Promoting Integrated Care through a Global Treatment Budget
Introduction: Since 2003, as a means of enabling integrated care the German mental health care system has offered the innovative option of agreeing a Global Treatment Budget (GTB, also known as a regional psychiatric budget or innovative flexible and integrative forms of treatment FIT) with health insurers and regional care providers across sectors. Despite promoting legal frameworks and positive evidence on improving quality of patient care, this model has not spread widely. The aim of this study is to identify inhibiting and facilitating factors for the innovation diffusion.
Theory and methods: We conducted expert interviews with 19 actors from nine German regions involved in GTBs, using a self-developed questionnaire based on Rogers' theory on innovation diffusion extended by the innovation system approach. Interviews were analysed applying qualitative content analysis. Code categories were built deductively operationalising Rogers' theory and inductively from the data generated.
Results: Observability of the innovation was perceived as good, but trialability, reversibility, compatibility with regular care structures as low, and thus the perceived risks of adoption as high. Complexity up to implementation is high, caused by numerous individuals and stakeholder groups involved. Diffusion took place in environments of strong individuals with venturesomeness, opinion leadership, and informal networking. As favourable framework conditions the monopoly and non-profit position of hospitals in well-defined care regions were identified.
Discussion and conclusions: Diffusion of integrated care could be accelerated by dissolving the multi-actor constellation, changing the communication strategy, and adapting the legal framework
Heme binding properties of heterologously expressed spinach cytochrome b6: Implications for transmembrane b-type cytochrome formation
AbstractIn vivo and in vitro requirements for the formation of cytochrome b6 were examined to analyze the mechanisms of transmembrane b-type cytochrome formation. After heterologous expression of spinach cytochrome b6, formation of the holo-cytochrome was observed within the E. coli inner membrane. The transmembrane orientation of cytochrome b6 appeared not to be critical for heme binding and holo-cytochrome formation. Furthermore, in vitro reconstitution of cytochrome b6 was possible under oxidizing as well as under reducing conditions. Taken together these observations strongly indicate that transmembrane b-type cytochromes can spontaneously assemble in vitro as well as in a membrane

Respiratory Muscle Function Tests and Diaphragm Ultrasound Predict Nocturnal Hypoventilation in Slowly Progressive Myopathies
Introduction: In slowly progressive myopathies, diaphragm weakness early manifests through sleep-related hypoventilation as reflected by nocturnal hypercapnia. This study investigated whether daytime tests of respiratory muscle function and diaphragm ultrasound predict hypercapnia during sleep. Methods: Twenty-seven patients with genetic myopathies (myotonic dystrophy type 1 and 2, late-onset Pompe disease, facioscapulohumeral dystrophy; 48 +/- 11 years) underwent overnight transcutaneous capnometry, spirometry, measurement of mouth occlusion pressures, and diaphragm ultrasound. Results: Sixteen out of 27 patients showed nocturnal hypercapnia (peak p(tc)CO(2) >= 50 mmHg for >= 30 min or increase in p(tc)CO(2) by 10 mmHg or more from the baseline value). In these patients, forced vital capacity (FVC; % predicted) and maximum inspiratory pressure (MIP; % of lower limit or normal or LLN) were significantly reduced compared to normocapnic individuals. Nocturnal hypercapnia was predicted by reduction in FVC of Conclusion: In slowly progressive myopathies, nocturnal hypercapnia is predicted by FVC 8.0 cm/s on diaphragm ultrasound.</p

Heart Failure Results in Inspiratory Muscle Dysfunction Irrespective of Left Ventricular Ejection Fraction
Background: Exercise intolerance in heart failure with reduced ejection fraction (HFrEF) or heart failure with preserved ejection fraction (HFpEF) results from both cardiac dysfunction and skeletal muscle weakness. Respiratory muscle dysfunction with restrictive ventilation disorder may be present irrespective of left ventricular ejection fraction and might be mediated by circulating pro-inflammatory cytokines. Objective: To determine lung and respiratory muscle function in patients with HFrEF/HFpEF and to determine its associations with exercise intolerance and markers of systemic inflammation. Methods: Adult patients with HFrEF (n = 22, 19 male, 61 +/- 14 years) and HFpEF (n = 8, 7 male, 68 +/- 8 years) and 19 matched healthy control subjects underwent spirometry, measurement of maximum mouth occlusion pressures, diaphragm ultrasound, and recording of transdiaphragmatic and gastric pressures following magnetic stimulation of the phrenic nerves and the lower thoracic nerve roots. New York Heart Association (NYHA) class and 6-min walking distance (6MWD) were used to quantify exercise intolerance. Levels of circulating interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were measured using ELISAs. Results: Compared with controls, both patient groups showed lower forced vital capacity (FVC) (p < 0.05), maximum inspiratory pressure (PImax), maximum expiratory pressure (PEmax) (p < 0.05), diaphragm thickening ratio (p = 0.01), and diaphragm strength (twitch transdiaphragmatic pressure in response to supramaximal cervical magnetic phrenic nerve stimulation) (p = 0.01). In patients with HFrEF, NYHA class and 6MWD were both inversely correlated with FVC, PImax, and PEmax. In those with HFpEF, there was an inverse correlation between amino terminal pro B-type natriuretic peptide levels and FVC (r = -0.77, p = 0.04). In all HF patients, IL-6 and TNF-alpha were statistically related to FVC. Conclusions: Irrespective of left ventricular ejection fraction, HF is associated with respiratory muscle dysfunction, which is associated with increased levels of circulating IL-6 and TNF-alpha
COVID-19 mortality in cirrhosis is determined by cirrhosis-associated comorbidities and extrahepatic organ failure: Results from the multinational LEOSS registry
Background and Objective International registries have reported high mortality rates in patients with liver disease and COVID-19. However, the extent to which comorbidities contribute to excess COVID-19 mortality in cirrhosis is controversial. Methods We used the multinational Lean European Open Survey on SARS-CoV-2-infected patients (LEOSS) to identify patients with cirrhosis documented between March 2020 and March 2021, when the wild-type and alpha variant were predominant. We compared symptoms, disease progression and mortality after propensity score matching (PSM) for age, sex, obesity, smoking status, and concomitant diseases. Mortality was also compared with that of patients with spontaneous bacterial peritonitis (SBP) without SARS-CoV-2 infection, a common bacterial infection and well-described precipitator of acute-on-chronic liver failure. Results Among 7096 patients with SARS-CoV-2 infection eligible for analysis, 70 (0.99%) had cirrhosis, and all were hospitalized. Risk factors for severe COVID-19, such as diabetes, renal disease, and cardiovascular disease were more frequent in patients with cirrhosis. Case fatality rate in patients with cirrhosis was 31.4% with the highest odds of death in patients older than 65 years (43.6% mortality; odds ratio [OR] 4.02; p = 0.018), Child-Pugh class C (57.1%; OR 4.00; p = 0.026), and failure of two or more organs (81.8%; OR 19.93; p = 0.001). After PSM for demographics and comorbidity, the COVID-19 case fatality of patients with cirrhosis did not significantly differ from that of matched patients without cirrhosis (28.8% vs. 26.1%; p = 0.644) and was similar to the 28-day mortality in a comparison group of patients with cirrhosis and SBP (33.3% vs. 31.5%; p = 1.000). Conclusions In immunologically naive patients with cirrhosis, mortality from wild-type SARS-CoV-2 and the alpha variant is high and is largely determined by cirrhosis-associated comorbidities and extrahepatic organ failure
