Biochemical profiling study in umbilical cord blood in mothers with metabolic disorders.

BACKGROUND: During pregnancy metabolic disorders that affect differently the fetus, are known. These could be early or late disorders. OBJECTIVES: To analyze different biochemical parameters in umbilical cord blood (UCB) of healthy and pathological newborns from mothers with metabolic disorders. MATERIALS AND METHODS: Samples from UCB (121) were analyzed of newborn from mothers with metabolic disorders who attended at Obstetrics Division. Patients were consecutive, prospective and transversally studied. Newborn were classified as healthy (n = 65) and pathological (n = 56). The maternal metabolic disorders were gestational or non-gestational diabetes, glucose intolerance, insulin resistance and/or obesity).The disorders of the pathological newborns were intrauterine growth restriction (IUGR) and/or fetal distress. Glucose (Glu), urea, creatinine, uric acid (UA), total bilirubin (TB), total proteins (TP), albumin (Alb), transaminases (ALT/AST), alkaline-phosphatase (ALP), gammaglutamyltranspeptidase (GGT), creatinkinasa (CK), lactatedehydrogenase, amylase (amy), pseudocholinesterase, iron, calcium, phosphorus, magnesium (Mg), sodium, potassium, chlorine, cholesterol (Chol), HDL-Chol, LDL-Chol, triglycerides (TG), high sensitivity C reactive protein (hsCRP) were determined by recommended methods. T-Student's and Mann Withney tests were applied, p < .05. RESULTS: Pathological neonates (n: 56) showed a significant decrease in maternal gestation weeks (GW) and in newborn weight (NW) with respect to healthy newborns (n: 65) from mothers with metabolic disorders (p < .0001). Pathological neonates from mothers with metabolic pathologies (n: 56) showed significant increases in Chol, TG, TB (p < .01), LDL-Chol, UA, Mg, hsCRP, ALP levels (p < .05) and significant decreases in TP, Alb (p < .0001) and Glu, ALT, CK, GGT, amy (p < .05) in UCB with respect to healthy newborns. CONCLUSIONS: In pathological newborn, the decrease in GW and NW would be related to IUGR that accompany these metabolic disorders. The increases observed of the analyzed parameters would be related to cellular destruction associated to maternal pathology and decreases of the parameters to IUGR with hepatic immaturity.

After a decade of work, Fundacion Carulla-aeioTU has shown capacity to effectively support children's development in low-income settings through their participation in quality programming. Furthermore, this case study also describes how the organization, having proven its capacity to provide high-quality services directly to children, decided to innovate and bring about different solutions to reach and support other stakeholders in the early childhood development ecosystem.

Caracterización clínico epidemiológica de lactantes con bronquiolitis aguda grave / Clinical epidemiological characterization of infants with severe acute bronchiolitis / Caracterização epidemiológica clínica de lactentes com bronquiolite aguda grave

RESUMEN La bronquiolitis se considera como el primer episodio agudo de sibilancias en el contexto de un cuadro respiratorio de origen viral que afecta a niños menores de 24 meses que se acompaña de dificultad respiratoria de diversos grados. Este trabajo tiene como objetivo caracterizar a los pacientes con bronquiolitis aguda grave en la unidad de cuidados intensivos del Hospital Pediátrico Provincial Hermanos Cordové durante el periodo enero del 2014 a diciembre del 2018. Para lograr el objetivo planteado se realizó un estudio retrospectivo observacional descriptivo transversal con fases analíticas. El universo estuvo constituido por 72 pacientes, recolectando la información a partir de las historias clínicas y registro de control hospitalario. Se procesó la información utilizándose medidas expresadas en números absolutos, desviación estándar, media aritmética, porcentajes y tasas. Se demostró que la edad de aparición de la bronquiolitis aguda grave se presenta en menores de 6 meses de edad, resultando la estadía predominante de más de 48 horas. Se relaciona directamente la enfermedad con factores de riesgo como la no lactancia materna exclusiva y la malnutrición proteico-energética, requiriendo estos pacientes, al ingreso, oxígeno suplementario y aspiración de secreciones como terapéutica fundamental. Se presentaron complicaciones frecuentes como la neumonía e insuficiencia respiratoria aguda. Podemos concluir diciendo que se necesitan políticas bien definidas y protocolos de actuación actualizados para el manejo integral del lactante con bronquiolitis aguda grave, evitando así la aparición de complicaciones que pudieran llevar a la muerte del paciente.

