The burden of oral disease is high in populations across the world. This is because of high consumption of free sugars. The WHO Guideline on Sugars Intake for Adults and Children recommended limiting free sugars to no more than 5% energy intake to protect oral health throughout the life-course. The objectives of this paper are to consider the implications of the Guideline for dental health practice and to advocate use of the common risk factor approach when providing dietary advice. As part of a broad range of actions needed to reduce free sugars intake, improved education for dental health professionals and supporting patients to eat less free sugars are key actions for the dental profession...

In neonates, a patent ductus arteriosus (DA) may be associated with severe complications. We used near-infrared spectroscopy (NIRS) with venous occlusion to investigate the influence of an open DA on peripheral muscle oxygenation/perfusion in preterm neonates. Approach: We analyzed secondary outcome parameters collected as part of prospective observational studies. NIRS measurements were performed between the first and third day of life. Arterial oxygen saturation (SaO2) and heart rate (HR) were monitored by pulse oximetry on the ipsilateral foot...

Obesity has reached epidemic proportions in many developed countries as Western dietary patterns have been widely adopted. These diets are characterized by excess energy intake as well as regular consumption of processed or "fast" foods and limited consumption of fruit, vegetables, and whole grains. The result is a high intake of saturated fat, refined carbohydrates, and sodium; and a low intake of fiber, vitamins, and other phytochemicals. This type of poor-quality diet has been associated with increased risk of chronic inflammatory diseases, including asthma...

The purpose of this research has been deciphering the Warburg paradox, the biochemical enigma unsolved since 1923. This paradox consists of the aerobic pyruvate conversion to lactate brought about by anaplastic cancer, through the metabolic pathway known as aerobic glycolysis. This pathway implies a heavy energetic waste. We solved the enigma by demonstrating that its specific character, i.e. the forced aerobic lactate exportation, represents a crucial metabolic device to counteract the cytotoxic effect produced by an excess of pyruvate at the connection of glycolysis with the Krebs cycle...

BACKGROUND: The contemporary Scottish diet is unhealthy and a risk factor for poor health outcomes including obesity. Over a third of Scottish children are at risk of being overweight or obese, and there have been calls to strengthen the evidence base on the role of the food retail environment around schools in influencing the consumption of unhealthy foods. METHODS: We examined the food retail environment around five secondary schools in Glasgow city, Scotland...

BACKGROUND: Accumulating evidence suggests that individual circulating saturated fatty acids (SFAs) are heterogeneous in their associations with cardio-metabolic diseases, but evidence about associations of SFAs with metabolic markers of different pathogenic pathways is limited. We aimed to examine the associations between plasma phospholipid SFAs and the metabolic markers of lipid, hepatic, glycaemic and inflammation pathways. METHODS: We measured nine individual plasma phospholipid SFAs and derived three SFA groups (odd-chain: C15:0 + C17:0, even-chain: C14:0 + C16:0 + C18:0, and very-long-chain: C20:0 + C22:0 + C23:0 + C24:0) in individuals from the subcohort of the European Prospective Investigation into Cancer and Nutrition (EPIC)-InterAct case-cohort study across eight European countries...

Background: Central venous oxygen saturation (ScvO2) reflects the balance of oxygen delivery and consumption. Low ScvO2 indicates the presence of inadequate oxygen delivery, while high ScvO2 indicates reduced oxygen consumption and is sometimes associated with a high mortality rate in critically ill patients from dysoxia. Thiamine is an essential cofactor in cellular aerobic metabolism. Thiamine deficiency is more prevalent than was previously thought, and underlies severe conditions in critically ill patients...

BACKGROUND AND OBJECTIVE: The increasing interest in the Mediterranean diet (MeDiet) hinges on the relevant role it plays in inflammatory diseases. Several clinical, epidemiological and experimental evidences suggest that consumption of the MeDiet reduces the incidence of certain pathologies related to oxidative stress, chronic inflammation and immune system diseases such as cancer, atherosclerosis and cardiovascular disease (CVD). DISCUSSION: These reductions can be partially attributed to extra virgin olive oil (EVOO) consumption which has been described as a key bioactive food because of its high nutritional quality and its particular composition of fatty acids, vitamins and polyphenols...

BACKGROUND: Decreases in mixed venous O2 saturation (SvO2) have been reported to occur in postcardiac surgery patients during weaning from mechanical ventilation. Our aim was to establish whether the physiological mechanism responsible for this phenomenon was a decrease in systemic O2 delivery (DO2) or an increase in global O2 consumption ([Formula: see text]O2). METHODS: We studied 21 mechanically ventilated, postoperative cardiac patients for 30 minutes before and 60 minutes after extubation...

Alcoholic liver disease (ALD), characterized by accumulation of fatty acids in liver cells, is usually caused by Chronic alcohol consumption. Our previous study has identified that DA protects against alcoholic liver injury in alcohol-fed rats through alleviating hepatocyte steatosis. It has emerged that saturated fatty acids could provoke endoplasmic reticulum (ER) stress and apoptosis in hepatocytes. This study was aimed to explore the impact of DA on ALD and further elaborate the underlying mechanisms. Results demonstrated that DA attenuates alcoholic liver injury in mice...

