A French community-based intervention for parents of French-Canadian children with behavior problems: The EQUIPE program.

OBJECTIVES: Behavior problems are one of the most common reasons for seeking mental health services in pediatric populations. The objectives are to evaluate the effects of the EQUIPE program (Étude Québécoise d'Intervention pour les Parents d'Enfants avec des problèmes de comportement) and to analyze the impact of the severity of behavior problems and of parental characteristics. METHODS: This program was translated from the Community Parent Education Program. The effects of EQUIPE, as compared to a control group, were evaluated by using Child Behavior Checklist and Parent Stress Index questionnaires before (T0) and after the intervention program (T1), and at 6 (T2) and 12months (T3) follow-up visits. RESULTS: In total, 533 participants were enrolled in intervention (n=465) (with "severe" or "mild" subgroups according to CBCL-T score) and a control group (n=68). In the two groups, the results showed a statistically significant decrease in Child Behavior Checklist and Parent Stress Index total scores at T1, T2 and T3, with the exception of Child Behavior Checklist total scores in the control group at T2. In the intervention group Child Behavior Checklist total scores were significantly higher in the "severe"; which was not the case for Parent Stress Index total scores at T2 and T3. DISCUSSION: Socioeconomic characteristics, family details, parental medical history and the age of the children appeared to influence changes in Child Behavior Checklist and Parent Stress Index total scores. CONCLUSION: The EQUIPE program is an effective intervention for reducing behavior problems and parents' stress in a French-Canadian population.

Oral Condition and Incident Coronary Heart Disease: A Clustering Analysis.

Poor oral health has been linked to coronary heart disease (CHD). Clustering clinical oral conditions routinely recorded in adults may identify their CHD risk profile. Participants from the Paris Prospective Study 3 received, between 2008 and 2012, a baseline routine full-mouth clinical examination and an extensive physical examination and were thereafter followed up every 2 y until September 2020. Three axes defined oral health conditions: 1) healthy, missing, filled, and decayed teeth; 2) masticatory capacity denoted by functional masticatory units; and 3) gingival inflammation and dental plaque. Hierarchical cluster analysis was performed with multivariate Cox proportional hazards regression models and adjusted for age, sex, smoking, body mass index, education, deprivation (EPICES score; Evaluation of Deprivation and Inequalities in Health Examination Centres), hypertension, type 2 diabetes, LDL and HDL serum cholesterol (low- and high-density lipoprotein), triglycerides, lipid-lowering medications, NT-proBNP and IL-6 serum level. A sample of 5,294 participants (age, 50 to 75 y; 37.10% women) were included in the study. Cluster analysis identified 3,688 (69.66%) participants with optimal oral health and preserved masticatory capacity (cluster 1), 1,356 (25.61%) with moderate oral health and moderately impaired masticatory capacity (cluster 2), and 250 (4.72%) with poor oral health and severely impaired masticatory capacity (cluster 3). After a median follow-up of 8.32 y (interquartile range, 8.00 to 10.05), 128 nonfatal incident CHD events occurred. As compared with cluster 1, the risk of CHD progressively increased from cluster 2 (hazard ratio, 1.45; 95% CI, 0.98 to 2.15) to cluster 3 (hazard ratio, 2.47; 95% CI, 1.34 to 4.57; P < 0.05 for trend). To conclude, middle-aged individuals with poor oral health and severely impaired masticatory capacity have more than twice the risk of incident CHD than those with optimal oral health and preserved masticatory capacity (ClinicalTrials.gov NCT00741728).

A 6.78-MHz Robust WPT System with Inductive Link Bandwidth Extended for cm-Sized Implantable Medical Devices.

