“…The placental weight (on average 525 g) was also lower than normative values for full‐term babies (between 668 and 680 g) (Almog et al, ). Studies have demonstrated that there is a higher incidence of fetal heart rate variability and of birth asphyxia with shorter or longer cords (Balkawade & Shinde, ), and that fetal/placental weight ratio may be associated with adverse perinatal outcomes (Matsuda et al, ). However, the sample is very small to make a valid conclusion.…”

A pediatric registry for arthrogryposis multiplex congenita (AMC) proposes to advance research by providing the platform to inform the distribution, etiology, and natural history of AMC. The registry was piloted on 40 families of children (mean = 8.25 years, 48% males) presenting with AMC across two hospitals in North America. Data on the child's demographic and newborn variables, mothers' and fathers' demographic variables, lifestyle habits, and medical history were collected using a telephone interview with the primary caregiver and review of medical charts.Mean gestational age was 38 weeks, 97% of children presented with lower extremity deformities, and 74% of neonatal interventions targeted the lower extremity. Newborns spent an average of 14 days in the hospital (range 2-56 days) mostly for diagnostic workup and feeding difficulties. Half (49%) of the sample had internal organ involvement. Genetic testing was done on 48% of the children, including chromosome studies, single gene, whole-exome/genome sequencing, and/or microarray studies. Genetic findings were inconclusive in most. Two-thirds of mothers (67%) reported inconsistently feeling fetal movements. This pilot study contributed to the refinement of participant selection, identification of data source, expansion of data sets, and areas for future exploration prior to the implementation of a multisite AMC pediatric registry.

“…Oversized placentas are also often observed at an early gestational age . In a previous study, we defined inappropriately heavy placenta as cases with a high PW Z score (over +1.28 SD) and low F/P Z score (under −1.28 SD) (Category I) and found that the proportion in the LFD‐VD group was 0.5% . However, in cases of high‐risk pregnancy, such as HDP, especially during early gestation, CS seems to be performed due to maternal or fetal indications, such as intractable hypertensive crisis, threatened damage to vital organs, fetal growth restriction and non‐reassuring fetal status.…”

“…As a result, the nine groups shown in Figure were made, and we labeled them from top‐left (Category A: inappropriately light placenta, relatively heavy infant) to bottom‐right (Category I: inappropriately heavy placenta, relatively small infant). Category E was located in the center of the nine category classifications (9‐CC) and considered a control for the remaining eight groups, as described previously …”

“…The Y ‐axis represents the F/P Z score focusing on scores of −1.28 SD and 1.28 SD. The characteristics of nine categories made by PW and F/P Z scores are showed which considered the relationships between BW and PW, as previously described . BW, body weight; F/P fetal/placental weight ratio; PW, placental weight; SD, standard deviation.…”

“…There have been no reports using both Z scores together for the evaluation of perinatal outcomes. Therefore, we speculated that the evaluation of LFD infants with Z scores for both PW and F/P would be more reliable than the indices presented in previous paper …”

Aim:The difference of placental weight (PW) and fetal/placental weight ratio (F/P) Z scores by mode of delivery is unclear. To investigate such differences and the actual conditions underlying the imbalance between fetal and placental growth. Methods: The data from Japanese database 2013 were assessed. Light-for-dates (LFD, n = 12 884), appropriate-for-dates (n = 114 464) and heavy-for-dates (n = 13 164) from 140 512 placentas/infants of mothers delivered a singleton infant. Using Z scores of PW and F/P based on the standard curves of a sex-, parity-and gestational-age-specific PW and F/P, the rate of inappropriately heavy placenta according to the mode of delivery (vaginal [VD] vs cesarean [CS]) was investigated. Results: (i) The PW and F/P were heavier and bigger in VD than in CS, in each subgroup. In the LFD groups, the PW Z score in VD was higher than that in CS, whereas the F/P Z score was lower than in VD than that in CS. (ii) Data of single regression analyses between the PW Z score and F/P Z score in VD groups were different from those in CS, especially in LFD infants. (iii) In the LFD subgroups, the rates of inappropriately heavy placenta in VD (n = 7781) and CS (n = 5103) were 0.54% and 0.86%, respectively. Conclusion: Difference in the mode of delivery influenced the PW and F/P, and the rate of inappropriately heavy placenta is associated with mode of delivery among LFD infants. This methodology might give us a clue to search a useful way for identifying the high-risk groups requiring postnatal counseling.

Healthy lifestyles and noncommunicable diseases: Nutrition, the life‐course, and health promotion

Cardiovascular disease, cancer, diabetes, and chronic respiratory diseases, targeted by Sustainable Development Goal 3.4, afflict millions of people and account for the highest global morbidity and mortality. Obesity is associated with noncommunicable diseases. Globally, diets have become sweeter, saltier with higher fat content, whereas physical activity has declined; which triggers the onset of obesity and noncommunicable diseases. Healthy nutrition and regular exercise are the foundations for healthy living and important for preventing noncommunicable diseases, in alignment with health promotion. The preconception, gestational, and lactational periods present windows for improving and optimizing progeny growth and development for better health outcomes. Malnutrition is a major risk factor for noncommunicable diseases; therefore ingesting healthy nutritious food, over the life‐course, is critical for countering these global epidemics that have a more profound adverse impact on people from low‐ and middle‐income countries. To combat obesity and noncommunicable diseases, people's ownership of their health, government action, and private sector responsibility should be aligned and supported by global initiatives and enabled through partnerships and collaborations. Many noncommunicable diseases are avertable through health promotion strategies mainly directed at the maternal and child health lifecycle, by focusing on women of reproductive age (prior to and during pregnancy, and during lactation) and during infancy and childhood, adolescence, adulthood, and ageing. Healthy lifestyles support health promotion and disease prevention, which is cost‐effective for noncommunicable diseases. The global high burden of obesity and noncommunicable diseases remains a complex and prevalent challenge; therefore, the adoption of healthy lifestyles is critical to slow down their onset and exacerbation.
