adherence to extended interval screening. We analyzed predictors of screening intervals among 491,588 women undergoing routine screening, categorizing interval length into early (<2.5years), adherent (2.5<3.5years), or late (3.5<6.0years). We also examined repeated early screening in a subgroup of 50,691 women. Predictors examined included: cohort year (defined by baseline cotest, 2003-2009), race/ethnicity, and baseline age. Compared to the 2003 cohort, women in the 2009 cohort were significantly less likely to screen early (aOR=0.22, 95% CI=0.21, 0.23) or late (aOR=0.47, 95% CI=0.45, 0.49). African American (AA) and Hispanic women were less adherent overall than Non-Hispanic White women, with increased early [(AA: aOR=1.21, 95%CI=1.17, 1.25) (Hispanic: aOR=1.08, 95%CI=1.06, 1.11)] and late screening [(AA: aOR=1.23, 95%CI=1.19, 1.27) (Hispanic: aOR=1.06, 95%CI=1.03, 1.08)]. Asian women were slightly more likely to screen early (aOR=1.03, 95%CI=1.01, 1.05), and less likely to screen late (aOR=0.92, 95% CI=0.90, 0.94). Women aged 60-64years were most likely to screen early for two consecutive intervals (aOR=2.09, 95%CI=1.91, 2.29). Our study found that widespread and rapid adoption of extended interval cervical cancer screening is possible, at least in this managed care setting. Further research examining multilevel drivers promoting or restricting extended interval screening across diverse healthcare settings is needed. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background The anti-tumor efficacy of human immune effector cells, such as cytolytic T lymphocytes (CTLs, has been difficult to study in lung cancer patients in the clinical setting. Improved experimental models for the study of lung tumor-immune cell interaction as well as for evaluating the efficacy of adoptive transfer of immune effector cells are needed. Methods To address questions related to the in vivo interaction of human lung tumor cells and immune effector cells, we obtained an HLA class I + lung tumor cell line from a fresh surgical specimen, and using the infiltrating immune cells, isolated and characterized tumor antigen-specific, CD8+ CTLs. We then established a SCID mouse-human tumor xenograft model with the tumor cell line and used it to study the function of the autologous CTLs provided via adoptive transfer. Results The tumor antigen specific CTLs isolated from the tumor were found to have an activated memory phenotype and able to kill tumor cells in an antigen specific manner in vitro. Additionally, the tumor antigen-specific CTLs were fully capable of homing to and killing autologous tumors in vivo, and expressing IFN-γ, each in an antigen-dependent manner. A single injection of these CTLs was able to provide significant but temporary control of the growth of autologous tumors in vivo without the need for IL-2. The timing of injection of CTLs played an essential role in the outcome of tumor growth control. Moreover, immunohistochemical analysis of surviving tumor cells following CTL treatment indicated that the surviving tumor cells expressed reduced MHC class I antigens on their surface. Conclusion These studies confirm and extend previous studies and provide additional information regarding the characteristics of CTLs which can be found within a patient's tumor. Moreover, the in vivo model described here provides a unique window for observing events that may also occur in patients undergoing adoptive cellular

The aim of this study was to examine the association between adherence to immediate-release methylphenidate (IR MPH) and maternal psychological distress, parenting style, parent- child relationship, and perceived family support. The sample consisted of 307 children with attention-deficit hyperactivity disorder (ADHD) (271 boys and 36 girls), 6-17 years of age, who had been treated with IR MPH for the past 6 months. The measures included the Chinese Health Questionnaire, Parental Bonding Instrument, Family APGAR, and Home Behaviors of the Social Adjustment Inventory for Children and Adolescents. Reasons for poor adherence (n = 79; 25.7%) included forgetting medication (72.7%), the medication having no effect (20.0%), and refusing medication (12.7%). Increased age and three-times-daily administration were the major predictors for poor adherence to IR MPH. Poor adherence was associated with increased degree of maternal psychological distress, indifferent parenting, maternal overprotection/control, poor family support, decreased interaction with parents, and increased problems at home. Findings indicate that multiple daily dosing of MPH increases the likelihood of poor adherence, particularly in adolescents, and that poor adherence is associated with impaired maternal/family process. Once-daily administration of MPH is necessary to improve adherence and to decrease the possible exacerbation of tense parent-child relationships caused by poor drug adherence.

This study explored factors contributing to intervention adoption decisions among Emergency Medical Service (EMS) workers. Emergency Medical Service workers (n = 190), from six different organisations, participated in a two-month longitudinal study following the introduction of a patient transfer-board (also known as slide-board) designed to ease lateral transfers of patients to and from ambulance cots. Surveys administered at baseline, after one month and after two months sampled factors potentially influencing the EMS providers' decision process. 'Ergonomics Advantage' and 'Patient Advantage' entered into a stepwise regression model predicting 'intention to use' at the end of month one (R (2 )= 0.78). After the second month, the stepwise regression indicated only two factors were predictive of intention to use: 'Ergonomics Advantage,' and 'Endorsed by Champions' (R (2 )= 0.58). Actual use was predicted by: 'Ergonomics Advantage' and 'Previous Tool Experience.' These results relate to key concepts identified in the diffusion of innovation literature and have the potential to further ergonomics intervention adoption efforts. Practitioner Summary. This study explored factors that potentially facilitate the adoption of voluntarily used ergonomics interventions. EMS workers were provided with foldable transfer-boards (slideboards) designed to reduce the physical demands when laterally transferring patients. Factors predictive of adoption measures included perceived ergonomics advantage, the endorsement by champions, and prior tool experience.

To verify if there is an analogy between the indicators of the Global Reporting Initiative adopted by hospitals in the private healthcare system. Documentary research supported by reports that are electronically available on the website of the companies surveyed. The organizations surveyed had a significant adherence of their economic, social and environmental indicators of the model proposed by the Global Reporting Initiative, showing an analogous field of common indicators between them. There is similarity between the indicators adopted by companies, but one of the hospitals analyzed had a greater number of converging indicators to Global Reporting Initiative.

Stability of gene expression and transfection efficiency plays the main role in the application of gene transfer method. In somatic cell gene delivery, expression of the gene product is limited by the function of the cell to which it is delivered. In the present study analyzing the lipofected adherent cells, we have shown that lower level of transgene: beta-galactosidase activity at later time period correlated with decrease in cell viability, which was shown to be due to apoptosis. Apoptosis following DNA uptake occurred only when DNA was present during lipofection.

The purpose of this research was to examined the interactions of P. aeruginosa with hydrogel contact lenses and other substrata, and characterize adherence to lenses under various physiological and physicochemical conditions. Isolates adhered to polystyrene, glass, and hydrogel lenses. With certain lens types, radiolabeled cells showed decreased adherence with increasing water content of the lenses, however, this correlation with not found for all lenses. Adherence to rigid gas permeable lenses was markedly greater than adherence to hydrogels. Best adherence occurred near pH 7 and at a sodium chloride concentration of 50 mM. Passive adhesion of heat-killed cells to hydrogels was lower than the adherence obtained of viable cells. Adherence to hydrogels was enhanced by mucin, lactoferrin, lysozyme, IgA, bovine serum albumin, and a mixture of these macromolecules. Adherence to coated and uncoated lenses was greater with a daily-wear hydrogel when compared with an extended-wear hydrogel of similar polymer composition. Greater adherence was attributed to a higher concentration of adsorbed macromolecules on the 45% water-content lens in comparison to the 55% water-content lens

The effect of intravenously injected tumor immune spleen cells on growth of 3 X 10 5 gliosarcoma T 9 cells injected intradermally (ID) or intracerebrally (IC) into sublethally irradiated CDF rats was evaluated. Spleen cells from donor rats with sufficient immunity to reject 5 X 10 5 T 9 cells inhibited the growth of T 9 cells mixed with spleen cells in a ratio of 1:25 and injected ID, but could not act after intravenous transfer. However, donor rats which had rejected increasing T 9 challenge doses up to 1 X 10 7 cells produced immune spleen cells which, upon IV transfer, could inhibit growth of ID T 9 challenge but not of EB-679, an unrelated glioma, in recipient rats. Rejection of IC T 9 challenge was also obtained after IV transfer, in recipients of such ''hyperimmune'' spleen cells, but was less (60% maximum) than that noted after ID T 9 challenge (100% maximum). The removal of B cells from the transferred spleen cells did not affect the results, suggesting that the specific immunity was mediated by T cells. The authors conclude that the special immunological circumstances of tumors growing in the brain renders them less accessible to rejection by systemically transferred immune cells, but it is nevertheless possible to effect a significant incidence of rejection of syngeneic tumor growth in the brain by the intravenous transfer of hyperimmune spleen cells

Full Text Available Online shopping represents an innovation to be adopted or rejected by online consumersglobally. Previous experiences and knowledge of innovation are the main factors affectingpeople’s willingness to adopt a new innovation. We explore how Internet use differsbetween academicians who are innovative adopters and other types of adopters.Academicians who are innovative adopters are hypothesized to: have more years of experience on online shopping, have greater frequency of purchase, and pay a higher price for items purchased online.Data were collected from 301 respondents. Results provide new perspective on innovativeadopters among Malaysian academicians; they have less experience than other adopters inshopping for products online, make fewer purchases online and pay small amount ofmoney in shopping for products online than other adopters. Directions for future research are also discussed.

Adherence to a medical treatment means the extent to which a patient follows the instructions or recommendations by health professionals. There are direct and indirect ways to measure adherence which have been used for clinical management and research. Typically adherence measures are monitored over a long follow-up or treatment period, and some measurements may be missing due to death or other reasons. A natural question then is how to describe adherence behavior over the whole period in a simple way. In the literature, measurements over a period are usually combined just by using averages like percentages of compliant days or percentages of doses taken. In the paper we adapt an approach where patient adherence measures are seen as a stochastic process. Repeated measures are then analyzed as a Markov chain with finite number of states rather than as independent and identically distributed observations, and the transition probabilities between the states are assumed to fully describe the behavior of a patient. The patients can then be clustered or classified using their estimated transition probabilities. These natural clusters can be used to describe the adherence of the patients, to find predictors for adherence, and to predict the future events. The new approach is illustrated and shown to be useful with a simple analysis of a data set from the DART (Development of AntiRetroviral Therapy in Africa) trial in Uganda and Zimbabwe.

Full Text Available Medication adherence was assessed in 89 patients on hemodialysis (HD at the King Abdul Aziz Medical City using an Arabic version of the Morisky Medication Adherence Scale (MASS-8. The results of the study revealed that 31.46% and 40.45% of the participants showed low and medium adherence, respectively, while 28.09% showed high medication adherence. Accordingly, 71.91% of the patients visiting the dialysis unit were considered medication non-adherent. While being of older age (P = 0.012, being married (P = 0.012 increased the level of adherence, being of medium level of education (P = 0.024 decreased adherence levels. On the other hand, gender, presence of a care-giver, number of members in the household and employment status seems to have no effect on the level of medication adherence. These results call upon the practitioners in HD units to develop intervention programs that can increase the level of medication adherence.

Intestinal barrier dysfunction develops at the onset of experimental autoimmune encephalomyelitis, and can be induced by adoptive transfer of auto-reactive T cells.

Directory of Open Access Journals (Sweden)

Full Text Available Multiple sclerosis (MS is a chronic inflammatory demyelinating disease of the central nervous system with a pathogenesis involving a dysfunctional blood-brain barrier and myelin-specific, autoreactive T cells. Although the commensal microbiota seems to affect its pathogenesis, regulation of the interactions between luminal antigens and mucosal immune elements remains unclear. Herein, we investigated whether the intestinal mucosal barrier is also targeted in this disease. Experimental autoimmune encephalomyelitis (EAE, the prototypic animal model of MS, was induced either by active immunization or by adoptive transfer of autoreactive T cells isolated from these mice. We show increased intestinal permeability, overexpression of the tight junction protein zonulin and alterations in intestinal morphology (increased crypt depth and thickness of the submucosa and muscularis layers. These intestinal manifestations were seen at 7 days (i.e., preceding the onset of neurological symptoms and at 14 days (i.e., at the stage of paralysis after immunization. We also demonstrate an increased infiltration of proinflammatory Th1/Th17 cells and a reduced regulatory T cell number in the gut lamina propria, Peyer's patches and mesenteric lymph nodes. Adoptive transfer to healthy mice of encephalitogenic T cells, isolated from EAE-diseased animals, led to intestinal changes similar to those resulting from the immunization procedure. Our findings show that disruption of intestinal homeostasis is an early and immune-mediated event in EAE. We propose that this intestinal dysfunction may act to support disease progression, and thus represent a potential therapeutic target in MS. In particular, an increased understanding of the regulation of tight junctions at the blood-brain barrier and in the intestinal wall may be crucial for design of future innovative therapies.

Low ART-adherence amongst adolescents is associated with morbidity, mortality and onward HIV transmission. Reviews find no effective adolescent adherence-promoting interventions. Social protection has demonstrated benefits for adolescents, and could potentially improve ART-adherence. This study examines associations of 10 social protection provisions with adherence in a large community-based sample of HIV-positive adolescents. All 10-19-year-olds ever ART-initiated in 53 government healthcare facilities in a health district of South Africa's Eastern Cape were traced and interviewed in 2014-2015 (n = 1175 eligible). About 90% of the eligible sample was included (n = 1059). Social protection provisions were "cash/cash in kind": government cash transfers, food security, school fees/materials, school feeding, clothing; and "care": HIV support group, sports groups, choir/art groups, positive parenting and parental supervision/monitoring. Analyses used multivariate regression, interaction and marginal effects models in SPSS and STATA, controlling for socio-demographic, HIV and healthcare-related covariates. Findings showed 36% self-reported past-week ART non-adherence (75 copies/ml) (aOR 1.98, CI 1.1-3.45). Independent of covariates, three social protection provisions were associated with reduced non-adherence: food provision (aOR .57, CI .42-.76, p < .001); HIV support group attendance (aOR .60, CI .40-.91, p < .02), and high parental/caregiver supervision (aOR .56, CI .43-.73, p < .001). Combination social protection showed additive benefits. With no social protection, non-adherence was 54%, with any one protection 39-41%, with any two social protections, 27-28% and with all three social protections, 18%. These results demonstrate that social protection provisions, particularly combinations of "cash plus care", may improve adolescent adherence. Through this they have potential to improve survival and wellbeing, to prevent HIV transmission, and to advance treatment

Interest in health information exchanges (HIEs) is increasing. Several countries have adopted core health data standards with appropriate strategies. This study was conducted to determine the feasibility of a continuity of care record (CCR) as the standard for an electronic version of the official transfer note and the HIE in Korean healthcare. A technical review of the CCR standard and analysis of stakeholders' views were undertaken. Transfer notes were reviewed and matched with CCR standard categories. The standard for the Korean coding system was selected. Stakeholder analysis included an online survey of members of the Korean Society of Medical Informatics, a public hearing to derive opinions of consumers, doctors, vendors, academic societies and policy makers about the policy process, and a focus group meeting with EMR vendors to determine which HIE objects were technically applicable. Data objects in the official transfer note form matched CCR standards. Korean Classification of Diseases, Korean Standard Terminology of Medicine, Electronic Data Interchange code (EDI code), Logical Observation Identifiers Names and Codes, and Korean drug codes (KD code) were recommended as the Korean coding standard.'Social history', 'payers', and 'encounters' were mostly marked as optional or unnecessary sections, and 'allergies', 'alerts', 'medication list', 'problems/diagnoses', 'results',and 'procedures' as mandatory. Unlike the US, 'social history' was considered optional and 'advance directives' mandatory.At the public hearing there was some objection from the Korean Medical Association to the HIE on legal grounds in termsof intellectual property and patients' personal information. Other groups showed positive or neutral responses. Focus group members divided CCR data objects into three phases based onpredicted adoption time in CCR: (i) immediate adoption; (ii) short-term adoption ('alerts', 'family history'); and (iii) long-term adoption ('results', 'advanced directives

Adherence as a language game.

Kolberg, Espen Skarstein

Non-adherence, i.e. medication intake behavior not corresponding with agreed recommendations, is associated with increased morbidity and death, and it has been estimated that as many as 50% of patients in developed countries are not taking their medications as prescribed. But even as efforts in improving medication adherence over the years have increased, results are inconsistent, with only a minority of clinical trials showing any improvement in both adherence and clinical outcome. Since patient education is central to promoting good medication adherence, and language is integral to education, perhaps an exploration of the meaning and use of language, using the philosophy of Ludwig Wittgenstein, is in order.

Medicine non-adherence in kidney transplantation.

The increasing prevalence of chronic kidney disease, the relative shortage of kidney donors and the economic- and health-related costs of kidney transplant rejection make the prevention of adverse outcomes following transplantation a healthcare imperative. Although strict adherence to immunosuppressant medicine regimens is key to preventing kidney rejection, evidence suggests that adherence is sub-optimal. Strategies need to be developed to help recipients of kidney transplants adhere to their prescribed medicines. This review has found that a number of factors contribute to poor adherence, for example, attitudes towards medicine taking and forgetfulness. Few investigations have been conducted, however, on strategies to enhance medicine adherence in kidney transplant recipients. Strategies that may improve adherence include pharmacist-led interventions (incorporating counselling, medicine reviews and nephrologist liaison) and nurse-led interventions (involving collaboratively working with recipients to understand their routines and offering solutions to improve adherence). Strategies that have shown to have limited effectiveness include supplying medicines free of charge and providing feedback on a participant's medicine adherence without any educational or behavioural interventions. Transplantation is the preferred treatment option for people with end-stage kidney disease. Medicine non-adherence in kidney transplantation increases the risk of rejection, kidney loss and costly treatments. Interventions are needed to help the transplant recipient take all their medicines as prescribed to improve general well-being, medicine safety and reduce healthcare costs. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

To assess the degree of immunosuppressive medication adherence in kidney transplant patients (KTPs) and to determine if there is a difference in the rate of adherence to tacrolimus (Tac), cyclosporine (CsA) and sirolimus (Sir). From a total of 63 KTPs treated at the Clinic of Nephrology, Clinical Centre Niš, Serbia, 60 participated in the study by responding to questionnaires. They were divided into the adherence group (n = 43) and the nonadherence group (n = 17) according to their degree of adherence which was measured using a validated survey form, the simplified medication adherence questionnaire. The KTP adherence to the different immunosuppressive regimens (Tac, CsA and Sir) was compared. Statistical analysis was performed using the Student t test. Adherence was observed in 43 (71.7%) patients, and only 17 (28.3%) did not follow the prescribed therapy. The estimated glomerular filtration rate was significantly lower in the nonadherence group (38.52 ± 18.22 ml/min) than in the adherence group (52.43 ± 16.91 ml/min, p adherers and the nonadherers (6.30 ± 2.06 vs. 5.0 ± 1.52 ng/ml, p adherence. Nonadherence was associated with worse graft function and a lower Tac level.

Purpose While interpretative phenomenological analysis (IPA) has been used in health psychology research, it has so far not been applied to seek deeper insights into the patients' experiences about treatment. The purpose of this paper is to address this gap by using IPA to understand patient non-adherence. Design/methodology/approach In total, 18 patients with chronic conditions seeking healthcare services in Goa and Karnataka, India, were selected by using the snowball sampling method. In-depth interviews were conducted face to face. A semi-structured questionnaire developed by the researchers was used to collect the data. IPA was used to explore the themes to predict patient non-adherence. Findings The study results indicate that economic factors, health system related factors, social factors and psychological factors impact patient non-adherence. Patient non-adherence includes medication non-adherence and lifestyle modification non-adherence. Research limitations/implications Being cross sectional in design, the results may not be as appropriate as the results derived from a longitudinal study given that non-adherence occurs over time. Practical implications Patient non-adherence is a global health issue. Multidisciplinary approach to enhance patient adherence to treatment should form part of public healthcare policy. Social implications Exploring the factors influencing patient non-adherence will help the health-care industry stakeholders to reduce healthcare cost and improve patient's quality of life. Originality/value Although there is extensive quantitative research on the prevalence of non-adherence, qualitative research is limited. This paper addresses this gap by using IPA to understand patient non-adherence and its factors and dimensions.

Mechanisms of immunological eradication of a syngeneic guinea pig tumor: participation of a component(s) of recipient origin in the expression of systemic adoptive immunity

The effects of carrageenan and trypan blue on the expression of adoptive immunity to the syngeneic guinea pig line 10 hepatoma were investigated. Adoptive immunity was assessed by observing dermal tumor growth in recipients of immune cells and by bioassays in which tumor challenge sites were transplanted into secondary hosts. Carrageenan abrogated transferred immunity in treated animals as evidenced by dermal tumor growth and by development of fatal ascites tumors in peritoneal cavities of the secondary hosts. Trypan blue, on the other hand, did not abrogate transferred immunity in treated animals. However, the i.p. bioassay revealed the presence of line 10 cells in the tumor challenge sites 10 days after adoptive transfer. In vitro and in vivo exposure of immune spleen cells to carrageenan or trypan blue had no significant effect on the subsequent adoptive transfer, indicating that the inhibitory activity of these agents cannot be attributed to direct toxicity to immune lymphoid cells. Tumor challenge sites taken from carrageenan or trypan blue-treated animals 5 days after adoptive transfer failed to grow progressively when transplanted s.c. into secondary hosts. This observation suggests the presence of immune cells at tumor challenge sites. Thus, the inhibitory effects were unlikely due to interference with recirculation of the i.v.-transferred immune cells. Adoptive immunity was not influenced in guinea pigs that received a lethal dose of irradiation (500 rads). These results demonstrate that a recipient component(s) sensitive to carrageenan and trypan blue but resistant to radiation is essential to the expression of adoptive immunity

To understand decision making concerning adoption and nonadoption of accelerated partial breast radiotherapy (RT) prior to long-term randomized trial evidence. A total of 36 radiation oncologists and surgeons were recruited through purposive and snowball sampling strategies from September 2010 through January 2013. Semistructured phone interviews were conducted and audio-recorded and lasted 20-45 minutes. Qualitative analysis was conducted using a framework approach, iteratively exploring key concepts and emerging issues raised by subjects. Interviews were transcribed and imported into Atlas.ti v6. Transcripts were independently coded by 3 researchers shortly after each interview, followed by consensus development on each coded transcript. Barriers and facilitators of adoption, practice patterns, and informational/educational sources concerning accelerated partial breast RT were all assessed to determine major themes. Nearly half of physicians were surgeons (47%), and half were radiation oncologists (53%), with 61% overall in urban settings. Twenty-nine of the 36 physicians interviewed used brachytherapy-based partial breast RT. Five major factors were involved in physicians' decisions to adopt accelerated partial breast RT: facilitators encouraging adoption (e.g., enthusiastic colleagues and patient convenience), financial and prestige incentives, pressures to adopt (e.g., potential declines in referrals), judgment concerning acceptable level of scientific evidence, and barriers (e.g., not having appropriate machinery or referral mechanism in place). If technology was adopted, clinical guideline adherence varied. Technology adoption is based on financial and social pressures, along with often-limited scientific evidence and what seems "best" for patients. For technology adoption and diffusion to be rational and evidence-based, we must encourage appropriate financial payment models to curb use outside of research studies and promote development of additional

Psychotropic medications are commonly used for depressive symptoms among people living with HIV/AIDS. We examined the relationships between adherence to psychotropic medications, depressive symptoms, and antiretroviral adherence. We assessed depressive symptoms among 324 people living with HIV/AIDS across a 3-month period (70% men; mean age 45 years; 90% African-American). Psychotropic and antiretroviral adherence was assessed using monthly, unannounced telephone pill counts. Multiple-regression and mediation analyses were utilized to examine associations under investigation. Greater depressive symptoms were associated with lower antiretroviral and psychotropic medication adherence. Greater adherence to psychotropic medications regardless of medication class was positively related to higher antiretroviral adherence. Greater adherence to psychotropic medications also significantly mediated the association between depressive symptoms and antiretroviral adherence. This study demonstrates the benefits of adherence to psychotropic medications on both depressive symptoms and antiretroviral adherence. Future work examining psychotropic medication adherence on disease outcomes in people living with HIV/AIDS is warranted.

Unlike in the past, most adoption agencies today offer birth parents and adoptive parents the opportunity to share identifying information and have contact with each other. To understand the impacts of different open adoption arrangements, a qualitative descriptive study using a snowball sample of 44 adoptive parents throughout New England began in 1988. Every seven years these parents who adopted infants in open adoptions have participated in tape-recorded interviews to explore their evolving reactions to their open adoption experiences. This article reports the results of in-depth interviews with these parents now that their children have reached young adulthood. This longitudinal research illuminates how open adoptions change over the course of childhood and adolescence, parents' feelings about open adoption, challenges that emerge in their relationships with their children's birth families, how those challenges are managed and viewed, and parents' advice for others living with open adoption and for clinical social work practice and policy. Findings reveal that regardless of the type of openness, these adoptive parents generally feel positive about knowing the birth parents and having contact with them, are comfortable with open adoption, and see it serving the child's best interests.

Washing and changing uniforms: is guidance being adhered to?

Potter, Yvonne Camilla; Justham, David

To allay public apprehension regarding the risk of nurses' uniforms transmitting healthcare-associated infections (HCAI), national and local guidelines have been issued to control use, laundry and storage. This paper aims to measure the knowledge of registered nurses (RNs) and healthcare assistants (HCAs) working within a rural NHS foundation Trust and their adherence to the local infection prevention and control (IPC) standard regarding uniforms through a Trust-wide audit. Stratified random sampling selected 597 nursing staff and 399 responded (67%) by completing a short questionnaire based on the local standard. Responses were coded and transferred to SPSS (v. 17) for analysis. The audit found that nursing staff generally adhere to the guidelines, changing their uniforms daily and immediately upon accidental soiling, and wearing plastic aprons where indicated. At home, staff normally machine-wash and then iron their uniforms at the hottest setting. Nevertheless, few observe the local direction to place their newly-laundered uniforms in protective covers. This paper recommends a re-audit to compare compliance rates with baseline figures and further research into the reasons why compliance is lacking to sanction interventions for improvement, such as providing relevant staff education and re-introducing appropriate changing facilities.

Full Text Available Introduction: In the general population, medication nonadherence contributes to poorer outcomes. However, little is known about medication adherence among adults with chronic kidney disease (CKD. We evaluated the association of self-reported medication adherence with CKD progression and all-cause death in patients with CKD. Methods: In this prospective observational study of 3305 adults with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC Study, the baseline self-reported medication adherence was assessed by responses to 3 questions and categorized as high, medium, and low. CKD progression (50% decline in eGFR or incident end-stage renal disease and all-cause death were measured using multivariable Cox proportional hazards. Results: Of the patients, 68% were categorized as high adherence, 17% medium adherence, and 15% low adherence. Over a median follow-up of 6 years, there were 969 CKD progression events and 675 deaths. Compared with the high-adherence group, the low-adherence group experienced increased risk for CKD progression (hazard ratio = 1.27, 95% confidence interval = 1.05, 1.54 after adjustment for sociodemographic and clinical factors, cardiovascular medications, number of medication types, and depressive symptoms. A similar association existed between low adherence and all-cause death, but did not reach standard statistical significance (hazard ratio = 1.14 95% confidence interval = 0.88, 1.47. Conclusion: Baseline self-reported low medication adherence was associated with an increased risk for CKD progression. Future work is needed to better understand the mechanisms underlying this association and to develop interventions to improve adherence. Keywords: CKD, death, medication adherence, progression

Continuous positive airway pressure (CPAP) is a highly efficacious treatment for obstructive sleep apnea (OSA) but adherence to the treatment limits its overall effectiveness across all age groups of patients. Factors that influence adherence to CPAP include disease and patient characteristics, treatment titration procedures, technological device factors and side effects, and psychological and social factors. These influential factors have guided the development of interventions to promote CPAP adherence. Various intervention strategies have been described and include educational, technological, psychosocial, pharmacological, and multi-dimensional approaches. Though evidence to date has led to innovative strategies that address adherence in CPAP-treated children, adults, and older adults, significant opportunities exist to develop and test interventions that are clinically applicable, specific to subgroups of patients likely to demonstrate poor adherence, and address the multifactorial nature of CPAP adherence. The translation of CPAP adherence promotion interventions to clinical practice is imperative to improve health and functional outcomes in all persons with CPAP-treated OSA. PMID:21652236

While communicable diseases are the leading causes of morbidity and mortality in Malawi, the contribution of nosocomial or hospital-acquired infections (HAIs) is unknown but could be substantial. The single most important method of preventing nosocomial infections is hand hygiene. We report a study which was conducted in 2011 to investigate adherence to hand hygiene protocols by clinicians and medical students working at Queen Elizabeth Central Hospital in Blantyre, Malawi. There were two parts to the study: a single blinded arm in which participants were observed without their knowledge by trained nurses; and a second arm which included self-completion of questionnaire after participant consent was obtained. The 2009 World Health Organization hand hygiene technique and recommendations which were adopted by Queen Elizabeth Central Hospital were used to define an opportunity for hand washing and effectiveness of hand washing. Hand hygiene effectiveness was defined as adherence to at least 6 out of 7 steps (80%) of the hand hygiene technique when using alcohol-based formulation or at least 8 out of 10 steps (80%) of the hand hygiene technique when using water and soap formulation before and after having direct contact with patients or their immediate surroundings. Clinicians were found to have disinfected their hands more than medical students (phand sanitizer and hand hygiene practice (p=0.3). Adherence to hand hygiene was found to be 23%. Most of the participants mentioned infection transmission prevention as a reason for disinfecting their hands. Other reasons mentioned included: a routine personal hand hygiene behaviour and discomfort if not washing hands. The top three reasons why they did not disinfect hands were forgetfulness, unavailability of sanitizers and negligence. Adherence to hand hygiene practice was found to be low, with forgetfulness and negligence being the major contributing factors. A hospital-wide multifaceted program aiming at clinicians and

Vitamin supplementation in bariatric aftercare is essential to prevent nutrient deficiencies; however, rates of vitamin adherence have been as low as 30 % 6 months post-surgery. Preliminary literature suggests non-adherence to prescribed treatments can be linked to demographic and psychological factors. We aimed to determine the relationship between these factors to vitamin adherence in post-bariatric surgery patients. A total of 92 bariatric patients were assessed 6 months post-surgery. Patients were administered a questionnaire collecting demographic information, psychological scores, and self-reported adherence. Nutrient deficiencies were analyzed through serum vitamin levels measured 3 and 6 months after surgery. Wilcoxon rank-sum and chi-square tests were used for analysis. Non-adherence was associated with male sex and full-time employment (p = 0.027, p = 0.015). There were no differences with respect to living situation, education level, or relationship type. Non-adherent patients did not have significantly higher scores for generalized anxiety, depressive symptoms, or avoidant behaviors. However, non-adherent patients displayed greater attachment anxiety than their adherent counterparts (p = 0.0186). Non-adherence was also associated with lower vitamin B12 levels 6 months post-surgery (p = 0.001). Male gender and full-time work have previously been shown to be associated with non-adherence. This is the first study to demonstrate that attachment anxiety is associated with poor multivitamin adherence in the post-surgical bariatric population. This result is concordant with recent literature that has demonstrated attachment anxiety is associated with poor adherence to dietary recommendations in bariatric patients 6 months postoperatively. Presurgical screening for attachment anxiety could facilitate early interventions to promote better bariatric aftercare in this group.

