MARIJUANA SMOKING AMONG SECONDARY SCHOOL STUDENTS IN ZARIA, NIGERIA: FACTORS RESPONSIBLE AND EFFECTS ON ACADEMIC PERFORMANCE

Background: The use of Marijuana is on the increase worldwide especially among adolescents and youths. Marijuana smoking has gained a foothold in our environment because of peer group influence, accessibility and availability. Its medico-social effects could ruin the life and future of our youths. This study was undertaken to determine the prevalence and the factors that influence secondary school students in Zaria LGA to smoke and the effects on academic performance. Methods: A cross-sectional descriptive study was employed to generate data among secondary schoolstudents. A multi-stage sampling technique was used. Data was collected with the use of a structured, pre tested self-administered questionnaire. ƒÓ2 test was used to test for significance of associationbetween categorical variables. Results: Of the 350 respondents, 262 (74.9%) were males, while 88 (25.1%) were females. The studyshows that 33 of the students smoke marijuana giving a prevalence of 9.4%. There were more smokers in the age group 15-19 years (54.6%). Other factors that influence marijuana smoking include familybackground, peer pressure and attendance of social functions. There was better academic performance (51.1%) among non smokers as compared to smokers (27.2%), and this was found to be statisticallysignificant (x2 = 11.73,df = 5,P < .05) There was also statistically significant association between age and marijuana smoking (x2 = 24,df = 2,P < .05) Conclusion: The prevalence of marijuana smoking is high. Age, family background, peer pressure and attendance of social function influence marijuana smoking. A comprehensive school health educationprogram should be instituted to curtail this menac

Household Barriers to Effective Malaria Prevention and Control in a Rural Community of North-Western Nigeria

Background: Malaria is endemic throughout Nigeria. Majority of Nigerians live in rural areas where subsistence farming is their main occupation. Most of them live below poverty line, earning less than $1.25 a day. In rural communities, many household factors constitute barriers to effective malaria prevention and control.Objective: This study was conducted to assess the factors that constitute barriers to prevention and control of malaria in Gimba village, a rural community in Soba Local Government area of Kaduna State, Nigeria.Methodology: A cross-sectional descriptive study conducted during community diagnosis posting of final year medical students of Ahmadu Bello University, Zaria in July 2012. An interviewer- administered questionnaire was used to collect data from the total population of household heads in the community.Results: Of the 686 respondents, most were farmers (69.7%). In terms of malaria prevention, most of the households (81.8%) own a mosquito net, but in 40.8% of the households, no member slept under a mosquito net the night before the survey. A significant proportion of the households (32.9%) use “otapiapia”, a cheap, unpatented, locally made pesticide as mosquito repellent, while 20.7% of the households do not use any method for malaria prevention. Respondents that had formal education, or with less than 5 children were more likely to use malaria preventive methods compared to those with no formal education or with more than 5 children. Regarding malaria treatment, most of the households, 73%, treated their last cases of presumptive malaria at chemist shops.Conclusion: Some socio-demographic characteristics of respondents and household practices militate against effective malaria prevention and control in the study area. Health Education and Socioeconomic Development in rural areas are recommended for successful malaria prevention and control.Keywords: Household, Barriers, Malaria, Prevention, Rural Community, Nigeri

Household Expenditure on Treatment of Presumptive Malaria in a Rural Community of North-western Nigeria

Background: Malaria is endemic in Nigeria and there is a vicious cycle between it and poverty. It contributes towards poverty, while poverty influences the risk of its infection. Majority of Nigerians, 70%, live in rural areas, below poverty line. They earn less than $1.25 a day. Subsistence farming is their main occupation. The cost of malaria treatment represents a significant portion of their income.Objective: This study was conducted to assess the direct cost of presumptive malaria treatment on households in Gimba Village of Soba Local Government Area of Kaduna State, Nigeria.Methodology: A cross-sectional descriptive study conducted during community diagnosis posting of final year medical students of Ahmadu Bello University, Zaria in July 2012. An interviewer- administered questionnaire was used to collect data from household heads.Results: Most of the respondents (69.7%) were farmers. A large proportion of the respondents (47.3%) earned between N10,000.00 to N20,000.00. monthly. The average household size was 6 while the average number of presumptive malaria cases per household per year was 13. On average, the direct cost of presumptive malaria treatment alone, consumes 4.9 % of the annual income of household heads. There was a statistically significant association between cost of treatment and place of seeking treatment (p &lt;0.001).Conclusion: The direct cost of presumptive malaria treatment alone consumed a large proportion of the meagre annual income of households in the study area. For effective malaria control in Nigeria, free or subsidized malaria treatment and rural health insurance scheme are recommended.Keywords: Household, expenditure, Treatment, presumptive malaria, Gimba Community, Nigeria

