Authors:   , Praditpapha Athikhun
Published: April 2023

Background: COVID-19 pandemic is a public health emergency of international concern with many countries affected including Thai. Due to the nature of the work, dental practitioner is a high-risk professional to contract the disease. Many studies were conducted to study the impact of the situation on mental health of both general population and health care personnel. However, there are scant data about the stress of Thai dental practitioner caused by COVID-19 and the associated factors. 

Objectives: The primary aims of this study were to investigate the prevalence and level of stress, along with its risk/protective factors. The secondary aim was to investigate the impact of COVID-19 pandemic consequences on the stress of Thai dentists during the COVID-19 pandemic. 

Materials and methods: In this cross-sectional study, a questionnaire was developed and distributed via social media from April 24 to May 5, 2020. Demographic, work-related, and financial and socioeconomic status were collected as predictors of stress. Self-administered Stress Evaluation Form-20 (SASEF-20) was used to capture the level of stress. Also, specific questions about COVID-19 were asked to help explore the pandemic’s impact on dentists' stress. 

Results: Of 622 responses, 580 were included in the final analysis. Stress level and prevalence were relatively low (hypo-stress=30.17%, normal stress=49.31%). However, the impact of COVID-19 related issues on stress demonstrated a median score of 5.00-8.00 out of 10. The main factors associated with higher stress levels were being a Christian, accepting emergencies during the pandemic, facing increased living expenses, and having a negative cash flow. In contrast, factors associated with lower stress levels were older age, working within certain specialist domains, and having a positive cash flow. 

Conclusion: This study revealed low stress prevalence and level among Thai dentists during COVID-19 lockdown. Age, religion, specialty, working status, and change in expenses and cash flow during the COVID-19 pandemic were identified as stress predictors.

Advanced Oxidation Processes for the Degradation of Organochlorine Pesticides
Authors: Gandhi Kavita , Khan Noor , Singh Kanchan , Thacker Neeta
Published: April 2023

Advanced Oxidation Processes (AOPs) are a group of treatment technologies, which aim at efficient decomposition of pollutants. The AOPs are based on oxidation of pollutants using various single or combinational techniques generating free radicals, thereby leading to oxidative degradation and complete mineralization of pollutants. Conventional AOPs based on ultraviolet (UV) irradiation are commonly used for destruction of microorganisms in the household filters. These techniques have also been used to remediate conventional and upcoming pollutants like pesticides, Pharmaceuticals etc., which are normally persistent in nature. The various combinations used for generating reactive radicals in AOPs are fenton, photofenton, ozone, UV radiations, sonolysis etc. In the present study, degradation using various AOPs and different pesticides was performed for the organochlorine group of pesticides. It was found to be effective for degradation of the targeted pesticides which are otherwise, persistent in nature. The response of the studied pesticides was different for all the AOPs used, which include, UV photolysis, H2O2 degradation, UV-H2O2, fenton’s etc. Studies have been performed in the aqueous matrix and degradation rates are determined for the different reactions. The rate of degradation was found to be significantly enhanced in presence of H2O2 and fenton’s reagent with UV irradiation rather than UV alone.
URBAN SPEECH AS AN OBJECT OF LINGUISTIC RESEARCH: WRITTEN AND SPOKEN VARIETIES
Authors: Petrov A.V. , Timofeeva N.Y. , Chepurina I.V.
Published: April 2023

The article focuses on methodological tendences in urban language research. Authors, meanwhile, substantiate rationality of its spoken and written varieties as separate fields of study. These studies are marked with a high rate of activity and they highlight a new concept of the «regiolect» — a regional variety of the national language. The analysis of the scientific results of linguo-urbanistics reveals the dominance of the onomastic vector and obvious lack of research into urban speech. The authors specify discrepancies in the function of written and spoken language in linguistic, semiotic and psychological aspects. They also state destructive results of simple mechanical transfer of oral speech techniques to urban epigraphy, the differences between word-formation processes in written and oral speech are described. The visuality of a written sign, the possibility of hybrid word formation with the help of other symbolic and graphic systems, as well as the activity of language norms are listed as features of written communication. A distinctive feature of the oral form is the possibility of meaning explication through non-verbal signs. According to the authors, greater reliability of scientific results in the field of modern urban studies can be achieved through compliance with the principle of unmixed study of living speech and urban writing.
LANGUAGE MARKERS OF TERRORIST-COLORED TEXT AND METHODS FOR THEIR IDENTIFICATION
Authors: Zavarzina G.A.
Published: April 2023

