BackgroundAn increasing number of studies have focused on the role of gut microbiota in the treatment of ADHD, but its related molecular mechanisms are not yet clear, and there is still room for development of studies targeting this area. This study analyzes publications from 2012 to 2021 in a comprehensive and multi-faceted visualization, with the aim of grasping the existing research profile and guiding scholars to make more in-depth studies.MethodsThe 1,677 articles and 298 review articles on gut microbiota in ADHD were retrieved from the Web of Science Core Collection. CiteSpace, VOSviewer, Microsoft Excel 2019, Scimago Graphica, Bibliometrix and Pajek metrics software were used for visualization and analysis of the included literature.ResultsOn August 3, 2022, a total of 1975 English-language articles on gut microbiota in ADHD were retrieved from Web of Science Core Collection (WoSCC) from January 2012 to December 2021, with a steady upward trend in the number of articles published in this field over the decade. The top three countries in terms of the number of articles published are the United States, China, and Spain. Meanwhile, CONSEJO SUPERIOR DE INVESTIGACIONES CIENTIFICAS CSIC, UNIV OF CALIFORNIA SYSTEM, and UDICE FRENCH RESEARCH UNIV have made significant contributions in this field. In the analysis of the published journals, PLoS One was not only the first in terms of number of articles published but also the most cited. Wang J was the most prolific author and CAPORASO JG ranked first in terms of co-cited authors. In addition, “Diet rapidly and reproducibly alters the human gut microbiome,” published by David LA et al., has the highest citation frequency in this field. The most frequently occurring keyword was “gut microbiota.”ConclusionThe results of this paper clarify the current status of research on gut microbiota in ADHD. Based on the research on the mechanism of gut microbiota in other diseases, there is reason to believe that the exploration of gut microbiota in ADHD must be increasingly mature. And the study speculates that future research may focus on “nutrition supplements,” “lipid metabolism,” and “gut brain axis.” It is imperative to promote a closer international cooperation among scholars in this field.

ObjectiveTo study the brain network mechanism of cognitive control in the elderly with brain aging.Materials and methods21 normal young people and 20 elderly people were included in this study. Mini-mental State Examination and functional near-infrared spectroscopy (fNIRS) synchronous judgment test (including forward tests and reverse judgment tests) were performed on all subjects. To observe and compare differences in brain region activation and brain functional connectivity between subjects and forward and reverse trials by recording functional connectivity (FC) in different task paradigms and calculating bilateral prefrontal and primary motor cortical (PMC) areas.ResultsIn the forward and reverse judgment tests, the reaction time of the elderly group was significantly longer than the young group (P &lt; 0.05), and there was no significant difference in the correct rate. In the homologous regions of interest (ROI) data, the FC of PMC and prefrontal cortex (PFC) in the elderly group was significantly decreased (P &lt; 0.05). In the heterologous ROI data, except for left primary motor cortex (LPMC)-left prefrontal cortex (LPFC), the other PMC and PFC of the elderly group were significantly lower than the young group (P &lt; 0.05) while processing the forward judgment test. However, the heterologous ROI data of LPMC-right prefrontal cortex (RPFC), LPMC-LPFC and RPFC-LPFC in the elderly group were significantly lower than the young group (P &lt; 0.05) while processing the reverse judgment test.ConclusionThe results suggest that brain aging affected degeneration of whole brain function, which reduce the speed of information processing and form a brain network functional connection mode different from that of young people.

PurposeSalmonella infection is a key global public health concern and has lead to an increased economic burden on society. We investigated the epidemiological characteristics and antimicrobial resistance profiles of clinically isolated Salmonella strains in Guangzhou Women and Children's Medical Center.Patients and methodsThis was a retrospective study of 1,338 Salmonella strains collected from children in Guangzhou Women and Children's Medical Center during 2016 to 2021.ResultsThe results revealed that 1,338 cases of Salmonella were mainly isolated from feces and blood samples. The age distribution was dominated by infants under 3 years old. The seasonal distribution was high in summer and autumn. 48 serotypes were detected, and S. typhimurium (78.7%) was the predominant serogroup. The results of antimicrobial susceptibility showed that the highest resistance was observed in ampicillin (84.5%), while lower resistance was observed in piperacillin/tazobactam, cefoperazone/sulbactam and ciprofloxacin. The antimicrobial resistance rate of fecal isolates was higher than that of blood isolates. The five-year average detection rate of multi-drug resistant Salmonella was 8.5% (114/1338) and the MDR rate of S. typhimurium was the lowest (6.9%; 73/1053).ConclusionWe concluded that antibacterial treatment should be carefully selected according to serotype and antimicrobial sensitivity results in children. Antimicrobial resistance monitoring for multi-drug resistant Salmonella is still required.

