Global change of surgical and oncological clinical practice in urology during early COVID-19 pandemic.

OBJECTIVES: While the coronavirus disease 2019 (COVID-19) pandemic captures healthcare resources worldwide, data on the impact of prioritization strategies in urology during pandemic are absent. We aimed to quantitatively assess the global change in surgical and oncological clinical practice in the early COVID-19 pandemic. METHODS: In this cross-sectional observational study, we designed a 12-item online survey on the global effects of the COVID-19 pandemic on clinical practice in urology. Demographic survey data, change of clinical practice, current performance of procedures, and current commencement of treatment for 5 conditions in medical urological oncology were evaluated. RESULTS: 235 urologists from 44 countries responded. Out of them, 93% indicated a change of clinical practice due to COVID-19. In a 4-tiered surgery down-escalation scheme, 44% reported to make first cancellations, 23% secondary cancellations, 20% last cancellations and 13% emergency cases only. Oncological surgeries had low cancellation rates (%): transurethral resection of bladder tumor (27%), radical cystectomy (21-24%), nephroureterectomy (21%), radical nephrectomy (18%), and radical orchiectomy (8%). (Neo)adjuvant/palliative treatment is currently not started by more than half of the urologists. COVID-19 high-risk-countries had higher total cancellation rates for non-oncological procedures (78% vs. 68%, p = 0.01) and were performing oncological treatment for metastatic diseases at a lower rate (35% vs. 48%, p = 0.02). CONCLUSION: The COVID-19 pandemic has affected clinical practice of 93% of urologists worldwide. The impact of implementing surgical prioritization protocols with moderate cancellation rates for oncological surgeries and delay or reduction in (neo)adjuvant/palliative treatment will have to be evaluated after the pandemic.

Prognostic significance of PD-1 and PD-L1 positive tumor-infiltrating immune cells in ovarian carcinoma.

INTRODUCTION: Ovarian carcinoma is associated with the highest mortality of all gynecologic malignancies. Even after optimal treatment, prognosis remains poor. There is no established biomarker to predict individual patient outcome. OBJECTIVE: To evaluate the prognostic significance of PD-1 and PD-L1 expression in tumor tissues from patients with ovarian cancer. METHODS: Tissue micro-arrays were prepared from routinely formalin-fixed, paraffin-embedded tumor tissues and examined immunohistochemically for the expression of programed cell death protein 1 (PD-1) and one of its ligands (PD-L1) on epithelial tumor cells, as well as on tumor- and stroma-infiltrating immune cells. RESULTS: The presence of PD-1 positive tumor-infiltrating immune cells was significantly associated with prolonged overall survival. PD-1 and PD-L1 positive tumor-infiltrating immune cells were associated with the presence of lymph node metastases and higher tumor grade. Interestingly, the amount of PD-1/PD-L1 positive tumor- and stroma-infiltrating immune cells independent of PD-1 or PD-L1 expression did not show any significant correlation with prognostic variables. CONCLUSION: Our results highlight the prognostic value of PD-1 and PD-L1 positive tumor-infiltrating immune cells in ovarian carcinoma. Their association with favorable prognosis supports the hypothesis that the expression of PD-1 and PD-L1 on tumor-infiltrating immune cells represents a strong immune response.

[Implementation of the Preventive Health Care Act at the Level of The Federal States: An Analysis of the Framework Agreements]. / Die Umsetzung des Präventionsgesetzes auf Länderebene: Eine Analyse der Landesrahmenvereinbarungen.

BACKGROUND: The implementation of the Preventive Health Care Act 2015 requires framework agreements between social insurances and ministries on the state level (Länder). GOALS: This article analyses the 15 agreements already concluded and provides an overview of similarities and differences between states. METHODS: We conducted a qualitative content analysis for all 15 agreements. In a first step, we compared the agreements with the model agreement that had informed the negotiations in all states, and identified for each paragraph of the agreement divergent content. In a second step, we compared the divergent content and built subcategories. Third, we classified similarities and differences of each category. For this article, we selected 4 categories: goals and fields of action, committees and regulatory structures, cooperation requirements, cooperation with further actors. RESULTS: All agreements refer to the nationally agreed health goals, some define further, state-specific goals. Furthermore, the agreements provide regulations regarding the goal definition process: some processes only include the subscribers of the agreement, while others involve all relevant stakeholders. New regulatory structures are created in almost all states, but their institutional design and mode of interaction vary highly between state. In 4 states the new structures aim at establishing a dialogue, in 3 states, the goal is to enable coordination, and in 7 states decision-making bodies are set up. Almost all agreements are missing concrete commitments regarding cooperation with other relevant actors on state and local level. CONCLUSION: Most agreements are very general and their binding character is low. The agreements merely set the framework that now needs to be filled. Hence, evaluating the actual implementation of the agreements will only be possible in a few years.

