Authors: Huang Ying , Jiang Fachao , Xie Haiming
Published: October 2021

The new energy of concrete truck mixers is of great significance to achieve energy conservation and emission reduction. Unlike general-purpose vehicles, in addition to driving conditions, upper-mixing system conditions, operation scenarios, and variable loads are the key factors to be considered during the new energy of concrete truck mixers. This study focuses on the machine-learning-based approximate optimal energy management design for a concrete truck mixer equipped with a novel extended-range powertrain from two aspects: trip information and energy management strategy. Firstly, an optimal control database is constructed, which benefits from a global optimization algorithm with dimension reduction for the constrained time-varying two-point boundary value problems with two control variables, and the driving data analysis through machine learning and data-driven methods. Then, different machine-learning-based driving condition identifiers are constructed and compared. Finally, a vehicle mass and power demand of an upper-part system based novel neural network energy management strategy is designed based on a constructed optimal control database. Simulation results show that the intelligent optimization algorithm based on the ML of trip information and energy management is an appropriate way to solve the online energy management problem of the concrete truck mixer equipped with the proposed novel powertrain.
Static Eccentricity Fault Analysis of Surface-Mounted Permanent Magnet Electromotor with Skewed Slots Based on 2D FEA
Authors: Wang Li
Published: October 2021

It is of significance to analyze the performance of eccentric electromotor for the research on the electric vehicle wheel drive system’s operational reliabilities. We developed a fast equivalent algorithm in which the two-dimensional finite element calculation results are translated into three-dimensional calculation results. An electromotor with skewed slot was decomposed into straight-slot electromotor units that were series-wound. A prototype electromotor driven by square wave current under healthy and eccentric conditions was calculated, and the computation accuracy of the equivalent algorithm was analyzed. The air-gap magnetic field and induced electromotive force were calculated and contrasted. The study results indicate that the magnetic field distribution and the induced electromotive forces of winding elements with different axis positions were affected transparently by grievous eccentricity, yet the induced electromotive force of one phase winding and average value of torque remained virtually invariable. The reference to reliability analysis of electric vehicle wheel drive system is provided.

Published: October 2021

The article examines some issues of modern housing policy aimed at liberalizing housing legislation. The concept of the liberalization of housing legislation is highlighted and its main features are revealed; individual problems affecting the formation of housing legislation are identified. It is shown that the effectiveness of the implementation of the right of everyone to housing, enshrined in Article 40 of the Constitution of the Russian Federation, primarily depends on how effectively the norms of housing legislation are applied. The author determines that the necessary condition for the effective use of these norms is the reflection of modern trends in the development of housing law in general and its specific institutions in particular. In this regard, the improvement of housing legislation should follow the path of liberalization, expansion of the rights and freedoms of subjects of housing legal relations. The article can be used when giving lectures and conducting practical classes in the field of Jurisprudence.
Experience of distance learning in modern Russia (philosophical and educational experiments)
Authors: Kuzenkov Pavel Vladimirovich , Panishchev Aleksey Leonidovich
Published: October 2021

This article is devoted to the issue of distance learning for students. This form of education has become common in Russia in conditions of high risk of the coronavirus infection COVID-19. However, there are concerns that distance learning will become a regular norm. Meanwhile, the consequences of this may be negative, since education and promotion of students’ moral growth will become essentially impossible. The entire education system will be reduced to informing students about certain disciplines. Thus, distance learning should not take the form of a daily norm in the education system.

Science, technology and education as factors of national security
Authors: Kolin Konstantin Konstantinovich
Published: October 2021

The article shows that for the development of science, technology, and education, it is necessary to create an adequate information and analytical system to support the adoption of effective management decisions. One of the main difficulties of this task is that it should be solved comprehensively, and not in fragments, as it is done at present. After all, in the structure of the Russian Government there is no body for centralized management of the solution of this issue. Therefore, many state programs in this area are not coordinated with each other and are not supported by the necessary personnel, standards, and legal and information provision. All this will have to be created anew in the context of increasing attempts to isolate Russia economically and politically by the United States and its supporters in the countries of the European Union (EU). The author suggests using this geopolitical situation to review the strategy and tactics of Russia's scientific and technological development, making it a priority to increase the efficiency of using its own intellectual potential and expand scientific and technological cooperation with other countries. First of all, it should be the BRICS countries, the Eurasian Economic Union, as well as China, India, Iran and South Korea, which also face acute problems of scientific and technological development.
Development of Advanced High Strength Automotive Steels
Authors: Tisza Miklós
Published: October 2021

