RESUMO

BACKGROUND: U.S. cancer patients engage in administrative tasks to pay for their healthcare. This study investigated the relationship between payment tasks and timely access to cancer care. METHODS: We analyzed online survey data from 510 U.S. cancer patients and survivors to understand the relationship between administrative payment tasks and cost-related delays and nonadherence. Two-part modelling was used to determine if, and to what extent, there was a relationship between administrative burden and cost-related delays/nonadherence. RESULTS: Younger patients (≤44 years) reported more payment tasks and cost-related delays/nonadherence than older patients (≥ 55 years); African American patients reported more payment tasks and cost-related delays/nonadherence than white patients. After accounting for age, race/ethnicity, education, and out-of-pocket costs, patients who reported engaging in more tasks had greater log odds of delaying/forgoing care [b = 0.18; 95% confidence interval (CI), 0.12-0.24]. Cost-related delays/nonadherence increased by 32% for every unit increase in administrative payment burden (b = 0.32; 95% CI, 0.18-0.46). CONCLUSIONS: Administrative payment burden increased the odds of cost-related delays and nonadherence by 49%, taking the form of delayed or skipped doctor appointments, tests and bloodwork, and prescription fulfillment. Younger patients and those identifying as African American were more likely to engage in payment tasks and to delay or forgo care due to cost. Administrative burdens can disrupt access to care and traditionally underserved patient populations are disproportionately exposed to these hardships. IMPACT: Reducing the complexity of healthcare through universal, human-centered design could reduce burdens and increase access.

RESUMO

Palliative care has demonstrated effectiveness in alleviating the biological, emotional, social, and spiritual symptoms that accompany serious illness, and improving quality of life for seriously ill individuals and their family members. Despite increasing availability, there are significant disparities in access to and utilization of palliative care, particularly among diverse, low-income, and community-dwelling older adults with chronic illness. Training frontline service providers is a novel approach to expanding access to palliative care among underserved elders. This article presents a process and outcome evaluation of a palliative care curriculum that was developed and piloted for geriatric case managers in a large urban area. We describe the background, planning, design, implementation, and preliminary outcomes associated with a pilot implementation of the curriculum. We conclude with implications for replicating efforts to enhance frontline providers' knowledge, skills, and self-efficacy in extending palliative care to communities that lack access to critical supports for their burdensome symptoms.

RESUMO

To improve the metabolic stability profile of BMS-741672 (1a), we undertook a structure-activity relationship study in our trisubstituted cyclohexylamine series. This ultimately led to the identification of 2d (BMS-753426) as a potent and orally bioavailable antagonist of CCR2. Compared to previous clinical candidate 1a, the tert-butyl amine 2d showed significant improvements in pharmacokinetic properties, with lower clearance and higher oral bioavailability. Furthermore, compound 2d exhibited improved affinity for CCR5 and good activity in models of both monocyte migration and multiple sclerosis in the hCCR2 knock-in mouse. The synthesis of 2d was facilitated by the development of a simplified approach to key intermediate (4R)-9b that deployed a stereoselective reductive amination which may prove to be of general interest.

RESUMO

Although palliative care (PC) has become increasingly familiar, considerable gaps persist in access to and use of services. Community-based programs remain rare, and low-income, minority communities significantly under-utilize hospice and palliative services. We used community-based participatory research (CBPR) methods to conduct a mixed-methods community needs assessment of seriously-ill older adults (n=100) and providers from community-based programs and churches (n=41) in an urban medically-underserved community in the U.S. to explore: (I) the prevalence and severity of illness-related symptoms and psychosocial-spiritual concerns; (II) the scope and quality of community supports helping older adults manage their symptoms; and (III) the perceptions and utilization of palliative and supportive care services among older adults and community-based service providers. Participants reported high rates of chronic illness-related symptoms (i.e., pain, fatigue, sleeping difficulties, depression, and anxiety), and many described unmet needs around symptom management. Few had ever utilized PC or pain management services, and most relied primarily on family, friends, and faith communities to help them manage burdensome symptoms. Barriers included lack of familiarity with PC, limited access and financial concerns. Older adults were largely unfamiliar with PC, and many described unmet needs and desire for help with symptom burden. Findings support the need to further explore community-level and cultural barriers to PC among diverse, underserved older adults. Development of innovative community partnerships may help raise awareness of PC and address the physical and psychosocial-spiritual challenges facing chronically-ill minority older adults and their families.

RESUMO

We encountered a dilemma in the course of studying a series of antagonists of the G-protein coupled receptor CC chemokine receptor-2 (CCR2): compounds with polar C3 side chains exhibited good ion channel selectivity but poor oral bioavailability, whereas compounds with lipophilic C3 side chains exhibited good oral bioavailability in preclinical species but poor ion channel selectivity. Attempts to solve this through the direct modulation of physicochemical properties failed. However, the installation of a protonation-dependent conformational switching mechanism resolved the problem because it enabled a highly selective and relatively polar molecule to access a small population of a conformer with lower polar surface area and higher membrane permeability. Optimization of the overall properties in this series yielded the CCR2 antagonist BMS-741672 (7), which embodied properties suitable for study in human clinical trials.

