RESUMO

OBJECTIVE: The serum ischemia modified albumin (IMA), biglycan, and decorin levels of pregnant women who were hospitalized for threatened preterm labor were measured. METHODS: Fifty-one consecutive pregnant women with a single pregnancy between the 24th and 36th weeks with a diagnosis of threatened preterm labor were included in the present prospective cohort study. RESULTS: As a result of multivariate logistic regression analysis for predicting preterm delivery within 24 hours, 48 hours, 7 days, 14 days, ≤ 35 gestational weeks, and ≤ 37 gestational weeks after admission, area under the curve (AUC) (95% confidence interval [CI[) values were 0.95 (0.89-1.00), 0.93 (0.86-0.99), 0.91 (0.83-0.98), 0.92 (0.85-0.99), 0.82 (0.69-0.96), and 0.89 (0.80-0.98), respectively. In the present study, IMA and biglycan levels were found to be higher and decorin levels lower in women admitted to the hospital with threatened preterm labor and who gave preterm birth within 48 hours compared with those who gave birth after 48 hours. CONCLUSION: In pregnant women admitted to the hospital with threatened preterm labor, the prediction preterm delivery of the combined model created by adding IMA, decorin, and biglycan in addition to the TVS CL measurement was higher than the TVS CL measurement alone. CLINICAL TRIAL REGISTRATION: The present trial was registered at ClinicalTrials.gov, number NCT04451928.


OBJETIVO: Medir os níveis séricos de albumina modificada por isquemia (IMA), biglicano e decorina de gestantes hospitalizadas por ameaça de parto prematuro. MéTODOS: Cinquenta e uma mulheres grávidas consecutivas com uma única gravidez entre a 24ª e a 36ª semanas com diagnóstico de ameaça de trabalho de parto prematuro foram incluídas no presente estudo de corte prospectivo. RESULTADOS: Como resultado da análise de regressão logística multivariada para prever parto prematuro dentro de 24 horas, 48 horas, 7 dias, 14 dias, ≤ 35 semanas gestacionais e ≤ 37 semanas gestacionais após a admissão, área sob a curva (AUC) (95% de confiança os valores de intervalo [CI[) foram 0,95 (0,89­1,00), 0,93 (0,86­0,99), 0,91 (0,83­0,98), 0,92 (0,85­0,99), 0,82 (0,69­0,96) e 0,89 (0,80­0,98), respectivamente. No presente estudo, os níveis de IMA e biglican foram maiores e os níveis de decorin menores em mulheres admitidas no hospital com ameaça de trabalho de parto prematuro e que tiveram parto prematuro em 48 horas em comparação com aquelas que deram à luz após 48 horas. CONCLUSãO: Em gestantes admitidas no hospital com ameaça de trabalho de parto prematuro, a predição de parto prematuro do modelo combinado criado pela adição de IMA, decorin e biglican, além da medição do TVS CL, foi maior do que a medição do TVS CL isoladamente. REGISTRO DO ENSAIO CLíNICO: O presente ensaio foi registrado em ClinicalTrials.gov, número NCT04451928.

RESUMO

OBJECTIVE: Hyperemesis gravidarum (HG) is a pregnancy complication that can progress with persistent nausea and vomiting. The aim of the present study is to evaluate the relationship between hematological parameters and HG. METHOD: A total of 532 pregnant women with HG who were admitted to the Department of Obstetrics and Gynecology between March 2019 and February 2021, and 534 healthy pregnant women with characteristics similar to those of the case group were included in the study. The hematological parameters of both groups were compared. In addition, the hematological parametersof patients with HG according to the severity of ketonuria were compared. RESULTS: The mean age of the HG group (n = 532) was 26.3 ± 4.1 years, and that of the control group (n = 534) was 25.9 ± 4.8 years. Among patients with HG, 46% (n = 249) had ketone (+), 33% (n = 174), ketone (++), and 21% (n = 109), ketone (++ + ). The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were higher in the HG group than in the control group: 3.8 (2.8-5.8)/3.2 (2.6-4.0); p < 0.001; and 135.2 ± 30.4/108.9 ± 62.2; p < 0.001 respectively. The neutrophil count, NLR, and PLR were higher in the group with ketone (++ + ) than in the groups with ketone (+) or ketone (++): 7.6 ± 1.9/5.5 ± 2.4; p < 0.001; 3.8(2.8-4.6)/2.9(2.3-3.6); p < 0.001; and 149.9 ± 48.0/135.9 ± 65.7; p < 0.001 respectively. The mean corpuscular hemoglobin (MCH) level, the NLR, and the PLR were identified as independent predictors of the presence of HG and the level of ketone positivity in HG patients. CONCLUSION: The NLR and PLR were high in patients with HG, suggesting the its inflammatory activity. They may be important markers associated with the presence and severity of HG.