This paper presents a new technique to design a robust inductive link for Wireless Power Transmission (WPT) to centimeter-sized (cm-sized) Implantable Medical Devices (IMDs). The consequence of this methodology is the bandwidth extension of utilized link to maximize both Power Delivered to Load (PDL) and Power Transfer Efficiency (PTE). Design, circuit implementation, and In-vivo validation experimental results are reported. Different conditions of tests, including three misalignment experiments, are performed with the proposed WPT system to prove the concept of a robust inductive link. The geometry of the Transmitter (Tx) and Receiver (Rx) coils are considered as well as the operating frequency (fp) of the WPT system. The Tx and Rx coils are crafted in a circulated shape with the diameters of 5 and 2.5 cm, respectively. Achieved PTE and PDL are in the range of 0.82%-25.7% and 44.4mW-720mW, respectively. The distance between Tx and Rx coils varies in the range of 1.5 to 4cm.

Periodontitis and Cardiovascular Diseases. Consensus Report.

Background: In Europe cardiovascular disease (CVD) is responsible for 3.9 million deaths (45% of deaths), being ischaemic heart disease, stroke, hypertension (leading to heart failure) the major cause of these CVD related deaths. Periodontitis is also a chronic non-communicable disease (NCD) with a high prevalence, being severe periodontitis, affecting 11.2% of the world's population, the sixth most common human disease. Material and Methods: There is now a significant body of evidence to support independent associations between severe periodontitis and several NCDs, in particular CVD. In 2012 a joint workshop was held between the European Federation of Periodontology (EFP) and the American Academy of Periodontology to review the literature relating periodontitis and systemic diseases, including CVD. In the last five years important new scientific information has emerged providing important emerging evidence to support these associations. Results and Conclusions: The present review reports the proceedings of the workshop jointly organised by the EFP and the World Heart Federation (WHF), which has updated the existing epidemiological evidence for significant associations between periodontitis and CVD, the mechanistic links and the impact of periodontal therapy on cardiovascular and surrogate outcomes. This review has also focused on the potential risk and complications of periodontal therapy in patients on anti thrombotic therapy and has made recommendations for dentists, physicians and for patients visiting both the dental and medical practices.

Masticatory Capacity and Mortality: The Preventive and Clinical Investigation Center (IPC) Cohort Study.

Poor oral health (OH) has been associated with mortality, but the association between OH components and mortality remains imprecise. The present observational study aimed to investigate if there is an association between oral masticatory efficiency and cardiovascular (CV) mortality in a large French subject cohort. The study was based on a cohort of 85,830 subjects aged between 16 and 94 y at recruitment. The follow-up extended from 2001 to 2014 and the mean follow-up was 8.06 ± 2.73 y. The number of deaths totaled 1,670. Full-mouth examinations were performed. Dental plaque, dental calculus, gingival inflammation, missing teeth, and masticatory units were recorded. Masticatory units represent the number of natural or prosthetic opposing premolars and molar pairs and can be considered an accurate indicator for masticatory efficiency. Causes of death were ascertained from death certificates. Cox regression analyses were used to calculate hazard ratios (HRs). In the fully adjusted model, the number of masticatory units <5 is associated with an HR of 1.72 (95% confidence interval [CI], 1.54 to 1.91) for all-cause mortality, HR of 1.41 (95% CI, 1.01 to 1.99) for CV mortality, HR of 1.76 (95% CI, 1.44 to 2.15) for cancer mortality, and HR of 1.85 (95% CI, 1.55 to 2.20) for non-CV and noncancer mortality. Significant statistical associations with the other oral variables were also found for all-cause mortality, cancer mortality, and non-CV and noncancer mortality in the adjusted models. Our study indicates that after full adjustment, all oral parameters are associated with all-cause, cancer, and non-CV and noncancer mortality. However, the low number of masticatory units is associated with an increased risk of CV mortality. We highlight the association of masticatory units and CV mortality.

Multivisceral Resection for Locally Advanced Gastric and Gastroesophageal Junction Cancers-11-Year Experience at a High-Volume North American Center.

