OBJECTIVE:To determine the degree of contemporary practice variation for the treatment of urethral stricture disease (USD) given repeated endoscopic management yields poor long-term success. MATERIALS AND METHODS/METHODS:The AUA Quality (AQUA) Registry collects data from participating urologists across practice settings by direct interface with local electronic health record systems. We identified procedures used for USD using Current Procedural Terminology (CPT) and International Statistical Classification of Diseases (ICD-9/-10) codes. We assessed the association between patient and provider factors and repeated endoscopic treatment using generalized linear models. Provider details were derived from AUA Census. RESULTS:We identified 20,640 male patients with USD treated surgically in AQUA from 2014-2018. The patients were cared for by 1343 providers at 171 practices, 95% of these community-based. Among patients with USD who had treatment, 20,101(97.9%) underwent endoscopic management. 6218(31%) underwent repeated endoscopic treatment during the study period. Urethroplasty was performed in 539(2.6%) patients.  Median patient age at first procedure for endoscopic surgery vs. urethroplasty was 73 vs. 39 years old, respectively (p<0.001). At the practice level, significant variation in rates of repeated endoscopic management was noted. Patients of older age (OR=1.08, 95%CI: 1.06-1.11 for ages ≥80) and patients with a bladder cancer diagnosis (OR=1.17, 95%CI: 1.15-1.20) had higher odds of receiving repeated endoscopic management. Increasing practitioner age was also associated with increased odds of repeated endoscopic management. (OR=1.13, 95%CI: 1.11- 1.16, for practitioners ≥64). CONCLUSIONS:Repeated endoscopic management for USD is overused. The utilization of endoscopic management is variable across practices and frequently guideline-discordant, presenting an opportunity for quality improvement.

OBJECTIVES/OBJECTIVE:Hyponatremia occurs in up to 30% of patients with pneumonia and is associated with increased morbidity and mortality. The prevalence of hyponatremia associated with coronavirus disease 2019 and the impact on outcome is unknown. We aimed to identify the prevalence, predictors, and impact on outcome of mild, moderate, and severe admission hyponatremia compared with normonatremia among coronavirus disease 2019 patients. DESIGN/METHODS:Retrospective, multicenter, observational cohort study. SETTING/METHODS:Four New York City hospitals that are part of the same health network. PATIENTS/METHODS:Hospitalized, laboratory-confirmed adult coronavirus disease 2019 patients admitted between March 1, 2020, and May 13, 2020. INTERVENTIONS/METHODS:None. MEASUREMENTS AND MAIN RESULTS/RESULTS:Hyponatremia was categorized as mild (sodium: 130-134 mmol/L), moderate (sodium: 121-129 mmol/L), or severe (sodium: ≤ 120 mmol/L) versus normonatremia (135-145 mmol/L). The primary outcome was the association of increasing severity of hyponatremia and in-hospital mortality assessed using multivariable logistic regression analysis. Secondary outcomes included encephalopathy, acute renal failure, mechanical ventilation, and discharge home compared across sodium levels using Kruskal-Wallis and chi-square tests. In exploratory analysis, the association of sodium levels and interleukin-6 levels (which has been linked to nonosmotic release of vasopressin) was assessed. Among 4,645 patient encounters, hyponatremia (sodium < 135 mmol/L) occurred in 1,373 (30%) and 374 of 1,373 (27%) required invasive mechanical ventilation. Mild, moderate, and severe hyponatremia occurred in 1,032 (22%), 305 (7%), and 36 (1%) patients, respectively. Each level of worsening hyponatremia conferred 43% increased odds of in-hospital death after adjusting for age, gender, race, body mass index, past medical history, admission laboratory abnormalities, admission Sequential Organ Failure Assessment score, renal failure, encephalopathy, and mechanical ventilation (adjusted odds ratio, 1.43; 95% CI, 1.08-1.88; p = 0.012). Increasing severity of hyponatremia was associated with encephalopathy, mechanical ventilation, and decreased probability of discharge home (all p < 0.001). Higher interleukin-6 levels correlated with lower sodium levels (p = 0.017). CONCLUSIONS:Hyponatremia occurred in nearly a third of coronavirus disease 2019 patients, was an independent predictor of in-hospital mortality, and was associated with increased risk of encephalopathy and mechanical ventilation.

