    Background: QT dispersion (QTd) is equal to longer QTc minus shorter QTc measured by 12-lead electrocardiogram (ECG). QTd reflects inhomogeneity in repolarization of ventricular myocardium and because of easy and fast measurement of QTd, it can be used to predict high-risk patients for dysrhythmia after Acute Myocardial Infarction (AMI). Objectives: This study aimed to assess the effect of thrombolytic therapy on QTd before and 1 hour and 4 days after beginning of thrombolytic therapy. Patients and Methods: The patients with chest pain and ST Elevated Myocardial Infarction (STEMI) that underwent thrombolytic therapy were enrolled into this study. Streptokinase was the thrombolytic agent in all the patients. Standard 12-lead (ECG) was evaluated before beginning of thrombolytic therapy (QTd 1) and 1 hour (QTd2) and 4 days (QTd3) after thrombolytic therapy. First, ECG was magnified × 10 for exact calculation of QT and QTd. After all, the variables were compared using one–way analysis of variance (ANOVA). Besides, P ≤ 0.05 was considered as statistically significant. Results: This study was conducted on 160 patients. The results revealed no significant differences among QTd 1, QTd 2, and QTd 3 (P > 0.05). At inferior AMI, however, a significant difference was observed among QTd1, QTd2, and QTd3 (P = 0.031). Conclusions: Thrombolytic therapy had no significant effects on QTd. Thus, thrombolytic therapy does not increase the risk of arrhythmia. PMID:25614860

    We evaluated 50 consecutive patients who received thrombolytic therapy for acute myocardial infarction using thallium-201 single photon emission computed tomography in combination with oral dipyridamole to assess the frequency of residual myocardial ischemia. Thallium studies were performed early after myocardial infarction at a mean of 4.6 days. The time from the onset of chest pain to the administration of thrombolytic therapy was 2.6 hours (range 0.5 to 5.5). Q wave myocardial infarction was evident in 46 patients; four patients had a non-Q wave infarction (anterior infarction in 31 patients and inferior infarction in 19 patients). The serum mean peak creatinine kinase was 1503 IU/L (range 127 to 6500). Coronary angiography was performed in all patients at a mean of 3.1 days (range 2 to 10) and revealed the infarct-related vessel to be patent in 36 patients (72%). The ejection fraction was 48% (range 26% to 67%). After dipyridamole administration, 13 patients (26%) developed angina that was easily reversed with the administration of intravenous aminophylline. Systolic blood pressure decreased from 122 to 115 mm Hg (p less than 0.05) and the heart rate increased from 76 to 85 beats/min (p less than 0.05). None of the patients had significant hypotension, arrhythmias, or evidence of infarct extension. Perfusion abnormalities were present on the initial thallium images in 48 patients. Redistribution suggestive of ischemia was present in 36 patients (72%). Ischemia confined to the vascular distribution of the infarct vessel was evident in 22 patients. Seven patients had ischemia in the infarct zone as well as in a remote myocardial segment. Thus 29 patients (58%) had ischemia in the distribution of the infarct vessel. Ischemia in the infarct zone was evident in 19 of 36 patients with open infarct vessels and in 10 of 14 patients with occluded infarct vessels.

    Thrombolytic therapy has been studied in acute ischemic stroke, intracranial hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, and sagittal sinus thrombosis. This form of therapy has an evolving role in contemporary neurologic practice, and increased investigational fervor will ensure more exacting therapeutic alternatives for stroke victims in the future.

    Consensus regarding the use of thrombolysis to treat acute pulmonary embolism has not yet been reached. There is good evidence that thrombolytic agents dissolve clot more rapidly than heparin. However, proving that this benefit reduces the death rate from pulmonary embolism has been difficult. Each of the 3 thrombolytic agents (tissue type-plasminogen activator, streptokinase and urokinase) is equally efficacious at dissolving clot, but all are associated with an increased risk of major hemorrhage when compared with heparin. One evolving position is that, in addition to patients presenting in circulatory collapse, for whom thrombolysis has been demonstrated to be life-saving, a subgroup of patients may be identified by echocardiography, through its ability to assess right ventricular dysfunction, who should also be considered for thrombolytic therapy. It remains to be seen whether this approach can reduce the death rate associated with pulmonary embolism. PMID:11129828

    In this paper, we report our experience from a prospective study in 40 ischemic stroke patients admitted during the last two years at University Department of Neurology Stroke Unit, Banja Luka Clinical Center, in order to assess the safety and efficacy of thrombolytic therapy, the impact of age, sex and risk factors, and functional outcome at 6 months of intravenous tissue plasminogen activator treatment. According to the National Institutes of Health Stroke Scale, there were 5 mild, 22 moderate and 13 severe stroke cases in the study group. The outcome measures at 6 months of thrombolytic treatment were taken in 38 (100%) patients, yielding a Functional Independent Measure score > or=90 (good clinical outcome) in 21 (52.50%) and modified Rankin Score < or =2 (good clinical outcome) in 22 (55%) patients. The rate of symptomatic intracerebral hemorrhage in tissue plasminogen activator treated patients was 5%, with a mortality rate of 17.50%. The outcomes were comparable with those found in the NINDS t-PA trial. Current guidelines recommend a 'door-to-needle' time of less than 60 minutes and emphasize that 'time is brain'.

    OBJECTIVE: To determine the availability of thrombolytic therapy in rural Newfoundland and Labrador. DESIGN: Self-administered questionnaire mailed to staff at health care facilities. Respondents were sent two reminders by mail, and questionnaires not returned were completed through telephone interviews. SETTING: Rural health care facilities, including hospitals, 24-hour clinics and satellite clinics. PARTICIPANTS: All chief medical officers, nursing supervisors and administrators in the 34 government-funded rural health care facilities in Newfoundland and Labrador. OUTCOME MEASURES: Number of facilities offering thrombolytic therapy to patients with acute myocardial infarction (AMI) in 1992. For each facility: number of patients presenting with AMI during that year, number of these patients who received thrombolytic therapy, number of staff trained in advanced cardiac life support, travel time to the nearest referral centre, population served and number of beds. RESULTS: Of the 34 rural health care facilities in Newfoundland and Labrador, 91% (31/34) responded to the survey. Thrombolytic therapy was offered in 93% (13/14) of the rural hospitals, 22% (2/9) of the 24-hour clinics and none of the single-physician satellite clinics. In 1992, 390 patients with AMI presented to these health care facilities; 39% of these patients presented to facilities that did not offer thrombolytic therapy. CONCLUSIONS: Thrombolytic therapy has been successfully introduced in many of the rural and isolated health care facilities in Newfoundland and Labrador. An important factor in this success is continuing medical and nursing education on the effectiveness of thrombolytic therapy and the skills needed to provide it. Cost-effectiveness data are needed to determine whether it is reasonable to offer this therapy in isolated, low-volume clinics. More research on the outcomes in patients receiving thrombolytic therapy in rural facilities is also needed. PMID:7820799

    Background The aim of this study was to investigate the potential value of apparent diffusion coefficient (ADC) of diffusion-weighted imaging (DWI) in the prognosis of patients with hyperacute cerebral infarction (HCI) receiving intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA). Material/Methods From June 2012 to June 2015, 58 cases of HCI (<6 h) undergoing rt-PA intravenous thrombolytic therapy (thrombolysis group) and 70 cases of HCI (<6 h) undergoing conventional antiplatelet and anticoagulant therapy (control group) in the same period were collected. DWI was conducted on all the subjects, and ADC maps were generated with Functool software to quantify ADC value. The clinical outcomes of HCI patients were observed for 3 months, and prognostic factors were analyzed. Results Before thrombolysis treatment, the lesion area presented high signal intensity on DWI map and low signal intensity on ADC map, and gradually weakened signal intensity on DWI map and gradually enhanced signal intensity on ADC map were observed after thrombolysis. The ADC values of the thrombolysis group were significantly higher than those of the control group after treatment (24 h, 7 d, 30 d, and 90 d) (all P<0.05), and the ADC and rADC values in the thrombolysis group gradually increased over time (all P<0.05). Multiple logistic regression analysis showed that baseline National Institutes of Health Stroke Scale (NIHSS) score, baseline rADC value, and stroke history were the independent factors for the prognosis of HIC patients with thrombolysis (all P<0.05). Conclusions The values of ADC and rADC may provide guidance in the prognosis of HCI patients receiving rt-PA, and the baseline rADC value is the protective factor for the prognosis of HCI patients receiving rt-PA.

    In the period of two years the authors treated at the coronary care unit 146 patients inflicted by the acute myocardial infarction (AMI). In 15 of them (13 men, 2 women, 13 times Q and twice non-Q, 5 times anterior, 10 times inferior) they performed intravenous thrombolytic treatment by use of streptokinase. The success rate of the thrombolytic therapy was evaluated by noninvasive markers: 1.) rapid withdrawal of chest pain, 2.) rapid (in 6 hours) and essential improvement of ST segment elevation and 3.) presence of reperfusion arrhythmias (in 6 hours). The authors detected insufficient medicinal conciousness among their health district population as regard to their response after the AMI origin (absolute majority of patients delayed their arrival). Minor complications due to therapy (allergy and minor local hemorrhage) occurred in 4 patients. Nobody died. Only those cases were considered as being successful, in which all three success rate markers were present. This condition was fulfilled in 8 patients (i.e. in 53% of cases) and with minor insufficiencies in further two patients (which would increase the percentage of the success rate to 67%). This success rate of the thrombolytic therapy ranges within the limits given by literature. In five patients the authors evaluated the behaviour of the left ventricular asynergy (its range and index) prior to and following the thrombolytic therapy and this examination they consider to be appropriate for observance of the thrombolytic therapy success rate in patients with AMI.

    Design: Retrospective observational case-control study comparing patients with suspected acute myocardial infarction (AMI) treated with thrombolytic therapy in the prehospital environment with patients treated in hospital. Setting: Wyre Forest District and Worcestershire Royal Hospital, UK. Participants: (A) All patients who received prehospital thrombolytic therapy for suspected AMI accompanied by electrocardiographic features considered diagnostic. (B) Patients who received thrombolytic therapy after arrival at hospital for the same indication, matched with group A by age, gender and postcode. Main outcome measures: 1. Call to needle time 2. Percentage of patients treated within one hour of calling for medical help 3. Appropriateness of thrombolytic therapy 4. Safety of thrombolytic therapy Results: 1. The median call to needle time for patients treated before arriving in hospital (n = 27) was 40 minutes with an inter-quartile range 25–112 (mean 43 minutes). Patients from the same area who were treated in hospital (n = 27) had a median time of 106 minutes with an inter-quartile range 50–285 (mean 126 minutes). This represents a median time saved by prehospital treatment of 66 minutes. 2. 60 minutes after medical contact, 96 % of patients treated before arrival in hospital had received thrombolytic therapy; this compares with 4% of patients from similar areas treated in hospital. 3. Myocardial infarction was confirmed in 92% (25/27) of patients who received prehospital thrombolytic therapy and similarly 92% (25/27) of those given in-hospital thrombolytic therapy. 4. No major bleeding occurred in either group. Group A suffered fewer in-hospital deaths than group B (1 versus 4). Cardiogenic shock (3 patients) and ventricular arrhythmia (5 patients) were seen only in group B. Conclusion: Paramedic-delivered thrombolytic therapy can be delivered appropriately, safely, and effectively. Time gains are substantial and can meet the national targets for early

    Red blood cell (RBC) aggregation may contribute to occlusion of the coronary microcirculation during myocardial infarction. We studied the effect of thrombolytic therapy on RBC aggregation in patients with acute myocardial infarction (AMI). Compared with patients with myocardial infarction who did not receive thrombolytic therapy, those treated with systemic thrombolysis exhibited significantly reduced RBC aggregation, reduced plasma fibrinogen levels and increased plasma D-dimer levels. Using measurement of RBC aggregation in a standardized dextran-500 solution, reduction in RBC aggregation after thrombolysis was shown to be plasma dependent. Thrombolytic therapy had no direct effect on intrinsic RBC aggregability in patients with AMI. We conclude that thrombolytic therapy has rheologic consequences that may contribute to its overall efficacy. Inhibition of RBC aggregation by thrombolytic therapy may result from the degradation of fibrinogen, a key factor in the formation of RBC aggregates, and from the generation of fibrinogen degradation products capable of disaggregating RBCs.

    Sixty complications occurred during 138 courses of intraarterial thrombolytic therapy in 122 patients during a 5-year period. These complications were recorded and analyzed prospectively to identify underlying errors in management. There were 31 bleeding episodes, 15 vascular complications, and 14 other complications. Twelve of the bleeding episodes occurred at the puncture site, and 19 occurred at remote sites, accounting for six of the eight deaths in the series. Management errors were clearly identified in 27 of the 60 complications. The three following patterns of errors were recognized: (1) mismanagement of bleeding (12 instances), (2) wrong patient selection (nine instances), and (3) breach of the administration protocol (six instances). The group of 27 complications with underlying management errors included seven of the eight deaths in the present series. Efforts to prevent complications from thrombolytic therapy should concentrate on the specific patterns of management errors identified. This study indicates that low-dose intraarterial thrombolytic therapy is not a low-risk alternative to surgical intervention but should be viewed as a prelude or possible alternative to surgery in selected patients despite the risks involved.

    Thrombolytic therapy has become the treatment of choice for patients with acute myocardial infarction. Researchers are not yet able to identify patients with salvage of myocardium who are at risk for recurrent coronary events. Thus, a prospective trial was performed in 46 patients with myocardial infarction (28 anterior and 18 inferior) who received thrombolytic therapy to determine if early thallium tomography (4.7 days) using oral dipyridamole would identify more patients with residual ischemia than early symptom-limited exercise treadmill tests (5.5 days). There were no complications during the exercise treadmill tests or oral dipyridamole thallium tomography. Mean duration of exercise was 11 +/- 3 minutes and the peak heart rate was 126 beats/min. Thirteen patients had positive test results. After oral dipyridamole all patients had abnormal thallium uptake on the early images. Positive scans with partial filling in of the initial perfusion defects were evident in 34 patients. Angina developed in 13 patients and was easily reversed with intravenous aminophylline. Both symptom-limited exercise treadmill tests and thallium tomography using oral dipyridamole were safely performed early after myocardial infarction in patients receiving thrombolytic therapy. Thallium tomography identified more patients with residual ischemia than exercise treadmill tests (74 vs 28%). Further studies are required to determine whether the results of thallium tomography after oral dipyridamole can be used to optimize patient management and eliminate the need for coronary angiography in some patients.

    Background Long-term central venous catheters have improved the quality of care for patients with chronic illnesses, but are complicated by obstructions which can result in delay of treatment or catheter removal. Design and Methods This paper reviews thrombolytic treatment for catheter obstruction. Literature from Medline searches using the terms “central venous catheter”, “central venous access device” OR “central venous line” associated with the terms “obstruction”, “occlusion” OR “thrombolytic” was reviewed. Efficacy of thrombolytic therapy, central venous catheter clearance rates and time to clearance were assessed. Results Alteplase, one of the current therapies, clears 52% of obstructed catheters within 30 min with 86% overall clearance (after 2 doses, when necessary). However, newer medications may have higher efficacy or shorter time to clearance. Reteplase cleared 67–74% within 30–40 min and 95% of catheters overall. Occlusions were resolved in 70 and 83% of patients with one and 2 doses of tenecteplase, respectively. Recombinant urokinase cleared 60% of catheters at 30 min and 73% overall. Alfimeprase demonstrated rapid catheter clearance with resolution in 40% of subjects within 5 min, 60% within 30 min, and 80% within 2 h. Additionally, urokinase prophylaxis decreased the incidence of catheter occlusions from 16–68% in the control group to 4–23% in the treatment group; in some studies, rates of catheter infections were also decreased in the urokinase group. Conclusions Thrombolytic agents successfully clear central venous catheter occlusions in most cases. Newer agents may act more rapidly and effectively than currently utilized therapies, but randomized studies with direct comparisons of these agents are needed to determine optimal management for catheter obstruction.

    The aim of this study was to investigate the correlation between the ST-segment and T-wave patterns in predischarge electrocardiogram and patency of left anterior descending coronary artery in patients with a first anterior myocardial infarction (AMI). One hundred and fifty-six of 175 consecutive patients who were admitted to our clinic between January 2000 and September 2002 due to a first episode of transmural AMI and who received thrombolytic therapy were enrolled. Coronary angiography was performed by the Judkins method on the 6th-10th day after the acute infarction. The corrected TIMI frame count (CTFC) was estimated according to the previously described method. According to the combination of the ST-segment and T-wave morphology on the day (6-10) of cardiac catheterization, patients were classified into four groups: group A, ST elevation <0.1 mV and negative T waves; group B, ST elevation >or=0.1 mV and negative T waves; group C, ST elevation <0.1 mV and positive T waves; and group D, ST elevation >or=0.1 mV and positive T waves. Of the 99 patients with negative T waves, 47 (48%) had CTFC or=40-100, and 5 (5%) CTFC >100. Of the 57 patients with positive T waves, CTFC was or=40-100 in 11 (19%), and >100 in 15 (26%) ( P < 0.001). From the 76 patients with an isoelectric ST segment, 38 (50%) had CTFC or=40-100, and 1 (1%) CTFC >100. Of the 80 patients with an elevated ST segment, 23 (29%) had CTFC or=40-100, and 19 (23%) CTFC >100 ( P < 0.001). Use of the combination of two electrocardiographic parameters (ST segment and T waves) also indicated that there were significant differences between groups A and D, and groups B and D ( P < 0.001 and P < 0.05, respectively). Development of an isoelectric ST segment with negative T waves may indicate a

    Suppurative thrombophlebitis (Lemierre's syndrome) of the internal jugular vein is a rare and sometimes fatal complication. It commonly occurs from oropharyngeal infections, peripheral lines, complications from dental procedures, gingivitis, or central venous catheterizations. Empiric antibiotics are the initial treatment of choice followed by thrombolytics or surgical thrombectomy in refractory cases. We present a case of septic thrombophlebitis of the right internal jugular vein from a peripherally inserted central venous catheter. We also review the current percutaneous mechanical thrombectomy and thrombolytics therapies for such a rare disorder. Mechanical thrombectomy includes rotational thrombectomy or rheolytic therapies. Devices include the Amplatz thrombectomy device (Microvena), the Arrow-Trerotola Percutaneous thrombolytic device (Arrow), and the Cragg-Casteneda thrombolytic brush (Microtherapeutics). Rheolytic therapies include Angiojet, the Hydrolyzer, and the Oasis Thrombectomy System. Percutaneous mechanical thrombectomy techniques include rotational fragmentation, aspiration or suction thrombectomy, and hydrodynamic thrombectomy. AngioJet catheters may be used for percutaneous embolectomy in conjunction with pulse spray techniques, which instill thrombolytics locally. Thrombolytics include streptokinase, urokinase, and recombinant-tissue plasminogen activator. Mechanical thrombectomy combined with thrombolytics provide optimal treatment results secondary to their complementary effects. Therefore, patients who are refractory to standard medical therapy and considered poor surgical candidates may benefit from combined percutaneous mechanical thrombectomy with thrombolytics to achieve superior results if no contraindications exist for thrombolytics.

Retrospective analysis of the clinical records of patients with the discharge diagnosis of AMI, between May 1988 and December 1995. Intensive Cardiac Care Unit (UCIM-Medicina IV) of Santa Maria University Hospital, Lisbon, Portugal. 1319 patients, 958 men (73%) and 361 women, mean age 64 +/- 12 years. Thrombolytic therapy was administered in 391 patients (30%). Female patients received less thrombolytic therapy compared with male (17% vs. 34%; p < 0.001). Anterior wall infarction was more frequent (38%). Patients in Killip class I-II (77%) received more thrombolytic therapy than class III-IV (33% vs. 17%). The utilization rate of thrombolytic therapy increased from 25% in 1988 to 34% in 1995. Two major categories of patients were not treated with thrombolysis: 1) patients presented more than 12 hours after pain onset (38%); 2) patients without ST segment elevation or LBBB on the ECG presented (37%). Overall hospital mortality was 15.6%. The mortality in patients receiving thrombolytic therapy was significantly lower than in those excluded (9.4% vs. 18.2%; p < 0.001). Only 30% of patients with AMI receive TT. Of those excluded from this important therapeutic intervention, 75% had no ECG criteria or were outside the standard therapeutic "window". This significant group of patients need new diagnostic and intervention strategies.

    Appropriate management of pulmonary embolism patients with right ventricular dysfunction is uncertain. Recent guidelines have stressed the need for more data on the use of thrombolytic agents in the stable pulmonary embolism patient with right ventricular dysfunction. The objective of this study is to investigate the hypothesis that thrombolytic therapy in hemodynamically stable pulmonary embolism patients with right ventricular dysfunction is not associated with improved mortality. We did a retrospective analysis using multi-institutional observational data from the Nationwide Inpatient Sample database. International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes were used to identify the patients with pulmonary embolism and right ventricular dysfunction. In-hospital mortality was defined as the primary outcome of interest. Over the 4 years of the study period, 3668 patients with right ventricular dysfunction and pulmonary embolism were found, of which 3253 patients were identified as having hemodynamically stable right-sided heart failure with pulmonary embolism. There was no significant difference in mortality between hemodynamically stable pulmonary embolism patients with right ventricular dysfunction who received thrombolytic agents compared with those who did not. When outcomes were assessed for patients with right ventricular dysfunction and hemodynamic instability, a significant improvement in mortality was noted for patients with right ventricular dysfunction who received thrombolytic agents, which confirmed previous reports that thrombolytic therapy decreases mortality in pulmonary embolism patients who are hemodynamically unstable. Our data support the use of less aggressive treatment for stable pulmonary embolism patients with right ventricular dysfunction. These results argue against the reflexive use of thrombolytic agents in stable pulmonary embolism patients with right ventricular dysfunction. Copyright © 2016

    To determine whether utilization of emergency medical service (EMS) can increase use and expedite delivery of the thrombolytic therapy in acute ischemic stroke patients. We analyzed consecutive patients presenting to the emergency department (ED) with an ischemic stroke within 72 hours of symptom onset from a prospective stroke registry. Variables associated with early ED arrival (within 3 hours of stroke onset) and administration of intravenous thrombolytic therapy were analyzed. From January 1, 2010 to July 31, 2011, there were 1081 patients (62.3% men, age 69.6 ± 13 years) included in this study. Among them, 289 (26.7%) arrived in the ED within 3 hours, and 88 (8.1%) received thrombolytic therapy. Patients who arrived at the ED by EMS (n = 279, 25.8%) were independently associated with earlier ED arrival (adjusted odds ratio = 3.68, 95% confidence interval = 2.54-5.33), and higher chance of receiving thrombolytic therapy (adjusted odds ratio = 3.89, 95% confidence interval = 1.86-8.17). Furthermore, utilization of EMS significantly decreased onset-to-needle time by 26 minutes in patients receiving thrombolytic therapy. Utilization of EMS can not only help acute ischemic stroke patients in early presentation to ED, but also effectively facilitate thrombolytic therapy and shorten the onset-to-needle time.

    Thrombolytic therapy is a huge advance in the management of acute myocardial infarction (AMI). The results of large clinical trials over the past 9 years have unequivocally demonstrated its benefit: of every 1000 patients treated 30 will be saved, at a cost of two cases of nonfatal cerebral hemorrhage and seven of noncerebral major hemorrhage. The concurrent use of acetylsalicylic acid increases the benefit of thrombolytic therapy. Sales figures for thrombolytic agents indicate that their use in Canada is less than optimal and lags behind that in several European countries. Major educational efforts are needed to promote awareness of the efficacy of thrombolytic therapy and of optimal approaches for maximizing its potential benefit for patients with AMI. PMID:7697574

    Clinicians need to make decisions about the use of thrombolytic (fibrinolytic) therapy for pulmonary embolism (PE) after carefully considering the risks of major complications from bleeding, and the benefits of treatment, for each individual patient. They should probably not use systemic thrombolysis for PE patients with normal blood pressure. Treatment by human recombinant tissue plasminogen activator (rt-PA), alteplase, saves the lives of high-risk PE patients, that is, those with hypotension or in shock. Even in the absence of strong evidence, clinicians need to choose the most appropriate regimen for administering alteplase for individual patients, based on assessment of the urgency of the situation, risks for major complications from bleeding, and patient's body weight. In addition, invasive strategies should be considered when absolute contraindications for thrombolytic therapy exist, serious complications arise, or thrombolytic therapy fails.

    Data regarding thrombolytic treatment of right-sided mechanical valve thrombosis are almost nonexistent, and all current guidelines arise from very small case series. We retrospectively studied the in-hospital and long-term outcome data of a larger series of patients who had received, from September 2005 through June 2012, thrombolytic therapy for right-sided mechanical pulmonary valve or tricuspid valve thrombosis. We identified 16 patients aged 8–67 years who had undergone thrombolytic therapy for definite thrombotic mechanical valve obstruction in the tricuspid or pulmonary valve position (8 in each position). All study patients except one had subtherapeutic international normalized ratios. The 8 patients with pulmonary mechanical valve thrombosis had a 100% response rate to thrombolytic therapy, and their in-hospital survival rate was also 100%. The 8 patients with tricuspid mechanical valve thrombosis had a 75% response rate to thrombolytic therapy, with an in-hospital survival rate of 87.5%. The one-year survival rate for mechanical valve thrombosis treated with thrombolytic therapy (whether pulmonary or tricuspid) was 87.5%. On the basis of our data, we recommend that thrombolytic therapy remain the first-line therapy for right-sided mechanical valve thrombosis in adults or children—including children with complex congenital heart disease and patients with mechanical pulmonary valve thrombosis. Surgery should be reserved for patients in whom this treatment fails. PMID:26664307

    While the primary therapy for most patients with a pulmonary embolism (PE) consists of anticoagulation, the efficacy of thrombolysis relative to standard therapy remains unclear. In this retrospective cohort study of 15,944 patients with an objectively confirmed symptomatic acute PE, identified from the multicenter, international, prospective, Registro Informatizado de la Enfermedad TromboEmbólica (RIETE registry), we aimed to assess the association between thrombolytic therapy and all-cause mortality during the first 3 months after the diagnosis of a PE. After creating two subgroups, stratified by systolic blood pressure (SBP) (< 100 mm Hg vs. other), we used propensity score-matching for a comparison of patients who received thrombolysis to those who did not in each subgroup. Patients who received thrombolysis were younger, had fewer comorbid diseases and more signs of clinical severity compared with those who did not receive it. In the subgroup with systolic hypotension, analysis of propensity score-matched pairs (n = 94 pairs) showed a non-statistically significant but clinically relevant lower risk of death for thrombolysis compared with no thrombolysis (odds ratio [OR] 0.72; 95% confidence interval [CI], 0.36-1.46; P = 0.37). In the normotensive subgroup, analysis of propensity score-matched pairs (n = 217 pairs) showed a statistically significant and clinically meaningful increased risk of death for thrombolysis compared with no thrombolysis (OR 2.32; 95% CI, 1.15-4.68; P = 0.018). When we imputed data for missing values for echocardiography and troponin tests in the group of normotensive patients, we no longer detected the increased risk of death associated with thrombolytic therapy. In normotensive patients with acute symptomatic PE, thrombolytic therapy is associated with a higher risk of death than no thrombolytic therapy. In hemodynamically unstable patients, thrombolytic therapy is possibly associated with a lower risk of death than no thrombolytic

    In summary, a variety of nuclear techniques may be used to investigate the effects of thrombolytic therapy and myocardial reperfusion. Assessments of global and regional ventricular function, myocardial perfusion, and metabolic integrity are available and appear to add substantially to conventional assessment. Timing of studies appears to be critical. Complementary data can be obtained in both the acute and convalescent phase of myocardial infarction. 49 references.

    Diagnostic and interventional percutaneous coronary catheterization is associated with stroke. Many of such strokes are asymptomatic, but some are devastating. Once the diagnosis of acute cerebral infarction is confirmed, thrombolytic therapy should be administrated within the time window of 3 hours. We report a 61-year-old woman who suffered from an acute cerebral infarction during diagnostic cardiac catheterization for unstable angina, which manifested as sudden onset of global aphasia, right hemiplegia and gaze preponderance to the left side. Computed tomography of the head performed immediately after recognition of the symptoms showed a hyperdense middle cerebral artery (MCA) sign. Following prompt recognition and diagnosis, intravenous thrombolytic therapy was administered 2 hours after symptom onset. The patient had a favorable outcome. Initially, National Institutes of Health Stroke Scale score was 21, and 24 hours later it improved to 9. The hyperdense MCA lesion had resolved on the 24-hour follow-up scan. This case illustrates the clinical benefit of thrombolytic therapy in the setting of acute stroke associated with cardiac catheterization.

    Thrombolytic therapy activates the contact system, and factor XII activation may activate the coagulation cascade and inflammation. It is not known whether an early inflammatory response is induced by thrombolytic therapy in patients with acute myocardial infarction (AMI). We prospectively measured the plasma levels of activated factor XII, cleaved kininogen, prothrombin fragment 1 + 2 (as indexes of the contact phase and coagulation activation), and interleukin-6 and C-reactive protein (CRP) (as indexes of inflammation) in 39 patients hospitalized for AMI within 12 hours of symptom onset: 26 receiving thrombolytic therapy and 13 heparin alone. Blood samples were collected at baseline and after 90 minutes and 24 hours. Patients undergoing thrombolysis had a significant early increase in activated factor XII (from 2.2 ng/ml at baseline to 4.7 ng/ml after 90 minutes; p = 0.0001), cleaved kininogen (from 26% to 37%; p = 0.001), and fragment 1 + 2 (from 1.4 to 2.1 nmol/L; p = 0.0001), whereas the 24-hour levels were similar to baseline levels. The levels of interleukin-6 significantly increased during the first 90 minutes (from 3.9 to 6.3 microg/ml; p = 0.001), and were even higher after 24 hours (11.9 ng/ml, p = 0.0001). CRP levels increased only after 24 hours (p = 0.0001). There were no changes in these parameters in patients receiving heparin alone, except for a 24-hour increase in interleukin-6 and CRP levels. Thus, in patients with AMI receiving thrombolytic therapy, early activation of inflammation parallels the activation of the contact system and the coagulation cascade, which might contribute to microvascular obstruction and reperfusion injury.

    2012-01-01

    Background: Antithrombotic therapy in valvular disease is important to mitigate thromboembolism, but the hemorrhagic risk imposed must be considered. Methods: The methods of this guideline follow those described in Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines. Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines in this supplement. Results: In rheumatic mitral disease, we recommend vitamin K antagonist (VKA) therapy when the left atrial diameter is > 55 mm (Grade 2C) or when complicated by left atrial thrombus (Grade 1A). In candidates for percutaneous mitral valvotomy with left atrial thrombus, we recommend VKA therapy until thrombus resolution, and we recommend abandoning valvotomy if the thrombus fails to resolve (Grade 1A). In patients with patent foramen ovale (PFO) and stroke or transient ischemic attack, we recommend initial aspirin therapy (Grade 1B) and suggest substitution of VKA if recurrence (Grade 2C). In patients with cryptogenic stroke and DVT and a PFO, we recommend VKA therapy for 3 months (Grade 1B) and consideration of PFO closure (Grade 2C). We recommend against the use of anticoagulant (Grade 1C) and antiplatelet therapy (Grade 1B) for native valve endocarditis. We suggest holding VKA therapy until the patient is stabilized without neurologic complications for infective endocarditis of a prosthetic valve (Grade 2C). In the first 3 months after bioprosthetic valve implantation, we recommend aspirin for aortic valves (Grade 2C), the addition of clopidogrel to aspirin if the aortic valve is transcatheter (Grade 2C), and VKA therapy with a target international normalized ratio (INR) of 2.5 for mitral valves (Grade 2C). After 3 months, we suggest aspirin therapy (Grade 2C). We recommend early bridging of mechanical valve patients to VKA therapy with unfractionated heparin (DVT dosing) or low

    Objectives: This article provides recommendations on the use of antithrombotic therapy in patients with stroke or transient ischemic attack (TIA). Methods: We generated treatment recommendations (Grade 1) and suggestions (Grade 2) based on high (A), moderate (B), and low (C) quality evidence. Results: In patients with acute ischemic stroke, we recommend IV recombinant tissue plasminogen activator (r-tPA) if treatment can be initiated within 3 h (Grade 1A) or 4.5 h (Grade 2C) of symptom onset; we suggest intraarterial r-tPA in patients ineligible for IV tPA if treatment can be initiated within 6 h (Grade 2C); we suggest against the use of mechanical thrombectomy (Grade 2C) although carefully selected patients may choose this intervention; and we recommend early aspirin therapy at a dose of 160 to 325 mg (Grade 1A). In patients with acute stroke and restricted mobility, we suggest the use of prophylactic-dose heparin or intermittent pneumatic compression devices (Grade 2B) and suggest against the use of elastic compression stockings (Grade 2B). In patients with a history of noncardioembolic ischemic stroke or TIA, we recommend long-term treatment with aspirin (75-100 mg once daily), clopidogrel (75 mg once daily), aspirin/extended release dipyridamole (25 mg/200 mg bid), or cilostazol (100 mg bid) over no antiplatelet therapy (Grade 1A), oral anticoagulants (Grade 1B), the combination of clopidogrel plus aspirin (Grade 1B), or triflusal (Grade 2B). Of the recommended antiplatelet regimens, we suggest clopidogrel or aspirin/extended-release dipyridamole over aspirin (Grade 2B) or cilostazol (Grade 2C). In patients with a history of stroke or TIA and atrial fibrillation we recommend oral anticoagulation over no antithrombotic therapy, aspirin, and combination therapy with aspirin and clopidogrel (Grade 1B). Conclusions: These recommendations can help clinicians make evidence-based treatment decisions with their patients who have had strokes. PMID:22315273

    There is no prehospital stratification tool specifically for predicting thrombolytic therapy after transportation. We developed a new prehospital scale named the Maria Prehospital Stroke Scale (MPSS) by modifying the Cincinnati Prehospital Stroke Scale. Our objective is to evaluate its utility in a citywide bypass transportation protocol for intravenous (IV) tissue plasminogen activator (tPA). In the MPSS, facial droop, arm drift, and speech disturbance are tested by emergency medical technicians (EMTs). Facial droop is graded as normal (0) or abnormal (1), and the other 2 items are graded in 3 levels as normal (0), not severe (1), and severe (2). Thus, the total MPSS score ranges from 0 to 5. The predictive value of MPSS for thrombolytic therapy after bypass transportation was evaluated in 1057 patients. The MPSS scored by EMTs was significantly correlated with the National Institutes of Health Stroke Scale score in the emergency room (Spearman rho = .67, P = .000). The onset-to-door time was significantly longer with a low MPSS score (analysis of variance, F5,4.21 = .001). The rate of thrombolytic therapy was increased when the MPSS score increased from 0 to 5: 0%, 4.1%, 8.8%, 13.0%, 20.3%, and 31.5%, respectively. The areas under the receiver operating characteristic curve for the correct diagnosis of stroke and prediction of IV tPA therapy were calculated as .737 (95% confidence interval [CI]: .688-.786) and .689 (95% CI: .645-.732), respectively. Multivariate logistic regression analysis showed that the MPSS score and the detection-to-door time were independent predictors of tPA use after transportation. The MPSS is a novel prehospital stratification tool for the prediction of thrombolytic therapy after transportation. Copyright © 2013 National Stroke Association. Published by Elsevier Inc.

    Thrombolytic therapy rate for acute ischemic stroke remains low, and improving public awareness of thrombolytic therapy may be helpful to reduce delay and increase chances of thrombolytic therapy. Our purpose was to survey the level of knowledge about thrombolytic therapy for acute ischemic stroke among community residents in Yuzhong district, Chongqing, China. In 2011, a population-based face-to-face interview survey was conducted in Yuzhong district, Chongqing. A total of 1500 potential participants aged ≥18 years old were selected using a multi-stage sampling method. A total of 1101 participants completed the survey. Only 23.3% (95% CI = 20.8 to 25.8) were aware of thrombolytic therapy for acute ischemic stroke, of whom 59.9% (95% CI = 53.9 to 65.9) knew the time window. Awareness of thrombolytic therapy was higher among young people, those with higher levels of education and household income, those with health insurance, and those who knew all 5 stroke warning signs, while awareness of the time window was higher among those aged 75 years or older. Multivariate logistic regression analysis showed that awareness of thrombolytic therapy was independently associated with age, education level, health insurance and knowledge of stroke warning signs (P<0.05). In this population-based survey the community residents have poor awareness of thrombolytic therapy for acute ischemic stroke.

    The use of thrombolytic agents has greatly improved patient outcomes, but the prothrombotic response to these drugs in vivo is unknown. Approximately 24 h after we induced thrombosis in male Sprague–Dawley rats, we placed an infusion line in the inferior vena cava and administered either saline or a thrombolytic agent (tissue plasminogen activator [tPA] or plasmin) for 30 min. Blood was drawn immediately after infusion; rats were euthanized 24 h after infusion for collection of blood and tissue (inferior vena cava and thrombus). Thrombus size was decreased in the tPA-treated rats but not in those that received saline or plasmin; this change correlated with the significant rise in D-dimer levels noted immediately after infusion in the tPA-treated rats. Plasma soluble P-selectin, a prothrombotic marker, was elevated at 24 h in the plasmin group compared with the other treatment groups. There were no significant differences in plasma C3a, C5a, or C5b9 levels or in thrombus C3 levels between groups. According to ultrastructural analysis, thrombus structure and vein wall effects did not differ between groups. Local tPA did not induce a prothrombotic state during acute DVT or after thrombolytic therapy in a rodent model of venous thrombolysis. Conversely, levels of the prothrombotic marker plasma soluble P-selectin increased when plasmin was administered. PMID:23759527

    Background Ischemic cerebrovascular accidents remain a leading cause of morbidity and mortality. Thrombolytic therapy for acute ischemic stroke within 3 h of symptom onset of highly select patients has been advocated by some groups since 1995, but trials have yielded inconsistent outcomes. One recent trial demonstrated significant improvement when the therapeutic window was extended to 4.5 h. Clinical Question Does the intravenous systemic administration of tPA within 4.5 h to select patients with acute ischemic stroke improve functional outcomes? Evidence Review All randomized controlled trials enrolling patients within 4.5 h were identified, in addition to a meta-analysis of these trial data. Results The National Institute of Neurological Disorders and Stroke (NINDS) and European Cooperative Acute Stroke Study III (ECASS III) clinical trials demonstrated significantly improved outcomes at 3 months, with increased rates of intracranial hemorrhage, whereas ECASS II and the Acute Noninterventional Therapy in Ischemic Stroke (ATLANTIS) study showed increased hemorrhagic complications without improving outcomes. Meta-analysis of trial data from all ECASS trials, NINDS, and ATLANTIS suggest that thrombolysis within 4.5 h improves functional outcomes. Conclusion Ischemic stroke tPA treatment within 4.5 h seems to improve functional outcomes and increases symptomatic intracranial hemorrhage rates without significantly increas ing mortality.

    The increasing use of thrombolytic therapy following acute myocardial infarction has given rise to value for money questions. This study examines the cost-effectiveness of the thrombolytic agent anistreplase (Eminase). Using clinical trial data on the efficacy of anistreplase compared to placebo, and retrospectively obtained cost data from the National Health Service, the study estimates the cost per life-year saved of using this therapeutic agent. The results suggest that the cost-effectiveness of thrombolytic therapy compares favourably with that of other forms of coronary disease treatment. The study concludes that comparisons of the relative cost-effectiveness of different thrombolytic agents are an obvious next step, once full results from recent clinical trials are available.

  18. Role of myocardial perfusion imaging in evaluating thrombolytic therapy for acute myocardial infarction

    SciTech Connect

    Beller, G.A.

    1987-03-01

    Myocardial thallium-201 scintigraphy is being increasingly employed as a method for assessing the efficacy of coronary reperfusion in acute myocardial infarction. New thallium uptake after intracoronary tracer administration after successful recanalization indicates that nutrient blood flow has been successfully restored. One may also presume that some myocardial salvage occurred if thallium administered in this manner is transported intracellularly by myocytes with intact sarcolemmal membranes. However, if one injects thallium by way of the intracoronary route immediately after reperfusion, the initial uptake of thallium in reperfused myocardium may predominantly represent hyperemic flow and regional thallium counts measured may not be proportional to the mass of viable myocytes. When thallium is injected intravenously during the occlusion phase the degree of redistribution after thrombolysis is proportional to the degree of flow restoration and myocardial viability. When thallium is injected for the first time intravenously immediately after reperfusion, an overestimation of myocardial salvage may occur because of excess thallium uptake in the infarct zone consequent to significant hyperemia. Another approach to myocardial thallium scintigraphy in patients undergoing thrombolytic therapy is to administer two separate intravenous injections before and 24 hours or later after treatment. Finally, patients with acute myocardial infarction who receive intravenous thrombolytic therapy are candidates for predischarge exercise thallium-201 scintigraphy for risk stratification and detection of residual ischemia.

    The concept of telestroke networks has been proposed to overcome regional disparities in stroke treatment. Such networks do not yet operate in Japan. We aimed to determine the specific needs for telestroke networks and to estimate the effects on the number of thrombolytic therapies. Five of the 47 Japanese prefectures with various population densities to estimate the nationwide effect of telestroke networks were selected. The questionnaire survey was administered at hospitals in these prefectures that are authorized to admit patients with acute stroke. Low-volume hospitals that annually treated fewer than 12 patients with acute stroke had never used tissue plasminogen activator (tPA). The number of days when telestroke support might have been needed varied depending on the size of the population aged 65 years or older within a 30-minute-driving-time area of a hospital and the annual number of patients treated within 3 hours of onset. The geographic information system analysis showed that .6%-8.3% of the population lived in areas where they could not reach a hospital for acute stroke treatment within 60 minutes. If 24/7 full telestroke support was introduced to the existing hospitals, 6.8-69.3 more patients could be treated by intravenous (IV) tPA annually. These numbers exceeded the estimated annual increases of .8-13.7 more patients if a drip-and-ship telestroke network was introduced into an underserved area outside the 60-minute-driving-time area. This study uncovered that many Japanese stroke hospitals, especially low-volume facilities located in rural areas, do not perform IV tPA therapy in 24/7 fashion and telestroke support to these hospitals may be highly effective compared with the drip-and-ship network in an underserved area.

    1990-10-16

    Technetium-99m (Tc-99m) sestamibi has been used to evaluate the efficacy of thrombolytic therapy. Improved image quality due to the higher photon energy of Tc-99m and the increased allowable doses of this radiopharmaceutical along with its lack of redistribution makes Tc-99m sestamibi an acceptable imaging agent for such studies. This imaging agent was used for serial quantitative planar and tomographic imaging to assess the initial risk area of infarction, its change over time and the relation to infarct-related artery patency in patients with a first acute myocardial infarction. Twenty-three of 30 patients were treated with recombinant tissue-type plasminogen activator (rt-PA) within 4 hours after onset of acute chest pain. Seven patients were treated in the conventional manner and did not receive thrombolytic therapy. The initial area at risk varied greatly both in patients treated with rt-PA and in those who received conventional therapy. Patients with successful thrombolysis and patient infarct arteries had a significantly greater reduction of Tc-99m sestamibi defect size than patients who had persistent coronary occlusion. Serial imaging with Tc-99m sestamibi could find important application in future clinical research evaluating the efficacy of new thrombolytic agents. Direct measurements of the amount of hypoperfused myocardium before and after thrombolysis could provide rapid and unequivocal results using fewer patients and avoiding the use of mortality as an end point. This approach has not yet been widely tested in the clinical arena.

    Acute ST elevation myocardial infarction has high mortality and morbidity rates. The majority of patients with this condition face erectile dysfunction in addition to other health problems. In this study, we aimed to investigate the effects of two different reperfusion strategies, primary angioplasty and thrombolytic therapy, on the prevalence of erectile dysfunction after acute myocardial infarction. Of the 71 patients matching the selection criteria, 45 were treated with primary coronary angioplasty with stenting, and 26 were treated with thrombolytic agents. Erectile function was evaluated using the International Index of Erectile Function in the hospital to characterize each patient's sexual function before the acute myocardial infarction and 6 months after the event. The time required to restore blood flow to the artery affected by the infarct was found to be associated with the occurrence of erectile dysfunction after acute myocardial infarction. The increase in the prevalence of erectile dysfunction after acute myocardial infarction was 44.4% in the angioplasty group and 76.9% in the thrombolytic therapy group (P=0.008). In conclusion, this study has shown that reducing the time of reperfusion decreases the erectile dysfunction prevalence, and primary angioplasty is superior to thrombolytic therapy for decreasing the prevalence of erectile dysfunction after acute myocardial infarction.

    Background and Purpose Advances in the management of acute ischemic stroke and medical imaging are creating pressure to replace the rigid one-third middle cerebral artery (MCA) and non-contrast-enhanced CT (NCCT) Alberta Stroke Program Early CT Score (ASPECTS) thresholds used for the selection of patients eligible for intravenous thrombolytic therapy. The identification of potentially salvageable ischemic brain tissue lies at the core of this issue. In this study, the role of CT perfusion ASPECTS in the detection of reversible ischemia was analyzed. Materials and Methods We retrospectively reviewed the clinical and imaging data of 92 consecutive patients who received intravenous thrombolytic therapy for acute (duration <3 h) ischemic stroke. Most of the patients underwent admission multimodal CT, and all patients had follow-up NCCT at 24 h. ASPECTS was assigned to all modalities and correlated with clinical and imaging parameters. Receiver-operating characteristic curve analysis was performed to determine optimal thresholds for different parameters to predict clinical outcome. Results A perfusion defect could be detected in 50% of the patients. ASPECTS correlated inversely with the clinical outcome in the following order: follow-up NCCT > cerebral blood volume (CBV) > mean transit time (MTT) > admission NCCT. The follow-up NCCT and the CBV displayed a statistically significant difference from the admission NCCT, while the MTT did not reach statistical significance. The threshold that best differentiated between good and bad clinical outcome on admission was CBV ASPECTS ≥7. In patients with CT perfusion ASPECTS mismatch, MTT and CBV ASPECTS essentially provided the lower and upper limits for the follow-up NCCT ASPECTS, thus defining the spectrum of possible outcomes. Furthermore, CT perfusion ASPECTS mismatch strongly correlated (r = 0.83) with the mismatch between the tissue at risk and the final infarct, i.e. the amount of salvaged tissue. This finding suggests

    Abstract It remains unclear whether preexisting cerebral microbleeds (CMBs) increase the risks of worse functional outcome after thrombolytic therapy. We performed a systematic review and meta-analysis to assess the risk of unfavorable outcome in patients with acute ischemic stroke and CMBs. We searched EMBASE, PubMed, and Web of Science for relevant studies assessing functional outcome in the patients with CMBs following thrombolytic therapy. Fixed-effects and random-effects models were performed. Five eligible studies including 1974 patients were pooled in meta-analysis. The prevalence of CMBs was 24.3%. The pooled analysis demonstrates odds ratio for preexisting CMBs and the achievement of favorable outcome to be 0.69 (95% CI 0.56–0.86; P = 0.001) with no evidence of statistical heterogeneity (I2 = 46.7%, P = 0.112). Our meta-analysis of available published data demonstrates an increased risk of worse functional outcome after thrombolytic therapy for acute ischemic stroke in patients with pre-existing CMBs. Future studies are needed to determine whether the risk outweigh the expected benefit of reperfusion therapies. PMID:26717385

    Background Thrombolysis in acute submassive pulmonary embolism (PE) remains controversial. So we studied impact of thrombolytic therapy in acute submassive PE in terms of mortality, hemodynamic status, improvement in right ventricular function, and safety in terms of major and minor bleeding. Method A single-center, prospective, randomized study of 86 patients was conducted at LPS Institute of Cardiology, G.S.V.M. Medical College, Kanpur, India. Patients received thrombolysis (single bolus of tenecteplase) with unfractionated heparin (UFH, group I) or placebo with UFH (group II). Result Mean age of patients was 54.35 ± 12.8 years with male dominance (M:F = 70%:30%). Smoking was the most common risk factor seen in 29% of all patients, followed by recent history of immobilization (25%), history of surgery or major trauma within past 1 month (15%), dyslipidemia (10%) and diabetes mellitus (10%). Dyspnea was the most common symptom in 80% of all patients, followed by chest pain in 55% and syncope in 6%. Primary efficacy outcome occurred significantly better in group I vs. group II (4.5% vs. 20%; P = 0.04), and significant difference was also found in hemodynamic decompensation (4.5% vs. 20%; P = 0.04), the fall in mean pulmonary artery systolic pressure (PASP) (28.8% vs. 22.5%; P = 0.03), improvement in right ventricular (RV) function (70% vs. 40%; P = 0.001) and mean hospital stay (8.1 ± 2.5 vs. 11.1 ± 2.14 days; P = 0.001). There was no difference in mortality and major bleeding as safety outcome but increased minor bleeding occurred in group I patients (16% vs. 12%; P = 0.04). Conclusion Patients with acute submassive PE do not derive overall mortality benefit, recurrent PE and rehospitalization with thrombolytic therapy but had improved clinical outcome in form of decrease in hemodynamic decompensation, mean hospital stay, PASP and improvement of RV function with similar risk of major bleed but at cost of increased minor bleeding.

    During a recent one-year period, 44 clinical centers in the United States saw 2,539 patients with diagnoses of pulmonary embolism as supported by high probability lung scans and/or positive pulmonary angiograms. In developing proposals for a clinical trial of Thrombolysis in Pulmonary Embolism (TIPE), investigators in the 44 clinical centers reviewed the 2,539 patients' medical charts for contraindications to thrombolytic therapy. Overall, 1,345 (53.5%) patients surveyed in the TIPE clinical centers would have been acceptable for treatment with thrombolytic therapy, a proportion higher than generally anticipated. Risks of major blood loss were the most frequent contraindications to thrombolytic therapy and were found in 838 (33.3%) patients. Risks to the CNS were found to contraindicate thrombolytic therapy in 453 (17.9%) patients. Risks of bleeding into special compartments were found to contraindicate thrombolytic therapy in 76 (3.0%) patients. Pulmonary embolism is underdiagnosed in most clinical settings, and even more patients than found in the TIPE survey could benefit from appropriate diagnosis and treatment. The question remains as to whether pulmonary embolism patients will benefit from thrombolytic therapy. Only a randomized clinical trial will provide a satisfactory answer.

  6. Guidelines to reducing delays in administration of thrombolytic therapy in acute myocardial infarction.

    The thrombotic coronary accident that triggers a myocardial infarction initiates a 'wavefront' of ischaemic cell death that can be aborted by timely restoration of blood flow. Myocardium destined for necrosis can be salvaged by quick lysis of the culprit clot to restore perfusion, reduce infarct size and save lives. While a number of useful thrombolytic regimens have been investigated, the greatest barrier to optimising efficacy is reducing the delay between the onset of symptoms and administration of thrombolytic therapy. Clinical experience has confirmed laboratory evidence that prompt restoration of coronary blood flow can salvage more than 50% of ischaemic myocardium if achieved within 2 hours. However, after 6 hours of sustained ischaemia, the opportunity to achieve meaningful salvage is largely lost. Analysis of pooled data estimates that for each hour of delay 1.6 fewer lives are saved per 1000 patients treated. Other investigators have estimated 60 to 80 lives saved per 1000 patients treated within 1 hour of symptom onset. More realistically, the time from symptom onset to treatment averages 2.5 to 5 hours in various studies. Reluctance to seek medical help results in a delay of more than 4 hours in at least 40% of patients. There may be some benefits of late, time-independent reperfusion from 12 to 24 hours after symptoms. Some hibernating myocardium may be salvaged resulting in less adverse late ventricular remodelling, reduced infarction expansion and improved electrical stability. Barriers to timely thrombolytic treatment may be classified as presentation delay or treatment delay. Strategies to optimise timely treatment have included pre-hospital administration of thrombolytics. This achieves greatest benefit when used in a more rural setting where transportation times tend to be longer. In this setting, as much as 140 minutes has been shaved off the symptom-to-needle time with a 50% reduction in 3-month mortality sustained as a 30% reduction in 5-year

    We sought to determine the long-term cost-effectiveness of two reperfusion modalities in patients with acute ST-segment elevation myocardial infarction: primary percutaneous coronary intervention (PCI) versus thrombolytic therapy. A state-transition model that follows patients from when they develop STEMI until they die was developed. The model encompassed events and health states. Sensitivity analyses were undertaken. For a 65-year old man, life expectancy was 8.3 years with primary PCI and 7.6 years with thrombolytic therapy. The lifetime costs were 19,250 euros (NOK 154,000) and 29,250 euros (NOK 234,000), respectively, for patients living close to an invasive unit. Cost savings from PCI were mainly due to the reduction in future coronary interventions. For patients needing helicopter transport to arrive in time to an invasive unit for PCI, the costs were 24,000 euros (NOK 192,000) and 29,250 euros (NOK 234,000), respectively (all costs undiscounted). For women, the estimates were somewhat higher due to lower mortality. Compared with thrombolytic therapy, reperfusion by primary PCI results in greater health benefits at reduced lifetime costs. These findings may have important clinical implications in an increasing cost-conscious health care environment.

  8. Why emergency XeCT-CBF should become routine in acute ischemic stroke before thrombolytic therapy.

    Intravenous thrombolytic therapy using recombinant tissue plasminogen activator (rtpa) has been approved for the treatment of acute ischemic stroke in the USA, if treatment is initiated within 3-hours (NINDS tpa Stroke Study Group) but not 6 hours (ECASS II) after time of onset. Favorable outcome in the placebo arm was much higher than expected possibly because patients with TIA's are likely to be included as progressive ischemic stroke subjects when a brief 3-6 hours duration of stroke is defined as the therapeutic window. Yonas' group at the University of Pittsburg demonstrated that adding stable xenon inhalation to routine CT scanning performed during emergency screening of acute stroke, predicted which cases became irreversibly infarcted if thrombolytic therapy was not administered within a few hours of stroke onset, since non-contrasted CT scans are usually normal this early. Adding a few minutes for inhalation of 26% xenon is justified in order to measure LCBF values which predict size, severity and volumes of impending cerebral infarctions and rule out TIA's which have relatively normal CT-CBF values. CT-CBF measures provide positive indications for thrombolytic therapy. This is not possible by MRI and SPECT methods which are not sufficiently quantitative to discern LCBF values persistently below ischemic thresholds of 16 mls/100 gm/min, thereby predicting impending infarction.

    The use of thrombolytic agents in the treatment of hemodynamically stable patients with acute submassive pulmonary embolism (PTE) remains controversial. We, therefore, conducted this study to compare the effect of thrombolytic plus anticoagulation versus anticoagulation alone on early death and adverse outcome following submassive PTE. We conducted a study of patients with acute pulmonary embolism and pulmonary hypertension or right ventricular dilatation/dysfunction but without arterial hypotension or shock. The patients were randomly assigned in a single-blind fashion to receive an anticoagulant [Enoxaparin (1 mg/kg twice a day)] plus a thrombolytic [Alteplase (100 mg) or Streptokinase (1500000 u/2 hours)] or an anticoagulant [Enoxaparin (1 mg/kg twice a day)] alone. The primary endpoint was in-hospital death or clinical deterioration requiring an escalation of treatment. The secondary endpoints of the study were major bleeding, pulmonary hypertension, right ventricular dilatation at the end of the first week, and exertional dyspnea at the end of the first month. Of 50 patients enrolled, 25 patients were randomly assigned to receive an anticoagulant plus a thrombolytic and the other 25 patients were given an anticoagulant alone. The incidence of the primary endpoints was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.022). At the time of discharge, pulmonary artery pressure was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.018); however, reduction in the right ventricular size or normalization of the right ventricle showed non-significant differences between the two groups. There was no significant difference regarding the New York Heat Association (NYHA) functional class between the two groups at the end of the first month (p value = 0.213).

    Tools to predict the clinical response after intravenous thrombolytic therapy (tPA) are scarce. The iScore is an existing validated tool to estimate outcomes after an acute ischemic stroke. The purpose of this study was to determine the ability of the iScore to predict clinical response and risk of hemorrhagic transformation after tPA. We applied the iScore (www.sorcan.ca/iscore) to patients presenting with an acute ischemic stroke at 11 stroke centers in Ontario, Canada, between 2003 and 2009 identified from the Registry of the Canadian Stroke Network. A cohort of patients with stroke treated at 154 centers in Ontario was used for external validation. We compared outcomes between patients receiving and not receiving tPA after adjusting for differences in baseline characteristics using propensity-score matching. Patients were stratified into 3 a priori defined groups according to stroke severity using the iScore. Among 12 686 patients with an acute ischemic stroke, 1696 (13.4%) received intravenous thrombolysis. Higher iScores were associated with poor outcomes in both the tPA and non-tPA groups (P<0.001). Among those at low and medium risk based on their iScores, tPA use was associated with a benefit in the primary outcome (relative risk, 0.74 for those with low-risk iScores; 95% CI, 0.67-0.84; relative risk, 0.88 for those with medium risk iScores; 95% CI, 0.84-0.93). There was no difference in clinical outcomes between matched patients receiving and not receiving tPA in the highest iScore group (relative risk, 0.97; 95% CI, 0.94-1.01). Similar results were observed for disability at discharge and length of stay. The incident risk of neurological deterioration and hemorrhagic transformation (any or symptomatic) with tPA increased with the iScore risk. Results were similar in the validation cohort for risk of poor outcome with tPA by iScore level. The iScore may be used to predict clinical response and risk of hemorrhagic complications after tPA for an acute

    Background. Thrombolytic therapy (rt-PA) is approved for ischemic stroke presenting within 4.5 hours of symptoms onset. The rate of utilization of rt-PA is not well described in developing countries. Objectives. Our study examined patient characteristics and outcomes in addition to barriers to rt-PA utilization in a tertiary care center in Beirut, Lebanon. Methods. A retrospective chart review of all adult patients admitted to the emergency department during a one-year period (June 1st, 2009, to June 1st, 2010) with a final discharge diagnosis of ischemic stroke was completed. Descriptive analysis was done followed by a comparison of two groups (IV rt-PA and no IV rt-PA). Results. During the study period, 87 patients met the inclusion criteria and thus were included in the study. The mean age was found to be 71.9 years (SD = 11.8). Most patients arrived by private transport (85.1%). Weakness and loss of speech were the most common presenting signs (56.3%). Thirty-three patients (37.9%) presented within 4.5 hours of symptom onset. Nine patients (10.3%, 95% CI (5.5–18.5)) received rt-PA. The two groups (rt-PA versus non rt-PA) had similar outcomes (mortality, symptomatic intracerebral hemorrhage, modified Rankin scale scores, and residual deficit at hospital discharge). Conclusion. In our setting, rt-PA utilization was higher than expected. Delayed presentation was the main barrier to rt-PA administration. Public education regarding stroke is needed to decrease time from symptoms onset to ED presentation and potentially improve outcomes further. PMID:25140255

The men have higher cardiovascular basal risk. The average time of follow-up was 2.95±2.33 years. Incidence rate ratio (IR) shown higher risk in men than in women IR=3.2 (CI 95% 1.2-8.0). The dead cases were older (P=.032); with higher cardiovascular basal risk (P=.040) and more risk of stroke recurrence (P=<.001), with cardiovascular pathology before the stroke (P=.005); more stroke severity (P=.002); and a major fall in the score Barthel one year after the episode (P=.016). The percentage of deaths is significantly higher when the patient is referred by complications to other centres (P=.006) in relation to those referred to home, but just the gender (HR: 1,12; IC 95%: 1,05-1,20) and secondary cardiovascular prevention (HR: 0,13; IC 95%: 0,06-0,28) were associated with higher risk of mortality. After stroke episode treated with thrombolytic therapy, men have 12% higher risk of dying than women and don't be treated with secondary cardiovascular prevention rise 7.7 times the mortality risk.

