Published: August 2021

The aim of this work was to evaluate the effect of Thymus vulgaris L phenolic extracts (TVPE) on the growth of Streptococcus thermophilus and Lactobacil- lus delbrueckii subsp. bulgaricus, and the impact of their addition in small amounts (2-8%) to a set-style yogurt with regard to variations in physico- chemical, bacteria count and organoleptic properties during 21 days storage at 4°C. The phenolic components were extracted from the crushed aerial parts of the test plant by cold maceration in hydromethanolic solution (methanol: water, 80:20 v/v). The plant polyphenolic profile was determined by HPLC. The survival ability of yogurt starter cultures in the presence of TVPE was evaluated through the determination of minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The total phenolic content (TPC) was 20.2 ± 0.57 μg GAE / mg extract. The amount of flavonoid compounds was 39.83 μg EQ/mg extract. As the quantitative measurements revealed, apigenin and fisetin (8.17, 6.83, μg GAE /mg extract respectively) emerged as major phenolic compounds from thyme aerial parts. The MIC and MBC against the growth of both lactic bacteria were obtained at 60% of TVPE concentration. A significant (p< 0.01) changes in pH, trable acidity and apparent viscosity were observed in all experimental yogurts. The best scores of sensory evaluation were recorded in samples added with 2% and 4% of TVPE as well as the control. Based on collected data, 2% and 4% of TVPE can be incorporated into yogurt without risk of deterioration in physicochemical quality or inhibition of lactic bacteria.

Maize plays a socio-economic role in Senegal. However, it is considerably damaged by Sitophilus Zeamais, a beetle of the Curculionidae. Areas likely to favor the survival or extinction of Sitophilus zeamais can be identified because genetic diversity influences the adaptability of the individual. Our study aims to highlight a possible variation and structuring of Sitophilus zeamais according to five agroecological zones (AEZ) in Senegal, namely Nord Bassin Arachidier (NBA), Sud Bassin Arachidier (SBA), Sénégal Oriental Haute Casamance (SOHC), Basse Moyenne Casamance (BMC) and Zone Sylvo-Pastorale (ZSP). The purpose of this study is to reduce crop losses by recommending to farmers peas where the insect is reluctant to survive. So far, genetic studies on this insect have traced its phylogeny and its geographical distribution in Africa in general. Senegal has never been specifically studied. To achieve this goal, 89 individuals were captured in the 5 zones. The exploitation of the cytochrome B gene corresponding to these individuals revealed a high genetic diversity in the NBA, SBA, and SOHC and low in BMC and ZSP, but also a genetic structuring of the insect according to agroecological zones. Thus, the agroecological zones of the NBA, the SBA and the SOHC are favorable to its survival, while those of the BMC and the ZSP limit its expansion.

Published: August 2021

The present study on olive tuberculosis commenced by isolating bacteria of the genus Pseudomonas from the soils and necrosis of collected olive trees. A total of 180 samples were used in this study: (100) rhizospheric soil samples: (60) samples at the region of Ain Témouchent and (40) at the region of Sig in western of Algeria. In total, (80) galls were collected (40) at branch level and (40) galls at olive tree leaf (level). The isolates were identified by microbiological (macroscopic and microscopic examination), physiological (growth in the presence of Salt (NaCl), growth at different pH values and growth at different temperatures) and biochemical methods (the LOPAT and Galeries Api 20 NE test to identify species of the Pseudomonas group and conventional biochemical tests to identify the subspecies P. syringae pv. Savastanoi).This allowed to identify 110 isolates of Pseudomonas (60 isolates of P. aeruginosa, 35 isolates of P. fluorescens and 15 isolates of P. syringae pv Savastanoi the causal agent of olive node disease) which are now part of the collection of Pseudomonas bacteria of the laboratory of the Biotechnology Department (USTO-MB). The selection of technological performance isolates useful for our agriculture could solve phytopathological problems and finally constitute a collection of the bacteria preserved.

In previous work, 70 Bacillus sp. isolates originating from 4 soil plots from southwestern Algeria were studied for their poten al plant growth promoting (PGP). In this study, pH, organic ma er, texture, Calcium carbonate, and Electrical conduc vity of the soil samples were determined, 08 selected isolates were idenfied based on rRNA 16S and FAME analysis using GC. Antimicrobial activity against bacteria and fungi were also investigated. All the four soils were moderately Calcium carbonate, pH of soil was alkaline. Our results showed that the electrical conductivity was high for all soils and the four soil isolates in semi-arid and arid regions were poor in organic matter. In addition, Fatty acid analysis showed the presence of 17 di erent fa y acids. Three fa y acids, 15:0 iso, 16:0, and 17:0, 17:0 were present in all isolates. Thus, the isolates were classified into two clusters which were con rmed the results of 16SrRNA sequence analysis. Preliminary screening revealed that the Bacillus thuringiensis isolates showed strong an bacterial and an fungal proper es against S. aureus (between 7mm to 11mm) and A. niger (between 7mm to 8mm). The aim of the present study is the screening of eight Bacillus cereus strains isolated from four rhizosphere soil sample of South-Western region of Algeria province for their an microbial activity.

