Soluble tumour necrosis factor receptors,tumour necrosis factor and interleukin-6 in serum in granulocytopenic patients with fever

Serum levels of TNF, IL-6 and soluble TNF receptors p55 and p75 (sTNFR-p55 and sTNFR-p75) were examined in 14 patients with acute myeloid leukaemia during 43 courses of chemotherapy. The patients experienced 30 episodes of fever which occurred during granulocytopenia (defined as granulocyte counts <0.2×10⁹/1) and six fever episodes when granulocyte counts were >1.0×10⁹/1. Febrile episodes were classified as microbiologically defined infection, clinically defined infection, and unexplained fever. Levels of bioactive IL-6 and immunoreactive TNF increased in response to fever during granulocytopenia, whereas bioactive TNF was not detected in any sample in this study. During granulocytopenia, both sTNFR rose significantly in microbiologically defined infection (P<0.01 for sTNFR-p55 and P<0.05 for sTNFR-p75), but not in the other two categories. The ratio of sTNFR-p55 to sTNFR-p75 was higher during febrile periods in granulocytopenia than in a non-granulocytopenic situation with granulocyte counts >1.0×10⁹/1 (P<0.01). We conclude that granulocytopenia affects release of the two sTNFR differently during febrile periods, and that release of sTNFR-p75 in response to fever is reduced during granulocytopenia, suggesting a role for the granulocytes in systemic release of sTNFR-p75.     

Rehabilitation and quality of life in diabetic patients after successful pancreas-kidney transplantation

Twenty-seven Type I diabetic patients in end-stage renal failure were followed after combined pancreas-kidney transplantation. All patients received duct-occluded segmental pancreas grafts. Clinical progression of extrarenal diabetic complications was studied in 11 patients with long-term functioning pancreatic and renal transplants (Group 1), and in 16 patients who had lost pancreatic graft function, but retained renal graft function (Group 2). Pretransplant, extrarenal diabetic complications were equally distributed in the two groups. In the follow-up period, however, the progress of these complications was less severe in patients with functioning pancreatic transplants. No differences were found between the groups concerning rehabilitation, working capacity, need of help or hospital admittance. It is suggested that pancreas transplantation performed in an earlier stage of diabetes before serious complications have developed, would probably improve rehabilitation and quality of life in these patients.     

Effects on nurse retention. An experiment with scheduling

Four randomly selected nursing groups were assigned to three experimental groups and one control group to test the relative impact of three experimental nursing schedules, using a before-after design. The three experimental treatments were straight shifts; regular schedule but with unlimited requests for changes; and individual station-designed schedules. Before treatment, score differences between the experimental and control groups were limited to one of 36 highly reliable scales specifically constructed and pretested to gauge effects of scheduling. This single difference was judged not to be significantly related to experimental outcomes. Because of a poor job market situation, retention was not affected significantly by any of the three treatments, but root causes of turnover were. Results of the experiment showed that individual station-designed schedules triggered the most changes that favor retention. In contrast, the other two treatments unexpectedly increased nurses' own sense of marketability and reduced teamwork among nurses. Reasons accounting for the results are discussed in the text.     

Somatic health among heroin addicts before and during opioid maintenance treatment: a retrospective cohort study

Background  

The long-term impact of opioid maintenance treatment (OMT) on morbidity and health care utilization among heroin addicts has been insufficiently studied. The objective of this study was to investigate whether health care utilization due to somatic disease decreased during OMT, and if so, whether the reduction included all kinds of diseases and whether a reduction was related to abstinence from drug use.     

Improvement of post-transplant lymphocele treatment in the laparoscopic era

Post-transplant lymphoceles are a common problem after renal transplantation, often inflicting the graft or adjacent iliac veins. Since 1991, there have been many reports on laparoscopic fenestration as the treatment of choice, but no larger series has been presented. At our department, 63 laparoscopic procedures were performed between 1993 and 2001 among 1502 renal graft recipients. The laparoscopic operation time, conversion rate, hospital stay, and complications have all decreased progessively. Duration of hospital stay and convalescence was markedly longer in patients treated with conventional open surgery (27 patients). Rejections, CMV disease, and post-transplant reoperations seem to have an increased incidence in the lymphocele population. According to our experience, laparoscopic fenestration is the superior treatment for symptomatic lymphoceles, allowing minimal trauma and fast recovery. Our series suggests that the rate of complications/graft injury decreases progressively with experience. Laparoscopic ultrasound seems useful in difficult cases. Prophylactic measures should be emphasised at the time of transplantation and reoperations.     

