Study Objectives Consumer sleep-tracking devices are widely used and becoming more technologically advanced, creating strong interest from researchers and clinicians for their possible use as alternatives to standard actigraphy. We, therefore, tested the performance of many of the latest consumer sleep-tracking devices, alongside actigraphy, versus the gold-standard sleep assessment technique, polysomnography (PSG). Methods In total, 34 healthy young adults (22 women; 28.1 ± 3.9 years, mean ± SD) were tested on three consecutive nights (including a disrupted sleep condition) in a sleep laboratory with PSG, along with actigraphy (Philips Respironics Actiwatch 2) and a subset of consumer sleep-tracking devices. Altogether, four wearable (Fatigue Science Readiband, Fitbit Alta HR, Garmin Fenix 5S, Garmin Vivosmart 3) and three nonwearable (EarlySense Live, ResMed S+, SleepScore Max) devices were tested. Sleep/wake summary and epoch-by-epoch agreement measures were compared with PSG. Results Most devices (Fatigue Science Readiband, Fitbit Alta HR, EarlySense Live, ResMed S+, SleepScore Max) performed as well as or better than actigraphy on sleep/wake performance measures, while the Garmin devices performed worse. Overall, epoch-by-epoch sensitivity was high (all ≥0.93), specificity was low-to-medium (0.18–0.54), sleep stage comparisons were mixed, and devices tended to perform worse on nights with poorer/disrupted sleep. Conclusions Consumer sleep-tracking devices exhibited high performance in detecting sleep, and most performed equivalent to (or better than) actigraphy in detecting wake. Device sleep stage assessments were inconsistent. Findings indicate that many newer sleep-tracking devices demonstrate promising performance for tracking sleep and wake. Devices should be tested in different populations and settings to further examine their wider validity and utility.
Adolescent and young adult women are disproportionately burdened by violence at the hands of dating and intimate partners. Evidence supports routine screening in clinical settings for detection and intervention. Although screening for intimate partner violence in reproductive health care settings is widely endorsed, little is known about screening practices. We conducted qualitative in-depth interviews with healthcare providers (n = 14) in several urban reproductive health clinics in Baltimore City, Maryland to understand screening practices, including related barriers and motivations. Interviews were transcribed verbatim and analyzed using inductive content analysis. Findings demonstrated substantial variation in screening practices as well as related referral and follow-up, despite the existence of a screening tool. Factors that appeared to undermine consistent and successful screening implementation included lack of a common goal for screening, lack of clarity in staff roles, a gap in on-site support services, as well as lack of time and confidence. Findings affirm the value of applying a systems model to intimate partner violence (IPV) screening programs. This research advances the understanding of the implementation challenges for violence-related screening for high-risk populations such as adolescents and young adults in reproductive health care settings and is particularly relevant given the recent endorsement by the DHHS to cover IPV screening under the Affordable Care Act.
This study demonstrates the successful management of aggressive behaviour with a client 10 years post-injury in a small, residential neurorehabilitation unit. The case presented is unusual for two main reasons. First, it proved possible to significantly modify previously chronic challenging behaviour many years after brain injury had been sustained. Secondly, the rehabilitation environment in which treatment was conducted did not comprise a highly specialized neurobehavioural service, Instead, staff were specifically trained regarding the administration of the treatment programme, which was based on principles derived from behaviour modification and applied neuropsychology. Specific interventions used included those of differential reinforcement and graduated increase of expectations. Recordings made over the course of 85 weeks demonstrate a significant decrease in the frequency and severity of aggression. Successful inhibition of challenging behaviour attained a level which facilitated transfer of the client to a non-institutionalized community home. Reasons underlying the success of the intervention, and the limitations inherent in attempting to manage aggression within neurorehabilitation environments will be discussed.
Women serve as important health information sources for young men. No previous study has explored women's perceptions about this role related to young men's sexual and reproductive health (SRH) care. Twenty African American women recruited from two clinics participated in three focus groups to explore perceptions to engage young men in SRH care. Themes were identified that may facilitate and/or hinder women to engage young men in SRH care: 1) communication/actions to provide support; 2) challenges in providing support; 3) traditional gender role perceptions and other access barriers; and 4) motivation, influence and control. Participants were interested and willing to support young men's SRH including sharing information about clinics (95%), making appointments (90%), going to visits together (90%), and having joint appointments (67%). Findings provide a foundation for programs interested to engage women as health promotion agents to improve young men's SRH care access. Future efforts should explore the generalizability of study findings.
Young women engaged in exotic dancing have a higher need for reproductive health services than women not in this profession, and many also use drugs or exchange sex for money or drugs. Few report receiving reproductive health services. We describe a public health, academic, and community partnership that provided reproductive health services on needle exchange mobile vans in the “red light district” in downtown Baltimore, Maryland. Women made 220 visits to the vans in the first 21 months of the program’s operation, and 65% of these visits involved provision of contraception. Programmatic costs were feasible. Joint provision of needle exchange and reproductive health services targeting exotic dancers has the potential to reduce unintended pregnancies and link pregnant, substance-abusing women to reproductive care, and such programs should be implemented more widely.
Objectives: To evaluate the outbreak size and hospital cost effects of bacterial whole-genome sequencing availability in managing a large-scale hospital outbreak.Methods: We built a hybrid discrete event/agent-based simulation model to replicate a serious bacterial outbreak of resistant Escherichia coli in a large metropolitan public hospital during 2017. We tested the 3 strategies of using whole-genome sequencing early, late (actual outbreak), or not using it and assessed their associated outbreak size and hospital cost. The model included ward dynamics, pathogen transmission, and associated hospital costs during a 5-month outbreak. Model parameters were determined using data from the Queensland Hospital Admitted Patient Data Collection (N = 4809 patient admissions) and local clinical knowledge. Sensitivity analyses were performed to address model and parameter uncertainty.Results: An estimated 197 patients were colonized during the outbreak, with 75 patients detected.
Background Diphtheria is a potentially fatal respiratory disease caused by toxigenic Corynebacterium diphtheriae. Although resistance to erythromycin has been recognised, β-lactam resistance in toxigenic diphtheria has not been described. Here, we report a case of fatal respiratory diphtheria caused by toxigenic C. diphtheriae resistant to penicillin and all other β-lactam antibiotics and describe a novel mechanism of inducible carbapenem resistance associated with the acquisition of a mobile resistance element. Methods Long-read whole genome sequencing was performed using Pacific Biosciences SMRT sequencing to determine the genome sequence of C. diphtheriae BQ11 and mechanism of β-lactam resistance. To investigate phenotypic inducibility of meropenem resistance, short read sequencing was performed using an Illumina NextSeq500 sequencer on the strain with and without exposure to meropenem. Results BQ11 demonstrated high-level resistance to penicillin (benzylpenicillin MIC ≥ 256 μg/ml), β-lactam/β-lactamase inhibitors and cephalosporins (amoxicillin/clavulanic acid MIC ≥ 256 μg/mL; ceftriaxone MIC ≥ 8 μg/L). Genomic analysis of BQ11 identified acquisition of a novel transposon carrying the penicillin binding protein Pbp2c, responsible for resistance to penicillin and cephalosporins. When strain BQ11 was exposed to meropenem, selective pressure drove amplification of the transposon in a tandem array and led to a corresponding change from a low level to high level meropenem resistant phenotype. Conclusions We have identified a novel mechanism of inducible antibiotic resistance whereby isolates that appear to be carbapenem susceptible on initial testing can develop in vivo resistance to carbapenems with repeated exposure. This phenomenon could have significant implications for treatment of C. diphtheriae infection and may lead to clinical failure.
