Abstract

Objective: Stillbirth is a potentially preventable complication of pregnancy. Identifying women at high risk of stillbirth can guide decisions on the need for closer surveillance and timing of delivery in order to prevent fetal death. Prognostic models have been developed to predict the risk of stillbirth, but none has yet been validated externally. In this study, we externally validated published prediction models for stillbirth using individual participant data (IPD) meta-analysis to assess their predictive performance. Methods: MEDLINE, EMBASE, DH-DATA and AMED databases were searched from inception to December 2020 to identify studies reporting stillbirth prediction models. Studies that developed or updated prediction models for stillbirth for use at any time during pregnancy were included. IPD from cohorts within the International Prediction of Pregnancy Complications (IPPIC) Network were used to validate externally the identified prediction models whose individual variables were available in the IPD. The risk of bias of the models and cohorts was assessed using the Prediction study Risk Of Bias ASsessment Tool (PROBAST). The discriminative performance of the models was evaluated using the C-statistic, and calibration was assessed using calibration plots, calibration slope and calibration-in-the-large. Performance measures were estimated separately in each cohort, as well as summarized across cohorts using random-effects meta-analysis. Clinical utility was assessed using net benefit. Results: Seventeen studies reporting the development of 40 prognostic models for stillbirth were identified. None of the models had been previously validated externally, and the full model equation was reported for only one-fifth (20%, 8/40) of the models. External validation was possible for three of these models, using IPD from 19 cohorts (491 201 pregnant women) within the IPPIC Network database. Based on evaluation of the model development studies, all three models had an overa

Abstract

Objective Stillbirth is a potentially preventable complication of pregnancy. Identifying women at high risk of stillbirth can guide decisions on the need for closer surveillance and timing of delivery in order to prevent fetal death. Prognostic models have been developed to predict the risk of stillbirth, but none has yet been validated externally. In this study, we externally validated published prediction models for stillbirth using individual participant data (IPD) meta-analysis to assess their predictive performance. Methods MEDLINE, EMBASE, DH-DATA and AMED databases were searched from inception to December 2020 to identify studies reporting stillbirth prediction models. Studies that developed or updated prediction models for stillbirth for use at any time during pregnancy were included. IPD from cohorts within the International Prediction of Pregnancy Complications (IPPIC) Network were used to validate externally the identified prediction models whose individual variables were available in the IPD. The risk of bias of the models and cohorts was assessed using the Prediction study Risk Of Bias ASsessment Tool (PROBAST). The discriminative performance of the models was evaluated using the C-statistic, and calibration was assessed using calibration plots, calibration slope and calibration-in-the-large. Performance measures were estimated separately in each cohort, as well as summarized across cohorts using random-effects meta-analysis. Clinical utility was assessed using net benefit. Results Seventeen studies reporting the development of 40 prognostic models for stillbirth were identified. None of the models had been previously validated externally, and the full model equation was reported for only one-fifth (20%, 8/40) of the models. External validation was possible for three of these models, using IPD from 19 cohorts (491 201 pregnant women) within the IPPIC Network database. Based on evaluation of the model development studies, all three models had an overall high risk of bias, according to PROBAST. In the IPD meta-analysis, the models had summary C-statistics ranging from 0.53 to 0.65 and summary calibration slopes ranging from 0.40 to 0.88, with risk predictions that were generally too extreme compared with the observed risks. The models had little to no clinical utility, as assessed by net benefit. However, there remained uncertainty in the performance of some models due to small available sample sizes. Conclusions The three validated stillbirth prediction models showed generally poor and uncertain predictive performance in new data, with limited evidence to support their clinical application. The findings suggest methodological shortcomings in their development, including overfitting. Further research is needed to further validate these and other models, identify stronger prognostic factors and develop more robust prediction models. (c) 2021 The Authors.

