Effects of triple antiplatelet therapy (aspirin, clopidogrel, and cilostazol) on platelet aggregation and P-selectin expression in patients undergoing coronary artery stent implantation.

The purpose of this study was to determine the effect of the addition of cilostazol to aspirin plus clopidogrel on platelet aggregation after intracoronary stent implantation. Twenty patients who underwent coronary stent placement were randomly assigned to therapy with aspirin plus clopidogrel (dual-therapy group, n = 10) or aspirin plus clopidogrel plus cilostazol (triple-therapy group, n = 10). A loading dose of clopidogrel (300 mg) and cilostazol (200 mg) was administered immediately after stent placement, and clopidogrel (75 mg/day) and cilostazol (100 mg twice daily) were given for 1 month. Platelet aggregation in response to adenosine diphosphate (ADP; 5 and 20 micromol/L) or collagen and P-selectin (CD-62P) expression was assayed at baseline, 2 hours, 24 hours, 1 week, and 1 month after stent placement. Inhibition of ADP-induced platelet aggregation was significantly higher in patients receiving triple therapy than those receiving dual therapy from 24 hours after stent placement, and inhibition of collagen-induced platelet aggregation was significantly higher in the triple-therapy group beginning 1 week after stent placement. P-Selectin expression was significantly lower in the triple-therapy than dual-therapy group at 1 week and 30 days. In conclusion, compared with dual antiplatelet therapy, triple therapy after coronary stent placement resulted in more potent inhibition of platelet aggregation induced by ADP and collagen. These findings suggest that triple therapy may be used clinically to prevent thrombotic complications after coronary stent placement.
RITZ-5: randomized intravenous TeZosentan (an endothelin-A/B antagonist) for the treatment of pulmonary edema: a prospective, multicenter, double-blind, placebo-controlled study.

The objective of this study was to evaluate the addition of intravenous (IV) tezosentan to standard therapy for patients with pulmonary edema.



Tezosentan is an IV nonselective endothelin (ET)-1 antagonist that yields favorable hemodynamic effects in patients with acute congestive heart failure (CHF).



Pulmonary edema was defined as acute CHF leading to respiratory failure, as evidenced by an oxygen saturation (SO(2)) <90% by pulse oxymeter despite oxygen treatment. All patients received oxygen 8 l/min through a face mask, 3 mg of IV morphine, 80 mg of furosemide, and 1 to 3 mg/h continuous drip isosorbide-dinitrate according to their blood pressure level and were randomized to receive a placebo or tezosentan (50 or 100 mg/h) for up to 24 h.



Eighty-four patients were randomized. The primary end point, the change in SO(2) from baseline to 1 h, was 9.1 +/- 6.3% in the placebo arm versus 7.6 +/- 10% in the tezosentan group (p = NS). The incidence of death, recurrent pulmonary edema, mechanical ventilation, and myocardial infarction during the first 24 h of treatment was 19% in both groups. Reduced baseline SO(2), lower echocardiographic ejection fraction, high baseline mean arterial blood pressure (MAP), and inappropriate vasodilation (MAP reduction at 30 min of <5% or >30%) correlated with worse outcomes. A post-hoc analysis revealed that the outcome of patients who received only 50 mg/h tezosentan was better than patients in the placebo group whereas patients receiving 100 mg/h had the worst outcomes.



In the present study, tezosentan (an ET-1 antagonist) did not affect the outcome of pulmonary edema, possibly because of the high dose used.
Psychometric properties of the SF-12 (Hebrew version) in a primary care population in Israel.

To evaluate the psychometric properties of the 12-item Medical Outcomes Study (MOS) Short-Form Health Status Survey (SF-12) (Hebrew version) in a large primary care patient sample in Israel.



The sample comprised 3631 adult primary care patients who were screened for depression in a longitudinal design.



SF-12 yielding two scores: the Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12). For comparison, the Center for Epidemiological Studies - Depression scale (CES-D), two subscales from the 90-item Hopkins Symptom Scale (SCL-90), Quality of Life Depression Scale (QLDS), World Health Organization Quality of Life Measure - Bref (WHOQoL-Bref), and interviewer-administered Composite International Diagnostic Interview (CIDI) were also administered.