INTRODUCTION: The oncologic benefit of multivisceral en bloc resections for T4 gastroesophageal tumors has been questioned, given the increased morbidity associated. We thus sought to investigate the surgical and oncologic outcomes of curative-intent en bloc multivisceral resections for T4 gastroesophageal carcinomas. METHODS: Between 2005 and 2016, 35 of the 525 patients who had gastric or EGJ carcinomas underwent curative-intent multivisceral resections for direct invasion or adhesion to adjacent organs. RESULTS: Postoperative complications occurred in 16(46%), 10 of which were Clavien-Dindo ≥ 3 (29%). Ninety-day mortality was 3%. The R0 resection rate was 94% (33). Direct organ invasion (pT4b) was confirmed on pathological analysis in 14 (40%) and did not affect survival. The majority (28, 80%) had lymph node involvement with a high nodal disease burden and was associated with decreased survival. Overall 5-year survival rate was 34%, and the vast majority of recurrences were distant/peritoneal (81%). On multivariate analysis, positive lymph nodes (H.R. 21.2; 95%CI 2.34-192) and R1 resection (H.R. 5.6; 95%CI 1.02-30.9) were predictors of survival. CONCLUSION: Multivisceral resections for T4 gastric and GEJ adenocarcinomas, in combination with effective systemic therapy, result in prolonged long-term survival with acceptable morbidity. Complete resection to negative margins should remain a mainstay of curative-intent treatment in carefully selected patients.

Impact on testicular function of a single ablative activity of 3.7 GBq radioactive iodine for differentiated thyroid carcinoma.

STUDY QUESTION: What are the consequences of radioactive iodine (RAI) therapy for testicular function? SUMMARY ANSWER: A single activity of 3.7 GBq RAI for differentiated thyroid carcinoma (DTC) treatment in young men transiently altered Sertoli cell function and induced sperm chromosomal abnormalities. WHAT IS KNOWN ALREADY: Few studies, mainly retrospective, have reported the potential impacts of RAI on endocrine and exocrine testicular function. STUDY DESIGN, SIZE, DURATION: A longitudinal prospective multi-center study on testicular function performed in DTC patients before a single 131I ablative activity of 3.7 GBq (V0) and at 3 months (V3) and 13 months (V13) after treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS: Forty male patients, aged 18-55 years, with DTC participated. Hormonal analysis included FSH, LH, testosterone and inhibin B serum levels at V0, V3 and V13. Furthermore, sperm parameters, DNA fragmentation and sperm chromosomal abnormalities were evaluated at each time points. The differences in all parameters, between V0-V3, V0-V13 and V3-V13, were analyzed, using a Wilcoxon test. MAIN RESULTS AND THE ROLE OF CHANCE: Prior to RAI administration, all patients had normal gonadal function. At V3, a statistically significant increase in FSH levels and a decrease in inhibin B levels were observed and sperm concentration, as well as the percentage of morphologically normal spermatozoa, were significantly decreased (P < 0.0001). These modifications were transient as both sperm concentration and normal morphology rate returned to baseline values at V13. However, at this later time point, FSH and inhibin B levels were still impacted by RAI administration but remained in the normal range. Although no DNA fragmentation was observed at V3 nor V13, our study revealed a statistically significant increase in the number of sperm chromosomal abnormalities both at V3 (P < 0.001) and V13 (P = 0.01). LIMITATIONS, REASONS FOR CAUTION: Among the 40 patients included in the study, only 24 had all the parameters available at all visits. WIDER IMPLICATIONS OF THE FINDINGS: Prospective studies with longer term follow up would be helpful to determine whether the chromosome abnormalities persist. These studies would be required before sperm banking should be suggested for all patients. However, sperm preservation for DTC patients who require cumulative radioiodine activities higher than 3.7 GBq should be proposed. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the Programme Hospitalier de Recherche Clinique, AP-HP (No. P040419). The authors report no conflict of interest in this work. TRIAL REGISTRATION NUMBER: NCT01150318.

Selective progesterone receptor modulators: current applications and perspectives.

