Application of ICT and Electronic Technology in Election Management: Challenges in Rural Areas in South-Eastern Nigeria
This paper has presented the applications of Information Communication Technology and election management. The study has reviewed several challenges and bottleneck encountered in the electoral democratic system in Nigeria election. During the study, the use of electronic technology adoption in the electoral process has actually reduced human involvement in election process; this is due to irregularities and incessant increase in violence among electorates, party agents and other stakeholders. The relevance of this paper is to address the integration of ICT as well as electronic digital devices in carryout electrons in Nigeria. The research was conducted in the rural areas of the South-Eastern Nigeria States, it was discovered that about 60% of the respondent stated that the use of electronic technology in the deployment to rural areas has inadequate trained personnel in effective handling of the gadgets, issues on the use of card reader malfunctioning was also sported out. It was recommended that the electoral bodies should sensitized, make adequate available of electronic devices for efficient and effective election management in Nigeria
The accuracy of haemoglobin A1c as a screening and diagnostic test for gestational diabetes: a systematic review and meta-analysis of test accuracy studies
PURPOSE OF REVIEW: Gestational diabetes mellitus (GDM) is associated with adverse pregnancy complications. Accurate screening and diagnosis of gestational diabetes are critical to treatment, and in a pandemic scenario like coronavirus disease 2019 needing a simple test that minimises prolonged hospital stay. We undertook a meta-analysis on the screening and diagnostic accuracy of the haemoglobin A1c (HbA1c) test in women with and without risk factors for gestational diabetes. RECENT FINDINGS: Unlike the oral glucose tolerance test, the HbA1c test is simple, quick and more acceptable. There is a growing body of evidence on the accuracy of HbA1c as a screening and diagnostic test for GDM. We searched Medline, Embase and Cochrane Library and selected relevant studies. Accuracy data for different thresholds within the final 23 included studies (16 921 women) were pooled using a multiple thresholds model. Summary accuracy indices were estimated by selecting an optimal threshold that optimises either sensitivity or specificity according to different scenarios. SUMMARY: HbA1c is more useful as a specific test at a cut-off of 5.7% (39 mmol/mol) with a false positive rate of 10%, but should be supplemented by a more sensitive test to detect women with GDM
Blood biochemistry and haematology of weaner rabbits fed sun-dried, ensiled, and fermented cassava peel-based diets
Twenty-four New Zealand white × Chinchilla weaner bucks, aged between 7 and 8 weeks and averaging 0.9 kg in weight, were divided into four groups of six each and used in a 12-week feeding trial to evaluate the blood biochemistry and haematology of rabbits fed sun-dried, ensiled, and fermented cassava peel-based diets. The test diets designated A, B, C and D were completely randomised. Diet A, the control, was a 16.18 per cent CP (crude protein) weaner ration formulated from maize, maize offals, soya bean meal, blood meal, oyster shell, bone meal, vitamin premix, and common salt. Diets B, C and D were also weaner rations of, respectively, 16.10, 16.20 and 16.08 per cent CP in which 10 per cent maize of the control diet was replaced, respectively, with sun-dried, ensiled and fermented cassava peels. The diets were roughly iso-caloric. The haematological components of the study included packed cell volume (PCV), white blood cells (WBC), neutrophil (N), and lymphocytes (L). The biochemical parameters were serum creatinine, urea, bilirubin (total and conjugated), serum glutamic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), eosinophil, and