Knowledge, practices and beliefs of students regarding health effects of shisha use in Ouagadougou, Burkina Faso: A cross‐sectional study

Background. The tobacco epidemic is one of the biggest public health threats the world has ever faced. Shisha use has recently been gaining increased popularity in many developed and developing countries. Objective. To determine the prevalence of shisha use among students in Ouagadougou, Burkina Faso, and associated knowledge, smoking practices and beliefs about health effects. Method. A total of 443 students were selected for this cross-sectional study, using a stratified sampling method. Data on shisha use, knowledge about shisha, shisha smoking practices, and factors associated with use of shisha were collected via a questionnaire. The association between the independent variables and shisha use was assessed using a χ2 test (p<0.05). Binary logistic regression analysis was used to determine variables that were independently associated with shisha smoking. Results. Of the 421 respondents, 162 (38.5%) indicated that they had smoked shisha; 14.0% were regular smokers. We found that 183 students (43.5%) had poor knowledge about the health effects of shisha. The main reasons for shisha smoking were being in the company of friends who were users (57.4%), the pleasant flavour and fragrance of shisha (25.9%), and fashion (22.2%). Ninety-nine shisha smokers (61.1%) also consumed alcohol. Factors associated with shisha smoking included age <20 years (p<0.001), gender (p=0.034), and educational level of the respondent’s father (p=0.0001) and mother (p=0.0004). Conclusion. We found a relatively high prevalence of shisha smoking among the students, and that 43.5% of them had poor knowledge about its effects on health. Developing surveillance, intervention and regulatory/policy frameworks specific to shisha has become a public health priority

Hepatoprotective activity of aqueous extract of Balanites aegyptiaca L. Delile (Balanitaceae) roots bark

Balanites aegyptiaca (L.) Del (Balanitaceae) is traditionally used for the treatment of various ailments such as syphilis, jaundice and liver disorders, epilepsy, ... This study was designed to evaluate acute toxicity and hepatoprotective effect of aqueous extract of Balanites aegyptiaca on CCl4 induced hepatotoxicity in rats.Methods: Acute toxicity was assessed with the extract at a dose of 2000 mg / kg bw. The extract at doses of 25, 50 and 100 mg / kg b.w. was orally administered respectively to CC14-induced hepatotoxicity (0.5 ml / kg) animals. Silymarin (100 mg / kg) was given as a reference. Biochemical parameters such as ALT, AST, PT, ALB and ALP were assayed as well as enzymatic antioxidant activities SOD, CAT and MDA. Nitrogen monoxide (NO) involved in inflammation was also measured.Results: Activities of liver marker enzymes, ALT, AST and ALP, total protein, albumin and showed a significant hepatoprotective effect. Regarding antioxidant enzymatic activities in vivo (SOD, CAT and MDA) of aqueous extract exhibited a significant effect showing increasing levels of SOD, CAT and reducing malondialdehyde (MDA) levels. The production of NO is significantly reduced compared to the batch intoxicated by CCl4.Conclusion: Balanites aegyptiaca is endowed with hepatoprotective properties that can be attributed to antioxidant potential which could justify its use in traditional medicine in liver disorders

Antioxidant properties and subchronic toxicity of the standardized extract of LAMIC, a phytomedicine prototype based on aqueous extracts from trunk bark of Lannea microcarpa Engl and K. Krause

Aims: This study investigated the antioxidant activity and the 90 days subchronic toxicity of the standardized LAMIC phytomedicine prototype based on aqueous extracts from Lannea microcarpa trunk bark. Methods: Three spectrophotometric methods were used to evaluated the antioxidant activity of LAMIC which were 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radical, 2,2’-azinobis(3-ethylbenzolin-6-sulphonate) (ABTS) radical scavenging assays and ferric reducing antioxidant power (FRAP) assays. For the standardized LAMIC subchronic toxicity study, male and female Wistar rats were used by daily oral administration at doses of 500, 1000 and 1500 mg/kg bw consecutively for 90 days. Results: The LAMIC extract exhibit better inhibitory activity against DPPH radical than ABTS radical with respective IC50 values of 45.38±3.21 µg/mL and 66.45±18.76 µg/mL, while FRAP assay exhibit antioxidant activity of 211.34±15.92 mmol EAA/g. Subchronic oral administration of LAMIC was well-tolerated at all tested doses. No behavioral and physiological changes and mortality were observed. The LAMIC extract did not present any impact on general hematological parameters and biochemical parameters. Moreover, no significant changes were raised in organ and body weight of treated groups compared to the Control group. Conclusion: These results support that LAMIC prototype was a valuable source of natural antioxidants and no toxicity was associated to its long terms oral consumption in rats indicating a potential application as a cardiovascular protective formulation.

