The Effectiveness of Chlorhexidine 0.2% Mouthwash vs. Chlorhexidine 0.2% Mouthwash and Toothbrush in Preventing Ventilator Associated Pneumonia a Randomized Controlled Trial
Authors: Karki Nita 
Published: January 2023

Background: Intensive care unit patients are fragile and highly susceptible to infections. Respiratory infections, especially ventilator-associated pneumonia, are the most frequent infectious complications in critically ill patients. Evidence-based patient care treatment practices have been developed by the Center for Disease Control and Prevention to decrease ventilator-associated pneumonia cases. Sixty percent of cases of ventilator-associated pneumonia have been reduced by simple oral routine care.
Aims: To compare the effectiveness of 0.2% chlorhexidine mouthwash solution and chlorhexidine mouth wash with tooth brush and their association in demographic variables in patient admitted in critical care unit.
Methodology: A RCT was conducted from November 2020 to February 2021 in the patient under mechanical ventilation. Ethical clearance and written consent were obtained before collecting information. 30 participants in each control and experimental group were selected by applying the convenient sample technique method. Data was collected using the self-created Performa and the main tool, the Clinical Pulmonary Infection Score, to detect ventilator-associated pneumonia.
Analysis: The data gathered were analyzed and interpreted according to the objective of the study using SPSS version 20. Descriptive statistics were used to find out the demographic result, and the non-parametric Chi-square test was used to compare the data.
Results: Out of 60 participants, majority of patient belongs to 51-60 years, i.e. 11 (36.67%) in control group and 61-70 years, i.e. 13 (43.33%) experimental group. Patients who received chlorhexidine with tooth brushing intervention had higher Clinical pulmonary Infection Score values and higher rate of Ventilator Associated Pneumonia occurrence in experimental group 3(10%) than in control group 1(3.33%).
Conclusion: Combining tooth brushing with 0.2% chlorhexidine did not provide additional benefits over 0.2% chlorhexidine alone. There is no significant reduction in the rate of ventilator-associated pneumonia by applying 0.2% chlorhexidine with toothbrushing.

Background: The purpose of this research was to compare the effect of duration of cement dust on the liver organ of albino rats. In this study, a glass house animal exposure chamber was fabricated using a plexi-glass and two blowing fans of adjustable revolution.
Methodology: A total of twenty five rats averagely weighing 135g were used and categorized into five groups composed of 5 rats each: A group (without cement exposure); B group (exposed to 200g of cement dust for 1 hour daily for 15days); C group (exposed to 200g of cement dust for 1 hour daily for 30 days); D group (exposed to 200g of cement dust for 1 hour daily for 45 days) and E group (exposed to 200g of cement dust for 1 hour daily for 60 days). The means of exposure was by inhalation. After the exposure periods, the animals were sacrificed, blood collected in plain bottle and analyzed for some liver function.
Results: The ANOVA result showed that there were significant changes (p < 0.05) in the levels of some liver function markers such as alkaline phosphatase (ALP), Total protein (TP), Albumin and Conjugated bilirubin (CB), and the alteration patterns were irregular. On the other hand, there were no changes (p>0.05) in the levels of Aspartate amino transferase (AST), Alanine amino transferase (ALT) and Total bilirubin (TB) among the groups.
Conclusion: This study has therefore shown that exposure to cement may cause some decrease of liver injury in rats regardless of the duration of the exposure.

Published: January 2023

The SOMAÏR open-pit uranium mine, commonly known as « Société des Mines de l’Aïr Aïr » (Arlit, Northern Niger), has been using the topographic method for several years to monitor and estimate mine production. However, the method has limitations and constraints in the implementation and reliability of the results. The company is considering the use of an innovative, more reliable and economical method. Thus, a pilot project using drones is being implemented. The objective of this work is to carry out a comparative study between the topographic method and the photogrammetric method for monitoring and acquiring data from mining operations. Thus, the data acquired by topometry using a total station, for the so-called classical method and by drone for the photogrammetric method, were analyzed and interpreted. These two (2) methods were used for the follow-up of the M4_Art North ore deposit and the G4_Taossa pit of the SOMAÏR mine. The results of the analysis and processing show that the data acquisition time by drone is relatively low (30 to 40 minutes) compared to that of the topographic surveys (21 to 60 minutes). However, data processing times for the photogrammetric method are relatively higher (50 to 60 minutes) than those for the conventional method (14 to 20 minutes). Nevertheless, this processing time of drone images can be improved with powerful computer equipment. In addition, the use of UAVs offers additional advantages in the monitoring of mining operations, particularly with regard to worker safety, precision in the calculation of dimensions, volumes and tonnages at the mining slice and at the overburden. Immediate analysis of the two methods shows the accuracy of the drone for the front survey and also shows all the details present on the ground, namely: the machines used, the purging products and other products or elements used. So, it would be wise to opt for the drone in downhole activities.

