Nurse-to-patient ratios and readiness for hospital discharge: A moderated mediation model.

AIM: To explore whether and to what extent, nurse-patient assessment differences mediate the association between nurse-to-patient ratios and readiness for hospital discharge, and examine whether nurse-patient characteristics moderate the indirect and/or direct effect of mediation model. DESIGN: A cross-sectional study was carried out from March 2021 to December 2022. METHODS: A total of 523 pairs of gastrointestinal cancer patients with PICC and their nurses were recruited. All the participants were invited to complete the general information questionnaire and the Readiness for Hospital Discharge Scale. Outcome measure was patient-reported readiness for hospital discharge. This study was reported according to the STROBE checklist. RESULTS: The patients reported a low level of readiness for hospital discharge. Nurse-patient assessment differences were positively associated with nurse-to-patient ratios but negatively associated with readiness for hospital discharge. Furthermore, nurse-patient assessment differences fully mediated the effect of nurse-to-patient ratios on readiness for hospital discharge, and age and gender of patients only moderated the indirect path of mediation model.

Global status of research on gastrointestinal cancer patients' quality of life: A bibliometric and visual analysis from 2003 to 2023.

Objective: To analyze the current research status, hotspots, and frontiers in the field of Gastrointestinal (GI) cancer and quality of life (QoL) through the bibliometrics method, and to provide references and guidance for future research. Methods: Literature related to GI cancer and QoL from April 1, 2003 to March 31, 2023 was retrieved from the Web of Science Core Collection database. CiteSpace 6.2.R1 was performed for collaboration analysis, keyword co-occurrence analysis, and document co-citation analysis. Results: A total of 1224 publications were included in this study. There has been a significant increase in the number of publications in this field over the past two decades. The United States, the Karolinska Institute and the University of Amsterdam, and Pernilla Lagergren are the most prolific country, institution, and author, respectively. The links between most of the research constituents were relatively thin (centrality <0.1). The keyword analysis indicates that the benefits of physical activity on QoL, the levels of psychological distress and its relationship with QoL, as well as the development and validation of QoL measurement tools have been the research hotspots. Open-label/double-blind trials exploring therapeutic interventions and more targeted new drugs or more effective drug combinations, and longitudinal studies determining the direction of the association between psychological distress and QoL at different time points, may be emerging trends in this field. Conclusion: The cooperation among countries, institutions, and authors in this field should be strengthened. In addition, the health benefits of light physical activity, interventions for QoL, trajectory and direction of the relationship between psychological distress and QoL may be the focus of future research.

Bibliometric and Visual Analysis of Global Research on Taurine, Creatine, Carnosine, and Anserine with Metabolic Syndrome: From 1992 to 2022.

Red meat and animal-sourced protein are often disparaged as risk factors for developing metabolic syndrome, while emerging research has shown the beneficial effects of dietary taurine, creatine, carnosine, and anserine which are all exclusively abundant in red meat. Thus, it is imperative to highlight the available evidence to help promote red meat as part of a well-balanced diet to optimize human health. In this study, a bibliometric analysis was conducted to investigate the current research status of dietary taurine, creatine, carnosine, and anserine with metabolic syndrome, identify research hotspots, and delineate developmental trends by utilizing the visualization software CiteSpace. A total of 1094 publications were retrieved via the Web of Science Core Collection from 1992 to 2022. There exists a gradual increase in the number of publications on this topic, but there is still much room for research papers to rise. The United States has participated in the most studies, followed by China and Japan. The University of Sao Paulo was the research institute contributing the most; Kyung Ja Chang and Sanya Roysommuti have been identified as the most prolific authors. The analysis of keywords reveals that obesity, lipid profiles, blood pressure, and glucose metabolism, as well as ergogenic aid and growth promoter have been the research hotspots. Inflammation and diabetic nephropathy will likely be frontiers of future research related to dietary taurine, creatine, carnosine, and anserine. Overall, this paper may provide insights for researchers to further delve into this field and enlist the greater community to re-evaluate the health effects of red meat.

