CLINICAL AND EPIDEMIOLOGICAL PROFILE OF CHILDREN WITH MEGALOBLASTIC ANEMIA AT A TERTIARY CARE HOSPITAL IN WESTERN INDIA: A CROSS SECTIONAL STUDY
Authors: Sharma Anjali , Deshpande Anand , Sauparna Chhavi , Ahmed Zeeshan
Published: April 2021

Background: In India most cases of Megaloblastic anemia are caused by nutritional deciency of
vitamin B12 and Folic acid. Initial workup include Complete Blood Count(CBC), Peripheral blood
smear(PBS) ,Vitamin B12 asssay, folic acid assay and Bone marrow if required. Therefore, this study is planned to study the
clinical and laboratory prole of children with Megaloblastic anemia and to study the clinical outcome of children with
Megaloblastic anemia
Methods: The study was a prospective observational study conducted among 60 children with megaloblastic anemia, aged 1-
12 years. Demographic data, clinical symptoms and signs, laboratory ndings, serum B12 and Folic acid ,Bone marrow report
and stool routine microscopy report were collected. Chi square test was applied.
Results: Among the 60 children 40% were female sand 60% were males. The age of the study population ranged from a
minimum of 1 month to a maximum of 12 years with a mean(SD) of 8.08 (± 5.45).Majority of children (41.6%) were in age group
of 6 months- 1 year. Most common symptoms fever and most common sign is pallor. More than fty percent cases presented with
severe anemia. Many cases reported late, leading to delay in diagnosis leads to poor outcome. Developmental delay
(neurological manifestation) is strongly associated with vitamin B 12 deciency as compared to folic acid deciency. (p value
<0.05)
Conclusions: There is a slight female preponderance seen in megaloblastic anemia, probably due to reduced attention to girl
children in the study group. neurological manifestation is strongly associated with vitamin B 12 deciency as compared to folic
acid deciency.

Hand, foot, and mouth disease is a very infective infection. It's caused by viruses from the Enterovirus genus, among the Enterovirus genus coxsackievirus is most commonly found associated with Hand , Foot and Mouth disease. Hand, foot and mouth disease (HFMD) causes rashes or vesicular lesions in the affected individuals and lesions are found in extremities and upper extremity lesion is more common along with feet and mouth. It is mostly seen in school going children, and causative agents are likely Enterovirus-A (EV-A) species, including Coxsackievirus-A16 (CV-A16) and Enterovirus-71 (EV-71) [1]. Hand , Foot and Mouth Disease is usullay mild and selimiting. In the affected patient's rst identied by a brief prodromal fever, followed by pharyngitis, mouth ulcers and rash on the hands and feet. The disease is caused by numerous members of the Enterovirus genus of the family Picornaviridae e.g. Coxsackievirus type A (CA) and Enterovirus 71 (EV71), and the clinical features are not identiable and distinguishable from virus to virus. [2] . Young children have the highest risk of getting hand, foot, and mouth disease. Risk increases if they attend daycare or school, as viruses can spread quickly in these facilities. Children usually build up immunity to the disease after being exposed to the viruses that cause it. This is why the condition rarely affects people over age 10. However, it's still possible for older children and adults to get the infection, especially if they have weakened immune systems. EV71 is a human enterovirus A species causing infection in clildren[3,4] . Clinically though it is mild symptoms and self limiting initially, such as a fever along with unraised colorless spots, and bumps on the hands, feet, and mouth. In some patients with severe disease several neurological complications (including cephalomeningitis, encephalitis, and neurogenic pneumonedema) and circulatory disorders. Occasionally, it even causes death [5]. Therefore, an early indicator of EV71 infection with neurological involvement is crucial for appropriate management [6]. Hand, foot, and mouth disease by enterovirus infection repots severe complications (such as brain stem encephalitis, neurogenic pulmonary edema, and other fatal complications) and a high mortality due to HFMD are more frequently related to EV71 infection[7,8] .