Score distribution was satisfactory, the amount of missing data was minimal and item-to-item correlations were satisfactory. Floor and ceiling effects were minimal in items with more than three response options. A confirmatory factor analysis supported the two-dimensional model of health. Test-retest reliability was good for both summary scales in a nondepressed population and for PCS-12 in the depressed population, but only moderate for MCS-12 in the depressed population. In regard to convergent validity, MCS-12 correlated negatively and significantly with the CES-D, QLDS, and two SCL-90 anxiety subscales, and positively and significantly with four WHOQoL-Bref domains. PCS-12 correlated positively and significantly with the WHOQoL-Bref physical domain. Discriminative validity was established in that both PCS-12 and MCS-12 showed meaningful effect sizes between groups with various degrees of physical and mental health problems. Sensitivity to change was established in that both PCS-12 and MCS-12 change scores were significantly different in subjects who had been depressed but were no longer so, as compared with those who were still depressed at follow-up.



The SF-12 (Hebrew version) is a reliable and valid measure, particularly in a nondepressed population.
Lateral prefrontal cortex activity during cognitive control of emotion predicts response to social stress in schizophrenia

LPFC dysfunction is a well-established neural impairment in schizophrenia and is associated with worse symptoms. However, how LPFC activation influences symptoms is unclear. Previous findings in healthy individuals demonstrate that lateral prefrontal cortex (LPFC) activation during cognitive control of emotional information predicts mood and behavior in response to interpersonal conflict, thus impairments in these processes may contribute to symptom exacerbation in schizophrenia. We investigated whether schizophrenia participants show LPFC deficits during cognitive control of emotional information, and whether these LPFC deficits prospectively predict changes in mood and symptoms following real-world interpersonal conflict. During fMRI, 23 individuals with schizophrenia or schizoaffective disorder and 24 healthy controls completed the Multi-Source Interference Task superimposed on neutral and negative pictures. Afterwards, schizophrenia participants completed a 21-day online daily-diary in which they rated the extent to which they experienced mood and schizophrenia-spectrum symptoms, as well as the occurrence and response to interpersonal conflict. Schizophrenia participants had lower dorsal LPFC activity (BA9) during cognitive control of task-irrelevant negative emotional information. Within schizophrenia participants, DLPFC activity during cognitive control of emotional information predicted changes in positive and negative mood on days following highly distressing interpersonal conflicts. Results have implications for understanding the specific role of LPFC in response to social stress in schizophrenia, and suggest that treatments targeting LPFC-mediated cognitive control of emotion could promote adaptive response to social stress in schizophrenia.
Phase II study of 3-hour infusion of high dose paclitaxel in refractory and relapsed aggressive non-Hodgkin ' s lymphomas

Haematologica vol. 85(5):May 2000 Haematologica 2000; 85:502-507 original paper Malignant Lymphomas  The first clinical studies of paclitaxel as a single agent for the treatment of relapsed or refractory low or intermediate grade non-Hodgkin's lymphomas (NHL) yielded controversial results regarding the response rates observed, mainly related to the dose and schedule of administration used. To obtain additional data concerning the efficacy and toxicity of paclitaxel in intermediate and high grade NHL we initiated a phase II study using a 3-hour infusion of high doses of paclitaxel.  The eligibility criteria included patients with relapsed or refractory aggressive NHL, a performance status ≤ 2 (WHO index), a platelet count ≥ 100,000/μL, a neutrophil count ≥2,000/μL, measurable disease, and adequate hepatic function. Patients were excluded if they were infected with HIV, had a left ventricular ejection fraction < 50%, or prior peripheral neuropathy. Paclitaxel was administered as a 3-hour infusion at a dose of 250 mg/m2 every 3 weeks for a maximum of 6 courses.  Of 45 eligible patients, 42 received a total 73 courses of paclitaxel. Forty patients were assessable for response (89%), and 42 for toxicity (93%). Six patients (15%) achieved a partial (n = 4) or a complete remission (n = 2). Responses were observed in intermediate grade (n = 4) as well as in high grade lymphoma (n = 2). The main factor influencing the response to paclitaxel was the median duration of response to previous chemotherapy regimens which was 3 times longer in patients who responded to paclitaxel (16.3 months) than in patients who did not respond to paclitaxel (5.2 months) (p < 0.05). The most common serious side effects were related to the hematologic toxicity of paclitaxel, and included grade IV granulocytopenia in 20 cases (48%), grade III/IV thrombocytopenia in 14 cases (33%) and grade III-IV anemia in 13 cases
Long-term prospective assessment of shoulder function after breast reconstruction involving a latissimus dorsi muscle flap transfer and postoperative radiotherapy.

