Predictors of inadequate gestational weight gain according to iom recommendations and intergrowth-21st standards: the araraquara cohort study.

BACKGROUND: Gestational weight gain (GWG) is a critical factor for maternal and fetal health. OBJECTIVE: To identify maternal predictors of inadequate GWG according to the 2009 Institute of Medicine (IOM) recommendations and Intergrowth-21st standards. METHODS: A prospective epidemiological cohort study conducted from 2017 to 2023 in southeastern Brazil assessed 1,557 women at three different stages of pregnancy (≤ 18, 20-26, and 30-36 weeks of gestation) and at delivery. Sociodemographic, obstetric, lifestyle, nutritional, and maternal morbidity characteristics were collected, along with biochemical parameters. RESULTS: Among the participants, 38.7% had GWG above IOM recommendations, while 67.5% had GWG above the Intergrowth-21st standards. Multinomial logistic regression analysis showed that women with pre-pregnancy obesity and women with the highest body fat percentage had, respectively, a 95% (OR = 1.95; 95% CI: 1.08-3.51) and 1% (OR = 1.01; 95% CI: 1.01-1.05) higher chance of GWG above IOM recommendations. Pregnant women in the lowest tertile of height, smokers, number of previous pregnancies, and women living in crowded homes had, respectively, a 57% (OR = 0.57; 95% CI: 0.41-0.80), 36% (OR = 0.64; 95% CI: 0.37-0.86), 35% (OR = 0.65; 95% CI: 0.43-0.97), and 14% (OR = 0.86; 95% CI: 0.59-0.86) lower chance of GWG above IOM recommendations. Women with diabetes were 2.53 times more likely (OR = 2.53; 95% CI: 1.32-4.83) to have GWG below IOM recommendations. Using the Intergrowth-21st standards, women with the highest body fat percentage had a 12% (OR = 1.12; 95% CI: 1.02-1.24) higher chance of GWG above the 90th percentile. Pregnant women in the lowest tertile of height were 2.82 times more likely (OR = 2.82; 95% CI: 1.08-8.13) and women with the lowest hemoglobin concentrations had a 41% lower chance (OR = 0.59; 95% CI: 0.39-0.88) of having GWG below the 10th percentile. While both guidelines identified body fat percentage and pre-pregnancy obesity as significant predictors of excessive GWG, the Intergrowth-21st standards captured a higher percentage of women exceeding GWG limits. CONCLUSION: The findings underscore the importance of comparing two instruments for assessing the adequacy of GWG. The IOM and Intergrowth-21st standards provide complementary insights, which can help implement targeted interventions for specific groups of women based on their nutritional and socioeconomic status, lifestyle, and obstetric factors to prevent pregnancy-related complications.

Predictors of low birthweight and comparisons of newborn birthweights among different groups of maternal factors at Rev. John Chilembwe Hospital in Phalombe district, Malawi: A retrospective record review.

BACKGROUND: Birthweight has an impact on newborn's future health outcomes. Maternal factors, including age, delivery mode, HIV status, gestational age, parity and obstetric complications (preeclampsia or eclampsia [PE], antepartum hemorrhage [APH] and sepsis), however, have been shown as risk factors of low birthweight (LBW) elsewhere. For data-guided interventions, we aimed to identify predictors of LBW and compare newborn birthweights between different groups of maternal factors at Rev. John Chilembwe Hospital in Phalombe district, Malawi. METHODS: Using a retrospective record review study design, we extracted data from maternity registers of 1244 women and their newborns from October, 2022 to March, 2023. Data were skewed. Median test was used to compare median birthweights. Chi-square or Fisher's exact tests were used to compare proportions of LBW among different groups of maternal factors. Multivariable logistic regression with stepwise, forward likelihood method was performed to identify predictors of LBW. RESULTS: Median birthweight was 2900.00g (interquartile range [IQR]: 2600.00g to 3200.00g). Prevalence of LBW was 16.7% (n = 208). Proportions of LBW infants were higher in women with PE, APH, including women with sepsis than controls (10 [47.6%] of 21 vs 7 [58.3%] of 12 vs 191 [15.8%] of 1211, p < .001). Lower in term and postterm than preterm (46 [5.5%] of 835 vs 2 [3.7%] of 54 vs 160 [45.1%] of 355, p < .001). The odds of LBW infants were higher in preterm than term (AOR = 13.76, 95%CI: 9.54 to 19.84, p < .001), women with PE (AOR = 3.88, 95%CI: 1.35 to 11.18, p = .012), APH, including women with sepsis (AOR = 6.25, 95%CI: 1.50 to 26.11, p = .012) than controls. CONCLUSION: Prevalence of LBW was high. Its predictors were prematurity, PE, APH and sepsis. Interventions aimed to prevent these risk factors should be prioritized to improve birthweight outcomes.

