Wie effektiv sind systematische Rückmeldungen des Therapieverlaufs an den Therapeuten? Eine empirische Studie in einem stationär-verhaltenstherapeutischen Setting

Theoretischer Hintergrund: Die systematische Rückmeldung des Therapieverlaufs an den Therapeuten erwies sich in mehreren Studien an ambulant behandelten, überwiegend gering beeinträchtigten Patienten als effektives Mittel, um die Wirksamkeit psychotherapeutischer Behandlungen für potenziell problematische Patienten zu steigern. Fragestellung: Lassen sich diese Befunde auch in einem stationär-verhaltenstherapeutischen Setting replizieren und inwieweit sind sie wirklich auf misserfolgsgefährdete Patienten beschränkt? Methode: In einem randomisierten Gruppenvergleich (N = 118) erhielt die Hälfte der Therapeuten ein systematisches Feedback über den Therapieverlauf. Ergebnisse: Die Patienten in der Feedback-Bedingung verbesserten sich bei allen untersuchten Therapieerfolgsmaßen stärker als die Patienten der Kontrollgruppe. Schlussfolgerung: Ein systematisches Feedback des Therapieverlaufs an den Therapeuten führt zu einer Verbesserung der Effektivität stationär-verhaltenstherapeutischer Behandlungen. Zukünftige Forschung sollte nach Wegen suchen, die monetären und psychologischen Kosten von Feedbacksystemen zu reduzieren, um deren Einsatz in Settings der Routineversorgung zu erleichtern.

Får jämställdheten plats? En studie av översiktsplaneringens behandling av sociala kategorier

Syftet med den här studien är att undersöka hur jämställdhet har behandlats i förhållande till övriga sociala kategorier i översiktsplaneringen. Vidare är syftet att undersöka om detta skiljer sig åt mellan olika typer av kommuner och över tid. Studien bygger på en intersektionell ansats och urvalet bygger på tidigare teorier kring genuskontrakt där fem kommuner i varje genuskontraktstyp inkluderas. Kommunernas översiktsplaner, både aktuella och äldre, studeras genom att genomföra en kvantitativ textanalys där sociala kategoriers utrymme undersöks och en diskursanalys där beskrivningen av sociala kategorier studeras. Resultatet visar att tio sociala kategorier inkluderas i översiktsplaneringen. Jämställdhet har gått från att få näst minst utrymme i de äldre översiktsplanerna till att idag få näst mest utrymme jämfört med övriga sociala kategorier. Jämställdhet beskrivs på liknande sätt som barn, funktionshindrade och äldre att gynnas av en nära, funktionsblandad stad med fungerande kollektivtrafik. Vilket genuskontrakt en kommun har påverkar främst hur kommunerna beskriver jämställdhet, mångfald och äldre.

Effektiv lagerstyrning med AHP och tvådimensionell artikelklassificering : En fallstudie på Permobil AB, Timrå

Costs related to inventory are usually a significant amount of the company’s total assets. Despite this, companies in general don’t pay a lot of interest in it, even if the benefits from effective inventory are obvious when it comes to less tied up capital, increased customer satisfaction and better working environment. Permobil AB, Timrå is in an intense period when it comes to revenue and growth. The production unit is aiming for an increased output of 30 % in the next two years. To make this possible the company has to improve their way to distribute and handle material,The purpose of the study is to provide useful information and concrete proposals for action, so that the company can build a strategy for an effective and sustainable solution when it comes to inventory management. Alternative methods for making forecasts are suggested, in order to reach a more nuanced perception of different articles, and how they should be managed. Analytic Hierarchy Process (AHP) was used in order to give specially selected persons the chance to decide criteria for how the article should be valued. The criteria they agreed about were annual volume value, lead time, frequency rate and purchase price. The other method that was proposed was a two-dimensional model where annual volume value and frequency was the criteria that specified in which class an article should be placed. Both methods resulted in significant changes in comparison to the current solution. For the spare part inventory different forecast methods were tested and compared with the current solution. It turned out that the current forecast method performed worse than both moving average and exponential smoothing with trend. The small sample of ten random articles is not big enough to reject the current solution, but still the result is a reason enough, for the company to control the quality of the forecasts.