In recent decades, the automotive industry has faced ever-increasing demands. Increasing requirements can be observed in terms of both consumer expectations and legal requirements. On the consumer side, there is a demand for cars that are as economical as possible with lower fuel consumption, but providing also greater comfort and safety. These requirements are accompanied, from a legal point of view by more rigorous environmental regulations and requirements concerning the reduction of harmful emissions. Meeting these often-contradictory requirements is a growing challenge for car manufacturers and raw material suppliers, as well. Meeting the requirements in the most versatile way has resulted in tremendous progress over the last 40–50 years, both in the automotive industry and in the production and development of raw materials. The first part of this series of papers summarizes the main requirements in the automotive industry, as the main driving forces for material developments. Furthermore, the main types and properties of traditional high-strength steels, as well as the so-called first-generation Advanced High-Strength Steels will be introduced. In the second part, the main types and manufacturing processes of second generation advanced high-strength steels will be analyzed and some of the current steel developments will be presented through the results of the three generations of Advanced High-Strength Steels.

Authors: Bíró Tamás , Renkó József Bálint
Published: October 2021

In material testing and manufacturing processes, creating thin layers is a widely used method for structure development or for surface treatment purposes. Despite its widespread use, the physical background of the layer development process is currently under-researched. Its examination requires the development of procedures and tools that, in combination with the existing tools, can help to understand these processes. The development of microfluidic cells is a way to solve this problem. In this paper, a newly developed microfluidic cell is presented, which also offers a solution to several problems encountered when using previous designs.

Published: October 2021

Purpose: To explore the association of Australian general practitioner (GP) registrars’ responses to uncertainty with their in-consultation information-, advice- and assistance-seeking.Design/methodology/approach: A cross-sectional analysis of data from the Registrar Clinical Encounters in Training (ReCEnT) cohort study in four Australian states. In ReCEnT, GP registrars record details of 60 consecutive consultations, six-monthly, three times during training.Outcome factors in logistic regression models included whether the registrar sought in-consultation information or assistance from (i) their supervisor or (ii) an electronic or paper-based source. Independent variables were the four independent subscales of the Physicians’ Reaction to Uncertainty (PRU) instrument, as well as registrar, practice and consultation variables.Findings: 589 registrars contributed details of 70,412 consultations.On multivariable analysis, scores on the two ‘affective’ PRU subscales ‘anxiety regarding diagnosis/management’ (OR 1.03; 95% confidence intervals [CIs] [1.01, 1.05], p = 0.003) and ‘concern about a bad outcome’ (OR 1.03; 95% CIs [1.01, 1.06], p = 0.008) were significantly associated with seeking supervisor assistance. There was no association with ‘behavioural’ subscales ‘reluctance to disclose uncertainty to patients’ and ‘reluctance to disclose mistakes to physicians’.None of the PRU subscales were significantly associated with information-seeking from electronic or hard copy sources.Research implications: Further research is required to explore the role of uncertainty within registrar–supervisor interactions and to define the role of supervisors in registrars’ functional adaptation to clinical uncertainty (including how best to support and train supervisors in this role).Practical implications: GP registrars’ ‘affective’ responses to clinical uncertainty are associated with assistance-seeking from clinical supervisors. While in-consultation assistance-seeking may promote registrars’ tolerance of uncertainty, it may also contribute to supervisor workload.Originality/value: This is the first study to examine trainees’ levels of uncertainty and their seeking of information and assistance.Limitations: We have not investigated whether registrars’ seeking assistance resolved or attenuated, for the index problem, their anxiety or concern.

