Conducted over a period of six months, from February 18 to July 18, 2021, this prospective and descriptive cross-sectional study involved 220 diabetic patients. Among these, 48 patients (22%) maintained balanced glucose levels (2 g/l). Positive glycosuria was observed in 54% of the patients, whereas 46% demonstrated normal glycosuria. An analysis of urinary parameters revealed that 15% of the patients had abnormal Ketone Bodies. Normal HbA1c levels (9%) HbA1c levels. Hematological assessments indicated significant variation: 56% of the patients had low hemoglobin levels, 4% suffered from hyper-eosinophilia, and 1% each from hyper-basophilia and hyper-hemoglobinemia. The anemic profile was characterized as mild anemia in 75%, moderate anemia in 20%, and severe anemia in 5%. Furthermore, 25% of patients were affected by Microcytic anemia and 75% by Normocytic anemia. Demographically, women constituted 65% of the study group compared to 35% of men. The most represented age bracket was 41 to 60 years, accounting for 52% of the patients, while those between 61 and 80 years comprised 36%. Every district in Kindia was impacted by diabetes.展开更多

In Africa, and in Senegal in particular, the handling and management of electronic and electrical equipment (EEE) that has reached the end of its life is mainly informal. This professional environment is characterized by the disintegration of the sector and the social heterogeneity that can be found there. The objective of this study is to assess the standard of living of electrical and electronic equipment waste handlers in the Dakar region, as well as their perception of their health. A survey was used to obtain information on sociodemographic background, living arrangements, perception of health status, and good practices to be implemented in case of work-related health problems. Life style, perception of general health and health problems were ranged as excellent, very good, good, average and poor. Informal recyclers in the Dakar region lived mainly in rooms and buildings as tenants (49.1%), or in family homes (48.4%) before starting this activity, and 51.2% continue to live in rooms and buildings as tenants compared to 41.4% who still live in a family home. The perception of health status ranged from poor to excellent, and 4.9% believe that they are limited in work due to a disability or health problem. Informal work is a heterogeneous phenomenon that makes research and policymaking particularly complex. There are several external factors within informal WEEE re-cyclers that can cause health problems or functional disability. However, the living conditions and the perception they have of their state of health are contradictory to the working conditions and the social environment to which they belong. A biomedical approach would consolidate these achievements by confirming or invalidating them.展开更多

On the other hand, blind supplementation of vitamin A, for children in developing countries is a subject of controversy in the literature. The crucial role of vitamin A in the process of spermatogenesis in adult rodents is well established, but only a few publications are consecrated to the long-term effect of vitamin A intake at a young age on testicular development and differentiation. Objectives: Our study aimed to evaluate the long-term effects of acute supplementation at an early age, in the post-natal period, on spermatogenesis and testicular trophicity at adult age. Material and Methods: Young Wistar Albinos rats of 22 days received an acute high dose of supplementation of vitamin A (retinyl palmitate). The control group, group 1, received only extra virgin olive oil, Group 2 a dose of 7000 IU/kg of retinyl palmitate, group 3, 14,000 IU/kg, and Group 4 a dose of 28,000 IU/kg. At 10 weeks of age, the testes’ testosterone levels were measured by ELISA. For histological assessment, sections were stained with Hematoxylin eosin, and the Johnsen score was used to evaluate spermatogenesis in the seminiferous tubules. Results: The average testicular weights of rats were significantly lower in group 4 (p < 0.05), and so was the testosterone level in the testis compared to the control group (p .01). Most of the seminiferous tubules were concerned by an arrest of spermatogenesis and the Johnsen score was decreased with a mean score of 5.96 ± 1.60 (p .001) in that Group. In Group 3, Johnsen’s score was significantly better than the one obtained with the control. Conclusion: We observed a negative effect in the long term with a high acute dose of supplementation of retinyl palmitate at a young age, on testicular development and differentiation. Despite a return to normal diet after that supplementation, during childhood, impaired spermatogenesis was identified at the adult age with an arrest of spermatogenesis. The reversibility of that lack of differentiation by a return to a normal diet is questionable and would need more investigation.展开更多

It contributed valuable epidemiological data on dyslipidemia in the studied population, emphasizing gender, age, and socio-professional categories, which could inform tailored prevention and management strategies in improving the health care of dyslipidemia patients by proposing diets to help these patients better manage their disease and a food system for preventing dyslipidemia. The study focused on the lipid profile of patients seen at the cardiology department at the Ignace DEEN National Hospital Republic of Guinea (Conakry). This was a prospective, descriptive study lasting six (6) months from January 24 to July 23, 2021;aimed at determining the frequency of lipid abnormalities and pathologies related to the lipid profile. A total of 523 people were included in this study with a female predominance of 59.34% compared to 40.66% of males for a ratio of 1.5 in favor of women. The age groups of 45 - 54 and 55 - 65 were the most affected with respective frequencies of 45.42% and 30.03%. The most represented socio-professional category was that of housewives, i.e. 45.78%, followed by traders 18.68%. Our series was dominated by the married couple, i.e. 77.29%. Dyslipidemia constitutes a modifiable cardiovascular risk factor in patients seen in the cardiology department at the Ignace DEEN Hospital;its control must be strict through the use of hygienic and dietary rules and hypolipidemia medications.展开更多

