    Abstract Native Hawaiians have a disproportionately high prevalence of hypertension, which is an important and modifiable risk factor for cardiovascular disease (CVD). To reduce CVD among Native Hawaiians, we must better understand facilitators and barriers to hypertension management (i.e., diet, physical activity, stress reduction) unique to Native Hawaiians. Despite evidence of neighborhood-level facilitators and barriers to hypertension management in other populations, there is limited research in Native Hawaiians.

    Abstract Native Hawaiians have a disproportionately high prevalence of hypertension, which is an important and modifiable risk factor for cardiovascular disease (CVD). To reduce CVD among Native Hawaiians, we must better understand facilitators and barriers to hypertension management (i.e., diet, physical activity, stress reduction) unique to Native Hawaiians. Despite evidence of neighborhood-level facilitators and barriers to hypertension management in other populations, there is limited research in Native Hawaiians. Participants from a randomized controlled trial (n = 40) were recruited for 5 focus groups. All participants were self-reported Native Hawaiians and had uncontrolled hypertension. Discussions elicited experiences and perceptions of neighborhood-level stressors as they relate to participants’ hypertension management efforts. Audio recordings were transcribed and analyzed using ATLAS.ti for emergent themes. Five themes were identified: neighborhood description, community resources, neighborhood change, safety, and social connectedness. Novel barriers to hypertension control included loss of culture and loss of respect for elders, change in community feel, and over-development. Facilitators included social cohesion and collective power. These data provide a deeper understanding of how Native Hawaiians experience neighborhood factors and how those factors impact their efforts to improve their diets, physical activity, and stress management. The findings help to inform the development of multilevel CVD prevention programs. Further research is needed to explore the subtheme of social and emotional stress related to neighborhood change and CVD health risk due to cultural and historic trauma references.

    Abstract Background: Invasive bacterial infections (IBIs) in febrile infants are rare but potentially devastating. We aimed to derive and validate a predictive model for IBI among febrile infants age 7-60 days.
    Methods: Data were abstracted retrospectively from electronic records of 37 emergency departments (EDs) for infants with a measured temperature >=100.4 F who underwent an ED evaluation with blood and urine cultures. Models to predict IBI were developed and validated respectively using a random 80/20 dataset split, including 10-fold cross-validation. We used precision recall curves as the classification metric.
    Results: Of 4411 eligible infants with a mean age of 37 days, 29% had characteristics that would likely have excluded them from existing risk stratification protocols. There were 196 patients with IBI (4.4%), including 43 (1.0%) with bacterial meningitis. Analytic approaches varied in performance characteristics (precision recall range 0.04-0.29, area under the curve range 0.5-0.84), with the XGBoost model demonstrating the best performance (0.29, 0.84). The five most important variables were serum white blood count, maximum temperature, absolute neutrophil count, absolute band count, and age in days.
    Conclusion: A machine learning model (XGBoost) demonstrated the best performance in predicting a rare outcome among febrile infants, including those excluded from existing algorithms.
    Impact: Several models for the risk stratification of febrile infants have been developed. There is a need for a preferred comprehensive model free from limitations and algorithm exclusions that accurately predicts IBIs. This is the first study to derive an all-inclusive predictive model for febrile infants aged 7-60 days in a community ED sample with IBI as a primary outcome. This machine learning model demonstrates potential for clinical utility in predicting IBI.

    Abstract Background: Limited data exist to guide blood culture ordering in persistent febrile neutropenia (FN), resulting in substantial variation in practice. Unnecessary repeat blood cultures have been associated with patient harm including increased antimicrobial exposure, hospital length of stay, catheter removal, and overall cost.
    Methods: We conducted a single-center study of adult hematology-oncology patients with ≥3 days of FN. The yield of blood cultures was first evaluated in a 2-year historical cohort. Additionally, a pilot pre-/postintervention study was performed in non-stem cell transplant (SCT) patients following a change in our population clinical practice guideline from a recommendation of daily blood cultures to a clinically guided approach. The primary outcome was cultures collected per days of FN after day 3 of persistent FN.
    Results: One hundred forty-six episodes of ≥3 days of FN in 108 patients were identified during the historical period. Day 1 blood cultures were positive in 23 of 146 (16%) episodes. Blood cultures were drawn on 374 of 513 (73%) subsequent episode-days (day 2-12) and were negative in 366 of 374 (98%). After the intervention, a 53% decrease was observed in the rate of total blood cultures collected (1.4 preintervention vs 0.7 postintervention;
    Conclusions: Repeat blood cultures are low-yield in persistent FN without new clinical change. A pilot intervention in non-SCT patients successfully reduced the frequency of blood culture collection.

