The fires of life.

This retrospective recounts the hunt for the mechanism of mitochondrial ATP synthesis, the early days of research on mitochondrial formation, and some of the colorful personalities dominating these often dramatic and emotional efforts. The narrative is set against the backdrop of postwar Austria and Germany and the stream of young scientists who had to leave their countries to receive postdoctoral training abroad. Many of them--including the author--chose the laboratory of a scientist their country had expelled a few decades before. The article concludes with some thoughts on the uniqueness of U.S. research universities and a brief account of the struggles to revive science in Europe.

Pathway to Independence - an interview with Polina Kameneva.

Polina Kameneva is a postdoctoral researcher in the Adameyko group at the Medical University of Vienna, Austria, working at the interface between adrenal gland development and the origins of developmental cancers. Polina was selected as one of our first cohort of PI Fellows, a group of researchers who will be supported by Development's Pathway to Independence Programme as they aim to secure independent positions. We spoke to Polina to hear more about her career so far, why she decided to apply to the programme and what research questions she would like to address with her own group.

We caught up with Noelia over Zoom to find out more about her research and her transition to becoming an independent group leader.

Without a license, or accidents waiting to happen.

This is a memoir of circumstances that have shaped my life as a scientist, some of the questions that have excited my interest, and some of the people with whom I have shared that pursuit. I was introduced to transcription soon after the discovery of RNA polymerase and have been fascinated by questions relating to gene regulation since that time. My account touches on early experiments dealing with the ability of RNA polymerase to selectively transcribe its DNA template. Temporal programs of transcription that control the multiplication cycles of viruses (phages) and the precise mechanisms generating this regulation have been a continuing source of fascination and new challenges. A longtime interest in eukaryotic RNA polymerase III has centered on yeast and on the enumeration and properties of its transcription initiation factors, the architecture of its promoter complexes, and the mechanism of transcriptional initiation. These areas of research are widely regarded as separate, but to my thinking they have posed similar questions, and I have been unwilling or unable to abandon either one for the other. An additional interest in archaeal transcription can be seen as stemming naturally from this point of view.

Invasive Pulmonary Aspergillosis in Critically Ill Patients with Hantavirus Infection, Austria.

We investigated a cohort of 370 patients in Austria with hantavirus infections (7.8% ICU admission rate) and detected 2 cases (cumulative incidence 7%) of invasive pulmonary aspergillosis; 1 patient died. Hantavirus-associated pulmonary aspergillosis may complicate the course of critically ill patients who have hemorrhagic fever with renal syndrome.

Using liver stiffness to predict and monitor the risk of decompensation and mortality in patients with alcohol-related liver disease.

BACKGROUND & AIMS: Liver stiffness measurement (LSM) is recommended for disease prognostication and monitoring. We evaluated if LSM, using transient elastography, and LSM changes predict decompensation and mortality in patients with alcohol-related liver disease (ALD). METHODS: We performed an observational cohort study of compensated patients at risk of ALD from Denmark and Austria. We evaluated the risk of decompensation and all-cause mortality, stratified for compensated advanced chronic liver disease (cACLD: baseline LSM ≥10 kPa) and LSM changes after a median of 2 years. In patients with cACLD, we defined LSM changes as (A) LSM increase ≥20% ("cACLD increasers") and (B) follow-up LSM <10 kPa or <20 kPa with LSM decrease ≥20% ("cACLD decreasers"). In patients without cACLD, we defined follow-up LSM ≥10 kPa as an LSM increase ("No cACLD increasers"). The remaining patients were considered LSM stable. RESULTS: We followed 536 patients for 3,008 patient-years-median age 57 years (IQR 49-63), baseline LSM 8.1 kPa (IQR 4.9-21.7)-371 patients (69%) had follow-up LSM after a median of 25 months (IQR 17-38), 41 subsequently decompensated and 55 died. Of 125 with cACLD at baseline, 14% were "cACLD increasers" and 43% "cACLD decreasers", while 13% of patients without cACLD were "No cACLD increasers" (n = 33/246). Baseline LSM, follow-up LSM and LSM changes accurately predicted decompensation (C-index: baseline LSM 0.85; follow-up LSM 0.89; LSM changes 0.85) and mortality (C-index: baseline LSM 0.74; follow-up LSM 0.74; LSM changes 0.70). When compared to "cACLD decreasers", "cACLD increasers" had significantly lower decompensation-free survival and higher risks of decompensation (subdistribution hazard ratio 4.39, p = 0.004) and mortality (hazard ratio 3.22, p = 0.01). CONCLUSION: LSM by transient elastography predicts decompensation and all-cause mortality in patients with compensated ALD both at diagnosis and when used for monitoring. IMPACT AND IMPLICATIONS: Patients at risk of alcohol-related liver disease (ALD) are at significant risk of progressive disease and adverse outcomes. Monitoring is essential for optimal disease surveillance and patient guidance, but non-invasive monitoring tools are lacking. In this study we demonstrate that liver stiffness measurement (LSM), using transient elastography, and LSM changes after a median of 2 years, can predict decompensation and all-cause mortality in patients at risk of ALD with and without compensated advanced chronic liver disease. These findings are in line with results from non-alcoholic fatty liver disease, hepatitis C and primary sclerosing cholangitis, and support the clinical utility of LSM, using transient elastography, for disease prognostication and monitoring in chronic liver diseases including ALD, as recommended by the Baveno VII.

