Rudimentary horn pregnancy: clinical analysis of 12 cases and literature review / 中华妇产科杂志

Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

Expert consensus on the detection of genome-wide copy number variations in abortive tissues and family reproductive consultation / 中华医学遗传学杂志

Chromosomal aberrations including numerical abnormalities and segment duplications/deletions, as genome-wide copy number variations (CNVs), are a leading cause for spontaneous abortion. Analysis of abortive tissues for such CNVs can detect potential genomic variations in the couple and provide guidance for the choice of appropriate method to avoid further miscarriage or birth of child with chromosomal disorders. With evidence-based clinical data, an expert group jointly formed by the Genetic Disease Prevention and Control Group, Committee for Birth Defects Prevention and Control, Chinese Association of Preventive Medicine; the Clinical Genetics Group, the Society of Medical Genetics, Chinese Medical Association; the Professional Committee for Prenatal Diagnosis of Genetic Diseases, the Society of Medical Geneticists, Chinese Medical Doctor Association has discussed and formulated this consensus, with an aim to provide guidance for the application of genomic CNVs detection for the abortive tissue and genetic counseling for family reproduction.

Clinical analysis of 11 cases of pregnancy with aortic dissection / 中华妇产科杂志

Objective: To investigate the treatment and maternal and fetal outcomes of pregnant women with aortic dissection (AD). Methods: The clinical data of 11 pregnant women with AD treated at the First Affiliated Hospital of Air Force Military Medical University from January 1st, 2011 to August 1st, 2022 were collected, and their clinical characteristics, treatment plans and maternal and fetal outcomes were analyzed retrospectively. Results: (1) Clinical characteristics: the age of onset of 11 pregnant women with AD was (30±5) years old, and the week of pregnancy of onset was (31.4±8.0) weeks. Clinical manifestations: the main symptoms were sudden onset of chest and back pain or low back pain. Type of AD: 8 cases of Stanford type A, and 3 cases of type B. The aortic width was (42±11) mm. Diagnostic methods: the diagnosis of AD was confirmed by transthoracic echocardiography (TTE), computed tomography angiography (CTA) or enhanced CT examination, among which 4 cases were confirmed by CTA examination, 4 cases by TTE examination, and 3 cases by enhanced CT examination. Laboratory results: white blood cell count was (15.4±8.7) ×109/L, neutrophil count was (13.5±8.5) ×109/L, the median D-dimer level was 2.7 mg/L (2.1-9.2 mg/L), and the median fibrin degradation products level was 12.0 mg/L (5.4-36.1 mg/L). (2) Treatments: all 11 patients were admitted to hospital in emergency. Before operation, the departments of cardiac surgery, obstetrics, pediatrics and anesthesiology cooperated to develop individualized treatment plan. Aortic surgery was performed in 11 pregnant women with AD. In 6 of them, pregnancy termination was performed at the same time as aortic surgery, and aortic surgery was performed after cesarean section. Four cases of pregnancy termination and aortic operation were performed by stages, including aortic operation after cesarean section in 2 cases, and cesarean section after aortic operation in 2 cases. One case (12+6 weeks of gestation) had spontaneous abortion on the day after aortic surgery. The gestational age of the 11 patients on pregnancy termination was (32.9±7.4) weeks. Aorta surgical methods: 7 patients received under extracorporeal circulation ascending aorta replacement ± aortic valve replacement ± coronary artery transplantation (or coronary artery bypass transplantation)± left and right coronary Cabrol + total arch replacement (or aortic arch replacement)± stent implantation, 1 patient received under extracorporeal circulation aortic root replacement, and 3 patients underwent aortic endoluminal isolation. (3) Maternal and fetal outcomes: among the 11 pregnant women with AD, 9 (9/11) survived, 2 (2/11) died with lower limb ischemia before the onset of the disease. A total of 10 newborns were born in 9 pregnant women after delivery (1 of them was twins), and the 2 cases were spontaneous abortion after aortic surgery in the first trimester (12+6 weeks) and fetal death after hysterotomy in the second trimester (26+3 weeks), respectively. Among the 10 surviving neonates, 3 were full-term infants and 7 were premature infants. The birth weight of newborn was (2 651±784) g. Respiratory distress syndrome was found in 6 cases. The newborns were followed up for (5.6±3.6) years after birth, and the infants developed well during the follow-up period. Conclusions: Pregnancy complicated with AD is dangerous, and chest and back pain is the main clinical manifestation of this disease. With early identification and selection of appropriate diagnostic methods, multidisciplinary diagnosis and treatment, mother and children could obtain good outcomes.

