BACKGROUND: Pain is a common symptom in cancer patients. Acupuncture is a suggested treatment for a wide range of clinical conditions, usually for its beneficial effects on pain control. Si guan xue (the four points) have been widely used in clinical practice, and has shown that it is highly effective, effective in obtaining qi, shows strong acupuncture stimulation, and is simple to manipulate and safe to use. Therefore, the aim of this study is to test the protocol and safety of acupuncture at the si guan xue in the management of cancer pain...

The current study explored the persistence of event model organizations and how this influences the experience of interference during retrieval. People in this study memorized lists of sentences about objects in locations, such as "The potted palm is in the hotel." Previous work has shown that such information can either be stored in separate event models, thereby producing retrieval interference, or integrated into common event models, thereby eliminating retrieval interference. Unlike prior studies, the current work explored the impact of forgetting up to 2 weeks later on this pattern of performance...

OBJECTIVE: The Timeline Follow-back (TLFB) questionnaire has become a pre-eminent tool in substance use and human immunodeficiency virus (HIV) risk research, allowing researchers to assess fine-grained changes in risk behavior over long periods. However, data on accuracy of recall over long (12-month) periods are sparse, especially combined data on HIV risk and substance use from post-treatment samples. Studies on the development of substance use and HIV risk stand to benefit from data on the accurate recall of such behavior over longer retroactive spans of time...

Coronary artery disease (CAD) is the leading cause of death in the United States. The World Bank and the World Health Organization predict that depression and coronary heart disease will be the largest causes of global health burden and disability by the year 2020. Studies have demonstrated that patients with CAD experience depression at a higher rate than the general population. Because of this connection, it is critical to recognize depression and manage depression effectively for people with CAD. Studies have also provided evidence that identifying and treating depression in patients early after a myocardial infarction improve clinical outcomes...

BACKGROUND: Evidence suggests that exercise training for hemodialysis patients positively improves morbidity and mortality outcomes, yet exercise programs remain rare and are not systematically incorporated into care. We developed a research-based film, Fit for Dialysis, designed to introduce, motivate, and sustain exercise for wellness amongst older hemodialysis patients, and exercise counseling and support by nephrologists, nurses, and family caregivers. The objective of this clinical trial is to determine whether and in what ways Fit for Dialysis improves outcomes and influences knowledge/attitudes regarding the importance of exercise for wellness in the context of end-stage renal disease...

Critical issues about scientific reproducibility have been raised about biomedical research, including the reliability of data and analyses within a given study. The case example in this article examined a reproducibility issue pertaining to the use of administrative data systems for evaluation of child maltreatment (CM) prevention, making use of a prevention study conducted over a decade ago that provided a unique opportunity. The place-randomization study, which randomized counties to condition, found that community-wide implementation of a parenting and family support intervention produced positive impact on county-wide rates for substantiated CM cases and out-of-home placements, documented through a state information system...

In two experiments, we explored the effects of noticing and remembering change in the misinformation paradigm. People watched slide shows, read narratives containing misinformation about the events depicted in the slide shows, and took a recognition test on which they reported whether any details had changed between the slides and the narratives. As expected, we found a strong misinformation effect overall. In some cases, however, misinformation led to improved recognition, which is opposite the usual finding...

Past research using handedness as a proxy for functional access to the right hemisphere demonstrates that individuals who are mixed/inconsistently handed outperform strong/consistently handed individuals when performing episodic recall tasks. However, research has generally been restricted to stimuli presented in a list format. In the present paper, we present two studies in which participants were presented with paragraph-level material and then asked to recall material from the passages. The first study was based on a classic study looking at retroactive interference with prose materials...

It has recently been found that episodic memory displays analogues of the well-known disjunction and conjunction fallacies of probability judgement. The aim of the present research was, for the first time, to study these memory fallacies together under the same conditions, and test theoretical predictions about the reasons for each. The focus was on predictions about the influence of semantic gist, target versus context recollection, and proactive versus retroactive interference. Disjunction and conjunction fallacies increased in conditions in which subjects were able to form semantic connections among list words...

OBJECTIVE: Auditory Verbal Learning Test (AVLT) is frequently used in neuropsychology literature to comprehensively assess the memory. The test measures verbal learning as immediate and delayed free recall, recognition, and retroactive and proactive interference. Adaptation of AVLT to the Turkish society has been completed, whereas research and development studies are still underway. The purpose of the present study is to investigate the construct validity of the test in order to contribute to the research and development process...

