Conduction velocity study in type 1 diabetic patients.

1989

The role of metabolic abnormalities in the development of diabetic neuropathy is controversial. To investigate the peripheral nerve function and the influence of hyperglycemia on nerve conduction in insulin-dependent diabetes, a one-year neurophysiological study was carried out in 30 type 1 diabetic patients ranging in age from 2-16 years. During the 12-month follow-up period the glycosylated hemoglobin determination, motor conduction velocity of the peroneal nerve and the motor and sensory conduction of the tibial nerve were assessed 3 times, at the beginning of the study and every 6 months thereafter. The sensory latency was found significantly delayed in these patients as compared with t…

Effect of acetyl-l-carnitine in the treatment of diabetic peripheral neuropathy : A systematic review and meta-analysis

2017

Background/aim: Deficiency of acetyl-L-carnitine (ALC) and L-carnitine (LC) appears to play a role in peripheral diabetic neuropathy, although the evidence in humans is still limited. We conducted a systematic review and meta-analysis investigating the effect of ALC on pain and electromyographic parameters in people with diabetic neuropathy. Methods: A literature search in major databases, without language restriction, was undertaken. Eligible studies were randomized controlled trials (RCTs) or pre-and post-test studies. The effect of ALC supplementation on pain perception and electromyographic parameters in patients with diabetic neuropathy was compared vs. a control group (RCTs). The effe…

[Effect of flecainide on longitudinal and transverse conduction velocities in ventricular myocardium. An experimental study].

2007

It is known that the effect of flecainide on longitudinal and transverse ventricular conduction velocities depends on the coupling interval. If this is so, whether the longitudinal or transverse direction is predominantly affected could depend on the magnitude of the coupling interval. In order to investigate this hypothesis, we studied the effect of flecainide, 1 micromol/L, on conduction velocities in excised heart preparations from 11 rabbits using a basal cycle length of 250 ms and inserting two extrastimuli at a decreasing coupling interval. Flecainide significantly reduced both conduction velocities. However, the effect increased as the coupling interval decreased for only the longitu…

New loci associated with kidney function and chronic kidney disease

2010

Chronic kidney disease (CKD) is a significant public health problem, and recent genetic studies have identified common CKD susceptibility variants. The CKDGen consortium performed a meta-analysis of genome-wide association data in 67,093 individuals of European ancestry from 20 predominantly population-based studies in order to identify new susceptibility loci for reduced renal function as estimated by serum creatinine (eGFRcrea), serum cystatin c (eGFRcys) and CKD (eGFRcrea 60 ml/min/1.73 m 2; n = 5,807 individuals with CKD (cases)). Follow-up of the 23 new genome-wide-significant loci (P 5 × 10 8) in 22,982 replication samples identified 13 new loci affecting renal function and CKD (in or…

Motor planning of vertical arm movements in healthy older adults: does effort optimization persist with aging?

2019

AbstractSeveral sensorimotor modifications are known to occur with aging, possibly leading to adverse outcomes such as falls. Recently, some of those modifications have been proposed to emerge from motor planning deteriorations. Motor planning of vertical movements is thought to engage an internal model of gravity to anticipate its mechanical effects on the body-limbs and thus to genuinely produce movements that minimize muscle effort. This is supported, amongst other results, by direction-dependent kinematics where relative durations to peak accelerations and peak velocity are shorter for upward than for downward movements. The present study compares motor planning of fast and slow vertica…

In-vitro assessment of centrifugal pumps for ventricular assist.

1990

Currently two major types of centrifugal pumps are commercially available for ventricular assist: the Biomedicus-cone (Group I) and the Centrimed-impeller pump (now Sarns 3M) (Group II). To compare them for blood trauma and hemolysis, an in-vitro experiment was designed with a Stockert roller pump as a standard control (Group III). The in-vitro circuit was constructed consisting of a pump head, electromagnetic flow probe, polyvinyl chloride tubing and a reservoir, identical for all groups. Human ACD blood was used for priming and was circulated with a flow rate of 2 L/min for 24 h. Blood samples were taken at 0, 1, 3, 6, 12, and 24 h and zero control values were subtracted from the resultin…

Objective measures of nasal function

1995

Numerous techniques to objectively measure nasal function are available to the rhinologic surgeon. Rhinomanometry, acoustic rhinometry, laser Doppler flowmetry, saccharin transport time, determination of ciliary beat frequency, and olfactory and trigeminal event-related potentials are all techniques in current use. Rhinomanometry is the standard clinical tool used to indicate those patients complaining of nasal obstruction who are likely to benefit from septal and turbinate surgery. Acoustic rhinometry permits the precise localization of nasal stenoses and is the best predictor of a patient's postoperative satisfaction. It is, in addition, more sensitive than rhinomanometry in recording cha…
