We analyzed 11 samples of wastewater, sludge and soil contaminated with acrylic acid nitrile, acrylamide and acrylic acid from the territory of Navoiyazot JSC (Navoi, Uzbekistan). As a result, 19 strains belonging to the bacteria of the genus Rhodococcus were isolated into a pure culture. In the process of selection, 2 strains of bacteria were selected that exhibit the highest amidase activity for acrylic acid (0.712 U / mg and 0.868 U / mg). Strains of Rhodococcus sp. - 8/4/1 and Rhodococcus sp. - 3/4/3 are potential amidase producers.
Reluctance against the machine: Retrieval of observational stimulus–response episodes in online settings emerges when interacting with a human, but not with a computer partner
Authors: Giesen Carina G. , Rothermund Klaus
Published: January 2022

Observing how another person responds to a stimulus creates stimulus–response (SR) episodes. These can be retrieved from memory on later occasions, which means that observed responses are utilized for regulating one’s own actions. Until now, evidence for storage and retrieval of observationally acquired SR episodes was limited to dyadic face-to-face interactions between two partners who respond in an alternating fashion. In two preregistered studies (total N = 252), we demonstrate for the first time that observational SR episodes can also be acquired in online interactions: Robust retrieval effects emerged when observers believe to be interacting with another person. In turn, retrieval effects were absent when observers believe to be interacting with a computer. Our findings show that feature-based binding and retrieval principles are pervasive and also apply to social interactions, even under purely virtual conditions. We discuss implications of our findings for different explanatory accounts of social modulations of automatic imitation.
Budget financing of educational services: current trends and prospects for improvement
Authors: LOBODINA Zoriana , BULAVYNETS Viktoriia , DANYLTSIV Khrystyna
Published: January 2022

Introduction. High-quality educational services play a key role in shaping the intellectual potential of the population, increasing the level of social well-being and ensuring inclusive sustainable development of the state. A prerequisite for the provision of high-quality and affordable public educational services is the proper level of their funding at the expense of various sources. The need to solve problems related to the budget financing of education, due to the limited volume and inefficient use of available financial resources, requires the development of new approaches to the organization of financing of educational services.
The purpose of the paper is to substantiate the theoretical and applied principles of budget financing of educational services and to develop recommendations for its improvement.
Results. The paper clarified the essence of educational services, systematized their classification features. The domestic practice of financing educational services from the State and Local Budgets of Ukraine has been described and analyzed.
Conclusions. The most justified is the definition of «educational service» as an intangible benefit, which is aimed at forming competences for the future professional and / or further educational activities. Educational services can be classified according to such criteria as the source of funding, forms, components and levels of education, ownership form and organizational and legal status of the educational entity. Review of budget financing of educational services through the prism of laws and categories of dialectics made it possible to form a scientific and methodological approach to its definition as an essence, phenomenon, content, form. Important ways to improve the budget financing of educational services are the optimization of the network and the costs of educational service providers of various levels; more efficient use of available funds; intensification of such forms of public participation at the level of territorial communities, regions as a public budget in the formation of budget resources for their further allocation to improve the conditions for the provision of educational services; formation of an offer of educational services for which budgetary resources are spent, providers, especially in the field of vocational and higher education, according to the results of monitoring the demand for graduates of certain specialties in the labor market; allocation of budgetary resources between budget programs in the field of providing educational services, taking into account gender aspects; strengthening control over the effective use of budgetary resources aimed at providing educational services.

