Storage of umbilical cord blood

Sang cordon ombilical bébé

For the first time in France, a couple has just been given authorisation to entrust a private company with the storage of umbilical cord cells from their unborn child, in view of a potential therapeutic need.

In its Order dated 21 November 2016, the Grasse court authorised the couple to “take and store haematopoietic cells from the umbilical cord and from the placental blood, along with cells from the cord and placenta (…) in light of duly justified therapeutic needs.”

Winner of the 2010 Inserm Honorary Prize, Eliane Gluckman, a haematologist at Saint Louis Hospital, Paris, an Inserm researcher, and a specialist in blood stem cell transplantation, was the first to have performed, in 1987, an umbilical cord blood transplant in a 6 year old child.

Cord blood is currently used to treat patients with blood diseases (leukaemias and lymphomas), and, for certain indications, replaces bone marrow.

Attacks and risks of post-traumatic stress

In a traumatic event, such as the attacks on Paris on 13 November 2015, and on Nice on 14 July 2016, the risk for victims and witnesses of developing post-traumatic stress disorder (PTSD) is high.

PTSD is characterised by several symptoms: the person relives the event in the form of recurrent memories, nightmares or flashbacks, avoids anything that reminds him/her of the moment, is in a constant state of alert, and shows difficulty in concentrating. Changes in mood may also occur.

At Inserm, there is ongoing active research to better identify the people most at risk of developing post-traumatic stress disorder, and thereby improve their care.

In the Phoenix study, which evaluates the impact of a trauma or chronic stress on the physical and mental health of 123 patients for a one-year period, work carried out by Isabelle Chaudieu, Inserm Unit 1061 “Neuropsychiatry: Epidemiological and Clinical Research,” is aimed at identifying biomarkers to predict PTSD. Her team is trying to determine whether the allostatic load might make it possible to predict the development of PTSD.

By collecting and analysing personal accounts from 1,000 volunteers over a ten-year period, the 13 Novembre programme (CNRS – Inserm), codirected by historian Denis Peschanski and neuropsychologist Francis Eustache, is aimed at studying the construction and evolution of memory after the attacks of 13 November 2015, and the interaction between individual and collective memory. The researchers will try to better understand the impact of traumatic shocks on the memory, and identify brain markers associated with resilience to trauma.

Yes, the time change has physiological effects

The Black Sun©Fotolia

On the night of Saturday 29 October to Sunday 30 October 2016, at 3 am it will be 2 am. This time change is not without effects on human physiology and health. When, in April 1784, Benjamin Franklin wrote in the Journal de Paris that getting up an hour earlier in winter would reduce the consumption of candles and reduce pollution, he was right. When he claimed that the new schedule would be difficult to endure for only two or three days because “Only the first step costs,” he was wrong.

The scientific literature shows that the time change can lead to sleep and alertness problems, road accidents, depression, suicide, and myocardial infarction.

The transition is more disruptive in winter for those who go to bed early. For Claude Gronfier, Inserm Researcher, “Among other things, the time change causes problems with sleep and attention. Children and older people are particularly affected, and take around a week to adapt to the new schedules.”

To find out all about the change in time, its history, its impact on health and how that works, contact Claude Gronfier.

Gastroenteritis is back in metropolitan France

Sentinelles

Sentinelles network’s bulletin of 19 October 2016

According to the Sentinelles network’s weekly bulletin of 19 October 2016, the incidence rate of acute diarrhoea reached epidemic levels in metropolitan France last week, with 155 cases observed in general medicine clinics per 100 000 inhabitants.

The Sentinelles network adds that the current level of gastroenteritis is higher than the mean level observed in previous years in the same period. The Grand-Est, Ile-de-France and Pays de la Loire regions are particularly affected, with respective estimated incidence rates of 297, 213 and 211 cases per 100,000 inhabitants.

 

The Sentinelles network is national surveillance system developed by Inserm and Pierre and Marie Curie University. Made up of 1,300 general practitioners and about a hundred private paediatricians, it has allowed the development of large databases on several diseases, for health surveillance and research purposes.

To obtain further information on gastroenteritis in France, you may contact Thierry Blanchon, Deputy Head of the Sentinelles network.

How fatigue influences our decision-making

To resist the temptation of a beer in order to save and buy a bike later? At the end of the day, fatigue would encourage us to choose the immediate reward instead. This is what is revealed by a study published in PNAS and conducted by Bastien Blain, a researcher at Inserm Unit 1127.

