Preoperative D‑dimer level and prognosis in patients diagnosed with gastric cancer and undergoing gastric cancer radical surgery: A retrospective cohort study.

Gastric cancer, one of the most aggressive tumors affecting the digestive tract, has seen a rise in both incidence and mortality rates in recent years, with a lack of clear prognostic indicators. D-dimer, a byproduct of fibrin degradation, is a conventional coagulation biomarker that has been investigated as a potential adverse prognostic factor for postoperative cancer patients. However, conflicting results exist, with some studies suggesting that D-dimer is an independent risk factor for the postoperative prognosis of gastric cancer, and others suggesting that there is no significant association between D-dimer level and gastric cancer prognosis.

Adverse Event Assessment of Upadacitinib: A Pharmacovigilance Study Based on the FAERS Database.

Purpose: Upadacitinib, a Janus kinase (JAK) inhibitor, has been approved by the FDA to treat various autoimmune conditions. This study assessed its adverse events by analyzing reports from the FDA Adverse Event Reporting System (FAERS).

Methods: FAERS data from Q3 2019 to Q4 2023 were extracted, and disproportionality analyses were conducted using four statistical measures, reporting odds ratio, proportionate reporting ratio, Bayesian confidence propagation neural network, and empirical Bayesian geometric mean.

Long-term survivals of immune checkpoint inhibitors as neoadjuvant and adjuvant therapy in dMMR/MSI-H colorectal and gastric cancers.

Background: The long-term survival benefit of immune checkpoint inhibitors (ICIs) in neoadjuvant and adjuvant settings is unclear for colorectal cancers (CRC) and gastric cancers (GC) with deficiency of mismatch repair (dMMR) or microsatellite instability-high (MSI-H).

Methods: This retrospective study enrolled patients with dMMR/MSI-H CRC and GC who received at least one dose of neoadjuvant ICIs (neoadjuvant cohort, NAC) or adjuvant ICIs (adjuvant cohort, AC) at 17 centers in China. Patients with stage IV disease were also eligible if all tumor lesions were radically resectable.

Combined use of Donepezil and Memantine increases the probability of five-year survival of Alzheimer's disease patients.

Background: Alzheimer's disease (AD) is the most common neurodegenerative disease. Studying the effects of drug treatments on multiple health outcomes related to AD could be beneficial in demonstrating which drugs reduce the disease burden and increase survival.

Methods: We conducted a comprehensive causal inference study implementing doubly robust estimators and using one of the largest high-quality medical databases, the Oracle Electronic Health Records (EHR) Real-World Data.

Research progress in the development of 3D skin models and their application to in vitro skin irritation testing.

Toxicological assessment of chemicals is crucial for safeguarding human health and the environment. However, traditional animal experiments are associated with ethical, technical, and predictive limitations in assessing the toxicity of chemicals to the skin. With the recent development of bioengineering and tissue engineering, three-dimensional (3D) skin models have been commonly used as an alternative for toxicological studies.

Preparation of a (Ca,Sr,Ba)ZrO Crucible by Slip Casting for the Vacuum Induction Melting of NiTi Alloy.

Vacuum induction melting is a more energy-efficient process for the preparation of a titanium alloy with good homogeneity and low cost. But the crucial problem for this technology is in developing a crucible refractory with high stability. In the present work, a novel (Ca,Sr,Ba)ZrO crucible was prepared by slip casting and its performance in melting NiTi alloy was studied.

A gastric neuroendocrine carcinoma with good prognosis after chemotherapy combined with immunotherapy: A case report (CARE-compliant).

Introduction: Gastric neuroendocrine carcinoma (GNENs), as a highly malignant gastrointestinal tumor, is characterized by easy postoperative metastasis, and its prognosis has always been poor compared to other gastrointestinal tumors. Due to its rarity, there have been few case reports and studies on it. As of now, there is no clear diagnosis and treatment sequence and guidelines.

A causal inference study: The impact of the combined administration of Donepezil and Memantine on decreasing hospital and emergency department visits of Alzheimer's disease patients.