Authors: KREMEN Olha , KULSHA Anastasiia , KREMEN Viktoriia
Published: January 2022

The public debt at the present stage is an objective economic phenomenon, a component of the financial system and a tool for implementing the economic strategy of the country, and its effective use can be a powerful factor in its economic growth. The paper is devoted to the study the economic essence, current state, structure and main trends of the total public debt of Ukraine. Essence of national debt, state-guaranteed debt, foreign and domestic debt and maintenance of relative amount and rate of debt are exposed.
Under the type of debt obligation, public debt is divided into direct (unconditional) and guaranteed (conditional) debt, which arises as a result of the state's obligations to third parties or guarantees for these obligations. There is also a division of public debt by type of creditor. Domestic and foreign public debt are distinguished on this basis. Based on statistical data of Ministry of finance of Ukraine and Government service of statistics of Ukraine the dynamics of the debt of Ukraine is analyzed and an analysis of its structure according the type of debt obligation, and the type of creditor is carried out.
Public and state-guaranteed debt during 2016–2020 grows on average annually by UAH 195.95 billion or 10.2 %.
The state external debt of Ukraine increased during the period under study from UAH 980.19 billion on 01.01.2016 to UAH 1258.52 billion. at the end of 2020 with a decrease in 2019 by UAH 168.54 billion.
The impact of external borrowing on economic growth is determined by the relative size of debt the share of public debt in GDP. The analysis of the indicator shows that in 2016–2020 it decreased from 81.0 % at the end of 2016 to 50.3 % in 2019, which corresponds to the legal norm, while in 2020 its share has already reached 60.8 %, which is 10.3 % more than in the previous year.

Published: January 2022

Oral Herpes is a viral infection caused by Herpes Simplex Virus. 80% of Oral Herpes is caused by HSV-1 which infects the skin and/or mucous membranes and produces painful sores or blisters on lips, gums, tongue, cheeks. The initial outbreak of virus strain can result in flulike symptoms, including fever, swollen lymph nodes and body aches. If not found in initial stages, it may result in systemic disorders like diabetes mellitus, cardiovascular or cerebrovascular diseases. The best solution to diagnose oral herpes is by analyzing Gingival Crevicular Fluid (GCF) through nested Polymerase Chain Reaction (PCR) technique. In periodontal disease pathogenesis, the inflammatory mediator levels present in gingival crevicular fluid represent relevant risk indicators for disease activity. Gingival crevicular fluid (GCF), a serum transudate or inflammatory exudate, can be collected from the gingival crevice surrounding the teeth. The fluid reflects the constituents of serum, the cellular response in the periodontium, and contributions from the gingival crevice. The amount of GCF is directly proportional to the severity of the inflammation. Now-a-days several methods for collection and estimation of GCF has been established. Hence, by analysing in this technique, the presence of HSV in the periodontium before the onset, at the time of periodontitis initiation, and periodically during its development can be diagnosed. KEYWORDS: Herpes virus, Gingival crevicular fluid, inflammation, periodontitis

Authors: Shobana Shekar , Amudhalakshmi Krishnan
Published: January 2022

Tooth size arch length discrepancies ideally require orthodontic treatment. But in certain exceptional cases like spacing due to aggressive periodontitis, pathological migration and non-compliance of the patient to undergo comprehensive orthodontic procedure, the scenario demands deviation from the routine treatment approaches and to customise the treatment plan based on the patient’s needs. This paper reports two cases: midline diastema in mandibular anteriors due to pathological migration managed with acrylic pontic retained by fiber reinforced composite restoration. The second case discusses anterior crowding managed conservatively by a fixed partial denture and the natural tooth pontic retained by fiber reinforced composite splint.

Published: January 2022

В статье приводится решение краевой задачи, моделирующей процессы синтеза 3D материала в условиях осевой симметрии. Разработан метод решения поставленной краевой задачи. Условие тонкостенности позволяет изучить конечные перемещения точек цилиндра при условии малых деформаций. Это, в частности, дает возможность решить задачу с точными краевыми условиями на движущейся поверхности. Обсуждаются особенности поведения основных характеристик, зависящие от давления на внутреннюю поверхность цилиндра, натяга на поверхности наращивания и скорости ее распространения. Получены распределения окружных и радиальных напряжений. Полученные результаты могут быть использованы при моделировании процессов синтеза тканых 3D материалов.