Tectona grandis L.f. (Teak) is a highly cultivated forest species in Brazil. When industrially processed, it generates a large amount of sawdust, a waste that has limited reuse and accumulates in the industrial yards. The aim of this study was to evaluate the effect of fresh teakwood sawdust on the development of Urochloa brizantha (Hochst. ex A.Rich.) R.D.Webster cv. Xaraés in a nursery. The treatments consisted of concentrations of 0, 5, 10, 20, 33 and 50% of sawdust, arranged in four randomized blocks in split-plots. At 45, 75 and 120 days, plant heigh (h), average tillers diameter (d), number of live (nll) and dead leaves per plant, fresh and dry mass of shoots and roots, and Dickson's quality index (dqi) were measured.  There was a decrease in h growth, d, nll, fresh and dry mass of shoots and roots and in the dqi of the cv. Xaraés as it increased to concentration of wood sawdust in the substrate. This negative effect can be attributed to the high C/N ratio of sawdust (196/1), which influences the decomposition of organic matter. In addition, the possible Teak allelopathic effects, which are the subject of other studies, should be considered. Unlike the other variables, number of live leaves was not influenced by the treatment with 5% sawdust. Teakwood sawdust has negative effects on the U. brizantha cv. Xaraés development.

Authors: Meloni Diego , Martínez Carlos Arberto , Targa María Gabriela , Fraño Alicia , Catán Alejandra
Published: October 2021

The use of herbicides is a usual practice in E. camaldulensis nurseries and plantations. The most widely used herbicide is glyphosate, whose drift damages this plant leaves. Although the mechanism of action of glyphosate is well known, it is not clear which alterations lead to the death of plants. The aim of this work was to assess the physiological and anatomical responses of leaves of E. camaldulensis seedlings to glyphosate application. Tests were performed on one-year-old seedlings sprayed with 0, 65 and 130 g a.e. ha-1 glyphosate. Ten days after the application, we measured gas exchange and fluorescence emission of chlorophyll a. We also quantify the concentrations of chlorophyll a, shikimate, carbohydrates, K+ and Mg2+, and the anatomical parameters of epidermis and mesophyll. Data was contrasted using Fisher’s test (p<0.05). We concluded that glyphosate alters the physiology of E. camaldulensis, inhibiting photosynthesis, changing the metabolism of carbohydrates and the ionic homeostasis. Tissue disorganization, heavily marked at the level of mesophyll, indicates definite alterations.

Moreover, our devices own the lowest power consumption and “set” voltage (0.2 V) among the simplest perovskite-based memory devices (inorganic ones are also included), which are no need to require double metal electrodes or any additional insulating layer. They also demonstrate repeatable resistance switching behaviour and excellent retention time. We envision that 1D OIHPs can enrich the low-dimensional hybrid perovskite library and bring new functions to low-power information devices in the fields of memory and other electronics applications.

Entre las tareas más complejas que tiene la humanidad para alcanzar los Objetivos de Desarrollo Sostenible de las Naciones Unidas al 2030, están erradicar el hambre, la pobreza y la inequidad de género en el ámbito laboral, (Organización de las Naciones Unidas, 2019).  América Latina, a pesar de ser una de las regiones más afectadas por estos aspectos, posee paisajes excepcionales, y una gran biodiversidad y pluriculturalidad. (Comisión Económica para América Latina y el Caribe, 2018). Sin embargo los territorios andinos de Perú, Bolivia, Ecuador y Argentina constituyen el espacio geográfico con extraordinaria capacidad productiva de alimentos nativos (Balbin Ordaya, 2014, p. 33), que debido a su alta calidad nutricional y bondades terapéuticas, se los denomina nutraceúticos. (Balbin Ordaya, 2014, p. 28).

 Dentro de todos los cultivos de la región Andina, la quinua Chenopodium quinoa[1], es uno de estos alimentos nativos, denominado grano de oro, por todas las diversas propiedades nutritivas que posee. (Organización de las Naciones Unidas para la Alimentación y la Agricultura, 2012).  Si a ello le sumamos la revalorización del territorio rural y la presencia de proyectos e iniciativas comunitarias que promueven el empoderamiento de las mujeres como principales líderes del cultivo y su procesamiento, la quinua constituye una opción saludable, económicamente viable y una de las oportunidades que tienen los pueblos andinos para generar ganancias, reducir la pobreza, erradicar el hambre y contribuir a promover la equidad de género en el trabajo rural, subestimado en la región.

26.	Chronic periodontitis and endothelial dysfunction In patients with arterial hypertension
Authors: Eremin Andrey , Lepilin Alexandr , Lipatova Tatiana
Published: October 2021

The work offers a view at the data obtained through an examination of 120 patients with chronic generalized periodontitis (CP) and arterial hypertension (AH). The check-up included clinical examination, immunohistochemical, morphometric studies, as well as evaluation of the endothelium vasodilating function. CP in patients with hypertension features more significant changes in the quantitative density of gum cells positive to ET-1, endothelial NO-synthase, if compared to the CP values in patients with no background somatic pathology. Changes affecting vasoactive mediators in the gum are associated with a systemic inflammatory response and a violation of the endothelium vasodilating function. Periodontitis remission can be achieved with the therapy of the neurotransmitter imbalance.

