Importance The potential utility of real-time digital therapeutics that identify impending behavioral outbursts to proactively apply evidence-based interventions for managing children with disruptive behavior disorder has not been tested. Objectives To evaluate feasibility and adherence of a digitally augmented, real-time, proactive behavioral intervention (smartwatch) for children with disruptive behaviors. Design, Setting, and Participants This randomized clinical trial was conducted between March 1, 2022, and December 31, 2023, at Mayo Clinic in Rochester, Minnesota. The study enrolled children aged 3 to 7 years with externalizing behavior problems rated above the clinically significant range (I score ≥120; T score ≥60) on the Eyberg Child Behavior Inventory (ECBI). Interventions Twelve weekly sessions of parent-child interaction therapy (PCIT) (treatment as usual [TAU] arm) vs artificial intelligence (AI)–enhanced PCIT augmented with real-time behavioral outburst alerts (PCIT-AI arm). Main Outcomes and Measures The primary outcome was achieving the a priori feasibility benchmark set at greater than 70% for both completion of PCIT sessions and daily smartwatch wear. Parental reaction time to behavior prompts was measured in seconds. Secondary outcomes were percentage changes in ECBI and Pediatric Sleep Questionnaire scores. Behavioral outburst duration was examined based on parental logs of start and end times of observed tantrums using a smartphone application. Result This study enrolled 50 children (median [IQR] age, 5.0 [4.0-6.0] years; 34 [68%] male and 16 [32%] female; 28 randomized to the PCIT-AI arm and 22 to the PCIT-TAU arm). Of these children, 37 (74%; 21 in the PCIT-AI arm and 16 in the PCIT-TAU arm) completed PCIT, with children wearing the watch a median (IQR) 75.7% (67.8%-82.9%) of the time, thus achieving the feasibility benchmark (primary outcome). Median (IQR) response time to behavior prompts in the PCIT-AI arm was 3.65 (2.07-7.08) seconds. Assessing between-group differences, there was no statistically significantly greater numerical improvement in ECBI-intensity percentage change (13.86%; 95% CI, −1.41% to 29.14%), ECBI-problem percentage change subscale scores (38.59%; 95% CI, −1.22% to 78.40%), or absolute change in Pediatric Sleep Questionnaire scores (−0.16; 95% CI, −1.85 to 1.53) with the PCIT-AI arm than with the PCIT-TAU arm. Children in the PCIT-AI arm had significantly shorter mean (SD) tantrum durations (10.4 [20.8] minutes vs 22.1 [30.0] minutes; P < .001) and lower odds of tantrums lasting for 15 minutes or more (odds ratio, 3.66; 95% CI, 2.72-4.95). Conclusions and Relevance In this randomized clinical trial, both recruitment and technology feasibility benchmarks were achieved. The findings inform the design of fully powered efficacy study of wearable, digitally augmented PCIT for children with disruptive behaviors.

Background While rapid response teams (RRT) are widely implemented to address clinical deterioration in hospitalized patients, their impact on goals of care (GOC) discussions remains underexplored. Aims We aimed to evaluate whether RRT activations were associated with subsequent goals of care discussions, code status changes, and clinical outcomes. Methods We conducted a retrospective single-center review of hospitalized adult patients admitted to medicine services who had RRT activations between January and December 2023. The primary outcome was GOC discussion within 72 h of RRT. GOC discussions were identified through EMR documentation of conversations, code status changes, and ACP notes. Secondary outcomes included code status change, transition to comfort care, and 30- and 90-day mortality. Analyses were adjusted using inverse probability of treatment weighting. Results 1823 RRTs among 1677 patients were analyzed; 47% of patients were female and 88% identified as white. Those transferred to the ICU had higher odds of goals of care discussions (OR 1.52, P < 0.001), code status change (OR 2.43, P < 0.001), and transition to comfort care (OR 1.47, P = 0.026) compared to those who remained on the floor. ICU transfer was also associated with increased 30- (OR 1.39, P = 0.006) and 90-day mortality (OR 1.30, P = 0.014). Conclusions ICU transfer following RRT activation is strongly associated with downstream goals of care discussions, changes in code status, comfort-focused care, and higher mortality. This demonstrates the importance of initiating goals of care discussions early and often, regardless of whether clinical decompensation is anticipated.