Dialektisk beteendeterapi i svensk öppenvård : en longitudinell effectiveness-studie

Borderline personlighetsstörning är en allvarlig psykiatrisk störning som leder till stor funktionsnedsättning för den drabbade, varpå vikten att erbjuda dessa patienter en effektiv och evidensbaserad behandling är stor. Föreliggande longitudinella effectiveness-studie undersökte om dialektisk beteendeterapi hade effekt på patienter med borderline personlighetsstörning och subklinisk emotionell instabilitet i svensk subspecialiserad öppenvård. Studien ämnade besvara om det fanns någon förändring för patientgruppen över tid gällande borderlinediagnos, borderlinesymptom, självskadebeteende, suicidförsök och komorbiditet, samt vilka prediktorer som predicerade behandlingsutfall. Sammanfattningsvis visade resultaten en minskning i borderlinediagnos, borderlinesymptom, suicidförsök, självskadebeteenden, samt komorbida diagnoser vid behandlingsavslut. Minskning i antal ångeststörningar under behandlingen visade sig vara en signifikant prediktor för minskning i BPS-symptom och ett större antal individualsessioner visade sig vara en signifikant prediktor för minskning i självskadebeteenden över tid. Resultatet tyder på att patientgruppen signifikant förbättrades i just denna kliniska kontext, efter att de genomgått dialektisk beteendeterapi. Potentiella förklaringar till resultatet diskuteras samt förslag på vidare forskning anges.

Vuxna ADHD patienters upplevelse av delaktighet och behov av sjuksköterskans stöd vid behandling inom öppenvårdspsykiatrin En kvalitativ intervjustudie

Bakgrund: Många vuxna med ADHD avbryter sin behandling av okända orsaker. Därför är det viktigt att undersöka hur vuxna med ADHD upplever sina möjligheter att vara delaktiga i behandlingen och på vilket sätt sjuksköterskan kan vara till stöd för dem. Syfte: Att beskriva vuxna ADHD patienters upplevelse av delaktighet och behov av sjuksköterskans stöd vid behandling inom öppenvårdspsykiatrin. Metod: Kvalitativ studie som baseras på åtta semistrukturerade intervjuer. Intervjumaterialet analyserades med innehållsanalys. Resultat: Många upplevde att de saknade information om diagnos och behandling och att de därför inte kunde vara med och påverka. Sjuksköterskan upplevdes vara lättare att nå än läkaren och kunde erbjuda tätare uppföljningar. Sjuksköterskan upplevdes också ha en samordnande funktion mellan olika yrkeskategorier. Att bli sedd som person och inte bli reducerad till en patient med ADHD var viktigt. Slutligen framkom betydelsen av att även involvera närstående i behandlingen. Slutsats: En del av sjuksköterskans arbete är att föra ut kunskap och information till patienterna på ett sätt som patienterna förstår utifrån varje persons specifika behov för att öka patienternas möjlighet till delaktighet. Specialistsjuksköterskan kan också utgöra ett stöd genom möjligheten att erbjuda tätare kontakt och mer uppföljning, samordning med andra yrkesgrupper och samhällsinstanser. Stöd kan också handla om att se människan bakom diagnosen.

Patienters erfarenheter vid behandling av svårläkta bensår : En litteraturstudie

Introduktion: I Sverige är svårläkta bensår ett utbrett problem som ofta kräver långvarig behandling. För att behandla bensår krävs att sjuksköterskan och patient samarbetar. Syfte: Syftet med litteraturstudien var att belysa erfarenheter hos patienter som lever med behandling av svårläkta sår. Metod: Metoden som använts är en litteraturstudie vilken baseras på en sammanställning av befintlig forskning. Sökningar efter vetenskapliga artiklar gjordes i databaserna Cinahl och PubMed och resulterade i 11 artiklar vilka granskats utifrån Polit och Becks kvalitetsgranskningsmallar. Alla artiklars resultat lästes igenom flera gånger och viktiga delar ströks under och klipptes ut. De urklippta delarna skapade tre kategorier med vardera två underkategorier. Resultat: I litteraturstudien framkom att patienter ofta fokuserade mycket på hur relationen till sjuksköterskan såg ut.  Det framkom att smärta var det patienterna oftast tog upp angående sitt fysiska mående och att de upplevde att de sällan fick tillräckligt gehör från sjuksköterskan angående sin smärta. Slutsats:  De flesta patienterna uttryckte negativa erfarenheter av hur själva sårbehandlingen kändes men att en god relation till sjuksköterskan var det som kändes mest värdefullt.

