Racial Disparities in End-Stage Kidney Disease Outcomes among Asians and Native Hawaiians and Other Pacific Islanders across Geographic Residence.

INTRODUCTION: While Asian and Native Hawaiian and other Pacific Islander (NHOPI) patients have a high prevalence of kidney disease risk factors, there are sparse data examining their end-stage kidney disease (ESKD) outcomes. As Hawaii has high representation of Asian and NHOPI individuals, we compared their ESKD outcomes based on residence in the mainland USA versus Hawaii/Pacific Islands (PIs). MATERIALS AND METHODS: Using United States Renal Data System data, we examined the impact of geographic residence in the mainland versus Hawaii/PIs on race-mortality associations among incident ESKD patients transitioning to dialysis over January 1, 2000-December 31, 2016 using Cox regression. We examined likelihood of post-dialysis kidney transplantation using Cox models and cumulative incidence curves. RESULTS: Compared with White patients in the mainland, Asian and NHOPI patients in the mainland had lower mortality: adjusted HRs (95% CIs) 0.67 (0.66-0.67) and 0.72 (0.70-0.73), respectively. When examining Asian and NHOPI patients in Hawaii/PIs, survival benefit was attenuated in Asian and diminished to the null in NHOPI patients (ref: mainland White patients). Cumulative incidence curves comparing Asian, NHOPI, and White patients showed Asian and NHOPI patients in the mainland had the highest likelihood of transplantation, whereas NHOPI and Asian patients in Hawaii/PIs had the lowest likelihood. CONCLUSION: In the mainland, Asian and NHOPI patients had lower mortality versus White patients, whereas in Hawaii/PIs, this survival benefit was diminished in Asian and mitigated in NHOPI patients. NHOPI and Asian patients in Hawaii/PIs had less transplantation versus those in the mainland. Further research is needed to uncover factors contributing to differential ESKD outcomes among Asian and NHOPI patients across geographic residence.

Racial and Ethnic Differences in Chronic Kidney Disease and Its Risk Factors among Asian-Americans and Pacific Islanders in Hawaii.

BACKGROUND: Several studies suggest that Asian-American and Native Hawaiian and Other Pacific Islander (NHOPI) racial/ethnic groups have a heightened risk of chronic kidney disease (CKD), but provide limited inference due to the aggregation of these groups into a single racial/ethnic category. We thus examined the association of granularly defined racial/ethnic groups with specific CKD indicators among a diverse group of participants from the National Kidney Foundation of Hawaii's Kidney Early Detection Screening (KEDS) Program. METHODS: Among 1,243 participants enrolled in 19 KEDS screening events over 2006-2009, we examined the association between Asian-American and NHOPI groups and specific CKD indicators, defined as self-reported CKD, microalbuminuria, and macroalbuminuria, using multivariable logistic regression. We then examined associations of race/ethnicity with various CKD risk factors. RESULTS: The most predominant racial/ethnic groups were White (22.0%), Multiracial (18.9%), Japanese (19.2%), Filipino (13.4%), NHOPI (8.4%), and Chinese (4.5%) participants. NHOPI and Chinese participants had a higher risk of microalbuminuria (adjusted ORs [aORs] [95% CIs] 2.48 [1.25-4.91] and 2.37 [1.07-5.27], respectively), while point estimates for all other minority groups suggested higher risk (reference: Whites). NHOPI participants also had a higher risk of macroalbuminuria and self-reported CKD. While most minorities had a higher risk of diabetes and hypertension, NHOPI and Multiracial participants had a higher risk of obesity, whereas the East Asian groups had a lower risk. CONCLUSIONS: In this community-based cohort, compared with Whites, Asian-Americans had a higher risk of early CKD indicators, whereas NHOPIs had a higher risk of more severe CKD indicators. Further studies are needed to elucidate the distinct pathways leading to CKD across diverse racial/ethnic groups in Hawaii.

Living Well With Kidney Disease and Effective Symptom Management: Consensus Conference Proceedings.

