    Standardized protocol to identify high-risk patients undergoing therapeutic apheresis procedures

    JOURNAL OF CLINICAL APHERESIS, Issue 3 2008
    Qun Lu
    Abstract As the scope of therapeutic apheresis (TA) expands and more procedures are requested for critically ill patients, adverse reactions (AR) associated with TA become a major concern for physicians, nurses, patients and their families. To assess the risks for ARs associated with patients' underlying diseases, we developed a preprocedure assessment tool with a set of high-risk criteria which included: (1) unstable vital signs, (2) active nonphysiological bleeding, (3) evidence of severe bronchoconstriction, (4) severe anemia, (5) projected extracorporeal volume (ECV) >15% of total blood volume (TBV) in adults or >10% of TBV in pediatric patients, (6) pregnancy, and (7) conditions requiring continuous nursing support. A standard operating procedure with a "Request for Apheresis Procedure on High-Risk Patient" form and protocol were developed to identify patients as high-risk before initiation of a TA procedure. Here we report our experience in the 3-year period following the implementation of this protocol. During this period, a total of 3,254 TA procedures were performed, 44 of which were for patients identified as high-risk by the protocol. The incidence of overall ARs was 8% for all TA procedures and 45.5% for procedures performed for high-risk patients. The incidence of moderate-to-severe ARs was 3.7% for all TA procedures and 36.4% for procedures performed for high-risk patients. The protocol identified a group of patients with an increased risk for ARs, especially moderate-to-severe reactions during and/or immediately following TA. J. Clin.

    The Reliability of Echocardiographic Left Ventricular Wall Motion Index to Identify High-Risk Patients for Multicenter Studies

    ECHOCARDIOGRAPHY, Issue 1 2006
    Gunnar H. Gislason M.D.
    Objective: To study whether the use of echocardiographic left ventricular (LV) wall motion index (WMI) is a dependable parameter for identifying patients with LV dysfunction to be enrolled in multicenter trials. Methods: Videotaped echocardiographic examinations from 200 randomly selected patients that were screened for inclusion into the DIAMOND-CHF and DIAMOND-MI trials were reevaluated by an external expert echocardiographer. WMI was calculated using the 16-segment LV model. Results: The external echocardiographer systematically found lower values of WMI than the core laboratory. The average difference in WMI was 0.18 (SD: 0.33) in the DIAMOND-CHF trial and 0.09 (SD: 0.33) in the DIAMOND-MI trial. The difference in WMI exceeded 0.33 in 34% of the patients in both trials. The cutoff value for inclusion into the DIAMOND trials was WMI , 1.2. There was an agreement on WMI dichotomized to below or above 1.2 in 82% of the patients in both trials ( , coefficient 0.66 for the DIAMOND-CHF and 0.55 for the DIAMOND-MI). Conclusions: Despite substantial interlaboratory variation in WMI in individual patients and a systematic lower WMI score by the external echocardiographer there was an acceptable overall agreement for identifying patients with severe impairment of LV function. This not only underscores the value of LV-WMI as a useful tool for selecting high-risk patients to be included in multicenter studies but also serves to warn against the use of rigid cutoff values for WMI in the treatment of individual patients.

    Gender- and Age-Related Differences in Treatment and Control of Cardiovascular Risk Factors Among High-Risk Patients With Angina

    JOURNAL OF CLINICAL HYPERTENSION, Issue 7 2005
    Katharine H. Hendrix PhD
    Dyslipidemic, hypertensive patients (N=48,863) were stratified by gender, age, and angina (n=2502) vs. nonangina (n=46,358) status. Comparing 95% confidence intervals yielded significant differences in treatment and cardiovascular risk factor control between subgroups. More men than women bad low-density lipoprotein cholesterol (LDL-C) <100 mg/dL (angina, 43.94-43.96 vs. 34.42-34.50; nonangina, 32.43-32.43 vs. 17.25-17.25) and 100-129 mg/dL (angina, 32.12-32.14 vs. 35.10-35.18; nonangina, 53.86-53.86 vs. 32.44-32.44). More women than men had LDL-C >130 mg/dL (angina, 27.68-27.72 vs. 23.91-23.93; nonangina, 38.70-38.70 vs. 35.38-35.39). Women were less likely than men to receive statins (angina, 69.95-69.99 vs. 82.11-82.13; nonangina, 59.80-59.80 vs. 63.72-63.72), any antilipidemic medication at all (angina, 25.93-25.97 vs. 13.48-13.48; nonangina, 36.73-36.73 vs. 30.73-30.73), or to have current cholesterol measurements (angina, 56.82-56.88 vs. 34.54-34.56; nonangina, 45.77-45.77 vs. 39.75-39.75). Primary care providers treat high-risk patients relatively aggressively; however, opportunities to forestall cardiovascular disease may be missed in hypertensive, dyslipidemic women whose LDL-C is often not measured and controlled.

