Describing the characteristics and symptom profile of a group of urban patients experiencing socioeconomic inequity and receiving palliative care: a descriptive exploratory analysis.

Background: Individuals experiencing socioeconomic inequity have worse health outcomes and face barriers to palliative and end-of-life care. There is a need to develop palliative care programs tailored to this underserved population. Objectives: To understand the characteristics and symptom profiles of a group of urban patients experiencing socioeconomic inequity and receiving palliative care. Design: Descriptive exploratory analysis of a patient dataset. The patient dataset was generated through a pilot research study with patients experiencing socioeconomic inequity and life-limiting illness who received a community-based palliative care intervention. Methods: The intervention took place over 1 year in the Palliative Care Outreach and Advocacy Team, a community-based urban palliative care clinic in Edmonton, Alberta, Canada, serving persons experiencing socioeconomic inequity. Participants had to be at least 18 years of age, be able to communicate in English, require palliative care for a life-limiting illness, and be able to consent to inclusion in the study. Results: Twenty-five participants were enrolled. Participants predominantly identified as male and Indigenous, experienced poverty and housing instability, and had metastatic cancer. Our participants rated their pain, shortness of breath, and anxiety as more severe than the broader community-based palliative care population in the same city. Most patients died in inpatient hospices (73%). Conclusion: Our analysis provides an in-depth picture of an understudied, underserved population requiring palliative care. Given the higher symptom severity experienced by participants, our analysis highlights the importance of person-centered palliative care. We suggest that socioeconomic inequity should be considered in patients with life-limiting illnesses. Further research is needed to explore palliative care delivery to those facing socioeconomic inequity.

The impact of socioeconomic inequality on access to health care for patients with advanced cancer: A qualitative study.

Objective: In Canada, populations experiencing socioeconomic inequality have lower rates of access to screening and diagnosis and higher mortality rates than people from higher-income areas. Limited evidence exists concerning their experiences when living with advanced cancer. We explored how socioeconomic inequality shapes the experiences of patients with advanced cancer. Methods: We utilized a qualitative study design that combined tenets of hermeneutic phenomenological inquiry and critical theory. Four individuals with advanced cancer from low-income neighborhoods, three family members, and six cancer care providers were accrued through a tertiary cancer center in a western Canadian city. One-on-one interviews and brief notes were used for data collection. Data were analyzed through thematic analysis. Results: Three interrelated themes were identified: 'Lack of access to socioeconomic supports,' 'Gaps in access to health care resources and services,' and 'Limited access to symptom relief.' Patients experienced inadequate finances, housing, and transportation. Most patients lived alone and had limited family and social support. Patients reported lack of knowledge of available resources and health system navigation issues, including communication problems with providers and among levels of care. Cancer care providers and patients described issues achieving symptom relief as well as challenges associated with extensive disease. Conclusions: Study findings suggest that socioeconomic inequality interferes with the ability of persons with advanced cancer to access health care and contributes to less optimal cancer outcomes. Socioeconomic inequality may increase symptom severity. Findings call for the development of tailored interventions for populations with advanced cancer and socioeconomic inequality.

Inequities in access to palliative and end-of-life care in the black population in Canada: a scoping review.

