RESUMEN

Fetal growth restriction (FGR) is a common complication of pregnancy, associated with higher risk of perinatal mortality and adverse health and developmental outcomes for surviving infants. True FGR relates to a pathological restriction of fetal growth resulting from complex interactions between maternal, placental, fetal, and environmental factors. Early-onset FGR (onset <32 weeks' gestation) is often first suspected at routine mid-trimester sonographic assessment of fetal morphology, or identified as part of the placental syndrome, commonly maternal pre-eclampsia. Prenatal investigations may identify the cause of FGR. Timing of delivery is guided by serial sonographic surveillance of fetal growth and well-being and maternal condition, balancing the risk of stillbirth with the benefits of advancing gestation. This is particularly pertinent to severe early-onset FGR, a leading iatrogenic cause of very preterm birth. Prognosis is largely determined by the severity of FGR and its causes, gestation at birth, and birthweight. Pregnancy termination may be considered. Antenatal care and delivery in a tertiary center, provided by a multi-disciplinary team with expertise in managing high-risk pregnancies, are imperative to optimizing outcomes.

RESUMEN

BACKGROUND: Community violence is an understudied aspect of social context that may affect risk of preterm birth and small-for-gestational age (SGA). METHODS: We matched California mothers with live singleton births who were exposed to a homicide in their Census tract of residence in 2007-2011 to unexposed mothers within the same tract. We estimated risk differences with a weighted linear probability model, with weights corresponding to the matched data structure. We estimated the average treatment effect on the treated of homicide exposure on the risk of preterm birth and SGA during the preconception period and first and second trimester. RESULTS: We found a small increase in risk of SGA associated with homicide exposure in the first trimester (0.14% [95% confidence interval (CI) = -0.01%, 0.30%]), but not for exposure during the preconception period (-0.01% [95% CI = -0.17%, 0.15%]) or the second trimester (-0.06% [95% CI = -0.23%, 0.11%]). Risk of preterm birth was not affected by homicide exposure. When women were exposed to homicides during all three exposure windows, there was a larger increase in risk of SGA (1.09% [95% CI = 0.15%, 2.03%]) but not preterm birth (0.14% [95% CI = -0.74%, 1.01%]). Exposure to three or more homicides was also associated with greater risk of SGA (0.78% [95% CI = 0.15%, 1.40%]). Negative controls indicated that residual confounding by temporal patterning was unlikely. CONCLUSIONS: Homicide exposure during early pregnancy is associated with a small increased risk of SGA.

RESUMEN

BACKGROUND AND AIMS: Intrauterine growth restriction (IUGR) is a state of slower fetal growth usually followed by a catch-up growth. Postnatal catch-up growth in IUGR models increases the incidence of pulmonary arterial hypertension in adulthood. Here, we hypothesize that the adverse pulmonary vascular consequences of IUGR may be improved by slowing down postnatal growth velocity. Meanwhile, cognitive function was also studied. METHODS AND RESULTS: We established an IUGR rat model by restricting maternal food throughout gestation. After birth, pups were fed a regular or restricted diet during lactation by changing litter size. Thus, there were three experimental groups according to the dam/offspring diet: C/C (gold standard), IUGR with catch-up growth (R/C) and IUGR with delayed growth (R/D). In adulthood (14 weeks of age), we assessed pulmonary vascular development by hemodynamic measurement and immunohistochemistry. Our results showed that adult R/C offspring developed an elevated mean pulmonary arterial pressure (mPAP) and pulmonary arteriolar remodeling accompanied with decreased eNOS mRNA and protein expressions compared to C/C or R/D offspring. This suggested that delayed postnatal growth improved pulmonary circulation compared to postnatal catch-up growth. Conversely, adult R/D offspring performed poorly in cognition. Behavior test and electrophysiology results exhibited a reduced synaptic plasticity. Furthermore, decreased mRNA expression levels of the memory-related gene zif268 and transcription factor recruitment factor p300 in the hippocampus region were also observed in R/D group. CONCLUSION: These findings indicate that delayed postnatal growth results in cognitive impairment, but it reverses elevations in mPAP induced by postnatal catch-up growth following IUGR.