RESUMO

OBJECTIVES:: A sizable minority of those who lose a loved one in hospice will experience symptoms of bereavement-related mental health disorders. Though hospices offer services to bereaved informal caregivers (family members or friends) of patients, little is known about services offered or interest in them. Therefore, we sought to assess services offered by hospice staff and interest expressed by bereaved informal caregivers with symptoms of depression, anxiety, or complicated grief (CG). METHODS:: De-identified electronic bereavement care charts of 3561 informal caregivers who lost someone in a large urban metropolitan hospice from October 1, 2015, to June 30, 2016, were reviewed. RESULTS:: Of bereaved informal caregivers in the sample, 9.4% (n = 333) were positive for symptoms of depression, anxiety, or CG. The symptom-positive family members/friends were more likely than other family members/friends to be offered mailings, one-to-one counseling, telephone calls, and reference material. However, interest in most services by symptom-positive caregivers was low, with only 6% interested in one-to-one counseling and 7% interested in outside referral. DISCUSSION:: The findings suggest that hospices offer a range of services to family members or friends with symptoms of anxiety, depression, and CG, but that there can be a gap between what is offered and in the interest levels of the bereaved. Engagement with symptomatic family members and friends could be enhanced in future work.

RESUMO

Although they experience high rates of chronic illness, low-income minority communities have traditionally underutilized palliative care services compared to whites and those with higher incomes. One reason for this trend is lack of screening by community providers. We utilized a community-based participatory research approach to develop and implement an innovative multidomain palliative care screening tool in aging service agencies. Participants were aging service providers and clients in the East and Central Harlem neighborhoods of New York City, which are characterized by high poverty, largely African American and Latino populations, disproportionally high rates of chronic conditions, and limited health-care access. Screening tool development included reviewing existing measures and obtaining feedback from an expert panel, aging service providers, and older adults. We developed a 22-item tool covering 3 domains of palliative care need (physical symptoms, emotional concerns, and goals of care), which can be administered in 10 to 15 minutes. Sixteen providers at 2 aging service agencies were trained to use the tool over a 3-month pilot period. The tool showed evidence of feasibility of implementation, with 44 older adult clients screened. Providers reported high acceptability, 36% of clients screened positive, and the majority accepted referrals to outpatient palliative care clinics. The screening tool has the potential to increase palliative care utilization among underserved community-dwelling older adults and may improve their quality of life, potentially in communities worldwide. Future work should examine the psychometric proprieties of the tool, examine predictors of positive screens, explore its impact on clinical outcomes, and expand its reach.

RESUMO

As Americans live longer with chronic illnesses, there is a growing need for social workers with the knowledge and skills to deliver quality palliative care to older adults and their families. Nevertheless, there remains a critical shortage of social workers prepared to provide quality palliative and end-of-life care (PELC) and to maintain the field into the next generation. Formal mentorship programs represent an innovative approach to enhancing practice, providing support and guidance, and promoting social work leadership in the field. This article reviews the literature on mentorship as an approach to professional and leadership development for emerging social workers in PELC. The Zelda Foster Studies Program in Palliative and End-of-Life Care bolsters competencies and mentors social workers in PELC over the trajectory of their careers, and enhances the capacity in the field. Findings from the first six years of two components of the ZF Program are examined to illustrate the feasibility, benefits, and challenges of formal mentorship programs. The authors describe the background, structure, and evaluation of the initiative's mentorship programs, and discuss the implications of mentorship in PELC for social work education, practice, and research.

RESUMO

A series of compounds which exhibited good human CCR1 binding and functional potency was modified resulting in the discovery of a novel series of high affinity, functionally potent antagonists of the CCR1 receptor. Issues of PXR activity, ion-channel potency, and poor metabolic stability were addressed by the addition of a hydroxyl group to an otherwise lipophilic area in the molecule resulting in the discovery of preclinical candidate BMS-457 for the treatment of rheumatoid arthritis.

RESUMO

Although social work has a long and distinctive tradition of practice-relevant research aimed at enhancing the health and well-being of older adults, the profession has been underrepresented among the ranks of academic researchers and the National Institutes of Health's (NIH) scientific endeavors. In this article, the inherent capacities of social workers to generate and disseminate empirical health-related knowledge are discussed and recent developments in social work's geriatric research infrastructure are described. Emerging domains for advancing the profession's contribution to practice-relevant geriatric research on the federal level are identified and the next steps toward advancing the field's research agenda are posed.