Analysis of genetic etiology and related factors in 1 065 women with spontaneous abortions / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic etiology and related factors in 1 065 women with spontaneous abortions.@*METHODS@#All patients have presented at the Center of Prenatal Diagnosis of Nanjing Drum Tower Hospital from January 2018 to December 2021. Chorionic villi and fetal skin samples were collected, and the genomic DNA was assayed by chromosomal microarray analysis (CMA). For 10 couples with recurrent spontaneous abortions but normal CMA results for abortive tissues, non-in vitro fertilization-embryo transfer (IVF-ET) pregnancies and no previous history of live births and no structural abnormalities of the uterus, peripheral venous blood samples were collected. Genomic DNA was subjected to trio-whole exome sequencing (trio-WES). Candidate variants were verified by Sanger sequencing and bioinformatics analysis. Multifactorial unconditional logistic regression analysis was carried out to analyze the factors that may affect chromosomal abnormality in spontaneous abortions, such as the age of the couple, number of previous spontaneous abortions, IVF-ET pregnancy and history of live birth. The incidence of chromosomal aneuploidies in spontaneous abortions during the first trimester was compared in young or advanced-aged patients by chi-square test for liner trend.@*RESULTS@#Among the 1 065 spontaneous abortion patients, 570 cases (53.5%) of chromosomal abnormalities were detected in spontaneous abortion tissues, which included 489 cases (45.9%) of chromosomal aneuploidies and 36 cases (3.4%) of pathogenic/likely pathogenic copy number variations (CNVs). Trio-WES results have revealed one homozygote variant and one compound heterozygote variants in two pedigrees, both of which were inherited from the parents. One likely pathogenic variant was detected in the patient from two pedigrees. Multifactorial unconditional Logistic regression analysis suggested that age of patient was an independent risk factor of chromosome abnormalities (OR = 1.122, 95%CI: 1.069-1.177, P < 0.001), the number of previous abortions and IVF-ET pregnancy were independent protective factors for chromosomal abnormalities (OR = 0.791, 0.648; 95%CI: 0.682-0.916, 0.500-0.840; P = 0.002, 0.001), whilst the age of husband and history of live birth were not (P > 0.05). The incidence of aneuploidies in the abortive tissues has decreased with the number of previous spontaneous abortions in young patients (χ² = 18.051, P < 0.001), but was not significantly correlated with the number of previous spontaneous abortions in advanced-aged patients with spontaneous abortions (P > 0.05).@*CONCLUSION@#Chromosomal aneuploidy is the main genetic factor for spontaneous abortion, though CNVs and genetic variants may also underlie its genetic etiology. The age of patients, number of previous abortions and IVF-ET pregnancy are closely associated with chromosome abnormalities in abortive tissues.

Analysis of a Chinese pedigree affected with Meckel syndrome due to variants of TMEM67 gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic etiology for a Chinese pedigree affected with Meckel syndrome.@*METHODS@#A pedigree with a history of three consecutive adverse pregnancies which presented at the First Affiliated Hospital of Zhengzhou University on August 31, 2017 was selected as the study subject. Clinical data of the pedigree were collected. High-throughput sequencing was carried out to screen for variants of ciliopathy-related genes in the third fetus following induced abortion, and candidate variant was verified by Sanger sequencing.@*RESULTS@#The first pregnancy of the couple had ended as spontaneous abortion, whilst the fetus of the second pregnancy was suspected for having ciliopathy, though no genetic testing was carried out following elected abortion. The fetus of the third pregnancy was suspected for having ciliopathy, and high-throughput sequencing and Sanger sequencing had shown that the fetus had harbored compound heterozygous variants of the TMEM67 gene, including c.978+1G>A from the father and c.1288G>C (p.D430H) from the mother. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c.978+1G>A was classified as a pathogenic variant (PVS1+PM2_Supporting+PP5), whilst the newly discovered c.1288G>C (p.D430H) was classified as a likely pathogenic variant (PM2_Supporting+PM3+PM5+PP3).@*CONCLUSION@#The c.978+1G>A and c.1288G>C (p.D430H) compound heterozygous variants of the TMEM67 gene probably underlay the three consecutive adverse pregnancies suspected for ciliopathy in this pedigree. The discovery of c.1288G>C (p.D430H) has also expanded the mutational spectrum of the TMEM67 gene.