blood sugar. Liver and kidney weights were also monitored. The results showed that PCV, WBC, N and L were affected (P0.05) among rabbits fed different dietary treatments. Vingt-quatre lapins mâles en sevrage de l\'espèce de Nouvelle - Zélande blanc × Chinchilla agé de 7 à 8 semaines et de poids moyen de 0.9 kg étaient divisés en 4 groups de 6 lapins chacun et employés dans un essai d\'alimentation de 12 semaines pour évaluer la biochimie et l\'hématologie de sang de lapins nourris de régimes à base de pelure de manioc séchée de soleil, ensilées et fermentée. Les régimes d\'essai classés A, B, C et D étaient complètement choisis au hasard. Le régime A, le contrôle, était une ration de sevrage avec 16.18% de CP (protéine brute) formulée de maïs, déchets de maïs, farine de graine de soja, farine sanguine, coquille d\'huître, engrais de cendres d\'os, vitamine prémix et sel ordinaire. Les régimes B, C et D étaient aussi des rations de sevrage, respectivement, avec 16.10, 16.20 et 16.08% de CP enquel 10% de maïs du régime de contrôle était remplacé par les pelures de manioc, respectivement, séchée de soleil, ensilées et fermentée. Les régimes étaient approximativement iso-cloriques. Les éléments hématologiques de l\'étude comprenaient la volume de cellule tassée (VCT), le globule sanguin blanc (GSB), le neutrophile (N) et les lymphocytes (L). Les paramètres biochimiques étaient le sérum créatinine, l\'urée, la bilirubine (totale et conjuguée), le sérum glutamique transaminase (SGPT), le sérum glutamique oxaloacétique transaminase (SGOT), l\'éosinophile et le sucre dans le sang. Les poids de foie et de rein étaient également suivis de près. Les résultats montraient que VCT, GSB, les neutrophiles et les lymphocytes étaient modifiés (
AMELIORATION OF ARSENIC-INDUCED TOXICITY BY ETHANOL LEAF EXTRACT OF PHYLLANTUS AMARUS LINN AND VITAMIN C IN MALE ALBINO RATS
The ameliorative effect of ethanol leaf extract of Phyllantus amarus (EEPA) and vitamin C in arsenic-induced toxicity was studied. Thirty-six (36) male albino rats divided into six groups of six (6) rats each were used for the study. Arsenic toxicity was induced in three of the groups by daily intake of 100 ppm of arsenic as Dimethylarsenate (DMA) in their drinking water. Two of the arsenic-exposed groups were treated with 200 and 500 mg/kg bwt of EEPA and vitamin C respectively. The third group was not treated during arsenic exposure. The fourth and fifth groups were positive control for P. amarus and Vitamin C respectively, while another group served as the normal control. All treatments were done orally for six weeks. The effects of treatments on lipid profile, lipid peroxidation and liver function were thereafter studied. Increased levels of total cholesterol, LDL-cholesterol and malondialdehyde (MDA) were observed in plasma and lymphocytes of untreated arsenic-exposed rats compared to the control group. Arsenic increased total cholesterol and LDL-cholesterol concentrations, while triacylglycerol concentration was reduced significantly. Treatments with EEPA and Vitamin C however ameliorated the dyslipidemia observed in arsenic-exposed groups. Exposure to DMA increased plasma activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of the animals, while plasma activity of ALT in rats treated with Vitamin C was not different compared to the control. Both treatments however, had no significant effect (p > 0.05) on the activity of plasma AST. P. amarus may therefore play a role in ameliorating arsenic-induced dyslipidemia in male albino rats.
 
Investigation into Alternative Energy Sources from Waste Citrus Peel (Orange): Approach to Environmental Protection
An experimental study has been carried out on an alternative source of energy from
citrus peel waste. A widely used material, pectin, has been extracted from orange peel
(OP) and subsequently converted into ethanol with the use of a bacteria and fungi.
