Abstract:

Background: Much controversies have been associated with the pathogenicity of Mycoplasma hominis but little has been done to unravel the mystery behind the different views. This study aimed at investigating the genetic variants abounding within M. hominis and the distribution of the virulent genes among the variants.

Methodology: Twenty (20) M. hominis isolates from high vaginal swabs of women (11 from pregnant women and 9 from women presenting with infertility) attending the Obstetrics and Gynaecology clinics of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria, were sequenced using 16S rRNA universal gene target for the purpose of phylogenetic analysis and epidemiological typing. The isolates were also screened for the presence of M. hominis variable adherence antigen (vaa) and p120 virulent genes using primer constructs from the respective genes in a conventional PCR protocol.

Abstract:

Background: Dermatophytosis (ringworm) is a zoonotic fungal skin infection caused predominantly by Microsporum canis, Microsporum gypseum and Trichophyton spp. It is highly transmissible and, while normally self-limiting, could be problematic due to its potential to cause disease in certain human populations. The occurrence and associated risk factors of dermatophytoses in dogs presented at three veterinary clinics in Osogbo, and Ilorin, Nigeria between July and November 2019 were investigated in this study.

Methodology: This was a descriptive cross-sectional study of 325 dogs with lesions suggestive of dermato- phytosis, selected by simple random sampling from three veterinary clinics in Osogbo and Ilorin, purposively selected for the study due to high patronage of the veterinary hospitals by dog owners. Using conventional mycological sampling techniques, plucked hairs and skin scrapings were obtained the dogs. The samples were emulsified in 10% potassium hydroxide, examined microscopically for fungal elements and cultured using standard mycological procedures. Information on dog demographic characteristics and risk factors for dermatophytosis were collected using structured questionnaire. The association between risk factors and demographic variables with the occurrence of dermatophytoses was determined using Chi-square test (with Odds ratio and 95% confidence interval) and p value < 0.05 was considered statistically significant.

Abstract:

Background: Shellfishes are susceptible to a wide variety of bacterial pathogens, most of which are capable of causing disease in humans but are considered to be saprophytic in nature. Bacteriological diversity of shellfishes depends on the fishing grounds, habitats and environmental factors around them. This study assessed the bacteria associated with shellfishes, Pachycheles pubescens (crab) and Nucella lapillus (dog whelk) harvested from mesotidal estuarine ecosystem.

Methodology: The bacteriological assessment of crab (Pachycheles pubescens) and dog whelk (Nucella lapillus) harvested from Okwano Obolo estuary in Eastern Obolo local government area (LGA), Akwa Ibom was evaluated. The density of heterotrophic and potential pathogens was determined using standard analytical procedures. The pure bacterial isolates were grouped into recognizable taxonomic units and characterized to their generic level.

Abstract:

Malaria treatment failure is the inability to clear parasitaemia after antimalarial drug administration. There are reports of treatment failure with artemisinin-based combination therapy (ACT) in Nigeria but few reported among children. We report three paediatric cases of treatment failure with ACT admitted at a private tertiary hospital in Nigeria in early 2022. All three were ‘under-fives’ admitted for open-heart surgery, major flame burns, and cerebral malaria respectively. They had symptomatic Plasmodium falciparum infection but one had mixed P. falciparum and Plasmodium vivax infections. Cases 1 and 2 were initially given oral artemether-lumefantrine while case 3 received intravenous artesunate. Despite appropriate antimalarial drug compliance, all the 3 still had fever with heavy parasitaemia. They subsequently received intravenous quinine, with improvement within the first 24 hours of therapy, and no longer had fever at the fourth week of follow-up. Although ACT resistance was not established, poor drug quality may have contributed to treatment failure. There is a need for pharmacovigilance of anti-malarial in Nigeria.

