BACKGROUND:Adherence to healthy dietary patterns, measured by the Healthy Eating Index (HEI), Alternative Healthy Eating Index (AHEI), and alternate Mediterranean diet (aMed) scores, is associated with a reduced risk of cardiovascular disease. The association between these scores and chronic kidney disease (CKD) is undetermined. OBJECTIVE:We aimed to estimate the association between the HEI, AHEI, and aMed scores and risk of incident CKD. METHODS:We conducted a prospective analysis in 12,155 participants aged 45-64 y from the Atherosclerosis Risk in Communities (ARIC) Study. We calculated HEI-2015, AHEI-2010, and aMed scores for each participant and categorized them into quintiles of each dietary score. Incident CKD was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m2 accompanied by ≥25% decline in estimated glomerular filtration rate, a kidney disease-related hospitalization or death, or end-stage renal disease. We used cause-specific hazard models to estimate risk of CKD from the quintile of the dietary score through to 31 December 2017. RESULTS:There were 3980 cases of incident CKD over a median follow-up of 24 y. Participants who had higher adherence to the HEI-2015, AHEI-2010, and aMed scores were more likely to be female, have higher educational attainment, higher income level, be nonsmokers, more physically active, and diabetic compared with participants who scored lower. All 3 dietary scores were associated with lower CKD risk (P-trend < 0.001). Participants who were in the highest quintile of HEI-2015 score had a 17% lower risk of CKD (HR: 0.83; 95% CI: 0.74, 0.92) compared with participants in the lowest quintile. Those in quintile 5 of AHEI-2010 and aMed scores, respectively, had a 20% and 13% lower risk of CKD compared with those in quintile 1. CONCLUSION:Higher adherence to healthy dietary patterns during middle age was associated with lower risk of CKD.

Our objective was to examine associations of head injury with total and regional brain amyloid deposition. We performed cross-sectional analyses of 329 non-demented participants (81 with prior head injury) in the Atherosclerosis Risk in Communities-Positron Emission Tomography (ARIC-PET) Study who underwent ^18-florbetapir PET imaging in 2012-2014. A history of head injury was defined by self-report or emergency department/hospitalization International Classification of Diseases, Ninth Revision codes. Generalized linear regression models adjusted for demographic, socioeconomic, and dementia/cardiovascular risk factors were used to estimate prevalence ratios (PRs; 95% confidence intervals [CIs]) for elevated (> 1.2) global and regional standard uptake value ratios (SUVRs). Mean age of participants was 76 years, 57% were women, and 43% were black. Head injury was associated with increased prevalence of elevated SUVR >1.2 globally (PR: 1.31; 95% CI: 1.19-1.57), as well as in the orbitofrontal cortex (PR: 1.23); (95% CI: 1.04-1.46), prefrontal cortex (PR: 1.18; 95% CI: 1.00-1.39), superior frontal cortex (PR: 1.24; 95% CI: 1.05-1.48), and posterior cingulate (PR: 1.26; 95% CI: 1.04-1.52). There also was evidence for a dose-response relationship, whereby a history of ≥1 head injury was associated with elevated SUVR >1.2 in the prefrontal cortex and superior frontal cortex compared with persons with a history of one head injury (all, p < 0.05). In conclusion, head injury was associated with increased amyloid deposition globally and in the frontal cortex and posterior cingulate, with suggestion of a dose-response association of head injuries with beta-amyloid deposition. Further work is needed to determine if increased amyloid deposition contributes to dementia in this population.

BACKGROUND:Patients with active cancer account for a growing percentage of all emergency department (ED) visits and have a unique set of risks related to their disease and its treatments. Effective triage for this population is fundamental to facilitating their emergency care. OBJECTIVES/OBJECTIVE:We evaluated the validity of the Emergency Severity Index (ESI; version 4) triage tool to predict ED-relevant outcomes among adult patients with active cancer. METHODS:tests for independence to relate ESI scores with 1) disposition, 2) ED resource use, 3) hospital length of stay, and 4) 30-day mortality. RESULTS:Among the 1008 subjects included in this analysis, the ESI distribution skewed heavily toward high acuity (>95% of subjects had an ESI level of 1, 2, or 3). ESI was significantly associated with patient disposition and ED resource use (p values < 0.05). No significant associations were observed between ESI and the non-ED based outcomes of hospital length of stay or 30-day mortality. CONCLUSION/CONCLUSIONS:ESI scores among ED patients with active cancer indicate higher acuity than the general ED population and are predictive of disposition and ED resource use. These findings show that the ESI is a valid triage tool for use in this population for outcomes directly relevant to ED care.