A terrorist-­colored text (T-text) can be understood as a piece of speech containing specific linguistic elements denoting a terrorist threat, according to the features of which it is possible to identify not only the socially dangerous content of the utterance, but also to evaluate the degree of its impact. The archive of the dataset of the extremist website “Kavkaz” banned in the Russian Federation, which contains several thousand links to various topics, served as the material for analysis. A comprehensive method of analyzing T-texts was proposed, aimed at detecting, identifying and distributing T-information over the danger scale: a method of level analysis of language material, in which the text is analyzed as a semantic space formed by linguistic means of different levels, and a method of semasiological analysis of language material, which allows identifying elements of rigid ideologization, due to the terrorist ideology prevailing in the T-space, and unidirectional evaluation, determined by the conformity/ non-conformity of a concept to the basic provisions of the ideology of terrorism. It is concluded that the presented method of linguistic analysis makes it possible to detect verbal signs of a terrorist threat in the discursive space, presented at the explicit and implicit levels, and thus provide a high level of objectivity in linguistic analysis.

Published: April 2023

To develop a sustainable concrete solution, the aggregates and cement in the concrete mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate and biomass ash (sugarcane bagasse ash) respectively. The fresh and hardened properties were studied for three types of mixes (i) the concrete mix with 10-30% replacement of cement with bagasse ash (BA), (ii) Bagasse ash concrete mix with scrap steel fiber and (ii) Bagasse ash concrete with scrap fiber and 10 - 50% coconut shell aggregate. The fresh property of concrete is positively influenced by the addition of bagasse ash. With the addition of scrap fibers and coconut shell the workability reduces by 47% when compared to the control mix. The slump values recorded for all the mixes were within the permissible limit. The density of concrete decreases with the inclusion of bagasse ash and coconut shell which helps reduce the dead weight of structural elements. The mechanical property of concrete increased by 5%, 6% and 8% in compression, split and flexure modes respectively, for 10% bagasse ash steel fiber reinforced concrete. Replacement of gravel with coconut shell affects the strength properties, but all the values were within the permissible limit for structural concrete application. The SEM image analysis showed that the porosity increased with coconut shell content. From the fresh and hardened concrete test results, it was observed that the coconut shell, bagasse ash and scrap fiber can be effectively used as substitutes for concrete ingredients to develop a sustainable fiber reinforced concrete solution.

Authors: Živanović Slavoljub
Published: April 2023

Objective. Panic attack is defined as specific, frightening experience of intense fear and impending catastrophe that is accompanied by numerous somatic symptoms. The scope of study was to show the presentation of panic attack disorder in patients in EMS Belgrade Ambulatory Clinic, its frequency, temporal patterns and prescribed therapy. Methods. The research is a cross-sectional study of the work of a one general practitioner and a gerontology subspecialist from the City institute outpatient clinic in Belgrade EMS, in the period from 18.12. 2014. to 16.01. 2019. in each patient's medical record there was at least one or more complaints recorded. Results. Out of 8398 patients, 61 were found with a diagnosis of panic attack, which is 0.73% of the total number of examined patients. 50.82% were male and 49.18% female, with an average age of 39.92. The most common symptoms were respiratory, as well as numbness and tingling, dizziness, feelings of insecurity and fainting, in 80.3% of cases, patients had somewhat similar symptoms previously, whereas 31.1% presented with an actual panic attack. Of the total number of patients 21.3% of them have already been treated for anxiety and depressive disorder. Ten of them tried to help themselves by taking either bromazepam and diazepam tablets on their own, whereas 35.5% were actually prescribed diazepam by our staff physicians. Conclusion: Panic attack is most often presented as a respiratory manifestation. Patients call for medical assistance somewhat more frequently at nighttime when community healthcare centers are closed, however, this is of no statistical significance. The administered therapy was diazepam orally or intramuscularly.

