Abstract
The objective of this study was to examine body composition changes in adolescent girls initiating depot medroxyprogesterone acetate (DMPA), oral contraceptives, or no hormonal contraceptive method. At 6 months, DMPA resulted in significant increases in adiposity with concomitant decreases in lean body mass. Supplemental estrogen may lessen these DMPA effects.

Abstract
This study describes the accuracy of two types of bed-exit alarms to detect bed-exiting body movements: pressure-sensitive and a pressure-sensitive combined with infrared (IR) beam detectors (dual sensor system). We also evaluated the occurrence of nuisance alarms, or alarms that are activated when a participant does not attempt to get out of bed. Fourteen nursing home residents were directly observed for a total of 256 nights or 1636.5h; an average of 18.3+/-22.3 (+/-S.D.) nights/participant for an average of 6.4+/-1.2 h/night. After adjusting for body movements via repeated measures, Poisson regression modeling, the least squares adjusted means (LSM) show a marginally significant difference between the type of alarm groups on the number of true positives (NTP) (mean/S.E.M.=0.086/1.617) for pressure-sensitive versus dual sensor alarm (0.593/1.238; p=0.0599) indicating that the dual sensor alarm may have a higher NTP. While the dual sensor bed-exit alarm was more accurate than the pressure-sensitive alarm in identifying bed-exiting body movements and reducing the incidence of false alarms, false alarms were not eliminated altogether. Alarms are not a substitute for staff; adequate staff availability is still necessary when residents need or wish to exit bed.

Abstract
The Geriatric Institutional Assessment Profile (GIAP) is a self-administered survey of hospital nurses designed to assess a hospital's readiness to implement geriatric programs. The GIAP measures nurses' knowledge and attitudes toward older adults as well as the organizational attributes that support or constrain geriatric best practices. Test—retest reliability estimates of the GIAP were conducted with a sample of 166 direct care nurses in three urban, university-affiliated hospitals over a 3-week time period. Intraclass correlation coefficients of GIAP scales and subscales ranged between .82 and .92, demonstrating good to very good reliability. The GIAP is a reliable measure of organizational attributes of the hospital relevant to geriatric care.

Abstract
BACKGROUND The aim of this study was to assess the risk factors associated with mortality and morbidity following emergency or urgent colorectal surgery. MATERIALS AND METHODS All data regarding the 462 patients who underwent emergency colonic resection in our institution between November 2002 and December 2007 were prospectively entered into a computerized database. RESULTS The median age of patients was 73 (range 17-98) years. The most common indications for surgery were: 171 adenocarcinomas (37%), 129 complicated diverticulitis (28%), and 35 colonic ischemia (7.5%). Overall mortality and morbidity rates were 14% and 36%, respectively. In multivariate analysis, the only parameter significantly associated with postoperative mortality was blood loss >500 cm(3) (odds ratio (OR) = 3.33, 95% confidence interval (CI) 1.63-6.82, p = 0.001). There were three parameters which correlated with postoperative morbidity: ASA score > or =3 (OR = 2.9, 95% CI 1.9-4.5, p < 0.001), colonic ischemia (OR = 3.4, 95% CI 1.4-7.7, p = 0.006), and stoma creation (OR = 2.2, 95% CI 1.4-3.4, p = 0.0003). CONCLUSIONS The main risk factors for postoperative morbidity and mortality following emergency colorectal surgery are related to: (1) patients' ASA score, (2) colonic ischemia, and (3) perioperative bleeding. These variables should be considered in the elaboration of future scoring systems to predict outcome of emergency colorectal surgery.

