Preoperative inspiratory muscle training improves lung function prior to elective heart valve surgery and reduces postoperative lung function impairment and pulmonary complications: a randomised trial.

Question: What is the effect of 3 days of preoperative inspiratory muscle training (IMT) on lung function prior to heart valve surgery and on postoperative lung function and pulmonary complications compared with sham and no IMT?

Design: A three-arm, multicentre, randomised controlled trial with concealed allocation, intention-to-treat analysis and blinded assessment of some outcomes.

Participants: This study included 228 adults scheduled for heart valve surgery.

Interventions: The IMT group received 3 days of IMT at 30% maximal inspiratory pressure, the sham IMT group received the same but at 10% maximal inspiratory pressure and the control group received no IMT.

Enhanced Interfacial Electron Transfer in Photocatalyst-Natural Enzyme Coupled Artificial Photosynthesis System: Tuning Strategies and Molecular Simulations.

Laccase is capable of catalyzing a vast array of reactions, but its low redox potential limits its potential applications. The use of photocatalytic materials offers a solution to this problem by converting absorbed visible light into electrons to facilitate enzyme catalysis. Herein, MIL-53(Fe) and NH-MIL-53(Fe) serve as both light absorbers and enzyme immobilization carriers, and laccase is employed for solar-driven chemical conversion.

Unveiling the Effects of Carbon-Based Nanomaterials on Crop Growth: From Benefits to Detriments.

To systematically assess the impact of typical CNMs on the growth effects of cereal crops, we conducted a meta-analysis of 48 independent studies worldwide. The pooled results showed that shoot weight (13.39%) and antioxidant metabolite content (SOD: 106.

Risk factors of nosocomial infection in patients underwent artificial liver support system: a retrospective case-control study.

Background: Although nosocomial infection is one of the most discussed problems in patients undergoing artificial liver support system (ALSS) treatment, only few solutions have been proposed so far. This study aimed to explore the risk factors of nosocomial infection in patients treated with ALSS in order to aid in the development of future preventive measures.

Methods: This retrospective case-control study included patients treated with ALSS at the Department of Infectious Diseases, First Affiliated Hospital of xxx Medical University between January 2016 and December 2021.

Catalyst-Free Photochemical Activation of Peroxymonosulfate in Xanthene-Rich Systems for Fenton-Like Synergistic Decontamination: Efficacy of Proton Transfer Process.

Catalyst-free visible light assisted Fenton-like catalysis offers opportunities to achieve the sustainable water decontamination, but the synergistic decontamination mechanisms are still unclear, especially the effect of proton transfer process (PTP). The conversion of peroxymonosulfate (PMS) in photosensitive dye-enriched system was detailed. The photo-electron transfer between excited dye and PMS triggered the efficient activation of PMS and enhanced the production of reactive species.

Adaptive Posture-Balance Cardiac Rehabilitation Exercise Significantly Improved Physical Tolerance in Patients with Cardiovascular Diseases.

Cardiac rehabilitation (CR) requires more professional exercise modalities to improve the efficiency of treatment. Adaptive posture-balance cardiac rehabilitation exercise (APBCRE) is an emerging, balance-based therapy from clinical experience, but lacks evidence of validity. Our study aimed to observe and assess the rehabilitation effect of APBCRE on patients with cardiovascular diseases (CVDs).

Periodate activated by manganese oxide/biochar composites for antibiotic degradation in aqueous system: Combined effects of active manganese species and biochar.

Developing efficient catalysts for oxytetracycline (OTC) degradation is an ideal strategy to tackle environmental pollution, and advanced oxidation processes (AOPs) have been widely used for its degradation. However, the studies on the activation of periodate (PI) by biochar and its composites in recent years have been scarcely reported. In this study, we focused on the degradation of OTC by PI activation with manganese oxide/biochar composites (MnO@BC).

Biochar in the 21st century: A data-driven visualization of collaboration, frontier identification, and future trend.

The massive amounts of publication data are highly valuable, because in addition to the advancement in science, technology, and policy, such data can provide critical information and guidance on what have been published, what topical changes have evolved, and what are the trending fields deserving more attention. In the 21st century, biochar has played an indispensable role in the long-term global development strategies in response to "Carbon neutralization", "Agricultural management", and "Environmental restoration", and accumulated many high-quality publications. Herein, this study provides a new data-driven bibliometric analysis strategy and framework for mining the core content of massive literature data, and aims at bringing unique insights for the research prospects as well as opportunities of biochar.

The correlation between feeding intolerance and poor prognosis of patients with severe neurological conditions: a case-control study.

Background: This study aims to investigate the current status of feeding intolerance (FI) among patients with severe neurological conditions and to further determine the correlation between FI and their poor prognosis.

Methods: This study performed a retrospective analysis of the medical data of 58 patients from January 2017 and December 2017. Patients were divided into two groups according to modified Rankin Scale (mRS) scores.

Risk Factors and Predictive Model of Diarrhea Among Patients with Severe Stroke.

Objective: To investigate the risk factors and predictive model of diarrhea among patients with severe stroke.

Methods: The study analyzed the retrospective clinical data of patients with new-onset stroke who had been admitted to the intensive care unit at the Department of Neurology of X Hospital, between September 2017 and April 2018. All data were analyzed with a binary logistic regression, and a logistic regression equation was used to build a predictive model of diarrhea among patients with severe stroke.

Research on the cause of death for severe stroke patients.

Aims And Objectives: To explore the characteristics of mortality among severe stroke patients, analyse their causes of death and provide evidence for improving the survival rate of stroke patients.

Background: Stroke is an important fatal and disabling disease that poses a large burden on its patients, and its high death rates have caused substantial concern to the World Health Organization.

Design: A retrospective case-control study.
