Dual Antiplatelet Treatment up to 72 Hours After Ischemic Stroke Stratified by Risk Profile: A Post Hoc Analysis.

Stroke

January 2025

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, China (Y.Z., X.W., Y.G., W.C., H.Y., T.W., Y.Y., Q.Z., M.W., J.J., C.W., Yongjun Wang, Yilong Wang, Y.P.).

Background: Risk profile of recurrence may influence the effect of antiplatelet therapy. This study aimed to evaluate the efficacy and safety of clopidogrel-aspirin initiated within 72 hours after symptom onset for acute mild stroke or high-risk transient ischemic attack stratified by risk profile.

Methods: This is a secondary post hoc analysis of the INSPIRES (Intensive Statin and Antiplatelet Therapy for Acute High-risk Intracranial or Extracranial Atherosclerosis) randomized clinical trial that enrolled patients 35 to 80 years old with acute mild ischemic stroke or high-risk transient ischemic attack between 2018 and 2022.

Article Synopsis
  • Patchy data on litter decomposition in wetlands limits understanding of carbon storage, prompting a global study involving over 180 wetlands across multiple countries and climates.
  • The study found that freshwater wetlands and tidal marshes had more organic matter remaining after decay, indicating better potential for carbon preservation in these areas.
  • Elevated temperatures positively affect the decomposition of resistant organic matter, with projections suggesting an increase in decay rates by 2050; however, the impact varies by ecosystem type and highlights the need to recognize both local and global factors influencing carbon storage.

Article Synopsis
  • Tranexamic acid, an antifibrinolytic agent, was tested in a study on patients with intracerebral hemorrhage who had ongoing bleeding (spot signs) to assess its effect on hematoma growth when administered within 4.5 hours of onset.
  • A systematic review and meta-analysis were conducted, evaluating randomized trials comparing tranexamic acid to a placebo, specifically including 162 participants with follow-up imaging.
  • Results showed that tranexamic acid treatment did not significantly reduce hematoma growth compared to placebo, with a slightly lower growth rate in the treatment group, but overall outcomes suggested continued monitoring and assessment of safety was needed.

Past research on interspecies communication has shown that animals can be trained to use Augmentative Interspecies Communication (AIC) devices, such as soundboards, to make simple requests of their caretakers. The recent uptake in AIC devices by hundreds of pet owners around the world offers a novel opportunity to investigate whether AIC is possible with owner-trained family dogs. To answer this question, we carried out two studies to test pet dogs' ability to recognise and respond appropriately to food-related, play-related, and outside-related words on their soundboards.

Desired fertility measures are routinely collected and used by researchers and policy makers, but their self-reported nature raises the possibility of reporting bias. In this paper, we test for the presence of such bias by comparing responses to direct survey questions with indirect questions offering a varying, randomized, degree of confidentiality to respondents in a socioeconomically diverse sample of Nigerian women ([Formula: see text]). We find that women report higher fertility preferences when asked indirectly, but only when their responses afford them complete confidentiality, not when their responses are simply blind to the enumerator.

Metoclopramide to Prevent Pneumonia in Patients With Stroke and a Nasogastric Tube: Data From the PRECIOUS Trial.

Stroke

October 2024

Department of Neurology and Neurosurgery, Brain Center, University Medical Center Utrecht, Utrecht University, the Netherlands (W.M.S., J.C.d.J., H.R., H.B.v.d.W.).

Background: A randomized trial suggested that treatment with metoclopramide reduces the risk of pneumonia in patients with acute stroke and a nasogastric tube. We assessed whether this finding could be replicated in a post hoc analysis of the randomized PRECIOUS trial (Prevention of Complications to Improve Outcome in Elderly Patients With Acute Stroke).

Methods: PRECIOUS was an international, 3×2 partial-factorial, randomized controlled, open-label clinical trial with blinded outcome assessment assessing preventive treatment with metoclopramide, paracetamol, and ceftriaxone in patients aged ≥66 years with acute ischemic stroke or intracerebral hemorrhage and a National Institutes of Health Stroke Scale score ≥6.

Background: Treatment of acute stroke, before a distinction can be made between ischemic and hemorrhagic types, is challenging. Whether very early blood-pressure control in the ambulance improves outcomes among patients with undifferentiated acute stroke is uncertain.

Methods: We randomly assigned patients with suspected acute stroke that caused a motor deficit and with elevated systolic blood pressure (≥150 mm Hg), who were assessed in the ambulance within 2 hours after the onset of symptoms, to receive immediate treatment to lower the systolic blood pressure (target range, 130 to 140 mm Hg) (intervention group) or usual blood-pressure management (usual-care group).

Contamination of the environment by microplastics (MPs), polymer particles of <5 mm in diameter, is an emerging concern globally due to their ubiquitous nature, interactions with pollutants, and adverse effects on aquatic organisms. The majority of studies have focused on marine environments, with freshwater systems only recently attracting attention. The current study investigated the presence, abundance, and distribution of MPs and potentially toxic elements (PTEs) in sediments of the River Kelvin, Scotland, UK.

The clinical severity of sickle cell disease (SCD) is strongly influenced by the level of fetal haemoglobin (HbF) persistent in each patient. Three major HbF loci (BCL11A, HBS1L-MYB, and Xmn1-HBG2) have been reported, but a considerable hidden heritability remains. We conducted a genome-wide association study for HbF levels in 1006 Nigerian patients with SCD (HbSS/HbSβ0), followed by a replication and meta-analysis exercise in four independent SCD cohorts (3,582 patients).

The widespread consumption of pharmaceutical drugs and their incomplete breakdown in organisms has led to their extensive presence in aquatic environments. The indiscriminate use of antibiotics, such as sulfonamides, has contributed to the development of drug-resistant bacteria and the persistent pollution of water bodies, posing a threat to human health and the safety of the environment. Thus, it is paramount to explore remediation technologies aimed at decomposing and complete elimination of the toxic contaminants from pharmaceutical wastewater.

Background: Dual antiplatelet treatment has been shown to lower the risk of recurrent stroke as compared with aspirin alone when treatment is initiated early (≤24 hours) after an acute mild stroke. The effect of clopidogrel plus aspirin as compared with aspirin alone administered within 72 hours after the onset of acute cerebral ischemia from atherosclerosis has not been well studied.

Methods: In 222 hospitals in China, we conducted a double-blind, randomized, placebo-controlled, two-by-two factorial trial involving patients with mild ischemic stroke or high-risk transient ischemic attack (TIA) of presumed atherosclerotic cause who had not undergone thrombolysis or thrombectomy.

Early identification of genetic risk factors for complex diseases can enable timely interventions and prevent serious outcomes, including mortality. While the genetics underlying many Mendelian diseases have been elucidated, it is harder to predict risk for complex diseases arising from the combined effects of many genetic variants with smaller individual effects on disease aetiology. Polygenic risk scores (PRS), which combine multiple contributing variants to predict disease risk, have the potential to influence the implementation for precision medicine.

The persistence and recalcitrance of endocrine-disrupting chemicals (EDCs) in the environment have raised momentous concerns due to their carcinogenic, teratogenic, genotoxic, and cytotoxic effects on humans, animals, and plants. Unarguably, dibutyl phthalate (DBP) is one of the most ubiquitous EDCs because of its bioavailability in water, soil, and atmosphere. This study aims to investigate the efficiency of Agaricus bisporus laccase in the degradation of dibutyl phthalate (DBP) in laccase-mediator system.
