Computed Tomography (CT) chest plays a critical role in early identification & stratification of disease burden and prognostication of COVID-19 disease. We compared in-house created CT based scoring system based on ground glass opacities (G-Score), consolidation (C- Score), and atelectasis A-score (i.e. GCA score) with contemporary CT severity scores & validated it against world health organization (WHO) COVID-19 disease severity scale. Patients confirmed with real time polymerase chain reaction confirmed COVID-19 infections that underwent CT chest investigations as a part of standard of care were recruited. A compound GCA score based on the lung involvement was developed and validated. Five-hundred patients of which 249 had mild, 220 with moderate, and 31 with severe COVID-19 disease were recruited.Most involved segments were superior (65%), lateral basal (56%) and posterior basal segments (64%) of right lower lobe and anteromedial (62%) and posterior basal segments (57%) of left lower lobe.Patchy non-confluent peripheral ground-glass opacities with apicobasal gradient is the most common finding (47%) in mild cases. Bilateral lower lobes were most commonly involved (72%).In moderate cases ground-glass opacities with consolidation is the predominant finding (82%).In severe cases ground-glass opacity, consolidation as well as linear platelike atelectasis and reticular opacities may represent with apicobasal gradient (80%).HRCT Chest has certainly come up as a versatile aid for our war against COVID -19. Firstly it helps to diagnose the pulmonary involvement of the disease and when complimented with a good scoring system furthermore it stratifies the disease burden.

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. It is linked to genetic and environmental factors such as nutrition. Insulin resistance (IR) is one of the major pathological changes in PCOS. This study aimed to determine the relationship between IR and macronutrient intake in PCOS subgroups.
Methods: This case-control study was performed on 151 women with PCOS and were divided into four groups according to the Rotterdam diagnostic criteria: A=41, B=33, C=40, and D=37, and 31 women were also in the control group and did not have this syndrome. All macronutrients were assessed with a 168-item food frequency questionnaire (FFQ).
Results: There was a significant relationship between HOMA-IR and some dietary components (Increased calorie in group A, increased total fat intake in group C, lower intake of unsaturated fats (PUFA and MUFA) in group D and higher intake of saturated fat (SFA) and protein intake in the control group). There was no correlation in subgroup B (ovulatory phenotype).
Conclusion: Due to the significant relationship between IR and some dietary components in PCOS subtypes, it is recommended to maintain a balance in carbohydrate and fatty acids intake, and increase dietary fiber to improve health parameters in PCOS subjects.

Published: May 2023

Background: Carnitine is necessary for allowing the long-chain fatty acids to pass the inner mitochondrial membrane to induce β -oxidation. Lack of carnitine and abnormalities of mitochondria play an important role in forming fatty deposition in the liver, and hence, developing steatohepatitis. Carnitine and acylcarnitine identified in human erythrocytes and intra-erythrocyte acetylcarnitine have a significant relationship with the plasma levels.
Methods: The present study was conducted to investigate the possible effects of L-carnitine on liver function, folate and vitamin B12 levels in patients with type 2 diabetes mellitus (T2DM). In this study, 70 patients with T2DM were randomly assigned to either a L-carnitine (CG) and a placebo group (PG). For 12 weeks, the first group received 1000 mg/d oral L-carnitine, whereas the second group received 1000 mg/day wheat starch as placebo. The alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), folate, Vitamin B12, complete blood count (CBC) including blood cells and indicators related to anemia were assessed at baseline.
Results: 64 patients managed to complete the study (32 in each group). The results indicated that consumption of L-carnitine compared with placebo had no significant effect on liver enzymes, folate, vitamin B12, and CBC with differential.
Conclusions: Daily intake of 1000 mg L-carnitine for 12 weeks had no effect on liver function and anemia indicators including CBC, folate, and vitamins B12.

Published: May 2023

Background: The current systematic review was conducted to investigate the effects of vitamin D supplementation on vitamin D levels, bone health, and physical performance indices in adults with spinal cord injury (SCI).
Methods: The PubMed, Scopus, Web of Science, and Embase databases were searched for studies published up to June 2020, with no language limits. To determine the risk of bias, the Academy of Nutrition and Dietetics Quality criteria checklist was used.
Results: Eight studies that met all of the inclusion criteria were identified. All of the eligible studies had a high level of heterogeneity regarding outcome measures, study design, and the dose of vitamin D. The majority of the trials showed beneficial effects of vitamin D supplementation on serum vitamin D levels and other outcome measures in patients with SCI. Three randomized controlled trials revealed a low risk of bias, whilst other studies were rated as the either neutral or negative risk of bias.
Conclusion: This review suggests that vitamin D supplementation could improve vitamin D levels, bone health, and physical performance indices in individuals with SCI. However, due to the high level of heterogeneity, the results should be interpreted with caution. Further studies on this population should be performed to have sufficient power and a robust design to give definitive conclusions.

