Youth partnership in suicide prevention research: moving beyond the safety discourse.

OBJECTIVE: In this communication article, we discuss coproduction in suicide prevention research, with an emphasis on involving young people. We critically reflect on the lessons we have learned by working alongside young people, and how these lessons may be useful to other research teams. SUMMARY: The meaningful involvement of young people in the design, implementation and translation of mental health research has received significant attention over the last decade. For most funding bodies, the involvement of patients and the public in the planning and delivery of research is advised and, in many cases, mandatory. When it comes to suicide prevention research, however, things are slightly different in practice. Involvement of young people in suicide prevention research has often been considered a controversial, unfeasible and even risky endeavour. In our experiences of working in this field, such concerns are expressed by funders, Higher Education Health and Safety committees and practitioners. By presenting an example from our research where the involvement of young people as experts by experience was integral, we highlight key lessons learnt that could maximise the potential of youth partnership in suicide prevention research. These lessons take on particular importance in mental health research against the background of long-entrenched power differences and the silencing of service user voices. Professional knowledge, obtained through education and vocational training, has historically taken priority over experiential knowledge obtained through lived experience, in psychiatric practice and research. Although this hierarchy has widely been challenged, any account of coproduction in mental health research is positioned against that background, and the remnants of those inequitable power relationships arguably take on greater resonance in suicide prevention research and require careful consideration to ensure meaningful involvement. CONCLUSION: We conclude that progress in suicide research cannot be fulfilled without the meaningful involvement of, and partnership with, young people with lived experience.

Society for Maternal-Fetal Medicine Special Statement: Prophylactic low-dose aspirin for preeclampsia prevention-quality metric and opportunities for quality improvement.

Prophylactic low-dose aspirin reduces the rates of preeclampsia, preterm birth, fetal growth restriction, and perinatal death in patients with risk factors for preeclampsia. Despite recommendations from the US Preventive Services Task Force, the American College of Obstetricians and Gynecologists, and the Society for Maternal-Fetal Medicine, low-dose aspirin use is reported in <50% of patients with high-risk factors and <25% of patients with >1 moderate-risk factor. These low use rates represent an important "quality gap" and demonstrate the need for quality improvement activities. In this article, we outline the specifications for a process metric to standardize the measurement of the rate of aspirin use. Furthermore, we outline an approach to conducting a quality improvement project to increase the use of aspirin by patients with risk factors for preeclampsia.

Society for Maternal-Fetal Medicine Special Statement: Postpartum visit checklists for normal pregnancy and complicated pregnancy.

Rising maternal morbidity and mortality rates, widening healthcare disparities, and increasing focus on cardiometabolic risk modification in at-risk patients have together catalyzed a shift in the postpartum care paradigm. What was once a single office visit in the 6 weeks after delivery is now being reimagined as a continuum of care that transitions patients from pregnancy to lifelong health optimization. However, this shift in postpartum care also comes with increased visit complexity and additional provider burden, particularly when patients have had significant pregnancy complications or have chronic diseases. To ensure that the comprehensive needs of both healthy and medically complex people are consistently met under this revised postpartum care paradigm, a postpartum visit checklist for uncomplicated postpartum patients and another checklist for those with major medical or obstetrical morbidities are presented. These checklists are designed to ensure that essential elements of physical and mental well-being are routinely considered, that adequate follow-up or specialty referrals are made, and that relevant future health risks are appropriately reviewed and discussed.

Society for Maternal-Fetal Medicine Special Statement: Quality metric for timely postpartum follow-up after severe hypertension.

Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality. Because postpartum exacerbation of severe hypertension is common, the American College of Obstetricians and Gynecologists recommends that patients with severe hypertension during the childbirth hospitalization be seen within 72 hours after discharge. In this statement, the Society for Maternal-Fetal Medicine proposes a uniform metric reflecting the rate of timely postpartum follow-up of patients with severe hypertension. The metric is designed to be measured using automated calculations based on billing codes derived from claims data. The metric can be used in quality improvement projects to increase the rate of timely follow-up in patients with severe hypertension during the childbirth hospitalization. Suggested steps for implementing such a project are outlined.

Planetary good governance after the Paris Agreement: The case for a global greenhouse gas tax.

