Published: March 2022

Type 2 diabetes mellitus is often characterized by hyperglycemia as a result of increased insulin resistance in hepatic/peripheral tissues and pancreactic B-cell dysfunction. Approximately 92% of patients with type 2 diabetes mellitus demonstrate insulin resistance, however hyperglycemia is always a consequence of insulin deficiency. This study was done on 120 patients newly diagnosed diabetes type 2 characterized by dyslipidemia that is increased triglycerides and decreased HDL. Hypoglycemia and weight gain are common problem with oral sulfonyl urea drugs. In this work three different oral hypoglycemic drugs repaglinide and glibenclamide (insulin secretagogues) and rosiglitazone (insulin sensitizer) were used for treatment of patients with type 2 diabetes mellitus. The effect of these drugs on fasting and postprandial blood glucose levels, lipid profiles, alanine aminotransferase and serum creatinine were studied.Three groups of newly diagnosed type 2 diabetic patients ,group 1 (40 patients) were subjected to treatment with repaglinide (2 mg three time daily) ,group 2(45 patients) were subjected to treatment with glibenclamide (5 mg once daily) ,group 3,(35 patients) were subjected to treatment with rosiglitazone (4 mg twice daily) . Fasting and postprandial blood glucose levels, lipid profiles (TC, TG, HDL and atherogenic index), alanine aminotransferase and serum creatinine were analyzed for these patients before and 4 and 8 weeks after oral hypoglycemic drug treatment. The same parameters were recorded for 40 normal individuals as control.The results demonstrated that repaglinide has a greater postprandial glucose regulator effect than glibenclamide and rosiglitazone. In addition the hypoglycemic episode and weight gain were less in patients treated with repaglinide than those treated with glibenclamide. Repaglinide produces greater percent reduction with respect to fasting blood glucose levels, postprandial blood glucose levels and atherogenic index compared to glibenclamide and rosiglitazone.

Key words: oral hypoglycemic, repaglinide, glibenclamide, rosiglitazone.

Authors: S. Manhal Falah , M. Abbas Husam
Published: March 2022

Anti-Neutrophil Cytoplasmic Antibodies (ANCA) are a heterogeneous group of autoantibodies with a broad spectrum of clinically associated diseases. The diagnostic value is established for Proteinase 3 (PR3)-ANCA as well as Myeloperoxidase (MPO)-ANCA. To estimate the frequency of anti-neutrophile cytoplasmic antibodies (ANCA) in sera from a group of Iraqi patients with some autoimmune diseases compared with a healthy control group. Serum samples were collected from one hundred patient, 47 males and 53 females; with age range of 16-70 years; 20 specimens from patients with systemic lupus erythematosus (SLE), 30 from patients with ulcerative colitis (UC), and 50 from patients with rheumatoid arthritis (RA). A group of 40 apparently healthy blood donors was included as controls. ANCA were checked using enzyme-linked immunosorbent assay (ELISA). Positive ANCA was detected in sera of 18 (18%) patients with autoimmune disorders. Anti-PR3 was detected in 6 (12%) patients with RA, and in 4(13.4%) patients with UC. Anti-MPO was detected in 3(6%) patients with RA and in 5(16.6%) patients with UC. All serum samples of patients with SLE showed negative ANCA. There were no ANCAs detected in sera from healthy individuals. Mean of serum anti-PR3 (U/ml) among the studied groups was 2.057 in RA, 2.209 in SLE, and 2.283 in UC, and 1.739 in control group. Statistical analysis revealed that differences in the anti-PR3 between RA, UC and controls were highly significant (P > 0.01), whereas just significant with SLE (P> 0.05). Mean of serum of anti-MPO (U/ml) among the studied groups was 0.711 in RA, 0.695 in SLE, and 1.170 in UC, and 0.652 in control group. Statistical analysis revealed that the differences in the anti-MPO between RA and SLE, controls were non significant (P < 0.05), whereas highly significance with UC (P> 0.01).It was concluded that ANCA markers might play a role in the inflammatory process and they are important factors for the clinical course, and prognosis in the patients with autoimmunity. However, ANCA in autoimmune disorders must be interpreted cautiously with particular attention paid to laboratory technique, the size, age and genetic background of the populations studied.

