The black soldier fly, Hermetia illucens (Diptera: Stratiomyidae): Trapping and culturing of wild colonies in Ghana
The larvae of the black soldier fly (BSF), Hermetia illucens L. (Diptera: Stratiomyidae), are promising candidates to be utilized in alternative organic waste management and for fish and livestock feed production. The scalability of this technology in Ghana will depend on a steady source of large numbers of BSF larvae. The objectives of this study were to identify the most attractive organic manure dumps or heaps in the study area for trapping wild BSF egg clutches and assess the effect of local environmental conditions on the trapping and laboratory rearing of BSF. The study compared the number of egg clutch trapped at different microhabitats including piggery, chicken and sheep waste dumps and on a compost heap. The piggery dump waste was the most suitable site for trapping BSF egg clutches. No egg clutch was deposited nearby poultry and sheep waste microhabitats. Results showed no differences in temperature between microhabitats during egg trapping but relative humidity differed between poultry, sheep and compost, however this did not have any effect on egg clutch trapping. No significant differences in temperature and humidity were observed during larval rearing. Significant differences in weight and length of larvae from both piggery and compost sites were observed on days 5 and 10 after egg hatch. A small scale laboratory colony rearing has been successfully established in Ghana. The design of the larval breeding system appears to be suitable for respective up-scaling that could provide sufficient larval quantities for composting organic waste and producing feed components for livestock and fish
Extracellular ATP triggers proteolysis and cytosolic Ca²⁺ rise in Plasmodium berghei and Plasmodium yoelii malaria parasites.
BACKGROUND: Plasmodium has a complex cell biology and it is essential to dissect the cell-signalling pathways underlying its survival within the host. METHODS: Using the fluorescence resonance energy transfer (FRET) peptide substrate Abz-AIKFFARQ-EDDnp and Fluo4/AM, the effects of extracellular ATP on triggering proteolysis and Ca²⁺ signalling in Plasmodium berghei and Plasmodium yoelii malaria parasites were investigated. RESULTS: The protease activity was blocked in the presence of the purinergic receptor blockers suramin (50 μM) and PPADS (50 μM) or the extracellular and intracellular calcium chelators EGTA (5 mM) and BAPTA/AM (25, 100, 200 and 500 μM), respectively for P. yoelii and P. berghei. Addition of ATP (50, 70, 200 and 250 μM) to isolated parasites previously loaded with Fluo4/AM in a Ca²⁺-containing medium led to an increase in cytosolic calcium. This rise was blocked by pre-incubating the parasites with either purinergic antagonists PPADS (50 μM), TNP-ATP (50 μM) or the purinergic blockers KN-62 (10 μM) and Ip5I (10 μM). Incubating P. berghei infected cells with KN-62 (200 μM) resulted in a changed profile of merozoite surface protein 1 (MSP1) processing as revealed by western blot assays. Moreover incubating P. berghei for 17 h with KN-62 (10 μM) led to an increase in rings forms (82% ± 4, n = 11) and a decrease in trophozoite forms (18% ± 4, n = 11). CONCLUSIONS: The data clearly show that purinergic signalling modulates P. berghei protease(s) activity and that MSP1 is one target in this pathway
Socio-economic and geographical inequalities in adolescent fertility rate in Ghana, 1993–2014
Background
Despite public health interventions to control adolescent fertility, it remains high in sub-Saharan Africa. Ghana is one of the countries in sub-Saharan Africa with the highest adolescent fertility rates. We examined the trends and socio-economic and geographical patterns of disparities in adolescent fertility in Ghana from 1993 to 2014.
Methods
Using the World Health Organization’s (WHO) Health Equity Assessment Toolkit (HEAT) software, data from the 1993–2014 Ghana Demographic and Health surveys were analyzed. First, we disaggregated adolescent fertility rates (AFR) by four equity stratifiers: wealth index, education, residence and region. Second, we measured the inequality through summary measures, namely Difference (D), Population Attributable Risk (PAR), Ratio (R) and Population Attributable Fraction (PAF). A 95 % confidence interval was constructed for point estimates to measure statistical significance.