Cost-utility analysis of pharmacogenomics-guided tacrolimus treatment in Austrian kidney transplant recipients participating in the U-PGx PREPARE study.

Chronic kidney disease (CKD) is a global health issue. Kidney failure patients may undergo a kidney transplantation (KTX) and prescribed an immunosuppressant medication i.e., tacrolimus. Tacrolimus' efficacy and toxicity varies among patients. This study investigates the cost-utility of pharmacogenomics (PGx) guided tacrolimus treatment compared to the conventional approach in Austrian patients undergone KTX, participating in the PREPARE UPGx study. Treatment's effectiveness was determined by mean survival, and utility values were based on a Visual Analog Scale score. Incremental Cost-Effectiveness Ratio was also calculated. PGx-guided treatment arm was found to be cost-effective, resulting in reduced cost (3902 euros less), 6% less hospitalization days and lower risk of adverse drug events compared to the control arm. The PGx-guided arm showed a mean 0.900 QALYs (95% CI: 0.862-0.936) versus 0.851 QALYs (95% CI: 0.814-0.885) in the other arm. In conclusion, PGx-guided tacrolimus treatment represents a cost-saving option in the Austrian healthcare setting.

No evidence of asymptomatic monkeypox infection in a highly sexually active MSM population in Austria.

BACKGROUND: The 2022 outbreak of monkeypox virus (MPXV) revealed new transmission routes. Incidence declined sharply in September 2022, and it remains unclear whether MPXV is circulating in asymptomatic individuals because of increased immunity. OBJECTIVES: Our study aimed to assesss the number of asymtomatic MPXV carriers in individuals at high risk for STI. METHODS: We analysed anal samples from asymptomatic highly sexually active men who have sex with men for the presence of MPXV. RESULTS: We detected a high number of concomitant sexually transmitted infections but did not find a single sample with MPXV. CONCLUSIONS: Our results indicate that the general recommendation to implement screening for MPXV is not currently justified.

Effectiveness of a fourth SARS-CoV-2 vaccine dose in previously infected individuals from Austria.

INTRODUCTION: Evidence is limited on the effectiveness of a fourth vaccine dose against coronavirus disease 2019 (COVID-19) in populations with prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. We estimated the risk of COVID-19 deaths and SARS-CoV-2 infections according to vaccination status in previously infected individuals in Austria. METHODS: This is a nationwide retrospective observational study. We calculated age and gender adjusted Cox proportional hazard ratios (HRs) of COVID-19 deaths (primary outcome) and SARS-CoV-2 infections (secondary outcome) from 1 November to 31 December 2022, primarily comparing individuals with four versus three vaccine doses. Relative vaccine effectiveness (rVE) was calculated as (1-HR) X 100. RESULTS: Among 3,986,312 previously infected individuals, 281,291 (7,1%) had four and 1,545,242 (38.8%) had three vaccinations at baseline. We recorded 69 COVID-19 deaths and 89,056 SARS-CoV-2 infections. rVE for four versus three vaccine doses was -24% (95% CI: -120 to 30) against COVID-19 deaths, and 17% (95% CI: 14-19) against SARS-CoV-2 infections. This latter effect rapidly diminished over time and infection risk with four vaccinations was higher compared to less vaccinated individuals during extended follow-up until June 2023. Adjusted HR (95% CI) for all-cause mortality for four versus three vaccinations was 0.79 (0.74-0.85). DISCUSSION: In previously infected individuals, a fourth vaccination was not associated with COVID-19 death risk, but with transiently reduced risk of SARS-CoV-2 infections and reversal of this effect in longer follow-up. All-cause mortality data suggest healthy vaccinee bias.

