Exploring the Spectrum of Comorbidities Associated with Primary Aldosteronism: Insights from a Large Real-World Case-Control Study.

: Primary aldosteronism (PA) is a common cause of endocrine hypertension, characterized by excessive aldosterone secretion leading to hypertension, hypokalemia, and metabolic alkalosis. While historically diagnosed based on this classic triad of symptoms, current understanding reveals a more nuanced presentation. This study aimed to investigate the prevalence of PA-associated diseases in a large German population.

Impact of Cortisol-Cosecretion on Adrenal Venous Sampling Results in Primary Aldosteronism: Study of 225 Cases.

: Mild autonomous cortisol secretion (MACS) can coexist with primary aldosteronism (PA). The purpose of our study was to evaluate whether (MACS) influences parameters analyzed during adrenal venous sampling (AVS) in patients with PA. : Patients with PA from the SPAIN-ALDO Registry and the German Conn's Registry with available 1 mg-dexamethasone suppression test (DST) and AVS were included.

Larger size of Conn's adenoma is associated with lower cure rates post adrenalectomy.

Background: The cure for patients with primary hyperaldosteronism (PHA) secondary to solitary adrenal adenoma is adrenalectomy. We investigated the impact of size of Conns' tumour on hypertension resolution in a multi-ethnic South East Asian Cohort.

Methods: Retrospective cohort study of patients who underwent surgery for PHA between January 2010 to December 2022 was performed.

Aspergillus-mediated allergic airway inflammation is triggered by dendritic cell recognition of a defined spore morphotype.

Background: Exposure to fungi, especially Aspergillus fumigatus, can elicit potent allergic inflammation that triggers and worsens asthmatic disease. Dendritic cells (DCs) initiate allergic inflammatory responses to allergic stimuli. However, it is unclear if Af spores during isotropic growth (early spore swelling) can activate DCs to initiate allergic responses or if germination is required.

Leptin augments IL-13-induced airway eotaxins and submucosal eosinophilia in obesity-associated asthma.

Background: Airway tissue eosinophilia can be an observed feature of obesity-associated type 2 (T2) asthma, but the processes mediating this inflammation are unknown.

Objective: To investigate a process whereby leptin, an adipokine elevated in obesity, potentiates pulmonary eosinophilia and eotaxin production by airway fibroblasts in T2 asthma.

Methods: We assessed associations between body mass index and airway eosinophilia as well as leptin and eotaxin production in 78 participants with asthma, 36 of whom exhibited obesity.

DISTANT RIBOSE 2'-O-METHYLATION OF 23S rRNA HELIX 69 PRE-ORDERS THE CAPREOMYCIN DRUG BINDING POCKET AT THE RIBOSOME SUBUNIT INTERFACE.

Loss of ribosomal RNA (rRNA) modifications incorporated by the intrinsic methyltransferase TlyA results in reduced sensitivity to tuberactinomycin antibiotics such as capreomycin. However, the mechanism by which rRNA methylation alters drug binding, particularly at the distant but functionally more important site in 23S rRNA Helix 69 (H69), is currently unknown. We determined high-resolution cryo-electron microscopy structures of the 70S ribosome with or without the two ribose 2'-O-methyl modifications incorporated by TlyA.

Plasma Glial Fibrillary Acid Protein and Phosphorated Tau 181 Association with Presynaptic Density-Dependent Tau Pathology at F-SynVesT-1 Brain PET Imaging.