Results
We observed substantial absolute and relative wealth-driven inequality in AFR (PAR=-47.18, 95 % CI; -49.24, -45.13) and (PAF= -64.39, 95 % CI; -67.19, -61.59) respectively in favour of the economically advantaged subpopulations. We found significant absolute (D = 69.56, 95 % CI; 33.85, 105.27) and relative (R = 3.67, 95 % CI; 0.95, 6.39) education-based inequality in AFR, with higher burden of AFR among disadvantaged subpopulations (no formal education). The Ratio measure (R = 2.00, 95 % CI; 1.53, 2.47) indicates huge relative pro-urban disparities in AFR with over time increasing pattern. Our results also show absolute (D, PAR) and relative (R, PAF) inequality in AFR across subnational region, between 2003 and 2014. For example, in the 2014 survey, the PAR measure (D=-28.22, 95 % CI; -30.58, -25.86) and the PAF measure (PAF=-38.51, 95 % CI; -41.73, -35.29) indicate substantial absolute and relative regional inequality.
Conclusions
This study has indicated the existence of inequality in adolescent fertility rate in Ghana, with higher ferlitiy rates among adolescent girls who are poor, uneducated, rural residents and those living in regions such as Northern, Brong Ahafo, and Central region, with increasing disparity over the time period of the study. There is the need for policy interventions that target adolescent girls residing in the rural areas and those in the low socioeconomic subgroups to enable the country to avert the high maternal/newborn morbidity and mortality usually associated with adolescent childbearing
Trend and determinants of complete vaccination coverage among children aged 12-23 months in Ghana: Analysis of data from the 1998 to 2014 Ghana Demographic and Health Surveys.
BackgroundVaccination is proven to be one of the most cost-effective measures adopted to improve the health of children globally. Adhering to vaccines for children has the propensity to prevent about 1.5 million annual child deaths globally. This study sought to assess the trend and determinants of complete vaccination coverage among children aged 12-23 months in Ghana.Materials and methodsThe study was based on data from four rounds of the Ghana Demographic and Health Survey (GDHS 1998, 2003, 2008, and 2014). Information on 5,119 children aged 12-23 months were extracted from the children's files. Both bivariate and multivariate analyses were conducted to assess the factors associated with complete vaccination and statistical significance was pegged at pResultsWe found that complete vaccination coverage increased from 85.1% in 1998 to 95.2% in 2014. Children whose mothers were in rural areas [aOR = 0.45; CI = 0.33-0.60] had lower odds of getting complete vaccination, compared to those whose mothers were in urban areas. Also, children whose mothers had a secondary level of education [aOR = 1.87; CI = 1.39-2.50] had higher odds of receiving complete vaccination, compared to those whose mothers had no formal education. Children whose mothers were either Traditionalists [aOR = 0.60; CI = 0.42-0.84] or had no religion [aOR = 0.58, CI = 0.43-0.79] had lower odds of receiving complete vaccination, compared to children whose mothers were Christians.ConclusionThe study revealed that there has been an increase in the coverage of complete vaccination from 1998 to 2014 in Ghana. Mother's place of residence, education, and religious affiliation were significantly associated with full childhood vaccination. Although there was an increase in complete childhood vaccination, it is imperative to improve health education and expand maternal and child health services to rural areas and among women with no formal education to further increase complete vaccination coverage in Ghana
Does Birth Interval Matter in Under-Five Mortality? Evidence from Demographic and Health Surveys from Eight Countries in West Africa
