DOES WORKING CAPITAL MANAGEMENT AFFECT THE PROFITABILITY OF CONSUMER GOODS MANUFACTURING FIRMS IN NIGERIA?
The study examined the effect of working capital management on profitability of consumer goods manufacturing firms in Nigeria between the periods 2009 to 2018. The study adopted ex-post-facto design to generate data from the audited financial statements of the selected companies. The population of the study comprised 24 listed consumer goods manufacturing companies, out of which 10 were purposively selected based on the availability of data. The surrogates for independent variables were Account Payable Period (APP), Account Receivable Period (ARP), Inventory Turnover Period (INVTP), Cash Conversion Cycle (CCC) and Sales Growth (SG) as a control variable while the proxy for profitability was Return on Asset (ROA). Descriptive and inferential statistics coupled with multiple regressions were adopted to analyze the data. The Random Effects Generalized Least Square showed that ARP, INVTP, CCC had a negative and significant relationship with ROA while APP, SG had a positive and insignificant relationship with ROA. The study concluded that timely collection of debts and shorter inventory turnover period with cash conversion cycle enhance profitability of consumer goods manufacturing companies. Hence, the study suggested that the management of the companies should implement efficient working capital management for improved profitability.
 
COMPARATIVE EVALUATION OF GENOTYPING AND CULTURE-BASED TECHNIQUES FOR FUNGAL KERATITIS DETECTION
The study aims to compare the direct polymerase chain reaction with microbial culture for the detection and fungal pathogens in infectious keratitis. A total of 81 corneal ulcers were culture and analyzed prospectively. PCR was performed with all corneal scrapping with fungal and bacteria specific primers. PCR products were analysed and compared with the culture results using standard methods. Of the 81 samples, 80 were positive by PCR, 51 for fungi and 29 for bacteria. Out of 51 PCR positive samples, 22 samples were culture positive and 29 were culture negative. The majority of PCR genotyped samples matched the positive culture results. The positive detection rate of 80/81 (98.8%) with high suspicion of fungal keratitis and positive detection rate of direct PCR 50/51(98.0%) were observed. The sensitivities for the diagnosis of fungal keratitis with direct PCR and culture were 98.0% (50/51) and 43.1% (22/51) (p< 0.001) whereas the specificities were 100.0% (2/2) and 100.0% (1/1) respectively. The time required to complete the direct PCR was only 3 hours. The direct PCR assay is a rapid diagnostic technique with high sensitivity and specificity for infectious keratitis and it is expected to have impact on the diagnosis and treatment of infectious keratitis.

COMPARATIVE EVALUATION OF GENOTYPING AND CULTURE-BASED TECHNIQUES FOR FUNGAL KERATITIS DETECTION
The study aims to compare the direct polymerase chain reaction with microbial culture for the detection and fungal pathogens in
infectious keratitis. A total of 81 corneal ulcers were culture and analyzed prospectively. PCR was performed with all corneal
scrapping with fungal and bacteria specific primers. PCR products were analysed and compared with the culture results using
standard methods. Of the 81 samples, 80 were positive by PCR, 51 for fungi and 29 for bacteria. Out of 51 PCR positive samples,
22 samples were culture positive and 29 were culture negative. The majority of PCR genotyped samples matched the positive
culture results. The positive detection rate of 80/81 (98.8%) with high suspicion of fungal keratitis and positive detection rate of
direct PCR 50/51(98.0%) were observed. The sensitivities for the diagnosis of fungal keratitis with direct PCR and culture were
98.0% (50/51) and 43.1% (22/51) (p< 0.001) whereas the specificities were 100.0% (2/2) and 100.0% (1/1) respectively. The time
required to complete the direct PCR was only 3 hours. The direct PCR assay is a rapid diagnostic technique with high sensitivity
and specificity for infectious keratitis and it is expected to have impact on the diagnosis and treatment of infectious keratitis