RESUMEN

BACKGROUND: The EVERREST Prospective Study is a multicentre observational cohort study of pregnancies affected by severe early-onset fetal growth restriction. The study recruits women with singleton pregnancies where the estimated fetal weight is less than the 3rd centile and below 600 g, between 20 + 0 and 26 + 6 weeks of pregnancy, in the absence of a known chromosomal, structural or infective cause. METHOD: The reported study was retrospective descriptive qualitative interview study of women who had participated in the EVERREST Prospective Study. The aim of this study was to explore the experiences and perceptions of pregnant women taking part in research during a pregnancy affected by severe early-onset fetal growth restriction. Audio-recorded semi-structured telephone interviews were conducted with a purposive sample of 12 women, at least 1 year after delivery of their baby. Two of these pregnancies had ended in stillbirth and one in neonatal death, reflecting the outcomes seen in the EVERREST Prospective Study. Participants gave informed consent, were 16 years or older and were interviewed in English. A topic guide was used to ensure a consistent approach. Questions focused on pregnancy experiences, involvement with the EVERREST study and potential involvement in future research. Recordings were transcribed verbatim for thematic analysis using NVivo10. RESULTS: Four broad themes were identified; 'before joining the EVERREST Prospective Study', 'participating in research', 'information and support' and 'looking back and looking forwards'. Each broad theme incorporated several subthemes. All participants recalled their reaction to being told their baby was smaller than expected. The way this news was given had a lasting impact. A range of benefits of participation in the EVERREST Prospective Study were described and the participants were positive about the way it was conducted. As a consequence, they were receptive to participating in future research. However, the findings suggest that research teams should be sensitive when approaching families at a difficult time or when they are already participating in other research. CONCLUSIONS: This study highlights the willingness of pregnant women to participate in research and identifies strategies for researchers to engage participants.

RESUMEN

Schizophrenia is a complex mental disorder with genetic and environmental components. Obstetric complications (OCs) are one of the most common environmental risk factors described. However, despite being different in timing and outcome, OCs are usually described as a homogeneous entity. In the present study, we evaluate the presence of different patterns of OCs evaluated with the Lewis-Murray Scale in chronic schizophrenia patients (n = 101) and their association with a crude marker of the intrauterine environment such as weight at birth.OCs related with abnormal fetal growth (p < 0.001) and OCs during gestation (p = 0.003) were associated with lower birth weight. However, difficulties in delivery, complications in pregnancy, and OCs all together (as a set) were not associated with weight at birth.Our results infer that OCs cannot be taken as a homogeneous group. Different patterns of OCs result in different birth weights, which is associated with specific metabolic, cognitive, and brain structure outcomes.

RESUMEN

BACKGROUND: Intrauterine growth restriction and premature birth represent 2 independent problems that may occur simultaneously and contribute to impaired neurodevelopment. OBJECTIVE: The objective of the study was to assess changes in the frontal lobe metabolic profiles of 1 year old intrauterine growth restriction infants born prematurely and adequate-for-gestational-age controls, both premature and term adequate for gestational age and their association with brain structural and biophysical parameters and neurodevelopmental outcome at 2 years. STUDY DESIGN: A total of 26 prematurely born intrauterine growth restriction infants (birthweight <10th centile for gestational age), 22 prematurely born but adequate for gestational age controls, and 26 term adequate-for-gestational-age infants underwent brain magnetic resonance imaging and magnetic resonance spectroscopy at 1 year of age during natural sleep, on a 3 Tesla scanner. All brain T1-weighted and diffusion-weighted images were acquired along with short echo time single-voxel proton spectra from the frontal lobe. Magnetic resonance imaging/magnetic resonance spectroscopy data were processed to derive structural, biophysical, and metabolic information, respectively. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales 3rd edition, assessing cognitive, language, motor, socioemotional, and adaptive behavior. RESULTS: Prematurely born intrauterine growth restriction infants had slightly smaller brain volumes and increased frontal lobe white matter mean diffusivity compared with both prematurely born but adequate for gestational age and term adequate for gestational age controls. Frontal lobe N-acetylaspartate levels were significantly lower in prematurely born intrauterine growth restriction than in prematurely born but adequate for gestational age infants but increased in prematurely born but adequate for gestational age compared with term adequate-for-gestational-age infants. The prematurely born intrauterine growth restriction group also showed slightly lower choline compounds, borderline decrements of estimated glutathione levels, and increased myoinositol to choline ratios, compared with prematurely born but adequate for gestational age controls. These specific metabolite changes were locally correlated to lower gray matter content and increased mean diffusivity and reduced white matter fraction and fractional anisotropy. Prematurely born intrauterine growth restriction infants also showed a tendency for poorer neurodevelopmental outcome at 2 years, associated with lower levels of frontal lobe N-acetylaspartate at 1 year within the preterm subset. CONCLUSIONS: Preterm intrauterine growth restriction infants showed altered brain metabolite profiles during a critical stage of brain maturation, which correlate with brain structural and biophysical parameters and neurodevelopmental outcome. Our results suggest altered neurodevelopmental trajectories in preterm intrauterine growth restriction and adequate-for-gestational-age infants, compared with term adequate-for-gestational-age infants, which require further characterization.

