The faculty work plan and appraisal: its potential for faculty role development

This exploratory study was designed to begin analysis on the "Faculty Work Plan" and its potential for faculty role development in a university setting. The specific goals were: (1) to identify the degree of congruence between faculty work plans and the school goals; and (2) to determine the relationship between faculty work plan/school goal congruence, faculty productivity, potency, and job satisfaction. The sample was composed of 26 respondents, 26 to 50 years old, from a pool of 48 full-time faculty members affiliated with a school of nursing in a university setting. Likert-type rating scores were used to measure Faculty Work Plan-School Goal Congruence (FWP-SG), job satisfaction, productivity, and potency. Data analyses were focused on frequency distribution, group means, and Pearson Correlation Coefficients on selected pairs of variables. Interesting findings were revealed. A strong relationship was found between FWP-SG congruence and faculty productivity (r = .85; p = .000) and potency (r = .84; p = .000). Several recommendations were suggested.     

Group A meningococcal disease in the U.S. Pacific Northwest: epidemiology, clinical features, and effect of a vaccination control program

In 1975 an outbreak of group A meningococcal disease began in Seattle, Washington, and cases subsequently were recognized throughout the Pacific Northwest. Nearly one-half of the affected persons were Native Americans; two-thirds were alcohol abusers and/or habitués of skid road communities. In Seattle, group A meningococci colonized asymptomatic persons only if these individuals had contact with skid road (P = .006). The epidemic strain may have spread from American Indians in Manitoba, Canada. Traditional migration routes connect the two populations; asymptomatic American Indians on reservations in Washington carried group A meningococci. Vaccination programs were undertaken in four cities but only after cases occurred. In Seattle, vaccination reached 80% of the target population and was associated with a significant decrease in incidence of the disease, but cases recurred after the program ended. The social habits of skid road communities, combined with the "case-triggering" approach to, and premature termination of, vaccination programs, may have resulted in 56% of regional cases occurring after the start of the vaccination program in Seattle.     

Anteroposterior lip positions of the most-favored Japanese facial profiles.

INTRODUCTION: Soft tissue analysis is a basic tool in planning orthodontic treatment. However, the components of a well-balanced Japanese facial profile have not yet been established. The purpose of this study was to assess the most-favored or most well-balanced profile from a series of facial silhouettes with varying anteroposterior lip positions by a group of Japanese orthodontists and a group of young adult Japanese dental students. METHODS: Average female and male profiles were constructed from the profiles of 30 Japanese men and women with normal occlusions. The lips in each average profile were protruded or retruded in 1-mm increments, and the 13 images were arranged with the average profile in the center. Forty two orthodontists and 42 dental students were asked to select the 3 most-favored, well-balanced profiles for each sex and rank them in order of preference. RESULTS: Both the orthodontists and the students preferred a profile with slightly retruded lips. The dental students favored a more retruded lip position for women. The least-favored profile was the most protrusive. CONCLUSIONS: These findings suggest that Japanese orthodontists and young adults prefer a retruded profile, even though Japanese profiles have historically been characterized by more convex facial features.     

Immunologic status of hemophilia patients treated with cryoprecipitate or lyophilized concentrate

We evaluated 37 patients with moderate or severe hemophilia A and six patients with severe factor IX deficiency for clinical or laboratory evidence of immune abnormalities. Patients were assigned to one of four groups according to the type of clotting factor replacement. Twenty patients had received only cryoprecipitate during the two years preceding the evaluation (group I); 11 additional patients were treated predominantly with cryoprecipitate but had also received up to nine bottles of factor VIII concentrate (group II); six patients received factor VIII concentrate (group III); six patients received factor IX concentrate (group IV). There was no clinical or laboratory evidence of immunodeficiency among the 43 patients. The mean absolute number of Th cells was normal in all patient groups, but the mean absolute number of Ts cells was increased compared with controls, both in patients treated with cryoprecipitate and in patients treated with factor VIII or factor IX concentrate. There was no correlation between the Th/Ts ratio and patient age, alanine aminotransferase level, hepatitis serology, in vitro lymphocyte function, or amount of clotting factor administered. Our observations demonstrate that the volunteer or commercial origin of clotting factor replacement cannot fully explain the alterations in lymphocyte subset distribution previously described in patients with hemophilia A.     