Several investigators have evaluated the impaired function of the shoulder after removal of the latissimus dorsi muscle for breast reconstruction. However, a few investigators have studied whether including radiotherapy has a negative effect on functional recovery of the shoulder by a long-term follow-up after surgery. In this study, we compared objective measurements of shoulder function preoperatively and postoperatively for 3 years after latissimus dorsi muscle (LDM) flap transfer and postoperative radiotherapy (PRT).



Eighteen patients who underwent unilateral transfer of a pedicled LDM flap and PRT within 2 months of breast-conserving surgery were enrolled in this study. Range of motion (ROM) and muscle strength in exhaustive shoulder movements were measured before surgery, and at 3 and 6 months, and 1 and 3 years.



The results of ROM measurements at 3months postsurgery showed significant decreases in both flexion and abduction by 7.1 and 9.2 % and at 3 years postsurgery by 4.7 and 5.7 %. The muscle strength measurements at 3 months postsurgery showed statistically significant decreases both in adduction and in the 2nd medial rotation by 30.7 and 25.9 % and at 3 years postsurgery by 36.4 and 20.4 %. A significant improvement in these impairments was not observed for 3 years after surgery compared with that at 3 months after surgery.



A combination of the LDM flap procedure and PRT could be associated with a higher incidence of tissue adhesions in both flexion and abduction and muscle deficit both in adduction and in the 2nd medial rotation.
Improving outcomes for diverse populations disproportionately affected by diabetes: final results of Project IMPACT: Diabetes.

To improve key indicators of diabetes care by expanding a proven community-based model of care throughout high-risk areas in the United States.



Observational, multisite, pre-post comparison study.



Federally qualified health centers, free clinics, employer worksites, community pharmacies, departments of health, physician offices, and other care facilities in 25 communities in 17 states from June 2011 through January 2013.



1,836 patients disproportionately affected by diabetes representing diverse ethnicities, insurance statuses, and social and economic backgrounds.



Pharmacists were integrated into local, interdisciplinary diabetes care teams and provided customized diabetes education and medication consultations to patients.



Clinical measures included glycosylated hemoglobin (A1C), body mass index, systolic and diastolic blood pressures, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, and total cholesterol. Process measures included smoking status, eye examination status, foot examination status, and influenza vaccine status.



Pharmacist patient care services for those underserved or disproportionately affected by diabetes resulted in a statistically significant and clinically relevant decrease in mean A1C levels (-0.8%). Other outcome indicators were below target levels at baseline and decreased significantly but not by clinically relevant amounts (LDL-C, -7.1 mg/dL; triglycerides, -23.7 mg/dL, and total cholesterol, -8.8 mg/dL). The mean increase in HDL-C (+0.6 mg/dL) was not statistically significant or clinically relevant. Among evaluable patients who were not at target for process measures at baseline, 51.7% of 453 patients received eye examinations, 72.0% of 271 patients received foot examinations, 41.7% of 307 patients received influenza vaccinations, and 9.3% patients of 270 quit smoking during the project. Of the communities involved in the study, 92% intend to sustain pharmacists' services.



Project



Diabetes results show significant improvement in patients' clinical outcomes and demonstrate that all patients, even those with tremendous barriers to appropriate diabetes care, benefit from patient-centered, interdisciplinary health care teams that include pharmacists.
Phase I trial of interleukin-2 after unmodified HLA-matched sibling bone marrow transplantation for children with acute leukemia.