BACKGROUND: Improving equity and early access to palliative care for underserved populations in Canada is a priority. Little is known regarding access to palliative and end-of-life care in the Black population. METHODS: We undertook a scoping review using the framework by Arksey and O'Malley to identify knowledge, access gaps, and experiences of palliative and end-of-life care among Blacks living with life-limiting illnesses in Canada. Primary studies, discussion papers, books, and reports were considered eligible. We followed a comprehensive search strategy developed by an information scientist. Searches were performed in the following bibliographic databases: Medline, EMBASE, PsycINFO via OVID, CINAHL via EBSCOhost, Scopus and Cochrane Library via Wiley. The search strategy was derived from three main concepts: (1) Black people; (2) Canada and Canadian provinces; (3) Palliative, hospice, or end-of-life care. No publication date or language limits were applied. Titles and abstracts were screened for eligibility by one reviewer and full text by two independent reviewers. RESULTS: The search yielded 233 articles. Nineteen articles were selected for full-text review, and 7 articles met the inclusion criteria. These studies were published between 2010 and 2021, and conducted in the provinces of Ontario and Nova Scotia only. Studies used both quantitative and qualitative methods and included cancer decedents, next of kin, family caregivers and religious leaders. Sample sizes in various studies ranged from 6 - 2,606 participants. Included studies reported a general lack of understanding about palliative and end-of-life care, positive and negative experiences, and limited access to palliative and end-of-life care for Blacks, across all care settings. CONCLUSION: Findings suggest limited knowledge of palliative care and inequities in access to palliative and end-of-life care for Blacks living with life-limiting illnesses in 2 Canadian provinces. There is an urgent need for research to inform tailored and culturally acceptable strategies to improve understanding and access to palliative care and end-of-life care among Blacks in Canada.

Examining the Contemporary Use of Hospitals in Canada for Palliative Care Purposes: A Population-Based Study to Enable Policy and Program Developments.

Background: It is commonly thought that most deaths in developed countries take place in hospital. Death place is a palliative care quality indicator. Objectives: To determine the use of Canadian hospitals by patients who died in hospital during the 2019-2020 year and any additional hospital utilization occurring over their last 365 days of life. Design: An investigation of population-based (2018-2020) Canadian hospital data using SAS. Settings/Subjects: All patients admitted to hospital and discharged alive or deceased. Measurements: Describe patients who died in hospital, and any additional use of hospitals by these patients over their last year of life. Results: Ninety-one thousand six hundred forty inpatients died during 2019-2020; 4.85% of all 1.88 million hospitalized individuals and 41.82% of all deaths in Canada that year. Decedents were primarily 65+ years of age (81.16%), male (53.44%), admitted through an emergency department (80.16%), and arrived by ambulance (72.15%). The most common diagnosis was the nonspecific ICD-10 defined "factors influencing health status and contact with health services" (23.75%), followed by "circulatory diseases" (18.22%), "respiratory diseases" (15.58%), and many other less common diagnoses. The average length of final hospital stay was 16.54 days, with 89.97% having some Alternative Level of Care (ALC) or ALC days recorded, indicating another care setting was preferable. Only 5.78% had cardiopulmonary resuscitation performed during their final hospitalization. Of all 91,640 decedents, 74.33% had only one admission to hospital in their last 365 days of life, while 25.67% (more often younger than older decedents) had two to five admissions. Conclusions: This study confirms a continuing shift of death and dying out of hospital in Canada. Most deaths and end-of-life care preceding death take place outside of hospitals now. Enhanced community-based services are recommended to support optimal dying processes outside of hospitals and also help more dying people avoid hospital deaths.

Increasing access to palliative care for patients with advanced cancer of African and Latin American descent: a patient-oriented community-based study protocol.

BACKGROUND: Cancer disparities are a major public health concern in Canada, affecting racialized communities of Latin American and African descent, among others. This is evident in lower screening rates, lower access to curative, and palliative-intent treatments, higher rates of late cancer diagnoses and lower survival rates than the general Canadian population. We will develop an Access to Palliative Care Strategy informed by health equity and patient-oriented research principles to accelerate care improvements for patients with advanced cancer of African and Latin American descent. METHODS: This is a community-based participatory research study that will take place in two Canadian provinces. Patients and community members representatives have been engaged as partners in the planning and design of the study. We have formed a patient advisory council (PAC) with patient partners to guide the development of the Access to Palliative Care Strategy for people of African and Latin American descent. We will engage100 participants consisting of advanced cancer patients, families, and community members of African and Latin American descent, and health care providers. We will conduct in-depth interviews to delineate participants' experiences of access to palliative care. We will explore the intersections of race, gender, socioeconomic status, language barriers, and other social categorizations to elucidate their role in diverse access experiences. These findings will inform the development of an action plan to increase access to palliative care that is tailored to our study population. We will then organize conversation series to examine together with community partners and healthcare providers the appropriateness, effectiveness, risks, requirements, and convenience of the strategy. At the end of the study, we will hold knowledge exchange gatherings to share findings with the community. DISCUSSION: This study will improve our understanding of how patients with advanced cancer from racialized communities in Canada access palliative care. Elements to address gaps in access to palliative care and reduce inequities in these communities will be identified. Based on the study findings a strategy to increase access to palliative care for this population will be developed. This study will inform ways to improve access to palliative care for racialized communities in other parts of Canada and globally.