RESUMEN

The objective of this study was to evaluate the effect of anxiety-reducing techniques including music therapy, sophrology, and creative visualization in pregnant women with a fetus diagnosed as small for gestational age and improved fetal and neonatal weight. This was a quasi-experimental study with a nonrandomized clinical trial design. We compared 2 groups of pregnant women with a fetus diagnosed as small for gestational age with no abnormalities on Doppler studies. The control group (n = 93) received standard care, and the intervention group (n = 65), in addition to standard care, underwent a program of 6 sessions led by a midwife or nurse who taught anxiety-reduction techniques. The State-Trait Anxiety Inventory (STAI) including trait and state subscales were completed by both groups at the start of the study, and only the STAI-State subscale was completed again at the end of the study. Comparisons between the 2 groups regarding fetal weight and centile and maternal STAI scores were performed using the t test and the χ test. There were no significant differences in the STAI-Trait scores between the 2 groups. There were statistically significant differences in the intervention group's STAI-State score percentiles between the start and the end of the study, being lower at the end of the study (P < .001). There were significant differences between the 2 groups in fetal weight trajectory on the basis of fetal weight: the intervention group had a larger weight gain (P < .005). The program designed to reduce anxiety in pregnant women was effective at reducing anxiety in the women in the intervention group, leading to a favorable fetal weight trajectory in this group.

RESUMEN

Intrauterine growth restriction (IUGR) is a risk factor for memory impairment and emotional disturbance during growth and adulthood. However, this risk might be modulated by environmental factors during development. Here we examined whether exposing adolescent male and female rats with thromboxane A2-induced IUGR to social defeat stress (SDS) affected their working memory and anxiety-like behavior in adulthood. We also used BrdU staining to investigate hippocampal cellular proliferation and BrdU and NeuN double staining to investigate neural differentiation in female IUGR rats. In the absence of adolescent stress, IUGR female rats, but not male rats, scored significantly lower in the T-maze test of working memory and exhibited higher anxiety-like behavior in the elevated-plus maze test compared with controls. Adolescent exposure to SDS abolished these behavioral impairments in IUGR females. In the absence of adolescent stress, hippocampal cellular proliferation was significantly higher in IUGR females than in non-IUGR female controls and was not influenced by adolescent exposure to SDS. Hippocampal neural differentiation was equivalent in non-stressed control and IUGR females. Neural differentiation was significantly increased by adolescent exposure to SDS in controls but not in IUGR females. There was no significant difference in the serum corticosterone concentrations between non-stressed control and IUGR females; however, adolescent exposure to SDS significantly increased serum corticosterone concentration in control females but not in IUGR females. These results demonstrate that adolescent exposure to SDS improves behavioral impairment independent of hippocampal neurogenesis in adult rats with IUGR.

RESUMEN

OBJECTIVE: We assessed brain metabolite levels by magnetic resonance spectroscopy (MRS) in 1-year-old infants born small at term, as compared with infants born appropriate for gestational age (AGA), and their association with neurodevelopment at 2 years of age. STUDY DESIGN: A total of 40 infants born small (birthweight <10th centile for gestational age) and 30 AGA infants underwent brain MRS at age 1 year on a 3-T scanner. Small-born infants were subclassified as late intrauterine growth restriction or as small for gestational age, based on the presence or absence of prenatal Doppler and birthweight predictors of an adverse perinatal outcome, respectively. Single-voxel proton magnetic resonance spectroscopy ((1)H-MRS) data were acquired from the frontal lobe at short echo time. Neurodevelopment was evaluated at 2 years of age using the Bayley Scales of Infant and Toddler Development, Third Edition, assessing cognitive, language, motor, social-emotional, and adaptive behavior scales. RESULTS: As compared with AGA controls, infants born small showed significantly higher levels of glutamate and total N-acetylaspartate (NAAt) to creatine (Cr) ratio at age 1 year, and lower Bayley Scales of Infant and Toddler Development, Third Edition scores at 2 years. The subgroup with late intrauterine growth restriction further showed lower estimated glutathione levels at age 1 year. Significant correlations were observed for estimated glutathione levels with adaptive scores, and for myo-inositol with language scores. Significant associations were also noticed for NAA/Cr with cognitive scores, and for glutamate/Cr with motor scores. CONCLUSION: Infants born small show brain metabolite differences at 1 year of age, which are correlated with later neurodevelopment. These results support further research on MRS to develop imaging biomarkers of abnormal neurodevelopment.

