Urinary N-terminal fragment of titin is a marker to diagnose muscular dystrophy in patients with cardiomyopathy

Publication date: September 2018Source: Clinica Chimica Acta, Volume 484Author(s): Akiomi Yoshihisa, Takatoyo Kiko, Takamasa Sato, Masayoshi Oikawa, Atsushi Kobayashi, Yasuchika TakeishiAbstractThe differential diagnosis of cardiomyopathy is important. It has been recently reported that urinary titin N (U-TN) is increased in patients with muscular dystrophy (MD), and is associated with muscular damage. We aimed to clarify whether U-TN is useful as a diagnostic tool for distinguishing MD from various cardiomyopathies [e.g. dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM)]. We measured and compared the U-TN/creatinine ratio (U-TN/Cr; pmol/mg/dl) in 278 control subjects and 331 patients with various cardiomyopathies (DCM, n = 199; sarcoidosis, n = 18; HCM, n = 86; amyloidosis, n = 15; Fabry disease, n = 6; MD, n = 7). The U-TN/Cr was significantly higher in MD patients than in patients with various cardiomyopathies and the control subjects (P

Focusing attention on biological markers of acute stressor intensity: empirical evidence and limitations. NEUROSCIENCE AND BIOBEHAVIORAL REVIEWS. The availability of biological markers that objectively quantify stress is a highly relevant issue.

Authors: Fontes MAP, Marzano LAS, Silva CC, Silva ACSE Abstract Despite the current availability of safe and efficient drugs for treating hypertension, a substantial number of patients are drug-resistant hypertensives. Aiming this condition, a relatively new approach named catheter-based renal denervation was developed. We have now a clinically relevant time window to review the efficacy of renal denervation for treating this form of hypertension. This short review addresses the physiological contribution of renal sympathetic nerves for blood pressure control and discusses the pros and cons of renal denervation pro...

In conclusion, ivabradine does not exhibit anti-arrhythmic properties in CPVT, which indicates that this blocker cannot be used as a plausible treatment for CPVT ventricular arrhythmias.

Conclusion: This is the first report of any pathogenic splice variant at first exon/intron boundary implicated in RPA and suggests another mechanism through which RDH5 variants could be associated with eye phenotype. This study also highlights the importance of a thorough phenotypic evaluation of heterozygous mutation carriers who may exhibit milder symptoms. PMID: 31933420 [PubMed - as supplied by publisher]

Abstract Sacral reflexes are important to allow the SCI practitioner to gain information about the state of the sacral spinal cord segments. The presence of the bulbocavernosus and/or the anal wink reflex indicate an intact spinal reflex arc and reflex conal autonomic function (as part of the upper motor neuron syndrome); their absence defines a lower motor neuron syndrome. The assessment of sacral reflexes helps predict the type of bladder, bowel and sexual functions and the related therapeutic interventions. We suggest adding the sacral component of the International Standards for the Assessment of Autonomic Fun...

Abstract The examination of sacral reflexes provides an important method to differentiate an upper motor neuron vs lower motor neuron spinal cord injury (SCI). Two common sacral mediated reflexes used as part of the neurological assessment include the bulbocavernosus reflex (BCR) and anal reflex. As the clinical information from these tests are similar, we suggest that the anal reflex provides a better first option as a non-invasive clinical assessment of sacral reflex status in clinical practice in SCI as the testing for the anal reflex is less intrusive and already being performed as part of the International St...