FREEDOM OF MISINFORMATION AND THE RELEVANCE OF CO-REGULATION IN MALAYSIA: A CROSS-JURISDICTIONAL ANALYSIS
Authors: Daud Mahyuddin
Published: March 2022

The spread of fake news on COVID-19 is causing public unrest and suspicion among citizens which is a challenge for countries facing the pandemic. The misinformation or disinformation which stems from uncertainties, unrest, and anxiety because of movement control order procedures, financial and economic hardship caused wrong information to spread like fire. Often referred to as ‘info-demic’, it becomes a second source of virulent information that requires arresting just like the pandemic itself. Controlling fake news in a pandemic is a daunting problem that slaps Internet regulation on its face. On the Internet, lies spread faster than the truth, and correcting this misinformation is a tonne of work. In this paper, we examine Internet self- and co-regulatory approaches in selected jurisdictions to reduce the impact of fake news on governments, industry, and private actors. Through a qualitative method and doctrinal content analysis, this article examines the various approaches adopted in arresting fake news. In the first section, we analysed specific legislation enacted by parliaments that criminalised the acts of disseminating and publishing fake news. In the second section, we found efforts to impose civil and criminal liability on platform providers to monitor online content. In the final section, we analysed self- and co-regulatory efforts to introduce online fact-checking portals and awareness campaigns. This research argues that the Internet self-regulation system in Malaysia is not bringing the desired result i.e., maintaining peace and security of the nation. Considering the impact of dangerous misinformation on society, more so in a global emergency like the present COVID-19 pandemic, it is submitted that co-regulation is more suitable if the social, moral, and cultural fabric of the society is to be maintained.
EVALUATION CHARACTERISTICS OF THE BAGASSE DRYING PROCESS

Published: March 2022

In the process of sugar production, much attention is paid to production automation, which controls the relevant technological parameters. Drying of pulp is an expensive and energy-intensive process. The use of only drying laboratory cabinets to control the moisture content of dry pulp is time consuming and can lead to deviations in the moisture content of the product. Installing humidity sensors as elements of the automation system at facilities with different temperature regimes at the inlet and outlet of the dryer is a simple and reliable way to save money, as it allows you to measure the humidity of dry pulp in the online stream, drying temperature and gas consumption. You can adjust the temperature, drying time, speed of movement of the product through the dryer and guarantee the required level of humidity of the product for granulation and storage. The case of dependence of pulp production on gas supply is considered. The input data is the gas flow rate over a fixed time t during which the specified output is produced. Build a graph of the frequency of distribution of each random variable, grouped into intervals. There are point estimates of this sample: mathematical expectation, standard deviation of each random variable to determine the optimal use of resources. To study the dependence of random variables, the parameters of the normal distribution law for these values ​​are determined. To effectively use the pulp drying process, the dependence on the amount of gas supply to the number of products is considered. According to the given normal law of distribution of technological parameters of drying and production of pulp at the corresponding given expenses of gas it is possible to put forward a hypothesis about an interval estimation of distribution between production and consumption of gas. With a stable gas supply of 0.108, the production of pulp will be optimal. The directions of further research of the sugar production process in order to develop current mathematical models and systems for its automation are determined.

Published: March 2022

The work is devoted to the development of a web-based support system for monitoring the implementation and management of small projects implemented according to the agile methodology (in particular, in the field of information technologies). Monitoring the implementation of projects is an important factor in their success, which in turn has a positive impact on the company's profits and the economy as a whole. Existing solutions in the field of project management were analyzed: the main models of project management were considered, as well as the main software tools for their implementation, their advantages and disadvantages. The task of developing a web-based system for monitoring and project management according to the Agile methodology was formed. The software tools for the system implementation were selected and the database structure was designed. The software of the server part was implemented using the architecture "model - view - controller", for which UML-diagrams of the relevant components of the system were developed. The developed server software uses a software interface with response to requests in JSON format, which allows you to further develop in addition to the web interface and mobile applications. The web interface implemented by the Angular framework implements basic functions for users and system administrators, such as entity management, authorization and registration, and includes an analytical tool for monitoring project performance, namely the burn-out chart. The developed software will be useful for small projects that use Agile methodologies, both partially and completely, and which do not require complex tools that require a long setup process. Implementing this system as a web-based application allows you to use it from both desktop computers and mobile devices.
SIMULATION OF QUASISTATATICS OF THE PROCESS OF FORMATION OF A LIQUID MENISK TYPE OF HANGING DROP ON THE SUBJECT OF METHODOLOGICAL PROVISION OF MEASUREMENT