In silico evaluation of inhibitors of Plasmodium falciparumAP2âI transcription factor
Recent treatment failures observed for Artemisininâbased combination therapy (ACT) have raised
concerns about the efficacy of the frontâline drug to treat malaria and the need to develop a new
antimalarial drug regimen. Plasmodium falciparum Apicomplexan Apetala 2 Invasion (PfAP2âI)
transcription factor (TF) is a protein that regulates the expression of a subset of gene families involved
in Plasmodium falciparum red blood cell (RBC) invasion. Inhibiting PfAP2âI TF with small molecules
represents a potential new antimalarial therapeutic target to combat drug resistance, which is the aim of this study. The 3D model structure of PfAP2âI was predicted ab initio using ITASSER and ROBETTA
prediction tools and was validated using Errat and Procheck from the Save server 6.0. Computed Atlas of
Surface Topography of proteins (CASTp) 3.0 and ConCavity were used to predict the active sites of
the PfAP2âI 3D7 modeled structure. Pharmacophore modeling of the control ligand (3W7 from COACH
server) and modeled 3D structure of PfAP2âI was carried out using the Pharmit server to obtain several
compounds for docking analysis. Chimera software was used to remove the complexed ligands, and the
modeled protein structure was defined as a receptor. Virtual screening and postâscreening studies were
conducted using AutoDock vina and LigPlot. The designed ligandsâ toxicity predictions and in silico druglikeness
were performed using the Swiss ADME predictor and OSIRIS Property Explorer. The modeled
protein from the ROBETTA prediction tool was prioritized based on structure validation results of 96.827
for ERRAT and 90.2% of the amino acid residues in the most favored region for the Ramachandran plot.
A total of 8656 compounds obtained from six (6) databases on the Pharmit server were used to prepare
the ligand library and screened against the prepared 3D model structure of PfAP2âI, considering the
active sites predicted from CASTp and ConCavity. Six (6) best hits were selected based on the binding
affinity to the active site PfAP2âI and were considered for postâscreening analyses. The six compounds
exhibited dock score values (between â9.9 to â10.2 kcal/mol), having lower binding energies than the
standard drug â Chloroquine (â5.10 kcal/mol). The best dock score was compound ZINC97139187 (â10.2
kcal/mol). For the ADMET properties, compound ZINC97139187 had the highest drug score of 0.63,
followed by compound 154861216 with a drug score of 0.58 (both higher than that of the standard drug
â chloroquine of 0.25). The good, estimated binding energies and drug score values observed for
compound ZINC97139187 and compound 154861216 suggest that they can be considered
possible PfAP2âI inhibitors. Further preâclinical experimental validations should be carried out to
ascertain the efficacy of these predicted best hit
In Silico Evaluation of Inhibitors of Plasmodium Falciparum AP2-I Transcription Factor and Plasmodium Falciparum Bromodomain Protein 1
Recent treatment failures observed for Artemisinin-based combination therapy (ACT) have raised concerns about the efficacy of the front-line drug to treat
malaria and the need to develop a new antimalarial drug regimen. Plasmodium falciparum Apicomplexan Apetala 2 Invasion (PfAP2-I) transcription factor
(TF) is a protein that regulates the expression of a subset of gene families involved in Plasmodium falciparum red blood cell (RBC) invasion. PfAP2-I
associates with several chromatin proteins, including the Plasmodium falciparum bromodomain protein 1 (PfBDP1) and that complex formation is associated
with transcriptional regulation. Inhibiting PfAP2-I TF and PfBDP1 with small molecules represents a potential new antimalarial therapeutic target to combat
drug resistance, which this study aims to achieve
Patient characteristics associated with COVID-19 positivity and fatality in Nigeria: retrospective cohort study
Objective: Despite the increasing disease burden, there is
a dearth of context-specific evidence on the risk factors for
COVID-19 positivity and subsequent death in Nigeria. Thus,
the study objective was to identify context-specific factors
associated with testing positive for COVID-19 and fatality
in Nigeria.
Design Retrospective cohort study.
Setting: COVID-19 surveillance and laboratory centres in
36 states and the Federal Capital Territory reporting data to
the Nigeria Centre for Disease Control.
Participants: Individuals who were investigated for SARSCoV-2 using real-time PCR testing during the study period
27 Februaryâ8 June 2020.
Methods: COVID-19 positivity and subsequent mortality.
Multivariable logistic regression analyses were performed
to identify factors independently associated with both
outcome variables, and findings are presented as adjusted
ORs (aORs) and 95% CIs.
Results: A total of 36 496 patients were tested for
COVID-19, with 10 517 confirmed cases. Of 3215
confirmed cases with available clinical outcomes, 295
died. Factors independently associated with COVID-19
positivity were older age (p value for trend<0.0001), male
sex (aOR 1.11, 95%CI 1.04 to 1.18) and the following
presenting symptoms: cough (aOR 1.23, 95% CI 1.13 to
1.32), fever (aOR 1.45, 95% CI 1.45 to 1.71), loss of smell
(aOR 7.78, 95% CI 5.19 to 11.66) and loss of taste (aOR
2.50, 95% CI 1.60 to 3.90). An increased risk of mortality
following COVID-19 was observed in those aged â„51
years, patients in farming occupation (aOR 7.56, 95% CI
1.70 to 33.53) and those presenting with cough (aOR 2.06,
95% CI 1.41 to 3.01), breathing difficulties (aOR 5.68, 95%
CI 3.77 to 8.58) and vomiting (aOR 2.54, 95% CI 1.33 to
4.84).
Conclusion: The significant risk factors associated with
COVID-19 positivity and subsequent mortality in the
Nigerian population are similar to those reported in studies
from other countries and should guide clinical decisions for
COVID-19 testing and specialist care referrals
