Seasonal gonadal development and age-related maturity patterns of introduced pumpkinseed (Lepomis gibbosus Linnaeus, 1758) in a heated thermal reservoir and an adjacent river reach. J Therm Biol 2016; 58:60-71.

Abstract
Testis and ovarian maturation status, maturity profile and gonado-somatic index (GSI) were assessed in pumpkinseed (Lepomis gibbosus) collected from Mirgenbach, a cooling-water reservoir associated with a nuclear power plant, and from the River Moselle 7km downstream of the reservoir's thermal outflow. Histological investigation indicated that in both sexes, gonadal development of pumpkinseed in the heated reservoir was more advanced than in the cooler Moselle River throughout the breeding season. The histological maturity profile of reservoir males ranked by the advancement of sperm cells was highly correlated with its GSI (rs=0.73, P<0.001). GSI of females in the reservoir increased with the stage at maturity, but GSI was not significantly correlated with total length, age or growth rate of the individual. All sampled individuals of both sexes were mature at age 1 in the heated reservoir, whereas 48% of age 1 males and 57% of age 1 females were not mature in the river. GSI patterns suggest that males in the reservoir adopted one of two reproductive strategies (nesters or cuckolders), whereas no small males with large enough testes to be considered cuckolders were apparent in the river. The warm thermal regime of Mirgenbach Reservoir led to precocial maturity, early season reproduction, and the greater prevalence of apparent cuckolder males than would normally occur in this climatic zone.

Abstract
Using Icelandic whole-genome sequence data and an imputation approach we searched for rare sequence variants in CHRNA4 and tested them for association with nicotine dependence. We show that carriers of a rare missense variant (allele frequency=0.24%) within CHRNA4, encoding an R336C substitution, have greater risk of nicotine addiction than non-carriers as assessed by the Fagerstrom Test for Nicotine Dependence (P=1.2 × 10(-4)). The variant also confers risk of several serious smoking-related diseases previously shown to be associated with the D398N substitution in CHRNA5. We observed odds ratios (ORs) of 1.7-2.3 for lung cancer (LC; P=4.0 × 10(-4)), chronic obstructive pulmonary disease (COPD; P=9.3 × 10(-4)), peripheral artery disease (PAD; P=0.090) and abdominal aortic aneurysms (AAAs; P=0.12), and the variant associates strongly with the early-onset forms of LC (OR=4.49, P=2.2 × 10(-4)), COPD (OR=3.22, P=2.9 × 10(-4)), PAD (OR=3.47, P=9.2 × 10(-3)) and AAA (OR=6.44, P=6.3 × 10(-3)). Joint analysis of the four smoking-related diseases reveals significant association (P=6.8 × 10(-5)), particularly for early-onset cases (P=2.1 × 10(-7)). Our results are in agreement with functional studies showing that the human α4β2 isoform of the channel containing R336C has less sensitivity for its agonists than the wild-type form following nicotine incubation.

Abstract
Expansion of aquaculture has increased concern over its environmental impact. The composition of effluents from intensive aquaculture is well documented, but few data on extensive aquaculture are available. During 12 draining operations, 523 water samples were collected downstream from six extensively-managed fishponds in northeastern France. Study ponds had surface areas of 2-620 ha and were managed for production of Cyprinids and Percids. Concentrations of total suspended solids, total phosphorus, and Kjeldahl nitrogen in effluents from the ponds were greatest during the final stage of draining. Loads of phosphorus were higher than those reported for effluents of more intensive aquaculture ponds in the USA, but the source of the potential pollutants was catchments and sediment rather than feeds and fertilizer. It will be necessary to reduce the water drawdown rate during the fishing stage and possibly implement other best management practices to prevent the TSS concentration from exceeding 1 g/L.

Abstract
BACKGROUND Germline CDKN2A mutations have been observed in 20-40% of high risk, melanoma prone families; however, little is known about their prevalence in population based series of melanoma cases and controls. METHODS We resequenced the CDKN2A gene, including the p14ARF variant and promoter regions, in approximately 703 registry ascertained melanoma cases and 691 population based controls from Iceland, a country in which the incidence of melanoma has increased rapidly. RESULTS We identified a novel germline variant, G89D, that was strongly associated with increased melanoma risk and appeared to be an Icelandic founder mutation. The G89D variant was present in about 2% of Icelandic invasive cutaneous malignant melanoma cases. Relatives of affected G89D carriers were at significantly increased risk of melanoma, head and neck cancers, and pancreatic carcinoma compared to relatives of other melanoma patients. Nineteen other germline variants were identified, but none conferred an unequivocal risk of melanoma. CONCLUSIONS This population based study of Icelandic melanoma cases and controls showed a frequency of disease related CDKN2A mutant alleles ranging from 0.7% to 1.0%, thus expanding our knowledge about the frequency of CDKN2A mutations in different populations. In contrast to North America and Australia where a broad spectrum of mutations was observed at a similar frequency, in Iceland, functional CDKN2A mutations consist of only one or two different variants. Additional genetic and/or environmental factors are likely critical for explaining the high incidence rates for melanoma in Iceland. This study adds to the geographic regions for which population based estimates of CDKN2A mutation frequencies are available.