Published: March 2022

A mathematical model has been developed for describing a capillary surface of the hanging drop type in the form of a system of fifth-order nonlinear differential equations, which corresponds to five geometric characteristics of the meniscus: the distance from the meniscus axis to a given point on the capillary surface, the distance from the plane normal to the meniscus surface at an umbilical point to a given point on capillary surface, the angle between the axis of symmetry and the normal to the capillary surface at a given point, the area and volume of the capillary surface bounded by a cut of the horizontal plane passing through a given point. By reducing the equation to a dimensionless form, it was possible to reduce to one setting parameter - the reduced Gaussian curvature at the umbilical point. The numerical solution of the obtained model with the subsequent reduction of the geometric and physical characteristics of the capillary surface to the radius of the capillary made it possible to simulate a quasi-static sequence of the meniscus surfaces. This made it possible to form a methodological basis for determining the static and dynamic surface characteristics of interfaces. Also, modeling the quasi-statics of meniscus formation made it possible to determine with high accuracy the values ​​of the characteristics of the meniscus in extreme cases, such as the moment of maximum pressure in the meniscus and the moment of separation from the end of the capillary. This is the methodological basis for such well-known methods for determining surface characteristics as the method of maximum pressure in the meniscus and the stalagmometric method. Also, if the obtained results are interpreted as a quasi-statics of changes in the parameters of a hanging drop of a solution of surfactants (hanging bubble) at a constant volume, it is possible to determine the dynamics of changes in surface tension. The numerical solution of the system of differential equations and the interpretation of the obtained tabulated results was carried out in the MathWorks MATLAB environment, which made it possible to form multilevel systematized data arrays of capillary surfaces, which can be basic for further interpretation, depending on the task at hand.

Published: March 2022

The paper presents the development of an approach to control the presence of inclusions inside steel pipelines of small, medium and large diameters by ultrasonic guided acoustic symmetric and antisymmetric modes of zero or first order. The approach created as a control system with distributed parameters. The distributed parameters of the control system are ultrasonic primary transducers and transmitters of the radio signal received by the primary transducers. Due to the peculiarities of the propagation of directional ultrasonic waves at a distance from several meters to tens of meters, one pair of primary transducers can control a significant part of the dangerous or potentially dangerous section of the pipeline. The dangerous section can be determined by geodetic measurements or by design documentation, such as air transitions or technological knees. The results of changing the propagation parameters of ultrasonic directional wave modes depending on the changes in the physical and mechanical parameters of the boundary to the walls of the pipelines are presented. It is found that symmetric and asymmetric modes react differently to changes in the environment, which allows to increase control accuracy and determining type of the environment (liquid or solid). The results are presented in the form of graphs and tables. The paper proposes to create a system based on a component approach, in order to unify parts of the system. It allows to realize the possibility of building it from parts of different manufacturers to increase its versatility and adaptation to the economic capabilities of the customer of such a control system. The components of the control system are the subsystems of primary ultrasonic transducers, information transmission and storage and processing. The paper presents an analysis of the transmission subsystem and proposes a wireless hierarchical structure taking into account the peculiarities of its operation at long distances and within settlements with a high level of radio signal noise. The data storage and processing component offered a software solution based on the Apache free license, which implements a file distribution system with high requirements for its data security and performance. The peculiarities of the proposed software solution, which allows the analysis of results using web technologies, have been analysed.

Published: March 2022

The article considers the issues of complications arising during the technological processes of drilling related to geological, geophysical and external conditions, urbanization and detection of inconsistencies between the actual drilling conditions from the projected ones due to changes in climate and geological changes, which occur in the period from the end of the project and the actual start of development of the field. The interrelation of the factors that complicate the drilling process with the stages of design and organization of precedents, on the basis of which the technological processes of drilling are modeled, is analyzed. The phases of the cycle of reasoning based on knowledge with a projection on the information cycle of drilling process control are revealed. The architecture of automation of technological processes of drilling with reference to the pyramid of computer-integrated production is presented. The article shows the possibility of applying machine learning methods to data analysis tasks related to the drilling process. The use of a combined approach to adapt the data used for knowledge-based decision-making is proposed. The problem of insufficient precedent for training knowledge-oriented system of intellectual support of decision-making processes is considered and the provision of full-scale simulators with the necessary amount of data for modeling complications of high-risk drilling process is substantiated. The authors determine the level of the expected ratio between the main objects of the knowledge-oriented system of intelligent decision-making on the course of the technological process: the problems of machine learning on the one hand and oil and gas wells on the other.
Late Paleozoic Yuma Arch, Colorado and Nebraska: Implications for Oil Exploration in Pennsylvanian Carbonate Reservoirs

