Sleep Biomarkers for Predicting Cognitive Decline and Alzheimer’s Disease: A Systematic Review of Longitudinal Studies
Authors: Carpi Matteo , Fernandes Mariana , Mercuri Nicola Biagio , Liguori Claudio
Published: December 2023

Background: Sleep disturbances are considered a hallmark of dementia, and strong evidence supports the association between alterations in sleep parameters and cognitive decline in patients with mild cognitive impairment and Alzheimer’s disease (AD). Objective: This systematic review aims to summarize the existing evidence on the longitudinal association between sleep parameters and cognitive decline, with the goal of identifying potential sleep biomarkers of AD-related neurodegeneration. Methods: Literature search was conducted in PubMed, Web of Science, and Scopus databases from inception to 28 March 2023. Longitudinal studies investigating the association between baseline objectively-measured sleep parameters and cognitive decline were assessed for eligibility. Results: Seventeen studies were included in the qualitative synthesis. Sleep fragmentation, reduced sleep efficiency, reduced REM sleep, increased light sleep, and sleep-disordered breathing were identified as predictors of cognitive decline. Sleep duration exhibited a U-shaped relation with subsequent neurodegeneration. Additionally, several sleep microstructural parameters were associated with cognitive decline, although inconsistencies were observed across studies. Conclusions: These findings suggest that sleep alterations hold promise as early biomarker of cognitive decline, but the current evidence is limited due to substantial methodological heterogeneity among studies. Further research is necessary to identify the most reliable sleep parameters for predicting cognitive impairment and AD, and to investigate interventions targeting sleep that can assist clinicians in the early recognition and treatment of cognitive decline. Standardized procedures for longitudinal studies evaluating sleep and cognition should be developed and the use of continuous sleep monitoring techniques, such as actigraphy or EEG headband, might be encouraged.
Real-time identification of small anomalies from scattering matrix without background information
Authors: Park Won-Kwang
Published: December 2023

Several researches have confirmed the possibility of localizing small anomalies via Kirchhoff migration (KM); however, when the background information is unknown, small anomalies cannot be satisfactorily retrieved. This fact can be examined through the simulation results; however, related theoretical result to explain the reason of such phenomenon has not yet been investigated. In this contribution, we show that the imaging function of the KM can be expressed by an infinite series of the Bessel function of the first kind, material properties, and antenna arrangement, and applied alternative value of the background wavenumber. Based on the theoretical result, we explain why the exact location and shape of anomalies cannot be retrieved. The simulation results with synthetic data exhibited to support the theoretical result.

Published: December 2023

This paper introduces Buckingham’s 𝜋 theorem in the context of Non-Destructive Testing & Evaluation (NDT&E). Its application leads to easier problems to handle by reducing the number of variables involved. In this sense, dimensional analysis can provide the foundation for in-line, real-time and low-cost inspection methods that are fully compatible with the requirements of the Industry 4.0 and NDE 4.0 paradigms. In order to show the impact of the Buckingham’s 𝜋 theorem in NDT&E, we consider a practical case of interest, i.e. the simultaneous estimation of thickness and electrical conductivity of metallic plates via Eddy Current Testing. An initial numerical analysis is carried out with the aim to show the metrological performance of the method. The results obtained show that the method combines good accuracy with low computational costs.

Authors: Bouali Ferroudja , Mohellebi Hassane
Published: December 2023

The present work concerns the study of the effect of variation of the thickness of 2D cylindrical test-piece and lift-off (the air gap between the sensor and the test-piece) on the sensor response in case of transient source current. The coupled circuit’s method employed is based on the mutual’s inductances calculation and with the association to Kirchhoff laws it yields to a transient algebraic equations system which is solved at each time step. The method is applied to the study of the pulsed eddy currents in cylindrical and axisymmetric device with electrical conductivity and geometrical dimensions variations.