Anti-endothelial cell antibodies in predicting early miscarriage / 北京大学学报(医学版)

OBJECTIVE@#To explore the clinical significance of anti-endothelial cell antibodies (AECA) in predicting early miscarriage.@*METHODS@#A total of 122 pregnant women with no history of autoimmune diseases who underwent prenatal examination at Peking University People's Hospital from January 2020 to December 2022 were selected, and they were tested for AECA. Based on the history of early miscarriage (gestational age at miscarriage < 12 weeks), the participants were divided into an early miscarriage group and a control group. t-tests, non-parametric Wilcoxon tests, Chi-square tests, and Fisher's exact probability method were used to compare general information and laboratory indicators between the two groups. A multivariate Logistic regression model was used to analyze the factors associated with early miscarriage. The natural miscarriage rates were assessed through follow-up with pregnant women, and Kaplan-Meier survival analysis was employed to compare the natural miscarriage rates between AECA-positive and AECA-negative pregnant women.@*RESULTS@#(1) A total of 122 pregnant women were enrolled, comprising 35 cases (28.7%) in the early miscarriage group, with an average age of (32.1±6.1) years, and 87 cases (71.3%) in the control group, with an average age of (30.7±5.1) years. The early miscarriage group had higher gravidity [3 (2, 4) vs. 1 (1, 2), Z=-6.402, P < 0.001] and a higher prevalence of hypertension (11.4% vs.1.1%, P=0.024). The positive rate of AECA in the early miscarriage group (34.3% vs. 8.0%, χ2=13.070, P < 0.001) and the proportion of elevated immunoglobulin G (17.1% vs. 4.6%, P=0.032) were significantly higher than that in the control group. (2) Multivariate logistic regression analysis showed that higher gravidity (OR=4.149, 95%CI: 2.287-7.529, P < 0.001), AECA positivity (OR= 4.288, 95% CI: 1.157-15.893, P=0.029), and elevated immunoglobulin G levels (OR =6.177, 95%CI: 1.156-33.015, P=0.033) were risk factors for early miscarriage. (3) The 122 pregnant women were categorized into two groups: the AECA-positive group (19 cases) and the AECA-negative group (103 cases). Survival analysis demonstrated that at the end of 12 weeks of gestation, the fetal survival rate in the AECA-positive group was significantly lower than that in the AECA-negative group (84.2% vs. 96.1%, P= 0.035).@*CONCLUSION@#Higher gravidity, AECA positivity, and elevated immunoglobulin G levels are significant risk factors for early miscarriage. The results demonstrate that AECA is a novel predicting test in early miscarriage.

Analysis of pregnancy outcomes, disease progression, and risk factors in patients with undifferentiated connective tissue disease / 北京大学学报(医学版)

OBJECTIVE@#To investigate the fetal and maternal outcomes, risk factors of disease progression and adverse pregnancy outcomes (APOs) in patients with undifferentiated connective tissue disease (UCTD).@*METHODS@#This retrospective study described the outcomes of 106 pregnancies in patients with UCTD. The patients were divided into APOs group (n=53) and non-APOs group (n=53). The APOs were defined as miscarriage, premature birth, pre-eclampsia, premature rupture of membranes (PROM), intrauterine growth restriction (IUGR), postpartum hemorrhage (PPH), and stillbirth, small for gestational age infant (SGA), low birth weight infant (LBW) and birth defects. The differences in clinical manifestations, laboratory data and pregnancy outcomes between the two groups were compared. Logistic regression analysis was performed to analyze the risk factors for APOs and the progression of UCTD to definitive CTD.@*RESULTS@#There were 99 (93.39%) live births, 4 (3.77%) stillbirths and 3 (2.83%) miscarriage, 20 (18.86%) preterm delivery, 6 (5.66%) SGA, 17 (16.03%) LBW, 11 (10.37%) pre-eclampsia, 7 (6.60%) cases IUGR, 19 (17.92%) cases PROM, 10 (9.43%) cases PPH. Compared with the patients without APOs, the patients with APOs had a higher positive rate of anti-SSA antibodies (73.58% vs. 54.71%, P=0.036), higher rate of leukopenia (15.09% vs. 3.77%, P=0.046), lower haemoglobin level [109.00 (99.50, 118.00) g/L vs. 124.00 (111.50, 132.00) g/L, P < 0.001].Multivariate Logistic regression analysis showed that leucopenia (OR=0.82, 95%CI: 0.688-0.994) was an independent risk factors for APOs in UCTD (P=0.042). Within a mean follow-up time of 5.00 (3.00, 7.00) years, the rate of disease progression to a definite CTD was 14.15%, including 8 (7.54%) Sjögren's syndrome, 4 (3.77%) systemic lupus erythematosus (SLE), 4 (3.77%) rheumatoid arthritis and 1 (0.94%) mixed connective tissue disease. Multivariate Cox proportional risk regression analysis showed that Raynaud phenomenon (HR=40.157, 95%CI: 3.172-508.326) was an independent risk factor for progression to SLE.@*CONCLUSION@#Leukopenia is an independent risk factor for the development of APOs in patients with UCTD. Raynaud's phenmon is a risk factor for the progression of SLE. Tight disease monitoring and regular follow-up are the key measures to prevent adverse pregnancy outcomes and predict disease progression in UCTD patients with pregnancy.