Objective. The two-dimensional strain is an objective echocardiographic technique allowing the quantification of myocardial deformation. The aim of this study was to specify prognostic contribution of left atrial strain in patients with asymptomatic mitral stenosis. Methods. We included consecutive patients followed for severe or moderately severe rheumatic Mitral Stenosis (MS), asymptomatic, during the period from January 2015 to June 2020 in the Military Hospital of Tunis. The patients followed were divided into two groups according to one criterion of judgment composed of: Cardiac mortality, The occurrence of hospitalization for cardiac reasons, The occurrence of atrial fibrillation (AF), The occurrence of a thromboembolic event, and the need for cardiac surgery or mitral valvuloplasty. Results. Initially eighty patients were selected, but only 53 were followed and then divided into two groups: 30 patients had at least one event and 23 patients had no events according to the occurrence of the major endpoint of the study. In a univariate study and for conventional echocardiographic parameters, we determined that if Left Atrium Area (LAA) is larger than 30 cm 2 and left atrium volume (LAV) more than 100ml/m 2, the risk of occurrence of an event increased significantly respectively (LAA: 69% vs 10%; p = 0.01; OR = 6.6; 95% CI [1.5-28]) and (LAV: 71.4% vs 39%; p = 0.002; OR = 4; 95% CI [1.1-13]). The same was true for left atrium deformation parameters, both Peak Atrial Longitudinal Strain (PALS) <25% and Peak Atrial Contraction Strain (PACS) <10 % were predictive of events in univariate study with the following respective odds ratios (ORs) (PALS: 83% vs 30.4%; p = 0.0001; OR = 11.4; 95% CI [3-42]), and (PACS: 90% vs 47%; p = 0.001; OR = 9.8; 95% CI [2.3-41]). In a multivariate study, the only independent parameter of the occurrence of an event was PACS <10% (p = 0.013; OR = 44; 95% CI [2.19-80]). Conclusion. PACS have prognostic value in asymptomatic MS as it predicts the occurrence of pathologic events in the followup of asymptomatic patients.

Objective. The tobacco usage is a risk factor of the variety oral diseases. To date, the effect of this risk factor on the composition of the oral microbial community has been considered by single studies with unclear pathogenic links. One of the possible factors that could be critical is a severe disturbance microbiota of oral cavity under influence of smoking, so the purpose of the present study was to evaluate the microflora of rats exposed to tobacco cigarette smoke. Methods. We compared the composition of the oral microflora of 20 WAG rats were exposed to smoke of tobacco cigarette and 10 control rats using a culture-based methods targeted at microbial taxonomic and functional profile. Differences between groups were analyzed with nonparametric the Kruskal-Wallis H test. Paired data were analyzed using the Wilcoxon test and Friedman's ANOVA test. Data presented are expressed as mean ± standard deviation (SD) numbers of colony-forming units per ml (CFU/ml). Statistical significance was defined as p<0.05. Results. At the experiment 60th day, comparative analysis of the microbiota showed that microbiological composition varied considerably between the two groups. In the rats influenced by cigarette smoke, exposure time-related reductions in commensal microflora were noted. At the end of the experiment, the commensal bacteria were markedly reduced. In contrast, the opportunistic bacterial diversity was increased and represented by Gram-negative microorganisms as the major phyla. Conclusion. We conclude that alterations in the composition, diversity, and function of the oral microbiome occur in association with tobacco smoke components and exposition term. The established risk factors for oral dysbiosis, especially after long-term exposure may contribute to disease development of the oral cavity.

