Implementing the interRAI Check-Up Comprehensive Assessment: Facilitating Care Planning and Care Coordination during the Pandemic.

Background: Long-stay home care patients are a large population of older adults with multi-morbidity and frailty. The COVID-19 pandemic posed challenges to executing care coordination and completing in-home assessments due to provincial mandates restricting in-person care. We evaluated the implementation of the interRAI Check-Up Self-Report instrument administered by phone and video. Methods: We report on a mixed-methods study, which involved the collection and analysis of survey and focus group data. Care coordinators from two regions in Ontario who had implemented the Check-Up at least once between March 2020 to September 2021 were recruited via convenience sampling. Results: A total of 48 survey respondents and 7 focus group participants consented to the study. Advantages of completing the Check-Up over the telephone or video call included: reduced travel time, reduced risk of disease transmission, familiarity with the assessment questions, and reduced time spent administering the assessment. Limitations most frequently reported were: the inability to see the living environment, hearing impairments, inability to observe non-verbal responses or cues, language barriers, difficulty building rapport, and difficulty understanding the patient. Conclusions: The Check-Up was advantageous in providing sufficient information to create a care plan when administered over the phone and by video. Implementation of the Check-Up assessment was facilitated by familiarity and alignment with other interRAI assessments. Our results indicate that population characteristics need to be taken into consideration for administration of self-report style of assessments.

Fractures and Subsequent Graft Loss and Mortality among Older Kidney Transplant Recipients.

OBJECTIVES: Older adults who undergo kidney transplantation (KT) are living longer with a functioning graft and are at risk for age-related adverse events including fractures. Understanding recipient, transplant, and donor factors and the outcomes associated with fractures may help identify older KT recipients at increased risk. We determined incidence of hip, vertebral, and extremity fractures; assessed factors associated with incident fractures; and estimated associations between fractures and subsequent death-censored graft loss (DCGL) and mortality. DESIGN: This was a prospective cohort study of patients who underwent their first KT between January 1, 1999, and December 31, 2014. SETTING: We linked data from the Scientific Registry of Transplant Recipients to Medicare claims through the US Renal Data System. PARTICIPANTS: The analytic population included 47 815 KT recipients aged 55 years or older. MEASUREMENTS: We assessed the cumulative incidence of and factors associated with post-KT fractures (hip, vertebral, or extremity) using competing risks models. We estimated risk of DCGL and mortality after fracture using adjusted Cox proportional hazards models. RESULTS: The 5-year incidence of post-KT hip, vertebral, and extremity fracture for those aged 65 to 69 years was 2.2%, 1.0%, and 1.7%, respectively. Increasing age was associated with higher hip (adjusted hazard ratio [aHR] = 1.37 per 5-y increase; 95% confidence interval [CI] = 1.30-1.45) and vertebral (aHR = 1.31; 95% CI = 1.20-1.42) but not extremity (aHR = .97; 95% CI = .91-1.04) fracture risk. DCGL risk was higher after hip (aHR = 1.34; 95% CI = 1.12-1.60) and extremity (aHR = 1.30; 95% CI = 1.08-1.57) fracture. Mortality risk was higher after hip (aHR = 2.31; 95% CI = 2.11-2.52), vertebral (aHR = 2.80; 95% CI = 2.44-3.21), and extremity (aHR = 1.85; 95% CI = 1.64-2.10) fracture. CONCLUSION: Our findings suggest that older KT recipients are at higher risk for hip and vertebral fracture but not extremity fracture; and those with hip, vertebral, or extremity fracture are more likely to experience subsequent graft loss or mortality. These findings underscore that different fracture types may have different underlying etiologies and risks, and they should be approached accordingly. J Am Geriatr Soc 67:1680-1688, 2019.

Frailty and Cognitive Function in Incident Hemodialysis Patients.

