Enteral nutrition support in patients with cancer: association of short-term prognosis and medical costs with inflammation.

Background: Enteral nutrition (EN) is commonly used for nutritional support in patients with cancer. Whether inflammation, one of the driving factors of malnutrition and cancer, affects the association between EN and short-term prognosis and medical costs in patients with cancer remains unclear. We aimed to investigate the association between EN and short-term prognosis of patients with cancer and the effect of inflammation on EN-associated medical costs.

Global burden of myocarditis from 1990 to 2021: findings from the Global Burden of Disease Study 2021.

Background: Myocarditis is a major public health, social, and economic issue. Currently, few studies have provided comprehensive analyses of the global burden of myocarditis based on GBD (Global Burden Disease) 2021. We therefore analyzed long-term trends in the global burden of myocarditis from 1990 to 2021, described risk factors, examined the impact of COVID-19 (coronavirus infection disease 2019), and predicted future trends to inform health policy development and healthcare resource allocation.

The case report of the impact of coach self-supportive behaviors on the communication effectiveness with depressed athletes: The mediating role of intrinsic motivation.

Rationale: Coach autonomy-supportive behaviors are a crucial factor in the communication effectiveness with athletes experiencing depressive moods. Therefore, clarifying the relationship between coach autonomy-supportive behaviors and the communication effectiveness with athletes experiencing depressive moods is of significant importance for promoting effective communication between coaches and athletes. This study employs in-depth interviews, questionnaires, and stepwise regression analysis, using purposive sampling to investigate coaches and athletes experiencing depressive moods from various regions, levels, genders, and sports in China.

Application of improved ant-lion algorithm for power systems.

An improved ant-lion algorithm is proposed to solve the load allocation problem to improve the efficiency of load allocation in the power system. The global search capability and optimization performance of the algorithm have been significantly improved by introducing elite weights and chaotic search mechanisms. The innovation of the research lies in not only optimizing economic goals, but also considering environmental goals, achieving dual optimization of economy and environment.

The weighted sum of powers in mean for estimating a change point in linear processes with random coefficients.

Let be a sequence of linear process based on dependent random variables with random coefficients, which has a mean shift at an unknown location. The weighted sum of powers in mean (WSPM, for short) estimator of the change point is proposed. The weak consistency, the rate of weak consistency and strong consistency for the WSPM estimator are established under some mild conditions.

Application of machine learning in acute upper gastrointestinal bleeding: bibliometric analysis.

Background: In the past decade, the application of machine learning (ML) in the clinical management of acute upper gastrointestinal bleeding (AUGIB) has received much attention and has become a hot research topic. However, no scientometric report has systematically summarized and outlined the research progress in this field.

Objective: This study aims to utilize bibliometric analysis methods to delve into the applications of machine learning in AUGIB and the collaborative network behind it over the past decade.

Cooperation resonance based on link strategy reinforcement learning and conformity.

We propose a game model that integrates reinforcement learning (RL) with link strategies and conformity behavior to investigate the emergence and maintenance of cooperation. The model operates on a lattice network with periodic boundaries and includes two types of nodes: RL nodes with link strategies and conformist nodes. Simulation results reveal a range of critical mass.

Global burden of low back pain and its attributable risk factors from 1990 to 2021: a comprehensive analysis from the global burden of disease study 2021.

Background: This study aimed to examine the evolving trends in the global burden of low back pain (LBP) from 1990 to 2021 and predicted disease burden until 2035.

Materials And Methods: LBP-related data were obtained from the Global Health Data Exchange (GHDx) query tool. All estimates and their 95% uncertainty intervals (UIs) were generated using DisMod-MR 2.

Partial thermal atomization of residual Ni NPs in single-walled carbon nanotubes for efficient CO electroreduction.

CO electroreduction (CORR) is an important solution for converting inert CO into high value-added fuels and chemicals under mild conditions. The decisive factor lies in the rational design and preparation of cost-effective and high-performance electrocatalysts. Herein, we first prepare a novel f-SWNTs-650 catalyst a facile partial thermal atomization strategy, where the residual Ni particles in single-walled carbon nanotubes (SWNTs) are partially converted into atomically dispersed NiN species.

Environmental taxes promote the synergy between pollution and carbon reduction: Provincial evidence from China.

Since its implementation in 2018, China's environmental tax has become a crucial mechanism in the nation's strategy for reducing environmental pollution. However, its synergistic effect between pollution and carbon reduction has not been adequately focused on and evaluated. This study employs the difference-in-differences (DID) model to analyze the impact of the environmental tax policy on the emissions of pollutant and CO as well as the synergistic effect between them.

Global, regional and country-specific burden of patella, tibia or fibula, or ankle fractures and its prediction to 2035: findings from global burden of disease study 2019.

Background: Bone fractures are a global public health issue and a major source of significant illness and financial hardship. However, to date, there is limited research on patella, tibia or fibula, or ankle fractures (FPTFA) disease burden.

Methods: Using the framework of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we conducted temporal trends of disease burden, effects of sex and socio-demographic index (SDI) on age standardized prevalence rate (ASPR) and age-period-cohort model.

Does import trade liberalization worsen residents' health? Evidence from China.

Health is important to human capital and national sustainable development. Based on the latest Chinese Family Panel Studies (CFPS), this paper uses the IVprobit model to test the impact of import trade liberalization on residents' health from the micro-individual perspective and further explores its mechanism. The results indicate that import trade liberalization brings hidden health costs, and that the negative effects on the health of people in eastern China or rural areas, people with a low education background, people under 60 years of age, and women are more significant.
