Article Synopsis
  • Patients with spontaneous intracranial hypotension (SIH) often experience cognitive issues such as difficulties in concentration and memory, prompting the inclusion of cognitive tests in their evaluation.
  • A study involving 18 patients with active spinal CSF leaks showed that many experienced mild cognitive impairment upon admission, but their cognitive scores significantly improved after surgical treatment of the leaks.
  • The results support a possible link between cognitive dysfunction and spinal CSF loss, indicating that addressing spinal CSF leaks may help alleviate cognitive issues in these patients.

Cobalamin (Cbl) is an essential cofactor for methionine synthase (MS) and methylmalonyl-CoA mutase (MUT), but it must first undergo chemical processing for utilization in animals. In humans, this processing comprises β-axial ligand cleavage and Cbl reduction and is performed by the enzyme MMACHC (HsCblC). Although the functionality of CblC is well-understood in higher order organisms, little is known about the evolutionary origin of these enzymes and the reactivity of CblCs in lower-order organisms with unique environmental and cellular conditions.

The structural and functional integrity of conduits used for coronary artery bypass grafting is critical for graft patency. Disruption of endothelial integrity and endothelial dysfunction are incurred during conduit harvesting subsequent to mechanical or thermal injury and during conduit storage prior to grafting, leading to acute thrombosis and early graft failure. Late graft failure, in particular that of vein grafts, is precipitated by progressive atherogenesis.

Leniolisib, an oral, targeted phosphoinositide 3-kinase delta (PI3Kδ) inhibitor, was well-tolerated and efficacious versus placebo in treating individuals with activated PI3Kδ syndrome (APDS), an ultra-rare inborn error of immunity (IEI), in a 12-week randomised controlled trial. However, longer-term comparative data versus standard of care are lacking. This externally controlled study compared the long-term effects of leniolisib on annual rate of respiratory tract infections and change in serum immunoglobulin M (IgM) levels versus current standard of care, using data from the leniolisib single-arm open-label extension study 2201E1 (NCT02859727) and the European Society for Immunodeficiencies (ESID) registry.

Clinical updates of B‑cell maturation antigen‑targeted therapy in multiple myeloma (MM) and relapsed/refractory MM (Review).

Int J Mol Med

February 2025

Department of Gastrointestinal Surgery, Affiliated Nanhua Hospital, University of South China, Hengyang, Hunan 421002, P.R. China.

Despite significant progress in managing multiple myeloma (MM) in recent years, certain patients still have a short duration of therapeutic response, often relapsing within 18 months. These patients typically have high‑risk genetic mutations and may show little to no response to current treatments, highlighting the need for further exploration of optimal therapeutic targets for MM. B‑cell maturation antigen (BCMA), highly expressed in mature B lymphocytes and plasma cells and upregulated in MM, is a promising therapeutic target.

Background And Purpose: Neoadjuvant chemoradiotherapy (NCRT) is a standard treatment option for locally advanced rectal cancer. However, there is still conflicting data about the genetic landscape and potential dynamics during and after NCRT. This study evaluated oncogenic driver mutations before NCRT and investigated corresponding resection samples after treatment.

Objectives: This study aimed to examine the effect of electrode array design, insertion angle, scalar position, and insertion technique on the occurrence of postoperative subjective vertigo following cochlear implant (CI) surgery using questionnaires in conjunction with objective vestibular functional measurements.

Materials And Methods: We prospectively evaluated subjective vertigo using the Dizziness Handicap Inventory (DHI). Additionally, we performed videonystagmography, video head-impulse tests, and vestibular-evoked myogenic potentials to assess the objective vestibular function preoperatively, at four weeks and 12 months after CI.

Rationale And Objectives: The purpose of this study was to explore intra-individual differences in pericoronary adipose tissue (PCAT) fat attenuation index (FAI) between photon-counting detector (PCD)- and energy-integrating detector (EID)-CT.

Material And Methods: Patients were prospectively enrolled for a PCD-CT research scan within 30 days of EID-CT. Both acquisitions were reconstructed using a Qr36 kernel at 0.

Electronic address:

Mammalian pluripotent cells first segregate into neuroectoderm (NE), or mesoderm and endoderm (ME), characterized by lineage-specific transcriptional programs and chromatin states. To date, the relationship between transcription factor activities and dynamic chromatin changes that guide cell specification remains ill-defined. In this study, we employ mouse embryonic stem cell differentiation toward ME lineages to reveal crucial roles of the Tbx factor Eomes to globally establish ME enhancer accessibility as the prerequisite for ME lineage competence and ME-specific gene expression.

Objectives: Diffuse alveolar hemorrhage (DAH) is a life-threatening complication of systemic lupus erythematosus and small vessel vasculitis. We previously showed that neutrophil extracellular traps (NETs) were associated with the pathogenesis of pristane-induced DAH and demonstrated that neutrophil NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome assembly participated in NET generation under sterile stimulation. We investigated whether NLRP3 inflammasome assembly in neutrophils may drive pulmonary NETosis in a mouse model of pristane-induced DAH.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer-related deaths worldwide. Although the risk of developing CRC increases with age, approximately 10% of newly diagnosed cases occur in individuals under the age of 50. Significant changes in dietary habits in young adults since industrialization create a favorable microenvironment for colorectal carcinogenesis.

Institute and Outpatient Clinic for Occupational, Social and Environmental Medicine, University Hospital, LMU Munich, Comprehensive Pneumology Center Munich (CPC-M), Member of the German Center for Lung Research (DZL), Munich, Bavaria, Germany.

Background: In patients with chronic diseases, including those with chronic obstructive pulmonary disease (COPD), knowledge on the disease and its self-management is considered as relevant for improving disease control and long-term outcome. We studied to which extent components of knowledge depended on potential predictors, such as participation in educational programs and disease severity. For example, the perception of exacerbations or GOLD grade might modulate the content and reliability of COPD understanding.

Introduction: Osteoporotic vertebral fractures are a major cause of morbidity, disability, and mortality among the elderly. Traditional methods for fracture risk assessment, such as dual-energy X-ray absorptiometry (DXA), may not fully capture the complex factors contributing to fracture risk. This study aims to enhance vertebral fracture risk prediction by integrating radiomics features extracted from computed tomography (CT) scans with clinical data, utilizing advanced machine learning techniques.

Vocal Tract Configurations of Professional Operatic Singers During Sustained Phonation.

J Voice

December 2024

Freiburg Institute for Musicians' Medicine, Medical Center, University of Freiburg, Elsässer Str 2m, 79106, Freiburg, Germany; Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Objectives: In voice production, interactions occur between the oscillating vocal folds, the respiratory system, and the vocal tract. However, it is not yet sufficiently understood how the respiratory system could affect the vocal tract configuration. It is hypothesized that a reduction in tracheal pull, caused by decreasing lung volume, along with shifts in dominant exhalation forces (from inspiratory to expiratory muscles), leads to a larynx elevation with shortening of the vocal tract tube, and consecutively, articulatory adjustments to preserve consistent sound quality.
