Acupuncture is a feasible alternative to procedural sedation for shoulder reduction in the emergency department.

Treating shoulder dislocations is common in the emergency department and often requires procedural sedation. The use of acupuncture for treatment of chronic pain has been shown to be successful in various outpatient settings, and some EDs have recently incorporated acupuncture as an analgesia adjunct for chronic painful conditions to avoid opioid therapy. Limited data describe acupuncture to facilitate ED procedures.

The Effect of Ketamine Versus Etomidate for Rapid Sequence Intubation on Maximum Sequential Organ Failure Assessment Score: A Randomized Clinical Trial.

Background: The use of induction agents for rapid sequence intubation (RSI) has been associated with hypotension in critically ill patients. Choice of induction agent may be important and the most commonly used agents are etomidate and ketamine.

Objective: This study aimed to compare the effects of a single dose of ketamine vs.

Remote self-administration of digital cognitive tests using the Brief Assessment of Cognition: Feasibility, reliability, and sensitivity to subjective cognitive decline.

Cognitive impairment is a common and pervasive feature of etiologically diverse disorders of the central nervous system, and a target indication for a growing number of symptomatic and disease modifying drugs. Remotely acquired digital endpoints have been recognized for their potential in providing frequent, real-time monitoring of cognition, but their ultimate value will be determined by the reliability and sensitivity of measurement in the populations of interest. To this end, we describe initial validation of remote self-administration of cognitive tests within a regulatorily compliant tablet-based platform.

Virtual Reality Functional Capacity Assessment Tool (VRFCAT-SL) in Parkinson's Disease.

Background: Cognitive impairment is common in Parkinson's disease (PD) and highly associated with loss of independence, caregiver burden, and assisted living placement. The need for cognitive functional capacity tools validated for use in PD clinical and research applications has thus been emphasized in the literature. The Virtual Reality Functional Capacity Assessment Tool (VRFCAT-SL) is a tablet-based instrument that assesses proficiency for performing real world tasks in a highly realistic environment.

Factor structure of cognitive performance and functional capacity in schizophrenia: Evidence for differences across functional capacity measures.

Background: Cognition and functional capacity predict functional outcomes in mental illness. Traditional approaches conceptualize cognition as comprised of domains, but many studies support a unifactorial structure. Some functional capacity measures may share a single-factor structure with cognition.

The Danger of Using Pop-Off Valves for Pediatric Emergency Airway Management.

Background: Most pediatric resuscitator bags are equipped with a positive-pressure relief ("pop-off") valve meant to prevent delivery of excessive pressure. Pop-off valves, however, can lead to adverse events in emergency situations when providers are unaware of their significance.

Case Report: A 3-year-old girl with muscular atrophy and a chronic tracheostomy tube was noted to have decreasing oxygen saturations.

Comprehensive review of the research employing the schizophrenia cognition rating scale (SCoRS).

This review of research utilizing the Schizophrenia Cognition Rating Scale (SCoRS) outlines the development, evaluation, validation, and implementation of the SCoRS to assess whether the scale meets the criteria as a functional co-primary as defined by the MATRICS-CT initiative. Interview-based co-primary assessments should be: 1) practical and easy to administer for a clinician or researcher; 2) validated in individuals with schizophrenia; 3) contain the relevant areas of cognition and functioning applicable to schizophrenia; 4) able to assess all phases and severity levels of schizophrenia; 5) capable of monitoring disease progression; 6) minimal burden to patients; and 7) sensitive to assess treatment effects. A review of the literature was conducted to present information on the development, psychometric properties and usage of the SCoRS.

Virtual reality assessment of functional capacity in people with Schizophrenia: Associations with reduced emotional experience and prediction of functional outcomes.

Virtual Reality (VR) approaches have had considerable success in measurement of functional capacity. However, it is not clear if factors other than cognitive impairment influence performance on VR measures. Many people with schizophrenia have significant negative symptoms and they could reduce engagement in assessment.

Serial position-dependent false memory effects.

Evidence for false recognition within seconds of encoding suggests that semantic-associative influences are not restricted to long-term memory, consistent with unitary memory accounts but contrary to dual store models. The present study sought further relevant evidence using a modified free recall converging associates task where participants studied 12-item lists composed of 3 semantically distinct quartets (sublists) related to a separate, non-presented theme word (i.e.

TOMMORROW neuropsychological battery: German language validation and normative study.

Introduction: Assessment of preclinical Alzheimer's disease (AD) requires reliable and validated methods to detect subtle cognitive changes. The battery of standardized cognitive assessments that is used for diagnostic criteria for mild cognitive impairment due to AD in the TOMMORROW study have only been fully validated in English-speaking countries. We conducted a validation and normative study of the German language version of the TOMMORROW neuropsychological test battery, which tests episodic memory, language, visuospatial ability, executive function, and attention.

Negative Symptom Dimensions of the Positive and Negative Syndrome Scale Across Geographical Regions: Implications for Social, Linguistic, and Cultural Consistency.