Current Situation of Medication Adherence in Hypertension.

2017-01-01

Despite increased awareness, poor adherence to treatments for chronic diseases remains a global problem. Adherence issues are common in patients taking antihypertensive therapy and associated with increased risks of coronary and cerebrovascular events. Whilst there has been a gradual trend toward improved control of hypertension, the number of patients with blood pressure values above goal has remained constant. This has both personal and economic consequences. Medication adherence is a multifaceted issue and consists of three components: initiation, implementation, and persistence. A combination of methods is recommended to measure adherence, with electronic monitoring and drug measurement being the most accurate. Pill burden, resulting from free combinations of blood pressure lowering treatments, makes the daily routine of medication taking complex, which can be a barrier to optimal adherence. Single-pill fixed-dose combinations simplify the habit of medication taking and improve medication adherence. Re-packing of medication is also being utilized as a method of improving adherence. This paper presents the outcomes of discussions by a European group of experts on the current situation of medication adherence in hypertension.

Adoptive parenting.

Challenges in adoptive parenting continue to emerge as adoption policies and practices evolve. We review three areas of research in adoptive parenting that reflect contemporary shifts in adoption. First, we highlight recent findings concerning openness in adoption contact arrangements, or contact between a child's families of birth and rearing. Second, we examine research regarding racial and cultural socialization in transracial and international adoptions. Finally, we review investigations of parenting experiences of lesbian and gay adoptive parents. Overall, parenting processes (e.g., supportive vs. problematic family interaction) are better predictors of child adjustment than are group differences (e.g., open vs. closed adoptions; adoption by heterosexual vs. same-sex parents). The distinctive needs of adopted children call for preparation of adoption-competent mental health, casework, education, and health care professionals. Copyright © 2017 Elsevier Ltd.

Miller, R L

2001-08-01

A multiple case study design was used to explore the organizational characteristics of community-based organizations that provide HIV prevention programs and the criteria these organizations employ when judging the merits of externally-developed HIV prevention programs. In-depth interviews were conducted with organizational representatives of 38 randomly-selected HIV prevention providers throughout Illinois. Results indicated that there were three main types of adopting organizations: adopters of entire programs, adopters of program components and practices, and adopters of common ideas. These three types of organizations were distinguished by their level of organizational commitment to HIV prevention, organizational resources, and level of organizational maturity. Narrative data from the interviews are used to describe the dimensions that underlie the organizations' program adoption criteria. The criteria of merit used by these organizations to evaluate prevention programs provide partial empirical support for existing theories of technology transfer. Implications for designing and disseminating HIV prevention programs are discussed.

A mental model is the collection of an individual's perceptions, values, and expectations about a particular aspect of their life, which strongly influences behaviors. This study explored orthopedic outpatients mental models of adherence to prescribed home exercise programs and how they related to mental models of adherence to other types of personal regimens. The study followed an interpretive description qualitative design. Data were collected via two semi-structured interviews. Interview One focused on participants prior experiences adhering to personal regimens. Interview Two focused on experiences adhering to their current prescribed home exercise program. Data analysis followed a constant comparative method. Findings revealed similarity in perceptions, values, and expectations that informed individuals mental models of adherence to personal regimens and prescribed home exercise programs. Perceived realized results, expected results, perceived social supports, and value of convenience characterized mental models of adherence. Parallels between mental models of adherence for prescribed home exercise and other personal regimens suggest that patients adherence behavior to prescribed routines may be influenced by adherence experiences in other aspects of their lives. By gaining insight into patients adherence experiences, values, and expectations across life domains, clinicians may tailor supports that enhance home exercise adherence. Implications for Rehabilitation A mental model is the collection of an individual's perceptions, values, and expectations about a particular aspect of their life, which is based on prior experiences and strongly influences behaviors. This study demonstrated similarity in orthopedic outpatients mental models of adherence to prescribed home exercise programs and adherence to personal regimens in other aspects of their lives.

Improving adherence to antiretroviral therapy

Full Text Available Antiretroviral therapy (ART has transformed HIV infection into a treatable, chronic condition. However, the need to continue treatment for decades rather than years, calls for a long-term perspective of ART. Adherence to the regimen is essential for successful treatment and sustained viral control. Studies have indicated that at least 95% adherence to ART regimens is optimal. It has been demonstrated that a 10% higher level of adherence results in a 21% reduction in disease progression. The various factors affecting success of ART are social aspects like motivation to begin therapy, ability to adhere to therapy, lifestyle pattern, financial support, family support, pros and cons of starting therapy and pharmacological aspects like tolerability of the regimen, availability of the drugs. Also, the regimen′s pill burden, dosing frequency, food requirements, convenience, toxicity and drug interaction profile compared with other regimens are to be considered before starting ART. The lack of trust between clinician and patient, active drug and alcohol use, active mental illness (e.g. depression, lack of patient education and inability of patients to identify their medications, lack of reliable access to primary medical care or medication are considered to be predictors of inadequate adherence. Interventions at various levels, viz. patient level, medication level, healthcare level and community level, boost adherence and overall outcome of ART.

Treatment adherence in hemodialysis is important for guaranteeing better results for patients, but Brazil still lacks validated assessment tools for this purpose. The current study aimed to perform a cross-cultural adaptation of the Renal Adherence Behaviour Questionnaire (RABQ) and the Renal Adherence Attitudes Questionnaire (RAAQ). The two questionnaires were submitted to the following cross-cultural adaptation procedures: translation, back-translation, expert panel review, and pilot study. Changes were made in the items' wording and application, which requires a face-to-face interview. It was not necessary to change the choices of answers. The Brazilian versions of the RABQ and RAAQ showed semantic and cultural equivalence to the original versions and are easy for the target population to understand. The two scales still require validity and reliability studies before use in the field.

Adoption research, practice, and societal trends: Ten years of progress.

Adoption involves the legal transfer of parental rights and responsibilities from a child's birth parents to adults who will raise the child (Reitz & Watson, 1992). Research related to adoption has expanded over the past 10 years and has incorporated more focus on implications for practice and public policy. This expansion has reflected increased awareness of the lived experience of adopted individuals, in addition to that of adoptive families and birth or first parents and families, collectively known as the adoption kinship network (Grotevant & McRoy, 1998). Trends discussed included research and social trends or movements (2007-2017) since the publication of the final article in a series of articles in the psychological literature related to adoption in The Counseling Psychologist (Baden & Wiley, 2007; Lee, 2003; O'Brien & Zamostny, 2003; Wiley & Baden, 2005; Zamostny, O'Brien, Baden, & Wiley, 2003; Zamostny, Wiley, O'Brien, Lee, & Baden, 2003). This article summarizes the social trends and research related to adoption over the last 10 years, including longitudinal and meta-analytic studies, increased research and conceptualization of ethnic and racial identity development, research on microaggressions, and research on diverse adoptive families, including those with gay and lesbian parents. Social trends included increased knowledge related to Internet accessibility, genetic information, continued focus on openness, and viewing adoption through a more critical lens. Implications are discussed for the development of programs that enhance competence of mental health professionals and adoption professionals in adoption-competent practice.

2012-08-01

Full Text Available Abstract Background The extent to which patients follow treatments as prescribed is pivotal to treatment success. An exceptionally high level (> 95% of HIV medication adherence is required to suppress viral replication and protect the immune system and a similarly high level (> 80% of adherence has also been suggested in order to benefit from prescribed exercise programmes. However, in clinical practice, adherence to both often falls below the desirable level. This project aims to investigate a wide range of psychological and personality factors that may lead to adherence/non-adherence to medical treatment and exercise programmes. Methods HIV positive patients who are referred to the physiotherapist-led 10-week exercise programme as part of the standard care are continuously recruited. Data on social cognitive variables (attitude, intention, subjective norms, self-efficacy, and outcome beliefs about the goal and specific behaviours, selected personality factors, perceived quality of life, physical activity, self-reported adherence and physical assessment are collected at baseline, at the end of the exercise programme and again 3 months later. The project incorporates objective measures of both exercise (attendance log and improvement in physical measures such as improved fitness level, weight loss, improved circumferential anthropometric measures and medication adherence (verified by non-invasive hair analysis. Discussion The novelty of this project comes from two key aspects, complemented with objective information on exercise and medication adherence. The project assesses beliefs about both the underlying goal such as following prescribed treatment; and about the specific behaviours such as undertaking the exercise or taking the medication, using both implicit and explicit assessments of patients’ beliefs and attitudes. We predict that i the way people think about the underlying goal of their treatments explains medication and exercise

Suppressor cells in transplantation tolerance. I. Analysis of the suppressor status of neonatally and adoptively tolerized rats

Dorsch, S.; Roser, B.

The lymphocytes from neonatally tolerant rats which adoptively transfer tolerance to sublethally irradiated recipients do so by specifically suppressing the regeneration of alloreactivity which normally occurs after irradiation. Although tolerant cells will only partially suppress normal alloreactive cells when the two are mixed in near equivalent numbers, experiments in which the interval between injection of tolerant and normal cells into irradiated recipients was gradually extended, indicated that total suppression of normally alloreactive cells was achieved after 8 weeks of prior residence of tolerant cells in the adoptive host. Further evidence that tolerant cells would only suppress if present in excess of normal cells was obtained by reducing the tolerant cell population in tolerant donor rats by whole body irradiation. These animals then lost their ability to suppress normal alloreactive cells administered to them. The immune status of adoptively tolerized animals did not mimic that of the donors of the tolerant cells. Even where full tolerance, as measured by skin graft survival, failure to synthesize alloantibodies, and capacity to further transfer skin graft tolerance to secondary recipients, was evident the lymphocytes of these animals showed considerable graft-versus-host (GVH) reactivity. The persistence of tolerance through repeated adoptive transfers was correlated with the persistence of donor (chimeric) cells and the indicator skin graft on adoptive recipients only amplified tolerance expression where the inocula of tolerant cells given was weakly suppressive. Finally, removal of the minor population of chimeric cells from tolerant inocula using cytotoxic alloantisera abolished the capacity to transfer tolerance. These results imply an active role for chimeric cells which is best understood as an immune response involving proliferation driven by the idiotypes of the alloreceptors on host cells

Low adherence in recent HIV prevention clinical trials highlights the need to better understand, measure, and support product use within clinical trials. Conventional self-reported adherence instruments within HIV prevention trials, often relying on single-item questions, have proven ineffective. While objective adherence measures are desirable, none currently exist that apply to both active and placebo arms. Scales are composed of multiple items in the form of questions or statements that, when combined, measure a more complex construct that may not be directly observable. When psychometrically validated, such measures may better assess the multiple factors contributing to adherence/non-adherence. This study aimed to develop and psychometrically evaluate tools to screen and monitor trial participants' adherence to HIV prevention products within the context of clinical trial research. Based on an extensive literature review and conceptual framework, we identified and refined 86 items assessing potential predictors of adherence and 48 items assessing adherence experience. A structured survey, including adherence items and other variables, was administered to former ASPIRE and Ring Study participants and similar non-trial participants (n = 709). We conducted exploratory factor analyses (EFA) to identify a reduced set of constructs and items that could be used at screening to predict potential adherence, and at follow-up to monitor and intervene on adherence. We examined associations with other variables to assess content and construct validity. The EFA of screener items resulted in a 6-factor solution with acceptable to very good internal reliability (α: .62-.84). Similar to our conceptual framework, factors represent trial-related commitment (Distrust of Research and Commitment to Research); alignment with trial requirements (Visit Adherence and Trial Incompatibility); Belief in Trial Benefits and Partner Disclosure. The EFA on monitoring items resulted in 4

Sharia Adherence Mosque Survey: Correlations between Sharia Adherence and Violent Dogma in U.S. Mosques

Full Text Available A random survey of 100 representative mosques in the U.S. was conducted to measure the correlation between Sharia adherence and dogma calling for violence against non-believers.  Of the 100 mosques surveyed, 51% had texts on site rated as severely advocating violence; 30% had texts rated as moderately advocating violence; and 19% had no violent texts at all.  Mosques that presented as Sharia adherent were more likely to feature violence-positive texts on site than were their non-Sharia-adherent counterparts.  In 84.5% of the mosques, the imam recommended studying violence-positive texts.  The leadership at Sharia-adherent mosques was more likely to recommend that a worshipper study violence-positive texts than leadership at non-Sharia-adherent mosques.  Fifty-eight percent of the mosques invited guest imams known to promote violent jihad.  The leadership of mosques that featured violence-positive literature was more likely to invite guest imams who were known to promote violent jihad than was the leadership of mosques that did not feature violence-positive literature on mosque premises.  

Can human error theory explain non-adherence?

Barber, Nick; Safdar, A; Franklin, Bryoney D

2005-08-01

To apply human error theory to explain non-adherence and examine how well it fits. Patients who were taking chronic medication were telephoned and asked whether they had been adhering to their medicine, and if not the reasons were explored and analysed according to a human error theory. Of 105 patients, 87 were contacted by telephone and they took part in the study. Forty-two recalled being non-adherent, 17 of them in the last 7 days; 11 of the 42 were intentionally non-adherent. The errors could be described by human error theory, and it explained unintentional non-adherence well, however, the application of 'rules' was difficult when considering mistakes. The consideration of error producing conditions and latent failures also revealed useful contributing factors. Human error theory offers a new and valuable way of understanding non-adherence, and could inform interventions. However, the theory needs further development to explain intentional non-adherence.

Potential facilitators and barriers to adopting standard treatment guidelines in clinical practice.

2017-04-18

Purpose The purpose of this paper is to assess medicines information sources accessed by clinicians, if sources differed in theory and practice and to find out the barriers and facilitators to effective guideline adoption. Design/methodology/approach In all, 183 doctors were surveyed. Barriers and facilitators were classified as: communication; potential adopters; innovation; organization characteristics and environmental/social/economic context. Findings Most of the clinicians accessed multiple information sources including standard treatment guidelines, but also consulted seniors/colleagues in practice. The top three factors influencing clinical practice guideline adoption were innovation characteristics, environmental context and individual characteristics. The respondents differed in the following areas: concerns about flexibility offered by the guideline; denying patients' individuality; professional autonomy; insights into gaps in current practice and evidence-based practice; changing practices with little or no benefit. Barriers included negative staff attitudes/beliefs, guideline integration into organizational structures/processes, time/resource constraints. Fearing third parties (government and insurance companies) restricting medicines reimbursement and poor liability protection offered by the guidelines emerged as the barriers. Facilitators include aligning organizational structures/processes with the innovation; providing leadership support to guide diffusion; increasing awareness and enabling early innovation during pre/in-service training, with regular feedback on outcomes and use. Practical implications Guideline adoption in clinical practice is partly within doctors' control. There are other key prevailing factors in the local context such as environmental, social context, professional and organizational culture affecting its adoption. Organizational policy and accreditation standards necessitating adherence can serve as a driver. Originality

The purpose of this investigation was to examine treatment adherence to medication and lifestyle recommendations among pediatric migraine patients using electronic monitoring systems. Nonadherence to medical treatment is a significant public health concern, and can result in poorer treatment outcomes, decreased cost-effectiveness of medical care, and increased morbidity. No studies have systematically examined adherence to medication and lifestyle recommendations in adolescents with migraine outside of a clinical trial. Participants included 56 adolescents ages 11-17 who were presenting for clinical care. All were diagnosed with migraine with or without aura or chronic migraine and had at least 4 headache days per month. Medication adherence was objectively measured using electronic monitoring systems (Medication Event Monitoring Systems technology) and daily, prospective self-report via personal electronic devices. Adherence to lifestyle recommendations of regular exercise, eating, and fluid intake were also assessed using daily self-report on personal electronic devices. Electronic monitoring indicates that adolescents adhere to their medication 75% of the time, which was significantly higher than self-reported rates of medication adherence (64%). Use of electronic monitoring of medication detected rates of adherence that were significantly higher for participants taking once daily medication (85%) versus participants taking twice daily medication (59%). Average reported adherence to lifestyle recommendations of consistent noncaffeinated fluid intake (M = 5 cups per day) was below recommended levels of a minimum of 8 cups per day. Participants on average also reported skipping 1 meal per week despite recommendations of consistently eating three meals per day. Results suggest that intervention focused on adherence to preventive treatments (such as medication) and lifestyle recommendations may provide more optimal outcomes for children and adolescents with

2014-01-01

The expansion of cancer-induced myeloid cells is thought to be one of the main obstacles to successful immunotherapy. Nevertheless, in murine tumors undergoing immune-mediated destruction by adoptively transferred T cells, we have recently shown that such cells maintain their immunosuppressive properties. Therefore, adoptive T-cell therapy can, under certain conditions, overcome myeloid cell immunosuppression. PMID:25050213

Although evidence shows that poor air quality can harm human health, we have a limited understanding about the behavioural impact of air quality forecasts. Our aim was to understand to what extent air quality warning systems influence protective behaviours in the general public, and to identify the demographic and psychosocial factors associated with adherence and non-adherence to the health advice accompanying these warnings. In August 2016 literature was systematically reviewed to find studies assessing intended or actual adherence to health advice accompanying air quality warning systems, and encouraging people to reduce exposure to air pollution. Predictors of adherence to the health advice and/or self-reported reasons for adherence or non-adherence were also systematically reviewed. Studies were included only if they involved participants who were using or were aware of these warning systems. Studies investigating only protective behaviours due to subjective perception of bad air quality alone were excluded. The results were narratively synthesised and discussed within the COM-B theoretical framework. Twenty-one studies were included in the review: seventeen investigated actual adherence; three investigated intended adherence; one assessed both. Actual adherence to the advice to reduce or reschedule outdoor activities during poor air quality episodes ranged from 9.7% to 57% (Median = 31%), whereas adherence to a wider range of protective behaviours (e.g. avoiding busy roads, taking preventative medication) ranged from 17.7% to 98.1% (Median = 46%). Demographic factors did not consistently predict adherence. However, several psychosocial facilitators of adherence were identified. These include knowledge on where to check air quality indices, beliefs that one's symptoms were due to air pollution, perceived severity of air pollution, and receiving advice from health care professionals. Barriers to adherence included: lack of understanding of the indices

Olstad, Dana Lee; Raine, Kim D; McCargar, Linda J

Little is known about how public entities can partner with industry to achieve public health goals. We investigated industry's perspective of factors that influenced their adoption and implementation of voluntary, government-issued nutrition guidelines (Alberta Nutrition Guidelines for Children and Youth, ANGCY) in recreational facilities. In-depth semi-structured interviews were conducted. Data were analysed using directed content analysis. Food services in recreational facilities. Seven managers from industry participated; five from companies that had adopted and implemented the ANGCY (adopters) in recreational facilities and two from companies that had not (non-adopters). Industry views nutrition guidelines through the lens of profitability. Non-adopters were unwilling to implement the ANGCY for fear of sacrificing short-term profitability, whereas adopters adhered to them in an attempt to position themselves for long-term profitability. Adopters faced barriers including few resources, no training, complex guidelines, low availability of and demand for ANGCY-compliant products, competitive pressures and substantial declines in revenue. Managers believed widespread voluntary adoption of the ANGCY was unlikely without government incentives and/or a mandate, as the environmental context for voluntary action was poor. All managers supported government-mandated implementation of the ANGCY to level the playing field upon which companies compete. Public-private partnerships in recreational facilities can embrace public health goals in the short term, provided industry perceives potential for long-term financial gain. Widespread uptake of voluntary nutrition guidelines in this setting is unlikely, however, as market mechanisms do not encourage industry to sell and promote healthier options. Government legislation may therefore be warranted.

Introduction: Autologous or allogeneic transfer of tumor-infiltrating T-lymphocytes is a promising treatment for metastatic cancers, but a major concern is the difficulty in evaluating cell trafficking and distribution in adoptive cell therapy. This study presents a method of tracking transfusion of T-lymphoblasts in a porcine model by 18 F-2-fluoro-2-deoxy-D-glucose ([ 18 F]FDG) and positron emission tomography. Methods: T-lymphoblasts were labeled with the positron-emitting tracer [ 18 F]FDG through incubation. The T-lymphoblasts were administered into the bloodstream, and the distribution was followed by positron emission tomography for 120 min. The cells were administered either intravenously into the internal jugular vein (n=5) or intraarterially into the ascending aorta (n=1). Two of the pigs given intravenous administration were pretreated with low-molecular-weight dextran sulphate. Results: The cellular kinetics and distribution were readily quantifiable for up to 120 min. High (78.6% of the administered cells) heterogeneous pulmonary uptake was found after completed intravenous transfusion. The pulmonary uptake was decreased either by preincubating and coadministrating the T-lymphoblasts with low-molecular-weight dextran sulphate or by administrating them intraarterially. Conclusions: The present work shows the feasibility of quantitatively monitoring and evaluating cell trafficking and distribution following administration of [ 18 F]FDG-labeled T-lymphoblasts. The protocol can potentially be transferred to the clinical setting with few modifications.

2014-08-01

To investigate whether cosmetic contact lenses (CCL) with surface pigments affect microbial adherence. Fifteen brands of CCL were purchased from optical, non-optical retail outlets, and via the Internet. A standardized rub-off test was performed on each CCL (five lenses per brand) to confirm the location of the pigments. The rub-off test comprised gentle rubbing on the surfaces of each CCL with wetted cotton buds for a maximum of 20 rubs per surface. A new set of CCL (five lenses per brand) were incubated in Pseudomonas aeruginosa overnight. Viable counts of adhered bacteria were determined by the number of colony-forming units (CFU) on agar media on each lens. The adherence of P. aeruginosa as well as Staphylococcus aureus and Serratia marcescens to three brands of CCL (A-C) (five lenses per brand) were also compared to their adherences on their clear counterparts. Only two of the 15 brands of CCL tested (brands B and C) had pigments that did not detach with the rub-off test. The remaining 13 brands of CCL all failed the rub-off test and these lenses showed higher P. aeruginosa adherence (8.7 × 10(5)-1.9 × 10(6) CFU/lens). Brands B and C lenses showed at least six times less bacterial adhesion than the other 13 brands. Compared to their clear counterparts, bacterial adherence to brands B and C lenses did not differ significantly, whereas brand A lenses showed significantly higher adherence. Surface pigments on CCL resulted in significantly higher bacterial adherence. Copyright © 2013 British Contact Lens Association. Published by Elsevier Ltd. All rights reserved.

Despite the boom in new technologically based interventions for people with psychosis, recent studies suggest medium to low rates of adherence to these types of interventions. The benefits will be limited if only a minority of service users adhere and engage; if specific predictors of adherence can be identified then technologies can be adapted to increase the service user benefits. The study aimed to present a systematic review of rates of adherence, dropout, and approaches to analyzing adherence to newly developed mobile and Web-based interventions for people with psychosis. Specific predictors of adherence were also explored. Using keywords (Internet or online or Web-based or website or mobile) AND (bipolar disorder or manic depression or manic depressive illness or manic-depressive psychosis or psychosis or schizophr* or psychotic), the following databases were searched: OVID including MedLine, EMBASE and PsychInfo, Pubmed and Web of Science. The objectives and inclusion criteria for suitable studies were defined following PICOS (population: people with psychosis; intervention: mobile or Internet-based technology; comparison group: no comparison group specified; outcomes: measures of adherence; study design: randomized controlled trials (RCT), feasibility studies, and observational studies) criteria. In addition to measurement and analysis of adherence, two theoretically proposed predictors of adherence were examined: (1) level of support from a clinician or researcher throughout the study, and (2) level of service user involvement in the app or intervention development. We provide a narrative synthesis of the findings and followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for reporting systematic reviews. Of the 20 studies that reported a measure of adherence and a rate of dropout, 5 of these conducted statistical analyses to determine predictors of dropout, 6 analyzed the effects of specific adherence

The lymphocytes from neonatally tolerant rats which adoptively transfer tolerance to sublethally irradiated recipients do so by specificallly suppressing the regeneration of alloreactivity which normally occurs after irradiation. Although tolerant cells will only partially suppress normal alloreactive cells when the two are mixed in near equivalent numbers, experiments in which the interval between injection of tolerant and normal cells into irradiated recipients was gradually extended, indicated that total suppression of normally alloreactive cells was achieved after 8 weeks of prior residence of tolerant cells in the adoptive host. Further evidence that tolerant cells would only suppress if present in excess of normal cells was obtained by reducing the tolerant cell populaton in tolerant donor rats by whole body irradiation. The persistence of tolerance through repeated adoptive transfers was correlated with the persistence of donor (chimeric) cells and the indicator skin graft on adoptive recipients only amplified tolerance expression where the inocula of tolerant cells given was weakly suppressive

Multiple interacting factors influence adherence, and outcomes associated with surgical safety checklists: a qualitative study.

Full Text Available The surgical safety checklist (SSC is meant to enhance patient safety but studies of its impact conflict. This study explored factors that influenced SSC adherence to suggest how its impact could be optimized.Participants were recruited purposively by profession, region, hospital type and time using the SSC. They were asked to describe how the SSC was adopted, associated challenges, perceived impact, and suggestions for improving its use. Grounded theory and thematic analysis were used to collect and analyse data. Findings were interpreted using an implementation fidelity conceptual framework.Fifty-one participants were interviewed (29 nurses, 13 surgeons, 9 anaesthetists; 18 small, 14 large and 19 teaching hospitals; 8 regions; 31 had used the SC for ≤12 months, 20 for 13+ months. The SSC was inconsistently reviewed, and often inaccurately documented as complete. Adherence was influenced by multiple issues. Extensive modification to accommodate existing practice patterns eliminated essential interaction at key time points to discuss patient management. Staff were often absent or not paying attention. They did not feel it was relevant to their work given limited evidence of its effectiveness, and because they were not engaged in its implementation. Organizations provided little support for implementation, training, monitoring and feedback, which are needed to overcome these, and other individual and team factors that challenged SSC adherence. Responses were similar across participants with different characteristics.Multiple processes and factors influenced SSC adherence. This may explain why, in studies evaluating SSC impact, outcomes were variable. Recommendations included continuing education, time for pilot-testing, and engaging all staff in SSC review. Others may use the implementation fidelity framework to plan SSC implementation or evaluate SSC adherence. Further research is needed to establish which SSC components can be modified

The present study seeks to ascertain the attitudes of Portuguese psychology students (future psychologists) toward the development of children adopted by lesbian and gay parents. Each participant (N = 182) read a vignette describing an adoption of a child by lesbian and gay persons. After reading the vignette, participants rated four different aspects of the future development of the adopted child (psychosocial adjustment, victimization, psychological disturbance, and normative sexuality). Furthermore, participants were asked about their gender, interpersonal contact with lesbians and gay men, gender role attitudes, and attitudes toward lesbians and gay men. Future psychologists' attitudes toward the developmental outcomes of children adopted by lesbians and gay men were associated with negative attitudes toward non-heterosexuals, which in turn correlated to interpersonal contact with lesbians and gay men and adherence to gender conservative values. These results clearly highlight the central role of social attitudes and the need for cultural competence training of future psychologists that encourages interpersonal contact with non-heterosexuals and discourages traditional gender roles and negative attitudes toward lesbian and gay men.

Millions of dogs enter animal welfare organizations every year and only a fraction of them are adopted. Despite the most recent American Pet Products Association (APPA) data that nearly half the US population owns a dog, only 20% acquired their dog from an animal welfare organization. Studies show that people consider adopting from an animal shelter more often than they actually do, which indicates a potential market increase if programs can make shelter dogs more visible to adopters. This research focused on a novel adoption program where shelter dogs were transferred into foster homes who were tasked with finding an adopter. Shelter dogs were placed in the path of potential adopters and bypassed the need for the adopter to go to the shelter. The results show that this novel program was effective in a variety of ways including getting dogs adopted. Although length of stay was significantly longer for dogs in the program, the dogs were in a home environment, not taking up kennel space in the shelter. The program also had a lower rate of returns than dogs adopted at the shelter. The foster program tapped adopters in different geographical segments of the community than the dogs adopted from the shelter. By bringing shelter dogs to where adopters spend their time (ex: restaurants, parks, hair salons), the program potentially captured a segment of the population who might have obtained their dog from other sources besides the shelter (such as breeders or pet stores). This novel approach can be an effective method for adoption, has many benefits for shelters, and can tap into a new adopter market by engaging their community in a new way.

Using 323 matched parties of birth mothers and adoptive parents, this study examined the association between the degree of adoption openness (e.g., contact and knowledge between parties) and birth and adoptive parents’ post-adoption adjustment shortly after the adoption placement (6 to 9 months). Data from birth fathers (N=112), an understudied sample, also were explored. Openness was assessed by multiple informants. Results indicated that openness was significantly related to satisfaction with adoption process among adoptive parents and birth mothers. Increased openness was positively associated with birth mothers’ post-placement adjustment as indexed by birth mothers’ self reports and the interviewers’ impression of birth mothers’ adjustment. Birth fathers’ report of openness was associated with their greater satisfaction with the adoption process and better post-adoption adjustment. PMID:18729667

Adoption of the Creative Process According to the Immersive Method

2015-09-01

Full Text Available The immersive method is a new concept of visual education that is better suited to the needs of students in contemporary post-industrial society. The features of the immersive method are: 1 it emerges from interaction with visual culture; 2 it encourages understanding of contemporary art (as an integral part of visual culture; and 3 it implements the strategies and processes of the dominant tendencies in contemporary art (new media art and relational art with the goal of adopting the creative process, expressing one’s thoughts and emotions, and communicating with the environment. The immersive method transfers the creative process from art to the process of creation by the students themselves. This occurs with the mediation of an algorithmic scheme that enables students to adopt ways to solve problems, to express thoughts and emotions, to develop ideas and to transfer these ideas to form, medium and material. The immersive method uses transfer in classes, the therapeutic aspect of art and “flow state” (the optimal experience of being immersed in an activity/aesthetic experience (a total experience that has a beginning, a process and a conclusion/immersive experience (comprehensive immersion in the present moment. This is a state leading to the sublimative effect of creation (identification with what has been expressed, as well as to self-actualisation. The immersive method teaches one to connect the context, social relations and the artwork as a whole in which one lives as an individual. The adopted creative process is implemented in a critical manner on one’s surrounding through analysis, aesthetic interventions, and ecologically and socially aware inclusion in the life of a community. The students gain the crucial meta-competence of a creative thinking process.