Molecular mechanisms of cancer predisposition in HNPCC/Lynch syndrome

Hereditary non-polyposis colorectal carcinoma (HNPCC; Lynch syndrome) is among the most common hereditary cancers in man and a model of cancers arising through deficient DNA mismatch repair (MMR). It is inherited in a dominant manner with predisposing germline mutations in the MMR genes, mainly MLH1, MSH2, MSH6 and PMS2. Both copies of the MMR gene need to be inactivated for cancer development. Since Lynch syndrome family members are born with one defective copy of one of the MMR genes in their germline, they only need to acquire a so called second hit to inactivate the MMR gene. Hence, they usually develop cancer at an early age. MMR gene inactivation leads to accumulation of mutations particularly in short repeat tracts, known as microsatellites, causing microsatellite instability (MSI). MSI is the hallmark of Lynch syndrome tumors, but is present in approximately 15% of sporadic tumors as well. There are several possible mechanisms of somatic inactivation (i.e. the second hit ) of MMR genes, for instance deletion of the wild-type copy, leading to loss of heterozygosity (LOH), methylation of promoter regions necessary for gene transcription, or mitotic recombination or gene conversion. In the Lynch syndrome tumors carrying germline mutations in the MMR gene, LOH was found to be the most frequent mechanism of somatic inactivation in the present study. We also studied MLH1/MSH2 deletion carriers and found that somatic mutations identical to the ones in the germline occurred frequently in colorectal cancers and were also present in extracolonic Lynch syndrome-associated tumors. Chromosome-specific marker analysis implied that gene conversion, rather than mitotic recombination or deletion of the respective gene locus accounted for wild-type inactivation. Lynch syndrome patients are predisposed to certain types of cancers, the most common ones being colorectal, endometrial and gastric cancer. Gastric cancer and uroepithelial tumors of bladder and ureter were observed to be true Lynch syndrome tumors with MMR deficiency as the driving force of tumorigenesis. Brain tumors and kidney carcinoma, on the other hand, were mostly MSS, implying the possibility of alternative routes of tumor development. These results present possible implications in clinical cancer surveillance. In about one-third of families suspected of Lynch syndrome, mutations in MMR genes are not found, and we therefore looked for alternative mechanisms of predisposition. According to our results, large genomic deletions, mainly in MSH2, and germline epimutations in MLH1, together explain a significant fraction of point mutation-negative families suspected of Lynch syndrome and are associated with characteristic clinical and family features. Our findings have important implications in the diagnosis and management of Lynch syndrome families.

Skogsbränslets elementära sammansättning med tanke på förbränningsprocessen och för näringsämnesförluster i ekosystemet

There are several reasons for increasing the usage of forest biomass for energy in Finland. Apart from the fact that forest biomass is a CO2 -neutral energy source, it is also a domestic resource distributed throughout the country. Usage of forest biomass in the form of logging residues decreases Finland’s dependence of energy import and increases both incomes and employment. Wood chips are mainly made from logging residues, which constitute 64 % of the raw material. A large-scale use of forest biomass requires heed also to the potential negative aspects. Forest bioenergy is used extensively, but its impacts on the forests soil nutrition and carbon balance has not been studied much. Nor have there been many studies on the heavy metal or chlorine content of logging residues. The goal of this study was to examine the content of carbon, macronutrients, heavy metals and other for the combustion harmful substances in Scots pine and Norway spruce wood chips, and to estimate the effect of harvesting of logging residues on the forests carbon and nutrient balance. Another goal was to examine the energy content of the clear cut remains. The Wood chips for this study were gathered from pine and spruce dominated clear cut sites in southern Finland, in the costal forests between Hankoo and Siuntio. The number of sample locations were 29, and the average area was 3,15 ha and the average timber volume 212,6 m3 ha -1. The average logged timber volume was for Scots pine timber 70 m3 ha -1 and for Norway spruce timber 124 m3 ha -1 and for deciduous timber (birch and alder) 18,5 m3 ha -1. The proportion of spruce in the logging residues and the stand-volume were relevant for how much nutrients were taken from the forest ecosystem when harvesting logging residues. In this study it was noted that the nutrient content of the logging residues clearly increased when the percentage of spruce in the timber volume increased. The S, K, Na and Cl -contents in the logging residues in this study increased with an increasing percentage of spruce, which is probably due to the fact that the spruce is an effective collector of atmospheric dry-deposition. The amounts of nutrients that were lost when harvesting logging residues were less than those referred to in the literature. Within a circulation period (100 years), the forest soil gets substantially more nutrients from atmospheric deposition, litter fall and weathering than is lost through harvesting of logging residues after a clear cut. Harvesting of the logging residues makes for a relatively modest increase of the quantity of carbon that is removed from the forest compared to traditional forestry. Due to the fact that the clear cut remains in my study showed a high content of chlorine, there is a risk of corrosion in connection to the incineration of the logging residues in power plants especially at coastal areas/forests. The risk of sulphur -related corrosion is probably rather small, because S concentrations are relatively low in woodchips. The clear cut remains showed rather high heavy metal contents. If the heavy metal contents in this study are representative for the clear cut remains in the coastal forests generally, there might be reason to exert some caution when using the ash for forest fertilizing purposes.