На основании накопленного опыта эксплуатации сооружений Минской очистной станции и обзора источников информации определена схема гидробиологического анализа активного ила, приведена форма регистрации результатов проведенного анализа. Для количественного учета нитчатых микроорганизмов разработана собственная пятибалльная система. Для нитчатых микроорганизмов, выявленных в активном иле, на основании анализа литературных данных определены условия, благоприятствующие их массовому развитию. В течение длительного периода времени, включающего разные сезоны года, проведена апробация усовершенствованной методики для мониторинга состояния иловой суспензии очистных сооружений двух площадок станции: классических четырехкоридорных аэротенков-вытеснителей первой площадки и биореакторов с каскадной денитрификацией второй площадки. Определены представители нитчатых микроорганизмов, постоянно обитающие в очистных сооружениях, выявлены доминирующие виды. Проведено сопоставление результатов анализа нитчатых форм и седиментационных характеристик активного ила. Сделаны заключения об особенностях биоценоза аэротенков первой площадки и биореакторов второй площадки, идентичности по видовому составу сообществ нитчатых бактерий, влиянии состава сточных вод и условий их очистки (нагрузка на ил, наличие зон с разным уровнем аэрации) на свойства иловой суспензии.

Based on the accumulated experience in operating the Minsk Wastewater Treatment Facilities and a review of information sources, a scheme for the hydrobiological analysis of activated sludge was determined, and a form for recording the results of the analysis was provided. For the quantitative account of filamentous microorganisms, an original five-point system was developed. Based on the literature data analysis, favorable conditions for the mass growth of filamentous microorganisms found in activated sludge were determined. Over a long period of time, including different seasons of the year, the improved methodology was tested for monitoring the state of the sludge suspension at two sites of the treatment facilities: traditional four-line continuous-flow aeration tanks at the first site and bioreactors with cascade denitrification at the second site. The species of filamentous microorganisms, permanently living in wastewater treatment structures, have been identified, and the dominant species have been determined. The results of the analysis of filamentous forms and sedimentation characteristics of activated sludge are compared. Conclusions were made about the features of the biocenosis in the aeration tanks at the first site and in the bioreactors at the second site; about the identity of the species composition of the filamentous bacteria communities, the effect of the wastewater composition and treatment conditions (sludge load, occurrence of zones with different levels of aeration) on the properties of the sludge suspension.

Проблема утилизации осадка сточных вод в последние годы становится все более актуальной для коммунального хозяйства. Приведены результаты исследования процесса суспендирования осадка известьсодержащим реагентом Дезолак, определены размеры твердых включений, что позволило рассчитать необходимую скорость вращения перемешивающего устройства: средний заутеровский диаметр частиц составил 55 мкм, плотность твердой фазы – 2211 кг/м3. Для эффективного суспендирования реагента необходимо обеспечить угловую скорость мешалки не менее 0,03 м/с. Исследованы основные критерии подобия для масштабирования аппаратов, определено, что при выборе мешалки следует учитывать критерий Фруда Fr, так как именно этот показатель для трех исследованных реакторов практически постоянен. На основании проделанной работы определено, что отношение мощности к объему перемешиваемой жидкости не может являться критерием для расчета аппаратов, оснащенных перемешивающими устройствами GMS: для данных мешалок справедливо снижение мощности на перемешивание с увеличением размеров аппарата.

In recent years the problem of wastewater sludge disposal has become more and more urgent for the municipal economy. The results of a study of the process of sludge suspending with Dezolak, a lime-containing agent, are presented; the size of solid inclusions is determined to provide for calculating the required rotation speed of the mixing device: the average Sauter particle diameter was 55 μm, the density of the solid phase was 2211 kg/m3. For effective chemical suspending the angular velocity of the mixer should be more than 0.03 m/s. The main similarity criteria for scaling the apparatus were investigated; it was determined that while choosing a mixer, the Froude criterion Fr should be taken into account, since that very indicator was practically constant for the three investigated reactors. Based on the work done, it was determined that the ratio of power to the volume of the mixed liquid cannot be a criterion for calculating devices equipped with GMS mixing devices: for these mixers, a decrease in the mixing power with an increase in the size of the device is valid.

