Hausbesuche in der sozialen Arbeit: Traditioneller Ansatz - zu wenig reflektiert

Hausbesuche sind ein traditioneller methodischer Ansatz in der Sozialen Arbeit, der schon vor Jahrhunderten den Armenpflegern zur Unterstützung, aber auch Überprüfung von in Not geratenen Menschen diente. Der Kontrollaspekt trat im Laufe der Jahrhunderte immer stärker in den Vordergrund; auch bei den friendly visitors among the poor um Mary Richmond und der COS (Charity Organisation Society) in den USA (vgl. Richmond 1899) sowie dem Anliegen von Alice Salomon, Hausbesuche als ein mögliches Ermittlungsinstrument im Rahmen der Erstellung von sozialen Diagnosen zu nutzen (vgl. Salomon 1927). Das Dilemma zwischen Hilfe und Kontrolle zieht sich also wie ein roter Faden durch die Geschichte von Hausbesuchen und nimmt auch in der hier vorgestellten Studie einen großen Raum ein

The epidemiology and biology of pulmonary metastases

Our goal in this chapter is to explore the complex processes of metastasis and why there is a predisposition for this to occur in the lung. In addition, we aim to describe the incidence of pulmonary metastases in various contexts and based on the origin of the primary tumor. There are unique characteristics of the pulmonary system that make metastases more likely to occur in the lung than anywhere else in the body. Some of these characteristics include receiving the entire cardiac output every minute, having the densest capillary bed in the body, and being the first reservoir of most lymphatic drainage entering the venous system. There are multiple postulated routes of metastasis to the pulmonary system including hematogenous and lymphatic routes with early or late dissemination. The vascularization of pulmonary metastases is variable and complex, often recruiting supply from bronchial and pulmonary origin. There are also many biochemical factors in the tumor microenvironment that play a key role in the development of lung metastases including vascular endothelial growth factor (VEGF), interleukin-8 (IL-8), very late antigen 4 (VLA-4) and intercellular adhesion molecule 1 (ICAM-1). Studies vary widely in reported rates of pulmonary metastases due to differences in clinical study design, however, it is commonly accepted that up to half of autopsies performed on patients who died of malignancy have pulmonary metastases. In a surgical series describing the incidence of primary cancer types with resected pulmonary metastases the most common sites were thyroid, colon, breast, genitourinary tract, skin, liver, breast, and adrenal glands

Shifts in microbial community structure and function in stream sediments during experimentally simulated riparian succession

Successional changes of terrestrial vegetation can profoundly influence stream ecosystem structure and function. We hypothesized that microbial enzyme production and community structure in stream beds depend on terrestrial litter inputs that reflect different stages of riparian succession. Outdoor experimental channels were supplied with leaf-litter of varying quantities and qualities to mimic litter supply during five successional stages: (1) an initial biofilm stage; (2) an open-land stage with grass litter; (3) a transitional stage with mixed grass and birch litter; (4) an early forest stage with birch litter; and (5) an advanced forest stage with 2.5 × the amount of birch litter. Mean potential activities of nitrogen- and phosphorus-acquiring enzymes in sediments (20.7 and 67.3 μmol g−1 dry mass) were 12-70 times greater than those of carbon-acquiring enzymes (0.96-1.71 μmol g−1 dry mass), with the former reduced 1.3-8.3-fold in channels with tree litter. These patterns could suggest gradually diminishing nutrient limitation of microbial activity during riparian succession, potentially linked both to an increasing supply by the added litter and to a lower nutrient demand as algal biomass and labile carbon supply by photosynthetic exudates declined. As the observed shifts in nutrient-acquiring enzymes were reflected in changes of sediment microbial communities, these results indicate that both the type and density of terrestrial vegetation control microbial community structure and function in stream sediments, particularly enzyme production related to nutrient cyclin

Fear information and the development of fears during childhood: effects on implicit fear responses and behavioural avoidance

