In this work, we describe the complex formation and radiochemistry of the cyclen-based chelator DOTI-Me bearing four methylimidazole arms. Radiolabeling properties were evaluated for Mn, Cu, Ga, In, Tb, and Lu, and DOTI-Me showed distinct differences to the structurally related HDOTA. While radiochemical conversions (RCCs) for Mn and In were comparable to those of HDOTA, DOTI-Me was not suited for Ga.

The approval and effectiveness of immune checkpoint inhibitors in head-and-neck squamous cell carcinoma (HNSCC) highlights the role of the immune system in this tumor entity. HNSCCs not only interacts with the immune system in the tumor tissue, but also induce systemic effects that may be additionally influenced by further factors such as the microbiome. Nonetheless, reliable immunological biomarkers that predict treatment response and outcome in HNSCC patients are lacking.

Article Synopsis
  • Aortic regurgitation (AR) can develop in about one-third of LVAD patients over three years, potentially leading to heart failure.
  • The study followed 68 patients who had mild or no AR during HeartMate 3 implantation, with findings showing stable aortic root dimensions despite some patients developing AR.
  • Patient survival rates over five years were 71%, indicating that the development of AR did not significantly impact overall survival.

CD16+ as predictive marker for early relapse in aggressive B-NHL/DLBCL patients.

Mol Cancer

September 2024

Biophysics, Center for Integrative Physiology and Molecular Medicine (CIPMM), School of Medicine, Saarland University, Building 48, 66421, Homburg, Germany.

Assessing the prognosis of patients with aggressive non-Hodgkin B cell lymphoma mainly relies on a clinical risk score (IPI). Standard first-line therapies are based on a chemo-immunotherapy with rituximab, which mediates CD16-dependent antibody-dependent cellular cytotoxicity (ADCC). We phenotypically and functionally analyzed blood samples from 46 patients focusing on CD16+ NK cells, CD16+ T cells and CD16+ monocytes.

Background: Head and neck squamous cell carcinomas (HNSCCs) are among the six most common cancers, with a constantly poor prognosis. Vitamin D has been found to have antineoplastic and immunomodulatory properties in various cancers. This study investigated the impact of Vitamin D on the initiation and progression as well as antitumor immune response in HNSCCs, both in vitro and in vivo.

  • Early penetrating keratoplasty (PKP) for Acanthamoeba keratitis (AK) after conservative treatment (LLKP) may offer better visual outcomes than delayed PKP.
  • A study analyzed 28 patients who underwent LLKP, showing significant improvement in best corrected visual acuity (BCVA) and a low recurrence rate (4%) over an average follow-up of 53 months.
  • Results indicate that earlier PKP can lead to better visual and psychological recovery, prompting a reassessment of treatment timing for AK.

Background: Tumor-associated neutrophils (TANs) are important modulators of the tumor microenvironment with opposing functions that can promote and inhibit tumor progression. The prognostic role of TANs in early luminal breast cancer is unclear.

Methods: A total of 144 patients were treated for early-stage hormone-receptor-positive breast cancer as part of an Accelerated Partial Breast Irradiation (APBI) phase II trial.

PeCa is a rare entity with rising incidence rates due to increased infections with human papillomaviruses (HPV). The distinct subtypes of PeCa with an individual pathogenesis demand biomarkers for a precise patient risk assessment regarding disease progression and therapeutic susceptibility. We recently identified promising candidates associated with an HPV-instructed tumor microenvironment (TME) using HPV-positive PeCa cell lines and tissue microarrays (TMA).

The human microbiome emerges as a promising reservoir for diagnostic markers and therapeutics. Since host-associated microbiomes at various body sites differ and diseases do not occur in isolation, a comprehensive analysis strategy highlighting the full potential of microbiomes should include diverse specimen types and various diseases. To ensure robust data quality and comparability across specimen types and diseases, we employ standardized protocols to generate sequencing data from 1931 prospectively collected specimens, including from saliva, plaque, skin, throat, eye, and stool, with an average sequencing depth of 5.

Division of Gastroenterology and Hepatology, Medical University of Vienna, Vienna, Austria; Vienna Hepatic Hemodynamic Lab, Medical University of Vienna, Vienna, Austria; Department of Medicine III and Clinical Research Group Mechanisms in Portal Hypertension, Medical University of Vienna, Vienna, Austria. Electronic address:

Article Synopsis
  • Researchers aimed to evaluate spleen stiffness measurement (SSM) as a standalone non-invasive test for clinically significant portal hypertension (CSPH) in patients with compensated advanced chronic liver disease (cACLD) and compare it to the existing ANTICIPATE±NASH model.
  • The study involved 407 patients recruited from 16 expert centers in Europe, utilizing various non-invasive tests alongside hepatic venous pressure gradient measurements to assess CSPH probability.
  • The findings indicated the potential for SSM to enhance diagnostic capabilities, as models were created to evaluate its effectiveness and discriminative ability compared to existing methods using binary logistic regression analysis.

Cardio-ocular syndrome: Retinal microvascular changes in acutely decompensated heart failure.

Eur J Heart Fail

November 2024

Internal Medicine Clinic III, Cardiology, Angiology and Intensive Care Medicine, Saarland University Hospital, Homburg, Germany.

Aims: To investigate the changes in retinal microvasculature by contemporary imaging techniques during episodes of acute decompensated heart failure (ADHF) and following recompensation compared to age-matched controls without known cardiac or retinal disease.

Methods And Results: Adult patients hospitalized with a primary diagnosis of ADHF, regardless of left ventricular ejection fraction (LVEF) and treated with a minimum dose of 40 mg of intravenous furosemide or equivalent were included. Transthoracic echocardiography was conducted in all patients.

Neutrophils play a crucial role in the tumor microenvironment (TME) of head and neck squamous cell carcinomas (HNSCC) and significantly influence treatment outcomes. Phenotypic and functional properties of neutrophils adapt to the TME with distinct subsets modulating disease progression and therapeutic interventions. Here, we evaluated phenotypic and functional differences of neutrophils derived from HNSCC patients and healthy donors.

November 2024

Dr. Rolf M. Schwiete Center for Limbal Stem Cell and Congenital Aniridia Research, Saarland University, Kirrberger Str. 100, Homburg, Saarland, 66424, Germany.

Introduction: In congenital aniridia caused by mutations in paired box 6 (PAX6), PAX6 influences the migration and differentiation of limbal epithelial cells (LECs), thereby playing a pivotal role in aniridia-associated keratopathy. The antidepressants ritanserin and duloxetine affect PAX6 expression in LECs. Limbal stromal cells, which support limbal epithelial stem cells, are crucial in the limbal stem cell niche.

Dr. Rolf M. Schwiete Center for Limbal Stem Cell and Aniridia Research, Saarland University, Kirrberger Str. 100, 66424, Homburg/Saar, Germany.

Article Synopsis
  • - Aniridia-associated keratopathy is linked to a shortage of the PAX6 transcription factor, leading to increased oxidative stress and damaged proteins in the corneal epithelium of affected individuals.
  • - In a study comparing normal limbal fibroblast cells (LFCs) and LFCs from congenital aniridia patients, it was found that an increase in oxidative stress significantly affected gene and protein expression of antioxidant enzymes in aniridia LFCs.
  • - The results showed that aniridia LFCs have a heightened vulnerability to oxidative stress, with changes in expression levels of key enzymes, such as decreased Nrf2 and antioxidant enzymes like CAT, SOD1, and GPX1, in