The Paris Agreement and the subsequent IPCC Global Warming of 1.5 °C report signal a need for greater urgency in achieving carbon emissions reductions. In this paper we make a two stage argument for greater use of carbon taxes and for a global approach to this. First, we argue that current modelling tends to lead to a "facts in waiting" approach to technology, which takes insufficient account of uncertainty. Rather than look to the future, carbon taxes that facilitate social redesign are something we have control over now. Second, we argue that the "trade" in "cap and trade" has been ineffective and carbon trading has served mainly as a distraction. Carbon taxes provide a simpler more flexible and pervasive alternative. We conclude with brief discussion of global context.

Timing of Emergency Postpartum Hospital Visits in the Fourth Trimester.

OBJECTIVE: The concept of the "fourth trimester" emphasizes the importance of individualized postpartum follow-up. Women seek care for urgent issues during this critical time period. Our objective was to evaluate trends in presenting complaints and admissions in an emergency setting over the first 42 days following delivery. STUDY DESIGN: Postpartum hospital encounters within 42 days of delivery at our institution from 2015 to 2019 were studied. Demographic information, delivery route, and emergent hospital encounter details were obtained from the electronic medical record. The postpartum encounters were analyzed by week of presentation. Statistical analysis included Student's t-test and Mantel-Haenszel test with p <0.05 considered significant. RESULTS: Of the 8,589 deliveries, 491 (5.7%) were complicated by an emergent hospital presentation within 42 days of delivery resulting in 576 hospital encounters. 35.9% of these visits occurred in the first week and 75.5% occurred within the first 3 weeks. Women presenting to the hospital were more commonly African American, higher body mass index, and delivered via cesarean. The most common chief complaints were fever, headache, abdominal pain, vaginal bleeding, hypertension, and wound concerns with temporal trends noted. 72% of admissions occur within 14 days of delivery and drop dramatically thereafter (p = 0.001). The most common diagnoses were hypertension/preeclampsia with severe features, vaginal bleeding/delayed postpartum hemorrhage, and wound infection. CONCLUSION: We observed important trends in presenting complaints and admission diagnoses of emergency postpartum visits in the first 42 days. The majority of hospital visits and admissions occur within the first 2 weeks postpartum. Understanding maternal conditions and reasons for accessing care through an emergency setting allows for tailoring of routine postpartum follow-up. KEY POINTS: · Women presenting in the postpartum period most commonly seek care within 3 weeks of delivery.. · Postpartum presentations requiring admission most frequently occur within 2 weeks of delivery.. · The most common diagnoses on presentation were hypentension, vaginal bleeding, and wound infections..

A Gap in Care? Postpartum Women Presenting to the Emergency Room and Getting Readmitted.

OBJECTIVE: Emergent postpartum hospital encounters in the first 42 days after birth are estimated to complicate 5 to 12% of births. Approximately 2% of these visits result in admission. Data on emergent visits and admissions are critically needed to address the current maternal morbidity crisis. Our objective is to characterize trends in emergent postpartum hospital encounters and readmissions through chief complaints and admission diagnoses over a 4.5-year period. STUDY DESIGN: All postpartum hospital encounters within 42 days of delivery at our institution from 2015 to 2019 were included. We reviewed demographic information, antepartum, intrapartum, and postpartum care and postpartum hospital encounters. Trends in hospital presentation and admission over the study period were analyzed. Comparisons between women who were admitted to those managed outpatient were performed. Statistical analysis included Chi-square, student's t-test, and Mantel-Haenszel test for trend and ANOVA, as appropriate. A p-value <0.05 considered significant. RESULTS: Among 8,589 deliveries, 491 (5.7%) presented emergently to the hospital within 42 days of delivery, resulting in 576 hospital encounters. From 2015 to 2019, annual rates of presentation were stable, ranging from 5.0 to 6.4% (p = 0.09). Of the 576 hospital encounters, 224 (38.9%) resulted in an admission with increasing rates from 2.0% in 2015 to 3.4% in 2019 (p = 0.005). Primiparous women with higher body mass index, cesarean delivery, and blood loss ≥1, 000 mL during delivery were significantly more likely to be admitted to the hospital. Women with psychiatric illnesses increasingly utilized the emergency room in the postpartum period (6.7-17.2%, p = 0.03). The most common presenting complaints were fever, abdominal pain, headache, vaginal bleeding, wound concerns, and high blood pressure. Admitting diagnoses were predominantly hypertensive disorder (22.9%), wound complications (12.8%), endometritis (9.6%), headache (6.9%), and delayed postpartum hemorrhage (5.6%). CONCLUSION: The average proportion of women presenting for an emergent hospital encounter in the immediate 42-day postpartum period is 5.7%. Nearly 40% of emergent hospital encounters resulted in admission and the rate increased from to 2.0 to 3.4% over the study period. The most common reasons for presentation were fever, abdominal pain, headache, vaginal bleeding, wound concerns, and hypertension. Hypertension, wound complications, and endometritis accounted for the top three admission diagnoses.