Endophytic bacteria are found inside host plants without causing disease symptoms, and form a range of di erent bene cial rela onships. In this study, four bacterial strains were isolated from roots, cladodes and non gus- tatory fruits of Opun a cus-indicaL. collected from the Algerian semi-arid region. The bacteria were able to grow at temperatures as 45 °C. 16SrRNA sequencing revealed the iden ty of isolates as Pseudomonas pu da(E1)with 98% similarity,P. brassicacearum(E2) and Klebsiella pneumonia (E3,E4)with 99% similarity. The strains were tested in vitro for their biocontrol ac vity against phytopathogenic fungus, and found to have the ability to inhibit the Fusarium oxysporum f. sp. albedinis and Aspergillus niger growth. We noticed that the most important inhibitory effect recorded with P. pu da (69.78±3.93 and 65.15±2.8), and that the feeble antagonistic effect recorded with P. brassicacearum (20.57±6.04 and 8.52 ±2.8) against of F.oxysporum f.sp albdeinis and A.niger. The plant growth promo ng (PGP) proper es were demonstrated through wheat (Triticum aestivum L.) based bioassay under hydroponic condi ons.The inocula on of bacteria showed an increase in density, length of roots and stems, indica ng the PGP abili es of these bacteria. P. pu da showed a poten al for growth of wheat plant.We no ced respectively the length of both stems and roots (17.34 ± 0.54 mm; 11.07 ± 0.67 mm), and we found that fresh and dry weight was (0.23 ± 0.029 g; 0.0375 ±0.003 g). Overall the results showed that isolates characterized were able to improve the growth of plants, and inhibit the propaga on of phytopathogenic fungi. To our knowledge, this is the rst report describing the isola on of bacteria from O. cus-indica(L.) in Algerian semi-arid region.

The different presentations, comorbidities, and outcomes of COVID-19 highlight the importance of early identification and proper triage of patients. High-risk patients can be divided into patients with common comorbidities and patients with special categories. Common comorbidities include, but are not limited to, Cardiovascular Disease (CVD), Diabetes Mellitus (DM), immunosuppression, underlying respiratory disease, and obesity. Certain categories of COVID-19 patients are also at increased risk, including neonates and pregnant women. In the present article, we delineate the reported risk factors for acquisition of infection, and for increased severity of the clinical disease. We also comparatively analyze those risk factors associated with COVID-19 and with the antecedent human acute respiratory syndrome-causing viruses, SARS-CoV-1 and MERS-CoV. We hypothesize that the structural similarities of the three viruses predict a similarity in the profile of high-risk patients. Several pathophysiological patterns have been detected to support this theory.
Au carrefour des internationalismes
Authors: Di Donato Michele 
Published: August 2021

À partir d’une étude de cas centrée sur le Parti socialiste français, cet article a pour but de contribuer aux débats sur l’histoire des internationalismes. En analysant l’expérience des rencontres des partis socialistes d’Europe du Sud convoquées par le PS de François Mitterrand en 1975 et 1976, il met en lumière les chevauchements et les entrelacements entre les différentes sphères et échelles de la coopération internationale : l’internationalisme des socialistes, la diplomatie des États, la coopération européenne et transatlantique. Il vise à démontrer que cet épisode représente un moment important dans un processus d’« apprentissage de l’international ». À sa suite, le PS est amené à mettre en question son approche fondée sur la primauté de la politique intérieure et à se poser de façon plus concrète le problème des compatibilités internationales de sa politique.

Published: August 2021

Abstract
Placenta accreta in cesarean section presents problem for an anesthesiologist. It may cause massive bleeding which is usually managed with massive transfusion. In this case series, we report cases of placenta accreta patients undergoing cesarean section managed with massive transfusion. A retrospective case series review of patients diagnosed with placenta accreta undergoing cesarean section with massive bleeding and massive transfusion was conducted between April 2018 and March 2019 in Dr. Moewardi General Hospital using the medical record data. A total of five patients with placenta accreta underwent cesarean section, and massive bleeding as well as massive transfusion was identified. Hysterectomy was performed at the time of cesarean section in all cases. All patients underwent general anesthesia, had central venous catheter, and required massive transfusion. Patients were transferred to the intensive care unit postoperatively. There were no transfusion reactions and maternal death.
Herpes Zoster Co-Infection with COVID-19
Authors: Altaf Irfan 
Published: August 2021

Abstract
Clinical presentation of COVID-19 infection can be variable in the current pandemic even in patients presenting to the clinic with a mild history of upper respiratory complaints. Various cutaneous manifestations have been noticed in COVID-19 patients with herpes zoster (HZ) being one among them. HZ is an infection that results when varicella zoster virus reactivates from its latent state in the posterior dorsal root ganglion. Here, we aim to expand our knowledge by reporting three cases of associated zoster infection in COVID-19 patients admitted to our intensive care unit in view of respiratory complaints. All the three patients admitted, had revealed lymphocytopenia at the time of HZ diagnosis, and were managed conservatively throughout the course. In all the cases, acyclovir/valacyclovir led to the resolution of lesions in 10 days. No postherpetic sequelae were observed. We here suggest that the clinical presentation of HZ at the time of the current pandemic should be considered as an alarming sign for a latent subclinical SARS CoV-2 infection and thorough follow-up of such patients be adopted.