    Protected Carotid Stenting in High-Risk Patients: Results of the SpideRX Arm of the Carotid Revascularization with ev3 Arterial Technology Evolution Trial

    JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 5 2010
    ROBERT D. SAFIAN M.D.
    Purpose:,A prospective nonrandomized multicenter registry of 160 patients with severe carotid stenosis and high-risk features for carotid endarterectomy was conducted during the 3-month period from March to May 2005. Methods:,Carotid artery stenting (CAS) was performed with the SpideRXÔ Embolic Protection System (ev3, Inc., Plymouth, MN, USA) as part of an investigational device exemption from the Food and Drug Administration. Results:,The primary end-point of major adverse cardiac and cerebrovascular events at 30 days after CAS was observed in nine patients (5.6%), including death in four patients (2.5%), nonfatal stroke in five patients (3.1%), and nonfatal myocardial infarction in one patient (0.6%). A secondary end-point of technical success (defined as successful deployment of all devices, filter retrieval, and final diameter stenosis <50%) was achieved in 156 of 160 patients (97.5%). The only independent predictor of death or stroke at 30 days was baseline stenosis severity (P < 0.05). Conclusion:,CAS with distal embolic protection using the SpideRXÔ Embolic Protection System is a reasonable alternative for revascularization of some high-risk patients with severe carotid stenosis.

    Endovascular Stent Graft Repair of Abdominal Aortic Aneurysms in High-Risk Patients:

    JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2004
    A Single Center Experience
    Background: Endovascular stent graft (EVG) repair can be a safe alternative to open surgical repair to treat abdominal aortic aneurysms (AAA) in high-risk patients. We report our results with EVG repair in such high-risk patients at our institution. Objectives: We wanted to show that EVG repair can be performed successfully and with a low complication rate in patients with serious comorbidities. Methods: All patients prospectively studied underwent EVG repair of AAA from February 2000 to July 2002. Results: Of the 60 patients studied, 45 (75%) were high-risk surgical candidates because of associated comorbidities; their aneurysms ranged from 4.5 to 10 cm (mean: 5.7 ± 1.2 cm). Fifty-nine of 60 patients (98.3%) were treated successfully. Two (3.3%) who underwent surgical intervention for site-related complications died from postoperative complications. Hospital stay was <48 hours in 46 (77%) patients. Conclusion: Our preliminary results show that EVG is safe, feasible, and yields excellent technical success even in patients at high risk for complications. Teamwork between interventional cardiologists and vascular surgeons is advised. (J Interven Cardiol 2004;17:71,79) [source]

    Assessment of Microvolt T-Wave Alternans in High-Risk Patients with the Congenital Long-QT Syndrome

    ANNALS OF NONINVASIVE ELECTROCARDIOLOGY, Issue 4 2009
    Jörn Schmitt M.D.
    Background: Microvolt T-wave alternans (MTWA) has been used for arrhythmogenic risk stratification in cardiac disease conditions associated with increased risk of sudden cardiac death. Macroscopic T-wave alternans has been observed in patients with congenital long-QT syndrome (LQTS). The role of MTWA testing in patients with LQTS has not been established. Objective: To determine the diagnostic value of MTWA testing in high-risk patients with LQTS. Methods and results: We assessed MTWA in 10 consecutive LQTS index patients who survived cardiac arrest or had documented torsade de pointes tachycardia and 6 first-degree family members with congenital LQTS which had been genotyped in 13 of 16 subjects (7 index patients, 6 family members). No LQTS-causing mutation was identified in 3 index patients with overt QT prolongation. MTWA was assessed during standardized bicycle exercise testing using the spectral method and yielded negative (n = 8) or indeterminate (n = 2) results in index patients, respectively. Similarly, all first-degree family members tested MTWA negative except for one indeterminate result. Two genotype positive family members could not be tested (two children,4 and 9 years of age). Conclusion: In patients with congenital LQTS, free from structural heart disease and with a history of life-threatening cardiac arrhythmias, assessment of MTWA does not yield diagnostic value. Hence, determination of MTWA in lower risk LQTS patients without spontaneous arrhythmic events is likely not to be useful for arrhythmia risk stratification. [source]


    Efficacy and Safety of Tirofiban in High-Risk Patients With Non-ST-Segment Elevation Acute Coronary Syndromes

    CLINICAL CARDIOLOGY, Issue 9 2009
    Zhenxian Yan MD
    Objective To evaluate the safety and efficacy of tirofiban in high risk patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) after percutaneous coronary intervention (PCI). Methods A total of 240 patients were randomized to either a tirofiban group or a control group. Results Compared with the control group, the platelet aggregation rate in the tirofiban group was lower (P < 0.01); the plasma levels of CK-MB and troponin I, cardiac form (cTnI) were lower (P < 0.05); ECG improved significantly (P < 0.05); the incidence of major adverse cardiac events (MACE) was lower (P < 0.05); and there was no difference in bleeding complications between the 2 groups (P = 0.1). Conclusions The administration of tirofiban in high risk patients with NSTE-ACS after PCI is safe and effective. Copyright © 2009 Wiley Periodicals, Inc. [source]


    Safety and Efficacy of Bivalirudin in High-risk Patients Admitted Through the Emergency Department

