The purpose of this work is to study the effect of kaolin particle size for the preparation of low cost ceramic membrane suspension and ceramic membrane structure. Kaolin particle size is categorized into two categories; i) ≤ 1µm and ii) ≥ 1 µm. The suspension is prepared via stirring technique under 1000 rpm at 60°C. The particle size of kaolin is characterized using field emission scanning electron microscope (FESEM) and the prepared suspension is characterized in term of its viscosity. Results indicate that the particle size gave significant effect to the viscosity of ceramic membrane suspension. Preliminary data showed that kaolin with particle size ≤ 1µm resulted ceramic membrane with dense structure.

Who Benefit from What Media? Examining Knowledge Gap Hypothesis on Environmental Knowledge In China
Authors: Ai Pengya , Huang Kanni , Li Wu
Published: August 2021

Environmental knowledge inequality is a barrier to
address environmental issues. This study explores the role of media use in
environmental knowledge gap in China, and the empirical evidence is analyzed by
using the secondary data from Chinese General Social Survey. OLS regression and
heterogeneity analysis revealed that internet use increases environmental
knowledge gap; radio use reduces environmental knowledge gap between people
with higher and lower levels of education. Newspaper and television use have
limited influence on environmental knowledge acquisition. However, newspapers
and television are more beneficial for people with lower levels of education,
but not those with higher levels.
Comparison of Children's Court Law with Child Criminal Justice System Law
Authors: B Herman
Published: August 2021

The purpose of this writing is to determine the examination of the child from the case of the arrangement of the Child Facing The Law in the Court according to the Law of the Children's Court with the Law of the Criminal Justice System of the Child. This research uses normative research supported by legal approach, analysis approach, and case approach. The results showed Law No. 3 of 1997 on The Children's Court was, in principle, born to protect and care for children in conflict with the law. However, it turns out that legally the Children's Court Law is not able to provide legal protection against Children Facing the Law. Therefore, Law No. 11 of 2012 on The Criminal Justice System of Children was born to replace the Children's Court Law. In the event of a change in the Law, there are striking differences in the handling of issues relating to children in the examination of criminal cases in court
Are Humans Mobot Minded? Some Implications of Embodied Cognitive Science for Cognitive Psychology.
Authors: Hill Stephen Robert
Published: August 2021

This chapter explores the idea that the design of the human mental architecture, like those of situated robots, is a product of integration, morphological, environmental, and interaction space constraints. Although much situated robotics research has focused on the generation of rather basic behaviours, rather than the kinds of complex cognitive abilities central to cognitive psychology, I want to suggest that we have much to learn from the synthetic methodology used in ECS.

The role of Primary Health Networks in cardiovascular disease prevention: A qualitative interview study
Authors: Cornell Samuel , Pickles Kristen , Crosland Paul , de Wet Carl , Trevena Lyndal , Bonner Carissa
Published: August 2021

Background: Since the inception of Primary Health Networks (PHNs) in Australia, it has been unclear what their role is regarding implementing chronic disease prevention activities in general practice. This study aimed to qualitatively explore the views of PHN staff on the role of PHNs in promoting prevention, with a focus on cardiovascular disease (CVD) prevention.Methods: Content analysis of PHN Needs Assessments was conducted to inform interview questions. 29 semi-structured interviews were conducted with 32 PHN staff, between June and December 2020, in varied roles across 18 PHNs in all Australian states and territories. Transcribed audio-recordings were thematically coded, using the Framework Analysis method to ensure rigour.Results: We identified three main themes about the role of PHNs in promoting, supporting, and improving CVD prevention. 1) Informal prevention: All respondents agreed the role of PHNs in prevention was indirect and, for the most part, outside the formal remit of PHN Key Performance Indicators (KPIs.) Nevertheless, prevention activities were conducted in partnership with external stakeholders, professional development and quality improvement programs, and PHN-funded data extraction and analysis software for general practice. 2) Constrained by financial incentives: Most interviewees felt the role of PHNs in prevention was contingent on the financial drivers provided by the Commonwealth government, such as Medicare funding and national quality improvement programs. 3) Shaped through competing priorities: The role of PHNs in prevention is a function of competing priorities. There was strong agreement amongst participants that the myriad competing priorities from government and local needs assessments impeded prevention activities.Conclusions: PHNs are well positioned to foster prevention activities in general practice and local communities. However, we found that PHNs role in prevention activities were informal, constrained by financial incentives, and shaped through competing priorities. Prevention can be improved through a more explicit prevention focus at Commonwealth government level. To optimise the role of PHNs therefore requires prioritising prevention, aligning it with KPIs, and supporting stakeholders like general practice.