    The precise time of using percutaneous coronary intervention (PCI) after fibrinolytic therapy for maximum efficiency and minimum side effects is still undetermined. Therefore, the present study was designed to compare the outcome of myocardial infarction (MI) patients who underwent surgical intervention (angiography and PCI) within 48 hours of thrombolytic therapy or after that. The present study is a prospective cohort study aiming to compare the occurrence of no-reflow phenomenon, unstable angina, bleeding during intervention, and one month major adverse cardiac outcomes (recurrent MI, need for repeating surgical intervention, and mortality) between MI patents undergoing surgical intervention within the first 48 hours of or after 48 hours of thrombolytic therapy. 90 patients with the mean age of 54.97 ± 10.54 were studied (86.67% male). 50 (56%) patients underwent surgical intervention within 48 hours and 40 (44%) after that. The 2 groups were not significantly different regarding baseline characteristics. No-reflow phenomenon in the < 48 hours group was about twice the > 48 hours group (OR = 0.35; 95% confidence interval: 0.14 - 0.92; p = 0.03), other outcomes were not significantly different. No case of mortality was seen in the 1 month follow up. Based on the results of the present study, it seems that no-reflow phenomenon rate is significantly lower in patients undergoing surgical intervention after 48 hours of fibrinolytic therapy. The difference between the two groups regarding prevalence of major adverse cardiac outcomes was not statistically significant.

    In 1933 Streptokinase (SK) was isolated from bacterial strains of haemolytic Streptococci. Since then it has become the widest spread drug for fibrinolysis. SK, a protein, consists of 415 aminoacids and has a molecular weight of 47,000u. Together with the plasminogen (PLG) of the blood it forms activator complexes, which then convert other PLG molecules of the blood to plasmin. Plasmin attacks and dissolves fibrin deposits. As a substance produced by bacteria SK stimulates antibody formation in the body, the titer will increase during therapy, and SK lysis should be terminated after 6 days of treatment. Usually SK is administered intravascularly to treat a wide range of diseases, associated with pathological activation of hemostasis, like deep vein thrombosis, pulmonary embolism, myocardial infarction etc.. Contraindications can be traced back to the effects of SK on coagulation and the immune system. Bleeding is the most common side effect, but also a few anaphylactic reactions, caused by massive antigen-antibody precipitation have been observed. The rate of lethality of the treatment was established at 0.7% of the cases. To reduce the incidence of side effects modifications of the drug have been proposed, such as activator complex, light B chain SK, and acylated activator therapy. Compared with Urokinase, SK shows a higher rate of side effects, especially in the field of the immune system. Therapy with Urokinase can be controlled more easily. Nevertheless because of considerable price differences and logistics, SK is preferred in Europe and the USA. If strict guidelines in therapeutic use are followed, the rate of side effects of the drug can be curtailed and will be comparable to those of Urokinase.

    Cardiac complications following stroke or acute cerebrovascular accidents (CVA) are common; however, many of these complications are asymptomatic and do not cause adverse cardiac effects. Symptomatic events (such as acute myocardial infarction after CVA) rarely occur and are often the result of an underlying cardiac embolic source, such as a left ventricular thrombus. We report a case of spontaneous coronary thrombosis following thrombolytic therapy for acute CVA, and discuss the implication that an underlying systemic pro-thrombotic state may predispose individuals to thrombosis in disparate vascular beds.

    In this study, we examined the relationship between PAI-1 4G/5G polymorphism and patency of the infarct-related artery after thrombolysis in patients with ST-elevation myocardial infarction (STEMI). Acute STEMI patients who received thrombolytic therapy within first 12 h were included in our study. The PAI-1 4G/5G promoter region insertion/deletion polymorphism was studied from venous blood samples. Patients with the PAI-1 4G/5G gene polymorphism were included in group 1 and the others were included in group 2. Coronary angiography was performed in all patients in the first 24 h after receiving thrombolytic therapy. Thrombolysis in myocardial infarction (TIMI) 0-1 flow in the infarct-related artery was considered as 'no flow', TIMI 2 flow as 'slow flow', and TIMI 3 flow as 'normal flow'. A total of 61 patients were included in our study. Thirty patients (49.2%) were positive for the PAI-1 4G/5G gene polymorphism, whereas 31 of them (50.8%) were in the control group. There were significantly more patients with 'no flow' (14 vs. 6; P=0.02) and less patients with 'normal flow' (8 vs. 19; P=0.02) in group 1. In addition, time to thrombolytic therapy (TTT) was maximum in the 'no flow' group and minimum in the 'normal flow' group (P=0.005). In the logistic regression analysis, TTT (odds ratio: 0.9898; 95% confidence interval: 0.982-0.997; P=0.004) and the PAI-1 4G/5G gene polymorphism (odds ratio: 4.621; 95% confidence interval: 1.399-15.268; P<0.01) were found to be independently associated with post-thrombolytic 'no flow'. The PAI-1 4G/5G gene polymorphism and TTT are associated independently with 'no flow' after thrombolysis in patients with STEMI.

    In order to further optimize the treatment strategy for the patients with acute basilar artery occlusion, we were dedicated to study the therapeutic effects and influential factors in the process of treated basilar artery occlusion with thrombolytic combined vascular interventional therapy. 75 patients with acute basilar artery occlusion treated with arterial thrombolytic therapy were analyzed retrospectively. In accordance with the discharge records of patients, their short-term curative effect with 24-hour treatment and 14-days treatment were evaluated. Our data showed that the survival condition of the patients with acute acute basilar artery occlusion were visibly improved by combination thrombolytic and interventional therapy. Moreover, their BI scores were remarkably improved, while NIHSS and mRS scores were evidently reduced. These data proved that our treatment strategy was able to improve the survival condition of patients with acute basilar artery occlusion. Furthermore, our data showed that coagulation related factors remarkably improved in the patients, when they treated by combination thrombolytic therapy with interventional therapy. In addition, our results suggested that the patients' bilateral Babinski(+), revascularization and coma symptom were closely related to their prognosis after treated the patients with combination thrombolytic and vascular interventional therapy, and the difference was statistically significant (p<0.05, p<0.05, p<0.05). Besides, our data also displayed that the with stent assisted angioplasty was significantly superior to the patients with balloon angioplasty, and the difference was statistically significant (p<0.05). Anyhow, combination thrombolytic with interventional therapy can effectively promote the prognosis of the patients with acute basilar artery occlusion. The coma symptom, bilateral Babinski(+), and revascularization in the patients with acute basilar artery occlusion have an appreciable impact on the patients

    This study examines the association between thrombolysis and visuoperceptual functions in right hemisphere (RH) infarct patients. Fifty-six consecutive patients with first acute RH infarct were matched for age, years of education and stroke severity at the time of admission to the emergency department (baseline NIHSS; National Institute of Health Stroke Scale), compared according to whether (T+) or not (T-) they received thrombolysis. Neurological (NIHSS at hospital ward; Barthel index; BI) and neuropsychological examinations were conducted 4 days after onset. Visuoconstructive abilities were assessed with the block design and visual search and reasoning with the picture completion subtests of the Wechsler Adult Intelligence Scale revised. Visual neglect was assessed with the conventional subtests of the Behavioural Inattention test and visual memory with the visual reproduction subtest of the Wechsler Memory Scale Revised. T+ and T- patients did not differ in baseline NIHSS, age, years of education, hemianopia, hemiparesis, or in basic ADL (BI). T- patients had more severe strokes (NIHSS at hospital ward) and poorer visuoconstructive abilities than T+ patients. Our results indicate that thrombolysis has a favourable effect on visuoperceptual functions in acute stroke.

    The aim of this study was to assess the benefits of telemedicine in the delivery of thrombolytic therapy for patients with acute ischemic stroke. We performed a meta-analysis using combinations of the following terms: telestroke, telemedicine, tissue plasminogen activator/t-PA, and acute ischemic stroke. The primary outcome was favorable outcome based on the modified Rankin score. Secondary outcomes were incidence of symptomatic intracranial hemorrhage and overall mortality. We found no significant difference in favorable outcome between the telemedicine and control groups, and no significant difference was found between these groups in the rate of symptomatic intracranial hemorrhage or overall mortality. Patients with acute ischemic stroke who were treated with intravenous thrombolysis had similar outcomes regardless of whether telemedicine was used or they were treated in-person at a medical facility. Telemedicine can be used to support hospitals with limited experience in administering thrombolytic therapy for stroke. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Today, there is an enormous amount of excitement in the field of stroke victim care due to the recent success of MR. CLEAN, SWIFT PRIME, ESCAPE, EXTEND-IA, and REVASCAT endovascular trials. Successful intravenous (IV) recombinant tissue plasminogen activation (rt-PA) clinical trials [i.e.: National Institutes of Neurodegenerative Disease and Stroke (NINDS) stroke trial; Third European Cooperative Acute Stroke Study (ECASSIII) and Third International Stroke study (IST-3)] also need to be emphasized. In the recent endovascular and thrombolytic trials, there is statistically significant improvement using both the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Score (mRS) scale, but neither approach promotes complete recovery in patients enrolled within any particular NIHSS or mRS score tier. Absolute improvement (mRS 0–2 at 90 days) with endovascular therapy is 13.5–31%, whereas thrombolytics alone also significantly improve patient functional independence, but to a lesser degree (NINDS rt-PA trial 13%). This article has 3 main goals: (1) first to emphasize the utility and cost-effectiveness of rt-PA to treat stroke; (2) second to review the recent endovascular trials with respect to efficacy, safety and cost-effectiveness as a stroke treatment; and (3) to further consider and evaluate strategies to develop novel neuroprotective drugs. A thesis will be put forth so that future stroke trials and therapy development can optimally promote recovery so that stroke victims can return to “normal” life. PMID:26314402

  4. Biological standards for potency assignment to fibrinolytic agents used in thrombolytic therapy.

    PubMed

    2014-03-01

    Thrombolytic drugs are used for the treatment of thrombotic disorders such as acute myocardial infarction, acute ischemic stroke, and pulmonary embolism. Biological standards are used for potency assignment to the range of fibrinolytic proteins used in thrombolytic therapy. The World Health Organization (WHO) International Standards are primary reference materials, calibrated in arbitrary units (international unit), assigned by collaborative study using the range of assay methods available at the time. Provided the standard and test material are equivalent, adhering to the principle of measuring like versus like, the exact nature of the assay method is unimportant. This approach has been applied successfully for several decades since the advent of fibrinolytic treatment, ensuring consistency for potency labeling and the correct dosing of patients. The emergence of generic biosimilar products and new recombinant variants poses a challenge to this system, where functional differences impact on the relative biological activity in different assay systems. A more demanding system of standardization may therefore be required on the basis of international reference materials with associated reference methods. WHO recognizes this, and where possible and practical is seeking to incorporate concepts of traceability, uncertainty, and commutability to International Standards. However, some caution is needed because limitations on the characterization of many complex biologicals remain real, and a flexible approach is required on the basis of real-world needs.

    Introduction: The precise time of using percutaneous coronary intervention (PCI) after fibrinolytic therapy for maximum efficiency and minimum side effects is still undetermined. Therefore, the present study was designed to compare the outcome of myocardial infarction (MI) patients who underwent surgical intervention (angiography and PCI) within 48 hours of thrombolytic therapy or after that. Methods: The present study is a prospective cohort study aiming to compare the occurrence of no-reflow phenomenon, unstable angina, bleeding during intervention, and one month major adverse cardiac outcomes (recurrent MI, need for repeating surgical intervention, and mortality) between MI patents undergoing surgical intervention within the first 48 hours of or after 48 hours of thrombolytic therapy. Results: 90 patients with the mean age of 54.97 ± 10.54 were studied (86.67% male). 50 (56%) patients underwent surgical intervention within 48 hours and 40 (44%) after that. The 2 groups were not significantly different regarding baseline characteristics. No-reflow phenomenon in the < 48 hours group was about twice the > 48 hours group (OR = 0.35; 95% confidence interval: 0.14 – 0.92; p = 0.03), other outcomes were not significantly different. No case of mortality was seen in the 1 month follow up. Conclusion: Based on the results of the present study, it seems that no-reflow phenomenon rate is significantly lower in patients undergoing surgical intervention after 48 hours of fibrinolytic therapy. The difference between the two groups regarding prevalence of major adverse cardiac outcomes was not statistically significant. PMID:28286839

    To assess the efficacy of thrombolytic therapy combined with Chinese herbal medicine (CHM) in treating acute myocardial infarction (AMI). One hundred and one cases of AMI were divided randomly into two groups. The treated group treated with thrombolytic therapy combined with CHM and the control group treated with thrombolytic therapy alone. The criteria of patency of coronary artery were conducted according to the referential standard of thrombolytic therapy in treating AMI introduced by Chinese Angiocardiopathy Medical Journal, 1991. The patency rate of coronary artery of the two groups were 68.63% and 56.00%, the four-week mortality 3.92% and 10.00%, hemorrhage occurrence 1.96% and 10.00%, congestive heart failure occurrence 5.88% and 16.00%, severe arrhythmia occurrence 11.76% and 22.00%, and the shock occurrence 3.92% and 8.00% respectively. The difference between the two groups was significant, P < 0.01, P < 0.05. The effect of the treated group was better and the complication occurrence of the treated group was lower than those of the control group.

    Abstract Renal dysfunction is a prevalent comorbidity in acute ischemic stroke patients requiring thrombolytic therapy. However, the effect of renal dysfunction on the clinical outcome of this population remains controversial. This study aimed to evaluate the safety and effectiveness of thrombolytic therapy in acute stroke patients with renal dysfunction using a meta-analysis. We systematically searched PubMed and EMBASE for studies that evaluated the relationship between renal dysfunction and intravenous tissue plasminogen activator (tPA) in patients with acute ischemic stroke. Poor outcome (modified Rankin Scale ≥2), mortality, and symptomatic intracranial hemorrhage (ICH) and any ICH were analyzed. Fourteen studies were included (N = 53,553 patients). The mean age ranged from 66 to 75 years. The proportion of male participants was 49% to 74%. The proportion of renal dysfunction varied from 21.9% to 83% according to different definitions. Based on 9 studies with a total of 7796 patients, the meta-analysis did not identify a significant difference in the odds of poor outcome (odds ratio [OR] = 1.06; 95% confidence interval [CI]: 0.96–1.16; I2 = 44.5) between patients with renal dysfunction and those without renal dysfunction. Patients with renal dysfunction were more likely to die after intravenous thrombolysis (OR = 1.13; 95% CI: 1.05–1.21; I2 = 70.3). No association was observed between symptomatic ICH (OR = 1.02; 95% CI: 0.94–1.10; I2 = 0) and any ICH (OR = 1.07; 95% CI: 0.96–1.18; I2 = 25.8). Renal dysfunction does not increase the risk of poor outcome and ICH after stroke thrombolysis. Renal dysfunction should not be a contraindication for administration of intravenous thrombolysis to eligible patients. PMID:25526464

    Pulmonary embolism (PE) is a major cause of morbidity and mortality world-wide, and the use of thrombolytic therapy has been associated with favourable clinical outcomes in certain patient subsets. These potential benefits are counterbalanced by the risk of bleeding complications, the most devastating of which is intracranial haemorrhage (ICH). We retrospectively evaluated 9703 patients from the 2003-2012 nationwide in-patient sample database (NIS) who received thrombolytics for PE. All patients with ICH during the PE hospitalisation were identified and a clinical risk score model was developed utilizing demographics and comorbidities. The dataset was divided 1:1 into derivation and validation cohorts. During 2003-2012, 176/9705 (1.8 %) patients with PE experienced ICH after thrombolytic use. Four independent prognostic factors were identified in a backward logistic regression model, and each was assigned a number of points proportional to its regression coefficient: pre-existing Peripheral vascular disease (1 point), age greater than 65 years (Elderly) (1 point), prior Cerebrovascular accident with residual deficit (5 points), and prior myocardial infarction (Heart attack) (1 point). In the derivation cohort, scores of 0, 1, 2 and ≥ 5 points were associated with ICH risks of 1.2 %, 1.9 %, 2.4 % and 17.8 %, respectively. Rates of ICH were similar in the validation cohort. The C-statistic for the risk score was 0.65 (0.61-0.70) in the derivation cohort and 0.66 (0.60-0.72) in the validation cohort. A novel risk score, derived from simple clinical historical elements was developed to predict ICH in PE patients treated with thrombolytics.

    Objectives: Intravenous thrombolytic therapy has established acceptable results in treating ischemic stroke. However, there is little information on treatment outcome especially in different subtypes. The aim of current study was to evaluate early and intermediate prognosis in intravenous thrombolytic therapy for acute ischemic stroke subtypes. Methodology: Forty eligible patients (57.5% male with mean age of 63.18±13.49 years) with definite ischemic stroke who were admitted to emergency department of Imam Reza University Hospital, in the first 180 minutes after occurrence received recombinant tissue plasminogen activator. All investigation findings were recorded and stroke subtypes were determined according to the Causative Classification of Stroke System. Stroke severity forms including modified Rankin Scale (mRS) and National Institutes of Health Stroke Scale (NIHSS) scores were recorded for all patients in first, seven and 90 days after stroke and disease outcome was evaluated. Results: The etiology of stroke was large artery atherosclerosis in 20%, cardio-aortic embolism in 45%, small artery occlusion in 17.5% and undetermined causes in 17.5%. NIHSS and mRS scores were significantly improved during time (P < 0.001 in both cases). Three months mortality rate was 25%. Among the etiologies, patients with small artery occlusion and then cardio-aortic embolism had lower NIHSS score at arrival (P = 0.04). Caplan-meier analysis showed that age, sex and symptom to needle time could predict disease outcome. Conclusion: Intravenous thrombolytic therapy is accompanied by good early and intermediate outcome in most patients with ischemic stroke. Small artery occlusion subtype had less disease severity and higher improvement. PMID:24353536

    To investigate prospectively the occurrence and significance of postinfarction transient left ventricular dysfunction, 33 ambulatory patients who underwent thrombolytic therapy after myocardial infarction were monitored continuously for 187 +/- 56 min during normal activity with a radionuclide left ventricular function detector at the time of hospital discharge. Twelve patients demonstrated 19 episodes of transient left ventricular dysfunction (greater than 0.05 decrease in ejection fraction, lasting greater than or equal to 1 min), with no change in heart rate. Only two episodes in one patient were associated with chest pain and electrocardiographic changes. The baseline ejection fraction was 0.52 +/- 0.12 in patients with transient left ventricular dysfunction and 0.51 +/- 0.13 in patients without dysfunction (p = NS). At follow-up study (19.2 +/- 5.4 months), cardiac events (unstable angina, myocardial infarction or death) occurred in 8 of 12 patients with but in only 3 of 21 patients without transient left ventricular dysfunction (p less than 0.01). During submaximal supine bicycle exercise, only two patients demonstrated a decrease in ejection fraction greater than or equal to 0.05 at peak exercise; neither had a subsequent cardiac event. These data suggest that transient episodes of silent left ventricular dysfunction at hospital discharge in patients treated with thrombolysis after myocardial infarction are common and associated with a poor outcome. Continuous left ventricular function monitoring during normal activity may provide prognostic information not available from submaximal exercise test results.

Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Systemic lupus erythematosus and secondary antiphospholipid (APS) was confirmed. The patient had headache that continued several days after cesarean section, therefore, brain magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) were performed, and cerebral vein thrombosis was documented. Distal segment of right lateral sinus and sigmoid sinus were not appeared in brain MRV. Abnormal hypersignal intensity of right lateral sinus/coronal T2 was detected. Thrombolytic therapy with 20 mg tissue plasminogen activator on right sigmoid and transverse sinus was performed by an interventional neurologist. After this procedure, the patient(')s headache healed and she was discharged in a good condition.

    Mismatch between clinical deficits and imaging lesions in acute stroke has been proposed as a method of identifying patients who have hypoperfused but still have viable brain, and may be especially apt to respond to reperfusion therapy. We explored this hypothesis using a combined database including 4 major clinical trials of intravenous (IV) thrombolytic therapy. To determine what the radiological correlates of a "matched" functional deficit are, we calculated the relationship between the ASPECT score of the 24-hour (follow-up) CT scan and the 24-hour National Institutes of Health Stroke Scale (NIHSS) score on the subsample with ASPECT scores performed at this time (n=820). Based on this empirical relationship, we computed the absolute difference between the observed baseline ASPECT score and the "expected" score (ie, matched) based on baseline NIHSS for all patients (n=2131). We tested whether patients with better than expected baseline ASPECTS were more likely to benefit from IV recombinant tissue plasminogen activation (rtPA). At 24 hours, there was a strong, linear, negative correlation between NIHSS and ASPECTS (r2=0.33, P<0.0001); on average, an increase of 10 points on NIHSS corresponded to a decrease of approximately 3 points on ASPECTS. At baseline, the average degree of mismatch between the observed and "expected" ASPECTS was 2.1 points (interquartile range, 1.0 to 3.4). However, multiple analyses failed to reveal a consistent relationship between the degree of clinical-CT mismatch at baseline and a patient's likelihood of benefiting from IV rtPA. Clinical-CT mismatch using ASPECT scoring does not reliably identify patients more or less likely to benefit from IV rtPA.

    Systemic thrombolytic therapy (STLT) is an available method of treatment of ischemic stroke (II) with proven efficacy. The efficacy and safety of STLT in certain groups of patients, in particular with diabetes mellitus type 2 (T2DM), are being discussed. To compare the efficacy and safety of STLC in II patients with T2DM, hyperglycemia and normoglycemia. Eighty-six patients were examined, including 23 with T2DM (7 newly diagnosed), 27 with hyperglycemia at stroke onset and 36 with normoglycemia. Cardioembolic subtype of II was diagnosed in 35%, atherothrombotic in 29%, lacunar in 7%. In other patients, the subtype was unknown. STLT was administered to all patients 153.8±4.7 min after stroke onset. At admission, the NIHSS severity of II and the level disability assessed by the Rankin scale did not differ in the three groups. A significantly lower regression was observed in patients with T2DM (p<0.01) in the 28th day. The fatality was higher in this group compared to the patients with normoglycemia (p<0.05). The frequency of symptomatic hemorrhagic transformation (SHT) was higher (56.5%) as well. After treatment, status of surviving patients in all groups has improved to the end of hospitalization, which was reflected in a significant decrease in NIHSS compared to baseline (p<0.01). The data indicate an increased risk of SGT after STLC in patients with T2DM. Significant positive changes in the surviving patients with T2DM confirm the feasibility of STLC in patients with T2DM.

    BACKGROUND: Coronary artery diseases are one of the causes of early death all over the world. In developed countries, ischemic heart disease is responsible for half of the entire mortalities; however in developing countries it is estimated that from 9 million deaths per year, 32 percent are due to coronary artery disease. Acute coronary syndromes are responsible for over 250,000 deaths per year caused by progressive atherosclerotic process which would lead to rupture of the atherosclerotic plaque and establishing thrombosis. This study aimed to determine time intervals between the onset of the heart attack symptoms to thrombolytic therapy in patients with ST segment elevation myocardial infarction (STEMI) in selected hospitals of Isfahan University of Medical Sciences. METHODS: In this study, 180 subjects with first time STEMI were enrolled by categorized random sampling in cardiac care units of four hospitals affiliated to Isfahan University of Medical Sciences during 9 months. Necessary information were collected by asking the patients and reviewing their records. The data included demographic, prehospital and in-hospital data of the patients. RESULTS: The mean duration of time interval from the onset of heart attack symptoms to the first action in order to seek medical care was 01:16’(01:36’) (h:m [SD]), from the symptoms onset to admission in emergency unit was 02:29’(02:00’) and from admission in emergency unit to administration of thrombolytic drug was 01:04’(01:14’). CONCLUSIONS: Time interval between onset of the acute coronary symptoms and seek for medical care and arrival to the emergency unit in this study had a better condition than other studies, but the interval between the emergency admission and thrombolytic therapy was longer than other studies.

    OBJECTIVE--To compare the activity of plasminogen activator inhibitor (PAI-1) in diabetic and non-diabetic patients admitted with acute myocardial infarction and to determine whether PAI-1 activity influences reperfusion after thrombolytic therapy. DESIGN--Prospective study of patients admitted with acute myocardial infarction. SETTING--District general hospital. MAIN OUTCOME MEASURES--Reperfusion assessed by time to peak release of creatine kinase-MB isoenzyme. RESULTS--Baseline PAI-1 activity and antigen concentrations were significantly higher in diabetic patients (n = 45) than in non-diabetic patients (n = 110) (24.6 (6.9) v 18.6 (7.9) AU/ml (AU = arbitrary units) (p = 0.0001) and 58.8 (13.1-328.8) v 41.0 (10.9-125.4) ng/ml (p = 0.004). Time to peak release of creatine kinase-MB was calculated in 123 (80%) patients. In 98 who received thrombolytic therapy the median time to peak enzyme release was 15.5 h (7.5-24 h) in diabetic patients (n = 26) and 12 h (5-26 h) in non-diabetic patients (n = 72) (p = 0.005). In those with a time to peak release of < or = 12 h, indicating likely successful reperfusion, PAI-1 activity was 17.5 (7.8) AU/ml compared with 22.8 (7.7) AU/ml in those with a time to peak release of > 12 h (p = 0.001). In multiple regression analysis both diabetes (p = 0.0001) and PAI-1 activity at admission (p = 0.029) were independently related to successful reperfusion. In 13 patients with evidence of reinfarction in hospital PAI-1 activity on day 3 was 26.7 (6.4) AU/ml compared with 21.7 (6.3) AU/ml in those without evidence of reinfarction (p = 0.032). CONCLUSION--Both raised PAI-1 activity on admission and diabetes were associated with a reduced likelihood of enzymatic evidence of reperfusion after thrombolytic therapy. Increased PAI-1 activity on day 3 was associated with an increased risk of reinfarction. Diabetic patients had higher PAI-1 activity on admission. This may partly explain their reduced likelihood of reperfusion. PMID:8280517

    Targeted delivery of thrombolytic drug to the site of emboli exhibits potential to greatly reduce hemorrhagic side effect. A rat embolic model with an easy access of a magnet was established for study of the efficacy of magnetic drug targeting. In anesthetized rats, a whole blood clot produced in vitro was injected from the right iliac artery and lodged in the left iliac artery. Intra-arterial infusion of recombinant tissue plasminogen activator (rt-PA) thereafter significantly reversed the iliac flow within 15 min. Placement of an NdFeB magnet above the left iliac artery caused magnetic nanoparticle retention against hemodynamic dragging force in the presence and absence of the clot. Our results suggest the feasibility of this rat embolic model for the study of magnetic targeted delivery of thrombolytic drugs.

    A 51-year-old male patient with circulatory arrest and ventricular fibrillation was brought to the emergency department after restoration of spontaneous circulation. ECG presented signs of acute anterolateral myocardial infarction. Thrombolytic therapy according to the Neuhaus scheme was initiated. After administration of 60 mg rt-PA continuously increasing protrusion and hyposphagma of both eyes (left > right) and left-sided monocle-hematoma was observed. CCT showed shadowing of sinus ethmoidales frontales, broadening of the left lateral rectus muscle and retrobulbar volume increase without any signs of recent bleeding. The ophthalmologist had to answer the question if there was, in spite of the massive retrobulbar volume increase, a sufficient blood supply for both eyes. Ophthalmoscopically there were no signs of intraretinal bleeding or retinal ischemia. Intraocular circulation was checked by color Doppler sonography: Ophthalmic artery, the short posterior ciliary arteries and central retinal artery of both eyes showed very low, but definitely positive bloodflow. Further course showed a constant trend towards higher systolic bloodflow velocities in all eye vessels, verified by color Doppler sonography. Computer perimetry, performed after the recovery of the patient, revealed a visual field defect, which was related to a breakdown of the flow in a ciliary artery rather than to damage due to compression of the optic nerve. Possible reasons of the retrobulbar volume increase under thrombolytic therapy are discussed.

    Kidneys from donors after cardiac death (DCD) are at risk for inferior outcomes, possibly due to microthrombi and additional warm ischemia. We describe an organ procurement organization-wide trial utilizing thrombolytic tissue plasminogen activator (tPA) during machine pulsatile perfusion (MPP). A kidney from each recovered kidney pair was prospectively randomized to receive tPA (50 mg Alteplase) or no tPA (control) in the MPP perfusate. From 2011 to 2013, 24 kidneys were placed with enrolled recipients from 19 DCD kidney donors. There were no significant differences for absolute values of flow or resistance while undergoing MPP between the groups, nor rates of achieving discrete flow and resistance targets. While there was a trend toward lower creatinine and higher glomerular filtration rates in the tPA group at 3, 6, 9, and 12 months, these differences were not significant. Delayed graft function (DGF) rates were 41.7% in the tPA group vs. 58.4% in the control group (OR 0.51, 95%CI 0.10-2.59, p = 0.68). Death-censored graft survival was similar between the groups. In this pilot study, encouraging trends are seen in kidney allograft function independent of MPP parameters following DCD kidney transplantation for those kidneys receiving thrombolytic tPA and MPP, compared with standard MPP. © 2015 John Wiley & Sons A/S.

    In the ALIAS (Albumin in Acute Stroke) Part 2 Multicenter Trial, 85% of subjects received standard-of-care intravenous tissue plasminogen activator, and 21% received some form of endovascular thrombolysis. The overall rate of symptomatic intracranial hemorrhage was within the expected range but was higher in albumin-treated subjects than in saline-treated subjects. Using the trial's Public Use Dataset, we analyzed factors contributing to symptomatic and asymptomatic intracranial hemorrhage in the 'safety sample' of 830 subjects. Four hundred sixteen subjects received albumin therapy, and 414 received saline. Intravenous tissue plasminogen activator was given to 68.2%; intravenous tissue plasminogen activator plus endovascular intervention in 16.4%; and endovascular therapy alone in 43%. Symptomatic intracranial hemorrhage occurred in 41 subjects - within the first 12 h in one-third of cases, and within the first day in ∼60%. Intravenous tissue plasminogen activator had been used in 78% of symptomatic intracranial hemorrhage subjects - no higher than in the overall cohort. In contrast, 48.8% of subjects with symptomatic intracranial hemorrhage had received endovascular therapy - a rate markedly higher than the 20.7% rate for the entire cohort (P = 0.0001). Sixty-eight point three percent of subjects with symptomatic intracranial hemorrhage had received albumin, and 31.7% saline (risk ratio 2.14, P = 0.025). Other factors associated with symptomatic intracranial hemorrhage were baseline NIHSS and ASPECTS scores and the SEDAN score. Forty-one point four percent of subjects with symptomatic intracranial hemorrhage died. The odds ratio for symptomatic intracranial hemorrhage was 3.89 (95% confidence interval 2.04-7.41) with endovascular therapy and 2.15 (confidence interval 1.08-4.25) with albumin. Endovascular thrombolysis was the major factor predisposing to symptomatic intracranial hemorrhage, and albumin contributed to this predisposition. The latter may

    The authors give an account of factors which influence left ventricular function after thrombolytic treatment of an occluded coronary artery. They found that improvement of left ventricular function following a three-week interval after recanalization of the artery the occlusion of which led to myocardial infarction, depends on the size of the necrotic focus. Improvement of global left ventricular function and above all of the regional function of the infarction segment can be expected if the size of the focus is such that less than 40 gram-equivalent of total creatine kinase are liberated from it.

    A 18-year-old man presented at our clinic with pain in the right flank following a motorbike accident. The diagnosis of renal artery dissection followed by thrombosis was made by computed tomography and confirmed by angiography. Successful revascularization was performed by means of repeated transcatheter injection of small doses of thrombolytic agents within the vessel, followed by deployment of a self-expandable stent. There were no complications, and the patient recovered well. Six months after stent placement, a selective renal angiogram showed excellent flow through the stented portion of the artery and normal parenchyma enhancement in the right kidney.

    The safety and efficacy of alteplase for ischemic stroke has not been examined in Chinese patients. We assessed the safety and efficacy of alteplase for acute ischemic stroke in daily clinical practice in Taiwan. A prospective, multicenter, observational study was conducted in Taiwan from December 2004 to July 2008. Eligible patients (241) receiving alteplase were recruited and divided into 2 groups: standard dose (0.90 + or - 0.02 mg/kg, n=125) and lower dose (0.72 + or - 0.07 mg/kg, n=116). Primary outcome measures were safety: symptomatic intracerebral hemorrhage and death within 3 months. The secondary outcome measure was efficacy a modified Rankin scale of 0 to 2 after 3 months. The standard-dose group had higher rates of symptomatic intracerebral hemorrhage using National Institute of Neurological Diseases and Stroke, European Cooperative Acute Stroke Study, and Safe Implementation of Thrombolysis in Stroke-Monitoring Study definitions (10.4% versus 5.2%, 8.0% versus 2.6%, and 5.6% versus 1.7%, respectively) and mortality within 3 months (12.8% versus 6.9%), twice that of the lower-dose group. This pattern was more prominent in older patients. Significantly higher rates of symptomatic intracerebral hemorrhage per European Cooperative Acute Stroke Study (15.4% versus 3.3%, P=0.0257) and mortality (21.1% versus 5.0%, P=0.0099) and significantly lower independence rate (32.6% versus 53.6%, P=0.0311) were observed among patients > or = 70 years old receiving the standard dose than those receiving the lower dose. This study suggests that the standard dose of 0.9 mg/kg alteplase may not be optimal for treating aged Chinese patients. However, the dose of recombinant tissue plasminogen activator for ischemic stroke in Chinese patients should be based on more broad and convincing evidences and randomized trials of lower versus higher doses are needed.

    The authors assessed efficacy of regional intraosseous administration of urokinase medac in comprehensive treatment of patients with complicated forms of diabetic foot syndrome by means of analysing therapeutic results in a total of 65 patients presenting with pyonecrotic complications of diabetic foot. The patients were subdivided into 2 groups. The control group was composed of 35 patients receiving basic therapy. The study group comprised 30 patients subjected to comprehensive treatment including regional intraosseous (into the heel bone of the affected limb) administration of urokinase medac at a dose of 100 thousand IU for 5 days. Efficacy of treatment was evaluated by the course of the wound process, indices of haemostasis, free radical oxidation, results of surgical treatment. In patients of the Study Group the terms of wound purification from pyonecrotic masses amounted to 9.8±0.3 days, which was by 4.7 days less than in the Control Group patients (p<0.01), marginal epithelialization of wounds also occurred averagely by 6.4 days faster. On day 22 of using the basic therapy alone, the haemostasis system preserved the condition of coagulation activity. The Study Group patients as early as on day 5 of treatment demonstrated shifts towards normocoagulation. In the Control Group by day 22 of treatment, the level of malonic dialdehyde decreased by 18.5%, the index of catalase activity increased by 24.6% (p<0.05); in the Study Group the level of malonic dialdehyde decreased by 42.6% and catalase activity increased by 69.4% (p<0.01). On the background of using urokinase the number of high amputations decreased by 18% and the number of operations with the supporting function preserved decreased by 12% as compared with basic therapy alone. A conclusion was made that additional use of regional intraosseous administration of urokinase medac as compared with basic therapy alone promoted a more significant decrease in the coagulation activity of blood and the level of

    To investigate differences in the effect of intravenous (IV) thrombolysis regarding the mismatch of diffusion-weighted imaging-fluid-attenuated inversion recovery (DWI-FLAIR) among acute ischemic stroke patients who visited the emergency department (ED) within 3 hours from the onset of symptoms. Among ED patients presenting with an acute ischemic stroke between January 2011 and May 2013 at a tertiary hospital, those who underwent magnetic resonance imaging before IV thrombolytic therapy were included in this retrospective study. Patients were divided into DWI-FLAIR mismatch and match groups. National Institutes of Health Stroke Scale (NIHSS) scores obtained initially, 24 hours after thrombolytic therapy, and on discharge, and early neurologic improvement (ENI) and major neurologic improvement (MNI) were compared. During the study period, 50 of the 213 acute ischemic stroke patients who presented to the ED were included. The DWI-FLAIR mismatch group showed a statistically significantly greater reduction in NIHSS both at 24 hours after thrombolytic therapy and upon discharge than did the match group (5.5 vs. 1.2, P<0.001; 6.0 vs. 2.3, P<0.01, respectively). Moreover, ENI and MNI were significantly greater for the DWI-FLAIR mismatch group than for the match group (27/36 vs. 2/14, P<0.001; 12/36 vs. 0/14, P=0.012, respectively). Among acute ischemic stroke patients who visited the ED within 3 hours from the onset of symptoms, patients who showed DWI-FLAIR mismatch showed a significantly better response to IV thrombolytic therapy than did the DWI-FLAIR match group in terms of neurologic outcome.

    A shortage of computed tomographic (CT) machines in low and middle income countries often results in delayed CT imaging for patients suspected of a stroke. Yet, time constraint is one of the most important aspects for patients with an ischemic stroke to benefit from thrombolytic therapy. We set out to assess whether application of the Siriraj Stroke Score is able to assist physicians in prioritizing patients with a high probability of having an ischemic stroke for urgent CT imaging. From the Malaysian National Neurology Registry, we selected patients aged 18 years and over with clinical features suggesting of a stroke, who arrived in the hospital 4.5 hours or less from ictus. The prioritization of receiving CT imaging was left to the discretion of the treating physician. We applied the Siriraj Stroke Score to all patients, refitted the score and defined a cut-off value to best distinguish an ischemic stroke from a hemorrhagic stroke. Of the 2176 patients included, 73% had an ischemic stroke. Only 33% of the ischemic stroke patients had CT imaging within 4.5 hours. The median door-to-scan time for these patients was 4 hours (IQR: 1;16). With the recalibrated score, it would have been possible to prioritize 95% (95% CI: 94%-96%) of patients with an ischemic stroke for urgent CT imaging. In settings where CT imaging capacity is limited, we propose the use of the Siriraj Stroke Score to prioritize patients with a probable ischemic stroke for urgent CT imaging.

    To date, tissue type plasminogen activator (tPA)-based thrombolytic stroke therapy is the only FDA-approved treatment for achieving vascular reperfusion and clinical benefit, but this agent is given to only about 5% of stroke patients in the USA. This may be related, in part, to the elevated risk of symptomatic intracranial hemorrhage, and consequently limited therapeutic time window. Clinical investigations demonstrate that poststroke hyperglycemia is one of the most important risk factors that cause intracerebral hemorrhage and worsen neurological outcomes. There is a knowledge gap in understanding the underlying molecular mechanisms, and lack of effective therapeutics targeting the severe complication. This short review summarizes clinical observations and experimental investigations in preclinical stroke models of the field. The data strongly suggest that interactions of multiple pathogenic factors including hyperglycemia-mediated vascular oxidative stress and inflammation, ischemic insult, and tPA neurovascular toxicity in concert contribute to the BBB damage-intracerebral hemorrhagic transformation process. Development of combination approaches targeting the multiple pathological cascades may help to attenuate the hemorrhagic complication.

    Objectives. Assess the impact of associating thrombolytics, anticoagulants, antiplatelets, and primary angioplasty (PA) on death, reinfarction (AMI), and major bleeding (MB) in STEMI therapy. Methods. Medline search was performed to identify randomized trials comparing these classes in STEMI treatment, at least 500 patients, providing death, AMI, and MB rates. Similar arms were grouped. Correlation between number of drugs and PA and the outcomes was evaluated, as well as correlation between the year of the study and the outcomes. Results. Fifty-nine papers remained after exclusions. 404.556 patients were divided into 35 groups of arms. There was correlation between the number of drugs and rates of death (r = -0.466, P = 0.005) and MB (r = 0.403, P = 0.016), confirmed by multivariate regression. This model also showed that PA is associated with lower mortality and increased MB. Year and period of publication correlated with the outcomes: death (r = -0.380, P < 0.001), MB (r = 0.212, P = 0.014), and AMI (r = -0.231, P = 0.009). Conclusion. The increasing complexity of STEMI treatment has resulted in significant reduction in mortality along with increased rates of MB. Overall, however, the benefits of treatment outweigh the associated risks of MB.

    Creatinine kinase isoenzyme-MB (CK-MB) is a biomarker for detecting myocardial injury. The aim of this study was to evaluate the association between admission CK-MB levels and in-hospital and long-term clinical outcomes in pulmonary embolism (PE) patients treated with thrombolytic tissue-plasminogen activator. A total of 148 acute PE patients treated with tissue-plasminogen activator enrolled in the study. The study population was divided into 2 tertiles, based on admission CK-MB levels. The high CK-MB group (n=35) was defined as having a CK-MB level in the third tertile (>31.5 U/L), and the low group (n=113) was defined as having a level in the lower 2 tertiles (≤31.5 U/L). High CK-MB group had a higher incidence of in-hospital mortality (37.1% vs 1.7%, P<.001). Admission systolic blood pressure and tricuspid annular plane systolic excursion were lower in the high CK-MB group. In the receiver-operating characteristic curve analysis, a CK-MB value of more than 31.5 U/L yielded a sensitivity of 86.7% and specificity of 83.5% for predicting in-hospital mortality. During long-term follow-up, recurrent PE, major and minor bleeding, and mortality rates were similar in both groups. Creatinine kinase isoenzyme-MB is a simple, widely available, and useful biomarker for predicting adverse in-hospital clinical outcomes in PE. Copyright © 2015 Elsevier Inc. All rights reserved.

    To study whether thrombolytic therapy affects Gd-DTPA-enhanced pattern and whether its pattern indicates myocardial viability, Gd-DTPA-enhanced magnetic resonance imaging (MRI) was performed in 43 patients with reperfused acute myocardial infarction 14.8+/-5.0 days after onset with breathhold scanning on a 1.5-T whole body system. The hypoenhanced area at 90 sec after contrast injection was defined as a perfusion defect (PD). Patients were divided into PD(+) and PD(-) groups. The PD was detected in 77.8% of patients treated with direct percutaneous transluminal coronary angioplasty (PTCA) and in 28.6% of patients treated by thrombolytic therapy with or without PTCA in the thrombolysis in myocardial infarction grade 3 group (p < 0.05). The myocardial wall was divided into seven segments based on the American Heart Association committee report. Wall motion of each segment was classified by one of six patterns (wall motion score [WMS]: dyskinesis, -1; akinesis, 0; severe hypokinesis, 1; hypokinesis, 2; slight hypokinesis, 3; normal, 4). By echocardiography, the average WMS and ejection fraction were similar between the PD(+) group and the PD(-) group on admission. Those parameters were significantly worse in the PD(+) group than in PD(-) group 1 month after onset. The change in WMS was significantly lower in the PD(+) group than in the PD(-) group. The number of patients and segments with more than two grades of improvement of WMS in the PD(+) group was significantly lower than that in the PD(-) group. Angiographically, left ventricular ejection fraction and WMS of the PD(+) group were significantly lower than those of the PD(-) group 3 months later. PDs were detected significantly less frequently in patients treated with thrombolytic therapy, suggesting that microvascular embolization related to formation of the no-reflow phenomenon.

    This article concerning the pharmacokinetics and pharmacodynamics of vitamin K antagonists (VKAs) is part of the Seventh American College of Chest Physicians Conference on Antithrombotic and Thrombolytic Therapy: Evidence-Based Guidelines. The article describes the antithrombotic effect of VKAs, the monitoring of anticoagulation intensity, the clinical applications of VKA therapy, and the optimal therapeutic range of VKAs, and provides specific management recommendations. Grade 1 recommendations are strong, and indicate that the benefits do, or do not, outweigh the risks, burdens, and costs. Grade 2 suggests that individual patient's values may lead to different choices (for a full understanding of the grading see Guyatt et al, CHEST 2004; 126:179S-187S). Among the key recommendations in this article are the following: for dosing of VKAs, we suggest the initiation of oral anticoagulation therapy with doses between 5 and 10 mg for the first 1 or 2 days for most individuals, with subsequent dosing based on the international normalized ratio (INR) response (Grade 2B). In the elderly and in other patient subgroups with an elevated bleeding risk, we suggest a starting dose at < or = 5 mg (Grade 2C). We recommend basing subsequent doses after the initial two or three doses on the results of INR monitoring (Grade 1C). The article also includes several specific recommendations for the management of patients with INRs above the therapeutic range and for patients requiring invasive procedures. For example, in patients with mild to moderately elevated INRs without major bleeding, we suggest that when vitamin K is to be given it be administered orally rather than subcutaneously (Grade 1A). For the management of patients with a low risk of thromboembolism, we suggest stopping warfarin therapy approximately 4 days before they undergo surgery (Grade 2C). For patients with a high risk of thromboembolism, we suggest stopping warfarin therapy approximately 4 days before surgery, to

    In 19 patients undergoing intracoronary fibrinolytic therapy for acute myocardial infarction, the site of coronary obstruction was in the proximal right coronary artery. Time between onset of symptoms and hospitalization was less than 4 hours. These patients were studied prospectively by radionuclide techniques immediately after admission, 48 hours and 4 weeks after AMI. Right and left ventricular (RV and LV) ejection fractions (EF) were calculated from gated blood pool scintigrams and the size of the LV perfusion defect was assessed by thallium-201 scintigraphy. Before the intervention, RV performance was significantly lower (RVEF 29 +/- 8%) than normal (53 +/- 7%). The size of the LV perfusion defect was relatively small (less than 25% of LV circumference), and as a consequence, LV pump function was only marginally impaired (LVEF 54 +/- 11%). Recanalization of the infarct artery was achieved in 12 patients (group A); in 7 patients the infarct artery remained occluded (group B). Early after the intervention (48 hours), RV performance in group A recovered significantly (RVEF: 30 +/- 9% vs 39 +/- 7%, p less than 0.01), and further improvement was noted at 4 weeks (RVEF 43 +/- 5%, p less than 0.01).

    Thallium-201 imaging has been utilized to estimate myocardial salvage after thrombolytic therapy for acute myocardial infarction. However, results from recent animal studies have suggested that as a result of reactive hyperemia and delayed necrosis, thallium-201 imaging may overestimate myocardial salvage. To determine whether early overestimation of salvage occurs in humans, intracoronary thallium-201 scans 1 hour after thrombolytic therapy were compared with intravenous thallium-201 scans obtained approximately 10 and 100 days after myocardial infarction in 29 patients. In 10 patients with angiographic evidence of coronary reperfusion, immediate improvement in thallium defects and no interim clinical events, there was no change in imaging in the follow-up studies. Of nine patients with coronary reperfusion but no initial improvement of perfusion defects, none showed worsening of defects in the follow-up images. Six of these patients demonstrated subsequent improvement at either 10 or 100 days after infarction. Seven of 10 patients with neither early evidence of reperfusion nor improvement in perfusion defects had improvement of infarct-related perfusion defects, and none showed worsening. In conclusion, serial scanning at 10 and 100 days after infarction in patients with no subsequent clinical events showed no worsening of the perfusion image compared with images obtained in acute studies. Therefore, there is no evidence that thallium-201 imaging performed early in patients with acute myocardial infarction overestimates improvement.

  16. Targeting therapeutics across the blood brain barrier (BBB), prerequisite towards thrombolytic therapy for cerebrovascular disorders-an overview and advancements.

    Cerebral tissues possess highly selective and dynamic protection known as blood brain barrier (BBB) that regulates brain homeostasis and provides protection against invading pathogens and various chemicals including drug molecules. Such natural protection strictly monitors entry of drug molecules often required for the management of several diseases and disorders including cerebral vascular and neurological disorders. However, in recent times, the ischemic cerebrovascular disease and clinical manifestation of acute arterial thrombosis are the most common causes of mortality and morbidity worldwide. The management of cerebral Ischemia requires immediate infusion of external thrombolytic into systemic circulation and must cross the blood brain barrier. The major challenge with available thrombolytic is their poor affinity towards the blood brain barrier and cerebral tissue subsequently. In the clinical practice, a high dose of thrombolytic often prescribed to deliver drugs across the blood brain barrier which results in drug dependent toxicity leading to damage of neuronal tissues. In recent times, more emphasis was given to utilize blood brain barrier transport mechanism to deliver drugs in neuronal tissue. The blood brain barrier expresses a series of receptor on membrane became an ideal target for selective drug delivery. In this review, the author has given more emphasis molecular biology of receptor on blood brain barrier and their potential as a carrier for drug molecules to cerebral tissues. Further, the use of nanoscale design and real-time monitoring for developed therapeutic to encounter drug dependent toxicity has been reviewed in this study.

  17. Thrombolytic agents in development.

    The quest continues for thrombolytic agents with a higher thrombolytic potency, specific thrombolytic activity and/or a better fibrin selectivity. Several lines of research towards improvement of thrombolytic agents are being explored, including the construction of mutants and variants of plasminogen activators (PAs), chimaeric PAs, conjugates of PAs with monoclonal antibodies, and PAs from animal or bacterial origin. Some of these new thrombolytic agents have shown promise in animal models of venous or arterial thrombosis and in pilot clinical studies. Such molecules include numerous mutants of tissue-type PA (t-PA) with prolonged in vivo half-life and/or resistance to protease inhibitors, and chimaeric PAs consisting of different regions of t-PA and of urokinase-type PA (u-PA). Several molecular forms of the thrombolytic substance in the saliva of the vampire bat have been characterised and cloned. Vampire bat PA exhibits 85% homology to human t-PA but lacks kringle 2 and the plasmin-sensitive cleavage site. A thrombolytic enzyme of 203 amino acids is present in the venom of a southern copperhead snake. This polypeptide, termed fibrolase, is now produced by recombinant technology. Fibrolase does not activate plasminogen or protein C, but directly degrades the alpha and beta chains of fibrin and fibrinogen. Recombinant staphylokinase is not an enzyme, but it forms a 1:1 stoichiometric complex with plasminogen, which becomes active after conversion of plasminogen to plasmin. It is a potent and highly fibrin specific thrombolytic agent in animals and patients.

  18. Delayed adjuvant therapy with the 21-aminosteroid U74006F and the anion channel blocker L644-711 does not improve outcome following thrombolytic therapy in a rabbit model of thromboembolic stroke.

    Both the 21-aminosteroid U74006F, a potent inhibitor of lipid peroxidation, and L644-711, an anion channel blocker that inhibits both neutrophil and astrocyte function, have been previously shown to reduce brain injury in pretreatment paradigms of cerebral ischemia. It was therefore of interest to examine the effect of these agents in combination, when given on a delayed basis as adjuvants to thrombolytic therapy in a rabbit model of thromboembolic stroke. Animals were mechanically ventilated and arterial blood gases controlled. Core and brain temperature, intracranial pressure, and mean arterial pressure were continuously monitored. Regional cerebral blood flow and hematocrit were measured hourly. Blood samples were taken to measure neutrophil (aggregation and chemiluminescence) and platelet (aggregation) activity. Following delivery of an autologous clot via the carotid artery, all experiments were continued for an 8-hour period. U74006F (3 mg/kg I.V.) and L644,711 (12 mg/kg I.V.) or their vehicle control (n = 8, each group) were given 3.5 hours following autologous clot embolization. Both groups received tissue-type plasminogen activator (t-PA) (6.3 mg/kg I.V.), beginning 4 hours following thromboembolic stroke and continuing over a 2-hour infusion period. Infarct size was determined following staining and image analysis. In the L644,711/U74006F group, neutrophil chemiluminescence was reduced following drug therapy; however, there were no significant differences between groups regarding infarct size (50.3 +/- 8.7 vs. 49.9 +/- 10.6, treatment vs. t-PA control, mean +/- SEM), or in regional cerebral blood flow or intracranial pressure over time. It is concluded that prolonged (3.5 hours) delay of the initiation of therapy with the anion channel blocker L644,711 and the 21-aminosteroid U74006F fails to further reduce brain injury when given in combination with tissue plasminogen activator in a rabbit model of thromboembolic stroke.

    The efficacy of thrombolytic therapy for acute ischemic stroke remains controversial in emergency medicine and has not been fully endorsed by either the American College of Emergency Physicians or the American Academy of emergency medicine. A growing recognition exists of the influence of pharmaceutical sponsorship on the reported findings of published clinical trials. Sponsorship bias has been suggested as a potential criticism of the literature and guidelines favoring thrombolytic therapy. The objective of this study is to review the most influential literature regarding thrombolytic therapy for acute ischemic stroke and document the presence or absence of pharmaceutical sponsorship. A publication-citation analysis was performed to identify the most frequently cited articles pertaining to thrombolytic therapy for acute ischemic stroke. Identified articles were reviewed for disclosures of pharmaceutical funding. Of the 20 most-cited articles pertaining to thrombolytic therapy for acute stroke, 17 (85%) disclosed pharmaceutical sponsorship. These disclosures range from general sponsorship to direct employment of authors by pharmaceutical companies. An overwhelming predominance of the most influential literature regarding thrombolytic therapy for acute ischemic stroke is susceptible to sponsorship bias. This potential bias may provide a basis for physician concern regarding the efficacy and safety of thrombolytic therapy. Further, large, independent, placebo-controlled studies may be required to guide therapy and professional guidelines definitively for acute ischemic stroke.

    2012-01-01

    Objective: Our aim was to describe the clinical features of infective endocarditis (IE) in the acute stroke setting and outcomes following thrombolytic therapy. Methods: This is a single-center, retrospective, descriptive case series of IE-related stroke (IES). Infective endocarditis diagnosis was based on the modified Duke criteria. Results: From 2001 to 2007, 18 patients with acute stroke had definite or possible IE. Presenting stroke subtypes were: 11 ischemic stroke; 2 intracerebral hemorrhage; and 5 with a combination of ischemia and subarachnoid hemorrhage. On presentation, 6 had objective fever and 5 had subjective fever, 8 had heart murmur, and 3 had classic IE stigmata. The most common laboratory abnormalities were leukocytosis (n = 11) and anemia (n = 10). Sixteen patients had valvular vegetations on echocardiogram; 6 of 8 patients had vegetations visualized on transesophageal echocardiogram that were not detected by transthoracic echocardiogram. Two of the 3 patients with valve replacements had vegetations only on their native valves. Of 11 patients with pure ischemic stroke, 4 received thrombolytics and had hemorrhagic conversion. Overall mortality of IES was 56% (10 of 18). Mortality in pure ischemic IES patients was 29% (2 of 7, median National Institute of Health Stroke Scale [NIHSS] 13) in those not receiving thrombolytics and 75% (3 of 4, median NIHSS 14) in those receiving thrombolytics. Conclusions: Though diagnosis of IE in the acute stroke setting is difficult, features of the history, examination, and laboratory data may raise concern for IE. In this case series, thrombolytics in patients with IE-associated stroke were associated with very poor outcomes. PMID:23983869

    The evolution of inflammatory diseases has radically changed since the introduction of biologic therapies, such as tumour necrosis factor alpha inhibitors (anti-TNFα). They, therefore, represent a widely used therapeutic modality. Nevertheless, post-marketing studies reveal an increased risk of infection in patients taking these drugs, especially granulomatous infections such as listeriosis. We aimed to evaluate the reported cases of listeriosis in patients treated with biologic treatments. We used the United States Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) from 2004 to 2011. We also perform a literature review of previously reported cases of listeriosis in patients taking biologic therapies. We identified 266 cases of Listeria monocytogenes infection associated with biologic therapies. The majority of patients were receiving infliximab (77.1 %), followed by etanercept (11.7 %), adalimumab (9.8 %), rituximab (4.1 %), abatacept (0.4 %) and golimumab (0.4 %). Indications for the use of biologics were as follows: 47.7 % for rheumatologic diseases, 38 % for inflammatory bowel diseases, 3.4 % for haematological diseases and 10.5 % for other indications. Seventy-three percent of the patients were receiving concomitant immunosuppressant drugs, especially steroids (56 %) and methotrexate (31.6 %). The median time to the onset of infection was 184 days. Mortality rates range from 11.1 % in adalimumab-treated patients to 27.3 % in rituximab-treated patients (p = 0.7). Listeriosis is common in biologics-treated patients, especially related to infliximab use given concomitantly with other immunosuppressive therapies. Infections after treatment with biologics mostly occurred in the first year after initiating treatment.

    Objective To investigate the effects of the combination of extracorporeal cardiopulmonary resuscitation (ECPR) and thrombolytic therapy on the recovery of vital organ function after prolonged cardiac arrest. Design Laboratory investigation Setting University Laboratory Subjects Pigs Interventions Animals underwent 30-minute untreated ventricular fibrillation cardiac arrest followed by extracorporeal cardiopulmonary resuscitation (ECPR) for 6 hours. Animals were allocated into two experimental groups: t-ECPR, which received Streptokinase 1 MU and c-ECPR which did not receive Streptokinase. In both groups the resuscitation protocol included the following physiologic targets: mean arterial pressure (MAP) > 70 mmHg, Cerebral perfusion pressure (CerPP) > 50 mmHg, PaO2 150 ± 50 mmHg, PaCO2 40 ± 5 mmHg and core temperature 33 ± 1 °C. Defibrillation was attempted after 30 minutes of ECPR. Measurements and Main Results A cardiac resuscitability score was assessed on the basis of: success of defibrillation; return of spontaneous heart beat; weanability form ECPR; and left ventricular systolic function after weaning. The addition of thrombolytic to ECPR significantly improved cardiac resuscitability (3.7 ± 1.6 in t-ECPR vs 1.0 ± 1.5 in c-ECPR). Arterial lactate clearance was higher in t-ECPR than in c-ECPR (40 ± 15% VS 18 ± 21 %). At the end of the experiment, the intracranial pressure was significantly higher in c-ECPR than in t-ECPR. Recovery of brain electrical activity, as assessed by quantitative analysis of EEG signal, and ischemic neuronal injury on histopathologic examination did not differ between groups. Animals in t-ECPR group did not have increased bleeding complications, including intracerebral hemorrhages. Conclusions In a porcine model of prolonged cardiac arrest, thrombolytic-enhanced ECPR improved cardiac resuscitability and reduced brain edema, without increasing bleeding complications. However, early EEG recovery and ischemic neuronal injury were

    Citation bias occurs when positive trials involving a medical intervention receive more citations than neutral or negative trials of similar quality. Several large clinical trials have studied the use of thrombolytic agents for the treatment of acute ischemic stroke with differing results, thereby presenting an opportunity to assess these trials for evidence of citation bias. We compared citation rates among positive, neutral, and negative trials of alteplase (tPA) and other thrombolytic agents for stroke. We used a 2014 Cochrane Review of thrombolytic therapy for the treatment of acute stroke to identify non-pilot, English-language stroke trials published in MEDLINE-indexed journals comparing thrombolytic therapy with control. We classified trials as positive if there was a statistically significant primary outcome difference favoring the intervention, neutral if there was no difference in primary outcome, or negative for a significant primary outcome difference favoring the control group. Trials were also considered negative if safety concerns supported stopping the trial early. Using Scopus, we collected citation counts through 2015 and compared citation rates according to trial outcomes. Eight tPA trials met inclusion criteria: two were positive, four were neutral, and two were negative. The two positive trials received 9080 total citations, the four neutral trials received 4847 citations, and the two negative trials received 1096 citations. The mean annual per-trial citation rates were 333 citations per year for positive trials, 96 citations per year for neutral trials, and 35 citations per year for negative trials. Trials involving other thrombolytic agents were not cited as often, though as with tPA, positive trials were cited more frequently than neutral or negative trials. Positive trials of tPA for ischemic stroke are cited approximately three times as often as neutral trials, and nearly 10 times as often as negative trials, indicating the presence of

    Abstract: Tissue plasminogen activator (t-PA) is the only FDA-approved drug for acute ischemic stroke treatment, but its clinical use is limited due to the narrow therapeutic time window and severe adverse effects, including hemorrhagic transformation (HT) and neurotoxicity. One of the potential resolutions is to use adjunct therapies to reduce the side effects and extend t-PA's therapeutic time window. However, therapies modulating single target seem not to be satisfied, and a multi-target strategy is warranted to resolve such complex disease. Recently, large amount of efforts have been made to explore the active compounds from herbal supplements to treat ischemic stroke. Some natural compounds revealed both neuro- and blood-brain-barrier (BBB)-protective effects by concurrently targeting multiple cellular signaling pathways in cerebral ischemia-reperfusion injury. Thus, those compounds are potential to be one-drug-multi-target agents as combined therapy with t-PA for ischemic stroke. In this review article, we summarize current progress about molecular targets involving in t-PA-mediated HT and neurotoxicity in ischemic brain injury. Based on these targets, we select 23 promising compounds from currently available literature with the bioactivities simultaneously targeting several important molecular targets. We propose that those compounds merit further investigation as combined therapy with t-PA. Finally, we discuss the potential drawbacks of the natural compounds' studies and raise several important issues to be addressed in the future for the development of natural compound as an adjunct therapy.