BACKGROUND: Audit and feedback (A&F) is a strategy that has been used in various disciplines for performance and quality improvement. There is limited research regarding medical professionals' acceptance of clinical-performance feedback and whether feedback impacts clinical practice. The objectives of our research were to (1) investigate aspects of A&F that impact physicians' acceptance of performance feedback; (2) determine actions physicians take when receiving feedback; and (3) determine if feedback impacts physicians' patient-management behavior...

OBJECTIVE: To examine the utility of a novel "cognitive stress test" to detect subtle cognitive impairments and amyloid load within the brains of neuropsychologically normal community-dwelling elders. METHODS: Participants diagnosed as cognitively normal (CN), subjective memory impairment (SMI), mild cognitive impairment (MCI), and preclinical mild cognitive impairment (PreMCI) were administered the Loewenstein-Acevedo Scale for Semantic Interference and Learning (LASSI-L), a sensitive test of proactive semantic interference (PSI), retroactive semantic interference, and, uniquely, the ability to recover from the effects of PSI...

Youth with sexually problematic behaviors are impacted by the reciprocal interplay between individual characteristics and the key social and ecological systems in which they are embedded. The paucity of research on protective factors mitigating risks within various socioecological systems is of concern, as the school is one such system that has been overlooked. This study retroactively investigated probation files among youth who were adjudicated of a sexual crime (N = 85) to determine how school-level variables are associated with treatment completion...

Recent research findings suggest neuro-modulation of tumors. Finding new modifiable prognostic factors paves the way for additional treatments, which is crucial in advanced cancer, particularly pancreatic cancer. This study examined the relationship between vagal nerve activity, indexed by heart rate variability (HRV), and overall survival (OS) in patients (N=272) with advanced pancreatic cancer. A "historical prospective" design was employed, where vagal activity and other confounders were retroactively obtained from medical charts at diagnosis, and subsequent OS was examined...

BACKGROUND: Epidemiological research on post-stroke affective disorders has been mainly focusing on post-stroke depression (PSD). In contrast, research on post-stroke anxiety (PSA) is in its early stages. The present study proposes a broad picture on post-stroke affective disorders, including PSD and PSA in German stroke in-patients during rehabilitation. In addition, we investigated whether lifetime affective disorders predict the emergence of PSD and PSA. METHODS: 289 stroke patients were assessed in the early weeks following stroke for a range of mood and anxiety disorders by means of the Structured Clinical Interview relying on the Diagnostic and Statistical Manual of Mental Disorders IV...

Early studies from psychology suggest that sleep facilitates memory retention by stopping ongoing retroactive interference caused by mental activity or external sensory stimuli. Neuroscience research with animal models, on the other hand, suggests that sleep facilitates retention by enhancing memory consolidation. Recently, in Drosophila, the ongoing activity of specific dopamine neurons was shown to regulate the forgetting of olfactory memories. Here, we show this ongoing dopaminergic activity is modulated with behavioral state, increasing robustly with locomotor activity and decreasing with rest...

Learning often affects future learning and memory for previously learned information by exerting either facilitation or interference effects. Several theoretical accounts of interference effects have been proposed, each making different developmental predictions. This research examines interference effects across development, with the goal of better understanding mechanisms of interference and of memory development. Preschool-aged children and adults participated in a 3-phased associative learning paradigm containing stimuli that were either unique or repeated across phases...

BACKGROUND: Functional magnetic resonance imaging (fMRI) time series are subject to corruption by many noise sources, especially physiological noise and motion. Researchers have developed many methods to reduce physiological noise, including RETROICOR, which retroactively removes cardiac and respiratory waveforms collected during the scan, and CompCor, which applies principal components analysis (PCA) to remove physiological noise components without any physiological monitoring during the scan...

BACKGROUND: Facial expressions of emotions represent classic stimuli for the study of social cognition. Developing virtual dynamic facial expressions of emotions, however, would open-up possibilities, both for fundamental and clinical research. For instance, virtual faces allow real-time Human-Computer retroactions between physiological measures and the virtual agent. OBJECTIVES: The goal of this study was to initially assess concomitants and construct validity of a newly developed set of virtual faces expressing six fundamental emotions (happiness, surprise, anger, sadness, fear, and disgust)...