Blocking Hemopexin With Specific Antibodies: A New Strategy for Treating Diabetic Retinopathy.

Hemopexin (HPX) is overexpressed in the retina of patients with diabetes and induces the breakdown of the blood-retinal barrier in vitro. The aim of this study was to evaluate whether HPX blockade by specific antibodies (aHPX) could avoid vascular leakage in vivo and microvascular angiogenesis in vitro and ex vivo. For this purpose, the effect of intravitreal (IVT) injections of aHPX on vascular leakage was evaluated in db/db mice and rats with streptozotocin-induced diabetes using the Evans Blue method. Retinal neurodegeneration and inflammation were also evaluated. The antiangiogenic effect of aHPX on human retinal endothelial cells (HRECs) was tested by scratch wound healing and tube formation using standardized methods, as well as by choroidal sprouting assays from retinal explants obtained in rats. We found that IVT injection of aHPX significantly reduced vascular leakage, retinal neurodegeneration, and inflammation. In addition, treatment with aHPX significantly reduced HREC migration and tube formation induced by high glucose concentration and suppressed choroidal sprouting even after vascular endothelial growth factor stimulation, with this effect being higher than obtained with bevacizumab. The antipermeability and antiangiogenic effects of IVT injection of aHPX suggest the blockade or inhibition of HPX as a new strategy for the treatment of advanced stages of diabetic retinopathy. ARTICLE HIGHLIGHTS: Hemopexin (HPX) is the best-characterized permeability factor in steroid-sensitive nephrotic syndrome. We have previously reported that HPX is overexpressed in the retina of patients with diabetes and induces the breakdown of the blood-retinal barrier in vitro. Here, we report that intravitreal injection of anti-HPX antibodies significantly reduces vascular leakage, retinal neurodegeneration, and inflammation in diabetic murine models and that the immunoneutralization of HPX exerts a significant antiangiogenic effect in vitro and in retinal explants. The blockade of HPX can be considered as a new therapy for advanced stages of diabetic retinopathy.

Improving access to palliative care for people experiencing socioeconomic inequities: findings from a community-based pilot research study. / Améliorer l'accès aux soins palliatifs pour les personnes confrontées à des iniquités socioéconomiques : conclusions d'une étude pilote de recherche communautaire.

INTRODUCTION: In Canada, people experiencing socioeconomic inequities have higher rates of late diagnosis and lower survival rates than the general population. Palliative care services focussed on this population are scarce. We developed a community-based nursing intervention to improve access to palliative care for people experiencing socioeconomic inequities and living with life-limiting illnesses in an urban Canadian setting. METHODS: This community-based, qualitative research study combined critical and participatory research methodologies. The study was conducted in partnership with the Palliative Care Outreach Advocacy Team (PCOAT) based in Edmonton, Alberta, a team dedicated to serving populations experiencing socioeconomic inequities who require palliative care. Following an exploratory phase that served to delineate the intervention, we undertook a one-year pilot implementation during which a part-time registered nurse (RN) joined PCOAT. The RN engaged in trust building, resolution of health and practical needs and complex care coordination. Twenty-five patients participated in the intervention. Participants were interviewed at least once to explore their experiences with the intervention. Data were analyzed through thematic analysis. RESULTS: Most participants were men, were Indigenous and had advanced cancer. Participants had significant financial concerns, lived or had lived in precarious housing situations and had previously faced serious challenges accessing health care. Participants reported social and health needs including housing, finances, transportation, symptom control, harm reduction and end-of-life care. Participants reported improved access to health and social services and expressed satisfaction with the study intervention. CONCLUSION: Study findings suggest the study intervention may have contributed to improved access to palliative care, improved experiences for participants and increased equity in the delivery of care.

