Indium-111 labeled platelet deposition following transfemoral angiography

The incidence of thromboembolitic events in patients undergoing transfemoral angiography was examined using indium-111 labeled platelets. Twenty-seven patients received approximately 300 muCi of autologous labeled platelets at least 3 hours before angiography and were scanned with a gamma camera immediately before and after angiography. All patients were free of clinically obvious complications in the 1-2 day period after angiography. Our results showed evidence of platelet deposition at 21 sites other than the puncture site in 12 (44%) patients. Most platelet deposition (54%) occurred along the region between the puncture site and the aortic bifurcation; 24% occurred at sites not traversed by the catheter. At the puncture site itself, there was substantial platelet uptake in 44% of patients. This study indicates the need for further work in determining the most suitable catheter material and in assessing the efficacy of other measures such as anticoagulant or antiplatelet therapy.     

Cardiac rehabilitation in patients with severe ischemic left ventricular dysfunction

Twenty patients who had had a myocardial infarction and who had a resting left ventricular ejection fraction of 25% or less participated in an 8-week outpatient supervised exercise and education program. No morbidity or mortality occurred during the program, and most patients achieved a substantial improvement in exercise capacity. During a follow-up interval of a mean of 29.7 +/- 13.0 months, four patients died, an annualized mortality of 8 +/- 4%. The outcome of cardiac rehabilitation was assessed 19.1 +/- 4.4 months after completion of the supervised program. Of the 16 survivors, all of whom had been fully employed before their most recent myocardial infarction, 9 (56%) had returned to full-time work, 6 (38%) were medically disabled, and 1 was retired (age 73 years) but fully active. Of the 16 survivors, 13 (81%) completed a questionnaire about their perceptions of their current quality of life. Of the 13 patients, 12 (92%) had continued to exercise regularly. Four patients (31%) reported the ability to perform all desired activities without symptoms, whereas nine patients (69%) noted some impairment in their functional capacity. Thus, in this group of patients with profound left ventricular dysfunction, the rehabilitation potential, as evidenced by return to productive employment and the ability to perform desired activities-including exercise training-was generally favorable.     

Incidence and mortality of venous thrombosis: a population-based study

Background: Estimates of the incidence of venous thrombosis (VT) vary, and data on mortality are limited. Objectives: We estimated the incidence and mortality of a first VT event in a general population. Methods: From the residents of Nord‐Trøndelag county in Norway aged 20 years and older (n = 94 194), we identified all cases with an objectively verified diagnosis of VT that occurred between 1995 and 2001. Patients and diagnosis characteristics were retrieved from medical records. Results: Seven hundred and forty patients were identified with a first diagnosis of VT during 516 405 person‐years of follow‐up. The incidence rate for all first VT events was 1.43 per 1000 person‐years [95% confidence interval (CI): 1.33–1.54], that for deep‐vein thrombosis (DVT) was 0.93 per 1000 person‐years (95% CI: 0.85–1.02), and that for pulmonary embolism (PE) was 0.50 per 1000 person‐years (95% CI: 0.44–0.56). The incidence rates increased exponentially with age, and were slightly higher in women than in men. The 30‐day case‐fatality rate was higher in patients with PE than in those with DVT [9.7% vs. 4.6%, risk ratio 2.1 (95% CI: 1.2–3.7)]; it was also higher in patients with cancer than in patients without cancer [19.1% vs. 3.6%, risk ratio 3.8 (95% CI 1.6–9.2)]. The risk of dying was highest in the first months subsequent to the VT, after which it gradually approached the mortality rate in the general population. Conclusions: This study provides estimates of incidence and mortality of a first VT event in the general population.     

Management of lipids in primary and secondary prevention of cardiovascular diseases

Although the frequency of cardiovascular disease is declining, it remains a major present and future threat to health in the United States. The deleterious effects of abnormal blood lipid concentrations have long been recognized, but the benefit of corrective intervention in this process has only recently been demonstrated. We review the major lipid abnormalities and the available clinical therapeutic interventions. In addition, we discuss data that address the premise that reducing low-density lipoprotein cholesterol or raising high-density lipoprotein cholesterol should decrease the progression of coronary atherosclerosis, and we summarize drug trials in which clofibrate, niacin, cholestyramine, and gemfibrozil decreased coronary heart disease events. Studies that used cholestyramine and the combination of colestipol and niacin resulted in decreased progression of coronary artery disease. On the basis of early experience with lovastatin, inhibitors of hydroxymethylglutaryl-coenzyme A reductase are likely to be effective in the treatment of hypercholesterolemia. The available information on the association of low cholesterol levels and cancer suggests that low total cholesterol is a consequence rather than a cause of carcinoma. Current data strongly support the concept of vigorous intervention directed at management of lipids, both with non-pharmacologic treatment and with drug therapy, for the primary and secondary prevention of coronary atherosclerosis.     

The development and evaluation of a web-based programme to support problem-solving skills following brain injury

Background and aim: Cognitive impairments following brain injury, including difficulty with problem solving, can pose significant barriers to successful community reintegration. Problem-solving strategy training is well-supported in the cognitive rehabilitation literature. However, limitations in insurance reimbursement have resulted in fewer services to train such skills to mastery and to support generalization of those skills into everyday environments. The purpose of this project was to develop and evaluate an integrated, web-based programme, ProSolv, which uses a small number of coaching sessions to support problem solving in everyday life following brain injury.

Method: We used participatory action research to guide the iterative development, usability testing, and within-subject pilot testing of the ProSolv programme. The finalized programme was then evaluated in a between-subjects group study and a non-experimental single case study.

Results: Results were mixed across studies. Participants demonstrated that it was feasible to learn and use the ProSolv programme for support in problem solving. They highly recommended the programme to others and singled out the importance of the coach. Limitations in app design were cited as a major reason for infrequent use of the app outside of coaching sessions.

Conclusions: Results provide mixed evidence regarding the utility of web-based mobile apps, such as ProSolv to support problem solving following brain injury.

• Implications for Rehabilitation

• People with cognitive impairments following brain injury often struggle with problem solving in everyday contexts.

• Research supports problem solving skills training following brain injury.

• Assistive technology for cognition (smartphones, selected apps) offers a means of

• supporting problem solving for this population.

• This project demonstrated the feasibility of a web-based programme to address this need.

     

An experience applying Gua-Sha to help a parturient women with breast fullness

This paper was designed to describe the experience of nurses who applied Gua-Sha, a traditional Asian healing technique, in caring for a parturient woman suffering from breast fullness. The caring period ran from the second day postpartum through the mother's discharge from the hospital, and included telephone follow up during the first and second postpartum weeks. Main caring activities included: (1) supporting and reinforcing the mother's confidence to encourage continued breastfeeding; (2) making sure the baby suckled in a good position and that the mother mastered proper breastfeeding techniques; (3) applying Gua-Sha to help breast milk expression and reduce the breast fullness discomfort; and (4) following up regularly on breastfeeding and breast fullness conditions. As a result, the mother was able to continue breastfeeding and could eventually take care of herself, thus achieving a satisfactory breast feeding experience.