OBJETIVO: A hiperêmese gravídica (HG) é uma complicação da gravidez que pode evoluir com náuseas e vômitos persistentes. O objetivo deste estudo é avaliar a relação entre os parâmetros hematológicos e a HG. MéTODO: Foram incluídas neste estudo 532 gestantes com HG internadas no Departamento de Obstetrícia e Ginecologia entre março de 2019 e fevereiro de 2021, e 534 gestantes saudáveis com características semelhantes às do grupo de caso. Os parâmetros hematológicos foram comparados entre gestantes com e sem HG. Além disso, os parâmetros hematológicos foram comparados entre as pacientes com HG de acordo com a gravidade da cetonúria. RESULTADOS: A média de idade do grupo GH (n = 532) foi de 26,3 ± 4,1 anos, e a do grupo de controle (n = 534) foi de 25,9 ± 4,8 anos. Entre as pacientes com HG, 46% (n = 249) tinham cetona(+), 33% (n = 174), cetona(++), e 21% (n = 109), cetona(+ + +). A razão de neutrófilos para linfócitos (RNL) e a razão de plaquetas para linfócitos (RPL) foram maiores no grupo HG do que no grupo de controle: 3,8 (2,8­5,8)/3,2 (2,6­4,0); p < 0,001; e 135,2 ± 30,4/108,9 ± 62,2; p < 0,001, respectivamente). A contagem de neutrófilos, a RNL e a RPL foram maiores no grupo com cetona(++ + ) do que nos grupos com cetona(+) e cetona(++): 7,6 ± 1,9/5,5 ± 2,4; p < 0,001; 3,8 (2,8­4,6)/2,9 (2,3­3,6); p < 0,001; e 149,9 ± 48,0/135,9 ± 65,7; p < 0,001, respectivamente. O nível médio de hemoglobina corpuscular (MHC), a RNL e a RPL foram identificados como preditores independentes da presença de HG e do nível de positividade de cetona em pacientes com HG. CONCLUSãO: A RNL e RPL estavam elevadas em pacientes com HG, o que sugere a sua atividade inflamatória. Elas podem ser marcadores importantes associados à presença e à gravidade da HG.

RESUMO

OBJECTIVE: Missed abortion occurs in ∼ 15% of all clinical pregnancies. The pathogenesis is not clearly known. However, defective placentation resulting in maternal systemic inflammatory response is considered responsible for missed abortion. Platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) are increasingly cited parameters of inflammation in the literature. However, no study evaluated the PLR and NLR rates in missed abortions so far. The aim of the present study is to investigate whether complete blood count (CBC) inflammatory parameters such as NLR and PLR are increased in patients with missed abortion. METHODS: Medical records of 40 pregnant women whose gestation ended in missed abortion at between 6 and14 weeks of gestation and of 40 healthy pregnant women were collected and compared retrospectively. The groups were compared regarding hemoglobin, hematocrit, platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), PLR and NLR. RESULTS: Platelet distribution width, NLR and PLR values were higher in the missed abortion group compared with the healthy pregnant women group (rates are p = 0.043; p = 0.038; and p = 0.010, respectively). Hematocrit, MPV, and lymphocyte values were found to be lower in the missed abortion group compared with the healthy pregnant women group (p = 0.027, p = 0.044 and p = 0.025, respectively). CONCLUSION: The PDW, NLR and PLR values of the missed abortion group were reported high; and MPV values were reported low in the present study. These findings may help to speculate a defective placentation in the pathogenesis of missed abortion.

RESUMO

Placenta accreta syndromes are associated with increased maternal mortality and morbidity. Cesarean hysterectomy is usually performed in cases of placenta accreta syndrome. Fertility sparing methods can be applied. In the present study, we report a successful segmental uterine resection method for placenta accreta in the anterior uterine wall in a cesarean section case. A 39-year-old woman underwent an elective cesarean section at 38 + 2 weeks. A placental tissue with an area of 10 cm was observed extending from the anterior uterine wall to the serosa, 2 cm above the uterine incision line. The placental tissue was removed with the help of monopolar electrocautery. The uterine incision was continuously sutured. The patient was discharged on the second postoperative day. The placental pathology was reported as placenta accreta. The American College of Obstetricians and Gynecologists (ACOG) generally recommends cesarean section hysterectomy in cases of placenta accreta because removal of placenta associated with significant hemorrhage. Conservative and fertility sparing methods include placenta left in situ, cervical inversion technique and triple-P procedure. There are several studies reporting that segmental uterine resection is performed with and without balloon placement or artery ligation. Segmental uterine resection may be an alternative to cesarean hysterectomy to preserve fertility or to protect the uterus in cases of placenta accreta when there is no placenta previa.
