Fecal transplantation: a rejuvenating cure for ageing?

Laura_Exden2022-07-11T11:03:34+02:0008 July 2022|That's your concern, The Science|Comments Off on Fecal transplantation: a rejuvenating cure for ageing?

More and more scientific papers are highlighting the health benefits of fecal microbiota transplantation (FMT). The administration of stool from a healthy individual into the digestive tract of a person with a pathology related to the gut microbiota has shown very interesting results. It is even recognised as a treatment for recurrent Clostridium difficile infection. But did you know that it offers hope for limiting the effects of ageing? Eternal youth has always fascinated humanity. In a society where we are gaining years of life thanks to medical progress, aging without looking old or being sick is the quest of [...]

COVID-19 & probiotics: PROTECT-EHC results published!

Laura_Exden2022-04-01T09:16:56+02:0001 April 2022|The Science|Comments Off on COVID-19 & probiotics: PROTECT-EHC results published!

In this article, we presented the PROTECT-EHC protocol. The aim of this American clinical study was to test the effects of Lactobacillus rhamnosus GG on the transmission of COVID-19 within the same household. The results are now published. A new strategy to fight COVID? For almost two years now, the coronavirus has been affecting our lives. One of the strategies proposed to limit its impact has been vaccination. Vaccination has been one of the strategies proposed to limit its impact. Although effective in limiting the severe symptoms associated with SARS-CoV-2, the uptake of vaccines has been limited. In addition, the immunity [...]

Coffee: a drink that impacts digestion and microbiota?

Laura_Exden2022-02-18T09:39:37+01:0018 February 2022|Digest, Non classé, That's your concern, The Science|Comments Off on Coffee: a drink that impacts digestion and microbiota?

Ground, bean, pod or capsule, coffee is one of the most consumed drinks in the world. However, is this drink beneficial or harmful to health, especially to the gut microbiota? Astrid Nehlig, research director at INSERM*, has carried out a review of the scientific literature published in Nutrients, on the impact of coffee on the gastrointestinal tract. No less than 194 publications were analyzed! In this article, we will only focus on its beneficial effects on digestion and the intestinal microbiota. Coffee to help you digest According to Astrid Nehlig's findings, moderate coffee consumption (3 to 5 cups per day according [...]

Microbiota and immune system: identification of a key protein

Laura_Exden2022-03-31T15:29:14+02:0007 January 2022|Immunity, The Science|Comments Off on Microbiota and immune system: identification of a key protein

It is now well established that the gut microbiota plays a role in our immunity. However, one question remains: how is the connection made? A recent study including in vitro and in vivo results provides the beginning of an answer. Our intestine, made up of a layer of epithelial cells, is home to a microbial community that lives in balance. This is the intestinal microbiota. This organ acts as a barrier, allowing the selective passage of molecules into the bloodstream. Nevertheless, some disturbing elements can unbalance this ecosystem. This disrupted balance, named dysbiosis, can lead to intestinal inflammation: the intestinal [...]

Rheumatoid arthritis: a link with the intestinal microbiota?

Laura_Exden2022-03-31T15:37:33+02:0012 November 2021|The Science|Comments Off on Rheumatoid arthritis: a link with the intestinal microbiota?

Dysbiosis of the gut microbiota may be linked to the development of rheumatoid arthritis (RA), according to a team of researchers. What is rheumatoid arthritis? RA is a chronic inflammatory disease affecting the joints. It is an autoimmune disease that progresses in flare-ups. Thus, the antibodies produced by the body will attack the synovial membrane of the joints. RA is characterized by joint deformation and destruction, joint pain, swelling and inflammation. It is a multifactorial disease, dependent on environmental, hormonal, immunological and genetic factors, although the exact origin of the disease is still unknown. However, a new component seems to interest [...]

Is the vaginal microbiota involved in the onset of recurrent miscarriage?

Laura_Exden2022-03-31T15:40:26+02:0001 October 2021|The Science, Women|Comments Off on Is the vaginal microbiota involved in the onset of recurrent miscarriage?

Often a taboo topic, miscarriage is nevertheless an ordeal for many women and couples. Generally unexplained, miscarriages could however find their origin in an imbalance of the vaginal microbiota. What is a miscarriage? This is a natural termination of pregnancy during the first 5 months. The majority of them take place in the first quarter. A miscarriage can be detected by: vaginal blood loss (or metrorrhagia); cramps in the lower abdomen (corresponding to uterine contractions); disappearance of the signs of pregnancy. Many women experience a miscarriage in their lifetime. Indeed, 23 million miscarriages occur each year worldwide, representing 15% of all [...]

PROTECT-EHC: the clinical trial linking probiotics and COVID-19 transmission

Laura_Exden2021-08-17T16:27:18+02:0003 September 2021|The Science|Comments Off on PROTECT-EHC: the clinical trial linking probiotics and COVID-19 transmission

PROTECT-EHC is a new clinical trial testing the effects of a well-known probiotic on the COVID-19 transmission within the same household. COVID-19 (or SARS-CoV-2) continues to mutate and spread around the world. Our lives are on hold, waiting to stop its spread and limit its impact on our health. The damage caused has been and remains dramatic, both in terms of human loss, associated diseases and financial costs. Strategies to mitigate the contamination and severity of COVID-19 infection are essential. One strategy considered: probiotics One strategy is to act on the composition of the intestinal microbiota via probiotic supplementation. Currently, 16 [...]

Can pollution impact our gut microbiota?

Laura_Exden2021-07-15T09:20:12+02:0009 July 2021|That's your concern, The Science|Comments Off on Can pollution impact our gut microbiota?

Pollution may disrupt the gut microbiota, according to a team of researchers at the University of Colorado Boulder. Air pollution has a negative impact on our health. It has been identified as the 5th leading risk factor for mortality worldwide. Indeed, it can be responsible for chronic diseases, especially respiratory diseases. However, our lungs are not the only ones poisoned by the air we breathe. The intestinal microbiota would also be. Pollution and microbiota: the first clinical trial Animal model work suggests that exposure to air pollutants may alter the microbiota composition. Armed with this observation, American researchers enrolled a hundred [...]

Are gut microbiota and skin linked?

Laura_Exden2021-08-18T10:00:15+02:0025 June 2021|Skin, The Science|Comments Off on Are gut microbiota and skin linked?

The intestinal microbiota has a central role in our health. We already know its unsuspected link with the brain and its impact on neurodegenerative diseases, stress, anxiety. However, the brain is not the only organ with which it works closely. Indeed, there is a new axis: the skin-gut axis. A Canadian research team has been working to prove this. The researchers observed whether UVB light had an impact on the gut microbiota composition. A clinical trial to prove the gut-skin axis A pilot study was conducted between February and April 2018 on 21 women with skin types ranging from I to [...]
