A retrospective Analysis of Intoxicated Patients Admitted to the Intensive Care Unit: A Single-Institution Assessment in the Post-Pandemic Period

引用

Journal of Biosciences and Medicines 2024年第3期12卷 159-167页

作者： Müge Arikan Abdullah Yeşilkaya Büşra Nur taşdelen İbrahim Özyiğit Department of Anesthesia and Intensive Care Faculty of Medicine Karabuk University Karabuk Turkey

Background: The aim of this study was to evaluate the clinical and epidemiological characteristics of patients with acute intoxication admitted to the Intensive Care Unit (ICU). Material and Methods: An observational retrospective study was conducted on intoxicated patients who admitted to ICU between January 2022 and January 2024. Data were collected from the patients medical records. The demographic characteristics, causes of intoxications, clinical parameters, the mean stay in the ICU, treatment modalities and prognosis were recorded. results: A total of 2875 critically ill patients were admitted during the study period, and 109 (3.79%) of them were acute intoxications. Their mean of ages was 38.09 ± 12.29. The female-to-male ratio was 1.37/1. Drugs were found to be the primary cause (62.39%) of intoxications, and analgesics, antidepressants, and antibiotics were the most frequent agents. Suicidal attempts were present in 66 patients, most of them were female (62.13%) and between 17 - 24 years (40.91%). The other common causes of intoxications were carbon monoxide (CO) (22.02%), methyl/ethyl alcohol (8.26%) and mushroom (5.50%). The mean stay in the ICU was 2.69 ± 0.89 days. Mechanical ventilation was applied to 10 of our patients. renal replacement therapy was required in 6 patients. Despite all treatments, 6 of our patients died, and we found the mortality rate to be 5.50%. Conclusion: Intoxications were more frequent in young female patients and drugs were the most common cause with suicidal intent. Unfortunately, CO poisoning continues to be a very important problem in our city. These findings provided significant information about the characteristics of intoxications in Karabuk.

流动性社会与高质量发展对中国地理学的理论创新提出了新的要求。在积极响应中国式现代化转型中的规划与治理需求过程中,中国地理学迫切需要对中国城乡社会的微观过程与行为机理进行刻画与解释,构建具有中国特色、指导中国社会建设的行为地理学研究范式。本文在借鉴西方地理学从计量革命走向行为革命的范式转型路径的基础上,提出中国地理学行为革命的理论框架,并讨论了行为革命对中国社会经济发展现实需求的意义和对中国地理学学科建设的贡献。行为革命立足于建立基于人的地理学解释框架,关注“时空间中的人”这一主体,构建以时空间行为交互与整合为核心的研究新范式,从个体行为与行为交互两个维度探索行为过程的机理解释,并引入新技术、新方法建立多维整合的混合研究路径,最终建立人地互动的决策支持系统。

Chalcogen heteroatoms doped nickel-nitrogen-carbon single-atom catalysts with asymmetric coordination for efficient electrochemical CO_(2)reduction

Chinese Journal of Catalysis 2024年第9期64卷 54-65页

The electronic configuration of central metal atoms in single-atom catalysts(SACs)is pivotal in electrochemical CO_(2)reduction reaction(eCO_(2)rr).Herein,chalcogen heteroatoms(e.g.,S,Se,and Te)were incorporated into the symmetric nickel-nitrogen-carbon(Ni-N4-C)configuration to obtain Ni-X-N3-C(X:S,Se,and Te)SACs with asymmetric coordination presented for central Ni *** these obtained Ni-X-N3-C(X:S,Se,and Te)SACs,Ni-Se-N3-C exhibited superior eCO_(2)rr activity,with CO selectivity reaching~98%at-0.70 V versus reversible hydrogen electrode(rHE).The Zn-CO_(2)battery integrated with Ni-Se-N3-C as cathode and Zn foil as anode achieved a peak power density of 1.82 mW cm-2 and maintained remarkable rechargeable stability over 20 ***-situ spectral investigations and theoretical calculations demonstrated that the chalcogen heteroatoms doped into the Ni-N4-C configuration would break coordination symmetry and trigger charge redistribution,and then regulate the intermediate behaviors and thermodynamic reaction pathways for eCO_(2)***,for Ni-Se-N3-C,the introduced Se atoms could significantly raise the d-band center of central Ni atoms and thus remarkably lower the energy barrier for the rate-determining step of*COOH formation,contributing to the promising eCO_(2)rr performance for high selectivity CO production by competing with hydrogen evolution reaction.
