Plasmacytoid dendritic cell content is associated with plasma aldosterone concentration in patients with primary aldosteronism.

Background: Inflammation plays a pivotal role in blood pressure regulation. Current data reflect the important role of T cells in primary hypertension. The role of dendritic cells (DC) in secondary hypertension- primary aldosteronism (PA) remains unknown.

Characteristics and Outcomes of Pulmonary Embolism Patients Transferred After Activation of Pulmonary Embolism Response Team and Admitted from Local Emergency Department.

The primary role of a pulmonary embolism response team (PERT) is to support decision-making processes regarding acute pulmonary embolism (PE) patients and provide advanced rescue therapies when needed. Despite a great need for its availability among physicians, PERT's usefulness is yet to be proven. : Our goal was to establish whether patients benefit from qualification by PERT for admission to a tertiary cardiology ward.

Novel Insight into Inflammatory Pathways in Acute Pulmonary Embolism in Humans.

Accumulating data have shown a pathophysiological association between inflammatory pathways and thrombosis. Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and acute pulmonary embolism (APE), is a significant health burden. It involves not only hemodynamic disturbances due to the emboli occluding the pulmonary arteries, but also platelet activation, endothelial dysfunction, and "firing up" of the inflammatory cascade.

Acute Pulmonary Embolism and Immunity in Animal Models.

Venous thromboembolism, encompassing acute pulmonary embolism (APE) and deep vein thrombosis (DVT), is a potentially fatal disease with complex pathophysiology. Traditionally, the Virchow triad provided a framework for understanding the pathogenic contributors to thrombus formation, which include endothelial dysfunction, alterations in blood flow and blood hypercoagulability. In the last years, it has become apparent that immunity plays a central role in thrombosis, interacting with classical prothrombotic mechanisms, oxidative stress and vascular factors.

The Vulnerable Elders Survey-13 scale is superior to the simplified Pulmonary Embolism Score Index in predicting 3-month postdischarge mortality in elderly survivors of acute pulmonary embolism.

Introduction: Acute pulmonary embolism (APE) is the most serious manifestation of venous thromboembolism. The simplified Pulmonary Embolism Severity Index (sPESI) is employed for prediction of 30-day mortality in APE. The Vulnerable Elders Survey (VES-13) is used to identify participants at a risk of health impairment.

Th17/Treg imbalance in patients with primary hyperaldosteronism and resistant hypertension.

Introduction: Inflammation plays a pivotal role in blood pressure regulation. Data on experimental models of hypertension and hypertensive patients reflect the imbalance between T regulatory (Treg) and Th17 effector cells (Th17).

Objectives: The aim of this study was to quantify peripheral blood Treg lymphocytes and Th17 subsets in individuals with primary hyperaldosteronism (PHA) and resistant hypertension (RHT) presenting with elevated blood pressure levels and augmented cardiovascular risk when compared with normotensive controls (CTRL).

Acidic urine as a novel risk factor for diuretic resistance and worse in‑hospital prognosis in patients with acute heart failure.

Introduction: Loop diuretic resistance (LDR) is a risk factor for poor prognosis in patients with acute heart failure (AHF). Acidic urine (pH <⁠6) might be associated with diminished effect of diuretics and worse in-hospital course in this patient population. Objectives: The aim of the study was to assess the influence of acidic urine on in-hospital prognosis and diuretic efficacy in patients with AHF.

A look into the use of Raman spectroscopy for brain and breast cancer diagnostics: linear and non-linear optics in cancer research as a gateway to tumor cell identity.

: Currently, intensely developing of linear and non-linear optical methods for cancer detection provides a valuable tool to improve sensitivity and specificity. One of the main reasons for insufficient progress in cancer diagnostics is related to the fact that most cancer types are not only heterogeneous in their genetic composition but also reside in varying microenvironments and interact with different cell types. Until now, no technology has been fully proven for effective detecting of invasive cancer, which infiltrating the extracellular matrix.

Aberrant Protein Phosphorylation in Cancer by Using Raman Biomarkers.

