Relevance. Treatment of chronic acromioclavicular joint dislocations remains a controversial issue and ranges from conservative treatment to extensive reconstruction.
Objective: to compare clinical and radiographic results of surgical treatment of patients with chronic acromioclavicular joint dislocation.
Materials and Methods. A retrospective analysis of 41 patients with chronic acromioclavicular joint dislocation was performed (time from the injury was more than 3 weeks). The patients were divided into two groups: group I (19 patients, 46.3%), which underwent arthroscopically assisted dynamic type of acromioclavicular joint dislocation stabilization with acromioclavicular and coracoclavicular ligaments augmentation, and group II (22 patients, 53.7%), which underwent fixation of acromioclavicular joint dislocation with Hook-plate and acromioclavicular and coracoclavicular ligaments augmentation. The mean age at surgery was 34.1±11.2 years (range 18-70 years). Most of the patients were males – 36 patients (87.8%). Clinical outcomes were assessed using the Oxford Shoulder Score, Constant – Murley Score, and Acromioclavicular Joint Instability Scoring System.
Results. The mean Oxford Shoulder score before surgical treatment was 31.5±7.7 points and 33.3±4.2 points (p=0.347), and at the final follow-up 46±2.6 points and 46.1±1.6 points – in group I and group II, respectively. The mean Constant – Murley score before surgical treatment was 68.9±12.4 points and 69.7±14.5 points (p=0.863), and at the final follow-up 94.2±7.7 points and 96.5±3.9 points (p=0.291). The mean Acromioclavicular Joint Instability Scoring System score before surgical treatment was 31.3±9.5 points and 25.1±8.2 points (p=0.087), and at the final follow-up 79.9±16.7 points and 75.7±9.1 points (p=0.422), respectively. Concomitant intra-articular injuries of the shoulder joint were diagnosed in 68.4% of patients; the most common injuries were SLAP injury and long head of biceps tendonitis. Complications of treatment were noted in both groups, but there were no complications that would require additional reconstructive.
Conclusions. Arthroscopic assisted dynamic fixation techniques or open fixation techniques with a specialized plate in combination with the reconstruction of acromioclavicular ligaments and coracoclavicular ligaments by tendon autografts provides good long-term functional results.

Published: August 2022

Introduction: Many authors in their research have suggested an association between vitamin D and asthma, but the results from these publications are sometimes confusing.
Aim: Our aim was to assess the relationship between serum vitamin D and lung function in patients previously diagnosed with asthma.
Materials and methods: The present study started in September 2019 and was completed in May 2020. All patients were diagnosed at the University Clinical Center-Prishtina, Kosovo. Spirometry was performed on children of ages 6-16 years old with a spirometer according to the recommendations of the American Thoracic Society.
Results: Of the 57 children who visited the University Clinical Center of Kosovo-Department of Pediatrics, 29 were diagnosed with asthma. The Spearman coefficient correlation showed statistical significance between vitamin D and body weight, and vitamin D and FEF75% at level 0.05. Other parameters did not show statistical significance with vitamin D, but such statistical significance was found in other parameters between asthma and healthy groups.
Conclusions: Our data suggested that serum vitamin D level was insignificant for FVC%, FEV1%, Tiffeneau Index values, and PEF. Statistical significance was observed between vitamin D and body weight; vitamin D and FEF75% (p=0.05).

Published: August 2022

As a neurodevelopmental disability, Autism Spectrum Disorder (ASD) is classified as a spectrum disorder. The availability of an automated technology system to classify the ASD trait would have a significant impact on paediatricians, as it would assist them in diagnosing ASD in children using a quantifiable method. In this paper, we propose a novel autism diagnosis method that is based on a hybrid of the deep learning algorithms. This hybrid consists of a convolutional neural network (ConVnet) architecture that merges two LSTM blocks (BiLSTM) with the other direction of propagation to classify the output state on the brain signal data from electroencephalogram (EEG) on individuals; typically development (TD) and autism (ASD) obtained from the Simon Foundation Autism Research Initiative (SFARI) database to classify the output state. For a 70:30 data distribution, an accuracy of 97.7 percent was achieved. Proposed methods outperformed the current state-of-the art in terms of autism classification efficiency and have the potential to make a significant contribution to neuroscience research, as demonstrated by the results.

Background and Objectives: Data with more severe mutations of the SARS-CoV-2 virus, compared with the original wild-type strain of COVID-19 disease, were reported worldwide. The study aims to describe the clinical and laboratory manifestations of a multisystem inflammatory syndrome in children (MIS-C) associated with SARS-CoV-2 in the Republic of Kazakhstan and to compare the severity of the disease depending on the time of the circulating variant of SARS-CoV-2 virus.
Material and methods: A retrospective, multicentre, nationwide study of 89 children with MIS-C who received inpatient treatment from August 1, 2020, to December 1, 2021. The patients were allocated into two groups: 1(2020) - 45 children and 2 (2021) - 44 children. Study periods were characterized by the circulation of different strains of the SARS-CoV-2 virus.
Results: In children with MIS-C in 2021, acute renal failure, disseminated intravascular coagulation syndrome, and shock were statistically more frequently found, which led to fairly common admittance to the intensive care unit. When comparing laboratory data, the children with MIS-C in 2021 had higher values ​​of inflammation markers: ferritin, procalcitonin, erythrocyte sedimentation rate, leukocytes, and neutrophils. Furthermore, these children had a lower level of lymphocytes than children with MIS-C in 2020.
Conclusions: MIS-C is a severe, life-threatening systemic disease characterized by multiple organ damage and important inflammatory changes in laboratory parameters. A more aggressive clinical course of MIS-C in 2021 may be associated with the emergence of new SARS-CoV-2 strains.