BackgroundKawasaki disease (KD) is a systemic vasculitis affecting young children, which may lead to coronary artery aneurysm (CAA). The optimal timing of serial echocardiography in patients with uncomplicated KD is debated.ObjectivesTo assess changes in coronary artery Z-scores from the initial diagnosis, two weeks, eight weeks, and one year following diagnosis and adverse cardiac events in children diagnosed with KD without initial CAA.MethodsRetrospective chart reviews of four referral centers in Thailand were conducted of all children who were diagnosed with KD without initial CAA (coronary artery Z-score &lt; 2.5) between 2017 and 2020. Eligibility criteria included the absence of congenital heart disease and patients with available echocardiographic evaluations at baseline and at eight weeks of illness. The two-week and one-year echocardiographies were reported. Adverse cardiac events at one year from diagnosis were explored. The primary outcome was a maximal coronary Z-score on the follow-up echocardiography at eight weeks and one year.ResultsOf 200 patients diagnosed with KD, 144 patients (72%) did not have CAA. A total of 110 patients were included in the study. The median age was 23 months (IQR, 2–39 months) and 60% were male. Fifty patients (45.5%) had incomplete KD, and four (3.6%) received a second intravenous immunoglobulin treatment. Of 110 patients, 26 patients (23.6%) had coronary ectasia (Z-score of 2–2.49) on their initial echocardiographic examination. Sixty-four patients were evaluated in two-week echocardiographic studies, which showed four new small CAAs and five coronary ectasia. At 8 weeks, 110 patients had undergone complete echocardiographic studies. No patient had residual CAAs. Only one patient had persistent coronary ectasia that regressed to normal within one year. At one-year follow-up (n = 90), no cardiac events were reported.ConclusionNew CAA in-patients with KD who had no previous CAA in their initial echocardiography are rare. In addition, patients who had normal echocardiographic follow-up at two weeks or eight weeks mostly continued to be normal at one year. The optimal timing of the echocardiographic follow-up should be at two to eight weeks in patients without initial CAA, who still have a coronary artery Z-score &lt; 2 at the second echocardiography.Trial registration: TCTR20210603001.

IntroductionBrucellosis, a serious public health issue affecting animals and humans, is neglected in West Africa (WA).MethodsIn the present study, bio-typing, multi-locus sequence typing (MLST), multiple-locus variable-number tandem repeat analysis (MLVA), and whole genome sequencing single-nucleotide polymorphism (WGS-SNP) analysis were used to characterize the Brucella abortus (B. abortus) strains from WA.ResultsAll of the 309 strains analyzed in this study were extracted and downloaded from the international MLVA bank and were from 10 hosts (cattle, humans, ovine, buffalo, dromedaries, horse, sheep, zebu, dog, and cat) distributed in 17 countries in WA. Based on the bio-typing, three biovars, dominated by B. abortus bv.3, were observed and reported across seven decades (1958–2019). With MLST, 129 B. abortus strains from the present study were sorted into 14 STs, with ST34 as the predicted founder. These 14 STs clustered into the global MLST data into three clone complexes (C I–C III) with the majority of strains clustering in C I, while C II forms an independent branch, and C III harbors three STs shared by different continents. These data revealed that most cases were caused by strains from native lineages. According to the MLVA-11 comparison, 309 strains were divided into 22 MLVA-11 genotypes, 15 of which were unique to WA and the remaining seven had a global distribution. MLVA-16 analysis showed that there were no epidemiological links among these strains. Based on the MLVA data, B. abortus strains from WA have high genetic diversity, and predominated genotypes were descended from a native lineage. While the MLVA-16 globally highlights that the dominant native and few introduced lineages (from Brazil, the USA, South Korea, Argentina, India, Italy, Portugal, the UK, Costa Rica, and China) co-driving the B. abortus ongoing prevalence in WA. The high-resolution SNP analysis implied the existence of introduced B. abortus lineages, which may be reasonably explained by the movement and trade of dominant hosts (cattle) and/or their products.DiscussionOur results indicated that B. abortus strains in WA consist of native and introduced strains that necessitate control such as vaccination, testing, slaughtering, and movement control by the relevant country authorities to reduce brucellosis in livestock.