BACKGROUND AND OBJECTIVES: Patients of all ages undergoing hemodialysis (HD) have a high prevalence of cognitive impairment and worse cognitive function than healthy controls, and those with dementia are at high risk of death. Frailty has been associated with poor cognitive function in older adults without kidney disease. We hypothesized that frailty might also be associated with poor cognitive function in adults of all ages undergoing HD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: At HD initiation, 324 adults enrolled (November 2008 to July 2012) in a longitudinal cohort study (Predictors of Arrhythmic and Cardiovascular Risk in ESRD) were classified into three groups (frail, intermediately frail, and nonfrail) based on the Fried frailty phenotype. Global cognitive function (3MS) and speed/attention (Trail Making Tests A and B [TMTA and TMTB, respectively]) were assessed at cohort entry and 1-year follow-up. Associations between frailty and cognitive function (at cohort entry and 1-year follow-up) were evaluated in adjusted (for sex, age, race, body mass index, education, depression and comorbidity at baseline) linear (3MS, TMTA) and Tobit (TMTB) regression models. RESULTS: At cohort entry, the mean age was 54.8 years (SD 13.3), 56.5% were men, and 72.8% were black. The prevalence of frailty and intermediate frailty were 34.0% and 37.7%, respectively. The mean 3MS was 89.8 (SD 7.6), TMTA was 55.4 (SD 29), and TMTB was 161 (SD 83). Frailty was independently associated with lower cognitive function at cohort entry for all three measures (3MS: -2.4 points; 95% confidence interval [95% CI], -4.2 to -0.5; P=0.01; TMTA: 12.1 seconds; 95% CI, 4.7 to 19.4; P<0.001; and TMTB: 33.2 seconds; 95% CI, 9.9 to 56.4; P=0.01; all tests for trend, P<0.001) and with worse 3MS at 1-year follow-up (-2.8 points; 95% CI, -5.4 to -0.2; P=0.03). CONCLUSIONS: In adult incident HD patients, frailty is associated with worse cognitive function, particularly global cognitive function (3MS).

Changes in Frailty After Kidney Transplantation.

OBJECTIVES: To understand the natural history of frailty after an aggressive surgical intervention, kidney transplantation (KT). DESIGN: Prospective cohort study (December 2008-March 2014). SETTING: Baltimore, Maryland. PARTICIPANTS: Kidney transplantation recipients (N = 349). MEASUREMENTS: The Fried frailty score was measured at the time of KT and during routine clinical follow-up. Using a Cox proportional hazards model, factors associated with improvements in frailty score after KT were identified. Using a longitudinal analysis, predictors of frailty score changes after KT were identified using a multilevel mixed-effects Poisson model. RESULTS: At KT, 19.8% of recipients were frail; 1 month after KT, 33.3% were frail; at 2 months, 27.7% were frail; and at 3 months, 17.2% were frail. On average, frailty scores had worsened by 1 month (mean change 0.4, P < .001), returned to baseline by 2 months (mean change 0.2, P = .07), and improved by 3 months (mean change -0.3, P = .04) after KT. The only recipient or transplant factor associated with improvement in frailty score after KT was pre-KT frailty (hazard ratio = 2.55, 95% confidence interval (CI) = 1.71-3.82, P < .001). Pre-KT frailty status (relative risk (RR) = 1.49, 95% CI = 1.29-1.72, P < .001), recipient diabetes mellitus (RR = 1.26, 95% CI = 1.08-1.46, P = .003), and delayed graft function (RR = 1.22, 95% CI = 1.04-1.43, P = .02) were independently associated with long-term changes in frailty score. CONCLUSION: After KT, in adult recipients of all ages, frailty initially worsens but then improves by 3 months. Although KT recipients who were frail at KT had higher frailty scores over the long term, they were most likely to show improvements in their physiological reserve after KT, supporting the transplantation in these individuals and suggesting that pretransplant frailty is not an irreversible state of low physiological reserve.

Perceived frailty and measured frailty among adults undergoing hemodialysis: a cross-sectional analysis.

