Article Abstract
Background: Sleep disruption, a common symptom among patients requiring cardiovascular surgery, is a potential risk factor for the development of postoperative delirium. Postoperative delirium is a disorder of acute disturbances in cognition associated with prolonged hospitalization, cognitive decline, and mortality.
Objective: The aim of this study was to evaluate the feasibility and acceptability of using polysomnography (PSG) to capture sleep in patients with scheduled cardiothoracic surgery.
Methods: Wireless limited PSG assessed sleep at baseline (presurgery at home), postoperatively in the intensive care unit, and at home post hospital discharge. Primary outcomes were quality and completeness of PSG signals, and acceptability by participants and nursing staff.
Results: Among 15 patients, PSG data were of high quality, and mean percentage of unscorable data was 5.5% ± 11.1%, 3.7% ± 5.4%, and 3.7% ± 8.4% for baseline, intensive care unit, and posthospitalization measurements, respectively. Nurses and patients found the PSG monitor acceptable.
Conclusions: Wireless, limited PSG to capture sleep across the surgical continuum was feasible, and data were of high quality. Authors of future studies will evaluate associations of sleep indices and development of postoperative delirium in this high-risk population.

Food spoilage poses a global challenge with far-reaching consequences for public health, economic stability, and environmental sustainability. Conventional analytical methods for spoilage detection though accurate are often cost-prohibitive, labor-intensive, and unsuitable for real-time or field-based monitoring. Microfluidic paper-based analytical devices (μPADs) have emerged as a transformative technology offering rapid, portable, and cost-effective solutions for food quality assessment.

Neurogenic bladder and lower urinary tract (LUT) dysfunctions encompass a wide variety of urinary disorders resulting from nervous system impairments. Unfortunately, conventional treatments are still limited and can have significant complication rates, especially when stent implantations or other surgical procedures are involved. Therefore, there is a critical need to develop novel therapeutic strategies and pharmacological approaches to address these challenging urological conditions.

Wearable sweat sensors offer noninvasive health monitoring through multiplexed biomarker analysis, delivering real-time diagnostics with continuous operational capability. However, chronic cutaneous interface hydration during prolonged monitoring induces adhesive delamination phenomena that manifest as signal attenuation, which fundamentally limits their clinical reliability. To address this challenge, we developed a thermodynamically adaptive polymer interface combining three functional components: mussel-inspired catechol moieties for moisture-tolerant adhesion, hydrophobic acrylates ensuring mechanical stability, and N-isopropylacrylamide enabling thermal responsiveness.

Natural killer (NK) cells can swiftly and efficiently kill tumor cells with low toxicity and show great potential as anticancer agents. However, the hostile tumor microenvironment (TME) reduces the number and functionality of NK cells, leading to tumor progression and the limited therapeutic effect of adoptively transferred NK cells, especially in solid tumors. Here, via mussel-inspired chemistry and targeted antibody modification strategies, functional piezoelectric nanoparticles are designed to target NK cells, named as αCD56-P@BT (for human) or αNK1.

The exponential growth of data in the information era has pushed conventional optical communication technology to its limitations, including inefficient spectral utilization, slow data rate, and inherent security vulnerabilities. Here, a transformative high-speed organic spectral wireless communication (SWC) technology enabled by a flexible, miniaturized, and high-performance organic hyperspectrometer is proposed that integrates ultrahigh-speed data transmission with hardware-level encryption. By synergistically combining organic photodetector arrays with tunable responsivities and spectral-tunable organic filters, the organic hyperspectrometer achieves a broad spectral detection range of 400 to 900 nm, resolution of 1.
