Reportedly, SARS-CoV-2 infection impairs glucose homeostasis and metabolism. Moreover, hyperglycaemia has emerged as an important risk factor for COVID-19 mortality. A cross-sectional study involving hospitalized patients in Sidi-Bel-Abbes with COVID-19 critical infection regardless of diabetes status was conducted. Data was collected from COVID-19 Registry, including age, sex, and blood sugar level at admission. Out of 800 patients admitted for SARS-CoV-2 with, 332 patients (206 males, 126 females) exhibited hyperglycaemia, which equates to a prevalence of 41,5%. Patients had a median age of 64 years and a median blood sugar of 1,59. Admission hyperglycaemia was not statically associated with age and sex. Blood glucose status is paramount for ensuring safe and effective treatment of inpatients COVID-19. Additional studies are forthcoming to address the study's limitations and to better understand the impact of hyperglycaemia on COVID-19 patients.

Maternal mortality remains public health issue. One of its leading causes is postpartum haemorrhage. The aim of this study is to test the relationship between haemoglobin levels, perineal tear, retained placenta, uterine atony, and maternal mortality from postpartum haemorrhage in Jember district, Indonesia. This case-control study comprised 43 mothers died from postpartum haemorrhage (cases), and 43 mothers survived from postpartum haemorrhage (controls) between from January 2017 and December 2019. Data were obtained from maternal verbal autopsies, complemented by birth registrations and medical records in 26 community health centres across Jember district. The chi-square, and multivariate logistic regression were administered to test the hypothesis. The results of this study indicate that Haemoglobin levels (p = 0.032, OR 6.372, 95% CI 1.172 - 34.626),  retained placenta (p = 0.033, OR 4.578 95% CI 1.128 – 18.587), and atonia utery (p= 0.014, OR 4.578 95% 1.364 – 16.502) had significant relationship with maternal deaths from postpartum haemorrhage. However, perineal tear (p= 0.155, OR 0.347 95% 0.081 – 1.490) had no significant relationship with maternal deaths from postpartum haemorrhage. The conclusion in this study is Identifying obstetric factors are important. Therefore, conducting early detection screening during pregnancy is encouraged to reduce postpartum haemorrhage maternal death.

Published: August 2022

The ability of music to spread joy and excitement across lives, makes it widely acknowledged as the human race's universal language. The phrase "music genre" is frequently used to group several musical styles together as following a shared custom or set of guidelines. According to their unique preferences, people now make playlists based on particular musical genres. Due to the determination and extraction of appropriate audio elements, music genre identification is regarded as a challenging task. Music information retrieval, which extracts meaningful information from music, is one of several real - world applications of machine learning. The objective of this paper is to efficiently categorise songs into various genres based on their attributes using various machine learning approaches. To enhance the outcomes, appropriate feature engineering and data pre-processing techniques have been performed. Finally, using suitable performance assessment measures, the output from each model has been compared. Compared to other machine learning algorithms, Random Forest along with efficient feature selection and hyperparameter tuning has produced better results in classifying music genres.

Authors: Zheng Jiamian , Jiang Xuan , Zhao Haotian , Wang Wandi , Wu Xiuli , Jin Zhenyi
Published: August 2022

Human γδ T cells are unconventional lymphocytes that function in innate and adaptive immune responses and immunosurveillance. These cells show potent cytotoxicity against tumor cells in a major histocompatibility complex unrestricted manner and have recently gained considerable attention as a sparkling star for clinical immunotherapy. Clinical immunotherapy trials with activated γδ T cells are tolerated well. However, clinical benefits are still unsatisfactory. Therefore, anti-tumor effects need to further increase the cytotoxicity of γδ T cells via several mechanisms, including the novel nitrogen-containing bisphosphonate products, adjuvant use with a bispecific antibody and chimeric antigen receptor, co-immunotherapy with γδ T cells plus immune checkpoint inhibitors, and adoptive immunotherapy with Vδ1 T cells and T cells engineered to express a defined γδ T cell receptor. Here, this article describes the crucial role of γδ T cells in anti-tumor immunity, concludes transduction strategies and summarizes the different development of novel approaches for clinical applications and cancer immunotherapy, which may be effective in overcoming current therapeutic limitations.