Updated reference values for static lung volumes from a healthy population in Austria.

BACKGROUND: Reference values for lung volumes are necessary to identify and diagnose restrictive lung diseases and hyperinflation, but the values have to be validated in the relevant population. Our aim was to investigate the Global Lung Function Initiative (GLI) reference equations in a representative healthy Austrian population and create population-derived reference equations if poor fit was observed. METHODS: We analysed spirometry and body plethysmography data from 5371 respiratory healthy subjects (6-80 years) from the Austrian LEAD Study. Fit with the GLI equations was examined using z-scores and distributions within the limits of normality. LEAD reference equations were then created using the LMS method and the generalized additive model of location shape and scale package according to GLI models. RESULTS: Good fit, defined as mean z-scores between + 0.5 and -0.5,was not observed for the GLI static lung volume equations, with mean z-scores > 0.5 for residual volume (RV), RV/TLC (total lung capacity) and TLC in both sexes, and for expiratory reserve volume (ERV) and inspiratory capacity in females. Distribution within the limits of normality were shifted to the upper limit except for ERV. Population-derived reference equations from the LEAD cohort showed superior fit for lung volumes and provided reproducible results. CONCLUSION: GLI lung volume reference equations demonstrated a poor fit for our cohort, especially in females. Therefore a new set of Austrian reference equations for static lung volumes was developed, that can be applied to both children and adults (6-80 years of age).

Comprehensive genetic screening of early-onset dementia patients in an Austrian cohort-suggesting new disease-contributing genes.

Early-onset dementia (EOD), with symptom onset before age 65, has a strong genetic burden. Due to genetic and clinical overlaps between different types of dementia, whole-exome sequencing (WES) has emerged as an appropriate screening method for diagnostic testing and novel gene-finding approaches. We performed WES and C9orf72 repeat testing in 60 well-defined Austrian EOD patients. Seven patients (12%) carried likely disease-causing variants in monogenic genes, PSEN1, MAPT, APP, and GRN. Five patients (8%) were APOE4 homozygote carriers. Definite and possible risk variants were detected in the genes TREM2, SORL1, ABCA7 and TBK1. In an explorative approach, we cross-checked rare gene variants in our cohort with a curated neurodegeneration candidate gene list and identified DCTN1, MAPK8IP3, LRRK2, VPS13C and BACE1 as promising candidate genes. Conclusively, 12 cases (20%) carried variants relevant to patient counseling, comparable to previously reported studies, and can thus be considered genetically resolved. Reduced penetrance, oligogenic inheritance and not yet identified high-risk genes might explain the high number of unresolved cases. To address this issue, we provide complete genetic and phenotypic information (uploaded to the European Genome-phenome Archive), enabling other researchers to cross-check variants. Thereby, we hope to increase the chance of independently finding the same gene/variant-hit in other well-defined EOD patient cohorts, thus confirming new genetic risk variants or variant combinations.

Low incidence of tumor lysis syndrome in elderly patients with chronic lymphocytic leukemia treated with venetoclax under real-world conditions: results from the prospective observational VeRVe study.

Venetoclax is active in both frontline and relapsed/refractory settings for the treatment of chronic lymphocytic leukemia (CLL). Although the prevalence and severity of tumor lysis syndrome (TLS) are well characterized in clinical trials, laboratory and clinical TLS remain relatively unexplored in real-world clinical practice.In this prospective, real-world observational study, we aimed to determine the incidence and outcomes of TLS in patients with CLL receiving venetoclax outside a clinical trial. The study (VeRVe) was conducted in centers in Austria, Germany, and Switzerland.Two hundred and thirty-nine patients were treated according to local label with at least one dose of venetoclax. Patient demographics, baseline characteristics, and blood chemistry at baseline were documented, and descriptive statistical analyses were conducted.Seventy eight patients (33%) were treated with venetoclax monotherapy, 101 (42%) with venetoclax in combination with rituximab and 60 (25%) with venetoclax in combination with obinutuzumab. In all cases, the TLS risk mitigation strategy adhered to the ramp-up protocol. Median age was 73 years and 66% of patients were male. The majority of patients (75%) had relapsed/refractory CLL, 63/192 (32.8%) patients tested had a del(17p) and 93/134 (69.4%) patients tested had unmutated immunoglobulin heavy chain variable region gene (IGHV). Clinical TLS occurred in 5 patients (2.1%) and laboratory TLS occurred in 15 patients (6.3%). Ten patients received specific treatment, of which 6 were hospitalized. There were no deaths due to a TLS event and venetoclax was well-tolerated. Of the 5 clinical TLS events reported, none were fatal or resulted in renal failure (NCT03342144, registered on Nov 10, 2017).

