Abstract We aimed to evaluate associations of baseline telomere length with overall and annual change in estimated glomerular filtration rate (eGFR) and trajectory of kidney function during an 8-year follow-up. A total of 3,964 participants of the Health and Retirement Study (HRS) were included. We identified three trajectory groups of kidney function: consistently normal (n=1,163 or 29.3%), normal to impaired (n=2,306 or 58.2%), and consistently impaired groups (n=495 or 12.5%). After controlling for age, sex, race, education, smoking, drinking, diabetes, heart disease, blood pressure, body mass index, total cholesterol, and hemoglobin A1c, participants with longer telomere length were 20% less likely (odds ratio [OR]=0.80, 95% confidence interval [CI]: 0.69-0.93, P=0.003) to have a normal to impaired kidney function trajectory than a consistently normal function trajectory. Telomere length was not associated with changing rate of eGFR over 8 years (P=0.45). Participants with longer telomere length were more likely to have consistently normal kidney function.

Abstract Background With advancing age, there is an increase in the time of and number of experiences with psychosocial stressors that may lead to the initiation and/or progression of chronic kidney disease (CKD). Our study tests whether one type of experience, everyday discrimination, predicts kidney function among middle and older adults. Methods The data were from 10 973 respondents (ages 52–100) in the 2006/2008 Health and Retirement Study, an ongoing biennial nationally representative survey of older adults in the United States. Estimated glomerular filtration rate (eGFR) derives from the Chronic Kidney Disease Epidemiology Collaboration equation. Our indicator of everyday discrimination is drawn from self-reports from respondents. Ordinary Least Squared regression (OLS) models with robust standard errors are applied to test hypotheses regarding the link between everyday discrimination and kidney function. Results Everyday discrimination was associated with poorer kidney function among respondents in our study. Respondents with higher everyday discrimination scores had lower eGFR after adjusting for demographic characteristics (B = −1.35, p < .05), and while attenuated, remained significant (B = −0.79, p < .05) after further adjustments for clinical, health behavior, and socioeconomic covariates. Conclusions Our study suggests everyday discrimination is independently associated with lower eGFR. These findings highlight the importance of psychosocial factors in predicting insufficiency in kidney function among middle-aged and older adults.

Background: Persons with morbid obesity are at increased risk for end-stage kidney disease, and prior studies have shown an association between bariatric surgery and improvements in creatinine-based estimated glomerular filtration rate (eGFR cr ). However, eGFR cr could be biased by loss of muscle mass after surgery, and creatinine-cystatin C estimated glomerular filtration rate (eGFR cr-cyc ) has been shown to be more accurate in this setting. Methods: We matched 144 patients who underwent bariatric surgery on pre-surgery age, sex, race, body mass index (BMI), and eGFR cr with 144 morbidly obese non-surgery patients at Geisinger with serial biobanked serum samples. We measured filtration markers (creatinine, cystatin C, beta-2 microglobulin [B2M] and beta-trace protein [BTP], and calculated eGFR cr-cyc using the CKD-EPI combined equation. Using mixed effects models with random intercepts, we compared changes in filtration markers and eGFR cr-cyc between surgery and non-surgery groups. Results: Mean (SD) values for age, BMI, and eGFR cr were 48.2 (10.4) years, 45.2 (6.3) kg/m 2 , and 91.7 (17.5) ml/min/1.73m 2 ; 87.5% were female, 0.7% were black, 50.3% had hypertension, and 41.0% had type 2 diabetes. Mean eGFR cr-cyc slope in the surgery group was -0.41 ml/min/1.73m 2 /yr (95% CI: -0.74, -0.08) over a mean follow-up of 9.2 (1.4) years, compared to -1.43 ml/min/1.73m 2 /yr in the non-surgery group over a mean follow-up of 8.2 (1.1) years. Bariatric surgery was associated with a 1.02 ml/min/1.73m 2 /yr slower decline in eGFR cr-cyc , and smaller increase in all 4 filtration markers (p< 0.02 for all comparisons). Conclusions: Bariatric surgery is associated with slower decline in kidney function, as assessed by eGFR cr-cyc , B2M and BTP.

AbstractExperience of stressful life events is associated with risk of depression. Yet many exposed individuals do not become depressed. A controversial hypothesis is that genetic factors influence vulnerability to depression following stress. This hypothesis is most commonly tested with a “diathesis-stress” model, in which genes confer excess vulnerability. We tested an alternative model, in which genes may buffer against the depressogenic effects of life stress. We measured the hypothesized genetic buffer using a polygenic score derived from a published genome-wide association study (GWAS) of subjective wellbeing. We tested if married older adults who had higher polygenic scores were less vulnerable to depressive symptoms following the death of their spouse as compared to age-peers who had also lost their spouse and who had lower polygenic scores. We analyzed data from N=9,453 non-Hispanic white adults in the Health and Retirement Study (HRS), a population-representative longitudinal study of older adults in the United States. HRS adults with higher wellbeing polygenic scores experienced fewer depressive symptoms during follow-up. Those who survived death of their spouses during follow-up (n=1,829) experienced a sharp increase in depressive symptoms following the death and returned toward baseline over the following two years. Having a higher polygenic score buffered against increased depressive symptoms following a spouse's death. Effects were small and clinical relevance is uncertain, although polygenic score analyses may provide clues to behavioral pathways that can serve as therapeutic targets. Future studies of gene-environment interplay in depression may benefit from focus on genetics discovered for putative protective factors.

