During a 2-month mission in Southeast Asia, including numerous stopovers in coastal cities, the crew of a frigate of the French Navy received doxycycline for antimalarial prophylaxis. Adherence to this chemoprophylaxis was evaluated with an anonymous questionnaire distributed at the end of the malaria exposure period. The response rate was 74 % (72 crew members). Among them, 67 sailors felt they had received clear information about the risks of malaria. Overall, 19 (27 %) respondents reported adherence (one forgotten pill, by no more than 15 days), 18 (25 %) irregular adherence (one or more pills forgotten weekly or stopped during the mission), and 35 recognized that they had not taken the treatment...

BACKGROUND: Red blood cell (RBC) storage in blood banks is not exempt from cellular injury. Alterations not observed on RBCs freshly isolated from units can rapidly appear in circulation. The transfusion of old blood units, even if this is a controversial issue, could therefore have adverse effects on the recipient. We wanted to determine the respective effects of storage duration and recipient plasma on RBCs for transfusion into patients with severe sepsis. STUDY DESIGN AND METHODS: Eleven stored RBC units were sampled at various time points, approximately Days 3 to 8 (referred to as fresh RBCs) and Days 38 to 42 (old RBCs) and tested in coincubation experiments with plasma obtained from 13 patients with severe sepsis and 17 healthy donors as controls...

BACKGROUND/PURPOSE: Bioabsorbable vascular scaffolds (BVS) are made from a radiolucent material. Their multiple implantations on a single long diffused segment requires a specific technique with imaging magnification, which could cause an increase in dose delivered during percutaneous coronary intervention (PCI) procedure. We aimed to identify differences in radiation dose, fluoroscopy and procedural times in Hybrid DES+ multiple BVS (Absorb, Abbott Inc., USA) implantation (hybrid metal/scaffold jacket) versus multiple III generation Drug-eluting stents (DES) (full-metal jacket) in patients with long and diffuse coronary artery disease of the left anterior descending (LAD) coronary artery...

The sturgeon is a highly endangered fish mostly due to over-fishing, habitat destruction, and water pollution. Nonylphenol (NP), propranolol (PN), and diethylstilbestrol (DES) are multifunctional xenobiotic compounds used in a variety of commercial and industrial products. The mechanism by which these xenobiotic compounds interfere with fish reproduction is not fully elucidated. This study assessed the effect of NP, PN, and DES on motility parameters, membrane integrity, and oxidative/antioxidant status in sterlet Acispenser ruthenus spermatozoa...

BACKGROUND: Cold tolerance is a key determinant of temperate insect distribution and performance. Chill-susceptible insects lose ion and water homeostasis during cold exposure, but prior cold acclimation improves both cold tolerance and defense of homeostasis. The mechanisms underlying these processes are mostly unknown; cold acclimation is thought to enhance ion transport in the cold and/or prevent leak of water and ions. To identify candidate mechanisms of cold tolerance plasticity we generated transcriptomes of ionoregulatory tissues (hindgut and Malpighian tubules) from Gryllus pennsylvanicus crickets and compared gene expression in warm- and cold-acclimated individuals...

Taher Al Jishi, Consolato Sergi
Diethylstilbestrol (DES) was an orally active estrogen prescribed to the pregnant women to prevent miscarriages. DES is known as a 'biological time bomb' and long-term effects of DES have been recorded in the mothers exposed to DES and their offspring (DES-daughters and DES-sons). Adverse pregnancy outcomes, infertility, cancer, and early menopause have been discovered in women exposed to DES, and some events occur in their offspring and subsequent generations. An increased risk of breast cancer is not limited to the DES-exposed daughters...

INTRODUCTION: Aconite poisoning is relatively rare but is frequently complicated by ventricular dysrhythmias, which may be fatal. Molecular basis of aconite alkaloid ventricular arrhythmogenicity: Aconite exerts its toxic effects due to the presence of an admixture of alkaloids present in all parts of the plant. The major target of these aconite alkaloids is the fast voltage-gates sodium channel, where they cause persistent activation. This blockade of the channel in the activated state promotes automaticity within the ventricular myocardium and the generation of ventricular arrhythmias...

BACKGROUND: In the Western world, between 1940 and 1970, more than 2 million people were exposed in utero to diethylstilbestrol (DES). In exposed individuals, and in their descendants, adverse outcomes have been linked to such exposure, including cancers, genital malformations, and less consistently, psychiatric disorders. We aimed to explore whether prenatal DES exposure would be associated with DNA methylation changes, and whether these epigenetic modifications would be associated with increased risk of psychosis...

