The first available serum homocysteine measurement within 24 h of hospital arrival was analyzed continuously and by cohort-derived tertiles. The primary outcome was neurocognitive dysfunction documented within 24-48 h before discharge and adjudicated independently by two reviewers blinded to homocysteine levels; standardized cognitive instruments were not systematically available. Logistic regression was sequentially adjusted for demographic, renal, neurological, neuroimaging, and cerebrovascular phenotype-related factors.

Here, we describe a standardized protocol for multimodal assessment of RLS-related ischemic brain injury in a clinically selected cohort. The workflow includes patient screening, exclusion of major vascular and systemic factors that could independently contribute to brain parenchymal injury, contrast-enhanced transcranial Doppler ultrasound (c-TCD) confirmation and shunt grading, brain magnetic resonance imaging (MRI) classification, transthoracic and/or transesophageal echocardiographic anatomical assessment, structured data extraction, and dataset cleaning. To improve reproducibility, the protocol also standardizes key coding steps, including shunt-grade harmonization, classification of RLS as simple or complex, and interpretation of D-dimer values reported below the assay threshold. Using this workflow, a harmonized analytic cohort of 60 RLS-positive patients was established. MRI identified 23 MRI-negative and 37 MRI-positive patients. Representative analyses showed that MRI-positive findings were more frequent in patients with greater shunt burden and more complex anatomical phenotypes. This protocol provides an operational model for incorporating c-TCD, MRI, echocardiography, and structured clinical parameters into the evaluation of MRI-defined ischemic brain injury in RLS-positive patients. It should be interpreted as a workflow for standardized multimodal phenotyping rather than as a standalone physiologic assessment of all clinically significant or hypoxemia-related RLS.</p>","PeriodicalId":48787,"journal":{"name":"Jove-Journal of Visualized Experiments","volume":" 236","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This scoping review aimed to map perioperative interventions used to prevent POCI in older surgical patients and characterize how cognitive outcomes are defined, assessed, and prioritized.

Multicomponent non-pharmacological interventions showed the most consistent signal for reducing postoperative delirium, whereas findings for individual pharmacological and technical strategies were inconsistent.

However, conventional isolation methods are laborious and tend to favor dominant host-phage pairs, limiting the diversity of recoverable phages. Expanding the collection of phages is therefore a critical step toward advancing phage-based therapies. To achieve effective isolation outcomes, it is essential to systematically screen environmental samples against a broad range of host strains under standardized conditions. The efficiency of phage recovery depends on several factors, including enrichment strategies, host range coverage, and infection dynamics. To address these challenges, we have developed a streamlined protocol that integrates liquid culture enrichment, polyethylene glycol (PEG)-mediated concentration, high-throughput spot screening on multiple host bacterial lawns, and subsequent streak purification for clonal isolation. This approach enables simultaneous screening of environmental samples against multiple pathogens in a single experimental setup, improving isolation efficiency. Notably, it enhances the recovery of phages with diverse host ranges. Our integrated workflow can reduce manual effort and material consumption and shorten the isolation period compared with conventional methods. This robust and evidence-based method accelerates the discovery of phages with potential applications in therapy and biocontrol. We anticipate that this protocol will prove particularly useful for building phage biobanks, preparing personalized phage therapeutics, and conducting large-scale environmental phage mining.

Furthermore, these technologies aid in the conservation, preservation, and dissemination of genetic material from individuals with superior characteristics. The genetic rescue of selected individuals has led to numerous studies in domestic species aiming to extrapolate the findings to other animal populations or specific individuals. One such approach is through the use of somatic cell nuclear transfer (SCNT), or cloning, which is used to produce embryos with genetic material identical to that of an existing specimen. Among the limitations of this technique is the restricted availability of oocytes from wild animals. Thus, as an alternative, interspecific somatic cell nuclear transfer (iSCNT) emerged using a somatic cell (karyoplast) from the species to be cloned as a nuclear donor and its insertion into an enucleated oocyte (cytoplast) obtained from a species belonging to a different order or taxon. This approach makes it possible to obtain viable cloned embryos. In Brazil, there are nine species of deer, and many of them are endangered due to indiscriminate hunting, habitat loss, and other causes. The red brocket deer (Mazama americana) is one of the species suffering from these conditions.