When somebody, usually a teenager, abuses or harasses individual on the internet and other digital places, mainly on social networking platforms, this is termed as cyberbullying. Cyberbullying, like all types of bullying, produces psychological, emotional, and physical distress. Every individual's reaction to being bullied is diverse, but research has discovered certain common patterns. In a recent study, we introduced a technique called Hybrid Firefly Artificial Neural Networks (HFANN) to combat cyberbullying. Nevertheless, without considering the sentiment analysis features, accuracy of cyber bullying identification is lowered in this study. The Sentiment Analysis and Deep Learning based Cyber Bullying Detection (SADL-CDD) approach is used in the suggested research approach to address this issue. The punctuations, urls, html tags, and emoticons from the input tweet comments are removed first in this study project. Sentiment feature extraction is performed after pre-processing to improve classification accuracy. The Modified Fruit Fly Algorithm (MFFA) is used to choose the best features from the extracted features. Following feature selection, cyber bullying detection is carried out using a Hybrid Recurrent Residual Convolutional Neural Network (HRecRCNN). The experimental outcome of this study indicates the efficiency of the suggested approach. In comparison to current algorithms, the SADL-CDD method delivers improved classification performance with respect to reduced time complexity, greater precision, recall, f-measure, and accuracy.

CHALLENGES IN THE MANAGEMENT OF FIRE CRACKER BURNS OF HANDS IN A TERTIARY BURN CARE CENTER
Authors: Doshi Dharmil , Selvaraj Angeline , Suja S. , Panchapakesan K.
Published: October 2021

Fireworks related burns are one of the causes of recurring incidences of burn injuries every year during festivals. Sporadic
events are reported in family and communal celebrations / temple festivals and in funerals.
These burns are different from other burns as the burn percentage is not the major burden, but the increasing number of patients with cracker burn
injuries with loss of hand function, loss of vision and at times blast injury of the face with major tissue loss and multiple fractures (shattered
tissues), which are challenging for the reconstructive surgeon, are major concern.
These re cracker burn wounds are to be classied separately as the wounds are more like traumatic wounds than burn wounds. They are also
associated with more morbidity than mortality.
Upper limbs, mainly the hands are the most common site of injury in case of cracker burns. Blast injury while lighting crackers causes severe
damage to the tissues, and along with the added contamination of the wound, makes repair and reconstruction of such limbs a herculean task.

Published: October 2021

INTRODUCTION: Corona virus disease-19 (COVID-19) is one among the worst pandemics faced by mankind and
there are various neurological manifestations either direct or indirect effect of Corona virus. Here we report a case of foot
drop secondary to entrapment peroneal injury in COVID-19 patient as a sequelae of prone positioning.
CASE REPORT: A 55-year-old gentleman was diagnosed with RT PCR positive COVID19 and was hospitalized for severe respiratory
syndrome. HRCT thorax done showed CORADS score of 6 with severity index of 14/25. During this period, patient was on treatment according
to ICMR guidelines and prone position for about 20 hours/day for 20 days for severe pneumonia. During follow up after 15 days of discharge, he
had developed features of foot drop secondary to common peroneal nerve palsy which was later conrmed by electro diagnostic studies and nerve
ultrasound. Patient was started on oral steroids and along with supportive measures. He is followed up for a period of 3 months and has noted 50%
improvement in his symptoms.
CONCLUSION: While prone positioning should continue to be utilized in COVID-19 pneumonia as dictated by the current literature,
precaution has to be taken with it. Changing patient positioning at shorter intervals and timely mobilization are necessary.

Transposition of maxillary teeth is not very uncommon nding in clinical practice and poses a challenge to the clinician.
Maxillary canine is the most commonly involved tooth in transposition exchanging its place with either lateral incisor or rst
premolar. This case report describes successful management of a case of transposition between maxillary canine and lateral incisor involving right side
st only with an insight into etiology, treatment alternatives and treatment procedure. This case had been treated with extraction of all four 1 premolars and
involved teeth were successfully moved to their clinically normal position without any signicant damage to supporting structures or roots.