Compte tenu de l’importance socioéconomique et alimentaire du riz, les producteurs ont utilisé plusieurs systèmes de culture pour mieux assurer la compétitivité de leurs exploitations. La présente étude a consisté en une analyse de l’efficacité économique des systèmes de culture du riz en bas-fonds. Un échantillon de 283 producteurs a été constitué de façon aléatoire. L’approche stochastique des frontières de production et de coût a permis d’estimer et de décomposer l’efficacité économique en ces deux composantes (efficacité technique et efficacité allocative). Les analyses ont été faites à l’aide du logiciel d’analyse STATA 14.1. Les résultats ont montré que les efficacités diffèrent d’un cycle de production à l’autre et d’un système de culture à l’autre. Le système de culture impliquant plus les pratiques d’une transition agroécologique (SCR2) a été plus efficace en production pluviale 0,39 (±0,01) et en décrue 0,41 (±0,07) alors que le système impliquant moins les pratiques d’une transition agroécologique (SCR1) a été plus efficace en production de contre saison 0,68 (±0,09) face aux autres systèmes. Le renforcement du dispositif d’accompagnement des producteurs pouvait leur permet de mieux assurer la compétitivité de leurs exploitations à travers le choix d’un système de culture plus efficace.

Given the socioeconomic and nutritional importance of rice, farmers have used several cropping systems to better ensure the competitiveness of their farms. This study consisted of an analysis of the economic efficiency of lowland rice cultivation systems. A sample of 283 farmers was randomly selected. The stochastic approach of production and cost frontiers made it possible to estimate and break down economic efficiency into these two components (technical efficiency and allocative efficiency). Analyzes were performed using STATA 14.1 analysis software. The results showed that the efficiencies differ from one production cycle to another and from one cropping system to another. The cropping system involving more agroecological transition practices (SCR2) was more efficient in rainfed production 0.39 (±0.01) and in flood recession 0.41 (±0.07) while the system involving less agroecological transition practices (SCR1) was more effective in off-season production 0.68 (±0.09) compared to other systems. Strengthening the support system for farmers could enable them to better ensure the competitiveness of their farms through the choice of a more efficient cropping system.

La consommation du manioc, sous forme des pâtes alimentaires (Foufou ou chikwangue) nécessite de passer par le rouissage qui réduit la toxicité due à la présence de l’acide cyanhydrique. Cependant, les caractéristiques des exploitations et les techniques de rouissages sont variées. Ainsi l’objectif de cette étude était de réaliser une typologie des exploitations agricoles familiales de la commune de Maluku, en rapport avec les techniques de rouissage du manioc. Une enquête portant sur 344 exploitations agricoles a permis de collecter les données y afférentes. Les caractéristiques sociodémographiques, les caractéristiques de l’exploitation, les contraintes auxquelles font face les exploitations ainsi que la localisation (villages) ont été prises en compte. La typologie a été réalisée sur base de l’Analyse en Composantes Multiples (ACM) et la Classification Hiérarchique Ascendante (CHA). Les résultats révèlent 3 types d’exploitations agricoles. Le premier axe principal est dominé par le village, le type de contraintes, la productivité en cosette, le type de la main-d’œuvre et le type de matériel végétal. Le second axe principal est dominé par les techniques de rouissage.

The objective of this study is to develop a typology of cassava-producing farms in the Maluku area, on the outskirts of Kinshasa in the Democratic Republic of Congo. The criteria chosen are: socio-economic characteristics (type of workforce, membership of a group of producers and type of production constraints); characteristics related to cassava production technology (exploited area, plowing equipment and type of plant material); the characteristics linked to the cassava processing technology (retting method, retting duration and chip yield) and the village. The data was collected by survey on 344 farms operating in 6 villages. The typology was made thanks to an ACM and finalized by a CAH. The results of the study made it possible to group cassava producers into three types on the basis of the variables retained. The results reveal 3 types of farms. With the village, the type of constraints, the productivity in cosette, the type of labor and the type of plant material as the dominant characteristics of the first axis of the typology and the mode and duration of retting as the dominant characteristics of the second axis.