BACKGROUND: Frailty, a validated measure of physiologic reserve, predicts adverse health outcomes among adults with end-stage renal disease. Frailty typically is not measured clinically; instead, a surrogate-perceived frailty-is used to inform clinical decision-making. Because correlations between perceived and measured frailty remain unknown, the aim of this study was to assess their relationship. METHODS: 146 adults undergoing hemodialysis were recruited from a single dialysis center in Baltimore, Maryland. Patient characteristics associated with perceived (reported by nephrologists, nurse practitioners (NPs), or patients) or measured frailty (using the Fried criteria) were identified using ordered logistic regression. The relationship between perceived and measured frailty was assessed using percent agreement, kappa statistic, Pearson's correlation coefficient, and prevalence of misclassification of frailty. Patient characteristics associated with misclassification were determined using Fisher's exact tests, t-tests, or median tests. RESULTS: Older age (adjusted OR [aOR] = 1.36, 95%CI:1.11-1.68, P = 0.003 per 5-years older) and comorbidity (aOR = 1.49, 95%CI:1.27-1.75, P < 0.001 per additional comorbidity) were associated with greater likelihood of nephrologist-perceived frailty. Being non-African American was associated with greater likelihood of NP- (aOR = 5.51, 95%CI:3.21-9.48, P = 0.003) and patient- (aOR = 4.20, 95%CI:1.61-10.9, P = 0.003) perceived frailty. Percent agreement between perceived and measured frailty was poor (nephrologist, NP, and patient: 64.1%, 67.0%, and 55.5%). Among non-frail participants, 34.4%, 30.0%, and 31.6% were perceived as frail by a nephrologist, NP, or themselves. Older adults (P < 0.001) were more likely to be misclassified as frail by a nephrologist; women (P = 0.04) and non-African Americans (P = 0.02) were more likely to be misclassified by an NP. Neither age, sex, nor race was associated with patient misclassification. CONCLUSIONS: Perceived frailty is an inadequate proxy for measured frailty among patients undergoing hemodialysis.

Perceptions about hemodialysis and transplantation among African American adults with end-stage renal disease: inferences from focus groups.

BACKGROUND: Disparities in access to kidney transplantation (KT) remain inadequately understood and addressed. Detailed descriptions of patient attitudes may provide insight into mechanisms of disparity. The aims of this study were to explore perceptions of dialysis and KT among African American adults undergoing hemodialysis, with particular attention to age- and sex-specific concerns. METHODS: Qualitative data on experiences with hemodialysis and views about KT were collected through four age- and sex-stratified (males <65, males ≥65, females <65, and females ≥65 years) focus group discussions with 36 African American adults recruited from seven urban dialysis centers in Baltimore, Maryland. RESULTS: Four themes emerged from thematic content analysis: 1) current health and perceptions of dialysis, 2) support while undergoing dialysis, 3) interactions with medical professionals, and 4) concerns about KT. Females and older males tended to be more positive about dialysis experiences. Younger males expressed a lack of support from friends and family. All participants shared feelings of being treated poorly by medical professionals and lacking information about renal disease and treatment options. Common concerns about pursuing KT were increased medication burden, fear of surgery, fear of organ rejection, and older age (among older participants). CONCLUSIONS: These perceptions may contribute to disparities in access to KT, motivating granular studies based on the themes identified.

Frailty, mycophenolate reduction, and graft loss in kidney transplant recipients.

BACKGROUND: Mycophenolate mofetil (MMF) side effects often prompt dose reduction or discontinuation, and this MMF dose reduction (MDR) can lead to rejection and possibly graft loss. Unfortunately, little is known about what factors might cause or contribute to MDR. Frailty, a measure of physiologic reserve, is emerging as an important, novel domain of risk in kidney transplantation recipients. We hypothesized that frailty, an inflammatory phenotype, might be associated with MDR. METHODS: We measured frailty (shrinking, weakness, exhaustion, low physical activity, and slowed walking speed), other patient and donor characteristics, longitudinal MMF doses, and graft loss in 525 kidney transplantation recipients. Time-to-MDR was quantified using an adjusted Cox proportional hazards model. RESULTS: By 2 years after transplantation, 54% of frail recipients and 45% of nonfrail recipients experienced MDR; by 4 years, incidence was 67% and 51%. Frail recipients were 1.29 times (95% confidence interval [95% CI], 1.01-1.66; P = 0.04) more likely to experience MDR, as were deceased donor recipients (adjusted hazard ratio [aHR], 1.92; 95% CI, 1.44-2.54, P < 0.001) and older adults (age ≥ 65 vs <65; aHR, 1.47; 95% CI, 1.10-1.96, P = 0.01). Mycophenolate mofetil dose reduction was independently associated with a substantially increased risk of death-censored graft loss (aHR, 5.24; 95% CI, 1.97-13.98, P = 0.001). CONCLUSION: A better understanding of risk factors for MMF intolerance might help in planning alternate strategies to maintain adequate immunosuppression and prolong allograft survival.