Allogeneic bone marrow transplantation (BMT) for advanced acute leukemia is associated with a high risk of relapse. It is postulated that interleukin-2 (IL-2) administered after BMT might induce or amplify a graft-versus-leukemia effect and thereby reduce the relapse rate. To identify an IL-2 regimen for testing this hypothesis, a phase I trial of IL-2 (Roche) was performed in children in complete remission (CR) without active graft-versus-host disease (GVHD) off immunosuppressive agents after unmodified allogeneic matched-sibling BMT for acute leukemia beyond first remission. Beginning a median of 68 days after BMT, 17 patients received escalating doses of induction IL-2 (0.9, 3.0, or 6.0 x 10(6) IU/m2/d representing levels I, II, and III) for 5 days by continuous intravenous infusion (CIV). After 6 days of rest, they received maintenance IL-2 (0.9 x 10(6) IU/m2/d) for 10 days by CIV infusion. Levels I and II were well-tolerated, but, of 6 patients at level III, 1 developed pulmonary infiltrates, 1 developed hypotension (both resolved), and 1 died of bacterial sepsis and acute respiratory distress syndrome. Grade II acute GVHD developed in 1 patient at level I and 1 at level III. The maximum tolerated dose of induction IL-2 was level II. IL-2 induced lymphocytosis, with an increase in CD56+ and CD8+ cells. Ten patients remain in CR at 5+ to 67+ months. Thus, a regimen of IL-2 has been identified that did not induce a high incidence of acute GVHD when administered to children after unmodified allogeneic BMT. Its clinical activity will be assessed in a phase II trial.
Cerebrospinal fluid monoamine metabolite concentrations as intermediate phenotypes between glutamate-related genes and psychosis

Glutamate-related genes have been associated with schizophrenia, but the results have been ambiguous and difficult to replicate. Homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol (MHPG) are the major degradation products of the monoamines dopamine, serotonin and noradrenaline, respectively, and their concentrations in the cerebrospinal fluid (CSF), mainly HVA, have been associated with schizophrenia. In the present study, we hypothesized that CSF HVA, 5-HIAA and MHPG concentrations represent intermediate phenotypes in the association between glutamate-related genes and psychosis. To test this hypothesis, we searched for association between 238 single nucleotide polymorphisms (SNPs) in ten genes shown to be directly or indirectly implicated in glutamate transmission and CSF HVA, 5-HIAA and MHPG concentrations in 74 patients with psychotic disease. Thirty-eight nominally significant associations were found. Further analyses in 111 healthy controls showed that 87% of the nominal associations were restricted to the patients with psychosis. Some of the psychosis-only-associated SNPs found in the d-amino acid oxidase activator (DAOA) and the kynurenine 3-monooxygenase (KMO) genes have previously been reported to be associated with schizophrenia. The present results suggest that CSF monoamine metabolite concentrations may represent intermediate phenotypes in the association between glutamate-related genes and psychosis.
Comparative analysis of the patency of the internal thoracic artery in
the CABG of left anterior descending artery: 6-month postoperative coronary CT
angiography evaluation

To assess the patency of the pedicled right internal thoracic artery with an anteroaortic course and compare it to the patency of the left internal thoracic artery , in anastomosis to the left anterior descending artery in coronary artery bypass grafting by using coronary CT angiography at 6 months postoperatively.



Between December 2008 and December 2011, 100 patients were selected to undergo a prospective coronary artery bypass grafting procedure without cardiopulmonary bypass. The patients were randomly divided by a computer-generated list into Group-1 (G-1) and Group-2 (G-2), comprising 50 patients each, the technique used was known at the beginning of the surgery. In G-1, coronary artery bypass grafting was performed using the left internal thoracic artery for the left anterior descending and the free right internal thoracic artery for the circumflex, and in G-2, coronary artery bypass grafting was performed using the right internal thoracic artery pedicled to the left anterior descending and the left internal thoracic artery pedicled to the circumflex territory.



The groups were similar with regard to the preoperative clinical data. A male predominance of 75.6% and 88% was observed in G-1 and G-2, respectively. Five patients migrated from G-1 to G-2 because of atheromatous disease in the ascending aorta. The average number of distal anastomoses was 3.48 (SD=0.72) in G-1 and 3.20 (SD=0.76) in G-2. Coronary CT angiography in 96 re-evaluated patients showed that all ITAs, right or left, used in situ for the left anterior descending were patent. There were no deaths in either group.