La Colangiopancreatografía Retrógrada Endoscópica (CPRE) constituye la técnica de elección para el drenaje de la vía biliar, ya sea en casos de obstrucción biliar benigna o maligna. Sin embargo, una vez esta técnica no resulta eficaz o factible, tenemos a nuestra disposición varias alternativas, siendo la más utilizada hasta ahora la colangiografía transhepática percutánea (CTPH). Sin embargo, a día de hoy el drenaje biliar guiado por ecoendoscopia (USE-BD) constituye una alternativa cada vez más factible a la radiología intervencionista o la cirugía. En esta revisión se abordarán los resultados de este tipo de drenaje en comparación con los demás, así como los diferentes tipos de técnicas disponibles y sus resultados en la práctica clínica.

Authors: Turnes Valerio , Cazella Ademir Antonio , Pecqueur Bernard , Guzzatti Thaise Costa
Published: August 2022

O enfoque da Cesta de Bens e Serviços Territoriais (CBST) completou vinte anos desde que dois artigos pioneiros sobre o tema foram publicados, em 2001, na revista francesa “Economie Rurale”. A ideia central dessa abordagem está associada à oferta compartilhada de produtos e serviços de qualidade de um determinado território. Sua concepção se deu a partir de estudos de caso em zonas francesas de montanha, onde o modelo de agricultura produtivista não se difundiu de forma plena. A construção de um painel de indicadores dos principais componentes da CBST se tornou necessária a partir da utilização do enfoque para estudar distintos territórios. O objetivo deste artigo consiste em conceber uma ferramenta metodológica de monitoramento que seja capaz de averiguar a aproximação entre a realidade constatada em determinado território e o tipo ideal de Cesta. Esses indicadores podem ser utilizados tanto para fins específicos de pesquisa, quanto para que atores territoriais monitorem as ações e se capacitem na arte do desenvolvimento territorial. Para elaborar o painel de indicadores, recorreu-se à revisão da bibliografia elaborada sobre o tema e resultados parciais de pesquisa em curso no quadro de projetos interinstitucionais implementados no estado de Santa Catarina. O principal resultado deste artigo é uma primeira versão desse painel, o qual servirá de referência para aplicações junto a atores dos territórios estudados, com o duplo propósito de ajustar os indicadores e capacitar os atores sociais no enfoque da CBST.

Despite the onslaught of COVID-19, people still travel and tourism can only thrive further upon its end. Souvenir shopping has long been integral to the tourism business and one’s travel experience. This quantitative non-experimental descriptive correlational study aimed to determine the relationship between souvenir purchase motivations and product attribute preferences among the randomly selected 50 Grade 12 Arts and Design students in the University of San Carlos South Campus for the school year 2021-2022. Two standardized and reliable Likert-type survey tools were used to collect data. Results revealed that students acquire souvenirs for a variety of reasons before making their decision. Students also valued the portability, aesthetic value, and authenticity of an item when looking for a souvenir. Researchers found out that there is a high positive correlation between souvenir purchase motivations and product attribute preferences and the relationship between the two variables is found to be significant, r (48) = 0.547, p < 0.05. This means that students who go on trips have distinct motivations and it affects their decision-making towards purchasing souvenir items. This study recommends that the variables be tested in more settings post-pandemic, as travel restrictions ease worldwide.

Authors: Khorsheed Abbas Akram
Published: August 2022

Today the whole world suffers and fears the epidemic of the Coronavirus and the developed waves in it, as we have now reached the fourth wave, and this is a serious matter. Where the statistics of the Coronavirus in the current data showed that 213 countries are affected by this epidemic, and about 6 millions of deaths are recorded. This virus spreads rapidly, and patients mainly suffer from breathing. The patient who suffers from pre-existing health problems will be more likely to contract this disease, so there was an urgent need for artificial intelligence to enter to quickly detect this virus, so the world turned to deep learning, which is one of the most powerful methods and techniques for classification because of its use of Bayas Rule, where there is no possibility of error. This paper proposes CNN (Convolutional Neural Networks) and PNN (Proprestitc Neural Networks) mixed tomography scanning model to classify Covid-19 images, the proposed network called the CNN-PNN model. The CNN-PNN model can use CNN to compute the dependency and continuity features of the output of the middle layer of the PNN model, and correlate the properties of these middle levels with the final full network to predict the classification.
Human Identification Model Considering Biometrics Features

