RESUMO

Introduction: Mental health issues have been on the rise among children and adolescents, and digital parenting programs have shown promising outcomes. However, there is limited research on the potential efficacy of utilizing chatbots to promote parental skills. This study aimed to understand whether parents learn from a parenting chatbot micro intervention, to assess the overall efficacy of the intervention, and to explore the user characteristics of the participants, including parental busyness, assumptions about parenting, and qualitative engagement with the chatbot. Methods: A sample of 170 parents with at least one child between 2-11 years old were recruited. A randomized control trial was conducted. Participants in the experimental group accessed a 15-min intervention that taught how to utilize positive attention and praise to promote positive behaviors in their children, while the control group remained on a waiting list. Results: Results showed that participants engaged with a brief AI-based chatbot intervention and were able to learn effective praising skills. Although scores moved in the expected direction, there were no significant differences by condition in the praising knowledge reported by parents, perceived changes in disruptive behaviors, or parenting self-efficacy, from pre-intervention to 24-hour follow-up. Discussion: The results provided insight to understand how parents engaged with the chatbot and suggests that, in general, brief, self-guided, digital interventions can promote learning in parents. It is possible that a higher dose of intervention may be needed to obtain a therapeutic change in parents. Further research implications on chatbots for parenting skills are discussed.

RESUMO

OBJECTIVE: To evaluate a precise definition of a clinically significant cardiopulmonary event (CSCPE) on the hospital length of stay (LOS), medical provider satisfaction, and discharge complications. STUDY DESIGN: This is a single-center, observational study that included 139 infants before and 134 infants after the new definition was implemented in December 2017. Retrospective data collected November 2015 to November 2017 (before) was compared with prospective data from June 2018 to July 2020 (after). Outcome measures were the proportion of infants waiting to outgrow CSCPE, LOS, provider satisfaction with the definition, and discharge complications. Multivariate regression modeling was used to evaluate variables on LOS and postmenstrual age at discharge. RESULTS: The proportion waiting to outgrow CSCPE decreased from 68.4% to 31.7% (P < .0001). The LOS was similar between groups; however, multivariate analysis correcting for gestational age and reason awaiting discharge estimated 3.5 days (95% CI, 1.4-5.8 days; P = .0017) decrease in LOS, and 0.92 weeks (95% CI, 0.29-1.56; P = .005) younger postmenstrual age at discharge in the after group. There was no difference in the number of readmissions or emergency room visits for apnea or deaths. Provider satisfaction improved with discharge planning after the implementation of the definition. CONCLUSIONS: We developed an alternate definition for a CSCPE that decreased the proportion of infants waiting to outgrow a CSCPE but not LOS. There was no difference in the number of readmissions or emergency room visits for apnea or deaths, and provider satisfaction in management and discharge planning was greater. CLINICAL TRIAL REGISTRATION INFORMATION: This study was registered under the ClinicalTrial.gov Protocol ID: 5892S-15. "The effect of standardizing the definition and approach to a clinically significant cardiopulmonary event in infants less than 30 weeks on length of stay." Recorded Nov 2017.

RESUMO

The tyrosine kinase inhibitor sorafenib improves hepatopulmonary syndrome (HPS) in an experimental model. However, the efficacy and adverse effect profile in patients with HPS are unknown. We aimed to determine the effect of sorafenib on the alveolar-arterial oxygen gradient (AaPO2 ) at 3 months in patients with HPS. We performed a randomized, double-blind, placebo-controlled parallel trial of sorafenib in patients with HPS at 7 centers. A total of 28 patients with HPS were randomized to sorafenib 400 mg by mouth daily or a matching placebo in a 1:1 ratio. We found no statistically significant difference in the median change in AaPO2 from baseline to 12 weeks between the patients allocated to sorafenib (4.5 mm Hg; IQR, -3.8 to 7.0 mm Hg) and those allocated to placebo (-2.4 mm Hg; IQR, -4.8 to 8.2 mm Hg; P = 0.70). There was also no difference between the groups in terms of degree of intrapulmonary shunting by contrast echocardiography. Sorafenib significantly reduced circulating levels of angiogenic markers, including vascular endothelial growth factor receptors (P < 0.01) and TIE2-expressing M2 monocytes (P = 0.03), but it reduced the mental component scores of the Short Form 36 (P = 0.04), indicating a worse quality of life. In conclusion, sorafenib did not change the AaPO2 or other disease markers at 3 months in patients with HPS. Alternative antiangiogenic therapies or treatments targeting other pathways should be investigated.

RESUMO

Screening for hepatopulmonary syndrome (HPS) using pulse oximetry is recommended in liver transplant (LT) candidates because mortality is increased, independently of the severity of the oxygenation defect. LT exception points may be afforded to those with HPS and severe hypoxemia. We assessed the screening characteristics of pulse oximetry for HPS. The Pulmonary Vascular Complications of Liver Disease 2 study is a multicenter, prospective cohort study of adults undergoing their first LT evaluation. Patients underwent protocolized assessment of oxygen saturation by pulse oximetry (SpO2 ), arterial blood gas, spirometry, and contrast-enhanced echocardiography (CE). HPS was defined as an alveolar-arterial gradient ≥15 mm Hg (≥20 mm Hg if age >64 years), intrapulmonary vascular dilatation on CE, and absence of lung disease. The study sample included 363 patients. Of these, 75 (20.7%; 95% confidence interval [CI], 16.6%-25.2%) met the criteria for HPS. The area under the receiver operating characteristic curve (or c-statistic) for SpO2 in discriminating HPS was 0.59 (95% CI, 0.51-0.66). An SpO2 <96%, recommended by practice guidelines as a threshold to require further testing, had low sensitivity (28%; 95% CI, 18%-28%). The c-statistic of SpO2 in discriminating HPS with a partial pressure of oxygen (PaO2 ) <60 mm Hg (eligible for LT exception points) was 0.76 (95% CI, 0.46-1.00). An SpO2 cutoff of <96% had higher sensitivity for detecting HPS with PaO2 <60 mm Hg (71%; 95% CI, 38%-100%) but was still inadequate. Conclusion: Pulse oximetry is not sufficiently sensitive to screen for HPS in LT candidates. Arterial blood gas and CE are required in LT candidates for diagnosis of HPS.