Coronary artery bypass grafting surgery involving anastomosis of the anteroaortic right internal thoracic artery to the left anterior descending artery has an outcome similar to that obtained using the left internal thoracic artery for the same coronary site.
High diagnostic yield of tuberculosis from screening urine samples from HIV-infected patients with advanced immunodeficiency using the Xpert MTB/RIF assay.

We determined the diagnostic yield of the Xpert MTB/RIF assay for tuberculosis (TB) when testing small volumes of urine from ambulatory HIV-infected patients before starting antiretroviral therapy in South Africa. Compared with a gold standard of sputum culture, the sensitivity of urine Xpert among those with CD4 cell counts of <50, 50-100, and >100 cells per microliter were 44.4%, 25.0%, and 2.7% (P = 0.001), respectively. Urine Xpert testing provides a means of rapid TB diagnosis in patients with advanced immunodeficiency and poor prognosis. These data are indicative of high rates of TB dissemination and renal involvement in this clinical population.
Adiposity and sex hormones in girls.

Greater body fatness during childhood is associated with reduced risk of premenopausal breast cancer, but few studies have addressed the relation of adiposity with sex hormones in girls. We prospectively examined associations between adiposity and circulating levels of sex hormones and sex hormone-binding globulin (SHBG) among 286 girls in the Dietary Intervention Study in Children. Participants were 8 to 10 years old at baseline and were followed for an average of 7 years. Anthropometric measurements were taken at baseline and at subsequent annual visits, and blood samples were collected every 2 years. Concentrations of dehydroepiandrosterone sulfate (DHEAS) during follow-up were higher among girls with greater body mass index (BMI) at baseline. The mean for the lowest BMI quartile was 63.0 microg/dL compared with 78.8 microg/dL for the highest quartile, and each kg/m(2) increment in baseline BMI was associated with a 4.3% increase (95% confidence interval, 1.6-7.0%) in DHEAS levels during follow-up (P(trend) = 0.002). Concentrations of SHBG during follow-up were lower among girls with greater BMI at baseline. The mean for the lowest BMI quartile was 94.8 nmol compared with 57.5 nmol for the highest quartile, and each kg/m(2) increment in baseline BMI was associated with an 8.8% decrease (95% confidence interval, 7.0-10.6%) in SHBG levels during follow-up (P(trend) < 0.0001). Estrogen and progesterone concentrations were similar across BMI quartiles. These findings suggest that adiposity may alter DHEAS and SHBG levels in girls. Whether and how these differences affect breast development and carcinogenesis requires further research.
Pilot physical activity intervention reduces severity of ADHD symptoms in young children.

Physical activity associates with mental health and neurocognitive function, showing potential for addressing ADHD symptoms. As a preliminary assessment of this potential, the authors piloted a before-school physical activity intervention for young children.



Seventeen children (Grades K-3) exhibiting four or more hyperactivity/impulsivity symptoms on the Disruptive Behavior Disorders Rating Scale (Pelham, 2002) completed about 26 min of continuous moderate-to-vigorous physical activity daily over eight school weeks. The authors administered cognitive, motor, social, and behavioral functioning measures at pre- and postprogram, assessed response inhibition weekly, and coded negative behaviors daily.



Several measures showed significant or marginally significant change over time (effect size = 0.35-0.96) with additional measures showing meaningful effect size values (≥ 0.20). Response inhibition effects were most consistent. Most participants (64% to 71%) exhibited overall improvement according to postprogram parent, teacher, and program staff ratings.



Physical activity shows promise for addressing ADHD symptoms in young children.
Large artery ischaemic stroke in severe acute respiratory syndrome (SARS)

Of the 206 patients who contracted Severe Acute Respiratory Syndrome (SARS) in Singapore five developed large artery cerebral infarctions. Four patients were critically-ill and three died. Intravenous immunoglobulin was given to three patients. An increased incidence of deep venous thrombosis and pulmonary embolism was also observed among the critically-ill patients. We believe our experience warrants an increased vigilance against stroke and other thrombotic complications among critically-ill SARS patients in future outbreaks, especially if treatment such as intravenous immunoglobulin, that increases pro-thrombotic tendency, is contemplated.