Smaller self-inflating bags produce greater guideline consistent ventilation in simulated cardiopulmonary resuscitation

<p>Abstract</p> <p>Background</p> <p>Suboptimal bag ventilation in cardiopulmonary resuscitation (CPR) has demonstrated detrimental physiological outcomes for cardiac arrest patients. In light of recent guideline changes for resuscitation, there is a need to identify the efficacy of bag ventilation by prehospital care providers. The objective of this study was to evaluate bag ventilation in relation to operator ability to achieve guideline consistent ventilation rate, tidal volume and minute volume when using two different capacity self-inflating bags in an undergraduate paramedic cohort.</p> <p>Methods</p> <p>An experimental study using a mechanical lung model and a simulated adult cardiac arrest to assess the ventilation ability of third year Monash University undergraduate paramedic students. Participants were instructed to ventilate using 1600 ml and 1000 ml bags for a length of two minutes at the correct rate and tidal volume for a patient undergoing CPR with an advanced airway. Ventilation rate and tidal volume were recorded using an analogue scale with mean values calculated. Ethics approval was granted.</p> <p>Results</p> <p>Suboptimal ventilation with the use of conventional 1600 ml bag was common, with 77% and 97% of participants unable to achieve guideline consistent ventilation rates and tidal volumes respectively. Reduced levels of suboptimal ventilation arouse from the use of the smaller bag with a 27% reduction in suboptimal tidal volumes (p = 0.015) and 23% reduction in suboptimal minute volumes (p = 0.045).</p> <p>Conclusion</p> <p>Smaller self-inflating bags reduce the incidence of suboptimal tidal volumes and minute volumes and produce greater guideline consistent results for cardiac arrest patients.</p

Targeted Inactivation of Rin3 Increases Trabecular Bone Mass by Reducing Bone Resorption and Favouring Bone Formation

AbstractCommon genetic variants at the RIN3 locus on chromosome 14q32 predispose to Paget’s disease of bone (PDB) but the mechanisms by which they do so are unknown. Here, we analysed the skeletal phenotype of female mice with targeted inactivation of the mouse Rin3 gene (Rin3−/−) as compared with wild-type littermates. The Rin3−/− mice had higher trabecular bone volume (BV/TV%) compared with wild type. Mean ± standard deviation values at the distal femur at 8 weeks were 9.0 ± 2.5 vs. 7.0 ± 1.5 (p = 0.002) and at 52 weeks were 15.8 ± 9.5 vs. 8.5 ± 4.2 (p = 0.002). No differences were observed in femoral cortical bone parameters with the exception of marrow diameter which was significantly smaller in 52-week-old Rin3−/− mice compared to wild type: (0.43 mm ± 0.1 vs. 0.57 mm ± 0.2 (p = 0.001). Bone histomorphometry showed a lower osteoclast surface / bone surface (Oc.S/BS%) at 8 weeks in Rin3−/− mice compared to wild type (24.1 ± 4.7 vs. 29.7 ± 6.6; p = 0.025) but there were no significant differences in markers of bone formation at this time. At 52 weeks, Oc.S/BS did not differ between genotypes but single labelled perimeter (SL.Pm/B.Pm (%)) was significantly higher in Rin3−/− mice (24.4 ± 6.4 vs. 16.5 ± 3.8, p = 0.003). We conclude that Rin3 negatively regulates trabecular bone mass in mice by inhibiting osteoclastic bone resorption and favouring bone formation. Our observations also suggest that the variants that predispose to PDB in humans probably do so by causing a gain-in-function of RIN3.</jats:p

Determinants of the exclusive breastfeeding abandonment: psychosocial factors

OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90), 47.6% (n = 80), and 69.6% (n = 117), respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process