    Previous reports indicate that patients who do not develop Q waves after thrombolytic therapy are a different population with a better long-term survival than those who do develop Q waves. However, the use of resources, quality of life, and health status of this population have not been fully evaluated. Using data from the Economics and Quality of Life subset of the Global Utilization of Streptokinase and tPA for Occluded Arteries study, we examined 30-day and 1-year mortality, use of resources, and quality-of-life measures among 1,830 of 3,000 patients with acute myocardial infarction and ST-segment elevation treated with thrombolytic therapy. At hospital discharge, 555 patients (30.2%) had not developed Q waves. These patients had lower mortality than patients with Q waves at 30 days (1.6% vs 4.5%, p <0.01) and at 1 year (4.7% vs 6.8%, p <0.04). Recurrent chest pain and dyspnea were similar at 30 days and 1 year. Patients without Q waves had significantly more angiography and trends toward higher readmission, revascularization, and use of calcium antagonists at 30 days. Angiography, revascularization, readmission, and quality of life were equivalent from 30 days to 1 year, with no sign of late instability. Logistic regression analysis showed an association between in-hospital revascularization and better survival and quality of life at 1 year. Conversely, there was no association between in-hospital use of calcium antagonists and outcome to explain the lower mortality in non-Q-wave patients. The absence of Q waves after thrombolytic therapy is a marker of success, implying better prognosis and equivalent quality of life, use of resources, and health status than for patients with Q-wave acute myocardial infarction and no sign of long-term unstable clinical course.

    The high prevalence of dysphagia after stroke leads to increased mortality, and cerebral reperfusion therapy has been effective in reducing neurologic deficits. The aim of this study was to investigate the severity and evolution of dysphagia and the occurrence of pneumonia in patients submitted to cerebral reperfusion therapy. Seventy ischemic stroke patients were evaluated. Of these, 35 patients (group 1) were submitted to cerebral reperfusion therapy and 35 (group 2) did not receive thrombolytic treatment. The following were evaluated: severity of dysphagia by means of videofluoroscopy, evolution of oral intake rate by means of the Functional Oral Intake Scale, and the occurrence of pneumonia by international protocol. The relation between the severity of dysphagia and the occurrence of pneumonia with the treatment was evaluated through the chi-square test; the daily oral intake rate and its relation to the treatment were assessed by the Mann-Whitney test and considered significant if P is less than .05. The moderate and severe degrees of dysphagia were more frequent (P=.013) among the patients who were not submitted to cerebral reperfusion therapy. The daily oral intake evolved independently of the treatment type, without statistical significance when compared between the groups, whereas pneumonia occurred more frequently in group 2 (28%) in relation to group 1 (11%) and was associated with the worst degrees of dysphagia (P=.045). We can conclude that there is improvement in the oral intake rate in both groups, with lower severity of dysphagia and occurrence of pneumonia in ischemic stroke patients submitted to cerebral reperfusion therapy.

    Purpose. To carry out a retrospective analysis of patients with acute dural sinus thrombosis, and the role of cerebral venous congestion in patient management. Methods. Twenty-five patients were identified with the clinical and imaging diagnosis of acute dural sinus thrombosis. The imaging diagnosis was by magnetic resonance (MR) and/or computed tomography (CT) venography. There was a female predominance with a female to male ratio of 1.5 to 1 (16 women, 9 men). The age range was from 19 to 64 years old with an average age of 37 years. The first 10 patients, who ranged in age from 21 to 64 years old (average 37 years), received only anticoagulation therapy with heparin and warfarin for periods ranging from 5 days to 2 months. The remaining 15 patients ranged in age from 19 to 57 years old (average 38 years). They either underwent subsequent thrombectomy after a trial of anticoagulation therapy, or went straight to thrombectomy. These latter 15 patients had initial evidence of cerebral venous congestion, either clinically by severe or worsening symptoms despite anticoagulation therapy, or on initial or subsequent CT or MR imaging. In our experience, the cerebral venous congestion imaging findings included intracranial hemorrhage, a hematoma, or edema. The thrombolytic treatment technique consisted of the advancement of a 6 Fr guiding catheter to the jugular bulb or sigmoid sinus from a transfemoral approach. A microcatheter was then advanced to the proximal portion of the thrombus and then either tissue plasminogen activator (tPA) or urokinase was injected to prevent clot propagation. A balloon catheter was used to perform thrombectomy since the thrombolytic agents can be injected via the inner lumen with an inflated balloon. The inflated balloon helped to keep the venous flow from washing out the thrombolytic agent, thus facilitating the agent's effect. Results. The first 10 patients received only anticoagulation therapy with heparin and warfarin for periods

    Inhibiting estrogen production is a common means of preventing breast cancer recurrence. The aromatase inhibitors (AIs) are becoming the preferred treatment over tamoxifen as adjuvant therapy for postmenopausal women with hormone-sensitive early breast cancer. Like all adjuvant therapies, AIs have adverse events (AEs) associated with their use, many of which resemble symptoms common to menopause. Because of the greater efficacy of AIs in preventing breast cancer recurrence over tamoxifen, these AEs may be considered tolerable by many patients and often can be effectively managed and/or prevented. Educating patients about anticipated AEs may help them understand, accept, and cope with these AEs. This article reviews the AEs associated with different adjuvant AI treatments and highlights some strategies to manage them effectively. It also highlights the importance of patient education regarding AI therapy and involvement in treatment decisions, which may lead to better long-term adherence and ultimately to better outcomes.

    The aim of this study was to evaluate the effects of music therapy on anxiety, postoperative pain and physiological reactions to emotional and physical distress in patients undergoing spinal surgery. Surgery-related anxiety and pain are the greatest concern of surgical patients, especially for those undergoing major procedures. A quasi-experimental study design was conducted in a medical centre in Taiwan from April-July 2006. Sixty patients were recruited. The study group listened to selected music from the evening before surgery to the second day after surgery. The control group did not listen to music. Patients' levels of anxiety and pain were measured with visual analogue scales (VAS). Physiological measures, including heart rate, blood pressure and 24-hour urinalysis, were performed. The average age of the 60 patients was 62·18 (SD 18·76) years. The mean VAS score for degree of anxiety in the study group was 0·8-2·0, compared with 2·1-5·1 in the control group. The mean VAS score for degree of pain in the study group was 1·7-3·0, compared with 4·4-6·0 in the control group. The differences between the two groups in VAS scores for both anxiety (p = 0·018-0·001) and pain (p = 0·001) were statistically significant. One hour after surgery, the mean blood pressure was significantly lower in the study group than in the control group (p = 0·014), but no significant differences were found between the two groups in urine cortisol (p = 0·145-0·495), norepinephrine (p = 0·228-0·626) or epinephrine values (p = 0·074-0·619). Music therapy has some positive effects on levels of anxiety and pain in patients undergoing spinal surgery. Complementary music therapy can alleviate pain and anxiety in patients before and after spinal surgery. © 2011 Blackwell Publishing Ltd.

    To provide a national assessment of thrombolytic administration using drip-and-ship treatment paradigm. Patients treated with the drip-and-ship paradigm among all acute ischemic stroke patients treated with thrombolytic treatment were identified within the Nationwide Inpatient Sample. Thrombolytic utilization, patterns of referral, comparative in-hospital outcomes, and hospitalization charges related to drip-and-ship paradigm were determined. All the in-hospital outcomes were analyzed after adjusting for potential confounders using multivariate analysis. Of the 22 243 ischemic stroke patients who received thrombolytic treatment, 4474 patients (17%) were treated using drip-and-ship paradigm. Of these 4474 patients, 81% were referred to urban teaching hospitals for additional care, and 7% of them received follow-up endovascular treatment. States with a higher proportion of patients treated using the drip-and-ship paradigm had higher rates of overall thrombolytic utilization (5.4% versus 3.3%; P<0.001). The rate of home discharge/self-care was significantly higher in patients treated with drip-and-ship paradigm compared with those who received thrombolytics through primary emergency department arrival in the multivariate analysis (OR, 1.198; 95% CI, 1.019-1.409; P=0.0286). One of every 6 thrombolytic-treated patients in United States is treated using drip-and-ship paradigm. States with the highest proportion of drip-and-ship cases were also the states with the highest thrombolytic utilization.

    Vasopressor infusion (VPI) is used to treat hypotension in an ICU. We studied compliance with blood pressure (BP) goals during VPI and whether a statistical model might be efficacious for advance warning of impending hypotension, compared with a basic hypotension threshold alert. Retrospective data were obtained from a public database. Studying adult ICU patients receiving VPI at submaximal dosages, we analyzed characteristics of sustained hypotension episodes (>15 min) and then developed a logistic regression model to predict hypotension episodes using input features related to BP trends. The model was then validated with prospective data. In the retrospective dataset, 102-of-215 ICU stays experienced >1 hypotension episode (median of 2.5 episodes per day in this subgroup). When trained with 75% of retrospective dataset, testing with the remaining 25% of the dataset showed that the model and the threshold alert detected 99.6% and 100% of the episodes, respectively, with median advance forecast times (AFT) of 12 and 0 min. In a second, prospective dataset, the model detected 100% of 26 episodes with a median AFT of 22 min. In conclusion, episodes of hypotension were common during VPI in the ICU. A logistic regression model using BP temporal trend features predicted the episodes before their onset.

    There are a few stroke specialists in medically under-served areas in Japan. Consequently, in remote area patients may not receive thrombolysis with intravenous recombinant tissue plasminogen activator (iv rt-PA), the standard treatment for acute ischemic stroke. Using a mobile telestroke support system (TSS) that accesses the internet via a smart phone, we implemented iv rt-PA infusion therapy under a drip-and-ship protocol to treat the stroke patients in medically under-served areas. The physicians at the Tokushima Prefectural Kaifu Hospital (TPKH), located in rural Japan, can relay CT or MRI scans and other patient data via their smart phone to off-site stroke specialists. In the course of 34 months, we used the TSS in 321 emergencies. A total of 9 of 188 (4.8%) with acute ischemic stroke, received iv rt-PA infusion therapy using a mobile TSS; in 5 among these (55.6%), we obtained partial or complete recanalization of occluded arteries. None suffered post-treatment hemorrhage and their average NIH stroke score fell from 14.6 at the time of admission to 6.8 at 24 h post-infusion. The drip-and-ship protocol contributed to the safe and effective treatment of the stroke patients living in medically under-served rural areas. PMID:27333939

    Data on the utilization of occupational therapy among patients with brain tumors have been limited to those with malignant tumors and small samples of patients outside North America in specialized palliative care settings. We built on this research by examining the characteristics of patients with brain tumors who received postacute occupational therapy services in Ontario, Canada, using health care administrative data. Between fiscal years 2004-2005 and 2008-2009, 3,199 patients with brain tumors received occupational therapy services in the home care setting after hospital discharge; 12.4% had benign brain tumors, 78.2% had malignant brain tumors, and 9.4% had unspecified brain tumors. However, patients with benign brain tumors were older (mean age=63.3 yr), and a higher percentage were female (65.2%). More than 90% of patients received in-home occupational therapy services. Additional research is needed to examine the significance of these differences and to identify factors that influence access to occupational therapy services in the home care setting.

    To date, no ischemic stroke outcome prediction scores have been validated for use in the setting of both endovascular and non-endovascular stroke treatments. The Totaled Health Risks in Vascular Events (THRIVE) score has been previously validated in patients undergoing endovascular stroke treatment, and we hypothesized that it would perform similarly well in patients receiving intravenous tissue plasminogen activator (tPA) or no acute therapy. We compared the performance of the THRIVE score between patients in the National Institutes of Neurological Disorders and Stroke (NINDS) tPA trial and patients in the Mechanical Embolus Removal in Cerebral Ischemia (MERCI) trials of endovascular stroke treatment. The predictive performance of the THRIVE score was compared using receiver operator characteristic (ROC) curve analysis. In the NINDS cohort, separate analyses were also performed for patients receiving tPA versus those receiving placebo. ROC curve analysis revealed a good prediction of outcomes across the range of THRIVE scores in both the NINDS and MERCI datasets. As we have previously found in the MERCI datasets, the THRIVE score, which encompasses the National Institutes of Health Stroke Scale (NIHSS) score, age, and chronic disease burden, was a better predictor of outcomes than NIHSS and age alone in the NINDS trial dataset. THRIVE score and tPA administration both strongly predicted outcome, but these effects were statistically independent. The THRIVE score provides accurate prediction of long-term neurologic outcomes in patients with acute ischemic stroke regardless of treatment modality. Both the THRIVE score and tPA administration predict outcome, but the THRIVE score does not influence the impact of tPA on outcome, and tPA administration does not influence the impact of THRIVE score on outcome.

  1. Third-generation thrombolytic drugs.

    PubMed

    Verstraete, M

    2000-07-01

    Several third-generation thrombolytic agents have been developed. They are either conjugates of plasminogen activators with monoclonal antibodies against fibrin, platelets, or thrombomodulin; mutants, variants, and hybrids of alteplase and prourokinase (amediplase); or new molecules of animal (vampire bat) or bacterial (Staphylococcus aureus) origin. These variations may lengthen the drug's half-life, increase resistance to plasma protease inhibitors, or cause more selective binding to fibrin. Compared with the second-generation agent (alteplase), third-generation thrombolytic agents such as monteplase, tenecteplase, reteplase, lanoteplase, pamiteplase, and staphylokinase result in a greater angiographic patency rate in patients with acute myocardial infarction, although, thus far, mortality rates have been similar for those few drugs that have been studied in large-scale trials. Bleeding risk, however, may be greater.

    An MRI compatible PVDF receiver was designed and manufactured for integration into a transcranial therapy array. 4.8 mm diameter, 110 μm thick PVDF film was air-backed by clamping it across brass tubing. A preamplifier was enclosed within the tubing to improve SNR and drive the long coaxial cables required to reach outside the MRI. The receiver was mounted inside a ring element from an existing array. The receiver performance was compared with a commercial needle hydrophone and tested for MRI compatibility. The PVDF receiver displayed a higher sensitivity than the needle hydrophone and a better capability to reject electrical coupling with the transmit element. MRI image artifacts created by the device were small, and diagnostic ultrasound was possible with the device while simultaneously obtaining an MRI image. Microbubble contrast agent was sonicated both directly, and through a fragment of human skull. The transmit/receive pair was successful in sonicating the microbubbles transcranially and detecting the returning microbubble emissions. A second generation receiver with a diameter of 2.4 mm was manufactured, without sacrificing sensitivity, to increase the field of view of the device. Future work will focus on developing a multi-element receiver array and its testing for brain treatment monitoring.

    Patients with pulmonary thromboembolism (PE) often decompensate suddenly, and once hemodynamic compromise has developed, mortality is extremely high. Currently, thrombolytic therapy for PE is still controversial. We retrospectively evaluated 34 patients with PE between January 2010 and December 2013 in the Department of Pulmonary Medicine, Medical Park Samsun Hospital, Samsun, Turkey. The demographic and disease characteristics of patients who received thrombolytic treatment were retrospectively analyzed. The female to male ratio was 19/15 and the mean age was 63.1±13.2 years. PE diagnosis was made using echocardiography (64.7%) or contrast-enhanced thorax computed tomography with echocardiography (32.4%). Twenty-two (64.7%) patients went into the cardiopulmonary arrest due to massive PE and 17 (50%) patients recovered without sequelae. Eleven (32.4%) patients were diagnosed with massive PE during cardiopulmonary arrest with clinical and echocardiographic findings. Alteplase (recombinant tissue plasminogen activator [rt-PA]) was administered during cardiopulmonary resuscitation (CPR) and four (36.3%) patients responded and survived without sequelae. The complications of rt-PA treatment were hemorrhage in five (14.7%) patients and allergic reactions in two (5.9%) patients. There was no mortality due to rt-PA treatment complications. In conclusion, mortality due to massive PE is much more than estimated and alteplase can be used safely in patients with massive PE. This thrombolytic treatment was not associated with any fatal hemorrhage complication. If there is any sign of acute PE, echocardiography should be used during cardiopulmonary arrest/instability. Alteplase should be given to patients with suspected massive PE.

    We performed a qualitative study to identify facilitators of and barriers to the implementation of national guidelines on thrombolytic therapy for acute ischemic stroke. We interviewed physicians and nurses at nine Swedish hospitals using 16 explorative, semistructured interviews, and selected hospitals based on their implementation rate of new stroke care methods according to data from the Swedish Stroke Register, Riks-Stroke. Through content analysis, we identified facilitators and barriers to implementation, which we classified into three categories: (a) individuals, (b) social interactions and context, and (c) organizational and resource issues. Insights obtained from this study can be used to identify target areas for improving the implementation of thrombolytic therapy and other new methods in stroke care.

    The contingent negative variation, an event-related potential related to neural activity in the frontal lobe and basal ganglia, neuropsychological tests and structural MRI were used to examine CNS function and structure in HIV-positive patients receiving antiretroviral therapy. Relative to controls, HIV patients had smaller thalamic volume and reduced late contingent negative variation amplitude that correlated with caudal atrophy. Behaviorally, viremic patients were more impaired than virally suppressed patients and controls on neuropsychological measures of psychomotor speed, selective attention and mental flexibility. These results suggest that antiretroviral therapy may not be effective in protecting cortical and subcortical structures against HIV-related neuropathology, regardless of immune function. However, the benefits of antiretroviral therapy on immune function appear to facilitate neurocognitive performance. PMID:14600507

    The extent of use of alternative therapies, psychosocial and disease-specific variables predictive of alternative therapy use, and factors motivating the use of alternative therapies in HIV-infected patients receiving highly active antiretroviral therapy (HAART) have not been well defined. Types of alternative therapies used, demographic and medical data, coping (Billing and Moos inventory of coping with illness styles), social support (Irwing and Sarason questionnaire), sense of personal control (Pearlin's Mastery scale), quality of life (Medical Outcome Study scale), health beliefs, and adherence rate were prospectively assessed in 118 HIV-infected patients receiving HAART. Of 38% (45/118) of the patients who used alternative therapies, 56% (25/45) began using alternative therapies since the initiation of HAART. While Caucasian patients were more likely to use alternative therapies than all other patients (P = 0.015), new users of alternative therapies were more likely to be African-American (P = 0.022). Alternative therapy users reported less satisfaction with their emotional support (P = 0.027), and had greater psychological distress (P = 0.048), but were more likely to utilize problem-focused coping (P = 0.015). Patients who used alternative therapies were less likely to believe that HAART was beneficial (P = 0.06). Physicians were unaware of patients' alternative therapy use in 40% (18/45) of all patients who used alternative therapies, in 67% of herbal therapy users, and in 100% of dietary supplement users. Adherence to antiretroviral therapy, CD4 count, and HIV-RNA level were neither predictive nor affected by alternative therapy use. Despite scepticism about the benefits of HAART, resort to alternative therapies did not undermine adherence with antiretroviral therapy. Although able actively to cope with their illness, users of alternative therapies had greater psychological distress and were less satisfied with their emotional support. Interventions aimed

    To investigate the safety of electroconvulsive therapy (ECT) in patients receiving long-term warfarin therapy. Retrospective data were reviewed for 35 consecutively hospitalized patients who received long-term warfarin therapy and ECT at the Mayo Clinic in Rochester, Minn, between January 1, 1994, and December 31, 2001. A total of 300 ECT treatments were administered to the 35 patients. Of 284 ECT treatments for which data were available, no ECT-related complications due to anticoagulation occurred despite increases in blood pressure and pulse rate. One patient experienced ventricular tachycardia, resulting in transfer to a cardiology service for temporary monitoring. No other serious ECT-related adverse effects were noted. The rate of intertreatment delirium was similar to that reported in other studies. Electroconvulsive therapy in patients receiving long-term warfarin therapy appears to be safe. Although no major adverse effects were identified in our case series, additional prospective evaluation is warranted.

    ABSTRACT Cardiovascular disorders are on the rise worldwide due to alcohol abuse, obesity, hypertension, raised blood lipids, diabetes and age-related risks. The use of classical antiplatelet and anticoagulant therapies combined with surgical intervention helped to clear blood clots during the inceptive years. However, the discovery of streptokinase and urokinase ushered the way of using these enzymes as thrombolytic agents to degrade the fibrin network with an issue of systemic hemorrhage. The development of second generation plasminogen activators like anistreplase and tissue plasminogen activator partially controlled this problem. The third generation molecules, majorly t-PA variants, showed desirable properties of improved stability, safety and efficacy with enhanced fibrin specificity. Plasmin variants are produced as direct fibrinolytic agents as a futuristic approach with targeted delivery of these drugs using liposome technlogy. The novel molecules from microbial, plant and animal origin present the future of direct thrombolytics due to their safety and ease of administration. PMID:27696935

    To present a pharmaceutical care program for pediatric patients receiving antiretroviral therapy. In order to establish the pharmaceutical care procedure, papers published up to 2004 on the pharmaceutical care provided to patients receiving antiretroviral therapy were reviewed through a search in Medline and the journal Farmacia Hospitalaria. In addition, bibliographic references that can be systematically used to analyze the pharmacotherapy of each patient have been selected. The pharmaceutical care procedure is divided in three stages (data collection, analysis of the pharmacotherapeutic profile and resolution of the drug-related problems identified) that take place through a semi-structured type of interview. In order to systematize the role of the pharmacist, a table with information on antiretroviral drugs used in Pediatrics was created, as well as an information three-page leaflet and a data collection form. The program includes the goals of the pharmaceutical care process as defined in the recommendations of GESIDA-SEFH-National AIDS Plan 2004 and systematizes the proposed intervention strategies, in an attempt to provide the patient and the caregiver with the information required for an optimum management, in the most comprehensive way and tailored to their individual characteristics.

    Abstract The aim of our investigation was to verify whether phage therapy (PT) can induce antiphage antibodies. The antiphage activity was determined in sera from 122 patients from the Phage Therapy Unit in Wrocław with bacterial infections before and during PT, and in sera from 30 healthy volunteers using a neutralization test. Furthermore, levels of antiphage antibodies were investigated in sera of 19 patients receiving staphylococcal phages and sera of 20 healthy volunteers using enzyme-linked immunosorbent assay. The phages were administered orally, locally, orally/locally, intrarectally, or orally/intrarectally. The rate of phage inactivation (K) estimated the level of phages' neutralization by human sera. Low K rates were found in sera of healthy volunteers (K≤1.73). Low K rates were detected before PT (K≤1.64). High antiphage activity of sera K>18 was observed in 12.3% of examined patients (n=15) treated with phages locally (n=13) or locally/orally (n=2) from 15 to 60 days of PT. High K rates were found in patients treated with some Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus faecalis phages. Low K rates were observed during PT in sera of patients using phages orally (K≤1.04). Increased inactivation of phages by sera of patients receiving PT decreased after therapy. These results suggest that the antiphage activity in patients' sera depends on the route of phage administration and phage type. The induction of antiphage activity of sera during or after PT does not exclude a favorable result of PT. PMID:24893003

    Background Dual anti platelet therapy consists of administering antiplatelet (antiaggregant) drugs (clopidogrel and aspirin) to prevent thrombotic processes, as a preventative measure in patients with acute coronary disease, or in patients subjected to percutaneous coronary intervention. Objectives The purpose of this study was to evaluate the efficacy of a protocol for performing dental extraction in patients receiving dual anti platelet therapy. Material and Methods Thirty-two patients undergoing dental extractions were included in the study. The variables evaluated were: collagen-epinephrine fraction, collagen- adenosine diphosphate fraction, surgical surface, post-surgical measures, and adverse effects. Alveolar sutures and gauzes impregnated with an antifibrinolytic agent (tranexamic acid), which the patient pressed in place for 30 minutes, were applied to all patients as post-surgical measures. Descriptive statistics were calculated and analyzed with Student’s t-test to compare pairs of quantitative variables; simple regression analysis was performed using Pearson’s correlation coefficient. Statistical significance was set at p<0.05. Results Collagen/epinephrine fraction was 264.53±55.624 seconds with a range of 135 to 300 seconds, and collagen/ADP fraction was 119.41±44.216 seconds, both values being higher than normal. As a result of the post-surgical measures taken, no patients presented postoperative bleeding, hematoma or infection. Conclusions Dental extraction was safe for patients receiving dual anti-platelet therapy when using sutures and gauze impregnated with tranexamic acid, which the patient pressed in place for 30 minutes.

    Recent reports of bisphosphonate-related osteonecrosis of the jaw (BRONJ) have increased awareness of oral health in patients receiving osteoporosis therapy. This study describes the demographic, oral health, and clinical characteristics of a contemporary population of women aged 50 and older undergoing oral bisphosphonate treatment who returned a mailed questionnaire pertaining to dental symptoms. The study, as previously reported, was conducted within Kaiser Permanente Northern California, a large, integrated healthcare delivery system. The cohort included 7,909 women with bisphosphonate exposure of at least 1 year, with a subset of 923 women reporting dental symptoms who underwent clinical examination. Overall, the average age was 71 ± 9; 70% were white, and 74% had at least some college education. Nearly two-thirds had received oral bisphosphonate therapy for 3 or more years. Most reported daily tooth brushing, 85% had had a dental examination in the past year, 22% reported denture use, and 6% reported moderate to severe periodontal disease. Oral healthcare patterns varied according to age and race and ethnicity. Five hundred seven (6.4%) women reported a tooth extraction in the prior year, of whom two developed BRONJ (0.4%). Tori or exostoses were found in 28% of examined participants with dental symptoms; these were predominantly in the lingual mandible and palate, with palatal BRONJ occurring in 1.6% of symptomatic participants with palatal tori. In summary, among older women with bisphosphonate exposure, oral health varied according to patient characteristics, and BRONJ occurred more frequently after tooth extraction or on palatal tori. These data support efforts to optimize oral health and to identify risk factors for BRONJ in older individuals receiving bisphosphonate drugs. © 2011, Copyright the Authors.

    Background Testosterone therapy for older men has increased substantially over the past decade. Research on the effects of testosterone therapy on cardiovascular outcomes has yielded inconsistent results. Objective To examine the risk of myocardial infarction (MI) in a population-based cohort of older men receiving intramuscular testosterone. Method Using a 5% national sample of Medicare beneficiaries, we identified 6355 patients treated with at least 1 injection of testosterone between January 1, 1997, and December 31, 2005. We matched this cohort to 19 065 testosterone nonusers at a 1:3 ratio based on a composite MI prognostic score. Patients were followed until December 31, 2005, or until they lost coverage from Medicare, enrolled in a health maintenance organization, experienced a MI, or died. Result In a Cox regression analysis adjusting for demographic and clinical characteristics, receipt of testosterone therapy was not associated with an increased risk of MI (hazard ratio [HR] = 0.84; 95% CI = 0.69–1.02). In this analysis, there was an interaction between receipt of testosterone and quartile of risk of MI (P = 0.023). For men in the highest quartile of the MI prognostic score, testosterone therapy was associated with a reduced risk of MI (HR = 0.69; 95% CI = 0.53–0.92), whereas there was no difference in risk for the first (HR = 1.20; 95% CI = 0.88–1.67), second (HR = 0.94; 95% CI = 0.69–1.30), and third quartiles (HR = 0.78; 95% CI = 0.59–1.01). Conclusion Older men who were treated with intramuscular testosterone did not appear to have an increased risk of MI. For men with high MI risk, testosterone use was modestly protective against MI.

    Approximately 100,000 patients begin hemodialysis each year in the United States. Although an arteriovenous fistula or graft is the preferred method for long-term vascular access during hemodialysis, as these types of vascular access are the most reliable, approximately 30% of patients require the use of catheters to continue hemodialysis. Tunneled, cuffed hemodialysis catheters are discouraged for permanent vascular access because of their high rates of infection, morbidity and mortality, and thrombotic and technical complications. These catheters have a short functional life span and require medical intervention, often thrombolytic therapy, to treat the catheter malfunction. No thrombolytic agent is specifically indicated for the management of occluded hemodialysis catheters. Thus, we performed a systematic review to critically evaluate all available studies that examined the efficacy, safety, and cost of thrombolytic therapy for the management of dysfunctional hemodialysis catheters. Studies were included if they reported efficacy in a specific proportion of affected dysfunctional hemodialysis catheters; reported the proportion of patients experiencing an adverse outcome (especially bleeding); and described the type of catheter used, dose of thrombolytic agent, administration protocol, dwell time, definition of treatment success, time to follow-up for study end points, and sample size. Eighteen studies met the inclusion criteria. The mean ± SD success rate in clearing dysfunctional hemodialysis catheters was greatest with reteplase at 88 ± 4%, followed by alteplase at 81 ± 37% and tenecteplase at 41 ± 5%. Adverse effects associated with the use of these thrombolytic agents administered at low doses were extremely rare. No serious adverse bleeding events attributed to thrombolytic therapy were reported in any of the trials. Aliquotted reteplase from vials for intravenous use was the least costly thrombolytic agent. Thus, at centers that use high volumes of

    When a previously healthy adult experiences atraumatic cardiac arrest, providers must quickly identify the etiology and implement potentially lifesaving interventions such as advanced cardiac life support. A subset of these patients develop cardiac arrest or periarrest due to pulmonary embolism (PE). For these patients, an early, presumptive diagnosis of PE is critical in this patient population because administration of thrombolytic therapy may significantly improve outcomes. This article reviews thrombolysis as a potential treatment option for patients in cardiac arrest or periarrest due to presumed PE, identifies features associated with a high incidence of PE, evaluates thrombolytic agents, and systemically reviews trials evaluating thrombolytics in cardiac arrest or periarrest. Despite potentially improved outcomes with thrombolytic therapy, this intervention is not without risks. Patients exposed to thrombolytics may experience major bleeding events, with the most devastating complication usually being intracranial hemorrhage. To optimize the risk-benefit ratio of thrombolytics for treatment of cardiac arrest due to PE, the clinician must correctly identify patients with a high likelihood of PE and must also select an appropriate thrombolytic agent and dosing protocol.

  17. What you should know about the 2008 American College of Chest Physicians evidence-based clinical practice guidelines (8th) on antithrombotic and thrombolytic therapy.

    The American College of Chest Physicians published their first consensus conference guidelines on antithrombotic therapy in 1986 and has updated these guidelines approximately every 3 years as a supplement to the journal Chest. These guidelines are widely accepted as an authoritative source of information and considered by many to be the textbook for antithrombotic therapy. The most recent guidelines are from the 8th consensus conference, published in 2008, and this article will highlight new recommendations that have evolved since the 2004 Chest supplement. Examples from the literature that support the evolution these guidelines will focus on changes that are most germane to the majority of attendees at the 10th National Conference on Anticoagulant Therapy and members of the AC Forum. The objective of this article is to help answer ten common clinical questions frequently faced by anticoagulation management services.

    Over a 10-year period a uniform management plan for patients receiving long term oral anticoagulation therapy for prosthetic heart valves and needing dental procedures was instituted. Those undergoing dental extraction or gum hygiene in the presence of gross gum pathology (Group A) had their oral anticoagulation discontinued two days prior to the procedure which was carried out only if the INR was 1.5 or less on the day of the procedure. Patients who needed dental fillings or gum hygiene in the absence of gross gum pathology (Group B) continued their anticoagulation therapy and had these procedures completed provided the INR was 3.0 or less. The main outcome measured were valve thrombosis, thromboembolism and excessive bleeding requiring hospitalization and/or blood transfusion. In Group A, 240 procedures were carried out; 212 dental extractions and 28 dental hygiene in the presence of gross gum pathology. They had a brief period of under-anticoagulation (3-7 days) to an INR of 1.5 or less. In Group B, 156 procedures were performed. No patient developed valve thrombosis or thromboembolism. Two patients, both in Group A needed hospitalization for observation but no blood transfusion. This management plan was easy to implement. Patients needed one extra visit to the anticoagulation clinic within one week of the procedure. It was both safe and effective.

    Antiphospholipid syndrome (APS), a leading entity in acquired thrombophilia, is characterized by recurrent thrombosis, morbidity in pregnancy and presence of antiphospholipid antibodies (APA). Although the etiopathogenesis is unclear, APA against negatively charged phospholipids and phospholipid-protein complexes are held responsible for the clinical picture. In case of acute thrombosis due to APS, thrombolytic therapy is not a commonly administered treatment option. Here, we present a case with acute thrombosis in the left renal artery showing partial response to thrombolytic therapy.

    The number of thrombolytic drugs for the management of acute myocardial infarction is rapidly expanding. New agents, some of which are biochemically modified versions of currently available thrombolytics, will soon arrive in the marketplace. The pharmacologic differences of the new drugs are the basis for clinical differences such as enhanced clot lysis and prolonged elimination half-life. Ultimately, these features may result in improved infarct artery patency and patient survival.

    Patients receiving radiation therapy due to oral cancer develop complications such as hyposalivation, mucositis, oral infections, dental hypersensitivity and caries. Mouthrinses can alleviate some of these problems. To investigate the in vitro antimicrobial properties and cytotoxicity of an experimental mouthrinse. The mouthrinse contained 30% hexylene glycol (glycerine), 7% potassium nitrate and 0.025% sodium fluoride. The minimal inhibitory concentration (MIC) of these ingredients and the mixture was determined for C. albicans, S. aureus and S. mutans over 24 hours at different concentrations. The MICs of two commercial mouthrinses, Corsodyl and Plax, were also determined using the same organisms. All mouthrinses were then tested to determine the percentage kill over 1, 2, and 3 minutes. The MICs for hexylene glycol were 10%, 30% and 10% for C. albicans, S. aureus and S. mutons respectively. Potassium nitrate and sodium fluoride had no antimicrobial effects. The MIC of Corsodyl was 0.016 mg/ml for all the test organisms. The MIC for Plax varied from 0.0002 mg/ml to 0.001 mg/ml. The kill rates for all mouthrinses were acceptable, with no statistical differences between them. The experimental mouthrinse was not toxic to human oesophageal SCC cells after 1 minute exposure. At the time of the experiment, the costs of a similar quantity of the experimental mouthrinse, Corsodyl and Plax were R5.24, R30.00 and R10.00 respectively. The experimental mouthrinse was cost-effective and proved to have an antimicrobial effect and could be used safely to alleviate oral infections, desensitize teeth, improve oral hygiene and control dental caries in cancer patients after radiation therapy.

    Deep vein thrombosis (DVT) is of serious mortality and morbidity, which often happens in inpatients and especially with the postoperative population [1]. The golden standard to diagnose DVT is venography, which relies on complicated imaging modalities requiring to be injected in a vein below the clot invasively and ionizing procedures that employing xray imaging to show where and how the DVT blocks. The near-infrared spectroscopy (NIRS) is recently found to be an intriguing and potential method detecting DVT in clinics. It has been reported recently that employing NIRS to diagnose DVT. Arteriosclerosis obliterans (ASO), local extremities manifestations of systemic atherosclerosis, usually cause thrombosis and the reduction of distal blood flow. Thrombolytic therapy is to use exogenous activator to activate the dissolution system, which can dissolve intracoronary thrombus. Here we attempt to monitor the DVT and ASO patients during the whole procedure of thrombolytic treatment, then compare the data with those DVT and ASO patients did not take treatments and normal population. 8 DVT and 9 ASO patients and 12 normal subjects were recruited to take the measurements of concentration variation of oxy- and deoxy-hemoglobins (Δ[HbO2] and Δ[Hb]) by NIRS-based thrombosis monitor. Thereinto, 5 DVT and 6 ASO patients has taken the thrombolytic treatment, and the data for the periods before treatment, during treatment, and after treatment were extracted for analysis. We found that Δ[HbO2] fluctuates and even decreases in DVT and ASO patients. After the thrombolytic therapy, Δ[HbO2] increases about 45% and converge to the curves of normal subjects. And the Δ[Hb] emerges the similar trends, except for the rising trend in the beginning and the downtrend after thrombolytic therapy. The findings indicated NIRS has big potential in clinical monitoring of DVT and ASO patients and offering reliable and quantitative evaluation of thrombolytic therapy outcomes.

    Carnitine deficiency is known to occur in chronic hemodialysis; however, the effect of continuous renal replacement therapy (CRRT) on carnitine homeostasis has not been studied. We hypothesized that children receiving CRRT are at risk for deficiency because of continuous removal, absent intake, decreased production, and comorbidities related to critical illness. Records of patients with acute kidney injury receiving CRRT at Children's National Health System between 2011 and 2014 were reviewed for total carnitine (TC), free carnitine (FC), feeding modality, severity of illness, and survival outcome. The proportion of carnitine-deficient patients at baseline, 1, 2, and ≥3 weeks on CRRT were compared by chi-square, and relationships with other variables assessed by Pearson's correlation and logistic regression. The study group included 42 CRRT patients, age 7.9 + 1.1 years. At baseline, 30.7% and 35.7% of patients were TC and FC deficient. Within 1 week, 64.5% (P = 0.03) and 70% (P = 0.03) were TC and FC deficient, and prevalence of deficiency increased to 80% (P = 0.01) and 90% (P = 0.008) by 2 weeks; 100% of patients were TC and FC deficient after being on CRRT for ≥3 weeks (P = 0.005 and P = 0.01, respectively, vs. baseline). TC and FC levels negatively correlated with days on CRRT (r = -0.39, P = 0.001 and r = -0.35, P = 0.005). Patients with TC and FC deficiency had 5.9 and 4.9 greater odds of death than those with normal levels (P = 0.02 and P = 0.03). Carnitine is significantly and rapidly depleted with longer time on CRRT, and carnitine deficiency is associated with increased mortality. Consequences of deficiency and benefits of supplementation in the pediatric CRRT population should be investigated.

    Introduction: In the past few years many trials have evaluated the use of maintenance therapy in the treatment of NSCLC stage IV. Both switch as well as continuation maintenance show an improved PFS and overall survival. HRQoL data was only partially published. The aim of this article is to review the published effects of maintenance therapy on HRQoL. Methods: Two PubMed searches were performed using the terms: “maintenance therapy and NSCLC” and “maintenance therapy and NSCLC and HRQoL”. The published data was compared, analysed and evaluated. Results: 272 articles were found dealing with maintenance therapy, and of these 85 articles were found regarding maintenance therapy and HRQoL in NSCLC. Maintenance therapy showed no negative impact on HRQoL but failed to show a real benefit. Some symptoms showed positive trends during maintenance therapy. HRQoL can be used to select patients for maintenance therapy. Conclusions: Maintenance therapy is very safe, improves PFS and OS without impairing HRQoL. Although a positive impact on general QoL could not be demonstrated this is possibly due to the mode of evaluating HRQoL. Patient reported outcomes should be simplified and examined for a longer period of time. PMID:26035509

    Nonagenarians are under-represented in thrombolytic trials for acute ischemic stroke (AIS). The effectiveness of intravenous thrombolytics in nonagenarians in terms of safety and outcome is not well established. We used a multinational registry to identify patients aged 90 years or older with good baseline functional status who presented with AIS. Differences in outcomes-disability level at 90 days, frequency of symptomatic intracerebral hemorrhage (sICH), and mortality-between patients who did and did not receive thrombolytics were assessed using multivariable logistic regression, adjusted for prespecified prognostic factors. Coarsened exact matching (CEM) was utilized before evaluating outcome by balancing both groups in the sensitivity analysis. We identified 227 previously independent nonagenarians with AIS; 122 received intravenous thrombolytics and 105 did not. In the unmatched cohort, ordinal analysis showed a significant treatment effect (adjusted common odds ratio [OR]: .61, 95% confidence interval [CI]: .39-.96). There was an absolute difference of 8.1% in the rate of excellent outcome in favor of thrombolysis (17.4% versus 9.3%; adjusted ratio: .30, 95% CI: .12-.77). Rates of sICH and in-hospital mortality were not different. Similarly, in the matched cohort, CEM analysis showed a shift in the primary outcome distribution in favor of thrombolysis (adjusted common OR: .45, 95% CI: .26-.76). Nonagenarians treated with thrombolytics showed lower stroke-related disability at 90 days than those not treated, without significant difference in sICH and in-hospital mortality rates. These observations cannot exclude a residual confounding effect, but provide evidence that thrombolytics should not be withheld from nonagenarians because of age alone.

  7. Aerosol therapy in patients receiving noninvasive positive pressure ventilation.

    2012-04-01

    In selected patients, noninvasive positive pressure ventilation (NIPPV) with a facemask is now commonly employed as the first choice for providing mechanical ventilation in the intensive care unit (ICU). Aerosol therapy for treatment of acute or acute-on-chronic respiratory failure in this setting may be delivered by pressurized metered-dose inhaler (pMDI) with a chamber spacer and facemask or nebulizer and facemask. This article reviews the host of factors influencing aerosol delivery with these devices during NIPPV. These factors include (1) the type of ventilator, (2) mode of ventilation, (3) circuit conditions, (4) type of interface, (5) type of aerosol generator, (6) drug-related factors, (7) breathing parameters, and (8) patient-related factors. Despite the impediments to efficient aerosol delivery because of continuous gas flow, high inspiratory flow rates, air leaks, circuit humidity, and patient-ventilator asynchrony, significant therapeutic effects are achieved after inhaled bronchodilator administration to patients with asthma and chronic obstructive pulmonary disease. Similarly to invasive mechanical ventilation, careful attention to the technique of drug administration is required to optimize therapeutic effects of inhaled therapies during NIPPV. Assessment of the patient's ability to tolerate a facemask, the level of respiratory distress, hemodynamic status, and synchronization of aerosol generation with inspiratory airflow are important factors contributing to the success of aerosol delivery during NIPPV. Further research into novel delivery methods, such as the use of NIPPV with nasal cannulae, could enhance the efficiency, ease of use, and reproducibility of inhalation therapy during noninvasive ventilation.

    Vaginal dilation therapy is advocated after pelvic radiotherapy to prevent stenosis (abnormal narrowing of the vagina), but can be uncomfortable and psychologically distressing. To assess the benefits and harms of different types of vaginal dilation methods offered to women treated by pelvic radiotherapy for cancer. Searches included the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 5), MEDLINE (1950 to June week 2, 2013), EMBASE (1980 to 2013 week 24) and CINAHL (1982 to 2013). Comparative data of any type, which evaluated dilation or penetration of the vagina after pelvic radiotherapy treatment for cancer. Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. We found no trials and therefore analysed no data. We identified no studies for inclusion in the original review or for this update. However, we felt that some studies that were excluded warranted discussion. These included one randomised trial (RCT), which showed no improvement in sexual scores associated with encouraging women to practise dilation therapy; a recent small RCT that did not show any advantage to dilation over vibration therapy during radiotherapy; two non-randomised comparative studies; and five correlation studies. One of these showed that objective measurements of vaginal elasticity and length were not linked to dilation during radiotherapy, but the study lacked power. One study showed that women who dilated tolerated a larger dilator, but the risk of objectivity and bias with historical controls was high. Another study showed that the vaginal measurements increased in length by a mean of 3 cm after dilation was introduced 6 to 10 weeks after radiotherapy, but there was no control group; another case series showed the opposite. Three recent studies showed less stenosis associated with prophylactic dilation after radiotherapy. One small case series suggested that dilation years after radiotherapy might restore the

    Osteoporosis is a well-known complication of thyrotoxicosis. Prolonged subclinical hyperthyroidism due to L-thyroxine treatment has been associated with reduced bone mass and thus with the potential risk of premature development of osteoporosis. The aim of this study was to assess the effect of a chronic L-thyroxine suppressive treatment on bone mineral density (BMD) in a group of premenopausal women. Forty consecutive patients (mean age +/- SE = 40.95 +/- 1.56 years) affected by non-toxic goiter underwent bone mineral densitometry (dual energy X-ray absorptiometry; DEXA) of the lumbar spine (L1-L4) and right femoral neck. At the time of the study the patients had been under thyroid stimulating hormone (TSH) suppressive therapy for 74.95 +/- 10.34 months (range 17-168 months). Baseline levels of free thyroxine (fT4), free triiodothyronine (fT3), TSH, calcium and phosphorus were measured and correlated with BMD. The age of starting, duration of treatment, main daily dose, cumulative dose of treatment and body mass index (BMI) were also correlated with BMD. Statistical analysis was performed by multiple linear regression. BMD among female patients was not significantly different from that of the general population matched for age and sex. With the use of the regression model, no significant correlation was found between BMD and the variables considered. In conclusion, our data suggest that L-thyroxine suppressive therapy, if carefully carried out and monitored, has no significant effect on bone mass.

    Background Many vaginal dilator therapy guidelines advocate routine vaginal dilation during and after pelvic radiotherapy to prevent stenosis (abnormal narrowing of the vagina). The UK Gynaecological Oncology Nurse Forum recommend dilation “three times weekly for an indefinite time period”. The UK patient charity Cancer Backup advises using vaginal dilators from two to eight weeks after the end of radiotherapy treatment. Australian guidelines recommend dilation after brachytherapy “as soon as is comfortably possible” and “certainly within four weeks and to continue for three years or indefinitely if possible”. However, dilation is intrusive, uses health resources and can be psychologically distressing. It has also caused rare but very serious damage to the rectum. Objectives To review the benefits and harms of vaginal dilation therapy associated with pelvic radiotherapy for cancer. Search methods Searches included the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 4), MEDLINE (1950 to 2008), EMBASE (1980 to 2008) and CINAHL (1982 to 2008). Selection criteria Any comparative randomised controlled trials (RCT) or data of any type which compared dilation or penetration of the vagina after pelvic radiotherapy treatment for cancer. Data collection and analysis The review authors independently abstracted data and assessed risk of bias. We analysed the mean difference in sexual function scores and the risk ratio for non-compliance at six weeks and three months in single trial analyses. No trials met the inclusion criteria. Main results Dilation during or immediately after radiotherapy can, in rare cases, cause damage and there is no persuasive evidence from any study to demonstrate that it prevents stenosis. Data from one RCT showed no improvement in sexual scores in women who were encouraged to practice dilation. Two case series and one comparative study using historical controls suggest that dilation might be

    To determine the utility of local thrombolysis in the treatment of acute renal arterial occlusion. We used local thrombolytic treatment in a female patient, aged 76, with 72 h of anuria, right lumbar and flank pain. She had a 3-year history of ischemic heart disease and atrial fibrillation controlled with digital treatment. Also, she was nephrectomized on the left side 33 years ago for lithiasic pyonephrosis. A normal right urinary tract was demonstrated with ultrasound examination, KUB radiography and retrograde pyelography. The next step was diagnostic abdominal angiography and local thrombolytic treatment with streptokinase. Thrombolysis with streptokinase was successful following 72 h of renal artery occlusion. After 24 months the patient is doing well. Local intra-arterial thrombolysis is the treatment of choice in renal artery occlusion.

    Cyclophosphamide continues to have an important role in the treatment of renal disease, including nephrotic syndrome and lupus nephritis, despite known complications of gonadotoxicity and potential infertility in both male and female patients. It is important that the physician recommending this therapy mitigates the effect of the drug on fertility by adhering to recommendations on dosing limits and offering fertility-preserving strategies. In addition to well-established methods, such as sperm banking and embryo cryopreservation, advances in reproductive technology have yielded strategies such as oocyte cryopreservation, resulting in more fertility-preserving options for the pediatric patient. Despite these advances, there continues to be a significant barrier to referral and access to sperm banks and fertility specialists. These issues are further complicated by ethical issues associated with the treatment of pediatric patients. In this review we explore the development of recommended dosing limits and include a discussion of the available fertility-preserving methods, strategies for increasing access to fertility specialists, and the ethical considerations facing the pediatric healthcare provider.

  13. Should pediatric patients with hyperlipidemia receive drug therapy?

    PubMed

    Bhatnagar, Deepak

    2002-01-01

    Hyperlipidemia is now established as a major risk factor for causation of coronary heart disease (CHD) in adults; however, there is much debate on the level of coronary risk at which lipid-lowering drugs should be used. These issues of possible harm or lack of benefit from long-term use of lipid-lowering therapy, and cost effectiveness, are also pertinent in the pediatric setting. Evidence from several countries indicates that children have an increasing prevalence of obesity, hyperlipidemia and type 2 diabetes mellitus. Children who have high serum lipids 'track' these increased levels into adulthood. In some countries there is a trend to screen children for hypercholesterolemia. Family history itself is a poor discriminator in determining which children need to be screened and treated. Estimation of apolipoprotein B and/or apolipoprotein E genotype can improve prediction. Measuring high density lipoprotein cholesterol also helps, but obesity appears to be the best marker for screening children at high risk. These considerations should not cloud the need for case finding and treatment of children with genetic disorders. Low fat diets have been shown to be well tolerated and effective in children; however, there are no major long-term studies demonstrating harm or benefit in those on lipid-lowering drugs. Nevertheless, concerns regarding the psychological effect and the theoretical metabolic effects of long-term lipid lowering remain. Lipid-lowering drugs should be generally restricted to children with genetic disorders of lipid metabolism. Children with diabetes mellitus, hypertension or nonlipid-related inherited disorders leading to premature CHD in adults should be treated with diet, and with lipid-lowering drugs when they reach adulthood. Children with secondary hyperlipidemia should be assessed individually. A number of drugs and nutriceuticals are available for use in children, but only a few drugs are licensed for use in children.

    Abstract In patients with venous thromboembolism (VTE), the outcome during the course of anticoagulant therapy may differ according to the patient’s sex. We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to compare the rate of VTE recurrences, major bleeding, and mortality due to these events according to sex. As of August 2013, 47,499 patients were enrolled in RIETE, of whom 24,280 (51%) were women. Women were older, more likely presented with pulmonary embolism (PE), and were more likely to have recent immobilization but less likely to have cancer than men. During the course of anticoagulation (mean duration: 253 d), 659 patients developed recurrent deep vein thrombosis (DVT), 576 recurrent PE, 1368 bled, and 4506 died. Compared with men, women had a lower rate of DVT recurrences (hazard ratio [HR]: 0.78; 95% confidence interval [CI]: 0.67–0.91), a similar rate of PE recurrences (HR: 0.98; 95% CI: 0.83–1.15), a higher rate of major bleeding (HR: 1.21; 95% CI: 1.09–1.35), and higher mortality due to PE (HR: 1.24; 95% CI: 1.04–1.47). On multivariable analysis, any influence of sex on the risk for recurrent DVT (HR: 0.88; 95% CI: 0.75–1.03), major bleeding (HR: 1.10; 95% CI: 0.98–1.24), or fatal PE (HR: 1.01; 95% CI: 0.84–1.22) was no longer statistically significant. In conclusion, women had fewer DVT recurrences and more bleeds than men during the course of anticoagulation. These differences were not due to sex, but very likely to other patient characteristics more common in female patients and differences in treatment choice. PMID:25398066

    We investigated the frequency and characteristics of intracranial hemorrhage (ICH), factors associated with risk of ICH, and outcomes post-ICH overall and by randomized treatment. We identified patients in ARISTOTLE with ICH who received ≥1 dose of study drug (n=18,140). ICH was adjudicated by a central committee. Cox regression models were used to identify factors associated with ICH. ICH occurred in 174 patients; most ICH events were spontaneous (71.2%) versus traumatic (28.8%). Apixaban resulted in significantly less ICH (0.33%/year), regardless of type and location, than warfarin (0.80%/year). Independent factors associated with increased risk of ICH were enrollment in Asia or Latin America, older age, prior stroke/transient ischemic attack, and aspirin use at baseline. Among warfarin-treated patients, the median (25th, 75th) time from most recent international normalized ratio (INR) to ICH was 13 (6, 21) days. Median INR prior to ICH was 2.6 (2.1, 3.0); 78.5% of patients had a pre-ICH INR <3.0. After ICH, the modified Rankin scale at discharge was ≥4 in 55.7%, and mortality at 30 days was 43.3%. No difference was observed in the rates of all-cause death post-ICH, regardless of treatment. ICH occurred at a rate of 0.80%/year with warfarin regardless of INR control and 0.33%/year with apixaban, and was associated with high short-term morbidity and mortality. This highlights the clinical relevance of reducing ICH by using apixaban rather than warfarin and avoiding concomitant aspirin, especially in patients with older age.

    Objectives: We describe the frequency and types of drug therapy problems (DTPs), and interventions carried out to resolve them, among a cohort of HIV-infected patients on ART in Jos, Nigeria. Methods: A prospective pharmacists’ intervention study was conducted between January and August 2012 at the outpatient HIV clinic of the Jos University Teaching Hospital (JUTH). Pharmacists identified DTPs and made recommendations to resolve them. The main outcome measures were number of DTPs encountered, interventions proposed and acceptance rate of recommendations. Results: A total of 42,416 prescriptions were dispensed to 9339 patients during the eight months study. A total of 420 interventions (Intervention rate of 1 per 100 prescriptions) were made to resolve DTPs in 401 (4.3%) patients with a mean age of 41 (SD=10) years, and made up of 73% females. DTPs encountered were drug omission (n=89, 21.2%), unnecessary drug (n=55, 13.1%) and wrong drug indication (n=55, 13.1%). Recommendations offered included; Addition of another drug to the therapy (n=87, 20.7%), rectification of incomplete prescriptions (n=85, 20.2%), change of drug or dosage (n=67, 16.0%), and discontinuation of the offending drug (n=59, 14.0%). A total of 389 (93%) out of 420 of the recommendations were accepted. In all, 50.4% (212) of the problematic prescriptions were changed and dispensed, 22.2% (89) were clarified and dispensed, while wrong identities were corrected in 11.7% (49). However, 7.5% (30) prescriptions were dispensed as prescribed, 5.2% (21) were not dispensed, and 3% (12) were unresolved. Conclusion: Our findings suggest that pharmacists-initiated interventions can ameliorate DTPs in patients receiving ART given the high intervention acceptance rate recorded. The implication of this finding is that pharmacists with requisite training in HIV pharmacotherapy are an excellent resource in detecting and minimizing the effect of antiretroviral drug-related errors.

  17. Modulation by the noble gas argon of the catalytic and thrombolytic efficiency of tissue plasminogen activator.

    Argon has been shown to provide cortical as well as, under certain conditions, subcortical neuroprotection in all models so far (middle cerebral artery occlusion, trauma, neonatal asphyxia, etc.). This has led to the suggestion that argon could be a cost-efficient alternative to xenon, a metabolically inert gas thought to be gold standard in gas pharmacology but whose clinical development suffers its little availability and excessive cost of production. However, whether argon interacts with the thrombolytic agent tissue plasminogen activator, which is the only approved therapy of acute ischemic stroke to date, still remains unknown. This latter point is not trivial since previous data have clearly demonstrated the inhibiting effect of xenon on tPA enzymatic and thrombolytic efficiency and the critical importance of the time at which xenon is administered, during or after ischemia, in order not to block thrombolysis and to obtain neuroprotection. Here, we investigated the effect of argon on tPA enzymatic and thrombolytic efficiency using in vitro methods shown to provide reliable prediction of the in vivo effects of both oxygen and the noble inert gases on tPA-induced thrombolysis. We found that argon has a concentration-dependent dual effect on tPA enzymatic and thrombolytic efficiency. Low and high concentrations of argon of 25 and 75 vol% respectively block and increase tPA enzymatic and thrombolytic efficiency. The possible use of argon at low and high concentrations in the treatment of acute ischemic stroke if given during ischemia or after tPA-induced reperfusion is discussed as regards to its neuroprotectant action and its inhibiting and facilitating effects on tPA-induced thrombolysis. The mechanisms of argon-tPA interactions are also discussed.

    We investigate the impact of dutasteride on prostate specific antigen (PSA) and prostate volume in men receiving testosterone (T) therapy. Twenty-three men on stable dose T therapy were randomised to receive either dutasteride or placebo for 12 months. Serum levels of PSA, T and dihydrotestosterone (DHT) and responses to the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ) questionnaires were determined at baseline and at 3, 6, 9 and 12 months. Prostate volume (PV) was measured using transrectal ultrasound (TRUS) at baseline and again after 12 months. A total of 22 men (mean age 57.3) completed the study, with 11 men receiving placebo and 11 receiving dutasteride. Men receiving dutasteride had a significant decrease in PSA (-0.46 ± 0.81 ng ml(-1) ; P = 0.04) and in PV (-6.65 ± 11.0%; P = 0.03) from baseline over 12 months. DHT decreased significantly for men on dutasteride compared with men receiving placebo (P = 0.02). When compared with men who received placebo, men who received dutasteride demonstrated nonsignificant trends towards decreased PSA (-0.46 versus 0.21 ng ml(-1) ; P = 0.11), PV (-6.65% versus 3.4%; P = 0.08) and MSHQ scores (-10.2 versus 5.6; P = 0.06). Dutasteride reduces PSA and PV for men on T therapy, but perhaps less so than in men without T therapy.

    The purpose of this study was to investigate how premature infants' oxygen saturation changed in response to music therapy while they were receiving endotracheal suctioning. A convenience sample of 30 premature infants was selected from three neonatal intensive care units. A one-group repeated measures design was adopted for this study. The oxygen saturation of all subjects was first measured while they were receiving endotracheal suctioning during a four-hour control period with regular care. Then, four hours after the control period was completed, an experimental period began in which the music " Transitions " was played. One minute before suctioning, the level of oxygen saturation was measured to provide the baseline data. During a period of 30 minutes after suctioning, the oxygen saturation was recorded every minute to analyze the clinical effects of music therapy. The results showed that premature infants receiving music therapy with endotracheal suctioning had a significantly higher SPO(2); than that when not receiving music therapy (p <.01), and the level of oxygen saturation returned to the baseline level faster than when they did not receive music therapy (p <.01). Accordingly, it is hoped that giving appropriate music therapy as developmental care to premature infants when performing any nursing intervention may enhance not only the quality of nursing care but also quality of the infant's life.

    Hepatitis C virus infection is highly prevalent among people who inject drugs. Opioid substitution therapy, the standard treatment for opioid dependence, provides an excellent opportunity for the treatment of hepatitis C virus infection due to the close and regular contact between patients and clinicians. However, there is little research on the impact of opioid substitution therapy on the prevalence of the hepatitis C virus at a national level. This paper describes the protocol for the Epidemiology of Hepatitis C Virus Infection among People Receiving Opioid Substitution Therapy (ECHO) study. The aim of this study is to estimate the national prevalence and incidence of hepatitis C virus infection among people receiving opioid substitution therapy in Germany and to describe factors associated with hepatitis C treatment uptake and seroconversion. An observational, longitudinal, multicentre study is being conducted between 2014 and 2016 in a representative sample of approximately 2500 people receiving opioid substitution therapy from about 100 clinicians providing opioid substitution therapy in Germany. Data will be collected during routine patient care and by means of patient and clinician questionnaires at baseline and 12-month follow-up. Stratified sampling will be performed to obtain a representative sample of clinicians providing opioid substitution therapy. The strata will be constructed based on the distribution of the total sample of clinicians providing opioid substitution therapy in Germany according to German Federal State and the number of patients per clinician. Opioid substitution therapy may be an important strategy to prevent the spread of hepatitis C virus in opioid dependent populations, but its effectiveness may be diminished by our limited understanding of factors associated with treatment uptake and seroconversion. The present study will provide important information for developing strategies to address hepatitis C virus-related disease burden in

    Focused ultrasound (FUS) shows great promise for use in the area of transcranial therapy. Currently dependent on MRI for monitoring, transcranial FUS would benefit from a real-time technique to monitor acoustic emissions during therapy. A polyvinylidene fluoride receiver with an active area of 17.8 mm (2) and a film thickness of 110 mum was constructed. A compact preamplifier was designed to fit within the receiver to improve the receiver SNR and allow the long transmission line needed to remove the receiver electronics outside of the MRI room. The receiver was compared with a 0.5 mm commercial needle hydrophone and focused and unfocused piezoceramics. The receiver was found to have a higher sensitivity than the needle hydrophone, a more wideband response than the piezoceramic, and sufficient threshold for detection of microbubble emissions. Sonication of microbubbles directly and through a fragment of human skull demonstrated the ability of the receiver to detect harmonic bubble emissions, and showed potential for use in a larger scale array. Monitoring of disruption of the blood-brain barrier in rats showed functionality in vivo and the ability to detect subharmonic, harmonic, and wideband emissions during therapy. The receiver shows potential for monitoring acoustic emissions during treatments and providing additional parameters to assist treatment planning. Future work will focus on developing a multi-element array for transcranial treatment monitoring.

