BACKGROUND: Electroconvulsive therapy (ECT) causes acute changes in cerebral perfusion and oxygenation. Near-infrared spectroscopy is a novel, noninvasive technique to assess cerebral oxygen saturation (cSO2). We hypothesized that cSO2 increases during ECT and more so with atropine premedication and decreases when systemic desaturation (peripheral oxygen saturation <90%) occurs during ECT. METHODS: We performed a secondary analysis of a randomized trial of patients undergoing ECT for psychiatric illness during a 6-month period...

BACKGROUND: Platypnea-orthodeoxia syndrome (POS) is an uncommon disorder characterized by dyspnea (=platypnea) and desaturation (=orthodeoxia) in upright position and improvement of symptoms and blood oxygenation in supine position. Clinical presentation is heterogeneous and often confuses the clinician. OBJECTIVES: The present case report illustrates a complicated presentation of the underlying syndrome. METHODS: Description of a POS case in a 73-year-old female with thorough workup and tailored treatment...

OBJECTIVE: This study looks to correlate telemetry data gathered on patients with Pierre Robin Sequence (PRS) with sleep study data. Strong correlation might allow obstructive sleep apnea (OSA) to be reasonably predicted without the need for sleep study. METHODS: Charts from forty-six infants with PRS who presented to our children's hospital between 2005 and 2015 and received a polysomnogram (PSG) prior to surgical intervention were retrospectively reviewed. Correlations and scatterplots were used to compare average daily oxygen nadir, overall oxygen nadir, and average number of daily desaturations from telemetry data with apnea-hypopnea index (AHI) and oxygen nadir on sleep study...

BACKGROUND: We describe body composition, lipid metabolism and Stearoyl-CoA desaturase-1 (SCD-1) indices in patients with classical homocystinuria (HCU). METHODS: Eleven treated HCU patients and 16 healthy controls were included. Body composition and bone mineral density were assessed by dual X-ray absorptiometry. Sulfur-containing amino acids (SAA) and their derivatives (total homocysteine, cysteine, methionine, S-adenosylmethionine, S-adenosylhomocysteine, and glutathione), lipids (free fatty acids, acylcarnitines, triglycerides and lipoproteins), glucose, insulin, leptin, adiponectin, and isoprostanes were measured in plasma...

SCOPE: Diets rich in tomato products are associated with a reduced risk of various chronic disease processes. The carotenoid lycopene is most intensely studied as the bioactive mediating health effects, yet tomatoes contain an array of phytochemicals. We conducted an untargeted metabolomics study on blood plasma to identify novel markers of tomato consumption absorbed from the diet and released into the bloodstream in mice. METHODS AND RESULTS: Male mice were fed a control AIN-93G diet or the same diet supplemented with 0...

We estimated the heritabilities (h 2) and genetic and phenotypic correlations among individual and groups of fatty acids, as well as their correlations with six important carcass and meat-quality traits in Korean Hanwoo cattle. Meat samples were collected from the longissimus dorsi muscles of 1000 Hanwoo steers that were 30-month-old (progeny of 85 proven Hanwoo bulls) to determine intramuscular fatty acid profiles. Phenotypic data on carcass weight (CWT), eye muscle area (EMA), back fat thickness (BFT), marbling score (MS), Warner-Bratzler shear force (WBSF) and intramuscular fat content (IMF) were also investigated using this half-sib population...

OBJECTIVES: Desaturation leading to hypoxemia may occur during rapid sequence intubation (RSI). Apneic oxygenation (AO) was developed to prevent the occurrence of oxygen desaturation during the apnea period. The purpose of this study was to determine if the application of AO increases the average lowest oxygen saturation during RSI when compared to usual care (UC) in the emergency setting. METHODS: A randomized controlled trial was conducted at an academic, urban, level 1 trauma center...

OBJECTIVES: The number of ventilated patients is further increasing which leads to an increasing number of patients with weaning failure. In Germany, the treatment of patients with invasive out-of-hospital becomes more and more common. The aim of the study was to observe the outcome, the frequency and character of emergencies of patients with invasive out-of-hospital ventilation. METHODS: We conducted a prospective study over 1 year. 59 invasively ventilated patients living either at home or at nursing homes specialized in ventilator medicine were included...