The article provides a solution to a boundary value problem that simulates the processes of synthesis of a 3D material under conditions of axial symmetry. A method for solving the stated boundary value problem has been developed. The condition of thin-walledness allows us to study the finite displacements of the cylinder points under the condition of small deformations. This, in particular, makes it possible to solve the problem with exact boundary conditions on a moving surface. The features of the behavior of the main characteristics, which depend on the pressure on the inner surface of the cylinder, the interference on the build-up surface, and the speed of its propagation, are discussed. The distributions of circumferential and radial stresses are obtained. The results obtained can be used in modeling the processes of synthesis of 3D woven materials.
Determination of the elastic-plastic state of a plane from an anisotropic material with an elliptical hole
Authors: Миронов Борис Гурьевич , Никитин Андрей Витальевич
Published: January 2022

Рассматривается упругопластическое положение плоскости из анизотропного материала, в котором имеется эллиптическое отверстие. Анизотропия - умение кристалла выражать разнообразные качества в разных направлениях. Присутствие данного качества в простейшем виде выражается только у монокристаллов. У поликристаллов анизотропия тела в основном (макроскопически) способна никак не выражаться из-за беспорядочной ориентировки микрокристаллов, или совершенно никак не проявляется, за исключением специальных случаев. При упорядоченном расположении химических частиц силы взаимодействия между ними и межатомные расстояния оказываются неодинаковыми, именно это и является причиной анизотропности кристаллов. Также это может быть и асимметрия его молекул. Неодинаковость макроскопически проявляется, лишь не симметричностью кристаллической структуры. Актуальность объясняется влиянием анизотропии на напряженно-деформированное состояние различных конструкций и тел.

The elastic-plastic position of a plane made of an anisotropic material in which there is an elliptical hole is considered. Anisotropy is the ability of a crystal to express various qualities in different di-rections. The presence of this quality in its simplest form is expressed only in single crystals. In polycrystals, the anisotropy of the body is mainly (macroscopically) capable of not being expressed in any way due to the disorderly orientation of microcrystals, or does not manifest itself at all, ex-cept in special cases. With an ordered arrangement of chemical particles, the interaction forces be-tween them and the interatomic distances are not the same, and this is the reason for the anisotropy of crystals. It may also be the asymmetry of its molecules. The disparity is macroscopically mani-fested, only not by the symmetry of the crystal structure. The activity is explained by the influence of anisotropy on the stress-strain state of various structures and bodies.

Published: January 2022

Рассмотрен вариант нелинейных определяющих соотношений для упругого ортотропного материала. Для описания зависимостей деформаций от напряжений второго и третьего порядков используется по 9 дополнительных параметров. Предложена система двумерных экспериментов на пластинчатых образцах, позволяющая определить все константы нелинейных моделей. Числовые значения параметров двух моделей найдены по известным экспериментальным данным. Сравнение результатов моделирования показывает, что модель третьего порядка более соответствует данным экспериментов, чем модель второго порядка.

A variant of nonlinear constitutive relations for an elastic orthotropic material is considered. To describe the dependences of deformations on stresses of the second and third orders, 9 additional parameters are used. A system of two-dimensional experiments on plate samples is proposed, which allows one to determine all the constants of nonlinear models. The numerical values of the parameters of the two models are found from the known experimental data. Comparison of the simulation results shows that the third-order model is more consistent with the experimental data than the second-order model.
Possibilities of vibration diagnostics of low-water bridge crossings
Authors: Локтев Алексей Алексеевич , Илларионова Лилия Алексеевна , Баракат Ахмад
Published: January 2022

Настоящее исследование посвящено изучению динамического поведения однопролетного низководного моста и оценке возможности детектирования появляющихся в процессе его эксплуатации дефектов. Актуальность работы подтверждается тем, что уровень воды для низководных мостов не позволяет провести визуальный осмотр и инструментальное обследование нижней части пролетного строения и ригельных балок опор. Поскольку для таких мостовых переходов не учитываются возможности пропуска ледохода, высоких вод и водного транспорта, то в вязкоупругую модель опирания пролетного строения вводятся обобщенные параметры вязкости и упругости, которые могут позволить учесть эти факторы. За расчетную схему принята балочная система, для описания деформирования которой могут быть применены уравнения для балки или пластины-полоски, которая может быть усилена дополнительной конструкцией для увеличения жесткости. В данной работе получены аналитические и графические зависимости для геометрических и динамических характеристик деформирования пролетного строения, с помощью которых можно выполнить оценку эксплуатационного состояния моста по собственным частотам колебаний пролетного строения.