    The most dangerous adverse effect of opioids is respiratory depression. Naloxone is used to reverse this, although in patients receiving long-term opioid therapy it can cause acute opioid withdrawal and opioid-refractory pain. To determine if naloxone is appropriately administered to patients receiving long-term opioid therapy. This retrospective case series based on chart reviews systematically identified patients over one year in a district general hospital. All patients aged 18 years or older receiving long-term opioid therapy admitted to medicine, surgery or the high dependency unit who were administered naloxone during their admission were included. A total of 1206 patient drug administration records were reviewed. Sixteen patients receiving long-term opioid therapy were administered naloxone. Twelve of these did not have opioid-induced respiratory depression and four did not have respiratory rate and oxygen saturations documented in the medical notes. All naloxone doses administered were higher than those recommended by national guidelines for this patient group. No patient receiving long-term opioid therapy who was administered naloxone had evidence of respiratory depression. More thorough assessment and documentation are needed. Verbal and physical stimulation as well as oxygenation should be considered prior to naloxone administration; this should be followed by close observation, hydration, renal function tests and opioid dose review.

    OBJECTIVES--To determine what proportion of oncology patients receiving conventional medical treatment also use complementary treatments; to assess which complementary treatments are the most popular and to assess patients' motivation for using them; to evaluate associated advantages and risks. DESIGN--Postal screening questionnaire followed by semistructured interview. SETTING--Two hospitals in inner London. SUBJECTS--600 unselected oncology patients aged 18 or over who had known their diagnosis of cancer for at least three months. MAIN OUTCOME MEASURES--Prevalence and demography of use of complementary therapies; patients' motivation and expectations of complementary therapies; areas of satisfaction and dissatisfaction associated with conventional and complementary therapies. RESULTS--415 (69%) patients returned the questionnaire. 16% had used complementary therapies. The most popular were healing, relaxation, visualisation, diets, homoeopathy, vitamins, herbalism, and the Bristol approach. Patients using complementary therapies tended to be younger, of higher social class, and female. Three quarters used two or more therapies. Therapies were mostly used for anticipated antitumour effect. Ill effects of diets and herb treatments were described. Satisfaction with both conventional and complementary therapies was high, although diets often caused difficulties. Patients using complementary therapies were less satisfied with conventional treatments, largely because of side effects and lack of hope of cure. Benefits of complementary therapies were mainly psychological. CONCLUSIONS--A sizeable percentage of patients receiving conventional treatments for cancer also use complementary therapies. Patient satisfaction with complementary therapies, other than dietary therapies, was high even without the hoped for anticancer effect. Patients reported psychological benefits such as hope and optimism. PMID:8038672

    Uterine-preserving therapy with progesterone may be used in young women with endometrial cancer who desire fertility preservation. Such therapy delays definitive treatment with hysterectomy. We examined the use and safety of progestational therapy in young women with endometrial cancer. The primary outcome of the analysis was overall survival. We identified women ≤49 years of age with stage I endometrial cancer in the National Cancer Database from 2004 through 2014. Women treated with hormonal therapy with or without hysterectomy were compared to women treated with hysterectomy. After propensity score weighting, overall survival was examined using proportional hazards models. A total of 23,231 patients, including 872 (3.8%) women treated with hormonal therapy were identified. Use of hormonal therapy was 2.4% (95% confidence interval, 1.8-3.3%) in 2004 and increased over time to 5.9% (95% confidence interval, 5.0-6.9%) by 2014 (P < .0001). Use of hormonal therapy decreased with older age, higher substage, and increasing grade. Black women were more likely to receive hormonal therapy while Medicaid recipients were less likely to receive hormonal therapy. The 5-year survival for patients treated with hormonal therapy was 96.4% (95% confidence interval, 94.3-98.0%) compared to 97.2% (95% confidence interval, 96.9-97.4%) for hysterectomy. In a multivariable model, women treated with hormonal therapy were 92% (hazard ratio, 1.92; 95% confidence interval, 1.15-3.19) more likely to die compared to women who underwent primary hysterectomy. When stratified by stage, hormonal therapy was associated with increased mortality in women with stage IB and I-not otherwise specified tumors but not for stage IA neoplasms. Use of progestational therapy is increasing. Its use was associated with decreased survival, particularly in women with stage IB tumors. Copyright © 2017 Elsevier Inc. All rights reserved.

    Purpose: This study sought to quantify the risk of radiation pneumonitis (RP) in Hodgkin lymphoma (HL) patients receiving mediastinal radiation therapy (RT) and to identify predictive factors for RP. Methods and Materials: We identified 75 patients with newly diagnosed HL treated with mediastinal RT and 17 patients with relapsed/refractory HL treated with mediastinal RT before or after transplant. Lung dose-volumetric parameters including mean lung dose and percentage of lungs receiving 20 Gy were calculated. Factors associated with RP were explored by use of the Fisher exact test. Results: RP developed in 7 patients (10%) who received mediastinal RT as part of initial therapy (Radiation Therapy Oncology Group Grade 1 in 6 cases). A mean lung dose of 13.5 Gy or greater (p = 0.04) and percentage of lungs receiving 20 Gy of 33.5% or greater (p = 0.009) significantly predicted for RP. RP developed in 6 patients (35%) with relapsed/refractory HL treated with peri-transplant mediastinal RT (Grade 3 in 4 cases). Pre-transplant mediastinal RT, compared with post-transplant mediastinal RT, significantly predicted for Grade 3 RP (57% vs. 0%, p = 0.015). Conclusions: We identified threshold lung metrics predicting for RP in HL patients receiving mediastinal RT as part of initial therapy, with the majority of cases being of mild severity. The risk of RP is significantly higher with peri-transplant mediastinal RT, especially among those who receive pre-transplant RT.

    Aims: To investigate variables before sorafenib therapy on the clinical outcomes in hepatocellular carcinoma (HCC) patients receiving sorafenib and to further assess and compare the predictive performance of continuous parameters using time-dependent receiver operating characteristics (ROC) analysis. Patients and methods: A total of 225 HCC patients were analyzed. We retrospectively examined factors related to overall survival (OS) and progression free survival (PFS) using univariate and multivariate analyses. Subsequently, we performed time-dependent ROC analysis of continuous parameters which were significant in the multivariate analysis in terms of OS and PFS. Total sum of area under the ROC in all time points (defined as TAAT score) in each case was calculated. Results: Our cohort included 175 male and 50 female patients (median age, 72 years) and included 158 Child-Pugh A and 67 Child-Pugh B patients. The median OS time was 0.68 years, while the median PFS time was 0.24 years. On multivariate analysis, gender, body mass index (BMI), Child-Pugh classification, extrahepatic metastases, tumor burden, aspartate aminotransferase (AST) and alpha-fetoprotein (AFP) were identified as significant predictors of OS and ECOG-performance status, Child-Pugh classification and extrahepatic metastases were identified as significant predictors of PFS. Among three continuous variables (i.e., BMI, AST and AFP), AFP had the highest TAAT score for the entire cohort. In subgroup analyses, AFP had the highest TAAT score except for Child-Pugh B and female among three continuous variables. Conclusion: In continuous variables, AFP could have higher predictive accuracy for survival in HCC patients undergoing sorafenib therapy. PMID:28261338

Objective To study the effects of hormone therapy on brain activation patterns during verbal memory in postmenopausal women. Design A randomized, double-blind placebo-controlled cross-over study was performed. Setting A tertiary care university medical center. Participants Ten healthy postmenopausal women (age range 50-60 years) were recruited from the local community. Interventions Women were randomized to the order they received combined hormone therapy, 5 ug ethinyl estradiol and 1 mg norethindrone acetate, and placebo. Volunteers received hormone therapy or placebo for 4 weeks, followed by a one month washout period, and then received the other treatment for 4 weeks. An fMRI was performed at the end of each 4 week treatment utilizing a verbal memory task. Main Outcome Measure Brain activation patterns were compared between hormone therapy and placebo. Results Hormone therapy was associated with increased activation in left middle/superior frontal cortex (BA 6,9), medial frontal cortex and dorsal anterior cingulate (BA 24,32), posterior cingulate (BA 6), and left inferior parietal (BA 40) during memory encoding. All regions were significant at p ≤ 0.05 with correction for multiple comparisons. Conclusions Hormone therapy increased neural activation in frontal and parietal areas in postmenopausal women during a verbal memory task. PMID:18692790

    Background and Purpose: The projected increase in persons with advanced heart failure and associated costs warrant the examination of exercise in patients receiving inotropic therapy. Literature supports the use of exercise and inotropic therapy in the treatment of patients with advanced heart failure. The purposes of this paper are to illustrate the use of exercise prescription and outcomes assessment with a 6-minute walk test in a patient with acute decompensated heart failure receiving tailored therapy with dobutamine and to discuss potential relationships resulting in observed improvements. Case Description: A 67-year old man was admitted to an acute care hospital with acute decompensated heart failure for tailored medical therapy including dobutamine. The patient received 14 days of tailored medical therapy, of which 12 days included exercise training by a physical therapist. Outcomes: Functional outcomes showed a clinically significant improvement in distance walked and improvement in the cardiorespiratory response. The improvement in estimated peak oxygen consumption was 7% greater than that predicted to be from tailored medical therapy. Discussion: Exercise was safely provided to a patient hospitalized with advanced heart failure on continuous inotropic therapy. The 6-minute walk test was effectively used to prescribe exercise and examine patient outcomes. PMID:21637393

    Low-level exercise thallium testing is useful in identifying the high-risk patient after acute myocardial infarction (AMI). To determine whether this use also applies to patients after thrombolytic treatment of AMI, 64 patients who underwent early thrombolytic therapy for AMI and 107 patients without acute intervention were evaluated. The ability of both the electrocardiogram and thallium tests to predict future events was compared in both groups. After a mean follow-up of 374 days, there were 25 and 32% of cardiac events in the 2 groups, respectively, with versus without acute intervention. These included death, another AMI, coronary artery bypass grafting or angioplasty with 75% of the events occurring in the 3 months after the first infarction. The only significant predictors of outcome were left ventricular cavity dilatation in the intervention group and ST-segment depression and increased lung uptake in the nonintervention group. The sensitivity of exercise thallium was 55% in the intervention group and 81% in the nonintervention group (p less than 0.05). Therefore, in patients having thrombolytic therapy for AMI, nearly half the events after discharge are not predicted by predischarge low-level exercise thallium testing. The relatively weak correlation of outcome with unmasking ischemia in the laboratory before discharge may be due to an unstable coronary lesion or rapid progression of disease after the test. Tests considered useful for prognostication after AMI may not necessarily have a similar value if there has been an acute intervention, such as thrombolytic therapy.

    Accumulation of fibrin in the blood vessels usually results in thrombosis, leading to myocardial infarction and other cardiovascular diseases. For thrombolytic therapy, microbial fibrinolytic enzymes have now attracted much more attention than typical thrombolytic agents because of the expensive prices and the undesirable side effects of the latter. The fibrinolytic enzymes were successively discovered from different microorganisms, the most important among which is the genus Bacillus from traditional fermented foods. The physiochemical properties of these enzymes have been characterized, and their effectiveness in thrombolysis in vivo has been further identified. Therefore, microbial fibrinolytic enzymes, especially those from food-grade microorganisms, have the potential to be developed as functional food additives and drugs to prevent or cure thrombosis and other related diseases.

    Brain abscess formation is a rare complication of intracranial endovascular treatment. To our knowledge, all previous reports of brain abscess formation have been associated with treatments involving the introduction of foreign materials. A 75-year-old man was admitted to hospital for acute stroke. Cerebral angiography revealed occlusion of the left middle cerebral artery (MCA) at the origin of the M2 segment. Intra-arterial thrombolytic therapy was administered but a hemorrhagic event occurred during this process. A brain CT scan revealed a hematoma extending from the left basal ganglia to the left frontal lobe and expansion of the infarct in the left MCA territory. A brain abscess at the hemorrhagic site developed 3 months after symptom onset. This is the first report of a patient with brain abscess formation following intra-arterial thrombolytic treatment. It is important to ensure aseptic technique during endovascular procedures irrespective of the involvement of foreign materials. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Patients with arterial disease receiving antiplatelet agents may develop venous thromboembolism (VTE) and need anticoagulant therapy, although concomitant use of these drugs may increase bleeding risk. We analyzed RIETE data and compared clinical outcomes depending on decision to discontinue or maintain antiplatelet therapy at VTE diagnosis. Consecutive patients with acute VTE were enrolled in RIETE. Only patients receiving antiplatelet therapy at baseline were included in this analysis. Primary outcomes were: rate of subsequent ischemic events, major bleeding or death during anticoagulation course. 1178 patients who received antiplatelet drugs at VTE diagnosis were included. Antiplatelet therapy was discontinued in 62% of patients. During anticoagulation course, patients also receiving antiplatelet therapy had higher rates of lower limb amputations (2.28 vs. 0.21 events per 100 patients-years; p<0.01), any ischemic events (5.7 vs. 2.28 events per 100 patients-years; p<0.05) or death (23.6 vs. 13.9 deaths per 100 patients-years; p<0.01). No differences in the rate of major bleeding or recurrent VTE were revealed. In matched analysis, patients on antiplatelet therapy were found to have a significantly higher rate of limb amputations (odds ratio: 15.3; 95% CI: 1.02-229) and an increased number of composite outcomes including all-cause deaths, arterial and VTE events (odds ratio: 1.46; CI: 1.03-2.06), with no differences in major bleeding rate. Concomitant anticoagulant and antiplatelet therapy in patients with VTE and arterial disease is not associated with increased risk for bleeding, recurrent VTE or death. The worse outcome observed in patients who continued antiplatelet therapy requires further investigations. Copyright © 2014 European Federation of Internal Medicine. Published by Elsevier B.V.

    Purpose: To investigate whether single nucleotide polymorphisms (SNPs) in the ataxia telangiectasia mutated (ATM) gene are associated with survival in patients with esophageal squamous cell carcinoma (ESCC) receiving radiation therapy or chemoradiation therapy or surgery only. Methods and Materials: Four tagSNPs of ATM were genotyped in 412 individuals with clinical stage III or IV ESCC receiving radiation therapy or chemoradiation therapy, and in 388 individuals with stage I, II, or III ESCC treated with surgery only. Overall survival time of ESCC among different genotypes was estimated by Kaplan-Meier plot, and the significance was examined by log-rank test. The hazard ratios (HRs) and 95% confidence intervals (CIs) for death from ESCC among different genotypes were computed by a Cox proportional regression model. Results: We found 2 SNPs, rs664143 and rs664677, associated with survival time of ESCC patients receiving radiation therapy. Individuals with the rs664143A allele had poorer median survival time compared with the rs664143G allele (14.0 vs 20.0 months), with the HR for death being 1.45 (95% CI 1.12-1.89). Individuals with the rs664677C allele also had worse median survival time than those with the rs664677T allele (14.0 vs 23.5 months), with the HR of 1.57 (95% CI 1.18-2.08). Stratified analysis showed that these associations were present in both stage III and IV cancer and different radiation therapy techniques. Significant associations were also found between the SNPs and locosregional progression or progression-free survival. No association between these SNPs and survival time was detected in ESCC patients treated with surgery only. Conclusion: These results suggest that the ATM polymorphisms might serve as independent biomarkers for predicting prognosis in ESCC patients receiving radiation therapy.

    Thrombolytic treatment for acute myocardial infarction increases the risk of subsequent reocclusion of the infarct related artery. The efficacy and safety of repeat thrombolytic treatment was assessed in 31 patients treated with streptokinase (n = 13) or tissue plasminogen activator (n = 18) a median of five days (1-716) after the first infusion. The indication for readministration was prolonged chest pain with new ST segment elevation. Efficacy was assessed by infarct artery patency at angiography at a median of eight days after readministration in 22 patients and by non-invasive criteria in 23 patients (reperfusion was deemed to be likely if serum creatine kinase was not increased or reached a peak less than 12 hours after infarction). Angiography showed patency of 70% of the infarct arteries after readministration of streptokinase and of 75% after tissue plasminogen activator. The corresponding patency rates assessed noninvasively were 73% and 75%. Reinfarction was prevented in nine (29%) patients. Allergic reactions occurred in four of eight patients who received streptokinase twice (plasmacytosis and acute reversible renal failure developed in one patient). Two patients had major bleeding and two minor bleeding, all after tissue plasminogen activator, and one of them died of cerebral haemorrhage. Repeat thrombolytic treatment results in late patency rates similar to the rates after the initial administration. Allergic reactions were common in those treated twice with streptokinase.

    The consensus statement for standard of care in SMA recommends multidisciplinary medical care including physical therapy (PT) services. To date there are no reports regarding the implementation of these recommendations and the type of care or services received by individuals with SMA. The purpose of this study is to describe the PT services received by individuals with SMA. Interviews were conducted with patients or their caregivers at the Pediatric Neuromuscular Clinical Research (PNCR) Network sites from October 2011 to September 2012. Questions included information about clinical status of the patient, sociodemographic profile of the patient or caregiver, and PT services received in the past year, including the setting, frequency, duration and type of PT, and therapies administered by caregivers. Eighty-six percent of 105 participants reported receiving PT services, some in multiple settings: 62% in the neuromuscular clinic, 38% at school, 34% at home, and 13% in an outpatient clinic. Greater frequency of PT services received was associated with younger age and inability to walk, but not SMA type. This is the first multicenter study documenting PT services received by patients with SMA. Further research is needed to better understand the impact of PT services on the natural history of SMA.

    Purpose. The study aimed to investigate the effectiveness of antipyretic therapy on mortality in critically ill patients with sepsis requiring mechanical ventilation. Methods. In this study, we employed the multiparameter intelligent monitoring in intensive care II (MIMIC-II) database (version 2.6). All patients meeting the criteria for sepsis and also receiving mechanical ventilation treatment were included for analysis, all of whom suffer from fever or hyperthermia. Logistic regression model and R language (R version 3.2.3 2015-12-10) were used to explore the association of antipyretic therapy and mortality risk in critically ill patients with sepsis receiving mechanical ventilation treatment. Results. A total of 8,711 patients with mechanical ventilator were included in our analysis, and 1523 patients died. We did not find any significant difference in the proportion of patients receiving antipyretic medication between survivors and nonsurvivors (7.9% versus 7.4%, p = 0.49). External cooling was associated with increased risk of death (13.5% versus 9.5%, p < 0.001). In our regression model, antipyretic therapy was positively associated with mortality risk (odds ratio [OR]: 1.41, 95% CI: 1.20–1.66, p < 0.001). Conclusions. The use of antipyretic therapy is associated with increased risk of mortality in septic ICU patients requiring mechanical ventilation. External cooling may even be deleterious. PMID:28386165

    The benefits of family interventions for families having to cope with serious mental health problems are well documented but routine implementation of these interventions is often problematic. Despite a wealth of research on the clinical outcomes of such interventions, very little is known about families' subjective perceptions of receiving them. This study reports the findings of a phenomenological enquiry into the lived experience of 10 families who received Behavioural Family Therapy (BFT) as part of a training initiative in the West Midlands Health Region of the UK. The results show that families were very satisfied with the intervention. They reported reductions in the levels of stress within the family, reduction in levels of carer burden, enhanced communication skills and a positive sense of empowerment. They attributed these changes to receiving BFT. The majority of families viewed mental health professionals and services more favourably compared to their experiences before receiving BFT. This is an important finding for service providers, commissioners and mental heath workers.

    Background The intake of soy isoflavones among women with breast cancer has become a public health concern, because these compounds have weak estrogenic effects. There is little clinical evidence about their safety for patients with breast cancer who are receiving adjuvant endocrine therapy. Methods For patients who underwent surgery for breast cancer between August 2002 and July 2003 and who were receiving adjuvant endocrine therapy, we examined associations between dietary intake of soy isoflavones and recurrence of breast cancer and death. We measured dietary intake of soy isoflavones at baseline using a validated food frequency questionnaire. We estimated hazard ratios (HRs) and 95% confidence intervals (CIs) by means of multivariable Cox proportional hazards regression models. We further stratified the analyses by hormonal receptor status and endocrine therapy. Results The median follow-up period for the 524 patients in this study was 5.1 years. Among premenopausal patients, the overall death rate (30.6%) was not related to intake of soy isoflavones (HR = 1.05, 95% CI 0.78–1.71 for the highest quartile [> 42.3 mg/day] v. the lowest quartile [< 15.2 mg/day], p for trend = 0.87). Relative to post-menopausal patients in the lowest quartile of soy isoflavone intake, the risk of recurrence for post-menopausal patients in the highest quartile was significantly lower (HR = 0.67, 95% CI 0.54–0.85, p for trend = 0.02). Inverse associations were observed in patients with estrogen and progesterone receptor positive disease and those receiving anastrozole therapy. Interpretation High dietary intake of soy isoflavones was associated with lower risk of recurrence among post-menopausal patients with breast cancer positive for estrogen and progesterone receptor and those who were receiving anastrozole as endocrine therapy.

    To ascertain whether steroid therapy evokes dentin hypersensitivity (DH)-like tooth pain, we performed a study based on compelling evidence from patients receiving steroid therapy. An exploratory study was conducted using a questionnaire for 220 patients prescribed steroids who attended the Department of Hematology and Rheumatology of Tohoku University Hospital. Group comparisons between patients with and without steroid pulse therapy were analysed by statistical means. In this study, any DH-like tooth pain that commenced subsequent to steroid treatment was defined as steroid-derived (SD) tooth pain. The prevalence of SD tooth pain was 17.7% (39/220 patients). SD tooth pain was triggered in many vital teeth by cold and/or hot water (84.2% and 23.7%, respectively) with the pain characterised as continuous, in contrast to typical DH tooth pain. SD tooth pain was significantly more frequent in pulse therapy patients than in non-pulse therapy patients (p < 0.05). Logistic regression analysis adjusted for age and sex showed similar results (odds ratio = 3.74, p = 0.013). Moreover, a positive correlation was observed between the steroid dose and pain score (ρ = 0.642). Dose reduction or discontinuation of steroid therapy relieved SD tooth pain in all cases. Thus, steroid therapy can evoke DH-like tooth pain during treatment. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

    Canada's Best Practice Recommendations for Stroke Care state that a minimum of one hour per day of each of the relevant core therapies be provided to patients admitted for inpatient rehabilitation. We examined whether this standard was met on a single, specialized stroke rehabilitation unit and if amount of therapy was an independent contributor to functional improvement. One-hundred and twenty-three, consecutive patients admitted to a 30-bed stroke rehabilitation program over a 6-month period with the confirmed diagnosis of stroke, were included. Workload measurement data were used to estimate the amount of therapy that patients received from core therapists during their inpatient stay. A multivariable model to predict Functional Independence Measure (FIM) gains achieved was also developed using variables that were significantly correlated with functional gain on univariate analysis. On average, patients received 37 min of active therapy from both physiotherapists (PT) and occupational therapists (OT) and 13 min from speech-language pathologists per day. Admission FIM, length of stay, total OT and PT therapy time (hrs) were significantly correlated with FIM gain. In the final model, which explained 35% of the variance, admission FIM score and total amount of occupational therapy (OT) emerged as significant predictors of FIM gain. Patients admitted to a specialized rehabilitation unit received an average of 37 min a day engaged in therapeutic activities with both occupational and physical therapists. Although this value did not reach the standard of one hour, total amount of OT time contributed significantly to gains in FIM points during hospital stay.

    To report a case of slipped capital femoral epiphysis in a young patient with Turner syndrome (TS) receiving growth hormone therapy and to emphasize the importance of keeping this orthopedic condition in mind during management of this patient group. Clinical, laboratory, and radiographic findings are presented, and risk factors for slipped capital femoral epiphysis are discussed. A child with TS presented for medical assessment because of a limp but with no history of trauma or febrile illness. Growth hormone therapy had been administered for 1 year because of her short stature. Physical examination and pelvic radiography of the patient showed the presence of bilateral slipped capital femoral epiphysis. She underwent bilateral pinning in situ, and growth hormone therapy was terminated. At follow-up after more than 2 years, no sequelae were noted. Patients with TS are at high risk for developing certain orthopedic conditions, such as slipped capital femoral epiphysis. Furthermore, slipped capital femoral epiphysis is a known complication of growth hormone therapy in growing children. A limp, hip pain, knee pain, or thigh pain might be a symptom of slipped capital femoral epiphysis in patients with TS, especially those receiving growth hormone therapy. Prompt recognition and treatment of this condition are important for prevention of sequelae.

    Eosinophilic myocarditis is a rare form of myocardial inflammation that is characterized by the infiltration of eosinophilic cells into the myocardium. The clinical symptoms of eosinophilic myocarditis are similar to those of acute coronary syndrome, and eosinophilic myocarditis sometimes occurs in combination with bronchial asthma. We herein present a case of eosinophilic myocarditis in which additional time was required to make a definitive diagnosis because the patient received steroid therapy. The diagnosis of eosinophilic myocarditis is challenging, especially when a patient has other inflammatory diseases, such as bronchial asthma. We should pay attention to the possibility that steroid therapy may mask the presentation of eosinophilic myocarditis. PMID:28090045

    Veterans are increasingly using complementary and integrative health (CIH) therapies to manage chronic pain and other troubling symptoms that significantly impair health and quality of life. The Department of Veterans Affairs (VA) is exploring ways to meet the demand for access to CIH, but little is known about Veterans’ perceptions of the VA’s efforts. To address this knowledge gap, we conducted interviews of 15 inpatients, 8 receiving palliative care, and 15 outpatients receiving CIH in the VA. Pain was the precipitating factor in all participants’ experience. Participants were asked about their experience in the VA and their opinions about which therapies would most benefit other Veterans. Participants reported that massage was well-received and resulted in decreased pain, increased mobility, and decreased opioid use. Major challenges were the high ratio of patients to CIH providers, the difficulty in receiving CIH from fee-based CIH providers outside of the VA, cost issues, and the role of administrative decisions in the uneven deployment of CIH across the VA. If the VA is to meet its goal of offering personalized, proactive, patient-centered care nationwide then it must receive support from Congress while considering Veterans’ goals and concerns to ensure that the expanded provision of CIH improves outcomes.

    The underlying molecular mechanisms of adverse drug events (ADEs) associated with cancer therapy drugs may overlap with their antineoplastic mechanisms. In a previous study, we developed an ADE-based tumor stratification framework (known as ADEStrata) with a case study of breast cancer patients receiving aromatase inhibitors, and demonstrated that the prediction of per-patient ADE propensity simultaneously identifies high-risk patients experiencing poor outcomes. In this study, we aim to evaluate the ADEStrata framework with a different tumor type and chemotherapy class – ovarian cancer treated with platinum chemotherapeutic drugs. We identified a cohort of ovarian cancer patients receiving cisplatin (a standard platinum therapy) from The Cancer Genome Atlas (TCGA) (n=156). We demonstrated that somatic variant prioritization guided by known ADEs associated with cisplatin could be used to stratify patients treated with cisplatin and uncover tumor subtypes with different clinical outcomes.

  9. Characteristics of Symptomatic Intracranial Hemorrhage in Patients Receiving Non-Vitamin K Antagonist Oral Anticoagulant Therapy

    PubMed Central

    2015-01-01

    Objectives The first non-vitamin K antagonist oral anticoagulant (NOAC) introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH) occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH. Methods We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014. Results ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years). Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset. Conclusion Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg) and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy. PMID:26171862

    Dose escalation is now the standard of care for the treatment of prostate cancer with radiation therapy. However, the rectum tends to be the dose-limiting structure when treating prostate cancer, given its close proximity. Early and late toxicities can occur when the rectum receives large doses of radiation therapy. New technologies allow for prevention of these toxicities. In this review, we examine the evidence that supports various dose constraints employed to prevent these rectal injuries from occurring. We also examine the use of intensity-modulated radiation therapy and how this compares to older radiation therapy techniques that allow for further sparing of the rectum during a radiation therapy course. We then review the literature on endorectal balloons and the effects of their daily use throughout a radiation therapy course. Tissue spacers are now being investigated in greater detail; these devices are injected into the rectoprostatic fascia to physically increase the distance between the prostate and the anterior rectal wall. Last, we review the use of systemic drugs, specifically statin medications and antihypertensives, as well as their impact on rectal toxicity. PMID:28814898

    We studied serum calcium, phosphorus, alkaline phosphatase (ALP), thyroid hormones (total thyroxine [TT4], free thyroxine [FT4], thyroid-stimulating hormone [TSH]), parathyroid hormone (PH), and osteocalcine levels in children with epilepsy who had been receiving long-term carbamazepine (CBZ) therapy to determine whether there was any effect of CBZ therapy on these hormones. The study included 18 patients with epilepsy receiving CBZ and 16 healthy age-matched controls. The age ranged from 4-18 years (11.26 +/- 3.59 years) and 4.5-17 years (11.16 +/- 3.13 years) in the study and control group, respectively. The duration of CBZ use was between 10 months-5 years (3.12 +/- 1.09 years). When comparing the results we did not find any significant difference in serum calcium, phosphorus, ALP, osteocalcine and TSH and PH levels between the groups (p >.05). However, serum TT4 and FT4 levels were found to be significantly lower in the study group than those of control group (p <.05). However, we observed no clinical signs of hypothyroidism in all subjects. To these findings we suggest that serum thyroid hormone levels should be monitored in children receiving long-term CBZ therapy.

    To assess and compare the oral manifestations of HIV-infected paediatric patients undergoing ART (anti-retroviral therapy) and those not undergoing ART. A cross-sectional study was conducted amongst the 5-12 years old, HIV positive children (receiving and not receiving ART) registered at Nireekshana ART centre, Hyderabad and HIV negative children enrolled in a nearby school. HIV-related oral lesions were diagnosed according to WHO criteria. Information on age, gender, place of residence (urban/rural), socio-economic status, duration of HIV infection, duration of ART therapy, use of traditional medicine, presence of HIV-related systemic disease was recorded. CD4+ cell count was also determined for each subject. Chi-square test, stepwise multiple linear and logistic regression were used for statistical analysis. For all tests, confidence interval and p value were set at 95 % and p ≤ 0.05, respectively. Twelve percent and 21.3 % of the study participants were on short-term and long-term ART (Group I), respectively. A greater proportion of HIV patients receiving treatment had CD4+ cell counts of more than 750 cells/mm(3). Nearly 81.3 % of HIV patients receiving long-term therapy did not have any oral lesions. Around half of the participants not receiving treatment suffered from HIV-related oral lesions. The best predictors for presence of oral lesions were socio-economic status, group (ART treatment), duration of HIV infection and CD4+ cell count. The results of the present study demonstrated that ART proved to be effective in reducing the prevalence of HIV-related oral lesions.

    A 57-year-old woman with mycosis fungoides developed blisters within cutaneous plaques while receiving PUVA therapy and topical nitrogen mustard. Direct and indirect immunofluorescence studies showed the findings of bullous pemphigoid. Her bullous disease was controlled after cessation of these therapies and institution of prednisone and methotrexate. During the 5 months following completion of a course of electron-beam therapy, she has been free of the cutaneous manifestations of both diseases. Previous instances of PUVA-related pemphigoid have occurred in psoriatics. The role of ultraviolet light in the induction of pemphigoid is discussed, particularly with regard to its possible interaction with the altered skin of psoriasis or mycosis fungoides. Some of the rare cases of bullous mycosis fungoides might actually have represented ultraviolet-unmasked bullous pemphigoid.

    In a study of 29 patients who were receiving or had received interferon alpha 2b (IFN-alpha 2b) as maintenance therapy for multiple myeloma, antibodies were detected in 58% (17/29) of patients measured by a solid-phase enzyme-linked immunosorbent assay (ELISA). Only 7/17 patients who were positive for antibody in the ELISA had neutralising antibody to IFN-alpha 2b, measured by virus growth inhibition. These patients comprised six who were receiving IFN-alpha 2b at the time of assessment and one who had finished treatment. Among patients who were receiving the cytokine, four had progressive disease, one was in complete remission and one in partial remission. Neutralising activity was also detected to natural human leucocyte IFN-alpha in the same patients. Two patients who were positive for neutralising antibody remain in remission and are continuing to receive IFN-alpha 2b. These two patients have since lost their neutralising titre. No neutralising antibody to IFN-alpha 2b or natural human leucocyte IFN-alpha was detected in serum from six normal donors. The data suggest that neutralising antibody formation in patients with multiple myeloma is not responsible for relapse in patients receiving IFN-alpha 2b. The transient nature of neutralising antibody production in patients who remain in remission suggests that this response to IFN-alpha 2b is not associated with memory B cells. PMID:7917911

    The aim of this prospective study was to identify the most effective and safest regimen among different thrombolytic treatment strategies. The best treatment strategies for prosthetic valve thrombosis have been controversial. Transesophageal echocardiography-guided thrombolytic treatment was administered to 182 consecutive patients with prosthetic valve thrombosis in 220 different episodes (156 women; mean age, 43.2 ± 13.06 years) between 1993 and 2009 at a single center. These regimens chronologically included rapid (Group I), slow (Group II) streptokinase, high-dose (100 mg) tissue plasminogen activator (t-PA) (Group III), a half-dose (50 mg) and slow infusion (6 h) of t-PA without bolus (Group IV), and a low dose (25 mg) and slow infusion (6 h) of t-PA without bolus (Group V). The endpoints were thrombolytic success, in-hospital mortality, and nonfatal complication rates. The overall success rate in the whole series was 83.2%; it did not differ significantly among Groups I through V (68.8%, 85.4%, 75%, 81.5%, and 85.5%, respectively; p = 0.46). The overall complication rate in the whole series was 18.6%. Although the overall complication rate was similar among Groups I through IV (37.5%, 24.4 %, 33.3%, and 29.6%, respectively; p > 0.05 for each comparison), it was significantly lower in Group V (10.5%, p < 0.05 for each). The combined rates of mortality and nonfatal major complications were also lower in Group V than in the other groups, with all differences significant except for comparison of Groups IV and V. By multivariate analysis, the predictors of combined mortality plus nonfatal major complications were any thrombolytic therapy regimen other than Group V (odds ratios for Groups I through IV: 8.2, 3.8, 8.1, and 4.1, respectively; p < 0.05 for each) and a history of stroke/transient ischemic attack (odds ratio: 3.5, p = 0.011). In addition, there was no mortality in Group V. Low-dose slow infusion of t-PA repeated as needed without a bolus provides

    Dignity therapy is a psychosocial intervention that has been used primarily at the end of life to improve quality of life and other patient outcomes, but many individuals are unable to complete it due to health decline and death. The purpose of this study was to identify what individuals with advanced pancreatic or lung cancer with limited life expectancy, undergoing active cancer treatment describe during the dignity therapy intervention as important to them when not immediately facing end of life. Twenty patients undergoing chemotherapy for advanced cancer participated in a dignity therapy intervention study. Initial interviews were analyzed using descriptive content analysis. Family provided the overall context and background for emerging themes of defining events, accomplishments, and God's plan, which led to lessons learned, and resulted in messages of hope. Interviews were often autobiographical in nature and contained much reminiscence, consistent with dignity therapy's intent. Few participants spoke about their cancer diagnoses during the interview. This study adds unique insight into the use of dignity therapy for those still receiving active cancer treatment, different from work by others in which it was offered only at end of life. As part of supportive care, clinicians need to validate the importance of family to those with advanced cancer and to provide opportunities for patients to share what they have learned throughout life and to impart messages of hope to those closest to them.

    Background The purpose of this study was to document outcomes following withdrawal of a single inhaler (step-down) in chronic obstructive pulmonary disease (COPD) patients on triple therapy (long-acting muscarinic antagonist and a combination of long-acting β2-agonists and inhaled corticosteroid), which a common treatment strategy in clinical practice. Methods Through a retrospective observational study, COPD patients receiving triple therapy over 2 years (triple group; n=109) were compared with those who had undergone triple therapy for at least 1 year and subsequently, over 9 months, initiated inhaler withdrawal (step-down group, n=39). The index time was defined as the time of withdrawal in the stepdown group and as 1 year after the start of triple therapy in the triple group. Results Lung function at the index time was superior and the previous exacerbation frequency was lower in the stepdown group than in the triple group. Step-down resulted in aggravating disease symptoms, a reduced overall quality of life, decreasing exercise performance, and accelerated forced expiratory volume in 1 second (FEV1) decline (54.7±15.7 mL/yr vs. 10.7±7.1 mL/yr, p=0.007), but there was no observed increase in the frequency of exacerbations. Conclusion Withdrawal of a single inhaler during triple therapy in COPD patients should be conducted with caution as it may impair the exercise capacity and quality of life while accelerating FEV1 decline.

    Purpose Androgen deprivation therapy is associated with fracture risk in men with prostate cancer. We assessed the effects of toremifene, a selective estrogen receptor modulator, on fracture incidence in men receiving androgen deprivation therapy during a 2-year period. Materials and Methods In this double-blind, placebo controlled phase III study 646 men receiving androgen deprivation therapy for prostate cancer were assigned to toremifene (80 mg by mouth daily) and 638 were assigned to placebo. Subjects were followed for 2 years. The primary study end point was new vertebral fractures. Secondary end points included fragility fractures, bone mineral density and lipid changes. Results The 2-year incidence of new vertebral fractures was 4.9% in the placebo group vs 2.5% in the toremifene group, a significant relative risk reduction of 50% (95% CI –1.5 to 75.0, p = 0.05). Toremifene significantly increased bone mineral density at the lumbar spine, hip and femoral neck vs placebo (p <0.0001 for all comparisons). There was a concomitant decrease in markers of bone turnover (p <0.05 for all comparisons). Toremifene also significantly improved lipid profiles. Venous thromboembolic events occurred more frequently with toremifene than placebo with 7 subjects (1.1%) in the placebo group experiencing a venous thromboembolic event vs 17 (2.6%) in the toremifene group. Other adverse events were similar between the groups. Conclusions Toremifene significantly decreased the incidence of new vertebral fractures in men receiving androgen deprivation therapy for prostate cancer. It also significantly improved bone mineral density, bone turnover markers and serum lipid profiles. PMID:20723926

    The ratio of the area under the free (unbound) concentration-time curve to minimum inhibitory concentration (fAUC/MIC) was proposed to be the pharmacokinetic/pharmacodynamic index most strongly linked to the antibacterial effect of colistin against Acinetobacter baumannii. A retrospective study of patients who received colistin to treat pneumonia caused by extensively drug-resistant (XDR) A. baumannii over a 4-year period was performed to assess the impact of the colistin MIC on mortality. A total of 227 patients were included in the analysis. The 7-day and 14-day mortality rates of patients with XDR A. baumannii pneumonia receiving colistin therapy were 15.0% and 23.8%, respectively. In the multivariate analysis, Acute Physiology and Chronic Health Evaluation (APACHE) II score, days from index culture to first dose of colistin, underlying tumour and septic shock at presentation were independent predictors of mortality in patients with XDR A. baumannii pneumonia receiving colistin therapy. In the univariate analysis, the colistin dose based on ideal body weight (IBW) correlated with patient outcome. Therefore, the use of IBW appeared to be more appropriate to calculate the colistin dosage. In addition, these results highlight the clinical significance of colistin MIC in patients with XDR A. baumannii pneumonia receiving colistin therapy. Although MICs were in the 'susceptible' range, patients infected with isolates with high colistin MICs showed a poorer clinical response rate than patients infected with isolates with low colistin MICs. Further clinical studies are needed to evaluate the roles of colistin MIC for predicting mortality in XDR A. baumannii pneumonia with a high colistin MIC.

    Purpose The aims of this systematic review were to determine, in patients receiving cancer therapy, the prevalence of clinical oral fungal infection and fungal colonization, to determine the impact on quality of life and cost of care, and to review current management strategies for oral fungal infections. Methods Thirty-nine articles that met the inclusion/exclusion criteria were independently reviewed by two calibrated reviewers, each using a standard form. Information was extracted on a number of variables, including study design, study population, sample size, interventions, blinding, outcome measures, methods, results, and conclusions for each article. Areas of discrepancy between the two reviews were resolved by consensus. Studies were weighted as to the quality of the study design, and recommendations were based on the relative strength of each paper. Statistical analyses were performed to determine the weighted prevalence of clinical oral fungal infection and fungal colonization. Results For all cancer treatments, the weighted prevalence of clinical oral fungal infection was found to be 7.5% pretreatment, 39.1% during treatment, and 32.6% after the end of cancer therapy. Head and neck radiotherapy and chemotherapy were each independently associated with a significantly increased risk for oral fungal infection. For all cancer treatments, the prevalence of oral colonization with fungal organisms was 48.2% before treatment, 72.2% during treatment, and 70.1% after treatment. The prophylactic use of fluconazole during cancer therapy resulted in a prevalence of clinical fungal infection of 1.9%. No information specific to oral fungal infections was found on quality of life or cost of care. Conclusions There is an increased risk of clinically significant oral fungal infection during cancer therapy. Systemic antifungals are effective in the prevention of clinical oral fungal infection in patients receiving cancer therapy. Currently available topical antifungal

    Introduction The aim was to investigate the frequency of neurological adverse events in patients with rheumatoid arthritis (RA) and spondylarthropathies (SpA) treated with tumor necrosis factor (TNF) α antagonists. Methods Seventy-seven patients eligible for anti-TNFα therapy were evaluated. There were 36 patients with RA, 41 with SpA [24 psoriatic arthritis (PsA) and 17 with ankylosing spondylitis (AS)]. All patients had a complete physical and neurological examination. Brain and cervical spine magnetic resonance imaging (MRI) and neurophysiological tests were performed in all patients before the initiation of anti-TNFα therapy and after a mean of 18 months or when clinical symptoms and signs indicated a neurological disease. Exclusion criteria included hypertension, diabetes mellitus, dyslipidemia, heart arrhythmias, atherothrombotic events, vitamin B12 and iron deficiency, head and neck trauma and neurological surgeries. Results Two patients did not receive anti-TNFα therapy because brain MRIs at baseline revealed lesions compatible with demyelinating diseases. Thus, 75 patients received anti-TNFα (38 infliximab, 19 adalimumab and 18 etanercept). Three patients developed neurological adverse events. A 35-year-old man with PsA after 8 months of infliximab therapy presented with paresis of the left facial nerve and brain MRI showed demyelinating lesions. Infliximab was discontinued and he was treated with pulses of corticosteroids recovering completely after two months. The second patient was a 45-year-old woman with RA who after 6 months of adalimumab therapy presented with optic neuritis. The third patient was a 50-year-old woman with AS, whom after 25 months of infliximab therapy, presented with tingling and numbness of the lower extremities and neurophysiological tests revealed peripheral neuropathy. In both patients anti-TNF were discontinued and they improved without treatment after 2 months. The rest of our patients showed no symptoms and MRIs

    A variety of evidence from laboratory and animal studies suggests that lithium has neurotrophic and cytoprotective properties, and may ameliorate or prevent some disease states. We investigated whether such a protective effect can be observed in human psychiatric patients receiving lithium therapy. We carried out a retrospective chart review of 1028 adult psychiatric male and female outpatients attending four lithium clinics in metropolitan New York City. Patients were divided into two groups based on lithium usage, and the prevalence of neurological and cardiovascular disorders was compared. The main outcome measures were the occurrence in the two patient groups of a variety of neurological disorders and myocardial infarction. Odds ratios were calculated to assess the risk of having a disorder for patients receiving lithium compared to patients not receiving lithium: for seizures, the odds ratio was 0.097; for amyotrophic lateral sclerosis, the odds ratio was 0.112; for dementia not otherwise specified, the odds ratio was 0.112; and for myocardial infarction, the odds ratio was 0.30. Logistical regression analysis showed that lithium treatment is a significant negative predictive factor in the prevalence of each of these disease states, when age, duration of clinic attendance, and use of anti-psychotic medications are taken into account. Our results show that patients receiving regular lithium treatment have a reduced prevalence of some neurological disorders and myocardial infarctions. One possible explanation of these results is that a protective effect of lithium observed in laboratory and animal studies may also be present in human patients receiving regular lithium therapy.

    The aim of this study was to analyze risk factors for nosocomial infection (NI) in patients receiving extracorporeal membrane oxygenation (ECMO) support. Clinical NI data were collected from patients who received ECMO support therapy, and analyzed retrospectively. Among 75 ECMO patients, 20 were found to have developed NI (infection rate 26.7%); a total of 58 pathogens were isolated, including 43 strains of gram-negative bacteria (74.1%) and 15 strains of gram-positive bacteria (25.9%). Multi-drug resistant strains were highly concentrated and were mainly shown to be Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Incidence of NI was related to the duration of ECMO support therapy and the total length of hospital stay, and the differences were statistically significant (P<.05). A prolonged period of ECMO support extended the hospital stay, but it did not increase the mortality rate. However, an elevated level of lactic acid increased the mortality rate in this study population. ECMO-associated secondary NIs correlated significantly with the length of hospital stay and with the duration of ECMO support. Therefore, to reduce the incidence of ECMO-associated NIs, preventive strategies that aim to shorten the duration of ECMO support therapy and avoid lengthy hospitalization should be applied, wherever possible.

    Because of its advantageous depth-dose relationship, proton radiotherapy is an emerging treatment modality for patients with liver cancer. Although the proton dose distribution conforms to the target, healthy tissues throughout the body receive low doses of stray radiation, particularly neutrons that originate in the treatment unit or in the patient. The aim of this study was to calculate the effective dose from stray radiation and estimate the corresponding risk of second cancer fatality for a patient receiving proton beam therapy for liver cancer. Effective dose from stray radiation was calculated using detailed Monte Carlo simulations of a double-scattering proton therapy treatment unit and a voxelized human phantom. The treatment plan and phantom were based on CT images of an actual adult patient diagnosed with primary hepatocellular carcinoma. For a prescribed dose of 60 Gy to the clinical target volume, the effective dose from stray radiation was 370 mSv; 61% of this dose was from neutrons originating outside of the patient while the remaining 39% was from neutrons originating within the patient. The excess lifetime risk of fatal second cancer corresponding to the total effective dose from stray radiation was 1.2%. The results of this study establish a baseline estimate of the stray radiation dose and corresponding risk for an adult patient undergoing proton radiotherapy for liver cancer and provide new evidence to corroborate the suitability of proton beam therapy for the treatment of liver tumors.

    This mixed methods pilot study evaluated the effects of the creative arts therapy (CAT) on the quality of life (QOL) of children receiving chemotherapy. A 2-group, repeated measures randomized design compared CAT with a volunteer's attention (n = 16). Statistical analysis of the randomized controlled phase of the study suggested an improvement in the following areas after the CAT: parent report of child's hurt (P = .03) and parent report of child's nausea (P = .0061). A nonrandomized phase, using a different instrument showed improved mood with statistical significance on the Faces Scale (P < .01), and patients were more excited (P < .05), happier (P < .02), and less nervous (P < .02). Provider focus groups revealed positive experiences. Case studies are included to exemplify the therapeutic process. With heightened interest in complementary therapy for children with cancer, future research with a larger sample size is needed to document the impact of incorporating creative arts into the healing process.

    AIM To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. RESULTS The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients’ GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

    The purpose of this descriptive, correlational study was to ascertain if there is a relationship between social support and the nutritional status of patients receiving radiation therapy for cancer. The data collection instruments used included the Norbeck Social Support Questionnaire (NSSQ), the Personal Characteristics Form, the abbreviated Health History, the Flow Sheet for Nutritional Data, and the Interview Schedule. For the analysis of data descriptive statistics were utilized to provide a profile of subjects, and correlational statistics were used to ascertain if there were relationships among the indicators of nutritional status and the social support variables. A convenience sample was comprised of 50 cancer patients deemed curable by radiation therapy. Findings included significant decreases in anthropometric measurements and biochemical tests during therapy. Serial assessments of nutritional status, therefore, are recommended for all cancer patients during therapy in order to plan and implement strategies for meeting the self-care requisites for food and water. No statistically significant relationships were found between the social support variables as measured by the NSSQ and the indicators of nutritional status. This suggests that nurses can assist patients by fostering support from actual and potential nutritional confidants.

    Urologic patients receiving bone-targeted therapies are at risk of developing osteonecrosis of the jaw (ONJ). ONJ has historically been associated with bisphosphonate therapy. More recently, RANK-Ligand inhibitors (denosumab) have also been used to reduce the risk of skeletal-related events in patients who have advanced cancers with bone metastases. More than 65% of men with metastatic prostate cancer and nearly 75% of women with metastatic breast cancer are affected by bone metastases. The literature has described ONJ associated with bisphosphonate therapy as bisphosphonate-related osteonecrosis of the jaw (BRONJ). However, with evidence also linking the use of RANK-Ligand inhibitors with osteonecrosis of the jaw, we advocate use of the term "anti-bone resorption therapy-related osteonecrosis of the jaw" (ABRT-ONJ). The term "medication-related osteonecrosis of the jaw" (MRONJ) is now becoming more widespread. There is not a universally accepted definition of ABRT-ONJ, which may have hindered recognition and reporting of the condition. In Part I of this article, a review of current knowledge around the etiology of ABRT-ONJ and incidence data are provided. In Part II, we provide an audit of ONJ in a nurse consultant-led bone support clinic. In the article, we refer to zoledronic acid because this is the bisphosphonate of choice for use in men with prostate cancer in the United Kingdom.

    The aim of this review was to evaluate current literature for dosing recommendations for the use of antiepileptic medications in patients receiving renal replacement therapy (RRT). With the assistance of an experienced medical librarian specialized in pharmacy and toxicology, we searched MEDLINE, EMBASE, CINAHL, Web of Science, WorldCat, and Scopus through May 2016. Four hundred three articles were screened for inclusion, of which 130 were identified as potentially relevant. Micromedex® DRUGDEX as well as package inserts were used to obtain known pharmacokinetic properties and dosage adjustment recommendations in RRT if known. Data regarding antiepileptic drug use in RRT are limited and mostly consist of case reports limiting our proposed dosing recommendations. Known pharmacokinetic parameters should guide dosing, and recommendations are provided where possible. Additional studies are necessary before specific dosing recommendations can be made for most antiepileptic drugs in critically ill patients receiving RRT, specifically with newer agents.

    We prospectively studied the efficacy and adverse effects of chlorpromazine (30 mg/m2 given intravenously) plus lorazepam (0.04 mg/kg given intravenously) versus chlorpromazine alone in a controlled, double-blind, randomized, parallel-design investigation in 25 children (1.5 to 17.3 years of age) with acute lymphoblastic leukemia. Response to other antiemetics in eight children refusing random assignment to treatment was also evaluated. All children were receiving intravenous infusions of teniposide plus cytarabine, the pharmacokinetics of which were characterized for each of the one to four courses. There were no differences between the 11 patients randomly assigned to receive chlorpromazine alone and the 14 randomly assigned to receive lorazepam plus chlorpromazine in the number of emesis episodes (6.0 vs 5.9; p = 0.53), frequency of dystonic reactions (3% vs 5%), or akathisia (13 vs 10%). The only serious adverse event, symptomatic hypotension, occurred in a boy receiving chlorpromazine plus lorazepam. An exploratory pharmacodynamic analysis revealed that the only variable that correlated with vomiting was cytarabine 1 1/2-hour plasma concentration (p = 0.007). Children who received either chlorpromazine plus lorazepam or chlorpromazine alone had fewer episodes of vomiting than those who received "conventional" antiemetic therapy (6.0 vs 8.6; p = 0.01). We conclude that the severity of emesis is related to the plasma concentration of cytarabine; that intravenously administered chlorpromazine is as effective as chlorpromazine plus lorazepam in preventing chemotherapy-induced vomiting; and that the potential for adverse effects with the addition of lorazepam may be a disadvantage.

    Purpose Alternatives to cytotoxic agents are desirable for patients with HIV-associated Kaposi's sarcoma (KS). Vascular endothelial growth factor-A (VEGF-A) contributes to KS pathogenesis. We evaluated the humanized anti–VEGF-A monoclonal antibody, bevacizumab, in patients with HIV-KS. Patients and Methods Patients with HIV-KS who either experienced progression while receiving highly active antiretroviral therapy (HAART) for at least 1 month or did not regress despite HAART for at least 4 months were administered bevacizumab 15 mg/kg intravenously on days 1 and 8 and then every 3 weeks. The primary objective was assessment of antitumor activity using modified AIDS Clinical Trial Group (ACTG) criteria for HIV-KS. HIV-uninfected patients were also eligible and observed separately. Results Seventeen HIV-infected patients were enrolled. Fourteen patients had been receiving effective HAART for at least 6 months (median, 1 year). Thirteen patients had advanced disease (ACTG T1), 13 patients had received prior chemotherapy for KS, and seven patients had CD4 count less than 200 cells/μL. Median number of cycles was 10 (range, 1 to 37 cycles); median follow-up was 8.3 months (range, 3 to 36 months). Of 16 assessable patients, best tumor responses observed were complete response (CR) in three patients (19%), partial response (PR) in two patients (12%), stable disease in nine patients (56%), and progressive disease in two patients (12%). Overall response rate (CR + PR) was 31% (95% CI, 11% to 58.7%). Four of five responders had received prior chemotherapy for KS. Over 202 cycles, grade 3 to 4 adverse events at least possibly attributed to therapy included hypertension (n = 7), neutropenia (n = 5), cellulitis (n = 3), and headache (n = 2). Conclusion Bevacizumab is tolerated in patients with HIV-KS and has activity in a subset of patients. PMID:22430271

    Purpose. A case report evaluating flucytosine dosing in a critically ill patient receiving continuous renal replacement therapy. Summary. This case report outlines an 81-year-old male who was receiving continuous venovenous hemofiltration (CVVH) for acute renal failure and was being treated with flucytosine for the treatment of disseminated Cryptococcus neoformans infection. Due to patient specific factors, flucytosine was empirically dose adjusted approximately 50% lower than intermittent hemodialysis (iHD) recommendations and approximately 33% lower than CRRT recommendations. Peak and trough levels were obtained, which were supratherapeutic, and pharmacokinetic parameters were calculated. The patient experienced thrombocytopenia, likely due to elevated flucytosine levels, and flucytosine was ultimately discontinued. Conclusion. Despite conservative flucytosine dosing for a patient receiving CVVH, peak and trough serum flucytosine levels were supratherapeutic (120 μg/mL at 2 hours and 81 μg/mL at 11.5 hours), which increased drug-related adverse effects. The results indicate that this conservative dosing regimen utilizing the patient's actual body weight was too aggressive. This case report provides insight into flucytosine dosing in CVVH, a topic that has not been investigated previously. Further pharmacokinetic studies of flucytosine dosing in critically ill patients receiving CVVH are needed in order to optimize pharmacokinetic and pharmacodynamic parameters while avoiding toxic flucytosine exposure.

    Meropenem is frequently prescribed in children receiving continuous renal replacement therapy (CRRT). Fluid overload is often present in critically ill children and affects drug disposition. The purpose of this study was to develop a pharmacokinetic model to (1) evaluate target attainment of meropenem dosing regimens against P. aeruginosa in children receiving CRRT and (2) estimate the effect of fluid overload on target attainment. Clinical trial simulations were employed to evaluate target attainment of meropenem in various age groups and degrees of fluid overload in children receiving CRRT. Pharmacokinetic parameters were extracted from published literature, and 287 patients from the prospective pediatric CRRT registry database provided realistic clinical covariates including patient weight, fluid overload, and CRRT prescription characteristics. Target attainment at 40% and 75% time above the minimum inhibitory concentration was evaluated. Clinical trial simulations demonstrated that children greater than 5 years of age achieved acceptable target attainment with a dosing regimen of 20 mg/kg every 12 hours. In children less than 5, however, increased dosing of 20 mg/kg every 8 hours was needed to optimize target attainment. Fluid overload did not affect target attainment. These in silico model predictions will need to be verified in vivo in children receiving meropenem and CRRT. © 2014, The American College of Clinical Pharmacology.

    In order to describe the prevalence of hypercholesterolemia and hypertriglyceridemia in a cohort of HIV-infected children and adolescents in Latin America and to determine associations with highly active antiretroviral therapy (HAART), we performed this cross-sectional analysis within the NICHD International Site Development Initiative pediatric cohort study. Eligible children had to be at least 2 years of age and be on HAART. Among the 477 eligible HIV-infected youth, 98 (20.5%) had hypercholesterolemia and 140 (29.4%) had hypertriglyceridemia. In multivariable analyses, children receiving protease inhibitor (PI)-containing HAART were at increased risk for hypercholesterolemia [adjusted odds ratio (AOR) = 2.7, 95% confidence interval (CI) 1.3–5.6] and hypertriglyceridemia (AOR = 3.5, 95% CI 1.9–6.4) compared with children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing HAART. In conclusion, HIV-infected youth receiving PI-containing HAART in this Latin American cohort were at increased risk for hypercholesterolemia and hypertriglyceridemia compared with those receiving NNRTI-containing HAART.

    Background. Human immunodeficiency virus (HIV)–infected individuals are at increased risk of cardiovascular disease (CVD) due in part to inflammation. Statins decrease inflammation in the general population, but their effect during HIV infection is largely unknown. Methods. This is an ongoing randomized, double-blinded, placebo-controlled trial to evaluate the effect of statin therapy on inflammatory markers during HIV infection. Subjects received rosuvastatin 10 mg daily or placebo for 24 weeks. Subjects were receiving stable (>12 weeks) antiretroviral therapy and had a low-density lipoprotein (LDL) cholesterol level of ≤130 mg/dL and evidence of heightened immune activation or inflammation. This was a prespecified interim analysis. Results. A total of 147 subjects were enrolled (78% were male, 70% were black, and the median age was 47 years). By 24 weeks, LDL cholesterol levels had decreased in the statin group, compared with an increase in the placebo group (−28% vs +3.8%; P < .01). A 10% reduction in the lipoprotein-associated phospholipase A2 (Lp-PLA2) level was seen in the statin group, compared with a 2% reduction in the placebo group (P < .01). In multivariable regression, receipt of statin treatment and having a nadir CD4+ T-cell count of ≤100 cell/µL were the only statistically significant predictors of a decrease in Lp-PLA2 level. Markers of systemic inflammation did not change significantly between groups. Conclusions. Twenty-four weeks of rosuvastatin therapy significantly decreased the level of Lp-PLA2, a vascular-specific, inflammatory enzyme that predicts cardiovascular events in the general population. Statins may hold promise as a means of attenuating CVD risk in HIV-infected individuals by decreasing Lp-PLA2 levels. PMID:24415784

    To describe Australian physiotherapy and occupational therapy practice for patients who receive upper-limb Botulinum Toxin-A (BoNT-A). Anonymous online survey asking about practice experience. Convenience sample of 128 BoNT-A experienced occupational therapists and physiotherapists. The primary work setting was multidisciplinary inpatient or outpatient rehabilitation services where therapists had automatic referral to BoNT-A patients. Patients expected BoNT-A to improve functional movement, reduce hypertonicity, increase passive range, reduce pain, improve appearance and hand hygiene. Most patients were injected in multidisciplinary public hospital clinics and had median 2 pre-injection (range 0-30) and 8 post-injection (range 0-50) therapy sessions. Biceps, flexor digitorum profundus/superficialis and brachoradialis were most frequently injected. Injectors used therapist assessment information to select sites 68% of the time; only 44% of services had assessment protocols. Standardised therapy assessments examined motor performance, pain and function in that order of frequency. The greater the awareness and perceived relevance of an assessment the more often therapists used it. All therapists set goals, most collaboratively, and these mirrored patient expectations. The most common treatments were stretch, task-specific functional training, strength training and home programmes. While trends in Australian assessment, goals and treatment practice were observed, greater consistency could be achieved if therapy practice guidelines existed. The gap is exacerbated by the absence of Australian BoNT-A organisation and process of care spasticity management guidelines. This creates an environment where practice variability is inevitable. Recommendations to improve local service quality are made. © 2015 Occupational Therapy Australia.

