Abstract: Introduction: Human papillomavirus (HPV) infection is the most widespread sexually transmitted infection in the world. Today, there is growing evidence that HPV can be transmitted early in life, and one potential route is mother-to-child transmission. Data on this route of HPV transmission are scarce in Africa and particularly in Burkina Faso, where no data on the subject are yet available. The aim of our study was to estimate the rate of mother-to-child transmission of HPV infection and to identify circulating genotypes. Methodology: Cervico-uterine samples were collected from 100 full-term pregnant women and, buccal samples were obtained from their newborns at Hopital Saint Camille de Ouagadougou (HOSCO) by the specialist physician. HPV DNA amplification and genotyping were performed by PCR followed by hybridization using the HPV Direct Flow Chips kit, detecting 36 genotypes including 18 high-risk and 18 low-risk. Results: The prevalence of HPV in newborns was 8% (8/100). Six (6) HPV-positive neonates had HPV-positive mothers, while 2 HPV-positive neonates had HPV-negative mothers. The vertical transmission rate was 26.09% (6/23). Mother-newborn genotypes were concordant. However, the genotype profile of the newborns was more restricted than that of the mothers. Conclusion: HPV DNA was found in 8% of newborns in our study. The genotype profile of the mother-newborn pair was concordant. Asymptomatic HPV infection in a pregnant woman could constitute a risk factor for vertical transmission.

Abstract: Cervical cancer is the fourth most common cancer worldwide, accounting for 6.8% of new cancer cases and 8.1% of cancer-related deaths. About 85% of these deaths occurred in low- and middle-income countries. The aim of this study was to assess the frequency and distribution of the human papillomavirus (HPV) genotypes in women showing cytological abnormalities of the cervix at the Sour？ SANOU University Hospital (CHUSS) in Bobo-Dioulasso, Burkina Faso. This is a descriptive study of women recruited at the CHUSS. The cervico-uterine smear examination was carried out at the CHUSS Anatomy and Pathology Department for cervical cancer screening. The data were collected from women with atypical cells on their cervico-uterine smear. Cervicovaginal samples were taken from consenting women and HPV genotyping was performed using the HPV Direct FLOW CHIP kit at CERBA. We obtained approval from the ethics committee. The data were analyzed using the SPSS 26 software. The results of the study showed that 67.79% of the participants were aged between 50 and 65, a group that is particularly vulnerable to persistent infection with high-risk oncogenic HPV genotypes. Of the women screened, 40.7% were HPV positive and 29.2% had multiple infections. The most common genotypes were HPV 35, followed by HPV 18, 52, 58 and 66. These data highlight the need for increased surveillance and targeted prevention strategies among this female population.

Abstract: The spatial distribution of bats in Burkina Faso is little-known. Previous studies have only described the bat species’ richness in Burkina Faso. This study was conducted to highlight bat species’ richness distribution within Burkina Faso and environmental variables that influence this distribution with the aim to give support for protection and further sampling for biodiversity. The Species Distribution Models (SDMs) were used to perform this study. To do that, species occurrences were collected throughout literature and field sampling and correlated to environmental variables through the Maxent software (Maximum Entropy). Our modeling variables included climate, vegetation cover, topography and hydrography data. The Jackknife test was performed to determine the importance of environmental variables that influence the species distribution model. The results showed that bats are present in all areas of vegetation in Burkina Faso. Species richness varies across the country. The species richness for major families increases from North to South. The total annual precipitation and topography are the main variables that positively influence bats distribution in Burkina Faso but the bare ground cover and standard deviation of the maximum temperature negatively influence this distribution. This modeling approach of bat species richness is important for policies makers and represents an invaluable tool in ecological management, particularly in the current context of climate change.
Exploring the Differences between Hispanic Men and Women with Type 2 Diabetes Mellitus Using the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)  [PDF]

Abstract: Studies have shown Hispanic patients are at an increasing risk of developing type 2 diabetes; however, little is known about whether gender plays a role. Several studies were examined to help answer this question. Results of studies found female Hispanic patients tend to be more sedentary and thus struggle more with obesity, while male Hispanic patients tend to be more at risk due to smoking status and hypercholesterolemia. In addition, psychological distress and chronic stress were more likely to affect the risk for diabetes in men while immigration status was more likely to affect cardiovascular health in women. More studies are needed to fully understand the role of gender on diabetes risk; however, practitioners can utilize known information in order to tailor treatment to male or female Hispanic patients.
Karyotypic polymorphism and evolution within and between the Liolaemus monticola (Iguanidae) "northern 2n = 38-40" chromosome race populations in central Chile

Revista chilena de historia natural , 2001, DOI: 10.4067/S0716-078X2001000000017
Abstract: chromosomal genotypes were scored from 359 liolaemus monticola lizards of the "northern, 2n = 38-40" chromosomal race from 21 locality samples between the maipo (and one of its tributaries) and the aconcagua (and one of its tributaries) ribers, plus a sample from the interracial hybridization zone, and some representative locality samples of the "southern 2n = 34" and the "multiple fission 2n = 42-44" chromosomal races for comparisons. the first seven variable chromosomal pairs were coded as mendelian genotypes and statistically summarized by several clustering and population genetic algorithms. spatial and temporal differentiation was assessed by chromosome frequencies, chromosomal diversity and heterozygosity. while no differentiation was found for diversity in the "northern 2n = 38-40" race, chromosomal frequencies and heterozygosity showed significant spatial differentiation that permit distinguishing between the coastal, andean and transversal mountain range populations. the sample of cuesta chacabuco may represent a hybrid zone between the other two range samples. the origin of the chromosomal rearrangements, the population cytogenetics, and the recombination patterns resulting from chromosomal heterozygosity are compared in these chromosomal races, thus expanding the geographical area. these patterns are discussed with respect to the evolution of this complex in chile and the importance of the riverine barriers in central chile

