The purpose of this cross-sectional analysis of the National Violence Against Women Survey was to characterize current symptoms of posttraumatic stress disorder (PTSD) among 185 men and 369 women survivors of intimate partner violence (IPV). In this subsample, 24% of women and 20% of men had current moderate-to-severe PTSD symptoms. PTSD scores were higher for women than men. Protective factors that appear to increase resiliency of survivors were higher education and income, being currently married, and reporting that IPV had stopped. Higher physical or psychological IPV scores, current depressive symptoms, and the survivor having left the relationship at least once were associated with risk of moderate-to-severe symptoms of PTSD. Protective factors may be used to boost resiliency of IPV survivors and reduce PTSD symptoms.

Metabolic investigations often utilize arteriovenous sampling and muscle biopsy. These investigations represent some risk to the subject. We examined 369 studies performed in the General Clinical Research Center between January 1994 and May 2003 for events related to femoral catheterization and muscle biopsies. Incidents were further examined by age (younger: 18-59 yr, n=133; and older: 60-76 yr, n=28). There were no clinically defined major complications associated with either procedure. The incidence of femoral catheter repositioning or reinsertion was higher in the older group (25.5 vs. 9.7%). There was no difference in the incidence of premature removal of catheters, ecchymosis or hematoma, or the persistence of pain after discharge. The occurrence of all incidents did not increase with multiple catheterizations. Muscle biopsy was associated with infrequent ecchymosis or hematoma in both groups (1.1 and 3.6% in younger and older groups, respectively). Both procedures entail a small likelihood of a vagallike response (3.3% overall), resulting in nausea, dizziness, and rarely a loss of consciousness. These results indicate that, in skilled hands and a defined clinical setting, the incidents associated with femoral catheterization and muscle biopsy in healthy volunteers are reasonable and largely controllable.

Debilitating injury is accompanied by hypercortisolemia, muscle wasting, and disruption of the normal anabolic response to food. We sought to determine whether acute hypercortisolemia alters muscle protein metabolism following ingestion of a potent anabolic stimulus: essential amino acids (EAA). A 27-h infusion (80 microg. kg(-1). h(-1)) of hydrocortisone sodium succinate mimicked cortisol (C) levels accompanying severe injury (>30 microg/dl), (C + AA; n = 6). The control group (AA) received intravenous saline (n = 6). Femoral arteriovenous blood samples and muscle biopsies were obtained during a primed (2.0 micromol/kg) constant infusion (0.05 micromol. kg(-1). min(-1)) of l-[ring-(2)H(5)]phenylalanine before and after ingestion of 15 g of EAA. Hypercortisolemia [36.5 +/- 2.1 (C + AA) vs. 9.0 +/- 1.0 microg/dl (AA)] increased postabsorptive arterial, venous, and muscle intracellular phenylalanine concentrations. Hypercortisolemia also increased postabsorptive and post-EAA insulin concentrations. Net protein balance was blunted (40% lower) following EAA ingestion but remained positive for a greater period of time (60 vs. 180 min) in the C + AA group. Thus, although differences in protein metabolism were evident, EAA ingestion improved muscle protein anabolism during acute hypercortisolemia and may help minimize muscle loss following debilitating injury.

Two experiments examined the effects of methylphenidate in male and female patients enrolled in an outpatient treatment program for primary cocaine dependence. The first study was a component of a double-blind efficacy trial wherein 57 patients were first tested in a human laboratory for their initial responsiveness to medication. Patients were randomly assigned to receive either placebo or methylphenidate treatment and received their first dose in the human laboratory environment before continuing in outpatient treatment. Methylphenidate was given as a 20-mg sustained-release dose (twice daily) plus an additional 5-mg immediate-release dose combined with the morning dose. Methylphenidate increased heart rate and subjective ratings; however, the subjective effects were primarily of a "dysphoric" nature, and significant effects were limited to increases in anxiety, depression, and anger on the Profile of Mood States; shaky/jittery ratings on a visual analog scale; and dysphoria on the lysergic acid diethylamide (LSD) scale of the Addiction Research Center Inventory. Methylphenidate did not increase cocaine craving nor ratings suggesting abuse potential (i.e., Morphine-Benzedrine Group or drug-liking scores, etc.). None of the drug effects observed in the human laboratory was of clinical concern, and no subject was precluded from continuing in the outpatient study. After outpatient treatment completion, 12 patients were brought back into a second double-blind human laboratory study in which three doses (15, 30, and 60 mg) of immediate-release methylphenidate were administered in an ascending series preceded and followed by placebo. Methylphenidate produced dose-related increases in heart rate, subjective ratings of shaky/jittery, and LSD/dysphoria without significantly altering cocaine craving or stimulant euphoria ratings. These results suggest that stimulant substitution-type approaches to the treatment of cocaine dependence are not necessarily contraindicated because of cardiovascular toxicity or medication abuse potential. However, they also suggest that the subjective effects of methylphenidate may not be positive enough for an adequate replacement approach.

Although sex researchers and therapists alike talk about treating "couples," there persists an assumption that "symptomatic" partners vary significantly from "asymptomatic" partners with respect to early background and personality variables. Indeed, these differences have been sometimes viewed as primary causal factors for the couple's presenting state of sexual discord. Data from a short-term intensive treatment program was analyzed to compare factors such as parental-familial background, sexual attitudes and knowledge, and marital histories for individuals diagnosed as symptomatic and their partners who received no specific sexual diagnosis. Results indicated few significant differences between these identified groups. There were also few differences between groups based upon items from a follow-up evaluation, suggesting that the prognostic value of these classifications may likewise be placed in question. In general, the couple's ongoing relationship (rather than individual characteristics) appears responsible for establishing satisfactory levels of sexual intimacy. Suggestions were made toward developing couple-oriented diagnostic and outcome categories.

An innovative model for organising social services in a community, the Imbrication Model, is contrasted with two traditional models, the Entrepreneurial and the Umbrella Agency. The structural characteristics and dynamics of the three models are illustrated with actual case histories. Imbrication Model calls for the interlocking of personnel from several agencies, with the purpose of redirecting the dysfunctional interagency rivalry prevalent in the traditional models. Imbrications at all organisational levels--Board of Directors, Administrators and Staff--facilitate adoption of the superordinate goal of providing clients with the best services available, regardless of which particular agency delivers the service. Few observers of the current social service scene would challenge the statement that needs for service are unlimited and resources limited. In the USA the imbalance between needs and resources persists despite a decade of massive governmental programmes intended to alleviate social ills. Recent substantial cutbacks in federal funds, moreover are not likely to improve the situation. The resource shortage involves more than a limitation of funds. Deliverers of service and competent programme administrators are also on critically short supply. These shortages are more often than not exacerbated by a chronic spirit of competition among agencies and programmes at the local level. Three organizational models for the delivery and administration of social services, two conventional and one of more recent date, are examined in this article. The innovative model, which has been named the Imbrication Model, explicitly calls for redirecting interagency rivalry and competition. Its ambitious goal is to integrate the efforts of those attempting to meet a community's social service needs.
