10-Year Risk of Developing Type 2 Diabetes Mellitus: A Survey of Rural Communities in Southern Nigeria.

BACKGROUND: The exponential rise in the prevalence of Type 2 Diabetes (T2DM) necessitates the introduction of strategies for early diagnosis to reduce the burden of the disease. This study assessed the prevalence of prediabetes and also determined the 10-year risk of developing T2DM in Southern Nigerian rural communities by adopting the validated Finnish Diabetes Risk Score (FINDRISC) tool. METHODS: 273 participants from 3 Southern rural communities aged 18 years and older were recruited in this cross-sectional study. Data in the FINDRISC stratification tool and Random Blood Glucose (RBG) variables were obtained for the participants. IBM SPSS version 21 was used to analyze the data with a level of significance put at p < 0.05. RESULTS: The participants' mean age was 54.20±16.61 years. The prevalence of prediabetes among the study participants based on RBG was 4.8% (3.8% of males and 6.6% of females, respectively). Most of the study participants (41%) had a low risk of developing T2DM which meant that 1 in 100 participants would become diabetic in a 10-year period, based on the FINDRISC scale. Amongst the male participants, the Total Diabetes Risk Score (TDRS) showed significant positive correlation with the RBG (r=0.315, p=0.001); similarly, a weak positive correlation between TDRS and RBG was noted among female participants. CONCLUSION: The propensity of developing T2DM in 10 years was indisputably low amongst rural dwellers in the Southern Nigerian rural communities studied. Further studies to compare the risk of developing T2DM between rural and urban communities would be required.

CONTEXTE: L'augmentation exponentielle de la prévalence du diabète de type 2 (DT2) nécessite l'introduction de stratégies de diagnostic précoce pour réduire le fardeau de la maladie. Cette étude évalue la prévalence du prédiabète et détermine également le risque sur 10 ans de développer un DT2 dans les communautés rurales du sud du Nigeria en adoptant l'outil validé FINDRISC (Finnish Diabetes Risk Score). MÉTHODES: 273 participants de 3 communautés rurales du sud du pays âgés de 18 ans et plus ont été recrutés dans cette étude transversale. Les données de l'outil de stratification FINDRISC et les variables de la glycémie aléatoire (RBG) ont été obtenues pour les participants. IBM SPSS version 21 a été utilisé pour analyser les données avec un niveau de signification mis à p < 0,05. RÉSULTATS: L'âge moyen des participants était de 54,20±16,61 ans. La prévalence du prédiabète parmi les participants à l'étude, basée sur le RBG, était de 4,8% (3,8% des hommes et 6,6% des femmes respectivement). La plupart des participants à l'étude (41%) présentaient un faible risque de développer un DT2, ce qui signifie que 1 participant sur 100 deviendrait diabétique sur une période de 10 ans, selon l'échelle FINDRISC. Chez les hommes, le score total de risque de diabète (TDRS) a montré une corrélation positive significative avec le RBG (r=0,315, p=0,001) ; de même, une faible corrélation positive entre le TDRS et le RBG a été notée chez les femmes. CONCLUSION: La propension à développer un DT2 en 10 ans est indiscutablement faible chez les habitants des communautés rurales du sud du Nigeria étudiées. D'autres études visant à comparer le risque de développer un DT2 entre les communautés rurales et urbaines seraient nécessaires.

Antisickling effect of chrysin is associated with modulation of oxygenated and deoxygenated haemoglobin via alteration of functional chemistry and metabolic pathways of human sickle erythrocytes.

Sickle cell disease (SCD) treatment and management remain a challenging puzzle especially among developing Nations. Chrysin's sickling-suppressive properties in human sickle (SS) erythrocytes in addition to its effect on AA-genotype erythrocytes were evaluated. Sickling was induced (76%) with 2% sodium metabisulphite at 3 h. Chrysin prevented (81.19%) the sickling and reversed same (84.63%) with strong IC50s (0.0257 µM and 0.00275 µM, respectively). The levels of oxygenated haemoglobin in the two groups (before and after induction approaches) were similar but significantly (P < 0.05) higher than that of SS erythrocytes (the 'induced' control), with chrysin-treated AA-genotype showing no effects relative to the untreated. The level of deoxygenated haemoglobin in the 'induced' control group was significantly (P < 0.05) higher than those of the chrysin-treated SS erythrocytes. Normal and chrysin-untreated erythrocytes (AA-untreated) were significantly more resistant to osmotic fragility than the SS-untreated. However, treatment with chrysin significantly reduced the osmotic fragility of the cells relative to the untreated cells. Furthermore, chrysin treatment significantly lowers the high level of 2,3-diphosphoglycerate (2,3-DPG) observed in the sickle erythrocytes, with no effects on AA-genotype erythrocytes. Based on functional chemistry, chrysin treatment alters the functional groups in favour of its antisickling effects judging from the observed bends and shifts. From metabolomics analysis, it was observed that chrysin treatment favors fatty acid alkyl monoesters (FAMEs) production with concomitant shutting down-effects on selenocompound metabolism. Thus, sickling-suppressive effects of chrysin could potentially be associated with modulation of oxygenated and deoxygenated haemoglobin via alteration of human sickle erythrocyte's functional chemistry and metabolic pathways implicated in SCD crisis.