Nurse-led adult palliative care models in low- and middle-income countries: A scoping review.

AIMS: To map evidence on the nature and extent of use of nurse-led palliative care models in low- and middle-income countries serving adults with life-limiting conditions. DESIGN: A scoping review of the literature was undertaken. DATA SOURCES: A systematic search was performed from database inception to March 2022 in: Medline, EMBASE, CINAHL, Wiley Cochrane Library, SCOPUS, Web of Science, SciELO and Global Health. Main search terms included: Nurse-led AND Palliative care AND Low-and middle-income countries. Grey literature was searched from Proquest Dissertations and Theses Global, the World Health Organization and selected palliative care websites. We searched the reference list of included articles for additional studies. REVIEW METHODS: We used the framework by Arksey and O'Malley and the PRISMA-ScR guidelines. Titles and abstracts were screened by one reviewer and full text by two reviewers. Thematic analysis was used to synthesize data and results are presented descriptively using themes and categories. RESULTS: Eighteen studies were included, with majority from Sub-Saharan Africa (10/20). Three nurse-led palliative care models emerged: nurse-led empowering care, nurse-led symptom control and nurse-led multicomponent palliative care. They served particularly cancer and HIV patients and were delivered in person or by telehealth care. Reported outcomes were adherence to therapy, improved self-care ability, improved quality of life and increased access to palliative. CONCLUSIONS: The use of nurse-led palliative care in low- and middle-income countries is in its developing stages and seems feasible. Nursing roles in in low- and middle-income countries need to be expanded by developing advanced practice nurses and nurse practitioner programmes, with palliative care content. More impact evaluation studies on the use of nurse-led palliative care models in these countries are needed. IMPACT: This review highlights nurse-led care models that can enhance access and quality of life of patients with life-limiting conditions in low- and middle-income countries.

An integrative review on the oncology nurse navigator role in the Canadian context.

Several Canadian provincial cancer agencies have adopted a nurse-led model of patient navigation to decrease care fragmentation in the system. The scope of competencies of the oncology nurse navigator (ONN) in Canada has evolved over the years in response to emerging cancer care challenges. This integrative review aimed to outline the scope of competencies of the ONN role in Canada. Three databases were searched since its inception to identify Canadian studies or theoretical papers on the role of ONNs. The search yielded 62 articles of which 39 were included in the review. Three interdependent role domains were identified. The first domain of care coordinator highlighted the ONN as a coordinator of health and practical needs along the care journey. The second framed the ONN as a change agent, through increasing patients' health literacy, creating partnerships, and trusting relationships. ONNs were also described as a supporter of wellbeing, or a champion of emotional, multidimensional needs, and a transformer of the context of care. All domains were central to the navigator's success in addressing inequities in care and improving patient outcomes across care settings.

Cell therapy with hiPSC-derived RPE cells and RPCs prevents visual function loss in a rat model of retinal degeneration.

Photoreceptor loss is the principal cause of blindness in retinal degenerative diseases (RDDs). Whereas some therapies exist for early stages of RDDs, no effective treatment is currently available for later stages, and once photoreceptors are lost, the only option to rescue vision is cell transplantation. With the use of the Royal College of Surgeons (RCS) rat model of retinal degeneration, we sought to determine whether combined transplantation of human-induced pluripotent stem cell (hiPSC)-derived retinal precursor cells (RPCs) and retinal pigment epithelial (RPE) cells was superior to RPE or RPC transplantation alone in preserving retinal from degeneration. hiPSC-derived RPCs and RPE cells expressing (GFP) were transplanted into the subretinal space of rats. In vivo monitoring showed that grafted cells survived 12 weeks in the subretinal space, and rats treated with RPE + RPC therapy exhibited better conservation of the outer nuclear layer (ONL) and visual response than RPE-treated or RPC-treated rats. Transplanted RPE cells integrated in the host RPE layer, whereas RPC mostly remained in the subretinal space, although a limited number of cells integrated in the ONL. In conclusion, the combined transplantation of hiPSC-derived RPE and RPCs is a potentially superior therapeutic approach to protect retina from degeneration in RDDs.