ABSTRACT. The consumable palm wine has never been used in heat treatment process of steels. This research therefore focuses on the utilization of the consumable palm wine and other palm tree products as quenchants. The mechanical and physical properties of the samples were also evaluated to determine which of the quenchants that influences the hardness and corrosion rate values of medium carbon steel the most. The corrosion test was performed in 1.0 M of HCl solution and homemade vinegar using potentiodynamic polarization method. The results revealed a hardness value of 431, 351, 359 and 265 HB for the samples quenched in palm wine, palm kernel oil, palm oil and as-received, respectively. The corrosion rates of palm oil tempered samples showed more susceptibity to corrosion in HCl solution with a value of 2.261e+003 mil/year. Vinegar offers the highest corrosion rate with a value of 4.017e+002 mil/year for palm wine tempered. The corrosion rate of the as-received samples pulled the lowest values while on the treated samples, palm kernel oil showed the least corrosion rate values.

Published: August 2022

ABSTRACT. Nano hydroxyapatite (n-HAp) and its composites have shown a great development in the field of tissue regeneration and in controlled drug delivery due to its good biocompatibility and bioactivity behavior. Furthermore, HAp-based nanocomposites enhance mechanical properties. These synthetic HAp nanocomposites can also be tailored to fabricate scaffold with controlled porosity which facilitate the growth of the cell in the field of tissue engineering. In this paper, we focus on the synthesis of nano hydroxyapatite (n-HAp) by sol-gel method. The synthesized nano powders were calcined at 500 oC and characterized by FT-IR, XRD and TEM. We have also described the synthesis of citric acid-based polyester by melt polycondensation method without adding catalyst. The monomers used were citric acid, 1,6-hexane diol and sebacic acid. The corresponding synthesized n-HAp/polyester composite have potential application in soft tissue engineering. The structures of polyester and its nanocomposite were studied by FT-IR and 1H NMR spectral studies. The thermal and mechanical properties of polyester, composites and cytotoxicity activity (MTT assay) using vero cells were also studied. Porous scaffold of the nano HAp/Polyester was fabricated by solvent-casting particulate leaching technique which is useful in the development of tissue engineering applications. SEM and TEM studies were carried out for nano HAp, polyester, composites and scaffold.

Published: August 2022

ABSTRACT. The synthesis of Schiff base compound derived from 2-hydroxy-3-methoxybenzaldehyde and o-phenylenediamine via solvent-assisted mechanochemical synthesis in the presence of a small amount of dimethylformamide as liquid-assisted solvent was reported. The Co(II), Ni(II), Cu(II) and Zn(II) Schiff base complexes were synthesized and characterized by powder x-ray diffraction, infra-red spectroscopy, differential scanning colorimetry, thermogrametric analysis, energy dispersive X-ray analysis and CHNS/O macro-analysis. According to infrared spectral analysis, a strong band in the spectra of Schiff base at 1617 cm-1 was assigned to the azomethine v(C=N) stretching vibration. In the complexes, it shifted to lower frequency regions, indicating the formation of desired compounds. The DSC thermogram of Schiff base showed a single sharp peak at 158 oC, which is attributed to the melting or the phase transition. As revealed by TGA, the complexes were obtained as solid compounds containing some amounts of water molecules. The powder-XRD analysis showed that the patterns of the synthesized compounds were different from the starting materials, indicating that the starting constituents were changed into product. The antimicrobial activity results for selected bacteria and fungi revealed that complexes have higher activity than the Schiff base. Furthermore, the synthesized compounds were found to be more effective against fungal isolates than those of bacteria.

Published: August 2022

Pests have been implicated in causing severe damage to food crops including mushrooms, thereby increasing the incidence of postharvest loss. This study investigated the various pests involved in the cultivation of gamma radiation aided cultivated Pleurotus ostreatus. Pests were isolated and identified by the procedure described by the Entomological Society of Canada. Cultivation of Pleurotus ostreatus was achieved by pre-treating composted sawdust substrates and spawn preparation with a gamma radiation dose of 15 kGy from a Cobalt 60 source (SLL 515, Hungary) at a dose rate of 1.7 kGyh-1 in air. A total of five pests were recorded while cropping, namely; Drosophila melanogaster (Fruit fly), Blatta germanica (cockroach), Archachatina marginata (giant snail), and Doratogonus meridionalis (millipede) and Cryptophlebia leucotreta (False codling moth). The predominant pest was Drosophila melanogaster (Fruit fly) (97%). Results recorded over four flush periods were 378g, 0.63, and 63% for Total yield, biological yield, Biological Efficiency (%), respectively. The average stipe length and pileus diameter were recorded and showed no statistical differences (p>0.05) observed in the different weeks. Other growth parameters (mushroom size, total number of primordia, total number of fruitbodies etc.) recorded showed some significant differences (p<0.05). Pests identified contributed to yield reduction and product quality.