Trends in kidney transplant outcomes in older adults.

OBJECTIVES: To estimate mortality and death-censored graft loss according to year of kidney transplant (KT) between 1990 and 2011. DESIGN: Cohort study. SETTING: The Scientific Registry of Transplant Recipients (SRTR). PARTICIPANTS: KT recipients aged 65 and older at the time of transplantation (N = 30,207). MEASUREMENTS: Mortality and death-censored graft loss ascertained through center report and linkage to Social Security Death Master File and to Medicare. RESULTS: Older adults currently account for 18.4% of KT recipients, up from 3.4% in 1990; similar increases were noted for deceased donor (5.4 times percentage increase) and live donor (9.1 times percentage increase) transplants. Current recipients are not only older, but also more likely to be female and African American, have lengthier pretransplant dialysis, have diabetes mellitus or hypertension, and receive marginal kidneys. Mortality for older deceased donor recipients between 2009 and 2011 was 57% lower (hazard ratio (HR) = 0.43, 95% confidence interval (CI) = 0.33-0.56, P < .001) than between 1990 and 1993; mortality for older live donor recipients was 50% lower (HR = 0.50, 95% CI = 0.36-0.68, P < .001). Death-censored graft loss for older deceased donor recipients between 2009 and 2011 was 65% lower (HR = 0.35, 95% CI = 0.29-0.42, P < .001) than between 1990 and 1993; death-censored graft loss for older live donor recipients was 59% lower (HR = 0.41, 95% CI = 0.24-0.70, P < .001). CONCLUSION: Despite a major increase in number of older adults transplanted and an expanding window of transplant eligibility, mortality and graft loss have decreased substantially for this recipient population. These trends are important to understand for patient counseling and transplant referral.

Health-related and psychosocial concerns about transplantation among patients initiating dialysis.

BACKGROUND AND OBJECTIVES: Disparities in kidney transplantation remain; one mechanism for disparities in access to transplantation (ATT) may be patient-perceived concerns about pursuing transplantation. This study sought to characterize prevalence of patient-perceived concerns, explore interrelationships between concerns, determine patient characteristics associated with concerns, and assess the effect of concerns on ATT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Prevalences of 12 patient-perceived concerns about pursuing transplantation were determined among 348 adults who recently initiated dialysis, recruited from 26 free-standing dialysis centers around Baltimore, Maryland (January 2009-March 2012). Using variable reduction techniques, concerns were clustered into two categories (health-related and psychosocial) and quantified with scale scores. Associations between patient characteristics and concerns were estimated using modified Poisson regression. Associations between concerns and ATT were estimated using Cox models. RESULTS: The most frequently cited patient-perceived concerns were that participants felt they were doing fine on dialysis (68.4%) and felt uncomfortable asking someone to donate a kidney (29.9%). Older age was independently associated with having high health-related (adjusted relative risk, 1.35 [95% confidence interval, 1.20 to 1.51], for every 5 years older for those ≥ 60 years) or psychosocial (1.15 [1.00 to 1.31], for every 5 years older for those aged ≥ 60 years) concerns, as was being a woman (1.72 [1.21 to 2.43] and 1.55 [1.09 to 2.20]), having less education (1.59 [1.08 to 2.35] and 1.77 [1.17 to 2.68], comparing postsecondary education to grade school or less), and having more comorbidities (1.18 [1.08 to 1.30] and 1.18 [1.07 to 1.29], per one comorbidity increase). Having never seen a nephrologist before dialysis initiation was associated with high psychosocial concerns (1.48 [1.01 to 2.18]). Those with high health-related (0.37 [0.16 to 0.87]) or psychosocial (0.47 [0.23 to 0.95]) concerns were less likely to achieve ATT (median follow-up time 2.2 years; interquartile range, 1.6-3.2). CONCLUSIONS: Patient-perceived concerns about pursuing kidney transplantation are highly prevalent, particularly among older adults and women. Reducing these concerns may help decrease disparities in ATT.

