In countries where tuberculosis (TB) is endemic, coinfection of COVID-19 and TB is often encountered, which increases the risk of developing severe forms of COVID-19. Objectives: The aim of this study was to determine the prevalence of COVID-19/TB coinfection at the Epidemic treatment center (ETC) in Saint-Louis (Senegal) and to describe the epidemiological, clinical, paraclinical, and outcome profile of co-infected patients. Patients and Methods: This is a retrospective, cross-sectional, descriptive cohort study based on the records of COVID-19/ TB co-infected patients who were hospitalized at the ETC in Saint-Louis (Senegal) over an 18-month period from March 2020 to September 2021. Results: Out of a total of 454 hospitalizations, we collected records of 9 patients co-infected with COVID-19/TB, resulting in a prevalence of 2%. The study included patients with a median age of 34 years (range: 10-86 years), with a male predominance (7 cases) and a sex ratio of 3.5. The majority of patients (88.9%) had severe forms of COVID-19. Dyspnea and cough were reported in all patients (100%). Pulmonary TB was the most frequent localization, with 9 cases. The diagnosis of COVID-19 was confirmed by nasopharyngeal PCR in all patients (100%). Bacilloscopy was positive in 3 out of 5 cases. One patient tested positive for GeneXpert<sup>?</sup> MTB/RIF without rifampicin resistance. All patients were prescribed the hydroxychloroquine-azithromycin combination and anti-tuberculosis treatment. Out of the nine patients, four recovered (44.4%) and five died (55.5%). Conclusion: COVID-19/TB coinfection had a low prevalence in our cohort, but was associated with a high mortality due to the frequent occurrence of severe forms of the disease.展开更多

Several risk factors are involved in the occurrence of respiratory distress that can lead to death despite resuscitation measures. Objectives: The aim of this study was to describe the epidemiological, clinical, paraclinical, therapeutic, and evolution profile of patients infected with SARS-CoV-2 hospitalized at the CTE of Saint-Louis (Senegal) during the first two waves. Patients and Methods: We conducted a retrospective, cross-sectional, descriptive, and analytical study that included all patients hospitalized at the ETC of Saint-Louis (Senegal) with SARS-CoV-2 infection from March 2020 to April 2021. Results: A total of 358 cases were collected, 256 (71.5%) during the first wave and 102 (28.5%) during the second wave. The mean age was 49.5 years (19.5). There was a male predominance (58.4%), with a sex ratio of 1.4. Hypertension was the main comorbidity, with 87 cases (24.3%). The most common functional signs were cough in 194 cases (54.2%), dyspnea in 143 cases (40%) and ageusia in 134 cases (37.4%). Thoracic CT scans were performed on 20 patients (5.6%), with severe involvement (50% - 75%) observed in 50% of cases. Hydroxychloroquine-azithromycin was prescribed to 351 patients (98%). Overall, 338 (94.4%) recovered and 17 (4.7%) died. In multivariate analysis, factors associated with death were male sex [OR = 2.645;95% CI: 1.530 - 4.785;p = 0.011], age 60 years [OR = 1.039;95% CI: 0.564 - 1.914;p = 0.002], the presence of comorbidities [OR = 2.171;95% CI: 0.564 - 3.429;p = 0.033], SpO2 (ambient air) 95% [OR = 2.061;95% CI: 0.616 - 3.827;p = 0.03], acute respiratory distress syndrome (ARDS) [OR = 0.635;95% CI: 0.316 - 1.275;p = 0.001], severe form [OR = 1.664;95% CI: 0.298 - 2.478;p = 0.016], occurrence of complications [OR = 0.521;95% CI: 0.287 - 0.944;p = 0.032], high creatinine levels [OR = 2.061;95% CI: 1.616 - 3.827;p = 0.026], and lymphopenia [OR = 0.485;95% CI: 0.370 - 0.636;p = 0.001]. Conclusion: In our series, infection with SARS-CoV-2 was associated with low lethality. Several risk factors were identified that need to be considered for successful management of patients.展开更多

The research shows that some valuable spatial correlation patterns can be further found from the clustering result comparison with multi-themes, based on traditional spatial clustering as the first step. Those patterns can tell us what relations those themes have, and thus will help us have a deeper understanding of the studied spatial entities. An example is also given to demonstrate the principle and process of the method.展开更多

Nevertheless, they mainly have weaknesses in extracting most important terms when input text has not been rectified grammatically, or even has non-alphabetic methodical and math or chemical notations, and cross-domain inference of terms and phrases. In this paper, we propose a novel Text-Categorization and Term-Extraction method based on human-expert choice of classified categories. Papers are the training phase substances of the proposed algorithm. They have been already labeled with some scientific pre-defined field specific categories, by a human expert, especially one with high experiences and researches and surveys in the field. Our approach thereafter extracts (concept) terms of the labeled papers of each category and assigns all to the category. Categorization of test papers is then applied based on their extracted terms and further comparing with each category’s terms. Besides, our approach will produce semantic enabled outputs that are useful for many goals such as knowledge bases and data sets complement of the Linked Data cloud and for semantic querying of them by some languages such as SparQL. Besides, further finding classified papers’ gained topic or class will be easy by using URIs contained in the ontological outputs. The experimental results, comparing LPTC with five well-known term extraction algorithms by measuring precision and recall, show that categorization effectiveness can be achieved using our approach. In other words, the method LPTC is significantly superior to CValue, TfIdf, TermEx, GlossEx and Weirdness in the target study. As well, we conclude that higher number of papers for training, even higher precision we have.展开更多

In countries where tuberculosis (TB) is endemic, coinfection of COVID-19 and TB is often encountered, which increases the risk of developing severe forms of COVID-19.