    Background: A phase III trial demonstrated an overall survival advantage with the addition of vinflunine to best supportive care (BSC) in platinum-refractory advanced urothelial cancer. We subsequently examined the impact of an additional 2 years of survival follow-up and evaluated the influence of first-line platinum therapy on survival. Methods: The 357 eligible patients from the phase III study were categorised into two cohorts depending on prior cisplatin treatment: cisplatin or non-cisplatin. Survival was calculated using the Kaplan–Meier method. Results: The majority had received prior cisplatin (70.3%). Survival was higher in the cisplatin group (HR: 0.76; CI 95% 0.58–0.99; P=0.04) irrespective of treatment arm. Multivariate analysis including known prognostic factors (liver involvement, haemoglobin, performance status) and prior platinum administration did not show an independent effect of cisplatin. Vinflunine reduced the risk of death by 24% in the cisplatin-group (HR: 0.76; CI 95% 0.58–0.99; P=0.04) and by 35% in non-cisplatin patients (HR: 0.65; CI 95% 0.41–1.04; P=0.07). Interpretation: Differences in prognostic factors between patients who can receive prior cisplatin and those who cannot may explain the survival differences in patients who undergo second line therapy. Prior cisplatin administration did not diminish the subsequent benefit of vinflunine over BSC. PMID:24129239

    Hemorrhagic complications of thrombolytic therapy are rare but also serious and sometimes life-threatening. Liver hematoma is a very uncommon complication following thrombolytic therapy. We present a rare case of sub-capsular liver hematoma following streptokinase therapy of acute myocardial infarction as a challenging condition. This case report highlights that emergency physicians and cardiologists should be familiar with the significant and uncommon complications of thrombolytic agents, particularly streptokinase which is used generally in under- developed countries.

    Recent findings of rapid lung function decline in younger patients with moderate COPD severity suggest the need for effective early treatment. To evaluate the effectiveness of indacaterol as maintenance therapy in COPD patients not receiving other maintenance treatments. Pooled data from three randomised, placebo-controlled studies provided a population of patients with moderate-to-severe COPD not receiving maintenance treatment at baseline and who received once-daily, double-blind treatment with indacaterol 150 μg, indacaterol 300 μg or placebo. Data from an open-label tiotropium treatment arm in one study were available for comparison. Efficacy evaluations included trough FEV₁, dyspnoea (transition dyspnoea index, TDI) and health status (St George's Respiratory Questionnaire, SGRQ) at 6 months and risk of COPD exacerbations. The maintenance-naïve population comprised 232 (indacaterol 150 μg), 220 (indacaterol 300 μg) and 325 (placebo) patients, plus 156 (tiotropium) (30% of overall study population). Patients treated with indacaterol 150 and 300 μg had statistically significant improvements relative to placebo (p < 0.05) in trough FEV₁ (170 and 180 mL), TDI total score (1.27 and 1.04 points), rescue use and SGRQ total score (-6.1 and -2.5 units) at 6 months. Patients receiving tiotropium had statistically significant improvements versus placebo (p < 0.05) in trough FEV₁ (130 mL) and TDI total score (0.69 points). Exacerbations were rare and not significantly reduced by any treatment. Treatments were well tolerated. Indacaterol, given to patients with moderate-to-severe COPD not receiving other maintenance treatments, provided effective bronchodilation with significant, clinically relevant improvements in dyspnoea and health status compared with placebo.

    Background: Patient satisfaction is the most important criterion in evaluating the quality of care. Besides, its assessment in patients with severe mental disorder treated by electroconvulsive therapy (ECT) is highly appropriate. The ECT is accompanied by lower satisfaction and may exacerbate the patients’ condition. Objectives: The current study aimed to determine the effect of supportive nursing care on the satisfaction of patients receiving ECT. Patients and Methods: This randomized controlled trial was conducted in the education center of Baharan psychiatric hospital, Zahedan, Iran. Seventy hospitalized patients receiving ECT were randomly divided into two groups of control (n = 35) and intervention (n = 35).The socio-personal and Webster Satisfaction Questionnaire were used as data collection tools. The intervention group received supportive nursing care by nurses trained in informational, emotional, and physical aspects. The control group received only regular nursing care. The levels of satisfaction were measured and compared between groups, before and after the intervention. Data were analyzed using the SPSS software, and Chi-square, independent and paired t tests, as well as covariance analysis were performed. Results: The results showed similarities in socio-personal characteristics of both groups. However, there was a significant difference (P < 0.001) between the means of satisfaction in the groups, predominantly for the intervention group. In other words, a significant difference (P < 0.001) was observed between the means of satisfaction of the intervention (54.71 ± 5.27) and control (36.28 ± 7.00) groups after intervention by controlling the effect of socio-personal variables. Conclusions: Results of the current study confirmed the effect of supportive nursing care on increasing the level of satisfaction in ECT receiving patients, recommending the use of this therapeutic method.

    Thrombin generation assay (TGA) is useful as a global functional test for assessing bleeding or thrombotic risk and its modification with therapy. We investigated TGA to assess anticoagulation status compared with the international normalized ratio (INR) system in patients with primary thrombophilia receiving and not undergoing thromboprophylaxis. We studied 50 patients with at least one thrombotic event and a confirmed diagnosis of inherited thrombophilia. Thrombin generation was measured in platelet-poor plasma by calibrated automated thrombography (CAT). Patients in optimal anticoagulation (INR: 2.0-3.0) showed an endogenous thrombin potential (ETP) of 14-56% of normal and a peak of 18-55% of normal. A significant inverse relationship between INR and thrombin generation parameters (ETP, peak and velocity index) and a linear correlation for lag time was found in patients treated with vitamin-K antagonists (VKA). Receiver-operating characteristics (ROC) analysis showed that the optimal cutoff for ETP was 1600.2 nM · min (111.6% of normal, with a sensitivity of 96.6% and a specificity of 92.9%) and for the peak was 298.3 nM (112.1% of normal, with a sensitivity of 96.4% and a specificity of 100%). According to this analysis, ETP was able to identify patients with increased thrombotic and hemorrhagic risk, correlating with severe clinical complications. TGA showed excellent sensitivity and specificity for assessing anticoagulation status in patients with primary thrombophilia receiving VKA, with significant advantages with regard to INR. Clinical data strongly support ETP as a valuable indicator of thrombotic or hemorrhagic risk in patients receiving or not receiving thromboprophylaxis. Copyright © 2015 Elsevier Ltd.

    Limited data are available on ceftolozane/tazobactam dosing in patients receiving continuous renal replacement therapy (CRRT). Thus we performed a pharmacokinetic analysis of intravenous ceftolozane/tazobactam in a critically ill patient receiving CRRT at our medical center. A 47-year-old critically ill man with multidrug-resistant Pseudomonas aeruginosa pneumonia, bacteremia, and osteomyelitis was receiving ceftolozane/tazobactam 3 g (ceftolozane 2 g/tazobactam 1 g) every 8 hours while receiving continuous venovenous hemodiafiltration (CVVHDF). After the fifth dose of ceftolozane/tazobactam, plasma samples were obtained at 1-, 2-, 4-, 6-, and 8-hour time points. Two additional post-hemodialysis filter plasma samples were obtained to assess CVVHDF clearance. The maximum and minimum plasma concentrations for ceftolozane were 163.9 μg/ml and 79.4 μg/ml, respectively. The area under the plasma concentration-time curve from 0-8 hours (AUC0-8 ) was 689 μg hour/ml; the plasma half-life was 13.3 hours. The ceftolozane CVVHDF clearance and total clearance were 2.4 L/hour and 2.9 L/hour, respectively. Compared with a patient with normal renal function, this patient receiving CVVHDF had decreased ceftolozane clearance. A ceftolozane/tazobactam dosage of 1.5 g every 8 hours should adequately achieve a desired drug concentration above the minimum inhibitory concentration of 8 μg/ml for the treatment of pneumonia. Additional pharmacokinetic data are needed to confirm our results and for alternative forms of CRRT. © 2016 Pharmacotherapy Publications, Inc.

    To avoid complications of high dose corticosteroid, pemphigus patients are usually co-treated with other immunosuppressive agents. Liver enzyme abnormality occurs commonly during treatment and occasionally causes discontinuation of drugs. To assess the rate of therapy-induced hepatotoxicity in patients with immunobullous diseases, we conducted a study of 250 pemphigus patients under immunosuppressive therapy prospectively. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) plasma levels were recorded before the start of treatment and every week under treatment (up to 3 weeks). Hepatotoxicity was defined as the rise in the ALT plasma levels to greater than twice the upper normal limit. Approximately 81% of patients received prednisolone and azathioprine. Approximately 12% received only prednisolone. Hepatotoxicity occurred in 2.9% (n = 8) of patients after 1 week, in 7.8% (n = 20) after 2 weeks and in 11.5% (n = 29) after 3 weeks. No patient had jaundice or other clinical manifestations of hepatitis. The mean values of ALT and AST before the start of treatment were 20.7 ± 13.7 and 17.6 ± 10.8 U/L, respectively that grew to 47.5 ± 28.5 and 26.8 ± 14.5 U/L, 3 weeks after the initiation of treatment. Distribution of changes was not significantly different among groups of age, sex, immunosuppressive drugs and isoniazid consumption. Under usual treatment of pemphigus, hepatotoxicity occurs in 10% of patients during the first 3 weeks of therapy that does not seem to be associated with azathioprine or mycophenolate mofetil exclusively. High doses of prednisolone may play a role.

    Children with idiopathic apraxia experience difficulties planning the movements necessary for intelligible speech. There is increasing evidence that targeted early interventions, such as Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT), can be effective in treating these disorders. In this study, we investigate possible cortical thickness correlates of idiopathic apraxia of speech in childhood, and changes associated with participation in an 8-week block of PROMPT therapy. We found that children with idiopathic apraxia (n = 11), aged 3-6 years, had significantly thicker left supramarginal gyri than a group of typically-developing age-matched controls (n = 11), t(20) = 2.84, p ≤ 0.05. Over the course of therapy, the children with apraxia (n = 9) experienced significant thinning of the left posterior superior temporal gyrus (canonical Wernicke's area), t(8) = 2.42, p ≤ 0.05. This is the first study to demonstrate experience-dependent structural plasticity in children receiving therapy for speech sound disorders.

    Autologous stem cell transplant (ASCT) is an effective treatment for multiple myeloma (MM). However the timing of ASCT in the era of novel agents (lenalidomide, thalidomide, bortezomib) is unknown. We retrospectively reviewed the outcome of MM patients who received novel agent based induction treatment and received first ASCT within 12 months of diagnosis (early ASCT, N = 102), or at a later date (late ASCT, N = 65). Median time to ASCT was 7.9 months vs. 17.7 months in the early vs. late ASCT. The 3 and 5 yr overall Survival (OS) from diagnosis was 90 and 63% versus 82 and 63% in early and late ASCT respectively (P=0.45). Forty-one and 36 patients in the early and late ASCT have relapsed or progressed with median time to relapse of 28 and 23 mos (p=0.055). On multivariable analysis, factors predictive of increased risk for progression were ISS stage III (p=0.007), and < VGPR post-ASCT (p<0.001). Factor predictive of worst outcomes for OS was being on hemodialysis (p=0.037). No superiority of one agent was seen. In summary, early or late ASCT is a viable option for MM patients receiving induction treatment with novel targeted therapies. PMID:23194056

    Maintaining linear growth and weight gain in HIV-infected children is often difficult. Nutritional evaluation and support are recognised as important factors to improve their quality of life. Combination antiretroviral therapy including protease inhibitors (HAART) reduces HIV-viral load and improves survival, quality of life and nutritional status. Our study aimed to determine changes in nutrional status based on body weight, height and nutritional habits, of HIV-infected children receiving HAART. Possible side effects of lipid metabolism were also studied. Twenty five children, 13 treated with HAART (group B) were followed up for 12 months. We did not observe statistically significant differences in nutritional status over that time or between groups A and B. Inadequate energy intake was more common in patients with advanced HIV-disease. Hyperlipidemia was found in 70% of children receiving ritonavir and in approximately 50% of children receiving nelfinavir. We observed an important although not statistically significative modification in the height of those in group B.

    Objective The aim of this randomized controlled trial for patients with advanced cancer receiving radiation therapy was to determine the effect of a multidisciplinary intervention on spiritual quality of life (QOL) at the end of the intervention (week 4) and at two follow-up time points (weeks 26 and 52). Methods One hundred thirty-one persons were randomized to either the intervention or control (forms only) groups. The intervention included six 90-min in-person sessions based on the physical, emotion, social, and spiritual domains of QOL. Three sessions included the spiritual component. Caregivers were present for four sessions, one which included a spiritual component. Ten follow-up phone calls were made to the patients in the intervention group during the 6-month follow-up period. Patients completed the Functional Assessment of Cancer Therapy: General Scale, the Linear Analog Self-Assessment which includes an assessment of spiritual QOL, and the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-Sp) at enrollment, and weeks 4, 27, and 52. Results Following the intervention, the intervention group demonstrated improved spiritual QOL on the FACIT-Sp, whereas the spiritual QOL of the control group decreased, resulting in significant mean changes between groups (total score: 1.7 vs. −2.9; p <0.01; meaning/peace subscale: 1.0 vs. −3.5; p <0.01; faith subscale: 3.1 vs. −1.7; p = 0.04). Conclusions The results indicate that a multidisciplinary intervention which includes a spiritual component can maintain the spiritual QOL of patients with advanced cancer during radiation therapy.

    Through a multidisciplinary decision-making process, we developed a strategy of systemic therapy followed by local consolidative therapy (chemoradiation with/without surgery) in selected patients with metastatic gastroesophageal carcinoma (mGEAC). Only after a consensus during multidisciplinary discussions, local therapy was initiated. We identified 101 patients with mGEAC who had local consolidation. We evaluated the association between various clinical variables (location of the primary, location of metastases, duration of initial chemotherapy, histologic grade, and radiation dose) and overall survival (OS). Of 101 patients, 71 had a proximal primary (esophageal, Siewert type I or II), and 30 patients had a distal primary (Siewert type III or distal). The median OS was 25.7 months (95% confidence interval [CI] 22.3-32.8). The OS rates at 2 and 5 years were 53.8% (95% CI 44.7-64.8) and 20.7% (95% CI 13.4-31.9), respectively. OS was highly associated with the location of the primary (median of 22.8 months for Siewert I/II vs. 41.5 months for Siewert III or distal, p = 0.03). The duration of initial chemotherapy was highly associated with OS (median of 21.8 months for <3 months vs. 32.5 months for ≥3 months, p = 0.004). Some mGEAC patients with a favorable clinical course can achieve a ∼20% 5-year survival rate with an approach that uses initial chemotherapy followed by multidisciplinary discussion to proceed with consolidation with local therapy. Patients with distal GEAC and those who receive initial chemotherapy for ≥3 months are the maximum beneficiaries. © 2017 S. Karger AG, Basel.

    Extramedullary hematopoiesis (EMH) develops as a compensatory mechanism associated with hematologic processes but it may occur in association with chemotherapy. Three cases of EMH arising in axillary lymph nodes following neoadjuvant therapy for breast carcinoma are reported herein. Three women ranging in age from 41 to 47 years presented with unilateral breast masses measuring 0.6 to 4.0 cm in greatest dimension and were diagnosed with infiltrating ductal carcinoma, grade III by core needle biopsies. Two of the tumors were triple negative and one was estrogen receptor positive. All patients subsequently received neoadjuvant therapy followed by lumpectomies. No residual carcinoma was identified in postchemotherapy breast resection specimens. One patient underwent a sentinel lymph node procedure, the second patient an axillary lymph node dissection, and the third patient had a core biopsy of an enlarged axillary lymph node. The patient that underwent axillary lymph node dissection had metastatic carcinoma in one of her lymph nodes. Foci of EMH consisting of myeloid, erythroid, and megakaryocytic precursors were present within the nodal parenchyma and/or subcapsular sinuses of axillary lymph nodes of all three cases. Megakaryocytes were immunoreactive with factor VIII, erythroid elements with Glycophorin and myeloid precursors with myeloperoxidase. With increasing use of neoadjuvant therapy for breast carcinoma, EMH within lymph nodes is more likely to be encountered. Hematopoietic precursors present in lymph nodes may potentially be misdiagnosed as metastatic tumor cells, particularly as lobular carcinoma or metaplastic carcinoma. Therefore, caution should be exercised when evaluating axillary lymph nodes in the clinical setting of neoadjuvant therapy for breast carcinoma.

    Sitafloxacin (STFX) is a newly developed quinolone that has robust antimicrobial activity against periodontopathic bacteria. We previously reported that oral administration of STFX during supportive periodontal therapy was as effective as conventional mechanical debridement under local anesthesia microbiologically and clinically for 3 months. The aim of the present study was to examine the short-term and long-term microbiological and clinical effects of systemic STFX and azithromycin (AZM) on active periodontal pockets during supportive periodontal therapy. Fifty-one patients receiving supportive periodontal therapy were randomly allocated to the STFX group (200 mg/day of STFX for 5 days) or the AZM group (500 mg/day of AZM for 3 days). The microbiological and clinical parameters were examined until 12 months after the systemic administration of each drug. The concentration of each drug in periodontal pockets and the antimicrobial susceptibility of clinical isolates were also analyzed. The proportions of red complex bacteria, i.e., Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, which are the representative periodontopathic bacteria, were significantly reduced at 1 month and remained lower at 12 months than those at baseline in both the STFX and AZM groups. Clinical parameters were significantly improved over the 12-month period in both groups. An increase in the MIC of AZM against clinical isolates was observed in the AZM group. These results indicate that monotherapy with systemic STFX and AZM might be an alternative treatment during supportive periodontal therapy in patients for whom invasive mechanical treatment is inappropriate.

    The effect of pilocarpine hydrochloride on the anterior chamber depth and lens thickness was measured in 20 eyes of patients with chronic open-angle glucoma who were receiving long-term glaucoma therapy with pilocarpine. Measurements were made with high-resolution ultrasonic biometry. This study demonstrated that regardless of their age (58.4 years, average) and the fact that they had been regularly using pilocarpine from two to four times a day, 85% of these patients demonstrated narrowing of the anterior chamber (AC) depth (average, 0.19 mm) and thickening of the lens (average, 0.21 mm) with each instillation of pilocarpine. In approximately 15% of eyes, a repeatable deepening of the AC depth and flattening of the lens was noted.

    Healthy lifestyle behaviors could have a role in ameliorating some of the adverse effects of androgen suppression therapy (AST) in men with prostate cancer. The primary aim of this study was to assess the feasibility of a tapered supervised exercise program in combination with dietary advice in men with advanced prostate cancer receiving AST. Advanced prostate cancer patients receiving AST for a minimum of 6 months were randomized to a 12-week lifestyle program comprising aerobic and resistance exercise, plus dietary advice (n = 25), or standard care (n = 25). Exercise behavior, dietary macronutrient intake, quality of life, fatigue, functional fitness, and biomarkers associated with disease progression were assessed at baseline, after the intervention, and at 6 months. The lifestyle group showed improvements in exercise behavior (P < 0.001), dietary fat intake (P = 0.001), total energy intake (P = 0.005), fatigue (P = 0.002), aerobic exercise tolerance (P < 0.001), and muscle strength (P = 0.033) compared with standard care controls. Although a high rate of attrition (44%) was observed at 6 months, the improvements in key health outcomes were sustained. No effects on clinical prostate cancer disease markers were observed. This preliminary evidence suggests that pragmatic lifestyle interventions have potential to evoke improvements in exercise and dietary behavior, in addition to other important health outcomes in men with advanced prostate cancer receiving AST. This study shows for the first time that pragmatic lifestyle interventions are feasible and could have a positive impact on health behaviors and other key outcomes in men with advanced prostate cancer receiving AST.

    Background While electroconvulsive therapy (ECT) has been used for many years, there is insufficient research regarding the indications for continuation/maintenance (C/M)-ECT, its safety and efficacy, and the characteristics of patients with schizophrenia or schizoaffective disorder who receive multiple ECT sessions. The aims of this study were to characterize a series of patients who received 30 ECT sessions or more, to describe treatment regimens in actual practice, and to examine the results of C/M-ECT in terms of safety and efficacy, especially the effect on aggression and functioning. Methods We performed a retrospective chart review of 20 consecutive patients (mean age 64.6 years) with schizophrenia (n=16) or schizoaffective disorder (n=4) who received at least 30 ECT sessions at our ECT unit, and also interviewed the treating physician and filled out the Clinical Global Impression-Severity, Global Assessment of Functioning, and the Staff Observation Aggression Scale-Revised. Results Patients received a mean of 91.3 ECT sessions at a mean interval of 2.6 weeks. All had been hospitalized for most or all of the previous 3 years. There were no major adverse effects, and cognitive side effects were relatively minimal (cognitive deficit present for several hours after treatment). We found that ECT significantly reduced scores on the Staff Observation Aggression Scale-Revised subscales for verbal aggression and self-harm, and improved Global Assessment of Functioning scores. There were reductions in total aggression scores, subscale scores for harm to objects and to others, and Clinical Global Impression-Severity scores, these were not statistically significant. Conclusion C/M-ECT is safe and effective for chronically hospitalized patients. It improves general functioning and reduces verbal aggression and self-harm. More research using other aggression tools is needed to determine its effects and to reproduce our findings in prospective and controlled studies. PMID

    A higher prevalence of QT prolongation has been reported among human immunodeficiency virus (HIV)-infected patients. Previous studies have demonstrated that QT dispersion is a better predictor of serious ventricular tachyarrhythmia and cardiac mortality than corrected QT (QTc) interval. However, data of QT dispersion in HIV-infected patients receiving a combined antiretroviral therapy (cART) is limited. We sought to assess QTc interval and QT dispersion in HIV-infected patients receiving cART. The association between QT parameters and heart rate variability (HRV) was also examined. Ninety-one HIV-infected patients receiving cART (male = 33, mean age = 44 ± 10 years) and 70 HIV-seronegative subjects (male = 25, mean age = 44 ± 8 years) were enrolled in the study. In a resting 12-lead electrocardiogram, QT interval was measured by the tangent method in all leads with well-defined T waves. The QT dispersion was defined as the difference between maximum and minimum QTc intervals in any of 12 leads. The baseline characteristics were not different between the two groups. We demonstrated the significantly longer mean QTc interval (420 ± 21 vs. 409 ± 21 ms, P < 0.001), and greater QT dispersion in HIV-infected group compared to the control group (85 ± 29 vs. 55 ± 23 ms, P < 0.001). Among the HIV-infected patients, those who had lower CD4 lymphocyte count (<350 cells/mm(3)) tended to have greater QT dispersion (92 ± 28 vs. 81 ± 29 ms, P = 0.098). There were no associations between QT parameters and either HRV or cART regimens. HIV-infected patients receiving cART were associated with prolonged QTc interval and increased QT dispersion, independent of autonomic dysfunction and antiretroviral drugs, which may have led to the potentially higher risk of ventricular arrhythmia and cardiac mortality. © 2014 Wiley Periodicals, Inc.

    Purpose Long-term oxygen therapy (LTOT) is one of the main treatments for patients with chronic obstructive pulmonary disease. Patients receiving LTOT may have less than optimal home conditions and this may interfere with treatment. The objective of this study was, through home visits, to identify the characteristics of patients receiving LTOT and to develop knowledge regarding the home environments of these patients. Methods Ninety-seven patients with a mean age of 69 plus or minus 10.5 years were evaluated. This study was a cross-sectional descriptive analysis. Data were collected during an initial home visit, using a questionnaire standardized for the study. The results were analyzed retrospectively. Results Seventy-five percent of the patients had chronic obstructive pulmonary disease, and 11% were active smokers. The patients’ mean pulse oximetry values were 85.9% plus or minus 4.7% on room air and 92% plus or minus 3.9% on the prescribed flow of oxygen. Most of the patients did not use the treatment as prescribed and most used a humidifier. The extension hose had a mean length of 5 plus or minus 3.9 m (range, 1.5–16 m). In the year prior to the visit, 26% of the patients received emergency medical care because of respiratory problems. Few patients reported engaging in leisure activities. Conclusion The home visit allowed us to identify problems and interventions that could improve the way LTOT is used. The most common interventions related to smoking cessation, concentrator maintenance and cleaning, use of a humidifier, and adjustments of the length of the connector hose. Therefore, the home visit is a very important tool in providing comprehensive care to patients receiving LTOT, especially those who show lack of adequate progress and those who show uncertainty about the treatment method.

    Purpose Photon therapy has been reported to induce resets of implanted cardiac devices, but the clinical sequelae of treating patients with such devices with proton beam therapy (PBT) are not well known. We reviewed the incidence of device malfunctions among patients undergoing PBT. Methods From March 2009 through July 2012, 42 patients with implanted cardiac implantable electronic devices (CIEDs) (28 pacemakers and 14 cardioverter-defillibrators) underwent 42 courses of PBT for thoracic (23 [55%]), prostate (15 [36%]), liver (3[7%]), or base of skull (1 [2%]) tumors at a single institution. The median prescribed dose was 74 Gy(RBE) [range 46.8–87.5 Gy(RBE)], and the median distance from the treatment field to the CIED was 10 cm (range 0.8–40 cm). Maximum proton and neutron doses were estimated for each treatment course. All CIEDs were checked before radiation delivery and monitored throughout treatment. Results Median estimated peak proton and neutron doses to the CIED in all patients were 0.8 Gy (range 0.13–21 Gy) and 346 Sv (range 11–1100 mSv). Six CIED malfunctions occurred in five patients (2 pacemakers and 3 defibrillators). Five of these malfunctions were CIED resets, and one patient with a defibrillator (in a patient with a liver tumor) had an elective replacement indicator (ERI) after therapy that was not influenced by radiation. The mean distance from the proton beam to the CIED among devices that reset was 7.0 cm (range 0.9–8 cm), and the mean maximum neutron dose was 655 mSv (range 330–1100 mSv). All resets occurred in patients receiving thoracic PBT and were corrected without clinical incident. The generator for the defibrillator with the ERI message was replaced uneventfully after treatment. Conclusions The incidence of CIED resets was about 20% among patients receiving PBT to the thorax. We recommend that PBT be avoided in pacing-dependent patients and that patients with any type of CIED receiving thoracic PBT be followed closely. PMID

Methods and Materials: From March 2009 through July 2012, 42 patients with implanted cardiac implantable electronic devices (CIED; 28 pacemakers and 14 cardioverter-defibrillators) underwent 42 courses of PBT for thoracic (23, 55%), prostate (15, 36%), liver (3, 7%), or base of skull (1, 2%) tumors at a single institution. The median prescribed dose was 74 Gy (relative biological effectiveness; range 46.8-87.5 Gy), and the median distance from the treatment field to the CIED was 10 cm (range 0.8-40 cm). Maximum proton and neutron doses were estimated for each treatment course. All CIEDs were checked before radiation delivery and monitored throughout treatment.

    In patients with established cardiovascular disease, residual cardiovascular risk persists despite the achievement of target low-density lipoprotein (LDL) cholesterol levels with statin therapy. It is unclear whether extended-release niacin added to simvastatin to raise low levels of high-density lipoprotein (HDL) cholesterol is superior to simvastatin alone in reducing such residual risk. We randomly assigned eligible patients to receive extended-release niacin, 1500 to 2000 mg per day, or matching placebo. All patients received simvastatin, 40 to 80 mg per day, plus ezetimibe, 10 mg per day, if needed, to maintain an LDL cholesterol level of 40 to 80 mg per deciliter (1.03 to 2.07 mmol per liter). The primary end point was the first event of the composite of death from coronary heart disease, nonfatal myocardial infarction, ischemic stroke, hospitalization for an acute coronary syndrome, or symptom-driven coronary or cerebral revascularization. A total of 3414 patients were randomly assigned to receive niacin (1718) or placebo (1696). The trial was stopped after a mean follow-up period of 3 years owing to a lack of efficacy. At 2 years, niacin therapy had significantly increased the median HDL cholesterol level from 35 mg per deciliter (0.91 mmol per liter) to 42 mg per deciliter (1.08 mmol per liter), lowered the triglyceride level from 164 mg per deciliter (1.85 mmol per liter) to 122 mg per deciliter (1.38 mmol per liter), and lowered the LDL cholesterol level from 74 mg per deciliter (1.91 mmol per liter) to 62 mg per deciliter (1.60 mmol per liter). The primary end point occurred in 282 patients in the niacin group (16.4%) and in 274 patients in the placebo group (16.2%) (hazard ratio, 1.02; 95% confidence interval, 0.87 to 1.21; P=0.79 by the log-rank test). Among patients with atherosclerotic cardiovascular disease and LDL cholesterol levels of less than 70 mg per deciliter (1.81 mmol per liter), there was no incremental clinical benefit from the addition

    Tacrolimus is a potent immunosuppressive agent and has been used in liver transplantation (LTx) for nearly a decade. More than 70% of children can be maintained on tacrolimus monotherapy, without steroids, by the end of 1 yr post-Tx. This freedom from steroids does not appear to change significantly in subsequent years. The use of steroids has obvious metabolic and cosmetic disadvantages, besides affecting linear growth in children. The present study identifies why some children still require steroid therapy after successful LTx. One hundred and sixty-six consecutive pediatric patients who had undergone primary LTx between October 1989 and December 1992, were included in this study. Follow-up ranged from 6 to 9 yr (mean 7.5 +/- 0.8 yr). One hundred and forty-one children were alive in November 1998 and these patients constituted the study group. Their current rate of prednisone use, reason for prednisone use, and prednisone dose were examined retrospectively. Of the 141 patients, 139 (98.5%) had stopped taking steroids at some time-point after LTx. Thirteen patients (9%) were off immunosuppression altogether (group I), 97 were undergoing tacrolimus monotherapy (group II), and the remaining 31 were receiving therapy with steroids and tacrolimus (group III). The mean prednisone dose at the last follow-up was 6.5 +/- 4.9 mg/day (median 5.0 mg/day). In group III, two children were never weaned off steroids because of inadequate follow-up (both lived outside the country), and the remaining 29 children completely stopped steroid therapy at some time-point after LTx; however, prednisone was re-introduced for clinically suspected or biopsy-proven rejection in 24. Seven children in group III had completely stopped immunosuppressive therapy either as part of an immunosuppression reduction protocol (n = 3) or for suspected or proven post-transplant lymphoproliferative disorder (PTLD) (n = 4). In eleven of the 18 children in group III, requirement of steroid for rejection was

    Antipsychotic polypharmacy (APP) is frequent, but its pattern is unknown in treatment-refractory schizophrenia-spectrum patients receiving electroconvulsive therapy (ECT). We performed a retrospective chart review of ECT-treated inpatients hospitalized at 2 Danish University hospitals from 2003 to 2008, focusing on APP patterns in patients with schizophrenia-spectrum disorders (n = 79, 13.2%). In addition to univariate analyses, a multivariate logistic regression analysis was performed to identify independent predictors of APP. Of 79 antipsychotic-treated patients (aged 48.6 ± 14.2 years; illness duration, 18.3 ± 10.6 years) ultimately treated with ECT, 86.1% received 2 or more psychotropic medications, including mood stabilizers (19.0%), antidepressants (32.9%), and APP (72.2%; 2 antipsychotics = 41.8%, 3 = 21.5%, 4-5 = 7.6%). Most patients received first-generation antipsychotic (FGA) + second-generation antipsychotic (SGA) (48.1%), followed by SGA + SGA (24.1%), SGA monotherapy (22.8%), and FGA monotherapy (5.1%). Individual antipsychotics included olanzapine (44.3%), risperidone (26.6%), clozapine (26.6%), quetiapine (22.1%), ziprasidone (13.9%), aripiprazole (10.1%), and sertindole (3.8%). Antipsychotic polypharmacy was associated with a greater number of FGAs (0.8 ± 0.7 vs 0.1 ± 0.4, P < 0.0001) and SGAs (1.7 ± 0.8 vs 0.8 ± 0.4, P < 0.0001), zuclopenthixol use (31.6% vs 0%, P = 0.0019), olanzapine use (52.6% vs 22.7%, P = 0.017), less serotonin-noradrenaline reuptake inhibitor use (3.5% vs 18.2%, P = 0.027), and a trend toward more good to excellent ECT response (86.0% vs 68.2%, P = 0.071). In the logistic regression analysis, APP was independently associated with a higher number of FGAs (P = 0.0002) and olanzapine use (P = 0.0098) (r = 0.314, P < 0.0001). Only 22.6% of this treatment-refractory population received clozapine, yet 72.4% received APP. Following the results from our study as well as the general level of evidence, patients with refractory

    The literature on the pharmacokinetics of vancomycin in patients undergoing extracorporeal membrane oxygenation (ECMO) therapy is sparse. A population pharmacokinetic (PK) model for vancomycin in ECMO patients was developed using a nonlinear mixed effects modeling on the concentration–time profiles of 14 ECMO patients who received intravenous vancomycin. Model selection was based on log‐likelihood criterion, goodness of fit plots, and scientific plausibility. Identification of covariates was done using a full covariate model approach. The pharmacokinetics of vancomycin was adequately described with a two‐compartment model. Parameters included clearance of 2.83 L/hr, limited central volume of distribution 24.2 L, and low residual variability 0.67%. Findings from the analysis suggest that standard dosing recommendations for vancomycin in non‐ECMO patients are adequate to achieve therapeutic trough concentrations in ECMO patients. This further shows that ECMO minimally affects the PK of vancomycin in adults including in higher‐weight patients. PMID:27639260

    The aim of the study was medico-social characteristic of HIV-infected patients receiving antiretroviral therapy in 2006-2012 based on the logical and comparative analysis of medical cards with the use of systemic informational approach. The study yielded the medico-social characteristic of HIV-infected patients suggesting the presence of concomitant disorders requiring prescription of several medications to be used either simultaneously or alternatively (in case of poor efficiency or side effects of primary treatment). The data obtained indicate the necessity of optimization of the choice and prescription of pharmacotherapy taking account of its effects and safety based on the analysis of the potential and cost-effectiveness of different therapeutic modalities. The results of the study can be used to develop organizational measures for the improvement of public drug supply.

    Medication adherence remains a critical link between the prescribed ART regimen and treatment outcome. Several factors may influence adherence behavior. This cross-sectional study aimed to highlight socioeconomic predictors of adherence behavior among a cohort of 242 adult Malaysian patients receiving antiretroviral therapy in Hospital Sungai Buloh, Malaysia, where they were enrolled in a parent study (single-blinded randomized controlled trial) between January and December 2014. Statistical analysis of secondary data on adherence behavior and sociodemographic characteristics of the patients revealed mean age of 33.4 years and ranged from 18 to 64 years; 88.8% were males. A total of 224 (93%) patients who completed 6 months' adherence assessment were included in the model. Of these, 135 (60.3%) achieved optimal adherence. Multivariate binary logistic regression analysis revealed that patient's income and ethnicity were significant predictors of adherence behavior. This may be valuable for targeted programmatic interventions to further enhance successful treatment outcomes among the target population.

    Background: Although electroconvulsive therapy (ECT) is used quite frequently among the bipolar patients in developing countries, very little data are available with regard to its effectiveness from the developing countries. Aim: A retrospective case note review was carried out of bipolar disorder patients who were given ECT. Materials and Methods: Details of demographic and clinical profile, indications for ECT, response patterns, adverse effects, etc. were recorded. Results: Among all the patients who received ECT, 18% were diagnosed to have bipolar disorder. ECT was administered most commonly for mania with psychotic symptoms, followed by severe depression with psychotic symptoms. Comorbid physical problems were seen in many patients. Nearly 90% of patients in both the subgroups showed more than 50% response (based on reduction in the standardized rating scales) with ECT. Few patients (22%) reported some kind of side effects. Conclusions: ECT is useful in the management of acute phase of mania and depression. PMID:22556436

    Vancomycin is frequently administered as a continuous infusion to treat severe infections caused by Gram-positive bacteria. Previous studies have suggested a loading dose of 15 mg/kg followed by continuous infusion of 30 mg/kg in patients with normal renal function; however, there are no dosing recommendations in patients with renal failure undergoing continuous renal replacement therapy (CRRT). Data from all adult septic patients admitted to a Department of Intensive Care over a 3-year period in whom vancomycin was given as a continuous infusion were reviewed. Patients were included if they received vancomycin for ≥48h during CRRT. Vancomycin levels were obtained daily. During the study period, 85 patients (56 male; mean age 65±15 years; weight 85±24kg) met the inclusion criteria. Median (interquartile range) APACHE II and SOFA scores were 24 (20-29) and 11 (7-14), respectively, and the overall mortality rate was 59%. Mean vancomycin doses were 16.4±6.4 (loading dose), 23.5±8.1 (Day 1), 23.2±7.4 (Day 2) and 23.3±11.0 (Day 3) mg/kg, resulting in blood concentrations of 24.7±9.0 (Day 1), 26.0±8.1 (Day 2) and 27.7±9.3 (Day 3) μg/mL. On Day 1, 43 patients (51%) had adequate drug concentrations (20-30 μg/mL), 17 (20%) had levels >30 μg/mL and 25 (29%) had levels <20 μg/mL. Most patients with adequate drug concentrations received a daily dose of 16-35 mg/kg. The intensity of CRRT directly influenced vancomycin concentrations on Day 1 of therapy.

    Continuous renal replacement therapy (CRRT) is the preferred renal replacement therapy modality in the critically ill. We aimed to reveal the literature on the pharmacokinetic studies in critically ill patients receiving CRRT with special reference to quality assessment of these studies and the CRRT dose. We conducted a systematic review by searching the MEDLINE, EMBASE, and the Cochrane databases to December 2009 and bibliographies of relevant review articles. We included original studies reporting from critically ill adult subjects receiving CRRT because of acute kidney injury with a special emphasis on drug pharmacokinetics. We used the minimum reporting criteria for CRRT studies by Acute Dialysis Quality Initiative (ADQI) and, second, the Downs and Black checklist to assess the quality of the studies. We calculated the CRRT dose per study. We included pharmacokinetic parameters, residual renal function, and recommendations on drug dosing. Of 182 publications, 95 were considered relevant and 49 met the inclusion criteria. The median [interquartile range (IQR)] number of reported criteria by ADQI was 7.0 (5.0-8.0) of 12. The median (IQR) Downs and Black quality score was 15 (14-16) of 32. None of the publications reported CRRT dose directly. The median (IQR) weighted CRRT dose was 23.7 (18.8-27.9) ml/kg/h. More attention should be paid both to standardizing the CRRT dose and reporting of the CRRT parameters in pharmacokinetic studies. The general quality of the studies during CRRT in the critically ill was only moderate and would be greatly improved by reports in concordant with the ADQI recommendations. © 2011 The Authors Acta Anaesthesiologica Scandinavica © 2011 The Acta Anaesthesiologica Scandinavica Foundation.

    The aim of the present study was to determine the risk of myopathy in older people receiving statin therapy. Eligible studies were identified searching Ovid Medline, EMBASE, Scopus, CINAHL, Cochrane and PSYCHINFO databases (1987 to July 2014). The selection criteria comprised randomized controlled studies that compared the effects of statin monotherapy and placebo on muscle adverse events in the older adult (65+ years). Data were extracted and assessed for validity by the authors. Odds ratios and 95% confidence intervals (CIs) were used to calculate binary outcomes. Evidence from included studies were pooled in a meta-analysis using Revman 5.3. The trials assessed in the systematic review showed little or no evidence of a difference in risks between treatment and placebo groups, with myalgia [odds ratio (OR) 1.03, 95% CI 0.90, 1.17; I(2) = 0%; P = 0.66] and combined muscle adverse events (OR 1.03, 95% CI 0.91, 1.18; I(2) = 0%; P = 0.61) (myopathy). No evidence was found for an increased risk of rhabdomyolysis (OR 2.93, 95% CI 0.30, 28.18; I(2) = 0%; P = 0.35) in the seven trials that reported this. No trials reported mortality due to a muscle-related event. Discontinuations due to an adverse effect were reduced in the treatment group compared with placebo (OR 0.74, 95% CI 0.50, 1.09; I(2) = 0%; P = 0.13). The results obtained from the present review suggest that statins are relatively safe, even in older people. There was no evidence to suggest an increased risk of myopathy in older adults receiving statin therapy. There is slightly increased seen with rhabdomyolysis when compared with the general population, although the event is relatively rare. Statins should be prescribed to elderly people who need it, and not withheld, as its myopathy safety profile is tolerable. © 2015 The British Pharmacological Society.

  9. Cardiovascular Disease Among Transgender Adults Receiving Hormone Therapy: A Narrative Review.

    Recent reports estimate that 0.6% of adults in the United States, or approximately 1.4 million persons, identify as transgender. Despite gains in rights and media attention, the reality is that transgender persons experience health disparities, and a dearth of research and evidence-based guidelines remains regarding their specific health needs. The lack of research to characterize cardiovascular disease (CVD) and CVD risk factors in transgender populations receiving cross-sex hormone therapy (CSHT) limits appropriate primary and specialty care. As with hormone therapy in cisgender persons (that is, those whose sex assigned at birth aligns with their gender identity), existing research in transgender populations suggests that CVD risk factors are altered by CSHT. Currently, systemic hormone replacement for cisgender adults requires a nuanced discussion based on baseline risk factors and age of administration of exogenous hormones because of concern regarding an increased risk for myocardial infarction and stroke. For transgender adults, CSHT has been associated with the potential for worsening CVD risk factors (such as blood pressure elevation, insulin resistance, and lipid derangements), although these changes have not been associated with increases in morbidity or mortality in transgender men receiving CSHT. For transgender women, CSHT has known thromboembolic risk, and lower-dose transdermal estrogen formulations are preferred over high-dose oral formulations. In addition, many studies of transgender adults focus predominantly on younger persons, limiting the generalizability of CSHT in older transgender adults. The lack of randomized controlled trials comparing various routes and formulations of CSHT, as well as the paucity of prospective cohort studies, limits knowledge of any associations between CSHT and CVD.

    To assess ankle function 4 weeks after conservative management and to examine the correlation of function with gait. A prospective comparison study. Thirty patients with grade I or II acute ankle sprains were followed up after 4 weeks of conservative management not involving physical therapy. Participants underwent a clinical assessment and had to walk at a normal self-selected walking speed. Their results were compared with the data of 15 healthy subjects. Participants' joint swelling, muscle strength, passive mobility, and pain were assessed. In addition, patients' temporal-spatial, kinematic, and kinetic gait data were measured while walking. Muscle strength and passive mobility were significantly reduced on the injured side compared with the noninjured side (P < .001). During gait analysis, patients with ankle sprains showed slower walking speed, shorter step length, shorter single support time, reduced and delayed maximum plantar flexion, decreased maximum power, and decreased maximum moment (P < .050) compared with healthy persons. Decreased walking speed was mainly correlated with pain (R = -0.566, P = .001) and deficits in muscle strength of dorsiflexors (R = 0.506, P = .004). Four weeks after an ankle sprain, patients who did not receive physical therapy showed physical impairments of the ankle that were correlated with gait parameters. These findings might help fine-tune rehabilitation protocols. Copyright © 2015 American Academy of Physical Medicine and Rehabilitation. Published by Elsevier Inc. All rights reserved.

    Background Increasing numbers of patients with breast cancer are being treated with postmastectomy radiation therapy (PMRT). The author reviewed the literature to determine the clinical impact of this increasing use of PMRT in patients with breast cancer who desire implant-based breast reconstruction. Methods The author searched the MEDLINE database for articles on breast reconstruction and radiation therapy published between January 2008 and June 2011, and reviewed the abstracts of those articles to identify articles with information about the impact of radiation on implant-based breast reconstruction. This subgroup of articles was reviewed in detail. Results Two-hundred eighty-five articles were identified. 19 papers were reviewed in detail. 8 papers provided level III evidence; one provided level I or II (n = 8) evidence from high-quality multicenter or single-center randomized controlled trials or prospective cohort studies. Two papers provided level IV evidence from case series and were included in the review because they offered a novel approach or perspective. The most recent studies find a significant need for unplanned or major corrective surgery in irradiated breasts reconstructed with implants. Although breast implant reconstruction in irradiated breasts is associated with high rates of complications; only a minority of patients require conversion to an autologous tissue flap. Conclusions Although the majority of patients who undergo implant-based reconstruction and receive radiation ultimately keep the implant reconstruction, patient surveys show that radiation has a significantly negative effect on patient satisfaction.

    To examine whether concomitant statin therapy affects glycemic control with saxagliptin 2.5 and 5mg/d in patients with type 2 diabetes mellitus (T2DM). Efficacy and safety were analyzed post hoc for pooled data from 9 saxagliptin randomized, placebo-controlled trials with a primary 24-week treatment period (4 monotherapy, 2 add-on to metformin, 1 each add-on to a sulfonylurea, thiazolidinedione, or insulin±metformin). Safety was also assessed in an 11-study, 24-week pool and an extended 20-study pool, which included 9 additional 4- to 52-week randomized studies. Comparisons were performed for patient groups defined by baseline statin use. Saxagliptin produced greater mean reductions in glycated hemoglobin than placebo, with no interaction between treatment and baseline statin use (P=0.47). In patients receiving saxagliptin 2.5 and 5mg and placebo, the proportion of patients with ≥1 adverse event (AE) was 78.1%, 64.0%, and 63.2%, respectively, in patients with any statin use and 70.6%, 57.9%, and 55.0% in patients with no statin use. Serious AEs, deaths, and symptomatic confirmed hypoglycemia (fingerstick glucose ≤50mg/dL) were few and similar, irrespective of baseline statin use. Saxagliptin improves glycemic control and is generally well tolerated in patients with T2DM, irrespective of concomitant statin therapy. Copyright © 2014 Elsevier Inc. All rights reserved.

    Treprostinil is a prostacyclin analogue approved for the treatment of pulmonary arterial hypertension (PAH). It is commonly administered through a central venous catheter (CVC). Treprostinil is associated with the incidence of Gram-negative bacterial bloodstream infections (BSI), a susceptibility that has been associated with a diluent used for treprostinil. We report the case of a 14-year-old boy with idiopathic PAH on continuous intravenous treprostinil therapy who presented with fever and fatigue. A blood culture drawn from his CVC was positive for the rare Gram-negative organism Chryseomonas luteola. The patient made a complete recovery with antibacterial treatment. This is the only documented case of a C. luteola BSI in a PAH patient receiving continuous intravenous treprostinil. We recommend maintaining a high index of suspicion for both common and rare Gram-negative pathogens and the early administration of appropriate antibiotic therapy in this population. The use of an alternate diluent solution, such as Sterile Diluent for Flolan, further decreases the infection risk.

    Purpose To assess the caregiver burden and factors determining the burden in patients receiving ranibizumab therapy for neovascular AMD (nAMD). Methods This is a cross-sectional questionnaire survey of 250 matched patient caregiver dyads across three large ophthalmic treatment centres in United Kingdom. The primary outcome was the subjective caregiver burden measured using caregiver reaction assessment scale (CRA). Objective caregiver burden was determined by the caregiver tasks and level of care provided. The factors that may predict the caregiver burden such as the patient’s visual acuity of the better eye and vision related quality of life, demographics, satisfaction and support provided by the healthcare and the health status of the dyads were also collected and assessed in a hierarchical regression model. Results The mean CRA score was 3.2±0.5, similar to the score reported by caregivers for atrial fibrillation who require regular hospital appointments for monitoring their thromboprophylaxis. Caregiver tasks including accompanying for hospital appointments for eye treatment and patient’s visual acuity in the better eye were the biggest contributors to the caregiver burden hierarchical model explaining 18% and 11% of the variance respectively. Conclusion Ranibizumab therapy for nAMD is associated with significant caregiver burden. Both disease impact and treatment frequency contributed to the overall burden. PMID:26056840

    To study the effects of repeated intravitreal injection of anti-VEGF drug bevacizumab on the vitreoretinal interface (VRI). Patients undergoing intravitreal injection of bevacizumab were enrolled. Eyes with media haze, uveitis, high myopia, history of cataract surgery or laser capsulotomy in last 6 months and complicated pseudophakia were excluded. VRI evaluation was done monthly for a minimum of 6 months. The nature and timing of the change(s) event was recorded. A total of 100 eyes were evaluated. Thirty-seven eyes developed new vitreoretinal interface change event (VICE). Pseudophakia (OR = 5.23, 95% CI = 1.99-14.07, p = 0.001), pre-injection VRI abnormality (OR = 2.63, 95% CI = 1.13-6.14, p = 0.024) and older age at enrollment (62.6 ± 13.9 vs. 56.3 ± 14 years) were risk factors for development of VICE. Eighty percent of interface events occurred in the first 3 months of therapy. Eight needed surgical intervention for consequences of vitreoretinal separation. VICE is not infrequent in eyes receiving anti-VEGF therapy though rarely need surgical intervention. The first 3 months are the critical months to watch out for these events. The treating ophthalmologists must keep the risk factors for development of in mind and monitor and counsel patients accordingly.

    Glycopeptides have been considered the antimicrobials of choice for serious meticillin-resistant Staphylococcus aureus (MRSA) and meticillin-resistant coagulase-negative staphylococci (MR-CoNS) infections for several years. Daptomycin is a new option for the treatment of these infections, including those exhibiting reduced susceptibility to glycopeptides. The aim of this study was to compare glycopeptides and daptomycin for the treatment of infections caused by MRSA or MR-CoNS. Data for 106 patients with bloodstream infections (bacteraemia or infective endocarditis) or skin and soft-tissue infections (SSTIs) were retrospectively reviewed, of which 43 were treated with daptomycin (DAP group) and 63 were treated with vancomycin or teicoplanin (GLYCO group). Patients included in the two comparison groups were homogeneous in terms of age, risk factors and clinical severity. Aetiology was mainly represented by MRSA in both groups, followed by various species of MR-CoNS. Daptomycin was used more frequently in patients with central venous catheter-associated bacteraemia or pacemaker-associated infection. Patients with SSTIs included in the GLYCO group had a longer mean duration of antibiotic therapy (18.2 days vs. 14.6 days; P=0.009) and a longer mean length of hospital stay (28.2 days vs. 19.6 days; P=0.01) compared with those included in the DAP group. A longer mean duration of antibiotic therapy was also observed in patients with bloodstream infections receiving glycopeptide therapy (25.6 days vs. 18 days; P=0.004). In conclusion, the good clinical efficacy of daptomycin is associated with a more rapid resolution of the clinical syndrome and a reduced length of hospitalisation. This latter aspect may have important pharmacoeconomic implications, promoting the use of daptomycin in the clinical setting.

    We report a case of an inadvertent increase in the international normalized ratio (INR) after the addition of bismuth subsalicylate for the treatment of diarrhea in an enterally fed patient receiving warfarin therapy. A 56-year-old Caucasian female presented to the trauma intensive care unit (ICU) with multiple lower extremity fractures. Warfarin was initiated for deep vein thrombosis prophylaxis due to the patient's inability to ambulate. The target INR was 2-3. Continuous intragastric enteral feeding was withheld 1 hour before and 1 hour after intragastric administration of warfarin. Bismuth subsalicylate 30 mL every 4 hours was prescribed for diarrhea. Within 3 days after starting bismuth subsalicylate therapy, the patient's INR increased from 2.56 to 3.54 and minor bleeding was noted from the patient's tracheostomy site. No significant change in warfarin dosage, variability in vitamin K intake, or medications that potentially alter warfarin metabolism were present during the unexpected rise in INR. When the bismuth subsalicylate was discontinued, the patient's INR stabilized into the target range on the same warfarin dose given at the time of the supratherapeutic INR. Salicylate displaces warfarin from plasma protein binding sites and may result in a significant increase in INR secondary to redistribution of warfarin to the free active form. Evaluation of this case report using the Drug Interaction Probability Scale and Naranjo Adverse Drug Reaction Probability Scale yielded scores consistent with a probable adverse drug interaction. Bismuth subsalicylate exaggerates warfarin's anticoagulant response and its concurrent use during warfarin therapy should be avoided.

    Reports on clinical measurements of bone mineral density (BMD) in prostate cancer patients undergoing intermittent androgen suppression therapy (IAS) that allows for hormonal recovery between treatment cycles indicate decreased osteoporosis compared to continuous androgen suppression therapy (CAS). In the present study the effect of IAS on bone metabolism by determinations of CrossLaps, a biochemical marker of collagen degradation, were examined. In total 100 IAS treatment cycles of 75 patients with prostate cancer stages ≥ pT2 were studied. Clinical data and monthly laboratory tests (testosterone, prostate-specific antigen; PSA) of these patients were monitored together with measurements of C-terminal telopeptide collagen fragments using CrossLaps® ELISA assays. During phases of androgen suppression (AS) lasting for 9 months serum testosterone (<1 ng/mL) and PSA (<2 ng/mL) levels were reversibly reduced, indicating partial growth arrest and apoptotic regression of the prostatic tumors. Serum CrossLaps concentrations peaked at the last 2 months of the AS phases (0.91 ± 0.25 μg/L; mean ± SEM) and were reduced below initial values (0.21 ± 0.43 versus baseline of 0.43 ± 0.06 μg/L) during therapy cessation periods until tumor progression-related increases. Measurements of the serum concentration of CrossLaps in prostate cancer patients receiving IAS indicated that treatment cessation phases rapidly reversed increased bone degradation associated with AS phases, in strong agreement with the clinical observations reporting reduced loss of BMD in IAS when compared to CAS. In terms of clinical outcomes, IAS seems to be as effective as CAS while showing reduced side effects, as demonstrated here by the reduction of androgen-induced bone matrix degradation.

    Background Neoadjuvant chemoradiation therapy (CRT) is an important management strategy in rectal carcinoma. Different systems grading response have shown varying prognostic influence. Methods To analyze the prognostic influence of pathological response in a series of 183 patients with rectal carcinoma receiving neoadjuvant therapy. To determine the prognostic significance of the histopathological patterns of response. Results A total of 183 patients from two hospitals. The concordance rate between pathologists was good. In total, 18% of the patients showed grade 0 (complete response), 31.7% grade 1, 19.2% grade 2 and 31.1% grade 3 regression. T down-staging was found in 51.9% of the cases. 46 patients recurred and 18 died of disease (median follow-up time: 39 months). We found a statistically significant association between pathological response and pT stage and down-staging. Inflammatory reaction in the tumor bed was significantly associated to regression and prognosis. Cox’s multivariate analysis of survival revealed that down-staging and presence of mucin pools in the tumor bed behaved as significant predictors of recurrence and regression grade and mucin pools as significant predictors of survival. Conclusions Pathological response is an important surrogate marker of prognosis in some large series, but results are varying. There are many systems to grade regression and this makes it difficult to compare the results by different groups. It is important to report the specific pattern of response, for some of them may have prognostic relevance. We feel there is an urgent need to develop standarized protocols and employ a universal regression scheme if we intend to use this factor to guide therapy. PMID:28280608

    In order to achieve optimal benefits of antiretroviral therapy (ART), caregivers of children receiving ART are required to attend routine clinic visits monthly and administer medication to the child as prescribed. Yet, the level of adherence to these behaviours varies considerably in many settings. As a way to achieve optimal adherence in rural KwaZulu-Natal, caregivers are required to attend routine counselling sessions at HIV treatment clinics that are centred on imparting information, motivation, and behavioural skills related to medication administration. According to the information-motivation-behavioural skills model, information related to adherence, motivation, and behavioural skills are necessary and fundamental determinants of adherence to ART. The purpose of the study was to observe and document the content of adherence counselling sessions that caregivers attending rural clinics in KwaZulu Natal receive. We observed 25 adherence counselling sessions, which lasted on average 8.1 minutes. Counselling typically consisted of counsellors recording patient attendance, reporting CD4 count and viral load results to caregivers, emphasising dose times, and asking caregivers to name their medications and dosage amounts. Patients were seldom asked to demonstrate how they measure the medication. They were also not probed for problems regarding treatment, even when an unsuppressed VL was reported to a caregiver. This paper calls attention to the sub-optimal level of counselling provided to patients on ART and the urgent need to standardise and improve the training, support, and debriefing provided to counsellors.

    The aim of this review was to examine the toxicity profile of adjuvant interferon (IFN) alfa-2b in melanoma patients from a nursing perspective and to summarize practical information to guide the effective management of common IFN toxicities to improve patient comfort. This is a narrative summary of both research and review articles identified by searching PubMed, National Cancer Institute, and American Cancer Society websites. It also assesses recognized guidelines on the management of adjuvant IFN toxicity relevant to nurses who are caring for patients receiving adjuvant IFN therapy. Adjuvant high-dose IFN alfa-2b (HDI) as compared with observation significantly prolongs relapse-free survival in patients with melanoma at high risk for recurrence after surgical resection; however, treatment compliance and patient quality of life can be compromised by its toxicity profile. HDI toxicities affect a number of organ systems and the majority of patients will experience some side effects. Common toxicities such as flu-like symptoms, fatigue, anorexia, neuropsychiatric symptoms, and laboratory abnormalities are discussed, along with both pharmacological and nonpharmacological management strategies. The considerable side effects of HDI can be managed using established strategies. Oncology nurses play a significant role in the management of patients with melanoma receiving adjuvant HDI, and their prompt recognition of side effects, together with an understanding of effective pharmacological and nonpharmacological interventions, will improve patient comfort; this has the potential to positively influence treatment adherence and completion of the recommended treatment course.

  3. Daily application of transdermal fentanyl patches in patients receiving hyperbaric oxygen therapy.

    Hyperbaric oxygen therapy (HBOT) is a treatment for a variety of conditions, particularly nonhealing wounds. The treatment requires the inhalation of pure oxygen in a sealed chamber that is pressurized to 1.5 to 3 times that of normal atmospheric pressure. HBOT safety protocols require all transdermal products to be removed prior to entrance into the hyperbaric chamber, and many institutional policies state that removed patches are not to be reapplied. Limited data are available regarding the use of transdermal fentanyl patches in patients undergoing HBOT. For such patients, the patch would need to be changed on a daily basis. Although the recommended dosing interval is 72 hours, many references discuss the use of 48-hour intervals in select patients, and no published reference recommends dosing intervals shorter than 48 hours. The authors evaluated the clinical safety and efficacy parameters for two patients receiving daily application of transdermal fentanyl while receiving HBOT. Patient 1 was a 47-year-old female with diabetes mellitus, sepsis, and left foot wound with toe necrosis. Complicating her management was the presence of chronic pain syndrome secondary to fibromyalgia. Patient 2 was a 70-year-old female with paralysis secondary to spinal fracture who presented with a stage IV sacral pressure ulcer, who was later diagnosed with osteomyelitis. Both patients were successfully managed with daily application of fentanyl transdermal patch.

    Androgen deprivation therapy (ADT) results in testosterone suppression, a hypothesized mechanism linking ADT to depressive symptoms. This study investigated the relationship between ADT and the risk of subsequently being diagnosed with depressive disorder (DD) during a 3-year follow-up period. The patient sample for this population-based, retrospective cohort study was retrieved from the Taiwan Longitudinal Health Insurance Database 2005. We included all 1714 patients aged over 40 years with a first-time diagnosis of prostate cancer (PC) during 2001 to 2010 who did not have an orchiectomy. Among them, we defined 868 patients who received ADT during the 3-year follow-up period as the study group, and 846 patients who did not receive ADT as the comparison group. The incidence rates of DD per 1000 person-years were 13.9 (95% confidence interval (CI): 9.5~19.6) and 6.7 (95% CI: 3.7~11.0), respectively. Cox proportional hazard regressions showed that the adjusted hazard ratio for DD for ADT recipients was 1.93 (95% CI: 1.03~3.62) relative to the comparison group. This study presents epidemiological evidence of an association between ADT and a subsequent DD diagnosis. PMID:28253340

    We conducted a cross sectional study of the outpatient medical records of 1000 HIV-infected patients receiving antiretroviral therapy (ART) in 2011 to determine the incidence of clinically significant drug interactions (CSDI). The severities of the CSDI were graded following the Micromedex" 2.0 database and the Department of Health and Human Services (DHHS) 2012 HIV treatment guidelines. Three hundred thirty-five patients (34%) had 554 episodes of CSDI. Of which 337 episodes (61%), 163 episodes (29%) and 54 episodes (10%) had grades 2, 3 and 4 severity CSDI, respectively. The CSDI were caused by protease inhibitor (PI)-based drug regimens in 79%, by efavirenz-based regimens in 34% and by nevirapine-based regimens in 10% (p<0.001). The three most common grade 4 CSDI were: a PI with simvastatin (n=24), simvastatin with gemfibrozil (n=24) and didanosine with allopurinol (n=2). The three most common grade 3 CSDI were: a PI with a statin drug except simvastatin (n=56), fenofibrate with a statin drug (n=28) and amlodipine with simvastatin (n=14). On multivariate analysis, risk factors associated with CSDI were: receiving a PI-based regimen (OR 14.44; 95% CI: 9.10-22.88), having dyslipidemia (OR 3.94; 95% CI: 1.89-8.21), having >5 items prescribed at a time (OR 1.80; 95% CI: 1.23-2.63), seeing a doctor >4 times a year (OR 1.72; 95% CI: 1.20-2.46), having hypertension (OR 0.60; 95% CI: 0.37-0.98), having a duration of receiving ART of >5 years (OR 0.46; 95% CI: 0.28-0.77) and having a CD4 count of >200 cells/mm3 (OR 0.46; 95%CI: 0.26-0.84). CSDI were common among HIV-infected patients receiving ARV in our outpatient clinic. Patients having a low CD, count, having dyslipidemia, receiving PI-based ART, having a frequent number of visits per year and having a large number of items prescribed at each visit had a greater chance of a CSDI.

