Subjective cognitive decline (SCD) is associated with preclinical Alzheimer's disease (AD). Suboptimal sleep is also a risk factor for cognitive decline, but with unclear relationship to SCD. We conducted a retrospective cross-sectional study in a biracial research cohort of 148 cognitively normal older adults who underwent quantification of SCD (Cognitive Change Index; CCI), sleepiness (Epworth Sleepiness Scale; ESS), depression (Geriatric Depression Scale; GDS), and amyloid/tau PET. ESS score was associated with total, amnestic, and non-amnestic CCI scores, after adjustment for GDS, amyloid/tau burden, and race. This supports future longitudinal work on how sleepiness impacts SCD outcomes.

AIM/OBJECTIVE:This integrative review examines the impact of team teaching in undergraduate and master's degree nursing programs. BACKGROUND:Increasing workloads for faculty are a challenge in nursing education. Team teaching allows shared responsibilities; work between two or more educators can help redistribute workloads and mitigate burnout. METHOD/METHODS:A systematic search of peer-reviewed articles in Cumulative Index to Nursing and Allied Health Literature, Education Resource Information Center, and PubMed yielded 12 relevant studies. RESULTS:Four key themes emerged: modeling behaviors, applying theoretical knowledge to practice, exposure to diverse perspectives, and faculty perspectives. Effective team teaching requires trust, communication, and collaboration among educators, requiring ongoing professional development. Team teaching can enhance diversity efforts in nursing education. CONCLUSION/CONCLUSIONS:Team teaching is a viable approach to optimizing the scholarship of teaching. Future research should explore educators' perspectives on team-teaching methods and measurable impacts on achieving learning outcomes.

BACKGROUND AND OBJECTIVE/OBJECTIVE:The diagnosis of interstitial lung diseases (ILDs) often relies on the integration of various clinical, radiological, and histopathological data. Achieving high diagnostic accuracy in ILDs, particularly for distinguishing usual interstitial pneumonia (UIP), is challenging and requires a multidisciplinary approach. Therefore, this study aimed to develop a multimodal artificial intelligence (AI) algorithm that combines computed tomography (CT) and histopathological images to improve the accuracy and consistency of UIP diagnosis. METHODS:A dataset of CT and pathological images from 324 patients with ILD between 2009 and 2021 was collected. The CT component of the model was trained to identify 28 different radiological features. The pathological counterpart was developed in our previous study. A total of 114 samples were selected and used for testing the multimodal AI model. The performance of the multimodal AI was assessed through comparisons with expert pathologists and general pathologists. RESULTS:The developed multimodal AI demonstrated a substantial improvement in distinguishing UIP from non-UIP, achieving an AUC of 0.92. When applied by general pathologists, the diagnostic agreement rate improved significantly, with a post-model κ score of 0.737 compared to 0.273 pre-model integration. Additionally, the diagnostic consensus rate with expert pulmonary pathologists increased from κ scores of 0.278-0.53 to 0.474-0.602 post-model integration. The model also increased diagnostic confidence among general pathologists. CONCLUSION/CONCLUSIONS:Combining CT and histopathological images, the multimodal AI algorithm enhances pathologists' diagnostic accuracy, consistency, and confidence in identifying UIP, even in cases where specialised expertise is limited.

BACKGROUND:Patients undergoing invasive mechanical ventilation often require pharmacologic sedation to facilitate tolerance of this life-sustaining intervention, but sedatives currently used in routine care have substantial limitations. Isoflurane is an inhaled volatile anesthetic with pharmacologic properties potentially suitable to sedation of ventilator-dependent critically ill patients, but need for specialized drug administration equipment has limited its use historically to general anesthesia in the operating theatre. This trial will evaluate isoflurane, administered using a novel drug delivery system, for sedation of ventilator-dependent adult intensive care unit (ICU) patients in the United States (US). METHODS:The Inhaled Sedation versus Propofol in Respiratory Failure in the ICU (INSPiRE-ICU2) is a phase 3, multicenter, randomized, controlled, assessor-blinded non-inferiority trial that will evaluate efficacy and safety of inhaled isoflurane delivered via the Sedaconda ACD-S, compared to intravenous propofol, for sedation of mechanically ventilated adult ICU patients. At 16 US hospitals, 235 enrolled patients requiring continuous sedation during invasive mechanical ventilation will be randomized in 1.5:1 ratio to inhaled isoflurane or intravenous propofol for sedation. Treatment duration is expected to be at least 12 h and may last up to 48 (± 6) h or until no longer needing continuous sedation, whichever occurs first. The primary endpoint is the percentage of time sedation depth is maintained within the targeted range (Richmond Agitation Sedation Scale - 1 to - 4), in the absence of rescue sedation, during the treatment period. Secondary superiority outcomes include opioid exposure, wake-up time, cognitive recovery after end-of-treatment, and preservation of spontaneous breathing effort. DISCUSSION/CONCLUSIONS:The INSPiRE-ICU2 trial will help determine the potential role of isoflurane for sedation of ventilator-dependent adult patients in the ICU. Key trial design features, including adoption of the estimand framework and blinded assessments of sedation depth, pain, and cognitive recovery, will ensure a rigorous evaluation of isoflurane for ICU sedation.

