Antojos y aversiones alimentarias en gestantes del Conurbano Bonaerense, Argentina / Food cravings and aversions in pregnant women in the Buenos Aires Conurban, Argentina

Resumen Introducción : Las gestantes suelen experimentar aversiones y antojos alimentarios, de los cuales se cono cen poco sus características y consecuencias. El objetivo fue conocer la prevalencia de los antojos y aversiones alimentarias, las características del patrón de alimentos que son antojados o evitados y los motivos que subyacen ante su presencia. Métodos : Estudio observacional, descriptivo y trans versal. Un cuestionario validado se aplicó a 370 embara zadas y puérperas en hospitales públicos. Las variables maternas y neonatales se midieron con estadísticas descriptivas y se identificaron aquellas asociadas a los fenómenos en estudio empleando modelos de regresión logística y un análisis por clusters utilizando la técnica multivariante. Resultados : Se detectó una presencia de antojos del 71 al 80% y de aversiones del 55 al 65%. Los alimentos más antojados fueron las frutas y los alimentos dulces y los mayormente rechazados las carnes y el mate. Las características maternas predictoras de antojos fueron: tener menor edad (OR 0.94), vómitos (OR 2.23), y el haber ganado más peso de lo esperado se asoció ne gativamente con la presencia de antojos (OR 0.44). Las variables asociadas a las aversiones fueron la ausencia de antecedentes de hipertensión (OR 0.13), antecedentes de macrosomía (OR 2.70), náuseas (OR 1.86) y complica ciones durante el embarazo (OR 2.23). Discusión : Este trabajó permitió caracterizar los an tojos y aversiones alimentarias durante el embarazo y conocer su elevada frecuencia.

Abstract Introduction : Pregnant women often experience food aversions and cravings, of which little is known about their characteristics and consequences. The objective was to know the prevalence of food cravings and aver sions, the characteristics of the pattern of foods that are craved or avoided, and the reasons behind their presence. Methods : Observational, descriptive and cross-sec tional study. A validated questionnaire was applied to 370 pregnant and postpartum women in public hospi tals. Maternal and neonatal variables were measured with descriptive statistics and those associated with the phenomena under study were identified using logistic regression models and cluster analysis using the mul tivariate technique. Results : A presence of cravings from 71 to 80% and aversions from 55 to 65% was detected. The most craved foods were fruits and sweet foods and the most avoided meats and mate. The maternal characteristics predictive of cravings were: being younger (OR 0.94), vomiting (OR 2.23), and having gained more weight than expected were negatively associated with the presence of cravings (OR 0.44). The variables associated with the aversions were the absence of a history of hypertension (OR 0.13), a history of macrosomia (OR 2.70), nausea (OR 1.86) and complications during pregnancy (OR 2.23). Discussion : This work allowed to characterize food cravings and aversions during pregnancy and to know their high frequency.

Correlation analysis of serum TTR, RBP4 expressions and gestational metabolic syndrome / 中华内分泌外科杂志

Objective:To investigate the relationship between the expressions of serum trans thyroxine protein (TTR) , retinol binding protein 4 (RBP4) and metabolic syndrome of pregnancy (GMS) .Methods:A total of 103 patients with GMS from May. 2017 to Dec. 2019 were selected as the observation group, in addition, 100 healthy pregnant women with single pregnancy and no complications were selected as control group. Before pregnancy, the height and weight were detected. After the diagnosis of GMS, serum markers and blood pressure were detected. The levels of total cholesterol (TC) , triglyceride (TG) , low density lipoprotein cholesterol (LDL-C) , high density lipoprotein cholesterol (HDL-C) and fasting blood glucose (FBG) were detected by Hitachi 7600 automatic biochemical analyzer, and the expression levels of TTR and RBP4 in serum were detected by enzyme-linked immunosorbent assay (ELISA) . Receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic value of TTR and RBP4 in GMS. Multivariate Logistic regression model was used to analyze the influencing factors of GMS in pregnant women.Results:There was no significant difference in age or gestational weeks between the two groups ( P>0.05) . Compared with those in the control group, the levels of BMI, TC, TG, LDL-C, FBG, systolic blood pressure, diastolic blood pressure, serum TTR and RBP4 expression levels were higher in the observation group before pregnancy ( P<0.05) , while HDL-C was lower ( P<0.05) . The area under the curve (AUC) of TTR and RBP4 alone or combination in the diagnosis of GMS was 0.797, 0.816 and 0.898, respectively. The cut-off value of TTR was 284.91 mg/L, and the sensitivity and specificity were 63.10% and 89.00%, respectively. The cut-off value of RBP4 was 17.89 mg/L, and the sensitivity and specificity were 69.90% and 87.00%, respectively. The sensitivity and specificity of the combined diagnosis were 83.50% and 84.00% respectively. Multivariate Logistic regression analysis showed that high level of TTR and high level of RBP4 were independent risk factors of GMS in pregnant women ( P<0.05) . Conclusions:The expression levels of serum TTR and RBP4 in GMS patients are high, and they have certain diagnostic value for GMS. They are independent risk factors of GMS in pregnant women, which may provide new ideas for the early diagnosis and prevention of GMS.