    The present study is aimed to investigate in vitro thrombolytic activity of three Bangladeshi medicinal plants Averrhoa bilimbi (Oxalidiaceae), Clerodendrum viscosum (Verbanaceae) and Drynaria quercifolia (Polypodiaceae). Each the plant was extracted with methanol at room temperature and the concentrated methanolic extracts (MEF) were fractionated by the modified Kupchan partitioning method to render pet-ether soluble fraction (PESF), carbon tetrachloride soluble fraction (CTSF), chloroform soluble fraction (CSF) and aqueous soluble fraction (AQSF). To observe their thrombolytic potential, a prompt and swift method was involved where streptokinase and water were used as positive and negative control, respectively. Among the three plants, AQSF and PESF of D. quercifolia with CTSF of C. viscosum exhibited highest thrombolytic activity by clot lysis of 34.38%, 34.27% and 28.64%, respectively. Among other extracts A. bilimbi, C. viscosun and D.quercifolia showed significant percentage (%) of clot lysis compared to standard streptokinase (41.05%) while the negative control water revealed 3.31 % lysis of clot. From our findings it is observed that all the plants revealed remarkable thrombolytic activity. Therefore, steps should be taken to observe in vivo clot dissolving potential and to isolate active component(s) of these extracts.

    The Acute Myocardial Infarction STudy of ADenosine (AMISTAD) trial was designed to test the hypothesis that adenosine as an adjunct to thrombolysis would reduce myocardial infarct size. Reperfusion therapy for acute myocardial infarction (MI) has been shown to reduce mortality, but reperfusion itself also may have deleterious effects. The AMISTAD trial was a prospective, open-label trial of thrombolysis with randomization to adenosine or placebo in 236 patients within 6 h of infarction onset. The primary end point was infarct size as determined by Tc-99 m sestamibi single-photon emission computed tomography (SPECT) imaging 6+/-1 days after enrollment based on multivariable regression modeling to adjust for covariates. Secondary end points were myocardial salvage index and a composite of in-hospital clinical outcomes (death, reinfarction, shock, congestive heart failure or stroke). In all, 236 patients were enrolled. Final infarct size was assessed in 197 (83%) patients. There was a 33% relative reduction in infarct size (p = 0.03) with adenosine. There was a 67% relative reduction in infarct size in patients with anterior infarction (15% in the adenosine group vs. 45.5% in the placebo group) but no reduction in patients with infarcts located elsewhere (11.5% for both groups). Patients randomized to adenosine tended to reach the composite clinical end point more often than those assigned to placebo (22% vs. 16%; odds ratio, 1.43; 95% confidence interval, 0.71 to 2.89). Many agents thought to attenuate reperfusion injury have been unsuccessful in clinical investigation. In this study, adenosine resulted in a significant reduction in infarct size. These data support the need for a large clinical outcome trial.

    OBJECTIVE: To help family physicians who care for patients with acute stroke or who are involved in planning service delivery or resource allocation to understand recent developments in acute stroke care. QUALITY OF EVIDENCE: A MEDLINE search indicated that most data were derived from well designed, randomized, double-blind, placebo-controlled trials, including all the largest international studies and large systematic reviews. MAIN MESSAGE: Treatment of acute stroke with tissue plasminogen activator seems beneficial for certain patients with certain kinds of stroke. Because thrombolytic therapy is not without risk and requires substantial resources, it should be administered only by physicians trained in its use and in centres with the necessary experience and resources. Because time is important, an organized and efficient system of stroke care with collaboration between hospital and prehospital care providers and help from ordinary citizens is essential. CONCLUSION: Management of acute stroke is an emerging discipline; many potential therapies are still experimental. PMID:11570304

    Abstract In cancer patients treated for venous thromboembolism (VTE), including deep-vein thrombosis (DVT) and pulmonary embolism (PE), analyzing mortality associated with recurrent VTE or major bleeding is needed to determine the optimal duration of anticoagulation. This was a cohort study using the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) Registry database to compare rates of fatal recurrent PE and fatal bleeding in cancer patients receiving anticoagulation for VTE. As of January 2013, 44,794 patients were enrolled in RIETE, of whom 7911 (18%) had active cancer. During the course of anticoagulant therapy (mean, 181 ± 210 days), 178 cancer patients (4.3%) developed recurrent PE (5.5 per 100 patient-years; 95% CI: 4.8–6.4), 194 (4.7%) had recurrent DVT (6.2 per 100 patient-years; 95% confidence interval [CI]: 5.3–7.1), and 367 (8.9%) bled (11.3 per 100 patient-years; 95% CI: 10.2–12.5). Of 4125 patients initially presenting with PE, 43 (1.0%) died of recurrent PE and 45 (1.1%) of bleeding; of 3786 patients with DVT, 19 (0.5%) died of PE, and 55 (1.3%) of bleeding. During the first 3 months of anticoagulation, there were 59 (1.4%) fatal PE recurrences and 77 (1.9%) fatal bleeds. Beyond the third month, there were 3 fatal PE recurrences and 23 fatal bleeds. In RIETE cancer patients, the rate of fatal recurrent PE or fatal bleeding was much higher within the first 3 months of anticoagulation therapy. PMID:26266353

    Purpose Hepatitis C virus (HCV) infection is associated with increased systemic oxidative stress, which leads to cardiovascular events, diabetes, and chronic kidney disease. Similarly, cataract is also associated with increased oxidative stress. The association between HCV infection and increased risk of cataract remains unclear. Methods A total of 11,652 HCV-infected patients and 46,608 age- and sex-matched non-HCV infected patients were identified during 2003–2011. All patient data were tracked until a diagnosis of cataract, death, or the end of 2011. Cumulative incidences and hazard ratios (HRs) were calculated. Results The mean follow-up durations were 5.29 and 5.86 years for the HCV and non-HCV cohorts, respectively. The overall incidence density rate for cataract was 1.36 times higher in the HCV cohort than in the non-HCV cohort (1.86 and 1.37 per 100 person-y, respectively). After adjusting for age, sex, comorbidities of diabetes, hypertension, hyperlipidemia, asthma, chronic obstructive pulmonary disease, coronary artery disease, and anxiety, patients with HCV infection had an increased risk of cataract compared with those without HCV infection [adjusted HR = 1.23, 95% confidence interval (CI) = 1.14–1.32]. HCV-infected patients receiving interferon–ribavirin therapy had a 1.83 times higher (95% CI = 1.40–2.38) risk of cataract than non-HCV infected patients did. Conclusion HCV infection, even without the complication of cirrhosis, is associated with an increased risk of cataract, and this risk is higher in HCV-infected patients undergoing interferon–ribavirin therapy.

    This study aimed to examine changes in physical symptom severity, functional status, supportive care needs, and related factors in oral cavity cancer patients during 6 months after beginning radiation therapy (RT) or concurrent chemotherapy and radiation therapy (CCRT). A prospective longitudinal study was conducted involving oral cavity cancer patients from an RT clinic at a medical center in northern Taiwan. Patients were assessed for supportive care needs and physical symptoms at five time points: before the beginning of RT or CCRT and at 1, 2, 3, and 6 months after beginning RT or CCRT. The generalized estimating equation was used to identify predictors of overall needs as well as six specific dimensions of needs. A total of 82 patients completed the 6 months of follow-up. Patients had moderate to high levels of supportive care needs over the 6 months. Although the highest information need was at the pretreatment phase, in general, the peak for overall and individual care needs was at 2 months since first receiving RT or CCRT. Patients without religious beliefs as well as those with higher educational level, functional level, overall physical symptom severity, and baseline anxiety reported more supportive care needs. Anxiety level before treatment was the most common factor across most supportive care needs. Individual physical symptoms, including fatigue, swallowing difficulty, and oral mucositis, were significantly related to higher physical and daily living needs. A systematic clinical assessment to detect patients' care needs is necessary to improve the provision of timely cancer care and meet patients' healthcare needs.

    Even with current highly active antiretroviral therapy, individuals with AIDS continue to exhibit important nutritional deficits and reduced levels of albumin and hemoglobin, which may be directly related to their cluster of differentiation 4 (CD4) cell counts. The aim of this study was to characterize the nutritional status of individuals with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and relate the findings to the albumin level, hemoglobin level and CD4 cell count. Patients over 20 years of age with AIDS who were hospitalized in a university hospital and were receiving antiretroviral therapy were studied with regard to clinical, anthropometric, biochemical and sociodemographic characteristics. Body mass index, percentage of weight loss, arm circumference, triceps skinfold and arm muscle circumference were analyzed. Data on albumin, hemoglobin, hematocrit and CD4 cell count were obtained from patient charts. Statistical analysis was performed using Fisher's exact test, Student's t-test for independent variables and the Mann-Whitney U-test. The level of significance was set to 0.05 (α = 5%). Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) 17.0 software for Windows. Of the 50 patients evaluated, 70% were male. The prevalence of malnutrition was higher when the definition was based on arm circumference and triceps skinfold measurement. The concentrations of all biochemical variables were significantly lower among patients with a body mass index of less than 18.5kg/m2. The CD4 cell count, albumin, hemoglobin and hematocrit anthropometric measures were directly related to each other. These findings underscore the importance of nutritional follow-up for underweight patients with AIDS, as nutritional status proved to be related to important biochemical alterations.

    Serious gram-positive bacterial infections are an important cause of morbidity and mortality among older adults and can present significant challenges to clinicians. Data evaluating the safety and effectiveness of newer agents in this population are limited. Daptomycin is a lipopeptide with activity against resistant gram-positive organisms. To better understand the overall safety and effectiveness of daptomycin in older adults (≥66 years of age), the authors reviewed the data that were collected as part of an ongoing registry maintained by Cubist Pharmaceuticals, Inc. (Lexington, Massachusetts), the manufacturer of daptomycin. The Cubicin Outcomes Registry and Experience (CORE) is a multicenter, retrospective registry designed to collect postmarketing clinical data on patients who received daptomycin. The CORE data collected from 58 institutions across the United States between January 1, 2005, and December 31, 2007, were analyzed to better understand the overall safety profile of daptomycin and the clinical outcomes of older adults who were treated with this agent. Patients were considered to be nonevaluable if the medical record did not contain sufficient information to determine response at the end of therapy. Nonevaluable patients were excluded from the clinical outcome analysis but included in the safety analysis. The registry contained 1073 patients aged ≥66 years who received daptomycin; 23.8% (255/1073) were ≥81 years of age. Overall, 18.1% (194/1073) of patients experienced 324 adverse events, and 6.2% (67/1073) of patients experienced 97 adverse events that were considered possibly related to treatment with daptomycin. The most frequently reported adverse events that were considered possibly treatment related included creatine phosphokinase (CPK) elevations, gastrointestinal disorders, and skin rashes. Among the 67 patients who experienced ≥1 adverse event that was possibly related to daptomycin, 30 discontinued therapy due to the adverse event

    Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patients (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.

    People with a disability living in rural areas commonly experience difficulty in accessing therapy services. Information and Communication Technologies (ICT) may have the potential to provide occupational therapy services remotely through two-way visual interactions. The aim of this qualitative study was to understand the perspectives of carers of a person with a disability living in rural New South Wales (NSW) on the use of ICT for occupational therapy service delivery. Individual semi-structured telephone interviews were conducted with 11 carers of persons with a disability living in rural NSW. Participants were asked about their use of technology, therapy experiences and their attitudes towards using ICT to receive occupational therapy for their son/daughter. Data were analysed via constant comparison and thematic analysis. Participants were willing to use ICT to enhance their current access to therapy based on their in-depth knowledge of their son or daughter and their prior experiences with therapy and technology. For ICT to work for occupational therapy, participants identified the need for support and access prior to, during and between ICT sessions. From the carers' perspectives, ICT has the potential to increase access to occupational therapy services for people with a disability who live in rural NSW. Occupational therapists could benefit from eliciting the experiences, knowledge and willingness of rural carers to deliver therapy via ICT, thereby supplementing and enhancing in-person service delivery. © 2016 Occupational Therapy Australia.

    This paper's goal is to assess secondary neutron doses received by paediatric patients treated for intracranial tumours using a 178 MeV proton beam. The MCNPX Monte Carlo model of the proton therapy facility, previously validated through experimental measurements for both proton and neutron dosimetry, was used. First, absorbed dose was calculated for organs located outside the clinical target volume using a series of hybrid computational phantoms for different ages and considering a realistic treatment plan. In general, secondary neutron dose was found to decrease as the distance to the treatment field increases and as the patient age increases. In addition, secondary neutron doses were studied as a function of the beam incidence. Next, neutron equivalent dose was assessed using organ-specific energy-dependent radiation weighting factors determined from Monte Carlo simulations of neutron spectra at each organ. The equivalent dose was found to reach a maximum value of ∼155 mSv at the level of the breasts for a delivery of 49 proton Gy to an intracranial tumour of a one-year-old female patient. Finally, a thorough comparison of the calculation results with published data demonstrated the dependence of neutron dose on the treatment configuration and proved the need for facility-specific and treatment-dependent neutron dose calculations.

    To evaluate the effect of haematological alterations resulting from antiretroviral therapy (ART) on the diagnosis of thalassaemia carriers in HIV-1-infected Thai patients. Complete blood cell counts, osmotic fragility (OF) test and haemoglobin (Hb)-A(2) values were measured in blood samples of 52 antiretroviral-treated and 14 untreated HIV-1-infected patients. Data were analysed according to thalassaemia type and ART. Sixteen patients carried at least one of the investigated thalassaemia types and most of them (87.5%) received ART. Their red cell indices [mean corpuscular Hb (MCH), mean corpuscular Hb concentration (MCHC) and red blood cell distribution width (RDW)], OF test and Hb-A(2) values were observed within the critical criteria of each thalassaemia type. Normocytic red cells were observed in alpha-thalassaemia and Hb-E trait. Among HIV-1-infected patients who are non-thalassaemia carriers, higher values of Hb-A(2), MCH, macrocytosis and lower red cell counts were observed in the treated group. Values of RDW, MCHC and OF test for treated and untreated groups were in the normal range. Five treated patients had Hb-A(2) values within the critical criteria of beta-thalassaemia carriers but beta-thalassaemia gene mutations were not observed by polymerase chain reaction analysis. ART can alter many haematological figures. Therefore, diagnosis of thalassaemia should be evaluated carefully in combination with those parameters.

    Aberrant Wnt signaling has been associated with many types of cancer. However, the association of inherited Wnt pathway variants with clinical outcomes in prostate cancer patients receiving androgen deprivation therapy (ADT) has not been determined. Here, we comprehensively studied the contribution of common single nucleotide polymorphisms (SNPs) in Wnt pathway genes to the clinical outcomes of 465 advanced prostate cancer patients treated with ADT. Two SNPs, adenomatous polyposis coli (APC) rs2707765 and rs497844, were significantly (p ≤ 0.009 and q ≤ 0.043) associated with both prostate cancer progression and all-cause mortality, even after multivariate analyses and multiple testing correction. Patients with a greater number of favorable alleles had a longer time to disease progression and better overall survival during ADT (p for trend ≤ 0.003). Additional, cDNA array and in silico analyses of prostate cancer tissue suggested that rs2707765 affects APC expression, which in turn is correlated with tumor aggressiveness and patient prognosis. This study identifies the influence of inherited variants in the Wnt pathway on the efficacy of ADT and highlights a preclinical rationale for using APC as a prognostic marker in advanced prostate cancer.

    Objective To explore the prevalence and features of HIV-associated neurocognitive disorders (HANDS) in Botswana, a sub-Saharan country at the center of the HIV epidemic. Design and Methods A cross sectional study of 60 HIV-positive individuals, all receiving highly active antiretroviral therapy (HAART), and 80 demographically matched HIV-seronegative control subjects. We administered a comprehensive neuropsychological test battery and structured psychiatric interview. The lowest 10th percentile of results achieved by control subjects was used to define the lower limit of normal performance on cognitive measures. Subjects who scored abnormal on three or more measures were classified as cognitively impaired. To determine the clinical significance of any cognitive impairment, we assessed medication adherence, employment, and independence in activities of daily living (ADL). Results HIV+ subjects were impaired for all cognitive-motor ability areas compared with matched, uninfected control subjects. Thirty seven percent of HIV+ patients met criteria for cognitive impairment. Conclusion These findings indicate that neurocognitive impairment is likely to be an important feature of HIV infection in resource-limited countries; underscoring the need to develop effective treatments for subjects with, or at risk of developing, cognitive impairment.

    We investigated the hypothesis that patients developing high-grade erythema of the breast skin during radiation treatment could be more likely to present increased levels of proinflammatory cytokines which may lead, in turn, to associated fatigue. Forty women with early stage breast cancer who received adjuvant radiotherapy were enrolled from 2007 to 2010. Fatigue symptoms, erythema, and cytokine levels (IL-1β, IL-2, IL6, IL-8, TNF-α, and MCP-1) were registered at baseline, during treatment, and after radiotherapy completion. Seven (17.5%) patients presented fatigue without associated depression/anxiety. Grade ≥2 erythema was observed in 5 of these 7 patients. IL-1β, IL-2, IL-6, and TNF-α were statistically increased 4 weeks after radiotherapy (P < 0.05). After the Heckman two-step analysis, a statistically significant influence of skin erythema on proinflammatory markers increase (P = 0.00001) was recorded; in the second step, these blood markers showed a significant impact on fatigue (P = 0.026). A seeming increase of fatigue, erythema, and proinflammatory markers was observed between the fourth and the fifth week of treatment followed by a decrease after RT. There were no significant effects of hormone therapy, breast volume, and anemia on fatigue. Our study seems to suggest that fatigue is related to high-grade breast skin erythema during radiotherapy through the increase of cytokines levels. PMID:24800238

    To explore the views of lay and professional stakeholders about the donation of cord blood to public banks in England and the policies surrounding it. Qualitative in-depth interviews were undertaken between April 2009 and August 2010 with 62 participants based in England who play a key role in cord blood banking and therapy. All interviews were recorded, transcribed in full, and coded and analysed thematically. Participants claimed pregnant women had a right to know of the value of cord blood. This highlighted the flaws of the existing donation infrastructure, which was portrayed as playing a significant role in determining public health. Participants called for a right to donate cord blood to readdress the inequity in healthcare services for pregnant women and transplant recipients. Donors maintained a sense of right over their donation when they discussed cord blood donation as potentially benefiting their family as well as society. In order to keep receiving donated body parts, tissue and blood, there is a need to take into account the way in which donation operates within a prevalent 'rights' discourse.

    2012-01-01

    In the past 3 decades, the number of immunocompromised children has increased steadily because of dramatic improvement in survival rates in certain malignancies as a result of intensive curative treatment regimens and an increase in the number of children undergoing life-saving hematopoietic stem cell transplantation (HSCT). Children receiving immunosuppressive therapy for cancer, as well as HSCT recipients, will benefit from vaccination but warrant close evaluation for a variety of reasons, such as the risk of developing severe infections, serious adverse events following certain vaccines, and decreased vaccine efficacy caused by poor immune response to vaccination. Various professional organizations have published vaccination guidelines for immunocompromised patients. Given their heterogeneity, recommendations for the immunization of immunocompromised patients may not be universally applicable. The safety of many commonly used vaccines has not been established in immunocompromised children. In addition, no large-scale vaccine studies have evaluated the clinical outcome of disease prevention in this population. All killed vaccines are generally safe, while live vaccines may be administered to immunocompromised children in select circumstances, depending on the degree of altered immunocompetence and the underlying primary condition. Healthcare providers should be knowledgeable about the indications, contraindications, and precautions for vaccine administration in immunocompromised patients. To protect immunocompromised patients, all family, household contacts, and healthcare workers should also be immunized with all routinely recommended vaccines. Pediatricians play a crucial role in identifying and effectively communicating the risks and benefits of vaccines to immunocompromised patients and their parents. PMID:23049460

    The aim of this study was to determine the efficacy of two hepatitis C virus (HCV) real-time PCR assays, the COBAS AmpliPrep/COBAS TaqMan HCV test (CAP/CTM) and the Abbott RealTime HCV test (ART), for predicting the clinical outcomes of patients infected with HCV who received telaprevir (TVR)-based triple therapy or daclatasvir/asunaprevir (DCV/ASV) dual therapy. The rapid virological response rates in patients receiving TVR-based triple therapy were 92% (23/25) and 40% (10/25) for CAP/CTM and ART, respectively. The false omission rate (FOR) of ART was 93.3% (14/15), indicating that CAP/CTM could accurately predict clinical outcome in the early phase. In an independent examination of 20 patients receiving TVR-based triple therapy who developed viral breakthrough or relapse, the times to HCV disappearance by ART were longer than by CAP/CTM, whereas the times to HCV reappearance were similar. In an independent experiment of WHO standard HCV RNA serially diluted in serum containing TVR, the analytical sensitivities of CAP/CTM and ART were similar. However, cell cultures transfected with HCV and grown in medium containing TVR demonstrated that ART detected HCV RNA for a longer time than CAP/CTM. Similar results were found for 42 patients receiving DCV/ASV dual therapy. The FOR of ART was 73.3% (11/15) at week 8 after initiation of therapy, indicating that ART at week 8 could not accurately predict the clinical outcome. In conclusion, although CAP/CTM and ART detected HCV RNA with comparable analytical sensitivity, CAP/CTM might be preferable for predicting the clinical outcomes of patients receiving protease inhibitor-based therapy.

    During September–November 2014, the New York State Department of Health (NYSDOH) was notified of five New York state residents who had tested seropositive for Coxiella burnetii, the causative agent of Q fever. All five patients had symptoms compatible with Q fever (e.g., fever, fatigue, chills, and headache) and a history of travel to Germany to receive a medical treatment called "live cell therapy" (sometimes called "fresh cell therapy") in May 2014. Live cell therapy is the practice of injecting processed cells from organs or fetuses of nonhuman animals (e.g., sheep) into human recipients. It is advertised to treat a variety of health conditions. This practice is unavailable in the United States; however, persons can travel to foreign locations to receive injections. Local health departments interviewed the patients, and NYSDOH notified CDC and posted a report on CDC’s Epidemic Information Exchange to solicit additional cases. Clinical and exposure information for each patient was reported to the Robert Koch Institute in Germany, which forwarded the information to local health authorities. A Canada resident who also received live cell therapy in May 2014 was diagnosed with Q fever in July 2014. Clinicians should be aware of health risks, such as Q fever and other zoonotic diseases, among patients with a history of receiving treatment with live cell therapy products.

    Despite the fact that magnetic thrombolytic composites is an emerging area, all known so far systems are based on the similar mechanism of action: thrombolytic enzyme releases from the magnetic carrier leaving non-active matrix, thus making the whole system active only for a limited period of time. Such systems often have very complex structure organization and composition, consisting of materials not approved for parenteral injection, making them poor candidates for real clinical trials and implementation. Here we report, for the first time, the production of thrombolytic magnetic composite material with non-releasing behavior and prolonged action. Obtained composite shows good thrombolytic activity, consists of fully biocompatible materials and could be applied as infinitely active thrombolytic coatings or magnetically-targetable thrombolytic agents.

    Despite the fact that magnetic thrombolytic composites is an emerging area, all known so far systems are based on the similar mechanism of action: thrombolytic enzyme releases from the magnetic carrier leaving non-active matrix, thus making the whole system active only for a limited period of time. Such systems often have very complex structure organization and composition, consisting of materials not approved for parenteral injection, making them poor candidates for real clinical trials and implementation. Here we report, for the first time, the production of thrombolytic magnetic composite material with non-releasing behavior and prolonged action. Obtained composite shows good thrombolytic activity, consists of fully biocompatible materials and could be applied as infinitely active thrombolytic coatings or magnetically-targetable thrombolytic agents.

    To determine factors associated with patients refusing IV t-PA for suspected acute ischemic stroke (AIS), and to compare the outcomes of patients who refused t-PA (RT) with those treated with t-PA. Patients who were treated with and refused t-PA at our stroke center were identified retrospectively. Demographics, clinical presentation, and outcome measures were collected and compared. Clinical outcome was defined as excellent (mRS: 0-1), good (mRS: 0-2), and poor (mRS: 3-6). Over 7·5 years, 30 (4·2%) patients refused t-PA. There were no demographic differences between the treated and RT groups. The rate of RT decreased over time (OR 0·63, 95% CI 0·50-0·79). Factors associated with refusal included a later symptom onset to emergency department presentation time (OR 1·02, 95% CI 1·01-1·03), lower NIHSS (OR 1·11, 95% CI 1·03-1·18), a higher proportion of stroke mimics (OR 17·61, 95% CI 6·20-50·02) and shorter hospital stay (OR 1·32, 95% CI 1·09-1·61). Among patients who were subsequently diagnosed with ischemic stroke, only length of stay was significantly shorter for refusal patients (OR 1·37, 95% CI 1·06-1·78). After controlling for mild strokes and stroke mimics, clinical outcome was not different between the groups (OR 1·61, 95% CI 0·69-3·73). The incidence of patients refusing t-PA has decreased over time, yet it may be a cause for t-PA under-utilization. Patients with milder symptoms were more likely to refuse t-PA. Refusal patients presented later to the hospital and had shorter hospital stays. One out of six refusal patients (16·6%) had a stroke mimic. © 2012 The Authors.

    To assess the safety and immunogenicity of live attenuated yellow fever (YF) 17D vaccine in adults receiving systemic corticosteroid therapy. All adult travelers on systemic corticosteroid therapy who had received the YF17D vaccine in 24 French vaccination centers were prospectively enrolled and matched with healthy controls (1:2) on age and history of YF17D immunization. Safety was assessed in a self-administered standardized questionnaire within 10 days after immunization. YF-specific neutralizing antibody titers were measured 6 months after vaccination in patients receiving corticosteroids. Between July 2008 and February 2011, 102 vaccine recipients completed the safety study (34 receiving corticosteroids and 68 controls). The median age was 54.9 years (interquartile range [IQR] 45.1-60.3 years) and 45 participants had a history of previous YF17D immunization. The median time receiving corticosteroid therapy was 10 months (IQR 1-67 months) and the prednisone or equivalent dosage was 7 mg/day (IQR 5-20). Main indications were autoimmune diseases (n = 14), rheumatoid arthritis (n = 9), and upper respiratory tract infections (n = 8). No serious adverse event was reported; however, patients receiving corticosteroids reported more frequent moderate/severe local reactions than controls (12% and 2%, respectively; relative risk 8.0, 95% confidence interval 1.4-45.9). All subjects receiving corticosteroids who were tested (n = 20) had neutralizing antibody titers >10 after vaccination. After YF17D immunization, moderate/severe local reactions may be more frequent in patients receiving systemic corticosteroid therapy. Immunogenicity seems satisfactory. Large-scale studies are needed to confirm these results. Copyright © 2013 by the American College of Rheumatology.

    Background: Thrombolytic therapy has become a conventional treatment for acute myocardial infarction (AMI), yet currently, clinically prescribed thrombolytic drugs have problems such as delayed action and other side effects. Fibrinolytic enzymes have attracted interest as thrombolytic agents because of their efficiency in the fibrinolytic process, including plasmin activation. Nattokinase (NK) is a potent fibrinolytic agent for thrombosis therapy. Objectives: The aim of this study was to enhance the production of NK from Pseudomonas aeruginosa CMSS by media optimization and strain improvement. Materials and Methods: In the present study, a potent NK-producing strain was isolated from cow milk and identified. To enhance the yield of NK, effect of various parameters such as pH, temperature, carbon source, nitrogen source and inoculum size were optimized. Strain improvement of P. aeruginosa CMSS was done by random UV-mutagenesis. Nattokinase was partially purified and the activity was determined by the casein digestion method, blood clot lysis and fibrin degradation assay. Results: Based on morphological, biochemical and molecular characterization, the strain was confirmed as P. aeruginosa (GenBank accession number: JX112657), designated as P. aeruginosa CMSS. The optimum condition at pH 7 and temperature at 25˚C showed activity of NK as 1514 U mL-1 and 1532 U mL-1, respectively. Sucrose as the carbon source and shrimp shell powder (SSP) as the nitrogen source expressed NK activity of 1721 U mL-1 and 2524 U mL-1, respectively. At 1% inoculum size, the maximum rate of enzyme production was achieved with 2581 U mL-1. The NK activity of the mutant strain UV60 was 4263 U mL-1, indicating a two-fold increase in activity compared to the wild strain (2581 UmL-1). Nattokinase produced from mutant strain P. aeruginosa CMSS UV60 showed 94% blood clot lysis at ten minutes. The degradation of fibrin clot by the produced NK was observed after two hours of incubation. Sodium

    Purpose: The purpose of this study was to evaluate the effect on freedom from biochemical failure (bNED) or disease-free survival (DFS) by adding hormone therapy (HT) to dose-escalated radiation therapy (HDRT). Methods and Materials: We used 883 analyzable prostate cancer patients who enrolled on Radiation Therapy Oncology Group (RTOG) 94-06, a Phase I/II dose escalation trial, and whose mean planning target volume dose exceeded 73.8 Gy (mean, 78.5 Gy; maximum, 84.3 Gy). We defined biochemical failure according to the Phoenix definition. Results: A total of 259 men started HT 2 to 3 months before HDRT, but not longer than 6 months, and 66 men with high-risk prostate cancer received HT for a longer duration. At 5 years, the biochemical failure rates after HDRT alone were 12%, 18%, and 29% for low-, intermediate-, and high-risk patients, respectively (p < 0.0001). Cox proportional hazards regression analysis adjusted for covariates revealed that pretreatment PSA level was a significant factor, whereas risk group, Gleason score, T-stage, and age were not. When the patients were stratified by risk groups, the Cox proportion hazards regression model (after adjusting for pretreatment PSA, biopsy Gleason score, and T stage) did not reveal a significant effect on bNED or DFS by adding HT to HDRT Conclusion: The addition of HT did not significantly improve bNED survival or DFS in all prostate cancer patients receiving HDRT, but did approach significance in high-risk patient subgroup. The result of this study is hypothesis generating and requires testing in a prospective randomized trial.

    Intravenous thrombolysis is the only therapy for acute ischemic stroke that is approved by the US Food and Drug Association. The use of telemedicine in stroke makes it possible to bring the expertise of academic stroke centers to underserved areas, potentially increasing the quality of stroke care. All consecutive admissions for stroke were reviewed for 1 year before telemedicine implementation and for variable periods thereafter. A retrospective review identified 2588 admissions for acute stroke between March 2005 and December 2008 at 12 hospitals participating in a telestroke network, including 919 patients before telemedicine was available and 1669 patients after telemedicine was available. The primary outcome measure was the rate of intravenous tissue plasminogen activator (IV tPA) use before and after telemedicine implementation. One hundred thirty-nine patients received IV tPA in both study phases, with 26 (2.8%) patients treated before starting telemedicine and 113 (6.8%) after starting telemedicine (P < .001). Incorrect treatment decisions occurred 7 times (0.39%), with 2 (0.2%) pretelemedicine and 5 (0.3%) posttelemedicine (P = .70). Arrivals within 3 hours from symptom onset were more frequent in the posttelemedicine compared to the pretelemedicine phases (55 [6%] vs 159 [9.5%]; P = .002). Among the patients treated with IV tPA, symptomatic intracranial hemorrhage occurred in 2 patients (1 [10.7%] pretelemedicine vs 1 [1.8%] posttelemedicine; P = .34). Telestroke implementation was associated with an increased rate of thrombolytic use in remote hospitals within the telemedicine network. Copyright © 2013 National Stroke Association.

    Patients treated with cranial radiation therapy (RT) are at risk for sensorineural hearing loss (SNHL). Although SNHL is often characterized as a delayed consequence of anticancer therapy, longitudinal reports of SNHL in childhood cancer survivors treated with contemporary RT are limited. We report the incidence, onset, severity, and long-term trajectory of SNHL among children receiving RT. Potential risk factors for SNHL were also identified. Serial audiologic testing was conducted on 235 pediatric patients who were treated with conformal or intensity-modulated RT as part of an institutional phase II trial for localized primary brain tumors, including craniopharyngioma, ependymoma, and juvenile pilocytic astrocytoma. All but one patient had measurable cochlear radiation dose (CRD) greater than 0 Gy. The median follow-up from RT initiation to latest audiogram was 9 years with a median of 11 post-RT audiograms per patient. Audiograms were classified by the Chang Ototoxicity Grading Scale. Progression was defined by an increase in Chang grade from SNHL onset to the most recent evaluation. At last evaluation, SNHL was prevalent in 14% of patients: 2.1% had mild and 11.9% had significant SNHL requiring hearing aids. Median time from RT to SNHL onset was 3.6 years (range, 0.4 to 13.2 years). Among 29 patients with follow-up evaluations after SNHL onset, 65.5% experienced continued decline in hearing sensitivity in either ear and 34.5% had no change. Younger age at RT initiation (hazard ratio [HR], 2.32; 95% CI, 1.21 to 4.46), higher CRD (HR, 1.07; 95% CI, 1.03 to 1.11), and cerebrospinal fluid shunting (HR, 2.02; 95% CI, 1.07 to 3.78) were associated with SNHL. SNHL is a late effect of RT that likely worsens over time. Long-term audiologic follow-up for a minimum of 10 years post-RT is recommended. © 2016 by American Society of Clinical Oncology.

    Patients with acute venous thromboembolism (VTE) are at increased risk for the development of subsequent arterial ischemic events unrelated to the diagnosis of VTE. Accurate identification of VTE patients at increased risk for ischemic events during the course of anticoagulation may help to select those who would potentially benefit from concomitant therapy with anticoagulants and antiplatelets. We used the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) Registry to assess the rate and severity of subsequent ischemic events (ie, stroke, myocardial infarction, lower limb amputation, or mesenteric ischemia) appearing during the course of anticoagulant therapy and tried to identify risk factors for these events. From February 2009 to March 2014, 23,370 patients were recruited: 12,397 initially presenting with pulmonary embolism (PE) and 10,973 with deep venous thrombosis. During the course of anticoagulation (mean, 9.2 months), 597 patients developed recurrent VTE, 652 bled, 162 had ischemic events (stroke, 86; myocardial infarction, 53; limb amputation, 13; mesenteric ischemia, 11), and 2063 died. Of these, 29 patients died of recurrent PE, 83 of bleeding, and 53 of the ischemic events. On multivariable analysis, cancer (hazard ratio [HR], 1.77; 95% confidence interval [CI], 1.21-2.61), chronic lung disease (HR, 1.54; 95% CI, 1.05-2.26), renal insufficiency (HR, 1.72; 95% CI, 1.25-2.36), anemia (HR, 1.54; 95% CI, 1.11-2.14), prior artery disease (HR, 1.84; 95% CI, 1.29-2.64), and diabetes (HR, 1.58; 95% CI, 1.10-2.27) independently predicted the risk for ischemic events. Most of these variables also predicted major bleeding (cancer, chronic lung disease, renal insufficiency, anemia, and prior artery disease) or recurrent PE (cancer, chronic lung disease, anemia, and prior artery disease). In patients receiving anticoagulation for VTE, the mortality due to PE recurrences was lower than the mortality due to ischemic events. Most independent predictors for

    Purpose Prostate cancer epidemiology has been marked overall by a downward risk migration over time. However, in some populations, both in the United States and abroad, many men are still diagnosed with high-risk and/or advanced disease. Primary androgen deprivation therapy (PADT) is frequently offered to these patients, and disease risk prediction is not well-established in this context. We compared risk features between large disease registries from the United States and Japan, and aimed to build and validate a risk prediction model applicable to PADT patients. Methods Data were analyzed from 13,740 men in the United States community-based Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) registry and 19,265 men in the Japan Study Group of Prostate Cancer (J-CaP) database, a national Japanese registry of men receiving androgen deprivation therapy. Risk distribution was compared between the two datasets using three well-described multivariable instruments. A novel instrument (Japan Cancer of the Prostate Risk Assessment [J-CAPRA]) was designed and validated to be specifically applicable to PADT patients, and more relevant to high-risk patients than existing instruments. Results J-CaP patients are more likely than CaPSURE patients to be diagnosed with high-risk features; 43% of J-CaP versus 5% of CaPSURE patients had locally advanced or metastatic disease that could not be stratified with the standard risk assessment tools. J-CAPRA—scored 0 to 12 based on Gleason score, prostate-specific antigen level, and clinical stage—predicts progression-free survival among PADT patients in J-CaP with a c-index of 0.71, and cancer-specific survival among PADT patients in CaPSURE with a c-index of 0.84. Conclusion The novel J-CAPRA is the first risk instrument developed and validated for patients undergoing PADT. It is applicable to those with both localized and advanced disease, and performs well in diverse populations. PMID:19667269

    The aim of our study was to evaluate the effect of BMI on the change in circulating sex hormone in postmenopausal women during 6 months of oral continuous combined low-dose hormone therapy (HT). Fifty postmenopausal women were allocated to receive daily one tablet containing combination of 17β-estradiol (1 mg)/norethindrone acetate (0.5 mg) for 6 months. Serum levels of follicle-stimulating hormone (FSH), estradiol, total testosterone, sex hormone-binding globulin (SHBG), free androgen index (FAI), free estrogen index (FEI), Δ4-androstendione (Δ4A), and dehydroepiandrosterone sulfate were assessed at baseline and at the end of 6 months. Mean absolute values and percent changes from baseline were compared between lean and overweight women. Mean FSH decreased and mean 17β-estradiol increased significantly in both groups (FSH lean: 82.3 ± 26.7 decreased to 45.0 ± 17.0 mIU/ml, P = 0.0001; FSH overweight: 85.5 ± 22.1 decreased to 52.3 ± 23.8 mIU/ml, P = 0.003; P between groups = 0.661; E2 lean: 23.24 ± 12.55 increased to 53.62 ± 28.29 pg/ml, P = 0.006; E2 overweight: 24.17 ± 10.88 increased to 68.36 ± 53.99 pg/ml, P = 0.0001; P between groups = 0.619). Lean individuals had statistically significant higher increments of FAI and specifically FEI compared to overweight (FEI lean; 0.14 ± 0.09 increased to 0.29 ± 0.14, P = 0.009; overweight 0.23 ± 0.18 increased to 0.52 ± 0.40, P = 0.126; P between groups = 0.034). Although BMI does not affect total 17β-estradiol changes, free sex steroid concentrations increase more steeply in lean compared to overweight women receiving oral low-dose HT.

    To identify the risk factors affecting hemorrhage after tooth extraction in patients receiving antiplatelet therapy, this study investigated the relation between various factors and hemorrhage events after tooth extraction. The records of 264 patients receiving antiplatelet therapy who underwent tooth extraction were retrospectively reviewed from 6 institutions belonging to the Japanese Study Group of Cooperative Dentistry with Medicine. Demographic information, hemorrhage events after tooth extraction, the presence or absence of comorbidities, antiplatelet agent, the use of preoperative antibiotics or nonsteroidal anti-inflammatory drugs, number of teeth extracted, serum creatinine level, estimated glomerular filtration rate, and alanine transaminase level were assessed. Risk factors for hemorrhage after tooth extraction were evaluated by univariate and multivariate analyses. The study population of 264 patients consisted of 153 men and 111 women with a mean age of 73.6 years (range, 24 to 96 yr). Six hundred ninety-four teeth were extracted (mean, 2.6 ± 2.3 teeth per patient). In patients receiving antiplatelet therapy, the frequency of hemorrhage after tooth extraction, including mild and self-controlled hemorrhages, was 17.4%. Univariate analysis showed that serum creatinine level and dual antiplatelet therapy were correlated with hemorrhage after tooth extraction (P = .001 and P = .049, respectively). Only serum creatinine was identified as an independent risk factor for hemorrhage after tooth extraction in patients receiving antiplatelet therapy (P = .037). The risk of hemorrhage after tooth extraction is increased in patients receiving dual antiplatelet therapy with or without chronic kidney disease. Local hemostatic treatments, such as at least suturing, are recommended. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

    To report on the anthropometric and growth status of children receiving renal replacement therapy (RRT) in Malaysia. Cross-sectional study with some retrospective elements. Outpatients' clinics in a major referral hospital in Malaysia. Fifteen renal transplants (mean age, 13.3 +/- 2.8 years) and 35 continuous ambulatory peritoneal dialysis (CAPD) patients (mean age, 12.6 +/- 3.0 years) participated. The RRT period ranged between 3 months to 6 years for both groups. None. Body mass index (BMI), percent body fat (% BF), triceps skinfold (TSF), mid upper-arm circumference (MUAC), arm muscle area (AMA), and z scores for height and weight. BMI for age indicated 7% of transplant subjects (TS) versus 40% of CAPD subjects were below the 5th percentile, whereas only 7% of TS were above the 95th percentile. % BF was higher for TS compared with the CAPD group for both sexes (boys, 19.5% and girls, 29.8% v boys, 12.4% and girls, 21.5%). Despite higher percentiles for TSF, transplant subjects still showed depleted muscle mass based on MUAC and AMA. z scores for height showed 93% of transplant subjects and 62% of CAPD subjects below -2 standard deviation (SD), whereas for weight these were 27% and 54%, respectively. Sixty-four percent of TS experienced catch-up growth for height and 86% for weight. These percentages were approximately halved for the CAPD group (32% and 43%, respectively). Patterns of growth and body composition appear distinctly different with the different RRT modalities. Serial anthropometric evaluation appears vital in pre- and post-RRT monitoring in pediatric renal populations. Copyright 2002 by the National Kidney Foundation, Inc.

    Hypothyroidism is associated with an adverse prognosis in cardiac patients in general and in particular in patients with heart failure (HF). The aim of this study was to evaluate the impact of hypothyroidism on patients with HF receiving cardiac resynchronization therapy (CRT). Additionally, the impact of level of control of hypothyroidism on risk of adverse events after CRT implantation was also evaluated. We included consecutive patients in whom a CRT device was implanted from April 2004 to April 2010 at our institution with sufficient follow-up data available for analysis; 511 patients were included (age 68.5±12.4 years, women 20.4%); 84 patients with a clinical history of hypothyroidism, on treatment with thyroid hormone repletion or serum thyroid-stimulating hormone level≥5.00 μU/ml, were included in the hypothyroid group. The patients were followed for up to 3 years after implant for a composite end point of hospitalization for HF, left ventricular assist device placement, or heart transplant and cardiac death; 215 composite end point events were noted in this period. In a multivariate model, hypothyroidism (hazard ratio [HR] 1.46, 95% confidence interval [CI] 1.027 to 2.085, p=0.035), female gender (HR 0.64, 95% CI 0.428 to 0.963, p=0.032), and creatinine (HR 1.26, 95% CI 1.145 to 1.382, p<0.001) were significantly associated with occurrence of the composite end point; 53.6% of patients with hypothyroidism at baseline developed the composite end point compared with 39.8% of those with euthyroidism (p=0.02). In conclusion, hypothyroidism is associated with a worse prognosis after CRT implantation.

    OBJECTIVE: To assess the frequency of shedding of polyomavirus JC virus (JCV) genotypes in urine of HIV-infected patients receiving highly active antiretroviral therapy (HAART). METHODS: Single samples of urine and blood were collected prospectively from 70 adult HIV-infected patients and 68 uninfected volunteers. Inclusion criteria for HIV-infected patients included an HIV RNA viral load < 1000 copies, CD4 cell count of 200-700 x 106 cells/l, and stable HAART regimen. PCR assays and sequence analysis were carried out using JCV-specific primers against different regions of the virus genome. RESULTS: JCV excretion in urine was more common in HIV-positive patients but not significantly different from that of the HIV-negative group [22/70 (31%) versus 13/68 (19%); P = 0.09]. HIV-positive patients lost the age-related pattern of JCV shedding (P = 0.13) displayed by uninfected subjects (P = 0.01). Among HIV-infected patients significant differences in JCV shedding were related to CD4 cell counts (P = 0.03). Sequence analysis of the JCV regulatory region from both HIV-infected patients and uninfected volunteers revealed all to be JCV archetypal strains. JCV genotypes 1 (36%) and 4 (36%) were the most common among HIV-infected patients, whereas type 2 (77%) was the most frequently detected among HIV-uninfected volunteers. CONCLUSION: These results suggest that JCV shedding is enhanced by modest depressions in immune function during HIV infection. JCV shedding occurred in younger HIV-positive persons than in the healthy controls. As the common types of JCV excreted varied among ethnic groups, JCV genotypes associated with progressive multifocal leukoencephalopathy may reflect demographics of those infected patient populations.

    Older patients with localized gastric adenocarcinoma (LGAC) have substantial postoperative morbidity and mortality; however, postoperative outcomes of the patients who receive preoperative chemotherapy and/or chemoradiation have not been reported. We examined the impact of age at baseline on potential predictors of postoperative outcomes. Patients with LGAC who were treated with chemotherapy and/or chemoradiation followed by surgery (n = 203) formed two groups: (1) ≥65 years old (n = 70) and (2) <65 years old (n = 133). We assessed postoperative morbidity and mortality as well as overall survival (OS) and progression-free survival (PFS). Potential predictors of 90-day postoperative outcomes were identified i) by age groups and ii) other clinical covariates. Descriptive statistics and survival analyses were utilized. 90-day postoperative morbidity was similar in older and younger patients (61 % vs 58 %; P = 0.655). 90-day mortality was similar (3 % vs 0 %; P = 0.118). Major Clavien grade III/IV complications were similar (17 % vs 12 %; P = 0.392). OS and PFS were also similar for both groups (P = 0.863 and P = 0.558, respectively). Other factors, such as Charlson comorbidity index (P < 0.001) and median operative time (P = 0.002) were strongly associated with postoperative complications. Our data show that older patients with LGAC generally have similar outcomes as do younger patients after preoperative therapy but comorbidity indices have significant impact on complications and the long-term outcomes rather than age.

    OBJECTIVE: To assess the frequency of shedding of polyomavirus JC virus (JCV) genotypes in urine of HIV-infected patients receiving highly active antiretroviral therapy (HAART). METHODS: Single samples of urine and blood were collected prospectively from 70 adult HIV-infected patients and 68 uninfected volunteers. Inclusion criteria for HIV-infected patients included an HIV RNA viral load < 1000 copies, CD4 cell count of 200-700 x 106 cells/l, and stable HAART regimen. PCR assays and sequence analysis were carried out using JCV-specific primers against different regions of the virus genome. RESULTS: JCV excretion in urine was more common in HIV-positive patients but not significantly different from that of the HIV-negative group [22/70 (31%) versus 13/68 (19%); P = 0.09]. HIV-positive patients lost the age-related pattern of JCV shedding (P = 0.13) displayed by uninfected subjects (P = 0.01). Among HIV-infected patients significant differences in JCV shedding were related to CD4 cell counts (P = 0.03). Sequence analysis of the JCV regulatory region from both HIV-infected patients and uninfected volunteers revealed all to be JCV archetypal strains. JCV genotypes 1 (36%) and 4 (36%) were the most common among HIV-infected patients, whereas type 2 (77%) was the most frequently detected among HIV-uninfected volunteers. CONCLUSION: These results suggest that JCV shedding is enhanced by modest depressions in immune function during HIV infection. JCV shedding occurred in younger HIV-positive persons than in the healthy controls. As the common types of JCV excreted varied among ethnic groups, JCV genotypes associated with progressive multifocal leukoencephalopathy may reflect demographics of those infected patient populations.

    Right hemisphere (RH) infarct patients have a tendency to begin visual scanning from the right side of a given stimulus. Our aim was to find out whether RH patients with (T+) or without (T-) thrombolytic treatment and healthy controls differ in their starting points in three cancellation tasks. Our sample comprised of 77 patients and 62 controls. Thirty-four patients received thrombolysis. Rightward orientation bias was more evident in the T- group than in the T+ group. The T+ group showed a robust tendency to start all cancellation tasks more often on the right side than the controls. Regardless of whether they had visual neglect, patients in the T+ group showed still defective rightward orienting, possibly indicating residual attentional problems. The analyses of starting points in visual cancellation tasks provide additional information on residual symptoms of attention difficulties after stroke.

    Abstract Background: Data regarding the clinical outcomes in patients with atrial fibrillation (AF) receiving dual antiplatelet therapy (DAPT) and an anticoagulant in addition to DAPT (DAPT + vitamin K antagonist [VKA]) after coronary stent implantation are still controversial. Therefore, in order to solve this issue, we aim to compare the adverse clinical outcomes in AF patients receiving DAPT and DAPT + VKA after percutaneous coronary intervention and stenting (PCI-S). Methods: Observational studies comparing the adverse clinical outcomes such as major bleeding, major adverse cardiovascular events, stroke, myocardial infarction, all-cause mortality, and stent thrombosis (ST) in AF patients receiving DAPT + VKA therapy, and DAPT after PCI-S have been searched from Medline, EMBASE, and PubMed databases. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to express the pooled effect on discontinuous variables, and the pooled analyses were performed with RevMan 5.3. Results: Eighteen studies consisting of a total of 20,456 patients with AF (7203 patients received DAPT + VKA and 13,253 patients received DAPT after PCI-S) were included in this meta-analysis. At a mean follow-up period of 15 months, the risk of major bleeding was significantly higher in DAPT + VKA group, with OR 0.62 (95% CI 0.50–0.77, P < 0.0001). There was no significant differences in myocardial infarction and major adverse cardiovascular event between DAPT + VKA and DAPT, with OR 1.27 (95% CI 0.92–1.77, P = 0.15) and OR 1.17 (95% CI 0.99–1.39, P = 0.07), respectively. However, the ST, stroke, and all-cause mortality were significantly lower in the DAPT + VKA group, with OR 1.98 (95% CI 1.03–3.81, P = 0.04), 1.59 (95% CI 1.08–2.34, P = 0.02), and 1.41 (95% CI 1.03–1.94, P = 0.03), respectively. Conclusion: At a mean follow-up period of 15 months, DAPT + VKA was associated with significantly lower risk of stroke, ST, and

    Objectives We investigated incidence and risk factors for postextraction bleeding in patients receiving warfarin and those not receiving anticoagulation therapy. Design Cross-sectional, multicentre, observational study. Setting 26 hospitals where an oral surgeon is available. Participants Data on 2817 teeth (from 496 patients receiving warfarin, 2321 patients not receiving warfarin; mean age (SD): 62.2 (17.6)) extracted between 1 November 2008 and 31 March 2010, were collected. Warfarin-receiving patients were eligible when prothrombin time–international normalised ratio (PT-INR) measured within 7 days prior to the extraction was less than 3.0. Interventions Simple dental extraction was performed, and incidence of postextraction bleeding and comorbidities were recorded. Primary and secondary outcome measures Postextraction bleeding not controlled by basic haemostasis procedure was clinically significant. Results Bleeding events were reported for 35 (7.1%) and 49 (2.1%) teeth, of which 18 (3.6%) and 9 (0.4%) teeth were considered clinically significant, in warfarin and non-warfarin groups, respectively, the difference between which was 3.24% (CI 1.58% to 4.90%). The incidence rates by patients were 2.77% and 0.39%, in warfarin and non-warfarin groups, respectively (incidence difference 2.38%, CI 0.65% to 4/10%). Univariate analyses showed that age (OR 0.197, p=0.001), PT-INR (OR 3.635, p=0.003), mandibular foramen conduction anaesthesia (OR 4.854, p=0.050) and formation of abnormal granulation tissue in extraction socket (OR 2.900, p=0.031) significantly correlate with bleeding incidence. Multivariate analysis revealed that age (OR 0.126, p=0.001), antiplatelet drugs (OR 0.100, p=0.049), PT-INR (OR 7.797, p=0.001) and history of acute inflammation at extraction site (OR 3.722, p=0.037) were significant risk factors for postextraction bleeding. Conclusions Our results suggest that there is slight but significant increase in the incidences of postextraction

    Antiplatelet therapy is the standard of care for the secondary prevention of acute coronary syndrome and ischemic stroke, especially after coronary intervention. However, this therapy is associated with bleeding complications such as gastrointestinal bleeding, which is one of the most common life-threatening complications. Early endoscopy is recommended for most patients with acute upper gastrointestinal bleeding. After successful endoscopic hemostasis, immediate resumption of antiplatelet therapy with proton-pump inhibitors (PPIs) is recommended to prevent further ischemic events. PPI prophylaxis during antiplatelet therapy reduces the risk of upper gastrointestinal bleeding. The potential negative metabolic interaction between PPIs and clopidogrel is still unclear.

    It has been reported that patients receiving renal replacement therapy (RRT), including dialysis and kidney transplantation, tend to have an increased risk of cancer; however, studies on the degree of this risk have remained inconclusive. The present meta-analysis was therefore performed to quantify the cancer risk in patients with RRT. Cohort studies assessing overall cancer risk in RRT patients published before May 29, 2015 were included following systematic searches with of PubMed, EMBASE and the reference lists of the studies retrieved. Random-effects meta-analyses were used to pool standardized incidence rates (SIRs) with 95% confidence intervals (CIs). Heterogeneity tests, sensitivity analyses and publication bias assessment were performed. A total of 18 studies including 22 cohort studies were eventually identified, which comprised a total of 1,528,719 patients. In comparison with the general population, the pooled SIR for patients with dialysis including non-melanoma skin cancer (NMSC), dialysis excluding NMSC, transplantation including NMSC, transplantation excluding NMSC and RRT were 1.40 (95% CI, 1.36–1.45), 1.35 (95% CI, 1.23–1.50), 3.26 (95% CI, 2.29–4.63), 2.08 (95% CI, 1.73–2.50) and 2.01 (95% CI, 1.70–2.38), respectively. The cancer risk was particularly high in subgroups of large sample size trials, female patients, younger patients (age at first dialysis, 0–34 years; age at transplantation, 0–20 years), the first year of RRT and non-Asian transplant patients. A significant association was also found between RRT and the majority of organ-specific cancers. However, neither dialysis nor transplantation was associated with breast, body of uterus, colorectal or prostate cancer. Significant heterogeneity was found regarding the association between RRT and overall cancer as well as the majority of site-specific cancer types. However, this heterogeneity had no substantial influence on the pooled SIR for overall cancer in RRT according to the

  12. Exacerbations in patients with chronic obstructive pulmonary disease receiving physical therapy: a cohort-nested randomised controlled trial

    PubMed Central

    2014-01-01

    Background Physical exercise training aims at reducing disease-specific impairments and improving quality of life in patients with chronic obstructive pulmonary disease (COPD). COPD exacerbations in particular negatively impact COPD progression. Physical therapy intervention seems indicated to influence exacerbations and their consequences. However, information on the effect of physical therapy on exacerbation occurrence is scarce. This study aims to investigate the potential of a protocol-directed physical therapy programme as a means to prevent or postpone exacerbations, to shorten the duration or to decrease the severity of exacerbations in patients with COPD who have recently experienced an exacerbation. Besides, this study focuses on the effect of protocol-directed physical therapy on health status and quality of life and on cost-effectiveness and cost-utility in patients with COPD who have recently experienced an exacerbation. Methods/Design A prospective cohort of 300 COPD patients in all GOLD stages will be constructed. Patients will receive usual multidisciplinary COPD care including guideline-directed physical therapy. Patients in this cohort who have GOLD stage 2 to 4 (post-bronchodilator FEV1/FVC < 0.7 and FEV1 < 80% of predicted), who receive reimbursement by health insurance companies for physical therapy (post-bronchodilator Tiffeneau-index < 0.6) and who experience a COPD exacerbation will be asked within 56 days to participate in a cohort-nested prospective randomised controlled trial (RCT). In this RCT, the intervention group will receive a strict physical therapy programme for patients with COPD. This protocol-directed physical therapy (pdPT) will be compared to a control group that will receive sham-treatment, meaning no or very low-intensity exercise training (ST). An economic evaluation will be embedded in the RCT. Anthropometric measurements, comorbidities, smoking, functional exercise capacity, peripheral muscle strength

    The study determined pharmacist support on patients receiving multi-drug therapy for coronary heart disease by evaluating patient self-care ability, quality of life, and drug therapy compliance. In this study, ninety patients were randomly assigned to an experimental group (n=45) and a control group (n=45). The control group received conventional clinical care. The experimental group received clinical care plus pharmacist support that included medication review, patient education, lifestyle management, discharge guidance, and telephone follow-up. Eighty-five patients completed the study. Self-care ability and quality of life were evaluated before hospital discharge. The experimental group understood their condition better than the control group (P<0.05), the differences between the groups in understanding treatment goals, drug regimens, lifestyle modifications, psychogenic disorders, and satisfaction evaluations were more pronounced (P<0.01). At six-month follow-up, the difference between the groups in drug therapy compliance was P<0.01, as was success rate by intention-to-treat (77.8% vs. 48.9%) and per-protocol (81.4% vs. 52.4%). Two adverse drug reactions occurred in the experimental group and three in the control group. Pharmacist support improved self-care ability, quality of life, drug therapy compliance, and treatment success rate in coronary heart disease patients.

    Few studies to date have evaluated factors associated with the development of radiation pneumonitis (RP) in patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), especially in patients treated with contemporary radiation techniques. These patients represent a unique group owing to the often large radiation target volumes within the mediastinum and to the potential to receive several lines of chemotherapy that add to pulmonary toxicity for relapsed or refractory disease. Our objective was to determine the incidence and clinical and dosimetric risk factors associated with RP in lymphoma patients treated with intensity modulated radiation therapy (IMRT) at a single institution. We retrospectively reviewed clinical charts and radiation records of 150 consecutive patients who received mediastinal IMRT for HL and NHL from 2009 through 2013. Clinical and dosimetric predictors associated with RP according to Radiation Therapy Oncology Group (RTOG) acute toxicity criteria were identified in univariate analysis using the Pearson χ(2) test and logistic multivariate regression. Mediastinal radiation was administered as consolidation therapy in 110 patients with newly diagnosed HL or NHL and in 40 patients with relapsed or refractory disease. The overall incidence of RP (RTOG grades 1-3) was 14% in the entire cohort. Risk of RP was increased for patients who received radiation for relapsed or refractory disease (25%) versus those who received consolidation therapy (10%, P=.019). Several dosimetric parameters predicted RP, including mean lung dose of >13.5 Gy, V20 of >30%, V15 of >35%, V10 of >40%, and V5 of >55%. The likelihood ratio χ(2) value was highest for V5 >55% (χ(2) = 19.37). In using IMRT to treat mediastinal lymphoma, all dosimetric parameters predicted RP, although small doses to large volumes of lung had the greatest influence.

