A Statewide Evaluation of the Implementation of Evidence-Based Suicide Prevention Guidelines in Juvenile Detention Centers.

This study aimed to explore suicide prevention in juvenile detention centers by conducting a case study of one state. Qualitative data from semistructured interviews were synthesized from 10 juvenile detention centers. Analytical techniques included thematic and content analysis and the integration of quantitative information and qualitative themes to illustrate key differences in suicide prevention practices and center characteristics among facilities with varying frequencies of crisis stabilization calls and critical incidents. Although the use of many suicide prevention practices was reported across the sample, the quality with which those practices were implemented was highly variable. The analysis suggests that facilities with higher-quality implementation of suicide prevention practices may have had leaders who acknowledged that their facility plays a role in suicide prevention. Moreover, preliminary evidence suggests that the quality of suicide prevention implementation may be associated with the number of crisis stabilization calls and critical incidents (i.e., variables related to suicidality) a facility experiences. Clear conceptualization of a juvenile detention center's role in suicide prevention may lead to better outcomes in suicide prevention implementation. High-quality implementation may reduce suicidality exhibited by youths in juvenile detention and save lives.

Examining the clinical impact of rapid multiplex polymerase chain reaction-based diagnostic testing for bloodstream infections in a national cohort of the Veterans Health Administration.

STUDY OBJECTIVE: Bloodstream infections (BSIs) are a significant cause of mortality. Use of a rapid multiplex polymerase chain reaction-based blood culture identification panel (BCID) may improve antimicrobial utilization and clinical outcomes by shortening the time to appropriate therapy and de-escalating antibiotics among patients on overly broad-spectrum empiric therapy. The effect of BCID on clinical outcomes across varying institutional antimicrobial stewardship program (ASP) practices is unclear. This study evaluated clinical outcomes associated with the "real-world" implementation of BCID in a national health system with varying ASP practices. DESIGN: National, multicenter, retrospective, pre-post quasi-experimental study of hospitalized patients admitted from 2015 to 2020 to VHA facilities, which introduced the BCID for ≥1 year. SETTING: United States Veterans Health Administration (VHA) hospitals with BCID. PATIENTS: Hospitalized VHA patients with ≥1 blood culture positive for bacteria featured on the BCID panel. INTERVENTION: Comparison of outcomes between the pre- and post-BCID implementation groups. MEASUREMENTS: Outcomes evaluated included early antimicrobial de-escalation within 48 h, defined as reduction in antimicrobial spectrum scores, time to appropriate therapy, and 30-day mortality. MAIN RESULTS: A total of 4138 patients (pre-BCID, n = 2100; post-BCID, n = 2038) met the study criteria. Implementation of BCID was associated with significant improvements in early antimicrobial de-escalation (34.6%: pre-BCID vs. 38.1%: post-BCID; p = 0.022), which persisted after adjusting for other covariates (adjusted risk ratio [aRR], 1.11; 95% confidence interval [CI], 1.02-1.20; p = 0.011). Median time to appropriate therapy was shorter in the post-BCID implementation group relative to the pre-BCID group (9 h: pre-BCID vs. 8 h: post-BCID, respectively, p = 0.005), and a greater percentage of patients received early appropriate antimicrobial therapy within 48 h in the post-BCID implementation group (91.7%: pre-BCID vs. 93.8%: post-BCID; p = 0.008). In the multivariable regression analysis, BCID implementation was significantly associated with a higher likelihood of appropriate therapy within 48 h (aRR, 1.02; 95% CI, 1.01-1.08; p = 0.020). There was no difference in 30-day mortality between groups overall (12.6% pre-BCID vs. 11.2% post-BCID; p = 0.211). CONCLUSIONS: In a "real-world" clinical setting, the implementation of BCID was associated with clinical improvements in antimicrobial utilization. The BCID platform may serve as a useful adjunct for BSI management in facilities with ASP.

Comparison of A1c Reduction, Weight Loss, and Changes in Insulin Requirements With Addition of GLP-1 Agonists vs SGLT-2 Inhibitors in Patients Using Multiple Daily Insulin Injections.