Weight retention 12 months postpartum: association with sociodemographic, gestational and puerperal factors / Retenção de peso 12 meses pós-parto: associação com fatores sociodemográficos, gestacionais e puerperais

Abstract Objectives: to investigate the association between sociodemographic, gestational/puerperal factors and postpartum weight retention (PPWR) after 12 months in Brazilian women at a university hospital. Methods: prospective cohort with puerperal women recruited at the maternity ward of a university hospital in a Brazilian metropolis. At baseline (n=260), sociodemographic and anthropometric information on the mother-child binomial and data related to the gestational period were collected. Maternal dietary patterns were measured using a food frequency questionnaire and subsequently determined by Principal Component Analysis. Results: 75 women, with a mean age of 28.4 years (CI95%= 27.0-29.7), 25.3% with excessive PPPR, with an average of 3.6 kg (CI95%= 1.7) continued in the follow-up. -5.4). Higher gestational weight gain (GWG) (ß= 0.36; CI95%= 0.18-0.70) and lower maternal age (ß= -0.41; CI95%= -0.92--0.22) were PRPP predictors (p=0.001) (adjusted for per capita income, parity, type of delivery, number of prenatal visits, baby's birth weight, breastfeeding and physical activity). Conclusion: there was a high occurrence of excessive PPPR, favored by higher GPG and lower maternal age. This highlights the importance of monitoring women's health during the reproductive period, with guidance on ways of life (diet and physical activity), to favor better outcomes for mother-child.

Resumo Objetivos: investigar a associação entre fatores sociodemográficos, gestacionais/puerperais com a retenção de peso pós-parto (RPPP) após 12 meses em mulheres brasileiras em hospital universitário. Métodos: coorte prospectiva com puérperas recrutadas na maternidade do hospital universitário de uma metrópole brasileira. Na linha de base (n=260) foram coletadas informações sociodemográficas, antropométricas do binômio mãe-filho e dados relativos ao período gestacional. O padrão alimentar materno foi mensurado por meio do questionário de frequência alimentar e posteriormente determinado pela Análise de Componentes Principais. A RPPP foi classificada como risco para obesidade se ≥7,5Kg. Resultados: 75 mulheres continuaram no seguimento, com média de 28,4 anos de idade (IC95%= 27,0−29,7), 25,3% com RPPP excessiva, sendo em média 3,6 Kg (IC95%= 1,7−5,4). Maior ganho de peso gestacional (GPG) (β= 0,36; IC95%= 0,18-0,70) e menor idade materna (β= −0,41; IC95%= −0,92--0,22) foram preditores da RPPP (p≥0,001) (ajustado pela renda per capita, paridade, tipo de parto, número de consultas pré-natal, peso ao nascer do bebê, aleitamento materno e atividade física). Conclusão: evidenciou-se elevada ocorrência de RPPP excessiva, favorecida pelo maior GPG e menor idade materna. Aponta-se assim a importância do monitoramento da saúde da mulher durante o período reprodutivo, com orientações sobre modos de vida (alimentação e atividade física), para favorecer melhores desfechos para mãe-filho.