Prevalence of macrosomic newborn and maternal and neonatal complications in a high-risk maternity.

Objective: Evaluate the prevalence of macrosomic newborns (birth weight above 4000 grams) in a high-risk maternity from 2014 to 2019, as well as the maternal characteristics involved, risk factors, mode of delivery and associated outcomes, comparing newborns weighing 4000-4500 grams and those weighing above 4500 grams. Methods: This is an observational study, case-control type, carried out by searching for data in hospital's own system and clinical records. The criteria for inclusion in the study were all patients monitored at the service who had newborns with birth weight equal than or greater than 4000 grams in the period from January 2014 to December 2019, being subsequently divided into two subgroups (newborns with 4000 to 4500 grams and newborns above 4500 grams). After being collected, the variables were transcribed into a database, arranged in frequency tables. For treatment and statistical analysis of the data, Excel and R software were used. This tool was used to create graphs and tables that helped in the interpretation of the results. The statistical analysis of the variables collected included both simple descriptive analyzes as well as inferential statistics, with univariate, bivariate and multivariate analysis. Results: From 2014 to 2019, 3.3% of deliveries were macrosomic newborns. The average gestational age in the birth was 39.4 weeks. The most common mode of delivery (65%) was cesarean section. Diabetes mellitus was present in 30% of the deliveries studied and glycemic control was absent in most patients. Among the vaginal deliveries, only 6% were instrumented and there was shoulder dystocia in 21% of the cases. The majority (62%) of newborns had some complication, with jaundice (35%) being the most common. Conclusion: Birth weight above 4000 grams had a statistically significant impact on the occurrence of neonatal complications, such as hypoglycemia, respiratory distress and 5th minute APGAR less than 7, especially if birth weight was above 4500 grams. Gestational age was also shown to be statistically significant associated with neonatal complications, the lower, the greater the risk. Thus, macrosomia is strongly linked to complications, especially neonatal complications.

Validation study of obstetric hospitalization data held on the Brazilian National Health System Hospital Information System for maternal morbidity surveillance: Brazil, 2021-2022.

OBJECTIVE: To validate the Brazilian National Health System Hospital Information System (SIH/SUS) for maternal morbidity surveillance. METHODS: This was a cross-sectional study conducted in 2021/2022, taking as its reference a national study on maternal morbidity (MMG) conducted in 50 public and 28 private hospitals; we compared SIH/SUS and MMG data for hospitalization frequency, reason and type of discharge and calculated sensitivity, specificity, positive and negative likelihood ratios for seven diagnoses and four procedures. RESULTS: Hospitalizations identified on SIH/SUS (32,212) corresponded to 95.1% of hospitalizations assessed by MMG (33,867), with lower recording on SIH/SUS (85.5%) for private hospitals [10,036 (SIH/SUS)]; 11,742 (MMG)]; compared to MMG, SIH/SUS had a lower proportion of hospitalizations due to "complications during pregnancy" (9.7% versus 16.5%) as well as under-recording of all diagnoses and procedures assessed, except "ectopic pregnancy". CONCLUSION: Better recording of diagnoses and procedures on SIH/SUS is essential for its use in maternal morbidity surveillance.

Risk of Adverse Neonatal Events in Pregnancies Complicated by Severe Maternal Morbidity.

OBJECTIVE: To investigate the risk of adverse neonatal events after a pregnancy complicated by severe maternal morbidity. STUDY DESIGN: We analyzed a population-based cohort of deliveries in Quebec, Canada, between 2006 and 2021. The main exposure measure was severe maternal morbidity, comprising life-threatening conditions such as severe hemorrhage, cardiac complications, and eclampsia. The outcome included adverse neonatal events such as very preterm birth (gestational age <32 weeks), bronchopulmonary dysplasia, hypoxic ischemic encephalopathy, and neonatal death. Using log-binomial regression models, we estimated adjusted relative risks (RRs) and 95% confidence intervals (CIs) for the association between severe maternal morbidity and adverse neonatal events. RESULTS: Among 1 199 112 deliveries, 29 992 (2.5%) were complicated by severe maternal morbidity and 83 367 (7.0%) had adverse neonatal events. Severe maternal morbidity was associated with 2.96 times the risk of adverse neonatal events compared with no morbidity (95% CI 2.90-3.03). Associations were greatest for mothers who required assisted ventilation (RR 5.86, 95% CI 5.34-6.44), experienced uterine rupture (RR 4.54, 95% CI 3.73-5.51), or had cardiac complications (RR 4.39, 95% CI 3.98-4.84). Severe maternal morbidity was associated with ≥3 times the risk of neonatal death and hypoxic-ischemic encephalopathy and ≥10 times the risk of very preterm birth and bronchopulmonary dysplasia. CONCLUSIONS: Severe maternal morbidity is associated with an elevated risk of adverse neonatal events. Better prevention of severe maternal morbidity may help reduce burden of severe neonatal morbidity.