The present investigation is devoted to the study of the dynamic behavior of a singlespan low-water bridge and the assessment of the possibility of detecting defects appearing during its operation. The relevance of the work is confirmed by the fact that the water level for low-water bridges does not allow for a visual inspection and instrumental examination of the lower part of the superstructure and the girder beams of the supports. Since such bridge crossings do not take into account the possibility of ice passage, high waters and water transport, generalized viscosity and elasticity parameters are introduced into the viscoelastic model of the superstructure support, which can allow these factors to be taken into account. A beam system has been adopted as the design scheme, to describe the deformation of which equations for a beam or a strip plate can be applied, which can be reinforced with an additional structure to increase rigidity. In this paper, analytical and graphical dependences are obtained for the geometric and dynamic characteristics of the deformation of the superstructure, with the help of which it is possible to assess the operational condition of the bridge by the natural frequencies of vibrations of the superstructure.

Joubert syndrome(JS), was first discovered by Marie Joubert, which is a rare autosomal recessive inherited disease belonging to ciliopathy with the causative mutation of genes. A 27-years-old woman was referred to our clinic for advanced research over the detection of fetal renal cyst.We observed policycstic kidney in detailed examination.INPP5E mutation was detected on chorion villus sampling.We were thought may be this findings will be associated with the syndrome, primarily joubert syndorme (JS),upon detection the vermis hypoplasia, policyctic kidney and molar teeth sign was observed on USG in the 23rd week of pregnancy.The vermis hypoplasia, posterior fossa expansion and bilateral polycystic kidney was seen on MRI and radiologist was reported as Dandy-Walker depend on this findings.They did not pay attention to the molar tooth finding.We were explanied prognosis and suggeted termination to the family.The family was accepted and fetus was terminated. The most common characteristic brain image of JS is the molar tooth sign(MTS) on the axial plane, cerebellar vermis (CV) hypoplasia, and a deepened interpeduncular fossa.The MTS is the key diagnostic feature for this disease. So far, more than 30 causative genes have been found for the various subtypes of JSRD.One of them is INPP5E. Defects of additional extra-nervous systems involve polycystic kidney disease, retinal degeneration, skeletal defects (such as polydactyly), and liver disorder.

Joubert Syndrome can be diagnosed in prenatally period.MTS can be seen easily with usg during prenatal period.The vermian hypoplasia and additional organ anomalies must be brought to mind JS and MTS should be searched.
Modeling Meteoroid Impacts on the Juno Spacecraft
Authors: Pokorný Petr , Szalay Jamey R. , Horányi Mihály , Kuchner Marc J.
Published: January 2022

Events which meet certain criteria from star-tracker images on board the Juno spacecraft have been proposed to be due to interplanetary dust particle impacts on its solar arrays. These events have been suggested to be caused by particles with diameters larger than 10 μm. Here, we compare the reported event rates to expected dust-impact rates using dynamical meteoroid models for the four most abundant meteoroid/dust populations in the inner solar system. We find that the dust-impact rates predicted by dynamical meteoroid models are not compatible with either the Juno observations in terms of the number of star-tracker events per day, or with the variations of dust flux on Juno’s solar panels with time and position in the solar system. For example, the rate of star-tracker events on Juno’s antisunward surfaces is the largest during a period in which Juno is expected to experience the peak impact fluxes on the opposite, sunward hemisphere. We also investigate the hypothesis of dust leaving the Martian Hill sphere originating either from the surface of Mars itself or from one of its moons. We do not find such a hypothetical source to be able to reproduce the star-tracker event-rate variations observed by Juno. We conclude that the star-tracker events observed by Juno are unlikely to be the result of instantaneous impacts from the zodiacal cloud.

