Background: Vitiligo can negatively affect a patient's quality of life (QoL). A specific questionnaire has been developed and validated in the English language: the vitiligo-specific quality-of-life instrument (VitiQoL). The instrument was translated, culturally adapted and validated into Brazilian Portuguese (VitiQoL-PB). Objective: The aim of this study was to assess the QoL in adult patients through the VitiQoL and Dermatology Life Quality Index (DLQI) and in pediatric patients through the Children's Dermatology Life Quality Index (CDLQI) in a sample of patients with vitiligo. Methods: Subjects were selected from a dermatological outpatient clinic and from a private practice in Porto Alegre. The QoL of pediatric patients was evaluated using the CDLQI questionnaire. In adult patients we used the VitiQoL-PB and the DLQI. Results: A strong correlation between the scores of the total VitiQoL and DLQI was observed (r = 0.81; p < 0.001). The factor that most contributed to the final score of VitiQoL was stigma. In our sample, women had higher scores than men (p < 0.05). Psychiatric problems were associated with lower QoL. In the pediatric population, the median score of the CDLQI was 3 (interquartile range 1.3-7.3). There was a statistically significant correlation between the child's age and the CDLQI score (rs = 0.41, p = 0.044). Conclusion: This study confirms that the VitiQoL is easy to administer and adds important information about the impact of vitiligo on a South American population. Stigmatization is very present in the disease. There are groups of patients that are more vulnerable, like women, patients with psychiatric diseases and adolescents.
Hyperglycemia is a commonly encountered issue in critically ill patients in the intensive care setting. The presence of hyperglycemia is associated with increased morbidity and mortality, regardless of the reason for admission (e.g., acute myocardial infarction, status post-cardiovascular surgery, stroke, sepsis). However, the pathophysiology and, in particular, the treatment of hyperglycemia in the critically ill patient remain controversial. In clinical practice, several aspects must be taken into account in the management of these patients, including blood glucose targets, history of diabetes mellitus, the route of nutrition (enteral or parenteral), and available monitoring equipment, which substantially increases the workload of providers involved in the patients' care. This review describes the epidemiology, pathophysiology, management, and monitoring of hyperglycemia in the critically ill adult patient.
BACKGROUND:Vitiligo, although asymptomatic, highly compromises patients' quality of life (QoL). Therefore, an adequate evaluation of QoL is essential.OBJECTIVES:Translation, cultural adaptation and validation of VitiQol (Vitiligo-specific health-related quality of life instrument) into Brazilian Portuguese.METHODS:The study was conducted in two stages; the first stage was the translation and cultural/linguistic adaptation of the instrument; the second stage was the instrument's validation.RESULTS:The translated VitiQol showed high internal consistency (Cronbach alpha = 0.944) and high test-retest reliability and intraclass correlation coefficient=0.95 (CI 95% 0.86 - 0.98), p<0.001. There was no statistically significant difference between the means of the first completion of the VitiQoL questionnaire and the retest, p = 0.661. There was a significant correlation between VitiQoL and DLQI (r = 0.776, p <0.001) and also between VitiQoL-PB and subjects' assessment of the severity of their disease (r = 0.702, p <0.001).CONCLUSIONS:The impact of vitiligo on the QoL of Brazilian patients can be assessed by a specific questionnaire.
BackgroundObesity and diabetes mellitus are well-defined risk factors for cardiovascular mortality. The impact of antecedent hyperglycemia and body size on mortality in critical ill patients in intensive care units (ICUs) may vary across their range of values. Therefore, we prospectively analyzed the relationship between in-hospital mortality and preexisting hyperglycemia and body size in critically ill ICU patients to understand how mortality varied among normal, overweight, and obese patients and those with low, intermediate, and high glycated hemoglobin (HbA1c) levels.MethodsMedical history, weight, height, physiologic variables, and HbA1c were obtained during the first 24 h for patients who were consecutively admitted to the high complexity ICU of Hospital de Clínicas de Porto Alegre, Brazil, from April to August 2011. The relationships between mortality and obesity and antecedent hyperglycemia were prospectively analyzed by cubic spline analysis and a Cox proportional hazards model.ResultsThe study comprised 199 patients. The overall hospital mortality rate was 43.2% during a median 16 (8–28) days of follow-up. There was a progressive risk of in-hospital mortality with higher HbA1c levels, with the relationship becoming significant at HbA1c >9.3% compared with lower levels (hazard ratio 1.74; 95% confidence interval with Bonferroni correction 1.49–2.80). In contrast, mean body mass index (BMI) was higher in survivors than in nonsurvivors (27.2 kg/m2 ± 7.3 vs. 24.7 kg/m2 ± 5.0 P = 0.031, respectively). Cubic spline analysis showed that these relationships differed nonlinearly through the spectrum of BMI values. In a Cox proportional hazards model adjusted for Acute Physiology and Chronic Health Evaluation II score and HbA1c, the risk of in-hospital mortality progressively decreased with increasing BMI (BMI <20 vs. 20–23.9 kg/m2, P = 0.032; BMI <20 vs. 24–34.9 kg/m2, P = 0.010; BMI <20 vs. ≥35 kg/m2, P = 0.032).ConclusionsOur findings suggest that significant hyperglycemia prior to ICU admission is a risk factor for in-hospital mortality. Conversely, increasing BMI may confer an advantageous effect against mortality in critical illness independently of previous glycemic control.