Impact of pregestational obesity on perinatal complications: update in a Latin American cohort.

OBJECTIVES: While the association between pregestational obesity and perinatal complications has been established, it is necessary to update the current understanding of its impact on maternal and foetal health due to its growing prevalence. Thus, this study aimed to investigate the association between pregestational obesity with the leading perinatal complications during the last 6 years. STUDY DESIGN: A cross-sectional study was performed in San Felipe, Chile. Anonymised data of 11,197 deliveries that occurred between 2015 and 2021 were included. METHODS: Pregestational body mass index was defined according to the World Health Organisation during the first trimester of pregnancy. The association between pregestational obesity and perinatal complications was analysed by calculating the odds ratio (OR), which was adjusted for confounding variables. Statistical differences were considered with a P-value of <0.05. RESULTS: The prevalence of pregestational obesity was 30.1%. Pregestational obesity was related to a high incidence of perinatal complications (≥3 complications; P < 0.0001). The main perinatal complications were caesarean section, large for gestational age (LGA), gestational diabetes (GD), macrosomia, hypertensive disorders of pregnancy (HDP), premature rupture of membranes (PROM), intrauterine growth restriction, and failed induction. Pregestational obesity was shown to be a risk factor for macrosomia (OR: 2.3 [95% confidence interval {95% CI}: 2.0-2.8]), GD (OR: 1.9 [95% CI: 1.6-2.1]), HDP (OR: 1.8 [95% CI: 1.5-2.1]), LGA (OR: 1.6 [95% CI: 1.5-1.8]), failed induction (OR: 1.4 [95% CI: 1.0-1.8]), PROM (OR: 1.3 [95% CI: 1.1-1.6]), and caesarean section (OR: 1.3 [95% CI: 1.2-1.4]). CONCLUSIONS: Pregestational obesity has been shown to be a critical risk factor for the main perinatal complications in the study population. Pregestational advice is imperative not only in preventing pregestational obesity but also in the mitigation of critical perinatal complications once they arise.

Impact of Pregestational Obesity on the Oral Health-Related Quality of Life in Brazilian Pregnant Women: A Cohort Study.

The oral health-related quality of life of pregnant women and its effects on health conditions are important topics to be investigated in scientific research. The objective of this study was to evaluate the impact of pre-pregnancy obesity on oral health-related quality of life (OHRQoL) in pregnant women. A prospective cohort study was carried out with 93 pregnant women who were evaluated in the 2nd trimester of pregnancy (T1) and after delivery (T2). The following were analyzed: dental caries (DMFT), OHRQoL (OHIP-14), anthropometric data (BMI), socioeconomic, demographic, oral hygiene behavioral habits and the use of dental services. Unadjusted and adjusted Poisson regression analyses were performed to determine the impact of predictors on OHRQoL. The results of the adjusted analysis showed lower education relative risk (RR) (1.37; 95%CI 1.02-1.83; <0.00), low income (RR 2.19; 95%CI 1.63-2.93; <0.00) and higher BMI pre-pregnancy (RR 1.03; 95% CI 1.01-1.04; <0.00) were associated with worse OHRQoL in postpartum pregnant women. Flossing was a predictor of better OHRQoL at T2 (RR 0.73; 95%CI 0.57-0.93; <0.01). Higher BMI, low education, low income and inadequate oral hygiene habits were predictors of worse OHRQOL of pregnant women after the birth of the baby.

Access to health care among female prisoners in a penitentiary in Ceará, Brazil. / Acesso e cuidado a saúde de mulheres privadas de liberdade na penitenciária cearense.