Abstract
OBJECTIVE To examine hospitalisation rates and resource utilisation following initiation of risperidone long-acting therapy (RLAT) among US veterans with schizophrenia. METHODS Encounter data were analysed from the Ohio Veterans Affairs (VA) Healthcare System. Adult patients (schizophrenia or schizoaffective disorder) with ≥1 medical or hospital visits with a diagnosis code of 295.xx, continuous enrolment from January 2003 through January 2006, and ≥4 injections of RLAT were selected. Analyses compared psychiatric-related resource utilisation pre- and post-exposure to RLAT; each patient served as his/her own control. The pre-exposure and post-exposure periods defined were equal in duration (e.g., a 6-month post-exposure period was matched with a 6-month pre-exposure period). Descriptive and comparative analyses (paired t tests, McNemar's test) were performed. RESULTS Patients (n=106) were 51.9 years old (+/-10.2), male (93%), white (73%) and received on average 14 RLAT doses (+/-9.7; range, 4-47 injections) over 309 days (+/-196; range, 42-737 days). Most experienced a psychiatric-related hospitalisation prior to initiation; less than half experienced hospitalisation after initiation (75% vs. 42%; p<0.001). Relative to pre-initiation, fewer psychiatric-related hospitalisations (mean [SD] change, -0.8 [2.0]; p<0.001), shorter length of stay (-25 [63.6] days; p<0.001), fewer inpatient days/month (-3.1 [7.2] days) and one (2.8) additional outpatient visit/month (p<0.001) occurred post-initiation. LIMITATIONS The absence of a control group in this pre-/post comparison may have resulted in exposure to a regression to the mean effect. Also, this study evaluated only one cohort of patients in a VA healthcare setting. CONCLUSIONS VA patients with schizophrenia and schizoaffective disorder treated with RLAT experienced fewer hospitalisations and psychiatric-related inpatient days following RLAT initiation. Further studies utilising a control group and in non-VA populations are warranted.

Abstract
OBJECTIVE The aim of the study was to identify patient factors that correlate with a strong response to opioid pain medications in low back pain patients. DESIGN Prospective analysis. SETTING Tertiary Institutional Spine Care Center. PATIENTS, PARTICIPANTS All patients visiting a tertiary referral spine center with primary diagnosis of low back pain (n = 486) and minimum duration of 6 months. INTERVENTIONS Opioid medication. MAIN OUTCOME MEASURES Analysis factors included visual analog pain scale (VAS), symptom relief scores, and results on 36-item Short Form Health Survey (SF-36). A longitudinal descriptive analysis and a multivariable logistic regression were performed on the results of the VAS and SF-36 scores. RESULTS The average age of opioid and nonopioid treated patients was 62 years versus 64 years, (p = 0.13) and gender distributions at 53 percent versus 50 percent female (p = 0.43). SF-36 scores were statistically significant and associated with the opioid categorization. For every unit increase in symptom relief score, the likelihood of opioid use is doubled (OR = 2.1, 95 percent CI = 1.5-2.8, p < 0.001); and increased by 25 percent with each 10-point decrease in the social functioning quality of life score (OR = 0.98, 95 percent CI = 0.96-0.99, p = 0.006). CONCLUSIONS Social quality of life and symptom relief measurements comprise the optimal set of independent factors that correlate most strongly with a response to opioid use in low back pain patients.

Abstract
BACKGROUND Anastomotic dehiscence is the most severe surgical complication after large bowel resection. This study was designed to assess the incidence, to observe the consequences, and to identify the risk factors associated with anastomotic leakage after colorectal surgery. MATERIALS AND METHODS All procedures involving anastomoses of the colon or the rectum, which were performed between November 2002 and February 2006 in a single institution, were prospectively entered into a computerized database. RESULTS One thousand eighteen colorectal resections and 811 anastomoses were performed over this 40-month period. The most frequent procedures were sigmoid (276) and right colectomies (217). The overall anastomotic leak rate was 3.8%. The mortality rate associated with anastomotic leak was 12.9%. In univariate analysis, the following parameters were associated with an increased risk for anastomotic dehiscence: (1) ASA score >or= 3 (p = 0.004), (2) prolonged (>3 h) operative time (p = 0.02), (3) rectal location of the disease (p < 0.001), (4) and a body mass index > 25 (p = 0.04). In multivariate analysis, ASA score >or= 3 (OR = 2.5; 95% CI 1.5-4.3, p < 0.001), operative time > 3 h [OR = 3.0; 95% CI 1.1-8.0, p = 0.02), and rectal location of the disease (OR = 3.75; 95% CI 1.5-9.0 (vs left colon), p = 0.003; OR = 7.69; 95% CI 2.2-27.3 (vs right colon), p = 0.001] were factors significantly associated with a higher risk of anastomotic dehiscence. CONCLUSIONS Three risk factors for anastomotic leak have been identified, one is patient-related (ASA score), one is disease-related (rectal location), the third being surgery-related (prolonged operative time). These factors should be considered in perioperative decision-making regarding defunctioning stoma formation.