Ankylosing spondylitis causes high burden to patients and the healthcare system: results from a German claims database analysis.

To compare healthcare resource utilization and costs between ankylosing spondylitis (AS) patients and a matched sample from the general population without AS covered by the German Statutory Health Insurance (SHI) system, a non-interventional retrospectively matched cohort analysis was conducted using anonymized SHI claims data. Data from January 1st, 2011 through December 31st, 2014 were analyzed. Individuals with a coded diagnosis of AS during the enrollment period comprising the full year of 2013 were directly matched (1:5) to individuals without AS diagnosis in the whole study period by age, gender, hospitalizations, and comorbidities. All-cause healthcare resource utilization and direct costs were analyzed for the year 2013. Statistical tests were applied to compare the differences between the two sampled populations. In 2013, 10,208 AS patients were identified and matched to a sample of 51,040 patients without AS from the general population. Healthcare resource utilization was significantly higher in all healthcare sectors (inpatient, outpatient, pharmaceuticals, remedies, devices and aids, and sick leave) in the AS cohort. Mean all-cause healthcare costs per patient were about €2475 higher in the AS cohort compared to the general population. Most important cost drivers were hospitalizations and pharmaceuticals in terms of bDMARDs prescribed in 10% of the patients. Real-world data from this German claims database analysis showed that AS is associated with a substantial incremental economic burden to the healthcare system.

[Health promotion networks for children and youth on the local level : An overview of the status quo in Germany]. / Vernetzte kommunale Gesundheitsförderung für Kinder und Jugendliche : Überblick über den Status quo in Deutschland.

In recent years, more and more municipalities in Germany have started to establish cross-sectoral health promotion networks for children and teenagers. They are supported by several initiatives at the state and federal level. The aim of this article is to provide an overview of these initiatives and to describe the central barriers for the implementation of health promotion networks on the local level. For this purpose, the authors first outline the role of municipalities in health promotion in Germany in general, and then describe the initiatives in more detail. The authors identify four central obstacles for implementing health promotion networks on the local level: the tight financial situation of many municipalities, difficulties of the local public service in realizing intersectoral cooperation, the traditionally weak role of the local health service, and missing evidence for Germany regarding the effectiveness of networks and integrated strategies. In addition, the article presents two alternative solutions: Great Britain and Västerbotten, a county in Sweden.

IFN-γ and TNF Induce Senescence and a Distinct Senescence-Associated Secretory Phenotype in Melanoma.

Immune checkpoint blockade (ICB) therapy is a central pillar of melanoma treatment leading to durable response rates. Important mechanisms of action of ICB therapy include disinhibition of CD4+ and CD8+ T cells. Stimulated CD4+ T helper 1 cells secrete the effector cytokines interferon-gamma (IFN-γ) and tumor necrosis factor alpha (TNF), which induce senescence in tumor cells. Besides being growth-arrested, senescent cells are metabolically active and secrete a large spectrum of factors, which are summarized as senescence-associated secretory phenotype (SASP). This secretome affects the tumor growth. Here, we compared the SASP of cytokine-induced senescent (CIS) cells with the SASP of therapy-induced senescent (TIS) cells. Therefore, we established in vitro models for CIS and TIS in melanoma. The human melanoma cell lines SK-MEL-28 and WM115 were treated with the cytokines IFN-γ and TNF as CIS, the chemotherapeutic agent doxorubicin, and the cell cycle inhibitor palbociclib as TIS. Then, we determined several senescence markers, i.e., growth arrest, p21 expression, and senescence-associated ß-galactosidase (SA-ß-gal) activity. For SASP analyses, we measured the regulation and secretion of several common SASP factors using qPCR arrays, protein arrays, and ELISA. Each treatment initiated a stable growth arrest, enhanced SA-ß-gal activity, and-except palbociclib-increased the expression of p21. mRNA and protein analyses revealed that gene expression and secretion of SASP factors were severalfold stronger in CIS than in TIS. Finally, we showed that treatment with the conditioned media (CM) derived from cytokine- and palbociclib-treated cells induced senescence characteristics in melanoma cells. Thus, we conclude that senescence induction via cytokines may lead to self-sustaining senescence surveillance of melanoma.