This study investigated access to health care among female prisoners in the state of Ceará, Brazil, and screened for common mental disorders. We conducted an analytical cross-sectional study in the only female prison in the state. Ninety detainees participated in the study. All participants were either pregnant or postpartum women or had one or more of the following health problems: hypertension, diabetes mellitus, tuberculosis, syphilis, hepatitis B, HIV/AIDS. The data were collected using a structured questionnaire. The findings reveal that access to health care was limited, violating the fundamental rights of the prisoners. Screening for diseases on admission to prison was limited, especially among non-pregnant women. Differences in health care were found between health conditions, with priority being given to pregnant and postpartum women. Most of the inmates (68.24%) were found to be at risk for common mental disorders (SRQ score > 7). A positive correlation was found between age and mental health problems (p = 0.0002). Despite legislation guaranteeing access to health care in prisons, the prison system is unprepared to meet the health needs of female prisoners with comorbidities and pregnant and puerperal women.

O estudo analisa o acesso ao cuidado em saúde de mulheres encarceradas no estado do Ceará, rastreando transtornos mentais comuns. Estudo analítico, transversal, de natureza quantitativa, desenvolvido na única penitenciária feminina do Ceará. Participaram 90 detentas, todas com alguma das seguintes questões de saúde: gestantes, puérperas, portadoras de hipertensão arterial sistêmica, diabetes mellitus, tuberculose, sífilis, hepatite B ou HIV/Aids. Os dados foram coletados por entrevista estruturada. Evidenciou-se acesso limitado à atenção à saúde das detentas, violando direitos básicos sob tutela do Estado. Foram constatadas limitações de exames de rastreamento de doenças nas presidiárias na ocasião de seu acesso ao cárcere, principalmente as que não se encontravam grávidas no momento do encarceramento. Houve diferenças entre as distintas condições de saúde analisadas, com prioridade da atenção às gestantes e puérperas. Entre as detentas, 68,24% apresentavam risco de transtornos mentais comuns (SRQ > 7). Houve correlação positiva entre idade e saúde mental (p = 0,0002). Embora exista legislação pertinente de garantia de acesso à saúde no cárcere, o sistema prisional está despreparado para atender às necessidades de portadoras de comorbidades, gestantes e puérperas.

Obstetrical Complications in Venezuelan Refugee and Migrant Women: Analysis of Ecuadorian National Hospital Discharge Data, 2018-2021.

An estimated 7.7 million Venezuelans have fled a severe humanitarian crisis in their country, most (70%) to other middle-income host countries in the same Andean region. Migration-related exposures during periconception and other critical gestational periods can adversely impact maternal-perinatal outcomes. Emerging evidence suggests that Venezuelan refugee and migrant women (VRMW) who migrate to Andean host countries are at-risk for delivering preterm and low birthweight infants and for Cesarean-sections. However, relatively few studies have examined obstetrical complications that could contribute to these or other short- and longer-term health outcomes of VRMW and/or their offspring. Our exploratory study analyzed four recent years of national hospital discharge data (2018-2021) from Ecuador to compare the primary discharge diagnoses of VRMW (n = 29,005) and Ecuadorian nationals (n = 1,136,796) for ICD-10 O code obstetrical complications related to or aggravated by pregnancy, childbirth, or the puerperium. Our findings indicated that VRMW were hospitalized for 0.5 days longer than Ecuadorian reference group women and they had higher adjusted odds (aOR) for a primary discharge diagnosis for obstetrical complications including preeclampsia (aOR:1.62, 95% CI:1.55,1.69), preterm labor (aOR:1.20, 95% CI:1.11,1.31), premature rupture of membranes (aOR: 1.72, 95% CI:1.63,1.83), oligohydraminos (aOR:1.24, 95% CI:1.12,1.36), obstructed labor (aOR: 1.39, 95% CI:1.31,1.47), perineal lacerations/other obstetric trauma (aOR:1.76, 95% CI:1.63, 1.91), STIs (aOR:2.59, 95% CI:1.29,2.92), anemia (aOR:1.33, 95% CI:1.24,1.42), and ectopic pregnancy (aOR:1.16 95% CI:1.04,1.28). They had similar aOR for diagnosed gestational diabetes and spontaneous abortion (SAB) compared to the reference group but a reduced aOR for genitourinary infections (aOR:0.79, 95% CI:0.74,0.84) and early pregnancy hemorrhage not ending in SAB (aOR:0.43, 95% CI:0.36,0.51). Our findings underscore the vulnerability of VRMW for a number of potentially serious obstetrical complications with the potential to adversely impact the short- and longer-term health of mothers and their offspring. Future studies should collect more detailed information on the migration status, experiences, and exposures of MRMW that influence their risk for obstetrical complications. These are needed to expand our findings to better understand why they have excess risk for these and to inform social and public health policies, programs and targeted interventions aimed at reducing the risk of this vulnerable refugee and migrant group.