It is significant for revealing the formation mechanism of the lunar Mascon to invert the refined 3-D lunar crust and upper mantle structure of the Mare Serenitatis. As the development of space exploration technology, lunar gravity data has advantages of high accuracy and resolution, which can be used to invert the lunar crust and upper mantle structure. However, gravity anomaly reflects all anomalous material during the whole Moon’s interior, and its vertical structure recognition capability is poor. Thus, this paper adopts wavelet multi-scale analysis method to decompose the gravity anomaly in the Mare Serenitatis for enhancing vertical resolution, and the corresponding field source depths of the decomposed gravity anomalies are further estimated by power spectrum method. Subsequently, the layered densities and the crust-mantle interface depth of the Mare Serenitatis are inverted. The research results show that the 3-D morphological character of two large high-density materials in the Mare Serenitatis is clearly depicted. The southwest high-density material with its bottom center at approximately (15°E, 25°N) has the depth range of 50 km–80 km and the maximum diameter of approximately 150 km. As for the southeast high-density material, its bottom center is located at approximately (23°E, 25°N), the depth range is 30 km–60 km and the maximum diameter is approximately 100 km. Another new finding is that the crust-mantle interface uplift has obviously fallen back in the center of the Mare Serenitatis. The high-density materials and crust-mantle interface uplift may together promote the formation of the Mascon in the Mare Serenitatis.

IntroductionThe right to food is a human right. Food insecurity refers to the inability to prepare proper and healthy food. Food insecurity is associated with adverse outcomes among households. To determine the prevalence of food insecurity, its level, and the factors affecting it among households covered by health centers in marginalized areas of Birjand city.MethodsThis descriptive-analytical cross-sectional study was performed on 396 households aged 20-60 years covered by health centers in the marginal areas of Birjand in 2019. We used a 9-item Household Food Insecurity Access Scale (HFIAS) questionnaire. Chi-square, Fisher, and logistic regression analyses were performed using SPSS 22 software at a significance level of less than 0.05.ResultsThe mean age of the subjects was 34.04 ± 9.41 years. In total, 48% of the subjects had a level of food insecurity, of which 7.6% had severe, 12.6% moderate, and 27.5% mild insecurity. The prevalence of food insecurity in families with low members and higher levels of education is significantly lower (p &lt; 001). Backward Logistic regression showed that illiteracy (OR: 8.26) and primary education (OR: 2.65), rental housing status (OR: 1.69), lower-income levels being covered by support organizations (OR: 3.13), employed members between 3-4 and more than five (OR: 2.73 and 2.93, respectively), and low weight (OR: 2.55) were associated with food insecurity. The prevalence of food insecurity in this study was high.ConclusionThe high prevalence of insecurity in studied households is an alarm for the authorities, which can be due to poverty and the low level of nutritional literacy of households' heads and mothers. Helping to improve the quality of life of families and food insecurity of households by improving physical and economic access, increasing literacy and nutritional culture, and reducing the burden of non-communicable diseases related to nutrition is a suggested solution.

Published: March 2023

BackgroundTo explore the optimal frequency for pediatric extracorporeal shock wave lithotripsy (ESWL) in the treatment of upper urinary stones.MethodsA systematic literature search was undertaken using PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials databases to identify eligible studies published before January 2023. Primary outcomes were perioperative efficacy parameters, including ESWL time, anesthesia time for ESWL sessions, success rates after each session, additional interventions needed, and treatment sessions per patient. Secondary outcomes were postoperative complications and efficiency quotient.ResultsFour controlled studies involving 263 pediatric patients were enrolled in our meta-analysis. In the comparison between the low-frequency and intermediate-frequency groups, we observed no significant difference as regards anesthesia time for ESWL session (WMD = −4.98, 95% CI −21.55∼11.58, p = 0.56), success rates after ESWL sessions (first session: OR = 0.02 95%CI −0.12∼0.17, p = 0.74; second session: OR = 1.04 95%CI 0.56∼1.90, p = 0.91; third session: OR = 1.62 95%CI 0.73∼3.60, p = 0.24), treatment sessions needed (WMD = 0.08 95%CI −0.21∼0.36, p = 0.60), additional interventions after ESWL (OR=0.99 95%CI 0.40∼2.47, p = 0.99) and rates of Clavien grade 2 complications (OR = 0.92 95%CI 0.18∼4.69, p = 0.92). However, the intermediate-frequency group may exhibit potential benefits in Clavien grade 1 complications. In the comparison between intermediate-frequency and high-frequency, the eligible studies exhibited higher success rates in the intermediate-frequency group after the first session, the second session and the third session. More sessions may be required in the high-frequency group. With respect to other perioperative, postoperative parameters and major complications, the results were similar.ConclusionsIntermediate-frequency and low-frequency had similar success rates and seemed to be the optimal frequency for pediatric ESWL. Nevertheless, future large-volume, well-designed RCTs are awaited to confirm and update the findings of this analysis.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier: CRD42022333646.
Argumentativeness of Bewildering and Reception Effectiveness in Models of Poetic Heritage
Authors: Bilal Doha 
Published: March 2023

