Breakfast cereals are often consumed with dairy products or non-dairy alternatives; however, the effect of the combination on blood glucose and food intake control is not well investigated. In a randomized, crossover study, 24 healthy women (age 22.7±2.5y; BMI22.1±1.5kg/m2) consumed, to satiation, one of three treatments Greek yogurt with granola (150kcal, 9.2g protein, 2.6g fat, 2.0g dietary fibre, and 21.5g available carbohydrate/100g); cultured coconut product with granola (146kcal, 3.2g protein, 3.2g fat, 5.6g dietary fibre, and 21.9g available carbohydrate/100g); or water control. The data were analyzed with RM-ANOVA. The 2h blood glucose iAUC was 52% lower after the dairy compared to non-dairy treatment (P less then 0.0001). While there were no differences in food intake between the caloric treatments consumed to satiation, protein intake was three times higher and fibre intake was four times lower after the dairy compared to non-dairy treatment. Both caloric treatments resulted in similar suppression of ad libitum food intake at 2h (P less then 0.003) and subjective appetite over 2h (P less then 0.0001) compared to water. The cumulative food intake over 2h was lower after water (P less then 0.05). The 1.8-fold-increase in postprandial insulin after dairy compared to non-dairy treatment may explain the reduction in blood glucose without an increase in subsequent energy intake. Novelty bullets • Blood glucose in young females is lower after a breakfast with granola in a high-protein cultured dairy than when in a high-fibre non-dairy cultured product. • Subjective appetite over 2h and food intake 2h later was similarly lower after both breakfasts but cumulative intake was higher compared to breakfast skipping.The purpose of this study was to determine potential adverse cardiac effects of chronic endurance training by comparing sympathovagal modulation via heart rate variability (HRV) and heart rate recovery (HRR) in middle-aged endurance athletes (EA) and physically-active individuals (PA) following maximal exercise. 36 (53±5 years) EA and 19 (56±5 years) PA were recruited to complete a two-week exercise diary and graded exercise to exhaustion. Time domain and power spectral HRV analyses were completed on recorded R-R intervals. EA had a greater HRR slope following exercise (95%CI, 0.0134-0.0138 vs. 0.0101-0.0104 beats/second;p less then 0.001). While EA had greater HRR 1-5 minutes post-exercise (all p less then 0.01), PA and EA did not differ when expressed as a percentage of baseline HR (130±19 vs. 139±19; p=0.2). Root mean square of successive differences in R-R intervals (rest and immediately post-exercise) were elevated in EA (p less then 0.05). Low frequency (LF) and high frequency (HF) spectral components were non-significantly elevated post-exercise (p=0.045-0.147) in EA while LF/HF was not different (p=0.529-0.986). This data suggests greater HRR in EA may arise in part due to a lower resting HR. While non-significant elevations in HF and LF in EA produces a LF/HF similar to PA, absolute spectral component modulation differed. These observations require further exploration. Novelty Bullets • Acute effects of exercise on HRV in EA compared to a relevant control group, PA, are unknown. • EA had greater HRR, and non-significant elevations in LF and HF compared to PA, yet LF/HF was not different. • Future work should explore the implications of this observation.Introduction Optical Coherence Tomography (OCT) is an intravascular imaging providing high-resolution images of morphological features of arterial wall. Nowadays, OCT is an accepted intravascular modality to study coronary arteries, stent implantation, and vessel injury. In the last decade, an increasing interest have been focused on the application of OCT in carotid arteries.Areas covered Literature evidence in the application of OCT in carotid arteries still remains debated. So far, OCT has been used as a research tool, aiming to evaluate atherosclerotic plaques' features and stents' behavior after implantation. This paper is intended to summarize clinical evidences and practices in the use of OCT in carotid arteries district and during CAS procedures. Literature review was completed via Pubmed search using Keywords.Expert opinion CAS is a safe and effective procedure when performed by trained physicians with a tailored approach. In this scenario, ambiguous pictures at ultrasound, angiography, and IVUS might be clarified using OCT.By providing unprecedented microstructural information on atherosclerotic plaques, OCT may identify the features of vulnerable carotid plaque and, by identifying possible defects after stent implantation as malapposition and plaque prolapse, it may help the tailoring approach to CAS.BACKGROUND Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is used as rescue for severe cardiopulmonary failure. We tested whether the ratio of CO2 elimination at the lung and the ECMO (VCO2ECMO/VCO2Lung) would reflect the ratio of respective blood flows and could be used to estimate changes in pulmonary blood flow (QLUNG), i. e. native cardiac output. METHODS Four healthy pigs were centrally cannulated for VA-ECMO. We measured blood flows with an ultrasonic flow probes. VCO2ECMO and VCO2Lung were calculated from sidestream capnographs under constant pulmonary ventilation during ECMO weaning with changing sweep gas and/or ECMO blood flow. If ventilation/perfusion (V/Q) ratio of ECMO was not one, the VCO2ECMO was normalized to V/Q=1 (VCO2ECMONORM). Changes in pulmonary blood flow were calculated using the relationship between changes in CO2 elimination and ECMO blood flow. RESULTS QECMO correlated strongly with VCO2ECMONORM (r2 0.95 - 0.99). QLUNG correlated well with VCO2LUNG (r2 0.65 - 0.89, p less then =0.002). Absolute QLung could not be calculated in a non-steady state. Calculated pulmonary blood flow changes had a bias of 76 (-266 to 418) ml/min and correlated with measured QLUNG (r2 0.974 - 1.000, p = 0.1 to 0.006) for cumulative ECMO flow reductions. https://www.selleckchem.com/products/Gefitinib.html CONCLUSIONS VCO2 of the lung correlated strongly with pulmonary blood flow. Our model could predict pulmonary blood flow changes within clinically acceptable margins of error. The prediction is made possible with a normalization to a V/Q of 1 for ECMO. This approach depends on measurements readily available and may allow immediate assessment of the cardiac output response.