Natural killer cells is an important immunological factor in killing malignant cells. Low dose radiation can enhance proliferation and biological activity of NK cell. The involvement of P38MAPK signal pathway and endogenous glutathione induced by LDR may be the probable mechanism. Natural killer cell, especially adherent natural killer cell, is the preferential choice for adoptive cellular immunotherapy, which has a remarkable foreground in malignancy therapy.(authors)

The recent tremendous successes in clinical trials take cancer immunotherapy into a new era and have attracted major attention from both academia and industry. Among the variety of immunotherapy strategies developed to boost patients' own immune systems to fight against malignant cells, the pathogen-based and adoptive cell transfer therapies have shown the most promise for treating multiple types of cancer. Pathogen-based therapies could either break the immune tolerance to enhance the effectiveness of cancer vaccines or directly infect and kill cancer cells. Adoptive cell transfer can induce a strong durable antitumor response, with recent advances including engineering dual specificity into T cells to recognize multiple antigens and improving the metabolic fitness of transferred cells. In this review, we focus on the recent prospects in these two areas and summarize some ongoing studies that represent potential advancements for anticancer immunotherapy, including testing combinations of these two strategies.

Adoptive transfer of EBV specific CD8+ T cell clones can transiently control EBV infection in humanized mice.

Full Text Available Epstein Barr virus (EBV infection expands CD8+ T cells specific for lytic antigens to high frequencies during symptomatic primary infection, and maintains these at significant numbers during persistence. Despite this, the protective function of these lytic EBV antigen-specific cytotoxic CD8+ T cells remains unclear. Here we demonstrate that lytic EBV replication does not significantly contribute to virus-induced B cell proliferation in vitro and in vivo in a mouse model with reconstituted human immune system components (huNSG mice. However, we report a trend to reduction of EBV-induced lymphoproliferation outside of lymphoid organs upon diminished lytic replication. Moreover, we could demonstrate that CD8+ T cells against the lytic EBV antigen BMLF1 can eliminate lytically replicating EBV-transformed B cells from lymphoblastoid cell lines (LCLs and in vivo, thereby transiently controlling high viremia after adoptive transfer into EBV infected huNSG mice. These findings suggest a protective function for lytic EBV antigen-specific CD8+ T cells against EBV infection and against virus-associated tumors in extra-lymphoid organs. These specificities should be explored for EBV-specific vaccine development.

2015-01-01

Cystic fibrosis (CF) health care professionals recognize the need to motivate people with CF to adhere to nebulizer treatments, yet little is known about how best to achieve this. We aimed to produce motivational posters to support nebulizer adherence by using social marketing involving people with CF in the development of those posters. The Sheffield CF multidisciplinary team produced preliminary ideas that were elaborated upon with semi-structured interviews among people with CF to explore barriers and facilitators to the use of nebulized therapy. Initial themes and poster designs were refined using an online focus group to finalize the poster designs. People with CF preferred aspirational posters describing what could be achieved through adherence in contrast to posters that highlighted the adverse consequences of nonadherence. A total of 14 posters were produced through this process. People with CF can be engaged to develop promotional material to support adherence, providing a unique perspective differing from that of the CF multidisciplinary team. Further research is needed to evaluate the effectiveness of these posters to support nebulizer adherence.

Motivations for enterprise system adoption in transition economies: insights from Poland

Soja, Piotr; Weistroffer, Heinz Roland

2016-06-01

Enterprise system (ES) adoption can bring many benefits, but may also put tremendous strain on an organisation or business, sometimes with disastrous outcomes. The specific motivations and expectations that lead to ES adoption may impact the success or failure of these endeavours, and understanding these motivations may be useful in predicting the success of ES projects. Most of the published research on ES adoption motivation has been in the context of highly developed countries. The social, cultural, economic and political conditions in developing, emerging and transition economies make for a different business environment, and insights obtained from developed countries may not always transfer to these settings. This study seeks to identify and help understand the motivations for ES adoption specifically in transition economies, as these economies play a significant role in the global market, but have not been receiving adequate research attention. Drawing on the experience of 129 ES adopters in Poland, a transition economy, this study categorises motivations into coherent groups of issues and evaluates the influence of discovered motivations on ES adoption success. Further, motivations revealed by this study are compared with motivations reported by prior research conducted in developed countries.

There are strong pedagogical arguments in favor of adopting computer-based assessment. The risks of technical failure can be managed and are offset by improvements in cost-effectiveness and quality assurance capability. Academic, administrative, and technical leads at an appropriately senior level within an institution need to be identified, so that they can act as effective advocates. All stakeholder groups need to be represented in undertaking a detailed appraisal of requirements and shortlisting software based on core functionality, summative assessment life cycle needs, external compatibility, security, and usability. Any software that is a candidate for adoption should be trialed under simulated summative conditions, with all stakeholders having a voice in agreeing the optimum solution. Transfer to a new system should be carefully planned and communicated, with a programme of training established to maximize the success of adoption.

Quality of Interhospital Transfer Communication Practices and Association With Adverse Events on an Internal Medicine Hospitalist Service.

Science.gov (United States)

Borofsky, Jennifer S; Bartsch, Jason C; Howard, Alan B; Repp, Allen B

Communication practices around interhospital transfer have not been rigorously assessed in adult medicine patients. Furthermore, the clinical implications of such practices have not been reported. This case-control study was designed to assess the quality of communication between clinicians during interhospital transfer and to determine if posttransfer adverse events (PTAEs) are associated with suboptimal communication. Cases included patients transferred to a Medicine Hospitalist Service from an outside hospital who subsequently experienced a PTAE, defined as unplanned transfer to an intensive care unit or death within 24 hours of transfer. Control patients also underwent interhospital transfer but did not experience a PTAE. A blinded investigator retrospectively reviewed the recorded pretransfer phone conversations between sending and receiving clinicians for adherence to a set of 13 empiric best practice communication elements. The primary outcome was the mean communication score, on a scale of 0-13. Mean scores between PTAE (8.3; 95% confidence interval [CI], 7.6-8.9) and control groups (7.9; 95% CI, 7.1-8.8) did not differ significantly (p = .50), although suboptimal communication on a subset of these elements was associated with increased PTAEs. Communication around interhospital transfer appears suboptimal compared with an empiric set of standard communication elements. Posttransfer adverse events were not associated with aggregate adherence to these standards.

Full Text Available Freedom of contract principle brings the contracting parties to sign into an agreement in such forms, including a standard contract. The standard contracts are made by one party, usually by business entities in the aim of doing efficiency. The contracts, however, potentially contains abuse of power in its application, known as adhesion contract. In term of adhesion contract, it contains prompt restrictions and/or transfer of responsibilities of the business risks to the adhered party. Therefore, good faith principle plays an important role to evaluate the implementation of the adhesion contract. This article discusses the adhesion contract in the light of the basic principles in contract law and explores the legal frameworks for adhered party to seek their contractual rights in conjunction with the implementation of the adhesion contract. We also compare the implementation of the adhesion contract, practically, both in Indonesia and international practices by examining the national laws and the model law e.g. Principles of International Commercial Contracts (PICC.

Adolescents with extreme obesity, who have undergone bariatric surgery, must adhere to many lifestyle and nutritional recommendations, including multivitamin therapy. Little is known about multivitamin adherence following adolescent bariatric surgery. The present study aims to document self-reported and electronically-monitored adherence to multivitamins, determine convergence between self-report and electronic monitoring adherence for multivitamins, and identify barriers to multivitamin adherence for adolescents who have undergone bariatric surgery. The study used a prospective, longitudinal observational design to assess subjective (self-reported) and objective (electronic monitors) multivitamin adherence in a cohort of 41 adolescents (Mean age = 17.1 ± 1.5; range = 13-19) who have undergone bariatric surgery at Cincinnati Children's Hospital Medical Center. Mean adherence as derived from electronic monitoring for the entire 6-month study period was 29.8% ± 23.9. Self-reported adherence was significantly higher than electronically monitored adherence across both the 1 and 6-month assessment points (z = 4.5, P bariatric surgery, high rates of nonadherence to multivitamin therapy were observed in adolescents who had undergone bariatric surgery with forgetting and difficulty swallowing pills as reported barriers to adherence. These high rates of nonadherence to multivitamin therapy should be considered when devising treatment and family education pathways for adolescents considering weight loss surgery.

Improved communication from physician- patient emailing is an important element of patient centeredness. Physician-patient email use has been low; and previous data from Florida suggest that physicians who email with patients rarely implement best-practice guidelines designed to protect physicians and patients. Our objective was to examine whether email use with patients has changed over time (2005-2008) by using two surveys of Florida physicians, and to determine whether physicians have more readily embraced the best-practice guidelines in 2008 versus 2005. Lastly, we explored the 2008 factors associated with email use with patients and determined whether these factors changed relative to 2005. Our pooled time-series design used results from a 2005 survey (targeting 14,921 physicians) and a separate 2008 survey (targeting 7003 different physicians). In both years, physicians practicing in the outpatient setting were targeted with proportionally identical sampling strategies. Combined data from questions focusing on email use were analyzed using chi-square analysis, Fisher exact test, and logistic regression. A combined 6260 responses were available for analyses, representing a participation rate of 28.2% (4203/14,921) in 2005 and 29.4% (2057/7003) in 2008. Relative to 2005, respondents in 2008 were more likely to indicate that they personally used email with patients (690/4148, 16.6% vs 408/2001, 20.4%, c(2) (1) = 13.0, P email with patients did not change from 2005 to 2008 (2.9% vs 59/2001, 2.9%). Interest among physicians in future email use with patients was lower in 2008 (58.4% vs 52.8%, c(2) (2) = 16.6, P email best practices remained low in 2008. When comparing 2005 and 2008 adherences with each of the individual guidelines, rates decreased over time in each category and were significantly lower for 4 of the 13 guidelines. Physician characteristics in 2008 that predicted email use with patients were different from 2005. Specifically, in multivariate analysis

Many factors are associated with medication non-adherence in Parkinson's disease (PD), including complex treatment regimens, mood disorders and impaired cognition. However, interventions to improve adherence which acknowledge such factors are lacking. A phase II randomised controlled trial was conducted investigating whether Adherence Therapy (AT) improves medication adherence and quality of life (QoL) compared with routine care (RC) in PD. Eligible PD patients and their spouse/carers were randomised to intervention (RC plus AT) or control (RC alone). Primary outcomes were change in adherence (Morisky Medication Adherence Scale) and QoL (Parkinson's Disease Questionnaire-39) from baseline to week-12 follow up. Secondary outcomes were MDS-UPDRS (part I, II, IV), Beliefs about Medication Questionnaire (BMQ), EuroQol (EQ-5D) and the Caregiving Distress Scale. Blinded data were analysed using logistic and linear regression models based on the intention-to-treat principle. Seventy-six patients and 46 spouse/carers completed the study (intervention: n = 38 patients, n = 24 spouse/carers). At week-12 AT significantly improved adherence compared with RC (OR 8.2; 95% CI: 2.8, 24.3). Numbers needed to treat (NNT) were 2.2 (CI: 1.6, 3.9). Compared with RC, AT significantly improved PDQ-39 (-9.0 CI: -12.2, -5.8), BMQ general harm (-1.0 CI: -1.9, -0.2) and MDS-UPDRS part II (-4.8 CI: -8.1, -1.4). No significant interaction was observed between the presence of a spouse/carer and the effect of AT. Adherence Therapy improved self-reported adherence and QoL in a PD sample. The small NNT suggests AT may be cost-effective. A larger pragmatic trial to test the efficacy and cost-effectiveness of AT by multiple therapists is required. © 2014 John Wiley & Sons Ltd.

The Texas Adoption Project: adopted children and their intellectual resemblance to biological and adoptive parents.

Science.gov (United States)

Horn, J M

1983-04-01

Intelligence test scores were obtained from parents and children in 300 adoptive families and compared with similar measures available for the biological mothers of the same adopted children. Results supported the hypothesis that genetic variability is an important influence in the development of individual differences for intelligence. The most salient finding was that adopted children resemble their biological mothers more than they resemble the adoptive parents who reared them from birth. A small subset of the oldest adopted children did not resemble their biological mothers. The suggestion that the influence of genes declines with age is treated with caution since other adoption studies report a trend in the opposite direction.

This study aimed to evaluate agreement between children and parents on a measure of behavioral and pharmacological adherence in children with sickle cell disease (SCD), and the associations among family factors (i.e., problem-solving skills, routines, communication) and adherence behaviors. In all, 85 children (aged 8-18 years) with SCD and their parents completed questionnaires assessing individual and family factors. Overall parent-child agreement on an adherence measure was poor, particularly for boys and older children. Greater use of child routines was associated with better overall child-reported adherence. Open family communication was associated with higher overall parent-reported adherence. While further research is needed before definitive conclusions can be drawn, results suggest the need to assess child adherence behaviors via both child and parent reports. Findings also suggest that more daily family routines and open family communication may be protective factors for better disease management. © The Author 2017.

Barriers to medication adherence stem from multiple factors. An effective and convenient tool is needed to identify these barriers so that clinicians can provide a tailored, patient-centered consultation with patients. The Modified Drug Adherence Work-up Tool (M-DRAW) was developed as a 13-item checklist questionnaire to identify barriers to medication adherence. The response scale was a 4-point Likert scale of frequency of occurrence (1 = never to 4 = often). The checklist was accompanied by a GUIDE that provided corresponding motivational interview-based intervention strategies for each identified barrier. The current pilot study examined the psychometric properties of the M-DRAW checklist (reliability, responsiveness and discriminant validity) in patients taking one or more prescription medication(s) for chronic conditions. A cross-sectional sample of 26 patients was recruited between December 2015 and March 2016 at an academic medical center pharmacy in Southern California. A priming question that assessed self-reported adherence was used to separate participants into the control group of 17 "adherers" (65.4%), and into the intervention group of nine "unintentional and intentional non-adherers" (34.6%). Comparable baseline characteristics were observed between the two groups. The M-DRAW checklist showed acceptable reliability (13 item; alpha = 0.74) for identifying factors and barriers leading to medication non-adherence. Discriminant validity of the tool and the priming question was established by the four-fold number of barriers to adherence identified within the self-selected intervention group compared to the control group (4.4 versus 1.2 barriers, p tool will include construct validation.

Adherence of non-pharmaceutically sponsored oncology trial protocols to the International Conference on Harmonization (ICH) guidelines in an academic institution outside the ICH jurisdictions and the impact of IRB implementation on this adherence

Zeeneldin, A.A.

2013-01-01

Purpose: To assess adherence of non-pharmaceutically sponsored trials (non-PSTs) to ICH protocol structure guidelines and to estimate the effect of implementing Institutional Review Boards (IRB) review on this adherence. Methods: This is a retrospective exploratory study where 60 non-PST clinical trial protocols (CTPs) were reviewed and halved to IRB-reviewed CTPs (IRCTPs) and non-lRB-reviewed CTPs (non-lRCTPs). Adherence score (AS) was calculated as the number of fulfilled items or sub-items divided by their total number. Results: Three adherence patterns were encountered: (1) items consistently present in both groups e.g. general and background information, objectives, inclusion criteria and intervention details, (2) items consistently absent in both groups and included contact information of investigators and trial sites, product accountability, randomization codes management, interim analyses and many other statistical aspects, and (3) items variably present in both groups where the effect of IRB was verifiable. Trial site details, potential benefits, discontinuation and exclusion criteria, and follow up for adverse events were more encountered in IRCTPs than non-IRCTPs. Withdrawal criteria monitoring of treatment compliance showed a reverse pattern (p < 0.05 for all). The total AS, administrative AS and ethics AS for IRCTPs was 43%, 22% and 70% compared to 38%, 16% and 33% for non-IRCTPs (p < 0.003, <0.001, 0.004), respectively. The scientific AS was 54% for both groups (p = 0.87). Conclusions: IRB-implementation at NCl-Egypt improved ethical and administrative sections of academic protocols. However, this improvement is modest and needs further actions including adoption of protocol templates. Scientific sections were as good after IRB-implementation as they were before that

Study Objectives: Adherence to CPAP therapy is low in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS). The purpose of the present study was to evaluate the utility of measures of sleep architecture and sleep continuity on the CPAP titration study as predictors of both short- and long-term CPAP adherence. Methods: 93 patients with OSAHS (RDI 42.8 ± 34.3/h) underwent in-laboratory diagnostic polysomnography, CPAP titration, and follow-up polysomnography (NPSG) on CPAP. Adherence to CPAP was objectively monitored. Short-term (ST) CPAP adherence was averaged over 14 days immediately following the titration study. Long-term (LT) CPAP adherence was obtained in 56/93 patients after approximately 2 months of CPAP use. Patients were grouped into CPAP adherence groups for ST ( 4 h) and LT adherence ( 4 h). Sleep architecture, sleep disordered breathing (SDB) indices, and daytime outcome variables from the diagnostic and titration NPSGs were compared between CPAP adherence groups. Results: There was a significant relationship between ST and LT CPAP adherence (r = 0.81, p CPAP adherence groups had significantly lower %N2 and greater %REM on the titration NPSG. A model combining change in sleep efficiency and change in sleep continuity between the diagnostic and titration NPSGs predicted 17% of the variance in LT adherence (p = 0.006). Conclusions: These findings demonstrate that characteristics of sleep architecture, even on the titration NPSG, may predict some of the variance in CPAP adherence. Better sleep quality on the titration night was related to better CPAP adherence, suggesting that interventions to improve sleep on/prior to the CPAP titration study might be used as a therapeutic intervention to improve CPAP adherence.

2016-01-01

Full Text Available Abstract Communication about adoption is a family interaction process which is more than the simple exchange of information. Adoption communication can be characterized in terms of the level of openness of family conversations regarding the child’s past and the degree of the family’s adoption social disclosure. The objective of this study is to explore the process of adoption communication openness in Portuguese adoptive families by identifying the impact of variables related to the adoption process, the adoptive parenting and the adoptee. One hundred twenty five parents of children aged 3 to 15, who were adopted on average 4 years ago, participated in this study. Data was collected during home visits using the Parents Adoption Process Interview. A cluster analysis identified three different groups of families according to the level of adoption communication openness within the family and outside. The findings also showed that the process of the adoption communication openness started when parents decided to adopt, developed in parent-child interaction and was susceptible to change under professional intervention. The relevance of training given to prospective adopters and of professional practice based on scientific evidence is highlighted.

Adopted children in their adoptive families.

The adoptive process can produce unusual stresses on the child, and biologic and adoptive parents, from prenatal to postnatal life, and through the various phases of physical and pscyhological development. Because of the possibility of these children and their families falling into the "at risk" category with greater potential for psychological and social problems, the pediatrician is of primary importance in diagnosis and counseling. The pediatrician can be of major help in properly diagnosing emotional, behavioral and/or learning problems occurring in adopted children. There must be a thorough evaluation of the child and his family to understand and properly treat symptomatic behavior. The pediatrician can give advice regarding developmental milestones, and especially help the adoptive parents in appreciating their conscious and unconscious attitudes so as to enhance attachment behaviors. Pediatricians are the consultants to whom parents turn for advice regarding the timing of telling about adoption. This advice needs to be individualized according to the specific child's needs. Using a developmental conceptual framework, the pediatrician is in the best position to help the parents and their adopted children with their feelings about societal attitudes and how these can most appropriately be handled. Along this line, the pediatrician can give help and advice when and if the adoptee decides to search for his biologic parents. There is a need to clarify laws which seal the original birth certificate permitting those adoptees who wish to attain a knowledge of potentially related disease processes and an identity with his own genealogical past to do so. This would also allow the adoptee to offer his own children information about their own genetic pool and an awareness of adoption as one of the most valuable and historically significant child rearing practices.

Mechanisms of immunological eradication of a syngeneic guinea pig tumor. II. Effect of methotrexate treatment and T cell depletion of the recipient on adoptive immunity

Shu, S.; Fonseca, L.S.; Hunter, J.T.; Rapp, H.J.

The influence of methotrexate on the development of immunity to the line 10 hepatoma was studied in guinea pigs. Chronic methotrexate treatment had no apparent effect on the ability of immune guinea pigs to suppress the growth of inoculated tumor cells. In contrast, the same methotrexate regimen inhibited the development of tumor immunity if started before the 8th day after immunization with a vaccine containing viable line 10 cells admixed with Bacillus Calmette-Guerin (BCG) cell walls. Thus, methotrexate selectively inhibited the afferent limb of the immune response. In adoptive transfer experiments, methotrexate-treated recipient guinea pigs were capable of being passively sensitized with immune spleen cells, indicating that the primary cell-mediated immune response of the recipient was not required for adoptive immunity. The contribution of recipient T cells in adoptive immunity was further investigated in guinea pigs deleted of T cells by thymectomy, irradiation, and bone marrow reconstitution. Despite demonstrable deficiency in T lymphocyte reactions, B animals were fully capable of rejecting tumors after transfer of immune cells. These results suggest that the expression of adoptive immunity was independent of recipient T cell participation. In addition, sublethal irradiation of immune spleen cells prior to adoptive transfer abolished their efficacy. Proliferation of transferred immune cells in the recipient may be essential for expression of adoptive immunity

The primary purpose of this article is to document whether demographic, clinical, regimen-related, intrapersonal, and interpersonal factors predict medication non-adherence for vasculitis patients. A secondary purpose is to explore whether adherence varies by medication type and whether patients experienced drug-related side effects. Vasculitis patients (n=228) completed online baseline and 3-month follow-up surveys. Demographic (age, gender, education, race, marital status, and insurance status), clinical (perceived vasculitis severity, disease duration, vasculitis type, and relapse/remission status), regimen-related (experience of side effects), intrapersonal (depressive symptoms), and interpersonal (adherence-related support from family and friends) factors were measured at baseline. Medication non-adherence was assessed at follow-up using the Vasculitis Self-Management Survey medication adherence sub-scale (α=0.89). Variables that significantly correlated (pvasculitis medication types, patients who experienced side effects were less adherent than patients who did not experience side effects. Multiple factors are associated with medication non-adherence for vasculitis patients. Providers should discuss medication adherence and drug-related side effects with vasculitis patients. Providers may want to particularly target younger patients and patients with clinical signs of depression. PMID:23314654

Little information is available on adherence to a home automated peritoneal dialysis (APD) prescription for children with end-stage renal disease. We have therefore retrospectively reviewed HomeChoice PRO Card data from patients Adherence was characterized as occurring ≥ 95%, 90-94%, or treatment adherence and patient age, gender, race and if the patient had received training, respectively, was assessed. Of the 51 patients (57% male), with a mean age at peritoneal dialysis (PD) onset of 11.8 ± 5.3 years, 28 (55%) were adherent for all variables. No difference in mean age or if patients were trained existed between the two groups. Males were more likely to be non-adherent (p = 0.026) as were African Americans (p = 0.048). The majority of patients were adherent to duration (96%) and number of cycles (92%), whereas non-adherence was more common with number of sessions (82%) and dialysate volume (78%). In conclusion, 45% of the pediatric patients in our study cohort exhibited some non-adherence to their prescribed APD regimen, emphasizing the value of closely monitoring the performance of home dialysis in children.

Adoptions today increasingly include contact between adoptive and birth families. What do these "open adoptions" look like? How do the participants feel about them? This article, based on part of a longitudinal study that first examined adoptive parents' perceptions of their infants' open adoptions seven years ago, explores the parents' reactions now that their children are school age. This qualitative descriptive research revealed changes in the openness in the adoptions over time and identified four dimensions along which open adoptions vary. Findings showed parents' enthusiasm for the openness in their adoptions, regardless of the type and extent of openness. Implications for social work practice, education, and policy are explored.

Full Text Available Purpose: Bacterial adherence to intraocular lenses (IOLs has been incriminated in the pathogenesis of postoperative endophthalmitis. Staphylococcus epidermidis is the most common organism isolated. We studied the in-vitro adhesion of Staphylococcus epidermidis to Polymethylmethacrylate (PMMA IOLs and the effect of duration of exposure to adherence. Methods: Two groups of 10 IOLs each were incubated in Staphylococcus epidermidis suspension for 2 minutes and 20 minutes respectively. Adhesion of bacterial cells was determined by counting the number of viable bacteria attached to IOLs. Results: The mean bacterial adherence with 2 minutes incubation was 12,889 ± 7,150 bacteria / IOL and with 20 minutes incubation was 84,226 ± 35,024 bacteria/IOL (P< 0.01. Conclusion: Our results show that Staphylococcus epidermidis adheres to PMMA IOLs in vitro and the degree of adherence is less for shorter duration of exposure. We conclude that viable bacteria irreversibly adherent to IOLs may play a role in the pathogenesis of postoperative endophthalmitis. Shorter duration of operative manipulation and exposure to contaminating sources may decrease the chances of postoperative endophthalmitis.

The primary objectives of this study were to determine the association between alcohol and antiretroviral therapy (ART) adherence and the perceived appropriateness and acceptability of elements of an adherence counseling program with a focus on alcohol-related ART nonadherence among a sample of ART recipients in human immunodeficiency virus (HIV) clinics in Tshwane, South Africa. We conducted a cross-sectional study with purposive sampling. The sample comprised 304 male and female ART recipients at two President's Emergency Plan For AIDS Relief-supported HIV clinics. Using an interview schedule, we assessed patients' alcohol use (Alcohol Use Disorders Identification Test), other drug use, level of adherence to ART, and reasons for missing ART doses (AIDS Clinical Trials Group adherence instrument). Additionally, patients' views were solicited on: the likely effectiveness of potential facilitators; the preferred quantity, duration, format, and setting of the sessions; the usefulness of having family members/friends attend sessions along with the patient; and potential skill sets to be imparted. About half of the male drinkers' and three quarters of the female drinkers' Alcohol Use Disorders Identification Test scores were suggestive of hazardous or harmful drinking. Average self-reported ART adherence was 89.7%. There was a significant association between level of alcohol use and degree of ART adherence. Overall, participants perceived two clinic-based sessions, each of one hour's duration, in a group format, and facilitated by a peer or adherence counselor, as most appropriate and acceptable. Participants also had a favorable attitude towards family and friends accompanying them to the sessions. They also favored an alcohol-focused adherence counseling program that employs motivational interviewing and cognitive behavioral therapy-type approaches. The association between alcohol use and ART nonadherence points to a need for alcohol-focused ART adherence

Though efficacious and affordable treatments for gout are widely available, gout is still not well controlled in many countries of the world including China.To investigate patient adherence to gout management recommendations and potential barriers in Chinese male gout patients, a survey was carried out by telephone interview in male patients registered in the gout clinic at Peking Union Medical College Hospital. Adherence to dietary and medication recommendations was measured by a food frequency questionnaire and proportion of cumulative time adherent to chemical urate-lowering therapy (ULT), respectively. Dietary adherence was defined as consumption of alcohol, seafood and animal organs less than once per month, and reduced red meat after dietary counseling. Medication adherence was defined as ULT ≥80% of time in the past 12 months for patients with indications. Logistic regression models were used to identify patient characteristics associated with management adherence. Reasons for nonadherence were also sought by open-end questions.Dietary and medication adherence were 44.2% and 21.9%, respectively. Older age (odds ratio [OR] 7.90, 95% confidence interval [CI] 2.49-25.04 for age ≥60), higher serum uric acid (sUA) levels (OR 3.53, 95% CI 1.42-8.75 for the highest quartile), and tophi (OR 2.31, 95% CI 1.12-4.77) were associated with dietary adherence independently, while tophi (OR 14.05, 95% CI 2.67-74.08) and chronic kidney disease (OR 16.66, 95% CI 2.63-105.37) were associated with medication adherence independently. Reasons that patients reported for nonadherence to medication included remission after treatment (35.3%), concerns for potential side effects (22.7%), insufficient patient education (8.7%), and adverse events (8.2%).Patient adherence to gout management recommendations is poor in China. Older age, increased disease burden, and specific comorbidities were associated with management adherence.

Full Text Available ABSTRACT Objective: The aim of this study was to investigate pharmacological treatment adherence of patients with juvenile idiopathic arthritis, attended in an outpatient pharmacy at a tertiary hospital in northeastern Brazil. Methods: The analysis of adherence was performed along with caregivers, through a structured questionnaire based on Morisky, Green and Levine, which enabled the categorization of adherence in “highest”, “moderate” or “low” grades, and through evaluating medication dispensing registers, which classified the act of getting medications at the pharmacy as “regular” or “irregular”. Drug Related Problems (DRP were identified through the narrative of caregivers and classified according to the Second Granada Consensus. Then, a pharmaceutical orientation chart with information about the therapeutic regimen was applied, in order to function as a guide for issues that influenced adherence. Results: A total of 43 patients was included, with a mean age of 11.12 years, and 65.1% (n = 28 were female. Applying the questionnaire, it was found “highest” adherence in 46.5% (n = 20 patients, “moderate” adherence in 48.8% (n = 21, and “low” adherence in 4.7% (n = 2. Through an analysis of the medication dispensing registers, a lower level of adherence was observed: only 25.6% (n = 11 of the participants received “regularly” the medications. Twenty-six DRP was identified, and 84.6% (n = 22 were classified as real. There were no significant associations between socio-demographic variables and adherence, although some caregivers have reported difficulty in accessing the medicines and in understanding the treatment. Conclusion: Our findings showed problems in the adherence process related to inattention, forgetfulness and irregularity in getting medicines, reinforcing the need for the development of strategies to facilitate a better understanding of treatment and to ensure adherence.

There is increasing attention on the role of community pharmacists in improving medication adherence. There is a need to better understand pharmacist attitudes and experiences related to this role. To assess community pharmacist perceptions of patient reasons for non-adherence, characterize the adherence beliefs of community pharmacists, and test if there are demographic predictors of pharmacists' self-efficacy, outcome expectations, and role beliefs related to intervening on medication non-adherence. A cross-sectional survey was mailed using a 4-contact approach to 1000 pharmacists practicing in 5 Midwestern U.S. States. The survey included seven domains to address the study objectives. Descriptive statistics were calculated for demographic items, coefficient alphas tested the internal consistency of scales, and multiple regression was used to test the relationship between demographics and scale means. There were 261 usable responses giving a 29% response rate. Pharmacists perceived forgetting and instructions changing without a new prescription to be the most common reasons for late refills. A minority of pharmacists agreed that non-adherence involves a deliberate decision or that negative medication beliefs were common reasons for late refills. Pharmacists were confident, had positive outcome expectations, and positive role beliefs related to interacting with patients who have adherence issues. Barriers to adherence intervention included difficulties with follow-up and documentation. Also, over half of the pharmacists reported that discussing adherence makes patients defensive. Pharmacists had positive attitudes toward intervening on medication non-adherence although barriers to intervention are present. Pharmacists perceived non-intentional reasons for late refills to be more prevalent than intentional reasons. Pharmacists may benefit from additional non-adherence communication training and support targeted at identifying a broader range of non-adherence

Abstract Background As the problem of patient non-adherence persists and a solution appears hard to be found, it continues to be important to look for new ways to further the issue. We recently conducted a meta-review of adherence intervention studies which yielded a preliminary agenda for future research, practice and theory development in patient adherence. The objective of the present project was to find out to what extent adherence experts consider this agenda relevant and feasible. Metho...