Abstract Objectives To compare the efficacy and safety of antibiotic lock therapy (ALT) versus catheter removal in managing central vascular catheter–associated bloodstream infection (CVC-BSI). Methods We conducted a single-centre, retrospective cohort study of adult patients treated with ALT or catheter removal for management of CVC-BSI between 2018 and 2022. The primary outcome was a composite of 90 day microbiological relapse or recurrent BSI. Secondary outcomes included 30 day mortality, CVC-associated complications and Clostridioides difficile infection (CDI). Logistic regression with propensity score-adjustment was used to evaluate differences in outcomes and identify predictors of relapse. Results During the study period, 106 participants received ALT and 181 underwent catheter removal. Patients treated with ALT received shorter courses of systemic antimicrobials (11 versus 14 days; P &lt; 0.001) and had shorter hospital stays (4 versus 10 days; P &lt; 0.001). Median duration of catheter salvage in patients receiving ALT was 28 days (IQR 7–80). Primary composite outcome was similar between both groups, but ALT was associated with a significantly higher risk of microbiological relapse within 90 days (20% versus 7%; adjusted odds ratio 3.93, 95% CI 1.64–9.40; P = 0.002). No significant difference in 30 day mortality, CVC-related complications or CDI was observed. CoNS BSI was an independent predictor of microbiological relapse in patients treated with ALT (OR 2.28; P = 0.05). Conclusions Although ALT offers a non-invasive catheter salvage strategy, its association with higher relapse rates, particularly in CoNS BSI, suggests catheter removal should remain the preferred approach when feasible. ALT could be considered a short-term catheter salvage strategy for pathogens with low virulence when used with close surveillance.

Abstract Introduction The SleepImage is an HSAT device (sHSAT) that uses photoplethysmography and oxygen saturation data to generate an apnea hypopnea index (AHI). This sHSAT has been FDA cleared as a software-as-a-medical-device for use in children 2 years and older for diagnosing obstructive sleep apnea (OSA). To our knowledge this sHSAT has not been tested on children concurrent with the gold standard polysomnography (PSG). Methods This study evaluated 50 children 2-6 years of age with tonsillar hypertrophy and OSA symptoms with sHSAT during simultaneous in-lab PSG. Aims were to determine the technical feasibility of using sHSAT in this population and to compare sHSAT results to PSG. The primary endpoint was AHI by sHSAT compared to AHI by PSG and presence of OSA. Sensitivity analysis was performed for presence or absence of OSA diagnosis based on sHSAT versus PSG. Bland-Altman and concordance correlation calculations were used for comparisons. Results 50 patients, median age 4 (IQR 3-5), met criteria; 39 completed PSG and HSAT. The sensitivity with sHSAT for OSA prevalence based on proprietary categorization was 94.1%, specificity 22.7%, LR+ 1.22, and LR- 0.26, with PSG OSA prevalence of 43.6%. There was a 9% sHSAT total failure rate, and the device frequently fell off, resulting in TST difference of -226.9 ±182.8 min between sHSAT and PSG. PSG was trimmed to include only segments where HSAT was confirmed to be on before comparisons. Concordance correlation coefficient between sAHI and AHI-PSG was 0.52. The Bland-Altman analysis comparing sAHI and PSG AHI revealed a mean difference of 0.73 (95% confidence limits: -3.47 to 4.93). Considering only obstructive events, the Bland-Altman the sAHI vs the AHI-PSG shows a mean difference of 1.52 (95%CI -5.40 to 8.44). Conclusion This pilot study demonstrated challenges with feasibility in using the sHSAT in this age group given likelihood of technical difficulties leading to absent or truncated data. When compared with PSG, sHSAT demonstrated a high false-positive rate for diagnosis of OSA, particularly concerning if guiding surgical management. This topic is of considerable importance to the practice of pediatric sleep medicine; further investigation of technological advances in this area is imperative. Support (if any)