Differences between men and women with respect to colorectal cancer mortality despite screening colonoscopy.

BACKGROUND AND AIMS: Women aged 55 to 59 years have a similar prevalence rate and number needed to screen for colorectal adenomas as men at a 10-year younger age. The aim of this study was to determine sex-specific differences in colorectal cancer mortality and estimate the association with adenomas at screening colonoscopy. METHODS: This retrospective study analyzed 323,139 individuals who underwent colonoscopy within a national colorectal cancer screening program in Austria between January 2007 and December 2020. RESULTS: Median patient age was 60 years (interquartile range, 54-67), and the sex distribution in all age groups was nearly identical. Men had significantly higher odds of having an adenoma or serrated polyp, low-risk polyp, high-risk polyp, or colorectal cancer detected at colonoscopy than women (odds ratio [OR] 1.83; 95% confidence interval [CI], 1.80-1.86; OR, 1.46; 95% CI, 1.44-1.49; OR, 1.74; 95% CI, 1.69-1.80; and OR, 1.87; 95% CI, 1.70-2.05, respectively). Strikingly, male sex, when compared with female sex, was associated with an almost 2-fold (hazard ratio, 1.67; 95% CI, 1.05-2.67) increased risk to die from colorectal cancer when an adenoma or serrated polyp was found at the screening colonoscopy and a 4-fold (hazard ratio, 4.14; 95% CI, 2.72-6.3) increased risk when a high-risk polyp was found at the screening colonoscopy. The cumulative incidence for death of colorectal cancer for 60-year-old individuals was 8.5-fold higher in men as compared with women. Markedly, this sex gap narrowed with increasing age, whereas the difference in deaths of other causes remained similar in all age groups. CONCLUSIONS: Our findings strengthen the necessity of sex-specific screening recommendations. Importantly, further prospective studies should focus on sex differences in tumor biology to propose personalized surveillance guidelines.

The landscape of penile cancer research in Germany and Austria: a survey among professors in academic centers holding chair positions and results of a literature search.

BACKGROUND: Research on penile cancer (PeCa) is predominantly conducted in countries with centralized treatment of PeCa-patients. In Germany and Austria (G + A), no state-regulated centralization is established, and no information is available on how PeCa-research is organized. METHODS: Current research competence in PeCa was assessed by a 36-item questionnaire sent to all chairholders of urological academic centers in G + A. Based on PubMed records, all scientific PeCa-articles of 2012-2022 from G + A were identified. Current research trends were assessed by dividing the literature search into two periods (P1: 2012-2017, P2: 2018-2022). A bibliometric analysis was supplemented. RESULTS: Response rate of the questionnaire was 75%, a median of 13 (IQR: 9-26) PeCa-patients/center was observed in 2021. Retrospective case series were conducted by 38.9% of participating clinics, while involvement in randomized-controlled trials was stated in 8.3% and in basic/fundamental research in 19.4%. 77.8% declared an interest in future multicenter projects. 205 PeCa-articles were identified [median impact factor: 2.77 (IQR: 0.90-4.37)]. Compared to P1, P2 showed a significant increase in the median annual publication count (29 (IQR: 13-17) vs. 15 (IQR: 19-29), p < 0.001), in multicenter studies (79.1% vs. 63.6%, p = 0.018), and in multinational studies (53% vs. 28.9%, p < 0.001); the proportion of basic/fundamental research articles significantly declined (16.5% vs. 28.9%, p = 0.041). Four of the top-5 institutions publishing PeCa-articles are academic centers. Bibliometric analyses revealed author networks, primary research areas in PeCa, and dominant journals for publications. CONCLUSIONS: Given the lack of centralization in G + A, this analysis highlights the need for research coordination within multicenter PeCa-projects. The decline in basic/fundamental research should be effectively addressed by the allocation of funded research projects.

