A study published in the journal Science by a research team from Gustave Roussy, INSERM, INRA, AP-HP, IHU Médiaterranée Infections* and Paris-Sud University shows that prescribed antibiotics impair the efficacy of immunotherapy in cancer patients.

The French National Institute for Health and Medical Research (Inserm) and the Directorate of Research, Studies, Evaluation and Statistics (DREES) have published the preliminary results of the French National Perinatal Survey 2016. This report, based on a sample of births representing all births in France for the year 2016, presents the changes in the main perinatal indicators of health, medical practices and risk factors. It also describes the organization of healthcare in the country's 517 maternity units.

A research team in psychiatry at CEA-Neurospin, together with the Mondor Institute of Biomedical Research (INSERM) and the Henri-Mondor (AP-HP) university hospitals, has shown that a genetic variant associated with several psychiatric conditions alters a prefrontal-limbic network, which may increase the risk of developing schizophrenia or bipolar disorder. The results of this study were published online on October 2, 2017 in Journal of Neuroscience .

An epidemiological study carried out by Inserm on families from the EDEN cohort (500 boys born between 2003 and 2006 and their mothers) shows that exposure during pregnancy to certain phenols and phthalates is associated with behavioral problems in boys between 3 and 5 years of age. The most worrying compounds in this respect are bisphenol A, triclosan and dibutyl phthalate (DBP). The results of this study have recently been published in Environmental Health Perspectives .

Between 2010 and 2012, 256 women died in France from causes linked to pregnancy, labor, or following childbirth, amounting to 85 such cases a year. Although inequalities remain, improvements have been observed in the provision of labor care, with the death rate from hemorrhage halving.

A new study led by Inserm researchers from Irset, the Research Institute for Environmental and Occupational Health, [1 ] shows for the first time in humans that simultaneous exposure to endocrine disruptors exacerbates the effects observed from exposure to each chemical independently. This study focused principally on the human fetal testes and the potential consequences of these mixtures on development of the reproductive system, as the selected chemicals inhibited testosterone production. These results were published in Environmental Health Perspectives .

Scientists at the Institut Pasteur, CNRS and Inserm, together with a team from Switzerland*, have shown that the bacterial pathogen Legionella pneumophila (the causative agent of Legionnaires' disease or legionellosis) has developed a specific strategy to target the host cell mitochondria, the organelles in charge of cellular bioenergetics.

How do we know whether a patient is conscious when he or she is unable to communicate? According to an Inserm study conducted in 127 patients aged 17 to 80, changes in heartbeat in response to sound stimulation is a good indicator of state of consciousness. This is what Inserm researcher Jacobo Sitt and his team, based at the Brain & Spine Institute (ICM) at Pitié-Salpêtrière Hospital, AP-HP, demonstrate in an article published in Annals of neurology. This easy-to-perform examination complements the existing tests and enables finer predictive diagnosis, useful for both doctors and the patient's loved ones.

The creation of accelerators of technological research (ART) is a priority of Inserm's strategic plan. On October 12, 2017, Inserm launches its second ART, this time devoted to 3D Bioprinting, in Bordeaux. It is the only tech unit to use the three principal 3D biological printing technologies: laser, ink jet and micro-extrusion. Within the ART, researchers and engineers work together to as quickly as possible transform the fruits of research into technological innovation.

Adenomatous polyposis coli (APC) is a gene whose mutations are associated with a rare, hereditary form of colorectal cancer known as familial adenomatous polyposis. Research led by scientists at the Institut Pasteur and Inserm have recently demonstrated that mutations to this gene do not only lead to the emergence of colon polyps; they also harm the immune system, leaving it unable to tackle inflammation of the colonic mucosa. This dual impact supports the development of cancer. The finding, published in the journal Cell Reports on October 3rd, 2017, advances scientific knowledge on the development mechanisms of colorectal cancer.

Associated with an aging population and the development of metabolic syndrome, atherosclerosis is a leading cause of death worldwide. Researchers from Inserm Unit 970, the "Paris Cardiovascular Research Center" (Inserm/Université Paris Descartes), have succeeded in revealing the mechanisms underlying the formation of atherosclerotic plaques.

The ANRS consortium "Humanized Mouse Models for Viral Hepatitis"1, made up of 6 teams of researchers, has developed a mouse model for studying the interaction between the immune system and the liver following infection by the hepatitis B virus. This research, coordinated by Dr. Hélène Strick-Marchand (Inserm joint unit 1223, "Physiopathology of the Immune System", Institut Pasteur), responds to a real lack of animal models for studying this disease and thus opens up the possibilities for evaluating new therapeutic strategies. These

A recent study conducted by Anne Giersch and her team of researchers (Inserm Unit 1114 /University of Strasbourg) showed that some people with schizophrenia are unable to perceive and anticipate the passage of time. These results, published in the Scientific Reports journal, also reveal a link between fragile temporal prediction and minimal self disorders (self-perception, "I am here, now").

The origin, development, and characteristics of two types of testicular macrophage have been described by a CNRS team at the Centre d'Immunologie de Marseille-Luminy (CNRS / INSERM / Aix-Marseille University). To elucidate the nature of these immune cells, the researchers used a novel cell tracing method. Their findings were published on August 7, 2017, in the Journal of Experimental Medicine, and are of fundamental importance. They may help understand certain kinds of infertility in men and find new treatments for them.
