Erythrocyte Membrane Docosahexaenoic Acid (DHA) and Lipid Profile in Preterm Infants at Birth and Over the First Month of Life: A Comparative Study with Infants at Term

An observational comparative study was designed to assess the fatty acids profile in erythrocyte membrane phospholipids of 30 preterm neonates (<32 weeks gestation) at birth and after 1 month of life versus a convenience sample of 10 infants born at term. The panel of fatty acids included the families and components of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and n-6 and n-3 polyunsaturated fatty acids (PUFAs) as well as enzyme activity indexes and fatty acids ratios. At birth, the comparison of fatty acid families between preterm and term neonates showed a significantly higher content of SFAs and n-6 PUFAs, and a significantly lower content of MUFAs and n-3 PUFAs in the preterm group. After 30 days of life, significantly higher levels of n-6 PUFAs and significantly lower levels of n-3 PUFAs among preterm neonates persisted. At 30 days of birth, n-6 PUFA/n-3 PUFA and arachidonic acid (ARA) ARA/DHA remained significantly elevated, and DHA sufficiency index significantly decreased in the preterm group. The pattern of n-3 PUFA deficiency at birth and sustained for the first month of life would support the need of milk banking fortified with DHA and the use of DHA supplementation in breastfeeding mothers

Severe COVID-19 during pregnancy and the subsequent premature delivery

Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Part prematurCoronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Parto prematuroCoronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Premature deliveryCoronavirus disease 2019 (COVID-19), which is caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic in January 2020. Although most of the cases in pregnant women are mild, there are reports of increasing severe infection in pregnancy. Only a few case of SARS-CoV-2 infection in preterm neonates delivered by mothers with COVID-19 have been reported till date. The possibility of in utero transmission of SARS-CoV-2 is highly controversial.1,2 While SARS-CoV-2 has been detected in several neonates by reverse transcriptionpolymerase chain reaction (RT-PCR) of nasopharyngeal swabs collected in the early hours or days of life,3,4 the reliability of these swabs is under scrutiny, as there is a chance of contamination by coronavirus-infected maternal body fluids

¿Cómo evaluar la sepsis neonatal de inicio precoz? Estudio comparativo de tres estrategias de detección

Cribado neonatal; Sepsis neonatal de inicio precoz; HemocultivoNeonatal screening; Neonatal early-onset sepsis; Blood cultureCribratge neonatal; Sèpsia neonatal d'inici precoç; HemocultiuIntroduction Early-onset neonatal sepsis (EONS) can cause significant morbidity and mortality, especially if it is not detected early. Given the decrease in its incidence in the past few decades, it is important to find a balance between reducing the use of diagnostic tests and continuing to detect affected patients. We compared 3 detection strategies in patients with risk factors (RFs) for infection: laboratory screening (S1), the Neonatal Sepsis Risk Calculator (S2) and clinical observation (S3). Patients and methods Retrospective observational study in neonates born at 34 weeks of gestation or later and with RFs or symptoms compatible with EONS. We analysed outcomes in our unit with the use of laboratory screening (S1) and compared them with the other two strategies (S2 and S3) to contemplate whether to modify our protocol. Results The study included 754 patients, and the most frequent RFs were prolonged rupture of membranes (35.5%) and maternal colonization by Streptococcus agalactiae (38.5%). Strategies S2 and S3 would decrease the performance of laboratory tests (S1, 56.8% of patients; S2, 9.9%; S3, 22.4%; P < 0.01), hospital admissions (S1, 11%; S2, 6.9%; S3, 7.9%; P < 0.01) and the use of antibiotherapy (S1, 8.6%; S2, 6.7%; S3, 6.4%; P < 0.01). Sepsis was diagnosed in 13 patients, and it would have been detected with S2 and S3 except in 1 patient who had asymptomatic bacteriemia by Enterococcus faecalis. No patient with mild and self-limited symptoms in whom antibiotherapy was not started received a diagnosis of sepsis later on. Conclusion Close clinical observation seems to be a safe option and could reduce the use of diagnostic tests, hospital admission and unnecessary antibiotherapy. The watchful waiting approach in patients with mild and self-limiting symptoms in the first hours post birth does not appear to be associated with failure to identify sepsis.Introducción La sepsis neonatal de inicio precoz (SNIP) puede causar morbi-mortalidad importante, sobre todo si se retrasa su identificación. La disminución de su incidencia en las últimas décadas motiva que sea importante encontrar un equilibrio entre reducir las pruebas complementarias y seguir detectando los pacientes afectos. Comparamos 3 estrategias de detección en pacientes con factores de riesgo (FR): E1. Cribado analítico; E2. Calculadora de riesgo de sepsis neonatal; E3. Observación clínica. Pacientes y métodos Estudio observacional retrospectivo, en recién nacidos con edad gestacional ≥34 semanas y con FR o sintomatología compatible con SNIP. Se analizaron los resultados de nuestra unidad con cribado analítico (E1) y se comparó con las otras 2 estrategias (E2 y E3) para valorar modificar nuestro protocolo. Resultados Se incluyeron 754 pacientes cuyos FR más frecuentes fueron la rotura prologada de membranas (35,5%) y la colonización materna por S.agalactiae (38,5%). Las E2 y E3 disminuirían la realización de analíticas (E1 56,8% de los pacientes; E2 9,9%; E3 22,4%; P < 0,01), los ingresos hospitalarios (E1 11%; E2 6,9%; E3 7,9%; P < 0,01) y la administración de antibioterapia (E1 8,6%; E2 6,7%; E3 6,4%; P < 0,01). 13 pacientes se diagnosticaron de sepsis, las cuales se hubieran detectado con E2 y E3, salvo un paciente con bacteriemia asintomática por E. faecalis. Ningún paciente con clínica leve y autolimitada en que no se inició antibioterapia, se diagnosticó posteriormente de sepsis. Conclusiones La observación clínica estrecha parece una opción segura y podría disminuir la realización de pruebas complementarias, la tasa de hospitalización y el uso de antibioterapia innecesaria. Mantener una conducta expectante en pacientes con sintomatología leve y autolimitada en las primeras horas de vida parece no relacionarse con la no identificación de sepsis