Introduction: Trochanteric fractures are among the most common injuries which are usually resulting from minimal to
moderate physical trauma to areas of bone signicantly weakened by osteoporosis. The greatest problems for the
orthopaedic surgeon to treating the unstable trochanteric fracture and the complications (implant failure, varus collapse, non-union) occur from
xation that result of instability. The implants have evolved from extramedullary implants like dynamic hip screw to the intramedullary types of
PFNA2 nail. 50 patients were included in our study from July 2019 to July 2021. 25 patient Material And Methods : s were treated with PFNA2
(Group I) and 25 patients with PFN (Group II) Nails. Mean blood loss during surgery was 153.8±10.92 Results : & 201.6±38.48 in group I &
group II respectively and the mean duration of surgery in group I and group II was 65.24+6.57 min and 85.44 + 11.08 min respectively.
Conclusion : We concluded that use of helical blade PFN is certainly better in 31A2.2 and 31A3.3 type of fracture than screw PFN.

Published: October 2021

There are 15,000 new cases of spinal cord injury per year in India. The majority of persons survive due to improved
quality of acute care compared to the past. Survival impacts Quality of Life. In developed countries quadriplegia is
associated with a poor QOL on average. South Asian QOL on average is lower than in developed countries so those with diseases are worse off. A
large part of expenditure is on early surgery and subsequent home based therapy. Most are managed at centers without medical rehabilitation units.
Once stabilized the patient is discharged for home based care. The net impact leads to lost follow-up or succumbing to associated life-threatening
complications. It is established that multidisciplinary rehabilitation improves outcomes in this population. Interventions to improve function
thereby QOL may prove cost-effective in the long run. There is no Indian data on the impact on QOL comparing acute inpatient rehabilitation to
early home based care in tetraplegia. In this study we report the long-term impact of acute medical rehabilitation with follow-up on Quality of Life
in Chronic SCI. We specically report this in Chronic SCI patients greater than 1 year from injury using the EQ5DL3, and VAS.
MICROBIOLOGICAL PROFILE, ANTIBIOTIC SENSITIVITY AND PROGNOSIS OF PATIENTS WITH FOURNIER’S GANGRENE: A PROSPECTIVE, HOSPITAL BASED STUDY FROM NORTH INDIA
Authors: Gupta Sanjay , Kumar Ajay , Deb Adiveeth
Published: October 2021

Background: Fournier's gangrene (FG) is a devastating disease that is characterized by necrotizing fasciitis of the
perineal, genital, or perianal region. Broad-spectrum antibiotics are the key component of its treatment. However, there is
paucity of data regarding the optimal empirical antibiotic therapy for FG.
Materials and Methods: Data from patients who underwent surgery for FG was retrieved from a prospectively collected departmental FG
database. Demographics, clinical characteristics, causative pathogens and drug susceptibility/resistance were evaluated. Outcome was also
assessed in terms of mortality.
Results: Fifty patients with a median age of 58.5 (40-83) years were included. The perianal region and scrotum (88%) were the most commonly
affected. Diabetes mellitus (DM) was the most common comorbidity (92%). The median time to onset of symptoms was 7 (2-15) days, and the
median duration of hospital stay was 22 (4-65) days. Ventilator requirement was required in 15 (30%) patients. The median UFGSI score was 9.5
(3-15). The overall mortality rate was 26%. A positive growth was found in specimen cultures of 48 (96%) patients. The median number of
bacterial strains that grew in the cultures was 3 (0-10). Amikacin was the antibiotic with the highest frequency of sensitivity (74%), while the
highest resistance was observed against ampicillin-sulbactam (64%). Escherichia coli was the most common microorganism (68%).
Acinetobacter baumannii and Klebsiella pneumonia were signicantly more common in patients who required mechanical ventilation. The
mortality rate was 26%. An Uludag Fournier's Gangrene Severity Index (UFGSI) score of > 9.5 and ventilatory support requirement were factors
associated with an increased rate of mortality. Acinetobacter baumannii was the only microorganism which was associated with an increased
mortality rate.
Conclusion: Causative pathogens in FG appeared to be shifting; thus, empirical antibiotic treatment for this disease should be modied. We
recommend 3rd-generation cephalosporin, metronidazole and amikacin for empirical therapy.
STRESS FRACTURE AT DOCKING SITE AFTER BONE TRANSPORT MANAGED WITH INTRAMEDULLARY INTERLOCKING NAIL AND ILIAC AUTOGRAFT - A RARE CASE REPORT
Authors: P Mahajan Neetin , C Patil Tushar , A Jain Kevin , Dadhaniya Ravi
Published: October 2021