INTRODUCTION: The appendix, another named vermiform appendix (from the Latin ward-appendix
means “dangling” + “vermis”+ “form” i.e.-dangling worm-shaped thing) is a diverticulum of caecum
and marks the beginning of the colon in the conuence of taenias. The appendix is posteromedially attached to the caecum,
about 2cm below the ileocecal junction. Taking into account that often the appendix is a mobile structure, the medical
9 importance of its relative position has been questioned by some authors. In general, however some authors describe a
signicant relationship between its location and sign and symptoms of acute appendicitis.
OBJECTIVES:1.To study the commonest position of appendix seen intraoperatively among the patients with acute appendicitis
present in Emergency and OPD of Burdwan Medical College.
2.To identify the commonest position responsible for of gangrenous appendix and appendicular perforation.
3.To identify various signs and symptoms according to their different anatomical position and correlation with intraoperative
ndings
MATERIALS AND METHODS: This is a Prospective Observational Study in Burdwan Medical college and hospital ,May 2019 to
July 2020 on 100 patients. All willing patients in Emergency and OPD of BMCH with acute and recurrent appendicitis who
underwent surgery are included in this study.
RESULTS: rd th Appendicitis is commonest during 3 decade (43%) followed by 4 decade (36%).Appendicitis is slightly commoner
in females with male: female ratio 1:2.4..The most common position of appendix in our study is pelvic position.

Published: April 2021

The prevalence of Vitamin D deciency in India ranges from 50% to 94% in different age groups. Primary
objective of the study was to determine the prevalence of vitamin D deciency among adults with nonspecic complaints of musculoskeletal pain/tiredness/weakness with no other symptoms or medical comorbidities. The normal
reference range of our laboratory for serum 25(OH)D level is 30–100 ng/ml. Out of the entire cohort of 400 patients, only 12%
(n=48) had sufcient serum vitamin D levels (>30 ng/mL) .T he mean± S.D. value of serum vitamin D for the study population
was 20.61 ±11.67 (median =20; range= 2.4-124). More than half of the study sample (n=222; 55.5%) analyzed had decient
serum Vit D levels (≤20 ng/ml) and almost a third of the sample (n=130; 32.5%) had insufcient serum Vit D levels (21-30 ng/ml).
This study also documented statistically signicant results between serum vitamin D levels in patients with different sunlight
exposure (p=0.032). This study conrms a high prevalence of vitamin D deciency in people with diffuse musculoskeletal pain
in apparently healthy urban Indians and advocates the supplementation of vitamin D in such patient population.

Authors: Kumar K.Prasanth , Lavanya A.D.V. , Reddy P.Surendra
Published: April 2021

Mesenteric cysts are rare and occur in patients of any age. They are asymptomatic and found incidentally
or during the management of their complications. They commonly originate from the small bowel
mesentery, although a proportion of them have been found to originate from the mesocolon (24%) and the retroperitoneum
[1] [2,3,4,5] (14.5%). A mesenteric cyst originating in the sigmoid mesocolon is a very rare nding. They are a rare cause of abdominal
pain and are discovered incidentally. If symptomatic, patients with these cysts present with abdominal pain, vomiting and low
backache. Performing a thorough physical examination and conducting radiological investigations like ultrasonography
(USG), computed tomography (CT) are keys in diagnosing the mesenteric cysts.