Growth response, nutrient and mineral retention, bone mineralisation and walking ability of broiler chickens fed with dietary inclusion of various unconventional mineral sources.

Growth response, nutrient and mineral retention, bone mineral content and walking ability of broiler chicken fed dietary inclusion of various unconventional calcium sources were studied using 160-day-old broilers. Four isonitrogenous, isocaloric diets balanced for Ca and P were formulated such that oyster shell, snail shell, wood ash and limestone were used as main non-phytate (Ca from other sources apart from plant) calcium sources. Each dietary treatment consisted of 40 birds replicated four times with 10 birds per replicate. A single diet was fed to the broilers throughout the duration of the study which lasted for 8 weeks. Broilers fed diet containing oyster shell as calcium sources recorded the highest (p < 0.05) feed intake of 5863.30 g, while those fed diet containing limestone consumed the least intake (p < 0.05) of 5432.56 g. Occurrence of lameness and evidences of gaits were highest (p < 0.05) for broilers fed diet containing wood ash. Lowest (p < 0.05) Ca and ash retention were recorded for broiler fed diet containing wood ash as Ca sources. Similar tibia ash values were recorded for broilers fed oyster shell, snail shell and limestone. Wood ash inclusion resulted in a low Ca availability hence its inclusion in feeds for broilers should be discouraged.

Biochemical infertility among females attending University of Ilorin Teaching Hospital, Nigeria.

BACKGROUND: Biochemical laboratory investigations potentially contribute to the diagnosis of over 50-75% of couples being investigated for infertility. Both hormonal and anti-hormonal treatments have achieved great successes in the treatment of infertility. Our aim therefore was to investigate the pattern of biochemical abnormalities in females diagnosed as infertile form anovulation. MATERIAL AND METHODOLOGY: One hundred and twenty women diagnosed clinically as primary or secondary infertility from anovulation referred from the gynecological clinic of UITH and private hospitals in Ilorin were investigated by routine fertility test profile. RESULT: The age ranged between 20-40 years (mean = 32.9, sd +/- 4.7) for the primary infertility and 23-47 years (mean = 34.4, sd +/- 5.4) for the secondary infertility groups respectively. Ninety six (80%) subjects were found to have hormonal abnormalities. Pattern of biochemical diagnosis amongst the 33 (34.4%) primary infertility subjects included hypergonadotrophic hypogonadism 21 (63.6%), hypogonadotrophic hypogonadism 9 (27.3%), and hyperprolactinemia 3 (9.1%). Among the 63 (65.6%) cases of secondary infertility, there were 31 (49.2%) cases of hypergonadotrophic hypogonadism, 30 (47.6%) hypogonadotrophic hypogonadism, and 2 (3.2%) hyperprolactinemia. There was no statistical difference in the mean values in the various biochemical parameters. CONCLUSION: Hormonal profile should be a goal standard in the diagnosis of anovulation.

Mycoflora, and mycotoxins production in Nigerian corn and corn-based snacks.

Thirty-one fungal species, mostly toxigenic and belonging to 11 genera were isolated from corn, corn cake and corn roll snack samples. Aspergillus, Penicillium and Fusarium accounted for 10, 6 and 3 of the species and altogether, they constituted 90, 94 and 88 percent of the total fungi in corn, corn cake and corn roll snack respectively. Mycotoxins (aflatoxins and ochratoxin A) were detected in 45, 80 and 12 percent while the means and ranges of the total aflatoxins recorded were: 200(25-770 ppb); 233(15-1070 ppb) and 55(10-160 ppb) for corn, corn cake and corn roll snack samples respectively. Ochratoxin A was detected at toxicologically significant levels in only 15 percent of the corn cake samples analyzed. All the strains of Aspergillus flavus and A. ochraceus tested produced aflatoxin B and ochratoxin A, respectively, when they were cultured on each of the three substrates. In each case, substantial quantities of the toxins were produced from 25 to 35 degrees C with the peak level recorded at 30 degrees C. Toxin production was detected only in substrates with 15 percent moisture content and above; reaching the maximum at 25 or 30 percent moisture level. No substantial differences in the amount of toxins were elaborated with further increase in substrates' moisture content. Of the three substrates, corn cake was the most suitable for aflatoxin B production while they were all equally suitable for the elaboration of ochratoxin A.

Mycoflora and aflatoxins in a west African corn-groundnut based convenience food.

A total of 14 fungal species, mostly toxigenic, were isolated from 50 samples of 'donkwa' snack obtained from 16 producers. All of the isolates recorded substantial growth, though at varying rates, on the 2% snack agar provided. They also induced a reduction in the oil and an increase in free fatty acids of the substrate suggesting their participatory roles in deterioration. Most of the snack samples analysed contained initial amounts of aflatoxins above the 'safe' permissible level (30 ppb). The initial toxin levels increased substantially with storage time under 79.5, 89.5 and 100% ambient relative humidities but increased only slightly when samples were kept at 71% relative humidity. Almost constant toxin levels were recorded throughout the study period under 51% relative humidity. Accumulation of aflatoxin B1 in samples was most enhanced at 89.5% relative humidity. Comparatively, greater amounts of aflatoxin B1 accumulated under all conditions than the amounts recorded for aflatoxin G1.
