Lâhypertension pendant la grossesse chez les femmes sĂ©ropositives en Afrique subsaharienne : PrĂ©valence et les rĂ©sultats infantiles.
This analysis was performed to determine the prevalence of hypertension
and association of MAP (mean arterial pressure) with birth outcomes
among HIV-infected pregnant women not taking antiretrovirals.
HIV-infected pregnant women, enrolled into the HPTN024 trial in
Tanzania, Malawi and Zambia were followed up at 26-30, 36 weeks, and
delivery. The prevalence of hypertension was <1% at both 20-24 weeks
and 26-30 weeks and 1.7% by 36 weeks. A 5 mm Hg elevation in MAP
increased the risk of stillbirth at 20-24 weeks by 29% (p=0.001), 32%
(p=0.001) at 26-30 weeks and of low birth weight (LBW) at 36 weeks by
26% (p=0.001). MAP was not associated with stillbirth at 36 weeks, LBW
prior to 36 weeks, preterm birth, neonatal mortality or the risk of
maternal to child transmission (MTCT) of HIV (Afr J Reprod Health 2009;
13[4]:25-36).On a fait cette analyse pour déterminer la prévalence de
lâhypertension et lâassociation de la PAM (Pression
Artérielle Moyenne) avec les résultats de naissance chez les
femmes séropositives enceintes qui ne prennent pas des
médicaments antirétroviraux. Les femmes séropositives
enceintes inscrites pour lâessai PHTNO24 en Tanzanie, au Malawi
et en Zambie ont Ă©tĂ© suivies Ă 26 â 30, 36
semaines et Ă lâaccouchement. La prĂ©valence de
lâhypertension Ă©tait <1% Ă la fin de 20 â 24
semaines et Ă la fin de 26 â 30 semaines et 1,7% Ă la
fin de 36 semaines. Une hausse de 5mm Hg de la PAM a augmente le risque
de la mortinatalitĂ© Ă la fin de 20 â 24 semaines de 29%
(p = 0,001), 32% (p = 0,001) Ă la fin de 26 â 30 semaines et
de la faible poids de naissance (FPN) Ă la fin de 36 semaines de
26% (p = 0,001). La PAM nâĂ©tait pas liĂ©e Ă la
mortinatalité à la fin de 36 semaines, à la FPN avant 36
semaines, à la naissance avant-terme, à la mortalité
nĂ©onatale ou au risque de la transmission de la mĂšre Ă
lâenfant (TME) du VIH (Afr J Reprod Health 2009; 13[4]:25-36)
Progress in urban greenery mitigation science â assessment methodologies advanced technologies and impact on cities
Urban greenery is a natural solution to cool cities and provide comfort, clean air and significant social, health and economic benefits. This paper aims to present the latest progress on the field of greenery urban mitigation techniques including aspects related to the theoretical and experimental assessment of the greenery cooling potential, the impact on urban vegetation on energy, health and comfort and the acquired knowledge on the best integration of the various types of greenery in the urban frame. Also to present the recent knowledge on the impact of climate change on the cooling performance of urban vegetation and investigate and analyse possible technological solutions to face the impact of high ambient temperatures. © 2018 The Author(s)