Consumption frequencies of beverages and the hypertension risk in adults: a cohort study in China.

OBJECTIVE: To explore the associations between the consumption frequencies of alcohol, tea and sugar-sweetened beverages (SSBs) and the hypertension risk among Chinese adults. DESIGN: A longitudinal study of the effect of beverage consumption on hypertension risk. SETTING: Nine provinces in China, including Jiangsu, Hubei, Hunan, Guangxi, Guizhou, Liaoning, Heilongjiang, Shandong and Henan. PARTICIPANTS: The longitudinal data of the China Health and Nutrition Survey from 2004 to 2015 were used. A total of 4427 participants from 9 provinces were included at baseline. OUTCOME: First incidence of hypertension. RESULTS: During a mean follow-up of 8.7 years, 1478 participants developed hypertension. Alcohol consumption more than twice a week in young men (HR 1.86, 95% CI 1.09 to 3.18) or middle-aged men (HR 1.37, 95% CI 1.01 to 1.87) was associated with a higher hypertension risk. Middle-aged women who consumed tea frequently (HR 0.71, 95% CI 0.52 to 0.97), or young women who consumed SSBs less than once a week (HR 0.31, 95% CI 0.14 to 0.67) had a lower risk of hypertension. CONCLUSIONS: High-frequency alcohol consumption increased the risk of hypertension in men, and frequent tea consumption and low-frequency SSBs consumption were associated with lower risk of hypertension in women. Consumption frequency of beverages was also suggested to be considered in the prevention and control of hypertension.

Global research on cancer and sleep: A bibliometric and visual analysis of the last two decades.

Objective: The study aimed to analyze the research status, hotspots, and frontiers of global research on cancer and sleep through bibliometrics and provide references and guidance for future research. Methods: The literature regarding cancer and sleep from 2002 to 2022 was searched from the Web of Science Core Collection (WoSCC) database. CiteSpace 5.6.R3 was performed for visualization analysis. Results: A total of 1,172 publications were identified. The number of publications in the field has gradually increased over the past two decades. The United States had the most prominent contributions. Taipei Medical University and the University of California, San Francisco, and David Gozal were the most prolific institutions and author, respectively. The most published academic journal was Supportive Care in Cancer. The research hotspots can be summarized into the symptom cluster intervention for cancer survivors and the association between cancer and melatonin and/or obstructive sleep apnea (OSA). The complex interaction between cancer and sleep disruption and the influencing factors of sleep quality may be the emerging trends of research. Conclusion: This study systematically analyzed the hotspots and frontiers in the field of cancer and sleep and called for strengthening cooperation among countries, institutions, and authors. In addition, intervention measures for the cancer symptom cluster, the bioavailability of exogenous melatonin, the causal relationship between OSA and cancer, the mechanism of tumor-induced sleep disruption, the dose-response relationship between sleep duration and cancer risk, and the path relationship between sleep quality influencing factors may be the focus of future research.

Environmental remediation of Pb-Cd contaminated soil with organic phosphonic acids-saponin: Conditions, effectiveness, ecological risk and recovery.

Soil washing is a rapid and efficient method for heavy metals removal. In this study, a kind of novel environmentally friendly eluent is proposed, consisting of ethylenediamine tetra methylene phosphonic acid and saponin (E-S). In a response surface optimization design (RSOD), the operating parameters were optimized and ecological effects were investigated. Additionally, soil microbial diversity and composition were discussed. Finally, an optimal method for chelator recovery was presented. The single-factor and RSOD results showed that E-S had higher remediation efficiency for Pb-Cd contaminated soil with the best parameters of duration 240 min, temperature 40 °C, E/S ratio 1:1. Under these operating conditions, the removal rates of Pb and Cd were (72.2 ± 0.5)% and (61.2 ± 0.4)% for the artificially contaminated soil and (69.2 ± 0.1)% and (65.2 ± 0.2)% for in situ contaminated soil, respectively. The contents of Pb and Cd decreased from 562.36 mg/kg to 180.41 mg/kg and 80.96 mg/kg to 27.2 mg/kg respectively, and the soil ecological risk indexes reduced from 32% to 24% for Pb and 36%-27% for Cd. Owing to the efficient enrichment of Stenotrophomonas in soil, E-S has a potential of simultaneous removal effect on organic pollutants as well. Furthermore, the results revealed that E-S can be effectively recovered (>95%) by sodium sulfide precipitation.

