Humans, Pregnancy, Female, Pilot Projects, Feasibility Studies, Pregnancy Outcome, Life Change Events, and Prenatal Care

Background: A healthy lifestyle plays a key role in the prevention of lifestyle-related diseases, including subfertility and pregnancy complications. Although the benefits of a healthy lifestyle are well-known, long-term adherence is limited. Moreover, memory for lifestyle-related information as well as medical information provided by the medical professional is often poor and insufficient. In order to innovate and improve health care for both the patients and health care professionals, we developed a prototype of a digital life course care platform (Smarter Health app), providing personalized lifestyle care trajectories integrated in medical care journeys.
Objective: This pilot study aimed to evaluate the feasibility, defined as the actual app use, and the acceptability, which included patient satisfaction and appreciation, of the Smarter Health app.
Methods: Between March 17, 2021, and September 30, 2021, pregnant women familiar with the Dutch language seeking tertiary preconception and pregnancy care were offered the app as part of standard medical care at the outpatient clinic Healthy Pregnancy of the Department of Obstetrics and Gynecology of the Erasmus University Medical Center. Three months after activation of the app, patients received a digital questionnaire consisting of aspects of feasibility and acceptability.
Results: During this pilot study, 440 patients visited the outpatient clinic Healthy Pregnancy. Of the 440 patients, 293 (66.6%) activated the app. Of the 293 patients who activated the app, 125 (42.7%) filled out the questionnaire. Of these 125 patients, 48 (38.4%) used the app. Most app users used it occasionally and logged in 8 times during their medical care trajectory. Overall, app users were satisfied with the app (median 5-point Likert scale=2.4, IQR 2.0-3.3).
Conclusions: Our findings showed that the Smarter Health app, which integrates lifestyle care in medical care, is a feasible health care innovation, and that patients were satisfied with the app. Follow-up and evaluation of pregnancy outcomes should be performed to further substantiate wider clinical implementation.

Objectives: In this study we describe the development and validation of a liquid chromatography mass spectrometry method (LC-MS/MS) to quantify five tryptophan (TRP) metabolites within the kynurenine- and serotonin pathway and apply the method to serum samples of women in the first trimester of pregnancy. A secondary aim was to investigate the correlation between body mass index (BMI) and the five analytes.
Methods: A LC-MS/MS was developed for the analysis of TRP, kynurenine (KYN), 5-hydroxytryptophan (5-HTP), hydroxytryptamine (5-HT), and 5-hydroxyindole acetic acid (5-HIAA). Serum samples (n=374) were analyzed of pregnant women (median gestational age: 8 ± 2 weeks) participating in a subcohort of the Rotterdam Periconceptional Cohort (Predict study).
Results: The LC-MS/MS method provided satisfactory separation of the five analytes (7 min run). For all analytes R 2 was >0.995. Within- and between-run accuracies were 72-97% and 79-104%, and the precisions were all <15% except for the between-run precisions of the low QC-samples of 5-HTP and 5-HT (both 16%). Analyte concentrations were determined in serum samples of pregnant women (median (IQR)); TRP (µmol/L): 57.5 (13.4), KYN (µmol/L): 1.4 (0.4), 5-HTP (nmol/L): 4.1 (1.2), 5-HT (nmol/L): 615 (323.1), and 5-HIAA (nmol/L): 39.9 (17.0). BMI was negatively correlated with TRP, 5-HTP, and 5-HIAA (TRP: r=-0.18, p<0.001; 5-HTP: r=-0.13, p=0.02; natural log of 5-HIAA: r=-0.11, p=0.04), and positively with KYN (r=0.11, p=0.04).
Conclusions: The LC-MS/MS method is able to accurately quantify kynurenine- and serotonin pathway metabolites in pregnant women, providing an opportunity to investigate the role of the TRP metabolism in the (patho)physiology of pregnancy.

