OBJECTIVE

Traumatic brain injuries (TBIs) play a significant role in pediatric mortality and morbidity. Decompressive hemicraniectomy (DHC) is a treatment option for severe pediatric TBI (pTBI) not amenable to medical management of intracranial pressure. Posttraumatic hydrocephalus (PTH) is a known sequela of DHC that may lead to further injury and decreased capacity for recovery if not identified and treated. The goal of this study was to characterize risk factors for PTH after DHC in patients with pTBI by using the Kids’ Inpatient Database (KID).

METHODS

The records collected in the KID from 2016 to 2019 were queried for patients with TBI using International Classification of Diseases, 10th Revision codes. Data defining demographics, complications, procedures, and outcomes were extracted. Multivariate regression was used to identify risk factors associated with PTH. The authors also investigated length of stay and hospital charges.

RESULTS

Of 68,793 patients with pTBI, 848 (1.2%) patients underwent DHC. Prolonged mechanical ventilation (PMV) was required in 475 (56.0%) patients with pTBI undergoing DHC. Three hundred (35.4%) patients received an external ventricular drain (EVD) prior to DHC. PTH was seen in 105 (12.4%), and 50 (5.9%) received a ventriculoperitoneal shunt. DHC before hospital day 2 was negatively associated with PTH (OR 0.464, 95% CI 0.267–0.804; p = 0.006), whereas PMV (OR 2.204, 95% CI 1.344–3.615; p = 0.002) and EVD placement prior to DHC (OR 6.362, 95% CI 3.667–11.037; p < 0.001) were positively associated with PTH. PMV (OR 7.919, 95% CI 2.793–22.454; p < 0.001), TBI with subdural hematoma (OR 2.606, 95% CI 1.119–6.072; p = 0.026), and EVD placement prior to DHC (OR 4.575, 95% CI 2.253–9.291; p < 0.001) were independent predictors of ventriculoperitoneal shunt insertion. The mean length of stay and total hospital charges were significantly increased in patients with PMV and in those with PTH.

CONCLUSIONS

PMV, presence of subdural hematoma, and EVD placement prior to DHC are risk factors for PTH in patients with pTBI who underwent DHC. Higher healthcare resource utilization was seen in patients with PTH. Identifying risk factors for PTH may improve early diagnosis and efficient resource utilization.

North Russian prefix Z-: Between phonetics and morphemics
Authors: Nefedova Elena A.
Published: February 2023

The paper discusses the status of the formant z-, represented in the vocabulary of Arkhangelsk dialects of Russian. It mostly occurs on verbs, less often on words of other parts of speech. Consideration of its status concerns several aspects, such as phonetic position, semantics, correlation with synonymous prefixes, and area of usage. The formant z- in Arkhangelsk dialects is used both before obstruents and sonorants and /v-vʲ/. In the process of functioning, it moves from phonetics to morphemics, expanding the range of its meanings and, as a result, acquiring the capability to be used analogically to the prefixes vz-, za-, iz-, s-. The correlation between the semantics of z- and vz- is explained by the phonetic simplifi cation of [vz] before a consonant, whereby the resulting z- inherits all the meanings of vz-. In turn, the prefixes vz-, iz-, za-, s- show semantic commonalities, and this explains the possibility of formations with z- synonymous not only to formations with vz-, but also with iz-, za-, s- in the following meanings: ‘committing an action, bringing an action to the desired limit, result’ — a meaning common with the prefixes vz-, iz-, za-, s-; ‘upward direction of an action or movement’ — a meaning common with the prefixes vz-, za-; ‘starting an action’ — a meaning common with the prefixes vz-, za-; ‘performing a single action’ — a meaning common with the prefix vz-. Thus, the formant z- receives the status of a prefix, synonymous in all meanings to the prefix vz- and partly synonymous to the prefixes iz-, za-, s-. The conclusions about the genesis of the prefix z-, based on the analysis of the material of the Arkhangelsk dialects, are confirmed by the data of dictionaries of other Russian dialects, including those that are not in direct contact with the Belarusian and Ukrainian languages. The results of the study correlate with the problem of the general arealogy of Slavic dialects, aimed at revealing the relations between different languages, which represent their comparability.
PENEGAK HUKUM SEBAGAI GARDA TERDEPAN PERWUJUDAN NEGARA HUKUM DI INDONESIA
Authors: Wigiyanto Eko
Published: February 2023

