    Abstract A general study of biogeochemical processes (DYNAPROC cruise) was conducted in May 1995 at a time-series station in the open northwestern Mediterranean Sea where horizontal advection was weak. Short-term variations of the vertical distributions of pico- and nanophytoplankton were investigated over four 36-h cycles, along with parallel determinations of metabolic CO2 production rates and amino acid-containing colloid (AACC) concentrations at the chlorophyll maximum depth. The vertical (0-1000-m depth) distributions of (i) AACC, (ii) suspended particles and (iii) metabolic CO2 production rate were documented during the initial and final stages of these 36-h cycles. This study was concerned with diel vertical migration (DVM) of zooplankton, which provided periodic perturbations. Accordingly, the time scale of the experimental work varied from a few hours to a few days.
    Although all distributions exhibited a periodic behaviour, AACC distributions were generally not linked to diel vertical migrations. In the subsurface layer, Synechococcus made the most abundant population and large variations in concentration were observed both at day and at night. The corresponding integrated (over the upper 90 m) losses of Synechococcus during one night pointed to a potential source of exported organic matter amounting to 534 mg C/m**2. This study stresses the potential importance of organic matter export from the euphotic zone through the daily grazing activity of vertically migrating organisms, which would not be accounted for by measurements at longer time scales.
    The metabolic CO2 production exhibited a peak of activity below 500 m that was shifted downward, apparently in a recurrent way and independently of the vertical distributions of AACC or of suspended particulate material. To account for this phenomenon, a ?sustained wave train? hypothesis is proposed that combines the effect of the diel superficial faecal pellet production by swarming migrators and the repackaging activity of the nonmigrating midwater populations. Our results confirm the recent finding that the particulate compartment is not the major source of the observed instantaneous remineralisation rate and shed a new light on the fate of organic matter in the aphotic zone.

    Abstract Cardiovascular diseases and cancer are the most common causes of death in Germany. Cancer treatment can lead to significant cardiovascular side effects and thus form a link between the two disease groups. The focus of cardio-oncology is on the best possible prevention, diagnostics and treatment of cardiovascular complications caused by cancer treatment. It is crucial for cardio-oncology to adapt to the continuous development of new forms of oncological treatment with previously unknown cardiovascular side effects. One such new form of treatment is immune checkpoint inhibitor (ICI) therapy, which is regarded as the most important oncological milestone of the last decade due to its excellent oncological efficacy; however, the growing use has revealed a high risk of diverse cardiovascular side effects with high morbidity and mortality, so that cardio-oncological care of affected patients is of particular importance. This review summarizes the current scientific and clinical state of the pathophysiology, incidence, diagnosis and treatment of cardiovascular side effects of ICI therapy.

    Title translation Heart and cancer: cardio-oncology.
    Abstract Cardiovascular diseases and cancer have a complex relationship and show a reciprocal linkage and influence. Mutual risk factors, demographic changes and increasing multimorbidity result in an increase in the incidence of both diseases. Advances in oncological and cardiological treatment lead to a further increase in patients with cured or chronic diseases as a relevant comorbidity. The induction of cardiovascular side effects by cancer therapies leads to increased cardiovascular morbidity and mortality in cancer patients. Recent data also show that cardiovascular disease, through various factors, can also promote the development and progression of cancer. An understanding of the interrelationship between cardiovascular diseases and cancer can be seen as a major medical challenge for the future. To this end, scientific, structural, clinical and educational interfaces between cardiology and oncology are essential. This article outlines the complex relationships between cardiovascular diseases and cancer and defines current and future challenges for the best possible care of affected patients.

