Behandling av alkohol- och narkotikaproblem : En evidensbaserad kunskapssammanställning
- 2001
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Utvärderingens syfteMissbruk och beroende av alkohol är ett av de största folkhälsoproblemen. Narkotikamissbruk är mindre vanligt men har stora medicinska konsekvenser för de berörda. De sociala och juridiska aspekterna är betydande. En kritisk genomgång av litteraturen vad avser behandling av abstinens, protraherad abstinens, behandling i syfte att förhindra återfall, psykologiska och sociala behandlingar för att minska återfallsrisken, behandlingsprogram och institutionsvårdens roll, samt behandling av missbruk under graviditet. Dessutom en granskning av mini-intervention i primärvård och annan vård vars syfte är att minska konsumtionen hos högkonsumenter av alkohol. Nyligen gjorda meta-analyser inom området värderas och särskild vikt fästs vid interventioner som finns eller lätt kan introduceras i den svenska vårdorganisationen. Behandlingsprogram för patienter med samtidig annan psykisk störning värderas.Så kallat lågdosberoende av bensodiazepiner och andra lugnande medel eller sömnmedel behandlas inte. Inte heller belyses effekten av behandlingar vars primära mål är kroppsliga komplikationer av missbruket, och inte heller granskas metoder att minska tillgänglighet.TillvägagångssättStrukturerad översikt, kostnadsanalyser.Insamling av primärdataSystematisk sökning i relevanta databaser, litteraturlistor i påträffade studier samt i aktuella monografier. Ingen bakre tidsbegränsning och sökning i databaser till och med februari 1999.Utgångspunkt för urval av dataHuvudsakligen randomiserade, kontrollerade, dubbelblinda studier, samt metaanalyser som baseras på sådana studier. Vad gäller långtidsförlopp och ekonomiska analyser även kohortstudier och andra naturalistiska studier.Genomgång av publikationenSamtliga studier värderas med hjälp av en i gruppen utarbetad, och med övriga psykiatriprojekt gemensam, kvalitetsmall. Alla centrala studier läses av minst två i gruppen.Färdiga manuskript värderas av styrelse, expertgrupp samt externa granskare.

Tidskriftsartikel (refereegranskat)abstract
- This article describes the applicability of multivariate projection techniques, such as principal-component analysis (PCA) and partial least-squares (PLS) projections to latent structures, to the large-volume high-density data structures obtained within genomics, proteomics, and metabonomics. PCA and PLS, and their extensions, derive their usefulness from their ability to analyze data with many, noisy, collinear, and even incomplete variables in both X and Y. Three examples are used as illustrations: the first example is a genomics data set and involves modeling of microarray data of cell cycle-regulated genes in the microorganism Saccharomyces cerevisiae. The second example contains NMR-metabonomics data, measured on urine samples of male rats treated with either of the drugs chloroquine or amiodarone. The third and last data set describes sequence-function classification studies in a set of G-protein-coupled receptors using hierarchical PCA.

Omsorgsbegreppet i förskolan : Olika infallsvinklar på ett begrepp och dess relation till en verksamhet. Rapport från nätverk för barnomsorgsforskning, Göteborg 20-21 novemberg 2000
- 2001
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport innehåller texter som presenterats vid en konferens arrangerad inom ramen för Nätverk för barnomsorgsforskningi . Syftet med konferensen var att lyfta upp begreppet omsorg, diskutera dess innebörd, rädda det från retorisk förflackning och samtidigt via dess koppling till verksamheter belysa ett vidare sammanhang. När bamforskning diskuteras har jag på senare tid funnit det väsentligt att peka på att den har en kapacitet att kasta ljus över centrala samhällsfrågor. Forskning om barn bör inte bara vara en forskning om en viss grupp i samhället. Den nyare bamdomsforskningen söker tillämpa ett bamperspektiv. Detta innebär att fenomen studeras såsom de framstår från barnens perspektiv och att inverkan av olika sociala reformer, politiska förändringar och produktion av varor på barns liv belyses. Det handlar alltså både om att söka efter barnens perspektiv och att söka efter konsekvenserna för barnen av olika samhälleliga förändringar. Nya fålt som t.ex. barndomshistoria, barndomssociologi och barndomsantropologi har uppstått och begreppet generation har införts för att markera vikten av att anlägga ett generationsperspektiv på frågor som vanligtvis grupperats på annat sätt.

- Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy individuals. Sera from 36 patients with primary sclerosing cholangitis (PSC), 21 with primary biliary cirrhosis, 19 with autoimmune chronic hepatitis and 80 blood donors were analysed by immunoblot, using cell-surface proteins from Helicobacter pullorum, Helicobacter bilis and Helicobacter hepaticus as antigens. Prior to testing, sera were cross-absorbed with a whole-cell lysate of Helicobacter pylori. Antibody reactivity to various proteins of these three Helicobacter species was measured by densitometric scanning and results were processed by computer software to estimate antigenic specificity. Results were also compared with antibody response to H. pylori. For H. pullorum, reactivity to at least two of the proteins with molecular masses of 48, 45, 37, 20 and 16 kDa, for H. hepaticus, reactivity to the 76, 30 and 21 kDa proteins and for H. bilis, reactivity to the 22 and 20 kDa proteins, seemed to have high specificity. Positive immunoblot results with sera from patients with PSC to antigens of H. pullorum, H. bilis and H. hepaticus were found in 38, 22 and 25 of cases, respectively, and from patients with other autoimmune liver diseases, in 30, 22 and 22 of cases, respectively. Prevalence of serum antibodies to non-gastric Helicobacter species was significantly higher in patients with autoimmune chronic liver diseases than in healthy blood donors (P < 0.001). Increased antibody levels to enterohepatic Helicobacter species raise questions concerning an infectious role of these emerging bacterial pathogens in human autoimmune liver diseases.

- BACKGROUND: Bile tolerant helicobacter species such as H hepaticus and H bilis have frequently been reported to cause hepatitis in mice and other rodents. AIMS: To investigate the possible pathogenic role of these and other helicobacter species in chronic liver disease in humans. METHODS: Serum samples from 144 patients with various chronic liver diseases, 30 patients with primary sclerosing cholangitis (PSC), and 48 healthy blood donors were analysed for antibodies against H hepaticus murine strain CCUG 33637 and H pylori strain CCUG 17874. Cell surface proteins of H hepaticus were extracted by acid glycine buffer and used in an enzyme immunoassay (EIA) and immunoblot (IB). RESULTS: 56 of 144 (39%) patients with chronic liver diseases and six of 30 (20%) with PSC showed increased antibody concentrations in the H hepaticus EIA; in the H pylori EIA the numbers were 58% and 13% respectively. Compared with the healthy blood donors the antibody reactivity against the two helicobacter species was not increased (46% and 48% respectively). Patient serum samples retested by the H hepaticus EIA after absorption with sonicated H pylori cells remained positive in 12 of 37 (33%) serum samples. Distinct antibody reactivity to 55-65 kDa proteins was observed by H hepaticus IB, after the absorption step, and was considered specific for H hepaticus. These 12 serum samples were from patients with chronic alcoholic liver disease. CONCLUSIONS: Antibodies to H hepaticus, often cross reacting with H pylori, occur frequently in patients with chronic liver diseases, with no clear cut relation to specific diagnostic groups. The pathogenic significance of these findings is not known.

- In Stockholm, Sweden, the majority of pregnant women positive for hepatitis B surface antigen (HBsAg) are hepatitis Be antigen (HBeAg) negative. Newborns to HBeAg positive mothers receive vaccination and hepatitis B immunoglobulin (HBIg). Newborns to HBeAg negative mothers receive vaccine and HBIg only if the mothers have elevated ALT levels. The aim of this study was to retrospectively evaluate ALT levels as a surrogate marker for HBV DNA levels in HBeAg negative carrier mothers. Altogether 8947 pregnant women were screened for HBV markers from 1999 to 2001 at the Virology Department, Karolinska Hospital. Among mothers screened 192 tested positive for HBsAg (2.2%). 13 of these samples could not be retrieved. Of the remaining 179 sera, 8 (4%) tested positive for HBeAg and 171 (95.5%) were HBeAg negative. Among the HBeAg negative mothers, 9 had HBV DNA levels > 10(5) copies/ml, and of these 7 had normal ALT levels indicating low sensitivity of an elevated ALT level as a surrogate marker for high HBV DNA level. Furthermore, no correlation was found between ALT and HBV DNA levels. Hence, it is concluded that the use of ALT as a surrogate marker for high viral replication in HBeAg negative mothers could be questioned.

- Background-Accumulation and oxidation of LDL are believed to be important initiating factors in atherosclerosis. Oxidized LDL is recognized by the immune system, and animal studies have suggested that these immune responses have a protective effect against atherosclerosis. Aldehyde-modified peptide sequences in apolipoprotein B-100 (apoB-100) are major targets for these immune responses. Methods and Results-Human IgG1 antibodies against 2 malondialdehyde (MDA)-modified apoB-100 peptide sequences were produced through screening of a single-chain antibody-fragment library and subsequent cloning into a pcDNA3 vector. Three weekly doses of these antibodies were injected into male apoE(-/-) mice. Phosphate-buffered saline and human IgG1 antibodies against fluorescein isothiocyanate were used as controls. One of the IgG1 antibodies significantly and dose-dependently reduced the extent of atherosclerosis as well as the plaque content of oxidized LDL epitopes and macrophages. In cell culture studies, human monocytes were incubated with native LDL or oxidized LDL, in the presence of antibodies. The same antibody induced an increase in monocyte binding and uptake of oxidized LDL. Conclusions-These findings suggest that antibodies are important mediators of atheroprotective immune responses directed to oxidized LDL. Thus, passive immunization against MDA-modified apoB-100 peptide sequences may represent a novel therapeutic approach for prevention and treatment of cardiovascular disease.
