Attitude and knowledge of pain management among Italian nurses in hospital settings
2015
Pain is multidimensional, and, as such, the chief reason patients seek urgent healthcare services. If inadequately assessed and untreated, pain may negatively impact on the quality of life of the patient. Treating pain is an important step in regaining control over quality of life. The objective of the present study is to examine the level of knowledge and types of approach among Italian nurses who deal with pain assessment and management. The Ferrell and McCaffery's Knowledge and Attitudes Survey Regarding Pain (KASRP) was distributed to 286 nurses employed in one of the biggest specialized hospitals in Rome, Italy. The interviewed staff work at three different settings, according to the h…
Effects of Some Guanidino Compounds on Human Cerebral Arteries
1999
Background and Purpose —Accumulation of endogenous guanidino-substituted analogues of l -arginine in chronic renal failure might contribute to some of the vascular and neurological disorders of this pathology. We tested the hypothesis that in human cerebral arteries, some guanidino compounds may increase vascular tone, through nitric oxide (NO) synthase inhibition, and impair endothelium-dependent relaxation. Methods —Rings of human middle cerebral artery were obtained during autopsy of 26 patients who had died 3 to 12 hours before. The rings were suspended in organ baths for isometric recording of tension. We then studied the responses to N G -monomethyl- l -arginine (L-NMMA), N G , N G -…
The use of ketamine in a palliative-supportive care unit: a retrospective analysis.
2018
Background: To assess the response to ketamine in patients with difficult pain syndromes. Methods: The charts of patients with uncontrolled pain despite opioid dose escalation of at least two opioids or a combination of them, selected for a burst of ketamine and midazolam were reviewed. One hundred mg/day of ketamine and midazolam 15 mg/day by a continuous intravenous infusion for about 48 hours was offered to patients. Results: Forty-four patients received a burst of ketamine. Ten patients did not achieve any improvement. Pain intensity decreased from a mean of 7.8 (SD, 1.6) to 2.8 (SD, 1.3) (P<0.0005). The outcome was considered optimal, good, and mild in 24, 9, and 1 patients, respective…
Increased Risk of Rehospitalization for Acute Diabetes Complications and Suicide Attempts in Patients With Type 1 Diabetes and Comorbid Schizophrenia
2018
OBJECTIVE The aim of this large retrospective cohort study was to estimate the supplementary morbidity and mortality risks conferred by the co-occurrence of schizophrenia among young people with type 1 diabetes. RESEARCH DESIGN AND METHODS This nationwide population-based study included individuals aged 15–35 years hospitalized in France for type 1 diabetes from 2009 to 2012 with or without schizophrenia. For assessment of the occurrence of rehospitalization for acute diabetes complications, suicide attempts, and hospital mortality, multivariate logistic regressions and survival analysis adjusted for age, sex, and Charlson comorbidity index scores were performed. The association between ho…
Quantifying changes in EEG complexity induced by photic stimulation.
2009
Summary Objectives: This study aims to characterize EEG complexity, measured as the prediction error resulting from nonlinear prediction, in healthy humans during photic stimulation. Methods: EEGs were recorded from 15 subjects with eyes closed (EC) and eyes open (EO), during the baseline condition and during stroboscopic photic stimulation (PS) at 5, 10, and 15 Hz. The mean squared prediction error (MSPE) resulting from nearest neighbor local linear prediction was taken as complexity index. Complexity maps were generated interpolating the MSPE index over a schematic scalp representation. Results: Statistical analysis revealed that: i) EEG shows good predictability in all conditions and see…
Migraine mediates the influence of C677T MTHFR genotypes on ischemic stroke risk with a stroke-subtype effect.
2007
Background and Purpose— The objective was to investigate the role of C677T MTHFR polymorphism in migraine pathogenesis and in the migraine–ischemic stroke pathway. Methods— A first genotype–migraine association study was conducted on 100 patients with migraine with aura (MA), 106 with migraine without aura (MO), and 105 subjects without migraine, which provided evidence in favor of association of the TT677 MTHFR genotype with increased risk of MA compared with both control subjects (OR, 2.48; 95% CI, 1.11 to 5.58) and patients with MO (OR, 2.21; 95% CI, 1.01 to 4.82). Based on these findings, mediational models of the genotype–migraine–stroke pathway were fitted on a group of 106 patients …
Endothelium-independent contractions of human cerebral arteries in response to vasopressin.
1990
We studied the effects of vasopressin in isolated segments from branches (500-700 micrograms in external diameter) of human middle cerebral arteries obtained during autopsy of 15 patients who had died 3-8 hours before. Paired segments, one normal and the other de-endothelized by gentle rubbing, were mounted for isometric recording of tension in organ baths. In 11 normal segments, vasopressin produced concentration-dependent contractions with an EC50 of 7.0 X 10(-10) M. Removal of the endothelium from 12 segments did not significantly affect vasopressin-induced contractions. Vasopressin produced further contractions in arterial segments with (n = 4) or without (n = 5) endothelium precontract…
The Atrial Natriuretic Peptide Genetic Variant rs5068 Is Associated With a Favorable Cardiometabolic Phenotype in a Mediterranean Population
2013
OBJECTIVE We hypothesized that the minor allele of the atrial natriuretic peptide (ANP) genetic variant rs5068 is associated with a favorable cardiometabolic phenotype in a general Mediterranean population. RESEARCH DESIGN AND METHODS We genotyped a random sample of the residents of Ventimiglia di Sicilia, Sicily, for rs5068. RESULTS Genotype frequencies of rs5068 are AA, 93.5%; AG, 6.4%; and GG, 0.1%. All subsequent analyses are AA versus AG+GG. After adjusting for age and sex, the minor G allele is associated with lower BMI (estimate [SE]: −1.7 kg/m2 [0.8], P = 0.04). In the AG+GG group, males with HDL cholesterol levels &lt;40 mg/dL are less frequent (P = 0.05) and obesity tends to …
Relationships between 24 h blood pressure load and target organ damage in patients with mild-to-moderate essential hypertension.
2001
Objective: To analyse the relationships between 24 h blood pressure load (the percentage of systolic/diastolic blood pressures exceeding 140/90 mmHg while awake and 120/80 mmHg during sleep) and some indices of hypertensive target organ involvement, independently of the mean level of 24 h blood pressure. Methods: One hundred and thirty patients with mild-to-moderate hypertension underwent 24 h ambulatory blood pressure monitoring, ocular fundus examination, microalbuminuria assay and two-dimensional guided M-mode echocardiography. The study population was divided into subsets according to the systolic and diastolic 24 h blood pressure load values predicted from the regression equation relat…
Polymorphism insertion/deletion of the ACE gene and ambulatory blood pressure circadian variability in essential hypertension
2001
OBJECTIVE The objective of the present study was to analyze the influence of the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme on ambulatory blood pressure values and circadian variability in untreated patients with hypertension. MATERIAL AND METHODS Ninety-nine essential hypertensive patients, less than 50 years old (mean age 39.5+/-7.0 years), previously untreated with antihypertensive drugs were included. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed with a Spacelabs (90202 and 90207) monitor, during a regular working day in unrestricted ambulatory conditions. The I/D polymorphism of the ACE was determined by PCR. RESULTS The dist…
