Determinants of Overweight and Underweight among Children under 5 in Kazakhstan
Authors: Kurmanov Bakhytzhan , Pena-Boquete Yolanda , Samambayeva Aizhan , Makhmejanov Galym
Published: November 2021

Background:

During the last 10 years, the prevalence of underweight has decreased considerably in Kazakhstan and, nowadays, it is set under 3% for children under 5 years old. However, the prevalence of overweight, which was not important at all in the 90s, is reaching 10% for children under 5 nowadays. This means that there is a co-existence between being underweight and overweight in the same country and, in some cases, within the same region. In order to design policies addressing both problems and avoiding policies, which may solve underweight but worsening overweight, and vice versa, the aim of this paper is to analyse the socioeconomic determinants of the two problems.

Methods:

We estimate the probability of occurrence using the Multiple Indicator Cluster Survey (MICS) collected by the United Nations Children’s Fund (UNICEF) and Agency of Statistics of the Republic of Kazakhstan for the years 2006, 2010-2011 and 2015. This survey includes a questionnaire for children younger than 5 years old containing information on maternal and child health. We consider that a child is overweight if she/he falls over two standard deviations of the World Health Organization standards (WHO) for her/his age. Similarly, we consider that a child is underweight if she/he falls below the two standard deviations of the WHO standards.

Results:

Children of mothers with higher education have a higher probability of being overweight (6,8%) and less probability of being underweight (-5,5%). This effect disappears for children older than 2 years old. Children of Russian origin and other ethnic groups show a lower probability of being overweight in comparison with their Kazakh peers. Being born in the highest wealth quintile reduces the risk of a child under 2 years old being underweight (-2,9%). On the other side, children in rich families at age 2-4 years old have a higher probability of being overweight (3,7%).

Conclusion:

Health policy aimed to improve family and institution´s knowledge on child nutrition could be effective measures to reduce infant overweight.

Introduction:

This study aimed to determine the prevalence of selected risk factors for cardiometabolic disease among university staff at the University in the Western Cape, Cape Town, South Africa. The secondary objective was to examine the association between the indicators of obesity and CMD risk factors.

Methods:

A total of 73 (men = 20 (27.4%); women = 53 (72.6%)) healthy university staff members, which include academics, administrators, and support staff, with a mean age of 39.2 years partook in the study. Anthropometric and physiological variables were assessed and analysed.

Results:

The categorisation of body mass index showed that 35% and 45.3% of men and women were obese, respectively. The prevalence of central obesity and waist-to-height ratio (WHtR) showed that 25% of men and 60.4% of women were at a high risk of developing a CMD, while 25% and 71.7% of men and women were at high risk for waist-to-hip ratio (WHR), respectively. The prevalence of hypertension revealed that 35% and 20.8%, 5% and 17%, and 15% and 9.4% of men and women had elevated hypertension (stage I) and hypertension (stage II) status, respectively. Furthermore, 25% and 35.8%, and 5% and 11.3% of men and women were pre-diabetic and diabetic, respectively, while for total cholesterol levels, 40% and 34%, and 15% and 15.1% of men and women were at borderline high and high risk, respectively.

Conclusion:

There was a high prevalence of selected cardiometabolic disease risk factors among university staff that requires urgent intervention. Lifestyle modification, weight management, and wellness programmes focusing on health education, regular physical activity participation, and a healthy diet should be prioritized.
The Role of Antigen Rapid Diagnostic Test in COVID-19 Diagnosis
Authors: Joji Ronni Mol , Shahid Mohammad
Published: November 2021

Since the emergence of a novel infection due to the SARS-CoV-2 virus (COVID-19), the World Health Organization has urged countries to develop diagnostic tests to combat the pandemic. Molecular assays were developed following the release of the gene sequence of the virus in January 2020. Reverse transcription-quantitative PCR (RT-qPCR) is taken as the gold standard for the diagnosis of COVID-19. However, due to its limitations, highly sensitive methods for detecting antigens (antigen rapid diagnostic tests) have been developed that would help in a timely and accurate diagnosis. Antigen rapid diagnostic tests (Ag-RDTs) can help guide patient management at the point of care by random screening, re-testing, and timely decision-making in the field of public health. When the affordability and validity of the diagnostic assay are involved, no assay can show 100% correct results. Further studies need to be done to better understand the response of the Ag-RDTs in different settings. Nevertheless, Ag-RDTs can play a complementary role in the response and case management of COVID-19.