ABSTRACT Bronchiolitis is considered to be the first acute episode of wheezing in the context of a respiratory picture of viral origin that affects children younger than 24 months accompanied by respiratory distress of various degrees. This study aims to characterize patients with severe acute bronchiolitis in the intensive care unit of the Hermanos Cordové Provincial Pediatric Hospital during the period from January 2014 to December 2018. To achieve the stated objective, a retrospective observational descriptive cross-sectional study was conducted with analytical phases. The universe consisted of 72 patients, collecting the information from the medical records and the hospital control registry. The information was processed using measures expressed in absolute numbers, standard deviation, arithmetic mean, percentages and rates. It was demonstrated that the age of onset of severe acute bronchiolitis occurs in children under 6 months of age, resulting in the predominant stay of more than 48 hours. The disease is directly related to risk factors such as exclusive non-breastfeeding and protein-energy malnutrition, requiring these patients, upon admission, supplemental oxygen and secretion aspiration as fundamental therapy. Frequent complications such as pneumonia and acute respiratory failure occurred. We can conclude by saying that well-defined policies and updated action protocols are needed for the comprehensive management of the infant with severe acute bronchiolitis, thus avoiding the appearance of complications that could lead to the death of the patient.

RESUMO A bronquiolite é considerada o primeiro episódio agudo de sibilância no contexto de um quadro respiratório de origem viral que afeta crianças menores de 24 meses acompanhadas de dificuldade respiratória de vários graus. Este estudo tem como objetivo caracterizar pacientes com bronquiolite aguda grave na unidade de terapia intensiva do Hospital Pediátrico Provincial de Hermanos Cordové, no período de janeiro de 2014 a dezembro de 2018. Para atingir o objetivo declarado, foi realizado um estudo transversal observacional descritivo retrospectivo com fases analíticas. O universo foi constituído por 72 pacientes, coletando as informações dos prontuários e do registro de controle hospitalar. As informações foram processadas utilizando medidas expressas em números absolutos, desvio padrão, média aritmética, porcentagens e taxas. Foi demonstrado que a idade de início da bronquiolite aguda grave ocorre em crianças menores de 6 meses de idade, resultando em permanência predominante de mais de 48 horas. A doença está diretamente relacionada a fatores de risco, como a não amamentação exclusiva e a desnutrição energético-protéica, exigindo desses pacientes, na admissão, oxigênio suplementar e aspiração de secreção como terapia fundamental. Ocorreram complicações frequentes, como pneumonia e insuficiência respiratória aguda. Podemos concluir dizendo que são necessárias políticas bem definidas e protocolos de ação atualizados para o manejo abrangente da criança com bronquiolite aguda grave, evitando o aparecimento de complicações que podem levar à morte do paciente.

Fetal coenzyme Q10 deficiency in intrahepatic cholestasis of pregnancy.

AIM: Intrahepatic cholestasis of pregnancy (ICP) is considered a high-risk condition because it may have serious consequences for the fetus health. ICP is characterized by the accumulation of bile acids in maternal serum which contribute to an imbalance between the production of reactive oxygen species and the antioxidant defenses increasing the oxidative stress experienced by the fetus. Previously, it was reported a significant decrease in plasma coenzyme Q10 (CoQ10) in women with ICP. CoQ10 is a redox substance integrated in the mitochondrial respiratory chain and is recognized as a potent antioxidant playing an intrinsic role against oxidative damage. The objective of the present study was to investigate the levels of CoQ10 in umbilical cord blood during normal pregnancy and in those complicated with ICP, all of them compared to the maternal ones. METHODS: CoQ10 levels and bile acid levels in maternal and umbilical cord blood levels during normal pregnancies (n=23) and in those complicated with ICP (n=13), were investigated. RESULTS: A significant decrease in neonate CoQ10 levels corrected by cholesterol (0.105±0.010 vs. 0.069±0.011, P<0.05, normal pregnancy vs. ICP, respectively), together with an increase of total serum bile acids (2.10±0.02 vs. 7.60±2.30, P<0.05, normal pregnancy vs. ICP, respectively) was observed. CONCLUSIONS: A fetus from an ICP mother is exposed to a greater risk derived from oxidative damage. The recognition of CoQ10 deficiency is important since it could be the starting point for a new and safe intervention strategy which can establish CoQ10 as a promising candidate to prevent the risk of oxidative stress.