    The efficacy of thrombolytic therapy for acute ischemic stroke (AIS) decreases when the administration of tissue plasminogen activator (tPA) is delayed. Derived from Toyota Production System, lean production aims to create top-quality products with high-efficiency procedures, a concept that easily applies to emergency medicine. In this study, we aimed to determine whether applying lean principles to flow optimization could hasten the initiation of thrombolysis. A multidisciplinary team (Stroke Team) was organized to implement an ongoing, continuous loop of lean production that contained the following steps: decomposition, recognition, intervention, reengineering and assessment. The door-to-needle time (DNT) and the percentage of patients with DNT ≤ 60 min before and after the adoption of lean principles were used to evaluate the efficiency of our flow optimization. Thirteen patients with AIS in the pre-lean period and 43 patients with AIS in the lean period (23 in lean period I and 20 patients in lean period II) were consecutively enrolled in our study. After flow optimization, we reduced DNT from 90 to 47 min (p < 0.001(¤)). In addition, the percentage of patients treated ≤60 min after hospital arrival increased from 38.46 to 75.0 % (p = 0.015(¤)). Adjusted analysis of covariance confirmed a significant influence of optimization on delay of tPA administration (p < 0.001). The patients were more likely to have a good prognosis (mRS ≤ 2 at 90 days) after the flow optimization (30.77-75.00 %, p = 0.012(¤)). Our study may offer an effective approach for optimizing the thrombolytic flow in the management of AIS.

    In-hospital mortality is higher for certain medical conditions based on the time of presentation to the emergency department. The primary goal of this study was to determine whether patients with acute ischemic stroke who arrived to the emergency department during a nursing shift change had similar rates of thrombolytic use and functional outcomes compared with patients presenting during nonshift change hours. A retrospective review of patients with acute ischemic stroke presenting to the emergency department of a primary stroke center from 2005 through 2010. The time to notify the stroke team, perform a head CT scan, and to start intravenous or intra-arterial thrombolysis was assessed. Thrombolysis rates, mortality rate, discharge disposition, change in the National Institutes of Health Stroke Scale, and change in modified Barthel Index at 3 and 12 months were assessed. Of 3133 patients with acute ischemic stroke, 917 met criteria for inclusion. Arrival during nursing shift change, weekends, and July through September had no impact on process times, thrombolysis rates, and functional outcomes. Arrival at night did result in longer time to intra-arterial but not to intravenous thrombolysis, higher mortality rate, and smaller gain in functional status as measured by the modified Barthel Index at 3 months. The degree of emergency department "busyness" also did not influence tissue-type plasminogen activator treatment times. Presentation during a nursing shift change, a time of transition of care, did not delay thrombolytic use in eligible patients with acute ischemic stroke. Presentation with acute ischemic stroke at night did result in delays of care for patients undergoing interventional therapies.

    To evaluate the feasibility and safety of utilizing a commercially available virtual reality gaming system as a treatment intervention for balance training. A randomized controlled trial in which assessment and analysis were blinded. An inpatient rehabilitation facility. Interventions included balance-based physical therapy using a Nintendo Wii, as monitored by a physical therapist, and receipt of one-on-one balance-based physical therapy using standard physical therapy modalities available for use in the therapy gym. Participants in the standard physical therapy group were found to have slightly higher enjoyment at mid-intervention, while those receiving the virtual reality-based balance intervention were found to have higher enjoyment at study completion. Both groups demonstrated improved static and dynamic balance over the course of the study, with no significant differences between groups. Correlational analyses suggest a relationship exists between Wii balance board game scores and BBS scores for measures taken beyond the baseline assessment. This study provides a modest level of evidence to support using commercially available VR gaming systems for the treatment of balance deficits in patients with a primary diagnosis of TBI receiving inpatient rehabilitation. Additional research of these types of interventions for the treatment of balance deficits is warranted.

    The Individuals with Disabilities Education Act (Part C) authorizes states to establish systems to provide early intervention services (e.g., therapy) for children at risk, with the incentive of federal financial support. This study examines family and neighborhood characteristics associated with currently utilizing physical, occupational, or speech therapy among very low birthweight (VLBW) 2-year-old children who meet Wisconsin eligibility requirements for early intervention services (EI) due to developmental delay. This cross-sectional analysis used data from the Newborn Lung Project, a regional cohort study of VLBW infants hospitalized in Wisconsin's newborn intensive care units during 2003-2004. We included the 176 children who were age two at follow-up, and met Wisconsin state eligibility requirements for EI based on developmental delay. Exact logistic regression was used to describe child and neighborhood socio-demographic correlates of parent-reported receipt of therapy. Among VLBW children with developmental delay, currently utilizing therapy was higher among children with Medicaid (aOR = 5.3, 95% CI: 1.3, 28.3) and concomitant developmental disability (aOR = 5.2, 95% CI: 2.1, 13.3) and lower for those living in a socially more disadvantaged neighborhood (aOR=0.48, 95% CI: 0.21, 0.98, per tertile). Among a sample of VLBW 2-year olds with developmental delays who are EI-eligible in WI, 4 out of 5 were currently receiving therapy, per parent report. Participation in Medicaid positively influences therapy utilization. Children with developmental difficulties who live in socially disadvantaged neighborhoods are at highest risk for not receiving therapy.

    Disulfiram is widely used in the treatment of chronic alcoholism. Adverse drug reactions with fatal outcome following disulfiram therapy are infrequent, and hepatic failure accounts for most of them. Since disulfiram is a cytochrome P450 (CYP450) enzyme system inhibitor, numerous interactions with several drugs metabolized in the liver have been reported. Like disulfiram, clarithromycin inhibits a CYP450 isoenzyme, but, despite its widespread use for the treatment of respiratory tract infections, no interactions with disulfiram have been described as yet. We report a case of fatal toxic epidermal necrolysis (Lyell disease) and fulminant hepatitis shortly after starting treatment with clarithromycin in a patient who was receiving disulfiram. This is the first case of such a severe dermatosis in a patient receiving either disulfiram or clarithromycin therapy. The temporal relationship between drug administration and clinical symptoms in this case suggests a probable interaction between the 2 drugs.

    Episodic use of antiretroviral therapy guided by CD4+ cell counts is inferior to continuous antiretroviral therapy. To determine whether reinitiating continuous antiretroviral therapy in patients who received episodic treatment reduces excess risk for opportunistic disease or death. Randomized, controlled trial. Sites in 33 countries. 5472 HIV-infected individuals with CD4(+) cell counts greater than 0.350 x 10(9) cells/L enrolled from January 2002 to January 2006. Episodic or continuous antiretroviral therapy initially, followed by continuous therapy in participants previously assigned to episodic treatment. Opportunistic disease or death was the primary outcome. Eighteen months after the recommendation to reinitiate continuous therapy, mean CD4+ cell counts were 0.152 x 10(9) cells/L (95% CI, 0.136 to 0.167 x 10(9) cells/L) less in participants previously assigned to episodic treatment (P < 0.001). The proportion of follow-up time spent with CD4+ cell counts of 0.500 x 10(9) cells/L or more and HIV RNA levels of 400 copies/mL or less was 29% for participants initially assigned to episodic therapy and 66% for those assigned to continuous therapy. Participants who reinitiated continuous therapy experienced rapid suppression of HIV RNA levels (89.7% with HIV RNA levels < or =400 copies/mL after 6 months), but CD4+ cell counts after 6 months remained 0.140 x 10(9) cells/L below baseline. The hazard ratio (episodic versus continuous treatment) for opportunistic disease or death decreased after the recommendation to reinitiate continuous therapy (from 2.5 [CI, 1.8 to 3.5] to 1.4 [CI, 1.0 to 2.0]; P = 0.033 for difference). The residual excess risk was attributable to failure to reinitiate therapy by some participants and slow recovery of CD4+ cell counts for those who reinitiated therapy. Follow-up was too short to assess the full effect of switching from episodic to continuous antiretroviral therapy. Reinitiating continuous antiretroviral therapy in patients

    Purpose Few studies to date have evaluated factors associated with the development of radiation pneumonitis (RP) in patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), especially in patients treated with contemporary radiation techniques. These patients represent a unique group owing to the often large radiation target volumes within the mediastinum and to the potential to receive several lines of chemotherapy that add to pulmonary toxicity for relapsed or refractory disease. Our objective was to determine the incidence and clinical and dosimetric risk factors associated with RP in lymphoma patients treated with intensity modulated radiation therapy (IMRT) at a single institution. Methods We retrospectively reviewed clinical charts and radiation records of 150 consecutive patients who received mediastinal IMRT for HL and NHL from 2009 through 2013. Clinical and dosimetric predictors associated with RP per the Radiation Therapy Oncology Group (RTOG) acute toxicity criteria were identified in univariate analysis using the Pearson χ2 test and logistic multivariate regression. Results Mediastinal radiation was administered as consolidation therapy in 110 patients with newly diagnosed HL or NHL and in 40 patients with relapsed or refractory disease. The overall incidence of RP (RTOG grade 1–3) was 14% in the entire cohort. Risk of RP was increased for patients who received radiation for relapsed or refractory disease (25%) versus those who received consolidation (10%, P=0.019). Several dosimetric parameters predicted RP, including mean lung dose (MLD) >13.5 Gy, V20 >30%, V15 >35%, V10 >40% and V5>55%. The likelihood ratio (LR) χ2 value was highest for V5< 55% (LR χ2=19.37). Conclusions In using IMRT to treat mediastinal lymphoma, all dosimetric parameters predicted RP, although small doses to large volumes of lung had the greatest influence.

    The interferon system was studied in women with genital papillomavirus infection. In most patients the interferon system was activated, while the ability of lymphocytes to respond to inductors decreased. Laserotherapy and immunomodulatory therapy with larifan, ridostin, and viferon for 1 month normalized blood interferon concentration (39.4% patients) and interferon-gamma production by lymphocytes in response to inductors (87.9% patients). After laser monotherapy these parameters returned to normal only in 13.2 and 7.6% patients, respectively. Correlation and regression analyses showed that changes in the interferon system were synchronized after immunomodulatory therapy. These data indicate that immunomodulatory therapy produces a complex effect on the interferon system. Measurements of blood interferon level can be used to predict the effect of further treatment with interferon-gamma inductors.

    Background The practice of minimal handling is recommended for preterm infants (PTIs). However, few studies have investigated the effects of this practice among these infants or the time needed to ensure greater physiological stability, especially after exogenous surfactant treatments. Objective The current study compared the effects of two protocols of minimal handling on the physiological variables of PTIs after surfactant therapy. Method An exploratory prospective observational study was performed with 40 PTIs weighing less than 1,500 g. The infants were divided into two groups and monitored for 72 hours. One group received the standard minimal handling procedure during the first 12 hours after surfactant therapy; the other group (i.e., the modified group) received minimal handling within 72 hours after surfactant therapy. Infant heart rate (HR), oxygen saturation, body temperature, and the adverse events associated with changes to these variables were monitored every 10 minutes. Results Significant between-group differences were not found with regard to the occurrence of the adverse events associated with physiological changes (p>0.05). Conclusion The practice of minimal handling among very low birth weight infants did not alter their physiological stability when performed either 12 or 72 hours after surfactant therapy.

    Hepatitis C infection and its treatment have been associated with extrahepatic manifestations, including different skin conditions. Over the past decades, a greater number of drugs have been implicated as triggers for drug-induced subacute cutaneous lupus erythematosus. We report a case of a 42-year-old Hispanic man who developed a forehead violaceous rash during treatment with pegylated interferon alpha-2a as part of his therapy against hepatitis C infection that subsequently resulted to be subacute cutaneous lupus erythematosus. The skin lesion improved with discontinuation of medication and some topic therapy.

    Fluconazole is a renally-eliminated antifungal commonly used to treat Candida species infections. In critically-ill patients receiving prolonged intermittent renal replacement therapy (PIRRT), limited pharmacokinetic (PK) data are available to guide fluconazole dosing. We used previously-published fluconazole clearance data and PK data of critically-ill patients with acute kidney injury to develop a PK model with the goal of determining a therapeutic dosing regimen for critically-ill patients receiving PIRRT. Monte Carlo simulations were performed to create a virtual cohort of patients receiving different fluconazole dosing regimens. Plasma drug concentration-time profiles were evaluated on the probability of attaining a mean 24-hour area under the drug concentration-time curve to minimum inhibitory concentration ratio (AUC24h : MIC) of 100 during the initial 48 hours of antifungal therapy. At the susceptibility breakpoint of Candida albicans (2 mg/L), 93 - 96% of simulated subjects receiving PIRRT attained the pharmacodynamic target with a fluconazole 800-mg loading dose plus 400 mg twice daily (q12h or pre and post PIRRT) regimen. Monte Carlo simulations of a PK model of PIRRT provided a basis for the development of an informed fluconazole dosing recommendation when PK data was limited. This finding should be validated in the clinical setting.

    AIM: To compare the incidence of early portal or splenic vein thrombosis (PSVT) in patients treated with irregular and regular anticoagulantion after splenectomy with gastroesophageal devascularization. METHODS: We retrospectively analyzed 301 patients who underwent splenectomy with gastroesophageal devascularization for portal hypertension due to cirrhosis between April 2004 and July 2010. Patients were categorized into group A with irregular anticoagulation and group B with regular anticoagulation, respectively. Group A (153 patients) received anticoagulant monotherapy for an undesignated time period or with aspirin or warfarin without low-molecular-weight heparin (LMWH) irregularly. Group B (148 patients) received subcutaneous injection of LMWH routinely within the first 5 d after surgery, followed by oral warfarin and aspirin for one month regularly. The target prothrombin time/international normalized ratio (PT/INR) was 1.25-1.50. Platelet and PT/INR were monitored. Color Doppler imaging was performed to monitor PSVT as well as the effectiveness of thrombolytic therapy. RESULTS: The patients’ data were collected and analyzed retrospectively. Among the patients, 94 developed early postoperative mural PSVT, including 63 patients in group A (63/153, 41.17%) and 31 patients in group B (31/148, 20.94%). There were 50 (32.67%) patients in group A and 27 (18.24%) in group B with mural PSVT in the main trunk of portal vein. After the administration of thrombolytic, anticoagulant and anti-aggregation therapy, complete or partial thrombus dissolution achieved in 50 (79.37%) in group A and 26 (83.87%) in group B. CONCLUSION: Regular anticoagulation therapy can reduce the incidence of PSVT in patients who undergo splenectomy with gastroesophageal devascularization, and regular anticoagulant therapy is safer and more effective than irregular anticoagulant therapy. Early and timely thrombolytic therapy is imperative and feasible for the prevention of PSVT. PMID:22807615

    This review will describe advances in detection and results of monitoring persistent viremia in patients on long-term suppressive therapy. In addition, the review explores the usefulness of these methods in determining the effectiveness of new HIV-1 eradication strategies in purging persistent HIV-1 reservoirs. Quantification of plasma HIV-1 RNA levels remains essential for determining the success of combination antiretroviral therapy (cART) in treated patients. Recently, several new platforms with improved sensitivity for quantifying HIV-1 RNA have been developed and the application of these assays has revealed that low-level viremia persists in patients on suppressive therapy. In addition, new technological advances such as digital PCR have been proposed to increase the sensitivity of measuring and characterizing persistent HIV-1 viremia. The application of these assays will be important in determining the effectiveness of future HIV-1 eradication strategies. The level of HIV-1 RNA in patient plasma remains an important marker for determining the success of cART. New sensitive assays have found that HIV-1 persists in the plasma of patients on suppressive therapy that may have implications for the clinical management of this disease and strategies for eliminating HIV-1 infection.

    The oral hormonal agent anastrozole improves clinical outcomes for women with breast cancer, but women have difficulty taking it for the five-year course. The unique medication-taking experiences related to self-management of anastrozole therapy for women with early stage breast cancer are not known. Our purpose was to describe the medication-taking experiences for postmenopausal women with early stage breast cancer who were prescribed a course of anastrozole therapy. Twelve women aged 58 to 67 years, midway through therapy, participated in audio-recorded interviews. Women's medication-taking experiences involved a belief in their importance and an imperative to take anastrozole. We found that women's side effect experiences, particularly menopausal symptoms, were significant, but only one woman stopped anastrozole due to side effects. Medication-taking included routinization interconnected with remembering/forgetting and a storage strategy. Some women noted a mutual medication-taking experience with their spouse, but most felt taking anastrozole was something they had to do alone. Our results provide insight into the way some women with early stage breast cancer manage their hormonal therapy at approximately the midpoint of treatment. Next steps should include examinations of patient-provider communication, potential medication-taking differences between pre- and postmenopausal women, and the effects of medication-taking on clinical outcomes.

    On rare occasions, patients infected with human immunodeficiency virus (HIV) can develop a disorder similar to chronic progressive external ophthalmoplegia (CPEO) while undergoing long-term treatment with antiretroviral therapy. Orbital imaging may help explain the pathogenesis of this abnormality. In this case series, 5 adult patients who presented with a CPEO-like disorder after more than 10 years of antiretroviral therapy and who underwent T1-weighted high-resolution magnetic resonance imaging (MRI) of the orbits and brain were retrospectively identified. Patients also were screened for acetylcholine receptor antibody levels. All patients had bilateral external ophthalmoplegia and blepharoptosis. Acetylcholine receptor antibody titers were not increased. Brain MRI was unremarkable. Orbital MRI showed patchy bright signal inside the extraocular muscles that had conserved volume. Patients with HIV under long-term antiretroviral therapy may develop functional abnormalities of extraocular muscles that are structurally normal in size, that is, changes are similar to those observed in the orbital MRIs of patients with CPEO. This constellation of signs and symptoms suggests a possible role of HIV disease or antiretroviral therapy in the CPEO-like syndrome observed in some HIV-infected individuals.

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin S<50%) who developed symptomatic anemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    The differential impact of the number of prior lines of therapy and the setting of prior therapy (perioperative or metastatic) is unclear in advanced urothelial carcinoma. Ten phase II trials of salvage chemotherapy, biologic agent therapy, or both, enrolling 731 patients, were available. Data on the number of prior lines of therapy and the setting of prior therapy were required in addition to known previously recognized prognostic factors: time from prior chemotherapy, hemoglobin level, performance status, and liver metastasis status. Cox proportional hazards regression was used to evaluate the association of the number of prior lines and prior perioperative therapy with overall survival (OS) as the primary clinical endpoint. Trial was a stratification factor. A total of 711 patients were evaluable. The overall median progression-free survival and OS were 2.7 and 6.8 months, respectively. The number of prior lines was 1 in 559 patients (78.6%), 2 in 111 (15.6%), 3 in 29 (4.1%), 4 in 10 (1.4%), and 5 in 2 (0.3%). Prior perioperative chemotherapy was given to 277 (39.1%) and chemotherapy for metastatic disease to 454 (64.1%). The number of prior lines was not independently associated with OS (hazard ratio, 0.99; 95% CI, 0.86-1.14). Prior perioperative chemotherapy was a favorable factor for OS on univariate but not multivariate analysis. The number of prior lines of therapy and prior perioperative chemotherapy were not independently prognostic in patients with urothelial carcinoma receiving salvage therapy. Adoption of these data in salvage therapy trials should enhance accrual, the interpretability of results, and drug development. Copyright © 2015 Elsevier Inc. All rights reserved.

    It has been estimated that more than $8 billion is spent annually on the management of breast cancer in the United States. The taxane chemotherapeutic agents are cornerstones in the treatment of breast cancer, yet no study has assessed whether the choice of a taxane affects the economic outcomes of metastatic breast cancer treatment. To determine if differences exist in the medical cost of care in patients receiving taxane-based chemotherapy for metastatic breast cancer, and to compare the use of ancillary medications (for neutropenia, anemia, and nausea and vomiting) and their associated costs among taxanes. We identified women with metastatic breast cancer based on diagnosis codes and the women's previous adjuvant chemotherapeutic regimens. Paid medical insurance claims were captured for the 24-month study period, from January 1, 2006, through December 31, 2007. The groups were determined according to the specific taxane administered. Total medical costs were captured from the date of first taxane administration to the end of data availability. Outpatient pharmacy costs were not available. A multivariate analysis was used to evaluate the total medical costs in each group. Median total medical costs per patient per month during the study period were adjusted using a multiple regression analysis. Utilization and cost of medications administered in the office or hospital for chemotherapy-induced adverse effects were captured and adjusted with Tobit models. Of the 2245 study participants, 1035 received docetaxel, 997 received generic paclitaxel, and 213 received nab-paclitaxel. On average, patients in the nab-paclitaxel group received more doses (9.6) than those in the generic paclitaxel (6.0) or docetaxel (4.8) groups. The multivariate analysis was robust, explaining 72% of the variability in total medical costs across the 3 taxane groups. Median per-patient per-month total medical costs for study participants were within approximately $800 of each other among the

    To compare psychological and pain-related characteristics of patients with chronic pain and patients with refractory angina pectoris who had been treated with spinal cord stimulation (SCS) therapy. Twenty-four patients receiving SCS therapy were interviewed. Four psychological variables were assessed using standardised questionnaires for pain catastrophising, health locus of control, anxiety sensitivity, and self-efficacy. Patients also completed the revised version of the Short-Form McGill Pain Questionnaire, the Short-Form Health Survey, and self-reported measures of global perceived effect, pain, functionality, and satisfaction with SCS therapy. Most patients reported improvements in pain, functionality, and improvement overall. Some health locus of control dimensions were significantly higher for the angina group than the chronic pain group, and chronic angina patients reported significantly lower levels of intermittent pain. Virtually all patients reported being satisfied with SCS therapy. Most self-rated psychological and pain-related characteristics were no different between the two groups, which gives some support to the view that refractory angina is a form of chronic pain. The results also add to evidence supporting the use of SCS therapy for refractory angina pectoris; however, differences observed on a few variables may indicate points of focus for the assessment and treatment of such patients.

    Dialyzable leukocyte extract (DLE) is one of the immunological agents used as an adjuvant in cancer therapy; it has been associated with improved quality of life during cancer chemotherapy. Based on these previous findings and on the observed clinical benefits attributed to DLE in other types of cancer, we investigated its clinical and immunological effects as a therapy adjuvant on breast cancer patients who received only chemotherapy, as compared to patients administered bovine DLE (bDLE) as an adjuvant. This study included 43 breast cancer patients who were about to begin chemotherapy. This group was divided as follows: 25 received chemotherapy and bDLE as an adjuvant therapy, and 18 received only chemotherapy without the adjuvant. All patient clinical and immunological responses were monitored. Among patients in the group that received bDLE as adjuvant, 60% showed a complete response, 32% showed a partial response and 8% did not respond. By contrast, in the group without the adjuvant, 39% showed a complete response, 50% displayed a partial response and 11% were non-responders. In addition, bDLE treatment in combination with chemotherapy resulted in the enhancement of the Karnofsky performance scale during chemotherapy. Even though patients underwent several cycles of chemotherapy without bDLE, the lymphocyte population dropped to below the reference value. On the other hand, in patients with bDLE as adjuvant, the CD4(+) and CD8(+) lymphocytes and the B lymphocytes were maintained within the median range of the reference value. The number of natural killer cells also increased after chemotherapy treatment with bDLE as an adjuvant. In conclusion, bDLE treatment contributes to significant immunological recovery in patients that have undergone heavy chemotherapy, increasing the clinical response and quality of life during chemotherapy.

    After informed consent, blood samples were obtained to measure leptin, FSH, LH, insulin, 17-beta-estradiol, and IGF-1. No differences in serum leptin was observed between the women on Tibolone (8.1 +/- 4.2 ng/mL) and the control group (7.4 +/- 3.7 ng/mL). Women on Tibolone had lower insulin levels (16.4 +/- 1.8) than women without therapy (19.4 +/- 1.3 mU/mL) (p < 0.05). On the contrary IGF-I levels were elevated (150.0 +/- 16.4) as compared with those in non-treated women (121.0 +/- 13.4 ng/mL) (p < 0.05). Body weight was similar between the two groups. From these data it is concluded that Tibolone, as replacement therapy, does not increase circulating leptin and seems to have no effect on body weight.

    Anti-TNF-alpha agents are increasingly used in rheumatoid arthritis (RA) treatment and that is known to increase the risk of tuberculosis (TB) reactivation. Adenosine deaminase (ADA) levels are shown to increase to high levels in TB patients. Our aim is to investigate the serum ADA levels in RA patients being treated with anti-TNF-alpha and to compare the results with the patients on DMARD therapy. The study groups comprised of 56 RA patients (45 female, mean age 49) who were treated either with two or three DMARDs, 32 RA patients with anti-TNF-alpha treatment (26 female, mean age 46) and 20 healthy controls (10 female, mean age 48). All patients fulfilled the 1987 ACR criteria for RA. DAS28 score was calculated for all subjects. When compared to healthy controls, ADA levels were measured statistically higher both in patient groups (P = 0.046, 0.002). ADA levels in anti-TNF-alpha group were similar to conventional therapy (11.3 +/- 2.7, 10.9 +/- 4.01; P = 0.76). PPD was positive in 17 RA patients in the anti-TNF-alpha treatment group (%53). The ADA levels were found to be similar in the anti-TNF-alpha group when compared according to the PPD positivity (positive, 12.4 +/- 3.7; negative, 10.5 +/- 2.1; P = 0.02). No correlation was found between the ADA levels and age, disease duration, ESR, CRP, DAS 28 and HAQ score. In this study, we observed that RA patients at remission taking DMARD or anti-TNF-alpha therapy have similar levels of serum ADA. Although serum ADA levels during TB infection increase much higher, in our study, ADA levels of all RA patients were lower than 15 IU/L. Elevated ADA levels may be a clue for diagnosis of TB in patients who were on anti-TNF-alpha therapy.

    BACKGROUND The dermatologic adverse events (AEs) of various molecularly targeted therapies are well-described in adult cancer patients. Little has been reported on the incidence and clinical presentation of such AEs in pediatric patients with cancer. To address this gap, we analyzed the dermatologic AEs reported across clinical trials of targeted anticancer therapies in pediatric patients. METHODS We conducted an electronic literature search (PubMed, American Society of Clinical Oncology annual meetings’ abstracts, ClinicalTrials.gov, NCI’s Pediatric Oncology Branch webpage) to identify clinical trials involving targeted anticancer therapies that reported dermatologic AEs in their safety data. Studies were limited to the pediatric population, monotherapy trials (oncology), and English language publications. RESULTS Pooled data from 19 clinical studies investigating 11 targeted anticancer agents (alemtuzumab, rituximab, imatinib, dasatinib, erlotinib, vandetanib, sorafenib, cabozantinib, pazopanib, everolimus, and temsirolimus) were analyzed. The most frequently encountered dermatologic AEs were rash (127/660; 19%), xerosis (18/100; 18%), mucositis (68/402; 17%) and pruritus (12/169; 7%). Other AEs included pigmentary abnormalities of the skin/hair (13%), hair disorders (trichomegaly, hypertrichosis, alopecia and madarosis; 14%), urticaria (7%), palmoplantar erythrodysesthesia (7%), erythema, acne, purpura, skin fissures, other ‘unknown skin changes’, exanthem, infection, flushing, telangiectasia, and photosensitivity. CONCLUSION This study describes the dermatologic manifestations of targeted anticancer therapy-related AEs in the pediatric population. Since these AEs are often associated with significant morbidity, it is imperative that pediatric oncologists be familiar with their recognition and management, to avoid unnecessary dose modifications and/or termination, and to prevent impairments in patients’ quality of life.

Other AEs included pigmentary abnormalities of the skin/hair (13%), hair disorders (trichomegaly, hypertrichosis, alopecia, and madarosis; 14%), urticaria (7%), palmoplantar erythrodysesthesia (7%), erythema, acne, purpura, skin fissures, other 'unknown skin changes', exanthem, infection, flushing, telangiectasia, and photosensitivity. This study describes the dermatologic manifestations of targeted anticancer therapy-related AEs in the pediatric population. Since these AEs are often associated with significant morbidity, it is imperative that pediatric oncologists be familiar with their recognition and management, to avoid unnecessary dose modifications and/or termination, and to prevent impairments in patients' quality of life. © 2015 Wiley Periodicals, Inc.

    To compare a 12-week nontraditional exercise Nia program practiced at home to usual care on fatigue, quality of life (QOL), aerobic capacity, and shoulder flexibility in women with breast cancer undergoing radiation therapy. Randomized clinical trial. Large community-based hospital in the midwestern United States. 41 women with stage I, II, or III breast cancer starting radiation therapy. 22 women were randomized to the Nia group and 19 to the usual care group. Those in the Nia group were instructed to practice Nia 20-60 minutes three times per week for 12 weeks. Those in the usual care group were instructed to continue normal activities. Fatigue, QOL, aerobic capacity, and shoulder flexibility. Controlling for baseline scores, change over time between groups was significantly different for the women who practiced Nia at least 13 times during the 12-week period; those in the Nia intervention reported significantly less fatigue between weeks 6 and 12, as compared to control group (p = 0.05). No statistical differences in QOL, aerobic capacity, or shoulder flexibility were found, but trends favoring Nia were identified. For women undergoing radiation therapy for breast cancer, Nia can help relieve fatigue. Additional research in arm and shoulder mobility and preservation also may be beneficial. Oncology nurses are in a unique position to offer suggestions to help manage fatigue, and Nia could be considered as part of a cancer survivorship program. Exercise is beneficial for women with breast cancer, and interest is growing in nontraditional exercise options. Nia can benefit women with breast cancer undergoing radiation therapy.

    Fusion inhibitors are novel antiretroviral agents, administered as subcutaneous injections, approved for use in treatment-experienced HIV-infected patients. HIV-infected patients are at increased risk for Staphylococcus aureus colonization, specifically with methicillin-resistant S aureus (MRSA), and subsequent systemic infection. We present the cases of 2 patients without a history of MRSA infection in whom a series of severe S aureus infections developed after fusion inhibitor therapy.

    Background The aim of this study was to evaluate the antiemetic effect of aprepitant and to determine how to provide triple combination therapy (aprepitant/azasetron/dexamethasone) to women receiving paclitaxel/carboplatin moderately emetogenic chemotherapy (MEC). Material/Methods The current study was a prospective study of 163 women with gynecologic cancers. We compared the digestive symptoms scores (nausea, vomiting, appetite loss, and dietary intake) of 37 women with ovarian cancers before and after aprepitant administration. We also compared these symptoms in women who underwent 193 cycles of triple combination therapy with symptoms of women who underwent 226 cycles of double combination therapy. For triple combination therapy, azasetron, dexamethasone (reduced dose: 40% of 20 mg), and aprepitant (125 mg) were administered on Day 1, followed by only aprepitant (80 mg) administration on Days 2 and Day 3. Results In 37 women with ovarian cancer, three symptoms, nausea, appetite loss, and dietary intake, were significantly improved by primarily adding aprepitant to double combination therapy in the delayed phase of MEC. Upon comparing their digestive symptoms in all cycles, however, these three symptoms were not significantly different in the delayed phase. Furthermore, all four symptoms in all cycles were worse following triple combination therapy than following double combination therapy in the acute phase (p<0.02). The control of digestive symptoms was generally insufficient without the administration of dexamethasone. Conclusions Primary aprepitant as an addition to MEC demonstrated efficacy in improving digestive symptoms in the delayed phase. However, its effect may decrease with repeated use. To improve the antiemetic effect, the dose reduction of dexamethasone should be restricted on Day 1 and dexamethasone should be used throughout the delayed phase as well. PMID:28198358

    The aim of this study was to evaluate posttreatment changes of individuals with a diagnosis of gambling disorder (GD) treated with group cognitive behavioral therapy (CBT), to assess the potential moderator effect of sex on CBT outcome, and to explore the best predictors of posttreatment changes, relapse, and dropout rates. A cohort design was applied with a prospective follow-up. The sample comprised 440 patients and the CBT intervention consisted of 16 weekly outpatient group sessions and a 3-month follow-up period. Patients showed significant improvements in both the level of psychopathology and the severity of the gambling behavior. High self-transcendence and the involvement of the spouse or partner in the therapy predicted a higher risk of relapse. Younger age and low education predicted a higher risk of dropout. Many patients with GD can be treated with strategies to improve self-control and emotional regulation, but other techniques should be incorporated to address the individual characteristics of each patient. This is particularly important in group therapy, in which the same treatment is applied to several patients simultaneously. The involvement of a family member needs to be carefully considered since it may have a negative effect on the response to treatment if not adequately managed.

    Persons undergoing physical therapy home services often have difficulty with mobility and gait. The purpose of this study was to determine whether there was a relationship between gait and a rating of cognitive functioning in persons undergoing home-care physical therapy services. Patients over the age of 65 (n = 11,601) seen by a home-care agency between 2007 and 2008 were included in the retrospective analysis, and 10,953 (mean +/- standard deviation age 83.2 +/- 7.1; 31%) met the criteria of being able to ambulate independently or with an assistive device. All patients attempted to perform the modified Clinical Test of Sensory Integration and Balance plus either the Performance Oriented Measurement Assessment (POMA) or the Dynamic Gait Index (DGI). Mental function was scored as part of the Outcome and Assessment Information Set. A multivariate model with adjustment for age and sex identified gait performance as measured by the DGI to be independently associated with the likelihood that a patient required cognitive prompting (p = 0.03). Both the DGI and POMA scores were independently associated with requiring assistance/dependence with cognitive tasks. There was a strong relationship between cognition and gait performance in persons undergoing physical therapy interventions in the home. Changes in gait may be related to cognitive decline.

    Purpose: Reduction of respiratory motion is desirable to reduce the volume of normal tissues irradiated, to improve concordance of planned and delivered doses, and to improve image guided radiation therapy (IGRT). We hypothesized that pretreatment lorazepam would lead to a measurable reduction of liver motion. Methods and Materials: Thirty-three patients receiving upper abdominal IGRT were recruited to a double-blinded randomized controlled crossover trial. Patients were randomized to 1 of 2 study arms: arm 1 received lorazepam 2 mg by mouth on day 1, followed by placebo 4 to 8 days later; arm 2 received placebo on day 1, followed by lorazepam 4 to 8 days later. After tablet ingestion and daily radiation therapy, amplitude of liver motion was measured on both study days. The primary outcomes were reduction in craniocaudal (CC) liver motion using 4-dimensional kV cone beam computed tomography (CBCT) and the proportion of patients with liver motion ≤5 mm. Secondary endpoints included motion measured with cine magnetic resonance imaging and kV fluoroscopy. Results: Mean relative and absolute reduction in CC amplitude with lorazepam was 21% and 2.5 mm respectively (95% confidence interval [CI] 1.1-3.9, P=.001), as assessed with CBCT. Reduction in CC amplitude to ≤5 mm residual liver motion was seen in 13% (95% CI 1%-25%) of patients receiving lorazepam (vs 10% receiving placebo, P=NS); 65% (95% CI 48%-81%) had reduction in residual CC liver motion to ≤10 mm (vs 52% with placebo, P=NS). Patients with large respiratory movement and patients who took lorazepam ≥60 minutes before imaging had greater reductions in liver CC motion. Mean reductions in liver CC amplitude on magnetic resonance imaging and fluoroscopy were nonsignificant. Conclusions: Lorazepam reduces liver motion in the CC direction; however, average magnitude of reduction is small, and most patients have residual motion >5 mm.

    Purpose: Few studies to date have evaluated factors associated with the development of radiation pneumonitis (RP) in patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL), especially in patients treated with contemporary radiation techniques. These patients represent a unique group owing to the often large radiation target volumes within the mediastinum and to the potential to receive several lines of chemotherapy that add to pulmonary toxicity for relapsed or refractory disease. Our objective was to determine the incidence and clinical and dosimetric risk factors associated with RP in lymphoma patients treated with intensity modulated radiation therapy (IMRT) at a single institution. Methods and Materials: We retrospectively reviewed clinical charts and radiation records of 150 consecutive patients who received mediastinal IMRT for HL and NHL from 2009 through 2013. Clinical and dosimetric predictors associated with RP according to Radiation Therapy Oncology Group (RTOG) acute toxicity criteria were identified in univariate analysis using the Pearson χ{sup 2} test and logistic multivariate regression. Results: Mediastinal radiation was administered as consolidation therapy in 110 patients with newly diagnosed HL or NHL and in 40 patients with relapsed or refractory disease. The overall incidence of RP (RTOG grades 1-3) was 14% in the entire cohort. Risk of RP was increased for patients who received radiation for relapsed or refractory disease (25%) versus those who received consolidation therapy (10%, P=.019). Several dosimetric parameters predicted RP, including mean lung dose of >13.5 Gy, V{sub 20} of >30%, V{sub 15} of >35%, V{sub 10} of >40%, and V{sub 5} of >55%. The likelihood ratio χ{sup 2} value was highest for V{sub 5} >55% (χ{sup 2} = 19.37). Conclusions: In using IMRT to treat mediastinal lymphoma, all dosimetric parameters predicted RP, although small doses to large volumes of lung had the greatest influence. Patients with relapsed

    Infectious diseases and impaired renal function often occur in critically ill patients, and delaying the start of appropriate empiric antimicrobial therapy or starting inappropriate therapy has been associated with poor outcomes. Our primary objective was to critically review and discuss the influence of chronic kidney disease (CKD) and acute kidney injury (AKI) on the clinical pharmacokinetic and pharmacodynamic properties of antimicrobial agents. The effect of continuous renal replacement therapies (CRRTs) and intermittent hemodialysis (IHD) on drug disposition in these two populations was also evaluated. Finally, proposed dosing strategies for selected antimicrobials in critically ill adult patients as well as those receiving CRRT or IHD have been compiled. We conducted a PubMed search (January 1980-March 2008) to identify all English-language literature published in which dosing recommendations were proposed for antimicrobials commonly used in critically ill patients, including those receiving CRRT or IHD. All pertinent reviews, selected studies, and associated references were evaluated to ensure their relevance. Forty antimicrobial, antifungal, and antiviral agents commonly used in critically ill patients were included for review. Dosage recommendations were synthesized from the 42 reviewed articles and peer-reviewed, evidence-based clinical drug databases to generate initial guidance for the determination of antimicrobial dosing strategies for critically ill adults. Because of the evolving process of critical illness, whether in patients with AKI or in those with CKD, prospective adaptation of these initial dosing recommendations to meet the needs of each individual patient will often rely on prospectively collected clinical and laboratory data.

  12. Sexual adjustment of male alcoholics: changes from before to after receiving alcoholism counseling with and without marital therapy.

    Married male alcoholics (N = 36), who had recently begun individual outpatient alcoholism counseling, were randomly assigned to a no-marital-treatment control group or to 10 weekly sessions of either a behavioral marital therapy (BMT) or an interactional couples therapy group. Impotence decreased from before to after counseling irrespective of whether the alcoholic patients received additional marital therapy. Husbands who received BMT reported increased frequency of wives' orgasm during intercourse and greater increases in satisfaction with the privacy and context of their sexual activities than did couples in the other two treatment groups. These findings support a biopsychosocial formulation of alcoholics' sexual problems that implicates the physical effects of acute and chronic alcohol intake as most relevant to the elevated rates of impotence and marital conflict as a major contributing factor to most sexual problems of alcoholics. The improvement observed in sexual adjustment was rather limited. Despite the improvements in impotence, the alcoholics still experienced over twice the rate of impotence reported by demographically similar nonalcoholics. In terms of sexual satisfaction, BMT produced only modest gains as viewed by husbands and no gains from the wives' perspective. Perhaps sexual adjustment is one of the last areas of the alcoholic's marriage to improve after treatment. The limited time frame of the present study may have precluded observing further improvements in sexual adjustment that would emerge later after a longer period of recovery.

    Invasive candidiasis has increased as nosocomial infection recently in cancer patients who receive systemic chemotherapy, and the timely risk assessment for developing such specific infection is crucial. Especially in those concomitantly with hypopituitarism, febrile neutropenia with candidiasis can cause severe stress and lead potentially to sudden fatal outcome when the temporal steroid coverage for the adrenal insufficiency is not fully administered. We report a 72-year-old male case diagnosed as non-small-cell lung cancer, Stage IIIA. He had received a steroid replacement therapy for the prior history of hypophysectomy due to pituitary adenoma with hydrocortisone of 3.3 mg/day, equivalent to prednisolone of 0.8 mg/day. This very small dosage of steroid was hardly supposed to weaken his immune system, but rather potentially led to an inappropriate supplementation of his adrenal function, assuming that the serum sodium and chlorine levels decreased. On Day 6 of second cycle of chemotherapy with carboplatin and paclitaxel, he developed sudden febrile neutropenia, septic shock and ileus, leading to death. After his death, the venous blood culture on Day 7 detected Candida albicans. Autopsy findings showed a massive necrotizing enterocolitis with extensive Candida invasion into submucous tissue. In conclusion, this case may suggest that (i) immediate initiation of antifungal therapy soon after the careful risk assessment of Candida infection and (ii) adequate administration of both basal steroid replacement therapy and temporal steroid coverage for febrile neutropenia might have improved his fatal outcome.

    The impact of continuous renal replacement therapy (CRRT) on drug removal is complicated; pharmacist dosing adjustment for these patients may be advantageous. This study aims to describe the development and implementation of pharmacist dosing adjustment for critically ill patients receiving CRRT and to examine the effectiveness of pharmacist interventions. A comparative study was conducted in an intensive care unit (ICU) of a university-affiliated hospital. Patients receiving CRRT in the intervention group received specialized pharmacy dosing service from pharmacists, whereas patients in the no-intervention group received routine medical care without pharmacist involvement. The two phases were compared to evaluate the outcome of pharmacist dosing adjustment. The pharmacist carried out 233 dosing adjustment recommendations for patients receiving CRRT, and 212 (90.98%) of the recommendations were well accepted by the physicians. Changes in CRRT-related variables (n=144, 61.81%) were the most common risk factors for dosing errors, whereas antibiotics (n=168, 72.10%) were the medications most commonly associated with dosing errors. Pharmacist dosing adjustment resulted in a US$2,345.98 ICU cost savings per critically ill patient receiving CRRT. Suspected adverse drug events in the intervention group were significantly lower than those in the preintervention group (35 in 27 patients versus [vs] 18 in eleven patients, P<0.001). However, there was no significant difference between length of ICU stay and mortality after pharmacist dosing adjustment, which was 8.93 days vs 7.68 days (P=0.26) and 30.10% vs 27.36% (P=0.39), respectively. Pharmacist dosing adjustment for patients receiving CRRT was well accepted by physicians, and was related with lower adverse drug event rates and ICU cost savings. These results may support the development of strategies to include a pharmacist in the multidisciplinary ICU team.

    Humoral-mediated as well as cell-mediated immunity is compromised in myeloma patients receiving treatment. Immunocompromised patients are at risk of developing herpes zoster. There is evidence from clinical trials that bortezomib therapy is associated with a significant risk of herpes zoster. It is the authors' clinical policy to administer long-term acyclovir prophylactically to all symptomatic myeloma patients. A retrospective review of the records of 125 myeloma patients who were treated with bortezomib and who also received routine acyclovir prophylaxis at the dose of 400 mg daily in >80% of patients was undertaken. Alternatives, used in <20% of patients, were 200 mg of acyclovir, 250/500 mg of valacyclovir, or 500 mg of famciclovir administered daily. This was accompanied by patient education regarding the importance of compliance with these prophylactic medications. The duration of bortezomib therapy was 1 to 164 weeks (median, 16 weeks). The total duration of exposure to bortezomib was 4150 weeks (80 patient-years). Except for the occasional missed dose, the self-reported compliance with antiviral prophylaxis was 100%. Not a single episode of herpes zoster was reported during this period. No adverse effects were noted that could be definitely attributed to acyclovir, valacyclovir, or famciclovir. Daily acyclovir (or a suitable alternative) appears to be effective at preventing herpes zoster virus in patients with myeloma who are receiving bortezomib, with or without corticosteroids.

    Radiation safety is an integral part of targeted radionuclide therapy. The aim of this work was to study the external dose rate and retained body activity as functions of time in differentiated thyroid carcinoma patients receiving 131I therapy. Seventy patients were stratified into two groups: the ablation group (A) and the follow-up group (FU). The patients' external dose rate was measured, and simultaneously, their retained body radiation activity was monitored at various time points. The equations of the external dose rate and the retained body activity, described as a function of hours post administration, were fitted. Additionally, the release time for patients was calculated. The reduction in activity in the group receiving a second or subsequent treatment was more rapid than the group receiving only the initial treatment. Most important, an expeditious method was established to indirectly evaluate the retained body activity of patients by measuring the external dose rate with a portable radiation survey meter. By this method, the calculated external dose rate limits are 19.2, 8.85, 5.08 and 2.32 μSv·h-1 at 1, 1.5, 2 and 3 m, respectively, according to a patient's released threshold level of retained body activity <400 MBq. This study is beneficial for radiation safety decision-making.

    Neuropathy is a common and potentially disabling complication of adjuvant taxane therapy. Recent studies have identified candidate single nucleotide polymorphisms associated with taxane-induced neuropathy. Therefore, we sought to determine whether neuropathy was associated with breast cancer recurrence in a clinical trial population who received adjuvant taxane therapy. Trial E1199 included 4,554 eligible women with operable breast cancer who received up to four cycles of doxorubicin and cyclophosphamide every 3 weeks followed by paclitaxel 175 mg/m(2) every 3 weeks for four cycles (P3), paclitaxel 80 mg/m(2) weekly for 12 cycles (P1), docetaxel 100 mg/m(2) every 3 weeks for four cycles (D3), or docetaxel 35 mg/m(2) weekly for 12 cycles (D1). A Cox proportional hazards model was used to determine the relationship between neuropathy and disease-free survival (DFS), overall survival (OS), and recurrence-free survival (RFS) by treating neuropathy status as a time dependent covariate and using a landmark analysis. Of 4,554 patients who received at least one taxane dose, grade 2 to 4 neuropathy developed in 18%, 22%, 15%, and 13% of patients in the P3, P1, D3, and D1 arms, respectively. In a model that included age, race, obesity, menopausal status, tumor size, nodal status, treatment arm, neuropathy, and hyperglycemia, no significant relationship was found between neuropathy and DFS, OS, or RFS. There was no association between taxane-induced neuropathy and outcome.

     Clinical guidelines for the use of opioids in chronic noncancer pain recommend assessing risk for aberrant drug-related behaviors prior to initiating opioid therapy. Despite recent dramatic increases in prescription opioid misuse and abuse, use of screening tools by clinicians continues to be underutilized. This research evaluated natural language processing (NLP) together with other data extraction techniques for risk assessment of patients considered for opioid therapy as a means of predicting opioid abuse.  Using a retrospective cohort of 3,668 chronic noncancer pain patients with at least one opioid agreement between January 1, 2007, and December 31, 2012, we examined the availability of electronic health record structured and unstructured data to populate the Opioid Risk Tool (ORT) and other selected outcomes. Clinician-documented opioid agreement violations in the clinical notes were determined using NLP techniques followed by manual review of the notes.  Confirmed through manual review, the NLP algorithm had 96.1% sensitivity, 92.8% specificity, and 92.6% positive predictive value in identifying opioid agreement violation. At the time of most recent opioid agreement, automated ORT identified 42.8% of patients as at low risk, 28.2% as at moderate risk, and 29.0% as at high risk for opioid abuse. During a year following the agreement, 22.5% of patients had opioid agreement violations. Patients classified as high risk were three times more likely to violate opioid agreements compared with those with low/moderate risk. CONCLUSION : Our findings suggest that NLP techniques have potential utility to support clinicians in screening chronic noncancer pain patients considered for long-term opioid therapy. © 2016 American Academy of Pain Medicine.

    Statins and angiotensin-converting enzyme (ACE) inhibitors have beneficial impact on the serum cholesterol and blood pressure. It is supposed that statins and ACE inhibitors may modify the antioxidative status of erythrocytes. The study objective was to compare the effects of two treatments, lisinopril alone vs lisinopril plus simvastatin, on erythrocyte antioxidant enzyme activities. The study involved 32 patients with arterial hypertension, the initial serum total cholesterol, LDL-cholesterol and triglycerides within the normal range. Patients of two groups, each of 16 subjects, were treated with lisinopril (10 mg/day) or with lisinopril (10 mg/day) plus simvastatin (20 mg/day). Before and after 3 and 6 months of follow-up therapy, activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx), glutathione reductase (GLR) in purified erythrocytes were determined. In all patients, significantly higher catalase activity (by 79.3-106.5%, p < 0.0001) and significantly lower GPx activity (by 20.7-30.6%, p < 0.001) were observed after therapy as compared to the baselines. Just the same results were obtained in both groups (lisinopril and lisinopril + simvastatin), after both periods (3 and 6 month) of treatments. SOD activity was increased only in the lisinopril group and only after 6 months (p = 0.0345). No changes of GLR reductase activity were seen under all conditions indicated. Thus, the lisinopril monotherapy and combined lisinopril plus simvastatin therapy exhibit specific, pronounced and equipotent effects on antioxidant enzymes in human erythrocytes. Administration of lisinopril or lisinopril plus simvastatin may protect erythrocytes and other tissues from oxidative damage.

    We present a case of severe lactic acidosis due to exacerbation of asthma in presence of normal tissue perfusion and oxygenation in a 35-year-old woman with poorly controlled asthma. After admission, she was treated continuously with inhalation of salbutamol (a beta-agonist) resulting in lactic acidosis, which was misinterpreted as treatment failure. The lactic acidosis reversed on discontinuation of the inhalation therapy. Although lactic acidosis is a rare complication to inhalation of beta-agonists, it is important for the clinicians to recognize this.

    Fibrinolytic proteases have potential applications in cardiovascular disease therapy. A novel fibrinolytic protease, AfeE, with strong thrombolytic activity was purified from Streptomyces sp. CC5. AfeE displayed maximum activity at 40°C in the pH range of 7.0-12.0. It was strongly inhibited by serine protease inhibitor phenylmethanesulfonylfluoride, soybean trypsin inhibitor, tosyl-l-lysine chloromethyl ketone and tosyl-l-phenylalanine chloromethyl ketone. The activity of the enzyme was partially inhibited by Cu(2+), Co(2+) and Zn(2+). AfeE exhibited higher substrate specificity for fibrin than fibrinogen, which has rarely been reported in fibrinolytic enzymes. AfeE also showed high thrombolytic activity in a carrageenan-induced mouse tail thrombosis model. AfeE prolonged prothrombin time, activated partial thromboplastin time, and thrombin time in rat blood. A bleeding time assay revealed that AfeE did not prolong bleeding time in mice at a dose of 1mg/kg. No acute cytotoxicity was observed for AfeE at 320μg/well in human umbilical vein endothelial cells. The afeE gene was cloned from the genome of Streptomyces sp. CC5. Full-length AFE-CC5E contained 434 amino acids and was processed into a mature form consisting 284 amino acids by posttranslational modification, as revealed by high-resolution mass spectrometry analysis. These results indicate that AfeE is a prospective candidate for antithrombotic drug development.

    Rates of treatment dropout in outpatient Dialectical Behavior Therapy (DBT) in the community can be as high as 24 % to 58 %, making dropout a great concern. The primary purpose of this article was to examine predictors of dropout from DBT in a community mental health setting. Participants were 56 consumers with borderline personality disorder (BPD) who were psychiatrically disabled participating in a larger feasibility trial of Dialectical Behavior Therapy- Accepting the Challenges of Exiting the System. The following variables were examined to see whether they predicted dropout in DBT: age, education level, baseline level of distress, baseline level of non-acceptance of emotional responses, and skills module in which a consumer started DBT skills group. These variables were chosen based on known predictors of dropout in consumers with BPD and in DBT, as well as an interest in what naturally occurring variables might impact dropout. The dropout rate in this sample was 51.8 %. Results of the logistic regression show that younger age, higher levels of baseline distress, and a higher level of baseline non-acceptance of emotional responses were significantly associated with dropout. The DBT skills module in which an individual started group did not predict dropout. The implications of these findings are that knowledge of consumer age and pretreatment levels of distress and non-acceptance of emotional responses can impact providers' choice of commitment and treatment strategies to reduce dropout. Future research should examine these strategies, as well as the impact of predictor variables on outcome and reasons for dropout.

    Poor nutritional status is associated with immunologic impairment and adverse health outcomes among adults infected with human immunodeficiency virus (HIV). We investigated body mass index (BMI), middle upper arm circumference (MUAC), and hemoglobin (Hgb) concentrations at initiation of antiretroviral therapy (ART) in 18,271 HIV-infected Tanzanian adults and their changes in the first 3 months of ART, in relation to the subsequent risk of death. Lower BMI, MUAC, and Hgb concentrations at ART initiation were strongly associated with a higher risk of death within 3 months. Among patients who survived >3 months after ART initiation, those with a decrease in weight, MUAC, or Hgb concentrations by 3 months had a higher risk of death during the first year. After 1 year, only a decrease in MUAC by 3 months after ART initiation was associated with a higher risk of death. Weight loss was associated with a higher risk of death across all levels of baseline BMI, with the highest risk observed among patients with BMI <17 kg/m(2) (relative risk, 7.9; 95% confidence interval, 4.4-14.4). Poor nutritional status at ART initiation and decreased nutritional status in the first 3 months of ART were strong independent predictors of mortality. The role of nutritional interventions as adjunct therapies to ART merits further investigation.

    Pancreatic ductal adenocarcinoma (PDA) is comprised of a prominent desmoplastic stromal compartment and only 10-40% of the tumour consists of PDA cells. However, how stromal components should be assessed and how the characteristics of the stromal compartment determine clinical outcomes in PDA patients remain unknown. A cohort of 66 consecutive patients who underwent pancreaticoduodenectomy and were primarily followed at Johns Hopkins Hospital between 1998 and 2004, and treated with adjuvant therapy, were included in a retrospective analysis. Resected PDA blocks with good tissue preservation were available for all patients. A new, computer-aided, quantitative method was developed to assess the density and activity of stroma in PDAs and the associations of these characteristics with clinical outcomes. High stromal density in resected PDA was found to be significantly associated with longer disease-free [adjusted hazard ratio (aHR) 0.39; P = 0.001] and overall (aHR 0.44; P = 0.004) survival after adjusting for the use of pancreatic cancer vaccine therapy, as well as gender and resection margin positivity. Stromal activity, representing activated pancreatic stellate cells in PDAs, was not significantly associated with the prognosis of resected PDAs. These results illustrate the complexity of the role of stroma in PDAs. Further exploration of the prognostic ability of the characteristics of stroma is warranted. © 2014 International Hepato-Pancreato-Biliary Association.

  6. Oral Anticoagulant Therapy in Patients Receiving Haemodialysis: Is It Time to Abandon It?

    2013-01-01

    Oral anticoagulant (OAC) therapy in haemodialysis patients causes a great deal of controversy. This is because a number of pro- and anticoagulant factors play an important role in end-stage renal failure due to the nature of the disease itself. In these conditions, the pharmacokinetic and pharmacodynamic properties of the OACs used change as well. In the case of the treatment of venous thromboembolism, the only remaining option is OAC treatment according to regimens used for the general population. Prevention of HD vascular access thrombosis with the use of OACs is not very effective and can be dangerous. However, OAC treatment in patients with atrial fibrillation in dialysis population may be associated with an increase in the incidence of stroke and mortality. Doubts should be dispelled by prospective, randomised studies; at the moment, there is no justification for routine use of OACs in the above-mentioned indications. In selected cases of OAC therapy in this group of patients, it is absolutely necessary to control and monitor the applied treatment thoroughly. Indications for the use of OACs in patients with end-stage renal disease, including haemodialysis patients, should be currently limited. PMID:24379737

    Purpose: We wanted to confirm the benefit of mometasone furoate (MF) in preventing acute radiation reactions, as shown in a previous study (Boström et al, Radiother Oncol 2001;59:257-265). Methods and Materials: The study was a double-blind comparison of MF with D (Diprobase), administered daily from the start of radiation therapy for 5 weeks in patients receiving breast radiation therapy, 40 Gy in 2.67-Gy fractions daily over 3 weeks. The primary endpoint was mean modified Radiation Therapy Oncology Group (RTOG) score. Results: Mean RTOG scores were significantly less for MF than for D (P=.046). Maximum RTOG and mean erythema scores were significantly less for MF than for D (P=.018 and P=.012, respectively). The Dermatology Life Quality Index (DLQI) score was significantly less for MF than for D at weeks 4 and 5 when corrected for Hospital Anxiety and Depression (HAD) questionnaire scores. Conclusions: MF cream significantly reduces radiation dermatitis when applied to the breast during and after radiation therapy. For the first time, we have shown a significantly beneficial effect on quality of life using a validated instrument (DLQI), for a topical steroid cream. We believe that application of this cream should be the standard of care where radiation dermatitis is expected.

    Doripenem dosing regimens for patients receiving continuous venovenous hemofiltration (CVVH) and continuous venovenous hemodiafiltration (CVVHDF) were devised based on an established efficacy criterion (free plasma doripenem concentrations above the minimum inhibitory concentration [fT > MIC] of 1 mg/L for ≥35% of the dosing interval) while maintaining exposure below that with the highest studied dose of 1000 mg infused over 1 hour every 8 hours in healthy subjects. Simulations were utilized to assure ≥90% probability of achieving the efficacy criterion with the recommended doripenem regimens. Inflated intersubject variability of 40% (coefficient of variation) was used for pharmacokinetic parameters (representative of clinical variation) and nonrenal clearance was doubled to account for potential changes with acute renal insufficiency. Results indicate that a reduction in doripenem dose will be needed for critically ill patients receiving CVVH or CVVHDF. This work was conducted to fulfill a health authority request and resulted in the addition of dosing recommendations to the Doribax Summary of Product Characteristics. PMID:22888451

    Implantable cardioverter-defibrillators (ICDs) have become the mainstay of preventive measures for sudden cardiac death (SCD). However, there are limited data on rates of appropriate life-saving ICD shock therapies in contemporary real-life settings. The purpose of the study was to evaluate the rate of appropriate life-saving ICD shock therapies in a contemporary registry. The Israeli ICD Registry includes all implants and other ICD operative procedures nationwide. The present study comprises 2349 consecutive cases who were enrolled in the Registry and prospectively followed up for information regarding survival, hospitalizations, and ICD therapies since 2010. Kaplan-Meier survival analysis showed that the rate of appropriate ICD shock therapy at 30-month follow-up was 2.6% among patients who received an ICD for primary prevention compared with 7.4% among those who received a device for secondary prevention (log-rank P < .001). Rates of appropriate ICD shocks among primary prevention patients were 1.1% at 1-year of follow-up and 2.6% at 30 months, whereas the corresponding rates in the secondary prevention group were 3.8% at 1 year and 7.4% at 30 months (log-rank P < .001). A total of 253 patients (4.8%) died during follow-up, 65% of noncardiac causes. Rates of life-saving appropriate ICD shock therapies among patients implanted with a defibrillator for the primary prevention of SCD in a contemporary real-world setting are lower than reported previously. These findings suggest a need for improved risk stratification and patient selection in this population. Copyright © 2015 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.

    There are increasing researches about non-communicable disease such as elevated blood pressure among people living with HIV before and after initiation of highly active antiretroviral therapy (HAART). This cross-sectional study was designed to determine the prevalence of hypertension and associated risk factors among 340 HIV-infected patients on antiretroviral therapy at a Malaysian public hospital providing HIV-related treatment. Data on socioeconomic background, anthropometry, medical history and dietary intake of the patients were collected. Hypertension is defined as blood pressure ≥130/85 (mm Hg). Prevalence of hypertension was 45.60% (n=155) of which 86.5% of the hypertensive group were male (n=134). The results showed that increase in age (OR 1.051, 95% confidence interval (CI) 1.024-1.078), higher body mass index (OR 1.18, 95% CI 1.106-2.71), bigger waist circumference (OR 1.18, 95%CI 1.106-2.71), higher waist-hip ratio (OR 1.070, 95%CI 1.034-1.106), higher fasting plasma glucose (OR 1.332, 95% CI 0.845-2.100) and percentage energy intake from protein >15 (OR 2.519, 95%CI 1.391-4.561) were significant risk factors for hypertension (p<0.001). After adjusting for other variables, increasing age (adjusted odds ratio (aOR) 1.069 95%CI 1.016-1.124, p=0.010), being male (aOR 3.026, 95%CI 1.175-7.794, p=0.022) and higher body mass index (aOR 1.26, 95%CI 1.032-1.551, p=0.024) were independently associated with hypertension. None of the antiretroviral therapy and immunologic factors was linked to hypertension. In conclusion hypertension among PLHIV was linked to the well-known risk factors such as age, gender and body mass index. With HAART, people can live longer by making monitoring and control of some reversible factors, especially excessive weight gain for maintaining quality of life. PMID:24576366

    Unintentional overdose involving opioid analgesics is a leading cause of injury-related death in the United States. To evaluate the feasibility and effect of implementing naloxone prescription to patients prescribed opioids for chronic pain. 2-year nonrandomized intervention study. 6 safety-net primary care clinics in San Francisco, California. 1985 adults receiving long-term opioid therapy for pain. Providers and clinic staff were trained and supported in naloxone prescribing. Outcomes were proportion of patients prescribed naloxone, opioid-related emergency department (ED) visits, and prescribed opioid dose based on chart review. 38.2% of 1985 patients receiving long-term opioids were prescribed naloxone. Patients prescribed higher doses of opioids and with an opioid-related ED visit in the past 12 months were independently more likely to be prescribed naloxone. Patients who received a naloxone prescription had 47% fewer opioid-related ED visits per month in the 6 months after receipt of the prescription (incidence rate ratio [IRR], 0.53 [95% CI, 0.34 to 0.83]; P = 0.005) and 63% fewer visits after 1 year (IRR, 0.37 [CI, 0.22 to 0.64]; P < 0.001) compared with patients who did not receive naloxone. There was no net change over time in opioid dose among those who received naloxone and those who did not (IRR, 1.03 [CI, 0.91 to 1.27]; P = 0.61). Results are observational and may not be generalizable beyond safety-net settings. Naloxone can be coprescribed to primary care patients prescribed opioids for pain. When advised to offer naloxone to all patients receiving opioids, providers may prioritize those with established risk factors. Providing naloxone in primary care settings may have ancillary benefits, such as reducing opioid-related adverse events. National Institutes of Health.