RESUMEN

BACKGROUND: We hypothesized intrauterine growth restricted offspring (IUGR) demonstrate higher rates of aggression and higher dominance ranks than control (CTR) offspring with normal weight at term; if aggressive behavior is advantageous during resource scarcity, developmental programming may lead to an association between aggression and IUGR. METHODS: We studied 22 group-housed baboons (ages 3-5 years). CTR (male n = 8, female n = 5) mothers ate ad libitum. IUGR (male n = 4, female n = 5) mothers were fed 70% feed eaten by CTR mothers during pregnancy and lactation. RESULTS: IUGR showed higher rates of aggressive displays (P < 0.01) and friendly displays (P < 0.02). Dominance ranks and physical aggression rates did not differ between groups. CONCLUSIONS: High rates of IUGR aggressive display might reflect developmental programming of behavioral phenotypes enhancing fitness. Friendly displays may reflect reconciliation. Potential mechanisms include neurodevelopment and learning. Exploration of IUGR as a risk factor for behavioral patterns is important for developing diagnostic and therapeutic strategies.

RESUMEN

BACKGROUND: The aim of this study was to analyze whether late-onset fetal growth restriction (FGR) alters regulatory capability in infants, and whether this can be detected using both the neonatal behavior assessment scale (NBAS) and brainstem auditory-evoked potentials (BAEP). METHODS: The diagnosis of FGR was made on Doppler examination in the third trimester of pregnancy. NBAS and BAEP measurement were performed at 1 month of corrected postnatal age. RESULTS: The group with late-onset FGR was integrated with 17 infants and the control group consisted of 14 subjects. The NBAS range of state score, which reflects organization of behavioral state, was low in infants with late-onset FGR. No differences were found in BAEP between groups. No association between NBAS and BAEP was detected. CONCLUSION: Late-onset FGR has a deleterious effect on NBAS range of state, but possibly does not alter BAEP response. It is proposed that regulatory capabilities in the neonatal period play a primary role in subtle cognitive difficulties in infants with late-onset FGR in the long term.

RESUMEN

AIM: The main aim of the study was to estimate expression of Bcl-2 and Bax proteins in syncytiotrophoblast in placenta obtained from pregnancies complicated by hypertension and to compare results with group supplemented by antioxidants. MATERIAL AND METHOD: The study was performed in High Risk Department of Medical University Lodz. 3 groups of pregnant women were compared: I-pregnancy complicated by hypertension, II pregnancy complicated by hypertension treated by oral administration of antioxidants--vitamin C and vitamin E.III-rd group consisted of healthy women. After delivery incision from central part of placenta was taken on obtained slides due to immunohistochemical reactions the character intensity surface affected by reaction and expression of two proteins involved into process of apoptosis was measured- anti-apoptotic Bcl-2 and pro-apoptotic Bax. In every slide ten of random choosen fields were evaluated in 200x zoom using semi-quantative method. RESULTS: Highest value of Bcl-2 character was found in I-st group, the lowest in III-rd group- healthy women. The lowest intensity surface affected and expression of the reaction was found in II group- treated by antioxidants. The highest value of Bax reaction character and intensity was found in III group comparing to others. The lowest mean surface of syncytiotrophoblast affected by Bax reaction was found in II group. In III-rd group expression of reaction was higher than in both other groups. CONCLUSIONS: In the base of Bcl-2 reaction in syncytiotrophoblast no influence of antioxidants supplementation on apoptosis process that occurs by this path was found. Antioxidants supplementation decrease Bax activity in syncytiotrophoblast, that suggests restriction of apoptosis process despite of changes connected to hypertension.

