IMPACT OF SOCIOECONOMICS ON THE LOW ACCESS TO BASIC EDUCATION AMONG GIRLS IN BALI LGA, TARABA STATE NIGERIA
The best asset for developing any society lies on investing in human capital, especially through education. Free basic education has been viewed as a panacea to the development of human capital, especially in the third world countries. One of these countries, such as Nigeria in West Africa, has compulsory policy on free basic education. However, despite heavy investment in the sector, access to basic education for the girl child remains a challenge. The study sought to establish factors influencing low access of the girl-child to free primary education in Nigeria with a focus on Bali Local Government Area (LGA).The researcher used a cross sectional survey research design. An interview schedule and questionnaire were used to collect data. Data collected was analyzed using content analysis and with the help of the Statistical Package for Social Sciences (SPSS) computer programme respectively. Both qualitative and quantitative data was presented using descriptive statistics. The study has established that socio economic and cultural factors have huge influence in inhibiting the girl child’s access to basic education in Bali LGA. It was overwhelmingly (66%) reported that child labour was prevalent in the study area. However, the finding was a reflection of the economic living standards of the households in Bali LGA, where girls were used to support income generation for the households. It emerged during the study that child labour was necessitated by the economic hardships of the parents, drawing its root from poverty, which drives the girls to supplement and boost family income. High (60%) rates of early marriages were also reported in this study. The researcher recommends that the government of Nigeria should introduce new innovative initiatives to control child labour and enforce anti child labour laws. Article visualizations
Metabolic alterations in preneoplastic development revealed by untargeted metabolomic analysis
Metabolic rewiring is a critical hallmark of tumorigenesis and is essential for the development of cancer. Although many key features of metabolic alteration that are crucial for tumor cell survival, proliferation and progression have been identified, these are obtained from studies with established tumors and cancer cell lines. However, information on the essential metabolic changes that occur during pre-neoplastic cell (PNC) development that enables its progression to full blown tumor is still lacking. Here, we present an untargeted metabolomics analysis of human oncogene HRAS(G12V) induced PNC development, using a transgenic inducible zebrafish larval skin development model. By comparison with normal sibling controls, we identified six metabolic pathways that are significantly altered during PNC development in the skin. Amongst these altered pathways are pyrimidine, purine and amino acid metabolism that are common to the cancer metabolic changes that support rapid cell proliferation and growth. Our data also suggest alterations in post transcriptional modification of RNAs that might play a role in PNC development. Our study provides a proof of principle work flow for identifying metabolic alterations during PNC development driven by an oncogenic mutation. In the future, this approach could be combined with transcriptomic or proteomic approaches to establish the detailed interaction between signaling networks and cellular metabolic pathways that occur at the onset of tumor progression
Human papillomavirus type 16 (HPV-16) IgG antibody among women of reproductive age presenting at a healthcare facility in Central Nigeria: a pilot study
Approximately, 70% of cervical cancer cases worldwide are attributable to HPV-16 and HPV-18, with HPV-associated cancers being the second most common infection-related cancers globally. However, there´s paucity of data about this infective agent in Central Nigeria. In a cross-sectional study, we evaluated the seroprevalence of HPV-16 immunoglobulin G (IgG) and risk determinants among women in Central Nigeria as a first step towards evaluating anti-HPV IgM antibody for active cases and determining incidence. Blood samples were collected between August 2016 and January 2018, from 400 consenting women of childbearing age (15-49 years) who completed structured questionnaires. Samples were analyzed using HPV-16 specific IgG ELISA kits (Cusabio Co. Ltd, Germany). Statistical analysis was performed to determine predictors. Overall, we found that 128 (32.0%) had IgG antibody against HPV-16. Seroprevalence by age was 50.0% (15-19 years), 55.0% (20-24 years), 12.9% (25-29 years), 50.0% (30-34 years), 32.1% (35-39 years), 18.2% (40-44 years) and 19.4% (45-49 years) respectively. Factors associated with infection were age (P=0.0002; 95% CI 5.06-31.51), occupation (P<0.0001; 95% CI 1.4-12.6), number of sex partners (P=0.0037; 95% CI 1.27-49.93), history of genital warts (P=0.0203; 95% CI 1.34-9.55) and education level (P<0.0001; 95% CI 3.89-60.11). In addition, forty six (11.5%) reported having the history of genital warts with 268 (67.0%) and 132 (33.0%) subjects being married and single respectively. Individuals who were either artisans or civil servants were 260 (65.0%), whereas 140 (35.0%) were students. Majority, 324 (81.0%), had either primary, secondary or tertiary education with 76 (19.0%) of the subjects having no formal education. In respect of sexual behaviour, 196 (49.0%) reported having at least two sexual partners, out of which 64 (16.0%) had three or more. These findings provide high serological evidence of exposure to HPV-16 in Central Nigeria with implications for national and regional intervention initiatives
Factors associated with burnout among healthcare providers in a rural context, South Africa
Background:Â Healthcare providers (HCPs) are at risk of burnout in sub-Saharan Africa. However, there is little research in rural and primary care settings.