Authors: Ajileye A.B. , Akinbo F.O.
Published: December 2023

BACKGROUND:

The thousands of chemicals and compounds found in cigarette smoke, including many free radicals and oxidants, can cause oxidative damage to DNA either directly or by producing reactive oxygen species in cultured cells. This study was carried out to analyze the urinary 8-Oxoguanine DNA Glycosylase (OGG1) and 8-Hydroxy-2’ –Deoxyguanosine (8-OHdG) among cigarette and non-cigarette smokers in South-West, Nigeria.

METHODS:

Urine samples were collected from 250 cigarette smokers and 200 non-cigarette smokers who live in south-west, Nigeria. Questionnaire was administered first to both cigarette and non-cigarette smokers prior to specimen collection. About 10mls of urine samples were collected from each of the subjects and was used to carry out Oxoguanine Glycosylase and 8-Hydroxyl-2-deoxyguanosine using spectrophotometer at 450 nm wavelength.

RESULTS:

There was a significant ( P < 0.05) increase in Urinary 8-OHdG (345.84±90.98 vs 223±68.48) and OGG1 (220.71±59.55 vs 97.20±56.14) of the cigarette smokers when compared with that of non-cigarette smokers.

CONCLUSION:

On the basis of this study, it has been observed and established that indulging in cigarette smoking can result in oxidative stress and DNA damage.
Improving Open Government Data Performance of Local Governments: A Configurational Analysis Based on TOE Framework
Authors: Mo Fuchuan , Zhang Xiaojuan , Feng Cuicui
Published: December 2023

Open Government Data (OGD) is leading the way towards digitization, intelligence, and transparency of public services and government decision-making. Aiming at elucidating the configurational path of OGD performance of local governments, this paper employs the technology-organization-environment (TOE) framework and the fuzzy set qualitative comparative analysis (fsQCA) to explore the key factors and configuration paths of OGD performance from the cases of 31 provincial OGD practice in China. Results indicate that OGD performance depends on the combination of technical, organizational, and external environment conditions, and that there exist substitution relationships among the various preconditions for the improvement of OGD performance, including information infrastructure, technology application capability, data resources, economic strength, policy regulations, and inter-government competition, as discussed in previous TOE based research. Specifically, seven configuration paths are identified to achieve high-level OGD performance, namely, Technology-Organization-Environment combined driven, Economy-Talent-Demand driven, Institution-Data-Policies driven, Institution-Economy-Demand driven, Organization-Policies-Competition driven, Data-Economy-Demand driven, and Data-Policies-Competition driven. This research is of particular significance to achieve high-level OGD performance for local governments with different resources and environments.
A new integrated remanufacturing process planning and scheduling model under uncertainties using extended non-dominated sorting genetic algorithm-II
Authors: Xu Huifen , Fang Cheng , Zhang Shuai
Published: December 2023

Remanufacturing, with its environmental and economic implications, is gaining significant traction in the contemporary industry. Owing to the complementarity between remanufacturing process planning and scheduling in actual remanufacturing systems, the integrated remanufacturing process planning and scheduling (IRPPS) model provides researchers and practitioners with a favorable direction to improve the performance of remanufacturing systems. However, a comprehensive exploration of the IRPPS model under uncertainties has remained scant, largely attributable to the high complexity stemming from the intrinsic uncertainties of the remanufacturing environment. To address the above challenge, this study proposes a new IRPPS model that operates under such uncertainties. Specifically, the proposed model utilizes interval numbers to represent the uncertainty of processing time and develops a process planning approach that integrates various failure modes to effectively address the uncertain quality of defective parts during the remanufacturing process. To facilitate the resolution of the proposed model, this study proposes an extended non-dominated sorting genetic algorithm-II with a new multi-dimensional representation scheme, in which, a new self-adaptive strategy, multiple genetic operators, and a new local search strategy are integrated to improve the algorithmic performance. The simulation experiments results demonstrate the superiority of the proposed algorithm over three other baseline multi-objective evolutionary algorithms.