Active but not quiescent lupus nephritis during pregnancy is associated with a higher rate of adverse obstetric outcomes: Analysis of a prospective cohort.

OBJECTIVE: To compare the maternal-fetal/neonatal outcome in patients with systemic lupus erythematosus (SLE) with and without lupus nephritis (LN) in remission or with active disease. METHODS: A prospective cohort of pregnant patients with SLE (ACR 1997 criteria) was studied from January 2009 to December 2021. Demographic, clinical, biochemical, and immunological variables as well as the usual maternal-fetal/neonatal complications were recorded. We compared four groups according to the status of SLE during pregnancy: patients with quiescent SLE without lupus nephritis, patients with active SLE without lupus nephritis, patients with quiescent lupus nephritis, and patients with active lupus nephritis. Statistical analysis included descriptive statistics, bivariate analysis, and Cox regression analysis. RESULTS: A total of 439 pregnancies were studied, with a median age of 28 ± 6, SLE duration of 60 months (interquartile range 36-120). A higher frequency of maternal and fetal/neonatal complications was observed in patients with active SLE with or without lupus nephritis. Multivariate analysis showed that active LN was a risk factor for gestational hypertension (hazard ratios [HR] 1.95; 95% confidence intervals [CI]: 1.01-6.39), premature rupture of membranes (HR 3.56; 95% CI: 1.79-16.05) and more frequent cesarean section (HR 1.82; 95% CI: 1.13-2.94). CONCLUSION: LN is associated with a higher frequency of maternal complications, especially in those patients with active disease during pregnancy, and those maternal complications had an impact on poor fetal/neonatal outcomes. Strict control and timely care of LN could improve the obstetric prognosis.

Prevalence of Psychoactive Substance Use During Pregnancy in Argentine Women: A Pilot Study Testing Maternal Hair.

BACKGROUND: The use of psychoactive substances (PSs) during pregnancy is a major public health concern because of their increasing prevalence worldwide. This study examined the understudied issue of gestational PS consumption in a cohort of Argentine delivering mothers. METHODS: A cross-sectional pilot study involving 51 women receiving delivery care was conducted at the Santa Rosa Hospital in La Pampa, Argentina. Information on maternal sociodemographic characteristics, pregnancy history, and drug use was obtained through standardized interviews. Maternal hair samples were analyzed for alcohol, tobacco, licit, illicit, and prescription substance biomarkers using ultra-high-performance liquid chromatography high-resolution mass spectrometry and gas chromatography mass spectrometry. RESULTS: During pregnancy, 49.0% of participants reported alcohol consumption, 25.5% reported tobacco use, and 23.5% reported cannabis use. Hair samples from 56.9% of the women were positive for illicit PSs, with the most frequent being cocaine (41.2%) and cannabis (15.7%). Among the women, 47.1% consumed alcohol during pregnancy. Of the 24 women with hair ethyl glucuronide ≥5 pg/mg, 33.3% drank until the end of gestation and 58.3% started a social drinking habit in the second half. The analysis also detected prescription substances (anticonvulsants, antidepressants, methadone, opioids, antihistamines, antiemetics, and analgesics), caffeine (70.6%), lidocaine, and levamisole, some of which were cocaine or opioid adulterants. CONCLUSIONS: This is the first study to objectively assess the consumption of licit and illicit PSs during pregnancy in Argentina. In contrast to most nearby countries, cocaine was the most detected illicit PS in this cohort of Argentine delivering women. This finding highlights the importance of regular monitoring of local trends in PS use during pregnancy.

Perinatal mortality, severe maternal morbidity and maternal near miss: protocol of a study integrated with the Birth in Brazil II survey. / Mortalidade perinatal, morbidade materna grave e near miss materno: protocolo de um estudo integrado à pesquisa Nascer no Brasil II.

Brazil presents high maternal and perinatal morbidity and mortality. Cases of severe maternal morbidity, maternal near miss, and perinatal deaths are important health indicators and share the same determinants, being closely related to living conditions and quality of perinatal care. This article aims to present the study protocol to estimate the perinatal mortality rate and the incidence of severe maternal morbidity and maternal near miss in the country, identifying its determinants. Cross-sectional study integrated into the research Birth in Brazil II, conducted from 2021 to 2023. This study will include 155 public, mixed and private maternities, accounting for more than 2,750 births per year, participating in the Birth in Brazil II survey. We will collect retrospective data from maternal and neonatal records of all hospitalizations within a 30-day period in these maternities, applying a screening form to identify cases of maternal morbidity and perinatal deaths. Medical record data of all identified cases will be collected after hospital discharge, using a standardized instrument. Cases of severe maternal morbidity and maternal near miss will be classified based on the definition adopted by the World Health Organization. The perinatal deaths rate and the incidence of severe maternal morbidity and maternal near miss will be estimated. Cases will be compared to controls obtained in the Birth in Brazil II survey, matched by hospital and duration of pregnancy, in order to identify factors associated with negative outcomes. Results are expected to contribute to the knowledge on maternal morbidity and perinatal deaths in Brazil, as well as the development of strategies to improve care.

