Social function in schizophrenia and schizoaffective disorder: associations with personality, symptoms and neurocognition.
(57/397)
BACKGROUND: Research has indicated that stable individual differences in personality exist among persons with schizophrenia spectrum disorders predating illness onset that are linked to symptoms and self appraised quality of life. Less is known about how closely individual differences in personality are uniquely related to levels of social relationships, a domain of dysfunction in schizophrenia more often linked in the literature with symptoms and neurocognitive deficits. This study tested the hypothesis that trait levels of personality as defined using the five-factor model of personality would be linked to social function in schizophrenia. METHODS: A self-report measure of the five factor model of personality was gathered along with ratings of social function, symptoms and assessments of neurocognition for 65 participants with schizophrenia or schizoaffective disorder. RESULTS: Univariate correlations and stepwise multiple regression indicated that frequency of social interaction was predicted by higher levels of the trait of Agreeableness, fewer negative symptoms, better verbal memory and at the trend level, lesser Neuroticism (R2 =.42, p <.0001). In contrast, capacity for intimacy was predicted by fewer negative symptoms, higher levels of Agreeableness, Openness, and Conscientiousness and at the trend level, fewer positive symptoms (R2 =.67, p <.0001). CONCLUSIONS: Taken together, the findings of this study suggest that person-centered variables such as personality, may account for some of the broad differences seen in outcome in schizophrenia spectrum disorders, including social outcomes. One interpretation of the results of this study is that differences in personality combine with symptoms and neurocognitive deficits to affect how persons with schizophrenia are able to form and sustain social connections with others.

Indianapolis I3: the third generation Integrated Advanced Information Management Systems.
(58/397)
In 2001, the Regenstrief Institute for Health Care and the Indiana University School of Medicine (IUSM) began an IAIMS planning effort to create a vision and a tactical plan for the first Integrated Advanced Information Management Systems (IAIMS) implementation to cross a large area and include unaffiliated institutions. A number of elements made this planning effort unique. Among these elements were the existence of a network infrastructure that supported the Indianapolis Network for Patient Care, the existence of a mature medical informatics program at the Regenstrief Institute, and the existence of a wide-area knowledge network fostered by the IUSM libraries. However, the leadership for a strong information technology role in the IUSM that could promote collaboration in support of education and research across the diverse Indianapolis hospital systems had been lacking. By bringing together various groups, each with a commitment to improve health care quality and public health across the Indianapolis metropolitan area, regardless of individual institutional affiliation, the strategic directions for I3-Indianapolis IAIMS Initiative have been defined and the foundations for a third generation IAIMS construct have been laid in Indianapolis, Indiana.

Toward an informal curriculum that teaches professionalism. Transforming the social environment of a medical school.
(59/397)
The social environment or "informal" curriculum of a medical school profoundly influences students' values and professional identities. The Indiana University School of Medicine is seeking to foster a social environment that consistently embodies and reinforces the values of its formal competency-based curriculum. Using an appreciative narrative-based approach, we have been encouraging students, residents, and faculty to be more mindful of relationship dynamics throughout the school. As participants discover how much relational capacity already exists and how widespread is the desire for a more collaborative environment, their perceptions of the school seem to shift, evoking behavior change and hopeful expectations for the future.

