BACKGROUND Vitamin A supplementation (VAS) at birth has been associated with decreased mortality in Asia. Bacille Calmette-Guérin (BCG) vaccine is given at birth in tuberculosis-endemic countries. Previous studies suggest that VAS may influence the immune response to vaccines. OBJECTIVE Our objective was to examine whether VAS influences the immune response to simultaneously administered BCG ...

BACKGROUND Existing evidence for validity of the visual analog scale of the EQ-5D-3L questionnaire (EQ-VAS) is weak in Chinese-speaking respondents in Singapore. We therefore investigated the validity of the Chinese (Singapore) version of EQ-VAS in patients with diabetes. METHODS In a cross-sectional survey, patients with type 2 diabetes seen in a primary care facility completed an identical ...

Objective. To compare Visual Analogue Scale (VAS) scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved...

UNLABELLED The visual analog scale (VAS) has been used to assess the efficacy of pain management regimens in patients with acute postoperative pain, but its usefulness has not been confirmed in postoperative pain studies. We studied 60 subjects in the immediate postoperative period. The specific data collected were: VAS scores versus an 11-point numeric pain scale; repeatability in VAS scores o...

UNLABELLED The visual analog scale (VAS) is a tool widely used to measure pain, yet controversy surrounds whether the VAS score is ratio or ordinal data. We studied 52 postoperative patients and measured their pain intensity using the VAS. We then asked them to consider different amounts of pain (conceptually twice as much and then half as much) and asked them to repeat their VAS rating after e...

Vitamin A supplementation (VAS) programs targeted at children aged 6-59 months are implemented in many countries. By improving immune function, vitamin A (VA) reduces mortality associated with measles, diarrhea, and other illnesses. There is currently a debate regarding the relevance of VAS, but amidst the debate, researchers acknowledge that the majority of nationally-representative data on VA...

BACKGROUND Clinicians increasingly require short, efficient methods for assessing distress, both in applied research and clinical settings. Most of the available questionnaires are unsuitable for busy clinical settings. The visual analogue scale (VAS) is widely but empirically used to assess perceived stress. AIMS To provide evidence on two of the psychometric properties of the VAS: its discr...

Of 428 patients, mean age of 64.1+/-9.2 (30-84 years), undergoing an isolated CABG, pre- and one-year- postoperatively angina level and quality of life (QOL) were registered. QOL was registered following the EuroQol-registration, five domains and a visual analogue scale (VAS). Based on the VAS, the group was divided into Group A, 168 patients with a VAS < 60 and Group B, 260 patients with a VAS...

vas was too long to anastomose with the proximal end of the vas, or if the distal vas end retreated into the pelvis and was inaccessible at the inguinal area. This procedure is the same as previously reported. 3 If no sperm were found in the fluid from the proximal vas end, a secondary epididymal obstruction was considered, and the modified transverse intussusception vasoepididymostomy (VE), wh...

BACKGROUND Success in asthma management hinges on patients' competency to detect and respond to ever-changing symptom severity. Thus, it is crucial to have reliable, simple, and sustainable methods of symptom monitoring that can be readily incorporated into daily life. Although visual analogue scale (VAS) has been considered as a simple symptom assessment method, its utility as a daily symptom ...