Pre-pregnancy body mass index and caesarean section in Andean women in Peru: a prospective cohort study.

BACKGROUND: During the last two decades, Caesarean section rates (C-sections), overweight and obesity rates increased in rural Peru. We examined the association between pre-pregnancy body mass index (BMI) and C-section in the province of San Marcos, Northern Andes-Peru. METHODS: This is a prospective cohort study. Participants were women receiving antenatal care in public health establishments from February 2020 to January 2022, who were recruited and interviewed during pregnancy or shortly after childbirth. They answered a questionnaire, underwent a physical examination and gave access to their antenatal care card information. BMI was calculated using maternal height, measured by the study team and self-reported pre-pregnancy weight measured at the first antenatal care visit. For 348/965 (36%) women, weight information was completed using self-reported data collected during the cohort baseline. Information about birth was obtained from the health centre's pregnancy surveillance system. Regression models were used to assess associations between C-section and BMI. Covariates that changed BMI estimates by at least 5% were included in the multivariable model. RESULTS: This study found that 121/965 (12.5%) women gave birth by C-section. Out of 495 women with pre-pregnancy normal weight, 46 (9.3%) had C-sections. Among the 335 women with pre-pregnancy overweight, 53 (15.5%) underwent C-sections, while 23 (18.5%) of the 124 with pre-pregnancy obesity had C-sections. After adjusting for age, parity, altitude, food and participation in a cash transfer programme pre-pregnancy overweight and obesity increased the odds of C-section by more than 80% (aOR 1.82; 95% CI 1.16-2.87 and aOR 1.85; 95% CI 1.02-3.38) compared to women with a normal BMI. CONCLUSIONS: High pre-pregnancy BMI is associated with an increased odds of having a C-section. Furthermore, our results suggest that high BMI is a major risk factor for C-section in this population. The effect of obesity on C-section was partially mediated by the development of preeclampsia, suggesting that C-sections are being performed due to medical reasons.

Morphological and clinical findings in placentas and newborns with a history of tobacco, alcohol, and other substance abuse during pregnancy.

BACKGROUND: Exposure to toxins during pregnancy is the main modifiable behavior that affects the placenta and, consequently, the fetus. In particular, smoking is a recognized risk factor for negative outcomes. Our study pretended to examine gross and microscopic placental features in women who reported exposure to tobacco, alcohol, or other psychoactive substances. METHODS: In this observational case-control study, we collected 706 placentas to assess precise substance exposure histological-interaction features of in the placenta. We examined gross and microscopic placental features, and then recorded maternal and newborn clinical conditions. RESULTS: We found that 4.8% of mothers admitted to consumption of some type of (harmful) substance. The most common pre-existing maternal condition was obesity (20.3%); predominant complications included amniotic infection (32.3%), urinary tract infection (14.5%) and hypertensive disorders of pregnancy (14.5%). In newborns, we discovered positive associations as respiratory distress syndrome. Macroscopically, exposed mothers had heavier placentas, more true knots, and single umbilical artery; microscopically, they were more likely to exhibit fetal vascular malperfusion (FVM). CONCLUSIONS: Until our present study, no research linked umbilical cord defects to toxic substance exposure; our study results do confirm association with adverse outcomes in neonates and alterations in the neuro-cardio-placental circuit through FVM. IMPLICATIONS: The results are confirming the importance of this modifiable risk factor and how its presence may potentially affect the course of pregnancy, as well as the health of both mother and child.

Psychiatric disorders in pregnant women admitted to the high-risk obstetric service in a Colombian university clinic between 2013 and 2017.