Clinical study of modified Shirodkar transvaginal cervical cerclage during pregnancy in the treatment of cervical insufficiency / 中华妇产科杂志

Objective: To investigate the clinical efficacy of modified Shirodkar transvaginal cervical cerclage (TVCC) in the treatment of cervical insufficiency (CI) and its impact on maternal and fetal outcomes. Methods: The clinical data of 218 pregnant women with CI admitted to Fu Xing Hospital, Capital Medical University from January 1, 2015 to August 31, 2021 was retrospectively analyzed. According to different surgical approaches, they were divided into modified Shirodkar TVCC treatment during pregnancy (TVCC group, 108 cases) and non-pregnant women underwent laparoscopic cervical cerclage (LACC) treatment (LACC group, 110 cases). The clinical data and pregnancy outcomes of the two groups were compared. Furthermore, the two groups of pregnant women were stratified according to cervical length (CL) to explore the effects of the two surgical methods on the pregnancy outcomes of CI women with different CL. Results: (1) Related indicators before and during cerclage: there were no complications such as massive hemorrhage, bladder injury and anesthesia accident in the two groups of pregnant women during cerclage. Compared with the LACC group, TVCC group had longer preoperative CL [(2.3±0.6) vs (2.7±0.6) cm], more intraoperative blood loss [(7.5±0.5) vs (14.4±1.4) ml] and longer hospital stay [(6.0±0.1) vs (7.3±0.4) day]. However, the operation time was shorter [(42.9±1.6) vs (25.9±1.4) minute] and the hospitalization cost was less [(9 912±120) vs (5 598±140) yuan], and the differences were statistically significant (all P<0.05). (2) Pregnancy outcomes: live birth rates were 95.4% (103/108) in the TVCC group and 96.4% (106/110) in the LACC group, showing no significant difference between the two groups (χ2=2.211, P=0.232). The preterm birth rate (12.0%, 13/108) in the TVCC group was higher than that in the LACC group (7.3%, 8/110), the neonatal birth weight was lower than that in the LACC group [(3 006±96) vs (3 225±42) g], and the proportion of low birth weight infants was higher than that in the LACC group [15.5% (16/103) vs 1.9% (2/106)], and the differences were statistically significant (all P<0.05). (3) Stratified analysis of CL: for pregnant women with CL<2.0 cm, the miscarriage rate of the TVCC group was higher than that of the LACC group (2/9 vs 3.0%), and the live birth rate was lower than that of the LACC group (7/9 vs 97.0%), and the differences were statistically significant (all P<0.05). For CL 2.0-<2.5 cm, 2.5-<3.0 cm, CL≥3.0 cm, there were no statistically significant differences in preterm birth rate and live birth rate between the two groups (all P>0.05). Conclusions: Modified Shirodkar TVCC is simple and easy to operate, which significantly reduces the cesarean section rate and medical cost compared with LACC, and there is no significant difference in the live birth rate. When there is inevitable late abortion, laparoscopic cerclage removal does not need to be performed again, which could reduce the second operation and is worthy of clinical application.