    ACADEMIC EMERGENCY MEDICINE, Issue 8 2009
    Chadwick D. Miller MD
    Abstract Objectives:, The objective was to assess the safety and efficacy of bivalirudin monotherapy in patients with high-risk acute coronary syndrome (ACS) presenting to the emergency department (ED). Methods:, Data from the Acute Catheterization and Urgent Intervention Triage StrategY (ACUITY) trial were used to conduct a post hoc subgroup analysis of high-risk ACS patients (cardiac biomarker elevation or ST-segment deviation) who initially presented to the ED. The ACUITY trial randomized patients to receive heparin (unfractionated [UFH] or enoxaparin) plus glycoprotein IIb/IIIa inhibition (GPI), bivalirudin plus GPI, or bivalirudin monotherapy. Endpoints included composite ischemia, major bleeding (not coronary artery bypass graft (CABG) related), and net clinical outcome (major bleeding plus composite ischemia). Results:, Of 13,819 participants in the ACUITY trial, 6,441 presented initially to the ED, met high-risk criteria, and were included in the primary analysis. Bivalirudin alone when compared to heparin plus GPI, after adjusting for covariates, was associated with an improvement in net clinical outcome (12.3% vs. 14.3%, adjusted odds ratio [OR] = 0.81, 95% confidence interval [CI] = 0.66 to 0.99), similar composite ischemia (9.3% vs. 9.1%, adjusted OR = 0.98, 95% CI = 0.77 to 1.24), and less major bleeding (4.0% vs. 6.8%, adjusted OR = 0.57, 95% CI = 0.42 to 0.75). Bivalirudin plus GPI when compared to heparin plus GPI had similar net clinical outcome (13.8% vs. 14.3%, adjusted OR = 0.91, 95% CI = 0.75 to 1.11), composite ischemia (8.8% vs. 9.1%, adjusted OR = 0.87, 95% CI = 0.69 to 1.11), and major bleeding (6.8% vs. 6.8%, adjusted OR = 1.01, 95% CI = 0.79 to 1.30). Conclusions: Bivalirudin monotherapy decreases major bleeding while providing similar protection from ischemic events compared to heparin plus GPI in patients with high-risk ACS admitted through the ED.

    Liver dysfunction after chemotherapy in lymphoma patients infected with hepatitis C

    EUROPEAN JOURNAL OF HAEMATOLOGY, Issue 5 2008
    Omer Dizdar
    Abstract Reactivation of hepatitis B virus (HBV) infection in asymptomatic hepatitis B surface antigen carriers undergoing chemotherapy or immunosuppressive therapy is a well-documented complication. However, data on the consequence of chemotherapy on the course of hepatitis C virus (HCV) infection in HCV(+) patients have been controversial. Here, we review the current knowledge about the complications related to HCV in lymphoma patients receiving chemotherapy/immunosuppressive therapy. Although less frequent than HBV, these complications occur in a subset of patients with mortality rates up to 45%. Therefore, baseline screening for HBV and HCV before initiation of chemotherapy is crucial. High-risk patients having chronic active hepatitis, high baseline HCV viral load, HBV co-infection and receiving cytotoxic drugs, corticosteroids and rituximab (particularly if combined) should be closely monitored for serum transaminase, bilirubin and HCV RNA levels.

    Preoperative risk assessment for gastrostomy tube placement in head and neck cancer patients

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 5 2001
    John M. Schweinfurth MD
    Abstract Background The presentation and definitive surgical treatment of head and neck malignancies have varying impact on postoperative recovery and return of swallowing function, which heretofore has not been well defined. Methods We performed a retrospective chart review of 142 patients who underwent extirpative surgery for head and neck cancer. Results Factors significantly associated with the need for long-term postoperative nutritional support (p < .05) included heavy alcohol use, tongue base involvement and surgery, pharyngectomy, composite resection, reconstruction with a myocutaneous flap, radiation therapy, tumor size, and moderately-to-poorly differentiated histology. Heavy alcohol users were at an absolute risk for gastrostomy tube dependence; patients who underwent radiation therapy, flap reconstruction, tongue base resection, and pharyngectomy were at a two to sevenfold increased risk for gastrostomy tube dependence, respectively. Conclusions High-risk patients based on these criteria should receive a feeding gastrostomy at the time of their initial surgical therapy. © 2001 John Wiley & Sons, Inc. Head Neck 23: 376,382, 2001.

    Hypothalamic,Pituitary,Adrenocortical Axis Dysregulation in Acute Temporomandibular Disorder and Low Back Pain: A Marker for Chronicity?,

    JOURNAL OF APPLIED BIOBEHAVIORAL RESEARCH, Issue 3-4 2006
    John P. Garofalo
    Dysregulation of the hypothalamic,pituitary,adrenocortical (HPA) axis is believed to be a valid biological marker of stress. This study evaluating changes in patients with temporomandibular disorders (TMD) and low back pain (LBP) to determine whether dysregulation of this system represents a marker for chronicity. Salivary cortisol samples were collected from 78 patients (TMD = 41, LBP = 37) upon waking up and 20 minutes later daily for 2 weeks. High-risk patients for chronic pain had different overall cortisol levels versus low-risk patients. High-risk patients exhibited greater variability in terms of cortisol secretion compared with low-risk patients, F(1, 1,243) = 17.73, p < .000. These results provide evidence of a neuroendocrine mechanism underlying a constellation of psychosocial risk factors for chronic pain. [source]


    Elective Intraaortic Balloon Counterpulsation in High-Risk Off-Pump Coronary Artery Bypass Grafting