Smartglass augmented reality-assisted targeted prostate biopsy using cognitive point-of-care fusion technology.

INTRODUCTION: MRI-guided targeted biopsy has become standard of care for diagnosis of prostate cancer, with establishment of several biopsy techniques and platforms. Augmented reality smart glasses have emerged as novel technology to support image-guided interventions. We aimed to investigate its usage while prostate biopsy. METHODS: MRI with PIRADS-lesions ≥3 was uploaded to smart glasses (Vuzix BladeR ) and augmented reality smart glasses-assisted targeted biopsy (SMART-TB) of the prostate was performed using cognitive fusion technology at the point of care. Detection rates were compared to systematic biopsy. Feasibility for SMART-TB was assessed (10 domains from bad [1] to excellent [10]). RESULTS: SMART-TB was performed for four patients. Prostate cancer detection was more likely for SMART-TB (46%; 13/28) than for systematic biopsy (27%; 13/48). Feasibility scores were high [8-10] for practicality, multitasking, execution speed, comfort and device weight and low [1-4] for handling, battery and image quality. Median execution time: 28 min; Investment cost smart glass: 1017 USD. CONCLUSION: First description of SMART-TB demonstrated convenient feasibility. This novel technology might enhance diagnosis of prostate cancer in future.

The timing of initial imaging in testicular cancer: impact on radiological findings and clinical decision making.

BACKGROUND: In testicular cancer determination of clinical stage and recommendation of therapeutic strategy after inguinal orchiectomy are based on primary imaging by CT-scan of the chest and CT- or MRI-abdomen. It has not been investigated so far whether the imaging should be performed before or after primary testicular surgery. Staging before surgery means exposing all patients to CT radiation irrespective of ensured histologic malignancy while postoperative staging could pose a risk in biased clinical decision making by increased presence of unspecific lymph node enlargement caused by postsurgical effects. Therefore, we aimed to investigate the association between the timing of initial staging and occurrence of unspecific lymph node enlargement and adjuvant therapies after inguinal orchiectomy. METHODS: We retrospectively evaluated clinical and radiological data from 236 patients who had undergone inguinal orchiectomy for testicular cancer at our department. Statistical analysis was performed to determine whether the occurrence of unspecific lymph node enlargement or the rate of adjuvant therapies were influenced by timing of initial staging (preoperative vs. postoperative). RESULTS: The postoperative imaging cohort showed significant more inguinal, pelvic and retroperitoneal unspecific lymph node enlargement than the preoperative imaging cohort. Simultaneous occurrence of inguinal or pelvic lymph node enlargement together with retroperitoneal enlargements could only be found in the postoperative imaging cohort. No difference regarding adjuvant therapies could be found. CONCLUSIONS: Timing of imaging affects the detection rate of unspecific lymph node enlargements but does not show a significant effect on the rate of adjuvant therapies.

Evaluation of old landfills--a thermoanalytical and spectroscopic approach.

Abandoned landfills and dumps, where untreated waste materials were deposited in the past, are a main anthropogenic source of relevant gaseous emissions. The determination of stability is a crucial target in the context of landfill risk assessment. FTIR spectroscopy and simultaneous thermal analysis in association with multivariate statistical methods were applied to landfill materials in order to get information on the kind of waste and its reactivity. The spectral and thermal patterns are fingerprints of the material. Industrial waste and the material from a 5-year-old reactor landfill were distinguished from the defined classes of mechanically-biologically treated ("MBT") waste and 30 to 40-year-old stable landfills containing municipal solid waste and construction waste ("LF") by a classification model based on soft independent modeling of class analogy (SIMCA). Degradation experiments were carried out with the fresh material originating from one MBT plant that was subjected to aerobic and anaerobic conditions in lab-scale reactors. These samples were compared to samples of one reactor landfill and to the landfill fraction from the MBT plant to demonstrate the efficiency of the biological pretreatment before final disposal. Prediction models that are based on spectral or thermal characteristics and the corresponding reference analyses were calculated by means of a partial least squares regression (PLS-R). The developed models of the biological oxygen demand (BOD) and the dissolved organic carbon (DOC) were based on spectral data, the models of the total organic carbon (TOC) and total nitrogen (TN) were based on thermal data (heat flow profiles and mass spectra of combustion gases). Preliminary results are discussed. The enthalpy of the materials decreases with progressing mineralization, whereas the enthalpy of the remaining organic matter increases. The ratio of the enthalpies was used as an indicator of stability. Selected samples comprising old landfills, a recent reactor landfill, MBT landfills and MBT materials were classified according to the calculated ratios.