Análisis microbiológico del tracto genital materno y de la sangre del cordón umbilical en relación con el daño neonatal / Microbiological analysis of the maternal genital tract and umbilical cord blood and its association with neonatal damage

La etiología que conduce al daño neonatal es multifactorial, y los procesos infecciosos pueden estar implicados en él. El objetivo de este estudio fue identificar microorganismos del tracto genital materno asociados con el daño neonatal, a fin de prevenir futuras complicaciones perinatológicas. Se estudiaron 711 embarazadas que concurrieron entre enero de 2010 y julio 2013 al consultorio externo de Obstetricia del Hospital de Clínicas de la UBA para sus controles prenatales, y cuyos partos también tuvieron lugar en dicho nosocomio. En la sangre del cordón umbilical se investigó la presencia de Ureaplasma urealyticum y Mycoplasma hominis mediante el cultivo con sustratos metabólicos (Micofast-Biomerieux), y la de Trichomonas vaginalis por PCR, con primers específicos. El estudio microbiológico del contenido vaginal se efectuó en 288 de las embarazadas en la semana 35 a 37. Se empleó la metodología convencional, a la que se agregó el cultivo en tioglicolato modificado para T. vaginalis. Se investigó la presencia de estreptococos grupo B (EGB) en hisopado anorrectaly de introito vaginal, utilizando enriquecimiento en caldo selectivo y posterior siembra en medio cromogénico. Se utilizaron los test de χ² Yates y de Fisher para muestras independientes, considerándose significativo p < 0,05. La vaginosis bacteriana (VB) se relacionó significativamente con el daño neonatal (p = 0,02), al igual que la presencia de M. hominis (p = 0,03) y de T. vaginalis (p = 0,03) en la sangre del cordón umbilical. Las complicaciones predominantes fueron el parto pretérmino, la rotura prematura de membrana (RPM), el bajo peso y un valor de Apgar <7. No se asoció al daño neonatal la presencia de U. urealyticum (p = 0,35) en el cordón umbilical, ni la de Candidaspp. (p = 0,94) o EGB (p = 0,18) en el tracto genital de las madres. Dado que ciertas alteraciones en la microbiota del tracto genital materno se relacionaron con el dano neonatal, consideramos de fundamental importancia realizar el estudio microbiológico del contenido vaginal durante el embarazo, para prevenir posibles complicaciones maternas y perinatológicas.

The etiology leading to neonatal damage is multifactorial, being genital infections one of the causes. The objective of the study was to identify microorganisms of the maternal genital tract that are associated with neonatal damage, in order to prevent future perinatal complications. Seven hundred and eleven pregnant patients attended their prenatal control during the period January 2010-July 2013. Ureaplasma urealyticum and Mycoplasma hominis presence was investigated in umbilical cord blood by metabolic substrates (Micofast-Biomerieux) and that of T. vaginalis, by PCR using specific primers. The microbiological study of the vaginal contents of 288 pregnant patients at weeks 35 to 37 was performed by conventional methods, adding the modified thioglycolate culture for T. vaginalis. Group B streptococcus (GBS) was investigated in anorectal and vaginal introitus swabs, using selective broth enrichment and subsequent isolation in chromogenic medium. The χ² Yates test and Fisher's test were used for independent samples. A p value <0.05 was considered statistically significant. The pathogens significantly related to neonatal damage were M. hominis (p = 0.03), T. vaginalis (p = 0.03), and BV (p = 0.02). Main complications were preterm birth, premature rupture of membranes (PRM), low weight and Apgar score <7. U. urealyticum (p = 0.35), Candidaspp. (p = 0.94) and GBS (p = 0.18) were not related to neonatal damage. Since different microorganisms of the maternal genital tract were related to neonatal damage, it is very important to perform the microbiological study of vaginal contents during pregnancy to prevent possible maternal and perinatal complications.

