Rationale: Patients with cancer of the upper gastrointestinal tract or lung are more likely to present with malnutrition at diagnosis than, for instance, patients with melanoma. Low muscle mass is an indicator of malnutrition and can be determined by computed tomography (CT) analysis of the skeletal muscle index (SMI) at the 3rd lumbar vertebra (L3) level. However, CT images at L3 are not always available. At each vertebra level, we determined if type of cancer, i.e., head and neck cancer (HNC), oesophageal cancer (OC) or lung cancer (LC) vs. melanoma (ME) was associated with lower SMI. Methods: CT images from adult patients with HNC, OC, LC or ME were included and analyzed. Scans were performed in the patient’s initial staging after diagnosis. MIM software version 7.0.1 was used to contour the muscle areas for all vertebra levels. Skeletal muscle area was corrected for stature to calculate SMI (cm2/m2). We tested for the association of HNC, OC, or LC diagnosis vs ME with SMI by univariate and multivariate linear regression analyses. In the multivariate analyses, age (years), sex, and body mass index (BMI; kg/m2) were included. Betas (B;95%CI) were calculated and statistical significance was set at p
Het doel van deze studie was het testen van een dertigtal familieleden op Charcot-Marie-Tooth type 1A met behulp van een real time kwantitatieve polymerase kettingreactie. Duplicatie van het gen werd bij 50 % van de familieleden gevonden, overeenkomend met Mendeliaanse overerving.
Dit najaar zijn de langverwachte nieuwe consensuscriteria voor hetvaststellen van ondervoeding en sarcopenie gepresenteerd. Het gaatom de internationale criteria voor de diagnose van ondervoeding ende herziene Europese consensus over de sarcopenie-definitie en decriteria voor diagnose. Beide worden internationaal gedragen en zullen wereldwijd worden aanbevolen als de nieuwe standaard