Abstract Background Body mass index (BMI) is linked to Type 2 diabetes (T2D). Although romantic partners influence each other's health outcomes, it is unclear if partner's BMI is related to the development of T2D. Purpose To test prospective, dyadic associations between BMI and the development of T2D in middle-aged and older adult couples over 8 years. Methods Data came from 950 couples in the Health and Retirement Study. Neither partner had diabetes at baseline (2006). The actor–partner interdependence model was used to examine dyadic associations between BMI at baseline and the development of T2D during the next 8 years. Results After adjusting for covariates, a significant actor effect was observed such that one's BMI at baseline was positively associated with one's own odds of developing T2D during follow-up (odds ratio [OR] = 1.08, p &lt; .001). A significant partner effect was also observed such that the BMI of one's partner at baseline was positively associated with one's own odds of developing T2D during follow-up above and beyond one's own baseline BMI (OR = 1.04, p = .003). These associations were not moderated by sex. This pattern of results held when BMI was coded categorically (not overweight/obese; overweight; obese). Conclusions Partner's BMI was prospectively associated with the likelihood of developing T2D. Future research should consider interpersonal risk factors for chronic health conditions, such as T2D. There is an opportunity to develop theoretical models that specify how and when partner characteristics are linked to physical morbidity.

Background. Loneliness and social isolation are emerging public health challenges for aging populations. Methods. We followed N=11,305 US Health and Retirement Study (HRS) participants aged 50-95 from 2006-2014 to measure persistence of exposure to loneliness and social isolation. We tested associations of longitudinal loneliness and social-isolation phenotypes with disability, morbidity, mortality, and biological aging through 2018. Results. During follow-up, 18% of older adults met criteria for loneliness and, for 6%, symptoms persisted across two or more follow-up assessments. For social isolation, these fractions were 21% and 8%. HRS participants who experienced loneliness and social isolation were at increased risk for disease, disability, and mortality. Older adults experiencing persistent loneliness were at a 59% increased hazard of mortality compared to those who were never lonely. For social isolation, the increase was 28%. Effect-sizes were somewhat larger for counts of prevalent activity limitations and somewhat smaller for counts of prevalent chronic diseases. Covariate adjustment for socioeconomic and psychological risks attenuated but did not fully explain associations. Older adults who experienced loneliness and social isolation also exhibited physiological indications of advanced biological aging (Cohen's-d for persistent loneliness and social isolation=0.26 and 0.21, respectively). For loneliness, but not social isolation, persistence of symptoms was associated with increased risk. Conclusion. Deficits in social connectedness prevalent in a national sample of older adults in the US were associated with morbidity, disability, and mortality and with more advanced biological aging. Bolstering social connection to interrupt experiences of loneliness may promote healthy aging.

Abstract Background Patients with primary hyperparathyroidism (pHPT) and impaired kidney function (estimated glomerular filtration rate (eGFR) < 60 mL/min) are offered parathyroidectomy (PTX) to protect them from further complications. Surprisingly, two recent uncontrolled cohort studies have suggested a further decrease in kidney function following PTX. We aimed to examine the effects of PTX compared to non-surgical surveillance on kidney function in pHPT patients. Methods Historic cohort study. From the Danish National Patient Registry (NPR) and major medical biochemistry laboratories in Denmark, we identified 3585 patients with biochemically confirmed pHPT among whom n = 1977 (55%) were treated with PTX (PTX-group) whereas n = 1608 (45%) were followed without surgery (non-PTX group). Baseline was defined as time of diagnosis and kidney function was re-assessed 9–15 months after PTX (PTX group) or 9–15 months after diagnosis (non-PTX group). Results At follow-up, eGFR had decreased significantly in the PTX- compared to the non-PTX-group (median − 4% vs. − 1%, p < 0.01). Stratification by baseline eGFR showed that the decrease was significant for those with a baseline eGFR value of 80–89 and > 90 mL/min, but not for those with lower eGFR values. Findings did not differ between patients with mild compared to moderate/severe hypercalcemia. However, after mutual adjustments, we identified baseline levels of calcium, PTH, and eGFR as well as age and treatment (PTX vs. no-PTX) as independent predictors for changes in kidney function. Conclusion Compared to non-surgical surveillance, PTX is associated with a small but significant decrease in kidney function in pHPT patients with an initial normal kidney function.