OBJECTIVE: To determine the psychiatric diagnoses and treatments of patients admitted to the high-risk obstetric service who underwent a consultation with a liaison psychiatrist. METHODS: A descriptive observational study that included pregnant women from the high-risk obstetric service of a highly specialised clinic in Medellín, who had a liaison psychiatry consultation between 2013 and 2017. The main variables of interest were psychiatric and obstetric diagnoses and treatments, in addition to biopsychosocial risk factors. RESULTS: A total of 361 medical records were screened, with 248 patients meeting the inclusion criteria. The main prevailing psychiatric diagnosis was major depressive disorder (29%), followed by adaptive disorder (21.8%) and anxiety disorders (12.5%). The pharmacologic treatments most used by the psychiatry service were SSRI antidepressants (24.2%), trazodone (6.8%) and benzodiazepines (5.2%). The most common primary obstetric diagnosis was spontaneous delivery (46.4%), and the predominant secondary obstetric diagnoses were hypertensive disorder associated with pregnancy (10.4%), gestational diabetes (9.2%) and recurrent abortions (6.4%). Overall, 71.8% of the patients had a high biopsychosocial risk. CONCLUSIONS: The studied population's primary psychiatric disorders were major depressive disorder, adjustment disorder and anxiety disorders, which implies the importance of timely recognition of the symptoms of these perinatal mental pathologies, together with obstetric and social risks, in the prenatal consultation. Psychiatric intervention should be encouraged considering the negative implications of high biopsychosocial risk in both mothers and children.

Causal Pathways Between the Acute Experience of Violence During Pregnancy and Fetal Intrauterine Growth Restriction: A Cohort Study.

Introduction: Violence during pregnancy (VDP) is a prevalent global issue with dire consequences for the mother and the developing fetus. These consequences include prematurity, low birthweight, and intrauterine growth restriction (IUGR), but its pathways remain elusive. This study investigated the causal pathways between VDP and IUGR using mediation analysis. Methods: A prospective population-based birth cohort was followed from the beginning of the third gestational trimester to the second year of life. IUGR was defined by the Kramer index, and information on VDP was collected using the WHO-Violence Against Women (WHO VAW) questionnaire. Cases were considered positive only when no other life episodes were reported. Ten different mediators were analyzed as possible pathways based on previous research. Path analysis was conducted to evaluate these relationships. Results: The path analysis model included 755 dyads and presented an adequate fit. Violence during pregnancy showed a direct effect (ß = -0.195, p = 0.041) and a total effect (ß = -0.276, p = 0.003) on IUGR. Violence was associated with gestational depression or anxiety, tobacco and alcohol consumption, changes in blood pressure, and the need for emergency care, but these did not constitute mediators of its effect on IUGR. The sum of the indirect effects, however, showed a significant association with IUGR (ß = -0.081, p = 0.011). Conclusion: The acute experience of violence during pregnancy was associated with IUGR, primarily via a direct pathway. An indirect effect was also present but not mediated through the variables analyzed in this study. The robust strength of these associations underscores the negative health consequences of violence against women for the succeeding generation.

Perinatal risk factors for the onset of bipolar disorder in young adulthood: a 22-year birth cohort.

OBJECTIVE: Bipolar disorder (BD) is a major cause of disability-adjusted life years in young adults. Pregnancy complications have previously been associated with BD. The current study aimed to examine the association between perinatal factors and BD. METHODS: We included 3,794 subjects from the 1993 Pelotas population-based birth cohort study. We assessed 27 variables at birth and modeled BD onset at 18 and 22 years. Bivariate analysis was performed by means of binomial logistic regression models. The variables with p-values less than 0.05 were included in a multiple regression with confounders. RESULTS: Maternal smoking was associated with a 1.42-fold increased risk of BD at 18 or 22 years old (95%CI 1.091-1.841), and maternal passive exposure to tobacco with a 1.43-fold increased risk (95%CI 1.086-1.875). No association was found between other perinatal factors and BD after controlling for confounders. CONCLUSION: The results of the present cohort study corroborate previous reports in the literature indicating a negative effects of maternal smoking during pregnancy. These findings can be further tested and support the development of strategies to prevent the onset development of BD.

Pregnancy after kidney transplantation: 40 years single-center experience.