Published: August 2022

In the medical field, brain classification is an effective technique for identifying a person through his brain print based on the hidden biometrics of high specificity included in the magnetic resonance images(MRI) of the brain, as this privacy strongly contributes to the issue of verification and identification of the person. In this paper, the brain print is extracted from the MRI obtained from 50 healthy people, which were passed through several pre-processing techniques in order to be used in the classification stage through convolutional neural network model, among those pre-classification stages, data collection after extracting the influential features for each image, which was based on linear discrimination analysis (LDA). The experimental results showed the importance of using LDA for feature extraction and adoption as input for K-NN and CNN classifiers. The classifiers proved successful in the classification if the features extracted with the help of LDA were adopted. Where CNN had the ability to classify with an accuracy of 99%, 82% for K-NN. The final stage in identifying a person through a brain fingerprint relied mainly on the model's success in classifying and predicting the remaining data in the testing stage.
An analogy between maxillary anterior teeth dimensions measured using facial proportions and Chu proportion gauge: an in vivostudy
Authors: Sravalli Kodipalli , M. Praveen  , N Kothuri Ravalika
Published: August 2022

Background:A fine balancing of geometric concepts and artistic abilities is required while designing smiles. One of the key elements that makes up the smile frame is tooth size. The maxillary front teeth are the most noticeable in the smile arch, therefore choosing the right tooth size and positioning it in the maxilla improves both aesthetics and treatment outcomes.Aim:This study aimed to compare the dimensions of maxillary anterior teeth measured with vernier callipers and CHU proportion gauge with facial proportions such as intercanthal distance, interalar width and bizygomatic width.Materials and Methods:On a sample of 100, Facial proportions, mesiodistal width, and height of maxillary anterior teeth were recorded using digital callipers and a Chu proportion gauge. The recorded data were subjected to statistical analysis. Mean comparisons of each width were done using a t-test, ANOVA and Tukey’s Post-hoc test considering a p-value less than 0.05 to be statistically significant. Results:Mean values of the combined width of anteriors calculated using Chu gauge was 45.08, and that calculated using Vernier Callipers was 45.85. Multiplying the factor 1.47 to Inner canthal width and 1.42 to Interalar width results in the combined width of the maxillary anterior teeth. A mean difference of 0.02620 ± 0.91777 and 0.4988 ± 0.91777 exists between Inner canthal and Combined Chu’s width with a 0.04% and 0.34% error in younger and elder age populations, respectively. A mean difference of -11.4775 ± 0.91777 and -11.6039 ± 0.91777 exists between Combined mesiodistal width obtained by using Chu’s width and bizygomatic width witha 0.01% error in younger and elder age populations, respectively.Conclusions:This study reported a negligible 0.7 difference in the means of the combined width of anteriors calculated using Chu gauge and Vernier Callipers. Hence, these two methods can be used as alternatives to calculate the width of anterior teeth

3D Hydrodynamics of Pre-supernova Outbursts in Convective Red Supergiant Envelopes
Authors: Tsang Benny T.-H. , Kasen Daniel , Bildsten Lars
Published: August 2022

Eruptive mass loss likely produces the energetic outbursts observed from some massive stars before they become core-collapse supernovae (SNe). The resulting dense circumstellar medium may also cause the subsequent SNe to be observed as Type IIn events. The leading hypothesis of the cause of these outbursts is the response of the envelope of the red supergiant (RSG) progenitor to energy deposition in the months to years prior to collapse. Early theoretical studies of this phenomenon were limited to 1D, leaving the 3D convective RSG structure unaddressed. Using FLASH's hydrodynamic capabilities, we explore the 3D outcomes by constructing convective RSG envelope models and depositing energies less than the envelope binding energies on timescales shorter than the envelope dynamical time deep within them. We confirm the 1D prediction of an outward-moving acoustic pulse steepening into a shock, unbinding the outermost parts of the envelope. However, we find that the initial 2–4 km s−1 convective motions seed the intrinsic convective instability associated with the high-entropy material deep in the envelope, enabling gas from deep within the envelope to escape and increasing the amount of ejected mass compared to an initially “quiescent” envelope. The 3D models reveal a rich density structure, with column densities varying by ≈10× along different lines of sight. Our work highlights that the 3D convective nature of RSG envelopes impacts our ability to reliably predict the outburst dynamics, the amount, and the spatial distribution of the ejected mass associated with deep energy deposition.