Dietary exposure level of to perfluorinated compounds and its relationship with perinatal adverse events in pregnant women in Xuhui District of Shanghai / 环境与职业医学

Background Perfluorinated compounds (PFCs) are persistent organic pollutants. Dietary exposure to PFCs among pregnant women may lead to elevated risks of adverse events during pregnancy and postpartum depression. Objective To estimate potential risk of dietary exposure to PFCs among pregnant women in Xuhui District, Shanghai, and the relationship between dietary PFCs exposure and risks of adverse events during pregnancy and postpartum depression. Methods This study was a small cohort study which recruited women residing in Xuhui District from July 2017 to September 2018. All information was collected through questionnaires by trained investigators. Basic information and dietary information were collected at the time of inclusion, where the dietary information was obtained through the Food Frequency Questionnaire (FFQ). A follow-up visit was conducted within 42 d after delivery to collect the occurrence of adverse events during pregnancy and postpartum depression. According to the results of dietary survey, sampling and PFCs level testing were conducted on commercially available staple foods, poultry and livestock meat, aquatic products, vegetables, milk and dairy products, eggs, etc. The food sampling points covered all subdistricts in Xuhui District, including farmers' markets, supermarkets, convenience stores, and shops. Daily exposure level and hazard ratio (HR) of PFCs per capita were calculated according to the dietary survey and laboratory testing. Logistic regression was used to estimate the relationship between PFCs exposure and the risks of adverse events during pregnancy and postpartum depression. The levels of PFCs exposure were further divided into 4 groups according to interquartile range, and OR and Ptrend value were calculated respectively. Results A total of 345 pregnant women were recruited in this study, whose average age was (29.61±4.92) years. Among them, 26.37% subjects reported at least one adverse event during pregnancy, and 30.14% subjects reported an Edinburgh Postnatal Depression Scale (EPDS) score ≥12. A total of 132 food samples were collected and tested, and PFCs were positive mainly in milk and dairy products, poultry meat, livestock meat, eggs, fresh water products, and sea water products. The PFCs positive rate in fresh water products was the highest, reaching 100%. The average concentration of PFCs in the positive samples was 0.018-2.10 μg·kg−1. The HR of PFCs was 4.44. A higher risk of postpartum depression was found along with a higher perfluorooctane sulfonate (PFOS) exposure level (Ptrend=0.02). Conclusion Dietary PFCs exposure may pose a health risk to pregnant women. The study findings suggest that decreasing the intake of freshwater products might help reduce the risk of PFCs exposure among pregnant women in Xuhui district, Shanghai.

Introdução: A gestação é um período em que o corpo das gestantes passa por alterações fisiológicas, entre elas maior suscetibilidade à ação de doenças infecciosas. Essas doenças são distintas quanto à prevalência, fatores associados, forma de transmissão, curso e quadro clínico, mas possuem em comum a possível manifestação de desfechos obstétricos negativos ao feto e recém-nascido quando presentes durante a gravidez. As principais doenças associadas a esses desfechos adversos são: sífilis, toxoplasmose, rubéola, citomegalovírus, HIV/Aids, tétano, infecções vaginais e do trato urinário. Objetivo: Determinar a prevalência de relato de determinadas doenças infecciosas na gestação e fatores associados em uma coorte no município de Palhoça/SC. Métodos: Estudo transversal aninhado a um estudo de coorte denominado Coorte Brasil Sul. Participarão do estudo as 558 mães de crianças cadastradas no banco de dados que contenham as informações necessárias para realização deste estudo. A análise bivariada será realizada por meio do teste do qui-quadrado, com valores de p<0,05. Já a análise multivariada será feita com todas as variáveis com valores de p<0,28 por meio da regressão de Poisson, com valor de p<0,05. Será utilizada como medida de associação a razão de prevalência com intervalo de confiança de 95%. Resultados: Entre os diversos fatores associados às infecções gestacionais, verificou-se associação estatisticamente significativa entre o relato de doenças infecciosas gestacionais e menor escolaridade materna (p=0,043) nas gestantes incluídas no estudo (n = 558). Conclusão: Gestantes com menor escolaridade apresentam maior vulnerabilidade quanto à sua saúde, sendo mais suscetíveis às infecções gestacionais.