    JOURNAL OF CARDIAC SURGERY, Issue 1 2006
    Hunaid A. Vohra M.R.C.S.
    However, the benefits of insertion of IABP electively in high-risk off-pump coronary artery bypass grafting (OPCAB) have not been established. Six hundred and twenty-five patients who underwent OPCAB form the study group. High-risk patients fulfilling two or more of the following: left main stem stenosis >70%, unstable angina, and poor left ventricular function, who had elective insertion of IABP preoperatively by the open technique (group I; n = 20) were compared with a similar high-risk group that did not (group II; n = 25). There were no significant differences in risk factors between the two groups (Euroscore 5.68). The mean number of grafts was similar. Postoperatively, there were no significant differences in the need for inotropes, duration of ventilation, arrhythmias, cerebrovascular, gastrointestinal, and infective complications (p = NS). There were no IABP-related complications. Acute renal failure requiring hemofiltration was higher in group II (n = 5; p < 0.05). Four patients (16%) in group II required postoperative IABP. Although intensive care stay was longer in group I (27.6 ± 15.3 vs. 18.6 ± 9.1 hours; p < 0.05), patients in group I were discharged earlier from hospital. There was no difference in mortality between the two groups (n = 1 in each group). In high-risk patients undergoing OPCAB, routine preoperative insertion of IABP electively reduces the incidence of acute renal failure. In addition it avoids the need for emergency insertion postoperatively and may result in earlier discharge. [source]


    Goal attainment for multiple cardiovascular risk factors in community-based clinical practice (a Canadian experience)

    JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 1 2009
    Pendar Farahani MD MSc
    Abstract Background, The primary goal in the clinical management of atherosclerotic cardiovascular (CV) disease is to reduce major CV risk factors. A single risk factor approach has been traditionally used for demonstrating effectiveness of therapeutic interventions designed to reduce CV risk in clinical trials, but a global CV risk reduction approach should be adopted when assessing effectiveness in the clinical practice setting. Objectives, To explore combined goal achievement for low-density lipoprotein cholesterol (LDL-C), fasting plasma glucose and systolic-diastolic blood pressure, in patients with dyslipidemia on pharmacotherapy in community-based clinical practices across Canada. Methods, In a cross-sectional study, patients filling a prescription for any antihyperlipidemia therapy in selected pharmacies in Ontario, Quebec, British Columbia and Nova Scotia were recruited. Family physicians of the participating patients were requested to provide information from the patient's medical record. Ten-year CV risk was identified for each patient according to the Framingham criteria. Results, High-risk patients comprised 52% of the patient population; 34% were moderate-risk and 14% were low-risk. Patients had a mean of 2.8 CV risk factors; high-risk 3.7, moderate-risk 2.3 and low-risk 1.2. LDL-C goal attainment was observed in 62%, 79% and 96% of patients in high-risk, moderate-risk and low-risk strata respectively. BP goal was achieved in high-risk patients 58%, moderate-risk 83% and low-risk 95%. Glucose levels were below the threshold in 91% of patients. Complete global CV risk reduction was achieved in only 21%, 66% and 92% of high-risk, moderate-risk and low-risk strata respectively. Conclusion, This study illustrates that many patients with dyslipidemia in the Canadian population, and in particular the high-risk patients, did not meet the therapeutic targets for specific CV risk factors according to the Canadian guidelines. Overall, 54% of patients failed to achieve a state of complete global CV risk reduction. [source]


    Abnormal Nocturnal Heart Rate Variability and QT Dynamics in Patients with Brugada Syndrome

    PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 2007
    BERTRAND PIERRE M.D.
    Background: In Brugada syndrome (BSY), most of the ventricular arrhythmic events are nocturnal, suggesting an influence of the autonomic nervous system. Methods: In 46 patients (mean age = 41 ± 14 years, 43 men) with electrocardiograms (ECG) consistent with BSY and structurally normal hearts, we measured heart rate variability (HRV) and QT dynamics (QT/RR slopes) on 24-hour ambulatory ECG. Type 1 BSY-ECG was spontaneous in 23 (50%) and induced in 23 patients. Results: History of syncope was present in 23 patients (50%). Programmed ventricular stimulation induced ventricular tachyarrhythmias (VTA) in 13 patients (28%). A single patient developed ventricular tachycardia during a mean follow-up of 34 months. Compared to a control group matched for age and sex, HRV was decreased over 24 hours and during nighttime in patients with BSY (SDNN 122 ± 44 vs 93 ± 36 ms, P = 0.0008 and SDANN 88 ± 39 vs 54 ± 24 ms, P < 0.0001). QTend /RR slopes were decreased over 24 hours in patients with BSY (0.159 ± 0.05 vs 0.127 ± 0.05, P = 0.003) and particularly at night (0.123 ± 0.04 vs 0.089 ± 0.04, P = 0.0001). QTend /RR slopes were significantly decreased during nighttime in patients with spontaneous versus provoked BSY-ECG patterns. By contrast, HRV and QT/RR slopes were similar in symptomatic and asymptomatic patients, whether VTA were induced or not. Conclusions: Patients with a BSY-ECG pattern had lower HRV and QT/RR slopes than control subjects during nighttime. High-risk patients with spontaneous BSY-ECG patterns had the lowest nocturnal QTend/RR slopes. These unique repolarization dynamics might be related to the frequent nocturnal occurrence of VTA in BSY. [source]