Published: November 2021

This research paper is devoted to the thorough study of phraseological units in terms of national connotation. Phraseological units that reflect national and cultural identity are the beauty and art of language. Phraseologisms, by their very nature, are a means of expressing imagery in a language, but they also serve to reveal the national culture, character, humor, grief, and anxiety of a people. For this reason, phraseology is the most important unit of poetic language used in the literary text to fully express the image, character, character, and to illustrate and exaggerate events, happenings, and situations. The phraseological resources of each language reflect the socio-historical events, moral and spiritual-cultural norms, mental and psychological conditions, religious ideas, national traditions, and customs of the people. Such phraseologies belonging to the vocabulary of a particular language community are among the national language tools. They polish the national color of the work of art and create a strong emotionality while emphasizing the popularity and originality of the language.

Information disorder, the Triumvirate, and COVID-19: How media outlets, foreign state intrusion, and the far-right diaspora drive the COVID-19 anti-vaccination movement
Authors: Bajwa Aman
Published: November 2021

Information disorder has become an increasing concern in the wake of the 2016 US presidential election. With the state of the COVID-19 pandemic rapidly evolving in all facets, the vaccination debate has become increasingly polarized and subjected to a form of politics based around identity markers such as nationality, ethnicity, gender, and ideology. At the forefront of this is the COVID-19 anti-vaccination movement that has gained mainstream attention, leading to conflict with pro-vaccinationists. This has paved the way for exploitation by subversive elements such as, foreign state-backed disinformation campaigns, alternative news outlets, and right-wing influencers who spread false and misleading information, or disinformation, on COVID-19 in order to promote polarization of the vaccine debate through identity politics. Disinformation spread sows confusion and disorder, leading to the erosion of social cohesion as well as the potential for real-world conflict and violence. As a result, the article below will generate further understanding of the modern-day spread of disinformation, the strategies and tactics utilized by state and non-state actors, the effects of its exposure, and the social-psychological processes involved in its spread and resonance. Furthermore, in countering this phenomenon, this article recommends a collaborative framework involving emphasis on critical media literacy skills, citizen participation, and development of counter-offensive capabilities towards state-backed information operations.

Published: November 2021

Experimental biomechanical study was performed in 60 spine specimens. Anterior wedge osteotomy and fixation of a specimen in a kyphotic position modeled kyphotic deformity. Deformity correction with various instrumentation systems was firstly performed by maximal extension of segments adjacent to kyphosis-producing block, and carried on after crossing of intervertebral anatomical structures. The study resulted in defining rational approach to surgical correction of posttraumatic deformities in the thoracic and lumbar spine. Minor kyphotic deformities are effectively corrected by instrumentation without mobilization of the spine. Large unfixed kyphosis sometimes requires anterior mobilization. Cases with rigid posttraumatic kyphotic deformity should be operated on with combined mobilization of the spine.

BACKGROUND

The COVID-19 pandemic prompted safety-net health care systems to rapidly implement telemedicine services with little prior experience, causing disparities in access to virtual visits. While much attention has been given to patient barriers, less is known regarding system-level factors influencing telephone versus video-visit adoption. As telemedicine remains a preferred service for patients and providers, and reimbursement parity will not continue for audio visits, health systems must evaluate how to support higher-quality video visit access.

OBJECTIVE

This study aimed to assess health system–level factors and their impact on telephone and video visit adoption to inform sustainability of telemedicine for ambulatory safety-net sites.

METHODS

We conducted a cross-sectional survey among ambulatory care clinicians at a hospital-linked ambulatory clinic network serving a diverse, publicly insured patient population between May 28 and July 14, 2020. We conducted bivariate analyses assessing health care system–level factors associated with (1) high telephone adoption (4 or more visits on average per session); and (2) video visit adoption (at least 1 video visit on average per session).