How to enhance humification during composting of separately collected biowaste: impact of feedstock and processing.

Conventional parameters (loss on ignition, total organic carbon, total nitrogen, C/N-ratio, respiration activity (RA4), compost status (= 'Rottegrad'), NH4-N and NO3-N) are not correlated to humification. At best, they provide information on the biological stability (status of degradation) of composts. Humic substances which are a source of stable organic matter and nutrients are discussed as a parameter describing compost quality. Thus, in the present research project a photometric method evaluating humic acids was used to characterize the quality of 211 Austrian and foreign composts made from source-separated collected biowaste or sewage sludge. Furthermore, parameters influencing the formation of humic acids during the rotting process were investigated by implementing rotting experiments in the laboratory as well as in composting plants. The analysed composts showed humic acid contents between 2.5 and 47 %, calculated on a organic dry matter (oDM) basis. In addition to the duration of treatment the main influence on humification was the feedstock used. Stabilized sewage sludge, biowaste after intensive anaerobic pre-treatment or biowaste with low reactivity (RA4) or uniform composition (e.g. mainly grass) showed a low formation of humic acids. For optimum humification the feedstock needed to contain components that are well balanced from scarcely to easily degradable compounds. Processing also influenced humification. Open windrow systems and reactor systems allow the same quality to be produced when operated well, but optimizing mineralization (e.g. very intensive aeration) showed negative effects. The positive condition required for humification is an unhurried (not too intense) degradation with long-lasting biological activity in which microbes have enough time to use the metabolic products of degradation for humification.

Cancer immune control needs senescence induction by interferon-dependent cell cycle regulator pathways in tumours.

Immune checkpoint blockade (ICB)-based or natural cancer immune responses largely eliminate tumours. Yet, they require additional mechanisms to arrest those cancer cells that are not rejected. Cytokine-induced senescence (CIS) can stably arrest cancer cells, suggesting that interferon-dependent induction of senescence-inducing cell cycle regulators is needed to control those cancer cells that escape from killing. Here we report in two different cancers sensitive to T cell-mediated rejection, that deletion of the senescence-inducing cell cycle regulators p16Ink4a/p19Arf (Cdkn2a) or p21Cip1 (Cdkn1a) in the tumour cells abrogates both the natural and the ICB-induced cancer immune control. Also in humans, melanoma metastases that progressed rapidly during ICB have losses of senescence-inducing genes and amplifications of senescence inhibitors. Metastatic cells also resist CIS. Such genetic and functional alterations are infrequent in metastatic melanomas regressing during ICB. Thus, activation of tumour-intrinsic, senescence-inducing cell cycle regulators is required to stably arrest cancer cells that escape from eradication.

Comparative assessment of docetaxel for safety and efficacy between hormone-sensitive and castration-resistant metastatic prostate cancer.

OBJECTIVE: To compare toxicity and response of docetaxel chemotherapy between metastatic hormone-sensitive prostate cancer (mHSPC) and castration-resistant metastatic prostate cancer (mCRPC) patients of the same therapeutic era for assessing of upfront docetaxel against the benchmark of docetaxel in the castrate resistant stage in the setting outside of clinical trials. METHODS: A prospectively collected database of real-world prostate cancer patients receiving docetaxel was divided in mHSPC and mCRPC cases and retrospectively analyzed. Principal objectives were toxicity measured by the common criteria of adverse events terminology and response characterized by Prostate specific antigen decline and radiographic progression-free disease at restaging. The prognostic value of suspected variables for grade 3 to 5 toxicity and response was investigated by logistic regression analysis. RESULTS: Of 72 patients 34 (47%) were treated for mHSPC and 38 (53%) for mCRPC. Patients with mCRPC were older and had worse performance status (P< 0.01). In mHSPC total number of grade 3 to 5 adverse events (24, median 0, interquartile range 0-1) was significantly less than in mCRPC (46, median 1, interquartile range 1-2) (P = 0.01). Multivariable analysis revealed age as independent predictive variable for grade 3 to 5 toxicity (P = 0.03) but not disease stage, Prostate specific antigen predocetaxel, volume of disease, and Eastern Cooperative Oncology Group performance status (P > 0.05). Objective response was significantly higher in mHSPC compared to mCRPC patients (P < 0.01). Multivariable analysis confirmed mHSPC stage as independent prognostic factor for radiographic progression free disease at restaging (P < 0.01). CONCLUSIONS: The association of age with toxicity and of mHSPC stage with response resulted in significantly fewer grade 3 to 5 adverse events but higher response rates for upfront docetaxel in mHSPC compared with docetaxel in the later mCRPC stage.