BACKGROUND/UNASSIGNED:In May 2022, mpox (formerly monkeypox) began spreading globally through LGBTQ+ sexual networks. By August 2022, New York City (NYC) became the global epicenter of the mpox outbreak, with the highest number of cases reported in the United States. Here, we quantify the mpox vaccination effort, focusing on flexible and community-responsive mobile vaccination. METHODS/UNASSIGNED:We describe an on-site mpox vaccination strategy at commercial sex venues, nightlife venues, and pride and health centers, during August 1-November 15, 2022. Data were collected on doses, demographics, and event size to determine and evaluate vaccine uptake. RESULTS/UNASSIGNED:The on-site vaccination strategy resulted in 3358 JYNNEOS doses administered at 363 events at 58 locations, including 22 events at 2 commercial sex venues. Commercial sex venues in New York City closed at the height of the mpox epidemic. We show high uptake of the JYNNEOS vaccine at commercial sex venues, with as many as 60% of attendees of 1 event receiving a JYNNEOS vaccine dose on site. This was possible after New York City health agencies responded to community demand for second doses. Messaging about the importance and availability of vaccination at these parties was community-led. JYNNEOS vaccination via mobile clinics demonstrated less racial and geographic disparity compared with nonmobile vaccinations. We show no increase in mpox cases as commercial sex venues reopened with vaccination on site. CONCLUSIONS/UNASSIGNED:These results demonstrate the success of a community-led rapid response to an emergent mpox outbreak, including at places where people meet for sex.

BACKGROUND:Drug overdose deaths have increased fivefold over the last 20 years, primarily fueled by synthetic opioids, which led the Centers for Disease Control and Prevention to declare an opioid overdose epidemic. Responding to this epidemic, we designed and implemented opioid overdose prevention (OOP) training for medical students to help promote effective naloxone usage. Previously, we compared online and in-person versions of OOP training over 2 years of training. To better establish the evidence for online training, we performed a randomized controlled non-inferiority trial comparing in-person with online opioid prevention training. METHODS:Third-year medical students were randomized into groups to receive either in-person or online training in preparation for clinical rotations. Students randomized to receive online training were provided a link to the training modules. Students randomized to receive in-person training were trained in an in-person setting. We performed a non-inferiority per-protocol analysis with the primary outcome of knowledge using a non-inferiority margin of a -9.1% difference between groups. RESULTS:A total of 205 students were randomized, 103 students to in-person training and 102 to online training. Eighty-three in-person students and 104 online students were included. The online group had a higher post-training knowledge score compared to the in-person group by 0.44 points (0-11 point scale) with a 95% CI of (-0.04, 0.93) that did not cross the margin of non-inferiority. CONCLUSIONS:Online training for OOP was effective and non-inferior to in-person training. Online OOP training may be considered an alternative to in-person training.

Rheumatoid arthritis is a common chronic inflammatory arthritis, primarily characterized by proliferative synovitis of the small joints of the appendicular skeleton. Rapidly evolving treatment regimens for rheumatoid arthritis patients, including conventional and biologic disease-modifying antirheumatic drugs, promise improved quality of life and prognosis. These treatments necessitate earlier clinical detection of rheumatoid arthritis, a goal that has forever changed the role of imaging in this pursuit. This review discusses the dominant imaging modalities in state-of-the-art rheumatoid arthritis management: radiography, magnetic resonance imaging, and ultrasound. It focuses on hand and wrist evaluation, with key relevant findings detected by each modality and recent evidence supporting them. Emerging techniques are also described in this discussion to understand likely future radiologic contributions to rheumatoid arthritis diagnosis and management.

BACKGROUND/OBJECTIVES/UNASSIGNED:Myocardial and liver iron overload can be assessed through T2* in magnetic resonance imaging (MRI). It is unclear, how T2* measurements are associated with systolic and diastolic left ventricular function assessed by novel feature tracking (FT) strain. METHODS/UNASSIGNED:Consecutive patients with suspected iron overload undergoing MRI T2* were retrospectively included. T2* was studied continuously and in categories: normal myocardial iron status (T2* ≥ 20 ms), myocardial iron overload (T2* < 20 ms), normal liver iron status (T2* ≥ 15.4 ms) and liver iron overload (T2* < 15.4 ms). Multivariable regression models were used to assess associations between T2* and FT strain. RESULTS/UNASSIGNED: = 0.008]. No associations of T2* values with systolic function were found. CONCLUSION/UNASSIGNED:Liver and a combination of myocardial and liver iron overload were associated with increased early diastolic filling and increased e/a ratio respectively, which may serve as markers of diastolic dysfunction. Impaired diastolic function, even in the absence of myocardial iron overload was associated with liver iron metabolism and may indicate early cardiac involvement, while left ventricular systolic function is still preserved.
