Muscle loss in elderly patients - prevention effects of a multimodal therapy program for low back pain
In this study we demonstrated that multimodal therapy is an efficient alternative intervention to strengthen the back muscles and by this to increase muscle growth in the areas of extension and flexion as well as lateralization and rotation on both sides.Material and methods52 patients aged between 50 and 65 with a main diagnosis of back disease were examined prospective. They completed a 3-week inpatient multimodal therapy program. Effects of the program were assessed by applying two isometric strength measurements of the back muscles. Baseline measurement (T0) was done on the first day of the program and post measurement...

IJERPH, Vol. 16, Pages 4300: Patient Perspectives to Inform a Health Literacy Educational Program: A Systematic Review and Thematic Synthesis of Qualitative Studies
F. de Winter Patient-centred care is tailored to the needs of patients and is necessary for better health outcomes, especially for individuals with limited health literacy (LHL). However, its implementation remains challenging. The key to effectively address patient-centred care is to include perspectives of patients with LHL within the curricula of (future) healthcare providers (HCP). This systematic review aimed to explore and synthesize evidence on the needs, experiences and preferences of patients with LHL and to inform an existing educational framework. We searched three databases: PsychInfo, Medline and Cinahl, ...

Supervision training in healthcare: a realist synthesis
AbstractSupervision matters: it serves educational, supportive and management functions. Despite a plethora of evidence on the effectiveness of supervision, scant evidence for the impact of supervision training exists. While three previous literature reviews have begun to examine the effectiveness of supervision training, they fail to explore the extent to which supervision training works, for whom, and why. We adopted a realist approach to answer the question: to what extent do supervision training interventions work (or not), for whom and in what circumstances, and why? We conducted a team-based realist synthesis of the ...

Discordant Reporting of Partner Labels, HIV Testing and Sexual Behavior Among a Sample of Partnered Men Who have Sex with Men in the US
AbstractThere is growing evidence that sexual behaviors among male couples are strongly shaped by emotional and quality characteristics of the relationship, and that the labels that men attach to their relationships may indicate how men perceive and engage in risk taking. There has been a lack of attention to how male couples label their relationships, and how discordant understandings of relationship labels may shape HIV risk behavior. Using data from a sample of 804 partnered men who have sex with men, this analysis examines associations between discordant relationship labeling and participation in HIV testing and sexual...

Cerebral venous congestion promotes blood-brain barrier disruption and neuroinflammation, impairing cognitive function in mice
AbstractCognitive impairment is one of the most common co-occurring chronic conditions among elderly heart failure patients (incidence: up to ~ 80%); however, the underlying mechanisms are not completely understood. It is hypothesized that in addition to decreased cardiac output, increases in central —and consequentially, cerebral—venous pressure (backward failure) also contribute significantly to the genesis of cognitive impairment. To test this hypothesis and elucidate the specific pathogenic role of venous congestion in the brain, we have established a novel model of increased cerebral ve nous pressure: mice...

Network connectivity separate from the hypothesized irritative zone correlates with impaired cognition and higher rates of seizure recurrence.
CONCLUSION: Increased connectivity contralateral to seizure onset and epilepsy network spread in the bitemporal lobes correlated with lower measures of executive functioning and verbal memory. Epilepsy network localization to the bitemporal lobes, in particular, the contralateral temporal lobe, is associated with higher rates of seizure recurrence. These findings may reflect network-level disruption that has infiltrated the contralateral hemisphere and the bitemporal lobes contributing to impaired cognition and relatively worse surgical outcomes. Further identification of network parameters that predict patient outcomes ma...

Taxonomic relations evoke more fear than thematic relations after fear conditioning: An EEG study.
Abstract When fear is generalized, knowledge based on concepts is also retrieved. Concepts have two very different relations: thematic relations based on the co-occurrence of events or scenarios, and taxonomic relations based on similarity or shared features. However, it remains unclear whether thematic and taxonomic relationships differentially affect fear generalization. To clarify the underlying cognitive mechanisms of these relations, the current study combined the classical fear conditioning procedure with electroencephalography (EEG). Forty participants were conditioned to a neutral word by pairing the prese...

Age of acquisition effects differ across linguistic domains in sign language: EEG evidence.
We examined neural responses of a group of Deaf signers who received access to signed input at varying ages to three linguistic phenomena at the levels of classifier signs, syntactic structure, and information structure. The amplitude of the N400 response to the marked word order condition negatively correlated with the age of acquisition for syntax and information structure, indicating increased cognitive load in these conditions. Additionally, the combination of behavioral and neural data suggested that late learners preferentially relied on classifiers over word order for meaning extraction. This suggests that late acqu...

Neuropathology depends on cerebral development at insult time, but the poor correlation of neuromotor, cognitive, and behavioral disabilities in infancy with initial imaging and clinical records precludes early prognosis. The Rice-Vannucci HI procedure was applied to wild type and tissue plasminogen activator knockout (tPA-KO) mice as surrogates for human preterm (with five-day-old postnatal (P5) mice) or human term (with ten-day-old postnatal (P10) mice).

A neural model of schemas and memory encoding.
Abstract The ability to rapidly assimilate new information is essential for survival in a dynamic environment. This requires experiences to be encoded alongside the contextual schemas in which they occur. Tse et al. (Science 316(5821):76-82, 2007) showed that new information matching a preexisting schema is learned rapidly. To better understand the neurobiological mechanisms for creating and maintaining schemas, we constructed a biologically plausible neural network to learn context in a spatial memory task. Our model suggests that this occurs through two processing streams of indexing and representation, in which...

A Serotonin-Modulated Circuit Controls Sleep Architecture to Regulate Cognitive Function Independent of Total Sleep in Drosophila.
Abstract Both the structure and the amount of sleep are important for brain function. Entry into deep, restorative stages of sleep is time dependent; short sleep bouts selectively eliminate these states. Fragmentation-induced cognitive dysfunction is a feature of many common human sleep pathologies. Whether sleep structure is normally regulated independent of the amount of sleep is unknown. Here, we show that in Drosophila melanogaster, activation of a subset of serotonergic neurons fragments sleep without major changes in the total amount of sleep, dramatically reducing long episodes that may correspond to deep s...

Medical Assistance in Dying: A Point of Care Educational Framework For Attending Physicians.
Abstract Issue: Medical assistance in dying (MAID) became legal in Quebec on December 10, 2015, and in the rest of Canada on June 17, 2016. This enabled 6,749 deaths through physician-assisted suicide or euthanasia between December 10, 2015 and October 31, 2018. While the death of a patient is a common experience for medical trainees, those that occur through MAID have unique features related to the methods, the timeline, the intended role of the physician in causing the death, and the request of the patient that initiates the process. These aspects necessitate a distinct approach to MAID medical education. Eviden...