Nonadherence to immunosuppressive (IS) therapy is associated with poor outcomes. Identifying factors predicting poor adherence is therefore essential. The primary objective of this study was to test whether parameters of a model adapted from the theory of planned behavior, and more specifically attitudes that are influenced by beliefs and satisfaction with medication, could predict adherence in solid organ transplant patients. Adherence was assessed with a self-reported medication adherence scale and IS blood trough concentrations over 6 months, in four transplant units. Satisfaction and beliefs were assessed using the Treatment Satisfaction with Medicines Questionnaire (SATMED-Q) and Beliefs about Medicines Questionnaire (BMQ), respectively. Theory of planned behavior was assessed with a specific questionnaire exploring intentions, subjective norms, attitudes and perceived behavioral control. Treatment characteristics and socioeconomic data were also collected. One hundred and fifty-three solid organ transplant patients were enrolled, including lung (n=33), heart (n=43), liver (n=42), and kidney (n=44) patients. Satisfaction and positive beliefs about medication were higher in adherent than those in nonadherent patients. Factors independently associated with an increased risk of nonadherence were negative general beliefs about medications (odds ratio [OR]=0.89 [0.83-0.97]), living alone (OR=2.78 [1.09-7.09]), heart transplantation (OR=3.49 [1.34-9.09]), and being on everolimus (OR=5.02 [1.21-20.8]). Negative beliefs toward medications were shown to be an independent risk factor of poor adherence. Therefore, the BMQ could be an effective, easy to implement tool, for use in everyday practice, to identify patients needing interventions to improve adherence to IS.

Adherence is defined as the extent to which a person's behavior corresponds with recommendations from health care providers. Adherence to treatment is an important factor for a good therapeutic outcome. This study aimed to examine the adherence of patients with tinea pedis and to clarify the factors related to it. We assessed medication adherence for oral and topical drugs using a translated version of the Morisky Medication Adherence Scale-8 (MMAS-8) together with other background factors in 445 Japanese patients with tinea pedis, using a questionnaire in a web-based monitoring system. Overall, high, medium and low adherence rates as assessed by MMAS-8 were 8.7%, 31.7% and 59.6% for oral medication, and 8.6%, 17.4% and 74.0% for topical medication, respectively. The adherence level was significantly higher for oral medication than for topical medication. Subgroup analyses showed that the adherence level for topical medication was significantly higher when topical and oral medications were used in combination than when topical medication was used alone. A low adherence level was shown in employed patients, those for whom their oral medication had not been effective and those with topical medication who had visited their hospital less often than once every six months. Patient adherence to therapy can be effectively improved by selecting highly effective medication while considering the prescription of topical and oral antifungal medications concomitantly, by carefully selecting a therapy plan for employed patients and by encouraging patients to visit their doctor regularly.

Comprehensive genetic assessment of the human embryo: can empiric application of microarray comparative genomic hybridization reduce multiple gestation rate by single fresh blastocyst transfer?

The unacceptable multiple gestation rate currently associated with in vitro fertilization (IVF) would be substantially alleviated if the routine practice of transferring more than one embryo were reconsidered. While transferring a single embryo is an effective method to reduce the clinical problem of multiple gestation, rigid adherence to this approach has been criticized for negatively impacting clinical pregnancy success in IVF. In general, single embryo transfer is viewed cautiously by IVF patients although greater acceptance would result from a more effective embryo selection method. Selection of one embryo for fresh transfer on the basis of chromosomal normalcy should achieve the dual objective of maintaining satisfactory clinical pregnancy rates and minimizing the multiple gestation problem, because embryo aneuploidy is a major contributing factor in implantation failure and miscarriage in IVF. The initial techniques for preimplantation genetic screening unfortunately lacked sufficient sensitivity and did not yield the expected results in IVF. However, newer molecular genetic methods could be incorporated with standard IVF to bring the goal of single embryo transfer within reach. Aiming to make multiple embryo transfers obsolete and unnecessary, and recognizing that array comparative genomic hybridization (aCGH) will typically require an additional 12 h of laboratory time to complete, we propose adopting aCGH for mainstream use in clinical IVF practice. As aCGH technology continues to develop and becomes increasingly available at lower cost, it may soon be considered unusual for IVF laboratories to select a single embryo for fresh transfer without regard to its chromosomal competency. In this report, we provide a rationale supporting aCGH as the preferred methodology to provide a comprehensive genetic assessment of the single embryo before fresh transfer in IVF. The logistics and cost of integrating aCGH with IVF to enable fresh embryo transfer are also

Bacterial adherence to extended wear soft contact lenses

The authors studied the adherence of Pseudomonas aeruginosa and Staphylococcus aureus to extended wear soft contact lenses (EWSCLs) with and without focal deposits using both a radiolabeling technique and electron microscopy. P. aeruginosa showed significant adherence to contact lenses in vitro. In contrast, S. aureus failed to show significant adherence to contact lenses in vitro (i.e., the radioactive uptake was not significantly above background). The extent of adherence of Pseudomonas was proportional to the number of focal deposits on the lenses. Results of electron microscopic examination showed the bacteria to be adherent primarily to large focal deposits (greater than or equal to 150 microns). There was no pseudomonal adherence to the small focal deposits (less than or equal to 50 microns) and little adherence to the areas in between the focal deposits. The authors hypothesize that worn lenses, especially those with large focal deposits, serve as a vehicle for the transport of P. aeruginosa to the cornea. This hypothesis could be a partial explanation for the high incidence of keratitis caused by P. aeruginosa in EWSCL patients

The purpose of this study was to evaluate adherence and identify predictors of adherence to a raw vegan diet (i.e., uncooked plant foods) following a stay at a raw vegan institute. In this cohort study of guests at a raw vegan institute, subjects completed written questionnaires upon arrival and 12 weeks later. Of 107 eligible guests, 84 participated. Mean age was 54 years, 23 were male, and 73 white. Fifty-one completed the 12-week follow-up. Eight (16%) reported their diet to be 80% raw vegan at baseline and 14 (28%) at follow-up. Based on a raw vegan dietary adherence score (range 0-42) created for this study, mean adherence (SD) increased from 15.1 (5.4) to 17.0 (5.8) over 12 weeks (p=0.03). Baseline predictors of adherence included: education (beta=0.95), severity of disease (beta=0.98), and self-efficacy to adhere (beta=0.72). Future interventions that evaluate this diet should address self-efficacy, an important, potentially remediable predictor of adherence.

After two decades of microbicide clinical trials it remains uncertain if vaginally- delivered products will be clearly shown to reduce the risk of HIV infection in women and girls. Furthermore, a microbicide product with demonstrated clinical efficacy must be used correctly and consistently if it is to prevent infection. Information on adherence that can be gleaned from microbicide trials is relevant for future microbicide safety and efficacy trials, pre-licensure implementation trials, Phase IV post-marketing research, and microbicide introduction and delivery. Drawing primarily from data and experience that has emerged from the large-scale microbicide efficacy trials completed to-date, the paper identifies six broad areas of adherence lessons learned: (1) Adherence measurement in clinical trials, (2) Comprehension of use instructions/Instructions for use, (3) Unknown efficacy and its effect on adherence/Messages regarding effectiveness, (4) Partner influence on use, (5) Retention and continuation and (6) Generalizability of trial participants' adherence behavior. Each is discussed, with examples provided from microbicide trials. For each of these adherence topics, recommendations are provided for using trial findings to prepare for future microbicide safety and efficacy trials, Phase IV post-marketing research, and microbicide introduction and delivery programs.

As for ex-vessel spent fuel handling, a transfer pot with two fuel subassembly positions has been developed so as to shorten refueling period increasing plant availability. The pot is required to provide sufficient cooling capability in case of transportation malfunction. In this study, a three dimensional analysis model for heat transfer evaluation of the JSFR fuel transfer pot has been developed. The heat transfer models inside and outside the pot have been validated by reference experiments. Using the developed three-dimensional model, the JSFR fuel transfer pot has been analyzed. For a simpler design tool, a two dimensional analysis model has been developed. Comparison of the three and two dimensional analyses shows that two dimensional analyses could estimate pot cooling performance conservatively.

As medication adherence continues to be a prevalent issue in today's society, the methods used to monitor medication-taking behaviors are constantly being re-evaluated and compared in search of the 'gold standard' measure. Our review aimed to assess the current literature surrounding the correlation between self-reported questionnaires (SRQs) and electronic monitoring devices to determine if these measures produce similar results. We performed a literature search from 2009 to 2017 using PubMed, PubMed In-Process and Non-Indexed, EMBASE, Ovid MEDLINE, and Ovid MEDLINE In-Process. A keyword search using the terms 'patient compliance', 'treatment compliance', 'medication adherence', 'drug monitoring', 'drug therapy', 'electronic', 'digital', 'computer', 'monitor', 'monitoring', 'drug', 'pharmaceutical preparations', 'compliance', and 'medications' was done to capture all articles. We included articles measuring adherence using both monitoring devices and SRQs. Thirty-five articles were included in this review. The average difference in measured adherence rates between the two measures was 9.2% (range -66.3 to 61.5). A majority (62.7%) of articles reported moderate (n = 12; 27.9%), high (n = 5, 11.6%), or significant (n = 10, 23.3%) correlations between SRQs and monitoring devices. Results from our review are consistent with previous studies, as we found that many of our studies produced moderate to high correlation between both SRQs and monitoring devices [Farmer, Clin Ther 21(6):1074-90 (1999), IMS Institute for Healthcare Informatics. Avoidable costs in US health care (2012), Patel et al., Respirology 18(3):546-52 (2013), Siracusa et al., J Cyst Fibros 14(5):621-6 (2015), Smith et al., Int J Cardiol 145(1):122-3 (2010)]. Our findings demonstrate that self-reported adherence produces comparable results to electronic monitoring devices. As there is not yet a 'gold standard' measure for monitoring patient adherence, SRQs and Medication Event Monitoring Systems

In the diffusional phase transformation of two-phase alloys, the new phase precipitates form the matrix phase at specific temperatures, followed by the formation of a mixed microstructure comprising the precipitate and the matrix. It has been found that by specific chemical-etching treatment, the precipitate in Fe-25Cr-6Ni alloy projects substantially and clusters at the surface. The configuration of the precipitate has an extremely high aspect ratio: it is several microns in width and several tens of microns in length (known as micron-spiked). This study targets the development of a gene transfer device with a micro-spike produced based on the self-organization phenomenon of the Fe-25Cr-6Ni alloy. With this spike-projected device, we tried to efficiently transfer plasmid DNA into adherent cells by electric pulse-triggered gene transfer using a plasmid-loaded electrode (electroporation-based reverse transfection). The spiked structure was applied to a substrate of the device to allow efficient gene transfer into adherent cells, although the general substrate was flat and had a smooth surface. The results suggest that this unique spike-projected device has potential applications in gene transfer devices for the analysis of the human genome in the post-genome period.

Objectives: To establish patterns of use and adherence with topical treatments for AK and to identify treatment-related factors that impact on adherence. Methods: A community-based, cross-sectional study was performed using a standardized questionnaire completed online or via telephone interview. Patients were stratified according to the presence of AK lesions on the scalp and/or other extremities; and presence of scarring resulting from treatment. Results: This study included 305 patients with AK who were currently using a patient-applied topical therapy for AK or had used one within the previous 12 months. In total, 88% (n = 268/305 of patients were either non-adherent, non-persistent or both non-adherent and non-persistent to topical therapy. Duration of treatment was associated with increasing rates of non-adherence (adjusted odds ratio [OR]; for treatment durations greater than 4 weeks, 2.2, P < 0.01: 52% of patients were non-adherent with 3–4 week treatment duration; 69% of patients with 4–8 week treatment duration; and 71% of patients with 6–12 week treatment duration.

Does good medication adherence really save payers money?

Despite a growing consensus that better adherence with evidence-based medications can save payers money, assertions of cost offsets may be incomplete if they fail to consider additional drug costs and/or are biased by healthy adherer behaviors unobserved in typical medical claims-based analyses. The objective of this study was to determine whether controlling for healthy adherer bias (HAB) materially affected estimated medical cost offsets and additional drug spending associated with higher adherence. A total of 1273 Medicare beneficiaries with diabetes enrolled in Part D plans between 2006 and 2009. Using survey and claims data from the Medicare Current Beneficiary Survey, we measured medical and drug costs associated with good and poor adherence (proportion of days covered ≥ 80% and <80%, respectively) to oral antidiabetic drugs, ACE inhibitors/ARBs, and statins over 2 years. To test for HAB, we estimated pairs of regression models, one set containing variables typically controlled for in conventional claims analysis and a second set with survey-based variables selected to capture HAB effects. We found consistent evidence that controlling for HAB reduces estimated savings in medical costs from better adherence, and likewise, reduces estimates of additional adherence-related drug spending. For ACE inhibitors/ARBs we estimate that controlling for HAB reduced adherence-related medical cost offsets from $6389 to $4920 per person (P<0.05). Estimates of additional adherence-related drug costs were 26% and 14% lower in HAB-controlled models (P < 0.05). These results buttress the economic case for action by health care payers to improve medication adherence among insured persons with chronic disease. However, given the limitations of our research design, further research on larger samples with other disease states is clearly warranted.

Beyond the antigen receptor: editing the genome of T-cells for cancer adoptive cellular therapies

Directory of Open Access Journals (Sweden)

Angharad eLloyd

2013-08-01

Full Text Available Recent early-stage clinical trials evaluating the adoptive transfer of patient CD8+ T-cells re-directed with antigen receptors recognising tumours have shown very encouraging results. These reports provide strong support for further development of the therapeutic concept as a curative cancer treatment. In this respect combining the adoptive transfer of tumour-specific T-cells with therapies that increase their anti-tumour capacity is viewed as a promising strategy to improve treatment outcome. The ex-vivo genetic engineering step that underlies T-cell re-direction offers a unique angle to combine antigen receptor delivery with the targeting of cell intrinsic pathways that restrict T-cell effector functions. Recent progress in genome editing technologies such as protein- and RNA-guided endonucleases raise the possibility of disrupting gene expression in T-cells in order to enhance effector functions or to bypass tumour immune suppression. This approach would avoid the systemic administration of compounds that disrupt immune homeostasis, potentially avoiding autoimmune adverse effects, and could improve the efficacy of T-cell based adoptive therapies.

Adherence of Helicobacter pylori to the Gastric Mucosa

Full Text Available Bacterial adhesion to the intestinal epithelium is a critical initial step in the pathogenesis of many enteric diseases. Helicobacter pylori is a duodenal pathogen that adheres to the gastric epithelium and causes gastritis and peptic ulceration. The mechanism by which H pylori causes disease has not yet been elucidated but adherence to the gastric mucosa is thought to be an important virulence determinant of the organism. What is known about adherence of H pylori to the gastric mucosa is summarized. Topics discussed are the mechanism of H pylori adherence; in vitro and in vivo models of H pylori infection; and adherence and potential adhesins and receptors for H pylori.

Health behavior change: can genomics improve behavioral adherence?

2012-03-01

The National Human Genome Research Institute recommends pursuing "genomic information to improve behavior change interventions" as part of its strategic vision for genomics. The limited effectiveness of current behavior change strategies may be explained, in part, by their insensitivity to individual variation in adherence responses. The first step in evaluating whether genomics can inform customization of behavioral recommendations is evidence reviews to identify adherence macrophenotypes common across behaviors and individuals that have genetic underpinnings. Conceptual models of how biological, psychological, and environmental factors influence adherence also are needed. Researchers could routinely collect biospecimens and standardized adherence measurements of intervention participants to enable understanding of genetic and environmental influences on adherence, to guide intervention customization and prospective comparative effectiveness studies.

In the evidence-to-practice pathway, guidelines are developed to provide a practical summary of evidence and stimulate change. However, when guidelines are used in practice, adherence to the recommendations in guidelines is limited, and adaptations are common. Thus, we need more detailed knowledge about adherence and adaptations when guidelines are used in practice to understand the end of the evidence-to-practice pathway. Subsequently, the aim is to examine adherence to and adaptations of recommendations in the Swedish National Guidelines for Methods of Preventing Disease. A questionnaire was sent to healthcare professionals and managers in Stockholm between January and March 2014. Adherence to the recommendations was compared between practice settings, and the frequency of different adaptations and reasons for adaptations was analysed. Partial adherence to the guidelines was found. The adherence was significantly greater within primary care than at the hospitals (P guidelines are used in practice. Work with lifestyle habits was partially done in accordance with the guidelines. Lack of time and lack of resources were not the most common reasons for adaptations. Rather, the findings suggest that when patient needs and capabilities contrast with guideline recommendations, patient needs trump adherence to guidelines. © 2017 John Wiley & Sons, Ltd.

2015-12-01

Many Canadian school jurisdictions have developed nutrition policies to promote health and improve the nutritional status of children, but research is needed to clarify adherence, guide practice-related decisions, and move policy action forward. The purpose of this research was to evaluate policy adherence with a review of online lunch menus of elementary schools in Nova Scotia (NS) while also providing transferable evidence for other jurisdictions. School menus in NS were scanned and a list of commonly offered items were categorized, according to minimum, moderate, or maximum nutrition categories in the NS policy. The results of the menu review showed variability in policy adherence that depended on food preparation practices by schools. Although further research is needed to clarify preparation practices, the previously reported challenges of healthy food preparations (e.g., cost, social norms) suggest that many schools in NS are likely not able to use these healthy preparations, signifying potential noncompliance to the policy. Leadership and partnerships are needed among researchers, policy makers, and nutrition practitioners to address the complexity of issues related to food marketing and social norms that influence school food environments to inspire a culture where healthy and nutritious food is available and accessible to children.

Adherence to treatment is a complex and poorly understood phenomenon. This study investigates the relationship between older depressed patients' adherence to antidepressants and their beliefs about and knowledge of the medication. Assessment was undertaken of 108 outpatients over the age of 55 years diagnosed with depressive disorder and treated for at least four weeks with antidepressants. Adherence was assessed using two self-report measures: the Medication Adherence Rating Scale (MARS) and a Global Adherence Measure (GAM). Potential predictors of adherence investigated included sociodemographic, medication and illness variables. In addition, 33 carers were interviewed regarding general medication beliefs. 56% of patients reported 80% or higher adherence on the GAM. Sociodemographic variables were not associated with adherence on the MARS. Specific beliefs about medicines, such as "my health depends on antidepressants" (necessity) and being less worried about becoming dependant on antidepressants (concern) were highly correlated with adherence. General beliefs about medicines causing harm or being overprescribed, experiencing medication side-effects and severity of depression also correlated with poor adherence. Linear regression with the MARS as the dependent variable explained 44.3% of the variance and showed adherence to be higher in subjects with healthy specific beliefs who received more information about antidepressants and worse with depression severity and autonomic side-effects. Our findings strongly support a role for specific beliefs about medicines in adherence. Challenging patients' beliefs, providing information about treatment and discussing side-effects could improve adherence. Poor response to treatment and medication side-effects can indicate poor adherence and should be considered before switching medications.

In the present study, medication adherence and factors affecting adherence were examined in patients taking oral anticancer agents. In June 2013, 172 outpatients who had been prescribed oral anticancer agents by Ogaki Municipal Hospital (Ogaki, Gifu, Japan) completed a questionnaire survey, with answers rated on a five-point Likert scale. The factors that affect medication adherence were evaluated using a customer satisfaction (CS) analysis. For patients with good and insufficient adherence to medication, the median ages were 66 years (range, 21-85 years) and 73 years (range, 30-90 years), respectively (P=0.0004), while the median dosing time was 131 days (range, 3-3,585 days) and 219 days (24-3,465 days), respectively (P=0.0447). In 36.0% (62 out of 172) of the cases, there was insufficient medication adherence; 64.5% of those cases (40 out of 62) showed good medication compliance (4-5 point rating score). However, these patients did not fully understand the effects or side-effects of the drugs, giving a score of three points or less. The percentage of patients with good medication compliance was 87.2% (150 out of 172). Through the CS analysis, three items, the interest in the drug, the desire to consult about the drug and the condition of the patient, were extracted as items for improvement. Overall, the medication compliance of the patients taking the oral anticancer agents was good, but the medication adherence was insufficient. To improve medication adherence, a better understanding of the effectiveness and necessity of drugs and their side-effects is required. In addition, the interest of patients in their medication should be encouraged and intervention should be tailored to the condition of the patient. These steps should lead to improved medication adherence.

As the problem of patient non-adherence persists and a solution appears hard to be found, it continues to be important to look for new ways to further the issue. We recently conducted a meta-review of adherence intervention studies which yielded a preliminary agenda for future research, practice and theory development in patient adherence. The objective of the present project was to find out to what extent adherence experts consider this agenda relevant and feasible. The thirty-five corresponding authors of the review studies included in the meta-review were invited to join the International Expert Forum on Patient Adherence and to participate in a four-week web-based focus group discussion. The discussion was triggered by the points on the preliminary agenda presented as propositions to which forum members could react. Two researchers analysed the transcripts and selected relevant phrases. Twenty adherence experts participated. Various ideas and viewpoints were raised. After the closure of the web-site, the expert forum was asked to authorize the synthesis of the discussion, to list the propositions in order of priority and to answer a few questions on the use of the web-based focus group as a tool to obtain expert opinions. Their ranking showed that the development of simple interventions is the most promising step to take in fostering patient adherence, preferably within a multidisciplinary setting of medical, pharmaceutical, social and technical science and, not in the least, by incorporating patients' perspectives. For enhancing adherence, the development of simple interventions originating from a multidisciplinary perspective including patients' input, appears most promising. Disclosing patients' perspectives requires open communication about patients' expectations, needs and experiences in taking medication and about what might help them to become and remain adherent.

Phosphate control is a crucial treatment goal in end-stage renal disease, but poor patient adherence to phosphate binder therapy remains a challenge. This study aimed to estimate the extent of phosphate binder adherence in hemodialysis patients and to identify potential determinants. Phosphate binder adherence was measured blindly in 135 hemodialysis patients for 2 months using the medication event monitoring system. Patient data, gathered at inclusion through medical records, ad hoc questionnaires and the short form (SF)-36 health survey, included: (1) demographics, (2) perceived side-effects, belief in benefit, self-reported adherence to the therapy, (3) knowledge about phosphate binder therapy, (4) social support, and (5) quality of life (SF-36). Phosphatemia data was collected from charts. 'Being adherent' was defined as missing adherent' as missing adherent. Over the entire 8-week period, 22 % of patients were totally adherent. Mean phosphatemia levels were 0.55 mg/dl lower in adherent than nonadherent patients (4.76 vs. 5.31 mg/dl). Determinants for being totally adherent were living with a partner, higher social support (both were interrelated) and higher physical quality of life. Experiencing intake-related inconvenience negatively affected adherence. The social support and quality of life physical score explained 26 % of the variance in adherence. Phosphate binder nonadherence remains a major problem. Interventions should aim, at least, to improve social support. With few associated factors found and yet low adherence, an individualized approach seems indicated.

This article is a report of the development and testing of the hypothetical model that illustrates relationships between treatment adherence and its psychosocial influencing factors and to elucidate the direct and indirect (mediating) effects of factors on treatment adherence. Poor adherence has been consistently reported in haemodialysis patients. Much research has showed various influencing factors of adherence, but these studies have failed to identify consistent influencing factors. This study was performed using a non-experimental, cross-sectional design. The study subjects were 150 end-stage renal failure patients on haemodialysis at a university hospital located in Incheon, South Korea. Data were collected over 10 months (June 2010-April 2011). The hypothetical model provided a good fit with data. Haemodialysis-related knowledge, perceived barrier to adherence, self-efficacy on adherence, and healthcare provider support had significant effects on adherence. Self-efficacy was found to mediate barrier-adherence and family support-adherence relationships. Self-efficacy in combination with barrier, family support, and healthcare provider support was found to mediate the depression-adherence relationship. Strategies aimed at the development of successful adherence interventions should focus on reducing perceived barriers and enhancing self-efficacy and knowledge. It can be suggested that efforts to improve the healthcare provider-patient relationship would enhance adherence. In depressive patients, strategies that promote self-efficacy and the support of family or healthcare providers could diminish the negative impact of depression on adherence. © 2013 Blackwell Publishing Ltd.

We conducted a randomized trial to test an intervention aimed at increasing adherence to antiretroviral therapy (ART) among HIV-positive, ART-naïve patients in Salvador, Brazil. Participants (N = 107) were randomized to either educational workshops based on the information-motivation-behavioral skills model (n = 52) or a control video session (n = 55). Changes in self-reported ART adherence, viral load, CD4 cell counts and ART pharmacy records were measured periodically over 12 months. After 3-6 months, ART adherence (> or = 95%) was 77.8% in the workshop group and 85.7% in video group (as treated) and 53.8% and 65.5%, respectively, using intention-to-treat (ITT) analysis (both P > 0.05) At 9-12 months, ART adherence decreased to 73.7% in the workshop group and 79.1% in the video group (as treated) and 53.8% and 61.8% using ITT, respectively. No differences were found in self-reported adherence, viral load or pharmacy records between groups. We found that the educational workshop intervention does not increase adherence to ART.

We aimed to develop an in-depth understanding about factors that influence cardiac medication adherence among South Asian, Chinese, and European White cardiac patients. Sixty-four patients were purposively sampled from an ongoing study cohort. Interviews were audio-recorded and transcribed for analyses. Physicians' culturally sensitive communication and patients' motivation to live a symptom-free and longer life enhanced adherence. European Whites were motivated to enhance personal well-being and enjoy family life. South Asians' medication adherence was influenced by the desire to fulfill the will of God and family responsibilities. The Chinese were motivated to avoid pain, illness, and death, and to obey a health care provider. The South Asians and Chinese wanted to ultimately reduce medication use. Previous positive experiences, family support, and establishing a routine also influenced medication adherence. Deterrents to adherence were essentially the reverse of the motivators/facilitators. This analysis represents an essential first step forward in developing ethno-culturally tailored interventions to optimize adherence.

People transfer-sinequanon for nuclear technology transfer

International Nuclear Information System (INIS)

Ahmed, M.

1977-01-01

The main obstacles facing the developing countries which wish to adopt sophisticated nuclear technology can be the following: lack of trained personnel, lack of entrepreneurs and capital, and bureaucracy. Of these the greatest problem is undoubtedly the lack of trained manpower. Urgently required skilled manpower may be obtained through training of selected persons in foreign countries on a crash program of nuclear energy. Exchange of expertise can also take place among the developing countries themselves. Another problem particularly peculiar to the poor developing countries is the lack of entrepreneurs and capital. It therefore becomes necessary to attract entrepreneurs from abroad with all the benefit of managerial know-how and capital transfer that it entails. Exchange of scientist, teachers, managerial and administrative personnel between the developed and developing countries and also among the developing countries themselves is therefore essential for an effective transfer of nuclear technology

Kline, Susan L; Chatterjee, Karishma; Karel, Amanda I

2009-01-01

Given that the public uses the media to learn about adoption as a family form, this study analyzes U.S. television news coverage of adoption between 2001 and 2005 (N = 309 stories), to identify the types of news events covered about adoption. A majority of news stories covered fraud, crime, legal disputes, and negative international adoption cases. Adoptees as defective or unhealthy were depicted more in negative news event stories, birth parents appeared less overall, and adoptive parents were most likely to have healthy depictions in positively oriented adoption experience, big family, and reunion stories. Although three quarters of the stories used primary adoption participants as news sources, one-third of the negative event stories did not contain healthy depictions of adoption participants. The authors discuss ways journalists and researchers might improve adoption news coverage.

Adopters and non-adopters of wood pellet heating in Norwegian households

International Nuclear Information System (INIS)

Sopha, Bertha Maya; Hertwich, Edgar G.; Kloeckner, Christian A.

2011-01-01

The aim of the present paper is to understand the differences between adopters and non-adopters of wood pellet heating in Norwegian households by comparing the two groups with regard to key points of adoption. A mail survey of 669 adopters and 291 non-adopters of wood pellet heating was conducted in 2008. Results indicate that there are significant differences between groups with respect to socio-demographic factors, decision-related factors, heating systems adopted and reasons for shifting heating systems. The results also indicate that the adopter group shows characteristics of early adopters, whereas the non-adopter group has characteristics of late adopters. The results for levels of income and education contradict what would be predicted from theory, however. Both groups show no significant difference with respect to values, but the perception of which heating system is the most environmentally friendly differs significantly. The top three reasons cited by the adopter group for installing wood pellet heating are getting an environmentally friendly heating system, low operation costs and an anticipated increase in electricity prices. According to the non-adopter group, the main barriers to adoption are high installation costs, followed by the difficulties of refitting the house for wood pellet heating. A higher subsidy (i.e., an average of 64% of the total installation cost) rather than the current subsidy of up to 20% was required by the non-adopter group to switch to wood pellet heating.

Introduction: Autologous or allogeneic transfer of tumor-infiltrating T-lymphocytes is a promising treatment for metastatic cancers, but a major concern is the difficulty in evaluating cell trafficking and distribution in adoptive cell therapy. This study presents a method of tracking transfusion of T-lymphoblasts in a porcine model by {sup 18}F-2-fluoro-2-deoxy-D-glucose ([{sup 18}F]FDG) and positron emission tomography. Methods: T-lymphoblasts were labeled with the positron-emitting tracer [{sup 18}F]FDG through incubation. The T-lymphoblasts were administered into the bloodstream, and the distribution was followed by positron emission tomography for 120 min. The cells were administered either intravenously into the internal jugular vein (n=5) or intraarterially into the ascending aorta (n=1). Two of the pigs given intravenous administration were pretreated with low-molecular-weight dextran sulphate. Results: The cellular kinetics and distribution were readily quantifiable for up to 120 min. High (78.6% of the administered cells) heterogeneous pulmonary uptake was found after completed intravenous transfusion. The pulmonary uptake was decreased either by preincubating and coadministrating the T-lymphoblasts with low-molecular-weight dextran sulphate or by administrating them intraarterially. Conclusions: The present work shows the feasibility of quantitatively monitoring and evaluating cell trafficking and distribution following administration of [{sup 18}F]FDG-labeled T-lymphoblasts. The protocol can potentially be transferred to the clinical setting with few modifications.

Age at placement, adoption experience and adult adopted people's contact with their adoptive and birth mothers: an attachment perspective.

Howe, D

2001-09-01

Adoption holds particular interest for attachment researchers. Although children adopted as babies experience almost continuous care by their adoptive parents, older placed children experience at least one major change of caregiver when they join their adoptive family. Moreover, in the majority of cases, older placed children have generally suffered a pre-adoption history of abuse, neglect and/or rejection. It is now being recognized that older placed children's attachment histories and internal working models (IWMs) established in relationship with their initial carers remain active in relationship with their new carers. Transactional models have helped both researchers and practitioners to understand the dynamics of parent-child relationships in cases where insecure children with histories of neglect, abuse and rejection find themselves in new caregiving environments. The present study examines the childhood experiences of adult adopted people and their current levels of contact with their adoptive mothers, and in cases where people had searched for and found a birth relative, current levels of contact with their birth mother. Although no information was collected on the adopted adult's pre-placement history, age at placement was used as a proxy measure to examine whether older placed children reported different adoption experiences and what their current levels of contact were with their adoptive and birth mothers. The findings show that age at placement was associated with adopted people's reported experiences of being adopted and current rates of contact with their adoptive and birth mothers, with those placed at older ages most likely to report that they (1) did not feel they belonged in their adoptive families while growing up, (2) did not feel loved by their adoptive mother, (3) were least likely to remain in high-frequency contact with their adoptive mother, and (4) were least likely to remain in high-frequency contact with their birth mother.