Utility of follow-up standard sonography for fetal anomaly detection.

BACKGROUND: In 2014, the Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Imaging Workshop consensus recommended that sonograms be offered routinely to all pregnant women. In the absence of another indication, this examination is recommended at 18-22 weeks of gestation. Studies of anomaly detection often focus on pregnancies at risk for anomalies and on the yield of detailed sonography, topics less applicable to counseling low-risk pregnancies about the benefits and limitations of standard sonography. The clinical utility of follow-up sonogram in low-risk pregnancies for the purpose of fetal anomaly detection has not been established. OBJECTIVE: The objective of the study was to evaluate the utility of follow-up standard sonography for anomaly detection among low-risk pregnancies in a nonreferred population. STUDY DESIGN: We performed a retrospective cohort study of singleton pregnancies that underwent standard sonography at 18-21 6/7 weeks of gestation from October 2011 through March 2018 with subsequent delivery of a live-born infant at our hospital. Pregnancies with indications for detailed sonography in our system were excluded to evaluate fetal anomalies first identified with standard sonography. Anomalies were categorized according to the European Registration of Congenital Anomalies and Twins (EUROCAT) system, with confirmation based on neonatal evaluation. Among those with no anomaly detected initially, we evaluated the rate of subsequent detection according to number of follow-up sonograms, gestational age at sonography, organ system(s) affected, and anomaly severity. Statistical analyses were performed using χ2 and a Mantel-Haenszel test. RESULTS: Standard sonography was performed in 40,335 pregnancies at 18-21 6/7 weeks, and 11,770 (29%) had at least 1 follow-up sonogram, with a second follow-up sonogram in 3520 (9%). Major abnormalities were confirmed in 387 infants (1%), with 248 (64%) detected initially and 28 (7%) and 5 (1%) detected on the first and second follow-up sonograms. Detection of residual anomalies on follow-up sonograms was significantly lower than detection on the initial standard examination: 64% on initial examination, 45% for first follow-up, and 45% for second follow-up (P < .01). A larger number of follow-up examinations were required per anomalous fetus detected: 163 examinations per anomalous fetus detected initially, 420 per fetus detected at the first follow-up examination, and 705 per fetus detected at the second follow-up sonogram (P < .01). The number of follow-up examinations to detect each additional anomalous fetus was not affected by gestational age (P = .7). Survival to hospital discharge was significantly lower for fetuses with anomalies detected on initial (88%) than for fetuses with anomalies undetected until delivery (90 of 91, 99%; P < .002). CONCLUSION: In a low-risk, nonreferred cohort with fetal anomaly prevalence of 1%, follow-up sonography resulted in detection of 45% of fetal anomalies that had not been identified during the initial standard sonogram. Significantly more follow-up sonograms were required to detect each additional anomalous fetus.

Pharmacokinetics of amlodipine besylate at delivery and during lactation.