Utilización de las cánulas nasales de alto flujo en las unidades neonatales españolas

Neonate; Respiratory therapy; SurveyNeonato; Terapia respiratoria; EncuestaNounat; Teràpia respiratòria; EnquestaIntroduction The use of high-flow cannula therapy (HFNC) in neonatal units has increased in recent years, but there are no consensus guidelines on its indications and application strategies. Our aim was to know the rate of use of HFNC, their indications and the management variability among Spanish neonatal units. Material and methods Twenty-five-question survey for medical and nursing staff. Level II and III units were contacted by phone and sent in Google forms between September 2016 and December 2018. Results Ninety-seven responses (63.9% medical, 36.1% nursing), from 69 neonatal units representing 15 autonomous communities (87% level of care III; 13% level II). All units except one have HFNC with a humidified and heated system. Their most frequent indications are: non-invasive ventilation weaning (79.4%), bronchiolitis (69.1%), respiratory distress of the term newborn (58.8%), after extubation (50.5%). Minimum flow (1–5 L/min) and maximum flow (5–15 L/min) are variable between units. 22.7% have experienced some adverse effect from its use (9 air leak, 12 nasal trauma). Less than half have an employment protocol, but all the answers agree on the usefulness of national recommendations. Conclusions HFNC therapy is widely used in Spanish units, but there is great variability in its indications and strategies of use. National recommendations would be applicable in most units and would allow unifying its use.Introducción El uso de la terapia con cánulas de alto flujo (CNAF) en las unidades neonatales ha experimentado un incremento en los últimos años, pero no existen guías de consenso sobre sus indicaciones y estrategias de aplicación. Nuestro objetivo fue conocer la tasa de empleo de CNAF, sus indicaciones y la variabilidad de uso entre las unidades neonatales españolas. Material y métodos Encuesta de 25 preguntas dirigida a personal médico y de enfermería. Se contactó telefónicamente con unidades de nivel II y III y se envió en formato Google Forms entre septiembre 2016 y diciembre 2018. Resultados Se recibieron 97 respuestas (63,9% medicina, 36,1% enfermería), de 69 unidades neonatales que representan a 15 comunidades autónomas (87% nivel asistencial III; 13% nivel II). Todas las unidades, salvo una, disponen de CNAF con sistema humidificado y caliente. Sus indicaciones más frecuentes son: destete de ventilación no invasiva (VNI) (79,4%), bronquiolitis (69,1%), distrés respiratorio del recién nacido a término (RNT) (58,8%), tras extubación (50,5%). El flujo mínimo varía entre 1–5 lpm y el flujo máximo entre 5–15 lpm. El 22,7% ha experimentado algún efecto indeseado por su uso (9 fuga aérea, 12 traumatismo nasal). Menos de la mitad tiene protocolo de empleo, pero todas las respuestas coinciden en la utilidad de unas recomendaciones nacionales. Conclusiones La terapia con CNAF está ampliamente extendida en las unidades españolas, pero existe gran variabilidad en sus indicaciones y estrategias de utilización. Unas recomendaciones a nivel nacional serían aplicables en la mayoría de las unidades y permitirían unificar su empleo

