Grading magnetic resonance imaging signs for diagnosing invasive placenta accreta spectrum disorders.

Introduction: Placenta accreta spectrum (PAS) disorders result from abnormal placental attachment, leading to varying degrees of myometrial invasion. Magnetic resonance imaging (MRI) plays a crucial role in assessing the depth and extent of placental invasion. This study aims to evaluate the correlation between quantified MRI findings and the diagnosis of PAS, as classified according to the FIGO system.

Serum uric acid, body mass index, and cardiovascular diseases: A multiple two-step Mendelian randomization study.

Background And Aims: A number of health issues, including high serum uric acid (SUA) and cardiovascular disease (CVD), have been linked to obesity based on observational evidence, though it's currently unclear how these issues are causally related. In order to determine whether obesity mediates this association, we set out to investigate the causal relationship between SUA, obesity, and CVD.

Methods And Results: From publicly available genome-wide association studies, we acquired instrumental variables that had a strong correlation to SUA and body mass index (BMI).

Establishment of Human Pituitary Neuroendocrine Tumor Derived Organoid and Its Pilot Application for Drug Screening.

Context: Precision medicine for pituitary neuroendocrine tumors (PitNETs) is limited by the lack of reliable research models.

Design: From July 2019 to May 2022, a total of 32 human PitNET specimens were collected for the establishment of organoids with an optimized culture protocol.

Malignant Struma Ovarii (Papillary Carcinoma) with Hyperthyroidism: A Case Report and Literature Review.

Malignant struma ovarii (MSO) is an extremely rare monodermal ovarian teratoma. Preoperative diagnosis and intraoperative freezing diagnosis are exceedingly difficult due to the rarity of the disease and its clinically noncharacteristic manifestations with less than 200 reports in the current literature. In this paper, a case of MSO (papillary carcinoma) with hyperthyroidism was discussed in terms of its epidemiology, clinicopathology, molecular features, treatment, and prognosis.

Survival Benefits of Radiotherapy and Surgery in Lung Cancer Brain Metastases with Poor Prognosis Factors.

Background: Radiotherapy and surgery are the standard local treatments for lung cancer brain metastases (BMs). However, limited studies focused on the effects of radiotherapy and surgery in lung cancer BMs with poor prognosis factors.

Methods: We retrospectively analyzed 714 patients with lung cancer BMs.

Epidemiological and clinical characteristics of congenital pseudarthrosis of the tibia in China.

Background: Congenital pseudarthrosis of the tibia (CPT) is a refractory and rare disease. Because of its extremely low incidence, little is known about its clinical features. In this retrospective study, we aim to analyze the clinical characteristics of patients with CPT.

Red Cell Distribution Width to Platelet Ratio Is Associated with Increasing In-Hospital Mortality in Critically Ill Patients with Acute Kidney Injury.

Background: Inflammation plays a key role in the pathophysiology and progression of acute kidney injury (AKI). Red cell distribution width (RDW) to platelet ratio (RPR) is a novel inflammatory index, and its prognostic effect on critically ill patients with AKI is rarely investigated. This work is aimed at investigating the association between RPR and in-hospital mortality in these patients.

Trauma-induced complete pacemaker lead fracture 8 months prior to hospitalization: A case report.

Trauma-induced complete lead fracture is a rare complication of pacemaker implantation. Only a few cases have been previously reported. Common treatment included replacement of pacemaker and/or extraction of fractured lead.

LCZ696 Possesses a Protective Effect Against Homocysteine (Hcy)-Induced Impairment of Blood-Brain Barrier (BBB) Integrity by Increasing Occludin, Mediated by the Inhibition of Egr-1.

Homocysteine (Hcy) is a non-essential amino acid produced from methionine. It has been reported that high concentrations of Hcy are related to the pathogenesis of neurodegenerative diseases and induce the disruption of the blood-brain barrier (BBB) by triggering oxidative stress and inflammation. LCZ696 is a novel antihypertensive agent that has been recently reported to possess promising anti-inflammatory properties.

Protective effect of exosomes derived from bone marrow mesenchymal stem cells on rats with diabetic nephropathy and its possible mechanism.

Objective: To investigate the effect of exosomes derived from bone marrow mesenchymal stem cells (BMMSC-Exos) on diabetic nephropathy (DN) rats and its possible mechanism.

Methods: Thirty rats were divided into the following three groups of 10 rats each: the NC group (normal rats), the DN group (rats with DN), and the BM group (DN rats injected with BMMSC-Exo). Blood glucose level, renal function, blood lipid level, and plasma viscosity of the rats were detected.

Role of exosomal miRNAs in brain metastasis affected by radiotherapy.

In oncogenesis and development of malignant tumor, microRNAs (miRNAs) regulate the complex gene expression associated with the tumor pathogenesis. Currently, only few studies have been conducted to identify miRNAs and the potential pathways involved in the pathogenesis of brain metastasis in patients who underwent radiotherapy, especially miRNAs in the plasma exosomes. Therefore, this study is aimed to use small RNA analysis to identify miRNAs and their potential target genes in plasma exosomes during the initiation and development of brain metastasis in patients who underwent radiotherapy.

GPR120 Agonist GW9508 Ameliorated Cellular Senescence Induced by ox-LDL.

Oxidized low-density lipoprotein (ox-LDL)-induced endothelial senescence is involved in the pathogenesis of atherosclerosis and many cardiovascular diseases. G-protein-coupled receptor 120 (GPR120), a type of orphan G-protein-coupled receptors (GPRs), plays a vital role in mediating anti-inflammatory and insulin-sensitizing effects. The biological function of GPR120 in vascular endothelial cells is largely unknown.

Tocilizumab exerts anti-inflammatory activity in six critically ill COVID-19 patients: a retrospective analysis.

Background: Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic, affecting countries across the globe. With no current vaccine, treatment is still a critical intervention for minimizing morbidity and preventing disease-specific mortality. This study aimed to assess the clinical outcomes of critically ill COVID-19 patients using Tocilizumab treatment to provide recommendations for the treatment of COVID-19 patients with severe disease.

Correlation of intensity-modulated radiation therapy at a specific radiation dose with the prognosis of nasal mucous damage after radiotherapy.

Objective of the present study was to investigate the tolerant radiation dose of nasal mucosa by observing and analyzing patients who received intensity-modulated radiation therapy (IMRT). Patients with nasopharyngeal carcinoma (N = 66) were selected for this study. The modified saccharin assay, endoscopy test, magnetic resonance imaging, and sino-nasal outcome test-20 (SNOT-20) survey were performed for the patients before and at 0 (T0), 3 (T1), 6 (T2), and 12 (T3) months after radiotherapy.

Identification of miRNA signatures in serum exosomes as a potential biomarker after radiotherapy treatment in glioma patients.

Despite development in therapies, the high recurrence and low positivity of biomarkers for diagnosis still result in glioma with high mortality. In this study, we aimed to identify a potential miRNA signature to evaluate the effect of radiotherapy in glioma patients. MicroRNA (miRNA) sequencing was performed on miRNAs isolated from serum exosomes in a cohort of glioma patients before and after radiotherapy.