Introduction: During pregnancy, the pregnant woman's body undergoes physiological changes, among them a greater susceptibility to infectious diseases. These diseases are distinct as to prevalence, associated factors, the form of transmission, course, and clinical picture, but they have in common the possible manifestation of negative obstetric outcomes to the fetus and newborn when present during pregnancy. The main diseases associated with these adverse outcomes are syphilis, toxoplasmosis, rubella, cytomegalovirus, HIV/AIDS, tetanus, and vaginal and urinary tract infections. Objective: To determine the prevalence of reports of certain infectious diseases in pregnancy and associated factors in a cohort in the municipality of Palhoça/SC. Methods: Cross-sectional study nested within a cohort study called the Brasil Sul Cohort. The 558 mothers of children registered in the database containing the information necessary for this study will participate in the study. The bivariate analysis will use the chi-square test, with p-values <0.05. The multivariate analysis will be done with all variables with p-values <0.28 through the Poisson regression, with p-value <0.05. The measure of association is the prevalence ratio with a 95% confidence interval. Results: Among the various factors associated with gestational infections, the study showed a statistically significant association between the report of gestational infectious diseases and lower maternal education (p=0.043) in the pregnant women included in the study (n = 558). Conclusion: Pregnant women with less education have greater vulnerability to their health, being more susceptible to gestational infections.

Expression and clinical significance of serum SFRP5 and miR-124-3p in patients with hypertension during pregnancy / 中华内分泌外科杂志

Objective:To explore the expression levels and the clinical significance of serum secreted frizzled-related protein 5 (SFRP5) and miR-124-3p in patients with hypertension during pregnancy.Methods:Ninety-eight patients with hypertension during pregnancy diagnosed from Jan. 2019 to Feb. 2022 were selected as the observation group. According to the degree of the condition of patients, they were divided into 41 cases of pregnancy hypertension, 32 cases of mild preeclampsia, and 25 cases of severe preeclampsia, and 80 healthy subjects during the same period were selected as the control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of serum SFRP5 in patients, real-time fluorescence quantitative method (qRT-PCR) was used to detect the expression level of miR-124-3p. The relationship between SFRP5, miR-124-3p levels and clinicopathological indicators in patients with hypertension in pregnancy was analyzed, Pearson correlation analysis was used to analyze the correlation between SFRP5 and miR-124-3p. Multivariate Logistic regression was used to analyze the risk factors of hypertension in pregnancy.Results:Compared with the control group, the serum SFRP5 expression level of the observation group [ (33.78±5.21) ng/L vs (43.34±8.56) ng/L] was down-regulated, while the miR-124-3p level [ (2.16±0.41) vs (1.01±0.17) ] was up-regulated, and the serum SFRP5 level of the observation group decreased with the severity of the disease[ (38.43±6.37) ng/L (33.18±5.14) ng/L (26.94±3.38) ng/L], while the level of miR-124-3p increased with the severity of the disease[ (1.62±0.24) (2.19±0.43) (3.01±0.69) ], the difference was statistically significant ( P<0.05) . The expression levels of SFRP5 and miR-124-3p in the serum of patients with hypertension in pregnancy were related to the age, pregnancy, pre-pregnancy BMI, and fasting blood glucose level of patients ( P<0.05) , but not related to the gestational age of patients ( P>0.05) . Bioinformatics TargetScan website showed that SFRP5 and miR-124-3p had binding sites. Pearson correlation analysis showed that SFRP5 and miR-124-3p were negatively correlated ( r=-0.610, P<0.05) . Multivariate Logistic regression analysis showed that SFRP5 was a protective factor for pregnancy-induced hypertension in pregnant women, and miR-124-3p was a risk factor ( P<0.05) . Conclusion:The serum levels of SFRP5 and miR-124-3p are abnormally expressed in patients with hypertension during pregnancy, and there is a certain relationship with the degree of disease. Both are involved in the occurrence and development of hypertension during pregnancy.

Effects of maternal exercise during pregnancy on neonatal weight and subcutaneous fat thickness / 环境与职业医学