This study proposes an alternative DDD design applicable for neonates. Methods Neonates (<1 month-old) from 6 Spanish hospitals during a 12-months period were included. Weight and weeks gestational age of each neonate were the variables collected. DDD (g) for each antimicrobial was calculated by multiplying the obtained weight times the recommended dose (mg/kg) of the antimicrobial for the most common infectious indication selected by the Delphi method. Results A total of 4820 neonates were included. Mean age was 36.72 weeks of gestational age and Mean weight was 2.687 kg. Standardized DDD (intravenous; oral route) for representative antimicrobials were: Amoxicillin (0.08; 0.08), amoxicillin-clavulanic acid (0.27; 0.08), ampicillin (0.27; x), cloxacillin (0.13; 0.13), penicillin G sodium (0.12), cefazolin (0.13), cefuroxime (0.27; x), cefotaxime (0.27), ceftazidime (0.27), ceftriaxone (0.13), cefepime (0.27) piperacillin-tazobactam (0.54), aztreonam (0.24), azithromycin (0.03; 0.03), clindamycin (0.04; 0.04), amikacin (0.04), gentamicin (0.01), metronidazole (0.04; 0.08), ciprofloxacin (0.04; 0.05), levofloxacin (x;x), fluconazole (0.02; 0.02), itraconazole (0.01; 0.01), fosfomycin (0.27). Restricted antimicrobials: meropenem (0.11), teicoplanin (0.02), vancomycin (0.08; 0.11), linezolid (0.08; 0.08), daptomycin (x), amphotericin B liposomal (0.01). Conclusions A useful method for antimicrobial DDD measurement in neonatology has been designed to monitor antimicrobial consumption in hospital settings. It should be validated in further studies and thereby included in the design for neonatal antimicrobial stewardship programs in the future.Antecedentes La dosis diaria definida de antimicrobianos (DDD), un método estandarizado para evaluar el consumo de antimicrobianos en la población adulta, tiene limitaciones que dificultan su uso en la población neonatal.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Erythrocyte Membrane Docosahexaenoic Acid (DHA) and Lipid Profile in Preterm Infants at Birth and Over the First Month of Life : A Comparative Study with Infants at Term

An observational comparative study was designed to assess the fatty acids profile in erythrocyte membrane phospholipids of 30 preterm neonates (<32 weeks gestation) at birth and after 1 month of life versus a convenience sample of 10 infants born at term. The panel of fatty acids included the families and components of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and n-6 and n-3 polyunsaturated fatty acids (PUFAs) as well as enzyme activity indexes and fatty acids ratios. At birth, the comparison of fatty acid families between preterm and term neonates showed a significantly higher content of SFAs and n-6 PUFAs, and a significantly lower content of MUFAs and n-3 PUFAs in the preterm group. After 30 days of life, significantly higher levels of n-6 PUFAs and significantly lower levels of n-3 PUFAs among preterm neonates persisted. At 30 days of birth, n-6 PUFA/n-3 PUFA and arachidonic acid (ARA) ARA/DHA remained significantly elevated, and DHA sufficiency index significantly decreased in the preterm group. The pattern of n-3 PUFA deficiency at birth and sustained for the first month of life would support the need of milk banking fortified with DHA and the use of DHA supplementation in breastfeeding mothers

Inadequate Content of Docosahexaenoic Acid (DHA) of Donor Human Milk for Feeding Preterm Infants : A Comparison with Mother's Own Milk at Different Stages of Lactation

A cross-sectional single-center study was designed to compare the fatty acids profile, particularly docosahexaenoic acid (DHA) levels, between milk banking samples of donor human milk and mother's own milk (MOM) for feeding preterm infants born before 32 weeks' gestation. MOM samples from 118 mothers included colostrum (1-7 days after delivery), transitional milk (9-14 days), and mature milk (15-28 days and ≥29 days). In the n-3 polyunsaturated fatty acids (PUFAs) group, the levels of α-linolenic acid (C18:3 n3) and DHA (C22:6 n3) showed opposite trends, whereas α-linolenic acid was higher in donor human milk as compared with MOM, with increasing levels as stages of lactation progressed, DHA levels were significantly lower in donor human milk than in MOM samples, which, in turn, showed decreasing levels along stages of lactation. DHA levels in donor human milk were 53% lower than in colostrum. Therefore, in preterm infants born before 32 weeks' gestation, the use of pasteurized donor human milk as exclusive feeding or combined with breastfeeding provides an inadequate supply of DHA. Nursing mothers should increase DHA intake through fish consumption or nutritional supplements with high-dose DHA while breastfeeding. Milk banking fortified with DHA would guarantee adequate DHA levels in donor human mil