Chronic kidney disease (CKD) confers a high burden of uremic symptoms that may be underrecognized, underdiagnosed, and undertreated. Unpleasant symptoms, such as CKD-associated pruritus and emotional/psychological distress, often occur within symptom clusters, and treating 1 symptom may potentially alleviate other symptoms in that cluster. The Living Well with Kidney Disease and Effective Symptom Management Consensus Conference convened health experts and leaders of kidney advocacy groups and kidney networks worldwide to discuss the effects of unpleasant symptoms related to CKD on the health and well-being of those affected, and to consider strategies for optimal symptom management. Optimizing symptom management is a cornerstone of conservative and preservative management which aim to prevent or delay dialysis initiation. In persons with kidney dysfunction requiring dialysis (KDRD), incremental transition to dialysis and home dialysis modalities offer personalized approaches. KDRD is proposed as the preferred term given the negative connotations of "failure" as a kidney descriptor, and the success stories in CKD journeys. Engaging persons with CKD to identify and prioritize their personal values and individual needs must be central to ensure their active participation in CKD management, including KDRD. Person-centered communication and care are required to ensure diversity, equity, and inclusion; education/awareness that considers the health literacy of persons with CKD; and shared decision-making among the person with CKD, care partners, and providers. By putting the needs of people with CKD, including effective symptom management, at the center of their treatment, CKD can be optimally treated in a way that aligns with their goals.

Community perceptions of transactional sex with children and adolescent girls, a qualitative study in favelas of Rio de Janeiro.

The sexual exploitation of children and adolescents is a frequently underestimated health problem which includes transactional sex (TS), or the practice of sexual activity based on an expected return of benefits, favours and/or support in some form. This qualitative study focuses on age-disparate transactional sex (ATS) in urban favela communities of Rio de Janeiro between adult men (over 18) and girls and adolescents (G/A) (under 18), involving a minimum 5-year age disparity. We have employed social norms theory as a framework to identify the prevailing social norms contributing to or protecting children and adolescents from these relationships. Data collection utilised semi-structured interviews (n = 30) and ten focus groups with a total of 130 men/boys and women/girls selected through purposive sampling and varying in age from 15 to 65. Overall the findings identify factors, especially the essentialisation of gender, which promote the acceptability of ATS. When ATS surpassed the acceptability threshold, social norms discouraged direct interference. Concluding remarks point to possible strategies for reducing the occurrence of ATS. These must include girls, boys, women and men with community involvement in the deconstruction of social norms involving gender, age and economic consumption.

Asian Americans & chronic kidney disease in a nationally representative cohort.

BACKGROUND: There is a paucity of specific data on early stages of chronic kidney disease (CKD) among Asian Americans (AAs). The objective of this study was to examine the independent association of Asian race/ethnicity and socio-demographic and co-morbidity factors with markers of early kidney damage, ascertained by ACR levels, as well as kidney dysfunction, ascertained by eGFR levels in a large cross-sectional sample of AAs enrolled in the National Health and Nutrition Examination Survey (NHANES). METHODS: Secondary data analyses of the NHANES 2011-2014 data of a nationally representative sample of 5907 participants 18 years and older, US citizens, and of Asian and White race. NHANES data included race (Asian vs. White), as well as other socio-demographic information and comorbidities. Urine albumin-to-creatinine ratio (ACR) categories and estimated glomerular filtration rate (eGFR) were used as indicators for CKD. Descriptive analyses using frequencies, means (standard deviations), and chi-square tests was first conducted, then multivariable logistic regression serial adjustment models were used to examine the associations between race/ethnicity, other socio-demographic factors (age, sex, education), and co-morbidities (obesity, diabetes, hypertension) with elevated ACR levels (A2 & A3 - CKD Stages 3 and 4-5, respectively) as well as reduced eGFR (G3a-G5 and G3b -G5 - CKD Stage 3-5). RESULTS: AAs were more likely than White participants to have ACR levels > 300 mg/g (A3) (adjusted OR (aOR) (95% CI) 2.77 (1.55, 4.97), p = 0.001). In contrast, adjusted analyses demonstrated that AAs were less likely to have eGFR levels < 60 ml/min/1.73 m2 (G3a-G5) (aOR (95% CI) 0.50 (0.35, 0.72), p < .001). CONCLUSIONS: This is one of the first large U.S. population-based studies of AAs that has shown a comparatively higher risk of elevated ACR > 300 mg/g levels (A3) but lower risk of having eGFR levels < 60 ml/min/1.732 m2 (G3a-G5). The findings support the need to address the gaps in knowledge regarding disparities in risk of early stage CKD among AAs.