The investigation was conducted as a cross-sectional study which involved 80 subjects of both gender aged between 18 and 40 years. The data were collected using self-administered survey questionnaire, consisted of 14 closed ended questions related to sociodemographic characteristics and behavioural patterns with benzodiazepines' consumption. Results. More than half of study population confirmed the usage of benzodiazepines (55%). There were statistically significant differences in the duration of drug use so that the most frequent period was 1-5 years (p= 0.025). Study participants claimed that they often used benzodiazepines optionally (43.18%), and in some stressful events (29.56%). The manner of drug supply varied significantly (p= 0.010). The majority of study population applied a drug dose of less than one milligram per day (22.72%), less than 2 milligrams per day in stressful circumstances (25%). The most common way of drug supplying was via prescription (36.36%) and taking it from family members (27.29%%). The analysis of the awareness of possible drug addiction indicated significant differences in attitudes of participants (p < 0.001). Conclusion. A high frequency of Benzodiazepine use with a specific common pattern in consumption requires the improvement of health policy measures in the area of the drug abuse and possible development of addiction.

Authors: Aleksandrić Dejan , Mičeta Lazar , Aleksić Bojana , Dabetić Uroš , Grupković Jovana
Published: April 2023

Introduction: Fractures of the distal end of the clavicle account for 10% - 30% of all fractures of this bone, however, they account for as many as 50% of nonunions and malunions in clavicle fractures. Of all distal clavicle fractures, the highest percentage of complications appertain to Neer type IIB fractures. The aim of this paper is to describe the case of a female patient with a Neer type IIB clavicle fracture treated by fracture reduction and flexible stabilization of the coracoclavicular joint using the TightRope system. Case report: A 48-year-old female patient, injured in a traffic accident while driving a car, suffered a Neer type IIB fracture of the distal edge of the left clavicle. Three days after the injury, the patient underwent indirect stabilization surgery of the coracoclavicular joint by fixation, with the application of the TightRope system. Rehabilitation began on the first postoperative day and was completed three months after surgery, with the achievement of full range of motion in the left shoulder, return of muscle tone and strength of the shoulder muscles, followed by a return to everyday life and work activities, as before the injury. Conclusion: Although no gold standard exists in the operative treatment of the above-described injuries, the indirect method of stabilization and flexible fixation of the coracoclavicular joint, using different types of sutures, achieves good to excellent results. Comparing this method with other described techniques indicates that it has a better functional result, which is achieved faster with a lower complication rate. Our patient's functional results contribute to literature data and yet again demonstrate the effectiveness of this type of treatment for these complex injuries.

Sepsis is a significant health problem, considering that, annually, over 20 million people fall ill from sepsis. Despite the significant development of medicine in recent decades, the mortality rate of sepsis is exceptionally high (about 26%). The definition of sepsis developed together with the understanding of the mechanism of sepsis. At the beginning of the 1990s, the first definition of sepsis was created, according to which sepsis was defined as systemic inflammatory response syndrome (SIRS), with the presence of suspicion or evidence of infection. Due to many inadequately diagnosed patients with sepsis, another definition was created, according to which sepsis is defined as a clinical syndrome. As the result of the lack of clarity of the previous definitions and the new information on the pathophysiological process of sepsis, a third definition of sepsis was developed in 2016. According to this definition, sepsis is a life-threatening condition based on organic dysfunction resulting from the body's inappropriate response to infection. Septic shock manifests as circulatory, cellular and metabolic instability. It is characterized by a serum lactate level higher than 2 mmol/l and hypotension, which requires vasopressor therapy after the administration of intravenous solutions. This definition of sepsis and septic shock enables early recognition and treatment of patients with sepsis, which are critical steps in reducing the incidence and mortality from this disease.