Main Difficulties Faced by EFL Students in Language Learning
Authors: Alsalihi Hanan Dhia
Published: April 2021

Many undergraduate learners at English departments who study English as a foreign language are unable to speak and use language correctly in their post -graduate careers.  This problem can be attributed to certain difficulties, which they faced throughout their education years that hinder their endeavors to learn. Therefore, this study aims to discover the main difficulties faced by EFL students in language learning and test the difficulty variable according to gender and college variables then find suitable solutions for enhancing learning.  A questionnaire with 15 items and 5 scales were used to help in discovering the difficulties. The questionnaire was distributed to the selected sample of study which consists of 90 (male and female) students selected randomly from the 3rd and 4th year class levels at English departments from colleges of Languages and Education (Ibn-Rushd) at the University of Baghdad. The results of the study showed that EFL students face difficulties in language learning such as the role of society in discouraging English language learning, the learners’ shyness, which prevents them from speaking English in fear of making mistakes, lack of motivation, and the influence of class size and crowdedness. After analyzing the results, some recommendations and suggestions were presented to solve the problem and eliminate difficulties.
Microangiopatías trombóticas primarias: una revisión narrativa
Authors: Henao-Piedrahita Natalia
Published: April 2021

La microangiopatía trombótica (MAT) es un síndrome donde hay formación de microtrombos en la circulación que llevan a anemia hemolítica microangiopática (AHMA) y trombocitopenia con falla multiorgánica, debido a la isquemia de los tejidos. Las MAT pueden ser primarias sin causa subyacente asociada, como la púrpura trombocitopénica trombótica debida a deficiencia de la enzima ADAMTS13, el síndrome hemolítico urémico debido a la toxina Shiga de Escherichia coli enterohemorrágica, y la MAT producida por alteraciones en la regulación del complemento. Adicionalmente, pueden ser secundarias a enfermedades malignas, infecciosas, metabólicas, autoinmunes o inducidas por el embarazo. Estas patologías requieren diagnóstico y tratamiento oportunos debido a que tienen alta morbimortalidad y se asocian a complicaciones que incluyen enfermedad renal, alteraciones neurológicas como convulsiones, accidente cerebrovascular, coma y muerte. El tratamiento es multidisciplinario y se enfoca en el soporte hemodinámico, transfusional y en el manejo de la etiología cuando esta es identificada. La siguiente revisión pretende explicar de forma clara y precisa los aspectos generales de las MAT primarias.

Authors: Bonilla-Sepúlveda Óscar Alejandro
Published: April 2021

Introducción. El cáncer de mama es el cáncer que más afecta a las mujeres. Se estima que 1 en 8 mujeres desarrollarán cáncer de mama eventualmente. Una de las herramientas contra el cáncer de mama es crear estrategias de detección temprana de la enfermedad, y la mamografía ha demostrado ser de mucha utilidad. El objetivo del estudio fue determinar la frecuencia de la mamografía, ecografía, examen clínico y autoexamen mamario, y evaluar su uso como pruebas de tamización para cáncer de mama en una cohorte de pacientes atendidas en la Clínica del Prado en Medellín, Colombia. Metodología. Estudio descriptivo, transversal, efectuado a través de encuesta en 318 usuarias atendidas entre junio y diciembre de 2018. Se estimó la frecuencia de los diferentes métodos de tamización y se evaluaron las características sociodemográficas, antecedentes personales y antecedentes familiares. Adicionalmente, se buscó si había asociación significativa entre la práctica de la mamografía como prueba de tamización y las variables de estudio. Resultados. La media de la edad fue de 44,2 años. El método de tamización más usado fue el autoexamen (70,1%), en su mayoría mensual (76,7%), seguido por la mamografía (56%), en su mayoría ocasional (46%). El examen clínico de mama (ECM) se utilizó en el 45,9% de las pacientes, con una frecuencia anual en el 50% de ellas. Por último, la ecografía de mama se practicó en el 43,1% de las encuestadas, con una frecuencia en su mayoría ocasional (39,4%). Se realizó un análisis independiente para mujeres entre los 50 y 69 años, y aunque el 93,8% se habían realizado la mamografía, solo el 9,3% lo hizo bienal, como lo recomienda el Ministerio de Salud y Protección Social. No se hallaron diferencias estadísticamente significativas entre las variables de estudio y la realización de la mamografía como método de tamización. Conclusión. En la población estudiada, el autoexamen de mama es realizado por la mayoría de las mujeres con una frecuencia mensual. La frecuencia de la mamografía, el ECM y la ecografía de mama fue muy similar, y se esperaba encontrar un mayor porcentaje de mamografías realizadas como prueba de tamización. Se requiere fortalecer esta estrategia efectiva para la detección temprana de cáncer de mama, teniendo en consideración la situación particular de cada paciente, la efectividad y beneficio de la técnica, así como los costos asociados.