RESULTS

We collected 311 responses from 643 eligible clinicians, yielding a response rate of 48.4%. Clinician respondents (N=311) included 34.7% (n=108) primary or urgent care, 35.1% (n=109) medical, and 7.4% (n=23) surgical specialties. Our sample included 178 (57.2%) high telephone adopters and 81 (26.05%) video adopters. Among high telephone adopters, 72.2% utilized personal devices for telemedicine (vs 59.0% of low telephone adopters, P=.04). Video nonadopters requested more training in technical aspects than adopters (49.6% vs 27.2%, P<.001). Primary or urgent care had the highest proportion of high telephone adoption (84.3%, compared to 50.4% of medical and 37.5% of surgical specialties, P<.001). Medical specialties had the highest proportion of video adoption (39.1%, compared to 14.8% of primary care and 12.5% of surgical specialties, P<.001).

CONCLUSIONS

Personal device access and department specialty were major factors associated with high telephone and video visit adoption among safety-net clinicians. Desire for training was associated with lower video visit use.

Background. Atopic dermatitis is the most common inflammatory skin disease in childhood, affecting almost 20 % of children. Food allergies affect one of three children with atopic dermatitis, and allergies to peanuts, eggs and milk are the predominant food allergies in the world. The purpose was to assess the prevalence of food allergies in the group of patients with atopic dermatitis, to determine the association of food allergies with anamnestic and clinical parameters of atopic dermatitis. Materials and methods. Children with atopic dermatitis (n = 116) were included in the study from September 2020 to August 2021 in Kyiv, Ukraine. Food sensitization was established by determining specific immunoglobulin E (sIgE) to food allergens using immunochemiluminescent method on the ImmunoCAP 100 system (Thermo Fisher Scientific Inc., Phadia, Sweden). Results. The average age of children in the main group (59 boys and 57 girls) was 6.8 years. All 116 patients at the time of examination had manifestations of atopic dermatitis in the form of erythematous itchy rash. The number of children with food allergy was 23 (19.8 %). Among food allergens, positive sIgE were found: in 14 patients (12 %) — to milk, in 13 (11.2 %) — to eggs, in 5 (4.3 %) — to fish, and in 4 people (3.4 %) — to hazelnuts. Food sensitization was significantly more common in children with moderate-to-severe atopic dermatitis than in the group of patients with mild atopic dermatitis (χ2 = 7.555, p < 0.05). Children with food sensitization had an earlier onset of atopic dermatitis — the average age of manifestations onset was 8 months, and in the group of children without food allergy, it was 18 months. Children with a parental history of atopic diseases were significantly more likely to have concomitant food allergy (χ2 = 12.831, p < 0.05). Conclusions. Given the significant association between early onset as well as moderate-to-severe atopic dermatitis and food sensitization, it is likely that food sensitization occurs primarily through an inflamed skin barrier in eczematous skin, which could potentially lead to clinical food allergy.

Background. Relevant in pediatrics is the use of indicators of quality of life of children to personify the treatment process, monitoring the course of the disease. In recent years, there has been increasing research on the role of vitamin D and calcium in the human body. The study was aimed to assess the quality of life of infants and to establish the possibility of medical correction of the main indicators of quality of life under the influence of the combined use of vitamin D and calcium. Materials and methods. We observed 30 clinically healthy infants who received 2.5 ml of vitamin D and calcium 3 times a day for 2 months. We have created our questionnaire on the quality of life of infants. Methods of variation statistics are used. Results. Based on the correlation analysis in infants before treatment, there was found a positive relationship between quality of life and the state of biological resistance (r = +0.51; p < 0.05); natural feeding (r = +0.56; p < 0.05); symptoms of functional gastrointestinal disorders (r = +0.58; p < 0.05); parameters of emotional status (r = +0.62; p < 0.05); signs of autonomic dysfunction syndrome (r = +0.63; p < 0.05); neuropsychological development (r = +0.65; p < 0.05); features of adaptability (r = +0.66; p < 0.05). The results of the treatment with vitamin D and calcium in the study of the correlation diagram of the relationship between quality of life and the established indicators of the development of infants demonstrated no correlation between the quality of life and symptoms of functional gastrointestinal disorders and symptoms of autonomic dysfunction. After treatment, there was a decrease in the strength of the correlation between the quality of life of infants and the parameters of emotional status (r = +0.36; p < 0.05); indicators of neuropsychological development (r = +0.35; p < 0.05), and ability to adapt (r = +0.44; p < 0.05). Conclusions. The сombined use of vitamin D and calcium in the recommended dose of 2.5 ml 3 times a day for 2 months is characterized by a high safety profile, improves the quality of life of a child, and can be recommended for infants.