Patient- and provider-reported information about transplantation and subsequent waitlisting.

Because informed consent requires discussion of alternative treatments, proper consent for dialysis should incorporate discussion about other renal replacement options including kidney transplantation (KT). Accordingly, dialysis providers are required to indicate KT provision of information (KTPI) on CMS Form-2728; however, provider-reported KTPI does not necessarily imply adequate provision of information. Furthermore, the effect of KTPI on pursuit of KT remains unclear. We compared provider-reported KTPI (Form-2728) with patient-reported KTPI (in-person survey of whether a nephrologist or dialysis staff had discussed KT) in a prospective ancillary study of 388 hemodialysis initiates. KTPI was reported by both patient and provider for 56.2% of participants, by provider only for 27.8%, by patient only for 8.3%, and by neither for 7.7%. Among participants with provider-reported KTPI, older age was associated with lack of patient-reported KTPI. Linkage with the Scientific Registry for Transplant Recipients showed that 20.9% of participants were subsequently listed for KT. Patient-reported KTPI was independently associated with a 2.95-fold (95% confidence interval [95% CI], 1.54 to 5.66; P=0.001) higher likelihood of KT listing, whereas provider-reported KTPI was not associated with listing (hazard ratio, 1.18; 95% CI, 0.60 to 2.32; P=0.62). Our findings suggest that patient perception of KTPI is more important for KT listing than provider-reported KTPI. Patient-reported and provider-reported KTPI should be collected for quality assessment in dialysis centers because factors associated with discordance between these metrics might inform interventions to improve this process.

Age and sex disparities in discussions about kidney transplantation in adults undergoing dialysis.

OBJECTIVES: To explore whether disparities in age and sex in access to kidney transplantation (KT) originate at the time of prereferral discussions about KT. DESIGN: Cross-sectional survey. SETTING: Outpatient dialysis centers in Maryland (n = 26). PARTICIPANTS: Individuals who had recently initiated hemodialysis treatment (N = 416). MEASUREMENTS: Participants reported whether medical professionals (nephrologist, primary medical doctor, dialysis staff) and social group members (significant other, family member, friend) discussed KT with them and, when applicable, rated the tone of discussions. Relative risks were estimated using modified Poisson regression. RESULTS: Participants aged 65 and older were much less likely than those who were younger to have had discussions with medical professionals (44.5% vs 74.8%, P < .001) or social group members (47.3% vs 63.1%, P = .005). Irrespective of sex and independent of race, health-related factors, and dialysis-related characteristics, older adults were more likely not to have had discussions with medical professionals (relative risk (RR) = 1.13, 95% confidence interval (CI) = 1.03-1.24, for each 5-year increase in age through 65; RR = 1.28, 95% CI = 1.14-1.42, for each 5-year increase in age beyond 65). Irrespective of age, women were more likely (RR = 1.45, 95% CI = 1.12-1.89) not to have had discussions with medical professionals. For each 5-year increase in age, men (RR = 1.04, 95% CI = 0.99-1.10) and women (RR = 1.17, 95% CI = 1.10-1.24) were more likely not to have discussions with social group members. Of those who had discussions with medical professionals or social group members, older participants described these discussions as less encouraging (all P < .01). CONCLUSION: Older adults and women undergoing hemodialysis are less likely than younger adults and men to have discussions about KT as a treatment option, supporting a need for better clinical guidelines and education for these individuals, their social network, and their providers.

Actual and perceived knowledge of kidney transplantation and the pursuit of a live donor.