Authors: Palacios-Ramírez Dabely A. , Varela-Aguirre Gabriel Jaime
Published: April 2021

El cáncer es una causa importante de morbilidad y mortalidad en los receptores de trasplante. La combinación de infecciones virales, terapia de inmunosupresión y la alteración en el sistema inmune en los pacientes trasplantados, contribuyen al desarrollo de cáncer. El sarcoma de Kaposi es causado por el virus herpes humano 8 (VHH-8), y aunque es raro en la población general, puede ser hasta 300 veces más frecuente en los pacientes con trasplante renal. El diagnóstico de la enfermedad se realiza a menudo con base en las características de las lesiones, pero debe ser confirmado por histología. En años recientes, los inhibidores de mTOR han mostrado ser efectivos para el control del sarcoma de Kaposi en los pacientes trasplantados, ya que se interrumpe el efecto antiapoptótico y la angiogénesis dependientes de la proteína mTOR, los cuales son esenciales para el desarrollo y la propagación de células malignas. Se presentan dos casos de pacientes con sarcoma de Kaposi ganglionar, sin lesiones en piel, en nuestro centro de trasplante, quienes respondieron de manera positiva al cambio del esquema inmunosupresor con inhibidores de mTOR.

Published: April 2021

The task for determining of the maximum pressing force at given displacement with acceptable accuracy is urgent in the process of the car axial joint designing. Friction at the interface between the contacting surfaces of the matrix and the body of the axial joint has significant effect on this technological parameter. Modeling of the surfaces contact interaction without taking into account the action of the friction force can lead to high error in the result. The parameters of the Coulomb friction model without carrying out large amount of experimental work using the finite element method is proposed to determine to improve in the accuracy of the maximum pressing force obtained as result of modeling.

Wh-P and the Intervention Effect of negation
Authors: Wang Aiqing
Published: April 2021

Following the Government and Binding theory mainly developed by Chomsky (1981, 1982, 1986), I explore wh-P and the Intervention Effect of negation in Late Archaic Chinese (LAC). I propose that the inverted order of wh-P in LAC is generated via PP inversion followed by the separate preposing of wh and P. The wh-complement raises to [Spec, PP] and further moves to the specifier position of a functional projection. If the wh-PP is base-generated preverbally, the preposition moves to the head position of the functional projection directly; if the wh-PP is base-generated postverbally, the preposition must first incorporate to a V0 and then move to the head position of the functional projection through excorporation. In terms of the Intervention Effect, wh-arguments and adverbials that usually move to the Low focus position below negation are subject to a blocking effect caused by negation, so these wh-phrases have to land in the High focus position above negation which is expected to accommodate ‘high’ adverbials exclusively. I argue that the Intervention Effect in LAC is a consequence of Q-binding as feature movement of [wh], interacting with fronting into the hierarchy of clause-internal positions driven by [Focus] feature.

A stable composition (against crystallization) of germanate glass doped with Yb3+ for mid-infrared laser applications is presented. Broad emission spectrum of Yb3+ was obtained for the fabricated glass. Laser operation was demonstrated in 13 mm long waveguide written in the glass using a femtosecond laser operating at 524 nm center wavelength sending 250 fs ultrashort pulses. The resulting CW laser operated at 1.04 µm in the fundamental mode of the waveguide. The propagation loss through the waveguide was 0.6 dB/cm at 1550 nm for 45 µm diameter of the modified structure. The mode analysis of the developed waveguide structure is also presented in COMSOL Multiphysics to study the electric field distribution through different modes of propagation in the waveguide and the confinement loss associated to them.

