Quality of life and standard of living in a randomly selected group of psychiatrically disabled people in Sweden 2 years after a psychiatry reform.

In Sweden, a psychiatry reform, aimed at improving the living conditions of the psychiatrically disabled, came into force in 1995. The aim of the present study was to evaluate the impact of the reform by investigating quality of life and standard of living 2 years later in a randomly selected group of people with longstanding psychiatric disability. Self-ratings and interviews were conducted in a study group and a control group. The study group consisted of 19 women and 18 men (mean age 46.1 years) diagnosed with neurosis, schizophrenia or affective disorder. The control group consisted of 19 women and 17 men (mean age 48.7 years). Self-rated quality of life was significantly poorer in the study group (P < 0.0001, unpaired t-test), and so was housing (P < 0.001, test of similar proportions in independent samples). We found no significant positive correlation between subjective quality of life and standard of living in either group but a significant negative correlation in the control group (P < 0.05; r = 0.40, Pearson correlation coefficient). The results suggest that, in 1997, people with longstanding psychiatric disability still had poorer quality of life than the general population. This may be due to factors other than outward standard of living.     

Smoking and coffee intake following alcohol withdrawal in alcoholic inpatients

The aim of this study was to assess alcoholic inpatients' smoking and coffee intake variation following withdrawal. Only moderate smokers (less than 30 cigarettes/day) showed a significant increase of cigarette consumption after alcohol withdrawal. However, their urinary cotinine level did not vary, suggesting a behavioral, and not biological, compensation through smoking following alcohol withdrawal. Heavy smokers (30 cigarettes/day or more) showed no significant clinical or biological variation of smoking behavior. Coffee consumption increased after alcohol withdrawal in all patients, irrespective of smoking habits.     

Nicotine fading, behavioral contracting, and extended treatment: effects on smoking cessation

Twenty-eight subjects were randomly allocated to either a nicotine fading or a maintenance condition. The maintenance condition utilized behavioral contracting and extended treatment in addition to the nicotine fading to improve treatment outcome and avoid relapse. The maintenance condition achieved superior outcome on smoking measures at post-treatment and follow-up periods for self-reported smoking levels. Carbon monoxide levels were significantly lower for the maintenance condition at post-treatment, three month and six month follow-up. Saliva thiocyanate levels were significantly lower for the maintenance condition at the three month follow-up. Changes in health functioning indicated significantly lower diastolic and systolic blood pressure at six month follow-up for the maintenance condition. Additional research on nicotine regulation during nicotine fading and thiocyanate levels during experimental smoking would be useful. The use of behavioral contracting to enhance maintenance without therapeutic support warrants further research as well.     

Validation in the sheep of an ultrasound velocity dilution technique for haemodialysis graft flow

BACKGROUND: A simple, rapid, inexpensive method for measuring the flow in a patient's vascular access would permit routine monitoring during haemodialysis, and hence provide information of access graft deterioration sufficiently early to increase the success of minimally invasive remedial procedures. This paper reports the validation of such a method in animals. METHODS: A PTFE graft was implanted in sheep between the carotid artery and the jugular vein. While the sheep was under general anaesthesia and on an haemodialysis circuit, ultrasound velocity in its blood was perturbed by the injection of a 5-10 ml bolus of isotonic NaCl. The pump tubing flow was measured by a transit-time blood flow meter. This flow was combined with the areas of perturbation generated by the injection before and after mixing in the access flow to estimate graft flow. The calculated graft flow was compared to flow measured directly by a transit-time probe on the same carotid artery. RESULTS: Over a 10-fold range, 120-1260 ml/min, graft flow measured by ultrasound velocity dilution agreed well with graft flow measured directly with a scatter of 76 ml/min about the regression line. CONCLUSION: Ultrasound velocity dilution provides a method for measuring flow in the graft accurate enough for clinical evaluation of patients on dialysis.      

Fatal endocarditis due to Listeria monocytogenes

Three fatal cases of listerial endocarditis were studied. The first case occurred in an apparently healthy 58-year-old man, who presented with symptoms of pneumonitis. The second case developed in a 75-year-old woman with adenocarcinoma of the lung and aortic stenosis. In the third patient, an 83-year-old woman, aortic valve vegetations with perforations were found at necropsy. A colonic adenocarcinoma was found in the first and third cases. Ampicillin, alone or with an aminoglycoside, was the antibiotic used. Urgent valve replacement was performed in the first case. Listeria monocytogenes was isolated from blood cultures in all three cases. A review of 41 other patients with listerial endocarditis showed a nonspecific clinical picture, but septic complications occurred in one-half of the cases. Thirty-nine patients had at least one predisposing factor, which was underlying heart disease in 25 cases. The mortality rate was 48%.     

Do patient characteristics,disease, or treatment explain social inequality in survival from colorectal cancer?

This paper investigates the association between individually measured socioeconomic status (SES) and all-cause survival in colorectal cancer patients, and explores whether factors related to the patient, the disease, or the surgical treatment mediate the observed social gradient.     

Assessment of MRI criteria for abnormal brain MRI in acute monosymptomatic optic neuritis. Comparison to findings in healthy persons

To evaluate various MRI criteria we studied a representative group of 149 consecutive patients below 50 years with acute monosymptomatic optic neuritis (AMON), a frequent first manifestation of multiple sclerosis (MS). The presence, number, size, and localization of areas of increased signal (AIS) on T₂-weighted brain MRIs obtained at 1.5 T were described and compared with findings in 71 healthy persons aged 21–50 years without diabetes, cerebrovascular or neurologic diseases. MRI was performed within 2–145 days, median 16 days from onset of AMON and showed from 0 to 26 AIS, sized 2–30 mm, in 79 of 149 (53%) patients compared to 0–18 AIS, sized 2–12 mm, in 31 of 71 (44%) healthy persons. In patients, AIS were significantly more frequent in women than in men (χ² = 4.67, p > 0.05). Periventricular AIS were revealed in 70 (47%) patients and in 14 (20%) healthy persons. Subcortical AIS were present in 5 (3%) patients and in 18 (25%) healthy persons. Infratentorial AIS were present in only 3 (2%) patients. The sensitivity and specificity of previously proposed diagnostic MRI criteria for MS were unsatisfactory in our group of patients and have previously only been validated in definite MS. We therefore constructed and tested four new sets of criteria. The set with the best relation between sensitivity (e.g. 41%) and specificity (e.g. 93%) was the following: presence of two or more AIS, of which at least one is periventricular or infratentorial, combined with the absence of subcortical AIS. These criteria are recommended for patients with AMON and might be used in other patients with possible or probable MS.     

Combination of ABO blood group incompatibility and glucose-6-phosphate dehydrogenase deficiency: effect on hemolysis and neonatal hyperbilirubinemia

The incidence (%) of hyperbilirubinemia (serum bilirubin ≥257 μmol/l) was similar in neonates with a combination of ABO incompatibility and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency (45%), with ABO incompatibility (54%) or G-6-PD deficiency (37%), alone (ns). Carboxyhemoglobin values, corrected for inspired CO, were similarly elevated in all three groups (0.87 ± 0.32%, 0.82 ± 0.29%, 0.76 ± 0.18%, respectively, ns), but correlated with bilirubin only in those with ABO incompatibility alone. ABO-incompatible/G-6-PD-deficient neonates, compared with those with either condition alone, are not at increased risk for hemolysis or hyperbilirubinemia.