Published: August 2022

Identifying the young optically visible population in a star-forming region is essential for fully understanding the star formation event. In this paper, we identify 211 candidate members of the Perseus molecular cloud based on Gaia astrometry. We use LAMOST spectra to confirm that 51 of these candidates are new members, bringing the total census of known members to 856. The newly confirmed members are less extincted than previously known members. Two new stellar aggregates are identified in our updated census. With the updated member list, we obtain a statistically significant distance gradient of 4.84 pc deg−1 from west to east. Distances and extinction corrected color–magnitude diagrams indicate that NGC 1333 is significantly younger than IC 348 and the remaining cloud regions. The disk fraction in NGC 1333 is higher than elsewhere, consistent with its youngest age. The star formation scenario in the Perseus molecular cloud is investigated and the bulk motion of the distributed population is consistent with the cloud being swept away by the Per-Tau Shell.

We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in previous work. We find 914 radial velocity signals with periods longer than 1000 days. Around these signals, 167 cold giants and 68 other types of companions are identified, through combined analyses of radial velocity, astrometry, and imaging data. Without correcting for detection bias, we estimate the minimum occurrence rate of the wide-orbit brown dwarfs to be 1.3%, and find a significant brown-dwarf valley around 40 M
Jup. We also find a power-law distribution in the host binary fraction beyond 3 au, similar to that found for single stars, indicating no preference of multiplicity for brown dwarfs. Our work also reveals nine substellar systems (GJ 234 B, GJ 494 B, HD 13724 b, HD 182488 b, HD 39060 b and c, HD 4113 C, HD 42581 d, HD 7449 B, and HD 984 b) that have previously been directly imaged, and many others that are observable at existing facilities. Depending on their ages, we estimate that an additional 10–57 substellar objects within our sample can be detected with current imaging facilities, extending the imaged cold (or old) giants by an order of magnitude.

We examined the morphology and constructed a highly resolved phylogeny of Q. sontraensis and its relatives (including Q. langbianensis and Q. cambodiensis) using Multiplex ISSR genotyping by sequencing (MIG-seq). The morphological analyses and molecular evidence support the distinction between the new species (Q. sontraensis) and its relatives.
La reprise de poldérisation à Phnom Penh (Cambodge) : un défi social et environnemental
Authors: Pierdet Céline
Published: August 2022

Cet article se propose d’analyser les enjeux d’une accélération de la poldérisation à partir des îles du fleuve Mékong pour soutenir la réalisation de projets immobiliers de grande envergure à Phnom Penh (Cambodge). Cette poldérisation repose sur la méthode ancienne du remblai hydraulique, à l’œuvre depuis 1928 au Cambodge, et qui nécessite de draguer des quantités de sédiments toujours plus importantes pour remblayer les zones basses et encore insalubres de la capitale. Aujourd’hui, les enjeux de ces prélèvements massifs dans le lit même du fleuve sont d’ordre social et environnemental compte tenu des bouleversements qu’ils engendrent, tant pour l’équilibre de cet écosystème dynamique que dans la vie des populations les plus précaires installées le long des berges.
Multiple sclerosis and allergic diseases: is there a relationship?
Authors: Aielli Lisa , Serra Federica , Costantini Erica
Published: August 2022

Immune system disorders characterize various diseases such as multiple sclerosis (MS) and allergic diseases (AD). In MS, T-helper (Th)1 cell phenotype is responsible for the disease onset and long-term evolution. On the other hand, excessive Th2 cell activity has been demonstrated in AD. The simultaneous increase of MS and AD in the same geographical areas, observed in recent years, has questioned the mutually exclusive correlation between MS and AD immunopathogenesis supported by the Th1/Th2 paradigm and has moved the interest in understanding possible overlaps. This manuscript aims to discuss the literature, collected over the past two decades, about the association between MS and AD, and both experimental and epidemiological studies have been reviewed. The results do not provide a solid correlation between AD and MS, although experimental studies support the involvement of the same cells and molecules in the immunopathogenesis of both diseases. Further studies, increasing knowledge on the cellular and molecular mechanisms involved in these two disorders, could help to clarify if a positive or negative association links them and provide the possibility for the development of new therapies.