    Combinations of cytogenetics and international scoring system can predict poor prognosis in multiple myeloma after high-dose chemotherapy and autologous stem cell transplantation,

    AMERICAN JOURNAL OF HEMATOLOGY, Issue 5 2009
    Yoshihiro Inamoto
    High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is a standard therapy for newly diagnosed multiple myeloma. Combinations of recently proposed prognostic factors such as cytogenetics and international scoring system (ISS) may be useful to predict prognosis after ASCT. This study evaluated 60 consecutive patients who underwent ASCT in four institutes. The median age of patients was 57 years old. Cytogenetic analyses of bone marrow at diagnosis detected metaphase abnormalities in 9 of 51 patients and interphase abnormalities in six of 35 patients (17p13 deletion, t(4;14) and t(14;16)). Seventeen patients had ISS stage 3 at diagnosis. Twenty-five patients who had any of these risk factors were defined as high risk. All patients were conditioned with high-dose melphalan. With a median follow-up of 3.4 years, overall survival and event-free survival at 3 years were significantly worse in high-risk patients (48% vs. 97%; P = 0.0005 and 16% vs. 37%; P = 0.038, respectively) despite the higher CR plus VGPR rate among high-risk patients. In addition, survival at 1 year after progression was significantly worse in high-risk patients despite salvage chemotherapy containing thalidomide (32% vs. 100%, P = 0.0001). Combinations of cytogenetics and ISS could readily predict prognosis. Quality of response is a poor surrogate marker for ultimate outcome. High-risk patients may need more effective treatment. Am. J.

    Skin-sparing mastectomy and immediate reconstruction is an acceptable treatment option for patients with high-risk breast carcinoma

    CANCER, Issue 5 2005
    Kevin J. Downes
    Abstract BACKGROUND Skin-sparing mastectomy (SSM) followed by immediate reconstruction is an effective treatment option for patients with early-stage breast carcinoma, but its use in patients with more advanced disease is controversial. METHODS A retrospective review was performed that included 38 consecutive patients with high-risk breast carcinoma who underwent SSM and immediate reconstruction (between July 1996 and January 2002). Tumor characteristics, type of reconstruction, margin status, timing of adjuvant therapy, postoperative complications, and incidence of recurrence were evaluated. RESULTS High-risk patients (Stage IIA [n = 4 patients] Stage IIB [n = 23 patients] Stage IIIA [n = 8 patients] and Stage IIIB [n = 3 patients]) underwent immediate reconstruction after SSM with the use of a transverse rectus abdominis myocutaneous flap (n = 31 patients), a latissimus dorsi myocutaneous flap plus an implant (n = 3 patients), or tissue expanders with subsequent implant placement (n = 4 patients). The median follow-up was 52.9 months (range, 27.5,92.0 months), and the median time to recurrence has not yet been reached at the time of last follow-up. The median interval from surgery to the initiation of postoperative adjuvant therapy was 38 days (range, 25,238 days). Local recurrence was seen in 1 patient (2.6%), systemic recurrence in was seen in 10 patients (26.3%), and both local and distant metastases in were seen in 2 other patients (5.3%). CONCLUSIONS SSM with immediate reconstruction appeared to be an oncologically safe treatment option for high-risk patients with advanced stages of breast carcinoma. In addition to the aesthetic and psychological benefits of performing SSM with immediate reconstruction, local recurrence rates and disease-free survival were favorable when combined with the use of radiation therapy and adjuvant chemotherapy, as indicated.

    Genetic Counseling and the Advanced Practice Oncology Nursing Role in a Hereditary Cancer Prevention Clinic: Hereditary Breast Cancer Focus (Part I)

    THE BREAST JOURNAL, Issue 2009
    Carrie L. Snyder MSN
    Abstract:, Interest in hereditary breast cancer has increased rapidly among all health care providers as well as the laity. A major problem for health care providers, however, is the time and skill required for gathering family history, interpreting the pedigree, and providing genetic counseling for the high-risk patient so that BRCA testing, when indicated, can be pursued and screening and prevention strategies employed by the patient. The fields of hereditary cancer and molecular biology have developed at a rate that makes it difficult for physicians to keep up with this explosive knowledge. Therefore, "Who is going to take care of all of these crucial matters for patient benefit?" is a germane question. Our experience has confirmed that the advanced practice oncology nurse who is interested in cancer genetics can become skilled at providing this service to the patient and his/her family. This study portrays the role of such an oncology nurse in meeting this important public health challenge, with special attention devoted to the logistics of this role in the rapidly emerging field of hereditary breast cancer.

