Based on 2022 and 2023 hydrometric data and satellite images (Sentinel 2022, SPOT 2010), this study aims to present the Nokoué Lake and its channels’ re-cent hydromorphological characteristics. Integrating flow, tributary morphology, and topography data determined specific power values along the axes studied. The values obtained range from 2.69 to 12.92 W/m2 for Ouémé River and 2.46 to 10.99 W/m2 for Sô River. The resulting water erosion on banks and bottoms is of linear, areolar, or gully and claw types. Lake bathymetry varies from -0.5 to -2.6 m (low flow period) and -1 to -4 m;in the Ouémé, Sô, and Totchè rivers, it varies from -5 m to -7 m, reaching -10 m at the cotonou channel entrance (flood period). Bathymetric profiles reveal varied “U”, “V” and “Intermediate” bottom morphologies, influenced by erosion/sedimentation processes and human activities. The flow facies identified are lentic in the northern tributaries and lotic in the cotonou and Totchè canals. Spatial analysis identified nine (09) thematic classes. In 2022, the surface area of the water body has increased from 274 km2 at low water to 280 km2 at high water, whereas in 2010 (a recent year of exceptional flooding), the surface area was 270 km2 at low water and 277 km2 at high water. Significant changes in land use are observed between 2010 and 2022. The floodplain area decreased slightly, from 421 km2 in 2010 (year of exceptional flooding) to 419 km2 in 2022. The evolution of land use shows a progressive expansion of the urban environment to the detriment of the natural environment. In the medium to long term, this trend could threaten the hydromorphological balance and even the existence of this important lagoon ecosystem.

Introduction: Acute appendicitis represents an urgent surgical condition, requiring the removal of the vermiform appendix. Laparoscopy is the standard surgical approach. This study aimed to outline the epidemiological, clinical, therapeutic, and outcome characteristics of patients undergoing laparoscopic surgery for acute appendicitis. Patients and Methods: A descriptive, retrospective analysis was carried out in the Emergency and Digestive Surgery departments of the University Hospital center of Brazzaville, spanning two years from January 1, 2021, to December 31, 2022. The study included all patients who underwent laparoscopic surgery for non-complicated acute appendicitis. Results: The study included 12 cases of non-complicated acute appendicitis treated with urgent laparoscopy. The mean age of the patients was 37 ± 8.9 years, with a sex ratio of 0.7. The predominant symptom leading to consultation was pain in the right iliac fossa, with an average time to consultation of 6.4 ± 5.7 hours. Patient histories included diabetes in one case, obesity in two cases, and one case of prior abdominoplasty. During surgery, a phlegmonous appendix was observed in nine patients. The average duration of hospital stay was 3.6 ± 1.3 days, with all patients experiencing uncomplicated recoveries. conclusion: The practice of emergency laparoscopic appendectomy is still relatively infrequent in our setting and presents an ongoing challenge.

New clinical approaches are imperative beyond the widely adopted National comprehensive cancer Network (NccN) guidelines, utilized by prominent cancer institutions. cancer is the leading cause of death among individuals younger than 85 years within the United States. Despite significant technological advances, including the expenditure of hundreds of billions, treatment outcomes and overall survival have not notably improved for most types of advanced cancer over the last several decades. Over the past 24 years, Envita Medical centers has pioneered a unique form of personalized treatment approach for late-stage and refractory cancer patients, introducing groundbreaking innovations in the field. Our integrated algorithm utilizes advanced genomics, transcriptomics, and highly tailored immunotherapy, resulting in remarkable outcome improvements. This study presents Envita’s innovative personalized treatment algorithms and examines the response outcomes of 199 late-stage cancer patients treated at Envita Medical centers over a two-year period. compared to standard of care and palliative chemotherapy, Envita’s treatment demonstrated a remarkable 35-fold improvement in overall response rates (Figure 1). Moreover, 88% of the patients, the majority presenting with Stage 3 or 4 cancer, experienced a 43-fold improvement in quality of life with minimal side effects, as compared to standard of care chemotherapy and palliative care. This revolutionary success is attributed to Envita’s personalized therapeutic algorithms, which incorporate customized immunotherapy. Envita’s precision care approach has also achieved a 100% better response rate compared to over 65 global chemotherapy clinical trials with more than 2700 patients. The results from this study suggest that a wider utilization of Envita’s personalized approach can significantly benefit patients with late-stage and refractory cancer.

Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital center of Brazzaville.
