La digitalisation, une Urgence économique.

 L’absence des cafés à stimulé la culture digitale des tunisiens! 

le confinement de lutte contre le CVID-19 à stimulé les tunisiens, qui foncent directement sur le numérique avec leur faible connaissance et habitude, c’est une bonne nouvelle, malgré les faible moyens et connaissance.  parce que c’est le pas nécessaire à l’apprentissage dans la  pratiques de l’internet.  l’usage des termes et langage de programmation ne sont plus indispensable.  l’État doit participer et encourager les projets du digitalisation en Tunisie.

« Nous accusons en Tunisie un retard de 15 à 20 ans dans les technologies, le monde nous a dépassé » a-t-il regretté, indiquant que « depuis l’indépendance jusqu’aux années 2000, l’Etat a misé sur l’intellectuel en l’absence de richesses naturelles mais qu’au cours de la dernière période, l’on s’est plus préoccupé de politique ».

En absence de protocole, débrouilliez vous contre le COVID-19: Vitamine C

vitamine c

C’est une molécule alimentaire ,elle n’est pas un médicament. Elle doit être consommé toute le long de la vie humaine , car l’organisme humain ne le produit pas. C’est antioxydant , indispensable, à l’immunité humaine .

Le Dr Richard Cheng, médecin à Shanghaï,

pour les adultes 5 à 10 gr vitamine C pure en poudre / jour – 2 ou 3 prises, avec de l’eau tiède ou froide.
les enfants de moins de 10 ans, 3 à 5 gr / jours .
ils renforcent le système immunitaire et préviennent les virus dont le Coronavirus.

Can Vitamin C Prevent and Treat Coronavirus ?

Source: MedicineNet Health News

In a mad dash to discover effective treatment for the novel coronavirus, doctors and scientists are testing existing antivirals, antimalarials, monoclonal antibodies, and other medications against COVID-19. Now Chinese teams are adding vitamin C to the list of potential therapies.

ZhiYong Peng, MD of the Department of Critical Care Medicine at Zhongnan Hospital of Wuhan University recently registered a phase 2 clinical trial on ClinicalTrials.gov to test the efficacy of vitamin C infusions for the treatment of severe acute respiratory infection (SARI) associated with the novel coronavirus.

The study description notes that vitamin C is an antioxidant that may help prevent cytokine-induced damage to the lungs. Cytokines are small proteins released by cells, which trigger inflammation and respond to infections, according to MedicineNet author William C. Shiel Jr., MD, FACP, FACR. Severe lung inflammation with COVID-19 may result in respiratory distress and even death.

The clinical trial description states that vitamin C reduces the inflammatory response, and both prevents and shortens the duration of the common cold. The description further states that insufficient vitamin C is related to an increased risk and severity of influenza infections. The team aims to see if vitamin C has similar effects against viral pneumonia associated with COVID-19.

However not all experts agree. MedicineNet content reviewed by Carol DerSarkissian, MD states, “Your immune system does need vitamin C to work right. But extra won’t help you avoid a cold. It may make it go away faster or not feel as bad – if you were taking it before you got sick.”

Currently, there are no effective targeted antiviral medications for COVID-19. The main treatment consists of supportive therapy to manage symptoms.

Participants in the experimental group will receive 24 grams of IV vitamin C per day for 7 days. That’s more than 260 times the Daily Value (DV) for vitamin C for adults and children age 4 years old and up, which is 90 mg per day.

In a series of YouTube videos released within the last two weeks, Richard Cheng MD, PhD, Chinese Edition Editor of the Orthomolecular Medicine News Service states there are at least three clinical trials in China studying the effects of high-dose IV vitamin C for the treatment of COVID-19. He mentions the Shanghai Medical Association has released an expert consensus statement on the comprehensive treatment of COVID-19 where they endorse the use of high-dose IV vitamin C for the illness.

To the best of his knowledge, Dr. Cheng said the so-called “Shanghai Plan” published on March 1 is the first and only official government guideline for using vitamin C for something as serious as the novel coronavirus. He said there is a push to get additional Chinese hospital groups to study oral liposomal vitamin C for treatment of the virus because oral forms can be administered rapidly and widely to large numbers of affected patients.

Dr. Cheng states that the principle investigator of the first high-dose IV vitamin C trial in China has told him that the preliminary results of the study are promising. The investigator said the administration of 24 grams per day to COVID-19 patients leads to significant reductions in inflammation. Dr. Cheng said this is notable because massive inflammation in the lungs and potentially other organs may be fatal in the illness.

MedicineNet author Betty Kovacs Harbolic MS, RD adds that vitamin C is generally safe but, “Large doses of vitamin C may cause stomach upset and diarrhea in adults and have been reported to cause kidney stones.”

