The case concerns a 20-year-old patient with Canadian Cardiovascular Society class II angina who was initially referred for aortic valve replacement because of a suspected high-grade aortic valve stenosis with increased transvalvular gradients (max/mean: 70/40 mm Hg) measured by Doppler echocardiography. Examinations using transesophageal echocardiography and computed tomography showed a sufficiently opening bicuspid aortic valve, excluded supra- and subvalvular stenoses, and measured a narrow aorta (diameter: 2 cm). The explanation for the highly increased gradients across the aortic valve was the pressure recovery (PR) phenomenon, which cannot be detected by Doppler gradients.

Background: Psoriasis is a chronic inflammatory condition that increases the risk of vascular issues, ranging from mild artery damage to severe events such as heart attacks and strokes. This systematic review and meta-analysis aimed to evaluate the relationship between psoriasis and carotid intima-media thickness (CIMT), a marker of subclinical atherosclerosis.

Methods: A comprehensive search of Embase, PubMed/Medline, Scopus, and CINAHL via EBSCO was conducted up until June 2023 using the terms "Atherosclerosis AND Psoriasis.

Background: Impaired renal function can increase cardiac troponin levels due to reduced elimination, potentially affecting its diagnostic utility. Limited data exist on high-sensitivity cardiac troponin I (hs-cTnI) kinetics after cardiac surgery relative to renal function. This study evaluates how impaired renal function influences hs-cTnI kinetics following cardiac surgery, distinguishing between patients with and without postoperative myocardial infarction (PMI).

Background: The tricuspid annular plane systolic excursion (TAPSE) assessed by echocardiography has failed in predicting outcomes in patients with severe tricuspid regurgitation (TR) undergoing transcatheter tricuspid valve intervention (TTVI). Considering the complex shape of the tricuspid annulus and right ventricle, as well as the difficult echocardiographic image acquisition of the right heart, cardiac computed tomography (CT) might be superior for the analysis of the annular excursion. Thus, this study aimed to analyze whether CT-captured TAPSE provides additional value in predicting outcomes after TTVI.

Background: Patients with severe tricuspid regurgitation (TR) typically present with heterogeneity in the extent of cardiac dysfunction and extra-cardiac comorbidities, which play a decisive role for survival after transcatheter tricuspid valve intervention (TTVI).

Objectives: This aim of this study was to create a survival tree-based model to determine the cardiac and extra-cardiac features associated with 2-year survival after TTVI.

Methods: The study included 918 patients (derivation set, n = 631; validation set, n = 287) undergoing TTVI for severe TR.

Multiciliated cells (MCCs) ensure fluid circulation in various organs. Their differentiation is marked by the amplification of cilia-nucleating centrioles, driven by a genuine cell-cycle variant, which is characterized by wave-like expression of canonical and non-canonical cyclins such as Cyclin O (CCNO). Patients with CCNO mutations exhibit a subtype of primary ciliary dyskinesia called reduced generation of motile cilia (RGMC).

Background: Primary ciliary dyskinesia is a rare genetic disorder caused by insufficient mucociliary clearance leading to chronic airway infections. The diagnostic guideline of the European Respiratory Society primarily recommends an evaluation of the clinical history ( by the PICADAR prediction tool), nasal nitric oxide production rate measurements, high-speed videomicroscopy analysis of ciliary beating and an assessment of ciliary axonemes transmission electron microscopy. Genetic testing can be implemented as a last step.

Article Synopsis
  • * Data were collected from 408 PCD patients across 12 countries, focusing on their lung function and the presence of common respiratory pathogens, with a significant finding that those with certain pathogens had lower lung function scores.
  • * The results indicated that certain pathogens were strongly associated with decreased lung function, particularly in adults, highlighting the need for early eradication strategies and timely treatment of infections in PCD patients.

Objective:  This study aimed to evaluate the potential risk factors of lifetime urolithiasis occurrence on a nationwide scale in Iran.

Methods:  All data regarding urinary stone events were extracted from the cross-sectional Iran National Stone Survey (INSS) study, and the possible determinants of urolithiasis incidence were evaluated.

Results:  Our multivariable logistic regression suggested that while older age at presentation, male sex, and a positive family history of urolithiasis in either of the patient's parents or siblings were all significantly associated with an increased odds of lifetime urolithiasis occurrence (all P < .

Background: Nephronophthisis (NPH) comprises a heterogeneous group of inherited renal ciliopathies clinically characterized by progressive kidney failure. So far, definite diagnosis is based on molecular testing only. Here, we studied the feasibility of NPHP1 and NPHP4 immunostaining of nasal epithelial cells to secure and accelerate the diagnosis of NPH.

Disease-causing bi-allelic DNA variants in and are frequent causes of the hereditary disorder of primary ciliary dyskinesia (PCD). The encoded proteins form a molecular ruler complex, crucial for maintaining the 96 nm repeat units along the ciliary axonemes. Defects of those proteins cause a stiff, rapid, and flickery ciliary beating pattern, recurrent respiratory infections, axonemal disorganization, and abnormal assembly of GAS8, CCDC39, and DNALI1.

Background: Primary ciliary dyskinesia is a genetic disorder caused by aberrant motile cilia function that results in defective ciliary airway clearance and subsequently leads to recurrent airway infections and bronchiectasis. We aimed to determine: how many functional multiciliated airway cells are sufficient to maintain ciliary airway clearance?

Methods: To answer this question we exploited the molecular defects of the X-linked recessive primary ciliary dyskinesia variant caused by pathogenic variants in (), characterised by immotile cilia in affected males. We carefully analysed the clinical phenotype and molecular defect (using immunofluorescence and transmission electron microscopy) and performed studies (particle tracking in air-liquid interface cultures) and studies (radiolabelled tracer studies) to assess ciliary clearance of respiratory cells from female individuals with heterozygous and male individuals with hemizygous pathogenic variants.

Article Synopsis
  • Primary ciliary dyskinesia (PCD) is a rare genetic disorder that affects ciliary function, leading to airway clearance issues and sometimes organ positioning defects (laterality defects), with a study conducted across 19 countries to analyze gene defects and their clinical implications.
  • The study involved 1236 individuals with a variety of pathogenic DNA variants and found significant geographical differences in PCD genotypes, with varying rates of laterality defects and distinct genetic characteristics linked to different countries.
  • Results revealed that individuals with PCD often have lower lung function (measured by forced expiratory volume) and that the presence of certain genetic variants can correlate with more severe clinical outcomes, highlighting the importance of genetic understanding in diagnosing

Background: Baseline right ventricular (RV) function derived from 3-dimensional analyses has been demonstrated to be predictive in patients undergoing transcatheter tricuspid valve repair (TTVR). The complex nature of these cumbersome analyses makes patient selection based on established imaging methods challenging. Artificial intelligence (AI)-driven computed tomography (CT) segmentation of the RV might serve as a fast and predictive tool for evaluating patients prior to TTVR.
