Alcohol Consumption in HealthyOPRM1G Allele Carriers and Its Association with Impulsive Behavior
2015
AIMS: A link between alcohol use disorders (AUD) and impulsivity is well established. As there is evidence for the heritability of AUD, the investigation of the underlying genetic disposition for both conditions is an important issue. An association between AUD and a coding single nucleotide polymorphism (SNP) (rs1799971 encoding an Asn40Asp amino acid substitution, A118G) within the µ-opioid receptor 1 gene (OPRM1) has been reported. Therefore we tested the association between the OPRM1 A118G polymorphism and drinking as well as impulsive behavior in social drinkers. METHODS: A total of 214 healthy male social drinkers were recruited. Each participant was genotyped for the OPRM1 A118G vari…
Randomised controlled trial of lipiodol transarterial chemoembolisation with or without amiodarone for unresectable hepatocellular carcinoma.
2011
Abstract Background There is no consensus about the most effective method for transarterial chemoembolisation of hepatocellular carcinoma. Aim The aim of this phase II trial was to compare the efficacy and toxicity of lipiodol transarterial chemoembolisation with amiodarone in association with pirarubicin or doxorubicin versus lipiodol transarterial chemoembolisation with anthracycline alone in a control group. Methods Patients with unresectable hepatocellular carcinoma and Child-Pugh A/B7 were considered eligible for the trial. transarterial chemoembolisation was repeated every 6 weeks for a maximum of 4 sessions. Results Thirteen patients were randomised in the amiodarone group, and 14 we…
Resovist enhanced MR imaging of the liver: Does quantitative assessment help in focal lesion classification and characterization?
2009
Purpose: To improve characterization of focal liver lesions by a prospective quantitative analysis of percentage signal intensity change, in dynamic and late phases after slow (0.5 mL/s) Resovist administration. Materials and Methods: Seventy-three patients were submitted on clinical indication to MR examination with Resovist. Signal intensity of 92 detected focal lesions (5–80 mm) were measured with regions of interest and normalized to paravertebral muscle in arterial, portal, equilibrium and T1/T2 late phases, by two observers in conference. Five values of percentage variations per patient were obtained and statistically evaluated. Results: The enhancement obtained on dynamic study is mo…
Postoperative pain therapy after lumbar disc surgery.
2000
Object. This study was undertaken to determine whether a special postoperative pain administration of tramadol and diclofenac provides any benefits in patients who underwent microsurgical lumbar discectomy. Methods. The study consisted of 60 patients undergoing microsurgical lumbar discectomy. Patients were randomly divided into two groups based on the postoperative pain management: 1) Group A (n=30): no standardized pain therapy; these patients received on demand different analgesics and at variable dosages which were selected by the neurosurgeons; 2) Group B (n=30): standardized pain therapy with specific dosages of tramadol and diclofenac in regular time intervals during the first 48 ho…
Prospective, Single-Arm, Longitudinal Study of Biomarkers in Real-World Patients with Severe Asthma.
2019
ARIETTA was a prospective, single-arm, noninterventional, multicenter study in patients with severe asthma.To examine the predictive and prognostic abilities of type 2 biomarkers for severe asthma outcomes.Adult patients with severe asthma receiving daily inhaled corticosteroids (fluticasone propionate ≥500 μg or equivalent) and ≥1 second controller medication were enrolled. Biomarker, clinical, and safety data were collected over 52 weeks. The primary endpoint was the asthma exacerbation rate over 52 weeks in serum periostin-high (≥50 ng/mL at baseline) versus periostin-low subgroups (50 ng/mL). Correlations between biomarker levels (periostin, blood eosinophils, IgE, and fractional exhale…
Opioid receptor PET reveals the psychobiologic correlates of reward processing.
2008
Little is known about the neurobiologic correlates of human personality. On the basis of the key role of the central opioidergic system in addiction and substance abuse, we investigated the relationship between certain personality traits that are supposed to be relevant in addiction and the opioid receptor status in healthy subjects.We investigated 23 healthy male volunteers who were extensively clinically tested to exclude substance abuse. All of the subjects underwent 1 PET scan with the subtype-nonselective opioidergic radioligand 18F-fluoroethyl-diprenorphine under resting conditions without sensory or cognitive stimulation. Subsequently, the subjects were psychologically tested for the…
Influence of loperamide and loperamide oxide on the anal sphincter
1992
The objective of this study was to investigate the effects of the opioid loperamide and its recently synthesized pharmacologically inactive prodrug loperamide oxide on the anal sphincter. In a double-blind, placebo-controlled crossover study, anorectal manometry was performed in 12 healthy volunteers five hours after oral bolus application of 10 mg of loperamide, loperamide oxide, or placebo. Loperamide significantly increased the threshold volumes for minimal perception and urgency to defecate (P less than 0.05) and raised the volume required to abolish recovery of the rectoanal inhibitory reflex (P less than 0.05). These findings suggest that loperamide has a specific continence-improving…
Patient perspectives on methadone maintenance treatment in the Valencia Region: dose adjustment, participation in dosage regulation, and satisfaction…
2005
Desired adjustment of methadone dose, perceived participation in dosage regulation, and satisfaction with methadone treatment centres were assessed in a sample of opioid-dependent patients from the Valencia Region (eastern Spain). An independent interviewer asked 278 consecutively arriving patients to answer the survey, and 165 (59.4%) completed it. Adjustment of methadone dose was assessed with a -10 to +10 visual analogue scale (VAS-MD); participation in methadone dose regulation, with specific questions; and patient satisfaction, with the Verona Service Satisfaction Scale for methadone treatment (VSSS-MT). The methadone dose (mg/d) prescribed by physicians was (mean+/-S.D.) 68.0+/-30.4. …
Analgesic effects of nonsteroidal anti-inflammatory drugs in cancer pain due to somatic or visceral mechanisms.
1999
The role of nonsteroidal anti-inflammatory drugs (NSAIDs) is well established in the treatment of cancer pain. This class of drugs is considered particularly effective in pain due to somatic mechanisms, although proof of this observation is lacking. To ascertain whether NSAIDs are more effective in specific nociceptive forms of cancer pain, they were administered alone or added to opioids in 32 patients with a sole pain mechanism, somatic pain due to bone metastases (17 patients) or visceral pain (15 patients), respectively. Pain intensity, mean doses of opioids used, and symptoms were recorded after starting NSAID. A significant reduction in pain intensity was found at 3, 7, and 14 days. N…
Prevalence of opioid-related dysuria in patients with advanced cancer having pain.
2010
The aim of this study was to assess the prevalence of opioid-induced dysuria in patients with advanced cancer having pain and to evaluate the possible factors associated. A consecutive sample of cancer patients admitted to an acute pain relief and palliative care unit during 8 months was surveyed. Most patients (147, 86.5%) were receiving opioids at admission. The mean age was 65.1 (SD 12.2) and 106 patients were males. Twenty-five patients presented with dysuria at admission (of which 22 were taking opioids, 14.9%). Eleven patients were inserted a bladder catheter at admission for urine monitoring and 18 patients had urinary incontinence. During admission, 31 patients presented dysuria (19…
