Limited data is available on the health-related quality of life (HRQoL) and symptoms of patients with chronic myeloid leukemia (CML) who are in treatment-free remission (TFR). We herein report HRQoL results from the EURO-SKI trial. Patients who had been on tyrosine kinase inhibitors (TKIs) therapy for at least 3 years and achieved MR4 for at least 1 year were enrolled from 11 European countries, and the EORTC QLQ-C30 and the FACIT-Fatigue questionnaires were used to assess HRQoL and fatigue respectively.

December 2024

Department for Clinical Science, Intervention and Technology (CLINTEC), Division of Radiology, Karolinska Institutet, Stockholm, Sweden; Medical Radiation Physics and Nuclear Medicine, Section for Nuclear Medicine, Karolinska University Hospital, Huddinge, Stockholm, Sweden. Electronic address:

Article Synopsis
  • The study focuses on developing a machine-learning model to predict anastomotic leakage (AL) after esophagectomy for esophageal cancer, as this complication poses significant risks post-surgery.
  • 471 patients' preoperative CT and clinical data were analyzed to create and test the model using an XGBoost algorithm, with performance metrics measured using ROC curves.
  • The model showed a noteworthy accuracy, achieving a 79.2% area under the curve, which can aid in identifying patients at risk of AL, particularly where clinical indicators suggest low probability.*

Article Synopsis
  • Central nervous system (CNS) involvement in multiple myeloma (MM) is rare, occurring in only 1.2% of patients, with a median age of 63 years and a median time to CNS development of 28 months.
  • High-risk factors such as abnormal lactate dehydrogenase (LDH), high-risk cytogenetics, and extramedullary involvement (EMI) are significantly more common in CNS-MM patients, with EMI being a strong predictor for developing CNS-MM.
  • Although overall survival for CNS-MM patients is poor (median of 4 months), treatment advancements post-2016 show promise, with those receiving modern therapies having a median survival of 12 months.

The AIDA randomized clinical trial found no significant difference in clinical failure or survival between colistin monotherapy and colistin-meropenem combination therapy in carbapenem-resistant Gram-negative infections. The aim of this reverse translational study was to integrate all individual preclinical and clinical pharmacokinetic-pharmacodynamic (PKPD) data from the AIDA trial in a pharmacometric framework to explore whether individualized predictions of bacterial burden were associated with the trial outcomes. The compiled dataset included for each of the 207 patients was (i) information on the infecting Acinetobacter baumannii isolate (minimum inhibitory concentration, checkerboard assay data, and fitness in a murine model), (ii) colistin plasma concentrations and colistin and meropenem dosing history, and (iii) disease scores and demographics.

Osteoanabolic agents are used as a first line treatment in patients at high fracture risk. The PTH receptor 1 (PTH1R) agonists teriparatide (TPTD) and abaloparatide (ABL) increase bone formation, bone mineral density (BMD), and bone strength by activating PTH receptors on osteoblasts. Romosozumab (ROMO), a humanized monoclonal antibody against sclerostin, dramatically but transiently stimulates bone formation and persistently reduces bone resorption.

  • Predominantly antibody deficiencies (PAD) are the most common type of immune problems in people, but it's not well-known how many people have them in Greece.
  • A study was done on 153 patients to learn more about these deficiencies, and they found different types of PAD among the patients.
  • The study showed that it often took a long time (about 9 years) for people to be diagnosed with PAD after they first noticed symptoms, and many of the patients had more serious health issues like infections and even cancer.

Pulmonary Hypertension in Sickle Cell Disease: Novel Findings of Gene Polymorphisms Related to Pathophysiology.

Int J Mol Sci

April 2024

Thalassemia and Sickle Cell Disease Unit, Center of Expertise in Rare Hematological Diseases (Hemoglobinopathies), Laikon General Hospital Member of EuroBlood NET, 16 Sevastoupoleos Str., 11526 Athens, Greece.

Pulmonary hypertension (PH) is a progressive and potentially fatal complication of sickle cell disease (SCD), affecting 6-10% of adult SCD patients. Various mechanisms and theories have been evaluated to explain the pathophysiology of this disease. However, questions remain, particularly regarding the clinical heterogeneity of the disease in terms of symptoms, complications, and survival.

Background/aim: Immediate and delayed breast reconstruction remains a controversial topic. Apart from the clinical outcomes that have to be considered, there is a discrepancy of opinions regarding the potential differences in quality of life. It is essential to clarify this issue, in order to contribute to the reconstruction of the decision-making process.

Article Synopsis
  • - The study investigates how the number of allergens a person is sensitized to (monosensitized vs polysensitized) affects the severity and variety of symptoms in patients with allergic rhinitis (AR).
  • - Results show that polysensitized patients reported more symptoms, especially itchy eyes and wheezing, compared to monosensitized patients, indicating that having multiple sensitivities leads to a greater symptom burden.
  • - The research concludes that greater sensitization correlates with a wider range of symptoms and suggests that different levels of sensitization may affect various organs in the body.

Connexins, a family of tetraspan membrane proteins forming intercellular channels localized in gap junctions, play a pivotal role at the different stages of tumor progression presenting both pro- and anti-tumorigenic effects. Considering the potential role of connexins as tumor suppressors through multiple channel-independent mechanisms, their loss of expression may be associated with tumorigenic activity, while it is hypothesized that connexins favor the clonal expansion of tumor cells and promote cell migration, invasion, and proliferation, affecting metastasis and chemoresistance in some cases. Hepatocellular carcinoma (HCC), characterized by unfavorable prognosis and limited responsiveness to current therapeutic strategies, has been linked to gap junction proteins as tumorigenic factors with prognostic value.

Defining predictive biomarkers for targeted therapies and optimizing anti-tumor immune response is a main challenge in ongoing investigations. Progastrin has been studied as a potential biomarker for detecting and diagnosing various malignancies, and its secretion has been associated with cell proliferation in the gastrointestinal tract that may promote tumorigenesis. Progastrin is a precursor molecule of gastrin, synthesized as pre-progastrin, converted to progastrin after cleavage, and transformed into amidated gastrin via biosynthetic intermediates.

Article Synopsis
  • A study evaluated the antibody response (AR) in 54 hematopoietic stem-cell transplantation (HSCT) recipients after receiving the BNT162b2 vaccine, showing an initial AR positivity rate of 80.8% at one month, which slightly decreased to 85.7% at three months.
  • Among the cohort, a significant number of participants achieved high antibody titers at both measurement points, but a noted decline in titers occurred from one month to three months post-vaccination.
  • Negative factors impacting AR included pre-treatment conditions like hypogammaglobulinemia and specific medications like anti-CD20 antibodies, suggesting HSCT patients can benefit from vaccination around six months post-transplant even in the

Article Synopsis
  • This study compares two surgical methods, Hartmann's procedure (HP) and resection with primary anastomosis (RPA), for treating acute left-sided colonic emergencies among 1215 patients from 204 centers globally.
  • Results showed that while HP was the more common treatment (57.3%), RPA was favored for younger patients with fewer health issues and those needing surgery sooner.
  • The study concluded that although HP is still widely used, RPA might be the better option, emphasizing the importance of patient characteristics and surgeon experience in determining treatment choice.