Recognizing the discrete dimensions that underlie negative symptoms in schizophrenia and how these dimensions are understood across localities might result in better understanding and treatment of these symptoms. To this end, the objectives of this study were to 1) identify the Positive and Negative Syndrome Scale negative symptom dimensions of expressive deficits and experiential deficits and 2) analyze performance on these dimensions over 15 geographical regions to determine whether the items defining them manifest similar reliability across these regions. Data were obtained for the baseline Positive and Negative Syndrome Scale visits of 6,889 subjects across 15 geographical regions.

Placebo Response and Practice Effects in Schizophrenia Cognition Trials.

Importance: Patients' previous experience with performance-based cognitive tests in clinical trials for cognitive impairment associated with schizophrenia can create practice-related improvements. Placebo-controlled trials for cognitive impairment associated with schizophrenia are at risk for these practice effects, which can be difficult to distinguish from placebo effects.

Objectives: To conduct a systematic evaluation of the magnitude of practice effects on the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB) in cognitive impairment associated with schizophrenia and to examine which demographic, clinical, and cognitive characteristics were associated with improvement in placebo conditions.

Psychometric characteristics of the MATRICS Consensus Cognitive Battery in a large pooled cohort of stable schizophrenia patients.

The MATRICS Consensus Cognitive Battery (MCCB) was developed to assess cognitive treatment effects in schizophrenia clinical trials, and is considered the FDA gold standard outcome measure for that purpose. The aim of the present study was to establish pre-treatment psychometric characteristics of the MCCB in a large pooled sample. The dataset included 2616 stable schizophrenia patients enrolled in 15 different clinical trials between 2007 and 2016 within the United States (94%) and Canada (6%).

Views of a good life and allostatic load: Physiological correlates of theories of a good life depend on the socioeconomic context.

This research examines the relationship between one's theory of a good life and allostatic load, a marker of cumulative biological risk, and how this relationship differs by socioeconomic status. Among adults with a bachelor's degree or higher, those who saw individual characteristics (e.g.

Validation of the tablet-administered Brief Assessment of Cognition (BAC App).

Computerized tests benefit from automated scoring procedures and standardized administration instructions. These methods can reduce the potential for rater error. However, especially in patients with severe mental illnesses, the equivalency of traditional and tablet-based tests cannot be assumed.

Development of a virtual reality assessment of everyday living skills.

Cognitive impairments affect the majority of patients with schizophrenia and these impairments predict poor long term psychosocial outcomes.  Treatment studies aimed at cognitive impairment in patients with schizophrenia not only require demonstration of improvements on cognitive tests, but also evidence that any cognitive changes lead to clinically meaningful improvements.  Measures of "functional capacity" index the extent to which individuals have the potential to perform skills required for real world functioning.

Memory distortion in Alzheimer's disease: deficient monitoring of short- and long-term memory.

Objective: This study measured distortions of memory during short-term memory (STM) and long-term memory (LTM) versions of a semantically associated word list learning paradigm. Performance of patients with mild-to-moderate Alzheimer's disease (AD; MMSE ≥16) was compared with performance of age-matched, healthy older adult participants.

Method: In a STM version of the Deese-Roediger-McDermott (DRM) task, participants viewed four-word lists and were prompted for recall after a brief interval.

When less is heard than meets the ear: change deafness in a telephone conversation.

During a conversation, we hear the sound of the talker as well as the intended message. Traditional models of speech perception posit that acoustic details of a talker's voice are not encoded with the message whereas more recent models propose that talker identity is automatically encoded. When shadowing speech, listeners often fail to detect a change in talker identity.

Neural mechanisms of semantic interference and false recognition in short-term memory.

Decades of research using the Deese-Roediger-McDermott (DRM) paradigm have demonstrated that episodic memory is vulnerable to semantic distortion, and neuroimaging investigations of this phenomenon have shown dissociations between the neural mechanisms subserving true and false retrieval from long-term memory. Recently, false short-term memories have also been demonstrated, with false recognition of items related in meaning to memoranda encoded less than 5s earlier. Semantic interference is also evident in short-term memory, such that correct rejection of related lures is slowed relative to correct rejection of unrelated lures.

False memories seconds later: the rapid and compelling onset of illusory recognition.

Distortions of long-term memory (LTM) in the converging associates task are thought to arise from semantic associative processes and monitoring failures due to degraded verbatim and/or contextual memory. Sensory-based coding is traditionally considered more prevalent than meaning-based coding in short-term memory (STM), whereas the converse is true of LTM, leading to the expectation that false memory phenomena should be less robust in a canonical STM task. These expectations were violated in 2 experiments in which participants were shown lists of 4 semantically related words and were probed immediately following a filled 3- to 4-s retention interval or approximately 20 min later in a surprise recognition test.

False working memories? Semantic distortion in a mere 4 seconds.

False memories are well-established, episodic memory phenomena: Semantically related associates are confidently and erroneously remembered as studied items. We report four experiments yielding similar effects in a working memory paradigm. Four semantically related words were retained over a brief interval.