Au Cameroun, les Loranthaceae ont été signalées dans quelques bassins de production du cacao. Cette étude a été menée dans le but de caractériser le parasitisme des cacaoyers de la localité de Tombel, au Sud-Ouest Cameroun. Les observations des Loranthaceae ont porté sur les arbres âgés de 8 à 10 ans, et sur une superficie de 7500 m². Sur chaque pied de cacaoyer, les données suivantes ont été collectées et notés : la circonférence à 1,30 m du sol , la hauteur, le nombre de branches, les espèces de Loranthaceae présentes, et le nombre de touffes des parasites. Au total, quatre espèces de Loranthaceae ont été recensées sur les cacaoyers, Helixanthera mannii étant la plus fréquente. Le taux de parasitisme des plantations était de 35,33% et la densité parasitaire moyenne était de 3±2 touffes/arbre. Les arbres parasités ont montré des circonférences et des hauteurs significativement plus élevées que les arbres sains. Le coefficient de rang de Spearman a montré une corrélation positive et significative entre la hauteur de l’arbre et le nombre de touffes des Loranthaceae. Il s’avère donc nécessaire de mettre en place un programme de contrôle des Loranthaceae dans les plantations afin de réduire les pertes de production, mais également de mener une étude approfondie sur la biologie et l’écologie d’ Helixanthera mannii qui, dans le futur, pourrait s’avérer être une menace pour les cacaoyers.
In Cameroon, Loranthaceae have been reported in some cocoa production basins. This study was conducted to characterise the parasitism of cocoa trees in the locality of Tombel, South-West Cameroon. Observations of Loranthaceae were made on trees 8 to 10 years old, and on an area of 7500 m². On each cocoa tree, the following data were collected and recorded: circumference at 1.30 m from the ground, height, number of branches, Loranthaceae species present, and number of pest clumps. In total, four species of Loranthaceae were recorded on cocoa trees, Helixanthera mannii being the most frequent. The parasitism rate of the plantations was 35.33% and the average parasite density was 3±2 clumps/tree. Parasitised trees showed significantly higher girths and heights than healthy trees. Spearman's rank coefficient showed a significant positive correlation between tree height and the number of Loranthaceae clumps. It is therefore necessary to set up a control programme for Loranthaceae in plantations in order to reduce production losses, but also to carry out an in-depth study on the biology and ecology of Helixanthera mannii, which could prove to be a threat to cocoa trees in the future.

Published: August 2022

La Sardinelle plate est l’un des petits pélagiques côtiers béninois soumis à une forte pression de pêche. Cette étude présente la caractérisation morphologique, le mode de croissance et l’embonpoint de l’espèce. Pendant douze mois, 1026 spécimens de Sardinella maderensis ont été échantillonnés aléatoirement dans les débarquements au port de pêche artisanale de Cotonou. Parmi les différents paramètres biométriques et méristiques relevés sur chaque spécimen, seules la longueur totale et la grande hauteur ont montré une différence significative suivant le sexe (p<0,05). Ainsi, les femelles présentent un corps plus long et plus haut que les mâles signalant l’existence d’un dimorphisme sexuel chez l’espèce. L’analyse factorielle discriminante révèle que le nombre de branchiospines sur les branches supérieure et inférieure du premier arc branchial ainsi que les ratios longueur de la tête sur distance orbitaire, longueur pré-orbitaire sur distance orbitaire et longueur à la fourche sur longueur totale constituent des paramètres discriminants pouvant permettre de caractériser l’espèce suivant les différents stades de vie. La relation âge-longueur indique que la Sardinelle plate développe une croissance allométique rapide dès le bas âge. Les valeurs mensuelles élevées du facteur d’embonpoint attestent d’une bonne adaptation de l’espèce aux conditions écologiques dominantes de son milieu de vie.
The flat Sardinella is one of the small Beninese coastal pelagic species subject to strong fishing pressure. The study aims to carry out morphological characterization, growth model and body condition factor of the species. For twelve months, 1,026 specimens of Sardinella maderensis were randomly sampled in the landings at artisanal fishing port of Cotonou. Among the various biometric and meristic parameters recorded on each specimen, only total length and great body height showed a significant difference according to the sex (p<0.05). Indeed, females have longer and higher body than males, indicating the existence of sexual dimorphism in the species. Discriminant factor analysis reveals that the number of gill rakers on the upper and lower branches of the first gill arch as well as the ratios of head length by orbital distance, pre-orbital length by orbital distance and fork length by total length constitute the discriminating parameters that can be used to characterize the species at different life stages. The age-length relationship indicates that the species develops rapid allometric growth from an early age. The relatively high mean value in the body condition factor attests to the good adaptation of this species to the prevailing ecological conditions of its living environment.
