Neurodevelopmental outcomes of preterm infants born to preeclamptic mothers - A case-control study.

OBJECTIVE: Preeclampsia during pregnancy is associated with an increased risk for various neonatal morbidities. We aimed to investigate the association between prematurity due to maternal preeclampsia and developmental outcomes. STUDY DESIGN: This retrospective matched case-control study included 39 preterm infants (<32 weeks gestation) born to preeclamptic mothers between 2012 and 2016, compared with 39 infants born to mothers without preeclampsia. The two groups were matched for gestational age (±1 week), gender and plurality. Neurodevelopmental outcome was assessed using the Griffith's Mental Developmental Scales at 6, 12 and 24 months corrected age. RESULTS: The groups were comparable in terms of gestational age (30.2 weeks vs 29.8, P = 0.6), exposure to antenatal glucocorticosteroids and magnesium sulfate. The two groups differed significantly in birthweight so that cases had significantly lower birthweight, 1100 (IQR 844.5-1316.5) vs. 1370 (IQR 1174-1604.5) grams. 19/39 (48.7%) cases were small for gestational age compared with only 4/39 (10.3%) controls (P < 0.01). 16/39 of cases were born less than 1000 g, compared with only 5/39 controls (41% vs 12.8%, P < 0.01). Early complications were similar. Compared with controls, an overall trend for better neurodevelopmental performance on Griffith's score was found for cases, especially for early (6 months) non-motor performance. All severely disabled infants (Griffith's score < 55) at 24 months assessment were among controls. CONCLUSION: Although significantly smaller and smaller for gestational age, neurodevelopmental assessment by Griffiths' Mental Development Scales was similar for cases and controls with a trend towards better performance of cases at 6 months. Further studies are needed to determine whether the trend for better performance implies a developmental advantage.

Quantitative assessment of physical activity in pregnant women with sonographic short cervix and the risk for preterm delivery: A prospective pilot study.

OBJECTIVE: Bed rest or activity restriction is a common obstetrical practice, despite a paucity of data to support its efficacy. The aim of this study was to determine whether physical activity, as assessed by a smart band activity tracker, is associated with preterm birth in pregnant women at high risk for preterm delivery. METHODS: This was a pilot prospective cohort study including pregnant women at high risk for preterm delivery between 24 and 32 weeks-of-gestation. Physical activity level was assessed by smart band activity. Patients with sonographic short cervical length (≤ 20 mm) were asked to wear the smart band activity tracker continuously for at least one week, including one weekend. Both physicians and patients were blinded to the data stored in the smart band activity tracker. No specific recommendations were given to participants as to the level or intensity of physical activity. The primary outcome was the rate of preterm birth (< 37 weeks-of-gestation). Secondary outcomes included the rate of delivery before 34 weeks of gestation and neonatal outcome. Parametric and nonparametric statistics were used for analysis. RESULTS: Study population included 49 pregnant women: 37 women (75.7%) delivered preterm and 12 (24.5%) delivered at or after 37 weeks-of-gestation. The median steps per day was significantly lower in patients who delivered preterm (3576, IQR: 2478-4775 vs. 4554, IQR: 3632-6337, p = 0.02). Regression analysis revealed that the median number of steps per day was independently inversely associated with preterm birth, after adjustment for maternal age, body mass index, gestational age at recruitment, cervical length, cervical dilatation and plurality. CONCLUSION: This pilot study represents the first quantitative assessment of the association between physical activity and preterm birth. The results of this pilot study do not support the efficacy of decreased physical activity in the prevention of preterm birth in patients with sonographic short cervical length.

[Peripheral arthritis in polymyalgia rheumatica].

Polymyalgia rheumatica is characterized by aching and stiffness of the shoulder, the pelvic girdles and the neck. Peripheral joint involvement is less recognized by the medical community as a sign of the disease. In this article we present two patients whose disease was manifested by peripheral symptoms. The frequency, manifestations and the pathogenesis of the disorder are discussed and the importance of recognition of these symptoms and signs of the disease is stressed.