RESUMO

Family narratives of genetic disease address multigenerational legacies of illness, guide expectations about future diagnoses and anticipated losses, and promote continuity and coherence. Yet contemporary families with histories of genetic disease face the challenge of integrating long-standing family illness narratives with technological advances in the detection and treatment of the identified disease. The authors recommend the use of narrative methods to (a) integrate multiple or competing perspectives into a comprehensive story of the illness experience, (b) accommodate historically based illness narratives to modern technological advances that enable novel trajectories, and (c) identify pathways to sustained physical and mental health through enhanced medical decision making. A case example illustrates the use of a medical genogram to track patterns of illness expression and narrative construction over multiple generations, and implications for family therapy and research are discussed.

RESUMO

The purpose of the study was to evaluate how participation in the CareLink program influenced the community health knowledge and skill of baccalaureate nursing students regarding the care of community-dwelling older adults. Students were assigned three to four clients each during their 14-week clinical placement with a home care agency, situated in a naturally occurring retirement community or senior center. Students contracted with their clients to set goals and provided standardized health assessments and teaching. Students completed pretest and posttest surveys, and attended focus groups to address their learning. Students' public health nursing and cultural competence improved significantly. The CareLink program provides a meaningful learning experience for baccalaureate nursing students. Attitudes toward older adults and community health nursing in general shifted to acknowledge that older adults have strengths and resilience not previously acknowledged.

RESUMO

This study examined the end-of-life challenges, concerns, and care preferences of terminally ill elders and their family caregivers, with a focus on areas of congruence and incongruence. Ten elders and 10 family caregivers participated in separate, semi-structured, face-to-face interviews. Data analysis included team coding and thematic analysis, guided by an a priori set of categories based on the study questions. Shared challenges and concerns included experiencing decline, managing pain and discomfort, and living with uncertainty. There was also congruence regarding end-of-life care preferences, specifically the importance of quality care, treatment with dignity and respect, and avoiding unnecessary life-sustaining treatment. Areas of incongruence included the elders' difficulties in accepting dependence, their fears of becoming a burden, and desire to be prepared for death. Family caregivers were most concerned with providing adequate care to meet the elders' physical and spiritual care needs. Open family communication was associated with greater congruence. The authors discuss implications of these findings for research and intervention.

RESUMO

Ambiguity in the dying experience can be a major source of stress for older couples who must often balance the provision of care with respect for autonomy, aggressive treatment with quality-of-life, and individual with dyadic understandings and preferences. This study explores patterns of relationship, support, and communication in married or partnered couples where one partner is diagnosed with advanced and terminal cancer. Thirty-five older spousal/partner dyads participated in focused, semistructured interviews about relational aspects of their illness experiences. Faced with often uncertain and ambiguous circumstances, cancer patients and their partner caregivers describe the individual and dyadic processes that they have engaged in as they approach the end of life. Implications are highlighted for future research and practice with older adult couples at the end of life.

RESUMO

Conformational analysis of the 3-benzylpiperidine in CCR3 antagonist clinical candidate 1 (BMS-639623) predicts that the benzylpiperidine may be replaced by acyclic, conformationally stabilized, anti-1,2-disubstituted phenethyl- and phenpropylamines. Ab initio calculations, enantioselective syntheses, and evaluation in CCR3 binding and chemotaxis assays of anti-1-methyl-2-hydroxyphenethyl- and phenpropylamine-containing CCR3 antagonists support this conformational correlation.

RESUMO

Conformational analysis of trans-1,2-disubstituted cyclohexane CCR3 antagonist 2 revealed that the cyclohexane linker could be replaced by an acyclic syn-alpha-methyl-beta-hydroxypropyl linker. Synthesis and biological evaluation of mono- and disubstituted propyl linkers support this conformational correlation. It was also found that the alpha-methyl group to the urea lowered protein binding and that the beta-hydroxyl group lowered affinity for CYP2D6. Ab initio calculations show that the alpha-methyl group governs the spatial orientation of three key functionalities within the molecule. alpha-Methyl-beta-hydroxypropyl urea 31 with a chemotaxis IC(50)=38 pM for eosinophils was chosen to enter clinical development for the treatment of asthma.

RESUMO

Starting with our previously described(20) class of CC chemokine receptor-3 (CCR3) antagonist, we improved the potency by replacing the phenyl linker of 1 with a cyclohexyl linker and by replacing the 4-benzylpiperidine with a 3-benzylpiperidine. The resulting compound, 32, is a potent and selective antagonist of CCR3. SAR studies showed that the 3-acetylphenyl urea of 32 could be replaced with heterocyclic ureas or heterocyclic-substituted phenyl ureas and still maintain the potency (inhibition of eotaxin-induced chemotaxis) of this class of compounds in the low-picomolar range (IC(50) = 10-60 pM), representing some of the most potent CCR3 antagonists reported to date. The potency of 32 for mouse CCR3 (chemotaxis IC(50) = 41 nM) and its oral bioavailability in mice (20% F ) were adequate to assess the efficacy in animal models of allergic airway inflammation. Oral administration of 32 reduced eosinophil recruitment into the lungs in a dose-dependent manner in these animal models. On the basis of its overall potency, selectivity, efficacy, and safety profile, the benzenesulfonate salt of 32, designated DPC168, entered phase I clinical trials.
