OBJECTIVES/GOALS: Using the NIH’s expanded definition of underrepresented populations in the biomedical, clinical, behavioral and social science research enterprise, we examined the impediments for conducting translational research experienced by those from underrepresented groups.

The survey addressed barriers to conducting clinical and translational research at the respondent’s institution, awareness of and interest in using specific Advance RI-CTR services, and satisfaction with their institution’s efforts to support clinical and translational research. RESULTS/ANTICIPATED RESULTS: Women reported access to collaboration across institutions as a barrier to clinical and translational research that existed to a great extent (28%) significantly more than men (10%). More than half (53%) of the other underrepresented researchers surveyed identified insufficient grant administration supportas a barrier that occurs to a great extent, compared with 35% of researchers who were not from an underrepresented group. Other barriers reported more frequently among underrepresented researchers included lack of pilot project funding, inadequate space for conducting research, lower access to collaborators across institutions, and difficulty obtaining advice on regulatory issues and commercial development. DISCUSSION/SIGNIFICANCE: Efforts to address the barriers identified by underrepresented groups will include, but not be limited to, improving collaborations across institutions, support for grant administration, and a discussion of plans for the Center to augment and advocate at the partner institutions on behalf of these underrepresented individuals.

The cleavage of two single-crystal chlorites (a clinochlore and a penninite) has been studied using angle-resolved X-ray photoelectron spectroscopy (XPS). Both minerals cleaved in regions not typical of the bulk; the composition of the clinochlore was found to be especially non-uniform. The brucitic interlayer divided evenly between the pair of new surfaces exposed for two cleaves in the clinochlore, but was partitioned unequally in two cleaves in the penninite. The differences in apparent composition between the complementary pairs of surfaces are interpreted to show a marked preference of octahedral Al for the brucitic layer, in agreement with X-ray bulk structure refinements. For both chlorites, the layer charge was reduced in regions of easy cleavage, which also had a higher proportion of Si and less tetrahedral Al than the bulk chlorite. The percentages of tetrahedral aluminium deduced from the XPS surface analyses agreed satisfactorily with the percentages independently determined by consideration of the magnitude of anisotropy in the X-ray photoelectron diffraction (XPD) patterns. The XPD patterns from the clinochlore for rotation about axes parallel and antiparallel to the crystallographic a-axis were identical, showing that tetrahedral ordering was absent.

Background: Statistically significant decreases in methicillin-resistant Staphylococcus aureus (MRSA) healthcare-associated infections (HAIs) occurred in Veterans Health Administration (VA) facilities from 2007 to 2019 using active surveillance for facility admissions and contact precautions for patients colonized (CPC) or infected (CPI) with MRSA, but the value of these interventions is controversial. Objective: To determine the impact of active surveillance, CPC, and CPI on prevention MRSA HAIs, we conducted a prospective cohort study between July 2020 and June 2022 in all 123 acute-care VA medical facilities. In April 2020, all facilities were given the option to suspend any combination of active surveillance, CPC, or CPI to free up laboratory resources for COVID-19 testing and conserve personal protective equipment. We measured MRSA HAIs (cases per 1,000 patient days) in intensive care units (ICUs) and non-ICUs by the infection control policy. Results: During the analysis period, there were 917,591 admissions, 5,225,174 patient days, and 568 MRSA HAIs. Only 20% of facilities continued all 3 MRSA infection control measures in July 2020, but this rate increased to 57% by June 2022. The MRSA HAI rate for all infection sites in non-ICUs was 0.07 (95% CI, 0.05–0.08) for facilities practicing active surveillance plus CPC plus CPI compared to 0.12 (95% CI, 0.08–0.19; P = .01) for those not practicing any of these strategies, and in ICUs the MRSA HAI rates were 0.20 (95% CI, 0.15–0.26) and 0.65 (95% CI, 0.41–0.98; P < .001) for the respective policies. Similar differences were seen when the analyses were restricted to MRSA bloodstream HAIs. Accounting for monthly COVID-19 admissions to facilities over the analysis period using a negative binomial regression model did not change the relationships between facility policy and MRSA HAI rates in the ICUs or non-ICUs. There was no statistically significant difference in monthly facility urinary catheter-associated infection rates, a nonequivalent dependent variable, in the categories during the analysis period in either ICUs or non-ICUs. Conclusions: In Veterans Affairs medical centers, there were fewer MRSA HAIs when facilities practiced active surveillance and contact precautions for colonized or infected patients during the COVID-19 pandemic. The effect was greater in ICUs than non-ICUs.

People with psychosis in Malawi have very limited access to timely assessment and evidence-based care, leading to a long duration of untreated psychosis and persistent disability. Most people with psychosis in the country consult traditional or religious healers. Stigmatising attitudes are common and services have limited capacity, particularly in rural areas. This paper, focusing on pathways to care for psychosis in Malawi, is based on the Wellcome Trust Psychosis Flagship Report on the Landscape of Mental Health Services for Psychosis in Malawi. Its purpose is to inform Psychosis Recovery Orientation in Malawi by Improving Services and Engagement (PROMISE), a longitudinal study that aims to build on existing services to develop sustainable psychosis detection systems and management pathways to promote recovery.

The next generation of high-power lasers enables repetition of experiments at orders of magnitude higher frequency than what was possible using the prior generation. Facilities requiring human intervention between laser repetitions need to adapt in order to keep pace with the new laser technology. A distributed networked control system can enable laboratory-wide automation and feedback control loops. These higher-repetition-rate experiments will create enormous quantities of data. A consistent approach to managing data can increase data accessibility, reduce repetitive data-software development and mitigate poorly organized metadata. An opportunity arises to share knowledge of improvements to control and data infrastructure currently being undertaken. We compare platforms and approaches to state-of-the-art control systems and data management at high-power laser facilities, and we illustrate these topics with case studies from our community.
