Trend of HIV/AIDS Reported Cases in Morocco Between 1986 and 2019: A Time Series Analysis

Background: Morocco is a low endemic country of HIV/AIDS that achieved the goal of the second and third 90-90-90 targets in 2019 while still 78% of people living with HIV know their HIV status. The aim of this study was to analyze time trends of HIV/AIDS reported cases during the last 33 years taking into consideration the implementation of voluntary HIV counseling and testing (HCT) services in primary health care facilities. Methodology: This was a time series of HIV/AIDS reported cases at national level between 1986 and 2019. Variable collected for each year were HIV/AIDS reported per 100000 H, age category, gender, origin, CD4 count and route of transmission. Trend of HIV/AIDS reported cases was assessed by Joinpoint Regression Analysis. Annual percentage changes (APCs) were estimated to identify the years (joinpoint) when significant changes occurred in the trend. We therefore examined trends in HIV/AIDS reported cases according to epidemiological variables. Results: Cumulative HIV/AIDS reported cases during the study period was of 17 000. Joinpoint regression showed an increase in HIV/AIDS reported cases between 1986 and 2019. The APC for the period 1986-2012 was of 13.4 (95% CI: 12.0 to 14.8, p <0.05) and the APC from 2012 to 019 was of 5.4 (95% CI: 2.5 to 8.5, p<0.05) with a significant break in the same joinpoint year than HCT implementation in primary health care settings. In stratified analysis, HIV/AIDS reported cases increased but not significantly after joinpoint. A significant decrease was noted in 2015 in urban areas (APC = -10.0, 95% CI: -17.0 to -2.3, p<0.05). Conclusions: HIV/AIDS reported cases were increasing over 33 years, with a significant rise after 2012by 5% per year, corresponding to HCT integration into primary health care setting. Furthermore, Morocco is may be on the right way to eliminate HIV/AIDS in urban areas.

Isolation of Microorganisms Associated with Palm Oil Contaminated Soil

Aim: Palm oil processing generally generates lots of wastewater (palm oil mill effluent), this is usually discharged into the environment in the untreated form and subsequently causes several environmental issues. There is therefore need to isolate microorganisms that can be used to clean up the palm oil contaminated environment especially the soil. Methods and Results: Palm oil contaminated soil was obtained from Oba Adeyemi palm oil mill in Oyo, Oyo State, Nigeria, other soil samples which were purposely contaminated with palm oil, were obtained from Ajayi Crowther University Oyo, Oyo State. Isolation, characterization and identification of microorganisms were carried out using morphological and biochemical characterization. The isolates were preliminarily screened for lipolytic activities, this was confirmed by growth on the mineral salt medium after 7 days, signifying hydrolysis. One of the prominent isolates was further identified by sequences analysis of 16S rRNA genes. Forty-one bacterial isolates were identified, which included species of Bacillus (80 %), Pseudomonas (20 %) in the oil mill contaminated soil sample and Bacillus spp. (100 %) in the purposely contaminated soils. Twenty-nine fungal isolates including species of Aspergillus, Oidiodendron, Geotrichum, Penicillum, Saccharomyces were isolated with Aspergillus fumigatus having the highest frequency of occurrence (37.5 %) in artificially contaminated soil and Saccharomyces spp. having the highest frequency of occurrence (91 %) in palm oil contaminated soil from the palm oil mill. Sequencing of the 16S rRNA of one of the prominent isolates showed that it was identified as MN607220 Saccharomyces cerevisae. All the bacterial and fungal isolates had lipolytic activities except Bacillus mycoides and Oidiodendron sp. respectively. Nine of the ten Saccharomyces sp. had lipolytic activities. Conclusion: These screened organisms could therefore be employed for the cleanup of palm oil contamination in the environment. Significance and Impact of Study: Thereby ridding the environment of possible toxic effects especially in areas of need like Malaysia

Case Report: De novo Ocular Myasthenia Gravis after the mRNA Vaccine for SARS-COV2