Published: April 2023

Introduction: Sleep quality deterioration and depressive mood are common in patients with multiple sclerosis (MS). The pattern of sleep can be changed due to many psychological and physical symptoms, as well as sociodemographic characteristics occurring within MS. Aim: The study aim was to examine the frequency of changes in sleep quality, depression, anxiety and stress, in MS patients, using the following screening tools: the Pittsburgh Sleep Quality Index - PSQI test and the Depression, Anxiety, and Stress Scale - DASS test, whilst taking into account socio-demographic features, disease duration, as well as the score on the Expanded Disability Status Scale - EDSS score. The aim was also to determine the association between the global PSQI score and socio-demographic characteristics, the EDSS score and illness duration, as well as to examine the relation between the global PSQI score and the DASS subscores. Materials and Methods: The study involved 53 patients, aged 19 - 56, with relapsing-remitting MS, treated with interferon beta. The PSQI index, which evaluates sleep quality, the DASS scale for assessing depression, anxiety, and stress, as well as the EDSS score, which evaluates the severity of the disease, were used. The data was interpreted in the SPSS (Statistical Package for the Social Sciences) statistical program (standard statistical methods, bivariate correlation, linear regression). Results: Sleep quality disorder was present in 44.4% of the examined sample. A positive correlation between the PSQI score and the DASS scale subcscores was established, and linear bivariate regression showed depression (p = 0.001), anxiety (p < 0.001), and stress (p <0.001) to be predictors of the deterioration of sleep quality. A statistically significant correlation between the age of the subjects and sleep quality was determined (p = 0.047). Conclusion: In MS patients with the relapsing-remitting form of the disease, who are treated with immunomodulatory therapy, a significant association between sleep quality and depression, anxiety, and stress, was detected. Of the sociodemographic characteristics, the only established association was the relation between age structure and sleep quality, measured with the PSQI index.

Authors: Subramani Murugan
Published: April 2023

Yellow oleander (Thevetia peruviana), which belongs to the Apocyanaceae family, is a common shrub seen throughout the tropics. All parts of the plant contain high concentrations of cardiac glycosides, which are toxic to cardiac muscle and the autonomic nervous system. The main objective of this study was to socio-clinical, biochemical and electrocardiographic changes of yellow oleander seed poisoning. This prospective observational study was conducted over a period of 6 months (March 2022 to September 2022). Oleander seed poison in most prevalent in the 21–40 years age. More the crushed seeds consumed and the delay to admission to the hospital for treatment poorer was the outcome. The most common GI symptoms of yellow oleander poisoning were vomiting (58 %), abdominal pain (28%), diarrhoea (9%), and palpitations (20%), dizziness (18%).Serum potassium levels that were measured during the admission were directly related to the ECG changes. ECG changes were more observed with patients those who consumed seeds in crushed form and this difference is statistically significant (P = 0.0001). Higher incidence of cardiotoxicity was noted with patients those who consumed poison on empty stomach compare to who consumed after food. The Electrocardiographic manifestations was found even with consumption of one seed, number of seeds consumptions independent of cardiotoxicity.Additonally higher mean Potassium value observed in patients who had cardiotoxicity when compared to patient who had no cardiotoxicity. Death of the patients in yellow oleander seed poisoning was independent of quantity of the seeds they have ingested.

The subject is international legal acts regulating relations in the field of cybersecurity, materials and publications in the field of information security, Internet resources on the problems of this topic.  In the course of the research, the author concludes that today the dynamics of competitive relations in Russia are determined by a number of factors that should be developed at the sites of the SCO, BRICS, CSTO, CIS and other interstate regional associations for the growth of the interconnection of market participants, the integration of production, leveling sanctions costs. These conditions pose the task of finding legal means aimed at enhancing the development of the economic sphere and ensuring security in the information sphere. This poses the task of forming an effective mechanism of technical regulation. At a time when the Russian Federation has significant prerequisites for the breakthrough development of digital technologies as a driver of its economic growth, adequate legal solutions are needed to eliminate existing obstacles on this path.
Enhanced reptile search optimization with convolutional autoencoder for soil nutrient classification model
Authors: Raman Prabavathi , Chelliah Balika J.
Published: April 2023

Background

Soil nutrients play an important role in soil fertility and other environmental factors. Soil testing is an effective tool for evaluating soil nutrient levels and calculating the appropriate quantitative of soil nutrients based on fertility and crop requirements. Because traditional soil nutrient testing models are impractical for real-time applications, efficient soil nutrient and potential hydrogen (pH) prediction models are required to improve overall crop productivity. Soil testing is an effective method to evaluate the presence of nutrient status of soil and assists in determining appropriate nutrient quantity.

