OBJECTIVE:To describe the use of Lean in urology at Zuckerberg San Francisco General, a community safety-net and trauma hospital that serves as a major teaching site for the University of California San Francisco. METHODS:We examined our process improvement activities from 2016 to 2018. Our Lean Daily Management System (DMS) includes a 15-minute team huddle ("urology Lean work") of service residents, faculty, clinic and operating room nursing staff, and anesthesia liaisons. Our DMS also includes a 5-minute preoperative huddle. Besides team-building, urology Lean work surfaces logistics, safety or equipment improvement ideas, and ensures progress and completion of initiated projects. RESULTS:Over a 2-year period we developed and completed 67 projects. Projects impacted the outpatient setting (57%), followed by the operating room (22%), the Urology service (12%), and inpatient setting (9%). We completed projects in the following domains: safety (26%), quality (22%), care experience (21%), workforce care and development (13%), equity (11%), and financial stewardship (7%). Urology Lean work reduced new patient clinic access time (119-21 days) and Bacillus Calmette-Guérin in clinic treatment time (180-105 minutes). The average proportion of urology on-time surgeries was better than the overall surgery on-time surgeries (71% v 61%). CONCLUSION/CONCLUSIONS:Urology Lean work successfully applied DMS in a service specific yet holistic approach. Urology Lean work improved resident engagement in quality and safety endeavors and served as a DMS model throughout perioperative and clinic areas.

RATIONALE & OBJECTIVE:Influenza vaccination is recommended for all adults but particularly for older adults and those with high-risk conditions. Reduced kidney function is an important high-risk condition, but the effectiveness of influenza vaccination across kidney function is uncharacterized. We assessed the effectiveness of influenza vaccination among older adults with and without reduced kidney function. STUDY DESIGN:Observational cohort study. SETTING & PARTICIPANTS:454,634 person-seasons among 110,968 individuals 65 years or older in the Geisinger Health System between the 2005 and 2015 influenza seasons, with baseline characteristics matched between those with and without vaccination using inverse probability weighting. EXPOSURES:Status of influenza vaccination. OUTCOMES:). ANALYTICAL APPROACH:Pooled logistic regression analysis to estimate adjusted ORs. RESULTS:(ORs of 1.04 [95% CI, 0.79-1.36] for pneumonia/influenza, 1.03 [95% CI, 0.87-1.23] for coronary heart disease, and 1.10 [95% CI, 0.92-1.33] for heart failure). LIMITATIONS:Possible unmeasured confounding. CONCLUSIONS:.

BACKGROUND:Pubic hair grooming has been correlated with a self-reported history of sexually transmitted infections (STIs). We examined this relationship further in a cross-sectional survey of patients attending an urban STI clinic in San Francisco in 2018. METHODS:Pubic hair grooming practices and detailed sexual histories were obtained. Sexually transmitted infections were confirmed via laboratory diagnosis or physical examination by a licensed provider. RESULTS:A total of 314 individuals completed the survey. The median age of participants was 31 years. In total, there were 247 (80%) men, 58 (19%) women, and 5 (2%) transgender participants. Of the 247 men, 177 (72%) identified as gay or bisexual. Twenty-five (82%) of 314 patients reported pubic hair grooming within the past 3 months. Seventy-eight (25%) patients were diagnosed with a new STI during their visit. There were no significant associations between reporting any anal or genital grooming and being diagnosed with an STI. However, anal groomers were 3 times as likely to be diagnosed with a rectal STI after adjustment (adjusted odds ratio, 3.0; 95% confidence interval, 1.2-7.5) compared with genital only groomers and nongroomers. Participants who report removing all of their pubic hair more than 6 times within the past year had higher prevalence of genital STIs (33.3%, 6-10 times; 28.6%, >10 times) compared with participants who never groom all of their pubic hair (15.3%, P = 0.01). CONCLUSIONS:We found no association between recent grooming and genital STIs. Anal grooming was associated with rectal STIs in gay and bisexual men.