ImportanceVestibular migraine has no established treatments.ObjectiveTo test the efficacy of rizatriptan for treating vestibular migraine attacks.Design, Setting, and ParticipantsThis double-blind, randomized clinical trial of rizatriptan vs placebo was conducted from December 2014 through July 2020 (data analyses in 2021 and sensitivity analyses in 2022 and 2024) at 2 tertiary neurotologic centers. Adults with vestibular migraine were included.InterventionAll participants underwent prospective observation to confirm diagnosis and illness activity and were then randomized in a 2:1 ratio to receive rizatriptan 10 mg or placebo to treat up to 3 vestibular migraine attacks per participant.Main Outcomes and MeasuresParticipants rated symptoms as absent, mild, moderate, or severe at scheduled intervals. Primary outcomes were the percentage of attacks with reductions in vertigo and unsteadiness/dizziness from moderate or severe to absent or mild at 1 hour. Secondary outcomes were the percentage of attacks with complete resolution of vestibular symptoms at 1 hour; reductions in headache and associated symptoms at 1 hour; use of rescue medications after 1 hour; reductions in vestibular, headache, and associated symptoms at 24 hours without rescue medications; treatment satisfaction and quality of life at 48 hours; and rates of serious adverse effects and discontinuation due to adverse effects.ResultsOf 222 total participants (mean [SD] age, 42.3 [11.7] years; 70.7% were women), 134 (60.4%) with active illness treated 307 attacks. Efficacy was tested using 240 attacks with vestibular symptoms rated as moderate or severe when participants took study drug. At 1 hour, rizatriptan did not differ from placebo for reducing vertigo (73/151 [48.3%] vs 50/88 [56.8%] attacks; odds ratio [OR], 0.71 [95% CI, 0.42-1.21]), unsteadiness/dizziness (29/151 [19.2%] vs 11/89 [12.4%] attacks; OR, 1.69 [95% CI, 0.80-3.57]), or any secondary outcomes. Similar percentages of participants in rizatriptan and placebo groups (26.4% for both groups) added rescue remedies after 1 hour. At 24 hours, rizatriptan had medium effects over placebo for unsteadiness/dizziness (OR, 2.65) and motion sensitivity (OR, 3.58). Post hoc analyses of all treated attacks found a medium effect favoring rizatriptan for headache and photophobia or phonophobia at 24 hours. Treatment satisfaction was equivocal. Quality of life was mixed. No participants experienced serious adverse effects or discontinued treatment for adverse effects.Conclusions and RelevanceIn this study, rizatriptan was ineffective at 1 hour for treating vestibular migraine attacks and had limited benefit on symptoms at 24 hours. Findings do not support using rizatriptan for vestibular migraine attacks.Trial RegistrationClinicalTrials.gov Identifier: NCT02447991

