Previous cross-sectional studies have documented associations between positive psychosocial factors, such as self-efficacy and emotional support, and late-life cognition. Further, the magnitudes of concurrent associations may differ across racial and ethnic groups that differ in Alzheimer's disease risk. The goals of this longitudinal study were to characterize prospective associations between positive psychosocial factors and cognitive decline and explicitly test for differential impact across race and ethnicity.

578 older adults (42% non-Hispanic Black, 31% non-Hispanic White, and 28% Hispanic) in the Washington Heights-Inwood Columbia Aging Project completed cognitive and psychosocial measures from the NIH Toolbox and standard neuropsychological tests over 2.4 years. Latent difference scores were used to model associations between positive psychosocial factors and cognitive decline controlling for baseline cognition, sociodemographics, depressive symptoms, physical health, and other positive psychosociomote cognitive health in late life.
In the absence of pyuria, positive urine cultures are unlikely to represent infection. Conditional urine reflex culture policies have the potential to limit unnecessary urine culturing. We evaluated the impact of this diagnostic stewardship intervention.

We conducted a retrospective, quasi-experimental (nonrandomized) study, with interrupted time series, from August 2013 to January 2018 to examine rates of urine cultures before versus after the policy intervention. We compared 3 intervention sites to 3 control sites in an aggregated series using segmented negative binomial regression.

The study included 6 acute-care hospitals within the Veterans' Health Administration across the United States.

Adult patients with at least 1 urinalysis ordered during acute-care admission, excluding pregnant patients or those undergoing urological procedures, were included.

At the intervention sites, urine cultures were performed if a preceding urinalysis met prespecified criteria. GDC-0077 ic50 No such restrictions occurred at the control sites. The primary outcome was the rate of urine cultures performed per 1,000 patient days. The safety outcome was the rate of gram-negative bloodstream infection per 1,000 patient days.

The study included 224,573 urine cultures from 50,901 admissions in 24,759 unique patients. Among the intervention sites, the overall average number of urine cultures performed did not significantly decrease relative to the preintervention period (5.9% decrease; P = 0.8) but did decrease by 21% relative to control sites (P < .01). We detected no significant difference in the rates of gram-negative bloodstream infection among intervention or control sites (P = .49).

Conditional urine reflex culture policies were associated with a decrease in urine culturing without a change in the incidence of gram-negative bloodstream infection.

This study extends that line of research to children under the age of four. Thirty-eight monolingual Spanish-speaking children were tested in two PMTs. The results show that at age three children differ from older children in their interpretation of the copulas suggesting that the distinction between ser and estar with adjectives emerges between the ages of three and four.
The Advanced Cardiac Life Support (ACLS) guidelines were recently updated to include ultrasound confirmation of endotracheal tube (ETT) location as an adjunctive tool to verify placement. While this method is employed in the emergency department under the guidance of the most recent American College of Emergency Physicians (ACEP; Irving, Texas USA) guidelines, it has yet to gain wide acceptance in the prehospital setting where it has the potential for greater impact. The objective of this study to is determine if training critical care medics using simulation was a feasible and reliable method to learn this skill.

Twenty critical care paramedics with no previous experience with point-of-care ultrasound volunteered for advanced training in prehospital ultrasound. Four ultrasound fellowship trained emergency physicians proctored two three-hour training sessions. Each session included a brief introduction to ultrasound "knobology," normal sonographic neck and lung anatomy, and how to identify ETT placement wFurther studies on implementation into patient care scenarios are needed.
The use of ultrasound to confirm ETT placement can be effectively taught to critical care medics using a short, simulation-based training session. Further studies on implementation into patient care scenarios are needed.
Cancer is one of the biggest health challenges of our times, affecting all the personal areas of a patient. The interrelationships between these areas and the need for multidisciplinary care require the assessment of psychosocial complexity in cancer patients. The main aim of this study was to reach a consensus on the general definition of psychosocial complexity in cancer and its main elements according to the experts in the field.

A Delphi study was performed, which first involved a comprehensive review of the literature to create a questionnaire that was validated by two expert panels. The first panel consisted of intra-institutional experts, while the second included extra-institutional experts in the field. The study included three more rounds (1) validation of the questionnaire by the internal panel, (2) discussion of the results and resolving discrepancies, and (3) validation of the questionnaire by the external panel.

After the four-round Delphi process, we obtained a consensus definition of psychosocial complexity in cancer patients, as well as of its main factors medical-physical, social-family, psychological, and spiritual.
