RESUMO

Background: During early skin-to-skin contact (ESSC), alterations in peripheral oxygen saturation (SpO2) and heart rate (HR) have been frequently observed. Objectives: This study aimed to determine the incidence of cardiorespiratory events (CREs) during ESSC in healthy term newborns (HTNs) and estimate the association of maternal and neonatal prognostic factors with the risk of CREs. Methods: A pooled analysis of the cohort from a clinical trial involving healthy mother-child dyads during ESSC was performed. Pulse oximetry was employed to continuously monitor SpO2 and HR within 2 h after birth. The individual and combined prognostic relevance of the demographic and clinical characteristics of dyads for the occurrence of a CRE (SpO2 <91% or HR <111 or >180 bpm) was analyzed through logistic regression models. Results: Of the 254 children assessed, 169 [66.5%; 95% confidence interval (95% CI), 60.5-72.5%] had at least one CRE. The characteristics that increased the risk of CRE were maternal age ≥35 years (odds ratio, 2.21; 95% CI, 1.19-4.09), primiparity (1.96; 1.03-3.72), gestational body mass index (BMI) >25 kg/m2 (1.92; 1.05-3.53), and birth time between 09:00 p.m. and 08:59 a.m. (2.47; 1.02-5.97). Conclusion: CREs were more frequent in HTNs born during nighttime and in HTNs born to first-time mothers, mothers ≥35 years, and mothers with a gestational BMI >25 kg/m2. These predictor variables can be determined during childbirth. Identification of neonates at higher risk of developing CREs would allow for closer surveillance during ESSC.

RESUMO

INTRODUCTION: Early skin-to-skin contact (ESSC) is associated with rare, sudden, unexpected postnatal collapse episodes. Placing the newborn in ESSC closer to an upright position may reduce the risk of airway obstruction and improve respiratory mechanics. This study assessed whether a greater inclination of the mother's bed during ESSC would reduce the proportion of healthy term newborns (HTNs) who experienced episodes of pulse oximeter saturation (SpO2) <91%. METHODS: We conducted a multicenter randomized controlled trial comparing the effect of the mother's bed incline, 45° versus 15°, on desaturation in HTNs during ESSC. Before delivery on 1,271 dyads, randomization was conducted, and stringent criteria to select healthy mothers and term newborns were monitored until after birth. Preductal SpO2 was continuously monitored between 10 min and 2 h after birth. The primary outcome was the occurrence of at least one episode of SpO2 <91%. RESULTS: 254 (20%) mother-infant dyads were eligible for analysis (45°, n = 126; 15°, n = 128). Overall, 57% (95% confidence interval [CI]: 51%-63%) of newborns showed episodes of SpO2 <91%. The proportion of infants with SpO2 <91% episodes was 52% in 45° and 62% in 15° (relative risk: 0.80; 95% CI: 0.6-1.07). CONCLUSIONS: We did not show that a high mother bed inclination during ESSC led to significantly fewer HTNs who experienced episodes of SpO2 <91%. Desaturation episodes from 10 min to 2 h after birth occurred in more than half of HTNs.

RESUMO

BACKGROUND: Early mother-child skin-to-skin contact (SSC) in the first 2 h postpartum is highly beneficial for both mother and child. However, cases have been reported of newborns who have experienced apparently life-threatening events (ALTEs) or sudden death during this procedure. The causes of these events are unknown. Newborn's prone position could influence the onset of these events but there is very little evidence to support any recommendation. We hypothesize that newborns' breathing obstruction episodes increase as mothers lie more horizontally. The main objective of this study is to compare the occurrence of desaturation and bradycardia episodes as a function of mother's bed incline. The study is designed as a randomized, controlled, assessor blind, multicenter, superiority trial with two parallel groups and 1:1 allocation ratio. METHODS: The study participants will be full-term healthy mother-newborn dyads from ten hospitals in Spain. Participants will be randomly assigned to one of two study arms defined by mother's bed inclination (45° or 15°). The planned sample size is 5866. Centralized permuted blocks randomization and assessor blinding will be implemented. The newborns will be monitored remotely with pulse oximetry, from 10 min to 2 h after delivery. We established SO2 and heart rate (HR) limit alarms, as well as an action protocol in the event of alarm activation. The primary outcome is the number of healthy newborns who undergo episodes of SO2 ≤ 90%. Secondary outcomes are the mean SO2 level, the number of newborns who experience episodes of SO2 ≤ 85%, the time to SSC discontinuation due to abnormal SO2 or HR, and episodes of HR < 111 beats per minute (bpm) or > 180 bpm. Subgroups and pooled analysis will be performed to identify if breast-feeding and mother and child positions favor the occurrence of desaturation or bradycardia episodes. DISCUSSION: A simple intervention such as modifying mother's bed angle of inclination while in SSC with her child during the first 2 h postpartum could favor newborn's hemodynamic and respiratory stabilization and thus contribute to reducing the onset of ALTEs.