Abstract
Liver transplantation (LT) as a treatment for Hepatocellular Carcinoma (HCC) provides excellent outcomes if restricted to patients who meet the Milan criteria (MC). The aim of this study was to evaluate the influence of ethnicity on eligibility for LT based on the MC. This is a retrospective cohort study of patients diagnosed with HCC at our institution between January 2000 and September 2005. We identified 169 patients, of whom 135 were male (80%), 108 were Caucasian (64%), 29% were African American (AA) and 7% were of other ethnicity. Eighty two patients (49%) met the MC at diagnosis. Age, gender, severity of liver disease or insurance status was not predictive of meeting MC at diagnosis. Ethnicity was the only significant predictor for failure to meet MC. Significantly fewer Caucasians exceeded the MC compared to AA (44 vs. 71%; P = 0.0015). Conclusion AA are more likely to present with HCC that exceeds the MC.

Abstract
Seat height that is too high (> 120% of lower leg length [LLL]) or too low (< 80% of LLL) can impede safe transfer and result in falls. This study examines the difference between LLL of frail nursing home residents and the height of their toilets and beds in the lowest position, compares the patient or environmental characteristics of those able to transfer from the bed or toilet to those who cannot, and determines the relationship of patient or environmental characteristics to bed-related falls. A retrospective observational design using secondary data from 263 nursing home residents finds that bed height of three fourths of participants was greater than 140% of LLL, whereas toilet height of more than half was 100% to 120% of LLL. Increased fall risk is associated with increased age, shorter length of stay, normal lower extremity range of motion, less cognitive impairment, more behavioral symptoms, and no complaints of pain during exam.

Abstract
OBJECTIVE To determine whether bone mineral density (BMD) is lower in hormonal-contraceptive users than in an untreated comparison group. DESIGN Observational, prospective cohort; 24-month duration. SETTING Adolescent clinics in a metropolitan Midwestern setting. PATIENT(S) Four hundred thirty-three postmenarcheal girls, 12-18 years of age, who were on depot medroxyprogesterone acetate (DMPA; n = 58), were on oral contraceptives (OCs; n = 187), or were untreated (n = 188). INTERVENTION(S) Depot medroxyprogesterone acetate and OCs containing 100 microg of levonorgestrel and 20 microg of ethinyl E(2). MAIN OUTCOME MEASURE(S) Measurements of BMD at spine and femoral neck were obtained by using dual x-ray absorptiometry at baseline and 6-month intervals. RESULT(S) Over 24 months, mean percentage change in spine BMD was as follows: DMPA, -1.5%; OC, +4.2%; and untreated, +6.3%. Mean percentage change in femoral neck BMD was as follows: DMPA, -5.2%; OC, +3.0%; and untreated, +3.8%. Statistical significance was found between the DMPA group and the other two groups. In the DMPA group, mean percentage change in spine BMD over the first 12 months was -1.4%; the rate of change slowed to -0.1% over the second 12 months. No bone density loss reached the level of osteopenia. CONCLUSION(S) Adolescent girls receiving DMPA had significant loss in BMD, compared with bone gain in the OC and untreated group. However, the clinical significance of this finding is mitigated by slowed loss after the 1st year of DMPA use and general maintenance of bone density values within the normal range in the DMPA group.

Abstract
UNLABELLED Long-term allograft and patient survival following liver transplantation continues to improve with the development of new surgical techniques and immunosuppressive agents. Complications such as primary nonfunction (PNF) have not been well characterized in terms of long-term allograft and patient survival. The aim of this study was to determine the incidence of PNF in liver transplant recipients and patient and graft survival, in addition to identifying temporal trends in these parameters. METHOD Data were obtained from the United Network for Organ Sharing/Organ Procurement and Transplant Network for all adults (>18 years old) who received a deceased donor liver transplant between January 1990 and December 2004. RESULTS Of the 58,576 liver transplant recipients, 2061 had PNF, an overall incidence of 3.5%. There was a 30% annual increase in the incidence of PNF between 1990 and 2000; the incidence of PNF peaked at 7%, and then decreased by 20% annually thereafter. No differences in donor and perioperative variables were identified to account for this variation. One-, 3-, and 5-year patient and graft survival for patients with PNF who underwent retransplant were significantly lower than those with primary liver transplant. In conclusion, there has been decreased incidence of PNF among liver transplant recipients in the last decade.