OBJECTIVE:To evaluate the health status of men who have undergone vasectomy versus nonsterilized fertile men. METHODS:Using the National Survey for Family Growth from 2002 to 2017, univariate and multivariate analyses were performed on demographic and health data, including health status and health care utilization. RESULTS:Men who have undergone vasectomy are more likely to be older, healthier, have more children, identify as non-Hispanic white, be married, have a higher level of education, earn a higher mean household income, and were more likely to be privately insured than non-sterilized fertile men. On multivariate analysis, men who underwent vasectomy had a better health status despite being older. CONCLUSION/CONCLUSIONS:There are significant socioeconomic and health differences between men who elect vasectomy and non-sterilized fertile men. These differences should be considered when considering using sterilized men as a proxy for proven fertile men in epidemiological studies.

BACKGROUND:Powered, two-wheeled transportation devices like electric bicycles (E-bikes) and scooters are increasingly popular, but little is known about their relative injury risk compared to pedal operated bicycles. METHODS:Descriptive and comparative analysis of injury patterns and trends associated with E-bikes, powered scooters and pedal bicycles from 2000 to 2017 using the US National Electronic Injury Surveillance System. RESULTS:While persons injured using E-bikes were more likely to suffer internal injuries (17.1%; 95% CI 5.6 to 28.6) and require hospital admission (OR=2.8, 95% CI 1.3 to 6.1), powered scooter injuries were nearly three times more likely to result in a diagnosis of concussion (3% of scooter injuries vs 0.5% of E-bike injuries). E-bike-related injuries were also more than three times more likely to involve a collision with a pedestrian than either pedal bicycles (OR=3.3, 95% CI 0.5 to 23.6) or powered scooters (OR=3.3, 95% CI 0.3 to 32.9), but there was no evidence that powered scooters were more likely than bicycles to be involved in a collision with a pedestrian (OR=1.0, 95% CI 0.3 to 3.1). While population-based rates of pedal bicycle-related injuries have been decreasing, particularly among children, reported E-bike injuries have been increasing dramatically particularly among older persons. CONCLUSIONS:E-bike and powered scooter use and injury patterns differ from more traditional pedal operated bicycles. Efforts to address injury prevention and control are warranted, and further studies examining demographics and hospital resource utilisation are necessary.

Traditionally, executive function (EF) tasks have been scored using either accuracy or reaction time (RT) metrics. The current study, which includes 1,015 first-grade children from the Family Life Project, demonstrates a new scoring approach for the Hearts and Flowers (HF) task that uses both item-level accuracy and RT data to estimate latent EF ability. Our primary aim was to compare scores derived from this approach to standard scores often reported in the HF literature. A second aim was to test whether item-level accuracy and RT data were differentially related to latent EF ability, depending on children's overall level of task performance. Our results indicated that item-level accuracy and RT data both convey unique information related to latent EF ability but that the relative contributions of each source of data vary across children. Accuracy was comparatively more informative of latent ability in children with lower HF task performance, while RT was comparatively more informative of latent ability in children with higher overall performance. Moreover, item-level RT was differentially related to latent EF ability for children in lower versus higher performing groups. Whereas faster responding was associated with higher ability in the higher performing group, slower responding was associated with higher ability for the lower performing group. Latent EF ability was related to criterion measures in ways comparable to traditional scores. Results are discussed in relation to the broader EF assessment literature.