Infections of the lower genital tract associated to maternal and perinatal complications frequently occur during pregnancy. The aim of this study was to evaluate vaginal dysfunction through the analysis of basic vaginal states (BVS) using the methodology of balance of the vaginal content (BAVACO) and to compare it with the microbiological study of candidiasis, trichomoniasis and bacterial vaginosis (BV). Pregnant patients (1238) were examined from 2010 to 2012. In asymptomatic (A) (n: 1046) and symptomatic pregnant women (S) (n: 192) BVS I was 59.5% and 26% of the patients, respectively. BVS II was observed in 19.7% of A and in 17.2% of S. BVS III was only detected in A in 0.4%. BVS IV was observed in 14.4% of A and in 38% of S. BVS V was detected in 6% of A and in 18.8% of S. Yeasts were associated to BVS I and II in 55.5% and 23.2% of A, respectively; and in 32.4% and 31% of S, respectively. Trichomonas were associated to BVS I in 50% of A, to IV in 44.4% of S and to V in 33.3% of S. BAVACO susceptibility to detect yeasts was 80.4% and 85.5% in A and S, respectively; 40% and 75% in A and S, respectively, to detect trichomonas and 100% in A and S to detect BV. BAVACO specificity was 100% for all pathogens in A and S. The study of BVS proved useful as a guide to evaluate vaginal dysfunction, regardless of symptomatology. Therefore, this study is recommended as prenatal control.

Durante el embarazo se producen frecuentemente infecciones del tracto genital inferior asociadas a complicaciones maternas y perinatológicas. El objetivo del trabajo fue evaluar la disfunción vaginal mediante el análisis de los estados vaginales básicos (EVB) por la metodología del balance del contenido vaginal (BACOVA) y compararlo con el estudio microbiológico convencional en el diagnóstico de candidiasis, tricomonosis y vaginosis bacteriana (VB). Entre 2010 y 2012 se estudiaron 1238 pacientes embarazadas; 1046 eran asintomáticas (A) y 192 sintomáticas (S). La prevalencia del EVB I fue del 59,5 % y 26 %, respectivamente. El EVB II se observó en 19,7 % de las mujeres A y en 17,2 % de las S. El EVB III se detectó solamente en las A, en 0,4 %. El EVB IV se observó en 14,4 % de las A y en 38 % de las S. El EVB V se detectó en 6 % de las A y en 18,8 % de las S. En las mujeres A, las levaduras se asociaron a los EVB I y II en el 55,5 % y 23,2 % de los casos, respectivamente; entre las S, alcanzaron el 32,4 % y 31 % de los casos, en igual orden. Las tricomonas se asociaron al EVB I en el 50 % de las A, al EVB IV en el 44,4 % de las S y al EVB V en el 33,3 % de las S. La sensibilidad del BACOVA para detectar levaduras fue 80,4 % en las A y 85,5 % en las S; para detectar tricomonas, del 40 % y 75 %, y para detectar VB, del 100 % en los dos grupos.

OBJECTIVES: To study the prevalence of high-grade cervical intraepithelial neoplasia (CIN 2-3) during pregnancy and compare the rates of persistence, progression and regression of CIN 2-3 by colposcopically guided biopsy during pregnancy with respect to the postpartum period. Also to assess biopsy results during pregnancy and postpartum in relation to histopathology after treatment of lesions. POPULATION: Pregnant women with a histological diagnosis of CIN 2-3 confirmed by colposcopically guided biopsy during pregnancy. METHODS: Between 1989 and 2008, 11 700 pregnant women had cytologic and simultaneous colposcopic examinations during pregnancy. A colposcopically guided biopsy was performed when colposcopically suspicious high-grade lesions were detected, regardless of cytological results. Women with a histopathological diagnosis of CIN 2-3 during pregnancy were re-evaluated by colposcopically guided biopsy and treated during the postpartum period. RESULTS: CIN 2-3 was diagnosed in 56 of 11 700 (0.48%) pregnant women by biopsy. Thirty women complying with the protocol were assessed postpartum by histopathological studies, of whom 70% exhibited persistence, 13.3% progression and 16.7% regression of CIN 2-3. Twenty-nine were diagnosed by conization and one by colposcopically guided biopsy during the postpartum period, which revealed invasive cervical carcinoma. CONCLUSIONS: Due to the high rates of CIN 2-3 persistence during the postpartum period, we suggest that all patients in whom CIN 2-3 was diagnosed during pregnancy are biopsied and treated if necessary during the postpartum period, with at least a two-year follow-up control to prevent lesion recurrence.