Methods

Various machine learning (ML) models proposed, predict the soil nutrients, soil type, and soil moisture. To assess the significant soil nutrient content, this study develops an enhanced reptile search optimization with convolutional autoencoder (ERSOCAE-SNC) model for classifying and predicting the fertility indices. The model majorly focuses on the soil test reports. For classification, CAE model is applied which accurately determines the nutrient levels such as phosphorus (P), available potassium (K), organic carbon (OC), boron (B) and soil pH level. Since the trial-and-error method for hyperparameter tuning of CAE model is a tedious and erroneous process, the ERSO algorithm has been utilized which in turn enhances the classification performance. Besides, the ERSO algorithm is derived by incorporating the chaotic concepts into the RSO algorithm.

Results

Finally, the influence of the ERSOCAE-SNC model is examined using a series of simulations. The ERSOCAE-SNC model reported best results over other approaches and produces an accuracy of 98.99% for soil nutrients and 99.12% for soil pH. The model developed for the ML decision systems will help the Tamil Nadu government to manage the problems in soil nutrient deficiency and improve the soil health and environmental quality. Also reduces the input expenditures of fertilizers and saves time of soil experts.
Evaluating the psychometric properties of the Chronic Time Pressure Inventory using Rasch analysis

Published: April 2023

Background

Chronic time pressure is a common source of everyday stress and anxiety. Noting this, the Chronic Time Pressure Inventory (CTPI) was designed to measure the construct within general samples. The CTPI was validated using procedures informed by classical test theory. This identified a bifactor solution, comprising a general factor encompassing two overlapping factors: Cognitive Awareness of Time Shortage and Feeling Harried. Furthermore, the CTPI demonstrated good psychometric integrity. Explicitly, internal consistency, satisfactory convergent validity with the Perceived Stress Scale, and measurement invariance. While these outcomes indicated that the CTPI was an effective measure of chronic time pressure, the scale was not subjected to analysis of item-person functioning (i.e., Rasch evaluation).

Methods

This study accordingly examined the psychometric properties of the CTPI using Rasch analysis. A general sample of 748 (595 females, 153 males) participants completed the measure online.

Results

Initial findings recommended modification of the response scale. Subsequent analyses revealed unidimensionality, adequate item/person reliability, and gender invariance. Overall, findings confirmed that the CTPI was a valid instrument for assessing perceptions of chronic time pressure within general population samples. Noting the lack of items aligning with higher ability levels, future work should develop the CTPI by adding more complex positively keyed items.

El Convento San Francisco de Alameda demuestra ser un edificio que, a pesar de ser pensado sólo para albergar a los hermanos franciscanos, hoy expone una coexistencia de programas de diversa índole dentro del claustro en torno al patio central. Seis actores son parte de una coreografía compleja que es organizada por mediadores compuestos de elementos arquitectónicos emplazados dentro del edificio con el objetivo de mantener el ambiente interior del claustro. ¿Qué hay de la arquitectura de los mediadores que ha logrado contener programas de diversos indoles en un edificio ensimismado como lo es un claustro?¿Cómo estos mediadores encontrados pueden lograr articular una relación de sus espacios con lo público fuera del edificio? Estos mediadores existen y son producto de todas las intervenciones que han sucedido a lo largo del tiempo dentro del edificio. Es posible identificar cada uno de estos, para luego dibujarlos y analizarlos con el objetivo de aprender qué es lo que hace y para qué. El aprendizaje puede ser trasladado a situaciones aún más complejas que las del claustro, donde exista una mayor fricción entre todos los actores. Por lo tanto, el proyecto especula el potencial de trasladar los mediadores hallados desde su condición original del centro de Santiago, para posicionarlos en una trama de ciudad distinta, cómo lo son las periferias de la ciudad, específicamente el paradero 14 dentro de la comuna de La Florida. Este lugar representa la cultura de la dispersión, que ha surgido por el crecimiento de la ciudad en base a los medios de transporte, generando que en ciertos puntos haya un mayor flujo de gente, haciendo que se posicionen programas de diversa íindole que tengan que coexistir entre ellos de manera forzada en gran parte de las veces. Por lo que el proyecto busca poner a prueba la capacidad de los elementos en cuestión al situarlos en puntos de congestión programática, con el fin de controlar los movimientos y encuentros entre ellos. Junto con esto, los mediadores también buscan generar un espacio interior donde todos los actores que no sabían que podían estar juntos, puedan reunirse de forma controlada.