Selective progesterone receptor modulators (SPRMs) are steroid progesterone receptor ligands able to induce agonistic or antagonistic activities. Mifepristone, the class leader, was primarily used for pregnancy termination from the 1980s. Emergency contraception with extended activity was the second major development 30 years later, with mifepristone in some countries and ulipristal acetate world-wide. More recently, ulipristal acetate was released for the treatment of myoma-related uterine bleeding. In addition to a very rapid cessation of bleeding, SPRMs allow a decrease in myoma volume, as do gonadotropin releasing hormone analogs. However, estradiol secretion is not blunted by SPRMs. This offers new alternatives for myoma treatment, especially in women close to menopause. In conclusion, use of SPRMs has allowed significant progress in emergency contraception and treatment of myoma-related symptoms. Numerous future perspectives in women's health care are currently under evaluation.

Differences between inflammatory and catabolic mediators of peri-implantitis and periodontitis lesions following initial mechanical therapy: An exploratory study.

BACKGROUND AND OBJECTIVE: The aim of this study was to analyze the differences in inflammatory and catabolic mediators expressed in peri-implantitis compared to periodontitis lesions after non-surgical therapy. Peri-implantitis is associated with a faster rate of bone loss when compared with periodontitis, and peri-implant non-surgical therapy is ineffective to cure peri-implantitis. This may be due to persistent inflammation in peri-implantitis tissues after initial mechanical treatment. MATERIAL AND METHODS: Eleven patients with peri-implantitis and 10 with severe chronic periodontitis received non-surgical therapy. They were included at re-evaluation (8 weeks) if they presented pocket depth ≥6 mm with bleeding on probing, and the indication for open flap debridement surgery. Connective tissues were harvested during surgery from diseased sites. Healthy gingiva were harvested during third molar extraction in a third group of healthy patients (n=10). Explants were incubated for 24 hours in media culture and the release of cytokines, chemokines, growth factors, osteoprotegerin, receptor activator of nuclear factor kappa-B ligand (RANKL), matrix metalloproteinase and tissue inhibitors of matrix metalloproteinase (TIMP) in the conditioned media was analyzed by an exploratory multiplex immunoassay. When difference was found in the conditioned media, an immunohistochemistry was performed to compare expression in the tissues. RESULTS: Connective tissues from non-stabilized peri-implantitis exhibited a distinct cytokine profile compared to periodontitis lesions that did not respond to initial therapy. Indeed, TIMP-2 was significantly increased in media from peri-implantitis (P≤.05). In addition, the in situ expression of TIMP-2, interleukin-10 and RANKL was also significantly increased in peri-implantitis tissues (P≤.05). However, the ratio of RANKL/osteoprotegerin-positive cells did not vary (P≥.05). CONCLUSION: This study suggests that peri-implantitis and periodontitis connective tissues exhibit differences in response to non-surgical treatment, which may contribute to a different pattern of disease evolution.

Fate and ecotoxicological impact of new generation herbicides from the triketone family: An overview to assess the environmental risks.

Triketones, derived chemically from a natural phytotoxin (leptospermone), are a good example of allelochemicals as lead molecules for the development of new herbicides. Targeting a new and key enzyme involved in carotenoid biosynthesis, these latest-generation herbicides (sulcotrione, mesotrione and tembotrione) were designed to be eco-friendly and commercialized fifteen-twenty years ago. The mechanisms controlling their fate in different ecological niches as well as their toxicity and impact on different organisms or ecosystems are still under investigation. This review combines an overview of the results published in the literature on ß-triketones and more specifically, on the commercially-available herbicides and includes new results obtained in our interdisciplinary study aiming to understand all the processes involved (i) in their transfer from the soil to the connected aquatic compartments, (ii) in their transformation by photochemical and biological mechanisms but also to evaluate (iii) the impacts of the parent molecules and their transformation products on various target and non-target organisms (aquatic microorganisms, plants, soil microbial communities). Analysis of all the data on the fate and impact of these molecules, used pure, as formulation or in cocktails, give an overall guide for the assessment of their environmental risks.

