BACKGROUND: Multirow-detector helical CT (MDCT) allows faster Z-axis coverage and improves longitudinal re- solution to scan the entire liver. This study was to evaluate the value of multiphase hepatic CT scans using MDCT in diagnosing hypervascular hepatocellular carcinoma (HCC). METHODS: Multiphase hepatic CT scans in 40 patients were carried out with a Marconi Mx8000 MDCT scanner. The scans of early arterial phase (EAP), late arterial phase (LAP) and portal venous phase (PVP) were started at 21, 34 and 85 seconds after injection of contrast medium, re- spectively. The number of detected lesions was calculated in each phase. The density of the liver and tumor was great- er than 1 cm for HCC, and the density of the liver and tumor in each phase was statistically calculated. RESULTS: A total of 61 lesions were found in the 40 pa- tients , and lesions greater than 1 cm were seen in 47 cases. The density differences between the liver and tumor were statistically significant (P<0.05) at the LAP and EAP and between the LAP, EAP and PVP. In the 61 lesions, the de- tectability in the EAP, LAP and the double arterial phases (DAP) was 32%, 87%, and 94%, respectively. Significant difference was found between the LAP plus PVP and the EAP plus PVP; but no significant difference was observed between the DAP plus PVP and the LAP plus PVP. CONCLUSIONS: The utility of MDCT scan in the liver has optimized the protocol of arterial phase scan. MDCT is possible to scan the entire liver in a real arterial phase and it is very valuable in the detection of small HCC.

The fight against iron deficiency anemia in pregnant women is a public health priority, especially in sub-Saharan Africa. Spirulina is an alga very rich in iron, used as a dietary supplement. This research proposes to study its effect on the hemogloblobinaemia of pregnant women. This was a blind randomized cohort study with a supplemented group of spirulina (1500 mg/d) and a second supplemented with iron and folic acid supplementation (IFAS). Included in this study were pregnant women attending four health centers in the Dakar region, with pregnancy at 28th amenorrhea, agreeing to participate and not having complications or twin pregnancies. Follow-up of the two groups was identical throughout the study from the 28th week of amenorrhea to the 42nd postnatal day. The study was conducted among 920 women, evenly distributed among the groups. IFAS allowed a statistically significant increase in hemoglobinemia with an average gain of 0.3 g/dl between the 28th and 32nd weeks of amenorrhea (p = 0.022) and 0.2 g/dl between the 28th week and the delivery (p = 0.043). Spirulina supplementation showed statistically higher gains than those observed with IFAS. These gains were 0.48 g/dl between the 28th and 32nd weeks of amenorrhea and 0.36 g/dl between the 28th week and the delivery, with p values less than 0.001. Spirulina, more accessible to developing countries, is a good option to strengthen the arsenal of iron deficiency anemia control, and therefore maternal mortality.

The anemia by iron deficiency is a public health problem. To palliate the multiple maternal and fetal consequences, the WHO recommends the iron supplementation during at least 90 days to all pregnant women. The goal of our study is to study the determinants of this consumption in the Kolda area (Senegal). It’s the analytical cross-sectional study referred. We use the survey by clusters with 2 levels and it’s about all of the women who gave birth in Kolda area between February 2013 and January 2014. The dependent variable was iron consumption during at least 90 days and the independents variables were grouped on personal factors, knowledge and practices. Data were collected during a personal interview face to face. We used logistic regression to identify the determinants of this consumption. The average age of women surveyed in 1442 was 25.5 years. They had knowledge of iron consumption (93%) and the number of antennal consultation (ANC) (66%). The prevalence of pregnant women who consumed iron at least for 90 days was 51%. The factors associated with consumption were schooling (ORa = 2.49 [1.54 - 4.03]), health awareness (ORa = 1.61 [1.25 to 2.07]), knowledge about number of ANC (ORa = 1.54 [1.18 - 2.00]), councils on the benefits of iron (ORa = 2.66 [1.77 - 4.00]), the household wealth index (ORa = 1.83 [1.04 to 3.19]), number of ANC (ORa = 2.05 [1.56 - 2.69]), age pregnancy on the first ANC (ORa = 2 [1.47 - 2.7]) and iron prescription (ORa = 1.64 [1.25 - 2.16]). The prevalence of iron consumption during at least 90 days is low in Kolda area (51%);however, its determinants are identified;we can solve the problem by increasing communicate more about iron supplementation and antenatal consultation.

Advances in Sexual Medicine 2019年第3期9卷 29-39页

Introduction: In Senegal, adolescents aged 10 to 19 years represent 22.9% of the total population. The unmet need for contraception in this part of the population remains high despite the health interventions implemented to promote their sexual health. The aim of this study is to analyze the practice of modern contraception in schools in Dakar high schools in Senegal during the year 2018. Methods: A cross-sectional study was conducted in high schools and colleges in Dakar from March 1 to April 30, 2018. This study involved 452 students. This was a self-administration of the questionnaires. After univaried and bivaried analyses, a multivariate logistic analysis identified the factors associated with students’ use of modern contraception. Results: The prevalence of modern contraceptive use among students is 8.84%. Factors associated with the use of modern contraceptive methods among students were age over 18 years (AR: 4.7, 95% CI [1.02 - 22.5]), male sex (AR: 27.8, 95% CI [6.8 - 100.0]), secondary school level (AR: 10.6, 95% CI [2.1 - 53.0]), access to a youth socio-educational home (AR: 3.9, 95% CI [1.1 - 14.9]) and having a child (AR: 25.6, 95% CI [2.2 - 100.0]). Conclusion: Our results concluded that modern contraceptive needs were better met among older male students, those who had an unfortunate experience of unwanted pregnancy and those attending school’s youth socio-educational homes. This suggests shortcomings in the promotion of sexual health among younger students, particularly those in the secondary grades.

针对目前有些企业在深化体制改革，转换经营机制后仍存在以改代管，以转代管，忽视企业管理的片面做法，指出转换经营机制，建立现代企业制度是增强企业活力的必要条件，实施科学管理则是企业生存和发展的基础。企业管理必须随着体制改革的深入发展而不断创新，加强管理必须从更新观念，完善法人治理结构，大力培养管理人才，建立以人为本的激励制度，建立目标成本管理制度，吸收和引进现代科学管理方法，以及改革投资管理制度等方面着手。