BACKGROUND:Beverages are a source of calories and other bioactive constituents but are an understudied aspect of the diet. Different beverages have varying effects on health outcomes. OBJECTIVES/OBJECTIVE:We created the Healthy Beverage Score (HBS) to characterize participants' beverage patterns and examined its association with chronic kidney disease (CKD) progression, incident cardiovascular disease (CVD), and all-cause mortality among individuals with CKD. METHODS:from the Chronic Renal Insufficiency Cohort. Diet was assessed using a 124-item FFQ at visit 1 (2003-2008). The HBS, ranging from 7 to 28 possible points, consisted of 7 components, each scored from 1 to 4 based on rank distribution by quartile, except alcohol, which was based on sex-specific cutoffs. Participants were given more points for higher consumption of low-fat milk and of coffee/tea, for moderate alcohol, and for lower consumption of 100% fruit juice, whole-fat milk, artificially sweetened beverages, and sugar-sweetened beverages. CKD progression, incident CVD, and mortality were ascertained through January 2018. We conducted multivariable Cox proportional hazards models. RESULTS:-trend = 0.04) after adjusting for sociodemographic, clinical, and dietary factors. There was no significant trend for incident CVD. CONCLUSIONS:Among individuals with CKD, a healthier beverage pattern was inversely associated with CKD progression and all-cause mortality. Beverage intake may be an important modifiable target in preventing adverse outcomes for individuals with CKD.

BACKGROUND:As more older adults undergo surgery, it is critical to understand the long-term effects of surgery on brain health, particularly in relation to the development of Alzheimer's disease. This study examined the association of surgical hospitalization with subsequent brain β-amyloid deposition in nondemented older adults. METHODS:The Atherosclerosis Risk in Communities-Positron Emission Tomography (ARIC-PET) study is a prospective cohort study of 346 participants without dementia who underwent florbetapir PET imaging. Active surveillance of local hospitals and annual participant contact were used to gather hospitalization and surgical information (International Classification of Disease, Ninth Revision, Clinical Modification codes) over the preceding 24-yr period. Brain amyloid measured using florbetapir PET imaging was the primary outcome. Elevated amyloid was defined as a standardized uptake value ratio of more than 1.2. RESULTS:Of the 313 participants included in this analysis (age at PET: 76.0 [SD 5.4]; 56% female), 72% had a prior hospitalization, and 50% had a prior surgical hospitalization. Elevated amyloid occurred in 87 of 156 (56%) participants with previous surgical hospitalization, compared with 45 of 87 (52%) participants who had no previous hospitalization. Participants with previous surgical hospitalizations did not show an increased odds of elevated brain amyloid (odds ratio, 1.32; 95% CI, 0.72 to 2.40; P = 0.370) after adjusting for confounders (primary analysis). Results were similar using the reference group of all participants without previous surgery (hospitalized and nonhospitalized; odds ratio, 1.58; 95% CI, 0.96 to 2.58; P = 0.070). In a prespecified secondary analysis, participants with previous surgical hospitalization did demonstrate increased odds of elevated amyloid when compared with participants hospitalized without surgery (odds ratio, 2.10; 95% CI, 1.09 to 4.05; P = 0.026). However, these results were attenuated and nonsignificant when alternative thresholds for amyloid-positive status were used. CONCLUSIONS:The results do not support an association between surgical hospitalization and elevated brain amyloid.

OBJECTIVE:Incorporation of comorbidity burden to inform diabetes management in older adults remains challenging. High-sensitivity cardiac troponins are objective, quantifiable biomarkers that may improve risk monitoring in older adults. We assessed the associations of elevations in high-sensitivity cardiac troponin I (hs-cTnI) and T (hs-cTnT) with comorbidities and improvements in mortality risk stratification. RESEARCH DESIGN AND METHODS:We used logistic regression to examine associations of comorbidities with elevations in either troponin (≥85th percentile) among 1,835 participants in the Atherosclerosis Risk in Communities (ARIC) Study with diabetes (ages 67-89 years, 43% male, 31% black) at visit 5 (2011-2013). We used Cox models to compare associations of high cardiac troponins with mortality across comorbidity levels. RESULTS:Elevations in either troponin (≥9.4 ng/L for hs-cTnI, ≥25 ng/L for hs-cTnT) were associated with prevalent coronary heart disease, heart failure, chronic kidney disease, pulmonary disease, hypoglycemia, hypertension, dementia, and frailty. Over a median follow-up of 6.2 years (418 deaths), both high hs-cTnI and high hs-cTnT further stratified mortality risk beyond comorbidity levels; those with a high hs-cTnI or hs-cTnT and high comorbidity were at highest mortality risk. Even among those with low comorbidity, a high hs-cTnI (hazard ratio 3.0 [95% CI 1.7, 5.4]) or hs-cTnT (hazard ratio 3.3 [95% CI 1.8, 6.2]) was associated with elevated mortality. CONCLUSIONS:Many comorbidities were reflected by both hs-cTnI and hs-cTnT; elevations in either of the troponins were associated with higher mortality risk beyond comorbidity burden. High-sensitivity cardiac troponins may identify older adults at high mortality risk and be useful in guiding clinical care of older adults with diabetes.

