[The ECAD_O project: clinical caring epidemiology of pain in the hospital: the nurses' contribution]. / Il modello di sorveglianza ECAD_O-Epidemiologia Clinico-Assistenziale del Dolore in Ospedale: il contributo degli infermieri.

AIMS: ECAD_O is a project aimed to establish a surveillance of pain treatment--as part of routine care and as a hospital pharmacovigilance activity--with the following objectives: to assess in each participant ward prevalence of patients exposed to analgesics; to describe the pharmacological management schedules; to document the perception of health-care professionals on the effectiveness of treatment administered; to identify groups of patients whose pain is undertreated, through the activation of a collaborative protocol. METHODS: A multicentre (48 hospitals) and multidisciplinary (nurses, clinicians, pharmacists) cross-sectional survey was conducted in 6 index-days. Epidemiological, clinical and therapeutic data were collected and heath-care professionals (nurses or clinicians) were asked about their perception on the effectiveness of treatment administered and the reasons of non-effectiveness. RESULTS: In the 164 participant wards (61 surgery, 46 medicine, 28 oncology, 22 orthopaedics, 7 other) 3854 patients (20.9% of inpatients) were exposed to analgesics. The majority of patients (84.3%) received analgesics around-the-clock. Opioid analgesics were administered around-the-clock (64.7%; 2103/3250) as well as only as needed (27.1%; 164/604). According to health-care professionals, analgesic therapy administered was not effective in 516 patients (13.4% of sample). Inspite of this evaluation, 288 patients did not receive rescue therapy, because it was not prescribed (180 patients) or not administered even if prescribed (108 patients). CONCLUSIONS: The establishment of a surveillance scheme which could be adopted in the routine conditions of care to monitor the quality of pain control has been successfully tested on the basis of multidisciplinary teams where the nurse personnel plays a key role.

Pulse pressure and mortality from cerebrovascular diseases in type 2 diabetic patients: the Verona Diabetes Study.

BACKGROUND/OBJECTIVE: Previous studies conducted both in the general and diabetic population have shown that pulse pressure (PP) can predict mortality from cardiovascular diseases. The aim of the present study was to investigate the relationship between PP and specific cardiovascular mortality, i.e. from cerebrovascular and ischemic heart diseases, in a well-characterized cohort of type 2 diabetic patients. METHODS: A cohort of 1,128 known type 2 diabetic patients 56 to 74 years of age with at least 2 blood pressure measurements for each year between 1984-1986 was followed-up for ten years to assess specific causes of death. The analyses were carried out by using the mean and the coefficient of variation (CV) of PP. RESULTS: By the end of the 10-year follow-up period, 375 patients (178 male, 197 female) had died (33%). The mean PP resulted as an independent predictor of all causes and cardiovascular mortality. Remarkably, the mean PP, but not the CV of PP, was highly predictive of mortality from cerebrovascular diseases. The risk of cerebrovascular mortality rose by 86% with a 10 mm Hg increase in mean PP. PP turned out to be the most important predictor of cerebrovascular mortality among various pressure indexes (mean, systolic and diastolic pressure). CONCLUSION: The mean pulse pressure, but not the coefficient of variation is a strong predictor of cardiovascular mortality, mainly from cerebrovascular diseases, in type 2 diabetic patients.

Effects of moderate-intensity exercise training on plasma biomarkers of inflammation and endothelial dysfunction in older patients with type 2 diabetes.

BACKGROUND AND AIMS: Some plasma biomarkers of inflammation and endothelial dysfunction have been recently recognized as important cardiovascular risk factors. Currently, there is little information about the effects of aerobic exercise training on these biomarkers in older adults with type 2 diabetes. We have therefore assessed the effects of a twice-weekly moderate, aerobic exercise programme, without a concomitant weight loss diet, on plasma inflammatory and endothelial dysfunction biomarkers in older type 2 diabetic patients. METHODS AND RESULTS: A group of 16 sedentary, overweight, non-smoking, older patients with type 2 diabetes volunteered to participate in a 6-month, supervised, progressive, aerobic training study, two times per week. Plasma levels of hs-C-reactive protein (hs-CRP), soluble tumour necrosis factor (TNF)-alpha receptors, P-selectin and intercellular adhesion molecule-1 (ICAM-1) were measured before and after physical training. While hs-CRP and soluble TNF-alpha receptors remained essentially unaffected by physical training, plasma concentrations of P-selectin (P<0.001) and ICAM-1 (P<0.01) markedly decreased; physical training also increased HDL cholesterol by 12% (P<0.05) and decreased uric acid levels by approximately 33% (P=0.021). Body weight, waist circumference, blood pressure, haemoglobin A1c, plasma triglyceride and LDL cholesterol concentrations did not change. Interestingly, the exercise-induced changes in ICAM-1 and P-selectin levels remained significant after adjustment for the percent variations of body weight, waist circumference, haemoglobin A1c, HDL cholesterol and uric acid concentrations. CONCLUSIONS: A twice-weekly, 6-month, progressive aerobic-training programme, without a concomitant weight loss diet, is associated with significant decreases in circulating P-selectin and ICAM-1 levels and with a less atherogenic lipid profile in overweight, non-smoking, older type 2 diabetic individuals.

Relationship of nonalcoholic hepatic steatosis to overnight low-dose dexamethasone suppression test in obese individuals.

OBJECTIVES: To examine the association between nonalcoholic hepatic steatosis (HS) and the activity of the hypothalamo-pituitary-adrenal (HPA) axis, as evaluated by a low-dose dexamethasone suppression test, in obese subjects. DESIGN AND PATIENTS: In a cross-sectional study, we examined 54 obese, otherwise healthy, individuals with a negligible or zero daily alcohol consumption. MEASUREMENTS: HS (by ultrasonography), glucose tolerance status (by oral glucose load), insulin resistance [by homeostasis model assessment (HOMA)] and 1.0 mg postdexamethasone (postdex) suppression cortisol levels were measured. RESULTS: Subjects with nonalcoholic HS (n = 39) had markedly less suppressed circulating cortisol levels than those without HS (n = 15) (21.9 +/- 2.6 vs. 11.0 +/- 1.4 nmol/l, P < 0.001). In addition, subjects with nonalcoholic HS had significantly higher values of HOMA-insulin resistance score and circulating liver enzymes than their counterparts without HS. Age, body mass index (BMI), waist/hip ratio, plasma glucose concentration (both at fasting and after glucose load), lipids and blood pressure values did not differ significantly between the groups. Females were more represented among those without HS. The marked differences in postdex suppression cortisol levels that were observed between the groups were little affected by adjustment for sex, age, BMI, waist/hip ratio, HOMA-insulin resistance score, plasma lipids and liver enzyme levels. Similarly, in a logistic regression analysis, cortisol levels significantly predicted the presence of nonalcoholic HS (P = 0.032), independently of potential confounders. CONCLUSIONS: These results suggest that nonalcoholic hepatic steatosis is closely correlated with a subtle, chronic activation of the HPA axis in obese, otherwise healthy, individuals.
