Dengue fever is a mosquito-borne disease caused by four related but antigenically distinct dengue viruses. In the last half-century, the prevalence of dengue fever has increased dramatically (up to 30%) worldwide, especially in Sub-Saharan Africa. In Burkina Faso, the last dengue epidemic occurred in 2016, and the epidemiological situation is still poorly documented at the national level. Therefore, the present study aimed to conduct a sentinel seroepidemiology of suspected dengue virus infections from 2017 to 2020 at Charles de Gaulle University Pediatric Hospital Center of Ouagadougou. This investigation was designed to be a descriptive and analytical study. Patients with suspected cases of dengue fever were recruited from January 2017 to December 2020 during general medicine consultation and referred to Charles de Gaulle University Pediatric Hospital Center of Ouagadougou for the serological diagnosis of dengue. Venous blood was collected in dry or EDTA tubes and tested for DENV NS1 antigen, anti-dengue IgM, and anti-dengue IgG using SD Bioline Dengue Duo Rapid Detection Kit (Standard Diagnostic Inc., Korea). A total of 3400 blood samples from clinically suspected dengue cases were analyzed, of which 1784 (52.5%) were males, and 1616 (47.5%) were females. Among the 3400 patients included in the study, 661 (19.4%) were tested at least positive for NS1 antigen, anti-dengue IgM or anti-IgG. Among them, individuals positive for IgG suggesting past dengue virus infection were found in more than a third of 262 (7.7%) of the cases. Approximately, 80.0% (2705/3400) dengue suspected cases and 85.5% (341/399) early or primary dengue infections were recorded in the last four months of the study (September to December 2020), with a peak in mid-October and mid-November. There was no statistically significant difference in seroprevalence between males and females (p = 0.7), but an increasing seropositivity trend with age, from 11.6% for the patient under 5 years group to 39.7%

Anti program death-1/anti program death-ligand 1 in digestive cancers

World Journal of Gastrointestinal Oncology 2015年第8期7卷 95-101页

Human tumors tend to activate the immune system regulatory checkpoints as a means of escaping immunosurveillance. For instance, interaction between program death-1(PD-1) and program death-ligand 1(PD-L1) will lead the activated T cell to a state of anergy. PD-L1 is upregulated on a wide range of cancer cells. Anti-PD-1 and anti-PD-L1 monoclonal antibodies(m Abs), called immune checkpoint inhibitors(ICIs), have consequently been designed to restore T cell activity. Accumulating data are in favor of an association between PD-L1 expression in tumors and response to treatment. A PD-L1 expression is present in 30% to 50% of digestive cancers. Multiple anti-PD-1(nivolumab, pembrolizumab) and anti-PD-L1 m Abs(MPDL3280A, Medi4736) are under evaluation in digestive cancers. Preliminary results in metastatic gastric cancer with pembrolizumab are highly promising and phase Ⅱ will start soon. In metastatic colorectal cancer(CRC), a phase Ⅲ trial of MPDL3280 A as maintenance therapy will shortly be initiated. Trials are also ongoing in metastatic CRC with high immune T cell infiltration(i.e., microsatellite instability). Major challenges are ahead in order to determine how, when and for which patients we should use these ICIs. New radiologic criteria to evaluate tumor response to ICIs are awaiting prospective validation. The optimal therapeutic sequence and association with cytotoxic chemotherapy needs to be established. Finally, biomarker identification will be crucial to selection ofpatients likely to benefit from ICIs.

3D numerical simulation of seagrass movement under waves and currents with GPUSPH

The current study tries a new approach to simulating interactions between waves and seagrass through Smoothed Particle Hydrodynamics(SPH). In this model, the plants are defined as a solid that respects Hooke’s law, and are assumed to have direct interaction with the fluid. Given the characteristics of the SPH method, especially in terms of computational time, the dimensions of the simulations were *** first goal of the current study was to optimize the approach to avoid reaching certain limits such as the rupture of the simulated plant. Plant movements under waves and/or currents have been studied by several authors in various in-situ, physical, and numerical experiments concerning various vegetation species, thus proving that plant movements can be successfully reproduced by SPH 2D/3D. Manning’s roughness coefficient, n, was calculated to confirm that the results were in accordance with what had been measured in flume studies. Even though there is still room for improvement, it is shown that this method can be used to estimate Manning’s coefficient for coastal vegetation(seagrass and saltmarsh vegetation) and to greatly improve the modeling and forecasting of coastal erosion and storm surge risks by including the effects of vegetation in integrated models.