Objective: To determine whether Glucagon-Like Peptide 1 (GLP-1) agonists or Sodium Glucose Transporter 2 (SGLT-2) inhibitors result in greater A1c reduction, weight loss, and reduction of insulin requirements in veterans using multiple daily doses of insulin. Methods: This retrospective, single-site, cohort study included patients of VA Eastern Kansas Health Care System with a diagnosis of Type II Diabetes utilizing multiple daily dose insulin and an SGLT-2 inhibitor or GLP-1 agonist. SAS Enterprise Guide was utilized to complete a multivariate analysis of variance to evaluate all outcomes. Key Findings: 150 patients met selection criteria. The GLP-1 group averaged a .65% reduction in A1c compared to a 1.05% reduction in the SGLT-2 group (P = .1397). The Basal insulin dose was reduced by 5.5 units in the GLP-1 group vs 2.45 units in the SGLT-2 group (P = .3132), and 7.12 units vs 8.14 units respectively for short-acting insulin (P = .8170). The resulting weight reduction was 4.1 Kg in the GLP-1 group compared to 3.6 Kg in the SGLT-2 group (P = .6993). Conclusion: The results suggest there is not a statistically significant difference in changes to A1c, insulin requirements, or weight after 1 year of treatment with an SGLT-2 vs GLP-1 in patients using multiple daily insulin injections.

Impact of Implementation of the Core Elements of Outpatient Antibiotic Stewardship Within Veterans Health Administration Emergency Departments and Primary Care Clinics on Antibiotic Prescribing and Patient Outcomes.

BACKGROUND: The Core Elements of Outpatient Antibiotic Stewardship provide a framework to improve antibiotic use. We report the impact of core elements implementation within Veterans Health Administration sites. METHODS: In this quasiexperimental controlled study, effects of an intervention targeting antibiotic prescription for uncomplicated acute respiratory tract infections (ARIs) were assessed. Outcomes included per-visit antibiotic prescribing, treatment appropriateness, ARI revisits, hospitalization, and ARI diagnostic changes over a 3-year pre-implementation period and 1-year post-implementation period. Logistic regression adjusted for covariates (odds ratio [OR], 95% confidence interval [CI]) and a difference-in-differences analysis compared outcomes between intervention and control sites. RESULTS: From 2014-2019, there were 16 712 and 51 275 patient visits within 10 intervention and 40 control sites, respectively. Antibiotic prescribing rates pre- and post-implementation within intervention sites were 59.7% and 41.5%, compared to 73.5% and 67.2% within control sites, respectively (difference-in-differences, P < .001). Intervention site pre- and post-implementation OR to receive appropriate therapy increased (OR, 1.67; 95% CI, 1.31-2.14), which remained unchanged within control sites (OR,1.04; 95% CI, .91-1.19). ARI-related return visits post-implementation (-1.3% vs -2.0%; difference-in-differences P = .76) were not different, but all-cause hospitalization was lower within intervention sites (-0.5% vs -0.2%; difference-in-differences P = .02). The OR to diagnose non-specific ARI compared with non-ARI diagnoses increased post-implementation forintervention (OR, 1.27; 95% CI, 1.21 -1.34) but not control (OR, 0.97; 95% CI, .94-1.01) sites. CONCLUSIONS: Implementation of the core elements was associated with reduced antibiotic prescribing for RIs and a reduction in hospitalizations. Diagnostic coding changes were observed.

Hippocampal Subgranular Zone FosB Expression Is Critical for Neurogenesis and Learning.

Neural proliferation in the dentate gyrus (DG) is closely linked with learning and memory, but the transcriptional programming that drives adult proliferation remains incompletely understood. Our lab previously elucidated the critical role of the transcription factor ΔFosB in the dorsal hippocampus (dHPC) in learning and memory, and the FosB gene has been suggested to play a role in neuronal proliferation. However, the subregion-specific and potentially cell-autonomous role of dHPC ΔFosB in neurogenesis-dependent learning has not been studied. Here, we crossed neurotensin receptor-2 (NtsR2) Cre mice, which express Cre within the subgranular zone (SGZ) of dHPC DG, with floxed FosB mice to show that knockout of ΔFosB in hippocampal SGZ neurons reduces antidepressant-induced neurogenesis and impedes hippocampus-dependent learning in the novel object recognition task. Taken together, these data indicate that FosB gene expression in SGZ is necessary for both hippocampal neurogenesis and memory formation.