Madeleine,Richer;
Revista de Ciencias Sociales , 2005,
Abstract: this article analyzes citizen participation and community organizations in the health sector in the canadian province of québec. participation is a theme of great relevance in democracy, and also in the efficiency and efficacy of public services. in the quebec health system different participation models co-exist : consultative citizen participation, assemblies and public forums, and decision making participation through representation in administrative councils in regional organizations, health installations and social services. the integration of health services and social services within its administration is an original facet of the quebec system. another distinctive characteristic is the importance of the social movement known as the quebec community movement, which has achieved important recognition and innovation in the handling of social and health problems.
La précarité au Québec : un concept parmi d’autres pour parler des jeunes

Abstract: Ce texte met en contexte l’usage du concept de précarité au Québec. Celui-ci a surtout été utilisé parmi beaucoup d’autres pour décrire la situation des jeunes au moment de la crise de l’emploi des décennies 1970 et 1980. Il a parfois contribué, par son attribution à l’ensemble des jeunes, à laisser les plus vulnérables dans l’ombre et à amplifier l’effet du travail atypique sur l’avenir de toute une génération. Un usage plus modéré du concept s’est imposé progressivement en présence de faits plus justement vérifiés. Sa force de persuasion a pu susciter des stratégies tant individuelles que collectives en faveur des jeunes. Ce retour dans le temps a permis de montrer que les jeunes sont sensibles à la conjoncture mais n’en restent pas pour autant les victimes. Est-ce à cause du type d’état (de G sta Esping-Anderson, évoqué par Mircea Vultur) que le concept n’a eu qu’une importance relative au Québec ? La question se pose-t-elle dans une approche pragmatique du changement ? "Precariousness" in Québec: one of several concepts applied to young peopleThis paper examines the concept of "precariousness" in a Québec context. This concept was one of several used to describe the situation of young people during the employment crisis of the 1970s and 1980s. It was applied to young people as a whole and thus sometimes favoured a tendency to gloss over the highly vulnerable situations and to amplify the effect of non-standard employment on the future of an entire generation. More moderate use of the concept gradually prevailed with more accurate data. It was a persuasive concept that did bring about individual and collective strategies to help young people. This look backward in time shows that young people are sensitive to the economy and its performance. They are nonetheless not permanently victims of economic downturn. Is the type of welfare state (Esping-Anderson as argued by Vultur) the reason why the concept has had only relative importance in Québec? Should the question be raised as part of a pragmatic approach to change? La Precariedad en Québec: un concepto entre otros para hablar de la JuventudEste texto contextualiza la utilización del concepto de precariedad en Québec. El concepto se ha utilizado, entre otros muchos, para describir la situación de los jóvenes en el momento de la crisis del empleo de los a os 1970-1980. Por habérsele atribuido a la totalidad de los jóvenes, a veces contribuyó a dejar en la oscuridad a aquéllos más vulnerables y a amplificar los efectos del trabajo atípico sobre el futuro de una generación entera. Paulatinamente, se ha i

Abstract: Chromosomal genotypes were scored from 359 Liolaemus monticola lizards of the "northern, 2n = 38-40" chromosomal race from 21 locality samples between the Maipo (and one of its tributaries) and the Aconcagua (and one of its tributaries) ribers, plus a sample from the interracial hybridization zone, and some representative locality samples of the "southern 2n = 34" and the "multiple fission 2n = 42-44" chromosomal races for comparisons. The first seven variable chromosomal pairs were coded as Mendelian genotypes and statistically summarized by several clustering and population genetic algorithms. Spatial and temporal differentiation was assessed by chromosome frequencies, chromosomal diversity and heterozygosity. While no differentiation was found for diversity in the "northern 2n = 38-40" race, chromosomal frequencies and heterozygosity showed significant spatial differentiation that permit distinguishing between the coastal, Andean and transversal mountain range populations. The sample of Cuesta Chacabuco may represent a hybrid zone between the other two range samples. The origin of the chromosomal rearrangements, the population cytogenetics, and the recombination patterns resulting from chromosomal heterozygosity are compared in these chromosomal races, thus expanding the geographical area. These patterns are discussed with respect to the evolution of this complex in Chile and the importance of the riverine barriers in central Chile Se cuantificaron los "genotipos" cromosómicos para 359 lagartijas de 21 muestras poblacionales de la raza "Norte, 2n = 38-40" comprendida entre los ríos: río Maipo y uno de sus afluentes el río Yeso y río Aconcagua (y uno de sus afluentes el río Juncal). Con fines comparativos agregamos una muestra de la zona de hibridación interracial, algunas muestras representativas de la raza "Sur 2n = 34" y una de la raza "múltiples fisiones 2n = 42-44". Los siete primeros pares cromosómicos variables fueron codificados como genotipos mendelianos y resumidos en varios algoritmos de agrupaciones y de genética de poblaciones. La diferenciación espacial y temporal fue pesquisada por las frecuencias cromosómicas, la diversidad cromosómica y la heterocigocidad. Si bien en la raza "Norte 2n = 38-40" no encontramos diferenciación para la diversidad cromosómica, las frecuencias y la heterocigosidad cromosómicas muestran una significativa diferenciación espacial, permite distinguir las poblaciones procedentes de la cordillera de La Costa, cordillera de Los Andes y cordón transversal. La muestra Cuesta de Chacabuco (Transversal) podría correspo