BACKGROUND: Amlodipine is rarely used in the treatment of pregnant hypertensive women due to limited pharmacokinetic data during pregnancy and the postpartum period. OBJECTIVE: To evaluate the pharmacokinetics of amlodipine besylate in the peri-partum period including quantities of placental passage, breast milk excretion and infant exposure. STUDY DESIGN: This was a prospective study of pregnant women who were prescribed 5 mg of amlodipine daily for treatment of chronic hypertension and delivered at term. Cord and maternal blood samples were collected at delivery. On postpartum day 2, six paired maternal plasma and breast milk samples were obtained at 4, 6, 8, 12, 15 and 24 h following amlodipine dosing. Infant plasma samples were collected 24-48 h after delivery. All samples were analyzed for amlodipine concentration. A one compartment, first-order model was used to calculate pharmacokinetic estimates for maternal plasma. RESULTS: Of the 16 patients enrolled in the study, 11 had cord blood and maternal serum collected at delivery, of which only 6 produced sufficient breast milk for sampling. Amlodipine was detected in infant cord blood plasma with a mean concentration of 0.49 ±â€¯0.29 ng/mL compared to mean maternal serum level of 1.27 ±â€¯0.84 ng/mL. Amlodipine concentrations in both in breast milk and infant plasma were undetectable at the lower limit of assay detection (<0.1 ng/mL). In the immediate postpartum period, the amlodipine elimination half-life was 13.7 ±â€¯4.9 h, the area under the curve was 53.4 ±â€¯19.8 ng*h/mL and the peak concentration was 2.0 ±â€¯1.0 ng/mL. CONCLUSIONS: Amlodipine does cross the placenta in measurable quantities, but is not detected in breast milk or infant plasma at 24-48 h of life indicating that it is likely safe to use during the peripartum period.

Perinatal outcomes associated with abnormal cardiac remodeling in women with treated chronic hypertension.

BACKGROUND: Adverse maternal outcomes associated with chronic hypertension include accelerated hypertension and resultant target organ damage. One example is long-standing hypertension leading to maternal cardiac dysfunction. Our group has previously identified that features of such injury manifest as cardiac remodeling with left ventricular hypertrophy. Moreover, these features of cardiac remodeling identified in women with chronic hypertension during pregnancy were associated with adverse perinatal outcomes. Recent definitions of maternal cardiac remodeling using echocardiography have been expanded to include measurements of wall thickness. We hypothesized that these new features characterizing cardiac remodeling in women with chronic hypertension may also be associated with adverse perinatal outcomes. OBJECTIVE: There were 3 aims in this study of women with treated chronic hypertension during pregnancy: to (1) apply the updated definitions of maternal cardiac remodeling; (2) elucidate whether these features of cardiac remodeling were associated with adverse perinatal outcomes; and (3) determine which, if any, of the newly defined cardiac remodeling strata were most damaging when compared to women with normal cardiac geometry. STUDY DESIGN: This was a retrospective study of women with treated chronic hypertension during pregnancy delivered from January 2009 through January 2016. Cardiac remodeling was categorized by left ventricular mass index and relative wall thickness into 4 groups determined using the 2015 American Society of Echocardiography guidelines: normal geometry, concentric remodeling, eccentric hypertrophy, and concentric hypertrophy. Perinatal outcomes were analyzed according to each category of cardiac remodeling compared with outcomes in women with normal geometry. RESULTS: A total of 314 women with treated chronic hypertension underwent echocardiography at a mean gestational age of 17.9 weeks. There were no differences between maternal age (P = .896), habitus (P = .36), or duration of chronic hypertension (P = .212) among the 4 groups. Abnormal cardiac remodeling was found in 51% and was significantly associated with increased rates of superimposed preeclampsia (P = .015), preterm birth (P < .001), and neonatal intensive care admission (P = .003). These outcomes reached the greatest significance when comparisons were made between eccentric hypertrophy and normal geometry. CONCLUSION: Using current American Society of Echocardiography guidelines, 51% of women with treated chronic hypertension during pregnancy have some degree of abnormal cardiac remodeling. Any suggestion of maternal cardiac remodeling, regardless of subtype, was associated with increased risks for superimposed preeclampsia and preterm birth with its resultant perinatal sequelae. Eccentric ventricular hypertrophy, previously thought to mimic exercise physiology, appears to be the most associated with adverse perinatal outcomes. Despite evidence of cardiac remodeling, ejection fraction was preserved.

Frequency and consequences of ventricular hypertrophy in pregnant women with treated chronic hypertension.

