In the global frame aiming at assessing bacterial susceptibility for safer and cost-effective healthcare, the present survey was conducted in three hospitals: Bafoussam Regional Hospital (BRH), Bangwa Protestant Hospital (BPH) and Bangangté District Hospital (BDH). Sampling was performed by fingerprinting on culture media and swabbing of hospital devices or surfaces. Wards of interest included: Pediatrics, Medicine, Operating Theater, Intensive Care Unit, Maternity, and, in the BDH, Laboratory in addition. Culture, isolation, identification and susceptibility tests were conducted according to standard guidelines and assigned contamination rates. Seventeen antibacterial agents were chosen and included representatives of major families of antibiotics used in Cameroon. Analysis of 238 specimens revealed 90%, 86% and 92% contamination rates in the BRH, BPH, and BDH, respectively. On healthcare provider's hands, the respective rates were 63%, 100% and 91%. Bacillus and Staphylococcus were predominant bacteria types in all settings (BPH: 92%; BDH: 86%; BRH: 81%). Susceptibility profiles indicated high resistance rates and clonal distribution in all settings; and most reduced susceptibility with common drugs. Further investigations and previous works alleged drug use and basic hygiene as crucial in addressing resistance issues for safer care. This would be achieved with State support to public and private institutions.
Background and aim: The increase in the incidence of diabetes mellitus is one of the constellations of cardiometabolic risk in the world. As the specific diagnostic thresholds for dysglycemia are absent among African Bantou de Brazzaville, Republic of Congo justified this study. The aim of the study was to determine the performance of glycated hemoglobin in the diagnosis of dysglycemia. Methods: The cross-sectional survey involved 500 apparently healthy adult participants. The glycated hemoglobin was modelled using a National Glycohemoglobin Standardization Propram certified method and correlated with the Diabetes Control and Complication Trial. Diagnostic performance was defined using analysis of the receptor's operating characteristics. Results: The study included 225 men and 275 women, the mean age was 47.4-13.7 years, the levels of hemoglobin glycated on an everan erate equal to 5.5-5.9% and 6.0% (Se100% and Sp-100%) (p = 0.001) were characterized by perfect diagnostic performance and prevalence respectively for intermediate/prediabetes-sweetened hyperglycemia (13.8%) and diabetes mellitus (24.4%) with an area under curve equal to one. There was a positive and significant bivariate correlation between older age, fasting blood glucose, and increasing hemoglobin glyched to right Y (glycated hemoglobin) – 2.683; -0.077 - Age (years) - 0.789 - Glycemia (mmol/L). Conclusion: The epidemic of cardiometabolic risk was estimated to be 2/3 of prehypertension/high blood pressure, 4/10 of overweight/obesity and 1/4 of diabetes mellitus in 2018 and significantly higher than reported in 2004. This study showed that the recommended thresholds for diagnosing dysglycemia are not the same for Bantu populations
Background: Glucose-6-phosphate dehydrogenase deficiency is an enzymopathy characterized by insufficient production of reduced glutathione (GSH), a molecule known for its antioxidant role. This lack of GSH leads to a deficit in the elimination of peroxide ions from the red blood cells, causing thereby hemolytic accidents, which can be fatal if not properly managed. In neonates, the clinical picture is most often that of neonatal jaundice. Objectives: This study aimed to determine the place of G6PD deficiency as a cause of neonatal jaundice at Essos Hospital Centre. Methods: We conducted a prospective descriptive study over three months. Blood samples taken from newborns aged 0 to 28 days were analyzed in the medical analysis laboratory of the Essos Hospital Centre in Yaoundé. We carried out a determination of the enzymatic activity of G6PD, a blood count and the determination of the bilirubin level. The results obtained were analysed using R statistical software version 4.1.1. Linear regression analyses were used to assess correlations between the variables of interest. Results: Sixty-nine icteric neonates constituted our study population, with a total of 40 boys (58%) and 29 girls (42%) with a sex ratio of 1.37 in favour of boys. The prevalence of G6PD deficiency in icteric children was 50.72%. The mean hemoglobin was 15.3 ± 3.08 g/dL and the mean red blood cell count was 4.52 ± 1.01 × 10 6 /mm 3 . The mean total bilirubin was 122 ± 48.3 mg/L with a maximum of 308 mg/L and the mean free bilirubin was 104 ± 46.6 mg/L with a maximum of 292 mg/L. Furthermore, after linear regression analysis, we obtained a positive and significant correlation between G6PD enzymatic activity and hemoglobin level (r = 0.33; p ≤ 0.001), G6PD red blood cell level (r = 0.26; p < 0.001
Background. The diagnosis of neonatal hemolysis is an easy exercise. However, the diagnosis of its etiology can be very challenging especially in low ressources countries where laboratory capacities are limited. We report the case of hemolytic anemia episodes that started in the neonatal period, for which the trigger factor, infectious of paracetamol, is debatable.
Introduction. Sickle cell disease is an autosomal recessive inherited disorder due to the mutation of a gene coding for the globin beta chain. The aim of this study is to update the epidemiological data on hemoglobinoses, in particular sickle cell disease in newborns in Congo. Materials and Methods. This was a descriptive cross-sectional study, conducted from October 1, 2019, to March 31, 2020, throughout the Congolese national territory. It involved all full-term newborns, without distinction of nationality, aged 5 days or less, and whose parents consented to participate in the study. The blood samples, taken at the heel and collected on Whatman blotting paper, were analyzed using the HPLC Variant NBS machine. Results. In 2897 newborns (NN) screened, hemoglobin abnormalities were found in 603 NN (20.81%). The mean age of these newborns was 1 day (extremes 0 and 5 days). The male-to-female ratio was 1.03. Abnormal hemoglobins were mainly Hb S (n = 597 (97.71%)); Hb C (n = 5 (0.82%)); and variants (n = 7 (1.15%)). The national prevalence of major sickle cell (MSC) syndromes and sickle cell trait was 1.35% and 19.43%, respectively. The prevalence ranged from 1.77% to 2.56% for MSS in four departments and from 20.5% to 25.8% for the sickle cell trait in six other departments. Conclusion. Data on homozygous sickle cell disease remain consistent with previous studies. However, further studies should clarify the molecular anomalies of the variants observed in our samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