Periodontopathogens antibodies and major adverse events following an acute myocardial infarction: results from the French Registry of Acute ST-Elevation and Non-ST-Elevation Myocardial Infarction (FAST-MI).

BACKGROUND: Periodontopathogens antibodies have been shown to be associated with primary myocardial events, but little is known regarding their impact on major adverse events after a prior acute myocardial infarction (AMI). The present prospective study evaluates the association between antibody levels of 4 periodontopathogens and the risk of all-cause death or non-fatal myocardial infarction (MI) at 1 year in 975 patients admitted for acute ST segment or non-ST segment elevation MI in French Registry of Acute ST-Elevation and Non-ST-Elevation Myocardial Infarction (FAST-MI), a nationwide French survey. METHODS: Multiserotype ELISAs were performed to assess levels of IgG and IgA against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Prevotella intermedia and Tannerella forsythia. RESULTS: Adjusted HRs indicate the lack of association between IgG-anti-Po. gingivalis levels (0.96 (0.78 to 1.18)), IgA-anti-Po. gingivalis levels (1.13 (0.90 to 1.42)) and the risk of all-cause death or non-fatal MI at 1 year. Additionally, no significant association was found between the occurence of an event at 1 year and immunoglobulins levels against the others periodontopathogens. CONCLUSIONS: The present data indicate that circulating levels of periodontopathogens antibodies are not associated with an increased risk of major adverse events in patients with a prior AMI. Studies dealing with bacterial and clinical data are needed to assess the role of oral health in comprehensive cardiac rehabilitation programmes.

Determination and mitigation of the uncertainty of neutron diffraction measurements of residual strain in large-grained polycrystalline material.

For large-grained samples it is advantageous to perform pairs of neutron diffraction measurements at the same spatial location but rotated 180° around the geometric centre of the gauge volume as a means of minimizing the scatter coming from the random positioning of grains within the gauge volume.

New lithium metal polymer solid state battery for an ultrahigh energy: nano C-LiFePO4 versus nano Li1.2V3O8.

Novel lithium metal polymer solid state batteries with nano C-LiFePO4 and nano Li1.2V3O8 counter-electrodes (average particle size 200 nm) were studied for the first time by in situ SEM and impedance during cycling. The kinetics of Li-motion during cycling is analyzed self-consistently together with the electrochemical properties. We show that the cycling life of the nano Li1.2V3O8 is limited by the dissolution of the vanadium in the electrolyte, which explains the choice of nano C-LiFePO4 (1300 cycles at 100% DOD): with this olivine, no dissolution is observed. In combination with lithium metal, at high loading and with a stable SEI an ultrahigh energy density battery was thus newly developed in our laboratory.

A pre-clinical murine model of oral implant osseointegration.

Many of our assumptions concerning oral implant osseointegration are extrapolated from experimental models studying skeletal tissue repair in long bones. This disconnect between clinical practice and experimental research hampers our understanding of bone formation around oral implants and how this process can be improved. We postulated that oral implant osseointegration would be fundamentally equivalent to implant osseointegration elsewhere in the body. Mice underwent implant placement in the edentulous ridge anterior to the first molar and peri-implant tissues were evaluated at various timepoints after surgery. Our hypothesis was disproven; oral implant osseointegration is substantially different from osseointegration in long bones. For example, in the maxilla peri-implant pre-osteoblasts are derived from cranial neural crest whereas in the tibia peri-implant osteoblasts are derived from mesoderm. In the maxilla, new osteoid arises from periostea of the maxillary bone but in the tibia the new osteoid arises from the marrow space. Cellular and molecular analyses indicate that osteoblast activity and mineralization proceeds from the surfaces of the native bone and osteoclastic activity is responsible for extensive remodeling of the new peri-implant bone. In addition to histologic features of implant osseointegration, molecular and cellular assays conducted in a murine model provide new insights into the sequelae of implant placement and the process by which bone is generated around implants.

