The purpose of this project is to embed geriatric education throughout the undergraduate nursing curriculum. This multifaceted project integrates geriatrics theory and clinical content into 90% of the BSN curriculum. Florida State University College of Nursing is one of several educational partners with FSU's Live Oak Geriatric Education Center. At FSU, the BSN nursing curriculum is a two-year upper division program that integrates geriatric content throughout the nursing coursework. Beginning in the first semester, students learn skills using multiple scenarios in the college's simulation center. The geriatric content is presented through an unfolding case scenario that fits the skill development and theoretical content of the undergraduate nursing curriculum.
A range of ceramic multilayer nitride coatings, including NbxTiyN, NbxZryN, and MoxZryN, has been successfully deposited onto tool and die steels by closed field unbalanced magnetron sputter ion plating. The mechanical properties of the resulting coatings, including adhesion and hardness, have been evaluated by micro- and nano-indentation techniques, scratch testing etc. HPlast hardness up to 53 GPa has been achieved in the case of the NbxTiyN multilayers, 43 GPa for NbxZryN and 38 GPa for MoxZryN. The detailed microstructure of the coatings, including their respective nm-scale multilayer repeat distance, Λ, has been studied by advanced analytical techniques including high resolution transmission electron microscopy, ion backscattering (Rutherford, and non-Rutherford), and glancing angle X-ray diffraction, and focused ion beam machining and imaging. The coating properties are reviewed and correlated with the analytical data. Potential applications for, and some limitations of, the selected coatings are discussed.
Some studies suggest that there is antigenic and nucleic acid homology of one type of non-A, non-B hepatitis virus with hepatitis B viral (HBV) proteins and DNA. Using molecular hybridization under high and low stringency conditions with high specific activity 32P-HBV DNA as a probe, serum and liver samples from patients and nonhuman primates infected with non-A, non-B hepatitis were examined. Our results provide no evidence of significant homology between the DNA extracted from serum and liver of patients and nonhuman primates infected with one type of non-A, non-B hepatitis and HBV DNA.
Delta antigen (delta) is a transmissible agent requiring hepatitis B virus (HBV) for its replication. Antibody to delta (anti-delta) was present in nine of 71 (13%) British HBV carriers: six were intravenous drug abusers and two were haemophiliacs. Anti-delta was negative in 30 HBsAg positive homosexuals. Cirrhosis was common in patients with anti-delta and those with anti-delta positive cirrhosis were significantly younger than those with anti-delta negative cirrhosis. In British HBV carriers delta infection is associated with intravenous drug abuse and haemophilia and perhaps a more rapid progression of chronic liver disease.
The aetiology of acute viral hepatitis in 172 patients admitted to an infectious diseases hospital in North London was: hepatitis A in 88 (51%), hepatitis B in 58 (34%), Epstein-Barr (EB) virus in four (2%) and non-A, non-B in 22 (13%). NANB hepatitis was a milder disease than that associated with the other viruses. It predominantly occurred in young men (77%). In half of the cases there was evidence of parenteral transmission. It was not transmitted by sexual contact.
An antigen/antibody system associated with one form of parenterally transmitted non-A, non-B (NANB) hepatitis has been identified by solid-phase radioimmunoassay (RIA). The antigen is found in 3% of normal subjects and in increased frequency in patients with haemophilia, renal homograft recipients, homosexual men, prostitutes, drug addicts, and patients with chronic hepatitis B virus (HBV) infection. The antigen was found in normal frequency in patients with acute hepatitis A and B, sporadic NANB hepatitis (nondrug addicts), autoimmune and alcohol-induced chronic liver disease, and primary biliary cirrhosis.
Liver biopsies from 17 patients with serologically established hepatitis A were examined by light microscopy. Biopsies were taken from 2 to 27 weeks after onset of symptoms. All showed acute hepatitis, usually with centrilobular lesions but also commonly with a striking portal and periportal inflammatory reaction, resembling that seen in chronic active hepatitis. The infiltrate was rich in plasma cells. Centrilobular cholestasis was common and occasionally severe. Neither cholestasis nor the periportal lesion appeared to be related to patient age or to the timing of liver biopsy. All patients made a full recovery and none developed chronic liver disease. The histological changes differed from those reported in children and in chimpanzees in the presence of centrilobular lesions, but resembled them in that the latter two groups also had periportal lesions. These lesions may lead to a false impression of impending chronicity if the aetiology of the hepatitis is not known at the time of liver biopsy.
Ten cases are reported of short incubation (one to four weeks) non-A, non-B hepatitis occurring after infusion of various preparations of factor VIII concentrates into patients with coagulation disorders. Five patients were symptomatic and, in all, serum transaminase levels were increased for at least six months. These cases of chronic hepatitis exhibited none of the features of autoimmune chronic hepatitis: autoantibodies were negative and serum immunoglobulins were normal. Hepatic histology confirmed acute hepatitis in two cases biopsied early in the illness, and chronic active hepatitis (three) of chronic persistent hepatitis (two) in five cases studied later. Lobular inflammation was a prominent feature in all cases. Other features not commonly associated with type A or B hepatitis included fatty change and damaged bile ducts.
Liver biopsies from 12 patients with chronic Non‐A, Non‐B (NANB) hepatitis, 7 with hepatitis B surface antigen (HBsAg) positive chronic liver disease, 1 HBsAg positive normal carrier, and 4 patients with non‐viral liver disease, were examined by electron microscopy for cytoplasmic and nuclear changes. Aggregates of particles measuring 20–35 nm in diameter were noted in the nuclei of 8 of 12 patients with NANB chronic hepatitis, but not in the other groups. The tubular changes seen in the endoplasmic reticulum (ER) of chimpanzees with NANB hepatitis were not noted in biopsies from any of our patients.
Twelve serologically proven cases of non-A, non-B (NANB) hepatitis have been described. The clinical course was mild in 11 patients. One patient, however, presented in portal systemic encephalopathy and required steroid treatment. Nine of the 12 patients continued to exhibit raised transaminase (AST) activities six or more months after the onset of the acute hepatitis. In these immunoglobulin concentrations were normal and autoantibodies were not present in significant titre. Four patients had evidence of previous hepatitis B infection, suggesting that the route of transmission of NANB might be similar to that of hepatitis B virus. A further four patients gave a history which suggests a possible parenteral mode of transmission. Liver biopsies were carried out both in the acute (8 cases) and chronic (6 cases) phases of the disease. Histological findings in liver biopsies covered the whole spectrum of acute and chronic hepatitis and 1 patient had cirrhosis. One notable feature in these biopsies was the presence of fatty changes.