    The current study extends the findings of Scogin et al. (2007) by exploring the role of social support in changes in quality of life resulting from home-delivered cognitive behavioral therapy (CBT). One hundred thirty-seven participants, characterized primarily as rural, low resource, and frail, were randomly assigned to either CBT or a minimal support control condition. Hierarchical regression revealed that positive change in satisfaction with social support was associated with improvement in quality of life beyond the effects of the CBT treatment. In addition, pretreatment satisfaction with social support, and change in satisfaction with social support moderated the effect of CBT on quality of life. These results suggest that bolstering social support concomitant to CBT may increase quality of life. PMID:27011418

    Today, we frequently find patients taking oral anticoagulant therapy (OAT), a prophylaxis against the occurrence of thromboembolic events. An oral surgeon needs to know how to better manage such patients, in order to avoid hemorrhagic and thromboembolic complications. A group of 193 patients (119 men aged between 46 and 82 and 74 women aged between 54 and 76) undergoing OAT for more than 5 years were managed with a standardized management protocol and a 2-months follow-up. The aim of the present study was to apply a protocol, which could provide a safe intra- and postoperative management of patients on OAT. Among the 193 patients, only 2 had postoperative complications. We think that the protocol used in the present study can be used for complete safety in the treatment of this type of patients.

    Purpose: To evaluate the association between the interval from breast-conserving surgery (BCS) to radiotherapy (RT) and the clinical outcome among patients treated with adjuvant endocrine therapy. Patients and Methods: Patient information was obtained from three International Breast Cancer Study Group trials. The analysis was restricted to 964 patients treated with BCS and adjuvant endocrine therapy. The patients were divided into two groups according to the median number of days between BCS and RT and into four groups according to the quartile of time between BCS and RT. The endpoints were the interval to local recurrence, disease-free survival, and overall survival. Proportional hazards regression analysis was used to perform comparisons after adjustment for baseline factors. Results: The median interval between BCS and RT was 77 days. RT timing was significantly associated with age, menopausal status, and estrogen receptor status. After adjustment for these factors, no significant effect of a RT delay {<=}20 weeks was found. The adjusted hazard ratio for RT within 77 days vs. after 77 days was 0.94 (95% confidence interval [CI], 0.47-1.87) for the interval to local recurrence, 1.05 (95% CI, 0.82-1.34) for disease-free survival, and 1.07 (95% CI, 0.77-1.49) for overall survival. For the interval to local recurrence the adjusted hazard ratio for {<=}48, 49-77, and 78-112 days was 0.90 (95% CI, 0.34-2.37), 0.86 (95% CI, 0.33-2.25), and 0.89 (95% CI, 0.33-2.41), respectively, relative to {>=}113 days. Conclusion: A RT delay of {<=}20 weeks was significantly associated with baseline factors such as age, menopausal status, and estrogen-receptor status. After adjustment for these factors, the timing of RT was not significantly associated with the interval to local recurrence, disease-free survival, or overall survival.

    Aim There is limited information on the nutrition impact of antitumor necrosis factor-α treatment in adult Crohn's disease (CD). This study was performed to examine the effect of a 6-month course of infliximab on enterocyte function, nutrient status, metabolism, and body composition in these patients. Methods Seven CD patients were assessed for disease activity, enterocyte function, and body composition prior to, after 6 weeks, and after 6 months of infliximab treatment. Measurements included (1) disease activity: Inflammatory Bowel Disease Questionnaire, Harvey Bradshaw Index, and C-reactive protein; (2) enterocyte function: folate, homocysteine, vitamin B12, citrulline, vitamin D, β-carotene, d-xylose absorption; (3) Prognostic Inflammatory and Nutritional Index (PINI); and (4) body composition and metabolism: body mass index (BMI), fat and lean body mass, resting energy expenditure (RRE), and respiratory quotient. Results Most patients had improvement in disease activity with infliximab. PINI decreased in all patients (–3.35, P = .04). Plasma folate concentration significantly increased. There was an increase in BMI, fat mass, and lean body mass. The respiratory quotient increased in most patients. Changes in citrulline level and REE were inconsistent. Conclusions Crohn's disease patients have improvements in an index that measures both inflammation and nutrition (PINI) with infliximab therapy. Increases in plasma folate suggest improvement in enterocyte function and/or increased oral intake. The increase in respiratory quotient suggests decreased lipolysis and the lack of a starvation state. It was unclear whether weight gain was predominantly fat or lean muscle mass. These finding also support the use of PINI in Crohn's patients as an overall marker of inflammation and nutrition, and as a measure of response to infliximab therapy. PMID:18849561

    The impact of antiretroviral (ARV) therapy on immunological and growth parameters in HIV-positive children in Pakistan has not been reported to date. A retrospective chart review of children diagnosed with HIV at the Sindh AIDS Control Proigramme (SACP) and registered at the Aga Khan University, Karachi, between January 2005 and 2013 was conducted, evaluating clinical and laboratory profiles of HIV+ ARV+ children for ARV impact (serial height and weight CD4 and viral counts). Twenty-four children were diagnosed and registered as HIV positive over five years, and 20 were started on ARV. Six were excluded from analysis (ARV duration < 6 months). Nine (64.3%) of 14 fulfilled WHO criteria for treatment failure at a median duration of 25 weeks (IQR 18-32) on ARV and underwent resistance genotyping. All nine had NNRTI resistance, two had high-grade NRTI resistance (≥ 4 thymidine analog mutations). Median age at start of ARV was 71.5 weeks (IQR 37.5-119). Median baseline weight for age (WAZ) and height for age (HAZ) z-scores changed from -1.94 to 1.69 and -1.99 to -1.59, respectively, after six months of therapy. Median CD4 percentage and viral load at baseline changed from 13.8 to 17.8, while viral load changed from 285 × 104 copies to zero at six months. ARV improved absolute CD4 and viral counts. Weight and height did not  improve significantly, highlighting the need for aggressive nutritional rehabilitation. Early development of ARV resistance in these children requires formal assessment.

    Purpose To evaluate the association between time from breast-conserving surgery (BCS) to radiotherapy and clinical outcome among patients treated with adjuvant endocrine therapy. Methods Patient information was obtained from three International Breast Cancer Study Group trials. Analysis was restricted to 964 patients treated with BCS and adjuvant endocrine therapy. Patients were divided into two groups based on the median number of days between BCS and radiotherapy and into 4 groups based on the quartile of time between BCS and radiotherapy. Endpoints were time to local recurrence (TLR), disease-free survival (DFS) and overall survival (OS). Proportional hazards regression analysis was used to perform comparisons after adjustment for baseline factors. Results The median time between BCS and radiotherapy was 77 days. Radiotherapy timing was significantly associated with age, menopausal status, and estrogen receptor status. After adjustment for these factors no significant effect of radiotherapy delay of up to 20 weeks was found. Adjusted hazard ratios (HRs) (radiotherapy within 77 days vs. after 77 days) were 0.94 (95% CI 0.47–1.87) for TLR, 1.05 (95% CI 0.82–1.34) for DFS and 1.07 (95% CI 0.77–1.49) for OS. For TLR the adjusted HRs for ≤48 days, 49–77 days, and 78–112 days were 0.90 (CI 95% 0.34–2.37), 0.89 (95% CI, 0.33–2.25), and 0.89 (95% CI, 0.33–2.41), respectively relative to ≥ 113 days. Conclusions Radiotherapy delay of up to 20 weeks was significantly associated with baseline factors such as age, menopausal status, and estrogen-receptor status. After adjustment for these factors, timing of radiotherapy was not significantly associated with TLR, DFS, or OS. PMID:20729007

    Background The selection of the most appropriate treatment combinations requires the balancing of benefits and harms of these treatment options as well as the patients’ preferences for the resulting outcomes. Objective This research aimed at estimating and comparing the utility weights between elderly women with early stage hormone receptor positive (HR+) breast cancer receiving a combination of radiotherapy and hormonal therapy after breast conserving surgery (BCS) and those receiving a combination of BCS and hormonal therapy. Methods The Surveillance, Epidemiology, and End Results (SEER) linked with Medicare Health Outcomes Survey (MHOS) was used as the data source. Health utility weights were derived from the VR-12 health-related quality of life instrument using a mapping algorithm. Descriptive statistics of the sample were provided. Two sample t-tests were performed to determine potential differences in mean health utility weights between the two groups after propensity score matching. Results The average age at diagnosis was 72 vs. 76 years for the treated and the untreated groups, respectively. The results showed an inverse relationship between the receipt of radiotherapy and age. Patients who received radiotherapy had, on average, a higher health utility weight (0.70; SD = 0.123) compared with those who did not receive radiotherapy (0.676; SD = 0.130). Only treated patients who had more than two comorbid conditions had significantly higher health utility weights compared with patients who were not treated. Conclusions The mean health utility weights estimated for the radiotherapy and no radiotherapy groups can be used to inform a comparative cost-effectiveness analysis of the treatment options. However, the results of this study may not be generalizable to those who are outside a managed care plan because MHOS data is collected on managed care beneficiaries. PMID:27819160

    Prostate cancer is the most commonly diagnosed non-melanoma cancer among men. Androgen deprivation therapy (ADT) has been the core therapy for men with advanced prostate cancer. It is only in recent years that clinicians began to recognize the cognitive-psychosocial side effects from ADT, which significantly compromise the quality of life of prostate cancer survivors. The objectives of the study are to determine the efficacy of a simple and accessible home-based, walking exercise program in promoting cognitive and psychosocial functions of men with prostate cancer receiving ADT. A 6-month prospective, single-blinded, randomized controlled trial will be conducted to compare the Exercise Group with the Control Group. Twenty men with prostate cancer starting ADT will be recruited and randomly assigned to one of the two groups: the Exercise Group will receive instructions in setting up an individualized 6-month home-based, walking exercise program, while the Control Group will receive standard medical advice from the attending physician. The primary outcomes will be psychosocial and cognitive functions. Cognitive functions including memory, attention, working memory, and executive function will be assessed using a battery of neurocognitive tests at baseline and 6 months. Psychosocial functions including depression, anxiety and self-esteem will be assessed at baseline, 3 and 6 months using the Center for Epidemiological Studies Depression Scale, Spielberger State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale. The significance of the cognitive-psychosocial side effects of ADT in men with prostate cancer has only been recently recognized, and the management remains unclear. This study addresses this issue by designing a simple and accessible home-based, exercise program that may potentially have significant impact on reducing the cognitive and psychosocial side effects of ADT, and ultimately improving the health-related quality of life in men with prostate

    Hepatitis B virus (HBV) is an important cause of comorbidity in human immunodeficiency virus (HIV)-infected individuals. The immunogenicity of HBV vaccination in children receiving highly active antiretroviral therapy (HAART) was investigated. HIV-infected children receiving HAART who had low to moderate HIV loads and who had previously received 3 doses of HBV vaccine were given an HBV vaccine booster. Concentrations of antibody to hepatitis B surface antigen (anti-HBs) were determined before vaccination and at weeks 8, 48, and 96. A subset of subjects was administered a subsequent dose, and anti-HBs was measured before and 1 and 4 weeks later. At entry, 24% of 204 subjects were seropositive. Vaccine response occurred in 46% on the basis of seropositivity 8 weeks after vaccination and in 37% on the basis of a 4-fold rise in antibody concentration. Of 69 subjects given another vaccination 4-5 years later, immunologic memory was exhibited by 45% on the basis of seropositivity 1 week after vaccination and by 29% on the basis of a 4-fold rise in antibody concentration at 1 week. Predictors of response and memory included higher nadir and current CD4 cell percentage, higher CD19 cell percentage, and undetectable HIV load. HIV-infected children frequently lack protective levels of anti-HBs after previous HBV vaccination, and a significant proportion of them do not respond to booster vaccination or demonstrate memory despite receiving HAART, leaving this population insufficiently protected from infection with HBV.

    2004 U.S. dollars using the consumer price index for medical care. T tests were used for descriptive cost comparisons. Generalized linear models (GLMs) were used to compare costs of adults receiving alternative therapies, adjusting for demographic characteristics, substance abuse, depression, and the Charlson Comorbidity Index. Of the 4,569 patients who received 1 of these 3 drug therapies for ADHD, 31.8% received OROS-MPH for a median duration of 99 days of therapy, 34.0% received MAS-XR for a median 128 days, and 34.2% received atomoxetine for a median 86 days. In the 6-month follow-up period, the mean (standard deviation) total medical and drug costs were $2,008 ($3,231) for OROS-MPH, $2,169 ($4,828) for MAS-XR, and $2,540 ($4,269) for atomoxetine-treated adults. The GLM for patient characteristics suggested that 6-month, risk-adjusted mean medical costs, excluding drug costs, for adults treated with OROS-MPH were $142 less (10.4%, $1,220 vs. $1,362) compared with MAS-XR (P =0.022) and $132 less (9.8%, $1,220 vs. $1,352) compared with atomoxetine (P =0.033); risk-adjusted mean medical costs were not significantly different between MAS-XR and atomoxetine. The GLM comparison of risk-adjusted total direct costs, including drug cost, was on average $156 less (8.0%, $1,782 vs. $1,938) for OROS-MPH compared with MAS-XR (P = 0.017) and $226 less (11.3%, $1,782 vs. $2,008) compared with atomoxetine (P <0.001); the risk-adjusted total direct costs were not significantly different between MAS-XR and atomoxetine. Two high-cost outliers (greater than 99.96th percentile, 1 each for OROS-MPH and atomoxetine) accounted for $47 (30%) of the $156 cost difference between OROS-MPH and MAS-XR and $11 (5%) of the $226 cost difference between OROS-MPH and atomoxetine, and the medical diagnoses for the highest-cost claims for these 2 outlier patients were unrelated to ADHD.

    Study Design Secondary analysis of a randomized trial. Background A clinical prediction rule to identify patients with carpal tunnel syndrome (CTS) most likely to respond to manual physical therapy has been published but requires further testing to determine its validity. Objective To assess the validity of a clinical prediction rule proposed for the management of patients with CTS in a different group of patients with a variety of treating clinicians. Methods A preplanned secondary analysis of a randomized controlled trial investigating the efficacy of manual physical therapies, including desensitization maneuvers of the central nervous system, in 120 women suffering from CTS was performed. Patients were randomized to receive 3 sessions of manual physical therapy (n = 60) or surgical release/decompression of the carpal tunnel (n = 60). Self-perceived improvement with a global rating of change was recorded at 6- and 12-month follow-ups. Pain intensity (mean pain and worst pain on a 0-to-10 numeric pain-rating scale) and scores on the Boston Carpal Tunnel Questionnaire (functional status and symptom severity subscales) were assessed at baseline and at 1, 3, 6, and 12 months. A baseline assessment of status on the clinical prediction rule was performed (positive status on the clinical prediction rule was defined as meeting at least 2 of the following criteria: pressure pain threshold of less than 137 kPa over the affected C5-6 joint; heat pain threshold of less than 39.6°C over the affected carpal tunnel; and general health score [Medical Outcomes Study 36-Item Short-Form Health Survey] of greater than 66 points). Linear mixed models with repeated measures were used to examine the validity of the rule. Results Participants with a positive status on the rule who received manual physical therapy did not experience greater improvements compared to those with a negative status on the rule for mean pain (P = .65), worst pain (P = .86), function (P = .99), or symptom

    Music therapy is a common discretionary service offered within hospice; however, there are critical gaps in understanding the effects of music therapy on hospice quality indicators, such as family satisfaction with care. The purpose of this study was to examine whether music therapy affected family perception of patients' symptoms and family satisfaction with hospice care. This was a retrospective, cross-sectional analysis of electronic medical records from 10,534 cancer patients cared for between 2006 and 2010 by a large national hospice. Logistic regression was used to estimate the effect of music therapy using propensity scores to adjust for non-random assignment. Overall, those receiving music therapy had higher odds of being female, having longer lengths of stay, and receiving more services other than music therapy, and lower odds of being married/partnered or receiving home care. Family satisfaction data were available for 1495 (14%) and were more likely available if the patient received music therapy (16% vs. 12%, P < 0.01). There were no differences in patient pain, anxiety, or overall satisfaction with care between those receiving music therapy vs. those not. Patients who received music therapy were more likely to report discussions about spirituality (odds ratio [OR] = 1.59, P = 0.01), had marginally less trouble breathing (OR = 0.77, P = 0.06), and were marginally more likely to receive the right amount of spiritual support (OR = 1.59, P = 0.06). Music therapy was associated with perceptions of meaningful spiritual support and less trouble breathing. The results provide preliminary data for a prospective trial to optimize music therapy interventions for integration into clinical practice.

    Purpose: Patients with bone metastases have a widely varying survival. A reliable estimation of survival is needed for appropriate treatment strategies. Our goal was to assess the value of simple prognostic factors, namely, patient and tumor characteristics, Karnofsky performance status (KPS), and patient-reported scores of pain and quality of life, to predict survival in patients with painful bone metastases. Methods and Materials: In the Dutch Bone Metastasis Study, 1157 patients were treated with radiation therapy for painful bone metastases. At randomization, physicians determined the KPS; patients rated general health on a visual analogue scale (VAS-gh), valuation of life on a verbal rating scale (VRS-vl) and pain intensity. To assess the predictive value of the variables, we used multivariate Cox proportional hazard analyses and C-statistics for discriminative value. Of the final model, calibration was assessed. External validation was performed on a dataset of 934 patients who were treated with radiation therapy for vertebral metastases. Results: Patients had mainly breast (39%), prostate (23%), or lung cancer (25%). After a maximum of 142 weeks' follow-up, 74% of patients had died. The best predictive model included sex, primary tumor, visceral metastases, KPS, VAS-gh, and VRS-vl (C-statistic = 0.72, 95% CI = 0.70-0.74). A reduced model, with only KPS and primary tumor, showed comparable discriminative capacity (C-statistic = 0.71, 95% CI = 0.69-0.72). External validation showed a C-statistic of 0.72 (95% CI = 0.70-0.73). Calibration of the derivation and the validation dataset showed underestimation of survival. Conclusion: In predicting survival in patients with painful bone metastases, KPS combined with primary tumor was comparable to a more complex model. Considering the amount of variables in complex models and the additional burden on patients, the simple model is preferred for daily use. In addition, a risk table for survival is provided.

    Polycythemia vera (PV) is characterized by erythropoiesis and JAK2-activating mutations, with increased risks of morbidity and mortality. Most patients with PV are iron deficient, and treatment often includes hematocrit control with phlebotomy, which may exacerbate iron deficiency-associated complications. The phase 3 RESPONSE trial evaluated the JAK1/JAK2 inhibitor ruxolitinib (n=110) versus best available therapy (BAT; n=112) in patients with PV who were hydroxyurea-resistant/intolerant. Ruxolitinib was superior to BAT for hematocrit control, reduction in splenomegaly, and blood count normalization. This exploratory analysis, the first to evaluate iron status in a prospective study of patients with PV, investigated ruxolitinib effects on 7 serum iron markers and iron deficiency-related patient-reported outcomes (PRO). Among patients with evidence of baseline iron deficiency, ruxolitinib was associated with normalization of iron marker levels, compared with lesser improvement with BAT. Iron levels remained stable in ruxolitinib patients with normal iron levels at baseline. Regardless of baseline iron status, treatment with ruxolitinib was associated with improvements in concentration problems, cognitive function, dizziness, fatigue, headaches, and inactivity, although improvements were generally greater among patients with baseline iron deficiency. The improvements in iron deficiency markers and PROs observed with ruxolitinib are suggestive of clinical benefits that warrant further exploration. Copyright © 2017 The Authors.

    A 69-year-old woman was diagnosed with alveolar rhabdomyosarcoma (ARMS) of the nasopharynx. She has a history of catastrophic thromboembolic event in the abdomen that caused short-gut syndrome and dependence on total parenteral nutrition (TPN) twelve hours per day. She was treated for short-gut syndrome with teduglutide, a glucagon-like peptide-2 (GLP-2) analog, which led to reduction of TPN requirements. However, a few months later, she developed metastatic alveolar rhabdomyosarcoma. Though a causative relationship is unlikely between the peptide and ARMS due to the brief time course between teduglutide therapy and sarcoma diagnosis, neoplastic growth may have been accelerated by the GLP-2 analog, causing release of IGF-1. The transmembrane receptor for IGF-1 is frequently overexpressed in ARMS and is implicated in cell proliferation and metastatic behavior. This case describes a rare incidence of metastatic alveolar rhabdomyosarcoma in a sexagenarian and possibly the first case reported associated with the use of teduglutide. Teduglutide was discontinued due to a potential theoretical risk of acceleration of sarcoma growth, and the patient's rhabdomyosarcoma is in remission following sarcoma chemotherapy. PMID:26266067

    Insulin resistance (IR) is a putative risk factor for cognitive decline and dementia, and has been shown to impede neuronal glucose metabolism in animal models. This post hoc study focused on metabolic changes in the medial prefrontal region, a brain region exhibiting decline years before documented cognitive changes, relative to high or low IR status in a cohort of postmenopausal women at risk for dementia who were randomized to continue or discontinue existing stable hormone therapy (HT) for 2 years. Subjects were dichotomized into high and low IR groups based on the homeostatic model assessment of insulin resistance, which was within clinically normal limits for the group as a whole at both baseline and 2-year follow-up. Results showed that high and low IR groups showed significant differences in metabolic decline of the medial prefrontal gyrus, regardless of HT randomization group. However, HT randomization was predictive of metabolic decline only in women with low HOMA (homeostatic assessment of insulin resistance). Performance in working memory was consistent with observed metabolic changes. These results suggest IR may be an independent moderator of regional metabolic changes, while protective metabolic effects of HT are most apparent in those at low-end range of IR. If replicated in future studies, these findings will help to better understand the interaction between putative risk and protective factors, and further delineate cohort postmenopausal women who may benefit from HT.

    Complications of respiratory system in patients suffering from chronic renal failure who are treated with regular haemodialysis are well known. However, the influence of the duration of haemodialysis on pulmonary function is less understood. The aim of this study was to determine spirometry changes in patients on chronic haemodialysis over a five-year period. We tested 21 patients, out of which 11 female and 10 male, mean age of 50 (+/- 11) years. The mean duration of haemodialysis was 52.2 (+/- 44.7) months at the time of the inclusion. We performed spirometry testings in all patients, one hour before start and one hour after completion of haemodialysis. All parameters of spirometry recorded one hour after completion of haemodialysis (FVC, FEV1, FEF75, 50, 25, % of predicted), improved significantly (p < 0.01). After five years, only FVC demonstrated significant decline and none of the recorded spirometry parameters improved significantly one hour post haemodialysis compared to pre-haemodialysis period. Analysis of post-dialysis parameters of spirometry at the study onset and following five years of haemodialysis showed that all parameters, except FEF50 (p > 0.05), significantly deteriorated (p < 0.01). Patients who are on long-term haemodialysis show a significant decline in FVC following five years of treatment. Although the spirometry changes in observed population treated with chronic haemodialysis have reversible character during the first years of renal replacement therapy, five years after these changes become irreversible.

    It could be postulated that due to lifestyle factors, patients with poor antiretroviral therapy (ART) adherence may also have risky sexual behaviour potentially leading to HIV transmission. There are limited data regarding unprotected sex risk and ART adherence in resource limited settings and our study set out to investigate these in an HIV clinic in Bangkok. Patients completed an anonymous questionnaire regarding their relationship details, ART adherence, sexual behaviour, alcohol and drug use and HIV transmission beliefs. Laboratory findings and medical history were also collected. Unprotected sex risk (USR) was defined as inconsistent condom use with a partner of negative or unknown HIV status. Five hundred and twelve patients completed the questionnaire. Fifty seven per cent of patients reported having taken ARV >95% of the time in the last month and 58% had been sexually active in the previous 30 days. Only 27 patients (5%) were classified as having USR in our cohort. Multivariate analysis showed USR was associated with female gender (OR 2.9, 95% CI 1.2-7.0, p0.02) but not with adherence, age, type or number of partners, recreational drug or alcohol use nor beliefs about HIV transmission whilst taking ART. Levels of USR in this resource limited setting were reassuringly low and not associated with poor ART adherence; as all USR patients had undetectable viral loads onward HIV transmission risk is likely to be low but not negligible. Nonetheless condom negotiation techniques, particularly in women, may be useful in this group.

    Using multidimensional scaling (MDS) analysis, this study examined how patient conceptualisations of treatment motivation compare with theoretically based assumptions used in current assessment approaches. Patients undergoing antiretroviral therapy for HIV/AIDS (n=39) rated for similarity between all possible pairings of 23 treatment descriptions, including descriptors of intrinsic, extrinsic, approach and avoidance motivation. MDS analyses revealed that patient perceptions of intrinsic and extrinsic motivations often differ from those based on definitions derived from common interpretations of self-determination theory. Findings also showed that patients reported motivation for avoiding treatment when they associated their medication regimens with side effects and other negatively valenced outcomes. The study describes new applications of MDS in assessing how patients perceive the relationship between treatment behaviours and specific forms of motivation, such as intrinsic and extrinsic motivations. In addition, the study suggests how MDS may be used to develop behavioural strategies aimed at helping patients follow their regimens consistently by identifying treatment conceptualisations and contexts that facilitate or impede adherence.

    Human immunodeficiency virus (HIV)-induced peripheral neuropathy is the most common neurologic complication associated with HIV infection. In addition to virus-mediated injury of the peripheral nervous system (PNS), treatment of HIV infection with combination antiretroviral therapy (cART) may induce toxic neuropathy as a side effect. Antiretroviral toxic neuropathy is clinically indistinguishable from the sensory neuropathy induced by HIV; in some patients, these 2 processes are likely superimposed. To study these intercurrent PNS disease processes, we first established a simian immunodeficiency virus (SIV)/pigtailed macaque model in which more than 90% of animals developed PNS changes closely resembling those seen in HIV-infected individuals with distal sensory neuropathy. To determine whether cART alters the progression of SIV-induced PNS damage, dorsal root ganglia and epidermal nerve fibers were evaluated in SIV-infected macaques after long-term suppressive cART. Although cART effectively suppressed SIV replication and reduced macrophage activation in the dorsal root ganglia, PGP 9.5 immunostaining and measurements of epidermal nerve fibers in the plantar surface of the feet of treated SIV-infected macaques clearly showed that cART did not normalize epidermal nerve fiber density. These findings illustrate that significant PNS damage persists in SIV-infected macaques on suppressive cART.

    Cognition can be affected by electroconvulsive therapy (ECT). Good clinical practice includes neuropsychological assessment, although this is seldom a part of routine clinical practice. It looks like a substantial part of patients fail to complete cognitive assessments. This constitutes a problem in the generalizability of published clinical research on cognitive side effects. Most studies of ECT-related cognitive adverse effects do not discuss this important issue of so-called cognitive test nonparticipants. Recent findings suggest that cognitive test nonparticipants are more severely ill, and probably more vulnerable to cognitive side effects. To examine the feasibility of a neuropsychological test battery in daily clinical practice, in an adult population referred for ECT. We reviewed the clinical records of 84 patients referred for ECT. Demographic and clinical characteristics of those patients who were able to complete our routine cognitive testing at baseline are compared with those who could not complete the assessment. From 84 ECT patients, 60 (71%) completed a pre-ECT cognitive assessment, whereas 24 (29%) did not. Patients with a unipolar depression, with psychotic symptoms, who started their treatment with a bitemporal electrode placement were more likely to be test noncompleters than test completers. Patients with a unipolar depression, with psychotic features, who are treated with a bitemporal electrode placement, have a higher likelihood of not completing a pre-ECT cognitive assessment. These patients probably represent a subgroup more vulnerable to cognitive side effects.

    This study reports on the emergence of cfr-harbouring coagulase-negative staphylococci (CoNS) among patients who received linezolid therapy in two hospitals in Hangzhou, China. The mechanisms of resistance and transmission were analysed for these resistant isolates. Eight Staphylococcus capitis isolates, one Staphylococcus epidermidis isolate and one Staphylococcus hominis isolate, obtained from patients who had received linezolid therapy in two hospitals in Hangzhou, China, were confirmed as linezolid resistant, with MICs ranging from 8 to >256 mg l(-1). The linezolid usage data of the ten patients before isolation of the linezolid-resistant CoNS were collected. PFGE analysis showed that the eight S. capitis isolates from the two hospitals belonged to the same clone. Nine of the linezolid-resistant CoNS isolates carried the cfr gene, which was located on plasmids of a similar size. A 5.3 kb fragment containing the cfr gene, revealing 99 % identity to the sequence of the cfr-harbouring plasmid pSS-01 reported previously, was determined by PCR mapping for all cfr-positive isolates, and the cfr gene was flanked by two copies of IS256-like elements. Thus, these results document the emergence of linezolid-resistant CoNS isolates carrying the cfr gene in Hangzhou, China. Effective nosocomial infection control strategies and the judicious use of antibiotics will be required to prevent further spread of this resistance mechanism.

    In more than 20 years of medical practice, a surprising phenomenon has often occurred: some patients with acquired immunodeficiency syndrome (AIDS) decide not to go to the hospital and they do not let others know that they are suffering from the disease unless they believe that they are dieing. Zhang Shan (a pseudonym) is one such patient with human immunodeficiency virus (HIV)/AIDS who was reluctant to receive antiviral therapy as soon as possible, and this paper shares Zhang's story as he related it. Clearly, there are numerous views as to why patients in China behave as Zhang did. Presented here are several reasons, including society, history, morality and ideology, family, and education. Although all of these reasons do play a role, the patient's mindset and behavior is the most significant reason for a patient's reluctance to seek treatment or disclose his/her status. If the individual patient's mindset and behavior are not dealt with effectively, then HIV/AIDS can continue to spread and threaten additional lives and even the fabric of society. This paper analyzes the reasons why patients are hesitant to receive antiviral therapy, but this paper also suggests steps healthcare personnel can take to encourage patients to seek treatment. Such steps can save the lives of current patients with HIV/AIDS. In addition, sound public health measures and a rational approach to treatment are important to helping potential patients with HIV/AIDS.

    One of the adverse effects of the tumour necrosis factor alpha [[TNFα] monoclonal antibodies for the treatment of immune-mediated inflammatory diseases is a higher propensity for tuberculosis development. The aim of this study was to explore the utility and sensitivity of serial tuberculosis screening during anti-TNFα treatment. A cohort of 46 inflammatory bowel disease patients receiving infliximab was prospectively recruited and followed for 26 months. During this period of time, a tuberculosis skin test and two different interferon ϒ release assays [QFT-GIT and T-SPOT.TB] were applied at 4-6-month intervals. Overall, 16 patients were diagnosed with latent tuberculosis infection after having at least one test conversion: 12 patients had a positive tuberculosis skin test, seven patients had a positive T-SPOT.TB, and two patients had a positive QFT-GIT. Active tuberculosis was excluded in all; 15 were treated with isoniazid. A comparison between tests showed a moderate accuracy [72% to 85%] but low kappa values [0.063 to 0.377]. Concerning association with demographic and clinical characteristics, test conversion was more common among the male gender and those with a longer disease duration. Tuberculosis tests conversions were common in inflammatory bowel disease patients treated with infliximab alone or in association with immunomodulators. In these immunosuppressed individuals, the classical tuberculosis skin test seems to have a higher sensitivity than the modern tests based on the release of interferonϒ.

    Antifungal catheter lock therapy (AfLT) with liposomal amphotericin B has been used in the treatment of pediatric central line infections caused by Candida species; however, reports describing the use of liposomal amphotericin B lock therapy in the adult hemodialysis patient population are lacking. Management of central line-associated candidemia with systemic therapy alone is often challenging due to the propensity of Candida species to form biofilms on foreign bodies. We describe a 64-year-old woman who was receiving hemodialysis 3 times/week and was hospitalized with persistent fungemia. Despite receiving intravenous micafungin, she had multiple positive blood cultures for Candida albicans, which finally cleared after 7 days. Her double-lumen catheter was considered the most likely nidus of infection. Although catheter removal would have been preferred, this was not possible given her vasculopathy, history of multiple bloodstream infections, and lack of other available sites for vascular access. Catheter exchange was performed, and liposomal amphotericin B AfLT was administered in combination with intravenous micafungin for a total of 6 days. During this time, the patient experienced no discernible adverse effects secondary to AfLT. At discharge, AfLT was discontinued, and intravenous micafungin was changed to oral fluconazole. After 6 months of treatment, the patient remained culture negative and maintained her dialysis access. To our knowledge, this is the first case report of liposomal amphotericin B catheter lock therapy used to manage a persistent C. albicans bloodstream infection in an adult receiving hemodialysis. AfLT is a novel concept for treating catheter-associated fungal infections. Liposomal amphotericin B was chosen based on its favorable in vitro activity against Candida species biofilms in catheter lock environments. We identified several barriers to implementing AfLT, and these issues may prohibit the use of AfLT. This case report

    Purpose: To determine the impact of a pharmacist-driven medication therapy management (MTM) program for patients receiving oral chemotherapy agents. Methods: We assessed the impact of MTM consultations with a pharmacist for patients who were receiving a new prescription for an oral chemotherapy agent. Data were assessed for outcomes including (1) number of medication errors identified in electronic medical records (EMRs), (2) number of interventions performed by the pharmacist, (3) time spent on the MTM process, and (4) patient satisfaction. Data were compared between patients who received their oral chemotherapy agents from the onsite specialty pharmacy or from a mail-order pharmacy. The data were also examined for correlations, and logistic regression was utilized to determine the largest variant cofactor to create an equation for estimating the number of errors in a patient's EMR. Results: Fifteen patients received an MTM consultation, and the pharmacists identified an average of 6 medication EMR errors per patient. There was an average of 3 pharmacist-led interventions per patient. Multiple significant correlations were noted between the variables: (1) total number of prescriptions a patient was taking, (2) total number of medication errors identified, (3) time spent on the MTM process, and (4) total number of interventions performed by the pharmacist. Patient satisfaction was favorable for the program. Conclusion: The implementation of a pharmacist-driven MTM program for patients receiving a prescription for an oral chemotherapy agent had a significant impact on patient care by improving medication reconciliation, identifying drug-related problems, and strengthening pharmacist-patient interactions in the oncology clinic.

    Background Little is known about the impact of pregnancy on response to highly active antiretroviral therapy (HAART) in sub-Saharan Africa. We examined the effect of incident pregnancy after HAART initiation on clinical response to HAART. Methods We evaluated a prospective clinical cohort of adult women initiating HAART in Johannesburg, South Africa between 1 April 2004 and 31 March 2011, and followed up until an event, transfer, drop-out, or administrative end of follow-up on 30 September 2011. Women over age 45 and women who were pregnant at HAART initiation were excluded from the study. Main exposure was having experienced pregnancy after HAART initiation; main outcome was death and (separately) death or new AIDS event. We calculated adjusted hazard ratios (HRs) and 95% confidence limits (CL) using marginal structural Cox proportional hazards models. Results The study included 7,534 women, and 20,813 person-years of follow-up; 918 women had at least one recognized pregnancy during follow-up. For death alone, the weighted (adjusted) HR was 0.84 (95% CL 0.44, 1.60). Sensitivity analyses confirmed main results, and results were similar for analysis of death or new AIDS event. Incident pregnancy was associated with a substantially reduced hazard of drop-out (HR = 0.62, 95% CL 0.51, 0.75). Conclusions Recognized incident pregnancy after HAART initiation was not associated with increases in hazard of clinical events, but was associated with a decreased hazard of drop-out. High rates of pregnancy after initiation of HAART may point to a need to better integrate family planning services into clinical care for HIV-infected women. PMID:23520489

    The aim of this study was to describe the population pharmacokinetics of cefepime in septic shock patients requiring continuous renal replacement therapy and to determine whether current or alternative dosing regimens can achieve PK/PD targets. In this observational PK study, 62 samples from 13 patients were analysed using non-linear mixed-effects modelling. Different dosing regimens were evaluated using Monte Carlo simulations with ultrafiltration flow rates (UFRs) of 1000, 1500 and 2000 mL/h. The probability of target attainment was calculated against a conservative (60% T(>MIC)) and a higher PK/PD target (100% T(>MIC)) against an MIC of 8 mg/L, the clinical susceptibility breakpoint for Pseudomonas aeruginosa. A one-compartment model with between-subject variability (BSV) on clearance and volume of distribution (V(d)) described the data adequately. UFR was supported as a covariate on both parameters. Typical values for clearance and V(d) were 4.4L/h (BSV 37%) and 40.9L (BSV 20%), respectively. Dosing simulations showed failure to achieve both a conservative and a higher PK/PD target using a dose of 1g q12h for patients treated with a high UFR (≥1500 mL/h). The dose of 2g q8h or 1g q6h leads to optimal target attainment for high UFR. One gram q8h is optimal for low UFR (≤1000 mL/h). We found important variability in PK parameters. Dosing simulations show that a dose of 2g q8h or 1g q6h is needed to ensure rapid achievement of adequate levels if the UFR is ≥1500 mL/h and 1g q8h for low UFR (≤1000 mL/h).

    Opiate substitution therapy (OST) reduces the risk of death from directly drug-related causes in heroin users, allowing other chronic health problems to emerge. People who inject drugs (PWID) are exposed to hepatitis C virus (HCV), with an associated risk of chronic liver disease. We investigated HCV prevalence and liver-related morbidity in a cohort of OST recipients, and analyzed factors associated with significant hepatic fibrosis. All patients registered on 1 April 2008 in 4 clinics providing OST in the 3 largest cities in Sweden were eligible for inclusion. HCV viremic subjects were evaluated for fibrosis stage by liver biopsy, transient elastometry (TE), and/or a biochemical fibrosis index (Göteborg University Cirrhosis Index; GUCI). Factors associated with severity of fibrosis were determined by logistic regression analysis. Out of 524 eligible patients, 277 consented to enrolment. Two hundred and thirty-six subjects (88%) were anti-HCV-positive, and 162 of these were viremic (69%). Significant liver fibrosis (defined as Ishak stages F3-F6, TE value ≥ 8.85 kPa, or GUCI > 0.33) was found in 69 out of 103 (67%) tested viremic patients, and was associated with alcohol intake (p = 0.03), higher body mass index (BMI; p = 0.04), and the presence of anti-HBc antibodies (indicating exposure to hepatitis B virus (HBV); p = 0.02). Significant liver fibrosis was detected in two-thirds of HCV viremic OST recipients in this cohort, and was associated with alcohol use, high BMI, and exposure to HBV. These findings indicate that the management of HCV and associated risk factors should be emphasized in Swedish OST programs.

    Renal insufficiency is recognized as a predictor of mortality and poor outcome in heart failure patients. We sought to study the impact of baseline serum creatinine on subsequent outcome in cardiac resynchronization therapy (CRT) recipients. We retrospectively reviewed hospital records of all CRT recipients at Pittsburgh Veterans Affairs (VA) Healthcare System (2003-2005) and University of Pittsburgh Medical Center (2004). We recorded clinical characteristics at the time of implantation including demographics, New York Heart Association (NYHA) functional class, ejection fraction, QRS duration, cardiomyopathy etiology, medical history, medication use, and serum creatinine. Mortality alone and mortality combined with heart failure hospitalization were the study endpoints. Out of the 330 patients studied, a total of 66 (20.0%) patients died over a mean follow-up duration of 19.7 +/- 9.0 months (range 1-44). The cohort was studied by three creatinine tertiles (0.6-1.0, 1.1-1.3, 1.4-3.0 mg/dL). Both study endpoints were observed more frequently in patients in the highest creatinine tertile compared to others (28.7% vs 14.0%, P = 0.008 for death and 41.6% vs 21.5%, P = 0.001 for the combined endpoint). High creatinine remained an independent predictor of mortality (hazard ratio [HR] 1.89, 95% confidence interval [CI] 1.06-3.39, P = 0.032) and the combined endpoint (HR 1.94, 95% CI 1.20-3.13, P = 0.007) in multivariate adjusted models. Studied as a continuous variable, increase in creatinine level by 0.1 mg/dL was associated with an 11% increase in mortality risk and a 7% increase in the combined endpoint. In an unselected cohort of CRT recipients, the baseline creatinine was found to predict worse survival and poor outcome over a modest follow-up duration.

    Joint physical examination is an important outcome in haemophilia; however its relationship with functional ability is not well established in children with intensive replacement therapy. Boys aged 4-16 years were recruited from two European and three North American treatment centres. Joint physical structure and function was measured with the Haemophilia Joint Health Score (HJHS) while functional ability was measured with the revised Childhood Health Assessment Questionnaire (CHAQ₃₈. Two haemophilia-specific domains were created by selecting items of the CHAQ₃₈ that cover haemophilia-specific problems. Associations between CHAQ, HJHS, cumulative number of haemarthroses and age were assessed. A total of 226 subjects - mean 10.8 years old (SD 3.8) - participated; the majority (68%) had severe haemophilia. Most severe patients (91%) were on prophylactic treatment. Lifetime number of haemarthroses [median=5; interquartile range (IQR)=1-12] and total HJHS (median = 5; IQR=1-12) correlated strongly (ρ = 0.51). Total HJHS did not correlate with age and only weakly (ρ=-0.19) with functional ability scores (median=0; IQR=-0.06-0). Overall, haemarthroses were reported most frequently in the ankles. Detailed analysis of ankle joint health scores revealed moderate associations (ρ=0.3-0.5) of strength, gait and atrophy with lower extremity tasks (e.g. stair climbing). In this population, HJHS summating six joints did not perform as well as individual joint scores, however, certain elements of ankle impairment, specifically muscle strength, atrophy and gait associated significantly with functional loss in lower extremity activities. Mild abnormalities in ankle assessment by HJHS may lead to functional loss. Therefore, ankle joints may warrant special attention in the follow up of these children.

    Among patients on long-term anticoagulant therapy who undergo laparoscopic cholecystectomy (LC), bleeding complications have not been extensively investigated. The objective of this study was therefore to investigate postoperative bleeding complications prospectively in patients on chronic oral anticoagulation. In the period of January 2002 to December 2007, 44 patients on long-term anticoagulation with warfarin, an oral anticoagulant (OAC), underwent LC in our center. Oral anticoagulant was discontinued 5 days before the planned date of surgery, and patients were admitted to the hospital 3 days before. Upon admission, bridging anticoagulation with enoxaparin, a low molecular weight heparin (LMWH), was started. When their international normalized ratio (INR) decreased to <1.5, patients underwent LC. In the absence of postoperative bleeding complications, OAC and LMWH were resumed on the evening of the day of surgery, and LMWH was continued until each patient's target INR was reached. A comparison group was comprised by 1,421 consecutively enrolled patients with no comorbid disease who underwent LC during the same period. In the comparison group, postoperative bleeding was encountered in 21 patients (1.5%). In the anticoagulation group, postoperative bleeding was encountered in 11 patients (25%) and ranged from minor oozing from a port incision in one patient to hemorrhage, sepsis, and fatality in one patient. In the anticoagulation group, no significant differences were found between patients with and without postoperative bleeding in terms of age, gender, body mass index, American Society of Anesthesiologists score, INR, or other hemostasis parameters. In patients who underwent LC with bridging anticoagulation, postoperative bleeding was markedly more frequent than expected and was not predicted by the usual coagulation parameters. This suggests a need for methods that can indicate which patients on long-term anticoagulation are at risk for postoperative bleeding.

    Fatal bleeding is a serious consequence of anticoagulant therapy, but factors associated with fatal bleeding during the first 3 months of treatment of venous thromboembolism (VTE) are uncertain. Using data from RIETE, an ongoing registry of consecutive patients with acute VTE, we assessed risk factors for fatal bleeding among all patients. We then used this information to derive a clinical model that would stratify a patient's risk of fatal bleeding during the first 3 months of treatment. Of 24 395 patients, 546 (2.24%) had a major bleed and 135 (0.55%) had a fatal bleed. The gastrointestinal tract was the most common site (40% of fatal bleeds), followed by intracranial bleeding (25%). Fatal bleeding was independently associated with the following factors at the time of VTE diagnosis: age >75 years (OR, 2.16), metastatic cancer (OR, 3.80), immobility > or = 4 days (OR, 1.99), a major bleed within the past 30 days (OR, 2.64), an abnormal prothrombin time (OR, 2.09), a platelet count < 100 x 10(9) L(-1) (OR, 2.23), creatinine clearance < 30 mL min(-1) (OR, 2.27), anemia (OR, 1.54), and distal deep vein thrombosis (OR, 0.39). INR at the time of bleeding is not known. A clinical prediction rule for risk of fatal bleeding that included nine baseline factors was derived. Fatal bleeding occurred in 0.16% (95% CI, 0.11-0.23) of the low-risk, 1.06% (95% CI, 0.85-1.30) of the moderate-risk, and 4.24% (95% CI, 2.76-6.27) of the high-risk category. Patient characteristics and laboratory variables can identify patients at high risk for fatal bleeding during treatment of VTE.

    Background. Human immunodeficiency virus (HIV) infection and associated immune activation predict the risk of cardiovascular disease in resource-rich areas. Less is known about these relationships in sub-Saharan Africa. Methods. Beginning in 2005, we enrolled subjects in southwestern Uganda into a cohort at the time of antiretroviral therapy (ART) initiation. Multiple immune activation measures were assessed before and 6 months after ART initiation. Beginning in 2013, participants aged >40 years underwent metabolic profiling, including measurement of hemoglobin A1c and lipid levels and carotid ultrasonography. We fit regression models to identify traditional and HIV-specific correlates of common carotid intima media thickness (CCIMT). Results. A total of 105 participants completed carotid ultrasonography, with a median completion time of 7 years following ART initiation. Age, low-density lipoprotein cholesterol level, and pre-ART HIV load were correlated with CCIMT. No association was found between CCIMT and any pre-ART biomarkers of immune activation. However, in multivariable models adjusted for cardiovascular disease risk factors, lower absolute levels of soluble CD14 and interleukin 6 and greater declines in the CD14 level and kynurenine-tryptophan ratio after 6 months of ART predicted a lower CCIMT years later (P < .01). Conclusions. Persistent immune activation despite ART-mediated viral suppression predicts the future atherosclerotic burden among HIV-infected Ugandans. Future work should focus on clinical correlates of these relationships, to elucidate the long-term health priorities for HIV-infected people in the region. PMID:26347573

    The distribution of iodine-131 (131I) labelled antibody to carcinoembryonic antigen (CEA) has been studied in 16 patients with colorectal cancer. Levels of tumour and normal tissue radioactivity were measured by serial gamma-camera imaging and counting of blood and urine. Maximum concentrations were found in tumour 8 h after administration and varied up to 9-fold in different patients. Higher levels were found on average in tumour than in any other tissue. Liver, lung and blood were the other tissues in which antibody was concentrated relative to the rest of the body. Antibody cleared from all these tissues over 1 week. Second antibody directed against the antitumour (first) antibody was given 24 h after first antibody in order to accelerate clearance from the blood. This increased the tumour to blood ratio but had little effect on other tissues. Cumulative radiation dose to tumour and normal tissue was estimated. In patients with the most efficient localisation the tumour to body ratio was 20:1 and tumour to blood ratio 5:1. This may be sufficient for effective therapy of cancer in patients selected for efficient antibody localisation. The data may be used to estimate the effect of different therapeutic strategies. For instance, in the time after second antibody administration the average tumour to blood ratio of radiation dose was 11:1, suggesting that two phase systems in which the therapeutic modality is given after a good tumour to normal tissue ratio is obtained may be effective for the majority of patients.

    The clinical significance of energy expenditure (EE) in the treatment of type 2 diabetes has not been fully elucidated. Here we analyzed the relationships between EE and clinical measurements in patients with type 2 diabetes receiving diet therapy. A total of 100 patients (34 women and 66 men) with type 2 diabetes admitted to our hospital for glycemic control were enrolled. The participants received an energy-restricted diet during their hospitalization (median, 15 days). EE was measured in the fasted (FEE) and postprandial (PPEE) states using indirect calorimetry. The postprandial increment of EE (ΔEE) was calculated from the FEE and PPEE (ΔEE=PPEE-FEE). FEE, PPEE, and ΔEE were 0.997±0.203, 1.104±0.213, and 0.107±0.134 kcal/min, respectively. Body weight decreased from 68.7±16.6 to 66.8±16.0 kg (p<0.0001) during hospitalization. FEE and PPEE showed positive correlations with height, body weight, body mass index, and abdominal circumference at admission, but ΔEE was not correlated with these anthropometric measurements. On the other hand, ΔEE was inversely correlated with the body weight change. The association between ΔEE and the body weight change was independent of age, sex, and HbA1c. Postprandial increase in energy expenditure may be a determinant of individual differences in weight reduction in patients with type 2 diabetes on diet therapy. As a simple surrogate for diet-induced thermogenesis, ΔEE may serve as a useful predictive marker for the efficacy of diet therapy.

    The scavenger receptor type B class I(SR-BI) is a receptor for high-density lipoproteins(HDL) and one of entry factors for hepatitis C virus(HCV). We examined the association of single nucleotide polymorphisms(SNPs) of the SCARB1 gene, which encodes SR-BI, with virologic responses to pegylated interferon-based treatment in Asian chronic hepatitis C(CHC) patients. Human genomic and clinical data were collected from 156 consecutive Taiwanese HCV genotype 1 or 2 patients who received pegylated interferon plus ribavirin therapy and 153 non-HCV healthy subjects. Three SNPs(rs10846744, rs5888, and rs3782287) of the SCARB1 gene that have been linked to humans diseases were investigated. rs10846744 rather than rs5888 or rs3782287 was associated with serum HCV RNA level and sustained virologic response(SVR) to pegylated interferon plus ribavirin therapy in CHC patients(GG vs. non-GG genotype, Adjusted Odds Ratio, 95% CI: 0.32, 0.11–0.95, P = 0.039). Among patients with IL28B rs8099917 non-TT genotypes, those with rs10846744 non-GG genotype had a higher SVR rate than those with GG genotypes. In addition, patients with GG genotype had a higher fasting blood glucose level than those with CC genotype. In conclusion, SCARB1 gene polymorphisms may serve as a potential predictor of treatment responses in CHC patients receiving interferon-based therapy. (ClinicalTrials.gov number, NCT02714712).

  15. How can we ensure effective antibiotic dosing in critically ill patients receiving different types of renal replacement therapy?

    Determining appropriate antibiotic dosing for critically ill patients receiving renal replacement therapy (RRT) is complex. Worldwide unstandardized and heterogeneous prescribing of RRT as well as altered patient physiology and pathogen susceptibility all cause drug disposition to be much different to that seen in non-critically ill patients. Significant changes to pharmacokinetic parameters, including volume of distribution and clearance, could be expected, in particular, for antibiotics that are hydrophilic with low plasma protein binding and that are usually primarily eliminated by the renal system. Antibiotic clearance is likely to be significantly increased when higher RRT intensities are used. The combined effect of these factors that alter antibiotic disposition is that non-standard dosing strategies should be considered to achieve therapeutic exposure. In particular, an aggressive early approach to dosing should be considered and this may include administration of a 'loading dose', to rapidly achieve therapeutic concentrations and maximally reduce the inoculum of the pathogen. This approach is particularly important given the pharmacokinetic changes in the critically ill as well as the increased likelihood of less susceptible pathogens. Dose individualization that applies knowledge of the RRT and patient factors causing altered pharmacokinetics remains the key approach for ensuring effective antibiotic therapy for these patients. Where possible, therapeutic drug monitoring should also be used to ensure more accurate therapy. A lack of pharmacokinetic data for antibiotics during the prolonged intermittent RRT and intermittent hemodialysis currently limits evidence-based antibiotic dose recommendations for these patients.

    Music therapy is a popular form of complementary therapy used in the hospice in Western countries, as people who are terminally ill have several needs arising directly from the disease process. In the area of palliative care, no systematic review has been conducted on the experience of patients using music therapy from the qualitative perspective. Hence, a synthesized summary of the experience of music therapy is presented. The aim of this review was to critically analyse and synthesize existing evidence related to terminally ill patients' experiences of using music therapy in the palliative setting. This review considered quantitative descriptive studies, and qualitative research with adult participants who were terminally ill receiving palliative care in a hospital, an in-patient hospice, a nursing home, or their own homes, regardless of their diagnosis who had undergone at least one music therapy session with a trained music therapist and were not cognitively impaired. Healthcare workers who have witnessed patients participating in music therapy were also included in the review. Only published primary research studies were included in the review. This review was limited to papers in English. A three-step search strategy was undertaken. First, an initial limited search of CINAHL and MEDLINE was done. Second, an extensive search using all identified keywords and index terms across all included databases was done. Finally, a hand search of the reference lists and bibliographies of included articles was conducted METHODOLOGICAL QUALITY: Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using the standardised critical appraisal instruments from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (QARI) for qualitative papers, and Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) for quantitative descriptive papers

    Introduction The 30-day case-fatality rate after acute myocardial infarction (MI) for rheumatoid arthritis (RA) patients is twice that of the general population. This study compared the frequency and timeliness of early reperfusion therapy and treatment with secondary prevention medications after acute MI in RA patients and controls. Methods We performed a structured medical chart review of RA patients and matched controls who had been admitted with acute MI to one of three hospitals in Victoria, Australia, between 1995 and 2005. The administration and timing of acute reperfusion therapy and in-hospital treatment with secondary prevention medications were compared between the two groups. Acute reperfusion was defined as thrombolysis or percutaneous coronary intervention (PCI) within 12 hours of the first symptom of MI. Results The medical charts of 90 RA patients and 90 matched controls were reviewed. The RA patients were significantly less likely to receive acute reperfusion compared with the controls (16% versus 37%: odds ratio (OR), 0.27; 95% confidence interval (CI), 0.10 to 0.64)), and this difference persisted after adjusting for type of MI, clinical setting of MI, and prior MI (OR, 0.2; 95% CI, 0.05 to 0.6). The RA patients also received less-frequent in-hospital treatment with beta blockers (71% versus 83%; OR, 0.42; 95% CI, 0.18 to 0.96) and lipid-lowering agents (40% versus 70%; OR, 0.21; 95% CI, 0.09 to 0.46). Conclusions RA patients who experience acute MI receive acute reperfusion and secondary prevention medications less frequently than do controls. This may contribute to higher case-fatality rates after MI in RA patients. PMID:20929534

    The purpose of this study was to evaluate a receiver operating characteristic (ROC) curve method to determine dose thresholds with late genitourinary (GU) toxicity after stereotactic body radiation therapy for prostate cancer. Seventy-eight patients diagnosed with low- to intermediate-risk prostate cancer and treated with stereotactic body radiation therapy alone were reviewed retrospectively. All patients received a total dose of 38 Gy in 4 fractions with a planning target volume expansion of 2 mm. GU toxicity was documented according to the Common Terminology Criteria for Adverse Events, version 4. ROC analysis applied on a logistic regression model was used to determine optimal dosimetric parameters for GU toxicity. The median age at treatment was 69 years with a median prostate volume of 46.2 mL. The median prescription isodose line was 67% (interquartile range, 65, 70). The median clinical follow-up was 35.49 months. Late grade 1, 2, and 3 GU toxicity occurred in 21.8%, 19.2%, and 2.6% of cases, respectively. Late grade 2+ GU toxicity was associated with prescription to isodose line (P = .009) and normalized volumes for heterogeneity ≥46 Gy. The ROC method successfully produced thresholds for dose-volume recommendations for both prostate and urethra, including normalized prostate volumes from 46 to 50 Gy, such as volume of target tissue receiving 46% of the prescribed dose (V46) Gy of 36.7% (sensitivity, 71%; specificity, 61%; area under the curve, 0.67) with an associated probability of late GU grade 2+ toxicity of 21%. Intraprostatic heterogeneity should be controlled with potential thresholds at V46 Gy <36.7%, V48 Gy <21%, and V50 Gy <9.5% of the normalized prostate volume to keep late grade 2+ GU toxicity ≤20% with 4-fraction schemes. This may be facilitated with a higher prescription isodose line (>69%). Copyright © 2016 American Society for Radiation Oncology. Published by Elsevier Inc. All rights reserved.

    Purpose Neuropathy is a common and potentially disabling complication of adjuvant taxane therapy. Recent studies have identified candidate single nucleotide polymorphisms associated with taxane-induced neuropathy. Therefore, we sought to determine whether neuropathy was associated with breast cancer recurrence in a clinical trial population who received adjuvant taxane therapy. Patients and Methods Trial E1199 included 4,554 eligible women with operable breast cancer who received up to four cycles of doxorubicin and cyclophosphamide every 3 weeks followed by paclitaxel 175 mg/m2 every 3 weeks for four cycles (P3), paclitaxel 80 mg/m2 weekly for 12 cycles (P1), docetaxel 100 mg/m2 every 3 weeks for four cycles (D3), or docetaxel 35 mg/m2 weekly for 12 cycles (D1). A Cox proportional hazards model was used to determine the relationship between neuropathy and disease-free survival (DFS), overall survival (OS), and recurrence-free survival (RFS) by treating neuropathy status as a time dependent covariate and using a landmark analysis. Results Of 4,554 patients who received at least one taxane dose, grade 2 to 4 neuropathy developed in 18%, 22%, 15%, and 13% of patients in the P3, P1, D3, and D1 arms, respectively. In a model that included age, race, obesity, menopausal status, tumor size, nodal status, treatment arm, neuropathy, and hyperglycemia, no significant relationship was found between neuropathy and DFS, OS, or RFS. Conclusion There was no association between taxane-induced neuropathy and outcome. PMID:22851566

    Randomized controlled trials support the use of dignity therapy (DT) in palliative care patients late in the course of their disease, but little is known about the feasibility of DT earlier in the course in patients with incurable malignant disease who are still receiving chemotherapy. To assess the feasibility of DT relatively early in the disease trajectory (primary endpoint) and the effect on death acceptance, distress, symptoms, quality of life, peacefulness, and advanced care planning (secondary outcome endpoint). Stage IV colorectal cancer patients who progressed on first-line chemotherapy were enrolled. Patients received DT over 2 visits and had outcome measures assessed pre-DT, immediately post-DT and 1 month post-DT. 15 of 17 patients (88%) who were approached enrolled in the study. Most of the patients who completed DT reported being satisfied and felt it was helpful, that it increased their sense of meaning, that it would be helpful to their family, and that it increased their sense of dignity, their sense of purpose, and their will to live. This is a small study that lacks power for statistical significance of findings. There is no control group for comparison. DT is a highly feasible, satisfying, and meaningful intervention for advanced colorectal cancer patients who are receiving chemotherapy earlier in the course of their and may result in an understanding of disease and goals of care at the end of life. Larger feasibility and exploratory studies are warranted in advanced cancer patients. ©2014 Frontline Medical Communications.