INTRODUCTION : Distraction osteogenesis was introduced by Ilizarov and further developed by Cataneo et al. The
concept of formation of new bone and soft tissues from distraction osteogenesis and freshening the sclerosed bone ends by
corticotomy for stronger bony union and consolidation is applied here. Here we present a CASE REPORT : rare case of young adult operated by
tibial bone transport using monolateral external xator, who presented to us after refracture near the docking site. We managed this patient with
intramedullary reamed nailing and iliac crest autografting, showing good bony union and functional outcome at 3 months postoperatively.
CONCLUSION : Thus from previous literature and our case ndings, we conclude that re-fractures and other complications of bone transport
can be effectively managed by intramedullary reamed nailing leading to good bony union and fracture consolidation. The intramedullary nail
provides rigid stability to both new bone regenerate due to callotasis and union at docking sit, signicantlydecreased rates of future refractures.
This signicantly decreases patients morbidity and delivering satisfactory functional outcome.

Published: October 2021

SSPE is a chronic complication of measles with a delayed onset and nearly fatal outcome. This “slow virus infection” results from a persistent infection with an altered measles virus, that is harboured intracellularly in the CNS. Patients usually presents with cognitive decline and myoclonus but atypical presentations are also quite common. Our case is of a 9 year old male child , previously neurodevelopmentally normal, presented with 4 months history of frequent fall due to jerky movements of the left upper and lower limbs which progresses to involve left half of the body, reduced attention span, cognitive decline and loss of speech. During hospitalisation, despite treatment with antibiotics , steroids , and antiepileptics ,disease progressed with myoclonic jerks , altered sensorium and nally child became comatose. CSF study is normal but MRI and EEG shows abnormalities. Based on clinical features and history of exanthematous illness at 6 months of age, measles igG antibody titres in CSF were tested , which came to be highly elevated conrming SSPE.
CLINICAL EFFECTIVENESS OF FIXED DOSE COMBINATION OF EMPAGLIFLOZIN AND LINAGLIPTIN (EMPA/LINA) IN PATIENTS WITH TYPE 2 DIABETES MELLITUS UNWILLING TO CONTINUE BASAL INSULIN THERAPY: A REAL-WORLD EXPERIENCE IN INDIAN SETTING

Published: October 2021

Many T2DM patients are reluctant to continue injectable insulin therapy affecting medication adherence. The objective
was to investigate the clinical effectiveness with empagliozin/linagliptin (EMPA/LINA) combination in patients
unwilling to continue insulin therapy. In this retrospective assessment, a total of 60 patients [(41 men, 19 women); age (± S.D.) 53.38 ± 8.49 years
and disease duration 5.67±1.89 years; baseline HbA1c: 7.1±0.58%; BMI: 28.25±4.07 kg/m2 were initiated with EMPA/LINA (25/5 mg) after
thorough assessment. During 12-week period, there was modest improvements in glycemic prole [baseline vs. endpoint; HbA1c: 7.1±0.58%
versus 7.1±0.55% (p < 0.63), FPG 129±14 mg/dl versus 125±9.3 mg/dl, PPG 154±18 mg/dl versus 143±11 mg/dl (p=0.01), proportion of patients
achieving A1C goal with no major hypoglycemia was improved from 37% to 81.48%. The incidence of overall hypoglycemia was reduced. These
ndings suggest that patients with stable glycemic status reluctant to continue insulin may have effective transition to EMPA/LINA therapy
COVID-19: UNFOLDING REASONS FOR LOW PREVALENCE AND MILDER CLINICAL PRESENTATION OF SARS-COV-2 INFECTION IN CHILDREN
Authors: Kushwaha Saurabh , Devi Uma
Published: October 2021

Coronavirus disease 2019 (COVID-19) rst reported in Wuhan, China has rapidly spread globally to become a pandemic.
As on 30 August, 2021, it has affected almost 216,303,376 individuals with no available effective drug against it. Though
the disease affects individuals of all age groups and both sexes, it is observed to have low prevalence, milder manifestations and better prognosis in
children when compared to adult population. A number of asymptomatic cases have also been reported in children, which possess a great threat to
community spread of this highly infectious disease. This literature summarizes various hypotheses postulated for unfolding the reasons for low
prevalence and milder clinical presentation of COVID-19 in children.