HIV-positive persons who do not maintain consistently high levels of adherence to often complex and toxic highly active antiretroviral therapy (HAART) regimens may experience therapeutic failure and deterioration of health status and may develop multidrug-resistant HIV that can be transmitted to uninfected others. The current analysis conceptualizes social and psychological determinants of adherence to HAART among HIV-positive individuals. The authors propose an information-motivation-behavioral skills (IMB) model of HAART adherence that assumes that adherence-related information, motivation, and behavioral skills are fundamental determinants of adherence to HAART. According to the model, adherence-related information and motivation work through adherence-related behavioral skills to affect adherence to HAART. Empirical support for the IMB model of adherence is presented, and its application in adherence-promotion intervention efforts is discussed.

Medication non-adherence is common and the physicians awareness of it may be an important factor in clinical decision making. Few sources of data on physician awareness of medication non-adherence are available. We have designed an algorithm to identify documentation of medication non-adherence in the text of physician notes. The algorithm recognizes eight semantic classes of documentation of medication non-adherence. We evaluated the algorithm against manual ratings of 200 randomly selected notes of hypertensive patients. The algorithm detected 89% of the notes with documented medication non-adherence with specificity of 84.7% and positive predictive value of 80.2%. In a larger dataset of 1,000 documents, notes that documented medication non-adherence were more likely to report significantly elevated systolic (15.3% vs. 9.0%; p = 0.002) and diastolic (4.1% vs. 1.9%; p = 0.03) blood pressure. This novel clinically validated tool expands the range of information on medication non-adherence available to researchers.

Full Text Available The aim was to assess inflammatory markers among adults and adolescents in relation to the adherence to the Mediterranean diet. A random sample (219 males and 379 females of the Balearic Islands population (12–65 years was anthropometrically measured and provided a blood sample to determine biomarkers of inflammation. Dietary habits were assessed and the adherence to the Mediterranean dietary pattern calculated. The prevalence of metabolic syndrome increased with age in both sexes. The adherence to the Mediterranean diet in adolescent males was 51.3% and 45.7% in adults, whereas in females 53.1% and 44.3%, respectively. In males, higher adherence to the Mediterranean diet was associated with higher levels of adiponectin and lower levels of leptin, tumor necrosis factor alpha (TNF-α, plasminogen activator inhibitor 1 (PAI-1 and high-sensitivity C-reactive protein (hs-CRP in adults, but not in young subjects. In females, higher adherence was associated with lower levels of leptin in the young group, PAI-1 in adults and hs-CRP in both groups. With increasing age in both sexes, metabolic syndrome increases, but the adherence to the Mediterranean diet decreases. Low adherence to the Mediterranean dietary pattern (MDP is directly associated with a worse profile of plasmatic inflammation markers.

Adherence to treatment in patients on hemodialysis is not a simple process. Strategies to promote adherence will meet the need for improvements in the process of orientation concerning the disease and its pharmacological treatment. To identify compliance with pharmacological treatment of patients on hemodialysis and the main factors related to it we used the Adherence Scale. Observational, descriptive and cross-sectional study. Interviews were conducted to collect socioeconomic, pharmacological data, as well as those regarding self-reported adherence to drug. Out of the 65 participants, 55.4% showed non-compliance. The mean number of drugs used was 4.1 ± 2.5 (self-report) and 6.2 ± 3.0 (prescription). Statistical analysis showed significant differences concerning compliance at different ages (> 60 years are more adherent). A significant proportion of patients have difficulty to comply with treatment and the main factor was forgetfulness. Regarding age, elderly patients are more adherent to treatment. The low level of knowledge about the used drugs may be one of the reasons for the lack of adherence, and the patient's orientation process by a team of multiprofessionals involved in assisting is a strategy to promote adherence.

Adherence of Moraxella bovis to cell cultures of bovine origin.

Annuar, B O; Wilcox, G E

1985-09-01

The adherence of five strains of Moraxella bovis to cell cultures was investigated. M bovis adhered to cultures of bovine corneal epithelial and Madin-Darby bovine kidney cells but not to cell types of non-bovine origin. Both piliated and unpiliated strains adhered but piliated strains adhered to a greater extent than unpiliated strains. Antiserum against pili of one strain inhibited adherence of piliated strains but caused only slight inhibition of adherence to the unpiliated strains. Treatment of bacteria with magnesium chloride caused detachment of pili from the bacterial cell and markedly inhibited adherence of piliated strains but caused only slight inhibition of adherence by the unpiliated strains. The results suggested that adhesion of piliated strains to cell cultures was mediated via pili but that adhesins other than pili may be involved in the attachment of unpiliated strains of M bovis to cells.

Expansion of Human Tregs from Cryopreserved Umbilical Cord Blood for GMP-Compliant Autologous Adoptive Cell Transfer Therapy

Full Text Available Umbilical cord blood is a traditional and convenient source of cells for hematopoietic stem cell transplantation. Thymic regulatory T cells (Tregs are also present in cord blood, and there is growing interest in the use of autologous Tregs to provide a low-risk, fully human leukocyte antigen (HLA-matched cell product for treating autoimmune diseases, such as type 1 diabetes. Here, we describe a good manufacturing practice (GMP-compatible Treg expansion protocol using fluorescence-activated cell sorting, resulting in a mean 2,092-fold expansion of Tregs over a 16-day culture for a median yield of 1.26 × 109 Tregs from single-donor cryopreserved units. The resulting Tregs passed prior clinical trial release criteria for Treg purity and sterility, including additional rigorous assessments of FOXP3 and Helios expression and epigenetic analysis of the FOXP3 Treg-specific demethylated region (TSDR. Compared with expanded adult peripheral blood Tregs, expanded cord blood Tregs remained more naive, as assessed by continued expression of CD45RA, produced reduced IFN-γ following activation, and effectively inhibited responder T cell proliferation. Immunosequencing of the T cell receptor revealed a remarkably diverse receptor repertoire within cord blood Tregs that was maintained following in vitro expansion. These data support the feasibility of generating GMP-compliant Tregs from cord blood for adoptive cell transfer therapies and highlight potential advantages in terms of safety, phenotypic stability, autoantigen specificity, and tissue distribution.

Tumor-induced immune defects can weaken host immune response and permit tumor cell growth. In a systemic model of murine acute myeloid leukemia (AML), tumor progression resulted in increased regulatory T cells (Treg) and elevation of program death-1 (PD-1) expression on CD8(+) cytotoxic T cells (CTLs) at the tumor site. PD-1 knockout mice were more resistant to AML despite the presence of similar percentage of Tregs compared with wild type. In vitro, intact Treg suppression of CD8(+) T-cell responses was dependent on PD-1 expression by T cells and Tregs and PD-L1 expression by antigen-presenting cells. In vivo, the function of adoptively transferred AML-reactive CTLs was reduced by AML-associated Tregs. Anti-PD-L1 monoclonal antibody treatment increased the proliferation and function of CTLs at tumor sites, reduced AML tumor burden, and resulted in long-term survivors. Treg depletion followed by PD-1/PD-L1 blockade showed superior efficacy for eradication of established AML. These data demonstrated that interaction between PD-1 and PD-L1 can facilitate Treg-induced suppression of T-effector cells and dampen the antitumor immune response. PD-1/PD-L1 blockade coupled with Treg depletion represents an important new approach that can be readily translated into the clinic to improve the therapeutic efficacy of adoptive AML-reactive CTLs in advanced AML disease.

Although parental socialization styles have been investigated in recent years, little research has been carried out on the issue of parental styles in adoptive families. The aim of this research is to analyse parental styles both from the point of view of the parents and of adopted and non-adopted adolescents, taking as covariables the adolescents' sex and age. The sample was made up of 55 adopted adolescents (20 boys and 35 girls with an age range of 11-17 years) and their 55 adoptive parents, and 402 non-adopted adolescents (200 boys and 202 girls with an age range of 11-17 years), and their 258 parents. Two scales evaluated parental styles: the Affect Scale and the Rules and Demands Scale. The results showed that, both from the point of view of the parents and of the adolescents, adoptive families are more affective, communicative and inductive, and less critical and indulgent than non-adoptive families. No differences were found between adopted and non-adopted adolescents on the Parents' Rigidity Scale.

OBJECTIVE To provide a model that enables health systems and pharmacy benefit managers to provide medications reliably and test for reliability and validity in the analysis of adherence to drug therapy of chronic disease. SUMMARY The quantifiable model described here can be used in conjunction with behavioral designs of drug adherence assessments. The model identifies variables that can be reproduced and expanded across the management of chronic diseases with drug therapy. By creating a reorder point system for reordering medications, the model uses a methodology commonly seen in operations research. The design includes a safety stock of medication and current supply of medication, which increases the likelihood that patients will have a continuous supply of medications, thereby positively affecting adherence by removing barriers. CONCLUSION This method identifies an adherence model that quantifies variables related to recommendations from health care providers; it can assist health care and service delivery systems in making decisions that influence adherence based on the expected order cycle days and the expected daily quantity of medication administered. This model addresses the possession of medication as a barrier to adherence.

CMV-specific CD8 T Cell Differentiation and Localization: Implications for Adoptive Therapies

Directory of Open Access Journals (Sweden)

Corinne J Smith

2016-09-01

Full Text Available Human cytomegalovirus (HCMV is a ubiquitous virus that causes chronic infection, and thus is one of the most common infectious complications of immune suppression. Adoptive transfer of HCMV-specific T cells has emerged as an effective method to reduce the risk for HCMV infection and/or reactivation by restoring immunity in transplant recipients. However, the CMV-specific CD8+ T cell response is comprised of a heterogenous mixture of subsets with distinct functions and localization and it is not clear if current adoptive immunotherapy protocols can reconstitute the full spectrum of CD8+ T cell immunity. The aim of this review is to briefly summarize the role of these T cell subsets in CMV immunity and to describe how current adoptive immunotherapy practices might affect their reconstitution in patients. The bulk of the CMV-specific CD8+ T cell population is made up of terminally differentiated effector T cells with immediate effector function and a short life span. Self-renewing memory T cells within the CMV-specific population retain the capacity to expand and differentiate upon challenge and are important for the long-term persistence of the CD8+ T cell response. Finally mucosal organs, which are frequent sites of CMV reactivation, are primarily inhabited by tissue resident memory T cells, which do not recirculate. Future work on adoptive transfer strategies may need to focus on striking a balance between the formation of these subsets to ensure the development of long lasting and protective immune responses that can access the organs affected by CMV disease.

Loss of KCl and cell shrinkage are hallmarks in apoptosis and has been shown in EATC. However, we find no reduction in cell volume and only a minor loss of K(+) which is accompanied by net uptake of Na(+) following 18 hours cisplatin exposure in ELA. Glutathione and taurine...

Measurement complexity of adherence to medication

Full Text Available Dayani Galato, Fabiana Schuelter-Trevisol, Anna Paula PiovezanMaster Program in Health Sciences, University of Southern Santa Catarina (Unisul Tubarão, Santa Catarina, BrazilAdherence to pharmacologic therapy is a major challenge for the rational use of medicines, particularly when it comes to antiretroviral drugs that require adherence to at least 95% of prescribed doses.1 Studies in this area are always important and contribute to medication adherence understanding, even though there is no reference test for measuring this. Recently, an article was published in this journal that proposes the determination of lamivudine plasma concentration to validate patient self-reported adherence to antiretroviral treatment.2 In that study, serum levels obtained after 3 hours of ingestion of the last dose of the drug were compared with patient reports that were classified into different levels of adherence, based on their recall of missed doses in the previous 7 days.It was hypothesized by the authors that the use of a biological marker for drug adherence was extremely important, given the relevance of the topic. However, we would like to draw attention to some points that may determine the success of the use of similar methods for this purpose. The formation of groups with similar anthropometric characteristics is relevant since the dose of lamivudine may have to be changed, depending, for example, on sex, weight, and age.3 Even information considered important by the authors of that study was not provided. There is a need for greater clarity on the eligibility criteria, especially with regard to the clinical stage of the disease, CD4 counts and viral load, associated diseases, and comorbidity, as well as the evaluation of kidney function and other medications used that can affect lamivudine pharmacokinetics.3View original paper by Minzi and colleagues

Full Text Available This study explores perceptions that affect adherence behaviors among Mexican Americans living with dialysis. In-depth narrative interviews were conducted with 15 Mexican Americans with end-stage renal disease (ESRD living on dialysis, 15 family members, and 6 health care personnel who provided care to them. Four themes emerged: (a positive influences to adherence, (b obstacles to adherence, (c daily activity losses, and (d fears about living with dialysis. From the findings, the perceptions given for non-adherence with the dialysis regimen ranged from denial of the condition, lack of pre-education, to cultural factors. Those given for adherence included prolonged life, family, and hope of getting a transplant. Health care providers were the reminder to adhere. Several cultural factors influenced their adherence perceptions. Strategies to enhance adherence behaviors should focus on knowledge about dialysis, use of the collective efficacy of the family, and the inclusion of cultural values.

Full Text Available In the context in which transfer pricing may represent a mechanism through which multinationals have the possibility to move funds internationally, in order to prevent the base erosion and profit shifting between multinationals, countries over the world have adopted various transfer pricing regulations. Furthermore, some of the countries adopted stricter regulations than others. The objective of our research was to identify the level of strictness for the transfer pricing regulations from the European countries. To achieve this objective, we analyzed the transfer pricing regulations of all European countries and we built a transfer pricing strictness index, based on which we defined 4 categories of countries (where category 1 includes the countries with the least strict transfer pricing regulations and category 4 countries with the strictest regulations. After that, we illustrated how these categories are distributed on the European map. In order to collect the information, we used the transfer pricing guides issued by the Big Four companies for the year 2015. The study`s results show that the strictness of the transfer pricing regulations decreases from the west of Europe to east. Moreover, most of the countries were included in category 2, respectively category 3, meaning that the transfer pricing regulations from the European continent are not so flexible, but in the same time are not so strict.

Recent literature has shown that the good outcome of adoption would mostly depend on the quality of adoptive parenting, which is strongly associated with the security of parental internal working models (IWMs) of attachment. Specifically, attachment states-of-mind of adoptive mothers classified as free and autonomous and without lack of resolution of loss or trauma could represent a good protective factor for adopted children, previously maltreated and neglected. While most research on adoptive families focused on pre-school and school-aged children, the aim of this study was to assess the concordance of IWMs of attachment in adoptive dyads during adolescence. Our pilot-study involved 76 participants: 30 adoptive mothers (mean age = 51.5 ± 4.3), and their 46 late-adopted adolescents (mean age = 13.9 ± 1.6), who were all aged 4-9 years old at time of adoption (mean age = 6.3 ± 1.5). Attachment representations of adopted adolescents were assessed by the Friend and Family Interview (FFI), while adoptive mothers' state-of-mind with respect to attachment was classified by the Adult Attachment Interview (AAI). Adolescents' verbal intelligence was controlled for. Late-adopted adolescents were classified as follows: 67% secure, 26% dismissing, and 7% preoccupied in the FFI, while their adoptive mothers' AAI classifications were 70% free-autonomous, 7% dismissing, and 23% unresolved. We found a significant concordance of 70% (32 dyads) between the secure-insecure FFI and AAI classifications. Specifically adoptive mothers with high coherence of transcript and low unresolved loss tend to have late-adopted children with high secure attachment, even if the adolescents' verbal intelligence made a significant contribution to this prediction. Our results provides an empirical contribution to the literature concerning the concordance of attachment in adoptive dyads, highlighting the beneficial impact of highly coherent states-of-mind of adoptive mothers on the attachment

We aimed to produce motivational posters to support nebulizer adherence by using social marketing involving people with CF in the development of those posters. Methods: The Sheffield CF multidisciplinary team produced preliminary ideas that were elaborated upon with semi-structured interviews among people with CF to explore barriers and facilitators to the use of nebulized therapy. Initial themes and poster designs were refined using an online focus group to finalize the poster designs. Results: People with CF preferred aspirational posters describing what could be achieved through adherence in contrast to posters that highlighted the adverse consequences of nonadherence. A total of 14 posters were produced through this process. Conclusion: People with CF can be engaged to develop promotional material to support adherence, providing a unique perspective differing from that of the CF multidisciplinary team. Further research is needed to evaluate the effectiveness of these posters to support nebulizer adherence.

With the increase in scaling up of antiretroviral therapy (ART), knowledge of the need for adherence to ART is pivotal for successful treatment outcomes. A cross-sectional study was carried out between October and December 2013. We administered theory of planned behaviour (TPB) and adherence questionnaires to 358 women aged 18-49 years, from a rural and urban ART-clinics in southern Malawi. Hierarchical linear regression models were used to predict intentions to adhere to ART. Regression models show that attitude (β=0.47), subjective norm (β=0.31) and perceived behavioural control (β=0.12) explain 55% of the variance in intentions to adhere to ART. The relationship between both food insecurity and perceived side effects with intentions to adhere to ART is mediated by attitude, subjective norm, and perceived behavioural control. Household (r=0.20) and individual (r=0.21) food insecurity were positively and significantly correlated with perceived behavioural control. Household food insecurity had a negative correlation with perceived side effects (r=-0.11). Perceived side effects were positively correlated with attitude (r=0.25). There was no statistically significant relationship between intentions to adhere to ART in the future and one month self-report of past month adherence. These interactions suggest that attitude predicted adherence only when food insecurity is high or perception of side effects is strong. This study shows that modification might be needed when using TPB constructs in resource constraint environments. Significance for public healthThe knowledge of the rates of adherence to antiretroviral therapy (ART) could be used to evaluate planning and project, which could lead to better outcomes predicted by treatment efficacy data. In addition, knowledge of adherence behaviour could help the development of interventions focusing on collaboration between healthcare providers and Malawian government to provide food support for patients on ART.

Sixty children and adolescents in end-stage renal failure who were undergoing either haemodialysis or continuous ambulatory peritoneal dialysis at one of five United Kingdom dialysis centres were assessed on psychosocial adjustment and adherence to their fluid intake, diet and medication regimes. Parental adjustment was also measured and data on sociodemographic and treatment history variables collected. A structured family interview and standardised questionnaire measures of anxiety, depression and behavioural disturbance were used. Multiple measures of treatment adherence were obtained, utilising children's and parents' self-reports, weight gain between dialysis, blood pressure, serum potassium level, blood urea level, dietitians' surveys and consultants' ratings. Correlational analyses showed that low treatment adherence was associated with poor adjustment to diagnosis and dialysis by children and parents (P adherence than younger children, P dialysis (P treatment of this group of children. Future research should develop and evaluate psychosocial interventions aimed at improving treatment adherence.

Identify attitudes and behaviors that evidence and characterize family adherence to treatment in patients with severe mental disorder. Qualitative descriptive, from an interpretative social approach. Chia, Colombia, with professionals in the psychiatric and geriatric settings. Twelve professionals in psychiatry, nursing and psychology, with experience in care of patients with serious mental disorder and their families. Intentional sampling. Twelve semi-structured interviews were carried out. The analysis strategy was made from the procedures of constant comparison and open coding of the grounded theory. As validation strategies, triangulation was done between researchers and methods, as interviews and results survey. Two categories of family adherence were defined: family and treatment (treatment cooperation, knowledge about the disease and attention to the disease evolution), and family attitudes towards the patient (patient's care, patient's promotion of autonomy, and affective attachment with the patient). A third category showed aspects that diminished family adherence, such as lack or distortion of information regarding mental disorder, or family and patient endurance attitudes. Participants agree about the relevance of the construct named «family adherence», which describes the behaviors and attitudes of the family regarding the treatment of patients with severe mental disorder. Family adherence can be seen as active participation behavior, but also as a process of strengthening relationships, which can reduce the burden and suffering on family members, caregivers and patients.

Although antiretroviral therapy has increased the survival of HIV-positive patients, traditional approaches to improving medication adherence have failed consistently. Acknowledging the role of communication in health behavior, we conducted a qualitative study to learn about patients' HIV treatment adherence experiences and to identify which communication strategies might influence adherence. Findings indicate that five constructs--cultural beliefs/language, stigma, cues to action, self-efficacy, and mood state--are potentially modifiable by improved communication. Results will be used to create a direct marketing campaign targeted to HIV-infected patients. Copyright © Taylor & Francis Group, LLC

It is challenging for dialysis patients to maintain adherence to their medical regimen, and symptoms of depression are prevalent among them. Limited data is available about adherence and depression among patients receiving peritoneal dialysis (PD). This study aimed to examine the rates of treatment non-adherence and depression in PD patients. A total of 20 PD patients (response rate 71.4%; mean age 64.4 ± 11.6 years) were assessed using the Beliefs about Medicines Questionnaire, Self Efficacy for Managing Chronic Disease Scale, Hospital Anxiety and Depression Scale (HAD) and Kidney Disease Quality of Life-Short Form. A self-reported adherence (PD exchanges, medication and diet) scale developed for the study was also included. Medical information (e.g. most recent biochemistry results) was obtained from chart review. The mean self-reported scores indicated an overall high level of adherence, although a significant proportion of patients were non-adherent. Among the latter, 20% of patients were non-adherent to medication and 26% to diet due to forgetfulness, while 15% and 26% of patients admitted to deliberate non-adherence to medication and diet, respectively. Treatment modality, employment, self-care status and self-efficacy were associated with overall adherence. Using a cutoff point of 8 for HAD depression and anxiety subscales, 40% of patients were found to be depressed and 30% had symptoms of anxiety. This is the first study to document treatment adherence and depression among PD patients in Singapore. Findings of high prevalence of depression and anxiety, and reports of poor adherence warrant development of intervention programmes.

Poor adherence to immunosuppressive medications is a major cause of premature graft loss among children and young adults. Multicomponent interventions have shown promise but have not been fully evaluated. Unblinded parallel-arm randomized trial to assess the efficacy of a clinic-based adherence-promoting intervention. Prevalent kidney transplant recipients 11 to 24 years of age and 3 or more months posttransplantation at 8 kidney transplantation centers in Canada and the United States (February 2012 to May 2016) were included. Adherence was electronically monitored in all participants during a 3-month run-in, followed by a 12-month intervention. Participants assigned to the TAKE-IT intervention could choose to receive text message, e-mail, and/or visual cue dose reminders and met with a coach at 3-month intervals when adherence data from the prior 3 months were reviewed with the participant. "Action-Focused Problem Solving" was used to address adherence barriers selected as important by the participant. Participants assigned to the control group met with coaches at 3-month intervals but received no feedback about adherence data. The primary outcomes were electronically measured "taking" adherence (the proportion of prescribed doses of immunosuppressive medications taken) and "timing" adherence (the proportion of doses of immunosuppressive medications taken between 1 hour before and 2 hours after the prescribed time of administration) on each day of observation. Secondary outcomes included the standard deviation of tacrolimus trough concentrations, self-reported adherence, acute rejection, and graft failure. 81 patients were assigned to intervention (median age, 15.5 years; 57% male) and 88 to the control group (median age, 15.8 years; 61% male). Electronic adherence data were available for 64 intervention and 74 control participants. Participants in the intervention group had significantly greater odds of taking prescribed medications (OR, 1.66; 95% CI, 1

Fuel Transfer System facilitates loading of new fuel into Fuelling Machine, receipt of spent fuel from Fuelling Machine and its further transportation to Storage Bay. To overcome the limitations of transferring a pair of bundles in the single tube Airlock and Transfer Arm in RAPS-1 and 2/MAPS, a new concept of six tube Transfer Magazine was introduced in NAPS. This resulted in simultaneous loading of new fuel from Transfer Magazine into the Fuelling Machine and unloading of spent fuel from the Fuelling Machine through the exchange mode. It further facilitated the parallel/simultaneous operation of refuelling by Fuelling Machines on the reactor and transferring of spent fuel bundles from the Transfer Magazine to the bay. This new design of Fuel Transfer System was adopted for all standardised 220 MWe PHWRs. Based on the experience gained in 220 MWe PHWRs in the area of operation and maintenance, a number of improvements have been carried out over the years. These aspects have been further strengthened and refined in the Fuel Transfer System of 540 MWe units. The operating experience of the system indicates that the presence of heavy water in the Transfer Magazine poses limitations in its maintenance in the Fuel Transfer room. Further, Surveillance and maintenance of large number of under water equipment and associated valves, rams and underwater sensors is putting extra burden on the O and M efforts. A new concept of mobile light water filled Transfer Machine has been evolved for proposed 700 MWe PHWR units to simplify Fuel Transfer System. This has been made possible by adopting snout level control in the Fuelling Machine, elimination of Shuttle Transport System and locating the Storage Bay adjacent to the Reactor Building. This paper describes the evolution of Fuel Transfer System concepts and various improvements based on the experience gained in the operation and maintenance of the system. (author)

The aim of this case-control study was to compare Mediterranean diet (MD) adherence and anthropometry between Greek diaspora adolescents living in Istanbul and Greek adolescents, inhabitants of Athens. A total of 206 adolescents (103 from each site), aged 10.0-19.0 years old, all of Greek origin, were recruited from schools in Athens and minority schools in Istanbul, for the present case-control study. Participants at each site were age and sex-matched. Anthropometric measurements were performed, and diet adherence was assessed with the KIDMED score. Breakfast skipping, decreased dairy and increased commercially baked good/pastries consumption for breakfast, fast-food intake and consumption of several sweets each day was more prevalent in Istanbul, but, on the other hand, students from Athens reported eating fewer fruit, vegetables and nuts. The adoption of unhealthy eating habits in each site was counterbalanced by a more 'healthy' dietary element, resulting in an overall similar MD adherence between both sites. Additionally, although weight status was indifferent between the two cities, higher rates of abdominal obesity were recorded in Istanbul, when the weight-to-height ratio was used for diagnosis. Differences in several domains of the KIDMED score were recorded among cities, possibly as results of food availability and prices. However, MD adherence and weight status appeared similar, indicating that the dietary transition and acculturation experienced by the remnants is actually very slow and minimal during the 93 years since population exchange.

Combining antiangiogenic therapy with adoptive cell immunotherapy exerts better antitumor effects in non-small cell lung cancer models.

Directory of Open Access Journals (Sweden)

Shujing Shi

Full Text Available INTRODUCTION: Cytokine-induced killer cells (CIK cells are a heterogeneous subset of ex-vivo expanded T lymphocytes which are characterized with a MHC-unrestricted tumor-killing activity and a mixed T-NK phenotype. Adoptive CIK cells transfer, one of the adoptive immunotherapy represents a promising nontoxic anticancer therapy. However, in clinical studies, the therapeutic activity of adoptive CIK cells transfer is not as efficient as anticipated. Possible explanations are that abnormal tumor vasculature and hypoxic tumor microenvironment could impede the infiltration and efficacy of lymphocytes. We hypothesized that antiangiogenesis therapy could improve the antitumor activity of CIK cells by normalizing tumor vasculature and modulating hypoxic tumor microenvironment. METHODS: We combined recombinant human endostatin (rh-endostatin and CIK cells in the treatment of lung carcinoma murine models. Intravital microscopy, dynamic contrast enhanced magnetic resonance imaging, immunohistochemistry, and flow cytometry were used to investigate the tumor vasculature and hypoxic microenvironment as well as the infiltration of immune cells. RESULTS: Our results indicated that rh-endostatin synergized with adoptive CIK cells transfer to inhibit the growth of lung carcinoma. We found that rh-endostatin normalized tumor vasculature and reduced hypoxic area in the tumor microenvironment. Hypoxia significantly inhibited the proliferation, cytotoxicity and migration of CIK cells in vitro and impeded the homing of CIK cells into tumor parenchyma ex vivo. Furthermore, we found that treatment with rh-endostatin significantly increased the homing of CIK cells and decreased the accumulation of suppressive immune cells in the tumor tissue. In addition, combination therapy produced higher level of tumor-infiltration lymphocytes compared with other treatments. CONCLUSIONS: Our results demonstrate that rh-endostatin improves the therapeutic effect of adoptive CIK cells

Chronic insomnia is a significant public health problem worldwide, and insomnia has considerable personal and social costs associated with serious health conditions, greater healthcare utilization, work absenteeism, and motor-vehicle accidents. Cognitive behavioral therapy for insomnia (CBTI) is an efficacious treatment, yet attrition and suboptimal adherence may diminish its impact. Despite the increasing use of CBTI, surprisingly little attention has been devoted to understanding the role of adherence. This review describes a comprehensive literature search of adherence to CBTI. The search revealed 15 studies that evaluated adherence to CBTI in adults using valid and reliable measures of sleep, and measure of adherence other than study withdrawals. The primary purposes of this review were to 1) synthesize current study characteristics, methodology, adherence rates, contributing factors, and impact on outcomes, 2) discuss measurement issues, and 3) identify future practice and research directions that may lead to improved outcomes. Strong patterns and inconsistencies were identified among the studies, which complicate an evaluation of the role of adherence as a factor and outcome of CBTI success. The importance of standardized adherence and outcome measures is discussed. In light of the importance of adherence to behavior change, this systematic review may better inform future intervention efforts. Copyright © 2013 Elsevier Ltd. All rights reserved.

Summary Poor adherence to continuous positive airway pressure (CPAP) treatment is associated with substantial health care costs, morbidity and mortality, and has been a leading obstacle in the effective management of obstructive sleep apnea (OSA). Successful interventions to improve CPAP adherence may ultimately include a variety of components. For patients living with spouses (refers to all domestic partners), the spouse will likely be an integral component to any successful intervention. Developing understanding of the role of spouses in adherence to CPAP has been identified to be a critical research need. This review expands the investigation of CPAP adherence to a broader context, from an exclusive focus on individual patients to a dyadic perspective encompassing both patients and their spouses. A conceptual framework based on social support and social control theories is proposed to understand spousal involvement in CPAP adherence. Methodologies for future investigations are discussed, along with implications for developing interventions that engage both patients and their spouses to improve CPAP use. PMID:24906222

This study examined the attachment patterns of late-adopted children (aged 4-7) and their adoptive mothers during the first 7- to 8-month period after adoption and aimed to evaluate the effect of adoptive mothers' attachment security on the revision of the attachment patterns of their late-adopted children. We assessed attachment patterns in 20 adoptive dyads and 12 genetically related dyads at two different times: T1 (time 1) within 2 months of adoption and T2 (time 2) 6 months after T1. The children's behavioural attachment patterns were assessed using the Separation-Reunion Procedure and the children's representational (verbal) attachment patterns using the Manchester Child Attachment Story Task. The attachment models of the adoptive mothers were classified using the Adult Attachment Interview. We found that there was a significant enhancement of the late-adopted children's attachment security across the time period considered (P= 0.008). Moreover, all the late-adopted children who showed a change from insecurity to security had adoptive mothers with secure attachment models (P= 0.044). However, the matching between maternal attachment models and late-adopted children's attachment patterns (behaviours and representations) was not significant. Our data suggest that revision of the attachment patterns in the late-adopted children is possible but gradual, and that the adoptive mothers' attachment security makes it more likely to occur. © 2010 Blackwell Publishing Ltd.