BACKGROUND: Ventricular hypertrophy is a known sequela of long-standing chronic hypertension with associated morbidity and mortality. OBJECTIVE: We sought to assess the frequency and importance of left ventricular hypertrophy in gravidas treated for chronic hypertension during pregnancy. STUDY DESIGN: This was a retrospective study of pregnant women with chronic hypertension who were delivered at our hospital from January 2009 through February 2015. All women who were given antihypertensive therapy underwent maternal echocardiography and were managed in a dedicated, high-risk prenatal clinic. Left ventricular hypertrophy was defined using the criteria of the American Society of Echocardiography as left ventricular mass indexed to maternal body surface area with a value of >95 g/m2. Maternal and infant outcomes were then analyzed according to the presence or absence of left ventricular hypertrophy. RESULTS: Of 253 women who underwent echocardiography, 48 (19%) met criteria for left ventricular hypertrophy. Women in this latter cohort were significantly more likely to be African American (P = .031), but there were no other demographic differences. More than 85% of the entire cohort had a body mass index >30 kg/m2 and a third of all women had class III obesity with a body mass index of >40 kg/m2. Importantly, duration of chronic hypertension (P = .248) and gestational age at time of echocardiography (P = .316) did not differ significantly between the groups. Left ventricular function was preserved in both groups as measured by left ventricular ejection fraction (P = .303). Those with ventricular hypertrophy were at greater risk to be delivered preterm (P = .001), to develop superimposed preeclampsia (P = .028), and to have an infant requiring intensive care (P = .023) when compared with women without ventricular hypertrophy. These findings persisted after adjustment for age, race, and parity. The gestational age at delivery according to measured left ventricular size was also examined and with increasing ventricular mass there was a significant association with the severity of preterm birth (P < .001). CONCLUSION: Left ventricular hypertrophy was identified in 1 in 5 women given antepartum treatment for chronic hypertension. Further analysis showed that these women were at significantly greater risk for superimposed preeclampsia and its attendant perinatal sequelae of preterm birth.

Impact of metabolic acidemia at birth on neonatal outcomes in infants born before 34 weeks' gestation.

PURPOSE: To examine prematurity-associated neonatal outcomes in early preterm infants with metabolic acidemia compared to those without such acidemia. METHODS: We performed a retrospective cohort analysis to assess the impact of metabolic acidemia on prematurity-associated complications in a large cohort of singleton live-born infants with complete umbilical cord gas analyses delivered between 24 0/7 and 33 6/7 weeks. Metabolic acidemia was defined as an umbilical artery pH less than 7.0 plus a base deficit of 12 mmol/L or greater. Outcomes were adjusted for gestational age using logistic regression. RESULTS: Between 1 January 1988 and 31 December 2014, 6970 singleton early preterm infants were delivered at our hospital, of which 126 (1.8%) had metabolic acidemia. Neonatal mortality as well as prematurity-associated morbidities were significantly increased in the presence of metabolic acidemia. Included were ventilator requirement (73% versus 36%, p < 0.001), grade 3/4 intraventricular hemorrhage (10% versus 4%, p < 0.001), periventricular leukomalacia (5% versus 2%, p = 0.036), and neonatal death (13% versus 4%, p < 0.001). These significant findings persisted after adjustment for gestational age. CONCLUSION: Metabolic acidemia significantly increases the risks related to prematurity in infants delivered prior to 34 weeks' gestation.

Association of Baseline Proteinuria and Adverse Outcomes in Pregnant Women With Treated Chronic Hypertension.

OBJECTIVE: To assess the importance of baseline proteinuria in women treated for chronic hypertension during pregnancy. METHODS: This retrospective cohort study included women with chronic hypertension who received antihypertensive therapy in the first half of pregnancy and completed urine protein quantification before 20 weeks of gestation. Maternal and neonatal outcomes were analyzed according to the presence or absence of baseline proteinuria, defined as 300 mg or greater per 24 hours identified before 20 weeks of gestation. Frequencies of superimposed preeclampsia, preterm birth, and small-for-gestational-age neonates were further evaluated according to stratified urine protein excretion levels from less than 50 mg to greater than 1,000 mg/24 hours. RESULTS: Between January 2002 and December 2014, a total of 447 women met inclusion criteria. Of these, 56 (13%) had baseline proteinuria. Women with baseline proteinuria were statistically significantly more likely to develop superimposed preeclampsia (79% compared with 49%), deliver preterm (18% compared with 6% 30 weeks of gestation or less, 34% compared with 17% 34 weeks of gestation or less, and 48% compared with 26% less than 37 weeks of gestation), and deliver an small-for-gestational-age neonate (41% compared with 22% less than the 10th percentile, 20% compared with 9% less than the third percentile) when compared with women who did not have proteinuria (all P<.05). Furthermore, the rates of superimposed preeclampsia and small for gestational age were significantly increased as 24-hour protein excretion levels increased across stratified levels (P for trend .002 and .015, respectively). When proteinuria levels less than 300 mg/d were analyzed separately, a significant association was observed for rates of superimposed preeclampsia and preterm birth. CONCLUSION: In pregnant women with treated chronic hypertension, baseline proteinuria was significantly associated with increased rates of preeclampsia, preterm birth, and growth restriction-even at proteinuria values previously considered to be within normal range (less than 300 mg/d).

