Several prescription meds linked to an increased risk of death
Anti-anxiety drugs and sleeping pills have been linked to an increased risk of death, according to new research from the University of Warwick. The large study shows that several anxiolytic (anti-anxiety) drugs or hypnotic drugs (sleeping pills) are associated with a doubling in the risk of mortality. Although these findings are based on routine data and need to be interpreted cautiously, the researchers recommended that a greater understanding of their impact is essential.

Women exposed to DES in utero during critical periods of reproductive tract development developed several types of reproductive tract abnormalities, as well as an increased incidence of cervical-vaginal cancer later in life
2009 Study Abstract
Ovarian Follicular Development and the Environment
The ovarian follicle is the functional unit of the ovary and is comprised of an oocyte surrounded and supported by the somatic granulosa and theca cells (28). The health of the follicle can impact the health of the woman as well as the health of her offspring. For example, decreased numbers of follicles, multiple eggs per follicle and incomplete follicular development can all result in decreased fertility. The precise mechanisms involved in early ovarian follicle formation are not known, but are essential in organizing the fetal ovary and establishing the postnatal follicle number that will provide the female with sufficient oocytes for a lifetime of fertility.
Estrogen and activin are two known factors that play an important role in regulating oocyte and follicle development and function and aberrant development and ovarian pathologies are observed in mice exposed to neonatal estrogen or activin. Neonatal exposure of rats to estradiol benzoate has been show to delay follicle and interstitial development. Neonatal exposure to diethylstilbestrol (DES) or the natural estrogen estradiol (E2) results in lack of corpora lutea in adult mice, suggesting that these effects persist beyond reproductive tract development and impact fertility in the adult. Neonatal exposure to DES, E2, or the phytoestrogen genistein also induces formation of multi-oocytic follicles in mice – an effect that is also reported in alligators exposed to environmental estrogenic contaminants. Additionally, activin administered during the critical, postnatal period of primordial follicle formation changes the number of postnatal follicles. Current mechanistic studies are exploring whether neonatal estrogen exposure alters activin signaling in the ovary; preliminary findings of decreased activin subunit gene expression and impacted activin signaling in the mouse ovary support this hypothesis.
Studies have now been extended beyond DES to demonstrate that other environmental estrogens reprogram gene expression in the uterus : exposure to genistein and BPA during the period of maximum sensitivity to developmental programming induces the expression of the estrogen-responsive genes calbindin and progesterone receptor. Neonatal BPA exposure attenuated estrogen-responsive genes whereas genistein exposure induced an even higher level of estrogen responsiveness than DES exposure. In contrast to DES, exposure to these environmental estrogens does not disrupt ovarian function in adult females, which continue to cycle normally.

The Chemicals Health Monitor aims to be your online source for the link between chemicals and diseases
” The Health and Environment Alliance (HEAL) has today re-launched its Chemicals Health Monitor (CHM), a revived online service consisting of a revamped website and newsletter as well as new social media tools, all available in English and German.
HEAL provides this monitoring service with the aim of improving public health by promoting support for more protective regulation of hazardous chemicals in Europe and beyond. The project encourages public health and health professional groups to use and share educational resources to inform patients and the public.
Many of the chemicals to which people are exposed daily have never been tested for their effects on human health and the environment. When studies have been done, the test results may not be publicly available. Meanwhile, more and more studies link chemical exposure to a range of specific chronic conditions. The research suggests that due to their exposure, families and individuals may be more prone to obesity and diabetes, more likely to suffer from cancer, and more likely to face infertility. Healthcare systems are struggling to cope with rising rates of these conditions.
Although EU laws set high and innovative standards, significant gaps nonetheless remain, particularly regarding the effects of multiple concurrent exposures and of long-term, cumulative exposures. The Chemicals Health Monitor provides the latest authoritative, independent information linking chemical exposure to chronic health problems, which is developed with the help of public interest expertise.
HEAL’s ultimate goal in providing such a service is to inform the public and to mobilise partnerships in support of EU policies that protect health. In particular, HEAL seeks precautionary action to prevent exposure to toxic chemicals and effective implementation of the EU chemicals law, REACH.”

Les professeurs Bernard Debré et Philippe Even ont rué dans les brancards
Après les affaires de l’hormone de croissance, du Vioxx, de l’Isoméride du Mediator, et de plusieurs médicaments retirés du marché en quelques mois, une véritable, mais salutaire inquiétude s’est manifestée dans la population concernant l’utilité et les risques des traitements. La publication soudaine de listes de médicaments “sous surveillance renforcée”, dont beaucoup, inutiles ou dangereux, devraient avoir disparu depuis longtemps, souligne la timidité ou l’incompétence des pouvoirs publics et a fait monter d’un cran l’anxiété des patients. Les professeurs Even et Debré ont donc décidé de passer en revue les 4.000 médicaments sur le marché et d’identifier ceux qui sont efficaces, ceux qui le sont moins, ceux qui ne le sont pas du tout et, parallèlement, d’analyser leur degré de toxicité éventuelle intrinsèque et celle qui pourrait résulter des interactions entre eux, de l’âge des malades et des pathologies associées et préciser quel pays les a découverts, leur prix et leur coût pour la Sécurité Sociale. Ce guide, écrit pour les malades et parfois les médecins généralistes, ne peut évidemment répondre dans le détail à toutes les questions, mais il peut alerter, aider et, en cas de doute, conduire à consulter son médecin. Il devrait aussi aider les politiques à revoir et contrôler réellement le monde délirant des médicaments, ses milliers de médicaments inutiles, ses centaines dangereux.
New clues suggesting autism could be detected before birth
Researchers found new clues suggesting autism could be detected before birth ; their study gives clear and direct new evidence that autism begins during pregnancy. The researchers analyzed 25 genes in post-mortem brain tissue of children with and without autism. These included genes that serve as biomarkers for brain cell types in different layers of the cortex, genes implicated in autism and several control genes. Patches of unusual cell development was found in 10 samples.
In their small, explorative study – Patches of Disorganization in the Neocortex of Children with Autism – researchers found focal disruption of cortical laminar architecture in the cortexes of a majority of young children with autism.

Finding medical records showing that DES was prescribed during pregnancy can be very difficult…
Can you understand your doctor’s handwriting? For DES daughters, finding medical records showing that their mums were prescribed DES during pregnancy can be very difficult. If the doctor has retired or died, another doctor may have taken over the practice as well as the records or if the records are found they may just be unreadable …!
A cause de son exposition in utero au Distilbène, Stéphanie souffre de problèmes de stérilité et de malformations utérines qui l’ont notamment privée du bonheur de donner la vie. En 2005, elle engage une procédure judiciaire contre le laboratoire UCB Pharma qui commercialisait le DES. Son procès n’aura pas lieu car UCB Pharma fait annuler la demande d’expertise médicale en appel. Puis, en 2009, la Cour de Cassation annonce qu’il est interdit de faire appel d’une telle demande. Le dossier de Stéphanie peut donc être plaidé et jugé. Mais la lenteur de la justice française la contraint à attendre cinq ans de plus pour que le procès s’ouvre enfin.
Trois semaines après la victoire de Sylvie Le Cossec, le tribunal de Nanterre a annonçé que le rendu des délibérés pour Stéphanie aura lieu le 22 mai prochain.
DES is but one example of how exposure to EDCs can disrupt developing organ systems and cause abnormalities, many of which only appear much later in life or in the subsequent generation, such as endometriosis, fibroids and breast, cervical and uterine cancer in women; poor sperm quality and increased incidence of cryptorchidism and hypospadias in men; and subfertility and infertility in men and women.
