Abstract:
Introduction: The postponement of the preventive activities of the Provincial Division of Health of East Kasai 2016 revealed que le level of attendance of the preschool consultation is decreasing less and less in the Health Area Tshitenge. Thus, this study set the goal of determining the knowledge and use of maternal pre-school counseling in the Health Area Tshitenge. Methods: The survey method was used by means of a questionnary administered to mothers in this region, but more specifically, we collected data from 422 mothers responsible for randomly selected children aged 0 to 5 in the four health. Results: After analysis and analysis of the data with the computer tool, we obtained the following results: the rate of use of the preschool consultation service is 60.7%; the level of education, occupation and the number of children under 5 years of age have a strong influence on the use of preschool counseling; lack of knowledge about the most important activity of preschool counseling has a negative influence on its use. There is a link between the use of the preschool consultation and the most important activity of the preschool consultation for the respondent; there is also a link between this and an appointment on the map; and finally, the cost judgment of SPC strongly influences its use. Conclusion: In order to raise this activity, the revitalization of preschool consultation activities in the Tshitenge health area, the reinforcement of the parents’ awareness on the use of preschool counseling from 0 to 59 months, and the revival of visits to homes for children whose mothers drop out of preschool counseling sufficient are a basis.

Abstract: Objective: To assess the prevalence of prehypertension and hypertension, their determinants and associated cardiovascular risk factors in Congolese urban dwellers. Methods: From July 2007 to March 2008, we collected information on lifestyle habits, medical history and anthropometric data in 1292 household members of Adoula Quarter, Kinshasa, aged 20 years or more, 731 women (56.6%). We obtained measurements of BP, blood glucose, serum lipids and qualitative proteinuria. We defined blood pressure categories according to JNC7 classification and used logistic regression analyses to assess their independent determinants. We obtained age adjustment of continuous and categorical variables using GLM and Genmod procedures, respectively. Results: Prehypertension was observed in 30.3% of subjects, 34.9% of men and 26.7% of women (P = 0.0045). The prevalence of hypertension amounted to 30.9% with no difference between genders. Participants with prehypertension had average age, BMI and waist circumference intermediate between those with normal BP and hypertensive subjects. Their glucose and lipids levels were similar to those of normotensives. The prevalence of prehypertension amounted to 33% at age 20 - 29 years and decreased to 16.7% at ≥60 years whereas the prevalence of hypertension increased from 11.2% to 71.4%. The rates of diabetes mellitus were similar accross blood pressure catogo- ries whilst prevalences of overweight/obesity, abdominal adiposity, dyslipidemia and metabolic syndrome significatively increased (P = 0.05 or less). Among participants with prehypertension, 73% had two or more additional cardiovascular risk factors. In the logistic model the probability of prehypertension was higher in men (OR: 1.429; 95% CI: 1.099 - 1.857) and participants with overweight/obesity (OR: 1.666; 1.146 - 2.422), lower in participants aged ≥ 55 years (0.427; 0.267 - 0.683) and those with high fruit intake (0.691; 0.488 - 0.977). The probability of hypertension was higher in participants aged ≥ 55 years (OR: 6.988; 4.561 - 10.706), overweight/obesity (2.263; 1.704 - 3.004), those with high vegetables consumption (1.152; 1.003 - 1.324) and faster pulse rate (1.013; 1.002 - 1.025). Conclusion: Our results suggest that fruit consumption and control of over-weight are important issues for prevention of cardiovascular disease in sub-Saharan Africa where high blood pressure is the main driver of the current epidemic.

Potential Impact of Male Circumcision, Condom Use, and Microbicides on the Dynamics of HIV/AIDS