This research laid out an objective represented in pinpointing the lurking places of bewilderment and ways of persuasion in models of the poetic heritage of poets who held the flag of bewilderment and creativity, so they immortalized their poems, which implied deep vision and inclusiveness of the ego, the universe, and things.
The research also concerned itself with the recipient, and the impact poetry has in dazzling him, and then his submission both emotionally and rationally to the poetic say purport. The research concluded that bewilderment has its causes relevant to text- characterizing elements, embodied in shifting, breaking expectation horizon, and functionalization of various forms of allegory.
These reasons do make the poetic text excellently wonderful and argumentative; as they make the recipient partner and effective intellectual discussant, when he preoccupies his thought in reflection and thinking, and this dazzling advanced the recipient up because it is not a transient spiritual agitation; as it allures the recipient through a wonderful argumentative context.
Superstitious Thinking and its Relation to the Extent of Parents’ Acceptance of their Children Receiving the Coronavirus (Covid-19) Vaccine
Authors: Mohammed Shatanawi Hadeel 
Published: March 2023

Objectives: This study aimed at identifying superstitious thinking and its relation to the extent of parents’ acceptance of their children receiving the Coronavirus (Covid-19) vaccine.
Methods: The descriptive approach was used, and responses of 277 individuals on a scale of superstitious thinking were recorded and analyzed by calculating the arithmetic means and standard deviations of the scale items followed by t-test analysis.
Results: The results of this study indicated that there are nine statistically significant relations between the gender of the parents in Hafr Al-Batin and their level of beliefs in superstitious thinking. Specifically, seven relations showed that fathers' beliefs in superstitious thinking are stronger than the mothers' beliefs. Further, thirteen statistically significant relations are found among the conviction of parents in Hafr Al-Batin that their children receive the Coronavirus vaccine and the number of doses, and the beliefs in superstitious thinking. Furthermore, two relations showed that the more parents in Hafr Al-Batin believe in superstitious thinking, the more they are not convinced that their children would receive the Coronavirus vaccine, and of giving them multiple doses.
Conclusions: The results recommended involvingluential figures in societies to correct some superstitious beliefs, and to conduct more studies on superstitious thinking and link it to other variables such as educational level and residential area or age group.

Published: March 2023

The economic development of the Papua Province has begun to be seen with the development of several regional potentials. However, these favorable conditions do not make the economic development of each Regency/City more evenly distributed. For this reason, research on inequality in development between districts in Papua Province is very necessary. Furthermore, the objective of this study is to analyze the level of development inequality and economic growth between districts/cities in Papua Province in 2018-2021.
This research was conducted from November 2021 to February 2022. The data used are secondary data from the Central Statistics Agency (BPS) of Papua Province; with the variables used: GRDP of Papua Province at Constant Prices, GRDP of Regency/City of Papua Province, Total Population of Papua Province, and Total Population of Regency/City of Papua Province. Analysis of the data used in this study is the analysis of regional inequality (Williamson Index) and analysis of the regional approach (Klassen Typology) with processing using Microsoft Excel.
Based on the results of the research and discussion, the conclusions of this study are that: inequality that occurs in Papua Province between districts/cities in the 2018-2021 period had increased. The average Williamson Index score in Papua Province in the research period was 0.585256472 (or 0.59) with high inequality criteria. And, the classification of districts/cities based on economic growth and per capita GRDP in Papua Province uses the Klassen Typology analysis tool for the 2018-2021 period with a regional approach divided into four existing classifications. Developed and fast-growing regions, namely Merauke, Sarmi, Boven Digoel, Bintang Mountains, Nabire, Keerom, Supiori, Waropen, and Jayapura Regencies; developed but depressed areas, namely Kota Jayapura, Mamberamo Raya, and Mimika; areas developing fast but not developing, namely Puncak, Mappi, Biak Numfor, Central Mamberamo, Nduga, Lanny Jaya, Dogiyai, and the Yapen Islands; and relatively underdeveloped areas, namely Paniai, Jayawijaya, Deiyai, Yalimo, Tolikara, Puncak Jaya, Yahukimo, and Intan Jaya.