How It Started, How It's Going: Why past research does not encompass pandemic-induced remote work realities and what leaders can do for more inclusive remote work practices
Authors: Torres Susan , Orhan Mehmet A.
Published: August 2021

This paper presents a critical evaluation of recently published studies that attempt to address remote work and virtual team challenges caused by the COVID-19 pandemic. In response to the increasing prevalence of remote work, these studies postulate a diverse set of recommendations to summarize what we know about remote work complexities and how to combat them. In this piece, we argue that most of these recommendations fail to serve the needs of leaders, virtual teams, and remote workers, as many of these recent publications gravely overlook the core challenges emerging from the forced nature of working remotely. Indeed, the unique nature of the pandemic poses particular challenges that go beyond previously identified ones. Thus, there is an urgent need to address unidentified obstacles and challenge misplaced recommendations to better equip executives and employees working remotely.
Ganzflicker reveals the complex relationship between visual mental imagery and pseudo-hallucinatory experiences: A replication and expansion
Authors: Reeder Reshanne R
Published: August 2021

Rhythmic visual flicker is known to elicit pseudo-hallucinations, making it an up-and-coming method to investigate anomalous perceptual experiences without pharmaceutical intervention. Ganzflicker is a full-screen visual flicker that can be experienced online. In the first exploratory paper (N = 204), we investigated whether people with different self-reported visual mental imagery abilities report different visual experiences in the Ganzflicker. Results showed that people with no-to-low imagery (aphantasia distribution) were much less likely to experience complex and vivid pseudo-hallucinations compared to people with moderate-to-vivid imagery (imagery distribution). In this follow-up, I collected data from 6664 individuals from around the world, replicated the main results of the previous study, and additionally found that people from the imagery distribution report more frequent pseudo-hallucinations for a longer duration than people from the aphantasia distribution. I also conducted new analyses across individual imagery vividness ratings. This revealed a dramatic increase in susceptibility to pseudo-hallucinations from reports of “no imagery” to “low imagery vividness” within the aphantasia distribution. There is a positive linear relationship between imagery vividness and pseudo-hallucination vividness, whereas the relationship between imagery vividness and pseudo-hallucination complexity is categorical, as indicated by a jump in the likelihood to experience complex pseudo-hallucinations from the aphantasia distribution to the imagery distribution with no within-distribution variations. Finally, word cloud analyses of written descriptions of Ganzflicker experiences revealed unique language used for each distribution. In sum, Ganzflicker is an accessible, efficient, and effective method of investigating multiple aspects of anomalous perceptual experiences in people with different mental imagery abilities.
“Fringe” beliefs aren’t fringe
Authors: Martí Louis , Conover Adam , Kidd Celeste
Published: August 2021

COVID-19 and the 2021 U.S. Capitol attacks have highlighted the potential dangers of pseudoscientific and conspiratorial belief adoption. Approaches to combating misinformed beliefs have tried to “pre-bunk” or “inoculate” people against misinformation adoption and have yielded only modest results. These approaches presume that some citizens may be more gullible than others and thus susceptible to multiple misinformed beliefs. We provide evidence of an alternative account it’s simply too hard for all people to be accurate in all domains of belief, but most individuals are trying. We collected data on a constellation of human beliefs across domains from more than 1,700 people on Amazon Mechanical Turk. We find misinformed beliefs to be broadly, but thinly, spread among the population. Further, we do not find that individuals who adopt one misinformed belief are more likely to engage in pseudo-scientific or conspiratorial thinking across the board, in opposition to “slippery slope” notions of misinformation adoption.
Culture and ideal affect: Cultural dimensions predict Spotify listening patterns
Authors: Vidas Dianna , McGovern Hugh , Nitschinsk Lewis
Published: August 2021