ISRN Biomathematics , 2012, DOI: 10.5402/2012/516519
Abstract: HIV/AIDS remains an important global cause of morbidity and mortality. While medical male circumcision and condom and microbicides use hold great promise for helping to stem the tide of new HIV infections, theoretically providing further evidence of the potential long-term population-level benefit of their combined effects is viable. A deterministic sex-structured model is formulated, the expected lifetime disease reproductive output of an individual (or epidemiological birth) is determined, and the stability of steady states is investigated. To complement HIV treatment with antiretrovirals, which is not yet fully accessible to all those in need, microbicides and nontherapeutic measures such as male circumcision and condoms provide additional potential impact on curtailing the spread of HIV/AIDS. 1. Introduction “Globally, HIV/AIDS has killed more than 25 million people, making it one of the most destructive epidemics in recorded history with sub-Saharan Africa carrying the highest burden of the disease. Since its emergence in 1981, HIV continues to be a significant social-economic and public health burden around the globe. Its main transmission route is heterosexual, representing up to 90% of all transmission.” For the estimated 33.3 million (27.1–30.3 million) people living with HIV after nearly 30 years into a very complex epidemic, the gains are real but still fragile, even as the number of annual AIDS-related deaths worldwide has steadily decreased from the peak of 2.1 million [1.9–2.3 million] in 2004 to an estimated 1.8 million [1.6–2.0 million] in 2009 [1]. Various preventative and therapeutic measures have been embarked upon, aiming at combating one of the greatest pandemic in modern times. These include the use of life-saving antiretroviral drugs (ARVs), condoms, HIV testing, mutual monogamy, counseling, and abstinence (WHO/UNAIDS, 2005) [2, 3]. Various degrees of success of these controls have been limited to very few countries [4]. Consistent use of latex condoms which is advocated as a primary prevention for HIV infection [5, 6] has suffered from problems of stigma, myths and fertility decline which are key social issues in sub-Saharan Africa [4]. Although the use of antiretroviral drugs has led to significant reduction in HIV burden in many nations, their accessibility and efficient delivery in resource-poor nations remain low. These together with the absence of an anti-HIV vaccine, call for use of other affordable programs for controlling HIV spreading especially in nations with limited resources and inadequate public health services.

Abstract:
Background: The influence of race/ethnicity on the relationship between sedentary screen time and left ventricular mass has been recently suggested, but remains a subject of debate, and has never been explored in Africa. Purpose: To determine whether there is a racial/ethnic influence on the relationship between sedentary screen time and left ventricular mass in MAGhreb and Sub Saharan Africa Left-Ventricul ArGEometry Study (MAG-SALVAGES) participants. Methods: 100 blacks sub-Saharan African and 187 white Maghreb aged 18 - 55 years underwent an interview on their behavioral measures, physical activity and eating habits. Their left ventricular mass has also been measured by a resting transthoracic echography according to the American Society of Echography. Generalized linear models evaluated a test-for-trend across higher levels of sedentary screen time in progressive models with left ventricular measurements as dependent variables. The study population was stratified into quartiles of sedentary screen time (separately for whites and blacks) and examined the joint association of sedentary screen time and LVM within quartiles of physical activity. Results: Among White Maghreb, higher screen time was associated with smaller left ventricular mass (P < 0.001). This association persisted when adjusting for age, gender, heart rate, waist circumference, waist-to-hip ratio, systolic blood pressure QRS duration, TAPS and PAPS. Whereas, in blacks sub-Saharan African, the left ventricular mass was not associated with sedentary screen time. Conclusions: Sedentary screen time is associated with smaller left ventricular mass in White Maghreb, not in black sub-Saharan African. The lack of association in blacks supports a potential qualitative difference in the cardiovascular consequences of sedentary screen based behavior.

World Journal of Cardiovascular Diseases (WJCD) , 2017, DOI: 10.4236/wjcd.2017.72005
Abstract:
There is a growing body of evidence showing a close correlation between left ventricular mass with cardiovascular morbidity and overall mortality. Therefore, identifying the determinants of left ventricular hypertrophy can be of great importance for cardiovascular prevention, for prognosis and therapeutic intervention. Objective: To assess the prevalence and identify the independent determinants of echocardiographic left ventricular hypertrophy in The MA-Ghreb and Sub-Saharan Africa Left-Ventricul ArGEometry Study (MAG-SALVAGES) participants. Methods: The MAG-SALVAGES is a community based study in which 100 asymptomatic Black Sub-Saharan African (BSSA) and 189 white skin Maghreb within the age of 18 to 55 years underwent a resting echocardiography. Multivariate logistic regression analysis was utilized to identify the independent determinants of LVH left ventricular hypertrophy. Results: Men represented the majority of the enrolled participants: 173 (59.9%). Echocardiographic left ventricular hypertrophy was seen in 10 (3.5%) participants. Age ≥40 years, female gender, overall obesity, abdominal obesity, hypertension status and less fruit consumption were significantly associated with echocardiography left ventricular hypertrophy. After adjusting for confounding factors, age ≥40 years, female gender, abdominal obesity and less fruit consumption were independently and significantly associated with echocardiographic left ventricular hypertrophy, as illustrated in the following equation: Y = 0.36 + 0.162 age >40 years + 2.69 female gender + 2.52 abdominal obesity + 1.31 less fruit consumption. Conclusion: Lifestyle changes for the prevention of abdominal obesity and encouraging fruit consumption may be beneficial in preventing left ventricular hypertrophy.

