A patient without evident immune deficiency who received a transfusion of blood from a second-degree family member developed fatal transfusion- associated graft-versus-host disease (TA-GVHD). The donor was homozygous for an HLA haplotype for which the recipient was heterozygous (one-way HLA match). All 39 reported cases of TA-GVHD in immunocompetent patients were reviewed to ascertain the predisposing factors and to define the indications for irradiating blood for this population. HLA typing was described in 15 cases; in 13, including seven related and six unrelated donors, a one-way HLA match was present. Thirty-one (79%) of the 39 cases were reported from Japan (and 196 other cases are cited in the Japanese literature), but a one-way HLA match among unrelated donors at HLA-A, -B, -DR loci is only approximately two to four times more likely in Japanese persons than in whites. Fresh blood (< 96 hours old) was used in 29 (94%) of the 31 cases reported from Japan and in 33 (87%) of 38 cases overall (in one case, the age of the blood used was not reported). Thus, factors that appear to predispose to TA-GVHD in immunocompetent patients are a one- way HLA match, fresh blood, and, possibly, Japanese ancestry. Irradiating cellular blood components from all blood relatives of transfusion recipients will not completely eliminate the risk of TA- GVHD. 相似文献

Background. Delivery of home parenteral nutrition (PN) is typically cycled over 12 hours. Discharge to home on PN is often delayed due to potential adverse events (AEs) associated with cycling PN. The purpose was to determine whether patients requiring long‐term PN can be cycled from 24 hours to 12 hours in 1 day instead of 2 days without increasing the risk of PN‐related AEs. Methods. Hospitalized patients receiving PN at goal calories infused over 24 hours without severe electrolyte or blood glucose abnormalities were eligible. Patients were randomly assigned to a 1‐step “fast‐track” protocol or 2‐step “standard” protocol. AEs were defined as hypoglycemia or hyperglycemia, new‐onset or worsening dyspnea, tachycardia, tachypnea, lower extremity or sacral edema, pulmonary edema, or abdominal ascites and were graded as minor or major. Results. In the 63 patients studied, the most prevalent PN‐related AE was hyperglycemia, occurring in 24.2% and 30.0% of patients in the fast‐track and standard groups, respectively. Overall, there was no significant difference in the prevalence of PN‐related minor AEs between fast‐track and standard groups (33.3% and 53.3%, P = .5). No major PN‐related AEs occurred in the fast‐track group, while 1 major PN‐related AE (pulmonary edema) occurred in the standard group. Conclusions. Fast‐track cycling is as safe as standard cycling in patients without diabetes mellitus or major organ dysfunction requiring long‐term PN. Fast‐track cycling could potentially expedite hospital discharge, resulting in decreased healthcare costs and improved patient satisfaction. 相似文献

OBJECTIVE: A sense of optimism, which derives from the ways individuals explain causes of daily events, has been shown to protect health, whereas pessimism has been linked to poor physical health. We examined prospectively the relationship of an optimistic or pessimistic explanatory style with coronary heart disease incidence in the Veterans Affairs Normative Aging Study, an ongoing cohort of older men. METHODS AND RESULTS: In 1986, 1306 men completed the revised Minnesota Multiphasic Personality Inventory, from which we derived the bipolar revised Optimism-Pessimism Scale. During an average of 10 years of follow-up, 162 cases of incident coronary heart disease occurred: 71 cases of incident nonfatal myocardial infarction, 31 cases of fatal coronary heart disease, and 60 cases of angina pectoris. Compared with men with high levels of pessimism, those reporting high levels of optimism had multivariate-adjusted relative risks of 0.44 (95% confidence interval = 0.26-0.74) for combined nonfatal myocardial infarction and coronary heart disease death and 0.45 (95% confidence interval = 0.29-0.68) for combined angina pectoris, nonfatal myocardial infarction, and coronary heart disease death. A dose-response relation was found between levels of optimism and each outcome (p value for trend,.002 and.0004, respectively). CONCLUSIONS: These results suggest that an optimistic explanatory style may protect against risk of coronary heart disease in older men. 相似文献

ObjectiveThe objective of this study was to learn about the experiences of principals and school food service directors with the Texas Public School Nutrition Policy.DesignSemistructured qualitative interviews were conducted to gain first hand reactions to the new nutrition policy.SettingData were gathered from Texas middle schools.ParticipantsPrincipals and food service directors from 24 schools randomly selected from 10 Texas Education regions were interviewed.Phenomenon of InterestParticipants were interviewed about their reactions to the implementation of the Texas School Nutrition Policy.AnalysisTwo researchers, using thematic analysis, independently analyzed each interview. Differences in coding were reconciled and themes were generated.ResultsThe themes that surfaced included resistance to the policy, policy development process, communication, government role, parental role, food rewards, fund raising, and leadership.Conclusions and implicationsResistance to the policy was not extreme. In the future a wider array of school personnel who are affected by school food regulations should be included in the development of new policies. It is critical to communicate with all concerned parties about the policy. 相似文献