Aging may be related to oxidative damage accumulation and a low-grade inflammation, both responses are modulated by iron and phytochemicals. This study investigated the effect of tucum-do-cerrado (Bactris setosa Mart.) consumption on the expression of sirtuins (SIRT 1 and 3) and senescence marker protein-30 (SMP30), and on the redox and inflammatory responses, in adult rats supplemented or not with dietary iron. Male Wistar rats were treated for 12 weeks with: control diet (CT); iron enriched-diet (+Fe); control diet + 15% tucum-do-cerrado (Tuc); or iron enriched-diet + 15% tucum-do-cerrado (Tuc + Fe)...

The left ventricular (LV) working, crystalloid-perfused heart is used extensively to evaluate basic cardiac function, pathophysiology, and pharmacology. Crystalloid-perfused hearts may be limited by oxygen delivery, as adding oxygen carriers increases myoglobin oxygenation and improves myocardial function. However, whether decreased myoglobin oxygen saturation impacts oxidative phosphorylation (OxPhos) is unresolved since myoglobin has a much lower affinity for oxygen than cytochrome c oxidase (COX). In the present study, a laboratory-based synthesis of an affordable perfluorocarbon (PFC) emulsion was developed to increase perfusate oxygen-carrying capacity without impeding optical absorbance assessments...

Background: Factors limiting exercise in patients with COPD are complex. With evidence for accelerated pulmonary vascular aging, destruction of alveolar-capillary bed, and hypoxic pulmonary vasoconstriction, the ability to functionally expand surface area during exercise may become a primary limitation. Purpose: To quantify measures of alveolar-capillary recruitment during exercise and the relationship to exercise capacity in a cohort of COPD patients. Methods: Thirty-two subjects gave consent (53% male, with mean ± standard deviation age 66±9 years, smoking 35±29 pack-years, and Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification of 0-4: 2...

Moorland habitats dominated by the dwarf shrub Calluna vulgaris provide important ecosystem services. Drought is projected to intensify throughout their range, potentially leading to increased fire severity as moisture is a key control on severity. We studied the effect of low fuel moisture content (FMC) on fire severity by using 2×2m rain-out shelters prior to completing 19 experimental fires in two sites in Scotland (UK): a dry heath with thin organic soils and a raised bog with deep, saturated peat, both dominated by Calluna vulgaris...

Assessing the metabolic activity of a tissue, whether normal, damaged, aged, or pathologic, is useful for diagnosis and evaluating the effects of drugs. This report describes a handheld optical fiber probe that contacts the skin, applies pressure to blanch the superficial vascular plexus of the skin, then releases the pressure to allow refill of the plexus. The optical probe uses white light spectroscopy to record the time dynamics of blanching and refilling. The magnitude and dynamics of changes in blood content and hemoglobin oxygen saturation yield an estimate of the oxygen consumption rate (OCR) in units of attomoles per cell per second...

Background: Amygdalus scoparia kernel (ASK) oil is traditionally used for Hyperlipidemia. Compared to olive oil, it has higher proportion of unsaturated to saturated fatty acid besides exhibiting higher index of oxidative stability. The lipid-lowering effects of ASK oil however, has not been investigated yet. This study is the first one to evaluate such effects in patients with dyslipidemia. Results: Serum triglyceride levels significantly decreased in the intervention compared to control group (24...

INTRODUCTION: Inflammation plays a key role in the development of insulin resistance and atherosclerosis. Fatty acids and fiber intake can selectively alter gene expression by modifying inflammation. PURPOSE: We compared the postprandial expression of inflammatory genes after 2 distinct high-fat breakfast meals, before and after 1-month dietary interventions. METHODS: This crossover clinical trial included 18 individuals at low-to-moderate cardiometabolic risk participating in evaluations before and after two 4-week breakfast interventions-one rich in saturated fatty acids (SFA) and the other in unsaturated fatty acids (unSFA) and fiber...

INTRODUCTION: Nutritional therapy in heart failure (HF) patients has been focused on fluid and sodium restriction with the aim of decreasing volume overload. However, these recommendations are not well established and sometimes controversial. OBJECTIVE: To evaluate the effect of the consumption of a low-carbohydrate diet on oxygen saturation, body composition and clinical variables during two months of follow-up in chronic, stable heart failure patients. METHODS: In a parallel group randomized controlled clinical trial, 88 ambulatory patients were randomly assigned to a low-carbohydrate diet group (40% carbohydrates, 20% protein and 40% fats [12% saturated, 18% monounsaturated and 10% polyunsaturated]) or a standard diet group (50% carbohydrates, 20% protein and 30% fats [10% saturated, 10% monounsaturated and 10% polyunsaturated]) for two months...