Dipeptidyl Peptidase-4 Inhibitors and Heart Failure Exacerbation in the Veteran Population: An Observational Study.

OBJECTIVES: The dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) are effective modulators of fasting and postprandial hyperglycemia in patients with type 2 diabetes mellitus (T2DM). In 2013 the Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus-Thrombolysis in Myocardial Infarction 53 (SAVOR-TIMI 53) clinical trial found an increased risk of heart failure exacerbation, as a secondary outcome, among patients treated with saxagliptin. This study examines the safety of DPP-4 inhibitors as a class in T2DM in relation to risk of heart failure exacerbations. METHODS: Retrospective cohort study of two groups of patients using data from the national Department of Veteran's Affairs (VA) Health Care System: patients initially prescribed DPP-4 inhibitors with or without second-generation sulfonylureas and/or metformin (exposed group) compared with patients initially prescribed only second-generation sulfonylureas and/or metformin (unexposed group) between August 1, 2013, and August 30, 2016. The primary aim of this study was to determine the difference in 1-year heart failure exacerbation rate in patients with T2DM between the exposed and unexposed groups. Data were analyzed using the χ2 Student t test and Kaplan-Meier analysis. Significance was set at p<0.05. RESULTS: The study evaluated 672,265 patients: 33,614 patients in the exposed group and 638,651 patients in the unexposed group. Overall, 130 (0.38%) heart failure exacerbations were documented in the exposed group, and 2222 (0.34%) heart failure exacerbations were documented in the unexposed group; the difference in exacerbation rate was nonsignificant between groups (p=0.24). In a subgroup analysis of patients with a baseline diagnosis of heart failure, the difference in rate of heart failure exacerbations remained nonsignificant (p=0.334). CONCLUSIONS: Patients in the veteran population with T2DM treated with DPP-4 inhibitors did not demonstrate a significant increase in risk for heart failure exacerbation, regardless of whether a patient had been previously diagnosed with heart failure. This finding potentially supports safe usage of DPP-4 inhibitors in this patient population regardless of heart failure diagnosis.

Effect of Continuous and Sequential Therapy among Veterans Receiving Daptomycin or Linezolid for Vancomycin-Resistant Enterococcus faecium Bacteremia.

Vancomycin-resistant Enterococcus faecium bloodstream infections (VREF-BSI) cause significant mortality, highlighting the need to optimize their treatment. We compared the effectiveness and safety of daptomycin (DAP) and linezolid (LZD) as continuous or sequential therapy for VREF-BSI in a national, retrospective, propensity score (PS)-matched cohort study of hospitalized Veterans Affairs patients (2004 to 2014). We compared clinical outcomes and adverse events among patients treated with continuous LZD, continuous DAP, or sequential LZD followed by DAP (LZD-to-DAP). Secondarily, we analyzed the impact of infectious diseases (ID) consultation and source of VREF-BSI. A total of 2,630 patients were included in the effectiveness analysis (LZD [n = 1,348], DAP [n = 1,055], LZD-to-DAP [n = 227]). LZD was associated with increased 30-day mortality versus DAP (risk ratio [RR], 1.11; 95% confidence interval [CI], 1.01 to 1.22; P = 0.042). After PS matching, this relationship persisted (RR, 1.13; 95% CI, 1.02 to 1.26; P = 0.015). LZD-to-DAP switchers had lower mortality than those remaining on LZD (RR, 1.29; 95% CI, 1.03 to 1.63; P = 0.021), suggesting a benefit may still be derived with sequential therapy. LZD-treated patients experienced more adverse events, including a ≥50% reduction in platelets (RR, 1.07; 95% CI, 1.03 to 1.11; P = 0.001). DAP was associated with lower mortality than was LZD in patients with endocarditis (RR, 1.20; 95% CI, 1.02 to 1.41; P = 0.024); however, there was no statistically significant association between treatment group and mortality with regard to other sources of infection. Therefore, source of infection appears to be important in selection of patients most likely to benefit from DAP over LZD.