    High serum cardiac troponin T concentrations in preterm infants with respiratory distress syndrome,

    ACTA PAEDIATRICA, Issue 9 2000
    D Trevisanuto
    In preterm infants with respiratory distress syndrome (RDS), cardiac function is negatively influenced by the severity of the lung disease. On day 2 of life, cardiac troponin T (cTnT), biochemical marker of myocardial injury, was measured in 46 preterm infants (gestational age ,32 wk), 26 with RDS and 20 without: median (range) 0.38 (0.02,1.57) ,gL vs 0.13 (0.02,0.85) ,gL, respectively. Conclusion: High cTnT concentrations in preterm infants with RDS suggest the presence of myocardial damage in this group of high-risk patients. [source]


    Homicide and schizophrenia: maybe treatment does have a preventive effect

    CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2001
    Martin Erb
    Background Persons with schizophrenia have been found to be at increased risk for homicide as compared with the general population. The increased risk may be associated with the implementation of the policy of deinstitutionalization. Method Persons with schizophrenia who had committed or attempted homicide in the German state of Hessen from 1992 to 1996 and in the Federal Republic of Germany from 1955 to 1964 were compared. Results Schizophrenia increased the risk of homicide 16.6 times (95% CI 11.2,24.5) in the recent cohort and 12.7 times (95% CI 11.2,14.3) in the older cohort. These odds ratios are not statistically different. The lack of appropriate services for chronic high-risk patients and the non-use of mental health services by first episode, acutely psychotic patients were associated with homicide. Conclusion There has been no increase in the risk of homicide among persons with schizophrenia since the implementation of the policy of deinstitutionalization. The examination of the recent period suggests that the provision of specialized long-term care to persons with schizophrenia who are at high risk for violent behaviour and the use of mental health services by acutely psychotic persons may reduce the risk of homicide.

    Prevalence of Methicillin-Resistant Staphylococcus aureus in the Setting of Dermatologic Surgery

    DERMATOLOGIC SURGERY, Issue 3 2009
    ROGER S. SICA DO
    BACKGROUND The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the postoperative setting of dermatologic surgery is unknown. Such data could influence the empirical treatment of suspected infections. OBJECTIVE To examine the period prevalence of MRSA infections in the postoperative setting of dermatologic surgery. METHODS We performed chart reviews of 70 patients who had bacterial cultures taken from January 2007 to December 2007. In the 21 postsurgical cases, we analyzed age, risk factors, sites of predilection, method of repair, and pathogen of growth. RESULTS The mean age of the overall study population was 57, with the mean age of postsurgical MRSA-positive cases being 75.5. Of the 21 postsurgical cultures taken, 16 cultures grew pathogen, and two of the 16 (13%) pathogen-positive cultures grew MRSA. LIMITATIONS This is a retrospective chart review of a relatively small sample size in one geographic location. Our patient population is known to contain a large number of retirees. CONCLUSION The increasing prevalence of MRSA skin and soft tissue infections and recommendation to modify empirical antibiotic therapy have been well documented in particular patient populations, but we caution against the empirical use of MRSA-sensitive antibiotics in the postoperative setting of dermatologic surgery. We advocate culturing all infectious lesions upon presentation and reserve empirical use of MRSA-sensitive antibiotics for high-risk patients or locations. [source]


    Antibiotic Prophylaxis Guideline Awareness and Antibiotic Prophylaxis Use Among New York State Dermatologic Surgeons

    DERMATOLOGIC SURGERY, Issue 9 2002
    Noah Scheinfeld JD
    background. Use of antibiotic prophylaxis in dermatologic surgery patients remains controversial and several sets of guidelines exist. objective. We investigated dermatologic surgeon's awareness of the American Heart Association (AHA) 1997 antibiotic prophylaxis guidelines, their use of prophylactic antibiotics, and their practices as compared with the Haas and Grekin's 1995 antibiotic prophylaxis guidelines. methods. We mailed postage-paid questionnaires regarding AHA guideline awareness and antibiotic prophylaxis use to the 235 New York State members of the American Society for Dermatologic Surgery (ASDS). We received 87 replies. results. Most participants recognize AHA guidelines and claim to follow them. We reiterate previous studies' findings. Most dermatologic surgeons use antibiotics appropriately. However, antibiotics are occasionally overused or dosed outside the guidelines. Many participants prescribe antibiotics based on a patient's other physicians' recommendations. Notably, erythromycin is sometimes used, an antibiotic the AHA no longer recommends. conclusion. Dermatologic surgeons commonly use antibiotic prophylaxis to prevent bacterial endocarditis. Based on previous studies, though, the risk of endocarditis following cutaneous surgery is low and thus the use of antibiotic prophylaxis is controversial. Although this practice is appropriate for high-risk patients when skin is contaminated, it is not recommended for noneroded, noninfected skin. We report that dermatologists may be aware of the guidelines, but only seem to partially follow them. Further studies are still needed to establish optimal guidelines. [source]


    Corrected head circumference centiles as a possible predictor of developmental performance in high-risk neonatal intensive care unit survivors

    The aim of this study was to evaluate the predictive value of corrected head circumference (HC) centiles at 2 years of age with respect to developmental performance in a series of high-risk neonatal intensive care unit (NICU) survivors with microcephaly. The study used a retrospective review of the clinical files of children seen in a clinic devoted to the follow-up of all high-risk survivors of a hospital's level III NICU. All children with microcephaly (occipital-frontal circumference below the 2nd centile for sex) at 2 years of age were identified. The HC obtained at 2 years was corrected to the ages for which the absolute HC corresponded to either the 50th or 2nd centile for the child's sex. Of 312 high-risk patients followed, 38 (12.2%) were microcephalic. Fifteen performed below the 50th age-corrected HC centile (severe developmental delay), 12 performed between the 50th and 2nd age-corrected HC centile (moderate developmental delay), and 11 performed above the 2nd age-corrected HC centile (mild developmental delay). The absolute value of HC measurement was not a predictor of developmental performance. Of all clinical factors evaluated, only coexisting epilepsy was found to be a significant predictor of less than the 50th age-corrected HC centile developmental performance (Chi2=6.134, p=0.01). We conclude that in a high-risk population, the presence of microcephaly implies developmental impairment, though neither the absolute HC measurement nor the corrected HC centile is predictive. Coexisting epilepsy in this context appears to worsen developmental outcome. [source]