Traditional medicinal uses and biological activities of some plant extracts of African Combretum Loefl., Terminalia L. and Pteleopsis Engl. species

In Africa various species of Combretum, Terminalia and Pteleopsis are used in traditional medicine. Despite of this, some species of these genera have still not been studied for their biological effects to validate their traditional uses. The aim of this work has been to document the ethnomedicinal uses of several species of Combretum and Terminalia in Mbeya region, south-western Tanzania, and to use this information for finding species with good antimicrobial and cytotoxic potential. During a five weeks expedition to Tanzania in spring 1999 sixteen different species of Combretum and Terminalia, as well as Pteleopsis myrtifolia were collected from various locations in the districts of Mbeya, Iringa and Dar-es-Salaam. Traditional healers in seven different villages in the Mbeya region were interviewed in Swahili and Nyakyusa on the medicinal uses of Combretum and Terminalia species shown to them. A questionnaire was used during the interviews. The results of the interviews correlated well between different villages, the same species being used in similar ways in different villages. Of the ten species shown to the healers six were frequently used for treatment of skin diseases, bacterial infections, diarrhea, oedema and wounds. The dried plants were most commonly prepared into hot water decoctions or mixed into maize porridge, Ugali. Infusions made from dried or fresh plant material were also common. Wounds and topical infections were treated with ointments made from the dried plant material mixed with sheep fat. Twenty-one extracts of six species of Combretum and four of Terminalia, collected from Tanzania, were screened for their antibacterial effects against two gram-negative and five gram-positive bacteria, as well as the yeast, Candida albicans, using an agar diffusion method. Most of the screened plants showed substantial antimicrobial activity. A methanolic root extract of T. sambesiaca showed the most potent antibacterial effects of all the plant species screened, and gave a MIC value of 0.9 mg/ml against Enterobacter aerogenes. Also root extracts of T. sericea and T. kaiserana gave excellent antimicrobial effects, and notably a hot water extract of T. sericea was as potent as extracts of this species made from EtOH and MeOH. Thus, the traditional way of preparing T. sericea into hot water decoctions seems to extract antimicrobial compounds. Thirty-five extracts of five species of Terminalia, ten of Combretum and Pteleopsis myrtifolia were screened for their antifungal effects against five species of yeast (Candida spp.) and Cryptococcus neoformans. The species differed from each other to their antifungal effects, some being very effective whereas others showed no antifungal effects. The most effective extracts showed antifungal effects comparable to the standard antibiotics itraconazol and amphotericin B. Species of Terminalia gave in general stronger antifungal effects than those of Combretum. The best effects were obtained with methanolic root extracts of T. sambesiaca, T. sericea and T. kaiserana, and this investigation indicates that decoctions of these species might be used for treatment of HIV-related fungal infections. Twenty-seven crude extracts of eight species of Combretum, five of Terminalia and Pteleopsis myrtifolia were evaluated for their cytotoxic effects against human cancer cell lines (HeLa, cervical carcinoma; MCF 7, breast carcinoma, T 24 bladder carcinoma) and one endothelial cell line (BBCE, bovine brain capillary endothelial cells). The most outstanding effects were obtained with a leaf extract of Combretum fragrans, which nearly totally inhibited the proliferation of T 24 and HeLa cells at a concentration of 25 ug/ml and inhibited 60 % of the growth of the HeLa cells at a concentration of 4.3 ug/ml. The species of Terminalia were less cytotoxically potent than the Combretum species, although T. sericea and T. sambesiaca gave good cytotoxic effects (< 30 % proliferation). In summary this study indicates that some of the species of Terminalia, Combretum and Pteleopsis, used in Tanzanian traditional medicine, are powerful inhibitors of both microbial and cancer cell growth. In depth studies would be needed to find the active compounds behind these biological activities.

The viral coat protein is regulated by HSP70 and HSP40 in Potato virus A infection

