It has an agestandardized incidence of 21.5/100,000. The purpose of this study was to examine the knowledge and perceived factors associated with CC screening among women from low medium income status in Bogotá, Colombia. Methodology: the study was conducted with 10 focus groups segmented by age groups (18-33, 34-49, and 50-66). Two researchers conducted content analysis and identified the emerging categories. Results: the sample consisted of 81 women whose ages ranged from 18 to 66. Early onset of sexual activity, promiscuity, vaginal infections, hpv, genetics, abortions, and lack of hygiene were identified as the most important risk factors for cc. Participants recognized that this disease does not always have symptoms, and that pap smears detect it early. However, they mentioned fear of undergoing a pap test, discomfort or pain, embarrassment, poor services, procrastination, and fear of a cancer diagnosis as the main barriers preventing regular screening. Women recommended educational campaigns and improved customer service as strategies to motivate them. Conclusion: participants reported basic knowledge about CC and screening. Actions to facilitate screening must be multifaceted and based on the barriers and facilitators mentioned by each age group.

However, current gene prediction methods can only efficiently find genes that share features such as sequence similarity or general sequence characteristics with previously known genes. Novel sequencing methods and tiling arrays can be used to find genes without prior information and they have demonstrated that novel genes can still be found from extensively studied model organisms. Unfortunately, these methods are expensive and thus are not easily applicable, e.g., to finding genes that are expressed only in very specific conditions. We demonstrate a method for finding novel genes with sparse arrays, applying it on the 33.9 Mb genome of the filamentous fungus Trichoderma reesei. Our computational method does not require normalisations between arrays and it takes into account the multiple-testing problem typical for analysis of microarray data. In contrast to tiling arrays, that use overlapping probes, only one 25mer microarray oligonucleotide probe was used for every 100 b. Thus, only relatively little space on a microarray slide was required to cover the intergenic regions of a genome. The analysis was done as a by-product of a conventional microarray experiment with no additional costs. We found at least 23 good candidates for novel transcripts that could code for proteins and all of which were expressed at high levels. Candidate genes were found to neighbour ire1 and cre1 and many other regulatory genes. Our simple, low-cost method can easily be applied to finding novel species-specific genes without prior knowledge of their sequence properties.

GPs are the first prescribers, especially for older patients. To analyse discrepancies between GPs' opinions and practice when prescribing psychotropic drugs to older patients. Postal surveys sent to GPs all over mainland France. Cross-sectional postal study. A questionnaire collected data on characteristics of GPs' practices, their opinions about psychotropic drug consumption in older people, and a full description of their last older patient receiving a psychotropic drug and seen last by the GP on that particular day. A total of 350 participating GPs saw 2498 patients aged > or =65 years. Among these patients, the prevalence of psychotropic use was 32.1% (803/2498) for anxiolytics/hypnotics, and 17.5% for antidepressants (438/2498). A total of 91% of GPs agreed that it was possible to reduce or stop psychotropic drugs for these patients. Characteristics of 339 patients taking psychotropic drug were reported: 85.8% (291/339) received at least one anxiolytic/hypnotic and 56.9% (193/339) received at least one antidepressant; there were prescribed for more than 1 year in 68.4% (199/291) and 43.5% (84/193) of the cases respectively. GPs stated that it was possible to reduce or stop anxiolytic/hypnotic drugs for only 27% (79/291) of these patients. Barriers to doing this were patients' refusal (79%), and the absence of any local offer of psychotherapy (73%) or alternative therapy (70%). A mismatch exists between GPs' intent (91%) and practice (27%) regarding reduction of psychotropic prescription in individuals aged > or =65 years. The barriers encountered should be examined further to help physicians improve management of psychotropic prescription.

General Practitioners (GPs) play a central role in suicide prevention. However data about how physicians deal with suicidal youths are lacking. This study aims to compare young adult suicide attempters (from 18 to 39 years old) with older adults in a primary care setting. Methods: A cross-sectional study was carried. All suicide attempts (N=270) reported to the French Sentinel surveillance System from 2009 to 2011 were considered. We conducted comparison of data on the last GP's consultation and GPs' management in the last three months between young adults and older adults. Results: In comparison with older adults, young adults consulted their GP less frequently in the month preceding the suicidal attempt (40.9 vs. 64.6%, p=.01). During the last consultation prior to the suicidal attempt, they expressed suicidal ideas less frequently (11.3 vs. 21.9%, p=.03). In the year preceding the suicidal attempt, GPs identified depression significantly less often (42.0 vs. 63.4%, p=.001). In the preceding three months, GPs realized significantly less interventions: less psychological support (37.5 vs. 53.0%, p=.02), prescribed less antidepressants (28.6 vs. 54.8%, p<.0001) or psychotropic drugs (39.1 vs. 52.9%, p=.03) and made fewer attempts to refer to a mental health specialist (33.3 vs. 45.5%, p=.05). Conclusion: With young adults who subsequently attempt suicide, GPs face particular difficulties compared to older adults, as a significant proportion of young adults were not seen in the previous six months, as GPs identified less depressions in the preceding year and were less active in managing in the preceding three months. Medical training and continuing medical education should include better instruction on challenges relative to addressing suicide risk in this particular population.

