Intratumor heterogeneity of EGFR expression mediates targeted therapy resistance and formation of drug tolerant microenvironment.

Nat Commun

January 2025

Translational Immunology Research Program (TRIMM), Research Programs Unit, Faculty of Medicine, University of Helsinki, Helsinki, Finland.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors are commonly used to treat non-small cell lung cancers with EGFR mutations, but drug resistance often emerges. Intratumor heterogeneity is a known cause of targeted therapy resistance and is considered a major factor in treatment failure. This study identifies clones of EGFR-mutant non-small cell lung tumors expressing low levels of both wild-type and mutant EGFR protein.

One-year hemodynamic and clinical outcomes in self-expanding valves: Comparison of ACURATE neo2 versus ACURATE neo.

Cardiovasc Revasc Med

December 2024

Department of Cardiology and Catheterization Laboratories, Shonan Kamakura General Hospital, Okamoto 1370-1, Kamakura City, Kanagawa 247-8533, Japan. Electronic address:

Background/purpose: Transcatheter aortic valve replacement (TAVR) with ACURATE neo2 showed better hemodynamic outcomes by mitigating paravalvular leakage (PVL) compared with ACURATE neo, and revealed promising one-year outcomes in single-arm studies. However, studies comparing the hemodynamic and clinical outcomes of the two valves are still scarce. Therefore, this study aimed to compare the one-year hemodynamic and clinical outcomes between the neo2 and neo.

Background: Cardiac sarcoidosis involves a significant but difficult-to-define risk of sudden cardiac death (SCD). Current guidelines recommend consideration of an implantable cardioverter defibrillator for patients with extensive or significant myocardial late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging. However, extensive/significant LGE is not defined.

Understanding rare genetic variants within the terminal pathway of complement system in preeclampsia.

Genes Immun

December 2024

Translational Immunology Research Program, Research Programs Unit and Bacteriology and Immunology, University of Helsinki and Helsinki University Hospital, Helsinki, Finland.

Article Synopsis
  • Preeclampsia is a complex pregnancy-related disease linked to dysregulation of complement activation.
  • A study analyzed genetic variants in pregnant women, identifying specific mutations in the C5 and C6 genes that are associated with an increased risk or protection from preeclampsia.
  • These findings suggest that genetic factors in the complement system, particularly in the membrane attack complex, play a significant role in the development of preeclampsia.

Small intestinal neuroendocrine tumors (SI-NETs) are characterized by carcinoid syndrome and carcinoid heart disease (CHD). The aim of the present study was to identify early risk markers for carcinoid heart disease and survival in a prospective median-term follow-up setting. We measured 5-HIAA and cumulative 5-HIAA exposure (Cum-5-HIAA) based on repeated measurements, proBNP, vascular function, hepatic tumor load, and transthoracic echocardiography (TTE) at baseline and during the median 5-year follow-up.

Myasthenia gravis (MG) is a rare autoimmune disorder characterised by muscle weakness resulting from autoantibody-mediated disruption of the neuromuscular junction. Notably, it is also frequently associated with thymic pathology. This study explores the relationship between MG and DNA viruses in the thymus, employing targeted NGS and qPCR to analyse thymic tissue samples from both MG patients and healthy controls.

SPARCL1 and NT-proBNP as biomarkers of right ventricular-to-pulmonary artery uncoupling in pulmonary hypertension.

ESC Heart Fail

December 2024

Department of Internal Medicine, Justus-Liebig-University Giessen, Universities of Giessen and Marburg Lung Center (UGMLC), Institute for Lung Health (ILH), Cardio-Pulmonary Institute (CPI), Member of the German Center for Lung Research (DZL), Giessen, Germany.

Aims: SPARCL1 was recently identified as a biomarker of right ventricular (RV) maladaptation in patients with pulmonary hypertension (PH), and N-terminal pro-brain natriuretic protein (NT-proBNP) is an established biomarker of RV failure in PH. The present study investigated whether NT-proBNP and SPARCL1 concentrations are associated with load-independent parameters of RV function and RV-to-pulmonary artery (RV-PA) coupling as measured using invasive pressure-volume (PV) loops in the RV.

Methods: SPARCL1 and NT-proBNP were measured in the plasma of patients with idiopathic pulmonary artery hypertension (IPAH, n = 73).

Article Synopsis
  • Factor Xa inhibitors are commonly used to treat venous thromboembolism (VTE), but a small percentage of patients experience treatment failure, prompting this study to explore the causes of recurrent VTE in those receiving FXaIs.
  • The study included ten patients, mostly young adults with significant underlying VTE risk factors despite initial assessments suggesting unprovoked VTE, highlighting conditions like thoracic outlet syndrome contributing to their risks.
  • Results indicated that treatment failure occurred within a few months, often leading to serious complications like chronic thromboembolic pulmonary hypertension, and emphasized the importance of tailored treatment strategies and careful risk evaluation for patients with recurrent VTE.

Objective: Although the incidence and case fatality (CF) of acute myocardial ischaemic syndrome (AMIS) have declined in recent decades, some studies have suggested a potential stagnation in this decline. We examined if a similar development in AMIS trends can be observed in Finland from 1996 to 2021 among persons aged 35-74 years.

Methods: We linked Finnish country-wide Hospital Discharge- and Causes of Death- Registers covering the first non-fatal and fatal myocardial ischaemic events (total 69 906 442 person-years at risk).

JBMR Plus

December 2024

Endocrinology, Abdominal Center, Helsinki University Hospital and University of Helsinki, ENDO-ERN (European Reference Network on Rare Endocrine Conditions), FIN-00290 Helsinki, Finland.

Primary hyperparathyroidism (PHPT) associated with multiple endocrine neoplasia type 1 (MEN1) impairs bone mineral density and causes osteoporosis already in young patients. We aimed to investigate bone mineral density (BMD) in a contemporary cohort of patients with MEN1-related PHPT after long-term follow-up and compare these results with that of healthy controls. Thirty-five patients with genetically confirmed MEN1 were diagnosed with MEN1 at mean age 28.