Interaction of polycyclic aromatic hydrocarbon DNA adducts and telomere length on missed abortion / 中华预防医学杂志

Objective: To analyze the contribution and interaction of polycyclic aromatic hydrocarbons (PAH)-DNA adducts and changes of telomere length (TL) on missed abortion. Methods: From March to December 2019, patients with missed abortion in the First Hospital of Shanxi Medical University and pregnant women with normal pregnancy but voluntary abortion in the same department during the same period were selected and divided into a case group and a control group. Questionnaire was used to investigate the general situation and the pregnancy situation of the subjects. The abortion villi were collected and the content of PAH-DNA adducts and TL was detected. Logistic regression model was used to analyze the associated factors of missed abortion. R epiR package and Mediation package were used to analyze the effect and relationship between PAH-DNA adducts and TL on missed abortion. Results: The age of the subjects was(29.92±5.69)years old. The M(Q1,Q3)of PAH-DNA adducts was 453.75(404.61, 504.72) pg/ml. The M(Q1,Q3)of TL was 1.21(0.77, 1.72). The content of PAH-DNA adducts in the case group was higher than that in the control group (Z=-2.10, P=0.036), while the TL was lower than that in the control group (Z=-4.05, P<0.001). Multivariate logistic regression showed that low, medium and high levels of PAH-DNA adducts (OR=3.17,95%CI:1.41-7.14;OR=2.85,95%CI:1.25-6.52;OR=2.46,95%CI:1.07-5.64), and long, medium and short levels of TL (OR=2.50,95%CI:1.11-5.63;OR=3.32,95%CI:1.45-7.56;OR=3.22,95%CI:1.42-7.26) were all risk factors for missed abortion. The medium level of PAH-DNA adducts had a 2.76-fold higher risk of shortened TL than those with the lowest level, and no mediating role of TL was found. The stratified analysis showed that when the TL level was longer (>1.21), the low and high levels of PAH-DNA adducts were associated with missed abortion (all P<0.05); when the TL level was shorter (<1.21), the medium level of PAH-DNA adducts was associated with abortion (P=0.025). At lower levels of PAH-DNA adducts, no effect of TL on missed abortion was observed, while, at higher levels, TL was strongly associated with missed abortion (OR=7.50,95%CI:1.95-28.82;OR=6.04,95%CI:1.54-23.65;OR=9.05,95%CI:2.34-35.04). The interaction analysis found that the AP was 0.72 (95%CI: 0.46-0.99), and the SI was 5.21 (95%CI: 2.30-11.77). Conclusion: The high level of PAH-DNA adducts and shortened TL may increase the risk of missed abortion, and there may be a positive additive interaction between the two factors on missed abortion.

Pregnancy Benefit of Acupuncture on in vitro Fertilization: A Systematic Review and Meta-Analysis / 中国结合医学杂志

BACKGROUND@#Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate.@*OBJECTIVE@#To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis.@*METHODS@#Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.@*RESULTS@#A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence.@*CONCLUSION@#Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

Percepção sobre o cuidado à perda gestacional: estudo qualitativo com casais brasileiros / Perceptions on pregnancy loss care: a qualitative study with brazilian couples / Percepción sobre la atención a la pérdida del embarazo: estudio cualitativo con parejas brasileñas

Este artigo analisou a percepção e os sentimentos de casais sobre o atendimento recebido nos serviços de saúde acessados em função de perda gestacional (óbito fetal ante e intraparto). O convite para a pesquisa foi divulgado em mídias sociais (Instagram e Facebook). Dos 66 casais que contataram a equipe, 12 participaram do estudo, cuja coleta de dados ocorreu em 2018. Os casais responderam conjuntamente a uma ficha de dados sociodemográficos e uma entrevista semiestruturada, realizada presencialmente (n=4) ou por videochamada (n=8). Os dados foram gravados em áudio e posteriormente transcritos. A Análise Temática indutiva das entrevistas identificou cinco temas: sentimento de impotência, iatrogenia vivida nos serviços, falta de cuidado em saúde mental, não reconhecimento da perda como evento com consequências emocionais negativas, e características do bom atendimento. Os achados demonstraram situações de violência, comunicação deficitária, desvalorização das perdas precoces, falta de suporte para contato com o bebê falecido e rotinas pouco humanizadas, especialmente durante a internação após a perda. Para aprimorar a assistência às famílias enlutadas, sugere-se qualificação profissional, ampliação da visibilidade do tema entre diferentes atores e reorganização dos serviços, considerando uma diretriz clínica para atenção ao luto perinatal, com destaque para o fortalecimento da inserção de equipes de saúde mental no contexto hospitalar.(AU)