Maputaland-Pondoland-Albany, one of the African biodiversity hotspots, is defined by a high diversity of its fauna and flora. Despite numerous studies published about the Lepidoptera of this region, our knowledge of diversity and distributional patterns of moths still remains inadequate. Our study evaluates the tussock moth richness and endemism of the wider Maputaland-Pondoland-Albany region. We describe for the first time the variety of the tussock moth fauna of Mozambique, with seven newly recorded genera (EuproctoidesBethune-Baker, 1911;HeteronygmiaHolland, 1893;LeucomaHübner, 1822;OgoaWalker, 1856;ParaproctisBethune-Baker, 1911;PolymonaWalker, 1855;TamsitaKiriakoff, 1954).

Published: January 2022

Effects of increased concentration of calcium chloride on growth and production of flavonoids in newly established shoot and callus Gypsophila glomerata cultures were studied. The highest impact of CaCl2 on the growth index was determined in callus cultures (GI = 0.92), while in shoot cultures calcium treatment reduced the amount of biomass (GI = 0.38). Total flavonoids in shoot cultures grown on MS medium and MS medium supplemented with double amount of CaCl2 were 0.36 mg/g d. w. In both callus cultures, 2 mg/g d. w. total flavonoids were quantified. Shoots and callus grown on non-modified media accumulated 0.02 mg/g d. w. quercetin derivatives. Unlike these, both shoots and callus grown on calcium-enriched media accumulated 0.03 and 0.05 mg/g d. w. of isorhamnetin derivatives. In vitro shoot cultures grown on MS medium enriched in twice the amount of CaCl2 accumulated the highest amount of saponarin (0.138 mg/mg d. w.).

Published: January 2022

In this paper, we propose a Dickey-Fuller difference statistic to sequentially detect the change-point that shift from an unit root process to a long-memory process. The limiting distribution of monitoring statistic under the unit root process null hypothesis as well as its consistency under the alternative hypothesis are proved. Simulations indicate that the new method can control the empirical size well even for the heavy-tailed unit root process when using the sieve bootstrap method computing its critical values. In particular, it performs significantly better than the available method in the literature under the alternative hypothesis. Finally, we illustrate the new monitoring procedure by a set of foreign exchange rate data.

Authors: Pavate Aruna Animish , Bansode Rajesh
Published: January 2022

Deep learning is a subspace of intelligence system learning that experienced prominent results in almost all the application domains. However, Deep Neural Network found to be susceptible to perturbed inputs such that the model generates output other than the expected one. By including insignificant perturbation to the input effectuate computer vision models to make an erroneous prediction. Though, it is still a dilemma whether humans are prone to comparable errors. In this paper, we focus on this issue by leveraging the latest practices that help to generate adversarial examples in computer vision applications by considering diverse identified parameters, unidentified parameters, and architectures. The analysis of the distinct techniques has been done by considering different common parameters. Adversarial examples are easily transferable while designing computer vision applications that control the condition of the classifications of labels. The finding highlights that some methods like Zoo and Deepfool achieved 100% success for the nontargeted attack but are application-specific.

Published: January 2022

This study aims to integrate perceived risk into elaboration likelihood model, develop a comprehensive research model to explain dual routes of persuasive communication through various factors affecting individual acceptance and usage of mobile shopping apps, and identify the antecedents of consumers’ perceived risk in the context of mobile shopping. Structural equation modeling is adopted to test the proposed model. Information quality has a negative effect on perceived risk (central route), while source credibility has a positive impact on perceived usefulness (peripheral route). The antecedents of perceived risk including information quality, source credibility, familiarity, and personal innovativeness which are divided into four categories: cognition-based, affect-based, experience-based, and personality-oriented. The four antecedents significantly affect consumer’s perceived risk in adopting mobile shopping apps. The results show that consumers’ perceived usefulness and perceived risk affect consumers’ behavioral intentions of mobile shopping apps adoption.

