Background: Despite the need for hospice care as our society ages, adults in the U.S.'s southern rural region have limited awareness of hospice care. Objective: This study aims to assess the rate of awareness of hospice care among rural residents living in Alabama's Black Belt region and examine social determinants of health (SDH) associated with the awareness. Methods: A cross-sectional survey was conducted among a convenience sample living in Alabama's Black Belt region (N = 179, age = 18-91). Participants' awareness of hospice care, demographic characteristics (ie, age and gender), and SDH (ie, financial resources strain, food insecurity, education and health literacy, social isolation, and interpersonal safety) were assessed. Lastly, a binary logistic regression was used to examine the association between SDH and hospice awareness among participants while controlling for demographic characteristics. Results: The majority of participants had heard of hospice care ( n = 150, 82.1% ), and older participants (50 years old or older) were more likely to report having heard of hospice care ( OR = 7.35, P < 0.05). Participants reporting worries about stable housing (OR = 0.05, P < 0.05) and higher social isolation were less likely to have heard of hospice care ( OR = 0.53, P < 0.05), while participants with higher health literacy had a higher likelihood to have heard of it ( OR = 2.60, P < 0.01). Conclusions: Our study is the first study assessing the status of hospice awareness among residents of Alabama's Black Belt region. This study highlighted that factors including age and certain SDH (ie, housing status, health literacy, and social isolation) might be considered in the intervention to improve hospice awareness.

Background: Pain and symptom management is critical in ensuring quality of life for chronically ill older adults. However, while pain management and palliative care have steadily expanded in recent years, many underserved populations, such as rural older adults, experience barriers in accessing such specialty services, in part due to transportation issues. The purpose of this systematic review is to examine the specific types of transportation-related barriers experienced by rural older adults in accessing pain and palliative care., Methods: Studies were searched through the following 10 databases: Abstracts in Social Gerontology, Academic Search Premier, CINAHL, MEDLINE, PsycINFO, SocINDEX with Full Text, Cochrane Database of Systematic Reviews, Nursing & Allied Health Database, Sociological Abstracts, and PubMED. Studies were chosen for initial review if they were written in English, full text, included older adults in the sample, and examined pain/palliative care/hospice, rural areas, and transportation. A total of 174 abstracts were initially screened, 15 articles received full-text reviews and 8 met the inclusion criteria., Results: Findings of the 8 studies identified transportation-related issues as major access barrier to pain and palliative care among rural older adults: specifically, lack of public transportation; lack of wheelchair accessible vehicles; lack of reliable drivers; high cost of transportation services; poor road conditions; and remoteness to the closest pain and palliative care service providers., Conclusion: Results suggest that rural older adults have unique transportation needs due to the urban-centric location of pain and palliative care services. Implications for practice, policy and research with older adults are discussed.

Associations of perceived health and social and physical activities with end-of-life (EOL) issues have been rarely studied, not to mention racial disparities in such associations. To address this gap, this study examined racial differences in the associations of perceived health and levels of social and physical activities with advance care planning, EOL concerns, and knowledge of hospice care among community-dwelling older adults in Alabama. Data from a statewide survey of 1044 community-dwelling older adults on their long-term care needs were analyzed using descriptive statistics and logistic and linear regressions. Results showed that black older adults were less likely to know about or document advance care planning and to have accurate knowledge of hospice care; however, despite their poorer perceived health, black older adults reported fewer EOL concerns. Higher levels of perceived health and social and physical activities were associated with knowledge about advance care planning among white older adults but not among black older adults. Both black and white older adults with poorer perceived health and lower levels of social and physical activities tended to have more EOL concerns and less knowledge of hospice care. These findings suggest that interventions to address suboptimal levels of perceived health and social and physical activities among black older adults may increase knowledge of advance care planning. Also, supportive services to address EOL concerns should be targeted at older adults with poorer perceived health and limited participation in social and physical activities.

The underuse of hospice care by terminally ill African American elders suggests they are suffering when hospice care could offer quality end of life care. Guided by the Behavioral Model for Vulnerable Populations, this study sought understanding of structural barriers faced when seeking access to hospice care and reasons for using it when access is possible. Data was collected through interviews with 28 African American hospice patients. Themes from directed content analysis provide insights into strategies used to overcome access barriers posed by income, health insurance and administrative procedure, as well as the role religion, family, information and health beliefs played in using it. Distributing educational materials and addressing spiritual/religious concerns in choosing hospice care are key in promoting African Americans' use of hospice care., (© The Author(s) 2014.)

The survival of patients with end-stage renal disease (ESRD) resulting from diabetes continues to improve, but the survival rate among diabetic ESRD patients remains the lowest among all primary diagnoses probably because of the higher prevalence of cardiovascular comorbidity associated with diabetes. Diabetes, age, and comorbidity all significantly modify the effect of treatment modality on patient survival. As compared with hemodialysis (HD), peritoneal dialysis (PD) offers an equal or lower risk of death across all subgroups during the first 1-2 years of dialysis. The association of PD with better outcomes than are seen with HD is probably a result of a lower prevalence of infections and congestive heart failure and better preservation of residual renal function (RRF) in PD patients. Use of angiotensin converting-enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) helps to preserve RRF in ESRD patients and to maintain peritoneal membrane integrity longer in PD patients. Antioxidants can also support preservation of peritoneal membrane function. Peritoneal dialysis should be the initial modality of dialysis in all ESRD patients. Older patients (age > or = 45 years) with diabetes and patients without diabetes may switch to HD or receive a kidney graft in 1-2 years' time; younger patients (age < 45 years) with diabetes may stay on PD longer. Use of ACEI and ARB or antioxidants can help to maintain peritoneal membrane function longer.

Objective: To demonstrate the presence of an independent renin-angiotensin system (RAS) in the peritoneum and to determine the role of locally produced angiotensin (Ang) II in high glucose-induced upregulation of transforming growth factor (TGF)-beta1 and fibronectin by human peritoneal mesothelial cells (HPMC)., Methods: In cultured HPMC, the expression of mRNAs for angiotensinogen, angiotensin-converting enzyme (ACE), Ang II type 1 receptor (AT1), and TGF-beta1 was evaluated by real-time polymerase chain reaction; ACE, AT1, and fibronectin proteins by Western blot analysis; and Ang I, Ang II, and TGF-beta1 proteins by ELISA. Dichlorofluorescein (DCF)-sensitive cellular reactive oxygen species (ROS) were measured by fluorometry., Results: HPMC constitutively expressed all the components of RAS, and 50 mmol/L D-glucose (high glucose) significantly increased angiotensinogen, ACE, and AT1 mRNAs and ACE, AT1, and Ang II proteins. Ang II increased TGF-beta1 and fibronectin protein expression and DCF-sensitive cellular ROS. Losartan prevented Ang II-induced increase in cellular ROS. Both losartan and captopril inhibited high glucose-induced upregulation of TGF-beta1 and fibronectin expression in HPMC in a dose-dependent manner. Antioxidant catalase and NADPH oxidase inhibitor diphenyleneiodinium effectively inhibited Ang II-induced TGF-beta1 and fibronectin protein expression., Conclusions: The present data demonstrate that HPMC constitutively express RAS, that Ang II produced by HPMC mediates high glucose-induced upregulation of TGF-beta1 and fibronectin expression, and that Ang II-induced TGF-beta1 and fibronectin expression in HPMC is mediated by NADPH oxidase-dependent ROS. These data suggest that locally produced Ang II and ROS in the peritoneum may be potential therapeutic targets in peritoneal fibrosis during long-term peritoneal dialysis.
