International Journal of Environmental Health Research. 00:1–18., Number 00: Taylor & Francis AbstractWebsite

Poorly maintained living conditions and infrastructure are the banes of Nigerian prisons. The study investigated its environmental conditions and the prevalent diseases among inmates. The descriptive, cross-sectional study enrolled 420-inmates through a multistage sampling technique. Pre-tested instruments were administered and results presented with descriptive and logistic regression to identify predictors of toilet-cleaning and handwashing practices at P∝0.05. The mean(±SD) age and modal inmates/cell were 30±7.2 years and 36. Most inmates were males (97%), await-trial (79%) and lives in overcrowded cells (58%). Sixty-nine percent of free-cells has pour-flush toilets and 36% waits for 2–5 minutes before accessing toilets. Fifty-three percent of inmates clean latrines with water and soap, 71% burn solid waste while handwashing period-prevalence was 36%. Religion, toilet-cleaning, and education were predictors of handwashing while types of toilets and access predict toilet-cleaning behaviour. Malaria (81.1%) and scabies (7.3%) were endemic. The prison rehabilitation shall satisfy basic life needs and promote prisoners' health.

Eziyi, J, Elusiya J, Olateju O, Amusa Y, Akinpelu V, Eziyi A.  2021.  Tongue Entrapment in an Aluminium Milk Can: An Unusual Cause of Tongue Injury, 2021/09/07. Abstract

Peri-oral injuries are common findings in paediatric patients; however, tongue injury following entrapment in bottles and cans is rare and has not been reported in our locality. A case of a 9- year old previously healthy female child who got her tongue tightly entrapped in an half opened aluminium milk can while in school is hereby presented. This case highlights the result of careless and often dangerous play and misadventures of children and the challenge of management. It calls for vigilance and close supervision of children by caregivers at home and at school. Early presentation, immediate intervention and treatment can prevent grave consequences.

This study fabricated and characterized a self-sustaining hydrogenous content clay-polyethylene composite opted for ionizing radiation shielding. Composites designated A–G were fabricated each containing 0–30 wt% of recycled low density polyethylene (LDPE), respectively. To know the effects of the incorporated LDPE on the morphology, microstructural, compressive strength, thermal property and displacement effect on the vital elements were studied using scanning electron microscopy (SEM), X-ray diffractometry (XRD), universal mechanical testing machine, differential thermal analysis (DTA), Rutherford backscattering (RBS) technique and particle induced X-ray emission (PIXE), respectively. The bulk densities of the clay composites ranged between 1.341 and 2.030 g/cm3. The samples’ XRD analysis revealed similar patterns, with a sharp and prominent peak at angle 2θ equals ~26.11°, which matched with card number 16-0606 of the Joint Committee on Powder Diffraction Standards (JCPDS) that represents Aluminum Silicate Hydroxide (Al2Si2O5(OH)4), a basic formula for Kaolin clay. The compressive strength ranged between 2.52 and 5.53 MPa. The ratio of Si to Al in each composite is about 1:1. The dehydroxylation temperature for samples ranged between 443.23 °C and 555.23 °C.

Abstract

The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables-COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60-3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20-0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

Ameye, S, Ikoko M, Awoleye M, Eziyi J.  2021.  Evaluation of the performance of machine learning algorithms applied to voice parameters in prioritizing candidate for office laryngoscopy: Automated triaging in focus, 2021/07/30. 11:169-175. Abstract

Background: We examined the performance of different Machine Learning Algorithms while also comparing two methods of voice assessment to look at the workability of automating triage of patient that will need prompt office laryngoscopy. Methods: We recruited consecutive adult subjects excluding those with a history of being regular singers or choristers in the past one year and those with the previous history of laryngeal trauma. We then carried out the perceptual voice assessments on the GRBAS Scale and also obtained the basic acoustic parameters of the voice samples. Laryngeal examinations with 70-degree Hopkins’ Rod were then carried out by another examiner for all the participants to identify gross laryngeal changes or lesions. We then evaluated each machine learning algorithm comparing the perceptual and acoustic parameters in determining how well each algorithm predicts the presence of those categorized with having lesion or not by the laryngeal examination. Results: One hundred and twenty respondents were analyzed out of which 89(74.2%) were females. The mean age was 46.5 ± 9.2 years. The perceptual evaluation generally outperformed the acoustic evaluation. Also, the Naïve Bayes Classifier (NBC) outperformed other algorithms with a F1 score of 0.55 followed by Artificial Neural Network (ANN) with the score of 0.53. However, the ANN outperformed the other with regards to the Area-under-the-curve (AUC). Conclusion: When these metrics are taken together, the ANN still remains the best algorithm for this dataset. We are however cognisance of the needed improvement to the various aspects of this work including a larger dataset more scientific sampling.

Abstract

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

Introduction:Neuropsychiatric events are often associated with viral pandemics. The unexpected turn of events the world over since the onset of the coronavirus pandemic may serve as stressors which can trigger or worsen mental disorders particularly psychosis. There is little or no reports about acute psychosis on the background of this current global pandemic particularly in the African context. The aim of this article describes a case series of acute schizophrenia-like disorder with COVID-19 related psychotic themes in the context of the current pandemic.
Materials and methods:
We present a case series of 2 patients with first episode psychotic illnesses during the COVID-19 pandemic. Both patients presented at the mental health outpatient clinic of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria.
Results:
Two patients with no previous history of mental illness presented with COVID-19 delusional themes and odd behaviours. Mental state examination revealed abnormalities in behaviour, thought system, perception and cognition. ICD10 diagnosis of Acute and Transient Psychotic disorder was made in both patients. There were no abnormal physical health findings and symptoms resolved with the use of antipsychotics.
Conclusion:
Information on the COVID-19 pandemic may influence the content of psychotic experiences among the general population. A high index of suspicion and acute services are important to ensure prompt intervention and promotion of community mental health. Clinicians need to be well informed to be able to identify what deviates from the norm, and to be able to provide prompt intervention.

Graphene oxide (GO) acts as an insulator but when reduced to reduced graphene oxide (RGO), it has high heat storage capacity. This can result in lowering the phase change temperature when embedded in a material such as expanded polystyrene (EPS), thus making it a good heat-resistance material. In this study, the thermal and the mechanical effects of GO and RGOs over EPS were analysed. GO was synthesized using modified Hummer’s method, while the reduction process was taken through different routes using three different reductants: hydrazine (RGO-HZ), ascorbic acid (RGO-AA) and the extract of Amaranthus hybridus (RGO-AH). The same content of graphite and its derivatives were separately and chemically bonded together with EPS forming composites (i.e., graphite composite, GO composite, RGO-HZ composite, RGO-AA composite and RGO-AH composite) and cast on a mould at room temperature to form a dog-bone shape. Fourier transform infrared spectroscopy, differential thermal analysis, scanning electron microscopy and mechanical tests were conducted on ordinary EPS and on each of the composite samples. The results showed a significant enhancement of thermal and mechanical properties of the composites over ordinary EPS.