Prevalence of tooth wear on buccal and lingual surfaces and possible risk factors in young European adults.

To assess the prevalence of tooth wear on buccal/facial and lingual/palatal tooth surfaces and identify related risk factors in a sample of young European adults, aged 18-35 years. Calibrated and trained examiners measured tooth wear, using the basic erosive wear examination (BEWE) on in 3187 patients in seven European countries and assessed the impact of risk factors with a previously validated questionnaire. Each individual was characterized by the highest BEWE score recorded for any scoreable surface. Bivariate analyses examined the proportion of participants who scored 2 or 3 in relation to a range of demographic, dietary and oral care variables. The highest tooth wear BEWE score was 0 for 1368 patients (42.9%), 1 for 883 (27.7%), 2 for 831 (26.1%) and 3 for 105 (3.3%). There were large differences between different countries with the highest levels of tooth wear observed in the UK. Important risk factors for tooth wear included heartburn or acid reflux, repeated vomiting, residence in rural areas, electric tooth brushing and snoring. We found no evidence that waiting after breakfast before tooth brushing has any effect on the degree of tooth wear (p=0.088). Fresh fruit and juice intake was positively associated with tooth wear. In this adult sample 29% had signs of tooth wear making it a common presenting feature in European adults.

Comparison of stress distribution in the temporomandibular joint during jaw closing before and after symphyseal distraction: a finite element study.

The aim of this study was to predict stress modification in the temporomandibular joint (TMJ) after symphyseal distraction (SD). The study was performed using three-dimensional finite element analysis using a complete mastication model. Geometric data were obtained from MRI and CT scans of a healthy male patient and each component was meshed as various regions. The distraction was performed with a 10mm expansion after simulation of a surgical vertical osteotomy line on the model in the mandibular midline region. The geometry and mesh of the bone callus were constructed. The bone callus was modelled as a strengthened region characterized by a Young's modulus corresponding to consolidated bone to predict the long-term biomechanical effect of SD. Boundary conditions for jaw closing simulations were represented by different jaw muscle load directions. The von Mises stress distributions in both joint discs and condyles during closing conditions were analysed and compared before and after SD. Stress distribution was similar in discs and on condylar surfaces in the pre- and post-distraction models. The outcomes of this study suggest that anatomical changes in TMJ structures should not predispose to long-term tissue fatigue and demonstrate the absence of clinical permanent TMJ symptoms after SD.

[Revision of of the subfamily of Metaracoelophryinae de Puytorac 1972 (Oligohymenophora: Hoplytophryida: Hoplytophryidae), astome ciliates of the digestive tract of Oligochaeta worms of Africa: description of five new species]. / Révision de la sous-famille des Metaracoelophryinae de Puytorac 1972 (Oligohymenophora : Hoplytophryida : Hoplytophryidae), ciliés astomes du tube digestif d'oligochètes terricoles d'Afrique : description de cinq espèces nouvelles.

Five new species belonging to the astome ciliates, living in the digestive tract of Oligochaeta worms belonging to the genus Alma from Cameroon, have been described. The techniques used are: vital staining, staining of the nucleus with Diamidino Phenyl Indol (DAPI), scanning electron microscopy and silver staining method (Fernandez Galiano, 1976, 1994). This work confirms the presence of the genus Paracoelophrya and Dicoelophrya in the digestive track of the oligochaete Alma from Gabon and Cameroon; it helps to understand the general taxonomy of this Metaracoelophryinae subfamily. Moreover, the homogeneity of this group is confirmed and the phylogenetic relationship inside the Hoplitophryida order need more studies to be solved.

The Eigenfactor™ Score in highly specific medical fields: the dental model.