Abstract

Background: The kidney-brain interaction has been a topic of growing interest. Past studies of the effect of kidney function on intracerebral hemorrhage (ICH) outcomes have yielded inconsistent findings. Although the second, main phase of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT2) suggests the effectiveness of early intensive blood pressure (BP) lowering in improving functional recovery after ICH, the balance of potential benefits and harms of this treatment in those with decreased kidney function remains uncertain. Study Design: Secondary analysis of INTERACT2, which randomly assigned patients with ICH with elevated systolic BP (SBP) to intensive (target SBP < 140 mm Hg) or contemporaneous guideline-based (target SBP < 180 mm Hg) BP management. Setting & Participants: 2,823 patients from 144 clinical hospitals in 21 countries. Predictors Admission estimated glomerular filtration rates (eGFRs) of patients were categorized into 3 groups based on the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine equation: normal or high, mildly decreased, and moderately to severely decreased (>90, 60-90, and <60 mL/min/1.73 m2, respectively). Outcome(s): The effect of admission eGFR on the primary outcome of death or major disability at 90 days (defined as modified Rankin Scale scores of 3-6) was analyzed using a multivariable logistic regression model. Potential effect modification of intensive BP lowering treatment by admission eGFR was assessed by interaction terms. Result(s): Of 2,623 included participants, 912 (35%) and 280 (11%) had mildly and moderately/severely decreased eGFRs, respectively. Patients with moderately/severely decreased eGFRs had the greatest risk for death or major disability at 90 days (adjusted OR, 1.82; 95% CI, 1.28-2.61). Effects of early intensive BP lowering were consistent across different eGFRs (P = 0.5 for homogeneity). Limitation(s): Generalizability issues arising from a clinical tri

Abstract

Objetivo: Determinar si la condición clínica periodontal materna, el índice de masa corporal (IMC) y su variación durante el embarazo, se asocian con marcadores de inflamación sistémica: interleuquina-6 (IL-6), factor de necrosis tumoral alfa (TNF-) y proteína C reactiva (PCR) a nivel plasmático. Material y Método: Estudio clínico que analizó una cohorte de 56 embarazadas entre 18 y 38 años de edad (promedio 27.9 ± 7.04 años), derivadas de la unidad de medicina perinatal en el centro de salud docente asistencial (CESA) de la Universidad de los Andes. Todas ellas consintieron voluntariamente su participación en el estudio. En cada trimestre de embarazo, se les realizó un examen periodontal completo, consistente en la determinación de los niveles de inserción clínica, profundidad al sondaje, índice de higiene y sangrado en seis sitios por cada pieza dentaria, excluyendo terceros molares. Adicionalmente, en cada control se obtuvieron muestras de sangre periférica para la determinación de los mediadores proinflamatorios mediante técnica de ELISA. El diagnóstico periodontal y los niveles de mediadores inflamatorios fueron relacionados con la variación del IMC durante el embarazo. Resultados: Las embarazadas con periodontitis crónica presentaron una mayor variación y aumento del índice de masa corporal (p=0.039) y niveles de IL-6 (p=0.026) en comparación con las mujeres embarazadas con gingivitis. Conclusiones: En esta serie de pacientes, se demostró una asociación entre el diagnóstico clínico de periodontitis durante el embarazo con un aumento plasmático de IL-6, así como también una asociación entre un aumento del IMC con los niveles plasmáticos de PCR. Objective: To determine if maternal periodontal clinical status, body mass index (BMI) and its variation during pregnancy are associated with increased levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-) and C-reactive protein (CRP) in plasma. Material and Methods: This clinical study included a total of 56 pregnant women between 18 and 38 years old (mean 27.9 ± 7.04 years), referred from perinatal medicine unit at health care center Universidad de los Andes. All pregnant patients consented to voluntarily participate in the study. In each trimester of pregnancy, they underwent a complete periodontal examination, involving the determination of clinical attachment levels, probing depth, bleeding and hygiene index at six sites of each tooth, excluding third molars. Additionally, in each clinical check, peripheral blood samples were taken for determination of pro-inflammatory mediators with ELISA immunoassay. Periodontal diagnosis and inflammatory mediators were the variables analyzed in relation to changes in BMI during pregnancy. Results: Pregnant women with chronic periodontitis had an increase and more variation of BMI (p=0.039) and higher levels of IL-6 (p=0.026) in comparison with pregnant women with gingivitis. Conclusions: In this series of pregnant patients the clinical diagnosis of periodontitis, with an increase in BMI are associated with increased plasma levels of IL-6 and CRP.