RESUMEN

OBJECTIVE: The aim of this study is to evaluate corpus callosum (CC) development by Magnetic Resonance Imaging (MRI) in late-onset intrauterine growth restricted (IUGR) fetuses compared to appropriate for gestational age and its association with neurobehavioral outcome. METHOD: One hundred and seventeen late-onset IUGR and 73 control fetuses were imaged using a 3T MRI scanner at term, obtaining T2 half-Fourier acquisition single-shot turbo spin-echo anatomical slices. CC length, thickness, total area and the areas after a subdivision in 7 portions were assessed. Neonatal Behavioral Assessment Scale test was performed on IUGR newborns at 42 ± 1 weeks. RESULTS: IUGR fetuses showed significantly smaller CC (Total CC Area IUGR: 1.3996 ± 0.26 vs. AGA: 1.664 ± 0.31; p < 0.01) and smaller subdivision areas as compared with controls. The differences were slightly more pronounced in fetuses with very low birth weight and/or abnormal brain and/or abnormal uterine Doppler. CC measurements were significantly associated with neurobehavioral outcome in IUGR cases. CONCLUSIONS: CC development was significantly altered in late-onset IUGR fetuses and correlated with worse neurobehavioral performance. CC could be further explored as a potential imaging biomarker to predict abnormal neurodevelopment in pregnancies at risk.

RESUMEN

Embryonic diapauses mean that early embryos stop developing for some reasons in early pregnant stage. The embryo has dead in uterine cavity, but has not yet discharged. The early clinical manifestation in the areas of traditional Chinese medicine (TCM) can be classified as "pregnant vaginal bleeding", "fetal irritability" and other diseases. Embryonic diapause is a common and difficult gynecologic clinical disease. The prevalence rate which is increasing has become a major reproductive health problem. So the prevention research of embryonic diapauses is very significant. In this paper, through the induction and the summary of Chinese and Western medicine dynamic researches and control methods of embryonic diapauses, detailing a list of pathogenesis and treatment progress in embryonic diapauses. Besides, it can lay the foundation for further study and reducing embryonic diapauses incidence, which can promote reproductive health development.

RESUMEN

OBJECTIVE: To evaluate the 2-year neurodevelopmental outcome of full-term, small-for-gestational-age (SGA) newborns with normal placental function, according to current criteria based on umbilical artery Doppler findings. METHODS: A cohort of consecutive full-term, SGA newborns with normal prenatal umbilical artery Doppler was compared with a group of full-term, appropriate-for-gestational-age (AGA) infants sampled from our general neonatal population. Neurodevelopmental outcome was evaluated at 24 months' corrected age using the Bayley Scales of Infant and Toddler Development, 3(rd) Edition (Bayley-III), which evaluates cognitive, language, motor, social-emotional and adaptive competencies. The effect of the study group on each domain was adjusted with MANCOVA and logistic regression for gestational age at delivery, socioeconomic status, gender, tobacco smoking and breastfeeding. RESULTS: A total of 223 infants (112 SGA and 111 AGA) were included. The groups differed significantly with respect to socioeconomic status and gestational age at delivery. All studied neurodevelopmental domains were poorer in the SGA group, reaching significance for the cognitive (92.9 vs 100.2, adjusted P = 0.027), language (94.7 vs 101, adjusted P = 0.025), motor (94.2 vs 100, adjusted P = 0.027) and adaptive (89.2 vs 96.5, adjusted P = 0.012) scores. Likewise, the SGA group had a higher risk of low scores in language (odds ratio (OR) = 2.63; adjusted P = 0.045) and adaptive (OR = 2.72; adjusted P = 0.009) domains. CONCLUSIONS: Compared with normal-sized babies, full-term SGA infants, without placental insufficiency defined according to currently used criteria, have lower 2-year neurodevelopmental scores. These data challenge the concept that SGA fetuses with normal umbilical artery Doppler are 'constitutionally small' but otherwise completely normal.

RESUMEN

The clinical application of hypnosis has been effective in obstetrics. Intrauterine growth restriction and oligohydramnios are dreaded complications of pregnancy that may result in preterm deliveries causing increased perinatal morbidity and mortality. In this longitudinal prospective study, clinical hypnosis was used in addition to the conventional medical management in such pregnancies. The perinatal outcome was compared with the control group wherein hypnosis was not used. The hypnosis group had a significantly shorter preterm delivery rate (p = .004) and fewer incidence of low birth weight babies (p = .009). Significantly reduced operative intervention in terms of lower rate of cesarean section (p = .008) was also observed in the experimental group. Hence, the use of clinical hypnosis as a viable adjunct to medical management is suggested to help to prevent neonatal morbidity and fetal loss. A multicenter randomized, controlled clinical trial is encouraged in this area.