La troponine T ultra-sensible (us), marqueur biologique spécifique du cœur, peut être élevée dans des conditions pathologiques autres que le syndrome coronarien aigu. Ces autres causes peuvent ou non être directement liées aux maladies cardiaques. Nous rapportons le cas d'une patiente de 85 ans présentant de multiples événements cardiovasculaires qui présentait une élévation de la troponine T us à 1088 pg/ml, probablement due à de multiples étiologies.

Landslide Soil Failure Parameters Characterization Using Geoelectrical Resistivity Methods in Uruagu, Nnewi, Anambra State, Nigeria
Authors: Uwaezuoke Charles Chinedu , Airen Osariere John 
Published: May 2023

Electrical Resistivity Imaging (ERI) and Vertical Electrical Sounding (VES) were deployed over the Uruagu landslide area. The main purpose of the study was to characterize the landslide failure parameters in to identify the soil failure mechanisms. Ten profiles of 2D ERI measuring 200 m each, and thirty VES, with three VES along each profile, were executed. Nine of the ten profiles were executed within the landslide site while one profile was executed in a residential street as a control profile. Four soil samples were also taken for physical and geotechnical laboratory index analysis. The PASI resistivity meter was used for the geoelectrical resistivity measurements. The Wenner-Schlumberger array was deployed for the ERI with a minimum electrode spacing of 10 m. The Schlumberger array was deployed for the VES with a maximum current spacing of 130 m. ERI resistivity data analysis involved inversion using the RES2DINV software package involving mean model residual and construction of iso-apparent resistivity contour maps. VES resistivity data analysis involved calculated parameters from plotted field data on a log-log graph then used as initial models in an iterative forward modeling WinResist software package. The results of the ERI and VES for the control profile reveal that the subsurface strata are originally composed of silty clay of resistivity values (16.7 – 60.9) Ωm, clayey silty sand having resistivity values (116 – 800) Ωm and sandstone layer with resistivity values (>814 Ωm). The ERI and VES results for the devastated landslide site reveal counteraction material of resistivity values (>814 Ωm), colluvia and regoliths (116 - 300 Ωm), and variably wet weathered sandstones of resistivity values (<60.9 Ωm). The laboratory results revealed the landslide site is majorly composed of silty sandy clay, silty clay, sandy silty clay, and sandstones as the pre-landslide existing lithologies. The natural water content ranges from 10.6% to 14.0%. The liquid limit ranges from 44.0% to 46.0%, the plastic limit ranges from 15.0% to 17.0%, and the plasticity index from 28.0% to 29.1%. The geophysical and laboratory results revealed consistency in the lithological units in agreement with the characteristic geology of the study area. The landslide site has high gully slope gradients and collects a large volume of floods during the intense rainy season. These soils, during the intense rainfall, imbibe more water, following their high plasticity slide along the sandstone to activate the soil failure.

Dans le but de contribuer de façon durable à la sécurité alimentaire des ménages, cinq (05) grandes familles de pratiques agro-écologiques (Gestion Intégrée de l’Agriculture et de l’Elevage (GIAE), Gestion Intégrée de la Fertilité des Sols (GIFS), Agro-Foresterie (AF), Conservation des Eaux et du Sol (CES), Agriculture de Conservation (AC)) ont été introduites, depuis les années 90, dans les zones cotonnières au Bénin. Trente ans après leur introduction, il importe d’identifier les grandes familles de pratiques agro-écologiques réellement adoptées par les producteurs. Ainsi, à travers un questionnaire semi-structuré, les données ont été collectées auprès de 300 producteurs de coton choisis au hasard et répartis dans trois communes (Banikoara, Sinendé et Djidja) représentatives des trois zones cotonnières (haut nord, centre-nord et sud) du Bénin. Une Analyse Factorielle des Correspondantes (AFC) a été réalisée avec le logiciel R i386 4.0.4. Les résultats de l’AFC montrent que, sur les cinq (05) grandes familles de pratiques agro-écologiques introduites dans les zones cotonnières au Bénin, trois (03) grandes familles ((GIFS), (GIAE) et (AF)) ont été fortement adoptées. Par contre, les pratiques de la grande famille du CES ont été marginalement adoptées et celles de l’AC n’ont pas du tout été adoptées dans ces zones.

