Abstract
Background "Cest la Vie!" (CLV) is a serial drama that entertains, educates, and promotes positive health behaviors and social change for West African audiences. The purpose of this study was to evaluate if watching the CLV Season 2 series online had an impact on people's health knowledge, attitudes, and norms, focusing on populations in francophone West Africa. Methods Between July 2019 and October 2019, viewers of CLV and non-viewers were recruited from Facebook and YouTube. We conducted an online longitudinal cohort study that assessed changes in health knowledge, attitudes, and norms (KAN) between these groups. Participants completed a baseline survey prior to the online airing and up to three follow-up surveys corresponding to specific health stories in the series, including sexual violence, emergency contraception, and female circumcision. We used descriptive statistics to describe viewers and non-viewers, and an item response theory (IRT) analysis to identify the effect of viewing CLV on overall KAN. Results A total of 1674 respondents participated in the study. One in four participants (23%, n = 388) had seen one of the three storylines from CLV Season 2 (ie, CLV viewers). At follow-up, viewers were more likely than non-viewers to know when to correctly use emergency contraception (P < 0.001) and to believe that the practice of female circumcision should end (P = 0.001). Compared to people who did not see CLV, viewers of the series had 26% greater odds of answering pro-health responses at follow-up about sexual assault, emergency contraception, and female circumcision. Further, the level of engagement with specific storylines was associated with a differential impact on overall outcome questions. Conclusions As internet access continues to grow across the globe and health education materials are created and adapted for new media environments, our study provides a novel approach to examining the impact of online entertainment-education content on health knowledge, attitudes, and norms.

Abstract
BACKGROUND Assessing hemodynamic status in preterm newborns is an essential task, as many studies have shown increased morbidity when hemodynamic parameters are abnormal. Although oscillometric monitoring of arterial blood pressure (BP) is widely used due to its simplicity and lack of side effects, these values are not always correlated with microcirculation and oxygen delivery. OBJECTIVES This review focuses on different tools for the assessment of hemodynamic status in preterm newborns. These include the measurement of clinical (BP, capillary refill time and urinary output (UO)) or biological parameters (lactate analysis), functional echocardiography, and near-infrared spectroscopy (NIRS). We describe the concepts and techniques involved in these tools in detail, and examine the interest and limitations of each type of assessment. CONCLUSIONS This review highlights the complementarities between the different parameters used to assess hemodynamic status in preterm newborns during the first week of life. The analysis of arterial BP measured by oscillometric monitoring must take into account other clinical data, in particular capillary refill time and UO, and biological data such as lactate levels. Echocardiography improves noninvasive hemodynamic management in newborns but requires specific training. In contrast, NIRS may be useful in monitoring the clinical course of infants at risk of, or presenting with, hypotension. It holds the potential for early and noninvasive identification of silent hypoperfusion in critically ill preterm infants. However, more data are needed to confirm the usefulness of this promising tool in significantly changing the outcome of these infants.

Abstract
Lower- and middle-income countries (LMICs) are experiencing rapid changes in access to and use of new internet and digital media technologies. The purpose of this study was to better understand how younger audiences are navigating traditional and newer forms of media technologies, with particular emphasis on the skills and competencies needed to obtain, evaluate and apply health-related information, also defined as health and media literacy. Sixteen focus group discussions were conducted throughout Senegal in September 2012 with youth aged 15-25. Using an iterative coding process based on grounded theory, four themes emerged related to media use for health information among Senegalese youth. They include the following: (i) media utilization; (ii) barriers and conflicts regarding media utilization; (iii) uses and gratifications and (iv) health and media literacy. Findings suggest that Senegalese youth use a heterogeneous mix of media platforms (i.e. television, radio, internet) and utilization often occurs with family members or friends. Additionally, the need for entertainment, information and connectedness inform media use, mostly concerning sexual and reproductive health information. Importantly, tensions arise as youth balance innovative and interactive technologies with traditional and conservative values, particularly concerning ethical and privacy concerns. Findings support the use of multipronged intervention approaches that leverage both new media, as well as traditional media strategies, and that also address lack of health and media literacy in this population. Implementing health-related interventions across multiple media platforms provides an opportunity to create an integrated, as opposed to a disparate, user experience.

Abstract
This evaluation study examines the effectiveness of a peer-led technology-focused HIV prevention program targeting in-school youth in Dakar, Senegal. A quasi-experimental design was used to examine differences in knowledge, attitudes, and behavioral intentions related to HIV testing among students at three intervention schools and a comparison school. Findings at the school level vary; however, results suggest that students exposed to intervention activities had a 1.5 greater odds of intending to get HIV tested compared with students not exposed to the program. As access to and use of digital technologies continue to increase throughout parts of sub-Saharan Africa, programs will continue to leverage this medium to diffuse effective health education and promotion messages for intervention.