    Evaluation of a Pediatric-sedation Service for Common Diagnostic Procedures

    ACADEMIC EMERGENCY MEDICINE, Issue 6 2006
    Wendalyn K. King MD
    Abstract Background: Pediatric patients often require sedation for diagnostic procedures such as magnetic resonance imaging and computed tomography scanning. In October 2002, a dedicated sedation service was started at a tertiary care pediatric facility as a joint venture between pediatric emergency medicine and pediatric critical care medicine. Before this service, sedation was provided by the department of radiology by using a standard protocol, with high-risk patients and failed sedations referred for general anesthesia. Objectives: To describe the initial experience with a dedicated pediatric-sedation service. Methods: This was a retrospective analysis of quality-assurance data collected on all sedations in the radiology department for 23-month periods before and after sedation-service implementation. Study variables were number and reasons for canceled or incomplete procedures, rates of referral for general anesthesia, rates of hypoxia, prolonged sedation, need for assisted ventilation, apnea, emesis, and paradoxical reaction to medication. Results are reported in odds ratios (OR) with 95% confidence intervals (95% CI). Results: Data from 5,444 sedations were analyzed; 2,148 before and 3,296 after sedation-service activation. Incomplete studies secondary to inadequate sedation decreased, from 2.7% before the service was created to 0.8% in the post,sedation-service period (OR, 0.29; 95% CI = 0.18 to 0.47). There also were decreases in cancellations caused by patient illness (3.8% vs. 0.6%; OR, 0.16; 95% CI = 0.10 to 0.27) and rates of hypoxia (8.8% vs. 4.6%; OR, 0.50; 95% CI = 0.40 to 0.63). There were no significant differences between the groups in rates of apnea, need for assisted ventilation, emesis, or prolonged sedation. The implementation of the sedation service also was associated with a decrease in both the number of patients referred to general anesthesia without a trial of sedation (from 2.1% to 0.1%; OR, 0.33; 95% CI = 0.06 to 1.46) and the total number of general anesthesia cases in the radiology department (from 7.5% to 4.4% of all patients requiring either sedation or anesthesia; OR, 0.56; 95% CI = 0.45 to 0.71). Conclusions: The implementation of a dedicated pediatric-sedation service resulted in fewer incomplete studies related to inadequate sedation, in fewer canceled studies secondary to patient illness, in fewer referrals for general anesthesia, and in fewer recorded instances of sedation-associated hypoxia. These findings have important implications in terms of patient safety and resource utilization. [source]


    Attenuating CV risk factors in patients with diabetes: clinical evidence to clinical practice

    DIABETES OBESITY & METABOLISM, Issue 2002
    Alan J. Garber
    Abstract Individuals with diabetes are at high risk of cardiovascular (CV) disease, a risk that is significantly greater in the presence of traditional CV risk factors (hyperlipidaemia, hypertension, prothrombotic state). Glucose control and management of these risk factors decreases but does not eliminate CV events, reflecting the complexity of atherosclerosis. Novel risk factors (C-reactive protein, lipoprotein a, homocysteine, and endothelial dysfunction) have been proposed and are potentially modifiable. However, clinical trials data are not yet available to guide therapy. At this time, no single agent can achieve adequate risk reduction in patients with diabetes. Even with the use of multiple agents and classes of agents to manage CV risk, 75% of patients with diabetes are expected to die from CV causes. Despite the recent advances in primary and secondary prevention of CV events, new approaches are needed. Data from the Heart Outcomes Prevention Evaluation (HOPE) trial demonstrated that CV risk can be further reduced by the addition of the ACE inhibitor ramipril to the existing treatment regimen of high-risk patients with diabetes.

    Thiazolidinediones: effects on the development and progression of type 2 diabetes and associated vascular complications

    DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 2 2009

    Abstract In addition to reducing hyperglycaemia, the metabolic actions of TZDs (pioglitazone and rosiglitazone) in theory might improve the prognosis of patients with type 2 diabetes. However, it appears from recent data that pioglitazone and rosiglitazone have different cardiovascular risk profiles. The scope of this paper is to examine the benefits and risks of pioglitazone and rosiglitazone. Three large clinical studies (DREAM, and ADOPT with rosiglitazone; PROactive with pioglitazone) have recently been reported. A lower annual rate of decline of ß-cell function observed with rosiglitazone in the ADOPT study, compared with metformin and glyburide (glibenclamide), along with a reduced progression to insulin use seen with pioglitazone in the PROactive study, provides evidence that TZDs are effective in treating progressive hyperglycaemia. In PROactive, although the primary endpoint was not met, pioglitazone was associated with a reduction in a secondary composite endpoint of clinical cardiovascular events in high-risk patients with existing macrovascular disease who were already receiving other glycaemic and cardiovascular medications. Further evidence supporting an anti-atherogenic effect of pioglitazone was gained from the PERISCOPE study of carotid intima-media thickness. Recent controversy concerning a possible increased risk of myocardial infarction associated with rosiglitazone has fuelled uncertainty about the risk,benefit profile of this agent. In 2008, an update of an American Diabetes Association,European Association for the Study of Diabetes consensus statement on initiation and adjustment of therapy in patients with type 2 diabetes advised clinicians against using rosiglitazone. Skeletal fractures have recently emerged as a side effect of both TZDs. Available data suggest that cardiovascular benefits observed with pioglitazone might not be a class effect of TZDs.

