UNSTRUCTURED Although hyperactivity is a core symptom of ADHD, there are no objective measures that are widely used in clinical settings. We describe the development of a smartwatch application to measure hyperactivity in school-age children. The LemurDx prototype is a software system for smartwatches that uses wearable sensor technology and machine learning (ML) to measure hyperactivity, with the goal of differentiating children with ADHD combined presentation or predominantly hyperactive/impulsive presentation from children with typical levels of activity. In this pilot study, we recruited 30 children (ages 6-11) to wear the smartwatch with the LemurDx app for two days. Parents also provided activity labels for 30-minute intervals to help train the algorithm. Half the sample had ADHD combined presentation or predominantly hyperactive/impulsive presentation (n = 15) and half were healthy controls (n = 15). Results indicated high usability scores and an overall diagnostic accuracy of .89 (sensitivity = .93; specificity = .86) when the motion sensor output was paired with the activity labels, suggesting that state-of-the-art sensors and ML may provide a promising avenue for the objective measurement of hyperactivity.

Efficacy Of Treatment

Abstract. Background: Previous suicide attempts increase the risk of a completed suicide. However, a large proportion of patients with deliberate self-wrist cutting (DSWC) are often discharged without undergoing a psychiatric interview. Aims: The aims of this study were to investigate the differences in the characteristics and outcomes of patients with DSWC and those with deliberate self-poisoning (DSP) episodes. The results of this study may be used to improve the efficacy of treatment for DSWC patients. Method: We retrospectively reviewed the medical records of 598 patients with DSWC and DSP who were treated at the emergency department of Seoul Saint Mary's Hospital between 2008 and 2013. We assessed sociodemographic information, clinical variables, the reasons for the suicide attempts, and the severity of the suicide attempts. Results: A total of 141 (23.6%) patients were included in the DSWC group, and 457 (76.4%) were included in the DSP group. A significantly greater number of patients in the DSWC group had previously attempted suicide (p = .014). A total of 63 patients (44.7%) in the DSWC group and 409 patients (89.5%) in the DSP group underwent psychiatric interviews. Conclusion: More DSWC patients had previously attempted suicide, but fewer of them underwent psychiatric interviews compared with the DSP patients.

Background: The international literature reports that for every completed suicide there are between 8 and 22 visits to an Emergency Department (ED) for attempted suicide/suicidal behavior. Aims: To describe the characteristics of admission to emergency departments (EDs) for suicide-related presenting complaints in the metropolitan area of Bologna; to estimate the risk for all-cause mortality and for suicide; to identify the profiles of subjects most at risk. Method: Follow-up of patients admitted to the EDs of the metropolitan area of Bologna between January 2004 and December 2010 for attempted suicide. A Cox model was used to evaluate the association between sociodemographic variables and the general mortality risk. Results: We identified 505 cases of attempted suicide, which were more frequent for female subjects, over the weekend, and at night (8:00 p.m./8:00 a.m.). The most used suicide methods were psychotropic drugs, sharp or blunt objects, and jumping from high places. In this cohort, 3.6% of subjects completed suicide (4.5% of males vs. 2.9% of females), 2.3% within 1 year of the start of follow-up. The most common causes of death were drug use and hanging. In the multivariate analysis, those who used illicit drugs 24 hr prior to admission to the ED (hazard ratio [HR] = 3.46, 95% CI = 1.23–9.73) and patients who refused the treatment (HR = 6.74, 95% CI = 1.86–24.40) showed an increased mortality risk for suicide. Conclusion: Deliberate self-harm patients presenting to the ED who refuse treatment represent a specific target group for setting up dedicated prevention schemes.