Evidence-Based Complementary and Alternative Medicine , 2011, DOI: 10.1155/2011/382789
Abstract: Introduction. Among nonantibiotic cough remedies, herbal preparations containing extracts from leaves of ivy (Hedera helix) enjoy great popularity. Objective. A systematic review to assess the effectiveness and tolerability of ivy for acute upper respiratory tract infections (URTIs). Methods. We searched for randomized controlled trials (RCTs), nonrandomized controlled clinical trials and observational studies evaluating the efficacy of ivy preparations for acute URTIs. Study quality was assessed by the Jadad score or the EPHPP tool. Results. 10 eligible studies were identified reporting on 17463 subjects. Studies were heterogeneous in design and conduct; 2 were RCTs. Three studies evaluated a combination of ivy and thyme, 7 studies investigated monopreparations of ivy. Only one RCT (=360) investigating an ivy/thyme combination used a placebo control and showed statistically significant superiority in reducing the frequency and duration of cough. All other studies lack a placebo control and show serious methodological flaws. They all conclude that ivy extracts are effective for reducing symptoms of URTI. Conclusion. Although all studies report that ivy extracts are effective to reduce symptoms of URTI, there is no convincing evidence due to serious methodological flaws and lack of placebo controls. The combination of ivy and thyme might be more effective but needs confirmation.
The importance of habitat resistance for movement decisions in the common lizard, Lacerta vivipara

BMC Ecology , 2012, DOI: 10.1186/1472-6785-12-13
Abstract: Background Movement behaviour can be influenced by a multitude of biotic and abiotic factors. Here, we investigate the speed of movement in relation to environmental and individual phenotypic properties in subadult common lizards (Lacerta vivipara). We aim to disentangle the importance of substrate, cover, humidity, basking opportunity and individual phenotype on moving tendencies in 12 treatment combinations, at which each lizard was tested. Results We find that movement behaviour depends on the starting conditions, the physical properties of the dispersal corridor, and on the individuals’ phenotype. Specifically, the presence of cover and substrate providing suitable traction in the corridor had positive effects on individual movement decisions. Additionally, we find high phenotypic variation in the propensity to move dependent on the presence of cover. Individual back patterns also strongly affected movement decisions in interaction with the physical properties of the dispersal corridor. Conclusions Our results highlight the importance of understanding the habitat resistance for movement patterns, with humid habitats with covering vegetation providing the best conditions to initiate movement in the common lizard. In addition, population effects, differences in back pattern phenotype and individual plasticity were identified as key parameters influencing movement behaviour.
Rational BV-algebra in String Topology
Yves Felix,Jean-Claude Thomas
Mathematics , 2007,
Abstract: Let $M$ be a 1-connected closed manifold and $LM$ be the space of free loops on $M$. In \cite{C-S} M. Chas and D. Sullivan defined a structure of BV-algebra on the singular homology of $LM$, $H_\ast(LM; \bk)$. When the field of coefficients is of characteristic zero, we prove that there exists a BV-algebra structure on $\hH^\ast(C^\ast (M); C^\ast (M))$ which carries the canonical structure of Gerstenhaber algebra. We construct then an isomorphism of BV-algebras between $\hH^\ast (C^\ast (M); C^\ast (M)) $ and the shifted $ H_{\ast+m} (LM; {\bk})$. We also prove that the Chas-Sullivan product and the BV-operator behave well with the Hodge decomposition of $H_\ast (LM) $.
String topology on Gorenstein spaces
Yves Felix,Jean-claude Thomas
Mathematics , 2008,
Abstract: The purpose of this paper is to describe a general and simple setting for defining $(g,p+q)$-string operations on a Poincar\'e duality space and more generally on a Gorenstein space. Gorenstein spaces include Poincar\'e duality spaces as well as classifying spaces or homotopy quotients of connected Lie groups. Our presentation implies directly the homotopy invariance of each $(g,p+q)$-string operation as well as it leads to explicit computations.
Spaces of self-equivalences and free loops spaces
Yves Felix,Jean-Claude Thomas
Mathematics , 2002,
Abstract: Let M be a simply-connected closed oriented N-dimensional manifold. We prove that for any field of coefficients there exists a natural homomorphism of commutative graded algebras $\Psi : H_\ast (\Omega {aut}_1 M) \to H_{\ast +N}(M^{S^1})$ where $H_\ast (M^{S^1})$ is the loop algebra defined by Chas-Sullivan. As usual ${aut}_1 X$ (resp. $\Omega X$) denotes the monoid of the self-equivalences homotopic to the identity map (resp. the space of based loops) of the space X. Moreover, if $\bk$ is of characteristic zero, $\Psi$ yields isomorphisms $\pi_n(\Omega {aut}_1 M) \otimes \bk \cong \hH^{n+N}_{(1)}$ where $\displaystyle \oplus_{l=1}^\infty \hH^n_{(l)}$ denotes the Hodge decomposition on $H^\ast (M ^{S^1})$.