BACKGROUND: Kidney transplantation (KT) improves quality of life, including fertility recovery. OBJECTIVE: to describe outcomes of post-KT pregnancy and long-term patient and graft survival compared to a matched control group of female KT recipients who did not conceive. METHODS: retrospective single-center case-control study with female KT recipients from 1977 to 2016, followed-up until 2019. RESULTS: there were 1,253 female KT patients of childbearing age in the study period: 78 (6.2%) pregnant women (cases), with a total of 97 gestations. The median time from KT to conception was 53.0 (21.5 - 91.0) months. Abortion rate was 41% (spontaneous 21.6%, therapeutic 19.6%), preterm delivery, 32%, and at term delivery, 24%. Pre-eclampsia (PE) occurred in 42% of pregnancies that reached at least 20 weeks. The presence of 2 or more risk factors for poor pregnancy outcomes was significantly associated with abortions [OR 3.33 (95%CI 1.43 - 7.75), p = 0.007] and with kidney graft loss in 2 years. The matched control group of 78 female KT patients was comparable on baseline creatinine [1.2 (1.0 - 1.5) mg/dL in both groups, p = 0.95] and urine protein-to-creatinine ratio (UPCR) [0.27 (0.15 - 0.44) vs. 0.24 (0.02 - 0.30), p = 0.06]. Graft survival was higher in cases than in controls in 5 years (85.6% vs 71.5%, p = 0.012) and 10 years (71.9% vs 55.0%, p = 0.012) of follow-up. CONCLUSION: pregnancy can be successful after KT, but there are high rates of abortions and preterm deliveries. Pre-conception counseling is necessary, and should include ethical aspects.

Riesgo de depresión durante el embarazo en la atención prenatal de riesgo habitual / Risk of depression during pregnancy in usual risk antenatal care / Risco de depressão na gravidez na assistência pré-natal de risco habitual

Objetivo: identificar el riesgo de depresión durante el embarazo en gestantes de riesgo habitual incluidas en el control prenatal y los factores asociados. Método: estudio transversal, realizado con 201 gestantes, en el consultorio de prenatal de riesgo habitual de una maternidad universitaria. Para la recolección de datos se utilizó un formulario electrónico que contenía un instrumento de caracterización y la Escala de Riesgo de Depresión del Embarazo. La variable dependiente fue el riesgo de depresión en el embarazo. El análisis estadístico se realizó mediante el cálculo de la razón de posibilidades (Odds Ratio) y utilizando las pruebas de Chi-cuadrado y exacta de Fischer. Resultados: entre las participantes, 68,2% tenían mayor riesgo de depresión durante el embarazo. Hubo asociación estadísticamente significativa entre mayor riesgo de depresión durante el embarazo y la variable ocupación (p=0,04), o sea, la ausencia del trabajo (OR = 2,00) duplicó la probabilidad de ocurrencia. Conclusión: la alta prevalencia de riesgo de depresión durante el embarazo destaca la necesidad de planificación, priorización e integración de la salud mental en los servicios de salud prenatal, especialmente en el ámbito de la Atención Primaria de Salud, por parte de los gestores de salud y de los formuladores de políticas.

Objective: to identify the risk of depression during pregnancy among pregnant women receiving routine prenatal care and the associated factors. Method: a cross-sectional study, carried out with 201 pregnant women, in a routine prenatal clinic of a university maternity hospital. Data were collected using an electronic form containing a characterization instrument and the Escala de Risco de Depressão na Gravidez (Depression during Pregnancy Scale). The dependent variable was the risk of depression during pregnancy. Statistical analysis was performed by calculating the Odds Ratio and using the Chi-square and Fischer's Exact tests. Results: among the participants, 68.2% had a higher risk of depression during pregnancy. There was a statistically significant association between a higher risk of depression during pregnancy and occupation (p=0.04), that is, unemployment (OR=2.00) doubled the risk of depression. Conclusion: the high prevalence of the risk of depression during pregnancy indicates the necessity of planning, prioritizing, and integrating mental health into prenatal health services, especially in the primary healthcare environment, by health managers and policymakers.

Objetivo: identificar o risco de depressão na gravidez entre gestantes inseridas na assistência pré-natal de risco habitual e os fatores associados. Método: estudo transversal, realizado com 201 gestantes, no ambulatório de pré-natal de risco habitual de uma maternidade universitária. A coleta de dados utilizou um formulário eletrônico contendo um instrumento de caracterização e a Escala de Risco de Depressão na Gravidez. A variável dependente foi o risco de depressão na gravidez. A análise estatística deu-se pelo cálculo da razão de chances (Odds Ratio) e pelos testes Qui-quadrado e Exato de Fischer. Resultados: entre as participantes, 68,2% apresentaram maior risco de depressão na gravidez. Houve associação estatisticamente significativa entre o maior risco de depressão na gravidez e a variável ocupação (p=0,04), ou seja, a ausência de emprego (OR = 2,00) aumentou em duas vezes a chance de ocorrência. Conclusão: a alta prevalência de risco de depressão na gravidez evidencia a necessidade de planejamento, priorização e integração da saúde mental nos serviços de saúde pré-natal, principalmente no ambiente da Atenção Primária à Saúde, por parte de gestores de saúde e formuladores de políticas.