Insights from Screening a Racially and Ethnically Diverse Population for Chronic Kidney Disease.

BACKGROUND: The value of chronic kidney disease (CKD) screening in the general population remains unclear but may be beneficial in populations with high disease prevalence. We examined risk factors for albuminuria among participants in a state-wide CKD screening program in Hawaii. METHODS: The National Kidney Foundation of Hawaii Kidney Early Detection Screening (NKFH-KEDS) program held 19 CKD screening events from 2006 to 2012. Participants rotated through 5 stations during which sociodemographic, blood glucose, urine albumin-to-creatinine ratio (ACR), and spot urine albumin data were collected. Multivariate logistic regression analyses (adjusted for age, sex, race/ethnicity, body mass index [BMI]) were used to identify clinical predictors of abnormal ACR (≥30 µg/mg) and abnormal spot urine albumin (>20 mg/L) levels. RESULTS: Among 1,190 NKFH-KEDS participants who met eligibility criteria, 13 and 49% had abnormal ACR and urine albumin levels, respectively. In multivariate logistic regression analyses, participants of older age (>65 years), Asian and Pacific Islander race/ethnicity, BMI ≥30 kg/m2, and with hypertension had higher risk of abnormal ACR. Being of older age; Asian, Pacific Islander, and Mixed race/ethnicity; and having diabetes was associated with higher risk of abnormal urine albumin levels in adjusted analyses. CONCLUSIONS: NKFH-KEDS participants of older age; Asian and Pacific Islander race/ethnicity; and with obesity, hypertension, and diabetes had higher risk of kidney damage defined by elevated ACR and urine albumin levels. Further studies are needed to determine whether targeted screening programs can result in timely identification of CKD and implementation of interventions that reduce cardiovascular disease, death, and progression to end-stage renal disease.

Evaluation of the National Kidney Foundation of Hawai'i's Kidney Early Detection Screening program.

PURPOSE: Discussion of the formative program evaluation results of the National Kidney Foundation of Hawai'i (NKFH) Kidney Early Detection Screening (KEDS) program for Chronic Kidney Disease (CKD). The formative program evaluation had 921 participants who enrolled in the NKFH KEDS screening program between 2006-2009. The evaluation included 14 KEDS sites in Honolulu, Maui, and Hawai'i counties. MAIN FINDINGS: Based on the results of the formative evaluation, process changes were made to program recruitment, training, and procedure. A majority of participants were women, between 46 and 75 years old. The ethnic groups represented were: White, Japanese, Hawaiian/Part Hawaiian, Filipino, Chinese, Hispanic, and Other. The three most common risk factors identified were: (1) blood relative with diabetes, (2) blood relative with cardiovascular disease, and (3) self-reported high blood pressure. Participants in Hawai'i County had the highest mean for total risk factors. Ethnicity, gender, and age were significantly associated with selected vital signs, physiological measures, and lab tests. Fourteen percent of KEDS participants had an abnormal albumin:creatinine (A:C) ratio and 12% had an abnormal glomerular filtration rate (GFR), requiring follow-up by a health care professional. PRINCIPAL CONCLUSIONS: The KEDS formative program evaluation findings improved program planning and implementation. Summative program evaluation and implications for conducting research studies in this area will be the next step in the evaluation process.

Advance care planning among Asian Americans and Native Hawaiians receiving haemodialysis.