Background Exercise during pregnancy is closely related to maternal and infant health. Previous studies in developed countries have linked maternal exercise during pregnancy with newborn body weight as well as subcutaneous fat thickness. However, the relevant studies in China are limited, and the conclusions remain inconsistent. Objective To investigate the effects of maternal exercise during pregnancy on neonatal weight and subcutaneous fat thickness. Methods Based on the Shanghai Birth Cohort, 959 maternal-infant pairs were included in this study. The International Physical Activity Questionnaire was used to collect average weekly frequency and daily minutes of walking in the first and second trimesters, and entropy weight method was used to calculate the cumulative exercise index in the two trimesters. Birth weight was measured using a calibrated weigh scale. Subcutaneous fat thickness was measured at abdomen, scapula, and triceps with a Harpenden skinfold caliper for all newborns and the sum of the thickness for the three sites was then calculated. A multiple linear regression model was employed to estimate the relationships of cumulative exercise index during pregnancy with neonatal body weight and subcutaneous fat thickness. Subgroup analyses stratified by pre-pregnancy body mass index (BMI) and sex of newborns were also performed. Results The mean age of pregnant women was (28.5±3.8) years, and the pre-pregnancy BMI was (21.4±3.0) kg·m−2. Newborn boys were slightly more than newborn girls (54.3% vs 45.7%), and the neonatal weight was (3374.0±427.5) g. The means of newborns' abdominal, scapular, and triceps subcutaneous fat thickness were (4.4±1.3), (5.4±1.4), and (6.0±1.5) mm, respectively, and the sum of subcutaneous fat thickness was (15.8±3.9) mm. In the first and second trimesters, 77.3% and 88.7% of pregnant women walked 4 d per week and more, respectively; the daily minutes of walking was (36.9±27.2) min and (43.3±26.3) min, respectively; the cumulative exercise index was 25.6±17.7 and 35.9±21.1, respectively. The results of multiple linear regression analysis showed that the cumulative exercise index in the second trimester was negatively associated with newborns' abdominal (b=−0.006, 95%CI: −0.010-−0.003), scapular (b=−0.005, 95%CI: −0.009-−0.002), triceps (b=−0.006, 95%CI: −0.010-−0.002), and their sum of (b=−0.018, 95%CI: −0.028-−0.007) subcutaneous fat thickness (P<0.05); in the first and second trimesters, however, the relationship between maternal cumulative exercise and newborns' body weight was not significant. The results of stratified analyses showed that the negative associations between maternal cumulative exercise index and newborns' subcutaneous fat thickness for the second trimester remained significant in the subgroups of boys and neonates whose mothers had normal pre-pregnancy BMI (P<0.05). Conclusion Cumulative exercise index in the second trimester is negatively correlated with the neonatal thickness of subcutaneous fat, and the association may be altered by neonatal sexes and maternal pre-pregnancy BMI levels.

Effect of hypertension disorders during pregnancy on umbilical cord blood hemoglobin, serum ferritin at birth and outcome in premature newborns / 中华实用儿科临床杂志

Objective:To investigate the effects of hypertensive disorders during pregnancy (HDP) on preterm newborns in terms of umbilical cord blood serum ferritin (SF), hemoglobin (Hb) at birth and outcome.Methods:Among inpatients of the First Maternity and Infant Health Hospital Affiliated to Tongji University from October 1, 2015 to December 31, 2016, totally 1 419 cases of preterm newborns were prospectively collected.Preterm infants whose mothers with diagnosis of HDP were recruited as the HDP group.Meanwhile, premature newborns whose mothers without HDP were recruited as the control group.Umbilical cord blood SF levels, Hb levels at birth, outcome of preterm newborns and the basic information for maternity were compared between the two groups.The data of normal distribution between the two groups were compared by independent sample t test.The count data was tested by χ2, and the count data with frequency <5 was tested by Fisher′ s exact test. Results:SF levels of HDP group were significantly lower than the control group [(85.6±67.2) μg/L vs. (103.9±95.5) μg/L]. But Hb levels of HDP group were much higher than the control group [(206.2±33.8) g/L vs. (193.2±31.9) g/L]. The difference between two groups was statistically significant ( t=2.791, 4.825 all P<0.05). Umbilical cord blood SF levels were negatively correlated with Hb levels at birth ( r=-0.120, P<0.001). Moreover, compared to the control group, statistically significant lower incidence of neonatal respiratory distress syndrome (NRDS), pneumonia and bronchopulmonary dysplasia (BPD) in HDP group was observed (all P<0.05). Conclusions:HDP was correlated with umbilical cord blood SF levels and Hb levels at birth in premature newborns.Higher Hb levels and relatively lower incidences of NRDS, pneumonia and BPD were observed in these newborns delivered by mothers with diagnosis of HDP.

