ANTIBACTERIAL ACTIVITIES OF HONEY FROM DIFFERENT LOCATIONS IN THE TROPICAL RAIN FOREST BELT OF NIGERIA, ON SELECTED BACTERIAL ISOLATES

Honey has been used for various purposes including treatment of diseases. This study was carried out to determine antibacterial activities of honey samples obtained from different locations in the tropical Rainforest Belt of Nigeria (Abeokuta, Aiyetoro, Ajebo, and Saki) against reference bacterial isolates: Escherichia coli (E.coli) (ATCC 25922) and Staphylococcus aureus (ATCC 25923), using agar well diffusion technique. Staphylococcus aureus showed sensitivity to all honey samples used with the zone of inhibition ranging between 1.9 and 2.6mm. Escherichia coli was resistant to all concentrations of honey samples used. However, the present study did not explore the possible causative agent(s) involved in the antibacterial activity of the honey used.Â

Weed Control Efficacy and Arbuscular Mycorrhizal (AM) Colonization of Upland Rice Varieties as Affected by Population Densities

Field  experiments were  conducted in 2011 and 2012 at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta (Latitude 7 20`N and Longitude 3 23`E) in the Forest/ Savanna Transition Agro- ecological zone of South Western Nigeria  to determine the weed control efficacy and AM colonization  of upland rice varieties   at different population densities. The experiment was a 3x3 factorial arranged in a Randomized Complete Block Design (RCBD) and replicated three times. The three plant population used included 333, 333; 250, 000 and 166, 666 plants per hectare obtained by planting at 20cm x 15cm, 20cm x 20cm and 20cm x 30 cm respectively, while the three rice varieties used were ITA 150, NERICA 2 and OFADA. The results obtained from the study showed that plant population at 333, 333 plants per hectare significantly (p < 0.05) reduced weed population, number of tillers per hill and yield of rice varieties. Moreover, the local rice variety, OFADA was observed to be significantly (p < 0.05) taller than the other varieties, reduced weed biomass and consequently gave better yield advantage over the other tested varieties (ITA 150 and NERICA 2).   Panicle length and days to 50% flowering were significantly (p<0.05) longer in OFADA and NERICA 2.  Planting density did not affect AM root colonization but significant differences were observed among the rice varieties with respect to spore abundance.

Genotoxicity assessment of a pharmaceutical effluent using four bioassays

Pharmaceutical industries are among the major contributors to industrial waste. Their effluents when wrongly handled and disposed of endanger both human and environmental health. In this study, we investigated the potential genotoxicity of a pharmaceutical effluent, by using the Allium cepa, mouse- sperm morphology, bone marrow chromosome aberration (CA) and micronucleus (MN) assays. Some of the physico-chemical properties of the effluent were also determined. The A. cepa and the animal assays were respectively carried out at concentrations of 0.5, 1, 2.5, 5 and 10%; and 1, 5, 10, 25 and 50% of the effluent. There was a statistically different (p < 0.05), concentration-dependent inhibition of onion root growth and mitotic index, and induction of chromosomal aberrations in the onion and mouse CA test. Assessment of sperm shape showed that the fraction of the sperm that was abnormal in shape was significantly (p < 0.05) greater than the negative control value. MN analysis showed a dose-dependent induction of micronucleated polychromatic erythrocytes across the treatment groups. These observations were provoked by the toxic and genotoxic constituents present in test samples. The tested pharmaceutical effluent is a potentially genotoxic agent and germ cell mutagen, and may induce adverse health effects in exposed individuals

The burden and risks of pediatric pneumonia in Nigeria: A desk‐based review of existing literature and data

Background: Pneumonia is a leading killer of children under‐5 years, with a high burden in Nigeria. We aimed to quantify the regional burden and risks of pediatric pneumonia in Nigeria, and specifically the states of Lagos and Jigawa. / Methods: We conducted a scoping literature search for studies of pneumonia morbidity and mortality in under‐5 children in Nigeria from 10th December 2018 to 26th April 2019, searching: Cochrane, PubMed, and Web of Science. We included grey literature from stakeholders' websites and information shared by organizations working in Nigeria. We conducted multivariable logistic regression using the 2016 to 2017 Multiple Cluster Indicators Survey data set to explore factors associated with pneumonia. Descriptive analyses of datasets from 2010 to 2019 was done to estimate trends in mortality, morbidity, and vaccination coverage. / Results: We identified 25 relevant papers (10 from Jigawa, 8 from Lagos, and 14 national data). None included data on pneumonia or acute respiratory tract infection burden in the health system, inpatient case‐fatality rates, severity, or age‐specific pneumonia mortality rates at state level. Secondary data analysis found that no household or caregiver socioeconomic indicators were consistently associated with self‐reported symptoms of cough and/or difficulty breathing, and seasonality was inconsistently associated, dependant on region. / Conclusion: There is a clear evidence gap around the burden of pediatric pneumonia in Nigeria, and challenges with the interpretation of existing household survey data. Improved survey approaches are needed to understand the risks of pediatric pneumonia in Nigeria, alongside the need for investment in reliable routine data systems to provide data on the clinical pneumonia burden in Nigeria

