Objectives: To specify the epidemiological and clinical profile of the patients, to determine the methods of management and to evaluate the maternal and perinatal prognosis in the association of arterial hypertension and pregnancy (HTA) at the Institute of Social hygiene of Dakar. Material and Methods: This was a retrospective, descriptive and analytical study on the management of the association of hypertension and pregnancy in the maternity ward of the Institute of Social hygiene of Dakar between January 1st, 2019 and on December 31st, 2020. Results: During the study period, we recorded 326 cases of hypertension associated with pregnancy among the 4290 pregnant women, i.e. a frequency of 7.6%. The epidemiological profile of the patients was that of a woman with an average age of 29, nulliparous (48.2%), married (99.1%), at a low socioeconomic level (61.3%) and with a personal history preeclampsia (14.4%). Most patients (83.1%) were evacuated or referred with pre-ec- lampsia as the main reason (40.8%). The average gestational age was 37 weeks of amenorrhea (SA) with extremes of 20 SA 6 days and 41 SA 5 days. Term pregnancies were the most represented (76.7%). Prenatal follow-up (CPN) was carried out in 319 patients (97.8%) with an average number of CPN of 3 and extremes of 1 and 9. Severe diastolic and severe systolic hypertension concerned respectively 19.3% and 16, 9% of patients. One hundred and eighty patients (55.2%) presented with oliguria. Strip albuminuria was performed in 235 patients (72.1%). It found 3 or more crosses in 38.3% of cases. We recorded 53 cases of anemia (16.3%), 16 cases of significant proteinuria (5%), hepatic cytolysis in 22 patients (6.7%), thrombocytopenia in 37 patients (11.3%), and 43 cases of hyperuricaemia (13.2%). Obstetric ultrasound found 36 cases of severe oligohydramnios (11%), 8 twin pregnancies (2.4%) and an umbilical Doppler anomaly in 10 patients (3.1%). Pre-eclampsia was the most common clinical form

Objective: Determine the frequency of evacuations, specify the epidemiological and clinical characteristics of the evacuees, evaluate the data of the evacuation, the management and the maternal-fetal prognosis. Methods: Prospective and descriptive retrospective study concerning obstetrical evacuations received at the maternity ward of the Hospital of the Institute of Social hygiene in Dakar between January 1 and December 31, 2020, i.e. a period of 12 months. Results: During the study period, we collected 1156 evacuees out of a total of 3507 patients treated in the Service, i.e. a frequency of 33%. The average age of the patients was 27.07 years with extremes of 14 and 46 years. Patients aged between 20 and 29 were the most represented (51.73%). The average parity was 1.6 with extremes of 0 and 10 pares. The nulliparous (46.37%) were the majority. The majority of evacuated patients (99.6%) resided in the Dakar region, including 58% in the suburbs and 42% in the city center. The patients received had performed an average of 3 prenatal consultations with extremes ranging from 0 to 9 CPN. They most often came from health centers (55.05%) or hospitals (29.09%). The reasons for evacuations were dominated by dystocia (21.54%) followed by premature rupture of membranes (17.21%) and premature deliveries (16.35%). On admission, only 176 patients (15.2%) had an evacuation sheet. Patients transited on average through two health structures (extremes ranging from 0 to 7 structures) before reaching the reception structure. The evacuation was most often done with a private vehicle on the patient’s own means (91.96%). The outcome of the evacuees was most often vaginal delivery or hospitalization (72.79%). The majority of patients (99.4%) had evolved favorably but we deplore one maternal death (0.09%) linked to a late puerperal infection. We recorded 74 perinatal deaths and 1041 live births, i.e. a stillbirth rate of 71.1‰ live births. The causes of death were dominated by prematurit

Introduction: The human immunodeficiency virus (HIV) is a pandemic of concern to the World Health Organization. It is all the more worrisome because if not properly managed, it can be responsible for several complications, including abnormal blood counts. These abnormalities may also be related to treatment. Objectives: The main objective of this study is to show that adequate antiretroviral therapy can correct various abnormalities exerted by HIV on patients’ blood counts. The specific objective is to determine all the abnormalities we can see in blood count before and during HIV treatment. Materials and Methods: Our study was conducted in the hematology laboratory and the dermatology departments of the Aristide Le Dantec Hospital and the Institute of Social hygiene. It took place from December 2009 to October 2011. It is a retrospective descriptive and analytical study involving HIV-positive patients (HIV 1 and 2) and under antiretroviral treatment (at least six months of treatment). We included 110 patients in the study. Blood counts were performed at the hematology laboratory of the Aristide le Dantec hospital using a KX21 automaton. Each patient received three blood counts during the first six months of treatment (M0, M3 and M6). A univariate analysis was performed to determine the profile of the abnormalities of the blood count and the chi 2 test was used and a threshold of p 0.05 was considered significant. Results: The mean age of the patients was 38.6 ± 8.6 years (extremes of 18 and 64 years) with a sex ratio of 0.42 (77 females and 33 males). The prevalence of anemia was 80% (n = 88) at M0, 53, 63% at M3 (n = 59), and 38.20% at M6 (n = 42) (p = 0.02). We noted a favorable evolution with treatment. For the other abnormalities, the evolution was favorable for leukopenia (p = 0.011) and thrombocytopenia (p = 0.007). Conclusion: Our study showed a correction of blood count abnormalities in PLHIV with antiretroviral treatment.

