Background And Objective: Total glucosides of paeony (TGP) capsules, tripterygium glycoside tablets (TGT), and celecoxib are commonly used drugs in clinical practice for the treatment of Rheumatoid arthritis (RA). An UPLC-MS/MS method for the analysis of celecoxib in beagle dogs was developed, the herb-drug interactions (HDIs) between TGP and TGT with celecoxib were studied based on pharmacokinetics.
Methods: The method of acetonitrile precipitation was applied to process plasma samples.

Securing sustainable access to existing antibiotics optimises agent choice for individual treatments and is crucial to curb antibiotic resistance. Access to antibiotics is often restricted in many countries, due to general market unavailability or episodic shortages. This article outlines key policy options to maintain availability of existing antibiotics and enhance antibiotic supply chain resilience focusing on the perspectives of European Union (EU) and European Economic Area (EEA) institutions and member states.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.

Imaging inflammation holds immense potential for advancing the diagnosis, treatment and prognosis of many conditions. The lack of a specific and sensitive positron emission tomography (PET) probe to detect inflammation is a critical challenge. To bridge this gap, we present CD45-PET imaging, which detects inflammation with exceptional sensitivity and clarity in several preclinical models.

Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses. However, detailed mechanisms of such processes remain unclear.

Purpose: The expression of the respiratory events in OSA is influenced by different mechanisms. In particular, REM sleep can highly increase the occurrence of events in a subset of OSA patients, a condition dubbed REM-OSA (often defined as an AHI 2 times higher in REM than NREM sleep). However, a proper characterization of REM-OSA and its pathological sequelae is still inadequate, partly because of limitations in the current definitions.

We introduce a quantum-classical generative model for small-molecule design, specifically targeting KRAS inhibitors for cancer therapy. We apply the method to design, select and synthesize 15 proposed molecules that could notably engage with KRAS for cancer therapy, with two holding promise for future development as inhibitors. This work showcases the potential of quantum computing to generate experimentally validated hits that compare favorably against classical models.

To better understand drug resistance mechanisms to CDK4/6 inhibitors and inform precision medicine, we analyze real-world multi-omics data from 400 HR+/HER2- metastatic breast cancer patients treated with CDK4/6 inhibitors plus endocrine therapies, including 200 pre-treatment and 227 post-progression samples. The prevalences of ESR1 and RB1 alterations significantly increase in post-progression samples. Integrative clustering analysis identifies three subgroups harboring different resistance mechanisms: ER driven, ER co-driven and ER independent.

Background: Allergic rhinitis (AR) multimorbidity may need to be considered a specific disease because of distinct clinical and immunological differences from AR alone. Allergic multimorbidity often involves polysensitization, where allergen-specific immunoglobulin E (IgE) plays a significant role.
Objective: This study aims to explore differences in allergen IgE sensitization patterns between AR alone and AR multimorbidity.

Objective: We assessed the impact of a food-provisioning intervention on diet quality in children with obesity.
Methods: Participants (n = 33, aged 6-11 years) were randomly assigned to either usual care (intensive health behavior and lifestyle treatment) or intervention (usual care + food provisioning; high-fiber, low-dairy diet) for 4 weeks. The primary outcome was a change in child diet quality at Week 4.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Dimeric IgA (dIgA) is the dominant antibody in many mucosal tissues. It is actively transported onto mucosal surfaces as secretory IgA (sIgA) which plays an integral role in protection against enteric pathogens, particularly in young children. Therapeutic strategies that deliver engineered, potently neutralizing antibodies directly into the infant intestine through breast milk could provide enhanced antimicrobial protection for neonates.

Methods: HRQOL, frailty, and functioning were assessed using validated questionnaires at inclusion, at discharge, and up to six months later (M6) in patients aged over 65 years hospitalised for severe acute respiratory or bloodstream infections, and matched controls hospitalised for non-infectious conditions. Comparative analyses employed multilevel mixed-effect linear or logistic models to assess changes from inclusion.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver condition characterized by excessive hepatic fat accumulation. Early diagnosis is crucial as NAFLD can progress to more severe conditions like steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma without timely intervention. While liver biopsy remains the gold standard for NAFLD assessment, abdominal ultrasound (US) imaging has emerged as a widely adopted non-invasive modality due to convenience and low cost.

Aim: The aim of the study is to determine sac volume based on radiological examinations in patients undergoing surgery for myelomeningocele (MMC) and to investigate the relationship of sac volume with hydrocephalus and Chiari malformation type 2 (CM) with a view to determining the optimum length of follow-up and recommend a treatment plan.
Material And Methods: The present study involved the retrospective review of radiologic examinations and medical files of 81 patients who underwent surgery for myelomeningocele between 2015 and 2022 in the neurosurgery clinic of Ankara Training and Research Hospital. Then, MMC sac volumes were measured and the statistical relationship of these measurements with the Evans Index, progressive enlargement of the ventricles after sac repair and CM was investigated.

Background: Fermentation of dietary fiber by the gut microbiota leads to the production of metabolites called short-chain fatty acids, which lower blood pressure and exert cardioprotective effects. Short-chain fatty acids activate host signaling responses via the functionally redundant receptors GPR41 and GPR43, which are highly expressed by immune cells. Whether and how these receptors protect against hypertension or mediate the cardioprotective effects of dietary fiber remains unknown.

Background: Hypotensive episodes detected by 24-hour ambulatory blood pressure (BP) monitoring capture daily cumulative hypotensive stress and could be clinically relevant to cognitive impairment, but this relationship remains unclear.
Methods: We included participants from the Systolic Blood Pressure Intervention Trial (receiving intensive or standard BP treatment) who had 24-hour ambulatory BP monitoring measured near the 27-month visit and subsequent biannual cognitive assessments. We evaluated the associations of hypotensive episodes (defined as systolic BP drops of ≥20 mm Hg between 2 consecutive measurements that reached <100 mm Hg) and hypotensive duration (cumulative time of systolic BP <100 mm Hg) with subsequent cognitive function using adjusted linear mixed models.