Resumo Objetivou-se descrever as principais complicações clínicas em gestantes brasileiras relatadas na literatura, identificando os fatores de exposição mais relevantes e seus desfechos na saúde materno-infantil. Foi realizada uma revisão sistemática de artigos publicados entre 2010 e 2018. Foram incluídos três revisões e 36 artigos empíricos; transtornos mentais (n=9), doenças infecciosas (n=9) e morbidade materna grave (n=8) foram as principais complicações clínicas na gravidez. Ainda, quatro artigos enfocaram a determinação das principais afecções ou causas de internação, citando-se com maiores frequências a Infecção do Trato Urinário, a anemia e as doenças hipertensivas. Idade materna nos extremos reprodutivos, menor escolaridade, vulnerabilidade socioeconômica, características raciais e uso de serviços públicos de saúde foram os fatores de exposição mais relevantes. Resultados de saúde desfavoráveis associados a complicações clínicas na gravidez foram verificados nos oito artigos com esse perfil. A frequência de gestantes com complicações clínicas potenciais de ameaça à vida é elevada no país, evidenciando a importância da cobertura da atenção básica e a implantação de intervenções para sua redução e prevenção de desfechos maternos e infantis adversos.

Abstract The scope of this paper was to describe the main clinical complications among pregnant Brazilian women reported in the literature, identifying the most relevant exposure factors and their outcomes in maternal and child health. This is a systematic review of articles published between 2010 and 2018. Three reviews and 36 empirical articles were included; mental disorders (n=9), infectious diseases (n=9) and severe maternal morbidity (n=8) were the main clinical complications during pregnancy. In addition, four articles focused on determining the main conditions or causes of hospitalization, with a higher frequency of Urinary Tract Infection, anemia and hypertensive diseases. Maternal age at reproductive extremes, lower schooling, socioeconomic vulnerability, racial characteristics and the use of public health services were the most relevant exposure factors. Unfavorable health outcomes associated with clinical complications in pregnancy were verified in the eight articles with this profile. The frequency of pregnant women with potential life-threatening clinical complications is high in the country, highlighting the importance of primary care coverage and the implementation of interventions to reduce and prevent adverse maternal and child outcomes.

Correlation between body mass index and increased body mass during pregnancy and adverse pregnancy outcomes in elderly pregnant women / 公共卫生与预防医学

Objective To investigate the correlation between body mass index and the increase in body mass during pregnancy and adverse pregnancy outcomes in elderly pregnant women. Methods The clinical data was collected from 1,374 pregnant women who underwent regular prenatal care checkups and delivered a child at Jiangsu Maternity and Child Health Hospital from January 1, 2020 to May 1, 2020. According to the age of pregnant women, pre-pregnancy body mass index (BMI), and gestational weight gain (GWG), the subjects were divided into different groups. The incidence of adverse pregnancy outcomes between groups was compared, and the correlation between pregnant women's age, pre-pregnancy BMI and GWG and adverse pregnancy outcomes was analyzed. Results Compared with the non-advanced age group, the elderly group had an increase in the incidence rate of gestational diabetes (GDM) (38.66% VS 19.54%), the incidence rate of large for gestational age (LGA) (LGA) (19.75% VS 14.43%), and the cesarean section rate (55.46% VS) 34.77%), and the differences between the groups were statistically significant (t=40.773, 4.270, 35.630, P=0.001, 0.039, 0.001). There were no significant differences between the non-advanced age group and the elder group in the incidence of pregnancy-induced hypertension (PIH) (10.92% VS 8.63%), the incidence of small for gestational age (2.52% VS 2.90%), and the incidence of neonatal asphyxia ( 2.10% VS 1.23%) (t=1.265, 0.105, 1.088, P=0.261, 0.746, 0.297). ). The incidence of GDM in overweight and obese elderly pregnant women was higher than that in underweight and normal pregnant women. The incidence of GDM in the elderly pregnant women with less GWG and excessive GWG was higher than that in the normal group (P<0.05). Conclusion The pre-pregnancy body mass index and the gain in body mass during pregnancy are related to the occurrence of adverse pregnancy outcomes. It is necessary to strengthen the monitoring and management of pre-pregnancy body mass index and pregnancy body quality in elderly pregnant women.