However little is known about how parents from these regions behave when they migrate to countries that have different cultural norms. It is therefore important to determine how ethno-cultural background affects parental behavior and subsequent child mental health in the context of immigration. The objectives are: 1) to compare negative parenting behaviors of French residents from diverse ethno-cultural backgrounds 2) to examine the relationship between parental region of origin and child mental health, and 3) to investigate the extent to which ethno-cultural context moderates the effect of parenting styles on child mental health. A cross-sectional study was conducted in 2005 in 100 schools in South-East France. The Dominic Interactive and the parent-reported Strengths and Difficulties Questionnaire were used to assess child psychopathology. The Parent Behavior and Attitude Questionnaire was used to assess parenting styles. The final sample included data on 1,106 mother and child dyads. Caring and punitive attitudes were significantly different across mothers as a function of region of origin. This association was stronger for punitive attitudes with the highest prevalence in the Caribbean/African group, while mothers from Maghreb were more similar to French natives. Differences in caring behaviors were similar though less pronounced. Among children of Maghrebian descent, punitive parenting was associated with an increased risk of internalizing disorders while this association was weaker among children of African and Afro-Caribbean descent. Parental region of origin is an important component of both parenting styles and their effect on child mental health. Interventions on parenting should consider both the region of origin and the differential impact of origin on the effect of parenting styles, thus allowing for a finer-grained focus on high-risk groups.

This study aims to compare the characteristics of individuals who attempt suicide to those who complete suicide in a same primary care setting. We compared the characteristics and GP&amp;amp;amp;amp;amp;amp;#39;s management of all patients with attempted (N=498, SA) or completed suicide (N=141, SC) reported to the GPs&amp;amp;amp;amp;amp;amp;#39;French Sentinelles surveillance system (2009-2013). Compared to patients who attempted suicide, those who completed suicide were more likely to be male, older and to have used a more lethal method; for men they were less likely to have a history of previous suicide attempt and prior contacts with their GP. In terms of GPs&amp;amp;amp;amp;amp;amp;#39; management, we found no differences between the SA and SC groups in the identification of psychological difficulties and in the care, but GPs were more likely to provide psychological support to the SA group. During the last consultation, the SC group expressed suicidal ideas more frequently than the SA group (26.7% vs. 14.8%, p&amp;amp;amp;amp;amp;amp;lt;0.01), only for women. The network may have missed cases and selected more serious SA. Individuals who commit suicide differ from those who attempt suicide in terms of demographic characteristics and by sex, of history of suicide attempt, previous contact and expressed suicidal ideas. We show that GPs do not act more intensively with patients who will commit suicide, as if they do not foresee them. Current prevention programs particularly in primary care should be tailored.

Surveillance involves repeated data collections based on epidemiological studies and follow-up of data collected from medical-administrative databases. This paper provides an overview of mental health surveillance in France and examines the relevance and limitations of the collected data. The prevalence of major depressive episodes (MDE) in the general population was recently examined in seven studies. Among these studies, the Health Barometers involved two data collections at a five-year interval using the same method. Mortality and hospitalization data are important for suicide and suicide attempt (SA) surveillance. Health insurance databases provide key information about psychotropic drug use and serious psychiatric illnesses defined as long-term. The prevalence of 12‑month MDE remained stable at 7.8% between 2005 and 2010. Mortality data show a suicide rate of 16 per 100,000 inhab...

The aims of this study were to estimate the 12-month prevalence rates of depressive disorders among ninth grade pupils in French schools, and to identify the sociodemographic correlates. The data were collected through a national cross-sectional study conducted among ninth grade pupils in France in 2003-2004. Depressive disorders were assessed using a self-administered questionnaire derived from the standardised Composite International Diagnosis Interview-Short Form (CIDI-SF). A total of 7110 teenagers (mean age 15.1 years) were included. Of these, 9.6% (95% CI 8.6-10.6) reported symptoms corresponding to at least one major depressive episode (MDE) over the past 12 months. Three correlates were independently associated with a higher prevalence of 12-month MDE: being a female (adjusted odds ratio 3.0; 95% CI 2.4-3.8), bein...