Time-sensitive programs that are linked to smart services, such as smart healthcare as well as smart cities, are supported in large part by the fog computing domain. Due to the increased speed limitation of the cloud, Cloud Computing (CC) is a competent platform for fog in data processing, but it is unable to meet the demands of time-sensitive programs. The procedure of resource provisioning, as well as allocation in either a fog-cloud structure, takes into account dynamic changes in user requirements, and resources with limited access in fog devices are more difficult to manage. Due to the continual changes in user requirement factors, the deadline represents the biggest obstacle in the fog computing structure. Hence the objective is to minimize the total cost involved in scheduling by maximizing resource utilization. For dynamic scheduling in the fog-cloud computing model, the efficiency of hybridization of the Grey Wolf Optimizer (GWO) and Lion Algorithm (LA) is developed in this study. In terms of energy costs, processing costs, and communication costs, the created GWOMLA-based Deep Belief Network (DBN) performed better and outruns the other traditional models.
Lagrange-enhanced GRA framework for probabilistic simplified neutrosophic multiple-attributes decision-making and applications to painting teaching quality evaluation
Authors: Xu Dongsheng
Published: December 2023

Universities are important talent training bases in China and the main driving force for achieving the strategic layout of “revitalizing the country through science and education” and “strengthening the country through talent". Oil painting is a global art with rich humanistic and artistic value. Most art colleges in China have set up oil painting courses. Analyze the current situation and value of oil painting course teaching in local art (teacher training) majors, and leverage the educational role of oil painting courses by enriching course offerings, emphasizing the integration of humanistic innovation, improving teacher literacy, and striving to further improve the quality and efficiency of oil painting course teaching. The quality evaluation of oil painting teaching in universities is viewed as multiple-attribute decision-making (MADM). The grey relational analysis (GRA) is a useful tool to cope with the MADM issue. The probabilistic simplified Neutrosophic set (PSNSs) is easy to characterize uncertain information during the quality evaluation of oil painting teaching in universities. In this paper, in order to obtain the weight information, an optimization model implemented to obtain a simple and exact formula which can be employed to derive the attribute weights values based on the Lagrange function and the probabilistic simplified neutrosophic number grey relational analysis (PSNN-GRA) technique is implemented for MADM to rank the alternatives. Finally, a numerical example for quality evaluation of oil painting teaching in universities is used to verify the practicability of the PSNN-GRA technique and compares it with other techniques.
Prognostic dilemmas for SIDS in idiopathic fetal right atrium dilatation: Case report and review literature
Authors: Stabile M. , Cipullo L.M.A. , Carlucci S. , Rispoli A.F. , Stabile G.
Published: December 2023

The authors describe a case of fetal isolated right atrial enlargement or IDRA (idiopathic dilatations of the right atrium) evident in third trimester, complicated by arrhythmia in the female infant during the 1° month of life with ECG diagnosis of Wolf-Parkinson-White syndrome (WPW). The eldest sister died at 6 years because of an arrhythmia with the same diagnosis of WPW. The review of the literature on IDRA frequently shows a familial genetic aggregation. The pathogenetic mechanism underlying the dilation of the right atrium could consist of a myopathy or electrical conduction disorder. The exclusive involvement of the right atrium may be due to the increased pressure in the fetal right atrium. On the basis of our case and after review of the literature, we must be careful in defining as physiological the enlargement of the right fetal atrium in the third trimester of pregnancy. The ultrasound sign of IDRA may be a fetal prodrome of SIDS (sudden infant death syndrome).

Authors: Simon R. , Shay R. , Bergam B. , Katz R. , Delaney S.
Published: December 2023

BACKGROUND:

Bowel dilation and bowel wall thickness are common prenatal ultrasound measurements for fetuses with gastroschisis. Data regarding antenatal sonographic bowel findings and postnatal outcomes are conflicting. Our objective was to evaluate the impact of in utero bowel measurements on perinatal outcomes in gastroschisis pregnancies.