Workers in this professional environment do not have access to individual and collective means of protection adapted to the activity, which exposes them to the dust emitted during their activity and therefore contributes to increasing the risk of developing respiratory disorders in this population. Objective: Our study aimed to evaluate the ventilatory function of metal welders in the city of Dakar. Method: This was a comparative study based on the analysis of the spirometric parameters of metal welders working in the city of Dakar (Senegal) with those of a control group of the same kind, selected from the general population. Measurements of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and maximum mid expiratory flow (MMEF) were measured. Results: A total of 75 men between the ages of 19 and 61 were recruited and divided into two groups (43 controls and 32 welders). The welding population had more frequent distal and central obstructions and pulmonary restriction compared to the control group. The metals most commonly used by welders were aluminum for welders who had an obstruction, while for those who had a restriction, iron was the most used metal. Signs of metal fever were frequently found in welders, especially those with ventilatory disorders. Conclusion: The prevalence of respiratory disorders observed is close to that observed in industrial environments, where exposure levels are the highest. The lack of personal protective equipment could also be a significant risk factor in the development of these disorders.展开更多

However, few researchers have devoted themselves to their toxicity, unlike the leaves. However, in the traditional pharmacopoeia, the indications for use are very different. The aim of our study was to study the effect of the administration of methanolic extracts of roots of L hastata on renal tissue, using an animal model. Materials and Methods: a cohort of 18 rats was studied with a random distribution of the animals in 3 groups (n = 6). The first group was the control group. The treated groups (Group II and III) received the methanolic extract of L. hastata with an administration of 500 mg / kg / day and 1000 mg / kg / day respectively, for 28 days. Results: The dose of 1000 mg / kg / day was lethal in group III, from the first week in females. Serum creatinine was significantly higher in rats given the root extract. There was kidney damage with vacuolar degeneration starting at 500 mg / kg / day. The lesions were more severe in group III with glomerular involvement characterized by retraction in the renal corpuscles. Conclusion: If the leaves of L hastata seem to be safe for consumption according to the majority of authors in the literature, the roots of this same plant could be harmful. In addition to the lethality observed at the doses tested, the lesions in the renal parenchyma would be dose-dependent.展开更多

In Guinea, whether by choice or necessity, traditional medicine and herbal remedies are the primary recourse for the population, both in rural and urban areas. Previous investigations led to the development of two phytomedicines designed for managing essential hypertension (HTN) and type 2 diabetes (DT2), named “Guinex-HTN®” and “Sattagas.” An evaluation of their therapeutic benefits was conducted during a prevalence survey carried out in Dubréka. This survey revealed a prevalence of 73.52% (211/287) for HTN, 36.58% (105/287) for DT2, and 33.45% (96/287) for combined DT2/HTN. The therapeutic potential of Sattagas and the combination of Sattagas with Guinex-HTN were assessed in diabetic and hypertensive diabetic patients, respectively. Comparisons were made between Sattagas, Metformin, Sattagas plus Metformin, and Sattagas plus Guinex-HTN regarding their impact on blood glucose levels and/or blood pressure values. After 6 months of treatment with 2 x 2 capsules per day, the anti-diabetic potential of Sattagas was confirmed by a significant reduction in blood glucose levels (from 2.59 ± 0.43 to 1.22 ± 0.43) in 80.95% (85/105) of patients, as well as a significant decrease in blood pressure values (from 177 ± 20.77/98 ± 10.70 to 149 ± 29.02/85 ± 13.64) in 90.16% (55/61) of hypertensive diabetics. The anti-diabetic effect of Sattagas (from 2.19 ± 0.29 to 1.22 ± 0.31 g/l) was similar to that of Metformin (from 2.14 ± 0.23 to 1.28 ± 0.41 g/l), and a synergistic effect was observed when Sattagas was combined with Metformin (from 2.21 ± 0.49 to 1.10 ± 0.20 g/l). In hypertensive diabetics, the combination of Sattagas and Guinex-HTN demonstrated a beneficial effect on blood pressure values. Except for some symptoms (epigastric pain, nausea, diarrhea, drowsiness, fatigue) reported in 17 out of 103 patients that did not interfere with the continuation of treatment, both phytomedicines were well tolerated. Sattagas and Guinex-HTN, two products derived from Guinean pharmacopoeia, represent interesting and accessible alternatives for managing type 2 diabetes and hypertension, particularly among underprivileged populations in rural and urban areas of Guinea.展开更多