Predictors of and outcomes associated with non-adherent behavior among patients on chronic hemodialysis (HD) have been incompletely elucidated. We conducted a post hoc analysis of data from the SMILE trial to identify patient factors associated with non-adherence to dialysis-related treatments and the associations of non-adherence with clinical outcomes. We defined non-adherence as missed HD and abbreviated HD. We used negative binomial regression to model the associations of demographic and clinical factors with measures of non-adherence, and negative binomial and Cox regression to analyze the associations of non-adherence with hospitalizations and mortality, respectively. We followed 286 patients for up to 24 months. Factors independently associated with missing HD included Tuesday/Thursday/Saturday HD schedule [incident rate ratio (IRR) 1.85, p adherence to HD-related treatments, and independent associations of non-adherence with hospitalization and mortality. These findings should inform the development and implementation of interventions to improve adherence and reduce health resource utilization.

Although nonadherence is well documented and strategies for adherence have been shown to be critical to overcoming barriers and improving overall adherence rates, it is unknown how family strategy use is related to adherence in the pediatric renal transplant population. The aims of this study were to assess (a) the strategies used by adolescents with kidney transplants and their caregivers to adhere to the posttransplant oral medication regimen and (b) the relationship of these strategies to objective adherence rates. Semistructured interviews to assess self-management were administered to 17 adolescents (14-18 years) and 17 caregivers. Adherence to oral immunosuppressant medication, measured via electronic monitors, was determined also for a subset of 13 dyads. Common strategies endorsed by families included the following: making it part of the routine (88.2%), verbal reminders by caregiver (82.4%), caregiver verifying medication was taken (76.5%), placing medication in a convenient location (76.5%), and using a pillbox (70.6%). A greater number of family-endorsed strategies were correlated with higher levels of adherence. Of those strategies spontaneously endorsed, only caregiver reminders to take medication and caregiver verification that medications were taken were related significantly to higher adherence rates. The findings highlight the importance of identification and use of specific strategies to improve adherence rates of pediatric renal transplant recipients and emphasize the need for continued caregiver involvement in the promotion of adherence to the treatment regimen.

Full Text Available Adherence to preventive asthma treatment is poor, particularly in children, yet the factors associated with adherence in this age group are not well understood. Adherence was monitored electronically over 6 months in school-aged children who attended a regional emergency department in New Zealand for an asthma exacerbation and were prescribed twice-daily inhaled corticosteroids. Participants completed questionnaires including assessment of family demographics, asthma responsibility and learning style. Multivariable analysis of factors associated with adherence was conducted. 101 children (mean (range age 8.9 (6–15 years, 51% male participated. Median (interquartile range preventer adherence was 30% (17–48% of prescribed. Four explanatory factors were identified: female sex (+12% adherence, Asian ethnicity (+19% adherence, living in a smaller household (−3.0% adherence per person in the household, and younger age at diagnosis (+2.7% for every younger year of diagnosis (all p<0.02. In school-aged children attending the emergency department for asthma, males and non-Asian ethnic groups were at high risk for poor inhaled corticosteroid adherence and may benefit most from intervention. Four factors explained a small proportion of adherence behaviour indicating the difficulty in identifying adherence barriers. Further research is recommended in other similar populations.

Patient adherence has been identified as an important barrier to the implementation of evidence-based psychological treatments. In cognitive behavioral treatments (CBT) for insomnia, the current study examined (a) the validity of therapist ratings of patient agreement and adherence against an established behavioral measure of adherence, and (b) the relationship between treatment agreement, adherence, and outcome. Participants were 188 adults meeting DSM-IV-TR criteria for chronic insomnia who were randomized to receive behavior therapy, cognitive therapy, or CBT for insomnia. Treatment agreement/adherence was measured by (a) weekly therapist ratings of patient agreement and homework completion, and (b) adherence to behavioral strategies (ABS) derived from patient-reported sleep diary. Outcome measures were Insomnia Severity Index and insomnia remission (Insomnia Severity Index adherence, and ABS measures during treatment significantly predicted insomnia remission at posttreatment, and all but therapist rating of homework completion predicted remission at 6-month follow-up. Greater patient agreement and adherence (therapist ratings and ABS) during treatment predicted better treatment outcome. Therapist-rated treatment agreement and adherence correspond well with patient-reported sleep diary-derived adherence measure. These simple, deployable therapist-rated patient agreement and adherence can potentially be useful for treatments for other disorders. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Cell migration is crucial in physiological and pathological processes such as embryonic development and wound healing; such migration is strongly guided by the surrounding nanostructured extracellular matrix. Previous studies have extensively studied the cell migration on anisotropic nanotopographic surfaces; however, only a few studies have reported cell migration on isotropic nanotopographic surfaces. We herein, for the first time, propose a novel concept of adherable area on cell migration using isotropic nanopore surfaces with sufficient nanopore depth by adopting a high aspect ratio. As the pore size of the nanopore surface was controlled to 200, 300, and 400 nm in a fixed center-to-center distance of 480 nm, it produced 86, 68, and 36% of adherable area, respectively, on the fabricated surface. A meticulous investigation of the cell migration in response to changes in the constrained adherable area of the nanotopographic surface showed 1.4-, 1.5-, and 1.6-fold increase in migration speeds and a 1.4-, 2-, and 2.5-fold decrease in the number of focal adhesions as the adherable area was decreased to 86, 68, and 36%, respectively. Furthermore, a strong activation of FAK/Rac1 signaling was observed to be involved in the promoted cell migration. These results suggest that the reduced adherable area promotes cell migration through decreasing the FA formation, which in turn upregulates FAK/Rac1 activation. The findings in this study can be utilized to control the cell migration behaviors, which is a powerful tool in the research fields involving cell migration such as promoting wound healing and tissue repair.

Explaining adherence success in sub-Saharan Africa: an ethnographic study.

Full Text Available Individuals living with HIV/AIDS in sub-Saharan Africa generally take more than 90% of prescribed doses of antiretroviral therapy (ART. This number exceeds the levels of adherence observed in North America and dispels early scale-up concerns that adherence would be inadequate in settings of extreme poverty. This paper offers an explanation and theoretical model of ART adherence success based on the results of an ethnographic study in three sub-Saharan African countries.Determinants of ART adherence for HIV-infected persons in sub-Saharan Africa were examined with ethnographic research methods. 414 in-person interviews were carried out with 252 persons taking ART, their treatment partners, and health care professionals at HIV treatment sites in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda. 136 field observations of clinic activities were also conducted. Data were examined using category construction and interpretive approaches to analysis. Findings indicate that individuals taking ART routinely overcome economic obstacles to ART adherence through a number of deliberate strategies aimed at prioritizing adherence: borrowing and "begging" transport funds, making "impossible choices" to allocate resources in favor of treatment, and "doing without." Prioritization of adherence is accomplished through resources and help made available by treatment partners, other family members and friends, and health care providers. Helpers expect adherence and make their expectations known, creating a responsibility on the part of patients to adhere. Patients adhere to promote good will on the part of helpers, thereby ensuring help will be available when future needs arise.Adherence success in sub-Saharan Africa can be explained as a means of fulfilling social responsibilities and thus preserving social capital in essential relationships.

1997-10-01

Among 23 pediatric renal dialysis patients, we obtained self-reported assessments of psychological adjustment and biochemical and subjective ratings of adherence. Findings indicate elevated levels of depressive symptoms and substantial nonadherence. Depressive symptoms were associated with higher levels of hopelessness, more negative self-perceptions, and more depressogenic attributional style. The psychological adjustment measures did not significantly correlate with adherence. Nonsignificant associations among different measures of adherence underscore its multifaceted nature. Implications for monitoring the adjustment of children on dialysis, assessing adherence, and future research are discussed.

Previously we assessed the medication adherence for oral and topical remedies by a translated Japanese version of the Morisky Medication Adherence Scale-8 (MMAS-8) together with socioeconomic backgrounds in 3096 Japanese dermatological patients, and found the medication adherence, especially to topical drugs, was poor in these patients. In order to elucidate the disease-specific sociomedical factors, we further sub-analyzed the medication adherence in 237 psoriasis patients and compared it with that in other dermatological diseases such as atopic dermatitis, urticaria or tinea. This study was conducted among patients registered in monitoring system and 3096 eligible patients were enrolled. Our web-based questionnaire included the following items such as age, sex, annual income, main health-care institution, experience of effectiveness by oral or topical medication, overall satisfaction with treatment, and MMAS-8 for oral or topical medication. Mean adherence score by MMAS-8 was 5.2 for oral and 4.3 for topical medication. More patients with psoriasis used a university hospital and fewer used a private clinic compared with those with the other skin disease patients. Experience of drug effectiveness by oral medication and overall satisfaction with treatment was lower in psoriasis patients than in other patients. In oral medication, significantly better adherence was observed in those of higher age and with higher annual income. The adherence to medication, especially to topical drugs, was poor in 237 psoriasis patients. We speculated that some severe psoriasis patients were not sufficiently treated systemically and were resistant to topical therapy, leading to poor adherence. © 2015 Japanese Dermatological Association.

Inverting adherent cells for visualizing ECM interactions at the basal cell side

Interactions with the extracellular matrix (ECM) govern a wide range of cellular functions, including survival, migration and invasion. However, in adherent cells these interactions occur primarily on the basal cell side, making them inaccessible to high-resolution, surface-scanning imaging techniques such as atomic force microscopy (AFM) or scanning electron microscopy (SEM). Here we describe a fast and reliable method for inverting adherent cells, exposing the basal cell membrane for direct analysis by AFM or SEM in combination with fluorescence microscopy. Cells including their matrix adhesion sites remain intact during the inversion process and are transferred together with the complete array of basally associated ECM proteins. Molecular features of ECM proteins, such as the characteristic 67 nm collagen D-periodicity, are well preserved after inversion. To demonstrate the versatility of the method, we compared basal interactions of fibroblasts with fibrillar collagen I and fibronectin matrices. While fibroblasts remodel the fibronectin layer exclusively from above, they actively invade even thin collagen layers by contacting individual collagen nanofibrils both basally and apically through a network of cellular extensions. Cell–matrix entanglement coincides with enhanced cell spreading and flattening, indicating that nanoscale ECM interactions govern macroscopic changes in cell morphology. The presented cell inversion technique can thus provide novel insight into nanoscale cell–matrix interactions at the basal cell side. - Highlights: ► We present a novel method for inverting adherent cells to expose the basal cell side. ► Basal cell sides can be imaged at high resolution by AFM and SEM. ► Cells can be inverted together with the underlying extracellular matrix. ► AFM images of inverted cells provide a nanoscale look at basal cell–ECM interactions.

Medication non-adherence is a significant health problem. There are numerous methods for measuring adherence, but no single method performs well on all criteria. The purpose of this systematic review is to (i) identify self-report medication adherence scales that have been correlated with comparison measures of medication-taking behaviour, (ii) assess how these scales measure adherence and (iii) explore how these adherence scales have been validated. Cinahl and PubMed databases were used to search articles written in English on the development or validation of medication adherence scales dating to August 2012. The search terms used were medication adherence, medication non-adherence, medication compliance and names of each scale. Data such as barriers identified and validation comparison measures were extracted and compared. Sixty articles were included in the review, which consisted of 43 adherence scales. Adherence scales include items that either elicit information regarding the patient's medication-taking behaviour and/or attempts to identify barriers to good medication-taking behaviour or beliefs associated with adherence. The validation strategies employed depended on whether the focus of the scale was to measure medication-taking behaviour or identify barriers or beliefs. Supporting patients to be adherent requires information on their medication-taking behaviour, barriers to adherence and beliefs about medicines. Adherence scales have the potential to explore these aspects of adherence, but currently there has been a greater focus on measuring medication-taking behaviour. Selecting the 'right' adherence scale(s) requires consideration of what needs to be measured and how (and in whom) the scale has been validated. © 2013 The British Pharmacological Society.

Treatment adherence in cystic fibrosis (CF) is often poor, however, less is known about adherence to pancreatic enzymes, a critical component of the CF treatment regimen. Parent caregivers often report elevations in depression, and parental depression may adversely affect children's adherence. This prospective study evaluated adherence to pancreatic enzymes in 83 patients (1-13 years) . Adherence was measured across 3 months with electronic pill-caps . Weight was measured at baseline and a 3-month follow-up. Parental depressive symptoms were evaluated by using the Center for Epidemiologic Studies Depression Scale (CES-D). Adherence to pancreatic enzymes was 49.4% ± 3.4%. Adherence was higher at school (94.4% ± 6.1%) than at home (42.3% ± 3.1%), and higher for toddlers (50.6% ± 5.2%) than for school-aged children (37.5% ± 3.7%). Parents reported high rates of depressive symptoms (30% in the clinical range, 18% with moderate symptoms). Children of parents with symptoms of depression versus those without were less adherent (34.8% ± 4.5% vs 48.5% ± 4.1%), and adherence to enzymes was significantly related to 3-month weight outcomes. Average gain in weight z scores across 3 months was 0.5 ± 0.2for children who were >50% adherent and -0.1 ± 6.1for children who were <33% adherent. Parental depression had a signifcant, indirect effect on weight via adherence (-0.005 ± 0.003 gain in weight z score per CES-D unit ). High rates of parental depressive symptoms, coupled with its negative effects on adherence, suggest that measuring and treating parental depression may improve children's adherence to therapy.

The Role of Theory in Increasing Adherence to Prescribed Practice

Richardson, Julie; Wishart, Laurie; Hanna, Steven

2009-01-01

ABSTRACT Purpose: The purpose of this article is to apply theoretical frameworks to adherence behaviour and to guide the development of an intervention to increase adherence to prescribed home programmes. Summary of Key Points: Delivering an effective intervention requires establishing one that is evidence based and of adequate dosage. Two-thirds of patients who receive home exercise prescriptions do not adhere to their home programme, which may contribute to their physiotherapy's being ineffective. The mediating concepts of self-efficacy (SE) and outcome expectations (OE) are common to the five relevant theories used to explain adherence to exercise: the health belief model, protection motivation theory, theory of reasoned action, theory of planned behaviour, and social cognitive theory. Conclusion/Recommendations: Few intervention studies with any theoretical underpinning have examined adherence to exercise. Even fewer have been designed to affect and measure change in the theoretical mediators of SE and OE in patient populations. Physiotherapists must consider increasing adherence as a component of effective physiotherapy. Ongoing research is needed to increase our understanding of adherence to prescribed home programmes and to design interventions to affect theoretical mediators for increasing adherence.

Steinberg, Elizabeth A; Moss, Mary; Buchanan, Cindy L; Goebel, Jens

2018-03-01

Non-adherence remains a significant problem among pediatric (and adult) renal transplant recipients. Non-adherence among solid organ transplant recipients results in US$15-100 million annual costs. Estimates of non-adherence range from 30 to 70% among pediatric patients. Research demonstrates that a 10% decrement in adherence is associated with 8% higher hazard of graft failure and mortality. Focus has begun to shift from patient factors that impact adherence to the contributing healthcare and systems factors. The purpose of this review is to describe problems within the systems implicated in non-adherence and potential solutions that may be related to positive adherence outcomes. Systems issues include insurance and legal regulations, provider and care team barriers to optimal care, and difficulties with transitioning to adult care. Potential solutions include recognition of how systems can work together to improve patient outcomes through improvements in insurance programs, a multi-disciplinary care team approach, evidence-based medical management, pharmacy-based applications and interventions to simplify medication regimens, improved transition protocols, and telehealth/technology-based multi-component interventions. However, there remains a significant lack of reliability in the application of these potential solutions to systems issues that impact patient adherence. Future efforts should accordingly focus on these efforts, likely by leveraging quality improvement and related principles, and on the investigation of the efficacy of these interventions to improve adherence and graft outcomes.

Promoting homework adherence in cognitive-behavioral therapy for adolescent depression.

Jungbluth, Nathaniel J; Shirk, Stephen R

2013-01-01

This study used prospective, observational methods to evaluate six features of therapist behavior as predictors of homework adherence in cognitive-behavioral therapy for adolescent depression, with the goal of identifying therapist strategies with the potential to improve adolescent adherence. Therapist behaviors were expected to interact with initial levels of client resistance or adherence to predict subsequent homework completion. Participants were 50 referred adolescents (33 female, 54% ethnic minority) ages 14 to 18 (M = 15.9) meeting diagnostic criteria for a depressive disorder, and without comorbid psychotic disorder, bipolar disorder, autism spectrum disorder, intellectual disability, or concurrent treatments. Therapist homework-related behaviors were coded from audiotapes of Sessions 1 and 2 and used to predict adolescents' homework adherence, coded from audiotapes of Sessions 2 and 3. Several therapist behaviors were predictive of subsequent homework adherence, particularly for initially resistant or nonadherent adolescents. Stronger homework rationale and greater time allocated to explaining homework in Session 1 predicted greater adherence at Session 2, particularly for initially resistant adolescents. Stronger rationale and eliciting reactions/troubleshooting obstacles in Session 2 predicted greater adherence at Session 3, particularly for adolescents who were less adherent to prior homework. Strategies such as providing a strong rationale, allocating more time to assigning homework, and eliciting reactions/troubleshooting obstacles may be effective ways to bolster homework adherence among initially less engaged, depressed teens.

Full Text Available Danny Decoo,1 Mathieu Vokaer2 1Department of Neurology and Neurorehab, AZ Alma, Sijsele, Belgium; 2Multiple Sclerosis Clinic, Edith Cavell Hospital, CHIREC group, Brussels, Belgium Background: Poor treatment adherence is common among patients with multiple sclerosis (MS. This survey evaluated neurologists’ perception of treatment adherence among MS patients.Materials and methods: This questionnaire-based survey of Belgian neurologists treating MS patients was conducted between June and July 2014. Face-to-face interviews with the neurologists were based on a semistructured questionnaire containing questions regarding the perception of the treatment-adherence level.Results: A total of 41 neurologists participated in the survey. Of these, 88% indicated frequent discussions about treatment adherence as beneficial for treatment efficacy. The mean time spent on the treatment-adherence discussion during the initial consultation was 11 minutes, with 24% of doctors spending 5 minutes and 24% of doctors spending 10 minutes discussing this issue. The majority of neurologists (56% perceived the adherence level in MS as good, and 12% perceived it as excellent. The majority of neurologists (64% indicated intolerance as a main cause of poor adherence, and all neurologists reported insufficient efficacy as a consequence of nonadherence. The importance of adherence in the neurologists’ practice was evaluated on a scale of 1–10, with 1= “not very important” and 10= “very important”: 44% of doctors indicated a score of 10, and the mean score was 9.0.Conclusion: Belgian neurologists consider treatment adherence in MS as essential for the benefits of therapies. However, although neurologists are aware of the consequences of nonadherence, they generally spend limited time discussing the importance of treatment adherence with their patients.

Although U.S. deployment of residential rooftop solar photovoltaic (PV) systems has accelerated in recent years, PV is still installed on less than 1 percent of single-family homes. Most research on household PV adoption focuses on scaling initial markets and modeling predicted growth rather than considering more broadly why adoption occurs. Among the studies that have investigated the characteristics of PV adoption, most collected data from adopters, sometimes with additional non-adopter data, and rarely from people who considered but did not adopt PV. Yet the vast majority of Americans are non-adopters, and they are a diverse group - understanding their ways of evaluating PV adoption is important. Similarly, PV is a unique consumer product, which makes it difficult to apply findings from studies of other technologies to PV. In addition, little research addresses the experience of households after they install PV. This report helps fill some of these gaps in the existing literature. The results inform a more detailed understanding of residential PV adoption, while helping ensure that adoption is sufficiently beneficial to adopters and even non-adopters.

This study aimed to clarify the strategies patients employ to facilitate adherence and determine whether the strategies had an impact on good adherence.Methods: This was a cross-sectional survey using a self-administered questionnaire and review of medical records. Patients diagnosed as having UC and attending one of the outpatient clinics of four urban hospitals from June 2009 to December 2012 were enrolled. A questionnaire was developed to identify the strategies patients employ to facilitate adherence and then administered to patients with UC. Adherence to 5-aminosalicylic acid was calculated, and univariate and multiple logistic regression analyses were performed to determine the strategies that were associated with good adherence.Results: The final analyses included 671 participants (mean age 40.2 years; 54.3% males. The valid response rate was 96.9%; 186 (27.7% participants were classified as non-adherent, the mean adherence rate being 86.1% (standard deviation [SD] 17.9.

Kessler, Michèle

2014-06-01

The kidney transplant recipient is faced not only with the perspective of taking immunosuppressive drugs lifelong, but also the possibility of other long-term treatments prescribed for preexisting conditions, complications, or side effects. Proper management, and most importantly patient adherence, can become a complex challenge. Here we recall current definitions and describe methods for measuring treatment adherence, followed by a discussion on the prevalence of non-adherence in kidney transplant recipients, its effect on graft survival, and factors predictive of non-adherence. Ways of improving adherence are examined, leading to the conviction that helping patients take their medications regularly would probably have a greater impact on graft survival than marketing a new immunosuppressive agent.

Full Text Available Barriers to medication adherence stem from multiple factors. An effective and convenient tool is needed to identify these barriers so that clinicians can provide a tailored, patient-centered consultation with patients. The Modified Drug Adherence Work-up Tool (M-DRAW was developed as a 13-item checklist questionnaire to identify barriers to medication adherence. The response scale was a 4-point Likert scale of frequency of occurrence (1 = never to 4 = often. The checklist was accompanied by a GUIDE that provided corresponding motivational interview-based intervention strategies for each identified barrier. The current pilot study examined the psychometric properties of the M-DRAW checklist (reliability, responsiveness and discriminant validity in patients taking one or more prescription medication(s for chronic conditions. A cross-sectional sample of 26 patients was recruited between December 2015 and March 2016 at an academic medical center pharmacy in Southern California. A priming question that assessed self-reported adherence was used to separate participants into the control group of 17 “adherers” (65.4%, and into the intervention group of nine “unintentional and intentional non-adherers” (34.6%. Comparable baseline characteristics were observed between the two groups. The M-DRAW checklist showed acceptable reliability (13 item; alpha = 0.74 for identifying factors and barriers leading to medication non-adherence. Discriminant validity of the tool and the priming question was established by the four-fold number of barriers to adherence identified within the self-selected intervention group compared to the control group (4.4 versus 1.2 barriers, p < 0.05. The current study did not investigate construct validity due to small sample size and challenges on follow-up with patients. Future testing of the tool will include construct validation.

Adherence of bacteria to prosthetic grafting material is thought to play an important role in the ultimate development of prosthetic infections. To evaluate the role of bacterial adherence in the initiation and colonization of prosthetic materials, Proplast II, Gore-Tex, and silicone were evaluated for adherence of Escherichia coli and Staphylococcus aureus. Bacteria were radiolabeled and incubated with the study material. Adherence was determined by scintillation. Adherence to Proplast II and Gore-Tex reached a maximum at approximately 45 minutes of incubation and demonstrated a detachment phenomenon with E. coli. Similar results were noted with S. aureus, but with a maximal attachment at approximately 30 minutes. Interestingly, bacterial attachment to silicone continued to increase throughout the time of the incubation. In addition, adherence of S. aureus was at a faster rate than E. coli. Attachment of bacteria is a multifactorial process. However, the PTFE graft demonstrates a slower rate of attachment, lower total number of attached bacteria, and faster detachment. The importance of this phenomenon may help explain the foreign body effect of increased susceptibility to infection of foreign materials

As advanced PAP therapy modes (ie, auto-bilevel PAP [ABPAP] or adaptive servo-ventilation [ASV] may address these side effects, we hypothesized such treatment would be associated with decreased expiratory intolerance and increased adherence in posttraumatic stress patients with co-occurring OSA.Methods: We reviewed charts of 147 consecutive adult patients with moderately severe posttraumatic stress symptoms and objectively diagnosed OSA. All patients failed or rejected CPAP and were manually titrated on auto-adjusting, dual-pressure ABPAP or ASV modes in the sleep laboratory, a technique to eliminate flow limitation breathing events while resolving EPI. Patients were then prescribed either mode of therapy. Follow-up encounters assessed patient use, and objective data downloads (ODDs measured adherence.Results: Of 147 charts reviewed, 130 patients were deemed current PAP users, and 102 provided ODDs: 64 used ASV and 38 used ABPAP. ODDs yielded three groups: 59 adherent per insurance conventions, 19 subthreshold compliant partial users, and 24 noncompliant. Compliance based on available downloads was 58%, notably higher than recently reported rates in PTSD patients with OSA. Among the 19 partial users, 17 patients were minutes of PAP use or small percentages of nights removed from meeting insurance compliance criteria for PAP devices.Conclusion: Research is warranted on advanced PAP modes in

Full Text Available Background. The need for a high level of adherence to antiretroviral drugs has remained a major hurdle to achieving maximal benefit from its use in pregnancy. This study was designed to determine the level of adherence and identify factors that influence adherence during pregnancy. Method. This is a cross-sectional study utilizing a semistructured questionnaire. Bivariate and multiple logistic regression models were used to determine factors independently associated with good drug adherence during pregnancy. Result. 137 (80.6% of the interviewed 170 women achieved adherence level of ≥95% using 3 day recall. The desire to protect the unborn child was the greatest motivation (51.8% for good adherence. Fear of being identified as HIV positive (63.6% was the most common reason for nonadherence. Marital status, disclosure of HIV status, good knowledge of ART, and having a treatment supporter were found to be significantly associated with good adherence at bivariate analysis. However, after controlling for confounders, only HIV status disclosure and having a treatment partner retained their association with good adherence. Conclusion. Disclosure of HIV status and having treatment support are associated with good adherence. Maternal desire to protect the child was the greatest motivator for adherence.

Gluten-related disorders are not considered of relevance at public health level in Central America. The prevalence of gluten-related disorders, and adherence to a gluten-free diet, remain unknown in the Central American region. We conducted a cross-sectional survey of the Central American population from San Salvador, El Salvador, to estimate the prevalence rates of self-reported gluten-related disorders and adherence to a gluten-free diet. 1326 individuals were surveyed. Self-reported prevalence rates were (95% Confidence Interval): gluten sensitivity 3.1% (2.3–4.2); physician-diagnosed celiac disease 0.15% (0.04–0.5); wheat allergy 0.75% (0.4–1.3); non-celiac gluten sensitivity 0.98% (0.5–1.6). The prevalence rate of adherence to a gluten-free diet was 7.0% (5.7–8.5). Seven self-reported physician diagnosed gluten-sensitive cases informed the co-existence of non-celiac gluten sensitivity with celiac disease and/or wheat allergy. Among the non-self-reported gluten sensitivity individuals following a gluten-free diet, 50% reported that they were seeing a health professional for gluten-free dietary advice. Gluten sensitivity is commonly reported in Salvadoran population, but some health professionals acknowledge the coexistence of wheat allergy, celiac disease, and non-celiac gluten sensitivity. Among studies at population level, the prevalence of adherence to a gluten-free diet in Salvadoran population is the highest reported until now. However, just a few of the gluten-free diet followers were doing it for health-related benefits; the others reported weight control and the perception that the diet is healthier as the main motivation for adopting such a diet.

Most people complete post-stroke rehabilitation within the first 6 months after stroke even though benefits from exercise are believed to persist well beyond 6 months. Physical and Occupational therapists provide home exercise programs (HEP) to instruct patients on exercises to continue after discharge from rehabilitation. Unfortunately, there is little known about HEP adherence rates in adults with stroke. The objectives of this project were to (1) determine the adherence rate with post-rehabilitation HEP and reasons for non-adherence, (2) assess for interactions between HEP adherence and self-report of depression and fatigue, and (3) determine patient beliefs about the benefit of exercise during stroke recovery. This was a cross-sectional, survey study. A survey was developed and distributed during stroke support group meetings to determine adherence rates with post rehabilitation HEP, reasons for non-adherence, and patient beliefs about the benefit of exercise. Eighty-nine percent of participants reported receiving a HEP and 65.3% of those reported being adherent with at least part of the HEP. Several reasons for non-adherence were identified, including 'doing different exercises than the ones given by the physical therapist', as the most frequently given reason. Study participants identified positive roles of exercise in their recovery from stroke. Patient adherence with HEP after discharge from rehabilitation is less than ideal. Reasons for non-adherence are varied. Rehabilitation therapists need to be able to identify and help patients manage barriers to HEP adherence to promote management of residual deficits.

Resilience and religiosity have received attention as an important process in the experience and management of chronic comorbidities; however, there is no study evaluating resilience in hemodialysis patients and its association with other psychological dimensions or with treatment adherence. This observational prospective study assessed resilience (25 item Wagnild and Young Resilience Scale), religiosity under three dimensions (organizational, non-organizational and intrinsic) using DUREL scale, depressive symptoms (Patient Health Questionnaire-9) and health-related quality of life (Short Form-36 questionnaire). The main outcomes were medication adherence using the Morisky Medication Adherence Scale-8 (MMAR-8) and the missing/shortened dialysis sessions in the following six months. Of 208 patients approached, 202 (97.1%) agreed to participate. One hundred twenty-three patients (60.9%) were males and mean age was 52.8 ± 14.8 years-old. The median time on hemodialysis was 36 months (IQR, 12, 84). 82 (40.6%) patients obtained a MMAS-8 score adherence'. Overall, the mean score of medication adherence was low (5.7 ± 2.1). About adherence to hemodialysis sessions, patients missed a total of 234 (1.6%) hemodialysis sessions. Forty-eight patients (23.7%) missed an average of at least three sessions in six months. Regarding adherence to medication, there was no association in the uni- or multivariate analysis between religiosity dimensions and MMAS-8 score. After adjustment, resilience was positively associated with MMAS-8 score (standardized β coefficient .239, p = .016). Organized and intrinsic religiosity were associated with adherence to dialysis sessions (standardized β coefficient .258, p = .004 and .231, p = .026, respectively). Interestingly, opposite to medication adherence, more resilient patients were associated with less adherence to hemodialysis sessions (standardized β coefficient -.296, p = .001). Religiosity was associated with dialysis

Is Inconsistent Pre-treatment Bedtime Related to CPAP Non-Adherence?

