Right ventricular metabolic adaptations to high-intensity interval and moderate-intensity continuous training in healthy middle-aged men
Despite the recent studies on structural and functional adaptations of the right ventricle (RV) to exercise training, adaptations of its metabolism remain unknown. We investigated the effects of short-term, high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on RV glucose and fat metabolism. Twenty-eight untrained, healthy 40–55 yr-old-men were randomized into HIIT (n = 14) and MICT (n = 14) groups. Subjects performed six supervised cycle ergometer training sessions within 2 wk (HIIT session: 4–6 x 30 s all-out cycling/4-min recovery; MICT session: 40–60 min at 60% pe...

Right ventricular metabolic adaptations to high-intensity interval and moderate-intensity continuous training in healthy middle-aged men.
CONCLUSIONS: Only two weeks of physical training in previously sedentary subjects induces changes in RV glucose metabolism, volumes, and ejection fraction, which precede exercise-induced hypertrophy of RV. PMID: 27448554 [PubMed - as supplied by publisher]

Assessment of myocardial metabolic flexibility and work efficiency in human type 2 diabetes using 16-18Ffluoro-4-thiapalmitate, a novel PET fatty acid tracer
Altered myocardial fuel selection likely underlies cardiac disease risk in diabetes, affecting oxygen demand and myocardial metabolic flexibility. We investigated myocardial fuel selection and metabolic flexibility in human type 2 diabetes mellitus (T2DM), using positron emission tomography to measure rates of myocardial fatty acid oxidation {16-[18F]fluoro-4-thia-palmitate (FTP)} and myocardial perfusion and total oxidation ([11C]acetate). Participants underwent paired studies under fasting conditions, comparing 3-h insulin + glucose euglycemic clamp conditions (120 mU·m–2·min–1) to 3-h saline in...

Visceral Fat Triggers Heart Disease
I tell my patients to avoid drinking soda not just because they make you fat. Each sip of soda affects your health. Soda puts you at risk for health problems like metabolic syndrome. This is a collection of symptoms that can lead to diabetes, heart disease and other chronic diseases, like cancer. Soft drinks are the beverage of choice for millions of Americans. The latest research now reveals that sodas are a major cause of visceral fat — the deadliest kind of fat you can have, inflaming your tissues, rotting your blood vessels and upsetting your body chemistry. In a minute I’m going to tell you about a great healthy ...

Reversing the effects of the new anti-clotting drugs
The oral anticoagulant warfarin (Coumadin) became available for prescription in 1954. This anti-clotting drug commanded national attention when President Dwight Eisenhower received the drug as part of his treatment following a heart attack. No other oral anticoagulant was successfully developed and marketed in the United States until 2010. Warfarin is a dangerous drug. Along with insulin, it is responsible for the most emergency hospitalizations due to adverse drug reactions. Whereas insulin causes low blood sugar, warfarin is notorious for the complication of major bleeding. Warfarin is plagued by hundreds of drug-drug an...

Severe paraneoplastic hypoglycemia secondary to a gastrointestinal stromal tumour masquerading as a stroke.
We report the case of a 70-year-old previously healthy female who presented acutely to the Accident and Emergency department with left-sided vasomotor symptoms including reduced muscle tone, weakness upon walking and slurred speech. Physical examination confirmed hemiparesis with VIIth nerve palsy and profound hepatomegaly. A random glucose was low at 1.7 mmol/l, which upon correction resolved her symptoms. In hindsight, the patient recalled having had similar episodes periodically over the past 3 months to which she did not give much attention. While hospitalized, she continued having episodes of symptomatic hypoglycaem...

Is type 2 diabetes related to leukoaraiosis? an updated review
A significantly increased interest has been dedicated to the study of the effects of diabetes mellitus (DM) on the brain. DM is associated with an increased risk of stroke and cognitive decline. In patients with DM, neuroimaging discloses with high‐frequency structural changes, such as cerebral atrophy, infarcts and white matter lesions, also called leukoaraiosis (LA), an expression of small vessel disease. A previous review showed a relation between DM and both cerebral atrophy and lacunar infarcts, while the question about the relation between DM and LA remained unanswered. In this review, we provide an update on data ...

Imaging of a Clinically Relevant Stroke Model: Glucose Hypermetabolism Revisited Basic Sciences
Conclusions— The increased uptake of [2-18F]-2-fluoro-2-deoxy-d-glucose in cerebral ischemia most likely reflects hypermetabolism of glucose meeting increased energy needs of ischemic and hypoperfused brain tissue, and it occurs under both anaerobic and aerobic conditions measured by local lactate production. Infarct-related systemic hyperglycemia could serve to facilitate glucose supply to the ischemic brain. Glycemic control by insulin treatment could negatively influence this mechanism.

Improved cardiac function and dietary fatty acid metabolism after modest weight loss in subjects with impaired glucose tolerance
Using a novel positron emission tomography (PET) method with oral administration of 14(R,S)-[18F]-fluoro-6-thia-heptadecanoic acid (18FTHA), we recently demonstrated that subjects with impaired glucose tolerance (IGT) display an impairment in cardiac function associated with increased myocardial uptake of dietary fatty acids. Here, we determined whether modest weight loss induced by lifestyle changes might improve these cardiac metabolic and functional abnormalities. Nine participants with IGT, enrolled in a one-year lifestyle intervention trial, were invited to undergo determination of organ-specific postprandial dietary ...

Spinal cord infarction in diabetic pregnancy: A case report
Abstract Spinal cord infarction (SCI) is uncommon as compared to cerebral stroke. Moreover, SCI during pregnancy is rare. Here, we report a case of SCI in diabetic pregnancy, properly diagnosed, promptly treated, and a good prognosis achieved. A 38‐year‐old, pregnant woman, para 1, with type 1 diabetes mellitus on insulin since 14 years of age, was admitted to our hospital for paresthesia and numbness in the lower left side of the body, with movement disturbances. On the basis of the temporal profile of the onset and the multiple resonance imaging scans, SCI was diagnosed. Steroid pulse therapy and low‐dose aspirin a...