This study analyzed couples' perceptions and feelings about pregnancy loss care (ante and intrapartum fetal death). A research invitation was published on social media (Instagram and Facebook) and data collection took place in 2018. Of the 66 couples who contacted the research team, 12 participated in the study by filling a sociodemographic questionnaire and answering a semi-structured interview in person (n=04) or by video call (n=08). All interviews were audio recorded, transcribed, and examined by Inductive Thematic Analysis, which identified five themes: feelings of impotence, iatrogenic experiences in health services, lack of mental health care, not recognizing pregnancy loss as an emotionally overwhelming event, and aspects of good healthcare. Analysis showed experiences of violence, poor communication, devaluation of early losses, lack of support for contact with the deceased baby, and dehumanizing routines, especially during hospitalization after loss. Professional qualification, extended pregnancy loss visibility among different stakeholders, and reorganization of health services are needed to improve the care offered to grieving families, considering a clinical guideline for perinatal grief care with emphasis on strengthening the insertion of mental health teams in the hospital context.(AU)

Los hallazgos evidenciaron situaciones de violencia, comunicación deficiente, desvalorización de las pérdidas tempranas, falta de apoyo para el contacto con el bebé fallecido y rutinas poco humanizadas, especialmente durante la hospitalización tras la pérdida. Para mejorar la atención a las familias en duelo, se sugiere capacitación profesional, ampliación de la visibilidad del tema entre los diferentes actores y reorganización de los servicios, teniendo en cuenta una guía clínica para la atención del duelo perinatal, enfocada en fortalecer la inserción de los equipos de salud mental en el contexto hospitalario.(AU)

Endometrial Progesterone and Estrogen Receptors in Relation to Hormonal Levels in Women with Unexplained Recurrent Miscarriage / Receptores endometriais de progesterona e estrogênio em relação aos níveis hormonais em mulheres com aborto recorrente inexplicável

Abstract Objective Recurrent miscarriage has been linked to hormonal disturbance due to dysregulation of its receptors rather than to the availability of the hormone. We aimed to investigate endometrial expression of progesterone and estrogen receptors in relation to serum and endometrial hormonal levels in unexplained recurrent miscarriage. Methods The present case control study included 20 cases with unexplained recurrent miscarriage and 20 parous women as controls. Ovulation was confirmed using an ovulation kit and 10 to 12 days after detecting the urinary luteinizing hormone surge, all women were subjected to a blood sample and to an endometrial biopsy. Progesterone and estrogen levels were measured in serum and in endometrial tissue and receptor concentrations were in the endometrial sample. Results Women with recurrent miscarriage showed significantly lower concentration of receptors in both the cytoplasm and the nucleus of endometrial tissue compared with controls. The nuclear/cytoplasm ratio of progesterone receptor was significantly higher in cases compared with controls, implicating that recurrent miscarriage is probably linked to nongenomic activity of the hormone; this was also significant for estrogen receptor. Serum progesterone and estrogen hormonal levels were comparable between groups while both hormones were significantly reduced in the endometrium of recurrent miscarriage cases. Receptors significantly correlated with endometrial hormonal level but not to serum level. Conclusion Recurrent miscarriage might be linked to reduced endometrial progesterone and estrogen receptors and appears to be more related to nongenomic activity of progesterone. Endometrial receptors expression correlates to tissue hormonal level rather than to serum hormonal level.

Evaluation of the Effect of Low-dose Aspirin on the Prevention of Preterm Delivery in Women with a History of Spontaneous Preterm Delivery / Avaliação do efeito da aspirina em baixa dose na prevenção do parto prematuro em mulheres com história de parto prematuro espontâneo

Abstract Objective Currently, uteroplacental vascular disorders are considered one of the main mechanisms of spontaneous preterm delivery (PTD). Low-dose aspirin is used to prevent pre-eclampsia, which has a similar mechanism; hence, the present study aimed to investigate the effect of low-dose aspirin on the prevention of PTD in women with a history of spontaneous PTD. Methods The present pilot randomized clinical trial was conducted on 54 pregnant women in the aspirin group (taking 80 mg daily until the 36th week and classic treatment) and 53 patients in the control group (only receiving classic treatment). Results Forty-three patients (40%) presented before 37 weeks due to symptoms of PTL. Preterm delivery (< 37 weeks) occurred in 28 patients (26%), and there was no significant difference between the aspirin and control groups (10 patients [19%] and 18 patients [34%], respectively; p = 0.069). The time of preterm delivery was early (< 34 weeks) in 6 patients (21%), and its cause was spontaneous labor in 23 patients (82%) which was not significantly different between the two groups (p > 0.05). Out of 40 patients with spontaneous labor, 25 patients (63%) had a PTD, which was significantly lower in the aspirin group than in the control group (9 patients [45%] versus 16 patients [80%], respectively; p = 0.022). Conclusion The findings of the present study demonstrated that despite the reduction in the incidence of PTD using low-dose aspirin, the reduction rate was not statistically significant. On the other hand, in patients with spontaneous labor prone to PTD, aspirin was effective in reducing the incidence of PTD.