Aim:Â To evaluate burnout and its associated factors among public sector HCPs in South Africa.
Setting:Â Primary health care clinics, community health centres and district hospitals in Nkomazi Local Municipality, Mpumalanga province.
Methods: Quantitative study design using a cross-sectional survey. Healthcare providers (n = 1139) working in Nkomazi Local Municipality were invited to participate. Burnout was assessed using the Maslach Burnout Inventory. A demographic and occupational questionnaire, the General Help-Seeking Questionnaire and the Health and Safety Executive Indicator Tool were used.
Results: A total of 302 HCPs, between 23 and 61 years, mostly female (n = 252; 83.44%) and nurses (n = 235; 77.81%) participated. High burnout was observed for Emotional Exhaustion (median score 26 [IQR {interquartile range}: 34–16]) and Personal Accomplishment (median score 29 [IQR: 34–25]). Most participants (n = 215; 71.19%) would seek help if they had an emotional problem. Bivariate analysis revealed significant associations between workplace demands, control, management support, peer support, relationships, role and change with all subscales of burnout. Multivariate regression analysis found that Personal Accomplishment improved by 0.49 (95% CI: 0.10–0.89) for every point in improved work demands, by 0.84 (95% CI: 0.01–1.67) for every point towards improved management support and by 1.19 (95% CI: 0.48–1.90) for every point towards having an improved role.
Conclusions:Â During 2022, HCPs working in a rural area in South Africa displayed high levels of burnout for Emotional Exhaustion and Personal Accomplishment but not for Depersonalisation.
Contributions:Â Improvements in work demands, managerial support and role clarity may reduce burnout among HCP in a rural, primary care setting
Scalable Multispecies Ion Transport in a Grid Based Surface-Electrode Trap
We present a scalable method for the control of ion crystals in a grid-based
surface electrode Paul trap and characterize it in the context of transport
operations that sort and reorder multispecies crystals. By combining co-wiring
of control electrodes at translationally symmetric locations in each grid site
with the site-wise ability to exchange the voltages applied to two special
electrodes gated by a binary input, site-dependent operations are achieved
using only a fixed number of analog voltage signals and a single digital input
per site. In two separate experimental systems containing nominally identical
grid traps, one using - crystals
and the other -, we demonstrate
this method by characterizing the conditional intra-site crystal reorder and
the conditional exchange of ions between adjacent sites on the grid. Averaged
across a multi-site region of interest, we measure sub-quanta motional
excitation in the axial in-phase and out-of-phase modes of the crystals
following these operations at exchange rates of 2.5 kHz. These conditional
transport operations display all necessary components for sorting qubits, and
could be extended to implement other conditional operations involving control
fields such as gates, initialization, and measurement.Comment: 11 pages, 7 figure
Micronutrient fortification to improve growth and health of maternally HIV-unexposed and exposed Zambian infants: a randomised controlled trial
Background: The period of complementary feeding, starting around 6 months of age, is a time of high risk for growth faltering and morbidity. Low micronutrient density of locally available foods is a common problem in low income countries. Children of HIV-infected women are especially vulnerable. Although antiretroviral prophylaxis can reduce breast milk HIV transmission in early infancy, there are no clear feeding guidelines for after 6 months. There is a need for acceptable, feasible, affordable, sustainable and safe (AFASS by WHO terminology) foods for both HIV-exposed and unexposed children after 6 months of age. Methods and Findings: We conducted in Lusaka, Zambia, a randomised double-blind trial of two locally made infant foods: porridges made of flour composed of maize, beans, bambaranuts and groundnuts. One flour contained a basal and the other a rich level of micronutrient fortification. Infants (n = 743) aged 6 months were randomised to receive either regime for 12 months. The primary outcome was stunting (length-for-age Z < -2) at age 18 months. No significant differences were seen between trial arms overall in proportion stunted at 18 months (adjusted odds ratio 0.87; 95% CI 0.50, 1.53; P = 0.63), mean length-for-age Z score, or rate of hospital referral or death. Among children of HIV-infected mothers who breastfed <6 months (53% of HIV-infected mothers), the richly-fortified porridge increased length-for-age and reduced stunting (adjusted odds ratio 0.17; 95% CI 0.04, 0.84; P = 0.03). Rich fortification improved iron status at 18 months as measured by hemoglobin, ferritin and serum transferrin receptors. Conclusions: In the whole study population, the rich micronutrient fortification did not reduce stunting or hospital referral but did improve iron status and reduce anemia. Importantly, in the infants of HIV-infected mothers who stopped breastfeeding before 6 months, the rich fortification improved linear growth. Provision of such fortified foods may benefit health of these high risk infants

Lassa Fever in Post-Conflict Sierra Leone