Burden of depression among Canadian adults with cancer; results from a national survey.

OBJECTIVE: To assess the prevalence and association of depression among Canadian adults with cancer in a population-based context. METHODS: The Canadian Community Health Survey (CCHS) (2015-2016) was accessed and adult participants with cancer who completed the Personal Health Questionnaire (PHQ9) were included in the current analysis. Multivariable logistic regression was conducted to elucidate the factors associated with the development of depression. An additional multivariable logistic regression analysis was conducted to evaluate the association of depression with ever contemplating suicide (suicidal ideation). RESULTS: A total of 867 participants with cancer have completed PHQ9 were included in the current analysis (including 603 participants (69.6%) without depression (PHQ9 ≤ 4) and 264 participants (30.4%) with depression (PHQ9 > 4)). Moreover, 92 participants (10.6%) fulfill the criteria for moderate/severe depression (PHQ9 > 9). The following factors were associated with the presence of depression (PHQ9 > 4), female sex (OR for males versus females: 0.56; 95% CI: 0.34-0.93; P = 0.02); poor self-perceived health (OR for excellent health versus poor health: 0.12; 95% CI: 0.02-0.62; P = 0.01) and poor self-perceived mental health (OR for excellent mental health versus poor mental health: 0.02; 95% CI: <0.01-0.24; P < 0.01). Additional multivariable logistic regression analysis showed that depression (PHQ9 > 4) was associated with a higher probability of suicidal ideation (OR for no depression versus depression: 0.43; 95% CI: 0.21-0.91; P = 0.02). CONCLUSIONS: Depression seems to be an underdiagnosed and possibly undertreated comorbid condition among Canadian adults with cancer.

Transcriptomics analysis of Ccl2/Cx3cr1/Crb1rd8 deficient mice provides new insights into the pathophysiology of progressive retinal degeneration.

Chronic oxidative stress and immune dysregulation are key mechanisms involved in the pathogenesis of most retinal degenerative diseases, including age-related macular degeneration. The Ccl2-/-/Cx3cr1-/-/Crb1rd8/rd8 mouse model develops a progressive degeneration phenotype, with photoreceptor atrophy, drusen-like lesions or pigment alterations at an early age; however, the role of oxidative stress and immune function in the pathogenesis of the model is poorly understood. We performed a comprehensive characterization of the Ccl2-/-/Cx3cr1-/-/Crb1rd8/rd8 mouse to evaluate how these pathways influence pathogenesis. We generated a Ccl2-/-/Cx3cr1-/- double-knockout (DKO) mouse on a C57BL/6N background (with the rd8 mutation of the Crb1 gene), assessed its retina status and function during 9 months in both in vivo and post-mortem analysis, and performed a comprehensive transcriptomic analysis. DKOrd8 mice presented focal retinal lesions with increased infiltration of microglia and involvement of Müller cells. Lesions progressed to thinning of the photoreceptor nuclear layer, causing a loss in retinal function. Transcriptomics analysis revealed major differential expression of genes involved in oxidative stress and neuronal function, in particular genes related to the mitochondrial electron transport chain and antioxidant cellular response. Our results suggest that alterations in chemokine signaling combined with the rd8 mutation in Ccl2-/-/Cx3cr1-/-/Crb1rd8/rd8 mice involve early changes in several pathways associated with age-related macular degeneration, highlighting the relevance of these processes in the pathological retinal degeneration in the DKOrd8 model.

