Significant Bacteriuria Among Asymptomatic Antenatal Clinic Attendees In Ibadan, Nigeria
Untreated asymptomatic bacteriuria can lead to urinary tract infection (UTI) in pregnancy with devastating maternal and neonatal effects such as prematurity and low birth weight, higher fetal mortality rates and significant maternal morbidity. We carried out a two year (April 2007 to March 2009) cross-sectional epidemiological study to determine the prevalence of significant bacteriuria among asymptomatic antenatal clinic attendees at two antenatal clinics (ANCs) in University College Hospital and Adeoyo Maternity Hospital, both in Ibadan, Nigeria
Clients' reasons for prenatal ultrasonography in Ibadan, South West of Nigeria
<p>Abstract</p> <p>Background</p> <p>Prenatal ultrasonography has remained a universal tool but little is known especially from developing countries on clients' reasons for desiring it. Then aim was to determine the reasons why pregnant women will desire a prenatal ultrasound.</p> <p>Methods</p> <p>It was a cross-sectional survey of consecutive 222 women at 2 different ultrasonography facilities in Ibadan, South-west Nigeria.</p> <p>Results</p> <p>The mean age of the respondents was 30.1 ± 4.5 years. The commonest reason for requesting for prenatal ultrasound scans was to check for fetal viability in 144 women (64.7%) of the respondents, followed by fetal gender determination in 50 women (22.6%. Other reasons were to check for number of fetuses, fetal age and placental location. Factors such as younger age, artisans profession and low level of education significantly influenced the decision to check for fetal viability on bivariate analysis but all were not significant on multivariate analysis. Concerning fetal gender determination, older age, Christianity, occupation and gravidity were significant on bivariate analysis, however, only gravidity and occupation remained significant independent predictor on logistic regression model. Women with less than 3 previous pregnancies were about 4 times more likely to request for fetal sex determination than women with more than 3 previous pregnancies, (OR 3.8 95%CI 1.52 – 9.44).

Emergence and spread of two SARS-CoV-2 variants of interest in Nigeria.
Identifying the dissemination patterns and impacts of a virus of economic or health importance during a pandemic is crucial, as it informs the public on policies for containment in order to reduce the spread of the virus. In this study, we integrated genomic and travel data to investigate the emergence and spread of the SARS-CoV-2 B.1.1.318 and B.1.525 (Eta) variants of interest in Nigeria and the wider Africa region. By integrating travel data and phylogeographic reconstructions, we find that these two variants that arose during the second wave in Nigeria emerged from within Africa, with the B.1.525 from Nigeria, and then spread to other parts of the world. Data from this study show how regional connectivity of Nigeria drove the spread of these variants of interest to surrounding countries and those connected by air-traffic. Our findings demonstrate the power of genomic analysis when combined with mobility and epidemiological data to identify the drivers of transmission, as bidirectional transmission within and between African nations are grossly underestimated as seen in our import risk index estimates
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.
Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
Perceived Impact of Personality Traits on the Academic Performance of Students in Biology
The study examined the perceived impact of personality traits on the academic performance of biology students in Makurdi, a local government area of Benue State, Nigeria. Three research questions were raised and two hypotheses were also formulated and tested. The research design adopted for this study was a descriptive survey design. The study sample comprises 384 students who were randomly selected from the total population of 9,748 students of the 20 government secondary schools in Makurdi Local Government Area of Benue State, Nigeria. The instruments used for data collection in this study were the Five-Factor Inventory Questionnaire (FFIQ) for personality traits and “The Biology Performance Test (BPT)” for academic performance. The data were analyzed using mean and standard deviation to answer the research questions, while ANOVA statistics and t-tests were used to test the hypotheses at a .05 significance level. The findings revealed that there was no significant mean difference in the five personality traits of students and the personality traits of Biology students had no significant relationship with their performance in the subject. Also, there was no significant difference in the mean performance of students in each of the five personality traits based on gender. The findings further revealed no significant difference in students’ personality traits according to gender and no significant difference in the performance of students who were offered biology according to gender. This study recommends that Special attention be paid to improving the performance of students in Biology in Makurdi to strike an association between the traits. Also, male and female students should be given equal opportunities in biology since there is no gender difference in their personality traits and academic performance
Prevalence of Hypertension at Antenatal Booking and Delivery in Ibadan
Context: Hypertension is the second commonest medical condition in pregnancy and it occurs in up to 10% of all pregnancies. It is responsible for several cardiovascular events and accounts for about 12% of all maternal deaths, which is about 1500 per 100, 000 livebirths in Nigeria.
Objectives: We assessed the prevalence of hypertension at antenatal booking and delivery among pregnant patients at the University College Hospital, Ibadan, Nigeria in other to evolve a special management plan for the control of this disease among them.
Methods: Pregnant subjects attending the antenatal clinic of the University College Hospital, Ibadan were recruited consecutively into the study. They had repeated blood pressure measurements and were followed up from antenatal clinic registration till delivery.
Results: Four hundred and nine pregnant subjects were examined and recruited into the study at booking, but only 187 of them completed the study and delivered at UCH. The frequency of hypertension at booking was 9.8%, rising to 26.2% at delivery, a statistically significant difference (χ2 = 27.25; p < 0.001). The mean SBP (127.1 ± 19.9mmHg) and DBP (80.5 ± 13.0mmHg) after delivery among the subjects were significantly higher than at booking (SBP, 114.2 ± 2.1mmHg & DBP, 73.4 ± 24mmHg; p < 0.001)
Conclusion: Prevalence of hypertension as well as the mean SBP and DBP were significantly higher post partum than at booking among the subjects. Previous personal and family history of hypertension were strong determinants of hypertension in pregnancy in them. There was no correlation between parity and level of blood pressure.