Indonesia is a state of law that always puts the law as a reference in all activities of the state and society. Indonesia's commitment to become a state of law is clearly stated in the 1945 Constitution "Indonesia is a state of law". As a state of law, judicial institutions have been established in charge of maintaining and supervising the application of law so that it can be effective in Indonesia. The judiciary is also present as a form of media for the public to obtain justice and appropriate action in the eyes of the law. As a citizen, it is the duty to be positive in the process of protecting and enforcing the law in Indonesia. The state wants a judicial institution in which it has law enforcement officers and law enforcement agencies that are fair and firm, indiscriminately. There is no sabotage, discrimination and specialization in handling every legal case, whether criminal or civil. However, nowadays we often hear the phrase, 'Point to the bottom Blunt to the top'. This expression can be present because it is considered to reflect the state of law enforcement in Indonesia. The author's search results show that the state of law enforcement in Indonesia is not running as expected. Law enforcement by the judiciary in Indonesia is often tainted by entrenched judicial corruption. Various legal cases that are currently happening seem to prove that this expression is true. The focus of this article is related to how law enforcement is currently in Indonesia. The question in this article is whether law enforcement has become the front line in the realization of the rule of law in Indonesia

Authors: Hou Zhuo
Published: February 2023

The epidemic situation in COVID-19 aggravated the pressure and challenges of enterprises ‘management, which directly affected employees’ working attitudes. This paper takes organizational career planning management as the independent variable and takes job satisfaction, turnover intention, and organizational commitment as the proxy variables of dependent variables. H Company is taken as the research object, with 17 qualitative interviews and 645 cluster sampling surveys. Through correlation and regression analysis, the conclusions can be drawn: 1. The implementation of career planning management has a significant impact on employees’ work attitude, a positive impact on job satisfaction and organizational commitment, and a negative impact on turnover intention. 2. Each dimension of career planning management has a different action mechanism on each proxy variable of employees’ work attitudes. Fair promotion, providing information, and paying attention to training and career development in career planning management can significantly promote job satisfaction and job commitment. However, paying attention to training and career development significantly inhibits turnover intention, while the other two dimensions have no significant influence. Based on these conclusions, the enterprises can promote employees’ job satisfaction and organizational commitment by enhancing their career planning management awareness, establishing a perfect career planning management system, and carrying out diversified career planning management practices.

Published: February 2023

The construction of a national education credit bank (ECBS) and the “1+X” certification (XCERT) are both key ways to build a modern vocational education system in China. The XCERT has laid the practical foundation for the construction of ECBS. The ECBS has created an excellent institutional environment for implementing the XCERT . Therefore, from the perspective of the ECBS, the current situation of digital talent cultivation and the implementation cases of the XCERT are sorted out. Using the case study method, we analyzed the problems of lack of cooperation among organizations, lack of professional digital talent training and evaluation system, and lack of experience in organizing vocational skills certificate examinations in the implementation process of XCERT. In response to these problems, countermeasures for the construction of the XCERT are proposed, for example, strengthening the cooperation mechanism among organizations, improving the digital talent education model, improving the quantity and quality of education and evaluation organizations, optimizing the digital talent education program, and improving the application-oriented curriculum system.

Authors: Huang Yue , Gao Peng , Yang Zhenlin
Published: February 2023

The remote sensor mounted on the Fengyun-3C (FY-3C) will decay naturally during the operation, causing a decrease in the accuracy of the satellite data. Therefore, an effective monitoring method must be adopted to study the performance changes of the instrument. The theoretical expressions of the absolute and relative errors for the earth field of view (FOV) radiance together with its equivalent brightness temperature are given by analyzing the response value offsets of the earth FOV along with the blackbody (BB) pixel. In order to further describe the influences of different parameters on the absolute and relative errors for the FOV radiance and equivalent brightness temperature, the computer simulations are performed, and the absolute errors for the FOV radiance and equivalent brightness temperature caused the response value offset of the BB pixel firstly decrease and then increase with the increasing of the earth FOV response value. The absolute and relative errors for the FOV radiance caused the response value offset of the earth FOV firstly decrease and then increase, and the absolute error for the equivalent brightness temperature increases while its relative error decreases with the increasing of the response value of the earth FOV. This research provides an important theoretical guidance for improving the on-orbit performance of the FY-3C/ MERSI.

Published: February 2023

Sensitivity analysis about small watershed is an important way to objectively understand the development characteristics of debris flow ditches. With the support of Remote Sensing and Geographic Information System technologies, Dongchuan County with frequent debris flow development in Kunming, Yunnan Province, southwest China was selected as the research object, the Landsat image and Digital Elevation Model were used to interpret the small watersheds on both sides of the Xiaojiang River. By selecting four indicators of fault zone, slope, gully density and land use as the impact factors, the sensitivity coefficients were quantitatively calculated. The following research results were obtained: The distribution feature of debris flow small watersheds was that, the Dongchuan fault zone was the axis which small watersheds were symmetrically distributed on; the sensitivity of the Dongchuan fault zone was the highest in the buffer distance of 5-10 km, which was prone to debris flow disasters; the debris flow was most sensitive in the slope range of 40°-50°; the debris flow was most sensitive to the gully density of 0.6-0.9 km/km2 with broken surface; three types of land use such as bare land, water and construction land had high sensitivity coefficient and were easy to cause mountain disasters. According to the sensitivity coefficients of the above impact factors, the stacking method superposition analysis was carried out to obtain the sensitivity distribution of debris flow disasters in Dongchuan County. The medium sensitive area accounted for 53.84% of the total area, and the high sensitive area accounted for 27.02% of the total area. The medium sensitive area and the high sensitive area were the main areas where debris flow occurred. This study has certain reference significance for disaster prevention, soil and water conservation by quantitative calculation and comparison of debris flow disaster sensitivity.