Despite widespread interest in the construct of executive functioning (EF), we currently lack definitive evidence regarding the best measurement model for representing the construct in substantive analyses. The most common practice is to represent EF ability as a reflective latent variable, with child performance on individual EF tasks as observed indicators. The current article critically evaluates the dominant use of reflective latent variable models in the child EF literature and compares them to composite models, a reasonable alternative. We review the literature suggesting that reflective latent variable models may not be the most appropriate representation of the construct of EF. Using preschool (M_age = 48.3 months) and first grade (M_age = 83.5 months) data from the Family Life Project (N = 920), we also investigate the implications of measurement model specification for the interpretation of study findings. Children in this sample varied in terms of sex (49% male), race (43% black) and socioeconomic status (76% low-income). Our findings show that the conclusions we draw from 2 substantive analyses differ depending on whether EF is modeled as a reflective latent variable versus a composite variable. We describe the implications of these findings for research on child EF and offer practical recommendations for producers and consumers of developmental research.

Environmental adversity increases child susceptibility to disrupted developmental outcomes, but the mechanisms by which adversity can shape development remain unclear. A translational cross-species approach was used to examine stress-mediated pathways by which poverty-related adversity can influence infant social development. Findings from a longitudinal sample of low-income mother-infant dyads indicated that infant cortisol (CORT) on its own did not mediate relations between early-life scarcity-adversity exposure and later infant behavior in a mother-child interaction task. However, maternal CORT through infant CORT served as a mediating pathway, even when controlling for parenting behavior. Findings using a rodent "scarcity-adversity" model indicated that pharmacologically blocking pup corticosterone (CORT, rodent equivalent to cortisol) in the presence of a stressed mother causally prevented social transmission of scarcity-adversity effects on pup social behavior. Furthermore, pharmacologically increasing pup CORT without the mother present was not sufficient to disrupt pup social behavior. Integration of our cross-species results suggests that elevated infant CORT may be necessary, but without elevated caregiver CORT, may not be sufficient in mediating the effects of environmental adversity on development. These findings underscore the importance of considering infant stress physiology in relation to the broader social context, including caregiver stress physiology, in research and interventional efforts.

Although pediatricians routinely counsel parents about preventing childhood injuries, we know little about parents' locus of control (LOC) in regards to preventing their children from being injured. We performed an observational analysis of sociodemographic differences in LOC for injury prevention, as measured by four items adapted from the Parental Health Beliefs Scales, in English- and Spanish-speaking parents of infants participating in the treatment arm of an obesity prevention study. First, we examined associations of parental LOC for injury prevention at the time their children were 2 months old with parents' age, race/ethnicity, income, and education. Next, we analyzed time trends for repeated LOC measures when the children were 2, 6, 9, 12, and 24 months old. Last, we examined the association between injury-related LOC items and children's injury (yes/no) at each time point. Of 452 parents, those with lower incomes had both lower internal and higher external LOC. Lower educational achievement was associated with higher external LOC. Both internal and external LOC scores decreased over time. Injuries were more common in children whose parents endorsed low internal and high external LOC. Future studies should examine whether primary care-based interventions can increase parents' sense of control over their children's safety and whether that, in turn, is associated with lower injury rates.Clinical Trial Registration: NCT01040897.

Emerging global health challenges and ever-growing health disparities indicate a need to improve the manner by which we deliver health prevention and health care services to people and the populations in which they are nested. One means of addressing the physical, psychological, and social health of people is to more fully and intelligently integrate the social and structural deterministic perspectives of health inherent in public health efforts with the individualistic and behavioral focus of medicine. This integration of public health with clinical care is predicated on the notion that people are burdened by socially produced psychological states that undermine their health. To date, neither public health nor clinical care has effectively attended to psychosocial conditions such as fear, loneliness, medical mistrust, powerlessness, and stigma, all of which fuel disease. Psychological principles provide the means of coalescing the efforts of public health with clinical care by addressing these very psychosocial stressors that undermine health and perpetuate disease. In this regard, there is a need to reorient the discipline of public health psychology. Such a conceptualization of health and well-being provides a framework to both identify and intervene on these conditions. Public health psychologists should collaborate directly with both public health experts and clinical providers to develop tools which effectively ameliorate the psychosocial drivers of disease.