Will vitamin C be effective to prevent and treat novel coronavirus? Hopefully, ongoing studies will provide the answer. Follow the guidance of your health care professionals if you have questions about vitamin C or other supplements. In the meantime, take the recommended precautions to keep yourself and loved ones safe from the virus, including avoiding close contact with those who are sick and washing your hands frequently. Seek medical attention if you develop fevercoughing, and shortness of breath.

How Do the COVID-19 Coronavirus Tests Work ?

Tests for coronavirus may use two methods to detect the SARS-CoV-2 virus, the cause of COVID-19 disease, a debilitating and potentially deadly viral pneumonia

The tests are: 

  • genomic detection-based (molecular)
  • immunoglobulin detection-based (serology)

How do the gene tests for the COVID-19 coronavirus work?

The first and most prevalent method to detect the virus in individuals is based on detecting genetic material specific to SARS-CoV-2 viruses in a person’s nasopharyngeal secretions.

Although tests kits have a wide variation in their procedures (swabs of oral and/or of nasal surfaces, differences in solutions to transfer the swabbed tissue to, time and place to run the subsequent test reagents, for example), they all use methods that detect a specific part of the viral genome.

Here is an example of how one test system accomplishes this:

  • Swabbed tissue is loaded into a standard reaction vial
  • Reagents (the general term for additional chemicals needed in such tests) break open viruses to expose viral genome (RNA) to other reagents like synthesized RNA that binds to a specific small part of the viral RNA
  • This small bound-up strand of viral genome and reagent is then replicated many times (in some tests, up to a billion times!) over minutes to hours
  • Then, at the same time, another reagent specifically binds to each replicated genetic complex.
    • This reagent has a bounded marker that when enough replicated complexes are made, the machines can detect the attached marker. 
    • For example, the marker may be designed to glow with fluorescence, which the machine can pick up on its sensors.
  • Depending on how many viruses are present in the sample, positive results may occur (depending on the test used) in minutes to days
  • Conversely, if the test detects no viral material after a fixed time (minutes to days), the result is a negative test

What do the results of the COVID-19 coronavirus gene test mean?

The qualitative results from these tests are either the person is infected with SARS-CoV-2 and considered to be able to transmit the disease (a positive test) or is negative for the virus. 

This test cannot tell whether a person is immune from past infection or has yet to be exposed and is still in danger, however.

What are immunoglobulin detection-based tests for COVID-19 coronavirus?

Immunoglobulin detection tests are based on the qualitative detection of IgM and IgG that are specifically generated by the body in response to SARS-CoV-2 infection. 

IgM is usually the first, specific antibody type generated by the body in response to infection. Then, the IgG antibody type is generated and replaces IgM as the predominant antibody in the response to infection. 

IgM and IgG fight infections by targeting specific antigens on the surface of the SARS-nCoV-2 virus. 

In general, immunoglobulin tests use specific viral antigens to detect the IgM and/or IgG antibodies against those antigens.

Here is a sample of how the test works:

  • Collect 2-3 drops of fresh blood/serum or plasma and place it in a sample container and place 2-3 drops of provided buffer in the same container (cassette)
  • The cassette allows the diluted sample to move through the cassette by capillary action
  • The cassette has labeled SARS-CoV-2 antigen that may  bind chemically with either IgM or IgG; thus, forming an antigen/antibody complexes of antigen/IgG and/or antigen/IgM   
  • After that reaction, the antigen/antibody product passes over anti-IgM and anti-IgG antibodies that are immobilized in a line within the cassette
  • The anti-IgM and/or anti-IgG then will capture the specific complex and signal a result (a red line) if either complex is bound to the immobile anti-IgM or anti-IgG 
  • The results need to be read after 10 minutes and no more than 15 minutes (the test resembles a home pregnancy test in this respect.) 
  • A third line is a control line; it indicates that the test is working properly

What do the COVID-19 immunoglobulin test results mean?

A total of three detection lines are possible, the control with (C) line appearing when sample has finished flowing through the cassette, indicating the test is complete. 

The following are what the results mean:

  • Negative Result: If only the quality control line (C) appears and the detection lines G and M are not visible, then no novel coronavirus antibody has been detected and the result is negative.
  • Positive Result, IgM only: If both the quality control line (C) and the detection line M appears, then the novel coronavirus IgM antibody has been detected and the result is positive for the IgM antibody.
  • Positive Result, IgG only: If both the quality control line (C) and the detection line G appears, then the novel coronavirus IgG antibody has been detected and the result is positive for the IgG antibody.
  • Positive Result, IgG and IgM: If the quality control line (C) and both detection lines G and M appear, then the novel coronavirus IgG and IgM antibodies have been detected and the result is positive for both the IgG and IgM antibodies.

Immunoglobulin tests for COVID-19 cannot confirm the presence of the virus in your system. It can only tell whether you have been exposed in the past or if you have never been exposed to SARS-CoV-2. Consequently, it should only be used alone as a screening test and should be used in tandem with a genetic-based test to determine a complete status. Genetic testing is the gold standard for COVID-19 diagnosis.