Abstract
This study tested effectiveness of music therapy in improving health-related outcomes of cardiac rehabilitation patients. Using a randomized, controlled trial with follow-up, the study was conducted in an outpatient cardiac rehabilitation program in Ohio. Sixty-eight of 103 recruited patients, 30 to 80 years of age, completed the protocol through posttreatment. Physiological and psychological outcomes were measured. Cardiac rehabilitation patients were randomly assigned to cardiac rehabilitation only or to music therapy plus cardiac rehabilitation. Music therapy included musical experiences, counseling, and Music-Assisted Relaxation and Imagery. The null hypothesis of no differences in health-related outcomes between cardiac rehabilitation patients who experienced cardiac rehabilitation with and without music therapy was rejected due to changes in systolic blood pressure pre to post-treatment. Interpretation of changes at 4 months posttreatment in anxiety, general health, and social functioning are limited, due to small sample sizes at follow-up. Pre to post-music therapy session improvements were also reported. Findings suggest that some health-related outcomes may be affected positively by participation in music therapy in addition to cardiac rehabilitation. Attrition contributed to limitations in statistical power.

Abstract
BACKGROUND This observational study aimed to examine the prevalence of activities of daily living, as well as the impact of leisure time activities, on bone mineral density in urban adolescent girls. METHODS Patients completed a 23-item physical activity questionnaire at baseline, recording time spent in various activities in the previous 7 days. In addition to leisure time activities, activities of daily life were also considered. Activities were characterized and scored by metabolic intensity (METPA) and mechanical strain on bone (MECHPA). The METPA score for each activity is the product of the metabolic intensity of the activity and the time spent in the activity. The MECHPA score estimates the mechanical strain on bone from ground reaction forces. The logged scores were divided into quartiles with the lowest quartile as the reference group. RESULTS Four hundred fifty-five females (ages 12-18 years) completed the survey (62% black and 38% non-black). The log of the overall METPA score was a significant predictor of bone mineral density (i.e. higher METPA score predicted a higher bone mineral density, P = 0.03). A MECHPA score in the highest quartile was associated with a higher bone mineral density (P < 0.05) when compared to the other MECHPA quartiles. CONCLUSIONS In this population of urban adolescent girls, activities of daily living were reported with a higher frequency than sports activities. Results indicated a positive association between the time spent in metabolically intense activities and bone mineral density. There also appears to be a threshold effect for the relationship between activities with the highest mechanical strain and bone mineral density.

Abstract
OBJECTIVE To examine weight changes in a large cohort of obese and nonobese adolescent girls initiating depot medroxyprogesterone acetate (DMPA), an oral contraceptive (OC), or no hormonal contraceptive method (control). DESIGN, SETTING, AND PARTICIPANTS Prospective study of 450 adolescent girls, aged 12 to 18 years, who attended 4 urban health clinics and selected DMPA, OC, or control. Data collection occurred at baseline and at 6, 12, and 18 months; consisted of structured interview and measurement of height and weight; and occurred from April 19, 2000, through September 26, 2003. MAIN OUTCOME MEASURE Weight was examined as mean change over 18 months and actual weight at each study visit. On the basis of preliminary analyses, we stratified the sample according to baseline obesity status (nonobese, body mass index [calculated as weight in kilograms divided by the square of height in meters] < 30; obese, body mass index > or =30). RESULTS Adolescent girls who were obese at initiation of DMPA gained significantly more weight than did obese girls starting OC or control (P<.001 for both). At 18 months, mean weight gain was 9.4, 0.2, and 3.1 kg for obese girls receiving DMPA, receiving OC, and control, respectively. Weight gain in obese girls receiving DMPA was also greater than weight gain in all nonobese categories (4.0 kg, DMPA; 2.8 kg, OC; 3.5 kg, control; P<.001). A significant interaction (P = .006) between length of time receiving DMPA and weight gain was evident for obese subjects. CONCLUSIONS Over 18 months, DMPA use was associated with increasing rates of weight gain in obese subjects. The potential contribution to severe obesity in this population is concerning.

