Background/aim: To investigate the efficacy (prognosis, coagulation/inflammation biomarkers) and safety (bleeding events) of different anticoagulation dosages in COVID-19 inpatients.
Patients And Methods: COVID-19 inpatients (Athens, Greece) were included. The "Enhanced dose THRomboprophylaxis in Admissions (ETHRA)" protocol was applied in certain Departments, suggesting the use of intermediate anticoagulation dosage. The primary endpoint was a composite of intubation/venous thromboembolism/death. Inflammation/coagulation parameters were assessed.
Results: Among 127 admissions, 95 fulfilled the inclusion criteria. Twenty-one events (4 deaths, 17 intubations) were observed. Regression analysis demonstrated significant reduction of events with intermediate or therapeutic dosage [HR=0.16 (95%CI=0.05-0.52) p=0.002; HR=0.17 (0.04-0.71) p=0.015, respectively]. D-Dimer values were higher in those who met the composite endpoint. Intermediate dosage treatment was associated with decreased values of ferritin. Three patients (3%) had minor hemorrhagic complications.
Conclusion: Anticoagulation treatment (particularly intermediate dosage) appears to have positive impact on COVID-19 inpatients' prognosis by inhibiting both coagulation and inflammatory cascades.

Purpose: Nivolumab plus ipilimumab (NIVO + IPI) is a first-in-class combination immunotherapy for the treatment of intermediate- or poor (I/P)-risk advanced or metastatic renal cell carcinoma (mRCC). Currently, there are limited real-world data regarding clinical effectiveness beyond 12-24 months from treatment initiation. In this real-world study, treatment patterns and clinical outcomes were evaluated for NIVO + IPI in a community oncology setting.

Background: Aripiprazole and risperidone, widely used atypical antipsychotics, are commonly adjunctively prescribed in clinical practice. When aripiprazole was combined with risperidone, the genotype of drug-metabolizing enzymes and liver impairment may lead to complex pharmacokinetic changes. The Physiologically Based Pharmacokinetic (PBPK) model can predict the influence of these factors on plasma concentration and optimize dosage regimens.

Since ancient times, traditional Chinese medicine pills have occupied a key position among different dosage forms of traditional Chinese medicine. With the aims of comprehensively improving the overall quality and innovating key technologies in the manufacturing of the pills, this article elaborates on the principles and new technology applications in pulverizing, sterilization, agglomeration, forming, and drying. In addition, modern technologies such as biosensing, image analysis, texture property evaluation, and moisture analysis can comprehensively and accurately characterize the quality of key materials in the manufacturing of traditional Chinese medicine pills, thereby achieving strict control over the quality of raw materials, intermediates, and final products and further monitoring and optimizing the entire production process of pill preparations.

In recent years, the influence of dietary-related factors on neurodegenerative diseases has received considerable attention in the academic community, notably involving the food additive sodium nitrite (NaNO) and intermittent fasting behavior. However, the effects of NaNO and intermittent fasting on spatial learning and memory have not been thoroughly investigated. This study conducted a controlled experiment to explore the impact of NaNO and intermittent fasting on the hyperphosphorylation of hippocampal neurofilament (NF) and tau proteins, as well as spatial learning and memory in rats.

Background: MECP2 Duplication Syndrome, also known as X-linked intellectual developmental disorder Lubs type (MRXSL; MIM: 300260), is a neurodevelopmental disorder caused by copy number gains spanning MECP2. Despite varying genomic rearrangement structures, including duplications and triplications, and a wide range of duplication sizes, no clear correlation exists between DNA rearrangement and clinical features. We had previously demonstrated that up to 38% of MRXSL families are characterized by complex genomic rearrangements (CGRs) of intermediate complexity (2 ≤ copy number variant breakpoints < 5), yet the impact of these genomic structures on regulation of gene expression and phenotypic manifestations have not been investigated.