The world is facing the pandemic situation due to a beta corona virus named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The disease caused by this virus known as Corona Virus Disease 2019 (COVID-19) has affected the entire world. The current diagnosis methods are laboratory based and require specialized testing kits for performing the test. Therefore, to overcome the limitations of testing kits a diagnosis method from chest X-ray images is proposed in this paper. Chest X-ray images can be easily obtained by X-ray machines that are readily available at medical centres. The radiological examinations augmented with chest X-ray images is an effective way of disease diagnosis. The automated analysis of the chest X-ray images requires a highly efficient method for identifying COVID-19 from these images. Thus, a novel deep convolution neural network (CNN) optimized using Grasshopper Optimization Algorithm (GOA) is proposed. The deep learning model comprises depth wise separable convolutions that independently look at cross channel and spatial correlations. The optimization of deep learning models is a complex task due the multiple layers and their non-linearities. In image classification problems optimizers like Adam, SGD etc. get stuck in local minima. Thus, in this paper a metaheuristic optimization algorithm is used to optimize the network. Grasshoper Optimization Algorithm (GOA) is a metaheuristic algorithm that mimics the behaviour of grasshoppers for food search. This algorithm is a fast converging and is capable of exploration and exploitation of large search spaces. Maximum Probability Based Cross Entropy Loss (MPCE) loss function is used as it minimizes the back propogation error of cross entropy and improves the training. The experimental results show that the proposed method gives high classification accuracy. The interpretation of results is augmented with class activation maps. Grad-CAM visualization algorithm is used for class activation maps.
An Open-Ended Web Knowledge Retrieval Framework for the Household Domain With Explanation and Learning Through Argumentation
Authors: Vassiliades Alexandros , Bassiliades Nick , Patkos Theodore , Vrakas Dimitris
Published: August 2022

The authors present a knowledge retrieval framework for the household domain enhanced with external knowledge sources that can argue over the information that it returns and learn new knowledge through an argumentation dialogue. The framework provides access to commonsense knowledge about household environments and performs semantic matching between entities from the web knowledge graph ConceptNet, using semantic knowledge from DBpedia and WordNet, with the ones existing in the knowledge graph. They offer a set of predefined SPARQL templates that directly address the ontology on which their knowledge retrieval framework is built and querying through SPARQL. The framework also features an argumentation component, where the user can argue against the answers of the knowledge retrieval component of the framework under two different scenarios: the missing knowledge scenario, where an entity should be in the answers, and the wrong knowledge scenario, where an entity should not be in the answers. This argumentation dialogue can end up in learning a new piece of knowledge when the user wins the dialogue.

Published: August 2022

Background:

Due to the contradictory results of the effects of Vitamin B6 in reducing the hematotoxic effects of linezolid, the present study aimed to investigate the possible role of Vitamin B6 administration in reducing linezolid-related hematological toxicities in patients with chronic osteomyelitis.

Materials and Methods:

In a randomized double-blind placebo-controlled clinical trial, patients with chronic osteomyelitis were randomly divided into two groups (n = 40 each): the intervention group received Vitamin B640 mg twice daily from the beginning of treatment with linezolid and the control group received placebo with linezolid, both for 21 days. Blood variables including hemoglobin (Hb), white blood cells (WBC), and platelets (PLT) were measured at baseline and at the end of the 1st, 2nd, and 3rd weeks (days 7, 14, and 21) of the intervention.

Results:

There was no significant difference between the groups regarding the count of WBC and PLT and level of Hb at evaluated time points. Furthermore, there was a significant decreasing trend in all parameters within both groups; however, the decreasing trend of both PLT and WBC was slower in the intervention (Vitamin B6) group compared to the placebo group.

