Personal sensing, leveraging data passively and near-continuously collected with wearables from patients in their ecological environment, is a promising paradigm to monitor mood disorders (MDs), major determinant of worldwide disease burden. However, collecting annotating wearable very resource-intensive. Studies this kind can thus typically afford recruit only couple dozens patients. This constitutes one the obstacles applying modern supervised machine learning techniques MDs detection. In paper, we overcome bottleneck advance detection acute episode vs stable state on back recent advances self-supervised (SSL). leverages unlabelled learn representations during pre-training, subsequently exploited for task. First, open-access datasets recording an Empatica E4 spanning different, unrelated MD monitoring, personal sensing tasks -- emotion recognition Super Mario players stress undergraduates devised pre-processing pipeline performing on-/off-body detection, sleep-wake segmentation, (optionally) feature extraction. With 161 E4-recorded subjects, introduce E4SelfLearning, largest date open access collection, its pipeline. Second, show that SSL confidently outperforms fully-supervised pipelines using either our novel E4-tailored Transformer architecture (E4mer) or classical baseline XGBoost: 81.23% against 75.35% 72.02% (XGBoost) correctly classified segments 64 (half acute, half stable) Lastly, illustrate performance strongly associated specific surrogate task employed pre-training as well availability.

Depressive and manic episodes within bipolar disorder (BD) major depressive (MDD) involve altered mood, sleep, activity, alongside physiological alterations wearables can capture. Firstly, we explored whether wearable data could predict (aim 1) the severity of an acute affective episode at intra-individual level 2) polarity euthymia among different individuals. Secondarily, which were related to prior predictions, generalization across patients, associations between symptoms data. We conducted a prospective exploratory observational study including patients with BD MDD on (manic, depressed, mixed) whose recorded using research-grade (Empatica E4) 3 consecutive time points (acute, response, remission episode). Euthymic healthy controls during single session (approximately 48 h). Manic assessed standardized psychometric scales.

Mood disorders (MDs) are among the leading causes of disease burden worldwide. Limited specialized care availability remains a major bottleneck thus hindering pre-emptive interventions. MDs manifest with changes in mood, sleep, and motor activity, observable ecological physiological recordings thanks to recent advances wearable technology. Therefore, near-continuous passive collection data from wearables daily life, analyzable machine learning (ML), could mitigate this problem, bringing monitoring outside clinician's office. Previous works predict single label, either state or psychometric scale total score. However, clinical practice suggests that same label may underlie different symptom profiles, requiring specific treatments. Here we bridge gap by proposing new task: inferring all items HDRS YMRS, two most widely used standardized scales for assessing symptoms, using wearables. To end, develop deep pipeline score symptoms large cohort MD patients show agreement between predictions assessments an expert clinician is clinically significant (quadratic Cohen's κ macro-average F1 both 0.609). While doing so, investigate several solutions ML challenges associated task, including multi-task learning, class imbalance, ordinal target variables, subject-invariant representations. Lastly, illustrate importance testing on out-of-distribution samples.

Major depressive disorder (MDD) is a recurrent episodic mood that represents the third leading cause of disability worldwide. In MDD, several factors can simultaneously contribute to its development, which complicates diagnosis. According practical guidelines, antidepressants are first-line treatment for moderate severe major episodes. Traditional strategies often follow one-size-fits-all approach, resulting in suboptimal outcomes many patients who fail experience response or recovery and develop so-called “therapy-resistant depression”. The high biological clinical inter-variability within lack robust biomarkers hinder finding specific therapeutic targets, contributing failure rates. this frame, precision medicine, paradigm tailors medical interventions individual characteristics, would help allocate most adequate effective each patient while minimizing side effects. particular, multi-omic studies may unveil intricate interplays between genetic predispositions exposure environmental through study epigenomics, transcriptomics, proteomics, metabolomics, gut microbiomics, immunomics. integration flow information into molecular pathways produce better than current psychopharmacological targets singular mainly related monoamine systems, disregarding complex network our organism. concept system biomedicine involves analysis enormous datasets generated with different technologies, creating “patient fingerprint”, defines underlying mechanisms every patient.
