PURPOSE Despite undergoing allogeneic hematopoietic stem cell transplantation (HCT), patients with acute myeloid leukemia (AML) with internal tandem duplication mutation in the FMS-like tyrosine kinase 3 gene ( FLT3-ITD) have a poor prognosis, frequently relapse, and die as a result of AML. It is currently unknown whether a maintenance therapy using FLT3 inhibitors, such as the multitargeted tyrosine kinase inhibitor sorafenib, improves outcome after HCT. PATIENTS AND METHODS In a randomized, placebo-controlled, double-blind phase II trial (SORMAIN; German Clinical Trials Register: DRKS00000591), 83 adult patients with FLT3-ITD–positive AML in complete hematologic remission after HCT were randomly assigned to receive for 24 months either the multitargeted and FLT3-kinase inhibitor sorafenib (n = 43) or placebo (n = 40 placebo). Relapse-free survival (RFS) was the primary endpoint of this trial. Relapse was defined as relapse or death, whatever occurred first. RESULTS With a median follow-up of 41.8 months, the hazard ratio (HR) for relapse or death in the sorafenib group versus placebo group was 0.39 (95% CI, 0.18 to 0.85; log-rank P = .013). The 24-month RFS probability was 53.3% (95% CI, 0.36 to 0.68) with placebo versus 85.0% (95% CI, 0.70 to 0.93) with sorafenib (HR, 0.256; 95% CI, 0.10 to 0.65; log-rank P = .002). Exploratory data show that patients with undetectable minimal residual disease (MRD) before HCT and those with detectable MRD after HCT derive the strongest benefit from sorafenib. CONCLUSION Sorafenib maintenance therapy reduces the risk of relapse and death after HCT for FLT3-ITD–positive AML.

Detailed pathophysiological manifestations of early disease in the context of prediabetes are poorly understood. This study aimed to evaluate the extent of early signs of metabolic and cardio-cerebrovascular complications affecting multiple organs in individuals with prediabetes. Subjects without a history of stroke, coronary artery disease, or peripheral artery disease were enrolled in a case-control study nested within the Cooperative Health Research in the Region of Augsburg (KORA) FF4 cohort and underwent comprehensive MRI assessment to characterize cerebral parameters (white matter lesions, microbleeds), cardiovascular parameters (carotid plaque, left ventricular function, and myocardial late gadolinium enhancement [LGE]), and metabolic parameters (hepatic proton-density fat fraction [PDFF] and subcutaneous and visceral abdominal fat). Among 400 subjects who underwent MRI, 103 subjects had prediabetes and 54 had established diabetes. Subjects with prediabetes had an increased risk for carotid plaque and adverse functional cardiac parameters, including reduced early diastolic filling rates as well as a higher prevalence of LGE compared with healthy control subjects. In addition, people with prediabetes had significantly elevated levels of PDFF and total and visceral fat. Thus, subjects with prediabetes show early signs of subclinical disease that include vascular, cardiac, and metabolic changes, as measured by whole-body MRI after adjusting for cardiometabolic risk factors.

he very first case of COVID-19 in Germany was detected on 27 January 2020 (1). The German health authorities isolated the first cases and traced and tested their contacts, but by mid-March 2020 community spread had become apparent in many regions. Testing capacities and dedicated medical care structures were set up to limit the spread and safeguard care of the general population. Within 2 weeks, nationwide countermeasures were introduced for a 6-week period. The goal was to contain the short-and long-term health impact of infection. However, concerns were raised regarding potential health consequences due to social isolation, increased stress and negative socioeconomic effects.Large population-based cohort studies offer the opportunity to study emerging new diseases and their effects on health. Thus, they are ideal for measuring the spread of COVID-19 in the general population (2) and to evaluate the health impacts of protective measures (3). In the study presented here we analyzed data on more than 100 000 individuals from the German National Cohort (NAKO) (4). The following parameters were considered:• Regional differences in COVID-19 occurrence among NAKO participants in comparison with the official statistics in spring 2020• The frequency of COVID-19-associated symptoms • Changes in mental health and self-rated general health status compared with a baseline assessment 1 to 5 years earlier. MethodsBetween 2014 and 2019, the NAKO recruited 205 219 randomly selected persons aged 20 to 74 years for the baseline examination at 18 study centers (4). Approval had been given by all study centers' local ethics committees, and all participants had provided written consent for study participation and repeat contact. The first follow-up examination started in 2019, but had to be halted in mid-March 2020 because of the COVID-19 pandemic and the Germany-wide protective countermeasures. Within a short time a new COVID-NAKO questionnaire was developed to collect information on SARS-CoV-2 tests and COVID-19-related symptoms and psychosocial factors. Further details can be found in eBox 1. The findings reported here rest on data SummaryBackground: The pandemic caused by the coronavirus SARS-CoV-2 and the countermeasures taken to protect the public are having a substantial effect on the health of the population. In Germany, nationwide protective measures to halt the spread of the virus were implemented in mid-March for 6 weeks.Methods: In May, the impact of the pandemic was assessed in the German National Cohort (NAKO). A total of 113 928 men and women aged 20 to 74 years at the time of the baseline examination conducted 1 to 5 years earlier (53%) answered, within a 30-day period, a follow-up questionnaire on SARS-CoV-2 test status, COVID-19associated symptoms, and self-perceived health status.Results: The self-reported SARS-CoV-2 test frequency among the probands was 4.6%, and 344 participants (0.3%) reported a positive test result. Depressive and anxiety-related symptoms increased relative to baseline only in participants und...