Health system challenges for improved childhood pneumonia case management in Lagos and Jigawa, Nigeria

Background: Case fatality rates for childhood pneumonia in Nigeria remain high. There is a clear need for improved case management of pneumonia, through the sustainable implementation of the Integrated Management of Childhood Illnesses (IMCI) diagnostic and treatment algorithms. We explored barriers and opportunities for improved case management of childhood pneumonia in Lagos and Jigawa states, Nigeria. / Methods: A mixed‐method analysis was conducted to assess the current health system capacity to deliver quality care. This was done through audits of 16 facilities in Jigawa and 14 facilities in Lagos, questionnaires (n = 164) and 13 focus group discussions with providers. Field observations provided context for data analysis and triangulation. / Results: There were more private providers in Lagos (4/8 secondary facilities) and more government providers in Jigawa (4/8 primary, 3/3 secondary, and 1/1 tertiary facilities). Oxygen and pulse oximeters were available in two of three in Jigawa and six of eight in Lagos of the sampled secondary care facilities. None of the eight primary facilities surveyed in Jigawa had oxygen or pulse oximetry available while in Lagos two of three primary facilities had oxygen and one of three had pulse oximeters. Other IMCI and emergency equipment were also lacking including respiratory rate timers, particularly in Jigawa state. Health care providers scored poorly on knowledge of IMCI, though previous IMCI training was associated with better knowledge. Key enabling factors in delivering pediatric care highlighted by health care providers included accountability procedures and feedback loops, the provision of free medication for children, and philanthropic acts. Common barriers to provide care included the burden of out‐of‐pocket payments, challenges in effective communication with caregivers, delayed presentation, and lack of clear diagnosis, and case management guidelines. / Conclusion: There is an urgent need to improve how the prevention and treatment of pediatric pneumonia is directed in both Lagos and Jigawa. Priority areas for reducing pediatric pneumonia burden are training and mentoring of health care providers, community health education, and introduction of oximeters and oxygen supply

Neuro-feedback intervention efficacy for treating children with Autism Spectrum Disorder

This study explored practitioners perceptions of a neuro-feedback intervention in treating children with Autism Spectrum Disorder’s (ASD). Informants were a convenience sample of ten South African neuro-feedback practitioners registered with the Health Professions Council of South Africa (HPCSA). The data on their views on neuro-feedback treatment efficacy, with children with ASD, were collected by means of semi-structured in-depth interviews. Thematic analysis of the data suggest practitioners to perceive neuro-feedback treatment to enhance the social, mood, behaviour, academic life, and family functioning of children with ASD. Additionally, the practitioners perceived neuro-feedback treatment to assist in reducing anxiety among children with ASD

The first-line antituberculosis drugs, and their fixed-dose combination induced abnormal sperm morphology and histological lesions in the testicular cells of male mice

Rifampicin (RIF), Isoniazid (INH), Ethambutol (EMB), Pyrazinamide (PZA), and/or their fixed-dose combination (FDC) are extensively prescribed in the cure of Tuberculosis (TB) globally. In spite of the beneficial effect, these drugs are capable of inducing cellular toxicity. Existing information on the genotoxic effects of the first-line anti-TB drugs is limited and contentious. Herein, we evaluated the reproductive genotoxicity of RIF, INH, EMB, PZA, and their FDC utilizing the mouse sperm morphology assay. Histological examination of the testes of exposed mice was also performed. Male Swiss albino mice (11–13 weeks old) were intraperitoneally exposed for 5 consecutive days to each of the anti-TB drugs at four different doses of 6.25, 12.5, 25, and 50 mg/kg bw of PZA; 2.5, 5.0, 10, and 20 mg/kg bw of RIF; 1.25, 2.5, 5.0 and 10 mg/kg bw of INH; 3.75, 7.5, 15 and 30 mg/kg bw of EMB; and 7, 14, 28 and 56 mg/kg bw of FDC corresponding respectively to ×0.25, ×0.5, ×1 and ×2.0 of the standard daily dose. In comparison with the negative control (normal saline), there was no significant difference in the testicular weight and organo-somatic index of exposed mice. There was an increase (p &gt; 0.05) in the frequency of abnormal spermatozoa at most of the tested doses of each drug and a dose-dependent decrease with the FDC. Each of the anti-TB drugs except the FDC induced pathological lesions in the testes. These findings suggest that the individual first-line anti-TB drug unlike the FDC has the potential to provoke testicular anomalies in male mice