RESUMO

In this paper, we estimate the relative risk that drunk drivers pose on sober drivers, passengers and pedestrians, and quantify the external cost of drunk driving in Spain between 2004-2015. Eventually we arrive at the following conclusions. Firstly, we find the relative risk of drunk drivers causing a crash during the night to be between 2.7-3.9 times higher than that of sober drivers. Secondly, our results point to a decline in drunk driving offences alongside an increase in its punition, mainly after the implementation of the Penalty Points System for driving licenses in Spain on July 1st 2006. We estimate that drunk drivers should be fined by 1250€, in order to offset its external costs. Overall, our assessment indicates a downturn in the external costs of drunk driving over the last decade in Spain.

RESUMO

This paper explores the causes behind the downturn in road accidents in Spain across the last decade. Possible causes are grouped into three categories: Institutional factors (a Penalty Point System, PPS, dating from 2006), technological factors (active safety and passive safety of vehicles), and macroeconomic factors (the Great recession starting in 2008, and an increase in fuel prices during the spring of 2008). The PPS has been blessed by incumbent authorities as responsible for the decline of road fatalities in Spain. Using cointegration techniques, the GDP growth rate, the fuel price, the PPS, and technological items embedded in motor vehicles appear to be statistically significantly related with accidents. Importantly, PPS is found to be significant in reducing fatal accidents. However, PPS is not significant for non-fatal accidents. In view of these results, we conclude that road accidents in Spain are very sensitive to the business cycle, and that the PPS influenced the severity (fatality) rather than the quantity of accidents in Spain. Importantly, technological items help explain a sizable fraction in accidents downturn, their effects dating back from the end of the nineties.

RESUMO

INTRODUCTION: Inflammation is one of the main contributory factors to the etiopathogenesis of multiple sclerosis (MS). Dietary interventions with Lipia citriadora (lemon verbena) extracts have been proved to be effective in the prevention of inflammatory diseases. OBJECTIVES: The aim of this study is to evaluate the effect of lemon verbena supplementation in pro- and anti- inflammatory serum biomarkers of patients with different clinical subtypes of multiple sclerosis. METHODS: The effect of lemon verbena supplementation (10% w/w verbascoside) was evaluated in a randomized, double-blinded placebo-controlled study with 30 participants classified in relapsing-remitting (n=10), primary progressive (n=5) and secondary progressive (n=15) MS presentations. Serum cytokine and C reactive protein levels were assessed in intervention and control groups for each MS clinical subtype after 28 days of dietary supplementation. RESULTS: Serum levels of C reactive protein and 8 cytokines/ inflammatory (IFN-γ, IL-12, IL-23, IL-6, TNF-α, TGF-ß, IL-4 and IL-10) markers were studied. Secondary progressive MS- supplemented patients showed C reactive protein concentrations significantly lower compared to the placebo group (p.


Introducción: La inflamación es uno de los principales factores que contribuyen en la etiopatogénesis de la esclerosis múltiple (EM). Se ha demostrado que las intervenciones en la dieta con extractos de Lipia citriadora (hierbaluisa) son efectivas en la prevención de las enfermedades inflamatorias. Objectivos: El objetivo de este estudio es evaluar el efecto de la suplementación con extractos de hierbaluisa en los biomarcadores de inflamación en suero de pacientes con diferentes subtipos clínicos de esclerosis múltiple. Métodos: El efecto de la suplementación con hierbaluisa (10 % p/p verbascósido) se evaluó mediante un estudio aleatorizado de doble ciego controlado con grupo placebo, constituido por 30 participantes clasificados según la forma de presentación de EM en: remitentes-recaídas (n=10), primaria progresiva (n=5) y secundaria progresiva (n=15). Los niveles de citoquinas y proteína C reactiva en suero se valoraron en los grupos intervención y control de cada uno de los subtipos clínicos de EM después de 28 días de suplementación en la dieta. Resultados: Se estudiaron los niveles en suero de proteína C reactiva y de 8 citoquinas como biomarcadores de inflamación (IFN-, IL-12, IL-23, IL-6, TNF-, TGF-, IL-4 e IL-10). Los pacientes del grupo de intervención con EM secundaria progresiva presentaron concentraciones de proteína C reactiva significativamente más bajos comparados con el grupo placebo (p.
