Control of yam tuber rot with leaf extracts of Xylopia aethiopica and Zingiber officinale

Investigation was carried out to test the potency of some plant extracts for the control of yam tuber rot caused by Fusarium oxysporum, Aspergillus niger and Aspergillus flavus. Hot water extracts were obtained from leaf and seed of uda (Xylopia aethiopica) and Ginger (Zinigiber officinale), and were found to be fungitoxic against the fungi. The extracts of suppressed the growth of these fungi in culture and reduced rot development in yam tubers. Key words: Xylopia aethiopica, Zinigiber officinale, ginger, yam tuber rot.African Journal of Biotechnology Vol. 4 (8), pp. 804-80

Risk Factors for Transactional Sex among Young Females in Post-Conflict Liberia

This study aimed to examine the risk factors for engaging in transactional sex among young females in Montserrado County, Liberia. Data from an HIV behavioral survey conducted among young people aged 14 – 25 years were used. The analytical sample included 493 sexually-experienced females. Bivariate and multivariate analyses were conducted. We found that 72% of our sample had ever engaged in transactional sex. Engagement in transactional sex was associated with education (OR: 0.5); reporting no earned income (OR: 1.9); longer duration of sexual activity (OR: 3.5); early sexual debut (OR: 2.5); history of sexual violence (OR: 2.1) and multiple sexual partnerships (OR: 4.0). Respondents' age, residence, and drug/alcohol use were not associated with engagement in transactional sex. HIV interventions should incorporate educational strategies to reduce the prevalence of transactional sex among young people. These strategies should include economic opportunities to offset financial need as well as efforts to eradicate sexual violence.

Low cost air quality monitoring: comparing the energy consumption of an arduino against a raspberry Pi based system

Air pollution is one of the great challenges facing modern cities. According to the World Health Organization (WHO), 80% of people living in cities with air quality monitoring facilities are living in conditions where the quality of the air is well beyond the limits set out in the air quality guidelines. As more and more people are projected to move into urban areas by 2050, this problem is going to keep on increasing. A possible solution could be the advent of Smart Cities. One of the objectives of Smart Cities is to provide a better living environment to its inhabitants. With the Internet of Things providing easily deployable, low power, low cost air quality monitoring sensors and the resources to process the huge amount of data collected, this objective could be reached. In this paper, we propose an evaluation of the power consumption of two low cost air quality monitoring systems - one based on an Arduino and the other on a Raspberry Pi system. The air quality systems proposed are based on off-the shelf hardware and are easy to assemble and maintain. The proposed systems use Bluetooth Low Energy (BLE) to transmit data while being collected through a mobile app on a smartphone. The data was collected for five days and it was found by performing an ANOVA on the power consumption that there was a significant difference in the mean energy consumption of the two systems

Strengthening Primary Health Care Services in Rural Nigeria: The Potential of Using Midwives as Skilled Birth Attendants

Introduction: The study objective was to assess the potential of using midwives as skilled birth attendants in providing access to maternal health services in rural Nigeria using the Subsidy Reinvestment and Empowerment programme on Maternal and Child Health (SURE P MCH). Method: Baseline survey of 1000 primary health care (PHC) facilities located across all states in the country was conducted before the programme started in 2012. Improvements made on the core indicators for maternal health services were assessed after a follow-up survey. The survey results were also compared to data from rural areas from the 2013 National Demographic Health Survey (NDHS) report. Findings: Total number of antenatal care (ANC) visits at follow-up survey increased by 42%, new ANC visits increased by 39% and four or more ANC visits increased by 30%. Births by skilled birth attendants were up by 56%, postnatal visits increased by 33% and number of women using contraceptive methods increased by 66%. When compared to data from the 2013 NDHS, access to skilled birth attendant and use of modern contraceptives were significant at p<0.0001. Access to antenatal and postnatal services were not significant. The median scores for the core indicators from the geographical zones were significant at p<0.05. Key Conclusions and Implications for practice: Women are more likely to have more supervised births and use more contraceptives in rural facilities when midwifery services are present. The programme model has the potential to strengthen and improve access to maternal health services in rural communities where the need is greatest.

Growing Up at the “Margins”: Concerns, Aspirations, and Expectations of Young People Living in Nairobi's Slums

We explore the concerns, challenges, aspirations, and expectations of sub-Saharan African youth, and investigate how these youth cope with neighborhood constraints to aspiration achievement. We draw on cross-sectional survey data from 4033 12-22 year olds (50.3% males) from two Kenyan urban slums and subsequent in-depth interviews conducted with a subset of 75 youth when they were 13-24 years old (45.3% male). We observe that despite the challenges characteristic of urban slums, some youth maintain high aspirations and try to achieve them through education, delinquency, residential mobility, and religion. We note that others adjust their aspirations to account for limited opportunities. Overall, our findings highlight positive youth agency and underscore the need to improve the quality of life in urban slums

Influence of parental factors on adolescents’ transition to first sexual intercourse in Nairobi, Kenya: a longitudinal study