The development of platinum-free counter electrodes (CEs) is significant in the development of cost-effective dye-sensitized solar cells (DSSCs). In this study, Pt-free, low-cost carbon black-titanium nitrate (CB-TiN) nanocomposite counter electrodes CEs were prepared via simple heating and cooling process for application in DSSCs. Different weight concentrations of CB-TiN (15-200 mg) were uniformly blended with PEDOT:PSS at 350 rpm and 150°C for 10 mins. Thereafter, the solution mixtures were immediately cooled at 4°C overnight to produce PEDOT:PSS/CB-TiN CEs. Further, to investigate the effects of iso-octyphenoxy-polyethoxyethanol (TX100) on the performance of the PEDOT:PSS/CB-TIN CE, various concentrations of TX100 (1-10%) were blended with PEDOT:PSS/15mgCB-TiN CE mixture at room temperature to produce PEDOT:PSS/15mgCB-TiN/TX100 CEs. The results indicated a gradual increase in electrocatalytic activity coupled with a reduction in internal resistance in the DSSCs as the weight of CB-TiN nanoparticles was enhanced. Similar results were obtained when the concentration of TX100 was increased. The DSSCs with the PEDOT:PSS/200mgCB-TiN and PEDOT:PSS/15mgCB-TiN/10%TX100 CEs exhibited optimum performances of 4.42% and 4.32%, respectively. Their performance closely matches that of the Pt CE (4.43%).

The experimental investigation on the compressive properties of honeycomb sandwich composite panels was carried out in this paper. The local compressive specimens and global compressive specimens were manufactured for compressive experiment. The test fixture has been designed and manufactured to examine the compressive behavior of honeycomb sandwich panel. The results indicate that there is no buckling occurred in local compressive specimen skin during the whole compressive experiment. The average failure load of local compressive specimens is 106884 N. The local buckling increases with the loading until the global compressive specimens are unstable. The fracture positions locate along the horizontal line at the middle height of global compressive specimen, which is different from local compressive specimens. The average buckling load and failure load of global compressive specimen are 31850 N and 82282 N respectively.

Authors: Fukui Kaito , Tsukamoto Hideaki
Published: January 2022

Functionally graded materials (FGMs) are multi-phase composites to be engineered with gradual spatial variations of constituents. Centrifugal techniques enable to have a continuous gradient manner in FGMs. In this study, zirconia (ZrO2)/ 304 stainless steel (SUS304) FGMs were fabricated using centrifugal slurry methods with powders of ZrO2 and SUS304 mixed with a dispersant, ammonium polycarboxylic acid (PCA). The green body samples produced by centrifugal techniques were consolidated using spark plasma sintering (SPS). The fabricated samples were investigated on their microstructures and contents using scanning electron microscope (SEM) with EDX and micro Vickers and nanoindentation hardness. The results demonstrated that controlling of the continuous gradient were possibly achieved using the combination of the current techniques.

Published: January 2022

Strontium titanate SrTiO3 thin films have been fabricated by radio frequency magnetron sputtering on P-type Si at substrate temperature of 200°C. Two different postdeposition annealing methods were applied on the sputtered films. Specifically, conventional thermal annealing at 300°C for 60 min and photoactivation treatment under deep ultraviolet-ozone for 30 min. The dielectric properties of the SrTiO3 thin films were investigated by fabricating Au/STO/p-Si MOS capacitors. A dielectric constant (κ) with a value of 13 was obtained for as-deposited film, which has a thickness of 107 nm. While post-annealed samples showed elevated values of κ, precisely, 15.33 and 19.32 for films exposed to deep ultraviolet-ozone photoactivation and films annealed at 300°C, respectively. All devices showed a leakage current in the order of 10-8 A/cm2 at 1V. Based on XPS analysis, photo-activated films revealed the lowest percentage of oxygen vacancies, which designates the capability of this technique to enhancing films quality at a lower temperature.
Study on the Growth Mechanism of Chlorocarbon Radicals on the Surface of CVD Diamond (100)
Authors: Jian Xiao Gang , Hu Ji Bo
Published: January 2022