In order to contribute in a sustainable way to household food security, five (05) major families of agro-ecological practices (Integrated Management of Agriculture and Livestock (GIAE), Integrated Management of Soil Fertility (GIFS), Agro-Forestry (AF), Water and Soil Conservation (CES), Conservation Agriculture (CA)) have been introduced since the 1990s in the cotton-growing areas of Benin. Thirty years after their introduction, it is important to identify the main families of agro-ecological practices actually adopted by producers. Thus, through a semi-structured questionnaire, data were collected from 300 cotton producers chosen at random and distributed in three communes (Banikoara, Sinendé and Djidja) representative of the three cotton-growing areas (upper north, center-north and south ) from Benin. A Corresponding Factor Analysis (FCA) was performed with R i386 4.0.4 software. The results of the AFC show that, out of the five (05) large families of agro-ecological practices introduced in cotton-growing areas in Benin, three (03) large families ((GIFS), (GIAE) and (AF)) have been strongly adopted. On the other hand, the practices of the large SWH family have been marginally adopted and those of CA have not been adopted at all in these areas.

La présente étude examine la relation entre la charge de travail, le soutien social et le bien-être psychologique au travail. L’échantillon est composé de 180 agents de santé âgés de 21 à 52 ans dont 41 Médecins, 113 Infirmiers/Sages-femmes et 26 Aides-Soignants. Les données sont collectées à partir d’un questionnaire incluant les échelles de la charge de travail, du soutien social et du bien-être psychologique au travail ainsi qu’un guide d’entretien semi-directif, et analysées à l’aide de l’analyse de variances (ANOVA). Les résultats indiquent, d’une part, qu’il n’existe pas de différence significative entre la charge de travail et le bien-être psychologique des participants. D’autre part, le soutien social ainsi que son interaction avec la charge de travail ont un effet positivement significatif sur le bien-être psychologique au travail des agents de santé des services de pédiatrie des CHU d’Abidjan. Ces résultats suggèrent aux dirigeants des structures sanitaires de promouvoir le travail en équipe des agents de santé afin de favoriser leur bien-être psychologique au travail gage de la qualité de l’offre de soins.

This study examines the relationship between workload, social support and psychological well-being at work. The sample is composed of 180 health workers aged between 21 and 52 years, including 41 doctors, 113 nurses/midwives and 26 nurses' aides. The data were collected using a questionnaire including workload, social support and psychological well-being at work scales as well as a semi-directive interview guide, and analysed using analysis of variance (ANOVA). The results indicate, on the one hand, that there is no significant difference between the participants' workload and psychological well-being. On the other hand, social support and its interaction with workload had a significant positive effect on the psychological well-being at work of health workers in the paediatric departments of the Abidjan University Hospital. These results suggest that the managers of health facilities should promote teamwork among health workers in order to foster their psychological well-being at work, which is a guarantee of the quality of the care provided.
ANÁLISE AMBIENTAL DE VEREDAS
Authors: Martins Wagner Lemos 
Published: May 2023

Esse estudo apresenta parte de uma investigação realizada durante o Programa de Mestrado em Geografia da Universidade Federal do Tocantins, Campus de Porto Nacional. A pesquisa trata de uma análise ambiental de Veredas, localizadas no córrego Correntinho, que se encontra inserido no munícipio de Miracema do Tocantins-TO, e teve como objetivo analisar as condições ambientais em que se encontram as Veredas localizadas no curso principal do córrego em questão. Nesse sentido, adotou-se como metodologia a aplicação do Índice de Vegetação por Diferença Normalizada (NDVI), e o Índice de Água por Diferença Normalizada (NDWI). O uso da ferramenta NDVI indicou que a massa de vegetação no curso do córrego Correntinho apresenta-se em vários estágios. Assim, os resultados possibilitam uma compreensão da fitofisionomia das Veredas, permitindo até mesmo teorizar quanto à evolução de estratos na comparação entre dados de diferentes períodos, configurando um importante instrumento de monitoramento ambiental das ações que possam trazer agravos ambientais. Dessa forma, a análise de dados do NDVI e NDWI apresentou-se com grande potencial para o estudo dos ambientes de veredas, além de permitir a teorização quanto a uma compreensão da fitofisionomia das Veredas, que merecem atenção por sua importância para o bioma Cerrado. Nesse sentido, essas geotecnologias são apropriadas para a análise ambiental das Veredas, ao permitir a comparação entre dados de diferentes períodos, e no acompanhamento de ações que possam causar impactos ambientais.
