Diabetes is a chronic pathology whose evolution is marked by micro and macroangiopathic complications. Optimal management can prevent the onset of complications and improve patients’ quality of life. Objectives: To determine the frequency of self-monitoring of blood glucose and to describe the errors found during self-monitoring in diabetic patients followed at the Endocrinology Department of Donka University Hospital in Guinea. Materials and methods: Descriptive cross-sectional study carried out between August and September 2020 involving diabetic patients followed up at the Endocrinology and Diabetology Department of the Donka National Hospital, CHU Conakry. Results: A total of 301 patients were enrolled, with an average age of 44.24 ± 21.01 years. 64.12% were female. Type 2 diabetes predominated in 64% of cases. The mean duration of diabetes was 6.14 ± 4.67 years, and 75.08% of patients lived in urban areas. Patients were on insulin in 36.21% of cases, insulin and biguanides (26.25%), hypoglycemic sulfonamide and biguanides (19.27%) and biguanides in 18.27% of cases. The frequency of self-monitoring of blood glucose was 43%, and 38% of patients made errors, notably reusing lancets (60%), not checking the expiration date (55.65%) and not washing their hands (48%). Conclusion: This study shows that self-monitoring of blood glucose is not performed by the majority of patients. Numerous errors were identified during blood glucose testing. Continued therapeutic education on the use of blood glucose meters will help empower patients and improve their quality of life.

Macrosomia is defined as a term birth weight greater than or equal to 4000 grams, or greater than the 90 percentile of intrauterine growth curves. Excessive weight has harmful consequences for the newborn and is a major health concern. Objectives: To determine the frequency of neonatal macrosomia, describe risk factors and neonatal and maternal complications. Materials and methods: This was a cross-sectional study carried out between January and December 2022, involving newborns whose birth weight was greater than or equal to 4000 grams admitted to the neonatology unit of the Labe regional hospital. Results: 591 deliveries were recorded, 15 of which were macrosomic, representing a frequency of 2.54%. The average age of the women was 30.26 years. History of fetal macrosomia and diabetes was 93.33 and 71.43% respectively. The mean gestational age was 38.71 ± 0.75 SA, the mean antenatal consultation was 3 ± 0.8 and the mode of delivery was caesarean section (66.67%). Third-trimester ultrasound was performed in 53.33% of cases. Macrosomic newborns were male in 80% of cases. Neonatal complications were asphyxia (60%), hypoglycemia (20%) and hypocalcemia (13.33%). Factors associated with neonatal macrosomia were diabetes (P < 0.001), history of macrosomia (P Conclusion: this study shows that the frequency of neonatal macrosomia is 2.54% with high neonatal morbidity among newborns hospitalized in the neonatology unit of the Labé regional hospital. Screening for macrosomia risk factors during pregnancy is essential to prevent perinatal complications.

Introduction: Diabetes mellitus and hypertension are chronic diseases that are on the rise and pose a major public health problem among the priorities of healthcare systems. Objectives: Determine the prevalence of diabetes and hypertension and describe the sociodemographic characteristics of those screened. Materials and Methods: This was a cross-sectional study organized during a diabetes and hypertension screening campaign that took place in Conakry and five (05) inland regions on November 14, 2022. Results: 2050 people were screened, of whom 33.12% were housewives, the average age was 44.78 ± 16.23 years, and 55.27% were women. The screening sites were the city of Conakry 741 (36.15%), the Labé region 424 (20.68%), the N’Zérékoré region 298 (14.54%), the Faranah region 241 (11.75%), the Mamou region 210 (10.24%) and the Boké region 136 (6.63%). The prevalence of diabetes and hypertension were respectively 12.5% and 43.38% for the Boké region;6.19% and 16.19% for the Mamou region;3.02% and 21.81% for the N’Zérékoré region;31.95% and 13.69% for the Faranah region;9.67% and 20.28% for the Labé region;2.83% and 20.28% for the city of Conakry. Conclusion: Despite the limitations of the study duration, our series highlighted the high prevalence of diabetes and hypertension among people screened on World Diabetes Day 2022. Raising public awareness of a healthy lifestyle is essential for the prevention and control of diabetes and hypertension.

Objective: To determine the prevalence of diabetes and the level of cardiovascular risk in tuberculosis patients treated in Conakry and surrounding towns. Method: This was a cross-sectional study carried out at tuberculosis treatment centers in Conakry and surrounding towns (Coyah and Dubréka) on World TB Day, November 14, 2022, among 350 tuberculosis patients. We determined the proportion of TB patients with diabetes and high hyperglycemia. We determined the Chi-square to identify the factors associated with the occurrence of diabetes in tuberculosis patients, and a significance threshold with p Results: The average age of participants was 33.5 ± 14.5 years, and they were predominantly male (59.7%). The majority of participants lived in Conakry (96.3%). 5.7% were known diabetics and 4.6% were known hypertensives. We found a prevalence of diabetes of 9.4%. Among diabetics, 39% were diabetes discoveries. 30% were hypertensive or had high blood pressure. Of these hypertensive patients, 26.4% were unrecognized hypertensives. Age and hypertension were statistically significantly associated with the onset of diabetes in tuberculosis patients. Medium, high and very high levels of cardiovascular risk were present in 23.4%, 8.9% and 3.4% respectively. Conclusion: Diabetes is common in tuberculosis patients. Cardiovascular risk factors, notably hypertension and cardiovascular risk level, are frequently associated with tuberculosis. Tuberculosis patients with cardiovascular risk factors should be screened for diabetes.