BACKGROUND: Live donor kidney transplantation (LDKT) remains underutilized, partly resulting from the challenges many patients face in asking someone to donate. Actual and perceived kidney transplantation (KT) knowledge are potentially modifiable factors that may influence this process. Therefore, we sought to explore the relationships between these constructs and the pursuit of LDKT. METHODS: We conducted a cross-sectional survey of transplant candidates at our center to assess actual KT knowledge (5-point assessment) and perceived KT knowledge (5-point Likert scale, collapsed empirically to 4 points); we also asked candidates if they had previously asked someone to donate. Associations between participant characteristics and having asked someone to donate were quantified using modified Poisson regression. RESULTS: Of 307 participants, 45.4% were female, 56.4% were non-white race, and 44.6% had previously asked someone to donate. In an adjusted model that included both actual and perceived knowledge, each unit increase in perceived knowledge was associated with 1.21-fold (95% CI: 1.03-1.43, P=0.02) higher likelihood of having asked someone to donate, whereas there was no statistically significant association with actual knowledge (RR=1.08 per unit increase, 95% CI: 0.99-1.18, P=0.10). A conditional forest analysis confirmed the importance of perceived but not actual knowledge in predicting the outcome. CONCLUSIONS: Our results suggest that perceived KT knowledge is more important to a patient's pursuit of LDKT than actual knowledge. Educational interventions that seek to increase patient KT knowledge should also focus on increasing confidence about this knowledge.

Assessment of resident and fellow knowledge of the organ donor referral process.

Maximizing deceased donation rates can decrease the organ shortage. Non-transplant physicians play a critical role in facilitating conversion of potential deceased donors to actual donors, but studies suggest that physicians lack knowledge about the organ donation process. As residency and fellowship are often the last opportunities for formal medical training, we hypothesized that deficiencies in knowledge might originate in residency and fellowship. We conducted a cross-sectional survey to assess knowledge about organ donation, experience in donor conversion, and opinions of the process among residents and fellows after their intensive care unit rotations at the Johns Hopkins Hospital. Of 40 participants, 50% had previously facilitated donor conversion, 25% were familiar with the guidelines of the organ procurement organization (OPO), and 10% had received formal instruction from the OPO. The median score on the knowledge assessment was five of 10; higher knowledge score was not associated with level of medical training, prior training in or experience with donor conversion, or with favorable opinions about the OPO. We identified a pervasive deficit in knowledge among residents and fellows at an academic medical center with an active transplant program that may help explain attending-level deficits in knowledge about the organ donation process.

Frailty and falls among adult patients undergoing chronic hemodialysis: a prospective cohort study.

BACKGROUND: Patients undergoing hemodialysis are at high risk of falls, with subsequent complications including fractures, loss of independence, hospitalization, and institutionalization. Factors associated with falls are poorly understood in this population. We hypothesized that insights derived from studies of the elderly might apply to adults of all ages undergoing hemodialysis; we focused on frailty, a phenotype of physiological decline strongly associated with falls in the elderly. METHODS: In this prospective, longitudinal study of 95 patients undergoing hemodialysis (1/2009-3/2010), the association of frailty with future falls was explored using adjusted Poisson regression. Frailty was classified using the criteria established by Fried et al., as a combination of five components: shrinking, weakness, exhaustion, low activity, and slowed walking speed. RESULTS: Over a median 6.7-month period of longitudinal follow-up, 28.3% of study participants (25.9% of those under 65, 29.3% of those 65 and older) experienced a fall. After adjusting for age, sex, race, comorbidity, disability, number of medications, marital status, and education, frailty independently predicted a 3.09-fold (95% CI: 1.38-6.90, P=0.006) higher number of falls. This relationship between frailty and falls did not differ for younger and older adults (P=0.57). CONCLUSIONS: Frailty, a validated construct in the elderly, was a strong and independent predictor of falls in adults undergoing hemodialysis, regardless of age. Our results may aid in identifying frail hemodialysis patients who could be targeted for multidimensional fall prevention strategies.

Correlates of elevated interleukin-6 and C-reactive protein in persons with or at high risk for HCV and HIV infections.