Abstract Background Several studies have demonstrated a link between young people’s sexual behavior and levels of parental monitoring, parent-child communication, and parental discipline in Western countries. However, little is known about this association in African settings, especially among young people living in high poverty settings such as urban slums. The objective of the study was to assess the influence of parental factors (monitoring, communication, and discipline) on the transition to first sexual intercourse among unmarried adolescents living in urban slums in Kenya. Methods Longitudinal data collected from young people living in two slums in Nairobi, Kenya were used. The sample was restricted to unmarried adolescents aged 12–19 years at Wave 1 (weighted n = 1927). Parental factors at Wave 1 were used to predict adolescents’ transition to first sexual intercourse by Wave 2. Relevant covariates including the adolescents’ age, sex, residence, school enrollment, religiosity, delinquency, and peer models for risk behavior were controlled for. Multivariate logistic regression models were used to assess the associations of interest. All analyses were conducted using Stata version 13. Results Approximately 6 % of our sample transitioned to first sexual intercourse within the one-year study period; there was no sex difference in the transition rate. In the multivariate analyses, male adolescents who reported communication with their mothers were less likely to transition to first sexual intercourse compared to those who did not (p < 0.05). This association persisted even after controlling for relevant covariates (OR: ≤0.33; p < 0.05). However, parental monitoring, discipline, and communication with their fathers did not predict transition to first sexual intercourse for male adolescents. For female adolescents, parental monitoring, discipline, and communication with fathers predicted transition to first sexual intercourse; however, only communication with fathers remained statistically significant after controlling for relevant covariates (OR: 0.30; 95 % C.I.: 0.13–0.68). Conclusion This study provides evidence that cross-gender communication with parents is associated with a delay in the onset of sexual intercourse among slum-dwelling adolescents. Targeted adolescent sexual and reproductive health programmatic interventions that include parents may have significant impacts on delaying sexual debut, and possibly reducing sexual risk behaviors, among young people in high-risk settings such as slums

Biopsychosocial risk factors and knowledge of cervical cancer among young women: A case study from Kenya to inform HPV prevention in Sub-Saharan Africa

Background: Cervical cancer is the second most common female reproductive cancer after breast cancer with 84% of the cases in developing countries. A high uptake of human papilloma virus (HPV) vaccination and screening, and early diagnosis leads to a reduction of incidence and mortality rates. Yet uptake of screening is low in Sub-Saharan Africa and there is an increasing number of women presenting for treatment with advanced disease. Nine women in their twenties die from cervical cancer in Kenya every day. This paper presents the biopsychosocial risk factors that impact on cervical cancer knowledge among Kenyan women aged 15 to 24 years. The findings will highlight opportunities for early interventions to prevent the worrying prediction of an exponential increase by 50% of cervical cancer incidences in the younger age group by 2034. Methods: Data from the 2014 Kenya Demographic and Health Survey (KDHS) was analysed using complex sample logistic regression to assess biopsychosocial risk factors of knowledge of cervical cancer among young women aged 15 to 24 years (n = 5398). Findings: Close to one third of the participants were unaware of cervical cancer with no difference between participants aged 15–19 years (n = 2716) and those aged 20–24 years (n = 2691) (OR = 1; CI = 0.69–1.45). Social predisposing factors, such as lack of education; poverty; living further from a health facility; or never having taken a human immunodeficiency virus (HIV) test, were significantly associated with lack of awareness of cervical cancer (p<0.001). Young women who did not know where to obtain condoms had an OR of 2.12 (CI 1.72–2.61) for being unaware of cervical cancer. Psychological risk factors, such as low self-efficacy about seeking medical help, and an inability to refuse unsafe sex with husband or partner, perpetuated the low level of awareness about cervical cancer (p<0.001). Conclusions: A considerable proportion of young women in Kenya are unaware of cervical cancer which is associated with a variety of social and psychological factors. We argue that the high prevalence of cervical cancer and poor screening rates will continue to prevail among older women if issues that affect young women’s awareness of cervical cancer are not addressed. Given that the Kenyan youth are exposed to HPV due to early sexual encounters and a high prevalence of HIV, targeted interventions are urgently needed to increase the uptake of HPV vaccination and screening

Informing HIV prevention efforts targeting Liberian youth: a study using the PLACE method in Liberia

BACKGROUND: Preventing HIV infection among young people is a priority for the Liberian government. Data on the young people in Liberia are scarce but needed to guide HIV programming efforts. METHODS: We used the Priorities for Local AIDS Control Efforts (PLACE) method to gather information on risk behaviors that young people (ages 14 to 24) engage in or are exposed to that increase their vulnerability for HIV infection. Community informants identified 240 unique venues of which 150 were visited and verified by research staff. 89 of the 150 venues comprised our sampling frame and 571 females and 548 males were interviewed in 50 venues using a behavioral survey. RESULTS: Ninety-one percent of females and 86% of males reported being sexually active. 56% of females and 47% of males reported they initiated sexual activity before the age of 15. Among the sexually active females, 71% reported they had received money or a gift for sex and 56% of males reported they had given money or goods for sex. 20% of females and 6% males reported that their first sexual encounter was forced and 15% of females and 6% of males reported they had been forced to have sex in the past year. Multiple partnerships were common among both sexes with 81% females and 76% males reporting one or more sex partners in the past four weeks. Less than 1% reported having experiences with injecting drugs and only 1% of males reporting have sex with men. While knowledge of HIV/AIDS was high, prevention behaviors including HIV testing and condom use were low. CONCLUSION: Youth-focused HIV efforts in Liberia need to address transactional sex and multiple and concurrent partnerships. HIV prevention interventions should include efforts to meet the economic needs of youth