Ideal affective states tend to differ across cultures - those from East Asia typically pursue low-arousal positive affect, while Latin American and Western European individuals pursue high-arousal positive affect. Previous research has shown that music may be an effective way to regulate affective state; however, this is seldom examined through the lens of cultural differences. Furthermore, the relationships between valence and arousal of music preference and specific cultural dimensions remains underexplored. As such, this study examined cultural differences in ideal affect through music preference on Spotify. In total, 32,400 songs were drawn from weekly charts across 12 months on Spotify, from 27 countries (three culturally similar regions; Western-European, East-Asian, and Latin-American). The valence and arousal of music from these countries was examined between cultures, and within the context of six cultural dimensions. Consistent with theories around cross-cultural ideal affect, we found that Western-European countries preferred higher arousal music than East-Asian countries, and Latin American countries preferred the highest arousal music. In addition, both Western countries and East Asian countries showed a similar preference for neutral valence music. This contradicted the expected universal preference for positive valence, which was evident only for the Latin American countries. Finally, high uncertainty avoidance was associated with positive valence and high arousal in music, and positive valence was also associated with higher indulgence, and lower long-term orientation. We provide evidence that cultural differences in ideal affect map on to cross-cultural music preferences, and that these preferences relate to several cultural dimensions.
Latent diversity in human concepts
Authors: Martí Louis , Wu Shengyi , Piantadosi Steven T. , Kidd Celeste
Published: August 2021

Many social and legal conflicts come down to differences in semantics. Yet, semantic variation between individuals and people’s awareness of this variation have been relatively neglected by experimental psychology. Here, across two experiments, we quantify the amount of agreement and disagreement between ordinary semantic concepts in thepopulation, as well as people’s meta-cognitive awareness of these differences. We collect similarity ratings and feature judgements, and analyze them using a non-parametricclustering scheme with an ecological statistical estimator to infer the number of different meanings for the same word that is present in the population. We find that typically atleast ten to twenty variants of meanings exist for even common nouns, but that people are unaware of this variation. Instead, people exhibit a strong bias to erroneously believe that other people share their particular semantics, pointing to one factor that likely interfereswith political and social discourse.
Gender differences among active reviewers: an investigation based on Publons
Authors: Zhang Lin , Shang Yuanyuan , HUANG Ying , Sivertsen Gunnar
Published: August 2021

Peer review of scientific manuscripts before publication is essential in scholarly publishing, and most active researchers hold relationships with a number of journals as both an author and a reviewer. There have been several studies focusing on gender balance in academic research and authorship, but fewer studies on our role as reviewers. Publons is a commercial website run by Clarivate Analytics that allows researchers to track and verify their peer review activities and be recognized for it. The platform features over 2 million researchers and 6.9 million reviews for more than 5,000 partnered journals, listing the most active reviewers as “top reviewers”. Our study focuses on gender representation in this ‘top reviewer’ group while also looking at the countries, regions and research fields they represent, as well as the relationship between their roles as authors and reviewers. The results show that male reviewers dominate in almost all countries, regions, and research fields. Male reviewers generally contribute to review work more frequently than females; however, female reviewers write longer reviews. The correlations between reviewing activity and research activity are generally weak overall and within specific research fields. This may reflect that active reviewers are not necessarily the most productive researchers in their fields. What clearly emerges from our results is the need for more concern over gender representation in the quality assurance and gatekeeping functions of scholarly publishing.
Artificial Fairness? Trust in Algorithmic Police Decision-Making
Authors: Hobson Zoe , Yesberg Julia , Bradford Ben , Jackson Jonathan
Published: August 2021

Objectives: Test whether: (1) people view a policing decision made by an algorithm as more or less trustworthy than when an officer makes the same decision; (2) people who are presented with a specific instance of algorithmic policing have greater or lesser support for the general use of algorithmic policing in general; and (3) people use trust as a heuristic through which to make sense of an unfamiliar technology like algorithmic policing.Methods: An online experiment tested whether different decision-making methods, outcomes and scenario types affect judgements about the appropriateness and fairness of decision-making, and the general acceptability of police use of this particular technology. Results: People see a decision as less fair and less appropriate when an algorithm decides, compared to when an officer decides. Yet perceptions of fairness and appropriateness were strong predictors of support for police use of algorithms, and being exposed to a successful use of an algorithm was linked via trust in the decision made to greater support for police use of algorithms.Conclusions: Making decisions solely based on algorithms might damage trust, and the more police rely solely on algorithmic decision-making, the less trusting people may be in decisions. However, mere exposure to the successful use of algorithms seems to enhance the general acceptability of this technology.
Early experience of stereotactic biopsy of brain lesion in tertiary centre of Nepal
Authors: Jha Binit Kumar , Jha Prabhat , Jha Rajiv , Bista Prakash
Published: August 2021

Background

 Stereotactic surgery or stereotaxy is a minimally invasive form of surgical intervention which makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc. Though it was developed a long time ago as a useful adjunct to brain lesions evaluation, use in Nepal is quite recent.