AIM: To explore the attitudes about death and dying, advance care planning (ACP), and completion of ACP among Asian Americans (AAs) and Native Hawaiians (NHs) receiving haemodialysis. This study was a descriptive, cross-sectional survey design. METHOD: A convenience sample of 50 participants aged 30-82 years was recruited from four outpatient dialysis centers in Honolulu, Hawaii and interviewed face-to-face using a 43-item end-of-life community survey. A majority of participants perceived dying as an important part of life and were comfortable talking about death, but expressed concerns and fears about end-of-life issues. Aspects of ACP, such as planning a funeral service, getting finances in order, and completing the will were important. While most participants' attitudes about ACP were positive, less than half (40%) had completed ACP. Most participants preferred initiating end-of-life conversations with family. CONCLUSIONS: The main conclusions drawn from this study are that there is a need for ACP and secondly that AAs and NHs would prefer to discuss ACP with family members rather than health or legal professionals. Findings from this preliminary study build on the need to use a theoretical framework in which to develop sound instruments and effective interventions to promote ACP completion among AAs and NHs receiving haemodialysis.

Dinosaur diversity and the rock record.

Palaeobiodiversity analysis underpins macroevolutionary investigations, allowing identification of mass extinctions and adaptive radiations. However, recent large-scale studies on marine invertebrates indicate that geological factors play a central role in moulding the shape of diversity curves and imply that many features of such curves represent sampling artefacts, rather than genuine evolutionary events. In order to test whether similar biases affect diversity estimates for terrestrial taxa, we compiled genus-richness estimates for three Mesozoic dinosaur clades (Ornithischia, Sauropodomorpha and Theropoda). Linear models of expected genus richness were constructed for each clade, using the number of dinosaur-bearing formations available through time as a proxy for the amount of fossiliferous rock outcrop. Modelled diversity estimates were then compared with observed patterns. Strong statistically robust correlations demonstrate that almost all aspects of ornithischian and theropod diversity curves can be explained by geological megabiases, whereas the sauropodomorph record diverges from modelled predictions and may be a stronger contender for identifying evolutionary signals. In contrast to other recent studies, we identify a marked decline in dinosaur genus richness during the closing stages of the Cretaceous Period, indicating that the clade decreased in diversity for several million years prior to the final extinction of non-avian dinosaurs at the Cretaceous-Palaeocene boundary.

Fortification of selected foodstuffs with folic acid in the UK: consumer research carried out to inform policy recommendations.

BACKGROUND: The UK Food Standards Agency Board identified four options to increase folate intake in women of reproductive age in order to reduce the risk of neural tube defect (NTD) affected pregnancies; these ranged from continuing with current policy, to mandatory fortification of bread or flour with folic acid. In order to appraise these options, the agency carried out a consultation, and also commissioned four pieces of research. This paper provides detailed information about two of the research studies, which used qualitative research approaches to gather consumer evidence. METHODS: Study 1: This was carried out with people from a wide range of demographic backgrounds. A 'reconvened group' methodology was used, with five groups convened twice, in five geographical locations. In addition paired, in depth face-to-face interviews were conducted with female black and ethnic minority consumers. Study 2: This was carried out with young mothers living in deprived communities. The approach used for this study was in depth face-to-face interviews (n = 24). In addition, discussions were held in seven friendship groups. RESULTS: Study 1: only a minority of participants knew about a link between spina bifida and folic acid, and these tended to be women with young families. After the provision of some information about the causes and impacts of NTDs, the majority were in favour of action to tackle the issue. Support for mandatory fortification increased considerably during the study, and at the final discussion, this option was most preferred. Study 2: In this group, there was a fatalistic approach to pregnancy and to health. The women were less likely to change established habits if this required effort, money or doing something unfamiliar. They tended to actively avoid thinking about risks, by rationalizing them. Mandatory fortification was preferred by the majority of respondents. CONCLUSIONS: In this research, mandatory fortification was the preferred option. There were outstanding concerns about risk, and the maintenance of consumer choice, which would need to be addressed in policy recommendations.