Abstract:

Hepatocellular carcinoma (HCC) is the twelfth most common cancer and the fifth leading cause of worldwide cancerrelated death. Chronic hepatitis B infection, caused by the hepatitis B virus (HBV) and exposure to aflatoxins is fundamental in the formation of HCC in developing countries. This review of scientific publications aims to establish the detrimental effects of aflatoxin-contaminated foods and highlights the correlation between aflatoxin and hepatitis B viral-associated hepatocellular carcinoma. Research has shown a significant increase in the occurrence of HCC in HBV-infected individuals exposed to fungal toxins. HBV demonstrates the ability to integrate and bind to p53 protein in the host DNA and propagate hepatocyte vulnerability through carcinogenic aflatoxin B1 (AFB1) damage. Although there has been clear evidence about the synergistic interaction of exposure to AFB1 and HBV infection in the induction of HCC, other literature has shown otherwise, mainly because incomplete and vague findings and hypotheses were made in regions where AFB1 and HBV pose a public health risk. Vaccination against hepatitis B and measures such as robust food safety systems to avoid hepatotoxicity and hepatocellular carcinogenesis induced by AFB1 is the most effective methods in the prevention of HCC induced by HBV and AFB1.

Abstract:

 Background: The extraction step of the viral material of the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) influences the quality of reverse transcriptase-polymerase chain reaction (RT-PCR) results in diagnosis of coronavirus disease 2019 (COVID-19). The purpose of this cross-sectional study was to evaluate the diagnostic performance of the automated extraction system “KingFisher Flex Purification System 96 (ThermoFisher)” compared to the manual method with the “QIAamp Viral RNA Mini Kit (Qiagen)”.

Methodology: From October to December 2020, comparative diagnostic evaluation of two methods of SARSCoV-2 RNA extraction methods was conducted on 159 fresh and 120 frozen nasopharyngeal and oropharyngeal specimens collected from travellers and suspected cases or contacts of COVID-19 patients in Burkina Faso. The FastPlexTM Triplex 1-Step COVID 19 Detection Kit (RT-PCR, RNA extraction free) (Precigenome LLC) was used to amplify on the same PCR plate, RNA extracts from manual QIAamp Viral RNA Mini Kit and automated KingFisher Flex Purification System 96 (ThermoFisher) using the QuantStudio5 thermal cycler (Applied Biosystems). Analysis of the diagnostic performance of the SARS-CoV-2 RT-PCR assay following RNA extraction by the two methods was done using an online OpenEpi software.

Abstract:

 Background: To control the spread of coronavirus disease-19 (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), it is necessary to adequately identify and isolate infectious patients particularly at the work place. Real time polymerase chain reaction (RT-PCR) assay is the recommended confirmatory method for the diagnosis of SARS-CoV-2 infection. The aim of this study was to determine the prevalence of SARSCoV-2 infection in Burkina Faso and to use the initial cycle threshold (Ct) values of RT-PCR as a tool to monitor the dynamics of the viral load.

Methodology: Between September 2021 and February 2022, oropharyngeal and/or nasopharyngeal swab samples of consecutively selected COVID-19 symptomatic and apparently healthy workers from the Wahgnion mining site in the South-western Burkina Faso who consented to the study were collected according to the two weeks shift program and tested for SARS-CoV-2 using RT-PCR assay. Patients positive for the virus were followed-up weekly until tests were negative. Association of the initial RT-PCR Ct values with disease duration was assessed by adjusted linear regression approach. Two-sided p value < 0.05 was considered statistically significant.

 Abstract:

 Background: With the use of highly active antiretroviral therapy (HAART), life expectancy of HIV-infected persons had increased and the disease is now managed as a chronic one, but the quality of life (QOL) of the patients is now a concern. Social support enhances QOL of patients with chronic illnesses. However, no study has been done to determine the QOL of people living with HIV and AIDS (PLWHA) in our environment. This study therefore assessed the QOL of PLWHA attending antiretroviral therapy (ART) clinic of Irrua Specialist Teaching Hospital (ISTH), Edo State of Nigeria

Methodology: A descriptive cross-sectional study design was used. Two hundred and thirty PLWHA attending the ART clinic of ISTH, Irrua, Edo State, Nigeria, were systematically selected for the study. A structured questionnaire was interviewer-administered to collect data on sociodemographic and clinical profiles of selected participants, and the WHOQOL-HIV BREF questionnaire was used to collect data the QOL of each participant. Data were analyzed with IBM SPSS version 20.0. Continue reading “Quality of life of people living with HIV and AIDS attending Irrua Specialist Teaching Hospital, Edo State, Nigeria”