    Burtscheidt W, Wölwer W, Schwarz R, Strauss W, Gaebel W. Out-patient behaviour therapy in alcoholism: treatment outcome after 2 years. Acta Psychiatr Scand 2002: 106: 227,232. © Blackwell Munksgaard 2002. Objective:,The main aim of the study was the evaluation of out-patient behavioural approaches in alcohol dependence. Additionally, the persistence of treatment effects and the impact of psychiatric comorbidity in long-term follow-up was examined. Method:,A total of 120 patients were randomly assigned to non-specific supportive therapy or to two different behavioural therapy programmes (coping skills training and cognitive therapy) each comprising 26 weekly sessions; the follow-up period lasted 2 years. Results:,Patients undergoing behavioural therapy showed a consistent trend towards higher abstinence rates; significant differences between the two behavioural strategies could not be established. Moreover, the results indicate a reduced ability of cognitive impaired patients to cope with short-time abstinence violations and at a reduced benefit from behavioural techniques for patients with severe personality disorders. Conclusion:,Behavioural treatment yielded long-lasting effects and met high acceptance; yet, still in need of improvement is the development of specific programmes for high-risk patients. [source]


    Changing aspirin use in patients with Type 2 diabetes in the UKPDS

    DIABETIC MEDICINE, Issue 12 2004
    C. A. Cull
    Abstract Aims To examine the proportion of UK Prospective Diabetes Study (UKPDS) patients with Type 2 diabetes taking aspirin regularly for the primary and secondary prevention of cardiovascular disease (CVD) before and after publication of the 1997 American Diabetes Association (ADA) Clinical Practice Recommendations and the 1998 Joint British Recommendations on the Prevention of Coronary Disease in Clinical Practice. Methods UKPDS annual review data from 1996/7 (n = 3190) and 2000/1 (n = 2467) were used to determine the prevalence of patients taking aspirin regularly in relation to known CVD risk factors and pre-existing CVD. Results Patients taking aspirin regularly were more often male than female (24 vs. 20%, P = 0.0033), older (66 ± 8 vs. 62 ± 9 years, P < 0.0001) and less often Afro-Caribbean than White Caucasian or Indian Asian (11 vs. 23 vs. 22%, respectively, P < 0.0001). Between 1996/7 and 2000/1 aspirin use in patients without pre-existing CVD increased from 17 to 31% (P < 0.0001) and for those with pre-existing CVD from 76 to 82% (P = 0.032). Conclusion The majority of patients with pre-existing CVD were taking aspirin regularly. Although aspirin use in those without pre-existing CVD approximately doubled after publication of the ADA and Joint British Recommendations, less than two-thirds of these high-risk patients were being treated according to guidelines. This may relate to a lack of convincing evidence for primary CVD prevention or failure to adhere to guidelines. It may be that more trial data is needed to convince clinicians of the value of aspirin therapy in Type 2 diabetes. [source]


    The vitamin D receptor gene variant is associated with the prevalence of Type 2 diabetes mellitus and coronary artery disease

    DIABETIC MEDICINE, Issue 10 2001
    J. R. Ortlepp
    Abstract Aims, Vitamin D can influence lipolysis and insulin secretion. A common genetic polymorphism of the vitamin D receptor, which has been found to be associated with bone mineral density, has also been reported to be associated with insulin-dependent diabetes mellitus. To test the influence of the vitamin D receptor polymorphism on the prevalence of Type 2 diabetes mellitus and coronary artery disease we studied a population of high-risk patients, who were referred to our clinic for diagnostic coronary angiography. Methods, A total of 293 patients considered at high risk for coronary artery disease because of angina pectoris and known hypercholesterolaemia underwent diagnostic coronary angiography. The BsmI vitamin D receptor polymorphism was analysed by polymerase chain reaction. Results, Prevalence of Type 2 diabetes mellitus and coronary artery disease was gradually dependent on the number of B alleles (BB 28%, Bb 13%, bb 8% for Type 2 diabetes mellitus, P = 0.002; BB 88% Bb 72%, bb 66% coronary artery disease, P = 0.01). Patients with the BB genotype had an odds ratio of 3.64 (95% confidence interval 1.53,8.55, P = 0.002) to have Type 2 diabetes mellitus compared with patients with the bb genotype. Conclusions, The genotype of the vitamin D receptor polymorphism determines the prevalence of Type 2 diabetes mellitus and coronary artery disease in a high-risk cohort population. Diabet.