Vaginal inflammatory status in pregnant women with normal and pathogenic microbiota in lower genital tract.

Objective. To assess the vaginal inflammatory status (VIS) in pregnant women, whether symptomatic or asymptomatic, by leukocyte quantification in relation to the microbiota during each pregnancy trimester (T). Materials and Methods. A thousand two hundred and forty eight vaginal exudates from pregnant women were prospectively examined. All the patients underwent a clinical and colposcopic examination and a microbiological study of vaginal exudates. Leukocyte quantification was determined by May-Grunwald Giemsa staining as LNR per field (400X). Results. Statistically significant differences (SSD) in LNR were observed in the VIS of asymptomatic patients (AP) compared with that of symptomatic ones (SP) with normal microbiota: 10-15 for the 1st T, <10, 20 to 25 and >25 for the 2nd T and >25 for the 3rd; with candidiasis: <10 for the 1st T, <10, 15 to 20 and >25 for the 2nd T and <10 and >25 for the 3rd T. In women with trichomoniasis, SSD in the LNR were observed between SP with LNR ≥ 10 and AP with NLR < 10 in the three trimesters altogether. In women with BV, no SSD were observed in the LNR of any AP with respect to SP for the three T. Conclusion. The VIS is influenced by vaginal microbiota and depends on the state of pregnancy and also, on gestational age. The pronounced leukocyte increase in asymptomatic patients in the absence of lower genital tract infection during the third trimester of pregnancy should be highlighted.

Histomorphometry of umbilical cord blood vessels in preeclampsia.

The authors hypothesized that preeclampsia may change the phenotype of umbilical cord vessels. Segments of umbilical cords were obtained from 29 pregnant women (20 healthy and 9 with preeclampsia), which were histomorphometrically assessed. Birth weight was 2928 ± 613 g for the control group vs 1749 ± 656 g for the preeclampsia group (P<.0001). A significantly shorter gestational period was noted in the preeclampsia group: 35 weeks vs 39 weeks in the healthy group. Measurements of the outer layer area (116.4 ± 55 µm(2) vs 56.5±25 µm(2) ; P=.0038), the inner layer area (63.1 ± 16 µm(2) vs 28.6±8 µm(2) ; P<.0001), the lumen area (8.4 ± 1 µm(2) vs 3.4±2 µm(2) ; P=.0003), and the wall/lumen ratio (20.3 ± 9 vs 3.1 ± 0.6; P<.0001) of arteries were significantly larger in the preeclampsia umbilical cords. Concerning veins, the wall/lumen ratio was higher in the preeclampsia group. In this study, the umbilical cord in preeclampsia showed significant changes in the structure of umbilical arteries, with increases in wall areas and wall/lumen ratios.

Maternal and fetal outcomes of 72 pregnancies in Argentine patients with systemic lupus erythematosus (SLE).

The purpose of the following study was to analyze maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus (SLE) and the influence of SLE exacerbations on those pregnancies. Seventy-two pregnancies in 61 SLE patients treated between January 1986 and February 2004 in Hospital de Clínicas "José de San Martin" were reviewed retrospectively. Patient age was 28.1 +/- 6.2 years (mean+/-standard deviation [SD]). Mean SLE duration was 4.5 +/- 3.2 years (range 6 months-10 years). No patient acquired the disorder during gestation. Four (5.5%) patients had signs of active disease at the beginning of her pregnancy. Sixteen patients, accounting for 20 pregnancies, had a history of lupus nephritis. Nine patients met secondary antiphospholipid syndrome criteria and had 13 pregnancies. There were 14 exacerbations of the disease during pregnancy (19.4%), with most flares being mild. The most common obstetric complications were gestational hypertension in 15 pregnancies (20.8%) and preeclampsia in 8 pregnancies (11%). Forty-six percent of pregnancies ended in preterm deliveries. There were 62 live births (1 twin birth; 85%), 6 stillbirths (8%), and 5 spontaneous abortions (7%). Thirty-nine percent of newborns had low birth weight. Adequate pregnancy follow-up and delivery care by an interdisciplinary team in Argentine SLE patients with no pre-gestational preparation resulted in maternal and fetal outcomes similar to those seen in world reference centers.
