In our previous work (https://journals.lww.com/greenjournal/Fulltext/2017/12000/Disparities_in_Chronic_Conditions_Among_Women.19.aspx), we identified higher rates of deliveries complicated by substance use among rural women. We knew that some of this difference would be accounted for by opioids.What we didn’t expect was that when we took a closer look, amphetamine use disorder accounted for a significant portion of this disparity as well.
The main findings of this study are that, between 2008-09 and 2014-15, amphetamine and opioid use among delivering women increased disproportionately across rural compared to urban counties in three of four census regions. By 2014-15, amphetamine use disorder was identified among approximately 1% of all deliveries in the rural western United States, which was higher than the incidence of opioid use in most regions.
Compared to opioid-related deliveries, amphetamine-related deliveries were associated with higher incidence of the majority of adverse gestational outcomes that we examined including pre-eclampsia, preterm delivery, and severe maternal morbidity and mortality.

Response: Many women who die within childbirth or soon thereafter experience rapid onset of morbidity/illness before succumbing. Thus, severe maternal morbidity (SMM) offers a detectable (or set of detectable) conditions that might be dealt with before they progress to a fatality. Even so, severe maternal morbidity alone can be non-fatal, but create disability for a new mother (e.g., a stroke), or prolong separation of mother and newborn.
So, we showed that, as the number of severe maternal morbidity indicators rises, so does the probability of maternal death. This relation was exponential in nature.

Response: Postnatal or postpartum depression is unfortunately common after giving birth; a figure often quoted is 15%, but some studies have found much higher numbers. Postnatal depression is associated with a range of poorer outcomes for mothers and their infants, and the financial costs of treating maternal mental ill health put health services under considerable strain. Studies have found that providing additional emotional support to at risk mothers, for instance via peer support programmes or regular phone calls with health visitors, can reduce the likelihood of them developing the condition. Therefore, it is really important that we understand the full range of risk factors that put women at greater risk of becoming depressed after giving birth.
There is increasing evidence for a link between inflammation and depression, with factors that trigger an inflammatory immune response also increasing the likelihood of depressive symptoms. The opens up the possibility of finding new risk factors for postnatal depression based on known associations with inflammation.

Response: The use of cannabis during pregnancy is a growing health concern, yet the long-term cognitive ramifications for developing offspring remain largely unknown. Human studies exploring the long-term effects of maternal cannabis use have been sparse for several reasons, including the length and cost of such studies, as well as the fact that experimentally assigning mothers to smoke cannabis during pregnancy is obviously ethically impractical. Animal models of maternal cannabis use have been advantageous in this respect, but they have been limited by the drugs used (synthetic cannabinoids vs. THC vs. cannabis plant) and the way that they are administered. In our study, we used a more translationally relevant animal model of maternal cannabis use that exposes pregnant rat dams to whole plant cannabis extracts using the intra-pulmonary route of administration that is most common to human users. Our preliminary data indicate that twice-daily exposure to a high-dose cannabis extract during pregnancy may produce deficits in cognitive flexibility in adult rat offspring. Importantly, these rats did not experience general learning deficits, as they performed comparably to non-exposed offspring when required to follow a cue in their environment that dictate reinforcer delivery. Instead, deficits were observed only when rats were required to disregard this previous cue-based strategy and adopt a new egocentric spatial strategy in order to continue receiving the sugar reinforcers.

Response: There is some evidence to suggest an increased likelihood of neurodevelopmental disorders in relation to hypertensive disorders in pregnancy, however consensus is lacking. Considering hypertensive disorders in pregnancy are among the most common prenatal complication, we decided to synthesise the published literature on this topic by conducting a comprehensive systematic review and meta-analysis.
Our main findings suggest that hypertensive disorders in pregnancy are associated with about 30% increase in the likelihood of autism spectrum disorders (ASD) and ADHD in the offspring, compared to offspring not exposed to hypertensive disorders in pregnancy.