Treatment of coronary artery disease has made strides over the last decades. Development of drug eluting stents (DES), coated with a polymer layer and an anti-proliferative drug to reduce neointimal hyperplasia, has reduced the incidence of in-stent-restenosis relative to treatment with bare metal stents. Patients treated with first generation DES more likely suffer from (very) late events which can be cause by the permanent presence of a polymer. Therefore second generation DES with more biocompatible coatings, and third generation DES, with very thin struts coated with biodegradable polymers, were developed...

Children who endure multiple victimization experiences, or "polyvictims," are vulnerable to maladaptive outcomes. Yet, little research exists evaluating the relationship between childhood polyvictimization and disordered eating symptoms (DES) in emerging adulthood. The current study examines the relationship between childhood polyvictimization and DES in emerging adults. Data were collected from 288 participants across two universities using online self-report measures. Hierarchical regression analyses revealed a significant positive relationship between number of childhood victimization experiences and DES in young adulthood (ß=0...

Studies evaluating dermal exposure to pesticides among applicators in tropical countries have largely been conducted using the patch dosimetry and hand wiping/washing techniques. This study used the more accurate whole-body dosimetry technique to evaluate dermal exposure to chlorpyrifos among applicators on rice farms in Ghana. The exposure levels were plotted as Cumulative Probability Distribution (CPD). Total Dermal Exposure (TDE) of chlorpyrifos among the median exposed and the 5% highly exposed groups during a spray event were 24 mg and 48 mg, respectively...

Bisphenol-A (BPA) is a component of polycarbonate and other plastics to which humans are regularly exposed at low levels. BPA is characterized as an endocrine disruptor because of observations of its estrogenic activity in various experimental models. We have previously shown evidence of disrupted hypothalamic feeding circuitry and leptin sensitivity in adult BPA-exposed animals subjected to a high-fat diet, but because these animals were already exhibiting a diet-induced obese phenotype, we could not rule out the possibility that these observations were simply consequences of the obesity, not a preexisting phenotype produced by BPA exposure...

This paper presents two cases of women who had extensive vaginal adenosis from prenatal DES exposure, extending almost halfway down the vaginal canal. Both women were followed for decades with annual exams and Pap smears until after menopause. Clinical examination in both cases initially showed an absent pars vaginalis of the cervix, vaginal adenosis, and shallowness of the fornices. Several decades of annual exams showed these stigmata of DES exposure gradually disappear as the upper vagina progressively contracted...

Adenocarcinoma of cervix constitutes about 10-15% cases of carcinoma cervix. Clear cell variant is even a rarer variant of adenocarcinoma. It rarely occurs in the paediatric age group and a known risk factor is in utero exposure to diethylstilbestrol (DES). We report here a case of primary cervical tumour in a 1-year-old girl, which was initially suspected to be an embryonal rhabdomyosarcoma botryoides. Histopathology with immunohistochemical analysis revealed clear cell adenocarcinoma. There was no maternal history of DES intake during pregnancy...

A systematic review (SR) and meta-analysis cannot provide the endpoint answer for a chemical risk assessment (CRA). The objective of this study was to apply SR and meta-regression (MR) analysis to address this limitation using a case study in cardiovascular risk from arsenic exposure in Vietnam. Published studies were searched from PubMed using the keywords of arsenic exposure and cardiovascular diseases (CVD). Random-effects meta-regression was applied to model the linear relationship between arsenic concentration in water and risk of CVD, and then the no-observable-adverse-effect level (NOAEL) were identified from the regression function...

Clear cell adenocarcinoma of the cervix (CCAC) is a rare type of gynecological cancer. The risk factors and pathogenesis have yet to be clearly determined. This is a case report of a 19-year-old woman, who was never exposed to DES from her mother, who had gone for an examination for vaginal bleeding. A polypoid mass measured at 3 cm presenting in her cervix was discovered. Histological diagnosis following cervical biopsy proved the tumor to be a clear cell carcinoma. The patient was then referred to our hospital...

Both diethylstilbestrol (DES, an environmental estrogen) and flutamide (FLU, an anti-androgen) are found to impair spermatogenesis by disrupting hypothalamic-pituitary-gonadal (HPG) axis and altering androgen levels through different mechanisms/modes of action in fish with poorly understood underlying mechanisms. Furthermore, it is not known whether and how a combined exposure of DES and FLU has a stronger effect than the compounds alone. In this study, male zebrafish adults were exposed to DES, FLU and their combination (DES+FLU) for 30days, and their effects on histological structure and sperm count in testis, androgen level in plasma, as well as the mRNA levels of genes involved in HPG axis, meiotic regulation and apoptosis were analyzed...