Background: Lassa fever (LF), an often-fatal hemorrhagic disease caused by Lassa virus (LASV), is a major public health threat in West Africa. When the violent civil conflict in Sierra Leone (1991 to 2002) ended, an international consortium assisted in restoration of the LF program at Kenema Government Hospital (KGH) in an area with the world's highest incidence of the disease. Methodology/Principal Findings Clinical and laboratory records of patients presenting to the KGH Lassa Ward in the post-conflict period were organized electronically. Recombinant antigen-based LF immunoassays were used to assess LASV antigenemia and LASV-specific antibodies in patients who met criteria for suspected LF. KGH has been reestablished as a center for LF treatment and research, with over 500 suspected cases now presenting yearly. Higher case fatality rates (CFRs) in LF patients were observed compared to studies conducted prior to the civil conflict. Different criteria for defining LF stages and differences in sensitivity of assays likely account for these differences. The highest incidence of LF in Sierra Leone was observed during the dry season. LF cases were observed in ten of Sierra Leone's thirteen districts, with numerous cases from outside the traditional endemic zone. Deaths in patients presenting with LASV antigenemia were skewed towards individuals less than 29 years of age. Women self-reporting as pregnant were significantly overrepresented among LASV antigenemic patients. The CFR of ribavirin-treated patients presenting early in acute infection was lower than in untreated subjects. Conclusions/Significance: Lassa fever remains a major public health threat in Sierra Leone. Outreach activities should expand because LF may be more widespread in Sierra Leone than previously recognized. Enhanced case finding to ensure rapid diagnosis and treatment is imperative to reduce mortality. Even with ribavirin treatment, there was a high rate of fatalities underscoring the need to develop more effective and/or supplemental treatments for LF
The Major Surface-Associated Saccharides of Klebsiella pneumoniae Contribute to Host Cell Association
Analysing the pathogenic mechanisms of a bacterium requires an understanding of the composition of the bacterial cell surface. The bacterial surface provides the first barrier against innate immune mechanisms as well as mediating attachment to cells/surfaces to resist clearance. We utilised a series of Klebsiella pneumoniae mutants in which the two major polysaccharide layers, capsule and lipopolysaccharide (LPS), were absent or truncated, to investigate the ability of these layers to protect against innate immune mechanisms and to associate with eukaryotic cells. The capsule alone was found to be essential for resistance to complement mediated killing while both capsule and LPS were involved in cell-association, albeit through different mechanisms. The capsule impeded cell-association while the LPS saccharides increased cell-association in a non-specific manner. The electrohydrodynamic characteristics of the strains suggested the differing interaction of each bacterial strain with eukaryotic cells could be partly explained by the charge density displayed by the outermost polysaccharide layer. This highlights the importance of considering not only specific adhesin:ligand interactions commonly studied in adherence assays but also the initial non-specific interactions governed largely by the electrostatic interaction forces
Trends in future health financing and coverage: future health spending and universal health coverage in 188 countries, 2016–40
Background: Achieving universal health coverage (UHC) requires health financing systems that provide prepaid pooled resources for key health services without placing undue financial stress on households. Understanding current and future trajectories of health financing is vital for progress towards UHC. We used historical health financing data for 188 countries from 1995 to 2015 to estimate future scenarios of health spending and pooled health spending through to 2040. Methods: We extracted historical data on gross domestic product (GDP) and health spending for 188 countries from 1995 to 2015, and projected annual GDP, development assistance for health, and government, out-of-pocket, and prepaid private health spending from 2015 through to 2040 as a reference scenario. These estimates were generated using an ensemble of models that varied key demographic and socioeconomic determinants. We generated better and worse alternative future scenarios based on the global distribution of historic health spending growth rates. Last, we used stochastic frontier analysis to investigate the association between pooled health resources and UHC index, a measure of a country's UHC service coverage. Finally, we estimated future UHC performance and the number of people covered under the three future scenarios. Findings: In the reference scenario, global health spending was projected to increase from US20 trillion (18 trillion to 22 trillion) in 2040. Per capita health spending was projected to increase fastest in upper-middle-income countries, at 4·2% (3·4–5·1) per year, followed by lower-middle-income countries (4·0%, 3·6–4·5) and low-income countries (2·2%, 1·7–2·8). Despite global growth, per capita health spending was projected to range from only 413 (263–668) in 2040 in low-income countries, and from 1699 (711–3423) in lower-middle-income countries. Globally, the share of health spending covered by pooled resources would range widely, from 19·8% (10·3–38·6) in Nigeria to 97·9% (96·4–98·5) in Seychelles. Historical performance on the UHC index was significantly associated with pooled resources per capita. Across the alternative scenarios, we estimate UHC reaching between 5·1 billion (4·9 billion to 5·3 billion) and 5·6 billion (5·3 billion to 5·8 billion) lives in 2030. Interpretation: We chart future scenarios for health spending and its relationship with UHC. Ensuring that all countries have sustainable pooled health resources is crucial to the achievement of UHC.