Plus-stranded (plus) RNA viruses multiply within a cellular environment as tightly integrated units and rely on the genetic information carried within their genomes for multiplication and, hence, persistence. The minimal genomes of plus RNA viruses are unable to encode the molecular machineries that are required for virus multiplication. This sets requisites for the virus, which must form compatible interactions with host components during multiplication to successfully utilize primary metabolites as building blocks or metabolic energy, and to divert the protein synthesis machinery for production of viral proteins. In fact, the emerging picture of a virus-infected cell displays tight integration with the virus, from simple host and virus protein interactions through to major changes in the physiological state of the host cell. This study set out to develop a method for the identification of host components, mainly host proteins, that interact with proteins of Potato virus A (PVA; Potyvirus) during infection. This goal was approached by developing affinity-tag based methods for the purification of viral proteins complexed with associated host proteins from infected plants. Using this method, host membrane-associated viral ribonucleoprotein (RNP) complexes were obtained, and several host and viral proteins could be identified as components of these complexes. One of the host proteins identified using this strategy was a member of the heat shock protein 70 (HSP70) family, and this protein was chosen for further analysis. To enable the analysis of viral gene expression, a second method was developed based on Agrobacterium-mediated virus genome delivery into plant cells, and detection of virally expressed Renilla luciferase (RLUC) as a quantitative measure of viral gene expression. Using this method, it was observed that down-regulation of HSP70 caused a PVA coat protein (CP)-mediated defect associated with replication. Further experimentation suggested that CP can inhibit viral gene expression and that a distinct translational activity coupled to replication, referred to as replication-associated translation (RAT), exists. Unlike translation of replication-deficient viral RNA, RAT was dependent on HSP70 and its co-chaperone CPIP. HSP70 and CPIP together regulated CP turnover by promoting its modification by ubiquitin. Based on these results, an HSP70 and CPIP-driven mechanism that functions to regulate CP during viral RNA replication and/or translation is proposed, possibly to prevent premature particle assembly caused by CP association with viral RNA.

Long-term clinical outcome after liver transplantation

With transplant rejection rendered a minor concern and survival rates after liver transplantation (LT) steadily improving, long-term complications are attracting more attention. Current immunosuppressive therapies, together with other factors, are accompanied by considerable long-term toxicity, which clinically manifests as renal dysfunction, high risk for cardiovascular disease, and cancer. This thesis investigates the incidence, causes, and risk factors for such renal dysfunction, cardiovascular risk, and cancer after LT. Long-term effects of LT are further addressed by surveying the quality of life and employment status of LT recipients. The consecutive patients included had undergone LT at Helsinki University Hospital from 1982 onwards. Data regarding renal function – creatinine and estimated glomerular filtration rate (GFR) – were recorded before and repeatedly after LT in 396 patients. The presence of hypertension, dyslipidemia, diabetes, impaired fasting glucose, and overweight/obesity before and 5 years after LT was determined among 77 patients transplanted for acute liver failure. The entire cohort of LT patients (540 patients), including both children and adults, was linked with the Finnish Cancer Registry, and numbers of cancers observed were compared to site-specific expected numbers based on national cancer incidence rates stratified by age, gender, and calendar time. Health-related quality of life (HRQoL), measured by the 15D instrument, and employment status were surveyed among all adult patients alive in 2007 (401 patients). The response rate was 89%. Posttransplant cardiovascular risk factor prevalence and HRQoL were compared with that in the age- and gender-matched Finnish general population. The cumulative risk for chronic kidney disease increased from 10% at 5 years to 16% at 10 years following LT. GFR up to 10 years after LT could be predicted by the GFR at 1 year. In patients transplanted for chronic liver disease, a moderate correlation of pretransplant GFR with later GFR was also evident, whereas in acute liver failure patients after LT, even severe pretransplant renal dysfunction often recovered. By 5 years after LT, 71% of acute liver failure patients were receiving antihypertensive medications, 61% were exhibiting dyslipidemia, 10% were diabetic, 32% were overweight, and 13% obese. Compared with the general population, only hypertension displayed a significantly elevated prevalence among patients – 2.7-fold – whereas patients exhibited 30% less dyslipidemia and 71% less impaired fasting glucose. The cumulative incidence of cancer was 5% at 5 years and 13% at 10. Compared with the general population, patients were subject to a 2.6-fold cancer risk, with non-melanoma skin cancer (standardized incidence ratio, SIR, 38.5) and non-Hodgkin lymphoma (SIR 13.9) being the predominant malignancies. Non-Hodgkin lymphoma was associated with male gender, young age, and the immediate posttransplant period, whereas old age and antibody induction therapy raised skin-cancer risk. HRQoL deviated clinically unimportantly from the values in the general population, but significant deficits among patients were evident in some physical domains. HRQoL did not seem to decrease with longer follow-up. Although 87% of patients reported improved working capacity, data on return to working life showed marked age-dependency: Among patients aged less than 40 at LT, 70 to 80% returned to work, among those aged 40 to 50, 55%, and among those above 50, 15% to 28%. The most common cause for unemployment was early retirement before LT. Those patients employed exhibited better HRQoL than those unemployed. In conclusion, although renal impairment, hypertension, and cancer are evidently common after LT and increase with time, patients’ quality of life remains comparable with that of the general population.