Introduction: Most patients with FLT3-ITD-positive AML, who relapse after allogenic stem cell transplantation (allo-SCT) die from their disease. Whether prophylactic FLT3-ITD inhibition with sorafenib can prevent AML relapse and improve outcome of patients in complete hematological remission (CHR) after allo-SCT is unknown and was tested in the SORMAIN trial. Methods: This randomized, double blind, placebo-controlled study was done at 14 centers in Germany and Austria. Patients with FLT3-ITD+ AML, aged 18 years or older, who had undergone allogenic stem cell transplantation from a HLA-matched sibling donor, 10/10 or 9/10 HLA-matched unrelated donor, and who were in confirmed CHR at the time of screening between day +30 and day +100 post allo-SCT, were included. Patients were randomly assigned (1:1) to receive either sorafenib (starting dose: 2 x 1 tbl. [2 x 200mg] qd, increasing every 14d to up to 2 x 2 tbl. [2 x 400mg] qd according to tolerability) or placebo (2 x 1 or 2 tbl. qd) for up to 24 months. Randomization was done centrally. In case of drug related adverse events, study medication could be interrupted, stepwise reduced to a minimum of 2 x 1 tbl. qd, temporarily withheld and recommenced at a lower dose level. FLT3-ITD diagnostics was done centrally at baseline and at time of relapse. In relapsing patients, off-label compassionate use of sorafenib was possible. The primary endpoint was relapse-free survival (RFS) as defined by either hematological relapse or death from any cause. The secondary endpoint was overall survival (OS). We here report the final RFS analysis. The OS results will be unblinded only prior to the ASH meeting and will be reported there. The SORMAIN study was terminated prior to full recruitment because of slow accrual. SORMAIN was registered with the European Clinical Trials Database (EudraCT 2010-018539-16) and the German Clinical Trials Register (DRKS00000591). Results: Between October 29, 2010, and May 17, 2016, 83 patients (41 males, 42 females) were randomized and included in the primary analysis (placebo, n=40; sorafenib, n=43). Median age was 54 years (IQR 47.75 - 61.33) for the entire study population and not significantly different between sorafenib and placebo groups. With a median follow up of 41.8 months after randomization (IQR 24.1 - 42.5), median RFS was 30.9 months (lower bound of 95% CI 5.2 months) in the placebo group versus not reached in the sorafenib group, corresponding to a 2-year RFS of 53,3 % (95% CI 36.5-67.5) in the placebo versus 85.0 % (69.5-93.0) in the sorafenib group (hazard ratio [HR] 0.39, 95% CI; 0.18 -0.85; P=0.0135) (Fig. 1). Overall, sorafenib was well tolerated. The most common grade 3-4 adverse event in both groups was acute GvHD (seven [ 17.5%] in the placebo group vs. nine [20.9%] in the sorafenib group. Conclusion: Sorafenib maintenance therapy after allo-SCT is feasible and significantly reduces the risk of relapse or death in patients with FLT3-ITD positive AML. OS results will be presented at the meeting. Figure 1. Figure 1.

