Objective: to study the factors associatedlost to follow-up in People Living with HIV on antiretroviral therapy (ART) at the Ambulatory Treatment Center (ATC). Methods: This is a retrospective casecontrol study of two years. It concerned all HIV-infected patients aged 15 and over who were started on ART for at least 4 months. Each case was matched with two controls by sex and age ± 5 years. Results: The proportionlost to follow-up was 21%.The median age lost to follow-up was 36 years (IQR: 30-42 years), sex ratio was 1.4 in favor of women. The median initial CD4 cell count was 151 cells/mm2 (IQR: 51-245) versus 207 (IQR: 67-482) for controls and the median lost to follow-up was 6 months (IQR: 4-9 months): 5-16) for controls. In multivariate analysis, the factors associated lost to follow-up were: unmarried (adjusted OR = 3.84, P = 0.0346); the initial CD4 <200 cells / mm3 (adjusted OR = 3.88, P = 0.0393) and the duration of ARV <= 6 months (adjusted OR = 6.59, P = 0.0047). The protective factors against lost to follow-up were: Body Mass Index of the last visited > = 18.5 kg / m2 (adjusted OR = 0.07, P = 0.0069); (OR adjusted = 0.06, P = 0.0197) and initiation to ART in the rainy season (adjusted OR = 0.21, P = 0.0220). Conclusion: These results can be supplemented by quantitative and qualitative studies. [ABSTRACT FROM AUTHOR]

This paper presents a new concept of aircraft tracking based on a LEO constellation of small satellites, each of them carrying receiving and transmitting devices in order to check the integrity of the ADS-B (Automatic Dependent Surveillance - Broadcast) positioning information and proceed with a non-cooperative independent localization of the aircraft, if a flight anomaly comes out. To do so, on side of the conventional ADS-B processing, authors propose to add a multilateration process and two active radar modes, able to perform a finer and reliable localization of the aircraft, as well as a first information on the nature of the flight anomaly. The paper deals with a preliminary system analysis, although underpinned by some illustrations of existing sensor technologies, already or nearly operational in space. The concept has been patented [1].

Abstract: The author is neither anthropologist nor invested in social activities. He has learned some reviews of anthropology and some social and philosophical books since seven years. He describe not a general review but an analysis of these lectures according to the composite tissues allotransplantations (CTA). The discussion concerns anthropology and symbols, philosophical and social aspects. There is a natural umbilicus between the anthropological science and the surgical art according to CTA.

Abstract: The first hand and face allografts opened a new era in medicine history: a time when allotransplantation and reconstructive surgery coupled their principles. Their success and their development made composite tissue allotransplantation (CTA) a clinical reality for our speciality. Although still recent and limited, experience from this new surgical practice will widen with feedback from the first clinical cases and with experience gained from more clinical cases, more anatomical areas, more type of allografts, more surgical techniques, more immunosuppressive regimens. Tongue, trachea, abdominal wall, uterus, penis allotransplantations have been performed, contemporarily. Whatever the future and the benefits for the selected patients might have been, reports from these — un- and misknown — cases contribute to a better knowledge of CTA, its therapeutic potential, its limits, its challenges.

Abstract: The author proves conclusions of that report on composite tissues allotransplantation (CTA). Cadaveric, functionnal and surgical anatomy has allowed the progress of reconstructive surgery since 30 years. It is an inventive, but always altruistic and emotional, reconstructive surgery which has allowed the progressiveness and expansion of CTA which is no more illusion but reality. The indications are and will remain exceptional. CTA''s expansion remain dependent on progress of immunosuppressive drugs, and the actual research is turning towards immunologic allowance, induced chimerism and genetic mosaicism. In French, CTA is also Ethics and it is the only one case in the world, according to the lawful activity of the Ethics'' advisory board. [Copyright &y& Elsevier]
