Most of the tropical areas have sanitation problems to contend with. The French system of vertical-flow treatment wetlands (FS-VFTW) fed with raw wastewater could be a good water and sludge management solution. The purpose-adapted tropical design can reduce area requirement to below 1 m2 /population equivalents (p.e.). The Taupinière FS-VFTW on Martinique Island was built according to this design, with one stage but with a saturated layer at the bottom of the filter and a simplified trickling filter (TF) added for further treatment to meet the high performances targeted...

BACKGROUND: Oxygen saturation monitoring for children receiving respiratory support is standard worldwide. No randomised clinical trials have compared peripheral oxygen saturation (SpO2 ) targets for critically ill children. The harm of interventions to raise SpO2 to > 94% may exceed their benefits. METHODS: We undertook an open, parallel-group randomised trial of children > 38 weeks completed gestation and < 16 years of age receiving invasive or non-invasive respiratory support and supplemental oxygen who were admitted urgently to one of three paediatric intensive care units...

The generation of acid mine drainage (AMD) remains a major environmental challenge for the mining industry. The reclamation of old mine sites with pre-oxidized tailings is particularly challenging because of indirect oxidation reactions which can limit the overall effectiveness of an oxygen barrier to prevent AMD. The goal of this project was to quantitatively compare the effectiveness of different cover systems to reclaim two pre-oxidized acid-generating tailings sites, located in Quebec (Canada). Following laboratory column tests, field measurements and observations, coupled hydrogeological and geochemical numerical simulations were conducted to evaluate the effect of various system characteristics...

Medium- and long-chain methyl ketones are fatty acid-derived compounds that can be used as biofuel blending agents, flavors and fragrances. However, their large-scale production from sustainable feedstocks is currently limited due to the lack of robust microbial biocatalysts. The oleaginous yeast Yarrowia lipolytica is a promising biorefinery platform strain for the production of methyl ketones from renewable lignocellulosic biomass due to its natively high flux towards fatty acid biosynthesis. In this study, we report the metabolic engineering of Y...

Ventilator-induced lung injury is well recognized, and appropriate arterial saturation target is unknown, so gentle modes of ventilation and minimizing oxidative stress have been well studied. Our objective was to analyze any association between the oxygen levels at blood sampling and plasma levels of the interleukins IL-6, IL-1 β , IL-10, and IL-8 and TNF- α in preterm newborns under mechanical ventilation (MV) in their first two days. Methods . Prospective cohort including neonates with severe respiratory distress...

BACKGROUND: Using cerebral oxygen venous saturation post-cardiac arrest (CA) is limited because of a small sample size and prior to establishment of target temperature management (TTM). We aimed to describe variations in jugular bulb oxygen saturation during intensive care in relation to neurological outcome at 6 months post- CA in cases where TTM 33°C was applied. METHOD: Prospective observational study in patients over 18 years, comatose immediately after resuscitation from CA...

There is much debate between neonatologists and paediatricians about appropriate oxygen saturation targets for babies with chronic neonatal lung disease (CNLD). Overnight oximetry is used to guide the fraction of inspired oxygen to use. We did this literature review to examine the current literature on the use of overnight oximetry in term infants, preterm infants and babies with CNLD (especially relevant to ex-preterm babies with CNLD going home on oxygen). We reviewed the literature from January 1990 to October 2017 by searching the following databases: Cochrane Central Register of Controlled Trials, The Joanna Briggs Institute, CINAHL, MEDLINE, Scopus, EMBASE, ProQuest and Science Direct...

BACKGROUND: Currently, there is no gold standard for monitored anaesthesia care during oocyte retrieval. OBJECTIVE: In our institution, the standard is a conscious sedation technique using a target-controlled infusion (TCI) of remifentanil, titrated to maintain a visual analogue pain score less than 30 mm. This protocol is well accepted by patients but is associated with frequent episodes of respiratory depression. The main objective of this study was to evaluate whether the addition of a continuous intravenous infusion of ketamine could reduce these episodes...

BACKGROUND: Initial resuscitation with air is well tolerated by most infants born at term. However, the optimal fractional inspired oxygen concentration (FiO2 - proportion of the breathed air that is oxygen) targeted to oxygen saturation (SpO2 - an estimate of the amount of oxygen in the blood) for infants born preterm is unclear. OBJECTIVES: To determine whether lower or higher initial oxygen concentrations, when titrated according to oxygen saturation targets during the resuscitation of preterm infants at birth, lead to improved short- and long-term mortality and morbidity...

Acute viral lower respiratory tract infection is frequently associated with hypoxemia and respiratory distress, sometimes progressing to hypercarbia and respiratory failure. In recent years, trials have assessed the effects of oxygen supplementation and respiratory support with high-flow oxygen therapy. An oxygen saturation target of 90% is as safe and clinically effective as 94% in infants with bronchiolitis. Trials of high-flow humidified oxygen have demonstrated safety, but as yet poorly demarcated an appropriate place for use within the clinical course of the disease...

INTRODUCTION: Brain tissue hypoxia may contribute to preventable secondary brain injury after cardiac arrest. We developed a porcine model of opioid overdose cardiac arrest and post-arrest care including invasive, multimodal neurological monitoring of regional brain physiology. We hypothesized brain tissue hypoxia is common with usual post-arrest care and can be prevented by modifying mean arterial pressure (MAP) and arterial oxygen concentration (PaO2 ). METHODS: We induced opioid overdose and cardiac arrest in sixteen swine, attempted resuscitation after 9 min of apnea, and randomized resuscitated animals to three alternating 6-h blocks of standard or titrated care...

We will investigate the incidence of postoperative pulmonary complications (PPCs) with the prophylactic use of a high-flow nasal cannula (HFNC) after pediatric cardiac surgery. Children < 48 months old with congenital heart disease for whom cardiac surgery is planned will be included. The HFNC procedure will be commenced just after extubation, at a flow rate of 2 L/kg/min with adequate oxygen concentration to achieve target oxygen saturation ≥ 94%. This study will reveal the prevalence of PPCs after pediatric cardiac surgery with the prophylactic use of HFNC...

BACKGROUND: For 70 years, there has been a search for the optimal oxygenation of premature infants. In spite of the lack of evidence, guidelines have successively reduced oxygenation targets during these years. OBJECTIVES: (1) To present a summary of previously published meta-analyses of 5 randomized studies (NeOProM) which tested a low (85-89%) versus a high (91-95%) oxygen saturation target the first weeks after birth on outcome of immature newborn infants. (2) To present international recommendations for oxygenation the first weeks after birth...

OBJECTIVES: The patient's body surface area serves as the traditional reference for the determination of systemic blood flow during cardiopulmonary bypass (CPB). New strategies refer to different algorithms of oxygen delivery. This study reports on the mixed venous oxygen saturation (Sv O2 ) as the target for systemic blood flow control. We hypothesise that an Sv O2 >75% (Sv O2 75) is associated with better preservation of renal function and improved short-term survival. METHODS: This retrospective, 10-year, observational study analysed 6945 consecutive cardiac surgical cases requiring CPB...

BACKGROUND: Focus on skin-to-skin contact (SSC) as a family-centered care intervention in Neonatal Intensive Special Care (NISC) Units continues to increase. Previously, SSC has been shown to improve neonatal physiological stability, support brain development, and promote bonding and attachment. Limited research exists investigating SSC duration and neonatal physiological responses. PURPOSE: This study examined the relationship between SSC duration and the neonate's oxygen saturation, heart rate (HR), respiratory rate (RR), and temperature...