Autoimmune Myasthenia gravis is a neuromuscular junction disease caused by destruction of the acetylcholine receptor on the postsynaptic membrane, mediated by autoantibodies and clinically characterized by skeletal muscle weakness. This can be triggered by drugs, infections, and in rare cases by vaccines. During the COVID pandemic, de novo cases and exacerbations of myasthenia gravis due to viral infection have been documented. Although few cases related to COVID vaccination. A 69-year-old female patient with blurred vision, a clinic that began 10 days later after receiving first dose of COVID vaccine, and diplopia and right palpebral ptosis after the second dose, 30 days later. In the examination, Edrophonium test was clearly positive, treatment with pyridostigmine and prednisone was started and after 14 days the clinic showed improvement until the resolution of the symptoms There are few reports of exacerbations or triggers for the appearance of myasthenia gravis, a series of 27 cases has been published where there are outbreaks of immune-mediated diseases or the new appearance of autoimmune diseases, in which it is observed that the time of appearance of the outbreak was on average 4 days up to a maximum of 25 days. In conclusion, Myasthenia gravis is a rare complication of the BNT162b2 COVID-19 vaccine. Its potential severity and the current lack of knowledge of the real incidence after vaccination makes it necessary to maintain an attitude of vigilance in the face of symptoms that suggest it.

Development of SARS-Cov-2 Circulating Immune Complex Candidate, (CRCx) as A New Promising Vaccine Eliciting Broad Immune Response.

There is a need to develop a universal vaccine that can boost immunity to coronaviruses if some modifications in their structure occur. This is what we are dealing with nowadays: a virus that can mutate its structure, while immunity is standing still in facing the virus. We report on preclinical trials of CRCx 3 and CRCx 2 vaccine candidates in inducing an elevated level of positive neutralizing antibodies as well as a cellular immune response in an animal model to provide protection against SARS-CoV-2. Highly efficient protection against SARS-CoV-2 was obtained with three-dose immunization using 0.25 ml of CRCx vaccine with a 25-mm needle at 7-day intervals between successive injections. In addition, CRCx vaccine candidates exhibit efficient productivity and good genetic stability for vaccine manufacture. These results support the further evaluation of CRCx in a clinical trial.

Development of Mathematical Model for Vibration Accelerated Wound Healing

Chronic wounds substantially reduce the quality of life for millions of people worldwide. As a result, researchers have developed various treatments and therapies to reduce the time for a wound to heal. Mathematical models that help better understand and predict the wound healing process have also been developed. This paper presents and validates a mathematical model known as the vibration enhanced wound healing model (VEWH) that includes the effects of vibration treatment in the wound healing process. The model is based on existing models of cutaneous wound healing but includes the effects of vibration on blood flow, macrophages, chemoattractant, and fibroblasts. These parameters were derived from published data on vibration accelerated wound healing of healthy mice. The VEWH model is confirmed with published experimental animal data that show vibration can reduce the wound healing time by 8%. The model reveals that vibration primarily affects healing through the mechanotransduction of vibration by fibroblasts into greater production of extracellular matrix. Model simulations agree with the validation data, with optimal healing predicted to occur with frequencies between 5 Hz and 25 Hz.

Assessing Burn Patterns and Severity Using IR Visualization – A Case Study Approach

This investigation studies the potential use of infrared (IR) sensing technology to answer key questions of scalding. In particular, scalding incidents are frequently plagued by conflicting recollections, uncertain details, and litigation. Questions often relate to how a scalding spill occurred, how hot the liquid was, the direction of liquid flow, and the connection between burn patterns and spill patterns. Flow patterns, among others are sometimes, challenging to determine after a spill incident. Nevertheless, IR technology can be used for event reconstruction and can help identify the typical burn patterns that result from spills. Here, IR imaging is applied to common scald situations. The IR imaging provides temperature information that is continuous in both space and time and can be used with currently available burn models to predict burn depths and patterns. The IR images are used to generate a burn-depth map superimposed on the patient’s body. This study shows that IR imaging leads to reproducible results that can be used to predict burn-depth patterns based on situation specific spills.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