BACKGROUND:Decline in eGFR is a biologically plausible surrogate end point for the progression of CKD in clinical trials. However, it must first be tested to ensure strong associations with clinical outcomes in diverse populations, including patients with higher eGFR. METHODS:from 14 cohorts followed for an average of 4.2 years. RESULTS:per year over 2 years would reduce the ESKD risk by 1.6%. For a hypothetical low-risk population with a predicted 5-year ESKD risk of 0.58%, the same intervention would reduce the risk by only 0.13%. CONCLUSIONS:, but those with the highest risk would be expected to benefit the most.

The incidence of intramural hematomas (IMH) in acute dissection (AD) patients varies between 6% and 30% in the literature, most frequently involving only the descending aorta (58%) than the arch or ascending aorta (42%). In this setting, IMH that initiate in the descending aorta, but extend into the arch or ascending aorta have been described, and referred to as a retrograde type A IMH. In these patients the risk of neurological or cardiac complications are high, and therefore an open surgical or hybrid approach has been proposed as the most appropriate. Nevertheless, the endovascular management of such lesions in surgically unfit patients for open surgery have been offered with acceptable outcomes, although the risk of landing in an unsuitable proximal landing zone is evident. In conclusion, retro-TAIMH is an acute aortic syndrome and should be managed as such. The recommended treatment strategy is open surgery for treating ascending or arch involvement, and TEVAR/medical, based on a complication-specific approach, for those with only descending localization. In those patients in whom retro-TAIMH is associated with an acute B dissection presenting with a proximal entry tear located into the descending aorta, a TEVAR represents an option treatment.

PURPOSE:Some patients continue to have bothersome lower urinary tract symptoms despite treatment. We examined characteristics associated with bother from lower urinary tract symptoms in a prospective cohort. MATERIALS AND METHODS:In this 1-year prospective, observational cohort study we obtained data on patients with lower urinary tract symptoms who were seeking care at a total of 6 tertiary care centers in the United States. Participants answered the AUA-SI (American Urological Association Symptom Index) global urinary bother question at study entry and 12 months later. Multilevel logistic and linear regression was used to identify factors associated with worsening bother and bother at 12 months, respectively. RESULTS:Of the 756 participants 121 (16%) had worsened lower urinary tract symptom bother during the study period. When adjusted for other variables, worsened lower urinary tract symptom bother was more likely among men who were nonwhite (OR 1.79, 95% CI 0.94-3.40) or who had diabetes (OR 1.68, 95% CI 0.86-3.27) and among women with diabetes (OR 1.77, 95% CI 0.85-3.67), prior treatment of lower urinary tract symptoms (OR 2.58, 95% CI 1.22-5.46) or a higher depression level (OR 1.29, 95% CI 1.10-1.52). Baseline factors associated with more severe bother at 12 months in men included more severe bother at baseline, nonwhite race, worse urinary frequency and incontinence, and higher levels of stress (p <0.05). Among women more severe bother at baseline, urinary urgency and frequency, and worse physical function were associated with more severe bother at 12 months. CONCLUSIONS:Urinary symptom severity at baseline, race, depression and psychological stress were associated with the bother of lower urinary tract symptoms in a prospective cohort of men and women treated at tertiary care facilities. These findings may inform the clinical care of patients with bothersome lower urinary tract symptoms and direct providers to better prognosticate for patients with challenging lower urinary tract symptoms cases.