Anti-inflammatory prednisolone derivatives inhibit collagen synthesis and pro-α1 (I) collagen promoter activity in rat skin fibroblasts

Inhibition of wound healing by anti-inflammatory steroids is associated with decreased collagen synthesis. Methyl-20-dihydroprednisolonate has been previously reported to be anti-inflammatory without inhibiting collagen synthesis in skin when given either subcutaneously or intraperitoneally. The data we now report show that this prednisolone derivative, as well as two 9alpha fluorinated derivatives inhibit both collagen synthesis and pro-alpha(1) (I) collagen gene promoter activity in rat skin fibroblasts. Our data suggest that metabolism, absorption, or distribution of these corticosteroids results in their inability to inhibit collagen synthesis in vivo. In addition our data indicate that fluorination in the 9alpha position of the adrenal steroid nucleus is not required for the inhibition of collagen synthesis by methyl-20-dihydroprednisolonate.     

Studies of the intercellular matrix of growth plates from dwarf and homozygous nonaffected alaskan malamutes: Collagen and hexosamine

Summary This study was performed to compare the extractability of dwarf growth plate collagen and hexosamine with that of homozygous nonaffected Malamutes and to measure the activity of three of the enzymes involved in the post-translational modifications of the collagen molecule. No significant differences were found in the activity of prolyl hydroxylase or lysyl oxidase in the dwarf growth plates. Lysyl hydroxylase activity in the dwarf was decreased to 22% and 33% that of the activity present in the homozygous nonaffected growth plates. Amino acid analysis of the collagen isolated from dwarf growth plates failed to reveal any decrease in hydroxylysine content. Growth plates were extracted with either 1 M sodium chloride or 4 M guanidine hydrochloride. The extracts were applied to a DEAE-cellulose column. Amino acid analyses of the material which did not bind to DEAE revealed a slight decrease in the amount of guanidine-extractable hydroxyproline in the dwarf but a 60-fold increase in the amount of salt-extractable hydroxyproline in the dwarf growth plates. Material which eluted with 1 M sodium chloride was analyzed for hexosamine. There was a 10-fold increase in the amount of salt-extractable hexosamine present in the dwarf growth plates, whereas no significant differences were observed in the guanidine-extracted material. Hexosamine analysis of the growth plates revealed a significant increase in the total amount of hexosamine present in the dwarf growth plates. SDS-polyacrylamide gels of the material which did not bind to DEAE as well as the pepsin digested, 0.9M sodium chloride precipitated collagen demonstrated the presence of only type II collagen.     

Hemostasis in massively transfused trauma patients.

Twenty-seven patients requiring massive transfusions were studied prospectively to determine whether administration of stored, modified whole blood induced a primary disorder of hemostasis evidenced by generalized microvascular oozing. Platelet counts fell in proportion to the number of units of blood transfused. In contrast, the levels of factors V and VIII correlated poorly with the units of blood transfused, 85% of the total variation in the levels being due to influences other than transfused blood. Levels of all other clotting factors were unrelated to the number of units of blood given. Eight patients developed abnormal bleeding. The cause appeared to be dilutional thrombocytopenia in five patients, and DIC in three. In six of the eight, bleeding was controlled with platelet concentrates alone. Two patients were given cryoprecipitate also. The most useful laboratory test for predicting abnormal bleeding was the platelet count. Fibrinogen levels should be followed as an aid in the diagnosis of DIC. The BT, PT, and PTT were not helpful in assessing the cause of bleeding, unless they were greater than 1.5 times the control value. We recommend that any patient receiving massive transfusions who develops diffuse microvascular bleeding be given platelet concentrates. Platelet counts as high as 100,000 may be required to control bleeding from surgical wounds. It is not necessary to supplement transfusions of stored, modified whole blood with fresh blood or fresh frozen plasma.
