Introduction: Urogenital prolapse is the descent of one or more elements of the abdominal-pelvic contents into the vaginal cavity. The anterior, middle and posterior anatomical compartments may be involved giving rise to several types of genital prolapse. However, there are various therapeutic modalities ranging from observational procedures to surgery. In Yaounde, urogenital prolapse appears to be a rare clinical entity, and its treatment has not been clearly stated. There is limited data about this subject in our context. Our aim was to study the clinical and therapeutic aspects of urogenital prolapse in Yaounde. Methods: We conducted a descriptive cross-sectional study with retrospective data collection at the Yaounde Gynaecological Obstetric and Pediatric Hospital (YGOPH) and the Yaounde Central Hospital (YCH) over a period of 05 months (from February 2022 to June 2022). All women aged ≥30 years and all women with documented urogenital prolapse admitted to the maternity and urology departments of these two health facilities were included. Data were collected using a structured questionnaire. Data was analyzed using IBM SPSS (statistical package for social sciences) software version 23.0 and the data were reported as mean, standard deviation, frequencies and percentages. Results: A total of 50 patients were recruited;the mean age was 45.8 ± 17 years. The age range was from 21 to 72 years. Majority of the patients were aged more than 55 years (32%). Most of the patients attended primary education (48%). Forty percent of the patients were housewives. The majority of the patients were from West Cameroon (26%). The most common reason for consultation was pelvic heaviness (54%). The most prevalent clinical sign was cystocele (56%), followed by hysterocele (54%). According to the Baden Walker classification, one-third of the patients were classified as first degree (36%). More than half (58%) of patients had the condition located at the first stage.

The accumulation of growth-promoting antibiotic residues in animal products and the resistance developed by bacteria in poultry farms has led to a search for natural compounds derived from plants. This study was designed to promote the production performance of broiler chickens using fresh Cupressus sempervirens leaves infusion. Fresh Cupressus sempervirens leaves were harvested, washed, chopped and ground to a paste using a blender and fermented for three days in a closed container at a rate of 500 g/L of water. The solution obtained was filtered and added at the rate of 2, 4, 6, 8 and 10 ml/L of drinking water. The chickens fed on the graded level of the solution were compared to a control ration without an additive and positive control group supplemented with 1 g antibiotic/kg feed. At the finisher phase and throughout the study period, water intake increased significantly (P 0.05) affected by the inclusion of Cupressus sempervirens infusion. Haematological parameters significantly (P < 0.05) increase independently of the rate of incorporation of the infusion into the drinking water, with the exception of RBCs, MCHT and PCT. Serum content in total protein, globulins, LDL cholesterol and triglycerides were significantly (P < 0.05) high with 8 and 10 ml Cupressus sempervirens infusion/litre drinking water as compared to all other treatments. AST, ALT, urea, creatine, albumin, total cholesterol and HDL-cholesterol were not significantly affected. The lactic acid bacteria load increased significantly (P E. coli and salmonella counts decreased significantly (P < 0.05)

Introduction: COVID-19, an emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), typically presents with mild clinical manifestations in pediatric populations. As in many other regions of the Democratic Republic of the Congo (DRC), the COVID-19 pandemic affected children in Haut-Uélé, a province bordering South Sudan and Uganda. This study aimed to describe the epidemiological profile of COVID-19 in pediatric population in this area. Materials and Methods: This descriptive cross-sectional study was conducted over a 6-month period from August 1, 2021 to February 7, 2022. It included all patients aged 0 to 19 years with confirmed COVID-19 using RT-PCR and managed at the COVID-19 Treatment Centers (CTCO) in ISIRO and WATSA. Data were collected from patient records supplemented by the dataset from the service of Health Information System (SNIS) and the Epidemiological Surveillance Commission of the Provincial Health Division (DPS). Epidemiological and clinical profiles were analyzed. All statistical analyses were performed using SPSS software, Version 18. Results: During the 4th wave of the pandemic, 5 out of 13 health zones in Haut-Uélé province were affected, with a total of 569 recorded cases;45 of them were children aged 0 to 19 years (7.9%). Asymptomatic cases accounted for 33.3% (15 cases). The mean age was 9.88 ± 5.49 years, with the most affected age group being 10 - 14 years (44.45%). There was a predominance of males (73.3%), with a male-to-female sex ratio of 2.75. Half of the patients (53.3%) were from Watsa Health Zone. A seasonal peak was observed between December and January. Comorbidities were present in 10% of infected patients, and nearly half of participants were contacts of infected individuals. The primary reasons for admission were fever (66.66%), followed by rhinorrhea (57.77%) and cough (31.11%). All patients responded favorably to treatment. Conclusion: The proportion of pediatric COVID-19 cases at t

Objective: The COVID-19 pandemic has highlighted the need to strengthen diagnosis and genomic surveillance capacities. In 2021, Central African managed five waves of COVID-19 by integrating genomic surveillance into their health monitoring system. This study sought to report surveillance data from the National Laboratory of Clinical Biology and Public Health and describe the circulation of SARS-CoV-2 variants. Materials and Methods: This retrospective, descriptive observational study spans three years, from April 2020 to November 2023. It was conducted on a population of consenting volunteers from across the Central African Republic, who were tested using RT-PCR on nasopharyngeal samples. Data with sufficient information were obtained from the National Laboratory of Clinical Biology and Public Health (LNBCSP) databases. Sequencing was largely carried out at the National Institute of Biomedical Research (INRB) in Kinshasa until May 2023, and subsequently at the LNBCSP. Results and Discussion: Out of 97,864 RT-PCR tests performed, 9,764 were positive, resulting in a prevalence of 9.98%. The average age of the patients was 39.97 years ± 13.76, and the male-to-female sex ratio was 2.12. RT-PCR test positivity was significantly associated with age (p = 0.001), sex (p = 0.013) and clinical manifestations. Ten variants circulated during the five recorded waves, with Omicron (B.1.1.529), Delta (B.1.617.2) variants being predominant. Notably, the B.1.620 and B.640 variants were prominent during the second wave. Conclusion: This retrospective study provides key insights into the COVID-19 pandemic in the CAR. It identifies risk factors and details the circulation of various SARS-CoV-2 variants. Enhancing national genomic surveillance capacities would enable the country to better respond to future pandemic challenges.

Density Results in Sobolev Spaces Whose Elements Vanish on a Part of the Boundary

引用

Chinese Annals of Mathematics,Series B 2011年第6期32卷 823-846页

作者： jean-marie Emmanuel BERNARD Laboratoire Analyse et Probabitilités Université d'Evry val d'Essonne23 Boulevard de France91037 EVRYFrance

This paper is devoted to the study of the subspace of Wm＇＂ of functions that vanish on a part γ0 of the boundary. The author gives a crucial estimate of the Poincare constant in balls centered on the boundary of γ0. Then, the convolution-translation method, a variant of the standard mollifier technique, can be used to prove the density of smooth functions that vanish in a neighborhood of γ0, in this subspace. The result is first proved for m = 1, then generalized to the case where m 〉 1, in any dimension, in the framework of Lipschitz-continuous domain. However, as may be expected, it is needed to make additional assumptions on the boundary of γ0, namely that it is locally the graph of some Lipschitz-continuous function.