Resumo Objetivo Atualmente, os distúrbios vasculares uteroplacentários são considerados um dos principais mecanismos de parto prematuro espontâneo (PTD). A aspirina em baixa dose é usada para prevenir a pré-eclâmpsia, que tem um mecanismo semelhante; portanto, o presente estudo teve como objetivo investigar o efeito da aspirina em baixa dosagem na prevenção de PTD em mulheres com história de PTD espontâneo. Métodos O presente ensaio clínico piloto randomizado foi realizado em 54 gestantes do grupo aspirina (tomando 80 mg diários até a 36ª semana e tratamento clássico) e 53 pacientes do grupo controle (somente tratamento clássico). Resultados Quarenta e três pacientes (40%) apresentaram-se antes de 37 semanas devido a sintomas de PTL. O parto prematuro (< 37 semanas) ocorreu em 28 pacientes (26%) e não houve diferença significativa entre os grupos aspirina e controle (10 pacientes [19%] e 18 pacientes [34%], respectivamente; p = 0,069). O tempo de parto prematuro foi precoce (< 34 semanas) em 6 pacientes (21%) e sua causa foi trabalho de parto espontâneo em 23 pacientes (82%) que não foi significativamente diferente entre os dois grupos (p > 0,05). Das 40 pacientes com trabalho de parto espontâneo, 25 pacientes (63%) tiveram PTD, que foi significativamente menor no grupo aspirina do que no grupo controle (9 pacientes [45%] versus 16 pacientes [80%], respectivamente; p = 0,022). Conclusão Os achados do presente estudo demonstraram que, apesar da redução na incidência de DPT com o uso de aspirina em baixa dosagem, a taxa de redução não foi estatisticamente significativa. Por outro lado, em pacientes com trabalho de parto espontâneo propensas a PTD, a aspirina foi eficaz na redução da incidência de PTD.

Intervenções psicológicas necessárias: a prática como residente no serviço de medicina fetal / Necessary psychological interventions: the practice as a resident in the fetal medicine service / Intervenciones psicológicas necesarias: la práctica como residente en el servicio de medicina fetal

Com os avanços tecnológicos e o aprimoramento da prática médica via ultrassonografia, já é possível detectar possíveis problemas no feto desde a gestação. O objetivo deste estudo foi analisar a prática do psicólogo no contexto de gestações que envolvem riscos fetais. Trata-se de um estudo qualitativo sob formato de relato de experiência como psicólogo residente no Serviço de Medicina Fetal da Maternidade Escola da Universidade Federal do Rio de Janeiro (UFRJ). Os registros, feitos por observação participante e diário de campo, foram analisados em dois eixos temáticos: 1) intervenções psicológicas no trabalho em equipe em consulta de pré-natal, exame de ultrassonografia e procedimento de amniocentese; e 2) intervenções psicológicas em casos de bebês incompatíveis com a vida. Os resultados indicaram que o psicólogo nesse serviço é essencial para atuar de forma multiprofissional na assistência pré-natal para gravidezes de alto risco fetal. Ademais, a preceptoria do residente é relevante para sua formação e treinamento para atuação profissional no campo da psicologia perinatal.(AU)

Face to the technological advances and the improvement of medical practice via ultrasound, it is already possible to detect possible problems in the fetus since pregnancy. The objective of this study was to analyze the psychologist's practice in the context of pregnancies which involve fetal risks. It is a qualitative study based on an experience report as a psychologist trainee at the Fetal Medicine Service of the Maternity School of UFRJ. The records, based on the participant observation and field diary, were analyzed in two thematic axes: 1) psychological interventions in the teamwork in the prenatal attendance, ultrasound examination and amniocentesis procedure; and 2) psychological interventions in cases of babies incompatible to the life. The results indicated that the psychologist in this service is essential to work in a multidisciplinary way at the prenatal care for high fetal risk pregnancies. Furthermore, the resident's preceptorship is relevant to their education and training for professional performance in the field of Perinatal Psychology.(AU)

Embarazo ectópico abdominal de 23 semanas en primigestante. Reporte de caso / Abdominal ectopic pregnancy at 23 weeks prime pregnant. Case report