Published: March 2022

The Yuma Arch is herein proposed as a major structural element forming the northeast margin of the Denver Basin. This previously little-recognized regional geological feature has significance in exploration for oil in this area of the basin. It was initially uplifted during the Paleozoic, but is largely masked by late Cretaceous - early Tertiary tectonic events. Limited pre-Cretaceous exploration drilling has not defined the precise location of the axis of the arch, but subsurface studies show that it occupies most of Yuma, Sedgwick and Phillips counties, Colorado, and Deuel County, Nebraska. The immediate west flank of the arch lies in parts of Washington and Logan counties, Colorado, and most significantly in Cheyenne County, Nebraska, where initial Paleozoic exploration has been focused around the discovery of Bird Oil Field in 1982, a small but unique, over-full, domal trap. Preservation of several cores from Pennsylvanian boreholes in Cheyenne County, Nebraska, facilitated study of cyclical Missourian-Virgilian carbonate reservoirs that provide significant future potential objectives for exploration on the underexplored arch. These cores also provided key biostratigraphic data that helped to clarify the correlation of classical Pennsylvanian strata. Studies of Paleozoic source rocks and migration pathways were conducted over the central and northeastern Denver Basin. These studies indicate that the immediate west flank and the crest of the Yuma Arch provide a significant regional catchment for oil in Paleozoic strata, and should be a target for future exploration. Processing and interpretation of aeromagnetic data provided a means to characterize the Precambrian crystalline core of the arch, and to define areas for seismic imaging of mobile basement block margins that appear to have initiated and sustained the growth of low-relief Paleozoic structural traps. This study reinforces the significant decoupling between pre-salt (Precambrian and Pennsylvanian) and post-salt (Cretaceous and Tertiary) geological processes in this area.
Post-Mississippian tectonic evolution of the Nemaha Tectonic Zone and Midcontinent Rift System, SE Nebraska and N Kansas
Authors: Burberry Caroline M. , Joeckel R. M. , Korus Jesse T.
Published: March 2022

The geologic structures of the central Midcontinent of the USA are largely buried and known only from geophysical datasets, coupled with sparse well control and limited outcrop. Such unconstrained geophysical models preclude a deeper assessment of possible continental interior seismic hazards, which have the potential to cause appreciable damage. Within the study area in southeastern Nebraska and northeastern Kansas is an area of elevated seismic risk, with a spatial relationship to the Nemaha Tectonic Zone and the Midcontinent Rift System. Using sequential restorations of three published cross sections within Nebraska and Kansas this study demonstrates that the Nemaha Tectonic Zone and Midcontinent Rift System have each been reactivated several times since the end of the Mississippian (the details of deformation prior to the Mississippian are not considered). Our reconstructions indicate that in addition to major Pennsylvanian-Early Permian fault reactivation during the Ancestral Rocky Mountain orogeny there was also deformation both prior to the post-Mississippian unconformity associated with uplift on the Nemaha Tectonic Zone and after the deposition of late Early-early Late Cretaceous sediments in the study area, potentially due to the Laramide orogeny. Results also indicate that the magnitude of the far-field stresses is sufficient to cause seismogenic reactivation on favorably oriented pre-existing faults. This history of reactivation of geologic structures in the central Midcontinent suggests that seismic hazards in the region in the present cannot be ruled out. Though dangerous large earthquakes are uncommon in the continental interior, seismic activity along the structures in the study area would threaten several large population centers and the potential for this activity should not be ignored.

OBJECTIVE

The objective of this study was to analyze the impact of medication intake on hemorrhage risk in patients with familial cerebral cavernous malformation (FCCM).

METHODS

The authors’ institutional database was screened for patients with FCCM who had been admitted to their department between 2003 and 2020. Patients with a complete magnetic resonance imaging (MRI) data set, evidence of multiple CCMs, clinical baseline characteristics, and follow-up (FU) examination were included in the study. The authors assessed the influence of medication intake on first or recurrent intracerebral hemorrhage (ICH) using univariate and multivariate logistic regression adjusted for age and sex. The longitudinal cumulative 5-year risk of hemorrhage was calculated by applying Kaplan-Meier and Cox regression analyses adjusted for age and sex.

