Health literacy is a partial mediator of racial disparities in cognitive decline. These results indicate the need to develop interventions to mitigate cognitive decline that individuals with low heath literacy can use and to modify the healthcare environment to better accommodate this population.

Digital subtraction angiography (DSA) allows quantitative analysis of ventricular function via densitometric and parametric imaging techniques. However, DSA is limited by the artifacts in temporal subtraction images that result from patient and cardiac motion. Dual-energy subtraction imaging is insensitive to motion. This study evaluated the initial application of dual-energy subtraction in cardiac patients. The image quality of dual-energy subtraction left ventriculograms obtained from a pulmonary artery injection of contrast was assessed in 13 patients, ranging in weight from 54 to 100 kg. The dual-energy images were compared with left ventricular images obtained using standard left ventricular injection cine angiography. End-systolic and end-diastolic ventricular volumes calculated from the cine (C) and dual-energy (DE) images using the Area-Length method were compared. The resulting regression line was DE = 0.98 C+ 7.0 ml, and the r value was 0.987. Dual-energy subtraction provided good left ventricular visualization, free from misregistration artifacts, even during patient motion.

In larval lamprey, movements and muscle activity during swimming and burrowing behaviors were compared. Burrowing consisted of two components: an initial component in which the head was driven into the burrowing medium; and a final component in which the animal pulled the rest of its body into the burrowing medium. The initial component of burrowing was characterized by large undulatory movements and rhythmic muscle burst activity that were similar in form to those during fast swimming, but more intense. During the initial component of burrrowing, burst durations, burst amplitudes, and burst proportions of motor activity were larger than those during swimming, while cycle time was slightly shorter than during swimming. Intersegmental phase lags and right-left phase values were similar for swimming and initial burrowing. The final component of burrowing was characterized by sharp, long-duration flexures on one side of the body, sometimes followed by similar flexures on the other side. Each flexure was produced by long-duration, large-amplitude muscle burst activity on the same side of the body or several shorter sequential bursts with slightly smaller amplitudes. During the final component of burrowing, burst durations and burst amplitudes of motor activity were much larger than those during swimming or during the initial component of burrowing. It is suggested that the motor patterns for swimming and the initial component of burrowing are produced by a common spinal locomotor network. The final component of burrowing may use some of the same neurons in the spinal locomotor networks, but the networks are probably configured differently than the situation during swimming.

Background The occurrence of adverse drug reactions with chemotherapy among cancer patients is a well-documented phenomenon. However, the understanding of contributoring factors and their influence on the severity of adverse drug reactions is incomplete without the psychosocial factors affecting them. Objective The present study was done to understand if factors like Health literacy and cognition levels have an association with the severity of adverse drug reactions of cancer chemotherapy. Setting This study was done in the Department of Medical Oncology in a tertiary care hospital in India. Method Two hundred and twenty-four patients meeting the study inclusion and exclusion criteria took part in the study. Details of adverse drug reactions were collected as per the central drugs standard control organization format and severity of adverse drug reactions assessed with National Cancer Institute common terminology criteria of adverse events, version 5.0. Health Literacy and Cognition Levels of patients were assessed using standardized questionnaires, i.e., Short test of functional health literacy in adults and short portable mental status questionnaire, respectively. Data were anonymized and analyzed using Statistical Package for Social Sciences version 16.0 software. Pearson’s Chi square test (p value ≤ 0.05 was considered statistically significant) was used to study the associations. Main outcome measure The associations of Health Literacy and Cognition Levels with the severity of adverse drug reactions. Result We found that both Health Literacy and Cognition Levels had a statistically significant association with Grade 3 and above adverse drug reactions in cancer patients receiving chemotherapy. Conclusion An initial assessment of Health Literacy and Cognition Levels in cancer patients by cancer care providers can help identify patients at high risk of developing severe adverse drug reactions. Interventional measures for improving Health Literacy by healthcare providers can help reduce the overall burden of disease on the patient due to adverse drug reactions.

Success in the management of palatal defects depends on accurate appreciation of the size and functional extent of each defect, careful patient selection, and specific attention to each patient's goals.