RESUMEN

Fetal growth restriction (FGR) increases the risk for impaired cognitive function later in life. However, the precise mechanisms remain elusive. Using dexamethasone-induced FGR and protein restriction-influenced FGR mouse models, we observe learning and memory deficits in adult FGR offspring. FGR induces decreased hippocampal neurogenesis from the early post-natal period to adulthood by reducing the proliferation of neural stem cells (NSCs). We further find a persistent decrease of Tet1 expression in hippocampal NSCs of FGR mice. Mechanistically, Tet1 downregulation results in hypermethylation of the Dll3 and Notch1 promoters and inhibition of Notch signaling, leading to reduced NSC proliferation. Overexpression of Tet1 activates Notch signaling, offsets the decline in neurogenesis, and enhances learning and memory abilities in FGR offspring. Our data indicate that a long-term decrease in Tet1/Notch signaling in hippocampal NSCs contributes to impaired neurogenesis following FGR and could serve as potential targets for the intervention of FGR-related cognitive disorders.

RESUMEN

Exposure to methamphetamine during brain development impairs cognition in humans and rodents. In mice, these impairments are more severe in females than males. Genetic factors, such as apolipoprotein E genotype, may modulate the cognitive effects of methamphetamine. Methamphetamine-induced alterations in the brain acetylcholine system may contribute to the cognitive effects of methamphetamine and may also be modulated by apolipoprotein E isoform. We assessed the long-term effects of methamphetamine exposure during brain development on cognitive function and muscarinic acetylcholine receptors in mice, and whether apolipoprotein E isoform modulates these effects. Mice expressing human apolipoprotein E3 or E4 were exposed to methamphetamine (5 mg/kg) or saline once a day from postnatal days 11-20 and behaviorally tested in adulthood. Muscarinic acetylcholine receptor binding was measured in the hippocampus and cortex. Methamphetamine exposure impaired novel location recognition in female, but not male, mice. Methamphetamine-exposed male and female mice showed impaired novel object recognition and increased number of muscarinic acetylcholine receptors in the hippocampus. The cognitive and cholinergic effects of methamphetamine were similar in apolipoprotein E3 and E4 mice. Thus, the cholinergic system, but not apolipoprotein E isoform, might play an important role in the long-term methamphetamine-induced cognitive deficits in adulthood.

RESUMEN

OBJECTIVE: To determine whether asthma-specific quality of life during pregnancy is related to asthma exacerbations and to perinatal outcomes. METHODS: This was a secondary analysis of data from a randomized controlled trial of inhaled beclomethasone versus theophylline in the treatment of moderate asthma during pregnancy. The Juniper Asthma Quality of Life Questionnaire (AQLQ) was administered to patients at enrollment. Exacerbations were defined as asthma symptoms requiring a hospitalization, unscheduled medical visit, or oral corticosteroid course. RESULTS: Quality of life assessments were provided by 310 of the 385 participants who completed the study. There was more than a 25% decrease in the odds of a subsequent asthma exacerbation for every 1-point increase in AQLQ score for the overall score (odds ratio [OR] 0.73, 95% confidence interval [CI] 0.55-0.96), emotion domain (OR 0.72, 95% CI 0.59-0.88), and symptoms domain (OR 0.73, 95% CI 0.57-0.94). These relationships were not significantly influenced by initial symptom frequency or forced expiratory volume in 1 s (FEV(1)). No significant relationships were demonstrated between enrollment AQLQ scores and preeclampsia, preterm birth, low birth weight, or small for gestational age. CONCLUSION: Asthma-specific quality of life in early pregnancy is related to subsequent asthma morbidity during pregnancy but not to perinatal outcomes.

RESUMEN

About 11% of pregnant women suffer from a major depression requiring treatment. If left untreated, there are specific risks such as preterm delivery or low birth weight. The initial difficulty lies in diagnosing the depression itself, since many depressive symptoms are falsely ascribed to the pregnancy. A further challenge is choosing the appropriate therapy. Treatment options are psychotherapy, antidepressants, electroconvulsive therapy (ECT), or the new option of light therapy. The choice of the most suitable treatment needs to be done together with the pregnant woman after careful clarification of the potential risks of each treatment option.
