Summary: Atherosclerosis is a chronic disease with inflammatory components, now recognized as an active autoimmune process involving both innate and adaptive immune pathways. One of the key factors driving this process is the presence of modified LDL, which leads to the formation of oxidation-specific epitopes recognized by immune cells. Macrophage response to these epitopes is crucial for initiating and promoting inflammation in the arteries.

Summary: This case describes an atypical presentation of cutaneous xanthomas caused by lipoprotein X dyslipidemia triggered by cholestatic fulminant hepatitis due to trimethoprim-sulfamethoxazole hypersensitivity. Significant improvement was seen in the patient's symptoms after treatment with cholestyramine and apheresis.

Summary: Atherosclerosis is the pathological basis of acute cardiovascular and cerebrovascular diseases, with oxidized LDL being recognized as a major factor in its development. Numerous studies have shown that oxidized LDL can modulate the phenotypes of macrophages in atherosclerosis. This review summarizes the research progress on how oxidized LDL regulates macrophage polarization, which may provide new targets for the treatment of atherosclerosis.

Summary: The study demonstrated that oxidized low-density lipoprotein (OxLDL) downregulates ABCA1 expression through the MEK/ERK/LXR pathway, leading to lipid accumulation in INS-1 cells, potentially resulting in impaired insulin synthesis and glucose-stimulated insulin secretion (GSIS).

Summary: Our study demonstrates that the receptor Tim4 mediates the interaction between macrophages and microplastics through aromatic-aromatic interactions. It is involved in the engulfment of PS microplastics and MWCNTs, and disrupts the process of efferocytosis. These findings suggest that chronic exposure to large amounts of PS microplastics may lead to chronic inflammation and autoimmune diseases.

Summary: This study investigated lipid profiles in patients with ECCA and found that TC and sdLDL-C levels were significantly elevated while LDL-C levels were slightly lower in the ECCA group. After cholestasis relief, TC and sdLDL-C levels significantly decreased, and patients showed normal lipoprotein patterns.

Summary: PEITC, a naturally occurring isothiocyanate in cruciferous vegetables, has the potential to inhibit foam cell formation and may be a candidate for the treatment and prevention of vascular inflammation and atherosclerosis. It downregulates the expression of key genes related to lipid accumulation and inflammation, while upregulating genes associated with cholesterol efflux.

Summary: This multicenter retrospective observational study aimed to investigate whether early-phase prothrombin time-international normalized ratio (PT-INR) is an interventional prognostic indicator for patients with acute liver injury. The results showed that PT-INR on day 1 is the most accurate independent predictor for prognosis, and patients with PT-INR>=1.3 on day 1 have significantly lower transplant-free survival rates.

Summary: The study found that mature Plasmodium falciparum parasites are rarely found in the peripheral blood because they are sequestered and attached to the endothelium. Intensive sequestration is associated with a delay in parasite clearance after artemisinin-based treatment. Sequestration plays an important role in the efficacy of artemisinin treatment for malaria.

Summary: HDL serves as dynamic transporters of various molecular cargo and plays important roles in lipid metabolism and inflammation. This study overcomes technical barriers and sheds light on the pathways involved in HDL-mediated bidirectional transport of sRNAs between immune cells. By utilizing a lipid-penetrating RNA-specific fluorescence dye, the absolute concentration of HDL-transported sRNAs is quantified, and HDL-mediated intercellular RNA transport between immune cells is characterized.

Summary: Despite global COVID-19 vaccination campaigns, the pandemic remains a significant medical and social problem. The Ortho VITROS SARS-CoV-2 spike-specific quantitative IgG assay has been developed to assess neutralizing antibodies against SARS-CoV-2 spike antibodies. This study evaluated the clinical performance of VITROS S-IgG in Japan and found a good correlation with the surrogate virus neutralizing antibody test. The results suggest that VITROS S-IgG can be a useful diagnostic tool for assessing immune responses to vaccination and herd immunity, but careful analysis is necessary to interpret the results.

Summary: Recent studies have shown that using machine learning to predict treatment response in patients with primary biliary cholangitis (PBC) may predict prognosis. This study used machine learning and pretreatment data to predict treatment response in PBC patients and evaluated it using the Paris II criteria. The results showed that machine learning models could improve treatment response prediction and enhance prognosis.

Summary: This study investigated the impact of the COVID-19 pandemic on the time between blood culture collection and administration of antibiotics in the outpatient Department of Emergency Medicine in a single university hospital in Japan. The findings showed a decrease in the implementation rate of antibiotic administration within 3 hours after blood culture collection during the COVID-19 pandemic, with an increase as the number of COVID-19-positive patients decreased. However, AST intervention improved the implementation rate and maintained it during subsequent COVID-19 waves.
