RESUMO
OBJECTIVES: In this study patients with documented ischemic coronary heart disease (ICHD; prior MI or CAD per catheterization) were tested for the association of various measures of emotional distress with Age at Initial Diagnosis. METHODS: The measures were chosen because of a published track record at predicting mortality in this population. Females were oversampled to achieve equivalent numbers of each sex (n=50), and thus equivalent statistical power. In a subset of patients (38 males and 32 females), Spouse/Friend Ketterer Stress Symptom Frequency Checklists (KSSFCs) were received. RESULTS: Females reported more depression and anxiety than males. However, spouses or friends reported more anger for males. Denial (spouse/friend minus self-ratings) was greater in males for all three scales of the KSSFC (Anger, P=.005; Depression, P=.024; Anxiety, P=.001). Although females showed the same trend, self and spouse or friend ratings of distress were significantly associated with Age at Initial Diagnosis only in males. When split at the sample mean on the Spouse/Friend KSSFC AIAI (Anger) scale, Age at Initial Diagnosis occurred 14.2 years earlier in males. CONCLUSIONS: Use of a significant other in assessing psychosocial/emotional distress in males may confer greater accuracy, and therefore predictive power for clinical endpoints.

OBJECTIVE: This meta-analysis evaluated the types of lifestyle treatments used in published obesity drug studies and assessed their contribution to weight losses associated with pharmacological interventions. RESEARCH METHODS AND PROCEDURES: Randomized, placebo-controlled, double-blind clinical trials of anti-obesity agents that are/were Food and Drug Administration-approved for the treatment of obesity (both prescription and over-the-counter), and drugs that are Food and Drug Administration-approved and are used off-label for obesity were included. Studies were located by computer searches of databases (e.g., Medline, PsychInfo) and reviewing tables of content/reference sections of journals, abstracts, previous reviews, past empirical studies, relevant book chapters, and recent issues of journals that regularly publish obesity research. In addition, a number of individuals who regularly publish in the obesity literature were asked to provide personal lists of obesity-drug studies. Based on the above criteria, a total of 108 randomized clinical trials were located. RESULTS: Balanced-deficit diets, low-calorie diets, and self-monitoring were the most used lifestyle treatments in published obesity studies. They were incorporated into 40.7%, 25%, and 23.1% of pharmacotherapy studies, respectively. Physical activity and other behavioral or psychotherapeutic interventions rarely were used. A substantial portion of weight loss experienced by patients was attributable to both "placebo effects" and to the lifestyle treatments. DISCUSSION: Obesity-pharmacotherapy trials do not use lifestyle treatments with the frequency expected based on the official positions of most professional organizations concerned with the comprehensive management of obesity.

Treatment of psychosocial/emotional distress as a strategy for diminishing chest pain in such patients remains entirely unutilized in standard care. Sixty-three patients with known or suspected CAD were entered in an aggressive lifestyle modification program. Patients completed the Symptom Checklist 90-Revised (SCL90R) at the diagnostic interview session, at 3 and at 12 months. Statistically significant drops were observed on multiple scales of the SCL90R at both 3 and 12 months. An item from the SCL90R was used as a proxy for angina. Multiple measures of emotional distress at baseline were found to correlate with chest pain at baseline, but not a number of traditional cardiovascular risk factors. The chest pain item displayed improvement at both 3 and 12 months. Improvement on all scales of the SCL90R correlated with improvement in chest pain. It may be possible to control chest pain in some CAD patients with psychosocial interventions.

BACKGROUND: Psychosocial/emotional distress has been repeatedly found to be a correlate of the onset/aggravation of ischaemic heart disease. METHODS: Eighty-three patients (63 men and 20 women) with known coronary artery disease who entered an aggressive lifestyle modification programme were administered a clinical/demographic history and the Symptom Checklist 90--Revised at baseline. Several measures of social isolation/alienation (shyness/self-consciousness, feeling lonely, feeling abused and overall) were derived from the the Symptom Checklist 90--Revised. RESULTS: Univariate tests of the association of known cardiovascular risk factors and the Symptom Checklist 90--Revised scales with age at initial diagnosis yielded several significant results for history of hypercholesterolaemia (P = 0.018), history of hypertension (P = 0.030), somatization (P = 0.007), obsessive-compulsive (P = 0.009), depression (P = 0.006), anxiety (P = 0.021), hostility (P = 0.003), paranoia (P = 0.050), psychoticism (P = 0.029), the Global Severity Index (P = 0.007), the Positive Symptom Distress Index (P = 0.005), the Positive Symptom Total Score (P = 0.003) and feeling abused (P = 0.037). Only history of hypertension, history of hypercholesterolaemia and the hostility scale (overall F = 6.08 and P = 0.0009) emerged as unique correlates of age at initial diagnosis in a multiple regression using only the significant univariate predictors. CONCLUSIONS: Psychosocial factors are sufficiently confounded with one another that they lose their predictive value once one is entered in the equation. High scores on the hostility scale were associated with a 5.7 year differential in age at initial diagnosis. The younger a patient is at initial diagnosis, the more likely he/she is to have high levels of emotional distress.