El embarazo ectópico abdominal es una patología poco frecuente, la cual consiste en un embarazo con implantación dentro de la cavidad abdominal y fuera del útero y sus anexos; siendo el menos frecuente de los embarazos ectópicos, y representando el 1 % de los casos. Sin embargo, cuando se presenta, la tasa de mortalidad materno-fetal es alta, por lo que representa una urgencia médica con complicaciones graves como hemorragia obstétrica. El diagnóstico requiere un alto grado de sospecha, debido a que el sangrado menstrual regular puede estar presente. Se presenta el caso de una paciente primigestante con embarazo ectópico abdominal en segundo trimestre, con manejo definitivo quirúrgico y posterior evolución materna favorable al postquirúrgico, sin embargo, con resultado perinatal adverso para el recién nacido. La importancia de este caso radica en su diagnóstico oportuno, por el cual se logró evitar complicaciones que pusieran en riesgo la vida de la paciente.

Abdominal ectopic pregnancy is a rare pathology, it is expressed by a pregnancy with implantation inside the abdominal cavity and outside the uterus and its annexes, being specifically the least frequent of ectopic pregnancies, representing 1% of cases. When it occurs, the maternal-fetal mortality rate is high1. The diagnosis requires a high degree of suspicion, due to regular menstrual bleeding may be present. It is a medical emergency with serious complications such as obstetric hemorrhage. We present the case of a prime pregnant patient with abdominal ectopic pregnancy in the second trimester with definitive surgical management, and subsequent maternal evolution favorable to post-surgery, however, with adverse perinatal outcome for the newborn. The importance of this case lies in its timely diagnosis, by which it was possible to avoid complications that put the patient's life at risk.

Percepções e sentimentos sobre o bebê subsequente à perda gestacional / Perceptions and feelings about the baby after pregnancy loss

A perda gestacional (PG) pode repercutir na gestação subsequente e na maternidade. Neste estudo, objetivou-se identificar e compreender as percepções e os sentimentos maternos sobre a gestação e o bebê subsequente à PG. Trata-se de estudo qualitativo e transversal, com quatro mães com PG nos últimos cinco anos, cujos bebês subsequentes tinham de 6 a 21 meses. Foram aplicados o Questionário de Dado Sociodemográficos e Clínicos, o Questionário sobre Vivências de Perda, o Brief Symptom Inventory e a Entrevista sobre Vivência de Luto Materno e Experiência da Maternidade Atual. Os resultados mostraram repercussões da PG nos sentimentos maternos sobre a gestação, como: ambivalência, medo de nova PG e angústia frente ao parto e nascimento; e nas percepções e sentimentos sobre o bebê, como: idealização das características dele e da relação mãe-bebê, medo da morte do bebê e substituição do bebê falecido. Os achados apontam a importância de ações de prevenção de saúde mental do binômio mãe-bebê em casos de PG

Efectos emocionales que causa el aborto espontáneo / Emotional effects caused by spontaneous abortion

Introducción: en el contexto mexicano la maternidad suele ser una de las prioridades de la mujer, por lo cual, cuando se interrumpe el proceso se desencadena un conjunto de emociones que le afectan de manera negativa, pudiendo limitar su actuar cotidiano. Objetivo: identificar las emociones que surgen a causa del aborto espontáneo en mujeres jóvenes. Metodología: estudio descriptivo y cualitativo. Se aplicó una escala de actitudes hacia el aborto y una entrevista semiestructurada validada por juicio de expertos. Resultados: los hallazgos evidencian tristeza, enojo y rabia, que mantienen a las participantes en estado de confusión, decepción, retraimiento, inseguridad y vacío existencial. Conclusiones: el aborto espontáneo trae como consecuencia la ruptura del ideal de la mujer, ya que esta se representa como procreadora, lo cual coincide con el perfil mexicano de la maternidad; por ende, ante un aborto ya no se cumple con la supuesta función principal de la mujer.

Introduction: In the Mexican context, motherhood is the reason for being of a woman, therefore, when the process is interrupted, a set of emotions are triggered that affect negatively, and can even limit her daily actions. Objective: To identify the emotions that arise due to spontaneous abortion in young women. Methodology: Descriptive and qualitative study. A semi-structured interview validated by expert judgment was applied. Results: The findings show sadness, anger and rage that keep the informants in a state of confusion, disappointment, withdrawal, insecurity and existential emptiness. Conclusions: Spontaneous abortion results in the rupture of the ideal of women, since this is represented as procreating, which coincides with the Mexican profile of motherhood; therefore, in the face of an abortion, the main function of the woman is no longer fulfilled.