Abstract
INTRODUCTION Control of blood pressure can be a problem for intracranial procedures. To investigate the relationship between hemodynamic variables and endogenous vasoactive substances, we studied patients undergoing resection of arteriovenous malformations (AVMs). METHODS This was a nonrandomized, prospective study of six patients who had resection of an intracranial AVM and six patients who had clipping of an intracranial aneurysm (ICA) that had not bled. Operative and postoperative blood pressure was controlled with sodium nitroprusside. Heart rate (HR), mean arterial pressure, pulmonary capillary wedge pressure, and cardiac index (CI) were measured after induction of anesthesia; before, during, and after hypotensive anesthesia; immediately postoperatively; and at 12, 24, and 36 hours postoperatively. Blood samples were drawn simultaneously in the AVM group to measure levels of norepinephrine, epinephrine, renin, aldosterone, vasopressin, angiotensin I, and angiotensin II and correlated with significant hemodynamic changes. RESULTS HR and CI increased significantly among patients with AVMs compared with patients with ICAs (p<0.001 and p=0.05, respectively). HR was significantly correlated with renin (r=0.60), norepinephrine (r=1.00), and vasopressin (r=0.66). CI was significantly correlated with epinephrine (r=1.00), renin (r=0.77), angiotensin II (r=0.71), and vasopressin (r=0.82). Patients with AVMs had a hyperdynamic state characterized by increases in HR and CI. These increases were accompanied by increased renin, norepinephrine, vasopressin, epinephrine, and angiotensin II serum concentrates. CONCLUSIONS There were no significant differences in blood pressure changes between patients who had resection for AVM and those who had clipping of ICA, probably due to the use of sodium nitroprusside in the AVM group. Patients with AVMs had a hyperdynamic state with increases in epinephrine, norepinephrine, angiotensin II, plasma renin activity, and vasopressin. Whether this hyperdynamic state is caused by the resection of the AVM or the use of sodium nitroprusside (SNP) cannot be concluded. Blockage of these mediators preoperatively may help control blood pressure without sodium nitroprusside.

Abstract
BACKGROUND We are not aware of any previous studies in which independent measurements of function with validated outcome questionnaires such as the Knee Injury and Osteoarthritis Outcome Score and the International Knee Documentation Committee score were evaluated five years after reconstruction of the anterior cruciate ligament. We hypothesized that patient demographics, mechanism of injury, and intra-articular injuries and their treatment are factors associated with function five years after reconstruction of the anterior cruciate ligament. METHODS A consecutive series of unilateral, arthroscopically assisted primary reconstructions of the anterior cruciate ligament performed by one surgeon using a patellar tendon graft was evaluated. Data on patient demographics, injury variables, and intra-articular lesions noted at the time of surgery were collected prospectively. Multivariable regression analysis was used to identify independent predictors of outcomes as measured with five questionnaires. RESULTS Sixty-nine percent (217) of 314 knees with a reconstruction of the anterior cruciate ligament were followed for an average of 5.4 years. The average age at the time of the operation was twenty-seven years. Independent predictors of a worse outcome, which was measured with the overall Knee Injury and Osteoarthritis Outcome Score, the International Knee Documentation Committee score, the Lysholm score, and the Western Ontario and McMaster Universities Osteoarthritis Index score, included the patient's recollection of hearing or feeling a pop at the time of the injury, a weight gain of >15 lb (6.8 kg), and no change in educational level since the surgery. There was a lack of association between the outcome and either the occurrence or the form of treatment of a meniscal tear or chondromalacia of the articular cartilage. CONCLUSIONS To our knowledge, we performed the first prospective cohort study to evaluate the prognosis following reconstruction of the anterior cruciate ligament by identifying significant associations between multiple variables and clinical outcomes as measured with validated questionnaires. The clinician can counsel patients about the intermediate-term functional outcomes of reconstructions of the anterior cruciate ligament on the basis of these findings. Suggestions regarding weight control and future education may improve intermediate-term outcomes.

Abstract
STUDY OBJECTIVE To examine the relationship between biochemical markers of bone metabolism and hormonal contraception in adolescents. DESIGN A prospective, observational design. SETTING The study was conducted in four adolescent health clinics in a large metropolitan area. PARTICIPANTS The study population comprised healthy, postmenarcheal adolescent girls aged 12-18 initiating either medroxyprogesterone acetate (n=53) or an oral contraceptive (OC) containing 20 mug ethinyl estradiol/100 mug levonorgestrel (n=165) and those using no hormonal contraception (n=152). INTERVENTIONS None. MAIN OUTCOME MEASURES Serum bone specific alkaline phosphatase (BSAP), urinary deoxypyridinoline (DPD), and bone mineral density (BMD) at baseline and 12 months. RESULTS At 12 month follow-up, serum BSAP levels were significantly higher (P < 0.05) in the control group (40.4 U/L +/- 1.03 SE), than in the DMPA group (35.2 U/L +/- 1.05 SE) and the OC group (35.5 U/L +/- 1.03 SE). There was a trend in urinary DPD levels to be higher (P=0.08) in the control group (9.9 nmol/mmol Cr +/- 1.03 SE) than in the DMPA group (9.1 +/- 1.05 SE) and the OC group (8.9 +/- 1.03 SE). No relationship was found between the biochemical markers and BMD at the lumbar spine or the femoral neck. CONCLUSIONS Over 12 months, there was evidence of increased bone formation and resorption in the control group when compared to that in the DMPA and OC groups. This finding may indicate a suppression of bone metabolism in girls using DMPA or an OC containing 20 mug ethinyl estradiol/100 mug levonorgestrel.