Behavioural experiments were carried out on 50 people with an average age of 24 years, divided into 3 groups. One group of participants had to solve complicated exercises for a period of over 6 hours. By comparison, the second group had to work on simple exercises, while the last group played video games or read articles. At regular intervals, the researchers asked all participants to choose between receiving a small sum of money immediately, or a larger sum of money later.

Results show that a prolonged cognitive task favours impulsive choice, and that this decision is linked to reduced activity in a region of the brain involved both in these exercises and in monetary choices.

In conclusion, several hours of intense work may lead us to choose the short-term reward instead of a greater, more long-term benefit. It is therefore better to avoid making an important decision, especially of a financial nature, at the end of the day.

Thursday 26 May 2016: National Day of Screening for Skin Cancer

Organised by the French National Union of Dermatologists (SNDV), and supported by the French National Cancer Institute (INCa), the 18th edition of the National Day of Screening for Skin Cancer will be held on Thursday, 26 May 2016, to highlight the risks of UV exposure, and to raise awareness about the measures for protecting oneself from this cancer, and for detecting it.

During this day, free screening consultations will be on offer throughout France.[1]

Although less common than carcinoma, melanoma is the most “serious” type of skin cancer, because of its propensity for rapid progression to the metastatic stages.

In 2015, melanoma was responsible for 14,325 new cases, and 1,773 deaths in France.[2]

At Inserm, research is actively underway to improve understanding of the mechanisms involved in metastatic spread, and to develop new therapeutic strategies.

Work done at Inserm Unit 981 by Caroline Robert, winner of the Inserm Research Prize 2015, has contributed to the development of immunotherapy and targeted therapies, major advances in the treatment of metastatic melanomas. Her team is currently focusing on the adverse effects of new drugs in order to develop more effective treatments.

Unemployment and health

In 2015, a study conducted by Pierre Meneton, entitled “Unemployment is associated with high cardiovascular event rate and increased all-cause mortality in middle-aged socially privileged individuals,” was published in the International Archives of Occupational and Environmental Health.

The results suggest that there may be an association between unemployment and poorer cardiovascular health, unlinked to other conventional risk factors, such as age.

Isolated case of bovine spongiform encephalopathy (BSE) in France

This Thursday, 24 March, the Ministry of Agriculture confirmed an isolated case of bovine spongiform encephalopathy (BSE), or mad cow disease, at a farm in Ardennes. The case was detected in a 5-year-old cow sent for rendering, “a method for processing animals that die on farms, and are therefore not intended for human consumption,” states AFP. In France, the last case of bovine spongiform encephalopathy dates back to 2011.

 

BSE is a prion disease that affected UK farms in the 1980s, and spread to Europe and the rest of the world. Feeding animals meat and bone meal contaminated with crushed carcasses resulted in the spread of BSE.

The appearance of a variant of Creutzfeldt-Jakob disease in humans in the UK and France, and then in many countries around the world in the 1990s, raised deep concerns among consumers who worried about the risk of transmission of the bovine prion to humans. The link between the BSE epidemic and the new variant of Creutzfeldt-Jakob disease in humans was easily established by researchers.

The ban on meat and bone meal, livestock surveillance and BSE testing are some of the measures that have been developed since then, in order to limit the risk of contamination.

What are the routes and mechanisms for transmission of a bovine prion to humans? What are the risks of secondary transmission? What are the consequences for health? How is the disease managed?

Sunday 14 February 2016: Heart Day

As the cause of 17.5 million deaths in 2012, cardiovascular diseases are the leading cause of mortality worldwide.[1] In France they are the second leading cause of mortality in men, and the leading cause in women.[2]

 

These diseases are a group of disorders of the heart and blood vessels, such as hypertension, coronary heart disease, cerebrovascular disease (stroke), peripheral arterial disease, heart failure, rheumatic heart disease, congenital heart disease and cardiomyopathy.

Heart Day, initiated by Alliance du Cœur and held on 14 February every year, the symbolic date of St. Valentine’s Day, is aimed at bringing together the general public, health professionals and public authorities for a national debate in order to combat cardiovascular diseases. On this occasion, many events will be held in three cities in France, Belfort, Paris and Strasbourg, on the theme “Every Woman’s Heart.”

See the programme on the Heart Day information website.
