A retrospective, single-center analysis of 14 cases of Candida endocarditis (from 355 candidemia cases during the years 2012–2019) revealed a high in-hospital mortality (57.1%), a high proportion of healthcare-associated infections (13/14) and a high treatment preference for echinocandins. Transthoracic echocardiography and 18F-FDG PET/CT had a sensitivity of 54.5% and 57.1%, respectively. Patients were older than previously described and most patients with Candida endocarditis had persistent candidemia for ≥ 3 days despite antifungal therapy.

We present four cases with Gram-positive bacteremia (pathogens: MRSA n = 1, Enterococcus spp. n = 3) due to an intravascular source (left ventricular assist device: n = 2, transfemoral aortic valve implantation n = 1, prosthetic aortic valve: n = 1) where no curative treatment was available. These patients received indefinite, chronic suppressive (palliative) therapy with dalbavancin (500 mg weekly or 1000 mg biweekly regimens). Outcomes and clinical characteristics are described; treatment was effective in suppression of bacteremia in all patients over several months (range: 1 to more than 12 months), we observed no relevant side effects.

The aim of this study was to analyse temporal changes in the epidemiology of candidemia assessing patient’s characteristics, risk factors, diagnostic management, treatment, and outcome in a tertiary care hospital in South Eastern Germany. In this retrospective cohort study patients with blood cultures positive for Candida spp. were identified from the microbiological database in the years 2006–2018. A detailed collection of patients’ characteristics was obtained for the time periods 2006–2008 and 2016–2018. Risk factors for survival were analysed in a logistic regression analysis. In the years 2006–2018, a total of 465 episodes of candidemia were identified. An increase in candidemia cases was evident in the period of 2016–2018 compared to 2006–2015 and to 2006–2008 in absolute numbers and adjusted to patient-days. C. albicans was responsible for 62.8% of cases in 2006–2008 and 51.2% of all cases in the years 2016–2018, respectively, whereas there was a significant increase of C. glabrata in the latter period (16.3–31.5%). Overall mortality was not significantly different in the two periods. Infectious diseases consultation led to a lower mortality of patients with candidemia and to a higher adherence to guidelines. In multivariate analysis, only complete change or extraction of intravascular indwelling material and female gender were independent predictors for survival. We observed an increase in candidemia rates and rates of non-albicans spp. over time. A complete change of all catheters and/or indwelling devices improved survival. ID consultation led to a better guideline adherence.

Pneumocystis jirovecii pneumonia (PcP) has for many years been reported mostly in human immunodeficiency virus-infected patients. Increasingly, it also affects other immunocompromised patients, e.g. after organ or allogeneic stem cell/bone marrow transplantation, patients with hematologic malignancies or autoimmune diseases. The diagnosis of PcP relies on a critical evaluation of clinical symptoms, risk factors, radiologic features and microbiological tests. High dose cotrimoxazole is the most effective therapeutic option. Rapid initiation is essential, since mortality is especially high in patients admitted to intensive care with respiratory failure. This article reviews the current epidemiology of PcP and highlights the diagnostic and therapeutic options. Recommendations for primary and secondary prophylaxis are summarized.

Vaccinations are among the most effective preventative healthcare measures. The aim of this cross-sectional study was to evaluate the adherence of adults with pre-existing pulmonary conditions to the national vaccination schedule and to identify reasons for poor adherence. All patients with an appointment at Donaustauf hospital between October 2019 and April 2020 were asked to bring their vaccination certificates for evaluation and to compete a questionnaire. To determine the adherence vaccination certificates and patients’ comorbidities were correlated with the national recommendations of the German Standing Committee on Vaccination (STIKO). 571 (65.6%) of all patients believed that their vaccination status was up-to-date. An appropriate vaccination status according to national recommendations (STIKO) was documented as follows: tetanus 56.4% (375/665), diphtheria 43.2% (292/676), poliomyelitis 28.5% (189/662), tick-borne encephalitis 45.4% (300/659), hepatitis A 31.0% (18/58), hepatitis B 34.6% (27/78), shingles 1.2% (6/489), influenza 21.0% (125/596, season 2019/2020), measles 38.3% (31/81), rubella 33.3% (7/21), pneumococcal disease 29.5% (175/593), pertussis 54.2% (365/674) and haemophilus influenza type b 100% (1/1). Adherence to rabies (0/2), varicella (0/28), meningococcal type ACWY (0/36) and type b (0/36) was 0%. 72% of patients would follow a physician’s recommendation to get vaccinated. Adherence to STIKO recommendations was poor. However, patients are willing to follow a physician’s recommendation for vaccination.