Self-reported weight, weight goals, and weight control strategies of a midwestern population

OBJECTIVE: To elicit from individuals in a population their current weight and height, weight goals, and weight control strategies to aid in design of effective interventions to prevent and treat obesity. SUBJECTS AND METHODS: By random digit dial telephone survey, 1224 adult residents of Olmsted County, Minnesota, were contacted between February 28 and May 5, 2000. They self-reported weights and weight goals and described physical characteristics associated with their desire to lose weight. RESULTS: Among the 1224 respondents, 65.6% of men and 47.9% of women reported that they were overweight (body mass index [BMI], 25.0-29.9 kg/m2) or obese (BMI, > or =30.0 kg/m2). Only 0.4% of men and 3.7% of women reported that they were underweight (BMI, <18.5 kg/m2). Of the respondents 72.6% of men and 85.1% of women reported that they were either trying to lose or not gain weight. The average weight loss goal for individuals trying to lose weight was 23.4 pounds for men and 28.0 pounds for women. Only one third of individuals trying to lose weight and one fifth of individuals trying not to gain weight reported using the recommended approach of combining energy restriction with at least 150 minutes of exercise per week. CONCLUSIONS: The prevalence of overweight and obesity in the population and the underutilization of combining both restricting energy intake and exercising at least 150 minutes per week for weight control is high. Like the majority of people in the United States, the majority of people in Olmsted County desire to control their weight. The community has responded with plans to help residents meet their goals, although efficacy and outcomes remain to be determined.     

PSYCHOLOGICAL EFFECTS OF AN EPIDEMIOLOGICAL STUDY OF BENIGN PROSTATIC HYPERTROPHY

SUMMARY The psychological impact of an epidemiological study of benign prostatic hypertrophy (BPH) was assessed in a representative sample of practice list patients. Of the 889 men completing a general health self-report questionnaire previously validated in a screening programme, 75% knew nothing of problems of the prostate, and 84.5% were not at all worried about prostate problems prior to commencement of the study. Receiving the letter of invitation and the procedures neither increased nor reduced anxiety levels for 69% and 70% respectively. In the 227 men referred to hospital for further investigation the procedure increased anxiety in 28%, decreased anxiety in 20%, and had no effect on the remainder. The sample of 137 (16%) men who, prior to interview, were in some way worried about problems of the prostate had significantly more urinary tract symptoms than those who were not at all worried about prostatic problems. Despite being worried about prostatic problems and having significant urinary symptoms, this group was no more likely to have attended a GP for investigation and/or treatment. Results are discussed in relation to the possible psychological effects of general health screening and the reluctance of men to attend for consultation despite awareness and concern regarding urinary symptomatology.     

Clinical Problems in Atrial Synchronous Ventricular Inhibited Pacing: A Long-term Follow-up of 54 Patients

Fifty-four VDD-paced patients were followed for more than 12 months; they were studied retrospectively in order to assess possible clinical problems and their management. The patients were between 19 and 84 years of age (mean, 66 +/- 11). Twenty-four of the 54 received a VDD pacemaker as a primary implant and 30 had had VVI pacemakers which were changed to VDD mainly because of limited exercise tolerance or symptoms of AV asynchrony. The follow-up time was between 12 and 69 months (mean, 39 +/- 17). Pacemaker and lead problems were neither frequent nor serious. Six patients had spontaneous paroxysmal supraventricular tachyarrhythmias, four had pacemaker-mediated supraventricular tachycardias and six had ventricular tachyarrhythmias. Treatment of tachyarrhythmias included drugs, DC conversion, reprogramming, or combinations of these measures. Frequency of hospitalization was not greater than expected. In conclusion, VDD pacing appears safe and reliable, with problems mainly associated with the underlying cardiac disease rather than to the pacing mode itself.