Pregnancy, Female, Humans, Life Style, Pregnancy Outcome, Patient Care, Preconception Care, and Life Change Events

It is well known that a healthy lifestyle plays a key role in maintaining reproductive and general health, and preventing lifestyle-related diseases throughout the entire life course. Lifelong health is shaped during the preconception period and the first 1000 days of life. The importance of a healthy lifestyle during these periods can be emphasized by introducing the concept of the early life course, which covers from 100 days before conception until 1000 days thereafter. Although awareness of the benefits of a healthy lifestyle has grown, adherence is disappointing and the implementation of lifestyle interventions in medical care is scarce. Hence, we are convinced that now is the right time to turn the tide. The focus should shift from cure to prevention and promotion of health. The new concept of lifestyle care includes lifestyle interventions that support the adoption of a healthy lifestyle to optimize health and prevent lifestyle-related diseases, including subfertility and adverse pregnancy outcomes. In this paper, we advocate for the implementation of lifestyle care in medical care, define the early life course, elaborate on lifestyle care as part of lifestyle medicine, and provide examples towards the successful implementation of blended lifestyle care, which can be more widely implemented and transform medical care.

Research Question: What is the association between the degree of a state of maternal vulnerability, determined by suboptimal periconceptional social, lifestyle and medical exposures and embryonic growth?
Design: In total, 555 pregnancies, comprising 324 naturally conceived pregnancies and 231 pregnancies conceived after IVF and intracytoplasmic sperm injection (ICSI) were included from the Rotterdam Periconceptional Cohort (Predict Study) between November 2010 and August 2018. Data on periconceptional social, lifestyle and medical exposures, i.e. vulnerability markers, were collected through self-administered questionnaires. To estimate embryonic growth, crown-rump length (CRL) and embryonic volume measurements were taken at 7, 9 and 11 weeks of gestation using three-dimensional ultrasound scans and virtual reality techniques.
Results: Exposure to two or more vulnerability markers was negatively associated with embryonic growth in naturally conceived pregnancies. The CRL and embryonic volume trajectories of embryos of women exposed to two vulnerability markers were reduced compared with those of women exposed to zero or one vulnerability marker (√CRL: β = -0.29 mm, 95% CI -0.56 to -0.02; 3√EV: β = -0.14 cm 3 , 95% CI -0.27 to -0.01). These associations were not found in pregnancies conceived after IVF or ICSI.
Conclusions: This study showed that a higher degree of the periconceptional state of maternal vulnerability is associated with reduced embryonic growth (CRL and embryonic volume) in naturally conceived pregnancies.

Poor lifestyle behaviors impact (pre)pregnant women by affecting pregnancy outcomes and offspring health. This systematic review provides an overview of psychological therapies to support lifestyle behavior changes among (pre)pregnant women. Scientific databases were searched from their inception to 20 December 2020 for studies investigating the effects of psychological therapies on improvements in lifestyle behaviors. Studies were eligible if they included (pre)pregnant women, examined the effects of a psychological therapy on at least one lifestyle behavior and used a control group receiving usual pregnancy care or a non-psychological intervention. Lifestyle behaviors of interest were dietary intake, physical activity, smoking, alcohol consumption, drug use, body weight loss and body weight gain during pregnancy. Pregnancy complications were included as outcome measures. Motivational interviewing (MI) (n = 21), cognitive behavioral therapy (CBT) (n = 8), incentive-based contingency management (IBCM) (n = 9), mindfulness (n = 1) and hypnosis (n = 1) were investigated as lifestyle behavior interventions. The findings revealed that MI was effective in reducing (self-reported) smoking and alcohol consumption and restricting gestational weight gain (GWG). CBT was only studied as an intervention to restrict GWG and the results predominantly confirmed its effectiveness. IBCM showed the strongest effect on reducing smoking and substance use. The studies using hypnosis or mindfulness to reduce smoking or restrict GWG, respectively, showed no associations. The use of psychological therapies to improve lifestyle behaviors among (pre)pregnant women is new and the scientific proof is promising. Before wide implementation is legitimated, more evidence is needed on the consequences of lifestyle change for pregnancy outcomes.