Dried peels were split into several particle sizes of 0.075, 0.5, 1.0 and 5 mm. It was
noted that OP with 0.75 mm particle size produced pectin of low volume while larger
1.0 mm OP particle size produced a high pectin volume. OP of 802 g was used to
produce 1,770 ml of pectin, this illustrate that citrus fruit (specifically orange) contains
pectin in a large quantity. A mixture of E.coli (bacteria) with yeast (fungus), and their
individual components were used on pectin obtained. However, it was observed that a
mixture of pectin, E.coli & S. cerevisiae, and a combination of sample pectin with
E.coli produced an encouraging volume of ethanol as against no ethanol produced
when a mixture of sample pectin, yeast and pectin sample only. The amount of energy
contained in the gross ethanol produced was 1526.6 btu, this can be combined with
purified gasoline so as to attain the optimum energy content that can be used to run an
indigenous processing plant for citrus fruit in Nigeria
BIOCONVERSION OF ORANGE PEEL WASTE BY ESCHERICHIA COLI AND SACCHAROMYCES CEREVISIAE TO ETHANOL
An alternative energy sources using the sweet orange (Citrus sinensis (L.) waste as the feedstock was investigated, this is an approach to environmental protection. The extraction of pectin from sweet orange peel waste (pith) and the production of ethanol from the resultant liquid pectin with the aid of Escherichia coli (E.coli) and Saccharomyces cerevisiae (yeast) were carried out. Dried pith was separated using various particle sizes ranging from 0.075, 0.5, 1.0 and 5 mm. It was observed that pith with particle size of 1.0 mm produced a larger volume of pectin while the pith with particle size of 0.075 mm produced the least volume of pectin. 1,770 mL pectin was obtained from 802 g of pith, this shows that citrus fruit (especially orange) contains a high amount of pectin. E.coli (bacteria), yeast (fungus) and a mixture of both were added to the produced pectin which was fermented to Ethanol. It was however noticed that sample pectin + E.coli + yeast and sample pectin + E.coli produced a good volume of ethanol but sample pectin only and sample pectin + yeast did not produce ethanol. The energy content of the total produced ethanol is 1526.6 btu which can be mixed with pure gasoline to obtain an optimum energy content that can be used to power a citrus processing plant in Nigeria. The purpose of this paper is to obtain an alternative energy source for citrus plants using the waste generated by them such as Orange peel
High-Frequency Ultrasound Imaging of the Intestine in Normal Subjects and Patients with Intestinal Parasites
High-frequency ultrasound imaging was used to evaluate the intestinal walls of the duodenum and colon in patients with intestinal parasitic infections. Ultrasound images were obtained from 100 consecutive patients with symptomatic intestinal parasitic diseases and 40 healthy controls. High-frequency annular array transducer of 7.5 MHz was used to obtain B-mode ultrasound gray-scale and color images of the duodenum and colon with and without water contrast. The diagnosis of parasitic infections was based on clinical presentation, serial stool microscopy, and finding of parasites in duodenal aspirates. We demonstrated normal duodenum and colon echoanatomy in control subjects. In patients with giardiasis, the lesions of the duodenum and colon were associated with increased dimensions and wall thickness compared to healthy controls (p < 0.05). The ultrasound features of giardial lesions were characterized by increased wall echogenicity, flattening or loss of duodenal folds, and/or colonic haustration, hyperechoic floating foci demonstrating chaotic motility, increased perilesional tissue echogenicity, and altered colonic peristalsis. In amebic lesions there were hyperechoic floating foci with bulk motility. There is loss of wall thickness at amebic ulcer sites or wall thickening at amebic granuloma. Helminths were visualized as large hyperechoic linear or curvilinear foci with serpentine or jolting motility. In conclusion, high-frequency B-mode ultrasound imaging with water contrast demonstrated details of duodenal and colonic echoanatomy in normal subjects and patients with giardiasis
Association between composite scores of domain-specific cognitive functions and regional patterns of atrophy and functional connectivity in the Alzheimer's disease spectrum
Background: Cognitive decline has been found to be associated with gray matter atrophy and disruption of
functional neural networks in Alzheimer’s disease (AD) in structural and functional imaging (fMRI) studies. Most
previous studies have used single test scores of cognitive performance among monocentric cohorts. However,
cognitive domain composite scores could be more reliable than single test scores due to the reduction of measurement error. Adopting a multicentric resting state fMRI (rs-fMRI) and cognitive domain approach, we provide
a comprehensive description of the structural and functional correlates of the key cognitive domains of AD.