Effects of chronic stress during pregnancy on sex-specific offspring emotional damage / 环境与职业医学

Background Studies have shown that stress during pregnancy can affect the growth and development of fetuses and offspring, and this effect has sex differences, but the results are controversial, and there are few studies on the emotional damage of offspring of different sexes caused by stress during pregnancy. Objective This experiment is designed to observe the effect of chronic stress during pregnancy on emotional damage of offspring of different sexes. Methods Thirty-two SD female rats were randomly divided into a model group and a control group (16 rats in each group), 24 male rats were divided into a model mating group (n=16) and a control mating group (n=8). Each rat of the model group was reared in a single cage and received chronic unpredictable mild stress (CUMS) for 28 d, including hot water swimming for 5 min, cold water swimming for 5 min, tail pinching for 2 min, crowding for 24 h, moist bedding for 24 h, cage shaking for 30 min, and space restriction for 2 h. One stressor was administered daily and the same stressor did not repeat within 7 d. Blood was collected from the endocanthal vein of the two groups of female rats 1 d before and 1, 7, 14, 21, and 28 d after stress, the plasma was separated by centrifugation, and 131I radioimmunoassay was used to measure plasma corticosterone concentration. On postnatal day 21 (PND21), 16 offspring rats (half male and half male) were randomly selected from each group, their plasma corticosterone concentration was measured on PND28 and PND42, and their emotional damage was measured on PND42. Results The plasma corticosterone levels of dams in the model group on the 14th, 21th, and 28th days of stress [(394.02±97.40), (444.12±90.43), and (463.71±107.75) μg·L−1] were higher than those in the control group [(285.63±81.64), (341.78±48.39), and (320.42±84.76) μg·L−1] (all P< 0.05). On PND28 and PND42, the plasma corticosterone levels in the female model offspring group [(543.30±90.21) and (530.76±83.10) μg·L−1] were higher than those in the female control offspring group [(397.77±64.27) and (325.78±61.03) μg·L−1] (both P<0.05). In the sugar water preference test, the total fluid consumption [(10.74±1.28) mL], sugar water consumption [(5.50±1.30) mL], and 1% sucrose preference percentage [(20.36±3.41) %] in the female model offspring group were lower than those in the female control offspring group [(13.74±2.06) mL, (8.56±2.04) mL, and (62.11±8.05) %] (all P<0.05). In the open field test, the horizontal score, vertical score, and cleaning times of the male model offspring group were lower than those of the male control offspring group (all P<0.05). In the tail suspension test, the immobility time of the female and male model offspring groups [(126.95±39.88) and (70.24±28.98) s] was longer than the control offspring groups of the same sex [(54.30±24.99) and (38.63±18.91) s] (both P<0.05), and the duration of immobility time in the female model offspring group was longer (t=3.253, P=0.006). In the forced swimming test, the immobility time of the female model offspring group [(7.97±6.66) s] was longer than that of the female control offspring group [(1.85±2.12) s] (t=2.478, P=0.037). On PND42, the plasma corticosterone level of female offspring was negatively correlated with total fluid consumption, sugar water consumption, and 1% sucrose preference percentage (r=−0.621, r=−0.728, r=−0.699; P<0.05), and positively correlated with immobility time in the tail suspension test and immobility time in the forced swimming test (r=0.571, r=0.712; P<0.05), However, there was no correlation between plasma corticosterone and emotional indicators on PND42 in male offspring (P>0.05). Conclusion Chronic stress during pregnancy causes emotional damage to the offspring, and female offspring show depression-like behaviors.

Uterine torsion in pregnancy, expect the unexpected: case report

Uterine torsion in pregnancy is a rare condition, but potentially life-threatening. The non-specific clinical features make preoperative diagnosis difficult and most cases are discovered during caesarean deliveries done for other obstetric indications. Authors present 2 cases of uterine torsion with different clinical presentation and outcome. Case 1 was a G3P2 at 36 weeks with twin pregnancy presented in active labour with a prolapsed cord. A 180 degrees uterine torsion was discovered only after delivery of the foetuses, resulting in inadvertent posterior uterine wall incision. Case 2 was a G6P5 at 35 weeks who presented with an acute abdomen and went into shock. At laparotomy, a 360 degrees uterine torsion was discovered complicated with placental abruption, causing a fresh stillborn baby. These cases highlight uterine torsion as a rare but important diagnosis in obstetrics, which could be associated with potentially devastating outcome.