Citric acid-based deep eutectic solvent (CA-DES) as a new soil detergent for the removal of cadmium from coking sites.

In order to solve the problem of soil pollution caused by excess heavy metals, cadmium (Cd), a novel soil-washing agent organic chelating acid-based deep eutectic solvent (OCA-DES), was investigated for the removal of Cd from the contaminated soil of coking plant. Four kinds of OCA-DES were prepared by mixing choline chloride (Ch-Cl) with four organic chelating acids (citric acid, oxalic acid, tartaric acid, and malic acid), respectively, to compare their washing efficiency of Cd from soil. The effects of washing operation conditions on the Cd removal efficiency were investigated. Side effects of citric acid-based deep eutectic solvent (CA-DES) on soil were analyzed using scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR). The results showed that CA-DES had the best Cd removal efficiency and could reach as high as 93.75%, under ideal conditions. CA-DES mainly washed extractable and reducible Cd. The CA-DES washing process has less side effects on soil and hardly eroded the soil or changed the mineral structure of the soil. The main roles of CA-DES washing Cd include (1) hydrogen bonds capturing Cd; (2) the carboxyl group(-COOH) forming soluble chelate with Cd; and (3) releasing H+ ions in exchange for Cd. This study demonstrates that CA-DES, a novel soil-washing agent, has excellent removal of cadmium from soil and is environment-friendly.

Interaction effect between overweight/obesity and alcohol consumption on hypertension risk in China: a longitudinal study.

OBJECTIVE: To explore the interaction effect between overweight/obesity and alcohol consumption on hypertension risk. DESIGN: A longitudinal study of the independent and combined effects of hypertension risk factors. SETTING: Twelve provinces in China, including Beijing Liaoning, Heilongjiang, Shanghai, Jiangsu, Shandong, Henan, Hubei, Hunan, Guangxi, Guizhou and Chongqing. PARTICIPANTS: Longitudinal data of China Health and Nutrition Survey, collected between 2011 and 2015, were used in this study. A total of 13 121 residents from 12 provinces were included and completed physical examinations and questionnaires at baseline. OUTCOME: First incidence of hypertension. RESULTS: Over a mean follow-up of 4 years, 690 incident hypertension cases were reported. After adjusting for age, gender, education level, marital status, physical activity, diabetes and smoking, high body mass index (BMI) and light drinking (OR=5.07, 95% CI 3.06 to 8.41), high waist circumference (WC) and light drinking (OR=4.81, 95% CI 2.92 to 7.91), high waist hip ratio and light drinking (OR=2.85, 95% CI 1.84 to 4.42) were the highest risk of all participants in the three combinations. Multiplicative interaction measures were statistically significant in overweight/obesity and drinking/light drinking/heavy drinking categories in men (p<0.05). Additive interactions were observed between high BMI and drinking in men (relative excess risk due to interaction=1.75, 95% CI 0.85 to 2.65, attributable proportion due to interaction=0.56, 95% CI 0.36 to 0.76, synergy index=6.43, 95% CI 1.02 to 28.84). CONCLUSIONS: Measures of body weight and size, particularly BMI and WC, appear to interact synergistically with alcohol consumption to increase the risk of hypertension in the Chinese population. Given that approximately 245 million people in China have hypertension, and that hypertension is a major cause of cardiovascular disease worldwide, our results may have implications for chronic disease prevention.

Effects of physical exercise on cognitive function of breast cancer survivors receiving chemotherapy: A systematic review of randomized controlled trials.