A crisis of mass immigration detention exists in the United States, which is home to the world's largest immigration detention system. The immigration detention system is legally classified as civil, rather than criminal, and therefore non-punitive. Yet it mimics the criminal incarceration system and holds detained individuals in punitive, prison-like conditions. Within immigration detention centers, there are increasing reports and recognition of civil and human rights abuses, including preventable in-custody deaths. In this paper, we propose understanding the health impacts of detention as an accumulation of mental and physical trauma that take place during the entirety of a detained immigrant's experience, from migration to potential deportation and removal. Further, we explore the social-structural determinants of health as they relate to immigration detention, contextualize these determinants within a human rights framework, and draw parallels to the larger context of US mass incarceration. Realizing the right to health requires addressing these social-structural determinants of health. For the care of immigrant patients to be effective, clinicians and public health professionals must incorporate an awareness of the health risks of the immigration detention system into trauma- and human rights-informed models of care during and after detention.

Purpose: Almost uniformly, patients with frequent Emergency Department (ED) use and severe alcohol use disorders (AUDs) do not receive alcohol pharmacotherapy and are excluded from research as they are difficult to engage and retain and suffer from myriad bio-psychosocial comorbidities. We assessed the feasibility and acceptability of initiating and continuing treatment with extended-release naltrexone (XR-NTX) as well as studying its effects in this challenging population and clinical setting.
Method(s): In this randomized, open-label study, ED patient-participants with > 4 ED visits and moderate- severe AUD were randomized (1:1) to XR-NTX and research assistant-delivered care management or treatment as usual enhanced by a one-time warm referral and motivation enhancement. XR-NTX was first administered during the index ED visit. Thereafter, participants could receive up to 11 additional doses at clinic visits with arrangements to allow unscheduled visits. Non-clinical research visits (both arms) were scheduled at 3, 6, and 12 months with a considerable date variation permitted and expected. Drinking was assessed via 30-day timeline followback with heavy drinking day (HDD) thresholds of 5 for males and 4 for females. Resuts: The 48 participants were aged 55.0 +/- 8.2, 88% male, 51% white, 79% homeless, and reported an average of 23.4 HDDs in the priormonth and 24.4 standard drinks/drinking day. Approximately 70%lacked reliable contact information. Research visit attendance was 70.8%, 77.1%, and 70.8%with a median time to first visit of 126 days [Interquartile Range: 89-242]. In the XR-NTX arm (N = 24), a total of 173 injections were administered with amean of 7.2 per participant; 20 (83%) participants received 2 or more injections, 14 (56%) received 6 or more injections, and 6 (24%) received 12 injections. There was a significantly greater decrease in HDDs per month among those receiving XR-NTX compared to those who did not: 15.3 (95%CI 9.7-21.0) and 9.6 (95%CI 1.5-17.6), respectively. Baseline rates were imputed for two missing participants in each arm.
Conclusion(s): Among this population whose complicated AUDs pose considerable challenges from clinical and research perspectives, initiating and continuing treatment with XR-NTX was feasible, acceptable, and demonstrated promising preliminary drinking outcomes. Additional sensitivity analyses and evaluation of other outcomes of interest are underway. Further study on a larger scale is warranted

Introduction/UNASSIGNED:-nephropathy. Methods/UNASSIGNED:A global gene expression analysis was performed in human primary renal tubule cell lines derived from 50 African American individuals. Follow-up gene knock out, cell-based rescue, and microscopy experiments were performed. Results/UNASSIGNED:G0, G1, and G2 were created; G0 cells appeared to promote mitochondrial fusion, whereas G1 and G2 induced mitochondrial fission. The mitochondrial dynamic regulator Mdivi-1 significantly preserved cell viability and mitochondrial cristae structure and reversed mitochondrial fission induced by overexpression of G1 and G2. Conclusion/UNASSIGNED:-nephropathy.