Materials and Methods

The study included eight patients who underwent frame based stereotactic biopsy and pathological evaluation of specimen at National Academy of Medical Sciences (NAMS).

Results

Out of eight patients the results were positive in seven patient and negative in one patient.

Conclusions

 The basic advantages of stereotaxy were realized in our cases with minimal morbidity and no mortality. Craniotomy for biopsy could be avoided.
Primary Intramedullary Hydatid cyst
Authors: Thapa Ashish Jung , Tandon Asheesh , Agrawal Alok
Published: August 2021

Hydatid cysts or Hydatid disease is caused by Echinococcus granulosus infestation. Dogs, wolves, and other carnivores are the definitive host, and human being the accidental intermediate hosts. This disease commonly involves the liver and lungs and rarely involves other organs of the body. Primary intramedullary hydatid cysts are extremely rare and few cases before us have been reported in the literature. There is no pathognomonic sign or symptom for spinal hydatid cyst, mostly compression related symptoms, e.g. radiculopathy, myelopathy, local pain, and pathologic fractures are found. So preoperative diagnosis of spinal hydatid requires the correlation of all the aspects including clinical features, radiology, and lab reports.  Surgical management is the best treatment for spinal hydatid cyst with complete excision without cyst rupture being the primary target along with complete neural elements decompression. Here we report a case of a 26-year old male with paraparesis with MRI finding directing towards D9-D10 intramedullary cystic lesion (cystic astrocytoma) which was completely excised and histopathology report favored intramedullary hydatid cyst.

Brugada syndrome is an inherited cardiac arrhythmia that follows autosomal dominant transmission and can cause sudden death. This paper reported a case of Brugada syndrome in a 43-year-old male patient with no clinical symptoms. Brugada-type 2-ECG changes were accidentally detected. Flecainide test was done and proved positive. Gene analysis revealed a novel missense mutation in the SCN5A gene with a genetic variation of D252N. This novel mutation has not been reported on any genetic databases related to Brugada syndrome. Functional protein analysis software suggested that the mutation occurs in the highly conserved gene and probably has a damaging effect. This is the first Brugada syndrome case reported with a mutation in the SCN5A gene in Vietnam.

Atrophic gastritis is one of the most common gastric diseases, and many risk factors may increase the risk. This study aimed to assess the relationship between dietary factors and clinical symptoms of patients with atrophic gastritis. A cross-sectional study was conducted from October 2018 to October 2020 in the Center of Gastroenterology and Hepatology of Bach Mai Hospital with a total of 3508 atrophic gastritis patients aged ≥40 years (female/male ratio was 1.68). All patients were interviewed based on a designed questionnaire and underwent a gastroscopy procedure. The most common symptoms were epigastric pain (73.9%), belching/heartburn (42.4%), the feeling of fullness (41%), reflux symptom (15.4%). A majority of patients had mild atrophic gastritis (C1, C2) (80.4%), followed by moderate atrophic gastritis (C3, O1) (17%), and severe atrophic gastritis (O2, O3) (2.6%). A diet with much deep-fried or grilled food increased the risk of epigastric pain (OR 1.343; 95%CI 1.002-1.801); diets with much meat or nuts increased the risk of the feeling of fullness (meat: OR 1.296; 95%CI 1.100-1.526 and nuts: OR 1.316; 95%CI 1.033-1.676), and belching/heartburn (meat: OR 1.243; 95%CI 1.058-1.461 and nuts: OR 1.376; 95%CI 1.082-1.751). Diets with much salt or nuts increased the risk of reflux symptoms (salt: OR 1.359; 95%CI 1.055-1.752 and nuts: OR 1.532; 95%CI 1.023-2.293). A diet with many vegetables was a protective factor that can help to decrease the risk of moderate and severe atrophic gastritis (OR 0.616; 95%CI 0.403-0.941). In conclusion, diets and food types are factors that affect the risk of clinical symptoms among patients with atrophic gastritis, so the action of adjusting diets and daily food also play an important role in atrophic gastritis.