Desafios da enfermagem na promoção de práticas de equidade em saúde: um diálogo entre a enfermagem no Brasil e no Canadá / Nursing challenges to enact health equity in practice: a Brazilian-Canadian nursing dialogue / Retos de enfermería en la promoción de prácticas de equidad en salud: diálogo entre enfermería de Brasil y Canadá

No presente artigo desenvolvemos um diálogo reflexivo acerca da equidade na saúde, traçando um paralelo entre os desafios próprios da prática de Enfermagem com equidade no Brasil e no Canadá. O conceito de equidade em saúde implica o reconhecimento das injustiças sofridas por alguns grupos populacionais, considerando-se que a distribuição de bens e serviços aos indivíduos abarca o reconhecimento de suas diferenças e necessidades distintas. O princípio da equidade em saúde se estabelece no âmbito das próprias condições de saúde e do acesso e utilização dos serviços com base em um parâmetro de distribuição heterogênea desses serviços. Os principais responsáveis pelas diferenças nas condições de saúde de distintos grupos populacionais são fatores sociais que podem ser alterados ou controlados por políticas públicas, ou seja, as iniquidades em saúde devem ser compreendidas como as diferenças desnecessárias e evitáveis. No que se refere às práticas de Enfermagem, em uma perspectiva sociológica, elas devem ser entendidas como práticas sociais que devem possibilitar a autonomia e o exercício da cidadania das pessoas, cabendo questionar sé é possível atuar como profissionais de saúde na perspectiva da equidade. Nesse contexto, entendemos que a proposição de práticas de equidade em saúde, na perspectiva da Enfermagem, pressupõe a superação de complexos desafios que podem ser analisados a partir de cinco dimensões: assistência, gestão, formação/educação permanente, engajamento político e pesquisa.(AU)

In this paper we develop a reflective dialogue about health equity, drawing a parallel between selected challenges to enact equity in nursing practice in Brazil and Canada. The concept of health equity implies the recognition of injustices suffered by some population groups, considering that a distribution of goods and services to individuals requires recognition of their differences and distinct needs. The principle of health equity emerges in light of inequalities in health and access to health care services. Living and social conditions are critical factors in the development of health inequities that affect population groups. These factors are modifiable and controllable by public policies. Health inequities are considered unnecessary, unjust, and avoidable differences in the health status of populations. Nursing practices can be understood as social practices that seek to enable people to enact their autonomy and citizenship. A proposal for health equity practices, from the perspective of nursing, requires that we tackle complex challenges that can be analyzed from the perspective of five domains: clinical practice, nursing education, research, administration and political engagement.(AU)

En este artículo llevamos a cabo un diálogo reflexivo sobre la equidad en salud, trazando un paralelo entre los retos propios de la práctica de enfermería con equidad en Brasil y Canadá. El concepto de equidad en salud implica el reconocimiento de las injusticias sufridas por algunos grupos de población, considerando que la distribución de bienes y servicios a individuos incluye el reconocimiento de sus diferencias y necesidades distintas. El principio de equidad en salud se establece dentro del alcance de las condiciones de salud y del acceso y uso de los servicios en función de un parámetro de distribución heterogénea de estos servicios. Los principales responsables de las diferencias en las condiciones de salud de los diferentes grupos de población son los factores sociales que pueden ser alterados o controlados por las políticas públicas, es decir, las inequidades en salud deben entenderse como diferencias innecesarias y evitables. Con respecto a las prácticas de enfermería, desde una perspectiva sociológica, deben entenderse como prácticas sociales que deberían permitir la autonomía de las personas y el ejercicio de la ciudadanía, y vale la pena preguntarse si es posible actuar como profesionales de la salud desde la perspectiva de la equidad. En este contexto, entendemos que la propuesta de prácticas de equidad en salud, desde la perspectiva de la enfermería, presupone superar retos complejos que se pueden analizar desde cinco dimensiones: asistencia, gestión, capacitación / educación permanente, compromiso político e investigación.