Aims The objective of this study was to investigate the prognostic value of urinary N-terminal pro-brain natriuretic peptide (NT-proBNP) compared with plasma NT-proBNP in patients presenting with acute chest pain in the emergency department. Methods and results We measured simultaneously plasma and urinary NT-proBNP at admission in 301 patients with acute chest pain. In our cohort, 174 patients suffered from acute coronary syndrome (ACS). A follow-up (median of 55 months) was performed regarding the endpoints all-cause mortality and major adverse cardiac events (mortality, congestive heart failure, ACS with the necessity of a coronary intervention, and stroke). Fifty-four patients died during follow-up; 98 suffered from the combined endpoint. A significant and positive correlation of urinary and plasma NT-proBNP was found (r = 0.87, P < 0.05). Patients with troponin positive ACS had significantly elevated levels of plasma and urinary NT-proBNP compared with those with unstable angina pectoris or chest wall syndrome (each P < 0.05). The highest levels of both biomarkers were found in patients with congestive heart failure (each P < 0.05). According to Kaplan���Meier analysis, plasma and urinary NT-proBNP were significant predictors for mortality and the combined endpoint in the whole study cohort and in the subgroup of patients with ACS (each P < 0.05). Regarding Cox regression analysis, plasma and urinary NT-proBNP were independent predictors for mortality and the combined endpoint (each P < 0.05). Conclusions Urinary NT-proBNP seems to provide a significant predictive value regarding the endpoints all-cause mortality and major adverse cardiac events in patients with acute chest pain and those with ACS.

Coronavirus disease 2019 (Covid-19) vaccination is essential to fight the pandemic. Health care workers (HCWs) are prioritized to get vaccinated, yet uptake of recommended vaccinations is known to be low in this group. In a tertiary care university hospital with a high number of Covid-19 patients in intensive care, 59.5% of surveyed staff (N = 2454) were willing to get vaccinated, 21.4% were unsure and 18.7% refused. Vaccine hesitancy was higher in female, younger and healthy employees without contact to Covid-19 patients; nurses (53.3%) were much less willing to get vaccinated compared to physicians (82.7%).

Introduction The aim of this study was to analyse use of and adherence to influenza and pneumococcal vaccination in high-risk patients with chronic pulmonary disease. Methods The study was initiated at the Centre of Pneumology in Donaustauf, Germany. All patients with asthma bronchiale (AB), chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) that were treated in a pneumological Non-ICU ward, in the sleep laboratory or in the outpatient's clinic between October 1st, 2019 and March 26th, 2020 and provided informed consent were included. Vaccination certificates and a vaccination-centred questionnaire were analysed in relation to vaccination status, risk factors, patient characteristics. Results 133 patients with COPD, 68 patients with AB and 104 patients with ILD were included. PCV13/PPSV23 vaccination only (no sequential vaccination) was performed in less than 10%/33% of all patients. Sequential vaccination of PCV13 and PPSV23 was performed in 12.8% of COPD, 7.4% of AB patients and 13.5% of ILD patients. Influenza vaccination was performed in less than 30% of all patients. Vaccinations were mainly performed by general practitioners (GPs) and rarely by specialists of pulmonary care ( Discussion Use of and adherence for PPSV23 and influenza vaccinations is low in patients with COPD, AB and ILD in south east Germany.