Nocturnal respiratory rate as a predictor of mortality in patients with acute coronary syndrome.

Background: Patients with acute coronary syndrome (ACS) are at risk especially in the period shortly after the event. Alterations in respiratory control have been associated with adverse prognosis. The aim of our study was to assess if the nocturnal respiratory rate (NRR) is a predictor of mortality in patients with ACS presenting in the emergency department. Methods: Clinically stable consecutive patients with ACS aged ≥ 18 years were prospectively enrolled. The Global Registry of Acute Coronary Events (GRACE) score and left ventricular ejection fraction (LVEF) were assessed for all patients. The average NRR over a period of 6 hours was determined by the records of the surveillance monitors in the first night after admission. Primary and secondary endpoints were intrahospital and 2 years all-cause mortality, respectively. Results: Of the 860 patients with ACS, 21 (2.4%) died within the intrahospital phase and 108 patients (12.6%) died within the subsequent 2 years. The NRR was a significant predictor of both endpoints and was independent from the GRACE score and LVEF. Implementing the NRR into the GRACE risk model leads to a significant increase of the C-statistics especially for prediction of intrahospital mortality. Conclusion: The NRR is an independent predictor of mortality in patients with ACS.

Determination of leachate compounds relevant for landfill aftercare using FT-IR spectroscopy.

Controlling and monitoring of emissions from municipal solid waste (MSW) landfills is important to reduce environmental damage and health risks. Therefore, simple and meaningful monitoring tools are required. This paper presents how Fourier Transform Infrared (FT-IR) Spectroscopy can be used to monitor leachate from various landfill sites. The composition of percolated leachate provides information about reactivity or stability of organic matter in landfills. Chemical compounds of investigated leachate are depicted by distinct spectral pattern. Partial least squares regression (PLS-R) models, a multivariate analysis tool, were developed based on infrared spectra to determine simultaneously conventional parameters such as ammonium, nitrate, sulfate, and dissolved organic carbon. The developed models are appropriate for application in waste management practice with respect to their excellent coefficients of determination, namely R(2)=0.99, 0.99, 0.98, and 0.98, their low errors of cross-validation and their high ratios of performance to deviation (RPD=9.3, 12.5, 6.5, 7.3). Thus, FT-IR spectroscopy turned out to be a reliable, time-saving tool to determine four parameters relevant for landfill aftercare monitoring by one single easy adaptable measurement.

Cost-effectiveness analysis of a vaccination program for the prevention of herpes zoster and post-herpetic neuralgia in adults aged 50 and over in Germany.

Herpes zoster (HZ; shingles) is a common viral disease that affects the nerves and surrounding skin causing a painful dermatomal rash and leading to debilitating complications such as, mainly, post-herpetic neuralgia (PHN). Currently, there is no effective treatment for HZ and PHN. The objective of this study was to assess the cost-effectiveness of a HZ vaccination program in Germany. An existing Markov Model was adapted to the German healthcare setting to compare a vaccination policy to no vaccination on a lifetime time-horizon, considering 2 scenarios: vaccinating people starting at the age of 50 or at the age of 60 years, from the perspective of the statutory health insurance (SHI) and the societal perspective. According to the perspective, vaccinating 20% of the 60+ German population resulted in 162,713 to 186,732 HZ and 31,657 to 35,793 PHN cases avoided. Corresponding incremental cost-effectiveness ratios (ICER) were 39,306 €/QALY from the SHI perspective and 37,417 €/QALY from a societal perspective. Results for the 50+ German population ranged from 336,468 to 394,575 HZ and from 48,637 to 56,087 PHN cases avoided from the societal perspective. Corresponding ICER were 39,782 €/QALY from a SHI perspective and 32,848 €/QALY from a societal perspective. Sensitivity analyses showed that results are mainly impacted by discount rates, utility values and use of alternative epidemiological data.The model indicated that a HZ vaccination policy in Germany leads to significant public health benefits and could be a cost-effective intervention. The results were robust and consistent with local and international existing literature.

