Progression of cervical dilatation in normal human labor is unpredictable.

Introduction: The aim of this study was to analyze how the progression of cervical dilatation in active labor can be predicted by digital assessment in low-risk pregnant women, in spontaneous labor at term.

Material And Methods: This prospective observational study was performed on 328 women with singleton term gestations experiencing midwife-led labor according to local protocols, progressing to full dilatation and spontaneous delivery without any medical intervention. Mixed nonlinear models were adopted to (i) model individual cervical data into centile curves and (ii) calculate the time needed to gain 1 cm in cervical dilatation (TNG1cm ) modeled as a function of current dilatation.

The outcome of midwife-led labor in low-risk women within an obstetric referral unit.

Objective: To analyze maternal and neonatal outcomes of midwife-led labor in low-risk women at term.

Methods: Prospective observational cohort of 1788 singleton low-risk pregnancies in spontaneous term labor, managed according to a specific midwife-led labor protocol. Primary outcomes were mode of delivery, episiotomy, 3rd-4th degree lacerations, post-partum hemorrhage (PPH), need for blood transfusions, pH and Apgar score and NICU admissions.

Interleukin-13 and -4 expression in the central airways of smokers with chronic bronchitis.

The aim of this study was to determine whether the T-helper 2-type cytokines interleukin (IL)-13 and -4 are involved in mucus hypersecretion, the hallmark of chronic bronchitis (CB). Surgical specimens were examined from 33 subjects undergoing lung resection for localised peripheral malignant pulmonary lesions: 21 smokers with symptoms of CB, 10 asymptomatic smokers (AS) and two nonsmokers with normal lung function. The number of IL-4 and -13 positive (+) cells in the central airways was quantified.

Long-term follow-up of toluene diisocyanate-induced asthma.

Eighty-seven cases of occupational asthma induced by toluene diisocyanate (TDI) were diagnosed by an inhalation challenge with TDI and methacholine. After an average follow-up interval of 11 yrs, all subjects were re-examined. Of the 87 subjects examined, 13 (15%) had remained in the same job, 44 (50.

Inhibition of HIV-1 Tat activity correlates with down-regulation of bcl-2 and results in reduction of angiogenesis and oncogenicity.

The Tat protein of the human immunodeficiency virus type 1 promotes survival and growth and inhibits apoptosis of different cell types. These effects of Tat are attributed to the induction of bcl-2 gene expression. In this study we show that the blocking of both intracellular and extracellular Tat correlates with a decrease of bcl-2 transcripts, leading in vitro to a lower growth rate and attenuation of the transformed phenotype and in vivo to a reduced angiogenic and oncogenic activity of Tat-expressing cells.
