At present, there are insufficient information about baroreflex sensitivity (BRS) and factors that determine BRS in premature newborns. The objective of this study was to determine the relationship between BRS and the characteristics that reflecting the intrauterine development (gestational age and birth weight), as well as postnatal development (postconception age and the actual weight of the child at the time of measurement). We examined 57 premature infants, who were divided into groups according to gestational age and postconception age as well as birth weight, and weight at the time of measurement...

Acute lung injury in the preterm newborns can originate from prematurity of the lung and insufficient synthesis of pulmonary surfactant. This situation is known as respiratory distress syndrome (RDS). In the term neonates, the respiratory insufficiency is related to a secondary inactivation of the pulmonary surfactant, for instance, by action of endotoxins in bacterial pneumonia or by effects of aspirated meconium. The use of experimental models of the mentioned situations provides new information on the pathophysiology of these disorders and offers unique possibility to test novel therapeutic approaches in the conditions which are very similar to the clinical syndromes...

Postoperative tracheal compression caused by hematoma is extremely rare in patients who have undergone cardiovascular operations. A 65-year-old man underwent elective redo aortic root replacement. Hemostasis was controlled with Surgicel packing (Ethicon, Somerville, NJ). After extubation, he had severe respiratory distress. The emergent computed tomographic scan showed severe obstruction of the tracheal bifurcation compressed by a hematoma around the packed Surgicel. During reexploration, a considerable hematoma was removed...

INTRODUCTION: Pediatric venous thromboembolism (VTE) is a rare but serious medical condition. Cystic fibrosis (CF) is a risk for recurrent pediatric VTE and has potential thrombophilic tendency. However, much remains unknown, including incidence and intrapopulation risk factors. METHODS: A retrospective cohort of pediatric CF patients followed at Children's Hospital Colorado from January 1st 2003 through May 20th 2016 was examined. Cases were identified by informatics and validated manually...

In July 2015, a municipal health department in Ohio received complaints of respiratory and ocular symptoms from patrons of an indoor waterpark resort. In response, the health department conducted an online survey in August 2015 through which 19 (68%) patron and employee respondents reported eye burning, nose irritation, difficulty breathing, and vomiting. On August 11, 2015, the health department requested a health hazard evaluation by CDC's National Institute for Occupational Safety and Health to characterize the prevalence of symptoms among employees and determine the etiology of work-related symptoms...

Autophagy is a highly conserved cellular mechanism in eukaryotes allowing the degradation of cell constituents. It is of crucial significance in both cellular homeostasis and nutrient recycling. During energy limited conditions plant cells can metabolize alternative respiratory substrates, such as amino acids, providing electrons to the mitochondrial metabolism via the tricarboxylic acid (TCA) cycle or electron transfer flavoprotein/ electron transfer flavoprotein ubiquinone oxidoreductase (ETF/ETFQO) system...

Nosocomial pneumonia (hospital-acquired pneumonia - HAP) is the form of pneumonia the symptoms of which present after more than 2 days (> 48 hours) of admission to hospital or as late as 14 days of discharge from hospital. The HAP pneumonias represent 13-18 % of all nosocomial infections. Incidence of HAP is the most frequent in mechanically ventilated patients. The type and representation of HAP agents primarily depends on the length of a patients stay in hospital and on their condition and character of treatment...

BACKGROUND: Children conceived by assisted reproductive technologies (ART) currently comprise 4% of Australian births. The manipulation of biological parameters related to fertilization and implantation are integral to successful ART but potentially pose a risk to the longer-term health of the offspring. There is consensus that many common adult health problems (particularly cardiovascular, metabolic and respiratory conditions) have their origins in early life, possibly before birth, and that risk trajectories track through childhood until clinical disease manifests in adulthood...

The dramatic transition to air breathing at birth represents a true challenge for the newborn infant mammal, a period in which neonatal respiratory diseases are common. Since the 1930s, fetal and newborn lambs have been the model of choice for whole-animal studies on neonatal respiration. The present review aims to illustrate the relevance of ovine models in studying the establishment of successful breathing at birth and its maintenance in the early postnatal period, as well as a number of abnormal conditions that can interfere with these processes...

