Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.

Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.

Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.

The GM2 gangliosidoses, Tay-Sachs disease and Sandhoff disease, are devastating neurodegenerative disorders caused by β-hexosaminidase A (HexA) deficiency. In the Sandhoff disease mouse model, rescue potential was severely reduced when HexA was introduced after disease onset. Here, we assess the effect of recombinant HexA and HexD3, a newly engineered mimetic of HexA optimized for the treatment of Tay-Sachs disease and Sandhoff disease.

Background: Whether it is effective and safe to extend the time window of intravenous thrombolysis up to 24 hours after the last known well is unknown. We aimed to determine the efficacy and safety of tenecteplase in Chinese patients with acute ischemic stroke due to large/medium vessel occlusion within an extended time window.

Methods: Patients with ischemic stroke presenting 4.

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.

Purpose: To evaluate the consistency and agreement between portal venous pressure measured by fine-needle (F), portal vein catheterization (D), and hepatic vein balloon-occlusion (W) in decompensated cirrhotic patients with intrahepatic venovenous shunts (IHVS).

Materials And Methods: 156 consecutive patients planning to receive transjugular intrahepatic portosystemic shunt in our center were screened for study participation. The F/D/W were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R), and intraclass correlation coefficient (ICC), and for disagreement (error exceeding 20% of D) by Bland-Altman method.

Background: Currently, validated biomarkers for assessing hemorrhagic transformation (HT) after intravenous thrombolysis (IVT) are lacking. We aimed to validate a test combining GFAP (glial fibrillary acidic protein) and UCH-L1 (ubiquitin C-terminal hydrolase-L1) to indicate the absence of HT after IVT.

Methods: We prospectively enrolled consecutive patients with stroke treated with IVT from 16 hospitals.

Background: The infiltration of macrophages into the lungs is a common characteristic of perivascular inflammation, contributing to vascular remodeling in pulmonary hypertension (PH). Peli1 (pellino E3 ubiquitin-protein ligase 1) plays a critical role in regulating the production of proinflammatory cytokines and the polarization of macrophages in various diseases. However, the role of Peli1 in PH remains to be investigated.

Background: We aim to assess the efficacy of rapid local ischemic postconditioning (RL-IPostC) following successful reperfusion in patients with acute ischemic stroke with anterior circulation large vessel occlusion who underwent endovascular thrombectomy.

Methods: We conducted an ambidirectional cohort study with 78 prospectively enrolled patients with RL-IPostC and endovascular thrombectomy and 129 retrospectively enrolled patients with endovascular thrombectomy. The RL-IPostC procedure involved 5 cycles of 15-s balloon inflation and deflation in the ipsilateral internal carotid artery.

Somatic alterations in the oncogenic kinase AKT1 have been identified in a broad spectrum of solid tumours. The most common AKT1 alteration replaces Glu17 with Lys (E17K) in the regulatory pleckstrin homology domain, resulting in constitutive membrane localization and activation of oncogenic signalling. In clinical studies, pan-AKT inhibitors have been found to cause dose-limiting hyperglycaemia, which has motivated the search for mutant-selective inhibitors.

Article Synopsis
  • * Research shows that NF1-null melanomas rely on RAS for growth, and using a MEK inhibitor like avutometinib alone can increase RAS signaling instead of decreasing it.
  • * Combining MEK inhibition with SOS1 suppression effectively reduces RAS activity, induces cancer cell death, and suppresses tumor growth, highlighting a new strategy for treating NF1-mutant melanoma.

Invasive fungal infections (IFIs) pose a significant threat to immunocompromised individuals, leading to considerable morbidity and mortality. Prompt and accurate diagnosis is essential for effective treatment. Here we develop a rapid molecular diagnostic method that involves three steps: fungal enrichment using affinity-magnetic separation (AMS), genomic DNA extraction with silicon hydroxyl magnetic beads, and detection through a one-pot system.

Article Synopsis
  • - EPHB4 and RASA1 are essential for the formation and maintenance of lymphatic vessel (LV) valves during development, but how they interact in this process is not fully understood.
  • - The study used both genetically modified mice and human lymphatic endothelial cells to show that disrupting EPHB4 or RASA1 significantly impairs LV valve specification and development, which can be countered by targeting the Ras-MAPK signaling pathway.
  • - The findings indicate that proper function of EPHB4 and RASA1 is crucial for successful LV valve development, with potential implications for understanding lymphatic diseases or conditions related to valve dysfunction.

In order to investigate the influence of the CaO and fly ash (FA) dosage and proportion on the mechanical properties, durability, and microstructure of solidified sludge, freeze-thaw (F-T) cycles and dry-wet (D-W) cycles are conducted to study the change in appearance and the strength attenuation of CaO-FA solidified sludge. Low-field nuclear magnetic resonance (LF-NMR) is used to analyze the microstructure of the solidified sludge with various dosages and ratios of CaO-FA. The results demonstrate that the unconfined compressive strength (UCS) and direct shear strength of solidified sludge increase with the prolongation of the curing age.

  • Microplastics (MPs) contamination in marine environments poses ecological risks, particularly in the East China Sea (ECS), due to their interaction with other pollutants and harmful additives.
  • A study found high abundance of MPs in both bottom water and sediment, primarily made up of polyester, polyethylene, and polypropylene, indicating strong correlations between MP presence and levels of heavy metals and halogenated flame retardants.
  • The research suggests that MPs can act as carriers for pollutants, enabling their transport and co-settlement in marine environments, which highlights the need for better management and control of MP contamination.

Background: Although primary hyperparathyroidism (PHPT) is readily diagnosed biochemically and can be cured with low-risk surgery, it is often underrecognized and undertreated. Our objectives were to characterize, within our health system, how often patients with hypercalcemia were evaluated for PHPT and how often patients with PHPT underwent definitive treatment with parathyroidectomy.

Methods: Ambulatory patients aged 18 years or older seen at our health system between January 2018 and June 2023 with chronic hypercalcemia were identified from the medical record.
