Incineration is an effective method for reducing and safely treating municipal solid waste. However, microplastics (MPs) inevitably remain in the bottom ash, potentially introducing new pollution risks during subsequent treatment processes. This study conducted an analysis of the accumulation and release potential of MPs in bottom ash samples collected from 4 municipal solid waste incineration plants in Zhejiang, China.

This challenge becomes increasingly formidable when dealing with the vast radiomic features obtained from low-dose computed tomography, a lung cancer screening technique being rolling out in many areas of the world. Consequently, this study proposed the Altruistic Seagull Optimization Algorithm (AltSOA) for the selection of radiomic features in predicting the malignancy risk of pulmonary nodules.

To this end, several non-emissive iridium(III) complexes [Ir(C-N) (H O) ] OTF (C-N denotes various cyclometalated ligands) were designed and synthesized. These complexes were tested for attaching a protein by coordinating to H/X (HisMet, HisHis, and HisCys) that are separated by i and i+4 in α-helix.

They emit sulfur-containing odors and serve as an important sink for a new type of pollutant called microplastics (MPs). This study focused on the initial stage of anaerobic degradation to establish the relationship between the release of MPs and odor generation.

Background: The number of patients undergoing percutaneous coronary intervention (PCI) procedures is increasing along with the number of studies involving guidelines, prognostic assessments, and cardiac rehabilitation related to PCI strategies. However, fewer studies have reported the mapping of knowledge structure and hotspot analysis in this field. Our goal was to discuss and analyze the current status, hot spots and developmental trends associated with research into the prognosis of patients undergoing PCI, and to provide reference for PCI-related research.

The environmental impact of microplastics (MPs) formed from landfill has not been gained enough attention. This research investigated the characteristics of the MPs occurrence in landfills through field sampling. It shows that the MPs abundance in the landfill surface soil and non-landfill areas can reach 3573 items·g and 3041 items·g, respectively.

With the evolution and development of the concepts of medicine, research concerning precision medicine and precision nursing is constantly expanding and deepening, creating new challenges and opportunities for the nursing practice of enhanced recovery after surgery (ERAS). In this paper, we reviewed the current status of research on precision nursing for ERAS, giving an overview of the application status of precision nursing in ERAS from the perspectives of precision nursing assessment, precision symptom management, precision nutrition support, and precision health education and nursing follow-up. In addition, we analyzed the challenges and their solutions for further promotion and application of precision nursing in ERAS, including strengthening the basic professional knowledge and skills, building a nursing information platform, and actively applying new tools and technologies.

Objectives: To investigate the interaction of gene polymorphism with body mass index (BMI) and alcohol consumption on the prognosis of Uyghur patients with ischemic heart failure (IHF).
Methods: A total of 205 Uyghur patients with IHF admitted in Urumqi Friendship Hospital from June 2014 to June 2017 were enrolled; 200 age and sex-matched healthy Uyghur physical examiners in the hospital were enrolled as healthy controls. The gene +1267 polymorphism was detected by PCR.
Background: Interferon-α-1b, interleukin-2 combined with thalidomide (ITI) improved the outcome and prognosis of some acute myeloid leukemia (AML) patients, but the cases was insufficient. This study observed the efficacy and safety of this regimen in the treatment of numbers of AML patients in various disease states.
Methods: Starting in January 2014, patients with AML (n=188) were treated with ITI regimen, including 60 refractory/relapses patients in group A, 40 patients in group B remained minimal residual disease-positive (MRD) or changed from negative to positive again after consolidation therapy, and 88 patients in group C with initial complete remission of AML received the ITI treatment after routine consolidation therapy.
Aiming at the problem that the single CT image signal feature recognition method in the self-diagnosis of diseases cannot accurately and reliably classify COVID-19, and it is easily confused with suspected cases. The collected CT signals and experimental indexes are extracted to construct different feature vectors. The support vector machine is optimized by the improved whale algorithm for the preliminary diagnosis of COVID-19, and the basic probability distribution function of each evidence is calculated by the posterior probability modeling method.

Accurate segmentation of ground-glass opacity (GGO) is an important premise for doctors to judge COVID-19. Aiming at the problem of mis-segmentation for GGO segmentation methods, especially the problem of adhesive GGO connected with chest wall or blood vessel, this paper proposes an accurate segmentation of GGO based on fuzzy c-means (FCM) clustering and improved random walk algorithm. The innovation of this paper is to construct a Markov random field (MRF) with adaptive spatial information by using the spatial gravity Model and the spatial structural characteristics, which is introduced into the FCM model to automatically balance the insensitivity to noise and preserve the effectiveness of image edge details to improve the clustering accuracy of image.

Objective: Named entity recognition (NER) is a key and fundamental part of many medical and clinical tasks, including the establishment of a medical knowledge graph, decision-making support, and question answering systems. When extracting entities from electronic health records (EHRs), NER models mostly apply long short-term memory (LSTM) and have surprising performance in clinical NER. However, increasing the depth of the network is often required by these LSTM-based models to capture long-distance dependencies.