Although a significant decrease has been reported in the incidence of diphteria in many regions of the world following the routine diphtheria immunization programs, the emergence of new cases indicated that toxigenic strains are still circulating in the community. Diphtheria vaccine does not provide protection against asymptomatic carriage and colonization of non-toxigenic Corynebacterium diphtheriae. It is a known fact that invasive infections may arise from non-toxigenic C.diphtheriae strains that the non-toxigenic strains can become toxigenic strains leading to diphteria...

INTRODUCTION: Sleep disorders are highly prevalent among the general population, although very few cases of sleep apnoea-hypopnoea syndrome (SAHS) have been reported in patients with narcolepsy. This study reviews the sleep disorders found in patients with narcolepsy, the prevalence of SAHS associated with these patients and their response to the different treatments. PATIENTS AND METHODS: We conducted an observation-based retrospective descriptive analysis of 25 patients diagnosed with narcolepsy, who were treated in our centre between October 2012 and December 2016...

Cerebral palsy (CP) refers to a spectrum of nonprogressive neurological disorders with disturbances in posture and movement, resulting from perinatal intrauterine insult to developing infant brain. Many conditions associated with CP require surgery. Such cases pose important gastrointestinal, respiratory, and other perioperative considerations. Anesthetic management in these cases is delicate. Intraoperative complications including hypovolemia, hypothermia, muscle spasms, seizures, and delayed recovery might complicate the anesthetic management...

Overflow metabolism in the presence of oxygen occurs at fast growth rates in a wide range of organisms including bacteria, yeast and cancer cells and plays an important role in biotechnology during production of proteins or metabolic compounds. As recently suggested, overflow metabolism can be understood in terms of proteome allocation, since fermentation has lower proteome cost for energy production than respiration. Here, we demonstrate that ArcA overexpression in aerobic conditions, results in downregulation of respiratory pathways and enhanced growth rates on glycolytic substrates of E...

Heparan sulfate (HS) is ubiquitously expressed on mammalian cells. It is a polysaccharide that binds growth factors, cytokines, and chemokines, and thereby controls several important physiological functions. Ironically, many human pathogens including viruses interact with it for adherence to host cells. HS functions can be regulated by selective modifications and/or selective cleavage of the sugar chains from the cell surface. In mammals, heparanase (HPSE) is the only known enzyme capable of regulating HS functions via a selective endoglycosidase activity that cleaves polymeric HS chains at internal sites...

Sensory gating is a preattentional mechanism to filter irrelevant information from the environment. It is typically reflected as a suppression of the event-related P50 component for successive sounds in the auditory modality. Although stress-induced sympathetic activation has been reported to disrupt P50 suppression, little is known about the modulatory effect of parasympathetic activation on early auditory sensory gating. We determined the parasympathetic effect on the magnetic P50 (P50m) suppression by controlling the respiratory rhythm and recording data simultaneously with magnetoencephalography and electrocardiography, using three successive click sounds as stimulus and ten normal individuals as study participants...

Background: Mitochondrial disorders can present as kidney disease in children and be difficult to diagnose. Measurement of mitochondrial function in kidney tissue may help diagnosis. This study was to assess the feasibility of obtaining renal samples and analysing them for respiratory chain enzyme activity. Methods: The subjects were children undergoing a routine diagnostic renal biopsy, in whom a clinical condition of renal inflammation, scarring and primary metabolic disorder was unlikely. A fresh sample of kidney was snap frozen and later assayed for the activities of respiratory chain enzyme complexes I, II/III, and IV using spectrophotometric enzyme assay, and expressed as a ratio of citrate synthase activity...

BACKGROUND: Drug effect evaluation is often based on subjective interpretation of a selection of patient data. Continuous analyses of high frequency patient monitor data are a valuable source to measure drug effects. However, these have not yet been fully explored in clinical care. We aim to evaluate the usefulness and applicability of high frequency physiological data for analyses of pharmacotherapy. METHODS: As a proof of principle, the effects of doxapram, a respiratory stimulant, on the oxygenation in preterm infants were studied...
