Swallowing Apnea Duration

The effects of age, gender, bolus volume, and trial on swallowing apnea duration (SAD) and swallow/respiratory phase relationships were examined. Sixty adults, comprised of ten males and ten females in each of three age groups (i.e., 20 to 39, 40 to 59, and 60 to 83 years), participated. SAD was assessed via nasal airflow during saliva swallows and 10, 15, 20, 25 ml bolus volumes across three trials. Results revealed SAD is consistent across trial (p > .05). Significant main effects of age, gender and bolus volume were found (p .05). Key words: Normal Swallowing - Respiration - Apnea - Deglutition - Duratio

Rank 3 permutation characters and maximal subgroups

In this paper we classify all maximal subgroups M of a nearly simple primitive rank 3 group G of type L=Omega_{2m+1}(3), m > 3; acting on an L-orbit E of non-singular points of the natural module for L such that 1_P^G <=1_M^G where P is a stabilizer of a point in E. This result has an application to the study of minimal genera of algebraic curves which admit group actions.Comment: 41 pages, to appear in Forum Mathematicu

The structure of blocks with a Klein four defect group

We prove Erdmann’s conjecture [16] stating that every block with a Klein four defect group has a simple module with trivial source, and deduce from this that Puig’s finiteness conjecture holds for source algebras of blocks with a Klein four defect group. The proof uses the classification of finite simple groups

On two theorems for flat, affine group schemes over a discrete valuation ring

Evaluation of an Activated Patient Diabetes Education Newsletter

This study evaluated a monthly; activated patient newsletter sent to over 7000 patients in Michigan with diabetes. The newsletter provided concise and action-oriented information about diabetes care. Patients who had signed up to receive the newsletter during the first 4 months of the project (1863) were surveyed to determine how many patients found the newsletter helpful; 80% (1498) of the patients replied. Patients who found the newsletter most helpful were older, had lower incomes, and reported more corrtplications, less understanding of diabetes, and being in poorer overall health. They also were more likely to have non-insulin-dependent diabetes mellitus (NIDDM) than insulin-dependent diabetes mellitus (IDDM). We concluded that the activated patient newsletter is a useful public health/patient education intervention for persons with diabetes. Such a newsletter should be part of a coordinated system of ongoing patient care, education, screening, and social and psychological support.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68904/2/10.1177_014572179402000106.pd

Patient Knowledge Compared With National Guidelines for Diabetes Care

Data collected on a randomly selected group of 428 patients with insulin-dependent and noninsulin-dependent diabetes from 61 physician practices in eight Michigan communities were compared with national standards for diabetes patient knowledge. Comparisons were performed using a standardized Diabetes Knowledge Test (DKT) and selected items from the Diabetes Education Profile (DEP). Patient performance on these instruments was compared with corresponding items in the Ambulatory Care Facilities section of the Guide lines for Diabetes Care published by the American Diabetes Associ ation and the American Associ ation of Diabetes Educators. In general, insulin-dependent persons scored higher than noninsulin-dependent persons. Those taking insulin (whether insulin-dependent or not) scored higher than noninsulin-dependent persons whose regimen did not include insulin. The findings emphasize the need to subdivide any analysis of clinical diabetes or diabetes education into groups based on insulin use or nonuse.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69139/2/10.1177_014572178801400312.pd

The Diabetes Education Experience of Randomly Selected Patients Under the Care of Community Physicians

The purpose of this study was to describe the diabetes education and nutritional counseling received by patients under the active care of community physicians. The study population consisted of 440 patients with diabetes from the practices of 68 primary care physicians in eight Michigan communities. Fifty-eight percent of the sample reported having received diabetes education, and the mean number of years since the most recent education was 4.15 years. Sixty-six percent reported having seen a dietitian. Patients who had received diabetes education scored higher on a basic diabetes knowledge test (70% correct vs 60%) than patients who had not received diabetes education. From 1981 to 1991, a decline was observed in the percentage of patients who reported having received diabetes education (70% to 58%). Although patient education is an integral part of comprehensive diabetes care, too few patients are receiving it. Furthermore, diabetes education often results in less-than-optimal levels of knowledge. The situation has deteriorated over the past 10 years, and patients who are not on insulin typically are the least well served.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68590/2/10.1177_014572179402000506.pd

Ancient Yersinia pestis and Salmonella enterica genomes from Bronze Age Crete

During the late 3rd millennium BCE, the Eastern Mediterranean and Near East witnessed societal changes in many regions, which are usually explained with a combination of social and climatic factors.1, 2, 3, 4 However, recent archaeogenetic research forces us to rethink models regarding the role of infectious diseases in past societal trajectories.5 The plague bacterium Yersinia pestis, which was involved in some of the most destructive historical pandemics,5, 6, 7, 8 circulated across Eurasia at least from the onset of the 3rd millennium BCE,9, 10, 11, 12, 13 but the challenging preservation of ancient DNA in warmer climates has restricted the identification of Y. pestis from this period to temperate climatic regions. As such, evidence from culturally prominent regions such as the Eastern Mediterranean is currently lacking. Here, we present genetic evidence for the presence of Y. pestis and Salmonella enterica, the causative agent of typhoid/enteric fever, from this period of transformation in Crete, detected at the cave site Hagios Charalambos. We reconstructed one Y. pestis genome that forms part of a now-extinct lineage of Y. pestis strains from the Late Neolithic and Bronze Age that were likely not yet adapted for transmission via fleas. Furthermore, we reconstructed two ancient S. enterica genomes from the Para C lineage, which cluster with contemporary strains that were likely not yet fully host adapted to humans. The occurrence of these two virulent pathogens at the end of the Early Minoan period in Crete emphasizes the necessity to re-introduce infectious diseases as an additional factor possibly contributing to the transformation of early complex societies in the Aegean and beyond.Results and discussion STAR★Method