Background We assessed the diagnostic value of FDG PET/CT in a real-world cohort of patients with surgically managed infective endocarditis (IE). Methods We performed a retrospective analysis of all patients hospitalized in a tertiary IE referral medical center from January 2014 to October 2018 fulfilling the following criteria: ICD-10 code for IE and OPS code for both, heart surgery and FDG PET/CT. Results Final analysis included 29 patients, whereof 28 patients had surgically proven IE. FDG PET/CT scan was true-positive in 15 patients (sensitivity (SEN) 56%) and false-negative in 12 patients. Combination of Duke criteria (DC) with FDG PET/CT scan resulted in gain of SEN for all patients with confirmed IE (SEN of DC 79% vs SEN of combination DC and FDG PET/CT 89%), driven by a relevant gain in PVE patients only (SEN of DC 78% vs SEN of combination DC and FDG PET/CT 94%). Interestingly, higher prosthesis age was observed in patients with false-negative scans. Conclusions We found a SEN of 56% for FDG PET/CT in a real-world cohort of patients with surgically proven IE which was associated with a 16% gain of IE diagnosis in patients with PVE when combined with DC.

Purpose: Aim of the present study was to investigate the sensitivity of high resolution ultrasound (HRU), standard contrast-enhanced ultrasound (CEUS) and CEUS using a novel vascular endothelial growth factor receptor 2 (VEGFR2)-targeted contrast agent for the detection of hepatic metastases in a mouse model of colorectal cancer using clinical standard technology. Materials and Methods: The human colon cancer cell line HT29, transfected with luciferase cDNA for in vivo bioluminescence monitoring, was injected intrasplenically into CB17.SCID mice. Mice were monitored weekly by bioluminescence and after 2 and 4.5 weeks by HRU and CEUS. Contrast media (untargeted BR1, targeted BR55) was applied and digital cine loops from the arterial phase (15 – 45 sec), portal venous phase (50 – 120 s) and late phases (3 – 5 min, 1hour) of the whole liver were analyzed. Data were correlated with postmortem histopathology. Results: Without contrast enhancement, lesions > 4 mm were reliably detected. After use of untargeted CEUS, lesions > 2 mm were reliably detected and enhanced rim vascularization and late-phase wash-out was shown. With BR55, lesions > 0.8 mm were reliably detected with excellent documentation of vascularization. A persistent contrast enhancement was seen > 30 min after injection. Contrast-enhancement patterns with BR55 significantly correlated with CD31 (R2 = 0.74) and VEGFR2-immunohistochemistry (R2 = 0.66). Conclusion: Detection of metastases by HRU and CEUS was earlier and more accurate than monitoring via bioluminescence. In vivo monitoring of hepatic micrometastases can thus be performed without prior modification of cancer cells using standard technology.

Abscesses and circumscribed collections of fluid are frequently found as complications of infectious diseases or surgery. Drainage is often indicated. We have established a new, economic, easy-to-make model to learn and improve competence in installing ultrasound-guided drainage. Up to fifteen water balloons (size 30 - 50 mm) were placed in a plastic box which then was filled with instant custard powder mixed with water. Spiral computed tomography (CT) of this box was performed. Experienced (n = 8) and inexperienced examiners (n = 8) drained the balloons via a direct puncture technique using either ultrasound-guidance alone or volume navigation with image fusion (ultrasound and CT) with needle tracking. Trainees filled out a questionnaire (before and after training) asking for information on their experience in ultrasound, in installing drainages and evaluating the new model. The time needed for installing the drainage was measured. None of the participants had ever attended a course on drainage installation. Only a few of the experienced examiners (n = 3) would autonomously install a drainage into a fluid collection with a size exceeding 4 cm before training. After training all participants felt more confident in ultrasound and in installing drainages into abscesses or other fluid collections. Most of the participants rated additional volume navigation with image fusion as a helpful tool. Ultrasound-guided drainage of abscesses can be trained easily with this new and economic model. Students and physicians can improve their skills and gain confidence in performing ultrasound-guided interventions.