Cost-effectiveness of childhood rotavirus vaccination in Germany.

BACKGROUND: Rotavirus (RV) causes a highly contagious gastroenteritis especially in children under five years of age. Since 2006 two RV-vaccines are available in Europe (Rotarix(®) and RotaTeq(®)). To support informed decision-making within the German Standing Committee on Vaccination (STIKO) the cost-effectiveness of these two vaccines was evaluated for the German healthcare setting. METHODS: A Markov model was developed to evaluate the cost-effectiveness from the statutory health insurance (SHI) and from the societal perspective. RV-cases prevented, RV-associated hospitalizations avoided, and quality-adjusted life years (QALY) gained were considered as health outcomes. RV-incidences were calculated based on data from the national mandatory disease reporting system. RV-vaccine efficacy was determined as pooled estimates based on data from randomized controlled trials. Vaccine list prices and price catalogues were used for cost-assessment. Effects and costs were discounted with an annual discount rate of 3%. RESULTS: The base-case analysis (SHI-perspective) resulted in an incremental cost-effectiveness and cost-utility ratio for Rotarix(®) of € 184 per RV-case prevented, € 2457 per RV-associated hospitalization avoided, and € 116,973 per QALY gained. For RotaTeq(®), the results were € 234 per RV-case prevented, € 2622 per RV-associated hospitalization avoided, and € 142,732 per QALY gained. Variation of various parameters in sensitivity analyses showed effects on the ICERs without changing the overall trend of base-case results. When applying base-case results to the 2012 birthcohort in Germany with 80% vaccination coverage, an estimated 206,000-242,000 RV-cases and 18,000 RV-associated hospitalizations can be prevented in this birthcohort over five years for an incremental cost of 44.5-48.2 million €. CONCLUSION: Our analyses demonstrate that routine RV-vaccination could prevent a substantial number of RV-cases and hospitalizations in the German healthcare system, but the saved treatment costs are counteracted by costs for vaccination. However, with vaccine prices reduced by ∼62-66%, RV-vaccination could even become a cost-saving preventive measure.

Five types of OECD healthcare systems: empirical results of a deductive classification.

This article classifies 30 OECD healthcare systems according to a deductively generated typology by Rothgang and Wendt [1]. This typology distinguishes three core dimensions of the healthcare system: regulation, financing, and service provision, and three types of actors: state, societal, and private actors. We argue that there is a hierarchical relationship between the three dimensions, led by regulation, followed by financing and finally service provision, where the superior dimension restricts the nature of the subordinate dimensions. This hierarchy rule limits the number of theoretically plausible types to ten. To test our argument, we classify 30 OECD healthcare systems, mainly using OECD Health Data and WHO country reports. The classification results in five system types: the National Health Service, the National Health Insurance, the Social Health Insurance, the Etatist Social Health Insurance, and the Private Health System. All five types belong to the group of healthcare system types considered theoretically plausible. Merely Slovenia does not comply with our assumption of a hierarchy among dimensions and typical actors due to its singular transformation history.

Large scale study on measurement of respiration activity (AT(4)) by Sapromat and OxiTop.

In the run-up for amending the Austrian landfill ordinance, parameters were developed to assess the stability/reactivity of mechanically-biologically pretreated residual wastes. The Landfill Ordinance 2008 regulates limit values for Respiration Activity (="Atmungsaktivität") RA(4) (AT(4))<7mgO(2)*(g dry matter (DM))(-1), Gas Generation Sum GS(21)<20Nl*kgDM(-1) and alternatively Gas Evolution (="Gasbildung") GB(21)<20Nl*kgDM(-1). Methods for analysing these parameters were established by the Austrian Standards Institute (2004). As laboratory practice shows, these methods also are used for the assessment of other wastes (sewage sludge, commercial waste, material from abandoned sites, biowaste compost). For measurement of respiration activity in Austria mainly two methods are used: the Sapromat®-method and the OxiTop®-method. Whether respectively to what extent these two methods give same results, is discussed in this paper. Since 2009 at ABF-BOKU 169 respiration activity tests of samples taken from different stages of MBT - as well as biowaste composting processes, materials from landfills as well as abandoned sites and residues from anaerobic treatment plants were analysed parallel by Sapromat® and OxiTop®. The results manifest very strong correlation between the Sapromat® and OxiTop® method. The correlation coefficient is 0.993. As a very clear tendency OxiTop® gives lower amounts than Sapromat®. In average the lower values of OxiTop® are around 88%.