(1) Background: Novel methods are required for analysing post-translational modifications of protein phosphorylation by visualizing biochemical landscapes of proteins in human normal and cancerous tissues and cells. (2) Methods: A label-free Raman method is presented for detecting spectral changes that arise in proteins due to phosphorylation in the tissue of human breasts, small intestines, and brain tumours, as well as in the normal human astrocytes and primary glioblastoma U-87 MG cell lines. Raman spectroscopy and Raman imaging are effective tools for monitoring and analysing the vibrations of functional groups involved in aberrant phosphorylation in cancer without any phosphorecognition of tag molecules.

Advances in Raman imaging combined with AFM and fluorescence microscopy are beneficial for oncology and cancer research.

The aim of this paper is to provide images of the universal cancer Raman biomarkers based on lipidomic, proteomic, glycomic profiles and nanomechanical properties. Biochemical mapping and nanomechanical properties (topography, stiffness and adhesion) of human breast and brain for normal and cancer tissues and cell culture line U87 MG of glioblastoma were obtained using Raman imaging combined with atomic force microscopy (AFM) and fluorescence microscopy. Detailed analysis of breast ductal carcinoma , and astrocytoma brain tissues as well as cells of glioblastoma U87 MG showed that Raman scattering generates images as accurately as histology hematoxylin and eosin stain used in clinical practice with additional advantage of biochemical information.

Monitoring glycosylation metabolism in brain and breast cancer by Raman imaging.

We have shown that Raman microspectroscopy is a powerful method for visualization of glycocalyx offering cellular interrogation without staining, unprecedented spatial and spectral resolution, and biochemical information. We showed for the first time that Raman imaging can be used to distinguish successfully between glycosylated and nonglycosylated proteins in normal and cancer tissue. Thousands of protein, lipid and glycan species exist in cells and tissues and their metabolism is monitored via numerous pathways, networks and methods.

Raman spectroscopy for medulloblastoma.

Purpose: The aim of the study is to use Raman spectroscopy to analyze the biochemical composition of medulloblastoma and normal tissues from the safety margin of the CNS and to find specific Raman biomarkers capable of differentiating between tumorous and normal tissues.

Methods: The tissue samples consisted of medulloblastoma (grade IV) (n = 11). The tissues from the negative margins were used as normal controls.

The biochemical, nanomechanical and chemometric signatures of brain cancer.

Raman spectroscopy and imaging combined with AFM topography and mechanical indentation by AFM have been shown to be an effective tool for analysis and discrimination of human brain tumors from normal structures. Raman methods have potential to be applied in clinical practice as they allow for identification of tumor margins during surgery. In this study, we investigate medulloblastoma (grade IV WHO) (n=5) and the tissue from the negative margins used as normal controls.

Paediatric skin disorders encountered in an emergency hospital facility: a prospective study.

To determine the frequency of skin disorders encountered in a paediatric emergency care unit and to evaluate the benefits of advice from a dermatologist, we prospectively recorded data of children admitted with skin disorders to the emergency care unit during a 5-month period. Diagnostic agreement between paediatricians and dermatologists evaluating the patients separately was assessed. Three hundred and ninety-five children (median age 3 years; interquartile 1-6) were included.

Juvenile xanthogranuloma: a congenital giant form leading to a wide atrophic sequela.

Juvenile xanthogranuloma is the most common non-Langerhans cell histiocytosis of infancy and childhood. It is a benign disorder that usually regresses spontaneously, more often without or with limited skin changes. The clinical features are very pleomorphic and recognition of the atypical presentations should facilitate the diagnosis.

Congenital elephantiasis-like lymphangiomatosis of a lower limb.

The case of a newborn girl with a rare, giant, congenital, tissue lymphangioma giving rise to elephantiasis of the right lower limb is presented. The different imaging methods, especially magnetic resonance imaging, showed no extension of the lesions into the deep structures. At the age of 2 years, the child underwent a roentgenographic skeletal survey, which revealed osteolytic lesions in the femurs and the right tibia.