We present a novel encryption method for multiple images in a discrete multiple-parameter fractional Fourier transform scheme, using complex encoding, theta modulation and spectral fusion. All pairs of original images are encoded separately into a complex signal. The spectrum of each complex signal can then be scattered into various positions in the spectral plane and multiplexed into one spectral image with a combination of theta modulation and spectral fusion. After Fourier transforming back to the spatial domain, the multiplexed signal is encrypted in the discrete multiple-parameter fractional Fourier transform domain. Information about the original images can only be successfully decrypted given the possession of all correct keys. The parameters of chaotic pixel scrambling for the proposed method enlarge the key space. Moreover, the proposed method solves the crosstalk problem of multiple images and improves the multiplexing capacity. Numerical simulations demonstrate the effectiveness of the proposed method.

Recently it has been found that the heterostructures of n-ZnO/p-Si are promising photovoltaic alternatives to silicon homojunctions. It is well known that the energy band diagram of a heterostructure is crucial for the understanding of its operation. This paper analyzes the ZnO/p-Si heterostructure band by using free AMPS-1D computer program simulations. The obtained numerical results are compared with theoretical calculations based on the depletion region approximation model and the Poisson’s equation for electric potential. The results of the simulation are also compared with the experimental C-V characteristics of the test n-ZnO/p-Si heterostructure. The simulated C-V characteristics is qualitatively consistent with the experimental C-V curve, which confirms the correctness of the determined band diagram of the n-ZnO/p-Si heterostructure.

Authors: BUKANOV Hryhorii
Published: April 2021

The article highlights the main approaches and their potential in the formation and implementation of project-oriented policy of environmental development of the regions of Ukraine. It is proved that ensuring sustainable balanced regional development in Ukraine is one of the most important prerequisites for its sustainable (balanced) economic growth in social, economic and environmental aspects, and the management of environmental development of the region is implemented through the formation and implementation of both the strategy of state (national) policy and regional environmental policy. Sustainable or balanced development of regions involves the development of all its components, and especially — environmental. Greening of state and regional development is a natural process of further improvement of economic relations and the achieved level of development of productive forces, based on ecologically oriented innovation policy of the state and regions to ensure environmental security of the state and its territories. It is determined that the regional ecological policy acts as a component of the national ecological policy, which is based on the ecological national and international legislation, standards and norms and contributes to the sustainable development of the region as a socio-ecological and economic system. The basis of regional environmental policy are the following principles: priorities of national interests; legislative provision of rights and powers of regional policy subjects; taking into account the peculiarities of the regions; partnership, which provides for the need to establish cooperation between public authorities at all levels and local self-government and to ensure political stability and social harmony in the implementation of national policy. The managerial possibilities of such approaches to the formation of project-oriented policy of ecological development of regions as project management (project management), marketing of territories or ecological marketing in the context of sustainable development of regions, benchmarking in ecological development are singled out and defined regions as strengthening the competitiveness of the region, a cluster approach in the ecological development of regions. An environmental project (or a project in the field of environmental protection) means a complex system of interconnected structured tasks and measures for environmental protection, which have a stage-by-stage nature of implementation aimed at solving the problems of ecological development of the region.