Abstract
PU.1, a transcription factor of the ETS family, plays a pivotal role in normal hematopoiesis, and particularly in myeloid differentiation. Altered PU.1 function is possibly implicated in leukemogenesis, as PU.1 gene mutations were identified in some patients with acute myeloid leukemia (AML) and as several oncogenic products (AML1-ETO, promyelocytic leukemia-retinoic acid receptor alpha, FMS-like receptor tyrosine kinase 3 internal tandem duplication) are associated with PU.1 downregulation. To demonstrate directly a role of PU.1 in the blocked differentiation of leukemic blasts, we transduced cells from myeloid cell lines and primary blasts from AML patients with a lentivector encoding PU.1. In NB4 cells we obtained increases in PU.1 mRNA and protein, comparable to increases obtained with all-trans retinoic acid-stimulation. Transduced cells showed increased myelomonocytic surface antigen expression, decreased proliferation rates and increased apoptosis. Similar results were obtained in primary AML blasts from 12 patients. These phenotypic changes are characteristic of restored blast differentiation. PU.1 should therefore constitute an interesting target for therapeutic intervention in AML.

Abstract
PTB (polypyrimidine tract-binding protein) is a repressive regulator of alternative splicing. We have investigated the role of PTB in three model alternative splicing systems. In the alpha-actinin gene, PTB represses the SM (smooth muscle) exon by binding to key sites in the polypyrimidine tract. Repressive binding to these sites is assisted by co-operative binding to additional downstream sites. SM exon splicing can be activated by CELF proteins, which also bind co-operatively to interspersed sites and displace PTB from the pyrimidine tract. Exon 11 of PTB pre-mRNA is repressed by PTB in an autoregulatory feedback loop. Exon 11-skipped RNA gets degraded through nonsense-mediated decay. Less than 1% of steady-state PTB mRNA is represented by this isoform, but inhibition of nonsense-mediated decay by RNA interference against Upf1 shows that at least 20% of PTB RNA is consumed by this pathway. This represents a widespread but under-appreciated role of alternative splicing in the quantitative regulation of gene expression, an important addition to its role as a generator of protein isoform diversity. Repression of alpha-tropomyosin exon 3 is an exceptional example of PTB regulation, because repression only occurs at high levels in SM cells, despite the fact that PTB is widely expressed. In this case, a PTB-interacting cofactor, raver1, appears to play an important role. By the use of 'tethering' assays, we have identified discrete domains within both PTB and raver1 that mediate their repressive activities on this splicing event.

Abstract
The aim of this study was to evaluate the diagnostic usefulness of percutaneous liver biopsy and screening for hepatitis C virus antibodies with 1st and 2nd generation ELISA in asymptomatic blood donors with persistent (> 1 year) and moderate elevation (> 1.5 times the upper limit of normal) of serum alanine aminotransferase. The diagnosis was established from clinical, biological and ultrasound data before biopsies were obtained, then compared to the histological diagnosis. Thirty one of 56 blood donors who satisfied the preceding criteria accepted liver biopsy and were subsequently included in the study. An accurate diagnosis was proposed before biopsy in 20 cases. This was in agreement with the histological results in 19 cases but in 2 of these, unexpected lobular hepatitis was associated with the expected steatosis. Positive hepatitis C virus tests corresponded to chronic hepatitis in all cases (n = 5). No accurate diagnosis could be proposed in the 11 remaining cases owing to the lack of evidence of any etiology (n = 4) or because several potential etiologies were possible for the same subject (n = 7). Histological diagnoses were: isolated steatosis (n = 12), steatosis associated with lobular hepatitis (n = 7) or with chronic persistent hepatitis (n = 1), chronic active (n = 2) or chronic persistent hepatitis (n = 3), alcoholic hepatitis (n = 2), hemochromatosis (n = 1), and normal liver (n = 3). Liver biopsy is essential to the accurate etiological diagnosis of persistent and moderate elevation of aminotransferases despite hepatitis virus C tests which are associated with the correct diagnosis of chronic hepatitis in 16% of cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
175 Chronic HBs Ag carriers have been discovered in the blood donors of the Calvados blood transfusion center from 1971 to 1979. 72 of them (41%) gave their consent for a clinical and biological study at the end of 1979, after receiving a convocation letter. This work had two aims: - to study the epidemiological factors in this population. - to evaluate the clinical and biological consequences of persistent antigenemia. 1. Epidemiological Study. Most results agree with the literature (higher prevalence in male, age, stay in endemic countries) but some results disagree for several reasons: our donors are all volunteers, HBs Ag prevalence is low in our region, most of the patients are caucasian and with life conditions and habits which may explain some particularities in contagion. Furthermore, the relative number of blood donors found every year as chronic HBs Ag carriers, does not increase in our country. 2. The Clinical and Biological follow-up of 62 HBs Ag carriers (alcoholics excluded) was carried out for 4,3 years on average. No patients developed clinical and biological features of chronic liver disease. After a mean term follow-up, we conclude that the asymptomatic HBs Ag carriers state seems not to be of bad prognostic. Since long term complications cannot be excluded, the follow-up of these patients must be maintained.
