Intracellular concentration of ADA2 is a marker for monocyte differentiation and activation.

Adenosine, a critical molecule regulating cellular function both inside and outside cells, is controlled by two human adenosine deaminases: ADA1 and ADA2. While ADA1 primarily resides in the cytoplasm, ADA2 can be transported to lysosomes within cells or secreted outside the cell. Patients with ADA2 deficiency (DADA2) often suffer from systemic vasculitis due to elevated levels of TNF-α in their blood.

Hepatopulmonary syndrome from liver disease associated with autosomal recessive polycystic kidney disease.

Hepatopulmonary syndrome (HPS) is a life-threatening complication of chronic liver disease (CLD) that currently can be managed only by liver transplant. Though uncommon, some children with kidney disease have coexistent CLD and hence are at risk of developing HPS. Paediatric cases of HPS are rarely described in the nephrology literature.

Comparative approach for abdominal wall reconstruction after ventral hernia: open versus minimally invasive surgery.

Introduction: The classic open ventral hernia repair provides excellent results in recurrences. However, wound complications are the Achilles heel for a good overall clinical outcome. Laparoscopic surgery is in general associated with less pain, better esthetic results, faster recovery, and lower incidence of wound complications.

Volumetry of Selected Brain Regions-Can We Compare MRI Examinations of Different Manufacturers and Field Strengths?

Purpose: Magnetic Resonance Imaging based brain segmentation and volumetry has become an important tool in clinical routine and research. However the impact of the used hardware is only barely investigated. This study aims to assess the influence of scanner manufacturer, field strength and head-coil on volumetry results.

Recent trends and outcomes in immediate and delayed sequential bilateral cataract surgeries: a nationwide cohort study in South Korea.

Purpose: To analyze the latest annual trends in immediate sequential bilateral cataract surgery (ISBCS) and delayed sequential bilateral cataract surgery (DSBCS) among patients with bilateral cataracts in Korea, and to identify the factors influencing the choice of surgery and the outcomes associated with ISBCS and DSBCS.

Methods: This retrospective, nationwide cohort study included all patients aged 65 and older who were covered by the Korean National Health Insurance and underwent ISBCS or DSBCS from 2016 to 2021. The study recorded yearly numbers of ISBCS and DSBCS procedures, the interval between surgeries in DSBCS cases, patient demographics, types of implanted intraocular lenses (IOLs), and the incidence of cystoid macular edema and endophthalmitis following ISBCS or DSBCS.

Activation of the COX-2/mPGES-1/PGE-2 cascade through the NLRP3 inflammasome contributes to Angiostrongylus cantonensis-induced eosinophilic meningoencephalitis.

Prostaglandin E2 (PGE-2) is synthesised by cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synthase 1 (mPGES-1). PGE-2 exhibits pro-inflammatory properties in inflammatory conditions. However, there remains limited understanding of the COX-2/mPGES-1/PGE-2 pathway in Angiostrongylus cantonensis-induced meningoencephalitis.

Performance evaluation of the LIOFeron®TB/LTBI IGRA for screening of paediatric LTBI and tuberculosis.

Purpose: High-accuracy diagnostic screening tests for Mycobacterium tuberculosis (MTB) infection are required, primarily to detect patients with latent infections (LTBIs) in order to avoid their progression to active tuberculosis disease. The performance of the novel IGRA LIOFeron®TB/LTBI was evaluated in children. The originality of this test is the new MTB antigen contained (L-alanine dehydrogenase), identified as a tool to differentiate active TB from LTBI infection.

Impact of calreticulin mutations on treatment and survival outcomes in myelofibrosis during ruxolitinib therapy.

Calreticulin (CALR) mutations are detected in around 20% of patients with primary and post-essential thrombocythemia myelofibrosis (MF). Regardless of driver mutations, patients with splenomegaly and symptoms are generally treated with JAK2-inhibitors, most commonly ruxolitinib. Recently, new therapies specifically targeting the CALR mutant clone have entered clinical investigation.