Lack of adherence to continuous positive airway pressure therapy (CPAP) limits the effectiveness of treatment of obstructive sleep apnea (OSA). We hypothesized that an irregular bedtime would be negatively related to regular use of CPAP treatment. If so, modifying bedtime schedule may address the persistent problem of inconsistent CPAP use in adults with OSA. In a prospective longitudinal study, we examined whether inconsistent self-reported bedtime before initiation of CPAP treatment, operationalized as bedtime variability, was (1) different among those adherent (≥ 4 hours per night) and non-adherent to CPAP treatment at one week and one month; and/or (2) was related to one-week and one-month CPAP use when other variables were accounted for. Consecutively-recruited newly-diagnosed OSA adults (N=79) completed sleep diaries prior to CPAP treatment. One-week and one-month objective CPAP use data were collected. Pre-treatment bedtime variability was different among CPAP non-adherers and adherers at one month and was a significant predictor of non-adherence at one month in multivariate analyses. The odds of one-month CPAP non-adherence were 3.5 times greater in those whose pre-treatment bedtimes varied by >75 minutes. Addressing sleep schedule prior to CPAP initiation may be an opportunity to improve CPAP adherence. PMID:25353159

The aim of this study was to evaluate Staphylococcus sp adhesion to modified surfaces of anodized titanium alloy (Ti-6Al-4V). Surface modification involved generation of fluoride-containing titanium oxide nanotube films. Specimens of Ti-6Al-4V alloy 6-4 ELI-grade 23- meets the requirements of ASTM F136 2002A (AMS 2631B class A1) were anodized in a mixture of sulphuric/hydrofluoric acid at 20 V for 5 and 60 min to form a 100 nm-thick porous film of 20 nm pore diameter and 230 nm-thick nanotube films of 100 nm in diameter. The amount of fluorine in the oxide films was of 6% and of 4%, respectively. Collection strains and six clinical strains each of Staphylococcus aureus and Staphylococcus epidermidis were studied. The adherence study was performed using a previously published protocol by Kinnari et al. The experiments were performed in triplicates. As a result, lower adherence was detected for collection strains in modified materials than in unmodified controls. Differences between clinical strains were detected for both species (p<0.0001, Kruskal-Wallis test), although global data showed similar results to that of collection strains (p<0.0001, Kruskal-Wallis test). Adherence of bacteria to modified surfaces was decreased for both species. The results also reflect a difference in the adherence between S. aureus and S. epidermidis to the modified material. As a conclusion, not only we were able to confirm the decrease of adherence in the modified surface, but also the need to test multiple clinical strains to obtain more realistic microbiological results due to intraspecies differences.

Factors associated with false-positive self-reported adherence to antihypertensive drugs.

Tedla, Y G; Bautista, L E

2017-05-01

Self-reported medication adherence is known to overestimate true adherence. However, little is known about patient factors that may contribute to the upward bias in self-reported medication adherence. The objective of this study is to examine whether demographic, behavioral, medication and mood factors are associated with being a false-positive self-reported adherer (FPA) to antihypertensive drug treatment. We studied 175 patients (mean age: 50 years; 57% men) from primary-care clinics starting antihypertensive drug treatment. Self-reported adherence (SRA) was measured with the Medication Adherence Report Scale (MARS) and by the number of drug doses missed in the previous week/month, and compared with pill count adherence ratio (PCAR) as gold standard. Data on adherence, demographic, behavioral, medication and mood factors were collected at baseline and every 3 months up to 1 year. FPA was defined as being a non-adherer by PCAR and an adherer by self-report. Mixed effect logistic regression was used for the analysis. Twenty percent of participants were FPA. Anxiety increased (odds ratio (OR): 3.00; P=0.01), whereas smoking (OR: 0.40; P=0.03) and drug side effects (OR: 0.46, P=0.03) decreased the probability for FPA by MARS. Education below high-school completion increased the probability of being an FPA as measured by missing doses in the last month (OR: 1.66; P=0.04) and last week (OR: 1.88; P=0.02). The validity of SRA varies significantly according to drug side effects, behavioral factors and patient's mood. Careful consideration should be given to the use of self-reported measures of adherence among patients likely to be false-positive adherers.

counseling in problem cases for diabetics, different family based interventions including repeated family counseling, education and "culturally modified family therapy" in patients with schizophrenia, repeated "compliance therapy" sessions for patients with acute psychosis. For other interventions the results should be viewed with more concern (because of the poor methodical quality of the underlying studies. The effect size of the interventions can not be estimated from the available data. From the available data, no reliable results can be provided concerning the cost-benefit relation of these strategies. Discussion: Many of the reported studies had a poor reporting and methodological quality. The reliability of the conclusions of the studies is restricted because of methodical shortcomings. Efficacy and cost estimates determined in the health economic studies are not transferable to the current situation in Germany. It has been discussed recently that the compliance or adherence enhancing interventions can restrict the autonomy and the privacy of the patients. Conclusions: In drug therapy some compliance or adherence enhancing interventions with concomitant positive effect on the treatment outcome may be used. The cost-benefit relation of these interventions is to be estimated. Using these interventions the patient’s autonomy and privacy are to be restricted as few as possible.

Measuring medication adherence in patients with incident hypertension: a retrospective cohort study.

Though pharmacy claims data are commonly used to study medication adherence, there remains no standard operational definition for adherence especially for patients on multiple medications. Even when studies use the same terminology, the actual methods of calculating adherence can differ drastically. It is unclear whether the use of different definitions results in different conclusions regarding adherence and associated outcomes. The objective of our study was to compare adherence rates and associations with mortality using different operational definitions of adherence, and using various methods of handling concurrent medication use. We conducted a cohort study of patients aged ≥65 years from Manitoba, Canada, with incident hypertension diagnosed in 2004 and followed to 2009. We calculated adherence rates to anti-hypertensive medications using different operational definitions of medication adherence (including interval and prescription based medication possession ratios [MPR] and proportion of days covered [PDC]). For those on concurrent medications, we calculated adherence rates using the different methods of handling concurrent medication use, for each definition. We used logistic regression to determine the association between adherence and mortality for each operational definition. Among 2199 patients, 24.1% to 90.5% and 71.2% to 92.7% were considered adherent when using fixed interval and prescription-based interval medication possession ratios [MPRi and MPRp] respectively, depending on how concurrent medications were handled. Adherence was inversely associated with death, with the strongest association for MPRp measures. This association was significant only when considering adherence to any anti-hypertensive [aOR 0.70, 95% CI 0.51, 0.97], or when the mean of the class-specific MPRp's [adjusted OR 0.71, 95% CI 0.53, 0.95] was used. No significant association existed when the highest or lowest class-specific MPRp was used as the adherence estimate. The

Transcultural adaptation and validation of the Celiac Dietary Adherence Test: a simple questionnaire to measure adherence to a gluten-free diet

Directory of Open Access Journals (Sweden)

Ricardo Fueyo-Díaz

Full Text Available Background and aims: A gluten-free diet is to date the only treatment available to celiac disease sufferers. However, systematic reviews indicate that, depending on the method of evaluation used, only 42% to 91% of patients adhere to the diet strictly. Transculturally adapted tools that evaluate adherence beyond simple self-informed questions or invasive analyses are, therefore, of importance. The aim is to obtain a Spanish transcultural adaption and validation of Leffler's Celiac Dietary Adherence Test. Methods: A two-stage observational transversal study: translation and back translation by four qualified translators followed by a validation stage in which the questionnaire was administered to 306 celiac disease patients aged between 12 and 72 years and resident in Aragon. Factorial structure, criteria validity and internal consistency were evaluated. Results: The Spanish version maintained the 7 items in a 3-factor structure. Feasibility was very high in all the questions answered and the floor and ceiling effects were very low (4.3% and 1%, respectively. The Spearman correlation with the self-efficacy and life quality scales and the self-informed question were statistically significant (p < 0.01. According to the questionnaire criteria, adherence was 72.3%. Conclusion: The Spanish version of the Celiac Dietary Adherence Test shows appropriate psychometric properties and is, therefore, suitable for studying adherence to a gluten-free diet in clinical and research environments.

2011-11-01

In this study, we discuss the relevance of adoptive families' satisfaction in the assessment of adoption processes. The effects of adoption on a sample group of 272 adoptive families are analyzed. Most families show high levels of satisfaction as to: their decision to adopt, the features of their adopted children and how adoption has affected them as individuals and as a family. Statistical analyses show that these families can have different satisfaction levels depending on certain features of the adoptees, of the adoptive families or of their educational style. Life satisfaction of the adoptees is also related to how their adoptive parents evaluate the adoption.

Full Text Available The main task of the general practitioner is managing patients with the effects of ischemic stroke. The improvement of patients adherence to treatment in a significant way contributes to successful secondary prevention of ischemic stroke. Adherence to treatment can be determined through various questionnaires, including Morissky-Green. Currently, the adherence to a long-term drug therapy remains insufficient.

The integrity of reactor vessel may be threatened by the heat generation at the oxide pool and to the natural convection heat transfer to the reactor vessel by those two layers. Therefore, External Reactor Vessel Cooling (ERVC) is performed in order to secure the integrity of the reactor vessel. Whether the IVR(In-Vessel Retention) Strategy can be applicable to a larger reactor is the technical concern, which nourished the research interest for the natural convection heat transfer of metal and oxide pool and ERVC performance. Especially, it is hard to simulate oxide pool by experimentally due to the high level of buoyancy. Moreover, the volumetrically exothermic working fluid should be adopted to simulate the behavior of the core melts. Therefore, the volumetric heat sources that immersed in the working fluid have been adopted to simulate oxide pool by experiment. We investigated oxide pool with two different designs of the volumetric heat sources that adopted previous experiments. The investigation was performed by mass transfer experiment using analogy between heat and mass transfers. The results were compared to previous studies. We simulated the natural convection heat transfer of the oxide pool by mass transfer experiment. The isothermally cooled condition was established by limiting current technique firstly. The results were compared to previous studies under identical design of the volumetric heat sources. The average Nu's of the curvature and the top plate were close to the previous studies.

Although guideline-based asthma care and adherence to inhaled corticosteroids are predictors of asthma control, the role of adherence in maintaining long-term asthma control is largely unknown. This study was designed to explore the relationship between adherence to inhaled corticosteroids and long-term asthma control in young children with asthma. In this observational study, 81 2-6-year-old asthmatic children, using inhaled corticosteroids, closely followed-up in a programme with extensive self-management training, were enrolled. Adherence was measured daily for 12 months using Smartinhaler (Nexus6 Ltd, Auckland, New Zealand) devices. Long-term asthma control was assessed by parents and physicians and included clinical assessment, an asthma control questionnaire and lung function measurement. We examined the association of adherence to asthma control, adjusting for seasonal influences and clinical characteristics. Median (interquartile range) adherence was 87% (70-94%), and 64 (79%) children had well-controlled asthma throughout follow-up. Adherence >80% was associated with better asthma control, and we found no important confounders of this association. Children with persistent mild symptoms had lower adherence rates (p=0.028). Guideline-based asthma care was associated with good asthma control in most children. Adherence to inhaled corticosteroids was an independent strong predictor of long-term asthma control, with highest levels of asthma control found in children with adherence >80% of doses prescribed.

To Adopt Or Not To Adopt? The Transnational Adoption of International Financial Reporting Standards (IFRS) in Africa

2015-01-01

The idea that policy diffusion can occur via two different mechanisms has gained attention in the realm of international accounting since the European Union’s adoption of International Financial Reporting Standards (IFRSs) in 2005. Proponents of classical economic approaches to policy adoption argue that countries adopting IFRS are motivated solely by the economic consequences of the standards from which they anticipate an improvement in information quality. Neo-institutional scholars argue, ...

Poor adherence to long-term antipsychotic injectable (LAI) medication in patients with psychotic disorders is associated with a range of negative outcomes. No psychosocial intervention has been found to be consistently effective in improving adherence. To test whether or not offering financial incentives is effective and cost-effective in improving adherence and to explore patient and clinician experiences with such incentives. A cluster randomised controlled trial with economic and nested qualitative evaluation. The intervention period lasted for 12 months with 24 months' follow-up. The unit of randomisation was mental health teams in the community. Community teams in secondary mental health care. Patients with a diagnosis of schizophrenia, schizoaffective psychosis or bipolar illness, receiving ≤ 75% of their prescribed LAI medication. In total, 73 teams with 141 patients (intervention n = 78 and control n = 63) were included. Participants in the intervention group received £15 for each LAI medication. Patients in the control group received treatment as usual. adherence to LAI medication (the percentage of received out of those prescribed). percentage of patients with at least 95% adherence; clinical global improvement; subjective quality of life; satisfaction with medication; hospitalisation; adverse events; and costs. Qualitative evaluation: semistructured interviews with patients in the intervention group and their clinicians. outcome data were available for 131 patients. Baseline adherence was 69% in the intervention group and 67% in the control group. During the intervention period, adherence was significantly higher in the intervention group than in the control group (85% vs. 71%) [adjusted mean difference 11.5%, 95% confidence interval (CI) 3.9% to 19.0%; p = 0.003]. Secondary outcome: patients in the intervention group showed statistically significant improvement in adherence of at least 95% (adjusted odds ratio 8.21, 95% CI 2.00 to 33

Improving medication adherence: a framework for community pharmacy-based interventions

Full Text Available Janice Pringle,1 Kim C Coley2 1Program Evaluation and Research Unit, Department of Pharmacy and Therapeutics, School of Pharmacy, University of Pittsburgh, Pittsburgh, PA, USA; 2Department of Pharmacy and Therapeutics, School of Pharmacy, University of Pittsburgh, Pittsburgh, PA, USA Abstract: Evidence supports that patient medication adherence is suboptimal with patients typically taking less than half of their prescribed doses. Medication nonadherence is associated with poor health outcomes and higher downstream health care costs. Results of studies evaluating pharmacist-led models in a community pharmacy setting and their impact on medication adherence have been mixed. Community pharmacists are ideally situated to provide medication adherence interventions, and effective strategies for how they can consistently improve patient medication adherence are necessary. This article suggests a framework to use in the community pharmacy setting that will significantly improve patient adherence and provides a strategy for how to apply this framework to develop and test new medication adherence innovations. The proposed framework is composed of the following elements: 1 defining the program's pharmacy service vision, 2 using evidence-based, patient-centered communication and intervention strategies, 3 using specific implementation approaches that ensure fidelity, and 4 applying continuous evaluation strategies. Within this framework, pharmacist interventions should include those services that capitalize on their specific skill sets. It is also essential that the organization's leadership effectively communicates the pharmacy service vision. Medication adherence strategies that are evidence-based and individualized to each patient's adherence problems are most desirable. Ideally, interventions would be delivered repeatedly over time and adjusted when patient's adherence circumstances change. Motivational interviewing principles are particularly well

Self-report is the most common method of measuring medication adherence but is influenced by recall error and response bias, and it typically does not provide insight into the causes of poor adherence. Ecological momentary assessment (EMA) of health behaviors using mobile phones offers a promising alternative to assessing adherence and collecting related data that can be clinically useful for adherence problem solving. To determine the feasibility of using EMA via mobile phones to assess adolescent asthma medication adherence and identify contextual characteristics of adherence decision making. We utilized a descriptive and correlational study design to explore a mobile method of symptom and adherence assessment using an interactive voice response system. Adolescents aged 12-18 years with a diagnosis of asthma and prescribed inhalers were recruited from an academic medical center. A survey including barriers to mobile phone use, the Illness Management Survey, and the Pediatric Asthma Quality of Life Questionnaire were administered at baseline. Quantitative and qualitative assessment of asthma symptoms and adherence were conducted with daily calls to mobile phones for 1 month. The Asthma Control Test (ACT) was administered at 2 study time points: baseline and 1 month after baseline. The sample consisted of 53 adolescents who were primarily African American (34/53, 64%) and female (31/53, 58%) with incomes US$40K/year or lower (29/53, 55%). The majority of adolescents (37/53, 70%) reported that they carried their phones with them everywhere, but only 47% (25/53) were able to use their mobile phone at school. Adolescents responded to an average of 20.1 (SD 8.1) of the 30 daily calls received (67%). Response frequency declined during the last week of the month (b=-0.29, PMobile phones provided a feasible method to assess asthma symptoms and adherence in adolescents.

Patients' adherence with posttransplant immunosuppression is known to affect renal transplant outcomes. Prospectively, individual medication adherence patterns in 195 kidney transplant recipients were quantified with electronic medication monitors. Monitored drugs were mycophenolate mofetil, sirolimus, or azathioprine. Monitoring began at hospital discharge and continued an average of 15±8 months. Patient follow-up for clinical outcomes averaged 8±3 years. Each month's adherence percentage was calculated as the sum of daily adherence percents, divided by the number of evaluable days. During the first 3 months after transplantation, patients (n=44) with declining medication adherence, defined as dropping by 7% or higher (equal to missing 2 days) between months 1 and 2, later experienced lower mean medication adherence for months 6 to 12, 73% versus 92% respectively (Padherence, they also had more frequent (P=0.034) and earlier (P=0.065) acute rejection episodes. This was additionally associated with more frequent (P=0.017) and earlier (P=0.046) death-censored graft loss.In addition, daily medication adherence, expressed as the percentage of doses taken, decreased as the number of prescribed daily doses increased. During the first 3 months after transplantation, adherence with four doses per day averaged 84%, compared to 91% for patients on twice-daily dosing (P=0.024) and 93.5% for patients on once-daily dosing (P=0.008). Early declining medication nonadherence is associated with adverse clinical outcomes. This pattern is detectable during the first 2 months after transplantation. Early detection of nonadherence provides opportunities to target interventions toward patients at the highest risk for adverse behaviors and events.

This study assessed relationships among internalizing symptoms, barriers to medication adherence, and medication adherence in adolescents with solid organ transplants. The sample included 72 adolescents who had received solid organ transplants. Multiple mediator models were tested via bootstrapping methods. Bivariate correlations revealed significant relationships between barriers and internalizing symptoms of depression, anxiety, and posttraumatic stress, as well as between internalizing symptoms and medication adherence. Barriers indicative of adaptation to the medication regimen (e.g., forgetting, lack of organization) were related to medication adherence and mediated the relationship between internalizing symptoms and medication adherence. These findings indicate that barriers may serve as a more specific factor in the relationship between more general, pervasive internalizing symptoms and medication adherence. Results may help guide areas for clinical assessment, and the focus of interventions for adolescent transplant recipients who are experiencing internalizing symptoms and/or who are nonadherent to their medication regimen.

Korff, Lynn Von; Grotevant, Harold D.

2012-01-01

The present study examined adoption-related family conversation as a mediator of the association between adoptive parents’ facilitation of contact with birth relatives and adolescent adoptive identity formation. The sample consisted of 184 adoptive families. Data were collected in two waves from adoptive mothers and fathers, and adoptees (M = 15.68 years at adolescence; M = 24.95 years at emerging adulthood) using semistructured interviews and questionnaires. Structural equation models showed a good fit to sample data, and analyses supported the hypothesized mediation model. Contact with birth relatives is associated with more frequent adoption-related family conversation, which in turn is associated with the development of adoptive identity. These results highlight the importance of supporting activities such as contact that lead to adoption-related family conversation. PMID:21517175

The authors explored the relationship between critical elements of medication management appointments (appointment length, patient-centered talk, and positive nonverbal affect among providers) and patient appointment adherence. The authors used an exploratory, cross-sectional design employing quantitative analysis of 83 unique audio recordings of split treatment medication management appointments for 46 African-American and 37 white patients with 24 psychiatrists at four ambulatory mental health clinics. All patients had a diagnosis of depression. Data collected included demographic information; Patient Health Questionnaire-9 scores for depression severity; psychiatrist verbal and nonverbal communication behaviors during medication management appointments, identified by the Roter Interaction Analysis System during analysis of audio recordings; and appointment adherence. Bivariate analyses were employed to identify covariates that might influence appointment adherence. Generalized estimating equations (GEEs) were employed to assess the relationship between appointment length, psychiatrist patient-centered talk, and positive voice tone ratings and patient appointment adherence, while adjusting for covariates and the clustering of observations within psychiatrists. Wald chi square analyses were used to test whether all or some variables significantly influenced appointment adherence. GEE revealed a significant relationship between positive voice tone ratings and appointment adherence (p=.03). Chi square analyses confirmed the hypothesis of a positive and significant relationship between appointment adherence and positive voice tone ratings (p=.03) but not longer visit length and more patient-centered communication. The nonverbal conveyance of positive affect was associated with greater adherence to medication management appointments by depressed patients. These findings potentially have important implications for communication skills training and adherence research.

It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD) therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions). A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of non-adherence varied across studies: 2.6-53% for dialysis exchanges, 3.9-85% for medication, and 14.4-67% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient population.

Smoking is highly prevalent among HIV+ individuals and studies indicate that it may be associated with poor ART adherence, though the relationship is poorly understood. In addition little is known about interest in quitting among HIV+ smokers who are having adherence difficulties. We examined smoking and ART adherence among 203 HIV+ individuals enrolled in a randomized trial of interventions to increase ART adherence. Prior analyses indicated there were no overall treatment group effects. Smoking status and motivation to quit was assessed at baseline and ART adherence was assessed at week 12, 24, 36, and 48. Longitudinal generalized estimating equation analysis that controlled for treatment group revealed that smoking status was not significantly related to adherence over time. Motivation to quit was high with 58 % intending to quit in the next 6 months and 25 % intending to quit in the next 30 days. Findings suggest that smoking is not associated with adherence among those with adherence difficulties. However it does not diminish importance of addressing both behaviors especially given HIV+ smokers substantial interest in changing smoking behavior.

The patient's duty to adhere to prescribed treatment: an ethical analysis.

Science.gov (United States)

Resnik, David B

2005-04-01

This article examines the ethical basis for the patient's duty to adhere to the physician's treatment prescriptions. The article argues that patients have a moral duty to adhere to the physician's treatment prescriptions, once they have accepted treatment. Since patients still retain the right to refuse medical treatment, their duty to adhere to treatment prescriptions is a prima facie duty, which can be overridden by their other ethical duties. However, patients do not have the right to refuse to adhere to treatment prescriptions if their non-adherence poses a significant threat to other people. This paper also discusses the use of written agreements between physicians and patients as a strategy for promoting patient adherence.

With user fees now seen as a major hindrance to universal health coverage, many countries have introduced fee reduction or elimination policies, but there is growing evidence that adherence to reduced fees is often highly imperfect. In 2004, Kenya adopted a reduced and uniform user fee policy providing fee exemptions to many groups. We present data on user fee implementation, revenue and expenditure from a nationally representative survey of Kenyan primary health facilities. Data were collected from 248 randomly selected public health centres and dispensaries in 2010, comprising an interview with the health worker in charge, exit interviews with curative outpatients, and a financial record review. Adherence to user fee policy was assessed for eight tracer conditions based on health worker reports, and patients were asked about actual amounts paid. No facilities adhered fully to the user fee policy across all eight tracers, with adherence ranging from 62.2% for an adult with tuberculosis to 4.2% for an adult with malaria. Three quarters of exit interviewees had paid some fees, with a median payment of US dollars (USD) 0.39, and a quarter of interviewees were required to purchase additional medical supplies at a later stage from a private drug retailer. No consistent pattern of association was identified between facility characteristics and policy adherence. User fee revenues accounted for almost all facility cash income, with average revenue of USD 683 per facility per year. Fee revenue was mainly used to cover support staff, non-drug supplies and travel allowances. Adherence to user fee policy was very low, leading to concerns about the impact on access and the financial burden on households. However, the potential to ensure adherence was constrained by the facilities' need for revenue to cover basic operating costs, highlighting the need for alternative funding strategies for peripheral health facilities.

Inhibitors of e-Government adoption: Determinants of habit and adoption intentions

Manuel Rey-Moreno

2017-09-01

Full Text Available Explanatory models of e-Government adoption are based on the premise that user behavior results from users’ intentions, which derive from users’ beliefs and attitudes. According to such models, citizens’ high intentions to use e-Government tools should have led to the widespread adoption of these tools. Yet this has not occurred. Therefore, existing models fail to explain the adoption of e-Government. These models must be complemented to explain the cause of citizens’ failure to adopt e-Government. Attempts to build a satisfactory model include the design of dual models (jointly analyzing facilitators and inhibitors and integrating models (jointly analyzing the interaction between intention and habit in prompting behavior. This study identified several inhibitors of e-Government adoption. Organizational support, self-efficacy, benefits, loss aversion, regret aversion, control, transition costs, sunk costs/switching costs, uncertainty, habit, resistance, and inertia were found to inhibit citizens’ adoption of e-Government.

Method of detaching adherent cells for flow cytometry

KAUST Repository

Kaur, Mandeep

2015-12-24

In one aspect, a method for detaching adherent cells can include adding a cell lifting solution to the media including a sample of adherent cells and incubating the sample of adherent cells with the cell lifting solution. No scraping or pipetting is needed to facilitate cell detachment. The method do not require inactivation of cell lifting solution and no washing of detaching cells is required to remove cell lifting solution. Detached cells can be stained with dye in the presence of cell lifting solution and are further analyzed using flow cytometer. The method has been tested using 6 different cell lines, 4 different assays, two different plate formats (96 and 384 well plates) and two different flow cytometry instruments. The method is simple to perform, less time consuming, with no cell loss and makes high throughput flow cytometry on adherent cells a reality.

[Concept analysis of medication adherence in patients with chronic disease].

Pharmacotherapy plays an important role in the management of chronic diseases. However, many patients with chronic disease do not adhere to their medication regimen. This results in worsening symptoms and frequent re-hospitalizations. As a result, healthcare providers may view these patients as bad. Medication adherence is a complex concept. Analyzing this concept may assist nurses to improve patient-centered care. This paper uses Walker & Avant's method to conduct a concept analysis of medication adherence. Results show the defining attributes of medication adherence as: (1) knowing and agreeing to the medication; (2) communicating and negotiating the regimen; and (3) active, continuous involvement in and appraisal of the treatment effect. Identified antecedents of medication adherence included the patient having: (1) a prescribed medication regimen; (2) cognitive and action abilities in her / his role as a patient; and (3) level of preparation for medication treatment. Identified consequences of medication adherence include: (1) improving symptom control; (2) decreasing re-hospitalizations and mortality; (3) reducing medical care costs; (4) restoring self-esteem; and (5) diminishing depression. It is hoped that this concept analysis provides a reference for nurses to achieve a better understanding of medication adherence and further improve nursing practice.

The present study examined adoption-related family conversation as a mediator of the association between adoptive parents' facilitation of contact with birth relatives and adolescent adoptive identity formation. The sample consisted of 184 adoptive families. Data were collected in two waves from adoptive mothers and fathers, and adoptees (M = 15.68 years at adolescence; M = 24.95 years at emerging adulthood) using semistructured interviews and questionnaires. Structural equation models showed a good fit to sample data, and analyses supported the hypothesized mediation model. Contact with birth relatives is associated with more frequent adoption-related family conversation, which in turn is associated with the development of adoptive identity. These results highlight the importance of supporting activities such as contact that lead to adoption-related family conversation. 2011 APA, all rights reserved

An effective technology transfer program is a necessary and significant step towards independence in nuclear power technology. Attaining success in the conduct of such a program is a result of a) the donor and recipient jointly understanding the fundamental concepts of the learning process, b) sharing a mutual philosophy involving a partnership relationship, c) joint and careful planning, d) rigorous adherence to proven project management techniques, and e) presence of adequate feedback to assure continuing success as the program proceeds. Several years ago, KEPCO President Park, Jung-KI presented a paper on technology in which he stated, 'Nuclear technology is an integration of many unit disciplines, and thus requires extensive investment and training in order to establish the base for efficient absorption of transferred technology.' This paper addresses President Park's observations by discussing the philosophy, approach, and mechanisms that are necessary to support an efficient and effective process of nuclear power technology transfer. All technical content and presentation methods discussed are based on a technology transfer program developed by Stone and Webster, as an Engineer/Constructor for nuclear power plants, and are designed and implemented to promote the primary program goal - the ability of the trainees and the organization to perform specific nuclear power related multi-discipline function independently and competitively

In a research context, self-management solutions, which may range from simple book diaries to complex telehealth packages, designed to facilitate patients in managing their long-term conditions, have often shown cost-effectiveness, but their implementation in practice has frequently been challenging. We conducted an interpretive qualitative synthesis of relevant articles identified through systematic searches of bibliographic databases in July 2014. We searched PubMed (Medline/NLM), Web of Science, LISTA (EBSCO), CINAHL, Embase and PsycINFO. Coding and analysis was inductive, using the framework method to code and to categorise themes. We took a sensemaking approach to the interpretation of findings. Fifty-eight articles were selected for synthesis. Results showed that during adoption, factors identified as facilitators by some were experienced as barriers by others, and facilitators could change to barriers for the same adopter, depending on how adopters rationalise the solutions within their context when making decisions about (retaining) adoption. Sometimes, when adopters saw and experienced benefits of a solution, they continued using the solution but changed their minds when they could no longer see the benefits. Thus, adopters placed a positive value on the solution if they could constructively rationalise it (which increased adoption) and attached a negative rationale (decreasing adoption) if the solution did not meet their expectations. Key factors that influenced the way adopters rationalised the solutions consisted of costs and the added value of the solution to them and moral, social, motivational and cultural factors. Considering 'barriers' and 'facilitators' for implementation may be too simplistic. Implementers could instead iteratively re-evaluate how potential facilitators and barriers are being experienced by adopters throughout the implementation process, to help adopters to retain constructive evaluations of the solution. Implementers need to pay

Background: With emerging use of ME-health technology, there is a growing interest in evaluating the effectiveness of the tools on medication adherence. Examples of ME-health technology-based tools include text message-based pill reminders and Web-based patient education. Methods: MEDLINE, Cochrane Library, and Web of Science were searched for articles on adherence to acne treatment published through November 2013. A combination of search terms such as "acne" and "adherence" or "compliance" were used. Results: Adherence to oral acne medication was higher than for topical acne medication. The frequency of office visits was also an influencing factor for acne treatment adherence. The telephone-based reminders on a daily basis did not improve acne patients' medication adherence, whereas the Web-based educational tools on a weekly basis had a positive effect on medication adherence in acne treatment. Conclusion: In using ME-health interventions, factors such as medication dosage forms, frequency of intervention, and patients' preferences should be taken into consideration. Developing disease-specific text message reminders may be helpful to increase adherence rates. In addition, a combination of text message reminders with another type of intervention may improve medication adherence.