PURPOSE/OBJECTIVE:Research among adults shows benefits and low perceived burden of engaging in behavioral research. However, questions remain regarding the ethics of conducting behavioral research in pediatric populations during sensitive situations, including during a new life-threatening diagnosis or at end-of-life. We examined reactions to participating in a behavioral reproductive research study among male adolescents newly diagnosed with cancer and their parents, as a step towards optimizing fertility preservation utilization in a population where future infertility is common. METHODS:Pediatric literature regarding the ethics of behavioral research was reviewed. In our pilot, forty-four participants (19 mothers, 11 fathers, 14 male adolescents newly diagnosed with cancer) from 20 families completed demographic questionnaires and a fertility preservation decision tool developed by the study team. Qualitative interviews exploring the impact of study participation were subsequently conducted. Verbatim transcripts were coded for thematic content using the constant comparison method. RESULTS:Literature review showed positive reactions to research participation among youth/caregivers. In our pilot study, 89% (n = 17) of mothers, 64% (n = 7) of fathers, and 71% (n = 10) of adolescents reported at least one benefit of participating. Eleven percent (n = 2) of mothers, 36% (n = 4) of fathers, and 29% (n = 4) of adolescents said they were not affected; none of the participants reported a negative effect. CONCLUSION/CONCLUSIONS:Consistent with prior literature, our study suggests behavioral reproductive research prior to cancer treatment can offer direct benefits to participants and society, without increasing burden. These findings will inform future interventions to improve long-term psychosocial and reproductive outcomes for youth with cancer.

This paper describes a mental health capacity-building partnership between the University of Nairobi (UON) and the University of Washington (UW) that was built upon a foundational 30-year HIV/AIDS research training collaboration between the two institutions. With funding from the US National Institute of Mental Health Medical Education Program Initiative (MEPI), UW and UON faculty collaborated to develop and offer a series of workshops in research methods, grant writing, and manuscript publication for UON faculty and post-graduate students committed to mental health research. UON and UW scientists provided ongoing mentorship to UON trainees through Skype and email. Three active thematic research groups emerged that focused on maternal and child mental health, gender-based violence, and HIV-related substance abuse. Challenges to conducting mental health research in Kenya included limited resources to support research activities, heavy teaching responsibilities, clinical duties, and administrative demands on senior faculty, and stigmatization of mental health conditions, treatment, and research within Kenyan society. The partnership yielded a number of accomplishments: a body of published papers and presentations at national and international meetings on Kenyan mental health topics, the institution of systematic mental health data collection in rural clinics, funded research proposals, and a mental health research resource centre. We highlight lessons learned for future mental health research capacity-building initiatives.

BACKGROUND:Metabolic Syndrome (MetSyn) predicted future development of World Trade Center lung injury(WTC-LI) in a subgroup of never smoking, male firefighters. An intra-cohort validation of MetSyn as predictors of WTC-LI is examined in the WTC-exposed cohort that has been longitudinally followed for 16 years. METHODS:<LLN. RESULTS:Cases were more likely to smoke, be highly exposed, and have MetSyn. There was a significant exposure dose response; the most highly-exposed individuals had 30.1%-increased risk of developing WTC-LI; having MetSyn increased risk of WTC-LI by 55.7%; smoking increased risk by 15.2%. There was significant interaction between smoking and exposure. CONCLUSIONS:We validated the utility of MetSyn to predict future WTC-LI in a larger population of exposed individuals. MetSyn defined by dyslipidemia, insulin resistance, and cardiovascular disease suggests that systemic inflammation can contribute to future lung function loss.

Objective: Epidemiologic studies have found that a greater degree of comorbidity is associated with worse fertility potential. However, these findings are largely based on retrospective studies of men interacting with the health care system. Our objective was to evaluate the association of fertility and health status in men in the United States using a nationally representative survey.
Design(s): We compared the demographics, healthcare utilization, and overall health status of fertile and infertile men in the National Survey for Family Growth (NSFG).
Material(s) and Method(s): We performed an analysis of the male 2011-2017 cycles of the NSFG, a nationally representative survey of family planning. Infertile men were defined as men who had ever used infertility services or men who self-reported as non-surgically sterile. Men who reported completed pregnancies were considered fertile.
Result(s): Of the 13,861 men surveyed, 1,071 men were infertile, and 5,661 men were known to be fertile. Projecting to the national population, this translates to 5,205,771 infertile men and a 26,577,702 fertile men. Of the total population of sexually active men aged 15-49, roughly 8.5% (95%CI: 7.8-9.3) of men were infertile. Compared to known fertile men, infertile men had significant demographic and healthcare utilization differences (Table). Infertile men were wealthier, better educated, more likely to be white, more likely to be married, and more likely to have private insurance. Importantly, infertile men and fertile men had similar overall health status. On multivariate analysis, differences in income, marital status, and usual healthcare place remained significant.
Conclusion(s): While infertile men do have significant demographic and healthcare utilization differences compared to fertile men, the overall health status of both infertile and fertile men appear similar. [Figure presented]