RESULTS

Two hundred five patients with FCCMs were included in the study. Multivariate Cox regression analysis revealed ICH as a predictor for recurrent hemorrhage during the 5-year FU. The authors also noted a tendency toward a decreased association with ICH during FU in patients on statin medication (HR 0.22, 95% CI 0.03–1.68, p = 0.143), although the relationship was not statistically significant. No bleeding events were observed in patients on antithrombotic therapy. Kaplan-Meier analysis and log-rank test showed a tendency toward a low risk of ICH during FU in patients on antithrombotic therapy (p = 0.085), as well as those on statin therapy (p = 0.193). The cumulative 5-year risk of bleeding was 22.82% (95% CI 17.33%–29.38%) for the entire cohort, 31.41% (95% CI 23.26%–40.83%) for patients with a history of ICH, 26.54% (95% CI 11.13%–49.7%) for individuals on beta-blocker medication, 6.25% (95% CI 0.33%–32.29%) for patients on statin medication, and 0% (95% CI 0%–30.13%) for patients on antithrombotic medication.

CONCLUSIONS

ICH at diagnosis was identified as a risk factor for recurrent hemorrhage. Although the relationships were not statistically significant, statin and antithrombotic medication tended to be associated with decreased bleeding events.

Published: March 2022

La disputa ideológica surgida con la Guerra Fría implicó diversos mecanismos de propaganda político-ideológica por parte de los dos bandos en disputa. Aunque la Unión Soviética ya contaba con los partidos comunistas de cada país para la labor propagandística, decidió reforzar la disputa del “frente ideológico” por medio de la creación de instituciones cuyo objetivo fue ganar adeptos y simpatizantes entre intelectuales y artistas, sin que esto les implicara un compromiso militante. En México ésta labor se desarrolló por medio del Instituto de Intercambio Cultural Mexicano-Ruso. El presente artículo es una aproximación a su fundación, su funcionamiento, su vínculo político con el gobierno soviético, así como un recuento de los intelectuales participaron en los primeros años del Instituto.

The research made it possible to conclude that in 2020 the vector of support in Russia coincides with the directions of support in most countries, while in the past crises Russia has gone its own way. The authors justify, that applying a network approach to government anti-crisis programs may largely increase their success.
Das Element der Nicht-Identität im Antiziganismus
Authors: Freckmann Magdalena
Published: March 2022

Vor dem Hintergrund eines umstrittenen Verhältnisses von Antisemitismus und Rassismus sowie einer uneindeutigen Verortung von Antiziganismus in diesem Verhältnis untersucht dieser Beitrag Parallelen in der Struktur antisemitischer und antiziganistischer Bilder. Zentral ist dabei das von Klaus Holz in die Analyse des Antisemitismus eingebrachte Konzept der Nicht-Identität. Antisemitischen und antiziganistischen Bildern ist es gemeinsam, dass sie Individuen einem Kollektiv zuordnen und diesem vermeintlich wesenhafte Eigenschaften zuschreiben, um so Gegenbilder zum „Eigenen“ zu erschaffen; gemeinsam ist ihnen überdies die Vorstellung, die stigmatisierten Gruppen würden das „Wesen“ des „Eigenen“ durch „Vermischung“, durch das Uneindeutigwerden von Identitätskategorien bedrohen. Diese Vorstellung einer Nicht-Identität nimmt im antisemitischen und antizigantischen Fremdbild je unterschiedliche Gestalten an, indem sie sich mit den je charakteristischen Zuschreibungen verschränkt – mit Vorstellungen von Vormodernität und sozialer Devianz im Falle des Antiziganismus, mit solchen der Übermacht und Hypermodernität im Antisemitismus.