Abstract
BACKGROUND Numerous studies suggest that the dihydropyridine calcium antagonists (DCAs) and nondihydropyridine calcium antagonists (NDCAs) have differential antiproteinuric effects. Proteinuria reduction is a correlate of the progression of renal disease. In an earlier systematic review, calcium antagonists were shown as effective antihypertensive drugs, but there was uncertainty about their renal benefits in patients with proteinuria and renal insufficiency. METHODS A systematic review was conducted to assess the differential effects of DCAs and NDCAs on proteinuria in hypertensive adults with proteinuria, with or without diabetes, and to determine whether these differential effects translate into altered progression of nephropathy. Studies included in the review had to be randomized clinical trials with at least 6 months of treatment, include a DCA or NDCA treatment arm, have one or more renal end points, and have been initiated after 1986. Summary data were extracted from 28 studies entered into two identical but separate databases, which were compared and evaluated by independent reviewers. The effects of each drug class on blood pressure (N= 1338) and proteinuria (N= 510) were assessed. RESULTS After adjusting for sample size, study length, and baseline value, there were no statistically significant differences in the ability of either class of calcium antagonist to decrease blood pressure. The mean change in proteinuria was +2% for DCAs and -30% for NDCAs (95% CI, 10% to 54%, P= 0.01). Consistently greater reductions in proteinuria were associated with the use of NDCAs compared with DCAs, despite no significant differences in blood pressure reduction or presence of diabetes. CONCLUSION This analysis supports (1) similar efficacy between subclasses of calcium antagonists to lower blood pressure, and (2) greater reductions in proteinuria by NDCAs compared to DCAs in the presence or absence of diabetes. Based on these findings, NDCAs, alone or in combination with an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB), are suggested as preferred agents to lower blood pressure in hypertensive patients with nephropathy associated with proteinuria.

Abstract
Cryotherapy has been shown to decrease intraarticular temperature in all regions of the knee after arthroscopy. The purpose of our study was to determine if similar declines in intraarticular temperature were seen with the use of cryotherapy after anterior cruciate ligament reconstruction, a procedure which, unlike simple arthroscopy, produces postoperative hemarthrosis. Sixteen patients had intraarticular temperatures measured for 2 hours after anterior cruciate ligament reconstruction with cryotherapy instituted for only 1 of the 2 hours (eight patients for the first hour and eight patients for the second hour). Significant declines were seen in the suprapatellar pouch after either hour (-2.7 degrees C in Group 1, -2.7 degrees C in Group 2) but not in the lateral gutter. The difference between cryotherapy versus no cryotherapy in the first hour in the suprapatellar pouch was 6.0 degrees C, a clinically meaningful temperature difference. We hypothesize the swelling and hemarthrosis was more pronounced in the lateral gutter because of its dependent position and therefore blunted the effect of cryotherapy seen in the lateral gutter. Cooling of the intraarticular temperature should be considered in the clinical benefits of cryotherapy.