Objective: To examine the impact of in-utero exposure to dolutegravir (DTG)-based or efavirenz (EFV)-based antiretroviral treatment (ART) on child neurodevelopmental outcomes. Design: Prospective cohort design, enrolling three cohorts of 2-year-olds: children HIV-negative born to mothers with HIV (CHEU) receiving either DTG-based or EFV-based three-drug ART during pregnancy, and children born to mothers without HIV (CHUU). Methods: Primary child neurodevelopmental outcomes were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) and compared between cohorts using generalized estimating equation models adjusted for confounders. Children were classified as having an ‘adverse ND outcome’ if they scored at least 1 standard deviation (SD) below the mean or were unable to complete the BSID-III. Results: Five hundred and sixty-four participants (202 DTG-exposed, 202 EFV-exposed, 160 HIV-unexposed; mean age 25.7 months, 49% female). Mean (SD) Gross Motor scores were slightly lower among CHEU vs. CHUU [54.6 (3.6) vs. 55.6 (4.3)] and among EFV-exposed vs. DTG-exposed [54.3 (3.5) vs. 54.9 (3.6)]. CHEU were more likely to be classified as having an ‘adverse’ expressive language outcome [13.2 vs 7%, adjusted risk ratio (aRR) = 2.06, 95% confidence interval (CI) 1.05–4.03] than CHUU, but other neurodevelopmental outcomes were similar. DTG exposure was associated with less frequent ‘adverse’ classification in Cognitive (2.5 vs. 7.4%, aRR = 0.33, 95% CI 0.13–0.79) and Expressive Language domains (10.0 vs. 16.4%, aRR = 0.58, 95% CI 0.35, 0.95), compared to EFV exposure. Conclusion: Two-year neurodevelopmental outcomes among Botswana children DTG-exposed, EFV-exposed, and HIV-unexposed were mostly comparable. Children exposed in utero to EFV-based ART had higher risk of ‘adverse’ cognitive and expressive language outcomes compared with children DTG-exposed.

Background: While criteria for the diagnosis of nosocomial pneumonias exist, objective definitions are a challenge and there is no gold standard for diagnosis. We analyzed the impact of the implementation of a logical, consensus-based diagnostic and treatment protocol for managing nosocomial pneumonias in the cardiovascular surgery intensive care unit (CVS-ICU). Methods: We conducted a quasi-experimental, interrupted time series analysis to evaluate the impact of a diagnostic and treatment protocol for nosocomial pneumonias in the CVS-ICU. Impacts were measured relative to patient outcomes, diagnostic processes, and antimicrobial stewardship improvement. Descriptive statistics were used to analyze results. Results: Overall, 35 pre-protocol and 39 post-protocol patients were included. Primary clinical variables suggesting pneumonia in pre- and post-protocol patients were new lung consolidation (50% vs. 71%), new leukocytosis (59% vs. 64%), and positive culture (32% vs. 55%). Appropriate diagnostic testing improved (23% vs. 54%, p = 0.008) after protocol implementation. The proportion of patients meeting the criteria for nosocomial pneumonia (77% vs. 87%) was not statistically significant, though more patients in the post-protocol group met probable diagnostic criteria (51% vs. 77%). Duration of therapy was not significantly different (6 days [IQR = 5.0, 10.0] vs. 7 days [IQR = 6.0, 9.0]). Conclusions: The implementation of a diagnostic and treatment protocol for management of nosocomial pneumonias in the CVS-ICU resulted in improved diagnostic accuracy, advanced antimicrobial and diagnostic stewardship efforts, and laboratory cost savings without an adverse impact on patient-centered outcomes.

Introduction Subjectively experienced cognitive difficulties are common in youth with postural orthostatic tachycardia syndrome. The pathophysiological and psychological contributions of these cognitive impairments remain unclear. Method Participants were 96 adolescents and young adults diagnosed with postural orthostatic tachycardia syndrome and admitted to an intensive pain treatment program. Participants completed cognitive assessment and measures of postural orthostatic tachycardia syndrome symptoms, pain intensity, pain catastrophizing, anxiety, depression, and functional disability. Results Self-reported autonomic symptom intensity, but not severity of heart rate change, was associated with cognitive performance. Symptoms of depression were associated with decreases in most measures of cognitive functioning. Pain intensity, pain catastrophizing, and depression but not cognitive scores and physiological measures, were significant predictors of disability. Conclusion Depression appears to be a significant contributor to the cognitive difficulties in youth with postural orthostatic tachycardia syndrome. These findings highlight the importance of assessing and treating affective symptoms in this population along with medical and lifestyle approaches to treating postural orthostatic tachycardia syndrome symptoms.