Sie haben einen wesentlichen Anteil an der Normalisierung extrem rechter Akteure und Positionen. Ziel ist es, durch erste theoretische Überlegungen und darauf aufbauende interdisziplinäre Analysen die Funktion des Livestreams zu untersuchen. Dieser Untersuchungsgegenstand stellt bisher eine Leerstelle in der Rechtsextremismusforschung dar. Es werden folgend Schnittstellen zur Medienwissenschaft aufgezeigt und der Livestream dort eingeordnet. Methodisch erfolgt zunächst eine theaterwissenschaftliche Beschreibung als theatrales Ereignis, gefolgt von einer korpuslinguistischen Analyse zur Funktion des dazugehörigen Chats. Diese ersten Analysen belegen, dass der Livestream eine eigenständige Protestform darstellt, die auf die Beziehungsebene abzielt. Der Artikel umreißt diese neuartige Protestform und bietet Anstöße zur weiteren interdisziplinären Diskussion.
Extrem rechte Influencer*innen auf Telegram: Normalisierungsstrategien in der Corona-Pandemie
Authors: Müller Pia
Published: March 2022

Dieser Beitrag untersucht normalisierende Strategien extrem rechter Influencer*innen in der Corona-Pandemie auf Telegram. Anlass hierfür ist die sogenannte Querdenken-Bewegung, die Milieus von Impfgegner*innen über Esoteriker*innen bis hin zur extremen Rechten vereint und sich maßgeblich auf Telegram informiert und organisiert. Im Digitalen und auf der Straße wird deutlich, dass sich in den Diskursen der Bewegung extrem rechtes Gedankengut etabliert und somit normalisiert. Stark rezipiert werden die Telegram- Kanäle Eva Herman Offiziell und Oliver Janich öffentlich. Aus Perspektive der Critical Discourse Studies untersuche ich, ob und inwiefern die beiden Akteur*innen Strategien zur Normalisierung extrem rechter Ideologien anwenden. Für den Zeitraum 01. 02. 2020–31. 01.2021 analysiere ich die thematische Schwerpunktsetzung mit einem Structured-Topic- Modeling-Verfahren und die assoziierten Posts im close reading. Mit „alternativer“ Informationsinterpretation knüpfen die Akteur*innen an gesamtgesellschaftliche Diskurse an. Verschwörungserzählungen und emotionalisierende Inhalte einen die Kanäle und ihre Follower*innen.

Background: In Alzheimer’s disease (AD), oscillatory activity of the human brain slows down. However, oscillatory slowing varies between individuals, particularly in prodromal AD. Cortical oscillatory changes have shown suboptimal accuracy as diagnostic markers. We speculated that focusing on the hippocampus might prove more successful, particularly using magnetoencephalography (MEG) for capturing subcortical oscillatory activity. Objective: We explored MEG-based detection of hippocampal oscillatory abnormalities in prodromal AD patients. Methods: We acquired resting-state MEG data of 18 AD dementia patients, 18 amyloid-β-positive amnestic mild cognitive impairment (MCI, prodromal AD) patients, and 18 amyloid-β-negative persons with subjective cognitive decline (SCD). Oscillatory activity in 78 cortical regions and both hippocampi was reconstructed using beamforming. Between-group and hippocampal-cortical differences in spectral power were assessed. Classification accuracy was explored using ROC curves. Results: The MCI group showed intermediate power values between SCD and AD, except for the alpha range, where it was higher than both (p < 0.05 and p < 0.001). The largest differences between MCI and SCD were in the theta band, with higher power in MCI (p < 0.01). The hippocampi showed several unique group differences, such as higher power in the higher alpha band in MCI compared to SCD (p < 0.05). Classification accuracy (MCI versus SCD) was best for absolute theta band power in the right hippocampus (AUC = 0.87). Conclusion: In this MEG study, we detected oscillatory abnormalities of the hippocampi in prodromal AD patients. Moreover, hippocampus-based classification performed better than cortex-based classification. We conclude that a focus on hippocampal MEG may improve early detection of AD-related neuronal dysfunction.
Properties of fuzzy Ito integrals with respect to fuzzy Brownian motion

Published: March 2022

Integral of a stochastic process with respect to Brownian motion is called Ito integral. Here the stochastic process and Brownian motion are random as well as fuzzy. Hence the Ito integral is fuzzy Ito integral. This paper deals with the properties of fuzzy Ito integral for simple adapted process with respect to fuzzy Brownian motion. The quadratic variance and covariance of FII are discussed. The concept of fuzzy simple adapted process, fuzzy martingale, fuzzy functions are used to derive the properties of fuzzy Ito integrals.