BACKGROUND: HIV and hepatitis C virus (HCV) infections may increase interleukin-6 (IL-6) and C-reactive protein (CRP). However, relationships between inflammatory biomarkers, chronic viral infections, clinical factors, and behavioral factors remain poorly understood. METHODS: Using linear regression, we modeled cross-sectional associations between loge IL-6 or loge CRP levels and HCV, HIV, injection drug use, and comorbidity among 1191 injection drug users. RESULTS: Mean age was 47 years, 46.0% reported currently injecting drugs, 59.0% were HCV monoinfected, and 27% were HCV/HIV coinfected. In multivariable models, higher loge IL-6 was associated with HCV monoinfection [ß = 0.191, 95% confidence interval (CI): 0.043 to 0.339] and HCV/HIV coinfection (ß = 0.394, 95% CI: 0.214 to 0.574). In contrast, HCV monoinfection (ß = -0.523, 95% CI: -0.275 to -0.789) and HCV/HIV coinfection (ß = -0.554 95% CI: -0.260 to -0.847) were associated with lower CRP. Lower CRP with HCV infection was independent of liver fibrosis severity, synthetic function, or liver injury markers; CRP decreased with higher HCV RNA. Increased injection intensity was associated with higher IL-6 (P = 0.003) and CRP (P < 0.001); increasing comorbidity (P < 0.001) and older age (P = 0.028) were associated with higher IL-6; older age was associated with higher CRP among HCV-uninfected participants (P = 0.021). CONCLUSION: HIV and HCV infections contribute to chronic inflammation; however, reduced CRP possibly occurs through HCV-mediated mechanisms. Findings highlight potentially modifiable contributors to inflammation.

Frailty as a novel predictor of mortality and hospitalization in individuals of all ages undergoing hemodialysis.

OBJECTIVES: To quantify the prevalence of frailty in adults of all ages undergoing chronic hemodialysis, its relationship to comorbidity and disability, and its association with adverse outcomes of mortality and hospitalization. DESIGN: Prospective cohort study. SETTING: Single hemodialysis center in Baltimore, Maryland. PARTICIPANTS: One hundred forty-six individuals undergoing hemodialysis enrolled between January 2009 and March 2010 and followed through August 2012. MEASUREMENTS: Frailty, comorbidity, and disability on enrollment in the study and subsequent mortality and hospitalizations. RESULTS: At enrollment, 50.0% of older (≥ 65) and 35.4% of younger (<65) individuals undergoing hemodialysis were frail; 35.9% and 29.3%, respectively, were intermediately frail. Three-year mortality was 16.2% for nonfrail, 34.4% for intermediately frail, and 40.2% for frail participants. Intermediate frailty and frailty were associated with a 2.7 times (95% confidence interval (CI) = 1.02-7.07, P = .046) and 2.6 times (95% CI = 1.04-6.49, P = .04) greater risk of death independent of age, sex, comorbidity, and disability. In the year after enrollment, median number of hospitalizations was 1 (interquartile range 0-3). The proportion with two or more hospitalizations was 28.2% for nonfrail, 25.5% for intermediately frail, and 42.6% for frail participants. Although intermediate frailty was not associated with number of hospitalizations (relative risk = 0.76, 95% CI = 0.49-1.16, P = .21), frailty was associated with 1.4 times (95% CI = 1.00-2.03, P = .049) more hospitalizations independent of age, sex, comorbidity, and disability. The association between frailty and mortality (interaction P = .64) and hospitalizations (P = .14) did not differ between older and younger participants. CONCLUSIONS: Adults of all ages undergoing hemodialysis have a high prevalence of frailty, more than five times as high as community-dwelling older adults. In this population, regardless of age, frailty is a strong, independent predictor of mortality and number of hospitalizations.

HIV infection, immune suppression, and uncontrolled viremia are associated with increased multimorbidity among aging injection drug users.