BACKGROUND: It has been suggested that oxygen desaturation may be paradoxically related to the absence of an abnormal respiratory rate (RR) during acoustic respiratory rate (RRa) monitoring in a postoperative setting. We retrospectively compared the incidence of desaruration in patients without an abnormal RR with that in patients with an abnormal RR using propensity scorer matching. We also explored the factors contributing to oxygen desaturation without an RR monitoring alert. METHODS: We used ≤ 8 h postoperative data of the first 935 patients...

The synthesis of unsaturated fatty acids in Mycobacterium smegmatis is poorly characterized. Bioinformatic analysis revealed four putative fatty acid desaturases in its genome, one of which, MSMEG_1886, is highly homologous to desA3, the only palmitoyl/stearoyl desaturase present in the Mycobacterium tuberculosis genome. A MSMEG_1886 deletion mutant was partially auxotrophic for oleic acid and viable at 37°C and 25°C, although with a long lag phase in liquid medium. Fatty acid analysis suggested that MSMEG_1886 is a palmitoyl/stearoyl desaturase, as the synthesis of palmitoleic acid was abrogated, while oleic acid contents dropped by half in the mutant...

The incidence of obesity is rising at an alarming rate. Despite its recognition as an urgent healthcare concern, obesity remains largely an unsolved medical problem. A comprehensive screen for functional dietary phytochemicals identified proanthocyanidins as putative targets to ameliorate obesity. A full-scale purification of oligomeric proanthocyanidins (OPCs) derived from grape seed extract, yielded pure OPC dimer, trimer, tetramer, and their gallates (pOPCs). Forward chemical screening conducted in Caenorhabditis elegans suggested that pOPCs reduced the activity of lipase in vitro and triglyceride storage capacity in vivo Proanthocyanidin trimer gallate in particular modified lipid desaturation in C...

One of the most important functions of cognitive control is action cascading: the ability to cope with multiple response options when confronted with various task goals. A recent study implicates a key role for dopamine (DA) in this process, suggesting higher D1 efficiency shifts the action cascading strategy toward a more serial processing mode, whereas higher D2 efficiency promotes a shift in the opposite direction by inducing a more parallel processing mode (Stock, Arning, Epplen, & Beste, 2014). Given that DA is found in high concentration in the retina and modulation of retinal DA release displays characteristics of D2-receptors (Peters, Schweibold, Przuntek, & Müller, 2000), color vision discrimination might serve as an index of D2 efficiency...

BACKGROUND: Atherosclerotic conditions have been demonstrated to be associated with sleep- disordered breathing (SDB). Peripheral arterial disease (PAD) represents severe atherosclerosis with a high mortality. In early stages of PAD a substantial prevalence of sleep apnoea has already been shown. Here, we sought to determine the frequency of undiagnosed sleep apnoea in a homogeneous group of advanced PAD patients undergoing percutaneous revascularization. METHODS: 59 consecutive patients (mean age: 71...

A 12-year-old adolescent girl with intractable pneumonia and desaturation was sent to our hospital. An immunocompromised state was highly suspected because of an oral thrush persisting for a year and pneumonia of unusual severity. Laboratory tests confirmed she had human immunodeficiency virus (HIV) infection and full-blown AIDS. She lived with her adopted parents and reported no history of sexual abuse, drug abuse, or blood transfusion. We contacted the Center of Disease Control and discovered that her mother had HIV and had passed away a few years ago, thus confirming that she was a case of vertically transmitted HIV patient who had only developed AIDS recently...

Fatty acid desaturases (FADs) catalyze the introduction of a double bond into acyl chains. Two FAD groups have been identified in plants: acyl-acyl carrier proteins (ACPs) and acyl-lipid or membrane-bound FAD. The former catalyze the conversion of 18:0 to 18:1 and to date have only been identified in plants. The latter are found in eukaryotes and bacteria and are responsible for multiple desaturations. In this study, we identified 82 desaturase gene and protein sequences from 10 grass species deposited in GenBank that were analyzed using bioinformatic approaches...
