What can we learn from pathophysiology and therapeutic targetable pathways from all genetic causes and associations in PH?

Pulmonary hypertension (PH) encompasses a group of conditions which ultimately lead to elevated pulmonary arterial pressure. PH is classified into five subgroups, of which Group 1 pulmonary arterial hypertension (PAH), is the most extensively studied. Numerous causal genes have been identified in PAH, most notably germline mutations in bone morphogenetic protein receptor type 2 () and the wider BMP pathway.

Clinical phenotyping uncovers heterogeneous associations between corticosteroid treatment and survival in critically ill COVID-19 patients.

Purpose: Disease heterogeneity in coronavirus disease 2019 (COVID-19) may render the current one-size-fits-all treatment approach suboptimal. We aimed to identify and immunologically characterize clinical phenotypes among critically ill COVID-19 patients, and to assess heterogeneity of corticosteroid treatment effect.

Methods: We applied consensus k-means clustering on 21 clinical parameters obtained within 24 h after admission to the intensive care unit (ICU) from 13,279 COVID-19 patients admitted to 82 Dutch ICUs from February 2020 to February 2022.

Emotional Distress, Anxiety, and General Health Status in Patients With Newly Identified Small Pulmonary Nodules: Results From the Watch the Spot Trial.

Background: Anxiety and emotional distress have not been studied in large, diverse samples of patients with pulmonary nodules.

Research Question: How common are anxiety and distress in patients with newly identified pulmonary nodules, and what factors are associated with these outcomes?

Study Design And Methods: This study surveyed participants in the Watch the Spot Trial, a large, pragmatic clinical trial of more vs less intensive strategies for radiographic surveillance of patients with small pulmonary nodules. The survey included validated instruments to measure patient-centered outcomes such as nodule-related emotional distress (Impact of Event Scale-Revised) and anxiety (Six-Item State Anxiety Inventory) 6 to 8 weeks following nodule identification.

Pediatric acute flaccid myelitis: Evaluation of diagnostic criteria and differentiation from other causes of acute flaccid paralysis.

Background: Acute flaccid paralysis (AFP) is characterized by rapidly progressive limb weakness with low muscle tone. It has a broad differential diagnosis, which includes acute flaccid myelitis (AFM), a rare polio-like condition that mainly affects young children. Differentiation between AFM and other causes of AFP may be difficult, particularly at onset of disease.