BACKGROUND: Despite an increasing burden of age-associated non-AIDS outcomes, few studies have investigated the prevalence or correlates of multimorbidity among aging human immunodeficiency virus (HIV)-infected and epidemiologically comparable at-risk populations. METHODS: Among 1262 AIDS Linked to the IntraVenous Experience (ALIVE) study participants followed in a community-based observational cohort, we defined the prevalence of 7 non-AIDS-defining chronic conditions (diabetes, obstructive lung disease, liver disease, anemia, obesity, kidney dysfunction, and hypertension) using clinical and laboratory criteria. Ordinal logistic regression was used to model the odds of increased multimorbidity associated with demographic, behavioral, and clinical factors. Self-reported prevalence was compared with clinically defined prevalence. RESULTS: Participants were a median of 48.9 years of age; 65.1% were male, 87.5% were African-American, and 28.7% were HIV infected. In multivariable analysis, HIV infection (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.13-1.99) was positively associated with increased multimorbidity. Among HIV-infected participants, multimorbidity was increased with lower nadir CD4 T-cell count (OR, 1.14 per 100-cell decrease; 95% CI, 1.00-1.29) and higher current HIV RNA (OR, 1.32 per log(10) increase; 95% CI, 1.08-1.60). Older age, being female, not using cigarettes or drugs, and having depressive symptoms were also associated with increased multimorbidity. A substantial proportion of multimorbid conditions in HIV-infected and HIV-uninfected participants were unrecognized and untreated. CONCLUSIONS: HIV-infected participants experienced increased numbers of multimorbid conditions; risk increased with advanced immunosuppression and higher viremia. These results underscore the heavy burden of multimorbidity associated with HIV and highlight the need for incorporating routine assessment and integrated management of chronic diseases as part of comprehensive healthcare for aging, HIV-infected persons.

High prevalence of forced sex among non-brothel based, wine shop centered sex workers in Chennai, India.

Sexual violence has been shown to increase women's risk of HIV infection. India is a country where the HIV epidemic is growing among women and intimate partner violence (IPV) is pervasive. This study examined prevalence of and factors associated with forced sex among female sex workers (FSWs) in Chennai, India. We conducted a probability survey among FSWs in 24 slum venues and identified predictive factors for recent forced sex using univariate and multivariable proportional odds models. Among 522 FSWs, 28% reported having forced sex with one partner and 35% with 2+ partners. In the final multivariable model, women who had a high number of partners who had a strong tendency to drink alcohol before sex were more likely to have experienced forced sex, and women who had both unprotected sex with a nonspousal partner and > 20 days of alcohol consumption in the last 30 days were more likely to have experienced forced sex. Discussion about family violence with larger social networks was independently associated with lower odds of forced sex among FSWs. HIV interventions for FSWs and their clients aimed at reducing alcohol consumption and encouraging condom use could be enhanced by violence prevention interventions to facilitate discourse about sexual violence.

Factors associated with the perpetration of sexual violence among wine-shop patrons in Chennai, India.

With an estimated 2.5 million people living with HIV/AIDS, India has the third highest number of HIV-infected people in the world. Despite reductions in prevalence among the general population, the percentage of all infections occurring among Indian women is continuing to rise. Women's risk of HIV infection from their partner and observed associations between sexual violence and HIV infection in India underscore the importance of understanding determinants of forced sex. A probability survey was conducted from June 2003 to August 2007 in Chennai, India, among alcohol venue ("wine shops") patrons to estimate the prevalence of sexual violence and to identify risk factors associated with perpetrating forced sex. Among 1499 men, 28.5% reported forced sex with at least one partner in the past 3 months. In multivariate analysis, earning income for less than 12 months a year, visiting the wine shop with friends, STD symptoms, perpetration of physical violence, and number of sexual partners were statistically significantly associated with perpetrating forced sex. Men who reported having 3 or more close friends were less likely to perpetrate violence. HIV interventions that facilitate formal groups that foster positive social support and address a range of HIV risk behaviors including sexually and physically abusive behaviors are recommended to reduce sexual violence.

Influence of Perceived Secondary Stigma and Family on the Response to HIV Infection Among Injection Drug Users in Vietnam.

The full impact of secondary stigma (stigma directed at family) on an HIV-positive individual is unknown. This qualitative research explores perceptions of secondary stigma in the Vietnamese context and its influence on the ways in which an injection drug user (IDU) copes with HIV infection. Data on experiences learning one's HIV status, disclosure decisions, family reactions, and stigma from family and community were collected through in-depth interviews with 25 HIV-positive IDUs recruited through a health center in Thai Nguyen, Vietnam. Participants felt despair when learning they were HIV-positive and expressed concerns focused on the emotional burden and the consequences of HIV stigma that extended to family. Many participants engaged in self-isolating behaviors to prevent transmission and minimize secondary stigma. Data illustrated the strong value given to family in Vietnam and underscored the importance of secondary stigma in the coping process including gaining social support and engaging in risk reduction.