Social disparities and symptom burden in populations with advanced cancer: specialist palliative care providers' perspectives.

Disparities in access to palliative care services for populations with social disparities have been reported in Western countries. Studies indicate that these populations tend to report higher symptom distress than other population groups. We need to further investigate how social disparities influence symptom burden to improve symptom relief in these populations. PURPOSE: To examine the perspectives of specialist palliative care providers concerning the relationship between social disparities and symptom burden in populations with advanced cancer. METHODS: Two sequential qualitative studies that followed a combination of interpretive and critical methodologies. The interpretive approach was outlined by van Manen's hermeneutic phenomenology while the critical component was informed by the works of Paulo Freire. Participants involved two specialist palliative care teams from a large acute care hospital and a large cancer center in Western Canada. Participants included 11 palliative care providers including registered nurses, nurse practitioners, physicians, and pharmacists. RESULTS: Participants perceived that social conditions that might aggravate symptom burden included low income, low education, lack of social support, language barriers, and rurality. The relationship between income and symptom burden reflected diverse views. Participants identified populations prone to complex symptom burden including homeless individuals, Indigenous people, people with a history of addictions, and people with mental health or psychosocial issues. CONCLUSION: Participants perceived that social disparities may increase symptom complexity in populations with advanced cancer. Participants did not identify ethnicity and gender as influencing symptom burden. Further research is needed to examine the interactions of social disparities, patient individuality, and symptom burden.

Quality of Life among Female Cancer Survivors in Africa: An Integrative Literature Review.

Quality of life (QOL) has been studied extensively among cancer populations in high income countries where cancer care resources are available to many. Little is known concerning the QOL of cancer groups residing in Africa where resources can be scarce. The integrative review of the literature explored and critically examined studies that had addressed QOL in female cancer survivors in Africa. The extent to which QOL studies incorporated a cultural perspective was also examined. Research studies published between 2005 and 2015 were retrieved from five databases: CINAHL, MEDLINE, SCOPUS, ProQuest dissertations and Theses full text, and GlobalHealth. Primary qualitative or quantitative studies regardless of sample size or setting were included. A total of 300 studies were identified and 28 full text studies were retrieved and assessed for eligibility. Eight studies met inclusion criteria. Factors that affected the QOL were socio-demographic especially age, education, employment, income and residence; illness-related factors such as having advanced cancer and multiple symptoms; treatment-related factors associated with surgery and radiotherapy; psychosocial factors such as support and anxiety; and cultural factors including fatalism and bewitching. Practice implications entail increasing awareness among nurses and allied healthcare providers of the potential effects on QOL of a cancer diagnosis and treatment of female cancers such as pain, fatigue, sexual dysfunction, hormonal and body image changes, anxiety, depression and cultural practices. Failure to identify and deal with these may result in poor treatment adherence, low self-esteem, and ultimately poor QOL.

Developing Navigation Competencies to Care for Older Rural Adults with Advanced Illness.

Navigators help rural older adults with advanced illness and their families connect to needed resources, information, and people to improve their quality of life. This article describes the process used to engage experts - in rural aging, rural palliative care, and navigation - as well as rural community stakeholders to develop a conceptual definition of navigation and delineate navigation competencies for the care of this population. A discussion paper on the important considerations for navigation in this population was developed followed by a four-phased Delphi process with 30 expert panel members. Study results culminated in five general navigation competencies for health care providers caring for older rural persons and their families at end of life: provide patient/family screening; advocate for the patient/family; facilitate community connections; coordinate access to services and resources; and promote active engagement. Specific competencies were also developed. These competencies provide the foundation for research and curriculum development in navigation.

Comparative study of human embryonic stem cells (hESC) and human induced pluripotent stem cells (hiPSC) as a treatment for retinal dystrophies.

