Because therapeutic cancer vaccines can, in theory, eliminate tumor cells specifically with relatively low toxicity, they have long been considered for application in repressing cancer progression. Traditional cancer vaccines containing a single or a few discrete tumor epitopes have failed in the clinic, possibly due to challenges in epitope selection, target downregulation, cancer cell heterogeneity, tumor microenvironment immunosuppression, or a lack of vaccine immunogenicity. Whole cancer cell or cancer membrane vaccines, which provide a rich source of antigens, are emerging as viable alternatives.

Research on virus/receptor interactions has uncovered various mechanisms of antibody-mediated neutralization against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, understanding of neutralization by antibodies targeting the silent face, which recognize epitopes on glycan shields, remains limited, and their potential protective efficacy in vivo is not well understood. This study describes a silent face neutralizing antibody, 3711, which targets a non-supersite on the N-terminal domain (NTD) of the spike protein.

Gut microbiota is an intricate microbial community containing bacteria, fungi, viruses, archaea, and protozoa, and each of them contributes to diverse aspects of host health. Nevertheless, the influence of interaction among gut microbiota on host health remains uncovered. Here, we showed that the interaction between intestinal fungi and bacteria shaped lung inflammation during infection.

Article Synopsis
  • This study examined the impact of valvular heart disease (VHD)-related heart failure (HF) in G20 countries over nearly three decades, from 1990 to 2019.
  • The findings showed a rising trend in VHD-related HF prevalence, with notable differences between nonrheumatic and rheumatic VHD cases across various countries, influenced by age and sociodemographic factors.
  • The results emphasize the urgent need for public health strategies to address the increasing burden of VHD-related HF, particularly among older populations.

NK/T-cell lymphoma (NKTCL) is a highly aggressive malignant tumour with a very poor prognosis, which often poses diagnostic difficulties due to the non-specificity of its clinical presentation. NK/T-cell lymphoma with eosinophilic hyperplasia syndrome is extremely rare. This article describes a patient with NKTCL misdiagnosed as vasculitis who presented with sinusitis, abdominal pain, anorexia, and lung shadows.

  • This study investigated the effectiveness and safety of anlotinib as a treatment for small cell lung cancer (SCLC) patients who also had brain metastases (BM), showing a poor prognosis.
  • An analysis of the ALTER1202 trial revealed that patients treated with anlotinib had significantly improved progression-free survival (3.8 months) and overall survival (6.1 months) compared to those receiving a placebo.
  • Anlotinib showed potential in delaying CNS progression and had a manageable side effect profile, with common serious adverse effects including increased lipase levels and hypertension.

Contactin-associated protein-like 4 (Cntnap4) is critical for GABAergic transmission in the brain. Impaired Cntnap4 function is implicated in neurological disorders, such as autism; however, the role of Cntnap4 on memory processing is poorly understood. Here, we demonstrate that hippocampal deficiency in female mice manifests as impaired cognitive function and synaptic plasticity.

Background The associations of oral contraceptive (OC) use with cardiovascular disease (CVD) and all-cause death remains unclear. We aimed to determine the associations of OC use with incident CVD and all-cause death. Methods and Results This cohort study included 161 017 women who had no CVD at baseline and reported their OC use.

Percutaneous endovascular biopsy (PEB) including forceps biopsy and catheter aspiration has been used to make a pretreatment diagnosis for pulmonary artery (PA) masses. This retrospective study aims to describe the procedure of PEB and compare the diagnostic yield of forceps biopsy and catheter aspiration for a definite diagnosis in patients with PA masses. All consecutive 22 patients (53 ± 14 years), 11 males and 11 females, who underwent PEB for pathologic confirmation between November 2018 and November 2022 were enrolled.

This is a case of congenital afibrinogenemia with multiple thrombotic and hemorrhagic events. His fibrinogen concentration was negatively correlated with thrombin time and prothrombin time and abnormally negatively correlated with plasma D-dimer levels. The individualized standard for fibrinogen concentration may help to balance thrombotic and hemorrhagic events for this disease.

The Coronavirus disease 2019 (COVID-19) pandemic has severely affected the lives of people around the world, especially some patients with severe chronic diseases. This study aims to evaluate the impact of the COVID-19 outbreak from December 2019 to April 2020 on treating patients with PH. A questionnaire regarding the medical condition of PH patients during the COVID-19 pandemic was designed by PH diagnostic experts in The First Affiliated Hospital of Guangzhou Medical University, China Respiratory Center.

The aim of this study is to provide evidence for the influencing factors of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus mutation by determining the impact of geographical and meteorological factors on SARS-CoV-2 transmission, and the different impacts of SARS-CoV-2 variant strains. From January 20 to March 10, 2020, we collected a number of daily confirmed new cases and meteorological factors in all cities and regions in China and Italy affected by the Alpha "variants of concern" (VOC). We also collected the daily confirmed cases of the Delta VOC infection in China and Italy from May 21 to November 30, 2021.

Article Synopsis
  • Abnormal endothelial function in the lungs plays a key role in pulmonary hypertension, with this study focusing on how different sizes of pulmonary arteries (PAs) contribute to this condition.
  • It was found that large proximal PAs predominantly rely on nitric oxide release for relaxation, while small distal PAs depend more on a process called endothelium-dependent hyperpolarization (EDH).
  • Chronic hypoxia disrupts EDH-mediated relaxation in small distal PAs by downregulating a protein called connexin 40 (Cx40), leading to increased pressure in the right ventricle, which is a significant factor in the development of pulmonary hypertension.

Background Heterozygous mutation in BMP (bone morphogenetic protein) receptor 2 is rare, but BMP cascade suppression is common in congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH); however, the underling mechanism of BMP cascade suppression independent of BMP receptor 2 mutation is unknown. Methods and Results Pulmonary hypertensive status observed in CHD-PAH was surgically reproduced in rats. Gremlin-1 expression was increased, but BMP cascade was suppressed, in lungs from CHD-PAH patients and shunted rats, whereas shunt correction retarded these trends in rats.
