Tracheal intubation is an indispensable mean of life support in the rescue of critically ill patients, which can effectively improve patients' hypoxemia and tissue hypoxia and promote oxygenation function. Unplanned tracheal extubation is one of the common and serious complications in patients with mechanical ventilation, and improper catheter fixation is an independent risk factor leading to unplanned extubation. Therefore, good fixation measures are essential to prevent unplanned extubation. This study introduces the design and use method of a utility model of endotracheal tube fixation belt, which effectively improves the fixation quality of endotracheal tube and patient comfort in tracheal intubation (气管插管是抢救危重症患者不可或缺的生命支持手段, 其能够有效改善患者的低氧血症和组织缺氧, 促进氧合功能。非计划性气管拔管是机械通气患者中常见且严重的并发症之一, 导管固定不当是导致非计划性拔管的独立风险因素, 因此, 良好的固定措施对于预防非计划性拔管至关重要。本研究介绍了一款实用新型气管插管固定寸带的设计和使用方法, 其有效提高了气管插管的固定效果, 同时减轻了医护人员的工作负担, 提高了工作效率, 增加了患者的舒适性。)

The prevalence of chronic kidney disease (CKD) is gradually increasing in the elderly population. At the same time, frailty has become one of the research hotspots in the field of geriatrics. Bibliometric analyses help to understand the direction of a field. Therefore, this study aimed to analyze the status and emerging trends of frailty in CKD patients. The Web of Science Core Collection (WoSCC) database was screened for relevant literature published between 1 January 2000 and 31 December 2021. Next, publications were analyzed for information including authors, journals, cited references, citing journals, institutions, countries and regions, high-frequency keywords and co-citations using VOSviewer, Microsoft Excel, and R software. A total of 2223 articles were obtained, from which 613 relevant articles were selected based on title and abstract screening. There was an upward trend in the number of annual publications and Johansen KL was considered the most contributing author in the field. The Clinical Journal of the American Society of Nephrology was the most productive research journal. Johns Hopkins University is the most published organization. The United States is the global leader in the field and contributes the most to research. Research hotspots focus on epidemiological studies of frailty and frailty intervention. This study presents a comprehensive bibliometric analysis of CKD and frailty research. Key findings highlight the current focus on early screening and assessment of frailty in CKD patients, as well as physical function interventions in frail patients. [ABSTRACT FROM AUTHOR]

Comprehensive Summary: Axially chiral biaryls represent the most important class of atropisomers, and they widely exist in natural products and biologically active molecules. They also constitute a unique scaffold for chiral ligands and catalysts in organic synthesis. The development of synthetic methods to obtain such chiral compounds has received widespread attention, among which catalytically atroposelective ring‐opening of configurationally labile compounds represents one of the most attractive strategies. Various substrates with strained cyclic structures, such as the renowned Bringmann's lactones, can undergo asymmetric transformation into stable atropisomers. Known advancement primarily relies on metal catalyst combined with well‐designed chiral ligands, the approaches utilizing organocatalysis as a critical resolution strategy are notably scarce. In this study, we disclosed a N‐heterocyclic carbene (NHC)‐catalyzed asymmetric ring‐opening reaction of biaryl lactams via direct atroposelective nucleophilic activation. The optimized bulky carbene catalyst ensures that the reaction can proceed under mild conditions, affording the desired product with good to excellent yields and atroposelectivity.

Background: Limited literature has addressed the impact of nut consumption in mitigating frailty. This study aimed to investigate the association between nut consumption and frailty among Americans aged above 60 years, employing two 24‐h dietary recalls for analysis. Methods: The data sets of the National Health and Nutrition Examination Survey (NHANES) (2003–2018) and the Food Patterns Equivalents Database were utilised for a weighted multiple logistic regression model to evaluate the association between nut consumption and frailty in elderly adults. Furthermore, a restricted cubic spline model was employed to investigate the nonlinear relationship between nut intake and frailty. Besides, stratified and interaction analyses were conducted to explore the sensitivity of nut consumption in reducing the risk of frailty in diverse subgroups. Results: The research study comprised 10,033 individuals aged 60 years or above, of whom 3591 were classified as frailty and 5302 consumed nuts. In the multivariate logistic regression analysis that adjusted for covariates, the weighted multivariate adjusted odds ratios demonstrated that the prevalence of frailty was lower in the nut intake group than in nonconsumers. The stratified analysis indicated that nearly all subgroups who consumed nuts had a significantly lower risk of frailty compared to nonconsumers, and an interaction was observed between nut intake and nonhypertensive populations. The optimal threshold for nut intake to decrease the risk of frailty was identified as 1.02 ounces. Conclusions: The study concluded that nut consumption has a constructive impact on averting frailty in elderly adults, particularly in nonhypertensive individuals. Nut intake of ~1.02 ounces per day is advantageous in improving the quality of life in elderly adults. Key points: This study investigated the impact of nut consumption on frailty among American seniors aged over 60.A lower prevalence of frailty was observed in nut consumers in the National Health and Nutrition Examination Survey database.Almost all subgroups consuming nuts reaped advantages, with nonhypertensive individuals markedly standing out.Optimal nut intake to reduce frailty risk was found to be ~1.02 ounces daily.