The striped catfish, Pangasianodon hypophthalmus, is one of the most economically important aquaculture species in Vietnam. This study developed 26 novel microsatellite markers from the draft genome of the striped catfish to assess the genetic diversity of three wild populations of the striped catfish (Bien Ho, Cuu Long, and Kratie) for establishing the breeding program. The study exhibited that 6 out of 26 loci had significantly high null allele frequency and deviated from Hardy - Weinberg equilibrium; thus, they were eliminated for further analysis. Across 20 loci without null alleles, a total of 255 different alleles was identified, ranging from 7 to 21 alleles per locus, with many unique alleles for each population. The results based on 20 loci revealed the mean polymorphic information content PIC=0.783; the mean observed heterozygosity Ho=0.809; the mean expected heterozygosity He=0.812; inbreeding coefficient Fis=-0.0147 (Fis<0). The results indicated that the striped catfish populations have high genetic diversity and are suitable for selective breeding. The Analysis of Molecular Variance (AMOVA) and comparison of genetic distances showed significant genetic differentiation among three populations while the Kratie population was distant from the others.

Background: catheter mediated infections are mainly caused by Staphylococci, the treatment of these infections is challenging because of biofilm formation. Methods: A microtiter plate biofilm assay was used to study the in vitro activity of Vancomycin, Ofloxacin and Levofloxacin on preformed biofilms of 30 stains of Staphylococcus isolated from peritoneal dialysis catheters and fluids at concentrations like those used intraperitoneally. Results: The in vitro action of the three antibiotics on preformed biofilms was statistically significant. it was significantly higher for Ofloxacin and Levofloxacin rather than that of Vancomycin. Discussion: the results demonstrate the effectiveness of the three antibiotics at concentrations like those used intraperitoneally and the superiority of Fluoroquinolones activity on Staphylococcal biofilms, these results correlate with the conclusions of other authors.

Introduction : The risk of atherosclerosis increases when elevated blood cholesterol levels. Flavonoids may help inhibit the absorption of fat, which indirectly helps in lower cholesterol levels.Flavonoids are widely available on the Andrographis paniculata leaves (APL).This study aims to examine the effect of flavonoids in APL stewto lower the cholesterol levels. Material and Methods: This research was carried out using five different groups of Wistarrats. Each group consists of five Wistar rats. Group (K-) received normal diet, group (K+) received atherogenic diet and three groups of atherogenic diets rats that pre-treated with three different doses (0.6, 1.2, and 2.4g/day) of APL leaf stew. APL stew is orally gavaged for 60 days. The cholesterol blood serum was analyzed using the CHOD-PAP method. Statistical analysis using One-Way ANOVA and Post-Hoc Tukey. Results : The results showed a significant difference in cholesterol levels between the groups of theatherogenic diet with other treatment groups (p = 0.000).When compared with thenormal diet group, treatment with 1.2 g and 2.4 g of APL produce cholesterol levels not significantly different.APLstew has been shown to inhibit the elevated levels of serum cholesterol in male Wistar rats that fed with the atherogenic diet which contributed 54.8%.While fat intake increased the cholesterol level by 16.3%.Both APL stew and fat dose intake together affect the formation of cholesterol with a contribution of 69.2%. Conclusion : The dose that is considered as the most effective in lowering cholesterol is 2.4 g becauseit producescholesterol level closest to normal.

Published: August 2021

Seismic sensors are installed on offshore platforms for recording earthquakes. Technological pipelines are being built, to service the operation of the field. This article is devoted to ensuring the safety of technological pipelines. It deals with the analysis of data on a seismic event based on the correlation of the seismic impact recorded on the platform. Since the process pipelines are located near the platform, using statistical analysis methods, correlation analysis of data recorded at a distance of about 200 m and using fuzzy logic methods, we can have an idea of the degree of impact of the earthquake on the surrounding process pipelines.