Abstract

Blood hemoglobin, serum iron, total iron binding capacity (TIBC) and serum ferritin were measured in 140healthy rural mapuche (southern Chile's indigenous ethnic group) infants aged 8 to 15 months: 90 had been ex-clusively breast fed for the first 5 or 6 months of life, then solid foods were introduced but cow's milk was nevergiven to them. The remaining 50, which were all weaned at nearly 4 months of age and then given cow's milk andsolid foods at the corresponding age, were designated as controls. Anemia was detected in 4.5% of breast fedinfants and in 38% of controls. Evidence of iron deficient erythropoyesis was found in 5% and 81% of cases andcontrols, respectively. Human milk apparently protects this ethnic group from iron deficiency anemia and thisprotection seems to be better in mapuche infants than in other groups of Chilean infants, because these late haveshowTi 30% incidence of anemia around the first year of life in other studies. More studies on differences in ironnutritional state among mapuche and non mapuche are needed and are under way.(Key word*: iron nutrition, iron defficiency, anemia, breast feeding, cow's milk, mapuche.)

Abstract

Objectives: To determine the accuracy with which uterine artery Doppler in the first trimester of pregnancy predicts pre-eclampsia and fetal growth restriction, particularly early-onset disease. Methods: We searched MEDLINE (1951-2012), EMBASE (1980-2012) and the Cochrane Library (2012) for relevant citations without language restrictions. Two reviewers independently selected studies that evaluated the accuracy of first-trimester uterine artery Doppler to predict adverse pregnancy outcome and performed data extraction to construct 2 × 2 tables. We synthesized sensitivity and specificity for various Doppler indices using a bivariate random-effects model. Results: From 1866 citations, we identified 18 studies (55,974 women). The sensitivity and specificity of abnormal uterine artery flow velocity waveform (FVW) in the prediction of early-onset pre-eclampsia were 47.8% (95% CI: 39.0-56.8) and 92.1% (95% CI: 88.6-94.6), and in the prediction of early-onset fetal growth restriction were 39.2% (95% CI: 26.3-53.8) and 93.1% (95% CI: 90.6-95.0), respectively. The sensitivities for predicting any pre-eclampsia and fetal growth restriction were 26.4% (95% CI: 22.5-30.8) and 15.4% (95% CI: 12.4-18.9), respectively, and the specificities were 93.4% (95% CI: 90.4-95.5%) and 93.3% (95% CI: 90.9-95.1), respectively. The number needed to treat (NNT) with aspirin to prevent one case of early-onset pre-eclampsia fell from 1000 to 173 and from 2500 to 421 for background risks varying between 1% and 0.4%, respectively. Conclusions: First-trimester uterine artery Doppler is a useful tool for predicting early-onset pre-eclampsia, as well as other adverse pregnancy outcomes. Based on the NNT, abnormal uterine artery Doppler in low-risk women achieves a sufficiently high performance to justify aspirin prophylaxis in those who test positive. [ABSTRACT FROM AUTHOR]

Abstract

Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is an opportunistic pathogen that colonizes the gastrointestinal and genitourinary tracts of up to 50% of healthy adults and newborns; it is responsible for significant morbidity and mortality. Early detection can be used to establish the use of antibiotic prophylaxis to significantly reduce neonatal sepsis. This article reviews methods of detection and prevention of GBS infection in the neonate. [ABSTRACT FROM AUTHOR]

Abstract

According to the Early External Cephalic Version (EECV2) Trial, planning external cephalic version (ECV) early in pregnancy results in fewer breech presentations at delivery compared with delayed external cephalic version. A Cochrane review conducted after the EECV2 Trial identified an increase in preterm birth associated with early ECV. We examined whether a policy of routine early ECV (i.e., before 37 weeks' gestation) is more or less costly than a policy of delayed ECV.