METHODS:

Retrospective cohort study of 116 pregnancies complicated by gastroschisis between 2011 and 2020. We reviewed ultrasounds documenting fetal bowel measurements. To evaluate the association of these measurements with antepartum and delivery outcomes, we ran logistic and linear models using generalized estimating equations.

RESULTS:

Eleven perinatal outcomes reached statistical significance, although with minimal clinical impact given small magnitude of effect. Intra-abdominal bowel dilation was associated with a 0.5 week decrease in delivery gestational age (GA) (95% CI –0.07, –0.03) and a 6.93 g increase in birth weight (95% CI 1.54, 28.73). Intra-abdominal bowel wall thickness was associated with later GA of non-stress test (NST) start of 0.22 weeks (95% CI 0.07, 0.37), increased delivery GA of 0.08 weeks (95% CI 0.02, 0.15), 0.006 decrease in umbilical artery (UA) pH (95% CI –0.009, –0.003), 0.26 increase in UA base deficit (95% CI 0.09, 0.43), and decreased odds of cesarean delivery (OR = 0.83, 95% CI 0.70, 0.99). Extra-abdominal bowel wall thickness was associated with a 0.1 increase in UA base deficit (95% CI 0.02, 0.19) and a 0.05 increase in 5-min APGAR score (95% CI 0.01, 0.09). Stomach cross-section was associated with a 0.01 week decrease in delivery GA (95% CI –0.02, –0.001) and increased odds of receiving betamethasone (OR = 1.02, 95% CI 1.01, 1.04).

CONCLUSIONS:

In utero bowel characteristics reached statistical significance for several outcomes, but with minimal meaningful clinical differences in outcomes.

Authors: Sadeghzadeh Mansour , Khoshnevisasl Parisa , Fallah Ramezan , Marzban Asghar , Ghodrati Davood
Published: December 2023

BACKGROUND:

Intra ventricular hemorrhage (IVH) is a major cause of mortality among very low birth weight infants. This study aimed to investigate the relationship between mean platelet volume (MPV) and IVH in very low birth weight infants.

METHOD:

In this cohort study, all premature infants weighing less than 1500 grams who were admitted to the NICU were enrolled from August 2018 to July 2019. Brain ultrasonography was performed on the first and seventh days and one month of age and were compared with Platelet count and MPV.

RESULTS:

From 183 neonates, 23 cases (12.6%) had IVH. The mean MPV on the first day in the group with IVH was 10.48±0.85 and in the non-IVH group was 9.9±0.74 ( P = 0.005). The mean MPV on the seventh day in the IVH and non-IVH group were 10.4±0.92 and 10.03±0.74 ( P = 0.04) respectively. On the first and seventh day, for one unit of MPV increase, the chance of IVH increased by 2.68 and 2.1 respectively. ( p = 0.001; OR3.643; 95% CI [ 1.703 – 7.753 ]).

CONCLUSION:

The mean MPV index is significantly higher in the infants with IVH and therefore it can be used in early detection of IVH in neonates weighing less than 1500 grams.

Authors: Li Xiao-Xiao , Yu Hai-Yun , Li Jing-Jing , Liu Xiao-Long , Zheng Hang-Yu , Li Yan-Fei , Li Qi , Liu Si-Yuan
Published: December 2023

BACKGROUND: Visual vertigo (VV) is a disease characterized by various visual signal-induced discomforts, including dizziness, unsteady balance, activity avoiding, and so forth. Distinguishing it from other kinds of dizziness is important because it needs the combination of visual training and vestibular rehabilitation together. However, there is no appropriate tool to diagnose VV in China, thus we would like to introduce an effective tool to China. OBJECTIVE: The aim of this study was to establish the reliability and validity of the Chinese version of visual vertigo analogue scale (VVAS-CH) and to achieve its cross-cultural adaptation in order to promote its further usage in China. METHODS: A total of 1681 patients complaining of vertigo or dizziness were enrolled and they were asked to complete the VVAS-CH. The cross-cultural adaptation, reliability and construct validity of the VVAS-CH were determined. RESULTS: Split-half reliability was 0.939, showing a good reliability. Factor analysis identified only one common factor for the nine items that explained 64.83% of the total variance. Most fit indices reached acceptable levels, proving the good fit of the VVAS-CH model. CONCLUSIONS: The VVAS-CH validated in this study can be used as an effective tool for diagnosing and evaluating VV in patients whose native language is Chinese.