ROAD TRAFFIC ACCIDENTS RATE IN TYUMEN: 21th CENTURY TRENDS
Authors:   Industrial University of Tyumen, Petrov Artur I.
Published: August 2021

The article deals with the problems of road traffic accidents rate in a large Russian city Tyumen in the late 20 – early 21st centuries. The statistics describes the actual road safety (RS) in Tyumen in 1998–2020. The article presents models based on specific data from Tyumen, that confirm R. Smid's law on the relationship between motorization and the estimated characteristics of RS – human risk (HR) and transportation risk (TR). The trends of HR and TR formation over time for the Tyumen transport system correspond to the stage of a qualitative transition from the third to the fourth RS paradigm. The leading countries are characterized by the fifth paradigm of RS in the field of ensuring the safety of the population today. This is a system of views based on the ideas of the highest value of human life and the need to limit transport mobility, transfer it to another quality. Tyumen with the values of the third and fourth paradigms of RS in practice, so far in all objective manifestations repeats the experience of cities in other countries that passed this stage 20–30 years ago.
Clinical and histopathological principles for the diagnosis of a recurrent paraganglioma of the jugular foramen initially diagnosed as a middle ear adenoma: illustrative case

Published: August 2021

BACKGROUND

Paragangliomas (PGLs) are rare neoplasms that may be associated with hereditary PGL syndromes and variable risk of metastasis. Middle ear adenomas are extremely rare tumors with no known hereditary predisposition and extremely low risk of metastasis. Although often easily differentiated, they may share clinical and pathological features that misdirect and confuse the diagnosis.

OBSERVATIONS

The authors discussed a 35-year-old woman with left-sided hearing loss and bleeding from the external ear canal who presented to an outside hospital. She underwent resection of a middle ear and mastoid mass, initially diagnosed as a middle ear adenoma with neuroendocrine features, with later mastoidectomy and ligation of the sigmoid sinus with microsurgical excision of persistent tumor in the jugular foramen and temporal bone. Histopathologically, her tumor was vascular, composed of benign-appearing epithelioid cells with “salt and pepper” neuroendocrine chromatin arranged in vague nests. Lesional cells were GATA3-immunopositive, glucagon-negative, and succinate dehydrogenase-immunonegative, consistent with PGL rather than middle ear adenoma, and required further workup for hereditary PGL syndromes.

LESSONS

This case demonstrates potential challenges in differentiating a PGL from a middle ear adenoma. The authors offer clinical, histopathological, and imaging principles to aid in diagnosis and workup.

Метаболічний стан, що передує розвитку цукрового діабету 2-го типу (ЦД2) — предіабет, який характеризується резистентністю до інсуліну та первинною або вторинною дисфункцією β-клітин. У це поняття входять такі зміни вуглеводного обміну, як порушення глікемії натщесерце і порушення толерантності до глюкози. Біомаркерами предіабету є: рівні HbA1c та глікованого альбуміну; стан толерантності до глюкози; 1,5 ангідроглюцитол; фруктозамін. Нові маркери включають: адипонектин; фетуїн A; ліпопротеїн α; тригліцериди (ТГ); рівні ліпопротеїнів високої щільності (ЛПВЩ), низької щільності (ЛПНЩ) та дуже низької щільності; співвідношення ТГ/ЛПВЩ та ЛПНЩ/ЛПВЩ; загальний рівень холестерину; церамід; феритин; асоційовані з лектином серинові протеази; тромбоспондин 1; ацил-карнітини; мікроРНК; С-реактивний білок; фібриноген; інтерлейкін 18 (IL‑18). Фактори ризику розвитку предіабету: близькі родичі з ЦД2; етнічна приналежність; серцево-судинні захворювання (ССЗ); гіпертонія; вміст холестерину ЛПВЩ та ТГ; у жінок синдром полікістозних яєчників; фізична неактивність; наявність сильного ожиріння; чорний акантоз та/або папіломи на шкірі. Метаболічний синдром (МС) — це сукупність факторів ризику, які визначають схильність до розвитку ЦД2 та ССЗ. Визначено 5 факторів ризику МС: високий рівень ТГ; низький вміст ЛПВЩ-С; високий артеріальний тиск та висока концентрація глюкози натщесерце або раніше виявлений ЦД2. Додатковими чинниками є гіпертонія; наднизький рівень ЛПВЩ-С; центральне ожиріння; високе співвідношення талії до стегна та мікроальбумінурія. Пізніше були запропоновані, як можливі додаткові чинники МС: гіперурикемія, мікроваскулярна ангіна та підвищенийрівень інгібітора активатора плазміногену. Зважаючи на глобальність предіабету, високі показники прогресування ЦД2 та підвищений ризик мікро- і макроваскулярних ускладнень та смерті, зусилля, зосереджені на запобіганні прогресування діабету та його ускладнень мають вирішальне значення. Для профілактики та затримки діабету виявились ефективними активація способу життя і медикаментозна терапія.