Blood Pressure Profiles Across Pregnancy in Women with Chronic Hypertension.

Objective To examine blood pressure patterns across pregnancy in women with treated chronic hypertension according to the occurrence of severe preeclampsia, growth restriction, and preterm birth <34 weeks. Methods This retrospective descriptive case study included only pregnant women receiving antihypertensive therapy. Using a random effects model, mean arterial pressures were plotted across gestation for women with and without preeclampsia, fetal growth restriction, and preterm birth <34 weeks with differences analyzed for each curve. Results Between January 2002 and December 2014, 447 women met inclusion criteria. Of these women, 65% developed severe preeclampsia, 24% delivered an infant weighing <10th percentile, and 15% had a preterm birth <34 weeks. Women diagnosed with either preeclampsia (23.3 vs 26.4 weeks; mean difference, 3.1 weeks; 95% confidence interval [CI], 2.3-4.3), fetal growth restriction (23.5 vs 24.9 weeks; mean difference, 1.4 weeks; 95% CI, 0.2-2.6), or preterm birth (19.8 vs 24.9 weeks; mean difference, 5.1 weeks; 95% CI, 3.7-6.9) reached a blood pressure nadir at a significantly earlier gestational age than those who did not. Conclusion For pregnant women with treated chronic hypertension, blood pressure patterns differ significantly in those who develop severe preeclampsia, fetal growth restriction, and preterm birth <34 weeks.

Cardiac magnetic resonance imaging to assess the impact of maternal habitus on cardiac remodeling during pregnancy.

BACKGROUND: It is well known that the maternal cardiovascular system undergoes profound alterations throughout pregnancy. Interest in understanding these changes has led investigators to use evolving and increasingly sophisticated techniques to study these changes, most recently with 2-dimensional echocardiography. Despite its clinical utility, echocardiography has limitations, and cardiac magnetic resonance imaging (CMRI) has become increasingly used for evaluation of cardiac structure and function. OBJECTIVE: We used CMRI to evaluate cardiac remodeling according to maternal habitus throughout pregnancy and postpartum. STUDY DESIGN: This was a prospective, observational study of nulliparous women aged 18-30 years, without preexisting medical conditions, conducted from October 2012 through December 2014. Women were classified according to prepregnancy body mass index (BMI) as either normal (BMI 18.5-24.9 kg/m(2)) or overweight (BMI 25-35 kg/m(2)). All women underwent CMRI during 5 epochs throughout gestation: 12-16 weeks, 26-30 weeks, 32-36 weeks, at delivery, and 3 months' postpartum. Using left ventricular mass (LVM) as a marker of cardiac remodeling, the 2 cohorts were compared. RESULTS: There were 14 normal-weight (BMI 22.2 ± 1.3) and 9 overweight (BMI 29.1 ± 2.0) women who participated in the study. Beginning at 26-30 weeks and continuing to delivery, LVM of both normal-weight and overweight women was significantly increased compared with the respective first-trimester studies for each cohort (P < .001). LVM of both cohorts returned to their index values by 3 months' postpartum. The geometric ratio of LVM to left ventricular end-diastolic volume was calculated, and both normal-weight and overweight women demonstrated concentric remodeling throughout gestation, however this resolved by 12 weeks' postpartum. CONCLUSION: There is substantial cardiac remodeling during pregnancy with significant increases in LVM that are proportional to maternal size. Left ventricular geometric remodeling was concentric in both normal-weight and overweight women. All changes in cardiac remodeling resolved by 3 months' postpartum.