Published: January 2023

Aims: Dracunculiasis is a neglected disease caused by a parasitic nematode, Dracunculus medinensis, also called the filaria of Medina. An outbreak of this disease occurred in the Salamat province in Chad in 2019, while the eradication of this disease worldwide was in its final stage. The outbreak occurred in the Bogam village (Liwi area), where this disease has never been reported in the past. The present work is aimed at identifying the factors that would have favored that outbreak, and the constraints that delay the eradication of dracunculiasis in Chad.
Study Design: Retrospective study.
Place and Duration of Study: The data retrospectively analyzed are those recorded during the census of patients by the Chadian National Guinea Worm Eradication Program (PEVG), from 2019 to 2020, and supplemented by those contained in the registers of previous years. The analyzes were carried out in N'Djamena, between July and November 2021, within the Laboratory of the Faculty of Medicine.
Methodology: The census of patients was carried out during a survey from 2019 to 2020 by PEVG. These data have been supplemented by those contained in the registers of previous years. Data were first stored in a Microsoft (Excel 2007 Software) spreadsheet, then transferred to the SPSS version 20.0 Software, after removal of outliers and input errors. The Chi-Square test (χ2) made it possible to compare the percentages at the threshold of p<0.005.
Results: In summary it appeared that 52.4% of the patients were 5 to 20 years old, 62% were female, 90.48% lived in Bogam, 95.2% used dirty water from ponds and traditional wells, 33% were farmers, and 33% were breeders. In addition, most of the patients became infected between March and November 2018. The following risk factors combined could explain the Bogam 2019 dracunculiasis outbreak namely: cohabitation with infested pets coming into contact with water, the behavior of young and active people with respect to water, consumption of unhygienic water, gender, lack of containment of some patients that could enter water barefoot, period extending from April to September.
Conclusion: This work highlighted the obvious role of pets as a reservoir on the one hand, and the effectiveness of the PEVG in the fight against dracunculiasis through a treatment protocol combining a wet bandage associated with oral diclofenac + amoxicillin + paracetamol.

Published: January 2023

Background: Pectoralis-Serratus interfascial plane block is a peripheral block of the thoracic wall that presents analgesia of its anterolateral portion. Dexmedetomidine, a specific α-2 adrenoceptor agonist, has sedative, anxiolytic, and analgesic properties. The aim of this work was to assess the analgesic safety and efficacy of Pectoralis-Serratus interfascial plane block in contrast with dexmedetomidine infusion for unilateral radical mastectomy.
Methods: This prospective randomized study was carried out on 60 adult patients with American Society of Anaesthesiologists (ASA) physical status I/II scheduled for elective unilateral radical mastectomy. The cases were classified randomly into two equal groups: group I: received ultrasound guided pectoralis serratus interfacial plane block and group II: received dexmedetomidine infusion. All patients were subjected to routine laboratory investigations (coagulation profile, CBC, liver and renal function tests) and visual analogue scale (VAS).
Results: Total amount of fentanyl increments, Ramsey sedation score and total analgesic (morphine) consumption in the 1st 24 hours postoperative were significantly decreased in group I contrasted to group II (P<0.001). Time of the first rescue analgesia was significantly increased in group I than group II (P <0.001). Bradycardia was considerably decreased in group I than group II (P = 0.026). VAS at rest and at exercise were significantly decreased at 1, 2, 4 and 6 hours in group I than group II (P<0.05).
Conclusions: PECS-II blocks are superior to dexmedetomidine infusion provide adequate post-operative analgesia (lower VAS and total analgesic consumption with increased 1st rescue analgesia) with hemodynamic stability. and less complications.

Published: January 2023

AbstractIn a retrospective case series of 10 children with cryptogenic FIRES, we sought to describe the early clinical course and potential biomarkers following anakinra initiation. Six children achieved anesthetic withdrawal within 3 weeks of therapy and one in week four. Of the available cEEG (six children), CRP (10 children), and serum cytokine (six children) studies, there were temporal changes in highly epileptiform bursts (observed in three children), CRP, IL‐6, and IL‐10 levels that might parallel clinical progression. These observations may represent candidate biomarkers for monitoring clinical progression and therapeutic interventions including anakinra, which merits further investigation in future studies.
Nuclear Imaging of CAR T Immunotherapy to Solid Tumors: In Terms of Biodistribution, Viability, and Cytotoxic Effect
Authors: Ren Mingliang , Yao Bolin , Han Bing , Li Cong 
Published: January 2023