Conclusion:

Vitamin B6 has no significant effect in the reduction of hematological adverse effects of linezolid in chronic osteomyelitis patients. However, it could retard the decreasing trend of WBC and PLT counts.
Complicated Ulceroglandular Tularemia

Published: August 2022

A 52-year-old woman presented with a tender swelling in the right axilla, fever, a headache, nausea, and general weakness. On examination, she was found to have lymphangitis on the right arm and red papules on the 1st and 2nd fingers of the right hand. She had had prepared wild rabbit stew 5 days before disease onset. Serology and an ultrasound of the right axilla confirmed the diagnosis of ulceroglandular tularemia. The lymphadenitis did not resolve after streptomycin treatment so an incision was made and 30 cc of purulent fluid drained. Over the course of the next 3 months, the fluid continued to drain. A radiographic fistulography was performed and it revealed a short main channel with a few long channels of varying caliber branching out from it, all terminating in a conglomerate of necrotic axillary lymph nodes. The lesions healed spontaneously and completely over the following 12 months without additional antibiotic therapy. Radiographic fistulography can help plot the course of the fistula/fistulas and demonstrate the anatomic features of the lesion in resource poor settings.

Published: August 2022

Background:

External fixators have been proved to be effective in the treatment of infected nonunion fracture humerus. The current study presents the outcome of treatment of infected nonunion of the humerus by a cyclic compression distraction technique using Ilizarov without radical debridement.

Materials and Methods:

32 patients, 19 males and 13 females. The mean age of the patients was 39.72 years (range, 27–54); patients were presented by infected nonunited fracture humerus after an average of 1.9 surgeries (range, 1–4). All patients were treated by removal of the hardware if present without radical debridement or bone resection to avoid bone shortening and to preserve the blood supply of the bone and soft tissue, Ilizarov application with cyclic compression distraction.

Results:

The mean time of the external fixator application was 179.06 days, and the mean follow-up time was 32.8 months. All patients were united, According to the association for the study and application of the method of the ilizarov scoring system, the functional results were excellent in 8 patients, good in 16, fair in 7, and poor in only 1 patient. The bone results were excellent in 9 patients, good in 16, fair in 5, and poor in 2 patients. The mean post-operative DASH score was 32.43 (range, 10–63), the mean visual analog scale (VAS) score for pain was 3.71 (range: 2–5), while the mean VAS score for satisfaction was 7.41 (range: 6–9).

Conclusion:

Cyclic compression distraction by Ilizarov without radical debridement had shown a satisfactory outcome in the treatment of infected nonunion humerus.

Published: August 2022

Aims:

This study aimed to systematically review the indications, techniques, complications, and insights identified for lower extremity residual amputee limb segment lengthening.

Methods:

Searches in PubMed, Google Scholar, Ovid Medline, Ovid Embase, and the Journal of Limb Lengthening and Reconstruction were performed using terms including “amputee,” “residual limb,” and “stump” combined with “lengthening,” “distraction,” “histogenesis,” “osteogenesis,” and “Callotasis.” Included articles described lengthening amputated tibias or femurs (other segments excluded). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were utilized. Descriptive statistics were performed.

Results:

Twenty-two studies reported lengthening 32 femurs and 31 tibias (63 total segments). Fifteen articles described a single segment, five described two to four (15 total segments), and two described five or more (31 total segments). Lengthening was performed to improve prosthesis fit (21/22 studies, 54/63 segments) or to optimize osseointegration (1/22 studies, 9/63 segments) and utilized an external fixator (52/63) or a motorized intramedullary nail (11/63). Femurs were lengthened an average of 7.7 ± 2.5 cm (60% ± 23%) and tibias 5.8 ± 1.8 cm (97% ± 53%) from a starting length of 12.5 ± 4.6 cm for femurs and 6.7 ± 2.3 cm for tibias. The most common minor problem was pin site infection. The most common major problem was over-lengthening bone beyond the soft tissue envelope, requiring flap coverage, bone excision, or knee disarticulation.

Conclusions:

Amputee lengthening can achieve measurable gains to improve prosthesis use. Over-lengthening can be difficult to manage, if not catastrophic. Osseointegration may be a further rehabilitation solution for amputees struggling with prosthesis problems and willing to consider surgical options.