Ante las críticas respecto a la presencia de errores en las encuestas sociales y el debate respecto a su idoneidad para la representación de la población, la presente investigación realizó un análisis entre las diferencias existentes entre encuestas y registros administrativos. En concreto, este estudio cuantificó la discrepancia existente entre la Encuesta de Protección Social (EPS) y el Historial Previsional de Afiliados, Pensionados y Fallecidos (HPA) del año 2015 en lo que respecta a los ingresos por pensiones de vejez por edad y anticipada en modalidad de retiro vitalicia. Para cada persona de la muestra se realizó un matching entre la ESP y el HPA (Deterministic Record Linkage). Los principales resultados evidencian una brecha absoluta de $43.124 CLP (media) entre lo declarado en la EPS y lo registrado en HPA respecto a pensiones de vejez por edad y anticipada en modalidad de retiro vitalicia. Los modelos de regresión logística aplicados permiten evidenciar que existen dos factores asociados al sub-reporte de pensiones de vejez en EPS 2015, el primero de ellos es el conocimiento de la Pensión Básica Solidaria (PBS) y el segundo es encontrarse emparejado. En otras palabras, las personas que no conocen la PBS tienden a sub reportar y aquellos que están casados también. Un importante hallazgo fue que ambas fuentes de información no están exentas de errores y omisiones, frente a este escenario se sugiere medir y mejorar continuamente los sistemas de recolección de información ya sean estos encuestas o registros administrativos para de esta manera contar con fuentes de información confiables y completas.

Padrões alimentares são os conjuntos ou grupos de alimentos que são consumidos por uma determinada população, os quais expressam efeitos combinados e sinérgicos na saúde pública. Os diferentes tipos de padrões alimentares podem ser associados ou não às doenças crônicas não transmissíveis (DCNT), entre elas a obesidade. A obesidade leva a um estado inflamatório subclínico que piora ainda mais o quadro e leva a outras comorbidades também associadas às DCNT. Este artigo tem o objetivo de relacionar os padrões alimentares inadequados e seus grupos de alimentos, os quais podem induzir e agravar a obesidade através da liberação de substâncias pró–inflamatórias. Este trabalho tem como metodologia a busca por artigos científicos nas principais bases de dados científicas, usando as palavras-chaves “padrões alimentares”, “obesidade”, “hábitos alimentares” e “inflamação”.

Introduction: Coronavirus Disease-2019 (COVID-19) pandemic was a global emergency in 2019 with multiphasic national lockdowns in most countries. Poor accessibility to travel and disease scare led to major fall in routine children vaccination. Aim: To study the impact of COVID-19 pandemic on routine children immunisation at a tertiary care centre in New Delhi, India. Materials and Methods: This retrospective cross-sectional study was carried out in May and June 2022, by collecting retrospective data from Immunisation Clinic of Paediatric Department of Dr. Ram Manohar Lohia hospital, a tertiary care public hospital from January 2018 to December 2021. The data of routine immunisation was further analysed to know the impact of the COVID-19 pandemic in children from birth to 5 years of age in 2019 i.e., before the lockdown versus the first and second major waves of COVID-19 in 2020 and 2021, respectively. The data was entered in an excel chart and statistical testing was conducted with Statistical Package for the Social Sciences (SPSS) version 27.0. Unpaired t-test of equal variance was used for data analysis and p <0.05 was considered as statistically significant. Results: There was a sharp fall in children receiving routine immunisation during COVID-19 pandemic in 2020(30.5%) and 2021 (24.9%) as compared to PreCOVID-19 period (2019). The overall vaccination coverage was significantly lower (p<0.001) in postlockdown-1 phase (July/Aug 2020; n=521) and postlockdown-2 phase (July/Aug 2021; n=735) in comparison to pre COVID-19 period (July/Aug 2019; n=899). Significant fall in vaccination (p<0.05) was seen in postlockdown phase 1 for birth dose vaccines, primary doses of combination vaccines, Measles-Rubella (MR-1) vaccine 1st dose, MR-2 and booster doses of Diphtheria, Pertussis, Tetanus (DPT) and for primary doses of combination vaccines, MR-1 vaccine 1st dose, MR-2 for postlockdown phase 2 (p<0.05). Conclusion: Routine immunisation for all vaccines had a major setback during unlockdown period in 2020 and 2021. There is an urge for national drive for routine Vaccine Preventable Diseases (VPD) to prevent their re-surgence.