Field, Argyris and Knowles (Behav Res Ther 39 (2001) 1259), and Field, Hamilton, Knowles and Plews (Behav Res Thera 41 (2003) 113) have developed a prospective paradigm for testing Rachman’s (Behav Res Ther 15 (1977) 375) proposition that fear information is important in the development of fears and phobias in children. Despite this paradigm being an advance on retrospective reports, the research so far has been restricted to self-reported fear beliefs measured after the information is given. This gives rise to two possible shortcomings: (1) the effects could simply reflect demand characteristics resulting from children conforming to the experimental demands, and (2) although fear information changes beliefs, this might not translate into the behavioural change that would be expected if this information has a powerful effect relevant to the development of pathological fear. This paper describes an experiment that attempts to address these concerns by improving Field et al.’s (2001, 2003) basic paradigm but with the addition of two measures: (1) a behavioural measure of avoidance, and (2) an implicit attitude task that should not be susceptible to deliberate attempts to conform to experimental demands. The result showed that negative and positive information have dramatic, and opposite, effects on self-reported fear beliefs, behavioural avoidance and implicit attitudes. There were no effects of gender on any of these results. This study fully supports Rachman’s model and suggests that past work does not merely reflect demand characteristics and that fear information increases behavioural avoidance as well as fear beliefs

Antisense-mediated exon skipping: a therapeutic strategy for titin-based dilated cardiomyopathy

Frameshift mutations in the TTN gene encoding titin are a major cause for inherited forms of dilated cardiomyopathy (DCM), a heart disease characterized by ventricular dilatation, systolic dysfunction, and progressive heart failure. To date, there are no specific treatment options for DCM patients but heart transplantation. Here, we show the beneficial potential of reframing titin transcripts by antisense oligonucleotide (AON)-mediated exon skipping in human and murine models of DCM carrying a previously identified autosomal-dominant frameshift mutation in titin exon 326. Correction of TTN reading frame in patient-specific cardiomyocytes derived from induced pluripotent stem cells rescued defective myofibril assembly and stability and normalized the sarcomeric protein expression. AON treatment in Ttn knock-in mice improved sarcomere formation and contractile performance in homozygous embryos and prevented the development of the DCM phenotype in heterozygous animals. These results demonstrate that disruption of the titin reading frame due to a truncating DCM mutation canbe restored by exon skipping in both patient cardiomyocytes invitro and mouse heart invivo, indicating RNA-based strategies as a potential treatment option for DCM

The SMILe integrated care model in allogeneic SteM cell TransplantatIon faciLitated by eHealth: a protocol for a hybrid effectiveness-implementation randomised controlled trial

While effectiveness outcomes of eHealth-facilitated integrated care models (eICMs) in transplant and oncological populations are promising, implementing and sustaining them in real-world settings remain challenging. Allogeneic stem cell transplant (alloSCT) patients could benefit from an eICM to enhance health outcomes. To combat health deterioration, integrating chronic illness management, including continuous symptom and health behaviour monitoring, can shorten reaction times. We will test the 1st-year post-alloSCT effectiveness and evaluate bundled implementation strategies to support the implementation of a newly developed and adapted eICM in allogeneic stem cell transplantation facilitated by eHealth (SMILe-ICM). SMILe-ICM has been designed by combining implementation, behavioural, and computer science methods. Adaptions were guided by FRAME and FRAME-IS. It consists of four modules: 1) monitoring & follow-up; 2) infection prevention; 3) physical activity; and 4) medication adherence, delivered via eHealth and a care coordinator (an Advanced Practice Nurse). The implementation was supported by contextually adapted implementation strategies (e.g., creating new clinical teams, informing local opinion leaders).; Using a hybrid effectiveness-implementation randomised controlled trial, we will include a consecutive sample of 80 adult alloSCT patients who were transplanted and followed by University Hospital Basel (Switzerland). Inclusion criteria are basic German proficiency; elementary computer literacy; internet access; and written informed consent. Patients will be excluded if their condition prevents the use of technology, or if they are followed up only at external centres. Patient-level (1:1) stratified randomisation into a usual care group and a SMILe-ICM group will take place 10 days pre-transplantation. To gauge the SMILe-ICM's effectiveness primary outcome (re-hospitalisation rate), secondary outcomes (healthcare utilization costs; length of inpatient re-hospitalizations, medication adherence; treatment and self-management burden; HRQoL; Graft-versus-Host Disease rate; survival; overall survival rate) and implementation outcomes (acceptability, appropriateness, feasibility, fidelity), we will use multi-method, multi-informant assessment (via questionnaires, interviews, electronic health record data, cost capture methods).; The SMILe-ICM has major innovative potential for reengineering alloSCT follow-up care, particularly regarding short- and medium-term outcomes. Our dual focus on implementation and effectiveness will both inform optimization of the SMILe-ICM and provide insights regarding implementation strategies and pathway, understudied in eHealth-facilitated ICMs in chronically ill populations.; ClinicalTrials.gov.
