Early-stage breast cancer menopausal symptom experience and management: exploring medical oncology clinic visit conversations through qualitative analysis.

PURPOSE: Women being treated with chemotherapy for breast cancer experience menopausal symptoms that vary in presentation and impact on quality of life. The clinical visit before each chemotherapy cycle provides an important opportunity to allow patients to dialogue with their medical oncology healthcare providers about these symptoms and identify strategies for self-management. The objective of this study was to characterize patient and provider interactions regarding the menopausal symptom experience and management in the context of breast cancer treatment. METHODS: Thematic analysis was employed to analyze 61 transcripts from clinical encounters of women receiving chemotherapy treatment for breast cancer. Transcripts were chosen based on their inclusion of menopausal symptom discussion. RESULTS: Themes were separated into three distinct categories: patient, clinician, and dyadic themes. The overarching theme was goal discordance in the clinical visit, which was reflected in the following themes: unexpected and unprepared; distressed, disrupted and disturbed; clinical insensitivity; missed opportunity for management and empathy; and use of humor and colloquial language. Overall, women were unprepared for the menopausal symptom experience, and clinicians did not often provide management, interventions, or empathetic responses. CONCLUSION: There is a need to develop more astute assessment and communication regarding menopausal symptoms during the clinical visit. Possible interventions include a more holistic assessment, algorithms to facilitate the clinician's attention and response to menopausal symptoms, and treatment of symptoms.

Sleep Environments of Children in an Urban U.S. Setting Exposed to Interpersonal Violence.

This study investigated how violence influences children's sleep environments. Sixty-five children ages 8-16 years and a parent or guardian were recruited from agencies serving families experiencing violence. At baseline (5 weeks post-violent event), 6 months, and 12 months postbaseline, study staff collected sleep-behavior information and conducted systematic, qualitative assessments of sleep environments. Child sleep problems were generally frequent and persistent. However, 9 children reported improved sleep after the violent event, mainly because perpetrators were no longer present. Sleeping environments were dynamic via changes in location and modifications to improve safety and sleep. Incongruence between children's and parents' perceptions of environmental characteristics influencing sleep was common. Families' motivation to improve children's sleep represents a foundation to build upon when working with families victimized by violence.

Association between children's exposure to a violent event and objectively and subjectively measured sleep characteristics: a pilot longitudinal study.

Although sleep disturbances are commonly reported among children exposed to violence, objective evidence of such disturbances is rare. This longitudinal, home-based study assessed the effects of a known community- or family-violence incident on both actigraphy-derived and subjectively reported sleep outcomes of an ethnically mixed, urban sample of children aged 8-16 years. We hypothesized that increased event severity (child physical assault, witnessed homicide) would be associated with lower sleep duration and poorer sleep quality both at baseline and at 3-month follow-up. Covariate-adjusted analyses based on a generalized estimating equations approach showed that children physically assaulted during the event showed lower sleep duration and sleep efficiency and greater wake after sleep onset than those not physically assaulted. Physically assaulted children were more likely to have a later bedtime than non-assaulted children, but this difference decreased at 3 months. Children witnessing a homicide showed greater wake after sleep onset at baseline and reported greater sleep problems than those witnessing a non-homicide event, but these differences decreased at 3 months. They were also somewhat more likely to have greater nightly variation in sleep duration. Collectively, results suggest that violence exposure influences children's sleep, but that specific dimensions of sleep may exhibit different susceptibility to different characteristics of violence, especially over time.

Human embryonic stem cell-derived oligodendrocyte progenitor cell transplants improve recovery after cervical spinal cord injury.

Evidence that cell transplants can improve recovery outcomes in spinal cord injury (SCI) models substantiates treatment strategies involving cell replacement for humans with SCI. Most pre-clinical studies of cell replacement in SCI examine thoracic injury models. However, as most human injuries occur at the cervical level, it is critical to assess potential treatments in cervical injury models and examine their effectiveness using at-level histological and functional measures. To directly address cervical SCI, we used a C5 midline contusion injury model and assessed the efficacy of a candidate therapeutic for thoracic SCI in this cervical model. The contusion generates reproducible, bilateral movement and histological deficits, although a number of injury parameters such as acute severity of injury, affected gray-to-white matter ratio, extent of endogenous remyelination, and at-level locomotion deficits do not correspond with these parameters in thoracic SCI. On the basis of reported benefits in thoracic SCI, we transplanted human embryonic stem cell (hESC)-derived oligodendrocyte progenitor cells (OPCs) into this cervical model. hESC-derived OPC transplants attenuated lesion pathogenesis and improved recovery of forelimb function. Histological effects of transplantation included robust white and gray matter sparing at the injury epicenter and, in particular, preservation of motor neurons that correlated with movement recovery. These findings further our understanding of the histopathology and functional outcomes of cervical SCI, define potential therapeutic targets, and support the use of these cells as a treatment for cervical SCI.

Thrust force characterization of free-swimming soft robotic jellyfish.

Five unique soft robotic jellyfish were manufactured with eight pneumatic network tentacle actuators extending radially from their centers. These jellyfish robots were able to freely swim untethered in the ocean, to steer from side to side, and to swim through orifices more narrow than the nominal diameter of the jellyfish. Each of the five jellyfish robots were manufactured with a different composition of body and tentacle actuator Shore hardness. A three-factor study was performed with these five jellyfish robots to determine the impact that actuator material Shore hardness, actuation frequency, and tentacle stroke actuation amplitude had upon the measured thrust force. It was found that all three of these factors significantly impacted mean thrust force generation, which peaked with a half-stroke actuation amplitude at a frequency of 0.8 Hz.

Human motor neuron progenitor transplantation leads to endogenous neuronal sparing in 3 models of motor neuron loss.

Motor neuron loss is characteristic of many neurodegenerative disorders and results in rapid loss of muscle control, paralysis, and eventual death in severe cases. In order to investigate the neurotrophic effects of a motor neuron lineage graft, we transplanted human embryonic stem cell-derived motor neuron progenitors (hMNPs) and examined their histopathological effect in three animal models of motor neuron loss. Specifically, we transplanted hMNPs into rodent models of SMA (Δ7SMN), ALS (SOD1 G93A), and spinal cord injury (SCI). The transplanted cells survived and differentiated in all models. In addition, we have also found that hMNPs secrete physiologically active growth factors in vivo, including NGF and NT-3, which significantly enhanced the number of spared endogenous neurons in all three animal models. The ability to maintain dying motor neurons by delivering motor neuron-specific neurotrophic support represents a powerful treatment strategy for diseases characterized by motor neuron loss.

Organizational downsizing and age discrimination litigation: the influence of personnel practices and statistical evidence on litigation outcomes.

The present study examined relationships between reduction-in-force (RIF) personnel practices, presentation of statistical evidence, and litigation outcomes. Policy capturing methods were utilized to analyze the components of 115 federal district court opinions involving age discrimination disparate treatment allegations and organizational downsizing. Univariate analyses revealed meaningful links between RIF personnel practices, use of statistical evidence, and judicial verdict. The defendant organization was awarded summary judgment in 73% of the claims included in the study. Judicial decisions in favor of the defendant organization were found to be significantly related to such variables as formal performance appraisal systems, termination decision review within the organization, methods of employee assessment and selection for termination, and the presence of a concrete layoff policy. The use of statistical evidence in ADEA disparate treatment litigation was investigated and found to be a potentially persuasive type of indirect evidence. Legal, personnel, and evidentiary ramifications are reviewed, and a framework of downsizing mechanics emphasizing legal defensibility is presented.