In low income countries, severe acute malnutrition remains a major problem for HIV-infected children and an important risk factor for mortality. This study aims to analyze HIV impact on mortality rate and nutritional recovery among severely malnourished HIV/AIDS uninfected and infected children. This was a retrospective cohort study conducted from data of 521 hospitalized severely malnourished children. We used Pearson’s Chi square test to compare proportions;and Student’s independent t-test to compare means;general linear model to analyze repeated measurements. We used mortality relative risk with confidence interval (CI 95%), Kaplan-Meir survival curves and Cox proportional hazard models to analyze the HIV impact on mortality rate. Case fatality rate differed significantly from SAM HIV uninfected (10.7%) and HIV infected children (39.7%), p elative risk was 3.71, 95% IC [2.51 - 5.47] for HIV infected children. Kaplan-Meir survival curves differed significantly between the two groups, (p Log Rank elative risk of HIV infected children was 4.27, CI: 2.55 - 7.15, p elative risk was 3.71 times higher for HIV infected children. Multiples infections and metabolic complications have synergism on death occurrence in sever acute malnutrition;when associated to HIV infection, case fatality rate increases many times. Weight gain and anthropometrics index evolution were very slow for SAM HIV infected children, and specific diet may be needed for more nutritional recovery.

Micronutrient deficiencies, in HIV/AIDS infected children, are common and associated with disease progression and increased mortality. There is no evidence to support specific recommendation for in-patient treatment of severely malnourished HIV/AID infected children. We analyzed the impact of daily oral multivitamin and mineral supplementation on nutritional status and on mortality rate, of severely malnourished HIV/AIDS infected infants, hospitalized in a feeding therapeutic center. Children were randomized at admission in one of the two treatment groups: WHO standard group or additional dose group. The trial has been approved by the national health research ethics committee. Case fatality rate was high in each group. There was no difference in mortality rate between WHO standard group (mortality rate = 16.9%) and “additional dose” group (mortality rate = 17.6%). Kaplan Meir survival curves did not differ between the two groups, (p Log Rank = 0.87). During the inpatient follow-up, the median weight gain (g/kg/d) was low in groups and did not differ between WHO standard group (8.88g/kg/d Min = 4.70, Max = 17.23) and “additional dose” group (10.50g/kg/d, Min = 3.29 Max = 17.81) (Wilcoxon test p-value = 0.10). From admission to discharge, anthropometric Z-scores means evolution did not differ between the two groups: WHZ (p = 0.74), WAZ (p = 0.79) and MUAC (p = 0.73). In this randomized trial among severely malnourished HIV/AIDS infected children, we found no evidence that the provision of daily additional micro-nutrient dose during inpatient treatment, compared to WHO standard, improves nutritional status or reduces case fatality rate. Rigorous malnutrition inpatient treatments, including effective HIV/AIDS management, improve nutritional status of severely mal-nourished HIV infected children.

Glucose-6-phosphate dehydrogenase deficiency is the most common enzymopathy worldwide. The precise prevalence of G6PD is unknown in Burkina Faso. The objective of the study was to describe the difficulties to diagnose this disease at the Souro Sanou University hospital (CHUSS) in Bobo-Dioulasso. It involved five patients comprising one child with homozygous SS sickle cell disease, one adolescent screened following a family investigation, and three adults including a man and two women. Blood smear stained with May Grunwald Giemsa was performed to look for specific signs of G6PD-deficient red blood cell and brilliant cresyl Blue for Heinz Bodies. A microscope Olympus BX53 equipped with a Camera (XC10) and connected to a computer was used to read blood smears and capture images. Genes sequencing by Sanger method were performed in a specialized laboratory in molecular genetics. For each analysis, the protocol and instructions of the equipment and reagent manufacturer were applied. Of the five patients, three had anemia and only one had hyperreticulocytosis. Two patients had biological signs of hemolysis and one patient had an elevated CRP. Blood smear stained with MGG and cresyl blue showed specific signs of G6PD-deficient red blood cells and Heinz bodies in all patients. Biochemical analysis and molecular typing confirmed G6PD deficiency. The presence of G6PD-deficient red blood cells in the blood smear guides the diagnosis of G6PD deficiency. The diagnosis is biochemical and is based on the combined measurement of G6PD plus pyruvate kinase and/or hexokinase.