Alzheimer's disease is the most common type of dementia that currently affects over 6.5 million people in the U.S.

Geospatial Analysis of Opioid Dispensing Patterns in California: A 2021 Real-World Study.

The misuse and abuse of opioids has become a serious public health threat in the United States. The state of California has been hit particularly hard by the opioid epidemic, with a noticeable increase in opioid-related fatalities and hospitalizations. This brief report paper aims to contribute to the growing literature by conducting a geospatial analysis of opioid dispensing patterns in California in 2021.

PD-1/PD-L1 Inhibitor Plus Chemotherapy Versus PD-1/PD-L1 Inhibitor in Microsatellite Instability Gastrointestinal Cancers: A Multicenter Retrospective Study.

Purpose: To investigate the efficacy of PD-1/PD-L1 inhibitors plus chemotherapy versus anti-PD-1/PD-L1 monotherapy in advanced microsatellite instability (MSI)/mismatch repair-deficient (dMMR) gastrointestinal cancers.

Methods: We retrospectively recruited patients with MSI/dMMR gastrointestinal cancer who received anti-PD-1/PD-L1 with or without chemotherapy and compared objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) of PD-1/PD-L1 inhibitor plus chemotherapy (chemo-anti-PD-1/PD-L1 group) and PD-1/PD-L1 inhibitor alone (anti-PD-1/PD-L1 group). Propensity score-based overlap weighting analysis was conducted to adjust the baseline covariable imbalance.

Rational design of HJH antimicrobial peptides to improve antimicrobial activity.

Antimicrobial peptides (AMPs) have attracted considerable interest in the past decade due to their advantages for tackling antibiotic resistance. They exhibit potential antimicrobial activity through unique cell membrane destruction mechanism based on their net charge, hydrophobic properties, and α-helix. In this work, a series of HJH peptides was rationally designed and synthesized.

Heavy Mn-doped CsPbBrnanocrystals synthesized by high energy ball milling with high stability.

CsPbX(X = Cl, Br, I) semiconductor nanocrystals (NCs) have excellent optical and photoelectric properties, and are potential core materials for various photoelectric devices. However, the toxicity of Pb and instability have been the key limitations to application of NCs. Herein, using MnBrand MnBr·4HO as manganese sources, heavy Mn-doped CsPbBr(Mn:CsPbBr) NCs are synthesized by high-energy ball grinding, which avoids high temperature, a large number of polar solvents and atmosphere protection required in traditional liquid phase methods.

Sortase A-mediated cyclization of novel polycyclic RGD peptides for αβ integrin targeting.

Cyclic arginine-glycine-aspartic (RGD) peptides that specifically bind to integrin αβ have been developed for drug delivery, tracers, and imaging for tumor diagnosis and treatment. Herein, a series of polycyclic RGD peptides containing dual, tri, and tetra rings were designed and synthesized through sortase A-mediated ligation. An in vitro test on cell adhesion inhibition indicated that the RGD peptide containing tricylic structure exhibited outstanding potency and selectivity for αβ integrin.

Factors associated with the willingness of older people to engage with long-term care services: A systematic review.

The ageing of the population has resulted in an increase in the demand for long-term care services for older people, but with limited resources, its challenges have also been highlighted. Although factors affecting the willingness of older people to engage with long-term care services have been widely reported, however, systematic review has not synthesised the evidence, and its associated factors remain unclear. This systematic review aims to study and synthesise the best available evidence on the potential factors related to the willingness of older people to engage with long-term care services.

Understanding charge storage in NbCT MXene as an anode material for lithium ion batteries.

MXenes represent an emerging family of two-dimensional materials of transition metal carbides/carbonitrides terminated with functional groups like -O, -OH, and -F on the chemically active surface of MX slabs. As a member of the family, NbCT exhibits superior lithium storage capacity over most of the other MXenes as anode materials in lithium-ion batteries (LIBs). However, an in-depth understanding of the charge storage mechanism is still lacking so far.