Secondary leukemias in refractory germ cell tumor patients undergoing autologous stem-cell transplantation using high-dose etoposide.
(60/397)
PURPOSE: To quantify the risk of secondary leukemias in relapsed testicular cancer patients undergoing autologous stem-cell transplantation with high-dose etoposide. PATIENTS AND METHODS: Single institution, retrospective study of germ cell tumor patients who underwent autologous transplantation using high-dose etoposide from 1987 to 2001. RESULTS: One hundred thirteen patients received high-dose etoposide and carboplatin followed by autologous stem-cell transplantations for germ cell tumors. Follow-up ranged from 12 to 166 months (median, 51 months). Three patients (2.6%; 95% CI, 0.55% to 7.50%) subsequently developed leukemia at an average of 16 months post-autologous transplantation (range, 11 to 21 months). All three had received tandem transplantations and had been heavily pretreated, including at least one prior cycle of etoposide. Following autologous transplantation, all three patients exhibited refractory cytopenias before developing overt leukemia. All leukemias were of myeloid lineage. One patient developed an M2 with a t(8,21) chromosomal translocation; another, an M5 with a t(11,19); and one patient exhibited an unclassified leukemia with cytogenetic abnormalities resulting in monosomy for 7p and partial monosomy of 7q. Treatment of the leukemias involved allogeneic bone marrow transplantation. CONCLUSION: High-dose chemotherapy using high-dose etoposide as therapy for relapsed germ cell tumors was associated with a 2.6% risk of developing a secondary myeloid leukemia. This figure was not significantly different from the expected rate of secondary leukemias when patients receive additional cycles of standard-dose etoposide as salvage chemotherapy for germ cell tumors. Other factors, including the use of platinum agents, may also have a role in leukemogenesis in this patient population. (+info)
A clinical and echocardiographic score for assigning risk of major events after dobutamine echocardiograms.
(61/397)
OBJECTIVES: We sought to develop and validate a risk score combining both clinical and dobutamine echocardiographic (DbE) features in 4890 patients who underwent DbE at three expert laboratories and were followed for death or myocardial infarction for up to five years. BACKGROUND: In contrast to exercise scores, no score exists to combine clinical, stress, and echocardiographic findings with DbE. METHODS: Dobutamine echocardiography was performed for evaluation of known or suspected coronary artery disease in 3156 patients at two sites in the U.S. After exclusion of patients with incomplete follow-up, 1456 DbEs were randomly selected to develop a multivariate model for prediction of events. After simplification of each model for clinical use, the models were internally validated in the remaining DbE patients in the same series and externally validated in 1733 patients in an independent series. RESULTS: The following score was derived from regression models in the modeling group (160 events): DbE risk = (age.0.02) + (heart failure + rate-pressure product <15000).0.4 + (ischemia + scar).0.6. The presence of each variable was scored as 1 and its absence scored as 0, except for age (continuous variable). Using cutoff values of 1.2 and 2.6, patients were classified into groups with five-year event-free survivals >95%, 75% to 95%, and <75%. Application of the score in the internal validation group (265 events) gave equivalent results, as did its application in the external validation group (494 events, C index = 0.72). CONCLUSIONS: A risk score based on clinical and echocardiographic data may be used to quantify the risk of events in patients undergoing DbE. (+info)
Legal and public policy responses of states to bioterrorism.
(62/397)
In late 2001, during the aftermath of the anthrax letter attacks, model legislation was proposed to relevant state agencies to update their states' public health laws to meet the threat of bioterrorism. This legislation was the Model State Emergency Health Powers Act. A concern underlying this and related efforts to address future bioterrorism threats was the perceived inadequacy of state laws to respond effectively when such threats occur. We evaluated how 4 states--Utah, Maine, South Dakota, and Indiana--addressed this concern in the context of the model legislation. The conclusion is that the model legislation generally served as an important catalyst for state action in the field of bioterrorism preparation. (+info)
Syphilis testing in association with gonorrhea/chlamydia testing during a syphilis outbreak.
(63/397)
We used an electronic medical records system retrospectively to evaluate how frequently, in a public hospital and its clinics, combined gonorrhea/chlamydia tests were accompanied by a syphilis test before and during a syphilis outbreak. Among 70,330 gonorrhea/chlamydia tests (1996-2000), the proportion with a syphilis test increased from 13% (preoutbreak) to 50% (intervention period) for men and from 6% to 13% for nonpregnant women. The increased syphilis testing coincided with a multifaceted public health intervention. (+info)
Use of the silastic sheath in bladder neck reconstruction.
(64/397)
OBJECTIVE: The study compared two populations of patients undergoing bladder neck reconstruction using the silastic sheath in two major pediatric centers. The success with this technique was markedly different in the two centers. The purpose of the study was to determine factors that might explain the divergent results. PATIENTS AND METHODS: Fifteen patients treated in Indianapolis were compared with 94 patients treated in London with the silastic sheath technique of bladder neck reconstruction. Eighty-seven percent of the Indianapolis patients had myelomeningocele whereas 86% of the London group had exstrophy/epispadias. Median age of the Indianapolis patients was 11 years whereas it was 8.4 years in London. Seventy-three percent of patients in Indianapolis were female and 79% in London were male. Patients were followed for a minimum of eight years in Indianapolis and a mean of seven years in London. Similar surgical technique was employed in the two centers but, over time, the London approach included use of a non-reinforced silastic wrapped loosely around the bladder neck with the interposition of omentum. RESULTS: Both groups achieved continence rates exceeding 90%. Of the Indianapolis patients, two-thirds experienced erosion of the silastic at a mean of 48 months. With modifications in the London technique, the erosion rate of silastic was lowered from 100% to 7%. CONCLUSION: Direct, snug wrap of silastic without omentum around the Young-Dees tube as well as simultaneous bladder augmentation placed patients at increased risk for erosion. The silastic sheath technique may be less applicable to myelomeningocele patients. It seems most applicable to older male patients with exstrophy or epispadias undergoing Young-Dees bladder neck reconstruction who have the ability to void. (+info)