Abstract
OBJECTIVES A growing body of literature suggests that certain atypical antipsychotics, especially olanzapine and clozapine, may induce glucoregulatory dysfunction. We assessed the differences in risk of developing diabetes mellitus during treatment with olanzapine and risperidone by using patients treated with haloperidol and fluphenazine as control subjects in whom we would not expect to see an increased risk. METHODS We conducted a retrospective analysis of the Veteran's Integrated Service Network 10 Veterans Affairs (VA) database. Data for patients receiving olanzapine, risperidone, haloperidol, or fluphenazine from January 1, 1997-December 31, 2000, were included. Diabetes was defined as any health system encounter associated with the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis for diabetes (250.xx) or prescription for a hypoglycemic agent. Data of patients with markers for diabetes within 1 year before their index date, female patients, racial groups other than Caucasian or African-American, and patients receiving clozapine were not analyzed. We performed a Cox regression, with antipsychotic therapy as a time-dependent covariate. Other covariates considered for inclusion in the final model were number of days supply of antipsychotic drug, age, race, psychiatric diagnoses, substance abuse, lithium, valproic acid, and other typical or atypical antipsychotic agents. RESULTS Data for 5837 patients were analyzed. Overall rate of developing diabetes in the study population was 6.3% (368 of 5837 patients). Olanzapine therapy was associated with a significantly higher risk of development of diabetes compared with risperidone (hazard ratio [HR] 1.37, 95% confidence interval 1.06-1.76, p=0.016) while controlling for race, age, diagnosis, substance abuse, lithium, valproic acid, and other atypical antipsychotic agents. No differences in the rate of developing diabetes were detected between fluphenazine and risperidone (HR 1.11, p=0.69), or haloperidol and risperidone (HR 0.89, p=0.41). CONCLUSIONS Olanzapine was associated with a 37% (HR 1.37) increased risk of development of diabetes compared with risperidone in a VA population, even after adjusting for other factors associated with the development of diabetes and temporal exposure to study drug. Because of limitations associated with database research, prospective studies should be conducted to corroborate these findings.

Abstract
OBJECTIVE To compare pathology in knees with an anterior cruciate ligament (ACL) injury as a result of a jumping mechanism with knees injured from a nonjumping mechanism. DESIGN This was a prospective study of 263 consecutive patients with a complete ACL tear and no subsequent giving way episodes nor reinjuries prior to undergoing an ACL reconstruction. The patients were placed into one of two groups: those with knees injured as a result of a jumping injury, and those with knees injured as a result of a nonjumping injury. SETTING This study was performed at the Cleveland Clinic Foundation, Cleveland, Ohio. PATIENTS Anterior cruciate ligament-deficient knees undergoing ACL reconstruction. Two hundred thirty-eight (91%) of the patients were injured while participating in sports. MAIN OUTCOME MEASURED Intra-articular pathology documented prospectively at the time of arthroscopy. RESULTS Knees injured as a result of a jumping mechanism had a higher incidence of medial (p = 0.05) and lateral (p = 0.03) meniscal tears and a lower incidence of medial collateral ligament injuries (p = 0.05). No difference in arthroscopic articular cartilage injuries was seen between the two groups. CONCLUSIONS We believe that identifying jumping as a mechanism of ACL tears is important, since a jumping mechanism is associated with a significantly increased meniscus tear rate and may predispose this population to future degenerative changes.

Abstract
INTRODUCTION Hyaluronate carboxymethylcellulose-based bioresorbable membrane (Seprafilm ) has been used as a method of postoperative adhesion prevention. However, its short-term effect on colorectal cancer recurrence remains unknown. METHODS A retrospective chart review was undertaken of patients with colorectal cancer operated on with curative intent from 1996 to 1999. All patients who received Seprafilm during surgery were assigned to the Seprafilm group, whereas all patients who did not were placed in a control group. Tumor recurrence was defined as persistently elevated carcinoembryonic antigen levels, pathologic confirmation of endoscopic findings, or radiographically documented lesions in the liver, lung, or pelvis. RESULTS There were 63 patients in the Seprafilm group and 93 in the control group. The two groups were well matched according to all standard clinical and pathologic characteristics. Adjuvant chemoradiotherapy was administered to 23 patients (36.5 percent) in the Seprafilm group and to 44 (47.3 percent) in the control group ( P= 0.24). At a mean follow-up of 11.4 +/- 7.3 months in the Seprafilm group and 14.2 +/- 11.9 months in the control group, there were 6 (9.5 percent) and 15 (16.1 percent) recurrences, respectively ( P= 0.33). The 1- and 2-year disease-free survival rates were 88 and 85 percent, respectively, in the Seprafilm group and 85 and 72 percent, respectively, in the control group (log-rank test, P= 0.44). CONCLUSION Seprafilm did not adversely affect the short-term recurrence rate after curative resection of colorectal cancer. In addition, it did not appear to compromise the short-term oncologic outcome. However, with a short follow-up and a small denominator, a definitive conclusion cannot be drawn. This study does intimate that larger, longer-term, prospective, randomized studies may be safely conducted.