In the CH3Cl/H2 atmosphere, the adsorption process of various active chlorocarbon groups (CH2Cl, CHCl, CCl) and CH3 on the surface of clean diamond used density functional theory (DFT) calculations during CVD process. The reaction heat and activation energy of the active sites on the adsorption reconstituted surface of D-CH3 and D-CH2Cl were calculated by transition state search to explore the actual effect of the carbon chloride active group on the surface of CVD diamond (100).The results showed that the adsorption capacity of CHCl, CH2Cl and CCl on the substrate was gradually weakened and the adsorption energy of CH2Cl and CH3 was close. Both CHCl and CH2Cl could form diamond bonds with the substrate carbon atoms to directly promote the growth of the diamond coating. Since the C-Cl bond was weaker than the C-H bond, the adsorption recombination surface of CH2Cl generated an energy barrier of the active site lower than the adsorption reconstitution surface of CH3. Therefore, using CH3Cl/H2 as a gas source could effectively reduce the energy required for diamond coating growth.

Iron (III) trifluoromethanesulfonate [Fe (OTF)3] has been proven to be an effective catalyst in the synthesis of 2-phenylquinoline-4-carboxylic acid by the Doebner reaction using one-pot pyruvic acid, aniline, and benzaldehyde. This method shows attractive characteristics including concise one-pot conditions, high atom economy, very limited energy consumption, and the sequential catalytic process requires only a catalytic (15 mol%) amount of Fe (OTf)3 with short reaction periods (3 h) . Meanwhile, the catalyst was easily recovered from the reaction system and reused smoothly with only a little loss of activity.
Juxtacortical chondromyxoid fibroma in the small bones: two cases with unusual location and a literature review
Authors: Oh Sun-Ju , Chung So Hak
Published: January 2022

Chondromyxoid fibroma is a rare bone tumor of cartilaginous origin, representing less than 1% of all bone tumors. It preferentially arises in the eccentric location of the metaphysis of a long tubular bone. Juxtacortical locations are reported infrequently in the long bones and even more rarely in short tubular bones, with only three cases documented. Here we present two new cases of juxtacortical chondromyxoid fibroma in the small bones. One was an intracortical osteolytic lesion of the metatarsal bone of the foot with degenerative atypia that histologically should be differentiated from chondrosarcoma. The other was a phalangeal mass protruding into the interphalangeal joint of the hand, which had been labeled mistakenly as a soft tissue mass preoperatively. These cases illustrated that chondromyxoid fibromas have various the manifestations and should be included in the differential diagnosis of an osteolytic lesion or an exophytic mass in the small bones.

OBJECTIVES: Elder abuse has significant adverse consequences for the overall health and well-being of the elderly, including premature mortality. Using cross-sectional data, we assessed the prevalence of elder abuse in India, its variation across states, and associated factors.METHODS: Nationally representative data from the first wave of the Longitudinal Aging Study in India were analyzed. Bivariate and multivariate analyses were used to study the prevalence, state variations, and associated factors of elder abuse.RESULTS: Overall, 5.2% of elderly adults (≥60 years) had experienced abuse in the year prior to the survey and 3% had experienced abuse within their own household. Verbal abuse or disrespect was the most common form of abuse. Considerable variation was observed in the prevalence of elder abuse across states and union territories, with the highest prevalence observed in Bihar (11.6%) and Karnataka (10.1%). In regression analysis, education level emerged as a protective factor against elder abuse, particularly among women. Older adults who lived alone, had functional limitations, had multiple morbidities, and had been hospitalized in the past year were more likely to experience abuse. Older adults who experienced abuse were 2 times more likely to experience depressive symptoms.CONCLUSIONS: Cross-state variation in the prevalence of elder abuse and subgroup differences suggest that state-specific interventions and essential monitoring of older adults with functional limitations, chronic diseases, and recent hospitalization can further reduce the prevalence and consequences of elder abuse in India.
