Consumer sleep technologies (CSTs) are widespread applications and devices that purport to measure even improve sleep. Sleep clinicians may frequently encounter CST in practice and, despite lack of validation against gold standard polysomnography, familiarity with these has become a patient expectation. This American Academy Medicine position statement details the disadvantages potential benefits CSTs provides guidance when approaching patient-generated health data from clinical setting....
Abstract Wearable, multisensor, consumer devices that estimate sleep are now commonplace, but the algorithms used by these to score not open source, and raw sensor data is rarely accessible for external use. As a result, limited in their usefulness clinical research applications, despite holding much promise. We mobile application of our own creation collect acceleration heart rate from Apple Watch worn participants undergoing polysomnography, as well during ambulatory period preceding lab...
Wearable sleep-tracking technology is of growing use in the sleep and circadian fields, including for applications across other disciplines, inclusive a variety disease states. Patients increasingly present data derived from their wearable devices to providers ever-increasing availability commercial new-generation research/clinical tools has led wide adoption wearables research, which become even more relevant given discontinuation Philips Respironics Actiwatch. Standards evaluating...

Many pathogenic and commensal organisms are multidrug resistant due to exposure various antibiotics. Often, this antimicrobial resistance is encoded by integrons that occur on plasmids or integrated into the bacterial chromosome. Integrons commonly associated with genera in family Enterobacteriaceae. We determined class 1 integrases were present approximately 46% of isolates from Enterobacteriaceae; 2 only among Escherichia coli Salmonella isolates. Seven percent veterinary positive for 3...
By March 2020, COVID-19 forced much of the world to stay at home reduce spread disease. Whereas some health care workers transitioned working from home, many continued report work in person as essential employees. We sought explore changes sleep, health, work, and mood during stay-at-home orders.We developed a cross-sectional online survey administered workers. The assessed screen time, media exposure, diet, exercise, substance use, mood. data were collected between 28, April 29, 2020.A...
Polysomnography remains the cornerstone of objective testing in sleep medicine and results massive amounts electrophysiological data, which is well-suited for analysis with artificial intelligence (AI)-based tools. Combined other sources health AI expected to provide new insights inform clinical care disorders advance our understanding integral role plays human health. Additionally, has potential streamline day-to-day operations therefore optimize direct patient by team. However, clinicians,...
Sleep medicine is well positioned to benefit from advances that use big data create artificially intelligent computer programs.One obvious initial application in the sleep disorders center assisted (or enhanced) scoring of and associated events during polysomnography (PSG).This position statement outlines potential opportunities limitations integrating artificial intelligence (AI) into practice medicine.Additionally, although most apparent immediate AI our field PSG, we propose clinical...
Abstract While 24-h total sleep time (TST) is established as a critical driver of major depression, the relationships between timing and regularity mental health remain poorly characterized because most studies have relied on either self-report assessments or traditional objective measurements restricted to cross-sectional frames small cohorts. To address this gap, we assessed with wearable device, daily mood smartphone application depression through 9-item Patient Health Questionnaire...
Obstructive sleep apnea and other disorders overlap with comorbidities associated poor outcomes related to severe acute respiratory syndrome coronavirus 2 infection. However, the prevalence of obstructive among patients hospitalized for COVID-19 relationship is poorly characterized, relevance remains unknown. The objective this study was identify pre-existing association illness.Patients infection admitted University Michigan Hospital System were included. Electronic medical records queried...
Evaluate the performance of SANSA device to simultaneously assess obstructive sleep apnea (OSA) and cardiac arrhythmias. Participants suspected or known have OSA underwent polysomnography (PSG) while wearing SANSA. SANSA's algorithm was trained using 86 records tested on 67 evaluate training bias. evaluated against ground truth PSG scored by consensus three technologists. scoring from individual testing sites also consensus. Diagnostic standard apnea-hypopnea index (AHI) cutoffs. AHI total...
From smart work scheduling to optimal drug timing, there is enormous potential in translating circadian rhythms research results for precision medicine the real world. However, pursuit of such effort requires ability accurately estimate phase outside laboratory. One approach predict noninvasively using light and activity measurements mathematical models human clock. Most take as an input effect on system. consumer-grade wearables that are already owned by millions individuals record instead...
Millions of wearable-device users record their heart rate (HR) and activity. We introduce a statistical method to extract track six key physiological parameters from these data, including an underlying circadian rhythm in HR (CRHR), the direct effects activity, meals, posture, stress through hormones like cortisol. test our on over 130,000 days real-world data medical interns rotating shifts, showing that CRHR dynamics are distinct those sleep-wake or physical activity patterns vary greatly...
The aim of this research was to determine whether a seasonal pattern symptoms bulimia nervosa could be identified.In study 1, patterns binge-purge frequency and mood were compared between 31 patients with age-matched normal comparison subjects, using modified (to include binge purge items) version the Seasonal Pattern Assessment Questionnaire. Study 2 involved cross-sectional examination depressive in 197 assessed at various months year over 4-year period.In both retrospective studies,...
Fifty-eight women with anorexia or bulimia nervosa were compared 24 normal on measures of defense style and parental bonding. Results indicated that all eating-disorder subtypes exhibit more primitive defenses fewer mature ones than controls. Eating-disorder patients uniformly recalled less paternal empathy Thus, difficulties involving object representations fathers may be a theme common to eating disorders. No major differences identified among subtypes, suggesting these disorders share...
To evaluate various psychological constructs used in formulations of anorexia and bulimia nervosa, we compared 76 eating-disordered, 20 psychiatric, 24 normal women on measures irrational cognitions, object-relations disturbances, defense styles. The eating-disordered groups exhibited more disturbance all than normals many pathological elevations relative to psychiatric controls. Despite these differences, common qualitative features were identified patient groups, suggesting that based the...