OBJECTIVE: Our investigation was designed to use maternal serum alpha-fetoprotein and individual or combinations of ultrasonographic parameters to examine the influence of fetal gender on the prediction of Down syndrome. STUDY DESIGN: A cohort study of 5114 patients who underwent karyotype analysis between 13 and 22 weeks' gestation was undertaken. Maternal demographic variables, anthropometric indices, and maternal serum alpha-fetoprotein values were assessed. Fetal parameters recorded included gender, biparietal diameter, head circumference, femoral and humeral length, transverse cerebellar diameter, and nuchal fold thickness. The effect of fetal gender on maternal serum alpha-fetoprotein values and ultrasonographic parameters was assessed. Gender-specific differences between fetuses with Down syndrome and euploid fetuses were identified, and the optimal cutoff values of individual and combinations of biometric parameters were determined by receiver operating characteristic curve analysis. RESULTS: A total of 42 fetuses with Down syndrome were identified. Female fetuses with Down syndrome had significantly lower maternal serum alpha-fetoprotein values than their male counterparts, and maternal serum alpha-fetoprotein screening paradigms resulted in the disproportionate identification of affected female fetuses. A nuchal fold thickness > or = 5 mm was the single best ultrasonographic predictor of Down syndrome independent of fetal gender. Affected male fetuses had significantly smaller mean femoral and humeral lengths than euploid fetuses after adjustment for biparietal diameter, but only the humeral length proved a clinically useful predictor of Down syndrome. Pearson's correlation coefficient confirmed that nuchal fold thickness and humeral length were independent of each other and of maternal age and maternal serum alpha-fetoprotein levels. The optimal ultrasonographic predictor of Down syndrome was the presence of either a nuchal fold thickness > or = 6 mm or a humeral length > 3.5 to 3.7 mm below the expected value. This combination of ultrasonographic findings identified 41.7% of female and 66.7% of male fetuses with Down syndrome. CONCLUSIONS: Fetal gender affects the prediction of Down syndrome by both maternal serum alpha-fetoprotein and ultrasonographic parameters. Moreover, the ultrasonographic detection of Down syndrome in fetuses is greatly improved by a combination of gender-specific biometric parameters.

Electron spin relaxation rates over the temperatue range 1.41-15.6 K are presented for the copper-containing protein plastocyanin. Measurements are described for two samples, each derived from a different preparation of equivalent purity, for which the ionic, redox, and protein compositions varied slightly. X-band data are analyzed in terms of a phonon-limited direct process and a Raman relaxation process, where the index of the Raman transport integral is treated as a fitting parameter. Both samples yield rate data at the highest temperatures that are characterized by small deviations from a simple T(n) power law dependence, with n in the range 4.8-5.2. These deviations are most easily quantified when the T(n) power law fits are compared with similar functions that allow for a finite cutoff in the phonon density of states corresponding to Debye temperatures between 90 and 100 K with n in the range 5.0-5.5.
RESUMO
The present study combined a multiple category observational data system with a correlational analysis in order to test the value of such a combination as an ecobehavioral assessment instrument and determine whether this package would reveal relationships both between and within the behavioral repetoires of several children. Four severely and profoundly mentally retarded children between the ages of 9 and 12 years were observed in their self-contained special education classroom, and the teacher collected the data over a 20-day period using an interval recording system. Bivariate correlational analysis of the 38 observed categories with the school-day as the unit of analysis revealed significant relationships both between and within children. Two children showed a pattern of relationships in which social interaction in either child was associated with maladaptive behavior in the other, and another child's destructive and self-injurious behaviors were positively associated with his noncompliance. Patterns of related child behaviors suggested ways in which they may have been affected by the behavior of adults in the classroom. The value of such an instrument for ecological assessment is discussed.

A prospective controlled comparison of portal-systemic (PSS) and distal splenorenal shunts (DSRS) in cirrhotic patients who had survived hemorrhage from esophagogastric varices was undertaken 5 yr ago at five hospitals by the Boston-New Haven Collaborative Liver Group. The clinical and endoscopic criteria for massive hemorrhage were satisfied in 155 patients. Thirty-four patients were excluded, primarily because of uncontrolled hemorrhage. Thirty-four were rejected because the were poor operative risks and 21 because they did not satisfy criteria. Thirteen patients refused to participate; the remaining 53 were randomized; 29 to receive PSS and 24, DSRS. The two groups were similar in clinical, laboratory, and manometric characteristics. The DSRS group was older and tended to have had more previous hemorrhages. Followup ranged from 1 to 56 months (mean 21). After PSS, which was performed by 10 different surgeons, 6 patients died during the hospital admission (21%) compared to 2 after DSRS (12%). There were 6 late deaths in the PSS group and 4 in the DSRS group. Portal-systemic encephalopathy occurred in 5 of the 23 survivors of PSS (23%), and in 6 of the 19 who survived DSRS (32%. Two patients in the PSS group bled (9%), 1 after thrombosis and 1 after stenosis of the shunt. Three patients in the DSRS group bled (16%) and all had thrombosis of the shunt. PSS was associated with an unexplained but inordinately high operative mortality. Although the DSRS was accomplished with an acceptably low operative mortality, it was associated with frequent portal-systemic encephalopathy, shunt occlusion, and recurrent hemorrhage. Similar incidences of portal-systemic encephalopathy, shunt occlusion, and recurrent hemorrhage were observed in the PSS group. More patients and longer followup are necessary to determine which of these portal decompressive procedures is superior.