Abstract

Background:
The addition of adjuvants to local anesthetics in the peribulbar block might be a method to elevate block quality. This study aimed to determine the effectiveness of peribulbar local anesthesia adjuvants using dexmedetomidine 20 mcg and dexamethasone 5 mg.

Patients and Methods:
This study was a single-blind randomized clinical trial. Patients were divided into three groups who received peribulbar group: Group C (4 ml of levobupivacaine 0.5% and 4 ml of 2% lidocaine added with 1 ml of normal saline), Group D (4 ml of levobupivacaine 0.5% and 4 ml of 2% lidocaine added with 1 ml of dexamethasone 5 mg), and Group M (received 4 ml of levobupivacaine 0.5% and 4 ml of 2% lidocaine added with 1 ml of dexmedetomidine 20 mcg). Sensory and motor block onsets and durations were assessed.

Results:
There were 42 patients included. The sensory block onset was 70.7 s in Group M and the slowest in Group C (152.1 s). The longest sensory block duration was found in Group D (259.3 min) and the shortest in Group C (143.2 min).

Conclusion:
Dexamethasone 5 mg adjuvant affected sensory block onset, sensory, and motor block duration but did not affect motor block onset, while dexmedetomidine 20 mcg adjuvant affected sensory and motor block onsets as well as sensory and motor block durations.

Abstract

Background:
A scoring system to predict patient's prognosis may aid clinicians in deciding patient's treatment continuation. This study aimed to investigate the reliability of Acute Physiology and Chronic Health Evaluation (APACHE) II score in predicting mortality in critically ill COVID-19 patients in intensive care unit (ICU).

Patients and Methods:
This retrospective observational study included the data from medical records of critically ill patients from April to November 2020. The collected data were patient's identity, age, gender, comorbid, Glasgow coma scale (GCS) score, temperature, mean arterial pressure, heart rate, hematocrit, leukocyte, natrium, kalium, serum creatinine, blood pH, PaO2 level, and history of organ insufficiency or immunocompromised within 24 h after ICU admission. Patient's outcome (survival and nonsurvival) was recorded.

Results:
A total of 120 patients were included in the study. APACHE II score was significantly higher in nonsurvival compared to survival group (19.12 vs. 12.33; P < 0.001). The area under curve value was 0.955 (P < 0.001) which indicated APACHE II score as a good predictive value for mortality. The cutoff value of the APACHE II score for mortality prediction in this study was 15, with sensitivity, specificity, positive prediction value, negative prediction value, and accuracy of 94%, 79.4%, 80.6%, 94.3%, and 86.7%, respectively. GCS score, heart rate, age, and serum kalium level were related to mortality.

Conclusion:
The APACHE II score is reliable in predicting mortality in critically ill COVID-19 patients in ICU.

Authors: Dissi Mahdi Gambo , Ibrahim Salisu Ahmed , Tanko Yusuf , Mohammed Aliyu 
Published: August 2021

Background:
Adverse health outcomes of night shiftwork (NSW) have been reported from observational studies but interventional researches mimicking NSW are dearth. This study aimed to simulate NSW and investigate its effect on lipid profile, hematological, and immunoinflammatory parameters in adult male Wistar rats.

Materials and Methods:
Sixteen male Wistar rats aged between 8 and 10 weeks, weighing 100 g ± 12 g were equally and randomly divided into control and NSW groups. Night shift-work group was sleep restricted and exposed to light at night for 6 weeks. Lipids were analyzed using their respective Randox kits and chemistry Autoanalyser (mindry Ba-88a). Full blood count was done using an Automated Hematology analyzer (Mindray BC-10) and CD 4+ T-cells were estimated using an automated Partec Cyflow counter. Data were analyzed using SPSS V20.0 and summarized using mean ± standard error of means. Student's t-test was used to investigate differences between the groups and P ≤ 0.05 was considered as statistically significant.

Results:
The results demonstrated NSW rats to exhibit trends toward lower high-density lipoprotein, higher triglycerides, low-density lipoprotein, and lipid ratios compared to controls (P > 0.05). In addition, NSW group exhibited significant reduction in total WBC count, marginal decrease in CD4+ T-cells, and absolute lymphopenia. In addition, while erythrothrombotic parameters of the two groups appeared statistically similar, platelets-to-lymphocytes ratio is slightly higher and red cell distribution width coefficient is significantly lower in the NSW group.

Conclusion:
The present study has demonstrated the potentials of night shiftwork to increase atherogenic lipids, lower cardioprotective lipids, impair immunological competence and increase systemic inflammation in male Wistar rats. These finding have highlighted the need for extensive research effort in order to fully understand mechanisms through which NSW affect immunoinflammation, metabolic and cardiovascular health.