Authors: Fokides Emmanuel , Samioti Antigoni
Published: December 2023

Teaching concepts related to the natural environment in early childhood education significantly impacts cognitive development and corrects misconceptions. Technological advancements have introduced innovative educational tools such as virtual reality (VR). Among the various forms of VR, desktop VR (dVR) is the most practical for use in a school setting, as it requires no specialized equipment other than computers. With this in mind, a project was implemented to examine the impact of a dVR application on kindergarten students' learning. A total of forty-five students participated in a within-subjects research design, studying the seasons of the year. The learning outcomes were then compared with those produced by conventional materials. Furthermore, students' feelings and attitudes were also analyzed. The results showed that when using the dVR application, students performed significantly better in terms of learning, immersion, motivation, enjoyment, and ease of use. Factors such as students' gender and prior knowledge did not have any significant effect. The study's implications for research and education are also discussed.

Investigation of the Spatial Changes in Overbank Floodplains and Sedimentations on the Study Site of the Middle Tisza
Authors: Tóth Péter
Published: December 2023

River systems and their floodplains can be studied and evaluated according to different aspects. The natural processes of the Tisza were mostly influenced by the river training and levee construction works named after Vásárhelyi, as well as the main channel regulation works. After the construction of the embankments, the fluvial formation of the natural floodplains ceased, as these processes limited it to areas of the floodplain along the main channel. Another consequence of the river regulations is that the river is forced to deposit the sediment transported during the floods in this narrow floodplain causing increased filling up, so the role of floodplains in flood conveyance has increasingly been reduced. In this study, the author aimed to investigate the bed changes that occurred as a result of the river regulation works, as well as the sediment accumulation in the flood plain, focusing on a typical section of the Middle Tisza.

Is there a “made in Mexico” model for innovation transfer or diffusion among farmers?
Authors: Figueroa-Rodríguez Katia A. , García Vázquez J. Alberto
Published: December 2023

Objective: To determine the existence or absence of a model or several models for the transfer of innovations that have been developed and evaluated in Mexico.
Design/methodology/approach: Using the SCOPUS® metadatabase, a search was conducted with the words innovation AND farmer AND Mexico. It resulted in 70 articles, of which only 35 met the selection criteria.
Results: The articles used concepts, frames of reference, and, to a lesser degree, theories to support their research. The highest number of published cases dealt with the MasAgro technological hub model in maize and the GGAVATT model for group-oriented work in livestock.
Limitations on study/implications: Using a metadata base that is not open access limits the results, since technical reports, books, and other documents that might otherwise enrich the discussion are left aside.
Findings/conclusions: There is still much to be theorized in order to create new models adapted to other product systems that could promote technology transfer from the institutions of the sector and researchers to farmers.

Authors: Perez Rosales Alejandro , Ayala Garay Alma Velia , López Aranda Erika , Gabilan-Linares Eleodoro , Luna Esquivel Narciso
Published: December 2023

Objective: To estimate the fig (Ficus carica L.) yield in fertigation, through the use of linear regression, under the conditions of the Mixteca region of Puebla.
Design/Methodology/Approach: The plants were established in 10-L black polyethylene bags, using pine sawdust as a substrate. The treatments consisted of 6 variations of the following nutrient solution: 1.52 mg L-1 of potassium nitrate, 0.08 mL L-1 of phosphoric acid, and 0.38 mg L-1 of magnesium sulfate. Plant height, number of fruits per plant, and growth speed (cm day-1) were determined. A completely randomized experimental design was used and the levels of nutrient solution and orthogonal contrasts were subjected to a linear regression analysis, through the SAS® On Demand for Academics statistical package.
Results: The linear model describes the behavior of the data with an alpha of 0.01. A 60% nutrient solution level has a greater effect on growth and generates highly significant differences in both the plant height increase rate and plant height variables.
Study Limitations/Implications: This study includes only preliminary results; therefore, a longer period is necessary for data collection. Additionally, the following variables must also be included: yield and the content of nitrogen, phosphorus, potassium, magnesium in plant tissue.
Findings/Conclusions: Plant growth (height) can be estimated through the application of a linear model. An increasing linear behavior was observed in height with respect to the levels determined 50 days after the experiment was established. There are highly significant differences between the 60% dose and the rest of the treatments.