    Abstract Purpose of review: Immune checkpoint inhibitor (ICI) therapy has emerged as a pivotal advancement in cancer treatment, but the widespread adoption has given rise to a growing number of reports detailing significant cardiovascular toxicity. This review concentrates on elucidating the mechanisms behind ICI-related cardiovascular complications, emphasizing preclinical and mechanistic data.
    Recent findings: Accumulating evidence indicates a more significant role of immune checkpoints in maintaining cardiac integrity than previously understood, and new key scientific data are available to improve our understanding of ICI-related cardiovascular toxicity, including hidden cardiotoxicity. New avenues for innovative concepts are hypothesized, and opportunities to leverage the knowledge from ICI-therapy for pioneering approaches in related scientific domains can be derived from the latest scientific projects. Cardiotoxicity from ICI therapy is a paramount challenge for cardio-oncology. Understanding the underlying effects builds the foundation for tailored cardioprotective approaches in the growing collective at risk for severe cardiovascular complications.

    Abstract Drug-induced cardiovascular side effects have a significant impact on morbidity and mortality. The demographic change and improved long-term survival particularly in cancer patients have caused an increasing number of affected patients, hence emphasizing the importance of the best possible treatment of such complications. This article gives an overview of classic and modern groups of substances with cardiotoxic effects and summarizes the principles of diagnostics and therapy. After characterizing the common cardiovascular side effects caused by anthracycline chemotherapy, we focus on complications caused by modern forms of immunotherapy, considering its significant impact on oncological therapy in the future due to its growing clinical application. In addition to specific cancer therapies, accompanying measures such as blood transfusions in patients with hematologic diseases can also lead to severe cardiovascular complications. In the last section, we classify important features and therapeutic approaches in cardiac involvement of transfusion-related hemochromatosis. A good knowledge of the characteristics of specific cardiovascular side effects can help to improve the management of affected patients.

    Abstract Purpose of review: Cardiac amyloidosis (CA) constitutes an important etiology of heart failure with preserved ejection fraction (HFpEF) or heart failure with mildly reduced ejection fraction (HFmrEF). Since patients with CA show early exhaustion, we aimed to investigate whether non-exertional variables of cardiopulmonary exercise testing (CPET) provide additional information in comparison to traditional peak oxygen consumption (VO
    Recent findings: We retrospectively investigated CPET variables of patients with HFpEF and HFmrEF with (n = 21) and without (n = 21, HF) CA at comparable age and ejection fraction. Exertional and non-exertional CPET variables as well as laboratory and echocardiographic markers were analyzed. The primary outcome was the difference in CPET variables between groups. The secondary outcome was rehospitalization in patients with CA during a follow-up of 24 months. Correlations between CPET, NTproBNP, and echocardiographic variables were calculated to detect patterns of discrimination between the groups. HF patients with CA were inferior to controls in most exertional and non-exertional CPET variables. Patients with CA were hospitalized more often (p = 0.002), and rehospitalization was associated with VE/VCO

    Abstract Introduction: Preterm infants are at risk for a variety of somatic and neurological disorders. In recent years, biofluid proteomics has emerged as a potential diagnostic tool for biomarker analysis. The aim of this study was to determine gestational age (GA)-related patterns of the urinary peptidome in preterm infants for researching potential novel prognostic biomarkers.
    Methods: We performed urinary peptidomics in longitudinal samples of 24 preterm (mean GA weeks 28 + 1 [24+1-31 + 6]) and 27 term born controls (mean GA weeks 39 + 2 [37+0-41 + 1]) using capillary electrophoresis combined with mass spectrometry (CE-MS). Peptides were sequenced using CE-MS/MS or LC-MS/MS analysis and were deposited, matched, and annotated in a Microsoft SQL database for statistical analysis. We compared their abundance in urine of preterm and term born infants and performed a validation analysis as well as correlations to GA and clinical risk scores.
    Results: Our results confirmed significant differences in the abundance of peptides and the hypothesis of age-dependent urinary peptidome changes in preterm and term infants. In preterm infants, SLC38A10 (solute carrier family 38 member 10) is one of the most abundant peptides. Combined urinary peptides correlated with clinical risk scores (p < 0.05).
    Conclusion: This is the first study reporting GA-related urinary peptidome changes of preterm infants detected by CE-MS and a modulation of the peptidome with GA. Further research is required to locate peptidome clusters correlated with specific clinical complications and long-term outcome. This may identify preterm infants at higher risk for adverse outcome who would benefit from early intervention.
