Effects of dynamic exercise and metabolic control on left ventricular performance in insulin-dependent diabetes mellitus
1987
In subclinical diabetic cardiomyopathy, previous reports did not positively correlate the altered cardiac performance with metabolic parameters. Fifteen insulin-dependent diabetic subjects, without any clinical or instrumental evidence of heart diseases, were studied. Signs of diabetic microangiopathy were absent. Systolic time intervals, metabolic and hormonal parameters (blood glucose, free fatty acids, blood lactate and plasma norepinephrine) were evaluated at rest and after dynamic exercise during poor (MAGE 6.36 +/- 0.72 mmol/l) and good (MAGE 3.46 +/- 0.66 mmol/l) metabolic control, obtained by means of insulin therapy. Rest values of systolic time intervals were normal during poor an…
Hemostatic Agents in Periapical Surgery: A Randomized Study of Gauze Impregnated in Epinephrine versus Aluminum Chloride
2016
Abstract Introduction Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. Methods A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in epinephrine (epinephrine group) and aluminum chloride (aluminum chloride group). The analysis of the hemorrhage control was judged before and after the application of the hemostatic agents by the surgeon, and 2 examiners independently recorded it as adequate (complete hemorrhage control) or in…
Postprandial thermogenesis and alimentary sensory stimulation in human subjects
1999
OBJECTIVE: To study the role of alimentary sensory stimulation on the thermic effect of food. SUBJECTS: Nine male healthy volunteers (age: 20-34y, body mass index (BMI): 17.4-25.3 kg/m 2 ). DESIGN AND MEASUREMENTS: Four experimental situations were investigated on different days. Subjects: 1) ate a four course meal containing 2582kJ (meal), 2) saw, smelt and tasted the same courses (alimentary sensory stimulation), 3) saw, smelt and tasted non-alimentary substances (non-alimentary sensory stimulation), 4) received directly into the stomach the previous meal (tube feeding). Energy expenditure (EE) was measured over a 20 min rest period, then for 110 min. RESULTS: The changes over midday rest…
Night-rest urinary catecholamine excretion in relation to aspects of free time, work and background data in a teacher group
1991
Free time, work and background data were related to night-rest catecholamine excretion rates in a teacher group (n = 137) during an autumn term. The explained interindividual variance increased slightly towards the end of the term. Adrenaline excretion was predicted better than noradrenaline, notedly by coffee consumption, amount of physical activity, and subjective stress feelings which explained 16% of the variance in adrenaline excretion during night rest. However, the results indicated that the differences in catecholamine excretion during night rest remained mostly unpredictable.
Plasma catecholamine responses and neural adaptation during short-term resistance training
2000
Low exercise-induced plasma adrenaline (A) responses have been reported in resistance-trained indi- viduals. In the study reported here, we investigated the interaction between strength gain and neural adaptation of the muscles, and the plasma A response in eight healthy men during a short-term resistance-training period. The subjects performed 5 resistance exercises (E1-E5), consisting of 6 sets of 12 bilateral leg exten- sions performed at a 50% load, and with 2 days rest in between. Average electromyographic (EMG) signal amplitude was recorded before and after the exercises, from the knee extensor muscles in isometric maximal voluntary contraction (MVC) as well as during the exercises (a…
High volume and low concentration of anaesthetic solution in the perivascular interscalene sheath determines quality of block and incidence of compli…
2006
Background and objective: In the perivascular sheath of the brachial plexus, the volume of anaesthetic solution determines the quality of anaesthetic cover. Fibrous septa may divide the perivascular space into compartments, leading to inadequate diffusion of the anaesthetic solution. The aim of our study was to obtain good anaesthesia and less complications using high volume of low concentration anaesthetic solution, overcoming the obstacle of the septa with a double approach to the scalene sheath. Methods: Sixty patients scheduled for shoulder capsuloplasty received both Winnie interscalene brachial plexus block and Pippa proximal cranial needle approach. The patients were randomly assigne…
Hormonal Responses to a Resistance Exercise Performed Under the Influence of Delayed Onset Muscle Soreness
2002
Hormonal responses to an unaccustomed knee-extension exercise (E1; 5 times 10 repetitions with 40% load of 1RM [1 repetition maximum] followed by 2 sets until exhaustion) were compared in 6 men with the corresponding responses to an identical exercise performed 2 days later under the influence of delayed onset muscle soreness (DOMS) (E2). Both exercises were performed with a variable-resistance machine causing exhaustion with significantly fewer repetitions than a normal constant-resistance knee-extension device does. The E1 induced DOMS as expected, but the 1RM, the total work done, and the repetition number and frequency were not different in the 2 exercises. In the 2 sets to failure, the…
Impact of the WHO depression guideline on patient care by psychiatrists: a randomized controlled trial.
2008
AbstractBackgroundScientific literature reviews aim to summarize the state of knowledge and published empirical evidence. In contrast, medical guidelines are intervention tools that aim to improve physician behaviour and patient outcome. They can have positive effects, but they can also have negative effects. Their effects must be tested by research.MethodsIn a randomized controlled trial, 103 psychiatrists in private practice were either provided with the WHO depression guideline only (information group), or provided with the WHO depression guideline and trained for one day in this guideline (intervention group), or left uninformed (control group). They then treated a total of 497 patients…
Non-fatal and fatal liver failure associated with valproic acid.
2012
Little is known about hepatotoxicity associated with valproic acid (VPA), a widely used substance in neuropsychiatry.All reported cases to the German Federal Institute for Drugs and Medical Devices between 1993 and 2009 of VPA-induced serious hepatic side effects were evaluated.A total of 132 cases of serious VPA-associated liver failure were identified. Approximately one third (34.8%) occurred under VPA monotherapy, while the majority was seen with VPA plus co-medication, most frequently antiepileptics (34.8%) and benzodiazepines (16.7%). A subgroup of 34 cases (25.8%) had a fatal outcome, the largest number reported to date. Of these, 32.4% were under VPA monotherapy and 67.6% under VPA p…
Norepinephrine transporter gene polymorphism is not associated with susceptibility to alcohol dependence
2002
Abnormalities in monoamine neurotransmission have been implicated in the pathogenesis of alcoholism, mood disorders and schizophrenia. Murine norepinephrine transporter gene (NET) has been mapped to a region on chromosome 8 where a quantitative trait locus for ethanol sensitivity. Therefore we tested whether norepinephrine transporter (NET) gene variants confer susceptibility to either alcohol dependence or severe alcohol withdrawal symptoms. There is a highly polymorphic silent G1287A mutation in the NET gene. In our study 157 alcoholics and 185 healthy unrelated matched control subjects were analyzed for a silent G1287A mutation. No significant differences in allele and genotype distribut…