Introduction: Coronavirus Disease-2019 (COVID-19) infection in pregnant women can have important effects on the perinatal and neonatal outcomes. Multiple modes of transmission of infection from mother to the newborn have been suggested as also the increased risk of complications in COVID-19 infected neonates. Aim: To study the clinico-epidemiological characteristics and short-term outcomes of neonates born to mothers infected with COVID-19 in relation to maternal COVID-19 severity and co-morbidities and to compare the same between COVID-19 infected and non infected neonates. Materials and Methods: This was a retrospective study of 174 neonates born to COVID-19 positive mothers admitted and delivered from 1st August 2020 to 31st October 2020, at Belagavi Institute of Medical Sciences (BIMS), North Karnataka, India. Data was collected from medical records about the clinical and epidemiological characteristics of the mothers and their neonates, symptoms and severity of COVID-19 and their management and short-term outcomes. Pearson’s Chi-square or Fisher’s-exact test was used for statistical analysis. The p-value of less than 0.05 was considered statistically significant. Results: Out of 174, 18 (10.35%) neonates tested positive for COVID-19 by Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The rates of pre-maturity and low birth weight amongst all 174 neonates were 17.24% and 24.14%, respectively. There were no significant differences in demographic features, in the need for resuscitation and incidence of complications like prematurity, low birth weight, birth asphyxia, meconium aspiration syndrome, sepsis between COVID-19 infected and non infected neonates. However, an increased risk of Early Onset Sepsis (EOS) (OR– 2.21) in COVID-19 infected neonates. None of the COVID- 19 infected neonates required Continuous Positive Airway Pressure (CPAP) or mechanical ventilation and all were discharged subsequently. In this study there were 3(1.72%) deaths, all among COVID-19 non infected, neonates. Conclusion: The incidence of COVID-19 infection in neonates born to COVID-19 infected mothers in this study was 10.35%. Most of the infections in neonates were of less severity without a significantly increased need for respiratory support and without significant mortality.

Introduction: Perinatal Asphyxia (PA) causes impaired exchange of ventilatory gases, or ischemia that leads to persistent decrease in oxygen levels (hypoxemia) and increase in carbon dioxide levels (hypercarbia). It occurs during the peripartum period can contribute to early neonatal mortality and morbidity. Aim: To assess the role of early changes in cranial ultrasound a predictor of outcome in babes with PA. Materials and Methods: This prospective cohort study was conducted in a tertiary care neonatal unit in Maharani Laxmi Bai Medical College, Jhansi, Uttar Pradesh, India, from July 2018 to October 2019. A total of 50 neonates with PA were studied. Cranial ultrasound was performed at or after seven days of life. Neurodevelopment assessment of the subjects were done at 3, 6, 9 and 12 months of life using Development Quotient (DQ). Variables were analysed by student’s t-test and categorical variables were analysed by Fisher’s-exact probability test using graph pad software. Results: Out of 50 infants of PA, 29 had an abnormal ultrasound scan and 21 had normal ultrasound scan. A 16/29 patients had abnormal outcome along with abnormal ultrasound scan while rest of the 13 had normal outcome. The mean DQ of the neonates having abnormal ultra sonographic examination was significantly lower as compared to those with normal examination. A 6 out of 21 neonates had abnormal outcome inspite of having normal ultrasound scan. Cranial ultrasound has a specificity=55%, sensitivity=73%, Positive Predictive Value (PPV)=58% and Negative Predictive Value (NPV)=71% in predicting neurodevelopment outcome of patients with birth asphyxia. Conclusion: Cranial Utrasonography (USG) findings in PA babies reveal a strong association with the development severity.