Published: November 2021

Background. The problem of timely diagnosis of complications of acute destructive pneumonia accompanied by pyofibrothorax remains relevant. The study was aimed to investigate the features of ultrasound diagnosis (ultrasound) of the condition of the visceral and parietal pleural lamina in acute destructive pneumonia in children at different stages of the disease. Materials and methods. In the departments of purulent surgery and pulmonology of the Regional Children’s Hospital of Dnipro for the period of 5 years, there were observed about 475 children aged from 1 to 17 years with pneumonia, purulent-destructive changes in the lungs and pleura. For analysis and further study, we choose a group of 50 patients of different age groups, who underwent ultrasound in real time without prior preparation of patients. The condition of the parietal and visceral pleural lamina at the different stages of diagnosis and treatment was studied. Results. A group of patients aged from 4 to 10 years was performed an ultrasound of the pleural cavities in real time without prior preparation on the paraspinal, scapular, axillary, midclavicular, and thoracic lines when admitted to the hospital and on the first day of treatment. Ultrasound was used to determine the structure and volume of free fluid as well as the condition of the parietal and visceral pleural lamina, their thickness, and other features. The use of ultrasound allowed diagnosing the early manifestations of pyofibrothorax and determining the condition of the parietal and visceral pleural lamina in the children with destructive pneumonia. Conclusion. Further improvement of the algorithm of ultrasound diagnosis of acute destructive pneumonia in children with pyofibrothorax will reduce radiation exposure to a child’s body, increase the efficiency of the development and improvement of treatment methods at the stages of pyofibrotorax, reduce the duration of inpatient treatment.

Authors:   Department of Oral Biology, University of Illinois at Chicago College of Dentistry, Chicago, USA, Guirado E , George A
Published: November 2021

Matrix metalloproteinases (MMPs) have been implicated not only in the regulation of developmental processes but also in the release of biologically active molecules and in the modulation of repair during tertiary dentine formation. Although efforts to preserve dentine have focused on inhibiting the activity of these proteases, their function is much more complex and necessary for dentine repair than expected. The present review explores the role of MMPs as bioactive components of the dentine matrix involved in dentine formation, repair and regeneration. Special consideration is given to the mechanical properties of dentine, including those of reactionary and reparative dentine, and the known roles of MMPs in their formation. MMPs are critical components of the dentine matrix and should be considered as important candidates in dentine regeneration.

Authors: Kumar Dr. K. Naveen
Published: November 2021

Abstract: Recently, a machine learning (ML) area called deep learning emerged in the computer-vision field and became very popular in many fields. It started from an event in late 2012, when a deep-learning approach based on a convolutional neural network (CNN) won an overwhelming victory in the best-known worldwide computer vision competition, ImageNet Classification. Since then, researchers in many fields, including medical image analysis, have started actively participating in the explosively growing field of deep learning. In this paper, deep learning techniques and their applications to medical image analysis are surveyed. This survey overviewed 1) standard ML techniques in the computer-vision field, 2) what has changed in ML before and after the introduction of deep learning, 3) ML models in deep learning, and 4) applications of deep learning to medical image analysis. The comparisons between MLs before and after deep learning revealed that ML with feature input (or feature-based ML) was dominant before the introduction of deep learning, and that the major and essential difference between ML before and after deep learning is learning image data directly without object segmentation or feature extraction; thus, it is the source of the power of deep learning, although the depth of the model is an important attribute. The survey of deep learningalso revealed that there is a long history of deep-learning techniques in the class of ML with image input, except a new term, “deep learning”. “Deep learning” even before the term existed, namely, the class of ML with image input was applied to various problems in medical image analysis including classification between lesions and nonlesions, classification between lesion types, segmentation of lesions or organs, and detection of lesions. ML with image input including deep learning is a verypowerful, versatile technology with higher performance, which can bring the current state-ofthe-art performance level of medical image analysis to the next level, and it is expected that deep learning will be the mainstream technology in medical image analysis in the next few decades. “Deep learning”, or ML with image input, in medical image analysis is an explosively growing, promising field. It is expected that ML with image input will be the mainstream area in the field of medical image analysis in the next few decades.
