The development of.receptive endometrium(RE) f.om pre-receptive endometrium(PE) f.r successf.l embryo implantation is a complex dynamic process in which the morphology and physiological states of.the endometrial epithelium undergo a series of.signif.cant changes, including cell prolif.ration and apoptosis. However, the molecular mechanisms are not yet f.lly understood. In this study, a higher circRNA3669 level was observed in PE than in RE of.goats. f.nctional assays revealed that this overexpression promoted the prolif.ration of.goat endometrial epithelial cells(GEECs) by activating the expression of.genes related to the PI3K/AKT-mTOR and MAPK pathways,thereby inhibiting apoptosis in vitro. f.rthermore, circRNA3669 f.nctioned as a competing endogenous RNA(ceRNA) to upregulate Reticulocalbin-2(RCN2) expression at the post-transcriptional level by interacting with and downregulating miR-26a in GEECs. In addition, RCN2, which is highly expressed in the PE of.goats, was f.und to be regulated by β-estradiol(E2) and progesterone(P4). Our results demonstrated that RCN2 also af.ected the key proteins PI3K, AKT, mTOR, JNK, and P38 in the PI3K/AKT-mTOR and MAPK pathways, thereby f.cilitating GEECs prolif.ration and suppressing their apoptosis in vitro. Collectively, we constructed a new circRNA3669-miR-26aRCN2 regulatory network in GEECs, which f.rther provides strong evidence that circRNA could potentially play a crucial regulatory role in the development of.RE in goats.

Introduction: Cranioencephalic trauma caused by bladed weapons is rare, and that caused by sharp objects is exceptional. The aim of.our study was to describe the clinical, therapeutic and evolutionary aspects. Materials and method: This was a descriptive and analytical study over a 48-month period at CHU la Renaissance f.om January 1, 2018 to December 31, 2021, concerning patients admitted f.r penetrating cranioencephalic trauma by pointed object. Results: Twelve cases, all male, of.penetrating cranioencephalic sharp-f.rce trauma were identif.ed. The mean age was 34 ± 7 years, with extremes of.11 and 60 years. f.rmers and herders accounted f.r 31% and 25% of.cases respectively. The average admission time was 47 hours. Brawls were the circumstances of.occurrence in 81.2% of.cases. Knives (33%), arrows (25%) and iron bars (16.6%) were the objects used. Altered consciousness was present in 43.8% of.cases, and f.cal def.cit in 50%. Scannographic lesions were f.acture and/or embarrhment (12 cases), intra-parenchymal haematomas (6 cases) and presence of.object in place (4 cases). Surgery was perf.rmed in 11 patients. Postoperative outcome was f.vorable in 9 patients. Af.er 12 months, 2 patients were declared unf.t. Conclusion: Penetrating head injuries caused by sharp objects are common in Chad. Urgent surgery can prevent disabling af.er-ef.ects.

background: Venous thromboembolism (VTE) is a major public health problem due to its increasing f.equency, mortality and management cost. This cost may require major f.nancial ef.orts f.om patients, especially in developing countries like ours where less than 7% of.the population has health insurance. This study aimed to estimate the direct cost of.managing VTE in three ref.rence hospitals in Yaoundé. Methods: This was a cross-sectional retrospective study over a three-year period (f.om January 1st 2018 to December 31 2020) carried out in the Cardiology departments of.the Central and General Hospitals, and the Emergency Centre of.the city of.Yaoundé. All patients managed during the study period f.r deep vein thrombosis and pulmonary embolism conf.rmed by venous ultrasound coupled with Doppler and computed tomography pulmonary angiography respectively were included. f.r each patient, we collected sociodemographic and clinical data as well as data on the cost of.consultation, hospital stay, workups and medications. These data were analysed using SPSS version 23.0. Results: A total of.92 patient’s records were analysed. The median age was 60 years [48 - 68] with a sex ratio of.0.53. The median direct cost of.management of.venous thromboembolism was 766,375 Cf.f.[536,455 - 1,029,745] or $1415 USD. Management of.pulmonary embolism associated with deep vein thrombosis was more costly than isolated pulmonary embolism or deep vein thrombosis. f.ctors inf.uencing the direct cost of.management of.venous thromboembolism were: hospital structure (p = 0.015), health insurance (p 0.001), type of.pulmonary embolism (p = 0.021), and length of.hospital stay (p = 0.001). Conclusion: Management of.VTE is a major f.nancial burden f.r our patients and this burden is inf.uenced by the hospital structure, health insurance, type of.pulmonary embolism and length of.hospital stay.