Psychological Consequences of Chronic Ethnic Discrimination in Male Turkish Immigrants Living in Austria: A 30-Day Ambulatory Assessment Study.

BACKGROUND: Chronic ethnic discrimination may be associated with negative psychological consequences in ethnic minority groups. However, little is known about the impact of acute discriminatory events on people who experience chronic ethnic discrimination. PURPOSE: We examined the impact of chronic and acute ethnic discrimination on the daily lives of Turkish immigrants in Austria, a population often overlooked in discrimination research. METHODS: Ninety male Turkish immigrants living in Austria (60 experiencing chronic and 30 infrequent ethnic discrimination) reported discriminatory events in real time for 30 days. Additionally, subjective stress, reactivity to daily hassles, affect, and maladaptive coping were assessed daily. RESULTS: Participants experiencing chronic ethnic discrimination indicated higher daily values for stress, negative affect, reactivity to daily hassles, and anticipation and avoidance coping. Negative psychological states increased for all participants on days when discriminatory events occurred, but participants with chronic ethnic discrimination showed significantly stronger increases in maladaptive coping and reactivity to daily hassles, with the latter effect persisting until the next day. CONCLUSIONS: Our study is the first to demonstrate interaction effects of chronic and acute ethnic discrimination on psychological factors in daily life. The results may advance the understanding of the mechanisms that lead to health disparities in ethnic minority populations and may inform the development of targeted interventions.

This study investigated the impact of chronic and acute ethnic discrimination on the daily lives of Turkish immigrants in Austria, a population often overlooked in discrimination research. While it is established that experiences of ethnic discrimination are related to worse mental and physical health, the "how," that is, the underlying psychological mechanisms, remain incompletely understood. Ninety male Turkish immigrants took part in this study, with 60 experiencing ethnic discrimination on a regular basis. Over a 30-day period, we tracked their experiences of discrimination and their daily stress, emotional reactions, and coping strategies. We found that the participants with regular experiences of ethnic discrimination had higher stress levels and more negative emotions than the participants with fewer experiences of discrimination. In addition, they more strongly reacted to acute discriminatory events in their daily lives and had more problems coping with such events. They even were more stressed by daily hassles, which continued into the following day. These findings advance the understanding of the negative impact of ethnic discrimination on health disparities in ethnic minority populations and may inform the development of targeted interventions.

COVID-19 infection in patients with history of pediatric heart transplant in Germany, Austria, and Switzerland.

COVID-19 is a heterogenous infection-asymptomatic to fatal. While the course of pediatric COVID-19 infections is usually mild or even asymptomatic, individuals after adult heart transplantation are at high risk of a severe infection. We conducted a retrospective, multicenter survey of 16 pediatric heart transplant centers in Germany, Austria and Switzerland to evaluate the risk of a severe COVID-19 infection after pediatric heart transplantation between 02/2020 and 06/2021. Twenty-six subjects (11 male) with a median age of 9.77 years at time of transplantation and a median of 4.65 years after transplantation suffered from COVID-19 infection. The median age at time of COVID-10 infection was 17.20 years. Fourteen subjects had an asymptomatic COVID-19 infection. The most frequent symptoms were myalgia/fatigue (n = 6), cough (n = 5), rhinitis (n = 5), and loss of taste (n = 5). Only one subject showed dyspnea. Eleven individuals needed therapy in an outpatient setting, four subjects were hospitalized. One person needed oxygen supply, none of the subjects needed non-invasive or invasive mechanical ventilation. No specific signs for graft dysfunction were found by non-invasive testing. In pediatric heart transplant subjects, COVID-19 infection was mostly asymptomatic or mild. There were no SARS-CoV-2 associated myocardial dysfunction in heart transplant individuals.

Influence of various factors on the legal outcome of cases of child abuse-experiences gathered at an interdisciplinary forensic examination center in Vienna, Austria.