Retinal dystrophies (RD) are major causes of familial blindness and are characterized by progressive dysfunction of photoreceptor and/or retinal pigment epithelium (RPE) cells. In this study, we aimed to evaluate and compare the therapeutic effects of two pluripotent stem cell (PSC)-based therapies. We differentiated RPE from human embryonic stem cells (hESCs) or human-induced pluripotent stem cells (hiPSCs) and transplanted them into the subretinal space of the Royal College of Surgeons (RCS) rat. Once differentiated, cells from either source of PSC resembled mature RPE in their morphology and gene expression profile. Following transplantation, both hESC- and hiPSC-derived cells maintained the expression of specific RPE markers, lost their proliferative capacity, established tight junctions, and were able to perform phagocytosis of photoreceptor outer segments. Remarkably, grafted areas showed increased numbers of photoreceptor nuclei and outer segment disk membranes. Regardless of the cell source, human transplants protected retina from cell apoptosis, glial stress and accumulation of autofluorescence, and responded better to light stimuli. Altogether, our results show that hESC- and hiPSC-derived cells survived, migrated, integrated, and functioned as RPE in the RCS rat retina, providing preclinical evidence that either PSC source could be of potential benefit for treating RD.

Non-pharmacological cancer pain interventions in populations with social disparities: a systematic review and meta-analysis.

INTRODUCTION: Global advances in pain relief have improved the quality of life of cancer populations. Yet, variation in cancer pain outcomes has been found in populations with social disparities compared to mainstream groups. Populations with social disparities bear an inequitable distribution of resources such as ethnic minorities, low income individuals, and women in vulnerable circumstances. RESEARCH PURPOSE: A systematic review and meta-analysis of the effect of non-pharmacological cancer pain interventions in cancer populations with social disparities of income, ethnicity, or gender. METHODS: Randomized controlled trials, controlled trials, and before and after studies were targeted through comprehensive multidatabase searches. Two reviewers independently screened titles/abstracts for potentially relevant studies and reviewed the full text of relevant articles for inclusion. Data were extracted from included studies by one reviewer and verified by another reviewer. Four reviewers independently completed quality assessment. Studies were grouped by intervention. Effects were evaluated for heterogeneity and pooled. RESULTS: The search found 5219 potential records. Full text of 26 reports was evaluated. Three randomized controlled trials (RCTs) met inclusion criteria, targeting ethnic minorities and underserved populations and/or women. Interventions included education, coaching, and online support groups. Studies found no significant differences in pain reduction between intervention and control groups or between ethnic minorities and their counterparts. A high risk of bias was found in all studies. Meta-analysis found no statistically significant difference on pain intensity among underserved groups, ethnic minorities, or between ethnic minorities and white counterparts. CONCLUSION: Results show the need to examine supportive care interventions particularly in populations with social disparities.

Do nutritional supplements have a role in age macular degeneration prevention?

Purpose. To review the proposed pathogenic mechanisms of age macular degeneration (AMD), as well as the role of antioxidants (AOX) and omega-3 fatty acids ( ω -3) supplements in AMD prevention. Materials and Methods. Current knowledge on the cellular/molecular mechanisms of AMD and the epidemiologic/experimental studies on the effects of AOX and ω -3 were addressed all together with the scientific evidence and the personal opinion of professionals involved in the Retina Group of the OFTARED (Spain). Results. High dietary intakes of ω -3 and macular pigments lutein/zeaxanthin are associated with lower risk of prevalence and incidence in AMD. The Age-Related Eye Disease study (AREDS) showed a beneficial effect of high doses of vitamins C, E, beta-carotene, and zinc/copper in reducing the rate of progression to advanced AMD in patients with intermediate AMD or with one-sided late AMD. The AREDS-2 study has shown that lutein and zeaxanthin may substitute beta-carotene because of its potential relationship with increased lung cancer incidence. Conclusion. Research has proved that elder people with poor diets, especially with low AOX and ω -3 micronutrients intake and subsequently having low plasmatic levels, are more prone to developing AMD. Micronutrient supplementation enhances antioxidant defense and healthy eyes and might prevent/retard/modify AMD.
