    Notizen: Abstract Fluid overload worsens respiratory failure; conversely, fluid restriction has been associated with a higher survival rate without chronic lung disease. We therefore hypothesised that fluid restriction in the perinatal period might improve lung function in ventilated, prematurely born infants of very low birthweight. As a consequence, we compared in a randomised trial the effect of two fluid regimes on perinatal lung function. On one regime infants were to receive 60 ml/kg on day 1, increasing to 150 ml/kg by day 7, and on the other regime approximately 25% less fluid was to be prescribed. Lung function was assessed by measurement of functional residual capacity (FRC) and compliance. Measurements were made daily on days 1 to 5 and then on day 7. Ninety infants, median gestational age 28 weeks (range 23–33), were included in the study. There were no significant differences between the two groups regarding their gestational age or birthweight, or in the proportions who received antenatal steroids or postnatal surfactant. The infants on the restricted regime received significantly less fluid (P 〈 0.01). The only significant differences in lung function between the two groups, however, were that the infants on the restricted regime had a higher mean compliance on day 3, but thereafter the difference was reversed. Colloid intake, however, unfavourably affected lung function, total colloid intake being negatively correlated with both the area under the curve of birth-adjusted FRC (P=0.003) and compliance (P=0.001). Conclusion We conclude that early fluid restriction appears to have very little impact on perinatal lung function.

    Notizen: Abstract Neonatal chronic lung disease (CLD) is usually diagnosed if an infant remains oxygen dependent beyond 36 weeks postconceptional age (PCA). Our aim was to determine whether a shorter duration of respiratory support accurately predicted subsequent respiratory morbidity. A total of 103 infants, median gestational age 29 weeks (range 23–35), were followed prospectively for 5 years. They had a birth weight of 〈1500 g or, if a birth weight of between 1500 and 2000 g, had required neonatal ventilatory support. Parents completed diary cards; their child had positive symptom status if, in any one year, they coughed and/or wheezed on at least 3 days per week for a 4-week period or for at least 3 days following each upper respiratory tract infection. Subsequent respiratory morbidity, positive symptom status in years 1 and 2 or all 5 pre-school years, was related to various definitions of prolonged respiratory support: intermittent positive pressure ventilation dependence 〉7 days; oxygen dependence 〉28 days and oxygen dependence 〉36 weeks PCA. In years 1 and 2, 25 children were symptomatic and 22 in all 5 years. The patients with subsequent respiratory morbidity were distinguished from those without by requiring longer respiratory support (P 〈 0.05). Logistic regression analysis demonstrated only oxygen dependence beyond 28 days was independently related to subsequent respiratory morbidity (P 〈 0.01). The positive predictive values and likelihood ratios (95% confidence intervals) for positive symptom status in all 5 years were for intermittent positive pressure ventilation 〉7 days 35% (16–53) and 19.5 (1.01–3.76), for oxygen dependency 〉28 days 42% (23–61) and 2.20 (1.45–5.02) and for oxygen dependency 〉36 weeks PCA 35% (13–58) and 1.67 (0.65–4.31). Conclusion Oxygen dependency at 28 days of age remains a useful criterion on which to diagnose “neonatal” chronic lung disease.

    Notizen: Abstract Solubilisation of the dopamine D2 receptor from a membrane preparation of bovine corpus striatum using cholate and NaCl was independently optimised with regard to cholate (0.2%, wt/vol), NaCl (1.5 M), and membrane protein (4 mg/ml) concentrations. A maximum solubilisation yield of 58% was obtained and receptors were measured using a [3H]spiperone binding assay incorporating a polyethylene glycol precipitation step. Soiubilisation was confirmed by ultracentrifugation studies, passage of the receptor through fine-pore filters, increased thermolability, and by retention of the prelabelled receptor on gel filtration. The soluble receptor showed saturability and reversibility of binding. Displacement of [3H]spiperone from the soluble receptor by competing compounds correlated closely with displacement from the membrane-bound receptors. [3H]-Spiperone binding was found to be pH-dependent, with maximum binding occurring at pH 7.8. A comparison of solubilisation was made with six other agents both with and without added NaCl and it was concluded that the cholate/ NaCl solubilisation system provides an efficient, inexpensive, and reliable method for the preparation of functional bovine dopamine D2 receptors.

    Notizen: We investigated the use of measurements of serum concentrations of the cardiac proteins troponins I and T as biochemical markers of myocardial cell damage in 80 patients undergoing vascular or major orthopaedic surgery. Holter electrocardiographic monitoring was carried out before surgery and for 3 days after surgery. Blood samples for troponins I and T and creatine kinase-MB isoenzyme were taken on each of these 4 days. Outcome was assessed at 3 months using a patient questionnaire, general practitioner follow-up and case notes review. Silent postoperative myocardial ischaemia was detected in 21 patients; increases in troponins I and T and creatine kinase-MB occurred in four, six and 17 of these patients, respectively. Eight patients suffered major postoperative complications (cardiac death, myocardial ischaemia, congestive cardiac failure, unstable angina and cerebrovascular accident) and 21 minor complications (poorly controlled hypertension needing increased or new additional treatment, palpitations, increased tiredness or shortness of breath in the absence of known respiratory disease). There were no associations between postoperative ischaemia and cardiac protein concentrations. The relative odds for the associations of major adverse outcome at 3 months after surgery and postoperative ischaemia or increased serum concentrations of the three proteins were 5.39 [95% confidence intervals 1.16–27.67] for postoperative ischaemia; 5.64 [1.07–31.00] for creatine kinase-MB isoenzyme; 17.00 [2.20–116.54] for troponin T and 13.20 [1.12–135.00] for troponin I. We found troponin T to be the only prospective marker for both major and minor cardiovascular complications (relative odds 10.65 [1.26–252.88]).

    Notizen: This study evaluates the quality of life status of 39 male and 21 female Caucasian subjects admitted to a voluntary sector community alcohol detoxification unit. Baseline data including socio-demographics, severity of alcohol dependence and alcohol problems were collected 4–5 days following admission. In addition, the following measures were obtained: Rotterdam Symptoms Checklist, the Beck Depression Inventory, the General Health Questionnaire 12, Chubon's Life Situation Survey and the Nottingham Health Profile. Subjects were followed up at 12 weeks, and subdivided into two groups: relapsers and non-relapsers. A relapse was defined as drinking 21 or more units per week for men and 14 units or more per week for women over 7 consecutive days (1 unit is the equivalent of 8–10 g of absolute ethanol). Fifty-eight (97%) subjects were successfully followed-up, with 36 (62%) of the group relapsing to heavy drinking within 12 weeks. The results show that alcohol dependence is associated with a poor quality of life. Subjects rated poorly on the standardized questionnaires compared with the normative values for their reference populations. Relapsers and non-relapsers differed significantly in their life situation, depression, physical and psychological symptom total scores and the Nottingham Health Profile sub-score energy at 12 weeks compared with baseline, and these changes were investigated for each group. Within the relapse group a linear regression showed no association between any of the quality of life measures and time to relapse. Individual sub-score analysis of the Nottingham Health Profile results point to the importance of sleep, social isolation, pain, physical mobility and anergia in alcohol dependency. There was little change as a result of either not remitting or returning to heavy drinking and overall these findings confirm that alcohol dependent subjects have a poor quality of life.