Method: We analyzed MRI, rs-fMRI and cognitive domain score data of 490 participants from an interim baseline
release of the multicenter DELCODE study cohort, including 54 people with AD, 86 with Mild Cognitive
Impairment (MCI), 175 with Subjective Cognitive Decline (SCD), and 175 Healthy Controls (HC) in the ADspectrum. Resulting cognitive domain composite scores (executive, visuo-spatial, memory, working memory
and language) from the DELCODE neuropsychological battery (DELCODE-NP), were previously derived using
confirmatory factor analysis. Statistical analyses examined the differences between diagnostic groups, and the
association of composite scores with regional atrophy and network-specific functional connectivity among the
patient subgroup of SCD, MCI and AD.
Result: Cognitive performance, atrophy patterns and functional connectivity significantly differed between
diagnostic groups in the AD-spectrum. Regional gray matter atrophy was positively associated with visuospatial
and other cognitive impairments among the patient subgroup in the AD-spectrum. Except for the visual network,
patterns of network-specific resting-state functional connectivity were positively associated with distinct
cognitive impairments among the patient subgroup in the AD-spectrum.
Conclusion: Consistent associations between cognitive domain scores and both regional atrophy and networkspecific functional connectivity (except for the visual network), support the utility of a multicentric and
cognitive domain approach towards explicating the relationship between imaging markers and cognition in the
AD-spectrum

Myo-inositol nutritional supplement for prevention of gestational diabetes (EMmY): a randomised, placebo-controlled, double-blind pilot trial with nested qualitative study.
OBJECTIVES: To determine the feasibility and acceptability of conducting a randomised trial on the effects of myo-inositol in preventing gestational diabetes in high-risk pregnant women. DESIGN: A multicentre, double-blind, placebo-controlled, pilot randomised trial with nested qualitative evaluation. SETTING: Five inner city UK National Health Service hospitals PARTICIPANTS: Multiethnic pregnant women at 12+0 and 15+6 weeks' gestation with risk factors for gestational diabetes. INTERVENTIONS: 2 g of myo-inositol or placebo, both included 200 µg folic acid, twice daily until delivery. PRIMARY OUTCOME MEASURES: Rates of recruitment, randomisation, adherence and follow-up. SECONDARY OUTCOME MEASURES: Glycaemic indices (including homoeostatic model assessment-insulin resistance HOMA-IR), gestational diabetes (diagnosed using oral glucose tolerance test at 28 weeks and by delivery), maternal, perinatal outcomes, acceptability of intervention and costs. RESULTS: Of the 1326 women screened, 58% (773/1326) were potentially eligible, and 27% (205/773) were recruited. We randomised 97% (198/205) of all recruited women (99 each in intervention and placebo arms) and ascertained outcomes in 90% of women (178/198) by delivery. The mean adherence was 52% (SD 44) at 28 weeks' and 34% (SD 41) at 36 weeks' gestation. HOMA-IR and serum insulin levels were lower in the myo-inositol vs placebo arm (mean difference -0.6, 95% CI -1.2 to 0.0 and -2.69, 95% CI -5.26 to -0.18, respectively). The study procedures were acceptable to women and healthcare professionals. Women who perceived themselves at high risk of gestational diabetes were more likely to participate and adhere to the intervention. The powder form of myo-inositol and placebo, along with nausea in pregnancy were key barriers to adherence. CONCLUSIONS: A future trial on myo-inositol versus placebo to prevent gestational diabetes is feasible. The intervention will need to be delivered in a non-powder form to improve adherence. There is a signal for efficacy in reducing insulin resistance in pregnancy with myo-inositol. TRIAL REGISTRATION NUMBER: ISRCTN48872100