Authors: RODRIGUEZ SANCHEZ ILSE MONSERRAT , Castillo-Martínez Carlos R. , Velasco-Bautista Efraín , De La Cruz-Torres Eulogio
Published: December 2023

Objective: To carry out research focused on the germination response of mesquite (Neltuma laevigata) to different doses of gamma radiation (Cobalt 60), in order to obtain a higher germination response than with a non-irradiated seed.
Design/Methodology/Approach: Seeds had different collection times and identities. One set was collected in Durango (10 years) and another in Hidalgo (2 months). Both sets were exposed to sixteen different doses of gamma radiation and a control (non-irradiated); they were subsequently subjected to in vitro conditions using a Murashige and Skoog basal medium. They were monitored daily for two weeks in order to develop an accurate record of their germination.
Results: The best treatment for the radio-stimulation of germination in the Durango set was observed at 30 gray (12% higher than the control). Meanwhile, the Hidalgo set received 6 gray radiation (56% higher than the control).
Study Limitations/Implications: Only two different populations were evaluated for this study. Given the differences found between them, working with material from other origins would be ideal.
Findings/Conclusions: Low doses of gamma radiation cause an increase in the germination rate of seeds.

Authors: Córdova-Sánchez Samuel , Góngora-Cruz Karen G. , Hernández-Villegas Manuel M. , Salgado Velázquez Sergio , López-Castañeda Antonio , Castañeda-Ceja Raúl
Published: December 2023

Objective: To evaluate the response of sowing densities on agronomic parameters in the native mejen corn.
Design/Methodology/Approach: A randomized complete block design with four repetitions was used for the treatments: T1 (0.25 m between plants and two seeds per hole (80,000 plants ha-1)), T2 (0.50 m between plants and three seeds per hole (60,000 plants ha-1)), T3 (0.75 m between plants and four seeds per hole (53,333 plants ha-1)), and T4 (1 m between plants and five seeds per hole (50,000 plants ha-1)). The following variables were determined: plant height without male flower (PHWMF, cm), ear size (ES, cm), plant, bracts, and rachis dry biomass (t ha-1); number of bracts, rows per ear, grain per row, grains per ear, and grain yield (GY, t ha-1).
Results: Sowing densities influence the morphological response of plants, ears, and GY. The treatment with 80,000 plants ha-1 recorded a GY of 4.75 t ha-1 in traditional systems in Tabasco —greater than the regional average of 1.94 t ha-1.
Study Limitations/Implications: The architecture of native corn allows an increase in productivity, as a result of the use of high densities.
Findings/Conclusions: Although treatments with greater sowing distances obtained a lower number of grains per ear, this phenomenon is compensated by the greater number of plants per row that leads to higher grain yields.

Co-teaching continues to be a common method of instruction, allowing students with disabilities to engage in the general education curriculum. While there are numerous exemplars of excellent co-teaching, there is more that can be done to assist preservice teachers as they learn to bridge the gap between the student’s Individualized Education Program (IEP), the co-teaching setting, and the specially designed instruction students with disabilities need to make progress on their IEP goals in co-taught settings. This article provides a reflective matrix which faculty can use to scaffold novice teachers through co-assessment, co-planning, co-instructing, and co-reflecting by linking IEP goals to specially designed instruction (i.e., evidence-based and high leverage practices) and co-teaching models.