BACKGROUND AND OBJECTIVE: To improve the currently low conviction rate in cases of child abuse a forensic examination center for children and adolescents (FOKUS) was established in Vienna, Austria. Besides a state of the art treatment combined with forensic documentation, one of FOKUS' key goals is to identify potential areas for improvements within the process legal proceedings in cases of child abuse through constant scientific monitoring. The accompanying study at hand includes all patients referred to FOKUS within a two year timeframe (n = 233), monitoring their progression from first contact with the medical professionals from FOKUS to the end of criminal proceedings. A detailed analysis of case files was performed in those cases that were reported to the legal authorities by the clinicians of FOKUS (n = 87). Aim of the study is to investigate which factors contribute to the initiation of legal proceedings and a successful conviction. RESULTS: Multivariate logistic regression analyses showed that main proceedings were opened more often in cases where the offender was an adult (p < 0.001) or admitted his guilt (p < 0.001) and if digital traces were available (p = 0.001) or trial support (p = 0.024) present. Furthermore, the combined occurrence of medical documentation and victim disclosure was related to a higher probability of opening main trials. CONCLUSION: These findings underline how challenging the successful persecution of an offender in cases of child abuse is.

Lack of microbiological awareness on the ward as a key factor for inappropriate use of anti-infectives: results of a point prevalence study and user satisfaction survey in a large university hospital in Austria.

PURPOSE: Although diagnostic stewardship issues in clinical microbiology harbor an optimization potential for anti-infective consumption, they are only marginally addressed in antimicrobial stewardship (AMS) programs. As part of an AMS point prevalence (PPS) survey we therefore aimed to gain a more dynamic view on the microbiological awareness within therapeutic regimens. By examining whether initial microbiological sampling was performed and in which way microbiological results were incorporated into further treatment considerations we sought to find out to what extent these points determine the appropriateness of treatment regimens. METHODS: PPS was performed at the University Hospital Salzburg (1524 beds) in May 2021. Relevant data was determined from the patient charts and the appropriateness of anti-infective use was assessed using predefined quality indicators. Six months after the PPS, a questionnaire was administered to clinicians to obtain information on the use of microbiological findings and their relevance in the clinic. RESULTS: Lack of microbiological awareness in the clinical setting proved to be the key reason for an overall inadequate use of anti-infectives (35.4% of cases rated as inadequate), ahead of the aspects of dose (24.1%), empirical therapy (20.3%) and treatment duration (20.2%). This was particularly the case for broad-acting agents and was most evident in urinary tract infections, skin and soft tissue infections, and pneumonia. The results of the questionnaire indicate a discrepancy between the physicians surveyed and the routine clinical setting. CONCLUSION: A high potential in improving the use of anti-infectives in hospitals seems to lie in a strong emphasis on microbiological diagnostic stewardship measures.

Successful treatment of glandular tularemia with azithromycin in a pregnant woman in Austria.

Treatment of tularemia during pregnancy is challenging due to toxicity of standard treatment regimens. Here, we report a 31-year-old woman with glandular tularemia who was successfully treated with intravenous azithromycin. Follow-up examinations over a 6-month period showed a sustained response to treatment. She later gave birth to a healthy child.

Evaluation of the "Burgenland PREvention trial of colorectal cancer Disease with ImmunologiCal Testing" (B-PREDICT)-a population-based colorectal cancer screening program.

BACKGROUND: The colorectal cancer (CRC) screening program B-PREDICT is a population based invited two stage screening project using a faecal immunochemical test (FIT) for initial screening followed by a colonoscopy for those with a positive FIT. B-PREDICT was compared with the opportunistic screening colonoscopy (OPP-COL), performed in course of the nationwide screening program. METHODS: Within B-PREDICT all residents of the Austrian federal state Burgenland, aged between 40 and 80 are annually invited to FIT testing. All individuals who underwent initial colonoscopy in Burgenland between 01/2003 and 12/2014, were included in this study. Individuals from the FIT-triggered invited screening program B-PREDICT were compared with those from the non-FIT triggered OPP-COL. RESULTS: 15 133 individuals from B-PREDICT were compared to 10 045 individuals with OPP-COL. CRC detection rates were 1.34% (CI-95%, [1.15; 1.52]) in B-PREDICT compared to 0.54% in OPP-COL (95%-CI, [0.39; 0.68] p < 0.001). The decrease in the age standardized incidence rates of CRC was more pronounced in the population screened with FIT than in the general population screened with colonoscopy. Changes in incidence rates per year were -4.4% (95%-CI, [-5.1; -3.7]) vs. -1.8% (95%-CI, [-1.9; -1.6] p < 0.001). CONCLUSIONS: B-PREDICT shows a two-fold higher detection rate of CRC as well as HRA compared to OPP-COL.