This paper presents the modeling of the inverse kinematic problem related to the motions of a delta planar robot using the algebra of unitary Quaternions. The mathematical model resulting from the inverse kinematic analysis has an associated system of 8 nonlinear algebraic equations with 8 polynomial unknowns. The Newton-Raphson method was used to solve the mathematical model of the robot. Subsequently, using the inverse model of the robot, a database was constructed that relates the Cartesian coordinates of the end effector to the angles and axes of the rotations of the links. This database was used to train a multilayer neural network in order to have an equivalent model of the inverse problem. A series of experiments were performed to obtain an improved network configuration by varying four training parameters. The results obtained show that the improved trained network can be used to solve the inverse problem of the studied robot.

Methods: The development of this protocol follows a mixed-methodology approach, consisting of three stages: 1) development of the protocol of the intervention, 2) a randomized controlled trial study with two arms over six months that includes an intervention group and a control group, and 3) the evaluation of the protocol by trainers. In the second stage, we recruited a total of 128 people with MCI from the five participating countries of this study (Greece, Spain, Croatia, Slovenia, and Italy). This educational program will assess three main outcomes after 6 months of the English Lessons with the Use of Songs for People with Mild Cognitive Impairment (E.L.So.M.C.I.) workshops. Results: Our primary outcome will hopefully be an improvement in general cognition in the intervention group compared to the control group from baseline to 6 months follow-up. Secondary outcomes include a decrease in participants’ anxiety and depression and an improvement in their quality of life. Development of English language skills is the last outcome.

Background: Growing evidence show that long term exposure to air pollution increases the risk of dementia. Objective: The aim of this study was to investigate associations between PM2.5 exposure and dementia in a low exposure area, and to investigate the role of olfaction and the APOE ɛ4 allele in these associations. Methods: Data were drawn from the Betula project, a longitudinal study on aging, memory, and dementia in Sweden. Odor identification ability was assessed using the Scandinavian Odor Identification Test (SOIT). Annual mean PM2.5 concentrations were obtained from a dispersion-model and matched at the participants’ residential address. Proportional hazard regression was used to calculate hazard ratios. Results: Of 1,846 participants, 348 developed dementia during the 21-year follow-up period. The average annual mean PM2.5 exposure at baseline was 6.77μg/m3, which is 1.77μg/m3 above the WHO definition of clean air. In a fully adjusted model (adjusted for age, sex, APOE, SOIT, cardiovascular diseases and risk factors, and education) each 1μg/m3 difference in annual mean PM2.5-concentration was associated with a hazard ratio of 1.23 for dementia (95% CI: 1.01–1.50). Analyses stratified by APOE status (ɛ4 carriers versus non-carriers), and odor identification ability (high versus low), showed associations only for ɛ4 carriers, and for low performance on odor identification ability. Conclusion: PM2.5 was associated with an increased risk of dementia in this low pollution setting. The associations between PM2.5 and dementia seemed stronger in APOE carriers and those with below average odor identification ability.

Background: Cognitive reserve (CR) is hypothesized to partially explain the discrepancy between Alzheimer’s disease related brain pathology and cognitive performance. Educational attainment is often used as a proxy for CR. Objective: To examine the association of years of education and the relationship between atrophy in the medial temporal lobe and episodic memory, in a cross-sectional ecological multi-center memory clinic cohort. Methods: Included patients (n = 702) had undergone memory clinic examination and were diagnosed with subjective cognitive impairment (n = 99), mild cognitive impairment (n = 471), or dementia (n = 132). Total years of education were used as a moderating variable and neuropathology was operationalized as visual ratings of medial temporal lobe atrophy (MTA) on magnetic resonance imaging and computer tomography images. Weighted least squares regression and multiple regression were used to analyze moderation and the effect of education separately by diagnostic group. A composite score of two episodic memory tests constituted the dependent variable. Results: After controlling for age and gender the interaction term between MTA and years of education was significant indicating moderation. In particular, the regression model showed that at low levels of MTA, high education individuals had better episodic memory performance. However, at higher MTA levels, high education individuals had the lowest episodic memory performance. Education had a significant positive effect on episodic memory in SCI and MCI, but not dementia. Conclusion: These results extend the findings of education moderating the effect of MTA on cognition to a naturalistic memory clinic setting. Implications of the findings for theories on CR are discussed.