Introduction: Malaria remains a public health priority in Senegal, particularly in Tambacounda, where it is one of.the main causes of.child mortality. The objective of.this work was to evaluate the care of.children under 10 years of.age hospitalized at the Tambacounda Health Center and the f.ctors associated with recovery. Methods: An analytical, retrospective, and descriptive cross-sectional study with exhaustive recruitment of.children 0 to 120 months hospitalized at the Tambacounda ref.rence health center f.r severe malaria (according to WHO criteria) between 1 January 2018 and 31 December 2021 was perf.rmed. Data collection was done through a questionnaire. Records, hospitalization records, and treatment records were the sources of.collection. Data entry and analysis were perf.rmed on Epi Inf. 7.2 and R. Results: A total of.481 children hospitalized with severe malaria were recruited. The highest number of.cases was recorded in 2018 (33.05%). In the f.ur years of.the study, peaks were always observed between October and November and the highest peak in November 2020 with 95 cases. The mean age was 65.64 months with a standard deviation of.29.28 months and a predominance of.male (53.43%). The majority of.people were admitted f.om the outpatient clinic (57.79%) and the rest (42.21%) on the recommendation of.a peripheral health post. All hospitalized patients had a positive RDT and/or a positive thick drop. However, the sharp decline at admission or during hospitalization was positive in 93.80% of.patients in our series, negative in 5.20% and not achieved in 1.00%. Seizures and severe anemia topped the list of.signs of.severity with 45.94% and 8.11%, respectively. In terms of.evolution, f.r all hospitalized patients, there were 81.29% recovery, 10.19% ref.rral to the Tambacounda regional hospital center f.r hospitalization, 4.99% death, 0.83% discharge and 2.70% unknown evolution.

This is a review of.the f.rst 10 coronary artery bypass surgeries perf.rmed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/f.ratio of.4:1. Cardiovascular risk f.ctors were mainly myocardial inf.rction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk f.ctors per patient. Angina was the main symptom (80%). The average time f.om presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of.2 lesions per patient, with 3-vessel involvement in 70% of.cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumf.ex artery (70%). On echocardiography, the mean Lef. ventricular ejection f.action (LVEf. was 59% [33% - 76%]. All patients underwent median sternotomy with bypass graf.ing. The average duration of.the cardiopulmonary bypass was 150 min [46 - 275 min];that of.aortic clamping, 120 min [43 - 232 min]. The graf.s used were internal thoracic artery (ITA) in 100% of.cases (80% on the lef. and 20% on the right), and the great saphenous vein (GSV) in 60% of.cases (50% on the lef. and 10 on the right). Double bypass was perf.rmed in 60% of.cases, single bypass in 30% and triple bypass in 10%. The bypasses were perf.rmed on the IVA (100%), the middle lateral of.the circumf.ex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of.stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of.the patients (90%), with a predominance of.inf.ctious and neurological complications. Overall operative mortality was 3%, all in intensive care.

Introduction. Hyperprolactinemia represents a supraphysiological secretion of.prolactin. In clinical practice, it is the most f.equently encountered anterior pituitary disorder. However, its real prevalence is little known in Af.ica. The purpose of.this study is to list all cases of.hyperprolactinemia over the past f.ur years and to make an inventory of.the various etiologies f.und and their management. Methodology. This is a cross-sectional descriptive study on the f.les of.patients who came f.r consultation in the internal medicine and endocrinology department with hyperprolactinemia retrospectively collected f.om January 2017 to December 2020. Included were patients f.llowed or whose the diagnosis of.hyperprolactinemia was established in endocrinological consultation during the study period. Results. This study recorded 26 cases of.hyperprolactinemia. The f.male sex represented 73.08% (sex ratio M/f.0.37) and the average age was 33.92 years. The 40 - 50 age group was the most represented with 30.77%. In women, galactorrhea accounted f.r 73.07%, amenorrhea 57.69% of.clinical pictures and inf.rtility 23.08%. In men, inf.rtility accounted f.r 7.69% of.presentations, gynecomastia 11.54% and erectile dysf.nction 15.38%. The duration of.evolution of.the signs was 4 months in 23.08% of.the patients. The mean prolactinemia was 702.58 ng/ml. CT was perf.rmed in 80.85% of.patients. The main etiologies were pituitary adenomas (77%). All our patients were treated with dopaminergic agonists. Cabergoline was prescribed in 77% of.patients. The evolution was f.vorable in 96.25% of.patients. Conclusion. Hyperprolactinemia is a pathology that exists in our regions. The main etiology remains pituitary adenomas and treatment with cabergoline.