Comparative maternal outcomes of oral nifedipine and intravenous labetalol for severe hypertension during pregnancy: an open label randomized controlled trial

Background: Hypertensive diseases are commonly seen during pregnancy and remain one of the leading causes of maternal morbidity and mortality. Mostly commonly preferred drugs by health care providers for treatment of severe hypertension during pregnancy are labetalol and hydralazine. However, they require proper storage, intravenous access, and adequately trained staff for usage. Oral nifedipine in contrast is easier to use and widely available.  Objective of this study was to report the efficacy and safety of oral nifedipine as compared to intravenous labetalol for treatment of severe hypertension during pregnancy.Methods: It was an open label randomized controlled trial in which 100 women with severe hypertension during pregnancy were enrolled. They were randomized to receive either incremental doses of intravenous labetalol every 20 minutes (total 300 mg) or 10 mg oral nifedipine every 20 minutes (up to 50 mg) to lower the blood pressure to safer levels.Results: Women receiving oral nifedipine took significantly less time to achieve target blood pressure [(37.6±23.3) minutes (SD) as compared to those receiving intravenous labetalol (52.0 minutes±27.95 (SD)]. Women receiving nifedipine for treatment also required significantly lesser doses to control the blood pressure [mean dose 1.8±1.1 (SD) versus 2.6±1.2 (SD) p=0.006]. There were two failures in labetalol group and one failure in nifedipine group. No serious adverse events were reported in either group.Conclusions: Oral nifedipine is equally efficacious to I.V. labetalol for treatment of severe hypertension during pregnancy and is easier to use in low resource settings.

Conclusión: Las características maternas asociadas al diagnóstico de macrosomía fetal son parto postérmino, diabetes gestacional, ganancia de peso excesiva y sexo del recién nacido.

Objective: To identify the maternal characteristics associated with the diagnosis of fetal macrosomia at Sergio E. Bernales Hospital from January to December 2018. Methods: An observational, analytical, retrospective, case-control study was carried out. The population studied was pregnant women with a diagnosis of fetal macrosomia treated in the gynecoobstetrics service of Sergio E. Bernales Hospital from January to December 2018. Through a data collection sheet, the information from the medical records was extracted; the data was then processed according to the IBM SPSS Statistics v25 program. Results: Of 532 patients studied, 133 cases and 399 controls were obtained. Maternal age varies between 14 and 45 years (average age of 27.01). A statistically significant association was found between fetal macrosomia and the following variables: post-term pregnancy (OR = 13,613 95% CI 2,901-63,891), gestational diabetes (OR 5.7 IC95% 2.5 -12.7), excessive weight gain (OR 1,833 95% CI 1,154-2,911), sex of the newborn (OR 1.83 95% CI 1.2-2.7) and age of the mother (OR 1.7 95% CI 1.0-2.9). When performing the multivariate analysis, no association was found with the variables age of the mother (P = 0.228, OR 1.510 95% CI 0.773-2.950) and BMI (P = 0.331, OR 0.740 95% CI 0.403-1.358), so they were considered confusing variables. Conclusion: The maternal characteristics associated with the diagnosis of fetal macrosomia are post-term delivery, gestational diabetes, excessive weight gain and sex of the newborn.

Correlation between Dental Pulps Pain and Hormonal Changes during Pregnancy- A Clinical Investigation

The hormonal and physiological changes that come with pregnancy are unique. The aim of this clinical investigation was to observe a correlation between dental pulpal pain and hormonal changes during pregnancy. Methods: Out of hundred pregnant females examined seventy four females were having tooth or teeth indicative of either pulpal therapy or root canal treatment (RCT). On explaining their dental status forty pregnant females with no pain or mild pain agreed to take dental treatment, they were grouped as Group A and the remaining thirty-four who were reluctant and refused dental treatment were classified in Group B. Results: In Group A, thirty-five pregnant got their dental treatment completed along with regular Obstetrics & Gynecological (Obs&Gyne) follow up. In Group B, twenty- four pregnant females were on regular Obstetric & Gynecological follow up and ten of them even did not turned up for either. In Group B twentytwo pregnant females turned back to seek dental treatment due to pain, inflammation or inability to chew food during third trimester which were pain free earlier. In Group A, three out of five also came back for dental treatment. All the data collected was subjected to statistical analysis using paired-t test and Pearson r correlation test. Conclusion: Significant difference was observed with reduced pain threshold during third trimester and +1 coefficient was found stating a significant relationship between dental pulpal pain and raised levels of estrogen and progesterone during pregnancy.