In sub-Saharan Africa (SSA), every 1 in 12 children under five dies every year compared with 1 in 147 children in the high-income regions. Studies have shown an association between birth intervals and pregnancy outcomes such as low birth weight, preterm birth, and intrauterine growth restriction. In this study, we examined the association between birth interval and under-five mortality in eight countries in West Africa. A secondary analysis of the Demographic and Health Survey (DHS) data from eight West African countries was carried out. The sample size for this study comprised 52,877 childbearing women (15-49 years). A bivariate logistic regression analysis was carried out and the results were presented as crude odds ratio (cOR) and adjusted odds ratios (aOR) at 95% confidence interval (CI). Birth interval had a statistically significant independent association with under-five mortality, with children born to mothers who had >2 years birth interval less likely to die before their fifth birthday compared to mothers with ≤2 years birth interval [cOR = 0:56; CI = 0:51 − 0:62], and this persisted after controlling for the covariates [aOR = 0:55; CI = 0:50 − 0:61]. ]. The country-specific results showed that children born to mothers who had >2 years birth interval were less likely to die before the age of five compared to mothers with ≤2 years birth interval in all the eight countries. In terms of the covariates, wealth quintile, mother’s age, mother’s age at first birth, partner’s age, employment status, current pregnancy intention, sex of child, size of child at birth, birth order, type of birth, and contraceptive use also had associations with under-five mortality. We conclude that shorter birth intervals are associated with higher under-five mortality. Other maternal and child characteristics also have associations with under-five mortality. Reproductive health interventions aimed at reducing under-five mortality should focus on lengthening birth intervals. Such interventions should be implemented, taking into consideration the characteristics of women and their childre
Understanding the linkages between male circumcision and multiple sexual partnership among married Ghanaian men: Analysis of data from the 2014 Ghana demographic and health survey.
IntroductionThis current study sought to investigate the association between male circumcision status and engaging in multiple sexual partnership among men in Ghana.MethodsData from this study come from the men's file of the 2014 Ghana demographic and health survey. Both descriptive and inferential statistics were conducted among 1, 948 men and the level of statistical significance was pegged at p ResultsResults revealed that men who have been circumcised were more likely to engage in multiple sexual partnership (AOR = 3.36; CI:1.14-9.89), compared to those who have not been circumcised. With the covariates, men with primary level of education were more likely to have multiple sexual partners (AOR = 2.01; CI:1.10-3.69), compared to those with no education. With wealth status, men with richest (AOR = 2.27; CI:1.04-4.97), richer (AOR = 2.05; CI: 1.03-4.08), and middle wealth status (AOR = 1.83; CI:1.01-3.34) had the highest likelihood of having multiple sexual partners, compared to those with poorest wealth status. Conversely, men who professed the Islamic faith were less likely to engage in multiple sexual partnership (AOR = 0.58; CI: 0.36-0.94), compared to Christians. Similarly, men who resided in the Brong Ahafo (AOR = 0.51; CI: 0.26-0.99), Upper East (AOR = 0.41; CI:0.19-0.89), and Ashanti regions (AOR = 0.39; CI: 0.20-0.78) were less likely to engage in multiple sexual partnership.ConclusionBased on the current findings, educational campaigns by stakeholder groups (e.g., Ministry of Health in collaboration with the National Commission on Civic Education, civil society, educational institutions) should sensitize the sexually active population at the community level to consistently use condoms, especially when they have multiple sexual partners, even when a man is circumcised. Campaign messages must clearly emphasize that male circumcision should not substitute precautionary measures such as delay in the onset of sexual relationships, averting penetrative sex, reducing the number of sexual partners as well as correct and consistent use of male or female condoms regardless one's social standing
Awareness of obstetric fistula and its associated factors among women of reproductive age in sub-Saharan Africa.