AbstractImmunotherapy has become a mainstay of cancer therapy. Since chimeric antigen receptor (CAR) T immunotherapy achieves unprecedented success in curing hematological malignancies, the possibility of it revolutionizing the paradigm of solid tumors has aroused increasing attention. However, the restricted accessibility to tumor parenchyma, the immunosuppressive tumor microenvironment, and antigen heterogeneity of solid tumors make it difficult to replicate its success. Therefore, dynamic evaluation of CAR T cells’ tumor accessibility, intratumoral viability, and anti‐tumor cytotoxicity is necessary to facilitate its translation to solid tumors. Besides, real‐timely imaging above events in vivo can help evaluate therapeutic responses and optimize CAR T immunotherapy for solid tumors. Nuclear imaging, including positron emission tomography (PET) and single‐photon emission computed tomography (SPECT) imaging, is frequently applied for evaluating adoptive cell therapies owing to its excellent sensitivity, high tissue penetration, and great translation potential. In addition, quantitative analysis can be performed in dynamic and noninvasive patterns. This review focuses on recent advances in PET/SPECT technologies and imaging probes in monitoring CAR T cells’ migration, viability, and cytotoxicity to solid tumors post‐administration. Prospects of what should be done in the next stage to promote CAR T therapy's application in solid tumors are also discussed.

AbstractA method is presented to manipulate the final morphology of roll‐to‐roll slot‐die coated poly(3‐hexylthiophene) (P3HT) by optically exciting the p‐type polymer in solution while coating. These results provide a comprehensive picture of the entire knowledge chain, from demonstrating how to apply the authors’ method to a fundamental understanding of the changes in morphology and physical properties induced by exciting P3HT while coating. By combining results from density functional theory and molecular dynamics simulations with a variety of X‐ray experiments, absorption spectroscopy, and THz spectroscopy, the relationship between morphology and physical properties of the thin film is demonstrated. Specifically, in P3HT films excited with light during deposition, changes in crystallinity and texture with more face‐on orientation and increased out‐of‐plane charge mobility are observed.

AbstractDeveloping electrocatalysts with high catalytic performance and selectivity is crucial for electrochemical CO2 reduction reaction (CRR). There are many catalyst studies of transition metal (TM) atom doping to sp2 carbon material, such as graphene or carbon nanotubes. On the other hand, graphdiyne (GDY) has both sp and sp2 hybridization and stable pores, so we can tune its interaction with TM. Following the successful experimental synthesis of Ni atom doping to GDY monolayer, the CRR activity of double–atom catalysts was evaluated, including homo and hetero metal‐Ni doped on the GDY monolayer (MNi@GDY where M is Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) using the density functional theory calculations. The valence‐electron number of the catalytic center shows a strong positive correlation to the limiting potentials in the volcano plot. NiNi@GDY is the most promising candidate for converting CO2 to produce CH4 with a remarkable low limiting potential of −0.28 V, which is better than Ni@GDY and Ni3@GDY counterparts. NiNi@GDY shows excellent thermal stability and ability to suppress the competing hydrogen evolution reaction, showing its high selectivity to CH4.

Published: January 2023

AbstractGradient index (GRIN) lenses embody a powerful technology that enables control of electromagnetic wave propagation over wide frequency bands. However, GRIN lenses that achieve multifunctional (i.e., dual broadband) performance have not been realized mainly due to the limitations of conventional techniques such as Transformation Optics (TO). This paper proposes a multi‐objective inverse‐design approach for the optimization of multi‐band GRIN lenses with highly constrained aperture sizes. A candidate lens design is fabricated from a ceramic material using a new additive manufacturing approach allowing for spatially‐varying permittivities between 2–6.5 to be achieved at sub‐cm resolution. Measured results validate the candidate functionalized ceramic GRIN lens's simulated multi‐band performance and demonstrate the efficacy of the proposed inverse‐design procedure.

Published: January 2023

AbstractWearable electronic technology is developing rapidly and has been widely used in human‐computer interaction, smart homes, telemedicine, rehabilitation training, sports monitoring, object tracking, etc. Fibers, as the basic elements of clothing, have become important carriers of wearable electronics. The fiber‐shaped triboelectric nanogenerator (F‐TENG) is typically a 1D structure that is highly flexible and can be woven from 1D to 2D or even 3D textiles. F‐TENG has both the structural characteristics of fibers and the function of energy conversion of the triboelectric nanogenerator (TENG). Therefore, it can be worn on the body both as an energy converter to convert the mechanical energy of human movement into electrical energy and as a self‐powered sensor to convert human movement information into electrical signals. Herein, this review comprehensively introduces the recent progress of F‐TENG, including the scale preparation method of fibers, the weaving method of fibers, triboelectric‐based multifunctional fiber, and various fibers for energy harvesting and self‐powered sensing. Finally, the challenges and opportunities in the field of F‐TENG are discussed.