Several technologies have been proposed to support the reduction of insomnia complaints. A user-centered assessment of these technologies could provide insight into underlying factors related to treatment adherence. Gaining insight into adherence to technology-mediated insomnia treatment as a solid base for improving those adherence rates by applying adherence-enhancing strategies. Adherence to technology-mediated sleep products was studied in three ways. First, a meta-analysis was performed to investigate adherence rates in technology-mediated insomnia therapy. Several databases were queried for technology-mediated insomnia treatments. After inclusion and exclusion steps, data from 18 studies were retrieved and aggregated to find an average adherence rate. Next, 15 semistructured interviews about sleep-support technologies were conducted to investigate perceived adherence. Lastly, several scenarios were written about the usage of a virtual sleep coach that could support adherence rates. The scenarios were discussed in six different focus groups consisting of potential users (n=15), sleep experts (n=7), and coaches (n=9). From the meta-analysis, average treatment adherence appeared to be approximately 52% (95% CI 43%-61%) for technology-mediated insomnia treatments. This means that, on average, half of the treatment exercises were not executed, suggesting there is a substantial need for adherence and room for improvement in this area. However, the users in the interviews believed they adhered quite well to their sleep products. Users mentioned relying on personal commitment (ie, willpower) for therapy adherence. Participants of the focus groups reconfirmed their belief in the effectiveness of personal commitment, which they regarded as more effective than adherence-enhancing strategies. Although adherence rates for insomnia interventions indicate extensive room for improvement, users might not consider adherence to be a problem; they believe willpower to be an

Open Channel Natural Convection Heat Transfer on a Vertical Finned Plate

Park, Joo Hyun; Heo, Jeong Hwan; Chung, Bum Jin

2013-01-01

The natural convection heat transfer of vertical plate fin was investigated experimentally. Heat transfer systems were replaced by mass-transfer systems, based on the analogy concept. The experimental results lie within the predictions of the existing heat transfer correlations of plate-fin for the natural convections. An overlapped thermal boundary layers caused increasing heat transfer, and an overlapped momentum boundary layers caused decreasing heat transfer. As the fin height increases, heat transfer was enhanced due to increased inflow from the open side of the fin spacing. When fin spacing and fin height are large, heat transfer was unaffected by the fin spacing and fin height. Passive cooling by natural convection becomes more and more important for the nuclear systems as the station black out really happened at the Fukushima NPPs. In the RCCS (Reactor Cavity Cooling System) of a VHTR (Very High Temperature Reactor), natural convection cooling through duct system is adopted. In response to the stack failure event, extra cooling capacity adopting the fin array has to be investigated. The finned plate increases the surface area and the heat transfer increases. However, the plate of fin arrays may increase the pressure drop and the heat transfer decreases. Therefore, in order to enhance the passive cooling with fin arrays, the parameters for the fin arrays should be optimized. According to Welling and Wooldridge, a natural convection on vertical plate fin is function of Gr, Pr, L, t, S, and H. The present work investigated the natural convection heat transfer of a vertical finned plate with varying the fin height and the fin spacing. In order achieve high Rayleigh numbers, an electroplating system was employed and the mass transfer rates were measured using a copper sulfate electroplating system based on the analogy concept

Live-cell calcium imaging of adherent and non-adherent GL261 cells reveals phenotype-dependent differences in drug responses.

Science.gov (United States)

Strong, Averey D; Daniels, Richard L

2017-08-02

The tumor-derived GL261 cell line is used as a model for studying glioblastoma and other high-grade gliomas, and can be cultured adherently or as free-floating aggregates known as neurospheres. These different culture conditions give rise to distinct phenotypes, with increased tumorigenicity displayed by neurosphere-cultured cells. An important technique for understanding GL261 pathobiology is live cell fluorescent imaging of intracellular calcium. However, live cell imaging of GL261 neurospheres presents a technical challenge, as experimental manipulations where drugs are added to the extracellular media cause the cells to move during analysis. Here we present a method to immobilize GL261 neurospheres with low melting point agarose for calcium imaging using the fluorescent calcium sensor fura-2. GL261 cells were obtained from the NCI-Frederick Cancer Research Tumor Repository and cultured as adherent cells or induced to form neurospheres by placing freshly trypsinized cells into serum-free media containing fibroblast growth factor 2, epidermal growth factor, and B-27 supplement. Prior to experiments, adherent cells were loaded with fura-2 and cultured on 8-well chamber slides. Non-adherent neurospheres were first loaded with fura-2, placed in droplets onto an 8-well chamber slide, and finally covered with a thin layer of low melting point agarose to immobilize the cells. Ratiometric pseudocolored images were obtained during treatment with ATP, capsaicin, or vehicle control. Cells were marked as responsive if fluorescence levels increased more than 30% above baseline. Differences between treatment groups were tested using Student's t-tests and one-way ANOVA. We found that cellular responses to pharmacological treatments differ based on cellular phenotype. Adherent cells and neurospheres both responded to ATP with a rise in intracellular calcium. Notably, capsaicin treatment led to robust responses in GL261 neurospheres but not adherent cells. We demonstrate the use

An adherence trilogy is essential for long-term HAART success

Full Text Available Adherence is the milestone of a successful therapy. Over the last decade several authors have addressed the importance of adherence for optimal results of antiretroviral (ARV therapy. Many health care systems are investing substantial resources to make available contemporary antiretroviral therapy. Despite the large investment in medications, insufficient investments have been made into an integrated adherence component to maximize the impact of these medications. Adherence, unlike drug therapy, cannot be defined as a single method with a defined prescription or formula. Instead, it is the result of a complex interaction between the patient, a prescribed medication and the health system. Many reports are available analyzing each of these components. We have found that critical elements of adherence include the patient's knowledge about the disease and how medications will help achieve a longer and healthier life, together with the motivation to adapt to a new style of life. A trilogy composed of information, motivation and behavioral skills is essential to achieve the maximum desired level of adherence. We have computerized this trilogy in a software program for self-administration in which each of the three components is provided to the patient as many times as necessary to transmit an understanding of the problem and to help make a rational decision to adhere to the ARV treatment program. In this review we analyze several efforts and techniques to improve adherence to any recommended medication that may interfere with the patient's lifestyle and outline how the adherence trilogy can be best used to optimize the ability of ARV therapy to durably suppress plasma HIV RNA to undetectable levels.

Full Text Available BACKGROUND: It has been increasingly recognized that non-adherence is an important factor that determines the outcome of peritoneal dialysis (PD therapy. There is therefore a need to establish the levels of non-adherence to different aspects of the PD regimen (dialysis procedures, medications, and dietary/fluid restrictions. METHODS: A systematic review of peer-reviewed literature was performed in PubMed, PsycINFO and CINAHL databases using PRISMA guidelines in May 2013. Publications on non-adherence in PD were selected by two reviewers independently according to predefined inclusion and exclusion criteria. Relevant data on patient characteristics, measures, rates and factors associated with non-adherence were extracted. The quality of studies was also evaluated independently by two reviewers according to a revised version of the Effective Public Health Practice Project assessment tool. RESULTS: The search retrieved 204 studies, of which a total of 25 studies met inclusion criteria. Reported rates of non-adherence varied across studies: 2.6-53% for dialysis exchanges, 3.9-85% for medication, and 14.4-67% for diet/fluid restrictions. Methodological differences in measurement and definition of non-adherence underlie the observed variation. Factors associated with non-adherence that showed a degree of consistency were mostly socio-demographical, such as age, employment status, ethnicity, sex, and time period on PD treatment. CONCLUSION: Non-adherence to different dimensions of the dialysis regimen appears to be prevalent in PD patients. There is a need for further, high-quality research to explore these factors in more detail, with the aim of informing intervention designs to facilitate adherence in this patient population.

Moitra, Ethan; Herbert, James D; Forman, Evan M

2011-12-01

A significant number of adults with HIV in the USA do not maintain adherence to highly active antiretroviral therapy (HAART) at adequate levels. Although traditional cognitive behavioral interventions have shown promise in promoting HAART adherence, acceptance-based behavior therapy (ABBT) may be particularly useful in this population. ABBT has the potential to overcome common avoidance-based barriers associated with poor adherence, including denial of various illness-related factors and avoidance of stigmatization. We describe the rationale for promoting psychological and behavioral acceptance in HIV-positive populations; outline an ABBT to promote HAART adherence targeting primary care patients from urban, minority, low socioeconomic backgrounds; and report preliminary qualitative observations of treatment feasibility and acceptability.

2015-01-01

Background With the increase in scaling up of antiretroviral therapy (ART), knowledge of the need for adherence to ART is pivotal for successful treatment outcomes. Design and Methods A cross-sectional study was carried out between October and December 2013. We administered theory of planned behaviour (TPB) and adherence questionnaires to 358 women aged 18-49 years, from a rural and urban ART-clinics in southern Malawi. Hierarchical linear regression models were used to predict intentions to adhere to ART. Results Regression models show that attitude (β=0.47), subjective norm (β=0.31) and perceived behavioural control (β=0.12) explain 55% of the variance in intentions to adhere to ART. The relationship between both food insecurity and perceived side effects with intentions to adhere to ART is mediated by attitude, subjective norm, and perceived behavioural control. Household (r=0.20) and individual (r=0.21) food insecurity were positively and significantly correlated with perceived behavioural control. Household food insecurity had a negative correlation with perceived side effects (r=-0.11). Perceived side effects were positively correlated with attitude (r=0.25). There was no statistically significant relationship between intentions to adhere to ART in the future and one month self-report of past month adherence. These interactions suggest that attitude predicted adherence only when food insecurity is high or perception of side effects is strong. Conclusions This study shows that modification might be needed when using TPB constructs in resource constraint environments. Significance for public health The knowledge of the rates of adherence to antiretroviral therapy (ART) could be used to evaluate planning and project, which could lead to better outcomes predicted by treatment efficacy data. In addition, knowledge of adherence behaviour could help the development of interventions focusing on collaboration between healthcare providers and Malawian government to

2016-01-01

Objectives: To evaluate adherence among Israeli patients who are licensed to use medical cannabis and to identify factors associated with adherence to medical cannabis. Methods: Ninety-five novice licensed patients were interviewed for this cross-sectional study. The questionnaire measured demographics, the perceived patient-physician relationship, and the level of patients' active involvement in their healthcare. In addition, patients were queried about adverse effect(s) and about their overall satisfaction from this medical treatment. Results: Eighty percent ( n =76) has been identified as adherent to medical cannabis use. Variables found associated with adherence were "country of origin" (immigrant status), "type of illness" (cancer vs. non-cancer), and "experiencing adverse effect(s)." Three predictors of adherence were found significant in a logistic regression model: "type of illness" (odds ratio [OR] 0.101), patient-physician relationship (OR 1.406), and level of patient activation (OR 1.132). 71.5% rated themselves being "completely satisfied" or "satisfied" from medical cannabis use. Conclusions: Our findings show a relatively high adherence rate for medical cannabis, as well as relative safety and high satisfaction among licensed patients. Additionally indicated is the need to develop and implement standardized education about this evolving field-to both patients and physicians.

2015-10-01

Full Text Available Background: Healthcare workers are often reluctant to start combination antiretroviral therapy (ART in patients receiving tuberculosis (TB treatment because of the fear of high pill burden, immune reconstitution inflammatory syndrome, and side-effects. Object: To quantify changes in adherence to tuberculosis treatment following ART initiation. Design: A prospective observational cohort study of ART-naïve individuals with baseline CD4 count between 50 cells/mm3 and 350 cells/mm3 at start of TB treatment at a primary care clinic in Johannesburg, South Africa. Adherence to TB treatment was measured by pill count,self-report, and electronic Medication Event Monitoring System (eMEMS before and after initiation of ART. Results: ART tended to negatively affect adherence to TB treatment, with an 8% – 10% decrease in the proportion of patients adherent according to pill count and an 18% – 22% decrease in the proportion of patients adherent according to eMEMS in the first month following ART initiation, independent of the cut-off used to define adherence (90%, 95% or 100%. Reasons for non-adherence were multi factorial, and employment was the only predictor for optimal adherence (adjusted odds ratio 4.11, 95% confidence interval 1.06–16.0. Conclusion: Adherence support in the period immediately following ART initiation could optimise treatment outcomes for people living with TB and HIV.

Treatment non-adherence in randomised trials refers to situations where some participants do not receive their allocated treatment as intended. For cluster randomised trials, where the unit of randomisation is a group of participants, non-adherence may occur at the cluster or individual level. When non-adherence occurs, randomisation no longer guarantees that the relationship between treatment receipt and outcome is unconfounded, and the power to detect the treatment effects in intention-to-treat analysis may be reduced. Thus, recording adherence and estimating the causal treatment effect adequately are of interest for clinical trials. To assess the extent of reporting of non-adherence issues in published cluster trials and to establish which methods are currently being used for addressing non-adherence, if any, and whether clustering is accounted for in these. We systematically reviewed 132 cluster trials published in English in 2011 previously identified through a search in PubMed. One-hundred and twenty three cluster trials were included in this systematic review. Non-adherence was reported in 56 cluster trials. Among these, 19 reported a treatment efficacy estimate: per protocol in 15 and as treated in 4. No study discussed the assumptions made by these methods, their plausibility or the sensitivity of the results to deviations from these assumptions. The year of publication of the cluster trials included in this review (2011) could be considered a limitation of this study; however, no new guidelines regarding the reporting and the handling of non-adherence for cluster trials have been published since. In addition, a single reviewer undertook the data extraction. To mitigate this, a second reviewer conducted a validation of the extraction process on 15 randomly selected reports. Agreement was satisfactory (93%). Despite the recommendations of the Consolidated Standards of Reporting Trials statement extension to cluster randomised trials, treatment adherence is

Research on the conceptualization of adherence to treatment has not addressed a key question: Is adherence best defined as being a uni-dimensional or multi-dimensional behavioral construct? The primary aim of this study was to test which of these conceptual models best described adherence to a weight management program. This ancillary study was conducted as a part of the POUNDS LOST trial that tested the efficacy of four dietary macro-nutrient compositions for promoting weight loss. A sample of 811 overweight/obese adults was recruited across two clinical sites, and each participant was randomly assigned to one of four macronutrient prescriptions: (1) Low fat (20% of energy), average protein (15% of energy); (2) High fat (40%), average protein (15%); (3) Low fat (20%), high protein (25%); (4) High fat (40%), high protein (25%). Throughout the first 6 months of the study, a computer tracking system collected data on eight indicators of adherence. Computer tracking data from the initial 6 months of the intervention were analyzed using exploratory and confirmatory analyses. Two factors (accounting for 66% of the variance) were identified and confirmed: (1) behavioral adherence and (2) dietary adherence. Behavioral adherence did not differ across the four interventions, but prescription of a high fat diet (vs. a low fat diet) was found to be associated with higher levels of dietary adherence. The findings of this study indicated that adherence to a weight management program was best conceptualized as being multi-dimensional, with two dimensions: behavioral and dietary adherence.

Studies have revealed that non-adherence to prescribed medication can lead to hospital readmissions, clinical complications, and other negative patient outcomes. Though many techniques have been proposed to improve patient adherence rates, they suffer from low accuracy. Our objective is to develop and test a novel system for assessment of medication adherence. Recently, several smart pill bottle technologies have been proposed, which can detect when the bottle has been opened, and even when a pill has been retrieved. However, very few systems can determine if the pill is subsequently ingested or discarded. We propose a system for detecting user adherence to medication using a smart necklace, capable of determining if the medication has been ingested based on the skin movement in the lower part of the neck during a swallow. This, coupled with existing medication adherence systems that detect when medicine is removed from the bottle, can detect a broader range of use-cases with respect to medication adherence. Using Bayesian networks, we were able to correctly classify between chewable vitamins, saliva swallows, medication capsules, speaking, and drinking water, with average precision and recall of 90.17% and 88.9%, respectively. A total of 135 instances were classified from a total of 20 subjects. Our experimental evaluations confirm the accuracy of the piezoelectric necklace for detecting medicine swallows and disambiguating them from related actions. Further studies in real-world conditions are necessary to evaluate the efficacy of the proposed scheme. Copyright © 2016 Elsevier B.V. All rights reserved.

Two character traits associated with adherence to long term therapies.

Adherence is defined as the adequacy between the behaviours of patients and their medical prescriptions. Adherence is a general behaviour, which can explain why patients in the placebo arm of randomised clinical trials have a lower mortality rate when they are adherent. We propose that this behaviour is related to two character traits: patience (capacity to give priority to the future) and, more provocatively, obedience. To support this claim, we bring arguments from the literature and from two published personal studies. We previously showed that type 2 diabetic patients who respond as non-adherers to a questionnaire on adherence to medication and to whom one proposes a fictitious monetary choice between receiving 500 euros today or waiting one year to receive 1500 euros never make the remote choice. We also showed that obese diabetic patients who declare that they do not fasten their seat belt when they are seated in the rear of a car are more often non-adherent concerning medication than those patients who claim that they follow this road safety recommendation. Thus, one of the roles of empowerment and patient education could be to encourage the patients, if they wish it, to replace passive adherence behaviours with conscious active choices.

To compare the impact of a transition coordinator on outcomes for pediatric liver transplant recipients vs a historical comparison group. To examine the utility of a transition coordinator, medication adherence, as measured by SDs of tacrolimus blood levels (Tacrolimus SD), was compared between the "transition coordinator group" (20 transplant recipients transferred between 2007 and 2012) and comparison group for 1 year before and after transfer. Measures of health care management, quality of life, and acceptability were administered to the transition coordinator group as well. A repeated measures ANOVA was used to compare adherence values between the transition coordinator group and the comparison group. During the year before transfer, for the transition coordinator group, Tacrolimus SD was 1.98 (SD = 1.05) vs 3.25 (SD = 1.19) for comparison patients, F(1,25) = 4.77, P = .04. After transfer, levels remained stable for the transition coordinator group, Tacrolimus SD = 1.88 (SD = 1.57), but increased for comparison patients, Tacrolimus SD = 4.36 (SD = 0.99), F(1,25) = 6.99, P = .01. Psychosocial outcomes remained stable during the transfer period and acceptability was high. Our findings, although limited by a small sample size, suggest that a transition coordinator is a promising method to improve this process. Copyright © 2013 Mosby, Inc. All rights reserved.

Full Text Available Gluten-related disorders are not considered of relevance at public health level in Central America. The prevalence of gluten-related disorders, and adherence to a gluten-free diet, remain unknown in the Central American region. We conducted a cross-sectional survey of the Central American population from San Salvador, El Salvador, to estimate the prevalence rates of self-reported gluten-related disorders and adherence to a gluten-free diet. 1326 individuals were surveyed. Self-reported prevalence rates were (95% Confidence Interval: gluten sensitivity 3.1% (2.3–4.2; physician-diagnosed celiac disease 0.15% (0.04–0.5; wheat allergy 0.75% (0.4–1.3; non-celiac gluten sensitivity 0.98% (0.5–1.6. The prevalence rate of adherence to a gluten-free diet was 7.0% (5.7–8.5. Seven self-reported physician diagnosed gluten-sensitive cases informed the co-existence of non-celiac gluten sensitivity with celiac disease and/or wheat allergy. Among the non-self-reported gluten sensitivity individuals following a gluten-free diet, 50% reported that they were seeing a health professional for gluten-free dietary advice. Gluten sensitivity is commonly reported in Salvadoran population, but some health professionals acknowledge the coexistence of wheat allergy, celiac disease, and non-celiac gluten sensitivity. Among studies at population level, the prevalence of adherence to a gluten-free diet in Salvadoran population is the highest reported until now. However, just a few of the gluten-free diet followers were doing it for health-related benefits; the others reported weight control and the perception that the diet is healthier as the main motivation for adopting such a diet.

Given the lifelong therapy in haemophilia patients, insight in non-adherence behaviour from a patient perspective is important to understand patients' difficulties with the following treatment recommendations. The aim of this study was to clarify the process underlying adherence (behaviour) to prophylactic treatment, from a patients' perspective. To develop a grounded theory, a qualitative study using individual in-depth interviews was performed to understand experiences, perceptions and beliefs concerning adherence to prophylaxis. From two Dutch treatment centres, 21 adults with haemophilia using prophylaxis were interviewed. Patients were asked how they experience their task to administer prophylaxis and how they adhere to this. The interviews were transcribed, coded and analysed in an iterative process, leading to the development of the grounded theory. Adherence was determined by the position of prophylaxis in life. The position of prophylaxis was determined by the perception of prophylaxis and the ability to exert prophylaxis. Patients' perception was influenced by two main factors: acceptance of haemophilia and feeling/fearing symptoms. The ability to exert prophylaxis was influenced by understanding haemophilia and prophylaxis and planning/infusion skills. The combination of different perceptions and skills led to four main positions of prophylaxis in life: (i) prophylaxis integrated in life, (ii) prophylaxis according to doctors' advice, struggling with irregular situations, (iii) prophylaxis is too much to handle, (iv) prophylaxis is a confrontation with illness. The adherence level gradually decreased from position 1 to 4. This information can be used to design tailored interventions to promote adherence. © 2015 John Wiley & Sons Ltd.

The aims of this research were to elucidate the role and extent of lateral transfer in the differentiation of bacterial strains and species, and to assess the impact of gene transfer on the evolution of bacterial genomes. The ultimate goal of the project is to examine the dynamics of a core set of protein-coding genes (i.e., those that are distributed universally among Bacteria) by developing conserved primers that would allow their amplification and sequencing in any bacterial taxa. In addition, we adopted a bioinformatic approach to elucidate the extent of lateral gene transfer in sequenced genome.

Genetic abnormalities, including chromosomal translocations, are described for many hematological malignancies. From the clinical perspective, detection of chromosomal abnormalities is relevant not only for diagnostic and treatment purposes but also for prognostic risk assessment. From the translational research perspective, the identification of fusion proteins and protein interactions has allowed crucial breakthroughs in understanding the pathogenesis of malignancies and consequently major achievements in targeted therapy. We describe the optimization of the Proximity Ligation Assay (PLA) to ascertain the presence of fusion proteins, and protein interactions in non-adherent pre-B cells. PLA is an innovative method of protein-protein colocalization detection by molecular biology that combines the advantages of microscopy with the advantages of molecular biology precision, enabling detection of protein proximity theoretically ranging from 0 to 40 nm. We propose an optimized PLA procedure. We overcome the issue of maintaining non-adherent hematological cells by traditional cytocentrifugation and optimized buffers, by changing incubation times, and modifying washing steps. Further, we provide convincing negative and positive controls, and demonstrate that optimized PLA procedure is sensitive to total protein level. The optimized PLA procedure allows the detection of fusion proteins and protein interactions on non-adherent cells. The optimized PLA procedure described here can be readily applied to various non-adherent hematological cells, from cell lines to patients' cells. The optimized PLA protocol enables detection of fusion proteins and their subcellular expression, and protein interactions in non-adherent cells. Therefore, the optimized PLA protocol provides a new tool that can be adopted in a wide range of applications in the biological field.

A Series of the turbulent mixed convective heat transfer experiments in a vertical cylinder was carried out. In order to achieve high Gr and/or Ra with small scale test rigs, the analogy concept was adopted. Using the concept, heat transfer systems were simulated by mass transfer systems, and large Grashof numbers could be achieved with reasonable facility heights. The tests were performed with buoyancy-aided flow and opposed flow for Reynolds numbers from 4,000 to 10,000 with a constant Grashof number, Gr H of 6.2 x 10 9 and Prandtl number of about 2,000. The test results reproduced the typical of the mixed convection heat transfer phenomena in a turbulent situation and agree well with the experimental study performed by Y. Palratan et al. The analogy experimental method simulated the mixed convection heat transfer phenomena successfully and seems to be a useful tool for heat transfer studies for VHTR as well as the systems with high buoyancy condition and high Prandtl number

Study Objectives: Adolescents with obstructive sleep apnea syndrome (OSAS) represent an important but understudied subgroup of long-term continuous positive airway pressure (CPAP) users. The purpose of this qualitative study was to identify factors related to adherence from the perspective of adolescents and their caregivers. Methods: Individual open-ended, semi-structured interviews were conducted with adolescents (n = 21) and caregivers (n = 20). Objective adherence data from the adolescents' CPAP machines during the previous month was obtained. Adolescents with different adherence levels and their caregivers were asked their views on CPAP. Using a modified grounded theory approach, we identified themes and developed theories that explained the adolescents' adherence patterns. Results: Adolescent participants (n = 21) were aged 12-18 years, predominantly male (n = 15), African American (n = 16), users of CPAP for at least one month. Caregivers were mainly mothers (n = 17). Seven adolescents had high use (mean use 381 ± 80 min per night), 7 had low use (mean use 30 ± 24 min per night), and 7 had no use during the month prior to being interviewed. Degree of structure in the home, social reactions, mode of communication among family members, and perception of benefits were issues that played a role in CPAP adherence. Conclusions: Understanding the adolescent and family experience of using CPAP may be key to increasing adolescent CPAP adherence. As a result of our findings, we speculate that health education, peer support groups, and developmentally appropriate individualized support strategies may be important in promoting adherence. Future studies should examine these theories of CPAP adherence. Citation: Prashad PS; Marcus CL; Maggs J; Stettler N; Cornaglia MA; Costa P; Puzino K; Xanthopoulos M; Bradford R; Barg FK.

Impairment in cognitive function is found in a significant subset of individuals undergoing bariatric surgery, and recent work shows this impairment is associated with smaller postoperative weight loss. Reduced cognitive function could contribute to poorer adherence to postoperative guidelines, although this has not been previously examined. The present study examined the relationship between cognitive function and adherence to bariatric postoperative guidelines. We expected that higher cognitive function would be associated with better adherence to postoperative guidelines. Thirty-seven bariatric surgery patients completed cognitive testing and a self-report measure of adherence to postoperative bariatric guidelines during their 4- to 6-week postoperative appointment. Strong correlations were observed between adherence to postoperative guidelines and cognitive indices of attention, executive function, and memory. Results show that cognitive performance is strongly associated with adherence to postoperative guidelines shortly after bariatric surgery. Further work is needed to clarify whether this relationship is present at later postoperative stages and the degree to which this relationship mediates postoperative weight loss outcomes.

While adherence to medication in smoking cessation clinical trials is strongly associated with clinical outcome, very few studies have evaluated the validity of pill count as a measure of adherence relative to a biological assay, and evaluated a broad range of correlates of adherence. In a smoking cessation clinical trial of varenicline, we compared pill counts collected over 4 different time periods to varenicline salivary levels taken after 2weeks of treatment, as well as evaluated predictors of adherence to varenicline. Using a binary measure of adherence based on salivary varenicline levels, adherence was higher among older, white, and more educated participants. Relative to 3, 7, and 14-day pill count, 12-week pill count was the only significant measure able to discriminate adherence as defined by salivary varenicline levels (assessed by area under the receiver operating characteristic curve; AUC=0.59, p=0.004). Seventy-two percent of participants who indicated adherence on 12-week pill count were classified as adherent based on varenicline saliva levels (sensitivity=0.80; specificity=0.40). There was modest variability in the relationship between 12-week pill count and varenicline levels across race and rate of nicotine metabolism. Lastly, General Estimating Equation models demonstrated that longitudinal changes in withdrawal, craving, negative and positive affect, and side effect count and severity were not related to adherence based on salivary varenicline levels. These results indicate that 12-week pill count was the best, albeit a relatively weak, measure of varenicline adherence; additional factors associated with treatment adherence need to be identified.

Full Text Available Jose Manuel Montes1, Jorge Maurino2, Consuelo de Dios3, Esteban Medina21Department of Psychiatry, Hospital Universitario del Sureste, 2AstraZeneca Medical Department, 3Department of Psychiatry, Hospital Universitario La Paz, Madrid, SpainBackground: The primary aim of this study was to assess drug treatment adherence in patients with bipolar disorder and to identify factors associated with adherence. The secondary aim was to analyze the impact of suboptimal adherence on clinical and functional outcomes.Methods: A cross-sectional study was conducted in a sample of outpatients receiving an oral antipsychotic drug. Medication adherence was assessed combining the 10-item Drug Attitude Inventory, the Morisky Green Adherence Questionnaire, and the Compliance Rating Scale. Logistic regression was used to determine significant variables associated with suboptimal adherence to medication.Results: Three hundred and three patients were enrolled into the study. The mean age was 45.9 ± 12.8 years, and 59.7% were females. Sixty-nine percent of patients showed suboptimal adherence. Disease severity and functioning were significantly worse in the suboptimal group than in the adherent group. Multivariate analysis showed depressive polarity of the last acute episode, presence of subsyndromal symptoms, and substance abuse/dependence to be significantly associated with suboptimal treatment adherence (odds ratios 3.41, 2.13, and 1.95, respectively.Conclusion: A high prevalence of nonadherence was found in an outpatient sample with bipolar disorder. Identification of factors related to treatment adherence would give clinicians the opportunity to select more adequately patients who are eligible for potential adherence-focused interventions.Keywords: bipolar disorder, treatment adherence, functioning, polarity, subsyndromal symptoms

Children with Autism Spectrum Disorder (ASD) participate in a variety of treatments, including medication, behavioral, alternative and developmental treatments. Parent adherence to these treatments is crucial for positive child outcomes. The current study: 1) Explored patterns of parent adherence across the full range of treatments that are prescribed to children with ASD and, 2) Examined whether parent demographics, parent treatment attitudes, and child ASD severity contribute to parents' adherence across ASD treatments. Questionnaires were distributed to parents of children with ASD in a southeastern state. Parents (N = 274) were included if they were parenting a child with ASD who was receiving treatment for ASD symptoms. Paired t-tests and multiple linear regression were used to assess the study aims. Adherence to medication treatment was significantly greater than adherence to behavioral, developmental, or alternative treatments (adjusted p-values 0.0006, 0.0030, 0.0006 respectively). Perceived family burden of a treatment was associated with lower adherence to medication, developmental, and alternative treatments. Finally, greater ASD severity was associated with lower adherence to alternative treatments. Overall, the independent variables accounted for more variance in adherence to medication and alternative treatments than in behavioral and developmental treatments. Parents' adherence to ASD treatment differs significantly by treatment type and is influenced by parental perceptions of the burden of treatment on the family. These findings highlight the importance of understanding and addressing the impact of ASD treatment regimens on family life. Copyright © 2015 Elsevier Inc. All rights reserved.

Psychosocial Variables Associated with Immunosuppressive Medication Non-Adherence after Renal Transplantation

Full Text Available IntroductionNon-adherence to immunosuppressive medication is regarded as an important factor for graft rejection and loss after successful renal transplantation. Yet, results on prevalence and relationship with psychosocial parameters are heterogeneous. The main aim of this study was to investigate the association of immunosuppressive medication non-adherence and psychosocial factors.MethodsIn 330 adult renal transplant recipients (≥12 months posttransplantation, health-related quality of life, depression, anxiety, social support, and subjective medication experiences were assessed, and their associations with patient-reported non-adherence was evaluated.Results33.6% of the patients admitted to be partially non-adherent. Non-adherence was associated with younger age, poorer social support, lower mental, but higher physical health-related quality of life. There was no association with depression and anxiety. However, high proportions of clinically relevant depression and anxiety symptoms were apparent in both adherent and non-adherent patients.ConclusionIn the posttransplant follow-up, kidney recipients with lower perceived social support, lower mental and higher physical health-related quality of life, and younger age can be regarded as a risk group for immunosuppressive medication non-adherence. In follow-up contacts with kidney transplant patients, physicians may pay attention to these factors. Furthermore, psychosocial interventions to optimize immunosuppressive medication adherence can be designed on the basis of this information, especially including subjectively perceived physical health-related quality of life and fostering social support seems to be of importance.