    Abstract Cognitive dysfunction in aging is a major biomedical challenge. Whether treatment with klotho, a longevity factor, could enhance cognition in human-relevant models such as in nonhuman primates is unknown and represents a major knowledge gap in the path to therapeutics. We validated the rhesus form of the klotho protein in mice showing it increased synaptic plasticity and cognition. We then found that a single administration of low-dose, but not high-dose, klotho enhanced memory in aged nonhuman primates. Systemic low-dose klotho treatment may prove therapeutic in aging humans.

    Abstract In July 2021, the Virginia Department of Health notified CDC of a cluster of eight invasive infections with Burkholderia stabilis, a bacterium in the Burkholderia cepacia complex (BCC), among hospitalized patients at hospital A. Most patients had undergone ultrasound-guided procedures during their admission. Culture of MediChoice M500812 nonsterile ultrasound gel used in hospital A revealed contamination of unopened product with B. stabilis that matched the whole genome sequencing (WGS) of B. stabilis strains found among patients. CDC and hospital A, in collaboration with partner health care facilities, state and local health departments, and the Food and Drug Administration (FDA), identified 119 B. stabilis infections in 10 U.S. states, leading to the national recall of all ultrasound gel products produced by Eco-Med Pharmaceutical (Eco-Med), the manufacturer of MediChoice M500812. Additional investigation of health care facility practices revealed frequent use of nonsterile ultrasound gel to assist with visualization in preparation for or during invasive, percutaneous procedures (e.g., intravenous catheter insertion). This practice could have allowed introduction of contaminated ultrasound gel into sterile body sites when gel and associated viable bacteria were not completely removed from skin, leading to invasive infections. This outbreak highlights the importance of appropriate use of ultrasound gel within health care settings to help prevent patient infections, including the use of only sterile, single-use ultrasound gel for ultrasonography when subsequent percutaneous procedures might be performed.

    Abstract Astrocytes are one of the most numerous glial cells in the central nervous system (CNS) and provide essential support to neurons to ensure CNS health and function. During a neuropathological challenge, such as during human immunodeficiency virus (HIV)-1 infection or (METH)amphetamine exposure, astrocytes shift their neuroprotective functions and can become neurotoxic. Identifying cellular and molecular mechanisms underlying astrocyte dysfunction are of heightened importance to optimize the coupling between astrocytes and neurons and ensure neuronal fitness against CNS pathology, including HIV-1-associated neurocognitive disorders (HAND) and METH use disorder. Mitochondria are essential organelles for regulating metabolic, antioxidant, and inflammatory profiles. Moreover, endoplasmic reticulum (ER)-associated signaling pathways, such as calcium and the unfolded protein response (UPR), are important messengers for cellular fate and function, including inflammation and mitochondrial homeostasis. Increasing evidence supports that the three arms of the UPR are involved in the direct contact and communication between ER and mitochondria through mitochondria-associated ER membranes (MAMs). The current study investigated the effects of HIV-1 infection and chronic METH exposure on astrocyte ER and mitochondrial homeostasis and then examined the three UPR messengers as potential regulators of astrocyte mitochondrial dysfunction. Using primary human astrocytes infected with pseudotyped HIV-1 or exposed to low doses of METH for 7 days, astrocytes had increased mitochondrial oxygen consumption rate (OCR), cytosolic calcium flux and protein expression of UPR mediators. Notably, inositol-requiring protein 1α (IRE1α) was most prominently upregulated following both HIV-1 infection and chronic METH exposure. Moreover, pharmacological inhibition of the three UPR arms highlighted IRE1α as a key regulator of astrocyte metabolic function. To further explore the regulatory role of astrocyte IRE1α, astrocytes were transfected with an IRE1α overexpression vector followed by activation with the proinflammatory cytokine interleukin 1β. Overall, our findings confirm IRE1α modulates astrocyte mitochondrial respiration, glycolytic function, morphological activation, inflammation, and glutamate uptake, highlighting a novel potential target for regulating astrocyte dysfunction. Finally, these findings suggest both canonical and non-canonical UPR mechanisms of astrocyte IRE1α. Thus, additional studies are needed to determine how to best balance astrocyte IRE1α functions to both promote astrocyte neuroprotective properties while preventing neurotoxic properties during CNS pathologies.

    Abstract Piperacillin-tazobactam (TZP) is frequently used for intra-abdominal infection (IAI). Our institution experienced consecutive shortages of TZP and cefepime, providing an opportunity to review prescribing patterns and microbiology for IAI. Hospitalized adult patients treated for IAI, based on provider selection of IAI as the indication within the antibiotic order, between March 2014 and February 2018 were identified from the University of Virginia Clinical Data Repository and Infection Prevention and Control Database. Antimicrobial utilization, microbiologic data, and clinical outcomes were compared across four year-long periods: pre-shortage, TZP shortage, cefepime shortage, and post-shortage. There were 7,668 episodes of antimicrobial prescribing for an indication of IAI during the study period. Cefepime use for IAI increased 190% during the TZP shortage; meanwhile ceftriaxone use increased by only 57%. There was no increase in in-house mortality, colonization with resistant organisms, or