Background: Apolipoprotein E (APOE) is closely related to Alzheimer’s disease and other age-related diseases. In recent years, several studies have shown an interaction of APOE by age on brain volume. However, validation in larger cohorts is required. Objective: We explored the age-related effect of APOE on brain volumes in a community-dwelling cohort. Methods: Inhabitants in Shunyi District in Beijing aged≥35 years were invited to join this study from 2013 to 2016. The baseline assessments, APOE genotyping and brain magnetic resonance imaging were performed. Neuroimaging small vessel disease characteristics and brain volumes (global measures, cerebral lobes, hippocampus, brainstem, and subcortical nuclei) were acquired. The general linear model was used to analyze the interaction of APOE genotypes by age on brain volumes, and the age of 60 years was chosen as a cut-off value for stratification analysis. Results: A total of 1,105 subjects were enrolled in the final analysis with a mean age of 56.18 (9.30) years, and 37.7% were men. APOE ɛ3/ɛ3 carriers account for 71.8%, ɛ2 (+) 14.0%, and ɛ4 (+) 14.2%. Compared with APOE ɛ3/ɛ3, a significant protective effect for APOE ɛ4 (+) on brain parenchyma fraction (β  =  0.450, p = 0.048) was observed in subjects aged≤60 years; in participants aged > 60 years, a negative effect for APOE ɛ4 (+) on hippocampus (β  =  1.087, p = 0.021) was found. Conclusion: Our study reveals that APOE ɛ4 has differential effects on cerebral structures in different stages of lifespan, suggesting its complicated biological function and underlying antagonistic pleiotropy.
The Generalizability of Longitudinal Changes in Speech Before Alzheimer’s Disease Diagnosis

Published: February 2023

Background: Language impairment in Alzheimer’s disease (AD) has been widely studied but due to limited data availability, relatively few studies have focused on the longitudinal change in language in the individuals who later develop AD. Significant differences in speech have previously been found by comparing the press conference transcripts of President Bush and President Reagan, who was later diagnosed with AD. Objective: In the current study, we explored whether the patterns previously established in the single AD-healthy control (HC) participant pair apply to a larger group of individuals who later receive AD diagnosis. Methods: We replicated previous methods on two larger corpora of longitudinal spontaneous speech samples of public figures, consisting of 10 and 9 AD-HC participant pairs. As we failed to find generalizable patterns of language change using previous methodology, we proposed alternative methods for data analysis, investigating the benefits of using different language features and their change with age, and compiling the single features into aggregate scores. Results: The single features that showed the strongest results were moving average type:token ratio (MATTR) and pronoun-related features. The aggregate scores performed better than the single features, with lexical diversity capturing a similar change in two-thirds of the participants. Conclusion: Capturing universal patterns of language change prior to AD can be challenging, but the decline in lexical diversity and changes in MATTR and pronoun-related features act as promising measures that reflect the cognitive changes in many participants.

Background: Mild cognitive impairment (MCI) is the prodromal stage of dementia. In this stage, reasonable intervention measures can help to delay the decline of cognitive function. Supplementation of n-3 polyunsaturated fatty acids (n-3PUFAs) may be beneficial to delay the decline of cognitive function in the elderly. Objective: To investigate the effectiveness of docosapentaenoic acid (DHA) or/and eicosapentaenoic acid (EPA) supplements in the elderly with MCI. Methods: Eight electronic databases, PubMed, Cochrane Library, Embase, VIP, SinoMed, Web of Science, CNKI, and WANFANG DATA, were searched for related articles from inception until January 2022. Subgroup analyses and sensitivity analyses were performed to detect confounding variables. Standardized mean differences (SMD) with 95% confidence intervals (CI) were determined. Heterogeneity was evaluated by I2 statistics. Publication bias was detected using funnel plots. Stata12.0 was used for Begg’s and Egger’s test to quantify whether publication bias. Linear relationship between global cognition and covariates was examined in meta-regression analysis. Results: Twelve studies (n = 1,124) were included. The methodological quality of research is mostly medium. Compared with placebo, n-3PUFAs supplements have benefits on global cognition [SMD = 0.51, 95% CI(0.12, 0.91), p = 0.01]. No significant differences were observed between intervention group and placebo on language fluency, executive functions, and depression. Conclusion: Our findings indicated DHA and/or EPA supplements have benefits on global cognition, and it may also reduce the level of blood amyloid-β (Aβ)-related biomarkers (e.g., Aβ40, Aβ42) and inflammatory factors (e.g., 1L-6, 1L-10). Since there are only two relative articles, more research is needed in the future to clarify the relationship.