Livestock keepers’ attitudes: Keystone of effective community-based breeding programs

Livestock keepers in southwestern Burkina Faso hold the local Lobi taurine breed, local Zebu cattle, and their crosses. Some communities in the region have begun to implement community-based cattle breeding programs (CBBPs), which involve animal tagging and recording and, potentially, also bull sharing. Based on the hypothesis that the participation of livestock keepers in CBBPs depends on their attitudes towards these programs, we used questionnaires to survey the attitudes of 125 farmers towards cattle breeding strategies and tools. Results were analyzed using principal component analysis. Farmers showed a highly positive attitude towards maintaining the features of their preferred cattle breed, but their attitudes varied substantially towards crossbreeding for breed improvement. Farmers generally agreed that performance was more important than animal appearance, and most of them were willing to cooperate with breeders’ associations but were skeptical about sharing their bulls with other farmers. The majority was reluctant to record performance data, which may be due to a capacity deficit and their confidence in being able to select the best animals based purely on phenotype. Our analysis suggests that breeders’ associations, as a key component of CBBPs, should lay down clear rules and obligations for their members from the outset. Timely consideration of farmers’ attitudes towards different breeding tools may improve their uptake and guarantee the sustainability of CBBPs

Predictors and pathways of language and motor development in four prospective cohorts of young children in Ghana, Malawi, and Burkina Faso

BackgroundPrevious reviews have identified 44 risk factors for poor early child development (ECD) in low- and middle-income countries. Further understanding of their relative influence and pathways is needed to inform the design of interventions targeting ECD.MethodsWe conducted path analyses of factors associated with 18-month language and motor development in four prospective cohorts of children who participated in trials conducted as part of the International Lipid-Based Nutrient Supplements (iLiNS) Project in Ghana (n&nbsp;=&nbsp;1,023), Malawi (n&nbsp;=&nbsp;675 and 1,385), and Burkina Faso (n&nbsp;=&nbsp;1,122). In two cohorts, women were enrolled during pregnancy. In two cohorts, infants were enrolled at 6 or 9&nbsp;months. In multiple linear regression and structural equation&nbsp;models (SEM), we examined 22 out of 44 factors identified in previous reviews, plus 12 additional factors expected to be associated with ECD.ResultsOut of 42 indicators of the 34 factors examined, 6 were associated with 18-month language and/or motor development in 3 or 4 cohorts: child linear and ponderal growth, variety of play materials, activities with caregivers, dietary diversity, and child hemoglobin/iron status. Factors that were not associated with child development were indicators of maternal Hb/iron status, maternal illness and inflammation during pregnancy, maternal perceived stress and depression, exclusive breastfeeding during 6&nbsp;months postpartum, and child diarrhea, fever, malaria, and acute respiratory infections. Associations between socioeconomic status and language development were consistently mediated to a greater extent by caregiving practices than by maternal or child biomedical conditions, while this pattern for motor development was not consistent across cohorts.ConclusionsKey elements of interventions to ensure quality ECD are likely to be promotion of caregiver activities with children, a variety of play materials, and a diverse diet, and prevention of faltering in linear and ponderal growth and improvement in child hemoglobin/iron status

Mortality, morbidity, and developmental outcomes in infants born to women who received either mefloquine or sulfadoxine-pyrimethamine as intermittent preventive treatment of malaria in pregnancy : a cohort study

Background Little is known about the effects of intermittent preventive treatment of malaria in pregnancy (IPTp) on the health of sub-Saharan African infants. We have evaluated the safety of IPTp with mefloquine (MQ) compared to sulfadoxine- pyrimethamine (SP) for important infant health and developmental outcomes. Methods and Findings In the context of a multicenter randomized controlled trial evaluating the safety and efficacy of IPTp with MQ compared to SP in pregnancy carried out in four sub-Saharan countries (Mozambique, Benin, Gabon, and Tanzania), 4,247 newborns, 2,815 born to women who received MQ and 1,432 born to women who received SP for IPTp, were followed up until 12 mo of age. Anthropometric parameters and psychomotor development were assessed at 1, 9, and 12 mo of age, and the incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were determined until 12 mo of age. No significant differences were found in the proportion of infants with stunting, underweight, wasting, and severe acute malnutrition at 1, 9, and 12 mo of age between infants born to women who were on IPTp with MQ versus SP. Except for three items evaluated at 9 mo of age, no significant differences were observed in the psychomotor development milestones assessed. Incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were similar between the two groups. Information on the outcomes at 12 mo of age was unavailable in 26% of the infants, 761 (27%) from the MQ group and 377 (26%) from the SP group. Reasons for not completing the study were death (4% of total study population), study withdrawal (6%), migration (8%), and loss to follow-up (9%). Conclusions No significant differences were found between IPTp with MQ and SP administered in pregnancy on infant mortality, morbidity, and nutritional outcomes. The poorer performance on certain psychomotor development milestones at 9 mo of age in children born to women in the MQ group compared to those in the SP group may deserve further studies