Restless Legs Symptoms and Periodic Leg Movements in Sleep Among Patients with Parkinson’s Disease
Authors: Bliwise Donald L. , Karroum Elias G. , Greer Sophia A. , Factor Stewart A. , Trotti Lynn Marie
Published: March 2022

Background: The association between restless legs syndrome (RLS) and Parkinson’s disease (PD) remains controversial, with epidemiologic and descriptive evidence suggesting some potential overlap while mechanistic/genetic studies suggesting relative independence of the conditions. Objective: To examine a known, objectively measured endophenotype for RLS, periodic leg movements (PLMS) in sleep, in patients with PD and relate that objective finding to restless legs symptoms. Methods: We performed polysomnography for one (n = 8) or two (n = 67) consecutive nights in 75 PD patients and examined the association of PLMS with restless legs symptoms. Results: We found no association between restless legs symptoms and PLMS in PD. Prevalence of both was similar to data reported previously in other PD samples. Conclusion: We interpret these results as suggesting that restless legs symptoms in PD patients may represent a different phenomenon and pathophysiology than RLS in the non-PD population.
Lack of association between gestational age adjusted TSH percentiles and neurodevelopmental outcomes among preterm infants

BACKGROUND: Limited evidence exists on whether subclinical hypothyroidism suggested by mildly elevated TSH levels affect neurodevelopment and growth in preterm infants. The objective of this study was to determine the association between gestational age adjusted TSH percentiles and neurodevelopmental outcomes among preterm infants. METHODS: Univariate linear regression analysis was conducted to determine, in infants born less than thirty-two weeks gestational age, the correlation between the TSH percentile on the last newborn screen and neurodevelopmental assessment scores and growth outcomes at eighteen to twenty-two months of corrected age. RESULTS: Seventy-four patients were enrolled in the study with a mean gestational age of 28.8 weeks. There was no correlation between the last TSH percentile value and Bayley-III cognitive composite score or other neurodevelopmental or growth outcomes. CONCLUSION: In a cohort of preterm infants, higher TSH percentiles suggesting potential subclinical hypothyroidism did not predict any adverse effect on neurodevelopmental or growth outcomes.

Optimum management of hip displacement in children with cerebral palsy (CP) is facilitated by an approach that focuses on anticipatory and preventive measures. Hip surveillance programs for children with CP were developed at the beginning of the new millennium, with the purpose of identifying hip displacement sufficiently early to permit a choice of effective management options. In the early years, hip surveillance was guided by epidemiological analysis of population-based studies of prevalence. In Australia, a National Hip Surveillance in CP Working Group was first convened in 2005. This resulted in a 2008 Consensus Statement of recommendations published and endorsed by Australasian Academy of Cerebral Palsy and Developmental Medicine (AusACPDM). The group undertook that the recommendations should be reviewed every 5 years to ensure currency and congruency with the emerging evidence base. As new evidence became available, hip surveillance guidelines developed, with the most recent 2020 Australian Hip Surveillance Guidelines endorsed by the AusACPDM. Implementing comprehensive hip surveillance programs has now been shown to improve the natural history of hip dislocations and improve quality of life. Standardised hip surveillance programs can also facilitate planning for multicentre research through harmonisation of data collection. This, in turn, can help with the identification of robust new evidence that is based on large cohort or population studies. Here a review of evidence informing the updated 2020 Hip Surveillance Guidelines is presented.
Operative treatment of the young cerebral palsy hip
Authors: Judd Hyrum , Hyman Joshua E.
Published: March 2022

Hip dysplasia, subluxation, and eventual hip dislocation are commonly encountered in the cerebral palsy population secondary to spasticity and loss of motor control, especially in those patients with more severe neurologic involvement. The treatment of hip disorders in these patients should take into account the degree of limb and hip involvement, pain severity, and overall functioning. Conservative management focuses on mitigating spasticity and preserving range of motion in order to provide an environment in which the femoral head remains concentrically reduced in the acetabulum. However, operative management, consisting of soft tissue or tendon releases, femoral or pelvic osteotomies, or hip salvage procedures, is sometimes necessary to treat the painful, subluxated, or dislocated hip. Radiographic hip surveillance in the pediatric cerebral palsy population is used to guide operative treatment. Long term hip containment is generally improved when surgical intervention is performed in the earlier stages of dysplasia. Younger patients who demonstrate progressive hip subluxation despite conservative measures may be carefully selected to undergo soft tissue procedures. Bony reconstruction, with adjunctive soft tissue procedures, is often necessary to better contain the proximal femur in patients above the age of four years.
