“…The overall cesarean delivery rate for the entire study population was 21.7% (Table II), being higher in the High-Risk Aspirin study (36.9%) [7] than in the other three (18.2%) [4][5][6]. Among women who underwent cesarean delivery, non-reassuring fetal status was a more common indication among women diagnosed with oligohydramnios as was failed induction/failure to progress in labor (Table II).…”

“…However, the specific timing of the initial diagnosis of oligohydramnios relative to the time of admission was not recorded in any of the studies. In three of the four studies oligohydramnios was defined as either no amniotic fluid pocket 5 2 cm or, when using the 4-quadrant method, a sum of less than 5 cm [4,5,7]. In none of the studies were any specific ultrasonographic amniotic fluid measurements recorded.…”

“…These studies are The effects of asthma and treatment regimens on perinatal outcome [4] (Asthma Observational Study), Randomized clinical trial of the effect of metronidazole on pregnancy outcome in women infected with T. vaginalis or bacterial vaginosis [5] (BV/TV Study), Prevention of preeclampsia with low-dose aspirin in healthy, nulliparous pregnant women [6] (Low-Risk ASA Study) and Low-dose aspirin to prevent preeclampsia in women at high risk [7] (High-Risk ASA Study). These four studies are the only NICHD MFMU Network studies that routinely recorded the diagnosis of oligohydramnios and were thus chosen for this analysis.…”

Objective. We hypothesized that oligohydramnios would be diagnosed more frequently in the warm summer months when dehydration might be more common. Methods. The clinical diagnosis of oligohydramnios was extracted from the databases of four completed National Institute of Child Health and Human Development Maternal Fetal Medicine Units Network protocols. These data were stratified by quarter of delivery and compared using Fisher's Exact Test. Results. The clinical diagnosis of oligohydramnios was made more frequently in deliveries occurring in the summer months of June, July and August as compared with the remainder of the calendar year (7.2% vs 5.9%, p = 0.0178). Conclusions. In these studies the diagnosis of oligohydramnios is made more frequently in those pregnancies delivered during the summer months. Although not proven by this association, maternal dehydration may contribute to this finding.

“…During pregnancy, the one-third rule is classically mentioned, meaning that asthma improves in about one-third of women, worsens in another third, or remains stable in the others [168][169][170][171]. However, two prospective studies showed that in women with severe asthma, the condition is more likely to deteriorate than in mild asthma [172,173]. Menopause can coincide with the appearance of asthma, but whether it is the result of hormone replacement therapy is still controversial [174].…”