Abstract
OBJECTIVES The objective of this review was to assess the efficacy of episiotomy to prevent severe perineal tears, urinary incontinence, faecal incontinence and genital prolapse. MATERIAL AND METHODS A systematic review on Medline database was performed between 1980 and 2005. One hundred seventy seven articles were selected. Trial quality was assessed on the following parameters: design (prospective, randomized, meta-analysis), sample size (>50) and relevant results. Finally, 43 articles were analysed. RESULTS The routine use of episiotomy did not prevent severe perineal tears. It decreased the risk of moderate anterior perineal lacerations. The risk of severe perineal tears during episiotomy increased in the following circumstances: primiparity, Asian women, perineal length<or=3cm, forceps or vacuum-assisted deliveries and macrosomia. Relevant studies were consistent in demonstrating no benefit for routine episiotomy to prevent urinary or faecal incontinence or pelvic floor relaxation, even if there is a lack of data concerning long-term effects on pelvic floor support. CONCLUSION The routine use of episiotomy to prevent severe perineal tears, urinary incontinence, faecal incontinence and genital prolapse should be abandoned.

Abstract
BACKGROUND For twenty years, most of industrial countries developed recommendations on regionalization of perinatal care. Perinatal regionalization is particularly aimed at improving morbidity and mortality outcomes of low birth weight newborns by transferring pregnant women to the maternity units having a medical or neonatal environment suited to the risks incurred by mothers or babies. Perinatal regionalization cannot be effective without being well accepted by the majority of professionals. The objectives of this study were then to identify professionals'expectations and objections to perinatal regionalisation and to compare them from a professional group to another one. METHODS Professionals of 3 French perinatal networks were under consideration: the Rhône, the Auvergne and the Gard-Lozère networks. The study included two stages: 1) a psychosociological qualitative study, based on professionals'interviews, aimed at identifying main concerns of professionals and developing a questionnaire; then 2) an epidemiological quantitative study, using this questionnaire within French networks. In the questionnaire, 8 dimensions explored the professionals'views: constraints related to regulation aspects and to the setting up of maternity units care levels, risk of loss of professionals' competence and prestige, consequences on medical practices, on inter-professional relationship, on work organization and financial aspects, and related to the new role of 'private practice'professionals, legal consequences. RESULTS The response rate of the epidemiological study was 80%. The results permitted to construct 8 dimension scores describing the reasons of poor acceptability of regionalization. After taking into account the age, the sex, the network and the juridical status of the institution, the study revealed a significant poorer acceptability of regionalization by most of medical specialty groups (anesthetists, obstetricians, midwives and "private practice" professionals) compared with neonatologists, or by "private" professionals (professionals working in private clinics and "private practice" professionals) compared with professionals working in university or community hospitals. The study described also network setting up conditions related to its functioning. CONCLUSION By identifying clearly professionals 'objections and expectations, this study should facilitate improvement in the organization of studied perinatal networks.

Abstract
In utero tobacco consumption is a serious public health problem in France; it is very frequent and the long term consequences are not only numerous but also misinterpreted by our population. 25 to 29% of women arrive at the end of their pregnancy without stopping smoking and 50% of non smoking mothers live in an environment polluted by tobacco during pregnancy. The authors would like to stress the gravity of this situation. At the maternity hospital in Nîmes, 358 women who gave birth at term and after a normal pregnancy were enrolled in a survey and monitored with thiocyanate for their tobacco consumption. Birth weight, height, and cranial perimeter of the infants were noted at birth. Results confirmed earlier work on this subject: the three variables studied were consistently weakened by the mother's addiction to tobacco. The authors recall previous medical literature on the pathophysiology and other consequences on the brain: such as I.Q. behavior, sudden infant death syndrome, vascular alterations with possible long-term complications, as well as pulmonary alterations on which there has recently been much research. The question is raised as to why this problem is so neglected in our society and what could be done to change this state of affairs.