Screening programs are recommended for individuals at risk (IAR) from families with familial pancreatic cancer (FPC). However, reliable imaging methods or biomarkers for early diagnosis of pancreatic ductal adenocarcinoma (PC) or its precursor lesions are still lacking. The ability of circulating microRNAs (miRNAs) to discriminate multifocal high-grade precursor lesions or PC from normal was examined. The presence of miRNA-21, -155, -196a, -196b and -210 was analyzed in the serum of transgenic KPC mice to test their ability to distinguish mice with different grades of pancreatic intraepithelial neoplasia (mPanIN1–3) or PC from control mice. Serum levels of miR-196a and -196b were significantly higher in mice with PanIN2/3 lesions (n = 10) or PC (n = 8) as compared to control mice (n = 10) or mice with PanIN1 lesions (n = 10; P = .01). In humans, miR-196a and -196b were also diagnostic. Patients with PC, sporadic (n = 9) or hereditary (n = 10), and IAR with multifocal PanIN2/3 lesions (n = 5) had significantly higher serum levels than patients with neuroendocrine pancreatic tumors (n = 10) or chronic pancreatitis (n = 10), IAR with PanIN1 or no PanIN lesions (n = 5), and healthy controls (n = 10). The combination of both miR-196a and -196b reached a sensitivity of 1 and specificity of 0.9 (area under the curve = 0.99) to diagnose PC or high-grade PanIN lesions. In addition, preoperative elevated serum levels of miR-196a and -196b in patients with PC or multifocal PanIN2/3 lesions dropped to normal after potential curative resection. The combination of miR-196a and -196b may be a promising biomarker test for the screening of IAR for FPC.

BackgroundMortality attributable to heart failure remains high. The prevalence of heart failure in patients with diabetes mellitus ranges from 19 to 26%. It is estimated that up to 21.1 million adults in the United States have diagnosed diabetes mellitus and around 80.8 million have impaired fasting glucose. We investigated the associations of fasting glucose (FG) and fasting insulin (FI), the homeostasis model assessment-insulin resistance index (HOMA-IR) and 2-h postload glucose (2HG) and insulin (2HI) with parameters of left ventricular geometry and function and arterial stiffness determined by magnetic resonance imaging in individuals without diagnosed type 2 diabetes.MethodsCross-sectional analyses of 1001 individuals (453 women, 45.3%), aged 21 to 80 years, from two independent population-based studies, the Study of Health in Pomerania (SHIP-TREND-0) and KORA FF4 Study. FG, FI, HOMA-IR, 2HG and 2HI, as well as glucose tolerance categories, were analyzed for associations with heart and arterial parameters using multivariable-adjusted linear regression models.ResultsIn total, 390 individuals (39%) had prediabetes (isolated impaired fasting glucose, isolated glucose tolerance or both), and 49 (4.9%) were found to have unknown type 2 diabetes. In the multivariable-adjusted analysis, positive linear associations of FG, FI, HOMA-IR, 2HG and 2HI with arterial stiffness index and left ventricular wall-thickness and concentricity and inverse linear associations with left ventricular end-diastolic volume were observed. A 1 mmol/l higher FG was associated with a 1.18 ml/m2.7 (1.80 to 0.57; p < 0.001) lower left ventricular end-diastolic volume index, a 0.042 mm/m2.7 (0.014 to 0.070) higher left ventricular wall-thickness index, a 0.12 mmHg m2.7/ml (0.06 to 0.17; p < 0.001) greater arterial stiffness index and a 0.037 g/ml (0.018 to 0.056; p < 0.001) higher left ventricular concentricity.ConclusionsOur findings suggest that higher glucose levels in the prediabetic range and insulin resistance might lead to higher arterial stiffness and concentric remodeling of the heart.

High-risk individuals of familial pancreatic cancer (FPC) families are considered to be good candidates for screening programs to detect early PC or its high-grade precursor lesions, especially pancreatic intraepithelial neoplasia (PanIN) 2/3 lesions. There is a definite need for diagnostic markers as neither reliable imaging methods nor biomarkers are available to detect these lesions. On the basis of a literature search, the potential serum markers neutrophil gelatinase-associated lipocalin (LCN2), metallopeptidase inhibitor 1 (TIMP1), chemokine (C-X-C motif) ligand 16 (CXCL16), IGFBP4, and iC3a, which were first tested in transgenic KrasLSL.(G12D/+);p53(R172H/+);Pdx1-Cre mice, were identified. ELISA analyses of LCN2, TIMP1, and CXCL16 revealed significantly higher levels in mice with PanIN2/3 lesions or PC compared to mice with normal pancreata or PanIN1 lesions. Analysis of preoperative human serum samples from patients with sporadic PC (n = 61), hereditary PC (n = 24), chronic pancreatitis (n = 28), pancreatic neuroendocrine tumors (n = 11), and FPC patients with histologically proven multifocal PanIN2/3 lesions (n = 3), as well as healthy control subjects (n = 20), confirmed significantly higher serum levels of LCN2 and TIMP1 in patients with PC and multifocal PanIN2/3 lesions. The combination of LCN2 and TIMP1 as a diagnostic test for the detection of PC had a sensitivity, specificity, and positive predictive value of 100% each. Although this preliminary finding needs to be validated in a large series of individuals at high risk for FPC, serum measurement of LCN2 and TIMP1 might be a promising screening tool.