The article analyzes the state of professionalization of public service personnel. It is determined that professional training of civil servants, able and ready to effectively solve the whole set of managerial tasks in the context of public administration reform in modern Ukraine, constantly increase their managerial potential and practical experience in a dynamically modernizing society is an urgent problem of public management science. Managerial culture is part of the structure of professional culture of civil servants and its actual functioning determines the art of management. According to the results of the analysis of professional activity of civil servants, currently in Ukraine there is a tendency to increase the number of managers who are insufficiently prepared for management activities, who have not formed a high level (so-called «patchwork») managerial culture. At the same time, a modern effective civil servant in the conditions of dynamic changes in many spheres of public life is a specialist focused on modern management priorities, who has the latest management technologies, capable of professional self-actualization and continuous improvement. The formation of a politically neutral, professional, honest, sensitive to the demands of citizens employee, as well as public managers with modern management knowledge, developed innovative worldview, able to act in conditions of uncertainty, is an important task. Socio-psychological factors of managerial activity related to taking into account the individual psychological characteristics of people and patterns of communication in social groups need to be taken into account. The development of a modern culture of governance and responsibility of managers at all levels for human resource management, strengthening the moral and spiritual capital of managers in the context of implementing new principles of civil service is impossible without solving the problem of developing managerial culture of civil servants. Effective development of creative self-realization of a civil servant’s personality is possible when it is provided with a solid legal basis and is carried out on the appropriate scientific basis. The generalized understanding of the requirements for the managerial culture of civil servants also does not fully correspond to the scientific understanding of managerial culture as a complex component.
Perspective Researches of Managerial Culture in the Sphere of Public Administration at the Present Stage

Published: April 2021

The ways of development and structural changes of the Ukrainian society also affected the public administration, which should gradually be transformed into a more open one in the dialogue with the civil society, to become public. Public administration, if it is effective, must fully provide, satisfy, and regulate the activities of society, state institutions, local governments, civil society institutions, labor collectives, and so on. In addition, it is also important to say that the changes and transformations that take place in management affect the development of new principles of management itself in practice, and the modern perception and use of social values in the management process. The outlined changes and transformations determine and, in some way, promote the processes of effective approach to the problems of research of modern directions of formation, development and comprehension of managerial culture. Mostly, this process is related to the real life of society, the state, government agencies, civil society institutions, effective social cooperation between the state and civil society, and so on. In fact, the formation of the components of managerial culture, its place and role in public administration largely depend on these factors. We understand managerial culture as a socio-political phenomenon, which in the process of its formation, is structured into a sufficient public institution, which has an impact on management policy by the state, society, various groups, local communities, social organizations, etc. Hence, the importance of managerial culture increases, which is formed during a certain socio-historical time. We realize that a manager already has some established qualities of managerial culture. Its shaping, and subsequent formation, occurs in a variety of socio-cultural circumstances, the environment, are both organized and spontaneous. The professional activity and work of a public manager depends on it in many respects. Based on this, the tasks of studying managerial culture from the standpoint of new views of the transition to public administration; identification of perspective areas for both scientific and theoretical analysis, for practical application are crucially important today.

With the introduction of environmental legislation such as the Restriction of Hazardous Substances (RoHS), lead (Pb)-free materials have made their way into the electronics manufacturing industry. One issue that has emerged is that Pb-free solder alloys can initiate and grow tin whiskers under specific conditions. These whiskers are thin, highly conductive filaments which have the potential to grow and can cause field failures in many applications. Most concerning with respect to tin whiskering are high reliability applications such as aerospace, automotive, and medical.

Bismuth (Bi) is being considered for inclusion in solder alloys to replace the current industry standard (SAC 305) and provide improved thermomechanical and vibration reliability. In this paper, we discuss whisker formation of several Bi-bearing alloys after long-term (12,000 hours), ambient high humidity (25°C/85% RH) storage. Three alloys containing Bi, in addition to SAC 305 (Sn-3.0Ag-0.5Cu), were considered.  These alloys were Violet (Sn-2.25Ag-0.5Cu-6.0Bi), Sunflower (Sn-0.7Cu-7.0Bi), and Senju (Sn-2.0Ag-0.7Cu-3.0Bi). The boards were fabricated with electroless nickel immersion gold (ENIG) and immersion tin (ImmSn) finishes and populated with parts having Cu and Fe42Ni alloy leads and chip parts, with half of assemblies cleaned and half cleaned and contaminated with low levels of NaCl.

This paper is the third in a series of three in which we share more in-depth characterization of features of interest from the small outline transistor (SOT) inspection. Discussion regarding the role of Bi in the overall stress state of the joint will also be provided.
