Construction and Application of a Model for Predicting the Risk of Delirium in Postoperative Patients With Type a Aortic Dissection
Authors: He Junfeng , Ling Qing , Chen Yuhong 
Published: November 2021

Background: Postoperative delirium (POD), an alteration in a patient's consciousness pattern, can affect the treatment and prognosis of a disease.Objective: To construct a prediction model for delirium in patients with type A aortic dissection after surgery and to validate its effectiveness.Methods: A retrospective cohort design was used to study 438 patients undergoing surgical treatment for type A aortic dissection from April 2019 to June 2020 in tertiary care hospitals. POD (n = 78) and non-delirium groups (n = 360) were compared and analyzed for each index in the perioperative period. A prediction model was established using multifactorial logistic regression, and 30 patients' perioperative data were collected for model validation.Results: Eight predictors were included in this study: smoking, diabetes, previous cardiovascular surgery, ejection fraction (EF), time to aortic block, acute kidney injury, low cardiac output syndrome, and pulmonary complications. The area under the receiver operating characteristic (ROC) curve of the constructed prediction model was 0.98 ± 0.005, and the Youden index was 0.91. The validation results showed 97% sensitivity, 100% specificity, and 93% accuracy. The expression of the model was Z = Smoking assignment* – 2.807 – 6.009*Diabetes assignment – 2.994*Previous cardiovascular surgery assignment – 0.129*Ejection fraction assignment + 0.071*Brain perfusion time assignment – 2.583*Acute kidney injury assignment – 2.916*Low cardiac output syndrome assignment – 3.461*Pulmonary related complications assignment + 20.576.Conclusion: The construction of an effective prediction model for the risk of delirium in patients after type A aortic stratification can help identify patients at high risk of POD early. It also provides a reference for healthcare professionals in the prevention and care of these patients.

Objectives: The COVID-19 pandemic represents a major crisis for governments and populations. The public’s risk perceptions, knowledge, and behaviors are key factors that play a vital role in the transmission of infectious diseases. Our scoping review aims to map the early evidence on risk perceptions, knowledge, and behaviors of general and high-risk adult populations towards COVID-19.Methods: A systematic scoping review was conducted of peer-reviewed articles in five databases on studies conducted during the early stages of COVID-19. Thirty-one studies meeting the inclusion criteria were appraised and analyzed.Results: The levels of risk perceptions, knowledge, and behaviors towards COVID-19 were moderate to high in both general and high-risk adult populations. Adults were knowledgeable about preventive behaviors. Our review identified hand-washing and avoiding crowded places as dominant preventive behaviors. Being a female, older, more educated, and living in urban areas was associated with better knowledge of COVID-19 and appropriate preventive behaviors.Conclusion: This review offers a first understanding of risk perceptions, knowledge and behaviors of adult populations during the early stages of the COVID-19 pandemic.
Implicit Associations between Adverbs of Place and Actions in the Physical and Digital Space
Authors: Craighero Laila , Marini Maddalena 
Published: November 2021

Neuropsychological, behavioral, and neurophysiological evidence indicates that the coding of space as near and far depends on the involvement of different neuronal circuits. These circuits are recruited on the basis of functional parameters, not of metrical ones, reflecting a general distinction of human behavior, which alternatively attributes to the individual the role of agent or observer. Although much research in cognitive psychology was devoted to demonstrating that language and concepts are rooted in the sensorimotor system, no study has investigated the presence of implicit associations between different adverbs of place (far vs. near) and actions with different functional characteristics. Using a series of Implicit Association Test (IAT) experiments, we tested this possibility for both actions performed in physical space (grasp vs. look at) and those performed when using digital technology (content generation vs. content consumption). For both the physical and digital environments, the results showed an association between the adverb near and actions related to the role of agent, and between the adverb far and actions related to the role of observer. Present findings are the first experimental evidence of an implicit association between different adverbs of place and different actions and of the fact that adverbs of place also apply to the digital environment.
Zn2+-Dependent Nuclease Is Involved in Nuclear Degradation during the Programmed Cell Death of Secretory Cavity Formation in Citrus grandis ‘Tomentosa’ Fruits
Authors: Liang Minjian , Bai Mei , Wu Hong 
Published: November 2021

Zn2+- and Ca2+-dependent nucleases exhibit activity toward dsDNA in the four classes of cation-dependent nucleases in plants. Programmed cell death (PCD) is involved in the degradation of cells during schizolysigenous secretory cavity formation in Citrus fruits. Recently, the Ca2+-dependent DNase CgCAN was proven to play a key role in nuclear DNA degradation during the PCD of secretory cavity formation in Citrus grandis ‘Tomentosa’ fruits. However, whether Zn2+-dependent nuclease plays a role in the PCD of secretory cells remains poorly understood. Here, we identified a Zn2+-dependent nuclease gene, CgENDO1, from Citrus grandis ‘Tomentosa’, the function of which was studied using Zn2+ ions cytochemical localization, DNase activity assays, in situ hybridization, and protein immunolocalization. The full-length cDNA of CgENDO1 contains an open reading frame of 906 bp that encodes a protein 301 amino acids in length with a S1/P1-like functional domain. CgENDO1 degrades linear double-stranded DNA at acidic and neutral pH. CgENDO1 is mainly expressed in the late stage of nuclear degradation of secretory cells. Further spatiotemporal expression patterns of CgENDO1 showed that CgENDO1 is initially located on the endoplasmic reticulum and then moves into intracellular vesicles and nuclei. During the late stage of nuclear degradation, it was concentrated in the area of nuclear degradation involved in nuclear DNA degradation. Our results suggest that the Zn2+-dependent nuclease CgENDO1 plays a direct role in the late degradation stage of the nuclear DNA in the PCD of secretory cavity cells of Citrus grandis ‘Tomentosa’ fruits.

РЕАЛІЗАЦІЯ АВТОРСЬКОЇ ПЕДАГОГІЧНОЇ СИСТЕМИ В. СУХОМЛИНСЬКОГО В ОСВІТНЬОМУ ПРОЦЕСІ ПРИРОДНОГО СЕРЕДОВИЩА ЗАКАРПАТТЯ

Анотація. У статті представлено дослідження авторської педагогічної системи Василя Сухомлинського, охарактеризовано форми освітньої діяльності «під блакитним небом». Окреслено фактори удосконалення професіоналізму вчителя, які, на переконання В. Сухомлинського, розкривають творчий потенціал вчителя і визначають сенс його професіоналізму впродовж життя: наявність у нього віри в дитину; поєднання емоційної культури з тактом; дотримання вчителем інтелектуальної культури; орієнтація учнів на особистий приклад вчителя; поглиблення, поповнення, удосконалення знань; самоаналіз педагогічної праці; її дослідницький, творчий характер, використання передового педагогічного досвіду; атмосфера багатого духовного життя колективу.
Великий педагог довів, що природа сама собою не виховує, виховує лише активна взаємодія дитини з нею. Тому екологічне виховання та екологічна культура тісно пов’язані з природоохоронною діяльністю. В.Сухомлинський вважав, що самих екологічних знань з охорони навколишнього середовища, якщо вони не втілюються на практиці, недостатньо. Важливо, щоб вихованці брали участь у збереженні і збагаченні природи рідного краю, тільки у цьому разі у них формуються необхідні уміння і навички, розвивається відповідальне, бережне ставлення до навколишнього середовища.