BACKGROUND: Awareness about obstetric fistula and its concomitant factors is central to efforts to eliminate obstetric fistula in sub-Saharan Africa. We, therefore, assessed the magnitude of obstetric fistula awareness and its associated factors among women of reproductive age in sub-Saharan Africa. METHODS: Data for the study were extracted from the most recent Demographic and Health Surveys of 14 countries in sub-Saharan Africa. We included 185,388 women aged 15-49 years in this study. Percentages were used to summarise the prevalence of obstetric fistula awareness across the 14 countries studied. We adopted a multivariable multilevel binary logistic regression to examine the factors associated with obstetric fistula awareness in sub-Saharan Africa. We presented the results of the regression analysis using adjusted odds ratios with their 95% confidence intervals. Statistical significance was set at p < 0.05. RESULTS: The average prevalence of obstetric fistula awareness was 37.9%, ranging from 12.8% in Gambia to 63.9% in Uganda. Awareness of obstetric fistula was low among never married and cohabiting women compared to married women. Compared with women with parity 4 or more, those with no birth had the lowest odds of obstetric fistula awareness. The study also showed that obstetric fistula awareness was lower among women who were working, those who are not exposed to mass media, those in the poorest wealth category, those who have never had sex, and those in communities with low literacy level. The study however found that the odds of obstetric fistula awareness increased with age and education, and was higher in urban areas compared to rural areas. Women, who had ever terminated a pregnancy were more likely to be aware of obstetric fistula compared to those who had never terminated a pregnancy. CONCLUSION: The study demonstrated a low awareness of obstetric fistula among women in sub-Saharan Africa. Educative and sensitisation interventions should incorporate the factors identified in the present study during its implementation. To raise women's awareness of obstetric fistula, there is the need for sub-Saharan African countries to consciously raise community literacy rate, increase access to mass media platforms and invest intensively in formal education for women
Beyond counting induced abortions, miscarriages and stillbirths to understanding their risk factors: analysis of the 2017 Ghana maternal health survey
BackgroundInasmuch as induced abortions, miscarriages and stillbirths constitute common adverse pregnancy outcomes contributing to poor maternal health, there is paucity of literature about these in Ghana. We investigated the factors associated with induced abortions, miscarriages and stillbirths in Ghana.MethodsData derived from the 2017 Ghana Maternal Health Survey was used in this study. Women aged 15-49 constituted the target for the study. This study examined the relationship between socio-demographic characteristics and induced abortions, stillbirths and miscarriages. Subsequently, multivariable binary logistic regression models were fitted to investigate the factors associated with induced abortions, stillbirths and miscarriages at 95 % confidence interval (CI).ResultsThe prevalence of miscarriages, induced abortions and stillbirths in Ghana in 2017 were 10.8 %, 10.4 % and 2 % respectively. Induced abortions (12.9 %) and miscarriages (11.1 %) were found to be higher among urban residents whiles rural residents had more of stillbirths (2.1 %). Compared to women aged 15-24, those in all age categories had lower odds of experiencing induced abortions, with the lowest odds occurring among women aged 35-49 (AOR = 0.26, 95 % CI = 0.21-32). Conversely, women of all age categories had higher odds of experiencing miscarriages compared to those aged 15-24 with the highest odds among those aged 25-34 (AOR = 1.62, 95 % CI = 1.39-1.89). Women with at least primary education were more likely to experience miscarriages than those with no formal education, with those with higher level of education having the highest odds (AOR = 1.42, 95 % CI = 1.13-1.78). While the likelihood of induced abortions was lower among Muslims, compared to Christians (AOR = 0.65, 95 % CI = 0.52-0.82), the odds of miscarriages were higher among Muslims, compared to Christians (AOR = 1.31, 95 % CI = 1.13-1.52). Women with parity 1 or more were less likely to experience induced abortions, miscarriages and stillbirths compared to those with parity 0.ConclusionsOur study indicates that efforts to limit induced abortions, miscarriages and stillbirths in Ghana need to focus on the disparities in socio-demographic characteristics of women. Synergy between government health institutions and the private sector cannot be left out if much success can be achieved in efforts to subside the current prevalence of induced abortions, stillbirths and miscarriages confronting the country