BACKGROUND: Cognitive impairment has a great negative impact on quality of life for breast cancer survivors. Emerging evidence suggested that physical exercise can improve cognitive function in order adults with Alzheimer's disease. However, less is known about the effects of physical exercise on cognitive function for breast cancer survivors. The purpose of this meta-analysis was to evaluate the effect of physical exercise on cognitive function in breast cancer survivors. METHODS: EMBASE, the Cochrane Library, Web of Science and PubMed were searched from the establishment of the databases to June 2021. Randomized controlled trials were included. All analysis were conducted using the Revman 5.3. RESULTS: 12 studies (936 participants) indicated that exercise improved self-reported cognitive function (MD 10.12, 95% CI [5.49,14.76], p < 0.0001), cognitive fatigue (MD -5.41, 95% CI [-10.31,-0.51], p = 0.03) and executive function (MD -13.63, 95% CI [-21.86,-5.39], p = 0.0001). CONCLUSION: Physical exercise can improve cognitive function for breast cancer survivors, particularly in self-reported cognitive function, and executive function. Future studies need to explore the effect of exercise on cognitive function from the frequency and duration of exercise.

Gender differences in the relationships between housework and metabolic markers: a longitudinal cohort study in China.

BACKGROUND: Metabolic syndrome has become a major health threat throughout the world, but there are few studies that focus on the effects of housework on human metabolism. This study explores the association between housework and metabolic markers and examines whether there are gender differences in the relationship of housework intensity on these markers. METHODS: We obtained data for 2,624 participants from the China Health and Nutrition Survey and used binary logistic regression to analyze the association between housework and metabolic markers (triglycerides, high- and low-density lipoprotein cholesterol, hemoglobin, blood glucose, cholesterol, and blood pressure). RESULTS: We observed no association between housework and metabolic markers for men. However, we find that women who engaged in housework had a higher risk of triglycerides than those who did not (OR=1.16, 95% CI: 1.16, 4.25). Compared with low-intensity, we also find that women who performed moderate- and high-housework intensity had a higher risk of triglycerides (moderate-intensity: OR=1.78, 95% CI: 1.14, 2.78; high-intensity: OR=1.91, 95% CI: 1.22, 2.98), MetS (OR=1.54, 95% CI: 0.98, 2.43; OR=1.68, 95% CI: 1.07, 2.66), pre-hypertension (OR=1.68, 95% CI: 1.08, 2.62; OR=1.63, 95% CI: 1.04, 2.55), and obesity (OR=1.65, 95% CI: 1.01, 2.70; OR=1.66, 95% CI: 1.01, 2.72). CONCLUSION: In women, we find that housework is positively associated with the metabolic markers, triglycerides, MetS, and pre-hypertension. However, we did not find evidence that this relationship exists in men, f or any biomarkers we considered. One possible explanation is that people who engage in high-intensity housework are more stressed and sleep less, which could be a mechanism by which housework becomes associated with metabolic disease.

Surface plasmon resonance biosensor based on graphene and grating excitation.

A surface plasmon resonance biosensor based on a graphene-decorated grating excitation structure is proposed in this paper. The biosensor consists of a three-layer structure, including a graphene layer, a grating layer, and a high refractive index layer. The material of the grating layer is silica. The graphene is physically deposited on the grating ridges. An incident light with transverse magnetic polarization is used to excite surface plasmons in the mid-infrared spectral region, which is highly localized at both ends of the graphene layer. The property of the sensor is improved by the high refractive index dielectric layer, which enhances the absorption of incident light and increases the depth of the spectra. The finite-difference time-domain method is used to simulate the property of the sensor. The structure of the sensor could be optimized by changing the structural parameters and comparing the simulation results. The effective refractive index (RI) on the surface and the wavelength of the reflective resonance absorption peak will be changed when the surface of graphene adsorbs the surrounding analyte. The results show that the relationship between the analyte RI and the resonance wavelength is linear. The measurement range of analyte RI is 1-1.8, and the sensitivity is 2780 nm/RIU.