Objective To explore the effect of soy isoflavone on obesity in the light of hypothalamus and peripheral orexigenic gene regulation. Methods Fifty-four female rats were randomly assigned to 6 groups： one sham-operated group （SHAM）, one ovariectomized （OVX） control group, three OVX groups fed with 400 ppm （L-SI）, 1 200 ppm （M-SI） and 3 600 ppm （H-SI） isoflavone respectively, and one OVX group receiving 0.45 ppm diethylstilbestrol （EC）. All rats were allowed to take high-fat diet for 4 weeks. Some neuropeptides were measured by RT-PCR. These neuropeptides included NPY, pro-opiomelanocortin （POMC）, cocaine and amphetamine regulated transcript （CART）, orexin, melanin-concentrating hormone （MCH）, ting hormone precursor （P-MCH）, ghrelin, and leptin. Results Compared with the OVX control group, the body weight and food intake in the H-S1 group were reduced significantly and there was a significant dose-dependent manner in the 3 isoflavone groups. The results of RT-PCR showed that the NPY level in the 3 isoflavone groups was significantly increased and the POMC/CART gene expression decreased significantly in rats＇ hypothalamus compared with that in the OVX control group. However, the expression of orexin, MCH and P-MCH had no change. The peripheral grelin mRNA expression was higher in the 3 isoflavone groups, while leptin gene expression in the fat was not consistent. Conclusions This research showed that isoflavone could prevent obesity induced by high-fat diet and ovariectomy through regulating hypothalamus and peripheral orexigenic gene expressions associated with food intake.

作者： J.O.KAMGANG M.NAITALI J.-M.HERRY M.-N.BELLON-FONTAINE J.-L.BRISSET R.BRIANDET Laboratory of Interfacial Electrochemistry and Analytical Chemistry University of Rouen INRA(National Institute for Agricultural Research) UMR 763 Bio-adhesion and Hygiene of Materials AgroParisTech UMR 763 Bio-adhesion and Hygiene of Materials AgroParisTech UMR763 Bio-adhesion and Hygiene of Materials

This study addressed the effects of treatment with gliding discharge plasma on the surface properties of solid materials, as well as the consequences concerning adherence of a model bacterium. As evaluated by contact angles with selected liquids, plasma treatment caused an increase in surface hydrophilicity and in the Lewis acid-base components of the surface energy of all materials tested. These modifications were more marked for low density polyethylene and stainless steel than for polytetrafiuoroethylene. After treatment, the hydrophilicity of the materials remained relatively stable for at least 20 days. Moreover, analysis of the topography of the materials by atomic force microscopy revealed that the roughness of both polymers was reduced by glidarc plasma treatment. As a result of all these modifications, solid substrates were activated towards micro-organisms and the adherence of S. epidermidis, a negatively charged Lewis-base and mildly hydrophilic strain selected as the model, was increased in almost all the cases tested.

作者： JIN LIU JIAN-QUAN WU JI-JUN YANG JING-YU WEI WEI-NA GAO CHANG-JIANG GUO Institute of hygiene and Environmental Medicine Tianjin 300050 China

Objective To explore metabolic changes after acute hypoxia and modulating effect of vitamins B1, B2, and PP supplementation in mice exposed to acute hypoxia. Methods Fifty male Kunming mice were randomly divided into 5 groups： normal, acute hypoxia, acute hypoxia with 2, 4 and 8 time- vitamins B1, B2, and PP supplementation . All mice were fed with corresponding diets for two weeks and then were exposed to a simulated altitude of 6 000 meters for 8 h, except for the normal group. Nuclear magnetic resonance analysis was used to identify the changes of serum metabolic profiles. Results There were significant changes in some serum metabolites under induced acute hypoxia, essentially relative increase in the concentrations of lactate, sugar and lipids and decrease in ethanol. The serum levels of choline, succinate, taurine, alanine, and glutamine also increased and phosphocholine decreased in the acute hypoxia group. After vitamins B1, B2, and PP supplementation, all these metabolic changes gradually recovered. Conclusion Significant changes in serum metabolic profile were observed by metabolomics in mice exposed to acute hypoxia, and vitamins B1, B2, and PP supplementation proved to be beneficial to improving some metabolic pathways. It is suggested that the dietary intakes of vitamins B1, B2, and PP should be increased under hypoxia condition.