We sought to compare the Eigenfactor Score™ journal rank with the journal Impact Factor over five years, and to identify variables that may influence the ranking differences between the two metrics. Datasets were retrieved from the Thomson Reuters(®) and Eigenfactor Score™ Web sites. Dentistry was identified as the most specific medical specialty. Variables were retrieved from the selected journals to be included in a regression linear model. Among the 46 dental journals included in the analysis, striking variations in ranks were observed according to the metric used. The Bland-Altman plot showed a poor agreement between the metrics. The multivariate analysis indicates that the number of original research articles, the number of reviews, the self-citations, and the citing time may explain the differences between ranks. The Eigenfactor Score™ seems to better capture the prestige of a journal than the Impact Factor. In medicine, the bibliometric indicators should focus not only on the overall medical field but also on specialized disciplinary fields. Distinct measures are needed to better describe the scientific impact of specialized medical publications.

Randomized placebo- and active-controlled study of desvenlafaxine for menopausal vasomotor symptoms.

OBJECTIVE: To evaluate the efficacy and safety of desvenlafaxine (administered as desvenlafaxine succinate) vs. tibolone and placebo for menopausal vasomotor symptoms and the incidence of uterine bleeding. METHODS: This 12-week, double-blind, randomized, controlled trial was conducted at 35 sites in Europe, two sites in South Africa, and one site in Mexico. Postmenopausal women with ≥50 moderate or severe hot flushes per week (n = 485) were randomized to desvenlafaxine 100 mg/day, tibolone 2.5 mg/day, or placebo. Reduction in the average daily number of moderate and severe hot flushes at weeks 4 and 12 (primary endpoint) was evaluated using analysis of covariance. Safety assessments included incidence of uterine bleeding, adverse events, laboratory values, and vital signs. RESULTS: At week 12, no statistically significant difference was observed in reduction of the average daily number of moderate and severe hot flushes for desvenlafaxine (-5.78) vs. placebo (-5.82; p = 0.921), although time to 50% reduction was significantly less than placebo (13 vs. 26 days, p = 0.006). Hot flush reduction with tibolone (-8.21) was significantly greater than placebo (p < 0.001). Nausea was the most common adverse event with desvenlafaxine, was generally mild to moderate, and resolved within the first 2 weeks. Significantly more subjects experienced bleeding with tibolone (23%) vs. desvenlafaxine (12%; p < 0.024) or placebo (9%; p < 0.001). CONCLUSIONS: Desvenlafaxine did not separate from placebo in reducing the number of moderate to severe hot flushes at week 12, although it did allow women to achieve 50% reduction sooner than placebo. Tibolone did separate from placebo, but with smaller than expected effect. The placebo effect was high (57%). Adverse drug reactions were consistent with the known safety profile of desvenlafaxine, and significantly more women who received tibolone experienced episodes of bleeding compared with women who received desvenlafaxine or placebo.

Contemporary genetic technologies and female reproduction.

BACKGROUND: The Fifth Evian Annual Reproduction (EVAR) Workshop Meeting discussed knowledge regarding contemporary genetics in female reproduction. METHODS: Specialist reproductive medicine clinicians and geneticists delivered presentations based on published literature and current research. The content of this report is based on the expert presentations and subsequent group discussions that took place during this Workshop. RESULTS: Numerous ovarian genes with a role in infertility have been identified. Future challenges for genetic screening of patients, such as those with polycystic ovary syndrome, primary ovarian insufficiency or endometriosis, include the identification of high-throughput strategies and how to apply these findings to infertile patients. The identification of high-quality embryos in IVF using objective technologies remains a high priority in order to facilitate single-embryo transfer. Gene expression profiling of cumulus cells surrounding the oocyte, and proteomic and metabolomic approaches in embryo culture media may significantly improve non-invasive embryo quality assessment. CONCLUSIONS: The way forward in advancing the knowledge of genes involved in reproduction was considered to be through genome-wide association studies involving large numbers of patients. Establishing international collaboration is required to enable the application of such technologies in sufficient numbers of patients.
